Description

Technical Field

[0001] The utility model relates to the technical field of filter bag production, in particular to a hot-melt film-sticking integrated machine for filter bags with an air purification function. Background Art

[0002] A filter bag is a filter material specially used for filtering solid particles, liquid suspended solids, etc. It is usually made of fiber material and is in the shape of a bag. When the filter bag is produced, the upper and lower filter cloth surfaces are pressed against a heating tool through hot-melt connection to heat the flat end surfaces until they melt. After removing the heating tool, the two melted end surfaces are pressed against each other and kept under pressure until the joint cools, so that the upper and lower filter cloth surfaces are connected as a whole. After the filter bag is hot-melt connected, it needs to be sewn and fixed at the joint, and after sewing, a film needs to be applied to the surface of the filter bag.

[0003] When some existing filter bag hot melt film laminating machines are in use, they are not equipped with special gas treatment mechanisms to capture and purify the toxic gases generated during hot melting, and are unable to prevent the leakage of these toxic gases, which can easily pollute the working environment and pose a threat to the health of operators.

[0004] For example, a hot melt film laminating machine for filter bags is disclosed with announcement number CN213035330U. The hot melt film laminating machine for filter bags of this patent clamps the right ends of the two overlapping filter materials with a spring clip fixedly installed on the left side of the traction plate, starts the speed regulating motor to drive the threaded rod to rotate, so that the traction plate threadedly connected to the threaded rod moves to the right, turns on the heating air gun to heat the cloth or film on the upper and lower sides to melt the surface, and then uses the telescopic cylinder inside the pressure mechanism one to lower the pressure wheel to press the side surfaces of the two cloth layers, so that the side surfaces of the upper and lower cloth layers are bonded together, and the film and filter cloth are rotated and pressed under the pressure wheel inside the pressure mechanism two to complete the film laminating, thereby speeding up the production speed of the filter cloth and reducing the production cost.

[0005] During the hot melting process of the filter bag, toxic gases such as carbon monoxide, sulfur dioxide, and volatile organic compounds may be released. However, the hot melt laminating machine does not have a special gas treatment mechanism to capture and purify these toxic gases, and cannot prevent the leakage of toxic gases. The hot melt laminating machine is equipped with a heating air gun to heat and melt the surface of the filter cloth, and a fan to cool the filter cloth passing through, but these devices may blow the generated toxic gases out from the inside of the machine body during operation, thereby polluting the working environment and posing a threat to the health of the operator.

[0006] Therefore, it is necessary to invent a hot-melt film-sticking integrated machine for filter bags with air purification function to solve the above problems. Utility Model Content

[0035] Working principle of this utility model:

[0036] Refer to the instruction manual Figure 1-4 When using the utility model, firstly, two filter cloths are respectively inserted into the working box 1 from two feed ports, and the feed slide roller 19 is used to ensure that the filter cloths enter smoothly;

[0037] The two filter cloths are tensioned by two tensioning rollers 2 to ensure that the filter cloths remain flat during processing. The two filter cloths pass through the top and bottom of the electric heating roller 4 respectively, and the pressing roller 3 presses the filter cloths against the surface of the electric heating roller 4 to heat them.

[0038] The edges of both sides of the filter cloth are heat-melted by the electric heating roller 4, and toxic gas may be generated at this time. One of the exhaust fans 13 starts to work, and the gas generated during the heat melting is quickly extracted into the air guide pipe 11 and transported to the air purifier 10 for purification.

[0039] The two hot-melted filter cloths are preliminarily pressed together by two No. 1 pre-pressing rollers 5, so that the hot-melted parts are bonded to each other, and then the No. 1 motor 14 is started to drive the two No. 1 squeezing rollers 6 through gears and belts to perform secondary squeezing on the filter cloths, thereby enhancing the connection firmness between the filter cloths;

[0040] The welded filter cloth passes between two sets of shaping rollers 7, and the cooling fan 8 blows the filter cloth upward to promote the rapid cooling and shaping of the hot-melt part. At this time, some toxic gases that have not been dissipated in time may still be attached to the filter cloth. Another exhaust fan 13 starts to work to extract the toxic gases blown out during the cooling process to the air purifier 10 for purification;

[0041] When the filter cloth after cooling and shaping passes through the sewing mechanism 9, the fusion bonding part on the filter cloth is sewn and fixed by the sewing mechanism 9, so as to further enhance the connection firmness between the filter cloths;

[0042] After welding, the filter cloth passes between two loading shafts 15 with film wrapped on the surface, and the film is pulled down and attached to the surface of the filter cloth. The film and the filter cloth are preliminarily pressed together by the No. 2 pre-pressing roller 16, and then the No. 2 motor 18 is started, and the two No. 2 squeezing rollers 17 are driven by gears and belt transmission to squeeze the film and the filter cloth for the second time, ensuring that the film and the filter cloth are tightly connected;

[0043] Finally, the filter cloth after hot-melt film lamination is pulled out through the discharge port, and the discharge roller 20 ensures that the filter cloth is discharged smoothly, thus completing the entire processing process.
