Description

Technical Field

[0001] The present invention relates to the technical field of spinning machinery, and particularly to a drawing frame for spinning processing. Background Art

[0002] A drawing frame is used to process fiber slivers through operations such as doubling and drafting to improve the evenness of the slivers and the straightening and parallelism of the fibers, providing semi-finished products with good quality for subsequent spinning processes. However, during the operation of the drawing frame, the slivers in the sliver cans will continuously decrease with production. When the slivers in the working sliver can are nearly used up, the operator needs to quickly remove the empty can, accurately place the pre-prepared spare sliver can at the corresponding position of the can, and complete the knotting or twisting connection of the working sliver and the spare sliver. This operation process is highly dependent on the staff. It requires the staff to accurately judge the remaining amount of slivers in the can and replace the can in a timely manner. If the can is replaced in advance when there is still a large amount of slivers remaining, the unused slivers will be randomly wound because they are separated from the original winding structure in the can, not only causing waste of raw materials, but also resulting in breakage during transportation due to the entanglement of the slivers, forcing the equipment to stop for processing. If the can is not replaced in time when the remaining amount is small, the exhaustion of the slivers will cause the equipment to be forced to stop and wait, thus affecting the continuity and production efficiency of the drawing process. In view of the above problems, the inventor proposes a drawing frame for spinning processing to solve the above problems. Summary of the Invention

[0003] In order to solve the problem that the operation of replacing the sliver can and controlling the timing during the operation of the drawing frame highly depends on the inspection by the staff and is difficult to operate; the purpose of the present invention is to provide a drawing frame for spinning processing.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: A drawing frame for spinning processing, including an equipment frame.

The first motor is fixedly installed at the lower part of the equipment frame. The middle parts of the bottoms of the plurality of driving disks are fixedly installed on the driving ends of the first motor.

[0006] Preferably, the conveying mechanism includes conveying frames. Four conveying frames are provided and are symmetrically distributed. The four conveying frames are fixedly installed on one side of the upper part of the equipment frame. Two groups of symmetrically distributed conveying rollers are rotatably installed in the middle of each of the four conveying frames. First gears are fixedly installed on one side of each group of conveying rollers and are meshed with each other. Two symmetrically distributed second rotating shafts are provided on the upper part of the equipment frame. Both ends of the two second rotating shafts are fixedly installed in the middle of one side of the first gears; Two symmetrically distributed first rotating shafts are rotatably installed on one side of the upper part of the equipment frame. One end of one of the first rotating shafts is fixedly installed with a transmission roller. One end of the other first rotating shaft is rotatably installed at one end of the transmission roller. A second crown gear is fixedly installed at one end of the transmission roller. A first crown gear is provided on one side of the lower part of the second crown gear. The first crown gear is meshed with the second crown gear. A second motor is fixedly installed on one side of the upper part of the equipment frame. The middle part of the bottom of the first crown gear is fixedly installed on the driving end of the second motor. Two symmetrically distributed rotating blocks are fixedly installed on the outer surface of one of the first rotating shafts. Both of the two rotating blocks slidably penetrate through the middle parts of the driven blocks; On one side of the driving roller, a plurality of clamping blocks are fixedly installed. In the middle of one side of another first rotating shaft, a driven block that cooperates with the clamping blocks is slidably clamped. On one side of the driven block, a moving plate is rotatably installed. On the upper side of the equipment frame, an electric push rod is fixedly installed.

In the middle of one side of both first rotating shafts, fourth crown gears are fixedly installed. In the middle of both second rotating shafts, third crown gears are fixedly installed, and the third crown gears are meshed with the corresponding fourth crown gears. The two groups of third crown gears and fourth crown gears are mirror-symmetrically distributed, and the tooth number ratios of the third crown gears and the fourth crown gears are different.

[0007] Preferably, a plurality of uniformly distributed fixing plates are fixedly installed on the upper part of the equipment frame. On one side of each of the plurality of fixing plates, a mounting frame is fixedly installed. At the lower part of each of the plurality of mounting frames, a guiding tube is rotatably installed.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this application, the usage situation of the sliver is monitored by sensors. When the end of the sliver breaks away, the control platform controls the first motor to make the rotating disk rotate intermittently, automatically switching between the empty bobbin and the full bobbin, which speeds up the replacement speed of the staff. It enables the staff to install the spare bobbin in advance and place it at the designated position. At the same time, there is no need for manual control of the bobbin changing timing, reducing the operation difficulty. 2. In this application, through the mutual cooperation of the second motor and the electric push rod, the sliver to be drawn can be conveyed. And through the crown gear assemblies with different tooth number ratios to form a speed difference, during the conveying process of the sliver, part of the sliver will be retained in the middle of the conveying rollers on both sides. When changing the bobbin, the retained sliver is used to maintain the operation of the drawing frame, ensuring that the connection of the sliver can be completed without stopping the equipment, significantly improving the production efficiency. 3. In this application, the position of the clamping block is adjusted by rotating the screw rod, thereby clamping and fixing the bobbin, effectively avoiding the problems of breakage or entanglement of the sliver caused by the shaking of the bobbin during the conveying process of the sliver, improving the processing accuracy. At the same time, through the settings of the limiting frame and the guiding tube, it can limit the sliver when it is pulled out from the bobbin for conveying, reducing the risk of entanglement with other slivers or breakage of the sliver caused by the excessive swing amplitude of the sliver.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment: As Figure 1-8 shown, the present invention provides a draw frame for spinning processing, which includes an equipment frame 1. A plurality of evenly distributed feeding mechanisms 2 are provided at the lower part of the equipment frame 1. A conveying mechanism 3 for conveying the sliver is provided on one side of the upper part of the equipment frame 1. A draw frame device 4 for draw frame processing of the sliver is fixedly installed on one side of the equipment frame 1.

[0021] The feeding mechanism 2 includes rotating disks 201. A plurality of rotating disks 201 are evenly distributed. The rotating disks 201 are all rotatably installed at the lower part of the equipment frame 1. Three evenly distributed screw rods 202 are rotatably installed in the middle of the plurality of rotating disks 201. Moving blocks 203 are threadedly installed on the upper parts of the plurality of screw rods 202. Slide rods 204 are fixedly installed in the middle of the plurality of moving blocks 203. Three groups of evenly distributed sliding blocks 206 are slidably clamped on the upper parts of the plurality of rotating disks 201. Both ends of the plurality of slide rods 204 slidably penetrate through the middle of the sliding blocks 206. Clamping blocks 207 are fixedly installed at the tops of the plurality of sliding blocks 206; Rotating disks 212 are fixedly installed at the bottoms of the plurality of rotating disks 201. A plurality of driving grooves 214 are formed in the middle of the plurality of rotating disks 212. Driving disks 209 are provided on one side of the lower parts of the plurality of rotating disks 212. Driving blocks 210 that are matched with the driving grooves 214 are fixedly installed on one side of the tops of the driving disks 209. Driving components are provided at the bottoms of the plurality of driving disks 209.

[0022] By adopting the above technical solution, by rotating the screw rod 202, the two clamping blocks 207 are close to the sliver can 215 to clamp and fix the sliver can 215. Under the mutual cooperation of the driving disk 209, the rotating disk 212 and the rotating disk 201, the sliver can 215 is switched.

[0023] The conveying mechanism 3 includes conveying frames 301. Four conveying frames 301 are symmetrically distributed. The four conveying frames 301 are all fixedly installed on one side of the upper part of the equipment frame 1. Two groups of symmetrically distributed conveying rollers 302 are rotatably installed in the middle of the four conveying frames 301. One-way gears 316 are fixedly installed on one side of the multiple groups of conveying rollers 302, and the one-way gears 316 are meshed with each other. Two symmetrically distributed second rotating shafts 315 are provided on the upper part of the equipment frame 1. Both ends of the two second rotating shafts 315 are fixedly installed in the middle of one side of the one-way gears 316; On the upper side of one side of the equipment frame 1, two symmetrically distributed first rotating shafts 311 are rotatably installed. One end of the first rotating shaft 311 is fixedly installed with a transmission roller 306, and one end of the other first rotating shaft 311 is rotatably installed at one end of the transmission roller 306. One end of the transmission roller 306 is fixedly installed with a second crown gear 305. On the lower side of one side of the second crown gear 305, there is a first crown gear 304. The first crown gear 304 and the second crown gear 305 are meshed and connected with each other. On the upper side of one side of the equipment frame 1, a second motor 303 is fixedly installed. The middle part of the bottom end of the first crown gear 304 is fixedly installed at the driving end of the second motor 303; On one side of the transmission roller 306, a plurality of clamping blocks 307 are fixedly installed. In the middle of one side of the other first rotating shaft 311, a driven block 308 that cooperates with the clamping blocks 307 is slidably clamped. On one side of the driven block 308, a moving plate 310 is rotatably installed. On the upper side of one side of the equipment frame 1, a push rod 309 is fixedly installed. The lower part of one side of the moving plate 310 is fixedly installed at the driving end of the push rod 309. In the middle of one side of each of the two first rotating shafts 311, a fourth crown gear 314 is fixedly installed. In the middle of each of the two second rotating shafts 315, a third crown gear 313 is fixedly installed. And the third crown gear 313 meshes with the corresponding fourth crown gear 314. The two groups of third crown gears 313 and fourth crown gears 314 are mirror-image distributed, and the tooth number ratio of the third crown gear 313 and the fourth crown gear 314 is different.

[0024] By adopting the above technical solution, under the combined drive of the second motor 303 and the push rod 309, the conveying rollers 302 on both sides can convey the sliver, and at the same time, the start and stop of the conveying of the conveying rollers 302 on both sides can be controlled.

[0025] On the upper part of the equipment frame 1, a plurality of uniformly distributed fixing plates 102 are fixedly installed. On one side of each of the plurality of fixing plates 102, a mounting frame 103 is fixedly installed. At the lower part of each of the plurality of mounting frames 103, a guiding tube 104 is rotatably installed. On the lower side of one side of each of the plurality of guiding tubes 104, a feeding port 105 is opened. At the lower part of each of the plurality of guiding tubes 104, a limiting frame 106 is fixedly installed. On the lower side of one side of each of the plurality of limiting frames 106, a sensor 107 is fixedly installed. On one side of the drawing frame 4, a control platform 401 is fixedly installed. Inside the control platform 401, there are a main controller module, a driving device control module, a signal processing module, and a human-computer interaction and communication module.

[0026] By adopting the above technical solution, when the sliver is conveyed, since the sliver is coiled together, when it is conveyed, it will be pulled up one by one, which will drive the limiting frame 106 and the guiding tube 104 to rotate together. Furthermore, under its limitation, the stability of the sliver conveying process is ensured, and the situation that the amplitude is too large when pulling up, resulting in breakage or entanglement with other slivers, is avoided.

[0027] A plurality of guide bar frames 101 that cooperate with the limit frame 106 are fixedly installed on the upper part of the device frame 1.

[0028] By adopting the above technical solution, it is possible to arrange and limit the transportation of multiple strips side by side.

[0029] A plurality of groups of uniformly distributed limiting rods 205 are fixedly installed on the upper parts of the plurality of rotating disks 201, and the lower parts of the plurality of sliding blocks 206 are all slidably clamped on the outer surfaces of the limiting rods 205.

[0030] By adopting the above technical solution, under the limitation of the limiting rod 205, it is ensured that the rotation of the screw 202 drives its two clamping blocks 207 to move along the direction in which the limiting rod 205 is placed.

[0031] Three uniformly distributed strip cylinders 215 are provided at the tops of the plurality of rotating disks 201, one side of each clamping block 207 is in contact with the lower side of one of the strip cylinders 215, and regularly distributed inverted tooth-shaped protrusions are provided at the contact surface between the clamping block 207 and the strip cylinder 215.

[0032] By adopting the above technical solution, the three strip cylinders 215 are respectively filled with the strips to be drawn in parallel. Under the movement of the clamping block 207, the lower part of the strip cylinder 215 can be clamped and fixed to ensure the stability of the strips in the strip cylinder 215 during transportation.

[0033] The driving assembly includes a first motor 208. The first motor 208 is fixedly installed at the lower part of the device frame 1, and the middle parts of the bottoms of the plurality of driving disks 209 are fixedly installed at the driving end of the first motor 208.

[0034] By adopting the above technical solution, the driving disk 209 can be rotated under the drive of the first motor 208.

[0035] A plurality of uniformly distributed limiting grooves 213 are formed on the outer sides of the plurality of rotating disks 212, and limiting blocks 211 that cooperate with the limiting grooves 213 are fixedly installed at the tops of the plurality of driving disks 209.

[0036] By adopting the above technical solution, when the driving block 210 is away from the driving groove 214, the limiting block 211 will be clamped inside the limiting groove 213, so that the rotating disk 212 stops rotating, and thus the rotating disk 212 completes one-side rotation.

[0037] Two symmetrically distributed rotating blocks 312 are fixedly installed on the outer surface of one of the first rotating shafts 311, and both rotating blocks 312 slidably penetrate through the middle part of the driven block 308.

[0038] By adopting the above technical solution, while the driven block 308 can slide on the outer surface of the first rotating shaft 311, under the limit of the rotating block 312, when the driven block 308 rotates, it can drive the first rotating shaft 311 to rotate.

[0039] Working principle: After passing the sliver in the sliver can 215 through the middle of one end of the limit frame 106, it enters the middle of the mounting frame 103 through the feeding port 105 and extends out from the top of the mounting frame 103. Then the sliver is successively passed through the guide bar frame 101 and the conveying roller 302 until it enters the drawing frame equipment 4. The drawing frame equipment 4, the second motor 303 and the electric push rod 309 are controlled to start by the control platform 401. Under the start of the drawing frame equipment 4, the sliver is drawn. Under the drive of the electric push rod 309, the driven block 308 is clamped between a plurality of clamping blocks 307. Driven by the second motor 303, the first crown gear 304 rotates, that is, drives the second crown gear 305 to rotate, so that the transmission roller 306 rotates, that is, drives the two first rotating shafts 311 to rotate, and then drives the two fourth crown gears 314 to rotate, so that the two third crown gears 313 meshed with the fourth crown gears 314 rotate, and then drives the second rotating shaft 315 to rotate. Driven by the rotation of the second rotating shaft 315, the first gear 316 rotates. Since the two first gears 316 are meshed with each other, each two groups of conveying rollers 302 rotate relatively, so as to convey the sliver. The tooth number ratios of the two groups of third crown gears 313 and fourth crown gears 314 are different. The tooth numbers of the third crown gear 313 and the fourth crown gear 314 on the side close to the drawing frame equipment 4 are 0.95 times that of the other side. As a result, there is a speed difference between the conveying rollers 302 on both sides, so that the rotating speed of the conveying roller 302 on the side far from the drawing frame equipment 4 is faster during the conveying of the sliver, while the rotating speed of the side close to it is slower. Therefore, when the sliver is conveyed, there will be some sliver between the conveying rollers 302. When the sliver in the creel 215 is used up, the sliver will then disengage from the middle of the limit frame 106, and the sensor 107 senses that the end of the sliver has disengaged from the limit frame 106, and thus will feedback to the control platform 401. Under the analysis and control of the control platform 401, the first motor 208 at the lower part of the creel 215 is driven, and by controlling the operation of the electric push rod 309, the driving disc 209 is driven to rotate under the drive of the first motor 208, that is, the driving block 210 is driven to rotate. When the driving block 210 is inserted into the driving groove 214 during rotation, the rotating disc 212 is driven to rotate. After the driving block 210 moves away from the driving groove 214, its limit block 211 will be clamped inside the limit groove 213, thereby causing the rotating disc 212 to stop rotating. At this time, the first motor 208 stops driving. Under the intermittent rotation of the rotating disc 212, the rotating disc 201 with three creels 215 placed on the upper part can be driven to rotate, that is, the used-up creel 215 is moved to one side, and the creel 215 filled with sliver on the other side will move to the lower part of the limit frame 106. After the staff passes the existing sliver through the sensor 107 and the middle of the limit frame 106, the staff uses a bamboo stick to twist and connect, thus completing the replacement and connection work; Driven by the electric push rod 309, the moving plate 310 is driven to move away from the side of the transmission roller 306, so that the driven block 308 and the clamping block 307 are no longer in contact, and thus the first rotating shaft 311 on the side where the rotating block 312 is installed no longer rotates, and thus the plurality of conveying rollers 302 no longer rotate. However, the conveying rollers 302 close to the drawing equipment 4 still rotate, and convey the sliver left due to the speed difference between the conveying rollers 302 during the previous work. And the end of the sliver on one side of the limit frame 106 will not move, thus ensuring that time is left for the staff to connect, and further ensuring that the replacement of the creel 215 and the connection work of the sliver can be carried out smoothly without stopping the equipment; When replacing the creel 215, when the rotating disc 201 is in a static state, by rotating the screw rod 202, the moving block 203 and the sliding rod 204 move away from the creel 215, thereby driving the sliding block 206 and the clamping block 207 away from the creel 215, and thus the creel 215 can be removed from the upper part of the rotating disc 201. The creel 215 filled with sliver is newly placed on the rotating disc 201, and by rotating the screw rod 202 in the reverse direction, the two clamping blocks 207 are close to the lower part of the creel 215, thereby clamping and fixing the creel 215.
