Description

Technical Field

[0001] The invention relates to the technical field of tempered glass cutting, in particular to a multi-stage cutting device applied to tempered glass and an operating method thereof. Background Art

[0002] Tempered glass is a type of safety glass. In fact, tempered glass is a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc.

[0003] Announcement No. CN216328673U discloses a cutting device for tempered glass processing. When using the device, the device is first started, one end of the tempered glass is placed on the L-shaped fixed plate, and the motor is started. The motor drives the screw rod to rotate. Since the internal thread groove of the moving part is arranged, the thread groove and the screw rod are meshed, so that the moving part is driven to move horizontally through the rotation of the screw rod. Then, the upper L-shaped fixed plate is driven to move toward the center of the screw rod through the moving part to squeeze and fix the tempered glass. When using the device, the negative pressure pump can be started to generate negative pressure, so that an adsorption force is generated in the collection tank. Then, when the device is working, the waste residue generated by cutting will fall into the second leakage net through the first leakage net. At this time, the negative pressure generated by the negative pressure pump will suck the waste residue remaining on the first leakage net and the second leakage net into the collection tank and store it through the collection bin. When the device stops working, the waste residue can be processed by extracting the collection bin. However, the above patent still has the following problems in actual use:

[0004] Although the cutting device for tempered glass processing can fix the tempered glass, it is not convenient to take the tempered glass after the tempered glass is cut. Since the bottom of the tempered glass is flat and heavy, it will fit with the L-shaped fixing plate when placed on the workbench, causing the bottom of the tempered glass to be suspended in the air, which is easy to cause uneven force and breakage during cutting, which is not conducive to the integrity of the tempered glass cutting.

[0005] Therefore, a multi-stage cutting device for tempered glass and an operating method thereof are proposed to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a multi-stage cutting device for tempered glass and an operating method thereof, so as to solve the problem that although the cutting device for tempered glass processing proposed in the above-mentioned background technology can fix the tempered glass, it is not convenient to take the tempered glass after the tempered glass is cut.

[0029] 1. By setting the tempered glass fixing mechanism, not only can the debris collection box at the bottom of the cutting table be used to collect the debris generated by glass cutting, but also the glass to be cut can be placed on the ejector plate, and the gravity of the glass itself and the downward pressure of the top pressing cutting mechanism can be used to make the ejector plate drive the vertical limit block and the vertical rack to descend, and the meshing connection between the vertical rack, the meshing gear and the horizontal rack can be used to make the horizontal rack drive the horizontal limit block and the clamping bracket to move relatively, and the clamping plate can be used to clamp and fix the two sides of the glass, and at the same time the glass drops to the top of the fixed support block, and the combined effect of the fixed support block and the ejector plate can be used to improve the stability of the glass during cutting, and the adjusting bolt can be driven to rotate by turning the adjusting knob to make the two clamping plates move relatively, and the distance between the two clamping plates can be adjusted to adapt to glass of different sizes, and after the cutting is completed, the elastic force of the ejector spring can be used to lift the cut glass, so as to facilitate the picking and placement of the glass;

The lifting motor 204 is used to drive the sprocket transmission assembly 205 and the lifting threaded rod 206 to rotate, so that the lifting threaded sleeve 207 drives the lifting plate 208 to move up and down, and the second connecting spring 219 and the clamping frame 220 at the bottom of the dust cover 216 are used to perform preliminary clamping on the top of the glass.

[0047] The bottom of the lifting plate 208 is rotatably connected to a first rotating support 211, the bottom of the first rotating support 211 is rotatably connected to a first pressing rotating rod 212, the bottom of the first pressing rotating rod 212 is rotatably connected to a second rotating support 213, a pressing plate 214 is fixedly installed at the bottom of the second rotating support 213, a second pressing rotating rod 215 is rotatably connected to one side of the middle of the first pressing rotating rod 212, the end of the second pressing rotating rod 215 is rotatably connected to a dust cover 216, and dust suction ports 217 are symmetrically opened on both sides of the middle of the dust cover 216 A first connecting spring 218 is fixedly installed around the top of the dust cover 216, a second connecting spring 219 is fixedly installed around the bottom of the dust suction port 217, and a clamping frame 220 is fixedly installed at the bottom of the second connecting spring 219, which continues to press the glass downward to move the glass to the top of the fixed support block 105. At the same time, under the action of the second clamping rotating rod 215, the first clamping rotating rod 212 can be rotated, and the surface of the glass is compressed for the second time through the clamping plate 214, thereby further improving the stability of the glass and facilitating the cutting of the glass.

[0048] A translation motor 221 is fixedly installed on one side of the dust cover 216, and a translation threaded rod 222 is fixedly connected to the output end of the translation motor 221. The outer side of the translation threaded rod 222 is threadedly connected to a translation threaded sleeve 223. The translation threaded sleeve 223 is limited and slidably connected to the dust cover 216. A mounting sleeve 224 is fixedly installed on the bottom of the translation threaded sleeve 223.

After the tempered glass is formed, the compressive stress and tensile stress inside and outside the tempered glass have reached a balance. This balanced state makes the tempered glass have strong bending resistance and impact resistance. If the tempered glass is cut, the balance of its compressive stress will be destroyed, causing the glass to break. Therefore, by horizontally rotating the cutting device 230, the two mounting limit blocks 229 of the mounting rod 228 pass over the limit spring 226 and the limit protrusion 227, the mounting rod 228 and the cutting device 230 can be taken out from the inside of the mounting sleeve 224, and the laser cutting equipment is replaced to cut the tempered glass using laser cutting technology.

[0049] A dust box 233 is fixedly installed on the top of the lifting top plate 202, and a mounting thread block 234 is threadedly connected to the inner side of the top of the dust box 233, and a fan cover 235 is fixedly installed on the top of the mounting thread block 234.

Dust collecting pipes 241 are symmetrically installed on both sides of the bottom of 233, and the ends of the dust collecting pipes 241 are fixedly connected with serpentine elbows 242. The serpentine elbows 242 are fixedly connected to the dust hood 216 through the dust suction port 217. When ordinary untempered glass is cut, a certain amount of dust and debris will be generated. The dust collecting fan 236 is started, and the dust generated by the cutting is sucked into the interior of the dust collecting box 233 through the serpentine elbows 242 and the dust collecting pipes 241 by exhausting air. The dust can be filtered and collected by using the filter inserts 239 and the staggered filter screens 240, thereby improving the dust absorption effect.

[0050] Working principle: Before using this multi-stage cutting device for tempered glass and its operating method, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig.11 As shown, first, the glass to be cut is placed on the ejector plate 108, and the lifting motor 204 is used to drive the sprocket transmission assembly 205 and the lifting threaded rod 206 to rotate, so that the lifting threaded sleeve 207 drives the lifting plate 208 to move up and down, and the second connecting spring 219 and the clamping frame 220 at the bottom of the dust cover 216 are used to preliminarily clamp the top of the glass, and the gravity of the glass itself and the downward pressure of the top clamping and cutting mechanism 2 are used to make the ejector plate 108 drive the vertical limit block 109 and the vertical rack 110 to descend, and the meshing connection between the vertical rack 110, the meshing gear 111 and the horizontal rack 112 is used to make the horizontal rack 112 drive the horizontal limit block 113 and the clamping bracket 114 to move relative to each other, and the clamping plate 118 can be used to clamp and fix both sides of the glass, and at the same time, the glass descends to the top of the fixed support block 105, and the fixed support block 105 and the ejector plate 108 work together to improve the stability of the glass during cutting.

[0051] Secondly, at the same time, under the action of the second pressing rotating rod 215, the first pressing rotating rod 212 can be rotated, and the surface of the glass is pressed for the second time by the pressing plate 214, so as to further improve the stability of the glass and facilitate the cutting of the glass. The translation motor 221 is started to drive the translation threaded rod 222 to rotate, so that the translation threaded sleeve 223 drives the cutting device 230 to move, so as to realize the cutting of the glass. After the tempered glass is formed, the compressive stress and tensile stress inside and outside the tempered glass have reached a balance. This balance state makes the tempered glass have strong bending resistance and impact resistance. If the tempered glass is cut, the balance of its compressive stress will be destroyed, resulting in the glass breaking. Therefore, by horizontally rotating the cutting device 230, the two installation limit blocks 229 of the installation rod 228 pass over the limit spring 226 and the limit protrusion 227, the installation rod 228 and the cutting device 230 can be taken out from the inside of the installation sleeve 224, and the laser cutting device is replaced to cut the tempered glass using laser cutting technology.

[0052] Finally, when ordinary untempered glass is cut, a certain amount of dust and debris will be generated. The dust collecting fan 236 is started, and the dust generated by the cutting is sucked into the dust collecting box 233 through the serpentine bend 242 and the dust collecting pipe 241 by exhaust.

5. An operating method of a multi-stage cutting device for tempered glass, using the multi-stage cutting device for tempered glass as claimed in claim 4, the operating method steps are as follows: Step 1: Place the glass to be cut on the ejector plate (108), use the lifting motor (204) to drive the sprocket drive assembly (205) and the lifting threaded rod (206) to rotate, so that the lifting threaded sleeve (207) and the lifting sliding sleeve (209) drive the lifting plate (208) to move up and down, use the second connecting spring (219) and the pressing frame (220) at the bottom of the dust cover (216) to initially press the top of the glass, and use the gravity of the glass itself and the downward pressure of the top pressing and cutting mechanism (2) to drive the ejector plate (108) to move up and down. The vertical limit block (109) and the vertical rack (110) are lowered, and the meshing connection between the vertical rack (110), the meshing gear (111) and the horizontal rack (112) is utilized to enable the horizontal rack (112) to drive the horizontal limit block (113) and the clamping bracket (114) to move relative to each other, so that the clamping plate (118) can be used to clamp and fix both sides of the glass. At the same time, the glass is lowered to the top of the fixed support block (105), and the combined action of the fixed support block (105) and the ejection plate (108) is utilized to improve the stability of the glass during cutting; Step 2: Continue to press the glass downward to move the glass to the top of the fixed support block (105). At the same time, under the action of the second pressing rotating rod (215), the first pressing rotating rod (212) can be rotated, and the surface of the glass is pressed twice by the pressing plate (214), thereby further improving the stability of the glass and facilitating the cutting of the glass. The translation motor (221) is started to drive the translation threaded rod (222) to rotate, so that the translation threaded sleeve (223) drives the cutting device (230) to move, thereby achieving the cutting of the glass. After the tempered glass is formed, the pressure inside and outside the tempered glass is The compressive stress and the tensile stress have reached a balance. This balance makes the tempered glass have strong bending resistance and impact resistance. If the tempered glass is cut, the balance of its compressive stress will be destroyed, resulting in the glass breaking. Therefore, by horizontally rotating the cutting device (230), the two installation limit blocks (229) of the installation rod (228) pass over the limit spring (226) and the limit protrusion (227), the installation rod (228) and the cutting device (230) can be removed from the inside of the installation sleeve (224), and the laser cutting device is replaced to cut the tempered glass using laser cutting technology; Step 3: When cutting ordinary untempered glass, a certain amount of dust and debris will be generated. The dust collecting fan (236) is started to draw the dust generated by the cutting through the serpentine curved pipe (242) and the dust collecting pipe (241) into the dust collecting box (233) by means of exhaust. The filter insert (239) and the staggered filter screen (240) can be used to filter and collect the dust, thereby improving the dust absorption effect. The debris collection box (103) at the bottom of the cutting table (101) is used to collect the debris generated by the glass cutting. After the cutting is completed, the elastic force of the ejection spring (107) can be used to lift up the cut glass, so as to facilitate the glass to be taken and placed.
