[0015] The present invention provides a grinding device for anti-static epoxy floor construction. It has the following beneficial effects: When the height of the anti-static grinding equipment needs to be adjusted in this invention, first manually pull the protection rod to move away from the dust collection equipment. The anti-static grinding equipment has a high rotation speed and power. If the height of the anti-static grinding equipment is misadjusted, it may lead to improper operation.

[0016] In this invention, after the seal of the guide pipe is released, the quantitative epoxy resin cleaning agent inside the seal frame is sprayed onto the area to be ground through the guide pipe. Quantitative spraying can reduce the excessive residue of the epoxy resin cleaning agent on the ground. By using it quantitatively, it can ensure that there will be no excessive chemical residue on the ground after each cleaning. The movement of the placement rack drives the movement of the moving frame, and the movement of the moving frame cooperates with the epoxy resin cleaning agent to scrape off the epoxy resin residue in the area to be ground. After removing the epoxy resin residue, the grinding device can contact the ground more smoothly, reducing resistance and friction. If the epoxy resin residue is not removed, it will cause problems such as jamming during grinding and low efficiency. After scraping off the residue, the grinding process can be more stable.

[0017] In this invention, the larger particles at the bottom of the separation plate are pushed by the rotating rod to separate from the separation plate. The rotation of the rotating rod to push the particles away from the separation plate can prevent excessive accumulation of particles at the bottom of the separation plate, thereby improving the dust collection effect of the dust collection equipment. The vibration of the arc-shaped panel drives the vibration of the separation plate, and the vibration of the separation plate shakes off the larger particles at the bottom of the separation plate. The vibration of the separation plate can effectively shake off the larger particles from the bottom of the separation plate, preventing them from adhering to the separation plate due to static electricity or friction, and further ensuring the effective removal of larger particles.

[0025] During the operation of this embodiment: When it is necessary to adjust the height of the anti-static grinding device 7, first manually pull the protection rod 13 to move away from the dust suction device 4. When the protection rod 13 moves away from the dust suction device 4, it pulls the second spring. The second spring deforms and stores energy under the pull of the protection rod 13. At the same time, as the protection rod 13 moves away from the dust suction device 4, it disengages from the protection groove 12 and releases the limit on the limit rod 10. After the limit on the limit rod 10 is released, manually pull the limit disk 11 to move away from the adjustment tube 5. When the limit disk 11 moves away from the adjustment tube 5, it pulls the first spring. The first spring deforms and stores energy under the pull of the limit disk 11. At the same time, as the limit disk 11 moves away from the adjustment tube 5, it drives the limit rod 10 to move. The limit rod 10 moves away from the contact with the limit groove 71 and releases the limit on the adjustment rod 6. After the limit on the adjustment rod 6 is released, manually push the adjustment rod 6 to adjust the height. When the adjustment rod 6 adjusts the height, it drives the anti-static grinding device 7 to adjust the height. After the anti-static grinding device 7 is adjusted to the appropriate position, manually release the limit disk 11 so that the limit disk 11 moves towards the adjustment tube 5 under the elastic force of the first spring. As the limit disk 11 moves towards the adjustment tube 5, it drives the limit rod 10 to move. The limit rod 10 moves into contact with the limit groove 71 and restores the limit on the adjustment rod 6 and fixes the height of the dust suction device 4. After the height of the dust suction device 4 is fixed, start the anti-static grinding device 7 for operation. When the anti-static grinding device 7 is operating, manually push the U-shaped rod 3 to move horizontally. The horizontal movement of the U-shaped rod 3 cooperates with the roller 2 to drive the placement rack 1 to move. The movement of the placement rack 1 drives the adjustment rod 6 and the anti-static grinding device 7 to move. The movement of the anti-static grinding device 7 performs a grinding operation on the area to be ground.

The liquid spraying device includes a storage frame 141, a sealing frame 142, a sealing plate 143, an L-shaped plate 144, a sealing hole 145, a guiding tube 146 and a moving frame 148. The storage frame 141 is fixedly installed at the top left of the placement rack 1, the sealing frame 142 is fixedly installed at the bottom inner wall of the storage frame 141, the sealing plate 143 is slidably installed on the inner wall of the sealing frame 142, the L-shaped plate 144 is fixedly installed on the front side of the sealing plate 143, the sealing hole 145 is opened on the surface of the sealing frame 142, the guiding tube 146 is fixedly installed on the left side of the sealing frame 142, and the moving frame 148 is fixedly installed on the left side of the placement rack 1. By using a fixed amount, it can ensure that there will be no excessive chemical residues on the ground after each cleaning. After scraping off the residues, the grinding process can be made smoother.

[0027] The interior of the storage box 141 is provided with an epoxy resin cleaning agent. A third spring is provided between the sealing frame 142 and the sealing plate 143, and the third spring can drive the sealing plate 143 to reset. The interior of the guide tube 146 is provided with a cross rubber valve, and the guide tube 146 penetrates through the left top of the placing rack 1.

[0028] The L-shaped plate 144 contacts the limiting disc 11. A rack 147 is fixedly installed at the bottom of the L-shaped plate 144. The L-shaped plate 144 penetrates through the inner and outer walls of the storage box 141. The cross rubber valve deforms under the extrusion of the epoxy resin cleaning agent entering the interior of the guide tube 146.

[0029] The dust collection device includes a dust collection pipe 151, a dust collection rod 152, a gear 153, a separation plate 154, a rotating rod 155, an arc-shaped panel 156 and a convex block 157. The dust collection pipe 151 is fixedly installed on the left side of the dust collection device 4. The dust collection pipe 151 penetrates through the left and right walls of the placing rack 1. The dust collection rod 152 rotatably penetrates through the top of the dust collection pipe 151. The dust collection rod 152 penetrates through the left top of the placing rack 1. The gear 153 is fixedly installed on the circumferential surface of the dust collection rod 152. The separation plate 154 is fixedly installed on the inner wall of the dust collection pipe 151.

The convex block 157 is fixedly installed on the circumferential surface of the dust collection rod 152. The rotating rod 155 pushing the particulate matter to separate from the separation plate 154 can prevent excessive accumulation of particulate matter at the bottom of the separation plate 154, thereby improving the dust collection effect of the dust collection device 4.

[0030] The gear 153 meshes with the rack 147. The arc-shaped panel 156 is elastic. The arc-shaped panel 156 contacts the convex block 157. The dust collection device 4 operates to collect the dust generated by the frictional impact.

[0031] During the operation of this embodiment: The limiting disc 11 moves away from the adjusting pipe 5 and contacts the L-shaped plate 144 and squeezes the L-shaped plate 144. The L-shaped plate 144 moves away from the limiting groove 71 under the extrusion of the limiting disc 11. The movement of the L-shaped plate 144 away from the limiting groove 71 drives the movement of the sealing plate 143. The movement of the sealing plate 143 pulls the third spring. The third spring deforms and stores energy on the side where the sealing plate 143 is located. At the same time, the sealing plate 143 moves away from the contact with the sealing hole 145 and seals a part of the space in front of the sealing frame 142 and the quantitative epoxy resin cleaning agent. The sealing plate 143 continues to move and squeezes the quantitative epoxy resin cleaning agent inside the sealing frame 142. The quantitative epoxy resin cleaning agent inside the sealing frame 142 enters the guiding pipe 146 under the action of the sealing plate 143. The epoxy resin cleaning agent entering the guiding pipe 146 squeezes the cross rubber valve. The cross rubber valve deforms under the extrusion of the epoxy resin cleaning agent entering the guiding pipe 146. The deformation of the cross rubber valve releases the seal of the guiding pipe 146. After the seal of the guiding pipe 146 is released, the quantitative epoxy resin cleaning agent inside the sealing frame 142 is sprayed towards the area to be polished through the guiding pipe 146. At the same time, when the U-shaped rod 3 moves horizontally and drives the placement rack 1 to move through the roller 2, the movement of the placement rack 1 drives the movement of the moving frame 148. The movement of the moving frame 148 cooperates with the epoxy resin cleaning agent to scrape off the epoxy resin residue in the area to be polished.

[0032] When the L-shaped plate 144 moves away from the limiting groove 71 under the extrusion of the limiting disc 11, the movement of the L-shaped plate 144 away from the limiting groove 71 drives the movement of the rack 147. The movement of the rack 147 squeezes the gear 153. The gear 153 rotates under the extrusion of the rack 147. The rotation of the gear 153 drives the rotation of the dust suction rod 152. The rotation of the dust suction rod 152 drives the rotation of the rotating rod 155. The rotation of the rotating rod 155 pushes the larger particles at the bottom of the separation plate 154. The larger particles at the bottom of the separation plate 154 are separated from the separation plate 154 under the push of the rotating rod 155. At the same time, the rotation of the dust suction rod 152 drives the rotation of the convex block 157. The rotation of the convex block 157 contacts and rubs against the arc-shaped panel 156 to generate vibration. The vibration of the arc-shaped panel 156 drives the vibration of the separation plate 154. The vibration of the separation plate 154 shakes off the larger particles at the bottom of the separation plate 154. And when the anti-static polishing device 7 operates, it synchronously drives the dust suction device 4 to operate. The dust suction device 4 operates to collect the dust generated by the friction.
