Description

Technical Field

[0001] This invention relates to the field of double-head welding machine technology, and more specifically, to a double-head welding machine for embossing rollers. Background Technology

[0002] Embossing rollers, as key equipment for pressing raised and recessed textures onto material surfaces, are widely used in industries such as papermaking, plastics, leather, metal foil, and synthetic rubber. Their main functions include giving products special textures, enhancing their appearance and quality, improving anti-counterfeiting properties, and improving material performance. For example, the decorative patterns on the surfaces of common everyday napkins and packaging paper are processed using embossing rollers.

[0003] In existing technologies, the manufacturing and repair of embossing rollers often employs double-head welding machines. However, such equipment has significant limitations in practical applications: the embossing roller cannot be automatically rotated during the welding process, requiring manual intervention to adjust its position. This increases reliance on operators, leading to higher labor costs. Furthermore, frequent manual operations not only reduce overall work efficiency and extend the work cycle but also increase the safety risks for personnel operating near the welding equipment, hindering the construction of an automated production environment.

[0028] The spring 32 makes the recycling hose 33 more stable. When the recycling bucket 34 moves, it stretches the recycling hose 33 so that it can move fully. When the second motor 36 is turned on, the output end drives the second threaded rod 38 to rotate through the second rotating rod 37. When the second threaded rod 38 rotates, it drives the pusher plate 39 to move closer or further away from each other inside the collection box 30. The filter plate 311 avoids the air pump 313 from causing blockage.

A flexible rod 513 is fixedly connected to the inner wall of the sliding rod 58. The end of the flexible rod 513 away from the sliding rod 58 is fixedly connected to the sliding limit ring 56. An anti-slip pad 512 is fixedly connected to the surface of the fixed rotating ring plate 59 away from the sliding rod 58.

The bidirectional electric push rod 511 is movably mounted on the support plate 12.

[0030] The first pulley 50 drives the belt 51 to rotate. When the belt 51 rotates, it drives the second pulley 52 to rotate on the surface of the supporting rod 53. When the second pulley 52 rotates, it drives the limiting ring 54 and the sliding limiting ring 56 to rotate together through the third rotating rod 55. The anti-slip pad 512 increases the friction and avoids slippage. When the bidirectional electric actuator 511 is turned on, the output end drives the fixed rotating ring plate 59 to move inside the sliding limiting ring 56 through the sliding rod 58 via the push rod 510. The flexible rod 513 and the limiting tension rod 57 make its position more stable when it moves. In operation, when the first motor 22 is turned on, its output end drives the first threaded rod 212 to rotate via the rotating rod 211. When the first threaded rod 212 rotates, it drives the moving plate 213 to move inside the slot 216 via the moving pulley 215. When the moving pulley 215 moves, it drives the moving rail 23 to move above the base 1, allowing the machine to fully adjust its operation according to rollers of different sizes. Simultaneously, when the moving rail 23 moves, it drives the welding robot 4 to move inside the moving groove 41 via the second connecting rod 42, enabling the machine to quickly weld rollers of different sizes. When the rotating rod 211 rotates, it drives the welding robot 4 to move inside the moving groove 41 via the gears. 210 drives the rack 26 to move on the surface of the thin rod 27. The telescopic rod 21 makes the position of the rack 26 more stable when it moves. When the rack 26 moves, it drives the fixed sleeve 2141 to move closer or further away from each other inside the moving rail 23, so that the machine can fully clamp rollers of different diameters. The rubber pad 2143 and the extrusion spring plate 2142 protect the rollers. When the second motor 36 is turned on, the output end drives the second threaded rod 38 to rotate through the second rotating rod 37. When the second threaded rod 38 rotates, it drives the pusher plate 39 to move closer or further away from each other inside the collection box 30, so that it extrudes the welding slag inside the collection box 30. This increases the machine's collection capacity. When the fixed sleeve 2141 moves, it moves the recycling bin 34 along with it. The movement of the recycling bin 34 stretches the recycling hose 33, allowing it to move fully. The spring plate 32 makes the recycling hose 33 more stable, preventing tangling and other problems. When the air pump 313 is turned on, the output end passes through the collection box 30, allowing welding slag to enter the collection box 30 through the recycling bin 34 and the recycling hose 33. The filter plate 311 prevents the air pump 313 from clogging. When the second rotating rod 37 rotates, it drives the belt 51 to rotate via the first pulley 50. When the belt 51 rotates, it drives the second pulley 52 to support the thin rod. The surface of 53 rotates. When the second pulley 52 rotates, it will drive the limiting ring 54 and the sliding limiting ring 56 to rotate together through the third rotating rod 55, so that the machine can effectively rotate the roller during welding, improving the welding efficiency of the machine. At the same time, when the bidirectional electric push rod 511 is opened, the output end will drive the fixed rotating ring plate 59 to move inside the sliding limiting ring 56 through the push rod 510, so as to further fix the roller and avoid position displacement during welding. The anti-slip pad 512 increases the friction to avoid slippage. The soft rod 513 and the limiting tension rod 57 make its position more stable when moving.
