Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting device for plastic processing. Background Art

[0002] The advantages of laser cutting of plastic sheets mainly include high precision, contactless processing, diversified design adaptability, waste reduction and environmental protection and pollution-free. The cutting path of laser cutting is narrow, and the cutting depth can be accurately controlled, the use of materials is optimized, the waste of raw materials is reduced, the material utilization rate is improved, and the economy is improved. In actual plastic processing work, laser cutting is usually used for cutting plastic products, but the current laser cutting devices for plastic processing usually use single-piece cutting. Batch cutting is prone to affect the cutting accuracy due to deformation, which is not convenient for batch stacking cutting, and the cutting efficiency is low. At the same time, it is not convenient to prevent plastic adhesion and easily increase the defective rate. The materials removed by traditional cutting methods are prone to thermal deformation and displacement, which affects the cutting accuracy. Directly pressing and positioning the plastic sheet is easy to block the cutting line, which is not convenient for positioning to prevent interference from the cutting head. At the same time, it is not convenient to test the cutting power in real time.

The separation process is carried out while the temperature at the cutting seam is high to avoid adhesion.

When the plastic is cut, the discharge slot 4031 can be driven to align with the bottom of the cutting position to undertake and test the cutting quality.

[0035] Embodiment 2, on the basis of embodiment 1, the pressing and positioning member 6 comprises: a pressing and positioning block 601, a positioning plug-in shaft 602, a positioning spring 6021, a thermal switch 603 and an electromagnet 604, two pressing and positioning blocks 601 are provided, and the two pressing and positioning blocks 601 are respectively located in the two guide grooves 3011; the shapes of the two pressing and positioning blocks 601 are respectively consistent with the two guide grooves 3011; four positioning plug-in shafts 602 are respectively slidably plugged into the two pressing and positioning blocks 601; the four positioning plug-in shafts 602 are respectively plugged into the guide grooves 3011; four positioning springs 6021 are respectively sleeved on the two pressing and positioning blocks 601, and the positioning springs 6021 are connected to the tail of the positioning plug-in shaft 602; the four positioning plug-in shafts on the pressing and positioning block 601 are respectively connected to the rear of the positioning plug-in shaft 602; The positions on both sides of 602 are respectively fixedly installed with thermal switches 603; four electromagnets 604 are fixedly installed on the two pressing and positioning blocks 601, and the four electromagnets 604 are respectively aligned with the positioning plug-in shaft 602; the eight electromagnets 604 are respectively electrically connected to the two thermal switches 603 on the same side; the anti-sticking test piece 7 includes: a lower pressing ring 701, a V-shaped spring piece 702, and the lower pressing ring 701 is slidably sleeved on the pressing and positioning block 601; a circle of V-shaped spring pieces 702 are fixedly installed on the lower pressing ring 701; the ends of a circle of V-shaped spring pieces 702 are respectively connected to the inner side of the pressing and positioning block 601; the anti-sticking test piece 7 also includes: a pressing switch 703, a pressing switch 703 is fixedly installed on the inner side of the pressing and positioning block 601, and the end of the pressing switch 703 is pressed and fitted to the pressing ring 701;The push-down switch 703 is electrically connected to the lamp bead on the prompt light 102. The pressing positioning piece 6 can be used to position and press the cutting area, which can improve the stability of the cutting area and avoid expansion due to thermal stress at the cutting seam, which affects the stability of the cutting area and displacement, thereby affecting the cutting quality. This structure can be pressed to position and avoid displacement. At the same time, this structure uses four positioning plug-in shafts 602, which can automatically retract after detecting the laser cutting head to avoid affecting the cutting process. The remaining three positioning plug-in shafts 602 also ensure stable positioning. The use of the anti-sticking test piece 7 can facilitate the seam adhesion detection in the cutting area to avoid the plastic sheet after cutting from falling as a whole. Only partial falling or no falling at all will affect the separation and promotion work of the separation blade strip 4032, and even the separation blade strip 4032 will cause damage to the plastic sheet. Injury can improve the safety of this structure, and also reflect the power of the laser cutting machine to avoid the problem of not cutting through. The shape and size of the pressing and positioning block 601 can be adjusted according to the production needs. When the laser cutting machine cuts outside the pressing and positioning block 601, the cutting position has high heat, which can be detected by the thermal switch 603, and the electromagnet 604 is controlled to pass the electromagnetic suction positioning plug shaft 602, and the positioning plug shaft 602 can be pulled out from the guide groove 3011 to release the positioning. The other three positioning plug shafts 602 are similar, and can automatically retract when the cutting head passes. During the process, the pressing and positioning block 601 is kept pressed on the plastic sheet for positioning in real time. If the cutting area is cut through, it can be squeezed down by the V-shaped spring 702. At this time, the lower pressing ring 701 will also move down, and the lower pressing switch 703 will no longer be squeezed, so that the control prompt light 102 can be turned on to prompt. ;

[0036] The working principle of this embodiment is as follows: first, by placing the plastic sheet on the plastic limit frame 201, four laser cutting machine seats 103 are used to install the laser cutting machine through bolts, the connecting bolts 302 are threadedly connected to the plastic limit frame 201, and the plastic sheet is pressed into position by the limit pressure plate 301. At this time, the laser cutting machine can be used for laser cutting. When the plastic is cut, the discharge slot 4031 can be driven to align below the cutting position to carry out the connection and test the cutting quality. Once the cutting temperature exceeds the standard, the high-temperature molten droplets will drip on the discharge slot 4031. At this time, the driving roller set by the driving motor 402 is driven 401 drives the conveyor belt 403 to move, and the discharge slot 4031 can drive the molten droplets to move, squeezing the extrusion arc noodle 502 set. At this time, the clamping V-shaped piece 503 is compressed, and the micro switch 504 is also squeezed, and the lamp bead on the control prompt light 102 lights up to prompt. During normal cutting work, the conveyor belt 403 is supported on the bottom support of the plastic sheet. After the cutting area of ​​the plastic sheet is cut off, the discharge slot 4031 is controlled to move to the bottom of the cutting area to receive it. Under the action of gravity, it naturally falls into the discharge slot 4031. The depth of the discharge slot 4031 is the thickness of a plastic sheet. At this time, when the discharge slot 4031 moves The conveyor belt 403 also drives the separation blade strip 4032 to move, and the separation blade strip 4032 is used to separate the plastic sheets, and it is convenient to push out the plastic sheets by the separation blade strip 4032. In real time, only the bottom plastic sheet can be pushed out to achieve the separation of the single sheet. When the laser cutting machine presses the outer side of the positioning block 601 for cutting, the heat at the cutting position is high, which can be detected by the thermal switch 603, and the electromagnet 604 is controlled to pass the electromagnetic suction positioning plug-in shaft 602, and the positioning plug-in shaft 602 can be drawn out from the guide groove 3011 to release the positioning. The other three positioning plug-in shafts 602 are similar, and they can be automatically moved when the cutting head passes by. The pressing block 601 is pressed on the plastic sheet to position it. After the cutting is completed, the discharge slot 4031 is driven to move below the cutting area. If adhesion occurs in the cutting area at this time, the pressing ring 701 cannot press down the plastic sheet as a whole under the pressure of the V-shaped spring piece 702. At this time, the pressing switch 703 will continue to be squeezed by the pressing ring 701, indicating that adhesion occurs or the cutting is not through. On the contrary, if the cutting area is cut through, it can be squeezed down by the V-shaped spring piece 702. At this time, the pressing ring 701 will also move down, and the pressing switch 703 will no longer be squeezed, so that the control prompt light 102 can be turned on to prompt.
