Description

Technical Field

[0001] This utility model relates to the field of concrete slab processing, and in particular to a concrete slab edge grinding machine. Background Technology

[0002] Concrete slabs are precast reinforced concrete slab components. In building construction, they mainly include wall panels, floor slabs, and roof panels; these three types of slabs are sometimes interchangeable. Concrete slabs are mainly divided into two categories: reinforced concrete and prestressed concrete. Some also use other reinforcement materials, such as wire mesh, steel fiber, or other fibers. To improve the later splicing strength and service performance, the concrete needs to be edge-ground after molding.

[0003] For example, patent document CN222386594U discloses a grinding device for ultra-high bonding strength concrete slabs. The concrete slab is placed on a placement plate, and a clamping plate fixes the concrete slab. A grinding motor drives a grinding wheel to rotate and grind the edges of the concrete slab. The dust generated during the grinding process can seep down through a filter plate into a dust collection trough for easy centralized treatment. However, because the dust generated during grinding is scattered everywhere, it cannot completely seep down through the filter plate into the dust collection trough, resulting in a mediocre cleaning effect. A layer of dust also remains on the surface of the ground concrete, requiring further cleaning, which increases the operation steps and makes the overall effect generally poor. Utility Model Content

[0004] The purpose of this invention is to provide a grinding machine for concrete slabs in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8 As shown, a concrete slab edge grinding machine includes a base 1, a worktable 101 fixed on the top of the base 1, a turntable 102 rotatably mounted on the top of the worktable 101, a rotary motor built into the turntable 102, the output shaft of the rotary motor being fixedly connected to the turntable 102, the slab being placed on the turntable 102, and the rotary motor driving the turntable 102 to rotate, thereby causing the slab to rotate, clamping mechanisms 2 are provided at both ends of the top of the worktable 101, the clamping mechanisms 2 are used to keep the slab fixed during the edge grinding process, a U-shaped frame 3 is slidably connected to the top of the base 1, an electric telescopic cylinder 103 is fixedly connected to the rear side of the worktable 101, the output end of the electric telescopic cylinder 103 is fixedly connected to the U-shaped frame 3, the electric telescopic cylinder 103 is used to control the forward and backward movement of the U-shaped frame 3, the U-shaped frame 3 is located on the rear side of the worktable 101, a translation mechanism 4 is provided on the U-shaped frame 3, a protective box 5 is provided on the translation mechanism 4, the translation mechanism 4 is used to drive the protective box 5 to translate left and right.

[0031] The protective box 5 has an opening at its front end, and brush bristles 501 are fixed to the inner wall of the opening. A grinding shaft 6 and two cleaning shafts 7 are connected to the rear wall of the protective box 5 via bearings. The cleaning shafts 7 are located on both sides of the grinding shaft 6. A grinding disc 601 is fixed to the front end of the grinding shaft 6, and a brush disc 701 is installed at the front end of the cleaning shafts 7. A power mechanism 9 for driving the grinding shaft 6 and cleaning shafts 7 to rotate is located at the rear of the protective box 5. During edge grinding, the opening of the protective box 5 is aligned with the rear end of the board material. At this time, the board material blocks the opening of the protective box 5, thus allowing the edge grinding to proceed smoothly. The dust generated during the process will not escape from the opening of the protective box 5. The brush bristles 501 prevent the protective box 5 from directly contacting the board, thus preventing wear and tear on the board during the movement of the protective box 5. At the same time, the brush bristles 501 can also prevent dust from escaping. The edge of the board is ground by the grinding disc 601, and the dust on the back side of the board is cleaned by the brush disc 701. The rear end of the base 1 is equipped with a dust collection mechanism 8 that is connected to the protective box 5. The dust generated during edge grinding is collected inside the protective box 5 and is extracted and collected by the dust collection mechanism 8.

[0032] A spline sleeve 702 is connected to the rear side of the brush disc 701 by screws. The spline sleeve 702 is connected to the front end of the cleaning shaft 7 by splines, so that the brush disc 701 can move back and forth while the cleaning shaft 7 drives the brush disc 701 to rotate. A spring 703 is fixedly connected to the rear side of the brush disc 701. A limit plate 704 is fixedly connected to the rear end of the spring 703. The limit plate 704 is fixedly connected to the cleaning shaft 7. A first convex ball 705 is welded to the rear side of the brush disc 701. A pressing component is sleeved around the spring 703. The pressing component is used to press the first convex ball 705 to move forward.

[0033] The extrusion assembly includes a support plate 706, which is connected to the inner wall of the protective box 5 by screws. A fixing ring 707 is connected to the support plate 706 by screws. The fixing ring 707 is located around the spring 703. A second convex ball 708 is fixedly connected to the front side of the fixing ring 707. The second convex ball 708 can abut against the first convex ball 705. When the cleaning shaft 7 drives the brush disc 701 to rotate, the first convex ball 705 and the second convex ball 708 will intermittently abut against each other. Upon contact with the brush plate 701, the brush plate 701 is pressed forward, the spring 703 is stretched, and the first convex ball 705 separates from the second convex ball 708. The spring 703 then causes the brush plate 701 to rebound rapidly, causing the first convex ball 705 to move backward and collide with the fixing ring 707. This causes the brush plate 701 to vibrate, which shakes off the dust and debris on the brush plate 701. This prevents the dust and debris remaining on the brush plate 701 from being adsorbed onto the board again, keeping the brush plate 701 clean and ensuring the cleaning effect of dust and debris.

[0034] The power mechanism 9 includes a motor frame 901, which is connected to the rear of the protective box 5 by screws. A power motor 902 is connected to the motor frame 901 by bolts. The output end of the power motor 902 is connected to a pulley assembly 903. The grinding shaft 6 and the two sweeping shafts 7 are connected through the pulley assembly 903. The power motor 902 drives the grinding shaft 6 and the two sweeping shafts 7 to rotate simultaneously through the pulley assembly 903.

[0035] The translation mechanism 4 includes a translation motor 401, which is bolted to one side of the U-shaped frame 3. The output shaft of the translation motor 401 is fixedly connected to a lead screw 402, which is connected to the U-shaped frame 3 through a bearing. A slider 403 is threaded onto the lead screw 402, which is slidably connected to the U-shaped frame 3. The protective box 5 is fixedly connected to the bottom of the slider 403. The translation motor 401 drives the lead screw 402 to rotate, causing the slider 403 to move the protective box 5 left and right, thereby moving the grinding disc 601 along the rear side of the plate.

[0036] The dust collection mechanism 8 includes a dust collection box 801, which is fixedly connected to the top of the base 1. An air pump 802 is fixedly connected to the dust collection box 801, and a hose 803 is connected to the dust collection box 801. The other end of the hose 803 is connected to the bottom of the protective box 5.

[0037] The clamping mechanism 2 includes a support 201, which is fixedly connected to the top of the workbench 101. A hydraulic cylinder 202 is fixedly connected to the support 201, and a clamping plate 203 is fixedly connected to the output end of the hydraulic cylinder 202.

[0038] Working principle: In use, the concrete slab is placed on the turntable 102. The hydraulic cylinder 202 drives the clamping plate 203 to move, and the clamping plates 203 on both sides clamp and fix the slab. The electric telescopic cylinder 103 drives the U-shaped frame 3 to move forward, so that the protective box 5 moves forward and aligns the opening of the protective box 5 with the rear end of the slab. At this time, the slab blocks the opening of the protective box 5, preventing dust generated during edge grinding from escaping from the opening. The power motor 902 drives the grinding shaft 6 and the two cleaning shafts 7 to rotate simultaneously through the pulley assembly 903. The grinding disc 601 rotates to grind the edge of the slab, and the brush disc 701 rotates to clean the dust adsorbed on the rear side of the slab. When the brush disc 701 rotates, the first convex ball 705 and the second convex ball 708 will intermittently collide. When the first convex ball 705 and the second convex ball 708 collide, the brush disc 701 is squeezed forward and springs back. When the spring 703 is stretched, the first convex ball 705 separates from the second convex ball 708. The spring 703 then drives the brush disc 701 to rebound quickly, causing the first convex ball 705 to move backward and collide with the fixing ring 707. This causes the brush disc 701 to vibrate, which can shake off the dust and debris on the brush disc 701. This prevents the dust and debris remaining on the brush disc 701 from being adsorbed onto the board again, keeping the brush disc 701 clean and ensuring the cleaning effect. The air pump 802 is started, and the dust and debris in the protective box 5 are sucked into the dust collection box 801 through the hose 803. After the grinding of one side is completed, the clamping plate 203 loosens the board, and then the turntable 102 rotates so that the other side of the board is on the rear side. The clamping plate 203 then fixes the board again, and then the edge grinding operation is performed again. This process is repeated until all four sides of the board are ground.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
