Abstract
Description
Technical Field
[0001] This utility model relates to a disinfection device, specifically a disinfection device for processing plastic bottles, and belongs to the technical field of plastic processing equipment. Background Technology
[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding the corresponding organic solvents, they are heated at high temperatures and then made into plastic containers through plastic molds by blow molding, extrusion blow molding, or injection molding. They are mainly used as disposable plastic packaging containers for liquids or solids such as beverages, food, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles have the characteristics of being not easily broken, low cost, high transparency, and made from food-grade raw materials.
[0003] However, existing food-grade plastic bottles require sterilization during production before they can be used for food storage. Sterilization requires manual operation, and the prolonged contact between the sterilizing solution and the human body can corrode workers' hands and cause harm. To address these issues, we provide a sterilization device for plastic bottle processing. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a sterilization device for plastic bottle processing, the specific technical solution of which is as follows:
[0005] A sterilization device for processing plastic bottles includes a base plate, an elongated plate connected to the upper surface of the base plate, a motor connected to the outer surface of the elongated plate, a rotating rod connected to the output shaft end of the motor, a threaded rod connected to one end of the rotating rod, a threaded plate threaded to the outer surface of the threaded rod, a frame connected to the outer surface of the threaded plate, a plastic bottle body disposed inside the frame, a rectangular groove formed on the upper surface of the base plate, a sterilization chamber connected to the inner wall of the rectangular groove, a water outlet fixedly connected to the outer surface of the sterilization chamber, a drying chamber connected to the inner wall of the rectangular groove, and an air outlet fixedly connected to one end of the drying chamber.
[0006] Preferably, the upper surface of the long plate is provided with a groove, and the outer surface of the threaded plate is connected to a concave plate, wherein the outer surface of the concave plate is slidably connected to the inner wall of the groove.
[0007] Preferably, a telescopic rod is connected to the outer surface of the frame, a fixed plate is connected to one end of the telescopic rod, the outer surface of the fixed plate is slidably connected to the outer surface of the plastic bottle body, a spring is sleeved on the outside of the telescopic rod, one end of the spring is connected to the outer surface of the frame, and the other end of the spring is connected to the outer surface of the fixed plate.
[0008] Preferably, a conical barrel is fixedly connected to the inner wall of the rectangular groove, and a sewage outlet is fixedly connected to one end of the conical barrel.
[0009] Preferably, a vertical plate is connected to the bottom surface of the base plate, and a collection box is slidably connected to the outer surface of the vertical plate.
[0010] Preferably, a support rod is connected to the bottom surface of the base plate, and a pad is connected to the bottom end of the support rod.
[0011] Preferably, there are four vertical plates, arranged in pairs and symmetrically distributed.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This sterilization device for plastic bottle processing works by coordinating a motor, threaded rod, threaded plate, plastic bottle body, sterilization chamber, and drying chamber. When using the device, the plastic bottle body is secured to the outer surface of a fixed plate. When the bottle body moves below the outlet, the outlet sprays sterilizing water directly onto the bottle opening, sterilizing the inside of the bottle. When the bottle moves below the drying chamber, the drying chamber blows air to dry the bottle. This solves the problem that existing food-grade plastic bottles require sterilization before food storage, and sterilization personnel must manually perform the sterilization process. During sterilization, prolonged contact with the sterilizing water can corrode workers' hands and cause harm.
[0014] 2. This sterilization device for plastic bottle processing works by coordinating a motor, a rotating rod, a threaded plate, a fixed plate, a telescopic rod, and a spring. When using this device, the plastic bottle to be sterilized is clamped onto the outer surface of the fixed plate. The spring is compressed, and the telescopic rod is shortened, causing the fixed plate to press against the plastic bottle body and fix it in place. The output shaft of the motor drives the threaded rod to rotate via the rotating rod, and the threaded rod drives the threaded plate to move, so that several plastic bottles are sterilized and dried in sequence.

The pad 24 is made of rubber, which can increase the friction between the pad and the ground, making the device more stable.
[0023] There are four vertical plates 21, arranged in pairs symmetrically. The bottom surface of the vertical plates 21 has grooves that can hold the outer surface of the collection box 22 in place. The upper surface of the base plate 1 is connected to a long plate 2, and the outer surface of the long plate 2 is connected to a motor 3. The output shaft of the motor 3 is connected to a rotating rod 4, which drives the rotating rod 4 to rotate, providing power for the rotating rod 4 and facilitating operation.
[0024] One end of the rotating rod 4 is connected to a threaded rod 5. The outer surface of the threaded rod 5 is threaded with a threaded plate 6. When the threaded rod 5 rotates, it can drive the threaded plate 6 to move. The upper surface of the long plate 2 is provided with a groove 14. The outer surface of the threaded plate 6 is connected to a concave plate 15. The outer surface of the concave plate 15 is slidably connected to the inner wall of the groove 14. When the threaded rod 5 drives the threaded plate 6 to move, the concave plate 15 slides on the inner wall of the groove 14, limiting the movement of the threaded plate 6.
[0025] A frame 7 is connected to the outer surface of the threaded plate 6. A plastic bottle body 8 is set inside the frame 7. A telescopic rod 16 is connected to the outer surface of the frame 7. A fixing plate 17 is connected to one end of the telescopic rod 16. The outer surface of the fixing plate 17 is slidably connected to the outer surface of the plastic bottle body 8. A spring 18 is sleeved on the outside of the telescopic rod 16. One end of the spring 18 is connected to the outer surface of the frame 7, and the other end of the spring 18 is connected to the outer surface of the fixing plate 17. When the plastic bottle body 8 to be sterilized is clamped on the outer surface of the fixing plate 17, the spring 18 will be compressed, the telescopic rod 16 will be shortened, and the fixing plate 17 will squeeze the plastic bottle body 8 to fix the plastic bottle body 8. A rectangular groove 9 is opened on the upper surface of the base plate 1.
[0026] A conical barrel 19 is fixedly connected to the inner wall of a rectangular trough 9. One end of the conical barrel 19 is fixedly connected to a sewage outlet 20.

A water pump is installed inside the disinfection box 10, which can spray disinfectant water from the water outlet 11. A drying box 12 is connected to the inner wall of the rectangular trough 9. One end of the drying box 12 is fixedly connected to an air outlet 13.
[0027] The motor 3 and telescopic rod 16 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures. They can also be replaced by other power sources.
[0028] In use, the following steps are taken: the plastic bottle body 8 to be disinfected is clamped onto the outer surface of the fixing plate 17. The spring 18 is compressed, and the telescopic rod 16 is shortened, causing the fixing plate 17 to squeeze the plastic bottle body 8 and fix it in place. The motor 3 is started, and the output shaft of the motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the threaded plate 6 to move. At this time, the concave plate 15 slides on the inner wall of the groove 14, and the threaded plate 6 drives the frame 7 to move, so that several plastic bottle bodies 8 pass through the disinfection box 10 and the drying box 12 in sequence. When the plastic bottle body 8 moves to the bottom of the disinfection box 10, the water outlet 11 will spray disinfectant water onto the bottle mouth of the plastic bottle body 8 to disinfect the inside of the plastic bottle body 8. When the plastic bottle body 8 moves to the bottom of the drying box 12, the air blown out of the drying box 12 will dry the plastic bottle body 8. Excess disinfectant water will flow into the conical barrel 19 and out from the sewage outlet 20 to the inside of the collection box 22 for storage.
