Description
Technical Field
[0001] The utility model relates to the technical field of precast wallboard production equipment, in particular to a flattening mechanism with wide applicability. Background Technique
[0002] In the production process of precast wallboards, after mixing slurries such as cement and gypsum with fiber reinforcing materials and injecting them into a mold, the upper surface of the precast wallboard is uneven. To ensure the surface quality of the precast board, it needs to be flattened.
[0003] For the surface flattening operation of precast wallboards, it is usually completed by manually lifting a flat plate and making a horizontal flattening movement on the upper surface of the precast wallboard. However, for those parts with higher protrusions, flattening them at one time may cause the surface to be rough. Therefore, workers usually flatten the protrusions in multiple times to avoid this problem. And before each flattening, the height of the flat plate needs to be readjusted manually, and the flat plate needs to be kept horizontal during the flattening process. This process not only takes time but also easily makes workers feel fatigued, thereby reducing the production efficiency. Obviously, this operation not only requires workers to have relatively high experience, but also the process is cumbersome and not applicable to the flattening operations of precast wallboards with different thicknesses. Content of the Utility Model
[0004] To solve the technical problems existing in the above background technique, the utility model provides a flattening mechanism with wide applicability.
[0005] The technical solution of the utility model is as follows:
[0006] A flattening mechanism with wide applicability includes a table body and guide rails on its upper side, and a flattening main body is slidably arranged through the guide rails. The flattening main body includes a moving frame slidably arranged on the guide rails and a flattening roller horizontally arranged thereon. The flattening roller is vertically elastically connected to the moving frame, the direction of the elastic force it receives is downward, and the magnitude of the elastic force it receives is adjustable, and the vertical height of the flattening roller is adjustable. The design of this flattening mechanism replaces manual labor, reduces the labor intensity of workers, and thus improves work efficiency.
[0007] During use, place the mold on the table body inside the two guide rails, then adjust the magnitude of the elastic force received by the flattening roller according to the materials for making the precast wallboard in the mold, and adjust the vertical height of the moving frame so that the flattening roller is at a preset flattening height. Then, push the flattening main body to move along the length direction of the guide rails. At this time, the flattening roller contacts the upper surface of the precast wallboard in the rectangular mold (the upper layer of the slurry for making the precast wallboard), and flattens the upper plane of the precast wallboard during the movement.
[0008] The core technical concept of the present utility model lies in that the flattening roller is vertically elastically connected to the moving frame, the direction of the elastic force it receives is downward, and the magnitude of the elastic force is adjustable, and the vertical height of the flattening roller is adjustable. The design of the vertical elastic connection between the flattening roller and the moving frame enables the flattening roller to be adaptively adjusted according to different protrusion heights during the flattening process, thus avoiding the problem of surface roughness caused by pushing down the protrusions at one time. This design helps to improve the flattening quality. Combining the design that the magnitude of the elastic force received by the flattening roller is adjustable and the vertical height is adjustable, the present flattening mechanism can be applied to the leveling work of precast wall panels with different thicknesses.
[0009] As a further implementation method, at least two flattening rollers are arranged in parallel. The upper surface of the precast wall panel is flattened twice by the two flattening rollers successively, which reduces the time required for a single flattening roller to level once, thus improving the work efficiency. Moreover, the magnitudes of the elastic forces received by the two flattening rollers can also be designed to be adjustable respectively, so as to adjust the magnitudes of the elastic forces received by the two flattening rollers respectively according to needs, expanding the applicability of the present flattening mechanism.
[0010] For a flattening mechanism with wide applicability as described above, two guide rails are arranged in parallel. The guide rails include strip-shaped baffles whose planes are vertical. At the lower ends of the sides of the two guide rail baffles facing away from each other, there are connecting plates fixed to the upper surface of the table body. During use, in order to facilitate the removal of the precast wall panel after molding in the later stage, the two guide rail baffles can be used to replace the two side rods of the rectangular mold, and then the slurry for making the precast wall panel is directly filled onto the upper surface of the table body between the two baffles, so that the flattening main body can perform a flattening operation on the upper surface of the precast wall panel.
[0011] Specifically, the moving frame includes a main frame, two relatively arranged vertical plates on it, and a horizontal plate horizontally arranged on one side of the vertical plates. There are long openings vertically arranged on the vertical plates, and both ends of the flattening roller pass through the long openings and are vertically elastically connected to the horizontal plate.
[0012] Furthermore, both ends of the flattening roller are elastically connected to the horizontal plate through vertically arranged support rods. The lower end of the support rod is rotatably connected to the flattening roller, a spring is sleeved on it, and the upper end passes through the horizontal plate and is threadedly connected with a locking member.
[0013] To prevent interference between the vertical plates and the two sides of the precast wall panel during the flattening process, the two vertical plates are respectively arranged outside the two guide rail baffles, and rollers in rolling contact with the baffles are arranged on the inner sides of the lower parts of the vertical plates.
[0014] As a further implementation method, a scraper elastically attached to the upper side of the flattening roller is also provided. During the process of flattening the upper plane of the precast wall panel by the flattening roller, the mud adhered to the flattening roller can be scraped off under the action of the scraper. This flattening mechanism does not require other additional operation steps to remove the mud adhered to the flattening roller. Instead, during the movement of the flattening roller, the rotation of the flattening roller is used to complete the scraping of the mud. Such a design optimizes the working steps, greatly improves the working efficiency, and effectively prevents the risk that the mud adhered to the flattening roller may solidify on the flattening roller and be difficult to remove due to untimely scraping.
[0015] Furthermore, the magnitude of the elastic force received by the scraper is adjustable to be adjusted in coordination with the adjustment of the flattening roller, and always maintain elastic attachment to the flattening roller, effectively completing the scraping work of the mud on the flattening roller during the flattening process.
[0016] To prevent the flattening main body from detaching from the two guide rails, roller limiting rods are also provided at both ends of the table body, which are horizontally arranged between the two guide rails, so that the flattening main body can only move on the guide rails between the two roller limiting rods and will not detach from the two guide rails.
[0017] The beneficial effect of a widely applicable flattening mechanism of the present utility model lies in that the design of vertically elastically connecting the flattening roller and the moving frame in this flattening mechanism enables the flattening roller to be adaptively adjusted according to different protrusion heights during the flattening process, thereby avoiding the problem of rough surface caused by pushing down the protrusions at one time. This design helps to improve the flattening quality, and combined with the design that the magnitude of the elastic force received by the flattening roller is adjustable and the vertical height of the moving frame is adjustable, this flattening mechanism can be applied to the leveling work of precast wall panels with different thicknesses.

[0026] Combined with Figure 1 , this embodiment provides a flattening mechanism with wide applicability, including a table body 1 and a guide rail 2 on its upper side, and a flattening main body is slidably arranged through the guide rail 2. The two guide rails 2 are used to support the flattening main body and provide guidance for the movement of the flattening main body. The flattening main body is used to flatten the precast wall panel during the movement process.
[0027] Combined with Figure 1 and Figure 3 , the flattening main body includes a moving frame 32 slidably arranged on the guide rail, and a pressing unit 3 arranged thereon for flattening the precast wall panel.
[0028] The core technical concept of the present utility model is that the pressing unit 3 includes a flattening roller 2 horizontally arranged on the moving frame 32. The flattening roller 2 is vertically elastically connected to the moving frame 32. The direction of the elastic force it receives is downward, and the magnitude of the elastic force it receives is adjustable. Moreover, the vertical height of the flattening roller 2 is adjustable. The design of the vertical elastic connection between the flattening roller 31 and the moving frame 32 enables the flattening roller 31 to be adaptively adjusted according to different protrusion heights during the flattening process, thereby avoiding the problem of rough surface caused by pushing the protrusion flat at one time. This design helps to improve the flattening quality. And combined with the design that the magnitude of the elastic force received by the flattening roller 31 is adjustable and the vertical height is adjustable, this flattening mechanism can be applied to the leveling work of precast wall panels with different thicknesses.
[0029] Combined with Figure 3 and Figure 4 , the moving frame 32 includes a main frame, two opposite vertical plates arranged thereon, and a cross plate 34 horizontally arranged on one side of the vertical plates. A long opening 321 is vertically arranged on the vertical plates. Both ends of the flattening roller 2 pass through the long opening 321 and are vertically elastically connected to the cross plate 34.
[0030] Specifically, both ends of the flattening roller 2 are elastically connected to the cross plate 34 through vertically arranged support rods 33. A cross bar is vertically arranged at the lower end of the support rod 33, and the cross bar is rotationally connected to the flattening roller 2. A spring is sleeved thereon, and the upper end passes through the cross plate and is threadedly connected with a locking member, and the locking member is a locking nut.
[0031] In the present embodiment, two flattening rollers 31 are arranged in parallel, and the upper surface of the prefabricated wall panel is flattened twice in succession by the two flattening rollers 31, thereby reducing the time required for a single flattening roller 31 to level the surface, thereby improving work efficiency. In addition, the magnitude of the elastic force exerted on the two flattening rollers 31 is adjustable, so that the magnitude of the elastic force exerted on the two flattening rollers 31 can be adjusted separately according to needs, thereby expanding the applicability of the flattening mechanism.
[0032] like Figure 4 As shown, two guide rails 2 are provided in parallel, and the guide rails 2 include vertical strip baffles in the plane where they are located. The lower ends of the baffles of the two guide rails 2 on the side facing away from each other are provided with connecting plates fixed to the upper surface of the platform 1. When in use, in order to facilitate the removal of the prefabricated wall panels after forming in the later stage, the baffles of the two guide rails 2 can be used to replace the two side rods of the rectangular mold, and then the slurry for making the prefabricated wall panels can be directly filled into the upper surface of the platform 1 between the two baffles, so that the flattening body can flatten the upper surface of the prefabricated wall panels.
[0033] Among them, the connecting plate and the platform body 1 are detachably connected by connecting bolts to facilitate the replacement of the guide rail 2. The two vertical plates are respectively arranged on the outer sides of the baffles of the two guide rails 2, and the inner side of the lower part of the vertical plate is provided with a roller 37 that is in rolling contact with the baffle. The roller 37 is a T-shaped track wheel, and the diameter of the roller 37 located on the outer side of the vertical surface of the guide rail 2 is larger than the diameter of the roller 37 located on the inner side of the vertical surface of the guide rail 2.
[0034] Specifically, connecting plates 35 are provided on both sides of the vertical plate in the length direction, and a mounting seat 36 is provided on the lower side of the connecting plate 35. The mounting seat 36 is a U-shaped structure with an opening facing downward. The roller 37 is rotatably arranged in the opening on the lower side of the mounting seat 36. The horizontal plane height of the lower side of the mounting seat 36 is lower than the horizontal plane height of the lower side of the roller 37. A screw rod 42 passing through the connecting plate 35 is vertically provided on the upper side of the mounting seat 36, and nuts are provided on the screw rods 42 located on the upper and lower sides of the connecting plate 35. The vertical height of the vertical plate can be adjusted by adjusting the positions of the two nuts.
[0035] When in use, two guide rails 2 can be used to replace the two side rods of the mold, and then the slurry for making the prefabricated wall panels can be directly filled into the upper surface of the table 1 between the two guide rails 2, and then the flattening body can be pushed along the two guide rails 2 to flatten the upper surface of the prefabricated wall panels, and the vertical plates are located on the outside of the guide rails 2 to prevent the vertical plates from interfering with the two sides of the prefabricated wall panels during the flattening process. Here, due to the rolling contact between the roller 37 and the upper end of the guide rail 2, the upper end horizontal plane of the prefabricated wall panel is lower than the upper end horizontal plane of the guide rail 2, and the roller 37 is in rolling contact with the upper end of the guide rail 2 during flattening, so the movement of the roller 37 will not interfere with the prefabricated wall panel.
[0036] Combination Figure 1 Roller limiting rods are also provided at both ends of the platform body 1, which are transversely arranged between the two guide rails 2, so that the flattening body can only move on the guide rails 2 between the two roller limiting rods and will not leave the two guide rails 2.
[0037] Combined with Figure 1 and Figure 2 , the flattening body further includes a scraping unit 4 for scraping the mud adhering to the outer surface of the flattening roller 31 during the flattening process.
[0038] As Figure 2 shown, the scraping unit 4 includes a scraper 41 disposed above the flattening roller 31 and elastically attached to the flattening roller 31. Through the design of the scraper 41, this flattening mechanism does not require other additional operating steps to remove the mud adhering to the flattening roller 31. Instead, during the movement of the flattening roller 31, the rotation of the flattening roller 31 is used to complete the scraping of the mud. Such a design optimizes the working steps, greatly improves the working efficiency, and effectively prevents the situation where the mud adhering to the flattening roller 31 may solidify on the flattening roller 31 and is difficult to remove due to untimely scraping.
[0039] Combined with Figure 5 ,the scraper 41 is an angle iron, and its two side edges are respectively in contact with the two sides in the length direction of the flattening roller 31. The scraper 41 can achieve two-way scraping of the flattening roller 31, that is, when the flattening unit moves in two directions for flattening operations, the rotation direction of the flattening roller 31 is opposite. At this time, both sides of the scraper 41 can effectively scrape the flattening roller 31.
[0040] In this embodiment, the magnitude of the elastic force received by the scraper 41 is adjustable to be adjusted in cooperation with the adjustment of the flattening roller 31, and always maintain elastic attachment to the flattening roller 31, effectively completing the scraping work of the mud on the flattening roller 31 during the flattening process.
[0041] Specifically, a fixing plate 43 is horizontally provided between the two vertical plates. Two fixing plates 43 are respectively provided on the upper side of the scraper 41. The two ends of the two fixing plates 43 are fixedly connected to the two vertical plates. An adjusting member 44 is further provided inside the two fixing plates 43. The adjusting member 44 includes a U-shaped plate with an upward opening and horizontal support plates extending outward from its two sides. The vertical height of the U-shaped plate is adjustable, and the two ends of the U-shaped plate are vertically slidably connected to the two vertical plates. A screw 42 passing through the fixing plate 43 and the support plate is vertically provided on the upper side of the scraper 41, and a spring is sleeved on the screw 42 between the fixing plate 43 and the support plate. Adjusting nuts are connected to the screw 42 above the fixing plate 43 and the support plate. When in use, by simultaneously adjusting the two adjusting nuts upward or downward, the scraper 41 can move downward or upward without changing the magnitude of the elastic force received; by individually adjusting one of the locking nuts, the spring is compressed to increase or decrease the magnitude of the elastic force received by the scraper 41 to adapt to different usage requirements, aiming to keep the scraper 41 elastically attached to the flattening roller 31.
[0042] Combined with Figure 5, a support rod 33 is connected between the two sides of the upper end opening of the U-shaped plate. A fixing rod is also horizontally arranged between the two vertical plates. The fixing rod is located below the support rod 33 inside the U-shaped plate. The middle part of the support rod 33 is vertically and spirally connected with an adjusting rod 45. The lower end of the adjusting rod 45 passes through the support rod 33 and is rotatably connected with the fixing rod. The upper end is provided with a rotating handle. And a locking nut is arranged on the adjusting rod 45 above the support rod 33. When it is necessary to adjust the flattening roller 31, in order to facilitate the adjustment, it is necessary to release the elastic fitting state between the scraping plate 41 and the flattening roller 31. At this time, by rotating the rotating handle, the U-shaped plate drives the support plates on both sides to move vertically upward, and then drives the two scraping plates 41 to move upward away from the flattening roller 31, realizing the rapid adjustment of the scraping plate 41; after the adjustment of the flattening roller 31 is completed, by rotating the rotating handle in the reverse direction, the U-shaped plate drives the support plates on both sides to move vertically downward, and then drives the two scraping plates 41 to move downward close to the flattening roller 31, so as to quickly realize the elastic fitting between the scraping plate 41 and the flattening roller 31.
[0043] It can be understood that one end of the upper surface of the frustum 1 is the mold placement area, and the other end is the flattening main body placement area. When the flattening main body completes the flattening work in the mold placement area, it can move to the placement area and stop, so as to facilitate the disassembly of the prefabricated plate in the mold placement area.
[0044] In the actual operation process, when there are pits on the upper surface of the prefabricated wall panel, sometimes it is necessary to flatten it multiple times to achieve the flattening effect. Therefore, the operator may deliberately add more slurry into the mold to improve the flattening efficiency. In order to cope with this situation, on the frustum 1 between the two guide rails 2 in the placement area, an installation opening is also provided. A receiving hopper is arranged in the installation opening. Here, in order to highlight the structure of the flattening main body on the frustum, the installation opening and the receiving hopper are not shown in the drawings. During the process of the flattening main body moving from the mold placement area to the placement area for flattening, the excess slurry will move towards one end of the placement area under the push of the flattening roller 31, and finally be pushed into the receiving hopper. The receiving hopper collects the excess slurry, so that it can be used again, reducing the waste of materials.
