Description

Technical Field

[0001] The utility model relates to a wire drawing device, belonging to the technical field of textile. Background Art

[0002] Chemical fiber filaments are one of the indispensable materials in human life, and various articles used in human daily life can be made by processing them. The manufacture of chemical fiber filaments usually involves first making a spinning melt or solution from natural or synthetic macromolecular substances or inorganic substances, then filtering and metering, and extruding it through a spinneret or spinneret plate to form a liquid stream and then solidifying it into fibers. Then, after processing such as stretching and heat setting of the fibers, chemical fiber filaments can be obtained. During the production process of chemical filaments, wire drawing operations are often required for chemical filaments. In current wire drawing operations, for example, a chemical fiber wire drawing device disclosed in the existing literature (CN214881965U) synchronously draws wires through multiple rotating shafts on a workbench. However, after the wire drawing is completed, the wire coils still need to be placed on a wire rack for standby. Obviously, this reduces the work efficiency to a certain extent. Content of the Utility Model

[0003] Based on the above, the utility model provides a wire drawing device on a wire rack to overcome the deficiencies of the prior art.

[0004] The technical solution of the utility model is: a wire drawing device, comprising:

[0005] A frame unit, including a bracket and a cross beam. A plurality of the cross beams are arranged at intervals from top to bottom between the brackets, and a cavity is provided inside the cross beam along its length direction;

[0006] A wire drawing unit, including a driving shaft, a main bevel gear, a driven shaft, a driven bevel gear, a wire roller and a driving mechanism. The driving shaft is rotatably installed in the cavity. The main bevel gears are arranged at intervals along the length direction on the driving shaft. The driven shafts are rotatably installed on both sides of the cross beam at intervals along the length direction. The driven bevel gears are installed at the inner ends of the driven shafts and mesh with the main bevel gears. The wire rollers are detachably installed at the outer ends of the driven shafts. The driving mechanism is connected to the driving shaft.

[0007] In one example, a machine box is provided on the side of one of the brackets, and the corresponding end of the driving shaft extends into the machine box. The driving mechanism includes a motor and a transmission belt. The main shaft of the motor is located inside the machine box, and the transmission belt is installed between the main shaft and the driving shaft, and between two driving shafts.

[0008] In one example, the cross beam is provided with wire guides at intervals. The wire guide includes a support rod, a cross bar and a wire loop. The support rod is arranged on the cross beam. The cross bar is arranged on both sides of the support rod. The wire loop is arranged at the end of the cross bar.

[0009] In one example, the driven shaft is mounted on both sides of the cross beam in an upwardly inclined posture.

[0010] In one example, a plug-in groove is provided at the outer end of the driven shaft, and the wire roller is plugged into the plug-in groove.

[0011] The beneficial effects of the present utility model are as follows: By directly integrating the wire drawing unit on the wire rack, the step of moving the wire coil to the wire rack in the traditional wire drawing equipment is omitted, significantly improving the production efficiency and the continuity of the work process; The configuration of multiple driving shafts, driven shafts, driving bevel gears and driven bevel gears realizes the inclined installation of the wire rollers, which helps to ensure the stability of the device operation; In addition, with the synchronous driving mechanism of the motor and the transmission belt, the uniform and synchronous rotation of multiple wire rollers can be achieved, improving the consistency of wire drawing and the quality of the product.
