Description

Technical Field

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

[0002] PVC plastic flooring is flooring made primarily of PVC plastic. The raw materials for PVC plastic flooring are the same as those for ordinary plastics; in addition to resin, other auxiliary materials such as plasticizers, stabilizers, and fillers are added. However, PVC plastic flooring contains a relatively large amount of filler because it is rarely subjected to tensile, shear, or tearing forces during use, and is mainly subjected to pressure and friction.

[0003] In the production of plastic flooring, the coating process is one of the key steps. Its purpose is to uniformly coat the surface of the plastic flooring with a functional coating to improve its wear resistance, water resistance, and aesthetics. However, existing coating equipment is prone to coating sedimentation during storage and coating, resulting in uneven coating concentration on the flooring surface after coating. Furthermore, the precision of coating amount control during the coating process is insufficient, which can easily lead to coatings that are too thick or too thin, thus affecting the coating production effect of plastic flooring.

[0004] Therefore, we propose a plastic floor coating device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a plastic flooring coating device, which solves the problems mentioned in the background art, such as the coating material easily precipitating during storage and coating, resulting in uneven coating concentration on the floor surface after coating, and insufficient precision in controlling the amount of coating material during coating, which easily leads to coating that is too thick or too thin, thus affecting the production effect of plastic flooring coating.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] like Figure 1-6 As shown, an embodiment of the present invention provides a plastic flooring coating device, including a coating chamber 1 and a UV drying assembly 8 fixed to one side of the upper end face of the coating chamber 1, and further including:

[0032] The coating chamber 1 is the main supporting structure of the device, while the UV drying component 8 is used to quickly cure and dry the coated plastic flooring. The receiving and discharging trough 2 is located at the lower end of the coating chamber 1 and is used to store and recycle the coating. The coating chamber 1 is rotatably connected to a scraper roller 3, and a connecting shaft 6 is provided at the upper end of the coating chamber 1. The outer surface of the scraper roller 3 is uniformly provided with grooves 4, and the cross-section of the grooves 4 is set in a "V" shape. The grooves 4 are used to carry the coating and achieve uniform coating.

[0033] The conveyor shaft 7 is fixed on the upper end face of the coating chamber 1, and the scraper roller 3, the groove 4, the connecting shaft 6 and the outer surface of the conveyor shaft 7 are wrapped with plastic flooring components to form the conveying path of the plastic flooring.

[0034] A drive motor 5 is fixed to one end of the scraper roller 3, providing power for the rotation of the scraper roller 3. A stirring paddle 11 is installed inside the receiving and discharging trough 2. A linkage mechanism is fixed to one end of the scraper roller 3 and the stirring paddle 11 to drive the scraper roller 3 and the stirring paddle 11 to rotate synchronously. The linkage mechanism includes a synchronous pulley 9 and a synchronous pulley 10. The synchronous pulley 9 is fixed to one end of the outer surface of the scraper roller 3, and the synchronous pulley 10 is fixed to one end of the stirring paddle 11. The synchronous pulley 9 and the synchronous pulley 10 are connected by a synchronous belt to realize the synchronous transmission between the scraper roller 3 and the stirring paddle 11.

[0035] The linkage mechanism also includes a drive gear 12, a linkage gear 13, and a second stirring paddle 14. The drive gear 12 is fixed to the other end of the first stirring paddle 11. The linkage gear 13 is symmetrically meshed and connected to the left and right sides of the drive gear 12. The second stirring paddle 14 is fixed to the other end of the linkage gear 13 and is symmetrically located on the left and right sides of the first stirring paddle 11. The drive gear 12 is fixed to the other end of the first stirring paddle 11, and the two linkage gears 13 are meshed and connected to the left and right sides of the drive gear 12 respectively. The second stirring paddle 14 is fixed to the other end of the linkage gear 13, ensuring that both the first stirring paddle 11 and the second stirring paddle 14 are located inside the receiving and discharging trough 2. This achieves synchronous rotation of multiple sets of stirring paddles and improves the stirring effect.

[0036] A support plate 15 is fixed inside the coating chamber 1, and through holes are evenly distributed on the lower end face of the support plate 15 for the return of excess paint. A scraper 16 is rotatably connected to the upper end of the support plate 15, and the scraper 16 contacts the bottom of the plastic floor piece to achieve secondary leveling. One side of the upper end face of the support plate 15 is inclined to facilitate the collection and return of paint. A filter screen 17 is slidably engaged inside the support plate 15. The mesh size of the filter screen 17 is 200-300μm, used to filter and recover impurities in the paint.

[0037] When in use, inject an appropriate amount of paint into the receiving and discharging trough 2, start the drive motor 5, and the drive motor 5 will drive the scraper roller 3 to rotate;

[0038] The scraper roller 3 drives the agitator 11 to rotate through the synchronous pulley 9 and the synchronous pulley 10. The agitator 11 drives the agitator 14 on both sides to rotate synchronously through the meshing of the drive gear 12 and the linkage gear 13, so as to fully agitate the paint in the collection tank 2 and prevent sedimentation.

[0039] One end of the plastic flooring piece is successively wrapped around the conveyor shaft 7 and the connecting shaft 6 and is set to fit the surface of the scraper roller 3. When the scraper roller 3 rotates, the "V"-shaped groove 4 on its surface carries the coating and evenly coats the surface of the plastic flooring piece.

[0040] The coated plastic flooring piece continues to be conveyed. When it passes above the support plate 15, the scraper 16 contacts the bottom of the plastic flooring piece and scrapes off the excess coating. The excess coating gathers along the inclined surface of the support plate 15 and flows into the collection and dispensing trough 2 through the through hole. When it flows through the filter screen 17, the impurities are filtered and intercepted.

[0041] After coating and excess paint recycling, the plastic flooring parts are conveyed to the drying area of ​​the UV drying unit 8. The UV drying unit 8 is activated to quickly cure and dry the paint. The dried plastic flooring parts are then conveyed to the subsequent processing steps.

[0042] During the processing, the filter screen 17 can be periodically removed for cleaning to ensure that the paint recycling channel is unobstructed.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
