As shown in Figures 2-6, this embodiment provides a cutting device, including:

knife seat 1;

There are a plurality of knives 2 arranged on the knife seat 1, and there is a preset distance between two adjacent knives 2;

The moving structure connected with the knife seat 1 is used to control the movement of the knife seat 1 in a preset direction so that the corresponding knife 2 cuts the product to be cut in a preset direction;

The rotating structure connected with the knife seat 1 is used to control the rotation of the knife seat 1 so that the knife 2 adjacent to the current knife 2 contacts the surface of the product to be cut.

The rotatable setting of multiple knives 2 realizes that when jumping is required for cutting, only the knife seat 1 needs to be rotated so that the knives 2 adjacent to the current knives 2 are in contact with the surface of the product to be cut, and the jumping is realized by replacing the cutting knives 2 Type cutting, as shown in Figure 5 and Figure 6, Figure 5 shows a schematic diagram of the state when the tool a cuts to the position where it needs to jump, rotate the knife seat 1, and the cutting tool is switched to the tool b adjacent to the tool a, Figure 6 shows It is a schematic diagram of changing to cutter b. Compared with FIG. 5 and FIG. 6, there is a preset distance between adjacent cutters, and the contact point between cutter b and the product 30 to be cut and the contact point between cutter a and the product sheet 30 to be cut is In the area where jumping is required, jumping cutting can be realized by rotating and switching the tool, without slowing down, improving production efficiency, and during the process of changing the tool 2, the distance between the tool holder 1 and the product to be cut is constant , reducing the risk of product breakage to be cut.

The setting of the preset distance is determined according to factors such as the cutting speed of the cutter 2 and the length of the jumping area.

The specific structural forms of the tool holder 1 can be various. In this embodiment, the tool holder 1 includes a rotating disk, and a plurality of the cutters 2 are arranged at intervals on the outer peripheral surface of the rotating disk.

The number of cutters 2 can be set according to actual needs. In this embodiment, six cutters 2 are arranged on the outer peripheral surface of the rotating disk, but it is not limited thereto.

In this embodiment, a plurality of the knives 2 are detachably arranged on the rotating disk, which facilitates the replacement of the knives 2 .

There are many ways to connect the cutter 2 to the rotating disk, as long as the detachable connection between the cutter 2 and the rotating disk is realized, the cutter 2 can be stably installed by means of bolt installation or the like. on the outer peripheral surface of the rotating disk.

In order to ensure that the cutting point between the switched cutter 2 and the product to be cut is located on the extension line of the straight line where the cutting path of the original cutter 2 is located, in this embodiment, the connection between the cutter 2 and the rotating disk adopts a clamping method Under the premise of ensuring that the cutter 2 will not be separated from the rotating disk, it is subjected to the centrifugal force of rotation during rotation, so as to prevent the cutter 2 from swinging left and right to make the cutting point shift and affect the cutting quality.

In this embodiment, a plurality of clamping holes 111 are provided on the outer peripheral surface of the rotating disk at intervals of the predetermined distance, and the first end of each of the cutters 2 is provided with a clamp corresponding to the clamping holes 111. Connector 23.

The specific structural forms of the clamping hole 111 and the clamping member 23 can be various, as long as the clamping of the tool 2 and the rotating disk is realized. In this embodiment, the clamping hole The inner wall of 111 is provided with a protrusion, and the first end of the tool 2 is provided with a cylindrical insertion area adapted to the engaging hole 111, and the outer peripheral surface of the insertion area is provided with a groove.

Specifically, the protrusion is an annular protrusion, and the groove is an annular groove.

In this embodiment, the cutter 2 includes a second end opposite to the first end, and the second end has a mounting portion for mounting the blade 3 .

In this embodiment, the blade 3 is a wheel-shaped structure, but it is not limited thereto.

Further, a strip-shaped opening is opened in the middle area of the end surface of the second end, and a slot 21 is formed by moving along the opening toward the direction close to the first end, and through holes are correspondingly opened on both side walls of the slot 21, the Both sides of the blade 3 are respectively provided with inserting parts that can pass through the through holes.

Further, when the cutter 2 is cutting, the length direction of the opening is parallel to the preset direction, and the edge surface of the blade 3 is parallel to the preset direction.

Further, the end faces of part of the second end are recessed in a direction close to the first end, so that a side surface of the installation part forms a slope 22 .

The setting of the slope 22 makes the area of the installation part smaller, which increases the operable space when the tool 2 is installed, and facilitates the installation of the tool 2 .

In this embodiment, the rotating structure includes a transmission shaft 5 connected to the rotating disk, the transmission shaft 5 is located on the first side of the center of the rotating disk, and the first side is that the center of the circle is close to the Cut one side of the product.

When the cutting tool 2 is switched, the cutting tool 2 adjacent to the current cutting tool 2 is subjected to a downward force when falling, which is beneficial for the cutting point of the replaced cutting tool 2 to be located on the production piece to be cut on the extension line of the cutting path of the current cutting tool 2 On, to avoid the deviation of the cutting position, to ensure the cutting quality.

It should be noted that, in order to avoid excessive force on the tool when it goes down the road, the distance between the transmission shaft and the center of the rotating disk should not be too large.

In this embodiment, in order to avoid cracks on the surface of the product to be cut when the cutting tool 2 is switched, in this embodiment, the rotating structure controls the rotation preset speed of the knife seat 1 to prolong the falling time of the blade 3, Make the blade 3 fall slowly, and when the blade 3 falls into contact with the product to be cut, and then press it in to cut the product to be cut, keep a relatively long pressing time to avoid penetrating cracks caused by the drop.

In this embodiment, the moving structure includes a bracket 4 connected to both sides of the transmission shaft 5 , and a drive unit drivingly connected to the bracket 4 .

In this embodiment, the bracket 4 is a U-shaped structure, and two side walls of the U-shaped structure are provided with through holes through which the transmission shaft can pass.

In this embodiment, a plurality of installation surfaces 11 are provided on the outer peripheral surface of the rotating disk, and the installation surfaces 11 are planar structures, and the number of the installation surfaces 11 corresponds to the number of the knives 2 .

The arrangement of the installation surface 11 with a planar structure facilitates the installation and removal of the cutter 2 .

The above is a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, some improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications It should also be regarded as the protection scope of the present invention.
