Small spray painting cloth unwinding mechanism and use method thereof

Abstract

The invention relates to the technical field of glass reinforced plastic pipelines, and specifically discloses a small spray painting cloth unwinding mechanism and a use method thereof. The small spray painting cloth unwinding mechanism comprises an upper pressing wheel, a lower pressing wheel and a rotating shaft. The upper pressing wheel, the lower pressing wheel and the rotating shaft are connected to frame plates on the two sides in a rotating manner. An upper pressing plate is located above a lower pressing plate, and the upper pressing plate and the lower pressing plate are in close cooperation. A spray painting cloth roll is coaxially and fixedly arranged on the rotating shaft. A gear and a friction wheel are coaxially fixed to one end of the rotating shaft. A supporting rod is arranged between the lower pressing wheel and the rotating shaft. The upper end portion of the supporting rod is connected with a lever in a rotating manner. One end of the lever is connected with a balance weight roller in a rotating manner. Slide grooves are formed in the frame plates and correspond to the balance weight roller. A rotating shaft of the balance weight roller is located in the slide grooves and can slide. The other end of the lever is of a forked structure, a tooth block facing the gear is arranged on the end portion of the lower end of a fork, a groove hole is formed in the end portion of the upper end of the fork, and a friction block facing the friction wheel is arranged in the groove hole. By means of the small spray painting cloth unwinding mechanism and the use method, unwinding stability can be improved, and the unwinding speed can be automatically controlled.

Description

technical field [0001] The invention relates to the field of advertisement production, in particular to a small inkjet cloth unwinding mechanism and a using method thereof. Background technique [0002] The structure of the existing inkjet cloth unwinding mechanism can only stop the pulled out inkjet cloth, but cannot stop the wound inkjet cloth roll, causing the inkjet cloth roll to continue to rotate in a slack state, affecting the unwinding quality; in addition , the unwinding speed of the inkjet cloth roll is too fast, which also has a great impact on the stability of the unwinding, and needs to increase the control device, which is not easy to operate and difficult to meet the needs of production and use. Therefore, we design an inkjet cloth unwinding mechanism. In view of Therefore, we propose a small inkjet cloth unwinding mechanism and its application method. Contents of the invention [0003] The purpose of the present invention is to provide a small inkjet cloth...
