Description

Technical Field

[0001] This utility model belongs to the field of decorative veneer production technology, and in particular relates to a traction device based on an automatic spraying line for decorative veneers. Background Technology

[0002] The existing spraying line mainly includes a conveyor line (which can be a conveyor belt or roller conveyor). The sheet material is held on the conveyor line by gravity. The spraying section is arranged on the conveyor line. The nozzle group sprays the surface of the sheet material on the conveyor line from above. Various coatings can be sprayed to improve the performance of the sheet material.

[0003] During the spraying process, the panels fall onto the conveyor line solely by their own weight, resulting in poor adhesion between the panels and the conveyor line. This is especially problematic for thinner decorative veneers, where the light weight and the impact of spraying can cause instability in the panel's position, leading to uneven spraying, affecting spraying quality, and wasting material. If pressure rollers are placed above the conveyor line to press the panels, the coating may be damaged when passing over the rollers before it is dry. Therefore, pressure rollers can only be placed at the beginning of the spraying section. However, the pressure point is singular and has a small range, which still results in insufficient stability. Summary of the Invention

[0004] The purpose of this utility model is to provide a traction device based on an automatic spraying line for decorative veneer. Through the design of the traction device, the manifold box is connected to the bottom surface of the end of the board by suction cup.

[0030] The suction mechanism 2 includes a manifold box 201, a number of suction cups 202 are fixed on the top surface of the manifold box 201, a set of axles 203 are fixed on the bottom of the manifold box 201, and wheels 204 are fixed at both ends of the axles 203. The manifold box 201 is located between two rails 101, and the wheels 204 on both sides of the manifold box 201 roll along the two rails 101 respectively.

[0031] A mounting base 205 is fixed at the center of the bottom of the junction box 201. A set of telescopic tubes 206 is fixed on the bottom surface of the mounting base 205. A motor reducer 208 is fixed at the bottom end of the two telescopic tubes 206 through the base plate 207. A spring 209 is fixed between the base plate 207 and the mounting base 205 and is sleeved on the outside of the telescopic tubes 206.

[0032] The output end of the motor reducer 208 is fixed with a gear 210, which meshes with the rack 105.

[0033] Among them, such as Figure 4 As shown, both sides of the rail frame 1 are provided with conveyor lines 3, which are conveyor belts or roller conveyors. The area between the two downward inclined sections 102 of the rail body 101 is a straight section. The area above the straight section of the rail body 101 is the spraying area. A front pressure roller 4 is provided above the connection point between the downward inclined section 102 and the straight section at the front end of the rail body 101.

[0034] Among them, the bottom of the side plate 103 at the bottom of the two track bodies 101 is provided with a connecting beam 107, and a platform is provided at the bottom of several connecting beams 107.

[0035] Among them, such as Figure 1-2 As shown, an installation edge 108 is fixed on the inner side of the side plate 103 away from the rack 105, and a drag chain groove 109 is fixed on the top surface of the installation edge 108. A drag chain is provided in the drag chain groove 109, and the wires of the motor reducer 208 are arranged in the drag chain.

[0036] The manifold 201 has a flow divider chamber, and several suction cups 202 are connected to the flow divider chamber. A connector 211 is fixed at the bottom of the manifold 201, and an air pipe is connected to the connector 211. The air pipe is located inside the cable chain.

[0037] Among them, such as Figure 1 As shown, wheel 204 has an I-beam structure, and the two wheel edges of wheel 204 are in contact with the inner and outer sides of rail 101.

[0038] Among them, a downward-facing proximity sensor can be installed above the downward-sloping section 102 to detect the plate and the junction box 201.

[0039] The working principle of this utility model is as follows:

[0040] After the sheet material is conveyed to the bottom of the front pressure roller 4, it is detected by the proximity sensor, which controls the motor reducer 208 to run and control the gear 210 to rotate. The gear 210 first engages along the inclined section 106, correspondingly controlling the manifold 201 to move from the lower inclined section 102 of the front pressure roller 4 to the straight section. At this time, the manifold 201 is located directly below the sheet material, and due to the pressure of the front pressure roller 4, the suction cup 202 adheres to the bottom surface of the sheet material, realizing the connection between the sheet material and the manifold 201. The motor reducer 208 continues to drive the manifold 201 to move. The movement of the manifold 201 causes the sheet material to move through the spraying area. When the manifold 201 moves to the straight section near the tail end inclined section 106, it is detected by the proximity sensor, releasing the suction of the suction cup 202 and separating the manifold 201 from the sheet material. After the sheet material is completely output, the motor reducer 208 is reversed to drive the adsorption mechanism 2 to reset. During the reset, the speed of the motor reducer 208 is increased. During the traction, the speed of the motor reducer 208 is controlled to match the moving speed of the manifold 201 with the conveying speed of the conveyor line 3.
