Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a grading and screening device for colored cotton raw materials. Background Technology

[0002] Colored cotton, also known as naturally colored cotton, is a special type of cotton cultivated through modern bioengineering technology. Its unique feature is that the cotton fibers naturally possess colors such as red, yellow, green, brown, gray, and purple when they are unfurled. It can be woven into fabric without dyeing. This fabric is not only free of the toxicity of chemical dyes, but is also highly praised for its softness and elasticity.

[0003] In the prior art, Chinese patent CN222369649U discloses a color sorting device for cotton seed processing. Small cotton seeds fall directly through a small-hole screen onto the partition plate of a second storage box, while large cotton seeds fall through a large-hole screen into the interior of the second storage box. The largest cotton seeds are then stored in the first storage box, enabling the sorting and classification of cotton seeds of different sizes. However, in practical applications, workers still need to manually add raw materials to the sorting machine during the grading and sorting process. This can lead to problems such as adding too much or too little raw material, resulting in errors in raw material sorting or low sorting efficiency. Therefore, we disclose a grading and sorting device for colored cotton raw materials. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a grading and screening device for colored cotton raw materials to solve the problem of adding too much or too little raw material during screening.

[0005] To achieve the above objectives, this utility model provides a grading and screening device for colored cotton raw materials, including a storage frame. A motor is fixedly connected to one end of the storage frame, and a belt assembly is fixedly sleeved at the output end of the motor. A bevel gear assembly is fixedly sleeved at the upper end of the belt assembly. A raw material box is placed on one side of the storage frame, and a discharge hole is provided at the bottom of the raw material box. A first partition and a second partition are fixedly connected to both ends of the inner cavity of the raw material box, respectively. The second partition is located above the discharge hole of the raw material box, and the discharge hole is located above the storage frame. The bevel gear assembly... A material feeding plate is fixedly sleeved through the middle of the material box into the inner cavity. The material feeding plate is located below the second partition. Several fixing plates are fixedly connected to both sides of the storage frame. A first connecting rod is movably sleeved on the upper end of the fixing plate. A screening frame is fixedly connected to one end of the first connecting rod. A spring is fixedly connected to one end of the screening frame. One end of the spring is fixedly connected to the fixing plate. Several screening holes are opened at the bottom of the screening frame. One end of the screening frame is inclined to the horizontal plane. The storage frame is located below the screening frame for storage.

[0006] Preferably, the bevel gear set is rotatably connected to the raw material box, the first partition is located above the second partition, a gap is left between the first partition and the second partition, the ends of the first partition and the second partition located in the middle of the raw material box are on the same vertical line, and the cross-sections of the first partition and the second partition are both triangular.

[0007] Preferably, a circular plate is fixedly sleeved at the output end of the motor, a third connecting rod is rotatably connected to one end of the circular plate, a limit block is fixedly connected to one end of the storage frame, a first moving groove and a second moving groove are provided on one side of the limit block, the third connecting rod is slidably connected in the first moving groove, a second connecting rod is rotatably connected to one end of the third connecting rod, the second connecting rod passes through the first moving groove to the outside of the limit block and a connecting block is fixedly connected to one end, the connecting block is fixedly connected to the screening frame, a limit rod is fixedly connected below the connecting block, and the limit rod is slidably connected in the second moving groove.

[0008] Preferably, one end of the screening frame is located below the raw material box, and the aperture values ​​of the plurality of screening holes increase from below the raw material box to the direction away from the raw material box.

[0009] Preferably, the screening frame includes two plates, one end of which is fixedly connected. The plate of the screening frame located below the raw material box is parallel to the horizontal plane, and the other plate of the screening frame is inclined downwards away from the raw material box.

[0010] Preferably, the inner cavity of the storage frame is fixedly connected to several plates, dividing the inner cavity of the storage frame into several independent spaces. A guide block is fixedly connected to the bottom end of the storage frame. Several holes are opened on one side of the storage frame. A door panel is rotatably connected to one end of the storage frame. Several limiting frames are fixedly connected to the upper end of the storage frame.

[0011] Preferably, the handle has a U-shaped side and the pin has an L-shaped rod.

[0012] The beneficial effects of this utility model are as follows: After the motor is started, it can simultaneously drive the belt assembly and the circular plate to rotate. The belt assembly can drive the bevel gear assembly to rotate, and the raw materials in the raw material box can fall through the discharge hole. The bevel gear assembly can drive the material-pushing plate to rotate, pushing the raw materials on one side of the second partition to fall through the discharge hole below the second partition. This allows the raw materials to fall automatically in batches and in quantities, avoiding the problem of too much or too little raw materials falling at once, which would cause accumulation and affect the screening results or screening efficiency. It also reduces the workload of the staff. The first partition prevents the raw materials in the raw material box from accumulating too much raw materials, which would put too much pressure on the raw materials at the bottom and affect the material-pushing plate's ability to move the raw materials. This allows the raw materials at the top of the first partition to fall through the gap between the first and second partitions to the bottom of the material-pushing plate without affecting the falling of the raw materials. This allows the raw material box to accumulate a larger amount of raw materials at once, avoiding the need for the staff to frequently add raw materials to the raw material box and improving work efficiency.

[0024] like Figures 1-6As shown, a grading and screening device for colored cotton raw materials includes a storage frame 1. A motor 2 is fixedly connected to one end of the storage frame 1. A belt assembly 3 is fixedly sleeved at the output end of the motor 2. A bevel gear assembly 4 is fixedly sleeved at the upper end of the belt assembly 3. A raw material box 6 is placed on one side of the storage frame 1. A discharge hole is opened at the bottom of the raw material box 6. A first partition 7 and a second partition 8 are fixedly connected to both ends of the inner cavity of the raw material box 6, respectively. The second partition 8 is located above the discharge hole of the raw material box 6, and the discharge hole is located above the storage frame 1. A material-pulling plate 5 is fixedly sleeved through the middle of the bevel gear assembly 4 into the inner cavity of the raw material box 6. The material-pulling plate 5 is located below the second partition 8. Several fixing plates 9 are fixedly connected to both sides of the storage frame 1. A first connecting rod 1 is movably sleeved at the upper end of the fixing plate 9. 0. A screening frame 12 is fixedly connected to one end of the first connecting rod 10. A spring 11 is fixedly connected to one end of the screening frame 12. One end of the spring 11 is fixedly connected to the fixing plate 9. Several screening holes 22 are opened at the bottom of the screening frame 12. One end of the screening frame 12 is inclined to the horizontal plane. The storage box 1 is located below the screening frame 12 for storage. The bevel gear set 4 is rotatably connected to the raw material box 6. The first partition 7 is located above the second partition 8. There is a gap between the first partition 7 and the second partition 8. The ends of the first partition 7 and the second partition 8 located in the middle of the raw material box 6 are on the same vertical line. The cross-section of the first partition 7 and the second partition 8 are both triangular. A circular plate 20 is fixedly sleeved at the output end of the motor 2. A third connecting rod 20 is rotatably connected to one end of the circular plate 20. A connecting rod 15 is attached to one end of a storage frame 1, and a limiting block 16 is fixedly connected to it. A first moving groove 17 and a second moving groove 18 are provided on one side of the limiting block 16. A third connecting rod 15 is slidably connected within the first moving groove 17. A second connecting rod 14 is rotatably connected to one end of the third connecting rod 15. The second connecting rod 14 passes through the first moving groove 17 to the outside of the limiting block 16, and a connecting block 13 is fixedly connected to one end. The connecting block 13 is fixedly connected to the screening frame 12. A limiting rod 19 is fixedly connected below the connecting block 13 and slidably connected within the second moving groove 18. One end of the screening frame 12 is located below the raw material box 6. The aperture values ​​of several screening holes 22 increase from below the raw material box 6 to the direction away from the raw material box 6. The screening frame 12 includes two... The material storage frame 12 consists of two plates, one end of which is fixedly connected. The plate below the raw material box 6 is parallel to the horizontal plane, while the other plate of the screening frame 12 is inclined downwards away from the raw material box 6. During use, a motor 2 is fixedly connected to one end of the storage frame 1, and a belt assembly 3 is fixedly sleeved at the output end of the motor 2. This fixes the position of the motor 2 within the storage frame 1, allowing the motor 2 to drive the belt assembly 3 to rotate. A bevel gear assembly 4, comprising two bevel gears, is fixedly sleeved at the upper end of the belt assembly 3, allowing the belt assembly 3 to drive the bevel gear assembly 4 to rotate. The raw material box 6 is placed on one side of the storage frame 1, and a discharge hole is provided at the bottom of the raw material box 6, allowing the raw material inside the box 6 to fall through the discharge hole.A first partition 7 and a second partition 8 are fixedly connected to both ends of the inner cavity of the raw material box 6. The second partition 8 is located above the material discharge hole of the raw material box 6, which is located above the storage frame 1. This allows the second partition 8 to prevent the raw material accumulated in the raw material box 6 from falling directly through the material discharge hole. A material-pulling plate 5 is fixedly sleeved through the middle of the bevel gear set 4 into the inner cavity of the raw material box 6. The material-pulling plate 5 is located below the second partition 8, allowing the bevel gear set 4 to drive the material-pulling plate 5 to rotate, pushing the raw material on one side of the second partition 8 to the bottom of the second partition 8 and falling through the material discharge hole. This allows the raw material to fall automatically in batches and in quantitative quantities, avoiding the problem of excessive raw material falling at once and accumulating, which would affect the screening results or screening efficiency. It also reduces the workload of the staff. Several fixed plates 9 are fixedly connected to both sides. A first connecting rod 10 is movably sleeved on the upper end of the fixed plate 9. A screening frame 12 is fixedly connected to one end of the first connecting rod 10. A spring 11 is fixedly connected to one end of the screening frame 12. One end of the spring 11 is fixedly connected to the fixed plate 9. Several screening holes 22 are opened at the bottom of the screening frame 12. One end of the screening frame 12 is inclined to the horizontal plane, so that the position of the storage frame 1 is fixed to the fixed plate 9. The fixed plate 9 restricts the movement range of the screening frame 12 through the first connecting rod 10 and the spring 11, so that the screening frame 12 can swing horizontally to a certain extent, which helps the raw material in the screening frame 12 to fall. During the falling process, it falls through the screening holes 22 of appropriate size, completing the automatic screening of the raw material. A partition 7 is located above the second partition 8. A gap exists between the first partition 7 and the second partition 8. This allows the first partition 7 to prevent excessive pressure from the bottom of the material box 6 caused by excessive material accumulation, which could affect the movement of the material feeding plate 5. It also allows material at the top of the first partition 7 to fall through the gap between the first partition 7 and the second partition 8 to the bottom of the material feeding plate 5 without affecting its descent. This allows the material box 6 to hold a larger amount of material at once, avoiding the need for frequent additions by workers. The first partition 7 and the second partition 8 are located on the same vertical line at their midpoints in the material box 6, preventing material from falling directly to the bottom. The triangular cross-sections of both the first partition 7 and the second partition 8 further facilitate this process. The raw materials, under their own gravity, fall along the first partition 7 to the top of the second partition 8 and then to the bottom of the raw material box 6. A third connecting rod 15 is rotatably connected to one end of the circular plate 20, so that the rotation of the circular plate 20 will drive the third connecting rod 15 to move. A limit block 16 is fixedly connected to one end of the storage frame 1. A first moving groove 17 and a second moving groove 18 are opened on one side of the limit block 16. The third connecting rod 15 is slidably connected in the first moving groove 17. A second connecting rod 14 is rotatably connected to one end of the third connecting rod 15. The second connecting rod 14 passes through the first moving groove 17 and is fixedly connected to a connecting block 13 at one end outside the limit block 16. The connecting block 13 is fixedly connected to the screening frame 12. A limit rod 19 is fixedly connected to the lower part of the connecting block 13.The limiting rod 19 is slidably connected to the second moving groove 18, which fixes the position of the limiting block 16 in the storage frame 1. The limiting block 16 restricts the movement direction of the third connecting rod 15 through the first moving groove 17, thereby causing the third connecting rod 15 to reciprocate along the first moving groove 17. At the same time, the second moving groove 18 restricts the movement position of the connecting block 13 through the limiting rod 19, so that the third connecting rod 15 drives the connecting block 13 and the screening frame 12 to reciprocate through the second connecting rod 14, causing the screening frame 12 to shake, which helps the raw material to move and be screened. Since one end of the screening frame 12 is located below the raw material box 6, the aperture values ​​of several screening holes 22 are changed from the original The material bin 6 widens from its lower part towards the direction away from it, causing the material falling from the bin 6 to reach the top of the screening frame 12. The material then falls through appropriately sized screening holes 22, completing the automatic screening. The screening frame 12 consists of two plates: the plate below the material bin 6 is parallel to the horizontal plane, while the other plate slopes downwards away from the bin 6. This prevents the material from immediately sliding down after falling from the bin 6 to the top of the screening frame 12; instead, it remains suspended for a period of time, causing the material to collide with each other and dislodge surface dust, which then falls through the screening holes 22, completing the self-cleaning process. This simple operation facilitates subsequent processing of the material.

[0025] As a preferred embodiment of this example, Figure 4 and Figure 6As shown, several plates are fixedly connected to the inner cavity of the storage frame 1, dividing the inner cavity of the storage frame 1 into several independent spaces. A guide block 23 is fixedly connected to the bottom end of the storage frame 1. Several holes are opened on one side of the storage frame 1. A door panel 21 is rotatably connected to one end of the storage frame 1. Several limit frames 26 are fixedly connected to the upper end of the storage frame 1. A handle 24 is fixedly connected to the upper end of the door panel 21. A pin 25 passes through the upper end of the handle 24. The pin 25 is movably sleeved with the limit frame 26. The side of the handle 24 is U-shaped, and the pin 25 is an L-shaped rod. By fixing several plates to the inner cavity of the storage frame 1, dividing the inner cavity of the storage frame 1 into several independent spaces, the storage frame 1 is divided into several spaces, separating the falling raw materials. A guide block 23 is fixedly connected to the bottom end of the storage frame 1, and several holes are opened on one side of the storage frame 1. Several holes allow the raw materials in the storage frame 1 to move towards the holes through the guide block 23, facilitating the collection of raw materials and making it convenient for workers to operate. A door panel 21 is rotatably connected to one end of the storage frame 1, which can prevent the raw materials in the storage frame 1 from sliding out. Several limiting frames 26 are fixedly connected to the upper end of the storage frame 1, and a handle 24 is fixedly connected to the upper end of the door panel 21. A pin 25 passes through the upper end of the handle 24, and the pin 25 is movably connected to the limiting frame 26. The storage frame 1 fixes the position of the limiting frame 26, so that the limiting frame 26 restricts the position of the pin 25, thereby restricting the position of the handle 24 and the door panel 21, thus fixing the position of the door panel 21. The handle 24 has a U-shaped side, and the pin 25 has an L-shaped rod, making the handle 24 and the pin 25 easy to use.
