Description

Technical Field

[0001] The invention relates to the technical field of tarpaulin processing, and in particular to an automatic laser cutting device for tarpaulin processing. Background Art

[0002] In modern industry and daily life, tarpaulins, as an important material, are widely used in logistics, outdoor advertising, construction and other fields. With the continuous advancement of technology, the types of tarpaulins are becoming more and more abundant, especially composite tarpaulins, which have been favored by the market due to their excellent properties, such as high strength, waterproof and fireproof.

[0003] However, there are many technical difficulties in the current tarpaulin processing, especially in the cutting of composite tarpaulins. For composite tarpaulins, since they are composed of multiple layers of different materials, the traditional cutting method mostly uses a single laser head for cutting. However, when using a single laser head for cutting, it often causes undesirable phenomena such as burning, deformation or discoloration at the cutting point, which seriously affects the quality and appearance of the tarpaulin.

[0004] In addition, static electricity is easily accumulated during the production, transportation and storage of tarpaulins. During the cutting process, static electricity will cause the debris generated by cutting to be adsorbed on the surface of the tarpaulin, which not only affects the cleanliness and aesthetics of the tarpaulin, but may also affect the subsequent performance. For example, in logistics transportation, the debris adsorbed by static electricity may reduce the waterproof performance of the tarpaulin and increase the risk of damage to the goods. At the same time, static electricity may also cause safety hazards. For example, static electricity sparks may cause dangerous situations such as fire or explosion;

[0005] Therefore, it is necessary to design an automated laser cutting device for tarpaulin processing to solve the above problems. Summary of the invention

After each cutting is completed, the material can be unloaded automatically and the new tarpaulin can be moved to the cutting area of ​​the workbench.

A negative pressure plate 44 is slidably connected in the adsorption box 14, and the adjacent sides of the negative pressure plate 44 and the electromagnet 43 are elastically connected by a first spring 19. A plurality of negative pressure holes are provided on the inner bottom of the adsorption box 14, and a second motor 16 is installed on the front side of the fixed frame 15. The output shaft of the second motor 16 is at the end The end is fixedly connected to the threaded rod 24, and the rear side of the threaded rod 24 extends to the outside. A fixed plate is fixedly connected to the right side of the workbench 1, and a short rod 21 that is rotatably connected passes through the fixed plate. The short rod 21 and the second screw rod 17 located on the front side are both provided with mutually meshing bevel gears 20. The short rod 21 and the threaded rod 24 are transmission-connected through a second transmission assembly 22. The second transmission assembly 22 includes a second sprocket wheel arranged on the short rod 21 and the threaded rod 24. The two second sprocket wheels are transmission-connected through a second chain. A one-way bearing is provided between the second screw rod 17 and the corresponding bevel gear 20. When the threaded rod 24 rotates clockwise, the second screw rod 17 will not be driven to rotate through the two bevel gears 20. When the threaded rod 24 rotates counterclockwise, the second screw rod 17 can be driven to rotate through the two bevel gears 20. The threaded layer on the second screw rod 17 is a reciprocating threaded layer.

[0033] The static elimination component includes two vertical plates 4 fixedly connected to the workbench 1, the adjacent sides of the two vertical plates 4 are fixedly connected with a cross bar, a hollow plate 5 is arranged between the two vertical plates 4, two cross bars penetrate the hollow plate 5, a plurality of atomizing nozzles 7 are installed at the lower end of the hollow plate 5, the adjacent sides of the hollow plate 5 and the slider 9 are fixedly connected with a rectangular rod, a reciprocating box 12 is installed on the fixed block at the rear side, the rear side of the first screw rod 8 extends into the reciprocating box 12 and is fixedly connected with a cam 25, and the reciprocating box 12 is sealed.

The left space of the reciprocating box 12 is connected to the hollow plate 5 through a hose 28. The left space of the reciprocating box 12 is connected with a liquid inlet pipe 29. Both the liquid inlet pipe 29 and the hose 28 are provided with a one-way valve. An external water tank is required to connect the liquid inlet pipe 29 with the inner bottom of the water tank. The water in the water tank enters the reciprocating box 12 in one direction through the liquid inlet pipe 29, and the water in the reciprocating box 12 enters the hollow plate 5 in one direction through the hose 28.

[0034] The functional principle of the present invention can be explained through the following operation mode: when cutting the tarpaulin, the tarpaulin is wound on the winding roller 2, and one end of the tarpaulin is pulled so that the one end of the tarpaulin passes under the two pressing rollers 3 and then moves to the bottom of the laser cutting head 38 and enters into the two U-shaped blocks 13. The staff controls the two second pneumatic rods 39 to stretch so that the corresponding two clamping plates 40 move relatively to clamp one end of the tarpaulin;

[0035] Then the staff controls the output shaft of the second motor 16 to rotate forward and reverse once. When the output shaft of the second motor 16 rotates forward and reverse, the threaded rod 24 will be driven to rotate forward and reverse, so that the connection block drives the adsorption box 14 to move forward and backward once. When the threaded rod 24 rotates forward, the short rod 21 is driven to rotate forward through the second transmission assembly 22, and the short rod 21 drives the two bevel gears 20 to rotate. Due to the setting of the one-way bearing, the rotation of the bevel gear 20 will not drive the second screw rod 17 to rotate at this time. When the threaded rod 24 reverses, the short rod 21 will be driven to reverse, and the second screw rod 17 located at the front side will be driven to rotate through the two bevel gears 20. Since the two second screw rods 17 are connected by the first transmission assembly 18, the two second screw rods 17 rotate synchronously.

[0036] The rotation of the two second screw rods 17 drives the rectangular block and the U-shaped block 13 to rotate, pulling the tarpaulin to the right (the tarpaulin in the initial state is longer and is wound on the winding roller 2. Pulling one end of the tarpaulin to the right will cause the winding roller 2 to rotate);

[0037] Before processing, the staff sets the parameters of each laser cutting head 38 through the controller according to the properties of each material layer of the tarpaulin, so that during the cutting process, each laser cutting head 38 will only cut the corresponding material layer. After one end of the tarpaulin is pulled to the specified position on the workbench 1, the multiple second pneumatic rods 39 are controlled to shrink to release the clamping of one end of the tarpaulin. The staff controls the first motor 6 to run and drive the first screw 8 to rotate, so that the slider 9 drives the multiple laser cutting heads 38 to move forward and backward. During the movement of the slider 9, the front and rear sides of the slider 9 will touch the counting sensor. Each time the slider 9 touches the counting sensor, it will transmit a signal to the controller. The controller controls the first pneumatic rod 33 to shrink a certain distance (the shrinkage distance of the first pneumatic rod 33 is the same each time), so that the moving block 32 drives the rack 34 to move right. The rack 34 moves right and drives the vertical rod 31 to rotate through the gear, and then drives the disc 35 to rotate sixty degrees, so that the multiple laser cutting heads 38 are used in turn to cut each material layer of the tarpaulin separately.

[0038] It is worth mentioning that a positioning sensing block 37 is provided at the lower end of the slider 9. When the positioning sensor 36 rotates to the bottom of the positioning sensing block 37, the electrical signal generated by the positioning sensor 36 is transmitted to the controller, and the controller controls the corresponding laser cutting head 38 to work;

[0039] When the electric signal transmitted from the counting sensor to the controller reaches a certain number of times, the controller controls the multiple laser cutting heads 38 and the first motor 6 to stop working, and controls the first pneumatic rod 33 to reset, controls the electromagnet 43 to be energized for a period of time, and controls the second motor 16 to rotate forward and reverse twice. After the electromagnet 43 is energized, it generates an attractive force on the negative pressure plate 44, and the negative pressure plate 44 moves upward, so that the bottom space of the adsorption box 14 is increased and the air pressure is reduced, so that the outside gas enters the adsorption box 14. Since the adsorption box 14 is close to the cut tarpaulin, the tarpaulin will be adsorbed on the lower end of the adsorption box 14;

[0040] After the second motor 16 is running, the suction box 14 will be moved forward first, driving the cut tarpaulin to move forward, and then the cut tarpaulin will be removed from the workbench 1. When the suction box 14 moves to the front, the electromagnet 43 is powered off, and the negative pressure plate 44 moves back under the elastic action of the first spring 19, and the tarpaulin and the suction box 14 are separated.

[0041] During the two positive and negative rotations of the output shaft of the second motor 16, the two U-shaped blocks 13 will first move left and then right (when the two U-shaped blocks 13 move left, the cut tarpaulin has been removed from the workbench 1). When the two U-shaped blocks 13 move left to the limit distance, the pressure block 41 will squeeze the pressure sensor 42. The pressure sensor 42 generates an electrical signal and transmits it to the controller. The controller controls the multiple second pneumatic rods 39 to stretch again. Since the edge of the cut tarpaulin exceeds the right side of the cover plate 23, the multiple second pneumatic rods 39 can be stretched to clamp the edge of the tarpaulin and then pull it to the right, thereby automatically loading and unloading the tarpaulin.

[0042] During the tarpaulin cutting process, the rotation of the first screw rod 8 drives the cam 25 to rotate. When cutting, the liquid inlet pipe 29 is placed in the water tank. Since the piston 26 is tightly fitted with the cam 25, the piston 26 moves left and right under the elastic action of the second spring 27. The rightward movement of the piston 26 increases the left side space of the reciprocating box 12 and reduces the air pressure, thereby allowing the water in the water tank to enter the reciprocating box 12. When the piston 26 moves to the left, the left side space of the reciprocating box 12 decreases, the air pressure increases, and the water is pressed into the hollow plate 5. Then, a plurality of atomizing nozzles 7 are used to form water mist and spray it on the tarpaulin to remove static electricity from the tarpaulin.

[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
