Description

Technical Field

[0001] The utility model relates to the technical field of glove knitting machine components, and more particularly to a needle plate scissors assembly. Background Art

[0002] Glove knitting machines require the ability to cut the yarn involved in knitting. Existing glove knitting machines use a thread-cutting mechanism on the upper surface of the needle plate to cut the yarn. A hook knife extends, grabs the yarn, and pulls it back. The yarn is then cut by scissors, and finally, the hook knife and clamp block clamp the cut thread ends. Because the hook knife and clamp block are made of metal with a relatively smooth surface, they cannot effectively clamp the thread ends, causing them to fall off. Utility Model Content

[0006] Furthermore, the hook knife includes a blade body and a blade head, the blade head is located at the upper end of the blade body, and a blade is provided at the lower part of the blade head.

[0007] Furthermore, a clamping block is provided on one side of the mounting plate close to the hook knife, and the protrusion is provided on the side of the clamping block.

[0008] Furthermore, the protrusion and the clamping block are integrally formed.

[0009] Furthermore, a clip is provided between the mounting plate and the hook knife, a notch is provided on the clip, and a part of the protrusion is provided through the notch.

[0010] Furthermore, a groove is provided on one side of the mounting plate close to the clip, and the clip block is inserted into the groove.

[0011] Furthermore, the protrusion and the clamping block are made of rubber.

[0012] The beneficial effect of the utility model is that, through the arrangement of the protrusion, the thread end can be effectively clamped after the hook knife and the auxiliary scissors cooperate to cut the thread. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] As attached Figure 1 -Attached Figure 4 The figure shows a needle plate scissors assembly comprising several positioning blocks 2 mounted on a needle plate 1. A slot is formed between adjacent positioning blocks 2. A hook knife 5 and a mounting plate 3 are mounted within the slot. The mounting plate 3 is fixedly mounted within the slot, and the hook knife 5 slides within the slot. A secondary shear 4 is mounted on the upper portion of the positioning blocks 2, near one side of the hook knife 5. The upper end of the secondary shear 4 is angled to form a cutting edge. A protrusion 11 is fixedly mounted on the side of the mounting plate 3 near the hook knife 5. The hook knife 5 comprises a blade 6 and a head 7. The head 7 is located at the upper end of the blade 6. A blade 8 is disposed at the lower end of the head 7, which engages with the upper end of the secondary shear 4. When the hook knife 5 moves downward, the blade 8 and the secondary shear 4 cut the thread passing between them. Because the lower end of the head 7 near the blade 8 is lower than the lower end, the thread is bent during cutting, causing the cut thread to be located between the head 7 and the clamping piece 9, where it is clamped by the head 7 and the protrusion 11. By cooperating with the cutter head 7 and the auxiliary scissors 4, the thread is hooked and cut off, which can reduce the residual thread ends on the gloves, reduce the subsequent processing of the gloves, and make the gloves more beautiful in appearance.

[0020] Furthermore, a clamping block 13 is provided on the side of the mounting plate 3 near the hook blade 5, and a protrusion 11 is provided on the side of the clamping block 13. A clip 9 is provided between the mounting plate 3 and the hook blade 5, and a notch 10 is provided on the clip 9. A portion of the protrusion 11 is provided through the notch 10. A groove 12 is provided on the side of the mounting plate 3 near the clip 9, and the clamping block 13 is inserted into the groove 12. The clamping block 13 is clamped between the clip 9 and the mounting plate 3, allowing the mounting plate 3 to tilt toward the cutter head 7, thereby reducing the gap between the clip 9 and the cutter head 7. The clip 9 and the cutter head 7 cooperate to more firmly clamp the thread at the rear of the thread end.

[0021] Furthermore, the projection 11 and the clamping block 13 are integrally formed, and the projection 11 and the clamping block 13 are made of tendon material and are made of rubber. The projection 11 made of tendon material can cooperate with the cutter head 7 to clamp the thread end more firmly.

[0022] Furthermore, the height of the upper end of the cutter head 7 exceeds the height of the upper end of the auxiliary scissors 4, and the projection of the upper end of the auxiliary scissors 4 is located within the range of the protrusion 11. After the blade 8 and the upper end of the auxiliary scissors 4 cooperate with each other to cut the thread, the thread end falls within the range of the protrusion 11, thereby clamping the thread end through the interaction between the cutter head 7 and the protrusion 11.

[0023] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
