Description

Technical Field

[0001] The utility model relates to a coffee machine accessory, specifically a coffee powder anti-blocking powder discharging mechanism. Background Technique

[0002] As an important part of modern coffee machines, coffee grinders play a crucial role in the coffee-making process. Traditional coffee grinders usually include a grinding mechanism and a powder discharging mechanism. The coffee beans are ground into powder by the grinding mechanism, and the coffee powder is conveyed to a designated position by the powder discharging mechanism. However, in the prior art, the problem of blockage often occurs during the powder discharging process of coffee powder, which affects the normal operation of the coffee machine and the uniform powder discharging of coffee powder.

[0003] The existing powder discharging mechanism of coffee grinders usually directly drops the ground coffee powder into the powder discharging pipe by gravity. However, due to the fineness of coffee powder particles and the electrostatic effect, the coffee powder is likely to aggregate in the powder discharging pipe, resulting in blockage. This kind of blockage not only affects the powder discharging speed of coffee powder, but also may cause uneven powder discharging, affecting the taste quality of coffee. In addition, common anti-blocking devices such as vibrators or air ejectors in the prior art can alleviate the blockage problem to a certain extent, but their structures are complex, energy consumption is high, and they are easy to wear, affecting the durability of the equipment and the maintenance cost. Therefore, it is necessary to make further improvements to it. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a coffee powder anti-blocking powder discharging mechanism with a simple structure, convenient use, which can effectively improve the powder discharging efficiency and powder discharging accuracy of the coffee grinder.

[0005] The purpose of the utility model is realized in the following way: a coffee powder anti-blocking powder discharging mechanism, which includes a powder discharging pipe connected to the grinding mechanism. The powder discharging pipe is communicated with a powder falling port on the side wall of the powder discharging pipe. The coffee powder enters the powder discharging pipe through the powder discharging pipe and the powder falling port, and drops from the bottom of the powder discharging pipe to realize powder discharging.

[0006] A sealing piston is installed in the powder discharging pipe, and the sealing piston moves up and down under the drive of a power mechanism. When the power mechanism drives the sealing piston to move below the powder falling port, the powder discharging function is closed. When the power mechanism drives the sealing piston to move above the powder falling port, the powder discharging function is opened.

[0007] Furthermore: an avoidance groove is arranged on the cylindrical surface of the powder discharging pipe, and a connecting rod is arranged on the side wall of the sealing piston. The connecting rod passes through the avoidance groove and is connected to the power mechanism.

[0008] Further: The power mechanism includes a reduction motor, which is connected with a driving disc; it also includes a guide rod, on the surface of which a driving arm is slidably sleeved up and down. A driving column is arranged on the driving disc and extends into the driving arm. When the driving disc rotates, the driving arm is driven by the driving column to move up and down along the direction of the guide rod, and the sealing piston is connected with the driving arm.

[0009] Further: A boss is arranged on the driving disc. Correspondingly, a position switch is installed outside the driving disc. When the driving disc rotates to a set angle, the boss presses the position switch to generate an electric control signal.

[0010] Further: At least two guide rods are provided, and the two are installed in parallel. Sliding sleeves are arranged at both ends of the driving arm, and the sliding sleeves are sleeved outside the guide rods and connected with them.

[0011] Further: A guide groove is transversely arranged on the driving arm, and the driving column extends into the guide groove and slides therein.

[0012] Further: The upper and lower ends of the guide rod are fixed on a bracket, and the reduction motor and the powder outlet pipe are both fixed on the bracket.

[0013] The beneficial effects of the present utility model are as follows: 1. The structure is simple, the production cost is low, and the market competitiveness is improved.

[0014] 2. By arranging a sealing piston in the blanking pipe and using the power mechanism to drive the sealing piston to move up and down, the present utility model can effectively prevent the accumulation and blockage of coffee powder in the blanking pipe. When the sealing piston moves above the powder dropping port, the powder dropping function is turned on to enable the coffee powder to be smoothly discharged; when the sealing piston moves below the powder dropping port, the powder dropping function is turned off, thus avoiding the blockage problem caused by the coffee powder staying in the blanking pipe for a long time and ensuring the smoothness and continuity of the powder dropping process.

[0015] 3. The powder dropping mechanism of the present utility model is designed simply and clearly. It adopts a direct driving mode of the sealing piston and the power mechanism, with fewer structural components, high reliability, and more convenient maintenance. The cooperative design of the connecting rod, guide rod, and driving arm in the driving mechanism makes the system operate more stably, reducing the risk of failures that may be brought by a complex structure. In addition, the maintenance and cleaning of the equipment are more convenient, reducing the operating cost.

[0016] 4. The powder dropping mechanism of the present utility model adopts an automated design. By driving the sealing piston to move through a reduction motor, it realizes the automatic anti-blocking and discharging of coffee powder, reduces manual intervention, and improves the operation convenience. Especially in the process of mass production, this technology can significantly improve the production efficiency, reduce the downtime caused by blockage, and ensure the continuity and stability of the production process.

[0024] The following further specifically describes the present utility model with reference to the accompanying drawings. A coffee grinding anti-blocking powder feeding mechanism includes a powder discharging pipe 2 connected to a grinding mechanism 1. The powder discharging pipe 2 communicates with a powder falling port 31 on the side wall of a feeding pipe 3. Coffee powder enters the feeding pipe 3 through the powder discharging pipe 2 and the powder falling port 31 and drops from the bottom of the feeding pipe 3 to achieve powder feeding.

[0025] A sealing piston 4 is installed in the feeding pipe 3. The sealing piston 4 moves up and down under the drive of a power mechanism. When the power mechanism drives the sealing piston 4 to move below the powder falling port 31, the powder feeding function is closed. When the power mechanism drives the sealing piston 4 to move above the powder falling port 31, the powder feeding function is opened.

[0026] In one embodiment: an avoidance groove 32 is provided on the cylindrical surface of the feeding pipe 3. A connecting rod 41 is provided on the side wall of the sealing piston 4. The connecting rod 41 passes through the avoidance groove 32 and is connected to the power mechanism.

[0027] In one embodiment: the power mechanism includes a reduction motor 5. The reduction motor 5 is connected with a driving disc 6. A guide rod 7 is further included. A driving arm 8 is slidably sleeved on the surface of the guide rod 7 up and down. A driving column 61 is provided on the driving disc 6 and extends into the driving arm 8. When the driving disc 6 rotates, the driving arm 8 is driven to move up and down along the direction of the guide rod 7 through the driving column 61. The sealing piston 4 is connected with the driving arm 8.

[0028] In one embodiment, a boss 62 is provided on the driving disk 6, and correspondingly, a position switch 63 is installed outside the driving disk 6. When the driving disk 6 rotates to a set angle, the boss 62 presses the position switch 63 to generate an electric control signal.

[0029] In one embodiment, at least two guide rods 7 are provided, which are installed in parallel. Slide sleeves 81 are provided at both ends of the driving arm 8 , and the slide sleeves 81 are sleeved outside the guide rod 7 and connected thereto.

[0030] In one embodiment, a guide groove 82 is transversely arranged on the driving arm 8, and the driving column 61 extends into the guide groove 82 and slides.

[0031] In one embodiment, the upper and lower ends of the guide rod 7 are fixed on the bracket 9 , and the reduction motor 5 and the powder outlet pipe 2 are both fixed on the bracket 9 .

[0032] Working principle: After the coffee beans are ground into powder by the grinding mechanism 1, the coffee powder is first transferred to the feeding pipe 3 through the powder outlet pipe 2 connected to the grinding mechanism 1. The powder outlet pipe 2 is connected to the powder outlet 31 on the side wall of the feeding pipe 3. The coffee powder enters the feeding pipe 3 through the powder outlet pipe 2 and the powder outlet 31, and is finally discharged from the bottom of the feeding pipe 3 to a designated position.

[0033] In order to prevent coffee powder from accumulating in the feeding tube 3 and causing clogging, the utility model designs a sealing piston 4, which is installed in the feeding tube 3 and can move up and down along the feeding tube 3 under the drive of the power mechanism. When the power mechanism drives the sealing piston 4 to move below the powder drop port 31, the sealing piston 4 closes the powder drop port 31 to prevent the coffee powder from continuing to be dropped; and when the sealing piston 4 moves above the powder drop port 31, the powder drop port 31 is opened, and the coffee powder can be dropped smoothly. Among them, when the piston moves, the piston and the inner wall of the powder drop tube are scraped, thereby avoiding the accumulation of powder in the pipeline and effectively preventing clogging.

[0034] It should be noted that the core components of the power mechanism in this case are the reduction motor 5 and the drive disc 6 connected thereto. When the reduction motor 5 is started, the drive disc 6 starts to rotate, and a drive column 61 is provided on the drive disc 6, and the drive column 61 extends into the guide groove 82 in the drive arm 8. As the drive disc 6 rotates, the drive column 61 slides up and down along the guide groove 82, thereby driving the drive arm 8 mounted on the guide rod 7 to move up and down.

[0035] The driving arm 8 is connected to the sealing piston 4 through the connecting rod 41. The up-and-down movement of the driving arm 8 directly drives the sealing piston 4 to move up and down in the blanking pipe 3, realizing the opening and closing of the powder falling port 31. Since the rotation of the driving disk 6 is controlled by the reduction motor 5, the movement of the sealing piston 4 has precise controllability, so that the blanking amount and blanking time of the coffee powder can be accurately adjusted according to requirements.

[0036] In order to ensure the movement stability of the driving arm 8, the present utility model designs at least two parallel guide rods 7. The sliding sleeves 81 are installed at both ends of the driving arm 8. The sliding sleeves 81 are sleeved outside the guide rods 7 and connected thereto, ensuring the smooth up-and-down sliding of the driving arm 8. This design not only enhances the stability of the system, but also extends the service life of the equipment.

[0037] In addition, in order to further improve the precise control ability of the system, the present utility model is provided with a boss 62 on the driving disk 6. When the driving disk 6 rotates to a set angle, the boss 62 presses the position switch 63 to generate an electric control signal, thereby realizing the automatic control and feedback of the driving mechanism. This design makes the whole powder feeding process more intelligent and ensures the stability of the equipment operation.

[0038] Compared with the traditional technology, when working through the sealing piston in this case, it moves axially in the blanking pipe, which can effectively scrape the coffee powder accumulated in the blanking pipe, solves the problem of easy blockage of the traditional blanking mechanism, and ensures the smooth blanking of the coffee powder. At the same time, the precise cooperation between the sealing piston and the power mechanism makes the blanking process highly controllable, and the blanking amount and time of the coffee powder can be accurately adjusted according to needs, reducing waste.

[0039] In summary, the working principle of the present utility model is reasonable and efficient. Through the innovative design of key components, the blockage problem in the blanking process of the coffee grinder is significantly improved. At the same time, it has significant advantages in energy saving, control accuracy and operation convenience, so it can be widely promoted and used.

[0040] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
