Description

Technical Field

[0001] This utility model relates to the field of yarn textile technology, specifically to a yarn drawing frame. Background Technology

[0002] Yarn spinning is the entire process of processing natural or chemical fibers into yarn, and then making fabrics through weaving, knitting and other processes. In the process of yarn spinning, in order to improve the structure and performance of the yarn, a yarn drawing frame is usually used to improve the structure and performance of the yarn by combining and stretching multiple fiber strips.

[0003] When using existing yarn drawing frames, the operator usually feeds the fiber sliver into the drawing frame through the guide rollers and the inlet. After the fiber sliver is stretched by the stretching rollers, it is discharged through the outlet and falls into the collection bin. When the sliver bin is full, the operator uses a cutting knife to cut the fiber sliver.

[0004] Existing yarn drawing frames have the following problems: when collecting fiber slivers, workers need to observe nearby. When the sliver can is full, a cutting knife is needed to cut the fiber slivers. During the work process, workers may become distracted and fail to cut the fiber slivers in time, thus affecting the normal operation of yarn drawing. To address this, we propose a textile yarn drawing frame. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a textile yarn drawing frame. When the cotton sliver can is full, the fiber sliver is cut in time by the cutting mechanism, which avoids the situation where the drawing work of the yarn is affected due to the worker's inattention and failure to cut the fiber sliver in time. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn drawing frame, including a drawing frame, wherein a placement cavity is provided on the front side of the drawing frame, and a cutting mechanism is also included;

[0007] The cutting mechanism includes a rotating shaft, a connecting rod, a limiting rod, a limiting track, a push plate, a cutting blade, a barrier plate, and a limiting assembly. A slot is formed in the rear wall of the placement cavity. A rotating shaft is rotatably connected to the bottom wall of the slot. A connecting rod is located at the upper end of the rotating shaft. A limiting rod is located on the upper surface of the connecting rod away from the rotating shaft. A push plate is slidably connected to the inside of the slot via the limiting assembly. A limiting track is located on the rear side of the push plate. A limiting rod is slidably connected to the inside of the limiting track. A cutting blade is located on the front side of the push plate. A barrier plate is located on the top wall of the placement cavity. When the cotton sliver can is full, the cutting mechanism promptly cuts the fiber sliver, preventing the yarn drawing process from being affected by the worker's inattention in not cutting the fiber sliver in time.

[0008] Furthermore, it also includes a microcontroller, which is fixedly connected to the front side of the folding machine. The input terminal of the microcontroller is electrically connected to an external power supply, and the input terminal of the folding machine is electrically connected to the output terminal of the microcontroller, which facilitates the normal operation of the equipment.

[0009] Furthermore, a motor is provided on the rear side of the slitting machine. The upper end of the output shaft of the motor is fixedly connected to the lower end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0010] Furthermore, the limiting component includes ribs and rib grooves. Ribs are provided on both the left and right sides of the push plate, and rib grooves are provided on both the left and right walls of the groove. The ribs are slidably connected to the inside of the rib grooves on the same side, which facilitates the sliding limiting of the push plate.

[0011] Furthermore, the cutting mechanism also includes a photoelectric sensor. A photoelectric sensor is provided on the upper left wall of the placement cavity. The horizontal height of the photoelectric sensor is lower than that of the cutting blade. The photoelectric sensor is bidirectionally electrically connected to the microcontroller, which makes it easy to know when the fiber strip is full.

[0012] Furthermore, it also includes a stretching roller assembly, which includes a traction roller, a support roller, and a positioning roller. A stretching cavity is provided on the upper side of the slat frame. The traction roller, support roller, and positioning roller are rotatably connected to both sides of the stretching cavity. The traction roller is located on the front side. There are three support rollers in one stretching roller assembly, located in the middle. There are two positioning rollers in one stretching roller assembly, located on the rear side and symmetrically distributed vertically. There are two motors on both the left and right sides of the slat frame. The output shaft of the motor is fixedly connected to the end of the traction roller on the same side away from the center of the slat frame. The input end of the motor is electrically connected to the output end of the microcontroller to facilitate stretching and pulling the fiber slat.

[0013] Furthermore, the rear side of the sliver splitter is provided with inlet ports on both the left and right sides. The front end of the inlet port is cylindrical, and the rear end of the inlet port is flared, narrow at the front and wide at the back. The top wall of the placement chamber is provided with outlet ports on both the left and right sides to facilitate the passage of fiber slivers.

[0014] Furthermore, the rear side of the sizing machine is provided with a support frame, and the left and right sides of the support frame are rotatably connected with evenly distributed guide rollers. The left and right sides of the upper front surface of the support frame are rotatably connected with evenly distributed separator cylinders, which facilitates the simultaneous guidance of multiple yarns.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This yarn drawing frame has the following advantages:

[0016] Once the photoelectric sensor detects that the fiber sliver is full, the rotating shaft rotates, which in turn drives the limiting rod to rotate around the rotating shaft via the connecting rod. As the limiting rod rotates, it slides within the limiting track. The limiting rod, through the limiting track, drives the push plate to slide, and the push plate drives the cutting knife to move until the combined action of the cutting knife and the blocking plate cuts the fiber sliver. The timely cutting mechanism prevents the yarn drawing process from being affected by workers' inattention and failure to cut the fiber sliver in time. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-6This embodiment provides a technical solution: a yarn drawing frame, including a drawing machine 1, a placing cavity on the front side of the drawing machine 1, a cutting mechanism 3, and a single-chip microcomputer 2, which is fixedly connected to the front side of the drawing machine 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power source, and the input end of the drawing machine 1 is electrically connected to the output end of the single-chip microcomputer 2. It also includes a tension roller group 5, which includes a traction roller 51, a support roller 52, and a positioning roller 53. A tension cavity is provided on the upper side inside the drawing machine 1. The traction roller 51, support roller 52, and positioning roller 53 are rotatably connected to both sides of the tension cavity. The traction roller 51 is located on the front side. The support roller 52 of one tension roller group 5 consists of three rollers located in the middle, and the positioning roller 53 of one tension roller group 5 consists of two rollers. Each motor 6 is symmetrically distributed on the rear side. Inside the folding machine 1, motors 6 are located on both the left and right sides. The output shaft of motor 6, near the center of the folding machine 1, is fixedly connected to the end of the traction roller 51 on the same side, away from the center of the folding machine 1. The input ends of motors 6 are electrically connected to the output end of the microcontroller 2. Inlet ports 7 are located on both the left and right sides of the rear side of the folding machine 1. The front end of inlet port 7 is cylindrical, and the rear end is flared, narrower at the front and wider at the back. Outlet ports 8 are located on both the left and right sides of the top wall of the placement chamber. (The outlet ports 8 of the folding machine 1 are equipped with a bundler and a coiler. The main function of the bundler is to gather the drawn fiber bundles into a tight, uniform fiber strip, reducing fiber diffusion and improving the quality of the strip. The bundler consists of a main frame and a bundler channel.) The main frame of the coiler is usually made of metal or engineering plastic and is fixed between the traction roller and the coiler, supporting the internal components. The bundling channel is mostly funnel-shaped or narrow slit-shaped, with a wide inlet and a narrow outlet, guiding the fiber bundle to gradually contract and gather as it passes through. The coiler is mainly used to regularly coil the fiber slivers after traction and bundling processes into the sliver can for easy transportation, storage, and use in the next process. The coiler consists of a transmission part, a coiling disc, a base, and sliver inlet and outlet. The coiling disc rotates at high speed. When the fiber sliver enters the inclined tube inside the coiling disc from the sliver inlet, under the action of centrifugal force, the fiber sliver is thrown towards the outer wall of the inclined tube. At the same time, under the influence of gravity, the fiber sliver gradually moves downward along the inclined tube. The coiling disc rotates at high speed, while the sliver can... The sliver remains stationary, allowing the fiber sliver ejected from the coiling disc to form a regular shape, tightly arranged in concentric circles within the sliver can. A support frame 9 is located on the rear side of the sliver folding machine 1. Guide rollers 10 are rotatably connected to both sides of the support frame 9, and divider cylinders 11 are rotatably connected to both sides of the upper front surface of the support frame 9. The operator places the sliver can into the placement chamber on the front side of the sliver folding machine 1, then simultaneously passes multiple yarns around the upper side of the corresponding guide rollers 10. The yarns are then distributed and passed between the corresponding two divider cylinders 11, and finally all the yarns are passed through the sliver inlet 7. They then pass between the two positioning rollers 53, around the upper side of the support roller 52 and the traction roller 51, and the sliver is drawn inside the sliver folding machine 1.The yarn is combined into a fiber sliver through the combined action of the bundler and coiler, and finally falls into the sliver can through the exit port 8. The operator turns on motor 6, and the output shaft of motor 6 drives the traction roller 51 to rotate and pull the yarn.

[0026] Cutting mechanism 3: It includes a rotating shaft 31, a connecting rod 32, a limiting rod 33, a limiting track 34, a push plate 35, a cutting blade 36, a blocking plate 37, and a limiting assembly 38. A slot is formed in the rear wall of the placement cavity. The bottom wall of the slot is rotatably connected to the rotating shaft 31. The upper end of the rotating shaft 31 is provided with the connecting rod 32. A limiting rod 33 is provided on the upper surface of the connecting rod 32 away from the rotating shaft 31. The inside of the slot is slidably connected to the push plate 35 via the limiting assembly 38. The rear side of the push plate 35 is provided with the limiting track 34. The limiting rod 33 slides... The push plate 35 is connected to the inside of the limiting track 34. The front side of the push plate 35 is provided with a cutting blade 36. The top wall of the placement cavity is provided with a baffle plate 37. The rear side of the inside of the folding machine 1 is provided with a motor 4. The upper end of the output shaft of the motor 4 is fixedly connected to the lower end of the rotating shaft 31. The input end of the motor 4 is electrically connected to the output end of the microcontroller 2. The limiting component 38 includes ribs 381 and rib grooves 382. Ribs 381 are provided on both the left and right sides of the push plate 35. Ribs 382 are provided on both the left and right walls of the groove. The ribs 381 are slidably connected to the same side. Inside the rib groove 382, ​​the cutting mechanism 3 also includes a photoelectric sensor 39. The photoelectric sensor 39 is located on the upper left wall of the placement cavity. The horizontal height of the photoelectric sensor 39 is lower than that of the cutting blade 36. The photoelectric sensor 39 is bidirectionally electrically connected to the microcontroller 2. The detection head of the photoelectric sensor 39 contains a light emitter and a light receiver. When the yarn is full, it will continuously block the light and reflect part of the light back. The light receiver receives the light signal and transmits it to the microcontroller 2, which then controls the motor 4 to work. The output shaft of the motor 4 drives... The rotating shaft 31 rotates, and the rotation of the rotating shaft 31 drives the limiting rod 33 to rotate around the rotating shaft 31 through the connecting rod 32. While the limiting rod 33 rotates, it slides in the limiting track 34. Under the restriction of the rib 381 and the rib groove 382, ​​the limiting rod 33 drives the push plate 35 to slide along the groove through the limiting track 34. The push plate 35 drives the cutting knife 36 to move until the combined action of the cutting knife 36 and the blocking plate 37 cuts the fiber strip. Then the worker can replace the full cotton sliver tube with a new one to continue the sliver drawing work.

[0027] The working principle of the yarn drawing frame provided by this utility model is as follows: The operator places the sliver can in the placement cavity at the front of the drawing frame 1, then multiple yarns simultaneously pass over the upper side of the corresponding guide rollers 10, then the yarns are distributed and passed between the corresponding two separators 11, then all the yarns pass through the inlet 7, then pass between the two positioning rollers 53, pass over the upper side of the support roller 52 and the traction roller 51, and the drawing process is carried out inside the drawing frame 1. Through the combined action of the bundler and coiler of the drawing frame 1, the yarns are combined into fiber slivers, and finally fall into the sliver can through the outlet 8. The operator turns on the motor 6, and the output shaft of the motor 6 drives the traction roller 51 to rotate and pull the yarn. The detection head of the photoelectric sensor 39 is equipped with... A light emitter and a light receiver work together. When the yarn is full, the light emitter blocks the light and reflects some of it back. The light receiver receives the light signal and transmits it to the microcontroller 2, which then controls the motor 4. The output shaft of the motor 4 drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the limiting rod 33 to rotate around the rotating shaft 31 via the connecting rod 32. While rotating, the limiting rod 33 slides in the limiting track 34. Under the restriction of the ribs 381 and the rib grooves 382, ​​the limiting rod 33 drives the push plate 35 to slide along the groove through the limiting track 34. The push plate 35 drives the cutting knife 36 to move until the combined action of the cutting knife 36 and the blocking plate 37 cuts the fiber sliver. Then, the worker can replace the full cotton sliver can with a new one to continue the drawing process.
