Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a grinding equipment for jujube kernels with adjustable coarseness. Background Technology

[0002] As a traditional Chinese medicine, jujube seed powder has a wide range of applications in Chinese medicine preparations and health products. However, different uses require different fineness of jujube seed powder. Traditional grinding equipment often cannot achieve flexible adjustment of fineness, and the grinding and sieving processes are separated, which is cumbersome and inefficient. Therefore, it is particularly important to develop a jujube seed grinding equipment with adjustable fineness and integrated grinding and sieving. Utility Model Content

[0003] The problem this application aims to solve is that traditional grinding equipment not only cannot flexibly adjust the fineness of jujube kernels, but also suffers from low efficiency due to the separation of the grinding and screening processes.

[0004] To solve the above-mentioned technical problems, this application provides a jujube kernel grinding equipment with adjustable coarseness and fineness, including a frame, a grinding component with selectable coarse or fine grinding mode arranged vertically inside the frame, a sieving component that performs sieving operation by rotation at the bottom of the grinding component, a discharge channel for guiding jujube kernel powder from the grinding component to the sieving component arranged inside the frame, and a motor that drives the grinding component and the sieving component to operate simultaneously by means of pulleys and belts arranged on one side of the outside of the frame.

[0005] Because the grinding equipment of this application is designed with grinding components and sieving components, the grinding components and sieving components work together to make the whole process of jujube kernels from entering the equipment to completing grinding and sieving efficient and smooth, which greatly improves the processing efficiency and solves the problem that the existing traditional grinding equipment not only cannot flexibly adjust the fineness of jujube kernels, but also has low efficiency due to the separation of grinding and sieving processes.

[0012] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0013] This application relates to a milling device for jujube kernels with adjustable coarseness, such as... Figure 1-5 As shown, the grinding equipment includes a frame 2 as the basic support structure. The internal space of the frame 2 is used to arrange the grinding component 5, the sieving component 6, and related channels. The grinding component 5 is vertically arranged inside the frame 2. This component is designed to allow for coarse or fine grinding, which can be adjusted by changing the number of grinding cycles of the jujube kernels. The sieving component 6 is horizontally placed at the bottom of the grinding component 5 and performs sieving by rotation. The screen can be replaced with screen plates of different aperture sizes as needed to adapt to different sieving requirements. The feed channel 18 is arranged inside the frame 2 to guide the jujube kernel powder through the grinding component 5. The powder falls onto the sieving component 6 to ensure a smooth connection between the grinding and sieving processes. A motor 1 is arranged on one side of the frame 2, which drives the grinding component 5 and the sieving component 6 to operate simultaneously through pulleys and belts, realizing the power integration and efficient operation of the equipment. The kernel hopper 3 and the residue hopper 4 are respectively arranged at the bottom of the frame 2 to receive the jujube kernel powder and residue obtained after sieving, which facilitates subsequent classification, collection and processing. Transparent PVC panels are arranged on the upper part of the frame 2 at the positions of the grinding component 5 and the sieving component 6, so that the operators can intuitively observe the grinding and sieving situation and adjust the equipment parameters or handle abnormal situations in a timely manner.

[0014] The grinding assembly 5 includes a feed roller 8, a baffle 9, a handle 10, and four grinding rollers, named first roller 7, second roller 11, third roller 12, and fourth roller 13. These rollers are arranged equidistantly within the frame 2, forming a continuous grinding channel. The first roller 7 and second roller 11 are inclined, with the angle between their center lines and the Y-axis (assumed to be the longitudinal centerline of the equipment) being 27-30°. This inclined arrangement facilitates the natural falling and uniform dispersion of the jujube kernels during the grinding process. The second roller 11 and third roller 12 are arranged vertically to ensure the vertical transmission of grinding force. To improve grinding efficiency, the third roller 12 and the fourth roller 13 are arranged horizontally to provide stable support and uniform grinding effect for the final grinding stage. The top of the frame 2 is equipped with a feed roller 8 to control the amount of material falling. The design of the feed roller 8 allows the jujube kernels to enter the grinding channel evenly and controllably. A baffle 9 that can rotate around the frame 2 is arranged on one side of the feed roller 8. The baffle 9 is used to adjust the entry path of the jujube kernels. A handle 10 that is spirally connected to the upper part of the frame 2 is arranged thereto. The handle 10 abuts against the baffle 9. The opening and closing state of the baffle 9 can be easily controlled by rotating the handle 10. The feed roller 8 has a separate motor 1 to drive its forward and reverse rotation, ensuring accurate control of the amount of material falling and flexible switching of the grinding mode.

[0015] When the baffle 9 is closed, the feed roller 8 is driven to reverse by a separate motor 1. At this time, the jujube kernels fall along the gap between the feed roller 8 and the frame 2, and are successively ground three times between the first roller 7 and the second roller 11, between the second roller 11 and the third roller 12, and between the third roller 12 and the fourth roller 13, to achieve fine grinding. This multiple grinding process can ensure that the jujube kernel powder reaches a finer particle size.

[0016] When the baffle 9 is opened, the feed roller 8 is driven to rotate forward by a separate motor 1. At this time, the jujube kernels fall directly between the third roller 12 and the fourth roller 13 through the path between the feed roller 8 and the baffle 9 for a coarse grinding operation. In this mode, the particle size of the jujube kernel powder is relatively coarse, which is suitable for processing scenarios where the particle size requirement is not high.

[0017] The sieving assembly 6 includes a shaft 17, a sieve cylinder 14, a support frame 16, and a lever 15. The shaft 17 is horizontally positioned at the bottom of the frame 2 and connected to it via a bearing seat. The bearing seat design ensures the stability and smooth operation of the shaft 17 during operation. The sieve cylinder 14 is concentrically fitted around the shaft 17. The sieve cylinder 14 has meshes of different apertures to accommodate different particle size sieving requirements. The sieve cylinder 14 can rotate with the shaft 17 to separate powder kernels from powder residue. The upper part of the shaft 17 is evenly and spaced along its axial direction, with the support frame 16 supporting the sieve cylinder 14 to ensure... It remains stable during rotation, while avoiding direct contact between the screen cylinder 14 and the shaft 17, reducing wear. The upper part of the shaft 17 is also evenly and spaced with levers 15. The levers 15 are designed to agitate the powder kernels and residues, promoting their rapid separation. The levers 15 are divided into straight levers and spiral structures. The straight levers 15 are simple and direct, and can effectively agitate the powder kernels and residues in the screen cylinder 14, allowing them to pass through the screen quickly. The spiral levers 15 have better stirring and separation effects, and can form a spiral material flow when the screen cylinder 14 rotates, further improving screening efficiency.

[0018] When the motor 1 drives the shaft 17 to rotate, the screen cylinder 14 rotates accordingly. The powder kernels and powder residues are propelled by the lever 15 inside the screen cylinder 14 and quickly pass through the screen. Powder kernels that fit the screen aperture fall into the powder kernel hopper 3 below, while larger powder residues are blocked by the screen and travel along the screen cylinder 14 until they fall into the powder residue hopper 4. By adjusting the screen aperture and the structure of the lever 15, different particle size screening requirements can be achieved to meet diverse processing needs.

[0019] In operation, the jujube kernels first enter the grinding assembly 5 through the feed roller 8. With the baffle 9 closed, the feed roller 8 reverses direction, causing the jujube kernels to fall through the gap between the feed roller 8 and the frame 2. They are then ground three times sequentially by the first roller 7, the second roller 11, the third roller 12, and the fourth roller 13 for fine grinding. With the baffle 9 open, the feed roller 8 rotates forward, and the jujube kernels fall directly between the third roller 12 and the fourth roller 13 for coarse grinding. Whether coarse or fine grinding, the ground material falls into the sieving assembly 6 below, ready for sieving. In operation, when the ground material falls into the screen cylinder 14, the motor 1 drives the shaft 17 to rotate, causing the screen cylinder 14 to rotate as well. The screen on the screen cylinder 14 has a specific aperture, which allows powder kernels that match the aperture size to pass through, while larger powder residues are blocked by the screen. The levers 15 are evenly and spaced on the shaft 17 and are divided into straight lever type and spiral type structures. They effectively agitate the material in the screen cylinder 14, promoting the rapid separation of powder kernels and powder residues. The powder kernels that pass through the screen fall into the powder kernel collection hopper below, while the powder residues remain in the screen cylinder 14 or fall into the powder residue collection hopper, thus realizing the screening of materials.
