Coiled material deviation rectifying device of bag making machine

Abstract

The invention discloses a coiled material deviation rectifying device of a bag making machine. The coiled material deviation rectifying device comprises a framework, photoelectric sensors and an accommodating rack. The accommodating rack is arranged on one side of the framework. Compared with the prior art, the coiled material deviation rectifying device is characterized in that a front guide roller and a rear guide roller are arranged on the framework, and the left photoelectric sensor and the right photoelectric sensor are arranged between the two guide rollers and are fixed to the edge of a coiled material; the accommodating rack is arranged on sliding guide rails of a base frame, and limit switches are arranged on two sides of the bottom of the base frame and can limit the accommodating frame when the accommodating frame excessively moves left and right. The coiled material deviation rectifying device has the advantages that the left photoelectric sensor and the right photoelectric sensor are fixed to the edge of the coiled material, and signals can be emitted when the edge of the coiled material is deviated from detection ranges of the photoelectric sensors and are transmitted through a control circuit, so that a brushless motor can rotate clockwise and anticlockwise, the coiled material can return to a correct position, and normal follow-up operation can be guaranteed.

Description

technical field [0001] The invention relates to a deviation correcting and guiding device, in particular to a deviation correcting device which can be used in bag making machines, printing machines, slitting machines and compound machines, and can automatically correct uneven coils or position drift during operation. Background technique [0002] Take the bag making machine as an example, regardless of whether the roll material is plastic, paper or non-woven fabric, these roll materials enter the bag making machine after being cut, printed, and compounded to make bags for people to use. When the coiled material enters the bag making machine, there will be irregular winding, or frictional static electricity between the material and the guide roller, etc., which will cause the coiled material to drift left and right during the bag making process, and finally lead to Sequence length tracking deviation, the photoelectric eye cannot catch the cursor, the length is different, and ...
