Description

Technical Field

[0001] The utility model relates to the technical field of plastic pallet cutting equipment, in particular to an online cutting device for a plastic electronic pallet. Background Art

[0002] Plastic pallets are a medium that transforms static goods into dynamic goods. They are a cargo platform and a movable platform. Once loaded on the pallet, it immediately becomes mobile and becomes a flexible mobile cargo, because the goods loaded on the pallet are ready to move at any time. In the production and processing of electronic materials, it plays an important role in the transportation of electronic components and materials.

[0003] After the processing of plastic electronic pallets is completed, in order to make the subsequent use of plastic pallets more convenient, the excess plastic burrs on the outside of the pallets are often cut off. However, after cutting, the edges of some plastic pallets are relatively sharp, which can easily scratch the hands of workers when carrying pallets, posing certain safety hazards. When the workers are already injured, processing the edges of the pallets not only causes harm to the workers, but also indirectly slows down the production efficiency of subsequent plastic electronic pallets. Therefore, we propose to design an online cutting device for plastic electronic pallets. Utility Model Content

[0031] A cutting mechanism 7 is provided on the top of the fixing plate 5 .

[0032] The cutting mechanism 7 includes a linear motor 701 fixedly connected to the top of the fixed plate 5, the driving end of the linear motor 701 is fixedly connected to the equipment frame 702, the top of the equipment frame 702 is fixedly connected to a second motor 703, the driving shaft of the second motor 703 passes through the equipment frame 702 and is provided with a grinding head 704, the side wall of the equipment frame 702 is fixedly connected to a tool holder 705, and a cutting head 706 is provided inside the tool holder 705.

[0033] In this embodiment, the end of the driving shaft of the second motor 703 is fixedly connected to a mounting seat corresponding to the grinding head 704. The grinding head 704 is detachable to facilitate maintenance and replacement of the grinding head 704. The bottom of the grinding head 704 is conical and the inclined outer surface is convenient for grinding and polishing the edge of the plastic pallet after cutting the burrs.

[0034] A support assembly 8 is provided at the top center of the positioning frame 2 .

[0035] The support assembly 8 includes a base 801 fixed at the top center of the positioning frame 2, an electric push rod 802 is fixedly connected to the bottom center of the base 801, the telescopic end of the electric push rod 802 passes through the base 801 and is fixedly connected to the lifting platform 803, and the plastic pallet is placed on the top of the lifting platform 803. By starting the electric push rod 802 to drive the driving end to telescope, the height of the plastic pallet can be adjusted so that its edge can correspond to the cutting head 706 and the grinding head 704.

When moving, the cutting head 706 is always kept moving in front of the grinding head 704. After the cutting head 706 removes the burrs, the grinding head 704 then grinds the edge of the plastic pallet to make the edge smoother and no longer sharp.

[0042] The device can cut two sides of the plastic pallet simultaneously. After a single operation is completed, the first motor 3 drives the clamping plate 602 to move and loosen. The staff can rotate the plastic pallet 90 degrees and then clamp it with the clamping plate 602 to cut the remaining sides. Most of the waste generated during cutting can fall into the collection tank 1 under the blockage of the guard plate 101, which is convenient for subsequent opening of the movable door 102 for unified cleaning.
