Description

Technical Field

[0001] This utility model belongs to the field of tape production technology, and more specifically, it relates to a tape production coating device. Background Technology

[0002] In the tape production process, the coating process is the core link that determines the product quality, and its quality directly affects the tape's adhesive uniformity, thickness consistency, and performance.

[0003] Current tape coating equipment still has the following shortcomings: Traditional coating equipment lacks precision in controlling the material feeding. It often uses a single valve or gravity feeding method, which can easily lead to uneven coating thickness due to changes in material viscosity and unstable feeding pressure. This can result in localized areas that are too thick or too thin, affecting product quality stability. Furthermore, the material feeding speed adjustment method of existing equipment is complex and cannot quickly adapt to the production needs of tapes of different specifications and thicknesses. A lot of time is required to adjust parameters when changing products. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a tape production coating device to solve the problems mentioned in the background art, such as insufficient precision in controlling the material feeding of traditional coating devices, which affects the stability of product quality, and the complex material feeding speed adjustment method of existing devices, which makes it difficult to quickly adapt to the production needs of tapes of different specifications and thicknesses.

[0005] The purpose and effect of this utility model's tape production coating device are achieved by the following specific technical means: A tape coating device includes: a base; the base adopts a rectangular plate structure, and a through rectangular groove structure is opened on the top of the base; a set of rectangular plate side plates are fixedly arranged on both sides of the top of the base; a mixing chamber is fixedly arranged on the top between the two sets of side plates; a wedge-shaped groove feeding trough is fixedly arranged on the top between the two sets of side plates, and a discharge port is opened at the bottom of the feeding trough; three sets of circular tube feeding pipes are arranged in a row at the bottom of the mixing chamber, and springs are sleeved on the outer side of the feeding pipes; a rectangular plate pressure plate is slidably arranged on the outer side of the three sets of feeding pipes, and the outer wall of the pressure plate is in contact with the inner wall of the feeding trough.

[0006] Furthermore, a set of cylindrical guide rollers is rotatably connected to both the front and rear sides between the two sets of side plates; a cylindrical glue-applying roller is rotatably arranged in the middle between the two sets of side plates, and the glue-applying roller is located below the material feeding trough; a glue pump is provided at the top of the mixing chamber; a rectangular groove collection trough is fixedly arranged in the rectangular through groove of the base, and the collection trough is connected to the glue pump through a pipe.

[0007] Furthermore, a set of cylindrical fixing rods are fixedly installed on both sides of the top of the pressure plate; and a ring-shaped counterweight is arranged on the outer side of the fixing rods.

[0008] Furthermore, a scraper with a wedge-shaped plate structure is fixedly provided on the rear side between the two sets of side plates, and the front side of the scraper is in contact with the rear outer wall of the coating roller; a motor is fixedly provided on one side of the side plate.

[0009] Furthermore, a slide rail is fixedly connected between the two sets of side plates; a lead screw is rotatably provided on the inner side of the slide rail, and the lead screw is connected to the motor drive; a cleaning plate with a rectangular plate structure is slidably provided on the front side of the slide rail, and the cleaning plate is connected to the lead screw through a threaded engagement, with the top surface of the cleaning plate in contact with the bottom surface of the scraper.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The pressure plate structure, which combines counterweights and springs, applies uniform and stable pressure to the adhesive in the feeding trough, ensuring that the adhesive flows out of the outlet at a constant speed and that the adhesive is evenly distributed on the surface of the coating roller. At the same time, the scraper removes excess adhesive from the surface of the coating roller, further ensuring the uniformity of the coating thickness on the substrate surface and significantly improving product quality.

[0011] An assembly trough is set up to collect excess and scattered adhesive material scraped off by the scraper. The recycled adhesive material is then pumped back to the mixing chamber for reuse via an adhesive pump, forming a closed-loop circulation system that significantly reduces adhesive waste and lowers production costs. A motor-driven screw drives a cleaning plate to reciprocate along a slide rail, automatically cleaning residual adhesive material from the scraper. This prevents adhesive buildup from affecting the scraping effect, reduces manual cleaning workload, and improves production continuity and efficiency.

[0012] The pressure of the pressure plate on the adhesive material can be quickly adjusted by increasing or decreasing the number of counterweights, thereby controlling the feeding speed. The operation is simple and convenient, and it can quickly adapt to the production needs of different specifications of adhesive tape, shortening the changeover and debugging time.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a tape production coating device, including: a base 1; the base 1 adopts a rectangular plate structure, and the top of the base 1 has a through rectangular groove structure; a set of rectangular plate side plates 101 are fixedly arranged on both sides of the top of the base 1; a mixing chamber 104 is fixedly arranged on the top between the two sets of side plates 101; a wedge-shaped groove feeding trough 106 is fixedly arranged on the top between the two sets of side plates 101, and the bottom of the feeding trough 106 has a discharge port; three sets of cylindrical feeding pipes 107 are arranged in a circular tube structure at the bottom of the mixing chamber 104, and springs are sleeved on the outside of the feeding pipes 107, which can keep the pressure plate 108 under downward pressure at all times; a rectangular plate pressure plate 108 is slidably arranged on the outside of the three sets of feeding pipes 107, and the outer wall of the pressure plate 108 is in contact with the inner wall of the feeding trough 106, and the feeding speed is controlled by the pressure applied by the pressure plate 108.

[0021] Among them, a set of cylindrical guide rollers 102 are rotatably connected to both the front and rear sides between the two sets of side plates 101 to guide the substrate to be transported smoothly; a cylindrical glue-applying roller 103 is rotatably arranged in the middle between the two sets of side plates 101, and the glue-applying roller 103 is located below the material discharge trough 106; a glue pump 105 is arranged at the top of the mixing chamber 104; a rectangular groove structure collection trough 116 is fixedly arranged in the rectangular through groove of the base 1, and the collection trough 116 is connected to the glue pump 105 through a pipe to form a glue recycling system.

[0022] The pressure plate 108 has a set of cylindrical fixing rods 109 fixed on both sides of its top. The outer side of the fixing rods 109 is provided with ring-shaped counterweights 110. The pressure of the pressure plate 108 on the rubber material can be adjusted by increasing or decreasing the number of counterweights 110, thereby controlling the feeding speed.

[0023] The adhesive is first injected into the mixing chamber 104 for mixing. Then, under the action of the adhesive pump 105, it flows at a constant speed into the feeding trough 106 through the feeding pipe 107. The pressure of the pressure plate 108 is adjusted according to the required adhesive feeding speed. By adding or removing the number of counterweights 110 outside the fixed rod 109, the pressure of the pressure plate 108 on the adhesive in the feeding trough 106 is changed, thereby controlling the adhesive feeding speed. During the addition of counterweights 110, it is ensured that they are neatly arranged and firmly connected to the fixed rod 109. Through the cooperation of the counterweights 110 and the springs outside the feeding pipe 107, the pressure plate 108 exerts pressure on the adhesive in the feeding trough 106. Applying pressure to the material ensures uniform pressure across all parts of the feeding trough 106, allowing the adhesive to flow smoothly and evenly onto the coating roller 103 below. This also improves the uniformity of the adhesive flow onto the coating roller 103, enhancing the practicality of the device. Placing the substrate to be coated with adhesive at the feed end of the device allows it to pass smoothly through the surface of the coating roller 103 under the guidance of the guide roller 102, ensuring good contact between the substrate and the coating roller 103 surface and a smooth conveying path. As the coating roller 103 rotates, the adhesive on its surface is evenly coated onto the surface of the substrate.

[0024] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown: Among them, a scraper 111 with a wedge-shaped plate structure is fixedly installed on the rear side between the two sets of side plates 101, and the front side of the scraper 111 is in contact with the rear outer wall of the coating roller 103 to scrape off excess adhesive on the surface of the coating roller 103; a motor 112 is fixedly installed on one side of the side plate 101 as the power source of the cleaning mechanism.

[0025] A slide rail 113 is fixedly connected between the two sets of side plates 101. A lead screw 114 is rotatably mounted on the inner side of the slide rail 113 and is connected to the motor 112. A rectangular cleaning plate 115 is slidably mounted on the front side of the slide rail 113 and is connected to the lead screw 114 by a threaded engagement. The top surface of the cleaning plate 115 is in contact with the bottom surface of the scraper 111. When the motor 112 drives the lead screw 114 to rotate, the cleaning plate 115 can reciprocate along the slide rail 113 to clean the residual adhesive on the scraper 111.

[0026] The specific usage and function of this embodiment are as follows: In this invention, during the glue application process, the scraper 111 remains in contact with the rear outer wall of the glue application roller 103. As the glue application roller 103 rotates, any remaining glue after application is scraped off, preventing the glue from solidifying or accumulating on the outside of the roller. This avoids the glue solidifying and affecting the application quality, and also prevents uneven glue levels in different areas, thus improving the overall application quality. During the scraping process, the motor 112 is started, driving the lead screw 114 to rotate. As the lead screw 114 rotates, the cleaning plate 115 reciprocates along the slide rail 113. During this movement, the top surface of the cleaning plate 115 contacts the bottom surface of the scraper 111, cleaning the remaining glue off the scraper 111 and maintaining its cleanliness. The glue on the scraper 111 falls into the collection trough 116 below for reuse, completing the entire recycling process.
