Description

Technical Field

[0001] This invention relates to the field of carrier glass manufacturing and processing, specifically to a centering and angle adjustment device for forming equipment and its automatic control system. Background Technology

[0002] In the glass forming process, it is difficult to directly measure whether the tip of the forming module is perpendicular to the ground plane using tools. The perpendicularity of the forming module tip to the horizontal plane plays a decisive role in the glass forming process. Furthermore, during the forming module production, the tilt angle of the entire forming equipment needs to be adjusted.

[0003] Existing technologies involve cumbersome adjustment procedures that cannot be performed simultaneously and are not conducive to calculation. In actual adjustment, there may be angular deviations that are difficult to detect or observe, resulting in significant discrepancies from the ideal values. In subsequent equipment maintenance, the repositioning process of the molding module tip is complex and not easy to measure directly, and traditional installation processes are time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the above-mentioned background technology, and to propose a centering and angle adjustment device for molding equipment and its automatic control system.

[0005] To achieve the above objectives, the invention provides the following technical solution:

[0006] A centering and angle adjustment device for molding equipment includes a screw jack, coupling, reducer, servo motor, connecting beam, moving seat, flat roller, fixed base, V-roller, connecting fork, pin, suspension beam, drive shaft, servo motor, gear, rack, offset measuring ruler and offset pointer.

[0007] The flat roller and the V-shaped roller are fixedly assembled on the movable seat by keys and bolts. There are four sets of movable seats and four sets of connecting crossbeams. The four sets of movable seats and four sets of connecting crossbeams are connected by bolts and keys to form a movable whole.

[0008] The servo motor and reducer are connected to the screw jack via a coupling. The servo motor is electrically connected to the screw jack and can convert the displacement signal of the screw jack into an electrical signal value output. The screw jack is connected to the moving base via bolts.

[0009] The servo motor is fixedly mounted on the connecting beam via a connecting seat. The servo motor provides power to the equipment through gear transmission. The drive shaft is connected to the gear via a key. The rack is fixedly mounted on the fixed base with bolts.

[0010] The offset measuring ruler and the offset pointer together constitute an offset detection device;

[0011] The screw jack is connected to the suspension beam via connecting forks, pins, bolts, and lead screws.

[0012] Preferably, the offset measuring ruler is fixed to the connecting crossbeam by insulating material, and the offset pointer is fixed to the suspension beam by insulating material. It uses the principle of sliding rheostat circuit to measure the current value in the circuit to determine the offset angle direction of the surface where the offset detection device is located, and then adjusts the horizontal position of the suspension beam.

[0013] An automatic control system for a centering and angle adjustment device of a molding equipment, the specific steps of its automatic control operation are as follows:

[0014] S1. The equipment is pre-set with the screw jack lifting height comparison value as τ and the offset measuring device comparison value as β;

[0015] S2. After the overall equipment assembly is completed, the four sets of screw jacks begin to lift simultaneously, raising the suspension beam to the specified height. The lifting height of the screw jacks is converted into electrical signals by servo motors, denoted as Ah, Bh, Ch, and Dh respectively. This is considered reaching the prescribed height; other conditions are similar.

[0016] S3. After all the screw jacks have reached the set position, fix one of the screw jacks as the reference for subsequent adjustment. Here, screw jack A is fixed and the current value α in the offset detection device circuit is measured. If α < β, the height of the suspension point of jack B is raised; if α > β, the height of the suspension point of jack B is lowered. Repeat this step in the order of I-IV-II-III until the values ​​of each point are the same or the height deviation error is within 1%.

[0017] S4. If horizontal movement is required after adjustment, the suspension beam must be recalibrated to ensure it meets the requirements after the movement is completed.

[0018] S5. After the leveling adjustment is completed, when the overall angle of the molding module tip needs to be adjusted during the production process, the AB end or CD end can be raised and lowered simultaneously to quickly reach the angle required by the equipment production; when the molding module tip is restored to level, it can be quickly and accurately restored to the original position, which is simpler and more accurate than the traditional process.

[0019] Compared with existing technologies, the beneficial effects of the invention are:

[0020] 1. Facilitates centering of the molding module tip;

[0021] 2. Facilitates overall angle adjustment of the molding module during the production process, simplifying steps and improving accuracy;

[0022] 3. Facilitates equipment repositioning after subsequent maintenance, improves repositioning accuracy and speed, and simplifies positioning adjustment steps. Attached Figure Description

The four sets of movable seats 6 and the four sets of connecting crossbeams 5 are connected by bolts and keys to form a movable whole.

[0033] The servo motor 4 and the reducer 3 are connected to the screw jack 1 via the coupling 2. The servo motor 4 is electrically connected to the screw jack 1. The servo motor 4 can convert the displacement signal of the screw jack 1 into an electrical signal value output. The screw jack 1 is connected to the moving base 6 via bolts.

[0034] The servo motor 14 is fixedly mounted on the connecting beam 5 via a connecting seat. The servo motor 14 provides power to the equipment through gear transmission. The drive shaft 13 is connected to the gear 15 via a key. The rack 16 is fixedly mounted on the fixed base 8 with bolts.

[0035] The offset measuring ruler 17 and the offset pointer 18 together constitute an offset detection device;

[0036] The screw jack 1 is connected to the suspension beam 12 via a connecting fork 10, a pin 11, bolts, and a lead screw. The screw jack 1 is of type JMW.

[0037] In the above, the offset measuring ruler 17 is fixed to the connecting beam 5 by insulating material, and the offset pointer 18 is fixed to the suspension beam 12 by insulating material.

Repeat this step in the order of I-IV-II-III until the values ​​of each point are the same or the height deviation error is within 1%.

[0042] S4. If horizontal movement is required after adjustment, the suspension beam must be recalibrated to ensure it meets the requirements after the movement is completed.

[0043] S5. After the leveling adjustment is completed, when the overall angle of the molding module tip needs to be adjusted during the production process, the AB end or CD end can be raised and lowered simultaneously to quickly reach the angle required by the equipment production; when the molding module tip is restored to level, it can be quickly and accurately restored to the original position, which is simpler and more accurate than the traditional process.
