Description

Technical Field

[0001] This utility model relates to the field of hot melt glue gun technology, specifically a kneading gun for hot melt glue. Background Technology

[0002] Hot melt glue kneading guns, commonly known as hot melt glue machines, are widely used in electronics factories, food factories, packaging plants, and other places to bond products using hot melt glue sticks. This tool works by using electric heating to melt the hot melt glue sticks. The hot melt glue sticks, the main material of the hot melt glue gun, are solid at room temperature. When heated to a certain temperature, they melt into a fluid adhesive. Once removed from the heating element, they cool and solidify rapidly, resulting in very fast bonding. However, when using hot melt glue kneading guns, the gun body is often placed directly on a table, and the molten fluid at the glue nozzle easily comes into contact with the table surface, making it dirty. Existing hot melt glue kneading guns typically have a foldable support frame under the glue nozzle. When not in use, the support frame is opened, and the gun body is stood upright on the table using the support frame and the bottom of the handle, as shown in the attached diagram in the instruction manual. Figure 1 As shown, due to the limited contact area between the support frame and the table, the gun body is easily knocked over by accident or blown over by the wind, and the gun head may still come into contact with the table. Utility Model Content

[0003] This invention provides a kneading gun for hot melt adhesives to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A kneading gun for hot melt adhesive includes a gun body and a handle. The left and right ends of the gun body are respectively provided with an inlet and an outlet. The handle is provided with a pressure trigger. The outer surface of the gun body is provided with a protective sleeve, which is rotatably fitted around the outlet.

[0006] As a further embodiment of this utility model: a fixed shaft is fixedly connected to both the front and rear surfaces of the gun body, one end of the protective sleeve is sleeved on the surface of the fixed shaft, a torsion spring is sleeved on the surface of the fixed shaft, and the two ends of the torsion spring are respectively fixedly connected to the surface of the fixed shaft and the surface of the protective sleeve.

[0007] As a further embodiment of this utility model: an extension block is fixedly connected to the upper surface of the gun body, a sliding block is slidably disposed inside the extension block, a blocking block is fixedly connected to the right side of the sliding block, and the right end of the blocking block extends to the outside of the extension block, one end of the protective sleeve away from the fixed shaft abuts against the lower surface of the blocking block, a spring is fixedly connected to the left end of the sliding block, the other end of the spring is fixedly connected to the inner wall of the extension block, side grooves are formed on the front and rear side surfaces of the extension block, and push buttons are fixedly connected to both the front and rear surfaces of the sliding block, the push buttons passing through the side grooves and extending to the outside of the extension block.

[0008] As a further improvement of this utility model, the upper surface of the right end of the blocking block is set at an angle.

[0009] As a further improvement of this utility model: a limiting block is fixedly attached to the front and rear side surfaces of the gun body, the limiting block is located close to the dispensing nozzle, and the limiting block is located on the lower side of the fixed shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By setting a rotatable protective sleeve, the nozzle can be shielded to prevent it from contacting and contaminating the table. The hot melt glue gun can also be placed horizontally on the table, which eliminates the possibility of accidentally knocking over the gun and causing the nozzle to hit the table compared to traditional hot melt glue guns with a support structure. Furthermore, the rotatable design of the protective sleeve makes the operation simple and prevents it from falling off easily. Attached Figure Description

[0018] Please see Figures 2-5 In this embodiment of the utility model, a kneading gun for hot melt adhesive includes a gun body 1 and a handle 2. The left and right ends of the gun body 1 are respectively provided with an inlet 4 and an outlet 3. The handle of the handle 2 is provided with a pressure trigger 15. The gun body 1 is characterized by having a protective sleeve 5 on its outer surface, and the protective sleeve 5 is rotatably fitted on the outside of the outlet 3.

[0019] Preferably, a fixed shaft 6 is fixedly connected to both the front and rear surfaces of the gun body 1, one end of the protective sleeve 5 is sleeved on the surface of the fixed shaft 6, a torsion spring 7 is sleeved on the surface of the fixed shaft 6, and the two ends of the torsion spring 7 are respectively fixed to the surface of the fixed shaft 6 and the surface of the protective sleeve 5.

[0020] Preferably, an extension block 9 is fixedly connected to the upper surface of the gun body 1, a sliding block 12 is slidably disposed inside the extension block 9, a blocking block 10 is fixedly connected to the right side of the sliding block 12, and the right end of the blocking block 10 extends to the outside of the extension block 9. The end of the protective sleeve 5 away from the fixed shaft 6 abuts against the lower surface of the blocking block 10. A spring 13 is fixedly connected to the left end of the sliding block 12, and the other end of the spring 13 is fixedly connected to the inner wall of the extension block 9. Side grooves 14 are opened on the front and rear side surfaces of the extension block 9. Push buttons 11 are fixedly connected to both the front and rear surfaces of the sliding block 12. The push buttons 11 pass through the side grooves 14 and extend to the outside of the extension block 9.

[0021] Preferably, the upper surface of the right end of the blocking block 10 is sloped.

[0022] Preferably, a limiting block 8 is fixed to the front and rear side surfaces of the gun body 1, the limiting block 8 is located near the dispensing nozzle 3, and the limiting block 8 is located on the lower side of the fixed shaft 6.

[0023] The working principle of this utility model is as follows: When using the hot melt glue kneading gun, the hot melt glue stick is installed from the glue stick inlet 4. After turning on the hot melt glue kneading gun, the molten fluid is squeezed out from the glue outlet 3 by pressing the glue pressing trigger 15. When the use of the hot melt glue kneading gun is stopped, the push button 11 is pushed to the left, so that the blocking block 10 no longer blocks the upper side of the protective sleeve 5. Under the torsional force of the torsion spring 7, the protective sleeve 5 can rotate and be placed on the outside of the glue outlet 3 for protection. Since the surface of the gun body 1 is provided with a limiting block 8, when the protective sleeve 5 rotates to the outside of the glue outlet 3, the limiting block 8 forms a shape on the protective sleeve 5. The protective sleeve 5 is stopped by the blocking mechanism. At this time, the hot melt glue gun can be placed horizontally on the table. The glue nozzle 3 will not touch the table or any objects on the table. When the hot melt glue gun needs to be used again, the protective sleeve 5 is rotated in the opposite direction so that the protective sleeve 5 rotates back to the outside of the gun body 1. Since the upper surface of the blocking block 10 is set at an angle, after contacting the protective sleeve 5, the blocking block 10 can be squeezed and pushed into the interior of the extension block 9. When the protective sleeve 5 rotates to the lower side of the blocking block 10, under the pushing force of the spring 13, the blocking block 10 blocks the protective sleeve 5 and restricts it. The outside of the glue nozzle 3 is not blocked and can be used normally.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
