As my country's economy has achieved sustained and stable growth, industries such as home appliances, automobiles, mobile phones, PCs, and medical devices have also achieved rapid development thanks to a favorable external environment.

[0003] Plastic is made of carbon compounds. Plastic is processed in a whole piece. Therefore, a cutting device is needed to cut the plastic after processing. A positioning mechanism is needed to position the plastic to prevent the plastic from shifting during cutting, which causes the plastic cutting to shift.

[0004] After searching, the patent announcement number CN211541438U discloses a positioning mechanism for a cutting device for plastic processing, including a body, the four corners of the top of the body are fixedly connected to a base, the top of the base is movably connected to a turntable, the opposite sides of the left and right turntables are fixedly connected to a connecting plate, the bottoms of the opposite sides of the left and right connecting plates are fixedly connected to a backing plate, the inside of the turntable is movably connected to a snap mechanism, and the top of the body is provided with plastic used in conjunction with the backing plate. The utility model solves the problem that the existing cutting device needs a positioning mechanism to position the plastic when cutting plastic, and prevents the plastic from shifting during cutting, which causes the plastic cutting to shift, by providing a body, a base, a turntable, a connecting plate, a backing plate, a snap mechanism, a through hole, a connecting block, a card block, a groove, an anti-slip pad, a handle, a protrusion, a card slot and a plastic for coordinated use.

[0005] When existing plastic product cutting equipment performs cutting operations on plastic sheet products, the plastic sheet products are generally limited and moved manually for cutting. The above cutting operation has poor stability and is prone to cause deviation of the plastic sheet products during cutting, which reduces the quality of the cutting of the plastic sheet products and has low safety. Therefore, we propose a positioning mechanism for plastic product cutting processing to solve the existing problems. Utility Model Content

[0006] The purpose of the utility model is to provide a positioning mechanism for cutting and processing plastic products to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, sliders are installed on both sides of the lower surface of the movable plate, the bottom ends of the sliders are installed on slide rails, and the sliders are slidably connected to the slide rails, and the slide rails are installed on both sides of the upper surface of the workbench.

[0009] Preferably, support columns are installed at four corners of the lower surface of the workbench, and the bottom ends of the support columns are installed on the upper surface of the base.

[0010] Preferably, the top of the cutting blade passes through the rectangular slot and extends above the workbench, and the rectangular slot is opened on the surface of the workbench.

[0011] Preferably, a driven pulley is installed on the outer wall of the other end of the rotating shaft, and the driven pulley is connected to the driving pulley through a transmission belt.

[0012] Preferably, the driving pulley is mounted on the output shaft of the reduction motor, and the reduction motor is mounted on the upper surface of the base.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is provided with a series of coordinated structures. When the staff needs to cut the plastic sheet product, the staff places both ends of the plastic sheet product at the inner bottom ends of the two U-shaped clamps, and then starts the second hydraulic telescopic rod. The start of the second hydraulic telescopic rod will drive the U-shaped clamp to move in the X-axis direction. The movement of the U-shaped clamp in the X-axis direction can clamp and fix the plastic sheet product in the X-axis direction. The staff starts the electric push rod. The extension of the electric push rod will drive the fixed clamp to move in the Y-axis direction. The staff makes the fixed clamp clamp and fix the plastic sheet product in the Y-axis direction. When the plastic sheet product is fixed and clamped, the staff starts the reduction motor and the first hydraulic telescopic rod. The start of the reduction motor will indirectly drive the cutting blade to rotate. The first hydraulic telescopic rod When the retraction rod is started, the movable plate will move in the Z-axis direction. The movement of the movable plate in the Z-axis direction can indirectly drive the plastic sheet product fixed and clamped on the utility model to move in the Z-axis direction. When the plastic sheet product moves in the Z-axis direction and moves to the cutting blade, the cutting blade cuts the plastic sheet product. Therefore, it can be seen from the above that when the utility model performs a cutting operation on the plastic sheet product, it is convenient for the staff to clamp and fix the plastic sheet product, and there is no need to manually move the plastic sheet product for cutting operation, which reduces the labor intensity and avoids the offset of the plastic sheet product during cutting, improves the stability and accuracy of the plastic sheet product during cutting, and also improves the quality of cutting the plastic sheet product, improves the safety, and also facilitates the staff to cut plastic sheet products of different sizes, and has strong practicality.

[0024] The working principle of the positioning mechanism for cutting and processing plastic products based on the first embodiment is: when the staff needs to cut the plastic sheet product, the staff places both ends of the plastic sheet product at the inner bottom ends of the two U-shaped clamps 6, and then starts the second hydraulic telescopic rod 5. The start of the second hydraulic telescopic rod 5 will drive the U-shaped clamp 6 to move in the X-axis direction. The U-shaped clamp 6 moves in the X-axis direction so that the plastic sheet product can be clamped and fixed in the X-axis direction. The staff starts the electric push rod 7. The extension of the electric push rod 7 will drive the fixed clamp 3 to move in the Y-axis direction. The staff makes the fixed clamp 3 clamp and fix the plastic sheet product in the Y-axis direction. When the plastic sheet product is fixed and clamped, the staff starts the reduction motor 12 and the first hydraulic telescopic rod 2. The start of the reduction motor 12 will indirectly drive the cutting blade 9 to rotate. Pressing the telescopic rod 2 to start will drive the movable plate 4 to move in the Z-axis direction. The movement of the movable plate 4 in the Z-axis direction can indirectly drive the plastic sheet product fixed and clamped on the utility model to move in the Z-axis direction. When the plastic sheet product moves in the Z-axis direction and moves to the cutting blade 9, the cutting blade 9 cuts the plastic sheet product. Therefore, it can be seen from the above that when the utility model performs a cutting operation on the plastic sheet product, it is convenient for the staff to clamp and fix the plastic sheet product, and there is no need to manually move the plastic sheet product for cutting operation, which reduces the labor intensity, avoids the occurrence of offset when cutting the plastic sheet product, improves the stability and accuracy of the plastic sheet product cutting, and also improves the quality of cutting the plastic sheet product, improves the safety, and also facilitates the staff to cut plastic sheet products of different sizes.
