Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic warp threading machine technology, and specifically to an automatic warp threading machine twisting protection device. Background Technology
[0002] In the textile industry, automatic warp-threading machines are essential equipment. Their function is to thread warp yarns through heddles, stop warps, and reeds according to a specific pattern, preparing them for subsequent weaving processes. During automatic warp-threading, splitting the warp yarns into upper and lower layers is a crucial step, facilitating the warp-threading operation.
[0003] Existing automatic warp threading machines are prone to warp yarn entanglement and breakage during the shunting process due to uneven warp yarn tension and insufficient precision of the shunting mechanism, which affects the quality and efficiency of warp threading. At the same time, when shunting abnormalities occur, there is a lack of effective protection mechanisms, making it difficult for operators to detect and handle problems in a timely manner, which may further damage the warp yarn and equipment. Therefore, a shunting protection device for automatic warp threading machines is proposed. Utility Model Content
[0004] This invention provides an automatic warp threading machine twisting protection device to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] An automatic warp threading machine twisting protection device, comprising:
[0007] An automatic warp threading machine slitting mechanism includes a motor, one end of the motor shaft is fixedly connected to a rotating disk, one side of the rotating disk is rotatably connected to a slitting bar, and one end of the slitting bar is connected to a pressing disk.
[0008] The twisted protection mechanism includes a mounting plate, a telescopic plate fixedly connected to the surface of the mounting plate, and a contact plate with a guide groove on its surface fixedly connected to one end of the telescopic plate.
[0009] A further improvement of the present invention is that the automatic warp threading machine's twisting mechanism also includes a support frame, and the support frame has warp rollers inside.
[0010] A further improvement of this utility model is that: a mounting rod is fixedly connected to one side of the support frame, and one side of the mounting rod is fixedly connected to one side of the motor.
[0011] A further improvement of this utility model is that: the interior of the mounting rod overlaps with the surface of the mounting plate, and the interior of another mounting rod is threaded with an adjusting screw, one end of which is rotatably connected to one side of the extrusion disc.
[0012] A further improvement of the present invention is that the twisting protection mechanism further includes a pressure sensor, the bottom of which is fixedly connected to the surface of the mounting plate, and one end of the mounting plate is provided with an insertion round head.
[0013] A further improvement of this utility model is that a spring is fixedly connected to the top of the pressure sensor, and the top of the spring is fixedly connected to the bottom of the contact plate.
[0014] A further improvement of this utility model is that a control terminal with a built-in display panel is fixedly connected to one side of the support frame surface, and an audible and visual alarm is fixedly connected to the other side of the support frame surface.
[0015] A further improvement of this utility model is that the audible and visual alarm is connected to the control terminal via a signal, and the control terminal is connected to the pressure sensor via a signal.
[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0017] This utility model provides a twisting protection device for an automatic warp threading machine. Through the twisting protection mechanism, when the twisting rod twists the warp threads, the contact plate guides the warp threads through the guide groove on the surface of the contact plate. When the warp tension is too high, exceeding the spring force, the warp threads squeeze the contact plate, causing the spring to contract and thus slightly reducing the tension. When the tension is too low, the spring slightly pushes the contact plate outward, thus increasing the tension. Simultaneously, during use, a pressure sensor detects the spring's reaction force in real time, thereby detecting the warp tension. When the tension is too high, the control terminal activates an audible and visual alarm to warn the operator, enabling them to promptly identify the problem and making the machine easier to use.

[0025] The present invention will be further described in detail below with reference to embodiments:
[0026] Example 1
[0027] like Figure 1-6 As shown, this utility model provides an automatic warping machine twisting protection device, an automatic warping machine twisting mechanism, an automatic warping machine twisting mechanism including a motor 14, one end of the motor 14 shaft is fixedly connected to a rotating disk 15, one side of the rotating disk 15 is rotatably connected to a twisting rod 18, one end of the twisting rod 18 is connected to a pressing disk 17; a twisting protection mechanism including a mounting plate 21, a telescopic plate 22 is fixedly connected to the surface of the mounting plate 21, one end of the telescopic plate 22 is fixedly connected to a contact plate 23 with a guide groove on its surface.
[0028] In this embodiment, during the twisting process, the warp yarn contacts the contact plate 23. When the warp yarn tension is too high, the contact plate 23 is squeezed, causing the spring 25 to contract, thereby slightly reducing the warp yarn tension. When the warp yarn tension is low, the spring 25 pushes the contact plate 23 outward, thereby pushing the warp yarn to move and slightly increasing the warp yarn tension. During the adjustment of the warp yarn tension, the pressure sensor 24 detects the reaction force of the spring 25 in real time, thereby indirectly detecting the warp yarn tension. The detected data is transmitted to the control terminal 27 and displayed on the display panel for the operator to observe. When the detected pressure is too high, the control terminal 27 activates the audible and visual alarm 28 to warn the operator, so that the operator can detect the fault in time and make it easier to use.
[0029] Example 2
[0030] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the automatic warp threading machine's twisting mechanism further includes a support frame 11, with a warp roller 12 disposed inside the support frame 11. A mounting rod 13 is fixedly connected to one side of the support frame 11, and one side of the mounting rod 13 is fixedly connected to one side of the motor 14. The interior of the mounting rod 13 overlaps with the surface of the mounting plate 21. An adjusting screw 16 is threadedly connected to the interior of another mounting rod 13, and one end of the adjusting screw 16 is rotatably connected to one side of the extrusion disc 17.
[0031] In this embodiment, during use, after inserting the twisting rod 18 between multiple warp threads, the angle of the twisting rod 18 is adjusted so that its axis is parallel to the axis of the rotating disk 15 and the pressing disk 17. Then, the adjusting screw 16 is rotated so that the pressing disk 17 presses and fixes the twisting rod 18.
[0032] Example 3
[0033] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the twisting protection mechanism further includes a pressure sensor 24, the bottom of the pressure sensor 24 is fixedly connected to the surface of the mounting plate 21, one end of the mounting plate 21 is provided with an insertion round head 26, the top of the pressure sensor 24 is fixedly connected to a spring 25, the top of the spring 25 is fixedly connected to the bottom of the contact plate 23, one side of the surface of the support frame 11 is fixedly connected to a control terminal 27 with a built-in display panel, the other side of the surface of the support frame 11 is fixedly connected to an audible and visual alarm 28, the audible and visual alarm 28 is signal-connected to the control terminal 27, and the control terminal 27 is signal-connected to the pressure sensor 24.
[0034] In this embodiment, by inserting the mounting plate 21 into the warp threads, multiple warp threads alternately contact the upper contact plate 23 and the lower contact plate 23. After insertion, the mounting plate 21 is fixed to the inside of the mounting rod 13 with screws. The round head 26 also prevents the mounting plate 21 from damaging the warp threads when it is inserted, making it easier to use. After insertion, the motor 14 is started to rotate the twisting rod 18 to twist the warp threads into upper and lower layers.
[0035] The working principle of the automatic warp threading machine's twisting protection device will be explained in detail below.
[0036] like Figure 1-6As shown, during use, after inserting the warp divider 18 between multiple warp threads, adjust the angle of the warp divider 18 so that its axis is parallel to the axes of the rotating disk 15 and the pressing disk 17. Then, rotate the adjusting screw 16 so that the pressing disk 17 presses and fixes the warp divider 18. After fixing, insert the mounting plate 21 into the warp threads so that multiple warp threads alternately contact the upper contact plate 23 and the lower contact plate 23. After insertion, use screws to fix the mounting plate 21 into the inside of the mounting rod 13. The design of the round head 26 also avoids damage to the warp threads when the mounting plate 21 is inserted, making it easier to use. After insertion, start the motor 14 to rotate the warp divider 18 and divide the warp threads into upper and lower layers. During the twisting process, the warp threads contact the contact plate 23. When the warp tension is too high, it squeezes the contact plate 23, causing the spring 25 to contract and thus slightly reduce the warp tension. When the warp tension is low, the spring 25 pushes the contact plate 23 outward, thereby pushing the warp threads to move and slightly increasing the warp tension. During the adjustment of the warp tension, the pressure sensor 24 detects the reaction force of the spring 25 in real time, thus indirectly detecting the warp tension. The detected data is transmitted to the control terminal 27 and displayed on the display panel for the operator to observe. When the detected pressure is too high, the control terminal 27 activates the audible and visual alarm 28 to warn the operator, so that the operator can detect the fault in time and make it easier to use.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
