[0032] As Figure 1-6As shown in the figure, an embodiment of the present utility model provides a wire cutting device for use in a winding machine production, including a protective shell 1 and an electric cylinder 2 installed on the protective shell 1. A limiting plate 3 is fixedly installed inside the protective shell 1. The output end of the electric cylinder 2 penetrates through the inside of the limiting plate 3. A trapezoidal block 4 is fixedly installed at the output end of the electric cylinder 2. Limiting blocks 5 are fixedly installed on both sides of the trapezoidal block 4. Two symmetrically arranged sliding blocks 6 are slidably connected inside the limiting plate 3. Limiting grooves 7 adapted to the limiting blocks 5 are provided on the two sliding blocks 6. Clamping arms 8 are fixedly installed on the two limiting grooves 7. A fixed sleeve 10 is movably installed on one clamping arm 8, and a support block 11 is movably installed on the other clamping arm 8. The support block 11 and the fixed sleeve 10 are sleeved with each other. A blade 12 is fixedly installed inside the fixed sleeve 10. A wire clamping groove 13 is provided on the fixed sleeve 10. A placement groove 14 is provided inside the support block 11. A support groove 15 is provided on one side of the support block 11. The blade 12 is inserted into the placement groove 14.

Anti-collision pads are fixedly connected to the opposite sides of the two clamping arms 8. A protective pad is fixedly connected to the inner wall of the protective shell 1.

[0033] When cutting textile filaments, the two clamping arms 8 are in an open state at this time, and the piston rod of the electric cylinder 2 is in an extended state. The silk thread is attached to one side of the support groove 15. When the electric cylinder 2 is started to drive the piston rod to contract, during the process that the trapezoidal block 4 drives the limit block 5 to move, the limit block 5 drives the sliding block 6 to move through the restriction on the limit groove 7. The sliding block 6 slides in a direction perpendicular to the axial direction of the piston rod of the electric cylinder 2, driving the clamping arm 8 to move. The fixing sleeve 10 and the support block 11 approach and are sleeved with each other. The textile thread is clamped into the wire clamping groove 13. The wire clamping groove 13 and the support groove 15 fix the textile thread, and the textile thread is in a straightened state. The fixing sleeve 10 and the support block 11 continue to approach and are sleeved. The blade 12 cuts the textile thread and extends into the placement groove 14. The sponge 18 removes impurities on the surface of the blade 12. Then the electric cylinder 2 drives the clamping arm 8 to open, and the fixing sleeve 10 is separated from the support block 11.

By setting the sponge 18, when the blade 12 inserts into the placement groove 14 when cutting the wire material, it can simultaneously remove impurities on the surface of the blade 12, and the fixing sleeve 10 protects the blade 12 inside, preventing the blade 12 from being exposed outside and causing accidental contact and injury to personnel. By setting the elastic plate 16, when it is necessary to replace the fixing sleeve 10 and the support block 11, use a tool clamp to hold the stress rod 17, making the elastic plate 16 deform and approach each other, and then remove the elastic plate 16 from the installation groove 9 to complete the disassembly of the fixing sleeve 10, the support block 11 and the clamping arm 8. Then replace the fixing sleeve 10 and the support block 11 and install them through the installation groove 9 on the clamping arm 8, which is convenient for the quick disassembly of the fixing sleeve 10 and the support block 11.

[0034] In the technical solution provided by the present utility model, when cutting the textile filament, at this time, the two clamping arms 8 are in an open state, the piston rod of the electric cylinder 2 is in an extended state. The silk thread is attached to one side of the support groove 15. Start the electric cylinder 2 to drive the piston rod to contract. During the process that the trapezoidal block 4 drives the limit block 5 to move, the limit block 5 drives the sliding block 6 to move through the restriction of the limit groove 7. The sliding block 6 slides in a direction perpendicular to the axial direction of the piston rod of the electric cylinder 2, driving the clamping arm 8 to move. The fixed sleeve 10 and the support block 11 approach each other and are sleeved. The textile thread is clamped into the internal card wire groove 13. The card wire groove 13 and the support groove 15 fix the textile thread. The textile thread is in a straightened state. The fixed sleeve 10 and the support block 11 continue to approach and are sleeved. The blade 12 cuts the textile thread and extends into the internal placement groove 14. The sponge 18 removes the impurities on the surface of the blade 12. Then the electric cylinder 2 drives the clamping arm 8 to open, and the fixed sleeve 10 is separated from the support block 11. When it is necessary to replace the fixed sleeve 10 and the support block 11, use a tool clamp to hold the stress rod 17, so that the elastic plate 16 deforms and approaches each other. Then the elastic plate 16 is removed from the internal installation groove 9, completing the disassembly of the fixed sleeve 10, the support block 11 and the clamping arm 8. Then replace the fixed sleeve 10 and the support block 11 and install them through the internal installation groove 9 on the clamping arm 8.
