A cutter holder 2 is slidably connected to the transverse cutting machine 11, and the cutter holder 2 reciprocates along a transverse guide rail 11a on the transverse cutting machine 11 to cut the glass ribbon 10 transversely.
A pair of blade holders 2 are slidably connected to a slitter rail 12a of the slitter 12, and the pair of blade holders 2 of the slitter 12 are moved to the edges on both sides of the glass ribbon 10 conveyed on the glass conveying table, and then locked to the slitter rail 12a by locking pins, so that the edges on both sides of the glass ribbon 10 are cut in a direction parallel to the direction in which the glass ribbon 10 is moved.

The output end of the telescopic mechanism 6a is connected with a bottom plate 6b which is horizontally distributed, and the bottom plate 6b is of a rectangular structure. The longitudinal direction of the bottom plate 6b on the transverse cutting machine 11 and the axis of the guide rail 11a are distributed in parallel, and the longitudinal direction of the bottom plate 6b on the slitter 12 and the axis of the slitter guide rail 12a are mutually perpendicular. A vertically distributed tool rest 6d is connected to the bottom surface of the bottom plate 6b, and a tool wheel 6e is connected to the lower end of the tool rest 6 d. The knife rest is a detachable knife rest, and knife wheels with different diameters, different angles and different outer edge shapes can be replaced according to the cutting process.
The bottom plate 6b is fixedly connected with an annular air outlet mechanism, the air outlet mechanism comprises air outlet pipes 16a which are distributed in a rectangular annular shape, the air outlet pipes 16a are vertically distributed with the bottom plate 6b, and the inner wall of the inner ring of the air outlet pipes 16a is fixedly connected with the thickness end faces on two sides of the length edge of the bottom plate 6b. An air outlet 16b bent toward the blade holder 6d is provided at the air outlet end below the air outlet pipe 16 a.
A vertically distributed coating head 6f is mounted on the width edge of one end of the bottom plate 6b, and a vertically distributed adsorbing head 6c is mounted on the width edge of the other end of the bottom plate 6b. The outer walls of the coating head 6f and the adsorption head 6c are attached to the inner walls of the two ends of the air outlet pipe 16 a. The liquid inlet end of the adsorption head 6c and the liquid outlet end of the coating head 6f are in the same horizontal plane and are higher than the air outlet 16b by a certain distance.
The horizontal distance between the suction head 6c and the tool rest 6d is larger than the horizontal distance between the tool rest 6d and the coating head 6 f. That is, the length of the horizontal distance Lc from the cutting point of the cutter wheel 6e to the liquid outlet end of the coating head 6f is smaller than the horizontal distance Ld from the cutting point of the cutter wheel 6e to the liquid inlet end of the adsorption head 6c. The liquid suction position is far away from the cutting point of the cutter wheel, so that the damage of suction force to the shape of the liquid film is reduced, and the stability of the working width and the working thickness of the liquid film is maintained.
The machine frames of the transverse cutting machine 11 and the longitudinal cutting machine 12 are respectively connected with a platform 1, and each platform 1 is provided with a liquid supply tank 3, a liquid return tank 4 and a fan 5. The liquid in the liquid supply tank 3 is a mixed liquid of water and ethanol, and the mixing proportion is 10% -40% of water 60% -90% of ethanol, preferably 70% of water and 30% of ethanol. For convenience of view, the air duct 5a, the liquid outlet pipe 3a, the liquid return pipe 4a, the air volume control valve 5b, the pump body 7 and the flow control valve 8 are not shown in fig. 1.
The air outlet pipe 16a is communicated with the air outlet pipe of the corresponding fan 5 through an air pipe 5a, and an air quantity control valve 5b is also arranged on the air outlet pipe. The coating head 6f is communicated with the corresponding liquid supply tank 3 through a liquid outlet pipe 3a, the adsorption head 6c is communicated with the liquid return tank 4 through a corresponding liquid return pipe 4a, and the liquid outlet pipe 3a and the liquid return pipe 4a are respectively provided with a corresponding matched pump body 7 and a flow control valve 8.

A group of spiral telescopic pipe sections are arranged on the air pipe 5a, the liquid outlet pipe 3a and the liquid return pipe 4a so that the cutter holder 2 has a movement allowance when moving. In order to ensure the air outlet efficiency of the air outlet mechanism, two air pipes 5a are connected to the air outlet mechanism connected to each bottom plate.
The fan 5, the air quantity control valve 5b, the pump body 7 and the flow control valve 8 are connected with control consoles on the corresponding transverse cutting machine 11 and the slitter 12 through wires to form electric signal connection control cooperation. Because the slitter is provided with two knife holders and two integrated knife heads, the number of the air pipes 5a, the liquid outlet pipes 3a and the liquid return pipes 4a is two, and the power and the volume of the liquid supply tank 3, the liquid return tank 4 and the fan 5 are also twice that of the transverse cutting machine platform.
Due to the wind sprayed out from the air outlet, an annular air curtain 14 is formed on the glass ribbon 10 below the air outlet mechanism, and due to the existence of the air curtain 14, liquid discharged from the coating head can only form a liquid film 9 with a certain thickness on the inner side of the air curtain under the blocking of the air curtain 14, and the thickness of the liquid film 9 in the inner ring of the air outlet mechanism is controlled by controlling the air outlet quantity of the air outlet mechanism, the liquid outlet quantity of the coating head and the liquid suction quantity of the adsorption head.
A cutting method of a float glass production line cutting device is characterized by comprising the following steps of: it comprises the following steps of the method,
s1, according to the specification and cutting requirements of the glass ribbon 10 conveyed on the glass conveying table, locking two cutter holders on the slitter at proper positions of guide rails of the slitter, wherein the cutting direction of a wheel knife on the cutter holders is parallel to the moving direction of the glass ribbon 10 so as to cut edges on two sides of the glass ribbon 10.
S2, inputting flow data of the air pipe 5a, the liquid outlet pipe 3a and the liquid return pipe 4a into a control console according to cutting requirements of the glass ribbon 10.
S3, starting the fan 5 through a control console, controlling the flow control valve 8 to be opened to a proper flow, and forming an air curtain 14 distributed in a closed loop shape outside the cutter wheel 6e through an air outlet mechanism.
S4, sequentially starting the liquid outlet pipe 3a and the pump body 7 on the liquid return pipe 4a through a control console, so that a liquid film 9 covering a cutting point 15 of the cutter wheel 6e is formed on the upper surface of the glass ribbon 10 inside the air curtain 14.
Because the air outlet mechanism moves synchronously with the cutter wheel 6e, and the coating head and the adsorption head are both positioned at the inner side of the air curtain 14, the liquid film 9 also moves together with the air curtain 14.
And S5, after the liquid film layer 9 is formed, the control console controls and maintains the output power of the pump body 7 on the liquid outlet pipe 3a and the liquid return pipe 4a, so that the thickness of the liquid film layer 9 is ensured to be constant.
S6, controlling the glass conveying table to start transferring the glass ribbon 10 through the control table, and simultaneously starting the integrated cutter head 6 on the transverse cutting machine 11 and the longitudinal cutting machine 12 to cut the glass ribbon 10.
The following are the changes of data when cutting glass with different thickness by using cutter wheels with different sizes:
when the working width W of the liquid film 9 is optimized to be 10mm constant, the working thickness H is characterized by the following examples:
a: selecting a cutter wheel (with the diameter of 6.22mm and the angle of 145 DEG), scribing the contact point 15 on the glass 80 with the thickness of 6mm at the moving speed of 220mm/s, and ensuring the working thickness H of the liquid film 9 to be 1.5mm; when the moving speed of the contact point 15 is increased to 450mm/s, the working thickness H of the liquid film is increased to 3.0mm;
b: selecting a cutter wheel (angle is 145 degrees, cutting glass with the thickness of 8 mm), and when the diameter of the cutter wheel is 6.22mm, the working thickness of the liquid film is 1.6mm; when the diameter of the cutter wheel is 12.7mm, the working thickness of the liquid film is 3.3mm;
c: selecting a cutter wheel (the diameter is 5.84mm, and a thick glass plate is cut) and when the angle of the cutter wheel is 145 ℃, the working thickness of the liquid film is 1.3mm; when the angle of the cutter wheel is 165 degrees, the working thickness of the liquid film is 2.5mm;
d: selecting a cutter wheel (the diameter is 6.22mm and the angle is 145 degrees), and when the pressure of the cutter wheel to the glass is 1Kp, the working thickness of the liquid film is 1.5mm; when the pressure of the cutter wheel to the glass is 3Kp, the working thickness of the liquid film is increased to 2.5mm;
e: selecting a toothless cutter wheel with a smooth outer edge, cutting common float glass with a thickness of 1.2mm, which is softer in material, and enabling the working thickness of a liquid film to be 1.8mm; selecting a cutter wheel with teeth (100-300 teeth) at the outer edge, and increasing the working thickness of a liquid film to 3.0mm when glass for TFTs and high-alumina glass for touch screens, which are made of harder materials, with the same thickness are cut;
in the examples a to e, the amount of liquid entering the liquid film from the head end of the liquid film and the amount of liquid leaving the tail end of the liquid film are increased and decreased according to the increase and decrease of the working thickness, and the wind pressure of the air curtain is also increased and decreased accordingly, so as to ensure that the liquid film 9 does not overflow out of the air curtain 14.
Since the liquid film 9 is oil-free, it is easily removed from the glass surface; the glass is hydrophilic, the fresh float glass is particularly hydrophilic, the liquid film is easy to infiltrate and spread on the surface of the glass, contact points are covered, scraps are easy to combine with water and not easy to separate, and the scraps are favorable for restraining the liquid film; the ethanol in the liquid film can also permeate the scribing cracks, so that the cracks extend to the depth of the glass plate, the breaking is facilitated, the ethanol can be mutually dissolved with the cutting oil, and the liquid film is facilitated to wrap glass scraps adhered with the cutting oil.
By controlling the liquid output of the coating head 6f, the liquid suction of the adsorption head 6c and the pressure of the air curtain blown by the air knife 16a, the liquid film is prevented from being spread and thinned to two sides, the impact damage of the moving knife wheel to the liquid film is overcome, the liquid film 9 is kept continuous and has a working width W and a working thickness H, the working width is smaller than the natural flattening width of the liquid film, the working thickness is larger than the natural flattening thickness of the liquid film, and the continuous, working width and the working thickness work together to ensure that the contact point 15 of the knife wheel and glass is always covered by the liquid film, and glass fragments generated by scribing are always restrained in the liquid film. The liquid with the scraps is finally sucked into the liquid return tank 4 by sucking the liquid with the same amount as the applied amount of the coating head from the tail end of the liquid film through the adsorption head, so that the scraps are removed from the glass surface.
The dash-dot arrows in fig. 1 are the directions in which the glass ribbon 10 moves on the glass delivery stage.
The dash-dot lines in fig. 4 and 5 are cut lines.
The solid origin on the stippled line in fig. 5 is the cutting point of the cutter wheel.
