[0019] Example: Figure 1-4 As shown, the utility model provides a cutting device for the production of plastic sheets, including a base plate 1, a fixed plate 3 is fixedly connected to one side of the top of the base plate 1, a cylinder 7 is fixedly connected to the top of the base plate 1, and a rotating rod 8 is rotatably connected to the output end of the cylinder 7, so that when the cylinder 7 is started, one end of the rotating rod 8 can be driven to rise and the other end can be driven to fall at the same time, and the other end of the rotating rod 8 can cooperate with the fixed block 13 to fix the plastic sheet.
[0020] The outer surface of the rotating rod 8 is rotatably connected to a support frame 14, and the support frame 14 and the bottom end of the fixed block 13 are fixedly connected to the top of the bottom plate 1, which can make the device more stable during operation. The outer surface of the rotating rod 8 away from the cylinder 7 is rotatably connected to a pressure plate 34, and one end of the support frame 14 is fixedly connected to a fixed block 13. The fixed block 13 is located directly below the pressure plate 34, so that the rotating rod 8 can fix the pressure plate 34 when it drives the pressure plate 34 to move downward. Both sides of the top of the fixed block 13 are fixedly connected to the limiting plates 31.
[0021] A slide groove 32 is provided at the opposite end of the two limit plates 31, and sliders 33 used in conjunction with the slide groove 32 are fixedly connected to both ends of the pressure plate 34. The existence of the slider 33 and the slide groove 32 allows the pressure plate 34 to drop vertically when the rotating rod 8 drives the pressure plate 34 to drop, thereby facilitating the fixing of the plastic sheet.
[0022] The fixed plate 3 is fixedly connected to the end opposite to the fixed block 13 with a long rod 2. A support block 15 is slidably provided on the outer surface of the long rod 2. Two limit bars 16 are fixedly connected to the two sides of the top of the support block 15. The support block 15, the fixed block 13 and the support frame 14 are all distributed in parallel. The two limit bars 16 can effectively limit the plastic sheet in the middle. One end of the support block 15 is fixedly connected to a connecting plate 28. Through the connection of the connecting plate 28, the support block 15 can be driven to move when the moving frame is moved. One end of the connecting plate 28 is fixedly connected to a cutting mechanism 5.
[0023] The cutting mechanism 5 includes a moving block 17, the bottom end of which is rotatably connected to four rollers 21, the outer surfaces of the four rollers 21 are fitted with the top of the bottom plate 1, one end of the moving block 17 is fixedly connected to a handle 11, and the rollers 21 are driven to rotate by moving the handle 11, so that the moving block 17 can be driven to move, which is convenient for cutting the plastic sheet. One end of the moving block 17 is fixedly connected to a connecting plate 28, one end of the moving block 17 is provided with a rectangular groove 18, and a rack 24 is slidably provided on the inner wall of one side of the rectangular groove 18, and one end of the rack 24 is fixedly connected to a convex block 22, and a convex groove 12 used by the convex block 22 is provided on the inner wall of one side of the rectangular groove 18, which can make the rack 24 move more smoothly and also limit the rack 24 to prevent it from falling off. Two limit blocks 23 are fixedly connected to the outer surface of the rack 24, and the two limit blocks 23 are mirror-imaged, so that the rack 24 can be prevented from moving out of the motion trajectory when it moves.
[0024] The inner surface of the rack 24 is rotatably connected with a cutting knife 26, and one end of the rack 24 is meshed with a gear 27, which can be rotated to drive the rack 24 to move, and at the same time can drive the cutting plate at one end to move to cut the plastic sheet.
[0025] The two ends of the gear 27 are rotatably connected to the upper and lower inner walls of the rectangular groove 18. A motor 25 is provided at the top of the moving block 17. The output end of the motor 25 passes through the moving block 17 and is fixedly connected to one end of the gear 27. The top of the bottom plate 1 is fixedly connected to a vertical plate 6. The end of the vertical plate 6 opposite to the fixed plate 3 is commonly fixedly connected to a sliding rod 4. The outer surface of the sliding rod 4 is slidably connected to the inner surface of the moving block 17.
[0026] Working principle: When it is necessary to cut the plastic sheet, first fix it, place the plastic sheet to be cut on the top of the support block 15 and the fixed block 13, then turn on the cylinder 7, which will drive one end of the rotating rod 8 to rise, and under the action of the support block 15, the other end of the rotating rod 8 can be lowered, and the other end of the rotating rod 8 drives the pressing plate 34 to descend, and at the same time cooperate with the fixed block 13 to fix the plastic sheet, and then cut it;
[0027] When it is necessary to cut plastic sheets, first turn on the motor 25. The motor 25 can drive the gear 27 to rotate, the gear 27 drives the rack 24 to move, and the rack 24 drives the cutting plate to move, so that the plastic sheets can be cut. When it is necessary to cut plastic sheets of different sizes, under the action of the four rollers 21, the handle 11 can drive the moving block 17 to move, and the moving block 17 can drive the supporting block 15 to move. When it moves to the appropriate position, turn on the motor 25 again to cut the plastic sheets.
[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
