Description

Technical Field

[0001] The invention relates to the technical field of hollow glass processing and manufacturing, and in particular to a lifting device used for hollow glass processing and manufacturing. Background Art

[0002] The current insulating glass lamination and pressing processes are generally divided into two types. One is the external lamination mode, that is, the insulating glass is pre-assembled into the required insulating glass product structure before entering the plate press, and then sent to the plate press to press and bond the insulating glass; the other is the internal lamination mode, that is, the insulating glass is formed and pressed inside the plate press, which requires the plate press to have a lifting device to lift the glass off the conveying roller. The external lamination mode requires the pre-lamination of the insulating glass, but due to the glass deceleration and stop positioning, the constraints of the external lamination conveying guide rod and other structural requirements, and the pre-formed insulating glass of the external lamination is not effectively bonded. Due to the limitation of vertical transmission, the pre-formation of large and small pieces of insulating glass (flash insulating glass) cannot be completed. The internal lamination process with an internal bottom edge lifting device provides a solution for the online inflation of large and small pieces of flash glass and insulating glass. (Note: Inert gas (AR argon) is filled in the hollow glass cavity to improve the thermal insulation performance of the hollow glass and reduce the thermal deformation of the hollow glass caused by temperature changes.) The in-board laminating machine can realize unequal-sided hollow glass in the length direction of the hollow glass by setting a movable limit arm to position the glass, that is, single-sided flash, double-sided flash, and large and small pieces of hollow glass. Because the in-board laminating machine is not restricted by the movable guide rod structure, the upper edge of the solid glass does not need to be equal pieces to allow for glass height differences, and single-sided flash, double-sided flash, and three-sided flash on the top, left, and right can be achieved. The above is the current development status of the in-board laminating machine and the in-board inflator. In the face of the demand for four-sided large and small pieces of hollow glass in the hollow glass application market, it is urgently necessary to develop a bottom edge lifting and positioning device that can be accurately positioned for the in-board laminating machine or the in-board inflator to solve the problem that four-sided large and small pieces of hollow glass cannot be produced online.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0010] Furthermore, the initial zero point position of the sheet support buffer pad is located below the conveying roller at the bottom of the rear pressure plate.

[0011] Furthermore, the ball screw is the output shaft of the reducer, and the output direction of the reducer is consistent with the lifting direction.

[0012] Furthermore, the two reducers are both fixedly connected to the lifting device fixing seat, and the two reducers are driven by the servo motor.

[0013] Furthermore, the sensor induction block is fixedly connected to the support beam, and the upper limit sensor and the lower limit sensor are both fixedly connected to the lifting device fixing seat.

[0029] The device is installed at the bottom end of the plate press 19 (or hollow glass inflator), and at the same time, an avoidance groove 24 is opened at the bottom end of the front pressure plate 20 and the rear pressure plate 21 corresponding to the position of the vertical lifting bracket 6 to provide space for the lifting movement. At the same time, the initial zero point position of the buffer pad is set as the reference plane for the lifting movement, and the composition information of the pre-produced four-sided large and small pieces of glass products is conveyed to the PLC control module of the equipment in advance (the PLC can calculate the overlap difference between the corresponding sides of the large and small pieces of glass through the data information of the four sides of the large and small pieces of glass, thereby controlling the movement of the servo motor 12 and the limit arm 23, and accurately transporting the large and small pieces of glass to the target position).
