Abstract
Description
Technical Field
[0001] This invention relates to the field of meat chopper technology, and more particularly to a meat chopper for preparing meat products. Background Technology
[0002] In the field of industrialized meat processing, meat choppers are the core equipment in the production process of meat products (such as sausages, meatballs, luncheon meat, and seasoned minced meat). They are mainly used to chop, mix, and emulsify raw materials such as meat chunks, fat, and auxiliary materials at high speed, so that the minced meat is fine, uniform, elastic, and has a good taste, which directly determines the quality and yield of meat products.
[0003] Existing traditional chopping machines generally suffer from the following technical defects: 1. Limited chopping method: Mostly uses single-layer or same-plane rotating chopping blades, which can only achieve horizontal cutting. It does not cut deep or bottom raw materials sufficiently, which can easily lead to uneven particle size, clumping, and incomplete chopping. The emulsification effect is poor, which affects the elasticity and fineness of meat products.
[0004] 2. Low loading and unloading efficiency and insufficient safety: Most equipment relies on manual labor or simple pushing mechanisms to load and unload material boxes, which is cumbersome and labor-intensive. Inaccurate positioning of material boxes can easily lead to blade collisions and material spillage, posing safety hazards. Summary of the Invention
[0005] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a meat chopper for seasoning meat products, which effectively solves the problems of single chopping method, low loading and unloading efficiency, and insufficient safety in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A meat chopper for seasoning meat products includes a support base, a chopping box fixedly installed on the upper end of the support base, a through hole at the lower end of the chopping box, a chopping body slidably disposed within the through hole, a mounting base fixedly installed on the support base, a feeding structure disposed on the mounting base, the feeding structure including a support frame that moves vertically downward and then horizontally, the support frame being fixedly welded to the bottom of the chopping body, a chopping structure disposed inside the chopping box, the chopping structure including a first rotating rod and a second rotating rod rotatably connected to the chopping box, a plurality of first chopping blades disposed inside the chopping body being fixedly connected to the first rotating rod, and a second chopping blade disposed on the second rotating rod that rotates on its own axis and moves intermittently up and down and is disposed alternately with the first chopping blades.
[0007] Preferably, the chopping structure further includes a first motor fixedly installed on the upper end of the chopping box, the output end of the first motor is equipped with the first rotating rod, the upper end of the first rotating rod is fixedly connected to a first pulley, the first pulley is connected to a second pulley, and the second pulley is fixedly installed on the second rotating rod.
[0008] Preferably, the lower end of the first pulley is provided with a cam that is fixedly connected to the first rotating rod, the lower end of the second pulley is provided with a second inner ring wheel that is fixedly connected to the second rotating rod, a limiting slide is slidably provided on the second inner ring wheel, one end of the limiting slide is fixedly installed with a limiting rod that is slidably connected to the inner wall of the chopping box, and the other end of the limiting slide is rotatably connected with an extrusion wheel corresponding to the cam.
[0009] Preferably, the upper end of the extrusion wheel is provided with a second rotating shaft block that is fixedly connected to the limiting slide, the upper end of the cam is provided with a first rotating shaft block that is rotatably connected to the first rotating rod, a column is fixedly connected to the first rotating shaft block, and a column rod that is slidably disposed with the inner wall of the column is fixedly connected to the second rotating shaft block. A spring is sleeved and connected to the column and the column rod, and the two ends of the spring are fixedly connected to the first rotating shaft block and the second rotating shaft block respectively.
[0010] Preferably, a connecting rod is rotatably connected to the limiting slide, a second pin is fixedly installed at the lower end of the connecting rod, a first inner ring wheel is provided at the lower end of the limiting slide and sleeved with the second rotating rod, the second pin is located in the annular groove of the first inner ring wheel, a fixing rod is fixedly connected to the lower end of the first inner ring wheel, the second chopping blades are all fixedly mounted on the fixing rod, and a spline is also provided on the second rotating rod that is vertically limited and slidably configured with the first inner ring wheel and the second chopping blade.
[0011] Preferably, the feeding structure further includes a second motor fixedly mounted on the mounting base plate. The output end of the second motor is fixedly mounted with a driving bevel gear, which meshes with a driven bevel gear. The driven bevel gear is coaxially fixedly connected to a rotating rod. An L-shaped groove is provided on the mounting base plate. A first pin is provided in the rotating rod and slidably connected to the L-shaped groove. The first pin is fixedly mounted on the support frame.
[0012] Preferably, a limiting slide plate is horizontally slidably disposed on the support base, and the inner wall of the limiting slide plate is vertically slidably connected to the support frame.
[0013] Preferably, both the first and second chopping blades are multi-bladed arc blades, and they are arranged alternately in the vertical direction to form a three-dimensional chopping area.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. While rotating with the second rotating rod, the second chopping blade achieves a controllable up-and-down reciprocating motion, forming a dynamic staggered cutting with the first chopping blade at a fixed height. This expands the three-dimensional chopping range and completely solves the problems of uneven chopping, bottom clumping, and insufficient emulsification in traditional methods. Furthermore, when the first and second chopping blades move close together and intertwine, their blade surfaces scrape against each other, forcibly peeling off and scraping away the meat residue, tendons, and fat adhering to the blades and surfaces. This prevents the meat from continuously adhering and accumulating, keeping the blade surfaces clean and the blades sharp.
[0015] 2. During the rotation of the rotating rod, the sliding groove at its front end can drive the first pin to move along the inner wall of the L-shaped groove in an L-shaped trajectory. Then, the first pin drives the support frame to move vertically first and then horizontally. The support frame drives the chopping box to move vertically downward until it is separated from the chopping box, and then moves horizontally. The horizontal movement of the chopping box moves it out of the lower end of the support base, which facilitates loading and unloading. Since the vertical height of the L-shaped groove is fixed, it can effectively avoid the chopping box from being mispositioned, which could lead to blade collision. Attached Figure Description

[0017] like Figure 1-8 As shown, a meat chopper for seasoning includes a support base 3. A chopping box 1 is fixedly installed on the upper end of the support base 3. A through hole is provided at the lower end of the chopping box 1, and a chopping box body 28 is slidably disposed in the through hole. A mounting base 4 is fixedly installed on the support base 3. A feeding structure is provided on the mounting base 4. The feeding structure includes a support frame 26 that moves vertically downward and then horizontally. The support frame 26 is fixedly welded to the bottom of the chopping box body 28. A chopping structure is provided inside the chopping box 1. The chopping structure includes a first rotating rod 11 and a second rotating rod 15 that are rotatably connected to the chopping box 1. A plurality of first chopping blades 19 disposed in the chopping box body 28 are fixedly connected to the first rotating rod 11. A second chopping blade 20 is disposed on the second rotating rod 15 that rotates on its own axis and moves up and down intermittently and is installed alternately with the first chopping blades 19.
[0018] The chopping structure also includes a first motor 2 fixedly installed on the upper end of the chopping box 1. The output end of the first motor 2 is equipped with the first rotating rod 11. The upper end of the first rotating rod 11 is fixedly connected to a first pulley 13. The first pulley 13 is connected to a second pulley 14. The second pulley 14 is fixedly installed on the second rotating rod 15.
[0019] like Figure 1 and 3 As shown, the first motor 2 is working, and the output end of the first motor 2 drives the first rotating rod 11 to rotate. The first rotating rod 11 drives the first pulley 13 to rotate. The first pulley 13 drives the second pulley 14 to rotate through the transmission belt. The second pulley 14 drives the second rotating rod 15 to rotate synchronously with the first rotating rod 11.
[0020] The lower end of the first pulley 13 is provided with a cam 12 fixedly connected to the first rotating rod 11. The lower end of the second pulley 14 is provided with a second inner ring wheel 21 fixedly connected to the second rotating rod 15. A limiting slide 16 is slidably provided on the second inner ring wheel 21. One end of the limiting slide 16 is fixedly installed with a limiting rod 17 slidably connected to the inner wall of the chopping box 1. The other end of the limiting slide 16 is rotatably connected with a pressing wheel 22 corresponding to the cam 12.
[0021] like Figure 3 and 4 As shown, the first rotating rod 11 drives the cam 12 to rotate. During the rotation of the cam 12, it will intermittently squeeze the extrusion wheel 22. After the extrusion wheel 22 is subjected to force, it drives the limiting slide 16 to slide horizontally along the inner ring groove of the second inner ring wheel 21. At the same time, the limiting slide 16 drives the limiting rod 17 to slide horizontally along the inner wall of the chopping box 1, ensuring the stable sliding of the limiting slide 16 in the horizontal direction.
[0022] The upper end of the extrusion roller 22 is provided with a second rotating shaft block 24 fixedly connected to the limiting slide 16. The upper end of the cam 12 is provided with a first rotating shaft block 23 rotatably connected to the first rotating rod 11. A column cylinder 33 is fixedly connected to the first rotating shaft block 23. A column rod 34 slidably connected to the inner wall of the column cylinder 33 is fixedly connected to the second rotating shaft block 24. A spring 25 is sleeved and connected to the column cylinder 33 and the column rod 34. The two ends of the spring 25 are fixedly connected to the first rotating shaft block 23 and the second rotating shaft block 24, respectively.
[0023] like Figure 4 and 5 As shown in Figure 8, during the horizontal reciprocating sliding of the limiting slide 16, the second rotating shaft block 24 is driven to move. The first rotating shaft block 23 is used to install and fix the column cylinder 33, and the second rotating shaft block 24 is used to install and fix the column rod 34. The second rotating shaft block 24 drives the column rod 34 to slide horizontally and reciprocatingly along the inner wall of the column cylinder 33. At the same time, the spring 25 is repeatedly compressed, and the spring 25 plays a role in resetting the limiting slide 16.
[0024] A connecting rod 30 is rotatably connected to the limiting slide 16. A second pin 31 is fixedly installed at the lower end of the connecting rod 30. A first inner ring wheel 18 is provided at the lower end of the limiting slide 16 and is sleeved and connected to the second rotating rod 15. The second pin 31 is located in the annular groove of the first inner ring wheel 18. A fixing rod 29 is fixedly connected to the lower end of the first inner ring wheel 18. The second chopping blades 20 are all fixedly installed on the fixing rod 29. A spline 32 is also provided on the second rotating rod 15 and is vertically limited and slidably configured with the first inner ring wheel 18 and the second chopping blades 20.
[0025] like Figure 4 and 5As shown, during the horizontal reciprocating motion of the limiting slide 16, the connecting rod 30 is deflected. During this deflection, the change in length of the connecting rod 30 drives the first inner ring wheel 18 to slide up and down along the second rotating rod 15 via the second pin 31. Since the first chopping blade 19 is fixedly mounted on the first rotating rod 11, the reciprocating up and down sliding of the first inner ring wheel 18 drives the lower second chopping blade 20 to move up and down via the fixed rod 29, thus changing the distance between the first chopping blade 19 and the second chopping blade 20. By setting the spline 32, the distance between the first inner ring wheel 18 and the second chopping blade 20 can be maintained. During the rotation of the second chopping blade 20, it can move up and down. While rotating with the second rotating rod 15, the second chopping blade 20 achieves controllable up-and-down reciprocating motion, forming a dynamic staggered cutting with the first chopping blade 19 at a fixed height, expanding the three-dimensional chopping range, and completely solving the problems of uneven chopping, bottom clumping, and insufficient emulsification in traditional methods. When the first chopping blade 19 and the second chopping blade 20 move close to each other, the blade surfaces scrape against each other, which can forcibly peel off and scrape off the meat paste, tendons, and fat adhering to the blade and blade surface, preventing the meat from continuously adhering and accumulating, keeping the blade surface clean and the blade sharp.
[0026] The feeding structure also includes a second motor 5 fixedly mounted on the mounting base plate 4. The output end of the second motor 5 is fixedly mounted with a driving bevel gear 6. The driving bevel gear 6 meshes with a driven bevel gear 7. The driven bevel gear 7 is coaxially fixedly connected to a rotating rod 8. An L-shaped groove 10 is opened on the mounting base plate 4. A first pin 9 is provided in the rotating rod 8 and slidably connected to the L-shaped groove 10. The first pin 9 is fixedly mounted on the support frame 26.
[0027] like Figure 6 and 7 As shown, the mounting base 4 serves to install and fix the second motor 5. The output end of the second motor 5 drives the active bevel gear 6 to rotate, which in turn drives the driven bevel gear 7 to rotate. The driven bevel gear 7 drives the rotating rod 8 to rotate. During its rotation, the sliding groove at the front end of the rotating rod 8 can drive the first pin 9 to move along the inner wall of the L-shaped groove 10 in an L-shaped trajectory. Then, the first pin 9 drives the support frame 26 to move vertically first and then horizontally. The support frame 26 drives the chopping box 28 to move vertically downward until it is separated from the chopping box 1 and then moves horizontally. The chopping box 28 is moved horizontally out of the lower end of the support base 3, which facilitates loading and unloading. Since the vertical height of the L-shaped groove 10 is fixed, it can effectively prevent the chopping box 28 from being mispositioned and causing the blade to collide.
[0028] A limiting slide plate 27 is horizontally slidably disposed on the support base, and the inner wall of the limiting slide plate 27 is vertically slidably connected to the support frame 26.
[0029] like Figure 6 and 7As shown, the support frame 26 can form a composite limit of horizontal guidance and vertical sliding, ensuring that the support frame 26 and the chopping box 28 strictly follow the preset trajectory to complete the vertical downward movement and horizontal translation movement, improving the positioning accuracy and motion stability of the chopping box 28, avoiding interference between the cutting tool and the chopping box 28 caused by feeding deviation, and ensuring the safe and stable operation of the equipment.
[0030] Both the first chopping blade 19 and the second chopping blade 20 are multi-bladed arc blades, and they are arranged alternately in the vertical direction to form a three-dimensional chopping area.
[0031] like Figure 4 As shown, the first chopping blade 19 and the second chopping blade 20 form a three-dimensional chopping area with vertically intersecting, multi-bladed arc cutting, which expands the chopping coverage and eliminates the dead corners in the chopping box 28. The multi-bladed arc blades can improve cutting efficiency and the fineness of the minced meat. The alternating arrangement can ensure sufficient cutting and uniform mixing, avoid mutual interference between the blades, and achieve self-cleaning of the blade surface to prevent meat from sticking, thereby improving the overall chopping quality and equipment stability.
[0032] The working process of this invention is as follows: The second motor 5 is started, and the output end of the second motor 5 drives the active bevel gear 6 to rotate. The active bevel gear 6 meshes and drives the driven bevel gear 7 to rotate synchronously. The driven bevel gear 7 drives the rotating rod 8 to rotate. The sliding groove at the front end of the rotating rod 8 pushes the first pin 9 to move along the L-shaped groove 10 on the mounting base plate 4 in an L-shaped trajectory. The first pin 9 drives the support frame 26 and the bottom chopping box 28 to move vertically upward first, and enter the lower end through hole of the chopping box 1 to complete the positioning. The support frame 26 is constrained by the limiting slide plate 27 and can only move along the preset path to ensure that the chopping box 28 is accurately aligned and does not deviate, avoiding collision with the blade. After the material is loaded into place, the second motor 5 stops, and the chopping box 28 is fixed in the working position, ready to enter the chopping process.
[0033] The first motor 2 is started, and its output drives the first rotating rod 11 to rotate at high speed. The first chopping blade 19 on the first rotating rod 11 rotates synchronously, performing basic horizontal chopping. The first rotating rod 11 drives the first pulley 13 to rotate, and the first pulley 13 drives the second pulley 14 to rotate synchronously with the second rotating rod 15 through a transmission belt. The second rotating rod 15 drives the second chopping blade 20 to rotate through the spline 32. At the same time, the first rotating rod 11 drives the cam 12 to rotate. The cam 12 intermittently squeezes the extrusion wheel 22, pushing the limit slide 16 horizontally along the second inner ring wheel 21. The sliding mechanism 16 drives the connecting rod 30 to deflect. The connecting rod 30 pulls the first inner ring wheel 18 through the second pin 31, and slides up and down along the second rotating rod 15. The first inner ring wheel 18 drives the second chopping blade 20 through the fixed rod 29. While rotating, it moves up and down intermittently, forming a dynamic interlaced cutting with the first chopping blade 19 at a fixed height. When the first chopping blade 19 and the second chopping blade 20 move close to each other, the blade surfaces scrape and adhere to each other. The meat paste, tendons, and fat adhering to the blade and blade surface are forcibly peeled off and scraped off, returning to the chopping box 28.
[0034] After chopping is completed, the first motor 2 stops, and the blades stop rotating. The second motor 5 is restarted, and the rotating rod 8 drives the first pin 9 to move in the opposite direction along the L-shaped groove. The support frame 26 drives the chopping box 28 to first move vertically downwards away from the chopping box 1, and then move horizontally out of the support base 3. The operator can then directly pick up and unload the material.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
