Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and particularly relates to a cable core coating and forming device for cable processing. Background Art

[0002] Cable core coating refers to the process of covering the cable core with an insulating layer or other protective layers during the cable manufacturing process. The prepared wire core is passed through an extruder, and the insulating layer is wrapped around the conductive wire core. The coating processes include extrusion coating, longitudinal wrapping, winding, dipping, etc., and the materials used can be rubber, plastic, lead, aluminum, etc. Through these steps, the cable core is wrapped in the insulating layer or other protective layers to achieve functions such as electrical insulation and mechanical protection.

[0003] When coating the cable core, when there are impurities on the surface of the cable core, it will damage the tight combination between the insulating layer and the cable core, resulting in delamination between the cable core and the insulating layer, forming pores or local weak points, reducing the insulation strength and withstand voltage ability, increasing the risk of leakage or breakdown. The existing treatment methods are to clean through a cleaning cloth or a dust collector. Since the cable core is generally coated in a large roll, long-term cleaning with a cleaning cloth will cause surface contamination and requires frequent shutdowns to replace the cleaning cloth, otherwise it will cause secondary contamination of the cable core, greatly reducing the coating efficiency. When cleaning with a dust collector, since the cable core is circular, when the dust collector works, the dust collector needs to move in a circular motion around the cable core to ensure comprehensive dust removal of the cable core, or multiple dust collectors are set, increasing the use of the structure and the input cost.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] See also Figures 1-6 The present embodiment provides a cable core coating molding device for cable processing, comprising a coating mechanism 1 and a cooling mechanism 2 arranged downstream of the coating mechanism 1, and also comprising a wiping member 3 arranged upstream of the coating mechanism 1, wherein two wiping members 3 are provided, and the wiping members 3 have a restoring ability, and a coating channel for coating the cable core is formed between the two wiping members 3, and the cable core passes through the channel;

[0038] It also includes a plurality of groups of buffer members, which act on the wiping members 3 so that the two wiping members 3 completely cover the cable core.

[0039] In the embodiment further provided by the present invention, a cleaning pipe 6 is also included, the water inlet of the cleaning pipe 6 is connected to the cooling mechanism 2, two water outlets 61 are arranged on the cleaning pipe 6, the two water outlets 61 are respectively located above the two wiping members 3, the cleaning pipe 6 is connected to a water pump, the water in the cooling mechanism 2 is introduced into the two wiping members 3 through the cleaning pipe 6, the contaminated wiping members 3 after cleaning are cleaned, and the contaminated sponge is prevented from rotating to the cable core to cause secondary contamination.

[0040] Furthermore, the cleaning pipe 6 is wound around the outside of the coating mechanism 1. When the coating mechanism 1 is working, the heat of the coating mechanism 1 is dissipated through the water in the water pipe, and the coating mechanism 1 is cooled to avoid overheating of the molten raw material and decomposition, which affects the strength and appearance quality after extrusion.

[0041] In a further embodiment provided by the present invention, the buffer assembly includes a first crawler belt 31. A plurality of sliding rods 32 are slidably arranged on the first crawler belt 31. The end of the sliding rod 32 is fixedly connected to the wiping member 3. A return spring 33 is sleeved outside the sliding rod 32. When the wiping member 3 contacts the cable core, the return spring 33 pushes the wiping member 3 towards the position of the cable core. The two return springs 33 on both sides enable the two wiping members 3 to completely wrap the cable core, so as to comprehensively clean the surface of the cable core during the movement of the cable core.

[0042] In the embodiment provided by the present invention, an adjusting assembly is further included. The adjusting assembly is used to adjust the positions of the two wiping members 3 so that the two wiping members 3 are in movable abutment with the cable core. The positions of the wiping members 3 are adjusted according to the size of the cable core, so that the wiping members 3 can adapt to cable cores of various sizes, increasing applicability. The adjusting assembly includes a fixing plate 41. Two sliding plates 42 are slidably arranged on the fixing plate 41. The two first crawler belts 31 are respectively arranged on the two sliding plates 42. A bidirectional screw 43 is rotatably connected to the fixing plate 41. The two sliding plates 42 are both threadedly connected to the outside of the bidirectional screw 43.

[0043] In the embodiment provided by the present invention, a water squeezing cylinder 7 fixed to the sliding plate 42 is further included. The water squeezing cylinder 7 is in movable abutment with the wiping member 3. When the wiping member 3 moves to the position of the water squeezing cylinder 7, the water squeezing cylinder 7 will push the sliding rod 32 to move, so that the return spring 33 is compressed, thereby driving the wiping member 3 to deform directly between the water squeezing cylinder 7 and the return spring 33, squeezing out the water after the wiping member 3 is cleaned. An electric heating device is arranged in the water squeezing cylinder 7 to heat the water squeezing cylinder 7, so as to dry the wiping member 3 after the sponge is squeezed dry by the water squeezing cylinder.

[0044] In a further solution provided by the present invention, two rotating assemblies are further included, which are respectively used to drive the two wiping members 3 to rotate so that the rotation direction of the wiping members 3 is opposite to the direction of the cable core, in order to increase the contact area between the cable core and the wiping members 3. By making the movement direction of the wiping members 3 opposite to that of the cable core, the contact area between the cable core and the wiping members 3 during the movement of the cable core is increased, and the cleaning efficiency of the cable core is increased. The rotating assembly includes a plurality of first sprocket shafts 51 rotatably arranged on the sliding plate 42. The first sprocket shaft 51 is a combination of a round rod and a first sprocket. The round rod is rotatably arranged on the sliding plate 42, and the first sprocket is fixed outside the round rod. A same first chain 52 is externally meshed with each first sprocket shaft 51. The first crawler belt 31 is arranged on the first chain 52 and moves synchronously with the first chain 52.

[0045] Further, the rotating assembly further includes a friction roller 53 rotatably arranged on the fixed plate 41. The diameter of the friction roller 53 is adjustable. According to the size of the cable core, the sizes of the two friction rollers 53 are adjusted so that the two friction rollers 53 are in movable abutment with the cable core. During the movement of the cable core, the friction roller 53 can be driven to rotate, and the two friction rollers 53 clamp the cable core so that the cable core is in the central position when moving into the coating mechanism 1, avoiding the offset of the cable core coating, reducing the electric field concentration caused by the coating offset, and reducing the possibility of cable faults. A first gear 54 is fixedly connected to the outside of the friction roller 53. A second gear shaft 55 (similarly to the first sprocket shaft 51) that meshes with the first gear 54 is rotatably connected to the fixed plate 41. Second sprockets 56 are fixedly connected to the outside of both the second gear shaft 55 and any one of the first sprocket shafts 51. The two second sprockets 56 are in transmission engagement through the same second chain 57.

[0046] Specifically, a tensioning wheel 58 is slidably arranged on the fixed plate 41. The tensioning wheel 58 is in transmission engagement with the second sprocket 56. A limiting spring is arranged on the tensioning wheel 58 and abuts against the inner wall of the fixed plate 41. When adjusting the position of the wiping member 3, the sliding plate 42 will be driven to move, causing the positions and distances of the two second sprockets 56 to change. The tensioning wheel 58 is driven to move through the limiting spring so that the two sprockets and the chain are always in a tensioned state.

[0047] In the preferred solution provided by the present invention, a second crawler belt 34 is further included. The second crawler belt 34 is fixed to the inner surface of the wiping member 3 and is fixedly connected to the end of the sliding rod 32. A return spring 33 is arranged between the first crawler belt 31 and the second crawler belt 34, increasing the stability of the movement of the wiping member 3 and ensuring that the wiping member 3 can rebound stably after deformation.

[0048] During use, the cable core is passed through the two wiping members 3, and then sequentially through the coating mechanism 1 and the cooling mechanism 2. The cooling mechanism 2 is provided with flowing water. The two-way screw 43 is rotated to drive the two sliding plates 42 to approach each other, so that the two wiping members 3 approach each other. When the wiping member 3 contacts the cable core, it continues to move, causing the wiping member 3 to deform until the two wiping members 3 completely wrap the cable core. At this time, the sliding rod 32 drives the return spring 33 to deform, and the two friction rollers 53 are arranged to be in movable abutment with the cable core;

[0049] A traction device is provided at the end of the cable core to traction the cable core, causing the cable core to move, driving the rotation of two friction rollers 53, thereby causing the first gear 54 to rotate, driving the synchronous rotation of the second gear shaft 55, and then driving the rotation of the second sprocket 56. The first sprocket shaft 51 is driven to rotate through the second chain 57, so that the rotation of the first sprocket drives the rotation of the first crawler 31, and the wiping member 3 is driven to move in the direction opposite to the movement of the cable core along the surface of the cable core through the sliding rod 32 to clean the surface of the cable core;

[0050] After cleaning, impurities will be adsorbed on the surface of the wiping member 3. Then, the water in the cooling mechanism 2 is flowed through the cleaning pipe 6 to the water outlet 61 by a water pump, and flows through the two water outlets 61 to the two wiping members 3 to clean the wiping members 3. At the same time, the water flow in the cleaning pipe 6 will pass through the coating mechanism 1 to dissipate heat from the coating mechanism 1;

[0051] The cleaned wiping member 3 will continue to move through the water squeezing cylinder 7, causing the wiping member 3 to deform. Through the elasticity of the return spring 33, the wiping member 3 is pushed to be extruded on the surface of the water squeezing cylinder 7 to squeeze out the excess water in the wiping member 3. Then, the wiping member 3 passing through is heated by the electric heat provided in the water squeezing cylinder 7 to dry the cleaned wiping member 3. Then, the cleaned sponge rotates to contact the cable core to clean the cable core again, and the above operations are repeated.

[0052] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
