The device is equipped with a controller, and the controller is electrically connected to the device.

[0021] In the embodiment, a first rotating hot pressing roller 307 is sleeved on the first fixing rod 306. First L-shaped limiting rods 308 are symmetrically fixed at the outer ends of the first fixing rods 306. First limiting vertical holes 102 adapted to the first L-shaped limiting rods 308 are opened on the arched plate 101. Second lifting plates 4 are symmetrically sleeved on the first screw rod 3.

[0022] In an embodiment, a sleeve plate 302 is sleeved on the middle parts of the first stud 3 and the second stud 301. The sleeve plate 302 is fixed to the arched plate 101. The first stud 3 and the second stud 301 are slidably connected to the sleeve plate 302.

[0023] In an embodiment, the limiting assembly includes first limiting rods 2 symmetrically arranged on a workbench 1. A second limiting rod 202 is arranged on one side of the first limiting rod 2. The second limiting rods 202 are symmetrically arranged. A first limiting roller 201 is rotatably sleeved on the first limiting rod 2.

Fixed blocks 204 are fixed to the outer ends of the first limiting rod 2 and the second limiting rod 202. The fixed blocks 204 are fixed to the workbench 1. A composite sheet 205 is wound on the first limiting roller 201 and the second limiting roller 203. Among them, the composite sheet 205 includes a first sheet at the top position, a hot melt adhesive film in the middle position, and a second sheet at the bottom position. The first sheet, the hot melt adhesive film, and the second sheet are unreeled into the arched plate 101 through an unreeling mechanism at one side position of the arched plate 101. After the first sheet, the hot melt adhesive film, and the second sheet are compounded, a winding operation is performed through a winding mechanism at the other side position of the arched plate 101.

[0024] Working principle: When using this device, the composite sheet 205 to be compounded sequentially passes through the first limiting roller 201 and the second limiting roller 203 at one side position, passes through the arched plate 101, and then passes through the second limiting roller 203 and the first limiting roller 201 at the other side position to ensure the smooth progress of the winding and unreeling operations and complete the limiting operation. When performing the compounding operation, the rotating motor is controlled to start. The rotating motor drives the first stud 3 and the second stud 301 to rotate synchronously under the action of the belt 304. As a result, the two first lifting plates 305 and the two second lifting plates 4 move closer to each other until they clamp the composite sheet 205. Under the rolling of the composite sheet 205, multiple first rotating hot pressing rollers 307 and second rotating hot pressing rollers 402 rotate to perform synchronous hot pressing operations on the top and bottom of the composite sheet 205, ensuring the effect of the hot pressing.
