Description

Technical Field

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

[0002] Coating machines are mainly used for surface coating processes on films, paper, etc. This machine coats a roll of substrate with a specific functional adhesive, paint, or ink, and then rewinds it after drying. It uses a dedicated multi-functional coating head to achieve various forms of surface coating. Both the unwinding and rewinding of the coating machine are equipped with a full-speed automatic film splicing mechanism, and the tension is automatically controlled by a PLC program in a closed-loop manner. However, some existing coating machines use paints that are not evenly mixed, producing particles that damage the process and the workpiece, increasing costs and reducing production efficiency.

[0003] As disclosed in Chinese Patent Publication No. CN211611936U, a filtration device for a coating machine is used. In operation, coating is added to the coating tank through the inlet. A stirring motor rotates the stirring shaft, causing the stirring blades to stir within the coating tank. A pump then pumps the coating from the tank into a mixing tank. Simultaneously, a sedimentation tank is formed between the baffle and the mixing tank. The settled coating is filtered through filter cotton and then through a high-grade filter plate for final filtration. Upon completion, a waste pump extracts the settled particles from the sedimentation tank, the first filter tank, and the second filter tank via a waste pipe. The coating containing the particles is then pumped back into the coating tank through a discharge pipe. A switch valve prevents the particles from flowing between the sedimentation tank and the first and second filter tanks. Filter cotton and filter cotton slots interlock for easy replacement, as do high-grade filter plates. All electrical inputs in this device are electrically connected to an external power source.

[0004] However, the filtration device of the coating machine in the above application requires cleaning of the paint tank after filtering a type of paint and when it is necessary to clean the paint tank to replace it with other colors of paint. The cleaning of this device is relatively troublesome, so it has certain limitations.

[0005] Therefore, we urgently need to provide a filtration device for coating machines. Utility Model Content

[0006] The purpose of this utility model is to provide a coating machine filtration device to solve the problem mentioned in the background art that after filtering a coating, the coating tank needs to be cleaned after use and when changing to other colors of coating, and the cleaning of the coating tank is relatively troublesome.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a coating machine filtration device, comprising a mixing box and support legs, wherein the four support legs are respectively fixedly connected to the four corners of the lower surface of the mixing box, a mixing device is provided inside the mixing box, and a filtration device is provided at the bottom of the mixing box.

[0008] The mixing device includes a mixing mechanism and a cleaning mechanism. The mixing mechanism is located inside the mixing chamber, and the cleaning mechanism is located above the mixing mechanism.

[0009] The mixing mechanism includes a feed hopper, a mixing motor, a stirring shaft, and mixing plates. The feed hopper is fixedly connected to the left side of the upper surface of the mixing chamber. The mixing motor is installed at the center of the upper surface of the mixing chamber. The top of the stirring shaft is connected to the output end of the mixing motor, and its bottom extends into the interior of the mixing chamber. Two sets of mixing plates are fixedly connected vertically and equidistantly to the outer surface of the stirring shaft. The mixing motor drives the stirring shaft to rotate, which in turn drives the mixing plates to rotate, thereby fully mixing the paint inside the mixing chamber and avoiding uneven color mixing of the paint, which would affect the subsequent coloring.

[0010] A further improvement is that the mixing plates are fixedly connected to the outer surface of the stirring shaft in a ring of three, and each mixing plate has uniformly opened turbulence holes on its outer surface. During the rotation of the mixing plates, the turbulence holes cut and turbulent the paint liquid inside the mixing box, so as to better mix the paint color evenly.

[0011] A further improvement is that the cleaning mechanism includes a connecting ring, a connecting rod, and a scraper. The two connecting rings are respectively fixedly connected to the upper and lower sides of the outer surface of the stirring shaft. The two sets of connecting rods are respectively fixedly connected to the left and right sides of the connecting rings in pairs. The two scrapers are respectively fixedly connected to the outer ends of the two sets of connecting rods. When the paint is mixed and discharged, and it is necessary to change to another color of paint, a cleaning agent is added to the inside of the mixing tank. The stirring shaft drives the scraper to rotate, thereby cleaning the inner wall of the mixing tank and avoiding paint residue that would affect the color of the next paint application.

[0012] A further improvement is that the filtration device includes a connecting mechanism and a filtering mechanism, wherein the connecting mechanism is located at the bottom center of the mixing tank, and the filtering mechanism is located inside the connecting mechanism.

[0013] The connecting mechanism includes a threaded pipe, a filter box, a filter housing, and a pull ring. The threaded pipe is threadedly connected to the bottom center of the mixing box, the filter box is fixedly connected to the bottom of the threaded pipe, the filter housing is disposed inside the filter housing, and the pull ring is fixedly connected to the front center of the filter housing.

[0014] A further improvement is that a threaded hole is provided at the bottom center of the mixing box, and a corresponding external thread is provided at the top of the threaded tube. The two are threadedly connected. A sliding groove is provided on the front of the filter box, and the filter box is slidably connected inside the sliding groove. After the filter box has been used for a long time, the filter box can be removed for cleaning by pulling the pull ring.

[0015] A further improvement is that the filtration mechanism includes a first filter plate, a filter sponge, and a second filter plate. The first filter plate is installed inside the upper part of the filter box, the filter sponge is placed in the center inside the filter box, and the second filter plate is fixedly connected to the bottom of the filter box. The three work together to perform multiple filtrations on the paint liquid, preventing residual particles in the paint liquid from being used for fabric coloring, which would lead to uneven coloring of the fabric and affect the quality of the finished product.

[0016] A further improvement is that filter holes are provided on the upper surfaces of both the first and second filter plates, and the diameter of the filter holes on the first filter plate is larger than that on the second filter plate, thus achieving layered filtration and screening to better filter the paint particles in the paint liquid.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The coating machine's filtration device uses a mixing mechanism to thoroughly stir and mix the paint inside the mixing tank, preventing uneven color mixing that could affect subsequent coloring.

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.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] Example 1:

[0028] A coating machine filtration device includes a mixing box 1 and four support legs 2. The four support legs 2 are respectively fixedly connected to the four corners of the lower surface of the mixing box 1. A mixing device is provided inside the mixing box 1, and a filtration device is provided at the bottom of the mixing box 1.

[0029] The mixing device includes a mixing mechanism, which is located inside the mixing chamber 1.

[0030] The mixing mechanism includes a feed hopper 301, a mixing motor 302, a stirring shaft 303, and mixing plates 304. The feed hopper 301 is fixedly connected to the left side of the upper surface of the mixing box 1. The mixing motor 302 is installed at the center of the upper surface of the mixing box 1. The top of the stirring shaft 303 is connected to the output end of the mixing motor 302, and its bottom extends into the interior of the mixing box 1. Two sets of mixing plates 304 are fixedly connected vertically and equidistantly to the outer surface of the stirring shaft 303. The mixing motor 302 drives the stirring shaft 303 to rotate, which in turn drives the mixing plates 304 to rotate, thereby fully mixing the paint inside the mixing box 1 and avoiding uneven color mixing of the paint, which would affect the subsequent coloring.

[0031] The mixing plates 304 are fixedly connected to the outer surface of the stirring shaft 303 in a ring of three, and each mixing plate 304 has uniformly opened turbulence holes on its outer surface. During the rotation of the mixing plates 304, the turbulence holes cut and turbulent the paint liquid inside the mixing box 1, so as to better mix the paint color evenly.

[0032] The filtration device includes a connecting mechanism and a filtering mechanism. The connecting mechanism is located at the bottom center of the mixing box 1, and the filtering mechanism is located inside the connecting mechanism.

[0033] The connecting mechanism includes a threaded pipe 401, a filter box 402, a filter housing 403, and a pull ring 404. The threaded pipe 401 is threadedly connected to the bottom center of the mixing box 1. The filter box 402 is fixedly connected to the bottom of the threaded pipe 401. The filter housing 403 is disposed inside the filter housing 402. The pull ring 404 is fixedly connected to the front center of the filter housing 403.

[0034] A threaded hole is provided at the bottom center of the mixing box 1, and a corresponding external thread is provided at the top of the threaded tube 401. The two are threadedly connected. A sliding groove is provided on the front of the filter box 402, and the filter box 403 is slidably connected inside the sliding groove. After the filter box 403 has been used for a long time, the filter box 403 can be taken out for cleaning by pulling the pull ring 404.

[0035] The filtration mechanism includes a first filter plate 405, a filter sponge 406, and a second filter plate 407. The first filter plate 405 is installed inside the upper part of the filter box 403, the filter sponge 406 is placed in the center inside the filter box 403, and the second filter plate 407 is fixedly connected to the bottom of the filter box 403. The three work together to perform multiple filtrations on the paint liquid, preventing residual particles in the paint liquid from being used for fabric coloring, which would lead to uneven coloring of the fabric and affect the quality of the finished product.

[0036] The upper surfaces of the first filter plate 405 and the second filter plate 407 are both provided with filter holes, and the diameter of the filter holes on the first filter plate 405 is larger than the diameter of the filter holes on the second filter plate 407. This layered filtration and screening process allows for better filtration of paint particles in the paint liquid.

[0037] In use, the paint raw materials and water are first poured into the mixing box 1 through the feed hopper 301. Then, the mixing motor 302 is started, which drives the stirring shaft 303 to rotate, thereby driving the mixing plate 304 on the stirring shaft 303 to rotate, so that the paint raw materials and water are fully mixed. The turbulence holes on the mixing plate 304 cut and turbulent the paint liquid inside the mixing box 1, so that the paint color is better mixed evenly. The evenly mixed paint liquid enters the filter box 402 through the threaded pipe 401. The first filter plate 405 inside the filter box 403 intercepts the paint particles with larger diameters in the paint liquid. The intercepted paint liquid enters the filter sponge 406, which intercepts the remaining particles in the paint liquid again. The purer paint liquid drips from the filter sponge 406 onto the second filter plate 407 for a third filtration, so as to maximize the filtration of the paint liquid and prevent the residual particles in the paint liquid from being used for fabric coloring, which would cause uneven coloring of the fabric and affect the quality of the finished product.

[0038] Example 2

[0039] Based on Embodiment 1, the mixing device also includes a cleaning mechanism, which is disposed on the mixing mechanism. The cleaning mechanism includes a connecting ring 305, a connecting rod 306, and a scraper 307. Two connecting rings 305 are respectively fixedly connected to the upper and lower sides of the outer surface of the stirring shaft 303. Two sets of connecting rods 306 are respectively fixedly connected to the left and right sides of the connecting rings 305 in pairs. Two scrapers 307 are respectively fixedly connected to the outer ends of the two sets of connecting rods 306.

[0040] After the paint is mixed and discharged, when it is necessary to change to another color of paint, a cleaning agent is added inside the mixing tank 1. The stirring shaft 303 drives the connecting ring 305 and the connecting rod 306 on it to rotate, which in turn drives the scraper 307 to rotate, thereby cleaning the inner wall of the mixing tank 1 and avoiding paint residue that would affect the color of the next paint application.
