[0002] Plastic bottles are widely used in the medical and food industries, and their technological advantages (such as aseptic properties and functional design) have driven increased market penetration. Currently, plastic bottles are sterilized using high-pressure steam sterilization. However, high temperatures can deform or damage the plastic material. Therefore, ensuring the bottle shape remains consistent and minimizing deformation is crucial when using sterilization trays. However, existing sterilization trays typically place plastic bottles back-to-back during sterilization. This arrangement results in uneven heating and poor circulation of steam or disinfectant, easily creating sterilization dead zones. This leads to a lower product yield after sterilization, which is detrimental to sustainable development. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Reference Figure 1-4 A special sterilization and stacking tray for plastic bottles, designed specifically for the sterilization of plastic bottles (specifically, for bottle 5), features a stable structure, good air permeability, and easy adjustment and stacking. It effectively improves the efficiency and quality of plastic bottle sterilization (specifically:
[0023] The tray includes a perforated mesh plate 1, which serves as the core load-bearing component of the tray. It is made of high-strength, corrosion-resistant metal materials, such as stainless steel, to ensure that it will not rust or deform during long-term use. It can support a certain weight of plastic bottles 5, and its surface is finely polished to make it smooth and flat, preventing scratches on the surface of the plastic bottles 5. Several permeable holes 10 are provided on the perforated mesh plate 1, which can ensure that steam or disinfectant can pass smoothly during the sterilization process to achieve a comprehensive and efficient sterilization effect, and also prevent the plastic bottles 5 from falling out of the holes. Preferably, the permeable holes 10 are circular holes and are evenly distributed on the perforated mesh plate 1.
[0024] Several grids 4 are provided from one side of the perforated mesh plate 1 to the other side. These grids not only provide stable support for the plastic bottles 5, preventing them from rolling or tipping over during sterilization, but also increase the strength of the grids 4 to a certain extent and extend the service life of the tray. Preferably, the grids 4 are arranged in a U-shape, with a sterilization gap between two adjacent grids 4 to facilitate the side-by-side placement of the plastic bottles 5. The size of the sterilization gap is designed according to the specifications of common plastic bottles 5 to ensure that the plastic bottles 5 can be arranged tightly, making full use of the tray space, while ensuring that steam or disinfectant can flow freely between the plastic bottles 5 to achieve comprehensive sterilization.
[0025] Several reinforcing ribs 6 are fixed to the bottom of the perforated mesh plate 1 by welding. The reinforcing ribs 6 include transverse reinforcing ribs and longitudinal reinforcing ribs arranged at 90° to form a grid structure. The reinforcing ribs 6 are made of the same material as the perforated mesh plate 1 and are firmly connected to the perforated mesh plate 1 by welding. This can significantly enhance the load-bearing capacity of the perforated mesh plate 1, prevent it from deforming when containing plastic bottles 5, and ensure the stability and reliability of the pallet during long-term use.
[0026] To provide stable frame support for the entire pallet, a reinforcing frame 3 is fixedly installed around the perimeter of the perforated mesh plate 1 to support it. Vertical corner posts 2 are fixedly installed at each of the four corners of the reinforcing frame 3. The corner posts 2 are made of hollow square tubing, which reduces the overall weight of the pallet while ensuring sufficient strength, facilitating handling and operation. Preferably, the reinforcing frame 3 is a rectangular frame formed by welding four stainless steel tubes and the corner posts 2 end to end. The stainless steel tubes have high strength and good corrosion resistance, which can enhance the edge strength of the pallet and prevent deformation during handling and use.
[0027] Preferably, threaded posts I7 are screwed onto the top of the four corner posts 2 for easy height adjustment. The threaded posts I7 are made with high-precision thread processing technology, with clear threads, uniform spacing, and smooth rotation. By rotating the threaded posts I7, the height of the tray can be flexibly adjusted according to the sterilization requirements of different specifications of plastic bottles 5 to adapt to different sterilization equipment and process conditions. More preferably, several threaded posts II9 are screwed onto the top of the reinforcing frame 3 for easy height adjustment. The structure of the threaded posts II9 is the same as that of the threaded posts I7, and they can cooperate with the threaded posts I7 to further meet different height adjustment needs, so that the tray can adapt to more diverse usage scenarios. At the same time, the structure of the threaded posts II9 and the setting of the threaded posts I7 also leave a certain gap between the two trays stacked on top of each other, which facilitates disassembly and assembly operations.
[0028] To facilitate operation, length markings are provided on both threaded post I7 and threaded post II9. The length markings are clear and precise, which can help operators to accurately adjust the height of the tray according to the sterilization requirements of different sizes of plastic bottles 5, thereby improving the accuracy and efficiency of operation.
[0029] In actual use, a locating pin 8 is provided at the top of the threaded column I7, and locating holes for engaging with the locating pin 8 are provided at the bottom of the four corner columns 2. Guide slopes are provided around the locating holes to facilitate quick and accurate insertion of the locating pin 8. When multiple pallets are stacked, the insertion of the locating pin 8 into the locating holes ensures accurate relative positioning between the pallets, preventing displacement or tipping during stacking and improving stacking stability and safety. Preferably, the locating pin 8 is cylindrical, and its diameter and length are precisely designed, with a hardened surface treatment to improve its wear resistance and service life.
[0030] The plastic bottle sterilization and folding tray provided in this application is suitable for automated loading and unloading operations, which helps to reduce the number of workers and improve sterilization efficiency. Its specific usage process is as follows:
[0031] Before use, adjust the height of the tray by rotating the threaded column I7 and threaded column II9 according to the required specifications of the plastic bottle 5 to be sterilized. The operator can accurately adjust the tray to the appropriate height according to the length scale markings on the threaded column to ensure that the plastic bottle 5 can cooperate well with the sterilization equipment during the sterilization process, and at the same time ensure that the steam or disinfectant can fully contact all parts of the plastic bottle 5.
[0032] Place the plastic bottles 5 to be sterilized side by side between the grids 4 on the tray, and use the grids 4 to fix the plastic bottles 5 in place, ensuring that the plastic bottles 5 are arranged neatly and stably and will not move or tip over during handling or sterilization. Since there are appropriate sterilization gaps between the grids 4, steam or disinfectant can flow freely between the plastic bottles 5 to achieve complete sterilization.
[0033] If a large number of plastic bottles 5 need to be sterilized at the same time, multiple trays can be stacked. When stacking, align the positioning holes at the bottom of the four corner posts 2 of the upper tray with the positioning pins 8 at the top of the threaded posts I7 of the lower tray, and slowly lower the upper tray so that the positioning pins 8 are accurately inserted into the positioning holes. The cooperation between the positioning pins 8 and the positioning holes can ensure the accurate relative position between the trays, prevent the trays from shifting or tipping over during stacking, and improve the stability and safety of stacking.
[0034] Place the tray (or stacked tray group) with the plastic bottles 5 on it into the sterilization equipment and sterilize it according to the operating procedures of the sterilization equipment. During the sterilization process, steam or disinfectant can be evenly applied to all parts of the plastic bottles 5 through the water-permeable holes 10 on the perforated mesh plate 1 and the sterilization gap between the grid 4, so as to achieve efficient and comprehensive sterilization effect.
[0035] After sterilization, remove the tray from the sterilization equipment. After the plastic bottles 5 have cooled down, remove the plastic bottles 5 from the tray and clean and disinfect the tray for future use.
