Description

Technical Field

[0001] The utility model relates to the technical field of sisal processing, in particular to a needle plate for producing high-strength composite sisal yarn. Background Art

[0002] The processing of sisal yarn generally goes through the following steps: sisal yarn is processed by a flax sorting machine, yarn is doubling by a drawing frame, and finally the burrs on the outside of the sisal yarn are removed by a shearing machine. In order to obtain high-strength sisal yarn, composite fibers are arranged inside the sisal yarn. The composite fibers can provide support for the sisal yarn. For example, the composite fibers are made of polypropylene fibers. Therefore, when producing high-strength sisal yarn, the needle plate on the drawing frame needs to be modified. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a needle plate for producing high-strength composite sisal yarn in view of the deficiencies of the above-mentioned prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A needle plate for producing high-strength composite sisal yarn comprises a needle plate strip, needle cores are evenly distributed on the needle plate strip, a threading needle core is arranged in the middle of the needle plate strip, a threading seat is processed on the threading needle core, and a threading hole is processed in the middle of the threading seat.

[0006] Furthermore, the threading needle core is detachably connected to the needle plate.

[0007] Furthermore, a mounting hole is processed in the middle of the needle plate strip, the threading needle core passes through the mounting hole, and the threading needle core is positioned by a step in the mounting hole. An external thread is processed around the bottom of the threading needle core, and the threading needle core is locked by a nut.

[0008] Furthermore, both ends of the threading hole are chamfered, and a plastic sleeve is arranged in the threading hole.

[0009] Furthermore, both ends of the needle strip are processed with connecting seats extending outwards, and connecting holes are opened on the connecting seats.

[0010] Compared with the prior art, the utility model provides a needle plate for producing high-strength composite sisal yarn, wherein a threading hole is provided on the middle needle core to facilitate the passing of composite fibers. When the composite fibers are combined on the drawing machine, the composite fibers are located in the center of the sisal yarn. At the same time, the needle core used for threading is detachable. When producing ordinary sisal yarn and high-strength sisal yarn, the needle core can be replaced to meet different production needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model;

[0012] Among them, 1. needle plate strip, 2. connecting seat, 3. connecting hole, 4. needle core, 5. threading needle core, 6. threading hole, 7. step, 8. hexagonal nut, 9. anti-loosening nut. DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0014] like Figure 1 As shown, a needle plate for producing high-strength composite sisal yarn includes a needle plate strip 1, connecting seats 2 extending outward are processed at both ends of the needle plate strip 1, and connecting holes 3 are opened on the connecting seat 2. The needle plate is fixed to the drawing machine as a whole at the connecting hole 3 by screws, and needle cores 4 are evenly distributed on the needle plate strip 1. The sisal fibers are combed by the needle cores to subdivide the sisal fibers. A threading needle core 5 is arranged in the middle of the needle plate strip 1, and a threading seat is processed on the threading needle core 5. A threading hole 6 is processed in the middle of the threading seat. The threading hole 6 is used to pass the fiber for composite with the sisal yarn, and the threading hole 6 is processed with chamfers at both ends, and a plastic sleeve is arranged in the threading hole 6. The chamfers and the plastic sleeve are arranged to prevent the composite fiber from being worn.

[0015] The threading needle core 5 is detachably connected to the needle plate 1, so that the threading needle core is used when producing high-strength sisal yarn, and the ordinary needle core can be used when producing ordinary sisal yarn. A mounting hole is processed in the middle of the needle plate strip 1, and the threading needle core 5 passes through the mounting hole. Steps are processed in the threading needle core 5 and the mounting hole, and the insertion depth of the threading needle core 5 is positioned by the steps. The bottom periphery of the threading needle core 5 is processed with an external thread, and the external thread locks the threading needle core 5 through a nut. The nut includes a hexagonal nut 8 and a lock nut 9. The hexagonal nut 8 locks the threading needle core 5, and the lock nut 9 can prevent the threading needle core 5 from loosening after being tightened.

[0016] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
