Description

Technical Field

[0001] This invention relates to the field of grinding equipment, specifically an automated grinding machine for producing Artemisia annua cakes. Background Technology

[0002] Watercress, also known as reed wormwood or watercress, is used to make watercress cakes. The process begins by selecting tender watercress stems and leaves, washing and blanching them. After blanching, the watercress is rinsed in cold water and squeezed dry. The stems and leaves are then processed into small pieces or a paste, which is mixed with glutinous rice flour and other ingredients to form a dough. The dough is then divided into several portions, pressed into cakes, and finally processed through frying to obtain edible watercress cakes. In existing technology, the watercress stems and leaves are squeezed dry and ground separately in two separate machines, and then transported by conveyor belt. This process requires multiple loading, unloading, and transfers, affecting processing efficiency and potentially leading to contamination of the watercress, thus compromising food hygiene. In addition, to fully release the aroma of the watercress and avoid the rough texture caused by excessively long stems and leaves, the watercress needs to be ground as finely and evenly as possible. Summary of the Invention

[0003] The purpose of this invention is to address the above problems by providing an automated grinding machine for the production of Artemisia annua cakes, which can optimize the transfer process of Artemisia annua and improve work efficiency; at the same time, it makes the particles of Artemisia annua stems and leaves after grinding more delicate and uniform.

[0004] To achieve the above objectives, the technical solution adopted in this application is: an automated grinding machine for producing Artemisia annua cakes, comprising a workbench, a storage cylinder above the workbench, and the storage cylinder being open at both ends; during operation, the storage cylinder sequentially passes through a feeding zone, a compression zone, and a processing zone, where the storage cylinder completes the addition of Artemisia annua, the extrusion of water, and the addition of Artemisia annua to the grinding mechanism, respectively; a compression plate is provided above the compression zone, moving axially along the storage cylinder; a discharge port is provided on the workbench at the processing zone; a grinding mechanism is provided below the discharge port; the grinding mechanism includes a housing, an inlet connected to the discharge port at the upper end of the housing, a cutting blade is provided inside the housing below the inlet, a grinding roller is provided inside the housing below the cutting blade, grinding teeth are provided on the outer side wall of the grinding roller, a grinding ring cooperating with the grinding teeth is provided on the inner side wall of the housing, and an outlet is provided below the grinding roller in the housing. The slitting blade breaks down and pre-cuts the wormwood, reducing the length of its stems and leaves and making them more uniform in length. This improves grinding efficiency and produces more uniform particles after grinding, thereby further enhancing the grinding quality.

[0005] Furthermore, to prevent water generated during the squeezing process from flowing out, a baffle is installed around the upper part of the workbench, outside the movement path of the storage cylinder. Additionally, a water collection trough is provided at the upper part of the workbench, connected to a drain pipe on the workbench. In this way, the water squeezed from the water collection trough can be collected and subsequently discharged through the drain pipe, thus ensuring a clean production environment.

[0006] Furthermore, the storage cylinder has drainage holes spaced apart on its side wall to facilitate the drainage of water from the wormwood.

[0007] Furthermore, to facilitate the addition of Artemisia leaves and stems to the storage cylinder, a feeding hopper is provided above the feeding area, and a vibrating motor is installed on the side wall of the feeding hopper. The vibrating motor drives the material in the feeding hopper to move downwards, thereby preventing Artemisia and other materials from getting stuck in the storage cylinder.

[0008] Furthermore, since the materials used are the stems and leaves of Gracilaria, which are mostly long and thin, a conveyor belt is horizontally installed above the feeding hopper to prevent material from getting stuck in the storage hopper and to provide suitable raw materials for subsequent grinding. At the end of the conveyor belt is an anvil, located directly above the feeding end of the hopper. Above the anvil is a reciprocating primary cutter used to cut the stems and leaves of Gracilaria into smaller segments.

[0009] Furthermore, a nozzle is provided on the inner wall of the housing, facing the grinding roller, and the grinding roller is cleaned by liquid or gas sprayed from the nozzle.

[0010] Furthermore, the grasses inside the storage cylinder are mostly long, branched strips that intertwine. A support rod, which automatically returns to a horizontal position, is hinged to the lower end of the storage cylinder's side wall. This support rod is arranged in a circular array around the cylinder's axis. During the cylinder's movement, the support rod provides support and constraint for the material inside, preventing it from getting stuck between the storage cylinder and the worktable, thus avoiding wear on the grasses. Since both excessively fast and slow feeding speeds affect the grinding quality and efficiency, the support rod ensures orderly feeding, preventing uncontrolled feeding once the storage cylinder reaches the discharge port.

[0011] Furthermore, since the material inside the storage cylinder consists mostly of intertwined stems and leaves, especially after being compressed by the compression plate, the wormwood is tightly packed together. Therefore, due to friction and the supporting structure formed by the intertwined stems and leaves, the wormwood is not easily allowed to fall downwards. To ensure that the wormwood in the storage cylinder can fall into the shell for grinding, a pusher plate is provided above the processing area. Driven by a pusher drive mechanism, the pusher plate moves axially along the storage cylinder, and the feeding speed is controlled by the cooperation of the pusher plate and the carrying rod.

[0012] Furthermore, to ensure the carrying rod can return to a horizontal position and avoid interference with the movement of the storage cylinder, an arc-shaped groove concentric with the discharge port is provided on the upper end of the discharge port sidewall. Grooves are arranged in a circular array around the discharge port axis on the discharge port sidewall, with the grooves positioned perpendicular to the discharge port axis. A spring is installed within each groove, with one end of the spring extending into the discharge port without external force. The position of the spring is adapted to the carrying rod.

[0013] Furthermore, to improve processing efficiency, the storage cylinders are arranged in a circular array around a rotating shaft. The rotating shaft rotates around its vertical axis under the drive of the main motor, and the rotating shaft is connected to the storage cylinders via connecting rods. In this way, different storage cylinders can perform feeding, extrusion, and discharging actions separately.

[0014] The beneficial effects of this application are as follows: The storage cylinder sequentially passes through the feeding zone, compression zone, and processing zone, realizing continuous processing of Gracilaria from raw material input to ground finished product. This optimizes the Gracilaria transfer process, avoiding the time and labor costs wasted during multiple feeding and unloading processes, and significantly improving production efficiency. Simultaneously, because the Gracilaria is stored inside the cylinder, its contact with the outside environment is reduced, thus improving food safety and hygiene to some extent. During the grinding process, the Gracilaria is first processed into small segments by a cutting blade before the grinding operation, resulting in more uniform material before grinding and contributing to finer and more uniform particles after grinding.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0021] Example 1, such as Figures 1-4 As shown, the specific structure of this embodiment is an automated grinding machine for producing Artemisia annua cakes, including a workbench 1. A storage cylinder 2 is arranged above the workbench 1, with the lower end of the storage cylinder 2 in contact with or close to the upper end of the workbench 1. Drainage holes 15 are spaced apart on the side wall of the storage cylinder 2. The storage cylinder 2 is open at both the top and bottom and is arranged vertically. During operation, the storage cylinder 2 can move laterally through the feeding area, compression area, and processing area in sequence. It should be noted here that the feeding area and compression area are... The areas and processing areas are named by the applicant based on the operations performed at the corresponding positions of the storage cylinders 2. In this embodiment, in order to further improve work efficiency, the storage cylinders 2 are arranged in a circular array around the rotating shaft 27, and the included angle between two adjacent storage cylinders 2 is ninety degrees. The rotating shaft 27 rotates around its vertical axis under the drive of the main motor 28. The rotating shaft 27 is connected to the storage cylinders 2 through the connecting rod 29, and two adjacent storage cylinders 2 are also connected through the arc-shaped rod. The rotating shaft 27 is coaxially arranged with the worktable 1.

[0022] A baffle 12 is provided on the outer side of the upper end of the workbench 1, and a water collection trough 13 is provided on the upper end of the workbench 1. The middle part of the water collection trough 13 is recessed and connected to the drain pipe 14 on the workbench 1.

[0023] Above the compression zone is a compression plate 3 that moves axially along the storage cylinder 2. The compression plate 3 moves under the drive of cylinders such as air cylinders and oil cylinders. The worktable 1 has a discharge port 4 at the processing area. Below the discharge port 4 is a grinding mechanism. The grinding mechanism includes a housing 5. The upper end of the housing 5 has a feed port 6 that communicates with the discharge port 4. Below the feed port 6 inside the housing 5 is a cutting blade 7. Below the cutting blade 7 inside the housing 5 is a grinding roller 8. The grinding roller 8 is narrow at the top and wide at the bottom. The upper end of the grinding roller 8 is an arc shape that extends upward from the middle. The grinding roller 8 is driven by a grinding motor inside the housing. The grinding motor is located inside a sealed shell. The sealed shell is fixed by a support beam inside the housing 5. Grinding teeth 9 are provided on the outer wall of the grinding roller 8. A grinding ring 10 that mates with the grinding teeth 9 is provided on the inner wall of the housing 5. Abrasive materials such as teeth are provided on the inner wall of the grinding ring 10. The housing 5 has a discharge port 11 below the grinding roller 8. The inner wall of the housing 5 is provided with nozzles 21 facing the grinding roller 8. The nozzles 21 are arranged in a ring array around the grinding roller 8. The nozzles 21 are connected to a water source or a gas source through the flow channel in the side wall of the housing 5. The liquid or gas sprayed by the nozzles 21 cleans the grinding roller 8.

[0024] The specific working process is as follows: Workers add the cooled water-treated stems and leaves of *Gnaphalium affine* to the storage cylinder 2 located in the feeding area. The storage cylinder 2 then moves to the compression area for draining. A compression plate 3 moves downwards into the storage cylinder 2 to press the *Gnaphalium affine*, squeezing out the water. After draining, the storage cylinder 2 moves to the processing area. The *Gnaphalium affine* in the storage cylinder 2 enters the shell 5 through the discharge port 4 and the feed port 6. Inside the shell 5, the *Gnaphalium affine* is first processed into small segments by a rotating cutting blade 7. Then, it enters the space between the grinding teeth 9 and the grinding ring 10 and is ground into powder or mud. Finally, it falls out from the discharge port 11. As one storage cylinder 2 passes through the feeding area, compression area, and processing area in sequence, the remaining storage cylinders 2 take their place.

[0025] To ensure safer and more hygienic food processing, the upper end of the baffle 12 is positioned at the lower end of the top plate. The storage cylinder 2 moves within the space enclosed by the top plate, the baffle 12, and the worktable 1. The top plate has through holes in the feeding area, compression area, and processing area to facilitate the entry of materials and the operation of the compression plate. When the top plate is installed, the main motor 28 is mounted on the upper end of the top plate.

[0026] Example 2, as Figure 1 , Figure 3 As shown, the other mechanisms and working processes in this embodiment are the same as in embodiment 1. However, in this embodiment, a feeding hopper 16 is provided above the feeding area, and a vibration motor 17 is provided on the side wall of the feeding hopper 16. The feeding hopper 16 is not directly connected to the top plate. The vibration generated by the vibration motor 17 causes the grass to move downward.

[0027] A conveyor belt 18 is horizontally arranged above the feeding hopper 16. An anvil 19 is arranged at the end of the conveyor belt 18. The anvil 19 is located above the feeding end of the feeding hopper 16. A primary cutter 20 is arranged above the anvil 19. The primary cutter 20 moves vertically under the drive of a cylinder, hydraulic cylinder, etc., to preliminarily cut the material so that the material can enter the storage cylinder more smoothly.

[0028] Example 3, as Figure 1 , Figure 2 As shown, the other mechanisms and working processes in this embodiment are the same as in Embodiment 1. However, in this embodiment, an installation groove is provided at the lower end of the side wall of the storage cylinder 2. The lower end of the installation groove and one end of the inner side of the storage cylinder 2 are open. The installation groove is connected to the carrying rod 22 by a torsion spring or the like. The upper end face of the installation groove and the carrying rod 22 can be magnetically connected. The carrying rod 22 can automatically return to a horizontal state under the action of the torsion spring or the like. The carrying rods 22 are arranged in a circular array around the axis of the storage cylinder 2. Since the stems and leaves of the wormwood are mostly intersecting, they support each other. In this way, multiple carrying rods can effectively prevent the wormwood from getting stuck in the gap between the storage cylinder 2 and the workbench 1.

[0029] A pusher plate 23 is provided above the processing area. Driven by a pusher drive mechanism 24, the pusher plate 23 moves axially along the storage cylinder 2. The pusher drive mechanism 24 can be an existing linear push mechanism such as a cylinder or hydraulic cylinder. The lower end face of the pusher plate 23 is arc-shaped, with the center of the arc facing upwards, to facilitate pushing the carrying rod 22. Simultaneously, the pusher plate 23 and the carrying rod 22 can be magnetically connected, so that when the pusher plate 23 rises, it can cause the carrying rod 22 to flip upwards, ensuring that the carrying rod 22 returns to a horizontal state.

[0030] The upper end of the side wall of the discharge port 4 is provided with a concentric arc-shaped groove 25, the center of which faces the inside of the storage cylinder 2. A transverse groove is also arranged in a circular array around the axis of the side wall of the discharge port 4, and a spring 26 is installed within the groove. Without external force, one end of the spring 26 extends into the discharge port 4, and the position of the spring 26 is adapted to the loading rod 22.

[0031] Specific working process: When the storage cylinder 2 moves above the discharge port 4, the wormwood cannot fall directly downwards due to the support of the carrying rod 22 and the interlacing of the stems and leaves. When the pusher plate 23 moves downwards under the drive of the pusher drive mechanism 24, it pushes the wormwood in the storage cylinder 2. After being pushed, the wormwood will push open the carrying rod 22 and move downwards. Since the wormwood has interlaced and piled up tightly after being pressed, it will not all fall from the storage cylinder 2 into the shell 5 for grinding at once. Instead, it is added into the shell 5 in a controlled and gradual manner as the pusher plate 23 moves, thereby avoiding too much or too little wormwood flowing out and ensuring the efficiency and quality of grinding.

[0032] After the Artemisia is pushed out, the pusher plate 23 moves upward. After the carrying rod 22 loses pressure, it flips upward to a horizontal state under the action of the torsion spring and the spring 26. At this time, the pusher plate 23 and the carrying rod 22 can be magnetically connected so that the pusher plate 23 can drive the carrying rod 22 to flip to a horizontal state. Even if the carrying rod 22 is not completely reset, when the storage cylinder 2 moves, the arc groove 25 will also drive the carrying rod 22 to flip to a horizontal state.
