Utility Model Content

[0005] In order to prevent the feed port from being blocked, the present application provides a meat cutting and mincing device for meat processing.

[0006] The present application provides a meat cutting and mincing device for meat processing, which adopts the following technical solution:

[0007] A meat cutting and mincing device for meat processing comprises a processing box, a feed hopper mounted on the processing box, and a guide rod mounted in the feed hopper, a feed barrel mounted on the feed hopper, a feed hole for placing meat in the feed barrel, a mounting column is arranged in the end of the feed barrel close to the guide rod, a plurality of blades are fixedly connected to the outer peripheral surface of the mounting column, the ends of the blades away from the mounting column are fixedly connected to the inner wall of the feed barrel, a pressure plate is slidably arranged on the inner wall of the feed barrel, and a driving component for driving the pressure plate to move is arranged in the feed barrel.

[0008] By adopting the above technical solution, the operator puts the meat into the feed barrel from the feed hole, and then uses the driving assembly to drive the pressure plate to move. The movement of the pressure plate drives the meat to press against the blade, and the meat is cut into multiple pieces by the blade under the pressure of the pressure plate, which makes it convenient for the meat to enter the processing box through the feed hopper for further crushing, thereby preventing the feed hopper from being blocked due to excessive meat size, thereby improving the meat mincing efficiency.

[0009] Preferably, the driving assembly includes a driving screw passing through the pressure plate, a driving gear fixedly sleeved on the driving screw, and a transmission gear rotatably installed in the feed barrel, the driving screw passing through the feed barrel, the driving gear being arranged on the end of the driving screw passing through the inner wall of the feed barrel, a reciprocating motor being installed on the feed barrel, the transmission gear fixedly sleeved on the output end of the reciprocating motor, and the driving gear being meshed with the transmission gear.

[0010] By adopting the above technical solution, the operator starts the reciprocating motor, the reciprocating motor drives the transmission gear to rotate, the transmission gear rotation drives the driving gear to rotate, the driving gear rotation drives the driving screw to rotate, the driving screw rotation drives the pressing plate to move, and the pressing plate moves back and forth under the action of the reciprocating motor, which is convenient for the operator to cyclically throw in the meat for cutting.

[0011] Preferably, a baffle is fixedly connected to the top surface of the pressing plate, and the baffle is slidably disposed on the inner wall of the feed hole.

[0012] By adopting the above technical solution, when the pressing plate moves downward, the pressing plate drives the baffle to move, and the baffle blocks the feed hole, thereby preventing debris from entering the top surface of the pressing plate, hindering the resetting of the pressing plate, and thus damaging the equipment.

[0013] Preferably, a support plate is fixedly connected to the guide rod, a rotating rod is installed on the end of the mounting column close to the support plate, a plurality of cutting knives are fixedly connected to the rotating rod, and a control component for driving the rotating rod to rotate is provided on the mounting column.

The support plate pushes the cut meat to the position of the rotating rod. Then the operator uses the control component to drive the rotating rod to rotate, and the rotation of the rotating rod drives the cutting knife to rotate. The cutting knife cuts the lifted meat again, so that the meat can fall into the processing box more easily, thereby improving the efficiency of mincing meat in the processing box.

[0017] Preferably, the support plate is provided with a plurality of through holes for the crushed meat to pass through.

[0018] By adopting the above technical solution, the provision of the through holes makes it easier for the secondary crushed meat to enter the processing box, thereby preventing the feed hopper from being blocked.

[0020] By adopting the above technical solution, the operator inserts the mounting ring plate into the mounting ring groove, and then the operator uses the fixing assembly to fix the mounting ring plate, thereby facilitating the operator to install the feed barrel. The setting of the mounting ring plate prevents the feed barrel from horizontal deviation, thereby improving the stability of the equipment.

[0021] Preferably, the fixing assembly includes a positioning rod slidably inserted into the feed hopper, a positioning disc fixedly sleeved on the positioning rod, and a positioning spring fixedly connected to the positioning disc.

[0022] By adopting the above technical solution, the operator pulls the positioning rod, and the movement of the positioning rod drives the positioning disc to move. The movement of the positioning disc causes the positioning spring to be in a compressed state. Then the operator inserts the mounting ring plate into the mounting ring groove, and the positioning rod slides on the outer circumferential surface of the mounting ring plate. When the positioning rod moves to the position of the positioning slot, the positioning rod is inserted into the positioning slot under the action of the positioning spring, thereby fixing the feed barrel and facilitating the operator to install the feed barrel.

[0025] Preferably, a slope is provided on the end of the positioning rod passing through the feed hopper.

[0026] By adopting the above technical solution, the operator inserts the mounting ring plate into the mounting ring groove, and the positioning rod completely enters the feed hopper under the action of the inclined surface. The operator continues to insert the mounting ring plate. When the positioning rod moves to the position of the positioning slot, the positioning rod is inserted into the positioning slot under the action of the positioning spring, which is convenient for the operator to fix the feed barrel.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The operator puts the meat into the feed barrel from the feed hole, and then uses the driving assembly to drive the pressing plate to move. The movement of the pressing plate drives the meat to press against the blade. The meat is cut into multiple pieces by the blade under the pressure of the pressing plate, which facilitates the meat to enter the processing box through the feed hopper for further crushing, thereby preventing the feed hopper from being blocked due to excessive meat size and improving the meat mincing efficiency;

[0029] 2. The cut meat falls onto the support plate, which moves up and down continuously under the action of the guide rod. The support plate pushes the cut meat to the position of the rotating rod. Then the operator uses the control component to drive the rotating rod to rotate. The rotation of the rotating rod drives the cutting knife to rotate. The cutting knife cuts the lifted meat again, making it easier for the meat to fall into the processing box, thereby improving the efficiency of the meat grinding in the processing box.

[0030] 3. The operator pulls the positioning rod, and the movement of the positioning rod drives the positioning disc to move. The movement of the positioning disc compresses the positioning spring.
