Description

Technical Field

[0001] This utility model relates to the field of cotton spinning production technology, specifically to a drafting device for cotton spinning production. Background Technology

[0002] In cotton spinning production, the drafting device is used to separate and stretch fibers or yarns from cotton to improve fiber uniformity, density, and the strength of the final yarn. This type of device is typically one of the key pieces of equipment in a spinning production line, usually used to comb and stretch fibers to form a uniform fiber strip or yarn.

[0003] In traditional equipment, without a conveyor belt or similar device, the delivery of raw materials may rely on manual or other unstable methods, which can easily lead to uneven feeding, thereby affecting the uniformity of drafting and yarn quality.

[0004] Secondly, if the drive rollers cannot be disassembled or replaced, the production line may only be able to handle a limited number of types of raw materials, making it unable to meet different spinning needs and reducing production flexibility.

[0005] Finally, if only one motor drives the drafting roller, it may not be able to provide a uniform and stable stretching effect at different stages, which may easily lead to uneven tension during the drafting process, causing fiber breakage or unevenness. Summary of the Invention

[0020] 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.

[0021] Example 1: Please see Figures 1-5A drafting device for cotton spinning production includes a main body 1, a mating mechanism, an installation mechanism, and a driving mechanism. The mating mechanism includes a first motor 2 and a transmission roller 3. The first motor 2 is fixedly installed on one side of the main body 1. The transmission roller 3 is fixedly connected to the first motor 2 and rotatably connected to the main body 1. A transmission belt 4 is installed on the transmission roller 3 and is mated to the transmission roller 3. A driven roller 5 is installed on the main body 1 and is arranged in a linear array on the main body 1. The installation mechanism includes an installation rod 6 and a driving roller 7. The installation rod 6 is slidably connected to the driving roller 7. The driving roller 7 is installed on the main body 1 and rotatably connected to the main body 1. A mating block 8 and a threaded sleeve 9 are installed at one end of the installation rod 6. The mating block 8 is mated to the installation rod 6, and the threaded sleeve 9 is mated to the installation rod 6. A positioning element 10 is installed at one end of the installation rod 6. The positioning element 10 is magnetically connected to the installation rod 6 and mated to the threaded sleeve 9.

[0022] In this embodiment, the cooperating mechanism includes a first motor 2 and a transmission roller 3. In use, the first motor 2 can be directly driven, and the first motor 2 rotates on the main body 1, so that the transmission roller 3 can rotate inside the main body 1. The transmission belt 4 rotates as a result. When the raw material comes into contact with the transmission belt 4, the raw material is directly transmitted between the vertical plates 13 of the main body 1 and, under the action of the driven roller 5, the raw material can be transmitted to the driving mechanism to complete the stretching.

[0023] In this embodiment, the mounting mechanism includes a mounting rod 6 and a drive roller 7. In use, the drive roller 7 can be mounted onto the main body 1, and the mounting rod 6 can be mounted onto the drive roller 7. The sliding groove 16 on the mounting rod 6 engages with the roller 15 on the main body 1, and the limiting block 18 on the mounting rod 6 engages with the limiting groove 17 on the drive roller 7. After one end of the mounting rod 6 passes through the main body 1, a mating block 8 can be mounted onto one end of the mounting rod 6. Subsequently, a threaded sleeve 9 can be mounted onto the main body 1, such that the threaded sleeve 9 engages with the threaded rod on the mounting rod 6. The 19 parts are connected together, and then the positioning part 10 is added so that the magnetic suction rod 21 on the positioning part 10 is connected to the fitting hole 22. The positioning part 10 is connected to the positioning hole 20 on the threaded sleeve 9 so that the position of the threaded sleeve 9 can be stabilized. The second motor 11 installed at the bottom of the main body 1 can rotate the active block 23 stably under the action of the mounting plate 14. The transmission belt 12 installed in the transmission groove 24 enables the mating block 8 to drive the drive roller 7 to rotate. Different second motors 11 rotate at different speeds, so that the raw material is perfectly drawn.

[0024] Example 2: In summary, during use, the device can first be assembled. The drive roller 7 can be installed onto the main body 1, and the mounting rod 6 can be installed onto the drive roller 7. The sliding groove 16 on the mounting rod 6 is connected to the roller 15 on the main body 1, and the limiting block 18 on the mounting rod 6 is connected to the limiting groove 17 on the drive roller 7. After one end of the mounting rod 6 passes through the main body 1, the mating block 8 can be installed onto one end of the mounting rod 6. Then, the threaded sleeve 9 can be installed onto the main body 1, so that the threaded sleeve 9 is connected to the screw 19 on the mounting rod 6. Then, the positioning component 10 is added, so that the magnetic suction rod 21 on the positioning component 10 is connected to the fitting hole 22, and the positioning component 10 is connected to the positioning hole 20 on the threaded sleeve 9, so that the position of the threaded sleeve 9 is determined. The second motor 11 installed at the bottom of the main body 1 can rotate stably under the action of the mounting plate 14. The drive block 23 can rotate stably. The transmission belt 12 installed in the transmission groove 24 enables the mating block 8 to drive the drive roller 7 to rotate. Different second motors 11 rotate at different speeds, so that the raw material is perfectly drawn. When the raw material needs to be processed and drawn, the first motor 2 can be directly driven. The first motor 2 rotates on the main body 1, and the transmission roller 3 can rotate inside the main body 1. The transmission belt 4 rotates as a result. When the raw material comes into contact with the transmission belt 4, the raw material is directly transferred to the vertical plate 13 of the main body 1 and, under the action of the driven roller 5, the raw material can be transferred to the drive mechanism to complete the drawing.
