[0023] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-7As shown, the wire package cutting machine includes a frame 1 and a controller. The frame 1 is provided with a feeding mechanism 2 connected to the controller, a material moving mechanism 3, a clamping mechanism 4, and a cutting mechanism 5. The material moving mechanism 3 receives the output end of the feeding mechanism 2 and can move the wire package to the clamping mechanism 4. The cutting mechanism 5 can cooperate with the clamping mechanism 4 to cut the wire package.

[0025] The material transfer mechanism 3 transfers the wire package at the feeding mechanism 2 to the clamping mechanism 4, the clamping mechanism 4 fixes the wire package to be cut, and the cutting mechanism 5 cooperates with the clamping mechanism 4 to cut the wire package. The present invention has a high degree of automation, can reduce manual single repetitive work, reduce work intensity, and improve work efficiency.

[0026] The feeding mechanism 2 includes a material channel 6, a pushing drive 7 that is movably arranged in the material channel 6 to push the material at a fixed length, and a detection device that cooperates with the pushing drive 7 to detect the arrival of the wire package at the output end of the material channel 6. The controller can control the operation of the material moving mechanism 3 according to the signal transmitted by the arrival detection device.

[0027] When loading, the wire packages are first arranged in sequence in the material channel 6, and the push drive 7 moves a fixed length in the material channel 6, such as pushing a fixed length distance to the output end of the material channel 6 each time, so as to push the wire packages in the material channel 6 to the output end one by one. In order to achieve accurate loading of the wire packages, an in-place detection device is set in the loading mechanism 2. The in-place detection device detects and feeds back a signal of whether the wire package at the output end of the material channel 6 is in place, and transmits the signal to the controller. After receiving the signal, the controller controls the material transfer mechanism 3 to work, and transfers the wire package at the output end of the material channel 6 to the clamping mechanism 4.

[0028] The in-position detection device comprises a push rod 8 and a detection probe 9 arranged on the push drive 7 , a first elastic member 10 is arranged between the push rod 8 and the push drive 7 , and the detection probe 9 is used to sense the position of the push rod 8 .

[0029] Specifically, when the wire packages in the material channel 6 are arranged compactly and pushed toward the output end of the material channel 6, the pushing drive 7 drives the pushing rod 8 and the detection probe 9 to move at a fixed length, the pushing rod 8 compresses the first elastic member 10, and the moving distance of the pushing rod 8 is less than the fixed-length moving distance of the pushing drive 7. At this time, the detection probe 9 detects the change in the position of the pushing rod 8, and the material moving mechanism 3 works to transfer the wire packages at the output end to the clamping mechanism 4.

[0030] Since the thickness of wire packages of different specifications and models may be different, the distance difference after pushing several wire packages will accumulate, which will cause the wire packages in the material channel 6 to be arranged in a non-compact manner. At this time, the pushing drive 7 drives the pushing rod 8 and the detection probe 9 to move at a fixed length, and the pushing rod 8 does not compress the first elastic member 10. The distance moved by the pushing rod 8 is equal to the fixed-length moving distance of the pushing drive 7. The detection probe 9 does not detect the change in the position of the pushing rod 8, and the material moving mechanism 3 does not work. Subsequently, the pushing drive 7 continues the next fixed-length movement, and so on, until the detection probe 9 detects the change in the position of the pushing rod 8.

[0031] The setting of the in-place detection device can realize the accurate feeding of the wire package, and timely correct the distance difference in the wire package pushing process, so that wire packages of different models can be sent out through the material transfer mechanism 3. It has a reasonable structure, ingenious design and strong versatility.

[0032] The first elastic member 10 can be a spring disposed between the push rod 8 and the push drive 7, or other elastic members existing in the prior art, which are not limited here. The provision of the first elastic member 10 can prevent the push rod 8 from rigidly acting on the wire package and damaging the product.

[0033] Specifically, the push drive 7 is provided with a mounting hole for the push rod 8 to pass through, and the push rod 8 includes a T-shaped rod body and a push block detachably connected to the rod body. During assembly, the rod body is first passed through the mounting hole, and then the spring is sleeved on the push rod 8, and finally, the push block is installed at the end of the rod body. At this time, one end of the spring is connected to the push rod 8, and the other end is connected to the push drive 7.

[0034] like Figure 5 , Figure 6 As shown, the material moving mechanism 3 includes a material moving plate 11 with an opening, and a material moving drive 12 for driving the material moving plate 11 to move. A magnetic attraction member 13 for positioning the wire package is provided on the side of the opening.

[0035] In order to enhance the universality and adapt to the positioning of wire packages with different inner diameters, the opening is configured as a V-shaped opening.

[0036] A magnetic block 14 may be provided in the V-shaped opening, wherein the magnetic attraction of the magnetic block 14 is greater than the magnetic attraction of the magnetic element 13, so that wire packages of different inner diameters can be closely attached to the V-shaped opening. To prevent the wire package from escaping from the opening, the end of the opening is bent inward to form an anti-slip hook 15.

[0037] like Figure 7As shown, the clamping mechanism 4 includes a first positioning rod 16, a second positioning rod 17, a first rotation drive 18 connected to the first positioning rod 16, and a clamping drive 19 that drives the first positioning rod 16 and the second positioning rod 17 to move closer or farther away. An outer protrusion and an inner recess are provided between the first positioning rod 16 and the second positioning rod 17, and one of the outer protrusion and the inner recess is provided on the first positioning rod 16, and the other is provided on the second positioning rod 17.

[0038] When the material transfer mechanism 3 sends the wire package out, the second positioning rod 17 is inserted into the center of the wire package, and the clamping drive 19 drives the first positioning rod 16 and the second positioning rod 17 to approach each other to achieve clamping and fixing of the wire package. When the cutting mechanism 5 is working, the first rotary drive 18 drives the wire package to rotate and contact the cutting mechanism 5 to achieve rotary cutting.

[0039] like Figure 2 As shown, the cutting mechanism 5 includes a mounting block 20, a cutter device 21 slidably arranged on the mounting block 20, and a translation drive 22 connected to the mounting block 20. A second elastic member 23 is provided between the cutter device 21 and the mounting block 20. The translation drive 22 can drive the cutter device 21 to approach the clamping mechanism 4 and elastically abut against the wire package on the clamping mechanism 4.

[0040] The cutter device 21 is slidably set on the mounting block 20. The second elastic member 23 between the cutter device 21 and the mounting block 20 can make the cutter device 21 elastically abut against the wire package. This elastic abutment method effectively compensates for the concentricity problem and can achieve the cutting of wire packages of various specifications and models with different inner diameters without constantly replacing the cutting slices. It has strong versatility and high work efficiency.

[0041] The cutter device 21 may be a circular cutter or a sawtooth cutter driven by a second rotary drive, which is not limited here.

[0042] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
