DETAILED DESCRIPTION

[0028] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] In the following description, "left", "right", "front", "back", "up", and "down" are oriented in the perspective of the front view.

[0030] Embodiment one: in some embodiments, referring to the accompanying drawings of the specification Figures 1-3 A convenient-to-install uncoiler pressure roller device, comprising a support frame 1, a constant force support structure 2, and a combined pressure roller 3.

[0033] In this embodiment, when the easy-to-install uncoiler pressure roller device is working normally, multiple assembly blocks 32 are fixedly installed on the mounting shaft 31 with bolts. In the initial state, the reset module 23 supports the constant force module 22, so that the support module 21, the mounting shaft 31 on the support module 21, and the assembly blocks 32 are in a position that does not obstruct the installation of the steel coil. After the steel coil is installed, the reset module 23 releases the support of the constant force module 22. The constant force module 22 drives the support module 21 to rotate, and moves the mounting shaft 31 at the end of the support module 21, so that the assembly blocks 32 press the steel coil. During the continuous unfolding of the steel coil, the constant force module 22 drives the support module 21 to rotate. The assembly block 32 is always pressed against the steel coil with a constant force, thus ensuring a constant pressing effect during the unwinding of the steel coil. When the steel coil needs to be replaced, the reset module 23 supports the constant force module 22. At this time, the support module 21 rotates, causing the mounting shaft 31 and the assembly block 32 to move upward automatically, avoiding obstruction of the steel coil installation. After a period of use, if the surface of a certain assembly block 32 is worn, the worn assembly block 32 can be removed and replaced individually. In this process, it is not necessary to remove the mounting shaft 31 from the support module 21, thus facilitating the installation and replacement of the assembly block 32.
