Description

Technical Field

[0001] The utility model relates to the technical field of packaging production equipment, in particular to a lifting hole cleaning device for carton processing. Background Art

[0002] During the packaging process, punching holes in the cardboard is often necessary to improve airflow inside and outside the box. This is especially true for fruit and vegetable packaging, which requires a high number of holes for heat dissipation and ventilation. This can lead to paper scraps becoming lodged in the holes, requiring a waste removal device to remove them. Because packaging boxes for different products vary in shape and size, the placement and number of holes also vary, requiring a waste removal device that can be adjusted to improve waste removal efficiency.

[0003] For example, Chinese patent application CN202122975324.5 describes a device for cleaning waste from the inner holes of a packaging box that is easy to adjust, including a workbench and a hole cleaning mechanism. The workbench is in a grid shape with upper and lower surfaces connected. The hole cleaning mechanism includes a pressure plate, a lifting mechanism, and a bracket. The pressure plate is parallel to the upper surface of the workbench. The bracket is fixedly installed on the assembly line. The lifting mechanism is installed on the bracket. The lifting mechanism is used to make the pressure plate move up and down. A number of small holes and ejector pins are provided on the pressure plate. The small holes are opposite to the grid on the workbench. The ejector pin is installed in the small hole. The lower end of the ejector pin extends out of the small hole. The ejector pin is detachably connected to the small hole.

[0004] However, in the prior art, the grid structure on the workbench of the hole cleaning device is fixed, and it is difficult for paper pieces in some punched holes of different shapes to fall through the grid; therefore, for different punched hole structures, the space on the workbench cannot be flexibly adjusted, resulting in a problem of limited scope of use. In addition, in the process of hole cleaning, in order to improve efficiency, multiple packaging cardboards are often stacked together, and then the pressure plate is lowered, and the ejector pins are used to pass through multiple cardboards at the same time, so that the waste pieces in the same hole position fall out. Since the packaging cardboard is generally covered with an oil film for waterproof and oil-proof purposes, it is time-consuming to manually align the multiple layers of packaging cardboard after stacking them together. In addition, the downward pressing action of the pressure plate may still cause the stacked cardboards to be misaligned, causing the ejector pins to push into the wrong position, resulting in damage and defective products. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the grid structure on the workbench of the hole cleaning device is fixed, and it is difficult for some paper pieces in the punched holes of different shapes to fall through the grid; therefore, for different punched hole structures, the spaces on the workbench cannot be flexibly adjusted, resulting in a limited scope of use. A lifting hole cleaning device for carton processing is provided.

[0006] The purpose of the utility model is achieved through the following technical solutions: A lifting hole-cleaning device for carton processing, comprising a workbench and a support frame; a blanking channel is provided on the workbench; support parts are provided at intervals on the blanking channel; both ends of the support parts are detachably connected to the workbench on both sides of the blanking channel; cardboard is placed on the support part; a lifting mechanism is provided on the support frame; a pressing plate is connected to the lifting mechanism; a hole-cleaning member is provided on the pressing plate; the hole-cleaning member is used to poke out paper pieces in holes on cardboard; an alignment mechanism is also provided on the support frame; the alignment mechanism is used to align and sort stacked cardboards;

[0007] Furthermore, the workbench is a rectangular frame; adjustment slots are provided on both sides of the workbench; mounting holes are provided at both ends of the support portion corresponding to the adjustment slots; fixing pieces are provided in the mounting holes;

[0008] Furthermore, the alignment mechanism includes an alignment plate, a connecting block and an adjustment rod; one side of the alignment plate is connected to the adjustment rod through the connecting block; the adjustment rod is connected to the support frame; the adjustment rod is used to adjust the distance between the alignment plate and the edge of the workbench;

[0009] Furthermore, the support frame includes side panels, a back panel, and a top panel; the adjustment rod is connected to the back panel; the adjustment rod is a screw rod and the adjustment rod passes through the back panel and is fixed to the back panel by a nut;

[0010] Furthermore, the hole cleaning member includes a hole cleaning rod and an adjusting block; one end of the hole cleaning rod is connected to the pressure plate through the adjusting block; the other end of the hole cleaning rod is provided with a waste cleaning head;

[0011] A further technical solution is that a waist-shaped groove is further provided on the adjusting block; the hole cleaning rod is a screw rod and the hole cleaning rod passes through the waist-shaped groove and is fixed on the adjusting block by a nut.

[0012] The utility model has the following advantages:

[0013] 1. Support parts are arranged at intervals on the blanking channel of the workbench, which can facilitate the placement of multiple cardboards on the support parts. At the same time, the gap formed between two adjacent support parts can facilitate the waste paper pieces in the holes to fall and fall to the bottom of the workbench for collection. Since the support parts are detachable and arranged on the workbench, they can be adjusted according to the size and position of the holes, which has strong flexibility and can adapt to different cardboards. At the same time, the operation is simple and convenient, and the modification cost is low.

[0014] 2. An alignment mechanism is set on the support frame. When cleaning holes in multiple layers of cardboard, the edge of one side of the stacked cardboard is pushed to align with the alignment mechanism to ensure that the holes of multiple cardboards are located on the same axis, avoiding the hole cleaning mechanism from accidentally damaging other areas and causing damage to the cardboard.
