Description

Technical Field

[0001] The utility model belongs to the technical field of tape gluing, and specifically relates to a coating device for tape gluing. Background Art

[0002] Tapes can be classified according to their functions into: high-temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, and die-cut tapes. Different functions are suitable for different industry needs. A layer of adhesive is applied to the surface of the tape to make the tape stick to objects. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; while various polymers are widely used nowadays.

[0003] When the existing tapes are coated, the glue on the side of the tape cannot be effectively treated, resulting in many tapes having very sticky sides when purchased, and they will also get dirty by sticking to dust after use. Summary of the Utility Model

[0005] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] A coating device for tape gluing of the utility model includes a frame and a coating roller, a tensioning assembly, and a scraping assembly installed on the frame. The scraping assembly includes a V-shaped part and a scraping plate. The V-shaped part presses on the back of the tape, and the scraping plate is symmetrically installed on the frame through a mounting rod. The scraping plate contacts the side of the tape. The front of the tape contacts the coating roller for gluing, and the tape is transmitted around the tensioning assembly. A connecting sleeve is provided on the scraping plate, the connecting sleeve is sleeved on the mounting rod, and the connecting sleeve is locked by a locking screw.

[0007] Preferably, the tensioning assembly includes a first tensioning wheel and a second tensioning wheel. The back of the tape is attached to the first tensioning wheel and the second tensioning wheel, and the coating roller is located between the first tensioning wheel and the second tensioning wheel.

[0008] Preferably, the scraping assembly is located between the coating roller and the second tensioning wheel, and the connection line of the lowest points of the first tensioning wheel and the second tensioning wheel passes through the coating roller.

[0009] Preferably, the V-shaped part is composed of two symmetric metal plates, the metal plates are inclined, and the angle between the metal plates and the surface of the tape is 60°.

[0010] Preferably, the upper half of the scraping plate is bent and twisted, and a notch is provided at the bent and twisted part, and the edge of the tape is stuck in the notch. Advantageous Effects

[0011] Adopting the technical solution provided by the utility model, compared with the prior art, it has the following advantageous effects:

[0012] A coating device for applying glue to a tape of the present utility model moves on a coating roller as the film rotates, and the coating roller performs glue coating operations on the film. However, there will be a situation where glue adheres to the back and sides of the tape and needs to be processed. At this time, the film coated with glue passes through a glue scraping assembly, first contacts the V-shaped part, and the V-shaped part scrapes the glue on the back of the tape, causing the remaining glue to accumulate and move along the V-shaped part towards both sides and finally separate from the tape. The glue scraping plate contacts the side of the tape to scrape the glue on the side of the tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Refer to the attached Figures 1-3, A coating device for applying glue to a tape in this embodiment includes a frame 100, a glue coating roller 200, a tensioning assembly 300, and a glue scraping assembly 400 mounted on the frame 100. The glue scraping assembly 400 includes a V-shaped part 410 and a glue scraping plate 420. The V-shaped part 410 presses on the back of the tape, and the glue scraping plate 420 is symmetrically mounted on the frame 100 through a mounting rod 440. The glue scraping plate 420 contacts the side of the tape. The front of the tape contacts the glue coating roller 200 for glue coating, and the tape is transmitted around the tensioning assembly 300. A connecting sleeve 430 is provided on the glue scraping plate 420. The connecting sleeve 430 is sleeved on the mounting rod 440 and locked by a locking screw. It should be noted that the focus of this device is the overall description of the tape coating structure. Regarding the specific structure of the glue coating roller 200 and how to apply glue to the tape, it is in the prior art and will not be elaborated here.

[0028] The tensioning assembly 300 in this embodiment includes a first tensioning wheel 310 and a second tensioning wheel 320. The back of the tape is attached to the first tensioning wheel 310 and the second tensioning wheel 320, and the glue coating roller 200 is located between the first tensioning wheel 310 and the second tensioning wheel 320.

[0029] The glue scraping assembly 400 in this embodiment is located between the glue coating roller 200 and the second tensioning wheel 320, and the connection line of the lowest points of the first tensioning wheel 310 and the second tensioning wheel 320 passes through the glue coating roller 200.

[0030] The V-shaped part 410 in this embodiment is composed of two symmetric metal plates. The metal plates are inclined and form an angle of 60° with the surface of the tape.

[0031] The upper half of the glue scraping plate 420 in this embodiment is bent and distorted, and there is a notch at the bent and distorted part. The edge of the tape is stuck in the notch. This designed structure prevents the side glue from moving back towards the center of the back of the tape when scraping the side glue. It should be noted that the degree of distortion is not large. Compared with the lower half, the distortion is within 30°.

[0032] Working principle: When applying glue to the tape, the tape is installed on an external rotating winding and unwinding device, and the tape is made to contact the tensioning assembly 300 so that the area where the tape contacts the glue applicator roller 200 is in a taut state. As the film rotates and moves on the glue applicator roller 200, the glue applicator roller 200 applies glue to the film. However, there may be a situation where glue adheres to the back and sides of the tape and needs to be processed. At this time, the film coated with glue passes through the glue scraping assembly 400 and first contacts the V-shaped part 410. The V-shaped part 410 scrapes the glue on the back of the tape, causing the remaining glue to accumulate and move along the V-shaped part 410 towards both sides and finally separate from the tape. The glue scraping plate 420 contacts the side of the tape to scrape the glue on the side of the tape. It should be noted that the treatment of the back is mainly to prevent fresh glue from remaining on the second tensioning wheel 320 as it passes through the second tensioning wheel 320 on the back of the tape.

[0033] The above-described embodiments merely represent certain implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present utility model; it should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model; therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
