Description

TECHNICAL FIELD

[0002] Wire and cable are wire products used to transmit electric energy, information and realize electromagnetic energy conversion. In a broad sense, wire and cable are also referred to as cable. In a narrow sense, cable refers to insulated cable, which can be defined as one or more insulated cores and their respective possible cladding layers.

[0003] The existing coating device usually melts the plastic raw material first, then coats the molten material on the cable core, and uses a winding device to pull the cable core outwards. In the process of pulling out, a cooling device is used to cool the coating layer to make it quickly set. However, sudden instability of the screw and traction speed or uneven mixing of the material will cause the surface of the insulation layer to appear bulges or unevenness, which may cause the coating layer of the cable to have local uneven thickness. At this time, the technical personnel need to use a knife or a corresponding device to scrape or trim the uneven places. For the recessed part, a plastic strip of the same material and color is used to fill by a hot air plastic welding gun, and then the compaction and compaction are ensured to make the repaired place flat.

[0034] Cutting mechanism 8 is used for annular and longitudinal cutting of defective cable sheath, and the cutting mechanism 8 is arranged at the bottom end of the extrusion rod 14.

[0035] Continuous mechanism 9 can move the cable while cutting annularly, thereby improving efficiency, and the continuous mechanism 9 is arranged inside the bottom end of the extrusion rod 14.

[0036] And retracting mechanism 10 is matched with the extrusion rod 14, so that the cutting knife can be quickly extended and retracted, thereby increasing the accuracy of the cutting position, preventing excessive peeling, improving the efficiency of subsequent complete peeling, and the retracting mechanism 10 is arranged inside the bottom end of the extrusion rod 14.

[0037] The fixed block 5 is annularly and equidistantly provided with a plurality of fixed blocks.

[0038] Specifically, through the arrangement of the cutting mechanism 8, the cable cladding layer can be immediately cut automatically after the cable cladding layer has a problem, so that the efficiency is not reduced by subsequent production and manual cutting and trimming, and the cutting mechanism 8 is arranged on the side away from the cladding part 2 of the cooling part 1, so that the cladding layer after cooling is peeled off, preventing the cladding layer from being peeled off before cooling, so that the plastic adheres to the peeling device and affects the subsequent work.

[0039] Through the movable arrangement of the movable block 91, the movable block 91 can continue to move with the cable during annular cutting, and the movable block 91 can move relative to the cable during transverse cutting, so that annular and transverse cutting can be ensured, and the cable can be cut while moving, thereby improving the overall trimming efficiency.

[0040] Through the arrangement of the retracting mechanism 10, the extrusion frame 99 can make the needle cone 83 and the annular knife 81 extend and retract instantaneously, thereby increasing the accuracy of the cutting position, preventing excessive peeling, reducing the time of subsequent re-cladding, and improving the efficiency of subsequent complete peeling.

[0041] The longer the cable part detected by the detection assembly 4, the more the electric rod 92 moves downward, which makes the cooperation of the triangular block 93 and the sliding plate 94 change the distance of the limiting block 97 moving upward, and then the length of the transverse cutting can be changed, so that the cutting length is prevented from being too long or too short, and the cutting effect is reduced or the speed of subsequent re-coating is increased.

[0042] In still another embodiment of the present application, the continuous mechanism 9 comprises a movable block 91 slidingly arranged at the bottom end of the extension rod 14, the electric rod 92 is fixedly connected to the lower side wall of one end of the extrusion rod 11 close to the extension rod 14, and the bottom end of the electric rod 92 is fixedly connected with a triangular block 93, the sliding plate 94 is slidingly arranged in the extension rod 14 below the lower side of the triangular block 93, the bottom end of the sliding plate 94 is provided with a clamping groove 95, one end of the sliding plate 94 is fixedly connected with a spring 96 between the extension rod 14, the limiting block 97 is movably inserted into the extension rod 14 below the lower side of the sliding plate 94, one end of the limiting block 97 is fixedly connected with a spring 98 between the extension rod 14, the extrusion frame 99 is movably inserted into the extension rod 14 close to one end of the limiting block 97, the trapezoidal block 910 is slidingly connected to the lower end of the extrusion frame 99, the spring 911 is fixedly connected between the extrusion frame 99 away from the limiting block 97 and the movable block 91, and the limiting frame 101 is fixedly connected to the end of the extrusion frame 99 away from the limiting block 97.

[0043] Specifically, through the movable arrangement of the movable block 91, when the ring cutting is performed, the movable block 91 will continue to move with the cable, and when the transverse cutting is performed, the movable block 91 will move relative to the cable, so that the ring cutting and the transverse cutting can be ensured, and the cable can be cut while moving, thereby improving the overall trimming efficiency.

[0044] In still another embodiment of the present application, the retracting mechanism 10 comprises a limiting frame 101, the trapezoidal rod 102 is abutted at the bottom end of the limiting frame 101, and the trapezoidal rod 102 is movably inserted into the bottom end of the movable block 91, the spring 103 is fixedly connected between the upper end of the trapezoidal rod 102 and the movable block 91, the insertion plate 105 is fixedly connected to the extension rod 14 on the side of the limiting block 97 away from the trapezoidal block 910, and the button 104 is arranged on the lower side of the insertion plate 105 in the extension rod 14.

[0045] The electromagnetic block 13 can be started after the detection assembly 4 detects the cable defects, and the magnetic force of the electromagnetic block 13 can be reversed after the button 104 is started.

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

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

[0048] In still another embodiment of the present application, the cutting mechanism 8 comprises a sleeve rod 85 fixed to the bottom end of the trapezoidal rod 102, and a movable rod 84 movably inserted into the sleeve rod 85 at the bottom end, and a needle cone 83 fixed to the bottom end of the movable rod 84, and an arc-shaped slot 89 formed in the upper end of the sleeve rod 85, and a sliding block 88 slidably arranged in the arc-shaped slot 89, and a spring three 810 fixed between one end of the sliding block 88 and the sleeve rod 85, and a connecting rod 82 fixed to the other end of the sliding block 88, and a ring-shaped knife 81 fixed to the bottom end of the connecting rod 82, and a contact block 811 movably inserted into the sliding block 88 away from the spring three 810, and the connecting rod 82 slidably arranged at one end of the contact block 811 in the sliding block 88, and a spring four 812 fixed between the connecting rod 82 and the sliding block 88.

[0049] A plurality of equidistant circular grooves are formed in the upper end of the movable rod 84, and a limiting rod 86 movably inserted into the sleeve rod 85 and the movable rod 84, and a spring two 87 fixed between one end of the limiting rod 86 extending out of the sleeve rod 85 and the sleeve rod 85.

[0050] Specifically, through the arrangement of the cutting mechanism 8, the cable coating layer can be automatically cut immediately after the problem occurs, preventing the subsequent production from being cut and trimmed by manual work to reduce efficiency, and the cutting mechanism 8 is placed on the side of the cooling part 1 away from the coating part 2, so that the coated layer after cooling is peeled off, preventing the coating layer from being peeled off before cooling, so that the plastic adheres to the peeling device, affecting the subsequent work.

[0051] Working principle: when in use, the cable is cooled by water spraying in the cooling part 1 after coming out of the coating part 2, and then is wound up through the connecting block 3 and the detection assembly 4, and the cooperation of the lifting frame 12 and the spring nine 15 can reduce the shaking of the cable. When the coating layer on the outer wall of the cable is uneven, the detection assembly 4 detects that the cable continues to move from the coating part 2 to the connecting block 3, and when the coating layer no longer appears uneven after moving a short distance, the cooling part 1 stops spraying water, and the detection assembly 4 pulls the cable in the opposite direction, and the electromagnetic block 13 is magnetized by the detection assembly 4.

[0052] Because the extrusion rod 11 is magnetic at one end close to the electromagnetic block 13, the electromagnetic block 13 will instantly attract 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 6, and the extension rod 14 pierces downward the lower sleeve rod 85, the movable rod 84 and the needle cone 83, so that the needle cone 83 and the annular knife 81 pierce into the sheath layer, when the cable moves reversely, the movable rod 84 and the needle cone 83 also move with the cable, and the movable block 91 moves towards the limiting block 97, when the extrusion frame 99 is extruded by the limiting 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 two opposite sliding blocks 88 away from each other, and then the sliding blocks 88 drive the connecting rod 82 and the annular knife 81 to move to both sides, thereby being able to cut the sheath layer of the cable of different diameters in a ring shape, and then the contact pressure block 811 is pressed inward by the sleeve rod 85, so that the connecting rod 82 moves upward, thereby making the annular knife 81 move out of the sheath layer, and then the movable block 91 is extruded by the limiting block 97, so that the needle cone 83 can transversely cut the sheath layer;

[0053] When the transverse cutting is completed, the electric rod 92 will press the triangular block 93 downward, so that the clamping groove 95 can move to the position directly above the limiting block 97, thereby making the limiting block 97 move upward, so that the movable block 91 continues to move with the cable, and the annular knife 81 also cuts into the sheath layer again, when the extrusion frame 99 approaches the plugboard 105, the extrusion frame 99 is pressed inward, so that the annular knife 81 cuts again in a ring shape, and the extrusion frame 99 continues to be pressed inward, so that the recess at the lower end of the limiting frame 101 is located directly above the trapezoidal rod 102, the trapezoidal rod 102 moves upward, so that the needle cone 83 and the annular knife 81 move upward and away from the cable, at this time, the button 104 is pressed, so that the electromagnetic block 13 reverses the magnetism through the wire connected thereto, and the electric rod 92 also moves upward again, and then the staff can quickly peel off the cut sheath, and finally the cable after peeling off the sheath is placed into the sheath part 2 again to be sheathed again.

[0054] The longer the cable part detected by the detection assembly 4, the more the electric rod 92 moves downward, which makes the cooperation of the triangular block 93 and the sliding plate 94 change the distance of the upward movement of the limiting block 97, thereby changing the length of the transverse cutting, preventing the cutting length from being too long or too short, and reducing the cutting effect or increasing the speed of subsequent re-sheathing, and through the adjustment of the movable rod 84, different diameters of cables can be adapted.

[0055] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
