Description
TECHNICAL FIELD

[0002] If the fault of the subsequent cloth winding machine and other equipment occurs during the production process of the warp knitting machine, the cloth is not wound, the cloth is loose, the production problem causes the cloth on the knock-over plate to accumulate, and then the needle parts and the knock-over plate are extruded, the parts are damaged, the maintenance cost of replacing the needle parts and other parts is high, the maintenance time is long, and great loss is brought to the production, once the serious loop accumulation occurs, the needle parts and the knock-over plate are seriously deformed, even if the fault of the loop accumulation is excluded, the precision of the equipment is greatly affected, therefore, the cloth loosening and the tension deficiency should be found and investigated in time, for this purpose, part of the equipment in the prior art adopts the tension detector to detect the tension of the cloth, the prior art can detect the tension of the fabric, but still has some problems: the prior art does not directly detect the tension of the cloth, but detects the displacement signal of the slidable cloth guide roller after losing the tension support, and then indirectly detects the cloth surface tension, therefore, the sensitivity of the reaction is inevitably poor, and since the tension detector is arranged at the rear end of the pulling mechanism and is in the rear process of the equipment, far away from the knock-over plate and the needle parts, when the tension detector detects the insufficient tension, the position of the needle parts is often accumulated in a large area, the coil accumulation extrudes the needle parts, causes the deformation, even if the problem is found, the parts have been irreversibly damaged, high cost and long time are needed for the maintenance and replacement of the parts, and the production benefit is seriously affected, and the present case is generated. CONTENT OF THE UTILITY MODEL
[0003] The utility model solves the technical problem that a warp knitting machine cloth surface tension detection device is provided to solve the problem in the background art.
[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a warp knitting machine cloth surface tension detection device, including middle wall board, knock-over support, knock-over plate and tension detector, the knock-over support is oppositely arranged on the upper part of the middle wall board, the knock-over plate is fixedly arranged on the knock-over support, the knock-over plate forms a cloth passage for the cloth to pass through between the knock-over plates, the tension detector is arranged on the middle wall board, and the tension detector is located below the knock-over support and on one side of the cloth passage.
[0005] Preferably, the knock-over support is provided with a cloth guide mechanism below, and the tension detector is arranged between the knock-over support and the cloth guide mechanism.
[0006] Preferably, the tension detector comprises a switch and a rotatable swing arm, the swing arm is inclined to the cloth side, and the end of the swing arm is attached to the cloth surface in the cloth passage.
[0007] Preferably, the tension detector further comprises a roller arranged at the end of the swing arm, and the roller is attached to the cloth surface in the cloth passage.
[0008] Preferably, the tension detector further comprises a first support and a second support, the second support is fixed to the middle wall plate, the swing arm is rotatably arranged on the first support, and the relative position of the first support and the second support is adjustable.

Therefore, the detection sensitivity can be greatly improved, the fault response speed can be improved, and the phenomenon of loop collection can be maximally avoided, and the loss can be reduced. BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 Fig. 1 is a structural schematic view of the warp knitting machine cloth surface tension detection device of the present application.
[0013] Figure 2 Fig. 2 is a partial enlarged schematic view of Fig. 1. Figure 1 DETAILED DESCRIPTION
[0014] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application will be further described below in combination with specific embodiments.
[0015] For example, the tension detector is arranged close to the uncoiling support, the formed cloth is guided downward from the cloth passage between the uncoiling plates, and then detected by the tension detector located on one side of the cloth passage and closely attached to the cloth surface. Figure 1 As shown, the warp knitting machine cloth surface tension detection device includes a wallboard 1, a deloading support 2, a deloading plate 3 and a tension detector 4, the deloading support 2 is oppositely arranged on the upper portion of the wallboard 1, the deloading plate 3 is fixedly arranged on the deloading support 2, the deloading plate 3 on the left and right sides forms a cloth passage for the cloth 100 to pass through, the tension detector 4 is arranged on the wallboard 1, and the tension detector 4 is located below the deloading support 2 and on one side of the cloth passage. The tension detector 4 is arranged close to the deloading support 2, the formed cloth 100 is guided downward from the cloth passage between the deloading plate 3, and then detected by the tension detector 4 located on one side of the cloth passage and close to the cloth surface, and because the tension detector 4 is close to the needle and the deloading plate 3 and directly acts on the cloth to detect the tension, once the cloth surface is loose during production, the switch inside the tension detector 4 can be triggered immediately, and a signal of insufficient tension is sent, so that the detection sensitivity can be greatly improved, and the fault response speed is improved, thereby avoiding the phenomenon of loop accumulation and reducing the loss.
[0016] A cloth guiding mechanism 5 is arranged below the deloading support 2, and the tension detector 4 is arranged between the deloading support 2 and the cloth guiding mechanism 5. The tension detector 4 is arranged close to the deloading plate 3, so that the detection sensitivity can be improved.
[0017] As shown in the figure, Figure 2 The tension detector 4 includes a switch and a rotatable swing arm 41, under the tension state of the cloth surface, the swing arm 41 inclines to the cloth side, and the end of the swing arm 41 abuts against the cloth surface in the cloth passage, that is, the cloth surface supports the swing arm 41, so that the swing arm 41 maintains a certain angle, and the switch is not triggered at this angle. The switch is a contact switch, a position sensor or a rotary switch, and the like. In the working state, the end of the swing arm 41 abuts against the cloth surface in the cloth passage, when the cloth is in the tight state, the end of the swing arm 41 abuts against the cloth surface, when the cloth is normally conveyed, the swing arm 41 does not rotate, and when the cloth loses tension and becomes loose, the swing arm 41 rotates downward under the action of gravity, thereby triggering the switch, for example, triggering the rocker in the mechanical switch, and conveying the electrical signal of the loose cloth to the controller, thereby executing the operation of issuing an alarm or stopping.
[0018] The tension detector 4 further includes a roller 42 arranged at the end of the swing arm 41, and the roller 42 abuts against the cloth surface in the cloth passage. The tensioned cloth surface provides support for the roller 42, the roller 42 abuts against the cloth surface and rotates with the movement of the cloth surface, thereby reducing the damage to the cloth surface.
[0019] The tension detector 4 further comprises a first support 43 and a second support 44, the second support 44 is fixed on the middle wallboard 1, the swing arm 41 is rotatably arranged on the first support 43, and the relative positions of the first support 43 and the second support 44 are adjustable. By adjusting the relative positions of the first support 43 and the second support 44, the distance between the first support 43 and the cloth surface can be adjusted to adapt to different cloth surface thicknesses, and the sensitivity of the tension detector 4 can also be adjusted. Since the swing arm 41 needs a certain swing angle stroke to trigger the switch, when the position of the first support 43 is finely adjusted, for example, the first support 43 is away from the cloth surface by a certain distance, the swing arm 41 rotates downward by a certain swing angle, at this time, the swing angle required to trigger the switch is smaller, that is, the sensitivity of the tension detector 4 is improved, and vice versa, the sensitivity of the tension detector 4 is reduced.
[0020] The second support 44 is provided with a plurality of strip-shaped through holes 441, and the first support 43 is provided with a threaded hole 431 corresponding to each strip-shaped through hole 441. A threaded part passes through the strip-shaped through hole 441 and is connected with the threaded hole 431. The threaded part is located at the back of the second support 44 in the figure, and therefore is not shown. Loosening the threaded part can make the first support 43 move along the strip-shaped through hole 441 in the rectangular direction, so as to adjust the relative positions of the first support 43 and the second support 44. The threaded part is tightened again to fix the position of the first support 43. After the position of the first support 43 is moved, the swing angle of the swing arm 41 is changed, so as to adjust the working angle of the swing arm 41 when the cloth surface is tensioned.
[0021] The second support 44 is provided with four strip-shaped through holes 441, and the first support 43 is provided with four threaded holes 431.
[0022] The above is only a few specific embodiments of the present application, but the design concept of the present application is not limited thereto. Any non-essential modification of the present application using this concept shall be deemed as an infringement of the protection scope of the present application.
