AI Technical Summary
Existing cable materials suffer from uneven heating and insufficient dehumidification during the drying and dehumidification process, especially with excessive drying at the bottom and insufficient drying at the top.
The design employs a spiral guide tube and a pushing assembly. The spiral guide tube causes the cable material to move downwards under gravity, while hot air moves upwards from below. Combined with the pushing action of the pushing assembly, this achieves uniform heating and drying of the cable material.
It improves the heating uniformity and drying and dehumidification effect of cable material, avoids contact between cable material and hot and humid air, and enhances the uniformity and efficiency of drying.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of cable production technology, and specifically relates to a cable processing equipment. Background Technology
[0002] Plastics used for wire and cable insulation and sheathing, commonly known as cable materials, include various types such as rubber, plastics, and nylon, and are the main raw materials for cable production and processing. To improve cable performance, cable materials often contain polar materials, which make them prone to absorbing moisture. During cable extrusion, moisture-absorbing cable materials can cause poor cable appearance and performance degradation. Therefore, cable manufacturers typically dry and dehumidify the cable materials before production.
[0003] There are generally two conventional heating methods for cable materials: one is to use a dryer to dry the cable material, and the other is to use a vibrating elevator to heat the fan. When the dryer dries the cable material, the heat is concentrated in a specific area, resulting in insufficient uniformity in drying. When the vibrating elevator is used for drying, the hot air moves upward from the bottom of the vibrating elevator along with the cable material. After the cable material is heated, the hot and humid gas overflows from the top along with the cable material, resulting in insufficient dehumidification of the cable material.
[0004] To address the aforementioned issues, the applicant previously disclosed a cable production and processing equipment with patent authorization announcement number "CN 110936519 B". This equipment features a hollow screen with an internal air intake channel. The screen is connected to an air intake pipe, and several air outlets are located at the top of the screen to introduce hot air into the screen, which then flows out through the air outlets at the top. This disperses the hot air, allowing it to better contact the cable material and achieve better heating uniformity. However, in actual use, since the cable material is directly piled in the material bin, when hot air rises from the bottom of the bin and comes into contact with the cable material, the upward movement of the hot air results in the bottom air being drier and hotter, while the top air is relatively cooler and contains moisture. This leads to the cable material at the bottom of the bin being overheated while the top material is underheated, resulting in uneven drying and dehumidification. Summary of the Invention
[0005] The present invention aims to provide a cable processing device to improve the uniformity of cable material drying and dehumidification.
[0006] One type of cable processing equipment in this solution includes a hot air blower, a material box, and a lifting pipe fixedly connected inside the material box. A spiral guide pipe is fixedly connected to the lifting pipe. The top of the material box is provided with a feed inlet, and the air outlet of the hot air blower is connected to the lower end of the spiral guide pipe.
[0007] The working principle and beneficial effects of this solution are as follows: When in use, the hot air blower is started, and the cable material is fed into the top of the spiral guide tube from the feed inlet. Under the action of gravity, the cable material moves downward along the spiral guide tube. At the same time, the hot air generated by the hot air blower moves upward from the lower end of the spiral guide tube, so that the cable material in the spiral guide tube transitions from contact with the lower temperature hot air component to the high temperature hot air. This improves the heating uniformity and prevents the cable material from contacting the humid hot air, further improving the drying and dehumidification effect.
[0008] Furthermore, a feeding hopper is provided on the top of the material box, and the feeding hopper is connected to the top of the spiral guide pipe. The feeding hopper facilitates more convenient feeding of cable materials.
[0009] Furthermore, the top of the material box is equipped with an air outlet. The air outlet facilitates the faster escape of hot and humid air.
[0010] Furthermore, a support column is provided inside the material box, and the support column is fixedly connected to the outer wall of the spiral guide tube. The provision of the support column helps to improve the stability of the spiral guide tube.
[0011] Furthermore, the bottom of the spiral guide tube is provided with a leakage hole, and the cable processing equipment also includes a guide block and a pushing assembly. The pushing assembly includes two plastic strips and multiple push plates fixed at intervals between the plastic strips, with ventilation holes evenly distributed on the push plates. The guide block is fixedly connected inside the material box, and a guide hole is provided inside the guide block. Limiting grooves are provided on the guide hole and the inner wall of the spiral guide tube. The plastic strips are slidably connected in the limiting grooves and form a closed loop. A motor is installed on the outer wall of the material box, and a through hole is provided on the wall of the lifting tube for the push plates and plastic strips to pass through. A disc is provided inside the lifting tube, and the disc is fixedly connected to the output shaft of the motor. Push teeth that push the push plates to move are provided at intervals on the outer wall of the disc. Under the upward force of hot air, it is difficult for the cable material to move downward in the spiral guide tube by gravity alone. By setting up an electric guide block, a pushing assembly, a motor, a disc, and pusher teeth, the motor drives the disc to rotate, and the pusher teeth push the pusher plate in the lifting tube to move forward, thereby driving the entire pushing assembly to move. Since the cable material is located between adjacent pusher plates, during the movement of the pushing assembly, the cable material is pushed to the lower end of the spiral guide tube and falls to the bottom of the material box through the leakage hole.
[0012] Furthermore, guide rails are provided on the inner walls of both the guide hole and the spiral guide tube, and a limiting notch is provided on the push plate, with the guide rails located within the limiting notch. The guide rails and limiting grooves further enhance the stability of the push assembly during movement.
[0013] Furthermore, a limiting groove is also provided on the inner wall of the lifting tube. By providing a limiting groove on the inner wall of the lifting tube, the plastic strip is slidably connected within the limiting groove, further improving the stability of the pushing assembly during movement.
[0014] Furthermore, a top cover is detachably connected to the top of the lifting tube, and a guide rail is also provided on the lower surface of the top cover. By providing a guide rail on the top cover, the limiting notch on the push plate cooperates with the guide rail, further improving the stability of the pushing assembly during movement.
