Description

Technical Field

[0001] This utility model relates to the field of wire extrusion technology, specifically a silicone rubber cable extrusion equipment. Background Technology

[0002] Silicone rubber cables are special cables that use silicone rubber as the main insulation or sheath material. The molecular structure of its core component, polysiloxane, gives it unique properties that combine the high-temperature resistance of inorganic materials with the elasticity of organic materials. It has excellent electrical insulation, weather resistance, chemical corrosion resistance, and is environmentally friendly, low-smoke, and non-toxic. It is widely used in aerospace, power transmission, new energy vehicles, medical equipment, and other fields with extremely high requirements for environmental adaptability and reliability. In the production process of silicone rubber cables, the cooling process plays a decisive role in product quality.

[0003] Traditional silicone rubber cable extrusion equipment relies on a single cooling method and a fixed nozzle angle, which can easily lead to uneven cooling of the silicone rubber, causing stress concentration and surface cracking, thus affecting insulation performance and mechanical strength. Therefore, those skilled in the art have provided a silicone rubber cable extrusion device to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a silicone rubber cable extrusion device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A silicone rubber cable extrusion device includes a working base plate, an angle adjustment structure, and a flow bypass structure. The working base plate has an extruder fixedly connected to its top, a feed hopper at its top, and a discharge pipe at its outlet. A cooling box is fixedly connected to the top of the working base plate and to one side of the extruder. Three rotating shafts are rotatably connected inside the cooling box, and water storage pipes are installed on the rotating shafts. Several nozzles are installed on the water storage pipes. An angle adjustment structure is located at the front end of the cooling box, and a flow bypass structure is located inside the cooling box below the water storage pipes.

[0007] As a further embodiment of this utility model: the angle adjustment structure includes a driven gear, a fixed plate, a first guide rod, a threaded rod, a mounting box, a motor, a first threaded sleeve, and a driving rack. Two fixed plates are fixedly connected to the front end of the cooling box. One end of one fixed plate is fixedly connected to the mounting box, and the motor is fixedly connected inside the mounting box. A threaded rod is rotatably connected between the two fixed plates, and one end of the threaded rod passes through the inside of the mounting box and is fixedly connected to the output end of the motor.

[0008] As a further embodiment of this utility model: a first guide rod is fixedly connected between the two fixed plates, and a first threaded sleeve is threadedly connected to the threaded rod, and three active racks are fixedly connected to the top of the first threaded sleeve, and several rotating shafts are fixedly connected to driven gears through the cooling box at their front ends, and the active racks mesh with the driven gears.

[0009] As a further embodiment of this utility model: the flow-around structure includes a second guide rod, a positive and negative lead screw, and a second threaded sleeve. The second guide rod is fixedly connected inside the cooling box, and the positive and negative lead screw is rotatably connected inside the cooling box. Two second threaded sleeves are threadedly connected to the positive and negative lead screw.

[0010] As a further embodiment of this utility model: one end of the positive and negative lead screw passes through the cooling box and is fixedly connected to the second bevel gear, and one end of the threaded rod passes through the fixing plate and is fixedly connected to the first bevel gear, and the first bevel gear and the second bevel gear are meshed together.

[0011] As a further improvement of this utility model: two rollers are rotatably connected inside the cooling box, and two grooves are opened at the bottom end of the second threaded sleeve, with the rollers located in the grooves.

[0012] As a further improvement of this utility model: a water pump is provided at the top of the working base plate and located behind the cooling box, and the input end of the water pump is connected to the cooling box.

[0013] As a further embodiment of this utility model: a cooler is provided at the top of the working base plate and behind the water pump, and the output end of the water pump is connected to the cooler. The output end of the cooler is connected to three connecting water pipes, and a telescopic hose is provided at the end of the connecting water pipe away from the cooler. The end of the telescopic hose away from the connecting water pipe is connected to a water storage pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This device adjusts the angle of several nozzles by setting up an angle adjustment structure. The motor drives the threaded rod to rotate, which in turn moves the first threaded sleeve and the active rack at its top. The active rack meshes with the driven gear, thereby driving the rotating shaft to rotate. The water storage pipe and nozzle on the rotating shaft also rotate synchronously, realizing the adjustment of the nozzle angle. The wire is sprayed and cooled at different angles, which improves the uniformity of cooling and reduces problems such as internal stress concentration and surface cracking caused by uneven local cooling.

[0016] 2. This device uses a flow-around structure to circulate the water in the cooling tank. When the threaded rod rotates, it drives the first bevel gear to rotate as well. Since the first bevel gear meshes with the second bevel gear, the first bevel gear drives the second bevel gear to rotate, which in turn causes the forward and reverse threaded rods to rotate inside the cooling tank. When the forward and reverse threaded rods rotate, the two second threaded sleeves on them move relative to each other or in opposite directions along the forward and reverse threaded rods under the guidance of the second guide rod. The movement of the second threaded sleeves changes the path of the water flow in the cooling tank, causing the water flow to circulate, increasing water turbulence, enhancing convective heat transfer, and improving cooling efficiency.

Detailed Implementation

[0023] 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.

[0024] Example 1: Refer to Figure 1-5This embodiment provides a silicone rubber cable extrusion device, including a working base plate 1, an angle adjustment structure, and a flow-around structure. The working base plate 1 is characterized by having an extruder 2 fixedly connected to its top, a feed hopper 3 at the top of the extruder 2, and a discharge pipe 27 at the outlet of the extruder 2. A cooling box 4 is fixedly connected to the top of the working base plate 1 and located on one side of the extruder 2. Three rotating shafts 5 are rotatably connected inside the cooling box 4, and water storage pipes 6 are installed on the rotating shafts 5. Several nozzles 7 are installed on the water storage pipes 6. An angle adjustment structure is located at the front end of the cooling box 4, and a flow-around structure is located inside the cooling box 4 and below the water storage pipes 6.

[0025] The angle adjustment structure includes a driven gear 8, a fixed plate 9, a first guide rod 10, a threaded rod 11, a mounting box 13, a motor 14, a first threaded sleeve 15, and a drive rack 16. Two fixed plates 9 are fixedly connected to the front end of the cooling box 4. One end of one fixed plate 9 is fixedly connected to the mounting box 13, and the motor 14 is fixedly connected inside the mounting box 13. The threaded rod 11 is rotatably connected between the two fixed plates 9, and one end of the threaded rod 11 passes through the mounting box 13 and is fixedly connected to the output end of the motor 14.

[0026] A first guide rod 10 is fixedly connected between the two fixed plates 9, and a first threaded sleeve 15 is threadedly connected to the threaded rod 11. Three active racks 16 are fixedly connected to the top of the first threaded sleeve 15, and several rotating shafts 5 are all fixedly connected to driven gears 8 through the cooling box 4 at their front ends. The active racks 16 mesh with the driven gears 8.

[0027] The cooling box 4 has two rotating rollers 17 inside. The bottom end of the second threaded sleeve 21 has two grooves 22, and the rollers 17 are located in the grooves 22. A water pump 23 is set at the top of the working base plate 1 and at the rear of the cooling box 4. The input end of the water pump 23 is connected to the cooling box 4. A cooler 24 is set at the top of the working base plate 1 and at the rear of the water pump 23. The output end of the water pump 23 is connected to the cooler 24. The output end of the cooler 24 is connected to three connecting water pipes 25. A telescopic hose 26 is set at the end of the connecting water pipes 25 away from the cooler 24. The end of the telescopic hose 26 away from the connecting water pipes 25 is connected to the water storage pipe 6.

[0028] In this implementation, silicone rubber raw material is fed into extruder 2 through feed hopper 3. Under the rotation and extrusion of the screw and the heating of the barrel within extruder 2, the raw material is plasticized into a molten state and extruded through discharge pipe 27 to form a continuous cable wire. The freshly extruded high-temperature wire falls vertically into cooling tank 4, where it is cooled. Water pump 23 draws water from cooling tank 4 and transports it through pipelines to chiller 24 for further cooling. The cooled water then enters water storage pipe 6 through connecting water pipe 25 and telescopic hose 26, and is sprayed out by nozzle 7 to cool the wire. The cooled water flows back into cooling tank 4, forming a circulating cooling system that avoids water waste. When the material is cooled, the motor 14 can be started. The output end of the motor 14 drives the threaded rod 11 to rotate between the two fixed plates 9. When the threaded rod 11 rotates, the first threaded sleeve 15, which is threaded to it, moves along the axial direction of the threaded rod 11 under the guidance of the first guide rod 10. The active rack 16 at the top of the first threaded sleeve 15 moves accordingly and meshes with the driven gear 8 at the front end of the rotating shaft 5, thereby driving the rotating shaft 5 to rotate. The water storage pipe 6 and the nozzle 7 on the rotating shaft 5 also rotate synchronously, realizing the adjustment of the nozzle 7 angle. The wire is sprayed and cooled at different angles to improve the uniformity of cooling and reduce problems such as internal stress concentration and surface cracking caused by uneven local cooling.

[0029] Example 2: Refer to Figure 1-5 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the flow-around structure includes a second guide rod 18, a positive and negative lead screw 19, and a second threaded sleeve 21. The second guide rod 18 is fixedly connected inside the cooling box 4, and the positive and negative lead screw 19 is rotatably connected inside the cooling box 4. Two second threaded sleeves 21 are threadedly connected to the positive and negative lead screw 19.

[0030] One end of the positive and negative lead screw 19 passes through the cooling box 4 and is fixedly connected to the second bevel gear 20. One end of the threaded rod 11 passes through the fixing plate 9 and is fixedly connected to the first bevel gear 12. The first bevel gear 12 and the second bevel gear 20 are meshed together.

[0031] In this embodiment, the wire entering the cooling box 4 falls directly onto the surface of the roller 17. The wire is moved by an external traction device. The two rollers 17 improve the conveying effect of the wire in the cooling box 4. When the threaded rod 11 rotates, the first bevel gear 12 at one end rotates accordingly. Since the first bevel gear 12 meshes with the second bevel gear 20 at one end of the positive and negative threaded rod 19, the first bevel gear 12 drives the second bevel gear 20 to rotate, thereby causing the positive and negative threaded rod 19 to rotate inside the cooling box 4. When the positive and negative threaded rod 19 rotates, the two second threaded sleeves 21 on it move relative to or away from each other along the positive and negative threaded rod 19 under the guidance of the second guide rod 18. When the two second threaded sleeves 21 approach each other, they can effectively push the deviated wire back to the center position of the cooling box 4. At the same time, the movement of the second threaded sleeves 21 changes the path of the water flow in the cooling box 4, causing the water flow to have a bypass effect, increasing water turbulence, enhancing convective heat transfer, and improving cooling efficiency.
