Description

Technical Field

[0001] The utility model relates to a skin grinding machine, in particular to a skin grinding machine for the surface of bark-type medicinal materials, and belongs to the technical field of medicinal material processing machinery. Background Art

[0002] Medicinal plants such as cinnamon, phellodendron, eucommia bark, and magnolia bark are processed with their bark when they are prepared into medicinal materials. During processing, the surface of the collected bark needs to be cleaned to remove dirt and impurities such as dry old skin and dead skin attached to the surface of the bark, and retain the inner layer of the bark as a medicinal product. The traditional method of cleaning the surface of the bark is to use manual scraping, that is, the collected bark is flattened on the table or buckled on the inclined cylindrical rod, and then the surface of the bark is manually scraped with a scraper, wire brush, or steel ball. However, the manual scraping operation cannot guarantee the stability of product quality due to the different strengths and depths of scraping for each person. In addition, the manual hanging grinding operation has high labor intensity and low processing efficiency, which cannot meet the needs of mass production. Therefore, the market is in urgent need of a bark surface scraping equipment with higher processing efficiency and more stable processing quality to replace the manual scraping operation. Utility Model Content

[0003] The utility model aims to provide a bark medicinal material surface grinding machine, which is used for scraping and grinding the bark surface of bark medicinal materials such as cinnamon bark, phellodendron chinense, eucommia bark, and magnolia bark, so as to obtain higher processing efficiency and better processing quality than manual scraping operation.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A bark medicinal material surface grinding machine is provided with a frame, a lower supporting assembly with floating support is arranged in the middle and lower part of the frame, and an upper brush roller assembly is fixedly arranged above the lower supporting assembly in the frame.

[0006] The lower supporting assembly is provided with a horizontally arranged lower frame, and a horizontal transverse annular conveyor belt is supported by horizontally longitudinally arranged active rollers and driven rollers at the left and right ends above the lower frame. More than one horizontal longitudinal intermediate roller is arranged between the active roller and the driven roller in the annular conveyor belt to support the intermediate belt surface of the annular conveyor belt. A lower driving motor is arranged below the lower frame, and the active roller is driven to rotate by the lower driving motor through a chain transmission assembly, so that the upper belt surface of the annular conveyor belt is transported from right to left. A group of upwardly supported elastic support assemblies are provided at the lower part of the frame to elastically float the bottom surface of the lower frame.

[0007] The upper brush roller assembly is provided with a horizontally arranged upper frame, the upper frame is fixedly connected to the upper part of the frame, and a horizontal longitudinal upper roller brush is arranged below the upper frame at a position just above each intermediate roller of the corresponding lower supporting assembly, and the left and right sides of each upper roller brush are equipped with upper pressure rollers that elastically press against the upper belt surface of the endless conveyor belt, and the upper pressure roller and the upper belt surface of the endless conveyor belt together form a right-in and left-out material clamping and conveying channel; an upper driving motor is respectively arranged above the upper frame for each upper roller brush, and each upper driving motor drives the corresponding upper roller brush to rotate through the belt transmission assembly; the four corners of the bottom surface of the upper frame are also respectively provided with downwardly extending and adjustable downward extension length limit rods at positions corresponding to the frame of the lower frame, and under the elastic push of the elastic support assembly, the lower frame elastically presses upward against the lower end of the limit rod, thereby limiting the distance between the lower brush surface of the upper roller brush and the upper belt surface of the endless conveyor belt, thereby controlling the grinding depth.

[0008] The utility model uses an upper pressure roller and an annular conveyor belt to clamp and convey the bark material. While conveying, the upper roller brush scrapes the upper surface of the bark material to remove impurities on the surface of the bark material. Due to the mechanized processing, this machine can obtain higher processing efficiency and better processing quality than manual scraping and grinding operations. Since the lower support component adopts an elastic floating support, the annular conveyor belt can adaptively float up and down according to the thickness of the bark material when the machine clamps and conveys the bark material, and can achieve clamping and conveying of bark materials of different thicknesses. Since a limit rod with an adjustable extension length is provided between the fixed upper frame and the floating lower frame for limiting, the machine can limit the grinding depth of the upper roller brush on the surface of the bark material by adjusting the downward extension length of the limit rod. When the outer part of the upper roller brush is worn, the original grinding depth can be maintained by reducing the downward extension length of the limit rod, thereby extending the service life of the upper roller brush.
