Description
Technical Field
[0001] This utility model relates to the field of waterproof membrane processing technology, and more specifically, to a cooling and shaping device for waterproof membrane production. Background Technology
[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. It is a flexible building material that can be rolled up to prevent leakage. As a leak-proof connection between the foundation and the building, it is the first line of defense for waterproofing the entire project and plays a vital role. Waterproof membrane is made of a base fabric with asphalt attached and rolled up. During production, the membrane needs to be cooled and shaped.
[0003] A search revealed that patent application CN202223333154.1 discloses a waterproof membrane cooling device, comprising a housing, a conveyor belt, and a waterproof membrane body. The conveyor belt is located inside the housing, and the waterproof membrane body is located on top of the conveyor belt. A water pump is fixedly installed on the top inside the housing. An inlet pipe is fixedly installed at the inlet end of the water pump, and an outlet pipe is fixedly installed at the outlet end of the water pump. One end of the outlet pipe is closed. Several branch pipes are fixedly installed at the bottom of both the inlet and outlet pipes. An installation slot is fixedly installed on the top inside the housing, next to the water pump. This invention cools the waterproof membrane body by pumping water in. A spring causes the bottom of a scraper to abut against the top of the waterproof membrane, and the relative movement between the two scrapers allows residual water on the waterproof membrane body to be scraped off. However, it still has the following drawbacks: (1) In the existing technology, only one side of the waterproof membrane can be sprayed and cooled, resulting in poor cooling and shaping effect. At the same time, the sprayed cooling water is inconvenient to collect and discharge, and the scraper is inconvenient to replace if it is damaged during use. In existing technologies, waterproof membranes spend a relatively short time passing through the air outlet, resulting in poor air cooling and drying effects.
[0004] Therefore, we have made improvements to this by proposing a cooling and shaping device for the production of waterproof membranes. Utility Model Content

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a cooling and shaping device for waterproof membrane production, including a base plate 1. Two uprights 2 are symmetrically and fixedly connected to the left end of the upper surface of the base plate 1. A first guide roller 3 is rotatably connected between the two uprights 2. A water receiving tank 4 is located on the right side of the uprights 2 and is fixedly connected to the base plate 1. A second guide roller 5 is rotatably connected to the left end of the water receiving tank 4. A third guide roller 6 is located on the right side of the second guide roller 5 and is rotatably connected to the water receiving tank 4. Two branch pipes 7 are symmetrically and fixedly connected to the rear end of the water receiving tank 4. Each branch pipe 7 has a spray pipe 8 fixedly connected to its output end. A set of spray nozzles 9 are evenly fixedly connected to each spray pipe 8. A water supply pipe 10 is fixedly connected between two branch pipes 7. Two upright plates 11 are symmetrically and fixedly connected to the upper surface of the water tank 4. A fourth guide roller 12 is rotatably connected between the two upright plates 11. A scraping mechanism 13 is provided between the two upright plates 11. Two mounting frames 14 are symmetrically and fixedly connected to the right end of the upper surface of the base plate 1. A set of fifth guide rollers 15 are evenly and rotatably connected between the top ends of the two mounting frames 14. A set of sixth guide rollers 16, which cooperate with the fifth guide roller 15, are evenly rotatably connected between the bottom ends of the frame 14. A cooling mechanism 17 is provided on the rear mounting frame 14. The first guide roller 3 is used to initially guide the waterproof membrane into the equipment, so that the membrane can smoothly enter the subsequent processing stage. The second guide roller 5 and the third guide roller 6 guide the movement path of the membrane in the water receiving tank 4, ensuring that the membrane maintains a stable running state during the cooling process, which facilitates spray cooling and shaping of both sides of the waterproof membrane. The fourth guide roller 12 is used to change the movement direction of the membrane. This allows the roll material to smoothly transition from the water receiving tank 4 area to the subsequent processing section. The fifth guide roller 15 and the sixth guide roller 16 form multiple sets of guide roller combinations to guide the cooled roll material, increase the contact time between the waterproof roll material and the wind, and improve the air cooling effect. When the water supply pipe 10 supplies water, the water enters the spray pipe 8 through the branch pipe 7 and is then sprayed out by the nozzle 9 to spray and cool both sides of the waterproof roll material, so that the roll material cools down quickly. The water receiving tank 4 is used to collect the water flowing down after being sprayed by the nozzle 9, realize water recycling, and avoid water waste.
[0018] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the wiping mechanism 13 further includes connecting ears 1301 respectively fixed to the inner sidewall of the upright plate 11. A first threaded post 1302 is inserted into the connecting ear 1301. A first horizontal plate 1303 is fixedly connected between two adjacent first threaded posts 1302. A first rubber scraper 1304 is fixedly connected to the first horizontal plate 1303. A connecting plate 1305 is provided on the outer side of each connecting ear 1301. The connecting plate 1305 is fixedly connected to the upright plate 11. A second threaded post 1306 is inserted into the connecting plate 1305. A second horizontal plate 1307 is fixedly connected between the two second threaded posts 1306. A second rubber scraper 1308 is fixedly connected to the second horizontal plate 1307. Nuts 1309 are threadedly connected to both the first threaded post 1302 and the second threaded post 1306. The first rubber scraper 1304 and the second rubber scraper 1308 are in close contact with the surface of the waterproof membrane to scrape off the residual moisture on the membrane and improve the dryness of the membrane. The first rubber scraper 1304 and the second rubber scraper 1308 can be easily replaced through the first threaded post 1302, the second threaded post 1306 and the nut 1309.
[0019] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the air-cooling mechanism 17 further includes an assembly plate 1701 fixed to the mounting frame 14. Two bearings 1702 are symmetrically and fixedly connected to the assembly plate 1701. A rotating shaft 1703 is fixedly connected to the inner sidewall of the inner ring of each bearing 1702. The inner end of the rotating shaft 1703 passes through the assembly plate 1701 and is fixedly connected to a fan blade 1704. A driven bevel gear 1705 is fixedly connected to the outer end of the rotating shaft 1703. Two fixing plates 1706 are symmetrically and fixedly connected to the assembly plate 1701. A transmission shaft 1707 is rotatably connected between the two fixing plates 1706. Two driving bevel gears 1708 are fixedly connected to the shaft 1707 and are respectively meshed with the driven bevel gear 1705. A motor 1709 is fixedly connected to one of the fixed plates 1706. The driving end of the motor 1709 is fixedly connected to the shaft end of the transmission shaft 1707. The motor 1709 drives the transmission shaft 1707 to rotate. The rotation of the transmission shaft 1707 drives the driving bevel gear 1708 to rotate. The rotation of the driving bevel gear 1708 drives the driven bevel gear 1705 to rotate. This causes the rotating shaft 1703 to drive the fan blade 1704 to rotate, generating wind power to further cool and dry the waterproof membrane after the water scraping treatment, and accelerate the shaping of the membrane.
[0020] like Figure 1 and Figure 6As shown, in a preferred embodiment, based on the above method, a drain pipe 18 communicating with the water tank 4 is fixedly connected to the side wall, and a control valve is installed at the outer end of the drain pipe 18; this facilitates the discharge and treatment of water in the water tank 4.
[0021] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, a frame 19 is fixedly connected to the lower end face of the base plate 1, and support feet are fixedly connected to the four corners of the lower end face of the frame 19; providing stable support for the entire equipment and ensuring the stability of the equipment during operation.
[0022] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, the number of fifth guide rollers 15 is five and the number of sixth guide rollers 16 is four; this facilitates the guidance of the waterproof membrane, increases the contact time between the waterproof membrane and the wind, and improves the air cooling effect.
[0023] Specifically, when using this cooling and shaping equipment for waterproof membrane production: the waterproof membrane is sequentially introduced between the first guide roller 3, the second guide roller 5, the third guide roller 6, the fourth guide roller 12, the fifth guide roller 15, and the sixth guide roller 16. An external water supply device supplies water to the water supply pipe 10, and the water enters the spray pipe 8 through the branch pipe 7, and is then sprayed out by the nozzle 9 to spray and cool both sides of the waterproof membrane. The water sprayed to cool the membrane is collected in the water receiving tank 4, and the first rubber scraper 1304 and the second rubber scraper 1308 are in close contact with the surface of the waterproof membrane. The water remaining on the roll material is scraped off, and the dripping water is collected in the water collection tank 4. The water-scraped waterproof roll material is driven between the fifth guide roller 15 and the sixth guide roller 16. The motor 1709 drives the transmission shaft 1707 to rotate. The rotation of the transmission shaft 1707 drives the active bevel gear 1708 to rotate. The rotation of the active bevel gear 1708 drives the driven bevel gear 1705 to rotate, which in turn causes the rotating shaft 1703 to drive the fan blade 1704 to rotate, generating wind power to further cool and dry the waterproof roll material after the water scraping treatment, accelerating the shaping of the roll material.
[0024] All technical features in this embodiment can be freely combined according to actual needs.
[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
