Description

Technical Field

[0001] This invention relates to an automatic lid-opening device, and more particularly to an automatic lid-opening device for a rolled sample bar insulation box, belonging to the field of automation device technology. Background Technology

[0002] Currently, rolled sample bars often require insulation treatment at different temperature environments during production, inspection, and transportation to ensure the accuracy of test results. Existing insulation boxes mostly use a manual flip-top method. Since the rolled sample bars are in a red-hot state, with temperatures reaching hundreds of degrees Celsius, manual operation is not only labor-intensive and inefficient but also carries significant risks. Furthermore, the instability of manual flip-top operation can lead to deformation of the insulation box lid, resulting in insufficient sealing and affecting the insulation effect. There is an urgent need for an automatic flip-top device for insulation boxes to improve ease of use and ensure insulation effectiveness. Summary of the Invention

[0003] Based on the above reasons, this invention designs an automatic flipping device for a rolling sample bar insulation box driven by a rod mechanism, which is used to automatically flip the insulation box of the rolling sample bar at the sampling station of the bar rolling production line.

The device includes a fixed hinge motor 1, a dual output shaft reducer 2, a first connecting rod 3, a power mounting base 4, a movable hinge motor 5, a reducer 6, a clutch 7, a joint shaft 8, a second connecting rod 9, an electromagnet mounting base 10, and an electromagnet 11.

[0005] The fixed hinge motor 1 and the movable hinge motor 5 are the power sources for the flipping action of the entire device. The motor shaft of the fixed hinge motor 1 is connected to the input shaft hole of the dual-output shaft reducer 2, and the two output shafts of the dual-output shaft reducer 2 are respectively connected to the two first connecting rods 3.

The output shaft of the reducer 6 is fixedly installed in the input shaft hole of the clutch 7. The right end of the joint shaft 8 is installed in the output shaft hole of the clutch 7. The two second connecting rods 9 are arranged inside the two first connecting rods 3. Both second links 9 and both first links 3 are connected to the joint shaft 8 through shaft holes. The two first links 3 and the joint shaft 8 are hinged together by bearings, while the two second links 9 and the joint shaft 8 are hinged together by keys. The ends of the two second links 9 are hinged together with the electromagnet mounting base 10. The electromagnet 11 is fixedly mounted on the lower surface of the electromagnet mounting base 10.

[0006] The beneficial technical effects of the automatic lid-opening device for the rolling sample bar insulation box of the present invention include:

[0007] (1) By energizing and de-energizing the clutch, the joint can switch between active joint and passive compliant joint, making the flip-top device more adaptable to the size and placement error of different insulated boxes, and making the flip-top action more stable and smooth.

[0014] An insulated box is installed at the bar sampling station of the bar rolling production line, and the automatic flipping device of the rolled bar insulated box of the present invention is used to perform the automatic flipping operation.

[0015] The automatic flip-top device for the insulation box of rolled sample bars includes a fixed hinge motor 1, a dual output shaft reducer 2, a first connecting rod 3, a power mounting base 4, a movable hinge motor 5, a reducer 6, a clutch 7, a joint shaft 8, a second connecting rod 9, an electromagnet mounting base 10, and an electromagnet 11.

[0016] The fixed hinge motor 1 and the movable hinge motor 5 are the power sources for the flipping action of the entire device. The motor shaft of the fixed hinge motor 1 is connected to the input shaft hole of the dual-output shaft reducer 2, and the two output shafts of the dual-output shaft reducer 2 are respectively connected to the two first connecting rods 3. The dual-output shaft reducer 2 is a worm gear reducer. The right side of the end of the right first connecting rod 3 is fixedly mounted on the power mounting base 4. The power mounting base 4 is U-shaped. The movable hinge motor 5, reducer 6, clutch 7, and joint shaft 8 are arranged coaxially from right to left. The clutch 7 is an electromagnetic clutch.

The ends of the two second links 9 are hinged together with the electromagnet mounting base 10. The electromagnet 11 is fixedly mounted on the lower surface of the electromagnet mounting base 10.

[0017] The specific operating steps of the automatic flip-top lid of the rolling sample bar insulation box of the present invention are as follows:

[0018] (1) On-site installation

[0019] At the bar sampling station of the bar rolling production line, the automatic flip-top device of the rolled sample bar insulation box is installed behind the insulation box with bolts (the insulation box cover is open, and the opening faces forward), and a certain distance is maintained between the insulation box and the insulation box so that the insulation box is within the working range of the automatic flip-top device.

[0020] (2) Single flip-top operation process

[0021] When it is necessary to take out and put in the rolled sample bar, the operation steps for opening and closing the insulated box are as follows:

[0022] (1) When the clutch 7 is energized, the joint shaft 8 rotates actively under the drive of the movable hinge motor 5 and the reducer 6, which drives the second connecting rod 9 to rotate clockwise, so that the second connecting rod 9 opens and the movable hinge motor 5 stops rotating;

[0023] (2) The fixed hinge motor 1 and the double output shaft reducer 2 drive the first connecting rod 3 to rotate counterclockwise, so that the electromagnet 11 moves to the top of the heat preservation box cover;

[0024] (3) When the clutch 7 is de-energized, the joint shaft 8 switches to the free state, and the electromagnet 11 adheres to the insulated box cover under the action of gravity. When the electromagnet 11 is energized, it grips the insulated box cover.

[0025] (4) Fixed hinge motor 1 and double output shaft reducer 2 drive the first connecting rod 3 to rotate clockwise, and the second connecting rod 9 rotates freely around the joint shaft 8 to open the heat preservation box cover and wait for the rolling sample bar to be packed.

[0026] (5) After the rolling sample bar is packed, the fixed hinge motor 1 and the double output shaft reducer 2 drive the first connecting rod 3 to rotate counterclockwise, and the second connecting rod 9 rotates freely around the joint shaft 8 to close the heat preservation box cover.

[0027] (6) When the electromagnet 11 is de-energized, the electromagnet releases the heat preservation box cover, the clutch 7 is energized, and the joint shaft 8 rotates actively under the drive of the movable hinge motor 5 and the reducer 6, which drives the second connecting rod 9 to rotate clockwise, so that the electromagnet 11 is disengaged from the heat preservation box cover, and the movable hinge motor 5 stops rotating.

[0028] (7) The fixed hinge motor 1 and the dual output shaft reducer 2 drive the first connecting rod 3 to rotate clockwise, so that the first connecting rod 3 reaches the initial position in the waiting operation state;

[0029] (9) The joint shaft 8 rotates actively under the drive of the movable hinge motor 5 and the reducer 6, which drives the second connecting rod 9 to rotate counterclockwise, and the electromagnet 11 reaches above the dual output shaft reducer 2.

[0030] (10) When the clutch 7 is de-energized, the joint shaft 8 is switched to the free state, and the electromagnet 11 is placed on top of the dual output shaft reducer 2 under the action of gravity. The entire device is in a waiting state.

[0031] This completes a single opening process of the automatic opening device for the rolling sample bar insulation box. To retrieve or place sample bars as needed, repeat the above steps.
