Description

Technical Field

[0001] The utility model relates to the field of glue dispensing valve components, in particular to an automatic glue wiping component used for a glue dispensing valve. Background Art

[0002] With the rapid development of industrial automation technology, dispensing valves are increasingly used in production lines. However, dispensing valves are often blocked due to glue residue during use, affecting production efficiency and product quality. The traditional manual glue wiping method is not only inefficient, but also difficult to ensure the cleaning effect.

[0003] Therefore, the development of an efficient and automated glue wiping component for glue dispensing valves has become an urgent need in the industry. This technology aims to provide an automatic glue wiping component for glue dispensing valves. Through an integrated design, it can achieve efficient and automated cleaning of glue dispensing valves, effectively remove glue residues, improve production efficiency and product quality, and meet the needs of modern industrial production.

[0004] After massive searches, it was found that the prior art publication number is CN219647905U, which discloses a dispensing valve glue cleaning mechanism. The dispensing valve glue cleaning mechanism includes a needle valve glue cleaning unit 100, an injection valve glue cleaning unit 200 and a striker valve glue cleaning unit 300, which can automatically clean the needle valve, the injection valve and the striker valve respectively, solving the problem that after a period of processing, the existing dispensing valve will have glue residue on the dispensing needle. When the residual glue accumulates too much, it will affect the dispensing accuracy and thus affect the product quality.

[0005] Therefore, based on the above search and in combination with the prior art, the above equipment still has the following problem: during the cleaning process of the dispensing valve, the solidified glue deep inside the glue outlet at the bottom of the dispensing valve cannot be removed, which may easily lead to excessive solidification of the glue deep inside and cause blockage, and the cleaning effect cannot clean up to the deep position and process it. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic glue-wiping assembly for a glue dispensing valve to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An automatic glue erasing assembly for a glue dispensing valve comprises a shell, a needle storage box is fixedly mounted on the bottom surface of the shell, a rotatable rotating plate is provided on the bottom surface of the needle storage box, a nailing tube is fixedly connected to the surface of one side of the rotating plate, a rotatable rotating cover is connected to the other side of the rotating plate via a rotating shaft, and a cleaning mechanism is provided inside the shell.

[0009] Further, the cleaning mechanism includes: a cloth winding roller and a cloth collecting roller. A bidirectional motor is arranged below the cloth winding roller. A coupling is arranged on the bottom output shaft of the bidirectional motor. A cleaning cloth is connected between the cloth winding roller and the cloth collecting roller.

[0010] Further, the cleaning mechanism further includes a fixing plate. The side surface of the fixing plate is fixedly installed on the inner side wall of the housing. A rotatable connecting sleeve is arranged at the center of the fixing plate. The cleaning cloth is sleeved on the outer surface of the connecting sleeve.

[0011] Further, a glue removing mechanism is fixedly installed on the inner bottom surface of the housing. The glue removing mechanism includes: a needle table. A rotatable cleaning needle is arranged at the center of the needle table. A plurality of barbs are arranged on the surface of the cleaning needle. A slidable movable plate is arranged on the bottom surface of the needle table.

[0012] Further, a coupling cooperating with the bidirectional motor is arranged on the bottom surface of the movable plate. A transmission belt is connected between the two couplings. An electric push rod capable of driving is connected to one side of the movable plate. The electric push rod is fixedly installed on the inner bottom surface of the housing.

[0013] Further, a dispensing valve body is arranged above the housing. A dispensing port is fixedly installed at the bottom of the dispensing valve body. An insertion hole cooperating with the dispensing port is opened on the upper surface of the housing.

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

[0015] 1. In this solution, by providing a cleaning mechanism, efficient automatic cleaning of the dispensing valve is achieved. During the glue wiping process, the drive motor drives the cleaning cloth to gradually unfold, frictionally cleaning the surface of the dispensing port, effectively removing the residual glue on the surface. This automatic cleaning process greatly improves the production efficiency, reduces the need for manual operation, and reduces the labor intensity.

[0016] 2. In this solution, by providing a glue removing mechanism, the cleaning needle is driven to rotate inside the dispensing port by the bidirectional motor. The solidified colloid is hooked by the barbs on its surface and driven to rotate, thereby disconnecting the adhesion between the colloid and the inner surface of the dispensing port. When the dispensing valve body is pulled out of the device, the colloid can be separated from the inside of the dispensing valve body together with the cleaning needle, effectively avoiding the problem of internal blockage.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1 to 6 , an automatic glue wiping assembly for a dispensing valve, including a housing 1, a dispensing valve body 2 is arranged above the housing 1, a dispensing port 3 is fixedly installed at the bottom of the dispensing valve body 2, a jack 4 matching with the dispensing port 3 is opened on the upper surface of the housing 1, two motor boxes 6 are opened on both sides of the housing 1, the inside of the two motor boxes 6 is communicated with the inside of the housing 1, a door that can be opened is arranged on one side of the motor box 6, a needle storage box 5 is fixedly installed on the bottom surface of the housing 1, an anti-slip plate is arranged on the bottom surface of the needle storage box 5, a rotatable rotating plate 12 is arranged on the bottom surface of the needle storage box 5, a filling hole is opened at the center of the rotating plate 12, a nail mounting tube 13 is fixedly connected to one side surface of the rotating plate 12, and a rotatable rotating cover plate 21 is connected to the other side of the rotating plate 12 through a rotating shaft, and a cleaning mechanism is arranged inside the housing 1;

[0026] The cleaning mechanism includes: a cloth winding roller 7 and a cloth receiving roller 10. The cloth winding roller 7 and the cloth receiving roller 10 are arranged on the upper surfaces of two motor boxes 6. A driving motor is arranged inside the motor box 6. A two-way motor 9 is arranged inside the motor box 6 below the cloth winding roller 7. A coupling 17 is arranged on the bottom output shaft of the two-way motor 9. There are two mutually matching couplings 17, and a transmission belt 18 is connected between the two couplings 17. A cleaning cloth 8 is connected between the cloth winding roller 7 and the cloth receiving roller 10. The cleaning mechanism further includes a fixing plate 16. The side surface of the fixing plate 16 is fixedly installed on the inner side wall of the housing 1. Two limiting platforms are fixedly installed on the other side surface of the fixing plate 16. Circular holes opposite to the jacks 4 are opened on the surfaces of the two limiting platforms. A rotatable connecting sleeve 22 is arranged between the two limiting platforms. The cleaning cloth 8 is sleeved on the outer surface of the connecting sleeve 22;

[0027] A degumming mechanism is fixedly installed on the inner bottom surface of the housing 1. The degumming mechanism includes: a needle table 14. A rotatable cleaning needle 15 is arranged at the center of the needle table 14. A plurality of barbs 23 are arranged on the surface of the cleaning needle 15. A filling hole matched with the rotating plate 12 is opened on the bottom surface of the needle table 14. A slidable movable plate 20 is arranged on the bottom surface of the needle table 14. A rotating disc is arranged at the center of the movable plate 20. A chute 19 matched with the movable plate 20 is opened on the bottom surface of the housing 1. One side of the movable plate 20 is connected with an electric push rod 11 that can be driven. The electric push rod 11 is fixedly installed on the inner bottom surface of the housing 1.

[0028] During use, the operator installs the dispensing valve body 2 above the housing 1. The dispensing port 3 extends into the interior of the housing 1 through the jack 4 and is fixed using the connecting sleeve 22. The needle storage box 5 is installed on the bottom surface of the housing 1. The cleaning cloth 8 is wound around the cloth roller 7, passes through the connecting sleeve 22, and is finally connected to the cloth take-up roller 10. The cleaning needle 15 is inserted by the operator by flipping the rotating plate 12, turning one side of the nail loading tube 13 into the interior of the needle storage box 5, and opening the rotating cover plate 21 by rotation to expose the filling hole. The unused cleaning needle 15 is inserted through the filling port. After the cleaning needle 15 enters the interior of the needle table 14, the rotating plate 12 is flipped so that the nail loading tube 13 is located at the bottom surface of the dispensing valve body 2, and the rotating cover plate 21 is flipped to the bottom surface of the needle table 14. The movable plate 20 is slid inside the chute 19 by driving the electric push rod 11 to block the bottom surface of the needle table 14. At this time, the bottom surface of the cleaning needle 15 fits against the turntable on the top surface of the coupling 17 under the action of gravity. The electric push rod 11, the bidirectional motor 9, and the driving motor are all in a standby state. During the glue cleaning process, when the dispensing valve needs to perform a glue cleaning operation, the driving motor is started to drive the cloth roller 7 to rotate, causing the cleaning cloth 8 to gradually stretch at one end and pass over the surface of the connecting sleeve 22 before being wound onto the surface of the cloth take-up roller 10. During the movement of the cleaning cloth 8, the surface of the dispensing port 3 inside the connecting sleeve 22 is frictionally cleaned to remove the residual glue on the surface. During the process of the bidirectional motor 9 driving the cloth roller 7 to rotate, the coupling 17 at the bottom of the bidirectional motor 9 starts to rotate synchronously, and the cleaning needle 15 starts to rotate with the rotating disk using the transmission effect of the transmission belt 18. Due to the restrictive effect of the fixing plate 16, during the cleaning process, the cleaning needle 15 is located inside the opening at the bottom of the dispensing port 3 and pierces into the solidified colloid inside the dispensing port 3. The barbs 23 on the side surface of the cleaning needle 15 are used to hook the colloid. As the cleaning needle 15 rotates, the cleaning needle 15 can drive the colloid to rotate inside the dispensing port 3, disconnecting the adhesive effect between the colloid and the inner surface of the dispensing port 3. When the dispensing valve body 2 is withdrawn from the interior of the housing 1 after cleaning, the cleaning needle 15 can hook out the colloid from the interior of the dispensing port 3, avoiding the problem of internal blockage. After use, the movable plate 20 is moved by driving the electric push rod 11, causing the needle table 14 to fall out of the interior of the needle table 14 under gravity and fall into the interior of the dispensing valve body 2 for storage, and a new cleaning needle 15 is loaded for use the next time.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
