Abstract
Description
Technical Field
[0001] This utility model relates to the field of tape processing technology, specifically to a tape adhesive coating device. Background Technology
[0002] The adhesive tape industry is a sector focused on the production, sales, and application of adhesive tapes. In tape production, the coating step involves preparing acrylic pressure-sensitive adhesive emulsion, anti-counterfeiting materials, degradation aids, and other coating materials according to product requirements. The acrylic pressure-sensitive adhesive emulsion and anti-counterfeiting materials are then evenly coated onto the printed BOPP film using methods such as roller coating or blade coating.
[0003] A search revealed an automatic coating device for tape processing, with publication number CN215843854U. This device includes a housing, a coating mechanism, and a hopper, designed to address the problem that conventional coating methods cannot guarantee a uniform distribution of adhesive on the tape. While this device uses a pressure roller for auxiliary coating, it lacks a recycling mechanism for excess material on the tape surface, which can affect the uniformity of the coating and result in low adhesive utilization. Therefore, we propose a tape adhesive coating device. Utility Model Content

[0022] Please see Figure 1 A tape adhesive coating device includes: a fixing block 801 at the connection between a tape stretching mechanism 8 and a coating table 2, the fixing block 801 being symmetrically positioned about the central axis of the coating table 2, a connecting shaft 802 being symmetrically fixed to one outer wall of the fixing block 801, and a tape threading roller 803 being sleeved on the other end of the connecting shaft 802 via a bearing, the tape threading roller 803 and the connecting shaft 802 being symmetrically positioned about the central axis of the fixing block 801, and the tape threading roller 803 being rotatably connected to the coating table 2 via the connecting shaft 802, the tape threading roller 803 rotating on one side of the fixing block 801 via the connecting shaft 802, and the U-shaped structure facilitating the threading and movement of the tape, reducing abrasion of the tape, and improving coating quality.
[0023] Working Principle: For this type of adhesive tape coating device, the operator first places the coating device on a stable, level working surface in the working environment, and pours the adhesive to be coated into the adhesive pool 3 on the coating table 2. Then, the heating base 5 is activated, allowing the heating base 5 to stably heat the adhesive pool 3 and the residue pool 4 inside the base plate 1, keeping the adhesive in a molten state for easy coating. Next, the tape to be coated is passed through the inside of the threading roller 803. The U-shaped threading roller 803 can rotate smoothly on one side of the fixed block 801 via the connecting shaft 802, facilitating the smooth passage of the tape over the coating table 2. Afterwards, the operator starts the second motor 702. The output shaft of 702 controls the precise rotation of the connecting shaft 706 through the reduction gear set 703 and the adjusting shaft 705 set in the reduction box 701. The adjusting shaft 705 drives the scraper 707 to rotate, which makes it easy for the operator to control the distance between the tip of the scraper 707 and the lower surface of the tape. Finally, the operator starts the first motor 602 on the equipment platform 601. The output shaft of the first motor 602 drives the coating roller 604 inside the adhesive pool 3 to rotate through the transmission belt 603. After the coating roller 604 absorbs the adhesive, it coats the tape. The excess material on the coated tape is scraped off by the scraper 707 to control the thickness. The excess material falls into the waste material pool 4 for recycling, which facilitates the reuse of the adhesive and improves the utilization rate of the tape coating material.
