Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of food processing machinery, specifically a kind of food material processing machine. BACKGROUND

[0002] Food material processing machine is a common kitchen appliance, widely used in family and commercial occasions, for cutting processing various food materials.The existing food material processing machine usually includes a cutting chamber provided with cutting blade, food material enters cutting chamber through feed port, is cut or stirred by rotating blade, and is discharged through discharge port.Although such equipment can effectively process food material, the prior art still has some deficiencies, which affect the use effect and service life of the equipment.

[0003] 1. Blade deformation problem: in the prior art, the blade of the food processing machine is usually directly installed on the knife holder driven by the power mechanism. When the motor runs at high speed, the cutting force and pressure generated by the rotation of the blade will form a large downward pressure during food processing. Due to the action of this downward pressure, the front end of the blade will have a tendency to rise upward, especially when cutting relatively hard food materials. This deformation will lead to reduced cutting efficiency and may cause uneven cutting, affecting the final cooking effect. At the same time, the long-term deformation of the blade will also cause fatigue damage of the blade, shorten the service life of the blade, increase the maintenance cost of the equipment and the inconvenience of the user.

[0004] 2. Knife holder and motor main shaft positioning instability problem: the knife holder of the existing food material processing machine is usually directly installed on the main shaft of the motor, and the motor drives the knife holder and blade to rotate for cutting through the main shaft. However, since the main shaft of the motor does not have additional positioning or support structure during high-speed operation, the lack of positioning of the main shaft leads to small deviation and deformation during cutting. This deformation of the main shaft not only affects the stable rotation of the blade, but also may cause the contact angle between the blade and the food material to change, further exacerbating the problem of blade warping and uneven cutting. Long-term deformation of the main shaft will reduce the service life of the motor, and may cause the connection part of the motor and the knife holder to loosen, increasing the frequency of repair and replacement.

[0005] In summary, the blade of the existing food material processing machine is prone to deformation due to downward pressure during cutting, which leads to poor cutting effect and shortens the service life of the blade. In addition, the design of directly installing the knife holder on the top of the motor makes the main shaft lack effective positioning support, which easily leads to deformation of the main shaft, thereby affecting the cutting precision and stability of the blade. These problems adversely affect the performance of the equipment in actual use, so it is necessary to make further improvements. SUMMARY

[0029] The utility model discloses a food material processing machine, which comprises a main body 1, a cutting chamber 2 arranged at the top of the main body 1, a feeding port connected to a feeding hopper 3 arranged at the top of the cutting chamber 2, a discharge port connected to a discharge nozzle 4 arranged at the bottom of the cutting chamber 2, a cutting knife 5 arranged in the cutting chamber 2, a cutting edge 53 of the cutting knife 5 covering the feeding hopper 3 in a rotating track, the cutting knife 5 being driven to rotate by a power mechanism, and food materials entering the cutting chamber 2 from the feeding hopper 3 being cut and then falling out of the discharge nozzle 4; the cutting knife 5 comprises a knife holder 51 and a blade 52 arranged on the upper surface of the knife holder 51, the blade 52 being provided with the cutting edge 53 in a rotating direction, and a reinforcing rib plate 54 arranged on the side opposite to the cutting edge 53 and extending downward to the back surface of the knife holder 51.

[0030] In one embodiment, the lower end surface of the knife holder 51 is provided with a pushing surface 55, which is arranged in an inclined manner with a small thickness in the direction of the cutting edge 53 and a large thickness in the direction of the back of the blade.

[0031] In one embodiment, the blade 52 is provided with a plurality of mounting counterbores 56, the knife holder 51 is provided with mounting screw holes 57 corresponding to the positions of the counterbores 56, and fixing screws 58 are arranged to pass through the counterbores 56 and the screw holes 57 to connect the blade 52 to the upper surface of the knife holder 51.

[0032] In one embodiment, the reinforcing rib plate 54 is formed by bending the body material of the blade 52 downward.

[0033] In one embodiment, the cutting edge 53 is arranged in two symmetrical parts with respect to the rotating center of the blade 52 and arranged on the blade 52 in a diagonal manner.

[0034] In one embodiment, the power mechanism is a driving motor 6 arranged in the main machine, a main shaft 61 of the driving motor 6 extends into the cutting chamber 2 and is connected to the cutting knife 5, and the main shaft 61 further extends out of the top of the cutting chamber 2 and is connected to a center positioning mechanism arranged outside the cutting chamber 2.

[0035] In one embodiment, the center positioning mechanism comprises a center hole arranged at the top of the cutting chamber 2, a center sleeve 62 arranged above the center hole, and the main shaft 61 rotatably arranged in the center sleeve 62.

[0036] In one of the embodiments: the center sleeve 62 is installed with an anti-wear copper sleeve 63, and the main shaft 61 is coaxially matched with the anti-wear copper sleeve 63.

[0037] In one of the embodiments: the center sleeve 62 is installed with a bearing, and the main shaft 61 is coaxially matched with the bearing.

[0038] In one of the embodiments: the discharge port is installed with a separation screen 7.

[0039] In one of the embodiments: the top of the cutting chamber 2 is detachably covered with a top cover 21, the feeding hopper 3 is arranged on the top cover 21, the top of the cutting chamber 2 is provided with a positioning column 22, and correspondingly, the bottom of the top cover is provided with a positioning groove 23, when the top cover 21 is installed, the positioning column 22 is inserted into the positioning groove 23 to limit the installation position of the top cover, thereby facilitating the concentric matching of the center sleeve with the main shaft of the motor. In addition, the cooperation between the positioning groove and the positioning column can firmly lock the position of the top cover with the help of the spring buckle 24 arranged on the main machine, so as to avoid displacement of the top cover during use of the equipment. The arrangement of the spring buckle 24 facilitates the user to quickly disassemble the top cover, thereby facilitating the user to clean the cutting chamber.

[0040] Working principle: in the use process, the food material first enters the inside of the cutting chamber 2 through the feeding hopper 3. The cutting knife 5 is powered by the driving motor 6 installed in the main body, and the driving motor is connected with the cutting knife through its main shaft 61. The rotation of the main shaft drives the cutting knife 5 to rotate at high speed. In the process of rotation of the cutting knife, the cutting edge 53 of the blade 52 contacts with the food material and produces a cutting effect. The rotation track of the cutting edge covers the discharge port of the feeding hopper, so as to ensure that all the food materials entering the cutting chamber can be fully cut by the cutting knife.

[0041] Among them, the cutting knife 5 not only includes the cutting edge 53, but also is provided with a reinforcing rib plate 54. The reinforcing rib plate is formed by downward bending of the blade body material and is located on the opposite side of the cutting edge. When the cutting knife rotates to cut the food material, the blade is prone to upward warping deformation due to the existence of downward pressure, and the reinforcing rib plate provides additional support, so that the blade is more stable during cutting, effectively preventing the deformation of the blade caused by cutting pressure. This design ensures the stability and precision of the cutting tool during long-term use, and reduces the problem of uneven cutting caused by deformation of the blade.

[0042] Further, the lower end surface of the cutter holder 51 of the cutting knife in the case is provided with a pushing surface 55. The pushing surface is designed as an inclined surface with a thin front and a thick back. During the rotation of the cutter, the pushing surface generates a pushing force, which can guide the food material towards the cutting edge, making the contact between the food material and the cutting edge more sufficient, thereby improving the cutting efficiency. This design not only reduces the jamming of the food material, but also improves the continuity and uniformity of the cutting, especially when dealing with larger or harder food materials.

[0043] Further, the main shaft 61 of the driving motor is not only responsible for driving the cutting knife, but also ensures its stability through a center positioning mechanism. The positioning mechanism is composed of a center sleeve 62 at the top of the cutting chamber. The main shaft passes through the center hole and cooperates with the anti-wear copper sleeve 63 or bearing inside the center sleeve. The center sleeve provides additional support to prevent the main shaft from shifting or deforming during high-speed rotation. This design solves the problem of instability in the prior art due to the lack of support for the main shaft, ensuring smooth operation of the cutter, thereby improving the working reliability and cutting accuracy of the entire food processor.

[0044] The cut food material is discharged through the discharge nozzle at the bottom of the cutting chamber. A separation screen 7 is provided at the discharge port, which can effectively separate larger particles of food material, preventing incompletely cut food material from being discharged together with the cut finished product. The function of the separation screen is to ensure that the food material can be fully cut, improve the uniformity of the food and the smoothness of the discharge, and also avoid the phenomenon of discharge port blockage. After passing through the separation screen, the food material is dispersed, so that the final food material is in a fluffy and loose state, which makes it uniform and in contact with the air, which is beneficial to keeping the food material dry and prolonging its deterioration time.

[0045] Through these technical improvements, the cutting performance, stability and durability of the food material processor are greatly improved, solving the problems of blade deformation and unstable positioning of the main shaft in the prior art, so it can be widely used.

[0046] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
