Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to a cooling device for improving the quality of the inner wall of UPVC pipes. Background Technology

[0002] Cooling after pipe extrusion is crucial. Its main purpose is to rapidly solidify and shape the pipe, prevent deformation or sagging at high temperatures, and ensure dimensional stability. By controlling the cooling rate, the crystallinity and mechanical properties of the material can be optimized, internal stress can be reduced, and later cracking can be avoided. In addition, cooling can improve production efficiency, harden the pipe as quickly as possible for subsequent processing, improve surface quality, prevent roughness or oxidation defects, and ensure that the product appearance and performance meet the requirements.

[0003] Existing pipe cooling devices have significant limitations in use. Their cooling structures are usually fixed and cannot be flexibly adjusted according to the inner diameter of different pipes. This rigid structure often results in a large gap between the airflow and the inner wall of the pipe during cooling, which seriously affects the cooling efficiency. Especially when processing pipes of different specifications, the fixed air duct structure is difficult to form an effective airflow coverage, resulting in uneven cooling of the inner wall of the pipe and potential insufficient cooling in some areas. In addition, the excessive airflow gap also causes energy waste, further reducing the overall performance of the cooling system. This design defect directly leads to unsatisfactory pipe cooling effect and affects the quality of subsequent processing.

[0004] Therefore, in view of the problem that the existing pipe cooling devices are usually fixed in their cooling structure and cannot be adjusted according to the inner diameter of the pipe, and that there may be a large gap between the airflow and the inner wall of the pipe during air blowing, resulting in unsatisfactory cooling effect, a cooling device to improve the inner wall quality of UPVC pipes can be designed. Utility Model Content

[0005] To overcome the problem that existing pipe cooling devices typically have a fixed cooling structure that cannot be adjusted according to the inner diameter of the pipe, and that there may be a large gap between the airflow and the inner wall of the pipe during air blowing, resulting in unsatisfactory cooling effect.

[0006] The technical solution of this utility model is as follows: a cooling device for improving the inner wall quality of UPVC pipes, including a control cabinet; and an outer support shell. A bearing seat is installed on the top of the control cabinet, and a protective tube is fixed inside the bearing seat. A fixed plate is installed on the left end of the protective tube, and a pushing mechanism is provided on the right side of the fixed plate. A push rod is slidably connected through the right side of the fixed plate. The pushing mechanism is used to push the push rod to move left and right. Multiple equally spaced mounting slots are opened through the upper side of the push rod. Two first rotating shafts are rotatably connected inside the mounting slots, and connecting rods are sleeved on the outer side of the first rotating shafts. A second rotating shaft is inserted and rotatably connected to the connecting rod, and a positioning rod is inserted and rotatably connected to the connecting rod. A positioning sleeve is rotatably connected to the outside of the positioning rod. An outer support shell is provided on the outside of the second rotating shaft. A limit groove is opened on the outside of the outer support shell. The second rotating shaft is slidably connected to the limit groove. Two sliding grooves are opened on the left side of the fixed plate. The outer support shell is slidably connected to the sliding grooves. Multiple air blowing ports are opened on the outer support shell. The outer support shell is connected to an external air pump through a hose. When the external air pump is working, it can blow air out from the air blowing ports. A rotating mechanism is provided on the top of the control cabinet. The rotating mechanism is used to drive the outer support shell to rotate.

[0007] Preferably, by setting a pushing mechanism, the push rod can be driven to move left and right during operation. When the push rod moves to the left, it pulls the end of the connecting rod to move synchronously through the first rotating shaft. Under the limiting action of the second rotating shaft and the positioning rod, the other end of the connecting rod will pull the outer support shell closer to the positioning sleeve, thereby reducing the distance between the two outer support shells to accommodate smaller diameter pipes. The pipe is fitted on the outside of the two outer support shells. The external air pump is started. The air pipe of the external air pump passes through the hole of the protective pipe and connects to the two outer support shells. Thus, when the air pump is running, it can blow airflow from the air outlet of the outer support shell to achieve cooling. This solves the problem that the existing pipe cooling devices usually have a fixed cooling structure that cannot be adjusted according to the inner diameter of the pipe. When blowing air, there may be a large gap between the airflow and the inner wall of the pipe, resulting in unsatisfactory cooling effect.

[0008] Preferably, the actuating mechanism includes a mounting component and a telescopic component. The mounting component is used to fix the telescopic component, and the telescopic component is used to drive the push rod to move left and right.

[0009] Preferably, the mounting assembly includes a fixing rod and a mounting plate. Four fixing rods are mounted on the right side of the fixing plate in a circular arrangement, and the mounting plate is provided at the right end of the fixing rod.

[0010] Preferably, the telescopic assembly includes a cylinder, with the cylinder located on the right side of the mounting plate. The output end of the cylinder is fixedly connected to the push rod, and the cylinder is used to drive the push rod to move left and right.

[0011] Preferably, the rotating mechanism includes a drive component and a linkage component, wherein the drive component drives the protective tube to rotate in cooperation with the linkage component.

[0012] Preferably, the drive assembly includes a fixed platform, a drive motor, and a first gear column. The fixed platform is mounted on the top of the control cabinet, and the drive motor is mounted on the top of the fixed platform. The output end of the drive motor is connected to the first gear column, and the drive motor is used to drive the first gear column to rotate.

[0013] Preferably, a second toothed post is installed at the right end of the protective tube, and a belt is fitted on the outer side of the first and second toothed posts.

[0014] The beneficial effects of this utility model are:

[0015] By setting an adjustable-spacing outer support shell, this device can flexibly adjust the distance between the air blowing port and the inner wall of the pipe according to the inner diameter of different pipes, ensuring that the airflow efficiently covers the inner wall surface and significantly improves the uniformity of cooling. The air blowing port of the outer support shell blows air out in a direction that acts directly on the inner wall of the pipe, effectively reducing the pipe temperature and accelerating heat dissipation. This avoids the problem of airflow diffusion and reduced cooling efficiency caused by excessive spacing. This design not only enhances the stability of cooling quality but also adapts to various pipe diameter specifications, greatly improving production adaptability while reducing energy waste, and providing reliable cooling protection for the pipe forming process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a cooling device for improving the inner wall quality of UPVC pipes, comprising a control cabinet 1 and an outer support shell 11. A bearing seat 2 is mounted on the top of the control cabinet 1. A protective tube 3 is fixed inside the bearing seat 2. A fixed plate 4 is mounted on the left end of the protective tube 3. A pushing mechanism is provided on the right side of the fixed plate 4. A push rod 6 is slidably connected through the right side of the fixed plate 4. The pushing mechanism is used to push the push rod 6 to move left and right. Multiple equally spaced mounting slots 7 are provided through the upper side of the push rod 6. Two first rotating shafts 8 are rotatably connected inside the mounting slots 7. A connecting rod 9 is sleeved on the outer side of the first rotating shaft 8. A second rotating shaft 10 is inserted and rotatably connected to the connecting rod 9. A positioning rod 16 is inserted and rotatably connected to the connecting rod 9. A positioning sleeve 15 is rotatably connected to the outer side of the positioning rod 16. An outer support shell 11 is provided on the outer side of the second rotating shaft 10. A limiting groove 12 is provided on the outer side of the outer support shell 11. The second rotating shaft 10 is slidably connected to the limiting groove 12. Two sliding grooves 13 are provided on the left side of the fixed plate 4. The outer support shell 11 is slidably connected to the slide groove 13. Multiple air inlets are provided on the outer support shell 11. The outer support shell 11 is connected to an external air pump via a hose. When the external air pump is operating, airflow can be blown out from the air inlets. A rotating mechanism is provided on the top of the control cabinet 1. This rotating mechanism is used to drive the outer support shell 11 to rotate. A pushing mechanism is provided. During operation, the pushing mechanism drives the push rod 6 to perform a lateral reciprocating motion. When the push rod 6 moves to the left, it pulls the first end of the connecting rod 9 to move synchronously through the first rotating shaft 8. At this time, the end of the connecting rod 9 is at the... Under the dual constraint of the two rotating shafts 10 and the positioning rod 16, the outer support shell 11 will be driven to move towards the positioning sleeve 15, thereby reducing the working distance between the two outer support shells 11 to meet the processing requirements of smaller diameter pipes. After the pipe to be processed is fitted on the outside of the two outer support shells 11, the external air pump is started. The airflow delivery pipeline of the air pump passes through the through hole on the protective pipe 3 and connects to the two outer support shells 11. When the air pump is working, the compressed airflow is discharged through the air blowing hole on the surface of the outer support shell 11 to achieve the cooling effect on the workpiece.

[0024] Please see Figures 2-5 In this embodiment, the pushing mechanism includes an installation component and a telescopic component. The installation component is used to fix the telescopic component, and the telescopic component is used to drive the push rod 6 to move left and right. The installation component includes a fixed rod 51 and a mounting plate 52. Four fixed rods 51 distributed in a circle are installed on the right side of the fixed plate 4. The mounting plate 52 is provided at the right end of the fixed rod 51. The fixed rods 51 are used to position and install the mounting plate 52. The telescopic component includes a cylinder 53. The cylinder 53 is provided on the right side of the mounting plate 52. The output end of the cylinder 53 is fixedly connected to the push rod 6. The cylinder 53 is used to drive the push rod 6 to move left and right. By providing the cylinder 53, the push rod 6 can be pushed to move left and right during operation.

[0025] Please see Figures 1-3In this embodiment, the rotating mechanism includes a driving component and a linkage component. The driving component, in cooperation with the linkage component, drives the protective tube 3 to rotate. The driving component includes a fixed platform 141, a driving motor 142, and a first gear 143. The fixed platform 141 is mounted on the top of the control cabinet 1, and the driving motor 142 is mounted on the top of the fixed platform 141. The output end of the driving motor 142 is connected to the first gear 143. The driving motor 142 is used to drive the first gear 143 to rotate. By setting the driving motor 142, the first gear 143 can be driven to rotate during operation. 143 rotates, and a second toothed column 144 is installed on the right end of the protective tube 3. A belt 145 is sleeved on the outer side of the first toothed column 143 and the second toothed column 144. By setting the belt 145, the first toothed column 143 and the second toothed column 144 can be linked together, so that the first toothed column 143 can drive the second toothed column 144 to rotate synchronously when it rotates. The output end of the drive motor 142 is kept to rotate slightly in the forward and reverse directions through an external controller, so as to drive the two outer support shells 11 to rotate slightly, thereby expanding the airflow blowing range and improving the cooling effect.

[0026] When cooling is required for UPVC pipes with different inner diameters, cylinder 53 pushes push rod 6 to the left. Push rod 6 drives one end of connecting rod 9, which is connected to the first rotating shaft 8, to move. The other end of connecting rod 9, constrained by the second rotating shaft 10 and positioning rod 16, pulls the outer support shell 11 along the sliding groove 13 on the fixed plate 4 towards the positioning sleeve 15, thereby reducing the distance between the two outer support shells 11 to accommodate smaller diameter pipes. Conversely, when cylinder 53 pulls push rod 6 to the right, connecting rod 9 pushes the outer support shell 11 to slide outward, increasing the distance to accommodate larger diameter pipes. The pipe fits onto the two outer support shells 11 with the distance adjusted. After the outer side is reached, the external air pump is started, and the airflow is delivered to the inside of the outer support shell 11 through the hose and blown out from the air outlet on its surface, directly acting on the inner wall of the pipe for cooling. At the same time, the drive motor 142 is started, driving the first toothed column 143 at its output end to rotate. The first toothed column 143 drives the second toothed column 144 fixed to the right end of the protective pipe 3 to rotate through the belt 145, thereby driving the entire protective pipe 3 and the outer support shell 11 to rotate slightly in both directions, so that the airflow blown out from the air outlet can more evenly cover the inner wall of the pipe, thereby significantly improving the cooling effect. The entire operation process is controlled by the control cabinet 1.

[0027] Through the above steps, during operation, the push mechanism drives the push rod 6 to move laterally. When the push rod 6 moves to the left, it drives one end of the connecting rod 9 to move along with it through the first rotating shaft 8. The other end of the connecting rod 9, due to the constraint of the second rotating shaft 10 and the positioning rod 16, will force the outer support shell 11 to retract towards the positioning sleeve 15, thereby reducing the distance between the two outer support shells 11 to accommodate smaller diameter pipes. In use, the pipe is fitted on the outside of the two outer support shells 11. After the external air pump is started, the airflow passes through the air pipe through the hole of the protective pipe 3 and enters the interior of the outer support shell 11, and finally sprays out from the air blowing port to achieve the cooling effect on the pipe. This solves the problem that the existing pipe cooling device usually has a fixed cooling structure that cannot be adjusted according to the inner diameter of the pipe. When blowing air, there may be a large gap between the airflow and the inner wall of the pipe, resulting in an unsatisfactory cooling effect.
