Description

Technical Field

[0001] This utility model relates to the technical field of down processing equipment, specifically a down dust removal machine. Background Technology

[0002] In the down processing industry, down dust removal is a crucial process. Its purpose is to remove dust and impurities from the down, improving its quality and purity to meet the requirements of subsequent production and product use. As people's demands for the quality of down products continue to rise, higher standards are being set for the performance and effectiveness of down dust removal equipment. Currently, various down dust removal machines exist on the market, each employing different working principles to remove dust from the down. For example, some machines use a beating method, employing a beating rod to beat the down-filled bag, causing the dust to be expelled from the bag's pores, and then collected by a negative pressure fan. However, existing down dust removal machines still have certain shortcomings in practical use and require further improvement.

[0003] In the prior art, such as the down dust removal machine disclosed in the Chinese authorized patent (publication number: CN220468263U), the beater rod is driven by the drive wheel, driven wheel and connecting column to beat the two sides of the filter bag synchronously. Although this solves the problem of easy clogging of the filter screen, its core structure still relies on the static beating of the fixed filter bag. Since the filter bag is fixed and the beater rod acts on the same area for a long time, it is easy to cause local wear or even breakage of the filter bag, shortening its service life. The down in the static filter bag is easily accumulated at the bottom due to gravity. During beating, only the surface down participates in dust separation, and the dust removal effect of the deep down is poor, thus affecting the overall dust removal efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a down dust removal machine, which solves the problem of fixed cloth bags being inconvenient to use by using a rotatable cloth bag.

[0005] This utility model is achieved through the following technical solution: This utility model is a down feather dust removal machine, including a housing and a rotating component. The dust removal component is installed inside the housing, and a partition is installed inside the housing. An annular groove is opened in the partition, and a limit ring is fitted in the annular groove. A circular ring is installed in the inner ring of the limit ring, and a cloth bag is installed at the bottom of the circular ring. The rotating component consists of a worm wheel and a worm. The worm wheel meshes with the worm and is sleeved on the outer surface of the limit ring. A through hole is opened in the partition, and the worm is fitted in the through hole.

[0006] Furthermore, the side panel of the housing has perforations, and the end of the worm gear fits into the perforations.

[0007] Furthermore, a circular groove is provided on the partition plate, a disc is installed on the top of the groove, a feed inlet is provided inside the disc, and a feed pipe is installed inside the feed inlet.

[0008] Furthermore, a valve body is installed on the feed pipe, and an air pipe is connected to the valve body.

[0009] Furthermore, a sealing ring is provided at the connection between the feed pipe and the feed inlet.

[0010] Furthermore, the dust removal component consists of a rotating shaft and a beating block. The two ends of the rotating shaft are fitted onto the inner walls of both sides of the housing, and the beating block is mounted on the rotating shaft, contacting the filter bag.

[0011] This utility model has the following beneficial effects: This utility model features a rotatable cloth bag that, through a transmission structure consisting of a worm gear, worm, and a limiting ring, allows the bag to rotate slowly and continuously during dust removal. This ensures even distribution of the beating force, significantly extending the bag's service life. Furthermore, during rotation, the down feathers continuously tumble inside the bag, preventing them from accumulating at the bottom and ensuring that the deep down feathers fully participate in dust removal, resulting in more thorough dust removal. This invention seals the feed pipe with a valve body and an air pipe. The inflated valve body fits tightly against the inner wall of the feed pipe, and the sealing ring achieves a double seal, completely preventing down or dust from overflowing during beating. Furthermore, the air pump controls the inflation and deflation of the valve body, enabling automatic opening and closing during the feeding stage and improving production efficiency.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
