Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to an anti-winding beater mechanism and a cotton grabbing production line. Background Art

[0002] A cotton plucker is a machine that grabs cotton fibers from a cotton bale and then conveys the grabbed cotton bale to the next process through a negative pressure air flow pipe. Existing cotton pluckers are mainly divided into two categories: disc type and reciprocating type.

[0003] For example, the Chinese patent publication number is: CN110284219B, and the name of the patent is "A disc-type cotton plucking machine and its cotton plucking process". The patent includes "an outer circular wall panel and an inner circular wall panel, an annular silo is formed between the outer circular wall panel and the inner circular wall panel, and a plurality of driving wheels are evenly arranged in the silo along its circumferential direction, and the two ends of the driving wheels are respectively connected to the inner circular wall panel and the outer circular wall panel through bearings; a plurality of the driving wheels are provided with driving sprockets, and a plurality of the driving sprockets are installed with chains, a driving motor is connected to the side of the outer circular wall panel close to the inner circular wall panel, and an active sprocket meshing with the chain is connected to the driving motor; a conveyor belt is wound on the driving wheel, and the conveyor belt is arranged in a ring shape, and the cotton raw materials can be quickly conveyed to the silo through the conveyor belt, thereby increasing the loading speed and thus improving the production efficiency".

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1-5 An anti-entanglement beater mechanism provided in an embodiment of the present invention includes an annular silo and a cotton grabbing vehicle frame 2 rotating along the annular silo, a cotton opening roller mechanism 3 is rotatably arranged on the cotton grabbing vehicle frame 2, the cotton opening roller mechanism 3 includes an air roller assembly 4, and the air roller assembly 4 is provided with a plurality of roller pricking units 5 for grabbing cotton, and the airflow emitted by the air roller assembly 4 can assist the cotton strips grabbed by the cotton opening roller mechanism 3 to further quickly detach.

[0028] Specifically, the cotton plucking car frame 2 is a rectangular frame structure, the frame opening surface of the cotton plucking car frame 2 is parallel to the annular surface of the annular silo, and the cotton plucking car frame 2 can move along the annular track of the annular silo, and the air roller assembly 4 can be selected as a hollow cylinder, and the centers of both ends of the hollow cylinder are fixedly connected with hard tubes, which are respectively a first end tube and a second end tube, and the first end tube is rotatably connected to the air flow outlet pipe of the blower, and the second end tube is fixed to the motor output shaft fixed on the cotton plucking car frame 2, so that the hollow cylinder can rotate circumferentially on the cotton plucking car frame 2, and the roller pricking unit 5 is a plurality of protruding nails fixed on the circumference of the hollow cylinder, and a plurality of exhaust ports that can blow toward the roller pricking unit 5 are opened on the hollow cylinder;

[0029] During actual use, the motor provides driving force for the rotation of the hollow cylinder, so that the protruding nails can grab the cotton during movement. At the same time, the airflow blown into the hollow cylinder by the blower is blown to the roller through the exhaust port, which is conducive to the separation of the grabbed cotton from the hollow cylinder and the roller, and is conducive to reducing the situation where the cotton is entangled on the hollow cylinder after being pulled, and is also convenient for the cotton to be sucked into the conveying pipeline by negative pressure. In short, the cotton is grabbed by the roller unit on the cotton opening roller mechanism, and the airflow generated by the air roller assembly helps to separate the grabbed cotton from the cotton opening roller mechanism, which is conducive to avoiding the situation where the cotton fibers are not separated from the protrusions in time and are entangled on the roller body, and prevents the problem of the beater being entangled by the cotton, thereby ensuring the normal cotton grabbing work.

[0030] In another embodiment provided by the present invention, the air roller assembly 4 includes a hollow column 4.1, and an air guide tube 4.2 is fixedly passed through the end of the hollow column 4.1. The air guide tube 4.2 is a hard tube, and the center line of the air guide tube 4.2 coincides with the center line of the hollow column 4.1. One end of the air guide tube 4.2 is rotatably mounted on the cotton picking vehicle frame 2 through the air supply unit 4.3, and the other end of the air guide tube 4.2 is rotatably mounted on the cotton picking vehicle frame 2 through the power source mechanism 4.4. A plurality of air flow openings 7 are provided on the hollow column 4.1, so that in actual use, the air guide tube 4.2 can receive the torsional driving force of the power source mechanism 4.4 and rotate, thereby making the hollow column 4.1 rotate synchronously with the air guide tube 4.2 axially. It should be further explained that the bottom of the hollow column 4.1 can extend out of the cotton picking vehicle frame 2.

[0031] In another embodiment provided by the present invention, a plurality of air leakage units 4.21 are provided on the air duct 4.2, each of which is located in the internal space of the hollow column 4.1. Each air leakage unit 4.21 allows the airflow of the air duct 4.2 to enter the cavity of the hollow column 4.1. The airflow of the air duct 4.2 is provided by the air supply unit 4.3, so that the interior of the hollow column 4.1 is filled with gas.

[0032] In another embodiment provided by the present invention, the air leakage port unit 4.21 includes a plurality of openings 4.211 annularly distributed in the circumferential direction of the air guide tube 4.2, each opening 4.211 forms an annular opening band on the air guide tube 4.2, and a sealing sleeve 4.212 capable of covering each opening 4.211 is movably sleeved on the air guide tube 4.2, that is, the sealing sleeve 4.212 can cover the annular opening band, and a venting port 4.213 is provided on the sealing sleeve 4.212, the diameter of the venting port 4.213 is larger than the diameter of the opening 4.211, the venting port 4.213 can be aligned with the corresponding opening 4.211, and the end of the sealing sleeve 4.212 away from the venting port 4.213 is fixedly connected with a starter The weight unit 4.214 finally points downward. In actual use, under the action of gravity of the weight unit 4.214, the vent 4.213 on the sealing sleeve 4.212 is always facing the same direction. Therefore, when the through port 4.211 on the air guide tube 4.2 moves to be aligned with the vent 4.213, the through port 4.211 can quickly release the airflow in the air guide tube 4.2 through the vent 4.213, thereby realizing the directional exhaust of the air leakage port unit 4.21 inside the hollow column 4.1, so that the local gas inflow pressure in the hollow column 4.1 is higher, and the airflow discharged from the air outlet 7 located in this area is stronger, which is conducive to the separation of the cotton located in the area of ​​the air outlet 7.

[0033] In another embodiment of the present invention, bearing rings 4.215 are fixed at both ends of the blocking sleeve 4.212, and the inner ring surface of the bearing ring 4.215 is fixed to the outside of the air guide tube 4.2, so as to reduce the resistance when the blocking sleeve 4.212 and the air guide tube 4.2 rotate relative to each other, and to prevent the heavy hammer unit 4.214 from circumferentially moving along with the air guide tube 4.2. It should be particularly noted that when the air guide tube 4.2 rotates at a high speed, the bearing ring 4.215 still has a little rotation resistance when rotating, so that the heavy hammer unit 4.214 can rotate relative to the air guide tube 4.2. The old will swing within a certain small range, for example, when the swing range is 10 degrees, so that the air vent 4.213 is also in a dynamic swing state within a certain range, so that the air pressure in this area is in a swinging dynamic inflow state, and the airflow discharged from the air flow port 7 has the effect of switching between strong and weak, while increasing the action surface of the airflow ejected from the air vent 4.213, further improving the effect of cotton separation. In addition, the weight unit 4.214 is in the hollow column 4.1, so that the center of gravity of the air roller assembly 4 as a whole is lower, thereby further improving the stability of the air roller assembly 4 during operation.

[0034] In another embodiment provided by the present invention, the weight unit 4.214 includes a counterweight block 4.216, on which a connecting rod 4.217 is fixed, and a plurality of mounting holes 4.218 connected and adapted to the ends of the connecting rod 4.217 are provided on the outer surface of the sealing sleeve 4.212, wherein the axial line of the connecting rod 4.217 can coincide with the radial line of the sealing sleeve 4.212, the counterweight block 4.216 is preferably a conical block, and the plurality of mounting holes 4.218 are evenly distributed in a ring shape on the outer surface of the sealing sleeve 4.212, and the mounting holes 4.218 can be threaded holes, and one end of the connecting rod 4.217 that can be plugged into the threaded hole is provided with a thread tooth adapted to the threaded hole, and in actual use, by changing the connecting rod 4.217 to connect with the threaded holes at different positions on the outer surface of the sealing sleeve 4.212, the direction of the vent 4.213 can be changed, so as to facilitate adjustment according to actual conditions.

[0035] In another embodiment provided by the present invention, the air supply unit 4.3 includes a blower 4.31 fixed to the cotton plucking car frame 2, both ends of a drive shaft 4.32 of the blower 4.31 extend out of both sides of the blower 4.31, the drive shaft 4.32 is a pipe column structure, one end of the drive shaft 4.32 is fixed to one end of the air duct 4.2, and the other end of the drive shaft 4.32 is rotatably connected to an air supply pipe 4.33, and the other end of the air supply pipe 4.33 is connected to an air outlet end of the blower 4.31. In actual use, the air supply pipe 4.2 receives the power source mechanism 4.4 to rotate axially, and at the same time, the air supply pipe 4.2 also drives the turbofan of the blower 4.31 to rotate, and then the airflow generated by the blower 4.31 is transmitted to the air supply pipe 4.2 through the air supply pipe 4.33, thereby providing an air source for the air supply pipe 4.2.

[0036] In another embodiment provided by the present invention, an isolation cover 2.1 is connected to a fixed cover on the cotton plucking car frame 2, and an isolation plate 2.2 is provided between the isolation cover 2.1 and the cotton plucking car frame 2, thereby forming an isolation space capable of isolating the blower 4.31, and an air vent 2.3 connected to the outside is provided on the plate body of the isolation plate 2.2, so that outside air can enter the isolation space, and a filter screen 2.4 is fixed on the air vent 2.3, so as to prevent the blower 4.31 from causing cotton fibers to enter with the air when exhausting air. In the blower 4.31, a cleaning brush 2.5 fixed to the air duct 4.2 is provided on one side of the filter 2.4. The cleaning brush 2.5 can remove the cotton attached to the filter 2.4 when in motion. In actual use, when the air duct 4.2 rotates, the cleaning brush 2.5 rotates synchronously with the air duct 4.2. The cleaning brush 2.5 can contact the filter 2.4 during the movement, thereby removing the cotton on the filter 2.4 and keeping the air flow of the vent 2.3 unobstructed.

[0037] It should be further explained that a plurality of ventilation holes 8 are provided on the brush plate of the cleaning brush 2.5, and a plurality of fan blades 9 distributed in a ring are fixed to the end of the hollow column 4.1. In actual use, the airflow generated by the fan blades 9 when in motion can pass through the ventilation holes 8, so that the cotton on the cleaning brush 2.5 is separated from the bristles, and then enters the feed pipeline along with the negative pressure airflow of the isolation cover 2.1, thereby achieving a self-cleaning effect on the cleaning brush 2.5.

[0038] In another embodiment provided by the present invention, the power source mechanism 4.4 includes a driving motor 4.41 whose output shaft is fixed to the end of the air duct 4.2. A support hinge 4.42 for rotatably supporting the air duct 4.2 on the cotton picking vehicle frame 2 is provided on one side of the driving motor 4.41. The support hinge 4.42 can maintain the support for the air duct 4.2 without affecting the normal axial operation of the air duct 4.2. The axis line of the air duct 4.2 and the axis line of the driving motor 4.41 are on the same straight line. In actual use, the driving motor 4.41 drives the air duct 4.2 to rotate axially when rotating, thereby providing driving force for the axial rotation of the air duct 4.2.

[0039] In another embodiment provided by the present invention, the roller pricking unit 5 can be selected as a plurality of pricking rods that are movable and pass through the air flow opening 7, one end of the pricking rod extends out of the hollow column 4.1, and the other end of the pricking rod is connected to the air guide tube 4.2 through a connecting piece 6. Preferably, the air flow opening 7 is a circular opening, and the diameter value of the pricking rod is smaller than the diameter value of the pricking rod. When the air flow in the hollow column 4.1 is discharged through the air flow opening 7, the air flow flows along the length direction of the pricking rod, which is conducive to the separation of cotton from the pricking rod and prevents entanglement on the hollow column 4.1.

[0040] In another embodiment provided by the present invention, the connecting member 6 includes a sleeve ring 10 fixedly sleeved with the air guide tube 4.2, and a hinge seat 11 movably connected to the end of the thorn rod is fixedly installed on the circumference of the sleeve ring 10, and an arc cavity 12 is opened on the same side wall of each air flow opening 7, and an arc plate 13 fixed to the thorn rod is adapted and inserted inside the arc cavity 12, and a scraper 14 capable of sliding with the inner wall of the arc cavity 12 is fixed to one end of the arc plate 13 located in the arc cavity 12, and the arc plate 13 can cover the air flow opening 7 when extended. It should be further explained that the center of the arc structure of the cavity of the arc cavity 12 is on the center line of the air guide tube 4.2;

[0041] In actual use, when the air guide tube 4.2 is in a high-speed rotation state, the thorn rod is at one side that can be close to the side of the air flow port 7 where the arc cavity 12 is opened, and the air flow port 7 is in a maximum opening state. At this time, the thorn rod is in a centrifugal position. When the thorn rod contacts the cotton on the cotton block, the thorn rod is deviated in the air flow port 7 under the resistance of the cotton, so that the thorn rod approaches the side of the air flow port 7 away from the arc cavity 12, and the arc plate 13 is withdrawn from the arc cavity 12 to cover the air flow port 7, thereby facilitating the reduction of the hollow column 4.1. The airflow in the air flows outward through the air flow outlet 7 at the position, which is helpful to avoid interference when the thorn rod grabs the cotton. In addition, when the arc plate 13 is pulled out of the arc cavity 12, the scraper 14 moves quickly in the arc cavity 12 to form a negative pressure resistance in the arc cavity 12, thereby buffering the deviation of the thorn rod in the air flow outlet 7. When the thorn rod moves away from the cotton and the dough block, the centrifugal force causes the thorn rod to return to the centrifugal position. At the same time, the cotton block on the thorn rod is completely separated from the thorn rod under the centrifugal force of the cotton block itself and the air flow of the air flow outlet 7.

[0042] In another embodiment provided by the present invention, the center of gravity of the thorn rod is located at one end of the thorn rod extending out of the hollow column 4.1, so as to facilitate the thorn rod to return to the centrifugal position as soon as possible when performing centrifugal movement. Preferably, a hollow cavity 15 is provided inside the thorn rod, and the extended end of the thorn rod is a solid end body. Furthermore, a plurality of guide grooves 16 are provided outside the thorn rod, and the length direction of each guide groove 16 is parallel to the length direction of the thorn rod.

[0043] The present invention also provides a cotton plucking production line, on which the above-mentioned anti-winding beater mechanism is arranged.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
