The design of synchronous adjustment reduces manual errors, and ensures the stability and durability of the measurement system through the acting force of the spring.

Description

Technical Field

[0001] The invention relates to the technical field of glass production measurement, in particular to float glass production equipment and process. Background Art

[0002] In the existing float glass production process, the thickness and width of the glass are important parameters to ensure product quality, which directly affect the uniformity and stability of the finished product. The commonly used method for measuring glass thickness is a mechanical contact sensor. This type of sensor mainly relies on laminating with the glass surface and directly contacting the glass surface to obtain precision data. However, although this measurement method was relatively common in the early days, with the continuous advancement of production technology, its limitations have gradually emerged, especially in the context of faster production line operation speed and higher glass quality requirements, the traditional mechanical contact measurement method has gradually failed to meet the needs. First of all, the working principle of the mechanical contact sensor relies on physical contact, which measures the thickness by closely contacting the glass surface. However, during the cooling and forming process of the glass, due to the influence of thermal stress, the surface often has slight convexities, concave or other irregular deformations. This unevenness of the glass surface will cause large errors in the measurement process of the contact sensor, especially in the cooling stage of the glass, where tiny surface convexities or concave convexities will cause deviations in the sensor's measurement values. In addition, during the glass transmission process, the continuous friction between the mechanical sensor and the glass surface will cause slight scratches on the glass surface, further affecting the finish and transparency of the finished product.

An inclined sliding groove 413 is fixed at the top of the recovery pipe 404, and the lower end of the sliding groove 413 is arranged above the discharge chute 301.

[0025] The working principle of a float glass production device disclosed in the present invention is as follows: raw materials are poured into a feed chute 301, and then a feed control motor 305 is started. The feed control motor 305 drives a feed hole 304 to rotate to a position aligned with a feed channel 302, so that the raw materials in the feed chute 301 pass through the feed hole 304 into a melting furnace 306 (a plurality of vibration motors are arranged on the inner wall of the feed chute 301), and the melting furnace 306 heats the glass raw materials to form molten glass liquid. The molten glass liquid flows into the float tin bath 501 through the liquid flow port 310 (the flow rate of the molten glass liquid at the liquid flow port 310 can be controlled by extending and retracting the telescopic rod of the current regulating electric cylinder 313), and the tin liquid surface inside the float tin bath 501 is spread out flat, wherein the temperature of the tin liquid near the end of the melting furnace 306 (molten glass flow port) is higher than the temperature near the end of the annealing furnace 601 (drawing end), the purpose of which is to maintain the good fluidity of the molten glass at high temperature, so that it can be evenly spread on the tin liquid surface, avoiding irregular flow or surface defects, the temperature of the middle area gradually decreases, ensuring that the glass ribbon maintains a flat and stable thickness during the gradual cooling process, and at the same time controlling the cooling rate of the glass liquid to avoid thermal stress concentration, the temperature of the drawing end area is further reduced, so that the glass has an appropriate cooling speed before entering the annealing furnace 601, in preparation for the subsequent annealing process, and there is a slightly positive pressure of nitrogen gas inside the float tin bath 501.

[0026] The annealed glass will move to the measuring assembly. The problem solved by the measuring assembly is that the surface of the glass is not absolutely flat during the cooling or production process, and the rotating measuring roller is attached to the glass surface for measurement. This will result in a gap between the lower surface of the glass and the conveying roller 110 if the glass surface is convex. At this time, the measured glass thickness will be too large, which will cause measurement errors. The light emitted by the laser 109 in the measuring assembly will be tilted toward the glass and pass through the glass, and then irradiate the light sensor 108, so that the light sensor 108 generates a corresponding electrical signal (the light sensor 108 generally uses a high-pixel camera sensor, and the light emitted by the laser 109 will generate an electrical signal at the corresponding position of the camera sensor, that is, the corresponding pixel position. Since the pixel position is fixed, it can be used as a scale); when the light enters the interior of the glass, it will be refracted (by controlling the telescopic rod of the adjusting electric cylinder 106, and then driving the adjusting swing arm 104 to swing, adjusting the swing arm The arm 104 drives the laser bracket 105 to swing, and the laser bracket 105 drives all the lasers 109 to swing, thereby adjusting the angle between the light emitted by the laser 109 and the glass to prevent the total reflection of the light). Then, the light propagates in the glass for a distance and then is projected from the glass to the light sensor 108. During this process, the light on the upper and lower sides of the glass will be offset, and the offset can be detected by the light sensor 108. The offset is proportional to the thickness of the glass. The thicker the glass, the longer the propagation path of the light after it enters the glass, resulting in a larger offset. The measuring component can realize non-contact detection of the glass thickness, and there is no need to consider the flatness of the glass surface, and the thickness of the glass can be directly measured.

[0027] The glass with measured thickness will be cut on the side, and then the glass will be cut into glass strips of equal width, and then the width of the glass will be detected by the auxiliary components. The side of the glass will be against the measuring roller 202, and the two measuring rollers 202 will drive the synchronous rod 204 to move linearly through the two measuring roller movable rods 203. This is because the measuring sliding rod 207 is slidably installed on the bow frame 201 through the measuring sliding rod bracket 206, so the movement mode of pushing the synchronous rod 204 is determined, and the set extrusion spring 205 provides a reverse force, so that the two measuring rollers 202 can always keep close contact with the side of the glass. The displacement of the measuring sliding rod 207 compared to the measuring sliding rod bracket 206 can be detected by the grating ruler, so as to measure the width of the glass strip. Then the glass is cut horizontally, so that the long glass strip is cut into the required length.

[0028] The cut glass fragments will be transmitted to the recovery barrel 401 through the feeding conveyor belt 412, and the crushing control motor 408 will be started. The output shaft of the crushing control motor 408 will drive the driving gear 409 to rotate, and the driving gear 409 will drive the driven gear 410 to rotate. The rotation of the driven gear 410 will drive the crushing blade rotating sleeve 407 to rotate, and the rotation of the crushing blade rotating sleeve 407 will drive all the crushing blades 406 to rotate. The crushing blades 406 will break the larger glass fragments into small pieces, and then fall to the bottom of the recovery barrel 401 through the partition screen 405. At this time, the recovery control motor 403 is started, and the output shaft of the recovery control motor 403 drives the recovery screw 402 to rotate. The recovery screw 402 rotates to transmit the glass fragments at the bottom of the recovery barrel 401 along the recovery pipe 404 to the top of the recovery pipe 404, and then slide down the sliding groove 413 to the inside of the lower feeding trough 301 again, so as to realize the recovery of glass fragments.
