Description

Technical Field

[0001] This utility model belongs to the field of cable production technology, and in particular relates to a cable extrusion cooling and shaping guide device. Background Technology

[0002] The core function of cable extrusion cooling and shaping is to quickly solidify and shape the extruded high-temperature cable insulation or sheath layer, ensuring that it achieves the designed dimensional accuracy and physical properties. The cable is in a high-temperature molten state when it comes out of the extruder die, and its shape is unstable. Cooling and shaping uses water inside the water tank to quickly reduce the temperature of the insulation or sheath layer below the melting point, so that it solidifies into the set cross-sectional shape, such as a circle or a sector. At the same time, it controls key dimensions such as the cable outer diameter and insulation thickness to avoid dimensional deviations caused by material shrinkage or deformation. Efficient cooling can quickly remove the heat from the insulation or sheath layer, so that the cable can quickly reach a state that can be processed later (such as pulling and winding), avoiding cable adhesion or damage due to insufficient cooling.

[0003] After the cable is extruded, cooled, and shaped, it needs to be wound up. Currently, to prevent the cable from rubbing against the water tank, guide rollers are mostly used to guide the cable. However, during winding, the cable will swing to adapt to the width of the winding roller. The guide roller is generally fixed, and the cable will rub against the edge of the guide roller when it swings, affecting the surface quality of the finished cable. In view of this, we propose a cable extrusion cooling and shaping guiding device. Utility Model Content

[0005] In view of this, the present invention provides a cable extrusion cooling and shaping guide device, comprising: a water tank, a support roller, a cable body and a bracket, wherein the water tank is fixedly installed above the bracket, the support roller is disposed inside the water tank, a wire hole is opened on the inner side of the water tank, the cable body is located inside the wire hole, and the outer surface of the cable body is in contact with the outer surface of the support roller.

[0006] A first support base is fixedly connected to one side of the water tank. Two first guide rollers are rotatably connected to the inner wall of the first support base, and the two first guide rollers are symmetrical vertically. Two first limiting rollers are rotatably connected to the inner wall of the first support base, and the two first limiting rollers are symmetrical horizontally. The cable body is located inside the two first guide rollers and the first limiting rollers.

[0007] The inner wall of the first support base is hinged to a second support base. The inner wall of the second support base is rotatably connected to two second guide rollers, which are symmetrical from left to right. The inner wall of the second support base is also rotatably connected to two second limiting rollers, which are symmetrical from top to bottom. The cable body is located inside the two second guide rollers and the two limiting rollers.

[0008] In this technical solution, the cable body is supported by the second limiting roller and the first limiting roller to prevent the cable body from contacting the edge positions of the second guide roller and the first guide roller.

[0009] In the above technical solution, a drain pipe is fixedly connected to the bottom of the water tank, and a valve is fixedly installed at the end of the drain pipe.

[0010] In this technical solution, the water inside the tank is easily drained through the drain pipe.

[0011] In the above technical solution, further, the inner wall of the water tank is fixedly connected to a first base, and the inner wall of the first base is rotatably connected to the end of the support roller.

[0012] In this technical solution, the first base provides support force for the support roller.

[0013] In the above technical solution, the number of support rollers is multiple, and the multiple support rollers are arranged at equal distances.

[0014] In this technical solution, multiple support rollers provide segmented support force for the cable body.

[0015] In the above technical solution, a second base is fixedly connected to the inner wall of the water tank, and a pressure roller is rotatably connected to the inner wall of the second base.

[0019] The beneficial effects of this utility model are:

[0020] 1. This cable extrusion cooling and shaping guide device, through the cooperation between the second support seat, the second guide roller and the second limiting roller, the second support seat has the function of changing the angle through the support of the first support seat. By changing the angle, the second guide roller and the second limiting roller change together with the moving direction of the cable body. The cable body, through the support of the second limiting roller, keeps the position of the cable body close to the second guide roller unchanged, so that the cable body cannot contact the edge of the second guide roller, reducing the contact between the edge of the second guide roller and the cable body, reducing the scratching of the cable body, and improving the surface quality of the insulation layer of the cable body.

[0021] 2. The cable extrusion cooling and shaping guide device, through the cooperation between the second base, the pressure roller and the cable body, provides support force to the pressure roller through the second base to maintain the stability of the pressure roller, and provides a limiting function above the cable body through the pressure roller to prevent the cable body from detaching from the support roller at a higher position, thereby improving the stability of the cable body during transportation.

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0031] Example 1: This example provides a cable extrusion cooling and shaping guide device, including: a water tank 1, a support roller 2, a cable body 3, and a bracket 4. The water tank 1 is fixedly installed above the bracket 4. The support roller 2 is disposed inside the water tank 1. A wire hole 5 is opened on the inner side of the water tank 1. The cable body 3 is located inside the wire hole 5. The outer surface of the cable body 3 is in contact with the outer surface of the support roller 2. The water tank 1 provides space for the cable body 3 to pass through and exit through the wire hole 5. The water tank 1 also provides storage space for the water used for cooling.

[0032] A first support base 6 is fixedly connected to one side of the water tank 1. Two first guide rollers 7 are rotatably connected to the inner wall of the first support base 6, and the two first guide rollers 7 are symmetrical vertically. Two first limiting rollers 8 are rotatably connected to the inner wall of the first support base 6, and the two first limiting rollers 8 are symmetrical horizontally. The cable body 3 is located inside the two first guide rollers 7 and the first limiting rollers 8. The first support base 6 provides support for the first guide rollers 7 and the first limiting rollers 8, maintaining the stability of the first guide rollers 7 and the first support roller 2. The first limiting rollers 8 can provide rolling support for the cable body 3, reducing the scraping friction between the cable body 3 and the first guide rollers 7. When the cable body 3 changes direction to the left or right, the support of the first limiting rollers 8 keeps the position of the cable body 3 close to the first guide rollers 7 in its original posture, preventing the cable body 3 from contacting the edge of the first guide rollers 7, reducing the contact between the edge of the first guide rollers 7 and the cable body 3, and reducing scraping.

[0033] The inner wall of the first support seat 6 is hinged to the second support seat 9. The inner wall of the second support seat 9 is rotatably connected to two second guide rollers 10, which are symmetrical from left to right. The inner wall of the second support seat 9 is rotatably connected to two second limiting rollers 11, which are symmetrical from top to bottom. The cable body 3 is located inside the two second guide rollers 10 and the second limiting rollers 11.

[0034] Specifically, the second support seat 9 provides support for the second guide roller 10 and the second limiting roller 11, maintaining the stability of the second guide roller 10 and the second support roller 2. The first support seat 6 supports the second support seat 9, enabling the second support seat 9 to swing and adjust its angle. When the moving direction and angle of the cable body 3 change, the second support seat 9 moves its position together with the direction of the cable body 3. With the support of the second limiting roller 11, the position of the cable body 3 near the second guide roller 10 maintains its original posture, preventing the cable body 3 from contacting the edge of the second guide roller 10, reducing the contact between the edge of the second guide roller 10 and the cable body 3, and further reducing scratches.

[0035] Example 2: This example provides a cable extrusion cooling and shaping guide device. In addition to the technical solutions of the above examples, it also has the following technical features: a drain pipe 12 is fixedly connected to the bottom of the water tank 1, and a valve 13 is fixedly installed at the end of the drain pipe 12.

[0036] When it is necessary to replace the water inside the water tank 1, the water inside the water tank 1 can be drained through the drain pipe 12, and the opening and closing of the drain pipe 12 can be controlled by the valve 13.

[0037] Example 3: This example provides a cable extrusion cooling and shaping guide device. In addition to the technical solutions of the above examples, it also has the following technical features: the inner wall of the water tank 1 is fixedly connected to a first base 14, and the inner wall of the first base 14 is rotatably connected to the end of the support roller 2.

[0038] The first base 14 provides support for the support roller 2, thereby maintaining the stability of the support roller 2.

[0039] Example 4: This example provides a cable extrusion cooling and shaping guide device. In addition to the technical solutions of the above examples, it also has the following technical features: the number of support rollers 2 is multiple, and the multiple support rollers 2 are arranged at equal distances.

[0040] Among them, multiple support rollers 2 form segmented support for the cable body 3, reducing the sag of the cable body 3 and improving the stability of the cable body 3 during transportation.

[0041] Example 5: This example provides a cable extrusion cooling and shaping guide device. In addition to the technical solutions of the above examples, it also has the following technical features: a second base 15 is fixedly connected to the inner wall of the water tank 1, and a pressure roller 16 is rotatably connected to the inner wall of the second base 15.

[0042] The pressure roller 16 provides a limiting function above the cable body to prevent the cable body 3 from detaching from the support roller 2, which is positioned higher.

[0043] Example 6: This example provides a cable extrusion cooling and shaping guide device. In addition to the technical solutions of the above examples, it also has the following technical features: the pressure roller 16 is located above one of the support rollers 2, and the outer surface of the pressure roller 16 is in contact with the outer surface of the cable body 3.

[0044] One of the support rollers 2 is at a higher height. The support roller 2 at a higher position supports the cable body 3, aligning the center position of the cable body 3 with the center position of the wire hole 5, so that the cable body 3 can pass through the water tank 1. The pressure roller 16 at a higher height raises and supports the cable body 3, aligning the center position of the cable body 3 with the center position of the wire hole 5, so that the cable body 3 can be smoothly moved out of the water tank 1, and preventing the cable body 3 from scratching the wire hole 5.

[0045] Working principle: First, when the cable body 3 moves, the cable body 3 will swing left and right with the winding roller. At the same time, the second support seat 9 will also swing along with the swing direction of the cable body 3. At this time, the second limiting roller 11 on the swing direction side of the cable body 3 will restrict the cable body 3 from approaching the edge of the second guide roller 10 through the support of the second limiting roller 11, so that the edge of the second guide roller 10 cannot contact the cable body 3.
