Description

Technical Field

[0001] This invention relates to the field of food testing technology, specifically to a conveying device for food testing. Background Technology

[0002] Food safety testing involves detecting harmful substances in food according to national standards, primarily focusing on harmful and toxic indicators such as heavy metals and aflatoxin. An important aspect of food science and engineering is the introduction and application of chemical unit operations, and the development of food engineering unit operations, thereby promoting the food industry towards large-scale, continuous, and automated production.

[0003] In food testing, reagent preparation and analysis are usually conducted in the same location, allowing for quick analysis after reagent preparation. However, in large-scale food testing, the workload is typically substantial, with a large volume of reagents to be prepared. Therefore, reagent preparation and analysis cannot be carried out quickly in the same area. Instead, they need to be conducted in two separate locations using an assembly line approach: one group handles reagent preparation, while another handles analysis. This process wastes considerable manpower during reagent transportation. Furthermore, because reagents require different testing environments—for example, clarifying reagents and mixed solutions need to be remixed or allowed to settle after being transported to the testing location—the process is repeated, further wasting time. Therefore, a device is needed to avoid these issues.

[0004] Therefore, it is necessary to design a food testing transport device that is practical and efficient in transporting food testing sample reagents. Summary of the Invention

[0027] Please see Figure 1-6 The present invention provides a technical solution: a conveying device for food testing, comprising a first motor 1 and a second motor 3. The output end of the first motor 1 is fixedly connected to a first transmission roller 2, and the output end of the second motor 3 is fixedly connected to a second transmission roller 4. The outer walls of the first transmission roller 2 and the second transmission roller 4 are fitted with transmission strips 5.

The front side of the outer wall of the counterweight 902 contacts the rear side of the outer wall of the transmission bar 5. A connecting arm 903 is fixedly connected to the front end of the fixing rod 901. The right side of the connecting arm 903 is rotatably connected to the first connecting rod 904 via a bearing.

[0029] The holding mechanism 907 includes a connecting pile 701. The upper end of the connecting pile 701 is rotatably connected to the lower inner wall of the connecting sleeve 906 via a bearing. A crossbar 702 is fixedly connected to the lower end of the connecting pile 701. A drop arm 703 is fixedly connected to the outer wall of both the front and rear ends of the crossbar 702.

A driving mechanism 708 is provided on the outer wall of the drop arm 703. The mass of the counterweight ball 707 is greater than the sum of the masses of the bottom box 705 and the cover 706. The center of the bottom box 705 is located below the center of the connecting pile 701.

[0030] The drive mechanism 708 includes a fixed base 801. The lower side of the fixed base 801 is fixedly connected to the outer wall of the crossbar 702. A third motor 802 is fixedly connected to the upper side of the fixed base 801. A transmission rod 803 is fixedly connected to the output end of the third motor 802. A transmission belt 804 is sleeved on the outer wall of the transmission rod 803. A sliding groove 805 is opened on the outer wall of the vertical arm 703. A slide seat 806 is slidably connected to the inner wall of the sliding groove 805. A spring 807 is fixedly connected to the upper end of the slide seat 806. The upper end of the spring 807 is fixedly connected to the upper side of the inner wall of the sliding groove 805. A connecting shaft 809 is fixedly connected to the outer wall of the slide seat 806. A transmission roller 808 is rotatably connected to the outer wall of the connecting shaft 809 through a bearing. The lower side of the transmission belt 804 is sleeved on the outer wall of the transmission roller 808. The outer wall of the transmission roller 808 and the outer wall of the transmission rod 803 are connected by transmission belt 804. A limit mechanism 810 is also provided on the vertical arm 703.

[0031] The limiting mechanism 810 includes a limiting post 101, an installation port is provided in the middle of the hanging arm 703, and the two ends of the hanging arm 703 are fixedly connected to the inner wall of the installation port. Two limiting grooves 102 are provided on the outer wall of the limiting post 101. A second connecting rod 103 is rotatably connected to the outer wall of the limiting post 101 through a bearing. A limiting strip 104 is fixedly connected to the inner wall of the second connecting rod 103. The outer wall of the limiting strip 104 contacts the inner wall of one of the limiting grooves 102. One end of the second connecting rod 103 extends to the outside of the installation port, and the end of the second connecting rod 103 located outside the installation port is rotatably connected to a limiting roller 105 through a bearing. The outer wall of the limiting roller 105 contacts the inner outer wall of the transmission belt 804. The transmission roller 808, the limiting roller 105, and the transmission rod 803 are connected by transmission through the transmission belt 804.

[0032] In use, the sample reagent is sealed and placed inside the bottom box 705. Then, the cap 706 is rotated into the bottom box 705 and tightened. At this time, the first motor 1 and the second motor 3 are started, which drive the first transmission roller 2 and the second transmission roller 4 to drive the transmission bar 5 to operate. In turn, the transmission bar 5 drives the conveying mechanism 9 to move, so that the reagent in the bottom box 705 is moved from the first transmission roller 2 to the second transmission roller 4, or from the second transmission roller 4 to the first transmission roller 2, so as to achieve the purpose of rapid transfer of the test sample.

[0033] During sample transport, the bottom box 705 remains level due to the weight of the material it contains and the counterweight ball 707. Furthermore, since the outer wall of the first connecting rod 904 is rotatably connected to the outer wall of the connecting arm 903 via a bearing, and the outer wall of the connecting arm 903 remains perpendicular to the outer wall of the adjacent transmission bar 5, the bottom box 705 remains stable during the movement of the transport mechanism 9. This ensures the stability of the reagents during transport and guarantees safety during the transport process.

[0034] Before transporting the sample, since the outer wall of the connecting pile 701 and the inner wall of the connecting sleeve 906 are connected by a bearing, the bottom box 705 can be rotated to an angle that is easy to pick up and put down before starting the third motor 802. The third motor 802 drives the transmission rod 803 to rotate, which in turn drives the transmission belt 804 and the transmission roller 808 to rotate rapidly. The transmission rollers 808 on both sides rotate rapidly at the same time. Due to the conservation of angular momentum, the deflection and swaying of the bottom box 705 can be reduced during the transport of the bottom box 705, which makes it easier for personnel to operate, speeds up the operation process, and keeps the bottom box 705 stable, reducing the deflection of the bottom box 705. For solutions that need to be settled and clarified, the amount of swaying during transport can be reduced.

[0035] When the mixed solution needs to be moved during use, to prevent the solution from clarifying during transportation, the second connecting rod 103 can be pressed down, causing the limiting strip 104 to deform and move into the lower limiting groove 102. At this time, the second connecting rod 103 deflects downward, and the limiting roller 105 moves closer to the rotating pile 704. At this time, the transmission belt 804 is relaxed, and the spring 807 pushes the slide 806 downward due to its elastic rebound. This causes the lowered slide 806 to drive the transmission roller 808 to contact the outer wall of the rotating pile 704. At this time, the third motor 802 drives the rotating pile 704 to rotate through the transmission rod 803, transmission belt 804, and transmission roller 808, which can make the bottom box 705 rotate continuously during transportation, thereby preventing the solution from clarifying and reducing subsequent time.
