Technical Field

[0001] The utility model relates to the technical field of cotton plucking machines, in particular to an adjustable cotton plucking machine device for spinning. Background Art

[0002] The plucker is usually placed at the top of the combined machine. There are upper grabbing type, lower grabbing type, trolley reciprocating type, trolley (or cotton bale table) rotary type, trolley lifting type, platform lifting type, etc. Generally, blades (or saw blades) beaters and ribs are used, and there are also angle nails or spring clamps to grab fibers from the surface of the cotton bale, and then transport them to the subsequent machine for further processing by air flow or mechanical means. Its structure is constantly being improved. For example, the upper grabbing type is adopted to achieve multi-bale (40 to 80 bales) cotton mixing; the installation of automatic control devices such as quantitative grabbing facilitates the change of mixing ratio and improves the accuracy of the mixing ratio.

[0003] During the cotton plucking operation, the cotton plucking machine needs to make a circular motion to comb the cotton raw materials evenly and transport the cotton raw materials through the conveying pipe at the same time. At this time, it is particularly important to comb the cotton raw materials evenly. However, the existing cotton plucking machines often cannot adjust the height of their own cotton plucking rollers. Therefore, during the operation, the combing effect cannot be freely adjusted, which is inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , the utility model provides a technical solution: an adjustable cotton plucking machine device for spinning, comprising a main device frame 1 with an open bottom end;

[0020] The bottom of the front end and the rear end of the main device frame 1 are both transversely penetrated with mounting grooves 2, and the insides of the two mounting grooves 2 are vertically slidably connected with sliding blocks 3, and a cotton grabbing roller 4 is transversely rotatably connected between the two sliding blocks 3. The front end and the rear end surfaces of the main device frame 1 are both fixedly connected with vertically arranged electric control telescopic rods 5, and the bottom ends of the telescopic rods of the two electric control telescopic rods 5 are respectively fixedly connected to the upper surfaces of the two sliding blocks 3;

[0021] A motor box 11 is fixedly connected to the upper surface of the front end of the main device frame 1, a motor 12 is fixedly connected to the inside of the motor box 11, a driving pulley 13 is fixedly connected to the front end of the output shaft of the motor 12, a driven pulley 7 is fixedly connected to the front end of the outer surface of the cotton picking roller 4, a through groove 14 is vertically penetrated through the upper surface of the main device frame 1 and located below the driving pulley 13, and the driving pulley 13 and the driven pulley 7 are connected by belt transmission.

[0022] The cotton picking roller 4 of the device is driven to rotate by the motor 12. When the motor 12 is running, the rotation of its output shaft can drive the driven pulley 7 to rotate through the active pulley 13 on the surface of the output shaft, thereby driving the cotton picking roller 4 fixedly connected to the driven pulley to rotate.

[0023] When the height of the cotton picking roller 4 needs to be adjusted, the two electrically-controlled telescopic rods 5 can be synchronously controlled to extend or shorten. When they are extended, the two sliding blocks 3 can be driven to move downward, thereby driving the cotton picking roller 4 to move downward. When the two electrically-controlled telescopic rods 5 are shortened, the two sliding blocks 3 will move upward, thereby driving the cotton picking roller 4 to move upward.

[0024] The top ends of the two sliding blocks 3 are each provided with a guide hole extending vertically therethrough, and the insides of the two guide holes are each vertically slidably connected with a guide rod 6 , and the two guide rods 6 are respectively vertically fixedly connected to the insides of the two mounting grooves 2 .

[0025] The guide rod 6 plays a guiding role, ensuring that the two sliding blocks 3 can slide vertically stably without deviation, thereby ensuring that the cotton grabbing roller 4 can move up or down stably.

[0026] The front end surface of the main device frame 1 is laterally penetrated with two slide grooves 8 arranged along its width direction. The two slide grooves 8 are symmetrical with each other with the center line of the main device frame 1 as the central axis. The insides of the two slide grooves 8 are slidably connected to sliding seats 9. The inner ends of the two sliding seats 9 are laterally rotatably connected to fastening wheels 10. The two fastening wheels 10 are located between the belts.

[0027] When the cotton picking roller 4 moves up or down, the distance between the driving pulley 13 and the driven pulley 7 will change, causing the tightness of the belt to change. In order to ensure tight transmission between the pulleys, it is necessary to control the two fastening wheels 10 to move outward or inward to ensure the tightness of the belt.

[0028] A servo motor 15 is laterally fixedly connected to one side of the front end surface of the main device frame 1, and a bidirectional threaded rod 16 is laterally fixedly connected to the outer end of the output shaft of the servo motor 15. Both ends of the bidirectional threaded rod 16 are threadedly connected to threaded sleeves 17, and the two threaded sleeves 17 are respectively fixedly connected to the front ends of the two sliding seats 9.

[0029] When it is necessary to adjust the movement of the two fastening wheels 10, the servo motor 15 can be started. When the servo motor 15 is started, the output shaft thereof can drive the bidirectional threaded rod 16 to rotate. During the rotation of the bidirectional threaded rod 16, the threaded sleeves 17 at both ends thereof will respectively move in opposite directions, thereby driving the two sliding seats 9 and the supporting fastening wheels 10 at the inner ends of the two sliding seats 9 to move synchronously, thereby supporting the belt and ensuring the tightness of the belt.

[0030] A plurality of support rings are laterally fixedly connected to the front end surface of the main device frame 1, and a bidirectional threaded rod 16 is laterally rotatably connected to the inside of the plurality of support rings.

[0031] The support ring supports the bidirectional threaded rod 16 to ensure that the horizontal state of the bidirectional threaded rod 16 does not change.

[0032] The bottom end of the main device frame 1 is laterally fixedly connected with a plurality of blocking bars 18 at even intervals along the length direction thereof.

[0033] The baffle 18 is an existing structure of the plucking machine, which prevents too much cotton material from entering the inside of the plucking machine.

[0034] When the device is in operation, the height of the cotton picking roller 4 of the device can be adjusted through its own structure. During adjustment, the two sliding blocks 3 can be driven to move vertically synchronously by controlling the two electrically-controlled telescopic rods 5 to extend or shorten synchronously. The cotton picking roller 4 located between the two sliding blocks 3 can also move synchronously in the height direction, so as to adjust the combing effect of the cotton picking operation of the device, thereby improving the cotton picking and combing ability of the device.
