Description

Technical Field

[0001] This utility model relates to the technical field of automatic edge alignment and positioning devices for textile machines, and in particular to an automatic edge alignment and positioning device for textile machines. Background Technology

[0002] The existing patent publication number (CN221836393U) discloses an infrared sensing calibration edge alignment device for composite fabrics, including a processing device, a slide block, and a base. The base is fixedly connected to one side of the processing device. Two sets of symmetrically designed slide rails are installed at the top of the base. The slide block is slidably installed at the top of the slide rails. Two sets of rotating rollers are symmetrically installed at the top of the slide block. A support frame is fixedly installed on the side of the slide block near the processing device. A rectangular groove is opened on one side of the support frame. A bidirectional screw is rotatably installed in the rectangular groove. An infrared detector detects the composite fabric passing below it, and then controls the slide block to move left and right on the slide rails according to the detection result, realizing automatic edge alignment of the composite fabric roll, so that the composite fabric roll always remains neat and orderly. This equipment has a high degree of automation, improves the production efficiency of composite fabrics, and ensures product quality.

[0003] However, since the two ends of the paper tube used for rewinding are in frictional contact with the limiting plate, it will cause vibration at both ends and affect the positioning accuracy of the opposite edge. Furthermore, as the paper tube is continuously rewound, the thickness of the fabric accumulates and the axial height of the paper tube will gradually increase. At this time, its two ends not only have rolling contact with the limiting plate but also straight contact. This compound dry friction will greatly affect the neatness of the opposite edge.

[0004] Based on the patented technology, some structural components were improved. Utility Model Content

[0005] An automatic edge alignment and positioning device for a textile machine includes a textile rewinding machine and two edge alignment adjusting arms. One end of each edge alignment adjusting arm is threadedly connected to a bidirectional screw. An automatic adjusting sleeve is provided at the outer end of each edge alignment adjusting arm. A sliding arm is slidably mounted inside the automatic adjusting sleeve. A rubber turntable is rotatably mounted at the lower end of each sliding arm. The rubber turntable abuts against both ends of the textile rewinding paper tube. When the textile rewinding paper tube is placed on a rotating roller and rotates under the rolling motion of the roller, it drives the rubber turntable to rotate synchronously. The sliding arm limits the lateral position of the textile rewinding paper tube to ensure that it is aligned with the edge of the fabric for winding.

[0006] Preferably, the end of the rubber turntable pointing towards the textile rewinding paper tube has a conical structure, which facilitates the use of paper tubes of different specifications. It should be noted that the inner diameter of the textile rewinding paper tube is not greater than the bottom circle diameter of the conical structure of the rubber turntable and not less than the top circle diameter of the rubber turntable.

[0007] Preferably, the sliding arm is provided with a through counterweight reserved slot, and a counterweight is disposed in the counterweight reserved slot.

[0008] Preferably, the counterweight is magnetically fixed in the pre-reserved slot of the counterweight, and the left and right end faces of the counterweight do not extend beyond the left and right end faces of the sliding arm. This facilitates the smooth up-and-down sliding of the sliding arm within the automatic adjusting sleeve. After the counterweight is configured, a certain weight is added to form a certain downward pressure, which presses the textile rewinding paper tube onto the rotating roller, thus improving the tightness of the wound fabric.

[0009] Preferably, the automatic adjusting sleeve is coated with grease, which facilitates the smooth sliding of the sliding arm relative to the automatic adjusting sleeve.

[0010] The advantages and positive effects of this utility model are:

[0011] 1. Based on existing technology, the limiting plate structure is scientifically improved. A conical rubber turntable is placed against the two ends of the textile rewinding paper tube. The rubber turntable rotates with the textile rewinding paper tube, which effectively improves the limiting accuracy of the two opposite side structures on the textile rewinding paper tube. In addition, a counterweight is provided to provide a certain adjustable downward pressure, so that the fabric can be wound more tightly and the rewinding effect is better.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0017] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0018] like Figure 1 As shown, the automatic edge alignment and positioning device for a textile machine according to this utility model includes a textile rewinding machine 10. The main structure of the textile rewinding machine 10 is consistent with the prior art (CN221836393U). The difference is that the embodiment of this application includes two edge alignment adjustment arms 16. One end of the edge alignment adjustment arm 16 is threadedly connected to a bidirectional screw 15. An automatic adjustment sleeve 17 is provided at the outer end of the edge alignment adjustment arm 16. A sliding arm 18 is provided inside the automatic adjustment sleeve 17 and slides up and down. A rubber turntable 19 is rotatably provided at the lower end of the sliding arm 18. The rubber turntable 19 abuts against both ends of the textile rewinding paper tube 14. When the textile rewinding paper tube 14 is placed on the rotating roller 13 and rotates under the rolling motion of the rotating roller 13, it drives the rubber turntable 19 to rotate synchronously. The sliding arm 18 limits the lateral position of the textile rewinding paper tube 14 to ensure that it is aligned with the edge of the fabric for winding.

[0019] Preferably, the end of the rubber turntable 19 pointing towards the textile rewinding paper tube 14 has a conical structure, which facilitates the use of paper tubes of different specifications. It should be noted that the inner diameter of the textile rewinding paper tube 14 is not greater than the bottom circle diameter of the conical structure of the rubber turntable 19 and not less than the top circle diameter of the rubber turntable 19.

[0020] Preferably, the sliding arm 18 is provided with a through counterweight reserved slot 20, and a counterweight 21 is disposed in the counterweight reserved slot 20.

[0021] Preferably, the counterweight 21 is magnetically fixed in the counterweight reserved groove 20, and the left and right end faces of the counterweight 21 do not exceed the left and right end faces of the sliding arm 18. This facilitates the smooth up and down sliding of the sliding arm 18 within the automatic adjusting sleeve 17. After the counterweight 21 is configured, a certain weight is added to form a certain downward pressure, which presses the textile rewinding paper tube 14 onto the rotating roller 13. This helps to improve the tightness of the wound fabric.

[0022] Preferably, the automatic adjusting sleeve 17 is coated with grease, which facilitates the smooth sliding of the sliding arm 18 relative to the automatic adjusting sleeve 17.

[0023] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
