Description

Technical Field

[0001] This invention relates to the technical field of food processing, and in particular to an automatic meat processing pounding machine. Background Technology

[0002] In the meat processing industry, meat tenderness is one of the core indicators that determines its edible quality. Currently, artificial tenderizing methods for meat are mainly divided into three categories: physical tenderizing, chemical tenderizing, and enzymatic tenderizing. Among them, physical tenderizing methods change the structure of muscle fiber tissue through methods such as pounding, stirring, chopping, pricking, and rolling, causing muscle fiber breakage and reducing the toughness of connective tissue, thereby increasing the contact area between meat and water and improving water absorption, thus achieving the purpose of tenderization. Pounding, as an important means of physical tenderizing, can not only effectively break the integrity of muscle fibers and destroy the muscle fiber membrane and endomysium, but also promote the depolymerization and dissolution of myosin under the action of salt solution, so that the meat forms a good gel network structure, giving the product excellent elasticity and taste.

[0003] Existing meat processing pounding machines generally use crank-connecting rod mechanisms or cylinders to drive the hammer to reciprocate vertically. However, the hammer can only complete one effective pounding operation in each cycle. That is, when the hammer goes down, it pounds the meat in the tray, while when it goes up, it is an unloaded return motion and cannot generate processing efficiency. This pounding mode is inefficient. At the same time, during the return stroke, the equipment also needs to overcome the hammer's upward inertia and drive it to move down again. This periodic alternating inertial load not only subject the drive motor and transmission components to impact torque for a long time, causing fatigue wear and premature damage to key parts such as bearings and connecting rods, but also consumes a certain amount of energy each time it changes direction, which greatly reduces the economic efficiency of the equipment operation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an automatic meat processing pounding machine, the specific technical solution of which is as follows: An automatic meat processing pounding machine of the present invention includes: A storage bin with its opening facing upwards is used to hold meat materials. A bearing surface is provided on the inner side wall of the storage bin. The cross-sectional shape of the bearing surface is arc-shaped, and the arc-shaped opening is horizontally oriented towards the axis of the storage bin. A pounding unit is installed inside the storage tank. When the storage tank is rotating, it pounds the meat material located on the bearing surface. The unit includes several guide grooves, sliding columns slidably installed in each of the guide grooves, and a pounding body. The guide grooves intersect at a point to form a star-shaped structure, and the intersection point coincides with the midpoint of the guide groove. The sliding column reciprocates in the corresponding guide groove and pounds the meat material through the pounding body. The material collection unit is fixed relative to the guide trough plate. When the storage bucket rotates, the material collection unit gathers the meat material on the bearing surface.

[0005] Furthermore, the hammering unit also includes a main shaft, a connecting arm, and a star wheel. The connecting arm connects the main shaft and the star wheel, and the star wheel is connected to the middle of each of the sliding columns. During the rotation of the main shaft, the connecting arm uses the star wheel to drive each of the sliding columns to reciprocate within the corresponding guide groove plate, and adjacent sliding columns guide and restrict each other.

[0006] Furthermore, the number of the hammer body is set to one, the main shaft drives the hammer body to rotate synchronously through the auxiliary arm, and when the hammer body is squeezed at the end of the slide column, the auxiliary arm moves radially along the main shaft, and the auxiliary arm is connected to the main shaft through a spring.

[0007] Furthermore, the number of the hammering bodies is set to multiple, and each hammering body corresponds to the end of each guide groove plate; The multiple pounding bodies are divided into two groups. One group is used to pound the meat material on the bearing surface and has several protrusions on it. The other group is used to crush the meat material on the bearing surface. The hammer body is slidably mounted on the guide groove plate via a sliding body, and the hammer body and the guide groove plate are connected by an elastic rope.

[0008] Furthermore, the connecting arm is arranged to move radially along the main shaft.

[0009] Furthermore, the star wheel includes a connecting sleeve rotatably connected to the end of the connecting arm and a plurality of telescopic rods arranged along the circumference of the connecting sleeve. The telescopic rods are rotatably connected to the corresponding sliding column, and the movable end and the fixed end of the telescopic rods are connected by a spring piece.

[0010] Furthermore, each end of the sliding column is provided with a top column, and the top column is connected to the sliding column by a spring.

[0011] Furthermore, the material collection unit includes two opposing spiral blades, the ends of which scoop up the meat material on the bearing surface, and the sidewalls of which guide the meat material toward the space between the two spiral blades.

[0012] The beneficial effects of this invention are as follows: By driving the sliding column to reciprocate on the guide groove plate, both ends of the sliding column can pound the meat material, thereby increasing the pounding frequency of one cycle of the sliding column and improving work efficiency. At the same time, since the sliding column does not need to be provided with a driving force to overcome the inertia of motion, the long-term impact torque and energy loss of various structures in the equipment can be reduced, thus improving the service life of the equipment.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 10 As shown, an automatic meat processing pounding machine of the present invention includes: The storage bin 1 has an opening facing upwards and is used to hold meat materials. The inner side wall of the storage bin 1 is provided with a bearing surface 2. The cross-sectional shape of the bearing surface 2 is arc-shaped, and the arc-shaped opening is horizontally oriented towards the axis of the storage bin 1. The pounding unit 3 is installed inside the storage tank 1. When the storage tank 1 is rotating, it pounds the meat material located on the bearing surface 2. It includes several guide groove plates 5, sliding columns 6 slidably installed in each guide groove plate 5, and pounding body 7. The several guide groove plates 5 intersect at one point and form a star-shaped structure, and the intersection point coincides with the midpoint of the guide groove plate 5. The sliding column 6 reciprocates in the corresponding guide groove plate 5 and pounds the meat material through the pounding body 7. The material collection unit 4 is fixed relative to the guide trough plate 5. When the storage bucket 1 rotates, the material collection unit 4 gathers the meat material on the bearing surface 2.

[0019] Specifically, the storage bin 1 provides space for pounding meat materials, and the storage bin 1 can rotate under the drive of a motor. When the storage bin 1 rotates, the meat materials in the storage bin 1 can be gathered on the bearing surface 2 by centrifugal force. The arc-shaped setting of the bearing surface 2 can make the meat materials gather in the middle area of ​​the arc-shaped cross section of the bearing surface 2. That is, the pounding position of the meat materials is located on the side wall of the storage bin 1, rather than the lower inside of the storage bin 1.

[0020] Several guide plates 5 in the pounding unit 3 are on the same horizontal plane, and the midpoints of the guide plates 5 overlap to form an intersection. The angles between adjacent guide plates 5 are equal, thus forming a star-shaped structure. The sliding columns 6 in the guide plates 5 can reciprocate in different directions, thereby pounding the meat material at different positions on the bearing surface 2. Combined with the rotation of the storage bucket 1, the meat material in the storage bucket 1 is pounded comprehensively and continuously. Since the guide plates 5 intersect at one point, when one sliding column 6 passes through the intersection, the other sliding columns 6 are located away from the intersection. This can prevent the sliding columns 6 from colliding and getting stuck. That is, when the sliding columns 6 move in the corresponding guide plates 5, they need to reciprocate in sequence.

[0021] In use, meat is poured into storage bin 1, and the storage bin 1 is driven to rotate, causing the meat to gather on the bearing surface 2 by centrifugal force. Taking a guide plate 5 and a sliding column 6 as an example, when the sliding column 6 moves to one side on the guide plate 5, one end of the sliding column 6 can pound and squeeze the meat on the bearing surface 2 through the hammer body 7. When the sliding column 6 moves to the other side on the guide plate 5, the other end of the sliding column 6 can pound and squeeze the meat through the hammer body 7. This allows the sliding column 6 to perform two pounding operations in one motion cycle, while eliminating the need for additional pounding. The inertia of column 6 provides a reverse driving force; when several sliding columns 6 on several guide trough plates 5 reciprocate in sequence, each end of several sliding columns 6 can pound meat materials at different positions on the bearing surface 2 through the pounding body 7, thereby increasing the pounding frequency; during the rotation of storage bucket 1, the collecting unit 4 can gather the pounded and dispersed meat materials towards the center of the bearing surface 2. Of course, in order to support the collecting unit 4, a supporting column can be set in the center of storage bucket 1, storage bucket 1 is rotatably mounted on the supporting column, and the collecting unit 4 is fixed on the supporting column.

[0022] It should be noted that since both ends of the sliding column 6 can perform hammering operations, the material needs to be concentrated on the bearing surface 2 by centrifugal force to match the movement trajectory and working mode of the sliding column 6. To avoid the material sticking to the bottom of the storage tank 1, the material can be directly fed towards the bearing surface 2 during feeding, or oils such as edible oil can be added to the storage tank 1 to reduce material friction, or common auxiliary structures such as push scrapers can be installed at the bottom of the storage tank 2. These can all achieve the function of gathering the material towards the bearing surface. To prevent the material from falling directly onto the hammering unit, or to prevent the hammering unit from obstructing the movement of the material, in some embodiments, the feeding position can be adjusted, or a cone-shaped guide structure can be set above the hammering unit to guide the material to the bearing surface, so that the structure can operate normally.

[0023] By driving the sliding column 6 to reciprocate on the guide groove plate 5, both ends of the sliding column 6 can pound the meat material, thereby increasing the pounding frequency of the sliding column 6 in one motion cycle and improving work efficiency. At the same time, since the sliding column 6 does not need to be provided with a driving force to overcome the inertia of motion, the long-term impact torque and energy loss of various structures in the equipment can be reduced, thus improving the service life of the equipment.

[0024] Furthermore, the hammering unit 3 also includes a main shaft 8, a connecting arm 9, and a star wheel 10. The connecting arm 9 connects the main shaft 8 and the star wheel 10. The star wheel 10 is connected to the middle of each sliding column 6, so that during the rotation of the main shaft 8, the connecting arm 9 uses the star wheel 10 to drive each sliding column 6 to reciprocate within the corresponding guide groove plate 5, and adjacent sliding columns 6 guide and restrict each other.

[0025] Star wheel 10 connects each sliding column 6, and the connection positions of each sliding column 6 on star wheel 10 form a polygon. For example, when there are three sliding columns 6, they can form a triangle; when there are four sliding columns 6, they can form a quadrilateral. The center point of this polygon is rotatably connected to the end of connecting arm 9. The extension line of the axis of the main shaft 8 passes through the midpoint of guide groove plate 5. When the main shaft 8 rotates, it can rotate by connecting arm 9 to actuate star wheel 10. Star wheel 10 drives several sliding columns 6 to reciprocate within the corresponding guide groove plate 5. Specifically, taking the sliding column 6 closest to the diameter of the main shaft 8 where connecting arm 9 is located as an example, when star wheel 10 rotates around the axis of the main shaft 8, the angle between the line connecting the end of connecting arm 9 and the sliding column 6 and the straight line of connecting arm 9 is greater than 90 degrees. At this time, the rotation of the main shaft 8 can drive the sliding column 6 to slide within the corresponding guide groove plate 5. When the sliding column 6 moves away from the main shaft 8, star wheel 10 rotates synchronously on connecting arm 9. The rotation direction of shaft 8, with the assistance of star wheel 10, pushes the sliding column 6 on the front side of the sliding column 6 to move synchronously away from the main shaft 8. The sliding column 6 on the rear side of the sliding column 6 is pulled by star wheel 10 to move towards the main shaft 8. That is, adjacent sliding columns 6 guide and restrict each other. When the line connecting the end of the sliding column 6 and the end of the connecting arm 9 is collinear with the straight line of the connecting arm 9, the sliding column 6 moves outward to the farthest position. Then, the movement of star wheel 10 will pull the sliding column 6 to move towards the main shaft 8. When the sliding column 6 passes the midpoint of the guide groove plate 5 and moves to the other side of the guide groove plate 5, since star wheel 10 connects each sliding column 6 and several sliding columns 6 guide and restrict each other through star wheel 10, the sliding column 6 is prevented from getting stuck at the midpoint of the guide groove plate 5, ensuring that the sliding column 6 can move smoothly towards the other side of the guide groove plate 5. At this time, the sliding column 6 moves away from the main shaft 8. This process is repeated. By using the rotational motion of the main shaft 8, several sliding columns 6 can be driven to reciprocate in sequence and continuously.

[0026] Furthermore, the number of hammer bodies 7 is set to one. The main shaft 8 drives the hammer body 7 to rotate synchronously through the auxiliary arm 14. When the hammer body 7 is squeezed at the end of the slide column 6, the auxiliary arm 14 moves radially along the main shaft 8. The auxiliary arm 14 and the main shaft 8 are connected by a spring 15.

[0027] like Figure 4As shown, when the number of pounding bodies 7 is set to one, in order for the ends of each sliding column 6 to cooperate with the pounding body 7, the pounding body 7 needs to rotate synchronously with the main shaft 8, that is, along the circumferential direction of the main shaft 8, the pounding body 7 and the connecting arm 9 are relatively stationary; when the pounding body 7 approaches the end of the guide groove plate 5, the sliding column 6 in the guide groove plate 5 moves outward synchronously, and the end of the sliding column 6 will contact the pounding body 7 and push the pounding body 7 towards the meat material on the bearing surface 2 to pound and squeeze it. At this time, the auxiliary arm 14 slides on the main shaft 8, and when the connecting arm When the slide column 6 is parallel to the guide groove plate 5, it moves outward the furthest distance. Then the slide column 6 moves in the opposite direction. The spring 15 pulls the hammer body 7 back to its original position through the auxiliary arm 14. When the slide column 6 moves back into the area where the guide groove plate 5 is located, the end of the slide column 6 separates from the hammer body 7. The hammer body 7 follows the main shaft 8 to rotate to the end of the next guide groove plate 5. This allows one hammer body 7 to be used in conjunction with the ends of several slide columns 6. Since the hammer body 7 moves synchronously with the main shaft 8, it slides relative to the end of the slide column 6 when it contacts the end of the slide column 6 in the circumferential direction of the main shaft 8.

[0028] In some embodiments, the storage hopper 1 and the main shaft 8 move at different speeds, and the pounding body 7 moves relative to the bearing surface 2 when pounding the meat material, thereby causing the pounding body 7 to form a crushing effect on the meat material.

[0029] Furthermore, the number of hammer bodies 7 is set to multiple, and each hammer body 7 corresponds to the end of each guide groove plate 5; Multiple hammers 7 are divided into two groups. One group is used to hammer the meat material on the bearing surface 2 and has several protrusions 20 on it. The other group is used to crush the meat material on the bearing surface 2. The hammering body 7 is slidably mounted on the guide groove plate 5 via the sliding body 18, and the hammering body 7 and the guide groove plate 5 are connected by an elastic rope 21.

[0030] like Figure 3 As shown, each guide groove plate 5 is fitted with a pounding body 7 at its end. This way, the pounding body 7 can be moved along the length of the guide groove plate 5 to meet the pounding requirements of the meat material at both ends of each slide column 6. That is, the pounding body 7 does not need to rotate with the main shaft 8.

[0031] To improve the pounding effect, the pounding body 7 can be divided into two groups: a group of pounding plates 16 and a group of rolling plates 17. The pounding plates 16 can be used to pound meat materials, and the rolling plates 17 can be used to roll meat materials. Both the pounding plates 16 and the rolling plates 17 are slidably set on the guide groove plate 5 via corresponding sliding bodies 18. Specifically, the end of the sliding body 18 on the pounding plate 16 is provided with a side rail 19. The pounding plate 16 is slidably set on the side rail 19 along the circumferential direction of the main shaft 8. The protrusion 20 is set on the working surface of the pounding plate 16. When the sliding column 6 pushes the pounding plate 16 to pound the meat on the bearing surface 2... When the material is being pounded, the protrusions 20 on the pounding plate 16 can improve the pounding effect. The friction between the bearing surface 2, the material and the pounding plate 16 will cause the pounding plate 16 to slide on the side rail 19. The pounding plate 16 and the bearing surface 2 are relatively stationary, so the pounding plate 16 only pounds the material. When the sliding column 6 moves in the opposite direction, the pounding plate 16 separates from the bearing surface 2 and the material. The rolling plate 17 will be pushed by the sliding column 6 and directly pound the material. The rolling plate 17 cannot rotate with the main shaft 8, so the rolling plate 17 and the bearing surface 2 will move relative to each other. The rolling plate 17 has a rolling effect on the material.

[0032] To facilitate the resetting of the hammer plate 16 and the rolling plate 17, each hammer body 7 is equipped with an elastic pull rope 21. The rolling plate 17 is connected to the corresponding guide groove plate 5 through the elastic pull rope 21, and the hammer plate 16 is connected to the corresponding guide groove plate 5 through the elastic pull rope 21. Furthermore, the bottom of the sliding body 18 on the hammer plate 16 is provided with a reversing column 22, and the elastic pull rope 21 passes around the reversing column 22. In this way, when the hammer plate 16 moves on the side rail 19, or when the sliding body 18 on the hammer plate 16 moves on the guide groove plate 5, the elastic pull rope 21 can provide a resetting elastic force for both the hammer plate 16 and the sliding body 18.

[0033] Furthermore, the connecting arm 9 is arranged to move radially along the main shaft 8.

[0034] The end of the connecting arm 9 away from the star wheel 10 can slide through the main shaft 8. The main shaft 8 and the connecting arm 9 are fastened together by a set screw. So when it is necessary to adjust the position of the connecting arm 9 on the main shaft 8, simply loosen the set screw and pull the connecting arm 9. When the connecting arm 9 moves on the main shaft 8, the distance between the star wheel 10 and the main shaft 8 changes, thereby adjusting the rotation radius of the star wheel 10 and the farthest distance that the slide column 6 moves outward, which makes it easy to adjust the hammering depth of the hammer body 7 on the material.

[0035] Furthermore, the star wheel 10 includes a connecting sleeve 11 rotatably connected to the end of the connecting arm 9 and a plurality of telescopic rods 12 arranged along the circumferential direction of the connecting sleeve 11. The telescopic rods 12 are rotatably connected to the corresponding sliding column 6, and the movable end and the fixed end of the telescopic rod 12 are connected by a spring piece 13.

[0036] When the distance between the connection points of two adjacent sliding pins 6 on the star wheel 10 is constant, the movement trajectory of the star wheel 10 is fixed, and the distance between the end of the connecting arm 9 and the main shaft 8 is fixed. However, if the distance between the end of the connecting arm 9 and the main shaft 8 is adjusted, then the distance between the connection points of two adjacent sliding pins 6 on the star wheel 10 needs to be changed synchronously. Specifically, for example... Figure 6 As shown, the telescopic rod 12 located on the side of the connecting arm 9 is in a stretched state, and the elastic piece 13 on it undergoes elastic deformation. Meanwhile, the telescopic rod 12 parallel to the connecting arm 9 is in a contracted state. As the distance between the end of the connecting arm 9 and the main shaft 8 increases, the telescopic rod 12 parallel to the connecting arm 9 and the corresponding sliding rod 6 will move a certain distance away from the main shaft 8, thereby increasing the range of motion of the sliding rod 6. When the main shaft 8 rotates, the telescopic rod 12 located in front of the connecting arm 9 will gradually contract along the rotation direction of the main shaft 8, and the telescopic rod 12 originally parallel to the connecting arm 9 will gradually stretch. Thus, the normal operation of the structure is ensured even when the position of the connecting arm 9 is changed.

[0037] Furthermore, each end of the sliding column 6 is provided with a top column 23, and the top column 23 is connected to the sliding column 6 by a spring 24.

[0038] When the end of the sliding column 6 moves toward the hammer body 7 and comes into contact with it, the hammer body 7 is stationary along the length of the guide groove plate 5. Therefore, in order to reduce the impact intensity of the sliding column 6 on the hammer body 7, the top column 23 and the spring 24 can be used to buffer the sliding column 6 and the hammer body 7.

[0039] It should be noted that when the hammer body 7 is pressing and hammering the material, the second spring 24 is compressed. The way the connecting arm 9 is positioned on the main shaft 8 can be used to adjust the amount of compression of the second spring 24 when the hammer body 7 is in the hammering position, thereby adjusting the hammering force of the hammer body 7 on the material.

[0040] Furthermore, the material collection unit 4 includes two opposing spiral blades 25. The ends of the spiral blades 25 scoop up the meat material on the bearing surface 2, and the sidewalls of the spiral blades 25 guide the meat material toward the space between the two spiral blades 25.

[0041] One end of the spiral blade 25 is in line contact with the bearing surface 2, while the other end of the spiral blade 25 is separated from the bearing surface 2. The extension line of this end of the spiral blade 25 is in point contact with the bearing surface 2. This causes the surface on the spiral blade 25 to gradually tilt towards the area between the two spiral blades 25 along the length of the spiral blade 25. When the storage bucket 1 rotates, the pounding of the material by the hammer body 7 will cause the material to disperse in the vertical direction. The end of the spiral blade 25 can scoop up the dispersed material and use the guiding effect of the surface of the spiral blade 25 to make the material gather between the two spiral blades 25. This allows the material to move back to the middle area of ​​the bearing surface 2, making it easier for the hammer body 7 to continuously pound the material. When the number of hammer bodies 7 is set to one, the spiral blade 25 rotates synchronously with the main shaft 8. When the number of hammer bodies 7 is set to multiple, the spiral blade 25 is fixedly set relative to the guide groove plate 5, and the spiral blade 25 is located between two adjacent hammer bodies 7.

[0042] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
