Description

Technical Field

[0001] This application relates to the field of xx processing and production, and in particular to a hot melt adhesive heating and melting device. Background Technology

[0002] Hot melt adhesive is an adhesive that melts when heated and cures when cooled. It is commonly used in various fields such as industrial production, handicrafts, packaging, and furniture manufacturing. It is usually composed of resin, wax, plasticizer, and antioxidant, and has good adhesion and temperature resistance. The main characteristics of hot melt adhesive are that it does not require solvents during the curing process, does not release harmful gases during use, and is simple and convenient to operate, so it is widely used.

[0003] Referring to patent publication number CN212870430U, a heating and melting device for hot melt adhesive raw material particles is disclosed. The device includes a main body, a feeding funnel at the top, a valve at the bottom of the feeding funnel, a cooling box at the bottom inner side of the main body, a third motor on the upper surface of one side of the cooling box, a discharge baffle on one side of the cooling box, and a moving mechanism on the top of one side of the discharge baffle. The device utilizes a designed transmission shaft, drive gear, lead screw, rotating block, and driven gear to facilitate the heating and melting process. During operation, the hot melt adhesive is heated and discharged into the cooling box through the discharge port. Then, the cooled hot melt adhesive is processed into raw material particles by the pushing mechanism. This avoids the cumbersome operation and slow cooling problems of traditional processing methods, greatly improving the processing efficiency and practicality of the heating and melting device.

[0004] Although the above solution can melt the hot melt adhesive raw material, it still has some shortcomings in actual use. For example, because the hot melt adhesive raw material has a certain viscosity after melting, hot melt adhesive is easy to leave residues during actual use, which affects the subsequent production of hot melt adhesive.

[0005] To address this issue, we propose a hot melt adhesive heating and melting device. Utility Model Content

A timer 9 is fixedly installed on the upper surface of the cylinder 1. Two sets of support legs 3 are fixedly installed on the bottom surface of the cylinder 1. The heating time of the raw materials can be recorded by the timer 9, so as to facilitate the operator to control the device.

[0024] A stirring rod 15 is rotatably mounted on the upper surface of the sealing cylinder 11 via bearings. The top end of the stirring rod 15 is fixedly mounted to the output end of the first motor 5. Two threaded tubes 21 are rotatably mounted on the upper surface of the sealing cylinder 11 via two bearings. Each threaded tube 21 has a threaded rod 6 threadedly connected to its inner wall. The two threaded rods 6 extend above the two through holes 4 respectively. A limit ring 20 is fixedly mounted on the top end of each threaded rod 6. The limit ring 20 can limit the threaded rod 6 and prevent it from falling into the interior of the sealing cylinder 11. A push ring 17 is fixedly mounted on the bottom end of the two threaded rods 6. A guide ring 19 is fixedly mounted on the inner wall of the sealing cylinder 11. The bottom surface of the guide ring 19 is fixedly mounted to the inner bottom wall of the sealing cylinder 11. The guide ring 19 can guide the raw material so that it can be discharged in a concentrated manner.

[0025] A scraper ring 22 is fixedly installed on the upper surface of the push ring 17. A worm gear 14 is fixedly installed on the outer surface of each threaded tube 21. Two mounting seats 13 are fixedly installed on the inner wall of the cylinder 1. A second motor 12 is fixedly installed on the left side of one of the mounting seats 13. A worm 10 is fixedly installed at the output end of the second motor 12. The worm 10 meshes with the worm gear 14.

[0026] The working principle of this application is:

[0027] In operation, the raw material is first added to the inside of the sealing cylinder 11 through the feed pipe 8 and the feed hopper 7. Then, the heating ring 18 is activated to heat the sealing cylinder 11, thereby melting the raw material inside the sealing cylinder 11. At the same time, the first motor 5 is activated, which drives the stirring rod 15 to rotate, agitating the raw material and making the melting more uniform. After heating is completed, the control valve 24 is opened to allow the raw material to be discharged through the discharge pipe 23. Then, the second motor 12 is activated, which drives the worm gear 10 to rotate, which in turn drives the worm wheel 14 to rotate, thereby allowing the threaded tube 21 to rotate. The threaded tube 21 controls the threaded rod 6 to move downward, and the threaded rod 6 pushes the push ring 17, which in turn pushes the scraper ring 22 to push the raw material remaining inside the sealing cylinder 11 downward, causing the raw material to flow downward and be discharged from the device, thereby effectively reducing the amount of raw material remaining.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
