[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the present application, the core wire is preheated by a core wire preheating device before extrusion. On the one hand, the bonding performance of the core wire can be improved by the orientation symmetry between the grains. On the other hand, it is helpful to remove moisture on the surface of the core wire and avoid the generation of bubbles in the PEEK layer. In addition, it is helpful to reduce the temperature difference between the core wire and the PEEK layer during extrusion, thereby improving the adhesion of the PEEK layer. After the PEEK insulated wire is extruded, it is cooled by a cooling device to promote the cooling and molding of the PEEK layer. Since the cooling crystallization of the PEEK layer rubber is a shrinkage process, when the insulation thickness is relatively thick, the inner and outer sides of the insulation layer shrink asynchronously, and the shrinkage force generated when the outer rubber is cooled causes the inner side to be stretched outward, resulting in reduced adhesion. In view of the cooling crystallization characteristics of the PEEK layer, a plurality of cooling chambers are provided in the cooling container of the present application. While ensuring the cooling efficiency, a plurality of cooling chambers with gradually decreasing cooling temperatures are provided on the rear side of the die head, so that the cooling temperature of the PEEK layer can be gradually reduced after the PEEK insulated wire is extruded, thereby helping to reduce the temperature difference between the inner and outer sides of the PEEK layer, making the cooling process of the PEEK insulated wire more moderate, improving the crystallization state of the PEEK layer, and further helping to improve the adhesion of the PEEK insulation layer on the wire and the service life of the PEEK insulated wire.
[0016] 2. In this application, the surface of the PEEK insulated wire is dried by a drying container. In this application, the temperature of the coolant in the cooling zone rises after the insulated wire is cooled. The temperature of the liquid in the cooling zone with the highest cooling temperature is detected online by a temperature sensor. When the liquid temperature in the cooling zone reaches a preset value, the control valve is opened by a signal control to avoid the temperature of the coolant in the cooling zone being too high, thereby ensuring a stable and controllable cooling efficiency. The coolant in the cooling zone is discharged into the gas-liquid heat exchanger through the discharge pipe. The gas-liquid heat exchanger is used to exchange heat between the air introduced by the induced draft fan and the coolant, thereby realizing the recovery of waste heat from the coolant and improving energy efficiency. The hot air is then discharged through the blower mechanism to improve the drying efficiency of the PEEK insulated wire in the drying container.
[0017] 3. In this application, the spray mechanism can input the coolant of the corresponding cooling temperature into the corresponding cooling chamber. By adjusting the side baffle up and down, the liquid level in the cooling chamber can be adjusted. When the preset liquid level is reached, the coolant in the cooling chamber can overflow from the side discharge hole and be stored in the storage container. Since the temperature of the coolant in each cooling chamber increases after cooling the insulated wire, the coolant in the storage container can be pumped to the previous cooling chamber by the pump, thereby realizing the circulation of the coolant in each cooling chamber. It has a thermal circulation structure, which is convenient for energy saving and energy efficiency improvement.
[0018] 4. The present application can flush both sides of the PEEK insulated wire through a flushing pipe and a flushing nozzle, thereby improving the cooling efficiency and achieving the purpose of cleaning the outer surface of the insulation layer to ensure the cleanliness of the surface of the PEEK insulated wire. The two flushing pipes can be rotated and adjusted synchronously through the rotation adjustment mechanism, and the flushing nozzles on both sides can be rotated and adjusted synchronously to improve the adjustment efficiency of the flushing nozzle direction to adapt to PEEK insulated wires with different outer diameters and improve the applicability of the flushing nozzle.
[0019] 5. In addition to the drying function, the drying container in this application can also reheat the PEEK insulated wire after extrusion and cooling. On the one hand, it can facilitate the softening of the PEEK material at an appropriate temperature, so that the PEEK insulated wire can be further heat-set after cooling to achieve fine-tuning of the size and shape; on the other hand, since the PEEK material is prone to internal stress during the cooling process, reheating can relax the PEEK material molecular chain to a certain extent, which is convenient for the release of internal stress, thereby improving the mechanical properties and long-term stability of the PEEK insulated wire. In addition, reheating can further improve the crystallinity of the PEEK material, which is beneficial to improving the adhesion of the PEEK layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-11 , further details of this application are given.
[0033] Example:
[0034] The present application embodiment discloses a high-adhesion PEEK insulated wire production device. Figure 1 A high-adhesion PEEK insulated wire production device includes an extruder 1, a head mold 2 is installed at the output end of the extruder 1, one end of the head mold 2 is provided with a wire inlet 21, and the other end is provided with a wire outlet 22. A core wire preheating device 3 is provided on one side of the wire inlet 21 of the head mold 2, and a cooling device 4 is provided on one side of the wire outlet 22 of the head mold 2.
[0035] Before the core wire contacts the PEEK material, the core wire is preheated by the core wire preheating device 3. On the one hand, the bonding performance of the core wire can be improved by the orientation symmetry between the grains. On the other hand, it is helpful to remove moisture on the surface of the core wire and avoid the generation of bubbles in the PEEK layer. In addition, it is helpful to reduce the temperature difference between the core wire and the PEEK layer during extrusion, thereby improving the adhesion of the PEEK layer.
[0036] Reference Figure 2The cooling device 4 includes a cooling container 41 arranged along the direction of the insulating wire. The cooling container 41 is divided into a plurality of cooling chambers 42 along its length direction. The cooling temperatures of the plurality of cooling chambers 42 are set to decrease step by step along the direction of the insulating wire. A plurality of spray mechanisms 43 are installed on the cooling container 41. The spray mechanisms 43 are arranged one by one corresponding to the cooling chambers 42 to spray coolants of different temperatures toward the insulating wire. In this embodiment, the cooling container 41 is a cooling water tank.
[0037] After the PEEK insulated wire is extruded, it is cooled by the cooling device 4 to promote the cooling and forming of the PEEK layer. Since the cooling crystallization of the PEEK layer rubber is a shrinkage process, when the insulation thickness is relatively thick, the inner and outer sides of the insulation layer shrink asynchronously, and the shrinkage force generated when the outer rubber is cooled causes the inner side to be stretched outward, resulting in reduced adhesion. In view of the cooling crystallization characteristics of the PEEK layer, a plurality of cooling chambers 42 are provided in the cooling container 41 of the present application. While ensuring the cooling efficiency, a plurality of cooling chambers 42 with gradually decreasing cooling temperatures are provided on the rear side of the die head mold 2. After the PEEK insulated wire is extruded, the cooling temperature of the PEEK layer can be gradually reduced, which is conducive to reducing the temperature difference between the inner and outer sides of the PEEK layer, making the cooling process of the PEEK insulated wire more moderate, improving the crystallization state of the PEEK layer, and then helping to improve the adhesion of the PEEK insulation layer on the wire and the service life of the PEEK insulated wire.
[0038] Reference Figure 2-4 , a side hole 421 is provided on one side of each cooling chamber 42, each side hole 421 is connected to a storage container 44, a side baffle 411 is installed on the cooling container 41 for blocking the side hole 421, the side baffle 411 is slidably arranged on the cooling container 41, and can be locked and fixed on the cooling container 41 by a locking bolt to adjust the liquid level in the cooling chamber 42. In this embodiment, the storage container 44 is a heat preservation water storage tank.
[0039] Reference Figure 2-4, the storage container 44 is connected to a pump 45. The cooling chamber 42 with a higher cooling temperature among the two adjacent cooling chambers 42 is located at the front end of the cooling container 41. The input end of each pump 45 is connected to the corresponding cooling chamber 42, and the output end is connected to the previous cooling chamber 42. In the present application, the cooling liquid of the corresponding cooling temperature can be input into the corresponding cooling chamber 42 through the spray mechanism 43. The liquid level in the cooling chamber 42 can be adjusted by adjusting the side baffle 411 up and down. When the preset liquid level is reached, the cooling liquid in the cooling chamber 42 can overflow from the side discharge hole 421 and be stored in the storage container 44. Since the temperature of the cooling liquid in each cooling chamber 42 increases after the insulated wire is cooled, the cooling liquid in the storage container 44 can be pumped to the previous cooling chamber 42 by the pump 45, thereby realizing the circulation of the cooling liquid in each cooling chamber 42. It has a thermal circulation structure, which is convenient for energy saving and energy efficiency improvement.
[0040] Reference Figure 1 and Figure 5-6 A drying container 5 is provided on the side of the cooling container 41 away from the die head 2. The drying container 5 is arranged along the direction of the insulating wire. Both ends of the drying container 5 are provided with wire holes 51 for the insulating wire to pass through. A blower mechanism 52 is provided in the drying container 5 and is arranged toward the insulating wire. To prevent the insulating wire from being scratched at the wire holes 51, two inner ends of the drying container 5 are provided with guide rollers 53 in the shape of a cross. The middle opening of the guide rollers 53 in the shape of a cross can be opened and closed according to the outer diameter of the PEEK insulating wire. In this embodiment, the drying container 5 is a box structure with a box cover; the blower mechanism 52 is a bellows-type blower.
[0041] Reference Figure 2-4 A temperature sensor 46 is installed on the side wall of the cooling container 41, and the detection end of the temperature sensor 46 extends into the cooling chamber 42 with the highest cooling temperature. The cooling chamber 42 with the highest cooling temperature is connected to a discharge pipe 47, and a control valve 471 is installed on the discharge pipe 47. The control valve 471 is connected to the temperature sensor 46 by signal. In this embodiment, the control valve 471 is a solenoid valve.
[0042] Reference Figure 7 The end of the discharge pipe 47 away from the cooling container 41 is connected to the gas-liquid heat exchanger 6, the liquid inlet 61 of the gas-liquid heat exchanger 6 is connected to the discharge pipe 47, and the liquid outlet 62 of the gas-liquid heat exchanger 6 is connected to the liquid reservoir 621 to facilitate the recycling of the coolant; the air inlet 63 of the gas-liquid heat exchanger 6 is connected to the induced draft fan 631, and the air outlet 64 of the gas-liquid heat exchanger 6 is connected to the blower mechanism 52.
[0043] In the present application, the surface of the PEEK insulated wire is dried by a drying container 5. In the present application, the temperature of the coolant in the cooling chamber 42 rises after the insulated wire is cooled. The temperature of the liquid in the cooling chamber 42 with the highest cooling temperature is detected online by a temperature sensor 46. When the liquid temperature in the cooling chamber 42 reaches a preset value, the control valve 471 is opened by a signal control to avoid the temperature of the coolant in the cooling chamber 42 being too high, thereby ensuring a stable and controllable cooling efficiency. The coolant in the cooling chamber 42 is discharged into the gas-liquid heat exchanger 6 through the discharge pipe 47. The gas-liquid heat exchanger 6 is used to allow the air introduced by the induced draft fan 631 to exchange heat with the coolant, thereby realizing the recycling of waste heat from the coolant and improving energy efficiency. The hot air is then discharged through the blower mechanism 52 to improve the drying efficiency of the drying container 5 for the PEEK insulated wire.
[0044] In addition to improving the drying efficiency of the drying container 5 for the PEEK insulation wire, it is worth noting that the hot air discharged by the blower mechanism 52 can fill the drying container 5 with hot air, thereby achieving reheating of the PEEK insulation wire. The reheating of the PEEK insulation wire after extrusion and cooling has the following advantages: First, during the cooling process after extrusion, the PEEK insulated wire may have certain deviations in size or irregular shapes due to factors such as uneven cooling speed and internal stress. Reheating it can soften the outer layer of PEEK material at an appropriate temperature, and its size can be fine-tuned by external force and other means to better achieve the required precise size specifications. At the same time, the internal molecular chains have a chance to rearrange and further shape the shape to ensure the final dimensional stability of the PEEK insulated wire. For example, a shaping mold for further heat-setting the PEEK insulated wire can be installed at the wire hole 51 at the outlet of the drying container 5, thereby reducing problems caused by inappropriate size in subsequent use; Secondly, when the PEEK wire is extruded and cooled, internal stress will be generated due to the different cooling rates inside and outside the material due to the rapid cooling from high temperature to low temperature. The existence of this internal stress may cause problems such as cracking and deformation of the product during subsequent use. When reheating, the molecular chains of the PEEK material can relax to a certain extent, and the internal stress can be released, thereby improving the mechanical properties and long-term stability of the PEEK insulation wire; Thirdly, the crystallinity of the PEEK layer can be further improved, thereby further improving the adhesion of the PEEK layer and increasing the service life of the PEEK insulated wire.
[0045] Reference Figure 6 and Figure 8A sponge layer 54 is provided inside the drying container 5. The sponge layer 54 has a heat preservation function, which is beneficial to reducing the heat loss of the drying container 5 and improving the drying efficiency of the insulated wire. On the other hand, the sponge layer 54 has a sound absorption effect, which can effectively reduce the noise generated by the air blowing mechanism 52. In order to prevent the water from wetting the sponge layer 54 and causing the noise reduction to fail, a water retaining plate 55 is installed inside the sponge layer 54.
[0046] Reference Figure 2 and Fig. 9 A surface cleaning chamber 48 is provided at one end of the cooling container 41 close to the drying container 5. Two flushing pipes 481 are rotatably provided in the surface cleaning chamber 48. The two flushing pipes 481 are relatively arranged on both sides of the insulating wire and arranged along the length direction of the cooling container 41. A plurality of flushing nozzles 482 are provided on the opposite sides of the two flushing pipes 481. A rotating adjustment mechanism 7 for driving the two flushing pipes 481 to rotate toward each other is provided on the cooling container 41.
[0047] The present application can flush both sides of the PEEK insulation wire through the flushing tube 481 and the flushing nozzle 482, thereby improving the cooling efficiency and achieving the purpose of cleaning the outer surface of the insulation layer to ensure the cleanliness of the surface of the PEEK insulation wire. The two flushing tubes 481 can be rotationally adjusted synchronously through the rotation adjustment mechanism 7, and the flushing nozzles 482 on both sides can be rotationally adjusted synchronously to improve the adjustment efficiency of the direction of the flushing nozzle 482 to adapt to PEEK insulation wires with different outer diameters and improve the applicability of the flushing nozzle 482.
[0048] Reference Figure 9-10 The rotation adjustment mechanism 7 includes a pair of passive synchronous wheels 71 coaxially fixed with two flushing pipes 481, two double synchronous wheels 72 are rotatably connected to the cooling container 41, the large diameter ends of the two double synchronous wheels 72 are meshed, and the small diameter ends of the two double synchronous wheels 72 are respectively connected to the adjacent passive synchronous wheels 71 through the synchronous belt 73. The small diameter end of one of the double synchronous wheels 72 is fixed with an adjustment crank 74, and the cooling container 41 is also provided with a locking mechanism 8 for locking the double synchronous wheels 72. When the flushing nozzle 482 is rotationally adjusted, the locking function of the locking mechanism 8 is first released, and the adjustment crank 74 is rotated to drive the corresponding double synchronous wheel 72 to rotate, and then drive the other double synchronous wheel 72 to rotate synchronously. Since the large diameter ends of the two double synchronous wheels 72 are meshed, the two double synchronous wheels 72 rotate in opposite directions, and the rotation of the double synchronous wheel 72 drives the adjacent passive synchronous wheel 71 to rotate through the corresponding synchronous belt 73, thereby achieving the purpose of synchronously rotating the two flushing pipes 481 in opposite directions.
[0049] Reference Figure 9-11The locking mechanism 8 includes a locking head 81 and a locking bolt 82 connected to the locking head 81. A fixing plate 83 is fixed to the outside of the cooling container 41. The locking bolt 82 is slidably penetrated on the fixing plate 83. The locking head 81 is meshed with the large diameter end of one of the double synchronous wheels 72. An elastic member 84 is sleeved on the locking bolt 82. One end of the elastic member 84 abuts against the back of the locking head 81, and the other end abuts against the fixing plate 83. In this embodiment, the elastic member 84 is a helical compression spring. In this way, by pulling the locking bolt 82, the elastic member 84 is compressed, and the locking head 81 is disengaged from the corresponding double synchronous wheel 72, so that the locking mechanism 8 can be unlocked. In the unlocked state, the two flushing pipes 481 can be synchronously rotated in opposite directions. After completing the rotation adjustment of the flushing nozzles 482 on both sides, release the locking pull bolt 82, reset the elastic member 84, and engage the locking head 81 with the large diameter end of the corresponding double synchronous wheel 72 to lock the double synchronous wheel 72, thereby preventing the flushing nozzles 482 on both sides of the PEEK insulated wire from rotating at will during use, thereby affecting the flushing efficiency.
[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
