Problems solved by technology

[0002] In the prior art, conventional unwinding devices for packaging and printing paper bags use integrated equipment. The equipment has a paper loading shaft for paper loading. For the paper loading operation of paper bags, the air must be inflated manually. The shaft (upper paper shaft) is put into the roll material core barrel. However, the large-format roll material will inevitably lead to a large weight of the inflated shaft. Therefore, the usual practice is to lift it up by two people. The long input time not only makes the labor intensity of the workers very high, but also causes the equipment to be shut down for a long time due to the long installation time, which seriously affects the output. In addition, the unreasonable design of the upper paper part makes the paper tension unstable and prone to running Partial problem

Embodiment Construction

[0025] The shaftless paper unwinding device of the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] As shown in the figure, the shaftless paper unwinding device of the present invention includes a paper feeding mechanism 200, a lifting mechanism 300 for driving the lifting and lowering of the paper feeding mechanism 200, and a tension control mechanism 400 for controlling the tension of the paper. It can be seen from the figure, The paper feeding mechanism 200 includes a pair of paper roll swing arms 205 installed on one main shaft 201, and two clamping devices respectively installed on the two paper roll swing arms 205 for adjusting one of the pair of paper roll swing arms 205. The swing arm adjusting device for the distance and the brake 206 installed on the paper roll swing arm 205 for braking the clamping device, wherein the main shaft 201 is installed on the two wall panels through th...

Abstract

The invention discloses a shaftless paper feeding and unwinding device. The paper feeding device comprises a paper feeding mechanism, a lifting mechanism and a tension control mechanism, the paper feeding mechanism further comprises a pair of clamping devices installed at the front ends of a pair of paper roll swing arms and a swing arm adjusting device, and the distance between the pair of paper roll swing arms is adjusted through the swing arm adjusting device so that a paper roll can be clamped by the clamping devices. The paper feeding mechanism can be lifted through the paper roll lifting mechanism, so that the tension of paper in a paper roll is controlled through the tension control mechanism, and the unwinding operation of the paper is achieved. The paper roll loading device has the advantages that paper rolls can be loaded quickly and conveniently, loading efficiency is high, and labor intensity is greatly reduced. And the tension control mechanism is skillfully matched with the paper roll swing arm, so that the paper tension is stable, and the production quality is improved. And the problem of deviation in the production process is effectively avoided, and the production quality is further improved.

Description

technical field [0001] The invention relates to a packaging printing and paper bag making equipment, in particular to a shaftless paper unwinding device. Background technique [0002] In the prior art, the conventional packaging and printing paper bag making and unwinding devices all use integrated equipment, which has a paper feeding shaft for feeding paper. For the paper feeding operation of the paper bag, the air must be manually inflated The shaft (upper paper shaft) is put into the coil core. However, the large-format coil will inevitably lead to a large weight of the air-inflating shaft. Therefore, the usual practice is to need two people to lift the operation, which is difficult to load and difficult to install. The long entry time not only makes the labor intensity of the workers very high, but also causes the equipment to be shut down for a long time due to the long installation time, which seriously affects the output. In addition, the unreasonable design of the pa...
