Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glass production equipment and relates to a pressure wheel device for improving the online edge cleaning quality of float glass. Background Art
[0002] During the production of float glass, there are indentations from the edge drawing machine and large thickness differences on the edges. The cold end cutting machine cuts a knife mark on the edge of the glass ribbon, and then it is broken and accelerated to the edge bending machine, where the edge is pressed off at once by the pressure wheel to clean the edge.
[0003] The edge bending machine consists of a screw-adjustable lower top wheel and a cylinder-controlled upper pressure wheel, both of which are single steel wheel structures. When cleaning the edges, the lower top wheel holds the knife mark on the edge of the glass. Due to the hard and brittle characteristics of glass, the upper pressure wheel can press the edge of the glass each time it presses down. However, the contact position between the single steel wheel and the glass is point contact. If the steel wheel is adjusted too far outward to increase the contact surface with the glass during edge cleaning, a small protruding block will be produced at the contact point; if the steel wheel is adjusted too far inward to reduce the contact surface with the glass during edge cleaning, a small concave block will be produced at the contact point. This is called the edge cleaning concave and convex circle quality problem. In addition, the upper pressure wheel controlled by the cylinder has a large impact force on the glass, causing the plate surface to vibrate, and it is also easy to form an uneven fracture and offset the online position of the glass. Utility Model Content
[0004] The purpose of the utility model is to provide a pressure wheel device for improving the online edge cleaning quality of float glass in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the stability of the breaking pressure and improve the breaking edge cleaning quality.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a pressure wheel device for improving the online edge cleaning quality of float glass, characterized in that it includes a mounting frame and at least four cams rotatably connected to the mounting frame, the cams are rotatably connected to the mounting frame through a rotating shaft, a sprocket is fixedly provided on the rotating shaft, each sprocket is pulled by a chain, and the convex points of adjacent cams have a phase angle between 120 and 240 degrees.
[0006] Preferably, there are four cams, and the convex points of adjacent cams form a phase angle of 180°.
[0007] A group of multiple cams act on different positions of the glass edge at a certain distance when breaking. Compared with a single pressure wheel, the force applied to the glass during edge pressing is more uniform, which can improve the edge cleaning quality. In addition, the cam method is adopted to make the cam's pressing force on the glass uniform and continuous, reducing the impact force on the glass and greatly reducing the vibration of the glass during breaking.

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 1 and Figure 2 The pressure wheel device for online edge cleaning of float glass shown in the figure comprises a mounting frame 1 and at least four cams 2 rotatably connected to the mounting frame 1, the cams 2 are rotatably connected to the mounting frame 1 via a rotating shaft, a sprocket 3 is fixedly provided on the rotating shaft, each sprocket 3 is pulled by a chain 4, and the convex points of adjacent cams 2 have a phase angle between 120 and 240 degrees.
[0013] Preferably, there are four cams 2, and the protrusions of adjacent cams 2 form a phase angle of 180°.
[0014] A plurality of cams 2 are formed in a group and act on different positions of the edge of the glass at a certain distance when breaking. Compared with a single pressing wheel, the force applied to the glass during edge pressing is more uniform, which can improve the edge cleaning quality. In addition, by adopting the cam 2, the pressing force of the cam 2 on the glass is applied uniformly and continuously, which reduces the impact force on the glass and greatly reduces the vibration of the glass during breaking.
