Description

Technical Field

[0001] This application relates to the technical field of coffee bean grinding, and specifically to a grinding degree adjustment structure. Background Art

[0002] The grinding degree of coffee powder refers to the particle size of coffee beans after mechanical grinding, which is one of the important factors affecting the taste of coffee. Different grinding degrees are suitable for different types of coffee. According to the particle size, the coffee grinding degree can be divided into three types: coarse grinding, medium grinding, and fine grinding.

[0003] For example, the patent with the publication number CN220275459U specifically discloses a coffee bean grinder. This device drives the grinding part to grind coffee beans through a motor, and the ground coffee powder falls out from the powder outlet channel.

[0004] However, due to the fixed setting method of the grinding part of the above device, the particle size of the ground coffee powder is consistent. This design makes the above device only capable of producing coffee powder with a specific grinding degree. When coffee powder with different grinding degrees is needed, different grinding equipment needs to be replaced.

[0005] Therefore, it is necessary to provide a grinding degree adjustment structure to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art part is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0035] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail this application.

[0036] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0037] Such as Figure 1 - Figure 2As shown in the figure, the present application provides a grinding degree adjustment structure, including a base 4, on which a driving mechanism 1 is provided. In the present application, the driving mechanism 1 is a traditional belt drive structure, and its specific structure and principle are prior art and will not be elaborated here. A rotating shaft (not marked in the figure) is fixedly installed at the output end of the driving mechanism 1. The rotating shaft penetrates the base 4, and a first gear (not marked in the figure) is fixedly installed at one end of the rotating shaft close to the base 4;

[0038] Meanwhile, a grinding mechanism 2 is installed on the base 4. The grinding mechanism 2 includes a first transmission shaft 23 rotatably installed on the base 4. A second gear (not marked in the figure) is fixedly installed at the end of the first transmission shaft 23. The second gear meshes with the first gear, so that the second gear can rotate driven by the first gear;

[0039] As Figure 3 - Figure 4 shown, an adjustment mechanism 3 is installed on the base 4. The adjustment mechanism 3 includes a fixed plate 35 fixedly installed on the base 4. A notch is provided on the fixed plate 35, and a movable plate 36 is slidably installed inside the notch;

[0040] Meanwhile, a second transmission shaft 24 is rotatably installed on the movable plate 36. A first pulley 25 is installed at one end of the second transmission shaft 24 away from the gear on the first transmission shaft 23. Meanwhile, a second pulley is fixedly installed at the other end of the rotating shaft close to the base 4, and a belt 26 is arranged for transmission between the second pulley and the first pulley 25, so that the first pulley 25 can rotate synchronously with the second pulley;

[0041] It should be noted that since both the second gear and the first pulley 25 are driven by the driving mechanism 1, the rotation directions of the second gear and the first pulley 25 are opposite;

[0042] As Figure 1 - Figure 2 shown, a second grinding roller 22 is fixedly installed on the first transmission shaft 23, and a first grinding roller 21 is fixedly installed on the second transmission shaft 24. The outer circles of the first grinding roller 21 and the second grinding roller 22 are close to each other and have a gap for grinding coffee beans, so that the first grinding roller 21 and the second grinding roller 22 are adapted to rotate towards each other to grind coffee beans;

[0043] As Figure 2 - Figure 3 shown, an adjustment part is rotatably installed on the base 4. The adjustment part is adapted to drive the movable plate 36 to move vertically in the notch of the fixed plate 35 to adjust the gap between the first grinding roller 21 and the second grinding roller 22. Specifically:

[0044] The adjustment part includes an adjustment shaft 33 rotatably arranged at the top of the base 4. A connection block 32 is installed at the top of the adjustment shaft 33, and an adjustment handle 31 is fixedly installed on the connection block 32 to facilitate rotating the adjustment shaft 33;

[0045] Meanwhile, the bottom of the adjusting shaft 33 passes through the base 4, and a screw rod 34 is fixedly installed thereon. An adjusting block 37 is fixedly installed on the movable plate 36. The screw rod 34 passes through the adjusting block 37 and is screwed with the adjusting block 37. Thus, by rotating the adjusting shaft 33 with the adjusting handle 31, the screw rod 34 can be driven to rotate. At this time, the cooperation between the screw rod 34 and the adjusting block 37 can drive the adjusting block 37 and the movable plate 36 to move in the vertical direction, and further drive the first grinding roller 21 on the second transmission shaft 24 to move in the vertical direction, so that the first grinding roller 21 approaches or moves away from the second grinding roller 22, and then the gap between the first grinding roller 21 and the second grinding roller 22 can be adjusted, and products with different grinding degrees can be obtained;

[0046] An adjusting scale 38 is provided on the fixed plate 35, and a scale arrow 39 is fixedly installed at the position of the movable plate 36 corresponding to the adjusting scale 38. The adjusting scale 38 corresponds to the grinding degree, so as to facilitate adjustment to a suitable grinding degree;

[0047] As Figure 4 shown, a pneumatic spring 310 is fixedly installed on the base 4. A pulley 311 is rotatably installed on one side of the pneumatic spring 310 close to the belt 26. In the initial state, the pulley 311 pushes one side of the belt 26 to contract inward under the action of the pneumatic spring 310, ensuring that the belt 26 is in a tensioned state;

[0048] When the second transmission shaft 24 moves upward, the second transmission shaft 24 drives the first pulley 25 to move upward. At this time, the first pulley 25 pulls the belt 26 to be tightened, then the belt 26 will push the pulley 311 toward the pneumatic spring 310, causing the pneumatic spring 310 to contract. When the second transmission shaft 24 moves downward, the first pulley 25 drives the belt 26 to relax. At this time, the pneumatic spring 310 resets and pushes the pulley 311 to tighten the belt 26, ensuring the transmission of the second transmission shaft 24.

[0049] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
