Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to vacuum equipment for food processing production lines. Background Technology

[0002] Currently, in the food processing industry, vacuuming is commonly used to remove air from packaging in order to extend product shelf life and maintain flavor. With the rapid development and technological advancements in the food processing industry, market demands for vacuuming equipment are increasing. These demands not only for efficient and rapid vacuuming but also for miniaturization, intelligent operation, and energy-saving and environmentally friendly features. While existing vacuuming equipment can meet basic requirements, there is still significant room for improvement in efficiency and cost reduction.

[0003] Existing technical solutions: Currently, the most common vacuum pumping devices on the market are mainly manual, semi-automatic, and fully automatic.

[0004] Manual equipment is simple to operate but inefficient, making it unsuitable for large-scale production environments. Semi-automatic equipment achieves partial automation of the vacuuming process through a simple electrical control system, improving efficiency but still susceptible to human error. Fully automatic equipment employs advanced sensing technology and a PLC control system, achieving a high degree of automation from material conveying and positioning clamping to vacuum sealing, significantly improving production efficiency. However, these traditional devices generally suffer from high energy consumption and complex maintenance, limiting their application scope and development potential.

[0005] Limitations of existing technology: Although fully automated vacuum equipment has shown significant advantages in many aspects, its high cost, complex system structure, and high energy consumption have become key factors restricting its widespread application. In addition, existing equipment usually lacks sufficient flexibility to adapt to products of different shapes and sizes, making it difficult for companies to make quick adjustments when facing diverse market demands. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a vacuum equipment for food processing production lines, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0007] To achieve the above objectives, this application adopts the following technical solution: a vacuum equipment for a food processing production line, comprising a frame and a conveyor belt, a top plate fixedly installed on the top of the frame, a sealing chamber fixedly installed on the top of the top plate, an opening on the outer side of the sealing chamber, a cover plate rotatably connected to the top of the sealing chamber, a fixing plate fixedly installed on the outer side of the sealing chamber, a hydraulic cylinder fixedly installed on the top of the fixing plate, a vacuum pump fixedly installed in the inner cavity of the frame, a pipe fixedly connected to the output end of the vacuum pump, a control cabinet fixedly installed on the outer wall of the frame, and a PLC controller and a display screen fixedly installed on the inner wall of the control cabinet.

[0008] In a preferred embodiment, a positioning plate is fixedly installed on the outside of the sealing chamber, and a hydraulic cylinder is fixedly connected to the bottom of the positioning plate. A baffle is fixedly connected to the output shaft of the hydraulic cylinder, and the outside of the baffle is attached to the outer wall of the frame.

[0009] By adopting the above technical solution, the bottom of the driven hydraulic cylinder two can be moved downward to make it fit against the top of the conveyor belt, thereby sealing the feed hole of the top sealing chamber of the conveyor belt.

[0010] In a preferred embodiment, the inner wall of the sealing chamber is uniformly coated with a Teflon anti-stick layer, and two opening and closing ears are symmetrically fixedly connected to the top of the cover plate, with the output end of the hydraulic cylinder rotatably connected to the bottom of the opening and closing ears.

[0011] By adopting the above technical solution, food residue can be prevented from adhering to the inner wall of the sealed chamber. By driving the hydraulic cylinder to push the opening and closing ears upward, the cover can be opened to release the gas in the sealed chamber. The whole process does not require manual operation and has a high degree of intelligence.

[0012] In a preferred embodiment, the end of the pipe furthest from the vacuum pump is fixedly connected to the sealing chamber, a pressure gauge is fixedly installed on the inner wall of the pipe, and sealing rings are provided at the connections between the pipe and the vacuum pump and the sealing chamber.

[0013] By adopting the above technical solution, the operation of the vacuum pump can be achieved by using pipelines to extract gas from the sealed chamber until the preset vacuum level is reached. After evacuation, inert gas is immediately injected or heat sealing is performed.

[0014] In a preferred embodiment, four casters are symmetrically fixedly installed at the bottom of the frame.

[0015] By adopting the above technical solution, the device can be easily moved to any location for use without manual handling, thus reducing manpower consumption.

[0016] In a preferred embodiment, a protective door is rotatably connected to the outside of the control cabinet, and a handle is fixedly installed on the outside of the protective door.

[0017] By adopting the above technical solution, the protective door can seal the outside of the control cabinet, thereby preventing external dust and impurities from entering the inner cavity of the control cabinet and coming into contact with the PLC controller and display screen, thus improving the protection effect of the PLC controller and display screen.

[0018] In a preferred embodiment, one side of the conveyor belt is disposed on the inner wall of the opening, and a maintenance plate is fixedly installed on the outer side of the frame by two bolts.

[0019] By adopting the above technical solution, the inspection plate can be removed after the bolts are removed, which facilitates the inspection and maintenance of the frame's internal cavity and improves the convenience of maintenance.

[0020] The beneficial effects of this application are:

[0021] 1. This food processing production line uses vacuum equipment. By driving a vacuum pump, it can extract gas from the sealed chamber through pipelines until a preset vacuum level is reached. After evacuation, inert gas is immediately injected or heat sealing is performed. The pressure gauge can monitor the pressure of gas flow in the pipeline in real time to ensure no leakage. It significantly reduces the size of the equipment, improves space utilization, speeds up the vacuuming process, and increases the output per shift. Furthermore, due to the adoption of energy-saving design, the overall operating cost is effectively reduced, resulting in significant economic benefits.

[0022] 2. The vacuum equipment used in this food processing production line can be set with parameters and monitored via a PLC controller and display screen. The conveyor system is responsible for sending the items to be processed into the sealed chamber. When not in use, the protective door can be closed and fitted to the control cabinet, thus protecting the PLC controller and display screen and ensuring their service life. The inspection plate can be disassembled by removing the bolts, making it convenient for users to inspect and maintain the vacuum pump, as well as to replace and clean the filter element. This simplifies the equipment maintenance process and extends its service life. Attached Figure Description

[0031] See Figure 5 A positioning plate 10 is fixedly installed on the outside of the sealing chamber 4. A hydraulic cylinder 11 is fixedly connected to the bottom of the positioning plate 10. A baffle 12 is fixedly connected to the output shaft of the hydraulic cylinder 11. The outside of the baffle 12 is attached to the outer wall of the frame 1, so that the bottom of the baffle 12 driven by the hydraulic cylinder 11 can be moved downward and attached to the top of the conveyor belt 20, thereby sealing the feed hole of the sealing chamber 4 at the top of the conveyor belt 20.

[0032] See Figure 5 The inner wall of the sealed chamber 4 is uniformly coated with a Teflon anti-stick layer 6. Two opening and closing ears are symmetrically fixed to the top of the cover plate 7. The output end of the hydraulic cylinder 9 is rotatably connected to the bottom of the opening and closing ears. The Teflon anti-stick layer 6 prevents food residue from adhering to the inner wall of the sealed chamber 4. By driving the hydraulic cylinder 9 to push the opening and closing ears upward, the cover plate 7 can be opened to release the gas in the inner cavity of the sealed chamber 4. The whole process does not require manual operation and has a high degree of intelligence.

[0033] See Figure 3 and Figure 4 The end of the pipe 14 away from the vacuum pump 13 is fixedly connected to the sealing chamber 4. A pressure gauge 15 is fixedly installed on the inner wall of the pipe 14. Sealing rings are provided at the connection between the pipe 14, the vacuum pump 13 and the sealing chamber 4, so that the vacuum pump 13 can use the pipe 14 to extract the gas in the sealing chamber 4 until the preset vacuum degree is reached. After the evacuation is completed, inert gas is immediately injected or heat sealing is performed.

[0034] See Figure 1 and Figure 2 Four casters 2 are symmetrically fixed to the bottom of the frame 1, making it easy to move the device to any location for use without manual handling, thus reducing manpower consumption.

[0035] See Figure 2 and Figure 3 A protective door 19 is rotatably connected to the outside of the control cabinet 16. A handle is fixedly installed on the outside of the protective door 19, so that the protective door 19 can close the outside of the control cabinet 16, thereby preventing external dust and impurities from entering the inner cavity of the control cabinet 16 and coming into contact with the PLC controller 17 and the display screen 18, thus improving the protection effect of the PLC controller 17 and the display screen 18.

[0037] Working principle: First, the device can be moved to the location using four casters 2. Then, the conveyor belt 20 smoothly feeds the items to be processed into the sealing chamber 4. After reaching the predetermined position, the hydraulic cylinder 9 is driven to move the cover plate 7 downward, closing the top of the sealing chamber 4. At the same time, the hydraulic cylinder 11 is driven to move the baffle 12 downward, sealing the feed hole of the sealing chamber 4 at the top of the conveyor belt 20. Next, the vacuum pump 13 is driven to extract the gas in the sealing chamber 4 through the pipe 14 until the preset vacuum degree is reached. After evacuation, inert gas or other gas is immediately injected. The system undergoes heat sealing. Pressure gauge 15 can monitor the gas pressure inside pipe 14 in real time to ensure no leakage. PLC controller 17 and display screen 18 can set parameters and monitor the status of conveyor belt 20 system responsible for sending the items to be processed into sealed chamber 4. When not in use, protective door 19 can be closed and fitted to control cabinet 16, thus protecting PLC controller 17 and display screen 18 and ensuring their service life. The inspection plate 21 can be disassembled by removing bolts, which facilitates the user's maintenance of vacuum pump 13 and the replacement and cleaning of its filter element.
