[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 - Figure 2 , the present utility model provides a technical solution:

[0024] Embodiment:

[0025] As Figure 1 and Figure 2 shown, a 90-degree flipping device for a fire door core material includes a bracket 1. A feeding area 2 and a discharging area 3 are provided on the bracket 1. A flipping assembly is provided between the feeding area 2 and the discharging area 3;

[0026] Multiple moving rollers 4 for translating the core material are provided in both the feeding area 2 and the discharging area 3;

[0027] The flipping assembly is used to drive the core material in the feeding area 2 to be flipped 90 degrees and then enter the discharging area 3.

[0028] The flipping assembly includes at least one set of flipping arms 5. The flipping arm 5 includes a wide arm 6 and a high arm 7. The wide arm 6 and the high arm 7 are vertically arranged. The wide arm 6 and the high arm 7 are rotatably connected to the bracket 1 through a rotating shaft 8. The flipping arm 5 is driven to flip by a driving member;

[0029] Before the core material is flipped, the wide arm 6 is located between the moving rollers 4 in the feeding area 2, and the upper surface of the wide arm 6 is below the bottom surface of the core material; after the core material is flipped, the high arm 7 is located between the moving rollers 4 in the discharging area 3, and the upper surface of the high arm 7 is below the bottom surface of the core material.

[0030] The wide arm 6 and the high arm 7 are connected by a horizontal arm 9. The rotating shaft 8 is coaxially arranged in the horizontal arm 9, and both ends of the rotating shaft 8 are located outside both ends of the horizontal wall. Both ends of the rotating shaft 8 are rotatably connected to the bracket 1 through bearing seats and bearings.

[0031] The driving member includes a telescopic cylinder 10 (wherein, the telescopic cylinder 10 is a pneumatic cylinder or a hydraulic cylinder). The end of the cylinder body of the telescopic cylinder 10 is hinged to the bracket 1 (through a connecting seat), and the end of the piston rod of the telescopic cylinder 10 is hinged to one end of the wide arm 6 away from the high arm 7.

[0032] Among them, 1. Three sets of flipping arms 5 are provided in this embodiment; 2. Before the core material enters the feeding area 2, the wide arm 6 is located between the moving rollers 4, and the wide arm 6 is in a horizontal state at this time; the high arm 7 is in a vertical state. 3. The moving rollers 4 are driven by a chain, a sprocket, and a motor. Adjacent two moving rollers 4 are connected by a chain and a sprocket. The specific driving principle is the prior art and will not be elaborated here. The moving rollers 4 in the feeding area 2 and the discharging area 3 are respectively driven by two motors.

[0033] Working principle: After the core material is demolded, it is sent to the feeding end of the feeding area 2 of the bracket 1 by a conveying device (which can be but is not limited to a conveyor belt). When the core material part (front end) enters the feeding area 2, the moving roller 4 in the feeding area 2 drives the core material to translate along the feeding area 2 until the core material completely enters the feeding area 2. When the core material is fed, ensure that the bottom surface and side surface of the core material are respectively in contact with the top surface of the wide arm 6 and the side surface of the high arm 7.

[0034] After the core material completely enters the feeding area 2, the piston rod of the telescopic cylinder 10 extends, driving the flipping arm 5 to flip. The flipping process is that the piston rod exerts an upward force on the end of the wide arm 6, and then drives the flipping arm 5 to rotate along the rotation axis 8 through the wide arm 6.

[0035] After the flipping ends, the high arm 7 is located between the moving rollers 4 in the discharging area 3, and the high arm 7 is in a horizontal state, and the wide arm 6 is in a vertical state. The flipped core material is sent out to the next cutting and separating station through the moving rollers 4 arranged in the discharging area 3, and then the core material cutting can start.

[0036] The utility model can realize the automatic 90-degree flipping of the core material by setting the flipping arm 5, and the core material is supported by the wide arm 6 and the high arm 7 during the flipping process, ensuring the stability of the core material flipping.

[0037] Furthermore, as Figure 2 shown, the bracket 1 is provided with a first sensor 11 and a second sensor 12. The first sensor 11 is arranged in the feeding area 2 for detecting the position of the wide arm 6; the second sensor 12 is arranged in the discharging area 3 for detecting the position of the high arm 7. Among them, the first sensor 11 and the second sensor 12 can be but are not limited to proximity switches.

[0038] When the wide arm 6 is horizontal, the set first sensor 11 can detect the position of the wide arm 6, indicating that the core material has not been flipped at this time; when the high arm 7 is horizontal, the set second sensor 12 can detect the position of the high arm 7, indicating that the core material flipping has ended at this time.

[0039] Furthermore, as Figure 1 and Figure 2 shown, positioning baffles 13 are respectively arranged on both sides of the bracket 1, and the positioning baffles 13 are perpendicular to the moving rollers 4.

[0040] Both ends of the positioning baffle 13 are turned outwards to form inclined guiding edges.

[0041] The arranged baffles and guiding edges are used for guiding and limiting when the moving rollers 4 drive the core material to translate, ensuring that the axis of the core material is perpendicular to the axis of the moving rollers 4 and preventing the core material from shifting.

[0042] The above are only the preferred embodiments of the present utility model. It should be understood that the present utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the techniques or knowledge in the relevant field. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
