Description

Technical Field

[0001] The utility model relates to the technical field of waste cleaning equipment, in particular to a full-automatic ejector waste cleaning equipment. Background Art

[0002] The cleaning of waste edges of printed products in the printing and packaging industries is called waste stripping, which is a necessary procedure for the trimming and forming processes of printed products. The emergence of waste stripping machines has replaced manual hammer waste stripping, which not only reduces labor intensity but also improves work efficiency.

[0003] In the current waste stripping machines for printed products, most of them require workers to manually place the printed products into the waste stripping machines, separate the printed products from the waste edges through ejectors, and after separation, workers need to manually take out the separated printed products and put them back into the printed products to be stripped. This method greatly reduces the work efficiency. The existing printed products have a thickness of 0.2-0.3mm, and in actual production, in order to save costs, generally only 2-3mm of waste edges are reserved after die-cutting of printed products. For the waste edges of this size, ejectors of corresponding sizes are required. However, since the outer diameter of the ejector is too thin, its strength is greatly reduced. If the printed products to be stripped are If the number is too large, the ejector pin will easily deform when lifting the printed product, and the ejector pin will need to exert greater force to eject all the waste edges when cleaning a large number of printed products, which will cause indentations on the upper and lower surfaces of the printed products and affect product quality. If the number of printed products to be cleaned is reduced, although the load on the ejector pin can be reduced, the frequency of paper feeding by the staff will be greatly increased, thereby reducing the cleaning efficiency and the labor intensity of the staff. In addition, since the thickness of the printed product is very small, the edge of the printed product will be deformed when the printed product is lifted by the ejector pin, resulting in the upper ejector pin being unable to press down the waste edge of the printed product, thereby affecting the cleaning work of the printed product.

[0042] In this embodiment, the distance between the paper supporting arms 411 is slightly larger than the outer diameters of the upper and lower ejector pins, so that when the paper receiving tray 41 enters the waste clearing conveyor belt 1, the paper receiving tray 41 can avoid the upper and lower ejector pins to prevent the paper receiving tray 41 from colliding with them and affecting the paper receiving work.

[0043] In this embodiment, the structure of the paper receiving bracket 9 is the same as that of the paper stack bracket 5, which will not be repeated here, so that the lower paper conveyor belt 46 can send the printed products with the waste edges removed into the paper receiving bracket 9 for stacking, thereby realizing automatic paper collection and stacking of printed products, reducing the labor intensity of the staff and greatly improving work efficiency.

[0044] In addition, in the present embodiment, a waste frame is placed below the waste stripping conveyor belt 1 and the lower paper conveying mechanism 4 to receive the waste edges sent out by the waste stripping conveyor belt 1, and the height of the paper receiving tray 41 in the present embodiment is slightly higher than the waste stripping conveyor belt 1, so that a waste stripping gap is formed between the end of the waste stripping conveyor belt 1 and the paper receiving tray 41, so that the waste edges fall into the waste frame from the waste stripping gap under the transmission of the waste stripping conveyor belt 1.

[0045] Reference Figure 4-Figure 7As shown, during specific operation, when the lower ejector lifts up the printed product and separates it from the waste edge, a gap is formed between the printed product and the waste edge, and the paper receiving drive device drives the paper receiving slide 45 to move toward the direction of the waste stripping conveyor belt 1, so that the plurality of paper supporting arms 411 on the paper receiving tray 41 extend into the gap between the printed product and the waste edge, and at the same time, the gap between the plurality of paper supporting arms 411 avoids the upper ejector and the lower ejector, and then the upper ejector and the lower ejector are reset, so that the plurality of paper supporting arms 411 support the printed product, while the waste edge remains on the waste stripping conveyor belt 1, and then the paper receiving drive device drives the paper receiving slide 45 to move toward the direction of the paper receiving bracket 9, and at the same time, the rotary drive device drives the waste stripping conveyor belt 1 forward toward the end direction, and the waste edge is sent into the waste frame under the transmission of the waste stripping conveyor belt 1, and the unloading drive device links the conveying bar 42 to rotate and send the printed product after the waste edge is removed to the lower paper conveyor belt, so that the lower paper conveyor belt sends the printed product to the paper receiving bracket 9 for stacking.

In this embodiment, the flipping drive device 441 preferably adopts a cylinder, and its telescopic end is hinged to the unloading rotating frame 44. Each time a different printed product is replaced, the upper ejector of the upper ejector mechanism 2 and the lower ejector of the lower ejector mechanism need to be rearranged. Therefore, the unloading rotating frame 44 is driven to flip upward by the flipping drive device, so that a pedestrian passage is formed between the waste conveyor belt 1 and the unloading paper support 43, providing space for the staff to adjust the upper ejector.
