Embodiments

[0037] Referring to Figures 1 and 2, a fine opening machine includes a casing 1, which forms the main frame. A support column 3 is installed at the bottom of the casing 1 to elevate the entire casing 1. A cotton inlet 103 is located at the top of the casing 1, through which waste cotton enters the equipment. A cotton inlet channel 101 communicating with the cotton inlet 103 is provided inside the casing 1 to ensure that the waste cotton can smoothly enter the subsequent processing area. Simultaneously, a cotton outlet channel 102 is also provided inside the casing 1 for outputting the processed waste cotton.

[0038] The machine casing 1 houses motor-driven beaters, one side of which connects to the cotton inlet channel 101 and the other side to the cotton outlet channel 102. In this embodiment, there are four beaters: a first beater 21, a second beater 22, a third beater 23, and a fourth beater 24. These four beaters work together within the machine casing 1 to break up the cotton. The second beater 22, the third beater 23, and the fourth beater 24 have the same outer diameter, which is smaller than the outer diameter of the first beater 21. This difference in outer diameter helps to achieve differentiated breaking-up effects in different beater areas.

[0039] The second beater 22, the third beater 23, and the fourth beater 24 are located on one side of the cotton inlet channel 101, working together to initially break up the fallen cotton. Specifically, the second beater 22 is located at the bottom and rotates counterclockwise, the third beater 23 is located in the middle and rotates clockwise, and the fourth beater 24 is located at the top and rotates counterclockwise. The second beater 22 and the third beater 23 interact to initially break up the fallen cotton and push it towards the first beater 21; the third beater 23 and the fourth beater 24 also interact to initially break up the fallen cotton and push it towards the first beater 21.

[0040] The first beater 21 is located on one side of the cotton outlet channel 102 and rotates clockwise. Its main function is to further comb and disperse the cotton that has been initially dispersed, ensuring that the cotton reaches the ideal loosening state. Through this multi-stage beater arrangement, with different rotation directions and position layouts, the cotton can be fully dispersed, reducing fine cotton accumulation and improving the overall processing efficiency and cotton quality of the fine opening machine.

[0041] A pair of motor-driven feeding rollers 41 and 42 are installed at the bottom of the cotton inlet channel 101. These feeding rollers 41 and 42 are typically made of a material with appropriate surface roughness, such as a rubber roller with a fine texture, to increase friction with the cotton waste and ensure stable and uniform delivery of the waste to the subsequent processing area. The feeding rollers 41 and 42 can rotate synchronously via gear transmission, chain transmission, or other means to ensure continuous feeding.

[0042] In this embodiment, to effectively prevent a large amount of cotton from falling through the gap between the feeding rollers, the structure and installation method of the feeding rollers 41 and 42 were optimized. Specifically, a pair of parallel feeding rollers 41 and 42 were set up, connected by gear transmission. This gear transmission method is simple in structure and reliable in transmission, ensuring that the two feeding rollers rotate synchronously at the same linear speed, so that the cotton is evenly stressed and smoothly conveyed during the feeding process. At the same time, the gap between the two feeding rollers 41 and 42 is strictly controlled and set to less than 5 mm. Such a small gap can ensure that the fine cotton passes through smoothly, while minimizing the occurrence of a large amount of cotton falling through the gap.

[0043] A first baffle 43 and a second baffle 44 are provided inside the housing 1 on both sides of the feeding rollers 41 and 42. This effectively prevents the cotton from scattering to both sides during the conveying process. A hollow groove is provided at the bottom of the housing 1 defined by the first baffle 43 and the second baffle 44. The groove can be rectangular or rectangular in shape to facilitate the falling of fine cotton.

[0044] A conveying mechanism 5 is installed at the bottom of the casing 1. A wind collector 6 is installed on one side of the conveying mechanism 5. The wind collector 6 is funnel-shaped with its wide opening facing the conveyor belt, which can better collect fine cotton. The wind collector 6 is connected to an exhaust fan through a pipe. The conveying mechanism 5 transports the fine cotton falling from the perforated groove to the wind collector 6. After the exhaust fan is started, it generates negative pressure to draw the fine cotton away, preventing the fine cotton from accumulating inside the equipment and solving the problem of inconvenient cleaning caused by the accumulation of fine cotton.

[0045] In this embodiment, the conveying mechanism 5 is a belt conveyor. The conveyor belt of the belt conveyor is precisely positioned directly below the perforated groove, ensuring that the fine cotton falling from the perforated groove can fall directly onto the conveyor belt, achieving effective collection and conveying.

[0046] To prevent fine cotton from scattering from both sides of the conveyor belt during transport, a third baffle 51 and a fourth baffle 52 are installed on the supports on both sides of the conveyor belt, respectively. The third baffle 51 and the fourth baffle 52 can be made of metal plates with certain strength and wear resistance. The upper ends of both are close to or abut against the bottom of the casing 1, forming a relatively closed conveying space to prevent fine cotton from leaking out and to ensure that the fine cotton can be stably and efficiently conveyed to the subsequent processing stage.

[0047] In this embodiment, a guide plate 7 is provided inside the housing 1. The guide plate 7 forms one side wall of the cotton inlet channel 101, and it is inclined towards the beater side. This inclined design is not arbitrary, but is carefully considered based on the characteristics of cotton drop conveying, with the aim of guiding the cotton drop smoothly into the beater area and avoiding the cotton drop from being stuck or disordered during the conveying process.

[0048] Specifically, the tilt angle of the guide plate 7 is strictly controlled between 30° and 60°. Within this angle range, the cotton can slide more smoothly towards the beater area by its own gravity and the conveying force of the feed roller, effectively reducing the accumulation of cotton in front of the feed roller, ensuring the continuous and stable operation of the fine opening machine, and improving the cotton handling efficiency.

[0049] In this embodiment, a guide plate 7 is provided on one side of the feed roller 42. As described above, the guide plate 7 is one side wall of the cotton inlet channel 101 and is inclined towards the beater side, which serves to guide the cotton to smoothly enter the beater area. A flipping plate 81 is arranged on the other side of the feed roller 41.

[0050] One end of the tilting plate 81 is hinged to the housing 1 via a pin or other hinged connection, allowing it to rotate around the hinge point. The other end of the tilting plate 81 rests on a support block 9, which is securely fixed to the switch door 10. A gas spring 82 is also installed inside the housing 1, with one end hinged to the tilting plate 81 and the other end hinged to the housing 1. This structure assists in the smooth tilting of the tilting plate 81. When the switch door 10 is opened, the support block 9 moves with the switch door 10. At this time, the tilting plate 81 is supported only by the gas spring 82. After the operator enters, they can manually tilt the plate 81 for easy observation or cleaning of the equipment.

[0051] In addition, the flip plate 81 is provided with a first arc groove corresponding to the first beater 21 and a second arc groove corresponding to the second beater 22. The design of these arc grooves can prevent the flip plate 81 from interfering with the beaters when flipping or stationary, ensuring the normal operation of the beaters, and also ensuring the compactness and stability of the overall structure of the equipment.

[0052] The precision opening machine provided by this utility model is a complete machine with a control system, power supply system, air supply system, vacuum system, etc., and realizes orderly and coordinated operation of each link through a unified interface and operation instructions.

[0053] The fine opening machine provided by this utility model effectively solves a series of problems caused by the accumulation of fine cotton during operation, through the feeding rollers 41 and 42 and the subsequent conveying mechanism 5. When the feeding rollers 41 and 42 rotate, the friction between them and the falling cotton stably and continuously conveys the fine cotton at the bottom to the conveying mechanism 5 below. The conveying mechanism operates, transporting the fine cotton to a specific position, where it is then smoothly exhausted by the exhaust fan. This process forms a highly efficient fine cotton handling mechanism, preventing the large-scale accumulation of fine cotton inside the equipment and avoiding problems such as malfunctions and accelerated wear of components caused by fine cotton accumulation, thus ensuring the stable operation and long service life of the fine opening machine.

[0054] When it is necessary to clean the fine cotton deposits at the beater, simply open the switch door 10. The support block 9 moves with the switch door, and the gas spring 82 assists the tilting plate 81 to tilt smoothly, providing the operator with a spacious and convenient cleaning space. This design greatly improves the convenience of equipment cleaning, reduces the time and labor costs required for cleaning, and enables the equipment to quickly return to good working condition, thereby improving overall production efficiency.
