Technical Field

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

[0002] A warp knitting machine is a machine used to weave fabrics. It forms a knitted fabric by simultaneously looping one or more parallel yarns on all needles fed into the machine in the warp direction. The yarn tensioning mechanism of a warp knitting machine is a crucial component for ensuring the yarn maintains proper tension during the knitting process.

[0003] Existing yarn tensioning structures often lack early warning functions. When a thread breakage problem occurs during the weaving process, it is easy to fail to detect and handle it in time, which can easily lead to production interruptions and reduce production efficiency.

[0022] 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 the embodiments.

[0023] Reference Figure 1-5 A tensioning structure for a warp knitting machine includes a fixed base 1, on the top of which a first fixed roller assembly 2-1, a tensioning assembly, and a second fixed roller assembly 2-2 are equidistantly arranged in sequence, and an alarm body 6 is arranged on one side of the top of the fixed base 1. The tensioning assembly includes two mounting seats 3, between which a tensioning roller assembly 4 is slidably arranged, and an adjustment assembly 5 is screwed above the tensioning roller assembly 4 in the mounting seats 3;

[0024] In addition, the tensioning roller assembly 4 includes two fixed sliders 41, and a first fixed shaft 42 is fixedly installed between the two fixed sliders 41. The outer wall of the first fixed shaft 42 is fixedly sleeved with a tensioning roller body 43, and the outer wall of the tensioning roller body 43 is provided with multiple wire grooves 431 at equal distances, and the bottom of the tensioning roller body 43 is located in the wire grooves 431 and is slidably provided with auxiliary guide components.

[0025] Meanwhile, the auxiliary guide assembly includes two limiting sliders 4321 , a second fixed shaft 4323 is fixedly installed between the two limiting sliders 4321 , and an auxiliary roller 4322 is sleeved on the outer wall of the second fixed shaft 4323 at the guide groove 431 .

[0026] At the same time, the two limiting sliders 4321 are slidably set in the tensioning roller body 43, and movable cavities are opened in the tensioning roller body 43 at the limiting slider 4321 and the second fixed shaft 4323, and an auxiliary cavity is opened in the tensioning roller body 43 at the auxiliary roller 4322.

[0027] At the same time, a button 4325 is provided at the bottom of the movable cavity, directly below the limit slider 4321. The button 4325 controls the alarm body 6 through an electrical signal connection. A spring 4324 is provided in the movable cavity, above the limit slider 4321. One side of the spring 4324 is connected to the limit slider 4321, and the other end of the spring 4324 is connected to the top of the movable cavity.

[0028] The adjustment assembly 5 includes a limiting ring 53, a fixing screw 51 is installed in the middle of the top of the limiting ring 53, one end of the fixing screw 51 passes through the mounting seat 3 and is fixedly connected to the handle portion 52, and a placement cavity is opened in the fixed slider 41 at the limiting ring 53, and a clamping through hole is opened in the fixed slider 41 at the fixing screw 51, and the diameter of the clamping through hole is larger than the diameter of the fixing screw 51.

[0029] In addition, the fixed slider 41 is set in the mounting seat 3 for limited sliding, and the mounting seat 3 has limited sliding grooves at the fixed slider 41 and the first fixed shaft 42, and a threaded through hole is opened at the fixing screw 51 in the mounting seat 3.

[0030] In addition, the first fixed roller assembly 2-1 and the second fixed roller assembly 2-2 each include two limiting seats, a third fixed shaft is fixedly installed between the two limiting seats, and a fixed roller is sleeved on the outer wall of the third fixed shaft.

[0031] It is also worth noting that the height of the fixed roller of the first fixed roller assembly 2-1 from the fixed base 1 is consistent with the height of the fixed roller of the second fixed roller assembly 2-2 from the fixed base 1, and the height of the tensioning roller body from the fixed base 1 is always less than the height of the fixed roller of the first fixed roller assembly 2-1 from the fixed base 1.

[0032] Furthermore, it is worth noting that the specific structure and working mode of the alarm body 6 are existing technologies currently disclosed on the market, and do not belong to the main technical problems to be solved in this technical solution, so they are not described in detail in this utility model.

[0033] In this embodiment, the yarn is passed through the bottom of the auxiliary wire groove of the fixed roller of the first fixed roller assembly 2-1, the bottom wire groove of the tensioning roller body and the top of the auxiliary wire groove of the fixed roller of the second fixed roller assembly 2-2, wherein the first fixed roller assembly 2-1, the second fixed roller assembly 2-2 and the tensioning roller assembly 4, the adjustment assembly 5 are arranged in coordination, so that the yarn can be tensioned. At the same time, through the coordinated arrangement of the auxiliary guide assembly, the button 4325 and the alarm body 6, when the yarn breaks, the alarm can quickly sound an alarm, so that the staff can immediately discover and deal with the break problem, avoid production interruption caused by breakage, and thus ensure its production efficiency.

[0034] The fixed screw 51 is rotated by holding the handle 52 to drive the fixed slider 41 to move up and down, thereby adjusting the height of the tensioning roller body 43, thereby tensioning the yarn and adjusting the yarn tension.

[0035] Moreover, when the yarn passes through the bottom wire groove of the tensioning roller body, the yarn is located below the auxiliary roller 4322, and the yarn drives the auxiliary roller 4322 to move upward, away from its button 4325. When the yarn breaks, the limiting slider 4321 moves to the bottom of the movable cavity under the action of its own weight and presses its button 4325. The button 4325 is controlled to open the alarm body 6 through an electrical signal connection. The alarm can quickly sound an alarm, so that the staff can immediately discover and deal with the break problem, avoid production interruption caused by breakage, and thus ensure their production efficiency.

[0036] Furthermore, the spring 4324 acts as a buffer when the limiting slider 4321 presses the button 4325 under the action of its own weight, thereby avoiding damage to the button 4325 .

[0037] In the utility model, the coordinated arrangement of the first fixed roller assembly (2-1), the second fixed roller assembly (2-2), the tensioning roller assembly 4, and the adjusting assembly 5 facilitates the tensioning of the yarn. At the same time, through the coordinated arrangement of the auxiliary guide assembly, the button 4325, and the alarm body 6, when the yarn breaks, the alarm can quickly sound an alarm, allowing the staff to immediately discover and deal with the breakage problem, avoiding production interruption caused by the breakage, thereby ensuring their production efficiency.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
