Description

Technical Field

[0001] This utility model relates to the field of chilled meat processing technology, specifically to an integrated device for chilled meat conveying and packaging. Background Technology

[0002] With the development of modern food processing industry, chilled fresh meat has gradually become the mainstream product in the fresh meat consumption market due to its better taste, higher nutritional value and safety and hygiene characteristics. In the modern automated processing and production of chilled fresh meat, the cut meat slices usually need to go through multiple processes such as conveying, sorting, weighing, boxing and subsequent packaging.

[0003] However, in the current processing and transportation of chilled fresh meat, the boxing operation is generally completed manually or semi-automatically, which results in high labor intensity and low production efficiency. At the same time, there is a lack of effective control over the material drop path, which makes it easy for meat slices to stack, shift or even splash when falling into the packaging container, affecting the neatness of filling and the accuracy of weighing. Based on this, we propose an integrated chilled fresh meat conveying and packaging device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated device for conveying and packaging chilled meat, which facilitates the stable conveying of cut meat products. It solves the problem that in the current process of processing and conveying chilled meat, the boxing operation is generally completed manually or semi-automatically, resulting in high labor intensity and low production efficiency. At the same time, the lack of effective control over the material drop path causes meat slices to easily stack, shift, or even splash when falling into the packaging container, affecting the neatness of the filling and the accuracy of weighing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated device for conveying and packaging chilled meat, comprising a conveyor frame connected to the discharge end of a cutting device and a pusher frame connected to the discharge end of the conveyor frame. The conveyor frame is internally equipped with a conveyor belt for conveying cut meat slices. A movable fixture that can reciprocate horizontally is slidably mounted on the upper end of the pusher frame. A packaging box for holding the meat is provided on the top of the movable fixture. A guide plate is provided at the discharge end of the conveyor frame. An angle adjustment component is provided between the lower end of the guide plate and the conveyor frame. The angle adjustment component is used to adjust the tilt angle of the guide plate relative to the conveyor frame to control the direction and speed of the meat slices falling. A weighing unit is provided at the bottom inner side of the movable fixture. The weighing unit is used to weigh the net weight of the meat falling into the packaging box in real time, and the weighing unit transmits the weight signal to the control system.

[0006] Furthermore, the angle adjustment assembly includes a hinge seat fixedly installed at the bottom of the guide plate and a telescopic cylinder rotatably installed at the bottom of the conveyor frame. The output end of the telescopic cylinder is rotatably connected to the lower end of the guide plate, and the guide plate is rotatably installed on the inner side of the conveyor frame through the hinge seat. The telescopic cylinder is used to drive the guide plate to rotate around its upper hinge point to adjust the tilt angle.

[0007] Furthermore, the surface of the deflector is coated with a food-grade non-stick coating, and splash guards are fixedly installed on both sides of the deflector.

[0008] Furthermore, the moving fixture is slidably mounted on the pusher frame via a roller structure, and is driven by a pneumatic push rod to perform periodic feeding movements.

[0009] Furthermore, the weighing unit is a high-precision strain gauge load cell.

[0010] Furthermore, the conveyor belt is made of polyurethane material with shallow grooves or textures, and there is a gap between the end of the conveyor belt and the guide plate, so that the meat slices slide into the packaging box one by one.

[0011] Furthermore, the control system includes a central controller, which receives weight data from the weighing unit and, when the meat in the packaging box reaches the preset target weight, drives the guide plate to flip upward.

[0012] Furthermore, the entire machine operates in a low-temperature clean environment of 0-4℃, and all parts that come into contact with meat are made of SUS304 stainless steel or food-grade engineering plastics.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This integrated cold meat conveying and packaging device uses a conveyor belt to carry the meat out of the machine, which facilitates the transport of meat slices to the outside of the cutting device and allows the meat to be fed into the packaging box through the guide plate. At the same time, a weighing unit is used to weigh the meat in real time to meet the quantitative packaging standards. The moving tooling feeds periodically and is arranged in parallel with multiple boxes to realize the integrated operation of conveying and packaging.

[0015] 2. This integrated cold-frozen meat conveying and packaging device dynamically adjusts the tilt angle of the guide plate through the angle adjustment component to adapt to the sliding characteristics of meat slices of different thicknesses and moisture levels, ensuring smooth and orderly material delivery and avoiding impact and accumulation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In modern automated chilled meat processing lines, after the cutting process, the meat slices must go through multiple intermediate stages such as conveying, sorting, weighing, and boxing before entering the final processing stages such as vacuum packaging, labeling, and finished product warehousing. Among these, boxing, as a key transitional process connecting the front-end cutting and the back-end packaging, directly affects the overall production efficiency, product appearance quality, and food safety control level.

[0024] However, most meat processing enterprises still rely on manual picking or semi-automatic assisted methods for boxing. This not only depends on a large number of operators working repetitively for long periods in low-temperature environments, resulting in high labor costs and high labor intensity, but also, due to the inherent randomness of manual operation, easily leads to problems such as uneven boxing, inconsistent quantities, and large weight deviations, making it difficult to meet the quality control requirements of standardized and large-scale production. More importantly, in the extremely demanding 0-4℃ cold chain processing environment, frequent manual contact with meat products can easily introduce exogenous microbial contamination, significantly increasing the risk of cross-transmission of pathogenic bacteria such as Salmonella and Listeria, seriously threatening food safety and consumer health.

[0025] Although some equipment manufacturers have attempted to develop mechanical devices with basic conveying or guiding functions to replace manual labor in recent years, existing technologies generally have many limitations: On the one hand, the material drop channels are mostly fixed structures, lacking the ability to dynamically adjust the guide angle, and cannot adapt to the sliding characteristics of meat slices of different thicknesses, moisture contents, or viscosity. This often leads to excessively fast sliding speed and impact force of the meat slices, resulting in stacking, flipping, offsetting, or even splashing, affecting the neatness of the box and the accuracy of subsequent weighing; on the other hand, most systems do not integrate online dynamic weighing modules, cannot obtain the cumulative weight information in the packaging container in real time, and lack a closed-loop feedback control mechanism. Therefore, they cannot achieve the intelligent filling mode of "quantitative filling on demand and precise stopping of material", and still need to rely on manual re-weighing, replenishment, or rejection of out-of-tolerance products, further reducing the degree of automation of the production line and the consistency of the operating cycle.

[0026] In addition, existing equipment often isolates functions such as conveying, weighing, and filling, resulting in poor connection between units and a lack of system-level collaborative control strategies. This leads to low overall integration, poor space utilization, and high failure rate, making it difficult to form a continuous production line with efficient linkage with upstream cutting machines and downstream vacuum packaging machines. For example, a meat roll cutting and packaging integrated machine with publication number CN208325735U mainly adds a cooling structure to prevent meat from spoiling.

[0027] In summary, existing technologies still have significant shortcomings in areas such as controllability of material feeding, real-time weighing, system integration, and food safety assurance capabilities. There is an urgent need to develop an integrated chilled meat conveying and packaging device that combines intelligent flow guidance, dynamic weighing, closed-loop control, and clean operation to overcome traditional process bottlenecks and promote the transformation and upgrading of the meat processing industry towards high efficiency, intelligence, and green practices. Figures 1-5 This embodiment of a chilled meat conveying and packaging integrated device includes a conveyor frame 1 connected to the discharge end of the cutting device and a pusher frame 2 connected to the discharge end of the conveyor frame 1. The conveyor frame 1 is equipped with a conveyor belt 3 for conveying the cut meat slices. The upper end of the pusher frame 2 is slidably equipped with a moving fixture 4 that can reciprocate in the horizontal direction. The top of the moving fixture 4 is equipped with a packaging box 5 for holding the meat. The discharge end of the conveyor frame 1 is equipped with a guide plate 6. The lower end of the guide plate 6 is provided with an angle adjustment component between it and the conveyor frame 1. The angle adjustment component is used to adjust the tilt angle of the guide plate 6 relative to the conveyor frame 1 to control the direction and speed of the meat slices falling. The bottom of the inner side of the moving fixture 4 is equipped with a weighing unit. The weighing unit is a high-precision strain gauge weighing sensor. The weighing unit is used to weigh the net weight of the meat falling into the packaging box 5 in real time, and the weighing unit transmits the weight signal to the control system.

[0028] In this embodiment, the surface of the deflector plate 6 is covered with a food-grade non-stick coating, and anti-splash edges are fixedly installed on both sides of the deflector plate 6.

[0029] It should be noted that the food-grade non-stick coating is preferably made of polytetrafluoroethylene (PTFE) or modified polyethersulfone (PES), which has excellent low friction and anti-adhesion properties. It can effectively prevent wet and slippery meat slices from adhering to the surface of the guide plate during the slide, ensuring continuous and stable material delivery. The anti-splash guards on both sides are 30-50mm high and have a detachable structural design, which facilitates daily cleaning and maintenance, avoids bacterial growth, and meets the hygiene and safety requirements of the chilled meat processing process.

[0030] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, the movable tooling 4 is slidably mounted on the pusher frame 2 via a roller structure, and is driven by a pneumatic push rod to perform periodic feeding movements.

[0031] It should be noted that the roller structure includes four sets of symmetrically arranged guide rollers, which are embedded in the T-shaped guide rail groove at the top of the pusher frame 2 to achieve smooth sliding; the pneumatic push rod is fixed to the side wall of the pusher frame 2, and its piston rod is hinged to the tail of the moving fixture 4. Under the command of the central controller, it performs a "forward-stop-return" cycle action. After each quantitative filling is completed, the currently full packaging box 5 is automatically moved out of the loading area, and the next empty box is precisely positioned directly below the guide plate 6 to prepare to receive the next batch of meat slices, thereby realizing multi-station continuous operation.

[0032] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the angle adjustment component includes a hinge seat 7 fixedly installed at the bottom of the guide plate 6 and a telescopic cylinder 8 rotatably installed at the bottom of the conveyor frame 1. The output end of the telescopic cylinder 8 is rotatably connected to the lower end of the guide plate 6, and the guide plate 6 is rotatably installed on the inner side of the conveyor frame 1 through the hinge seat 7. The telescopic cylinder 8 is used to drive the guide plate 6 to rotate around its upper hinge point to adjust the tilt angle.

[0033] In this embodiment, the conveyor belt 3 is made of polyurethane material with shallow grooves or textures, and there is a gap between the end of the conveyor belt 3 and the guide plate 6, so that the meat slices slide into the packaging box 5 one by one.

[0034] It should be noted that the gap width is controlled between 10 and 20 mm, which can ensure that the meat slices can smoothly transition to the guide plate 6 without jamming, and can also avoid the impact and deviation caused by the meat slices falling freely due to excessive gap. The running speed of the conveyor belt 3 can be adjusted according to the production rhythm (usually 0.2 to 0.6 m / s), which, together with the front cutting frequency, ensures that only one piece of meat enters the dropping area at a time, realizing orderly feeding of single pieces and improving the neatness of boxing and the accuracy of weighing.

[0035] In this embodiment, the control system includes a central controller, which receives weight data from the weighing unit and, when the meat in the packaging box 5 reaches the preset target weight, drives the guide plate 6 to flip upward.

[0036] The working principle of the above embodiments is as follows:

[0037] Before the work begins, the system is powered on and started. The central controller initializes each execution unit. The moving fixture 4 moves to the initial loading position under the drive of the pneumatic push rod, so that the packaging box 5 is precisely aligned with the outlet of the guide plate 6. At this time, the guide plate 6 is in a preset tilt angle (such as 30° to 45°), supported and locked by the telescopic cylinder 8. After the cutting device continuously cuts the chilled fresh meat into slices of equal thickness, the slices fall onto the conveyor belt 3 in sequence. They are smoothly transported to the discharge end by the textured polyurethane belt surface. The slices slide out from the end of the conveyor belt 3, guided by the guide plate 6, and slide down its slope one by one into the packaging box 5 located below. Because the surface of the guide plate 6 is coated with a non-stick layer and has baffles on both sides, the meat slices slide smoothly without sticking or overflowing. As the meat slices fall in continuously, the high-precision strain gauge weighing sensor installed at the bottom of the moving fixture 4 continuously collects the total weight signal and uploads it to the central controller in real time. The controller makes dynamic judgments based on the preset target weight range (such as 300±10g, 500±15g, etc.). When the cumulative weight approaches the target value, the system enters the precision control stage. Once the set weight limit is reached, the central controller immediately issues a control command to drive the telescopic cylinder 8 to retract, pulling the lower end of the guide plate 6 upward, so that it quickly flips around the upper hinge point to a vertical or near-vertical state (i.e., the "closed" position), blocking the subsequent meat slices from falling into the current packaging box 5, achieving precise material stopping. Subsequently, the pneumatic pusher pushes the moving fixture 4 to move the full packaging box 5 to the next station, while sending the next empty packaging box 5 into the loading area. At the same time, the telescopic cylinder 8 extends again, resets the guide plate 6 to its original tilt angle, restores the material supply channel, and begins a new round of filling cycle.

[0038] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
