Description

Cantilever sheet coiling mechanism

Technical Field

The utility model relates to the technical field of sheet production, in particular to a cantilever sheet winding device.

Background

The sheet winding device is positioned at the downstream of the sheet production line and can wind the sheet into coiled materials by utilizing an inflatable shaft. When the traditional sheet coiling mechanism is used for coil stripping, a coiled material and an inflatable shaft are detached from the coiling mechanism together by using a forklift or a cart and transported to a coil stripping area, the inflatable shaft is pulled away from the coiled material in the coil stripping area, and finally the inflatable shaft is installed and returned to the coiling mechanism. Therefore, the coil unloading process of the traditional sheet coiling device is more complicated.

In addition, when coil stripping of a coil with a large coil diameter is performed, the friction force between the coil and the air-expanding shaft is large due to the self-sagging effect generated by the coil. When the inflatable shaft is pulled away from the coiled material, the sheet contacted with the inflatable shaft is pulled by the inflatable shaft to cause uneven end surfaces on two sides of the coiled material, which requires further manual adjustment.

Fig. 1-3 show a cantilever sheet winding apparatus 100 (hereinafter referred to as winding apparatus 100) according to the present utility model, where the winding apparatus 100 is disposed downstream of a corresponding sheet production line to wind a formed sheet into a roll, and is particularly suitable for winding operations of large-roll-diameter sheets.

As shown in the drawing, the winding device 100 includes a frame 1 that can be fixedly supported on the ground or a pedestal, an electrical cabinet 2 fixedly disposed on the frame 1, a pair of transition rollers 3 rotatably disposed at the rear of the frame 1, and a pair of winding and unwinding units.

The frame 1 comprises a base 11 positioned at the lower part and a frame body 12 fixedly arranged on the base 11, wherein the base 11 is firmly fixed on the ground or a pedestal through foundation bolts. Both the base 11 and the frame 12 are made of rigid materials to provide sufficient structural strength for the winding device 100. The electrical cabinet 2 is fixedly disposed on the frame 12, and can provide electrical protection (such as short-circuit protection, circuit breaking protection, overvoltage protection, etc.) for the winding device 100. A pair of transition rollers 3 are arranged up and down for adjusting the winding angle at the time of winding the sheet and maintaining the surface tension of the sheet to prevent wrinkles from occurring at the time of winding the sheet to cause winding failure.

The rolling and coil unloading units are arranged front and back, and each rolling and coil unloading unit comprises a rolling motor 4 fixedly arranged on a base 11, a driving roller 5 rotatably arranged on a frame body 12, a movable supporting piece 6 arranged left and right with the driving roller 5, a pair of coil unloading cylinders 7 arranged on the frame body 12, a push plate 8 capable of being pushed by the coil unloading cylinders 7 and a rotatable air expansion shaft 9.

The winding motor 4 is used for driving the air expansion shaft 9 to rotate, and a rotatable first transmission head 41 is arranged on the winding motor 4. The driving roller 5 is used as a driving part of the winding motor 4 and the air expansion shaft 9, and the driving roller 5 is fixedly provided with a second driving head 51 and a quick-release joint 52 exposed from the frame body 12. The second driving head 51 is located on the upper side of the first driving head 41, and the first and second driving heads are connected in a driving manner by a belt or a chain (not shown).

The inflatable shaft 9 defines a shaft axis extending from left to right and has a first end and a second end that are remote from each other. The quick disconnect 52 is configured and adapted to removably connect to the first end of the balloon shaft 9 to provide for synchronous rotation of the balloon shaft 9.

The top of the movable support 6 is configured and adapted to support a second end of the inflatable shaft 9. The movable support 6 has an operating position in contact with the inflatable shaft 9 to support its rotation and an exit position in which the coil moves along the path when completely exiting the coil stripper. Specifically, the winding mechanism provided in this embodiment is further provided with a stand 61 fixedly supported on the ground or the pedestal and far away from the coil moving path during coil unloading, and the movable support 6 is rotatably hinged on the stand 61 around the stand 61, so that the movable support 6 can be switched back and forth between the working position and the withdrawing position. It will be appreciated that in other embodiments, the movable support may be moved up and down, left and right, or folded to effect the back and forth switching between the working and the withdrawn positions.

The coil unloading cylinder 7 is arranged at the driving roller 5 and is used for pushing out the coiled material wound on the air expansion shaft 9. The coil stripping cylinder 7 includes a cylinder body 71 fixedly attached to the frame body 12 and a cylinder shaft 72 that is retractable with respect to the cylinder body 71 in the axial line direction (i.e., the left-right direction in the present embodiment) of the balloon shaft 9. The push plate 8 is constructed in a semi-annular shape surrounding the quick release joint 52 from the outside, and is fixedly attached to the front portions of the cylinder shafts 72 of the pair of coil-unloading cylinders 7 and contacts the coil wound on the balloon shaft 9.

The following describes the working principle of the winding device 100: when in winding, the winding motor 4 drives the air expansion shaft 9 to rotate, and the sheet is wound on a winding sleeve on the air expansion shaft 9. When coil unloading is needed, the coil on the air expansion shaft 9 is supported or clamped by a forklift and other mobile equipment, the movable supporting piece 6 is switched to the withdrawing position, a pair of coil unloading cylinders 7 act, and the coil is pushed away from the air expansion shaft 9 by the push plate 8, so that coil unloading operation is completed. In the process, the inflatable shaft 9 does not need to be disassembled and assembled, so that the process is convenient and quick. In addition, as the push plate 8 always contacts with one side end surface of the coiled material in the coil unloading process, the condition that the end surface of the coiled material is uneven due to friction force between the coiled material and the air expansion shaft can be effectively avoided or relieved.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the foregoing embodiments, which have been described in the foregoing embodiments and description merely illustrates the principles of the utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, the scope of which is defined in the appended claims, specification and their equivalents.
