[0032] As attached Figure 1-7 The glue gun with a cleaning mechanism shown includes a glue gun body 1, a wiping component and a cleaning component.

[0033] The wiping assembly includes a linear drive module 21, a workbench 22 and a cleaning claw 23; the linear drive module 21 is installed on the side of the glue gun body 1, the workbench 22 is fixedly connected to the linear drive module 21, the cleaning claw 23 is rotatably installed on the workbench 22, one end of the cleaning claw 23 is fixedly connected to a swing gear 231, the glue gun body 1 is provided with a rack 11 meshing with the swing gear 231, the linear drive module 21 makes the workbench 22 move up and down in the vertical direction, so that the swing gear 231 rotates under the action of the rack 11, and then the cleaning claw 23 swings in the direction close to or away from the glue gun body 1.

[0034] The cleaning assembly includes a liquid storage tank 41 , a cleaning tank 42 and a water pump 44 . The cleaning tank 42 is disposed on the workbench 22 . The liquid storage tank 41 , the cleaning tank 42 and the water pump 44 form a circulation loop.

[0035] The linear drive module 21 can be realized by existing technology and can be realized by existing electric components and transmission components.

[0036] In some embodiments, the liquid storage tank 41 stores corresponding sols according to the type of glue in the glue gun body 1 .

[0037] The workbench 22 is rotatably provided with a first winding wheel 221 and a second winding wheel 222, and the first winding wheel 221 is provided with a cleaning belt 3. The cleaning belt 3 is made of non-woven fabric, and has a rough surface, so as to improve the wiping effect of the glue, and the cleaning belt 3 has good tensile resistance and can withstand repeated wiping without breaking.

[0038] In some embodiments, a filter box 43 is provided between the cleaning box 42 and the circulation loop of the water pump 44, and a filter filler 431 is provided in the filter box 43. The filter filler 431 is made of melt-blown cloth, and the filter filler 431 serves to intercept larger impurities and solidified glue particles to prevent them from entering the circulation loop, which helps to protect the water pump 44 and other components from clogging and damage.

[0039] In some embodiments, a water inlet pipe 45 is connected between the liquid storage tank 41 and the cleaning tank 42, one end of the water inlet pipe 45 is fixedly connected to the top of the inner wall of the cleaning tank 42, a water suction pipe 46 is arranged between the cleaning tank 42 and the filter box 43, one end of the water suction pipe 46 is fixedly connected to the bottom of the inner wall of the cleaning tank 42, and a return pipe 47 is connected between the output end of the water pump 44 and the liquid storage tank 41.

[0040] In some embodiments, a brush roller 421 and a sponge block 422 are provided in the cleaning box 42. The brush roller 421 is rotatably connected to the cleaning box 42, and the cleaning belt 3 passes between the brush roller 421 and the sponge block 422. The brush roller 421 can effectively brush off the dry glue particles attached to the cleaning belt 3. Furthermore, the bristles of the brush roller 421 can penetrate into the texture of the cleaning belt 3 to ensure thorough cleaning. The sponge block 422 is mainly used for adsorption and wiping. The sponge block 422 absorbs the sol, and evenly applies the sol on the cleaning belt 3 when the cleaning belt 3 passes, dissolving and absorbing the uncured glue. The combined use of the brush roller 421 and the sponge block 422 can significantly improve the cleaning effect, ensuring that the cleaning belt 3 always maintains a good cleaning state during the recycling process.

[0041] In some embodiments, the first winding wheel 221 and the second winding wheel 222 are both connected to a motor 225, the housing of the motor 225 is fixedly mounted on the workbench 22, and the motor 225 drives the first winding wheel 221 and the second winding wheel 222 to rotate. Figure 3 As shown, the first winding wheel 221 and the second winding wheel 222 rotate in the same direction, the cleaning tape 3 is released from the first winding wheel 221, passes through the cleaning claw 23 and the cleaning box 42, and then is wound onto the second winding wheel 222, thereby driving the cleaning tape 3 to clean the glue nozzle of the glue gun body 1 from top to bottom. When the glue gun body 1 is in the working mode, as shown in FIG. Figure 4As shown, the motor 225 drives the first winding wheel 221 and the second winding wheel 222 to rotate in the other direction, and starts to rewind the used cleaning tape 3 on the second winding wheel 222 back to the first winding wheel 221 .

[0042] In some embodiments, the cleaning claw 23 is provided with a guide post 232 and a reversing through hole 233 for the cleaning belt 3 to pass through. The guide post 232 is mainly used to guide the cleaning belt 3 so that it maintains a stable and correct path on the cleaning claw 23. Avoid the cleaning belt 3 from deflecting or tying during operation. Through the guide post 232, the cleaning belt 3 can also maintain appropriate tension, ensuring that the cleaning belt 3 is close to the cleaning claw 23 during the wiping process, thereby improving the cleaning effect. The reversing through hole 233 is used to change the running direction of the cleaning belt 3 and reduce the friction between the cleaning belt 3 and other components, thereby extending the service life of the cleaning belt 3.

[0043] In some embodiments, the outer wall of the liquid storage tank 41 is provided with an observation window 411. This allows the operator to conveniently and intuitively monitor the liquid level and state of the sol in the liquid storage tank 41, ensuring that the cleaning component is always in the best working state. This not only improves the cleaning efficiency, but also reduces the risk of failure caused by insufficient sol.

[0044] In some embodiments, the workbench 22 is rotatably provided with a tensioning wheel 224 and an auxiliary wheel 223 acting on the cleaning belt 3. During the recycling process of the cleaning belt 3, the tensioning wheel 224 can effectively prevent the cleaning belt 3 from tangling or winding. By maintaining the appropriate tension of the cleaning belt 3, the tensioning wheel 224 ensures that the cleaning belt 3 can run smoothly when winding and unwinding, avoiding the stuck fault or the reduction of the cleaning effect caused by tangling. The auxiliary wheel 223 helps to reduce the friction between the cleaning belt 3 and other components when the cleaning claw 23 swings.

[0045] Furthermore, in order to make the cleaning more complete, two sets of wiping components and cleaning components are symmetrically arranged with the central axis of the glue gun body 1 as the axis of symmetry.

[0046] The working principle of the utility model is as follows:

[0047] When the glue gun body 1 needs to be wiped and cleaned, the linear drive module 21 moves downward, thereby pushing the workbench 22 to move downward. As the workbench 22 moves, the cleaning claw 23 swings toward the glue gun body 1 under the action of the rack 11 and the swing gear 231, and the cleaning claw 23 abuts against the glue nozzle of the glue gun body 1. Figure 3As shown. At this time, the first winding wheel 221 and the second winding wheel 222 start to rotate, and the cleaning tape 3 is released from the first winding wheel 221, passes through the guide column 232 and the reversing through hole 233 to bypass the cleaning claw 23, and then the cleaning tape 3 wipes the glue nozzle from top to bottom; the cleaning tape 3 after wiping changes direction under the action of the auxiliary wheel 223 and enters the cleaning box 42. In the cleaning box 42, the cleaning tape 3 passes through the brush roller 421 and the sponge block 422 to remove the glue on the cleaning tape 3. Then, after passing through the cleaning box 42, the cleaning tape 3 is wound on the second winding wheel 222.

[0048] When the glue gun body 1 needs to apply glue, the linear drive module 21 moves upward, thereby driving the workbench 22 to move upward. As the workbench 22 moves, the cleaning claw 23 swings away from the glue gun body 1 under the action of the rack 11 and the swing gear 231, and finally the cleaning claw 23 is in a position perpendicular to the side wall of the glue gun body 1, which does not affect the normal operation and discharging of the glue gun body 1. Figure 4 As shown. At this time, the cleaning assembly starts to clean the cleaning belt 3. The motor 225 rotates in the other direction to rewind the cleaning belt 3 on the second winding wheel 222 back to the first winding wheel 221. Thus, the cleaning belt 3 passes through the cleaning box 42, the brush roller 421 and the sponge block 422 again for secondary cleaning, ensuring that the cleaning belt 3 is thoroughly cleaned before the next use. During this process, the water pump 44 remains in the started state, ensuring that the sol in the cleaning box 42 is in a circulating state, thereby helping to improve the cleaning effect.

[0049] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
