Description

Technical Field

[0001] The utility model relates to the technical field of filtering, in particular to a tensioning mechanism for winding yarns. Background Art

[0002] In the process of yarn weaving, it is usually necessary to reel the yarn in for storage. However, during the reeling process, if the yarn becomes loose, the reeled yarn will become loose, affecting the reeling effect. Therefore, in the previous step of the reeling device, a tensioning mechanism is usually prepared to tension the yarn.

[0003] However, the existing tensioning structure is relatively simple. Usually, two vertical poles are placed on both sides of the rotating roller, and then a spring is arranged on the vertical pole. The height of the roller is raised by the spring to complete the tensioning of the yarn, but the tensioning force cannot be adjusted. Therefore, when yarns of different materials are tensioned, the yarns of poorer materials are prone to break. For this reason, we propose a yarn winding tensioning mechanism to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art involved in the background technology and proposes a tensioning mechanism for yarn winding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The elastic support of the support spring can be adjusted by adjusting the position of the connecting plate, thereby changing the elastic force of the support top rod, thereby completing the adjustment of the tensioning force to adapt to the use of yarns of different materials.

[0008] Preferably, the ends of the connecting rods are all provided with fixing blocks, one end of the supporting spring is fixedly connected to the fixing block, and the other end of the supporting spring is fixedly connected to the connecting plate;

[0009] The fixed block can support the support spring, so that the support spring can better support the support top rod and avoid the support spring from sliding.

[0010] Preferably, a sliding block is sleeved on the outside of the supporting top rod, and the cross-sectional shape of the sliding block is an I-shape;

[0011] The yarn can be placed inside the sliding block for tensioning, so that the yarn will not deviate during the tensioning process, and the yarn will be more stable during the winding process.

[0012] Preferably, the sliding block is sleeved with a rotating block on its exterior, a mounting block is disposed on the side of the sliding block, and a threaded rod is inserted at the end of the mounting block;

[0013] The rotating block can be rotated outside the sliding block, thereby reducing the friction between the yarns, thereby preventing the yarns from being broken due to excessive wear.

[0014] Preferably, grooves are arranged around the top end of the threaded rod, and an extrusion limit block is arranged at the bottom end of the threaded rod;

[0015] After the sliding block is adjusted left and right, the movement can be completed by rotating the threaded rod, and then the extrusion limit block and the outer wall of the connecting rod are squeezed to fix the position of the sliding block, thereby achieving a better limiting effect of the yarn.

[0016] Preferably, a transmission rod is inserted at the center of the bottom end of the support seat, and the top end of the transmission rod is movably connected to the middle position of the connecting plate;

[0017] The connecting plate can be moved by rotating the transmission rod, and the connecting plate is supported by the threaded self-locking mechanism of the transmission rod, so that the connecting plate can be fixed after being supported.

[0018] Preferably, a rotating disk is provided at the bottom end of the transmission rod, and slots are provided around the outer wall of the rotating disk;

[0019] It can make it more convenient for personnel to turn, thereby making it more convenient to complete the support of the support spring after the connecting plate moves.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model can allow the yarn to pass through the bottom of two sets of connecting rollers, and at the same time, the yarn is located above the sliding block. At this time, the sliding block can be raised by the supporting spring to complete the tensioning of the yarn. At the same time, the connecting plate can be driven to move by rotating the transmission rod, so that the connecting plate squeezes the supporting spring and adjusts the pressure coefficient of the supporting spring, thereby completing the adjustment of the tensioning force of the yarn to adapt to yarns of different materials.

[0022] 2. The utility model can slide the sliding block to change the position of the sliding block, and the yarn is placed on the sliding block, which can reduce the range of movement of the yarn, thereby avoiding the situation where the yarn swings sharply, thereby making the yarn winding effect better, and after the sliding block slides, it can be squeezed and fixed by the threaded rod and the extrusion limit block, thereby completing the positioning of the yarn.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-4The tensioning mechanism for winding a yarn is shown, and support legs 2 are provided at the four ends of a support seat 1, and connecting rollers 3 are provided at the tops of every two groups of support legs 2, and then connecting rods 4 are inserted at both ends at the middle position of the support seat 1, and a supporting top rod 5 is provided at the top of the connecting rod 4, and at the same time, a supporting spring 12 is sleeved on the outside of the connecting rod 4, so that a connecting plate 13 is provided above the support seat 1, and both ends of the connecting plate 13 are sleeved on the outside of the two groups of connecting rods 4, and then the connecting plate 13 is located below the supporting spring 12, and at the same time, a fixing block 11 is provided at the end of the connecting rod 4, so that one end of the supporting spring 12 is fixedly connected to the fixing block 11, and the other end of the supporting spring 12 is fixedly connected to the connecting plate 13, and then at the bottom end of the support seat 1 A transmission rod 14 is inserted at the center position, and the top end of the transmission rod 14 is movably connected to the middle position of the connecting plate 13, so that a rotating disk 15 is provided at the bottom end of the transmission rod 14, and slots are opened around the outer wall of the rotating disk 15. The transmission rod 14 can be driven to move by rotating the rotating disk 15, and the transmission rod 14 drives the connecting plate 13 to move, so that the connecting plate 13 squeezes the support spring 12. When the position of the connecting plate 13 changes, the bottom end of the support spring 12 can be driven to change, so that the position of the support top rod 5 can be driven to change through the elasticity of the support spring 12 itself. Therefore, the support strength of the support spring 12 can be changed by changing the line spacing of the support spring 12, so that the support spring 12 can adjust the tension coefficient of the support top rod 5.

[0030] For a detailed description of the sliding block 6 in this embodiment, please refer to Figure 2 and Figure 3 A sliding block 6 is sleeved on the outside of the supporting top rod 5, and the cross-sectional shape of the sliding block 6 is an I-shape. At the same time, a rotating block 7 is sleeved on the outside of the sliding block 6, so that a mounting block 8 is provided on the side of the sliding block 6, and a threaded rod 9 is inserted at the end of the mounting block 8, and then grooves are provided around the top end of the threaded rod 9, and an extrusion limit block 10 is provided at the bottom end of the threaded rod 9.

[0031] Working principle: When the device is in use, the yarn is passed under the two sets of connecting rollers 3, and the yarn is located above the sliding block 6 for connection. Then, the elastic coefficient of the support spring 12 can be adjusted according to the material of the yarn. The connecting plate 13 can be driven to move by rotating the transmission rod 14, and the connecting plate 13 drives the support spring 12 to move, so that the support force of the support spring 12 on the support top rod 5 changes, so that the support top rod 5 drives the sliding block 6 to change the tensioning force of the yarn, thereby avoiding the yarn breakage.

[0032] The sliding block 6 can be slid to change the supporting position of the yarn, thereby avoiding the yarn from being offset, and further reducing the friction coefficient of the yarn. At the same time, the threaded rod 9 can be rotated to drive the extrusion limit block 10 to squeeze the outer wall of the connecting rod 4, thereby limiting the sliding block 6, thereby making the sliding block 6 more stable.

[0033] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
