Description

A grinding machine with an integrated double-disk structure and its assembly method

technical field

The invention relates to the technical field of food cutting and grinding machines, in particular to a grinding machine with an integrated double-disk structure and an assembly method thereof.

Background technique

In the conditioning of fruits, vegetables and beans, there are various conditioning machines for grinding and squeezing food and fruits and vegetables, so that people can quickly obtain nutritional supplements. Rotate to cut and break the vegetables, fruits and beans. If the crushed fruits, vegetables and beans need to be further refined, it needs to be equipped with a grinding structure to achieve it. At present, various grinders on the market have different settings for the grinding structure. Can be divided into detachable and non-detachable two categories:

The non-detachable type is to fix the knife set and the grinding structure at the bottom of the container. The advantage of this type of grinder is that it is convenient for production and processing, but this advantage also brings a great disadvantage, that is, it is not easy to clean , after the user squeezes the juice or grinds, the knife set and the grinding structure cannot be taken out for cleaning, resulting in the inability to clean up the food residues hidden in the corners, which will affect the next food processing, and will bring a greater health hazard. Due to the poor experience of users, similar grinders have basically withdrawn from the market;

The other type came out at the historic moment in order to solve the shortcomings of the aforementioned grinding machines. This type of grinding machine adopts the mode of separate setting of the grinding structure and the knife group. First, the upper grinding disc in the grinding structure is fixedly connected with the container by ultrasonic welding. Further, the lower grinding disc in the grinding structure and the knife set are fixed together and connected to the container through the clamping structure, so that the knife set, the grinding structure and the container can be disassembled. Although this method solves the problem of inconvenient disassembly and washing, However, there are still many disadvantages. For example, since the container is made of plastic and the upper grinding disc is made of metal, the connection of the two by ultrasonic welding will cause the upper grinding disc to fall off during use due to the difference in thermal expansion coefficient, which will cause certain problems. Safety accidents will also affect the mutual movement of the upper and lower grinding discs; more prominently, this split arrangement will bring great difficulties to the assembly of parts. Once the accuracy is not properly grasped, there will be up and down The grinding discs interfere with each other. In the process of mass manufacturing and assembly, the gap between the upper and lower grinding discs is quite uncertain, and the scrap rate of the product is extremely high, which further increases the difficulty of product quality control and will lead to cost. It has been high, and once the processing parameters of equipment equipped with a certain type of grinding machine are adjusted, only this type of grinding machine can be processed, and other types of grinding machines cannot be used, resulting in empty equipment resources and making manufacturing costs again. The increase not only makes the price of the final product high, but also unsatisfactory in terms of user experience.

The drive base is connected, specifically, the lower end of the drive shaft 6 does not exceed the lower end face of the container 1, the upper grinding disc 302 is fixed on the sealing base 4, and the inner wall of the juice outlet 2 is formed with a first positioning step 7 for positioning the upper grinding disc 302. A first elastic seal 8 is provided between the grinding disc 302 and the first positioning step 7; when the user needs to extract juice or grind, the grinder is placed on the driving base, and then the driving shaft 6 is driven to rotate, thereby driving the cutting tool 301 Rotate and cut fruits and vegetables, and cut it into small pieces, while the lower millstone 303 rotates relative to the upper millstone 302 to grind small pieces of food; by fixing the upper millstone 302 and the lower millstone 303 on the sealing base 4 , and assembled on the basis of the axis of the drive shaft 6, thereby avoiding the problem that the gap between the upper and lower grinding discs 303 is difficult to ensure accuracy due to the processing technology of the container 1 and the sealing base 4, and the assembly is convenient and quick, thereby ensuring the grinding machine It is convenient to disassemble and clean while reducing manufacturing and processing costs.

Preferably, the upper grinding disc 302 is provided with a perforation 9 for the drive shaft 6 to pass through, and the upper grinding disc 302 is connected to the sealing base 4 through the fixing column 10. Specifically, there are three fixing columns 10 and they are all located on the edge of the upper grinding disc 302. Flat, in order to avoid the fixed column 10, the lower grinding plate 303 is located in the area surrounded by the three fixed columns 10, in addition, the fixed column 10 and the upper grinding plate 302 can be set in one piece or separately, and different processing can be selected according to different applications Mode; the upper grinding disc 302 is annular and its inner hole forms a perforation 9 to facilitate the assembly of the drive shaft 6 and allow food fragments to enter the grinding track.

Further, the adjustment of the distance between the upper grinding disc 302 and the lower grinding disc 303 can be realized by simply adjusting the height of the fixed column 10 or the upper and lower positions of the drive shaft 6, the processing is simple and fast, and the precision requirements for the processing and assembly equipment Not high, different types of grinding machines can be interchanged for assembly equipment, no need to consider the problem of equipment resource occupancy, even manual assembly by workers can complete the assembly of qualified products in special periods, the requirements for product assembly are greatly reduced, and it is more conducive to the product cost control.

In addition, the traditional grinding machine with the upper grinding disc separately installed on the container, because the tool needs to pass through the upper grinding disc when the user disassembles and cleans it during use, the horizontal length of the tool cannot exceed the inner diameter of the upper grinding disc, otherwise it cannot be assembled, and thus cannot Realize the free adjustment of cutting tool, and look at this scheme on the contrary, the present invention sets upper grinding disc 302, lower grinding disc 303 and cutting tool 301 integrally, when disassembling and cleaning, the three are disassembled together, and this setting method can reduce the transverse length of cutting tool 301 The design is longer and is not limited by the inner diameter of the upper grinding disc 302.
