Description

Technical Field

[0001] This utility model relates to the technical field of precast panel production equipment, specifically to a precast panel elastic flattening mechanism. Background Technology

[0002] Wall panels are usually prefabricated using concrete or other mortar with added fiber materials, allowing for direct on-site installation, which is very convenient.

[0003] To improve the surface quality of precast slabs, surface leveling devices are commonly used during the molding process. For example, a precast slab vibration leveling device with application number CN202120041028.5 provides a surface leveling device for improving the surface quality of precast slabs. It includes a slide rail, on which a translation trolley is slidably connected. The translation trolley is connected to a horizontally set leveling rod via a hanger. The leveling rod is a long rectangular plate. The precast slab is located under the leveling rod. By sliding the translation trolley on the slide rail, the leveling rod is driven to flatten the upper surface of the precast slab. The lower side and adjacent four-sided sidewalls of the leveling rod can also be detachably connected to a protective layer covering the surface of the leveling rod. These protective layers are fixed by clamps, so that the protective layer with adhering mud can be replaced after the flattening operation is completed.

[0004] However, the above-mentioned leveling device still has the following defects in use: during the leveling operation on the surface of the precast slab, the mud adhering to the protective layer will gradually solidify, and long-term use will affect the leveling quality. Therefore, the protective layer needs to be replaced frequently. The process of disassembling and assembling the protective layer will reduce work efficiency, and the mud adhering to the replaced protective layer is difficult to remove. Recycling the protective layer requires more steps, which further reduces work efficiency. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a precast panel elastic flattening mechanism.

[0006] The technical solution of this utility model is as follows:

[0007] A precast slab elastic flattening mechanism includes a movable frame and a flattening unit mounted thereon, which can flatten the upper surface of the precast slab. The flattening unit includes a flattening roller arranged horizontally and a scraper elastically arranged on one side of the flattening roller. The flattening roller is vertically elastically connected to the movable frame, and the direction of the elastic force on the flattening roller is downward. The scraper elastically fits against the flattening roller and its length is not less than the length of the flattening roller.

[0008] In use, the moving frame drives the flattening unit to move. At this time, the flattening roller contacts the upper surface of the precast slab and flattens the upper surface of the precast slab during the movement. Under the action of the scraper, the mud adhering to the flattening roller can be scraped off during the movement of the flattening roller. This flattening mechanism does not require any additional operation steps to remove the mud adhering to the flattening roller. Instead, the mud is scraped off by the rotation of the flattening roller during its movement. This design optimizes the working steps and greatly improves the working efficiency.

[0009] The design of the vertical elastic connection between the flattening roller and the moving frame ensures that the flattening roller can automatically adjust the flattening height according to the unevenness of the surface of the precast slab, thereby avoiding the surface roughness caused by pushing the protrusions flat all at once. This design helps to improve the quality of the product.

[0010] As a further implementation, the scraper is located on the upper side of the flattening roller. When the flattening roller presses the precast slab downward under the action of elastic force, the flattening roller will move upward due to the action of the reverse force. At this time, the scraper located on the upper side can fit more tightly on the flattening roller, thereby more effectively scraping off the mud adhering to the surface of the flattening roller.

[0011] Furthermore, the magnitude of the elastic force on the flattening roller is adjustable, and the vertical height of the flattening roller is adjustable. By adjusting the vertical height and the magnitude of the elastic force on the flattening roller, the flattening roller can maintain effective contact with the upper surface of precast slabs of different thicknesses or hardnesses through the above two adjustments, so as to adapt to the flattening mechanism to flatten precast slab materials of different thicknesses and hardnesses.

[0012] The elastic force on the scraper is adjustable, so that the scraping force can be adjusted according to actual needs, ensuring the scraping effect while avoiding damage to the surface of the flattening roller.

[0013] As a further implementation, the mobile frame includes a main frame and two upright plates arranged opposite each other on it. Two sets of flattening units are arranged side by side between the two upright plates. The surface of the precast plate is flattened twice by the two sets of flattening units, which reduces the time required for flattening once and improves work efficiency.

[0014] Furthermore, two support members are arranged horizontally between the two upright plates, spaced vertically. A screw rod is vertically arranged on the upper side of the scraper, passing through the two support members. A spring is fitted on the screw rod between the two support members. Locking nuts are connected to the screw rods on the upper side of the two support members. In use, the scraper can move downwards or downwards without changing the magnitude of the elastic force by simultaneously adjusting the two locking nuts upwards or downwards. Alternatively, the spring can be compressed by adjusting one of the locking nuts individually, increasing or decreasing the magnitude of the elastic force on the scraper to adapt to different usage requirements and maintain the elastic fit between the scraper and the flattening roller.

[0015] Furthermore, the vertical height of the upper support is adjustable, while the lower support is fixed to the upright plate. The adjustable vertical height of the upper support allows for quick adjustment of the fit between the scraper and the flattening roller, improving adjustment efficiency.

[0016] There are at least two types of scraper structures. The first type is that the scraper includes an angle iron, with its two sides contacting the two sides of the flattening roller along its length. The second type is that the scraper has a notch on its lower side that fits against the upper side of the flattening roller, and the two outer sides of the notch are tangent to the two sides of the flattening roller. Both of these methods can achieve bidirectional scraping, that is, when the flattening unit moves in two directions to perform flattening operations, and the flattening roller rotates in opposite directions, the scraper that is elastically fitted with the flattening roller can effectively scrape the flattening roller.

[0017] The beneficial effects of this utility model are that by moving the moving frame to drive the flattening unit to move, the flattening roller can flatten the upper surface of the precast slab during its movement. At the same time, under the action of the scraper, the mud adhering to the flattening roller can be scraped off during the movement of the flattening roller. This flattening mechanism does not require any additional operation steps to scrape off the mud adhering to the flattening roller. Instead, the mud scraping is automatically completed during the movement of the flattening roller. This design optimizes the working steps and greatly improves the working efficiency.

[0026] Combination Figure 1 and Figure 3 This embodiment provides a precast panel elastic flattening mechanism, including a movable frame 1 and a flattening unit installed on it that can flatten the upper surface of the precast panel.

[0027] The movable frame 1 is used to support the flattening unit and drive the flattening unit to move, thereby completing the flattening work during the movement of the flattening unit.

[0028] Regarding the structure of the flattening unit, combined with Figure 1 and Figure 3 Specifically, the flattening unit includes a flattening roller 2 arranged horizontally and a scraping module 4. The flattening roller 2 is used to flatten the upper surface of the precast slab, and the scraping module 4 is used to scrape off the mud adhering to the surface of the flattening roller 2 during the flattening operation. The scraping module 4 includes a scraper 41 elastically arranged on one side of the flattening roller 2. The flattening roller 2 is vertically elastically connected to the moving frame 1 and the direction of the elastic force is downward. The scraper 41 is elastically attached to the flattening roller 2 and its length is not less than the length of the flattening roller 2, so as to better scrape off the mud on the entire outer surface of the flattening roller 2.

[0029] The core technical concept of this utility model is that the flattening roller 2 is vertically elastically connected to the moving frame 1, and the direction of the elastic force is downward. The scraper 41 is elastically attached to the flattening roller 2, and its length is not less than the length of the flattening roller 2. This makes it possible to remove the mud adhering to the flattening roller 2 during the working process without any additional operation steps. Instead, the mud adhering to the surface of the flattening roller 2 is scraped off by the scraper 41 during the movement of the flattening roller 2. This design optimizes the working steps and greatly improves the working efficiency.

[0030] The design of the vertical elastic connection between the pressing roller 2 and the moving frame 1 ensures that the pressing roller 2 can automatically adjust the pressing height according to the unevenness of the surface of the precast board, thereby avoiding the surface roughness caused by pushing the protrusions flat all at once. This design helps to improve the quality of the product.

[0031] In this embodiment, the mobile frame 1 includes a main frame and two upright plates 11 arranged opposite to each other. Two sets of flattening units are arranged side by side between the two upright plates 11. The surface of the precast plate is flattened twice by the two sets of flattening units, which reduces the time required for flattening once and improves the overall flattening speed.

[0032] The magnitude of the elastic force on the flattening roller 2 is adjustable, and the vertical height of the flattening roller 2 is also adjustable. By adjusting the vertical height of the moving frame 1 and the magnitude of the elastic force on the flattening roller 2, the flattening roller 2 can maintain effective contact with the upper surface of precast slabs of different thicknesses or hardnesses. This allows the flattening mechanism to flatten precast slab materials of different thicknesses and hardnesses, thus increasing the applicability of the flattening mechanism.

[0033] The magnitude of the elastic force on the flattening roller 2 is adjustable, specifically in conjunction with... Figure 2 For example, a horizontal plate 14 is arranged horizontally on one side of the upright plate 11. A vertical slot 111 is provided at the lower part of the upright plate 11. The two ends of the flattening roller 2 are vertically elastically connected to the horizontal plate 14 through the slot 111 via a connecting assembly 3. The connecting assembly 3 includes a horizontal bar 31 rotatably connected to both ends of the flattening roller 2 and provided through the slot 111. A first screw 32 is vertically connected to the outer end of the horizontal bar 31. A spring is sleeved on the first screw 32, and the upper end of the first screw 32 passes through the horizontal plate 14 and is threadedly connected to a locking element. The locking element here is a locking nut. By adjusting the position of the locking nut on the first screw 32, the magnitude of the elastic force on the flattening roller 2 is adjusted.

[0034] The vertical height of the flattening roller 2 is adjustable. Specifically, mounting plates are horizontally provided on both sides of the length of the two vertical plates 11. A mounting seat is provided on the lower side of the mounting plate. An opening is provided on the lower side of the mounting seat. A roller is rotatably installed in the opening. The mounting plate and the mounting seat are connected by screws. Nuts are provided on the screws located on the upper and lower sides of the mounting plate. The vertical height of the two vertical plates 11 can be adjusted by adjusting the two nuts, thereby adjusting the vertical height of the flattening roller 2. When flattening precast slabs of the same thickness but different hardness, it is necessary to adjust the magnitude of the elastic force and the vertical height of the flattening roller 2 at the same time so that the flattening roller 2 can maintain effective contact with the upper surface of the precast slab, thus adapting to the leveling work of precast slab materials of different thicknesses and hardnesses.

[0035] In this embodiment, the elastic force on the scraper 41 is adjustable, so as to adjust the scraping force of the scraper 41 according to actual needs, ensuring the scraping effect while avoiding damage to the surface of the flattening roller 2.

[0036] Combination Figure 1The scraper 41 is located on the upper side of the flattening roller 2. When the flattening roller 2 presses the precast plate downward under the action of elastic force, the flattening roller 2 will move upward due to the action of reverse force. At this time, the scraper 41 located on the upper side can fit more tightly on the flattening roller 2, thereby more effectively scraping off the mud adhering to the surface of the flattening roller 2.

[0037] The magnitude of the elastic force on the scraper part 41 is adjustable, depending on the specific combination. Figure 3 Specifically, two horizontally spaced support members are provided between the two upright plates 11. The two support members are an adjusting plate and a fixing plate 12, which are arranged vertically. One fixing plate 12 is horizontally provided on each side of the scraper 41, and both ends are fixedly connected to the two upright plates 11. The upper side of the scraper 41 is provided with a vertically extending screw that passes through the fixing plate 12 and the adjusting plate in sequence. This screw is the second screw 42, and a spring is sleeved on the second screw 42 between the fixing plate 12 and the adjusting plate. Locking nuts are connected to the second screw 42 located on the upper side of the adjusting plate and the fixing plate 12. In use, to maintain the elastic fit between the scraper 41 and the flattening roller 2, the two locking nuts can be adjusted simultaneously upwards or downwards. The scraper 41 can move downwards or downwards without changing the magnitude of the elastic force, thus maintaining the elastic fit between the scraper 41 and the flattening roller 2. Alternatively, one locking nut can be adjusted individually to compress the spring, increasing or decreasing the elastic force on the scraper 41. The purpose is to maintain the elastic fit between the scraper 41 and the flattening roller 2 by adjusting the scraper 41 in conjunction with the flattening roller 2.

[0038] To improve the stability of the scraper 41, several second screws 42 are provided along the length of the scraper 41. Preferably, two second screws 42 are provided at intervals along the length of the scraper 41.

[0039] In this embodiment, the vertical height of the upper support member is adjustable, that is, the vertical height of the adjustment plate is adjustable. The lower support member is fixed to the upright plate 11, that is, the fixing plate 12 is fixed to the upright plate 11. Through the design of adjustable vertical height of the adjustment plate, the contact state between the scraper 41 and the flattening roller 2 can be quickly adjusted.

[0040] Specifically, the adjusting plate includes a sliding plate 13 located between two fixed plates 12. The two ends of the sliding plate 13 are in vertical sliding contact with the two upright plates 11. Support plates are horizontally provided on both sides of the sliding plate 13 corresponding to the four second screws 42 on the two scraper components 41. The upper ends of the four second screws 42 pass vertically through the corresponding support plates, and two locking nuts are respectively provided on the support plates and the second screws 42 on the upper side of the fixed plates 12. A connecting plate is provided at the upper end of the two upright plates 11 corresponding to the position of the sliding plate. An adjusting rod is vertically threaded in the middle of the connecting plate, and two adjusting rods are spaced apart. The lower end of the adjusting rod is rotatably connected to the sliding plate, and the upper end extends out of the connecting plate and is locked with a nut. By rotating the adjusting rod, the sliding plate is driven to move the support plates on both sides vertically, thereby realizing the movement of the scraper components 41 on both sides. The contact state between the scraper components 41 on both sides and the flattening roller 2 can be quickly adjusted, improving the adjustment efficiency.

[0041] In accordance with the above design, in Embodiment 1, the scraper 41 includes an angle iron, the two sides of which respectively contact the two sides of the flattening roller 2 along its length, as shown below. Figure 4 As shown.

[0042] In embodiment 2, the lower side of the scraper 41 has a notch that fits against the upper side of the flattening roller 2, and the two outer sides of the notch are tangent to the two sides of the flattening roller 2, as shown below. Figure 5 As shown.

[0043] Both of the above-described embodiments of the scraper 41 can achieve bidirectional scraping of the flattening roller 2. That is, when the flattening unit moves in two directions to perform flattening operations, and the rotation direction of the flattening roller 2 is opposite, the scraper 41 that is elastically attached to the flattening roller 2 can effectively scrape the flattening roller 2.

[0044] In use, this flattening mechanism spans both sides of a rectangular mold. The rectangular mold is filled with slurry for making precast slabs. By pushing the moving frame 1, the flattening unit moves along the length of the mold. At this time, the flattening roller 2 contacts the upper surface of the precast slab (the upper layer of slurry for making precast slabs) inside the rectangular mold, and flattens the upper surface of the precast slab during the movement. Under the action of the scraper 41, the slurry adhering to the flattening roller 2 can be scraped off during the flattening roller 2 movement. This flattening mechanism does not require any additional operation steps to specifically clean the slurry adhering to the flattening roller 2. Instead of scraping off the attached mud, the mud scraping is automatically completed during the movement of the flattening roller 2. This design optimizes the work steps and greatly improves work efficiency. At the same time, the horizontal height position and elastic force of the flattening roller 2 and the scraper 41 can be adjusted by adjusting the adjusting rods or screws to adapt to the flattening work of precast slab materials with different thicknesses and hardnesses, thus improving the applicability of this flattening mechanism. After the above flattening work is completed, the upper surface of the precast slab is dried, and the final precast slab can be directly installed on site.
