[0033] A rotating frame, the rotating frame is rotatably mounted on the lifting frame, an adjusting block is movably arranged on the rotating frame, a connecting rod is hingedly arranged on the adjusting block, a piston rod hingedly connected to the connecting rod is arranged on the piston plate, and an adjusting mechanism for adjusting the position of the adjusting block is arranged on the rotating frame;

[0034] A transmission mechanism is arranged on the lifting frame and is used to connect the driving mechanism with the rotating frame. A clutch assembly is arranged on the lifting frame, and the clutch assembly acts on the transmission mechanism to adjust the transmission state between the driving mechanism and the rotating frame.

[0035] The lifting frame is driven by the lifting mechanism to drive the grinder and the nozzle to approach the glass on the conveying roller frame, and the screw rod is driven to rotate by the driving mechanism. During the rotation of the screw rod, the slide is driven to drive the grinder and the nozzle to move on the glass surface, and the grinder polishes the glass. During the movement of the nozzle, the clutch assembly acts on the transmission mechanism to make the driving mechanism connected with the rotating frame through the transmission mechanism. The driving mechanism drives the rotating frame to rotate. During the rotation of the adjusting block driven by the rotating frame, the piston disc is driven to reciprocate through the connecting rod and the piston rod. In conjunction with the one-way valve structure on the feeding pipe and the discharging pipe, the piston disc continuously extracts the polishing agent at the material box and extrude the polishing agent through the discharging pipe and the nozzle, so as to realize the automatic spraying of the polishing agent. The position of the adjusting block is adjusted by the adjusting mechanism to adjust the reciprocating stroke distance of the piston rod, thereby adjusting the spraying amount of the polishing agent, and the transmission state between the driving mechanism and the rotating frame can be cut off at any time through the clutch assembly to stop the spraying of the polishing agent, so as to realize the coordinated cooperation between the spraying of the polishing agent and the grinding work, and improve the automation degree and work efficiency of the glass polishing work. Among them, the driving mechanism drives the screw rod to rotate reciprocatingly, which can drive the grinding machine and the nozzle to move reciprocatingly through the slide. The one-way valve at the feed pipe can only allow materials to be transported from the material box to the left chamber, and the one-way valve at the discharge pipe can only allow materials to be transported from the left chamber to the nozzle.

[0036] Embodiment 2:

[0037] Reference Figures 1 to 6 Combined with the technical solution of Example 1, in this embodiment, the transmission mechanism includes a main gear, a driven gear, a driven bevel gear and a driving bevel gear. The main gear is coaxially arranged with the screw and rotates with the screw. The driven gear and the driven bevel gear are both rotatably installed on the lifting frame. The driving bevel gear is coaxially arranged with the rotating frame and drives the rotating frame to rotate. The main gear is meshed with the driven gear, and the driven bevel gear is meshed with the driving bevel gear. The clutch assembly is used to adjust the transmission state between the driven gear and the driven bevel gear.

[0038] The driving mechanism drives the screw to rotate and drives the main gear to rotate at the same time. The main gear drives the driven gear to rotate. When the clutch assembly drives the driven gear and the driven bevel gear to be connected, the driven gear drives the rotating frame to rotate through the driven bevel gear and the driving bevel gear. The rotating frame drives the adjusting block to rotate and drives the piston disc to move back and forth through the connecting rod and the piston rod. In conjunction with the one-way valve structure on the feed pipe and the discharge pipe, the piston disc continuously extracts the polishing agent from the material box and extrude the polishing agent through the discharge pipe and the nozzle, thereby realizing automatic spraying of the polishing agent. When the clutch assembly cuts off the transmission state between the driven gear and the driven bevel gear, the polishing agent spraying work is stopped.

[0039] Specifically, the driven gear is provided with a rotating shaft, and the rotating shaft is rotatably installed on the lifting frame. The driven bevel gear is provided with a through hole for the rotating shaft to pass through. A slide is movably provided on the rotating shaft, and the slide rotates with the rotating shaft. A transmission bevel gear is provided on the slide, and a bevel tooth groove for the transmission bevel gear to engage is provided on the driven bevel gear, and the clutch assembly is used to drive the slide to move.

[0040] The clutch assembly drives the bevel tooth groove of the slide box to move until the transmission bevel gear on the slide engages with the bevel tooth groove on the driven bevel gear, thereby realizing the transmission connection between the driven gear and the driven bevel gear. At this time, the driving mechanism can drive the rotating frame to rotate to spray the polishing agent. When the clutch assembly drives the slide away from the bevel tooth groove, the transmission connection between the driven gear and the driven bevel gear can be cut off, and the spraying of the polishing agent can be stopped.

[0041] Specifically, the clutch assembly includes an electromagnet, an iron ring and a spring, wherein the spring is arranged on the rotating shaft, and the spring pushes the slide to drive the transmission bevel gear to engage with the bevel tooth groove, the iron ring is arranged on the slide, and the electromagnet is arranged on the lifting frame, and the electromagnet is used to attract the iron ring to drive the transmission bevel gear away from the bevel tooth groove.

[0042] When the electromagnet is powered off, the spring pushes the slide to drive the transmission bevel gear to engage with the bevel tooth groove, thereby realizing the transmission connection between the driven gear and the driven bevel gear. At this time, the driving mechanism can drive the rotating frame to rotate to spray the polishing agent. When the electromagnet is energized and attracts the iron ring to drive the slide away from the bevel tooth groove, the transmission connection between the driven gear and the driven bevel gear can be cut off, and the spraying of the polishing agent can be stopped.

[0043] Specifically, an installation cavity is provided on the rotating shaft, a slider is slidably provided in the installation cavity, a plurality of slide grooves are provided on the rotating shaft, a plurality of connecting parts are provided on the slider, the connecting parts pass through the slide grooves and are connected to the slide seat, the spring is provided in the installation cavity, and the spring is used to push the slider to drive the transmission bevel gear to engage with the bevel tooth groove.

[0044] Through the cooperation of several slide grooves and several connecting parts, the slide seat can only move relative to the rotating shaft but cannot rotate relative to the rotating shaft, which is conducive to cooperating with the clutch assembly, the power transmission bevel gear and the bevel tooth groove to realize the transmission state adjustment work between the driven gear and the driven bevel gear.

[0045] Embodiment 3:

[0046] Reference Figures 1 to 6 Combining the technical solutions of Example 1 and Example 2, in this embodiment, the adjusting mechanism includes a driving motor and a screw, the screw is rotatably mounted on the rotating frame, the adjusting block is provided with a screw hole that cooperates with the screw, and the driving motor is transmission-connected to the screw and drives the screw to rotate.

[0047] The screw is driven to rotate by a driving motor. During the rotation of the screw, it cooperates with the screw hole on the adjusting block to drive the adjusting block to slide relative to the rotating frame, thereby adjusting the position of the adjusting block on the rotating frame, that is, adjusting the swing radius of the connecting rod, thereby adjusting the stroke distance of the piston disc, and realizing the adjustment of the polishing agent spraying amount.

[0048] Specifically, the driving mechanism is a servo motor.

[0049] The use of a servo motor with adjustable speed facilitates the adjustment of the speed of the screw and the rotating frame to adjust the moving speed of the grinding machine and the nozzle and the spraying speed of the polishing agent.

[0050] Specifically, the lifting mechanism is a hydraulic cylinder.

[0051] The lifting frame can be driven up and down by a hydraulic cylinder to realize the lifting operation of the grinding wheel machine and the spray head, so as to facilitate the polishing agent spraying and grinding and polishing work close to the glass on the conveying roller frame.

[0052] Specifically, a control panel is provided on the frame, and the control panel is electrically connected to the lifting mechanism, the driving mechanism, the grinding machine, the adjusting mechanism and the clutch assembly respectively.

[0053] The working states of the lifting mechanism, the driving mechanism, the grinding wheel machine, the adjusting mechanism and the clutch assembly can be adjusted through the control panel according to work needs, providing convenience for automatic glass polishing.

[0054] Specifically, the nozzle and the grinding machine are sequentially arranged on the slide along the conveying direction of the conveying roller frame.

[0055] That is, the nozzle is set in front of the grinding machine. When the conveyor roller frame transports the glass, the nozzle first sprays the polishing agent on the glass. The sprayed glass then moves to the grinding machine for grinding. When the grinding machine moves with the slide for grinding, the slide simultaneously drives the nozzle to move to the next position of the glass for spraying the polishing agent, thereby realizing the coordinated cooperation of the polishing agent spraying work and the grinding work, improving the continuity of the glass grinding and polishing work, and further improving the work efficiency of the glass polishing.

[0056] The above are only preferred embodiments of the present invention, and do not limit the present invention in any form.
