Description

Technical Field

[0001] The present invention belongs to the technical field of polytetrafluoroethylene processing, and particularly relates to a laser cutting device for producing polytetrafluoroethylene products. Background Technique

[0002] Polytetrafluoroethylene (PTFE) is widely used in high-precision products such as seals and gaskets due to its excellent chemical stability, high temperature resistance, and low friction coefficient. As a non-contact processing method, laser cutting vaporizes materials locally through high-energy laser beams, with advantages such as high processing accuracy and smooth burr-free cuts, especially suitable for precision processing of thin PTFE films, tapes, and other thin products with a thickness ≤ 2 mm. However, when applied to PTFE plates with a thickness ≥ 5 mm, the existing laser cutting technology faces significant challenges: 1. The thermal conductivity of PTFE is low (about 0.25 W / m·K). When laser cutting thick plates, heat easily accumulates in the cutting area, and it is necessary to significantly increase the laser power and extend the action time (for every 1 mm increase in thickness, the cutting time is extended by 15% - 20%), resulting in edge carbonization and increased burrs, seriously affecting the qualified rate of finished products; 2. PTFE decomposes to produce harmful gases such as hydrogen fluoride (HF) and tetrafluoroethylene (TFE) at high temperatures (>400°C). Most existing equipment relies on an external exhaust system, but the gas collection efficiency is insufficient, and the residual harmful gases pose a threat to the operating environment and personnel health; 3. Existing technologies attempt to reduce the cutting resistance through preheating or use a water cooling system for cooling, but the heating and cooling processes are separated, making it difficult to coordinately control the temperature of the cutting area, resulting in thermal stress concentration and exacerbating material deformation or cracking; Therefore, it is necessary to design a laser cutting device for producing polytetrafluoroethylene products to solve the above problems.

A collection linear guide 66 is fixedly installed on the upper side of the filter collection box 62.

[0023] For the cleaning mechanism 6 adopting the above technical solution, during use, the filtering and collecting box 62 and the collecting linear guide 66 are conveniently moved following the adjusting mechanism 2 through the installation of the installation cross beam 61, so that the collecting linear guide 66 and the air extraction head 65 can conveniently extract air from the cutting area of the laser cutting main body 7, and the harmful gases and residues generated by cutting the polytetrafluoroethylene products can be collected and cleaned, avoiding pollution to the working environment.

[0024] Further, reference can be made to Figures 1 to 8, the adjusting mechanism 2 includes an adjusting moving seat 21. An elevating hydraulic cylinder 22 is fixedly installed inside the adjusting moving seat 21. A piston rod of the elevating hydraulic cylinder 22 is fixedly installed with an elevating column 23. The elevating column 23 is slidably installed inside the adjusting moving seat 21. The upper end of the elevating column 23 is fixedly installed with a cutting linear guide 24 through bolts. The heat exchange mechanism 3 is installed on the upper side of the cutting linear guide 24. The cutting mounting seat 8 is slidably installed on the cutting linear guide 24 through a laser cutting seat 241. The elevating column 23 and the cutting linear guide 24 are driven by the elevating hydraulic cylinder 22 to descend, and the cutting linear guide 24 drives the laser cutting seat 241, the cutting mounting seat 8 and the laser cutting main body 7 to move for laser cutting; One side of the adjusting moving seat 21 is fixedly installed with an adjusting guide slider 25. One side of the cutting support seat 1 is provided with an adjusting guide chute 26. An adjusting screw 28 is rotatably installed inside the adjusting guide chute 26. One end of the adjusting screw 28 is installed with a motor reducer 29. An adjusting nut 27 is fixedly installed inside the adjusting guide slider 25. The adjusting nut 27 is sleeved on the adjusting screw 28. During cutting, the motor reducer 29 drives the adjusting screw 28 to rotate. The adjusting screw 28 drives the adjusting guide slider 25 and the adjusting moving seat 21 to longitudinally move positions, and cooperates with the cutting linear guide 24 to laterally move the position of the laser cutting main body 7, so as to be able to fully cut each position of the polytetrafluoroethylene plate.

[0025] For the adjusting mechanism 2 adopting the above technical solution, during use, the elevating hydraulic cylinder 22 of the adjusting mechanism 2 drives the cutting linear guide 24 to rise and fall, thereby driving the heat exchange mechanism 3, the cooling mechanism 4 and the heating mechanism 5 to rise and fall for adjustment, which is convenient for quickly cutting each position of the polytetrafluoroethylene product.

[0026] Working principle and usage process of the present invention: When in use, place the polytetrafluoroethylene plate on the support grid 12. Drive the lifting column 23 and the cutting linear guide 24 to descend through the lifting hydraulic cylinder 22. The cutting linear guide 24 drives the laser cutting seat 241, the cutting mounting seat 8, and the laser cutting main body 7 to move for laser cutting. At the same time, the rotation motor 81 drives the rotation gear ring 83 to rotate. The rotation gear ring 83 cooperates with the rotation gear 82 to drive the cooling seat 41 or the heating seat 51 to rotate on the cutting mounting seat 8, thereby adjusting the positions of the cooling nozzles 44 or the heating nozzles 54. At the same time, the cooling adjustment electric rod 42 and the heating adjustment electric rod 52 drive the cooling rotating rod 43 and the heating rotating rod 53 to rotate angles, making the cooling nozzles 44 and the heating nozzles 54 more convenient to use. Through the operation of the ventilation pump 36, air passes through the heating pipeline 34 and the cooling pipeline 35. In cooperation with the heat absorption and heat release of the semiconductor refrigeration sheet 33, the air flow in the heating pipeline 34 and the cooling pipeline 35 is heated and cooled. Thus, the cutting position of the polytetrafluoroethylene plate can be heated and cooled through the heating nozzles 54 and the cooling nozzles 44. Heating can accelerate the cutting speed of the laser cutting main body 7 on the polytetrafluoroethylene plate, and cooling can rapidly lower the temperature. During cutting, the motor reducer 29 drives the adjustment screw rod 28 to rotate. The adjustment screw rod 28 drives the adjustment guide slider 25 and the adjustment moving seat 21 to longitudinally move positions, and cooperates with the cutting linear guide 24 to horizontally move the position of the laser cutting main body 7, so as to be able to fully cut all positions of the polytetrafluoroethylene plate. Through the driving rotation of the rotation motor 81 and the angle adjustment driven by the cooling adjustment electric rod 42 and the heating adjustment electric rod 52, it is ensured that the cooling nozzles 44 and the heating nozzles 54 are more convenient to use. During use, the mounting cross beam 61 moves along with the adjustment moving seat 21, so as to conveniently cooperate with the collection linear guide 66 to drive the air extraction head 65 to move positions. Through the operation of the air extraction collection pump 63, air extraction and suction are performed on the cutting position, so as to ensure that harmful gases and waste residues generated at the cutting position are fully extracted and collected during use. The extracted harmful gases and waste residues enter the filter element 620 through the adjustment partition plate 623 for filtering and collection. After using for a period of time, through the transmission of the transmission worm 626 and the transmission worm gear 627, the adjustment motor 625 drives the adjustment screw rod 628 to rotate, so that the adjustment screw rod 628 drives the sealing cover plates 629 at both ends to move, thereby the sealing cover plates 629 at both ends block one end of the filter element 620 and the other end of the filter element 620 is opened for use, and the filter element 620 can be cleaned without stopping the machine.
