[0013] (III) Beneficial Effects

[0014] This utility model provides a plastic sheet slitting and cutting device. It has the following beneficial effects:

[0015] (1) The plastic sheet on the carrier roller enters the cutting process through the conveyor roller. The motor on the fixed plate drives the threaded rod to rotate, which drives the oblique cutter on the connecting plate to move left and right under the limit of the limit rod, cutting the plastic sheet into pieces of the required width. The electric push rod on the bracket is started, which drives the straight cutter on the outer shell to move down under the limit, further cutting the sheet. This combination solves the problem that the existing device is difficult to cut sheets of different sizes quickly, realizes the rapid slicing and cutting of plastic sheets, can accurately meet different size requirements, and improves production efficiency and product adaptability.

[0016] (2) Rotate the adjusting screw, which drives the connecting sleeve to move through the threaded transmission. The connecting sleeve then pushes the positioning plate to move. During the movement of the positioning plate, the limiting rod three plays a limiting role, ensuring that the positioning plate can only move smoothly in a specific direction. Together, they solve the problem of inaccurate and unstable material positioning in the existing device. Through such coordinated operation, plastic sheets can be positioned quickly and accurately, reducing positioning deviation and greatly improving the positional accuracy of the product during the processing, thereby effectively improving product quality and ensuring the smooth progress of the production process.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] Example 1: A plastic sheet slitting and cutting device includes a base 1. Fixing plates 5 are fixedly connected to both sides of the top center of the base 1. A motor 6 is fixedly connected to the outer wall of one fixing plate 5. A threaded rod 7 is fixedly connected to the output end of the motor 6. A connecting plate 8 is threadedly connected to the outer wall of the threaded rod 7. A beveled cutter 11 is disposed below the connecting plate 8. A bracket 12 is fixedly connected to the top right side of the base 1. An electric push rod 13 is fixedly connected to the top of the bracket 12. A housing 14 is fixedly connected to the output end of the electric push rod 13. A straight cutter 15 is disposed inside the housing 14. A fixing plate 5 is fixed to the top left side of the base 1. A pair of brackets 2 are fixedly connected, and a material-carrying roller 3 is provided at the top between the two brackets 2. A conveying roller 4 is provided on the left side of the base 1. A pair of limiting rods 9 are fixedly connected between the two fixed plates 5, and the connecting plate 8 is slidably connected to the outer wall of the limiting rod 9. At the same time, the threaded rod 7 is rotatably connected between the two fixed plates 5. The oblique cutter 11 is fixedly installed inside the limiting rod 9 by screw 10. The straight cutter 15 is fixedly installed inside the outer shell 14 by screw 2 16. A pair of limiting rods 2 17 are fixedly connected to the top of the outer shell 14, and the limiting rods 2 17 are slidably connected inside the bracket 12.

[0024] The material carrier roller 3, containing the plastic sheet, is placed on the bracket 2, and the plastic sheet is fed in from one end of the conveyor roller 4. Initial slicing is performed using the bevel cutter 11 at the bottom of the connecting plate 8. Based on the specific requirements for the slicing width, the motor 6 on the outer wall of the fixing plate 5 is started. The motor 6 drives the threaded rod 7 to rotate, which in turn pushes the bevel cutter 11 on the connecting plate 8 to move left and right along the first limiting rod 9, ensuring stable movement and thus cutting the plastic sheet to the required width. Afterwards, the electric push rod 13 at the top of the bracket 12 is started. The electric push rod 13 drives the straight cutter 15 on the outer casing 14 to move downward along the second limiting rod 17, performing the final cutting of the slicing plastic sheet. The coordinated operation of all components enables rapid slicing and cutting of the plastic sheet into different sizes, greatly improving work efficiency.

[0025] Example 2: The difference between this example and Example 1 is that, in this example, both sides of the base 1 are threaded with adjusting screws 18, and each adjusting screw 18 is provided with a positioning plate 20 at the other end. The outer side of the positioning plate 20 is fixedly connected with a connecting sleeve 21, and the end of the adjusting screw 18 is rotatably connected to the connecting sleeve 21. A pair of limiting rods 19 are fixedly connected to the outer side of the positioning plate 20, and the limiting rods 19 are slidably connected inside the base 1.

[0026] Rotating the adjusting screws 18 on both sides drives the connecting sleeve 21, causing the positioning plate 20 on the connecting sleeve 21 to move inward. During the movement of the positioning plate 20, the limiting rod 19 functions to confine it within the base 1, ensuring smooth and accurate movement of the positioning plate 20. Through the coordinated operation of the adjusting screws 18, connecting sleeve 21, positioning plate 20, limiting rod 19, and base 1, plastic sheets can be positioned quickly and accurately, effectively reducing product defects caused by positioning deviations and thus improving product quality.

[0027] Working principle: The carrier roller 3 carrying the plastic sheet is placed on the bracket 2. The plastic sheet enters through one end of the conveyor roller 4 and is sliced ​​by the oblique cutter 11 at the bottom of the connecting plate 8. At this time, the motor 6 on the outer wall of the fixed plate 5 is started according to the slicing requirements. Under the action of the motor 6, the threaded rod 7 is driven to rotate. When the threaded rod 7 rotates, it will drive the oblique cutter 11 on the connecting plate 8 to adjust left and right. The motor 6 is limited by the limit rod 9 when moving to ensure more stable movement. The oblique cutter 11 will divide the plastic sheet into the required width. Then, in conjunction with the electric push rod 13 at the top of the starting bracket 12, The electric push rod 13 drives the straight cutter 15 on the outer shell 14 to move downward and cut the plastic sheet. When the outer shell 14 moves downward, it is limited by the second limiting rod 17. Through their cooperation, the plastic sheet can be quickly cut into different sizes, thereby improving work efficiency. Rotating the adjusting screws 18 on both sides causes the adjusting screws 18 to drive the positioning plate 20 on the connecting sleeve 21 to move inward. When the positioning plate 20 moves, it is limited in the base 1 by the third limiting rod 19. Through their cooperation, the plastic sheet can be quickly positioned, improving product quality.
