[0021] Please refer to Figures 1-5, the utility model provides a cutting machine for PVC sheet production, including a device body 1. On both sides of the top of the device body 1, a first vertical mounting plate 2 and a second vertical mounting plate 24 are respectively fixedly connected. At the top between the first vertical mounting plate 2 and the second vertical mounting plate 24, a connecting top plate 4 is fixedly installed. On both sides of the bottom end of the second vertical mounting plate 24, a second motor 14 is fixedly installed. The output end of the second motor 14 passes through the second vertical mounting plate 24 and is fixedly connected with a second lead screw 22. A second threaded seat 15 is threadedly connected to the middle of the second lead screw 22. The second motor 14 drives the second threaded seat 15 to rotate through the second lead screw 22. On the opposite sides of the two second threaded seats 15, a vertical connecting column 12 is fixedly connected. In the middle of the vertical connecting column 12, a mounting member 11 is fixedly connected. Between the two mounting members 11, a clamping plate 10 is fixedly connected. The vertical connecting column 12 installs the clamping plate 10 through the mounting member 11. The clamping plate 10 clamps and fixes the PVC sheet on the cutting table 3. At the bottom between the first vertical mounting plate 2 and the second vertical mounting plate 24, a second cross column 18 is fixedly connected. In the middle of the bottom end of the second threaded seat 15, a second connecting sleeve 13 is fixedly installed, and the second connecting sleeve 13 is slidably connected with the second cross column 18. The second connecting sleeve 13 and the second cross column 18 limit the second threaded seat 15, enabling the second threaded seat 15 to perform a horizontal displacement movement. On the side of the first vertical mounting plate 2 close to the second lead screw 22, a cutting table 3 is fixedly connected. The cutting table 3 is convenient for placing the PVC board for cutting, and the cutting table 3 is fixedly connected with the second vertical mounting plate 24. The cutting table 3 is located below the cutting knife 9. At both ends of the bottom end of the first vertical mounting plate 2 close to the clamping plate 10, a second rotating sleeve 26 is fixedly connected, and the second rotating sleeve 26 is rotatably connected with the second lead screw 22. The two first threaded seats 7 are on the same horizontal line. The second rotating sleeve 26 improves the stability of the second lead screw 22 during rotation.

[0022] At the top end of one side of the first vertical mounting plate 2, a first motor 5 is fixedly installed. The output end of the first motor 5 passes through the first vertical mounting plate 2 and is fixedly connected to a first lead screw 6. The first motor 5 drives the first threaded seat 7 to rotate through the first lead screw 6. The middle part of the first lead screw 6 is threadedly connected to the first threaded seat 7. In the middle of the top end of the first threaded seat 7, a first connecting sleeve 17 is fixedly connected. On one side of the top end of the first vertical mounting plate 2 close to the first lead screw 6, a first cross column 16 is fixedly connected. The first cross column 16 is fixedly connected to the second vertical mounting plate 24, and the first connecting sleeve 17 is slidably connected to the first cross column 16. The first connecting sleeve 17 and the first cross column 16 limit the position of the first threaded seat 7, enabling the first threaded seat 7 to perform a horizontal displacement. At the bottom end of the first threaded seat 7, an electric push rod 19 is fixedly installed. The output end of the electric push rod 19 is fixedly connected to a mounting table 8. In the middle of the bottom end of the mounting table 8, a connecting and strengthening column 20 is fixedly installed. At the bottom end of the connecting and strengthening column 20, a third motor 21 is fixedly installed. The electric push rod 19 drives the third motor 21 to rise or fall through the connecting and strengthening column 20. The output end of the third motor 21 is fixedly connected to a connecting shaft 23. On the side of the connecting shaft 23 away from the third motor 21, a cutting knife 9 is fixedly installed. The third motor 21 drives the cutting knife 9 to perform a cutting operation through the connecting shaft 23. On one side of the top end of the second vertical mounting plate 24 close to the clamping plate 10, a first rotating sleeve 25 is fixedly connected, and the first rotating sleeve 25 is rotatably connected to the first lead screw 6. The first rotating sleeve 25 improves the working stability of the first lead screw 6.

[0023] Working principle: For a cutting machine for PVC sheet production of the present utility model, when in use, the user can select the positions of the clamping plate 10 and the cutting knife 9 according to the size of the PVC sheet to be cut. When the PVC sheet is relatively small, the first motor 5 drives the first threaded seat 7 to rotate through the first lead screw 6. The first connecting sleeve 17 and the first cross column 16 limit the position of the first threaded seat 7, enabling the first threaded seat 7 to perform a leftward displacement. The cutting knife 9 on the first threaded seat 7 also moves leftward accordingly. The second motor 14 drives the second threaded seat 15 to rotate through the second lead screw 22. The second connecting sleeve 13 and the second cross column 18 limit the second threaded seat 15, enabling the second threaded seat 15 to perform a rightward displacement movement, thereby causing the clamping plate 10 to move rightward to clamp and fix the PVC sheet to prevent cutting deviation. After the position adjustment is completed, the electric push rod 19 drives the cutting knife 9 to descend so that the cutting knife 9 can perform a cutting operation. Among them, the first rotating sleeve 25 improves the working stability of the first lead screw 6, and the second rotating sleeve 26 improves the stability when the second lead screw 22 rotates.

[0024] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
