Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning brushes, and more specifically to a centrifugal cleaning machine for cleaning brushes. Background Technology
[0002] In high-precision cleaning applications, such as medical device sterilization and optical lens maintenance, polyvinyl alcohol (PVA) water-soluble cleaning brushes stand out due to their biodegradable and environmentally friendly properties and zero-scratching characteristics. During the manufacturing process, starch granules are introduced as a key auxiliary material; their insoluble nature allows them to form a dispersed phase in the solution system. During the foaming stage, gas preferentially accumulates on the surface of the starch granules, thus constructing a uniform pore structure. Subsequent water washing dissolves and removes the starch, and the remaining cavities significantly improve the porosity and elasticity of the sponge, optimizing cleaning performance.
[0003] However, existing water washing processes have significant technical limitations. Due to the complex three-dimensional pore network within the cleaning brush sponge, this structure generates strong mass transfer resistance, making it difficult for water to penetrate deeply and fully contact the starch granules deep within the sponge. Therefore, traditional water washing methods struggle to completely remove starch residue, becoming a key bottleneck restricting product quality improvement. Utility Model Content
[0004] In view of the above, the purpose of this utility model is to provide a centrifugal cleaning machine for cleaning brushes, addressing the problems of the prior art.
[0005] The centrifugal cleaning machine for cleaning brushes in this solution is provided with a cleaning chamber, in which a drive end and a water inlet are arranged opposite to each other. Both ends of the cleaning brush product can be connected to the drive end and the water inlet. Water flows into the product from the water inlet and is thrown out to the outside of the product by centrifugal rotation.
[0006] Furthermore, the water inlet includes a pipe and a bearing installed in the pipe, with one end of the product inserted into the bearing.
[0007] Furthermore, the drive end includes a rotating shaft, and a servo motor is provided on the rotating shaft to drive its rotation.
[0008] Furthermore, the cleaning chamber is equipped with multiple workstations, each of which is equipped with a drive end and a water supply end.
[0009] Furthermore, the water inlet is movably mounted on the cleaning chamber.
[0010] Compared to existing technologies, this application utilizes centrifugal force to enable water flow to powerfully penetrate the complex three-dimensional pores of the sponge, breaking through the limitations of traditional water washing mass transfer resistance, achieving thorough removal of residual starch particles inside, and ensuring uniformity and thoroughness of cleaning.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Reference Figures 1 to 2 The centrifugal cleaning machine for cleaning brushes shown includes a cleaning chamber 1, inside which a drive end 2 and a water inlet 3 are arranged opposite each other. The cleaning brush can be inserted between the drive end 2 and the water inlet 3, and the two work together to achieve efficient cleaning. The drive end 2 includes a rotating shaft, and a servo motor 4 is arranged outside the cleaning chamber 1. The servo motor 4 is connected to the rotating shaft via a chain. The rotating shaft is designed with a plug-in end that matches the cleaning brush, allowing the brush to be inserted and stably positioned. When the servo motor 4 starts, power is transmitted to the rotating shaft via the chain, causing the cleaning brush to rotate at high speed. The water inlet 3 includes a pipe 301 and a bearing 302. The pipe 301 is the water delivery channel, and the internal bearing 302 plays a crucial role. After one end of the cleaning brush is inserted into the bearing 302, it can rotate freely without affecting the water flow through the pipe 301, ensuring smooth water flow into the brush. In practical applications, the water inlet 3 is movably installed in the cleaning chamber 1 using a plug-in connection method for easy loading and unloading of the brush. The stop structure installed at the inner end of the pipeline 301 prevents the pipeline 301 from accidentally detaching from the cleaning chamber 1, ensuring the safe operation of the equipment.
[0016] Work steps:
[0017] During operation, the water inlet end 3 is pulled apart from the drive end 2, and the cleaning brush is placed between them. Then, the water inlet end 3 is reset, so that the two clamp the cleaning brush together. After the servo motor 4 is started, it drives the cleaning brush to rotate at high speed. At the same time, water flows into the product from the pipe 301 of the water inlet end 3. Under the strong action of centrifugal force, the water is quickly thrown out to the outside of the product, forming an efficient rinsing cycle. This unique centrifugal rotation cleaning method breaks through the limitations of traditional water washing processes, allowing the water to fully contact every corner of the sponge's interior, thoroughly removing residual starch particles, achieving deep cleaning inside and outside the product, and ensuring the uniformity and thoroughness of the cleaning.
[0018] To further improve cleaning efficiency, cleaning chamber 1 adopts a multi-station design, with each station independently equipped with a drive end 2 and a water supply end 3. This means that one machine can clean multiple cleaning brush products simultaneously, significantly increasing cleaning efficiency and meeting the cleaning needs of large-scale production. The stations work independently yet collaboratively, greatly enhancing the practicality and economy of the equipment.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
