Description

Technical Field

[0001] This utility model relates to the field of plastic flooring processing technology, and more specifically to a UV coating device for plastic flooring. Background Technology

[0002] With the rapid development of the building decoration industry, plastic flooring has gradually become a substitute for traditional wood flooring due to its wear-resistant, waterproof, and environmentally friendly properties. UV coating technology, as the core process for surface treatment of plastic flooring, forms a high-hardness, scratch-resistant functional coating by applying a UV-cured coating to the substrate surface and allowing it to cure quickly, while also providing decorative effects such as matte, glossy, or textured finishes.

[0003] A search revealed Chinese patent CN222267630U, which discloses a UV coating device for plastic flooring. This device can coat plastic flooring of different thicknesses, effectively improving the applicability of UV coating devices for plastic flooring. However, after coating, excess coating will remain on both sides of the floor. If it is not treated, the coating will accumulate and solidify at the edges, forming burrs and affecting the smoothness of the edges. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4This utility model provides a UV coating device for plastic flooring, including a workbench 1. A U-shaped frame 2 is bolted to the upper surface of the workbench 1. An electric telescopic rod 3 is bolted to the top outer wall of the U-shaped frame 2. The output end of the electric telescopic rod 3 passes through the top inner wall of the U-shaped frame 2 and is bolted to a paint box 4. The bottom of the paint box 4 has two notches. Two paint rollers 5 are rotatably connected between the two inner walls of the paint box 4, and the bottom of the paint rollers 5 extends out to the outside of the paint box 4 through the notches. A material transfer assembly is provided on the upper surface of the workbench 1. Two symmetrical supports 18 are bolted together between the U-shaped frames 2. Two symmetrical guide rods 19 are bolted together between the two supports 18. Two symmetrical carriages 21 are slidably connected to the two guide rods 19. The bottom of each carriage 21 is detachably connected to a scraper 22 for scraping the adhesive from the side of the plastic flooring. The scrapers 22, which are symmetrically arranged on both sides, simultaneously scrape off the excess paint from the edge of the plastic flooring, effectively preventing paint from accumulating or forming burrs on the substrate edge. This ensures a smooth and flat transition area between the coated surface and the side edge, avoiding paint residue after subsequent curing. To prevent defects such as warping and cracking, a bidirectional lead screw 20 is rotatably connected between the two supports 18 and above the guide rod 19 via a bearing. The bidirectional lead screw 20 passes through the two slides 21 and is threaded to them. Through the synergistic action of the double scraper 22 and the bidirectional lead screw 20, it can adapt to the coating needs of plastic flooring of different widths, significantly improving process compatibility. In use, the uncut plastic flooring is first passed through the material transfer assembly on the left. When it passes below the paint box 4, the electric telescopic rod 3 is activated to extend. During the extension of the electric telescopic rod 3, the paint box 4 is moved downwards until it is flush with the bottom. The paint roller 5 and roller 15 are in close contact with the plastic flooring. During the conveying of the plastic flooring, the paint roller 5 will rotate. During the rotation of the paint roller 5, the paint in the paint box 4 will be carried out and applied to the plastic flooring. One end of the bidirectional lead screw 20 passes through one side of one of the brackets 18 and is fixed to the rotating disk by bolts. When conveying the plastic flooring, the drive motor 8 is started to drive the feeding roller 7 to rotate. Since the outer circumference of both feeding rollers 7 is provided with rubber sleeves 9, the rubber sleeves 9 squeeze and convey the plastic flooring, which is applicable to plastic flooring of different thicknesses.

[0023] In this invention, the bottom of each of the two scrapers 22 is detachably connected to two liquid guide rods 23 by bolts. An inclined collection box 24 is fixedly connected to the lower surface of the workbench 1, located below the multiple liquid guide rods 23, by bolts. After the adhesive is applied, the two scrapers 22 continue to scrape away excess paint from both sides of the plastic flooring. The scraped paint drips through the liquid guide rods 23 into the collection box 24 and is then discharged. When dealing with plastic flooring of different widths, the rotating disc drives the bidirectional lead screw 20 to rotate. During the rotation of the bidirectional lead screw 20, the two slides 21 move synchronously towards or away from each other along the guide rod 19 until the scrapers 22 contact the sides of the plastic flooring. With the cooperation of the liquid guide rods 23 at the bottom of the scrapers 22, the excess paint scraped by the scrapers 22 falls directly into the bottom collection box 24, allowing for the recycling and reuse of the paint, thus reducing raw material consumption costs.

[0024] In this utility model, the material transfer assembly includes two symmetrical fixed plates 6 that are fixedly connected to the upper surface of the workbench 1 by bolts. Two upper and lower feeding rollers 7 are rotatably connected between the two fixed plates 6 by bearings. Rubber sleeves 9 are glued to the outer circumference of the two feeding rollers 7. A drive motor 8 that enables one of the feeding rollers 7 to rotate along the axial direction is fixedly connected to one side of one of the fixed plates 6 by bolts.

[0025] In this utility model, inclined plates 14 are fixedly connected to both outer walls of the paint box 4 by bolts. One end of each inclined plate 14 is rotatably connected to a fixed shaft by bearings. Rollers 15 are fixedly connected to each fixed shaft by bolts. One end of the fixed shaft is fixedly connected to a pulley 16 by bolts. Both ends of the two paint rollers 5 pass through one outer wall of the paint box 4 and are fixedly connected to a pulley 17 by bolts. The pulley 17 and the pulley 16 are connected by belt drive.

[0026] In this utility model, two symmetrical side plates 10 are bolted to the upper surface of the workbench 1 and located between the inner walls of the two sides of the U-shaped frame 2. Support wheels 12 corresponding to multiple rollers 15 are rotatably connected to the opposite sides of the two side plates 10 through bearings. Support rollers 13 supporting two paint rollers 5 are rotatably connected between the two side plates 10 through bearings. The tops of the multiple support wheels 12 are at the same horizontal height as the tops of the two support rollers 13, and the bottoms of the multiple rollers 15 are at the same horizontal height as the bottoms of the two paint rollers 5.

[0027] The use of this utility model involves the following steps:

[0028] S1: When using, first pass the uncut plastic flooring through the conveyor assembly on the left. When it passes under the paint box 4, start the electric telescopic rod 3 to extend it. During the extension of the electric telescopic rod 3, it will drive the paint box 4 to move downward until it is in close contact with the paint roller 5 and roller 15 at the bottom and the plastic flooring. During the conveying of the plastic flooring, the paint roller 5 will rotate. During the rotation of the paint roller 5, the paint in the paint box 4 will be carried out and applied to the plastic flooring.

[0029] S2: After the glue is applied, the excess paint on both sides of the plastic floor is scraped off by two scrapers 22. The scraped paint drips into the collection box 24 through the liquid guide rod 23 and is then discharged. When dealing with plastic flooring of different widths, the rotating disc is used to drive the bidirectional screw 20 to rotate. During the rotation of the bidirectional screw 20, the two slides 21 move synchronously closer or further away along the guide rod 19 until the scraper 22 contacts both sides of the plastic flooring.

[0030] S3: When conveying plastic flooring, start the drive motor 8 to drive the feeding roller 7 to rotate. Since the outer circumference of both feeding rollers 7 is provided with rubber sleeves 9, the rubber sleeves 9 squeeze and convey the plastic flooring, which is applicable to plastic flooring of different thicknesses.
