Description

Technical Field

[0001] This utility model relates to the field of stone-plastic flooring, specifically to a UV-curing coating spraying device for wear-resistant PVC flooring. Background Technology

[0002] PVC flooring is a type of flooring made of polyvinyl chloride. Due to its durability, wear resistance, ease of cleaning, and convenient installation, it is widely used in various places, such as residential, commercial, medical, and educational environments.

[0003] To improve wear resistance, PVC flooring is often coated with wear-resistant paint and UV paint (anti-ultraviolet curing paint) after production. However, after processing, the surface of PVC flooring often gets dusty due to static electricity or the workshop environment. Dust can hinder the direct contact between the paint and the surface of the object, resulting in reduced paint adhesion and problems such as peeling and flaking, which affect the durability of the coating. At the same time, UV coating should be protected from ultraviolet radiation during spraying to avoid insufficient coating thickness and premature curing. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem this utility model aims to solve is that after the stone plastic flooring is processed, the surface often becomes dusty due to static electricity or the workshop environment. Dust can hinder the direct contact between the UV coating and the object surface, resulting in reduced coating adhesion and easy peeling and flaking of the coating, which affects the durability of the sprayed coating. At the same time, UV coating should be protected from ultraviolet radiation during spraying to avoid insufficient coating thickness and premature curing.

[0008] A UV-curable coating spraying device for wear-resistant PVC flooring includes a spray box. A motor is located at the bottom of the spray box, with its shaft passing through the bottom and extending into the box. A base plate is located at one end of the motor shaft, and a mounting bracket is located on the base plate. A support is located on one side of the inner wall of the spray box, and an electric lead screw is mounted on this support. A first connecting seat is located on the nut of the electric lead screw. A support is also located on the other side of the inner wall of the spray box, and a sliding rod is mounted on this support. Bearing seats are located at both ends of the sliding rod, and a sliding seat is fitted onto the sliding rod. A transverse support plate is located above the electric lead screw, and a limiting plate is located above the transverse support plate. A second connecting seat is located between the transverse support plate and the limiting plate, and a fixing plate is located on the second connecting seat. A handle is located at one end of the fixing plate, and a paint spray gun and an air gun are located at the other end of the handle.

[0009] Furthermore, the bottom ends of the transverse support plate are provided with connecting plates, one end of which is fixedly connected to the first connecting seat, and the other end of which is fixedly connected to the sliding seat.

[0010] Furthermore, the placement rack consists of two sets connected by a square tube, and the motor is equipped with a motor fixing plate, which fixes the motor to the bottom of the spray box.

[0011] Furthermore, the first connecting seat and the second connecting seat have the same structure, which is U-shaped plate.

[0012] Furthermore, the width of the limiting plate is smaller than that of the transverse support plate, and a hollow cavity is left between the limiting plate and the transverse support plate.

[0013] (III) Beneficial Effects

[0014] The beneficial effects of this utility model are:

[0015] It can easily remove dust and spray paint from the surface of PVC flooring. The lateral position can be moved by hand holding the handle, so the spraying accuracy and speed can be controlled according to the site conditions. Before spraying the paint, the dust on the floor surface can be blown away with an air gun to improve the adhesion of the UV paint. At the same time, the spray box is open and several sides are shielded, so it can be used outdoors to avoid premature curing caused by UV radiation during the spraying process, which would lead to product defects.

Therefore, they should not be construed as limitations on this utility model.

[0022] Please see Figure 1-3 The device shown is an ultraviolet curing coating spraying device for wear-resistant PVC flooring. It includes a spray box 1, a motor 2 at the bottom of the spray box 1, a shaft of the motor 2 passing through the bottom of the spray box 1 and extending into the spray box 1, a base plate 3 at one end of the motor 2 shaft, a mounting rack 4 on the base plate 3, a bracket 5 on one side of the inner wall of the spray box 1, an electric lead screw 6 on the bracket 5, a first connecting seat 7 on the nut of the electric lead screw 6, a bracket 5 on the other side of the inner wall of the spray box 1, a sliding rod 8 on one side of the bracket 5, bearing seats 9 at both ends of the sliding rod 8, a sliding seat 10 on the sliding rod 8, a transverse support plate 11 above the electric lead screw 6, a limiting plate 12 above the transverse support plate 11, a second connecting seat 13 between the transverse support plate 11 and the limiting plate 12, a fixing plate 14 on the second connecting seat 13, a handle 15 at one end of the fixing plate 14, and a paint spray gun 16 and an air gun 17 at one end of the handle 15.

[0023] The bottom ends of the transverse support plate 11 are provided with connecting plates 11a. One end of the connecting plate 11a is fixedly connected to the first connecting seat 7, and the other end of the connecting plate 11a is fixedly connected to the sliding seat 10. The connecting plate 11a serves to connect the two ends of the transverse support plate 11 to the electric lead screw 6 and the slide rod 8 respectively, so that the transverse support plate 11 moves back and forth along the lead screw under the drive of the electric lead screw 6. The slide rod 8 serves to support and assist, and supports the other end of the transverse support plate 11 through the sliding seat 10, so that the transverse support plate 11 can slide on the slide rod 8 through the sliding seat 10. The sliding seat 10 acts similarly to a sleeve, sleeved on the slide rod 8 and can slide along the slide rod 8 to cooperate with the movement of the transverse support plate 11.

[0024] Please see Figure 1There are two sets of placement racks 4 connected by square tubes. The motor 2 is equipped with a motor fixing plate, which is fixed to the bottom of the spray box 1. The two sets of placement racks 4 can hold two pieces of PVC flooring at the same time. The placement rack 4 near the opening of the spray box 1 is the output end. After the spraying is completed, the PVC flooring can be rotated to the outlet by the rotation of the motor 2. Then it can be picked up by manual or robotic arm and placed on the placement rack 4. The motor 2 rotates and enters the box for spraying.

[0025] The width of the limiting plate 12 is smaller than that of the transverse support plate 11. The first connecting seat 7 and the second connecting seat 13 have the same structure and are U-shaped plates. The first connecting seat 7 is connected to the nut of the electric screw 6. Driven by the screw, the first connecting seat 7 can move in the Y direction to drive the transverse support plate 11. The second connecting seat 13 is located between the limiting plate 12 and the transverse support plate 11. Its U-shape allows it to slide in the hollow cavity between the limiting plate 12 and the transverse support plate 11, i.e., move in the X direction. However, the second connecting seat 13 is manually controlled to move. It is connected to the fixed plate 14. The operator holds the handle 15 to move it in the X direction along the transverse support plate 11. Therefore, the main function of the second connecting seat 13 is to be used as a slider, while the limiting plate 12 limits it.

[0026] The specific working principle is as follows: the PVC floor is placed on the placement rack 4 near the opening of the spray box 1, and then the motor 2 rotates and pulls it into the box. After that, the Y-direction position is adjusted by the motor screw 6, and then the operator holds the handle 15 to move it in the X-direction. After that, the dust on the surface of the PVC board is removed by blowing air with the air gun 17, and then the surface coating is sprayed by the paint spray gun 16.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
