Abstract
Description
Technical Field
[0001] This utility model relates to a PP sheet cutting device, belonging to the field of PP sheet production technology. Background Technology
[0002] The production process of PP sheets typically employs extrusion molding technology. First, polypropylene (PP) resin granules are heated and melted. Then, the molten polypropylene material is extruded into thin sheets through an extruder. The extruded PP sheets are rapidly cooled and shaped by cooling rollers or a water cooling system to ensure the flatness and uniform thickness of the sheets. After cooling, the PP sheets can be sheared, wound, or further processed as needed. The entire production process requires strict control of temperature, pressure, and speed to ensure stable sheet quality and good mechanical properties, chemical resistance, and weather resistance.
[0003] In the production of PP sheets, cutting equipment is needed to shear the sheets. Since most blades can only operate in fixed directions and angles, they often cannot flexibly adapt to the needs of different shapes and specifications during the cutting process. When dealing with irregular or complex PP sheets, multiple adjustments or repositionings are often required, which wastes time and increases the complexity of the operation. In addition, due to the limitation of the cutting angle, the edges of the sheet may not be flat, affecting the appearance and precision of the product. Especially in situations requiring high precision, it is difficult to meet the expected quality standards. More importantly, the cutting speed may not be effectively increased during the production process, affecting the overall production efficiency.
[0004] Therefore, a PP sheet cutting device is proposed. Utility Model Content
[0005] In view of this, the present invention provides a PP sheet cutting device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.
[0006] The technical solution of this utility model is implemented as follows: a PP sheet cutting device includes a base plate and an adjustment component. A base box is fixedly connected to the top of the base plate. Electric telescopic rods are fixedly connected to all four sides of the top of the base box. A top plate is fixedly connected to the top of the electric telescopic rods. A fixing box is fixedly connected to the top of the top plate.
[0007] The adjustment assembly includes a screw, which is movably connected to the inner cavity of the fixed box via a bearing. A threaded sleeve is threaded onto the surface of the screw, and a connecting rod is fixedly connected to the bottom of the threaded sleeve. A fixed frame is fixedly connected to the bottom of the connecting rod, and a stepper motor is fixedly connected to the inner side of the fixed frame. A turntable is fixedly connected to the output end of the stepper motor, and a slide is fixedly connected to the bottom of the turntable. A slider is slidably connected to the surface of the slide, and a laser cutting module is provided at the bottom of the slider.
[0008] More preferably, a servo motor for driving the screw to rotate is fixedly connected to the right side of the fixing box, and the output end of the servo motor is fixedly connected to the right end of the screw.
[0009] More preferably, a groove is provided on the top of the inner wall of the fixing box, and a slider is fixedly connected to the top of the screw sleeve, with the top of the slider slidably connected to the inner cavity of the groove.
[0010] More preferably, the bottom of the fixing box and the inner surface of the top plate are both provided with through grooves, and the bottom of the connecting rod passes through the inner cavity of the through groove and extends to the bottom of the top plate.
[0011] More preferably, guide rods are fixedly connected to the front and back sides of the bottom of the top plate, and limit rings are fixedly connected to the front and back sides of the fixing frame, with the limit rings slidably connected to the surface of the guide rods.

[0013] More preferably, the output end of the cylinder is fixedly connected to a clamp, and the top and bottom of the inner side of the clamp are both bonded with elastic anti-slip pads.
[0014] The present invention has the following advantages due to the adoption of the above technical solution:

It can effectively improve the stability of the fixing frame during horizontal movement by setting a guide rod and a limiting ring. It can adjust the height of the top plate by setting an electric telescopic rod, thereby adjusting the cutting height. By extending the output end of the cylinder inward and driving the clamp to move inward, it can limit the workpieces of different specifications.

[0028] The output of the servo motor 601 drives the screw 602 to rotate. During the rotation, the screw 602 uses the thread to drive the screw sleeve 603 to move horizontally. The screw sleeve 603 drives the stepper motor 606 to move horizontally through the transmission of the connecting rod 604 and the fixing frame 605. The stepper motor 606 drives the laser cutting module to move horizontally through the slider 609, which can adjust the cutting position once.
