Uncoiling structure used on double-station uncoiling machine

Abstract

The invention provides an uncoiling structure used on a double-station uncoiling machine, comprising an uncoiling rack, a pair of base paper installation parts which are arranged on the uncoiling rack and used for placing base paper and a pair of uncoiling devices respectively used for driving a pair of base paper to carry out uncoiling, the pair of uncoiling devices are positioned between the pair of base paper installation parts and arranged crosswise in an X shape; according to the scheme, the uncoiling devices on the uncoiling machine, which are respectively used for carrying out uncoiling operation to the base paper, are arranged between the base paper at two ends of the uncoiling rack, and the pair of uncoiling devices are arranged crosswise in the X shape. During uncoiling, the pair of uncoiling devices are corresponding respectively so as to come into contact with the upper sides of the pair of base paper and to drive the base paper for carrying out uncoiling operation. After the layout pattern of the uncoiling devices with above-mentioned structural style is adopted, as the pair of uncoiling devices are crosswise arranged between the base paper in the X shape, the space between the base paper on the uncoiling rack is fully utilized, and thus the longitudinal dimension of the uncoiling rack can be reduced greatly.

Description

technical field [0001] The invention relates to the technical field of household paper processing equipment, in particular to an unwinding structure used on a double-station unwinding machine. Background technique [0002] During the processing of household paper, it is necessary to unwind the base paper rolled into a roll. In the actual base paper unwinding operation, in order to improve unwinding efficiency, save floor space and cost, manufacturers generally set a pair of unwinding structures on the unwinding stand for simultaneous unwinding operations. See attached figure 1 As shown, the left and right ends of the unwind frame 2 are respectively provided with an unwind mechanism for unwinding operation, wherein the unwind device 4 for driving the base paper 3 to unwind is arranged directly below the base paper 3 . When the base paper 3 is unwound, the unwinding device 4 is driven by the cylinder to gradually rise to contact the base paper 3, and the unwinding device 4 m...

Problems solved by technology

In this process, in order to ensure that it can smoothly send the base paper 3 to the unwinding rack 2, the pneumatic paper loading drive arm 7 has a longer overall length, thereby making the entire unwinding rack 2 longer in size, and the corresponding The power of the cylinder used to drive its action is also relatively large, which increases the cost of the whole machine; in addition, when the above-mentioned unwinding device 4 is driving the base paper 3 to perform the unwinding operation, the base paper 3 is subjected to the action of the unwinding device 4 The force is obliquely upward. On the one hand, this type of unwinding force makes the base paper 3 easily slide out from the unwinding frame 2 during the unwinding process; on the other hand, in order to ensure that the unwinding device 4 can unwind normally operation, the driving cylinder needs to have a large driving force
