Provided is a plate material feeding device that can achieve reduced power consumption, improve durability, and supply plate material with high precision. A plate material feeding device is provided with a housing, a lower roll, an upper roll, a lower roll support member for supporting the lower roll, an upper roll support member for supporting the upper roll, and a slider movable in the horizontal direction along the upper roll support member, and can feed plate material clamped by the lower roll and the upper roll. A hole is provided in the slider, and a rod is provided in the upper roll support member. By inserting at least part of the rod in the hole in a slidable manner, the upper roll support member can move in the vertical direction when the slider moves in the horizontal direction.

The present invention refers to an apparatus and a method for wrapping a film around an object. The apparatus includes a device capable of being electrostatically charged and capable of transmitting the electrostatic charge to the portion of film that comes out of the carriage. In this way, the fixing of the leading end flap of the film around the object to be wrapped is thus facilitated. In fact, the leading end flap of the film, as soon as it is dispensed, remains stretched out of the carriage and, as soon as it meets the object to be wrapped, it immediately fastens to it due to the attraction force. The rotation is then activated to wrap the film around the object. The apparatus is simple to make, cheap, and highly efficient.

A transporting apparatus includes a pressurizing roller that transports a web-like or sheet-like transport target object and a heating roller disposed downstream of the pressurizing roller in a transport path, a first bottom sensor and a first top sensor that are disposed between the pressurizing roller and the heating roller, a measuring section that measures a time from when the transport target object is detected by the first bottom sensor until the transport target object is detected by the first top sensor, and a rotation control section that modifies a rotation speed of the heating roller when a time measured by the measuring section is shorter than a first reference time.

The present invention relates to the technical field of optical film production, and provides a light guide film production device, including a feeding unit, a fusion stirring unit, an extrusion molding unit, a cooling shaping unit, a guide leveling unit, a flattening unit, and a finished product winding unit. The cooling shaping unit is provided with a first water tank to perform heat exchange on an extruded light guide film for heat recovery, so that edge film pressing mechanisms press pressure blocks at the edge film positions using the memory effect of a memory alloy. Circulating water of the first water tank subjected to heat exchange is delivered to a second water tank disposed in the flattening unit, so that a first conveyor belt made of the memory alloy in a third drive device drives a second rolling roller set to rotate to realize secondary utilization of recovered heat. In the present invention, an air delivery mechanism with one airflow pipe to the cooling shaping unit, and the other airflow pipe to the flattening unit is further provided. According to the present invention, the heat of the light guide film production process is used to improve the quality of the light guide film and reduce the energy consumption of the light guide film production process.
