[0042] In order to more clearly illustrate the technical solution of the present invention, a preferred embodiment is provided below. Figures 1 to 7 A seamless bonding machine includes a chassis 1, a hot bonding device 2, a rolling device 3, a cooling device 4 and a filtering device 5, wherein:

[0043] The hot-melt device 2 includes an upper transmission belt 21, a lower transmission belt 22, and a plurality of heaters 23. The upper transmission belt 21 and the lower transmission belt 22 are distributed in an upper and lower manner and are both connected to the chassis 1. The upper transmission belt 21 and the lower transmission belt 22 are each provided with a plurality of heaters 23 inside. The heaters 23 are fixedly connected to the chassis 1. The chassis 1 is provided with a first driving component 24 for driving the upper transmission belt 21 and the lower transmission belt 22.

[0044] The rolling device 3 includes an upper pressing roller 31, a lower pressing roller 32 and a hydraulic control module 33. The upper pressing roller 31 is arranged inside the upper transmission belt 21 and is fixedly connected to the chassis 1. The lower pressing roller 32 is arranged inside the lower transmission belt 22. The hydraulic control module 33 is installed on the chassis 1 and is used to drive the lower pressing roller 32 to move closer to or away from the upper pressing roller 31.

[0045] The cooling device 4 is arranged outside the thermal bonding device 2 .

[0046] This bonding machine combines fabrics of different materials into new fabrics by hot-melt bonding. During the bonding process, the chemicals in the adhesive will decompose organic compounds (V0Gs), formaldehyde, benzene and other harmful substances into smoke gas at high temperatures. Figures 8 and 9 The filtration device 5 includes an air inlet 51, an air duct 52, and a filter box 53. The air inlet 51 is located at the rear end of the hot-bonding device 2 and above the rolling device 3, allowing the air inlet 51 to absorb the smoke generated during the fabric lamination. The input end of the air duct 52 is located behind the air inlet, and the output end is fixedly connected to the filter box 53. The filter box 53 is located at the lower end of the chassis 1. The filter box is equipped with a filter element 531 and an exhaust fan (not shown) for extracting the smoke. The side wall of the filter box is provided with an outwardly disposed exhaust port 532, which connects the filter box 53 with the outside air. The filtered gas is discharged from the exhaust port 532 to the outside of the seamless bonding machine to prevent contamination. In this embodiment, the air duct 52 is located inside the chassis 1, the filter box 53 is located at the front end of the chassis 1, and the exhaust port 532 is positioned forward.

[0047] As a preferred solution, the filter element 531 is provided with activated carbon. The activated carbon can absorb harmful substances such as organic compounds (VOCs), formaldehyde, benzene, etc. in the smoke gas.

[0048] The working process of the seamless bonding machine involved in the present invention is as follows: the material to be bonded is first placed on the lower transmission belt 22, and the lower transmission belt 22 drives the material to be bonded to be conveyed forward until the material to be bonded enters under the upper transmission belt 21, and the material to be bonded is clamped by the upper transmission belt 21 and the lower transmission belt 22. Since the upper transmission belt 21 and the lower transmission belt 22 are both heated by the heater 23, the material to be bonded is subjected to the action of heat pressure and bonded during the conveying process; in addition, when the material moves with the lower transmission belt 22, the hydraulic control module 33 drives the lower pressing roller 32 upward, so that the material is fully pressure-maintained when passing through the rolling device 3, thereby improving the bonding quality of the material. At this time, the gas generated during the hot pressing is sucked in by the air inlet 51 and then enters the filter element 531 through the air guide 52, and is discharged from the exhaust port 532 after being filtered by the filter element 531; finally, the bonded material is output to the cooling device 4, and the cooling device 4 fully cools and shapes the material. Compared with the existing cylinder pressurization method, the hydraulic pressurization method adopted in this application can not only ensure sufficient pressure, but also stable pressure application and good pressure maintenance effect, which can make the quality of the final processed product better.

[0049] In this embodiment, the hydraulic control module 33 includes an oil tank 331, an oil pump 332, an electromagnetic reversing valve 333, two flow dividing and collecting valves 334 and two oil cylinders 335; the two oil cylinders 335 are provided at both ends of the lower pressure roller 32 and are both installed on the chassis 1, and the output end of the oil cylinder 335 is connected to the lower pressure roller 32; the oil tank 331 is provided on the chassis 1, the oil pump 332 is provided in the oil tank 331, and the electromagnetic reversing valve 333 is respectively connected to the oil pump 332, the oil tank 331 and the two flow dividing and collecting valves 334. The collecting valves 334 are connected, any one of the diverter collecting valves 334 is connected to the bottom of the two oil cylinders 335, and the other diverter collecting valve 334 is connected to the top of the two oil cylinders 335; a one-way valve 336 is provided between the electromagnetic reversing valve 333 and the oil pump 332; a hydraulic lock 337 is provided between the diverter collecting valve 334 and the electromagnetic reversing valve 333; an overflow valve 338 is provided between the electromagnetic reversing valve 333 and the oil tank 331, and a remote control valve 339 is connected to the overflow valve 338. In actual application, the oil pump 332 is used to pump out the oil in the oil tank 331 and allow the oil to enter the two oil cylinders 335. During this process, the electromagnetic reversing valve 333 is used to control the flow direction of the oil, that is, to control the oil to enter any diversion and collection valve 334, so that the pistons in the two oil cylinders 335 can be raised or lowered at the same time. After the pistons move into place, the hydraulic lock 337 is closed accordingly to prevent the oil from flowing back, so that the position of the pistons in the oil cylinders 335 is fixed; and the addition of the overflow valve 338 can ensure that the internal pressure of the hydraulic control module 33 is constant, and the constant pressure of the hydraulic control module 33 is adjusted through the remote control valve 339.

[0050] In this embodiment, a plurality of support rollers 25 are provided inside the upper transmission belt 21 and the lower transmission belt 22. The support rollers 25 are used to support the upper transmission belt 21 or the lower transmission belt 22. The support rollers 25 are adjustable and mounted on the chassis 1. In actual use, the upper transmission belt 21 and the lower transmission belt 22 are supported by the support rollers 25. When the upper transmission belt 21 or the lower transmission belt 22 is over-tensioned or over-slack, the position of the support rollers 25 can be adjusted to correct the upper transmission belt 21 or the lower transmission belt 22. This prevents the upper transmission belt 21 or the lower transmission belt 22 from breaking or wrinkling during the hot pressing bonding process.

[0051] Furthermore, the chassis 1 is provided with a plurality of adjustment assemblies 26, each comprising a fixed block 261, a screw 262, and a slider 263. The fixed block 261 is fixedly connected to the chassis 1, and the slider 263 is disposed outside the fixed block 261 and is slidably connected to the chassis 1. The screw 262 is threadedly connected to the fixed block 261 and is rotationally connected to the slider 263. The ends of the support rollers 25 are connected to the corresponding sliders 263. In actual use, a staff member can adjust the position of the slider 263 by rotating the screw 262, thereby adjusting the support roller 25 to achieve the purpose of correcting the transmission belt. The above design makes the adjustment operation of the support roller 25 more convenient and reduces the staff's work difficulty.

[0052] In this embodiment, cooling device 4 comprises a conveyor belt 41 and an air cooler 42. Conveyor belt 41 is positioned outside lower conveyor belt 22 and is drivingly connected to chassis 1. Chassis 1 is provided with a second drive component that drives conveyor belt 41. Air cooler 42 is positioned within conveyor belt 41 and is fixedly connected to chassis 1. In actual use, air cooler 42 cools conveyor belt 41, while material fed onto conveyor belt 41 exchanges heat with the conveyor belt, rapidly cooling and setting the material.

[0053] In this embodiment, a scraper 27 is provided between the lower transmission belt 22 and the conveyor belt 41. The scraper 27 is fixedly connected to the chassis 1, with its blade close to the surface of the lower transmission belt 22. It should be understood that under the action of heat and pressure, materials tend to adhere to the lower transmission belt 22. The addition of the scraper 27 can scrape the materials off the lower transmission belt 22, preventing the materials from moving along with the lower transmission belt 22 to the lower end portion of the lower transmission belt 22.

[0054] In this embodiment, the first driving component 24 includes a motor, a driving roller, and a driven roller. The driving roller is arranged inside the upper transmission belt 21 and is in close contact with the upper transmission belt 21. It is connected to the chassis 1 for rotation. The driven roller is arranged inside the lower transmission belt 22 and is in close contact with the lower transmission belt 22. It is connected to the chassis 1 for rotation. A driving gear is installed on the driving roller, and a driven gear is installed on the driven roller. The driving gear and the driven gear are meshed. The motor is installed on the chassis 1 and is used to drive the driving roller to rotate. Preferably, the present application uses the upper pressure roller 31 as the driving roller and the lower pressure roller 32 as the driven roller. The lower pressure roller 32 is movably connected to the chassis 1.

[0055] In this embodiment, a roller 28 is provided on the side of the upper transmission belt 21 near the cooling device 4. The roller 28 is rotatably connected to the chassis 1 and has teeth disposed on its outer periphery. A transmission gear is mounted on the roller 28, which meshes with the driving gear. It should be understood that under the action of heat and pressure, material may adhere to the upper transmission belt 21. The addition of the roller 28 can scrape the material off the upper transmission belt 21, preventing it from moving along with the upper transmission belt 21 and onto its upper end.

[0056] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above.
