Description

Technical Field

[0001] The utility model relates to the technical field of plastic pallet processing, in particular to a punching device for plastic pallet processing. Background Art

[0002] Pallets, as crucial equipment for loading, unloading, storage, and transportation in logistics operations, play a significant role in modern logistics when used in conjunction with forklifts. The benefits they bring to the modern logistics industry are primarily reflected in: unitizing, normalizing, and standardizing item packaging, protecting items, and facilitating logistics and commercial flows. Pallets used in logistics come in a variety of types, depending on their material, purpose, surface, forklift access method, and structure. To increase the flexibility of plastic pallets, holes for tying ropes need to be drilled.

[0003] When the existing punching machine is in use, the plastic pallet is easily displaced due to the lack of a component to fix the pallet, resulting in inaccurate punching. At the same time, the waste generated by the punching is left on the operating table and is difficult to collect, affecting the punching operation.

[0004] A Chinese patent discloses a plastic pallet punching machine (authorization publication number CN220972621U). This patented technology can fix the plastic pallet placed on the operating table, preventing the plastic pallet from moving and causing inaccurate punching. The waste generated by punching the plastic pallet falls through the punching slot into a collection box placed in the bottom bin. The staff can pull out the collection box by pulling the handle, making it convenient to collect the waste generated by punching the plastic pallet, and avoiding the problem of waste remaining on the operating table and causing inconvenience in the punching operation.

[0005] However, it has certain disadvantages: although it can collect waste on the operating table, during the punching or other processing process, waste materials such as plastic debris or powder will remain inside the holes of the plastic pallet. These waste materials will gradually accumulate, and manual labor is required to regularly clean the waste on the pallet, which will increase additional labor costs and time costs and reduce production efficiency. Utility Model Content

[0006] The purpose of the utility model is to provide a punching device for processing plastic pallets to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A punching device for processing plastic pallets, comprising a punching table, wherein an opening is formed on the upper surface of the punching table, and a support base is fixedly connected to the upper surface of the punching table on the right side of the opening; a first telescopic cylinder is fixedly connected to the upper surface of the support base, a support plate is fixedly connected to the telescopic end of the first telescopic cylinder, and a plurality of cutting heads are fixedly connected to the lower surface of the support plate; and positioning mechanisms are provided at the four corners of the upper surface of the punching table near the opening;

[0009] A cleaning mechanism is provided on the upper surface of the punching table in front of the opening, and the cleaning mechanism includes a connecting plate, a fan is fixedly connected to the right end of the upper surface of the connecting plate, an air duct is fixedly connected to the air outlet end of the fan, a main pipe is fixedly connected to the left end of the air duct, and a plurality of branch pipes are fixedly connected to the lower surface of the main pipe. The cleaning mechanism also includes a rotating mechanism that drives the connecting plate to rotate.

[0011] As a further solution of the present invention: the rotating mechanism includes a connecting seat, the lower surface of the connecting seat is fixedly connected to the motor, and the upper surface of the connecting seat is rotatably connected to the connecting rod, and the output end of the motor and the outside of the connecting rod are both fixedly connected to gears.

[0012] As a further solution of the present invention: the support plate is opposite to the opening, and the branch pipe is connected to the connecting plate through it.

[0013] As a further solution of the present invention: the positioning seat is fixedly connected to the upper surface of the punching table.

[0014] As a further solution of the present invention: the connecting seat is fixedly connected to the upper surface of the punching table, the upper end of the connecting rod is fixedly connected to the right end of the lower surface of the connecting plate, and the two gears are meshed with each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model is provided with a positioning mechanism. The second telescopic cylinder in the positioning mechanism extends to drive the positioning plate to clamp and fix the plastic pallet, thereby avoiding deviation during punching.

[0017] 2. The utility model is provided with a cleaning mechanism. The fan in the cleaning mechanism draws air from the outside and sprays the airflow through the branch pipe. The motor drives the connecting rod to rotate through two gears, so that the connecting plate sweeps over the plastic pallet, so that the airflow blows off the residual waste in the holes of the plastic pallet, reducing the amount of residual waste and eliminating the need for long-term manual cleaning in the later stage.
