[0044] The rolling unit 46 is used to press the top surface of one side of the filter cloth 1 in the X-axis direction onto the bottom surface of the other side of the filter cloth 1 in the X-axis direction.

[0045] The heating unit 45 can heat the filter cloth 1, causing the heat-fusible fibers in that part to melt. The rolling unit 46 presses the top surface of one side of the filter cloth 1 in the X-axis direction to the bottom surface of the other side in the X-axis direction, thus bonding the filter cloth 1 into a cylindrical shape. After subsequent processing, it can be made into a filter bag.

[0046] The hot-melt adhesive filter bag production equipment is equipped with a filter cloth side gathering mechanism 3 and an adhesive mechanism 4. Through the cooperation of the filter cloth side gathering mechanism 3, the guide plate 44, the heating unit 45 and the rolling unit 46, the guiding, continuous cylindrical forming and composite forming of both sides of the filter cloth 1 are realized. This not only greatly reduces the labor intensity of the workers, but also ensures strong work continuity and effectively improves work efficiency. At the same time, the composite work is carried out in a cylindrical state, achieving the effect of only bonding the overlapping parts of both sides of the filter cloth 1, effectively ensuring product quality and yield.

[0047] Specifically, the rolling unit 46 includes a side stacking seat 461, a pad 462, and a rolling roller assembly 463; the top of the side stacking seat 461 is detachably connected to the assembly groove 430, the pad 462 is connected to the downstream side of the side stacking seat 461, a first limiting groove 4611 is provided at the top near end of the side stacking seat 461, the opening of the first limiting groove 4611 faces one side of the filter cloth 1 in the X-axis direction; a second limiting groove 4612 is provided at the bottom near end of the side stacking seat 461, the opening of the second limiting groove 4612 faces the other side of the filter cloth 1 in the X-axis direction;

[0048] The roller assembly 463 includes a fixed plate 4631, a telescopic drive component 4632, a connecting block 4633, and a roller 4634.

The fixed end of the telescopic drive component 4632 is disposed on the fixed plate 4631, and the driving end of the telescopic drive component 4632 faces the pad 462. The connecting block is disposed on the driving end of the telescopic drive component, and the roller is rotatably assembled to the connecting block. The roller is disposed above the pad 462.

[0049] The first limiting groove 4611 and the second limiting groove 4612 on the side stacking seat 461 are arranged horizontally and vertically. The opening ends of the first limiting groove 4611 and the second limiting groove 4612 are arranged opposite to each other, and the first limiting groove 4611 and the second limiting groove 4612 arranged vertically have overlapping parts. The stacking of the two sides of the filter cloth 1 is completed by the guidance of the first limiting groove 4611 and the second limiting groove 4612 arranged opposite to each other. The structure is simple and the stacking effect is good.

[0050] Furthermore, the first limiting groove 4611 and the second limiting groove 4612 on the side stacking seat 461 serve a limiting function, ensuring that one side of the filter cloth 1 in the X-axis direction is stacked on top of the other side of the filter cloth 1 in the X-axis direction, preventing the side of the filter cloth 1 from moving and thus affecting the bonding quality. In practical applications, one side of the filter cloth 1 in the X-axis direction is embedded in the first limiting groove; the other side of the filter cloth 1 in the X-axis direction is embedded in the second limiting groove 4612.

[0051] The top surface of one side of the filter cloth 1 in the X-axis direction is stacked on the bottom surface of the other side of the filter cloth 1 in the X-axis direction, and the filter cloth 1 is conveyed along the X-axis direction; after the telescopic drive 4632 drives the connecting block 4633 and the roller 4634 to descend, the roller 4634 cooperates with the pad 462 to tightly press the top surface of one side of the filter cloth 1 in the X-axis direction onto the bottom surface of the other side of the filter cloth 1 in the X-axis direction, thereby achieving the purpose of bonding the two ends of the filter cloth 1.

[0052] The fixing plate 4631 is detachably connected to the assembly slot 430, and the operator can adjust the position of the roller assembly 463 installed in the assembly slot 430 as needed. In a specific embodiment of this utility model, the telescopic drive component 4632 is specifically a cylinder, which can drive the connecting block 4633 and the roller 4634 to rise or fall, thereby adjusting the distance between the roller 4634 and the pad 462.

The lower end of the first vertical rod 452 is connected to the first mounting block 453. The first pressure rod 454 and the first heating rod 455 are respectively disposed on the first mounting block 453, and the first pressure rod 454 is located above the first heating rod 455. A heating station is formed on one side of the filter cloth 1 between the first pressure rod 454 and the first heating rod 455.

[0055] The second heating assembly includes a second connector 456, a second vertical rod 457, a second mounting block 458, a second pressure rod 459, and a second heating rod 450. The second connector 456 is detachably connected to the assembly groove 430, and the upper end of the second vertical rod 457 is detachably connected to the second connector 456 in the vertical direction.

The operator can adjust the position of the first heating component or the second heating component installed in the assembly slot 430 as needed, thereby adjusting the specific position of the first heating component or the second heating component.

[0057] The first connector 451 and the second connector 456 have the same structure, the difference being that the first pressure rod 454 is located above the first heating rod 455, while the second heating rod 450 is located above the second pressure rod 459. The first pressure rod 454, being above the first heating rod 455, can heat the top surface of one side of the filter cloth 1 along the X-axis, causing the thermoplastic fibers in that area to melt. Similarly, the second heating rod 450, being above the second pressure rod 459, can heat the top surface of the other side of the filter cloth 1 along the X-axis, causing the thermoplastic fibers in that area to melt. The two positions are then pressed together by the rolling unit 46, thus bonding the filter cloth 1 into a cylindrical shape.

[0058] Moreover, the cooperation between the first pressure rod 454 and the first heating rod 455, as well as the cooperation between the second pressure rod 459 and the second heating rod 450, can achieve the purpose of tightening the sides of the filter bag.

[0059] The first vertical rod 452 and the first mounting block 453 are used to connect the first pressure rod 454, and the second vertical rod 457 and the second mounting block 458 are used to connect the second pressure rod 459.

[0063] In specific applications, the preheating device 521 can be a heating wire, an infrared heating lamp, or a hot air blower.

[0065] With the above structure, the guide plate 33 is provided with multiple arc-shaped guide grooves 330 of different lengths, which can meet the guidance of bag strip forming of different diameters. In addition, a transverse base 31 is added, which allows the operator to adjust the position of the guide plate 33 according to factors such as the thickness, hardness and size of the filter cloth 1, so that the side of the filter cloth 1 enters the filter bag assembly equipment relatively evenly, which facilitates the subsequent bonding of the filter bag, ensures the quality of bag strip forming, and meets the bonding requirements of bag strips of different diameters and materials.
