Description

Technical Field

[0001] This utility model relates to the technical field of PE bag heat sealing equipment, and in particular to a Teflon high-temperature cloth adjustment mechanism. Background Technology

[0002] During the production of PE bags, the bottom of the bag needs to be heat-sealed. This is usually achieved by heating the bag to about 140 degrees Celsius with a heating wire. However, since the heating wire is hot, direct contact with the PE bag can cause problems such as burns and adhesion on the surface of the PE bag. Therefore, in existing technologies, Teflon high-temperature cloth is pasted on the surface of the heating wire to provide isolation and protection.

[0003] However, after a long period of production and operation, the Teflon high-temperature cloth will show signs of wear and tear. At this time, the operators need to tear off the damaged Teflon high-temperature cloth and then re-attach a new Teflon high-temperature cloth. The operation process is cumbersome, reduces production efficiency, wastes Teflon high-temperature cloth material, and increases production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a Teflon high-temperature cloth adjustment mechanism to enable rapid adjustment and position replacement of the Teflon high-temperature cloth, thereby solving the technical defects of low efficiency and material waste in the existing PE bag production process.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A Teflon high-temperature cloth adjustment mechanism includes a fixed plate, an adjusting fixed plate, a first winding shaft, and a second winding shaft. The fixed plate and the adjusting fixed plate are arranged parallel to each other longitudinally, and the first winding shaft and the second winding shaft are arranged parallel to each other transversely. The two ends of the Teflon high-temperature cloth are respectively wound around the first winding shaft and the second winding shaft and pass around the dual-temperature heating strip. The first winding shaft and the second winding shaft transversely pass through two pairs of through holes in the fixed plate and the adjusting fixed plate. The rear end of the adjusting fixed plate is bent transversely and has a mounting plate. The mounting plate is longitudinally provided with an indexing pin. The end of the second winding shaft near the adjusting fixed plate is sleeved with an indexing block. The indexing pin cooperates with the indexing block for positioning. The indexing block can be unlocked or locked by pulling out or pressing the indexing pin. An adjusting nut is provided at one end of the second winding shaft.

[0006] Furthermore, a fixing nut, a washer, and a disc spring are fitted onto one end of the first winding shaft near the adjusting fixing plate, with the fixing nut, washer, and disc spring arranged sequentially from the outside to the inside.

[0007] Furthermore, the inner side of the fixing plate is provided with two bushings along the circumference of the two through holes, and the two bushings are respectively sleeved on the outer side of the first winding shaft and the second winding shaft.

[0008] Furthermore, it also includes a heat sealing mechanism, which comprises a sealing block mounting plate, a molybdenum sheet heating block, a foaming strip, a heat insulation board, a molybdenum sheet fixing block, a hot air plate fixing seat, and a resin fiberglass board.

[0009] This invention, through the coordinated design of the indexing pin of the adjustment plate and the indexing block of the take-up shaft, can quickly adjust and replace the position of the Teflon high-temperature cloth. The position of the high-temperature cloth can be adjusted simply by rotating the take-up shaft, so that the unworn part can continue to be used. There is no need to tear off the original high-temperature cloth and re-attach it, which reduces the consumption of high-temperature cloth, saves production costs, and improves production efficiency.

[0012] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] This embodiment discloses a Teflon high-temperature cloth adjustment mechanism, such as... Figure 2As shown, it includes a fixing plate 7, an adjusting fixing plate 8, a first winding shaft 1, and a second winding shaft 2. The fixing plate 7 and the adjusting fixing plate 8 are arranged parallel to each other in the longitudinal direction, and the first winding shaft 1 and the second winding shaft 2 are arranged parallel to each other in the transverse direction. The Teflon high-temperature cloth 12 has the specifications of 0.15mm thickness × 750mm width × 1000mm length, and is smooth and non-stick on both sides, with good high temperature resistance and anti-sticking performance. The first winding shaft 1 and the second winding shaft 2 transversely pass through two pairs of through holes in the fixing plate 2 and the adjusting fixing plate 8.

[0014] like Figures 1-4 As shown, the rear end of the adjusting fixing plate 8 is bent laterally and has a mounting plate. The mounting plate is longitudinally perforated with an indexing pin 11. The end of the second winding shaft 2 near the adjusting fixing plate 8 is fitted with an indexing block 9. The indexing pin 11 and the indexing block 9 are positioned together. The indexing block 9 can be unlocked or locked by pulling out or pressing the indexing pin 11. An adjusting nut 10 is provided at the head of one end of the second winding shaft 2. The first winding shaft 1, the second winding shaft 2, the adjusting fixing plate 8, the indexing block 9, and the indexing pin 11 are all made of 304 stainless steel, which is corrosion resistant and has high strength.

[0015] When the Teflon high-temperature cloth 12 is worn or damaged and needs to be replaced, the operator only needs to pull out the indexing pin 11 to unlock the indexing block 9. The heat-sealing position of the Teflon high-temperature cloth 12 can be adjusted by adjusting the indexing block 9 and rotating the adjusting nut 10. After the adjustment is completed, the indexing pin 11 is pressed down to lock and fix it.

[0016] like Figure 2 As shown, a fixing nut 3, a washer 4, and a disc spring 5 are sleeved on one end of the first take-up shaft 1 near the adjusting and fixing plate 8. The fixing nut 3, washer 4, and disc spring 5 are arranged sequentially from the outside to the inside. The disc spring 5 is made of 65Mn material, which has excellent elasticity. Through the elastic design of the disc spring 5 at the head of the first take-up shaft 1, the first take-up shaft 1 can move elastically along the axial direction and has a tensioning function. Through the coordinated action of the adjusting mechanism, the tension adjustment of the Teflon high-temperature cloth 12 can be assisted, ensuring the flatness of the Teflon high-temperature cloth 12 during the heat sealing process and improving the heat sealing quality of the PE bag.

[0017] Two bushings 6 are provided on the inner side of the fixing plate 7 along the circumference of the two through holes. The two bushings 6 are respectively sleeved on the outer side of the first winding shaft 1 and the second winding shaft 2 for circumferential positioning of the first winding shaft 1 and the second winding shaft 2.

[0018] The adjustment mechanism in this embodiment also includes a heat sealing mechanism, such as... Figure 1 As shown, the heat sealing mechanism includes a sealing block mounting plate 14, a molybdenum sheet heating block 15, a foaming strip 16, a heat insulation plate 17, a molybdenum sheet fixing block 18, a hot air plate fixing seat 19, and a resin fiberglass board 20. The above components are assembled together to ensure the stable operation of the heat sealing operation and the reliability of the adjustment function of the Teflon high-temperature cloth 12.

[0019] The adjustment mechanism of this embodiment is applied in a PE bag heat sealing equipment. During assembly, the two ends of the Teflon high-temperature cloth 12 are respectively wound around the first winding shaft 1 and the second winding shaft 2, so that the Teflon high-temperature cloth 12 passes around the dual-temperature heating strip 13, thereby isolating it from the heating wire in the molybdenum sheet fixing block 18.

[0020] When prolonged operation of the equipment causes localized wear or damage to the Teflon high-temperature cloth 12, first pull out the indexing pin 11. At this time, the indexing block 9 is in the unlocked state. Rotate the indexing block 9 to rotate the adjusting nut 10, which will drive the second take-up shaft 2 to rotate, moving the unworn part of the Teflon high-temperature cloth 12 to the heat sealing working position. The tension of the Teflon high-temperature cloth 12 is adjusted by the elastic action of the disc spring 5 of the first take-up shaft 1. After the position is adjusted, press down the indexing pin 11 to lock the indexing pin 11 with the indexing block 9, fixing the position of the Teflon high-temperature cloth 12, and the heat sealing operation can be resumed.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
