Description

Technical Field

[0001] This utility model relates to the field of tape production technology, and in particular to an adhesive coating device. Background Technology

[0002] Adhesive tapes can be categorized by their function into high-temperature tapes, double-sided tapes, insulating tapes, specialty tapes, pressure-sensitive tapes, die-cut tapes, etc., each suited to different industry needs. A layer of adhesive is coated on the surface of the tape to bond objects. The earliest adhesives came from animals and plants; in the 19th century, rubber was the main component of adhesives, while modern adhesives widely use various polymers. The tape production process utilizes coating equipment, which applies specific adhesives, coatings, or inks to the tape substrate. The substrate typically includes materials such as plastic film, paper, cloth, and leather. After coating, the tape is dried, then wound and packaged, completing the tape coating process.

[0003] Existing adhesive coating devices use a scraper to spread the adhesive evenly. However, when there is no adhesive or a small amount of adhesive in a certain area of ​​the substrate, the excess adhesive cannot be filled in. Therefore, the adhesive cannot be evenly distributed on the surface of the substrate, resulting in uneven coating and affecting the quality of the tape. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 and Figure 5 This is the first embodiment of the present utility model, which provides an adhesive coating device, mainly including: a coating main component 100, an adhesive supply component 200 and a scraping component 300;

[0032] The coating main component 100 includes a box 101 and a coating roller 102 and a guide roller 103 that are rotatably connected to the inside of the box 101 via bearings. The coating roller 102 is used to coat the surface of the tape substrate with adhesive, and the guide roller 103 is used to guide the substrate.

[0033] The glue supply assembly 200 is connected to the housing 101 and is used to add glue to the glue application roller 102;

[0034] The leveling assembly 300 includes a hydraulic cylinder 301 bolted to the top of the housing 101. The piston end of the hydraulic cylinder 301 is inserted into the housing 101 and bolted to a mounting plate 302. A leveling mechanism 303 and a scraper 304 for leveling the adhesive are fixedly mounted on the bottom of the mounting plate 302. The hydraulic cylinder 301 is used to adjust the distance between the leveling mechanism 303, the scraper 304, and the substrate, allowing for adjustment of the adhesive thickness according to production needs. The leveling mechanism 303 fills areas with little or no adhesive with excess glue, preventing insufficient glue coverage in certain areas of the substrate and improving the quality of tape production.

[0035] Example 2

[0036] Reference Figure 2This is the second embodiment of the present invention. Unlike the previous embodiment, support legs 104 are bolted to the four corners of the bottom of the box 101 to support the box 101. The box 101 has an inlet 105 and an outlet 106 on its left and right sides, respectively. A pair of guide rollers 103 are symmetrically arranged on the left and right sides of the coating roller 102, corresponding to the inlet 105 and outlet 106, and the guide rollers 103 are positioned higher than the coating roller 102. In use, the substrate enters the box 101 through the inlet 105, passes through the upper side of the guide roller 103 and the lower side of the coating roller 102, and finally exits the box 101 through the outlet 106. During this process, the substrate is coated with adhesive by the coating roller 102.

[0037] Furthermore, the inner walls of the left and right sides of the housing 101 are symmetrically provided with inclined surfaces, and the lower end of the inclined surfaces is located on the inner bottom wall of the housing 101. A glue discharge pipe 107 is fixedly connected to the center of the bottom of the housing 101, and a valve is installed on the glue discharge pipe 107. By providing inclined surfaces, excess glue scraped off can be collected at the glue discharge pipe 107, making it convenient to collect excess glue and to discharge excess glue from the housing 101.

[0038] Example 3

[0039] Reference Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the glue supply component 200 is located directly above the glue application roller 102. The glue supply component 200 includes a glue storage tank 201 with a lid that is fixedly connected to the top of the box 101. A glue outlet pipe 202 is fixedly connected to the bottom of the glue storage tank 201. The bottom end of the glue outlet pipe 202 extends into the inside of the box 101 and is fixedly connected to a diversion pipe 203. A plurality of evenly distributed glue addition pipes 204 are fixedly connected to the bottom of the diversion pipe 203. Each of the glue addition pipes 204 is equipped with a solenoid valve, which is controlled to open and close by a controller.

[0040] When applying adhesive, the solenoid valve is opened by the controller. After opening, the adhesive in the adhesive addition tube 204 falls onto the substrate. The adhesive in the adhesive addition tube 204 is then replenished through the diversion tube 203, the dispensing tube 202, the adhesive storage tank 201, etc. After the adhesive application is completed, the solenoid valve is closed by the controller.

[0041] Example 4

[0042] Reference Figure 3 and Figure 5This is the second embodiment of the present invention. Unlike the previous embodiment, the scraping component 300 is located above the guide roller 103 inside the housing 101 and is positioned near the discharge port 106. The flattening mechanism 303 includes a rotary motor 303-1 that is fixedly connected to the bottom of the mounting plate 302 by bolts, and a rotating rod 303-2 that is fixedly connected to the bottom output shaft of the rotary motor 303-1. The bottom end of the rotating rod 303-2 has a pointed structure. In use, the rotary motor 303-1 can drive the rotating rod 303-2 to rotate. During the rotation process, the rotating rod 303-2 can scrape off excess glue from the surface of the substrate and fill the excess glue into areas with no glue or little glue, thus avoiding situations where there is a lack of glue or a small amount of glue in a certain part of the substrate and improving the production quality of the tape.

[0043] Furthermore, a pair of guide rods 305 are fixedly connected to the top of the mounting plate 302. The tops of the pair of guide rods 305 extend slidably to the top of the housing 101 to guide the lifting and lowering of the mounting plate 302 and improve the stability of the mounting plate 302.

[0044] In summary, during actual use, the substrate enters the housing 101 through the inlet 105, passes through the upper side of the guide roller 103 and the lower side of the coating roller 102, and finally exits the housing 101 through the outlet 106. During the process of the substrate entering and exiting, the adhesive in the storage tank 201 flows through the outlet pipe 202 into the diversion pipe 203, and then flows through the diversion pipe 203 into several adhesive addition pipes 204. From there, the adhesive falls onto different positions of the coating roller 102. As the substrate passes through the coating roller 102, the adhesive on the coating roller 102 is applied to the substrate. When the substrate coated with adhesive moves to the rotating rod 303-2, it is rotated... The rotating motor 303-1 drives the rotating rod 303-2 to rotate. During the rotation, the rotating rod 303-2 can scrape off excess glue from the surface of the substrate. In addition, during the rotation, it can fill the areas with no glue or little glue with the scraped excess glue, so as to avoid the situation that there is a lack of glue or insufficient glue in certain places on the substrate. This can improve the production quality of the tape. After being flattened by the rotating rod 303-2, the glue on the surface of the substrate is scraped flat by the scraper 304, so that the glue thickness is uniform. The glue is flattened and then scraped flat by the scraper 304, so that the glue thickness is uniform, which can further improve the production quality of the tape.

[0045] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
