Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable processing, in particular to a wire and cable powder coating device. Background Art

[0002] The manufacture of wires and cables adopts a continuous superposition combined production method, starting with conductor processing, and then superimposing insulation, shielding, cabling, and sheaths on the periphery of the conductor to make wire and cable products. The insulation and sheaths are made by melting the heated hot-melt / thermosetting material through an extrusion die and then coating it on the cable core. This can easily lead to adhesion between the insulation of the cable cores and between the insulation and the sheath. The adhered core and sheath are difficult to separate during subsequent wire cutting and stripping, which can easily lead to tearing of the insulation layer and exposing the copper wire, posing a safety hazard.

[0003] As disclosed in Chinese patent announcement number CN217485161U, a wire and cable powder coating device is used. When in use, two spiral blades with opposite rotation directions are arranged on the rotating shaft, so that when the rotating shaft rotates, the two spiral blades push the talcum powder to move towards each other, thereby forming a powder pile in the middle position of the powder box, which can effectively avoid the talcum powder from overflowing. At the same time, since the force applied by the spiral blade to the talcum powder is oblique, the two spiral blades with opposite rotation directions can fully turn the talcum powder, eliminate the internal agglomeration phenomenon, make the powder pile more fluffy, the talcum powder has better fluidity, and the coating effect of the wire and cable is better. By setting an infiltration box and an infiltration liquid carrier, the wire and cable are first infiltrated in the infiltration box before entering the powder box to apply the talcum powder, so that the surface of the wire and cable is coated with a layer of infiltration liquid, and then enter the powder box to apply the talcum powder, which can greatly improve the bonding force between the talcum powder and the surface of the wire and cable, avoid the talcum powder from falling off the surface of the wire and cable, and further avoid adhesion between the extruded layers of the wire and cable.

[0004] However, in the wire and cable powder coating device in the above application, when the cable adheres to the impregnation liquid and enters the powder box for talcum powder coating, it will cause the talcum powder inside the powder box to become wet and agglomerated. If it is not dried, it will affect the subsequent powder coating. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a kind of wire and cable powder coating device. Utility Model Content

[0006] The purpose of the utility model is to provide a wire and cable powder coating device to solve the problem that when the cable line adheres to the infiltrative liquid and enters the powder box for talcum powder coating, it will cause the talcum powder inside the powder box to become wet and agglomerated. If it is not dried, it will affect the subsequent powder coating.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a powder coating device for wires and cables, comprising a powder coating box and a wetting box, the wetting box being fixedly connected to the left side of the powder coating box, a powder coating device being arranged inside the powder coating box, and a wetting device being arranged inside the wetting box.

[0008] The powder coating device comprises a turning unit, a drying unit and a powder removing unit.

[0009] The flipping unit includes a flipping motor, a sealed bearing, a rotating shaft, and a flipping auger. The flipping motor is installed at the top front end of the powder coating box, and the sealed bearing is installed inside the top front end of the powder coating box. The rotating shaft is connected to the output end of the flipping motor, and its bottom extends into the inner bottom of the powder coating box and is rotatably connected to the inside of the sealed bearing. The flipping auger is fixedly connected to the outer surface of the rotating shaft. Starting the flipping motor drives the rotating shaft to rotate inside the sealed bearing, thereby driving the flipping auger on the outer surface of the rotating shaft to rotate, and flipping the talcum powder at the bottom of the powder coating box to the top.

[0010] A further improvement is that there are two groups of the turning units, which are symmetrically installed on the front and rear sides of the powder coating box, and the two groups of turning augers run synchronously to turn more talcum powder.

[0011] A further improvement is that the drying unit includes a dryer, an air inlet pipe, a drying hood, and a filter. The dryer is installed on the top of the powder coating box, the air inlet pipe is fixedly connected to the air outlet of the dryer, and its bottom extends into the inner top of the powder coating box, the drying hood is fixedly connected to the bottom of the air inlet pipe, and the filter is installed inside the drying hood. When the talcum powder is flipped to the top of the powder coating box, the dryer is started, and the hot air is blown through the air inlet pipe to the drying hood and blown out, thereby drying the wet talcum powder to prevent the talcum powder from condensing into clumps and affecting the powder coating effect. The setting of the filter prevents the talcum powder from entering the interior of the dryer through the air inlet pipe and causing damage to the dryer.

[0012] A further improvement is that the powder removal unit includes a driving motor, a rotating shaft, and a vibration block. The driving motor is installed on the right outer surface of the powder coating box, the rotating shaft is connected to the output end of the driving motor, and its left end extends into the interior of the powder coating box. The vibration block is fixedly connected to the left end of the rotating shaft. Starting the driving motor drives the rotating shaft to rotate, thereby driving the vibration block to rotate. When the vibration block rotates, its outer end slowly hits the cable, causing the cable to vibrate, thereby shaking off excess talcum powder on the surface of the cable.

[0013] A further improvement is that talcum powder is filled inside the powder coating box, an inlet hole is obliquely opened on the left outer surface of the powder coating box, and an outlet hole is opened on the right outer surface of the powder coating box. The oblique inlet hole is higher than the height of the impregnating liquid inside the impregnation box to prevent the impregnating liquid from entering the powder coating box, and the bottom is lower than the talcum powder inside the powder coating box, so that the cable can pass through the talcum powder for powder coating.

[0014] A further improvement is that the infiltration device includes a support frame, an electric lifting rod, a mounting frame, a rotating bearing, and a wire-crimping roller. The support frame is fixedly connected to the top of the infiltration box, the electric lifting rod is installed at the bottom of the support frame, and the mounting frame is fixedly connected to the bottom of the electric lifting rod. The two rotating bearings are installed at the front and rear ends of the mounting frame. The front and rear ends of the wire-crimping roller are respectively rotatably connected to the inside of the rotating bearing. The electric lifting rod is started to push the mounting frame downward, so that the wire-crimping roller moves downward to press the cable into the inner bottom of the infiltration box, so that the cable is fully infiltrated.

[0015] A further improvement is that the interior of the impregnation box is filled with impregnation liquid, and wire threading holes are provided on the left and right outer surfaces of the impregnation box, and the wire threading holes are on the same horizontal line as the wire inlet holes on the powder coating box. The height of the wire threading holes is higher than the height of the impregnation liquid, and the impregnated cable directly passes through the wire threading holes and enters the wire inlet hole on the left side of the powder coating box to enter the powder coating box for powder coating.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. In the wire and cable powder coating device, when the talcum powder is turned to the top of the powder coating box, the dryer is started to blow hot air through the air inlet pipe to the drying hood and blown out, thereby drying the wet talcum powder to prevent the talcum powder from condensing into agglomerates and affecting the powder coating effect. The setting of the filter screen prevents the talcum powder from entering the interior of the dryer through the air inlet pipe and causing damage to the dryer.

[0018] 2. The wire and cable powder coating device starts the driving motor to drive the rotating shaft to rotate, thereby driving the vibration block to rotate. When the vibration block rotates, its outer end slowly hits the cable line, thereby vibrating the cable line, thereby shaking off the excess talcum powder on the surface of the cable line.
