Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for PVC profiles. Background Technology

[0002] Cooling devices play an indispensable role in PVC profile production. When the PVC profiles extruded at high temperatures leave the mold, their internal structure is not yet fully stable. If they are not cooled in time, the profiles will deform and shrink due to their residual heat, resulting in a decrease in dimensional accuracy, affecting product quality and subsequent use. At the same time, an appropriate cooling rate can also promote the stability of the PVC molecular structure, enhance the strength and hardness of the profiles, and improve their physical properties. In addition, cooling devices help shorten the profile production cycle, improve production efficiency, reduce energy consumption, and provide a strong guarantee for the continuous and stable production of PVC profiles, ensuring that the final products meet quality standards and satisfy market demands.

[0003] However, in existing technologies, some PVC cooling devices use a single cooling method, such as single-sided spraying or localized air cooling, which results in inconsistent cooling rates in different parts of the profile. Furthermore, the profile is prone to shifting during transport, leading to uneven contact with the cooling components, which further exacerbates the uneven cooling and affects the cooling quality. Therefore, we need a cooling device for PVC profiles. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling device for PVC profiles to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for PVC profiles, comprising a base plate, a molding machine mounted on the top of the base plate, a feeding cylinder mounted on the top of the molding machine, a conveying trough mounted on one side of the molding machine, an adjusting component mounted inside the conveying trough, a support frame fixedly connected to the top of the base plate, a cooling component mounted on the top of the support frame, a sensor mounted on the top of the cooling component, the cooling component comprising a pre-cooling chamber fixedly connected to the top of the support frame, a protective shell fixedly connected to the outer wall of the pre-cooling chamber, a cylinder mounted on the top of the pre-cooling chamber, a fixed rod fixedly connected to the push rod of the cylinder, a rack fixedly connected to the bottom of the fixed rod, a drive gear meshing with the outer wall of the rack, a driven gear meshing with the outer wall of the drive gear, an air outlet fixedly connected to one side of the driven gear, an air duct fixedly connected to the top of the air outlet, a main cooling chamber mounted on one side of the pre-cooling chamber, and a fine cooling chamber mounted on one side of the main cooling chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. The product enters the pre-cooling box through the conveyor trough. Through the blowing of cold air and the adjustment of the air outlet angle, the initial temperature is reduced to avoid stress concentration and improve the uniformity of pre-cooling. Then it enters the main cooling box, where the ring spray pipe achieves rapid and uniform cooling.

At the same time, the spacing between the uprights can be flexibly adjusted according to the size of the product. The rotating handle drives the bevel gear and the double-headed screw to rotate, which causes the sliding sleeve to drive the connecting column and the uprights to move, achieving precise guidance for products of different widths and effectively improving the adaptability and stability of the cooling process.

[0015] 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.

[0016] This utility model embodiment provides a cooling device for PVC profiles, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the system includes a base plate 1, a molding machine 2 mounted on top of the base plate 1, a feed cylinder 3 mounted on top of the molding machine 2, a conveying trough 4 on one side of the molding machine 2, an adjusting component 5 inside the conveying trough 4, a support frame 6 fixedly connected to the top of the base plate 1, a cooling component 7 mounted on top of the support frame 6, a sensor 8 mounted on top of the cooling component 7, and a pre-cooling box 701 fixedly connected to the top of the support frame 6. A protective shell 702 is fixedly connected to the outer wall of the precooling box 701. A cylinder 703 is installed on the top of the precooling box 701. A fixed rod 704 is fixedly connected to the push rod of the cylinder 703. A rack 705 is fixedly connected to the bottom of the fixed rod 704. A drive gear 706 is meshed with the outer wall of the rack 705. A driven gear 707 is meshed with the outer wall of the drive gear 706. An air outlet 708 is fixedly connected to one side of the driven gear 707. An air supply pipe 70 is fixedly connected to the top of the air outlet 708. 9. A main cooling box 710 is set on one side of the pre-cooling box 701, and a fine cooling box 711 is set on one side of the main cooling box 710. After passing through the conveying trough 4, the product enters the pre-cooling box 701 to pre-cool the surface of the profile and avoid stress concentration caused by direct sudden cooling. At this time, the cold air enters the air outlet 708 through the air duct 709 and is blown out. At the same time, the cylinder 703 is activated to drive the fixed rod 704 to move. The fixed rod 704 drives the rack 705 to move, which in turn drives the drive gear 706 to move. The drive gear 706 drives the driven gear 707 to rotate, which in turn drives the air outlet 708 to rotate, completing the angle adjustment and further improving the pre-cooling effect. After passing through the pre-cooling box 701, the product enters the main cooling box 710. The main cooling box 710 is equipped with an annular spray pipe to quickly and evenly cool the profile. Finally, the product enters the fine cooling box 711, where hot air drying is added on the basis of water mist cooling to avoid residual moisture on the surface of the profile and improve the cooling effect.

[0017] Furthermore, such as Figure 7 As shown, the cylinder 703 forms a movable structure with the rack 705 via the fixed rod 704. One side of the fixed rod 704 is fixedly connected to the push rod of the cylinder 703, and the bottom of the fixed rod 704 is fixedly connected to the top of the rack 705. This allows the fixed rod 704 to move when the cylinder 703 moves the fixed rod 704, which in turn moves the rack 705.

[0018] Furthermore, such as Figure 7As shown, the rack 705 forms a rotating structure through the drive gear 706 and the driven gear 707. The outer wall of the drive gear 706 meshes with the outer wall of the rack 705, and the outer wall of the drive gear 706 meshes with the outer wall of the driven gear 707. This allows the rack 705 to drive the drive gear 706 to rotate, which in turn causes the drive gear 706 to drive the driven gear 707 to rotate.

[0019] Furthermore, such as Figure 7 As shown, the fixed rod 704 forms a rotating structure with the drive gear 706 via the rack 705, and the top of the rack 705 is fixedly connected to the bottom of the fixed rod 704, and the outer wall of the rack 705 is meshed with the outer wall of the drive gear 706, so that when the fixed rod 704 moves the rack 705, the rack 705 drives the drive gear 706 to rotate.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjusting assembly 5 includes a conveying roller 501, which is rotatably connected inside the conveying trough 4. A driven roller 502 is rotatably connected to the inner wall of the conveying trough 4. A silicone layer 503 is provided on the outer wall of the driven roller 502, and a guide groove 504 is provided on the outer wall of the driven roller 502. A fixing plate 505 is fixedly connected inside the conveying trough 4. A fixing frame 506 is fixedly connected to the top of the fixing plate 505. A rotating handle 507 is rotatably connected inside the fixing frame 506. A first bevel gear 508 is fixedly connected to the outer wall of the rotating handle 507. A second bevel gear 509 is meshed with the outer wall of the first bevel gear 508. A double-ended screw 510 is fixedly connected to the inner wall of the second bevel gear 509. A sliding sleeve 511 is threadedly connected to the outer wall of the double-ended screw 510. A connecting column 512 is fixedly connected to the bottom of 1, and a vertical plate 513 is fixedly connected to one side of the connecting column 512. When the PVC profile is extruded and cooled, the product first enters the conveying trough 4 and moves along the guide groove 504 through the conveying roller 501 and the driven roller 502. The roller surface is covered with a high-temperature resistant silicone layer 503. The spacing of the vertical plate 513 can be adjusted according to the size of the product. By turning the handle 507, it drives the first bevel gear 508 to rotate. The first bevel gear 508 drives the second bevel gear 509 to rotate, so that the second bevel gear 509 drives the double-headed screw 510 to rotate inside the sliding sleeve 511. In turn, the sliding sleeve 511 drives the connecting column 512 to move, and the connecting column 512 drives the vertical plate 513 to move, so that it can guide products of different widths.

[0021] Furthermore, such as Figure 4As shown, the first bevel gear 508 forms a rotating structure with the second bevel gear 509 and the double-ended screw 510. The outer wall of the second bevel gear 509 meshes with the outer wall of the first bevel gear 508, and the inner wall of the second bevel gear 509 is fixedly connected to the outer wall of the double-ended screw 510. This allows the second bevel gear 509 to rotate when the first bevel gear 508 drives it, which in turn drives the double-ended screw 510 to rotate.

[0022] Furthermore, such as Figure 4 As shown, the sliding sleeve 511 forms a movable structure with the upright plate 513 through the connecting column 512, and the top of the connecting column 512 is fixedly connected to the bottom of the sliding sleeve 511, and one side of the connecting column 512 is fixedly connected to one side of the upright plate 513, so that when the sliding sleeve 511 moves the connecting column 512, the connecting column 512 moves the upright plate 513.

[0023] Working Principle: After PVC profiles are extruded and cooled, the product first enters the conveyor trough 4 and moves along the guide groove 504 via the conveyor rollers 501 and driven rollers 502. The roller surfaces are covered with a high-temperature resistant silicone layer 503. The spacing of the upright plates 513 can be adjusted according to the size of the product. By turning the handle 507, it drives the first bevel gear 508 to rotate. The first bevel gear 508 drives the second bevel gear 509 to rotate, which in turn drives the double-headed screw 510 to rotate inside the sliding sleeve 511. This causes the sliding sleeve 511 to move the connecting column 512, which in turn moves the upright plate 513, thus guiding products of different widths. After passing through the conveyor trough 4, the product enters the pre-cooling chamber 701 to cool the profile surface. Initial cooling is performed to avoid stress concentration caused by direct and sudden cooling. At this time, cold air enters the air outlet 708 through the air duct 709 and is blown out. At the same time, the cylinder 703 is activated to move the fixed rod 704. The fixed rod 704 moves the rack 705, which in turn moves the drive gear 706. The drive gear 706 then rotates the driven gear 707, which in turn rotates the air outlet 708, completing the angle adjustment and further improving the pre-cooling effect. After passing through the pre-cooling box 701, the material enters the main cooling box 710. The main cooling box 710 is equipped with an annular spray pipe to quickly and evenly cool the profile. Finally, the material enters the fine cooling box 711, where hot air drying is added to the water mist cooling to avoid residual moisture on the profile surface and improve the cooling effect.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
