Description

Technical Field

[0001] This invention relates to the field of coating production equipment technology, and more specifically, to a planar uniform coating device for a production line. Background Technology

[0002] A coating production unit is a device used to manufacture coating materials. It typically consists of a series of working units and related equipment, used to uniformly apply coatings, glues, or other adhesives onto a substrate. Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, coating, or ink with a specific function, and then dries and rewinds it.

[0003] However, in the coating process of traditional production lines, due to the lack of existing technology, there is a lack of structures that can control the coating thickness of the production line. That is, it is impossible to scrape the coating evenly on the surface of the fabric on the production line, and it is impossible to accurately control the thickness of the coating on the fabric. At the same time, there is a lack of existing technology that can scrape off and collect the excess coating on the fabric, which will cause the coating to overflow and be wasted during the lamination process due to excessive coating on the fabric.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0005] This invention provides a planar uniform coating device for a production line to solve the technical problems mentioned in the background art, namely, the lack of a structure to control the coating thickness of the production line and the lack of a structure to scrape off and collect excess coating on the fabric, which leads to the overflow and waste of coating during lamination due to excessive coating on the fabric.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a planar uniform coating device for a production line, comprising a conveyor table, a conveyor belt on the top of the conveyor table, a fixed-height scraping mechanism and a collection mechanism on the top of the conveyor belt, the fixed-height scraping mechanism being able to drive multiple structures with controllable height positions to move in parallel, thereby controlling the thickness of the coating on the surface of the fabric on the conveyor belt and scraping away excess coating, the collection mechanism being able to receive and collect excess coating by controlling the position of the conveyor belt height.

[0007] In a preferred embodiment, the fixed-height scraping mechanism includes multiple scraper strips arranged in an L-shape on the conveyor belt. The multiple scraper strips are arranged at equal intervals, with their bottoms abutting against the top of the conveyor belt. A common belt strip is fixedly installed on one side of each of the multiple scraper strips. The common belt strip has a ring structure and is arranged perpendicularly to the conveyor belt. Pulleys are rotatably installed on both sides of the common belt strip. Two pulleys are arranged symmetrically to each other, and a rotating shaft is rotatably installed on the inner wall of each of the two pulleys. The two rotating shafts are arranged horizontally.

[0008] In a preferred embodiment, a motor is provided on one side of each of the rotating shafts, the output end of the motor is fixedly connected to one side of the rotating shaft, and a pull plate is rotatably mounted on the outer wall of both rotating shafts. The pull plate is slidably mounted on the top of the conveyor table, the motor is fixedly mounted on the outer wall of the pull plate, and the pull plate is set in a horizontal state.

[0009] In a preferred embodiment, the bottom of the conveyor belt is provided with a plurality of pressure rollers, which are arranged horizontally at equal intervals. The tops of the plurality of pressure rollers are in contact with the bottom of the conveyor belt. Top brackets are rotatably mounted on both sides of the plurality of pressure rollers. The top brackets are fixedly mounted on the top of the conveyor table. The plurality of pressure rollers and a plurality of scraper strips are arranged in cooperation with each other.

[0010] In a preferred embodiment, lifting plates are fixedly installed on both outer walls of the pull strip, the two lifting plates are horizontally arranged, and a positioning box is fixedly installed on one side of the two lifting plates. The positioning box is vertically arranged, and a preliminary positioning plate is slidably installed on the bottom inner wall of the positioning box. The preliminary positioning plate is vertically downward, and a scale line is opened on the outer wall of the preliminary positioning plate. The scale line is configured to cooperate with the bottom outer wall of the positioning box.

[0011] In a preferred embodiment, a positioning roller is rotatably mounted on the bottom of the initial positioning plate, the bottom of the positioning roller is in contact with the top of the conveyor belt, and support rods are fixedly mounted on both sides of the initial positioning plate. Limit blocks are fixedly mounted on one side of each of the two support rods, and the limit blocks are fixedly mounted on the top of the conveyor table. A threaded rotating rod is rotatably mounted on the top of the initial positioning plate, and the threaded rotating rod is threadedly connected to the top of the positioning box. A turntable is fixedly mounted on the top of the threaded rotating rod, and the turntable is set in a horizontal position.

[0012] In a preferred embodiment, the collecting mechanism includes a collecting box disposed on one side of the conveyor belt. The collecting box is fixedly installed on the top of the conveyor table and is arranged horizontally. The collecting box and the scraper strip are arranged parallel to each other. The width of the collecting box is greater than the width of the scraper strip. A guide plate is slidably installed on one inner wall of the collecting box.

[0014] The technical effects and advantages of this invention are as follows: This invention, by setting up a fixed-height scraping mechanism and a collection mechanism, first stabilizes the height of the initial fixed plate with the height of the top of the conveyor belt, and then controls the positioning box to make the belt puller drive two rotating shafts to move synchronously to the required height. The two rotating shafts drive the pulley and the same belt to maintain the height, and the same belt drives multiple scraper strips to maintain the synchronous height. That is, the height of the multiple scraper strips is the height of the coating thickness on the surface of the fabric on the conveyor belt. In this way, multiple scraper strips can sequentially scrape off the excess coating on the surface of the fabric on the conveyor belt, so as to scrape the coating on the surface of the fabric on the production line evenly and precisely control the thickness of the coating on the fabric. At the same time, the support spring supports the clamping plate to move up and make the bottom roller fit against the bottom of the conveyor belt. Then, the clamping plate drives the belt support strip so that the guide plate fills the height difference between the top outer wall of the conveyor belt and the top outer wall of the collection box. Then, the paint scraped by multiple scraper strips on the conveyor belt can slide down and enter the collection box, avoiding the overflow and waste of paint on the fabric during the lamination process due to excessive paint.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Existing technologies lack structures capable of controlling the coating thickness on the production line. Specifically, they cannot evenly spread the coating on the fabric and cannot precisely control the coating thickness. Furthermore, existing technologies lack structures for scraping and collecting excess coating from the fabric, leading to coating overflow and waste during lamination. To address this problem, the following technical solution is proposed: Refer to the instruction manual appendix Figures 1-7 A planar uniform coating device for a production line, such as Figure 1 and Figure 2 As shown, the system includes a conveyor platform 1, a conveyor belt 2 on top of the conveyor platform 1, a fixed-height scraping mechanism 3 and a collection mechanism 4 on top of the conveyor belt 2. The fixed-height scraping mechanism 3 can drive multiple structures with controllable height positions to move in parallel, thereby controlling the thickness of the coating on the surface of the fabric on the conveyor belt 2 and scraping away excess coating. The collection mechanism 4 can receive and collect excess coating by controlling the position of the conveyor belt 2.

[0025] like Figure 3 and Figure 4As shown, the fixed-height scraping mechanism 3 includes multiple scraper strips 31 arranged on the conveyor belt 2. The multiple scraper strips 31 are arranged in an L-shape and are equidistant from each other. The bottom of the multiple scraper strips 31 is in contact with the top of the conveyor belt 2. A belt strip 32 is fixedly installed on one side of the multiple scraper strips 31. The belt strip 32 is arranged in a ring structure and is perpendicular to the conveyor belt 2. Pulleys 33 are rotatably installed on both sides of the belt strip 32. The two pulleys 33 are symmetrically arranged. A rotating shaft 34 is rotatably installed on the inner wall of the two pulleys 33. The two rotating shafts 34 are arranged in a horizontal state. During the rotation and transportation process of the conveyor belt 2, the pulleys 33 are driven to rotate by the two rotating shafts 34. The two pulleys 33 drive the belt strip 32 to rotate synchronously. Then, the belt strip 32 drives multiple scraper strips 31 to scrape the paint on the conveyor belt 2 in sequence.

[0026] like Figure 3 and Figure 4 As shown, a motor 35 is provided on one side of the rotating shaft 34. The output end of the motor 35 is fixedly connected to one side of the rotating shaft 34. The outer walls of the two rotating shafts 34 are rotatably mounted with a pull plate 36. The pull plate 36 is slidably mounted on the top of the conveyor table 1. The motor 35 is fixedly mounted on the outer wall of the pull plate 36. The pull plate 36 is set in a horizontal state. The pull plate 36 drives the rotating shafts 34 on both sides to move synchronously, that is, drives the two rotating shafts 34 to move synchronously to the required height. The motor 35 can start and drive the rotating shafts 34 to rotate, and the rotating shafts 34 drive the pulleys 33 to rotate synchronously with the belt 32.

[0027] like Figure 4 and Figure 5 As shown, the bottom of the conveyor belt 2 is provided with multiple pressure rollers 37, which are arranged horizontally at equal intervals. The tops of the multiple pressure rollers 37 are in contact with the bottom of the conveyor belt 2. Top brackets 38 are rotatably installed on both sides of the multiple pressure rollers 37. The top brackets 38 are fixedly installed on the top of the conveyor table 1. The multiple pressure rollers 37 and multiple scraper strips 31 are arranged in a cooperative manner. The top support 38 drives multiple pressure rollers 37 located at the bottom of the conveyor belt 2.

[0028] like Figure 4 and Figure 5 As shown, lifting plates 39 are fixedly installed on both outer walls of the pull strip 36. The two lifting plates 39 are set in a horizontal state. A positioning box 310 is fixedly installed on one side of the two lifting plates 39. The positioning box 310 is set in a vertical state. A preliminary positioning plate 311 is slidably installed on the bottom inner wall of the positioning box 310. The preliminary positioning plate 311 is set vertically downward. The outer wall of the preliminary positioning plate 311 has scale lines, which are matched with the bottom outer wall of the positioning box 310. The positioning box 310 moves on the initial positioning plate 311, causing the lifting plates 39 on both sides to move synchronously, and the lifting plates 39 on both sides cause the pull strips 36 to move synchronously.

[0029] like Figure 4 and Figure 5 As shown, a positioning roller 312 is rotatably installed on the bottom of the initial positioning plate 311. The bottom of the positioning roller 312 is in contact with the top of the conveyor belt 2. Support rods 313 are fixedly installed on both sides of the initial positioning plate 311. Limit blocks 314 are fixedly installed on one side of each of the two support rods 313. Limit blocks 314 are fixedly installed on the top of the conveyor table 1. A threaded rotating rod 315 is rotatably installed on the top of the initial positioning plate 311. The threaded rotating rod 315 is threadedly connected to the top of the positioning box 310. A turntable 316 is fixedly installed on the top of the threaded rotating rod 315. The turntable 316 is set in a horizontal state. The limiting block 314 drives the support rod 313 to make the initial positioning plate 311 cooperate with the top of the conveyor belt 2, so that the height of the initial positioning plate 311 and the height of the top of the conveyor belt 2 remain stable. By rotating the turntable 316, the threaded rotating rod 315 is driven to control the height of the positioning box 310. The positioning box 310 drives the lifting plate 39 to move synchronously. The positioning roller 312 ensures the stability of the bottom rolling when the initial positioning plate 311 contacts the conveyor belt 2.

[0030] like Figure 6 and Figure 7 As shown, the collection mechanism 4 includes a collection box 41 disposed on one side of the conveyor belt 2. The collection box 41 is fixedly installed on the top of the conveyor table 1. The collection box 41 is horizontally disposed and parallel to the scraper strip 31. The width of the collection box 41 is greater than the width of the scraper strip 31. A guide plate 42 is slidably installed on one inner wall of the collection box 41. The top of the guide plate 42 is sloped. The top outer wall of the guide plate 42 is in close contact with the top outer wall of the conveyor belt 2. The guide plate 42 fills the height difference between the top outer wall of the conveyor belt 2 and the top outer wall of the collection box 41, so that the paint on the conveyor belt 2 can enter the collection box 41 when it slides down.

[0031] like Figure 6 and Figure 7 As shown, a support strip 43 is fixedly installed on one side of the guide plate 42. The support strip 43 is set in a horizontal state. A positioning plate 44 is fixedly installed on one side of the support strip 43. The positioning plate 44 is slidably installed on the outer wall of the collection box 41. The positioning plate 44 is set in a vertical state. A limiting bottom roller 45 is rotatably installed on one side of the outer wall of the positioning plate 44. The limiting bottom roller 45 is set in a horizontal state and is located at the bottom of the conveyor belt 2. The top of the limiting bottom roller 45 is in contact with the bottom of the conveyor belt 2. A support spring 46 is fixedly installed on one side of the outer wall of the positioning plate 44. The support spring 46 is fixedly installed on the outer wall of the collection box 41. The support spring 46 supports the pressing clamping plate 44 to move upward and causes the bottom limiting roller 45 to fit against the bottom of the conveyor belt 2, thereby determining the position of the clamping plate 44. The clamping plate 44 drives the belt support strip 43 to keep the guide plate 42 at a certain height.

[0032] In practical implementation, the limiting block 314 first drives the support rod 313 to make the initial fixing plate 311 cooperate with the top of the conveyor belt 2, so that the height of the initial fixing plate 311 and the height of the top of the conveyor belt 2 remain stable. By rotating the turntable 316, the threaded rotating rod 315 is driven to control the height of the positioning box 310. The positioning box 310 drives the lifting plate 39 to move synchronously, that is, the lifting plate 39 drives the belt pull strip 36 to maintain the height synchronously. Thus, the belt pull strip 36 drives the two rotating shafts 34 to move synchronously to the required height. The rotating shaft 34 drives the pulley 33 and the same belt strip 32 to maintain the same height. The same belt strip 32 drives multiple scraper strips 31 to maintain the same height. That is, the height of the multiple scraper strips 31 is the height of the coating thickness on the surface of the fabric on the conveyor belt 2. Thus, the motor 35 can start and drive the rotating shaft 34 to rotate. The rotating shaft 34 drives the pulley 33 and the same belt strip 32 to make the multiple scraper strips 31 scrape off the excess coating on the surface of the fabric on the conveyor belt 2 in sequence. This achieves the uniform scraping of the coating on the surface of the fabric on the production line and precise control of the coating thickness on the fabric. At the same time, the support spring 46 supports the pressing clamping plate 44 to move upward and make the bottom limiting roller 45 fit against the bottom of the conveyor belt 2, thereby determining the position of the clamping plate 44. The clamping plate 44 drives the belt support strip 43 to keep the guide plate 42 at a certain height. The guide plate 42 makes up the height difference between the top outer wall of the conveyor belt 2 and the top outer wall of the collection box 41. As a result, the paint scraped by multiple scraper strips 31 on the conveyor belt 2 can slide down and enter the collection box 41, thereby avoiding the overflow and waste of paint during the lamination process due to excessive paint on the fabric.
