Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a spraying device for the production and manufacturing of power cables that is easy to clean. Background Technology

[0002] Cables, also known as insulated cables, are generally an assembly consisting of the following parts: one or more insulated cores, and their respective sheaths, overall protective layer, and outer sheath. To prevent corrosion caused by long-term exposure of the cable and its service life, special equipment is used to perform anti-corrosion treatment on the cable, such as spraying the surface of the cable.

[0003] A search revealed that Chinese Patent Publication No. CN222306118U discloses a spraying device for easy cleaning in the production and manufacturing of power cables. The device includes a housing and a cable body disposed on one side thereon. A cavity is provided on the inner side of the housing near the bottom. A first hollow groove is provided on the inner side of the housing near the top and communicates with the left and right outer walls. Multiple connecting pipes communicating with the first hollow groove are fixedly inserted into the inner top of the cavity. A square frame is slidably connected to the inner side wall of the cavity. The square frame is located below the connecting pipes. A purification filter plate is fixedly embedded in the square frame. A pair of support rods are slidably inserted into the front of the square frame. One end of the support rods passes through the square frame and is fixed to the inner side wall of the cavity. An opening corresponding to the square frame is provided on the front of the housing.

[0004] While the above solution has the advantage of facilitating the replacement of the purification filter plate, the outer surface of the cable was not cleaned before spraying, resulting in impurities adhering to the outer surface of the cable during spraying, which affected the spraying effect.

[0005] Therefore, there is an urgent need to provide a spraying device for the production and manufacturing of power cables that is easy to clean, in order to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, which does not clean the outer surface of the cable before spraying, resulting in impurities adhering to the outer surface of the cable during spraying affecting the spraying effect. This utility model provides a spraying device for power cable manufacturing that is easy to clean.

[0007] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a spraying device for manufacturing power cables that is easy to clean is provided, including a base, a spraying device installed on one side edge of the top of the base, and a filter device set on the top of the spraying device. A cleaning component and a drying component are arranged side by side on the top of the base.

[0008] The cleaning assembly includes a fixed base mounted on the top surface of the base, an annular cylinder mounted inside the fixed base, a cleaning component disposed on the side wall of the annular cylinder, and a squeezing unit disposed on the outside of the cleaning component.

[0009] The drying assembly includes a drying chamber installed between the fixed base and the spraying device, and a drying unit located inside the drying chamber.

[0010] The present invention is further configured such that a through hole is provided in the middle of the fixing base.

[0011] The present invention is further configured such that: the number of the cleaning components is multiple sets, and the multiple sets of the cleaning components are distributed in a circular array with the center point of the annular cylinder as the center;

[0012] The cleaning component includes a movable rod movably connected to the inner and outer rings of the annular cylinder, an arc-shaped plate installed at one end of the movable rod, and a cleaning pad disposed on the inner surface of the arc-shaped plate. The other end of the movable rod is provided with a first oblique cut surface.

[0013] The cleaning component also includes a limiting ring installed on the outside of the movable rod and a reset component disposed on the side of the limiting ring.

[0014] The present invention is further configured such that: the inner and outer rings of the annular cylinder are provided with corresponding through holes on their side walls, and a sealing ring is provided at the through hole.

[0015] The present invention is further configured such that: the extrusion unit includes a threaded groove disposed on the side wall of the fixed seat and a ring body threadedly connected inside the threaded groove, wherein a second oblique surface is provided at the inner edge of the ring body, and the size of the second oblique surface is adapted to the size of the first oblique surface.

[0016] The present invention is further configured such that: the cleaning component also includes a water supply pipe installed at the top of the annular cylinder sidewall and a drain pipe disposed at the bottom of the annular cylinder sidewall.

[0017] The present invention is further configured such that: the inner ring sidewall of the annular cylinder is provided with spray holes, and the sidewall of the arc-shaped plate is provided with a circular hole.

[0018] The present invention is further configured such that: the drying unit includes an air-gathering pipe installed at the top of the inner wall of the drying chamber and an annular pipe installed at the bottom of the air-gathering pipe, the annular pipe being connected to the air-gathering pipe, and a nozzle being installed on the wall of the annular pipe.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses a cleaning component to insert the cable to be sprayed through the perforation and then through the spraying device. The operator then rotates the ring body along the threaded groove. When the ring body rotates, it abuts against one end of the movable rod and, with the cooperation of the second and first inclined surfaces, squeezes the movable rod into the annular cylinder. When the movable rod moves, it simultaneously pushes the arc plate and the cleaning pad, so that the cleaning pad comes into contact with the outer surface of the cable. Then, an external water pipe is connected to a water supply pipe, and water enters the annular cylinder through the water supply pipe. The cleaning pad is then wetted by the spray holes and round holes, thereby cleaning the outer surface of the cable. The elasticity of the limiting ring and the reset component prevents excessive squeezing force from damaging the outer surface of the cable.

[0021] 2. This utility model, through its drying component, allows the cable to be moved into the drying chamber after the outer surface of the cable has been cleaned. The external hot air pipe is connected to the concentrator pipe, and the hot air enters the interior of multiple annular pipes through the concentrator pipe. It then works with the nozzles to spray the hot air onto the outer surface of the cable, thereby drying the outer surface of the cable and improving the coating effect. Attached Figure Description
