[0032] The specific arrangement and function of the limiting device 5 and the clamping device 6 will be described in detail below.

[0033] like Figure 1 and Figure 2 as well as Figure 3 As shown, the limiting device 5 includes two mounting plates 51, which are respectively fixedly connected to the second fixed plate 46 and the second movable plate 47 on the side close to the mounting frame 2.

The surface of the slide bar 52 is covered with a spring 53, and the two ends of the spring 53 are fixedly connected to the mounting plate 51 and the pull plate 54 respectively. By providing the spring 53, the position of the slide bar 52 can be limited, and by providing the pull plate 54, the installation of the spring 53 is facilitated.

[0035] like Figure 2 and Figure 4 as well as Figure 5 As shown, the clamping device 6 includes two "L"-shaped plates 61, and the two "L"-shaped plates 61 are fixedly connected to the upper surface of the baffle plate 55. The inner walls of the two "L"-shaped plates 61 are threaded with a first screw rod 62, and the end of the first screw rod 62 close to the limiting plate 58 is fixedly connected to the abutment plate 64. By setting the "L"-shaped plate 61, the first screw rod 62 and the abutment plate 64 can be installed, and the abutment plate 64 can be controlled by the first screw rod 62 to move close to or away from the limiting plate 58, so that the plastic film can be limited or the restriction on the plastic film can be released by the limiting plate 58. The end of the first screw rod 62 away from the abutment plate 64 is fixedly connected to the rotating plate 63, and the two sides of the two mounting plates 51 are fixedly connected to the bent rods 65, and the four bent rods 65 are slidably connected to the inner walls of the second fixed plate 46 and the second movable plate 47 respectively. By setting the rotating plate 63, the first screw 62 can be easily rotated and the position of the first screw 62 can be limited. By setting the bending rod 65, the connection between the mounting plate 51 and the second fixed plate 46 and the second movable plate 47 is ensured while the mounting plate 51 can be moved.

[0036] The second fixed plate 46 and the second movable plate 47 are both fixedly connected with an arc plate 66 on one side close to the mounting plate 51, and the inner wall of the arc plate 66 is threadedly inserted with a second screw 67. By providing the arc plate 66, the second screw 67 can be installed, and by providing the second screw 67, the position of the mounting plate 51 can be restricted or the restriction on the position of the mounting plate 51 can be released.

[0037] Working principle: When using the plastic film cutting device to cut the plastic film, first connect the plastic film cutting device to an external power supply, then move the feed roller 48 wrapped with the plastic film between the second fixed plate 46 and the second movable plate 47 of the mounting mechanism 4, and then install the discharge roller 44 between the first fixed plate 42 and the first movable plate 43, respectively control the second movable plate 47 and the first movable plate 43 to approach the second fixed plate 46 and the first fixed plate 42, fix the feed roller 48 and the discharge roller 44, and then pull the plastic film close to the discharge roller 44 to complete the preparation for cutting the plastic film, start the cutter 3 on the mounting frame 2 and start the discharge roller 44 at the same time, control the cutting and conveying of the plastic film, and by setting the base 1, the first rectangular plate 41, the second rectangular plate 45 and the mounting frame 2 can be installed. When installing the plastic film on the discharge roller 44, first move the limit plate 58 so that the slider 59 slides on the surface of the slide groove on the baffle 55, so that the limit plate 58 moves away from the support plate 56, and then control the plastic film to pass through the support plate 56 to approach the discharge roller 44 to install the plastic film. In the process of starting the plastic film cutting device to cut the plastic film, the discharge roller 44 drives the plastic film to pass through the ball 57. When the cutter 3 cuts the plastic film, the cutter 3 drives the plastic film to move, so that the plastic film pushes the baffle 55, so that the slide bar 52 slides on the inner wall of the installation plate 51. When the cutter 3 finishes cutting the plastic film, the spring Under the action of the elastic force of the spring 53, the baffle 55 moves back to its original position. By setting the pull plate 54, the spring 53 can be installed. By setting the spring 53, the position of the slide bar 52 can be limited. At the same time, it can move with the plastic film during the cutting process, thereby minimizing the folding of the plastic film. By setting the limiting device 5, the two sides of the plastic film can be limited when the plastic film is cut by the plastic film cutting equipment, so that the folding of the plastic film can be avoided as much as possible during the transportation of the plastic film for cutting, thereby ensuring the cutting effect of the plastic film as much as possible.

[0038] When the plastic film on the feed roller 48 is reduced to a level that is insufficient to wrap around the feed roller 48, the rotating plate 63 drives the first screw 62 to rotate on the inner wall of the "L"-shaped plate 61, so that the abutment plate 64 moves close to the limit plate 58, so that the limit plate 58 and the support plate 56 fix the plastic film, and then the second screw 67 is rotated to rotate on the inner wall of the arc plate 66, thereby controlling the second screw 67 to move away from the mounting plate 51, and releasing the restriction on the position of the mounting plate 51. At this time, the movement of the plastic film drives the mounting plate 51 to move, so that the plastic film can be utilized as much as possible. By providing the bent rod 65, the connection between the mounting plate 51 and the second fixed plate 46 and the second movable plate 47 is ensured, while the mounting plate 51 can be moved. By providing the clamping device 6, the plastic film can be clamped when the length of the plastic film on the feed roller 48 is short, and the cutting of the plastic film can be continued, thereby ensuring the utilization of the plastic film as much as possible while avoiding the danger of manual operation by the staff.
