Description

Technical Field

[0001] The invention belongs to the technical field of polytetrafluoroethylene processing, and in particular relates to laser cutting equipment for producing polytetrafluoroethylene products. Background Art

[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. Laser cutting, as a non-contact processing method, uses a high-energy laser beam to locally vaporize the material. It has the advantages of high processing accuracy and smooth, burr-free cuts. It is particularly suitable for the precision processing of thin products such as PTFE films and tapes with a thickness of ≤2mm. However, when applied to PTFE sheets with a thickness of ≥5mm, existing laser cutting technology faces significant challenges:

[0003] 1. PTFE has a low thermal conductivity (about 0.25 W / m·K). When laser cutting thick plates, heat easily accumulates in the cutting area, requiring a significant increase in laser power and a longer action time (for every 1mm increase in thickness, the cutting time is extended by 15% to 20%). This results in increased carbonization and burrs on the edges, seriously affecting the qualified rate of finished products.

[0004] 2. PTFE decomposes at high temperatures (>400°C) to produce harmful gases such as hydrogen fluoride (HF) and tetrafluoroethylene (TFE). Existing equipment mostly relies on external exhaust systems, but the gas collection efficiency is insufficient. Residual harmful gases pose a threat to the operating environment and personnel health.

[0005] 3. Existing technologies attempt to reduce cutting resistance by preheating or using a water cooling system for cooling. However, the heating and cooling processes are separated, making it difficult to coordinately control the temperature of the cutting area. This leads to concentrated thermal stress and exacerbated material deformation or cracking.

[0006] Therefore, it is necessary to design a laser cutting device for producing polytetrafluoroethylene products to solve the above problems. Summary of the Invention

[0048] Example 2: Please refer to Figures 1 to 8 As shown, on the basis of the first embodiment, the present invention provides a technical solution: the cleaning mechanism 6 includes a mounting crossbeam 61, a filter collection box 62 mounted on the mounting crossbeam 61, and an air extraction collection pump 63; a collection linear guide 66 is fixedly mounted on the upper side of the filter collection box 62 by bolts; an air extraction head 65 is mounted on the upper side of the collection linear guide 66 through a slide; the air extraction collection pump 63 and the air extraction head 65 are connected through a corrugated square tube 64; when in use, the mounting crossbeam 61 moves with the adjustment movable seat 21, thereby facilitating the cooperation with the collection linear guide 66 to drive the air extraction head 65 to move its position; the cutting position is exhausted and sucked by the operation of the air extraction collection pump 63, thereby ensuring that the harmful gases and waste residues generated at the cutting position are fully exhausted and collected when in use;

[0049] Further, see Figures 1 to 8, an adjustment partition 623 is fixedly installed on the inner side of the filter collection box 62, and a filter element 620 is connected to one side of the adjustment partition 623.

The harmful gases and residues generated by the cutting of polytetrafluoroethylene products can be collected and cleaned to avoid pollution to the working environment.

[0051] Further, see Figures 1 to 8The adjusting mechanism 2 includes an adjusting movable seat 21, a lifting hydraulic cylinder 22 is fixedly installed on the inner side of the adjusting movable seat 21, a lifting column 23 is fixedly installed on the piston rod of the lifting hydraulic cylinder 22, and the lifting column 23 is slidably installed on the inner side of the adjusting movable seat 21, and a cutting linear guide rail 24 is fixedly installed on the upper end of the lifting column 23 by bolts. The heat exchange mechanism 3 is installed on the upper side of the cutting linear guide rail 24, and the cutting mounting seat 8 is slidably installed on the cutting linear guide rail 24 through the laser cutting seat 241. The lifting hydraulic cylinder 22 drives the lifting column 23 and the cutting linear guide rail 24 to descend, and the cutting linear guide rail 24 drives the laser cutting seat 241, the cutting mounting seat 8 and the laser cutting body 7 to move for laser cutting; An adjusting guide slider 25 is fixedly installed on one side of the adjusting movable seat 21, and an adjusting guide slot 26 is opened on one side of the cutting support seat 1. An adjusting screw 28 is rotatably installed on the inner side of the adjusting guide slot 26, and a motor reducer 29 is installed on one end of the adjusting screw 28. An adjusting nut 27 is fixedly installed on the inner side of the adjusting guide slider 25, and the adjusting nut 27 is sleeved on the adjusting screw 28. During cutting, the motor reducer 29 drives the adjusting screw 28 to rotate, and the adjusting screw 28 drives the adjusting guide slider 25 and the adjusting movable seat 21 to move longitudinally, and cooperates with the cutting linear guide 24 to move the position of the laser cutting body 7 laterally, so that the polytetrafluoroethylene plate can be fully cut at various positions.

[0052] The adjusting mechanism 2 adopts the above technical solution. When in use, the lifting hydraulic cylinder 22 of the adjusting mechanism 2 drives the cutting linear guide rail 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, making it convenient and fast to cut various positions of the polytetrafluoroethylene product.

[0053] The working principle and use process of the present invention are as follows: when in use, the polytetrafluoroethylene plate is placed on the supporting grid 12, and the lifting hydraulic cylinder 22 drives the lifting column 23 and the cutting linear guide rail 24 to descend, and the cutting linear guide rail 24 drives the laser cutting seat 241, the cutting mounting seat 8 and the laser cutting body 7 to move for laser cutting.

At the same time, the cooling adjustment electric rod 42 and the heating adjustment electric rod 52 drive the cooling The rotating rod 43 and the heating rotating rod 53 are rotated at an angle to make the cooling nozzle 44 and the heating nozzle 54 more convenient to use. The operation of the ventilation pump 36 allows air to pass through the heating pipe 34 and the cooling pipe 35, and the heat absorption and heat release of the semiconductor refrigeration plate 33 are used to heat and cool the air flow in the heating pipe 34 and the cooling pipe 35. Therefore, the cutting position of the polytetrafluoroethylene plate can be heated and cooled by the heating nozzle 54 and the cooling nozzle 44. The cutting speed of the laser cutting body 7 on the polytetrafluoroethylene plate can be accelerated by heating, and the temperature can be quickly reduced by cooling. 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 movable seat 21 to move longitudinally, and cooperates with the cutting linear guide 24 to move the position of the laser cutting body 7 laterally, so that the polytetrafluoroethylene plate can be fully cut at various positions. The angle is adjusted by the driving rotation of the rotating motor 81 and the driving of the cooling adjustment electric rod 42 and the heating adjustment electric rod 52, so as to ensure that the cooling nozzle 44 and the heating nozzle 54 are more convenient when in use, and the installation beam 61 follows the movement of the adjusting movable seat 21 when in use, so as to facilitate the cooperation with the collection linear guide 66 to drive the exhaust head 65 to move the position, and the operation of the exhaust collection pump 63 The cutting position is vacuumed and sucked, thereby ensuring that the harmful gases and waste residues generated at the cutting position are fully vacuumed and collected during use. The vacuumed harmful gases and waste residues enter the filter element 620 through the adjustment partition 623 for filtration and collection. After a period of use, the adjustment motor 625 drives the adjustment screw 628 to rotate through the transmission worm 626 and the transmission worm gear 627, so that the adjustment screw 628 drives the sealing cover plates 629 at both ends to move, so that the sealing cover plates 629 at both ends block the filter element 620 at one end and the filter element 620 at the other end is opened for use, and the filter element 620 can be cleaned without stopping the machine.
