Description

Technical Field

[0001] The present invention relates to the technical field of bamboo fiber antibacterial detection, in particular to a bamboo fiber antibacterial detection device and a detection method thereof. Background Art

[0002] Bamboo fiber is cellulose fiber extracted from naturally grown bamboo. Bamboo fiber has good air permeability, instant water absorption, strong wear resistance and good dyeing properties. It has natural antibacterial, antibacterial, mite removal, deodorization and UV resistance functions. The antibacterial properties of bamboo fiber can be tested through antibacterial testing equipment to measure the antibacterial properties of the bamboo fiber.

[0003] For example, the Chinese authorized patent with announcement number CN214881503U, "Antimicrobial detection device for soft sterilization and flame-retardant fabric clothing for chefs", includes a bottom plate to facilitate the placement of connecting rods. A top plate is provided above the bottom plate to facilitate the placement of connecting seats, and the bottom plate and the top plate are fixedly connected by connecting rods to facilitate the placement of the base plate and the cover plate. Two connecting seats are fixedly connected to one side of the bottom of the top plate to facilitate the placement of round rods. There are four connecting rods, and the four connecting rods are respectively located at the four corners between the bottom plate and the top plate to enhance the stability of the overall device.

[0004] Although the above-mentioned existing technology can be used to detect antibacterial fabrics and clothing, bamboo fiber is smaller in size than fabrics and clothing, and it is inconvenient to fix and place the bamboo fiber. In addition, the antibacterial detection device is exposed to the air. Although a control experiment is set up, external interference acts on both samples, so it is easily interfered by external factors. Therefore, it does not meet the existing needs. In this regard, we propose a bamboo fiber antibacterial detection device and a detection method. Summary of the Invention

[0014] Preferably, a linkage plate is provided in front of the fixing seat, and the linkage plate is welded and fixed to one end of the pulling block located outside the fixing seat.

[0015] Preferably, a first rotating shaft is provided at the middle position below the two linkage plates, and the first rotating shaft is rotatably connected to the moving chamber, one end of the first rotating shaft passes through and extends to the outside of the box body, and an anti-sliding block is welded to the end of the first rotating shaft located outside the box body.

[0017] Preferably, a guide rod is welded to one side of the second rotating shaft, the guide rod passes through the L-shaped moving block, and the guide rod is in sliding fit with the L-shaped moving block.

[0018] The detection method of the bamboo fiber antibacterial detection device includes the following steps:

[0019] Step 1. Open the box door, hold the anti-slider and rotate it. The rotation of the anti-slider will drive the synchronous rotation of the first rotating shaft, and the rotation of the first rotating shaft will drive one of the transmission gears to rotate. Under the meshing transmission between the three transmission gears, the remaining two transmission gears can be rotated synchronously. The rotation of the remaining two transmission gears will drive the second rotating shaft to rotate the single-threaded transmission rod synchronously. The rotation of the single-threaded transmission rod will rotate the L-shaped moving block. Under the limiting and guiding action of the guide rod, the rotational motion of the L-shaped moving block can be converted into horizontal linear motion, so that the detection table can be moved inside the detection room through the movement of the L-shaped moving block, and then the front end of the detection table can be moved out of the detection room;

[0020] Step 2: Pull the linkage plate to drive the pulling block to move forward, so that the first extrusion block 16 can move synchronously, so that one of the sliding connection blocks slides on the first slide rod and squeezes the first spring, which can release the extrusion limit of the second extrusion block. Under the pull of the second spring, one of the sliding connection blocks can slide on the second slide rod, so that the second extrusion block drives the limit block to move out of the limit groove, thereby releasing the limit of the culture dish and taking out the culture dish. Repeat the operation to take out another culture dish;

[0021] Step 3: Add culture medium into one of the culture dishes and add bamboo fiber sample into the other culture dish. Add appropriate amount of bacteria into the two culture dishes simultaneously. The bacteria can be Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, etc. After adding, put the culture dishes back into the fixed seat and perform preliminary positioning through the magnetic iron sheet. Under the elastic recovery action of the first spring, the first extrusion block will return to its original position, so that the second extrusion block drives the limit block into the interior of the limit groove to complete the fixation of the culture dishes. By rotating the anti-sliding block, the front end of the detection platform can be moved back into the detection chamber.

[0022] Step 4: Culture the bacteria that enter through the culture dish. The temperature of the culture dish can be detected by an infrared thermometer. When the temperature is inconsistent or too low, the electric heating rod in the heating chamber can be started to increase the temperature. The temperature variable of the culture dish can be controlled in conjunction with the detection of the infrared thermometer. The high-definition camera can record the culture status of bacteria on the culture medium and bamboo fiber sample, and conduct comparative analysis to derive the antibacterial ability of the bamboo fiber.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention opens a moving chamber below the detection chamber. The first rotating shaft can be rotated by rotating the anti-sliding block. Under the meshing transmission of the transmission gear, the two single-threaded transmission rods can be rotated synchronously, so that the L-shaped moving block can move on the single-threaded transmission rod. The movement of the L-shaped moving block can move the front end of the detection platform out of the box, thereby providing a larger space for placing or taking bamboo fiber samples, avoiding operations in a small detection chamber, and making it more convenient to place or take bamboo fiber samples.

[0025] 2. The present invention provides a fixing seat on the testing table. When placing or taking bamboo fiber samples, the limiting block can be moved out of or into the limiting groove by simply pulling the linkage plate. The culture dish can be fixed by the cooperation of the limiting block and the limiting groove, and the culture dish can be conveniently taken out, making it more convenient to place or take bamboo fiber samples. At the same time, the lower side of the rear end of the culture dish and the magnetic iron sheet provided in the groove of the fixing seat can preliminarily fix the culture dish, making it convenient to move the limiting block out of or into the limiting groove.

[0026] 3. The present invention has a door movably connected to the front end of the box body. When testing, the door is closed to isolate the testing room from the outside world, reducing interference from external factors such as dust. At the same time, the two culture dishes provided serve as a control, making the test more accurate. The detection of the infrared thermometer can ensure that the temperatures of the two culture dishes are consistent, thereby controlling the temperature variable to make the test more accurate.
