Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic glass processing equipment, specifically to a photovoltaic glass annealing kiln electric heating level adjustment device. Background Technology

[0002] Photovoltaic glass consists of glass, solar cells, film, back glass, and special metal conductors. It has a wide range of applications, such as solar smart windows, solar pavilions, photovoltaic glass building roofs, and photovoltaic glass curtain walls. It is divided into two main categories: crystalline silicon photovoltaic glass and thin-film photovoltaic glass. The former is further divided into monocrystalline silicon and polycrystalline silicon, and is commonly used as a curtain wall material.

[0003] During prolonged production, the heating wire in the electric heating system of the photovoltaic glass annealing furnace can deform, causing it to become non-parallel to the glass plate. This results in uneven heating of the glass plate, affecting the annealing quality. If the heating wire is severely tilted and too close to the glass plate, it can easily come into contact with the glass plate during operations such as plate drawing and roller washing, causing the plate to break and severely impacting output and yield.

[0004] According to announcement number CN109618424A, an electric heating hand for an annealing kiln includes a protective tube with a base fastener and a resistance wire, an electric heating hand housing, and a power connection device. The protective tube is bent into a dry-layer annular structure, with the base fastener inside. The base fastener is made of high-strength heat-resistant stainless steel, and its inner width is smaller than the inner diameter of the annular structure. There is a gap between the base fastener and the protective tube. One end of the base fastener is located inside the protective tube, and the other end is fixed to the electric heating hand housing. When the protective tube bends, the bottom of the deformed part rests against the steel strip over a large area, preventing further downward deformation. This invention provides an electric heating hand for an annealing kiln with a base fastener inside the protective tube, a leakage current circuit breaker at the tail end, and a self-locking plug and socket. The plug has a power cable, and the socket is fixed to the lower tail end of the electric heating hand. This solves the technical problems of existing electric heating hands where the protective tube deforms and short-circuits due to excessive kiln temperature, and is also difficult to repair.

[0005] As described above, in the long-term production process of photovoltaic glass annealing furnaces, the heating wire can deform, causing it to become non-parallel to the glass plate. This results in uneven heating of the glass plate, affecting the annealing quality. If the heating wire is severely tilted and too close to the glass plate, it can easily come into contact with the glass plate during operations such as plate drawing and roller washing, causing the plate to break and severely impacting output and yield. Therefore, we need to propose a horizontal adjustment device for the electric heating of photovoltaic glass annealing furnaces. Utility Model Content

[0006] The purpose of this invention is to provide a horizontal adjustment device for the electric heating of a photovoltaic glass annealing furnace. By adjusting the tilt angle of the electric heating box within the adjustment sleeve, the adjustment angle of the electric heating box drives the main body of the electric heating wire at the other end to move. After adjusting the angle of the electric heating box to keep the main body of the electric heating wire horizontal with the glass plate, the knobs at both ends are turned to move the screw within the inner cavity of the threaded sleeve, thus fixing the position of the adjusted electric heating box. This improves the uniformity of heating of the glass plate, reduces the impact on the annealing quality of the glass plate, avoids the phenomenon of the heating wire touching the glass plate and causing it to explode due to severe tilting, and reduces the impact on glass plate production and yield, thereby solving the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a photovoltaic glass annealing furnace electric heating level adjustment device, including an adjustment sleeve 1, threaded sleeves 2 are inserted and fixed on both the upper and lower sides of the adjustment sleeve 1, one end of the threaded sleeve 2 extends into the inner cavity of the adjustment sleeve 1, the inner cavity of the threaded sleeve 2 is threadedly connected to a screw 3 for adjusting the angle of the electric heating wire, one end of the screw 3 is provided with a button block 4, the inner cavity of the adjustment sleeve 1 is provided with an electric heating box 5, the two sides of the electric heating box 5 are provided with a support structure 6 for preventing the electric heating box 5 from moving out of the inner cavity of the adjustment sleeve 1, and one end of the electric heating box 5 is provided with an electric heating wire body 7;

[0024] Adjusting the tilt angle of the electric heating box 5 within the adjusting sleeve 1 causes the electric heating wire body 7 at the other end to move. By adjusting the angle of the electric heating box 5 to keep the electric heating wire body 7 horizontal with the glass plate, the knobs 4 at both ends are turned to move the screw 3 within the inner cavity of the threaded sleeve 2. This fixes the position of the adjusted electric heating box 5, thereby improving the uniformity of heating of the glass plate, reducing the impact on the annealing quality of the glass plate, preventing the heating wire from tilting too much and causing it to touch the glass plate and break, and reducing the impact on glass plate production and yield.

[0025] The bottom end of the inner cavity of the adjusting sleeve 1 is set with a beveled surface. The maximum slope of the beveled surface of the adjusting sleeve 1 is set to 40°. By adjusting the setting of the inner cavity of the adjusting sleeve 1, the maximum adjustment angle of the electric heating wire body 7 of this device is 40°.

[0026] A ball bearing 8 is provided at one end of the screw 3 away from the button block 4, and a support seat 9 is provided at the other end of the ball bearing 8. Through the cooperation between the ball bearing 8 and the support seat 9, the screw 3 can better fit against the surface of the electric heating box 5 when it comes into contact with the electric heating box 5, which increases the stability of the electric heating box 5 after it is fixed.

[0027] A protective pad 10 is bonded to the outer surface of the support base 9. The surface of the protective pad 10 is provided with anti-slip texture. The protective pad 10 is designed to prevent the support base 9 from scratching the surface of the electric heating box 5 when it comes into contact with the electric heating box 5. The anti-slip texture increases the friction between the protective pad 10 and the surface of the electric heating box 5, thereby improving the stability of the support base 9 in positioning the electric heating box 5 through the protective pad 10. The protective pad 10 is made of high temperature resistant material.

[0028] The outer surface of the button block 4 is provided with a fixing groove 11. The fixing groove 11 is set in an internal hexagonal shape. By setting the fixing groove 11, the button block 4 needs a hexagonal handle to be adjusted when it is rotated, so as to avoid the phenomenon of accidentally rotating the button block 4 after adjusting the position.

[0029] The support structure 6 includes a slider 61, which is fixedly connected to the outer wall of the electric heating box 5. The inner wall of the adjusting sleeve 1 is provided with a groove 62 that matches the slider 61. The groove 62 is arc-shaped. The slider 61 is slidably connected to the inner cavity of the groove 62. Through the cooperation of the slider 61 and the groove 62, the two sides of the electric heating box 5 are supported, preventing the electric heating box 5 from sliding out of the inner cavity of the adjusting sleeve 1 during adjustment, thus improving the stability of the electric heating box 5 during adjustment.

[0030] The inner cavity of the adjusting sleeve 1 is provided with an anti-scratch pad 12. The anti-scratch pad 12 is located at one end close to the electric heating wire body 7. The anti-scratch pad 12 is provided to prevent the other end of the adjusting sleeve 1 from scratching the surface of the electric heating box 5 during adjustment. The anti-scratch pad 12 is made of high temperature resistant material.

[0031] In practical use: When the heating wire deforms, the angle of the heating box 5 is adjusted so that the heating box 5 drives the slider 61 to slide in the groove 62, keeping the heating wire at the other end of the heating box 5 horizontal with the glass plate. Then, the bottom button 4 is turned to rotate the screw 3, which pushes the support plate through the ball bearing 8 to support the bottom of the heating box 5. Then, the top button 4 is turned to fix the top support plate to the heating box 5, thereby improving the uniformity of the glass plate heating, reducing the impact on the annealing quality of the glass plate, avoiding the phenomenon of the heating wire tilting too much and touching the glass plate, which would cause the plate to break, and reducing the impact on the glass plate production and yield.

[0032] 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.
