Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a glue gun which is easy to clean. Background Art

[0002] A glue gun is a device used to spray or inject adhesive onto the surface of an object under pressure. A glue gun is a tool for applying glue (or squeezing glue). It may be used wherever glue is needed. It is widely used in industries such as building decoration, electronic appliances, automobiles and automobile parts, ships and containers. Classification by force: manual glue gun, pneumatic glue gun, electric glue gun. Manual glue gun: The operator presses the plate with his hands to apply glue. The efficiency of gluing is low. It is designed for professionals or families who do not use it frequently. Pneumatic glue gun: It needs to be connected to a compressed air source, and the air pushes the bottom of the glue to achieve gluing. Electric glue gun: The electric glue gun is powered by a rechargeable battery. It is equipped with a charger and a rechargeable battery, which can easily complete a large amount of gluing work. The gluing head of an existing gluing gun is generally exposed to the air. When the machine stops working, the glue adhering to the glue head is easily solidified, which causes the gluing head to become blocked. The glue gun cannot effectively and quickly spray the glue when it is subsequently used, affecting the use of the glue gun. It is inconvenient to effectively clean the blockage. When the glue gun is working, the gluing head is often in direct contact with the outside world, which makes the glue liquid easily contaminated after contact with the outside world. After the glue liquid flows back, it affects the quality of the glue liquid in the gun body, thereby causing the quality of the glue liquid inside the glue gun body to decline, thereby reducing the effect of the glue liquid use.

[0021] In this embodiment, the glue gun body 1, the glue outlet bucket 21, and the gun head 29 are connected, the sleeve 24 is limited to the outer position of the ring 23, the first return spring 26 is located on the outer side of the fixed cylinder 22, several groups of circular holes 27 are evenly arranged in a circle, several groups of balls 28 are limited to move on the inner positions of several groups of circular holes 27, and the gun head 29 is adapted to the fixed cylinder 22.

[0022] Specifically, when there is glue blockage inside the gun head 29, the sleeve 24 is pushed backward, so that the pressure ring 25 compresses the first return spring 26 and moves to the side of the ring 23, so that the pressure ring 25 leaves the pressure on the several groups of balls 28, and the gun head 29 is pulled out to the front side, so that the several groups of balls 28 leave the inner side of the groove 210 and enter the several groups of round holes 27. The sleeve 24 restricts the outer sides of the several groups of balls 28 to prevent them from spilling out, and the gun head 29 is removed. When the gun head 29 is blocked, the gun head 29 can be quickly removed, which is convenient for effective cleaning, and does not affect the subsequent use of the glue gun body 1. The glue gun body 1 and the glue outlet hopper 21 can also be disassembled by threads, which is conducive to the cleaning of various details inside the glue gun and reduces cleaning blind spots.

[0023] In this embodiment, the isolation mechanism 3 includes a fixed plate 31 fixedly arranged on the inner side of the gun head 29 near the front side, a limiting ring 32 is fixedly arranged on the inner side of the gun head 29 near the rear side of the fixed plate 31, a movable plate 33 is movably connected to the front end of the limiting ring 32, a second reset spring 34 is fixedly connected between the fixed plate 31 and the movable plate 33, a protrusion 35 is fixedly arranged at one end of the movable plate 33 near the limiting ring 32, a sealing ring is fixedly arranged at the position of the movable plate 33 corresponding to the limiting ring 32, and the movable plate 33 and the protrusion 35 are movably arranged on the inner side of the gun head 29 for limiting movement.

[0024] Specifically, first use the glue gun body 1 to push the glue toward the protrusion 35, so that the protrusion 35 pushes the movable piece 33, and the movable piece 33 compresses the second return spring 34, so that the movable piece 33 leaves the fit with the limiting ring 32, and the glue can be discharged from the side of the protrusion 35 to the front side of the movable piece 33, and finally discharged. When the gluing is completed, according to the elastic action of the second return spring 34, the movable piece 33 and the limiting ring 32 will be immediately pushed to fit together to achieve a seal, thereby preventing the glue from flowing back to the glue outlet hopper 21 and the gun head 29 after contact with the outside world, avoiding contamination of the remaining glue inside the glue gun body 1, the glue outlet hopper 21, and the gun head 29, thereby ensuring the quality of the glue inside the glue gun body and improving the subsequent use of the glue.

[0025] Working principle:

[0026] When in use, first use the glue gun body 1 to push the glue toward the protrusion 35, so that the protrusion 35 pushes the movable piece 33, and the movable piece 33 compresses the second return spring 34, so that the movable piece 33 leaves the fit with the limiting ring 32, and the glue can be discharged from the side of the protrusion 35 to the front side of the movable piece 33 and finally discharged. When the glue is applied, according to the elastic effect of the second return spring 34, the movable piece 33 and the limiting ring 32 will be immediately pushed to fit together to achieve a seal, thereby preventing the glue from contacting the outside world from flowing back into the glue outlet hopper 21 and the gun head 29, avoiding the contamination of the remaining glue inside the glue gun body 1, the glue outlet hopper 21, and the gun head 29, thereby ensuring the quality of the glue inside the glue gun body and improving the subsequent use of the glue. When there is glue blockage in the part, the sleeve 24 is pushed backward, so that the pressure ring 25 compresses the first return spring 26 and moves to the side of the circular ring 23, so that the pressure ring 25 leaves the pressure on the several groups of balls 28, and the gun head 29 is pulled out to the front side, so that the several groups of balls 28 leave the inner side of the groove 210 and enter the several groups of circular holes 27. The sleeve 24 restricts the outer sides of the several groups of balls 28 to prevent them from spilling out, and the gun head 29 is removed. When the gun head 29 is blocked, the gun head 29 can be quickly removed, which is convenient for effective cleaning, and does not affect the subsequent use of the glue gun body 1. The glue gun body 1 and the glue outlet hopper 21 can also be disassembled by threads, which is conducive to cleaning various details inside the glue gun and reducing cleaning dead corners.
