Description

Technical Field

[0001] The utility model belongs to the technical field of floor processing equipment, and in particular relates to a floor surface grinding device. Background Art

[0002] The floor surface grinding device is a mechanical device specially used for grinding and polishing various floor surfaces. It can effectively remove old coatings, scratches, stains and uneven parts on the floor surface, and restore the gloss and smoothness of the floor. It is widely used in the maintenance and renovation of floors of different materials such as wooden floors, tiles, marble, concrete, etc.

[0003] For example, the Chinese utility model patent with the announcement number CN220718897U discloses a plate spray pretreatment grinding device. The device sets a cross-shaped moving component on the grinding table, so that the bottom grinding disc can be moved and adjusted to each corner, thereby achieving all-round grinding treatment of the plate surface, thereby improving the overall grinding effect.

[0004] However, in actual use, the grinding disc has a fixed size, so its contact area with the floor surface is relatively limited. Although the grinding disc can be adjusted to move in all directions, it is relatively troublesome to frequently move the grinding disc back and forth and left and right when processing a large area of floor, thereby reducing the grinding efficiency of the floor.

[0005] In summary, there is a need for a floor surface polishing device that can adjust the polishing area. Utility Model Content

[0006] The purpose of this utility model is to provide a floor surface polishing device. The device polishes the floor by rotating a polishing disc driven by a motor, and simultaneously rotates two sets of discs using a gear assembly, thereby increasing the polishing area, reducing the number of times the position of the polishing disc needs to be adjusted, and thus improving the floor polishing efficiency.

[0007] The technical solution adopted by the present invention to solve the above problems is: a floor surface grinding device, comprising:

[0008] A base, a grinding table is provided on the top of the base, a bracket is fixedly connected to the base, an electric push rod is fixedly connected to the top of the bracket, the telescopic end of the electric push rod is fixedly connected to the motor, and the rotor end of the motor is fixedly connected to the grinding disc through a connecting shaft;

[0009] An extended grinding assembly includes a frame body fixedly connected to the telescopic end of the electric push rod through a connecting frame, and a disc is rotatably connected in the frame body, and the disc is provided in two groups;

[0010] The gear assembly is arranged between the two groups of discs and is used to drive the two groups of discs to rotate simultaneously.

[0011] A further preferred technical solution is that: the gear assembly includes a first gear coaxially arranged below the disc, a second gear fixedly sleeved on the connecting shaft and meshed with the two groups of first gears at the same time, a vertical rod fixedly connected to the top of the disc near the edge, a bar frame movably sleeved on the vertical rod, a first connecting rod fixedly connected to the side of the bar frame and the first connecting rod is slidably connected to the frame body, a first polishing plate fixedly connected to the first connecting rod via a connecting piece, a second connecting rod slidably connected to the frame body, one end of the second connecting rod fixedly connected to the second polishing plate via a connecting piece, and a connecting rod hinged to the second connecting rod and the bar frame via a hinge.

[0012] A further preferred technical solution is that: a sliding rod is fixedly connected to the top of the base and the sliding rod is slidably connected to the polishing table, and an electric telescopic rod is fixedly connected to the top of the base and the telescopic end of the electric telescopic rod is fixedly connected to the polishing table.

[0013] A further preferred technical solution is that: a fixed plate is fixedly connected to the top of the grinding table, a clamping plate is provided on the top of the grinding table, a screw rod is rotatably connected to the side of the clamping plate, and the screw rod and the fixed plate are threadedly connected.

[0014] A further preferred technical solution is that: a guide rod is fixedly connected to the side of the clamping plate, and the guide rod is slidably connected to the fixed plate.

[0015] A further preferred technical solution is that: an anti-slip pad is provided on the splint.

[0016] A further preferred technical solution is that the bottoms of the grinding disc, the first grinding plate and the second grinding plate are all on the same horizontal line.

[0017] A further preferred technical solution is that the top of the vertical rod is fixedly connected to a limiting plate.

[0018] A further preferred technical solution is that the diameters of the two groups of discs are equal.

[0019] A further preferred technical solution is that the length of the second grinding plate is greater than the length of the first grinding plate.

[0020] In summary, the present invention has the following advantages:

[0021] 1. The present invention polishes the floor by rotating the grinding disc driven by a motor. The meshing action between the second gear and the two sets of first gears enables the two sets of discs to rotate simultaneously. The rotation of the discs drives the vertical rod to perform circular motion. The movable cooperation between the vertical rod and the bar frame, and the sliding cooperation between the first connecting rod and the frame body, enables the first grinding plate to move back and forth, thereby increasing the grinding range on both sides of the grinding disc. The increase in the grinding area reduces the number of times the position of the grinding disc needs to be adjusted, thereby improving the grinding efficiency of the floor.

[0022] 2. While driving the two groups of first sanding plates to move back and forth left and right, the utility model utilizes the hinged effect between the bar frame and the second connecting rod and the connecting rod, and the sliding cooperation between the second connecting rod and the frame body, so that the second sanding plates can be driven to move back and forth, thereby increasing the sanding range of the sanding discs, further reducing the number of times the position of the sanding discs needs to be adjusted, and improving the sanding efficiency of the floor.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0029] Example:

[0030] Please combine Figure 1-3, a floor surface polishing device of this embodiment includes:

[0031] A base 1 is provided with a polishing table 2 on the top of the base 1, a bracket is fixedly connected to the base 1, an electric push rod 3 is fixedly connected to the top of the bracket, the telescopic end of the electric push rod 3 is fixedly connected to the motor, and the rotor end of the motor is fixedly connected to the polishing disc 4 through a connecting shaft, a sliding rod 5 is symmetrically fixedly connected to the top of the base 1, and the sliding rod 5 is slidably connected to the polishing table 2, an electric telescopic rod 6 is symmetrically fixedly connected to one side of the top of the base 1, and the telescopic end of the electric telescopic rod 6 is fixedly connected to the polishing table 2, which is convenient for adjusting the left and right position of the polishing table 2, thereby realizing the change of the polishing position of the floor surface;

[0032] The extended grinding assembly includes a frame body 101 fixedly connected to the telescopic end of the electric push rod 3 through a connecting frame, and the inner side of the frame body 101 is symmetrically connected to the disc 102. The diameters of the two groups of discs 102 are consistent. The lower part of the disc 102 is coaxially fixedly connected to the first gear 103. The external fixed sleeve of the connecting shaft is provided with a second gear 104 and is simultaneously meshed with the two groups of first gears 103. The top of the disc 102 is fixedly connected to the position near the edge. The external movable sleeve of the vertical rod 105 is provided with a strip frame 106. One side of the strip frame 106 is fixedly connected to the first connecting rod 107 and the first connecting rod 107 is slidably connected to the frame body 101. The end of the first connecting rod 107 is fixedly connected to the first grinding plate 108 through a connecting piece. 01 is symmetrically and slidingly connected with a second connecting rod 109 on both sides, and one end of the second connecting rod 109 is fixedly connected to a second grinding plate 110 through a connecting piece. The length of the second grinding plate 110 is greater than the length of the first grinding plate 108. The other end of the second connecting rod 109 is hinged to the bar frame 106 with a connecting rod 111 through a hinge. The bottoms of the grinding disc 4, the first grinding plate 108 and the second grinding plate 110 are all on the same horizontal line, which is convenient for the grinding disc 4, the first grinding plate 108 and the second grinding plate 110 to grind the floor at the same time. The top of the vertical rod 105 is fixedly connected to a limiting plate, which can prevent the vertical rod 105 from detaching from the bar frame 106. The two groups of vertical rods 105 are arranged in a mirror-symmetrical manner, which is convenient for driving the two groups of first grinding plates 108 to move outward or inward at the same time.

[0033] The implementation principle of a floor surface grinding device in the embodiment of the present application is as follows: first, the floor is placed on the grinding table 2, and then the motor and the electric push rod 3 are started. The motor will drive the grinding disc 4 to rotate, and the electric push rod 3 will push the rotating grinding disc 4 to approach the floor surface for grinding. At the same time, the rotation of the grinding disc 4 will drive the second gear 104 to rotate. The meshing action between the second gear 104 and the two groups of first gears 103 can drive the two groups of discs 102 to rotate at the same time. The rotation of the disc 102 drives the vertical rod 105 to perform a circular motion. The movable cooperation between the vertical rod 105 and the bar frame 106 and the sliding cooperation between the first connecting rod 107 and the frame body 101 can drive the first grinding plate 108 to move back and forth left and right. , thereby increasing the grinding range on both sides of the grinding disc 4, and while driving the two groups of first grinding plates 108 to move back and forth left and right, the bar frame 106 and the hinged effect between the second connecting rod 109 and the connecting rod 111, the sliding cooperation between the second connecting rod 109 and the frame body 101, can drive the second grinding plate 110 to move back and forth, thereby increasing the grinding range of the front and back of the grinding disc 4. Due to the increase in the grinding area, the number of position adjustments of the grinding disc 4 is reduced, thereby improving the grinding efficiency of the floor. Then, the electric telescopic rod 6 is started to push the grinding table 2 to move on the base 1, so that the grinding position of the floor can be changed. The operation is simple, convenient and practical. Finally, the floor can be removed after grinding.

[0034] In addition, further improvements are: the top of the polishing table 2 is symmetrically fixedly connected with a fixed plate, and the top of the polishing table 2 is symmetrically provided with a plywood 7, one side of the plywood 7 is rotatably connected with a screw rod 8 and the screw rod 8 is threadedly connected to the fixed plate, and the plywood 7 is driven closer to the floor by rotating the screw rod 8, so that the floor can be fixed, and one side of the plywood 7 is symmetrically fixedly connected with a guide rod and the guide rod is slidably connected to the fixed plate, which can play a certain guiding role in the horizontal movement of the plywood 7, and the opposing surfaces of the two sets of plywood 7 are provided with anti-slip pads, which can increase the friction between the plywood 7 and the floor, and effectively improve the clamping and fixing effect of the floor.
