On the shell of the machine, placed above the traction roller 1, second U-shaped support frames 103 are arranged on both sides of the top of the support platform 104, a first fixed shaft 2 is slidably connected between the two first U-shaped support frames 102, a rubber roller 201 is rotatably connected to the first fixed shaft 2, and a plurality of first circular grooves 202 are provided on the rubber roller 201, a second fixed shaft 3 is slidably connected between the two second U-shaped support frames 103, an aluminum guide roller 301 is rotatably connected to the second fixed shaft 3, and a plurality of second circular grooves are provided on the aluminum guide roller 301, and a round belt 203 is sleeved between the first circular groove 202 and the second circular groove.

[0020] Through the arrangement and cooperation of the rubber roller 201, the aluminum guide roller 301 and the round belt 203, the rotation of the traction roller 1 is utilized to drive the rubber roller 201, the aluminum guide roller 301 and the round belt 203 to start rotating, so that the soft material will not be scratched by the rubber roller 201 when passing between the traction roller 1 and the rubber roller 201, and the round belt 203 will move the soft material toward the cutting knife 101 and limit the soft material due to the fit of the soft material, which greatly improves the smoothness of the soft material passing. The structural arrangement is simple and efficient, and is suitable for popularization and use.

[0021] Among them, it needs to be supplemented that the tops of the two first U-shaped support frames 102 are fixedly connected with long top plates 205, and the two ends of the inner top surfaces of the long top plates 205 are fixedly connected with cylinders 204, and the ends of the cylinders 204 are fixedly connected to the first fixed axis 2, and the tops of the second U-shaped support frames 103 are fixedly connected with convex cover plates 302, and the convex cover plates 302 are slidably connected with threaded rods 303, and the bottom ends of the threaded rods 303 pass through the second fixed axis 3, and the threaded rods 303 are located on the upper and lower sides of the convex cover plates 302 and are threadedly connected with first fastening nuts, and the bottom ends of the threaded rods 303 are threadedly connected with second fastening nuts.

[0022] Among them, it should be supplemented that the first circular groove 202 is opened at equal distances on the rubber roller 201, the second circular groove is opened at equal distances on the aluminum guide roller 301, the round belt 203 is embedded in the first circular groove 202, the depth of the first circular groove 202 is greater than the diameter of the round belt 203, the round belt 203 is vertically arranged to the rubber roller 201, and the rubber roller 201 is parallel to the aluminum guide roller 301. It should be noted that, through such an arrangement, the round belt 203 can be prevented from directly contacting the traction roller 1, so that the soft material is not squeezed and deformed by the round belt 203 when passing through the traction roller 1, and the round belt 203 is vertically arranged to the rubber roller 201 and the rubber roller 201 is parallel to the aluminum guide roller 301, so that the rubber roller 201 and the aluminum guide roller 301 can rotate more flexibly, which is beneficial to the movement of the soft material.

[0023] Working principle: When using this device, when the soft material passes through the traction roller 1, due to the rotation of the traction roller 1 and the rubber roller 201 being attached to the soft material under the action of the cylinder 204 extending downward, the soft material moves toward the cutting knife 101. In this process, since the depth of the first circular groove 202 is greater than the diameter of the round belt 203, the round belt 203 does not contact the traction roller 1, thereby ensuring that the soft material is not squeezed and deformed by the round belt 203 when passing through the traction roller 1. The rubber roller 201 The round belt 203 starts to rotate, and the aluminum guide roller 301 also starts to rotate through the transmission of the round belt 203. The round belt 203 will also rotate between the rubber roller 201 and the aluminum guide roller 301. After passing between the traction roller 1 and the rubber roller 201, the soft material enters the top of the supporting platform 104. Because the round belt 203 fits the soft material, it continues to move toward the cutting knife 101 under the friction of the round belt 203. The round belt 203 is located directly above the soft material, and the soft material is successfully limited.

[0024] During use of the device, the height of the second fixed axis 3 can be adjusted by adjusting the position of the first fastening nut or the second fastening nut on the threaded rod 303, so that the gap between the round belt 203 and the supporting platform 104 can be conveniently adjusted according to the thickness of the soft material, thereby improving the flexibility of the mechanism, and the structure is simple, easy to operate, and suitable for popularization and use.

[0025] 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.
