Description

Technical Field

[0001] The utility model relates to the field of napping machines, in particular to a napping machine with a uniform pulling force function. Background Art

[0002] During the construction process, when pouring concrete foundations, walls or floor slabs, a roughening board or a roughening machine is often used to roughen the concrete surface. The roughening board or the roughening machine will scrape horizontal and vertical grooves on the concrete surface, so that the concrete surface presents special textures. After such treatment, the textures on the concrete surface can increase the roughness of the concrete surface, make the concrete surface more compact, and enhance the bearing capacity of the concrete. In the prior art, a Chinese utility model type with a public document number of CN209425753U discloses a concrete component surface roughening machine, which converts the telescopic movement of the telescopic device into the swing of the rotating frame, has a simple structure and low maintenance cost;

[0003] However, when the concrete precast panels are roughened, debris is likely to appear on the surface of the precast panels after the roughening. The utility model does not have a corresponding device for cleaning the debris. In addition, when different concrete precast panels are roughened, the hardness and roughening depth of the precast panels are uncertain. This requires the roughening knife to be able to flexibly adjust the tension so as to facilitate pulling out suitable notches on various precast panels. However, in the comparative document, there is a lack of a structure for adjusting the tension, so improvement is needed. Utility Model Content

The output shaft of the stepper motor 11 is fixedly connected with one end of the screw 7, and the output shaft of the cylinder 3 pushes the workbench 2 to move upward, so as to flexibly adjust the height of the workbench 2, so that the roughening sheet 17 is convenient for carving a groove of suitable depth on the concrete precast board, and then by controlling the output torque of the stepper motor 11, the screw 7 is subjected to different rotational forces to rotate, so that the connecting frame 16 and the roughening sheet 17 are moved, and the output torque adjusted according to the actual hardness of the concrete precast board and the depth of the groove makes the connecting frame 16 and the roughening sheet 17 more evenly stressed and move more smoothly.

[0022] like Figure 1 and Figure 4As shown, a vent pipe 23 is movably installed at one side of the workbench 2, and the vent pipe 23 is movably installed in the connecting ring 21. A rotating rod 20 is fixedly connected to the bottom of the connecting ring 21. A support plate 18 is fixedly connected to one side of the workbench 2. The rotating rod 20 is movably installed with the support plate 18 through a damping bearing 19. A filling rubber ring 22 is fixedly connected in the connecting ring 21.

[0023] It should be noted that the utility model is a roughening machine with a uniform pulling force function. The concrete precast panel is placed on the workbench 2, and the cylinder 3 is started. The output shaft of the cylinder 3 pushes the workbench 2 to move upward, so that the height of the workbench 2 can be adjusted flexibly, so that the roughening sheet 17 can easily carve a groove of appropriate depth on the concrete precast panel.

By controlling the output torque of the stepper motor 11, the roughening sheet 17 is pushed by a suitable pulling force, and the roughening sheet 17 is smoother and less prone to blockage when scratching the surface of the concrete precast panel, so that the roughening sheet 17 is evenly stressed and moves smoothly. After the roughening sheet 17 finishes roughening, the workbench 2 is reset downward, and the concrete precast panel is pushed sideways. The blower 26 blows air into the vent pipe 23 through the hose 25, and the air flow is ejected downward through the jet port 24 of the vent pipe 23 to blow the concrete precast panel, making it more convenient to clean the debris on the concrete precast panel.
