Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, and in particular relates to a laser tube cutting machine for processing plastic hoses. Background Technology

[0002] A laser pipe cutting machine is a device that uses the high energy density of a laser beam to cut pipes. It is widely used in the processing of various pipes such as metal, plastic, and rubber, and features high precision, high efficiency, and flexibility. For example, the laser cutting method for beveling plastic pipes proposed in patent publication number CN115740784B.

[0003] When using a laser tube cutter to cut thin plastic hoses, the thin plastic has a low melting point, and the laser energy can easily cause it to overheat, resulting in local softening or shrinkage. This can lead to bending, twisting, or changes in the diameter of the hose. As a result, after the plastic hose is cut, the shrinking and deformed ends need to be trimmed, which undoubtedly increases the workload of the operator.

[0004] To address this issue, a laser tube cutting machine for processing plastic hoses is proposed. Summary of the Invention

[0016] Compared with existing technologies, the advantages of a laser tube cutting machine for processing plastic hoses are:

[0017] 1. By using the negative pressure and inflation components, when cutting thin plastic hoses with a laser cutting machine, the system can support the plastic hose from the inside and automatically absorb the cut edge of the plastic hose, thus preventing the cut edge from twisting and deforming due to excessive heat after laser cutting and ensuring the cutting quality of thin plastic hoses.

[0018] 2. By using the pre-treatment components, the cut area of ​​the plastic hose can be frozen during cutting, which increases the hardness and brittleness of the plastic hose and reduces its flexibility. This reduces the heat conduction range during laser cutting and avoids problems such as local softening, shrinkage or melting collapse caused by heat diffusion to the surrounding area. It effectively inhibits hose bending, twisting or diameter deformation.

[0019] 3. By using the exhaust gas treatment box and air pump, the harmful gases generated during the cutting of the plastic hose can be adsorbed and treated, thereby reducing the impact of harmful gases on the surrounding environment. Attached Figure Description

A positioning sleeve 52 is fixedly connected to the side wall of the mounting plate 7 through a bracket, which facilitates the recycling of the winding tube 18.

[0035] The operating principle of this invention is explained as follows: The plastic hose to be cut is fitted inside the ceramic cylinder 8, with a gap of 0.1mm between the ceramic cylinder 8 and the plastic hose. Then, the operator sends an electrical signal to the control cabinet 2 via the control panel on the surface of the control cabinet 2. Upon receiving the signal, the control cabinet 2 controls the left-side limit electric push rod 13 to operate, causing the left-side limit block 14 to contact the inner wall of the ceramic cylinder 8. Next, the control cabinet 2 controls the moving end of the drive electric push rod 112 to operate, causing the moving end of the drive electric push rod 112 to move the second cylinder 12 to the right to the set position. Then, control cabinet 2 controls the right-side limit electric push rod 13 to operate, causing the right-side limit electric push rod 13 to drive the right-side limit block 14 to contact the inner wall of the ceramic cylinder 8. Simultaneously, control cabinet 2 controls the left-side limit electric push rod 13 to drive the left-side limit block 14 to move downwards. Next, control cabinet 2 controls the drive electric push rod 112 to retract. Since the second cylinder 12 is relatively fixed at this time through contact with the inner wall of the ceramic cylinder 8 via the right-side limit block 14, when the drive electric push rod 112 retracts, the first cylinder 111 will move to the right, and the first cylinder 111 will pull the right end of the take-up tube 18 to move together. The take-up motor 20 is... For non-clamping motors, when the right end of the take-up tube 18 moves to the right, the take-up drum 21 will rotate at a certain angle. Repeating the above steps will move the negative pressure component 11 to the first cutting area of ​​the plastic hose (the laser tube cutter will cut multiple parts of the plastic hose). Then, the control cabinet 2 controls the second lead screw linear module 10 to drive the pretreatment component 37 to move to the left. At the same time, the control cabinet 2 will also control the dust removal electric push rod 45 to work, using the dust removal electric push rod 45 to drive the suction head 46 to move towards the hose to the set position, so that the bristles 47 contact the surface of the hose. Then, the control cabinet 2 controls the annular slide rail mechanism to work (annular... The slide rail mechanism consists of a drive motor, a ring cabinet, a sliding seat, gears, and a gear ring. The drive motor drives the gears to rotate, and through the meshing of the gears and the gear ring, the vertical plate 43 can be moved. The vertical plate 43 moves the vertical plate 43, which in turn drives the dust collection box 44 and the brush 47 to rotate along the hose. At the same time, the control cabinet 2 also controls the dust pump 49 to work. The brush 47 can sweep off the dust attached to the surface of the hose. The dust pump 49 extracts the air inside the dust collection box 44, reducing the air pressure inside the dust collection box 44. The external air will carry the dust through the suction head 46 and the telescopic tube 48 into the dust collection box 44 and store it.

[0036] Once the pretreatment component 37 moves to the first cutting area, the control cabinet 2 controls the semiconductor cooling plate 38 and the air pump 39 to operate simultaneously. The air pump 39 delivers external gas to the cooling chamber 372, where it is cooled by the semiconductor cooling plate 38. The cooled gas is then transported through the vertical pipe 40 to the ring pipe 41 and sprayed through the nozzle 42 onto the cutting area of ​​the plastic hose, cooling the cutting area. After ten seconds of cooling operation, the control cabinet 2 controls the pretreatment component 37 to move to the next cutting area for cooling. Cabinet 2 also controls the laser cutting head 6 and the air pump 23 to work simultaneously. As the negative pressure component 11 moves, it drives the air cylinder 261 and the air pipe 262 to move relative to each other. When the air pipe 262 moves relatively to the right within the air cylinder 261, it drives the piston ring 27 to move to the right as well, reducing the air pressure on the left side of the piston ring 27. External gas then enters the air cylinder 261 through the inlet pipe 30 and the second one-way valve 31. When the air pipe 262 moves relatively to the left within the air cylinder 261, it drives the piston ring 261 to move to the right as well. 7. The gas on the left side is squeezed, allowing it to enter the first cylinder 111 and the second cylinder 12 through the air supply pipe 28, the air filling pipe 262, and the two first one-way valves 29. The gas is discharged into the rubber ring 34 through the air pressure hole 35, increasing the internal air pressure of the rubber ring 34. The rubber ring 34 will inflate and expand. This process is repeated, and the rubber ring 34 will gradually expand. When the rubber ring 34 comes into contact with the inside of the ceramic cylinder 8, the internal air pressure of the rubber ring 34 will continue to increase. The control cabinet 2 detects that the internal air pressure of the rubber ring 34 has reached the set threshold (0). After reaching 0.05 standard atmospheres, the control valve 33 will open, allowing the air cylinder 261 to connect with the outside through the vent pipe 32. When the piston ring 27 moves to the left, the gas will be discharged through the vent pipe 32, preventing the rubber ring 34 from continuing to inflate. Subsequently, the exhaust valve 55 can be opened to allow the gas inside the rubber ring 34 to be discharged through the exhaust pipe 54. Furthermore, the friction between the rubber ring 34 and the inner wall of the ceramic cylinder 8 is less than the friction between the limit block 14 and the ceramic cylinder 8, so the expanded rubber ring 34 will not hinder the movement of the negative pressure component 11.

[0037] When the laser cutting head 6 cuts the plastic hose, the vacuum pump 23 extracts the gas from inside the take-up drum 21. Simultaneously, the gas inside the first cylinder 111 and the second cylinder 12 is extracted through the suction port 17 and the take-up tube 18, creating a negative pressure state between the first cylinder 111 and the second cylinder 12 (the area between the first cylinder 111 and the second cylinder 12 is the cutting area of ​​the plastic hose). Through the negative pressure port 9 between the first cylinder 111 and the second cylinder 12, the plastic hose in the cutting area can be adsorbed. When the negative pressure value between the first cylinder 111 and the second cylinder 12 reaches a set threshold (0.5 standard atmospheres), external gas enters the first cylinder through the pressure tube 24 and the pressure valve 25. Between 111 and the second cylinder 12, during the cutting process of the plastic hose by the laser cutting head 6, the plastic hose can be made to stick tightly to the surface of the ceramic cylinder 8. After being frozen by the pretreatment component 37, the hardness and brittleness of the plastic hose increase and the flexibility decreases, thereby reducing the heat conduction range during laser cutting and avoiding the problem of local softening, shrinkage or melting collapse caused by heat diffusion to the surrounding area. Furthermore, the negative pressure is used to make the cut of the plastic hose stick tightly to the ceramic cylinder 8, further avoiding the problem of deformation and bending at the cut, ensuring the cutting quality of the plastic hose. Moreover, the harmful gases generated during cutting are transported to the exhaust gas treatment box 53 by the exhaust pump 23 for treatment, and the activated carbon inside the exhaust gas treatment box 53 is used to adsorb the harmful gases.

[0038] After the plastic hose is cut for the first time, the control cabinet 2 will control the winding motor 20 to work. The winding motor 20 will drive the winding drum 21 to rotate. The winding drum 21 will pull the winding tube 18, and the winding tube 18 will drive the negative pressure component 11 to move to the next cutting area.
