[0031] like Figure 1-4As shown, the present invention proposes a plastic sheet cutting device, including a base plate 24, a support frame 2, a first moving component and a cutting machine 1. The support frame 2 is located above the base plate 24 and connected to both sides of the base plate 24. The inner top wall of the support frame 2 is connected to the cutting machine 1 through the first moving component.

[0032] It also includes a second placement plate 14 and a first placement plate 13, which are located on the upper surface of the base plate 24. A pushing component is installed on the side of the second placement plate 14, and a slot 12 is passed through the middle of the first placement plate 13. A second moving component is provided inside the base plate 24, and the moving end of the second moving component is connected to the first push plate 11 through the slot 12.

[0033] A limit assembly is installed on the outer side wall of the support frame 2, near the first push plate 11;

[0034] Support plates 18 are installed on both sides of the outer end face of the base plate 24, and symmetrically distributed guide mechanisms are installed on the upper end face of both support plates 18.

[0035] In this invention, during use, the position of the pushing component's abutting end is first adjusted to determine the position where the plastic sheet needs to be cut. Then, the plastic sheet is placed on the second placement plate 14 and the first placement plate 13, with the pushing component's abutting end contacting the second push plate 15. At this time, the guiding mechanisms on both sides are activated to initially guide the plastic sheet. Simultaneously, the limiting end of the limiting component contacts the plastic sheet, allowing it to clamp the plastic sheet, effectively limiting the displacement of the plastic sheet during the cutting process and ensuring that the sheet is in the accurate starting position for processing.

[0036] According to the cutting requirements, the second moving component is activated, thereby moving the first push plate 11 to a position in contact with the plastic sheet, in preparation for the subsequent pushing of the plastic sheet;

[0037] Cutting operation: Start the first moving component, thereby driving the cutting machine 1 to move along the gap between the second placement plate 14 and the first placement plate 13. Since the cutting end of the bottom of the cutting machine 1 is higher than the upper surface of the bottom plate 24 and lower than the upper surface of the second placement plate 14, it can effectively cut the plastic sheet in the accurate position. After cutting, the cut plastic sheet is removed. The plastic sheet can be moved by the movement of the first push plate 11, so that the side of the plastic sheet to be cut comes into contact with the second push plate 15. Then the plastic sheet can be cut by the cutting machine 1.

[0038] In an optional embodiment, the first moving component includes a slide rail 25 and an electric slider 26. The slide rail 25 is installed on the inner top wall of the support frame 2, and one end of the electric slider 26 is slidably connected to the slide groove of the slide rail 25. One end of the electric slider 26 is connected to the cutting machine 1, thereby driving the cutting machine 1 to move.

[0039] It should be noted that when it is necessary to move the cutting machine 1, the electric slider 26 is activated. The electric slider 26 can move in the groove of the slide rail 25, so that it can move the cutting machine 1 accordingly, thereby cutting the plastic sheet.

[0040] In an optional embodiment, the pushing assembly includes a third electric push rod 17, a third mounting base 16, and a second push plate 15. The third mounting base 16 is mounted on the side of the second placement plate 14. The third electric push rod 17 is mounted on the third mounting base 16 with its telescopic shaft facing the first push plate 11. The second push plate 15 is mounted on the telescopic shaft of the third electric push rod 17 and is used to push the plastic sheet to move, thereby controlling the size of the cut plastic sheet.

[0041] It should be noted that the third mounting base 16 can be used to install and fix the third electric push rod 17; and by extending and retracting the third electric push rod 17, the second push plate 15 can be moved, thereby controlling the size of the cut plastic sheet.

[0042] In an optional embodiment, the second moving component includes a drive motor 20, a moving block 19, a groove 23, and a threaded rod 22. The groove 23 is formed at the upper end of the base plate 24. The drive motor 20 is mounted on the outer side wall of the base plate 24. One end of the threaded rod 22 is rotatably connected to one end of the inner wall of the groove 23. The other end of the threaded rod 22 passes through the outer end face of the base plate 24 and is coaxially connected to the output shaft of the drive motor 20 through a coupling. The moving block 19 is threaded onto the outer surface of the threaded rod 22. The upper end of the moving block 19 is connected to the first push plate 11 through a slot 12, which can drive the first push plate 11 to move.

[0043] It should be noted that when the drive motor 20 is started, the drive motor 20 can drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, it can drive the moving block 19 to move accordingly. The moving block 19 can move inside the slot 12, thereby driving the first push plate 11 to move accordingly, so that it can push the plastic sheet to move.

[0044] In an optional embodiment, the guiding mechanism includes a second electric push rod 5, a first mounting base 6, a guide plate 9, guide members, and multiple guide wheels 10. The middle part of the upper end of the support plate 18 is connected to the second electric push rod 5. The second electric push rod 5 is installed in the middle of the first mounting base 6. The first mounting base 6 can stabilize the second electric push rod 5. The telescopic shaft of the second electric push rod 5 is connected to the guide plate 9 that cooperates with it. There are multiple guide members, and their telescopic ends are connected to the guide plate 9. Multiple guide wheels 10 are evenly distributed and installed on the side of the guide plate 9 near the first placement plate 13. The guide member includes a guide rod 7 and a second mounting base 8. The guide rod 7 is installed on the support plate 18 and inside the second mounting base 8. The telescopic end of the guide rod 7 is connected to the guide plate 9. Through the guide rod 7, when the second electric push rod 5 drives the guide plate 9 connected to it to move, the stability of the movement of the guide plate 9 can be ensured.

[0045] It should be noted that when using the equipment, the plastic sheet is first placed on the first placement plate 13, and then the second electric push rods 5 on both sides are activated. The mounting plates 4 on both sides can drive the guide plates 9 connected to them to move relative to each other, so that the multiple guide wheels 10 on both sides can contact the sides of the plastic sheet to form a physical constraint, restricting the plastic sheet from lateral displacement during movement and making it move smoothly along the preset direction.

[0046] In an optional embodiment, the limiting assembly includes a first electric push rod 3, a mounting plate 4, and a guide roller 21. The mounting plate 4 is mounted on the side of the support frame 2, the first electric push rod 3 is mounted on the upper surface of the mounting plate 4, and the telescopic shaft of the mounting plate 4 passes through the mounting plate 4 and is connected to the guide roller 21.

[0047] It should be noted that when the plastic sheet is placed on the first placement plate 13, the position of the plastic sheet to be cut is first adjusted so that the side of the plastic sheet to be cut abuts against the second push plate 15. Then, the first electric push rod 3 is activated to drive the guide roller 21 to descend and contact the sheet to be cut. After the plastic sheet is cut, the plastic sheet is moved by the movement of the first push plate 11, and the guide roller 21 will rotate accordingly. At this time, the guide roller 21 and the second push plate 15 form a clamping force on the sheet, which can effectively limit the displacement of the plastic sheet during the cutting process. The plastic sheet will be subjected to the force of the cutting machine 1 during cutting. If there is no stable positioning, the sheet is prone to shaking or displacement, resulting in inaccurate cutting dimensions and uneven cuts. Therefore, it is necessary to improve cutting accuracy and ensure cutting quality.

[0048] In an optional embodiment, the upper surfaces of the second placement plate 14 and the first placement plate 13 are on the same plane, and their upper surfaces are both smooth to facilitate the placement and movement of the plastic sheet. The cutting trajectory of the cutting machine 1 is located between the gap between the second placement plate 14 and the first placement plate 13, and the bottom cutting end of the cutting machine 1 is higher than the upper surface of the base plate 24 and lower than the upper surface of the second placement plate 14 to ensure effective cutting of the plastic sheet.

[0049] Working principle:

[0050] First, the third electric push rod 17 is activated, which moves the second push plate 15 to determine the position where the plastic sheet needs to be cut. Then, the plastic sheet is placed on the second placement plate 14 and the first placement plate 13, with its cutting end in contact with the second push plate 15. At this time, the second electric push rod 5 in the guide mechanism is activated, and the telescopic shaft of the second electric push rod 5 moves, which drives the guide plate 9 to move through the guide rod 7. This causes the multiple equally spaced guide wheels 10 on the guide plate 9 to contact the plastic sheet, providing initial guidance for the sheet. At the same time, the first electric push rod 3 in the limiting assembly is activated, and its telescopic shaft passes through the mounting plate 4 to push the guide roller 21 to contact the plastic sheet, which can clamp the plastic sheet and effectively limit the displacement of the plastic sheet during the cutting process, ensuring that the sheet is in the accurate starting position for processing.

[0051] According to the cutting requirements, the drive motor 20 in the second moving component is started. The output shaft of the drive motor 20 drives the threaded rod 22 to rotate through the coupling. Since the moving block 19 is threaded on the outer surface of the threaded rod 22, the rotation of the threaded rod 22 causes the moving block 19 to move linearly on the threaded rod 22. Then, through the slot 12 in the middle of the first placement plate 13, the first push plate 11 is moved to the position that contacts the plastic sheet, preparing for the subsequent pushing of the plastic sheet.

[0052] Cutting operation: Activate the electric slider 26 in the first moving assembly. The electric slider 26 can move on the slide rail 25, driving the cutter 1 to move along the gap between the second placement plate 14 and the first placement plate 13. Since the bottom cutting end of the cutter 1 is higher than the upper surface of the base plate 24 and lower than the upper surface of the second placement plate 14, it can effectively cut the plastic sheet in the accurate position. After cutting, remove the cut plastic sheet. The movement of the first push plate 11 can drive the plastic sheet to move accordingly, so that the side of the plastic sheet to be cut comes into contact with the second push plate 15. Then the cutter 1 can cut the plastic sheet.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
