[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Depend on Figures 1 to 3 The present invention includes a base 1, a groove 2 on the top of the base 1, and support blocks 3 fixedly installed at equal distances between the tops of the two sides of the groove 2. An adjustable mounting plate 4 is provided inside the groove 2. N-shaped support blocks 5 are fixedly installed at equal distances on the top of the mounting plate 4. The N-shaped support blocks 5 and the support blocks 3 are alternately arranged. Ball bearings 6, which facilitate the orientation adjustment of the plastic sheet, are installed at equal distances on the top of the N-shaped support blocks 5. An N-shaped frame 7 is fixedly installed in the middle of the top of the base 1. A horizontally movable convex block 8 is installed on the top of the inner side of the N-shaped frame 7. A fixing frame 9 is installed at one end of the bottom of the convex block 8. An electric cutter 10 is installed at the bottom of the fixing frame 9. The cutting wheel of the electric cutter 10 is located between two adjacent support blocks 3. A chip removal groove 201 is provided at the bottom of the groove 2, located directly below the cutting wheel of the electric cutter 10.

[0016] A positioning and fixing plate 11 is installed on the inner side of the n-shaped frame 7. T-shaped pins 12 are equidistantly inserted into one side of the middle part of the n-shaped frame 7. The bottom of each T-shaped pin 12 is fixedly connected to the top of the positioning and fixing plate 11. A return spring 13 is sleeved on the upper part of each T-shaped pin 12. The two ends of the return spring 13 are fixedly connected to the T-shaped pin 12 and the n-shaped frame 7 respectively. A motor 14 for adjusting the convex block 8 is installed at one end of the n-shaped frame 7.

[0017] Sleeves 15 are fixedly installed at equal intervals on both sides of the bottom of the groove 2. Inverted T-shaped rods 16 are movably inserted into the inside of each sleeve 15. The top of each inverted T-shaped rod 16 is fixedly connected to the bottom of the mounting plate 4. Inclined pressure blocks 17 are fixedly installed at equal intervals on the bottom of the mounting plate 4. A limit frame 18 is fixedly installed in the middle of the bottom of the groove 2. A threaded rod 19 is rotatably connected inside the limit frame 18. Inclined extrusion blocks 20 that match and align with the inclined pressure blocks 17 are threaded at equal intervals on the surface of the threaded rod 19. One end of the threaded rod 19 extends to one end of the base 1 and is fixedly connected to a rotating wheel 21, thereby effectively moving the plastic sheet down and placing it on the support block 3.

[0018] When in use, place the plastic sheet on top of the n-shaped support block 5, and then adjust the position of the plastic sheet by rolling the ball 6 so that the cutting position of the plastic sheet is aligned with the cutting wheel of the electric cutting machine 10.

[0019] Then, rotating the wheel 21 causes the threaded rod 19 to rotate. The rotation of the threaded rod 19 causes all the inclined extrusion blocks 20 to move inside the limit frame 18. The movement of the inclined extrusion blocks 20 will move them away from the inclined surface of the inclined pressure block 17. At this time, the mounting plate 4 is inserted into the sleeve 15 through the inverted T-shaped rod 16, which drives the mounting plate 4 to move down. The downward movement of the mounting plate 4 will drive the n-shaped support block 5 and the plastic sheet to move down. Finally, the plastic sheet is placed between the top of the support block 3 and the cutting position of the plastic sheet is aligned with the cutting wheel of the electric cutting machine 10.

[0020] A horizontal groove 22 is provided on the top of the inner side of the n-shaped frame 7. A threaded shaft 23 connected to the output end of the motor 14 is rotatably installed inside the horizontal groove 22. A convex block 8 is threadedly connected to the surface of the threaded shaft 23. An isosceles trapezoidal block 24 is installed at the other end of the bottom of the convex block 8. A lower pressure plate 25 aligned with the isosceles trapezoidal block 24 is fixedly installed on the top of the positioning and fixing plate 11. An extrusion slope 26 matching the slope of the isosceles trapezoidal block 24 is provided on the upper part of both ends of the lower pressure plate 25, so that positioning and fixing operations can be performed before cutting.

[0021] When the plastic sheet is positioned between the top of the support blocks 3, the threaded shaft 23 is rotated by starting the motor 14. The rotation of the threaded shaft 23 causes the convex block 8 to move. The movement of the convex block 8 drives the isosceles trapezoidal block 24 and the electric cutter 10 to move. The movement of the isosceles trapezoidal block 24, through the pressing inclined surface 26, will press the lower pressure plate 25 downward. The downward movement of the lower pressure plate 25 will drive the positioning and fixing plate 11 to move downward, so that the positioning and fixing plate 11 positions and fixes the plastic sheet at the top of the support block 3. The downward movement of the positioning and fixing plate 11 will drive the T-pin 12 to move downward and compress the return spring 13.

[0022] Finally, the positioning and fixing plate 11 positions and fixes the plastic sheet, while the moving and started electric cutting machine 10 will cut the plastic sheet. After the cutting is completed, the isosceles trapezoidal block 24 will separate from the lower pressure plate 25, and the elastic restoring force of the return spring 13 will cause the positioning and fixing plate 11 to move upward and separate from the plastic sheet.

[0023] This plastic sheet cutting auxiliary positioning device has a cutting position adjustment structure and a cutting positioning fixing structure. The cutting position adjustment structure can adjust the cutting position of the plastic sheet, while the cutting positioning fixing structure can fix it during cutting to ensure the stability of the cutting, thereby effectively ensuring the cutting quality and improving the convenience of cutting.

[0024] This cutting auxiliary positioning device has a simple structural design, is convenient and easy to use and operate, and is stable and reliable. Its performance can meet the needs of plastic sheet cutting and processing.
