Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a cotton plucking machine. Background Art

[0002] A cotton plucker, also known as a bale plucker, is a machine that grabs cotton fibers from cotton bales in a cotton opening and cleaning unit. There are straight-moving cotton pluckers and ring-type cotton pluckers. The two types of cotton pluckers have the same cotton plucking principle, which is to use a high-speed rotating cotton beater to grab small balls of cotton, and then use an air pump to suck them into the cotton suction hood and send them to subsequent cotton openers, cotton blenders or other equipment.

[0003] A large disc cotton plucking machine disclosed in a Chinese patent with announcement number CN220846379U includes: a large cylinder, a central column and a cotton plucking mechanism. The cotton plucking mechanism includes a cotton suction hood, a cotton plucking roller and a connecting pipe. The cotton suction hood is fixedly installed on the lower side of the mounting frame. The lower side of the cotton suction hood is open and a rotating shaft is rotatably arranged at the opening. The cotton plucking roller is fixedly sleeved on the rotating shaft, and a plurality of cotton plucking teeth are provided on the cotton plucking roller.

[0004] In the above technology, the cotton grabbing teeth on the cotton grabbing roller are arranged flatly, that is, there are a lot of gaps between two adjacent groups of cotton grabbing teeth. When the cotton grabbing roller rotates, the effective cotton grabbing range in the axial direction of the cotton grabbing roller is small, and there will be a blind spot for cotton grabbing, resulting in low cotton grabbing efficiency per unit length of the cotton grabbing roller, thereby affecting the amount of cotton fed into the cotton bin per unit time, which is insufficient. Utility Model Content

[0005] In order to improve the cotton picking efficiency of the rotating shaft, the present application provides a cotton picking machine.

[0006] The present application provides a cotton plucking machine that adopts the following technical solution:

[0007] A cotton plucking machine comprises a cotton releasing pool, a cotton plucking mechanism is arranged on the cotton releasing pool, the cotton plucking mechanism comprises an intermediate column coaxially arranged with the cotton releasing pool, a cotton plucking frame is rotatably arranged on the intermediate column, a cotton plucking roller is rotatably arranged on the cotton plucking frame, a rotating part for driving the cotton plucking roller to rotate is arranged on the cotton plucking frame, a plurality of cotton plucking teeth are arranged on the cotton plucking roller, and the plurality of cotton plucking teeth are spirally distributed along the axis of the cotton plucking roller, and a cotton suction component for sucking cotton threads grabbed by the cotton plucking teeth is arranged on the cotton plucking frame.

[0008] By adopting the above technical scheme, when the cotton suction component needs to absorb the cotton threads grabbed by the cotton grabbing teeth, the rotating part drives the cotton grabbing roller to rotate. Since the cotton grabbing teeth are spirally distributed along the axis of the cotton grabbing roller, when the cotton grabbing roller rotates, the cotton threads can be grabbed along the axis direction of the cotton grabbing roller, thereby reducing the cotton grabbing blind area of ​​the cotton grabbing teeth on the cotton grabbing roller and increasing the cotton grabbing range of the cotton grabbing roller, thereby improving the cotton grabbing efficiency of the cotton grabbing roller.

[0009] Optionally, the cotton suction assembly includes a lifting frame slidably arranged on the cotton picking frame, the cotton picking roller is rotatably arranged on the lifting frame, a cotton suction bucket is arranged on the lifting frame and above the cotton picking roller, the cotton suction bucket is connected with a bellows, the bellows is connected with an external cotton bin, and a driving member for driving the lifting frame to rise and fall is arranged on the lifting frame.

[0010] By adopting the above technical scheme, after the upper layer of cotton threads in the cotton release pool are grabbed by the cotton grabbing roller, the driving component drives the lifting frame to descend, and the bellows is pulled up, so that the lower layer of cotton threads in the cotton release pool can be grabbed by the cotton grabbing roller, which is conducive to facilitating the cotton grabbing roller to grab the cotton threads in the vertical direction in the cotton release pool.

[0011] Optionally, the rotating member includes a cotton shaft motor which is arranged on the lifting frame and electrically connected to a control system, and a transmission belt is wound between an output shaft of the cotton shaft motor and the cotton grabbing roller.

[0012] By adopting the above technical solution, the worker starts the cotton shaft motor through the control system, and the cotton shaft motor drives the cotton grabbing roller to rotate through the transmission belt, so as to realize the cotton grabbing roller's function of grabbing cotton.

[0013] Optionally, the driving member includes a lifting screw arranged on the lifting frame, a driving gear is rotatably arranged on the cotton picking frame, the lifting screw is threadedly connected to the driving gear, a lifting motor electrically connected to the control system is arranged on the cotton picking frame, a chain is wound between the output shaft of the lifting motor and the driving gear, and a guide column parallel to the axis of the lifting screw is arranged on the lifting frame, and the guide column is slidably matched with the cotton picking frame.

[0014] By adopting the above technical solution, when the height of the lifting frame needs to be lowered, the worker starts the lifting motor through the control system, and the lifting motor drives the driving gear to rotate through the chain. Since the driving gear is rotatably connected to the cotton picking frame, the position of the driving gear is immutable. The driving gear rotates to move the lifting screw downward, and under the limiting action of the guide column, the lifting frame moves downward.

[0015] Optionally, a plurality of groups of the cotton grabbing teeth are arranged in the axial direction of the cotton grabbing roller, and a dividing strip is arranged between two adjacent groups of the cotton grabbing teeth, and the dividing strip is arranged on the lifting frame.

[0017] Optionally, a slide rail is coaxially arranged outside the cotton release pool, a roller is rotatably arranged on the cotton picking frame, the roller rolls with the slide rail, and a rotating motor electrically connected to the control system is arranged on the cotton picking frame, and the output shaft of the rotating motor drives the roller to rotate.

[0018] By adopting the above technical solution, workers start the rotating motor through the control system, and the rotating motor drives the roller to rotate. The roller rolls on the slide rail, causing the cotton grabbing frame to rotate around the middle column, thereby achieving the effect of grabbing the cotton threads on the same layer in the cotton pool.

[0019] Optionally, an outer cylinder seat is coaxially rotatably arranged on the middle column, a winding motor electrically connected to a control system is arranged on the middle column, the outer cylinder seat is arranged on an output shaft of the winding motor, and the cotton picking frame is rotatably arranged on the outer cylinder seat.

[0020] By adopting the above technical solution, workers start the shaft-wrap motor through the control system, and the output shaft of the shaft-wrap motor drives the outer cylinder seat to rotate, and the outer cylinder seat drives the cotton picking frame to rotate around the middle column. At the same time, when the ground is uneven and causes the slide rail to be uneven, the cotton picking frame can rotate around the rotation center on the outer cylinder seat again during the process of rotating around the middle column, so that the cotton picking frame can automatically adjust the angle through the rotation center on the outer cylinder seat and move smoothly, reducing the requirements for the flatness of the factory floor.

[0021] Optionally, a shock-absorbing ring is provided on the roller, and the shock-absorbing ring is used for rolling cooperation with the slide rail.

[0022] By adopting the above technical solution, when the factory floor causes the slide rail to be uneven, the shock-absorbing ring can reduce the vibration degree of the cotton grabbing frame during the process of the roller driving the cotton grabbing frame to rotate, which is beneficial to improving the stability of the cotton grabbing frame during operation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the cotton suction component needs to absorb the cotton threads caught by the cotton grabbing teeth, the rotating part drives the cotton grabbing roller to rotate. Since the cotton grabbing teeth are spirally distributed along the axis of the cotton grabbing roller, when the cotton grabbing roller rotates, the cotton threads can be caught along the axis direction of the cotton grabbing roller, which reduces the cotton grabbing blind area of ​​the cotton grabbing teeth on the cotton grabbing roller and increases the cotton grabbing range of the cotton grabbing roller, thereby improving the cotton grabbing efficiency of the cotton grabbing roller;

[0025] 2. When the height of the lifting frame needs to be lowered, the worker starts the lifting motor through the control system. The lifting motor drives the driving gear to rotate through the chain. Since the driving gear is rotatably connected to the cotton grabbing frame, the position of the driving gear cannot be changed. The driving gear rotates to move the lifting screw downward, and under the restriction of the guide column, the lifting frame moves downward;

[0026] 3. The worker starts the winding motor through the control system. The output shaft of the winding motor drives the outer cylinder seat to rotate, and the outer cylinder seat drives the cotton picking frame to rotate around the middle column. At the same time, when the ground is uneven and the slide rail is uneven, the cotton picking frame can rotate around the rotation center on the outer cylinder seat again during the rotation around the middle column, so that the cotton picking frame can automatically adjust the angle through the rotation center on the outer cylinder seat and move smoothly, reducing the requirements for the flatness of the factory floor.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The rotating member 24 includes a cotton shaft motor 241 bolted to the lifting frame 261 and electrically connected to the control system. A transmission belt 242 is wound between the output shaft of the cotton shaft motor 241 and the cotton grabbing roller 23. A plurality of cotton grabbing teeth 25 are welded in the axial direction of the cotton grabbing roller 23. Each group of cotton grabbing teeth 25 is composed of a plurality of cotton grabbing teeth 25 spirally arranged around the axis of the cotton grabbing roller 23. A dividing strip 3 is arranged between two adjacent groups of cotton grabbing teeth 25, and the dividing strip 3 is bolted to the bottom of the lifting frame 261.

[0038] When the cotton suction bucket 262 needs to absorb the cotton threads on the cotton picking roller 23, the worker starts the cotton shaft motor 241 through the control system. The output shaft of the cotton shaft motor 241 drives the cotton picking roller 23 to rotate through the transmission belt 242. The cotton picking teeth 25 on the cotton picking roller 23 grab the cotton threads in the cotton pool 1. Since the cotton picking teeth 25 are distributed in a spiral shape along the axis of the cotton picking roller 23, when the cotton picking roller 23 rotates, the cotton picking blind area of ​​the cotton picking teeth 25 on the cotton picking roller 23 is reduced.

[0039] At the same time, the control system starts the winding motor 8, the output shaft of the winding motor 8 drives the outer cylinder seat 7 to rotate, and the outer cylinder seat 7 drives the cotton picking frame 22 to rotate. During the rotation of the cotton picking frame 22, the wool strips 3 are pressed on the cotton threads in the cotton placing pool 1, and the balled cotton threads are flattened until the cotton picking teeth 25 on the cotton picking roller 23 can no longer grab the cotton threads during the rotation of the cotton picking frame 22.

A rotating motor 6 electrically connected to the control system is bolted to the cotton picking frame 22, and the output shaft of the rotating motor 6 drives the roller 5 to rotate.

[0042] The worker starts the lifting motor 2643 through the control system. The output shaft of the lifting motor 2643 drives the driving gear 2642 to rotate through the chain 2644. Since the position of the driving gear 2642 on the cotton grabbing frame 22 is immovable, the driving gear 2642 rotates to move the lifting screw 2641 downward.

[0043] Under the limiting effect of the guide column 2645, the lifting frame 261 moves downward for a distance, and then the control system starts the cotton shaft motor 241 and the winding shaft motor 8 again, and the cotton grabbing teeth 25 on the cotton grabbing roller 23 repeatedly grab the cotton threads in the cotton placing pool 1 until the cotton threads in the cotton placing pool 1 are grabbed or the cotton suction bucket 262 absorbs enough cotton threads.

[0044] The implementation principle of a cotton picking machine in an embodiment of the present application is as follows: when the cotton suction bucket 262 needs to suck the cotton threads on the cotton picking roller 23, the worker starts the cotton shaft motor 241 through the control system, and the output shaft of the cotton shaft motor 241 drives the cotton picking roller 23 to rotate through the transmission belt 242, and the cotton picking teeth 25 on the cotton picking roller 23 grab the cotton threads in the cotton pool 1. Since the cotton picking teeth 25 are distributed in a spiral shape along the axis of the cotton picking roller 23, when the cotton picking roller 23 rotates, the cotton picking blind area of ​​the cotton picking teeth 25 on the cotton picking roller 23 is reduced.

[0045] At the same time, the control system starts the winding motor 8, the output shaft of the winding motor 8 drives the outer cylinder seat 7 to rotate, and the outer cylinder seat 7 drives the cotton picking frame 22 to rotate. During the rotation of the cotton picking frame 22, the wool strips 3 are pressed on the cotton threads in the cotton placing pool 1, and the balled cotton threads are flattened until the cotton picking teeth 25 on the cotton picking roller 23 can no longer grab the cotton threads during the rotation of the cotton picking frame 22.

[0046] The worker starts the lifting motor 2643 through the control system. The output shaft of the lifting motor 2643 drives the driving gear 2642 to rotate through the chain 2644. Since the position of the driving gear 2642 on the cotton grabbing frame 22 is immovable, the driving gear 2642 rotates to move the lifting screw 2641 downward.

[0047] Under the limiting effect of the guide column 2645, the lifting frame 261 moves downward for a distance, and then the control system starts the cotton shaft motor 241 and the winding shaft motor 8 again, and the cotton grabbing teeth 25 on the cotton grabbing roller 23 repeatedly grab the cotton threads in the cotton placing pool 1 until the cotton threads in the cotton placing pool 1 are grabbed or the cotton suction bucket 262 absorbs enough cotton threads.
