Description

Technical Field

[0001] This invention specifically relates to a quick-opening device for traction rollers used to handle broken glass sheets, belonging to the technical field of overflow glass production equipment. Background Technology

[0002] In overflow glass production, changes in the production environment, such as pressure differentials or temperature variations within the furnace, can cause glass to crack or break within the furnace. In the event of a break, the traction rollers must be opened quickly to allow the softened glass to flow down; otherwise, the softened glass will accumulate on top of the traction rollers, leading to a blockage. Blockages are considered major accidents in the glass industry, and in severe cases, can render the production line unusable. Therefore, quickly opening the traction rollers to allow the softened glass to flow down as soon as possible after a break is crucial for ensuring the safe operation of the equipment. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a quick-opening device for traction rollers to handle broken plates, aiming to quickly open the traction rollers after a plate breakage occurs.

[0004] The technical solution of the present invention is as follows: A first aspect of the present invention provides a quick-opening device for a traction roller for handling broken plates, comprising, A base plate, on which guide rails are fixedly mounted; The left and right traction roller systems are identical in structure and are arranged parallel to each other on the base plate. Each traction roller system includes a slider, on which a traction roller motor is fixedly mounted. A traction roller is connected to the output shaft of the traction roller motor, which drives the traction roller to rotate. The two parallel traction rollers can clamp and move the glass. The slider cooperates with a guide rail, allowing the traction roller system to move along the guide rail. The direction of movement of the traction roller system along the guide rail is perpendicular to the axial direction of the traction roller. The left and right connecting parts have the same structure. Each connecting part includes a first connecting rod and a second connecting rod arranged in parallel and spaced apart. One end of the first and second connecting rods is fixedly connected to the slider. The other end of the first and second connecting rods is connected to one end of the anti-torsion adjusting screw through a union. The other ends of the two anti-torsion adjusting screws are respectively threaded to both ends of the third connecting rod. The middle part of the third connecting rod is connected to one end of the fourth connecting rod. A left drive unit and a right drive unit are provided, with the output end of the drive unit connected to the other end of the fourth link; the left drive unit drives the left traction roller system to move along the guide rail through the left connector, and the right drive unit drives the right traction roller system to move along the guide rail through the right connector; a forward and reverse thread telescopic adjustment screw is provided on the fourth link, and locking nuts are provided at both ends of the forward and reverse thread telescopic adjustment screw.

[0005] Furthermore, the guide rail is a slide bar, and a groove is provided below the slider, the groove cooperating with the slide bar.

[0006] Furthermore, the driving device is a cylinder, and the output end of the cylinder is connected to the fourth link of the connecting member.

[0007] The second invention provides a broken glass processing system in overflow glass production, employing two sets of the traction roller quick-opening devices described in the first aspect. These two sets of traction roller quick-opening devices are installed at both ends of an annealing furnace, respectively supporting both sides of the glass. Five photoelectric switches are installed at the bottom of the annealing furnace along the glass width direction. The photoelectric switches and their driving devices are electrically connected to a control system. The operating method of the processing system is as follows: Under normal conditions, the traction roller rotates inward to clamp the glass and pulls the glass downward. The glass is conveyed downward through five photoelectric switches in a complete form or with only cracks. None of the five photoelectric switches output signals, and the quick-opening device does not activate. When there are two or fewer photoelectric switch output signals, it indicates that a small area of ​​the glass has broken. At this time, the control system issues an alarm signal to remind manual handling, and the quick-opening device does not activate. When three or more photoelectric switches output signals, it indicates that the glass has broken over a large area, i.e., the glass is broken. At this time, the control system simultaneously controls the two sets of quick-opening devices to operate. The left and right drive devices in each quick-opening device operate to separate the traction rollers.

[0008] This invention performs real-time online monitoring of the glass in the overflow glass production process. The control system automatically determines whether a glass breakage has occurred. Once a breakage is detected, the gap between the two traction rollers opens within milliseconds, allowing the softened glass to flow down as quickly as possible. This prevents the softened glass from accumulating on the traction rollers for an extended period and causing blockages. In contrast, existing technologies require manual monitoring of the glass conveyor belt and manual opening of the traction rollers, taking approximately 20 minutes to process. Compared to existing solutions, this invention significantly reduces the occurrence of glass breakage and blockages due to its extremely rapid response to breakage incidents and the greatly shortened traction roller opening time.

Detailed Implementation

[0014] The present invention will now be clearly and completely described with reference to the accompanying drawings.

[0015] like Figure 1-2 As shown, a quick-opening device for traction rollers used to handle broken sheets in overflow glass production includes a base plate, a slide bar, a slider, a left traction roller system, a right traction roller system, a left connector, a right connector, a left drive device, and a right drive device.

[0016] Specifically, a first outer slide rod 3, a second outer slide rod 12, a first inner slide rod 8, and a second inner slide rod 17 are fixedly installed on the base plate 25. These outer and inner slide rods all serve as linear guide rails. A left traction roller system and a right traction roller system are installed on the slide rods. The left and right traction roller systems have the same structure and are arranged parallel to each other on the base plate 25. Each traction roller system includes a slider 26, with a groove below the slider 26. The groove cooperates with the slide rod to allow the slider to slide along the slide rod. Traction roller motors, such as a left traction roller motor 4 and a right traction roller motor 13, are fixedly installed on the sliders. Traction rollers, namely a left traction roller 9 and a right traction roller 18, are connected to the output shaft of the traction roller motors. The two parallel traction rollers can clamp the glass. When the traction roller motor drives the traction rollers to rotate inward, it can pull the glass to move. The slider cooperates with the slide rod to allow the traction roller system to move along the slide rod. The direction of movement of the traction roller system along the slide rod is perpendicular to the axis of the traction roller.

[0017] The left and right connecting parts have the same structure; taking the left connecting part as an example, it includes a first connecting rod 27, a second connecting rod 28, a third connecting rod 29, and a fourth connecting rod 30; wherein the first connecting rod 27 and the second connecting rod 28 are arranged in parallel and spaced apart, one end of the first connecting rod 27 and the second connecting rod 28 are fixedly connected to the slider 26, and the other end of the first connecting rod 27 and the second connecting rod 28 are connected to one end of the left anti-torsion adjusting screw 2 through the left movable joint 7. The other ends of the two left anti-torsion adjusting screws are respectively threaded to both ends of the third connecting rod 29, and the middle part of the third connecting rod 29 is connected to one end of the fourth connecting rod 30.

[0018] The left and right drive devices have the same structure. The drive device is preferably a cylinder, and the output end of the cylinder is connected to the connector. Specifically, the output end of the left cylinder 1 is connected to the other end of the fourth connecting rod 30. The left cylinder 1 drives the left traction roller system to move along the first outer slide rod 3 and the first inner slide rod 8 through the left connector. The right cylinder drives the right traction roller system to move along the second outer slide rod 12 and the second inner slide rod 17 through the right connector. A left forward and reverse thread telescopic adjustment screw 6 is provided on the fourth connecting rod 30, and locking nuts 5 are provided at both ends of the left forward and reverse thread telescopic adjustment screw 6.

[0019] The uses of the main components used in this invention, such as cylinders, photoelectric switches, telescopic adjustable screws for forward and reverse threads, locking nuts, anti-torsion adjusting screws, slide rods, traction rollers, traction roller motors, and swivel joints, are explained below.

[0020] Cylinders: One cylinder is installed on each of the left and right sets of connecting parts and the traction roller system. During normal production, the cylinder rod extends and, after being transmitted through the connecting parts, pushes into the traction roller system, causing the two traction rollers to hold the glass and rotate. When the control system detects a broken plate fault on site, the left / right cylinders retract and pull, which can quickly open the gap between the two traction rollers, allowing the glass strip to flow down.

[0021] Adjustable retractable screw with forward and reverse threads: One screw is installed on each of the left and right connecting parts. After the cylinder extends normally, the gap between the two traction rollers can be finely adjusted through this device to ensure that the force applied by the traction rollers to the glass is moderate. The retractable retractable screw with forward and reverse threads is connected to the cylinder on the outside and to the traction roller system on the inside.

[0022] The locking nuts are located at both ends of each telescopic adjustable screw for the forward and reverse threads. After the traction roller gap is adjusted, these nuts need to be used to lock the telescopic adjustable screw for the forward and reverse threads to ensure that the traction roller gap does not change due to equipment vibration.

[0023] The anti-torsion adjusting screw is used to adjust the extension length of the traction roller system when the cylinder pulls the traction roller motor and causes oblique pulling on the slide rail. This allows the traction roller system to move smoothly in a straight line along the slide rail under the action of the cylinder pulling force.

[0024] The traction roller is used to hold the glass and pull it downwards.

[0025] The traction roller motor is the power unit for rotating the traction roller. This motor is a servo motor, and it operates under the control of a servo controller. Figure 3 The four motors in the machine rotate at the same speed.

[0026] The swivel joint acts as a rotary connection in its original position when the anti-torsion adjusting screw is rotated.

[0027] like Figure 3 As shown, a broken glass processing system in overflow glass production includes an annealing furnace, two sets of the aforementioned quick-opening traction roller devices, five photoelectric switches, and a control system, etc., wherein the annealing furnace and the control system are not shown in the figure. The two sets of quick-opening traction roller devices are installed at both ends of the annealing furnace, respectively supporting both sides of the glass 24; five photoelectric switches 19, 20, 21, 22, and 23 are arranged at the bottom of the annealing furnace along the width direction of the glass. The five photoelectric switches, four traction roller motors, and solenoid valves of two control cylinders are all electrically connected to the control system.

[0028] like Figure 4 As shown, the working method of the broken glass handling system in overflow glass production is as follows: First, debug the equipment, start the traction roller motor to rotate, and adjust the anti-torsion adjusting screw to ensure that the slider and the slide bar slide smoothly and avoid twisting. Then, start the left and right cylinders to push forward, so that the traction roller holds the glass. Next, adjust the forward and reverse telescopic adjusting screw to make the traction roller hold the glass with appropriate force. After the equipment is debugged, it can be put into normal production. Under normal conditions, the traction roller motor drives the traction roller to rotate inward to clamp the glass and pull the glass downward. The glass is conveyed downward through five photoelectric switches in a complete form or with only cracks. At this time, none of the five photoelectric switches output signals and the quick-opening device does not operate. When there are two or fewer photoelectric switch output signals, it indicates that a small area of ​​the glass has broken. At this time, the control system issues an alarm signal to remind manual handling, and the quick-opening device does not activate. When three or more photoelectric switches output signals, it indicates that the glass has broken over a large area, i.e., the glass is broken. At this time, the control system simultaneously controls the two sets of quick-opening devices to operate. The left and right cylinders in each quick-opening device operate simultaneously, driving the traction roller to separate, so that the softened glass from above can flow down smoothly, avoiding the accumulation of softened glass on the traction roller for a long time, which could lead to a blockage accident.
