Description

Technical Field

[0001] This utility model relates to the field of unblocking devices, and more specifically, to an unblocking device for a glue applicator hose. Background Technology

[0002] The glue applicator hose is a key component of the glue applicator equipment. Its main function is to transport liquid glue from the glue reservoir to the applicator head and evenly apply it to the workpiece surface through nozzles or scrapers. The hose typically consists of a corrosion-resistant inner layer, a high-strength reinforcing layer, and a wear-resistant outer layer to ensure its stability and durability in different working environments. Glue applicator hoses are widely used in packaging, printing, woodworking, automotive, electronics and other industries to meet the bonding, sealing or coating needs of different materials. With prolonged use, the glue applicator hose will gradually accumulate old glue residue, eventually clogging the hose. At this point, it is necessary to use a unclogging device to clear the blockage.

[0003] For example, Chinese patent disclosure: A product adhesive application mechanism, application number: CN202221331555.0, includes an adhesive tube and an adhesive application needle structure disposed at the end of the adhesive tube and communicating with its inner cavity; it also includes a unclogging needle structure and a driving structure; the driving structure is used to drive the unclogging needle structure to move axially within the adhesive tube, so that the needle-shaped unclogging part of the unclogging needle structure extends into the needle head of the adhesive application needle structure to prevent blockage and unclog it. This utility model can timely and effectively prevent blockage and unclog the needle head of the adhesive application needle structure, and is simple to operate, saves time, effort and cost, and has a good unclogging effect.

[0004] However, in the above-mentioned technical solutions, during the long-term operation of the glue applicator, the inside of the glue tube is prone to stubborn blockage due to glue solidification, solvent evaporation, or foreign matter mixing. The currently widely used needle-type unblocking technology has obvious limitations. Traditional needles can only perform simple mechanical piercing of the inner cavity of the glue tube, and it is difficult to completely remove the solidified glue layer adhering to the tube wall. Operators often need to pierce and insert the needle repeatedly to achieve a basic unblocking effect, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] The main purpose of this utility model is to provide a device for unclogging glue hoses of glue applicators, which can effectively solve the problem in the background art where glue hoses are easily clogged due to glue solidification, solvent evaporation, or foreign matter mixing during long-term operation of glue applicators. The currently widely used needle-type unclogging technology has obvious limitations. Traditional needles can only perform simple mechanical piercing of the inner cavity of the glue hose, and it is difficult to completely remove the solidified glue layer adhering to the hose wall. Operators often need to pierce and insert the needles repeatedly to achieve a basic unclogging effect, which is time-consuming, labor-intensive, and inefficient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a glue applicator hose unblocking device, comprising a base, a guide groove provided on the base, a moving component provided in the guide groove, a plurality of first grooves provided on one side of the base, a plurality of second grooves provided on the side above the first grooves, the first grooves and second grooves being staggered, a scraper being slidably provided in both the first grooves and the second grooves, a push post and a plurality of springs being fixedly provided on the side of the scraper near the guide groove, one side of the push post being located in the guide groove, a groove being provided on the side of both the first grooves and the second grooves near the guide groove, and a ball bearing being provided on one side of the push post.

[0007] Preferably, the scraper is arc-shaped, the pusher is slidably connected to the base, and the spring is fixedly installed in the groove.

[0008] Preferably, the moving component has a polygonal column slidably disposed within the guide groove, and one side of the polygonal column has several inclined surfaces.

[0009] Preferably, the polygonal column is provided with a threaded hole, a threaded post is provided in the threaded hole, a rotating post is fixedly provided on one side of the threaded post, and a knob is provided on the rotating post.

[0010] Preferably, one side of the rotating column extends through to the outside of the base.

[0011] Preferably, the knob is fixedly mounted on the side of the rotating column located outside the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When using this utility model, insert the base into the rubber tube, and then turn the knob. The knob drives the threaded column to rotate through the rotating column. Then, through the threaded column and the threaded hole, the polygonal column moves away from the knob. Then, the inclined inner wall of the polygonal column squeezes the ball, causing the push column to move closer to the scraper. The push column drives the scraper to move, and the spring deforms, causing part of the scraper to move to the outside of the base. After the scraper has moved, the arc-shaped outer wall surface of the scraper is attached to the inner wall surface of the rubber tube. Then, pull the base to remove the base from the rubber tube. At this time, the base drives the unfolded scraper to move. Use the scraper to scrape out the old glue adhering to the rubber tube in one go, thus completing the unblocking of the rubber tube. The unblocking efficiency is high, and there is no need to repeatedly unblock the rubber tube. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 4 As shown, a glue applicator hose unblocking device includes a base 1, a guide groove 2 on the base 1, a moving component 3 inside the guide groove 2, a plurality of first grooves 4 on one side of the base 1, a plurality of second grooves 5 above the first grooves 4, the first grooves 4 and the second grooves 5 are staggered, a scraper 6 is slidably disposed in both the first grooves 4 and the second grooves 5, a push post 7 and a plurality of springs 8 are fixedly disposed on the side of the scraper 6 near the guide groove 2, one side of the push post 7 is located in the guide groove 2, a groove 9 is provided on the side of both the first grooves 4 and the second grooves 5 near the guide groove 2, and a ball bearing 10 is disposed on one side of the push post 7.

[0022] like Figure 5 As shown, in another embodiment of the present invention, the moving component 3 is slidably provided with a polygonal column 301 in the guide groove 2, and a plurality of inclined surfaces 302 are provided on one side of the polygonal column 301.

[0023] The polygonal post 301 is provided with a threaded hole 303, and a threaded post 304 is provided in the threaded hole 303. A rotating post 305 is fixedly provided on one side of the threaded post 304, and a knob 306 is provided on the rotating post 305.

[0024] When it is necessary to move the scraper 6, turn the knob 306. The knob 306 drives the threaded column 304 to rotate through the rotating column 305. Then, through the threaded column 304 and the threaded hole 303, the polygonal column 301 moves away from the knob 306. Then, the inner wall of the inclined surface 302 on the polygonal column 301 squeezes the ball 10, causing the push column 7 to move closer to the scraper 6. The push column 7 drives the scraper 6 to move.

[0025] The working principle of this glue applicator hose unblocking device:

[0026] In use, insert the base 1 into the hose, then turn the knob 306. The knob 306 drives the threaded column 304 to rotate via the rotating column 305. The threaded column 304 and the threaded hole 303 then move the polygonal column 301 away from the knob 306. The inner wall of the inclined surface 302 on the polygonal column 301 then presses the ball bearing 10, causing the push column 7 to move closer to the scraper 6. The push column 7 drives the scraper 6 to move, and the spring 8 deforms, causing part of the scraper 6 to move outside the base 1. After the scraper 6 has moved, the arc-shaped outer wall surface of the scraper 6 is in contact with the inner wall surface of the hose. Then, pull the base 1 to remove it from the hose. At this time, the base 1 drives the unfolded scraper 6 to move. The scraper 6 scrapes out the old glue adhering to the hose in one go, completing the unblocking of the hose. The unblocking efficiency is high, and there is no need to repeatedly unblock the hose.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
