A driving sprocket 6 is installed at the output end of the motor 5. The outer wall of the driving sprocket 6 and the driven sprocket 4 is chain-connected with a chain 7. The driving sprocket 6 can rotate under the drive of the motor 5, and then the chain 7 can move. A plurality of slide bars 8 are inserted into the inner cavity of the slide 3. The outer wall shape of the slide bar 8 is cylindrical. The slide bar 8 is convenient to use. The sliding of the movable plate 10 in the slide 3 is smoother with its own curved surface. The outer walls of two adjacent slide bars 8 are installed with movable plates 10. The movable plates 10 are kept horizontal, so that the packaging machine and the upper surface of the movable plates 10 can form a sealing state, so that the packaging machine can absorb vacuum. The outer wall of the slide bar 8 located on the right side of the movable plate 10 is sleeved with one end of the connecting rod 9, and the other end of the connecting rod 9 is connected to the chain 7 through a pin shaft. The slide bar 8 slides in the slide 3, and the connecting rod 9 can pull the movable plate 10 to move. The outer wall of the movable plate 10 is fixedly connected with a positioning mechanism 11, and a limiting block 12 is installed at the front end of the outer wall of the movable plate 10. A counting mechanism 13 is fixedly connected to the upper right corner of the front face of the vertical plate 2 on the front side. The counting mechanism 13 cooperates with the limiting block 12 to realize the statistics of the number of product packaging completed.

As a preferred solution, further, the positioning mechanism 11 includes a support seat 111 fixedly connected to the front and rear ends of the outer wall of the movable plate 10. The support seat 111 is semicircular in shape. A plurality of positioning blind holes 112 are equidistantly provided on the upper surface of the support seat 111 along the circumferential direction. A support plate 113 is connected to the center of the inner bottom of the support plate 113 through a pin shaft. The product packaging bag is supported by the support plate 113. The upper and lower ends of the right side wall of the support plate 113 are respectively installed with a limit strip 114 and a pad 115. The limit strip 114 blocks the bag opening of the packaging bag to prevent the material in the packaging bag from overflowing, and can also cooperate with the heating strip of the packaging machine to hot-melt seal the packaging bag. The pad 115 and the support plate 113 are arranged perpendicular to each other. The packaging bag is lifted up by the pad 115 to prevent the packaging bag from falling off the support plate 113. A limit rod 116 is vertically installed at the center of the inner cavity of the support plate 113. The upper and lower ends of the outer wall of the limit rod 116 are respectively sleeved with a spring 117 and a lifting rod 118. The lifting rod 118 is pushed down under the elastic force of the spring 117. Insert rods 119 are installed at the front and rear ends of the lower surface of the lifting rod 118. The insert rod 119 is inserted into the inner cavity of the positioning blind hole 112 to position the support plate 113. The bottom shape of the insert rod 119 is conical, which facilitates the insert rod 119 to enter the positioning blind hole 112.

As a preferred solution, further, the counting mechanism 13 includes a box body 131 fixedly connected to the upper right corner of the front face of the vertical plate 2 located at the front side, a counter 132 is installed on the front face of the box body 131, and the number of product packages is accumulated and counted by the counter 132, a first contact 133 is installed on the front side of the inner cavity of the box body 131, and a U-shaped plate 134 that can slide up and down is inserted into the inner cavity of the box body 131, and guide grooves 135 are provided on both sides of the U-shaped plate 134, and a counterweight block 136 is installed on the lower surface of the U-shaped plate 134, through the counterweight block The weight block 136 increases the gravity of the U-shaped plate 134. An inner rod 137 is installed on the front side of the inner cavity of the box body 131 along the front-to-back direction, and the inner rod 137 is located at the bottom of the first contact 133. The outer wall of the inner rod 137 is sleeved with an outer rod 138 that can slide forward and backward. The outer wall of the inner rod 137 is rectangular in shape to ensure that the outer rod 138 does not rotate. A second contact 139 electrically connected to the counter 132 is installed on the front end of the upper surface of the outer rod 138. The second contact 139 and the first contact 133 are located on the same straight line, and both are semicircular in shape. When the outer rod 138 moves forward, it is ensured that the second contact 139 and the first contact 133 can contact each other, and an electrical signal is sent to the counter 132 to make the counter 132 count once. The left and right rear ends of the outer rod 138 are both equipped with guide pillars 1310, and the guide pillars 1310 are plugged into the inner cavity of the guide groove 135. The guide groove 135 is arranged on the outer wall of the U-shaped plate 134 from top to bottom and tilted to the front side. When the U-shaped plate 134 descends under the action of its own gravity, the guide groove 135 can squeeze the guide pillar 1310 backward, thereby making the outer rod 138 When the outer rod 138 moves backward, a roller 1311 is installed on the rear side of the outer rod 138. The roller 1311 and the limit block 12 are in the same straight line. The limit block 12 is triangular in shape. When the movable plate 10 moves to the right, the right inclined surface of the limit block 12 can squeeze the roller 1311 to move forward, allowing the outer rod 138 to move forward, so that the second contact 139 contacts the first contact 133. When the left inclined surface of the limit block 12 contacts the roller 1311, the roller 1311 gradually moves backward under the gravity of the U-shaped plate 134 to buffer the movement of the outer rod 138.

Working principle:

Step 1: The packaging machine is placed on the right end of the upper surface of the vertical plate 2, and the staff stands on the left side of the vertical plate 2, with the purpose of placing the packaging bag containing the product on the positioning mechanism 11;

Step 2: According to the different types of products in the packaging bag, in order to prevent the product from overflowing and facilitate the sealing of the packaging bag, the inclination angle of the support plate 113 is adjusted, and the lowering rod 118 is lifted. The lifting rod 118 moves up along the limiting rod 116 and compresses the spring 117, so that the insertion rod 119 is moved out of the positioning blind hole 112, and the positioning of the support plate 113 is released. According to the type of product, the angle of the support plate 113 is changed, and the lifting rod 118 is loosened. Under the elastic force of the spring 117, the insertion rod 119 is inserted into the positioning blind hole 112 at the corresponding position to position the support plate 113, and the packaging bag is placed on the pad 115, and the packaging bag is supported by the support plate 113 and the pad 115;

Step 3: The motor 5 drives the driving sprocket 6 to rotate, so that the sprocket 7 rotates clockwise, and the sliding rod 8 moves along the slideway 3 under the traction of the connecting rod 9, and the moving plate 10 moves from left to right, so that the positioning mechanism 11 can reach the bottom of the packaging machine in order to package;

Step 4: The upper cover of the packaging machine descends and contacts the movable plate 10 to form a closed space, and vacuum is performed to remove the gas in the packaging bag. Then, the heating strip in the upper cover of the packaging machine heats the bag opening to achieve hot-melt sealing of the packaging bag.

Step 5. After the packaging is completed, as the movable plate 10 moves from left to right, the right side inclined surface of the limit block 12 squeezes the roller 1311 to the rear side, prompting the outer rod 138 to move forward along the inner rod 137, and the guide column 1310 squeezes the guide groove 135 upward, prompting the U-shaped plate 134 to move upward. When the roller 1311 reaches the top of the limit block 12, the second contact 139 contacts the first contact 133 to form a passage, and sends an electrical signal to the counter 132. The counter 132 counts once. When the left side inclined surface of the limit block 12 contacts the roller 1311, when the U-shaped plate 134 drops due to gravity, the guide groove 135 squeezes the guide column 1310 backward, prompting the roller 1311 to gradually move backward, the second contact 139 separates from the first contact 133, and the roller 1311 returns to the initial position. As the upper limit block 12 of the movable plate 10 squeezes the roller 1311, the product packaging quantity is counted.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
