Description

Technical Field

[0001] This invention relates to the field of food testing equipment technology, and in particular to a multi-station environmentally friendly aseptic food testing workbench. Background Technology

[0002] With the increasing frequency of global food trade and the continuous extension of the food industry chain, food faces more and more safety risks in production, processing, transportation, and storage. This places higher demands on food testing technologies and equipment. From an industry regulatory perspective, countries are constantly improving food safety regulations, with increasingly stringent limits on contaminants, additives, and pathogens in food. For example, my country's National Food Safety Standards have clear and stringent regulations on microbial indicators and pesticide residues in various types of food. This requires testing equipment to accurately detect trace amounts of substances exceeding the standards, ensuring the authority and accuracy of test results.

[0003] However, during food testing, various food samples may be encountered. For example, corrosive substances such as jam may accelerate the corrosion of the filter, thus increasing the frequency of maintenance by repair personnel. In addition, when testing, the edges of the cover plate may be contaminated with bacteria, which may affect subsequent food testing procedures. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by proposing a multi-station environmentally friendly aseptic food testing workbench.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-station environmentally friendly aseptic food testing workbench includes a base and a workbench. A collection box is fixedly connected to the bottom of the workbench. The collection box has an internal ramp and a filter screen for brush cleaning is fixedly connected inside. The brush is slidably connected to a support rod, and a compression spring is fixedly connected to one side of the brush. A bracket is fixedly connected to the bottom of the collection box, and an annular sliding frame is slidably connected to the bracket. A spring is fixedly connected to the bottom of the annular sliding frame, and an air bladder is installed inside the spring. An air cylinder rod is connected to the air bladder through a pipe, and an extension rod is slidably connected to the air cylinder rod. A toothed rod is engaged with the side of the annular sliding frame, and a rotating shaft is driven by the toothed rod. The end of the rotating shaft away from the toothed rod is driven by the axis of a flip plate. The collection box has cut holes for the sliding of the collection trough.

[0006] The above technical solution further includes: The bracket is rotatably connected to a rack, the rack is driven by a second belt, the end of the second belt away from the rack is driven by a rotating shaft, the rotating shaft is driven by a first belt, the end of the first belt away from the rotating shaft is driven by a flip plate, the side of the flip plate is provided with a shaft for the first belt drive connection, and the shaft of the flip plate is rotatably connected to the fixing bar.

[0007] A cover plate is provided above the workbench for covering the support rod.

[0008] A support frame is fixedly connected above the base, and a conveyor belt is provided on the side of the support frame.

[0009] A threaded rod is rotatably connected above the base, and a worktable is threadedly connected to the threaded rod. A vertical plate is slidably connected to the worktable, and a side plate is slidably connected to the end of the worktable away from the vertical plate. An electric push rod is provided above the base, and a seat is fixedly connected above the electric push rod.

[0010] A threaded rod is rotatably connected to the top of the base. The threaded rod is threaded to the worktable, and the worktable is slidably connected to the upright plate. The rotation of the threaded rod causes the worktable to slide along the upright plate, which can flexibly adjust the height of the worktable. The upright plate provides guide support to ensure that the worktable does not wobble when adjusting the height, thus improving the stability of the detection operation. The side plates can slide along the worktable to adjust the spacing, which can not only adapt to the placement requirements of different sized detection instruments, but also form a physical barrier between workstations to reduce cross-contamination between adjacent operating areas.

[0011] A collection pipe is provided on the side of the collection box.

[0012] The collection pipe directs the filtered waste liquid to an external treatment device, preventing the waste liquid from accumulating in the collection tank. The inclined design also accelerates the waste liquid discharge rate and reduces the corrosion of the tank wall by residual liquid.

[0013] The bottom of the annular sliding frame is provided with a footrest.

[0014] Increasing the foot contact area makes the force applied by the foot pedal more even, avoids jamming of the sliding frame caused by single-foot pressure, ensures stable opening or closing response of the cover, and improves the smoothness of operation.

[0015] The bottom of the brush is provided with multiple sets of bristles for the surface of the filter screen.

[0016] Multiple bristle strips can cover the entire filter screen, and together with the brush's sliding stroke, they can thoroughly clean viscous impurities such as jam. The bristle strip design can penetrate deep into the filter screen pores, preventing impurities from getting stuck and causing blockages.

[0017] The side of the collection box is provided with a slanted frame for supporting the bracket.

[0018] The inclined frame forms a triangular support for the bracket, ensuring that the bracket does not deform when placing waste boxes and disinfection tools, preventing waste from spilling due to bracket swaying, and improving the structural stability of the equipment.

[0019] The present invention has the following beneficial effects: 1. In this invention, synchronous cleaning can quickly remove corrosive impurities such as jam remaining on the filter screen surface, reduce the continuous erosion of the filter screen by acidic substances, and reduce the probability of local corrosion by centralized collection design, thereby greatly extending the filter screen replacement cycle and reducing the frequency of disassembly and maintenance by maintenance personnel due to corrosion.

[0020] 2. In this invention, the foot-operated opening mechanism avoids hand contact with the edge of the cover plate. Combined with simultaneous cleaning, it reduces the residue of impurities in the gaps of the cover plate. With the addition of circumferential ultraviolet disinfection, the detection rate of pathogens on the edge of the cover plate can be significantly reduced, preventing pathogens from being transferred through the hands and contaminating subsequent test samples, thus ensuring the sterility and accuracy of the test results.

[0036] In one embodiment, the collection box 26 is provided with a slanted bracket on its side for supporting the bracket 25.

[0037] In this embodiment, the inclined frame forms a triangular support for the bracket 25, ensuring that the bracket 25 does not deform when placing waste boxes and disinfection tools, avoiding waste spillage due to bracket shaking, and improving the structural stability of the equipment.

[0038] The working principle of the multi-station environmentally friendly aseptic food testing workbench of this invention is as follows: multiple workbenches 6 can be set on both sides of the support frame 2 for use by staff. Staff can control the rotation of the threaded rod 5 as needed, causing the workbenches 6 to move up and down on the surface of the threaded rod 5. An electric push rod is installed under the seat 8 to accommodate staff of different heights. During use, staff will pick up the food to be tested from the surface of the conveyor belt 3. When waste needs to be disposed of, staff can step on the bottom of the annular sliding frame 28, causing the annular sliding frame 28 to slide downwards and compress the spring 2. 9. The airbag 30 inside the spring 29 is compressed, and the gas inside the airbag 30 enters the air pump rod 14 through the upper air pipe. The gas then pushes the brush 12 with the extension rod 15, and the compression spring 16 is compressed. The brush 12 slides along the inner wall of the collection box 26 to the side near the fixing strip 11. At the same time, the annular sliding frame 28 slides downward and engages with the toothed rod 24. The rotation of the toothed rod 24 drives the rotating shaft 22 to rotate via the second belt 23. The rotation of the rotating shaft 22 continues to drive the shaft on one side of the flip plate 20 to rotate via the first belt 21. Finally, as the annular sliding frame 28 continues to descend... Rotate the flip plate 20 along the axis to expose the interior of the collection box 26, and bring the brush 12 to the side closest to the fixing bar 11. Pour the waste onto the surface of the filter screen 17, then release the foot from the foot on the annular sliding frame 28. When the annular sliding frame 28 is no longer under downward tension, the elastic potential energy accumulated in the spring 29 is released, and the spring 29 lifts the annular sliding frame 28, causing it to slide upwards. The airbag 30 is no longer compressed, and simultaneously, the compression spring 16 releases its elastic potential energy, pushing the brush 12 and indirectly pushing the extension rod 15. The extension rod 15 then pushes the gas inside the air pump rod 14 along... The air tube above the annular sliding frame 28 is pushed into the airbag 30, while the brush 12, pushed by the compression spring 16, gradually moves away from one end of the fixing bar 11. The brush 12 cleans the surface of the filter screen 17 into the collection tank 18, thereby preventing acidic substances such as jam from corroding and clogging the surface of the filter screen 17, thus increasing the maintenance difficulty. In addition, the upward sliding of the annular sliding frame 28 will mesh with the toothed rod 24, thereby driving the second belt 23 to drive the transmission. The second belt 23 then drives the first belt 21 to drive the transmission through the rotating shaft 22. The first belt 21 continues to drive the shaft of the flip plate 20 to rotate, thereby covering the opening of the surface of its collection box 26.
