[0034] See also Figure 1-5 ,

[0035] A meat mincing mechanism that is easy to replace, comprising a housing 1, a support frame 8, a gear mechanism, and a cutting and stirring mechanism, wherein the support frame 8 is provided at the bottom of the housing 1, and the cutting and stirring mechanism is located inside the housing;

[0036] The cutting and stirring mechanism comprises: a meat-mincing roller 2 5 and a meat-mincing roller 1 3 installed inside the housing 1, and a cutter group fixedly connected to the meat-mincing roller 2 5 and the meat-mincing roller 1 3;

[0037] The reamer assembly comprises a plurality of blades 6 spirally distributed on the outer surface of the meat mincing roller, a blade mounting card 7 and a countersunk screw 10, wherein the countersunk screw is mounted at the countersunk threaded hole of the blade mounting card;

[0038] The gear mechanism is installed on the left side of the housing, and the gear mechanism includes a driving gear 2 and a driven gear 4;

[0039] Among them, the driving gear 2 and the driven gear 4 cooperate with each other to form a gear pair, and the meat grinding roller 2 5 and the meat grinding roller 1 3 rotate at a relatively uniform speed, which provides sufficient conditions for the uniformity of the mechanism's operation.

[0040] In this example, a special-shaped groove that cooperates with the blade 6 is opened at the mounting end of the blade mounting card 7, a cylindrical pin that interference fits with the meat grinder roller 25 is provided at the bottom of the blade mounting card 7, and an arc groove that matches it is opened at the contact part between the blade mounting card 7 and the cylindrical surface of the meat grinder roller 25.

[0041] Among them, the size of the arc groove of the blade mounting card 7 is adapted to the size of the meat grinder roller 2 and the size of the meat grinder roller 1, and the special-shaped groove matching the blade 6 is adapted to the shape of the blade 6, and does not exceed the upper and lower surfaces of the conical mounting surface of the countersunk screw 10. The use of the countersunk screw is beneficial to reducing the external dimensions of the detailed structure and improving the processability and aesthetics of the overall structure.

[0042] In this example, a through hole is opened on the meat mincing roller 2 5 to cooperate with the blade mounting card 7, and the spirals are evenly distributed on the meat mincing roller 5 and the meat mincing roller 1 3.

[0043] It should be noted that, because the blade mounting card 7 is interference fit with the meat grinding roller 2 5 and the meat grinding roller 1 3, it is necessary to knock the blade mounting card 7 with a tool from the other end of the installation during disassembly, so as to remove it from the inside of the meat grinding roller 2 5 and the meat grinding roller 1 3.

[0044] In this example, four bearing holes are respectively opened on the left and right sides of the shell 1, and four deep groove ball bearings 9 are installed in the four bearing holes in sequence. The left and right ends of the meat grinder roller 2 5 and the meat grinder roller 1 3 are installed in the inner rings of the deep groove ball bearings 9 located at the two ends of the shell 1, and the driving gear 2 and the driven gear 4 are respectively installed on the left ends of the meat grinder roller 2 5 and the meat grinder roller 1 3.

[0045] In this example, two countersunk threaded holes are opened diagonally at the top and bottom of the blade mounting card 7, and countersunk screws 10 are installed at both countersunk threaded holes.

[0046] It should be noted that opening countersunk threaded holes in diagonal non-coplanar areas can prevent stress concentration in parts and prevent the loosening of screws due to vibration in the mechanism.

[0047] In this example, the driving gear 2 and the driven gear 4 have the same number of teeth, and the housing 1 is provided with a feed inlet and a discharge outlet.

[0048] In this example, the blade 6 is flat and T-shaped, and has matching holes on the left and right sides of its bottom for matching with the countersunk screws 10 .

[0049] It should be noted that the detachable and lightweight design of the "T"-shaped blade 6 provides favorable conditions for the normal operation of the mechanism and the service life of the parts. There is no thread in the matching hole, and the preload force and constraint of the countersunk screw 10 are used to ensure that the blade 6 does not move left and right during movement.

[0050] In this example, a support frame 8 is welded to the bottom of the shell 1 , a feed port is opened at the top of the shell 1 , and a discharge port is opened at the right end inside the shell 1 .

[0051] To sum up, in this meat grinder mechanism which is easy to replace, the user feeds the material into the mechanism from the feed port on the top of the mechanism, and when the mechanism moves, the driving gear drives the driven gear, and the meat grinder roller 1 and the meat grinder roller 2 rotate relative to each other, and the blade mounted on the blade mounting card rotates at a constant speed. Because the blade is in a "T"-shaped spiral shape, the material is crushed and moved along the axial direction and sent out from the discharge port of the shell.

[0052] After the mechanism is used, the user uses a tool to unscrew the countersunk screws on the blade installation card. After all the screws are unscrewed, the blade can be pulled out from the special-shaped groove of the blade installation card by hand to perform centralized maintenance and cleaning of the blade. The installation of the blade is similar.

[0053] Beneficial effects:

[0054] 1. This meat grinder is easy to replace. Through the detachable design between the blade and the spiral shaft, the user can replace the blade without disassembling the main shaft and perform daily maintenance on the entire mechanism, thus achieving the purpose of convenient disassembly of the working part.

[0055] 2. The meat grinder mechanism which is easy to replace can replace various types and models of knives according to the needs of daily use through the separate blade clamping device, thereby achieving the purpose of strong interchangeability of the knife parts.

[0056] 3. This meat grinder which is easy to replace ensures the assembly processability of the shaft and the additional parts on the shaft through the shape of the main shaft stepped shaft, and realizes the purpose of convenient disassembly of the overall mechanism.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
