Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a yarn tensioning mechanism of a warp knitting machine. Background Art

[0002] A warp knitting machine primarily consists of a weaving mechanism, a guide bar traverse mechanism, a warp let-off mechanism, a take-up and take-up device, and a transmission mechanism. Adjusting the tension of a warp knitting machine is crucial for ensuring weaving quality. Adjusting the tension ensures uniform yarn tension during transport, preventing yarn tension from affecting the fabric's appearance and smoothness.

[0003] During the operation of the warp knitting machine, different yarns and different operating speeds will result in different required tension forces. However, the existing warp knitting machine tensioning mechanism can only independently adjust the tension of a single yarn, which will lead to unstable tension between the yarns and poor weaving effect. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a tensioning mechanism for a warp knitting machine, which can adjust the tensioning force according to actual conditions and keep the tension of all yarns uniform and stable.

[0005] The utility model discloses a yarn tensioning mechanism of a warp knitting machine, comprising a bracket, wherein the bracket is vertically provided with a plurality of tensioning plates, the surfaces of all the tensioning plates are parallel, and are arranged at intervals along the same axial direction of the bracket, the surfaces of the tensioning plates are provided with a plurality of guide plates, the surfaces of the guide plates are parallel to the surfaces of the tensioning plates, and the guide plates are provided with penetrating guide holes; the brackets on both sides of the tensioning plates are vertically provided with guide rods opposite to each other, the tensioning plates are slidably connected to the guide rods, a screw is vertically provided at the center of the tensioning plate, the screw is threadedly connected to the tensioning plate, and the screw is rotatably connected to the bracket; the bracket is provided with a motor, and the motor is transmission-connected to the screw.

[0006] Furthermore, the tensioning plate surface is a hollow structure, the guide plates are arranged at intervals in a rectangular shape, and the guide plates are connected to the tensioning plate in columns.

[0007] Furthermore, guide rollers are provided relatively horizontally on the guide plates on the upper and lower sides of the guide hole, the axial direction of the guide rollers is parallel to the surface of the guide plates, and a guide groove is provided in the center of the guide rollers.

[0008] The yarn tensioning mechanism of the warp knitting machine obtained by the utility model can adjust the size of the yarn tensioning force by adjusting the position of the tensioning plate, so as to achieve the same tensioning state of all yarns, thereby improving the weaving quality of the warp knitting machine.

[0011] Figure 3 This is a structural schematic diagram of the guide plate of the present utility model. DETAILED DESCRIPTION

[0012] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1-Figure 3 As shown, the utility model discloses a yarn tensioning mechanism of a warp knitting machine, including a bracket 1, wherein the bracket 1 is vertically provided with a plurality of tensioning plates 2, the surfaces of all tensioning plates 2 are parallel, and are spaced apart along the same axis direction of the bracket, the surface of the tensioning plate 2 is provided with a plurality of guide plates 3, the surface of the guide plates 3 is parallel to the surface of the tensioning plate 2, and the guide plates 3 are provided with a through guide hole 303, the guide hole 303 passes through the guide plate 3 and the tensioning plate 2, and each yarn passes through each tensioning plate 2 separately when in use. The guide holes 303 of the guide plates 3 are located in the same position. The brackets 1 on both sides of the tensioning plates 2 are vertically provided with guide rods 4. The tensioning plates 2 are slidably connected to the guide rods 4. A screw 5 is vertically provided in the middle of the tensioning plates 2. The screw 5 is threadedly connected to the tensioning plates 2 and rotatably connected to the bracket 1. Rotating the screw 5 can control the vertical displacement of the tensioning plates 2. During use, the two adjacent tensioning plates 2 are controlled to move in opposite directions, thereby increasing the tension of the yarn between the two adjacent tensioning plates 2. Each yarn passes through the guide holes 303 on the guide plates 3 on all tensioning plates 2, and the relative position of each yarn passing through the tensioning plates 2 is the same. Therefore, when there is a position difference between adjacent tensioning plates 2, the height difference of all yarns at the corresponding tensioning plates 2 is also the same, so the tension on all yarns is consistent. When adjusting the tension of the yarn, the tension on different yarns is always consistent. The bracket 1 is provided with a motor 6 , which is in transmission connection with the screw rod 5 , and each screw rod 5 is controlled by a corresponding motor 6 .

[0015] The tensioning plate 2 has a hollow structure, and the guide plate 3 is arranged in the hollow structure of the tensioning plate 2. The guide plates 3 are arranged in a rectangular pattern on the tensioning plate 2, and the rectangular pattern is an array, such as 7 rows and 4 columns. The guide plates 3 are connected to the tensioning plate 2 in columns, saving materials and reducing costs. Figure 1 As shown, the seven guide plates 3 in each row can be connected by a connector, and both ends are fixed to the tensioning plate 2 through the connector.

[0016] The guide hole 303 can be rectangular, and guide rollers 301 are horizontally provided on the guide plates 3 on the upper and lower sides of the guide hole 303. The axial direction of the guide roller 301 is parallel to the plate surface of the guide plate 3. A guide groove 302 is concavely provided in the center of the guide roller 301. When in use, the yarn is embedded in the guide groove 302, which has a limiting and guiding effect on the yarn, reducing the fluctuation of the yarn during operation to ensure stable tension.
