[0002] Tempered glass is obtained by cutting ordinary annealed glass into required sizes, heating it to about 700 degrees, close to the softening point, and then cooling it quickly and evenly. After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which improves the bending and impact resistance of the glass. Its strength is about four times that of ordinary annealed glass. It is widely used in life and production.

DETAILED DESCRIPTION

[0019] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present embodiment disclosure as detailed in the appended claims.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] like Figures 1 to 3 As shown, it is a structural diagram of a surface coating device for tempered glass provided by an embodiment of the present invention, comprising a frame 1, on which a pair of coating rollers 9 are installed, the two coating rollers 9 rotate in opposite directions, and a gap for tempered glass 10 to pass through is provided between the two coating rollers 9, and a smoothing mechanism 6 and a film cutting mechanism 7 are provided in sequence at the output end position of the frame 1 corresponding to the coating roller 9, wherein the smoothing mechanism 6 is used to eliminate bubbles between the coating and the tempered glass 10, and the film cutting mechanism 7 is used to cut the coating, and the smoothing mechanism 6 includes a first smoothing component 601 and a second smoothing component 602 which are arranged in sequence 602, the first smoothing component 601 includes a rotating roller I6011 and a rotating roller II6012 with opposite rotation directions, a gap is provided between the rotating roller I6011 and the rotating roller II6012 for the tempered glass 10 to pass through, the rotation speed of the rotating roller I6011 is greater than that of the rotating roller II6012, the second smoothing component 602 includes a rotating roller III6021 and a rotating roller IV6022 with opposite rotation directions, a gap is provided between the rotating roller III6021 and the rotating roller IV6022 for the tempered glass 10 to pass through, the rotation speed of the rotating roller IV6022 is greater than that of the rotating roller III6021.

[0022] In the embodiment of the present invention, the two coating rollers 9 can coat both sides of the tempered glass 10 at the same time. After the coating is completed, the smoothing mechanism 6 eliminates the bubbles between the coating and the tempered glass 10, and then the tempered glass 10 enters the film cutting mechanism 7 to cut the coating.

[0023] Here, for rotating roller I6011, rotating roller II6012, rotating roller III6021 and rotating roller IV6022, their rotation speeds are Va, Vb, Vb and Va respectively, rotating roller I6011 and rotating roller III6021 have the same rotation direction, rotating roller II6012 and rotating roller IV6022 have the same rotation direction, that is, rotating roller I6011 and rotating roller II6012 form a group of differential rollers, and rotating roller III6021 and rotating roller IV6022 form a group of differential rollers.

[0024] When the tempered glass 10 enters between the rotating roller I6011 and the rotating roller III6021, due to Va>Vb, based on the principle of differential speed, the rotating roller I6011 has a better bubble removal effect on the upper surface of the tempered glass 10 than the rotating roller II6012. When the tempered glass 10 continues to enter the position of the rotating roller II6012 and the rotating roller IV6022, due to Va>Vb, the rotating roller IV6022 has a better bubble removal effect on the lower surface of the tempered glass 10 than the rotating roller III6021. Ultimately, an efficient smoothing effect on both sides of the tempered glass 10 is achieved.

[0025] like Figure 4 As shown, as a preferred embodiment of the present invention, the rotating roller I6011 includes a roller body 60111, and the surface of the roller body 60111 is provided with a plurality of smoothing edges 60112 extending in the axial direction thereof, and the smoothing edges 60112 are spiral structures.

[0026] In the embodiment of the present invention, the smoothing edge 60112 is a spiral structure, and similarly, the rotating roller II6012, the rotating roller III6021 and the rotating roller IV6022 are structurally identical. The spiral smoothing edge 60112 can squeeze and drive the bubbles to both sides of the tempered glass 10 to achieve the effect of squeezing out the bubbles.

[0027] like Figure 1 As shown, as another preferred embodiment of the present invention, two groups of unloading rollers 2 are also installed on the frame 1, and the coating on the unloading rollers 2 is respectively connected to the two coating rollers 9, and a tensioning adjuster 3 is also installed at the position between the unloading roller 2 and the coating roller 9 of the frame 1.

[0028] In the embodiment of the present invention, the tension regulator 3 realizes the tension adjustment effect of the coating, which is a prior art, and the present embodiment does not provide a detailed description of its structure, principle, etc. In order to simplify the technical solution, the present embodiment does not provide a detailed description of the driving structure for driving the coating roller 9 to rotate.

[0029] like Figure 1 As shown, as another preferred embodiment of the present invention, a loading conveyor belt 4 is installed at the input end position of the frame 1 corresponding to the coating roller 9, and a discharging conveyor belt 8 is installed at the discharging end position of the frame 1 corresponding to the film cutting mechanism 7.

[0030] In the embodiment of the present invention, the purpose of setting the loading conveyor belt 4 and the discharging conveyor belt 8 is to facilitate the loading and unloading of the tempered glass 10. In addition, a pair of material transfer rollers 5 are installed at the position between the frame 1 corresponding to the smoothing mechanism 6 and the coating roller 9. A gap is provided between the two material transfer rollers 5 for the tempered glass 10 to pass through. The material transfer rollers 5 are used to feed the tempered glass 10 into the smoothing mechanism 6. Here, the driving structure for driving the material transfer rollers 5 to rotate is not specifically described in this embodiment.

[0031] This embodiment uses an example of a driving structure. Here, the shaft ends of the two material transfer rollers 5 are provided with gears that mesh with each other, and one of the gears is driven to rotate by a motor reducer. At this time, the two material transfer rollers 5 can rotate synchronously and in opposite directions.

[0032] like Figure 5 As shown, as another preferred embodiment of the present invention, the film cutting mechanism 7 includes a movable knife 703 and a fixed knife 704, the fixed knife 704 is fixed on the frame 1, and the movable knife 703 is movably installed on the frame 1, and a driving member for driving the movable knife 703 to approach or move away from the fixed knife 704 is also installed on the frame 1.

[0033] In the embodiment of the present invention, the driving member for driving the movable knife 703 may be a device such as a cylinder or an oil cylinder, or may be other structures with similar functions, and no redundant description is given in this embodiment.

[0034] In order to facilitate the tempered glass 10 to better enter the position of the movable knife 703 and the fixed knife 704, the film cutting mechanism 7 also includes a first guide roller 701 and a second guide roller 702. The first guide roller 701 and the second guide roller 702 are respectively located at the two sides of the fixed knife 704, and are used to guide and support the movement of the tempered glass 10.

[0035] In combination with the above embodiments, it is easy to know that the working principle of the present invention is: the two coating rollers 9 can coat both sides of the tempered glass 10 at the same time. After the coating is completed, the transfer roller 5 feeds the tempered glass 10 into the smoothing mechanism 6. When the tempered glass 10 enters between the rotating roller I6011 and the rotating roller III6021, due to Va>Vb, based on the principle of differential speed, the rotating roller I6011 has a better bubble removal effect on the upper surface of the tempered glass 10 than the rotating roller II6012. When the tempered glass 10 continues to enter the rotating roller II6 012 and rotating roller IV6022, due to Va>Vb, the debubbling effect of rotating roller IV6022 on the lower surface of the tempered glass 10 is better than that of rotating roller III6021. Finally, the efficient smoothing effect on both sides of the tempered glass 10 is achieved. After the smoothing is completed, the tempered glass 10 enters the position of the movable knife 703 and the fixed knife 704 under the action of the first guide roller 701, the driving part is started, the movable knife 703 approaches the fixed knife 704, cuts off the coating, and then the unloading of the tempered glass 10 is completed through the discharge conveyor belt 8.

[0036] It is necessary to explain that, in order to simplify the technical solution, the controller, photoelectric sensor switch, etc. that the entire device should have are not specifically described in this embodiment. However, when technical personnel in this field actually apply this embodiment, they know or should know how to arrange the above-mentioned controller, photoelectric sensor switch, etc. based on the description of this embodiment.
