Description

Technical Field

[0001] The utility model relates to the technical field of cable sheath production, and particularly relates to a rapid cooling device for cable sheaths. Background Art

[0002] A cable sheath refers to a layer of material wrapped between the shielding layer and the core of a cable, which is used to protect the core and shielding layer inside the cable and prevent the influence of the external environment on the inside of the cable. The selection of the thickness and material of the cable sheath depends on the use environment and working conditions of the cable, such as the working temperature of the cable, the voltage level of the cable, the use environment of the cable, etc.

[0003] When a cable is being produced and processed, the cable material needs to be heated to form a fluid, and the fluid is coated on the outer surface of the cable core through an extrusion device to form an insulating protective sleeve, and then the cable is cooled down. In most traditional methods, after the cable is extruded with a sheath, the cable is directly immersed in a cold water sink for cooling.

[0004] For example, the Chinese utility model patent with the patent number 201720783038.X provides a new type of cable sheath cooling device, which includes a high-temperature water tank, a medium-temperature water tank, and a low-temperature water tank arranged in parallel. All three water tanks are rectangular structures, and a first turning wheel is provided in each of the three water tanks. The first turning wheels are located below the water surface and are arranged staggeredly. The cable sheath is gradually cooled level by level to prevent pits on the surface of the cable sheath caused by sudden temperature difference changes, ensuring the quality of the cable. After the water in the low-temperature water tank gets hot, it can be transported to the water tank with a higher temperature for secondary use.

[0005] However, since the cooling time of the cable sheath needs to be controlled, if the cooling time is too short, the cooling will be insufficient and it cannot be put into use. Most of the cooling water has a relatively low temperature. If the cooling time is too long, the cable sheath will crack due to the lack of the action of bending prestress or molecular structural force, affecting the service life of the cable sheath. And when the cable sheath is being cooled, its conveying speed needs to be kept constant. The existing cooling equipment for cable sheath production is not convenient for controlling the contact time between the sheath and the cooling water according to the material or size of the sheath, resulting in a decrease in its applicable range. Summary of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the utility model proposes a rapid cooling device for cable sheaths to solve the technical problem that the existing cooling equipment for cable sheath production is not convenient for adjusting the contact time between the sheath and the cooling water according to the material or size of the sheath, resulting in a decrease in its applicable range as mentioned in the above background art.

[0007] To achieve the above object, the utility model provides the following technical solution. A rapid cooling device for cable sheaths includes:

[0008] A water tank, on which two sets of first guide wheels and two sets of second guide wheels are arranged, and the second guide wheels are arranged staggeredly with the first guide wheels;

[0009] A third guide wheel, arranged inside the water tank, and the height of the third guide wheel is lower than the water level of the water tank;

[0010] A cable sheath, extending into the water tank through the guidance of one set of the first guide wheels and the second guide wheels, and extending out of the water tank through the guidance of the other set of the first guide wheels and the second guide wheels; and

[0011] An adjusting mechanism, arranged inside the water tank and connected to the third guide wheel to adjust the distance between the third guide wheel and the second guide wheel.

[0012] In a preferred embodiment, a mounting seat is arranged inside the water tank, a mounting wheel is hinged on the mounting seat, the third guide wheel is rotatably sleeved on the mounting wheel along its axis, and the adjusting mechanism is connected to the mounting seat.

[0013] In a preferred embodiment, a plurality of sets of rotatable balls are embedded inside the mounting wheel, a guiding groove is formed on the third guide wheel, and the balls are clamped in the guiding groove.

[0014] In a preferred embodiment, the adjusting mechanism includes:

[0015] A connecting seat, arranged on the mounting seat;

[0016] A lead screw, rotatably arranged inside the water tank along its axis and screwed to the connecting seat; and

[0018] In a preferred embodiment, a guiding sleeve is arranged on the mounting seat, a guiding rod is arranged inside the water tank, and the guiding sleeve is slidably sleeved on the guiding rod along the axis of the guiding rod.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] When in use, the cable sheath is guided into the water tank through a set of first guide wheels and second guide wheels, and extends out of the water tank through another set of first guide wheels and second guide wheels. Cooling water is added into the water tank to cool the cable sheath. The cable sheath is driven to move by an external wire winding mechanism, and the cable sheath can be guided out of the next-stage cooling device through the first guide wheel to achieve multi-stage cooling of the cable sheath.

[0030] The embodiments of the technical solutions of the present invention will be described in detail below with reference to the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0031] Embodiment:

[0032] As Figure 1 、 2 shown, the present utility model provides a rapid cooling device for a cable sheath, which includes a water tank 101. Two sets of first guide wheels 102 and two sets of second guide wheels 103 are arranged on the water tank 101. The second guide wheels 103 and the first guide wheels 102 are arranged in a staggered manner. A third guide wheel 304 is arranged in the water tank 101, and the height of the third guide wheel 304 is lower than the water level of the water tank 101.

[0033] During use, cooling water is circulated into the water tank 101. The cable sheath 104 is guided into the water tank 101 through one set of the first guide wheels 102 and the second guide wheels 103, and is guided out of the water tank 101 through the other set of the first guide wheels 102 and the second guide wheels 103. One end of the cable sheath 104 extending out of the water tank 101 can be connected to a take-up device or can be connected to a next-stage cooling device to achieve multi-stage cooling of the cable sheath 104.

[0034] As Figure 3 、 4 shown, in this embodiment, a mounting seat 201 is arranged in the water tank 101. A mounting wheel 301 is hinged on the mounting seat 201. The third guide wheel 304 is rotatably sleeved on the mounting wheel 301 along its axis. An adjusting mechanism connected to the third guide wheel 304 is arranged in the water tank 101, and the distance between the third guide wheel 304 and the second guide wheel 103 can be adjusted through the adjusting mechanism. The adjusting mechanism is connected to the mounting seat 201. The adjusting mechanism includes a connecting seat 204 on the mounting seat 201. A rotatable lead screw 205 is arranged in the water tank 101. The lead screw 205 is screwed with the connecting seat 204. A handwheel 206 is arranged at the end of the lead screw 205, and the handwheel 206 is located outside the water tank 101.

[0035] ​When cooling cable sheaths 104 of different sizes or materials, the handwheel 206 can be rotated to drive the lead screw 205 to rotate. During the rotation of the lead screw 205, the connecting seat 204 can be driven to slide along its axis. A guide sleeve 202 is provided on the mounting seat 201, and a guide rod 203 is provided in the water tank 101. The guide sleeve 202 is slidably sleeved on the guide rod 203 along the axis of the guide rod 203. The cooperation between the guide rod 203 and the guide sleeve 202 is used to guide the movement of the connecting seat 204, so as to control the connecting seat 204 to slide along the axis of the lead screw 205, so as to adjust the distance between the third guide wheel 304 and the second guide wheel 103, so that the inclination angle of the cable sheath 104 extending obliquely downward into the water tank 101 changes, so as to adjust the contact time between the cable sheath 104 and the cooling water when the cable sheath 104 moves for the same time, so as to adjust the cooling time to adapt to the cooling of cable sheaths 104 of different sizes and materials.

[0036] As Figure 4 shown, in this embodiment, when the cable sheath 104 moves, it can drive the third guide wheel 304 to rotate on the mounting wheel 301, and the mounting wheel 301 can be rotated along its hinge point with the mounting seat 201 to adjust the inclination angle of the third guide wheel 304, so that the third guide wheel 304 can be parallel to the inclination direction of the cable sheath 104, reducing the wear of the cable sheath 104 during transportation.

[0037] Multiple groups of rotatable balls 303 are embedded inside the mounting wheel 301, and a guide groove 302 is formed on the third guide wheel 304. The balls 303 are clamped in the guide groove 302. The friction during the rotation of the third guide wheel 304 can be reduced by the arrangement of the balls 303, and further reduce the wear of the cable sheath 104 during transportation.

[0038] The specific usage method and beneficial effects of the present utility model:

[0039] When in use, the cable sheath 104 is guided into the water tank 101 through a set of the first guide wheels 102 and the second guide wheels 103, and extends out of the water tank 101 through the guidance of another set of the first guide wheels 102 and the second guide wheels 103. Cooling water is added into the water tank 101 to cool the cable sheath 104. The cable sheath 104 is driven to move by an external wire winding mechanism, and the cable sheath 104 can be guided out of the next-stage cooling device through the first guide wheel 102 to achieve multi-stage cooling of the cable sheath 104. During the cooling process of cable sheaths 104 made of different materials or with different sizes, the connecting seat 204 can be driven to move along the axis of the guide rod 203 by rotating the lead screw 205, thereby adjusting the distance between the third guide wheel 304 and the second guide wheel 103, so that the length of the cable sheath 104 in contact with the cooling water during movement changes, and the cooling time is adjusted, effectively cooling various cable sheaths 104 with different sizes and materials, and improving the application range of the device.

[0040] The foregoing shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments.
