The left and right outer shells 1 and 101 are configured as an inverted L-shape and are detachably fixedly connected by several sets of nuts 2, a fixed shaft 201, and a limiting ring 203. A narrow slit 103 is provided between the tops of the left and right outer shells 1 and 101.

The fixed shaft 201 is located between the left and right outer shells 1 and 101, and a guide wheel 202 is rotatably connected to the middle section of the fixed shaft 201.

[0034] It should be noted that the bottom end of the guide wheel 202 and the lowest end of the hook-shaped plate 4 are on the same plane.

[0035] It should be noted that, in addition, the reference Figure 7 As shown, the limiting ring 203 is sleeved on both ends of the fixed shaft 201, and the nut 2 is threaded to the end of the fixed shaft 201. The side walls of the left outer shell 1 and the right outer shell 101 are provided with several through holes 102. The two ends of the fixed shaft 201 pass through the through holes 102 located on the left outer shell 1 and the right outer shell 101 respectively. The two limiting rings 203 are located on the inner side of the left outer shell 1 and the right outer shell 101 respectively.

[0036] In an optional embodiment: the through holes 102 on the left outer shell 1 and the right outer shell 101 are equally spaced, the portion of the fixed shaft 201 located outside the limiting ring 203 is threaded, and the nut 2 located on the outer side of the left outer shell 1 and the right outer shell 101 is threadedly connected to the fixed shaft 201 extending out of the through hole 102.

[0037] In an optional embodiment: a rotating groove is provided in the middle section of the fixed shaft 201, and the guide wheel 202 is located in the rotating groove to limit the guide wheel 202 from sliding left and right on the fixed shaft 201.

[0038] In an optional embodiment: the bent connecting plate 3 is detachably fixed to the top of the left outer shell 1 and the right outer shell 101 by the first washer 302 and the first fastener 303, and the lower part of the bent connecting plate 3 is provided with an installation port 301.

[0039] It should be noted that the first fastener 303 includes a bolt and a nut. The head of the bolt is located inside the left outer shell 1 and the right outer shell 101. The bolt passes through the narrow slit 103 and the first washer 302 and is threadedly connected to the nut.

[0040] In an optional embodiment: the hook-shaped bend plate 4 is detachably fixedly connected to the top of the left outer shell 1 and the right outer shell 101 by a connecting block 401, a second washer 402 and a second fastener 403, and the connecting block 401 is fixedly connected to the end of the hook-shaped bend plate 4.

[0041] It should be noted that the second fastener 403 includes a bolt and a nut. The head of the bolt is located inside the left outer shell 1 and the right outer shell 101. The bolt passes through the narrow slit 103 and the second washer 402 and is threadedly connected to the nut.

[0042] The working principle of this device will now be explained through its working process: First, refer to... Figure 6 As shown, a brief introduction to the installation conditions of this device is given. In the process of manufacturing LCD glass, a packaging machine is required to cut paper into specified sizes. This includes a paper feeding platform 5 and paper 6 conveyed on it. Due to possible imbalances in the conveying system, asynchronous cutting and conveying, etc., the force on paper 6 may shift, which may cause paper 6 to easily deviate and ultimately affect the production line of LCD glass.

[0043] The device is installed on both sides of the paper feeding platform 5. Specifically, the bent connecting plate 3 is fixed to both sides of the paper feeding platform 5 by screws, bolts, etc., passing through the mounting port 301. It should be noted that the lowest end of the hook-shaped bent plate 4 and the guide wheel 202 will press against the top surface of the paper 6. The orientation of the hook-shaped bent plate 4 is opposite to the feeding direction of the paper 6. The long side of the left outer shell 1 or the right outer shell 101 is parallel to the feeding direction of the paper 6. That is, several guide wheels 202 roll in the feeding direction of the paper 6. The lowest end of the hook-shaped bent plate 4 presses against the top surface of the paper 6, applying a downward force to position the paper 6. The several guide wheels 202 rolling due to the feeding of the paper 6 will stabilize the surface tension of the paper 6, thereby making it less likely for the paper 6 to deviate during feeding.

[0044] In actual use, multiple of these devices can be symmetrically set on both sides of the paper feeding platform 5 according to the offset of the paper 6, so as to better prevent the paper 6 from deviating.

[0045] This device, through the arrangement of the left outer shell 1, the right outer shell 101 and the narrow slit 103, utilizes the narrow slit 103 to facilitate the bolts in the first fastener 303 or the second fastener 403 to slide into specific positions on the top of the left outer shell 1 and the right outer shell 101 and be fastened with nuts, which greatly improves the installation efficiency of the bent connecting plate 3 and the hook-shaped bent plate 4. As a result, this device is not only simple in structure and low in cost, but also easy to assemble.

[0046] This device, through the setting of hook-shaped bending plate 4 and several guide wheels 202, utilizes the positioning of paper 6 by hook-shaped bending plate 4 and the stabilization of surface tension of paper 6 by several guide wheels 202, thereby achieving the prevention of paper 6 from deviation and ultimately improving the production efficiency of LCD glass production line.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
