Print cloth unwinding mechanism with damping

Abstract

The invention discloses a print cloth unwinding mechanism with damping and belongs to the field of poster printing mechanical equipment. The print cloth unwinding mechanism with the damping comprises a fixed base, an unwinding bracket, an unwinding metering mechanism body and an unwinding damping mechanism body. An unwinding roller is horizontally and rotationally connected to the unwinding bracket. A rotating shaft is rotationally connected to a rotary bracket. Rotary air cylinders are symmetrically and obliquely arranged on the two sides of the fixed base correspondingly. Connection plates are arranged between the output ends of the rotary air cylinders and the rotating shaft. A pressing rod is arranged on the upper side of the rotating shaft. A metering rolling wheel is horizontally and rotationally connected to the side, close to the unwinding roller, of the pressing rod. A cloth bearing roller is horizontally and rotationally connected to the upper side of a cloth bearing bracket. A damping roller is horizontally arranged on the upper side of the cloth bearing roller. A stretched spring is arranged between a supporting plate and the unwinding bracket. According to the print cloth unwinding mechanism with the damping, the structural design is reasonable, unwinding can be conducted on print cloth quickly, efficiently, stably and precisely as required, and the production and using requirements are met.

[0002] Outdoor advertising can quickly enhance the corporate image, disseminate business information and establish a city image. The common psychological characteristics and customs are set up, repeated publicity among fixed consumer groups, deepening the impression, and the publicity effect is good. Nowadays, outdoor advertisements generally use the form of inkjet cloth for outdoor advertisements. Inkjet cloth is commonly known as light box cloth. Polyvinyl chloride is used as raw material to produce after a certain production process. It is mainly used as an inkjet material for outdoor advertising inkjet painting. The existing inkjet cloth is usually stored in the form of inkjet cloth rolls. When the inkjet cloth is printed, it needs to The existing inkjet cloth unwinding mechanism has a complex structure and troublesome operation. It is difficult to quickly and efficiently unwind the inkjet cloth accurately, and the length of the inkjet cloth unwinding cannot be measured during the unwinding process. During the unwinding process of the inkjet cloth, the inkjet cloth is often unrolled excessively due to inertia, and the entire inkjet cloth roll will become loose during the unwinding process, which will affect the efficiency and quality of the inkjet cloth unwinding, and it is difficult to meet the production requirements. needs
