Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a variable speed combing device for cotton yarn combing machines. Background Technology

[0002] A combing machine is a machine used in the spinning process to perform the combing process. Its main functions are to remove shorter fibers, remove knots (neps, wool particles, grass clippings, cocoon skins, etc.) from the fibers, and further straighten and parallel the fibers, ultimately producing combed slivers with a relatively uniform thickness.

[0003] However, in existing technologies, most combing machines adopt a single-direction reciprocating oscillation design. The comb teeth can only scrape the surface of the cotton yarn in one direction along a fixed trajectory. Although this single-direction combing mode can clean the coarse impurities on the surface of the cotton yarn, it is difficult to effectively clean the fine impurities in the gaps and folds formed by the interlacing of fibers. This results in insufficient deep cleaning of the cotton yarn after combing, which can easily lead to defects in subsequent processes and ultimately affect the overall quality of the cotton yarn. In addition, the oscillation frequency is mostly set to a fixed value, lacking the ability to flexibly adjust and adapt to various cotton yarns. This increases the investment cost of the equipment and also requires the machine to be stopped and the internal mechanical structure replaced when changing cotton yarns, which greatly reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a variable speed combing device for cotton yarn combing machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a variable speed combing device for a cotton yarn combing machine, comprising a main body, an internal swing mechanism, and a variable speed mechanism.

[0019] 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. Example

[0020] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a variable speed combing device for a cotton yarn combing machine, including a main body 1, an internal swing mechanism 2, and an external speed-changing mechanism 3. The swing mechanism 2 includes a shaft 21, an upper combing plate 22 on the shaft 21, comb teeth 23 at the bottom of the upper combing plate 22, a counterweight rod 24 at the top of the upper combing plate 22, a counterweight block 25 on the counterweight rod 24, double clamps 26 above and below the counterweight block 25, and a ball bearing slider 27 inserted through the top of the upper combing plate 22. A guide rail 28 is provided on the side of the ball slider 27 away from the shaft 21. A fixing plate 29 is provided on the side of the guide rail 28 away from the ball slider 27. A limiting rod 210 is provided below the shaft 21. A counterweight rod 24 is welded to the top of the upper comb plate 22. Two double clamps 26 limit the counterweight block 25. The ball slider 27 is movably engaged with the guide rail 28. The guide rail 28 is fixedly connected to the fixing plate 29 with bolts. The fixing plate 29 is fixedly connected to the main body mechanism 1 with bolts. The shaft 21 is movably engaged with the main body mechanism 1. The shaft 21 passes through the upper comb plate 22 and the two ball sliders 27 and limits their movement.

[0021] In this embodiment, after the device is started, due to the relatively stable vibration during the operation of the device, the two ball bearing sliders 27 installed on the guide rail 28 can drive the upper comb plate 22 on the shaft 21 to move back and forth. During this process, the upper comb plate 22 drives the bottom comb teeth 23 to swing. Through the swinging action, the comb teeth 23 that are combing the cotton yarn can more efficiently remove impurities from the cotton yarn. The precise cooperation between the ball bearing sliders 27 and the guide rail 28 ensures that the swing trajectory of the upper comb plate 22 and the comb teeth 23 is always consistent, avoiding missed combing and repeated combing caused by deviation, so that each area of ​​the cotton yarn can be combed evenly, reducing secondary rework and improving the production efficiency of the equipment. When the device generates stable vibration during operation, the weight of the counterweight 25 installed on the counterweight rod 24 forms an inertial torque. When the shaft 21 drives the upper comb plate 22 to swing forward, the center of gravity of the counterweight 25 will lag behind the swing direction, forming a reverse restraining force. The reverse restraining force can offset the additional impact force brought by the vibration. When the upper comb plate 22 swings backward, the weight of the counterweight 25 will be converted into an auxiliary pulling force to compensate for the power attenuation caused by the vibration. The cooperation of the two forces makes the back-and-forth swing of the upper comb plate 22 more stable. The limiting rod 210 installed below the shaft 21 can rigidly limit the back-and-forth swing of the upper comb plate 22, so that its swing amplitude is controlled within the preset safe range. The double clamps 26 installed above and below the counterweight 25 can realize the up-and-down adjustment of the counterweight 25. The up-and-down adjustment of the counterweight 25 can make the swing of the upper comb plate 22 adapt to different cotton yarn combing needs. Example

[0022] like Figure 1 - Figure 4 As shown, the transmission mechanism 3 includes a transmission rod 31, with hydraulic cylinders 32 located above and below the transmission rod 31. A fixed seat 33 is located on the side of the hydraulic cylinder 32 away from the transmission rod 31. A Y-shaped hydraulic pipe 34 is connected to one side of each hydraulic cylinder 32. A throttle valve 35 is located at the top of the Y-shaped hydraulic pipe 34, and a hydraulic pipe 36 is located at the top of the throttle valve 35. A hydraulic rod 37 is located on the side of the hydraulic pipe 36 away from the throttle valve 35. The transmission rod 31 is welded and fixedly connected to the main body mechanism 1. The Y-shaped hydraulic pipe 34 is threaded and sealed to the two hydraulic cylinders 32. The throttle valve 35 is threaded and sealed to the Y-shaped hydraulic pipe 34 and the hydraulic pipe 36. The hydraulic pipe 36 is threaded and sealed to the hydraulic rod 37. The hydraulic rod 37 is welded and fixedly connected to the main body mechanism 1. The fixed seat 33 is bolted to the main body mechanism 1. The end of the hydraulic cylinder 32 away from the fixed seat 33 is glued and fixed to the transmission rod 31.

[0023] In this embodiment, the transmission rod 31, which is welded and fixed to the side of the main body 1, can receive vibrations from different directions of the device and convert the vibrations into hydraulic auxiliary power. The structure in which the transmission rod 31 and the hydraulic cylinder 32 are glued and fixed together can transmit the small displacement generated by the vibration to the hydraulic cylinder 32. The hydraulic cylinder 32 pushes the internal piston synchronously due to the displacement of the transmission rod 31, so that the force of the hydraulic oil is transmitted to the hydraulic rod 37 through the Y-shaped hydraulic pipe 34 and the hydraulic pipe 36. Since the hydraulic rod 37 is rigidly connected to the ball slider 27, the piston of the hydraulic rod 37 will directly push the ball slider 27 to slide along the guide rail 28, so that the ball slider 27 drives the upper comb plate 22 to reciprocate. The flow rate and pressure of the hydraulic oil can be adjusted by the throttle valve 35 installed between the Y-shaped hydraulic pipe 34 and the hydraulic pipe 36. When low-speed fine combing is required, the flow rate is reduced by adjusting the throttle valve 35, which slows down the left and right swinging speed of the comb teeth 23 and makes the swinging force gentler, avoiding excessive force that may break the fine fibers. The low-speed swinging can carefully peel off the attached fine impurities. When high-speed and high-efficiency combing is required, the flow rate is increased by adjusting the throttle valve 35, which speeds up the left and right swinging speed of the comb teeth 23 and increases the swinging force, which can quickly and efficiently peel off the tangled coarse fiber impurities.

[0024] like Figure 1 - Figure 4 As shown: During operation, the vibration generated by the entire device is transmitted through the main body mechanism 1 to the transmission rod 31 welded and fixed to its side. The transmission rod 31 reciprocates due to the vibration, which in turn pushes the piston inside the hydraulic cylinder 32, which is bonded and fixed to the transmission rod 31. The piston movement drives the hydraulic oil, which is transmitted through the Y-shaped hydraulic pipe 34, the throttle valve 35, and the hydraulic pipe 36 to the hydraulic rod 37. This pushes the piston of the hydraulic rod 37 to drive the ball slider 27. The ball slider 27 slides stably along the guide rail 28, causing the ball slider 27 to drive the upper comb plate 22 to reciprocate. The upper comb plate 22 synchronously drives the bottom comb teeth 23 to swing left and right, realizing the... During the combing process, impurities are removed from the cotton yarn. At the same time, the counterweight 25 installed on the counterweight rod 24 generates inertia due to the vibration of the device. The center of gravity of the counterweight 25 shifts with the vibration. Through the rigid connection between the counterweight rod 24 and the upper comb plate 22, the comb teeth 23 are driven to swing back and forth. The two swinging forces work together. The force of the comb teeth 23 swinging left and right is responsible for laterally removing impurities from the surface of the cotton yarn, while the back and forth swinging covers the fine fibers at the edges and gaps of the cotton yarn. Through the cross combing trajectory of the two forces, impurities are avoided in dead corners. At the same time, the contact between the comb teeth 23 and the cotton yarn is made closer, resulting in a more uniform arrangement of cotton yarn and fewer impurities after combing. When low-speed fine combing is required, the flow rate is reduced by adjusting the throttle valve 35, thereby reducing the flow rate and pressure of the hydraulic oil. At this time, the transmission speed of the hydraulic oil between the Y-shaped hydraulic pipe 34 and the hydraulic pipe 36 is slowed down, and the force pushing the piston of the hydraulic rod 37 is weakened. This results in a decrease in the frequency of the ball block slider 27 sliding along the guide rail 28, and a slower reciprocating rhythm of the upper comb plate 22. Consequently, the left and right swing speed of the comb teeth 23 is slowed down. At the same time, the upper and lower double clamps 26 are loosened to adjust the counterweight block 25. After the counterweight block 25 is moved upward along the counterweight rod 24, the double clamps 26 are tightened to fix it. After the counterweight block 25 moves upward, the lever arm between it and the upper comb plate 22 becomes longer, and the center of gravity shift caused by vibration inertia is reduced. The forward and backward swing thrust transmitted to the upper comb plate 22 through the counterweight rod 24 is weakened. The slow swing of the two forces avoids excessive force from hooking and breaking fine fibers, and increases the contact time with the cotton yarn, enabling more delicate removal of small impurities attached to the cotton yarn. When high-speed and efficient combing is required, the flow rate is increased by adjusting the throttle valve 35, thereby increasing the flow and pressure of the hydraulic oil. At this time, the transmission speed of the hydraulic oil between the Y-shaped hydraulic pipe 34 and the hydraulic pipe 36 is accelerated, which strengthens the force pushing the piston of the hydraulic rod 37, causing the ball slider 27 to slide along the guide rail 28 at a higher frequency. The reciprocating motion rhythm of the upper comb plate 22 is accelerated, which in turn increases the left and right swing speed of the comb teeth 23. At the same time, the upper and lower double clamps 26 are loosened to adjust the counterweight block 25. After the counterweight block 25 is moved downward along the counterweight rod 24, the double clamps 26 are tightened to fix it. After the counterweight block 25 moves downward, the lever arm between it and the upper comb plate 22 is shortened, and the center of gravity shift caused by vibration inertia is increased. The forward and backward swing thrust transmitted to the upper comb plate 22 through the counterweight rod 24 is enhanced. The high-frequency coordinated swing of the two forces shortens the combing time of a single cotton yarn through high-speed motion. With the help of the increased swing amplitude of the comb teeth 23, large impurities mixed in the coarse and stiff cotton yarn are quickly removed, ultimately achieving rapid cleaning of large batches of cotton yarn.
