[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a drip-proof hot melt glue machine, including a hot melt glue machine nozzle 1. A protective component for protecting the hot melt glue machine during operation is installed on the front side of the hot melt glue machine nozzle 1. The protective component includes an outer ring 2. An installation component for fixing the protective component is installed on the outer wall of the outer ring 2. A collection component for collecting hot melt glue is installed at the bottom of the outer ring 2. The protective component also includes a plug groove 21 for plugging into the outer ring 2. The plug groove 21 is opened at the front end of the outer wall of the hot melt glue machine nozzle 1. A baffle 22 is fixedly connected to the bottom of the front end of the outer wall of the outer ring 2. The baffle 22 is designed to be inclined.

[0023] Through the above technical solution, the main body of the protective component is ring-shaped, which works together with the inclined baffle 22 to prevent residual hot melt glue from dripping into the working environment when the hot melt glue machine is working. The insertion groove 21 needs to have a certain depth to ensure that the outer ring 2 can be stably inserted, and at the same time, it can be easily disassembled and assembled by personnel according to actual usage needs. This structure is composed of multiple components, which ensures the multifunctionality and ease of use of the device.

[0024] Please see Figures 3-6The installation assembly includes multiple locking blocks 3, which are arranged in a ring array around the center of the outer ring 2 on the right end of the outer wall of the outer ring 2. The inner wall of the hot melt glue machine nozzle 1 is provided with multiple cavities 31 at equal intervals near the insertion slot 21. Springs 32 are fixedly connected to both sides of the inner wall of the cavity 31. The end of the spring 32 is fixedly connected to a locking post 33, which is adapted to the concave side of the locking block 3. The collection assembly includes multiple through holes 4 arranged in a rectangular array. The through holes 4 are opened at the front end of the bottom wall of the outer ring 2. A fixing block 43 is fixedly connected to the front end of the bottom wall of the outer ring 2. A second magnetic block 44 is fixedly connected to the front end of the outer wall of the fixing block 43. A first collection box 41 is slidably connected to the front end of the bottom wall of the outer ring 2. A first magnetic block 42 is fixedly connected to the rear end of the outer wall of the first collection box 41. The first magnetic block 42 and the second magnetic block 44 are magnetically attracted to each other.

[0025] Through the above technical solution, the protective component is inserted into the inner side of the two locking posts 33 by the locking block 3, and the locking block 3 is limited by the elastic force of the spring 32. At the same time, it can be quickly removed by personnel pulling it, which improves the convenience of disassembly and assembly while ensuring the stable installation of the protective component. The inclined baffle 22 is close to the through hole 4, so as to ensure that the dripping hot melt glue falls into the second collection box 7 through the through hole 4, and achieves centralized collection.

[0026] Please see Figure 3 and Figure 4 The outer ring 2 has slots 8 on both the left and right ends of its outer wall, and anti-slip textures 9 on the inner wall of the slots 8. Multiple positioning posts 5 are arranged in a ring array around the center of the outer ring 2 on the rear side of the inner wall of the outer ring 2. Positioning grooves 6 are provided on the inner wall of the hot melt glue machine nozzle 1 at the positions corresponding to the positioning posts 5. The positioning posts 5 are slidably connected to the inner wall of the positioning grooves 6. A second collection box 7 is installed on the inner wall of the first collection box 41. The second collection box 7 is made of polytetrafluoroethylene material.

[0027] Through the above technical solution, the slots 8 and anti-slip textures 9 on both sides of the outer wall of the outer ring 2 facilitate the installation and removal of the outer ring 2 by personnel; the design of the positioning post 5 and the positioning groove 6 can ensure the accuracy of the installation position when installing the outer ring 2, and ensure that the locking block 3 can be stably inserted into the cavity 31; since polytetrafluoroethylene has excellent high temperature resistance and non-stick properties, the inner wall of the second collection box 7 is made of polytetrafluoroethylene material, which can prevent hot melt adhesive from adhering to the inner wall of the collection box and ensure the convenience of pouring out the hot melt adhesive.

[0028] Working principle: A slot 21 is opened at the front end of the outer wall of the hot melt glue machine nozzle 1. The positioning post 5 is aligned with the positioning slot 6, and then the outer ring 2 is inserted into the slot 21 to ensure the accuracy of the installation position of the outer ring 2. The locking block 3 moves into the cavity 31, pressing the locking post 33 and moving it inward by the elastic force of the spring 32 until the concave side of the locking block 3 engages with the locking post 33, ensuring the stability of the installation of the outer ring 2. When the hot melt glue machine is in use, the dripping hot melt glue falls on the surface of the baffle 22 and then continues to slide down through the through hole 4 into the interior of the first collection box 41. A second collection box 7 made of polytetrafluoroethylene is installed to prevent hot melt adhesive from remaining in the second collection box 7, making it easier for personnel to collect and reuse the hot melt adhesive in the box, thus improving resource utilization. The first collection box 41 is slidably connected to the bottom wall of the outer ring 2 through a plug-in groove. When the hot melt adhesive in the second collection box 7 is full, the first magnetic block 42 and the second magnetic block 44 on the outer wall of the first collection box 41 and the fixing block 43 are separated, and then it is taken out from the bottom wall of the outer ring 2. The above structure allows for quick assembly and disassembly of the collection components, improving the convenience of using the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
