[0018] 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.

[0019] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a hot melt adhesive machine with a cleaning function, including a machine body 1. The machine body 1 is equipped with a cleaning component for scraping and cleaning hot melt adhesive. The top wall of the machine body 1 is equipped with a drive component for driving the cleaning component to work. The drive component includes a mounting frame 3. The bottom wall of the mounting frame 3 is equipped with a motor 31. The machine body 1 is equipped with a stirring component for stirring the hot melt adhesive. The stirring component rotates synchronously with the cleaning component. The cleaning component includes a scraper 2. The size of the scraper 2 is adapted to the inner wall of the machine body 1. The top of the scraper 2 is fixedly connected to a first rotating gear 21. The top wall of the machine body 1 is provided with a rotating groove 22. The scraper 2 is rotatably connected to the inner wall of the rotating groove 22.

[0020] Through the above technical solution, the motor 31 is installed on the top wall of the mounting frame 3. The motor 31 drives multiple gears to rotate, ultimately achieving synchronous rotation of the cleaning component and the stirring component. The scraper 2 of the cleaning component needs to be compatible with the inner wall of the machine body 1 and should be made of a non-stick hot melt adhesive material. Stainless steel can be selected or a Teflon coating can be applied to the outer surface of the scraper 2 to prevent the hot melt adhesive from solidifying on its surface and affecting subsequent use.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The drive assembly also includes a drive gear 32, which is fixedly connected to the output end of the motor 31. A second rotating gear 33 is meshed with the outer wall of the drive gear 32. The second rotating gear 33 and the first rotating gear 21 are fixedly connected. A gear ring 34 is fixedly connected to the top wall of the body 1. The first rotating gear 21 and the gear ring 34 are meshed with each other. The stirring assembly includes a support rod 4. The top end of the support rod 4 is fixedly connected to the bottom wall of the drive gear 32. The bottom end of the support rod 4 is rotatably connected to the inner bottom wall of the body 1. Multiple stirring racks 41 are arranged in a ring array around the center of the support rod 4 on the outer wall of the support rod 4.

[0022] Through the above technical solution, the second rotating gear 33 needs to be larger in size, and one side needs to extend to the top wall of the gear ring 34, so as to ensure that the first rotating gear 21 and the second rotating gear 33 have enough support points to achieve stable rotation; the stirring frame 41 is composed of multiple bow-shaped rods connected end to end, and like the scraper 2, its outer surface is coated with a non-stick layer, and it is used in conjunction with the cleaning component to stir the hot melt adhesive.

[0023] Please see Figure 1 and Figure 2 The stirring rack 41 is composed of multiple bow-shaped rods arranged in a ring array and connected end to end. The outer surface of the stirring rack 41 is coated with a non-stick layer made of Teflon material. The control panel 5 is installed at the front end of the outer wall of the body 1. The control panel 5 is electrically connected to the motor 31. Multiple support feet 6 are fixedly connected at equal intervals at the bottom of the outer wall of the body 1. Self-locking wheels 7 are installed on the bottom wall of the support feet 6.

[0024] Through the above technical solutions, Teflon exhibits excellent non-stick properties and good chemical stability. It can withstand the erosion of strong acids, strong alkalis, and other chemicals. During the hot melt adhesive production process, even if the adhesive solution contains some corrosive additives, the Teflon coating remains stable and will not chemically react with the adhesive solution, ensuring stirring efficiency. The device uses a control panel 5 to centrally control the electrical equipment within, ensuring the stability of the device's operation. The machine body 1 achieves support and movement through support feet 6 and self-locking wheels 7, improving the ease of use of the device.

[0025] Working principle: The machine body 1 is supported and installed by multiple support feet 6 at the bottom. The motor 31 installed on the bottom wall of the mounting frame 3 is started through the control panel 5. The motor 31 drives the drive gear 32 to rotate, and the drive gear 32 drives the second rotating gear 33 to rotate synchronously. Since the first rotating gear 21 and the second rotating gear 33 are fixedly connected, the second rotating gear 33 drives the first rotating gear 21 to rotate synchronously. The first rotating gear 21 is also engaged with the gear ring 34, thus ensuring that the first rotating gear 21 and the second rotating gear 33 have a stable fulcrum to make circular motion around the outer wall of the drive gear 32. At the same time, the scraper 2 drives the scraper 2 to scrape the inner wall of the machine body 1 to achieve the cleaning effect. The two ends of the support rod 4 are fixedly connected to the inner top wall of the machine body 1 and rotatably connected to the inner bottom wall of the machine body 1, respectively. This can drive the multiple stirring racks 41 on the outer wall to stir the hot melt adhesive inside the machine body 1. Therefore, the drive component can drive the cleaning component and the stirring component to work simultaneously, ensuring the speed of cleaning the inner wall of the machine body 1 and facilitating operation by personnel.

[0026] 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.
