Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a welding machine used in the production of geocells. Background Technology

[0002] Geocells are three-dimensional, mesh-like cell spaces made of polymer sheets, formed through various processes. They are flexible, collapsible for transport, and unfolded and filled with soil or concrete when needed, creating structures with strong lateral confinement and high rigidity. They are widely used in engineering fields such as reinforcing railway and highway subgrades, protecting airport and port slopes, and constructing retaining walls. Generally, geocells are made of polymer sheets and welded together using ultrasonic welding equipment.

The mounting grooves 45 are located between the adsorption grooves 44 on both sides. An ultrasonic welding head 46 is fixedly provided inside each mounting groove 45. The output end of the ultrasonic welding head 46 is flush with the bottom surface of the pressing plate 42. A third sheet 10 can be provided at the bottom of the pressing plate 42.

[0033] Mounting plates 21 are respectively provided on both sides of the mounting box 2 near the bottom plate 1. Each mounting plate 21 is provided with two drive rollers 22. The two drive rollers 22 are arranged vertically on the same vertical line. A second sheet 8 is arranged between the two drive rollers 22. The same second sheet 8 is arranged between the two drive rollers 22. The drive rollers 22 are electrically connected to the mounting box 2. The mounting box 2 can control the upper and lower drive rollers 22 to rotate in opposite directions, thereby moving the second sheet 8 between them electrically. The direction of movement of the second sheet 8 is the same as the transport direction of the bottom conveyor belt 12. A feeding structure 5 is provided between the two mounting plates 21. The first rotating roller 51 and the second rotating roller 52 of the feeding structure 5 are rotatably arranged between the two mounting plates 21. The first rotating roller 51 and the second rotating roller 52 are located near the bottom of the mounting plate 21. A plurality of first pads 7 are provided inside the mounting box 2. One end of the plurality of first pads 7 extends out of the mounting box 2 and extends into the space between the first rotating roller 51 and the second rotating roller 52. Both ends of the first rotating roller 51 and the second rotating roller 52 are provided with transmission gears 511. The third rotating roller 53 and the fourth rotating roller 54 of the feeding structure 5 are rotatably arranged between the two mounting plates 21. The third rotating roller 53 and the fourth rotating roller 54 are arranged above the first rotating roller 51 and the second rotating roller 52. A number of second pads 9 are arranged inside the mounting box 2. One end of the second pads 9 extends out of the mounting box 2 and extends into the space between the third rotating roller 53 and the fourth rotating roller 54. Both ends of the third rotating roller 53 and the fourth rotating roller 54 are provided with transmission gears 511.

[0034] A first transmission chain 55 and a first driven chain 56 are respectively arranged between the transmission gears 511 on both sides of the first rotating roller 51 and the third rotating roller 53. A first motor 59 is arranged on the mounting plate 21 near the first transmission chain 55. A drive gear 512 is arranged at the output end of the first motor 59. The drive gear 512 is arranged between the first transmission chains 55, and the tooth surface of the drive gear 512 meshes with the first transmission chain 55. A second transmission chain 57 and a second driven chain 58 are respectively arranged between the transmission gears 511 on both sides of the second rotating roller 52 and the fourth rotating roller 54. A second motor 510 is arranged on the mounting plate 21 near the second transmission chain 57. A drive gear 512 is arranged at the output end of the second motor 510. The drive gear 512 is arranged between the second transmission chains 57, and the tooth surface of the drive gear 512 meshes with the second transmission chain 57.

[0035] The first motor 59 and the second motor 510 are respectively mounted on the mounting plates 21 on both sides. The first rotating roller 51 and the third rotating roller 53 are connected to the first transmission chain 55 and the first driven chain 56 via a transmission gear 511. The second rotating roller 52 and the fourth rotating roller 54 pass through the inside of the first transmission chain 55 and the first driven chain 56. Similarly, the first rotating roller 51 and the third rotating roller 53 pass through the inside of the second transmission chain 57 and the second driven chain 58. The first transmission chain 55 and the second driven chain 58 are located on the same side, with the first transmission chain 55 being closer to the mounting plate 21. The second transmission chain 57 and the second driven chain 58 are located on the same side, with the second transmission chain 57 being closer to the mounting plate 21, so that the first motor 59 and the second motor 510 can mesh with the corresponding transmission chains. The first pad 7 and the second pad 9 are staggered along the horizontal plane, so that the pads and the sheet can be welded evenly during the welding process. At the same time, after the second pad 9 and the second sheet 8 are cut, they can fall onto the staggered first pad 7 below, preventing the second sheet 8 and the second pad 9 from falling too far and shifting.

[0036] When using this welding machine for geocell production, the conveyor belt 12 above the base plate 1 is started. The conveyor belt 12 carries the first sheet 6 set on the top surface for transportation. After the first sheet 6 is moved to the designated working position, the machine stops running. The worker places the third sheet 10 of the specified size at the bottom of the pressing plate 42, and then starts the two vacuum pumps 43 at the top of the pressing plate 42. The vacuum pumps 43 start working and adsorb the third sheet 10 through the adsorption tank 44 below. Then the worker starts the first motor 59 and the second motor 510. The first motor 59 and the second motor 510 drive the first transmission chain 55 and the second transmission chain 57 to rotate through the drive gear 512 set at the output end. The two transmission chains drive the two sets of rotating rollers to rotate in different directions, so that the first pad 7 or the second pad 9 between the rotating rollers is pushed out by the rolling force of the rotating rollers. The cylinder 41 is started, so that the output end of the cylinder 41 drives the pressing plate 42 to press down. The pad cutter 47 at the bottom of the pressing plate 42 first contacts the second pad 9. The bottom of the second pad 9 contacts the second sheet 8, thereby cutting the second pad 9. Then the pressing plate 42 continues to press down, and the sheet cutters 48 on both sides of the bottom of the pressing plate 42 cut the second sheet 8. Subsequently, the second pad 9 presses down on the second sheet 8, causing it to fall into the first pad 7 below. Several first pads 7 are fixed between two rotating rollers, capable of supporting the second sheet 8 and the second pad 9 above. Then, the pressing plate 42 drives the adsorbed third sheet 10 to contact the second pad 9, while the pad cutter 47 at the bottom cuts the first pad 7. The first pad 7, the second sheet 8, and the second pad 9 fall onto the top surface of the first sheet 6 below. The output end of the cylinder 41 drives the third sheet 10 to continuously press downwards. The pad cutter 47 and the sheet cutter 48 pass around the conveyor belt 12. At this time, several ultrasonic welding heads 46 inside the pressing plate 42 perform ultrasonic welding between the sheets and pads below, thereby forming the required geocell. After welding and pressing, the vacuum pump 43 stops working, and the output end of the cylinder 41 drives the pressing plate 42 to return to its original position. The staff repositioned the second sheet 8 between the two drive rollers 22, and started the first motor 59 and the second motor 510 to re-discharge the first pad 7 and the second pad 9, thereby facilitating the subsequent pressing and welding of the geocells.

[0037] The working principle of this invention: The welding machine for geocell production of this invention is equipped with a pressing structure 4. The pressing plate 42 of the pressing structure 4 can cut several sheets and pads below, while several ultrasonic welding heads 46 inside the pressing plate 42 weld the stacked sheets and pads to form the required geocell. The feeding structure 5 is equipped with several pads between two sets of rotating rollers. Different sets of rotating rollers are driven by chains, so that the motors on both sides can drive the rotating rollers of the same set to rotate in different directions through the chains, thereby completing the discharge of the pads. By setting pads between the rotating rollers, several first pads 7 and second pads 9 are arranged vertically and staggered, so that the pads and sheets can be welded evenly during the welding process. At the same time, after the second pads 9 and the second sheets 8 are cut, they can fall onto the staggered first pads 7 below, preventing the second sheets 8 and the second pads 9 from falling too far and shifting.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
