Description

Technical Field

[0001] The utility model relates to the technical field of door leaf production equipment, in particular to a demoulding device for a fire door core material. Background Art

[0002] The production of fire door core materials includes the following processes: raw material feeding, raw material stirring, pouring and molding, demoulding, cutting off the bread top, cutting the integral core material into multiple single-board structures, and dust removal.

[0003] Among them, pouring and molding needs to be completed by placing raw materials into a pouring trolley. The pouring trolley includes a base and a template movably arranged on the base. The base is provided with rollers, and a movable box-shaped mold with an open top is formed between the template and the base. After the core material is molded, it is necessary to separate the core material from the mold.

[0004] At present, the separation of the core material and the mold requires manual intervention. For example, the template is manually removed, and after the core material is separated from the base, the template is reset. The disadvantages of this are as follows: First, manually taking the template cannot ensure uniform force application, so it may cause the template to collide with the core material, and finally affect the quality of the core material; second, the accuracy cannot be guaranteed when the template is reset. If the template is misaligned with the base, raw materials may leak from the misaligned gap between the two during pouring; finally, the labor intensity of workers is high. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a demoulding device for a fire door core material, which uses machinery to replace manual demoulding, and the demoulding process does not require manual participation; the magnitude of the demoulding force is uniform and controllable, which can avoid the collision between the template and the core material during the demoulding process, and at the same time can avoid the template driving the core material to tilt, misalign or shake up and down.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Refer to Figures 1 - 8 , the present utility model provides a technical solution:

[0036] Embodiment:

[0037] As shown in Figures 1 - 8 the figure, a demoulding device for a fireproof door core material includes a frame 1, a track 2 passing through the frame 1, and a demoulding assembly;

[0038] The track 2 is used to carry and transfer the pouring trolley 3;

[0039] The demoulding assembly includes a material plate separating manipulator and a material pushing manipulator. The material plate separating manipulator is arranged on the frame 1 and is used to separate the template 4 of the pouring trolley 3 from the core material 21 and the base 5 of the pouring trolley 3 at the same time;

[0040] The material pushing manipulator is arranged on one side of the track 2 and is used to horizontally push the core material 21 to separate the core material 21 from the base 5.

[0041] As shown in Figure 2 , Figure 3 and Figure 6 the figure, the material plate separating manipulator includes a lifting mechanism 6 and a material pressing mechanism. The lifting mechanism 6 is connected to the frame 1 and is used to linearly lift the template 4 upward until the bottom of the template 4 is higher than the top of the core material 21; the material pressing mechanism is connected to the lifting mechanism 6 and is used to press the core material 21 during the lifting process of the template 4 (to keep the relative static state of the core material 21 and the base 5).

[0042] As shown in Figure 2 and Figure 3 the figure, the lifting mechanism 6 includes a horizontally arranged lifting frame 7 and at least one group (two groups are symmetrically arranged in this embodiment) of claw hooks 8 arranged on both sides of the lifting frame 7. The lifting frame 7 is connected to the frame 1 through a first telescopic member 9 (with a vertical axis) (a guide rod is arranged between the lifting frame 7 and the frame 1);

[0043] As shown in Figures 1 - 3 the figure, the two sides of the pouring trolley 3 extend outward to form a pulling part 18 (a part of the pouring trolley 3 is horizontal to avoid interference with the claw hooks 8);

[0044] The claw hooks 8 are located on both sides of the pouring trolley 3, and the claw hooks 8 are located below the pulling part 18 (as shown in Figure 7 the figure, a gap is provided between the side wall of the pouring trolley 3 and the side of the claw hook 8 close to the pouring trolley 3, so as to avoid friction between the two when the pouring trolley 3 enters the demoulding device / frame 1).

[0045] As shown in Figure 2 the figure, the material pressing mechanism includes a material pressing frame 10 and a second telescopic member 11. The material pressing frame 10 is movably connected to the lifting frame 7 through the second telescopic member 11, and the material pressing frame 10 is located below the lifting frame 7.

[0046] As shown in Figure 2As shown, the pusher manipulator includes a base 15 and a third telescopic member 16 horizontally arranged on the base 15. The movable end of the third telescopic member 16 is connected to a vertical push plate 19.

[0047] The first telescopic member 9, the second telescopic member 11, and the third telescopic member 16 are cylinders or hydraulic cylinders.

[0048] Among them, as Figure 7 and Figure 8 shown, on the other side of the track 2 relative to the pusher manipulator, there is a centering wheel 20 with a vertical axis. The centering wheel 20 is used to limit the base 5 when the pusher manipulator pushes the core material 21, so as to avoid the base 5 being driven by the friction force between the core material 21 and the base 5 when the core material 21 moves. At the same time, after the pushing is completed, the rolling friction between the base 5 and the centering wheel 20 can reduce the friction loss between the base 5 and the centering wheel 20. 2. On the other side of the track 2 relative to the pusher manipulator, there is a material receiving mechanism for receiving the pushed core material 21. 3. One end of the base 5 is provided with a positioning plate for positioning the template 4.

[0049] Working principle: The pouring trolley 3 enters the frame 1 from one end of the track 2. In this process, the pouring trolley 3 enters the frame 1 (demolding station).

[0050] At this time, first, the second telescopic member 11 drives the pressure material frame 10 to descend until the pressure material frame 10 contacts and holds the top of the core material 21. Then, the first telescopic member 9 drives the lifting frame 7 to ascend. When the lifting frame 7 ascends, the hook 8 drives the template 4 to ascend synchronously until the bottom surface of the template 4 is higher than the top surface of the core material 21 (i.e., the template 4 is separated from the core material 21). During this process, since the core material 21 is pressed by the pressure material frame 10, the template 4 can be prevented from driving the core material 21 up and down, resulting in tilting, misalignment, or jitter.

[0051] When the template 4 is separated from the core material 21, the pusher manipulator acts: The third telescopic member 16 drives the push plate 19 to push the core material 21 to move horizontally, thereby separating the core material 21 from the base 5. After the core material 21 is separated from the base 5, the pressure material frame 10 descends and resets, and the template 4 falls back onto the base 5. Then, the pouring trolley 3 moves forward as a whole, and the demolding of the core material 21 is completed.

[0052] When the next pouring trolley 3 carrying the core material 21 enters the frame 1, repeating the foregoing actions can achieve cyclic demolding.

[0053] The utility model replaces manual demolding with machinery, and the demolding process does not require manual participation; the demolding force is evenly controllable, which can avoid collisions between the template 4 and the core material 21 during the demolding process, and at the same time can prevent the template 4 from driving the core material 21 up and down, resulting in tilting, misalignment, or jitter.

[0054] Furthermore, as Figure 4 andFigure 5 As shown, there is a gap between the pressure plate 10 and the top of the core material 21. Along the length direction of the track 2 on the pressure plate 10, a plurality of (three in this embodiment) detection components for detecting the core material 21 are provided.

[0055] An installation through slot is provided on the pressure plate 10;

[0056] The detection component includes a vertically arranged detection plate 12. The first end of the detection plate 12 (which can be, but is not limited to, a rotating shaft or a pin) is rotatably connected to the groove wall of the installation through slot. The second end of the detection plate 12 is freely arranged. An arc-shaped groove 13 is provided in the middle of the detection plate 12. The middle of the detection plate 12 is slidably connected to the groove wall of the installation through slot through the arc-shaped groove 13 and a pin;

[0057] The bottom surface of the second end of the detection plate 12 is located below the bottom surface of the pressure plate 10; a first sensor 14 corresponding to the second end of the detection plate 12 is provided on the pressure plate 10. Among them, the first sensor 14 can be, but is not limited to, a proximity switch or a travel switch.

[0058] When the core material 21 enters the frame 1, first, the second telescopic member 11 acts to drive the pressure plate 10 to move downward. When the pressure plate 10 moves downward, the detection plate 12 below it first contacts the top surface of the core material 21.

[0059] As the pressure plate 10 continues to move downward, the second end of the detection plate 12 is lifted by the core material 21. When the second end of the detection plate 12 contacts or approaches the first sensor 14, the first sensor 14 detects a signal, indicating that there is core material 21 at this position. When core material 21 is detected at all three positions, it means that the core material 21 is in place.

[0060] After that, the first telescopic member 9 can be started to separate the template 4 from the core material 21.

[0061] The provided detection component realizes the detection of the position of the core material 21 while applying pressure to the core material 21.

[0062] Furthermore, as Figure 6 shown, a second sensor 17 for detecting the upward position of the lifting frame 7 is provided on the frame 1. Among them, the second sensor 17 can be, but is not limited to, a proximity switch or a travel switch. The provided second sensor 17 is used to detect whether the position of the lifting frame 7 is lifted in place (the first telescopic member 9 stops when it is in place), so as to avoid the lifting frame 7 from being lifted excessively and doing useless work.

[0063] 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, 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.
