Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, and in particular to a cooling and shaping device for a wide temperature range cable sheath extruder. Background Technology

[0002] In the field of industrial automation, cables used to connect various devices and sensors need to have high-precision dimensions and good physical properties. Cooling and shaping devices can ensure the quality of cable sheaths, enabling cables to operate reliably in harsh industrial environments.

[0003] A search revealed Chinese publication number CN218384618U, which discloses a cooling device for sheathed cable production. The device includes a water tank, with a water reservoir fixedly connected to one side of the bottom. One side of the top of the water reservoir is fixedly connected to the water tank, and an inlet is located on the other side of the top of the water reservoir. An inlet is located at the bottom of the water tank near the water reservoir, and a notch is located at the top of the water tank near the water reservoir. The width of the notch and the diameter of the inlet are both smaller than the width of the inlet. A rectangular opening is located at one side of the bottom of the water tank, and a fixing box is fixedly connected to the rectangular opening. A semiconductor cooling chip is located inside the fixing box. A water pump is fixedly connected to the other side of the bottom of the water tank, and a water pipe is fixedly connected to the outlet of the water pump. This invention cools the sheathed cable in this way, allowing it to enter the coolant directly in a horizontal state. Therefore, no external force is applied to the incompletely cooled sheathed cable, ensuring that the outer sheath of the cable will not deform due to external force.

[0004] The patent description mentions that "a water pipe is fixedly connected to the outlet of the water pump". The backflow of water will cause the cooling water flow rate and flow rate to be unstable, resulting in uneven cooling of the cable sheath. This will cause temperature differences in different parts of the cable sheath, affecting the consistency of its physical properties. For example, excessively high local temperatures will cause inconsistent crystallinity of the sheath material, resulting in a decrease in the mechanical strength, wear resistance and other properties of the cable sheath. In response to the above problems, a cooling and shaping device for a wide temperature range cable sheath extruder is proposed. Utility Model Content

[0005] The cooling and shaping device for a wide-temperature-range cable sheath extruder proposed in this utility model aims to improve the problem that some existing cooling and shaping devices for wide-temperature-range cable sheath extruders cannot prevent water backflow.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cooling and shaping device for a wide-temperature-range cable sheath extruder includes a through-hole placement platform, a cooling box fixedly connected to the top of the through-hole placement platform, a cooling water tank fixedly connected to the outer left side of the through-hole placement platform, a pump body fixedly connected to the top of the cooling water tank, an output pipe fixedly connected to the output end of the pump body, an anti-backflow mechanism fixedly connected to the other end of the output pipe, and a reciprocating mechanism fixedly connected to the top of the cooling box.

[0008] The anti-backflow mechanism includes an anti-backflow housing, which is fixedly connected to the outer top of the output pipe. A cross-shaped placement plate is fixedly connected to the inner bottom of the anti-backflow housing. A placement housing is fixedly connected to the top of the cross-shaped placement plate. A sliding rod is slidably connected inside the placement housing. A return spring is sleeved on the outside of the sliding rod. A sealing plate is fixedly connected to the top of the sliding rod. A cooling circulation assembly is fixedly connected to the bottom of the anti-backflow housing.

[0009] The above solution utilizes a through-hole platform to support the cable, a cooling box for cooling, a cooling water tank and pump for water supply, and an anti-backflow mechanism. Inside the anti-backflow housing, a cross-shaped placement plate supports the housing, and a sliding rod, a return spring, and a sealing plate work together to prevent water backflow. The cooling circulation assembly ensures continuous water circulation, guaranteeing efficient and stable cable cooling and shaping.

[0010] As a further description of the above technical solution:

[0011] The cooling circulation assembly includes a return pipe, which is externally fixedly connected to the bottom of the anti-backflow housing. A return pump is externally fixedly connected to the return pipe, and a return box is externally fixedly connected to the return pump.

[0012] The above solution involves connecting one end of the return pipe to the bottom of the anti-backflow housing to promptly recover the cooled water. The return pump installed on the pipeline provides power to ensure a stable water flow to the return box. Through this circulation system, the cooling water can be reused, ensuring cooling efficiency, effectively saving water resources, and reducing equipment operating costs.

[0013] As a further description of the above technical solution:

[0014] A sealing ring is fixedly connected to the inner top of the anti-backflow housing, and the outer side of the sealing plate is in contact with the outer side of the sealing ring.

[0015] The above solution utilizes a sealing ring at the top of the anti-backflow housing, which is a key component for preventing backflow. It fits tightly with the sealing plate to form a tight seal. When water flows through, the sealing plate comes into close contact with the sealing ring under water pressure, effectively preventing the water from flowing backward and ensuring that the cooling water is delivered unidirectionally to the cooling tank, thus guaranteeing the stable operation of the cooling system.

[0016] As a further description of the above technical solution:

[0017] The reciprocating mechanism includes a mounting plate, which is externally fixedly connected to the top of the cooling box. A dual-head motor is fixedly connected inside the mounting plate. A drive rod is fixedly connected to the drive end of the dual-head motor. An eccentric wheel is fixedly connected to the outside of the drive rod. A rotating plate is rotatably connected to the outside of the eccentric wheel. A sliding plate is rotatably connected to the bottom of the rotating plate. A connecting plate is fixedly connected to the bottom of the sliding plate. A cooling fan is fixedly connected to the outside of the connecting plate.

[0018] The above solution involves a dual-head motor driving a drive rod to rotate on a mounting plate on top of the cooling box. This rotation of the drive rod causes the eccentric wheel to rotate, and the rotating plate causes the sliding plate to reciprocate. The connecting plate at the bottom of the sliding plate is connected to the cooling fan, allowing the cooling fan to move back and forth, expanding the cooling range and cooling the cables more efficiently.

[0019] As a further description of the above technical solution:

[0020] Limiting rods are fixedly connected to both the front and rear sides of the cooling box, and the internal cooling fan is slidably connected to the outside of the limiting rods.

[0021] With the above solution, the limiting rods on the front and rear sides of the cooling box play a key role. When the cooling fan moves back and forth under the drive of the reciprocating mechanism, its interior can slide flexibly outside the limiting rods. The limiting rods provide precise guidance for the movement of the cooling fan, ensuring that the cooling fan moves stably and orderly, thereby enabling more accurate and efficient cooling of the cables inside the cooling box.

[0022] As a further description of the above technical solution:

[0023] Dustproof shells are fixedly connected to both the front and rear sides of the cooling box, and the external side of the connecting plate is slidably connected to the inside of the dustproof shells.

[0024] The above solution provides an indispensable protective casing on the front and rear sides of the cooling box. It encloses the connecting plate and effectively prevents dust, debris, and other impurities from entering the cooling box and transmission structure when the connecting plate slides with the cooling fan under the drive of the reciprocating mechanism. This avoids affecting the cooling effect and equipment operation, ensuring the long-term stable and efficient operation of the cooling system.

[0025] As a further description of the above technical solution:

[0026] The top four corners of the through-hole placement platform are fixedly connected with guide wheels, the left and right sides of the outside of the cooling box are fixedly connected with placement curtains, the outside of the output pipe is fixedly connected with multiple diverter blocks, and the bottom of the diverter blocks is fixedly connected with atomizing nozzles.

[0027] The above solution utilizes guide wheels at the four corners of the platform top to provide smooth guidance for cable transport and reduce friction. Curtains on both sides of the cooling box provide both dust protection and heat preservation, optimizing the cooling environment. The cleverly designed diverter and atomizing nozzles on the output pipe can evenly distribute and atomize the cooling water, increasing the contact area with the cable, improving cooling efficiency, and enabling the cable to quickly set after extrusion, ensuring the production quality of wide-temperature-range cable sheaths.

[0028] As a further description of the above technical solution:

[0029] One end of the reset spring is fixedly connected to the outer bottom end of the sealing plate, and the other end of the reset spring is fixedly connected to the top of the housing.

[0030] The key to the above solution lies in the function of the return spring. One end is securely connected to the bottom of the outer side of the sealing plate, and the other end is tightly fixed to the top of the housing. When there is a positive water flow impact, the sealing plate moves upward and compresses the spring. When the water flow stops or reverses, the spring releases its elastic potential energy to push the sealing plate back to its original position, fitting against the sealing ring and effectively preventing water backflow.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, by activating the pump body, the pump body can draw water from inside the cooling water tank into the diverter block, which then atomizes and sprays the cooling water through the atomizing nozzle. The water then enters the anti-backflow housing through the output pipe, allowing the cooling water to press against the sealing plate. The sealing plate slides inside the housing via the sliding rod, which in turn presses against the return spring, causing the return spring to deform. This allows the water to flow through the cross-shaped placement plate into the return pipe, which then enters the return box through the return pump. When the atomizing nozzle sprays water, the water flows through the through-hole placement platform and falls into the return box, thus entering the cooling water tank.

[0033] 2. In this utility model, by starting the dual-head motor, the dual-head motor can drive the drive rod to rotate. Under the action of the drive rod, the drive rod can drive the rotating plate to rotate through the eccentric wheel. Under the action of the rotating plate, the rotating plate can slide up and down through the sliding plate. Then, the sliding plate can drive the cooling fan to slide outside the cooling box through the connecting plate. Because of the limit rod, the cooling fan will not fall off during the sliding process. Attached Figure Description

[0040] 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.

[0041] Reference Figures 1 to 2This utility model provides an embodiment of a cooling and shaping device for a wide-temperature-range cable sheath extruder, comprising a through-hole placement platform 1. The through-hole placement platform 1 facilitates air circulation and drainage, preventing water accumulation from damaging the device. A cooling box 2 is fixedly connected to the top of the through-hole placement platform 1. The cooling box 2 has a cooling channel and a spray device inside for cooling the cable sheath. The size of the cooling box 2 is adapted to the through-hole placement platform 1, and its height is determined according to the cable production process and cooling requirements. A cooling water tank 3 is fixedly connected to the left side of the through-hole placement platform 1. The surface of the water tank has a liquid level observation window for easy observation of the water level in the tank, for periodic drainage and cleaning. A pump body 4 is fixedly connected to the top of the cooling water tank 3. The inlet of the pump body 4 is connected to the cooling water tank 3 through a pipe to ensure that the cooling water in the tank can be drawn into the pump body 4. An output pipe 5 is fixedly connected to the output end of the pump body 4. The pipe diameter is selected according to the flow rate and head of the pump body 4 to ensure that it can withstand a certain pressure. An anti-backflow mechanism is fixedly connected to the other end of the output pipe 5. 8. The anti-backflow mechanism 8 includes an anti-backflow housing 81, which is cylindrical in shape to ensure its structural strength. The anti-backflow housing 81 is fixedly connected to the top of the output pipe 5. A cross-shaped placement plate 82 is fixedly connected to the bottom of the anti-backflow housing 81. The cross-shaped placement plate 82 provides support and fixation for the placement housing 83. The top of the cross-shaped placement plate 82 is fixedly connected to the placement housing 83. The placement housing 83 has a smooth inner wall to facilitate the sliding of the sliding rod 84. The sliding rod 84 is slidably connected inside the placement housing 83 to reduce friction with the inner wall of the placement housing 83. The sliding rod 84 can slide freely inside the placement housing 83.

[0042] Specifically, the through-hole placement platform 1 facilitates air circulation and drainage. Its top is connected to the cooling box 2. The cooling channel and spray device inside the box cool the cable sheath. The size and height are designed as needed. The cooling water tank 3 on the left side of the through-hole placement platform 1 is equipped with a liquid level observation window for easy monitoring of water level and maintenance and cleaning. The pump body 4 on the top of the water tank draws in cooling water through the pipe and delivers it to the anti-backflow mechanism 8 through the output pipe 5. In this mechanism, the cylindrical anti-backflow housing 81 is fixed to the top of the output pipe 5. The internal cross placement plate 82 supports the placement housing 83. Its smooth inner wall allows the sliding rod 84 to slide freely, preventing the cooling water from flowing back and ensuring the stable operation of the cooling system, providing a reliable guarantee for the cooling and shaping of the cable sheath.

[0043] A return spring 85 is sleeved on the outside of the sliding rod 84. The elastic coefficient of the return spring 85 is designed according to actual working requirements to ensure that it can provide sufficient elastic force during normal operation. A sealing plate 86 is fixedly connected to the top of the sliding rod 84. The surface of the sealing plate 86 is flattened to ensure sealing when it fits with the sealing ring 87. A cooling circulation assembly 88 is fixedly connected to the bottom of the anti-backflow housing 81. The cooling circulation assembly 88 includes a return pipe 8801. The surface of the return pipe 8801 is treated with anti-corrosion measures, such as galvanizing or painting, to prevent the pipe from rusting and corroding. The return pipe 8801 is externally fixedly connected to the bottom of the anti-backflow housing 81. The return pipe 8801 is externally fixedly connected to the return pump 8802. The return pump 8802 is externally fixedly connected to the return tank 8803. The surface of the return tank 8803 is provided with a liquid level observation window, which is convenient for operators to observe the water level in the tank and is used for periodic drainage and cleaning of the water tank. The top of the anti-backflow housing 81 is internally fixedly connected to a sealing ring 87. The function of the sealing ring 87 is to cooperate with the sealing plate 86 to prevent the cooling water from flowing back. The outside of the sealing plate 86 is in contact with the outside of the sealing ring 87.

[0044] Specifically, the sliding rod 84 is fitted with a return spring 85 with an elastic coefficient designed according to actual needs, and a flat-treated sealing plate 86 is fixed at the top. The bottom of the anti-backflow housing 81 is connected to the cooling circulation assembly 88. The return pipe 8801 is corrosion-resistant, with one end connected to the anti-backflow housing 81 and the other end connected to the return pump 8802 and the return box 8803. The return box 8803 is equipped with a liquid level observation window for easy maintenance. The sealing ring 87 at the top of the anti-backflow housing 81 fits against the sealing plate 86. During normal operation, the return spring 85 provides elasticity to keep the sealing plate 86 and the sealing ring 87 in close contact to prevent cooling water backflow. When there is a pressure change that causes the sealing plate 86 to move upward, the cooling water flows into the return box 8803 through the return pipe 8801 under the action of the return pump 8802, realizing cooling circulation.

[0045] Reference Figures 2 to 3A reciprocating mechanism 9 is fixedly connected to the top of the cooling box 2. The reciprocating mechanism 9 includes a mounting plate 91. The surface of the mounting plate 91 is finely machined to ensure the installation accuracy of components such as the dual-head motor 92. The dimensions of the mounting plate 91 are designed according to the dimensions of the dual-head motor 92. The external of the mounting plate 91 is fixedly connected to the top of the cooling box 2, and the internal of the mounting plate 91 is fixedly connected to the dual-head motor 92. The two ends of the drive shaft of the dual-head motor 92 extend out to provide power to the drive rod 93. The speed of the motor can be adjusted by a frequency converter. To meet different cooling requirements, a drive rod 93 is fixedly connected to the drive end of the dual-head motor 92. The connection points between the two ends of the drive rod 93 and the coupling and eccentric wheel 94 are precision machined to ensure concentricity and stability, reducing vibration and noise during operation. An eccentric wheel 94 is fixedly connected to the outside of the drive rod 93. The function of the eccentric wheel 94 is to convert the circular motion of the drive rod 93 into the oscillation of the rotating plate 95. A rotating plate 95 is rotatably connected to the outside of the eccentric wheel 94. One end of the rotating plate 95 is connected to the eccentric wheel 94, and the other end... The rotating plate 95 is rotatably connected to the sliding plate 96 via a pin. Driven by the eccentric wheel 94, the rotating plate 95 oscillates, thereby driving the sliding plate 96 to reciprocate linearly. The bottom of the rotating plate 95 is rotatably connected to the sliding plate 96, ensuring the linearity and stability of the sliding plate 96's movement. A connecting plate 97 is fixedly connected to the bottom of the sliding plate 96. The function of the connecting plate 97 is to transmit the movement of the sliding plate 96 to the cooling fan 98. The dimensions of the connecting plate 97 are designed according to the installation dimensions of the cooling fan 98 to ensure a secure installation of the cooling fan 98. A cooling fan 98 is fixedly connected to the outside of the connecting plate 97. The cooling fan 98 has a sliding sleeve inside, which is slidably connected to the limiting rod 99. Under the constraint of the limiting rod 99, the cooling fan 98 can reciprocate linearly along the limiting rod 99, thereby expanding the cooling range. The front and rear sides of the cooling box 2 are fixedly connected to the limiting rod 99. The function of the limiting rod 99 is to guide and limit the movement of the cooling fan 98, ensuring that the cooling fan 98 can stably reciprocate linearly. The inside of the cooling fan 98 is slidably connected to the outside of the limiting rod 99.

[0046] Specifically, the reciprocating mechanism 9 at the top of the cooling box 2 enables the reciprocating motion of the cooling fan 98 to expand the cooling range. The mounting plate 91 is precision machined to fit the size of the dual-head motor 92 and is fixed to the top of the cooling box 2. The dual-head motor 92 adjusts its speed through a frequency converter. Its two drive shafts power the drive rod 93. The drive rod 93 drives the eccentric wheel 94, converting the circular motion into the oscillation of the rotating plate 95. The rotating plate 95 is connected to the sliding plate 96 through a pin, driving the sliding plate 96 to perform reciprocating linear motion. The sliding plate 96 is connected to the cooling fan 98 through the connecting plate 97. The sliding sleeve inside the cooling fan 98 slides in cooperation with the limiting rods 99 on the front and rear sides of the cooling box 2. Under the guidance and limitation of the limiting rods 99, the cooling fan 98 moves in a straight line, effectively improving the cooling effect of the cable sheath.

[0047] Reference Figures 3 to 4 Dust covers 910 are fixedly connected to the front and rear sides of the cooling box 2. The dust covers 910 can completely cover the sliding area of ​​the connecting plate 97. The outside of the connecting plate 97 is slidably connected to the inside of the dust covers 910. Guide wheels 10 are fixedly connected to the top four corners of the through hole placement platform 1. The guide wheels 10 are used to support and guide the movement path of the cable in the cooling box 2 to prevent the cable from deviating or getting stuck. Placement curtains 11 are fixedly connected to the left and right sides of the cooling box 2. The top of the placement curtains 11 is fixed to the cooling box 2 by aluminum alloy pressure strips and bolts, and the bottom hangs down naturally with the edges... After heat sealing to prevent wear, multiple diverter blocks 6 are fixedly connected to the outside of the output pipe 5. The diverter block 6 has a guide groove inside to ensure uniform distribution of coolant and reduce pressure loss. The bottom of the diverter block 6 is fixedly connected to an atomizing nozzle 7, which can atomize the coolant into fine particles, increase the contact area between the coolant and the cable sheath, and improve cooling efficiency. The installation spacing of the nozzles is determined according to the length of the cooling box 2 and the cable running speed. One end of the return spring 85 is fixedly connected to the bottom of the outer side of the sealing plate 86, and the other end of the return spring 85 is fixedly connected to the top of the housing 83.

[0048] Specifically, the dustproof shells 910 on the front and rear sides of the cooling box 2 cover the sliding area of ​​the connecting plate 97 to prevent dust from entering. The guide wheels 10 at the four corners of the through-hole placement platform 1 support and guide the cable to avoid deviation and jamming. The placement curtains 11 on both sides of the cooling box 2 are fixed at the top and hang down at the bottom, with heat-sealed edges to prevent wear. The diverting block 6 on the output pipe 5 evenly distributes the coolant through the guide groove to reduce pressure loss. The bottom atomizing nozzle 7 atomizes the coolant, increasing the contact area with the cable sheath and improving cooling efficiency. In the anti-backflow mechanism 8, one end of the return spring 85 is connected to the sealing plate 86, and the other end is connected to the placement shell 83. Together with the sealing plate 86 and the sealing ring 87, it prevents the coolant from flowing back. All components work together to ensure the quality and efficiency of the cable sheath cooling and shaping.

[0049] Working principle: By activating the pump body 4, the pump body 4 can cause the water inside the cooling water tank 3 to flow into the diversion block 6. Under the action of the diversion block 6, the diversion block 6 can atomize and spray the cooling water through the atomizing nozzle 7, and then enter the anti-backflow housing 81 through the output pipe 5. The force of the cooling water can squeeze the sealing plate 86, causing the sealing plate 86 to slide inside the housing 83 through the sliding rod 84. Then, the sliding rod 84 can squeeze the return spring 85, causing the return spring 85 to deform. Then, the water flow can enter the return pipe 8801 through the cross placement plate 82, and the return pipe 8801 enters the return box 8803 through the return pump 8802. When the atomizing nozzle 7 sprays water, the water flow falls into the return box 8803 through the through hole placement platform 1, and enters the cooling water tank 3 together.

[0050] When adjusting the cooling fan 98, the dual-head motor 92 is started. Under the action of the dual-head motor 92, the drive rod 93 is rotated. Under the action of the drive rod 93, the drive rod 93 drives the rotating plate 95 to rotate through the eccentric wheel 94. Under the action of the rotating plate 95, the rotating plate 95 slides up and down through the sliding plate 96. Then, the sliding plate 96 drives the cooling fan 98 to slide outside the cooling box 2 through the connecting plate 97. Because of the limit rod 99, the cooling fan 98 will not fall off during the sliding process.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
