In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] like Figure 1 As shown, a smoke exhaust bellows for a TMT texturizing machine which is convenient for replacing a filter screen comprises a U-shaped bellows 1, a cover 2 arranged on the top of the U-shaped bellows 1, and through holes 3 arranged on both sides of the U-shaped bellows 1. A vertically arranged track groove 4 is symmetrically arranged on the inner side of the U-shaped bellows 1, and a detachable square filter screen 5 is arranged in the track groove 4. Both sides of the square filter screen 5 are limited and closed by the track groove 4, and the upper and lower ends of the square filter screen 5 are sealed and pressed and closed by the cover 2, and the square filter screen 5 is disassembled and assembled by pushing and pulling up and down through the track groove 4.

[0022] When the texturizing machine transports the oil smoke volatilized by heat into the bellows through the smoke exhaust pipe during production, and then enters the smoke exhaust fan for purification and discharge after being filtered through the bellows, the existing filter structure in the bellows is improved, and a vertical track groove 4 installed up and down is installed on each of the two side surfaces inside the U-shaped bellows 1, and the filter is transformed into a square filter 5 that fits the internal cavity of the bellows, and the square filter 5 is slidably disassembled and fixed through the track grooves 4 on both sides. When the square filter 5 needs to be installed, it only needs to slide the two sides of the square filter 5 downward along the track grooves 4, and then cover the cover 2, so that the oil smoke and impurities can be filtered through the square filter 5, and when it needs to be disassembled, it only needs to be removed. It is only necessary to open the cover 2, and then pull the square filter 5 upwards for disassembly. It is no longer necessary to fix it with screws, so that the disassembly and assembly of the square filter 5 is simple and convenient. The square filter 5 can be disassembled and assembled by pulling out through the track groove 4, thereby solving the problem that the existing circular filter is difficult to disassemble and assemble due to the narrow space of the bellows. At the same time, when cleaning the inside of the bellows, the square filter 5 can be quickly disassembled and assembled, thereby facilitating the internal cleaning of the bellows, making the improved square filter 5 more suitable for disassembly and cleaning with alkaline water, making it more convenient to disassemble and clean the filter, and at the same time greatly improving the safety of the filter during disassembly and cleaning, avoiding damage to the filter when cleaning the bellows with alkaline water, and having strong practicality and promotion.

[0023] As a further improvement, the track groove 4 includes a long strip mounting rail 42 and a U-shaped slide groove 41 arranged at the front side of the mounting rail 42 , and the width of the U-shaped slide groove 41 is 0.5 to 1 mm greater than the side thickness of the square filter 5 .

[0024] It is more convenient and simple to disassemble and assemble the square filter 5, and it is not easy to get stuck.

[0025] A further improvement is that the U-shaped slide groove 41 is arranged to penetrate vertically.

[0026] The structure of the track groove 4 is simpler, and can make the upper and lower sides of the square filter 5 fit more closely after installation, thus avoiding the generation of gaps.

[0027] As a further improvement, the mounting rail 42 is fixed at a corner of one side of the U-shaped bellows 1 .

[0028] It is more convenient to position the mounting rail 42, and the positioning accuracy is higher after positioning. When the U-shaped bellows 1 needs to be cleaned, the mounting rail 42 will not affect the cleaning of the inside of the U-shaped bellows 1. At the same time, the square filter 5 can be closer to the position of the original filter, so that the storage space in the bellows is larger.

[0029] As a further improvement, the mounting rail 42 is fixed in the U-shaped bellows 1 by welding or screws.

[0030] The mounting rail 42 is more secure when being fixed, especially when being fixed with screws, and the on-site installation of the mounting rail 42 in the U-shaped bellows 1 is more convenient and the operation difficulty is lower.

[0031] Further improvement is as follows: Figure 2 As shown, a sealing strip 6 is provided at the bottom of the sealing cover 2 , and the sealing strip 6 is used to seal the sealing cover 2 and the square filter 5 .

[0032] In order to prevent the oil smoke from passing through the gaps on the upper and lower sides after the cover 2 is closed, a sealing strip 6 is installed at the bottom of the cover 2. After the square filter 5 is pressed by the sealing strip 6, this technical problem can be effectively solved. The sealing strip 6 is a rectangular structure, and the width of one side is greater than the width of the other sides. The entire sealing strip 6 is clamped and sealed by the cover 2 and the U-shaped bellows 1, which can solve the problem that the sealing strip 6 is difficult to install and easy to deform.

[0033] A further improvement is that the square filter screen 5 adopts a 540*540mm square filter screen 5 with a rim width of 40mm and a thickness of 9mm.

[0034] It has a higher fit with the internal contour of the existing U-shaped bellows 1 and better sealing, especially its edging width is 40 mm and thickness is 9 mm, which has a longer service life than the square bellows and better firmness after installation.

[0035] A further improvement is that the square filter screen 5 is made of a stainless steel mesh with a hole spacing of 3 mm.

[0036] The original smoke exhaust filter mesh has a hole pitch of 2mm. The square filter 5 is now changed to a stainless steel mesh with a hole pitch of 3mm, which increases the wind pressure flow, reduces the load on the fan motor, and the square filter is more suitable for removal and cleaning with alkaline water. After the modification, the original filter mesh has improved the problems of increased load on the smoke exhaust fan and reduced negative pressure in the smoke exhaust pipe due to the accumulation of oil stains due to the small aperture of the original filter mesh. After the modification, the filter mesh is easier to disassemble and clean, and the safety of the filter mesh during disassembly and cleaning and the damage to the filter mesh during alkaline water cleaning are greatly improved.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
