Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, in particular to a conductor surface pretreatment device for cable manufacturing. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as one or more insulating cores and their respective coatings.

[0003] The existing coating device usually melts the plastic raw material first and then coats the molten material on the cable core, and uses a winding device to pull the cable core outward. During the pulling process, the coating layer is cooled by a cooling device to quickly shape it. However, sudden instability of the screw and pulling speed or uneven mixing of materials will cause bulging or unevenness on the surface of the insulation layer, which may cause the cable coating layer to have uneven thickness locally. At this time, technicians are required to use a knife or corresponding device to scrape the coating layer flat or trim the uneven parts. For the concave parts, plastic strips of the same material and color are used to fill them with a hot air plastic welding gun, and then compacted and pressed to ensure that the repaired part is flat, which is more cumbersome and reduces work efficiency.

[0037] A plurality of fixing blocks 5 are arranged in a ring shape at equal intervals.

[0038] Specifically, by setting the cutting mechanism 8, when there is a problem with the cable coating, it can be automatically cut immediately to prevent the subsequent production from being reduced in efficiency by manual cutting and trimming, and the cutting mechanism 8 is placed on the side of the cooling part 1 away from the coating part 2, so that the coating can be peeled off after cooling, to prevent peeling off before cooling, so that the plastic adheres to the peeling device and affects the subsequent work;

[0039] Through the movable setting of the movable block 91, the movable block 91 can continue to move with the cable during circumferential cutting, and the movable block 91 can move relative to the cable during transverse cutting, thereby ensuring circumferential and transverse cutting, and the cable can be cut while moving, thereby improving the overall trimming efficiency;

[0040] By setting the retracting mechanism 10, the extrusion frame 99 can make the extension and retraction of the needle cone 83 and the annular knife 81 be completed instantly, thereby increasing the accuracy of the cutting position, preventing over-stripping, reducing the time for subsequent re-wrapping, and improving the efficiency of subsequent complete stripping.

[0041] The longer the cable portion detected by the detection component 4, the more the electric rod 92 will move downward, so that the cooperation between the triangular block 93 and the slide plate 94 can change the distance that the limit block 97 moves upward, and then change the length of the lateral cutting, preventing the cutting length from being too much or too little, which will reduce the cutting effect or increase the speed of subsequent re-wrapping.

[0042] In another embodiment provided by the present invention, the continuous mechanism 9 includes a movable block 91 slidably arranged at the bottom end of the extension rod 14, an electric rod 92 is fixedly connected to the lower side wall of the end of the extrusion rod 11 close to the extension rod 14, and a triangular block 93 is fixedly connected to the bottom end of the electric rod 92, a slide plate 94 is slidably arranged on the lower side of the triangular block 93 in the extension rod 14, a slot 95 is provided at the bottom end of the slide plate 94, a spring five 96 is fixedly connected between one end of the slide plate 94 and the extension rod 14, a limit block 97 is movably inserted in the extension rod 14 at the lower side of the slide plate 94, a spring six 98 is fixedly connected between the upper side of one end of the limit block 97 and the extension rod 14, an extrusion frame 99 is movably inserted at one end of the movable block 91 close to the limit block 97, a trapezoidal block 910 is slidably connected to the lower end of the extrusion frame 99, a spring seven 911 is fixedly connected between the end of the extrusion frame 99 away from the limit block 97 and the movable block 91, and the end of the extrusion frame 99 away from the limit block 97 is fixedly connected to the limit frame 101.

[0043] Specifically, through the movable setting of the movable block 91, the movable block 91 will continue to move with the cable during circumferential cutting, and the movable block 91 will move relative to the cable during transverse cutting, thereby ensuring circumferential and transverse cutting, and the cable can be cut while moving, thereby improving the overall trimming efficiency.

[0044] In another embodiment provided by the present invention, the retracting mechanism 10 includes a limit frame 101, the bottom end of the limit frame 101 abuts against a trapezoidal rod 102, and the trapezoidal rod 102 is movably inserted into the bottom end of the movable block 91, a spring 8 103 is fixedly connected between the upper end of the trapezoidal rod 102 and the movable block 91, and a plug plate 105 is fixedly connected to the extending rod 14 on the side of the limit block 97 away from the trapezoidal block 910, and a button 104 is provided on the lower side of the plug plate 105 on the extending rod 14.

[0045] After the detection component 4 detects a cable defect, the electromagnetic block 13 can be activated, and after the button 104 is activated, the magnetic force of the electromagnetic block 13 can be reversed.

[0046] The limiting frame 101 is an inverted U-shaped structure.

[0047] Specifically, through the setting of the retraction mechanism 10, the extrusion frame 99 can make the extension and retraction of the needle cone 83 and the annular knife 81 be completed instantly, thereby increasing the accuracy of the cutting position, preventing excessive peeling, reducing the time for subsequent re-wrapping, and improving the efficiency of subsequent complete peeling.

[0048] In another embodiment provided by the present invention, the cutting mechanism 8 includes a sleeve rod 85 fixedly connected to the bottom end of the trapezoidal rod 102, and a movable rod 84 is movably inserted into the bottom end of the sleeve rod 85, a needle cone 83 is fixedly connected to the bottom end of the movable rod 84, arc grooves 89 are provided on two opposite sides of the upper end of the sleeve rod 85, and a slider 88 is slidably arranged in the arc groove 89, a spring three 810 is fixedly connected between one end of the slider 88 and the sleeve rod 85, and a connecting rod 82 is fixedly connected to the other end of the slider 88, an annular knife 81 is fixedly connected to the bottom end of the connecting rod 82, a touch block 811 is movably inserted into the end of the slider 88 away from the spring three 810, a connecting rod 82 is slidably arranged at the end of the touch block 811 located in the slider 88, and a spring four 812 is fixedly connected between the upper end of the connecting rod 82 and the slider 88.

[0049] The upper end of the movable rod 84 is provided with a plurality of circular grooves with equal spacing. A limiting rod 86 is movably inserted on the sleeve rod 85 and the movable rod 84 , and a spring 87 is fixedly connected between one end of the limiting rod 86 extending outside the sleeve rod 85 and the sleeve rod 85 .

[0050] Specifically, by setting up the cutting mechanism 8, when a problem occurs in the cable coating, it can be automatically cut immediately to prevent the efficiency from being reduced by manual cutting and trimming after subsequent production. The cutting mechanism 8 is placed on the side of the cooling part 1 away from the coating part 2, so that the coating can be peeled off after cooling, to prevent peeling off before cooling, so that the plastic adheres to the peeling device and affects the subsequent work.

[0051] Working principle: When in use, after the cable comes out of the covering part 2, it will be sprayed with water in the cooling part 1 to cool it down, and then it will be wound up through the connecting block 3 and the detection component 4. The cooperation of the lifting frame 12 and the spring nine 15 can reduce the shaking of the cable. When the covering layer on the outer wall of the cable appears uneven, the detection component 4 will find it after detection. At this time, the cable continues to move from the covering part 2 to the connecting block 3. When the covering layer no longer appears uneven after a short distance, the cooling part 1 will stop spraying water, and the detection component 4 will cause the cable to be pulled in the opposite direction, and the detection component 4 will magnetize the electromagnetic block 13;

[0052] Since the end of the extrusion rod 11 close to the electromagnetic block 13 is magnetic, the electromagnetic block 13 instantly attracts the extrusion rod 11, so that the extrusion rod 11 is away from the extension rod 14, so that the extension rod 14 is quickly pressed downward by the spring 16, and the extension rod 14 pierces the lower sleeve rod 85, the movable rod 84 and the needle cone 83 downward, so that the needle cone 83 and the annular knife 81 pierce into the sheath. When the cable moves in the reverse direction, the movable rod 84 and the needle cone 83 will also move with the cable, and the movable block 91 will move toward the limit block 97. When the extrusion frame 99 is squeezed by the limit block 97, , the extrusion frame 99 will press the trapezoidal block 910 downward, so that the bottom end of the trapezoidal block 910 presses the sliders 88 on the two opposite sides toward the side away from each other, and then the slider 88 drives the connecting rod 82 and the annular knife 81 to move to both sides, so as to be able to circumferentially cut the cable sheaths of different diameters, and then the contact block 811 will be pressed inward by the sleeve rod 85, so that the connecting rod 82 moves upward, so that the annular knife 81 moves out of the sheath, and then the movable block 91 is squeezed by the limit block 97, so that the needle cone 83 can cut the sheath horizontally;

[0053] When the horizontal cutting is completed, the electric rod 92 will press the triangular block 93 downward, so that the card slot 95 can move to the top of the limit block 97, so that the limit block 97 moves upward, so that the movable block 91 will continue to move with the cable, and the annular knife 81 will also cut downward into the coating layer again. When the extrusion frame 99 approaches the plug board 105, the extrusion frame 99 will be pressed inward, so that the annular knife 81 will perform annular cutting again. The extrusion frame 99 continues to press inward, so that the groove at the lower end of the limit frame 101 can be located above the trapezoidal rod 102, and the trapezoidal rod 102 will move upward, so that the needle cone 83 and the annular knife 81 both move upward and leave the cable. At this time, the button 104 will be pressed, so that the electromagnetic block 13 reverses the magnetism of the electromagnetic block 13 through the wire connected to it, and the electric rod 92 also moves upward again. After that, the staff can quickly peel off a section of the outer skin after cutting, and finally put the end of the cable after the outer skin is peeled back into the coating part 2 for coating again;

[0054] The longer the cable portion detected by the detection component 4, the more the electric rod 92 will move downward. This allows the cooperation of the triangular block 93 and the slide plate 94 to change the distance that the limit block 97 moves upward, thereby changing the length of the lateral cutting, preventing the cutting length from being too long or too short, which would reduce the cutting effect or increase the subsequent re-wrapping speed. By adjusting the movable rod 84, it can adapt to cables of different diameters.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and the description in the specification are only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
