Description

Technical Field

[0001] This utility model relates to the field of cardboard box punching technology, specifically a punching device for cardboard box processing. Background Technology

[0002] In the cardboard box processing flow, the punching process is crucial, directly affecting core functions such as bundling and securing during subsequent sealing, and ventilation and moisture protection during warehousing and transportation. Its processing quality and efficiency have a significant impact on the overall production chain. Currently, most mainstream cardboard box punching devices on the market suffer from insufficient operational continuity, with most relying on manual assistance for the entire loading and unloading process: workers must place the cardboard boxes to be processed one by one to the designated workstation, punch them, and then manually transfer them to the unloading area. This results in significant pauses between the processing of two sets of cardboard boxes, making it impossible to achieve seamless integration of the entire process of conveying, positioning, punching, and unloading. The processing capacity per unit time is limited, making it difficult to meet the high-efficiency requirements of modern large-scale production.

[0003] Meanwhile, the existing equipment has significant shortcomings in adaptability. Its punching mechanism is mostly a fixed installation design, and the punching position is relatively fixed. When production needs to switch to different models and sizes of cartons, and it is necessary to adjust the horizontal spacing or vertical position of the punching, the fixed components of the punching mechanism must be disassembled first. After repeated measurement and calibration, it must be reinstalled and debugged. This process is not only cumbersome and time-consuming, but also difficult to control the accuracy of manual debugging, which can easily lead to deviations in the punching position, resulting in a decrease in product qualification rate and an increase in production costs.

The movement of the limit frame can be controlled by the third electric push rod, and the movement of the guide rollers can be controlled by the limit frame. The guide rollers can limit the conveying of the carton to be punched, thereby improving the conveying accuracy during punching. To ensure guiding performance, the present invention can choose to cover the outside of the guide rollers with a conveyor belt to avoid the carton getting stuck during the conveying process.

[0011] The present invention is further configured such that a detection camera is provided on the mounting frame. The detection camera adopts an existing industrial camera, which can realize the surface detection and positioning of the carton to be punched. The detection camera is linked with the first electric push rod, the second electric push rod, the lead screw motor, etc. through the PLC control system, so that the position of the punch can be flexibly adjusted according to the model and size of the carton to be punched and the punching position.

[0012] The present invention is further configured such that a collection box is provided below the support platform. The collection box is located below the punch groove, and the waste material impacted by the punch can fall directly into the collection box below through the punch groove for collection, thus avoiding the waste material from scattering.

[0013] Compared with existing technologies, the beneficial effects of this utility model are: 1. Achieving continuous and efficient punching operations. This utility model uses a loading and unloading conveyor connected to a support platform, combined with a detection camera for positioning and guide rollers for limiting, ensuring precise carton delivery without interruption between loading and unloading.
