[0022] Figure 1 This is a schematic diagram of the structure of a double-layer corrugated bonding machine in some embodiments of this utility model. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 The figure shows a preferred embodiment of the present invention, which discloses a double-layer corrugated bonding machine, including an upper pressing body 2, a conveying assembly 3, and a heating part 4. The upper pressing body 2 and the heating part 4 are respectively disposed on the upper and lower sides of the conveying assembly 3.

[0025] The top of the upper laminator 2 is provided with multiple lifting control components. The upper laminator 2 includes a first driving roller, a first driven roller, a tensioning roller and a conveyor belt. The first driving roller, the first driven roller and the tensioning roller are connected in series through the first conveyor belt. The first driving roller is connected to the output shaft of the first power mechanism.

[0026] Conveying assembly 3 includes a second driving roller, a second driven roller, and a second conveyor belt. The second driving roller and the second driven roller are connected in series via the second conveyor belt. The second driving roller is connected to the output shaft of the second power mechanism.

[0027] The heating section 4 includes multiple heating tubes.

[0028] The two layers of corrugated paper that need to be bonded and conveyed are conveyed between the upper surface of the conveying component 3 and the lower surface of the upper laminator 2. During the conveying process, the upper surface of the two layers of corrugated paper that need to be bonded and conveyed contacts the lower surface of the upper laminator 2 (the lower surface of the first conveyor belt), and the lower surface of the two layers of corrugated paper contacts the upper surface of the conveying component 3 (the upper surface of the second conveyor belt).

[0029] The double-layer corrugated bonding machine includes a body 1 with thermal insulation, an upper pressing body 2, a conveying assembly 3, and a heating unit 4, all connected to the body 1. The specific structure of the body 1 can be as follows: it includes a frame and sealing plates. The upper pressing body 2, conveying assembly 3, and heating unit 4 are all connected to the frame. Sealing plates are installed on at least the feed side (right side), bottom, front side, and rear side of the frame. The sealing plates are provided with an insulation layer, which can be made of insulation materials such as asbestos.

[0030] The lifting control assembly has a lifting platform at its bottom. The first driving roller, the first driven roller, the tensioning roller, and the conveyor belt are all connected to the lifting platform. The roller rises or falls with the lifting platform, facilitating intelligent control of the distance between the upper laminator 2 and the conveying assembly 3. The first conveyor belt can be a commercially available high-temperature resistant conveyor belt. The upper laminator 2 specifically includes one first driving roller, one first driven roller, and two tensioning rollers. Generally, the two tensioning rollers are positioned below the driving and driven rollers. By tauting the lower surface of the first conveyor belt, making it parallel to the upper surface of the second conveyor belt, the two layers of corrugated paper to be bonded and conveyed are simultaneously pressed and transported. The lifting control assembly described here can be a cylinder.

[0031] The conveying assembly 3 may specifically include a second driving roller and a second driven roller.

[0032] The first power mechanism and the second power mechanism mentioned above may be the same power mechanism or may not be the same power mechanism. Both the first power mechanism and the second power mechanism may be electric motors or other existing equipment that can provide power.

[0033] In some specific implementations, the upper laminator 2 also includes an anti-opening pressure roller assembly 5, which is located at the discharge end of the double-layer corrugated bonding machine. The structure of the anti-opening pressure roller assembly 5 can be as follows: it includes a pressure roller, both ends of which are connected to the machine body or a lifting platform. A vertical groove is provided at the connection point. This groove guides the up-and-down movement of the pressure roller. When the pressure roller presses down to the bottom of the groove under its own weight, the bottom surface of the pressure roller contacts the upper surface of the first conveyor belt. When the double-layer corrugated paper to be bonded passes beneath it, the pressure roller presses down under its own weight, further pressing the double-layer corrugated paper to be bonded and improving the bonding effect.

[0034] The heating part 4 mentioned above includes a shell. The structure of the shell can be: auxiliary sealing plates are provided around the shell and at the bottom. The heating tube is embedded in the shell. The material of the auxiliary sealing plate can be a heat storage aluminum plate material, such as existing heat storage aluminum plate materials such as heat storage ceramic fiber aluminum silicate board refractory insulation material. The heat storage aluminum plate material can also be replaced with other heat storage refractory insulation materials.

[0035] The number of heating tubes installed in the heating section 4 can be six.

[0036] A temperature control component can be added inside the aforementioned housing. This component facilitates subsequent temperature control and enables automatic temperature adjustment during heating. The temperature control component described here includes a PT100 temperature sensor. This component can be implemented using existing technology and will not be elaborated upon here.

[0037] The operation process of the double-layer corrugated bonding machine is as follows: the lifting control component adjusts the distance between the upper pressing body 2 and the conveying component 3 according to the required bonding thickness of the double-layer corrugated paper. The heating unit 4 is turned on to enter the heating mode. The preceding equipment conveys one layer of glued corrugated paper and one layer of unglueed corrugated paper into the double-layer corrugated bonding machine, between the upper pressing body 2 and the conveying component 3. At this time, the corresponding power mechanisms of the upper pressing body 2 and the conveying component 3 are activated. The upper pressing body 2 and the conveying component 3 laminate the two layers of corrugated paper, achieving the effect of laminating and conveying at the same time, which improves the automation concept and effectively improves efficiency.

[0038] All of the above-mentioned undisclosed matters can be implemented using existing technologies, so they will not be elaborated here.

[0039] The aforementioned double-layer corrugated bonding machine can also be used for bonding multi-layer corrugated paper.
