Woven bag double-face rotary press

Abstract

The invention discloses a woven bag double-face rotary press. The woven bag double-face rotary press comprises a rack, a feeding mechanism, conveyer belts, auxiliary clamping belts and transfer rolls, and is characterized in that the first conveyer belt and the third conveyer belt are arranged in the rack, the second conveyer belt is arranged at the rear end of the first conveyer belt and the rear end of the third conveyer belt and is of a quadrangled structure supported by four turning rolls, the feeding mechanism is arranged at the front end of the first conveyer belt, the transfer rolls are arranged above the first conveyer belt and the third conveyer belt, the first auxiliary clamping belt is arranged on the periphery of the upper side of the first conveyer belt and the periphery of the upper side of the second conveyer belt, and the second auxiliary clamping belt is arranged on the working face of the third conveyer belt. The whole press operates automatically during the processes of feeding, transfer, printing and rotating; besides, due to the adoption of belt conveying, the clamping effect is good, the conveyer belts and the auxiliary clamping belts can effectively clamp a woven bag and convey the woven bag, and the phenomenon that the woven bag deviates and twists in the conveying process can not occur; meanwhile, the need for fast overhaul and maintenance can be met due to the arrangement of an air cylinder jacking device.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a double-sided printing machine for woven bags. Background technique [0002] The woven bag printing machine is a machine used to print text and images on woven bags, which is a kind of printing machine. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Printed onto a woven bag, thus replicating the same print as the printing plate. [0003] For example, a double-sided printing machine disclosed in Chinese patent CN102963119 is aimed at roll-shaped woven bags, which can realize automatic continuous printing of front and back sides. The turning device disclosed in the Chinese patent CN2618755Y used in a double-sided printing ...

Problems solved by technology

However, this structure has defects. In actual use, because the turning wheel is relatively narrow (combined with the accompanying drawings to understand the detailed plan), and the number is two, in the actual turning process, the phenomenon of deflection and twisting of the woven bag often occurs. The applicant made improvements according to actual needs
