Description

Technical Field

[0001] The invention relates to a coffee machine accessory, in particular to a coffee grinding and powder discharging mechanism to prevent blocking. Background Art

[0002] As an important component of modern coffee machines, coffee grinders play a vital role in the coffee making process. Traditional coffee grinders usually include a grinding mechanism and a feeding mechanism. The grinding mechanism grinds coffee beans into powder, and the feeding mechanism delivers the coffee powder to a designated location. However, in the prior art, the feeding process of coffee powder often causes blockage, which affects the normal operation of the coffee machine and the uniform feeding of coffee powder.

[0003] The discharge mechanism of the existing coffee grinder usually uses gravity to drop the ground coffee powder directly into the discharge pipe. However, due to the fineness of the coffee powder particles and the electrostatic effect, the coffee powder is prone to aggregation in the discharge pipe, which then causes blockage. This blockage not only affects the discharge speed of the coffee powder, but may also cause uneven discharge and affect the taste quality of the coffee. In addition, the anti-blocking devices such as vibrators or air ejectors commonly used in the prior art, although they can alleviate the blockage problem to a certain extent, have a complex structure, high energy consumption, and are easy to wear, affecting the durability and maintenance cost of the equipment. Therefore, it is necessary to make further improvements. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a coffee grinder anti-blocking powder feeding mechanism which has a simple structure, is easy to use, and can effectively improve the feeding efficiency and powder feeding accuracy of the coffee grinder.

[0005] The object of the present invention is achieved by the following methods: a coffee grinding and anti-blocking powder discharge mechanism, comprising a powder discharge pipe connected to the grinding mechanism, the powder discharge pipe is connected to a powder drop opening on the side wall of a discharge pipe, coffee powder enters the discharge pipe through the powder discharge pipe and the powder drop opening, and falls from the bottom of the discharge pipe to achieve powder discharge; A sealing piston is installed in the feeding pipe, and the sealing piston moves up and down under the drive of the power mechanism. When the power mechanism drives the sealing piston to move below the powder dropping port, the powder dropping function is closed, and when the power mechanism drives the sealing piston to move above the powder dropping port, the powder dropping function is opened.

[0006] Furthermore: a gas avoidance groove is arranged on the cylindrical surface of the discharge pipe, and a connecting rod is arranged on the side wall of the sealing piston, and the connecting rod passes through the gas avoidance groove and is connected to the power mechanism.

[0007] Furthermore: the power mechanism includes a reduction motor, which is connected to a drive disk; it also includes a guide rod, on the surface of which a drive arm is slidably mounted up and down, and a drive column is provided on the drive disk to extend into the drive arm. When the drive disk rotates, the drive arm is driven to move up and down along the direction of the guide rod through the drive column, and the sealing piston is connected to the drive arm.

[0008] Furthermore: a boss is provided on the driving disk, and correspondingly, a position switch is installed outside the driving disk. When the driving disk rotates to a set angle, the boss presses the position switch to generate an electric control signal.

[0009] Furthermore: at least two guide rods are provided, which are installed in parallel, and sliding sleeves are provided at both ends of the driving arm, and the sliding sleeves are sleeved outside the guide rods and connected thereto.

[0010] Furthermore: a guide groove is transversely arranged on the driving arm, and the driving column extends into the guide groove to slide.

[0011] Furthermore, the upper and lower ends of the guide rod are fixed on the bracket, and the reduction motor and the powder outlet pipe are fixed on the bracket.

[0012] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0013] 2. The present invention can effectively prevent coffee powder from gathering and clogging in the feeding tube by arranging a sealing piston in the feeding tube and using a power mechanism to drive the sealing piston to move up and down. When the sealing piston moves to above the powder drop opening, the powder drop function is turned on to allow the coffee powder to be dropped smoothly; when the sealing piston moves to below the powder drop opening, the powder drop function is turned off, thereby avoiding the clogging problem caused by the coffee powder staying in the feeding tube for a long time, and ensuring the smoothness and continuity of the powder drop process.

[0014] 3. The powder discharging mechanism of the present invention is concise and clear in design, and adopts a direct drive mode between the sealing piston and the power mechanism, with fewer structural parts, high reliability, and more convenient maintenance. The coordinated design of the connecting rod, guide rod and driving arm in the driving mechanism makes the system operation more stable, reducing the risk of failure caused by complex structure. In addition, the maintenance and cleaning of the equipment are also more convenient, reducing the operating cost.

[0015] 4. The powder feeding mechanism of the present invention adopts an automated design, and the sealing piston is driven by a reduction motor to achieve automatic anti-blocking and feeding of coffee powder, reducing manual intervention and improving the convenience of operation. Especially in the mass production process, this technology can significantly improve production efficiency, reduce downtime caused by blockage, and ensure the continuity and stability of the production process.

[0023] The present invention is further described in detail below with reference to the accompanying drawings. A coffee grinding and powder discharge mechanism that prevents blockage includes a powder discharge pipe 2 connected to a grinding mechanism 1, wherein the powder discharge pipe 2 is connected to a powder discharge port 31 on the side wall of a discharge pipe 3, and coffee powder enters the discharge pipe 3 through the powder discharge pipe 2 and the powder discharge port 31, and falls from the bottom of the discharge pipe 3, thereby achieving powder discharge; A sealing piston 4 is installed in the discharge pipe 3, and the sealing piston 4 moves up and down 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 powder drop function is closed. When the power mechanism drives the sealing piston 4 to move above the powder drop port 31, the powder drop function is opened.

[0024] In one embodiment, a gas avoidance groove 32 is provided on the cylindrical surface of the feed tube 3, and a connecting rod 41 is provided on the side wall of the sealing piston 4. The connecting rod 41 passes through the gas avoidance groove 32 and is connected to the power mechanism.

[0025] In one embodiment: the power mechanism includes a reduction motor 5, which is connected to a drive disk 6; it also includes a guide rod 7, on the surface of which a drive arm 8 is slidably mounted up and down, and a drive column 61 is provided on the drive disk 6 to extend into the drive arm 8. When the drive disk 6 rotates, the drive arm 8 is driven to move up and down along the guide rod 7 through the drive column 61, and the sealing piston 4 is connected to the drive arm 8.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 .

[0030] 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.

[0031] In order to prevent coffee powder from accumulating in the feeding tube 3 and causing clogging, the present invention 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 discharged; 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 discharged 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.

[0032] 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.

[0033] 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 feeding tube 3, thereby opening and closing the powder dropping 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 feeding amount and feeding time of the coffee powder can be accurately adjusted according to the demand.

[0034] In order to ensure the movement stability of the driving arm 8, the present invention designs at least two parallel installed guide rods 7, and slide sleeves 81 are installed at both ends of the driving arm 8. The slide 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 prolongs the service life of the equipment.

[0035] In addition, in order to further improve the precise control capability of the system, the present invention sets 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 automatic control and feedback of the driving mechanism. This design makes the entire powder feeding process more intelligent and ensures the stability of the equipment operation.

[0036] Compared with the traditional technology, in this case, when the sealing piston works, it moves axially in the feeding tube, which can effectively scrape away the coffee powder accumulated in the feeding tube, solving the problem of easy clogging of the traditional feeding mechanism and ensuring the smooth feeding of coffee powder. At the same time, the precise coordination of the sealing piston and the power mechanism makes the feeding process highly controllable, and the feeding amount and time of coffee powder can be accurately adjusted according to needs, reducing waste.

[0037] In summary, the working principle of the present invention is reasonable and efficient. Through the innovative design of key components, the blockage problem in the feeding 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.

[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
