Description

Technical Field

[0001] This utility model relates to the technical field of cable recycling and processing equipment, and in particular to a cable stripping device. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, and power transmission lines for internal power supply in industrial and mining enterprises. When recycling cables, it is necessary to clean and strip them. Stripping allows the outer plastic and the internal copper wires to be recycled.

[0003] Existing wire stripping equipment requires the cable sheath to be crushed in a crushing device after being stripped during use, but current stripping equipment does not have a crushing function and is not convenient for separating the cable sheath from the armor metal sheet.

[0004] To address this issue, a wire stripping device is proposed, which has the advantages of easily breaking the wire sheath and separating the armor layer metal sheets, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wire stripping device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire stripping device, comprising a housing, a stripping chamber formed in the upper part of the inner side of the housing, and a crushing chamber formed in the lower part of the inner side of the housing. A lower cutting wheel is installed inside the stripping chamber, and an upper cutting wheel is arranged above the lower cutting wheel. A mounting base is rotatably mounted on the periphery of the upper cutting wheel, and a lifting sleeve is arranged above the mounting base. A support is welded to the top surface of the housing, and a threaded rod is threadedly installed on the surface of the support. The bottom of the threaded rod is connected to a shaft. The base is connected to the top of the lifting sleeve. A constant force spring is installed between the lifting sleeve and the mounting base. An arc-shaped guide shell is connected between the stripping chamber and the crushing chamber. An observation port is opened in the middle of the outer surface of the arc-shaped guide shell, and a material drop port is opened at the upper end of the inner side of the arc-shaped guide shell. A first motor is fixed on the side wall of the machine housing, and a transmission belt that is wound and connected to the lower cutter wheel is provided at the output end of the first motor. A second motor is fixedly installed inside the machine housing, and a crushing cutter disc that extends to the crushing chamber is fixed at the output end of the second motor.

[0007] As a further description of the above technical solution: both the upper and lower cutter wheels have annular grooves on their surfaces, and the cross-section of the annular grooves is an arc-shaped structure. An annular cutter is provided in the middle of the annular grooves, and a set of arc protrusions are respectively arranged around the left and right sides inside the annular grooves, and the two arc protrusions are symmetrically arranged about the annular cutter.

[0008] As a further description of the above technical solution: the left side wall of the housing has a feeding inlet through the stripping cavity, and the top surface of the housing has a clearance opening through the stripping cavity, the size of which matches the size of the lifting sleeve.

[0009] As a further description of the above technical solution: the cross-section of the arc-shaped material guide shell is U-shaped, and two baffles are symmetrically welded to the lower inner side of the arc-shaped material guide shell corresponding to the observation port, and a gap is reserved between the two baffles on the inner side of the arc-shaped material guide shell.

[0010] As a further description of the above technical solution: a guide hopper is welded to the bottom of the casing, and the guide hopper is connected to the crushing chamber of the casing.

[0011] As a further description of the above technical solution: a plurality of arc blades are arranged around the crushing disc, and a mounting hole is provided at the center of the crushing disc.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, an arc-shaped guide shell connects the stripping chamber and the crushing chamber of the casing. A discharge port is opened on the upper inner side of the arc-shaped guide shell, and an observation port is opened in the middle of the outer surface of the arc-shaped guide shell. As the annular cutters of the lower and upper cutter wheels strip the cable sheath, the cable sheath extends along the arc surface of the inner side of the arc-shaped guide shell into the crushing chamber for crushing under the transmission action of the lower and upper cutter wheels. During this process, the metal sheet of the inner armor layer of the cable disperses and is discharged from the discharge port under the action of gravity. The observation port facilitates the auxiliary guidance of the cable sheath, so that the cable sheath can accurately enter the crushing chamber and pull the cable guide wire to the outside of the observation port. With this structure, the cable stripping is satisfied while the outer sheath is easily crushed and the cable guide wire and the metal sheet of the armor layer are separated.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a wire stripping device according to an embodiment of the present invention includes a housing 1. A stripping chamber 2 is formed in the upper part of the inner side of the housing 1, and a crushing chamber 3 is formed in the lower part of the inner side of the housing 1. A lower-level cutter wheel 5 is installed inside the stripping chamber 2, and an upper-level cutter wheel 6 is arranged above the lower-level cutter wheel 5. A mounting base 10 is rotatably mounted around the upper-level cutter wheel 6, and a lifting sleeve 9 is arranged above the mounting base 10. A support 7 is welded to the top surface of the housing 1, and a threaded rod 8 is threaded onto the surface of the support 7. The bottom of the threaded rod 8 is connected to the top of the lifting sleeve 9 through a shaft seat. A constant force spring 11 is installed between the lifting sleeve 9 and the mounting base 10. An arc-shaped guide shell 14 connects the stripping chamber 2 and the crushing chamber 3, and an observation port 22 is formed in the middle of the outer surface of the arc-shaped guide shell 14. An opening is formed at the upper end of the inner side of the arc-shaped guide shell 14. The device has a material discharge port 15. A first motor 4 is fixed to the side wall of the housing 1, and the output end of the first motor 4 is provided with a transmission belt 13 that is wound and connected to the lower cutter wheel 5. A second motor 16 is fixedly installed inside the housing 1, and the output end of the second motor 16 is fixed with a crushing disc 17 extending to the crushing chamber 3. The first motor 4 and the second motor 16 are controlled by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Since this device is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail. The lower cutter wheel 5 at the front end of the device is connected to the transmission belt 13 of the first motor 4. The other lower cutter wheels 5 can be driven by a drive motor, chain and sprocket (not shown in the figure).

[0023] In one embodiment, both the upper cutter wheel 6 and the lower cutter wheel 5 have annular grooves 19 on their surfaces, and the cross-section of the annular grooves 19 is an arc-shaped structure. An annular cutter 20 is provided in the middle of the annular grooves 19. A set of arc-shaped protrusions 21 are respectively arranged around the left and right sides inside the annular grooves 19, and the two arc-shaped protrusions 21 are symmetrically arranged about the annular cutter 20. With this structure, the arc-shaped protrusions 21 are used for the transmission of wires and cables, and the annular cutter 20 is used for cutting wires and cables. The arc-shaped structure of the annular grooves 19 fits the outline of the wires and cables.

[0024] In one embodiment, the left side wall of the housing 1 has a feeding inlet 12 that passes through the stripping cavity 2, and the top surface of the housing 1 has a clearance opening that passes through the stripping cavity 2. The size of the clearance opening of the housing 1 matches the size of the lifting sleeve 9. This structure facilitates the feeding of wires and cables, and guides and clears the lifting sleeve 9 through the clearance opening.

[0025] In one embodiment, the cross-section of the arc-shaped guide shell 14 is U-shaped, and two baffles are symmetrically welded to the lower inner side of the arc-shaped guide shell 14 corresponding to the observation port 22. A gap is reserved between the two baffles on the inner side of the arc-shaped guide shell 14. With this structure, the cable sheath can easily enter the crushing chamber 3 under the guidance of the arc surface of the arc-shaped guide shell 14. The two baffles are used to intercept the falling armor layer metal sheets, and the gap between the two baffles facilitates the feeding of the cable sheath.

[0026] In one embodiment, a guide hopper 18 is welded to the bottom of the casing 1, and the guide hopper 18 is connected to the crushing chamber 3 of the casing 1. With this structure, it is easy to discharge the crushed material.

[0027] In one embodiment, a plurality of arc blades are arranged around the crushing disc 17, and a mounting hole is provided at the center of the crushing disc 17. With this structure, the outer sheath of the cable extending between two adjacent arc blades can be cut and crushed. The mounting hole is used to connect to the output end of the second motor 16.

[0028] Working principle:

[0029] In operation, the wires and cables are first fed into the machine housing 1 through the feed inlet 12. Then, the first motor 4 is started, causing the transmission belt 13 at the output end of the first motor 4 to drive the lower cutter wheel 5 to rotate. During this process, the threaded rod 8 installed on the rotating support 7 pushes the lifting sleeve 9 downward through the shaft seat, and pushes the upper cutter wheel 6 in the mounting base 10 downward through the constant force spring 11, so that the gap between the lower cutter wheel 5 and the upper cutter wheel 6 matches the size of the wires and cables. During the transmission of the lower cutter wheel 5, the wires and cables are pulled into the machine housing 1, so that the annular cutter 20 set in the annular groove 19 of the lower cutter wheel 5 strips the wires and cables. At the same time, the arc-shaped guide shell 14 connects the stripping chamber 2 and the crushing chamber 3 of the machine housing 1. Furthermore, a discharge port 15 is opened on the upper inner side of the arc-shaped guide shell 14, and an observation port 22 is opened in the middle of the outer surface of the arc-shaped guide shell 14. As the annular cutter 20 of the lower cutter wheel 5 and the upper cutter wheel 6 strips the cable sheath, under the transmission action of the lower cutter wheel 5 and the upper cutter wheel 6, the cable sheath extends along the arc surface of the inner side of the arc-shaped guide shell 14 into the crushing chamber 3. Then, the second motor 16 is started to drive the crushing disc 17 to crush the cable sheath, and it falls into the outer side of the machine casing 1 through the guide hopper 18. During this process, the metal sheet of the inner armor layer of the cable is dispersed and discharged from the discharge port 15 under the action of gravity. The observation port 22 is set to facilitate the auxiliary guidance of the cable sheath, so that the cable sheath can accurately enter the crushing chamber 3 and pull the cable guide wire to the outside of the observation port 22.
