Film coil thickness accumulation control system

Abstract

The invention belongs to the field of film coil reeling and unreeling equipment, and particularly relates to a film coil thickness accumulation control system. The system comprises an unreeling mechanism, an overlocking device and a driving mechanism used for driving the overlocking device to move in a specific direction, wherein the unreeling mechanism is used for unreeling the film of a film coil and at least comprises a roller reel used for accommodating the film coil, the roller reel can make reciprocating motion along the axis of the roller reel, the overlocking device is used for locking and correcting the moving direction of the film unreeled from the roller reel and is arranged on the moving path of the film unreeled from the unreeling mechanism, the sensing end of the overlocking device points to the surface of the film, and the moving direction of the overlocking device is parallel to the surface of the film and is perpendicular to or intersects with the film moving direction. According to a film coil machined through the system, the thick parts and thin parts are overlapped evenly so as to eliminate thickness accumulation finally, and in this way, the problem of thickness accumulation of a film coil existing in the prior art during film slitting is solved, and then the unqualified rate is reduced.

Description

Technical field [0001] The invention belongs to the field of film roll winding and unwinding equipment, and specifically relates to a film roll thickness accumulation control system. Background technique [0002] Taking into account the possible slippage and deviation between the rollers of the film during the unwinding and unwinding operation along the axis of the rollers, the edger is usually installed to ensure its own reliable conveying effect; the edger is actually The above is an electric eye component, which is generally placed on the side of the film conveying path on the roller, and the electric eye is connected to the controller, and the controller controls the unwinder or feeding mechanism on the film conveying side; the electric eye monitors the travel path of the film, And when the film has a slippage along the roller axis direction, the signal is obtained to transmit to the controller, and then the controller controls the corresponding parts at the film conveying si...

AI Technical Summary

Problems solved by technology

When the above parts are actually used, it is found that due to the working characteristics of the machine itself, the above-mentioned edge locker is often too mechanical to meet the predetermined flexible operation requirements; The thickness of the film surface in the width direction of the film is different, but the thickness of the film length direction tends to be consistent. Once the film is wound into a roll along the length direction of the film, the thicker parts will continue to overlap and accumulate, resulting in a bulging phenomenon in the entire boot roll; It must be corrected when the film roll is sent to the slitting machine for preliminary slitting, otherwise not only will there still be a large number of bulging and drooping phenomena in the follow-up film roll, which will make it easier to produce unqualified products, but the entire film roll is uneven and the appearance Poor, resulting in particularly strong customer complaints; however, there is still no effective way to solve the above problems, often still lock the travel path of the film through the edge locker and then no longer manage it, often affecting the quality of the final product adversely affect
