Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cotton gins and relates to a cotton gin which is convenient for adjusting the gap between cotton seed channels. Background Art
[0002] In the prior art, when the cotton gin is unpacked, the cotton feeding roller will move away from the saw blade, increasing the gap between the cotton feeding roller and the saw blade. At this time, the cotton feeding roller will still transport the cotton under the drive of the motor. In order to prevent the cotton from falling through the increased gap, Figure 1 As shown, a barrier rib is installed between the feed roller and the ribs to prevent cotton from falling. During operation, the cotton gin's saw blade extends through the barrier rib, hooking the cotton. Cotton seeds then fall through the seed channel between the rib and the barrier rib. However, because the barrier rib extends upward from the feed roller, the saw blade cannot hook the cotton seeds smoothly, resulting in a small amount of cotton seeds entering the lap box. Furthermore, the presence of the barrier rib reduces the gap in the seed channel, making the cotton seeds fall less smoothly, thus reducing production capacity. Utility Model Content
[0003] In order to solve the above deficiencies in the prior art, the present invention aims to provide a cotton gin that is easy to adjust the gap between the cotton seed gins, so as to improve the smoothness of the cotton seed falling and increase the production capacity.
[0004] In order to achieve the above purpose, the technical solutions adopted by this utility model are as follows:
[0005] A cotton gin that is convenient for adjusting the gap between cotton seed paths comprises a cotton gin body, the cotton gin body comprising a frame, a cotton feeding roller rotatably arranged on the frame, and a saw blade rotatably arranged on the frame, the frame being rotatably connected to a rotating shaft, an adjusting plate being fixedly provided on the rotating shaft, the adjusting plate being located below the cotton feeding roller, and one side of the adjusting plate extending toward the edge of the saw blade to form a gap between the adjusting plate and the edge of the saw blade, a positioning device being fixedly provided on the rotating shaft for controlling the tangent angle between the adjusting plate and the saw blade.
[0006] As a limitation of the present invention, the cotton feeding roller is driven by a brake motor.
[0007] As another limitation of the present invention, the positioning device includes a handle hinged on the rotating shaft and a positioning plate fixed on the frame, the positioning plate is provided with a plurality of grooves for changing the rotation angle of the rotating shaft, and the handle is clamped on any one of the grooves of the positioning plate.
[0008] As a limitation of the present invention, the positioning plate is in the shape of an arc with the rotating shaft as the center.
[0009] As a further limitation of the present invention, a positioning ball is fixedly provided on the handle, and after the handle is clamped in the groove of the positioning plate, the positioning ball abuts against the positioning plate.
[0010] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0011] (1) The utility model removes the original upward-extending barrier ribs, greatly increasing the space of the cotton seed channel. At the same time, the downward-extending adjustment plate is added to block the cotton and prevent the cotton from falling without being hooked when the box is opened. Moreover, since the adjustment plate extends downward, it does not affect the efficiency of the saw blade in hooking the cotton. It can increase the space of the cotton seed channel and improve the smoothness of the cotton seeds falling, and can also increase the amount of seed cotton entering the cotton roll box, thereby increasing production capacity.
[0012] (2) The utility model utilizes a brake motor to drive the cotton feeding roller to rotate. When the box is opened, the brake motor stops rotating, and the cotton feeding roller and the motor shaft are instantly locked, preventing the cotton from being fed further, and further preventing the cotton from falling with the cotton seeds without being hooked;
[0013] (3) The positioning structure of the utility model is simple, and the angle of the adjustment plate can be adjusted according to the quality and type of cotton, thereby increasing or decreasing the gap between the adjustment plate and the edge of the saw blade, which makes it more practical;
[0014] (4) The positioning plate of the present invention is in an arc shape, which ensures that the handle is fixed in position and engages with the groove. In addition, the positioning ball is provided so that the positioning ball and the positioning plate can be abutted against each other, thereby improving the firmness of the positioning.
[0015] In summary, the cotton seeds of the utility model fall smoothly, have high production efficiency, and are suitable for cotton ginning machines. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.
[0023] Embodiment A cotton ginning machine for conveniently adjusting the gap between cotton seed channels
[0024] like Figure 2 As shown, this embodiment includes a cotton gin body, which includes a frame 2, a cotton feeding roller 3 rotatably mounted on the frame 2, and a saw blade 4 rotatably mounted on the frame 2. The above is the prior art and the specific structure will not be described in detail. The innovation of this embodiment is mainly to omit the original barrier rib 1 and add an adjustment plate 7. This not only increases the space in the cotton seed channel and improves the efficiency of the saw blade 4 in pulling the cotton, but also prevents the cotton from falling without being pulled by the saw blade 4 during unpacking.
[0025] A rotating shaft 6 is rotatably connected to the frame 2 of the cotton gin. This shaft 6 runs parallel to and along the length of the cotton feed roller 3. An adjustment plate 7 is fixed to the shaft 6. This elongated plate is fixedly connected to the shaft 6 along its long side. The plate 7 is located below the cotton feed roller 3, with the side not connected to the shaft 6 extending toward the edge of the saw blade 4. This creates a gap between the plate 7 and the edge of the saw blade 4. This gap allows the saw blade 4 to rotate normally without causing any cotton to fall through the blade.
[0026] like Figure 3 As shown, a positioning device is fixed on the rotating shaft 6 for controlling the angle between the adjustment plate 7 and the tangent line of the saw blade 4. By adjusting the rotation angle of the rotating shaft 6 through the positioning device, the rotating shaft 6 drives the adjustment plate 7 to rotate, changing the angle between the adjustment plate 7 and the tangent line of the saw blade 4, and increasing or decreasing the gap between the adjustment plate 7 and the edge of the saw blade 4 to adapt to different types of cotton.
[0027] like Figure 4As shown, the positioning device includes a handle 9 hinged on the rotating shaft 6 and a positioning plate 12 fixed to the frame 2. In this embodiment, one end of the rotating shaft 6 extends out of the frame 2, and the end of the rotating shaft 6 extending out of the frame 2 is sleeved and fixed with a sleeve 8. One end of the handle 9 is hinged on the sleeve 8, so that the handle 9 can rotate toward or away from the frame 2. The other end of the handle 9 is fixed with a positioning ball 10, and the handle 9 is fixed with an insert 11. The positioning plate 12 is fixed to the frame 2. The positioning plate 12 is an arc-shaped circular plate centered on the rotating shaft 6. The positioning plate 12 is provided with multiple grooves 13 arranged along its height direction. By snapping the inserts 11 of the handle 9 into different grooves 13, the handle 9 can drive the rotating shaft 6 to rotate to different angles, thereby achieving the purpose of changing the setting angle of the adjustment plate 7. Since the positioning plate 12 is arc-shaped, after the insert 11 of the handle 9 is engaged with the groove 13 of the positioning plate 12, the positioning ball 10 abuts against the positioning plate 12, which can improve the stability of the fixing of the rotating shaft 6 and make the insert 11 on the handle 9 and the groove 13 of the positioning plate 12 not easily detached.
[0028] The cotton feeding roller 3 is driven by a brake motor, which is a motor with an internal locking structure. After unpacking, the brake motor stops rotating immediately. The locking structure prevents the cotton feeding roller 3 from continuing to rotate under the action of inertia, so that the cotton feeding roller 3 also stops rotating immediately and will not continue to convey the cotton to the saw blade 4 and the rib 5. Under the blocking action of the adjustment plate 7, it can more effectively prevent the cotton from falling without being hooked, thereby improving production efficiency.
[0029] To use this embodiment, the handle 9 is rotated to a position where the insert 11 is not engaged with the groove 13 of the positioning plate 12. The shaft 6 is then rotated to position the adjustment plate 7 at an appropriate distance from the edge of the saw blade 4. The handle 9 is then rotated toward the positioning plate 12, engaging the insert 11 of the handle 9 within the groove 13 of the positioning plate 12 to secure the adjustment plate 7. During normal operation of the cotton gin, the feed roller 3 pushes cotton into the space formed between the feed roller 3, the adjustment plate 7, and the ribs 5. The cotton is then drawn by the saw blade 4 into the collection bin, and the cotton seeds fall through the gap between the adjustment plate 7 and the ribs 5. When the bin is opened, the brake motor is urgently stopped, causing the feed roller 3 to also stop. No new cotton is fed into the space formed by the feed roller 3, the adjustment plate 7, and the ribs 5, further preventing cotton from falling through the seed channel without being drawn.
[0030] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
