Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a wire breakage detection device for a spinning machine. Background Art

[0002] During the spinning process, yarn breaks often occur when it is transported on the yarn tube to the spinning equipment. Since most textile workers operate multiple machines by one person, when the yarn on a yarn tube in a single device breaks, it is not easy for the operator to find it, resulting in the yarn at the yarn tube being unable to work normally for a long time, affecting the spinning quality and spinning speed.

[0003] Patent CN214572464U proposes a spinning machine wire breakage detection device, in which a laser spotlight is arranged on the rear wall of the spinning machine, and a mirror is arranged on the front wall of the spinning machine. The laser spotlight on the rear wall of the spinning machine is adjusted to illuminate the yarn. When the yarn on a certain yarn tube breaks, a reflective gap will appear at its work station, and the textile workers can see it from a long distance.

[0004] In the above scheme, the reflection of laser lights and mirrors is used to remind the staff of thread breakage. However, multiple groups of yarns are fed simultaneously on a threading row. Therefore, even after thread breakage occurs, the staff needs to find the location of the thread breakage and cannot immediately determine which yarn is broken. It is also not convenient for wiring. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a spinning machine wire breakage detection device to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. The yarn passes through the clamping frame in a taut state. When the wire breaks, the tensioning effect of the yarn disappears, and the clamping frame rises and protrudes from other positions, making it easier for the staff to find it, and can accurately give the location of the broken wire. Through the cooperation of the extrusion plate and the clamping frame, the broken wire part can also be clamped, which is convenient for subsequent rewiring.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a spinning machine wire breakage detection device, including a mounting frame, a plurality of groups of yarn tubes are equidistantly installed on the surface of the mounting frame, and yarns pass through the yarn tubes, a detection component is provided on the top of the back side of the yarn tube, and the detection component includes a fixed plate, a plug hole is opened on the surface of the fixed plate, and a slide rod slides through the plug hole of the fixed plate, a clamping frame is fixed on the top of the slide rod, the yarn passes through the wire groove in the clamping frame, an extrusion plate is provided at one end of the bottom of the clamping frame, and the extrusion plate can squeeze and fix the yarn, a wire row is fixed to the tail end of the mounting frame, and the wire row threading hole corresponds to the yarn tube straight line, and the yarn is tautly passed through the wire row and the yarn tube.

[0007] Furthermore, a movable notch is provided on the back of the mounting frame at the bobbin mounting position, and the slide rod passes through the movable notch.

[0008] Furthermore, the detection assembly also includes a first spring, the first spring is sleeved on the surface of the sliding rod, the bottom of the first spring is fixed to the sliding rod, and the top of the first spring is fixed to the fixing plate.

[0009] Furthermore, a ball is fixed at a position of the sliding rod corresponding to the insertion hole of the fixing plate, and the ball can pass through the insertion hole of the fixing plate.

[0010] Furthermore, guide rods are slidably sleeved on both sides of the extrusion plate, and the tops of the guide rods are fixed to the sides of the clamping frame. A second spring is sleeved on the surface of the guide rods, and both ends of the second spring are fixed to the extrusion plate and the clamping frame.

[0011] Furthermore, the fixed plate is symmetrically fixed with transverse plates on the surface of both sides of the plug hole, and a plug rack is slidably inserted in the transverse plate, a third spring is equidistantly fixed between the transverse plate and the plug rack, and the ball can be squeezed into contact with the plug rack.

[0012] Furthermore, a vertical column is fixed at the bottom of the extrusion plate, movable grooves are opened on both sides of the bottom of the vertical column, and an insert block is fixed at the position of the insert rack corresponding to the movable groove, and the insert block can be slidably inserted into the movable groove.

[0013] Furthermore, there is still a distance between the bottom of the movable groove and the bottom of the insert block.

[0014] Beneficial effects of the utility model: The utility model is a spinning machine wire breakage detection device, comprising a mounting frame; a movable notch; a yarn tube; yarn; a wire row; a detection assembly; a slide bar; a first spring; a fixed plate; a clamping frame; a squeezing plate; a guide rod; a second spring; a vertical column; a round ball; a horizontal plate; a plug-in frame; a third spring; a movable slot; an insert block;

[0015] After the inserting block is inserted, the movable groove still has a certain space, so when the clamping frame moves upward, before the ball pushes the inserting block out of the movable groove, a certain moving space is given to the inserting block to avoid movement interference.

[0016] In the process of the sliding rod driving the ball to move upward, the ball squeezes the insertion racks on both sides and compresses the third spring. At this time, the insertion rack separates the insertion block from the moving groove. In the absence of limiting measures, the squeezing plate rises along the guide rod under the elastic force of the second spring to cooperate with the clamping frame to clamp the broken wire part.

[0017] Before the yarn is broken, the utility model is in a taut conveying state. At this time, the first spring is stretched at the bottom of the fixed plate. Then, after the yarn is broken, the elastic force of the first spring bounces the slide bar upward, and the slide bar lifts the clamping frame, so that it is higher than other positions, which is convenient for staff to find and clearly locate the broken thread position.

[0018] Compared with the prior art, the utility model allows the yarn to pass through the clamping frame in a taut state. When a wire break occurs, the tensioning effect of the yarn disappears, and the clamping frame rises and protrudes from other positions, thereby being more easily discovered by the staff and accurately giving the position of the broken wire. Through the cooperation of the extrusion plate and the clamping frame, the broken wire part can also be clamped, which is convenient for subsequent rewiring. BRIEF DESCRIPTION OF THE DRAWINGS

A wire row 3 is fixed to the tail end of the mounting frame 1, and the threading hole of the wire row 3 corresponds to the yarn tube 2 in a straight line. The yarn 21 is stretched and passed through the wire row 3 and the yarn tube 2. When the device is used, the mounting frame 1 is installed on the spinning machine, and the yarn 21 is stretched and transported through the wire row 3 and the yarn tube 2. The yarn 21 passes through the clamping frame 44. When the wire breaks, the clamping frame 44 moves up to be higher than other positions, and cooperates with the squeezing plate 45 to fix the yarn 21, thereby facilitating subsequent wiring work.

[0027] In this embodiment, a moving notch 11 is provided on the back of the mounting frame 1 at the mounting position of the bobbin 2 , and the slide bar 41 passes through the moving notch 11 , so that the first spring 42 and the slide bar 41 can be easily moved through the moving notch 11 .

[0028] In this embodiment, the detection component 4 also includes a first spring 42, the first spring 42 is sleeved on the surface of the slide bar 41, and the bottom of the first spring 42 is fixed to the slide bar 41, and the top of the first spring 42 is fixed to the fixed plate 43, and the slide bar 41 is fixed with a ball 49 at the position corresponding to the insertion hole of the fixed plate 43, and the ball 49 can pass through the insertion hole of the fixed plate 43. Before the thread is broken, the yarn 21 is in a taut conveying state. At this time, the first spring 42 is stretched at the bottom of the fixed plate 43, and then after the yarn 21 breaks, the elastic force of the first spring 42 bounces the slide bar 41 upward, and the slide bar 41 lifts the clamping frame 44, so that it is higher than other positions, which is convenient for the staff to find and find the clear position of the broken thread.

[0029] In this embodiment, guide rods 46 are slidably sleeved on both sides of the extrusion plate 45, and the top of the guide rods 46 is fixed to the side of the clamping frame 44, and a second spring 47 is sleeved on the surface of the guide rods 46, and the two ends of the second spring 47 are fixed to the extrusion plate 45 and the clamping frame 44, and the fixed plate 43 is symmetrically fixed with transverse plates 410 on the surface of both sides of the insertion hole, and a plug-in rack 411 is slidably inserted in the transverse plate 410, and a third spring 412 is equidistantly fixed between the transverse plate 410 and the plug-in rack 411, and the ball 49 can be pressed and contacted with the plug-in rack 411, and the bottom of the extrusion plate 45 is fixed with a vertical column 48, and the vertical column 4 Movable grooves 413 are provided on both sides of the bottom, and plug blocks 414 are fixed at positions of the inserting rack 411 corresponding to the movable grooves 413, and the plug blocks 414 can be slidably inserted into the movable grooves 413. When the sliding rod 41 drives the ball 49 to move upward, the ball 49 squeezes the inserting racks 411 on both sides and compresses the third spring 412. At this time, the inserting rack 411 separates the plug blocks 414 from the movable grooves 413. In the absence of limiting measures, the squeezing plate 45 rises along the guide rod 46 under the elastic force of the second spring 47 to cooperate with the clamping frame 44 to clamp the broken wire part (this method is limited to the case where the wire breaks at a position far away from the clamping frame 44).

After the insert block 414 is inserted, the movable groove 413 still has a certain space, so that when the clamp frame 44 moves up, before the ball 49 pushes the insert block 414 out of the movable groove 413, a certain movement space is given to the insert block 414 to avoid movement interference.

[0031] When the device is used, the mounting frame 1 is installed on the spinning machine, and the yarn 21 is tightened and transported through the conductor row 3 and the bobbin 2. The yarn 21 passes through the clamping frame 44. Before the yarn 21 is broken, the yarn 21 is in a tightened and transported state. At this time, the first spring 42 is stretched at the bottom of the fixed plate 43. Then, after the yarn 21 breaks, the elastic force of the first spring 42 bounces the slide bar 41 upward, and the slide bar 41 lifts the clamping frame 44, so that it is higher than other positions, which is convenient for staff to find and find a clear broken line position. In the process of the slide bar 41 driving the ball 49 to move upward, the ball 49 squeezes the two side brackets 411 and compresses the third spring 412. At this time, the bracket 411 disengages the plug 414 from the movable groove 413. In the absence of limiting measures, the squeeze plate 45 rises along the guide rod 46 under the elastic force of the second spring 47 and cooperates with the clamping frame 44 to clamp the broken line position.
