Description

Technical Field

[0001] The utility model relates to an automatic coil material feeding device. Background Art

[0002] The seedling tray is an indispensable component of the rice transplanter, and its main function is to realize the rice seedling raising process. The seedling tray is made of polyvinyl chloride (PVC) and is formed by compression molding of the seedling tray compression molding machine. The polyvinyl chloride raw material for producing the seedling tray is generally a coil. Before the compression molding process, the PVC coil needs to be manually lifted to the feeding end of the seedling tray compression molding machine, but a roll of PVC coil is very heavy, and at least two adult male workers are required to lift it, which wastes labor; and when lifting and placing the coil, improper operation can easily pinch the hands, posing a hidden danger to the safety of the staff; in the case of insufficient manpower, only PVC coils with smaller diameters can be lifted, but due to the fast compression molding speed and large demand, new coils need to be replaced frequently, and replacing the coils will result in the production of seedling trays with many joints and incompleteness, resulting in an increase in waste trays and a waste of cost. Therefore, it is hoped to provide an automatic coil feeding device for a seedling tray compression molding machine. Summary of the invention
