Description
Technical Field
[0001] The present application relates to the technical field of cotton plucking machines, and in particular to a cotton plucking mechanism of a cotton plucking machine. Background Art
[0002] Before spinning, the cotton must be sucked into the mixing or spinning system for mixing, cleaning or opening. The plucker is the first process in the opening and cleaning machine. Its working principle is to open, comb and remove impurities from the delivered cotton rolls or the cotton layer supplied by the cotton box.
[0003] However, in order to meet the increasing demand for cotton in subsequent production and to increase the cotton picking speed, it is often necessary to increase the working speed of the cotton picking structure of the cotton picking machine. This causes the cotton picked up by the cotton picking mechanism to be too tightly combined with the cotton picking structure, making it difficult to enter the feeding pipe, resulting in reduced cotton picking efficiency. Therefore, it still needs to be improved. Utility Model Content

[0009] By adopting the above technical solution, the air blast duct increases the lift on the cotton wool, thereby reducing the conveying pressure of the exhaust duct, and the air blast manifold ensures uniform air intake to prevent the cotton wool from getting stuck.
[0010] Preferably, the swinging structure includes a swinging shaft and a swinging air plate, the swinging shafts are arranged at intervals and rotatably connected to the side walls of the core shaft; the swinging air plate is fixed to the swinging shaft, and the swinging air plate extends along the rotation direction of the core shaft; the cotton grabbing beater is fixed to the rear side end of the swinging air plate relative to the rotation direction of the core shaft and extends away from the core shaft.

The wind direction control structure in the blast structure can adjust the angle of the swing structure to swing left and right to shake off the cotton wool, or increase the wind force by concentrating on a certain place to clean the cotton grab beater, thereby preventing jamming and improving cotton discharge efficiency.
[0016] 2. The blast duct increases the lift on the cotton wool, thereby reducing the conveying pressure of the exhaust duct. The blast manifold ensures uniform air intake to prevent cotton wool from getting stuck;
[0017] 3. The swinging wind plate cooperates with the swinging shaft to keep stable when picking cotton, and is easier to deflect and rotate stably when unloading cotton;

DETAILED DESCRIPTION
[0023] The present application is further described in detail below in conjunction with the accompanying drawings.
[0024] The present application embodiment discloses a cotton plucking mechanism of a cotton plucking machine, referring to Figure 1 , 2 , including a shaft shell 3 moving along the upper surface of the cotton roll, a top of the shaft shell 3 is provided with an exhaust duct 4 extending upward, a core shaft 9 is arranged in the shaft shell 3 and rotatably connected, the core shaft 9 is provided with a cotton grabbing beater 5, the core shaft 9 rotates and drives the cotton grabbing beater 5 to grab the cotton, and the cotton is sucked into the exhaust duct 4 for subsequent processing; a cotton pressing roller 2 for flattening the cotton layer is rotatably connected to the side of the shaft shell 3 relative to the blowing structure 7.
[0025] Reference Figure 2 , 3 The cotton grabbing beater 5 is connected to the core shaft 9 through a swinging structure 6. The swinging structure 6 includes a swinging shaft 61 and a swinging air plate 62. The swinging shafts 61 are arranged at intervals and rotatably connected to the side wall of the core shaft 9; the swinging air plate 62 is fixed to the swinging shaft 61, and the swinging air plate 62 extends along the rotation direction of the core shaft 9; the cotton grabbing beater 5 is fixed to the rear side end of the swinging air plate 62 relative to the rotation direction of the core shaft 9 and extends in the direction away from the core shaft 9.
[0026] Reference Figure 2 , 3 The swing shaft 61 is arranged at the center of the swing air plate 62; when the cotton grabbing beater 5 is grabbing cotton, the swing shaft 61 is located in front of the cotton grabbing beater 5, and the cotton grabbing beater 5 is not easy to swing left and right, and the cotton grabbing effect is better; when the swing air plate 62 is close to the exhaust duct 4, the weight of the front and rear sides of the swing air plate 62 is balanced, which makes it easier to rotate and less likely to produce dead points.
[0027] Reference Figure 2 , 3The swinging air plate 62 is driven to rotate by the blowing structure 7. The blowing structure 7 includes a blowing duct 71, a blowing manifold 72 and a blower 73. The blowing duct 71 is connected to the rising side of the rotating shaft housing 3 close to the rotating shaft, and the blowing duct 71 is inclined upward toward the side close to the exhaust duct 4 to provide a stronger lift airflow; one end of a plurality of blowing manifolds 72 is respectively connected to the side of the blowing duct 71 opposite to the rotating shaft housing 3, and is spaced apart corresponding to the swinging structure 6, and the other ends are close to each other and connected; the blowers 73 are respectively fixed to the connected ends of the blowing manifolds 72, so that the air volume at each place of the blowing duct 71 is uniform.
[0028] Reference Figure 2 , 3 A wind direction control structure 8 is provided on the blast duct 71, and the wind direction control structure 8 includes a wind direction control plate 81 and a stepper motor 82. The wind direction control plates 81 are respectively accommodated and rotatably connected in the blast duct 71, and the wind direction control plates 81 are arranged at a position corresponding to the position between the two swinging air plates 62; the stepper motor 82 is fixed above the blast duct 71, and the output shaft of the stepper motor 82 is fixed to the rotating shaft of the wind direction control plate 81.
[0029] The working process of the present application is as follows: the cotton grabbing beater 5 is driven to rotate by the core shaft 9, grabs the cotton roll into cotton wool and rotates it to the exhaust duct 4. When it rotates to the blast duct 71, the blast duct 71 generates an upward airflow to the cotton grabbing beater 5, driving the cotton wool into the exhaust duct 4; at the same time, the stepper motor 82 controls the wind direction control plate 81 to swing left and right, driving the swinging wind plate 62 to swing left and right to throw off the cotton wool stuck on the cotton grabbing beater 5, so that the cotton wool can be better separated from the cotton grabbing beater 5, thereby improving the cotton grabbing efficiency.
[0030] When it is found that a lot of cotton wool is stuck in the cotton grabbing beaters 5 of a certain route, the stepper motor 82 is adjusted to aim the multiple wind direction control plates 81 at the cotton grabbing beaters 5 for squeezing the cotton wool and blow strong air to help the cotton wool get rid of the cotton grabbing beaters 5, thereby ensuring efficient cotton grabbing.
[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
