Description

Technical Field

[0001] This invention belongs to the field of synthetic leather processing technology, and particularly relates to a discharge device and discharge process for a rotating impact synthetic leather spinning process. Background Technology

[0002] Synthetic leather nascent fibers are typically produced using a specific spinning process, where polymer streams solidify and take shape in a spinning mill. The main constituent materials are microfiber and polyurethane. In the manufacturing process, the raw materials are first heated to a molten state or placed in a suitable liquid state. These molten or liquid materials are then fed into a melt spinning machine. During the material transport process, some materials often accumulate, clogging the openings of the mesh cover. This obstructs the flow of materials, requiring periodic cleaning of the mesh cover. However, this significantly impacts operational efficiency, as the constant disassembly, cleaning, and reassembly is time-consuming and labor-intensive. Therefore, it is necessary to upgrade the existing operating structure to improve its ability to handle clod materials. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the present invention provides a convenient, efficient, and automated discharge device and discharge process for rotating impact synthetic leather spinning, capable of automatically handling blocky raw materials clogging the mesh cover.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A rotary impact-type discharge device for synthetic leather spinning includes a positioning box, a side drive device, a feed pipe, a rotary feed hood, a drive shaft, a first mesh cover, a second mesh cover, and an airflow impact hood. A rotary feed hood is installed in the center of the positioning box. The first and second mesh covers are respectively connected to the upper and lower sides of the rotary feed hood. The feed pipe is installed through one side of the positioning box. The inner end of the feed pipe passes through the middle of one side of the rotary feed hood to allow material flow. One side of the rotary feed hood is rotatably and sealingly connected to the inner end of the feed pipe. The airflow impact hood is installed inside the upper part of the positioning box. A drive shaft is installed in the middle of the other side of the rotary feed hood. The side drive device is installed on the other side of the positioning box. The side drive device controls the rotary feed hood to rotate periodically via the drive shaft, causing the first and second mesh covers to interchange positions, allowing them to alternately enter the airflow impact hood for airflow impact brushing.

[0005] Furthermore, the side drive device includes a side positioning cover, a rotating motor, a drive disc, a driven disc, and a transmission belt; the side positioning cover is installed on the outside of the other side of the positioning box and forms a drive cavity with the positioning box; the outer end of the drive shaft extends into the drive cavity; the driven disc is installed on the outer end of the drive shaft; the rotating motor is installed on the inside of the side positioning cover, and the rotating motor is connected to the drive disc through a power shaft; the drive disc and the driven disc are connected by a transmission belt.

[0006] Furthermore, the outer end of the drive shaft is rotatably engaged with the inner middle of the side positioning cover via a rotating locking block.

[0007] Furthermore, the rotating material passage hood has a material passage chamber inside; the rotating material passage hood has guide holes on its upper and lower sides respectively, and the material passage chamber is connected to the first mesh cover and the second mesh cover through the guide holes; the inner end of the feeding pipe is connected to the material passage chamber.

[0008] Furthermore, the upper end of the airflow impact shroud is provided with an air inlet pipe, the upper end of which is connected and fixed to the upper end of the positioning box. An exhaust pump and a filter box are provided on the air inlet pipe; the exhaust pump and the filter box are installed on the upper exterior of the positioning box.

[0009] Furthermore, multiple air inlet pipes are evenly distributed on both sides and the top of the airflow impact shroud.

[0010] Furthermore, the first mesh cover, the rotating material passage cover, and the second mesh cover are joined together to form a circular outline.

[0011] Furthermore, a discharge cover is provided in the middle of the bottom of the positioning box; the discharge cover is equipped with an opening and closing valve.

[0012] A discharge process for a rotary impact-type synthetic leather spinning discharge device includes the following steps: Raw materials are fed through a feed pipe into a rotary feed hood, which then guides the material through guide holes on its lower side. Finally, the material is discharged through a second mesh screen on the lower side of the rotary feed hood. When the mesh of the second mesh screen becomes clogged with lumpy material, causing obstructed material output, a side-drive device controls the rotary feed hood to rotate, swapping the positions of the first and second mesh screens. The material then passes through the lower first mesh screen for further filtering, while the second mesh screen rotates to the upper side and enters an airflow impact hood for airflow impact brushing. This causes the lumpy material clogged in the second mesh screen to be discharged downwards by the airflow impact. The lumpy material is crushed by the impact, which simultaneously restores the flow of the second mesh cover. After the first mesh cover has been filtering the material for a period of time, its mesh becomes clogged with lumpy material. The side drive device controls the rotation of the material passage cover, causing the first and second mesh covers to switch positions. In this way, the material continues to pass through the second mesh cover, which rotates to the lower side, while the first mesh cover rotates to the upper side and enters the airflow impact cover for airflow impact brushing. This causes the lumpy material clogged in the mesh of the first mesh cover to be discharged downward by the impact of the airflow, crushing the lumpy material and restoring the flow of the first mesh cover. This process is repeated, with the side drive device controlling the rotation of the material passage cover periodically via the drive shaft, allowing the first and second mesh covers to alternately pass through during operation.

[0013] The beneficial effects of this invention are as follows: When the mesh of the second mesh cover of this invention is blocked by lumpy raw materials, causing the raw material output to be obstructed, the rotating material passage cover is controlled by the side drive device to rotate, and the positions of the first and second mesh covers are swapped. In this way, the raw material continues to pass through the first mesh cover, which rotates to the lower side, while the second mesh cover rotates to the upper side and enters the airflow impact cover for airflow impact brushing. This causes the lumpy raw material blocked in the mesh of the second mesh cover to be discharged downward by the impact of the airflow, and the lumpy raw material is broken up by the impact, while the second mesh cover is restored to unobstructed flow. When the mesh of the first mesh cover is blocked by lumpy raw materials, the above process is repeated to swap the positions of the first and second mesh covers again, so that the first mesh cover rotates to the upper side and enters the airflow impact cover for airflow impact brushing. In this way, this invention controls the rotating material passage cover to rotate periodically through the side drive device via the drive shaft, so that the first and second mesh covers alternately pass through the rotating operation, which is convenient and efficient.

The feed pipe 3 is installed through one side of the positioning box 1. The inner end of the feed pipe 3 passes through the middle of one side of the rotary feed hood 4.

The side drive device 2 controls the rotating material passage cover 4 to rotate periodically through the drive shaft 5, and causes the first mesh cover 6 and the second mesh cover 7 to switch positions up and down, so that the first mesh cover 6 and the second mesh cover 7 alternately enter the airflow impact cover 8 for airflow impact brushing.

[0021] like Figures 1 to 5 As shown, to facilitate rotational control of the drive shaft 5, the side drive device 2 further includes a side positioning cover 21, a rotating motor 22, a drive disc 23, a driven disc 24, and a transmission belt 25. The side positioning cover 21 is installed on the outside of the other side of the positioning housing 1, forming a drive cavity 11 with the positioning housing 1. The outer end of the drive shaft 5 extends into the drive cavity 11. The driven disc 24 is installed on the outer end of the drive shaft 5. The rotating motor 22 is installed on the inner side of the side positioning cover 21, and the rotating motor 22 is connected to the drive disc 23 through a power shaft 221. The drive disc 23 and the driven disc 24 are connected by a transmission belt 25. Furthermore, the outer end of the drive shaft 5 is rotatably engaged with the middle of the inner side of the side positioning cover 21 by a rotating locking block 51.

[0022] like Figures 1 to 5As shown, in order to facilitate the connection between the rotating material passage cover 4 and the first mesh cover 6 and the second mesh cover 7, the rotating material passage cover 4 is further provided with a material passage cavity 41 inside; the upper and lower sides of the rotating material passage cover 4 are respectively provided with material guide holes 42, and the material passage cavity 41 is connected to the first mesh cover 6 and the second mesh cover 7 through the material guide holes 42; the inner end of the feed pipe 3 is connected to the material passage cavity 41.

[0023] like Figures 1 to 5 As shown, to facilitate airflow discharge from the airflow impact shroud 8, an air inlet pipe 81 is further provided at the upper end of the airflow impact shroud 8. The upper end of the air inlet pipe 81 is connected and fixed to the upper end of the positioning box 1. An exhaust pump 82 and a filter box 83 are provided on the air inlet pipe 81; the exhaust pump 82 and the filter box 83 are installed on the upper exterior of the positioning box 1. Furthermore, multiple air inlet pipe heads 84 are evenly distributed on both sides and the upper side of the airflow impact shroud 8. Furthermore, the first mesh cover 6, the rotating material passage cover 4, and the second mesh cover 7 are joined to form a circular outline. To facilitate the conveying of raw materials, a discharge cover 9 is further provided in the middle of the bottom of the positioning box 1; the discharge cover 9 is provided with an opening and closing valve 91.

[0024] like Figures 1 to 5 As shown, the discharge process of a discharge device for a rotating impact type synthetic leather spinning process includes the following steps: Raw materials are input through the feed pipe 3 and enter the rotating feed hood 4. The raw materials are guided through the guide holes 42 on the lower side of the rotating feed hood 4. Finally, the raw materials are filtered and discharged through the second mesh cover 7 on the lower side of the rotating feed hood 4. When the mesh of the second mesh cover 7 is blocked by lumpy raw materials, causing uneven material output, the rotating feed hood 4 is rotated via the drive shaft 5 through the side drive device 2, causing the first mesh cover 6 and the second mesh cover 7 to swap positions. The raw materials continue to be filtered and discharged through the first mesh cover 6, which rotates to the lower side, while the second mesh cover 7 rotates to the upper side and enters the airflow impact cover 8 for airflow impact brushing. This causes the lumpy raw materials blocked in the mesh of the second mesh cover 7 to be discharged downwards by the impact of the airflow. The material is discharged, and the impact breaks up the lumpy material, while simultaneously restoring the unobstructed flow of the second mesh cover 7. After the first mesh cover 6 has been filtering the material for a period of time, its mesh becomes clogged with lumpy material. The side drive device 2 controls the rotation of the material passage cover 4 via the drive shaft 5, causing the first mesh cover 6 and the second mesh cover 7 to switch positions. In this way, the material continues to pass through the second mesh cover 7, which has rotated to the lower side, while the first mesh cover 6 rotates to the upper side and enters the airflow impact cover 8 for airflow impact brushing. This causes the lumpy material clogged in the mesh of the first mesh cover 6 to be discharged downwards by the impact of the airflow, breaking up the lumpy material and restoring the unobstructed flow of the first mesh cover 6. This process is repeated, with the side drive device 2 controlling the rotation of the material passage cover 4 periodically via the drive shaft 5, causing the first mesh cover 6 and the second mesh cover 7 to alternately pass through during rotation.

[0025] When the mesh of the second mesh cover 7 of this invention is blocked by lumpy raw materials, causing the raw material output to be obstructed, the side drive device 2 controls the rotation of the material passage cover 4 via the drive shaft 5, thereby causing the first mesh cover 6 and the second mesh cover 7 to switch positions vertically. In this way, the raw material continues to pass through the first mesh cover 6, which rotates to the lower side, while the second mesh cover 7 rotates to the upper side and enters the airflow impact cover 8 for airflow impact brushing. This causes the lumpy raw materials blocked in the mesh of the second mesh cover 7 to be discharged downward by the impact of the airflow, and the lumpy raw materials are broken up by the impact, while the second mesh cover 7 is restored to unobstructed flow. When the mesh of the first mesh cover 6 is blocked by lumpy raw materials, the above process is repeated to switch the positions of the first mesh cover 6 and the second mesh cover 7 again, so that the first mesh cover 6 rotates to the upper side and enters the airflow impact cover 8 for airflow impact brushing. In this way, the present invention controls the rotation of the material passage cover 4 periodically via the drive shaft through the side drive device 2, so that the first mesh cover 6 and the second mesh cover 7 alternately pass through the rotating operation, which is convenient and efficient.
