Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a cotton roll forming device for cotton spinning production. Background Technology

[0002] With the development of society, cotton lap forming devices are being used more and more widely. Cotton spinning production refers to the industrialized production process that uses cotton as raw material and processes loose cotton fibers into cotton yarn and thread with a certain strength and uniformity through a series of processes. The cotton lap forming device is the core supporting equipment at the end of the cotton cleaning process in cotton spinning production. It is a special mechanism that facilitates the feeding of "cotton laps" into the subsequent carding machine.

[0003] In existing technologies, some cotton lap forming devices in cotton spinning production mainly consist of a feeding mechanism, a drafting mechanism, a winding mechanism, and an auxiliary control structure. The feeding mechanism uniformly conveys the opened cotton layer. The drafting mechanism uses multiple pairs of rollers to stretch the cotton layer to a specified thickness to ensure uniformity. The core of the winding mechanism is the winding roller and the cotton lap mandrel. Through the coordinated rotation of the two, the cotton layer is wound layer by layer. The auxiliary control structure includes a tension adjustment device, which can control the tightness and length of the cotton lap in real time, providing qualified raw materials for subsequent spinning processes.

[0004] In existing technologies, some cotton roll forming devices often fail to achieve uniform pressure during the pressing and winding of cotton fibers, resulting in the cotton rolls failing to achieve a uniform and stable compaction effect during forming. This not only easily leads to loose cotton rolls and poor interlayer adhesion, but also affects the stability and processing quality of subsequent spinning processes, reducing production efficiency and product qualification rate. Therefore, a cotton roll forming device for cotton spinning production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cotton roll forming device for cotton spinning production, which aims to improve the problem that some existing cotton roll forming devices are difficult to compact during forming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cotton roll forming device for cotton spinning production includes a support frame, a roll forming mechanism fixedly connected to the top of the support frame, a compact forming mechanism fixedly connected to the top of the support frame, an adjustment mechanism fixedly connected to the top of the support frame, and a cotton roll fabric slidably connected to the top of the roll forming mechanism. The compacting and forming mechanism includes two support frames. The bottom of the two support frames is fixedly connected to the top of the support frame. A fastening column is fixedly connected to an adjacent side of the two support frames. A sliding plate is slidably connected inside each support frame. A damping telescopic column is fixedly connected to the left side of the sliding plate. A telescopic spring is sleeved on the outside of the damping telescopic column. A fixed base plate is fixedly connected to the right side of the sliding plate. A pushing component is fixedly connected to the top of the support frame. As a further description of the above technical solution: The pushing assembly includes two cylinders, the bottoms of the two cylinders are fixedly connected to the top of the support frame, and the driving end of the cylinders is fixedly connected to a fastening arc plate. As a further description of the above technical solution: The left side of each pair of the telescopic springs is fixedly connected to the inside of the support frame, and the left side of each pair of the damping telescopic columns is fixedly connected to the inside of the support frame. As a further description of the above technical solution: The adjustment mechanism includes two support blocks, the bottoms of the two support blocks are fixedly connected to the top of the support frame, a fixed plate is fixedly connected to a side of the support blocks, and multiple adjustment slots are opened inside the other fixed plate. As a further description of the above technical solution: Two movable plates are slidably connected to the top of another fixed plate. A limiting plate is fixedly connected to the adjacent side of the movable plates, and a cotton roll is slidably connected to the adjacent side of the two limiting plates. As a further description of the above technical solution: The adjustment groove is slidably connected to a telescopic cylinder. Each telescopic cylinder has two grooves at its bottom. Each groove has two tension springs fixedly connected inside. A fixed rotating plate is fixedly connected to the opposite side of the multiple tension springs. The telescopic cylinder is slidably connected to the inside of the moving plate. As a further description of the above technical solution: The winding mechanism includes two support plates a, the bottom of the two support plates a is fixedly connected to the winding mechanism, the adjacent sides of the two support plates a are rotatably connected to the winding column, the top of the support frame is fixedly connected to two support plates b, and the adjacent sides of the two support plates b are fixedly connected to the guide roller. As a further description of the above technical solution: The bottom of the cotton roll is slidably connected to the top of the guide rod, the bottom of the cotton roll is rotatably connected to the outside of the winding column, and the bottom of the cotton roll is slidably connected to the top of the fastening arc plate.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the column gradually increases in size during the winding process, pushing the sliding plate to slide to the left within the support frame, which in turn pushes the telescopic spring and the damping telescopic column to move. The bottom of the cylinder pushes the arc plate to quickly tighten the cotton roll, while the sliding plate remains stable inside. The use of the damping telescopic column effectively reduces the damage when the spring rebounds, improves the stability of the equipment, optimizes the processing quality and production efficiency, and significantly improves the product qualification rate.

[0008] 2. In this utility model, the cooperation between the fixed plate and the adjusting groove, as well as the sliding mechanism of the moving plate, allows the spring to store force and enter the adjusting groove. When the fixed rotating plate reaches the horizontal position, it can firmly fix the cotton roll. The limiting plate effectively restricts the width of the cotton roll, ensuring the stability and accuracy of the processing process, thereby improving the practicality and adaptability of the device.

[0011] 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

[0012] A cotton lap forming device for cotton spinning production, as shown in the reference. Figures 1 to 3 The device includes a support frame 1, which is the basic load-bearing component of the entire cotton roll forming device. Its main function is to provide stable installation for core functional components such as the roll forming mechanism 2, the compact forming mechanism 4, and the adjustment mechanism 5. The top of the support frame 1 is fixedly connected to the roll forming mechanism 2, which includes two support plates a22. The support plates a22 are direct support components for the take-up column 21, and their main function is to provide rotational support and positioning for the take-up column 21, ensuring that the axial position of the take-up column 21 remains fixed during rotation. The bottom of the two support plates a22 is fixedly connected to the roll forming mechanism 2, and the take-up column 21 is rotatably connected to the adjacent side of the two support plates a22. The take-up column 21 is the roll forming machine. The core execution component of structure 2 is mainly used to wind and rewind the guided cotton roll 3. It is the direct carrier for cotton roll forming. The top of the support frame 1 is fixedly connected to two support plates b23. The support plates b23 are the support and positioning components of the guide roller 24. Their main function is to provide a stable installation base for the guide roller 24. The guide roller 24 is fixedly connected to the adjacent side of the two support plates b23. The guide roller 24 is the conveying and guiding component of the cotton roll 3. The bottom of the cotton roll 3 is slidably connected to the top of the guide roller 24. The cotton roll 3 is the processing object of the device. The bottom of the cotton roll 3 is rotatably connected to the outside of the winding column 21. The bottom of the cotton roll 3 is slidably connected to the top of the fastening arc plate 472. Specifically, the cotton roll 3 is first conveyed and guided by the guide roller 24 supported by the support plate b23. After being guided, the cotton roll 3 is wound into the rolling mechanism 2. It begins to be wound and rolled up outside the winding column 21 supported by the rotating support plate a22. During the winding process, the fastening arc plate 472 of the compacting and forming mechanism 4 keeps in contact with the top of the cotton roll 3 to help the cotton roll be compacted. The adjusting mechanism 5 adjusts the relevant components in real time according to the cotton roll forming requirements.

[0013] A compacting mechanism 4 is fixedly connected to the top of the support frame 1. The compacting mechanism 4 includes two support frames 41, which serve as the mounting base and motion guide for the compacting mechanism 4. The bottoms of the two support frames 41 are fixedly connected to the top of the support frame 1. A fastening post 43 is fixedly connected to one of the adjacent sides of the two support frames 41. The fastening post 43 is the direct action component for radial compaction of the cotton roll. Its main function is to maintain continuous contact with the surface of the cotton roll during the winding process of the winding post 21, and apply radial pressure to the cotton roll through elastic force to ensure that the cotton roll gradually becomes compact during winding. A sliding plate 42 is slidably connected inside each support frame 41. The sliding plate 42 connects the fastening post 43 to the damping telescopic post 44 and the telescopic spring 45, transmitting the force generated by the increase in the diameter of the cotton roll by the winding post 21 to the elastic part. The sliding plate 42 is fixedly connected to the left side of the sliding plate 42. The damping telescopic column 44 is a buffer and shock absorption component of the compacting mechanism 4. Its main function is to cooperate with the telescopic spring 45 to provide damping force during the sliding of the sliding plate 42, reduce the rebound speed of the telescopic spring 45, and avoid the impact and damage to the mechanism caused by the sudden change of elastic force. The telescopic spring 45 is sleeved on the outside of the damping telescopic column 44. The telescopic spring 45 provides continuous elastic restoring force for the sliding plate 42 and the fastening column 43, ensuring that the fastening column 43 always keeps in contact with the cotton roll surface and applies stable compaction pressure. The right side of the sliding plate 42 is fixedly connected to the fixed base plate 46, and the top of the support frame 1 is fixedly connected to the push assembly 47. Specifically, when the winding column 21 is winding, the diameter of the cotton roll gradually increases and comes into contact with the fastening column 43. After the fastening column 43 is squeezed by the cotton roll, it drives the sliding plate 42 to slide inside the support frame 41. During the sliding process, the sliding plate 42 simultaneously drives the damping telescopic column 44 to retract and compresses the externally sleeved telescopic spring 45. At the same time, the fixed base plate 46 on the right side of the sliding plate 42 cooperates with the push component 47 to move. The telescopic spring 45 continuously provides elastic force, so that the fastening column 43 always keeps in contact with the surface of the cotton roll and applies pressure. The damping telescopic column 44 slows down the rebound speed until the cotton roll is tightly formed.

[0014] The pushing component 47 includes two cylinders 471. The cylinders 471 are the power source of the pushing component 47. Their main function is to provide linear thrust to drive the fastening arc plate 472 to move upward and apply concentrated pressure to the bottom of the cotton roll during the winding process, so as to achieve rapid and compact formation of the bottom of the cotton roll. The bottom of the two cylinders 471 is fixedly connected to the top of the support frame 1. The driving end of the cylinder 471 is fixedly connected to the fastening arc plate 472, which converts the thrust of the cylinder 471 into arc pressure on the bottom of the cotton roll, increases the contact area with the cotton roll, and ensures that the bottom of the cotton roll is uniformly compact. The left side of each pair of telescopic springs 45 is fixedly connected to the inside of the support frame 41, and the left side of each pair of damping telescopic columns 44 is fixedly connected to the inside of the support frame 41. The top of the support frame 1 is fixedly connected to the adjustment mechanism 5, and the top of the winding mechanism 2 is slidably connected to the cotton roll cloth 3. Specifically, the cotton roll 3 slides on top of the rolling mechanism 2 and enters the winding process. The adjustment mechanism 5 works in conjunction with the support frame 1. The support frame 41 moves together with the damping telescopic column 44 and the telescopic spring 45 to start the cylinder 471 of the push assembly 47, providing vertical thrust and driving the fastening arc plate 472 to move upward, applying pressure to the bottom of the cotton roll during winding, and working with the rolling mechanism 2 to complete the cotton roll winding operation, ensuring the winding process progresses.

[0015] Reference Figure 4 and Figure 5The adjusting mechanism 5 includes two support blocks 52, which are the basic support components of the adjusting mechanism 5. Their main function is to provide stable installation support for the fixed plate 51. The bottoms of the two support blocks 52 are fixedly connected to the top of the support frame 1. A fixed plate 51 is fixedly connected to the adjacent side of the support blocks 52. The fixed plate 51 is the core positioning and guiding component of the adjusting mechanism 5, and its main function is to provide sliding guidance for the moving plate 54. The other fixed plate 51 has multiple adjusting grooves 59 inside, which cooperate with the fixed rotating plate 58 to provide sliding guidance for the moving plate 54. The fixed position provides multiple positioning options, and the position of the moving plate 54 can be adjusted by selecting different adjustment slots 59, suitable for cotton rolls 3 of different widths. Two moving plates 54 are slidably connected to the top of another fixed plate 51. The moving plates 54 connect the limiting plate 53 to the fixed structure. By sliding on the fixed plate 51, the distance between the limiting plates 53 is adjusted to adapt to cotton rolls of different widths. The adjacent sides of the moving plates 54 are fixedly connected to the limiting plates 53. The relative setting of the two limiting plates 53 allows for horizontal adjustment of the cotton roll 3 during the winding process. To limit the movement, cotton rolls 3 are slidably connected to the adjacent sides of the two limiting plates 53. Telescopic cylinders 55 are slidably connected inside the adjusting groove 59. A fixed rotating plate 58 and tension springs 57 provide a mounting carrier. Through sliding cooperation with the moving plate 54, the fixed rotating plate 58 achieves telescopic movement, providing a structural basis for fixing the position of the moving plate 54. Two sliding grooves 56 are formed at the bottom of each telescopic cylinder 55. The sliding grooves 56 are motion guide components of the adjusting mechanism 5. Two tension springs 57 are fixedly connected inside each sliding groove 56. Spring 57 is the elastic reset component of adjustment mechanism 5. Its main function is to provide continuous tensile reset force for fixed rotating plate 58, ensuring that fixed rotating plate 58 can be reliably engaged in adjustment groove 59, thereby fixing the position of moving plate 54. Fixed rotating plate 58 is fixedly connected to the opposite side of multiple tension springs 57. Fixed rotating plate 58 is the locking actuator of adjustment mechanism 5. Its main function is to fix and unlock the position of moving plate 54 by engaging and disengaging with adjustment groove 59. The telescopic cylinder 55 is externally slidably connected to the inside of moving plate 54. Specifically, when adjustment is required, operate the fixed rotating plate 58 to overcome the tension of the tension spring 57 and retract along the slide groove 56, disengaging from the current adjustment groove 59. This pushes the moving plate 54 to slide on the fixed plate 51, causing the limiting plate 53 to move synchronously. When the limiting plate 53 moves to a position that matches the width of the cotton roll 3, release the fixed rotating plate 58, the tension spring 57 returns to its original position, and pushes the fixed rotating plate 58 into the corresponding adjustment groove 59. The telescopic cylinder 55 cooperates in positioning and fixes the position of the moving plate 54, completing the limit adjustment.

[0016] The implementation principle of this embodiment is as follows: The winding mechanism 2 starts working, and the winding column 21 rotates under the support of the support plate a22. After being guided by the guide roller 24, the cotton roll 3 is gradually wound around the outside of the winding column 21. As the cotton roll 3 is continuously wound, the diameter of the cotton roll outside the winding column 21 gradually increases. The cotton roll is in continuous contact with the fastening column 43 in the compacting mechanism 4 and generates a squeezing force, which pushes the fastening column 43 to drive the sliding plate 42 to slide to the left inside the support frame 41. The damping telescopic column 44 and the telescopic spring 45 on the left side of the sliding plate 42 are compressed simultaneously. The telescopic spring 45 generates an elastic reaction force, which continuously applies pressure to the cotton roll through the sliding plate 42 and the fastening column 43. To ensure the cotton roll remains tight during winding, the damping telescopic column 44 provides damping force when the telescopic spring 45 rebounds, preventing sudden changes in elastic force from impacting the mechanism. Simultaneously, the pushing component 47 at the top of the support frame 1 is activated, and the cylinder 471 drives the fastening arc plate 472 to move upward. The fastening arc plate 472 contacts the bottom of the cotton roll and applies uniform arc pressure, which, together with the tightening force, achieves rapid and tight forming of the bottom of the cotton roll. The fixed base plate 46 on the right side of the sliding plate 42 provides stable support for the movement of the fastening arc plate 472. The limiting plate 53 continuously limits the cotton roll cloth 3 to ensure that the cotton roll is formed neatly until the length of the cotton roll is completed and tightened.

[0017] According to the width adjustment mechanism 5 of the cotton roll 3 to be processed, press the fixed rotating plate 58 inside the telescopic cylinder 55 at the bottom of the moving plate 54. The fixed rotating plate 58 squeezes the tension spring 57 and retracts along the slide groove 56, causing it to disengage from the current adjustment groove 59. Then, push the moving plate 54 to slide on the top of the fixed plate 51, causing the limit plates 53 on both sides to move synchronously. When the distance between the limit plates 53 is adapted to the width of the cotton roll 3, release the fixed rotating plate 58, the tension spring 57 resets and pushes the fixed rotating plate 58 into the corresponding adjustment groove 59, completing the position fixation of the moving plate 54 and the limit plate 53, and realizing the limit adjustment of the cotton roll 3.
