Description

A meat grinder that prevents knife disc from being scratched Technical Field

[0001] The utility model relates to the technical field of small kitchen appliances, in particular to a meat grinder which is resistant to scratches on a knife disc. Background Art

[0002] An electric meat grinder is a machine that uses a motor to drive the meat through a spiral drive to push the meat into a knife disc with sieve holes, and uses the rotation of the blade to cut the meat into small pieces.

[0003] For example, the Chinese utility model with authorization announcement number CN 204841865 U discloses an electric meat grinder, in which a meat grinder rod is inserted into a meat grinder drum from left to right, a mounting shaft is provided at the left end of the meat grinder rod, the front end of the mounting shaft is cylindrical, and the rear end is prismatic, a blade is inserted and fixed at the rear end of the mounting shaft of the meat grinder rod, and rotates with the meat grinder rod: a cutter disc is inserted at the front end of the mounting shaft of the meat grinder rod, at least one notch is provided on the outer circumferential surface of the cutter disc, a limit block corresponding to the notch on the cutter disc is provided on the inner wall of the left end of the meat grinder drum, a knife cover is screwed onto the left end of the meat grinder drum, thereby axially positioning the minced meat, and the cutter disc is fixed to the meat grinder drum, and the fixing method of the cutter disc is very simple. The blades of such a meat grinder are set close to the cutter disc, which is conducive to the cutting and squeezing of ingredients. However, after working for a period of time, the blades will gradually come into contact with the cutter disc and produce friction. The greater the friction between the cutter disc and the blades, the easier it is for the cutter disc to wear. The metal worn by the cutter disc enters the ground food, which will seriously affect food hygiene. The most obvious thing is that the ground meat has black particles.

[0004] Therefore, the existing technology for the above problems still needs to be improved. Technical Solutions

[0005] The purpose of the utility model is to provide a meat grinder that can prevent the blade from being scratched, in view of the defects and shortcomings of the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model provides a meat grinder that can prevent a cutter disc from being scratched, comprising a meat grinder, a conveying screw, a blade and a cutter disc, wherein a processing chamber is formed in the meat grinder, a feeding channel leading to the processing chamber is provided on the meat grinder, a discharge port is opened at the head end of the meat grinder, the discharge port is communicated with the processing chamber, the cutter disc cover is arranged on the discharge port, a positioning hole and a discharge hole are provided on the cutter disc, the conveying screw and the blade are both arranged in the processing chamber, the head end of the conveying screw can be rotatably arranged in the positioning hole, the tail end of the conveying screw is transmission-connected with a driving mechanism, the blade is arranged at the head end of the conveying screw, the blade is close to the cutter disc, and a pressure fine-tuning mechanism is also included, the pressure fine-tuning mechanism is used to adjust the pressure between the cutter disc and the blade, and the pressure fine-tuning mechanism is arranged at the head end or the tail end of the conveying screw. Through the above-mentioned structural arrangement, when the present invention is mincing meat, the knife disc and the blade undergo relative movement in the circumferential direction and squeeze each other at the same time. The pressure fine-tuning mechanism can effectively prevent excessive pressure from being generated between the knife disc and the blade, and can appropriately control the friction between the knife disc and the blade, thereby preventing the knife disc from being scratched by the blade.

[0008] According to the above solution, the pressure fine-tuning mechanism includes an elastic component, which can be a silicone member or a spring. With this structural arrangement, when the cutter disc is placed over the meat grinder outlet, the cutter disc applies pressure to the blades and conveying screw. The elastic component can partially release this pressure, eliminating excessive pressure between the cutter disc and the blades, ensuring the blades can function normally and preventing them from being easily scratched.

[0009] According to the above solution, the drive mechanism includes a connector, and the tail end of the conveying screw is formed with an insert block, which is inserted into the connector. When the elastic component is installed at the tail end of the conveying screw, one end of the elastic component abuts against the connector, and the other end of the elastic component abuts against the conveying screw. Through the above structural arrangement, when the cutter head cover is installed at the outlet of the meat grinder, the cutter head applies pressure to the blade and the conveying screw, causing the elastic component between the connector and the conveying screw to contract, which can release some of the pressure, so that there is not too much pressure between the cutter head and the blade, ensuring that the blade can work normally and will not easily scratch the cutter head.

[0010] According to the above solution, the present invention also includes a wear-resistant member, which is mounted on the outer peripheral wall of the connector. One end of the wear-resistant member contacts the silicone member, and the other end contacts the working chamber wall of the meat grinder. The wear-resistant member is generally made of POM plastic. This structural arrangement prevents the conveying screw from rubbing against the inner wall of the meat grinder when it rotates and is compressed, thereby preventing the generation of black particles.

[0011] According to the above solution, a mounting shaft is formed at the head end of the conveying screw, and the blade is mounted on the mounting shaft. When the elastic component is installed at the head end of the conveying screw, one end of the elastic component abuts against the blade, and the other end of the elastic component abuts against the conveying screw. With this structural arrangement, when the cutter disc cover is installed at the outlet of the meat grinder, the cutter disc applies pressure to the blade and the silicone component, causing the silicone component to contract and release some of the pressure, thereby reducing excessive pressure between the cutter disc and the blade, ensuring that the blade can function normally and will not easily scratch the cutter disc.

[0012] According to the above solution, the mounting shaft is formed with a first special-shaped structure, the blade is sleeved on the outer peripheral wall of the first special-shaped structure, and the end of the mounting shaft away from the conveying screw is inserted into the positioning hole. This structural arrangement can achieve power transmission, and when the conveying screw rotates, it can drive the blade to rotate synchronously.

[0013] According to the above solution, the installation shaft is formed with a second special-shaped structure, and the elastic component is sleeved on the outer peripheral wall of the second special-shaped structure. Through the above structural arrangement, the position of the elastic component can be limited, which is convenient for installation.

[0014] According to the above solution, the utility model also includes a blade cover, which has a central hole for convenient material discharge. The blade cover is screwed onto the head end of the meat grinder drum. One side of the blade disc is close to the blade, and the other side of the blade disc is against the inner side of the blade cover. This structural arrangement facilitates the installation of the blade disc.

[0015] According to the above solution, the outer edge of the cutter disc is provided with a positioning notch / block, the outlet at the head end of the meat grinder is provided with a positioning block / notch, the cutter disc is mounted on the outlet, and the positioning notch matches the positioning block. This structural arrangement effectively prevents the cutter disc from rotating during operation. Beneficial effects

[0016] Beneficial effects of the utility model:

[0017] When the utility model minces meat, the knife disc and the blade move relative to each other in a circular direction and squeeze each other at the same time. The pressure fine-tuning mechanism can effectively prevent excessive pressure from being generated between the knife disc and the blade, and can appropriately control the friction between the knife disc and the blade, thereby preventing the knife disc from being scratched by the blade.

The head end of the conveying screw 2 is rotatably arranged in the positioning hole 41. The tail end of the conveying screw 2 is connected to the driving mechanism. The blade 3 is arranged at the head end of the conveying screw 2. The blade 3 and the conveying screw 2 are coaxial and rotate synchronously. The pressure fine-tuning mechanism is used to adjust the pressure between the cutter disc 4 and the blade 3. The pressure fine-tuning mechanism is arranged at the head end or the tail end of the conveying screw 2. Through the above-mentioned structural arrangement, when the present invention is mincing meat, the cutter disc 4 and the blade 3 undergo relative motion in the circumferential direction and squeeze each other at the same time. The pressure fine-tuning mechanism can effectively prevent excessive pressure from being generated between the cutter disc 4 and the blade 3, and can appropriately control the friction between the cutter disc 4 and the blade 3, thereby preventing the cutter disc 4 from being scratched by the blade 3.

[0025] Furthermore, the pressure fine-tuning mechanism includes an elastic component 6, which can be a silicone component or a spring. In this embodiment, the elastic component 6 is preferably a silicone component, which is arranged at the tail end of the conveying screw 2. The driving mechanism includes a connector 7, which is connected to the drive motor through a tooth structure.
