Description

Technical Field

[0001] The present invention relates to the technical field of cable recycling and treatment, and particularly to an insulating skin treatment device for cable recycling. Background Art

[0002] A cable is an electrical product used to transmit electricity, signals, or achieve electromagnetic energy conversion. It mainly consists of a wire core, an insulating skin, and a protective sleeve, and there are many types and specifications. In terms of power transmission, conventional power cables are generally selected. If it is used to transmit signal information, television cables, fiber optic cables, or local telephone cables need to be selected. Different types of cables are widely used in daily life, construction projects, industrial production, etc., and have extremely high usage value. With the continuous development of science and technology and industrial productivity, the electricity demand in various fields in China is particularly large. Most of the machinery and equipment require continuous power transmission to maintain operation. However, cables have a certain service life. After aging occurs, a large number of them need to be scrapped and replaced to ensure the stable supply of subsequent electricity. Since the wire core of the cable is made of metal and the external insulating skin is made of rubber, both materials have the value of recycling.

[0003] When recycling and treating waste cables, it is necessary to separate the wire core inside the cable from the external insulating skin. The general methods for treating cables include manual peeling, incineration, mechanical peeling, chemical method, and freezing method. The incineration method used in the early cable recycling and treatment has been prohibited because of its great impact on the environment. The waste liquid generated by the chemical treatment method cannot be effectively treated. The freezing method has good treatment effect but the cost is extremely high. The manual peeling method has low treatment efficiency and high labor cost. Therefore, at present, the mechanical peeling method is mainly used to treat cables. The mechanical peeling method mainly uses a cable peeling machine to separate and treat cables. However, manual assistance is still required during the operation process, which belongs to a semi-automatic operation method, and there are problems of high manual labor intensity and low cable treatment efficiency.

[0017] Working principle: Before using this equipment, it is necessary to pre-set an external winding machine at the left and right ends of the equipment, one for winding up the recycled cables, and the other for winding up the inner core of the stripped cables. In actual use, firstly perform a preliminary stripping on one end of the recycled cable wound on one of the winding machines. In this step, a portable cable stripping knife can be used to process it. After exposing a section of the inner core of the cable, the inner core is passed through the two soft rubber clamping wheels set on the right side of the equipment, the middle of the insulation skin circumcision mechanism on the right side, between the two skin cutting knives, the middle of the insulation skin circumcision mechanism on the left side, and between the two soft rubber clamping wheels set on the left side. Then, the inner core of the cable is wound on another winding machine to complete the entire equipment. The cable preprocessing step is then performed, and then the two linear moving modules inside the operating frame are first started to operate, so that the moving blocks on the linear moving modules drive the insulation skin cutting mechanism to move linearly left and right. When the two insulation skin cutting mechanisms move to appropriate positions, the fourth electric telescopic rod is started to operate, so that its rod body pushes the cutting blade to move toward the cable direction and cuts into the insulation skin of the cable in a vertical direction. When the blade contacts the inner core of the cable, the rod body of the fourth electric telescopic rod stops operating, and the second motor is started to operate at this time, so that the output end of the second motor drives the second gear to rotate. Since one side of the second gear is meshed and connected with multiple grooves on the outer wall of the gear ring, when the second gear rotates, it will synchronously drive the gear ring to rotate, and the gear ring then drives the fourth electric telescopic rod and the cutting blade The cutting blade rotates in a circle, and the cutting blades on both sides perform circumferential cutting and separation on the two ends of the cable insulation skin, and then the position of the insulation skin circumcision mechanism is adjusted to be separated from the circumcision section, and then the first motor fixedly connected to the lower part of the mobile connecting block is started to operate, so that its output end drives the first gear to rotate. Since the top end of the first gear is meshed with the bottom end of the rack, when the first gear rotates, it will cooperate with the limiting relationship between the slider and the slide groove to drive the mobile connecting block to move linearly back and forth, thereby synchronously driving the connecting plate to move, adjusting the position of the U-shaped frame, and then synchronously adjusting the positions of the two skin cutting knives. When the positions of the two skin cutting knives are adjusted to the center position of the cable, the first electric telescopic rod and the third electric telescopic rod are synchronously started to operate, so that the skin cutting knife at the bottom of the square block The bottom end of the second fixed plate and the skin cutting knife at the top of the second fixed plate contact the upper and lower outer skins of the cable, and pierce the outer skin of the cable under the bidirectional pressure of the first electric telescopic rod and the third electric telescopic rod. When the skin cutting knife initially cuts the cable insulation skin for a short distance, the second electric telescopic rod is started to operate, so that the second electric telescopic rod drives the first fixed plate and the blade to move downward, and the two separation blade heads connected by rotation at the bottom of the blade body will be inserted into the cable from the gap cut by the upper skin cutting knife. After contacting the inner core of the cable, the two separation blade heads will separate under the action of pressure and the smooth surface set at the bottom of the separation blade heads, and expand in both directions to stretch the inner core of the cable from the outer insulation skin, and then start the third motor to operate, and the output end of the third motor will drive the threaded rod to rotate.Due to the threaded connection between the threaded holes provided at the lower part of the moving frame and the threaded rod, when the threaded rod rotates, it will drive the moving frame to perform linear movement along the direction of the side groove. When the moving frame moves, it will synchronously drive the insulating skin cutting and peeling mechanism to move. The two skin cutting knives provided on the insulating skin cutting and peeling mechanism cut the insulating skin of the cable from the upper and lower sides, divide the insulating skin of the cable into two halves, and the two separating knife heads perform external peeling treatment on the insulating skin attached to the inner core of the cable. The stripped inner core of the cable is wound on the external winding machine equipment, and the peeled insulating skin will directly fall from the through groove to the upper part of the conveyor belt, and then be conveyed to the receiving box fixedly connected to the right end of the bottom plate, completing the peeling and recycling process of the cable insulating skin. After that, repeating the above steps can perform automatic peeling and recycling operations on a single recycled cable, realizing the classified recycling of the inner core and the external insulating skin of the cable. The automation degree of the entire equipment is high and the recycling efficiency is good.

[0018] (III) Advantageous Effects

[0019] The present invention provides an insulating skin treatment device for cable recycling. It has the following advantageous effects:

[0020] 1. In the present invention, the two ends of the cable are respectively wound on the external winding machine, and then by starting the operation of the two linear movement modules inside the operation frame, the moving blocks on the linear movement modules drive the insulating skin circumcision mechanism to perform left and right linear movement. When the two insulating skin circumcision mechanisms move to the appropriate positions, by starting the operation of the fourth electric telescopic rod, the cutting blade is pushed towards the cable direction and cuts into the insulating skin of the cable in the vertical direction. After the blade touches the inner core of the cable, the second motor is started to operate, so that the output end of the second motor drives the second gear to rotate. The second gear drives the toothed ring to rotate, and the toothed ring drives the fourth electric telescopic rod and the cutting blade to perform circular rotation, realizing the circumferential cutting and separation of the two ends of the insulating skin of the cable by the cutting blades on both sides, and realizing the automatic circumferential cutting and segmentation of the insulating skin on the outer wall of the cable, which is convenient for subsequent cutting and peeling treatment of the cable insulating skin.

[0021] 2. The present invention starts the operation of the first motor fixedly connected to the lower part of the mobile connecting block, so that its output end drives the first gear to rotate. When the first gear rotates, it will cooperate with the limiting relationship between the slider and the slide groove to drive the mobile connecting block to move linearly back and forth, thereby synchronously driving the connecting plate to move, adjusting the position of the U-shaped frame, and then synchronously adjusting the positions of the two skin cutting knives. When the positions of the two skin cutting knives are adjusted to the center position of the cable, the first electric telescopic rod and the third electric telescopic rod are synchronously started to operate, so that the bottom end of the skin cutting knife at the bottom of the square block and the skin cutting knife at the top of the second fixed plate contact the upper and lower outer skins of the cable, and pierce the outer skin of the cable under the bidirectional pressure of the first electric telescopic rod and the third electric telescopic rod. Through the linear movement of the mobile frame, the outer skin of the cable is cut in two directions from the upper and lower sides, so that the insulating skin wrapped around the inner core is separated.

[0022] 3. The present invention takes into account the situation that the insulation skin cut by the two skin cutting knives may still be attached to the inner core of the cable. When the skin cutting knife initially cuts the insulation skin of the cable for a short distance, the second electric telescopic rod is started to operate, so that the second electric telescopic rod drives the first fixed plate and the blade to move downward, and the two separation blade heads rotatably connected at the bottom of the blade will be inserted into the cable from the gap cut by the upper skin cutting knife. After contacting the inner core of the cable, the two separation blade heads will separate under the action of pressure and the smooth surface set at the bottom of the separation blade heads, and expand in both directions to spread the inner core of the cable from the outer insulation skin, and then move to the left side. Driven by the moving frame, the two insulation cutting knives arranged on the insulation stripping mechanism first cut the insulation of the cable from the upper and lower sides, dividing the insulation of the cable into two halves, and then the two separation knife heads peel off the insulation attached to the inner core of the cable by external force, and the stripped cable inner core is wound on an external winding machine device. The stripped insulation will fall directly from the through groove to the upper part of the conveyor belt, and then be conveyed to the material receiving box fixedly connected at the right end of the bottom plate, completing the stripping and recycling process of the cable insulation. The whole process has good stripping effect and fast speed, realizing automated insulation stripping operation. BRIEF DESCRIPTION OF THE DRAWINGS
