Specific embodiments

[0029] Next, the technical solutions of the present invention 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 invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0030] Refer to Figures 1 - 6 , the present invention provides a technical solution:

[0031] Embodiment:

[0032] As Figures 1 - 6 shown, a device for quickly cutting the bread top of a fire door core material includes a conveying device 1 and a square frame 2. The conveying device 1 passes through the square frame 2, and a cutting tool 3 and a material removing component 4 are sequentially arranged on the square frame 2 along the feeding direction of the conveying device 1;

[0033] The cutting tool 3 is used for cutting the bread top 6 of the fire door core material 5;

[0034] The material removing component 4 is used for separating the cut bread top 6 from the fire door core material 5.

[0035] The conveying device 1 includes a conveyor belt, and the feeding end of the conveyor belt is located outside the square frame 2.

[0036] On both sides of the conveyor belt, there are vertical positioning stoppers 7 respectively, and the positioning stopper on one side of the feeding end of the conveyor belt is movably arranged (along the width direction of the conveyor belt). On one side of the feeding end of the conveyor belt, there are (2 - 4) hydraulic cylinders or air cylinders, and the piston rod of the hydraulic cylinder or air cylinder is connected to the positioning stopper 7. When the piston rod moves, it drives the positioning stopper to approach the positioning stopper 7 on the other side, reducing the distance between the two positioning stoppers 7, and thus clamping the whole piece of fire door core material 5.

[0037] As Figures 1 - 3 shown, the tool 3 includes a driving wheel 8, a driven wheel, and a circular saw blade 9 arranged on the driving wheel 8 and the driven wheel.

[0038] On the square frame 2, there is a vertical first slide rail 10. The tool 3 is arranged on the bracket 25, and the bracket 25 is slidably connected to the first slide rail 10 through a first slider 11;

[0039] The bracket 25 is driven by a vertical driving member 12. The driving member is an electric telescopic rod, an air cylinder or a hydraulic cylinder. Taking the air cylinder as an example, the piston rod of the air cylinder is connected to the bracket 25, and the cylinder body of the air cylinder is arranged on the square frame 2.

[0040] The tool 3 is connected to the square frame 2 through the bracket 25, the first slide rail 10, and the first slider 11. Driven by the driving member, it drives the bracket 25 to move in the vertical direction, and thus adjusts the height of the tool 3 to adapt to the cutting of the bread top 6 of the fire door core material 5 with different heights.

[0041] The material removing assembly 4 includes a push plate 13 and a transverse driving member 14 for driving the push plate 13 to move along the width direction of the conveyor belt;

[0042] The push plate 13 is arranged corresponding to the side wall of the cut bread top 6.

[0043] As Figures 4 - 6 shown, the transverse driving member 14 includes a driving chain 15, a second slide rail 16 arranged along the width direction of the conveyor belt, and a connecting plate 17. The driving chain 15 is arranged in parallel with the second slide rail 16. The second slide rail 16 and the driving chain 15 are respectively connected to the square frame 2. The connecting plate 17 is slidably connected to the second slide rail 16 through a second slider 18, and the connecting plate 17 is also connected to the driving chain 15 through a connecting block 19.

[0044] At the bottom of the connecting plate 17, there is a rotating shaft 21 rotatably connected through an ear plate 20. On the rotating shaft 21, there are a plurality of L-shaped rib plates 22. One end of the rib plate 22 is connected to the push plate 13, and the other end of the rib plate 22 is provided with a driving shaft 23;

[0045] A telescopic cylinder 26 is provided on the connecting plate 17, and the piston rod of the telescopic cylinder 26 is connected to the drive shaft 23 (where the telescopic cylinder 26 is a hydraulic rod or a pneumatic cylinder). Among them, the push plate 13 is connected to the connecting plate 17 through the rib plate 22, the rotating shaft 21, the telescopic cylinder 26, and the drive shaft 23. When the telescopic cylinder 26 acts, the angle of the push plate 13 can be adjusted through the rib plate 22, the rotating shaft 21, and the drive shaft 23, so as to adapt to the separation of the bread tops 6 of different heights.

[0046] An inclined guide plate 24 is provided on the side of the square frame, and the guide plate 24 is located outside the conveyor belt (where the lowest point of the bread top 6 is higher than the highest point of the guide plate 24).

[0047] Among them, 1. The lowermost side of the circular saw blade 9 corresponds to the lowermost side of the bread top 6 to ensure that the bread top 6 can be completely cut off. 2. The drive motor is driven by a motor.

[0048] Working principle: The fireproof door core material 5 with the bread top 6 to be cut enters the square frame 2 from the feeding end of the conveyor belt, and the circular saw blade 9 is started before the fireproof door core material 5 with the bread top 6 to be cut enters. When the fireproof door core material 5 with the bread top 6 to be cut is placed at the feeding end of the conveyor belt, one side (2 - 4) of the feeding end of the conveyor belt is provided with hydraulic cylinders or pneumatic cylinders, and the piston rods of the hydraulic cylinders or pneumatic cylinders are connected to the positioning stoppers 7. When the piston rods act, they drive the positioning stoppers to approach the positioning stoppers 7 on the other side, reducing the distance between the two positioning stoppers 7, thereby clamping the whole fireproof door core material 5.

[0049] As the fireproof door core material 5 with the bread top 6 to be cut enters the square frame 2 under the action of the conveyor belt, the circular saw blade 9 cuts off the bread top 6 of the fireproof door core material 5 with the bread top 6 to be cut.

[0050] The cut bread top 6 remains on the fireproof door core material 5. As the conveyor belt continues to run, the bread top 6 and the fireproof door core material 5 run to the material removal assembly 4, and then the material removal assembly 4 separates the bread top 6 from the fireproof door core material 5. The separation process is as follows: The drive chain 15 runs, driving the connecting plate 17 and the push plate 13 connected to the connecting plate 17 to run along the width direction of the conveyor belt through the connecting block 19. When the push plate 13 moves, it first contacts the side wall of the cut bread top 6; as the drive wheel 8 continues to run, the bread top 6 is pushed to be separated from the fireproof door core material 5. The separated bread top 6 drops and is guided by the guide plate 24 to move to the waste collection box. When the bread top 6 is separated from the fireproof door core material 5, the drive chain 15 runs in the reverse direction to reset, preparing for the next separation of the bread top 6 and the fireproof door core material 5.

[0051] The utility model is provided with a tool cooperating with a conveying device to realize the cutting of the bread top of the fire door core material, and the automatic separation of the cut bread top and the fire door core material is realized by arranging a material removing component; the utility model realizes the automatic cutting and removal of the bread top by mechanical equipment instead of manual labor, greatly improving the cutting efficiency of the bread top and the product quality.

[0052] The above are only the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, 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 technology or knowledge in related fields. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the utility model should all be within the protection scope of the appended claims of the utility model.
