Detailed implementation

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0031] As Figure 1-7 shown, the present invention provides a surface grinding device for modular floor slabs, including a frame mechanism 100, a grinding mechanism 200 and a dust suction mechanism 300;

[0032] The frame mechanism includes a grinding table 101 and a clamping assembly 102 located below the grinding table 101. A gantry 103 is fixedly arranged on the top of the grinding table 101;

[0033] The dust suction mechanism 300 includes a dust suction hood 301 and a cylinder 302. The cylinder 302 is fixedly installed on the gantry 103 and its movable end is connected to the dust suction hood 301;

[0034] The grinding mechanism 200 includes a moving assembly I 201, a moving assembly II 202 and a grinding machine 203. The moving assembly I 201 and the moving assembly II 202 drive the grinding machine 203 to move to realize the grinding of the surface of the modular floor slab.

[0035] In this embodiment, the moving component I 201 includes a motor I 2011 and a lead screw 2012. The motor I 2011 is fixedly installed on one side of the dust suction hood 301. The lead screw 2012 is rotatably arranged inside the dust suction hood 301 and one end of it is connected to the output shaft of the motor I 2011. A moving block 2013 is threadedly connected to the lead screw 2012. The motor I 2011 drives the lead screw 2012 to move the moving block 2013, realizing the movement of the moving component II 202 in the left - right direction.

[0036] In this embodiment, the moving component II 202 includes a connecting platform 2021. A bearing seat 2022 is slidably arranged inside the connecting platform 2021. The grinding machine 203 is installed inside the bearing seat 2022. A motor II 2023 is fixedly installed on the top of the bearing seat 2022. A tooth groove 2024 is formed inside the connecting platform 2021. A gear 2025 meshing with the tooth groove 2024 is fixedly sleeved on the output shaft of the motor II 2023. The motor II 2023 rotates the gear 2025 and cooperates with the tooth groove 2024 to make the bearing seat 2022 drive the grinding machine 203 to move.

[0037] In this embodiment, support plates 2014 are fixedly connected to both the left and right sides of the moving block 2013. The ends of the two support plates 2014 far from the moving block 2013 are fixedly connected to the left and right sides of the connecting platform 2021.

[0038] In this embodiment, U - shaped seats 2026 are fixedly connected to both the front and rear sides of the connecting platform 2021. The two U - shaped seats 2026 are clamped on the dust suction hood 301 and move along the length direction of the dust suction hood 301. The cooperation between the U - shaped seats 2026 and the dust suction hood 301 limits the movement of the connecting platform 2021, enabling the connecting platform 2021 to move stably in a straight line.

[0039] In this embodiment, a dust collection box 303 is fixedly connected below the grinding table 101. A number of dust suction fans 304 arranged at intervals are embedded and installed on the back of the dust collection box 303. A dust collection drawer 305 is inserted inside the dust collection box 303. A filter plate 306 is arranged on the side of the dust collection drawer 305 in contact with the dust suction fans 304. A dust suction pipe 307 is connected and installed between the dust collection box 303 and the dust suction hood 301. When the dust suction fans 304 are turned on to suck air, the dust generated by grinding is sucked into the dust collection box 303 through the dust suction pipe 307. Due to the setting of the filter plate 306, the dust is prevented from overflowing through the dust suction fans 304, and the dust is collected in the dust suction drawer.

[0040] In this embodiment, a support frame 104 located above the dust collection box 303 is fixedly connected below the grinding table 101. The clamping assembly 102 includes a motor III 1021 fixedly installed on the support frame 104. A turntable 1022 is installed on the output shaft of the motor III 1021. Two pins 1023 are fixedly connected to the top of the turntable 1022. Pull rods 1024 are respectively hingedly installed on the two pins 1023. One end of the pull rod 1024 away from the pin 1023 is hingedly installed with a connecting plate 1025. A number of spaced through slots 105 are formed on the grinding table 101. A vertical rod 1026 connected to the connecting plate 1025 is slidably arranged in the through slot 105. The top end of the vertical rod 1026 is fixedly connected with a clamping plate 1027. The motor III 1021 rotates the turntable 1022, pulls the pull rod 1024 through the pin 1023, and the pull rod 1024 pulls the connecting plate 1025 to make the vertical rod 1026 slide in the chute, and the vertical rod 1026 drives the clamping plate 1027 to move to clamp the floor slab, so as to perform grinding smoothly.

[0041] In this embodiment, two sets of moving assemblies II 202 are provided, and the stroke of each moving assembly II 202 is greater than half of the length of the dust suction hood 301. The strokes of the two moving assemblies II 202 can fully cover the length of the dust suction hood 301, ensuring the comprehensiveness of the grinding efficiency.

[0042] In this application, it can cooperate with the controller and the trigger switch to control the forward and reverse rotations of the motor I 2011 and the motor II 2023 to realize commutation, which will not be specifically described here.

[0043] Usage method and working principle of this device:

[0044] When using this device, first place the floor slab to be ground on the grinding table 101. The motor III 1021 rotates the turntable 1022 and pulls the pull rod 1024 through the pin 1023. The pull rod 1024 pulls the connecting plate 1025 to make the vertical rod 1026 slide in the chute, and the vertical rod 1026 drives the clamping plate 1027 to move to clamp the floor slab, so that the floor slab is stably located on the grinding table 101.

[0045] Subsequently, the air cylinder 302 extends to push the dust suction hood 301 to move downward so that the grinding machine 203 contacts the surface of the floor slab. The motor I 2011 and the motor II 2023 are started simultaneously. The motor I 2011 drives the lead screw 2012 to move the moving block 2013. The moving block 2013 makes the connecting table 2021 move left and right through the support plate 2014. The motor II 2023 rotates the gear 2025 and cooperates with the tooth groove 2024 to make the bearing seat 2022 drive the grinding machine 203 to move back and forth. Since the grinding machine 203 moves left and right and back and forth, the grinding range is wide and the grinding force always remains consistent. While improving the grinding efficiency, it also helps to improve the uniformity of the grinding quality, thus ensuring the grinding quality.

[0046] And during the grinding process, the dust suction fan 304 keeps working to suck air. The dust generated by grinding is sucked into the dust collection box 303 through the dust suction pipe 307. Due to the setting of the filter plate 306, the dust is prevented from overflowing through the dust suction fan 304, and the dust is filtered and stays in the dust suction drawer for collection, avoiding the pollution of the on-site grinding construction environment caused by the dust generated by grinding and also avoiding harm to the health of construction workers.

[0047] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
