[0002] Hot melt adhesive is a thermoplastic adhesive that is solid at room temperature but liquefies at higher temperatures. The melting temperature of hot melt adhesive is generally between 65°C and 180°C. After heating, it can flow and has a certain viscosity, capable of wetting the surface of the substrate, and hardens to form a firm bond after cooling. Hot melt adhesive is non-toxic and odorless, and is regarded as an environmentally friendly chemical product. It has a wide range of applications, including multiple fields such as home decoration, handicrafts, packaging, shoe and hat manufacturing, and furniture. When producing hot melt adhesive, a hot melt adhesive machine (extruder) is required for extrusion.

[0003] Traditional hot melt adhesive machines mostly use mechanical extrusion, and the discharge port does not have a temperature adjustment function, so it is impossible to select to extrude the colloid or solid according to requirements, and the discharge port cannot be adjusted in multiple directions, which limits the scope of application and reduces the convenience of using the hot melt machine. Summary of the Utility Model

[0005] The utility model relates to a hot melt adhesive machine that is convenient for extruding hot melt adhesive, including a hot melt adhesive extruder and an extrusion pipe. The extrusion pipe is fixedly installed at the discharge port of the hot melt adhesive extruder, and a temperature adjustment component and an adjustment component are provided on the extrusion pipe;

[0006] The temperature adjustment component includes an electric push rod and a vortex tube. The electric push rod is fixedly installed at the outer end of the extrusion pipe, and a shaft seat is fixedly installed at the movable end of the electric push rod.

The vortex tube 302 is fixedly inserted into the pipe sleeve 305. During use, the driving motor 304 drives the pipe sleeve 305 to rotate, and the rotation of the pipe sleeve 305 drives the vortex tube 302 to rotate to adjust the positions of the cold air port 306 and the hot air port 307, and the telescopic action of the electric push rod 301 is used to adjust the height of the vortex tube 302 to facilitate switching between cooling and heating;

[0027] The adjusting component 4 includes a flange 401 and a first ball head 402. The flange 401 is fixedly connected to the bottom of the extrusion tube 2. A rotating disk 403 is rotatably installed at the bottom of the flange 401. A plurality of connecting rods 404 are fixedly welded at equal intervals in a circumferential manner at the bottom of the rotating disk 403, and a limiting disk 405 is fixedly welded at the bottom of the connecting rods 404. A connecting pipe 406 is integrally formed at the center of the bottom of the flange 401, and a second ball head 407 is integrally formed at the bottom of the connecting pipe 406. The first ball head 402 is movably sleeved outside the second ball head 407 and is communicated with the second ball head 407. A discharge pipe 408 is integrally formed at the bottom of the first ball head 402. During use, the longitudinal direction and angle of the discharge pipe 408 are adjusted by the movable sleeving action of the first ball head 402 and the second ball head 407, and the horizontal direction is adjusted by the rotating action of the rotating disk 403, which is convenient for adjusting the extrusion direction according to production requirements.

[0028] A support base 101 is fixedly installed at the bottom of the hot melt adhesive extruder 1, and a hopper 102 is fixedly installed on one side of the top. A support rod is fixedly installed between the hot melt adhesive extruder 1 and the extrusion tube 2. During use, the extrusion tube 2 is supported by the support rod, which improves the firmness of the installation of the extrusion tube 2.

[0029] The vortex tube 302 is a "T"-shaped three-way pipe and is provided with a cold air port 306, a hot air port 307, and an air inlet 308.

The air inlet 308 of the vortex tube 302 is connected to an external air compressor pump. Cold air will be ejected from the cold air port 306 and hot air will be ejected from the air inlet 308. The driving motor 304 drives the pipe sleeve 305 to rotate. The rotation of the pipe sleeve 305 drives the vortex tube 302 to rotate to adjust the positions of the cold air port 306 and the hot air port 307. The telescopic action of the electric push rod 301 is used to adjust the height of the vortex tube 302. The vortex tube 302 is communicated with the upper end of the extrusion tube 2 through the sealing cover 309.
