Description

Technical Field

[0001] The utility model relates to the technical field of turnover devices, in particular to a turnover device for producing fire doors. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with a certain degree of fire resistance, which are installed between fire compartments, evacuation stairwells, vertical shafts, etc. Fire doors usually need to be processed on both sides during the production process, such as painting and other processing. Some existing flipping devices will clamp the fixed door panel from the edge to enter the flip door panel. The clamping parts will block the surface of the door panel and affect the processing operation of the door panel. Excessive clamping can also easily damage the door panel. Utility Model Content

A through hole for the screw rod 2 to pass through is formed on the first support base 4, and a threaded hole 9 that matches the screw rod 2 is formed on the second support base 5. The second support base 5 is driven to move left and right on the groove bottom plate 1 by the forward and reverse rotation of the screw rod 2. Slide rails and polished rods and other structures can be added to facilitate the movement of the second support base 5. The upper parts of the first support base 4 and the second support base 5 are both rotatably connected with a rotating shaft 6, which extends into the support base and can be connected through a bearing. The rotating shaft 6 is confined in the support base and can rotate therein. If necessary, a motor can be added to drive the rotating shaft 6 to rotate.

The front and rear vertical rods penetrate the baffle 11 and are fixed to the sandwich plate 12. The handle is fixed between the two vertical rods. The strip hole 14 penetrates the side wall of the baffle 11. The cooperation between the strip hole 14 and the first handle 13 enables the sandwich plate 12 to only move left and right on the baffle 11, so that the baffle 11 can be extended or retracted from the baffle 11. A threaded hole 9 is provided on the center block 8. The limit screw 10 can be threadedly connected and fixed on any threaded hole 9. The head of the limit screw 10 has the same thickness as the center block 8. The door panel can be limited between them in the width direction by adjusting the distance between the two limit screws 10. The door panel can be limited between them in the thickness direction by pulling out the baffle 11.A support plate 15 is movably connected in the middle of the first support base 4 and the second support base 5. The left and right ends of the support plate 15 are both provided with limit flanges 16. The outer limit flanges 16 are provided with a second handle 17. The support plate 15 passes through the first support base 4 from left to right and can move left and right therein. The limit flanges 16 are fixed at both ends of the support plate 15 and folded downward relative to the support plate 15. The limit flanges 16 are used to prevent the support plate 15 from escaping from the support base. The second handle 17 is fixed on the limit flap to facilitate manual movement of the support plate 15. If necessary, an electric cylinder can be added to drive the support plate 15 to move. When the rotating plate 7 is horizontally facing the baffle 11, the support plate 15 can be moved under the baffle 11. The rotating plate 7 and the baffle 11 are supported by the support plate 15 to limit the rotation of the rotating plate 7.

[0011] Working principle: Rotate the rotating wheel 3 and the screw rod 2 to drive the second supporting base 5 to move left and right. Adjust the distance between the first supporting base 4 and the second supporting base 5 according to the length of the door panel, so that the distance between the left and right center blocks 8 is slightly larger than the length of the door panel. The limiting screw 10 can be installed on any threaded hole 9 on the center block 8. Adjust the distance between the two limiting screws 10 according to the width of the door panel, so that the distance between the limiting screws 10 is slightly larger than the width of the door panel. First rotate the left and right rotating plates 7 to horizontal, and then move the supporting plate 15 under the rotating plate 7 and the baffle 11, so that the supporting plate 15 supports the rotating plate 7 and The baffle 11 prevents it from rotating, and then the lower sandwich plate 12 is pulled out from the baffle 11, and the door panel is placed on the sandwich plate 12. The sandwich plate 12 supports the door panel, and the upper surface of the door panel is exposed to facilitate operation thereon. When the door panel needs to be flipped, the upper sandwich plate 12 is pulled out, the moving support plate 15 is staggered with the rotating plate 7, and the rotating plate 7 and the rotating shaft 6 are rotated half a circle to flip the door panel over. During the flipping process, the sandwich plate 12 and the limit screw 10 can prevent the door panel from falling out. The moving support plate 15 supports the baffle 11 again, and when the upper sandwich plate 12 is retracted, the upper surface of the door panel is exposed, and then the door panel is processed.
