Description

Technical Field

[0001] This utility model relates to the field of waste wire and cable recycling and processing, and more specifically, to a waste cable and wire dismantling equipment. Background Technology

[0002] Currently, the common method for processing waste electrical wires is to use wire stripping machines to remove the insulation. Traditional wire stripping machines mostly use cutting blades to cut open the insulation, exposing the copper wire inside. Subsequent manual separation of the insulation and copper wire is still required. Furthermore, during operation, the wire may shift, resulting in incomplete cutting of the insulation and subsequent difficulty in separating the insulation and copper wire completely. In practical applications, due to the inconsistent sizes of wires / cables, the height of the cutting blades on the machine needs to be adjusted constantly to fit the wire / cable dimensions, leading to low work efficiency.

[0003] In addition, some wire stripping machines use a method of linking and lifting two sprockets simultaneously to accommodate wires or cables of different sizes; however, in actual use, this method requires lifting one sprocket first and then lifting the other sprocket via a chain, which causes greater wear and tear on the device.

[0004] Chinese patent CN112600135A discloses a wire stripping machine that uses a vertical anti-rotation slide bar on a movable plate to adjust the height of a circular cutting blade to change the cutting depth and accommodate variations in wire insulation thickness. However, it still requires operators to adjust the height of the circular cutting blade in real time, making operation somewhat inconvenient. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example

[0031] Please refer to Figure 1 and Figure 2 This application provides a waste cable and wire dismantling device, including two cutting units 1 and a support frame 2. The cutting units 1 are fixedly connected to the support frame 2 by bolts. Each cutting unit 1 has a drive spindle 3 and a cutting shaft 4 running through it. The drive spindle 3 and the cutting shaft 4 are arranged side by side inside the cutting unit 1. The front of the cutting unit 1 is provided with a fixed frame 5, and a slider 6 is provided on the fixed frame 5. The inner side of the fixed frame 5 is provided with a groove to accommodate the slider 6 sliding up and down. One end of the cutting shaft 4 passes through the slider 6, and the up and down sliding of the slider 6 synchronously drives the up and down movement of the cutting shaft 4.

[0032] It also includes a transmission gear set 7, which includes a main transmission gear 701, a secondary transmission gear 702, and a pair of auxiliary gears 703. The main transmission gear 701 is located at one end of the drive spindle 3 near the fixed frame 5, the secondary transmission gear 702 is located at one end of the cutting shaft 4 near the fixed frame 5, and the auxiliary gears 703 are fixed on the fixed frame 5 and mesh with the main transmission gear 701 and the secondary transmission gear 702 respectively. The top end of the drive spindle 3 is also provided with a transmission sprocket 704, and the two sets of cutting machine sets 1 are connected by a chain 14 installed on the transmission sprocket 704.

[0033] Please refer to Figure 6In this embodiment, the main drive gear 701 is fixed to the drive spindle 3, and the rotation of the drive spindle 3 drives the main drive gear 701 to rotate. The auxiliary drive gear 702 is fixed to the cutting shaft 4, driving the cutting shaft 4 to rotate. The main and auxiliary gears do not mesh with each other. The main drive gear 701 meshes with the lower auxiliary gear 703, while the auxiliary drive gear 702 meshes with the upper auxiliary gear 703. The two auxiliary gears 703 mesh with each other, meaning that when the main drive gear 701 rotates, it drives the auxiliary gear 703 to rotate, and the auxiliary gear 703 then drives the auxiliary drive gear 702 to rotate. This design ensures that the auxiliary drive gear 702 remains meshed with the upper auxiliary gear 703 as it slides up and down with the slider 6, thus ensuring that the cutting shaft 4 is always rotating.

[0034] Furthermore, the two auxiliary gears 703 are respectively connected to the support shaft 11. The center of the auxiliary gear 703 is provided with a ball bearing, which can ensure that the auxiliary gear 703 can rotate freely around the support shaft 11. The support shaft 11 is fixed to the fixing frame 5 by bolts.

[0035] Furthermore, a compression spring 12 is fixed to the top of the slider 6, and a limiting block 13 is provided at the other end of the compression spring 12. A screw is also provided directly above the slider 6, and the screw is fixed to the fixing frame 5. The limiting block 13 and the screw are threadedly connected. In actual use, the operator can adjust the position of the limiting block 13 on the screw to limit the upper limit height of the slider 6's sliding, thereby preventing the slider 6 from sliding too far upward and causing the secondary transmission gear 702 to disengage from the transmission gear set; the compression spring 12 plays a downward reset role for the slider 6.

[0036] Optionally, the size of the auxiliary gear 703 located above can be adapted to the actual situation. Combined with the height of the limit block 13 on the screw, it further ensures that the secondary transmission gear 702 and the auxiliary gear 703 always remain engaged during the up and down sliding of the slider 6.

[0037] Please refer to Figure 4 and Figure 5 In this embodiment, the drive spindle 3 is provided with several sets of feeding wheel sets 9, and the middle of the feeding wheel set 9 is provided with a groove 901; the cutting shaft 4 is provided with several sets of circular cutting blades 10, the circular cutting blades 10 are aligned with the groove 901, and the number of circular cutting blades 10 is the same as that of the feeding wheel sets 9.

[0038] Furthermore, the width of the grooves 901 in any set of feeding wheel groups 9 is different. Several feeding wheel groups 9 are arranged in order of increasing width of the grooves 901. This design facilitates the passage of wires or cables of different sizes. The cutting shaft 4 is equipped with circular cutting blades 10 of the same number and size as the feeding wheel groups 9, and the circular cutting blades 10 are aligned with the grooves 901 of the feeding wheel groups 9. During operation, the main shaft 3 is driven to rotate, which in turn drives the feeding wheel groups 9 to rotate, pushing the wires or cables into the cutting machine unit 1. While the main shaft 3 is rotating, it simultaneously drives the main drive gear 701 to rotate, which in turn drives the auxiliary gear 703 and the secondary drive gear 702 to rotate. The secondary drive gear 702 drives the cutting shaft 4, which in turn drives the circular cutting blades 10 to rotate. It can be seen that the main drive gear 701 and the secondary drive gear 702 rotate in opposite directions, so the rotation direction of the circular cutting blades 10 is opposite to the rotation direction of the feeding wheel groups 9. This allows for better cutting of the outer sheath of the wires or cables.

[0039] Furthermore, since most wires or cables are cylindrical and vary in size, when cutting larger cables, one end of the cable, after entering the groove 901 of the feeding wheel, will compress the circular cutting blade 10 and lift it upwards, thereby lifting the cutting shaft 4 upwards. The cutting shaft 4, due to the action of the slider 6, can slide freely up and down, so there will be no wire jamming during the entire cutting process. For cutting wires or cables of different sizes, the slider 6, under the action of gravity and the reset effect of the compression spring 12, will also compress downwards accordingly. This ensures that the circular cutting blade 10 also exerts a compressive force on the wire or cable during operation, preventing it from bouncing back and forth, thus ensuring the smoothness of the cutting process.

[0040] It should be noted that there are certain requirements for the selection of compression spring 12 here. Springs with excessively high elastic coefficients should not be selected, otherwise the slider 6 may not be able to slide upwards. The staff can make an appropriate selection based on the actual situation, and will not elaborate further.

[0041] Furthermore, the side wall of the cutting unit 1 is provided with several feeding ports 15 of different diameters. The feeding ports 15 are arranged in order of diameter, and each feeding port 15 corresponds to the position of the feeding wheel group 9, so that after the wire is inserted into the feeding port 15, it can be directly inserted into the groove 901 of the feeding wheel group 9.

[0042] Please refer to Figure 3In some embodiments of this utility model, in one set of cutting machine units 1, the end of the drive spindle 3 away from the fixed frame 5 is also provided with a main sprocket 16. The support frame 2 is equipped with a drive motor (not shown in the drawings), and the output shaft of the drive motor is connected to a transmission shaft 8. The end of the transmission shaft 8 extending out of the support frame 2 is provided with a secondary sprocket 17. The main sprocket 16 and the secondary sprocket 17 are connected by a chain 14. Both the drive spindle 3 and the cutting shaft 4 are provided with rollers 18, and in the two sets of cutting machine units 1, the drive spindle 3 and the cutting shaft 4 are arranged in opposite directions.

[0043] In actual use, the drive unit is started, which drives the secondary sprocket 17 to rotate, which in turn drives the main sprocket 16 to rotate. The main sprocket 16 then drives the drive spindle 3 to rotate, and the entire cutting unit 1 begins to operate. It can be seen that during the rotation of the drive spindle 3, the sprocket located in front of the fixed frame 5 also begins to rotate, which in turn drives the other cutting unit 1 to start operating. The two sprockets rotate in the same direction, and the two drive shafts are located above and below the wire or cable respectively, rotating in opposite directions, ensuring that the wire or cable always moves in one direction. In this embodiment, in the other cutting unit 1, the drive spindle 3 and the cutting shaft 4 are in opposite vertical directions, allowing for the cutting of the other side of the wire or cable, making the cutting process more comprehensive. After one cut is completed, the wire or cable can be crushed by the grinding wheels 18 on the drive spindle 3 and the cutting shaft 4, facilitating better separation of the internal metal wires and the outer shell of the wire or cable.

[0044] Furthermore, the back of the cutting unit 1 is also provided with a slider 6 for supporting the cutting shaft 4 or the drive spindle 3. This ensures that the cutting shaft 4 or the drive spindle 3 will not have a large angular deviation during the up-and-down sliding process of following the slider 6, which would cause the circular cutting disc to get stuck in the groove 901 of the feeding wheel group 9.

[0045] In summary, the embodiments of this utility model provide a waste cable and wire dismantling device, which, by setting two sets of cutting units 1, can cut the wires or cables simultaneously from both the top and bottom, making the cutting more thorough;

[0046] By setting up the transmission wheel set 7, only one drive shaft 3 needs to be driven to drive the entire device, making it more practical.

[0047] By setting up a slider 6 that can slide up and down, a limiting component, and a compression spring 12, the circular cutting blade 10 can be prevented from jumping back and forth when cutting wires or cables of different sizes, ensuring the smoothness of the cutting process.
