Description

Technical Field

[0001] This utility model belongs to the field of packaging and printing technology, and specifically relates to waste collection equipment for packaging and printing. Background Technology

[0002] Packaging printing is printing on various packaging materials. A lot of waste is generated during the packaging printing process. Some of the packaging printing waste can be reused after collection, such as waste paper. Therefore, waste collection equipment is needed to collect and process the packaging printing waste.

[0003] Chinese patent CN221934990U discloses a waste collection device for packaging and printing, including a collection box. A collection compartment is installed at the bottom of the collection box, and casters are fixedly connected to both sides of the bottom. Support frames are fixedly connected to both sides of the top of the collection box, and a crushing box is installed on one side of the support frame. An inlet is installed at the top of the crushing box, and a first crushing roller and a second crushing roller are movably installed inside the crushing box. An inlet pipe is fixedly connected to the bottom of the crushing box, and a hydraulic cylinder is installed at the top of the collection box. This waste collection device uses the hydraulic cylinder to push a compression plate downwards, compressing the waste material. The compression plate compacts the waste material inside the collection box for collection. During the compression process, ball bearings improve the stability of the compression. This structure facilitates the centralized collection of waste, improves collection efficiency, and solves the problem of difficult centralized collection.

[0004] However, when the aforementioned patent crushes and compresses waste paper scraps, the scraps are small and lightweight, resulting in insufficient compression and easy loosening, causing paper scraps to scatter in the workshop. Therefore, a waste collection device for packaging and printing is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the problems in the existing technology where paper scraps are small and lightweight, have insufficient compression, and are prone to loosening, causing paper scraps to scatter in the workshop. This invention provides a waste collection device for packaging and printing that uses nozzles in the collection chamber to spray water on the paper scraps, followed by compression. The water increases the adhesion between the paper scraps, ensuring their compactness and preventing them from scattering.

[0006] To achieve the above objectives, this utility model provides a waste collection device for packaging and printing, including a collection bin, a waste drawer movable at the lower end of the collection bin, a hydraulic press mounted on the upper wall of the collection bin, a pressure plate mounted below the hydraulic press, the pressure plate positioned above the waste drawer, the hydraulic press controlling the pressure plate to press the waste onto the waste drawer, a water pump mounted on the inner wall side of the collection bin, a nozzle connected to the water pump facing the waste drawer, a liquid extraction pipe mounted at the lower end of the water pump, the liquid extraction pipe drawing liquid from the bottom of the collection bin, and the water pump spraying the liquid onto the waste on the waste drawer through the nozzle.

[0007] Preferably, baffle filter plates are symmetrically arranged on both sides of the inner wall of the collection chamber. The baffle filter plates are located on both sides of the waste drawer and are used to filter and separate liquid and waste.

[0008] Preferably, the upper end of the collection bin is provided with a crushing bin, the crushing bin includes an upper guide plate, a crushing roller, a crushing bin body and a lower guide plate, the crushing bin body is embedded in the upper end of the collection bin and connected to the collection bin, the crushing roller is provided in the crushing bin body, the upper guide plate is symmetrically arranged at the upper end of the crushing bin body, the lower guide plate is symmetrically arranged at the lower end of the crushing bin body, and the upper guide plate and the lower guide plate are respectively located above and below the crushing roller.

[0009] Preferably, a side guide plate is provided on the side of the collection chamber near the crushing chamber, the upper end of the side guide plate is located below the crushing chamber, and the side guide plate is located on one side of the pressure plate.

[0010] Preferably, a tray is provided at the lower end of the side of the collection chamber near the crushing chamber. The tray is located above the baffle filter plate and below the side guide plate, and the tray is inclined toward the waste drawer.

[0011] Preferably, the waste drawer includes an outer panel, a groove, a bottom panel, and an inner panel. The bottom panel is movable within the collection chamber. The two sides of the bottom panel are inclined downwards to facilitate liquid flow. The bottom surface of the pressure plate corresponds to the top shape of the bottom panel. The inner panel and the outer panel are symmetrically arranged on both sides of the bottom panel. The groove is embedded in the outer surface of the outer panel.

[0012] Preferably, a buffer rod is provided between the hydraulic press and the pressure plate.

[0013] Preferably, the buffer rod includes a buffer chamber, a connecting rod, a spring, and a limiting tube. Two sets of buffer chambers are symmetrically arranged. The buffer chambers are respectively located on the pressure plate and under the hydraulic press. The spring is located inside the buffer chamber. The upper and lower sections of the connecting rod are respectively inserted into the two sets of buffer chambers and fixedly connected to the spring. The limiting tube is located inside the buffer chamber and is movably sleeved on the connecting rod.

[0014] Preferably, the bottom wall of the collection chamber is provided with a lifting block, which is located directly below the liquid extraction pipe. The lifting block is higher than the bottom of the collection chamber, and the paper scraps sink into the liquid. It is difficult for the paper scraps to move onto the lifting block. Therefore, the lifting block can prevent the paper scraps from being pumped in by the water pump.

[0015] The beneficial effects of this utility model are:

[0016] This invention features a nozzle installed in the collection chamber to spray water onto the paper scraps, which are then compressed. The water increases the adhesion between the paper scraps, ensuring their compactness and preventing them from scattering. This solves the problem in the prior art where the paper scraps are small and lightweight, resulting in insufficient compression and easy loosening, causing paper scraps to scatter in the workshop.
