Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to a method and a device for processing the surface of a roller. Background Art

[0002] In float glass production, the glass sheet is formed on the tin liquid surface of the tin bath. Before exiting the tin bath and entering the annealing zone (i.e. the transition zone between the tin bath and the annealing zone), a transition roller is used to lift the glass above the lip of the tin bath. During this process, the working environment of the transition roller is harsh, and the surface of the transition roller is easily contaminated and attached with a variety of solid objects. When the relatively soft lower surface of the glass contacts the transition roller, the solid objects attached to the roller will damage the surface of the glass, thereby reducing the quality of the glass, so the surface of the roller needs to be treated.

[0030] refer to Figure 1 According to the first aspect of the present invention, the method for treating the surface of a roller comprises the following steps: heating the surface of the roller 103 to a preset temperature and filling the working environment of the roller 103 with a working gas, wherein the working gas comprises O2 and SO2, and the preset temperature is between 590 and 610°C; making the dry pine wood strips 109 contact with the surface of the roller 103, so that: the dry pine wood strips 109 react with the working gas at the preset temperature to generate sulfur-carbon compounds, and the sulfur-carbon compounds adhere to the surface of the roller 103.

[0031] Specifically, dry pine wood strips are high molecular polymers, the main components of which are carbohydrates, phenolic compounds, terpenoids, fatty acids, alcohols, proteins and trace inorganic substances. The chemical formula of dry pine wood strips can be roughly regarded as C x H y O z When dry pine wood strips are heated to 590-610℃, carbonization reaction will occur. The chemical formula of carbonization reaction is C x H y O z +O2——aCO2+bCO+dC+eH2O; the carbon generated after carbonization reacts with SO2 in the working gas, and the chemical formula is C+SO2——CO2+S, C+S——CS, 3C+2S——C3S2; thus, the generated sulfur-carbon compounds can reduce the friction between the roller 103 and the surface of the glass 101 placed on the roller 103, reduce the damage to the surface of the glass 101, and improve the quality of the glass 101.

[0032] In some embodiments of the present invention, the sulfur-carbon compound includes at least one of CS2, CS, and C3S2, wherein, when the temperature is between 590 and 610°C, CS2 is a colorless liquid, CS is a red powdery crystal, and C3S2 is a red liquid. Thus, the generated sulfur-carbon compound can better lubricate the contact surface between the roller 103 and the glass 101.

[0033] In some embodiments of the present invention, the method also includes the following steps: while maintaining the dry pine wood strips 109 in contact with the surface of the roller 103: moving the dry pine wood strips 109 back and forth along the axial direction of the roller 103, and / or rotating the roller 103 around its own axis, thereby increasing the contact area between the dry pine wood strips 109 and the roller 103, and allowing a larger surface area of ​​the roller 103 to be processed.

[0034] In some embodiments of the present invention, the method also includes the following steps: when the roller 103 rotates around its own axis, glass 101 is placed above the roller 103, so that the sulfur-carbon compounds generated by the dry pine wood strips 109 on the surface of the roller 103 can be moved to the contact surface between the roller 103 and the glass 101 through the rotation of the roller 103 in time for lubrication, thereby improving the utilization rate.

[0035] refer to Figure 1 According to the second aspect of the present invention, the device for treating the surface of a roller is applied to implement the method of the first aspect. The device includes dry pine wood strips 109, a pressing mechanism 102 and a translation mechanism 110; the pressing mechanism 102 is used to press the dry pine wood strips 109 on the surface of the roller 103, the translation mechanism 110 is placed with the dry pine wood strips 109, and the pressing mechanism 102 is installed. The translation mechanism 110 is used to drive the pressing mechanism 102 and the dry pine wood strips 109 to move along the axial direction of the roller 103.

[0036] In summary, the pressure mechanism 102 presses the dry pine wood strips 109 against the surface of the roller 103, so that the dry pine wood strips 109 and the surface of the roller 103 have friction, and then the translation mechanism 110 is used to drive the dry pine wood strips 109 to move along the axial direction of the roller 103. In this way, the friction between the dry pine wood strips 109 and the roller 103 can be used to effectively clean the solid matter on the surface of the roller 103. The purpose of the device in the prior art is only to clean the solid matter on the surface of the roller 103, or to directly replace the roller 103. The dry pine wood strips 109 in the present invention will be carbonized at a preset temperature, and after carbonization, they will react with O2 and SO2 in the working gas to generate sulfur-carbon compounds. The sulfur-carbon compounds can reduce the friction between the roller 103 and the surface of the glass 101 placed on the roller 103, reduce the damage to the surface of the glass 101, and improve the quality of the glass 101, thereby achieving the effect of protecting the surface of the glass 101 from two aspects with one device.

[0037] Specifically, the pressurizing mechanism 102 may be a common pressurizing device such as hydraulic pressurizing, pneumatic pressurizing, etc., which is used to apply pressure to the dry pine wood strips 109 .

[0038] refer to Figure 1 In some embodiments of the present invention, the dry pine wood strip 109 includes a first end 113, a second end 111 and a fulcrum portion 112, and the fulcrum portion 112 is disposed between the first end 113 and the second end 111;

[0039] The fulcrum 112 is placed on the translation mechanism 110, and the dry pine wood strip 109 can rotate around the fulcrum 112. The first end 113 abuts against the bottom of the surface of the roller 103, and the second end 111 abuts against the pressure mechanism 102. The pressure mechanism 102 applies downward pressure to the second end 111. The first end 113 is higher than the fulcrum 112, and the fulcrum 112 is higher than the second end 111. As a result, the dry pine wood strip 109, the pressure mechanism 102, and the translation mechanism 110 form a lever structure. The pressure mechanism 102 applies downward pressure to the second end 111. Based on the lever principle, the first end 113 applies upward pressure to the portion abutting against the surface of the roller 103. In this way, Figure 1 As shown, the entire translation mechanism 110 and the pressure mechanism 102 are installed on the side of the roller 103. The lever principle can be used to apply force to one end of the dry pine wood strip 109 so that the dry pine wood strip 109 can contact and press the surface of the roller 103 for cleaning. The device does not need to be installed directly under the roller 103, which is beneficial to the operation and maintenance of the device during use.

[0040] In the prior art, the roller cleaning device uses spring sheets and graphite bricks for cleaning. The spring sheet is inserted into the limit groove 106 just below the roller 103, and a graphite strip is placed on it. When cleaning is required, the graphite strip is raised and contacted with the roller 103 by external force, and the solid matter on the surface of the roller 103 is wiped off for overall cleaning. When local cleaning is required, the effect is not good, and as the use time increases, the graphite strip is worn and powdered, and the wiping effect is unstable and difficult to control. The present invention uses the principle of lever, so that only one end of the dry pine wood strip 109 acts on the surface of the roller 103, and the local cleaning effect is better. And because the device is located on the side of the roller 103, it is more convenient to replace the dry pine wood strip 109.

[0042] refer to Figure 3 In some embodiments of the present invention, the support frame 105 can be raised and lowered, so that the height of the support frame 105 can be adjusted, thereby adjusting the height of the fulcrum portion 112 placed on the pallet 104 to meet the requirements for the placement height of the dry pine wood strips 109 in different environments.

[0043] refer to Figure 3 In some embodiments of the present invention, the support frame 105 is a scissor-type lifting mechanism, which has a simple and clear structure, is safe and efficient, and can well lift the dry pine wood strips 109.

[0044] It should be noted that the support frame 105 can also be a common lifting structure such as a spiral lifting mechanism, a telescopic lifting mechanism, etc., which is used to lift the dry pine wood strips 109.

[0045] refer to Figure 1 and Figure 4 In some embodiments of the present invention, the device is provided with a limiting groove 106, which is placed directly below the roller 103, the axis of the roller 103, the center line of the limiting groove 106 along the grooving direction, and the center line of the track 108 along the moving direction are located in the same plane, the dry pine wood strip 109 has a contact surface with the limiting groove 106, and there are groove walls on both sides of the limiting groove 106, and the groove walls are against the dry pine wood strip 109 to limit the movement of the dry pine wood strip 109 in the direction perpendicular to the groove wall; in this way, since the dry pine wood strip 109 is moved in the working process 9 is subjected to multiple forces, and the groove walls on both sides of the limiting groove 106 can effectively reduce the swing of the dry pine wood strip 109 in the direction perpendicular to the groove wall, thereby improving the stability of the working process, and the three lines are located in the same plane so that the contact surface between the dry pine wood strip 109 and the roller 103 can be located at the bottom of the roller 103, and the friction force of the dry pine wood strip 109 on the roller 103 is perpendicular to the pressure generated on the roller 103, thereby reducing the influence of the components of the two forces in each other's directions, improving the working efficiency, and reducing the swing of the dry pine wood strip.
