DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Please refer to Figs. 1-3 In the embodiments of the utility model, a turnover device for concrete prefabricated component includes a base 1, a conveying roller 2 is rotatably installed at the top end of the base 1, a driving motor 3 is connected to one end of the conveying roller 2 through a rotating shaft and a shaft coupling, a transmission rod 4 is eccentrically rotatably connected to the outer wall of the other end of the conveying roller 2, and a turnover mechanism 5 is arranged on the base 1 and the conveying roller 2.

[0032] The turnover mechanism 5 includes a transmission unit and a turnover unit.

[0033] The transmission unit is used for providing power for the rotation of the turnover unit.

[0034] The turnover unit is used for turning over the material.

[0035] The turnover unit includes a support seat 501, a rotating rod 502, a turnover rod 503, a counterweight block 504 and an elastic support rod 509.

[0036] The support base 501 is fixed at the top end of the base 1, and is used to support the rotating rod 502;

[0037] The rotating rod 502 is rotatably installed on the inner wall of the support base 501 and penetrates through the support base 501 to the outside of the support base 501, and is used to synchronously drive the turnover rod 503 to rotate;

[0038] The turnover rod 503 is fixed on the outer wall of the rotating rod 502, and is used to drive the material located on the inner side of the turnover rod 503 to overturn;

[0039] The counterweight 504 is fixed at the top end of the end of the turnover rod 503, and is used to provide inertia for the rotation of the turnover rod 503;

[0040] The elastic support rod 509 is fixed on one side of the base 1 and below the turnover rod 503 on the turnover direction side, and is used to provide support for the turnover rod 503 after turnover;

[0041] The transmission unit includes a first spur gear 505, a second spur gear 506, a first bevel gear 507, and a second bevel gear 508;

[0042] The first spur gear 505 is fixed on the outer side of one of the conveying rollers 2, and is used to give the second spur gear 506 a rotating thrust;

[0043] The second spur gear 506 is connected to the outer wall of the base 1 through a "C" type support frame, and is used to synchronously drive the first bevel gear 507 to rotate;

[0044] The first bevel gear 507 is fixed on the outer wall of one side of the second spur gear 506, and is used to give the second bevel gear 508 a rotating thrust;

[0045] The second bevel gear 508 is fixed on one end of the rotating rod 502, and is used to synchronously drive the rotating rod 502 to rotate.

[0046] In this embodiment: by placing the material to be overturned on the upper surface of the conveying roller 2, the driving motor 3 is started, and the operation of the driving motor 3 drives one of the conveying rollers 2 connected to the output end to rotate, and the rotating conveying roller 2 synchronously drives one end of the transmission rod 4 to rotate circumferentially, thereby driving other conveying rollers 2 connected to the transmission rod 4 to rotate synchronously, thereby conveying the material located on the upper surface of the conveying roller 2;

[0047] Simultaneously, the rotating conveyor roller 2 will also synchronously drive the first spur gear 505 at its end to rotate clockwise. The clockwise rotation of the first spur gear 505 will synchronously provide a rotational thrust to the second spur gear 506. The second spur gear 506, under this force, will synchronously drive the first bevel gear 507, which is fixed on its outer wall, to rotate counterclockwise. When the material is conveyed to the inner side of the tilting rod 503, the outer wall teeth of the first bevel gear 507 will also contact the outer wall teeth of the second bevel gear 508, providing the second bevel gear 508 with a counterclockwise rotational thrust. The counterclockwise rotation of the second bevel gear 508 will synchronously drive the rotating rod 502 to rotate, causing the rotating rod 502 to drive the tilting rod 503 to rotate. This causes the material that has moved to the inner side of the tilting rod 503 to rotate under the thrust from the rotating tilting rod 503, until the outer wall teeth of the first bevel gear 507 no longer contact the second bevel gear 508. When the outer wall teeth of wheel 508 contact, the flipping rod 503 will also rotate 90 degrees. Under the action of the counterweight 504, the flipping rod 503 will continue to rotate counterclockwise, causing the material located inside the flipping rod 503 to fall onto the upper surface of the conveying roller 2. The falling material will complete the flipping operation and be subjected to the vibration force from the falling material, which will better facilitate demolding. The material falling onto the upper surface of the conveying roller 2 will continue to be conveyed by the rotation of the conveying roller 2, thus achieving the purpose of flipping and conveying the material. It should be noted that the elastic support rod 509 is in an inclined state, and the length of the transverse rod of the flipping rod 503 with the counterweight 504 is longer than that of the transverse rod without the counterweight 504, so that only the transverse rod with the counterweight 504 contacts the inclined surface of the elastic support rod 509 during the rotation of the flipping rod 503.

[0048] Please refer to this carefully. Figs. 1-3 There are two flipping rods 503. The two flipping rods 503 are circumferentially distributed on the outer wall of the rotating rod 502 with the axis of the rotating rod 502 as the center. The outer wall of the two flipping rods 503 is in the shape of an "I". The width at the connection point of the two flipping rods 503 is three times the diameter of the conveying roller 2. The outer wall teeth of the first bevel gear 507 are distributed at a 90-degree angle on the outer wall of the first bevel gear 507. The outer walls of the first spur gear 505 and the second spur gear 506 mesh. The outer wall of the transmission rod 4 is eccentrically connected to the outer walls of multiple conveying rollers 2 through the shaft. When the flipping rod 503 is in a lower position, the horizontal rod height is lower than the height of the conveying roller 2. It should be noted that the diameter of the first spur gear 505 is smaller than the diameter of the second spur gear 506, so that the first spur gear 505 rotates multiple times and drives the second spur gear 506 to rotate one revolution, ensuring that the material completely enters the groove of the flipping rod 503.

[0049] In the embodiment: through the structure, after the turnover rod 503 rotates 90 degrees, the second bevel gear 508 no longer receives the rotating thrust force from the first bevel gear 507, the turnover rod 503 rapidly rotates and falls under the action of gravity and the counterweight 504, the rotating and falling counterweight 504 contacts the inclined end of the elastic supporting rod 509, and the turnover rod 503 itself also receives the reaction force from the material to be positioned synchronously, so that the turnover rod 503 still keeps balance after falling back, and waits for the next material to enter the inside of the turnover rod 503 again, and so on, and the material is continuously and intermittently turned over.

[0050] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical scheme and the inventive concept of the present application, should be covered within the protection scope of the present application, if equivalent replacement or change is made within the technical range disclosed by the present application.
