Description
Technical Field
The utility model relates to a can dismantle locking mechanical system of blade especially relates to a domestic food processing machine is with locking mechanical system who can dismantle blade.
Background
Due to the characteristics of complete functions, small volume, easy operation, high quality and low price, the household food processor has been more and more introduced into the family life of people. The household food processor mainly comprises a meat chopper, a juice extractor, a stirrer, a soybean milk machine, a flour mill and the like. With the progress of technology and the development of the domestic food processing machine, the domestic food processing machine tends to be multifunctional, namely, the multifunctional functions of meat chopping, juicing, grinding, milling and the like are realized on the same processing machine by switching blades.
In order to switch the blades conveniently, various structural modes are designed. For example, the detachable tool represented by "food processor with different tools" disclosed in CN1543322A is a tool provided on a bowl, each tool corresponds to a bowl, and when the tool is replaced, the bowl must be replaced at the same time, so as to achieve the purpose of processing different foods by using different tools. Similar to the structure of the knife of food processor, as disclosed in CN201082135, there is a fan-shaped socket on the knife holder, and the driving shaft is also designed as a fan-shaped column matching with the socket, so that the bowl needs to be replaced when the knife is replaced.
In addition, like a popular multifunctional food processor in the market at present, the cutter and the bowls are arranged together, each bowl corresponds to one cutter, and the bottom of each bowl is provided with a cutter holder matched with the driving mechanism. This construction needs to be replaced together with the bowl when the tool is replaced. This not only wastes materials, but also brings trouble to the cleaning of the knife and bowl since the knife is fixed on the bowl. Due to the non-detachability of the traditional cutter, the volume of the cutter frame is limited, the cutter frame is required to have a larger circumference by the extension of the cutter, and the larger the cutter frame is, the more inconvenient the user uses; even more fatal is that the diameter of the bottom of the mixing tank using the conventional blade holder is also limited, which directly restricts the processing capacity of the food.
Disclosure of Invention
The utility model aims to solve the technical problem that the current situation to prior art provides a tool detachable, and can not produce the locking mechanical system that can dismantle the blade of domestic food preparation machine of flying knife phenomenon when initial rotation.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: this locking mechanical system of domestic food processor with dismantling blade includes:
the cutter is used for cutting and crushing the material to be processed;
the tool apron is connected with a driving mechanism of the food processor, a tool is detachably arranged on the tool apron, and the tool is driven by the driving mechanism to rotate together;
the method is characterized in that:
the cutter is fixed on the outer wall of the cutter frame, a longitudinal through hole capable of containing the cutter holder is formed in the middle of the cutter frame, and at least one bump is arranged on the inner wall of the through hole;
the transmission shaft is driven by a driving mechanism of the food processor to rotate, and the tool apron is fixed on the transmission shaft;
the outer wall of the tool apron is provided with a groove for the lug to penetrate into and be accommodated in, and two opposite side walls of the groove are respectively provided with corresponding concave parts for the lug to be clamped in.
Different blades are fixed on different knife rests, the blades can be replaced by replacing the knife rests, compared with the method that the blades are fixed on bowls, the material consumption is saved, and the blades are completely exposed and easy to clean; and the matching relation of the convex block in the tool rest and the concave part in the groove on the tool apron ensures that when the driving mechanism drives the transmission shaft to suddenly and rapidly rotate, the convex block can enter the concave part to be firmly clamped under the action of instant static inertia, thereby effectively avoiding the occurrence of flying to the tool rest and ensuring safer use.
Preferably, there are two bumps, and correspondingly, there are two grooves; due to the design of the symmetrical structure, the knife rest and the knife holder are stressed more uniformly, and the service life is effectively prolonged.
The concave part can be arc-shaped, and the arc-shaped design is convenient for the convex block to be smoothly clamped in or separated from the convex block.
At present, oil-containing bearings are mostly adopted by a household food processor as inserts of a transmission shaft, when a tool of the household food processor rotates and cuts, the rotating speed of the tool generally reaches over 12000 r/min, under high rotating speed, the relative friction between a shaft and the bearings is very frequent, and the high-speed friction between the shaft and the oil-containing bearings can cause poor matching between the shaft and the bearings and uneven cutting stress of the tool, so that the service life of the tool is shortened, and the food processing efficiency is reduced. Even if the joint gap between the shaft and the bearing is enlarged, water leakage may occur. The rolling bearing can effectively improve the stability of the rotation of the cutter at high rotation speed, avoid the phenomena of water leakage, shaft surface abrasion and the like, and greatly prolong the service life of the machine.
When the power supply is just started to be switched on, the tool apron suddenly rotates, so that a slipping phenomenon is generated between the tool apron and the through hole, the possibility of flying out of a tool is increased, and in order to increase the friction force between the tool apron and the tool rest and prevent the tool rest from slipping, as an improvement of the scheme, the tool apron can be provided with a boss-shaped joint part which is positioned below the groove and can be accommodated in the through hole, the joint part is provided with an annular groove along the outer wall of the joint part, and an anti-slip rubber ring for increasing the friction force between the through hole and the joint part is arranged in the annular groove.
Compared with the prior art, the utility model realizes the disassembly of the cutter through the detachable matching of the cutter frame and the cutter holder, and compared with the method that the cutter is fixed on a bowl and the cutter is replaced by disassembling the bowl, the utility model not only saves raw materials, but also makes the cleaning of the cutter more convenient and easier; the matching design of the groove and the bump, particularly the design of the concave part in the groove, ensures that the cutter can be automatically locked in the concave part under the action of inertia at the initial rotation, effectively prevents the occurrence of cutter flying and ensures the use safety; the anti-slip rubber ring on the boss can effectively prevent the tool apron and the tool rest from slipping in the rotating process; and the rolling bearing is adopted to transmit rotation, so that the stability and the safety of transmission under the condition of high-speed rotation are improved.
The self-locking performance of the self-locking cutter solves the problems of stability and noise at higher rotating speed. The traditional tool rest has the rotating friction and vertical jumping between a shaft and a bearing. At high speeds above 20000 rpm, mechanical noise is more pronounced. Tool holder life also decreases with higher rotational speeds. Since friction always causes the tool holder to develop in the direction of damage.
Anti-flying characteristic of self-locking cutter
In the development process of the self-locking knife, the phenomenon that the self-locking knife flies out at the rotating speed of 16000 r/min or more is encountered. After analyzing the essence of the problem, the company adds an anti-skid rubber ring on the tool apron. The rubber ring enables the cutter to be stronger in stability in a high-speed state, and the anti-vibration performance of the cutter is stronger. The existence of the rubber ring enables the locking piece and the cutter holder to have a pretightening force. When viewed from the tool apron, the pretightening force direction is downward, and the pretightening force direction has a tendency of preventing the tool apron from separating outwards. With the pretightening force, the tool apron is matched with the locking piece to obtain the pretightening force. The tendency that the cutter holder slides out of the concave pit due to slight vibration is eliminated, and the phenomenon of cutter flying completely disappears. The rubber ring is embedded in the retaining member with the ring surface being higher than the retaining member surface. The contact between the inner cavity of the holder and the outer surface of the locking member is actually the contact between the surface of the rubber ring and the inner cavity of the holder. The contact is compacted due to the extrusion of the rubber ring, and a pretightening force for preventing the cutter holder from sliding outwards is generated.
The utility model discloses be particularly suitable for the minigranulating of fruit and vegetable to smash, harder fruit is smashed and is milled, if the crushing of dry soybean, rice mill, the crushing of coffee bean mills, the ice shaving of ice-cube etc..
