Description

A waste textile opening machine Technical Field

[0001] The invention belongs to the technical field of textile machinery manufacturing, and relates to the improvement of an opener, in particular to an opener for waste textiles. Background Art

[0002] Opening machines are mainly used to loosen fibers, cotton, textiles and other materials. They tear large pieces of fabric into small pieces or bundles, and separate them during the opening process.

[0003] Current processing of textile waste, particularly opening of used clothing and fabric, typically involves repeated opening with multiple opening machines to ensure optimal opening. However, the semi-finished product after opening cannot fully meet the requirements of subsequent processing steps. Small pieces of fabric and recycled fibers become intermingled, necessitating repeated opening. Repeated opening damages the already opened recycled fibers, affecting their mechanical properties and length. Furthermore, repeated opening of recycled fibers reduces the yield of the entire opening process, impacting costs. Sorting out the pieces of fabric requires significant manual effort, resulting in extremely low efficiency and difficult-to-control quality control.

[0004] A Chinese patent application titled "Fiber Regeneration Rag Fiber Separation Device" (Application No. 202221314106.5) discloses a utility model patent. This patent utilizes a cloth slide to separate rags and fibers. The principle is that the raw material slows down after passing through the cloth slide, and the difference in specific gravity between the fibers and rags is utilized to separate the fibers and rags through negative pressure, facilitating subsequent fiber combing and spinning. This patented technology avoids repeated fiber opening that damages the fiber's physical properties. However, this patent still has the following problems:

[0005] 1. The fiber separation device for fiber regeneration rags is an independent unit that needs to be used in conjunction with the existing opener. It cannot be organically integrated with the opener, further simplifying the structure of the opener and reducing equipment costs. 2. The degree of automation and production efficiency are low. 3. The fiber separation device for fiber regeneration rags cannot be automatically and adaptively adjusted according to different fiber content to achieve more thorough separation of fiber cloth pieces.

[0006] How to design a waste textile opening machine that can more thoroughly separate fibers from fabric, allowing the regenerated fibers to be directly fed to the next process and the fabric to be collected and opened repeatedly, with a high degree of automation and high production efficiency, while reducing overall manufacturing costs and floor space, is a pressing technical challenge in this field.

It also includes a fiber-cloth separation device, with a safety cover 3 positioned above the opening beater 5. The fiber-cloth separation device comprises a negative pressure blower, a conveying channel 6, a deceleration channel 14, and an airflow cutting plate 7. The conveying channel 6 is disposed transversely within the housing. One end of the conveying channel 6 communicates with the opening beater channel below the opening beater 5, and the other end of the conveying channel 6 communicates with the inlet of the deceleration channel 14. The outlet of the deceleration channel 14 connects to an upward fiber outlet 9 and a downward cloth outlet 12. An air supply mesh plate 13 is disposed on the bottom surface of the deceleration channel 14. The airflow cutting plate 7, positioned centrally within the deceleration channel 14, divides the deceleration channel 14 into an upper channel and a lower channel. A negative pressure blower (not shown) communicates with the fiber outlet 9 to form an airflow for conveying regenerated fibers. The cloth collection port is connected to a material recycling device.

[0028] Furthermore, the cross-section of the above-mentioned deceleration channel 14 gradually increases from the inlet end to the outlet end, the top surface of the above-mentioned airflow cutting plate 7 is a plane, and the bottom surface is a smooth convex surface. Both ends of the airflow cutting plate 7 are pointed, and the top surface of the airflow cutting plate 7 is inclined, and the end close to the fiber outlet 9 is the high end.

[0029] Specifically, the airflow cutting plate 7 is equipped with a controller, an image sensor 10, an electric push rod 15, and a rotating shaft 8. The image sensor 10 and the electric push rod 15 are respectively connected to the controller. The rotating shafts 8 are respectively provided on both sides of the deceleration channel 14 and are respectively connected to the two side surfaces of the airflow cutting plate 7. The electric push rod 15 is provided outside the deceleration channel 14. The movable end of the electric push rod 15 is connected to the rotating shaft 8 and is used to drive the airflow cutting plate 7 to rotate around the rotating shaft 8. The image sensor 10 is used to detect the proportion of cloth pieces in the regenerated fiber in the fiber outlet 9. The controller automatically controls the electric push rod 15 to adjust the inclination angle of the top surface of the airflow cutting plate 7 in real time based on the proportion of cloth pieces in the regenerated fiber detected by the image sensor 10.

[0030] Furthermore, the outlet end of the deceleration channel 14 extends out of the casing, and the outlet of the deceleration channel 14 is connected to the vertically arranged square discharge pipe 11, and the fiber outlet 9 and the cloth outlet 12 are the upper port and the lower port of the square discharge pipe 11 respectively.

[0031] Furthermore, the top and bottom surfaces of the conveying channel 6 are both trapezoidal, the top and bottom surfaces of the conveying channel 6 are arranged in parallel, and the width of the end of the conveying channel 6 connected to the deceleration channel 14 is the narrowest.

[0032] Furthermore, the top surface of the above-mentioned deceleration channel 14 is an inclined surface, the connection end between the top surface of the deceleration channel 14 and the conveying channel 6 is the lowest end, the bottom surface of the above-mentioned deceleration channel 14 and the bottom surface of the conveying channel 6 are an integrated structure, and the two are on the same horizontal plane.

[0033] The working principle of the waste textile opening machine of the present invention is as follows: waste textile raw materials or semi-finished products enter the opening area through the cotton feeding plate 1 and the cotton feeding roller 2, are opened by the opening beater 5, and after impurities are removed by the adjustable arc-shaped leaking bottom 4, enter the fiber cloth piece separation device through the discharge port, the inlet cross-section of the fiber cloth piece separation device gradually expands, the raw material and airflow are decelerated and diffused in the deceleration channel 14, and under the influence of the air flow added by the air supply mesh plate 13, the raw material is quickly layered, the light regenerated fiber is in the upper channel, the heavier cloth pieces are distributed in the upper channel and the lower channel, and the air flow is cut by the air flow cutting plate 7, the regenerated fiber enters the fiber outlet 9 through the upper channel, and the cloth pieces enter the square discharge pipe 11 through the lower channel, and hit the vertical inner wall of the square discharge pipe 11. The raw material slows down again after the collision, and due to the different weight and shape characteristics of the regenerated fiber and the cloth pieces, the regenerated fiber and the cloth pieces will be separated again, the regenerated fiber enters the fiber outlet 9 through the negative pressure, and the cloth pieces fall into the cloth piece outlet 12.

[0034] In a specific embodiment, the image sensor 10 automatically detects the cloth content in the fiber outlet 9 and compares the detected value with the set value. According to the comparison result, the electric push rod 15 is actuated to drive the airflow cutting plate 7 to swing around the rotating shaft 8, and adjust the opening angle between the top surface of the airflow cutting plate 7 and the air supply mesh plate 13 to achieve more thorough separation of the fiber cloth.
