Description

Technical Field

[0001] This invention relates to the field of concrete building materials technology, and more specifically, to a curing device for manufacturing energy-saving cement cover plates. Background Technology

[0002] In the production process of reinforced concrete cable covers, early curing after cement pouring is a crucial step in determining the final strength and appearance quality of the product. To prevent excessive moisture loss leading to shrinkage and cracking, existing technologies widely employ film-covering curing processes to replace traditional water-spraying curing. Typical existing film-covering curing devices usually include a roller conveyor with a steel cover mold holding the freshly poured cement slurry. A film-covering machine is positioned above a specific station on the conveyor line. The process involves the film-covering machine outputting a layer of plastic film, which is then laid flat on the top surface of the mold. The film is then cut by a cutter, and finally, a flattening mechanism adheres the film to the exposed cement surface. For example, Chinese Patent CN207044383U discloses a film-covering device and production equipment for reinforced fiber cement extruded wall panels.

[0003] The aforementioned prior art reduces moisture evaporation from the cement surface by covering the concrete product with a film. While this reduces moisture evaporation to some extent, it still has the following drawbacks in the actual production of reinforced concrete cable covers: The design blind spot of the prior art is that it only focuses on the top surface of the cement and completely ignores the sides of the mold. In actual production, after the cement slurry is poured into the mold, due to the settlement and shrinkage of the cement itself and the microscopic unevenness of the mold's inner wall, tiny physical gaps inevitably form between the edge of the cement cover and the side wall of the steel mold. When the cement surface is covered with a film, moisture evaporation is blocked, but the gaps in the side walls are directly connected to the outside air. Due to the extremely small gaps, a strong capillary effect occurs here. Under the action of capillary force, moisture at the edge of the cover is rapidly and continuously drawn into the outside air through these gaps. This can cause the water loss rate at the edge of the cover plate to be much higher than that in the center area, and the water-cement ratio at the edge to drop sharply. Due to the extreme unevenness of humidity inside and outside, the edge of the cover plate will generate huge shrinkage stress, which in turn leads to the most fatal quality defect of the cable cover plate, namely edge shrinkage cracks. These tiny cracks are very easy to expand when subjected to loads, thus directly causing the cover plate to be scrapped. Summary of the Invention

[0004] This invention provides an energy-saving curing device for manufacturing cement cover plates. It solves the problem mentioned in the background art by physically blocking the communication between the side wall gaps and the outside air by covering the four sides of the outer wall of the cover plate mold containing cement with a film. That is, the prior art only covers the top surface of cement, which causes capillary siphon phenomenon in the cement side wall gaps, resulting in excessively rapid local water loss at the edge of the cover plate and a sharp decrease in the water-cement ratio, which in turn causes edge shrinkage cracks.

[0005] To achieve the above objectives, the energy-saving cement cover plate manufacturing curing device includes a conveying mechanism, a film-coating machine disposed on the top of the conveying mechanism, a film disposed on the film-coating machine, a cutter disposed on the film-coating machine, and a cover plate mold disposed on the conveying mechanism. The cover plate mold is provided with a side-covering mechanism for covering the side of the cover plate mold. The side-covering mechanism includes a front fixing component disposed on the front side of the cover plate mold, a triggering component disposed on the conveying mechanism, and side-covering components disposed on the other sides of the cover plate mold.

[0006] In the above technical solution, when the cover plate mold moves forward with the conveying mechanism, the end of the film in front of the cover plate mold is fixed to the front side of the cover plate mold by the front fixing component. As the cover plate mold continues to move forward, the film is pulled and laid on the top surface of the cover plate mold because the end of the film is fixed. Then the cutter cuts the film, and the side covering component fixes the hanging film from the other three side directions, covering the film on the four outer side walls of the cover plate mold so that the film physically blocks the gap between the edge of the cement cover plate and the side wall of the cover plate mold, ensuring that the edge of the cement cover plate is consistent with the center.

[0007] Based on the above, the front fixing component includes a rubber column fixedly installed on the front side of the cover plate mold and a conical spike fixedly installed at the front end of the rubber column; the side covering component includes multiple rotatable movable plates respectively disposed on the left side, right side and rear side of the cover plate mold.

[0008] The side covering assembly also includes connecting rods that are fixedly installed on the left, right and rear sides of the cover plate mold, and the movable plate rotates on the rod wall.

[0009] The movable plate consists of a first connecting part, a second connecting part, and a third connecting part.

[0010] The triggering component includes an extrusion block fixedly installed on the top surface of the conveying mechanism, a through groove opened on the front side of the cover plate mold, a trigger plate that is vertically and flexibly disposed inside the through groove and cooperates with the extrusion block, and a linkage assembly connecting the trigger plate and each movable plate.

[0011] The triggering component also includes a support roller that is rotatably mounted inside the laminator to support the film.

[0012] The linkage assembly also includes an installation groove that is opened inside the cover plate mold and communicates with the through groove, and a pressure plate that is fixedly installed on the outer wall of the trigger plate. When the trigger plate is separated from the extrusion block, the pressure plate presses down on the first connecting part of multiple movable plates.

[0013] The linkage assembly also includes a guide rod fixedly installed on the inner wall of the mounting groove and a slide groove opened on the outer wall of the pressure plate for the guide rod to slide.

[0014] The laminating machine is also equipped with a spraying mechanism inside.

[0015] The laminating machine is equipped with laminating rollers for guiding the film, and also has a pressing device inside.

[0016] The triggering component also includes a connecting plate rotatably mounted on the inner wall of the laminating machine and a rotating groove opened on the inner wall of the laminating machine for the support roller to slide, and the end of the connecting plate is sleeved on the support roller rod wall.

[0017] The triggering component also includes a torsion spring disposed between the connecting plate and the inner wall of the laminating machine.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this energy-saving curing device for cement cover plate manufacturing, the side-wrapping mechanism allows the film to not only cover the top surface of the cover plate mold but also wrap around the four outer side walls of the mold. This physically blocks the capillary siphon channels between the edge of the cement cover plate and the side walls of the mold, reducing heat loss from the mold side walls. This avoids excessively rapid local water loss at the edge of the cement cover plate and edge shrinkage cracks caused by a sharp decrease in the water-cement ratio, ensuring consistent humidity between the edge and center of the cement cover plate to guarantee molding quality. Simultaneously, it locks in the heat of cement hydration, achieving energy-saving curing.

[0019] 2. In this energy-saving cement cover plate manufacturing curing device, the extrusion block and trigger plate meet due to the forward movement of the cover plate mold along the conveying mechanism, generating extrusion force to temporarily fix and puncture the film. Furthermore, the gravity-induced descent of the trigger plate after it detaches from the extrusion block drives the pressure plate to press and rotate the movable plate, tightening the side film. This achieves the effect of automatically completing continuous sequential actions such as film front-end anchoring, pulling, laying, cutting, and simultaneous three-sided pressing without the need for additional complex power sources. This greatly simplifies the mechanical structure of the equipment, reduces the equipment failure rate and manufacturing cost, and improves the reliability of purely mechanical linkage operation.

[0022] 300. Spraying mechanism. Detailed Implementation

[0023] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] Therefore, addressing the problem that existing technologies, which only cover the top surface of the cement, cause capillary siphoning in the gaps between the cement sidewalls, resulting in excessively rapid local water loss and a sharp decrease in the water-cement ratio at the edge of the cover plate, thus leading to edge shrinkage cracks, this invention provides an energy-saving curing device for manufacturing cement cover plates. (Refer to...) Figure 1 As shown, the system includes a conveying mechanism 100, a laminating machine 101 mounted on top of the conveying mechanism 100, a film 103 mounted on the laminating machine 101, a cutter 106 mounted on the laminating machine 101, and a cover plate mold 105 mounted on the conveying mechanism 100. The cover plate mold 105 is equipped with a side-covering mechanism 200 for covering the sides of the cover plate mold 105. The side-covering mechanism 200 includes a front fixing assembly mounted on the front side of the cover plate mold 105, a triggering component mounted on the conveying mechanism 100, and side-covering assemblies mounted on the remaining sides of the cover plate mold 105. The lifting and lowering of the cutter 106 is controlled by a linear servo motor; when the film 103 needs to be cut, the cutter 106 is lowered. Furthermore, Figure 13 The text indicates that the conveying mechanism 101 in this device can also be used in conjunction with existing distance feeding devices or other devices.

[0025] It should be noted that the width of the film 103 is greater than the width of the cover mold 105, so that the film 103 can be covered on the four outer sides of the cover mold 105. By setting the side covering mechanism 200 on the cover mold 105, the film 103 can not only cover the top surface of the cement cover, but also wrap around the outer side wall of the cover mold 105, thereby physically blocking the capillary siphon channel between the edge of the cement cover and the side wall of the cover mold 105. This fundamentally avoids the problem of drying shrinkage cracks caused by excessive water loss at the edge of the cement cover. At the same time, by wrapping the side wall of the cover mold 105 with the film 103, the heat loss of the cover mold 105 is reduced, achieving energy-saving curing.

[0026] Combination Figure 5 and Figure 6 As shown, the side covering assembly includes multiple rotatable movable plates 213 respectively disposed on the left, right, and rear sides of the cover mold 105. The movable plates 213 are configured to rotate either from a position close to the side wall of the cover mold 105 to a position away from the side wall of the cover mold 105, or from a position away from the side wall of the cover mold 105 to a position close to the side wall of the cover mold 105. When the movable plates 213 rotate to fit against the side wall of the cover mold 105, they can tightly press the hanging film 103 onto the outer wall of the cover mold 105, achieving automatic edge sealing of the cover mold 105.

[0027] As the cover plate mold 105 moves forward with the conveying mechanism 100, the film 103 in front of the cover plate mold 105 is fixed to the front side of the cover plate mold 105 by the front fixing component. The cover plate mold 105 continues to move forward. Since the end of the film 103 is fixed, the film 103 is pulled and laid on the top surface of the cover plate mold 105. Then the cutter 106 cuts the film 103. Multiple movable plates 213 rotate towards the side wall of the cover plate mold 105 and fix the hanging film 103 from the other three side directions so that the film 103 covers the four outer side walls of the cover plate mold 105. This allows the film 103 to physically block the gap between the edge of the cement cover plate and the side wall of the cover plate mold 105, ensuring that the moisture content of the edge and center of the cement cover plate is consistent.

[0028] This equipment utilizes the power of the cover plate mold 105 itself as it moves forward with the conveyor mechanism 100, eliminating the need for an additional complex power source to drag the film 103. The front fixing component first anchors one end of the film 103. As the cover plate mold 105 moves forward, the film 103 is naturally laid flat and stretched on its top surface. After cutting, the movable plate 213 completes the synchronous pressing of the three sides.

[0029] according to Figure 4 As shown, the front fixing assembly includes a rubber post 207 fixedly installed on the front side of the cover plate mold 105 and a conical spike 208 fixedly installed on the front end of the rubber post 207. According to Figure 3 As shown, the triggering component includes an extrusion block 201 fixedly mounted on the top surface of the conveying mechanism 100, a through groove 209 formed on the front side of the cover plate mold 105, a trigger plate 210 vertically disposed inside the through groove 209 and cooperating with the extrusion block 201, and a linkage assembly connecting the trigger plate 210 and each movable plate 213. The triggering component also includes a support roller 205 rotatably mounted inside the laminating machine 101 for supporting the film 103.

[0030] It should be noted that the extrusion block 201 is stationary and fixed on the conveying path, while the trigger plate 210 moves with the cover plate mold 105. The mechanical extrusion force generated when the two meet becomes the sole power source for driving subsequent linkage actions. This method of triggering using relative motion is purely mechanical and extremely reliable. On the other hand, referring to... Figure 4 As shown, the mechanical extrusion force can temporarily fix the end of the film 103 so that the cone 208 can accurately pierce the film 103, effectively preventing the film 103 from being pushed by the cone 208 and failing to be pierced. The rubber column 207 can provide friction for the pierced end of the film 103, preventing the film 103 from detaching from the front side of the cover plate mold 105.

[0031] Furthermore, when the cover plate mold 105 arrives, the support roller 205 allows the end of the film 103 to fall onto the extrusion block 201, thereby ensuring that the film 103 is fixed to the front side of the cover plate mold 105 with the cooperation of the extrusion block 201, the trigger plate 210, the cone 208 and the rubber column 207. This ensures that the front anchor point of the film 103 will not fall off or tear when the cover plate mold 105 moves forward and pulls the film 103.

[0032] return Figure 5 and Figure 6 As shown, the side covering assembly also includes connecting rods 212 that are fixedly mounted on the left, right, and rear sides of the cover plate mold 105, respectively, and the movable plate 213 rotates on the rod wall of the connecting rods 212. The connecting rods 212 provide a cantilevered mounting base for the movable plate 213, allowing the movable plate 213 to have sufficient space for movement when rotating, and when pressing the film 103, the connecting rods 212 can provide stable support force to prevent the movable plate 213 from bending and deforming.

[0033] The movable plate 213 is composed of a first connecting part 216, a second connecting part 217, and a third connecting part 218. (Refer to...) Figure 7 The first connecting part 216 serves as the force-receiving end, receiving the downward pressure from the pressure plate 214. The second connecting part 217, as the rotating body, is connected to the connecting rod 212. It should be noted that the center of gravity of the second connecting part 217 is located on the outside of the connecting rod 212. Therefore, when the pressure plate 214 disengages from the first connecting part 216, the second connecting part 217 will rotate away from the cover plate mold 105 under the action of gravity. The third connecting part 218, as the actuating end, can directly act on the diaphragm 103. This structural design allows a small downward pressure to be converted into a large clamping force of the third connecting part 218 on the side wall.

[0034] The linkage assembly also includes a mounting groove 211 formed inside the cover plate mold 105 and communicating with the through groove 209, and a pressure plate 214 fixedly installed on the outer wall of the trigger plate 210, combined with Figure 8 As shown, when the trigger plate 210 disengages from the pressing block 201, the pressure plate 214 presses down on the first connecting part 216 of the plurality of movable plates 213.

[0035] Furthermore, combined Figure 11 and Figure 12 As shown, after the cover plate mold 105 passes the extrusion block 201, the extrusion block 201's extrusion force on the trigger plate 210 disappears, and the trigger plate 210 descends under the action of gravity. At this time, the pressure plate 214 descends accordingly and presses the first connecting part 216 of the multiple movable plates 213. It is by taking advantage of this gravity reset that the movable plates 213 are cleverly triggered to press against the side wall of the cover plate mold 105. The timing just matches the requirement of side wrapping after the film 103 is cut.

[0036] The linkage assembly also includes a guide rod 215 fixedly installed on the inner wall of the mounting groove 211 and a sliding groove formed on the outer wall of the pressure plate 214 for the guide rod 215 to slide. Further, refer to... Figure 8 and Figure 9 As shown, the sliding fit between the guide rod 215 and the slide groove provides strict trajectory restrictions for the up and down movement of the pressure plate 214, preventing the pressure plate 214 from deviating or jamming when pressing down on the first connecting part 216, thus ensuring the smoothness of the linkage mechanical transmission.

[0037] exist Figure 3 As shown, the laminating machine 101 also includes a spraying mechanism 300, which comprises multiple nozzles for spraying water or air. The spraying mechanism 300 sprays water or air onto the surface of the film 103 during the laminating process, increasing the adhesion between the film 103 and the cement surface and the sidewalls of the cover mold 105. This allows the film 103 to adhere more closely to the cover mold 105, further enhancing the airtight curing effect. It should be noted that the cement cover remains moist and fluid during the laminating process; the spraying mechanism 300 helps the film 103 adhere more closely to the surface of the cement cover, reducing the gaps between them.

[0038] exist Figure 3 The diagram also shows that the laminating machine 101 is internally equipped with a laminating roller 102 for guiding the film 103, and a pressure sheet 104 is also internally equipped with the laminating machine 101. The laminating roller 102 is used to guide the output direction of the film 103, ensuring that the film 103 enters the wrapping station in a flat state, while the pressure sheet 104 is used to prevent the film 103 from springing back when it is output, effectively preventing the film 103 from loosening and springing back after being stretched, causing wrinkles and affecting the sealing of the wrapping.

[0039] refer to Figure 1 and Figure 2 As shown, the triggering component also includes a connecting plate 202 rotatably mounted on the inner wall of the laminating machine 101 and a rotating groove 204 formed in the inner wall of the laminating machine 101 for the support roller 205 to slide, and the end of the connecting plate 202 is sleeved on the rod wall of the support roller 205. The triggering component also includes a torsion spring 203 disposed between the connecting plate 202 and the inner wall of the laminating machine 101.

[0040] Furthermore, the torsion spring 203 constantly applies a thrust to the connecting plate 202, causing the support roller 205 to tend to tension the film 103. This ensures that the film 103 pulled out and laid on the top surface of the cover mold 105 is always in a taut state, ensuring the flatness of the top surface coverage. The support roller 205 is not fixed, but is installed through a floating structure composed of the connecting plate 202, the rotating groove 204, and the torsion spring 203. When the film 103 is no longer pulled by the cover mold 105, the torsion spring 203 drives the support roller 205 back to its initial position, thereby enabling the support roller 205 to drive the film 103 back onto the extrusion block 201.

[0041] Working principle: Combination Figure 4 As shown, when the cover plate mold 105 moves forward with the conveyor mechanism 100 to the film coating station, the end of the film 103, supported by the support roller 205, falls onto the stationary extrusion block 201. As the cover plate mold 105 continues to move forward, the follow-up trigger plate 210 meets the extrusion block 201 and generates mechanical extrusion force, temporarily clamping and fixing the film 103 between them. This extrusion force causes the film 103 to accurately adhere to and pierce the conical puncture 208 of the front fixing component. After being punctured, the film 103 is firmly anchored to the front side of the cover plate mold 105 under the friction clamping of the rubber column 207.

[0042] Combination Figure 11 As shown, the cover plate mold 105 continues to move forward. Since the front end of the film 103 has been anchored, the film 103 is pulled and laid flat and taut on the top surface of the cover plate mold 105. During this pulling process, the floating tensioning structure composed of the connecting plate 202, the rotating groove 204, and the torsion spring 203 ensures that the support roller 205 always provides tension to the film 103, ensuring that the top surface is laid flat. After the film 103 completely covers the top surface, the cutter 106 cuts the film 103.

[0043] When the cover plate mold 105 passes the extrusion block 201, the extrusion pressure disappears, and the trigger plate 210 descends and resets along the through groove 209 under gravity. At this time, the pressure plate 214 fixed on the trigger plate 210 descends along the guide rod 215, pressing the first connecting part 216 of each movable plate 213. Figure 12 As shown, this causes the movable plate 213 to overcome the center of gravity and rotate around the connecting rod 212 toward the side wall of the cover plate mold 105. Its third connecting part 218 presses the hanging film 103 tightly onto the other three outer side walls of the cover plate mold 105, thereby completing the full coverage and sealing of the four sides of the cover plate mold 105 by the film 103.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
