Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, specifically to a yarn storage tube insertion mechanism and its twisting machine. Background Technology

[0002] When operating a doubling machine, the yarn storage bobbin must be installed first, and then removed after the yarn winding is complete. Currently, while the insertion mechanism of the equipment meets basic installation requirements, its fixed-size design (height and diameter) only accommodates yarn storage bobbins of specific specifications. When encountering yarn storage bobbins with different inner diameters or heights, matching insertion parts must be replaced. This rigid design not only limits the equipment's applicability but also leads to frequent parts replacements, impacting production efficiency and increasing equipment operating costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plug-in mechanism for yarn storage tubes and its double twisting machine, so as to solve the technical problem that the double twisting machine needs to replace the matching plug-in component when changing yarn storage tubes of different specifications.

[0004] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a plug-in mechanism for a yarn storage tube, comprising:

[0005] Mounting base;

[0006] A positioning cylinder, which is rotatably connected to a mounting base;

[0007] An adjusting cylinder, one end of which is slidably sleeved outside the positioning cylinder;

[0008] A tensioning and fixing structure is provided on both the positioning cylinder and the adjusting cylinder, and each tensioning and fixing structure includes multiple tensioning claws arranged inside and outside the positioning cylinder or adjusting cylinder in the circumferential direction.

[0009] A gripper adjustment assembly is disposed inside the positioning cylinder and passes through the adjustment cylinder, and is connected to each tensioning gripper to control multiple tensioning grippers to slide synchronously in and out of the positioning cylinder or adjustment cylinder.

[0010] A height adjustment component is connected between a tensioning jaw that engages on the positioning cylinder and a tensioning jaw that engages on the adjusting cylinder to adjust the distance between them.

[0011] Technical principle:

[0012] The distance between the tensioning jaws on the positioning cylinder and the adjusting cylinder is adjusted by the height adjustment component. During this adjustment process, the adjusting cylinder slides relative to the positioning cylinder, so that the multiple tensioning jaws in the two tensioning fixing structures can be used to tension and fix yarn storage cylinders of different heights. The size of the circle where the clamping end of the multiple tensioning jaws in each tensioning fixing structure is located is adjusted by adjusting the multiple tensioning jaws in the two tensioning fixing structures to slide inward and outward of the positioning cylinder or the adjusting cylinder, thus satisfying the tensioning and fixing of yarn storage cylinders of different diameters.

[0013] The second aspect of this utility model adopts the following technical solution: a twisting machine, including a yarn storage tube insertion mechanism as described in the first aspect of this utility model.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The insertion mechanism for this yarn storage tube mainly consists of a mounting base, a positioning cylinder, an adjusting cylinder, a tensioning and fixing structure composed of multiple tensioning claws, a claw adjusting component, and a height adjusting component. It can meet the requirements of tensioning and fixing yarn storage tubes of different heights and diameters. Therefore, when changing yarn storage tubes of different heights and diameters, there is no need to change the insertion mechanism, which is beneficial to improving the working efficiency of the twisting machine and reducing equipment costs.

Detailed Implementation

[0021] The present invention will be further described in detail below through specific embodiments:

[0022] like Figures 1-4As shown in the figure, this utility model embodiment proposes a plug-in mechanism for a yarn storage tube, including a mounting base 1, a positioning tube 2, an adjusting tube 3, a tensioning and fixing structure 4, a gripper adjusting assembly 5, and a height adjusting assembly 6. The positioning tube 2 is rotatably connected to the mounting base 1; one end of the adjusting tube 3 is slidably sleeved outside the positioning tube 2; the tensioning and fixing structure 4 is provided on both the positioning tube 2 and the adjusting tube 3, and each tensioning and fixing structure 4 includes multiple tensioning grippers 41 arranged inside and outside the positioning tube 2 or the adjusting tube 3 along its circumferential direction; the gripper adjusting assembly 5 is disposed inside the positioning tube 2 and passes through the adjusting tube 3, and is connected to each tensioning gripper 41 to control the multiple tensioning grippers 41 to slide synchronously inside and outside the positioning tube 2 or the adjusting tube 3; the height adjusting assembly 6 is connected between the tensioning grippers 41 on the positioning tube 2 and the tensioning grippers 41 on the adjusting tube 3 to adjust the distance between them.

[0023] When replacing the yarn storage tube:

[0024] The distance between the tensioning claws 41 on the positioning cylinder 2 and the tensioning claws 41 on the adjusting cylinder 3 is adjusted by the height adjustment component 6. During this adjustment process, the adjusting cylinder 3 slides relative to the positioning cylinder 2, so that the multiple tensioning claws 41 in the two tensioning fixing structures 4 can be used to tension and fix yarn storage cylinders of different heights. The size of the circle where the clamping end of the multiple tensioning claws 41 in each tensioning fixing structure 4 is located is adjusted by adjusting the multiple tensioning claws 41 in the two tensioning fixing structures 4 to slide inward and outward in the positioning cylinder 2 or the adjusting cylinder 3, so as to meet the requirements of tensioning and fixing yarn storage cylinders of different diameters.

[0025] The insertion mechanism for this yarn storage tube mainly consists of a mounting base 1, a positioning cylinder 2, an adjusting cylinder 3, a tensioning and fixing structure 4 composed of multiple tensioning claws 41, a claw adjusting assembly 5, and a height adjusting assembly 6. It can meet the requirements of tensioning and fixing yarn storage tubes of different heights and diameters. Therefore, when changing yarn storage tubes of different heights and diameters, there is no need to change the insertion mechanism, which is beneficial to improving the working efficiency of the twisting machine and reducing equipment costs.

[0026] In this embodiment, the number of tensioning claws 41 in the two tensioning fixing structures 4 is shown as two, but the specific number can be adjusted reasonably according to actual needs.

[0027] To better understand this solution, the following section will describe the structures such as the gripper adjustment component 5 and the height adjustment component 6 in detail.

[0028] First is the gripper adjustment component 5.

[0029] like Figures 1-4As shown, according to another embodiment of the present invention, the insert mechanism for the yarn storage tube includes a gripper adjustment assembly 5 comprising a driver 51 and an adjustment part. The driver 51 is disposed inside the positioning cylinder 2 and is connected to an adjustment screw 52 extending axially from the positioning cylinder 2 into the adjustment cylinder 3. There are two adjustment parts, both of which are threadedly connected to the adjustment screw 52. The two adjustment parts respectively cooperate with a plurality of tensioning grippers 41 on the positioning cylinder 2 and the adjustment cylinder 3.

[0030] In this embodiment, the driver 51 provides power to drive the adjusting screw 52 to rotate. During the rotation, the adjusting screw 52 drives the two adjusting parts to move towards or away from each other, so as to drive the multiple tensioning claws 41 in the two tensioning fixing structures 4 to move synchronously in the positioning cylinder 2 or the adjusting cylinder 3 in the direction of inside or outside, so as to satisfy the tensioning and fixing of yarn storage cylinders of different diameters.

[0031] The driver 51 can be a stepper motor.

[0032] Based on the above solution:

[0033] Each of the adjustment parts includes an adjustment frustum 53, which is threadedly connected to the adjustment screw 52. Each tensioning claw 41 has a guide groove 54 arranged along the length of its outer wall on one end. One end of the tensioning claw 41 is slidably embedded in the guide groove 54 and forms an adjustment slope that slides against the inner wall of the guide groove 54.

[0034] In this embodiment, the large ends of the adjusting frustums 53 in the two adjusting parts are arranged facing each other. The guide groove 54 cooperates with the adjusting inclined surface of the corresponding tensioning claw 41 to drive the tensioning claw 41 to move. On the other hand, when the driver 51 drives the adjusting screw 52 to rotate, it limits and guides the adjusting frustum 53 so that the adjusting frustum 53 moves linearly along the axial direction of the adjusting screw 52.

[0035] Furthermore, each of the tensioning claws 41 is connected to an elastic telescopic member 55 between its outer end on the positioning cylinder 2 or adjusting cylinder 3 and the outer wall of the positioning cylinder 2 or adjusting cylinder 3. Here, the elastic telescopic member 55 can be an existing elastic telescopic rod or spring, which cooperates with the tensioning claw 41 so that during the movement of the tensioning claw 41, the tensioning claw 41 and the corresponding adjusting platform 53 always maintain a sliding abutment state, which is beneficial for the tensioning claw 41 to be stably placed inside the yarn storage cylinder for tensioning and fixing.

[0036] Secondly, there is the tensioning clamp 41.

[0037] like Figure 1 and Figure 2As shown, according to another embodiment of the present invention, the yarn storage tube insertion mechanism wherein the tensioning claw 41 is T-shaped, the adjusting inclined surface is opened on the end of the vertical section of the tensioning claw 41, the horizontal section of the tensioning claw 41 is placed outside the positioning cylinder 2 or the adjusting cylinder 3, and both ends of the horizontal section of the tensioning claw 41 are connected to the outer wall of the positioning cylinder 2 or the adjusting cylinder 3 with elastic telescopic members 55, so as to make the tensioning claw 41 more stable during movement.

[0038] Next is the height adjustment component 6.

[0039] like Figures 1-4 As shown, according to another embodiment of the present invention, the yarn storage tube insertion mechanism includes a height adjustment component 6 comprising an electric telescopic rod 61 connected between two corresponding tensioning jaws 41.

[0040] In this embodiment, the electric telescopic rod 61 is telescopically adjusted to control the movement of the corresponding two tensioning claws 41 toward or away from each other. At the same time, the adjusting cylinder 3 moves toward or away from the positioning cylinder 2 to meet the need for tensioning and fixing of yarn storage cylinders at different heights.

[0041] In this embodiment, since the number of tensioning claws 41 in both tensioning and fixing structures 4 is shown as two, in order to improve the stability of the distance adjustment between the two tensioning and fixing structures 4, one of the tensioning claws 41 in the two tensioning and fixing structures 4 is connected by an electric telescopic rod 61, and the other tensioning claw 41 in the two tensioning and fixing structures 4 can be connected by an electric telescopic rod 61 or an elastic telescopic rod, so as to ensure the stability of the two tensioning and fixing structures 4 in the distance adjustment process by using two electric telescopic rods 61 in cooperation or one electric telescopic rod 61 in cooperation with one elastic telescopic rod.

[0042] Finally, there are the remaining structures.

[0043] like Figure 1 and Figure 3 As shown, according to another embodiment of the present utility model, the plug-in mechanism for the yarn storage tube is provided, wherein the top of the mounting base 1 has a mounting groove 11, a power unit 7 is provided in the mounting groove 11, the power unit 7 is connected to a positioning disk 8 rotatably disposed on the top surface of the mounting base 1, and the positioning disk 8 is fixedly sleeved on the outer side of the bottom end of the positioning tube 2.

[0044] In this embodiment, when the mounting base 1 is installed at the corresponding position on the twisting machine, after the insertion mechanism tightens and fixes the yarn storage cylinder, the bottom end of the yarn storage cylinder abuts against the positioning plate 8; then the starter 7 can drive the yarn storage cylinder to work.

[0045] The power unit 7 can be an electric motor.

[0046] To dissipate heat from the power unit 7, the side wall of the mounting base 1 has heat dissipation holes 9 that communicate with the mounting groove 11; the heat generated by the power unit 7 is released through the heat dissipation holes 9. There may be two heat dissipation holes 9 arranged facing each other, which facilitates air convection and accelerates the release of heat generated by the power unit 7.

[0047] As described above, both the motor and the electric telescopic rod 61 can be controlled by switches to start and stop them for convenient operation.

[0048] When using:

[0049] Activate the electric telescopic rod 61 to adjust the distance between the two tensioning and fixing structures 4 to the required level according to the height of the yarn storage cylinder;

[0050] Start the driver 51, and drive the tensioning jaws 41 to move in and out of the positioning cylinder 2 or adjusting cylinder 3 as needed, according to the diameter of the yarn storage cylinder.

[0051] According to another embodiment of the present invention, the double twisting machine includes a yarn storage tube insertion mechanism as described in any of the above embodiments, as well as other existing structures, and has the above-mentioned structural advantages.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
