Description

Technical Field

[0001] This utility model relates to the field of cement board manufacturing technology, specifically to a high-efficiency processing device for uniformly flattening composite cement boards. Background Technology

[0002] In the production of composite cement boards, the leveling and uniformity of the mortar during the molding stage directly determines the quality of the boards. Current technology relies on manual labor using scrapers or simple tools to level the mortar, which is not only labor-intensive but also makes it difficult to ensure uniform dispersion of aggregates within the mortar, easily leading to localized density differences, resulting in board cracking and insufficient strength.

[0003] Some automated equipment has a fixed mixing structure that cannot be adapted to the mold depth. For shallow molds, it is easy to stir up mortar and cause waste, while for deep molds, the mixing is insufficient. The fixed angle of the mixing teeth makes it difficult to adapt to mortars with different fluidity, such as high viscosity mortar, which is prone to clumping, and low viscosity mortar, which is prone to separation. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency processing device for uniformly flattening composite cement boards in order to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a high-efficiency processing device for uniformly spreading composite cement board, including a fixed frame, a rotating component, and a drum rotatably connected to the fixed frame via the rotating component. The drum is equipped with a stirring component for stirring mortar as the drum rotates.

[0007] The stirring assembly includes fixed teeth and movable teeth rotatably connected to the fixed teeth. By rotating the movable teeth to adjust the overlapping part of the movable teeth and the fixed teeth, the length of the stirring assembly protruding from the surface of the drum can be changed.

[0008] Preferably, a handle is fixedly installed on the fixed frame.

[0009] Preferably, a threaded sleeve is fixedly connected to the fixed frame, and the handle is threadedly connected to the threaded sleeve.

[0010] Preferably, the rotating assembly includes a rotating shaft rotatably connected to a fixed frame, a roller fixedly connected to the rotating shaft, a motor fixedly connected to the fixed frame, and bevel gears fixedly connected to both the motor output shaft and the rotating shaft, with the two bevel gears meshing.

[0011] Preferably, a gear cover is fixedly connected to the fixed frame to cover the two bevel gears, and the bevel gears do not contact the gear cover.

[0012] Preferably, retaining rings are fixedly connected to both ends of the roller.

[0013] Preferably, the stirring assembly includes several fixed teeth that are equidistantly fixed to the drum in a linear array, and a rotating shaft is rotatably connected between the fixed teeth. Several movable teeth are fixedly connected to the rotating shaft, and the movable teeth can rotate to a position flush with the end of the fixed teeth away from the drum.

[0014] Preferably, the stirring assembly further includes a fixing component for fixing the second rotating shaft, and the fixing component is installed on any one of the ends of the fixed tooth linear array.

[0015] Preferably, the fixing component includes a connecting plate, a guide post is slidably connected to the connecting plate, the guide post is fixedly connected to the corresponding fixing tooth, a polygonal prism is fixedly connected to the connecting plate, a polygonal groove is opened at one end of the rotating shaft, and the polygonal prism and the polygonal groove are clearance-fitted, and a nut is threadedly connected to the guide post for fixing the connecting plate.

[0016] The beneficial effects are:

[0017] The mixing assembly, consisting of fixed and movable teeth, is driven to rotate by a roller. The fixed and movable teeth penetrate deep into the mortar to create a three-dimensional mixing effect, effectively breaking up aggregate agglomerates and eliminating internal air bubbles. The roller moves horizontally on the mold, which can improve the efficiency and quality of mortar spreading and solve the problem of uneven density caused by traditional manual spreading. At the same time, the movable teeth can rotate to adjust the overlap with the fixed teeth, flexibly changing the length of the mixing assembly protruding from the roller surface to adapt to molds of different depths. This ensures that there is no material spillage in shallow molds and thorough mixing in deep molds, significantly improving the homogeneity of the mortar. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] See Figures 1-5 As shown, this utility model provides a high-efficiency processing device for uniformly flattening composite cement boards, including a fixed frame 1, a rotating component 4, and a roller 5 rotatably connected to the fixed frame 1 via the rotating component 4. A mixing component 6 is provided on the roller 5 for mixing mortar as the roller 5 rotates.

[0028] The stirring assembly 6 includes a fixed tooth 602 and a movable tooth 603 rotatably connected to the fixed tooth 602. By rotating the movable tooth 603 to adjust the overlapping part of the movable tooth 603 and the fixed tooth 602, the length of the stirring assembly 6 protruding from the surface of the drum 5 can be changed.

[0029] As an optional implementation method, Figure 1 and Figure 2 A handle 2 is fixedly installed on the fixed frame 1. A threaded sleeve 3 is fixedly connected to the fixed frame 1, and the handle 2 is threadedly connected to the threaded sleeve 3.

[0030] In this embodiment, the device can be stably operated by holding the handle 2 with both hands, and the handle 2 can be separated from the fixed frame 1, making the device easy to carry.

[0031] As an optional implementation method, Figure 1 and Figure 3The rotating assembly 4 includes a rotating shaft 402 rotatably connected to the fixed frame 1, a roller 5 fixedly connected to the rotating shaft 402, a motor 401 fixedly connected to the fixed frame 1, and bevel gears 405 fixedly connected to both the output shaft of the motor 401 and the rotating shaft 402, with the two bevel gears 405 meshing. A gear cover 404 is fixedly connected to the fixed frame 1 to cover the two bevel gears 405, and the bevel gears 405 do not contact the gear cover 404.

[0032] A battery is installed on the fixed frame 1 to supply power to the motor 401.

[0033] In this embodiment, the motor 401, in cooperation with the two bevel gears 405, can drive the rotating shaft 402 and the roller 5 to rotate. The bevel gears 405 are protected by the gear cover 404 to prevent cement from interfering with the meshing of the two bevel gears 405.

[0034] As an optional implementation method, Figure 3 , Figure 4 as well as Figure 5 Both ends of the drum 5 are fixedly connected with retaining rings 403. The stirring assembly 6 includes several fixed teeth 602 that are equidistantly fixed on the drum 5 in a linear array, and a rotating shaft 601 is rotatably connected between the fixed teeth 602. Several movable teeth 603 are fixedly connected to the rotating shaft 601, and the movable teeth 603 can rotate to a position flush with the end of the fixed teeth 602 away from the drum 5. The stirring assembly 6 also includes a fixing assembly 7 for fixing the rotating shaft 601. The fixing assembly 7 is installed on any one of the ends of the linear array of fixed teeth 602. The fixing assembly 7 includes a connecting plate 701, a guide post 703 that is slidably connected to the connecting plate 701, the guide post 703 being fixedly connected to the corresponding fixed tooth 602, a polygonal prism 702 fixedly connected to the connecting plate 701, a polygonal groove opened at one end of the rotating shaft 601, and the polygonal prism 702 and the polygonal groove being clearance-fitted. A nut 704 is threadedly connected to the guide post 703 for fixing the connecting plate 701.

[0035] In this embodiment, the roller 5 drives the mixing assembly 6 to rotate, and the mixing assembly 6 can mix the cement filled in the mold to make the cement uniform inside.

[0036] Among them, the fixed tooth 602 and the movable tooth 603 are the core components of the mixing assembly 6. The fixed tooth 602 and the movable tooth 603 are used to extend into the concrete and mix the concrete.

[0037] When the movable tooth 603 is fully extended, it fully extends into the concrete, increasing the depth of concrete mixing. This is the maximum mixing amplitude of the device. By rotating the movable tooth 603 to coincide with the fixed tooth 602, the mixing amplitude of the concrete can be reduced accordingly.

[0038] By making the above adjustments to the mixing component 6, the mixing amplitude of the concrete can be adjusted on the one hand, and the molds of different depths can be adapted on the other hand.

[0039] After each adjustment of the angle of the movable tooth 603, the rotating shaft 601 is fixed by the fixing component 7, thereby fixing the angle of the movable tooth 603.

[0040] Specifically, the principle of fixing component 7 is as follows: the polygonal prism 702 is inserted into the polygonal groove of the rotating shaft 601, the connecting plate 701 is slidably set on the guide post 703, and the connecting plate 701 is pushed by rotating the nut 704 so that the connecting plate 701 is close to the fixing tooth 602 until the polygonal prism 702 is fully inserted into the polygonal groove, thus completing the fixing of the connecting plate 701.

[0041] It should be noted that the rotating component 4 drives the drum 5 to rotate at a low speed to prevent the mixing component 6 from throwing the concrete out of the mold due to excessive speed.

[0042] Working principle:

[0043] Taking a rectangular mold as an example, the roller 5 is placed on the mold. The length of the roller 5 is greater than the width of the mold. The mixing component 6 corresponds to the inside of the mold. The roller 5 is moved along the length of the mold. During this process, the concrete is mixed by the mixing component 6.

[0044] After mixing, the roller 5 is rotated by the rotating component 4, and the mixing component 6 is rotated above the concrete. By moving the roller 5 across the mold, the concrete surface can be smoothed.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
