Description

Technical Field

[0001] This utility model relates to the field of plastic bottle processing technology, and in particular to a flattening device for processing packaging plastic bottles. Background Technology

[0002] Plastic bottles are primarily made from materials such as polyethylene or polypropylene with the addition of various organic solvents. They widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded using plastic molds through blow molding, extrusion blow molding, or injection molding to create plastic containers. They are mainly used for single-use plastic packaging of liquids or solids such as beverages, food, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles are characterized by their durability, low cost, high transparency, and use of food-grade materials. However, plastic bottles require recycling after use.

[0003] Existing plastic bottle flattening devices first puncture the plastic bottle with a steel needle to allow the remaining liquid and gas inside to flow out, and then flatten the plastic bottle with a squeezing roller to reduce the volume occupied by the plastic bottle. However, even after puncturing the plastic bottle with a steel needle, residual liquid still accumulates inside the plastic bottle and splashes inside the device as it is flattened by the squeezing roller, affecting the service life of the device and making it difficult to squeeze and collect the plastic bottle. Therefore, a flattening device for processing packaged plastic bottles is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where residual liquid still accumulates inside plastic bottles even after piercing them with steel needles. This residual liquid then splashes inside the device as it is flattened by the compression rollers, affecting the device's lifespan and making it difficult to collect the plastic bottles. Therefore, this invention proposes a flattening device for processing plastic bottles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flattening device for processing plastic packaging bottles includes a flattening box. A drive motor is fixedly installed on one outer wall of the flattening box. A drive gear is fixedly connected to the output end of the drive motor. A driven gear meshes with the outer surface of the drive gear. A rotating shaft is fixedly connected to the outer wall of the drive gear and the driven gear away from the drive motor. Multiple cutting blades are fixedly connected to the outer surface of the rotating shaft. A first rotating wheel is fixedly connected to the outer wall of the rotating shaft. A second rotating wheel is rotatably connected to the outer surface of the first rotating wheel via a track. A rotating rod is fixedly connected to the outer wall of the second rotating wheel. An eccentric wheel is fixedly connected to the top of the rotating rod. A filter plate abuts against the upper surface of the eccentric wheel. Two telescopic rods are fixedly connected to the lower surface of the filter plate. A return spring is sleeved on the outer surface of the two telescopic rods. A support plate is fixedly connected to the bottom of the two telescopic rods. A partition is provided at the end of the filter plate away from the eccentric wheel. A baffle is slidably connected to the outer wall of the partition. A toothed plate is fixedly connected to the top of the baffle. A transmission gear meshes on the outer surface of the toothed plate. A shaft is fixedly connected to the outer wall of the transmission gear. A servo motor is fixedly connected to the outer wall of one end of the shaft. When the eccentric wheel rotates to the lowest point, the filter plate falls back under the action of the return spring. The telescopic rods provide guidance to prevent the filter plate from moving laterally. This continuous "lift-fall" process causes the filter plate to vibrate at high frequency.

[0006] Furthermore, a hydraulic cylinder is fixedly installed on the top of the flattening box, and an extrusion plate is fixedly connected to the output end of the hydraulic cylinder. The hydraulic cylinder provides strong downward pressure, driving the extrusion plate to move downward, pressing the cut and collected plastic bottles into compact cakes, greatly reducing the volume.

[0007] Furthermore, a recycling bin is provided on the side of the partition away from the filter plate, and the recycling bin is located directly below the extrusion plate.

[0008] Furthermore, a discharge groove is provided on the outer surface of the partition, and the covering area of ​​the baffle is larger than the discharge groove. The partition has a discharge groove for the bottle flakes to pass through, and the size of the baffle is sufficient to completely cover the discharge groove, ensuring that the plastic bottle will not leak when closed.

[0009] Furthermore, a feed hopper is fixedly connected to the top of the flattened box at the end away from the hydraulic cylinder, a waste liquid tank is fixedly connected to the bottom wall inside the flattened box, and a drain pipe is fixedly connected to the outer wall of one side of the waste liquid tank.

[0010] Furthermore, the end of the drain pipe away from the waste liquid tank passes through the flattened box body and extends to the outside, and the waste liquid tank is located directly below the filter plate.

[0011] Furthermore, a through groove is provided on the upper surface of the flattened box body. The through groove is located directly above the toothed plate. The through groove on the flattened box body provides space for the up and down movement of the toothed plate. This is a mechanical design to ensure the normal operation of the baffle and to avoid motion interference when the toothed plate rises.

[0012] Furthermore, a controller is provided on the front of the flattened box, and the drive motor, servo motor and hydraulic cylinder are all electrically connected to the controller.

[0013] This utility model has the following beneficial effects: In this application, a drive motor, a driving gear, a driven gear, a rotating shaft, and a cutting blade are used to cut the recycled plastic bottles. Compared to piercing the bottles with a steel needle to drain the liquid, the cut is larger, allowing the liquid to drain faster and more easily. The first rotating wheel, the second rotating wheel, the rotating rod, the eccentric wheel, the telescopic rod, and the return spring work together to separate the liquid from the plastic bottles using a filter plate. The filter plate also vibrates up and down to accelerate the drainage of the liquid from the bottles, ensuring that the liquid is fully discharged and preventing residual liquid from being squeezed out, which could contaminate the equipment and make subsequent collection and processing difficult.

[0020] A discharge trough is provided on the outer surface of the partition 15, and the covering area of ​​the baffle 16 is larger than that of the discharge trough.

[0021] A feed hopper 24 is fixedly connected to the top of the flattened box 1 away from the hydraulic cylinder 21. A waste liquid tank 25 is fixedly connected to the bottom wall inside the flattened box 1. A drain pipe 26 is fixedly connected to the outer wall of one side of the waste liquid tank 25.

[0022] The drain pipe 26 extends through the flattened box 1 and outwards from the end away from the waste liquid tank 25. The waste liquid tank 25 is located directly below the filter plate 11.
