Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides an adjustable cotton feeding device for a combing machine, including a bracket 1. Connecting arms 2 are hinged to both sides of the bracket 1 via hinge joints. An mounting plate 3 is integrally fixed to the end of each connecting arm 2. The bracket 1 is also equipped with two telescopic cylinders 4 corresponding to the connecting arms 2. One end of the piston rod of each telescopic cylinder 4 is hinged to the bracket 1, and the other end is hinged to the connecting arm 2. Positioning sleeves 5 are mounted on both mounting plates 3 via bearings. A roller 6 is installed between the two positioning sleeves 5, and the roller 6 has roller teeth 7. The mounting plate 3 on one side is equipped with a drive mechanism that drives the positioning sleeve 5 to rotate. In use, the whole unit is installed inside the cover, which has an inlet and outlet. The drive mechanism drives the roller 6 and roller teeth 7 to rotate, so that the cotton web is input from the inlet. The roller 6 and roller teeth 7 roll up the cotton web that enters the cover and then output it through the outlet. During adjustment, the piston rods of the telescopic cylinders 4 on both sides extend and retract, thereby driving the connecting arm 2 to swing, which in turn drives the mounting plate 3 and roller 6 to swing, adjusting the height of the roller 6 so that the amount of cotton web that can be rolled up can be controlled.

[0024] Specifically, the positioning sleeve 5 is closed at one end away from the roller 6, and the other end is equipped with a cover 8. The positioning sleeve 5 and the cover 8 enclose an installation groove 9. The roller 6 is provided with installation shafts 10 at both ends corresponding to the installation groove 9. In this embodiment, the roller 6 can be directly disassembled after removing the covers 8 on both sides, which is convenient for assembly and disassembly.

[0025] Specifically, the mounting groove 9 is provided with a limiting groove 11, and the mounting shaft 10 is provided with a limiting protrusion 12 corresponding to the limiting groove 11. In this embodiment, after the mounting shaft 10 of the roller 6 is installed in the mounting groove 9, the limiting groove 11 and the limiting protrusion 12 cooperate to prevent the roller 6 and the positioning sleeve 5 from rotating relative to each other.

[0026] Specifically, the cover 8 and the positioning sleeve 5 are provided with mounting parts. The bottom of the mounting part of the cover 8 is provided with a connecting part 13. The top surface of the mounting part of the positioning sleeve 5 is provided with a connecting groove corresponding to the connecting part 13. The connecting part 13 and the connecting groove are locked by a locking mechanism. In this embodiment, the stability during operation is enhanced by inserting the connecting part 13 into the connecting groove and locking it by the locking mechanism.

[0027] Specifically, the locking mechanism includes an inner groove on the side of the connecting part 13, a compression spring 14 and a positioning block 15 are provided in the inner groove, and an outer groove corresponding to the inner groove is provided in the connecting groove, with the positioning block 15 partially abutting in the outer groove. In this embodiment, during installation, the mounting shaft 10 of the roller 6 can be placed into the mounting groove 9 first, and the limiting protrusion 12 can be aligned with the limiting groove 11. Then, the compression spring 14 and the positioning block 15 are installed in the inner groove of the connecting part 13 of the cover 8, and the positioning block 15 is squeezed into the inner groove. Then, the cover 8 is installed. After it is in place, the positioning block 15 can be locked in the small hole 16 under the compression of the compression spring 14, which enhances the stability during operation.

[0028] Specifically, the mounting part of the positioning sleeve 5 is provided with a small hole 16 for connecting the outer groove; in this embodiment, the positioning block 15 can be pushed back into the inner groove by inserting an external rod into the small hole 16, thereby realizing the removal of the cover 8. After removing the covers 8 on both sides, the roller 6 can be removed directly.

[0029] Specifically, the driving mechanism includes a motor 17 mounted on the mounting plate 3 via a mounting bracket, and a connecting shaft 18 integrally provided at the center of the side of the positioning sleeve 5. The output shaft of the motor 17 is connected to the connecting shaft 18 via a coupling. In this embodiment, when the motor 17 is started, the output shaft of the motor 17 drives the connecting shaft 18 to rotate, which in turn drives the roller 6 and the roller teeth 7 to rotate.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] Working principle: During use, the entire unit is housed within a casing with inlet and outlet. Starting motor 17 drives roller 6 and roller teeth 7 to rotate, feeding the cotton web through the inlet. Roller 6 and roller teeth 7 then wind the cotton web into the casing and discharge it through the outlet. For adjustment, the piston rods of the telescopic cylinders 4 on both sides extend and retract, causing the connecting arm 2 to swing, which in turn causes the mounting plate 3 and roller 6 to swing, adjusting the height of roller 6 to control the amount of cotton web that can be wound. The motor 17 is mounted on the mounting plate 3 with screws, facilitating assembly and disassembly. Simultaneously, external rods are inserted... The small hole 16 pushes the positioning block 15 back into the inner groove, which can realize the disassembly of the cover 8. After disassembling the covers 8 on both sides, the roller 6 can be directly disassembled. Similarly, during installation, the mounting shaft 10 of the roller 6 can be placed into the mounting groove 9 first, and the limiting protrusion 12 can be aligned with the limiting groove 11. Then, the compression spring 14 and the positioning block 15 are installed in the inner groove of the connecting part 13 of the cover 8, and the positioning block 15 is squeezed into the inner groove. Then, the cover 8 is installed. After it is in place, the positioning block 15 can be locked in the small hole 16 under the compression of the compression spring 14. Then, the connecting shaft 18 is driven to rotate by the motor 17, which in turn drives the positioning sleeve 5 and the roller 6 to rotate.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
