A cable recycling stripping assembly

Abstract

This utility model relates to the field of cable recycling technology, specifically to a cable recycling stripping assembly. It includes a base plate, on which a vertical plate is fixedly mounted vertically. Two cutting components are symmetrically arranged on one side of the vertical plate. Each cutting component includes a rotating shaft rotatably mounted on the vertical plate, with a square rod coaxially fixed to the other end of the shaft. A first semi-guide wheel and an annular blade are coaxially slidably mounted on the square rod. In this utility model, when the top rod is rotated to move away from the turntable, a spring pushes a nut away from the turntable. The nut, through a sliding rod, drives the second semi-guide wheel to move backward synchronously until the end of the square rod is completely disengaged from the square groove of the second semi-guide wheel. At this point, the gap between the square rod and the second semi-guide wheel is greater than the thickness of the annular blade, allowing the old blade to be easily removed from the square rod. A new annular blade is then installed, ensuring the cutting edge remains sharp and effectively avoiding the problem of decreased cable stripping efficiency due to blade dulling.

Description

Technical Field

[0001] This utility model relates to the field of cable recycling technology, and more specifically, to a cable recycling stripping assembly. Background Technology

[0002] Cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. Power companies often need to replace many cables after a period of use. However, the replaced cables cannot be reused and can only be used as waste. Since cables consist of two layers, namely the inner core and the outer plastic sheath, it is necessary to separate the inner core and the plastic sheath of the cable in order to better realize the recycling of cables.

[0003] The utility model with authorization announcement number CN221806340U provides a cable stripping device for cable production. Through a set drive mechanism, the cable is placed between a first drive wheel and a first driven wheel. A first motor drives the first drive wheel to rotate, automatically driving the cable to move. Through the set stripping mechanism, the cable enters between a second drive wheel and a second driven wheel. A second motor drives the second drive wheel to rotate, and a cutting blade strips the cable.

[0004] However, the aforementioned patent has obvious shortcomings: First, its cutting blade is fixedly installed on the first drive wheel and the first driven wheel. When the cutting blade becomes dull due to long-term use and needs to be replaced, the first drive wheel and the first driven wheel must be replaced as a whole, which increases maintenance costs and resource consumption. Second, the drive wheel and the driven wheel lack effective support at the end away from the drive mechanism (i.e., the motor side), forming a cantilever structure. This design is prone to a decrease in wheel and axle stability after long-term operation, which in turn affects the accuracy of cable conveying and stripping, and ultimately reduces stripping quality and recycling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a cable recycling and stripping assembly to solve the problems mentioned in the background section.

[0006] When the cutting blade becomes dull due to long-term use and needs to be replaced, the first drive wheel and the first driven wheel need to be replaced as a whole, which increases maintenance costs and resource consumption.

[0007] To address the above problems, the present invention aims to provide a cable recycling and stripping assembly, comprising a base plate, on which a vertical plate is fixedly mounted on the upper sidewall. Two cutting assemblies are symmetrically arranged on one side of the vertical plate. Each cutting assembly includes a rotating shaft rotatably mounted on the vertical plate, and a square rod coaxially fixedly connected to the other end of the rotating shaft. A first semi-guide wheel and an annular blade are coaxially slidably mounted on the square rod. A second semi-guide wheel is provided on the side of the square rod away from the rotating shaft. A corresponding square groove is formed on the side of the second semi-guide wheel facing the square rod. A pressing mechanism is provided on the side of the second semi-guide wheel away from the square rod. The pressing mechanism is used to press the second semi-guide wheel toward the rotating shaft, so that the first semi-guide wheel is tightly attached to the rotating shaft, and at the same time, the end of the square rod is inserted into the square groove, so that the first semi-guide wheel, the annular blade, and the second semi-guide wheel are tightly combined to form a cutting guide wheel.

[0008] As a further improvement to this technical solution, the clamping mechanism includes a turntable, on which a collar is coaxially rotatable, and the collar is fixedly mounted on the upright plate by two connecting brackets.

[0009] As a further improvement to this technical solution, two sliding rods are centrally and symmetrically fixedly connected to the side of the second semi-guide wheel away from the square rod, and the other end of the sliding rod slides through the turntable and is threaded with a nut.

[0010] As a further improvement to this technical solution, a spring that is slidably sleeved on the slide rod is provided between the nut and the turntable, and the spring pushes the nut away from the turntable.

[0011] As a further improvement to this technical solution, a push rod is coaxially threaded onto the turntable, and one end of the push rod contacts the side of the second semi-guide wheel away from the square rod.

[0012] As a further improvement to this technical solution, a circular channel is formed between the two cutting guide wheels, the inner diameter of which is adapted to the outer diameter of the cable, and the outer circumference of the annular blade extends into the interior of the circular channel.

[0013] As a further improvement to this technical solution, a servo motor is fixedly installed on the side of the base plate away from the rotating shaft, and the output shaft of the servo motor is coaxially and fixedly connected to one of the rotating shafts through a coupling.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. When the cable recycling stripping assembly is rotated to move away from the turntable, the spring pushes the nut away from the turntable. The nut drives the second semi-guide wheel to move backward synchronously through the slide rod until the end of the square rod is completely disengaged from the square groove of the second semi-guide wheel. At this time, the gap formed between the square rod and the second semi-guide wheel is greater than the thickness of the annular blade. The old blade can be easily removed from the square rod, and a new annular blade is then installed to ensure that the cutting edge remains sharp and effectively avoid the problem of reduced cable stripping efficiency due to blade dulling.

[0016] 2. In this cable recycling stripping assembly, when the servo motor drives the rotating shaft to rotate, the rotating shaft drives the entire cutting guide wheel to rotate synchronously through the square rod. At the same time, the second half-guide wheel drives the turntable to rotate together through two slide rods. The rigid support structure composed of the collar and connecting frame provides reliable rotation guidance and radial support for the turntable during this process, enhancing the rotational stability of the cutting guide wheel at the end away from the rotating shaft, thereby improving the cutting accuracy and processing quality of the annular blade on the cable sheath.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0029] Please see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a cable recycling and stripping assembly, including a base plate 1. A vertical plate 2 is fixedly installed on the upper side wall of the base plate 1. Two cutting assemblies are symmetrically arranged on one side of the vertical plate 2. Each cutting assembly includes a rotating shaft 3 rotatably mounted on the vertical plate 2. A square rod 31 is coaxially fixedly connected to the other end of the rotating shaft 3. A first semi-guide wheel 4 and an annular blade 5 are coaxially slidably sleeved on the square rod 31. A second semi-guide wheel 6 is arranged on the side of the square rod 31 away from the rotating shaft 3. (Refer to...) Figure 4 The second semi-guide wheel 6 has a corresponding square groove 61 on the side facing the square rod 31, and a pressing mechanism 7 is provided on the side of the second semi-guide wheel 6 away from the square rod 31. The pressing mechanism 7 is used to press the second semi-guide wheel 6 toward the rotating shaft 3. This pressing action achieves three key functions: first, it makes the first semi-guide wheel 4 fit tightly against the rotating shaft 3; second, it makes the end of the square rod 31 inserted into the square groove 61 of the second semi-guide wheel 6; finally, it makes the first semi-guide wheel 4, the annular blade 5 and the second semi-guide wheel 6 fit tightly together to form a stable cutting guide wheel.

[0030] A circular channel is formed between the two cutting guide wheels. The inner diameter of the circular channel is adapted to the outer diameter of the cable. The outer circumference of the annular blade 5 extends into the interior of the circular channel. The cutting edge thickness of the annular blade 5 inside the channel is about 0.9 times the thickness of the cable sheath. This specific dimension ensures that the annular blade 5 can effectively cut through the cable sheath while minimizing damage to the internal wire core. A servo motor 8 is fixedly installed on the side of the base plate 1 away from the rotating shaft 3. Its output shaft is coaxially fixedly connected to one of the rotating shafts 3 through a coupling.

[0031] In addition, two auxiliary guide wheels are rotatably connected to the upright plate 2, forming another circular channel between the two auxiliary guide wheels. The axes of the two circular channels are strictly collinear, forming a straight cable transport path. A drive motor is fixedly installed on the upright plate 2, which drives one of the auxiliary guide wheels to rotate. During operation, the operator passes the cable through the two collinear circular channels in sequence. The cable maintains close contact with both the cutting guide wheel and the auxiliary guide wheel. The constraint of the channel keeps the cable straight during transport. At this time, the cutting edges of the two annular blades 5 have precisely cut into the cable sheath.

[0032] After the servo motor 8 and the drive motor start synchronously, the servo motor 8 drives the rotating shaft 3 and the square rod 31 connected to it to rotate, which in turn drives the corresponding cutting guide wheel to rotate as a whole. The drive motor drives one of the auxiliary guide wheels to rotate. The rotating cutting guide wheel and the auxiliary guide wheel pull the cable together through the friction between them and the cable surface, so that the cable moves stably. The moving cable then drives another cutting guide wheel and another auxiliary guide wheel to rotate passively through the friction, thereby realizing the continuous conveying of the cable. During this conveying process, the two annular blades 5 that cut into the cable sheath work together to cut the cable sheath at the same time, and efficiently perform the cable stripping operation.

[0033] The structure of the clamping mechanism 7 is described in detail below, with reference to... Figure 3 The clamping mechanism 7 includes a turntable 71, on which a collar 72 is coaxially rotatably mounted. The collar 72 is fixedly mounted on the upright plate 2 by two connecting brackets 721. Two sliding rods 73 are centrally and symmetrically fixedly connected to the side of the second semi-guide wheel 6 away from the square rod 31. The other end of the sliding rod 73 slides through the turntable 71 and is threadedly connected to a nut 74. A spring 75 is slidably sleeved on the sliding rod 73 between the nut 74 and the turntable 71. The spring 75 pushes the nut 74 away from the turntable 71. A push rod 76 is coaxially threadedly connected to the turntable 71. One end of the push rod 76 contacts the side of the second semi-guide wheel 6 away from the square rod 31, and the other end of the push rod 76 is coaxially fixedly connected to a bolt head.

[0034] During operation, the operator uses a tool to rotate the push rod 76. Utilizing the threaded engagement between the push rod 76 and the turntable 71, the rotational action drives the push rod 76 to move along its own axis. When the push rod 76 is screwed closer to the rotating shaft 3, it pushes the second semi-guide wheel 6 to move synchronously along the axis of the slide rod 73. During this process, the second semi-guide wheel 6 drives the nut 74 to move closer to the turntable 71 through the slide rod 73, causing the spring 75 to be compressed and contracted. The push rod 76 is continuously screwed in until the first semi-guide wheel 4, the annular blade 5, and the second semi-guide wheel 6 reach a tight fit. At this point, the rotation is stopped. The push rod 76 maintains a stable position under the self-locking action of the thread, ensuring a stable combination of the cutting guide wheels.

[0035] When the servo motor 8 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the entire cutting guide wheel (first semi-guide wheel 4, annular blade 5, and second semi-guide wheel 6) to rotate synchronously through the square rod 31. The second semi-guide wheel 6 drives the turntable 71 to rotate together through the two slide rods 73. At this time, the support structure formed by the collar 72 and the connecting frame 721 plays the role of rotation guidance and support for the turntable 71, thereby enhancing the rotational stability of the cutting guide wheel on the side away from the rotating shaft 3 and improving the cutting accuracy and quality of the annular blade 5 on the cable sheath.

[0036] When the annular blade 5 becomes dull due to prolonged use and needs to be replaced, refer to... Figure 5The operation procedure is as follows: The operator rotates the top rod 76 in the opposite direction, moving it away from the turntable 71. After the top rod 76 retracts, the compressed spring 75 is released, and its rebound force pushes the nut 74 away from the turntable 71. The nut 74 drives the second semi-guide wheel 6 to move synchronously through the slide rod 73 until the end of the square rod 31 is completely removed from the square groove 61 of the second semi-guide wheel 6, and a gap greater than the thickness of the annular blade 5 is formed between the square rod 31 and the second semi-guide wheel 6. Then the operator can remove the old annular blade 5 from the square rod 31. When replacing it, the new annular blade 5 is slidably fitted onto the square rod 31. Finally, the top rod 76 is rotated again to re-tighten and form a stable cutting guide wheel unit to complete the replacement.
