[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0038] like Figures 1-5 As shown, this embodiment provides a cotton blending machine cotton dispensing device, including a main shell 1, an arc-shaped channel 12, and multiple rotating rollers 30. Figure 4 As shown, a main conveyor belt 11 is horizontally arranged inside the main shell 1, and an arc-shaped channel 12 is located inside the main shell 1. The arc-shaped channel 12 is located at the conveying tail end of the main conveyor belt 11. The arc-shaped channel 12 includes a main baffle 120, an inner arc-shaped plate 121, and an outer arc-shaped plate 122. The main baffle 120 is fixed to the inner wall of the bottom end of the main shell 1. The two ends of the inner arc-shaped plate 121 and the outer arc-shaped plate 122 are fixed to the inner walls of both sides of the main shell 1, and the gap between the inner arc-shaped plate 121 and the outer arc-shaped plate 122 forms the arc-shaped channel 12. A discharge port 13 is opened in the main shell 1, and a flap 20 is rotatably arranged in the discharge port 13. The flap 20 is located directly below the feed port of the arc-shaped channel 12. The discharge port of the arc-shaped channel 12 is located directly above the main conveyor belt 11. Figure 5 As shown, multiple rotating rollers 30 are rotatably arranged inside the main housing 1. Two rotating rollers 30 are arranged side-by-side at the conveying end of the main conveyor belt 11. Multiple rotating rollers 30 are evenly distributed along the arc-shaped channel 12. Each rotating roller 30 has multiple support groups 31 evenly distributed along its axial direction. Each support group 31 includes multiple support rods 32, one end of which is fixedly connected to the rotating roller 30. The support rods 32 of adjacent rotating rollers 30 are staggered. Figure 1 As shown, multiple cotton distribution boxes 40 are arranged side-by-side at the upstream end of the main conveyor belt 11, and each cotton distribution box 40 has an observation port 400 in its upper middle part. Glass is installed at the observation port 400. The multiple cotton distribution boxes 40 are arranged along the conveying direction of the main conveyor belt 11. A support conveyor belt 41 is horizontally installed at the bottom of each cotton distribution box 40, as shown... Figure 4 As shown, one end of the branch conveyor belt 41 extends out of the cotton distribution box 40 and is located directly above the main conveyor belt 11. The top of the cotton distribution box 40 is connected to a feeding channel 42. Multiple independent cotton distribution boxes 40 are arranged side-by-side at the upstream end of the main conveyor belt 11, each used to store different types of raw materials, such as rock wool, glass wool, and ceramic fiber. The raw materials are fed into each cotton distribution box 40 through the feeding channel 42 at the top, achieving classified storage. Each cotton distribution box 40 has a branch conveyor belt 41 at its bottom, with one end extending into the box and the other end extending out and suspended directly above the main conveyor belt 11. The raw materials output from each branch conveyor belt 41 fall into the main conveyor belt 11, achieving initial mixing during the conveyor belt's operation.

[0039] The raw material is conveyed via the main conveyor belt 11 to the feed inlet of the arc-shaped channel 12 located directly above it. At this time, the main conveyor belt 11 is in operation, preparing for subsequent conveying. After the raw material enters the arc-shaped channel 12, multiple rollers 30 evenly distributed along the path within the arc-shaped channel begin to rotate at low speed. Each roller 30 has axially arranged support groups 31, and the support rods 32 of adjacent rollers 30 are staggered to form alternating action zones. The support rods 32 gently agitate and comb the fiber bundles, gradually breaking up the agglomerated raw material. At the same time, the guiding effect of the arc-shaped channel 12 causes the fibers to roll forward along a specific trajectory, avoiding fiber breakage caused by high-speed cutting. The fully mixed raw material falls back to the tail end of the main conveyor belt 11 through the discharge port at the end of the arc-shaped channel 12. The above actions are repeated to complete the repeated mixing of the raw material, thereby achieving a uniform and thorough mixing of the raw material.

[0040] like Figure 2 As shown, the cotton blending machine's cotton dispensing device also includes multiple first motors 33, each corresponding to a multiple rotating rollers 30. The base of each first motor 33 is fixedly connected to the main housing 1, and the output shaft of each first motor 33 passes through the main housing 1 and coaxially connects with the rotating rollers 30. Driving the first motors 33 causes them to rotate, thus rotating the rotating rollers 30. Figure 1 As shown, the cotton blending device also includes a shaft 21 and a cylinder 22. One end of the shaft 21 is fixedly connected to a connecting plate 23, and the end of the connecting plate 23 away from the shaft 21 is hinged to the piston rod of the cylinder 22. The cylinder seat of the inclined cylinder 22 is hinged to the main housing 1. The other end of the shaft 21 passes through the main housing 1 and is fixedly connected to the flip plate 20. When the piston rod of the cylinder 22 extends and retracts, the cylinder 22 drives the shaft 21 to rotate through the connecting plate 23. The shaft 21 drives the flip plate 20 to flip. When the flip plate 20 is in a horizontal state, it can block the discharge port 13. When the flip plate 20 is in a vertical state, the discharge port is relatively open. After the blending is completed, the cotton is discharged. Each cotton distribution box 40 has a rotating shaft 43 in the middle. Two driven sprockets 44 are fixedly mounted on one end of the shaft 43, and the other end of the shaft 43 passes through the cotton distribution box 40 and is fixedly mounted on a rotating plate 45. An electronic scale is mounted on the rotating plate 45. The electronic scale uses existing technology and will not be described in detail; models such as IND780, ICS689, Entris II Industrial, and Voyager V can be selected. The rotating plate 45 is located between the discharge port of the feed channel 42 and the branch conveyor belt 41. The axial direction of the rotating shaft 43 is along the conveying direction of the branch conveyor belt 41. The branch conveyor belt 41 is offset perpendicularly to the main conveyor belt 11. Figure 2As shown, the cotton blending machine's cotton dispensing device also includes a second motor 50. The base of the second motor 50 is fixedly connected to the cotton dispensing box 40, and the output shaft of the second motor 50 is fixedly connected to the drive sprocket 51. A chain 52 is sleeved on the two driven sprockets 44 on the two sides of the rotating shaft 43, adjacent to the driven sprockets 44 or the drive sprockets 51. Multiple partitions 60 are evenly distributed along the conveying direction of the main conveyor belt 11 and the branch conveyor belt 41. The partitions 60 are arranged along the width direction of the main conveyor belt 11 or the branch conveyor belt 41.

[0041] Raw materials are fed into each cotton distribution box 40 through the feeding channel 42 at the top, first landing on the rotating plate 45 in the middle of the box. The rotating plate 45 is connected to an electronic scale fixed to a rotating shaft 43, which weighs the falling raw materials in real time. When the preset proportion is reached, the rotating shaft 43 rotates, and the rotating plate 45 tilts to pour the raw materials onto the lower branch conveyor belt 41, achieving precise quantitative output. Two driven sprockets 44 are fixedly mounted on one end of the rotating shaft 43, and the other end is fixed to the cotton distribution box 40. A second motor 50 drives the drive sprocket 51, which in turn drives the driven sprockets 44 to rotate the raw materials via a chain 52. The chain 52 transmission ensures that the rotating shaft 43 and the branch conveyor belt 41 move synchronously, preventing raw material accumulation or spillage. The branch conveyor belts 41 of each cotton distribution box 40 are offset perpendicular to the main conveyor belt 11. After being guided by the rotating plate 45, the raw materials are conveyed along the direction of the branch conveyor belt 41 to directly above the main conveyor belt 11. The partition 60 is fixedly installed along the conveying direction of the branch conveyor belt 41. The raw materials output from the branch conveyor belt 41 fall sequentially into the main conveyor belt 11, which runs at a low speed. The raw materials at the end of the main conveyor belt 11 are conveyed to the arc-shaped channel 12. The evenly distributed rollers 30 in the channel, through low-speed rotation and the design of staggered support rods 32, gently comb and disperse the raw materials to avoid fiber breakage. After the raw materials flow out of the arc-shaped channel 12, they are differentially kneaded by two rollers 30 arranged side by side at the end of the main conveyor belt 11.

[0042] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
