Description

Technical Field

[0001] This invention relates to the field of mortar board production technology, and more specifically, to an integrated device for automated steam curing and demolding of cement mortar boards. Background Technology

[0002] Cement mortar board is a building material made primarily of cement and sand. It possesses excellent properties such as fire resistance, moisture resistance, sound insulation, and durability, and is widely used in interior and exterior wall panels, floor slabs, and other construction applications. In the production process of cement mortar board, after the mortar is poured into the molding mold, it must undergo high-temperature and high-humidity steam curing (referred to as "steam curing") to accelerate the hydration reaction of the cement and quickly reach the design strength. After steam curing, the cured mortar board needs to be removed from the mold (i.e., "demolding").

[0003] The existing production process for cement mortar boards typically involves sending a trolley full of molds into a large steam curing chamber for curing. After curing, the trolley is pushed out, and the molds are manually removed one by one. The mortar boards are then detached by manually turning the molds over and tapping their bottoms.

[0004] This traditional method has very obvious technical flaws:

[0005] First, the demolding process is extremely labor-intensive and inefficient. Because the mortar slabs have considerable weight and adhere to the mold, manually flipping and tapping them one by one for demolding is extremely physically demanding and time-consuming. In mass production, the demolding process often becomes a bottleneck limiting the overall production speed.

[0006] Secondly, the quality of demolding is unstable, which can easily cause product damage. It is difficult to maintain a consistent force when manually turning and tapping, and uneven force can easily cause the edges of the mortar board to chip, break, or develop hidden cracks, increasing the scrap rate of the product.

[0007] Third, the steam curing and demolding processes are separate. Curing molds in large steam curing chambers is not only energy-intensive (requiring heating the entire large space), but also involves cumbersome processes for moving molds in and out of the warehouse.

[0008] Therefore, the industry urgently needs a specialized device that can miniaturize and seal the steam curing space, and achieve automated batch flipping and assisted demolding after steam curing. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention provides an integrated automated demolding device for steam-cured cement mortar boards. It aims to solve the technical problems in existing mortar board production where manual demolding of each board after steam curing is required, which results in high labor intensity, time and effort consumption, easy breakage, and serious impact on production efficiency.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] An automated demolding device for steam curing cement mortar boards includes a support frame with flipping seats on both sides. A storage component is rotatably installed inside the flipping seat, and a placement component is installed inside the storage component. An extension frame is fixedly installed on one side of the support frame, and a drive motor for driving the storage component and placement component to flip is fixedly installed on the upper end of the extension frame. The storage component has a cavity for sealing steam. A steam generator is provided on the other side of the support frame, and the steam generator is connected to the internal cavity of the storage component for introducing steam into the cavity for steam curing. The placement component is used to place the molding mold containing mortar material in layers.

[0012] Preferably, the storage component includes a storage box, with a flip shaft fixedly installed at each end of the storage box, and the flip shaft is rotatably connected to an adjacent flip seat.

[0013] Preferably, a distribution pipe is fixedly installed inside the storage box. The distribution pipe has several nozzles distributed vertically. One end of the distribution pipe is hollow inside the flip shaft, and the other end of the distribution pipe is connected to the hollow channel inside the flip shaft.

[0014] Preferably, the steam generator is provided with a discharge pipe for discharging steam on one side, and a rotary joint is installed at the other end of the rotating shaft. A conveying pipe is rotatably installed at one end of the rotary joint, and the conveying pipe is fixedly connected to the discharge pipe.

[0015] Preferably, a driven gear is fixedly installed on the outer side of the other end of the flipping shaft, and a transmission gear is fixedly installed on the output end of the drive motor, the transmission gear meshing with the driven gear.

[0016] Preferably, limit slide rails are fixedly installed on both sides of the surface of the storage box, a matching screw hole sleeve is fixedly installed in the middle of the surface of the storage box, and several insert plates are fixedly installed in the internal cavity of the storage box.

[0017] Preferably, the placement assembly includes a sealing cover plate, which is snapped to the opening of the storage box. The surface of the sealing cover plate is provided with several fixed supports, and several layers of placement mesh plates are fixedly installed inside the fixed supports. The molding mold and mortar material are placed on the surface of the placement mesh plate, and each layer of the placement mesh plate is interlocked and limited with the adjacent interlocking card plate.

[0018] Preferably, a matching sliding plate is fixedly installed on both sides of the sealing cover, and the matching sliding plate is slidably connected to the adjacent limiting slide rail;

[0019] A boss is provided on one side of the middle part of the sealing cover plate. A servo motor is fixedly installed inside the boss. A drive screw is fixedly installed at the output end of the servo motor. The body of the drive screw is threadedly engaged with the screw hole of the matching screw hole sleeve.

[0020] Preferably, the sealing cover has an exhaust port at its center, and a pressure relief valve is fixedly installed inside the exhaust port to discharge excess steam.

[0021] Preferably, a set of vibration motors are fixedly installed on the upper surface of the sealing cover plate, and the vibration motors are used to generate high-frequency vibrations for placing the mesh plate and forming mold.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This invention breaks the traditional separation mode of "large steam room curing + manual demolding one by one". The equipment has a sealed storage box forming a miniature high-efficiency steam curing chamber. Once the steam curing is completed, the drive motor directly drives the entire storage box and all the molds inside to rotate 180 degrees. Due to gravity, the mortar board will automatically slide out from the inverted molding mold and fall directly onto the placement mesh plate. The operator only needs to remove the empty mold located above to obtain the mortar board below, completely eliminating the heavy labor of manually flipping the heavy molds one by one, and greatly improving the demolding efficiency and the level of production automation.

[0024] (2) A vibration motor is integrated into the sealing cover. After the box is rotated 180 degrees, the vibration motor is started. The high-frequency vibration wave is transmitted to each layer of mesh plate and forming mold through the fixed support. It can quickly destroy the surface tension and adhesion between the mortar board and the inner wall of the mold, so that the board can slide down smoothly and without damage. It effectively avoids the problem of board chipping or breaking caused by manual knocking, and significantly improves the yield.

[0025] (3) The servo motor and drive screw are integrated into the sealing cover plate. With the help of the slide rail, the placement component filled with molds can be automatically pushed into or pulled out of the storage box. This allows the loading (placing uncured molds) and unloading (removing finished products and empty molds) processes to be carried out in a completely open space outside the box, with a large operating space and high safety.

[0026] (4) The interlocking card plate set on the inner wall of the storage box forms a precise interlocking fit with the placement mesh plate, so that during the 180-degree large flip, each layer of placement mesh plate is firmly locked in the vertical direction, and there will be no interlayer compression or mold overturning misalignment, ensuring the smooth operation of the equipment and the safety of the plate.

[0027] (5) Steam is introduced through the hollow rotating shaft and evenly sprayed into the entire sealed chamber through densely arranged nozzles on the distribution pipe. The steam is evenly distributed, the heat transfer is fast and the heat loss is minimal, ensuring that each layer of mortar board is heated and moistened in a consistent manner, which significantly improves the curing quality and final strength of the mortar board.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1 to 3 As shown, an automated demolding integrated device for steam curing cement mortar boards includes a support frame 1, with a flipping seat 2 on each side of the support frame 1. A storage component 5 is rotatably installed inside the flipping seat 2, and a placement component 6 is installed inside the storage component 5. An extension frame 3 is fixedly installed on one side of the support frame 1, and a drive motor 4 for driving the flipping of the storage component 5 and the placement component 6 is fixedly installed on the upper end of the extension frame 3. A steam generator 7 is provided on the other side of the support frame 1. The steam generator 7 is connected to the storage component 5. The storage component 5 is used to limit the steam range, and the placement component 6 is used to store the molding mold 10 and mortar material.

[0041] like Figures 3 to 7 , Figure 10 As shown, the storage assembly 5 includes a storage box 501, with a flip shaft 502 fixedly installed at both ends of the storage box 501. The flip shaft 502 is rotatably connected to the adjacent flip seat 2. The storage box 501 can be flipped, thereby causing the multi-layer placement mesh plate 607 inside to also flip, so that the placed molding mold 10 can be flipped, and its internal material is automatically placed on the surface of the placement mesh plate 607.

[0042] In this application, a distribution pipe 507 is fixedly installed inside the storage box 501. The distribution pipe 507 has several nozzles 5071 distributed vertically. One end of the distribution pipe 507 is hollow inside the rotating shaft 502. One end of the distribution pipe 507 is connected to the inside of the rotating shaft 502.

[0043] The steam generator 7 has a discharge pipe 8 for discharging steam on one side, and a rotary joint 506 is installed at the other end of the rotating shaft 502. A conveying pipe 9 is rotatably installed at one end of the rotary joint 506, and the conveying pipe 9 is fixedly connected to the discharge pipe 8.

[0044] To replenish the storage tank 501 with steam for steam curing the mortar boards on the mesh plate 607, steam is generated by starting the steam generator 7. The steam is continuously delivered to the conveying pipe 9 through the discharge pipe 8. The rotating joint 506 allows the steam to be delivered to the distribution pipe 507, which distributes the steam around the outside of the mesh plate 607. With the help of several nozzles 5071, the steam can steam cure the mortar boards inside the storage tank 501. The above structure allows the present application to steam cure mortar boards in batches, thereby efficiently improving the quality of the mortar boards.

[0045] In the specific setup, a driven gear 503 is fixedly installed on the outer side of the other end of the flip shaft 502, and a transmission gear 401 is fixedly installed on the output end of the drive motor 4. The transmission gear 401 meshes with the driven gear 503.

[0046] To facilitate quick removal of the molding mold 10 and achieve automatic demolding, the drive motor 4 is started to drive the transmission gear 401 to rotate. During the rotation of the transmission gear 401, the meshing transmission between the transmission gear 401 and the driven gear 503 drives the driven gear 503 to rotate as well. The rotational connection between the flipping shaft 502 and the flipping seat 2 causes the entire storage box 501 to be flipped, thereby enabling multiple molding molds 10 inside the placement component 6 to be flipped synchronously. This allows the molded mortar board to be placed on the placement mesh plate 607, so that the operator can directly remove the molding mold 10 from the top without having to manually flip and remove each molded mortar board one by one, effectively reducing the workload.

[0047] It should be noted that during the driving process of the drive motor 4, the storage box 501 rotates by 180° in a single rotation, and then rotates in the opposite direction by 180° in the next rotation to avoid affecting the winding of other motors.

[0048] It should be noted that limit slide rails 504 are fixedly installed on both sides of the surface of the storage box 501, a matching screw hole sleeve 505 is fixedly installed in the middle of the surface of the storage box 501, and several insertable card plates 508 are fixedly installed in the internal cavity of the storage box 501.

[0049] To prevent the mold 10 from deviating in position when the storage box 501 is flipped, which could cause the mortar board to fall off, several interlocking clamps 508 are provided inside the storage box 501. The interlocking clamps 508 are arranged according to the placement position of the mold 10, so that they can interlock and combine with the placement mesh 607, thereby limiting the position of the mold 10 inside each layer of placement mesh 607, effectively improving the stability of the mold 10 inside the storage box 501.

[0050] like Figure 3 , Figure 6 , Figure 8 , Figure 10 As shown, the placement component 6 includes a sealing cover plate 601, which is snapped to the opening of the storage box 501. Several fixed supports 606 are provided on the surface of the sealing cover plate 601, and several layers of placement mesh plates 607 are fixedly installed inside the fixed supports 606. The molding mold 10 and mortar material are placed on the surface of the placement mesh plate 607, and each layer of placement mesh plate 607 is interlocked and limited with the adjacent interlocking card plate 508.

[0051] In order to accommodate multiple molding dies 10, several layers of placement mesh plates 607 are installed inside the fixed support column 606, wherein a row of molding dies 10 is placed between every two layers of placement mesh plates 607, wherein when the storage box 501 is flipped, the molding die 10 can be transferred from the surface of one layer of placement mesh plate 607 to the surface of another layer of placement mesh plate 607.

[0052] In this embodiment, a mating slide plate 602 is fixedly installed on both sides of the sealing cover plate 601, and the mating slide plate 602 is slidably connected to the adjacent limiting slide rail 504;

[0053] A boss 603 is provided on one side of the middle part of the sealing cover plate 601. A servo motor 604 is fixedly installed inside the boss 603. A drive screw 605 is fixedly installed at the output end of the servo motor 604. The body of the drive screw 605 is threadedly engaged with the screw hole of the matching screw sleeve 505.

[0054] To open the sealing cover 601, the servo motor 604 is started to drive the drive screw 605 to rotate. During the rotation of the drive screw 605, the sliding contact plate 602 is connected to the adjacent limit slide rail 504 to limit the movement position of the sealing cover 601. When the drive screw 605 rotates, its rod body engages with the threaded hole of the screw sleeve 505, thereby adjusting the distance between the sealing cover 601 and the storage box 501. This causes the placement mesh plate 607 and its internal placement mesh plate 607 to move accordingly, thus realizing the automatic opening or closing of the sealing cover 601 for easy use.

[0055] In the specific configuration, the sealing cover 601 has a vent 6011 at its center, and a pressure relief valve 6012 is fixedly installed inside the vent 6011. The pressure relief valve 6012 is used to discharge excess steam. To prevent excessive pressure inside the storage tank 501 caused by continuous steam entering, the vent 6011, in conjunction with the pressure relief valve 6012, can discharge excess steam to the outside, thereby ensuring the stability of the storage tank 501.

[0056] Among them, a set of vibration motors 11 are fixedly installed on the upper surface of the sealing cover plate 601. The vibration motors 11 are used to make the mesh plate 607 and the forming mold 10 vibrate at high frequency.

[0057] To further assist in the demolding of the flipping molding mold 10, a set of vibration motors 11 is provided on the sealing cover plate 601. By starting the vibration motors 11, vibration is generated, which is transmitted to each layer of the placement mesh plate 607 through the fixed support column 606. With the limiting setting of the interlocking card plate 508, the molding mold 10 on each layer of placement mesh plate 607 vibrates accordingly. The molding mold 10 moves with the mortar board inside it, so that the mortar board can be separated from the molding mold 10 during subsequent flipping, which makes it easy for personnel to quickly remove the mortar board and molding mold 10 after automatic demolding.

[0058] The heating system of the steam generator 7 is a technical means that is already mastered and well known to those skilled in the art, and the steam generation of the steam generator 7 is not the object of improvement in this application. Those skilled in the art can choose to use existing steam generating equipment in conjunction with it.

[0059] The working principles and wiring methods of the steam generator 7, vibration motor 11, servo motor 604, and drive motor 4 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0060] The working principle of this integrated automatic demolding device for steam curing cement mortar boards:

[0061] 1. Automatic loading and unloading: In the initial state, the servo motor 604 is started, driving the lead screw 605 to rotate, smoothly pushing the placement component 6 outward from inside the storage box 501. The operator places the molding mold 10, filled with cement mortar, onto the open placement mesh plates 607 of each layer in sequence.

[0062] 2. Sealing upon entry into storage: After loading is completed, the servo motor 604 reverses, automatically pulling the placement component 6 back into the storage box 501. At this time, the placement mesh plate 607 is locked between the interlocking card plate 508, and the sealing cover plate 601 is tightly fastened and sealed with the box opening.

[0063] III. High-Temperature Steam Curing: The steam generator 7 is started, and high-temperature steam enters the distribution pipe 507 via the rotary joint 506 and the hollow rotating shaft 502. The steam is then evenly sprayed into the sealed storage tank 501 by the nozzles 5071 on each layer. Under constant temperature and humidity and high pressure, the mortar board rapidly hydrates and solidifies. The pressure relief valve 6012 automatically regulates the internal pressure.

[0064] IV. Overall Rotation: After the steam curing reaches the specified time, the steam supply is stopped. The drive motor 4 is started, and the rotating shaft 502 is driven through gear transmission, causing the entire storage box 501, along with all the internal molds, to rotate 180 degrees and lock. At this time, the molding mold 10, which was originally open upwards, becomes open downwards (inverted state), and its bottom surface is supported by another layer of mesh plate that was originally located above it.

[0065] 5. Vibration Demolding: Start the vibration motor 11 on the sealing cover plate 601. Under the action of vibration, the mortar plate overcomes the adhesion force with the side wall of the molding mold 10 and automatically slides out of the mold due to gravity, landing smoothly on the placement mesh plate 607 below (in the above process, the mold is on top of the mortar plate).

[0066] VI. Unloading and Material Discharge: Drive motor 4 reverses 180 degrees to reset the housing (it can also be unloaded while inverted, depending on the production line settings). Servo motor 604 is activated to fully extend the demolding placement component 6. At this point, the operator is faced with layers of completely separated molds and mortar slabs. The operator only needs to use one hand or a suction cup mechanism to first remove the lighter, empty mold from the top, and then directly move the well-formed mortar slab from below. The entire demolding process requires no manual turning or tapping, greatly reducing labor intensity and achieving a high degree of automation in the steam curing demolding process.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
