Description

Technical Field

[0001] The present application relates to the field of cable processing, and in particular to a talc powder coating device for a cable core. Background Art

[0002] During the processing and manufacturing of cables, a layer of PVC insulating sheath needs to be wrapped around the cable core. Adhesion is likely to occur between the core and the insulating sheath, which affects the subsequent processing of the cable and makes cable stripping difficult.

[0003] To address these issues, cable core talc powder coating devices have emerged on the market. These devices coat the cable core surface with talc powder to prevent sticking. However, existing cable core talc powder coating devices only serve to coat the cable core with talc powder. The talc powder easily clumps, resulting in uneven or insufficient coating on the cable core, which affects the coating effect. Summary of the Invention

[0004] In order to improve the coating effect of cable cores, the present application provides a talc powder coating device for cable cores.

[0005] The present application provides a talcum powder coating device for cable cores, which adopts the following technical solution: A talcum powder coating device for a cable core comprises a accommodating chamber and a stirring mechanism. The accommodating chamber is used to stack talcum powder. The stirring mechanism comprises a stirring drive source, a stirring shaft and a stirring rod arranged on the stirring shaft. The stirring drive source is used to drive the stirring shaft to rotate in the accommodating chamber.

[0006] By adopting the above technical solution, the stirring mechanism drives the stirring shaft and the stirring rod to rotate continuously, effectively breaking up the lumps of talcum powder and maintaining the fluidity of talcum powder, thereby ensuring the uniformity and sufficiency of the coating and improving the anti-adhesion effect of the cable core.

[0007] Optionally, it also includes a recovery chamber, a recovery channel and a collection box, the accommodating chamber and the recovery chamber are arranged along the conveying direction of the cable core, a recovery port is opened on the bottom wall of the recovery chamber, the recovery port is connected to the recovery channel, and the recovery channel is used to transport talcum powder to the collection box.

[0008] By adopting the above technical solution, the rapid rotation of the stirring shaft and the stirring rod may cause talcum powder to splash, and at the same time, the cable core will bring out some talcum powder when passing through the accommodating cavity. The recovery cavity can collect the talcum powder that splashes or is brought out by the cable core. The cooperation of the recovery cavity, the recovery channel and the collection box realizes the recovery and recycling of talcum powder, reduces the waste of talcum powder, reduces production costs, and avoids the accumulation of talcum powder to pollute the working environment.

[0009] Optionally, it further includes a temperature controller and a heating plate, wherein the temperature controller is electrically connected to the heating plate, and the heating plate is arranged on the cavity wall of the accommodating cavity.

[0010] By adopting the above technical solution, the thermostat and the heating plate control the temperature in the accommodation cavity to prevent the talcum powder from agglomerating due to moisture or low temperature, ensuring that the talcum powder is always in a dry and loose state, and further optimizing the coating uniformity.

[0011] Optionally, a separation rod is further included, and the separation rod is arranged between adjacent cable cores.

[0012] By adopting the above technical solution, the separator rods physically isolate adjacent cable cores to prevent the cores from contacting or entangled with each other during the coating process, ensuring that the surface of each core can fully contact the talcum powder, thereby improving coating efficiency and consistency.

[0013] Optionally, a conveying mechanism is further included, which is arranged in the accommodating chamber. The conveying mechanism includes a conveying shaft and a spiral blade arranged on the conveying shaft. The conveying shaft is rotatably arranged in the accommodating chamber, and the rotation axis of the conveying shaft extends along the height direction of the accommodating chamber. The spiral blade spirally extends from the bottom of the accommodating chamber to the top of the accommodating chamber around the rotation direction of the conveying shaft.

[0014] By adopting the above technical solution, the spiral blades of the conveying mechanism rotate with the conveying shaft, realizing vertical conveying of talcum powder from bottom to top, forming a circular flow, enhancing the uniformity of talcum powder distribution, preventing local accumulation or shortage, and improving the stirring effect of the stirring shaft and stirring rod.

[0015] Optionally, the conveying mechanism also includes a guide plate, and the conveying shaft, guide plate and stirring shaft are arranged along the conveying direction of the cable core. The guide plate includes an inclined guide portion, and the distance between the guide portion and the bottom wall of the accommodating cavity decreases along the arrangement direction of the conveying shaft and the guide plate.

[0016] By adopting the above technical solution, the inclined guide part of the guide plate is used to receive the talc powder delivered to the top of the accommodating chamber by the conveying shaft, and then guide the talc powder to the vicinity of the stirring shaft so that the talc powder is fully stirred. The guide plate guides the talc powder to flow in a specific direction, reducing the retention area of talc powder near the conveying shaft, optimizing the flow path, and improving the conveying efficiency. The guide plate can isolate the conveying shaft and the stirring shaft to prevent the talc powder stirred by the stirring rod from affecting the loose talc powder on the spiral blade.

[0017] Optionally, the conveying mechanism also includes a guide groove opened on the bottom wall of the accommodating cavity, the distance between the groove side wall of the guide groove and the conveying shaft decreases in the direction approaching the groove bottom wall of the guide groove, and the conveying shaft is rotatably set on the groove bottom wall of the guide groove.

[0018] By adopting the above technical solution, the guide groove can guide the talcum powder falling from the guide plate to the conveying shaft area, enhance the conveying capacity of the spiral blade, and at the same time reduce the residual talcum powder in the stirring shaft area, thereby improving the recovery rate.

[0019] Optionally, the guide plate further includes a bearing portion, which is located on a side of the guide plate away from the bottom wall of the accommodating cavity, and extends along the arrangement direction of the guide plate and the conveying axis.

[0020] By adopting the above technical solution, the bearing part of the guide plate receives the talcum powder delivered to the top of the accommodating cavity by the conveying shaft, and allows the talcum powder to accumulate on the bearing part until the talcum powder is so much that it falls along the guide plate, thereby increasing the powder coating area of the cable core without affecting the fluidity of the talcum powder, and further improving the uniformity and sufficiency of the coating.

[0021] Optionally, a screen is provided in the recovery chamber, and a guide plate is provided at an angle on one side of the screen close to the bottom wall of the recovery chamber, and the guide plate is used to guide the talcum powder into the recovery port.

[0022] By adopting the above technical solution, the screen filters the agglomerates in the recovery chamber, and the guide plate accurately guides the qualified talc powder to the recovery port, thereby realizing the graded recovery of talc powder and ensuring the quality and reuse effect of the recovered talc powder.

[0023] Optionally, it also includes a partition, a driving source and a push plate, the partition is used to separate the accommodating chamber and the recovery chamber, the partition is provided with a connecting hole connecting the accommodating chamber and the recovery chamber, the push plate is slidably arranged on the screen along the arrangement direction of the recovery chamber and the accommodating chamber, the driving source is used to drive the push plate to push the talcum powder into the connecting hole, and the stirring shaft is arranged close to the recovery chamber.

[0024] By adopting the above technical solution, the driving source drives the push plate to push the agglomerated talcum powder on the screen to the connecting hole, so that the talcum powder enters the accommodating cavity through the connecting hole and enters the stirring shaft area, and is stirred by the stirring rod, thereby improving the stirring efficiency and automatically completing the talcum powder recovery, reducing manual intervention, improving the recovery efficiency, and avoiding the problem of screen clogging.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By driving the stirring shaft and stirring rod to rotate continuously, the talcum powder lumps are broken, thereby ensuring the uniformity and sufficiency of the coating and improving the anti-adhesion effect of the cable core; 2.

The stirring mechanism 2 includes a stirring drive source 21, a stirring shaft 22, and a stirring rod 23 fixedly mounted on the stirring shaft 22. The stirring drive source 21 is fixedly mounted on the outer wall of the frame 160, and the stirring shaft 22 is rotatably mounted on the inner wall of the frame 160, and the rotation axis of the stirring shaft 22 extends along the width direction of the frame 160. The stirring drive source 21 is used to drive the stirring shaft 22 to rotate.

[0034] In this embodiment, the stirring drive source 21 is a motor. In other embodiments, any driving method that can drive the stirring shaft 22 to rotate can be used. In this embodiment, the stirring shaft 22 is made of stainless steel, which has good corrosion resistance and strength and can adapt to long-term operation.

[0035] Reference Figure 1 and Figure 2 The cable core talc powder coating device also includes a recovery chamber 3, a recovery channel 4 and a collection box 5. The accommodating chamber 1 and the recovery chamber 3 are arranged along the conveying direction of the cable core, and the stirring shaft 22 is located in the accommodating chamber 1 near the recovery chamber 3. A partition 120 is fixedly installed in the frame 160, and the partition 120 is used to separate the accommodating chamber 1 and the recovery chamber 3. A recovery port 31 is provided on the bottom wall of the recovery chamber 3, and the recovery port 31 is connected to the inlet of the recovery channel 4. The outlet of the recovery channel 4 is connected to the inlet of the collection box 5. The collection box 5 is located below the frame 160, and the recovery channel 4 is used to transport the talc powder in the recovery chamber 3 to the collection box 5.

[0036] Reference Figure 1 The cable core talcum powder coating device also includes a thermostat 6 and a heating plate 7. The thermostat 6 is fixedly mounted on the outer wall of the frame 160, and the heating plate 7 is fixedly mounted on the bottom wall of the accommodating chamber 1. The thermostat 6 is electrically connected to the heating plate 7. The thermostat 6 is used to control the temperature and opening and closing of the heating plate 7. The heating plate 7 can adopt a resistive or ceramic design, which has the characteristics of rapid heating and uniform heat dissipation. The surface of the heating plate 7 is covered with an insulating layer, such as a ceramic coating or a glass fiber layer, to prevent heat from being lost to the outside.

A plurality of separator rods 8 are provided, and the plurality of separator rods 8 are arranged along the width of the frame 160. Each separator rod 8 is located between two adjacent cable cores, thereby separating the adjacent cable cores.

[0038] The implementation principle of a talcum powder coating device for a cable core in an embodiment of the present application is as follows: when the cable core passes over the accommodating chamber 1 while moving, part of the cable core above the accommodating chamber 1 is immersed in the talcum powder in the accommodating chamber 1, and the talcum powder coats the cable core; at the same time, the stirring drive source 21 drives the stirring shaft 22 to rotate, and the stirring shaft 22 drives the stirring rod 23 to rotate, thereby stirring the talcum powder in the accommodating chamber 1 to prevent the talcum powder from agglomerating. Under the stirring of the stirring rod 23, part of the talcum powder will separate from the accommodating chamber 1 and enter the recovery chamber 3. The talcum powder enters the recovery channel 4 through the recovery port 31 and is finally collected in the collection box 5. When a certain amount of talcum powder is accumulated in the collection box 5, the operator pours the talcum powder in the collection box 5 back into the accommodating chamber 1; at the same time, the thermostat 6 controls the operation of the heating plate 7 and adjusts the temperature of the heating plate 7 to heat and dehumidify the talcum powder.

[0039] In this embodiment, a stirring mechanism 2 is provided to stir the talcum powder in the accommodating chamber 1 to break up the lumps of talcum powder, and the talcum powder is heated and dehumidified in cooperation with the temperature controller 6 and the heating plate 7 to prevent the talcum powder from agglomerating due to moisture or low temperature, ensuring that the talcum powder is always in a dry and loose state, thereby ensuring the uniformity and sufficiency of the coating and improving the anti-adhesion effect of the cable core. In addition, by providing a recovery chamber 3, the recovery and recycling of talcum powder can be realized, thereby reducing the waste of talcum powder, reducing production costs, and avoiding the accumulation of talcum powder to pollute the working environment.
