Description

Technical Field

[0001] The utility model relates to the technical field of warping machines, in particular to a yarn-breaking automatic stop structure used on a warping machine. Background Art

[0002] The warping machine is a warping device used to wind the yarns on multiple bobbins onto the warp beam. In the process of transmitting the yarns from the bobbins to the warp beams, the yarns may break, so a yarn breakage automatic stop device needs to be set on the warping machine, that is, when the yarn breaks, the warping machine can automatically stop running, so that the staff can easily find the broken yarn and connect it. The yarn breakage automatic stop device on the market generally includes a warp stop plate and a bracket arranged under the warp stop plate. The working process is as follows: during the transmission process, the yarn will pass through the through hole opened on the warp stop plate, and the warp stop plate will be supported so that it is suspended on the bracket. When the yarn breaks, the warp stop plate will fall, and at the same time as the warp stop plate falls, the warp stop plate will trigger the switch arranged on the bracket to control the warping machine to stop.

[0003] A Chinese utility model patent with publication number CN204939734U discloses a yarn breakage self-stop mechanism for a warping machine, the technical key points of which are that it comprises a bracket and a warp stop plate, the warp stop plate is movably arranged along the height direction of the bracket, an open slot is provided on the top of the warp stop plate, a support shaft is arranged in the open slot, and a yarn guide wheel is rotatably arranged on the support shaft. The utility model provides a yarn breakage self-stop mechanism for a warping machine that can reduce the friction between the yarn and the warp stop plate.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device keeps the warp stop plate stable by connecting the yarn and the yarn guide groove. When the yarn breaks, the warp stop plate automatically falls under the action of gravity, thereby triggering the control switch. However, in actual use, when the warp stop plate is driven only by gravity, it may get stuck in the middle, and the control switch cannot be accurately triggered, resulting in a poor user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a yarn breakage automatic stop structure for a warping machine.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a yarn breakage automatic stop structure for a warping machine, comprising a bracket, a slide groove is provided on the inner wall of the bracket, a control switch for controlling the warping machine is provided on the inner bottom wall of the slide groove, a warp stop plate is slidably provided in the slide groove, a yarn guide wheel is rotatably provided on the upper end of the warp stop plate, a fixed groove is provided on the inner bottom wall of the slide groove, an elastic rope is fixed on the inner bottom wall of the fixed groove, and the other end of the elastic rope is fixed to the bottom surface of the warp stop plate.

[0007] By adopting the above technical solution, when the staff needs to use the warping machine, the staff needs to connect the yarn in the process of being transferred from the yarn tube to the warp beam with the bottom surface of the yarn guide wheel, so that the yarn can support the warp stop plate. Subsequently, when the yarn breaks, the warp stop plate moves downward under the combined action of the elastic rope and gravity, so that the bottom of the warp stop plate contacts the control switch, and then the warping machine stops running, thereby reducing the difficulty of operation for the staff and improving the stability of the device.

[0008] Furthermore, a movable groove is provided on the inner bottom wall of the slide groove, a movable plate is slidably arranged in the movable groove, and the upper surface of the movable plate is fixed to the bottom surface of the warp stop sheet.

[0009] By adopting the above technical solution, when the yarn supports the warp stop piece, the movable plate closes the chute, thereby reducing the probability of impurities such as ash entering the chute, thereby reducing the probability of damage to the warp stop piece, thereby improving the user experience of the staff.

[0010] Furthermore, an electromagnet is arranged on the inner bottom wall of the bracket, a magnet block is arranged on the bottom surface of the warp stop plate, and a control component for controlling whether the electromagnet is energized is arranged on the warp stop plate.

[0011] Furthermore, the control component includes a battery arranged on a bracket, a rotating rod rotatably arranged on the upper end of the warp stop plate, a first metal sheet fixed on the side wall of the rotating rod, a second metal sheet fixed on the upper end of the warp stop plate, and a connecting ring arranged at the end of the rotating rod, and the electromagnet, the battery, the first metal sheet and the second metal sheet are connected in series with each other.

[0012] By adopting the above technical solution, when the yarn supports the warp stop sheet, the worker only needs to make the yarn pass through the connecting ring, so that the rotating rod can remain suspended under the action of the yarn. At this time, the first metal sheet and the second metal sheet abut each other, so that the electromagnet remains energized, so that the electromagnet repels the magnet block, thereby reducing the probability of the yarn breaking under the action of the elastic rope. Subsequently, when the yarn breaks naturally, the rotating rod rotates downward, so that the first metal sheet moves with the rotating rod and separates from the second metal sheet, so that the electromagnet is de-energized, and the warp stop sheet moves downward under the action of the elastic rope.

[0013] Furthermore, a silicone pad is provided on the bottom surface of the warp stop sheet.

[0014] Furthermore, the thickness of the silicone pad is greater than the height of the electromagnet.

[0015] By adopting the above technical solution, when the warp stop sheet moves downward under the action of the elastic rope, the silicone pad supports the warp stop sheet, thereby reducing the probability of the warp stop sheet directly hitting the electromagnet, thereby reducing the probability of the electromagnet being damaged.

[0016] Furthermore, a receiving groove for receiving a connecting ring is provided at the upper end of the warp stop sheet.

[0017] By adopting the above technical solution, the probability of the connecting ring directly hitting the warp stop sheet is reduced, thereby reducing the probability of the warp stop sheet being damaged.

[0018] Furthermore, the elastic rope is an elastic rope made of rubber band.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, when the staff needs to use the warping machine, the staff needs to connect the yarn in the process of being transferred from the yarn tube to the warp beam with the bottom surface of the yarn guide wheel, so that the yarn can support the warp stop plate. Then, when the yarn breaks, the warp stop plate moves downward under the combined action of the elastic rope and gravity, so that the bottom of the warp stop plate contacts the control switch, and then the warping machine stops running, thereby reducing the difficulty of operation for the staff and improving the stability of the device;

[0021] 2. In this application, when the yarn supports the warp stop piece, the movable plate closes the chute, thereby reducing the probability of impurities such as ash entering the chute, thereby reducing the probability of damage to the warp stop piece, thereby improving the user experience of the staff;

[0022] 3. In the present application, when the yarn supports the warp stop sheet, the worker needs to make the yarn pass through the connecting ring so that the rotating rod can remain suspended under the action of the yarn. At this time, the first metal sheet and the second metal sheet abut against each other, so that the electromagnet remains energized, so that the electromagnet repels the magnet block, thereby reducing the probability of the yarn breaking under the action of the elastic rope. Subsequently, when the yarn breaks naturally, the rotating rod rotates downward, so that the first metal sheet moves with the rotating rod and separates from the second metal sheet, so that the electromagnet is de-energized, and the warp stop sheet moves downward under the action of the elastic rope.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] like Figure 1-4 As shown, the embodiment of the present application discloses a yarn breakage automatic stop structure for a warping machine, comprising a bracket 1, a control switch 2, a warp stop piece 21, a yarn guide wheel 3, an elastic rope 4, a movable plate 5, an electromagnet 51, a magnet block 6, a control component 7 and a silicone pad 8. A slide groove 11 is provided on the inner wall of the bracket 1, and the control switch 2 is arranged on the inner bottom wall of the slide groove 11 for controlling the warping machine. The warp stop piece 21 is slidably arranged in the slide groove 11, and the yarn guide wheel 3 is rotatably arranged at the upper end of the warp stop piece 21. A fixed groove 31 is provided on the inner bottom wall of the slide groove 11, one end of the elastic rope 4 is fixed on the inner bottom wall of the fixed groove 31, and the other end of the elastic rope 4 is fixed on the bottom surface of the warp stop piece 21, and the elastic rope 4 is made of rubber band.

[0030] A moving groove 41 is provided on the inner bottom wall of the chute 11, and the moving plate 5 is a plate-shaped structure. The moving plate 5 is slidably arranged in the moving groove 41, and the upper surface of the moving plate 5 is fixed to the bottom surface of the warp stop sheet 21. When the yarn supports the warp stop sheet 21, the moving plate 5 closes the chute 11, thereby reducing the probability of impurities such as ash entering the chute 11, thereby reducing the probability of damage to the warp stop sheet 21, thereby improving the use experience of the staff.

[0031] The electromagnet 51 is arranged on the inner bottom wall of the bracket 1 . The magnet block 6 is a block-shaped structure. The magnet block 6 is arranged on the bottom surface of the warp stop plate 21 .

[0032] The control assembly 7 is arranged on the warp stop plate 21, and is used to control whether the electromagnet 51 is energized or not. The control assembly 7 includes a battery 71, a rotating rod 72, a first metal sheet 73, a second metal sheet 74, and a connecting ring 75. The battery 71 is arranged on the bracket 1, and the rotating rod 72 is a rod-shaped structure, and the rotating rod 72 is rotatably arranged on the upper end of the warp stop plate 21. The first metal sheet 73 is a sheet-shaped structure, and the first metal sheet 73 is fixed on the side wall of the rotating rod 72. The second metal sheet 74 is a sheet-shaped structure, and the second metal sheet 74 is fixed on the upper end of the warp stop plate 21, and the electromagnet 51, the battery 71, the first metal sheet 73, and the second metal sheet 74 are connected in series. The connecting ring 75 is a circular ring-shaped structure, and the connecting ring 75 is arranged at the end of the rotating rod 72.

[0033] When the yarn supports the warp stop sheet 21, the worker needs to make the yarn pass through the connecting ring 75, so that the rotating rod 72 can remain suspended under the action of the yarn. At this time, the first metal sheet 73 and the second metal sheet 74 abut against each other, so that the electromagnet 51 remains energized, so that the electromagnet 51 repels the magnet block 6, thereby reducing the probability of the yarn breaking under the action of the elastic cord 4. Subsequently, when the yarn breaks naturally, the rotating rod 72 rotates downward, so that the first metal sheet 73 moves with the rotating rod 72 and separates from the second metal sheet 74, so that the electromagnet 51 is de-energized, and the warp stop sheet 21 moves downward under the action of the elastic cord 4.

[0034] In order to reduce the probability of damage to the electromagnet 51, a silicone pad 8 is provided on the bottom surface of the warp stop sheet 21, and the thickness of the silicone pad 8 is greater than the height of the electromagnet 51. When the warp stop sheet 21 moves downward under the action of the elastic rope 4, the silicone pad 8 supports the warp stop sheet 21, thereby reducing the probability of the warp stop sheet 21 directly hitting the electromagnet 51, thereby reducing the probability of damage to the electromagnet 51.

[0035] In order to reduce the probability of the connecting ring 75 directly hitting the warp stop plate 21 , thereby reducing the probability of the warp stop plate 21 being damaged, an accommodating groove 9 for accommodating the connecting ring 75 is opened at the upper end of the warp stop plate 21 .

[0036] The working principle of the yarn breakage automatic stop structure for the warping machine in this embodiment is as follows: when the staff needs to use the warping machine, the staff needs to connect the yarn in the process of being transferred from the yarn tube to the warp beam with the bottom surface of the yarn guide wheel 3, so that the yarn can support the warp stop piece 21. Subsequently, when the yarn breaks, the warp stop piece 21 moves downward under the combined action of the elastic rope 4 and gravity, so that the bottom of the warp stop piece 21 contacts the control switch 2, and then the warping machine stops running, thereby reducing the difficulty of operation for the staff and improving the stability of the device.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
