Description

Technical Field

[0001] This utility model relates to the technical field of cotton yarn processing equipment, specifically a carding machine for cotton yarn processing. Background Technology

[0002] A carding machine opens, combs, and removes impurities from cotton laps or oily cotton layers supplied by cotton boxes from previous processes. This transforms the curled, lumpy cotton loops into relatively straight single fibers. During this process, it removes broken seeds, impurities, and short fibers left over from the cleaning process. The resulting cotton is then bundled into slivers of a specific size and stored in cotton cans for use in the drawing process.

[0003] Traditional carding machines typically have a fixed take-up roller position. As the cotton lap diameter increases, the distance between the take-up roller and the doffer cannot be dynamically adjusted, leading to several shortcomings in practical use. For example, as the cotton lap diameter increases, the transport path of the cotton layer from the doffer to the take-up roller becomes longer. This increases the amount of sag due to gravity, causing the cotton layer tension to gradually decrease. This results in a loose outer layer and a tight inner layer, severely affecting the quality of the cotton lap. Furthermore, different lap sizes require different distances between the take-up roller and the doffer. A fixed position is difficult to adapt to the needs of multi-variety production, and manual disassembly and adjustment are required during model changes, which is time-consuming and labor-intensive, significantly reducing production efficiency. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the position of the take-up roller of a traditional carding machine is usually fixed. As the diameter of the cotton roll gradually increases, it is impossible to dynamically adjust the distance with the doffer, which has many shortcomings in actual use.

[0005] To solve the above-mentioned technical problems, this application provides a carding machine for cotton yarn processing, including a machine body. A movable frame is slidably connected to one end of the machine body. Slide rails are provided on both sides of the middle of the middle of one end of the machine body. A lead screw is rotatably installed in the middle of one of the slide rails. A slider is fixedly installed on one side of the middle of the lower end of the movable frame. A pulley is fixedly installed on the other side of the middle of the lower end of the movable frame. Moving wheels are fixedly installed at the two corners of the lower end of the movable frame. A cylinder is fixedly installed in the middle of the upper end of the movable frame. A bracket is fixedly installed at the output end of the cylinder. Pressure plates are fixedly installed on both sides of the middle of the upper end of the bracket by screws. A rotating groove is formed between the middle of the bracket and the pressure plate. A take-up roller is rotatably installed in the middle of the rotating groove.

[0006] In some embodiments, a feed pipe is fixedly connected to the upper part of the other end of the machine body, and a discharge port is opened in the middle of one end of the machine body, with two slide rails located at the end of the machine body where the discharge port is opened.

[0007] In some embodiments, an inlet roller is rotatably mounted in the middle of the feed pipe, and a needle roller, a coarse sawtooth roller, and a fine sawtooth roller are rotatably mounted sequentially at one end of the middle of the machine body.

[0008] In some embodiments, a movable cover is rotatably mounted on the middle of the fuselage, a cylinder is provided above the middle of the fuselage, and a doffer is rotatably mounted at the other end of the middle of the fuselage.

[0009] In some embodiments, one end of the take-up roller is provided with a cross slot, and one side of the upper end of the movable frame is provided with a slide groove. The end of the take-up roller with the cross slot is located near the side of the movable frame with the slide groove.

[0010] In some embodiments, the slider is slidably engaged with the middle of one of the slide rails, the slide rails and the lead screw are threadedly connected, and the pulley is slidably engaged with the middle of another slide rail.

[0011] In some embodiments, one end of one of the slide rails is provided with a mounting groove, a motor is fixedly mounted in the middle of the mounting groove, the output end of the motor is fixedly connected to one end of the lead screw, and a filter screen is snapped into one side of the mounting groove.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. In use, this utility model enables precise dynamic positioning of the take-up roller, thereby ensuring winding quality. Through the lateral movement of the motor-driven lead screw and the vertical lifting and lowering of the cylinder-driven support, the take-up roller can be adjusted in real time within the lateral and longitudinal spaces. When the cotton roll diameter increases, the cylinder synchronously raises the height of the take-up roller to maintain a constant process distance from the doffer. If the cotton layer output deviates, the lead screw drive laterally fine-tunes the position of the movable frame to ensure that the cotton layer is always aligned with the center of the take-up roller, thus mechanically guaranteeing tension stability and cotton roll uniformity during the winding process.

[0014] 2. When in use, the combination structure of the movable frame and the slide rail supports the overall lateral movement. Combined with the vertical adjustment function of the bracket and the take-up roller, the equipment can be maintained without disassembling complex parts. For example, when cleaning the take-up roller, the working area can be quickly exposed through the slide rail for quick cleaning. When the cotton roll needs to be replaced, the screws used to fix the pressure plate can be removed to remove the restriction on the take-up roller, thus enabling replacement.

[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 refer to Figures 1-4 This utility model provides a technical solution: a carding machine for cotton yarn processing, including a machine body 1, a movable frame 25 slidably connected to one end of the machine body 1, slide rails 2 on both sides of the middle of one end of the machine body 1, a lead screw 24 rotatably mounted in the middle of one of the slide rails 2, a slider 26 fixedly mounted on one side of the middle of the lower end of the movable frame 25, a pulley 27 fixedly mounted on the other side of the middle of the lower end of the movable frame 25, and movable wheels 28 fixedly mounted at the two corners of the lower end of the movable frame 25, a cylinder 30 fixedly mounted in the middle of the upper end of the movable frame 25, a bracket 31 fixedly mounted at the output end of the cylinder 30, and pressure plates 32 fixedly mounted on both sides of the middle of the upper end of the bracket 31 by screws, the bracket 31 and the pressure plates 32... A rotating groove 33 is formed in the middle, and a take-up roller 34 is rotatably installed in the middle of the rotating groove 33. A cross slot 35 is opened at one end of the take-up roller 34. A sliding groove 29 is opened on one side of the upper end of the movable frame 25. The end of the take-up roller 34 with the cross slot 35 is located near the side of the movable frame 25 with the sliding groove 29. A slider 26 is slidably engaged in the middle of one of the slide rails 2. The slide rail 2 and the lead screw 24 are threadedly connected. A pulley 27 is slidably engaged in the middle of another slide rail 2. A mounting groove 21 is opened at one end of one of the slide rails 2. A motor 22 is fixedly installed in the middle of the mounting groove 21. The output end of the motor 22 is fixedly connected to one end of the lead screw 24. A filter screen 23 is engaged on one side of the mounting groove 21.

[0022] In this embodiment, dynamic adjustment of the take-up roller 34 in the up-down and left-right directions can be achieved. The movable frame 25 can move as a whole along the slide rail 2. The user can drive the lead screw 24 to rotate through the motor 22. Due to the threaded transmission between the lead screw 24 and the slider 26, the rotation of the lead screw 24 can drive the movable frame 25 to move laterally along the slide rail 2. The other end of the movable frame 25 is provided with a pulley 27. The pulley 27 and the slide rail 2 cooperate with each other. With the moving wheel 28 at the bottom of the movable frame 25, the lateral movement resistance of the movable frame 25 can be greatly reduced. The cylinder 30 can drive the bracket 31 to move up and down, thereby adjusting the upper take-up roller 34. The vertical distance between the take-up roller 34 and the doffer 19 can be dynamically adjusted according to the change of the roll diameter. By dynamically adjusting the position of the take-up roller 34, the quality of cotton roll forming can be improved. The external driving device is connected to the take-up roller 34 through a cross-shaped insert that matches the cross slot 35 at one end of the take-up roller 34 to provide power for it. The slide 29 can provide the external driving device with activity space as the take-up roller 34 moves up and down.

[0023] Example 2: As Figures 1-2 As shown, a feed pipe 11 is fixedly connected to the upper part of the other end of the machine body 1. A discharge port 12 is opened in the middle of one end of the machine body 1. Two slide rails 2 are located at the end of the machine body 1 where the discharge port 12 is opened. An inlet roller 13 is rotatably installed in the middle of the feed pipe 11. A needle roller 14, a coarse sawtooth roller 15 and a fine sawtooth roller 16 are rotatably installed in sequence in one end of the middle of the machine body 1. A movable cover plate 17 is rotatably installed in the middle of the machine body 1. A cylinder 18 is provided above the middle of the machine body 1. A doffer 19 is rotatably installed at the other end of the middle of the machine body 1.

[0024] In this embodiment, the guide roller 13 in the feed pipe 11 can uniformly introduce the fiber raw material. The needle roller 14 first loosens the fiber bundle to reduce the number of knots. The coarse sawtooth roller 15 can further comb the fiber, thereby increasing the average fiber length and reducing the short fiber content. The fine sawtooth roller 16 can make the separated single fibers meet the requirements of combed yarn production through the dense tooth combing of the tooth tip radius. The movable cover plate 17 and the cylinder 18 form an elastic grip combing area, generating relative twisting, which increases the fiber straightness and reduces the content of hooked fibers. The doffer 19 can realize the efficient transfer of fibers. The processed yarn will be discharged through the discharge port 12 and then wound up by the subsequent take-up roller 34.

[0025] like Figures 1-4As shown, during use, the cotton yarn to be processed enters the machine body 1 from the feed pipe 11 under the drive of the inlet roller 13. The cotton yarn entering the machine body 1 passes sequentially through the needle roller 14, the coarse sawtooth roller 15, and the fine sawtooth roller 16. Each roller, through the rotation of the surface needle cloth or sawtooth, tears and loosens the cotton yarn, causing the fiber bundles to separate. The cylinder 18 and the movable cover plate 17 in the middle of the machine body 1 form an elastic gripping combing area, which generates relative twisting under high-speed rotation, which can drive the fibers to spread further. The doffer 19 can realize the efficient transfer of fibers. The processed yarn is discharged through the outlet 12 and then wound up by the subsequent take-up roller 34. The user can dynamically adjust the positional relationship between the take-up roller 34 and the doffer 19, which can improve the uniformity of cotton roll density and edge neatness, and reduce the breakage rate in subsequent processes. During adjustment, motor 22 drives lead screw 24 to rotate. Through the threaded transmission between lead screw 24 and slider 26, movable frame 25 moves laterally along slide rail 2. Pulley 27 rolls on another slide rail 2. Moving wheel 28 supports movable frame 25. The two work together to effectively reduce frictional resistance. Cylinder 30 pushes bracket 31 up and down along the vertical guide rail of movable frame 25 to directly adjust the height of take-up roller 34. Take-up roller 34 is connected to external drive equipment through cross slot 35. Slide groove 29 provides space compensation for vertical movement. When the roll diameter increases, cylinder 30 simultaneously lifts take-up roller 34 to maintain matching with the linear speed of doffer 19 and avoid sudden changes in cotton layer tension. When the cotton layer shifts, motor 22 finely adjusts the position of movable frame 25 to ensure that the cotton layer is always aligned with the center of take-up roller 34, which has extremely high practicality.
