Detailed implementation manners

[0030] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0031] See Figures 1 - 3 As shown, a concrete surface film covering device with a leveling function includes a leveling plate 1, a handle 2 rotatably arranged on the leveling plate 1, a film covering rotating roller 3 installed on the leveling plate 1, a mounting block 4 arranged on the leveling plate 1 and used for installing the film covering rotating roller 3, a second rotating roller 5 rotatably arranged on the leveling plate 1 for covering the leveled concrete, and a contact rotating mechanism 6 rotatably arranged on the leveling plate 1 for contacting the concrete. The contact rotating mechanism 6 includes a roller 61 and a rotating scraping plate 62, and a transmission mechanism 7 for driving the rotating scraping plate 62 to rotate. The concrete surface film covering device with a leveling function further includes a linkage contact cutting mechanism 8 slidably arranged in the vertical direction on the handle 2 and used for performing contact cutting treatment on the film covering rotating roller 3. The roller 61 is preferably made of nylon material, which is relatively light in weight, has good self-lubricity and a low friction coefficient, and is convenient for improving the service life of the roller 61. The handle 2 is a telescopic handle 2 and has the function of adjustable length.

[0032] When the concrete surface needs to be evenly smoothed, the user first holds the handle 2, and then uses the handle 2 to pull the grinding plate 1. During this process, the grinding plate 1 can slide on the concrete through the rotation of the roller 61. During this process, when the roller 61 rotates, the rotational movement of the roller 61 can be converted into the rotational movement of the rotating scraper plate 62 through the transmission mechanism 7. Since the rotating scraper plate 62 is arranged in front of the grinding plate 1, the rotating scraper plate 62 can rotate when the grinding plate 1 is pulled, and then the front of the grinding plate 1 can be rotated and evenly scraped in advance. When the rotating scraper plate 62 rotates, the garbage attached to the concrete surface can also be removed, which further improves the smoothing effect of the grinding plate 1 and reduces the user's labor time in disguise.

[0033] See also Figure 3 and Figure 4 As shown, the transmission mechanism 7 includes a rotating rod 71, a worm 72, a rotating rod 73 and a turbine 74; the rotating rod 71 is rotatably set on the grinding plate 1 and is coaxially fixed with the roller 61; the worm 72 is set on the rotating rod 71 and has a plurality of parts, and the worm 72 is coaxially fixed with the rotating rod 71; the rotating rod 73 is rotatably set on the grinding plate 1 and is located above the worm 72; the turbine 74 is set on the rotating rod 73 and is coaxially fixed with the rotating rod 73, and the turbine 74 is meshed with the worm 72, and the rotating scraping plate 62 is coaxially fixed with the rotating rod 73.

[0034] When it is necessary to grind the concrete, first, when the roller 61 rotates under the movement of the grinding plate 1, the rotating rod 71 coaxially fixed with the roller 61 can be driven to rotate, and when the rotating rod 71 rotates, it can drive several worm gears 72 coaxially fixed therewith to rotate synchronously, and when the worm gear 72 rotates, the meshing turbine 74 can be rotated along the coaxially fixed rotating rod 73, and since the rotating scraper plate 62 is coaxially fixed with the rotating rod 73, when the turbine 74 rotates, the coaxially fixed rotating scraper plate 62 can be rotated, thereby realizing the rotational scraping and garbage removal of the concrete, improving the grinding effect of the grinding plate 1, and reducing the user's labor time in disguise.

[0035] See also Figures 1 - 6 As shown, the interlocking contact cutting mechanism 8 includes a travel groove 81, a sliding block 82 and a cutting knife 83; the travel groove 81 is opened on the handle 2 and has a pair; the sliding block 82 is slidably set in the travel groove 81 and has a pair; the cutting knife 83 is rotatably set on the sliding block 82 and is located above the coating rotating roller 3, and a storage block 831 is rotatably set on the handle 2 for storing the cutting knife 83.

[0036] When the grinding flat plate 1 moves, it can drive the film covering rotating roller 3 and the second rotating roller 5 to perform the film covering action on the ground concrete. When it is necessary to cut the film covering after covering the film covering rotating roller 3, first open the receiving block 831, and then open the cutting knife 83 at an inclined angle. During this process, the cutting knife 83 and the sliding block 82 can be driven to slide along the stroke groove 81 opened on the handle 2 until the cutting knife 83 contacts the film covering rotating roller 3. Then, after the cutting knife 83 and the sliding block 82 slide along the stroke groove 81, the film covering rotating roller 3 can be cut without manual cutting by the user, improving the work efficiency and reducing the work fatigue.

[0037] See Figures 7 - 9 As shown, the linkage contact cutting mechanism 8 further includes a first connecting rod 84, a limiting groove 85, a stroke block 851, a pressure-bearing roller 86 and a second connecting rod 87; the first connecting rod 84 is rotatably arranged on the sliding block 82; the limiting groove 85 is opened on the grinding flat plate 1 and has a pair; the stroke block 851 is slidably arranged on the limiting groove 85 and has a pair, and the first connecting rod 84 is rotatably connected with the stroke block 851; the pressure-bearing roller 86 is rotatably arranged on the grinding flat plate 1 and is located below the film covering rotating roller 3; the second connecting rod 87 is rotatably arranged on the stroke block 851 and the pressure-bearing roller 86.

[0038] When the cutting knife 83 and the sliding block 82 slide down vertically along the stroke groove 81, during this process, the first connecting rod 84 rotatably arranged on the sliding block 82 can be driven to push the stroke block 851 to slide. During this process, the stroke block 851 can be driven to slide horizontally to the right in the limiting groove 85 opened on the grinding flat plate 1. At this time, the sliding stroke block 851 can drive the pressure-bearing roller 86 rotatably connected through the second connecting rod 87 to move upward at an inclined angle until the pressure-bearing roller 86 is located below the film covering rotating roller 3 and close to the upper part of the cutting knife 83. When the cutting knife 83 cuts the film covering rotating roller 3, the pressure-bearing roller 86 can be driven to approach relatively, so that when the cutting knife 83 cuts, the contact support of the pressure-bearing roller 86 on the film covering rotating roller 3 can prevent the film covering workpiece from generating unnecessary tension due to the lack of support force during cutting, resulting in problems such as uneven cutting lines and rough edges of the film covering workpiece.

[0039] See Figures 5 - 7As shown, the concrete surface film covering device with a smoothing function further includes a disassembly and installation mechanism 9 for quickly installing the film covering rotating roller 3 onto the installation block 4; the disassembly and installation mechanism 9 includes a rotating block 91, a sliding rod 92, and a return spring 93; the rotating block 91 is rotatably arranged on the installation block 4; the sliding rod 92 is slidably arranged on the rotating block 91 in the horizontal linear direction; the return spring 93 is arranged on the sliding rod 92, and both ends of the return spring 93 are fixed to the sliding rod 92 and the end of the installation block 4 respectively.

[0040] When it is necessary to quickly disassemble the film covering rotating roller 3, first pull the sliding rod 92 to the side away from the film covering rotating roller 3 until the sliding rod 92 disengages from the outside of the film covering rotating roller 3. At this time, the return spring 93 is compressed. At this time, without the clamping of the sliding rod 92 on the film covering rotating roller 3, then tilt the rotating block 91. At this time, the efficiency of disassembling the film covering rotating roller 3 can be achieved, and the actions of quickly installing and disassembling the film covering rotating roller 3 can be realized.

[0041] See Figure 10 As shown, the disassembly and installation mechanism 9 further includes an installation groove 94 and a locking rod 95; the installation groove 94 is arranged on the sliding rod 92, and the installation groove 94 is used to insert the film covering rotating roller 3 into the installation groove 94; the locking rod 95 is threadedly arranged on the installation plate, the locking rod 95 is threadedly connected to the rotating block 91, and the locking rod 95 is used to lock the rotating rotating block 91 in a threaded connection.

[0042] When it is necessary to fix the installed film covering rotating roller 3 after installation, first tilt and swing the rotating block 91. At this time, place the film covering rotating roller 3 on the installation groove 94 arranged on the sliding rod 92 until the film covering rotating roller 3 is installed and horizontally clamped on the sliding rod 92. Then release the sliding rod 92. At this time, the compressed return spring 93 is released. At this time, the sliding rod 92 and the installation groove 94 can press the film covering rotating roller 3 against the installation block 4. Then thread the locking rod 95 onto the rotating block 91. At this time, the inclination of the rotating block 91 can be fixed, achieving the quick installation and fixation of the film covering rotating roller 3 and preventing the free rotation of the film covering rotating roller 3 and the rotating block 91.

Therefore, the protection scope of the present invention should be subject to the appended claims.
