Description

Technical Field

[0001] This utility model belongs to the field of plastic cutting technology, specifically a plastic cutting device for plastic production. Background Technology

[0002] Plastic cutting equipment in plastic production is a specialized device used to cut and process plastic raw materials, semi-finished products, or finished products. It comes in various types and functions, utilizing high-speed rotating carbide saw blades for cutting, and is suitable for rigid plastic sheets or pipes.

[0003] In the existing technology, CN221338755U describes a cutting device for producing plastic products, including a frame. A cutting mechanism is located on the top of the frame, comprising a mounting bracket, a drive shaft, and a cutting blade. An mounting mechanism is located inside the drive shaft, including a positioning block, an L-shaped groove, a positioning hole, a threaded locking pin, a locking block, a positioning cover plate, and a locking nut. A positioning mechanism is located on the outer side of the frame, and a pushing mechanism is located at the top edge of the frame. By incorporating the cutting mechanism and mounting mechanism, and by replacing the cutting blade with a new one, the problem of blade dulling can be completely solved compared to grinding the blade, ensuring the cutting quality of the plastic products and improving the practicality of the device. The positioning mechanism and pushing mechanism work together to position and transport the plastic products, replacing manual operation and improving the automation and efficiency of the cutting operation.

[0004] Existing plastic cutting devices for plastic production require the plastic sheet to be placed and positioned in a suitable location for cutting. However, common positioning structures cannot position the plastic sheet in the center and are inconvenient for transporting the plastic sheet. Therefore, a new plastic cutting device for plastic production is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a plastic cutting device for plastic production.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A plastic cutting device for plastic production, comprising a worktable; a fixed frame is fixedly connected to the top of the worktable; a sliding rail is fixedly connected to the top of the fixed frame; a servo motor is mounted on the side of the sliding rail; a double-threaded screw is fixedly connected to the output end of the servo motor; the double-threaded screw is rotatably connected to the inner wall of the sliding rail; a sliding block is threadedly connected to the outer wall of the double-threaded screw; the sliding block is slidably connected to the inner wall of the sliding rail; a clamping plate is fixedly connected to the bottom of the sliding block; and a roller is rotatably connected to the bottom of the clamping plate.

[0007] Preferably, a mounting bracket is fixedly connected to the top of the workbench; a hydraulic rod is installed on the inner surface of the mounting bracket.

[0008] Preferably, the output end of the hydraulic rod is fixedly connected to a fixing plate; the bottom of the fixing plate is equipped with the cutting blade body.

[0009] Preferably, fixing blocks are fixedly connected to both sides of the fixing plate; an external rod is fixedly connected to the inner surface of the fixing block.

[0010] Preferably, a telescopic rod is slidably connected to the inner surface of the external rod; a pressing rod is fixedly connected to the bottom of the telescopic rod.

[0011] Preferably, a support block is fixedly connected to the bottom of the pressing rod; a spring is fixedly connected to the pressing rod via a fixing block.

[0012] Preferably, a cutting plate is fixedly connected to the top of the workbench; and a device base is fixedly connected to the bottom of the workbench.

[0013] The beneficial effects of this utility model are: This utility model provides a plastic cutting device for plastic production. After the double-threaded screw is driven to rotate by a servo motor, the sliding blocks move closer together and push the plastic plate to the middle of the worktable. At the same time, the rollers can also ensure the normal pushing of the plastic plate, thereby achieving the function of assisting in positioning the plastic plate and facilitating the cutting of the plastic plate.

[0014] This utility model provides a plastic cutting device for plastic production. By setting a pressing rod and a foot block, the pressing rod can slide inside the fixed block. This allows the foot block to limit the movement of the plastic plate after contacting it, while also ensuring the normal descent of the cutting blade. Attached Figure Description

[0020] Please see Figures 1-4 This utility model provides a plastic cutting device for plastic production, including a workbench 2; a fixed frame 4 is fixedly connected to the top of the workbench 2; a sliding rail 5 is fixedly connected to the top of the fixed frame 4; a servo motor 9 is installed on the side of the sliding rail 5; a double-threaded screw 10 is fixedly connected to the output end of the servo motor 9; the double-threaded screw 10 is rotatably connected to the inner wall of the sliding rail 5; a sliding block 11 is threadedly connected to the outer wall of the double-threaded screw 10; the sliding block 11 is slidably connected to the inner wall of the sliding rail 5; a clamping plate 12 is fixedly connected to the bottom of the sliding block 11; a roller 13 is rotatably connected to the bottom of the clamping plate 12; during operation, when a plastic sheet is placed on the top of the workbench 2, the servo motor 9 can be started to rotate along the double-threaded screw 10 with a mirrored thread in the middle, driving the sliding block 11 to slide inside the sliding rail 5 and move closer to each other, synchronously driving the clamping plate 12 and the roller 13 to be limited to both sides of the plastic sheet, thereby achieving the function of assisting the plastic sheet to move to the middle position of the workbench 2.

[0021] Furthermore, such as Figure 2 and Figure 4As shown, a mounting bracket 6 is fixedly connected to the top of the workbench 2; a hydraulic rod 7 is installed on the inner wall of the mounting bracket 6; a fixing plate 8 is fixedly connected to the output end of the hydraulic rod 7; a cutting blade body 14 is installed at the bottom of the fixing plate 8; fixing blocks 15 are fixedly connected to both sides of the fixing plate 8; an external rod 16 is fixedly connected to the inner wall of the fixing block 15; a telescopic rod 17 is slidably connected to the inner wall of the external rod 16; a pressing rod 19 is fixedly connected to the bottom of the telescopic rod 17; a foot block 20 is fixedly connected to the bottom of the pressing rod 19; a spring 18 is fixedly connected to the pressing rod 19 through the fixing block 15; a cutting plate 3 is fixedly connected to the top of the workbench 2; and a device base 1 is fixedly connected to the bottom of the workbench 2. During operation, after activating the hydraulic rod 7, the cutting blade body 14 and the support block 20 can be lowered as a whole. At this time, the support block 20 will first contact the plastic plate, causing the pressing rod 19 to slide inside the fixed block 15. At this time, the external rod 16 and the spring 18 are in a compressed state. Simultaneously, the compressed spring 18 can push the support block 20 to descend and abut against the top of the plastic plate for limiting.

[0022] Working principle: When the plastic plate is placed on top of the workbench 2, the servo motor 9 can be started to rotate. The double-threaded screw 10 with a mirrored thread in the middle part rotates and drives the sliding block 11 to slide inside the sliding track 5 and move closer to each other. Simultaneously, the clamping plate 12 and the roller 13 are limited to both sides of the plastic plate, thereby assisting the plastic plate to move to the middle position of the workbench 2. After the hydraulic rod 7 is started, the cutting blade body 14 and the support block 20 can be lowered as a whole. At this time, the support block 20 will first contact the plastic plate, so that the pressing rod 19 slides inside the fixed block 15. At this time, the external rod 16 and the spring 18 are in a compressed state. At the same time, the compressed spring 18 can push the support block 20 to fall and abut against the top of the plastic plate for limitation.
