A roller 177 is installed on the end of the rotating arm 172 away from the slider 174 , and the roller 177 is tangent to the action block 179 extending from the bottom of the moving base 15 . , the third elastic member 173 is a coil spring 178, the inner wall of the installation cavity is extended with a rotating shaft that guides the rotation of the rotating arm 172, the rotating shaft is extended with a central axis, the central hole of the rotating arm 172 is a rotating hole, and the rotating hole and the central axis are convoluted There is a coil spring 178, the inner end of the coil spring 178 is fixed with the central axis, the outer end of the coil spring 178 is fixed with the inner wall of the rotating hole, and the roller can also be kept under the elastic force of the coil spring 178 when the third conveyor belt 14 is located close to the first conveyor belt 11. 177 has no pressing force on the movable base 15 . When the blood bag 9 needs to be installed between the third conveyor belt 14 and the first conveyor belt 11, first, step on the pedal 176, the guide seat 175 is lowered, the slider 174 moves toward the center of the rotating arm 172, the rotating arm 172 rotates, and the roller 177 squeezes Press the action block 179, and the action block 179 drives the moving base 15 and the third conveyor belt 14 to move, the third conveyor belt 14 is far away from the first conveyor belt 11, and the distance between the first conveyor belt 11 and the third conveyor belt 14 is enlarged.

The top of the installation cavity communicates with the outside, so that the movable seat 15 has a sliding space.

In order to prevent impurities from entering from the top of the installation cavity and hinder the operation of the second spring and the pedal driving mechanism 17, the following design is made: the side of the installation frame 13 is recessed to form a guide groove, the guide groove communicates with the installation cavity, and a guide groove is inserted into the guide groove. The closing plate 130, the closing plate 130 can move under the guidance of the guide groove, the closing plate 130 will not move in the vertical direction under the action of the inner wall of the guide groove, and there is an insertion rod 131 on the surface of the closing plate 130, and the insertion rod 131 is inserted to move In the socket opened by the seat 15 , the outer wall of the insertion rod 131 is recessed to form a clamping hole, and the inner wall of the socket is protruded with a convex portion 132 . The action block 179 passes through the closing plate 130 and is fixed to the lower end of the insertion rod 131. The connection between the action block 179 and the insertion rod 131 forms a step, and the step restricts the action block 179 and the insertion rod 131 from moving downward relative to the closing plate 130. The third When the conveyor belt 14 moves, the closing plate 130 always closes the installation cavity, one end of the second spring is connected to the action block 179 oppositely, and the other end of the second spring is connected to the inner wall of the installation cavity.

Both ends of the second spring are annular structures, the inner wall of the installation cavity is formed with a first limiting rod 133 inserted into one end of the second spring, and a rod body 134 is inserted into the inner wall of the installation cavity, the rod body 134 passes through the center of the second spring, and the rod body 134 Passing through a mounting plate 135, a second limiting rod 136 inserted into the other end of the second spring is formed on one side of the mounting disk 135, and a hemisphere 137 is fixed on the side of the mounting disk 135 away from the first limiting rod 133.

The rod body 134 is a cuboid structure, and the mounting plate 135 cannot rotate relative to the rod body 134.

Since the movable seat 15 needs to move, and the relatively fixed action block 179 of the movable seat 15 needs to interact with the pedal driving mechanism 17, the top of the installation cavity needs to be communicated with the outside world, in order to prevent impurities from entering the installation cavity and affecting the operation of the pedal driving mechanism 17.

The steps for installing the closing plate 130 and the second spring are as follows; first, hook one end of the second spring on the second release limiting rod 136; then, pass the rod body 134 through the mounting plate 135 and the hemisphere 137, and the action block 179 can also supply The rod body 134 passes through; then, the mounting plate 135, the hemisphere 137, the rod body 134 and the second spring are put into the mounting cavity together; then, the other end of the second spring is hooked on the first limiting rod 133; Then, insert the rod body 134 into the inner wall of the installation cavity to support the second spring and ensure that the installation plate 135 hooks the second spring; then, insert the closing plate 130 into the guide groove; and finally, put the action block 179 Passing through the closing plate 130, since the hemisphere 137 is closer to the first conveyor belt 11 when the second spring is at its natural elongation length, when the action block 179 is inserted, the bottom surface of the action block 179 presses the hemisphere 137, so that the hemisphere 137 faces the first conveyor belt 11. When the release-limiting rod 133 moves, the second spring is compressed, so that the elastic force of the second spring can be maintained to clamp the blood bag 9. At this time, the hook hole on the mounting plate 135 is aligned with the hook rod 138, and the action block 179 is further lowered to move the hook rod. 138 is inserted into the hook hole to realize the relative connection between the second spring and the action block 179; finally, the movable seat 15 on which the third conveyor belt 14 is installed is covered on the insertion rod 131, and the clamping hole on the insertion rod 131 is in the movable seat 15. The convex portion 132 is snap-fitted to realize the installation. It is convenient to install the second spring and the closing plate 130, and realize that the second spring can be replaced by opening the closing plate 130. After the edge sealing, the second spring is replaced when the elastic force is lost, so as to ensure that the first conveyor belt 11 and the third conveyor belt 14 are aligned. The clamping force of the plasma bag 9.

Two pressing surfaces, the first pressing surface is close to the second pressing surface, a fourth spring is installed between the two mounting arms 22, and the two stick bodies 21 can be kept away from each other under the elastic force of the fourth spring.

When the plasma bag 9 is squeezed, the third vertical drive mechanism 4 is raised, and the two stick bodies 21 with a large distance are transported to the top of the plasma bag 9, and the stick bodies 21 are not in contact with the plasma bag 9 at this time; then, the cylinder is gathered 31 raises the drive block 32, the drive block 32 squeezes the two mounting arms 22 closer to each other, and the two stick bodies 21 clamp the plasma bag 9; finally, the third vertical drive mechanism 4 is lowered, the two stick bodies 21 are lowered, and the two stick bodies 21 are clamped.
