It uses a special multi-functional coating head to achieve various forms of surface coating. The unwinding and rewinding of the coating machine are equipped with a full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control. Throughout the process, the coating material in a flowing state is continuously consumed. The coating material will not all adhere to the floor; there will always be some coating material flowing to a lower position in the equipment, resulting in waste of coating material and increased cost.

[0003] The key technical features of the coating liquid recovery tank device for an automated coating machine, as disclosed in Chinese Patent Announcement No. CN222174690U, are as follows: It includes a support base; a collection plate has multiple return holes fixedly opened on its surface; guide plates are fixedly installed on both sides of the top of the collection plate; one side of the guide plate is fixedly connected to the inner wall of the support base; a return plate is fixedly installed on the inner side of the support base; the center of the top of the return plate is raised upwards; and the return plate is located below the collection plate.

[0004] In the above scheme, the dripping coating liquid is recovered by the cooperation of the collection plate, return hole, guide plate, return plate, guide groove, guide roller and collection groove. However, it has the following disadvantages: the device cannot intercept and filter impurities in the coating liquid during use, resulting in a reduction in the quality of the recovered coating liquid. Utility Model Content

[0005] The purpose of this invention is to provide a coating liquid recovery mechanism for a coating machine, so as to solve the problem that the device cannot intercept and filter impurities in the coating liquid during use, resulting in a decrease in the quality of the recovered coating liquid.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a coating liquid recovery mechanism for a coating machine, comprising a collection plate, the collection plate being fixed inside a support base, the top surface of the collection plate having several return holes, the top surface of the collection plate being inclined at both sides towards the center, a coating assembly being provided on the top of the support base, two guide rollers being provided on the top of the support base, a filter frame being detachably provided inside the support base, the filter frame being located on the bottom surface of the collection plate, a filter screen being fixed inside the filter frame, a return plate being fixed inside the support base, the return plate being located below the filter frame, the surface of the return plate being inclined at both sides and the center, two guide grooves being provided on the top surface of the return plate, and a collection box being fixed on the bottom surface of the return plate.

[0007] Preferably, a connecting plate is fixed inside the support base, and an electric push rod is fixed to the rear side of the connecting plate. One end of the telescopic rod of the electric push rod passes through the connecting plate and is fixed with a scraper. The bottom of the scraper is in contact with the surface of the collecting plate.

[0008] Preferably, a limiting hole is provided on one side of the connecting plate, and a limiting post is slidably inserted into the limiting hole. The front end of the limiting post is fixedly connected to the rear side of the scraper.

[0009] Preferably, the outer wall of the filter frame has two threaded grooves on the left and right sides respectively, and the outer wall of the support base has two threaded holes on the left and right sides respectively. Bolts are threaded into the two threaded holes respectively, and the threaded ends of the two bolts are threaded into the two threaded grooves respectively.

[0010] Preferably, positioning strips are fixed on the left and right sides of the outer wall of the filter frame, and positioning grooves are opened on the left and right sides of the inner wall of the support base, with the two positioning grooves respectively positioning the two positioning strips.

[0011] Preferably, a baffle is fixed at the rear end of the reflux plate.

[0012] Compared with the prior art, the coating liquid recovery mechanism of a coating machine that adopts the above technical solution has the following beneficial effects:

[0013] 1. In use, the combined use of the collection plate, return hole, filter frame, filter screen, return plate, guide groove and collection box facilitates the filtration and recovery of coating liquid dripping from the guide roller, improves the quality of the recovered coating liquid, and facilitates subsequent reuse.

[0014] Second, during use, the electric push rod allows the scraper to move back and forth, thereby scraping off the residual coating liquid on the collection plate and directing it into the collection box, reducing waste of coating liquid. The use of the limiting hole and limiting post effectively limits the scraper, ensuring it does not deviate or wobble, thus guaranteeing the stability and accuracy of the scraper during movement.

[0015] Thirdly, during use, the combination of threaded grooves, threaded holes, and bolts facilitates the disassembly and assembly of the filter frame and filter screen, making it easy to clean or replace them. The combination of positioning strips and positioning grooves aids in the positioning of the filter frame during installation, facilitating alignment of the threaded grooves and threaded holes, thus improving installation convenience. The baffle helps to block the coating liquid, preventing it from flowing out from the rear end of the return plate. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3As shown, a coating liquid recovery mechanism for a coating machine includes a collection plate 1, which is fixed inside a support base 2. The top surface of the collection plate 1 has several return holes 3. The top surface of the collection plate 1 is sloped towards the center on both sides. A coating assembly 4 is provided on the top of the support base 2. The coating assembly 4 is a prior art structure, and reference can be made to Chinese Patent Publication No. CN222174690U. The coating assembly 4 in this application is the same as the coating assembly in the referenced document. Two guide rollers 5 are provided on the top of the support base 2. The guide rollers 5 are a prior art structure, and reference can be made to... The Chinese patent application with patent number CN222174690U discloses a guide roller 5, which is the same guide roller mentioned in the referenced document. A filter frame 6 is detachably installed inside the support base 2. The filter frame 6 is located on the bottom surface of the collection plate 1. A filter screen 7 is fixed inside the filter frame 6. A return plate 8 is fixed inside the support base 2. The return plate 8 is located below the filter frame 6. The two sides and the center of the surface of the return plate 8 are sloped. The return plate 8 is set in an inclined state. Two guide grooves 9 are opened on the top surface of the return plate 8. A collection box 10 is fixed on the bottom surface of the return plate 8.

[0023] During use, when the liquid coating material flows out from the bottom and sides of the guide roller 5, the coating liquid on the guide roller 5 drips onto the surface of the collection plate 1. The coating liquid flows towards the center along the slope of the collection plate 1. When the coating liquid passes through the return hole 3, it flows down to the surface of the filter screen 7 inside the filter frame 6, which can intercept and filter impurities in the coating liquid. After being filtered by the filter screen 7, the coating liquid continues to flow down to the surface of the return plate 8 through the filter holes. The coating liquid will disperse and flow to both sides on the surface of the return plate 8, and then converge into the interior of the guide groove 9. Due to the inclined effect of the return plate 8, it finally flows into the collection box 10 for storage, which is convenient for subsequent use. Through the coordinated use of the collection plate 1, return hole 3, filter frame 6, filter screen 7, return plate 8, guide groove 9 and collection box 10, the coating liquid dripping from the guide roller 5 is filtered and recovered, improving the quality of the recovered coating liquid and facilitating subsequent reuse.

[0024] like Figures 1-4 As shown, a connecting plate 11 is fixed inside the support base 2, and an electric push rod 12 is fixed to the rear side of the connecting plate 11. One end of the telescopic rod of the electric push rod 12 passes through the connecting plate 11 and is fixed with a scraper 13. The bottom of the scraper 13 is in contact with the surface of the collecting plate 1.

[0025] In use, by activating the electric push rod 12, the scraper 13 can move back and forth, thereby scraping off the coating liquid remaining on the collection plate 1 and allowing it to flow into the collection box 10, reducing the waste of coating liquid.

[0026] like Figures 1-4As shown, a limiting hole 14 is provided on one side of the connecting plate 11. A limiting post 15 is slidably inserted into the limiting hole 14. The front end of the limiting post 15 is fixedly connected to the rear side of the scraper 13. Two threaded grooves 16 are provided on the left and right sides of the outer wall of the filter frame 6. Two threaded holes 17 are provided on the left and right sides of the outer wall of the support base 2. Bolts 18 are threaded into the two threaded holes 17 respectively. The threaded ends of the two bolts 18 are threaded into the two threaded grooves 16 respectively.

[0027] During use, the cooperation of the limiting hole 14 and the limiting post 15 helps to limit the scraper 13, ensuring that the scraper 13 will not deviate or shake, thus guaranteeing the stability and accuracy of the scraper 13 during movement. The cooperation of the threaded groove 16, threaded hole 17 and bolt 18 facilitates the disassembly and assembly of the filter frame 6 and filter screen 7 by the operator, thereby making it easy to clean or replace the filter frame 6 and filter screen 7.

[0028] like Figures 1-3 As shown, positioning strips 19 are fixed on the left and right sides of the outer wall of the filter frame 6, and positioning grooves 20 are opened on the left and right sides of the inner wall of the support base 2. The two positioning grooves 20 respectively position the two positioning strips 19, and a baffle 21 is fixed at the rear end of the return plate 8.

[0029] In use, the positioning strip 19 and the positioning groove 20 work together to assist the operator in positioning the filter frame 6 during installation, making it easier to align the threaded groove 16 with the threaded hole 17, thus improving the convenience of installation. The baffle 21 helps to block the coating liquid and prevent it from flowing out from the rear end of the return plate 8.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
