[0037] The hot-melt device 2 includes an upper transmission belt 21, a lower transmission belt 22 and a plurality of heaters 23.

The chassis 1 is provided with a first driving component 24 for driving the upper transmission belt 21 and the lower transmission belt 22.

[0038] 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 approach or move away from the upper pressing roller 31.

[0039] The cooling device 4 is arranged outside the thermal bonding device 2 .

[0040] The working process of a seamless bonding machine involved in the utility model 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 forward until the material to be bonded enters the lower part of the upper transmission belt 21. At this time, the material to be bonded is clamped by the upper transmission belt 21 and the lower transmission belt 22, and because the upper transmission belt 21 and the lower transmission belt 22 are both heated by the heater 23, the material to be bonded is bonded by the heat pressure during the conveying process; in addition, when the material moves with the lower transmission belt 22, the hydraulic control module 33 will drive the lower pressure roller 32 upward, so that the material can be fully pressure-maintained when passing through the rolling device 3, thereby improving the bonding quality of the material; 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-maintaining effect, which can make the quality of the final processed product better.

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 the 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 piston position of the oil cylinder 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 by the remote control valve 339.

[0043] Furthermore, the chassis 1 is provided with a plurality of adjustment components 26, which include a fixed block 261, a screw 262 and a slider 263.

In actual application, the staff can change the position of the slider 263 by rotating the screw 262, thereby adjusting the support roller 25, so as 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 work difficulty of the staff.
