Description

Technical Field

[0001] This utility model relates to the field of ham sausage packaging technology, and in particular to a pneumatic ham sausage casing precision sealing machine. Background Technology

[0002] A sausage casing sealing machine is an automated or semi-automated device designed specifically for the sausage production process. Its main function is to seal casings filled with minced meat or other fillings. It seals the ends or specific sections of the casing through physical or chemical means, thereby achieving the shaping, leakage prevention, freshness locking, and extended shelf life of the sausage. Different types of sausage casing sealing machines have different main operating principles.

[0003] The pneumatic ham sausage casing precision sealing machine is a packaging machine that uses compressed air to precisely seal ham sausage casings. It employs a pneumatic drive system, using the movement of a cylinder to provide the necessary pressure for sealing. This ensures a tight seal on the casing, preventing meat filling leakage and guaranteeing the ham sausage is plump and full, resulting in good slicing quality. It is widely used in the production and processing of ham sausages and other meat products. However, in existing pneumatic ham sausage casing precision sealing machines, the contact pressure between the pressure head and the sealing mold relies on a single-point cylinder drive. After long-term use, deviations in the amount of meat filling wrapped in the casing can occur, leading to insufficient local pressure when the pressure head contacts the casing. This can cause bloating and spoilage during subsequent sterilization and storage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pneumatic ham sausage casing precision sealing machine, which aims to improve the existing technology where the amount of minced meat filling in the casing deviates after long-term use of the mold, which will lead to insufficient local pressure when the press head contacts the casing, and problems such as bag swelling and deterioration are likely to occur during subsequent sterilization and storage.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, before starting, the operator places the empty sausage casing on the discharge port of the filling machine on the right side of the workbench. After starting the system, the minced meat is quantitatively injected into the casing, forming an unsealed ham sausage embryo of uniform size, laying the foundation for subsequent sealing. After the sausage embryo enters the conveying mechanism, the motor on the right support frame drives the rotating shaft to rotate, driving the conveyor belt to transport the sausage embryo, ensuring that it is accurately aligned with the sealing component, and the fixing buckle fixes the sausage embryo. Simultaneously, the air compressor inside the positioning frame is started, and pressure is applied to the adjusting frame through the support rod, so that the clamping frame clamps the sausage casing sealing point. At the same time, the compressor pushes the pressing frame down, combined with the heating plate and mechanical pressing, to achieve a tight seal of the sausage casing, avoiding the problem of insufficient local pressure when the pressure head contacts the sausage casing, and preventing the bag from swelling and deterioration during subsequent sterilization and storage.

[0026] 2. In this utility model, after startup, the filling machine injects a measured amount of minced meat into the casing to form sausage embryos, which then enter the conveying mechanism. The protective shell of the conveying mechanism is fixed to the top of the support frame, serving as a protective component. Its top connecting tube supports the middle support tube and lifts the bottom of the sausage embryo, while also assisting in stabilizing the structure. The limiting tube on the inner side of the protective shell plays a major supporting and positioning role. After the motor on the right side of the inner wall starts, it drives the roller to rotate, using friction to drive the sausage embryo to move. At the same time, the positioning component on the outer wall of the limiting tube constrains the sausage embryo. The adjusting plate can adjust the spacing to adapt to different sausage embryos. The spring at the bottom of the right limiting tube provides elastic pressure, causing the limiting plate on the left side of the support tube to clamp the sausage embryo from both sides to prevent deviation, ensuring that the sausage embryo enters the conveyor belt of the conveying mechanism in a straight line.

[0036] Specifically, before starting the equipment, the ham sausage raw materials are filled by the filling machine 4. The operator puts the empty casing on the discharge port and starts the sausage filling system. The raw materials such as minced meat are quantitatively injected into the casing to form unsealed ham sausage embryos. The filling machine 4 ensures that each ham sausage embryo is of the same size, laying the foundation for subsequent sealing. The sausage embryos of different sizes are conveyed in a straight line to the conveyor belt 204 of the conveying mechanism 2. After the ham sausage embryos enter the conveying mechanism 2, the motor 203 drives the rotating shaft 206 to rotate, driving the conveyor belt 204 to circulate and convey the sausage embryos forward. The limit rod 205 constrains from the front and rear sides to prevent the sausage embryos from shifting laterally and ensures that they are aligned with the sealing component 207. When the sausage embryos are conveyed to the sealing component, Directly below 207, the sealing stage begins. Cylinder 2072 is activated, causing the positioning frame 2073 to slide down. The fixing buckle 2074 secures the sausage casing. Simultaneously, the air compressor 2075 is activated, applying pressure to the adjusting frame 2078. The clamping frame 2079 clamps the sausage casing. The air compressor 2075 pushes the pressing frame 2077 down, achieving sealing through heating or mechanical pressing. After a single sealing operation, the air compressor 2075 stops supplying air, the pressing frame 2077 resets, the positioning frame 2073 slides up, the fixing buckle 2074 opens from the clamping frame 2079, and the conveyor belt 204 delivers the sealed sausage. Unsealed sausage casings continue to enter, and the equipment operates in a cycle, achieving automated continuous sealing.

A limiting plate 3063 is rotatably connected to the left side of the outer wall of the support 3064.

[0038] Specifically, the filling machine 4 injects a measured amount of minced meat into the casing to form sausage embryos. The sausage embryos enter the conveying mechanism 3. The protective shell 301 of the conveying mechanism 3 is fixed to the top of the support frame 202 to protect the internal components. The connecting pipe 302 at the top of the protective shell 301 supports the support tube 3064 and helps stabilize the structure. The support tube 3064 is fixed in the middle of the connecting pipe 302 to support the bottom of the sausage embryo. The limiting tube 303 in the middle of the inner side of the protective shell 301 plays a supporting and positioning role. The motor 304 on the right side of its inner wall starts and drives the roller 305 to rotate, driving the sausage embryo to move by friction. At the same time, the positioning component 306 in the middle of the wall of the limiting tube 303 constrains the sausage embryo. The adjusting plate 3061 is fixed on the side of the limiting tube 303 and the spacing can be adjusted to adapt to different sizes of sausage embryos. The spring 3062 at the bottom of the right side of the limiting tube 303 provides pressure and drives the limiting plate 3063 to clamp the sausage embryo from both sides to prevent deviation and ensure that the sausage embryo enters the conveyor belt 204 of the conveying mechanism 2 in a straight line.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A cabinet door 5 is rotatably connected to the bottom front side of the workbench 1. A handle 6 is fixedly connected to the outer wall of the cabinet door 5 on the adjacent side. A switch 7 is fixedly connected to the top front side of the workbench 1. A button 8 is installed on the outer front side of the switch 7. Support legs 9 are fixedly connected to the four corners of the bottom of the workbench 1. A gasket 10 is fixedly connected to the bottom of the outer wall of each of the support legs 9. A fixing rod 11 is fixedly connected to the top rear side of the workbench 1.

[0040] Specifically, before the equipment is put into operation, the operator can open and close the cabinet door 5 on the front of the workbench 1 through the handle 6 on the side of the cabinet door 5 for easy storage of equipment parts or tools. The four corner legs 9 at the bottom of the workbench 1 support the entire equipment, and the pads 10 at the ends of the legs 9 enhance the stability of the equipment and prevent shaking during operation. Then, the operator can press the button 8 on the outer wall of the switch 7 on the top front of the workbench 1 to start the equipment. At the same time, the fixing rod 11 on the rear side of the top of the workbench 1 and the limiting rod 12 at the top can play an auxiliary limiting role for the rear parts of the equipment or the conveyed materials to prevent displacement. The fixed shaft 16 runs through the left and right sides of the top of the positioning frame 2073. To enhance structural stability, the bottom fixing buckle 2074 of the positioning frame 2073 is adjusted in position via the connecting plate 15 slidably connected to one side of the outer wall, temporarily fixing the sausage casing. Simultaneously, the air compressor 2075 is started. The compressor, via a support rod 2076 with a flange 13 mounted in the middle of the outer wall, reinforces the stability of the support rod 2076 and applies pressure to the adjusting frame 2078, causing the clamping frame 2079 to clamp the sausage casing sealing area. The screws 14 threaded to the bottom of the clamping frame 2079 ensure a stable clamping structure, guaranteeing the stability of equipment operation, ease of operation, and structural robustness, ensuring efficient and precise sealing operations.

[0041] Working Principle: Before starting the equipment, the filling machine 4 is used to fill the sausage casings with raw materials. The operator places the empty casings on the outlet of the filling machine 4. After starting the filling system, the minced meat and other raw materials are quantitatively injected into the casings, forming unsealed sausage embryos. The filling machine 4 controls the amount of raw materials to ensure that each sausage embryo is of the same size, avoiding the sealing effect due to too much or too little raw materials. After filling, the unsealed sausage embryos are transferred to the conveyor mechanism 3. During the movement, it is ensured that sausage embryos of different sizes can be conveyed in a straight line to the conveyor belt 204 of the conveyor mechanism 2, laying the positional foundation for subsequent precise sealing. After entering the conveying mechanism 2, the sausage is precisely moved below the sealing assembly 207. The motor 203 on the right support frame 202 starts, and its output drives the rotating shaft 206 to rotate. The rotating shaft 206 synchronously drives the conveyor belt 204 on the outer wall to circulate. The friction on the surface of the conveyor belt 204 propels the sausage embryo forward. Limiting and anti-deviation measures: Limiting rods 205 on the front and rear sides of the top of the support frame 202 form constraints from both sides of the sausage embryo, preventing lateral deviation during transport. This ensures that each sausage embryo is precisely aligned with the subsequent sealing assembly 207, avoiding sealing position deviation. When the sausage embryo is transported directly below the sealing assembly 207... The equipment enters the sealing stage, a process driven by pneumatics to achieve precise sealing. Cylinder 2072 is activated, and its pneumatic thrust drives the positioning frame 2073 at its front to slide downwards. The fixing buckle 2074 at the bottom of the positioning frame 2073 first contacts the top of the sausage embryo, temporarily fixing it to the preset position on the conveyor belt 204 through the fastening structure, preventing displacement during sealing and completing pre-sealing positioning. Simultaneously, the air compressor 2075 is activated to provide high-pressure air for the pneumatic operation. The compressor applies downward pneumatic pressure to the adjusting frame 2078 via the support rod 2076. The clamps on the front and rear sides of the adjusting frame 2078... Driven by pressure, frame 2079 clamps the sausage casing from both sides, firmly securing the sealing area and preventing wrinkles or misalignment during sealing. Air compressor 2075 transmits pneumatic thrust to pressing frame 2077, causing it to press rapidly downwards. Pressing frame 2077 is typically equipped with heating elements at its bottom. Through the combined action of pneumatic pressure, the sealing area of ​​the casing is pressed tightly, achieving a tight seal and allowing the casing to proceed to the next process. Subsequent unsealed sausage casings continue to enter sealing assembly 207 via conveyor mechanism 3 and conveyor mechanism 2. The equipment enters a cyclical operation state, achieving automated continuous sealing.

[0042] After startup, the filling machine 4 injects a measured amount of minced meat into the casing to form sausage embryos. The sausage embryos enter the conveying mechanism 3. The protective shell 301 of the conveying mechanism 3 is fixed to the top of the support frame 202 to protect the internal components. The connecting pipe 302 at the top of the protective shell 301 supports the support tube 3064 to lift the bottom of the sausage embryo and helps stabilize the overall structure. The limiting tube 303 in the middle of the inner side of the protective shell 301 plays a core supporting and positioning role. After the motor 304 fixed on the right side of its inner wall starts, the output end drives the roller 305 to rotate, driving the sausage embryo to move through friction. At the same time, the positioning component 306 in the middle of the wall of the limiting tube 303 precisely constrains the sausage embryo. The adjusting plate 3061 is fixed on the right side of the limiting tube 303 and can adjust the positioning distance to adapt to different specifications of sausage embryos. The spring 3062 at the bottom of the right side of the limiting tube 303 provides elastic pressure, which drives the limiting plate 3063 connected to the support tube 3064 to clamp the sausage embryo from both sides to prevent the conveyor from deviating and ensure that the sausage embryo enters the conveyor belt 204 of the conveying mechanism 2 in a straight line.
