[0008] Further, the automatic loading machine is located above the upper right side of the upper sheet conveyor. The blanking cutting machine realizes the feeding action through the upper sheet conveyor. An automatic hole opening and grinding machine and an edge grinding machine are arranged on the multi-knife cutting machine.

[0009] Further, the number of the semi-automatic turntables is two, and the two semi-automatic turntables are respectively located in front of and behind the first positioning conveyor. The number of the hole opening machines is two, and the two hole opening machines are respectively located in front of and behind the four-meter conveyor. The number of the automatic turntables is two, and the two automatic turntables are respectively located in front of and behind the second positioning conveyor.

[0010] Further, the length of the conveying turntable is three meters, and a universal wheel frame is fixedly installed between the conveying turntable and the forty-five-degree cutting machine.

[0011] Further, the first cleaning machine and the second cleaning machine are equipment of the same model. The model of the first cleaning machine is LG-QX800, and the model of the front edge grinding machine is LG-YH3000.

[0012] Further, a glue rack is arranged inside the glue room, and a dust removal device is fixedly installed inside the glue room.

[0013] A processing technology of a high-precision quartz stone tabletop flexible automatic production line includes the following steps:

[0014] Step 1, plate cutting; Step 2, hole opening; Step 3, forty-five-degree cutting; Step 4, cleaning; Step 5, automatically turning the plate 180 degrees; Step 6, gluing; Step 7, edge grinding and grooving; Step 8, cleaning and drying; Step 9, inspection, film pasting and packaging;

[0015] In Step 1, the plate is automatically loaded onto the upper sheet conveyor through the automatic loading machine. The upper sheet conveyor transfers the plate to the blanking cutting machine for automatic cutting into the required processing size standard. After cutting, it is transferred to the multi-knife cutting machine for multi-knife slicing cutting, and then transferred to the horizontal cutting machine for horizontal length cutting to complete the cutting process;

[0016] In step two, the cut sheet is transferred to a hole-opening machine for opening the basin hole. The sheets that do not require hole opening are normally conveyed by the first positioning conveyor to the four-meter conveyor to enter the next process. The sheets that need to be opened are transferred to the entrance of the hole-opening machine by a semi-automatic turntable and then conveyed out through an automatic turntable.

[0017] In step three, after the sheet is conveyed to the conveying turntable, the sheets that need to be cut at 45 degrees are automatically lifted, conveyed automatically by a belt to a caster stand, and then enter a 45-degree cutting machine for processing. The sheets that do not require 45-degree cutting are directly fed into the next process.

[0018] In step four, the sheets after 45-degree cutting are cleaned and dried in a cleaning machine. The cleaning and drying treatment can make the next bonding process more convenient, faster, and the bonding smoother.

[0019] In step five, the sheet is clamped and turned over by a turning machine to automatically turn the sheet 180 degrees.

[0020] In step six, the sheet enters the glue-bonding room for bonding process operations. Multiple dust removal and odor removal devices are also configured in the glue-bonding area to ensure a dust-free state in the glue-bonding room, and at the same time remove harmful, toxic, and irritating odors. After drying, it is transported to the next process.

[0021] In step seven, the bonded sheets automatically flow to the front-edge grinding machine, where operations such as grinding, grooving, and chamfering are performed. After the parts that need to be ground are ground, the tabletop is formed.

[0022] In step eight, the sheets after grinding and grooving are then automatically conveyed into a cleaning machine for cleaning and drying. The sheets that do not require front-edge grinding are directly conveyed into the cleaning machine.

[0023] In step nine, the cleaned sheets automatically flow to the next process for calculating the total number of tabletops. Then, the formed tabletops are laminated, and after lamination, they are packaged and then automatically shipped and transferred or stacked in the warehouse.

[0024] Furthermore, in step one, the remaining edge materials generated by cutting flow out through the second automatic conveyor. The water retaining strips obtained by multi-knife slicing are automatically sorted into the water retaining strip conveyor and then transferred to a water retaining strip grinding machine for grinding and chamfering treatment, and then conveyed to the glue-bonding room through the four-meter conveyor for bonding treatment.

[0041] A processing technology of a high-precision quartz stone tabletop flexible automatic production line includes the following steps:

[0042] Step 1: Sheet cutting; Step 2: Punching; Step 3: 45-degree cutting; Step 4: Cleaning; Step 5: Automatically flip the sheet by 180 degrees; Step 6: Gluing; Step 7: Edge grinding and grooving; Step 8: Cleaning and drying; Step 9: Inspection, film laminating and packaging;

[0043] In Step 1, the sheet is automatically loaded onto the upper sheet conveyor by the automatic loading machine. The upper sheet conveyor transfers the sheet to the cutting machine to be automatically cut into the required processing size standard. After cutting, it is transferred to the multi-knife cutting machine for multi-knife slicing, and then transferred to the horizontal cutting machine for horizontal length cutting to complete the cutting process;

[0044] The remaining edge materials generated by cutting are discharged by the second automatic conveyor. The water retaining strips obtained by multi-knife slicing enter the water retaining strip conveyor through automatic sorting, and then are transferred to the water retaining strip edge grinding machine for edge grinding and chamfering, and are transported to the gluing room by the four-meter conveyor for bonding treatment;

The sheets that do not need punching are normally conveyed by the first positioning conveyor to the four-meter conveyor to enter the next process. The punched sheets are transferred to the entrance of the punching machine by the semi-automatic turntable, and then conveyed out through the automatic turntable;

[0046] In Step 3, after the sheet is conveyed to the conveying turntable, the sheets that need to be cut at 45 degrees are automatically lifted, conveyed to the universal wheel frame by the belt, and then enter the 45-degree cutting machine for processing. The sheets that do not need 45-degree cutting are directly fed into the next process;

[0047] In Step 4, the sheet after 45-degree cutting is cleaned and dried in the cleaning machine. The cleaning and drying treatment can make the next bonding process more convenient, faster and smoother;

After drying, it is transferred to the next process;

[0050] In Step 7, the bonded sheet automatically flows to the front edge grinding machine, and at this time, operations such as edge grinding, grooving and chamfering are carried out. After grinding the parts that need to be edge-ground, the tabletop is formed;

[0051] In Step 8, the sheet after edge grinding and grooving is then automatically conveyed into the cleaning machine for cleaning and drying. The sheets that do not need front edge grinding are directly conveyed into the cleaning machine;

[0052] In step nine, the cleaned sheets automatically flow to the next process for calculating the total number of countertops. Subsequently, the formed countertops are laminated, and after lamination, they are packaged and then automatically shipped and transferred or stacked in the warehouse.

Multiple dust removal and odor removal devices are also configured in the adhesive area to ensure a dust-free state in the adhesive room, and at the same time remove harmful, toxic and irritating odors. After drying, it is transferred to the next process; In Step 7, the bonded sheet automatically flows to the front edge grinding machine, where edge grinding, grooving and chamfering operations are carried out. After the part that needs to be edge ground is ground, the tabletop is formed; In Step 8, the sheet after edge grinding and grooving is then automatically conveyed into the cleaning machine for cleaning and drying. The sheets that do not need front edge grinding are directly conveyed into the cleaning machine; In Step 9, the cleaned sheet automatically flows to the next process for calculating the total number of tabletops, and then the formed tabletop is pasted with film. After film pasting, it is packaged, and then automatically shipped and transferred or stacked in the warehouse.

8. The processing technology for a flexible automatic production line of high-precision quartz countertops according to claim 7, characterized in that: In Step 1, the remaining edge materials generated by cutting flow out through the second automatic conveyor. The water retaining strips obtained by multi-knife slicing are automatically sorted into the water retaining strip conveyor, and then transferred to the water retaining strip edge grinding machine for edge grinding and chamfering treatment, and then conveyed to the adhesive room through the four-meter conveyor for bonding treatment.
