Description

Technical Field

[0001] The present application relates to the technical field of yarn processing, and in particular to a yarn breakage prevention device. Background Art

[0002] Yarn is a textile product that is processed into a certain fineness from various textile fibers and used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. During the weaving process, the yarn will experience multiple stretching and bending. These mechanical stresses may cause yarn fatigue and then breakage. In particular, when the yarn passes through various guides, rollers or tension devices, if these components are improperly set (such as too much or too little tension), it may also cause the yarn to break. Therefore, during the yarn transmission process, sensors and control systems are generally installed to detect the tension and movement state of the yarn, such as the Chinese patent with publication number CN110723592A, a yarn transmission anti-breakage device.

[0003] At present, when the yarn is transmitted, the set wire wheel generally provides a tension within the allowable range for yarn transmission to avoid yarn breakage. However, during continuous transmission, the yarn will still be short-wired. After the yarn breaks, the thread ends at both ends will suddenly lose tension, causing the thread ends to break directly. This requires the staff to find the thread ends again in the transmission equipment and install them before continuing to transmit, which is inconvenient. Therefore, in order to solve the problem of inconvenient reinstallation, a yarn square breaking device is designed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a yarn breakage prevention device. Figure 1-4 , a yarn anti-breaking device, comprising a mounting frame 1, a PLC controller 2 is installed at the front of one side of the mounting frame 1, two conveying rollers 3 symmetrically arranged up and down are rotatably installed on both sides of the mounting frame 1, a yarn wheel 4 is rotatably installed at the lower end of the middle part of the mounting frame 1, a support plate 5 is installed at the front of the yarn wheel 4, the lower end of the support plate 5 is fixedly connected to the mounting frame 1, and a tension sensor 12 is installed at the front of the support plate 5. The tension sensor 12, the PLC controller 2 and the yarn wheel 4 can refer to the Chinese patent with publication number CN110723592A, a yarn transmission anti-breaking device;

[0022] The half gears 6 are rotatably connected to both sides of the middle of the mounting frame 1, and the middle of the front side of the half gear 6 is fixedly connected to the fixing rod 61. A slide groove is provided on the lower side of the front of the half gear 6, and a limit rod 62 is slidably connected in the slide groove. The limit rod 62 and the fixing rod 61 are metal cylinders to reduce the friction of the yarn. One side of the half gear 6 is meshed with the gear plate 7, and the upper ends of the gear plates 7 are fixedly connected to the fixing plate 8 on one side close to each other. When the gear plate 7 is lowered, the gear plate 7 drives the half gear 6 to rotate, so that the half gear 6 rotates with its own center of circle as the axis, and drives the limit rod 62 on one side to rotate, so that the limit rod 62 drives the yarn to wrap around the fixing rod 61, thereby fixing the two ends of the disconnected yarn, preventing the yarn from falling to a position that is inconvenient to find in the transportation equipment, and facilitating the reinstallation of the yarn.

[0023] By adopting the above technical solution, in order to facilitate the installation of yarn, the yarn passes between the limit rod 62 and the fixed rod 61, and the slider 621 is fixedly connected to the rear of the limit rod 62, and the slider 621 is slidably connected to the slide groove, and the pull rod 623 is fixedly connected to one side of the slider 621, and the spring 622 is fixedly connected to the side wall of the slide groove. Pull the pull rod 623 on one side to make the pull rod 623 first drive the limit rod 62 away from the fixed rod 61, and then pass the yarn between the two. After passing through, the spring 622 drives the limit rod 62 to recover and clamp the yarn.

[0024] By adopting the above technical scheme, the upper end of the fixed plate 8 is fixedly connected to the No. 1 elastic sheet 9, the upper end of the No. 1 elastic sheet 9 is fixedly connected to the mounting plate 10, and the rear part of the mounting plate 10 is fixedly connected to the mounting frame 1. In the initial state, the No. 1 elastic sheet 9 is in a compressed and contracted state, and the two sides of the upper end of the fixed plate 8 are fixedly connected to the plug rods 81, and the upper ends of the plug rods 81 are plugged into the mounting plate 10. The mounting plate 10 is plugged by the plug rods 81 to fix the fixed plate 8 and the gear plate 7, and the No. 1 elastic sheet 9 is squeezed and contracted.

[0025] By adopting the above technical solution, a fixing groove is opened on one side of the insertion rod 81, and the second elastic piece 82 is fixedly connected in the fixing groove. One side of the second elastic piece 82 is fixedly connected to the clamping block 83, and the clamping block 83 clamps the mounting plate 10.

[0026] By adopting the above technical solution, electromagnets 11 are installed on both sides of the upper end of the mounting plate 10. One side of the electromagnet 11 is electrically connected to the battery. When the battery is energized, the electromagnet 11 becomes magnetic, thereby facilitating the adsorption of the card block 83 into the fixing groove.

[0027] The implementation principle of the yarn anti-breaking device of the embodiment of the present application is as follows: one end of the yarn passes through between the conveying rollers 3, and then the pull rod 623 on one side is pulled, so that the pull rod 623 first drives the limiting rod 62 away from the fixed rod 61, and then the yarn passes between the two. After passing through, the spring 622 drives the limiting rod 62 to recover and clamp the yarn, and then passes around the bottom of the yarn wheel 4 to transmit the yarn. Figure 1 As shown, when the tension sensor 12 detects that the yarn is reduced instantly and infers that the two ends of the yarn are disconnected, the PLC controller 2 controls the battery to energize the electromagnet 11, so that the electromagnet 11 generates magnetic attraction on one side of the block 83 after being energized, so that the block 83 is attracted into the fixed groove, and the second elastic sheet 82 is squeezed to contract, so that the block 83 is no longer clamped on the mounting plate 10. At this time, the lower end of the elastic sheet 9, which is always in a compressed state, provides thrust to push the fixed plate 8, so that the fixed plate 8 drives the gear plates 7 on both sides to descend, and the gear plate 7 drives the half gear 6 to rotate, so that the half gear 6 rotates with its own center of circle as the axis, and drives the limiting rod 62 on one side to rotate, so that the limiting rod 62 drives the yarn to wrap around the fixed rod 61, thereby fixing the two ends of the disconnected yarn, preventing the yarn from falling to an inconvenient position in the transportation equipment, and facilitating the reinstallation of the yarn.
