[0020] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1 to Figure 5 The device shown is a device for enhancing the bonding force between a hard coating and a substrate based on hot pressing coating, comprising an operating table 1, a U-shaped frame 18 is arranged above the operating table 1, a hanger 19 is fixedly connected to the upper surface of the operating table 1, and the U-shaped frame 18 is slidably arranged on the hanger 19. When in use, a drive motor, a lead screw and other structures are arranged on the hanger 19 to cooperate with the U-shaped frame 18, so as to drive the U-shaped frame 18 to move back and forth above the operating table 1 to expand the position of hot pressing coating. The substrate is placed on the operating table 1, and a fixed structure for positioning the substrate (not shown in the figure) is also arranged on the operating table 1 to prevent the substrate from moving during spraying. The fixed structure is a common existing technology and will not be described in detail here.

[0022] A square box 2 is arranged inside the U-shaped frame 18, and a partition frame 3 is fixedly connected inside the square box 2. The partition frame 3 is S-shaped and divides the inside of the square box 2 into an air chamber 4 and a liquid chamber 5, so that the inside of the square box 2 can transport both wind power and coating materials. A nozzle 17 is fixedly connected to the outer wall of the square box 2, and the nozzle 17 is connected to the liquid chamber 5. When the paint is transported to the square box 2, it will be sprayed out by the nozzle 17, and a plurality of nozzles 17 can be provided.

[0023] When spraying is required, the end of the slide box 6 close to the nozzle 17 is controlled to deflect downward, and the nozzle 17 performs the spraying operation.

[0024] In order to achieve the effect of hot pressing, a heating device 12 is fixedly installed inside the air cavity 4. The heating device 12 includes a heating block and other structures, which can quickly heat the gas passing through the air cavity 4. Both ends of the square box 2 are slidably connected with a slide box 6, and the slide box 6 is connected to the air cavity 4 through a square port 9. A pressing cylinder 7 is rotatably connected between the two slide boxes 6, and the two slide boxes 6 are connected to the pressing cylinder 7. Heat will enter the pressing cylinder 7 from the square port 9 and the slide box 6, so that the temperature of the pressing cylinder 7 increases.

[0025] The square box 2 is provided with a circular hole 8, which is connected to the air cavity 4. There are multiple circular holes 8, and the heated gas is directly sprayed toward the substrate through the circular holes 8. The structures such as the sliding box 6 and the pressing cylinder 7 can be made of heat-conducting materials.

[0026] At the same time, the heating device 12 can also heat the liquid chamber 5, so that the paint passing through the liquid chamber 5 remains in a hot melt state, thereby improving the spraying effect.

[0027] Before coating the substrate, the circular hole 8 is adjusted to a suitable height and directed toward the substrate to deliver gas to the inside of the air cavity 4. The heating device 12 can quickly heat the gas passing through the air cavity 4. The heated gas is sprayed from the circular hole 8 to the substrate. Heating the substrate and then spraying it can form a strong chemical bond on the surface of the substrate, thereby effectively improving the adhesion and corrosion resistance of the coating. At the same time, the surface temperature can be increased to improve the fluidity of the coating, thereby reducing the generation of defects such as bubbles and shrinkage cavities. In addition, heating can also promote the removal of volatiles on the surface of the substrate and avoid shrinkage cavities during the solidification process of the coating.

[0028] Furthermore, heating can also promote the curing process of the coating, improve the hardness and glossiness of the coating, and thus enhance the aesthetics and texture of the product.

[0029] When spraying, the air supply is stopped, and the end of the slide box 6 close to the nozzle 17 is controlled to deflect downward, and the nozzle 17 performs the spraying operation;

[0030] After the spraying is completed and the coating reaches a certain hardness, the pressing cylinder 7 also has a certain temperature, and the pressing cylinder 7 can be pressed and rolled on the coating to enhance the bonding force between the hard coating and the substrate.

[0031] In order to increase the thermal pressure of the pressing cylinder 7, support blocks 10 are fixedly connected to the inner walls of both sides of the air cavity 4, and springs 11 are fixedly connected to the support blocks 10. One end of the spring 11 away from the support blocks 10 is fixedly connected to the slide box 6. Specifically, the end of the slide box 6 close to the pressing cylinder 7 is controlled to deflect downward, and the pressing cylinder 7 is attached to the hardened coating. During the rolling process, the pressing cylinder 7 will be compressed by the sliding box 6 to squeeze the spring 11, and the restoring elastic force of the spring 11 makes the pressing cylinder 7 attached to the coating.

[0032] In addition, a slide box 6, a spring 11 and other structures are provided so that the distance between the pressing cylinder 7 and the square box 2 can be adjusted, so that the square box 2 can be deflected at multiple angles (refer to Figure 1 , Figure 2 ).

[0033] One side of the U-shaped frame 18 is rotatably connected to the air duct 13, which is fixedly connected to the square box 2 and communicates with the air cavity 4. The other side of the U-shaped frame 18 is rotatably connected to the liquid pipe 15, which is fixedly connected to the square box 2 and communicates with the liquid cavity 5.

[0034] The U-shaped frame 18 is provided with a driving device 20 for driving the square box 2 to rotate through the air duct 13. The driving device 20 includes a driving motor and gears and other structures for driving the air duct 13 to rotate, thereby driving the square box 2 to rotate.

[0035] One end of the air duct 13 away from the square box 2 is connected to the factory's wind supply pipeline through the first rotary joint 14, and the air duct 13 transports wind to the inside of the wind cavity 4; one end of the liquid pipe 15 away from the square box 2 is connected to the factory's coating material supply pipeline through the second rotary joint 16, and the liquid pipe 15 transports paint to the liquid cavity 5.
