[0002] Coating the surface of foam molds plays a significant role in improving the surface quality of products, enhancing performance, optimizing production efficiency, and improving environmental friendliness. This process is widely used in many fields such as construction, industry, and art, providing important guarantees for the functionality and aesthetics of foam products.

[0003] For laminating flat materials, adhesive bonding is usually used, where the film is bonded together by bonding or hot pressing. However, for laminating the surface of square molds, spraying is often used. Anti-corrosion, anti-scratch, and moisture-proof coatings are sprayed onto the surface of the foam mold to prevent surface damage during transportation or use. The specific operation usually involves suspending the foam mold, then using a handheld spray gun to carefully spray the entire surface, and then sending it to a drying oven for drying. The overall operation is relatively slow. Utility Model Content

A heating tube 71 and a temperature sensor are fixed inside the drying box 7. An exhaust pipe 72 is fixed at the top of the drying box 7.

[0019] The tilting conveyor assembly includes a track trough 8, a track block 81, and a fixed rack 87. The track trough 8 is located on the side wall of the outer spraying frame 3 and the drying chamber 7. The track block 81 is slidably connected to the track trough 8. A cylinder 84 is installed on the side of the track block 81 close to it. A clamping plate 85 is rotatably connected to the output end of the cylinder 84. A transmission gear 86 is fixed around the clamping plate 85. The fixed rack 87 is fixed between the outer spraying frame 3 and the drying chamber 7 and meshes with the transmission gear 86. The position of the fixed rack 87 is aligned with the tilting gap between the primary conveyor belt 11 and the secondary conveyor belt 12.

[0020] Working principle: First, connect the entire device to an external power source. Then, place the mold onto the primary conveyor belt 11. The primary conveyor belt 11 transports the mold through the two side spraying racks 2 and into the drying chamber 7 in the middle. While passing through the side spraying racks 2, the spray nozzles 6 on both sides of the mold can be used for spraying. The mold then enters the drying chamber 7 for drying, forming a solid protective mold on both sides. When it reaches the end of the primary conveyor belt 11, the cylinder 84 drives the clamping plate 85 to clamp and fix the mold. At this time, the sliding of the track block 81 allows the mold to pass through the outer spraying rack 3 and enter the drying chamber 7 at the end. While entering the outer spraying rack 3, the top spray nozzle... 6. Surface spraying is performed, and the meshing transmission of the fixed rack 87 of the transmission gear 86 ensures that the clamping plate 85 rotates synchronously during the sliding process, thereby driving the mold to flip so that all surfaces can be sprayed. Finally, it enters the end drying box 7 for drying. After moving to the front end of the secondary conveyor belt 12, the mold is released and flows out with the secondary conveyor belt 12. At this time, the track block 81 is reset to process the next mold. The whole process realizes the purpose of automatic spray coating. During this process, the synchronous drive of the synchronous motor 83 drives the threaded rod 82 to rotate, which allows the track block 81 to slide horizontally, coating all angles of the mold periphery at one time. The operation is simple and the work efficiency is improved.
