Description

Technical Field

[0001] This invention belongs to the field of automated production equipment and process technology for pre-made food, and in particular relates to a pre-made pig's feet ginger roll and its automatic forming equipment. Background Technology

[0002] Pig's feet with ginger is a traditional Chinese delicacy, especially popular in southern my country, and is believed to have warming and nourishing properties. However, the traditional preparation process is complex and time-consuming, involving multiple steps such as stewing the pig's feet, deboning, and soaking them in ginger and vinegar sauce. It heavily relies on the chef's experience, resulting in inconsistent quality, low production efficiency, and difficulty in large-scale production.

[0003] With the rapid development of the pre-prepared food market, the demand for standardized, industrially produced pig's feet and ginger products is increasing. Several existing technologies attempt to industrialize the production of pig's feet and ginger. For example, Chinese patent application CN106578988A discloses a method for preparing pig's feet and ginger using pig's feet and ginger as raw materials, and aged vinegar and rock sugar as auxiliary ingredients. The process involves cutting, air-drying, salt-roasting, hot braising, inner packaging, sterilization, and outer packaging. Efficiency is improved through vacuum tumbling and braising processes. However, these existing technologies still have many shortcomings in practical applications. 1. The above-mentioned products are traditional "soup-style" products. The pig's feet are in chunks and separated from the soup. The soup needs to be carried separately in soup packaging, which is costly, heavy, and inefficient in transportation, and there is a risk of leakage. They often need to be heated before consumption and require additional utensils. They are not convenient as snacks or ready-to-eat products. The experience is not fundamentally different from traditional home-made products, which limits the consumption scenarios. Currently, some products soak the pig's feet in ginger and vinegar sauce. This method makes the pig's feet chunks loose, and the pig's feet meat is easy to break apart and become soft and mushy, resulting in poor taste. It is impossible to form a regular and beautiful product shape. The consumer experience is far from that of traditionally made products. The flavor of existing products depends on the pig's feet chunks soaking in the soup to absorb the flavor. It is difficult to accurately control the evenness and concentration of the flavor, which may result in inconsistent flavor strength. 2. The existing production equipment has a low degree of automation integration, especially in the two key steps of shaping and demolding and uniform coating. It still relies heavily on manual operation or semi-automatic equipment. This not only leads to low production efficiency and high labor costs, but also makes it difficult to ensure the stability and consistency of product quality. In addition, excessive human involvement in the production process increases the risk of food contamination. At the same time, during demolding and transfer, products are easily damaged and their shape is incomplete, resulting in a decrease in yield and waste of raw materials. 3. Existing technologies are difficult to achieve precise and controllable automated coating, often resulting in problems such as uneven coating thickness, wasted sauce, or incomplete coating.

[0004] To address these issues, we provide a pre-made pig's feet ginger roll and its automatic forming equipment. Summary of the Invention

[0016] The present invention has the following beneficial effects: 1. The pre-made pig's feet ginger roll provided by this invention reorganizes and shapes minced pig's feet meat into a solidified cylindrical meat roll core, and then wraps it with ginger juice paste, forming a new "roll" shape with a tight structure and good elasticity. This shape is beautiful and neat, forming a solid, integrated snack product that is convenient to eat, has a chewy texture, and has an innovative product shape and better taste. It perfectly solves the problems of loose and easily falling apart traditional pre-made pig's feet ginger rolls, as well as the problems of inconvenience in carrying and limited consumption scenarios of traditional shapes, and provides a richer and more convenient consumer experience.

[0017] 2. This invention integrates automatic shaping, precise material picking, rotary immersion, centrifugal material throwing, and automated unloading. Through a unique "row-by-row material picking - mold resetting and refilling - station switching" circulating production line design, it achieves seamless automation of the entire process from raw materials to finished products, achieving a high degree of automation and large-scale production. This greatly improves production efficiency, significantly reduces labor costs and food safety risks caused by human intervention, and lays a solid foundation for large-scale mass production. In addition, the provided automatic forming equipment reshapes and solidifies the minced meat, fundamentally ensuring that the size, shape, and density of each meat roll core are completely consistent, solving the quality fluctuation problem caused by the differences in raw materials in traditional block products, and achieving a high degree of product standardization.

[0018] 3. The automatic forming equipment provided by the present invention ensures that the thickness of the ginger paste wrapped around each product is thin and uniform through the centrifugal spinning process after soaking, thus guaranteeing the consistency of product flavor, appearance and weight. At the same time, it reduces the waste of sauce and solves the problems of uneven flavoring, uncontrollable flavor and excessive soup residue caused by the soaking method.

[0019] 4. The automatic forming equipment provided by the present invention has a material picking mechanism that directly inserts the meat roll core through the insert rod, and combined with the synchronous ejection action of the push-up component, it achieves efficient and damage-free demolding, effectively avoids damage, breakage or incomplete shape of the product during demolding and transfer, and significantly improves the yield.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] This embodiment represents the core cycle of the equipment, encompassing a complete and continuous automated process from mold preparation and single-row material handling to mold resetting, refilling, and switching to the next row. The specific operations are as follows: Step 1, raw material preparation and mold installation, as detailed below; First, the pre-treated minced pork trotters are thoroughly mixed with gelatin powder as a binder to form a slurry with a certain degree of fluidity. Then, the shaping mold 420 containing this slurry is installed onto the drive frame 410. The specific installation operation is as follows: By controlling the retraction of the hydraulic rods 412 on both sides, the mold base 413 is driven to slide outward along the rail base 411, leaving sufficient installation space; Then, the bottom plate of the shaping mold 420 is precisely placed into the upper rectangular through groove of the seat groove 4131. Then, the limiting cylinders 4141 of the two limiting components 414 are activated to push the limiting plate 4142 to move inward, pressing the bottom plate of the shaping mold 420 tightly from both sides, thus completing its precise positioning and fixation. Finally, the hydraulic rod 412 extends, pushing the mold base 413 and the shaping mold 420 on it to move inward to the working position. At this time, the first row of mold slots on the mold and the row of push rods 433 of the push assembly 430 are aligned vertically. Step two, initial injection and shaping, are detailed below: First, thoroughly mix the processed minced pork trotters with gelatin powder to form a slurry with a certain degree of fluidity. Then, through an external injection machine (not shown in the diagram, but which is a conventional device in this field and will not be described in detail here), the slurry is automatically and precisely injected into each mold slot of the shaping mold 420 inside the shaping box 400, so that each mold slot is filled with slurry. After injection, the setting box 400 is started by temperature control switch to lower the temperature inside the setting box 400 to below the gelatin's curing point, so that the slurry is set at low temperature and solidified into a columnar meat roll core. Step 3, unloading and demolding the first row of materials, as detailed below: First, the material handling mechanism 300 is initially positioned. Specific operation steps: The servo motor of the lead screw structure 220 starts first, driving the lead screw to rotate, which in turn moves the entire first drive seat 210 longitudinally (Z-axis) along the frame 200 and rises to a safe height. Then, the first motor of the first lead screw assembly 212 starts, driving the first lead screw to rotate, which in turn moves the first slide 213 laterally (Y-axis), so that the entire material handling mechanism 300 moves precisely above the shaping box 400, ensuring that the row of insert rods 323 on the insert structure 320 is precisely aligned with the first row of mold slots in the shaping mold 420. Then, the feeding mechanism 300, in conjunction with the upward pushing component 430, pushes out the meat roll core. Specific operation: The lead screw structure 220 drives the first drive seat 210 to descend, causing the insertion rod 323 to move vertically downward and insert into the center of the first row of meat roll cores, completing the insertion action. Subsequently, the electric push rod 431 of the push assembly 430 and the servo motor of the lead screw structure 220 receive signals and start synchronously. At this time, the electric push rod 431 drives the pusher seat 432 to rise, causing the push rods 433 on the pusher seat 432 facing the first row to move upward synchronously, pushing against the circular pads at the bottom of the mold slots of the first row. At the same time, the lead screw structure 220 drives the first drive seat 210 to rise synchronously at the same speed as the push rods 433, driving the insertion rods 323 that have been inserted into the meat roll cores. Vertically upward, under the combined action of the gripping force of the insert rod 323 and the ejection force of the push rod 433, the first row of meat roll cores is completely detached from the mold slot (during the entire demolding stroke, since there is no relative displacement between the insert rod 323 and the push rod 433, i.e., they remain relatively stationary, they move upward together as a whole. The gripping force of the insert rod 323 prevents the meat roll cores from tilting, while the ejection force of the push rod 433 acts evenly on the bottom of the meat roll cores. The combined force of the two smoothly and completely detaches the first row of meat roll cores from the mold slot). Afterwards, the screw structure 220 continues to drive the picking mechanism 300 to rise to the preset height, completing the extraction of the first row of meat roll cores. Step four, the key to mold reset, re-injection, and station switching cycles. After the feeding mechanism 300 leaves with the first row of meat roll cores, the shaping station 110 immediately and automatically performs the following operations to prepare for the next feeding: Mold reset (moved to injection station): The two hydraulic rods 412 on the drive frame 410 retract simultaneously, pulling the mold base 413 and the entire shaping mold 420 carried on it to slide outward (towards the equipment operating surface) along the rail base 411 until the first row of mold slots that were just emptied moves and stops below the original injection machine (this position can be regarded as the "injection station"). Refilling: The external filling machine is not shown to start immediately in the diagram. It refills the mixture of minced pork and gelatin into the first row of empty mold slots. Switching to the second row of mold slots and moving to the material picking area: After the material is injected, the hydraulic rods 412 on both sides extend and push the mold base 413 and the shaping mold 420 towards the frame 200 until the second row of mold slots is moved to the position of the first row of mold slots for material picking (this position can be regarded as the "material picking area"). This movement allows the meat roll core that has been shaped in the second row of mold slots to be precisely moved from its previous position to the position where the first row of meat roll cores was picked up, waiting to be picked up again. After each shaping station 110 completes a work cycle, the material picking mechanism 300 will complete the entire process and return. After returning to the picking area, the material picking mechanism 300 will repeat the material picking process in step one, and pick up the second row of meat roll cores that are already in the picking area. After the second row is picked up, the hydraulic rod 412 will push the mold outward again, so that the empty mold slots of the second row will be moved to the injection station for refilling. After filling, it will move inward again, so that the third row of mold slots will be in place in the picking area. This cycle is repeated to realize the parallel assembly line operation of material picking, filling and moving. It should be added that the cycle starts as follows: the shaping mold 420 has been installed and all its mold slots have been filled with slurry and cooled to form multiple rows of meat roll cores. Example 2

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on Example 1, an immersion tank 500 is fixed at the immersion station 120. The immersion tank 500 is an intelligent constant temperature box to ensure that the ginger juice paste maintains a paste with suitable viscosity and temperature. A temperature control switch is fixed on the outer periphery of the immersion tank 500. The transmission assembly 322 includes a shaft 3221, a gear 3222, and a sleeve 3224. The gear 3222 is fixed to the outside of the shaft 3221. The gears 3222 of two adjacent transmission assemblies 322 mesh with each other. A connecting part 3223 is installed on the bottom side of the shaft 3221. The sleeve 3224 is fixed to the bottom of the shaft 3221. The top surface of the mounting base 321 has a set of circular grooves, which are connected to each other. A through hole is provided in the center of each groove. The connecting part 3223 of the transmission component 322 is movably installed in the through hole of the corresponding circular groove of the mounting base 321.

[0039] Specifically, the inner wall of the insert 3224 has a ring of hemispherical grooves, and the top of the insert 323 is fixed with a ring of evenly distributed hemispherical protrusions. The hemispherical grooves and hemispherical protrusions are arranged in a one-to-one correspondence, and the size of the hemispherical protrusions matches the size of the hemispherical grooves.

[0040] In this embodiment, after the material handling mechanism 300 extracts a row of meat roll cores, it performs soaking and surface treatment. The specific operation is as follows: Step 1, soaking treatment, as detailed below; The material handling mechanism 300 carries the first row of meat roll cores and moves horizontally above the immersion station 120 through the drive of the first screw assembly 212, aligning the row of products with the center of the immersion tank 500. Then the servo motor of the lead screw structure 220 starts, drives the lead screw to rotate, and drives the entire first drive seat 210 to move down along the frame 200, causing the first row of meat roll cores carried by the material picking mechanism 300 to move vertically down and insert into the ginger paste in the soaking tank 500. After soaking in the juice, the servo motor of the lead screw structure 220 starts again, driving the entire first drive seat 210 to move upward along the frame 200, causing the first row of meat roll cores carried by the feeding mechanism 300 to be completely removed from the top surface of the ginger paste in the soaking tank 500. Then, the servo motor of the lead screw structure 220 starts again, driving the entire first drive seat 210 to move downward along the frame 200, causing the first row of meat roll cores carried by the feeding mechanism 300 to move vertically downward again and insert into the ginger paste in the soaking tank 500. This process is repeated several times to ensure thorough soaking in the juice. After the soaking process is complete, the servo motor of the lead screw structure 220 is started, which continues to move the entire first drive seat 210 upward along the frame 200 to the preset height. Then, the cylinder 3122 in the third drive seat 312 pushes the toothed plate 3123 downward. At this time, the downward moving toothed plate 3123 will mesh with the toothed shaft 3133 on the fourth drive seat 313, converting linear motion into rotational motion. This action will drive the entire fourth drive seat 313 and the insertion structure 320 to rotate 90° around the axis of the toothed shaft 3133, causing the insertion structure 320 to change from a vertical state to a horizontal state. At this time, the soaked meat roll core is placed horizontally. Then, the drive motor 3134 is started, driving the shaft 3 of a transmission component 322. 221 rotates, and its gear 3222 meshes with the adjacent gear 3222, transmitting power to all transmission components 322 in the row, thereby driving all the insert rods 323 and the meat roll core to rotate slowly together. During the rotation process, excess ginger paste on the surface of the meat roll can be shaken off. After a preset time, the ginger paste quickly solidifies on the surface of the meat roll core, forming a finished pig's foot ginger roll with a thin and uniform solid coating. At this point, the soaking process of the first row of products is completed (during this period, the shaping station 110 is simultaneously completing the filling of the first row of empty mold slots and the positioning of the second row of mold slots). Example 3

[0041] Please see Figure 1 , Figure 2 , Figure 9 and Figure 10 Based on Embodiments 1 and 2, an unloading mechanism 600 is installed at the unloading station 130. The unloading mechanism 600 includes a moving component 610 and an unloading box 620. The unloading box 620 is slidably connected to the moving component 610, and the inner bottom of the unloading box 620 has a sloping structure.

[0042] Specifically, the moving assembly 610 includes a base frame 611, a hydraulic push rod 612, and a moving plate 613. The base frame 611 includes a seat plate 6111 and a rail rod 6112. Two seat plates 6111 are fixed to the top surface of the processing table 100. Symmetrically arranged rail rods 6112 are fixed between the two seat plates 6111. The rail rods 6112 pass through both sides of the moving plate 613. Both sides of the moving plate 613 are movably connected to the rail rods 6112 on both sides. A hydraulic push rod is fixed to the inner side of one of the seat plates 6111. 612, the output end of the hydraulic push rod 612 is connected to the side of the moving plate 613. The hydraulic push rod 612 drives the moving plate 613 to move on the rail rod 6112. The bottom of the unloading box 620 is fixed on the moving plate 613. A row of evenly distributed unloading grooves 621 is opened on the side of the unloading box 620. A row of unloading grooves 621 is set in correspondence with a row of insert rods 323. The size of the unloading groove 621 is larger than the size of the insert rod 323 (so that the horizontal insert rod 323 can be moved down and inserted into the unloading groove 621).

[0043] This embodiment demonstrates an automated unloading process for pig's feet and ginger rolls. The specific operation process is as follows: Step 1, transfer to unloading station 130: The material handling mechanism 300 carries the first row of finished pig's feet ginger rolls in a horizontal position and moves them above the unloading station 130, ensuring that the front end of each insertion rod 323, i.e. the part of the insertion rod 323 that is not inserted into the pig's feet ginger roll, is aligned with a row of unloading slots 621. Then the servo motor of the screw structure 220 is started again, driving the first row of finished pig's feet ginger rolls to move down, so that the front end of the insertion rod 323 is horizontally inserted into the corresponding unloading slot 621. Then, the hydraulic push rod 612 of the moving component 610 is activated, pushing the moving plate 613 and the unloading box 620 on it to move smoothly outward away from the material picking mechanism 300 along the rail 6112. Since the diameter of the unloading groove 621 is larger than the diameter of the insert rod 323 but smaller than the diameter of the pig's feet ginger roll, when the unloading box 620 moves outward, the edge of the groove will block and scrape the finished pig's feet ginger roll, so that the insert rod 323 can be smoothly removed from the product transferred to the unloading station 130. After the whole row of finished pig's feet ginger rolls are completely removed from the insert rod 323, they will fall into the unloading box 620 and slide along the inclined surface to the conveyor belt or collection basket below to complete the unloading operation. After unloading is completed, the hydraulic push rod 612 retracts, pulling the unloading box 620 to reset, and the material picking mechanism 300 rises again, ready to return to the shaping station 110 to pick up the second row of meat roll cores that have been placed, and start the next complete product cycle.
