Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gauze processing equipment, specifically a traction device for gauze processing. Background Technology
[0002] Gauze is widely used in the medical field. Medical gauze is usually square-shaped and is generally made of thin gauze folded and sewn in multiple layers. For easy handling, fabric carrying straps are usually inserted during folding. The production process of medical gauze involves unwinding, cutting, multi-layer sewing, folding, and stacking. Each of these steps—cutting, multi-layer sewing, folding, and stacking—requires a traction device to move the gauze to one side, coordinating with other equipment or manual labor to complete the corresponding processes, thereby improving the production efficiency of medical gauze. Traditional traction devices have simple conveyor roller structures, which can easily lead to partial slack and entanglement of the gauze during transport. Furthermore, the gauze is prone to lateral movement on the conveyor rollers, significantly reducing the stability of the gauze traction process and causing misalignment in the cutting and sewing steps, thus affecting both production efficiency and quality.

Detailed Implementation
[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] Please refer to Figures 1 to 5 The present invention relates to a traction device for gauze processing, comprising a traction table 1, a traction component, a guide component, and a tensioning component.
[0025] The traction platform 1 is a rectangular plate structure, which is supported on the ground by support legs. The guiding assembly includes two guide rollers 5, which are rotatably arranged above the traction platform 1. The two guide rollers 5 are parallel and spaced a certain distance apart. The yarn 4 to be pulled is pulled out from the yarn roll or upstream equipment, and the yarn 4 to be pulled extends to the top of the traction platform 1 and is supported on the two guide rollers 5.
[0026] The tensioning assembly includes a tensioning bracket 6, a tensioning shaft 7, and a tensioning roller 8. The tensioning bracket 6 is fixed on the traction table 1 and located between the two guide rollers 5. The tensioning bracket 6 includes two supporting vertical beams and a supporting horizontal beam. The lower ends of the two supporting vertical beams are respectively fixed to both sides of the traction table 1, and the two ends of the supporting horizontal beam are connected to the upper ends of the two supporting vertical beams. The tensioning shaft 7 is connected to the lower part of the tensioning bracket 6 through an elastic element. The tensioning shaft 7 can move within a certain range along the vertical direction of the tissue. The tensioning roller 8 is rotatably sleeved on the tensioning shaft 7, and the tensioning roller 8 presses down on the gauze 4 to be pulled.
[0027] The traction assembly includes two traction support plates 21, an active traction roller, a driven traction roller 2, and a drive mechanism. The two traction support plates 21 are fixed on the traction table 1. The active traction roller (not shown in the figure) and the driven traction roller 2 are rotatably disposed between the two traction support plates 21. The end of the active traction roller is connected to the drive mechanism. In this embodiment, the drive mechanism is a drive motor 3, which is fixed on one of the traction support plates 21.
[0028] The yarn 4 to be pulled passes through the gap between the active traction roller and the driven traction roller 2, and the active traction roller and the driven traction roller 2 press the yarn 4 to be pulled. The drive motor 3 is used to drive the active traction roller to rotate, so that the active traction roller drives the driven traction roller 2 to rotate synchronously in the opposite direction through friction, thereby causing the two to pull the yarn continuously through clamping friction. The tension roller 8 provides elastic clamping force to the yarn under the pressure of the components, so that the yarn is fully tensioned during the pulling process, preventing the yarn from tangling due to local slack.
[0029] In a preferred embodiment, both the active traction roller and the driven traction roller 2 have a friction layer made of rubber on their surfaces. The friction layer is used to increase the friction between the active traction roller and the driven traction roller 2 and the yarn, and to prevent the yarn from slipping.
[0030] In a preferred embodiment, both guide rollers 5 are provided with guide grooves 51 on their surfaces. The width of the guide grooves 51 is equal to the width of the yarn 4 to be pulled. The yarn 4 to be pulled is confined within the guide grooves 51. The guide grooves 51 can ensure that the yarn will not shift laterally during the pulling process, thereby improving the stability of the yarn being pulled.
[0031] In a preferred embodiment, the lower end of the support beam of the tensioning bracket 6 is provided with two lifting plates 61, each lifting plate 61 is provided with a lifting groove 62, the lifting groove 62 passes through the lifting plate 61 it is located in, the two ends of the tensioning shaft 7 are respectively limited to the two lifting grooves 62, each lifting groove 62 is provided with an elastic element, the elastic element is preferably a helical spring 63, the lower end of the elastic element abuts against the end of the tensioning shaft 7, and the upper end abuts against the top of the lifting groove 62, so that the elastic element presses the tensioning shaft 7 downward through the elastic force, thereby enabling the tensioning roller 8 to press the gauze between the two guide rollers 5.
[0032] In a preferred embodiment, both the top of the slide groove and the end of the tensioning shaft 7 are provided with limiting posts, and the upper and lower ends of the helical spring 63 are respectively sleeved on the limiting posts, which can prevent the helical spring 63 from falling off.
[0033] In a preferred embodiment, the tensioning shaft 7 is further provided with two limiting sleeves 71, which are respectively sleeved on both sides of the tensioning roller 8. Each of the two limiting sleeves 71 has a limiting pin 72 on its outer side, and the two limiting pins 72 pass through the tensioning roller 8. The limiting pins 72 and the limiting sleeves are used to prevent the tensioning roller 8 from moving along its axial direction on the tensioning shaft 7.
[0034] In a preferred embodiment, the drive motor 3 is connected to the mounting base 31 via a fixed connecting rod. The mounting base 31 is fixed to the outside of the traction support plate 21 by bolts. One end of the active traction roller passes through the outside of the support plate where the drive motor 3 is located, and this end of the active traction roller is connected to the output shaft of the drive motor 3 via a coupling.
