[0023] See also Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of the present application, the heating module comprises: A heat storage frame 24 is disposed in the processing box 13, and a plurality of heat exhaust nozzles 25 are arranged symmetrically and in an array in the heat storage frame 24; A heating box 21 is disposed in the processing box 13, wherein a heating rod 26 is disposed in the heating box 21; and The output component is disposed on the processing box 13 and connects the heating box 21 and the heat exhaust nozzle 25 , so as to input the hot air flow in the heating box 21 into the heat exhaust nozzle 25 .

[0024] In a specific case of this embodiment, the output component includes: An exhaust box 22 is provided on the processing box 13, the exhaust box 22 is connected to the exhaust nozzle 25 and the heating box 21, and a one-way valve 27 is provided between the exhaust box 22, the exhaust nozzle 25 and the heating box 21; A second piston 28, movably disposed in the exhaust box 22; and The electric telescopic rod 23 is arranged on the processing box 13 and its movable end is connected to the second piston 28.

[0025] In another specific case of this embodiment, the glue coating module includes a loading box 17, a brush roller 18, a brush 19 and a glue storage tank 15; The feeding box 17 is arranged in the processing box 13, the glue storage tank 15 is arranged on the processing box 13 and is connected with the feeding box 17, the brush rollers 18 are in a group and are symmetrically and movably arranged on the feeding box 17, a groove 20 is formed on the brush roller 18, and the brush 19 is arranged in the groove 20.

[0026] In another specific case of this embodiment, the pressing modules are in two groups and are symmetrically arranged on both sides of the discharge port, and each group of the pressing modules includes a fixing seat 29 and a plurality of pressurizing nozzles 30; The fixed seat 29 is arranged on the roller seat 31, and a plurality of pressurizing nozzles 30 are arranged in an array on the fixed seat 29. The No. 2 piston 28 separates the exhaust box 22 into a No. 1 cavity and a No. 2 cavity. The No. 1 cavity connects the heating box 21 and the heat exhaust nozzle 25, and the No. 2 cavity is connected to the pressurizing nozzle 30 through a connecting pipe 33.

[0027] It should be noted that in this embodiment, the method of inputting airflow into the heat exhaust nozzle 25 and the pressurized nozzle 30 is not limited to the above-mentioned output components, and can also be directly replaced by a fan or an air pump. They are not listed here one by one, as long as the flow of the airflow can be controlled.

[0028] In the process of the corrugated paper passing through the processing box 13 along the feed port, it first passes through the heat storage frame 24, and the control box 2 controls the heating rod 26 to be energized to continuously heat the gas in the heating box 21, and then the electric telescopic rod 23 is energized and continuously extended to drive the second piston 28 to reciprocate along the exhaust box 22. In this process, the hot air flow in the heating box 21 can be drawn into the exhaust box 22 and finally discharged into the heat exhaust nozzle 25 and sprayed onto the surface of the corrugated paper, so as to achieve the heating treatment of the surface of the corrugated paper. Then, when the corrugated paper passes through the brush roller 18, it can be brought by the friction resistance between the two.

The surface paper is located on both sides of the corrugated paper. While the No. 2 piston 28 reciprocates along the exhaust box 22, the air in the No. 2 cavity can be continuously input into the pressurized nozzle 30. The pressurized nozzle 30 outputs airflow in the direction of the surface paper, so that the effect of airflow pressure can be used instead of the mechanical pressing method, which can reduce the damage to the corrugated paper structure and ensure the bonding effect between the surface paper and the corrugated paper.

[0029] See also Figure 1-Figure 4 As another preferred embodiment of the present application, the temperature-controlled coating device further includes a monitoring module, which is disposed on the mounting seat 3 and is used to monitor the remaining amount of corrugated paper on the first winding roller 5 and feed back to the control box 2.

[0030] In a specific case of this embodiment, the monitoring module includes: A slider 7 is movably arranged on a guide groove formed on the mounting seat 3; The resistance rod 8 is arranged on the slider 7 and is in resistance with the outermost layer of corrugated paper on the first winding roller 5; A monitoring box 6 is arranged on the mounting seat 3, wherein a No. 1 piston 10 is movably arranged in the monitoring box 6 and the two are elastically connected, and the No. 1 piston 10 is connected to the slider 7; The resistance bar 11 is arranged in the monitoring box 6 , and the No. 1 piston 10 is provided with a conductive block 12 which slidably cooperates with the resistance bar 11 .

[0031] In another specific case of this embodiment, a resistance reducing member is provided at one end of the abutment rod 8 away from the slider 7 to reduce the friction resistance between the abutment rod 8 and the corrugated paper.

[0032] It should be particularly noted that the resistance reducing member can be a ball or a roller 9. In the present embodiment, the resistance reducing member is preferably a roller 9, which is movably arranged on the resistance rod 8 and slidingly cooperates with the outermost layer of corrugated paper on the No. 1 winding roller 5. As for the specific model parameters of the roller 9, the best choice can be made according to the actual situation and is not specifically limited here.

[0033] In actual application, the remaining amount of corrugated paper on the No. 1 winding roller 5 is monitored by utilizing the friction cooperation between the roller 9 and the corrugated paper on the surface of the No. 1 winding roller 5, that is, as the No. 1 winding roller 5 continuously rotates, the number of corrugated paper layers on the No. 1 winding roller 5 gradually decreases, driving the slider 7 and the No. 1 piston 10 to move along the monitoring box 6, so that the conductive block 12 contacts different positions on the resistor bar 11, so that the resistance value of the circuit where the resistor bar 11 is connected to the control box 2 changes, and the control box 2 converts the resistance value into the remaining amount of corrugated paper, thereby facilitating the staff to directly monitor the remaining amount of corrugated paper from the control box 2 and facilitating the replenishment of corrugated paper.

[0034] See also Figure 1-Figure 8 In another embodiment of the present application, a temperature-controlled coating method for corrugated paper bonding includes the temperature-controlled coating device described in the above embodiment, and the specific steps of the temperature-controlled coating method are as follows: S100: The corrugated paper and the surface paper are respectively rolled up on the first winding roller 5 and the second winding roller 14, and the power element is energized and rotated by the control box 2 to drive the first winding roller 5 to rotate and release the corrugated paper; S200: The corrugated paper enters the processing box 13 through the feed port, and the heating module is controlled to heat both sides of the corrugated paper, and then the glue coating module is used to coat the heated surface of the corrugated paper with glue; S300: The heated and glue-coated corrugated paper can be discharged from the discharge port. At this time, the second winding roller 14 is controlled to rotate to release the cover paper, and the cover paper is bonded to both sides of the corrugated paper. At the same time, the pressing module is used to apply pressure to the cover paper, thereby effectively ensuring that the corrugated paper and the cover paper are tightly bonded.

[0035] How this application works: The corrugated paper and the surface paper are respectively wound up on the No. 1 winding roller 5 and the No. 2 winding roller 14, and the power element is controlled by the control box 2 to be energized and rotated to drive the No. 1 winding roller 5 to rotate and release the corrugated paper. In the process of the corrugated paper passing through the processing box 13 along the feed port, it first passes through the heat storage frame 24, and the heating rod 26 is controlled by the control box 2 to be energized to continuously heat the gas in the heating box 21, and then the electric telescopic rod 23 is controlled to be energized and continuously extended and retracted to drive the No. 2 piston 28 to reciprocate along the exhaust box 22. In this process, the hot air flow in the heating box 21 can be drawn into the exhaust box 22 and finally discharged into the heat exhaust nozzle 25 and sprayed onto the surface of the corrugated paper, so as to achieve the heating treatment of the surface of the corrugated paper. Then, when the corrugated paper passes through the coating roller 18, the friction resistance between the two can drive the coating roller 18 to rotate, and the brush 19 can contact the glue in the feeding box 17 and finally coat it on the surface of the corrugated paper. The corrugated paper with glue can be discharged from the discharge port. At this time, the No. 2 winding roller 14 is released to rotate and release the surface paper. The surface paper is located on both sides of the corrugated paper. While the No. 2 piston 28 reciprocates along the exhaust box 22, the air in the No. 2 cavity can be continuously input into the pressure nozzle 30. The pressure nozzle 30 outputs airflow in the direction of the surface paper, so that the effect of airflow pressure can be used instead of the mechanical pressing method, which can reduce the damage to the corrugated paper structure and ensure the bonding effect between the surface paper and the corrugated paper. The remaining amount of corrugated paper on the No. 1 winding roller 5 is monitored by utilizing the friction cooperation between the roller 9 and the corrugated paper on the surface of the No. 1 winding roller 5. That is, as the No. 1 winding roller 5 continuously rotates, the number of corrugated paper layers on the No. 1 winding roller 5 gradually decreases, driving the slider 7 and the No. 1 piston 10 to move along the monitoring box 6, so that the conductive block 12 contacts different positions on the resistor bar 11, causing the resistance value of the circuit where the resistor bar 11 is connected to the control box 2 to change, and the control box 2 converts the resistance value into the remaining amount of corrugated paper, thereby facilitating the staff to directly monitor the remaining amount of corrugated paper from the control box 2 and facilitating the replenishment of corrugated paper.
