Description

Technical Field

[0001] This utility model relates to the field of donkey-hide gelatin powdering technology, and in particular to an automatic powdering device for donkey-hide gelatin powder. Background Technology

[0002] Ejiao, a traditional Chinese medicine, is a gelatinous substance made from the hide of donkeys (Equidae genus). After soaking and removing the hair, it is boiled down to form gelatinous blocks. It is believed to have blood-nourishing, yin-nourishing, lung-moistening, and hemostatic effects. When processing Ejiao, it needs to be ground into powder for better absorption. Existing equipment may be inefficient at grinding Ejiao blocks, and the blades wear easily. Furthermore, the disassembly and installation process is cumbersome, hindering cleaning and maintenance. For example, Chinese patent disclosure "A Grinding Device for Ejiao Product Production" (application number: 202022166802.3) utilizes a combination of a crushing chamber and a grinding chamber. The raw Ejiao is first crushed inside the crushing chamber, then filtered through a screen, and finally flows into the grinding chamber through a conical guide block along the inner wall of the fixed outer shell. The grinding plate rotates synchronously with the rotating rod to grind the crushed Ejiao. However, this device has a compact overall structure, making disassembly and maintenance inconvenient. Additionally, it lacks a sieving function for the final powdered Ejiao, potentially leading to uneven powder fineness. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an automatic grinding device for donkey-hide gelatin powder. A motor drives a rotating shaft and blades to rotate, achieving efficient grinding of donkey-hide gelatin blocks.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model discloses an automatic powder grinding device for donkey-hide gelatin powder, comprising: a sealing cover 2 rotatably connected to the rear surface of an outer shell 1 via a hinge, the sealing cover 2 covering the upper surface of the outer shell 1; a sealing gasket 4 fixedly connected to the lower surface of the sealing cover 2; a positioning hole 11 provided inside the sealing gasket 4; a grinding cylinder 5 movably connected to the inner side wall of the outer shell 1; a filter hole 13 provided on the lower surface of the grinding cylinder 5; a protective shell 10 fixedly connected to the lower surface of the grinding cylinder 5; a motor 7 fixedly connected to the lower surface of the grinding cylinder 5; and the protective shell 10 covering the motor 7, both located on the lead screw. Above the filter screen 12, the output end of the motor 7 is fixedly connected to a rotating shaft 8. A blade 9 is fixedly connected to the side surface of the rotating shaft 8. The rotating shaft 8 passes through the lower surface of the crushing cylinder 5. The end of the rotating shaft 8 away from the motor 7 is located inside the positioning hole 11. The blade 9 and the rotating shaft 8 are located inside the crushing cylinder 5. A placement platform 6 is provided on the inner side wall of the outer shell 1. The crushing cylinder 5 is located on the upper surface of the placement platform 6. A limit strip 18 is provided on the inner side wall of the outer shell 1. A limit groove 17 is provided on the side surface of the crushing cylinder 5. The limit strip 18 is located inside the limit groove 17.

[0022] Specifically, the rear surface of the outer casing 1 of the device is rotatably connected to the sealing cover 2 via a hinge, allowing the sealing cover 2 to be easily opened or closed. The sealing gasket on the lower surface of the sealing cover ensures a sealing effect after closure. At the same time, the grinding cylinder 5 is movably connected to the inner side wall of the outer casing 1 through the cooperation of the limiting groove 17 on the side surface and the limiting strip 18 on the inner side wall of the outer casing 1, preventing it from moving. It is supported by the support platform 6 on the inner side wall of the outer casing 1 to ensure its stability during operation. The cooperation between the limiting groove 17 and the limiting strip 18 facilitates the disassembly and installation of the grinding cylinder 5. During operation, the donkey-hide gelatin to be ground is placed into the inside of the grinding cylinder 5 through the opened sealing cover 2, and the sealing cover 2 is closed. The motor 7 is turned on to provide rotational force to the rotating shaft 8, which is transmitted to the blade 9, so that the blade 9 grinds the donkey-hide gelatin. During this process, the filter holes 13 on the lower surface of the grinding cylinder 5 can filter the ground donkey-hide gelatin to the bottom of the grinding cylinder 5. Filtering during the grinding process reduces the wear of the blade 9 on the donkey-hide gelatin to be ground.

[0023] Reference Figure 1 , Figure 2 and Figure 3 A sealing door 3 is rotatably connected to the side surface of the outer shell 1 via a rotating shaft. A motor 15 is fixedly connected to the lower surface of the outer shell 1. A lead screw 16 is fixedly connected to the output end of the motor 15. The thread on the side surface of the lead screw 16 is located in the middle of the lead screw 16. A filter screen 12 is threadedly connected to the side surface of the lead screw 16. A base 14 is fixedly connected to the lower surface of the outer shell 1. The base 14 covers the motor 15. The lead screw 16 passes through the lower surface of the outer shell 1.

[0024] Specifically, the powdered donkey-hide gelatin falling below the crushing cylinder 5 will be on the upper surface of the filter screen 12. The starting motor 15 provides power to the lead screw 16, which transmits the power to the filter screen 12, causing it to move up and down along the axial direction of the lead screw 16. At the same time, the fine sieve holes of the filter screen 12 further sieve the powdered donkey-hide gelatin, thus distinguishing the fineness of the powdered donkey-hide gelatin. Finally, it is taken out by opening the sealing door 3.

[0025] Working Principle: First, the donkey-hide gelatin to be powdered is placed into the grinding cylinder 5 through the open sealing cap 2, and the sealing cap 2 is closed. Then, motor 7 is started, providing rotational force to the rotating shaft 8, which in turn transmits the force to the blades 9, causing the blades 9 to grind the donkey-hide gelatin into powder. During this process, the filter holes 13 on the lower surface of the grinding cylinder 5 filter the powdered donkey-hide gelatin to the bottom of the grinding cylinder 5. Next, motor 15 is started, providing power to the lead screw 16. The lead screw 16 transmits the power to the filter screen 12, causing it to move up and down along the axial direction of the lead screw 16. The filter screen 12 further sieves the powdered donkey-hide gelatin through its fine sieve holes, distinguishing the fineness of the powdered donkey-hide gelatin. Finally, after sieving is completed, the sealing door is opened, and the sieved donkey-hide gelatin powder is taken out.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
