Description

Technical Field

[0001] This utility model relates to the field of recycled polyester staple fiber technology, and in particular to a multi-stage crushing device for the production of recycled polyester staple fiber. Background Technology

[0002] Recycled polyester staple fiber refers to fibers made from raw materials such as waste polyester bottle flakes, polyester fabrics, waste spinning fibers, foam materials, and pulp blocks through processes including crushing, washing, drying, melt extrusion, spinning, winding, bundling, drawing, crimping, heat setting, and cutting. These raw materials, after processing, can form polyester staple fibers of varying lengths. Recycled polyester staple fiber is not only an environmentally friendly material but also has multiple uses. As a type of environmentally friendly fiber, it possesses characteristics such as non-deformation, non-shrinkage, and non-frizziness, making it suitable for the production of various environmentally friendly fabrics. In apparel fabric production, recycled polyester staple fiber can be blended with other fibers, with a blending rate as high as approximately 90%, and is widely used in various textiles. Furthermore, recycled polyester staple fiber can also be used to produce nonwoven fabrics and hollow fibers, and as filling materials such as wadding.

[0003] In the current production of recycled polyester staple fiber, the raw materials need to be crushed first. During the crushing process, many fine fragments are generated. These fragments adhere to the inside of the crushing device and, if not cleaned for a long time, can easily affect the crushing effect. After crushing, the fiber fragments fall to the bottom of the crushing device and are output from the conveying pipe at the bottom of the device. However, because the fiber fragments are relatively light, they easily stick to the conveying pipe, which affects the output of fiber fragments. Therefore, this process needs to be improved.

[0065] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a multi-stage crushing device for the production of recycled polyester staple fiber.

[0066] A multi-stage crushing device for producing recycled polyester staple fiber includes a support barrel 1 and a support ring 2, with the support ring 2 fixedly connected to the support barrel 1. It also includes: multiple support legs 3 evenly arranged on the support ring 2 and fixedly connected to it; a support cover 4 disposed on the support barrel 1 and detachably fixedly connected to it; a feed inlet 5 on the support cover 4; a discharge pipe 6 disposed on the support barrel 1 and fixedly connected to it; a drive frame 7 fixedly connected to the support cover 4; a drive motor 8 fixedly connected to the drive frame 7; a drive shaft 9 detachably fixedly connected to the output end of the drive motor 8 and rotatably connected to the support cover 4; multiple crushing blades 10 evenly arranged on the drive shaft 9 and fixedly connected to it; a cleaning mechanism disposed on the support cover 4 for cleaning the inner wall of the support barrel 1; and a vibration mechanism disposed on the support ring 2 for vibrating the support barrel 1.

[0067] Reference Figure 4 In a preferred embodiment, the cleaning mechanism includes: a cleaning frame 11, which is disposed on the support cover 4 and is detachably fixedly connected to the support cover 4; a cleaning motor 12, which is fixedly connected to the cleaning frame 11; a cleaning shaft 13, which is detachably fixedly connected to the output end of the cleaning motor 12; and a sliding component, which is disposed on the support cover 4.

[0068] This configuration allows the cleaning motor 12 to rotate when it is running, causing the cleaning shaft 13, which is detachably and fixedly connected to the output end of the cleaning motor 12, to rotate and drive the sliding components.

[0069] Reference Figure 4 In a preferred embodiment, the sliding component includes: a first sliding rod 14, which is disposed on the support cover 4 and fixedly connected to the support cover 4; a second sliding rod 15, which is fixedly connected to the support cover 4; a third sliding rod 16, which is fixedly connected to the support cover 4; and a sliding ring 17, which is disposed on the cleaning shaft 13, rotatably connected to the cleaning shaft 13, and slidably connected to the first sliding rod 14 and the second sliding rod 15.

[0070] This configuration allows the sliding ring 17, which is rotatably connected to the cleaning shaft 13, to rotate, thereby causing the sliding block to slide on the first sliding rod 14, the second sliding rod 15, and the third sliding rod 16, thus cleaning the inner wall of the support barrel 1.

[0071] Reference Figure 5In a preferred embodiment, the vibration mechanism includes: a first vibration plate 18, disposed on the support ring 2 and fixedly connected to the support ring 2; a second vibration plate 19, fixedly connected to the support ring 2; a vibration frame 20, fixedly connected to the first vibration plate 18; a vibration motor 21, fixedly connected to the vibration frame 20; a vibration shaft 22, detachably fixedly connected to the output end of the vibration motor 21 and rotatably connected to the first vibration plate 18; and a rotating component disposed on the vibration shaft 22.

[0072] This configuration allows the vibration motor 21 to rotate when it is running, driving the vibration shaft 22, which is detachably and fixedly connected to the output end of the vibration motor 21, to rotate the rotating components.

[0073] Reference Figure 5 In a preferred embodiment, the rotating component includes: a first rotating plate 23, disposed on the vibration shaft 22 and fixedly connected to the vibration shaft 22; a first rotating shaft 24, fixedly connected to the first rotating plate 23; a second rotating plate 25, fixedly connected to the first rotating shaft 24; a second rotating shaft 26, fixedly connected to the second rotating plate 25 and rotatably connected to the second vibration plate 19; a rotating cylinder 27, fixedly connected to the first rotating shaft 24; and a connecting component disposed on the first vibration plate 18.

[0074] This configuration causes the first rotating plate 23, which is fixedly connected to the vibration shaft 22, to rotate, the second rotating plate 25, which is fixedly connected to the first rotating shaft 24, to rotate, and the second rotating shaft 26, which is fixedly connected to the second rotating plate 25, to rotate on the second vibration plate 19, thereby driving the rotating cylinder 27, which is fixedly connected to the first rotating shaft 24, to rotate.

[0075] Reference Figure 5 In a preferred embodiment, the connecting component includes: a connecting frame 28, which is disposed on the first vibrating plate 18 and fixedly connected to the first vibrating plate 18; a first connecting shaft 29, which is fixedly connected to the connecting frame 28; a connecting plate 30, which is rotatably connected to the first connecting shaft 29; a second connecting shaft 31, which is rotatably connected to the connecting plate 30; and a transmission component, which is disposed on the second connecting shaft 31.

[0076] This configuration allows the connecting plate 30, which is rotatably connected to the second connecting shaft 31, to rotate around the axis of the first connecting shaft 29, which is fixedly connected to the connecting frame 28.

[0077] Reference Figure 5 In a preferred embodiment, the transmission component includes: a transmission frame 32, which is disposed on the second connecting shaft 31 and fixedly connected to the second connecting shaft 31; a transmission block 33, which is fixedly connected to the transmission frame 32; and a transmission rod 34, which is fixedly connected to the transmission block 33.

[0078] This configuration ensures that when the rotating cylinder 27 contacts the transmission block 33, it drives the transmission block 33 to move away from the rotating cylinder 27, causing the transmission rod 34, which is fixedly connected to the transmission block 33, to move closer to the support barrel 1, thereby vibrating the support barrel 1.

[0079] Working principle: In use, first start the drive motor 8, which drives the drive shaft 9, which is detachably fixed to the output end of the drive motor 8, to rotate. This causes the crushing blade 10, which is fixed to the drive shaft 9, to rotate. Then, the fiber to be crushed is put into the support barrel 1 through the feed port 5 for crushing. Then, start the vibration motor 21, which drives the vibration shaft 22, which is detachably fixed to the output end of the vibration motor 21, to rotate. This causes the first rotating plate 23, which is fixed to the vibration shaft 22, to rotate. This causes the second rotating plate 25, which is fixed to the first rotating shaft 24, to rotate. This causes the second rotating shaft 26, which is fixed to the second rotating plate 25, to rotate on the second vibration plate 19. This causes the rotating cylinder 27, which is fixed to the first rotating shaft 24, to rotate. When the rotating cylinder 27 contacts the transmission block 33, it causes the transmission block 33 to move away from the rotating cylinder 27. This causes the transmission rod 34, which is fixed to the transmission block 33, to move closer to the support barrel 1. This causes the connecting plate 30, which is rotatably connected to the second connecting shaft 31, to rotate around the axis of the first connecting shaft 29, which is fixed to the connecting frame 28. This causes the support barrel 1 to vibrate.

[0080] After crushing is completed, the cleaning motor 12 is started, which drives the cleaning shaft 13, which is detachably and fixedly connected to the output end of the cleaning motor 12, to rotate. This causes the sliding ring 17, which is rotatably connected to the cleaning shaft 13, to rotate, thereby driving the sliding block to slide on the first sliding rod 14, the second sliding rod 15, and the third sliding rod 16, thereby cleaning the inner wall of the support barrel 1.

[0081] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
