Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper processing technology, specifically a double-sided synchronous rotary spraying machine. Background Technology
[0002] In the paper processing industry, spray coating is a crucial surface treatment technology. By spraying the paper surface, various special physical properties and aesthetic effects can be imparted, such as enhancing the paper's water resistance, abrasion resistance, and anti-aging properties, or providing specific colors, textures, and gloss levels. This treatment not only significantly increases the added value of paper products, meeting the demands of high-end printing, packaging decoration, and specialty papers, but also expands the application range of paper, making it suitable for book covers, gift packaging, advertising materials, and other occasions where high visual appeal and durability are required.
[0003] However, existing paper coating equipment and technologies still have some significant limitations. Traditional coating methods often employ single-sided operation, requiring one side to be coated and dried before processing the other. This intermittent operation is not only inefficient but also prone to misalignment of the front and back patterns due to positioning errors between coating sessions. Furthermore, common fixed nozzles or simple reciprocating coating mechanisms struggle to ensure uniform coating distribution on the paper surface, easily resulting in defects such as runs, orange peel texture, or uneven thickness. Therefore, we propose a double-sided synchronous rotary coating machine. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a double-sided synchronous rotary spraying machine that can realize synchronous rotary spraying of paper on both sides, improve the uniformity of spraying and production efficiency, and adapt to the processing of paper of different thicknesses, which can effectively solve the problems in the background art.

[0015] The working principle of the double-sided synchronous rotary spraying machine provided by this utility model is as follows: First, the operator feeds the paper to be sprayed into the opening on one side of the mounting box 1, and it is conveyed by the guide components 8 on the left and right sides. Specifically, the second motor 85 starts and drives the upper guide roller 82 to rotate. Through two meshing gears 83, the two guide rollers 82 rotate synchronously in opposite directions, thereby clamping and pulling the paper smoothly into the spraying area. Then, according to the thickness of the paper to be processed, the two hydraulic rods 41 are activated by the external control switch group. The telescopic arms of the hydraulic rods 41 drive the connecting strip 42 to move, thereby adjusting the distance between the upper and lower guide barrels 44 and the spraying components 5 on them to accommodate different thicknesses. The paint is supplied through the feeding component 6. Specifically, the external feeding pipeline is connected to the slide pipe 61 through the connecting flange ring 62. The paint flows into the continuously rotating guide barrel 44 through the slide pipe 61 and is further distributed to the four connecting barrels 51. Finally, it is evenly distributed. The evenly distributed nozzles 52 spray out the coating; at the same time, the rotating assembly 7 provides rotational power, the first motor 72 starts and drives the upper connecting plate 74 to rotate, which in turn drives the hexagonal prism 73 to rotate. Since the hexagonal holes in the middle of the two rotating tubes 43 are slidably connected to the hexagonal prism 73, the rotation of the hexagonal prism 73 can synchronously drive the two rotating tubes 43 to rotate together; each rotating tube 43 transmits power to the sprocket ring 45 on the same side of the guide barrel 44 through the sprocket ring 45 and chain 46, thereby driving the guide barrel 44 and the connecting barrel 51 and nozzles 52 fixed thereon to rotate together; thus, as the paper passes through at a uniform speed, its upper and lower surfaces are evenly covered by the coating sprayed by the two sets of high-speed rotating nozzles 52, realizing efficient double-sided synchronous rotating spraying; during the spraying process, the transparent baffle 3 installed in front can prevent the coating from splashing and facilitate the observation of the internal working conditions; the paper that has been sprayed is finally sent out from the opening on the other side of the mounting box 1 and enters the subsequent drying and other processes.
[0016] It is worth noting that the external control switch group disclosed in the above embodiments is equipped with buttons that correspond one-to-one with the hydraulic rod 41, the first motor 72 and the second motor 86. The hydraulic rod 41, the first motor 72 and the second motor 86 can be freely configured according to the actual application scenario. The external control switch group controls the operation of the hydraulic rod 41, the first motor 72 and the second motor 86 using methods commonly used in the prior art.
