The cradle frame is equipped with multiple grinding heads, each of which includes a grinding wheel and a grinding motor. The grinding heads are installed in the cradle frame through a vertical lifting device. The vertical lifting device includes a parallelogram mechanism, and the parallelogram mechanism is connected to a cylinder. The parallelogram mechanism includes an upper U-shaped arm and a lower U-shaped arm parallel to each other, one end of the upper U-shaped arm and one end of the lower U-shaped arm are respectively hinged to the cradle frame, and the other end of the upper U-shaped arm and the other end of the lower U-shaped arm are respectively hinged to the vertical plate, and the grinding motor is fixed to the vertical plate. The grinding head presses down on the workpiece from top to bottom to grind the workpiece.

[0004] Therefore, it is necessary to propose a new type of equipment to overcome the existing technical problems. Utility Model Content

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] refer to Figures 1 to 5 As shown, a plate surface treatment device includes a grinding wheel 7, the upper end of which is a flat grinding surface, a driving motor 11 for driving the grinding wheel to rotate, and a dust collecting cup 8 installed on a lifting device, the driving shaft of the grinding wheel is arranged perpendicular to the horizontal plane, and passes through the dust collecting cup through the dust inlet at the top of the dust collecting cup 8 and is connected to the driving motor located below the dust collecting cup; the dust generated by the grinding wheel can fall into the dust collecting cup through the dust inlet.

[0024] Wherein, illustratively, a base frame 3 is also included for supporting the grinding unit, the frame and the lifting motor as a whole.

[0025] In some embodiments, the driving shaft of the grinding disc is connected to the driving motor through the bottom hole of the dust collecting cup, and is connected to the bottom hole through a rotating support, and the rotating support and the bottom hole are sealed.

[0026] As a preferred embodiment, the lifting device may include a bottom structure 16 and a top structure 14 connected to the bottom structure via vertically arranged connecting rods 17.

[0027] In one embodiment, a buffer mechanism 9 is mounted on the connecting rod 16. For example, a spring mechanism is adopted. The top end of the buffer mechanism abuts against the bottom end of the top structure, and the bottom end of the buffer mechanism is connected to the top end of the bottom structure. The drive motor and the dust cup are installed on the top structure.

[0028] Wherein, the connecting rod can be realized by using a bolt or a screw, and there is at least one.

[0029] In one embodiment, the bottom of the top structure can be connected to the upper side of the bottom structure through the connecting rod via a vertically bent connecting edge, and a horizontal mounting plate perpendicular to the lifting device is fixed on the mounting side of the grinding unit of the top structure, and the bottom of the dust collecting cup is fixed on the horizontal mounting plate, and the motor frame of the driving motor is fixed to the mounting side of the grinding unit of the top structure, and the driving motor is located below the horizontal mounting plate.

[0030] Through the above solution, floating contact can be formed between the grinding disc and the workpiece during the grinding process, thereby preventing damage to the workpiece or the grinding disc caused by rigid contact.

[0031] Among them, the lifting device can be driven to lift by a linear mechanism, or driven to lift by a rotary mechanism. For example, it is realized by a rotary mechanism, such as a lifting motor 5 and a reducer 4 driven to rotate. In order to cooperate with the motor-driven lifting, an eccentric lifting mechanism 6 can be arranged on one side of the bottom structure. The eccentric lifting mechanism is connected to the rotary drive mechanism and is driven to rotate. In this way, through the rotation of the eccentric lifting mechanism, the bottom structure and the top structure can be lifted and lowered along the linear guide rail 12 on the frame 13.

[0032] One side of the top structure is fixed to the slider 10 of the linear guide 12, enabling the top structure to be raised and lowered via the linear guide. The frame 13 is formed by welding or bolting channel steel. The lifting motor and other lifting drive components are mounted on the horizontal frame of the frame 13, and the lifting device and grinding unit are mounted on the vertical frame of the frame.

[0033] Among them, the eccentric lifting mechanism can include a rotating plate connected to the drive shaft at one end, and a roller 15 arranged near the other end of the rotating plate. When the rotating plate is driven to rotate, the roller is rotated and lifted, and the roller is connected to the bottom structure through the roller. The bottom structure is driven to lift and lower by rotation, thereby realizing the lifting of the lifting device, and then lifting and lowering the grinding mechanism and the dust collecting cup as a whole.

[0034] Exemplarily, the bottom structure 16 is a trough body with a U-shaped transverse cross section, the roller extends into the trough body through the slot opening, and the wheel surface thereof is opposite to the inner surface of the trough wall of the trough body.

[0035] As an embodiment, the side of the dust collecting cup has a dust suction port, and the dust collector 1 is connected to the dust collection pipe 2 through the dust suction port. In this way, during the grinding process, the dust in the dust collecting cup can be collected by starting the vacuum cleaner.

[0036] The plate surface treatment device of the present invention can realize the lifting and lowering of the grinding disc, and since the top surface of the grinding disc is a flat grinding surface, when the grinding disc is driven to rise to a certain position and contacts the grinding surface of the workpiece to be polished, it is rotated by the driving motor, which can realize effective grinding of the workpiece to be polished, and the dust generated by grinding directly falls into the dust cup, so that grinding is carried out without flying dust and polluting the environment.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
