Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a yarn-forming machine with adjustable drafting force. Background Art

[0002] Textile machinery is a general term for various mechanical equipment that processes natural fibers or chemical fibers into the required textiles. In a broad sense, textile machinery also includes chemical machinery for producing chemical fibers. Textile machinery is the means of production and material basis of the textile industry. Its technical level, quality and manufacturing cost are directly related to the development of the textile industry. The spinning machine is a commonly used textile machine in textile equipment. The spinning machine is mainly used to make the fabric have a certain strength and fastness. The yarn must have a certain strength. Yarn strength is an important indicator for evaluating yarn quality. However, the existing spinning machine has a fixed drafting force on the fiber, which is inconvenient to adjust the drafting force of the spinning machine according to the thickness of the fiber. Therefore, we have introduced a spinning machine with adjustable drafting force.

[0003] The existing patent (publication number: CN209162287U) discloses a cotton fiber strip dry yarn-forming mechanism, which belongs to the field of dry yarn-forming mechanisms, including a bracket, a fiber tube, a roller assembly, a baffle, an air-drying assembly, a pressure roller assembly, a driving assembly, and a heat dissipation assembly; the roller assembly includes an active round roller and a driven round roller; the driving assembly includes a motor, a second sprocket, and a third sprocket; the air-drying assembly includes a first air intake shell and a second air intake shell; the heat dissipation assembly includes a sealed heat dissipation cover, a fan, a first heat sink, and a second heat sink. The cotton fiber strip dry yarn-forming mechanism of the utility model, the combination of the roller assembly and the pressure roller assembly improves the tension of the fiber strip, avoids winding and breaking, and the air-drying assembly quickly blows away the water vapor to prevent the later storage of the fiber strip from being too wet and mildewed; the first heat sink and the second heat sink improve the heat dissipation effect; thereby avoiding cotton wool from entering the motor to cause blockage, improving the heat dissipation function of the motor, ensuring the normal use of the motor, and ensuring production efficiency and production stability. The existing technology has the following problems: 1. The existing spinning machine has a fixed drafting force on the fiber, which makes it inconvenient to adjust the drafting force of the spinning machine according to the thickness of the fiber; 2. The existing spinning machine will generate a large amount of flying catkins floating in the air when working, and most of the existing spinning machines do not have the function of cleaning the flying catkins separately. Most of them use external cleaning equipment, which increases the production cost. Utility Model Content

[0027] In this embodiment, Figure 2, Figure 3 and Figure 4 As shown, the dust suction assembly 4 includes two groups of dust suction boxes 401 fixedly connected to the bottom of the inner wall of the dust cover 1, and the middle parts of the two groups of dust suction boxes 401 are fixedly connected with dust suction pumps 402.

[0028] The use method and advantages of the utility model: When the spinning machine with the function of preventing fiber winding is used, the working process is as follows:

Then the motor 201 is started to drive the transmission component 2 to transmit. At this time, the winding roller 302 and the conveying roller 301 will rotate synchronously under the action of the transmission component 2 to ensure the stability of the transmission and keep the tension of the fiber consistent during the yarn-making process. When the tension of the fiber needs to be changed, the cylinder 309 is started to extend and retract to drive the lifting plate 306 to rise and fall. The lifting plate 306 will drive the squeezing roller 307 at the bottom to rise and fall synchronously. Because the squeezing roller 307 and the guide roller 303 are staggered, when the squeezing roller 307 moves downward, the yarn between the guide roller 303 and the rubbing roller 304 will be squeezed downward, thereby The tension of the yarn is increased to achieve the purpose of changing the yarn drafting force, so as to adjust the drafting force according to fibers of different thicknesses and improve the adaptability of the spinning machine. While the transmission component 2 is operating, it will drive the cam 408 to rotate through the rotating shaft. When the cam 408 rotates, it will drive the cross bars 405 on both sides of the circular ring 406 to perform reciprocating linear motion through the movement of the connecting column 407 in the circular ring 406. The dust box 401 is fixedly installed on the cross bar 405, so it can drive the dust collection component 4 to reciprocate at the inner bottom of the dust cover 1 to collect the flying catkins generated above, thereby increasing the collection range and achieving better collection effect. No external cleaning equipment is required, and only the driving device on the spinning machine body is relied on to simultaneously achieve spinning and dust collection, thereby reducing production costs.
