Description

Technical Field

[0001] This utility model relates to the field of polyester-nylon composite microfiber production technology, specifically a feed-stopping device for automatically stopping the production of polyester-nylon composite microfiber. Background Technology

[0002] Polyester-nylon composite microfiber is an extended product of nylon / polyester composite yarn. The microfiber monofilament is 1 / 20 of that of ordinary fiber. After special processing and finishing, the fabric is fluffy and soft, with a large specific surface area and abundant capillary effect. After the fiber bundle is bundled and oiled, it enters the drawing machine for stretching. During this process, the drawing machine may break the fiber bundle. At this time, an automatic stop feeding device is needed to prevent the fiber bundle from continuing to be transported.

[0003] In the prior art, patent publication number CN201921301593.X discloses an automatic stop feeding device for broken roving in a spinning frame with a round rod type adjustable gear, including a housing and a spinning frame main unit used in conjunction with the device; a sliding plate is slidably disposed inside the housing, and the sliding plate extends outside the housing; the spinning frame has a spinning frame cradle, a spinning frame cradle support rod, a spinning frame rear roller, a spinning frame rear rubber roller, a spinning frame middle roller, and a spinning frame middle rubber roller, the spinning frame rear roller being located below the spinning frame rear rubber roller, and the spinning frame middle roller being located below the spinning frame middle rubber roller; one or more parallel rectangular grooves are opened in the sliding plate, and several round rods are evenly inserted through the rectangular grooves;

[0004] The aforementioned automatic stop feeding device has some problems in actual use. For example, when the roving is clamped between the rear roller and the rear skin roller of the spinning machine, there is no buffer structure. When clamping the roving, the yarn bundle may be torn, affecting subsequent processing operations. To address this, we propose an automatic stop feeding device for the production of polyester-nylon composite microfiber. Utility Model Content

The upper and lower surfaces of the anti-feeding frame are respectively provided with evenly distributed protective grooves. The upper and lower surfaces of the four sliders are provided with protective plates. The outer surfaces of the eight protective plates are respectively slidably connected to the interior of the protective grooves located in the same position to achieve the function of stable driving.

[0012] Furthermore, the drive mechanism includes a synchronous pulley, a synchronous belt, an adjusting pulley, and a motor. The synchronous pulleys are fixedly connected to the right ends of the two lead screws on the right side. The right side of the anti-feeding frame is symmetrically connected to the adjusting pulleys via a rotating shaft.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This embodiment provides a technical solution: an automatic stop feeding device for the production of polyester-nylon composite microfiber, including a stop feeding frame 1, an energy-consuming braking mechanism 2 and a drive mechanism 3;

[0024] Feed stop frame 1: Guide cylinders 5 are provided on its left and right sides respectively. A controller 10 is provided on the outside of the feed stop frame 1. The input end of the controller 10 is electrically connected to an external power supply. Mounting feet 9 are symmetrically fixedly connected to the front and rear sides of the feed stop frame 1 respectively. Bolt slots are opened on the upper surface of the four mounting feet 9 respectively. The bolt slots are used to install the feed stop frame to the designated work position by external bolts. When the feed stop device is needed, the unprocessed fiber 6 can be drawn out from the spinneret of the spinning box and then guided into the feed stop frame 1 from the guide cylinder 5 on the right side. Then, it passes through two guide rollers and four guide rollers 28 in sequence according to the designated trajectory, and then passes out from the guide cylinder 5 on the left side and connects to the external fiber drawing machine. At this time, whenever the fiber 6 in the drawing machine is stretched and the fiber 6 breaks, it needs to be automatically stopped.

[0025] Energy-saving braking mechanism 2: It includes slide grooves 21, sliders 22, fixed seats 24, push rods 25, spacing adjustment frames 26, parts mounting frames 27, and guide rollers 28. Slide grooves 21 are respectively opened on the upper surface of the feed stop frame 1. Sliders 22 are slidably connected inside the four slide grooves 21. Fixed seats 24 are fixedly connected to the upper and lower surfaces of the four sliders 22. Push rods 25 are rotatably connected inside the eight fixed seats 24. A spacing adjustment frame 26 is rotatably connected to the upper end of the four upper push rods 25 and the lower end of the four lower push rods 25. Evenly distributed parts mounting frames 27 are fixedly connected to the opposite inner surfaces of the two spacing adjustment frames 26. Guide rollers 28 are provided inside the four parts mounting frames 27. Structure 2 also includes lead screws 23 and protective plates 29. The lead screws 23 are rotatably connected to the interior of four slide grooves 21. The thread directions of the two lead screws 23 on the left and the two lead screws 23 on the right are opposite. Each pair of horizontally adjacent lead screws 23 are fixedly connected. The upper and lower surfaces of the anti-feeding frame 1 are respectively provided with evenly distributed protective grooves 8. The upper and lower surfaces of the four sliders 22 are each provided with protective plates 29. The length of the protective plate 29 is half the length of the protective groove 8, and the thickness of the protective plate 29 is equal to the depth of the protective groove 8. Whenever the fixed seat 24 moves left and right in the slide groove 21, the protective plate 29 will seal the slide groove 21, effectively preventing the lead screws 23 in the slide groove 21 from being contaminated. The outer surfaces of the eight protective plates 29 are respectively connected to the inner surfaces of the slide grooves 21. The internal sliding connection of the protective groove 8 at one position is provided. Two adjustable brackets 26 are symmetrically fixedly connected to limiting telescopic rods 4 on their respective inner sides. The telescopic ends of the four limiting telescopic rods 4 are fixedly connected to the outer surface of a feed stop frame 1. The feed stop frame 1 also includes guide rods 7, which are symmetrically rotatably connected between the front and rear inner walls of the feed stop frame 1. Guide wheels are fixedly connected to the middle portions of the two guide rods 7. Fiber threads 6 are provided inside the two guide wheels, and the outer surfaces of the fiber threads 6 are slidably connected to the inside of the grooves of the four guide rollers 28. Tension gauges 11 are symmetrically provided on the left and right sides of the front side of the feed stop frame 1. The output shafts of the two tension gauges 11 are fixedly connected to the front ends of the longitudinally adjacent guide rods 7 (the tension gauges 11 measure the left and right guide rods 7 in real time). The tension prevents the polyester-nylon composite microfiber from being torn, thereby driving the four sliders 22 on the left and the four sliders 22 on the right to move closer and further apart synchronously. This, in turn, causes the upper and lower spacing adjustment frames 26 to move closer and further apart via eight push rods 25. This, in turn, causes the upper and lower guide rollers 28 to move closer and further apart. Whenever feeding needs to be stopped, the upper and lower guide rollers 28 can be moved further apart, thus changing the trajectory of the fiber thread 6. At this time, the four guide rollers 28 lengthen the trajectory of the fiber thread 6, and the spinning box slows down the output frequency of the fiber thread 6. During this process...The four guide rollers 28 slow down the output speed of the fiber 6, and as the fiber 6 is stretched, it stops being fed out of the guide cylinder 5 on the left, preventing it from continuing to be fed into the drawing machine, thus completing the automatic feed stop function of the fiber 6.

[0026] Drive mechanism 3: It is located on the outer side of the anti-feeding frame 1. The drive mechanism 3 is fixedly connected to the energy-consuming braking mechanism 2. The drive mechanism 3 includes a synchronous pulley 31, a synchronous belt 32, an adjusting pulley 33 and a motor 34. The synchronous pulley 31 is fixedly connected to the right end of the two lead screws 23 on the right side. The right side of the anti-feeding frame 1 is symmetrically connected to the adjusting pulley 33 by a rotating shaft. The two synchronous pulleys 31 and the two adjusting pulleys 33 are connected by a synchronous belt 32. The front side of the left side of the anti-feeding frame 1 is provided with a motor 34. The output shaft of the motor 34 is fixedly connected to the left end of the lead screw 23 on the left front side. The input end of the motor 34 is electrically connected to the output end of the controller 10, so that the controller 10 can be controlled. When the motor 34 is running, the output shaft of the motor 34 rotates, thereby driving the lead screw on the left front side to rotate in both directions. Then, through the synchronous pulley 31, the synchronous belt 32 and the adjusting pulley 33, the lead screw 23 on the rear side rotates synchronously in both directions.

[0027] The working principle of the automatic stop feeding device for polyester-nylon composite microfiber production provided by this utility model is as follows: When the stop feeding device is needed, the unfinished fiber thread 6 can be drawn out from the spinneret of the spinning box, and then guided into the stop feeding frame 1 from the guide tube 5 on the right. Then, it passes through two guide rollers and four guide rollers 28 in sequence according to the specified trajectory, and then passes out from the guide tube 5 on the left and connects to the external fiber thread drawing machine. At this time, whenever the fiber thread 6 in the drawing machine is stretched, causing the fiber thread 6 to break, and automatic stopping is required, the controller 10 can be adjusted to operate the motor 34. When the motor 34 operates, the output shaft of the motor 34 rotates, thereby driving the lead screw on the left front side to rotate in both directions. This, in turn, drives the lead screw 23 on the rear side to rotate in both directions synchronously through the synchronous pulley 31, synchronous belt 32 and adjusting pulley 33, thereby driving the four sliders 2 on the left side to rotate in both directions. 2. The four sliders 22 on the right side move closer and further apart in sync. This causes the eight push rods 25 to pull the upper and lower spacing adjustment frames 26 closer and further apart, which in turn drives the upper and lower guide rollers 28 to move closer and further apart. Whenever it is necessary to stop feeding, the upper and lower guide rollers 28 can be moved further apart, which changes the trajectory of the fiber thread 6. The four guide rollers 28 lengthen the trajectory of the fiber thread 6, and the spinning box slows down the output frequency of the fiber thread 6. During this process, the four guide rollers 28 slow down the output speed of the fiber thread 6, and as the fiber thread 6 is lengthened, it is no longer fed out from the guide cylinder 5 on the left side, preventing the fiber thread 6 from continuing to be fed into the interior of the drawing machine, thus completing the function of automatic feed stop of the fiber thread 6.

[0028] It is worth noting that the core chip of the controller 10 disclosed in the above embodiments is a microcontroller, specifically the STM32. The motor 34 and tension meter 11 can be freely configured according to the actual application scenario. It is recommended that the motor 34 be a 130BL servo motor, and the tension meter 11 be a DTF-25-250G tension meter for yarn textiles. The microcontroller or PLC controller controls the operation of the motor 34 using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
