[0035] The pushing assembly includes a slide rod 15, multiple groups of linkage components, a support frame 16 and an electric telescopic cylinder 17. The support frame 16 is vertically fixedly installed at the bottom end of the shell 1, and the electric telescopic cylinder 17 is vertically fixedly installed at the bottom end of the support frame 16.

The bottom end of the slide rod 15 is rotatably connected to the top end of the electric telescopic cylinder 17. The multiple groups of linkage components are divided into two groups and are symmetrically arranged on both sides of the slide rod 15.

[0036] The linkage components include a connecting rod 18, two connecting members 19, a support plate 20 and a support rod 21. Both ends of the connecting rod 18 are hinged to the side of the sliding rod 15 and the inner side of the first scraper rod 4 through the connecting member 19. The support plate 20 is horizontally fixed on the inner wall of the central axis 3 and is hinged to the middle part of the connecting rod 18 through the support rod 21.

[0037] A spring 22 is fixedly installed between the outer side of the bottom of the second scraper rod 5 and the side wall of the slide groove 9, a first sliding opening 23 is horizontally opened at the bottom end of the insert block 7, a push rod 24 is vertically fixedly installed at the bottom end of the second scraper rod 5, and a roller 25 is rotatably installed at the bottom end of the push rod 24.

The inner wall of the sliding platform 27 is fixedly connected to the slide rod 15 through two cross bars 28, and the two cross bars 28 are slidably installed in the two second sliding openings 26 respectively.

[0038] The shell 1 is made of insulating material, and electromagnetic heating is performed between the coil 11 and the gun head. The two electrode rings 12 connect the central axis 3, the plug 7, the second scraper 5, the connector 19, the connecting rod 18 and the first scraper 4 to the circuit, and have an electric heating function.

[0039] The rotating assembly includes a motor 29, a first gear 30 and a second gear 31. The motor 29 is fixedly mounted at the bottom end of the housing 1. The first gear 30 is fixedly sleeved on the output shaft end of the motor 29. The second gear 31 is fixedly sleeved on the central shaft 3 and meshed with the first gear 30.

[0040] The clamping mechanism includes a driving component and three sets of clamping components. The clamping components include a guide rail 32, a clamping block 33, a screw 34 and a clamping frame 35. The guide rail 32 is fixedly mounted on the top of the shell 1, the clamping block 33 is slidably embedded in the guide rail 32, the screw 34 is horizontally threaded in the clamping block 33, the clamping frame 35 is vertically fixed on the outer end of the guide rail 32, the screw 34 is rotatably sleeved in the clamping frame 35, and the three screws 34 are connected by a driving component.

[0041] The driving component includes a ring body 36, three third gears 37 and a ring gear 38. The ring body 36 is rotatably sleeved on the upper side of the shell 1, and the ring gear 38 is fixedly installed on the top of the ring body 36. The three third gears 37 are respectively fixedly sleeved on the tail ends of the three screws 34 and are all engaged with the ring gear 38.

[0042] When using this device to clean the glue gun head, the top of the shell 1 is placed on the glue gun head, and then the ring body 36 is rotated. The ring body 36 drives the ring gear 38 to rotate, and the ring gear 38 drives multiple third gears 37 to drive the screw 34 to rotate, so that the three clamping blocks 33 move at the same time, clamping the glue gun head to achieve fixation.

[0043] After the glue gun head is clamped, the central axis 3 is inside the glue gun, and the side wall of the glue gun is between the first scraper 4 and the second scraper 5. After power is turned on, the coil 11 passes current, and under the action of the electromagnetic, the gun head is heated. After a period of time, the electric telescopic cylinder 17 shortens, driving the slide bar 15 to move downward. The slide bar 15 drives multiple connecting rods 18 to deflect through the connecting piece 19, so that the two first scrapers 4 are pushed out and contact the inner wall of the glue gun head. The slide bar 15 moves downward and drives the slide 27 to move downward through the two cross bars 28, releasing the pushing force on the roller 25. The spring 22 extends, pushing the second scraper 5 close to the central axis 3 and contacting the outer wall of the gun head.

[0044] After the first scraper 4 contacts the inner wall of the gun head and the second scraper 5 contacts the outer wall of the gun head, the motor 29 and the suction device 2 are started to perform the cleaning operation. The motor 29 rotates, and the second gear 31 is driven to rotate through the first gear 30. The second gear 31 drives the central axis 3 to rotate. The central axis 3 drives the plug block 7 and the connecting rod 18 to rotate. The plug block 7 drives the second scraper 5 to rotate, and the connecting rod 18 drives the first scraper 4 to rotate, thereby achieving simultaneous cleaning of the inside and outside of the glue gun head to ensure sufficient cleaning.

[0045] During cleaning, the coil 11 heats the gun head, and the electrode ring 12 heats the first scraper 4 and the second scraper 5. The inside and outside of the gun head are fully heated, thereby fully heating and melting the residual glue, making it easier to clean.

[0046] When the suction device 2 is in operation and the cleaning operation is performed, a suction effect is generated. Under the suction effect, the first scraper 4 scrapes the residual glue on the inner wall and enters the interior of the central axis 3 through the first suction port 6. The second scraper 5 melts and scrapes the residual glue on the outside and enters the guide cavity 8 through the second suction port 10. Then, it enters the hose 14 through the guide cavity 8, and then enters the interior of the central axis 3 through the hose 14, and finally enters the suction device 2 through the bent pipe 13, thereby achieving timely cleaning of the residual glue.

[0047] After the cleaning operation is completed, the electric telescopic cylinder 17 is extended, causing the slide rod 15 to move upward, the two first scraper rods 4 to be retracted into the first suction port 6, and the slide 27 to move upward, causing the two push rods 24 to move away from each other, thereby driving the second scraper rods 5 to move away from each other and reset, and then the ring body 36 is rotated in the opposite direction to achieve unlocking, completing the entire operation process, and the next gun head can be cleaned.

[0048] When the device is combined with the gun head, the clamping mechanism clamps the gun head, and the two first scrapers 4 and the second scraper 5 further clamp the gun head to ensure the firmness of the combination and full contact with the gun head, further ensuring the adequacy of cleaning and improving efficiency.

[0049] Each electrical device is powered by an external power supply. The circuit connection belongs to the existing mature technology, and its electrical connection relationship and specific circuit structure are not described in detail here.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
