Single-plate swing arm type material collecting set

Abstract

The invention discloses a single-plate swing arm type material collecting set. The single-plate swing arm type material collecting set comprises a rack, a rewinding leaning roller fixedly arranged on the rack, a material collecting roller assembly and a reciprocating swing assembly, wherein the material collecting roller assembly comprises a material collecting arm and a material collecting roller; one end of the material collecting arm is hinged to the rack, and the material collecting roller is located at the end, away from the end, hinged to the rack, of the material collecting arm; and the output end of the reciprocating swing assembly is connected with the material collecting arm, the material collecting arm rotates around a hinge shaft of the material collecting arm and the rack through movement of the output end of the reciprocating swing assembly, and therefore the material collecting roller moves towards the rewinding leaning roller, a radian swing type structure is adopted for winding, and winding press-fit points are kept at the same position.

Description

technical field [0001] The invention belongs to the technical field of material receiving devices for printing machines, and in particular relates to a single-disc swing arm type material receiving group. Background technique [0002] After the printing machine finishes printing the substrate, the substrate needs to be rolled up, so as to facilitate the transportation and storage of the substrate, and facilitate the next production process. The traditional winding mechanism often directly uses the winding roller to wind the substrate for winding, which makes the tightness of the rolled material poor, and it is difficult to ensure the uniformity of the winding; in addition, the traditional winding mechanism During the rolling process, the sudden change of tension often leads to jumping, resulting in irregular coils; finally, as the winding progresses, the diameter of the coil gradually increases, and the constant speed will inevitably lead to a gradual increase in the outermo...

Problems solved by technology

The traditional winding mechanism often directly uses the winding roller to wind the substrate for winding, which makes the tightness of the rolled material poor, and it is difficult to ensure the uniformity of the winding; in addition, the traditional winding mechanism During the rolling process, the sudden change of tension often leads to jumping, resulting in irregular coils; finally, as the winding progresses, the diameter of the coil gradually increases, and the constant speed will inevitably lead to a gradual increase in the outermost layer of the coil. The traditional winding mechanism rotates at a constant speed, so as the diameter of the coil increases, the speed of the line will increase, which will inevitably lead to an increase in the tension of the rewinding substrate, resulting in excessive hand-drawn deformation of the substrate and even damage to the substrate
