Description

Technical Field

[0001] This utility model relates to the field of advertising paper processing technology, and in particular to a device for rapid gluing of advertising paper surface. Background Technology

[0002] Before advertising paper is pasted, adhesive needs to be applied to its back. For large-sized advertising paper, adhesive is mainly applied using an adhesive roller coating machine, while for small-sized advertising paper, adhesive is usually applied manually.

[0003] However, when applying adhesive to small-sized advertising paper, the adhesive is not evenly distributed on the surface of the paper after being squeezed out, which can easily lead to excessive or thick adhesive in some areas, resulting in waste of adhesive.

[0004] To address this issue, we propose a rapid gluing device for advertising paper surfaces. Utility Model Content

[0005] The purpose of this invention is to provide a device for quickly applying adhesive to the surface of advertising paper, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for rapidly applying adhesive to the surface of advertising paper includes a glue cylinder, a piston block slidably installed inside the glue cylinder, and a glue tube connected below the piston block. An extrusion head is threadedly connected to the outer side of one end of the glue tube extending out of the glue cylinder. The top space inside the glue cylinder is connected to the inside of the extrusion head through the piston block and the glue tube. The bottom surface of the extrusion head has several extrusion holes and several bristles. A slide bar is slidably connected to the outside of the glue cylinder through a convex strip, and a scraper is installed at the lower end of the slide bar.

[0008] In a further embodiment, the inner walls of the rubber sleeve, piston block, rubber tube, and extruder are all coated with an anti-sticking layer.

[0009] In a further embodiment, the piston block has a conical groove at its top, and the inner top of the rubber sleeve has a protruding cone that matches the conical groove.

[0010] In a further embodiment, a baffle is rotatably mounted at the bottom end of the hose, and a torsion spring is sleeved on the rotating shaft of the baffle.

[0011] In a further embodiment, a guide groove is provided on the bottom surface of the slider, and a guide bar is provided on the upper edge of the scraper to slide and connect with the guide groove.

[0012] In a further embodiment, a replenishment port is provided on the outer wall of the rubber tube. A sealing cap is screwed onto the external thread of the replenishment port, and a rubber plug for blocking the replenishment port is provided in the inner center of the sealing cap.

[0013] In a further embodiment, a cap is threaded onto the lower end of the rubber tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features an extrusion head that drives the tube and piston block to squeeze the adhesive into the cartridge. The adhesive then flows along the piston block and tube to the extrusion head, allowing the user to operate the extrusion head while simultaneously applying the adhesive to the surface of the advertising paper using brush bristles. This facilitates rapid dispersion of the adhesive, improving application efficiency. Additionally, a scraper can scrape the adhesive surface after the brush has passed, maintaining uniform adhesive thickness and reducing localized excess adhesive, thus saving on adhesive usage.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 A device for rapidly applying adhesive to the surface of advertising paper includes a glue cylinder 1. A piston block 2 is slidably installed inside the glue cylinder 1. The outer side wall of the piston block 2 is in contact with the inner side wall of the glue cylinder 1, allowing the piston block 2 to move axially within the glue cylinder 1. A glue tube 3 is connected to the bottom of the piston block 2. An opening in the middle of the piston block 2 communicates with the glue tube 3. An extrusion head 4 is threadedly connected to the outer side of one end of the glue tube 3 extending out of the glue cylinder 1. The threaded connection of the extrusion head 4 makes it easy to disassemble relative to the glue tube 3 for cleaning or maintenance. The extrusion head 4 is hollow inside, and several extrusion holes 41 are opened on the bottom surface of the extrusion head 4. The top space inside the glue cylinder 1 is connected to the extrusion head 4 through the piston block 2 and the glue tube 3, so that when the piston block 2 moves upward, it squeezes the glue liquid in the top space inside the glue cylinder 1, causing the glue liquid to flow through the piston block 2 and the glue tube 3 to the extrusion head 4, and finally be extruded from the extrusion holes 41. Several bristles 5 are also installed on the bottom surface of the extrusion head 4, and the extruded glue liquid is distributed among the bristles 5, making it easy to operate the bristles 5 to apply adhesive to the surface of the advertising paper.

[0025] For further details, please refer to Figure 3-4 The inner walls of the glue cylinder 1, piston block 2, glue tube 3 and extruder 4 are all coated with an anti-stick layer 10. The anti-stick layer 10 reduces the residue of glue in the device during the flow process.

[0026] Please see Figure 3 The piston block 2 has a conical groove 21 at its top. The conical groove 21 facilitates the flow of adhesive liquid. The inner top of the glue tube 1 has a protruding cone 12 that matches the conical groove 21. When the piston block 2 moves to the inner top of the glue tube 1, the cone 12 can be pressed into the conical groove 21 to squeeze out the remaining adhesive liquid in the conical groove 21 and let it flow into the glue tube 3.

[0027] Please see Figure 1-4 Considering that the glue in the glue tube 1 needs to be replenished in time when it runs out, a replenishment port is provided on the outer wall of the glue tube 1 for convenient replenishment. The replenishment port is connected to the inside of the glue tube 1. A sealing cap 8 is screwed onto the external thread of the replenishment port, and a rubber plug 81 for blocking the replenishment port is provided in the middle of the inner part of the sealing cap 8. When the sealing cap 8 is tightened, the rubber plug 81 is inserted into the replenishment port to improve the sealing. Since the replenishment port is located at the bottom, the piston block 2 needs to be moved to the bottom of the glue tube 1. At this time, the replenishment port is located above the upper surface of the piston block 2 so that the glue can be replenished.

[0028] Please see Figure 1-3 To facilitate internal maintenance and cleaning of the entire device, a cap 9 is threaded onto the lower end of the rubber tube 1. The cap 9 has an opening in the middle to allow the rubber tube 3 to move through.

[0029] Please see Figure 3 To reduce the automatic overflow of adhesive, a baffle 31 is rotatably installed at the bottom end of the tube 3. One edge of the baffle 31 is rotatably connected to the tube 3 via a rotating shaft. A torsion spring 32 is sleeved on the rotating shaft of the baffle 31. Under the action of the torsion spring 32, the baffle 31 is tightly pressed against the bottom end of the tube 3 to seal it. When the piston block 2 is squeezed upward, the adhesive is squeezed towards the bottom end of the tube 3, thereby opening the baffle 31 and flowing into the extruder head 4.

[0030] Please see Figure 3 To ensure the uniformity of the adhesive thickness after application, a slide bar 6 is slidably connected to the outside of the glue tube 1 via a protrusion 11, and a scraper 7 is installed at the lower end of the slide bar 6. The scraper 7 can scrape over the area after the brush bristles 5 have been applied, thereby ensuring the uniformity of the adhesive spread. Considering that as the amount of adhesive remaining in the glue tube 1 gradually decreases, the length of the glue tube 3 extending out of the glue tube 1 also gradually shortens, the top of the slide bar 6 is designed to slide along the protrusion 11. The protrusion 11 is fixed to the outer wall of the glue tube 1 and parallel to the axis of the glue tube 1, thereby adjusting the length of the scraper 7 extending downwards to match the extended extrusion head 4 and brush bristles 5.

[0031] Specifically, considering that the scraper 7 will wear out after scraping for a long time and needs to be replaced, in order to facilitate its replacement, a guide groove 61 is provided on the bottom surface of the slide bar 6, and a guide bar 71 is provided on the upper edge of the scraper 7 to slide and connect with the guide groove 61. The connection between the scraper 7 and the slide bar 6 can be completed by guiding the guide bar 71 into the guide groove 61.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
