Abstract
A paper roll carrying device is equipped with movable-type paper clamping arms for clamping paper rolls with different widths. The paper roll carrying device includes two paper clamping arms and two supporting mechanisms. The supporting mechanisms are respectively installed on the corresponding paper clamping arms. Each supporting mechanism includes a first support member, a second support member and a third support member. The supporting mechanism is specially designed to have the take-out slant surfaces on the supporting members. The supporting mechanism can be used to support paper cores with different diameters. When the user intends to remove the paper roll, it is not necessary to release the paper clamping arms.
Claims12
A paper roll carrying device, comprising:
- two paper clamping arms opposed to each other, wherein a paper roll is clamped by the two paper clamping arms, and the paper roll has a paper core;
- two supporting mechanisms respectively installed on corresponding positions of the two paper clamping arms and arranged at a same side of the two paper clamping arms, wherein the paper core is supported by the two supporting mechanisms, and each of the two supporting mechanisms comprises a first support member, a second support member and a third support member, wherein the first support member comprises a first arc-shaped support part and a first stopping part, the second support member comprises a second arc-shaped support part and a second stopping part, the second arc-shaped support part is located beside and arranged around the first arc-shaped support part, the first stopping part and the second stopping part are contacted with each other, the third support member comprises a third arc-shaped support part and a third stopping part, the third arc-shaped support part is located beside and arranged around the second arc-shaped support part, and the second stopping part and the third stopping part are contacted with each other;
- and
- two elastic modules respectively disposed within the two paper clamping arms to provide elastic forces to the corresponding supporting mechanisms,
- wherein while the first arc-shaped support part in one of the two supporting mechanisms is pushed, the corresponding second stopping part is pressed by the corresponding first stopping part, and the corresponding third stopping part is pressed by the corresponding second stopping part, so that the corresponding first arc-shaped support part, the corresponding second arc-shaped support part and the corresponding third arc-shaped support part are simultaneously retracted into the corresponding paper clamping arm.
