DETAILED DESCRIPTION

[0022] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] Example 1

[0024] A wire and cable chipper, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base plate 1, a fuselage 2, a protective cover 3, a motor 4, a cutting shaft 5, a first gear 6, a cylinder 7, a pushing component and a splitting component. The base plate 1 is bolted with the fuselage 2, the protective cover 3 is bolted to the rear side of the fuselage 2, the motor 4 is bolted to the right side of the protective cover 3, two cutting shafts 5 are connected in the protective cover 3 through bearings, the upper cutting shaft 5 is connected to the output shaft of the motor 4 through a coupling, the right part of the cutting shaft 5 is keyed with the first gear 6, the two first gears 6 are meshed with each other, three cylinders 7 are connected to the protective cover 3, the cutting shafts 5 all pass through the cylinders 7, the cylinders 7 are provided with a pushing component, the pushing component can push the wires and cables to move forward, the cylinder 7 is provided with a splitting component, the splitting component can perform secondary cutting on the wires and cables.

[0025] When using the device, the staff starts the motor 4, and the output shaft of the motor 4 rotates to drive the upper cutting shaft 5 to rotate. Under the action of the first gear 6, the lower cutting shaft 5 rotates accordingly. Then the staff extends the wires and cables to be chipped into the cylinder 7, and performs preliminary cutting on the wires and cables by the rotating cutting shaft 5. Then, the pushing component pushes the wires and cables forward in the cylinder 7, and then performs secondary cutting through the splitting component. When the cutting is completed, the staff turns off the motor 4.

[0026] like Figure 4 , Figure 5 and Figure 6 As shown, the pushing assembly includes a rotating shaft 8, a cam 9, a second gear 10 and a first belt 11. Two rotating shafts 8 are connected between the middle parts of the three cylinders 7 through bearings. Three cams 9 are connected to the rotating shafts 8 with keys. The cams 9 are all located in the cylinders 7. The left part of the rotating shaft 8 is connected with a second gear 10 with keys. The two second gears 10 are meshed with each other. The first belt 11 is connected between the upper cutting shaft 5 and the right part of the upper rotating shaft 8 through a pulley.

[0027] When the device is used, the cutting shaft 5 rotates through the first belt 11 to control the rotation of the upper rotating shaft 8. Under the action of the second gear 10, the lower rotating shaft 8 will also rotate. When the rotating shaft 8 rotates, it drives the cam 9 to rotate. The rotation of the cam 9 pushes the wires and cables in the cylinder 7 forward for secondary cutting.

[0028] like Figure 4 and Figure 5 As shown, the splitting assembly includes a splitting shaft 12, a second belt 121, a third gear 122 and a conical cylinder 17. Two splitting shafts 12 are connected to the front of the three cylinders 7 through bearings. The second belt 121 is connected to the right part of the upper rotating shaft 8 through a pulley. The left part of the splitting shaft 12 is key-connected to the third gear 122. The two third gears 122 are meshed with each other. The front of the cylinder 7 is connected to a conical cylinder 17.

[0029] When using the device, when the rotating shaft 8 rotates, the upper dividing shaft 12 is controlled to rotate by the second belt 121. Under the action of the third gear 122, the lower dividing shaft 12 will also rotate. The cam 9 pushes the cut wires and cables through the conical cylinder 17 to gather them and then transport them to the dividing shaft 12. The rotating dividing shaft 12 performs secondary cutting to cut the thinner insulating skin inside.

[0030] Example 2

[0031] On the basis of Example 1, Figure 1 and Figure 7 As shown, it also includes a sliding frame 13, a push plate 14, a rubber sleeve 16 and a spring 15. The sliding frame 13 is slidably connected to the front part of the fuselage 2. The push plate 14 is welded to the rear part of the sliding frame 13. The push plate 14 is located in the fuselage 2. The rubber sleeve 16 is connected to the middle position of the front part of the sliding frame 13. Springs 15 are connected between the left and right parts of the sliding frame 13 and the fuselage 2.

[0032] When using the device, the wires and cables after cutting fall out from the front end of the cylinder 7 and fall on the fuselage 2. The staff holds the rubber sleeve 16 and pulls the sliding frame 13 to slide forward. The spring 15 is deformed, and the sliding frame 13 slides forward to drive the push plate 14 to move forward, thereby pushing the wires and cables on the fuselage 2 forward. After pushing them out, the sliding frame 13 is released. Under the action of the spring 15 returning to its original position, the sliding frame 13 drives the push plate 14 to move backward and return to its original position.

[0033] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
