Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean grinders, in particular to an electric slide table for adjusting a knife disc of a coffee bean grinder. Background Art

[0002] In the coffee preparation process, the particle size of ground coffee beans has a decisive influence on the final flavor and quality of coffee. Different coffee making methods, such as espresso, drip or French press, require coffee powder of different coarseness and fineness. The grinder that can accurately control the particle size of coffee beans has become an indispensable equipment in coffee preparation.

[0003] However, traditional coffee grinders mostly use manual methods to adjust the spacing of the grinding blades, physically rotating the components to change the grinding particle size. This manual adjustment method is not only cumbersome to operate and requires high operator skills, but also difficult to achieve accurate and repeatable grinding settings. In addition, the manual adjustment mechanism is prone to wear and loss of precision after long-term use, affecting the grinding quality and reliability of the equipment. Utility Model Content

[0004] In response to the above problems, the utility model provides an electric slide for adjusting the blade disc of a coffee bean grinder, which effectively solves the problems of cumbersome operation of manually adjusting the spacing of the grinding blade discs, high skill requirements for the operator, and easy wear and loss of precision after long-term use.

[0005] The utility model adopts the following technical solutions:

[0006] The cam is provided with a first plate, and a second plate is provided on the top of the motor fixing plate, and a rotating shaft base is provided on the top of the motor fixing plate, and a second plate is provided on the top of the motor fixing plate, and a second plate is provided between the second plate and the inner wall of the first plate. The two sliding rods are slidably connected with sliding blocks, and the rotating end of the reduction motor passes through the rotating shaft base and is connected with a threaded rod, and the threaded rod passes through one side of the first concave plate and is threadedly connected with the sliding block in the first concave plate. The two sliding blocks are rotatably connected with the first concave plate and the second concave plate on both sides, and a servo motor is installed on the top of the second concave plate. The rotating end of the servo motor is connected with a lower knife disc fixing frame, and an upper knife disc fixing frame is provided above the lower knife disc fixing frame, and a grinding knife disc is installed in the upper knife disc fixing frame and the lower knife disc fixing frame.

[0007] Furthermore, the cross bracket includes two connecting rods, which are rotationally connected via a rotating shaft, wherein one end of one of the connecting rods is rotationally connected to one side of the slider in the second concave plate, the other end of one of the connecting rods is rotationally connected to one side of the first concave plate, one end of the other connecting rod is rotationally connected to one side of the slider in the first concave plate, and the other end of the other connecting rod is rotationally connected to one side of the second concave plate.

[0008] Furthermore, the grinding disc is made of a wear-resistant and corrosion-resistant material.

[0009] Furthermore, the slider and the cross bracket are connected by high-strength bolts.

[0010] The advantages of the utility model are that the distance between the cutter discs can be precisely adjusted by a reduction motor. This precision is particularly suitable for scenarios where fine adjustments are required based on different coffee beans and grinding requirements, thereby ensuring the consistency and repeatability of each grinding. The operator's physical labor and the manual adjustments required during the grinding process are reduced, making the operation more convenient and efficient. The user can focus more on other steps in the coffee making process. The stability of the entire mechanism is enhanced by using high-strength bolts to connect the slider and the cross bracket. The use of wear-resistant and corrosion-resistant materials extends the service life of the equipment and reduces maintenance costs. The use of a motor allows the cutter disc adjustment mechanism to respond quickly to the operator's adjustment instructions, and can adapt to different grinding requirements more quickly than manual adjustment, especially when frequent adjustments to the coarseness of the grinding are required.
