Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wall sticker coating, in particular to a decorative wall sticker coating machine. BACKGROUND

[0002] Wall stickers are widely used in home decoration, commercial space layout and other scenes due to their convenient installation and various styles. The quality of wall stickers depends largely on the quality of the coating process. The coating process not only needs to ensure that the coating thickness meets the design requirements, but also needs to ensure that the coating is evenly distributed to achieve good decorative effect and durability. However, the traditional coating process has many technical pain points and cannot meet the production needs of high-quality wall stickers.

[0003] For example, the traditional coating roller method directly coats the coating on the surface of the wall sticker with a coating roller, which causes uneven thickness and uneven surface; For example, in the traditional nozzle coating method, the flowability and viscosity of the coating are extremely strict. When the coating has high viscosity or contains small particles, the nozzle is easily blocked, which not only affects the continuity of the coating, but also increases the frequency of equipment cleaning and maintenance, and easily causes local accumulation, coating leakage or uneven thickness. Especially when coating a large area, such differences will be more obvious. Secondly, the core component of the nozzle coating equipment is the nozzle structure, which is precise. Once blocked or damaged, the replacement cost is high, and cleaning the nozzle requires special cleaning agents and complex processes, which is time-consuming and labor-intensive.

[0004] The traditional technology uses a scraper to remove excess coating on the wall sticker to control the coating thickness. It pays excessive attention to thickness control and lacks control over the uniformity of the coating on the surface of the wall sticker, often causing uneven coating thickness and uneven surface, which seriously affects the decorative effect of the wall sticker.

[0005] Therefore, a decorative wall sticker coating machine is provided, which coats the coating with a predetermined width and thickness by pre-flat coating, then transfers the coating to the surface of the wall sticker by a coating roller, and realizes the coating of the wall sticker with a predetermined thickness and width by a secondary leveling process.

[0030] Furthermore, in order to realize the convenient adjustment of the double-end screw rod 501, one end of the double-end screw rod 501 is fixedly installed with a turntable 507, it is necessary to illustrate that, in order to avoid the change of the interval of the two limiting plates 502 after the interval adjustment is completed due to the movement of the double-end screw rod 501, a convenient positioning structure is arranged on the second mounting frame, that is, the position of the double-end screw rod 501 is fixed by the mode that the slide plate is pushed to extrude and position the turntable 507 through the bolt, specifically, the convenient positioning structure adopts a U-shaped head design, the turntable 507 and the slide plate are arranged in the U-shaped head, the bolt is threadedly installed on the outside of the U-shaped head and penetrates into the inside of the U-shaped head, and then the bolt is rotatably connected with one side of the slide plate through a bearing, when positioning, the other side of the slide plate matches the inner cavity of the U-shaped head to extrude and position the turntable 507.

[0031] The paint on the cloth belt 403 needs to be leveled to ensure uniformity of the coating. In consideration of the flexible adjustment of the paint width, the pre-distributing assembly 4 further comprises two sets of leveling assemblies 404. One set of leveling assemblies 404 is slidingly installed on the top of one side of the two limiting plates 502. The leveling assembly 404 comprises a first scraper plate 4041 and two second scraper plates 4042. The two second scraper plates 4042 are slidingly installed on the front and rear sides of the first scraper plate 4041, respectively. The two second scraper plates 4042 are slidingly installed on the top of the other side of the two limiting plates 502. In this way, when the limiting plates 502 are adjusted in the forward and backward directions, the two second scraper plates 4042 can also be moved. However, the movement of the first scraper plate 4041 is uncertain. In order to ensure controllable movement and height adjustment, the top of the third mounting bracket is fixedly installed with an assembly plate 4046 through two vertical rods 4045. The outer periphery of the two vertical rods 4045 is commonly sleeved and slidingly installed with a bracket 4047. The bottom of the bracket 4047 is fixedly connected with the top of the first scraper plate 4041. The bottom of the assembly plate 4046 is fixedly installed with a first cylinder 4048.

The synchronous movement of the shunt angle plate 4044 is achieved. The paint sprayed by the spray head 305 is quickly shunted, so as to ensure the leveling of the set thickness of the paint in a short stroke and ensure the uniformity of the distribution.

[0033] Further, in order to ensure the uniformity of the distribution of the set thickness of the paint, another set of leveling assemblies 404 is slidingly installed on the top of the other side of the two limiting plates 502.

[0034] When the paint is placed in the paint frame 1 for a long time, it is easy to appear uneven conditions such as precipitation, in order to ensure the uniformity of the paint, the bottom of one side of the inner cavity of the paint frame 1 is provided with a breathing port 101, the inside of the breathing port 101 is slidably installed with a piston plate 102, the front and rear sides of one side of the piston plate 102 are fixedly installed with square groove traction blocks 103, an eccentric push rod 104 is slidably installed between the two square groove traction blocks 103, the front and rear sides of the paint frame 1 are provided with notches 105, the both ends of the eccentric push rod 104 are penetrated through the notches 105 and fixedly installed with a driving disc 107, the front and rear sides of the paint frame 1 are fixedly installed with a plurality of limiting rollers 106, and the plurality of limiting rollers 106 are respectively arranged on the outer periphery of the driving disc 107, so that only the driving disc 107 is driven to rotate, the eccentric push rod 104 can drive the square groove traction blocks 103 to reciprocate left and right, and then the square groove traction blocks 103 drive the piston plate 102 to breathe the paint in the breathing port 101 to push the paint, so as to ensure the uniformity of the paint.

Example 2

[0036] As an improvement of the last embodiment, the wall decoration coating machine is improved. In order to ensure the uniformity of the coating thickness on the wall decoration, the leveling assembly 7 is used for the secondary leveling treatment of the wall decoration coated with the coating. The leveling assembly 7 includes a second cylinder 701 and a positioning square rod 702. The telescopic end of the second cylinder 701 is fixedly installed with a push frame 703. The push frame 703 is fixedly installed with a scraping piece 704 through bolts. A guide roller 202 is used in cooperation with the scraping piece 704. Through the telescopic extension of the second cylinder 701, the distance between the scraping piece 704 and the wall decoration can be adjusted to achieve the purpose of controlling the uniformity of the coating thickness of the wall decoration. Further, the top of the positioning square rod 702 is fixedly connected with a receiving plate frame 705 and an overflow hopper 706 through bolts. The overflow hopper 706 is arranged directly below the scraping piece 704 to receive and transport the excess coating back to the coating frame 1. At this time, it needs to be noted that according to the actual needs, if the coating in the overflow hopper 706 is mixed with impurities on the wall decoration, a small bucket for receiving materials is hung at both ends of the overflow hopper 706 to avoid pollution of the coating in the coating frame 1. The second cylinder 701 is fixedly installed on the top of the receiving plate frame 705. The top of the limiting plate 502 is slidably installed with a support plate 7011. The positioning square rod 702 penetrates through the two support plates 7011 and is slidably connected with the two support plates 7011. At this time, the two support plates 7011 realize the left and right movement limiting of the positioning square rod 702. That is, the positioning square rod 702 needs to move left and right, which must drive the support plate 7011 to move left and right. The top of the assembly plate 4046 is also fixedly installed with two guide plates 707. The receiving plate frame 705 is slidably installed between the two guide plates 707. The top of the two guide plates 707 is fixedly installed with a cover plate 708 through bolts. At this time, the front and rear displacement limiting of the receiving plate frame 705 is realized. The bottom of the assembly plate 4046 is rotatably installed with a toothed roller 709 through two connecting frames. The top of the support 4047 is fixedly installed with a first toothed plate 7010. One side of the support plate 7011 is fixedly installed with a second toothed plate 7012. The first toothed plate 7010 and the second toothed plate 7012 are engaged with the toothed roller 709. The structure here is used to match the coating thickness required by wall decorations of different thicknesses. Specifically, when the thickness of the coating on the coating belt 403 needs to be adjusted, the first cylinder 4048 needs to drive the support 4047 to ascend and descend. At this time, the first toothed plate 7010 will move up and down, which will drive the toothed roller 709 to rotate, and then the second toothed plate 7012 will drive the support plate 7011 to move. At this time, the support plate 7011 drives the positioning square rod 702 to move, which realizes the synchronous adjustment of the distance between the scraping piece 704 and the wall decoration. It is relatively convenient to use.
