DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3 As shown, a wide-width unwinding auxiliary support mechanism includes an unwinding air-inflating shaft 1 and a movable plate 2. The movable plate 2 is symmetrically installed with hinges 13 at the side wall away from the unwinding air-inflating shaft 1. In this embodiment, the movable plate 2 is installed on the frame at the feed end of the printing press through the hinge 13, which is convenient for the movable plate 2 to deflect its position. The unwinding air-inflating shaft 1 is vertically arranged with the movable plate 2. A deep groove ball bearing 3 is installed at the roller shaft at one end of the unwinding air-inflating shaft 1. In this embodiment, the other end of the unwinding air-inflating shaft 1 is driven by a motor with a synchronous pulley (this is the prior art and will not be elaborated here). A lower fixed clamping block 4 for supporting the deep groove ball bearing 3 is fixedly installed on one side wall of the movable plate 2.

[0021] The top of the lower fixed clamping block 4 is provided with a U-shaped clamping opening 9 for limiting the position of the deep groove ball bearing 3. The lower fixed clamping block 4 is provided with a notch groove near the two ends, and a reserved hole 10 is provided through the bottom of the notch groove. The lower fixed clamping block 4 is conveniently fixedly installed on the side wall of the movable plate 2 by using bolts to cooperate with the reserved holes 10. An upper movable clamping block 5 for clamping the deep groove ball bearing 3 is provided above the lower fixed clamping block 4. An inverted V-shaped groove 12 for clamping the deep groove ball bearing 3 is provided at the bottom of the upper movable clamping block 5, which is not only convenient for clamping and positioning the deep groove ball bearing 3, but also convenient for limiting the position of the deep groove ball bearing 3, so that it is not easy to deviate from the position. The deep groove ball bearing 3 is located between the upper movable clamping block 5 and the lower fixed clamping block 4.

[0022] A lifting mechanism for controlling the up and down movement of the upper movable clamping block 5 is installed on the movable plate 2. The lifting mechanism includes an L-shaped plate 6 and a cylinder 7. The L-shaped plate 6 is fixedly installed on the side wall of the movable plate 2, and the cylinder 7 is installed at the bottom of the L-shaped plate 6, and the piston rod of the cylinder 7 is connected to the top of the upper movable clamping block 5. Starting the cylinder 7 can conveniently drive the upper movable clamping block 5 to rise and fall, thereby realizing the clamping control of the deep groove ball bearing 3, changing the cumbersome operation of the traditional manual opening of the clamp, and making the operation safer and more convenient. A guide assembly 8 is installed between the upper movable clamping block 5 and the movable plate 2 to improve the stability of the lifting movement of the upper movable clamping block 5.

[0023] The guide assembly 8 includes a linear slide rail 801, a slider 802 and a connecting block 803. The connecting block 803 is fixedly installed on the top of the upper movable clamping block 5 near one end. The slider 802 is connected to the side of the connecting block 803 near the movable plate 2, so that the upper movable clamping block 5 can drive the slider 802 to rise and fall synchronously through the connecting block 803. The linear slide rail 801 is installed on the movable plate 2, and the slider 802 is slidably connected to the linear slide rail 801. Both ends of the linear slide rail 801 are connected to limit blocks 11, which is convenient for limiting the lifting and lowering stroke of the slider 802 so that the slider 802 will not be separated from the linear slide rail 801. A mounting hole is opened through the limit block 11 to facilitate the installation of the limit block 11 on the movable plate 2.

[0024] The working principle of the utility model is as follows: when it is necessary to put a wide material on the unwinding air expansion shaft 1, the cylinder 7 is started to drive the upper movable clamping block 5 to move upward. At the same time, the upper movable clamping block 5 drives the slider 802 to slide synchronously along the linear slide rail 801 through the connecting block 803. When the upper movable clamping block 5 moves up and separates from the deep groove ball bearing 3, the movable plate 2 can be deflected to rotate the movable plate 2 to a position parallel to the unwinding air expansion shaft 1. At this time, there is no obstruction on the end of the unwinding air expansion shaft 1 where the deep groove ball bearing 3 is installed, which makes it convenient to put the wide material on the unwinding air expansion shaft 1. Subsequently, the movable plate 2 is deflected and reset to make the lower fixed clamping block 4 support the bottom of the deep groove ball bearing 3. Then, the cylinder 7 is started to drive the upper movable clamping block 5 to move downward, so that the deep groove ball bearing 3 can be clamped to achieve positioning, so that the unwinding air expansion shaft 1 will not shake during the subsequent rotation process, thereby ensuring the stability of the rotation.

[0025] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
