Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of winding grooved drum of winding machine, specifically relates to winding grooved drum of grooved drum type winding machine. BACKGROUND

[0002] The winding machine is the special equipment of the textile industry. As the last process of spinning and the first process of weaving, the winding plays the role of the "bridge" between the two processes, and thus occupies an important position in the textile field. The grooved drum is one of the important winding components of the grooved drum type winding machine. The yarn tension and winding density during winding are the main basis for measuring the quality of the drum forming, and represent the movement law of the yarn winding and the distribution of the yarn loop on the drum. The spiral groove curve shape on the drum has a direct impact on the forming of the drum. The grooved drum is suitable for various textile machines such as chemical fiber elasticizer, drum rewinder, winding machine, doubling machine and covered yarn machine, and is a key component of chemical fiber (cotton) textile machinery related to the winding of the yarn cake and the unwinding performance. Since the depth and width of the spiral groove of the grooved drum change irregularly, it is difficult to use machining methods, and the outer surface and the groove surface are easily worn out by long-term high-speed friction with the yarn, which is one of the key loss parts in the textile machinery. Therefore, it is very important to solve the problem of easy wear of the grooved drum at home and abroad. At present, the domestic and foreign solutions to the problem of easy wear of the grooved drum are to improve the wear resistance of the grooved drum, such as equipping high-quality grooved drums, which can prolong the service life of the grooved drum, but the fundamental problem of wear has not been solved. SUMMARY

[0003] In view of the above defects or deficiencies in the prior art, it is desirable to provide a winding grooved drum of a grooved drum type winding machine.

[0004] According to the technical scheme provided by the embodiment of the present application, the winding grooved drum of the grooved drum type winding machine comprises a grooved drum body, the grooved drum body is arranged on the oppositely arranged support frames through a rotating shaft, a pressure type polishing block is slidably arranged on the support frame beside the grooved drum body through a horizontal rod B, the end portions of the pressure type polishing block are arranged in the spiral groove on the grooved drum body, the pressure type polishing block is pressed on the inner end face of the spiral groove through a compression spring, and the grooved drum body rotates through the transmission device on the support frame, so that the pressure type polishing block moves in the spiral groove.

[0005] Further, a yarn guide is slidably arranged on the support frame below the grooved drum body through a horizontal rod A, one end portion of the yarn guide is arranged in the spiral groove, and the yarn guide realizes the guidance of the yarn.

[0006] Further, the yarn guide comprises a support rod and a yarn guide ball, the yarn guide ball is located at one end portion of the support rod, and the yarn guide ball is located in the spiral groove, so as to reduce the friction between the yarn guide ball and the yarn.

[0007] Furthermore, the pressing grinding block includes a support rod, a three-pronged rod, a pressing device, and a grinding block. One end of the support rod is fixedly connected to a sliding block located on the horizontal rod B, and the other end is fixedly connected to the three-pronged rod. The grinding block is fixed to the three-pronged rod by the pressing device, which includes a telescopic rod and a compression spring. The compression spring is movably sleeved on the telescopic rod. One end of the telescopic rod is fixedly connected to the three-pronged rod, and the other end is fixedly connected to the grinding block, thereby realizing the grinding of the end face of the spiral groove.

[0008] Furthermore, there are two horizontal rods B, and the two ends of the sliding block are slidably connected to the two horizontal rods B to prevent the pressure grinding block from rotating.

[0009] Furthermore, the support rod is equipped with an inclined stabilizing rod to ensure the stability of the support rod's movement.

[0010] In summary, the beneficial effects of this application are as follows: The device of this application is equipped with a pressing and polishing device in the spiral groove of the grooved cylinder. When the yarn rubs against the inner end face of the spiral groove, the pressing and polishing device can polish the friction surface smoothly in time, preventing the yarn from moving and rubbing repeatedly, which would increase the wear in the spiral groove, reduce the wear rate of the grooved cylinder, and improve its service life.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] The winding drum of a slotted drum winding machine, such as Figure 1 and Figure 2 As shown, the horizontally placed trough body 1 is mounted on the support frame 2 via a rotating shaft, and the trough body 1 rotates relative to the support frame 2 via a transmission device fixed on the support frame 2, and a spiral groove 11 with the beginning and end connected is provided on the outer end face of the trough body 1.

[0021] A horizontal bar B3 is provided at the rear of the groove body 1. The horizontal bar B3 is horizontally fixed to the support frame 2 by a vertical bar. The horizontal bar B3 is slidably connected to the pressing grinding block 4 by a sliding block 7. The front end of the pressing grinding block 4 is set in the spiral groove 11.

[0022] A horizontal rod A5 is fixedly installed on the support frame 2 below the groove body 1. A wire guide 6 is slidably connected to the horizontal rod A5 via a slider, and the upper part of the wire guide 6 is set in the spiral groove 11.

[0023] like Figure 3 and Figure 4 As shown, the support rod 42 on the clamping grinding block 4 is supported by inclined stabilizing rods 8 provided above and below. That is, one end of the stabilizing rod 8 is fixedly connected to the sliding block 7, and the other end is fixedly connected to the support rod 42.

[0024] One end of the support rod 42 is fixedly connected to the sliding block 7 located on the horizontal rod B3, and the other end is fixedly connected to the tripod 43. The grinding block 45 is fixed to the tripod 43 by the pressing device 44.

[0025] The compression spring 41 on the pressing device 4 is movably sleeved on the telescopic rod 441. One end of the telescopic rod 441 and the compression spring 41 is fixedly connected to the trident 43, and the other end of the telescopic rod 441 and the compression spring 41 is fixedly connected to the grinding block 45. The diameter of the telescopic rod 441 is smaller than the outer diameter of the trident 43 and the grinding block 45.

[0026] like Figure 5 As shown, the wire guide ball 62 on the wire guide 6 is located on the upper end face of the support rod 61. The wire guide ball 62 is located in the spiral groove 11 and can roll on the support rod 61. The support rod 61 is fixedly connected to the slider on the horizontal rod A5.

[0027] Before use, install this device on the winding machine via the support frame 2, then pass the yarn through the guide ball 62 on the guide 6, and then start the transmission device connected to the grooved cylinder body 1 to make the grooved cylinder body 1 rotate. When the grooved cylinder body 1 rotates, since one end of the guide 6 and the pressing grinding block 4 are set in the spiral groove 11, the guide 6 and the pressing grinding block 4 can move horizontally and can move in the spiral groove 11. In this way, the guide 6 guides the yarn and prevents the yarn from being fed repeatedly, while the grinding block 45 on the pressing grinding block 4 can abut against the inner end face of the spiral groove 11 to grind the inner end face of the spiral groove 11.

[0028] Since the grinding block 45 is fixed to the three-pronged rod 43 by the pressing device 44, the grinding block 45 can correspond to the three end faces of the inner end face of the spiral groove 11 respectively. Since the pressing device 44 is composed of a telescopic rod 441 and a compression spring 41, the grinding block 45 can be pressed against the end face of the spiral groove 11 by the compression spring 41. That is, there is a certain pressure between the grinding block 45 and the inner end face of the spiral groove 11. Thus, when the grinding block 45 moves in the spiral groove 11, it has a certain friction force, which can grind the inner end face of the spiral groove 11.

[0029] Guided by the yarn guide 6, the yarn can be drawn out from the spiral groove 11. When the yarn comes into contact with the spiral groove 11 and rubs, it will cause some damage to the inner end face of the spiral groove 11. After the yarn causes slight damage to the spiral groove 11, the grinding block 45 on the pressing grinding block 4 directly grinds the spiral groove 11. In this way, it is difficult for the spiral groove 11 to be greatly damaged, which can indirectly greatly improve the service life of the groove cylinder body 1.

[0030] The three-pronged lever 43 in this design is a lever with three branches.

[0031] In this scheme, the three grinding blocks 45 correspond to the three end faces of the inner end face of the spiral groove 11. Alternatively, the outer end faces of the three grinding blocks 45 can be set to be the same as the inner end face frame of the spiral groove 11, so that the grinding blocks 45 can grind each part of the inner end face of the spiral groove 11.

[0032] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
