Description

Technical Field

[0001] The utility model belongs to the technical field of glass production equipment. Specifically, the utility model relates to a control device for a tin bath edge damper. Background Art

[0002] At present, in the production of float glass, edge dampers are installed in the tin bath to ensure that the glass plate is pulled outward from the center of the tin bath. The edge dampers are arranged at appropriate positions on both sides inside the tin bath to prevent the glass ribbon from swinging and deviating. Under normal circumstances, one side blocks the glass ribbon, and there is an appropriate distance between the other side and the glass ribbon.

[0003] After the width of the glass ribbon changes, it is required to adjust the position of the edge damper. The existing operation method is to manually push or pull the edge damper on-site. This operation method is not stable enough, and the distance between the edge damper and the glass ribbon cannot be seen during operation, resulting in inaccurate position control of the edge damper. Moreover, it requires the assistance of multiple people to complete the requirements, increasing the workload, being prone to misoperation, having instability, and misoperation will cause output loss.

[0019] The following is a more detailed description of the specific embodiments of the present utility model with reference to the drawings, aiming to help those skilled in the art have a more complete, accurate, and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0020] It should be noted that in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in terms of structure and / or function, nor do they represent the execution order, but are only for the convenience of description.

[0021] As Figure 1As shown in the figure, the utility model provides a control device for a tin bath edge damper, which includes an image collector for collecting images inside the tin bath, a connecting pipe 15 connected to the edge damper 3, a fixture 4 arranged on the connecting pipe 15, and an adjusting mechanism for controlling the linear movement of the edge damper 3. The adjusting mechanism includes a motor reducer 8, a first transmission mechanism connected to the motor reducer 8, a second transmission mechanism connected to the first transmission mechanism, and a limit switch 7 for limiting positions. The second transmission mechanism is connected to the fixture 4.

[0022] Specifically, as Figure 1 shown, an edge seal 14 is arranged on the tin bath, and a guide rail channel steel 5 is arranged on the edge seal 14. The motor reducer 8 is fixedly installed at one end of the guide rail channel steel 5. The first transmission mechanism is a chain transmission mechanism, and the second transmission mechanism is a lead screw nut mechanism. The driving sprocket of the first transmission mechanism is connected to the output shaft of the motor reducer 8, and the driven sprocket of the first transmission mechanism is connected to the lead screw of the lead screw nut mechanism. The lead screw is installed on the guide rail channel steel 5 through two bearing seats 6, and the guide rail channel steel 5 plays a guiding role for the nut. Two limit switches 7 are arranged. The nut of the lead screw nut mechanism is connected to the fixture 4 and the nut is located between the two limit switches 7, playing a role of limit protection.

[0023] Preferably, the nut of the lead screw nut mechanism is a trapezoidal nut 11, and the lead screw of the lead screw nut mechanism is a trapezoidal screw 10. The lead screw nut mechanism with this structure has good self-locking property, high precision, and good stability, which helps to improve the accuracy of the position adjustment of the edge damper 3.

[0024] The image collector is an endoscope. The endoscope is arranged inside the tin bath and is electrically connected to the control unit. The driving motor is controlled by the control unit. The image collector is used to collect the image of the glass ribbon inside the tin bath and send the collection result to the control unit. The control unit controls the display in the central control room to display the image. The operator in the central control room can observe the plate width position of the tin bath glass ribbon according to the endoscope image, and then can control the adjusting mechanism to accurately adjust the position of the edge damper 3, which can accurately control the position of the edge damper 3. There is no need for personnel to operate on site, which can greatly reduce the workload of employees. In addition, the motor reducer 8 is used to provide driving force, so that the movement of the edge damper 3 is relatively stable and there will be no losses caused by manual misoperation.

[0025] As Figure 1 and Figure 2As shown in the figure, one end of the connecting pipe 15 is fixedly connected to the edge stopper 3. A through hole for the connecting pipe 15 to pass through is provided on the side seal 14. The fixture 4 includes an upper clamping plate 401, a lower clamping plate 402, and a fastener connecting the upper clamping plate 401 and the lower clamping plate 402. The connecting pipe 15 is located between the upper clamping plate 401 and the lower clamping plate 402, and the lower clamping plate 402 is connected to the nut of the second transmission mechanism. The upper clamping plate 401 is located above the connecting pipe 15, and the lower clamping plate 402 is located below the connecting pipe 15. The upper clamping plate 401 and the lower clamping plate 402 are parallel to each other. The fastener includes a locking bolt 403 and a locking nut. Through holes for the locking bolt 403 to pass through are provided on the upper clamping plate 401 and the lower clamping plate 402. The locking bolt 403 is vertically arranged, and the lower end of the locking bolt 403 is fixedly connected to the nut of the second transmission mechanism through two locking nuts. The locking bolt 403 is fixedly connected to the lower clamping plate 402 through two locking nuts. These two locking nuts are located above and below the lower clamping plate 402, and the two locking nuts clamp the lower clamping plate 402. The upper end of the locking bolt 403 clamps the upper clamping plate 401 through the cooperation of a locking nut and a locking handle 16. The locking nut is located below the upper clamping plate 401, and the locking handle 16 is located above the upper clamping plate 401. The locking handle 16 and the locking nut are threadedly connected to the locking bolt 403. When a power failure occurs and it is necessary to manually adjust the position of the edge stopper 3, the locking handle 16 and the locking nut can be loosened, and the connecting pipe 15 can be moved. The connecting pipe 15 drives the edge stopper 3 to move, and the position of the edge stopper 3 can be adjusted, so as to quickly complete the switching from electric operation to manual operation and restore pure manual operation.

[0026] Preferably, multiple fasteners are provided, and all the fasteners are distributed on the opposite sides of the connecting pipe 15 to ensure reliable fixation.

[0027] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings.
