Description

Technical Field

[0001] The invention relates to the technical field of water-blocking cable production, in particular to a novel glue scraping device for water-blocking cables. Background Art

[0002] Water-blocking cable is composed of multiple cores of the same or different structural units twisted together. Filling glue needs to be added between the structural units to achieve the water-blocking performance of the cable. In the process of producing the twisted core of the water-blocking cable, in order to achieve a full appearance of the cable core and ensure the water-blocking performance, it is inevitable that excess filling glue will overflow. The overflowing filling glue adheres to the surface of the cable core after curing, causing cured soft particles of different shapes to appear on the surface, resulting in inconsistent outer diameters of the water-blocking cable, which cannot meet the refined production of subsequent processes.

[0003] To ensure the normal production of water-blocking cables, the overflowed filling glue needs to be removed. At present, this process has been carried out by manual glue scraping. For cables with long lengths, multiple people are required to carry out the glue scraping process. In addition, the appearance quality consistency after removal is poor and the removal efficiency is low. It is easy to miss some points of glue scraping, resulting in the cable appearance not meeting the technical requirements and having to be processed in sections, which seriously affects the normal turnover of the process. In addition, some dust often adheres to the surface of the water-blocking cable after the glue scraping process. For this reason, a new type of glue scraping device for water-blocking cables is proposed, which can realize the rapid scraping of glue on the water-blocking cables and conveniently clean the dust on the surface of the water-blocking cables, effectively reducing the labor intensity of personnel.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-8 , the embodiment of the present invention provides the following technical solutions: Embodiment 1 A novel glue scraper device for water-blocking cables comprises an equipment base 1 and a glue scraper assembly 2 arranged on the equipment base 1. The equipment base 1 is composed of a metal base plate, a support bracket and a metal platform. The metal base plate is made of a steel plate of a certain thickness. Fixing bolts are arranged at the four corners to ensure that the equipment is fixed to the ground stably and firmly. A metal platform is arranged on the support bracket. Large-size bolts are arranged at the four corners. The screws and nuts of the metal platform are adjusted to achieve the function of controlling the center height of the glue scraper assembly 2 to be consistent with the center height of the cable production line.

[0018] As a preferred solution, the scraper assembly 2 includes a rotary drive assembly 4 and a scraper head 5, and the scraper head 5 is fixedly installed on the rotating part of the rotary drive assembly 4 by bolts, wherein the rotary drive assembly 4 is used to drive the scraper head 5 to rotate to ensure that a uniform and comprehensive scraping operation can be performed along the twisting direction of the water-blocking cable. Specifically, the rotary drive assembly 4 includes a servo motor 401 and a step sleeve 402, and the servo motor 401 is electrically connected to an external power supply and controlled by an electrical control switch. It is further explained that the electrical control switch is provided with left turn, off and right turn functions, which can meet the requirements of different twisting directions of water-blocking cable cores, and the speed of the servo motor 401 is controlled by a speed regulator to meet the scraping speed required for cables with different outer diameters. The output end of the servo motor 401 is transmission-connected to the step sleeve 402 through a V-belt transmission member 403, and a fixed plate 404 is sleeved and rotatably installed on the outer periphery of the step sleeve 402, and the fixed plate 404 and the servo motor 401 are both fixedly installed on the top of the equipment base 1.

[0019] As a preferred solution, in order to realize convenient disassembly and assembly of the scraper head 5, an inner hexagonal notch is provided at one end of the stepped sleeve 402, and the scraper head 5 includes a hexagonal plug-in barrel 501, the outer periphery of the hexagonal plug-in barrel 501 is slidably connected to the inner surface of one end of the stepped sleeve 402, and the hexagonal plug-in barrel 501 and the stepped sleeve 402 are fixed by bolts, and a docking ring 502 is fixedly installed at one end of the hexagonal plug-in barrel 501, and three groups of film mold sleeves 503 are embedded and fixedly installed at one end of the docking ring 502, and the three groups of film mold sleeves 503 are evenly spaced. The rubber scraper 504 is connected to the rubber mold sleeve 503 in a circular distribution. The rubber scraper 504 is composed of an engineering plastic sheet with moderate hardness and softness, and its thickness is controlled at 6-10mm. During the rubber wiping process, it is ensured that the hardness of the rubber scraper 504 is sufficient and not deformed. The end of the rubber scraper 504 is designed to be arc-shaped. When contacting the water-blocking cable core, it is ensured that the excess rubber particles are scraped without damaging the cable core. The rubber scraper 504 is biased by 10-15 degrees, so that the scraped rubber particles can be quickly pushed to the outside of the rubber scraper equipment to avoid the situation where the cavity of the rubber scraper head 5 is blocked by the filling rubber particles.

[0020] In this embodiment, efficient glue removal of water-blocking cables is achieved.

[0021] Embodiment 2 This embodiment is an improvement of the previous embodiment. A novel scraper device for water-blocking cables further includes a powder wiping component 3 fixedly installed on the top of the equipment base 1 and on one side of the scraper component 2. The powder wiping component 3 includes two double rings 301. A metal mesh sleeve 302 is arranged between the two double rings 301. The metal mesh sleeve 302 is arranged in a cylindrical shape and is woven by a plurality of metal wires 3021. The weaving density is 35% to 45%. The two ends of the metal wire 3021 are respectively fixedly installed on the two double rings 301. The two double rings 301 each include an inner ring 303 and an outer ring 304. The outer ring 304 is fixedly installed on the top of the equipment base 1 through a support frame 306. The inner ring 303 is rotatably installed inside the outer ring 304. A fastening bolt 305 is passed through and threadedly installed on the outer circumference of the outer ring 304, and one end of the fastening bolt 305 is in contact with the outer circumference of the inner ring 303. The metal wire 3021 includes two metal twisted wires 30211. The surfaces of the outer ring 304 and the inner ring 303 are respectively provided with a plurality of first positioning holes 307 and a second positioning holes 308. The plurality of first positioning holes 307 are distributed in a circular shape, and the plurality of second positioning holes 308 are distributed in a circular shape. In addition, the two ends of one metal twisted wire 30211 in the metal wire 3021 are respectively fixedly installed in the first positioning holes 307 of the two outer rings 304, and the two ends of another metal twisted wire 30211 in the metal wire 3021 are respectively fixedly installed in the second positioning holes 308 of the two inner rings 303.

[0022] As a preferred solution, in order to realize convenient collection of scraped powder, a waste guide bucket 101 is provided through the top of the equipment base 1 and between the two support frames 306, and a waste recovery box 102 used in conjunction with the waste guide bucket 101 is also provided at the bottom of the equipment base 1.

[0023] The advantage of the second embodiment over the first embodiment is that the surface dust of the water-blocking cable can be conveniently wiped off to ensure the surface cleanliness of the water-blocking cable.

[0024] When in use, one end of the water-blocking cable is sequentially passed through the docking ring 502, the hexagonal plug-in tube 501, the stepped sleeve 402, the inner ring 303 of a double ring member 301, the metal mesh sleeve 302 and the inner ring 303 of another double ring member 301, and then one end of the water-blocking cable is horizontally pulled by an external pulling device to move; The servo motor 401 is started, and the servo motor 401 drives the stepped sleeve 402 to rotate through the V-belt transmission member 403, and the stepped sleeve 402 drives the hexagonal plug-in sleeve 501 to rotate the docking ring 502, and the docking ring 502 drives the film mold sleeve 503 to rotate the scraping film 504. At this time, as the water-blocking cable is pulled, the three scraping film 504 are ensured to be aligned with the twisting direction of the water-blocking cable, so that the scraping operation can be realized in the process of the water-blocking cable being pulled and moved; When the water-blocking cable with the glue scraped off passes through the metal mesh sleeve 302 area, the metal mesh sleeve 302 generates friction with the surface of the water-blocking cable to wipe off the dust on the surface of the water-blocking cable, and then the dust falls into the waste recovery box 102 through the waste guide bucket 101.

[0025] It should be noted that when the friction between the metal mesh sleeve 302 and the water-blocking cable needs to be adjusted, the fastening bolts 305 are loosened to rotate the inner ring 303 coaxially relative to the outer ring 304 by a certain angle, and then the friction between the metal mesh sleeve 302 and the water-blocking cable can be fine-tuned.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
