Description

Technical Field

[0001] This utility model relates to the field of PVC weld sealant production technology, specifically a high-speed dispersion device for PVC weld sealant production. Background Technology

[0002] PVC weld sealant is a paste-like sealant composed of polyvinyl chloride paste resin, plasticizer, filler, pigment, etc. It is polymerized by emulsion or micro-suspension methods and has excellent thixotropic properties and adhesive strength. After heating and plasticizing, it can form an elastomer, exhibiting excellent wear resistance, flexural resistance, and chemical resistance. The dispersion device plays a core role in the production of PVC weld sealant. It achieves efficient shearing and uniform mixing of materials through a multi-stage stirring structure, and precisely regulates the reaction temperature with a jacketed temperature control system to ensure that the PVC resin and filler are fully dispersed and there is no local overheating degradation.

[0003] Chinese Patent Publication No. CN217140092U discloses a sealant dispersion device, including a dispersion tank and a central dispersion shaft disposed within the dispersion tank. The central dispersion shaft is connected to at least three vertically arranged posts near the inner wall of the dispersion tank. Each post is equipped with a scraper, and the height of the scraper on each post decreases sequentially from the highest point of material dispersion to the bottom of the dispersion tank. The central dispersion shaft has at least two layers of dispersion plates. The dispersion tank is equipped with a driving device connected to the central dispersion shaft. The sealant dispersion device of this invention has the advantages of thoroughly scraping the side walls of the dispersion tank and achieving good sealant uniformity.

[0004] Because PVC weld sealant has a certain degree of viscosity and poor flowability, it easily sticks to the inner wall of the dispersion tank. Existing dispersion devices use scrapers to scrape the PVC weld sealant off, but even so, the PVC weld sealant at the edges is difficult to flow to the middle stage of the dispersion device to improve dispersion. Therefore, we propose a high-speed dispersion device for the production of PVC weld sealant. Utility Model Content

[0021] Please see Figure 1-3A high-speed dispersion device for producing PVC weld sealant includes a base 1, a dispersion tank 9 mounted above the base 1, a tank cover 4 mounted above the dispersion tank 9, a connecting pipe 8 mounted above the tank cover 4, a lifting plate 6 mounted above the connecting pipe 8, a dispersion motor 7 mounted above the lifting plate 6, a transmission rod 10 mounted at the output end of the dispersion motor 7, a second transmission gear 15 and a first gear disc 16 mounted on the outer surface of the transmission rod 10, an installation groove 12 formed inside the tank cover 4, and a connecting bearing 21 mounted on the inner wall of the installation groove 12. The rotating disk 19 is installed inside the rotating disk 19. The lifting cylinders 3 are fixedly installed on both sides below the rotating disk 19. The spiral auger 22 is movably installed inside the lifting cylinder 3. The second gear 20 is installed above the spiral auger 22. The chain 17 is connected to the right side of the second gear 20. The lifting cylinder 3 has a scraping port 23 on the side near the dispersion tank 9. The internal gear 13 is installed above the rotating disk 19. Three first transmission gears 14 are movably installed at the top of the mounting groove 12. The scraper 11 is fixedly installed below the lifting cylinder 3. The rotating disk 19 has an mounting cavity 18 inside.

[0022] In this implementation scheme: by setting a material lifting cylinder 3 inside the dispersion tank 9, the sealant on the edge of the dispersion tank 9 is scraped off and transported to the middle of the dispersion tank 9 for dispersion and stirring, so that the sealant is stirred more evenly.

[0023] Furthermore:

[0024] In an optional embodiment, the top of the auger 22 extends through the inner wall of the mounting cavity 18, and the auger 22 achieves chain drive with the transmission rod 10 through the second toothed disc 20, the chain 17 and the first toothed disc 16.

[0025] In this implementation scheme: when the transmission rod 10 rotates, it drives the spiral auger 22 to rotate and cooperate with the lifting cylinder 3 to transport the sealant raw material at the edge of the dispersion tank 9 to the middle of the dispersion tank 9 for dispersion.

[0026] Furthermore:

[0027] In an optional embodiment, the rotating disk 19 is movably connected to the mounting groove 12 via the connecting bearing 21, the internal gear 13 is meshed with the first transmission gear 14, and the first transmission gear 14 is meshed with the second transmission gear 15.

[0028] In this implementation scheme: when the transmission rod 10 rotates, it drives the rotating disk 19 to rotate, which in turn drives the lifting cylinder 3 to move along the edge of the dispersion tank 9, conveying the sealant raw material at the edge of the dispersion tank 9 to the middle of the dispersion tank 9 for dispersion.

[0029] Furthermore:

[0030] In an optional embodiment, the scraper nozzle 23 is fitted to the inner wall of the dispersion tank 9, and the lifting cylinder 3 moves inside the dispersion tank 9 via the rotating disk 19.

[0031] In this implementation scheme: when the lifting cylinder 3 moves, it can scrape down the sealant material on the edge of the dispersion tank 9 and transport it to the middle of the dispersion tank 9 for dispersion, while driving the scraper 11 to scrape down the sealant material at the bottom of the dispersion tank 9.

[0032] Furthermore:

[0033] In an optional embodiment, the dispersion tank 9 is further provided with:

[0034] Electric push rod 5 is installed on both sides of dispersion tank 9. The output end of electric push rod 5 is fixedly connected to lifting plate 6, and the bottom of electric push rod 5 is fixedly connected to base 1.

[0035] In this implementation plan: when the electric push rod 5 is working, it can control the opening and closing between the dispersion tank 9 and the tank cover 4.

[0036] Furthermore:

[0037] In an optional embodiment, the transmission rod 10 is further provided with:

[0038] The stirring rod 2 is installed at the bottom of the transmission rod 10.

[0039] In this implementation scheme: when the transmission rod 10 rotates, it drives the stirring rod 2 to rotate and stir and disperse the sealant raw materials.

[0040] Working principle: When using this high-speed dispersion device for PVC weld sealant production, the controller first controls the electric push rod 5 to move the lifting plate 6 upward a certain distance, which in turn drives the tank cover 4 upward through the connecting pipe 8 to open the dispersion tank 9. Then, the PVC weld sealant raw material is added into the dispersion tank 9, and the tank cover 4 is closed. Next, the controller controls the dispersion motor 7 to work, which drives the transmission rod 10 and the stirring rod 2 below it to rotate and disperse the PVC weld sealant raw material. Then, the rotating transmission rod 10 drives the rotating disk 19 through the second transmission gear 15, the first transmission gear 14, and the internal gear 13, which in turn drives the rotating disk 19 through the connecting bearing 21 in the mounting groove 12. The internal rotation is relatively slow, which in turn drives the lifting cylinder 3 and the scraper 11 below it to rotate inside the dispersion tank 9. During the rotation of the lifting cylinder 3, the scraper port 23 scrapes off the PVC weld sealant material adhering to the inner wall of the dispersion tank 9. At the same time, the scraper 11 scrapes off the PVC weld sealant material at the bottom of the dispersion tank 9. Then, the rotating transmission rod 10 drives the spiral auger 22 to rotate through the first toothed disc 16, chain 17 and second toothed disc 20. It works in conjunction with the lifting cylinder 3 to transport the PVC weld sealant material from the edge of the dispersion tank 9 to the middle of the dispersion tank 9, so that the PVC weld sealant material is dispersed more evenly. This is the working principle of the high-speed dispersion device for PVC weld sealant production.
