Description

Technical Field

[0001] The utility model relates to the technical field of PET bottle recycling equipment, in particular to a walking bottle collecting and weighing device used in the PET bottle recycling industry. Background Art

[0002] PET bottles are widely used in beverage packaging, food, chemical industry, medicine and other fields due to their light weight, non-toxicity, high transparency, good airtightness, impact resistance and resistance to breakage. When these PET bottles are discarded, they are faced with the problem of how to deal with them. In order to save resources and protect the environment, the discarded PET bottles need to be recycled and reused. Since my country's solid waste recycling system is not yet perfect, and discarded PET bottles have a certain economic value, households and scavengers will collect a certain amount of discarded PET bottles and sell them to waste recycling operators, who will then resell the discarded PET bottles to packaging stations. In this process, waste recycling operators will simply package the PET bottles provided by households and scavengers and price them by weight. When these discarded PET bottles are transported to the packaging station, in order to verify the items in the packaging, the packaging needs to be removed and re-weighed. Because households, scavengers, and waste recycling operators do not have professional compression and volume reduction equipment when recycling PET bottles, the discarded PET bottles still maintain their original round shape or a simple compressed shape after being stepped on. When the packing station checks the discarded PET bottles transferred by the waste recycling operators, the unpacked PET bottles are scattered on the ground inside the packing station. The staff of the packing station needs to spend a lot of time to complete the collection and weighing of the scattered PET bottles, and the work efficiency is low. Utility Model Content

After the PET bottles in the weighing chamber 17 of the weighing box 10 are emptied, the piston rods of the two opening and closing cylinders 12 are retracted at the same time, driving the opening and closing material blocking door 11 to flip inward and close the rear opening of the weighing box 10, and then the piston rod of the bottle unloading cylinder 18 is retracted, driving the push block 19 to move down to the bottom of the bottle unloading flap 14. At this time, the front end of the bottle unloading flap 14 will be pressed on the flap resting strip 13 again under the action of its own weight, thereby reclosing the bottom opening of the weighing box 10. At this time, the opening and closing material blocking door 11, the unloading flap 14, the flap resting strip 13 and the left and right side panels of the weighing box 10 will jointly constitute the weighing chamber 17 again, waiting for the next weighing.

[0019] The utility model has the advantages of simple operation, short time consumption, automatic collection and weighing of scattered PET bottles, and greatly improved work efficiency.
