Description

Technical Field

[0001] The utility model relates to the technical field of cotton carding machines, in particular to a cotton carding machine. Background Art

[0002] Carding machines are essential textile machinery used for processing cotton and chemical fibers. Carding plays a crucial role in the spinning process. The carding process typically begins with a blowroom and draw frame, followed by a draw frame (in the carding process) or a lap lap. Currently, many carding machines receive laps from upstream processes during operation. These laps are typically wound on paper rolls, which facilitate storage and transport while also providing support during the carding process.

[0003] However, in practice, placing the cotton laps at the carding machine's feed port is often a manual process. This requires a high level of physical strength, and prolonged work can lead to excessive exhaustion. As physical strength gradually declines, the worker's efficiency in placing the laps also decreases. This not only affects overall production efficiency but also increases labor intensity. Therefore, we propose a new carding machine. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present invention provides a carding machine that solves the problem that in actual operation, the step of placing the cotton rolls at the feeding port of the carding machine often requires workers to manually complete this task. This long-term work can easily lead to excessive physical exhaustion. This not only affects the overall production efficiency, but also may increase the labor intensity of the workers.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a carding machine, comprising a carding machine body, wherein a cotton roll positioning mechanism is provided on the left side of the carding machine body.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0018] 1. The present invention realizes the automatic conveying of cotton rolls by providing a cotton roll conveyor belt and a cotton roll guide mechanism. The operator only needs to place the cotton rolls neatly on the cotton roll conveyor belt, and the conveyor belt can automatically transport the cotton rolls from the storage or supply area to the working area of ​​the carding machine, which greatly reduces the physical burden of manually carrying the cotton rolls and improves the stability and efficiency of cotton roll transportation. At the same time, when the cotton rolls are used up, by starting the double-axis motor to rotate in the opposite direction, the shaft will automatically detach from the paper roll, and the paper roll will naturally fall along the paper roll exclusion groove provided between the guide platform and the positioning rod. Then the new cotton roll will automatically roll to the designated position without manual intervention, thus realizing the automatic replacement of cotton rolls. This design not only further improves production efficiency, but also significantly reduces the labor intensity of operators, effectively solving the problems of high physical exertion and low work efficiency caused by relying on manual placement of cotton rolls mentioned in the background technology.

[0019] 2. The utility model realizes precise horizontal and vertical positioning of the cotton roll by setting up a cotton roll positioning mechanism. The cotton roll positioning mechanism includes components such as a bracket, an arc block, a positioning rod, a gantry, a dual-axis motor, a screw, a ball screw, a linkage rod and a shaft rod. When the cotton roll rolls between the arc block and the positioning rod, the combined structure of the two effectively limits the horizontal movement of the cotton roll. Subsequently, by starting the dual-axis motor to drive the screw to rotate, the ball screw moves along the screw, and then drives the linkage rod and the shaft rod to move inward, inserting the shaft rod into both ends of the paper tube inside the cotton roll, thereby realizing the vertical positioning of the cotton roll. This design enhances the stability of the cotton roll during the carding process and improves the carding quality and efficiency of the carding machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The utility model provides a technical solution:

[0031] See also Figures 1 to 4 The carding machine comprises a carding machine body 1 , and a lap positioning mechanism 2 is provided on the left side of the carding machine body 1 .

[0032] The cotton roll positioning mechanism 2 includes a bracket 21, an arc block 22 is fixedly installed on the inner side of the bracket 21, a positioning rod 23 is fixedly installed on the inner side of the arc block 22, a gantry 24 is fixedly installed on the top of the bracket 21, a dual-axis motor 25 is fixedly installed at the center of the top of the gantry 24, a screw 26 is fixedly installed on the output end of the dual-axis motor 25, the outer side of the screw 26 is threadedly connected to a ball screw block 27, a linkage rod 28 is fixedly installed on the bottom of the ball screw block 27, and an axle rod 29 is fixedly installed on the inner side of the linkage rod 28, and the end of the screw 26 away from the dual-axis motor 25 is rotatably connected to a right-angle frame 210. Through the coordinated action of the bracket 21, the arc block 22, the positioning rod 23, the gantry 24, the dual-axis motor 25, the screw 26, the ball screw block 27, the linkage rod 28 and the axle rod 29, the automatic positioning and limiting of the cotton roll in the combing process are realized, ensuring the stable transportation of the cotton roll and the efficient combing operation.

[0033] Furthermore, the bracket 21 is fixedly connected to the carding machine body 1. By fixing the bracket 21 to the carding machine body 1, the cotton roll positioning mechanism 2 is ensured to be firmly installed, providing a solid foundation for the stable transportation and positioning of the cotton roll, and avoiding vibration or deviation affecting the accuracy and efficiency of the carding operation.

[0034] Furthermore, the shaft rod 29 is inserted into the bracket 21. By inserting the shaft rod 29 into the bracket 21, the shaft rod 29 is ensured to stably and accurately position the cotton roll during movement, preventing the cotton roll from shifting or shaking during the combing process, thereby improving the stability and efficiency of the combing operation.

[0035] Furthermore, the end of the right-angle frame 210 away from the screw 26 is fixedly mounted on the outside of the carding machine body 1. By fixing the end of the right-angle frame 210 away from the screw 26 on the outside of the carding machine body 1, it is ensured that the screw 26 rotates stably and the force is balanced, avoiding bending or vibration of the screw 26 due to excessive cantilever, and ensuring the stability and reliability of the cotton roll positioning mechanism 2.

[0036] Furthermore, a cotton roll guiding mechanism 3 is provided on the left side of the cotton roll positioning mechanism 2. The cotton roll guiding mechanism 3 includes a connecting member 31 fixedly installed at the bottom of the bracket 21, a guide platform 32 fixedly installed at the left end of the connecting member 31, and a baffle 33 fixedly installed on the top of the guide platform 32. Through the design of the connecting member 31, the guide platform 32 and the baffle 33, the cotton roll is stably guided during the transportation process and smoothly rolls to the positioning position, thereby preventing the cotton roll from slipping and improving the continuity and stability of the cotton combing operation.

[0037] Furthermore, the guide platform 32 is in the shape of a right-angled trapezoid as a whole. The guide platform 32 is in the shape of a right-angled trapezoid as a whole, which facilitates the gradual lowering of the height of the cotton roll and the stable guidance during the transportation process, ensuring that the cotton roll can be smoothly rolled to the positioning position, thereby improving the continuity and stability of the cotton combing operation.

[0038] Furthermore, a paper tube exclusion groove is provided between the guide platform 32 and the positioning rod 23. The horizontal width of the paper tube exclusion groove is smaller than the diameter of the cotton roll, and the horizontal width of the paper tube exclusion groove is larger than the diameter of the paper tube. The paper tube exclusion groove ensures that the paper tube can smoothly fall along the groove after the cotton roll is used up. The width design prevents the cotton roll from falling in and ensures the passage of the paper tube to avoid blockage, thereby realizing the automation and smoothness of cotton roll replacement.

[0039] Furthermore, a cotton roll transport mechanism 4 is provided on the left side of the cotton roll guide mechanism 3. The cotton roll transport mechanism 4 includes a frame 41 fixedly installed on the left side of the guide platform 32. A cotton roll conveyor belt 42 is provided on the inner side of the frame 41. The cotton roll conveyor belt 42 on the inner side of the frame 41 realizes the automatic transportation of the cotton roll, reduces the physical burden of manual handling, improves work efficiency, and provides a stable and efficient cotton roll supply for the continuous operation of the carding machine.

[0040] When used specifically, the working principle of the utility model is as follows:

[0041] When using this carding machine, the operator first neatly places the cotton laps, which are wound from paper tubes, onto the lap conveyor belt 42. The lap conveyor belt 42 is designed to automatically transport the laps from the storage or supply area to the carding machine's working area, thereby reducing the physical burden of manually handling the laps. This improvement directly addresses the issues mentioned in the background art regarding manual lap placement, which results in high physical exertion and low work efficiency.

[0042] When the carding machine body 1 is ready for carding, the lap conveyor belt 42 is activated, transporting the lap toward the lap guide mechanism 3 at a steady speed and force. The lap guide mechanism 3 is fixed to the bottom of the bracket 21 by a connector 31. The guide platform 32 atop it is designed as a right-angled trapezoidal structure. This design not only helps to guide the lap stably during conveyance, but also ensures that the lap rolls smoothly between the curved block 22 and the positioning rod 23 when it reaches the designated position. A baffle 33 is also installed on the top of the guide platform 32 to prevent the lap from sliding due to external forces during conveyance.

[0043] When the cotton roll reaches the curved block 22 and positioning rod 23, their combined structure effectively restricts the horizontal movement of the cotton roll, ensuring its stability during subsequent processing. At this point, the dual-axis motor 25 is activated, causing it to rotate in the forward direction. The two output ends of the dual-axis motor 25 respectively drive two screws 26, which are mounted parallel and symmetrically below the gantry 24.

[0044] The external threads of screw 26 tightly mate with the internal threads of ball screw 27. This design ensures that as screw 26 rotates, ball screw 27 moves precisely along its axis. A linkage rod 28 is fixed to the bottom of ball screw 27, and a shaft 29 is fixed inside linkage rod 28. As ball screw 27 moves, linkage rod 28 and shaft 29 move inward accordingly, until shaft 29 penetrates the ends of the paper tube inside the cotton roll. This step limits the vertical position of the cotton roll, further enhancing its stability during the carding process.

[0045] As the carding process progresses, the cotton roll is gradually consumed, its diameter gradually decreasing. When the cotton roll on shaft 29 is exhausted, the dual-shaft motor 25 is activated to rotate in the opposite direction, causing the linkage rod 28 and shaft 29 to move outward until shaft 29 is completely free of the paper tube. At this point, the paper tube, freed from the restraint of shaft 29, naturally falls through the paper tube ejection slot located between the guide platform 32 and the positioning rod 23. The design of the paper tube ejection slot ensures smooth paper tube ejection while preventing clogging by cotton rolls or paper tube fragments.

[0046] The lap conveyor belt 42 is then restarted to deliver the next lap to the guide platform 32. Under the influence of gravity, the new lap rolls along the guide platform 32 to between the curved block 22 and the positioning rod 23, ready for the next round of carding. This entire process automatically replaces laps without manual intervention, significantly improving production efficiency and reducing operator workload.

[0047] In summary, the carding machine device effectively solves the problems of high physical exertion and low work efficiency caused by manual placement of cotton rolls mentioned in the background technology through the design of automated transportation, precise positioning and automatic replacement of cotton rolls, providing strong support for automated production in the textile industry.

[0048] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
