Description

Technical Field

[0001] This utility model relates to the field of cable production, and in particular to a surface treatment device for cable production. Background Technology

[0002] During cable manufacturing, the conductor undergoes an extrusion process, where molten plastic raw materials are evenly coated onto the surface of the conductor using an extruder, forming a sheath layer on the cable surface. To improve cable flexibility and facilitate customer wiring or wire harness assembly, plastic raw materials with good flexibility are prioritized during the cable design and development stage to ensure the cable's flexibility requirements are met.

[0003] When the cable sheath material is relatively soft, it can lead to significant surface stickiness, especially under high temperature and humidity conditions. Cable production is typically a continuous, large-scale process, where cables are wound onto large-diameter reels. During winding, the cables on the reel are repeatedly squeezed by the layers of cables, eventually causing them to stick together due to the continuous pressure. This sticking can damage the outer plastic layer of the cable during customer use, rendering it unusable and resulting in losses. To address these problems, we propose a surface treatment device for cable production. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for cable production, which has the advantage of preventing cables from sticking together on turnover reels.

[0006] Using the above technical solution, the barrier agent solution is delivered to the nozzle by a water pump. The nozzle evenly applies the barrier agent solution to the surface of the cable. The barrier agent solution is quickly dried under the high temperature of the cable sheath, leaving the barrier material on the surface of the cable to play a barrier role. This prevents the cable from sticking on the turnover reel, avoids damage to the cable during winding, and improves practicality.

[0007] The present invention is further configured such that: the bottom of the recycling tank is connected to a processing box, and the bottom of the processing box is connected to one end of the return pipe; two filter screens are slidably connected between the inner walls of the processing box; a cover plate is provided on the surface of the processing box; a locking rod is slidably sleeved on the inner wall of the cover plate; a spring is provided between one end of the locking rod and the inner wall of the cover plate; a locking hole is opened on the inner wall of the processing box, and the locking hole is locked with one end of the locking rod; a handle is bolted to the surface of the cover plate; a pull plate is slidably connected between the inner walls of the handle; a pull rod is hinged to both ends of the pull plate, and the other end of the pull rod is hinged to the surface of the locking rod.

[0008] By adopting the above technical solution, the barrier agent solution is filtered through a filter screen to ensure its cleanliness and prevent nozzle clogging. The pull rod is moved by moving the pull plate, which causes the pull rod to disengage from the locking hole. The cover plate is then opened, and the filter screen can be removed for easy maintenance.

[0009] The present invention is further configured such that: the stirring mechanism includes a motor, the motor is bolted to the surface of the return water tank, the output end of the motor extends into the interior of the return water tank and is connected to a rotating shaft via a coupling, and the other end of the rotating shaft is rotatably connected to the inner wall of the return water tank, and a stirring plate is bolted to the surface of the rotating shaft.

[0010] By adopting the above technical solution, a stirring mechanism is set up. The motor rotates, which drives the rotating shaft to rotate. The rotating shaft drives the stirring plate to rotate, which stirs the barrier agent solution, prevents the barrier agent solution from settling, and ensures the quality of the barrier agent solution.

[0011] The present invention is further configured such that a protective shell is bolted to the surface of the return water tank, and the water pump is located inside the protective shell.

[0012] By adopting the above technical solution, a protective shell is installed to protect the water pump.

[0013] The present invention is further configured such that one end of the snap-fit ​​rod is wedge-shaped.

[0014] By adopting the above technical solution, one end of the locking rod is wedge-shaped, which facilitates the installation of the cover plate.

[0015] The present invention is further provided with a sealing gasket between the cover plate and the inner wall of the processing box.

[0016] By adopting the above technical solution, water leakage is prevented by setting a sealing gasket.

[0017] The present invention is further configured such that: a fixing block is bolted to the bottom of the recycling tank, and the fixing block is fixedly sleeved with the surface of the connecting pipe.

[0020] By adopting the above technical solution, guide rods are installed to protect the cables during transport.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model uses a water pump to deliver the barrier agent solution to the nozzle, which then evenly coats the cable surface with the barrier agent solution. The barrier agent solution is rapidly dried under the high temperature of the cable sheath, leaving the barrier material on the cable surface to provide a barrier effect. This prevents the cable from sticking to the reel, avoids damage to the cable during winding, and improves its practicality.

[0023] 2. This utility model filters the barrier agent solution by setting a filter screen, ensuring the cleanliness of the barrier agent solution and avoiding clogging of the nozzle. By moving the pull plate, the pull rod moves the locking rod, causing the locking rod to disengage from the locking hole, opening the cover plate, and removing the filter screen for easy maintenance.

[0040] Brief description of the usage process: The recovery tank 1 is installed at the outlet of the extruder head. When the cable is extruded, it passes through the recovery tank 1. The water pump 3 draws the barrier agent solution from the return water tank 2, and delivers it to the universal pipe 5 through the connecting pipe 4. Then it is sprayed out from the nozzle 7 to coat the surface of the cable. Because the temperature of the freshly extruded cable sheath is high, the barrier agent solution can be dried quickly, leaving the barrier material on the surface of the cable to play a barrier role. The remaining barrier agent solution enters the treatment tank 10 through the recovery tank 1. After being filtered by the filter screen 11, the top filter screen 11 is a coarse filter screen 11, and the bottom filter screen 1... 1. A fine filter screen 11 is circulated into the return water tank 2 through the return pipe 8, thereby preventing cables from sticking to the turnover reel. Move the pull plate 17, which drives the pull rod 18 to move. The pull rod 18 drives the locking rod 13 to move, and the locking rod 13 disengages from the locking hole 15. Remove the cover plate 12, take out the filter screen 11 for maintenance, and after maintenance, put the filter screen 11 into the treatment box 10, cover the cover plate 12, and the locking rod 13 is locked into the locking hole 15 under the action of the spring 14 to fix it, which facilitates the maintenance of the filter screen 11.
