Mill of coffee-making machine

Abstract

The invention relates to a coffee machine grinder which comprises a grinding head, a cutter head, a cutter cover and a transmission mechanism. The grinding head is installed and fixed at the upper end of a vertical rotating shaft in the grinder, and the underside is provided with the cutter head. The cutter head and the cutter cover arranged in the grinder are in clearance fit. A coffee turnplate is also fixed in the vertical rotating shaft. The lower end of the vertical rotating shaft is connected with the transmission mechanism in a driving way. The coffee machine grinder is characterized in that the cutter head and the cutter cover are made from ceramic material; furthermore, the cutter head is spliced and connected with the coffee turnplate by a positioning pin; an elastic element is supported between the opposite surfaces of the cutter head and the coffee turnplate. The coffee machine grinder is provided with the cutter head and the cutter cover made from ceramic material and is combined with an elastic mechanism to ensure that a cutter head component is hard wearing, resists high temperature and corrosion and has less thermal deformation, high hardness and large strength, so as to ensure that the grinder grinds meals uniformly, outputs meals fast, reduces noise, has reasonable structure and is practical.

Description

technical field [0001] The present invention relates to a coffee machine grinder. Background technique [0002] With the continuous improvement of people's living standards, coffee machines have gradually entered the families of the majority of the people. Grinders are used in the coffee machines to facilitate grinding coffee beans into powder before making coffee. [0003] European Patent No. EP0684003B1 discloses a coffee grinder, especially suitable for coffee machines, which includes a conical grinding tool that can rotate around a vertical axis in the grinding collar, and is driven by a gear Transmission connection, the conical grinding tool is axially connected to a clutch disc, the clutch disc is connected to a rotatable transmission, in addition, a claw connector is provided between the clutch disc and the transmission, and the clutch disc A safety clutch is provided between the abrasive tool and the rotatable torque to limit the rotatable torque. The safety clutch ...

AI Technical Summary

Problems solved by technology

[0004] 1. The grinder adopts metal cutter head and knife cover, which is difficult to process, not wear-resistant, and easy to rust. The grinder has defects such as uneven grinding powder thickness, slow powder output, and loud noise.

[0005] 2. The structure of the unloading mechanism is complex and difficult to assemble; the most important thing is that the support plate under the slipping handle is easy to wear when overloaded, and a slight resistance will cause slipping, which will have a serious impact on normal use

[0006] 3. The elastic coupling device is difficult to assemble and has no obvious effect

[0007] 4. The original steel balls on the grinder are densely packed, which is prone to unevenness and unevenness, and the positioning stability is not good, and the assembly is labor-intensive and time-consuming

[0008] 5. The cutter head and the cutter holder of the original grinder are directly screwed on the plastic steel ball seat with self-tapping screws, which is easy to cause the screw to slip, which makes it difficult to fix the cutter head and the grinding effect is not good
