Description

Technical Field

[0001] The utility model relates to the field of release film production, in particular to a precise feeding device for producing OPP release films. Background Art

[0002] Usually, in order to increase the release force of plastic film, the plastic film will be plasma treated, fluorine coated, or coated with silicone release agent on the surface of the film material, such as PET, PE, OPP, etc., so that it can show extremely light and stable release for various organic pressure-sensitive adhesives (such as hot melt adhesive, acrylic adhesive and rubber-based pressure-sensitive adhesive).

[0003] Release films are mostly coated as the substrate. After spraying, they are rolled up and stored. The existing device uses radial cutting along the direction perpendicular to the substrate. Since the release film is always in a conveying state, the cutting surface will be tilted during cutting, resulting in errors in the final rolled length, and the rolled length is not accurate enough.

[0016] The utility model has the following beneficial effects:

[0017] 1. A support plate is connected to the inner wall of the workbench, and a double-headed motor is connected to the top of the support plate. When the double-headed motor is running, the two output ends respectively drive the rotating shaft connected thereto to rotate, thereby causing the turntable connected to the rotating shaft to rotate accordingly, and the outer wall of the turntable is movably connected to the linkage plate, and the outer wall of the other side of the linkage plate is movably connected to the inner wall of the limit plate. During the rotation of the turntable, the bottom end of the linkage plate moves with the turntable. When the bottom end of the linkage plate rotates from the bottom end of the turntable to the upper end of the turntable, the limit block drives the cutter to move from bottom to top. When the top end of the cutter moves to the triangular groove opened at the bottom of the fixed plate, the substrate can be cut. At this time, the incision of the substrate is horizontal, the cutting interval is controlled, and the winding length of the final release film after forming is accurately controlled. The existing device adopts radial cutting along the direction perpendicular to the substrate. Since the release film is always in a conveying state, the cutting surface will be tilted during cutting, resulting in an error in the length of the final winding, and the winding length is not accurate enough. The device can cut the substrate during the substrate conveying process to keep the incision in a horizontal state, and accurately control the length of the final release film winding.

[0018] 2. By connecting multiple lifting springs to the top of the inner wall of the gantry, the bottom of the lifting springs is connected to the lifting block, and the lifting frame is connected between the two lifting blocks. The inner wall of the lifting frame is movably connected to the driving roller. When the release film passes between the driving roller and the roller, the lifting spring rebounds. Due to the rebound effect of the lifting spring, the driving roller is firmly pressed on the upper surface of the substrate, so that the substrate moves forward, adapting to substrates of different thicknesses, and improving the applicability of the device. At the same time, two infrared sensors are installed on the top right side of the top plate to measure the distance the substrate moves forward and control the cutting interval of the cutter, thereby making the cutting length more accurate.

A baffle 26 is fixedly connected to the left outer wall of the workbench 1, and there are two baffles 26. The inner walls of the two baffles 26 are provided with slots 27.
