Description

Technical Field

[0001] This utility model relates to the field of antibacterial detection technology, specifically to an antibacterial detection device with antibacterial coated paper. Background Technology

[0002] Coated paper is a composite material formed by uniformly coating PE plastic particles onto the surface of paper through a casting process. It belongs to the paper-plastic composite material category and is commonly used in industries such as medical, biotechnology, food packaging, electronics, and printing. When coated paper is used in the food packaging industry, the antibacterial properties of the coated paper are crucial. Antibacterial testing of coated paper usually requires specialized testing equipment, but most existing testing equipment on the market has an overly simple structure. During the testing process, bacterial suspensions can easily flow on the coated paper, changing their initial positions and leading to inaccurate testing. To improve this situation, an antibacterial testing device for antibacterial coated paper is proposed.

[0003] As disclosed in the authorization announcement number CN118562606B, an antibacterial testing device and method for coated paper includes a fixed base, on which multiple testing units are provided. Each testing unit is slidably connected to a paper positioning mechanism. A paper shaping mechanism is fixedly installed at the top rear end of the fixed base for shaping the coated paper sample. A bacterial injection guiding mechanism is also installed at the top center of each testing unit.

[0004] Although it achieves the goal of quickly forming spherical grooves on the coated paper sample by designing matching paper positioning and shaping mechanisms, ensuring that the bacterial suspension remains in a fixed position and will not escape even when shaken, it can ensure the stability of the residence time and position of the bacterial suspension in the designated area on the coated paper sample, thereby ensuring the accuracy of the test results during subsequent sampling and evaluation.

[0005] However, this does not solve the problem that existing antibacterial testing equipment is not conducive to the convenient pressing and molding of the coated paper into grooves during use, which is not conducive to maintaining the stability of the bacterial suspension during testing, thus affecting the detection effect and convenience. Utility Model Content

[0006] The purpose of this invention is to provide an antibacterial detection device with antibacterial coated paper, in order to solve the problem mentioned in the background art that the antibacterial detection device is not convenient to press the coated paper into grooves in sequence, which is not conducive to maintaining the stability of the bacterial suspension during detection, thus affecting the detection effect and convenience.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide an antibacterial testing device with antibacterial coated paper, including a placement seat and a heating chamber. The heating chamber is located on one side of the placement seat, and a support ring is installed at the top of the placement seat. Multiple sets of placement bowls are installed at equal intervals on the top of the placement seat on one side of the support ring. Each placement bowl has a retaining ring on its surface, and the retaining ring is slidably connected to the placement bowl. A limiting ring is provided inside the support ring, and the limiting ring is slidably connected to the support ring. A toothed ring is installed at the top of the limiting ring. A stepper motor is installed on the outer wall of the placement seat.

[0008] Furthermore, a drive shaft is installed at the output end of the stepper motor, and gears are fitted onto the surface of the drive shaft.

[0009] Furthermore, the gear meshes with the gear ring, and a load-bearing frame is mounted on the top of the gear ring.

[0010] Furthermore, a servo motor is provided at the top of the support frame, and the servo motor is fixedly connected to the support frame.

[0011] Furthermore, a lead screw is installed at the output end of the servo motor, and the lead screw is movably connected to the support frame.

[0012] Furthermore, a threaded sleeve is fitted onto the surface of the lead screw, and the threaded sleeve is threadedly connected to the lead screw.

[0013] Furthermore, an L-shaped bracket is mounted on the surface of the threaded sleeve, and the L-shaped bracket is slidably connected to the support frame.

[0014] Furthermore, a sleeve is installed at the bottom end of the L-shaped frame, and the lead screw can extend into the interior of the sleeve.

[0015] Furthermore, a pressing ball is provided at the bottom end of the sleeve, and the pressing ball is fixedly connected to the sleeve.

[0016] Furthermore, a bottom groove is provided at the center of the inside of each bowl, and the pressing ball can penetrate deep into the bottom groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the antibacterial detection device not only realizes the convenient sequential pressing and groove forming of the coated paper, which facilitates the maintenance of the stability of the bacterial suspension during detection, but also improves the detection effect and the convenience of detection.

[0018] Cut the coated paper to be tested into several squares. Place multiple sets of placement bowls sequentially on the surface of the placement base. Remove the retaining ring from the placement bowl, then lay the coated paper sequentially on the surface of the placement bowl. Press the retaining ring back onto the surface of the placement bowl to fix the coated paper on the placement bowl. Follow the above steps to install the coated paper on multiple sets of placement bowls sequentially. A stepper motor drives the drive shaft to rotate, which in turn drives the gear to rotate. The gear drives the gear ring to rotate, which in turn moves the support frame and the pressing ball, causing the pressing ball to move to... The servo motor drives a lead screw to rotate directly above the bowl. The lead screw, through a threaded sleeve, moves an L-shaped frame and a sleeve downwards. The sleeve then moves a pressing ball downwards to contact the coating paper, deforming it. The pressing ball engages inside the bottom groove, pressing the coating paper into a concave shape. Afterwards, the servo motor is reversed and turned back, resetting the pressing ball. This process, performed by the servo motor and stepper motor, sequentially presses the coating paper placed on different bowls into shape. Then, the bacterial suspension is... The bacterial suspension is sequentially dripped into the grooves on the surface of the coated paper. The grooves prevent the bacterial suspension from flowing, which would affect the detection results. A placement bowl is then used to place the coated paper and bacterial suspension into a heating chamber, which heats the samples to simulate different temperature environments and test bacterial survival under varying conditions. After heating, the coated paper sample is left in contact with the bacterial suspension for several hours to several days to simulate real-world contact. After a certain period, the coated paper sample is removed from the testing device, and a sample is cut from the detection area. The bacteria are then released from the sample using a washing or shaking method. A plate count or coating method is then used to assess bacterial survival on the coated paper. This completes the operation of the antibacterial testing device. The device allows for convenient sequential pressing and groove formation of the coated paper, preventing the bacterial suspension from flowing on the surface, maintaining the stability of the bacterial suspension during detection, and improving both the detection effect and convenience.
