Description

Technical Field

[0001] This utility model relates to the field of silicone rubber wire processing technology, specifically to a silicone rubber wire cooling device with a cut-off structure. Background Technology

[0002] During the production of silicone rubber wires, the wires are at a high temperature after vulcanization and need to be cooled before they can enter the subsequent winding process.

[0003] Existing cooling equipment mostly uses a single air cooling or water cooling method, which has limited cooling efficiency. Furthermore, the cooling and cutting processes are separated, resulting in complex production line layout and low efficiency. Therefore, a silicone rubber wire cooling device with a cutting structure is proposed. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a silicone rubber wire cooling device with a cut-off structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is a silicone rubber wire cooling device with a cutting structure, including a cooling tube assembly and a cutting mechanism set at the discharge end of the cooling tube assembly. The cooling tube assembly includes an outer tube and an inner tube. The inner tube is inserted at the center of the outer tube. The two ends of the inner tube are welded and fixed to the outer tube, and a hollow cavity is formed between the outer tube and the inner tube. Heat exchange fins are welded and connected to the hollow cavity and located on the outer circumferential surface of the inner tube. The heat exchange fins do not contact the outer tube. An air inlet connector and an air outlet connector are welded to one side of the feed end and the other side of the discharge end of the outer tube, respectively. The air outlet end of the air inlet connector and the air inlet end of the air outlet connector are both connected to the inner tube, and the outer periphery of the air outlet end of the air inlet connector and the outer periphery of the air inlet end of the air outlet connector are both welded and fixed to the inner tube. The top of the feed end and the bottom of the discharge end of the outer tube are respectively welded to a water inlet connector and a drain connector, and the drain end of the water inlet connector and the water inlet end of the drain connector are connected to the hollow cavity.

[0006] By adopting the above technical solution, a cooling mechanism is provided for the processing of silicone rubber wires through a component consisting of a cooling pipe assembly and a cutting mechanism. This mechanism cools the silicone rubber wires coming off the vulcanization process, allowing them to cool down quickly so that they can enter the subsequent winding process. It is also equipped with a cutting structure. During this period, cooling equipment such as fans can be equipped for the air inlet and exhaust joints. When equipped with large fans, the exhaust pipe of the fan can be connected to the air inlet joint through a flange. When equipped with small fans, a fan with a diameter similar to that of the air inlet joint can be selected and directly installed on the air inlet joint through a flange. The exhaust joint can also be equipped with an exhaust fan. After the fan is working, the air in the inner cavity of the inner tube can circulate quickly to carry away the heat of the silicone rubber wires passing through the inner tube and cool them down. The drain pipe and return pipe of the external chiller can be connected to the inlet and outlet connectors respectively, allowing cooling water to flow through the hollow cavity and carry away the heat from the inner tube surface. Furthermore, the heat exchange fins further improve the heat exchange efficiency of the chilled water to the inner tube, creating a better cooling environment for the silicone rubber wires as they pass through the inner tube.

[0007] Specifically, annular cover plates are bolted to both ends of the cooling pipe assembly, and annular rubber sheets are bonded to the inner ring center of the annular cover plates.

[0008] The annular cover plate and the annular rubber sheet on it can provide a certain elastic wrap around the silicone rubber wire passing through the inner tube, providing elastic support for the silicone rubber wire as it passes through the inner tube and avoiding intense friction with the end of the pipe.

[0009] Specifically, the cutting mechanism includes a frame consisting of two sets of side plates, a mounting plate, and a top plate joined together by bolts. The frame has through openings on both sides for silicone rubber wires to pass through. A crescent-shaped cutter is bolted to the top of one of the through openings on one side of the frame. A lifting plate is provided at the bottom of one side of the crescent-shaped cutter. The top of the lifting plate has a notch for the wires to pass through. One end of the lifting plate is rotatably connected to the frame via a pivot.

[0010] Specifically, a servo electric cylinder is installed at the bottom of the frame. The sleeve cylinder at the end of the servo electric cylinder away from the output end is rotatably connected to the frame via a rotating shaft. A rotating arm is installed at the output end of the servo electric cylinder. The top of the rotating arm is rotatably connected to the output end of the servo electric cylinder via a rotating shaft. The top of the rotating arm is rotatably connected to the frame via a rotating shaft. A connecting plate is installed between the rotating arm and the lifting plate. The top of the connecting plate is rotatably connected to one side of the neck of the rotating arm via a rotating shaft. The bottom of the connecting plate is rotatably connected to the other end of the lifting plate via a rotating shaft.

[0011] The servo electric cylinder provides shearing power for cutting the wire. After the output end of the servo electric cylinder is pushed out, the rotating arm will rotate along the pivot at its top and lift one end of the lifting plate based on the connecting plate, so that the silicone rubber wire passing through the frame is lifted and pressure is applied to the crescent-shaped cutter to cut the wire.

[0012] Specifically, the cooling pipe assembly has support bases at both ends of the bottom and pressure caps at both ends of the top. The pressure caps are connected to the support bases by tightening screws.

[0013] Specifically, both the support base and the bottom of the cutting mechanism are equipped with mounting plates. The bottom of the support base and the bottom of the cutting mechanism are fixed to the mounting plates with bolts. In actual use, the mounting plates are installed on the support frame in the work area, and it is ensured that the axial direction of the inner tube is the same as the axial direction of the silicone rubber wire discharged from the previous process.

[0014] The beneficial effects of this utility model are as follows: By combining air cooling and water cooling, the heat exchange area and turbulence effect are greatly increased, and the cooling efficiency is far higher than that of traditional single cooling methods. The cooling and cutting functions are integrated into one unit, and the wire immediately enters the cutting station after cooling, realizing continuous automated operation of cooling, length setting and cutting. This simplifies the production line layout, reduces material transfer, and significantly improves production efficiency. It also significantly improves the cooling efficiency of silicone rubber wires and the degree of automation of the production line. The structure is compact and easy to operate, making it suitable for continuous industrial production. Attached Figure Description

[0019] The present invention also includes annular cover plates 19 bolted to both ends of the cooling pipe assembly 1, and annular rubber sheet 120 is bonded to the inner ring center of the annular cover plate 19.

[0021] This utility model also includes a cutting mechanism 2 comprising a frame 21 consisting of two sets of side plates, a mounting plate and a top plate joined together by bolts. The frame 21 has through openings 22 on both sides for silicone rubber wires to pass through. A crescent-shaped cutter 23 is bolted to the top of the through opening 22 on one side of the frame 21. A lifting plate 24 is provided at the bottom of one side of the crescent-shaped cutter 23. A notch is provided at the top of the lifting plate 24 for wires to pass through. One end of the lifting plate 24 is rotatably connected to the frame 21 via a pivot.

[0022] This utility model also includes a servo electric cylinder 25 disposed at the bottom of the frame 21. The sleeve cylinder at the end of the servo electric cylinder 25 away from the output end is rotatably connected to the frame 21 via a rotating shaft. A rotating arm 26 is disposed at the output end of the servo electric cylinder 25. The top of the rotating arm 26 is rotatably connected to the output end of the servo electric cylinder 25 via a rotating shaft. The top of the rotating arm 26 is rotatably connected to the frame 21 via a rotating shaft. A connecting plate 27 is disposed between the rotating arm 26 and the lifting plate 24. The top of the connecting plate 27 is rotatably connected to one side of the neck of the rotating arm 26 via a rotating shaft. The bottom of the connecting plate 27 is rotatably connected to the other end of the lifting plate 24 via a rotating shaft.

[0023] In use, the servo cylinder 25 provides shearing power for cutting the wire, and after the output end of the servo cylinder 25 is pushed out, the rotating arm 26 will rotate along the rotating shaft at its top, and lift one end of the lifting plate 24 based on the connecting plate 27, so that the silicone rubber wire passing through the frame 21 is lifted and pressure is applied to the crescent-shaped cutter 23 to cut the wire.

[0024] The present invention also includes that the bottom of both ends of the cooling pipe assembly 1 is provided with support bases 31, and the top of both ends of the cooling pipe assembly 1 is covered with pressure caps 32, and the two ends of the pressure caps 32 are connected to the support bases 31 by tightening screws 33.

[0025] This utility model also includes mounting plates at the bottom of both the support base 31 and the cutting mechanism 2. The bottoms of the support base 31 and the cutting mechanism 2 are fixed to the mounting plates by bolts. In actual use, the mounting plates are installed on the support frame in the work area, and it is ensured that the axial direction of the inner tube 12 is the same as the axial direction of the silicone rubber wire discharged from the previous process.

[0026] In use, the mounting plate at the bottom of the support base 31 is fixed to the support frame of the production line with bolts.

Simultaneously, external cold water... The machine's outlet pipe is connected to the inlet connector 17, and the chiller's return pipe is connected to the drain connector 18, forming a closed water circulation cooling circuit. The high-temperature silicone rubber wire coming out of the vulcanizing furnace first passes through the center of the annular cover plate 19 at the feed end of the cooling pipe assembly 1 and enters the inner pipe 12. When the wire travels in the inner pipe 12, it is simultaneously subjected to two cooling effects. Cold air rushes into the inner pipe 12 from the air inlet connector 15, directly blowing on the surface of the wire, carrying away a large amount of heat, and then is discharged from the exhaust connector 16. Cold water is injected from the water inlet connector 17 into the hollow cavity 13 between the outer pipe 11 and the inner pipe 12 and fills the cavity. The cooling water flows continuously, absorbing the heat conducted through the inner tube 12. The heat exchange fins 14 welded to the outer wall of the inner tube 12 greatly enhance the heat exchange area and the turbulence of the water flow, thereby efficiently transferring the heat of the inner tube 12 and its internal wires to the cooling water. The heated water returns to the chiller from the drain connector 18 for cooling and circulation. Through this composite cooling process, the wires are fully cooled when they exit the inner tube 12.
