Technical Field
[0001] The utility model relates to the technical field of emery cloth transportation, in particular to an emery cloth transportation frame. Background Art
[0002] Emery cloth is made by bonding abrasives evenly to a solid cloth with a binder. It has excellent properties such as good wear resistance, high temperature resistance and strength. It is mainly used to grind rust, paint or burrs on the surface of workpieces and polish the surface. For this reason, emery cloth is a commonly used abrasive tool. The production of emery cloth adopts a linkage production line. The production process of emery cloth includes unwinding the cloth, laying the base flat and tensioning, applying primer, electrostatic sand planting, pre-drying, re-gluing, drying and curing, so as to prepare tough and wear-resistant emery cloth. The emery cloth material is then wound onto a sleeve rod to form an emery cloth roll that is easy to store, so as to facilitate the collection of the prepared emery cloth material. However, according to the requirements for the delivery of emery cloth, the emery cloth roll is processed by printing, striping, cutting, etc., so that the emery cloth is shaped into the corresponding size according to the requirements of specifications and uses.
[0003] The abrasive cloth production line produces tough and wear-resistant abrasive cloth. After being wound onto the sleeve rod to form the finished abrasive cloth roll, the abrasive cloth roll needs to be transferred to the transit warehouse for storage, or according to the abrasive cloth order, the abrasive cloth roll needs to be transferred to the abrasive cloth shaping equipment such as printing, striping, and cutting for shaping. In this process, the abrasive cloth roll needs to be transferred in the workshop using a transfer device. The abrasive cloth transfer device is composed of a pallet and a forklift. The finished abrasive cloth roll wound onto the sleeve rod is neatly placed on the pallet in sequence. The forklift's support arm is controlled to penetrate from the bottom of the pallet, and the forklift's support arm is controlled to rise, thereby lifting the pallet and the abrasive cloth roll placed on the pallet. Then, the forklift is controlled to move to the placement position, and the forklift's support arm is controlled to descend, so that the support arm and the pallet are separated, thus completing the transportation of the abrasive cloth roll. However, since the abrasive cloth roll has a cylindrical structure, in order to prevent the abrasive cloth from rolling off the pallet during transportation, only one layer of abrasive cloth roll is placed on the pallet. Although this method can reduce the occurrence of abrasive cloth rolling, it will also reduce the transportation efficiency of the abrasive cloth roll. Moreover, before the emery cloth roll is put into storage or transported to the shaping equipment, it is necessary to inspect and verify the relevant parameters of the emery cloth roll, such as the thickness of the emery cloth, the bonding effect of the abrasive, the polishing mesh of the emery cloth, etc. However, since the emery cloth roll is placed flat on the pallet, it is difficult to pull the emery cloth out of the flat emery cloth roll for inspection and verification. Therefore, the sleeve rod of the flat emery cloth roll needs to be rotated and set on the detection bracket so that the emery cloth can be pulled out from the emery cloth roll for inspection and verification, which undoubtedly increases the difficulty of emery cloth inspection and verification. Therefore, there are room for improvement in the carrying capacity, transportation inspection and verification of emery cloth transportation to facilitate the transportation of emery cloth.
