Description

Technical fields:

[0001] This utility model relates to the technical field of wire stripping equipment, and specifically to a high-efficiency automatic wire trimming device. Background technology:

[0002] Cable filler rope is an important auxiliary material in cable manufacturing. Its main function is to fill the voids inside the cable, maintaining its roundness and structural stability. In addition, filler rope can improve the tensile and compressive strength of the cable, extending its service life. It also has a flame-retardant effect. Cable filler rope has continuously improved with the development of the cable industry, evolving from initial natural fiber filler materials to synthetic polymer filler ropes, resulting in significantly enhanced performance.

[0003] Many cables have filling cotton ropes. When it is necessary to produce a cable without filling cotton ropes, it is generally necessary to use wire stripping equipment to cut the wire, strip the outer sheath, remove the filling cotton ropes, and retain the core wires for the production of other cables. Currently, there are wire stripping machines on the market that can strip the outer sheath of cables. For example, Chinese utility model patent application CN205509213U discloses a heat stripping machine for anti-scalding wires, which includes: a frame, a lower blade holder, an upper blade holder, a lower cutter, an upper cutter, and a drive mechanism. The lower blade holder is fixed on the frame, and the upper blade holder is movably mounted on the frame and located directly above the lower blade holder. The drive mechanism drives the upper blade holder to move up and down. The top surface of the lower blade holder is covered with a first lower anti-scalding plate, and the front side of the lower cutter is provided with a second lower anti-scalding plate. The bottom surface of the upper blade holder is covered with a first upper anti-scalding plate, and the front side of the upper cutter is provided with a second upper anti-scalding plate. By installing heating elements in both the lower and upper cutter holders to heat the lower and upper cutters, the high temperature during operation allows for rapid and thorough melting and cutting of the nylon outer sheath, effectively improving the efficiency and quality of stripping. Furthermore, the presence of anti-scalding plates effectively prevents the core wire inside the wire from being burned by the cutter holders, thus enhancing operational safety.

[0004] However, this existing heat-stripping machine for anti-scalding threads still has the following shortcomings:

[0005] In this technical solution, multiple anti-scalding plates are set to prevent the high-temperature cutter from burning the wire core during equipment operation, thereby achieving rapid stripping of the cable sheath without damaging the wire core. However, it cannot effectively trim the cable filling cotton rope, so it still needs to be trimmed manually (hot cutting). The manual trimming process of filling cotton rope is prone to exposing the conductor due to excessive trimming force, and may even burn the core wire, causing serious performance risks.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency automatic wire trimming device.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-efficiency automatic wire trimming device, comprising: a workbench, on which slide rails are arranged in a longitudinal direction; a preheating module, which is arranged on the workbench and used to preheat the wire; a cutting module, which is arranged on the workbench and used to trim the cotton rope from the preheated wire; a hot melt suction head module, which is arranged on the workbench and used to remove residual cotton rope from the trimmed wire at high temperature; and multiple sets of wire clamps, which are arranged on the slide rails in a reciprocating manner and used to clamp the wire and move it along the slide rails.

[0009] Furthermore, in the above technical solution, the blower preheating module includes a mounting base plate disposed on the workbench, a first lifting cylinder disposed on the mounting base plate, a lifting blower frame driven by the first lifting cylinder for lifting, and at least one blower head mounted on the lifting blower frame for blower preheating, wherein at least one first mounting arm for mounting the blower head extends from the lifting blower frame.

[0010] Furthermore, in the above technical solution, there are two first mounting arms, and correspondingly, there are two blower heads mounted on the first mounting arms.

[0011] Furthermore, in the above technical solution, the cutting module includes a fixed cutting base disposed on the workbench, a second telescopic cylinder disposed on the fixed cutting base, a high-temperature cutting frame driven by the second telescopic cylinder, and at least one high-temperature cutting blade disposed on the high-temperature cutting frame for trimming wires and cotton ropes.

[0012] Furthermore, in the above technical solution, the number of high-temperature cutting blades is two, and the two high-temperature cutting blades are respectively disposed at both ends of the high-temperature cutting blade holder.

[0013] Furthermore, in the above technical solution, the hot melt suction head module includes a hot melt machine set on the workbench for removing residual cotton rope from the wire at high temperature, a suction head set above the slide rail for picking up the cotton rope, and a connecting pipe communicating with the suction head.

[0014] Furthermore, in the above technical solution, the workbench is also provided with a protective cover to prevent foreign objects from falling, and the protective cover extends above the workbench.

[0015] Furthermore, in the above technical solution, one end of the connecting tube is connected to the suction head, and the other end of the connecting tube is connected to the protective cover, so as to discharge the sucked cotton rope outward.

[0016] Furthermore, in the above technical solution, the number of wire clamps is three, wherein each group includes two wire clamps; the wire clamps are provided with clamping holes for wires to pass through.

[0017] Furthermore, in the above technical solution, the lower end of the workbench is provided with at least four supporting legs; the protective cover is also provided with a first window and a second window.

[0018] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This utility model can automatically trim the filling cotton rope of the cable after the outer sheath has been stripped without damaging the core wire. Specifically, the cable is preheated by a blower preheating module to facilitate subsequent trimming. The cutting module uses the principle that cotton rope is afraid of high temperature to cut off the main filling cotton rope on the cable. Finally, the hot melt suction head module further melts away the remaining small filling cotton rope, and the trimmed filling cotton rope and the gas generated during the hot melt are extracted from the workbench and discharged outwards. The three modules trim the filling cotton rope of the cable in three steps, which can ensure that the filling cotton rope is completely removed without damaging the core wire. In addition, compared with the existing manual trimming, this utility model is a fully automatic trimming, which can greatly improve the trimming efficiency, free up operators, and can be widely applied to various cable stripping and trimming equipment.

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figures 1 to 5As shown, a high-efficiency automatic wire trimming device includes: a workbench 1, on which slide rails 11 distributed along the longitudinal direction are provided; a preheating module 20, which is disposed on the workbench 1 and used to preheat the cable; a cutting module 30, which is disposed on the workbench 1 and used to trim the cotton rope of the preheated cable; a hot melt suction head module 40, which is disposed on the workbench 1 and used to remove residual cotton rope from the trimmed cable at high temperature; and multiple sets of wire clamps 50, which are disposed on the slide rails 11 in a reciprocating manner and used to clamp the cable and move it along the slide rails 11.

[0026] This invention enables automatic trimming of the filler ropes from stripped cables without damaging the core wires. Specifically, a preheating module 20 preheats the cable to facilitate subsequent trimming. A cutting module 30 uses the principle that filler ropes are sensitive to high temperatures to heat-cut the main filler ropes on the cable. Finally, a heat-melting suction head module 40 further melts away any remaining fine filler ropes. The trimmed filler ropes and gases generated during the heat-melting process are then extracted from the workbench 1 and discharged. These three modules work in three steps to trim the filler ropes, ensuring complete removal without damaging the core wires. Furthermore, compared to existing manual trimming, this invention is fully automated, significantly improving trimming efficiency, freeing up operators, and can be widely applied to various cable stripping and trimming equipment.

[0027] The air blowing preheating module 20 includes a mounting base plate 201 disposed on the workbench 1, a first lifting cylinder 202 disposed on the mounting base plate 201, a lifting air blowing frame 203 driven by the first lifting cylinder 202 for lifting and lowering, and at least one air blowing head 204 mounted on the lifting air blowing frame 203 for air blowing preheating, wherein at least one first mounting arm 205 for mounting the air blowing head 204 extends from the lifting air blowing frame 203. Here, the blower head 204 can be raised and lowered along with the lifting blower frame 203. When the cable is held by the cable clamp 50 and moved to the front of the blower preheating module 20, the first lifting cylinder 202 drives the lifting blower frame 203 to move downward, so that the blower head 204 is directly facing the cable held by the cable clamp 50, so as to accurately preheat the cable and initially separate the filling cotton rope. After preheating, the lifting blower frame 203 will lift up with the blower head 204, and the cable clamp 50 will carry the cable to the next module, and so on.

[0028] The wire clamps 50 are arranged in three groups, with each group consisting of two wire clamps 50. Each wire clamp 50 has a clamping hole 501 for the wire to pass through. There are two first mounting arms 205, and correspondingly, two blower heads 204 are mounted on the first mounting arms 205. Here, each group of wire clamps 50 can carry two cables at a time for processing, ensuring efficient trimming.

[0029] The cutting module 30 includes a fixed cutting base 301 disposed on the workbench 1, a second telescopic cylinder 302 disposed on the fixed cutting base 301, a high-temperature cutting frame 303 driven by the second telescopic cylinder 302, and at least one high-temperature cutting blade 304 disposed on the high-temperature cutting frame 303 for trimming cable cotton rope. Here, utilizing the principle that the filling cotton rope is afraid of high temperatures, the high-temperature cutting blade 304 is heated to increase its temperature, thereby cutting the filling cotton rope of the cable. In addition, the high-temperature cutting blade 304 can extend and retract along with the high-temperature cutting blade holder 303. When the cable is held by the wire clamp 50 and moved to the front of the cutting blade module 30, the second telescopic cylinder 302 drives the high-temperature cutting blade holder 303 to extend forward, carrying the high-temperature cutting blade 304 forward. The high-temperature cutting blade 304 cuts the filling cotton rope of the cable. After cutting, the high-temperature cutting blade holder 303 retracts to avoid the high-temperature cutting blade 304 accidentally burning the core wire.

[0030] The number of high-temperature cutting blades 304 is two, and the two high-temperature cutting blades 304 are respectively disposed at both ends of the high-temperature cutting blade holder 303.

[0031] The hot melt suction head module 40 includes a hot melt machine 401 mounted on the workbench 1 for removing residual cotton rope from cables at high temperatures, a suction head 403 mounted above the slide rail 11 for absorbing the cotton rope, and a connecting pipe 404 communicating with the suction head 403. Here, when the cable is clamped by the cable clamp 50 and moved in front of the hot melt machine 401, the hot melt machine 401 emits high temperature at close range to the cable, quickly melting away the small cotton rope remaining after the cable is trimmed. At the same time, the suction head 403 draws the trimmed filling cotton rope and the gas generated during the hot melt process away from the workbench 1 and discharges it outwards.

[0032] The workbench 1 is also provided with a protective cover 101 to prevent foreign objects from falling, and the protective cover 101 extends above the workbench 1.

[0033] One end of the connecting tube 404 is connected to the suction head 403, and the other end of the connecting tube 404 is connected to the protective cover 101 to discharge the sucked cotton rope outward.

[0034] The workbench 1 is provided with at least four supporting feet 102 at its lower end; the protective cover 101 is also provided with a first window 103 and a second window 104. Here, the first window 103 and the second window 104 are provided on the protective cover 101 to facilitate observation of the equipment's operation.

[0035] In summary, this invention can automatically trim the filler ropes of cables after the outer sheath has been stripped without damaging the core wire. Specifically, the cable is preheated by a blower preheating module 20 to facilitate subsequent trimming. The cutting module 30 uses the principle that the filler rope is sensitive to high temperatures to heat-cut the main filler ropes on the cable. Finally, the hot melt suction head module 40 further melts away any remaining small filler ropes, and the trimmed filler ropes and the gas generated during the hot melt process are extracted from the workbench 1 and discharged outwards. The three modules work in three steps to trim the filler ropes of the cable, ensuring that the filler ropes are completely removed without damaging the core wire. In addition, compared with existing manual trimming, this invention is a fully automatic trimming method, which can greatly improve trimming efficiency, free up operators, and can be widely applied to various cable stripping and trimming equipment.
