Description

Technical Field

[0001] This utility model relates to the field of PUR adhesive production technology, and in particular to a heating device for PUR adhesive production. Background Technology

[0002] PUR adhesive is mainly composed of isocyanate-terminated polyurethane prepolymer. It becomes fluid when heated, develops initial tack strength when cooled, and undergoes a chemical cross-linking reaction upon contact with air or moisture in the substrate, eventually curing to form a high-strength adhesive layer.

[0003] In the production and processing of adhesives, the heating and stirring process is a crucial step. Typically, a specialized heating device is needed to heat the adhesive raw materials, along with a stirring device to ensure thorough and uniform mixing. However, in practice, several challenging problems often arise. The most prominent is that the adhesive tends to adhere to the inner wall of the heating chamber during heating and stirring. After each production run, a significant amount of manpower and time is required to manually clean the adhesive residue from the inner wall of the heating chamber, increasing the workload of the operators. Therefore, this invention provides a heating device for PUR adhesive production. Summary of the Invention

A moving assembly is located on the top of the heating chamber, and a connecting rod is connected to the heating chamber via the moving assembly. The connecting rod is slidably connected to the heating chamber. A diverter pipe is fixedly installed at the bottom of the connecting rod, and nozzles are fixedly installed on both the outer and inner walls of the diverter pipe. An inlet pipe is fixedly installed at the top of the diverter pipe and is slidably connected to the heating chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This heating device for PUR glue production connects the inlet pipe to an external high-pressure water pipe. During the heating process of PUR glue, heating is achieved from the outside through heating wires and from the inside through heating rods, making the heat distribution inside the glue more uniform and thus completing the heating of PUR glue faster. After heating the PUR glue, the drive assembly rotates the shaft, causing the scraper to rotate, which can scrape off the PUR glue adhering to the heating chamber. The external high-pressure water pipe delivers high-pressure water to the inlet pipe, then through the diversion pipe, and finally sprays it out from the nozzle. The high-pressure water sprayed from the nozzle washes the inner wall of the heating chamber, the scraper, the heating rod, and the stirring plate. At the same time, the moving assembly allows the moving block to move up and down, adjusting the height of the connecting rod, diversion pipe, nozzle, and inlet pipe to perform washing at different heights, realizing the automation of the cleaning process, significantly improving the cleaning speed, and ensuring that every corner inside the heating chamber is thoroughly cleaned.

[0020] Reference Figure 1-4A heating device for PUR adhesive production includes a heating chamber 1, a heating wire 3 fixedly installed inside the heating chamber 1, a drive assembly on the top of the heating chamber 1, a rotating shaft 8 installed inside the heating chamber 1 via the drive assembly, the rotating shaft 8 being rotatably connected to the heating chamber 1, a stirring plate 9 fixedly installed on the surface of the rotating shaft 8, a heating rod 10 fixedly installed on the surface of the rotating shaft 8, and a scraper 11 fixedly installed on the surface of the rotating shaft 8. Multiple scrapers 11 are provided, and all scrapers 11 overlap with the inner wall of the heating chamber 1. The top of the heating chamber 1 is equipped with... The heating chamber 1 is equipped with a movable component. A connecting rod 19 is mounted on the top of the heating chamber 1 via the movable component. The connecting rod 19 is slidably connected to the heating chamber 1. A diversion pipe 20 is fixedly installed at the bottom of the connecting rod 19. Spray nozzles 21 are fixedly installed on both the outer and inner walls of the diversion pipe 20. An inlet pipe 22 is fixedly installed at the top of the diversion pipe 20 and is slidably connected to the heating chamber 1. Support legs 24 are fixedly installed at the bottom of the heating chamber 1. There are multiple support legs 24. This heating device for PUR glue production connects the inlet pipe 22 to an external high-pressure... The water pipes are connected, and during the heating of the PUR adhesive, the heating wire 3 heats from the outside, while the heating rod 10 heats from the inside, making the heat distribution inside the adhesive more uniform, thus completing the heating of the PUR adhesive faster. At the same time, after the PUR adhesive is heated, the drive component makes the rotating shaft 8 rotate, which makes the scraper 11 rotate, and can scrape off the PUR adhesive adhering to the heating box 1. With the help of the external high-pressure water pipe, high-pressure water is delivered to the liquid inlet pipe 22, then to the diversion pipe 20, and then sprayed out from the nozzle 21. The high-pressure water sprayed from the nozzle 21 washes the inner wall of the heating box 1, the scraper 11, the heating rod 10, and the stirring plate 9. At the same time, the moving component can make the moving block 18 move up and down, which can adjust the height of the connecting rod 19, the diversion pipe 20, the nozzle 21, and the liquid inlet pipe 22 to perform rinsing at different heights, realizing the automation of the cleaning process, significantly improving the cleaning speed, and ensuring that every corner inside the heating box 1 is thoroughly cleaned.

[0021] Specifically, a feed pipe 2 is fixedly installed on the top of the heating box 1. A threaded cap is threadedly connected to the top of the feed pipe 2. The liquid inlet pipe 22 is connected to an external high-pressure water pipe. Opening the threaded cap on the feed pipe 2 facilitates the addition of PUR glue to the heating box 1 from the feed pipe 2. A discharge pipe 23 is fixedly installed at the bottom of the heating box 1. A control valve is installed on the discharge pipe 23. Opening the control valve on the discharge pipe 23 facilitates the discharge of PUR glue from the discharge pipe 23.

[0022] Specifically, the drive assembly includes a mounting bracket 4 located on the top of the heating box 1. A drive motor 5 is fixedly installed inside the mounting bracket 4. A first gear 6 is fixedly installed at the output end of the drive motor 5. A second gear 7 is meshed on the surface of the first gear 6. The second gear 7 is fixedly connected to the rotating shaft 8. The drive motor 5 causes the first gear 6 to rotate, which in turn causes the second gear 7 to rotate, thus causing the rotating shaft 8 to rotate, thereby providing driving force for the rotation of the rotating shaft 8.

[0023] Specifically, the moving assembly includes a frame 12 mounted on top of the heating chamber 1. A support plate 13 is fixedly mounted on the opposing surface of the frame 12. A dual-axis motor 14 is fixedly mounted on the top of the support plate 13. A first bevel gear 15 is fixedly mounted on the output end of the dual-axis motor 14. A second bevel gear 16 is meshed on the surface of the first bevel gear 15. A screw 17 is fixedly mounted inside the second bevel gear 16. The screw 17 is rotatably connected to the frame 12. A moving block 18 is threadedly connected to the surface of the screw 17. The moving block 18 is fixedly connected to the connecting rod 19 and slidably connected to the frame 12. The dual-axis motor 14 causes the first bevel gear 15 to rotate, which in turn causes the second bevel gear 16 to rotate, which in turn causes the screw 17 to rotate. This causes the moving block 18 to move up and down, which in turn causes the connecting rod 19 to move up and down, which in turn causes the diverter pipe 20, nozzle 21, and inlet pipe 22 to move up and down, thereby performing rinsing at different heights and achieving all-round rinsing.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0025] In use: Connect the inlet pipe 22 to the external high-pressure water pipe, open the threaded cap on the inlet pipe 2, and add PUR adhesive into the heating chamber 1 through the inlet pipe 2. Then, it is heated by the heating wire 3. Simultaneously, the drive motor 5 rotates the first gear 6, which in turn rotates the second gear 7, causing the rotating shaft 8 to rotate and the stirring plate 9 to rotate, thus stirring the PUR adhesive. The rotation of the rotating shaft 8 drives the heating rod 10 to rotate, heating the PUR adhesive from within. Simultaneously, the rotation of the rotating shaft 8 also drives the scraper 11 to rotate, scraping off the PUR adhesive adhering to the heating chamber 1. After heating is complete, open the outlet... The control valve on the feed pipe 23 allows PUR glue to be discharged from the discharge pipe 23. Then, high-pressure water is delivered to the inlet pipe 22 through an external high-pressure water pipe, then into the diversion pipe 20, and finally sprayed out from the nozzle 21. The high-pressure water sprayed from the nozzle 21 washes the inner wall of the heating box 1, the scraper 11, the heating rod 10, and the stirring plate 9. At the same time, the dual-shaft motor 14 rotates the first bevel gear 15, the second bevel gear 16, and the screw 17, causing the moving block 18 to move up and down, the connecting rod 19 to move up and down, and the diversion pipe 20, the nozzle 21, and the inlet pipe 22 to move up and down, thereby washing at different heights.
