DETAILED DESCRIPTION
[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0025] like Figures 1 to 7 As shown, the utility model provides a coating device for leather production, including a coating mechanism 100 and a drying mechanism 200, the coating mechanism 100 includes a conveying channel 110 and an output channel 120, a coating frame 130 is provided at the end of the conveying channel 110, a coating tank 140 is provided at the top of the coating frame 130, a coating hole 150 is opened at the bottom of the coating tank 140 and two parallel cloth rollers 160 are provided below, the coating hole 150 is provided above the position between the two cloth rollers 160, the output channel 120 is provided at the rear end of the cloth roller 160 and a first steering roller 170 is provided at the end, a scraper 180 is provided on the outside of the first steering roller 170, and the drying mechanism 200 is provided below the coating mechanism 100 and a conveying roller group is provided inside.
[0026] The conveying channel 110 is used to convey the cloth base to the cloth roller 160, and the output channel 120 is used to output the coated cloth base from the coating mechanism 100. The paint is contained in the paint tank 140 and flows out from the coating hole 150 at the bottom of the paint tank 140. The cloth conveyed from the conveying channel 110 crosses through the two cloth rollers 160, and the paint falls between the two cloth rollers 160 and falls on the cloth base. After passing through the output channel 120, the cloth base is conveyed to the first turning roller 170, and the scraper 180 scrapes off the excess paint on the cloth base and flattens the paint on the cloth base. After being conveyed by the first turning roller 170, the cloth base turns to enter the drying mechanism 200 and is dried under the conveyance of the conveying roller group.
[0027] refer to Figure 3The coating hole 150 is opened on one side of the bottom of the coating groove 140 , and a guide plate 190 is provided below the coating hole 150 to ensure that the coating accurately falls between the two rolling rollers 160 .
[0028] refer to Figure 4 The drying mechanism 200 includes a drying body 210, in which a receiving plate 220, a plurality of first conveying rollers 250 and an adjusting roller 260 are provided. The receiving plate 220 is arranged below the plurality of first conveying rollers 250, a collecting trough 230 is provided at the end of the receiving plate 220, the plurality of first conveying rollers 250 are arranged along the length direction of the drying body 210, and the adjusting roller 260 is arranged at the rear end of the first conveying roller 250 at the end.
[0029] The drying body 210 includes not only a mechanical housing but also a heating component. Figure 1 The receiving plate 220 is arranged below the scraper 180, and the paint scraped off by the scraper 180 will directly fall on the receiving plate 220. The paint dripping from the cloth base during the drying process will also fall on the receiving plate 220, and the paint on the receiving plate 220 will eventually gather in the collecting tank 230 and be collected at the position of the collecting tank 230. After the first turning roller 170 turns, the cloth base enters the drying mechanism 200, and the cloth base is tightened by the first turning roller 170 and the adjusting roller 260, and is transported and dried along the multiple first conveying rollers 250.
[0030] refer to Figure 5 The drying mechanism 200 further includes a plurality of second conveying rollers 270 , which are disposed below the receiving plate 220 and are arranged along the length direction of the drying body 210 .
[0031] Most of the cloth base has been dried during the conveying process above the receiving plate 220. When the cloth base reaches the adjusting roller 260, no more paint will drip from it. At this time, the cloth base turns through the adjusting roller 260 and crosses up and down to enter multiple second conveying rollers 270. After the cloth base passes through the second conveying rollers 270, it is sent back to the end that just entered the drying mechanism 200, and can directly enter the next process, saving production space. At the same time, in the final drying process, the paint on the surface of the cloth base is evenly pressed by the second conveying rollers 270, and the coating is more uniform.
[0032] Furthermore, the plurality of second conveying rollers 270 are arranged at an angle and are inclined along the length direction of the drying body 210. The plurality of second conveying rollers 270 are arranged at an angle, and the height of the cloth base is gradually increased during the conveying process, which is convenient for entering the next process. At the same time, the cloth base can be tightened during the conveying process, making it easier to convey.
[0033] refer to Figure 6The receiving plate 220 is tilted and tilted along the length direction of the drying body 210. The paint on the receiving plate 220 can easily flow into the collecting tank 230 under the action of gravity, and a flow outlet 240 is provided on one side of the collecting tank 230.
[0034] Furthermore, the plurality of first conveying rollers 250 are arranged to be tilted, and the tilting direction thereof is consistent with the tilting direction of the receiving plate 220 .
[0035] refer to Figure 2 The conveying channel 110 includes a conveying frame 111 and a plurality of third conveying roller groups arranged on the conveying frame 111. The third conveying roller groups include a plurality of third conveying rollers 112 arranged in parallel and a pressing roller 113 arranged above the third conveying roller 112. The height of the third conveying roller 112 is greater than the height of the cloth rolling roller 160.
[0036] Since the height of the third conveying roller 112 is greater than that of the cloth rolling roller 160, when the paint falls between the two cloth rolling rollers 160, the paint will not flow back to the third conveying roller 112, and can smoothly remain on the cloth base of the cloth rolling roller 160. The pressing roller 113 and the third conveying roller 112 are used in conjunction to ensure smooth conveyance of the cloth.
[0037] Furthermore, the output channel 120 includes an output frame 121 and a plurality of output rollers 122 disposed on the conveying frame 111 .
[0038] Furthermore, a plurality of output rollers 122 are arranged to be tilted downward along the output direction of the output channel 120, and the first turning roller 170 is arranged below and behind the last output roller 122. The height of the cloth base is gradually reduced during the process of being output from the coating mechanism 100, which is conducive to the cloth base smoothly entering the drying mechanism 200 below the coating mechanism 100.
[0039] refer to Figure 7 The coating device also includes a feeding mechanism 300, which includes a storage box 310 and a feed pipe 320. The height of the storage box 310 is greater than the height of the coating tank 140. One end of the feed pipe 320 is connected to the storage box 310, and the other end is provided with a buffer sleeve 330 and inserted into the coating tank 140.
[0040] The paint can flow into the paint tank 140 under the action of gravity without the need for power delivery. It is only necessary to adjust the outflow speed of the paint. A regulating valve 340 can be provided at the discharge port of the storage box 310 or the top of the delivery pipe 320. The paint in the delivery pipe 320 flows into the paint tank 140 through the buffer sleeve 330. Since the paint has a certain potential energy when it falls from a high place, the buffer sleeve 330 can buffer the falling paint to prevent the paint from splashing out of the paint tank 140.
[0041] Working principle: put the coating into the storage box 310, adjust the regulating valve 340, the coating enters the feeding pipe 320 from the storage box 310, and continuously falls into the coating tank 140; then, the coating falls out from the coating hole 150, and falls between the two cloth rollers 160 under the guidance of the guide plate 190; at the same time, the cloth base conveyed by the pressing roller 113 and the third conveying roller 112 enters the two cloth rollers 160, the coating falls on the cloth base, and then the cloth base is conveyed to the first turning roller 170 through the output roller 122, and the scraper 180 continuously scrapes the first turning roller 170. The paint on the cloth base on the roller 170 is scraped off and falls on the receiving plate 220. After the cloth base passes through the first turning roller 170, it is transported and dried by multiple first conveying rollers 250. During the drying process, the paint dripping will also fall on the receiving plate 220. The paint on the receiving plate 220 is finally collected at the collecting groove 230 or dried on the receiving plate 220. Thereafter, the cloth base is turned by the adjusting roller 260, cross-entered into multiple second conveying rollers 270 up and down, further dried and flattened, and finally sent out from the end that has just entered the drying, and enters the next process.
[0042] The drying mechanism 200 of the utility model is arranged below the coating mechanism 100. Only by increasing the height of the entire device, the floor area of the factory building can be greatly reduced, saving factory space. When multiple coating devices are used together, the production speed can be greatly accelerated.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
