Description

Technical Field

[0001] This invention relates to the field of meat processing technology, and in particular to a meat grinding device for meat processing and its usage method. Background Technology

[0002] In the meat processing industry, meat grinding equipment plays a crucial role. However, traditional meat grinding equipment has many limitations. For example, it has low grinding efficiency and often struggles to complete the processing task quickly and evenly when crushing meat products, resulting in production efficiency that cannot meet the needs of large-scale production. At the same time, meat scraps tend to adhere to the inner wall of the equipment during the grinding process, which not only affects the processing effect and efficiency to a certain extent but is also relatively difficult to clean, increasing the difficulty and cost of equipment maintenance. In addition, traditional meat grinders lack flexibility in discharge, making it difficult to easily adjust the discharge direction according to different production layouts and packaging requirements. Furthermore, when repairing and replacing internal parts after long-term use, it often requires disassembling a large number of other parts, which not only increases maintenance time and cost but also makes the operation complex and cumbersome, requiring a lot of time and manpower.

[0003] These problems have, to some extent, constrained the efficient development of the meat processing industry, and there is an urgent need for an innovative meat grinding equipment to solve the above dilemmas, thereby improving the overall quality and efficiency of meat processing and meeting the growing market demand and the stringent requirements of food safety standards. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by proposing a meat grinding device for meat product processing and its usage method.

A discharge pipe connected to the discharge cylinder is fixedly installed on the bottom outer side of the discharge cylinder. The rotating shaft is rotatably mounted on the meat grinder. In the center of the machine casing, multiple crushing blades are fixedly mounted on the rotating shaft and arranged radially. A support ring is rotatably mounted on the top side of the top cover, and the multiple crushing blades are fixedly connected to the support ring. The first crushing component is set on the rotating shaft. The second crushing component is set inside the meat grinder casing and connected to the support ring. The transmission component is set on the second crushing component and the top cover. The cleaning component is set on the outside of the support ring and adapted to the inner wall of the meat grinder casing. The limiting component is set on the discharge cylinder and connected to the bottom of the meat grinder casing.

[0008] Preferably, the opening and closing control assembly includes two electric cylinders, multiple fixing blocks, and two ear plates. Two ear plates are symmetrically fixedly installed on the outer side of the top cover. Multiple fixing blocks are fixedly installed on the outer side of the meat grinder casing. The same electric cylinder is fixedly installed on the multiple fixing blocks located on the same side. The working ends of the two electric cylinders are respectively fixedly connected to the corresponding ear plates.

[0009] Preferably, the crushing assembly includes multiple sliding sleeves and multiple crushing blades. Multiple annular grooves are provided on the outer side of the rotating shaft. Sliding sleeves are slidably installed in the multiple annular grooves along the axial direction of the rotating shaft. Multiple crushing blades are fixedly installed radially on the outer side of the sliding sleeves.

[0010] Preferably, the second crushing component includes multiple crushing blades (three) and multiple rotating rods. An annular groove is provided on the top side of the support ring. Multiple rotating rods parallel to the rotating shaft are rotatably mounted on the support ring. Multiple crushing blades (three) are radially fixedly mounted on each of the multiple rotating rods. The multiple crushing blades (three) are arranged in an alternating manner with the corresponding first crushing blades.

[0011] Preferably, the transmission assembly includes multiple transmission gears and a gear disc. The gear disc is fixedly installed on the bottom side of the top cover at the position corresponding to the annular groove, with the rotating shaft as the center. The top ends of multiple rotating rods extend into the annular groove and are respectively fixedly fitted with transmission gears. The multiple transmission gears mesh with the gear disc.

[0012] Preferably, the cleaning component includes a support block, a first scraper, a second scraper, and a connecting rod. The support block is radially fixedly installed on the outer side of the support ring. The first scraper is fixedly installed on the support block. The second scraper is fixedly installed at the bottom end of the first scraper. The second scraper and the rotating shaft are fixedly connected by the same connecting rod. Both the first scraper and the second scraper are in contact with the inner wall of the meat grinder housing, and the first scraper is arranged in a spiral shape.

[0013] Preferably, the discharge assembly includes a mandrel, spiral blades, and a motor. The bottom of the discharge cylinder is enclosed, and the motor is fixedly installed at the bottom of the discharge cylinder. The output shaft of the motor extends into the discharge cylinder and is axially fixedly connected to the mandrel. Spiral blades are fixedly installed on the mandrel. The top ends of both the mandrel and the spiral blades extend into the meat grinder housing, and the top end of the mandrel is detachably connected to the bottom end of the rotating shaft. The spiral blades are aligned with the spiral direction of the scraper.

[0014] Preferably, the bottom end of the rotating shaft has multiple slots, and the top end of the spindle is fixedly installed with a snap-fit ​​block. The snap-fit ​​block is snap-fitted into the slots, and the vertical projections of the slots and the snap-fit ​​block are both set in the shape of regular polygons.

[0015] Preferably, the limiting component includes a limiting rod, a mounting block, a rotating pin, and a torsion spring. The bottom of the meat grinder housing has multiple limiting grooves centered on the discharge cylinder. The mounting block is fixedly installed on the outer side of the discharge cylinder. A rotating pin is rotatably installed on the mounting block. A T-shaped limiting rod is radially fixedly installed on the rotating pin. A torsion spring is fixedly installed on the limiting rod centered on the rotating pin. The end of the torsion spring away from the limiting rod is fixedly connected to the mounting block, and the limiting rod is engaged in the corresponding limiting groove.

[0016] The present invention also provides a method for a meat grinding device for processing meat products, comprising the following steps:

[0017] S1: First, connect the power supply and start the motor. The motor drives the spindle to rotate in the opposite direction. With the cooperation of the locking block and the locking slot, it can drive the rotating shaft to rotate synchronously. The rotating shaft controls the rotation of the support ring through multiple crushing blades, so that multiple rotating rods rotate around the rotating shaft. At the same time, with the cooperation of the gear plate and the transmission gear, multiple rotating rods can maintain a state of rapid self-rotation. This allows the rotating shaft and the rotating rods to maintain a state of opposite rotation and control the corresponding crushing blades one and three to rotate. While the support ring rotates, the support block drives the spirally arranged scraper blades one and two to move along the inner wall of the meat grinder casing and achieve the cleaning function.

[0018] S2: The meat products to be processed are fed into the meat grinder housing through the feed cylinder, or a downward force is applied to the top of the meat after it is placed in the feed cylinder. When the meat products pass through multiple crushing blades, they are sliced ​​by the action of multiple crushing blades and fall into the working range of crushing blades one and three. Since the rotation speed of crushing blade three is greater than that of crushing blade one and rotates in the opposite direction, the meat products entering the meat grinder housing can be crushed quickly and efficiently. Inevitably, some meat scraps will be thrown onto the inner wall of the meat grinder housing. With the cooperation of the spirally arranged scraper blades one and two, they can be cleaned. The spirally arranged scraper blade one will scrape them upward, so that they can be crushed again by crushing blade three. Since crushing blade one is axially slidably installed in the annular groove on the rotating shaft through a sliding sleeve, crushing blade one will move up and down within the range of the annular groove under the influence of the meat products during the crushing process, thereby further improving the uniformity of crushing.

[0019] S3: When the meat products need to be discharged after processing, manually control the T-shaped limit rod and disengage it from the limit groove. Then rotate the discharge cylinder and adjust the discharge pipe to the desired discharge direction. Release the limit rod, and under the action of the torsion spring, it can be locked into the corresponding limit groove, thus preventing the discharge direction from deviating on its own during the discharge process. Then control the motor to rotate forward, so that the spiral blades can control the meat accumulated on the inner wall of the bottom of the meat grinder to be transported and discharged through the discharge cylinder to the discharge pipe. Since the spiral blades and scraper one are in the same spiral direction, scraper one scrapes the meat adhering to the inner wall of the meat grinder downward, and scraper two assists in sending it to the feeding position of the discharge cylinder. As the discharge continues, the amount of meat products in the meat grinder is reduced, so that most of the meat scraps on crushing blade one and crushing blade three will be thrown out under the action of centrifugal force.

[0020] When it is necessary to inspect or replace the parts inside the meat grinder, the ear plate is controlled by the electric cylinder to move the top cover upward, so that the slot on the rotating shaft can disengage from the locking block at the top of the spindle. At the same time, the rotating rod, support ring, crushing blade one, crushing blade two and crushing blade three, as well as scraper one and scraper two, will all move upward with the top cover, making it easier for technicians to carry out inspection or replacement of parts.

[0021] Compared with the prior art, the present invention provides a meat grinding device for meat product processing and its method of use, which has the following beneficial effects:

[0022] (1) The set crushing blade can preliminarily slice meat products. At the same time, the set crushing component one, crushing component two and transmission component can quickly and efficiently crush meat products. The discharge component, discharge cylinder and discharge pipe facilitate convenient discharge of processed meat products.

[0023] (2) The cleaning components can clean the meat scraps stuck to the inner wall of the meat grinder. Since the scraper in the cleaning components is spirally designed, it can scrape the meat scraps downwards and assist the discharge components in discharging the material when rotating in the forward direction. When rotating in the reverse direction, it can turn the meat products being crushed upwards, thereby improving the uniformity and effect of crushing the meat products and reducing meat loss during the processing.

[0024] (3) By setting the crushing blade 1 in the crushing component 1 to be able to move within a certain range of the axial direction of the rotating shaft, it can better assist the multiple crushing blades 3 in the crushing component 2 to carry out the rapid crushing operation of meat products.

[0025] (4) The setting of the limiting component, the discharge cylinder and the discharge pipe makes it easy to adjust and limit the discharge direction according to the discharge needs, which greatly improves the flexibility of operation and adapts to different production needs.

[0026] (5) The opening and closing control component facilitates the control of the opening and closing operation between the top cover and the meat grinder casing, thereby facilitating equipment maintenance and parts replacement, simplifying the maintenance process, and reducing maintenance costs.

[0027] In summary, the meat grinding equipment and its method for processing meat products of the present invention not only improves the efficiency of meat grinding and the uniformity of meat product crushing, but also significantly reduces the difficulty of operation and maintenance costs through innovative design. Furthermore, it reduces meat residue in the equipment and minimizes meat loss during processing. In addition, the flexible discharge adjustment function allows the meat grinding equipment to meet the needs of different production scales, benefiting both small family workshops and large food processing plants. Overall, the meat grinding equipment of the present invention provides an efficient, economical, and convenient solution for the meat processing industry. Attached Figure Description

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 limitations on this invention.

[0040] Reference Figure 1-9A meat grinder for processing meat products includes a grinder housing 1, a top cover 2, a rotating shaft 4, a support ring 42, and multiple crushing blades 41. The top of the grinder housing 1 is open, and the top cover 2 is snapped onto the top of the grinder housing 1 and is adapted to the top opening of the grinder housing 1. Two ear plates 23 are symmetrically fixedly installed on the outer side of the top cover 2. Multiple fixing blocks are fixedly installed on the outer side of the grinder housing 1. The same electric cylinder 22 is fixedly installed on the multiple fixing blocks on the same side. The working ends of the two electric cylinders 22 are respectively fixedly connected to the corresponding ear plates 23, which can control the opening and closing operation between the top cover 2 and the grinder housing 1 as needed, thereby facilitating maintenance and component replacement.

[0041] A feed cylinder 21 is fixedly installed on the top cover 2. A discharge cylinder 3 is sealed and rotatably installed at the bottom center of the meat grinder housing 1. A discharge pipe 31 connected to the discharge cylinder 3 is fixedly installed on the bottom outer side of the discharge cylinder 3. A rotating shaft 4 is rotatably installed in the center of the meat grinder housing 1. Multiple crushing blades 41 are fixedly installed on the rotating shaft 4 and arranged radially. A support ring 42 is rotatably installed on the top side of the top cover 2, and multiple crushing blades 41 are fixedly connected to the support ring 42. Multiple annular grooves are opened on the outer side of the rotating shaft 4. Sliding sleeves 401 are slidably installed in the multiple annular grooves along the axial direction of the rotating shaft 4. Multiple crushing blades 402 are fixedly installed radially on the outer side of the sliding sleeves 401. When the rotating shaft 4 rotates, the multiple crushing blades 402 can be controlled to rotate based on the rotating shaft 4 as the center, while allowing them to move up and down within the range of the annular grooves.

[0042] An annular groove is provided on the top side of the support ring 42. Multiple rotating rods 5 parallel to the rotating shaft 4 are rotatably mounted on the support ring 42. Multiple crushing blades 501 are radially fixedly mounted on each of the multiple rotating rods 5. The multiple crushing blades 501 are staggered with the corresponding crushing blades 402, which can cooperate with the crushing blades 402 to perform efficient crushing of meat products when the rotating rods 5 rotate rapidly. A toothed disc 52 is fixedly mounted on the bottom side of the top cover 2 at the position corresponding to the annular groove, with the rotating shaft 4 as the center. The top ends of the multiple rotating rods 5 extend into the annular groove and are respectively fixedly fitted with transmission gears 51. The multiple transmission gears 51 mesh with the toothed disc 52, which can control the rotating rods 5 to rotate rapidly when the rotating shaft 4 drives the support ring 42 to rotate through the crushing blades 41. This allows the multiple transmission gears 51 to cooperate with the toothed disc 52 to control the rotating rods 5 to rotate rapidly, thereby controlling the multiple crushing blades 501 to rotate rapidly with the corresponding rotating rods 5 as the center.

[0043] A support block 61 is fixedly installed radially on the outer side of the support ring 42. A scraper 6 is fixedly installed on the support block 61. A scraper 62 is fixedly installed at the bottom end of the scraper 6. The scraper 62 and the rotating shaft 4 are fixedly connected by the same connecting rod 63. Both the scraper 6 and the scraper 6 are in contact with the inner wall of the meat grinder housing 1. The scraper 6 is spirally arranged, which can control the scraper 6 and the scraper 62 to clean the inner wall of the meat grinder housing 1 when the support ring 42 rotates. At the same time, since the scraper 6 is spirally arranged, when the support ring 42 drives the scraper 6 to move along the inner wall of the meat grinder housing 1, it can scrape the meat products adhering to the inner wall of the meat grinder housing 1 upward or downward, so that the meat products can be turned over when scraping upward, thereby further improving the crushing effect of the meat products.

[0044] The bottom of the discharge cylinder 3 is enclosed. A motor 72 is fixedly installed at the bottom of the discharge cylinder 3. The output shaft of the motor 72 extends into the discharge cylinder 3 and is axially fixedly connected to a spindle 7. A spiral blade 71 is fixedly installed on the spindle 7. The top ends of the spindle 7 and the spiral blade 71 extend into the meat grinder housing 1. The top end of the spindle 7 is detachably connected to the bottom end of the rotating shaft 4. The spiral blade 71 is consistent with the spiral direction of the scraper 6. When it is necessary to discharge, the crushed meat products can be discharged through the discharge pipe 31. At the same time, when rotating in the reverse direction, the meat products at the position of the discharge cylinder 3 can be flipped upward. In addition, it can also provide driving force for the rotating shaft 4.

[0045] The bottom of the meat grinder casing 1 is provided with multiple limiting grooves 33 centered on the discharge cylinder 3. An installation block 321 is fixedly installed on the outside of the discharge cylinder 3. A rotating pin 322 is rotatably installed on the installation block 321. A T-shaped limiting rod 32 is radially fixedly installed on the rotating pin 322. A torsion spring 323 is fixedly installed on the limiting rod 32 centered on the rotating pin 322. The end of the torsion spring 323 away from the limiting rod 32 is fixedly connected to the installation block 321, and the limiting rod 32 is engaged in the corresponding limiting groove 33. This allows for manual control of the discharge cylinder 3 to rotate, thereby adjusting the discharge direction as needed. It also allows for limiting the discharge direction after adjustment, preventing the discharge direction from deviating on its own during the discharge process.

[0046] In this embodiment, the bottom end of the rotating shaft 4 is provided with multiple slots, and the top end of the spindle 7 is fixedly installed with a snap-fit ​​block 73. The snap-fit ​​block 73 is snap-fitted into the slots, and the vertical projections of the slots and the snap-fit ​​block 73 are both set in a regular polygon shape, which can ensure the transmission of power between the spindle 7 and the rotating shaft 4, and at the same time facilitate quick assembly and disassembly.

[0047] In this embodiment, it is worth noting that, for ease of understanding, the forward rotation of the motor 72 described above should be understood as driving the spiral blades 71 to convey the processed meat products inside the meat grinder housing 1 downwards, i.e., the discharge state, while the reverse rotation of the motor 72 means controlling the spiral blades 71 to convey the meat products in the discharge cylinder 3 into the meat grinder housing 1.

[0048] In order to ensure the accuracy of the top cover 2 when it is closed with the meat grinder housing 1, a circular groove is provided on the bottom side of the top cover 2, and the top outer side of the meat grinder housing 1 is stepped. The top cover 2 is sealed and snapped into the stepped position on the top outer side of the meat grinder housing 1 through the circular groove.

[0049] In addition, to prevent contamination of meat products by component materials, all components that come into contact with meat products during the meat grinding process are made of 304 stainless steel, which meets food hygiene and safety standards. Examples include: the meat grinder housing 1, crushing blade 1 402, crushing blade 2 41, crushing blade 3 501, rotating rod 5, rotating shaft 4, spindle 7, scraper 1 6, scraper 2 62, feed cylinder 21, and discharge cylinder 3. This material has excellent corrosion resistance and high-temperature resistance, enabling it to withstand acidic or alkaline substances encountered during meat grinding and also to withstand high-temperature sterilization. Furthermore, all surfaces in contact with meat products are finely polished to ensure no sharp edges or burrs, preventing any physical damage to the meat products. This design not only ensures food safety but also improves the service life and working efficiency of the meat grinder.

[0050] Working principle: First, connect the power supply and start the motor 72. The motor 72 drives the spindle 7 to rotate in the opposite direction. With the cooperation of the locking block 73 and the slot, it can drive the rotating shaft 4 to rotate synchronously. The rotating shaft 4 controls the support ring 42 to rotate through multiple crushing blades 41, so that multiple rotating rods 5 rotate around the rotating shaft 4. At the same time, with the cooperation of the gear plate 52 and the transmission gear 51, multiple rotating rods 5 can maintain a state of rapid self-rotation. Thus, the rotating shaft 4 and the rotating rods 5 can maintain a state of opposite rotation and control the corresponding crushing blades 402 and 501 to rotate. While the support ring 42 rotates, the support block 61 drives the spirally arranged scraper 6 and scraper 62 to move along the inner wall of the meat grinder casing 1 and achieve the cleaning function.

[0051] The meat products to be processed are fed into the meat grinder housing 1 through the feed cylinder 21, or after being placed in the feed cylinder 21, a downward force is applied to its top. As the meat products pass through multiple crushing blades 41, they are sliced ​​by the action of these blades and fall into the working range of crushing blades 402 and 501. Because the rotational speed of crushing blade 501 is greater than that of crushing blade 402 and they rotate in the opposite direction, the meat products entering the meat grinder housing 1 can be quickly and efficiently crushed. Inevitably, during this process... When meat scraps are thrown onto the inner wall of the meat grinder housing 1, the spirally arranged scraper 6 and scraper 62 can clean them. The spirally arranged scraper 6 will scrape them upwards, so that they can be crushed again by the crushing blade 501. Since the crushing blade 402 is axially slidably installed in the annular groove on the rotating shaft 4 through the sliding sleeve 401, the crushing blade 402 will move up and down within the annular groove under the influence of the meat product during the crushing process, thereby further improving the uniformity of crushing.

[0052] When the meat product is finished processing and needs to be discharged, manually control the T-shaped limiting rod 32 to disengage it from the limiting groove 33. Then rotate the discharge cylinder 3 and adjust the discharge pipe 31 to the desired discharge direction. Release the limiting rod 32, and under the action of the torsion spring 323, it can be locked into the corresponding limiting groove 33, thus preventing the discharge direction from deviating on its own during the discharge process. Then control the motor 72 to rotate forward, thereby controlling the spiral blades 71 to remove the material accumulated on the meat grinder casing. Meat at the bottom inner wall is conveyed and discharged from the discharge pipe 31 through the discharge cylinder 3. Since the spiral blade 71 and the scraper 6 are in the same spiral direction, the scraper 6 scrapes the meat adhering to the inner wall of the meat grinder housing 1 downwards, and the scraper 62 assists in sending it to the feeding position of the discharge cylinder 3. As the discharge continues, the amount of meat products in the meat grinder housing 1 decreases, so that most of the meat scraps on the crushing blade 402 and the crushing blade 501 will be thrown out under the action of centrifugal force.

[0053] When it is necessary to inspect or replace the parts inside the meat grinder housing 1, the ear plate 23 is controlled by the electric cylinder 22 to drive the top cover 2 to move upward, so that the slot on the rotating shaft 4 can be disengaged from the locking block 73 at the top of the spindle 7. At the same time, the rotating rod 5, support ring 42, crushing blade 1 402, crushing blade 2 41 and crushing blade 3 501, as well as scraper 1 6 and scraper 2 62, will all move upward with the top cover 2, so as to facilitate the technicians to carry out inspection or replacement of parts.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
