Abstract

The invention relates to a rolling testing machine for a mould-pressed tray and a testing method, in particular, a rolling testing machine for the corner impact strength testing of a mould-pressed tray and a testing method. The testing machine is provided with corresponding mechanisms for implementing the rolling detection items of mould-pressed products, and has the advantages of structural simplicity and convenience in operation. The method has the advantages of concise steps and high pertinence in testing items. According to the technical schemes, the rolling testing machine for the cornerimpact strength testing of the mould-pressed tray comprises a vertical rack and a controller. The rolling testing machine is characterized in that the rack is provided with a test box capable of containing the mold-pressed tray and rotating around a horizontal axis and a power mechanism for driving the test box to rotate; the test box is a cylindrical box body with a horizontally-distributed axis;the test box is rotationally positioned at the upper part of the rack through a horizontally-arranged rotating shaft which is driven by a motor; a pair of supporting rollers support two sides of thesuspended lower part of the test box so as to keep the stability of the rotation of the test box.

Description

technical field [0001] The invention relates to a testing device and a testing method for the angular impact strength of a molded product, in particular to a rolling testing machine and a testing method for testing the angular impact strength of a molded pallet. Background technique [0002] Pallet is one of the two major components of modern logistics in the world today. It is a vehicle for loading, unloading and transporting modern logistics goods. Compared with traditional goods, pallets have the advantages of high work efficiency, lower logistics costs, and safe and convenient transportation. Pallets stack scattered goods and together with containers form a container unit transportation system, which has become the main part of the modern logistics system. [0003] Wood is the earliest material used to make pallets. It occupies a dominant position in the pallet market because of its convenient material acquisition, simple manufacturing process, and low production cost. H...
