Description

Technical Field

[0001] The utility model relates to the technical field of terrazzo brick polishing, in particular to an automatic loading and unloading palletizer for a terrazzo brick machine. Background Art

[0002] Terrazzo brick is a decorative material that combines traditional terrazzo technology with modern ceramic tile production technology. It is widely welcomed for its unique texture, wear resistance, anti-slip property, and diverse colors. It is widely used in many fields such as home decoration, commercial spaces, and public areas.

[0003] Common terrazzo polishing equipment includes a linear polishing machine and an automatic rotary terrazzo polishing machine.

[0004] For traditional automatic rotary terrazzo polishing machines, manual operation is mostly relied on for loading and unloading plates. Moreover, the polished terrazzo bricks still need to be stacked by a special person. This not only has low efficiency but also high labor intensity, making it difficult to meet the needs of large-scale production. At the same time, there are also problems such as unstable stacking quality and low stacking efficiency in manual stacking, which seriously restricts the automation and intelligent level of the terrazzo brick polishing production line. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings of high labor intensity of manual loading and unloading of plates, poor stacking effect, and low efficiency in the polishing process of terrazzo bricks by an existing automatic rotary terrazzo polishing machine, and to propose an automatic loading and unloading palletizer for a terrazzo brick machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0013] In a possible design, the first driving component includes a support plate, which is fixedly arranged at the top of the support frame. A first motor is fixedly arranged at the top of the support plate. The output end of the first motor is fixedly connected with a transmission arm. Fixed frames are fixedly arranged on the top of the first moving plate, and chutes are opened on the fixed frames. A pulley is arranged on one side of the transmission arm, and the pulley is located in the chute. The transmission arm is driven by the first motor to move in the chute, so that the fixed frame can move left and right.

[0014] In a possible design, the lifting component includes two first moving rods, which penetrate through the corresponding limiting tubes and are slidably connected with the inner walls of the limiting tubes. First connecting rods are fixedly arranged at the top and bottom of the two first moving rods. Fixed rods are fixedly arranged at the top of the two first connecting rods. A first chain is fixedly arranged between the two fixed rods. Among them, the bottom of the first connecting rod located below is rotatably connected with a first bracket, and the bottom of the first bracket is fixedly connected with the suction cup.

[0015] In a possible design, the second driving component includes a second motor, which is fixedly arranged on the top of the first moving plate. A first driving gear is fixedly sleeved on the output end of the second motor, and the first driving gear is meshed with the corresponding first chain.

[0016] In a possible design, first driven gears corresponding to the first chain are arranged on the tops of the first moving plate and the second moving plate. The first driven gears are located on the radial side of the first driving gear, and the first driven gears are meshed with the corresponding first chains. By setting the first driven gears, the first chain is stable during the movement.

[0017] In a possible design, the palletizing assembly includes a third motor fixedly arranged on the top of the third moving plate. A transmission gear is fixedly sleeved on the output end of the third motor. A rack is fixedly arranged on one inner wall of the groove. The transmission gear is meshed with the rack.

The second driven gear is meshed with the second chain. A second driving gear is arranged on the top of the third moving plate. The second driving gear is located on the radial side of the second driven gear. The second chain is located between the second driving gear and the second driven gear and is meshed with the second driving gear.

[0020] In a possible design, a feeding placement rack is fixedly arranged on the top of the brick grinding machine body near one side of the conveyor for placing the water mill bricks waiting for water grinding. A rolling rack is fixedly arranged on the inner wall of the side of the support frame away from the conveyor for placing the water mill bricks that have completed water grinding. The width of the rolling rack is greater than the width of two water mill bricks, facilitating the water mill bricks to be placed in a square shape and convenient for grasping four water mill bricks at a time to complete palletizing.

[0021] In this application, the water mill bricks to be water ground are conveyed to a preset position by the conveyor. Then, the first driving assembly on the first moving plate is started. The first motor drives the transmission arm to rotate. The pulley on the transmission arm moves in the chute in the fixed frame on the first moving plate, thereby driving the first moving plate to move above the water mill bricks to be water ground. Then, the lifting assembly on the first moving plate works. The second motor is started to drive the first driving gear to rotate. Then, through the transmission of the first chain and the first driven gear, the two first moving rods move up and down in the limiting tubes, driving the suction cups to descend and adsorb the water mill bricks. Then, the first motor and the second motor are started in reverse to move the grasped water mill bricks to the feeding placement rack on the brick grinding machine body and place them on the feeding placement rack. Then, the first moving plate continues to move above the water mill bricks to be water ground through the first driving assembly and the lifting assembly on it to wait for grasping.

The brick grinding machine body starts to grind the water mill bricks. After the grinding is completed, the second moving plate moves, and another lifting assembly on it grabs the water mill bricks that have been ground in the brick grinding machine. During this process, a lifting assembly on the second moving plate will simultaneously grab a water mill brick to be ground. And during the movement of the second moving plate, the ground water mill bricks are placed on the rolling rack, and the water mill bricks to be ground are placed at the entrance position of the brick grinding machine body. Moreover, the first bracket for installing the suction cup can rotate on the fixed rod, so that its angle can be adjusted during grinding and placement, which is convenient for grinding and placing. Among them, the first driving assembly and the lifting assembly on the second moving plate have the same principle as the first driving assembly and the lifting assembly on the first moving plate.

[0023] When there are enough water mill bricks on the rolling rack, the palletizing assembly on the third moving plate is started. The third motor drives the transmission gear to mesh with the rack, so that the third moving plate moves along the groove on the support frame to the specified palletizing position. The fourth motor in the palletizing assembly works, and through the transmission of the second driving gear and the second driven gear, drives the second chain to move, and then makes the nine suction cups located below descend simultaneously and adsorb the water mill bricks that have completed the grinding. Then, the third moving plate moves to the palletizing area according to the preset program, the suction cups rise and release the water mill bricks, and the palletizing operation is completed.
