Description

Technical Field

[0001] The utility model relates to the technical field of door preparation equipment, in particular to a pressurizing-baking equipment for a simple fireproof door structure. Background Art

[0002] Simple fire doors are usually made by filling the door panel shell with plate-shaped fireproof materials and then spraying fireproof glue on the gaps; then the entire filled and covered door structure is placed on a pressurized and baked equipment.

[0003] The conventional pressurizing-baking equipment on the market has the following structure: it has multiple layers of upper and lower pressing plates, each of which has a cavity filled with heated liquid; between adjacent pressing plates, the pressing plate at the bottom has a ring sleeve, and the pressing plate at the top has a pull rod, the lower end of the pull rod is inserted into the ring sleeve and leaks out, and the lower end of the pull rod is fixed with a limiter; the top pressing plate is connected to the telescopic cylinder. When working: when the upper pressing plate is lifted, the lower pressing plate is pulled upward by the pull rod and the ring, so that there is a gap between the pressing plates, the door structure is placed at the gap, and then the upper pressing plate falls back, the door structure is compressed, and the pressurization and heating are continued for a period of time (for example, 24h, 48h, etc.).

[0004] However, the problem caused by the structure of the existing pressurizing-baking equipment is that when the multi-layer pressing plate is pulled back to press the door structure, the pressure on the door structure at the bottom is greater than the pressure on the door structure at the top, which makes the quality of the produced door structure uncontrollable.

[0005] Therefore, our company has improved the common pressurizing-baking equipment and designed a new baking equipment in which each door structure is subjected to the same force, thus making it easier to control the quality of door production. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a pressurizing-baking equipment for a simple fireproof door structure, which can apply a clamping force of similar magnitude to door structures at different upper and lower positions to improve the quality between the door structures.

[0007] It should be noted that in conventional pressurizing-baking equipment, when the door structure needs to be placed, the topmost pressing plate is lifted by a telescopic cylinder, and the topmost pressing plate (first layer) lifts the next pressing plate (second layer) upward through a pull rod, and the second pressing plate lifts the third pressing plate upward through another pull rod, and so on, so that a gap is formed between two adjacent pressing plates, and then the door structure is placed;

[0008] When the door structure needs to be compressed, the telescopic cylinder gradually moves downward, and all the pressing plates move downward together. The pressing plate at the bottom first contacts the bottom plate of the frame and then remains motionless. Then the pressing plate at the upper layer contacts the door structure placed on the pressing plate at the bottom layer, and the door structures are compressed one by one from bottom to top.

[0009] But there is a problem: the pressure on the door structure is the sum of the pressure applied by all the pressure plates above it, all the door structures above it, and the telescopic cylinder. This results in the door structure being subjected to greater pressure the lower it is, and less pressure the higher it is. This makes the pressures on door structures at different heights inconsistent, making it impossible to control the clamping force well, and the quality of the fire door cannot be effectively controlled.

[0010] The utility model makes the pressures of door structures at different heights tend to be consistent through structural design, thereby facilitating the control of the quality of the fire door.

[0011] The purpose of the utility model is achieved through the following technical solutions: A pressurizing-baking equipment for a simple fire door structure, comprising a multi-layer pressing plate, the topmost pressing plate is connected to a telescopic cylinder, the telescopic cylinder is fixed on a frame, the pressing plate has an inner cavity and the inner cavity is filled with a heated high-temperature liquid;

[0012] The adjacent pressing plates are connected via a stretching mechanism;

[0013] A plurality of pressure relief mechanisms are provided between adjacent pressing plates, and the pressure relief mechanisms include a top piece and a spring, and the top piece and the spring are respectively and correspondingly installed on the pressing plate located at the top and the pressing plate located at the bottom; from bottom to top, the number of pressure relief mechanisms between adjacent pressing plates gradually decreases, forming a structure that makes the clamping force between adjacent pressing plates tend to be consistent;

[0014] That is, by controlling the pressure relief mechanisms between adjacent pressure plates at different heights, a portion of the pressure is offset by different numbers of pressure relief mechanisms, so that the final force of the door structure is made to be consistent.

[0015] As a preferred technical solution of the present application, the top piece is a micro hydraulic cylinder, and the output rod thereof has an annular disk; the corresponding output rod can be inserted into the spring and the annular disk is against the spring; the top piece on the same pressing plate is connected to the same output pump, and the top pieces on different pressing plates are connected to different output pumps. That is, the force of pressing the door structure is fine-tuned through the micro hydraulic cylinder.

[0016] As a preferred technical solution of the present application, the top piece is an electromagnetic telescopic rod with an annular disk on the rod; the corresponding rod can be inserted into the spring and the annular disk is against the spring. This is another design of the top piece, that is, the force of pressing the door structure is fine-tuned through the electromagnetic telescopic cylinder.

[0017] As a preferred technical solution of the present application, the pressure plate has ear plates on both sides, a plurality of springs are arranged on the upper surface of the ear plates, and a plurality of top pieces are arranged on the lower surface of the ear plates.

[0018] As a preferred technical solution of the present application, a plurality of columns are fixed on the upper surface of the ear plate, and a permanent magnet is also provided on the ear plate; the lower part of the spring is inserted into the column and fixed under the action of the permanent magnet, forming a structure that is easy to disassemble. That is, according to the actual situation, a certain number of springs can be put on or taken off, which is convenient for adjusting the clamping force.

[0019] As a preferred technical solution of the present application, the stretching mechanisms between different adjacent pressure plates are staggered, and the stretching mechanism includes a pull rod and a limit nut; there are light holes on both sides of the pressure plate, the upper end of the pull rod is fixed to the pressure plate, and the lower end passes through the light hole and is screwed with a limit nut.

[0020] The utility model has the following advantages:

[0021] (1) The pressure on each door structure at the height position can be adjusted, and the pressure on each door structure tends to be consistent, which can control the quality of the fire door structure;

[0022] Specifically, by increasing or decreasing the number of pressure relief mechanisms, that is, pressing once in advance and then lifting, the number of corresponding pressure relief mechanisms is initially reduced / increased according to the size of the pressure; then pressing again, and then fine-tuning through the top piece; thus, the pressure condition of the door structure can be accurately controlled;

[0023] (2) When reducing / increasing the number of pressurizing mechanisms, the spring can be directly removed / placed, and the adjustment is very simple and convenient; when fine-tuning the pressure, the extension and retraction amount of the top piece can be controlled (adjusted through the control panel and control buttons, which is a conventional design and will not be repeated here), and the adjustment is also very simple and convenient.

[0030] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0031] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0033] (Example 1)

[0034] like Figure 1 to Figure 3 As shown, a pressurizing-baking equipment for a simple fireproof door structure proposed in this embodiment includes a frame 3 and a multi-layer pressing plate 1. The frame 3 has a bottom plate and a top plate, and a multi-layer pressing plate 1 is arranged between the bottom plate and the top plate;

[0035] A telescopic cylinder 2 is fixed on the top plate of the frame 3, and the output end of the telescopic cylinder 2 is fixedly connected to the topmost / uppermost pressing plate 1, and the uppermost pressing plate 1 is connected to each pressing plate 1 of the lower layer through a stretching mechanism 4; a stretching mechanism is provided between adjacent pressing plates 1;

[0036] A plurality of pressure relief mechanisms 5 are provided between adjacent pressing plates 1, and the pressure relief mechanisms 5 include a top member 501 and a spring 502, and the top member 501 and the spring 502 are respectively and correspondingly installed on the pressing plate 1 located above and the pressing plate 1 located below; and the number of pressure relief mechanisms 5 between adjacent pressing plates 1 gradually decreases from bottom to top, forming a structure that makes the clamping force between adjacent pressing plates 1 tend to be consistent;

[0037] When the adjacent pressing plates 1 compress the door structure: the telescopic cylinder 2 extends downward, and all the pressing plates 1 move downward together. The pressing plate 1 of the bottom layer (the first to last pressing plate) first contacts the bottom plate - and does not remain stationary. Then the pressing plate 1 of the upper layer of the bottom layer (the second to last pressing plate) continues to move downward - until it contacts the door structure (the door structure is placed on the surface of the pressing plate 1 of the bottom layer); then the pressing plate 1 of the third to last layer compresses the door structure on the upper surface of the pressing plate 1 of the second to last layer, and gradually compresses each door structure from bottom to top; then the door structure is compressed. Force = the downward force of the telescopic cylinder 2 + the gravity of all the pressure plates 1 above the door structure + the gravity of all the door structures above the door structure - the force generated by the corresponding number of pressure reducing mechanisms 5. By adjusting the number of pressure-increasing mechanisms 5, the pressures on door structures at different heights can be made consistent, thereby ensuring that the pressures are consistent. This can control the specific pressure on the door structure (conventional equipment can only adjust the downward force of the telescopic cylinder 2, but cannot adjust the specific pressure on the door structure), and can also ensure that the quality of the compression of each door structure is consistent.

[0038] In this embodiment, a pressure sensor is provided on the lower surface of the pressing plate 1 .

[0039] In this embodiment, Figure 2 and Figure 3 As shown, ear plates 101 are fixed on both sides of each pressing plate 1, a plurality of columns 503 are fixed on the upper surface of the ear plates 101, and a top piece 501 is provided on the lower surface of the ear plates 101;

[0040] The lower part of the spring 502 is passed through the corresponding column 503; then a permanent magnet is placed on the ear plate 101, and the spring 502 is fixed by the permanent magnet. In the actual pressing process, according to the value fed back by the pressure sensor, it may be necessary to adjust the number of decompression mechanisms 5 between adjacent pressing plates 1 at the height position, and the corresponding spring 502 can be directly removed manually, and the spring 502 is fixed by the column 503 and the permanent magnet, which is convenient for the removal and placement of the spring 502.

[0041] In this embodiment, in order to more accurately control the pressing force, the top member 501 is further designed:

[0042] For example, the top piece 501 adopts a micro hydraulic cylinder, and has an annular disk 50101 on its output rod; the corresponding output rod can be inserted into the spring 502 and the annular disk 50101 is against the spring 502; the top piece 501 on the same pressing plate 1 is connected to the same output pump, and the top pieces 501 on different pressing plates 1 are connected to different output pumps; that is, the degree of downward extension of the top piece 501 is adjusted by the pump, thereby controlling the degree of compression of the annular disk 50101 on the spring 502;

[0043] Or, for example, the top piece 501 adopts an electromagnetic telescopic rod with an annular disk 50101 on the rod; the corresponding rod can be inserted into the spring 502 and the annular disk 50101 rests on the spring 502; that is, the amount by which the corresponding rod extends downward is adjusted by electromagnetic means, thereby controlling the degree of compression of the annular disk 50101 on the spring 502.

[0044] (Example 2)

[0045] On the basis of Example 1, the stretching mechanism 4 is also designed (it is a slight improvement of the conventional design, and of course the conventional design can also be directly adopted);

[0046] Specifically, Figure 3 As shown, the stretching mechanisms 4 between different adjacent pressing plates 1 are staggered; the stretching mechanism 4 includes a pull rod and a limit nut; ear seats are also provided on both sides of the pressing plate 1, and light holes are opened on the ear seats. The upper end of the pull rod passes through the corresponding hole of the upper pressing plate 1 and is screwed with a fixing nut, and the lower end of the pull rod passes through the light hole and is screwed with a limit nut;

[0047] Moreover, the corresponding light holes are staggered. For example, the light holes of the first-to-last laminate and the second-to-last laminate correspond to each other, the second-to-last laminate also has additional light holes corresponding to the light holes of the third-to-last laminate, and the light holes on the first-to-last laminate and the light holes on the third-to-last laminate do not correspond in position in the horizontal plane.

[0048] Alternatively, the stretching mechanism 4 is designed in a conventional manner.

[0049] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
