[0002] With the continuous progress of technology and the improvement of people's requirements for the quality of life, the meat processing industry is also gradually developing and growing, and the demand of meat processing enterprises for meat processing machinery is also increasing continuously. Among these meat processing machinery, the meat slicer is a very important device.

[0003] A meat slicer refers to a machine that cuts meat into specified sizes and shapes. The most commonly used meat slicer is a vertical meat slicer, which can directly cut and slice fat beef square bricks and round rolls at minus more than ten degrees Celsius. Most vertical meat slicers adopt a reciprocating feeding method, with low efficiency; and there is a large waste of material heads. Content of the Utility Model

[0004] The utility model provides a continuous feeding mechanism and a meat slicer thereof, which solve the problems that the current feeding mechanism cannot achieve continuous feeding, with low efficiency; and there is a large waste of material heads.

[0005] The utility model relates to a continuous feeding mechanism, which includes a feeding platform. A lower-layer conveying and feeding mechanism for supporting reciprocating rotation and unidirectional material conveying is installed on the feeding platform. An upper-layer pressing and conveying mechanism for pressing the top of the material and cooperating with the lower-layer conveying and feeding mechanism for reciprocating rotation and unidirectional material conveying is arranged above the lower-layer conveying and feeding mechanism.

[0006] As a preference, the lower-layer conveying and feeding mechanism is a belt conveyor. Anti-slip protrusions are uniformly fixed on the outer periphery of the belt of the belt conveyor. The belt conveyor has a simple structure. The anti-slip protrusions can prevent the material from sliding relative to the belt conveyor when supporting and conveying the material, affecting the conveying accuracy. A one-way bearing is installed on the belt conveyor. All the lower-layer conveying and feeding mechanisms use one-way bearings, which can only move forward and cannot move backward, preventing the lower-layer conveying and feeding mechanism from moving backward and realizing precise cutting.

[0007] As a preference, the upper-layer pressing and conveying mechanism includes a conveying chain. A plurality of anti-slip teeth are uniformly fixed on the outer periphery of the conveying chain. The two ends of the conveying chain are connected with a lower pressing sprocket and a driving sprocket. The conveying structure is simple and practical. The top of the material is pressed and grasped by the anti-slip teeth, and then through the rotation of the conveying chain, it cooperates with the lower-layer conveying and feeding mechanism to complete precise conveying and cutting, realizing almost no remaining meat heads. One-way bearings are installed on both the lower pressing sprocket and the driving sprocket, which can only move forward and cannot move backward, preventing the conveying chain from moving backward and realizing precise cutting.

[0008] As a preference, the bottom of the conveying chain below the lower pressing sprocket is lower than the conveying chain below the driving sprocket, which can better press down the conveyed material.

[0009] As a preference, there are multiple conveying chains. A bracket is rotatably installed on the lower pressing sprocket of each conveying chain. A guiding pull rod is rotatably installed on the upper part of each bracket. A spring is sleeved on the guiding pull rod. There is a fixing plate above the spring. Multiple strip-shaped holes for the top of the guiding pull rod to pass through are provided on the fixing plate. A limiting cap is fixed on the top of the guiding pull rod. The rear part of each bracket is rotatably installed on the fixing plate. Multiple conveying chains can better press down and grip the material. The lower pressing sprocket of each conveying chain can rotate around the rotating shaft rotatably installed at the rear part on the fixing plate, and through the guiding pull rod and spring at the top, buffering can be carried out to better press the material.

[0010] As a preference, a fixing frame is fixed on the feeding platform. The fixing plate is fixedly connected with a supporting frame. An adjusting device for adjusting the height of the supporting frame is provided on the fixing frame. The adjusting device includes a lifting screw rod threadedly installed on the fixing frame. The bottom of the lifting screw rod is rotatably installed on the supporting frame. A guide sleeve is fixed on the outside of the supporting frame. A guide rod is arranged in the guide sleeve. The top of the guide rod is fixed to the fixing frame, and the bottom of the guide rod is fixed to the feeding platform. The height of the upper pressing and conveying mechanism can be adjusted according to the height of the material, so as to adapt to the conveying of materials with different thicknesses.

[0011] As a preference, a strip-shaped tension adjusting groove is provided at the rear part of the supporting frame. A supporting shaft is arranged in the tension adjusting groove. Multiple driving sprockets are rotatably installed on the supporting shaft. Adjusting bolts extending into the tension adjusting groove to adjust the position of the supporting shaft in the tension adjusting groove are threadedly connected to both ends of the supporting shaft, which can conveniently tension the conveying chain.

[0012] As a preference, multiple guiding shafts are installed on the supporting frame and the fixing plate. Multiple guiding sprockets cooperating with the corresponding conveying chains are fixed on each guiding shaft. One of the guiding shafts is fixedly connected with an upper pressing and conveying motor, which is convenient for driving the guiding and conveying chain.

[0013] The present utility model also provides a meat slicer, which includes a meat slicing frame. A meat slicing mechanism is provided on the meat slicing frame. It also includes the above-mentioned continuous feeding mechanism. The continuous feeding mechanism is arranged beside the meat slicing mechanism. The feeding platform of the continuous feeding mechanism is fixed on the meat slicing frame.

[0014] As a preference, the meat cutting mechanism includes a meat cutting knife mechanism and a meat cutting driving mechanism for driving the meat cutting knife mechanism to reciprocate up and down. The meat cutting knife mechanism includes a tool rest, on which a wear-resistant sleeve is installed. A meat cutting knife is installed on the tool rest. A guiding slide bar fixed to the meat cutting machine frame is arranged inside the wear-resistant sleeve. The meat cutting driving mechanism includes a meat cutting motor fixed to the meat cutting machine frame. Rocker arms are fixed to the output shafts at both ends of the meat cutting motor. The rocker arms are rotatably connected to a connecting rod. The connecting rod is rotatably connected to a lower pull rod. The lower pull rod is rotatably connected to an upper pull rod. The upper pull rod is fixed to the wear-resistant sleeve.

[0015] The utility model has the following beneficial effects:

[0016] During the processes of slicing, shredding, and dicing fat beef square bricks, meat blocks, and meat strips, the lower-layer conveying and feeding mechanism and the upper-layer pressing and conveying mechanism cooperate to achieve continuous feeding, greatly improving the production efficiency; the one-way bearings are used in both the upper and lower layer feeding mechanisms, which can only move forward and cannot move backward, preventing the upper and lower conveying mechanisms from moving backward, achieving precise cutting, with almost no remaining meat heads, greatly reducing losses, and improving the production efficiency of the equipment.
