Pay-off device for textile machine

Abstract

According to the pay-off device for the textile machine, the transverse sliding groove is formed in the side of the supporting rotating shaft, the compression spring is arranged in the transverse sliding groove, and the baffle of the pressing mechanism is slidably arranged in the transverse sliding groove through the compression spring. In addition, the supporting rotating shaft is located in a space formed by a baffle, an upper clamping plate and a lower clamping plate in the pressing mechanism, and the baffle, the upper clamping plate and the lower clamping plate further abut against the yarn on the supporting rotating shaft. Thus, when the supporting rotating shaft pulls the yarn outwards in a rotating mode, the yarn pressing mechanism can be attached to the yarn all the time, and therefore the situation that the yarn is disordered due to looseness in the yarn paying-off process can be effectively prevented.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 3 As shown, the pay-off device for a textile machine provided in the embodiment of the present application includes a base 100, a support plate 200, a support shaft 300 and a clamping mechanism, wherein the base 100 is a bearing mechanism of the pay-off device, and a support plate 200 is provided at the top of the base 100, and the base 100 and the support plate 200 are in a mutually perpendicular relationship. Specifically, two support plates 200 may be provided at the top of the base 100, and the two support plates 200 are symmetrically arranged at the top of the base 100. A support shaft 300 is vertically provided on the outer surface of each support plate 200, and the support shaft 300 is rotatably connected to the support plate 200, that is, the support shaft 300 can rotate relative to the support plate 200.

[0027] In actual use, the yarn can be directly wound onto the support shaft 300, and then the pay-off process can be realized by cooperating with the textile equipment. In addition, the bobbin wound with the yarn can be fixedly arranged on the support shaft 300 to complete the pay-off process.

[0028] The outer surface of the support plate 200 is also provided with a transverse groove 310, which has a groove structure with a certain width and depth, and the center line of the transverse groove 310 is parallel to the ground. The transverse groove 310 is located beside the support shaft 300, and preferably, the center line of the transverse groove 310 is colinear with the extension line of the radius of the support shaft 300 in the transverse direction. In addition, a compression spring 400 is also provided in the transverse groove 310, and the compression spring 400 is fixedly connected to the side wall of the transverse groove 310, and the compression spring 400 is a spiral spring.

[0029] In this embodiment, the clamping mechanism includes a baffle 500, an upper clamping plate 600 and a lower clamping plate 700, wherein the baffle 500 is slidably connected to the support plate 200 through a transverse sliding groove 310. Figure 2 As shown, a flange 510 is provided on the side of the baffle 500, and the flange 510 slides in the transverse slot 310, so that the baffle 500 can slide along the transverse slot 310 relative to the support plate 200. The portion of the baffle 500 located in the transverse slot 310 is fixedly connected to the other end of the compression spring 400.

[0030] The upper clamping plate 600 and the lower clamping plate 700 are respectively connected to the baffle plate 500 by hinge connection, that is, the upper clamping plate 600 and the lower clamping plate 700 can rotate relative to the baffle plate 500. Figure 2 As shown, the upper clamping plate 600, the lower clamping plate 700 and the baffle plate 500 are all provided with a connecting tube 520, the connecting tube 520 is provided with a connecting shaft 530, and the connecting shaft 530 is provided with a torsion spring 800, and the plate hooks at both ends of the torsion spring 800 are respectively connected to the upper clamping plate 600, the lower clamping plate 700 and the baffle plate 500. In the initial state, the upper clamping plate 600 and the lower clamping plate 700 are both in contact with the yarn wound outside the support shaft 300 under the action of the torsion spring 800. At the same time, the baffle plate 500 is in contact with the yarn wound outside the support shaft 300 under the elastic force of the compression spring 400.

[0031] In the pay-off device for a textile machine provided in the embodiment of the present application, a transverse chute 310 is provided on the side of the support shaft 300, a compression spring 400 is provided in the transverse chute 310, and the baffle 500 of the clamping mechanism is slidably arranged in the transverse chute 310 through the compression spring 400. In addition, the support shaft 300 is located in the space formed by the baffle 500, the upper clamp 600 and the lower clamp 700 in the clamping mechanism, and the baffle 500, the upper clamp 600 and the lower clamp 700 are also in contact with the yarn on the support shaft 300. In this way, when the support shaft 300 pulls the wire outward by rotating, the wire pressing mechanism can always fit the yarn, thereby effectively preventing the yarn from being messy due to looseness during the pay-off process.

[0032] In some embodiments, Figure 3 As shown, a positioning hole 910 is also provided on the support plate 200, and the positioning hole 910 is connected to the transverse slide groove 310. The positioning hole 910 is connected to the screw rod 900 by a threaded connection, so that the screw rod 900 can be screwed in and out of the positioning hole 910. A spring column 920 is fixedly provided at the end of the screw rod 900 located in the transverse slide groove 310, and the spring column 920 is fixedly connected to one end of the compression spring 400. In addition, a star-shaped handle 930 is fixed at the end of the screw rod 900 located outside the transverse slide groove 310.

[0033] With the above structural design, the screw rod 900 can be rotated according to actual conditions to adjust the elastic force of the compression spring 400. When the thickness of the yarn wound on the support shaft 300 is small, the elastic force of the compression spring 400 can be appropriately increased; otherwise, the elastic force of the compression spring 400 can be reduced, so that the clamping mechanism can always maintain the clamping state to avoid the problem of loose yarn.
