Description

Technical Field

[0001] This utility model relates to the field of PUR processing technology, and in particular to a high-efficiency filling device for PUR processing that prevents adhesive from solidifying. Background Technology

[0002] PUR products are familiar to us and are mainly divided into two categories: foamed products and non-foamed products. Foamed products include soft, rigid, and semi-rigid PUR foam plastics; non-foamed products include coatings, adhesives, synthetic leather, elastomers, and elastic fibers. PUR materials have excellent performance, wide applications, and many types of products, among which PUR foam plastics are the most widely used.

[0003] Several problems exist in the processing of PUR adhesive. For example, after processing, PUR adhesive needs to be filled for subsequent transportation. During filling, PUR adhesive is prone to solidification, forming hard solid particles or lumps that can clog the filling equipment's feed pipes, metering pumps, nozzles, or valves. This necessitates machine shutdown, disassembly, and cleaning, thus affecting filling speed and quality. To address these issues, a high-efficiency filling device for PUR adhesive processing that prevents solidification is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency filling device for PUR processing that prevents adhesive from solidifying, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] Preferably, a feed pipe is fixedly installed on the top of the storage box, and a dust cover is threaded onto the surface of the feed pipe.

[0012] Preferably, both the left mounting housing and the gasket have mounting grooves for mounting the gasket on their opposing surfaces, and both the right mounting housing and the left mounting housing are overlapped with the sealing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-efficiency filling equipment for PUR processing that prevents glue from solidifying uses a heated water flow conveying component in conjunction with an inlet and outlet pipe to deliver hot water to the interlayer to add glue to the storage tank. At the same time, the heating component heats the residual glue in the outlet pipe, thereby preventing the glue from solidifying and avoiding the formation of hard solid particles or lumps after PUR glue solidifies, which could block the feed pipe, metering pump, and nozzle of the filling equipment. This also avoids the need to stop the machine for disassembly and cleaning due to blockage, which would affect the filling speed. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Example: Refer to Figure 1-5A high-efficiency filling device for PUR processing to prevent glue from solidifying includes a mounting frame 1, a storage box 2 fixedly mounted on the top of the mounting frame 1, a double-layered structure 6 inside the storage box 2, a stirring assembly on the surface of the storage box 2, a heated water conveying assembly on the top of the mounting frame 1, an upper conveying pipe 16 and an upper drain pipe 11 connected to the heating water conveying assembly on the mounting frame 1, the upper conveying pipe 16 and the upper drain pipe 11 respectively fixedly mounted on the left and right sides of the storage box 2, a discharge pipe 18 fixedly mounted on the bottom of the mounting frame 1, a heating assembly on the surface of the discharge pipe 18, and a metering pump 19 fixedly mounted on the top of the mounting frame 1, the inlet end of the metering pump 19 being connected to the discharge pipe 19. The metering pump 19 is connected to the discharge end of the metering pump 19, which is fixedly equipped with a filling head 20. The heated water conveying assembly includes a heating box 7 and a conveying pump 13 fixedly installed on the top of the mounting frame 1. A heating plate 8 is installed inside the heating box 7. A return pipe 9 is fixedly installed on the right side of the heating plate 8. A confluence pipe 10 is fixedly installed at the liquid inlet end of the return pipe 9. An upper drain pipe 11 is fixedly installed on the left side of the confluence pipe 10. A connecting pipe 14 is fixedly installed at the liquid inlet end of the conveying pump 13. The liquid inlet end of the connecting pipe 14 passes through the heating box 7 and extends into the interior of the heating box 7. An installation pipe 15 is fixedly installed at the liquid outlet end of the conveying pump 13. An upper conveying pipe 16 is fixedly installed on the right side of the installation pipe 15. The heating assembly includes a limiting circular plate 21 and a sealing ring 27 fixedly installed on the surface of the discharge pipe 18. A sealing ring 27 is fixedly installed on the surface of the discharge pipe 18. A right mounting shell 22 and a left mounting shell 23 are overlapped between the opposing faces of the limiting circular plates 21. A sealing gasket 24 is overlapped inside the left mounting shell 23, overlapping with the right mounting shell 22. A fixing post 25 is fixedly installed on the left side of the right mounting shell 22, overlapping with the left mounting shell 23. A washer nut 26 is threaded on the surface of the fixing post 25. A lower conveying pipe 17 is fixedly installed on the left side of the left mounting shell 23, fixedly installed on the right side of the mounting pipe 15. A lower drain pipe 12 is fixedly installed on the right side of the right mounting shell 22, fixedly installed on the left side of the confluence pipe 10. Water flows into the heating box 7 through the heating plate 8. The water is added by pump 13, which draws heated water from the heating chamber 7 through connecting pipe 14 into the mounting pipe 15. After being split through the mounting pipe 15, the water enters the upper conveying pipe 16 and the lower conveying pipe 17. The heated water then flows through the upper and lower conveying pipes 16 and 17 respectively into the interlayer 6 and between the right mounting housing 22 and the left mounting housing 23. This allows the heat from the added water to be transferred to the adhesive inside the storage tank 2. It also heats the adhesive inside the discharge pipe 18. The heated water then flows back through the lower drain pipe 12 and upper drain pipe 11 to the confluence pipe 10, and then back through the return pipe 9 to the heating chamber 7 for reheating. This prevents the adhesive from solidifying and avoids the formation of hard solid particles or lumps after the PUR adhesive has solidified.This avoids the problem of clogging the filling equipment's feed pipes, metering pumps, and nozzles, thus preventing the need for machine shutdown and cleaning that would affect filling speed.

[0022] Specifically, the mixing assembly includes a mixing motor 3 fixedly installed on the top of the storage box 2. A mixing shaft 4 is fixedly installed at the output end of the mixing motor 3, and a mixing paddle 5 is fixedly installed on the surface of the mixing shaft 4. Both the mixing shaft 4 and the mixing paddle 5 are located inside the storage box 2. The mixing motor 3 drives the mixing paddle 5 through the mixing shaft 4 to mix the glue, so that the glue in the storage box 2 is heated evenly, avoiding the situation where the glue in the storage box 2 is not heated evenly, thereby avoiding the situation where the glue solidifies in some places.

[0023] Specifically, a temperature sensor and a water supply pipe are fixedly installed on the top of the heating box 7. The detection end of the temperature sensor passes through the heating box 7 and extends into the interior of the heating box 7. A sealing cap is provided on the threaded surface of the water supply pipe. The temperature sensor facilitates the detection of the water temperature inside the heating box 7, avoiding excessively high or low temperatures. The water supply pipe facilitates the replenishment of water into the heating box 7.

[0024] Specifically, a feed pipe is fixedly installed on the top of the storage box 2, and a dust cover is threaded on the surface of the feed pipe. The feed pipe facilitates the addition of glue into the storage box 2, and the dust cover helps prevent dust from entering the storage box 2.

[0025] Specifically, the left mounting housing 23 and the sealing gasket 24 are both provided with mounting grooves for mounting the sealing gasket 24. The right mounting housing 22 and the left mounting housing 23 are both overlapped with the sealing ring 27. The mounting grooves facilitate the installation of the sealing gasket 24, making the installation position of the sealing ring 27 accurate.

[0026] In use: Water is added to the heating box 7 via the heating plate 8. The delivery pump 13 draws the heated water from the heating box 7 into the installation pipe 15 through the connecting pipe 14. After being split by the installation pipe 15, the water enters the upper delivery pipe 16 and the lower delivery pipe 17. The heated water enters the interlayer 6 through the upper delivery pipe 16, allowing the heat from the added water to be transferred to the glue inside the storage box 2. The water then flows back to the confluence pipe 10 through the upper drain pipe 11, and then back to the heating box 7 through the return pipe 9 for reheating. Simultaneously, the water flows through the lower delivery pipe... The feed pipe 17 enters between the right mounting housing 22 and the left mounting housing 23 to heat the discharge pipe 18. The heat is transferred to the glue inside the discharge pipe 18, and then flows back to the confluence pipe 10 through the drain pipe 12. It then flows back to the heating box 7 through the return pipe 9 for reheating. When heating the glue inside the storage box 2, because there is too much glue in the storage box 2, the stirring motor 3 drives the stirring shaft 4 to rotate, so that the stirring shaft 4 drives the stirring paddle 5 to stir the glue, so that the glue in the storage box 2 is heated evenly.

[0027] The installation process involves inserting the sealing gasket 24 into the mounting groove of the right mounting housing 22, placing the right mounting housing 22 between the limiting circular plates 21 so that the right mounting housing 22 contacts the sealing ring 27, and then placing the left mounting housing 23 between the limiting circular plates 21 so that the fixing post 25 is inserted into the left mounting housing 23 and the sealing gasket 24 is inserted into the mounting groove of the left mounting housing 23. The gasket nut 26 is then tightened onto the surface of the fixing post 25, so that the right mounting housing 22 and the left mounting housing 23 are in close contact and that the right mounting housing 22 and the left mounting housing 23 compress the sealing ring 27, thus completing the installation process of the right mounting housing 22 and the left mounting housing 23.
