Description

Technical Field

[0001] The invention belongs to the technical field of yarn processing equipment, and in particular relates to a disc-type plucking machine that adaptively adjusts humidification amount. Background Art

[0002] The disc plucker is one of the key equipment used in the cotton opening and cleaning process in the textile industry. It is mainly used to grab fibers from cotton bales or chemical fiber bales, and preliminarily loosen and mix them for use in subsequent processes. Its working principle is: multiple bales are arranged on a circular platform to form a ring-shaped cotton pile. The platform rotates slowly, and the cotton grabber moves radially to grab the fibers layer by layer. The beater tears and loosens the fibers into small pieces through blades or combing needles. Due to the rotation of the platform, fibers from different cotton bales are alternately grabbed to achieve preliminary mixing. The grabbed fibers are transported to the next equipment (such as a cotton blender or cotton opener) through the pipeline by airflow.

[0003] It should be noted that dry fibers (especially cotton or chemical fibers) are easily broken by the high-speed beaters of the cotton plucking machine, resulting in short fibers and neps. Synthetic fibers (such as polyester and acrylic) are prone to static electricity when rubbed in a dry environment, causing the fibers to fly, adsorb on equipment or clump together, affecting uniform grabbing and transportation. Therefore, the humidity of the cotton is particularly important when plucking.

[0004] At present, disc-type cotton pluckers all use spray humidification to humidify the cotton pile. Specifically, a spray device is installed at the entrance of the cotton plucker or the cotton bale stacking area to evenly spray water mist. However, the water mist can only adhere to the surface of the cotton pile, and the cotton beater will grab a certain thickness of cotton layer when plucking cotton at one time. Therefore, the cotton layer on the surface of the plucking thickness is attached with water mist, while the cotton layer at the bottom of the plucking thickness has no water mist attached. The humidity cannot meet the requirements, which increases the probability of fiber breakage, short fibers and cotton knots, affecting the subsequent processing quality. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a disc-type cotton plucking machine that can adaptively adjust the humidification amount, which at least partially solves the above problem.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a disc-type plucking machine capable of adaptively adjusting the humidification amount, comprising: Cotton storage; A central column is arranged at the center of the cotton pile bin, and a cotton grabbing unit rotating around the cotton pile bin is connected to the central column; Wherein, the central column is connected to a support arm, and the support arm is provided with a driving unit for driving the support arm to intermittently rotate around the cotton pile bin; A support tube is provided below the support arm, a telescopic mechanism for driving the support tube to rise and fall is provided above the support arm, a plurality of vertically arranged inserts are provided on the support tube, the inserts are communicated with the support tube, and a plurality of mist exhaust holes are provided on the inserts; Furthermore, an atomizer is provided on the support arm, and an output end of the atomizer is connected to the support tube through a delivery pipeline.

[0007] Furthermore, the delivery pipeline includes a fixed pipe and a movable pipe, the fixed pipe includes a vertical section, and the movable pipe is slidably connected in the vertical section of the fixed pipe.

[0008] Furthermore, a sealing plug for sealing is provided at the gap between the outer wall of the movable tube and the inner wall of the fixed tube, and the sealing plug is located at the top end of the movable tube.

[0009] Furthermore, a pressure sensor is provided at the bottom end of the cannula for detecting the pressure exerted on the cannula when the cannula is inserted into the cotton.

[0010] Furthermore, a protective cover is connected to the bottom end of the pressure sensor.

[0011] Furthermore, the driving unit includes a driving mechanism, a driving gear and a fixed gear, the driving mechanism is arranged on the support arm, the driving gear is connected to the output shaft of the driving mechanism, the fixed gear is fixed on the center column, and the fixed gear and the center column are coaxially arranged with each other, and the driving gear is engaged with the fixed gear.

[0012] Furthermore, the driving mechanism includes a worm gear reducer and a servo motor, the output shaft of the servo motor is connected to the input shaft of the worm gear reducer, and the driving gear is connected to the output shaft of the worm gear reducer.

[0013] Furthermore, the cotton picking unit includes a trolley, a cotton picking arm and a cotton suction tube. One end of the trolley is rotatably connected to the center column, and the other end of the trolley is provided with a traveling wheel. A cotton picking arm that can be raised and lowered is provided under the trolley, and the cotton picking arm is connected to an external fan through a cotton suction tube.

[0014] Furthermore, a feed port is provided on one side of the cotton stacking bin, and a bin door is hinged on one side of the feed port.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. By setting a rotating support arm and a liftable intubation tube, the atomizer delivers water mist to the intubation tube and discharges it from the mist exhaust hole. As the support arm rotates intermittently, when the support arm stops rotating, the telescopic mechanism is used to push the support tube down, and then the intubation tube is inserted into the raw cotton inside the cotton pile bin to humidify the deep part of the cotton pile. The cotton of the thickness grasped by the cotton grabbing arm is humidified, reducing the probability of fiber breakage, short lint and cotton neps.

[0016] 2. By setting a pressure sensor at the bottom end of the cannula, when the cannula is inserted into the cotton pile, it will be subjected to the reaction force of the cotton pile. The tighter the cotton pile, the greater the reaction force on the cannula. Therefore, the reaction force on the cannula is detected by the pressure sensor to judge the compactness of the cotton pile, and then adjust the pressure of the water mist output by the atomizer and the speed of the beater inside the cotton grabbing arm.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0022] like Figure 1 As shown, the present invention proposes a disc-type cotton plucking machine capable of adaptively adjusting the amount of humidification, comprising a cotton bunker 1, a central column 11 and a cotton plucking unit.

[0023] The cotton stacking bin 1 is configured as a disc-shaped structure, and the central column 11 is configured in the center of the cotton stacking bin 1 (ie, the cotton stacking bin 1 and the central column 11 are coaxial with each other). An annular space is formed between the central column 11 and the cotton stacking bin 1 for stacking raw cotton.

[0024] In a specific embodiment, the cotton picking unit includes a traveling vehicle 12, a cotton picking arm 13 and a cotton suction tube 14. One end of the traveling vehicle 12 is rotatably connected to the central column 11, and the other end of the traveling vehicle 12 extends to the outside of the cotton pile bin 1, and a traveling wheel is provided at the bottom. The traveling wheel includes a roller, a drive motor and a transmission mechanism. The drive motor drives the roller to rotate through the transmission mechanism, and the roller moves along the ground outside the cotton pile bin 1 (or a pre-laid track), thereby driving the traveling vehicle 12 to rotate around the central column 11.

[0025] A cotton grabbing arm 13 is provided under the traveling vehicle 12. The cotton grabbing arm 13 is located in the annular space between the central column 11 and the cotton pile bin 1. The cotton grabbing arm 13 is connected to the external fan through the cotton suction tube 14. The cotton grabbing arm 13 is equipped with a beater and a drive motor. The drive motor drives the beater to rotate at high speed to grab the cotton, which is then transported by the cotton suction tube 14.

[0026] A lift is provided on one side of the traveling vehicle 12, and the cotton grabbing arm 13 is connected to the lift. The lift controls the cotton grabbing arm 13 to rise or fall, so that the cotton grabbing arm 13 can grab cotton layer by layer from top to bottom.

[0027] In an optional embodiment, the elevator includes an electric screw slide, and one end of the cotton grabbing arm 13 is connected to the slider of the electric screw slide. The electric screw slide has a high lifting accuracy and can accurately control the cotton grabbing height of the cotton grabbing arm 13.

[0028] Furthermore, a feed port 101 is provided on one side of the cotton stacking bin 1 , and a bin door 15 is hinged on one side of the feed port 101 . By opening the bin door 15 , raw cotton can be replenished into the cotton stacking bin 1 through the feed port 101 .

[0029] In this way, raw cotton is replenished into the cotton bunker 1 through the feed port 101, the traveling vehicle 12 rotates around the central column 11, the cotton grabbing arm 13 under the traveling vehicle 12 grabs the cotton, and is transported by the cotton suction tube 14, and the cotton grabbing arm 13 is controlled by the elevator to gradually descend so that the cotton grabbing arm 13 can grab the cotton layer by layer from top to bottom.

[0030] Combine Figure 1 、 Figure 2 and Figure 3 As shown, a support arm 2 is connected to the central column 11, and a support tube 21 is provided below the support arm 2. The support tube 21 is located in the annular space between the central column 11 and the cotton pile bin 1. A telescopic mechanism 23 for driving the support tube 21 to rise and fall is provided above the support arm 2. A plurality of vertically arranged insert tubes 22 are provided on the support tube 21, and the insert tubes 22 are connected to the support tube 21. A plurality of mist exhaust holes 221 are provided on the insert tube 22; An atomizer 24 is provided on the support arm 2, and the output end of the atomizer 24 is connected to the support tube 21 through a delivery pipeline. The atomizer 24 can deliver water mist to the support tube 21 through the delivery pipeline, and the water mist in the support tube 21 is dispersed into each insert 22 and discharged from the mist exhaust hole 221. The telescopic mechanism 23 is used to push the support tube 21 down, and then the insert 22 is inserted into the raw cotton inside the cotton pile bin 1 to humidify the deep part of the cotton pile.

[0031] It should be noted that the length of the intubation 22 is consistent with the thickness of the cotton that the cotton grabbing arm 13 grabs at one time. Therefore, after the intubation 22 is fully inserted into the cotton pile, the cotton with the same thickness as the height of the intubation 22 can be humidified, so that all the cotton grabbed by the cotton grabbing arm 13 is humidified.

[0032] The support arm 2 is provided with a driving unit for driving the support arm 2 to intermittently rotate around the cotton pile bin 1. When the cannula 22 is inserted downward into the cotton pile, the support arm 2 does not rotate to prevent the cannula 22 from dragging the cotton pile. After humidification for a certain period of time, the telescopic mechanism 23 drives the support tube 21 and the cannula 22 to rise and separate from the cotton pile. The driving unit drives the support arm 2 to rotate a certain angle, and then the cannula 22 is inserted downward into the cotton pile again to humidify the cotton pile. The above steps are repeated. As the cotton grabbing arm 13 continues to grab cotton, the cannula 22 humidifies the cotton pile layer by layer. At the same time, the angle of rotation of the support arm 2 is adjusted according to the compactness of the cotton pile. When the cotton pile is compact, it is difficult for the water mist to diffuse in the cotton. Therefore, the support arm 2 rotates at a smaller angle to increase the frequency of inserting the cannula 22 into the cotton pile for humidification. When the cotton pile is loose, the water mist is easier to diffuse in the cotton. Therefore, the support arm 2 rotates at a larger angle to reduce the frequency of inserting the cannula 22 into the cotton pile for humidification.

[0033] It should be noted that, by controlling the rotation speed of the support arm 2 driven by the driving unit, the angle between the support arm 2 and the traveling vehicle 12 is made not less than 100°, thereby avoiding interference between the support arm 2 and the traveling vehicle 12 .

[0034] The cotton picking arm 13 is controlled to gradually descend by the elevator so that the cotton picking arm 13 can pick up the cotton layer by layer from top to bottom. While the cotton picking arm 13 rotates to pick up the cotton, the support arm 2 rotates intermittently around the cotton pile bin 1. When the support arm 2 stops rotating, the telescopic mechanism 23 is used to push the support tube 21 down, thereby inserting the insertion tube 22 into the raw cotton inside the cotton pile bin 1 to humidify the deep part of the cotton pile. After humidification for a certain period of time, the telescopic mechanism 23 drives the support tube 21 and the insertion tube 22 to rise and separate from the cotton pile. The driving unit drives the support arm 2 to rotate a certain angle, and then the insertion tube 22 is inserted into the cotton pile again to humidify the cotton pile. Repeat the above steps. As the cotton picking arm 13 continues to pick up the cotton, the insertion tube 22 deeply humidifies the cotton pile layer by layer, so that the cotton of the thickness grabbed by the cotton picking arm 13 is humidified, reducing the probability of fiber breakage, short fibers and cotton neps.

[0035] It should be noted that the atomizer 24 continuously delivers water mist into the cannula 22 and does not intermittently supply water mist with the intermittent movement of the support arm 2. Therefore, when the cannula 22 is inserted downward into the cotton pile, the deep part of the cotton pile is humidified. After rising and separating from the cotton pile, the output water mist falls on the surface of the cotton pile under the action of gravity, humidifying the surface of the cotton pile.

[0036] Combine Figure 3 and Figure 4 As shown, the delivery pipeline includes a fixed pipe 25 and a movable pipe 26. One end of the fixed pipe 25 is connected to the output end of the atomizer 24, and one end of the movable pipe 26 is connected to the support pipe 21. The fixed pipe 25 includes a vertical section, and the movable pipe 26 is slidably connected in the vertical section of the fixed pipe 25. When the support pipe 21 is raised or lowered, the movable pipe 26 slides in the vertical section of the fixed pipe 25 to adapt to the height change of the support pipe 21 and maintain normal delivery of water mist.

[0037] Furthermore, a sealing plug 261 for sealing is provided in the gap between the outer wall of the movable tube 26 and the inner wall of the fixed tube 25. The sealing plug 261 is located at the top end of the movable tube 26. The gap between the outer wall of the movable tube 26 and the inner wall of the fixed tube 25 is sealed by the sealing plug 261 to prevent water mist from leaking through the gap and maintain the delivery pressure of the water mist.

[0038] Combine Figure 1 and Figure 3 As shown, the driving unit includes a driving mechanism 3, a driving gear 31 and a fixed gear 32. The driving mechanism 3 is arranged on the support arm 2. The driving gear 31 is connected to the output shaft of the driving mechanism 3. The fixed gear 32 is fixed on the center column 11. The fixed gear 32 and the center column 11 are coaxially arranged with each other, and the driving gear 31 is engaged with the fixed gear 32.

[0039] The driving mechanism 3 drives the driving gear 31 to operate. Since the fixed gear 32 is fixedly set on the central column 11, the driving gear 31 can move along the fixed gear 32 and rotate around the central column 11, thereby driving the support arm 2 to rotate around the central column 11.

[0040] It should be noted that the drive mechanism 3 is connected to the external control unit signal, and according to the preset control logic, the action of the drive mechanism 3 is controlled to realize intermittent operation of the drive mechanism 3, and the shutdown interval time and operating speed of the drive mechanism 3 are set by the external control unit to meet actual usage requirements.

[0041] In a specific embodiment, the driving mechanism 3 includes a worm gear reducer and a servo motor. The output shaft of the servo motor is connected to the input shaft of the worm gear reducer, and the driving gear 31 is connected to the output shaft of the worm gear reducer. The servo motor can stably drive the support arm 2 to operate after deceleration and torque increase through the worm gear reducer, and the speed of the servo motor can be adjusted.

[0042] Combine Figure 5 As shown, a pressure sensor 27 is provided at the bottom end of the insert tube 22. When the insert tube 22 is inserted into the cotton pile, it will be subjected to a reaction force from the cotton pile. The tighter the cotton pile is, the greater the reaction force the insert tube 22 is subjected to. Correspondingly, the looser the cotton pile is, the smaller the reaction force the insert tube 22 is subjected to. Therefore, the reaction force applied to the insert tube 22 is detected by the pressure sensor 27 to determine the compactness of the cotton pile.

[0043] In this way, when the cotton pile is relatively compact, the atomizer 24 is controlled to increase the pressure of the output water mist so that the water mist can better penetrate the cotton pile. When the cotton pile is relatively loose, the atomizer 24 is controlled to reduce the pressure of the output water mist to reduce energy consumption. According to the value detected by the pressure sensor 27, the pressure of the water mist output by the atomizer 24 is adaptively adjusted.

[0044] Accordingly, the cotton grabbing arm 13 can adjust the beater rotation speed according to the compactness of the cotton pile measured by the pressure sensor 27, so that the cotton grabbing arm 13 can grab the cotton smoothly and avoid the phenomenon of insufficient cotton grabbing force.

[0045] Furthermore, the bottom end of the pressure sensor 27 is connected to a protective cover 28 , which is configured as a conical structure. While protecting the pressure sensor 27 , the conical structure can guide the cannula 22 to be smoothly inserted into the cotton pile.

[0046] The working principle of the present invention is as follows: raw cotton is added to the cotton bunker 1 through the feed port 101, the traveling vehicle 12 rotates around the central column 11, the cotton grabbing arm 13 below the traveling vehicle 12 grabs the cotton and is transported by the cotton suction pipe 14. The cotton grabbing arm 13 is gradually lowered by the elevator so that the cotton grabbing arm 13 can grab the cotton layer by layer from top to bottom; When the cotton grabbing arm 13 rotates to grab the cotton, the driving mechanism 3 drives the active gear 31 to operate, and the active gear 31 moves along the fixed gear 32 and rotates around the central column 11, thereby driving the support arm 2 to rotate around the central column 11. The external control unit controls the action of the driving mechanism 3 according to the preset control logic, so that the driving mechanism 3 operates intermittently, thereby causing the support arm 2 to rotate intermittently around the cotton pile bin 1. When the support arm 2 stops rotating, the telescopic mechanism 23 is used to push the support tube 21 down, thereby inserting the insertion tube 22 into the raw cotton inside the cotton pile bin 1. The cotton pile is humidified deep inside. After humidification for a certain period of time, the telescopic mechanism 23 drives the support tube 21 and the insert tube 22 to rise and separate from the cotton pile. The driving unit drives the support arm 2 to rotate a certain angle, and then the insert tube 22 is inserted downward into the cotton pile again to humidify the cotton pile. The above steps are repeated. As the cotton grabbing arm 13 continues to grab the cotton, the height of the cotton pile decreases. Accordingly, the height of the insert tube 22 gradually decreases, so that the insert tube 22 deeply humidifies the cotton pile layer by layer, so that the cotton of the thickness grabbed by the cotton grabbing arm 13 is humidified, reducing the probability of fiber breakage, short lint and cotton neps. At the same time, the angle of the support arm 2's single rotation is adjusted according to the compactness of the cotton pile. When the cotton pile is compact, the mist is difficult to diffuse within the cotton. Therefore, the support arm 2 rotates at a smaller angle to increase the frequency of inserting the cannula 22 into the cotton pile for humidification. When the cotton pile is loose, the mist is easier to diffuse within the cotton. Therefore, the support arm 2 rotates at a larger angle to reduce the frequency of inserting the cannula 22 into the cotton pile for humidification.

[0047] When the cannula 22 is inserted into the cotton pile, it will be subjected to the reaction force of the cotton pile. The pressure sensor 27 detects the reaction force exerted on the cannula 22 and determines the compactness of the cotton pile. When the cotton pile is relatively compact, the atomizer 24 is controlled to increase the pressure of the output water mist so that the water mist can better penetrate the cotton pile. When the cotton pile is relatively loose, the atomizer 24 is controlled to reduce the pressure of the output water mist, thereby reducing energy consumption. Accordingly, the cotton grabbing arm 13 can adjust the speed of the beater according to the compactness of the cotton pile measured by the pressure sensor 27, so that the cotton grabbing arm 13 can smoothly grab the cotton and avoid the phenomenon of insufficient cotton grabbing force.

[0048] In summary of the above embodiments: by providing a support arm 2 that rotates around the central column 11, and providing a liftable intubation tube 22 on the support arm 2, the atomizer 24 can deliver water mist to the intubation tube 22 through the delivery pipeline, and discharge it from the mist discharge hole 221. As the support arm 2 rotates intermittently, when the support arm 2 stops rotating, the telescopic mechanism 23 is used to push the support tube 21 down, and then the intubation tube 22 is inserted into the raw cotton inside the cotton pile bin 1, humidifying the deep part of the cotton pile, so that the cotton of the thickness grasped by the cotton grabbing arm 13 is humidified, reducing the probability of fiber breakage, generating short lint and cotton neps; According to the compactness of the cotton pile, the angle of the support arm 2 is adjusted. When the cotton pile is compact, the water mist is difficult to diffuse in the cotton. Therefore, the support arm 2 is rotated at a smaller angle to increase the frequency of inserting the cannula 22 into the cotton pile for humidification. When the cotton pile is loose, the water mist is easier to diffuse in the cotton. Therefore, the support arm 2 is rotated at a larger angle to reduce the frequency of inserting the cannula 22 into the cotton pile for humidification. By providing a pressure sensor 27 at the bottom end of the insert tube 22, when the insert tube 22 is inserted into the cotton pile, it will be subjected to a reaction force from the cotton pile. The tighter the cotton pile, the greater the reaction force on the insert tube 22. Correspondingly, the looser the cotton pile, the smaller the reaction force on the insert tube 22. Therefore, the reaction force on the insert tube 22 is detected by the pressure sensor 27 to judge the compactness of the cotton pile, and then adjust the pressure of the water mist output by the atomizer 24 and the beater speed inside the cotton grabbing arm 13.
