Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of self-adhesive paper, in particular to a back-side gluing device for the production of self-adhesive paper. Background Art
[0002] Most of the self-adhesive paper is made of high-strength white board paper as the base paper, which is coated with self-adhesive paper to become self-adhesive paper.
[0003] When the self-adhesive paper is produced, the transmission roller drives the self-adhesive base paper to be evenly transmitted. During the transmission process, the self-adhesive is sprayed on the self-adhesive base paper to complete the gluing process of the self-adhesive base paper.
[0004] In the prior art, when gluing the back side of the self-adhesive base paper, glue is sprayed directly onto the self-adhesive base paper through a nozzle. However, in the prior art, the thickness of the spraying is controlled by the spraying time, and repeated spraying is performed in some areas, resulting in uneven glue thickness on the back side of the self-adhesive base paper. At the same time, in order to spray glue on the edge during spraying, it is necessary to move to the edge during spraying, which causes the glue to be sprayed on the area without the self-adhesive base paper, resulting in a waste of raw materials. Therefore, we propose a back-gluing device for the production of self-adhesive paper. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a back-side gluing device for the production of self-adhesive paper, which solves the problem of uneven glue coating thickness on the back of the self-adhesive base paper and the need to move to the edge during spraying in order to spray glue on the edge, which causes glue to be sprayed on areas without self-adhesive base paper, resulting in a waste of raw materials.

[0009] Preferably, a spring is sleeved on the outer peripheral wall of the threaded rod, a nut is threadedly connected to the outer peripheral wall of the threaded rod, and the nut is fitted with a fixing seat.

[0015] The utility model discloses a back-side gluing device for producing self-adhesive paper, which has the following beneficial effects:

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The embodiment of the present application provides a back-side gluing device for the production of self-adhesive paper, thereby solving the problem of uneven glue coating thickness on the back side of the self-adhesive base paper. At the same time, in order to spray glue on the edge during spraying, it is necessary to move to the edge during spraying, which causes the glue to be sprayed on the area without the self-adhesive base paper, resulting in waste of raw materials. The problem is achieved by limiting the height of the connecting seat 404, limiting the distance between the scraper 5 and the sprayer 1, and then limiting the glue thickness through the scraper 5, and flattening the glue through the scraper 5. By adjusting the distance between the two side plates 501, the width of the sprayed glue is limited, thereby preventing the glue from being sprayed outside the self-adhesive paper and causing waste of raw materials.
[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] The utility model embodiment discloses a back-side gluing device for producing self-adhesive paper.
[0027] According to the attached Figure 1-4 As shown, the sprayer 1 includes a transmission shaft 2 which is connected to the sprayer 1, a nozzle 3 is installed on the transmission shaft 2, the nozzle 3 is connected to the glue barrel through a feeding pipe, and the glue is sprayed on the adhesive raw material paper through the nozzle 3. The transmission shaft 2 is provided with:
[0028] A height unit, the height unit includes a threaded rod 4, a fixed seat 401 and a connecting seat 404, the fixed seat 401 is fixedly connected to the transmission shaft 2, the threaded rod 4 is slidably connected to the inner wall of the fixed seat 401, and the bottom end surface of the fixed seat 401 is fixedly connected to the connecting seat 404. The height unit is used to adjust the height of the connecting seat 404, and the threaded rod 4 slides along the fixed seat 401 to drive the connecting seat 404 to move. At this time, the height of the connecting seat 404 and the upper surface of the sprayer 1 is adjusted to a suitable height to limit the thickness of the sprayed glue;
[0029] The scraping unit includes a scraper 5 and a side plate 501. The scraper 5 is fixedly connected to the connecting seat 404. The side plate 501 is slidably connected to the inner wall of the threaded rod 4. The scraping unit is used to adjust the position of the side plate 501 on the threaded rod 4. By limiting the height of the connecting seat 404, the distance between the scraper 5 and the sprayer 1 is limited, and then the glue thickness is limited by the scraper 5. The glue is scraped flat by the scraper 5. By adjusting the distance between the two side plates 501, the width of the sprayed glue is limited to prevent the glue from being sprayed outside the self-adhesive paper, resulting in waste of raw materials.
[0030] A spring 402 is sleeved on the outer wall of the threaded rod 4, and a nut 403 is threadedly connected to the outer wall of the threaded rod 4. The nut 403 fits with the fixing seat 401. By rotating the nut 403, the nut 403 rotates along the outer wall of the threaded rod 4, so that the nut 403 moves along the threaded rod 4.
[0031] The two ends of the spring 402 are fixedly connected to the fixing seat 401 and the connecting seat 404 respectively. Under the rebound of the spring 402 , the nut 403 is pushed to contact the fixing seat 401 to limit the height of the connecting seat 404 .
[0032] The top end surface of the connecting seat 404 is fixedly connected with a rotating seat 602 , and a bidirectional screw rod 6 is rotatably connected between the rotating seats 602 .
[0033] A center seat 601 is rotatably connected to the outer peripheral wall of the bidirectional screw rod 6, and the center seat 601 is fixedly connected to the top end surface of the connecting seat 404. Under the action of the center seat 601 and the rotating seat 602, the rotation of the bidirectional screw rod 6 on the connecting seat 404 is stable.
[0034] The outer peripheral wall of the bidirectional screw rod 6 is fixedly connected with a rotating wheel.
[0035] The bidirectional screw rod 6 is threadedly connected to the side plate 501. The rotation of the rotating wheel drives the bidirectional screw rod 6 to rotate. The rotation of the bidirectional screw rod 6 causes the side plate 501 threadedly connected thereto to rotate. At this time, the side plate 501 moves in opposite directions along the inner wall of the connecting seat 404, thereby changing the distance between the two side plates 501.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
