Description

Technical Field

[0001] The utility model relates to the technical field of wooden pallet production, in particular to a performance testing device for wooden pallet production. Background Art

[0002] Wooden pallets are pallets made of natural wood and are the most widely used pallets. Pallets are horizontal platform devices used for packaging, stacking, handling and transportation of goods and products as unit loads. They are generally made of wood, metal and fiberboard, and are convenient for loading and unloading, and for carrying unit materials and small quantities of materials. Wooden pallets are usually subject to random inspection after production and extrusion testing, so as to test the load-bearing capacity of wooden pallets to meet the standards for use. However, during use, existing performance testing devices usually place wooden pallets directly on the test bench and then perform extrusion testing. This not only makes the wooden pallets easy to deviate and shake during the test, affecting the test results, but also when the quality of the wooden pallets is unqualified, the extrusion will cause the wooden pallets to break. Due to the lack of corresponding protective structures, the broken wood blocks splash and can easily cause harm to the operator. Therefore, a performance testing device for wooden pallet production is proposed. Utility Model Content
