Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a fully automatic welding nozzle machine. Background Technology

[0002] In the packaging industry, especially in the field of pouch packaging, fully automatic nozzle welding machines play a key role in the production of composite film flexible packaging products, such as pouch beverages and jellies with spouts, pouch ketchup in food, and pouch laundry detergent and washing powder in daily products. Their core function is to accurately complete the nozzle welding process on the pouch, which greatly improves the level of automation and production efficiency of packaging.

[0003] Existing welding nozzle machines struggle to efficiently organize and transport disordered nozzles in the nozzle feeding stage. Traditional feeding methods often lack a systematic approach, resulting in nozzles exhibiting varying postures during transport and making it impossible to guarantee a uniform preset posture. This leads to difficulties in precise alignment during subsequent welding, significantly impacting welding quality and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic welding nozzle machine. It features a nozzle feeding assembly, specifically a vibrating elevator that organizes disordered nozzles into a preset posture and continuously conveys them to a vertical vibrator. The vertical vibrator uses high-frequency vibration to propel the nozzles smoothly. Clamping cylinders hold the nozzles, and blocking cylinders block subsequent nozzles. A forward cylinder, in conjunction with the vertical vibrator, moves the nozzles linearly to the welding position. During retraction, all components return to their original positions in an orderly manner. Simultaneously, a vibrating elevator is used for feeding. By utilizing the orderly feeding method of the vibrating elevator, combined with the coordinated action of the vertical vibrator and cylinders, unnecessary movements during nozzle feeding are reduced, ensuring uniform nozzle posture and stable conveying. This lays the foundation for precise welding, improves the automation and efficiency of nozzle feeding, adapts to the feeding needs of different production scenarios, and solves the problem of existing welding nozzle machines struggling to efficiently organize and orderly convey disordered nozzles during the nozzle feeding stage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

An internal thread block is threadedly connected to the outer wall of the adjusting rod. The top of the internal thread block is fixedly connected to the bag hopper.

[0015] The two guide rods are not on the same horizontal line, which causes the bag hopper to be tilted.

[0043] A specific application of this embodiment is as follows: When using this device, the vibrating elevator 121 first serves as the starting device for feeding the suction nozzles. It first organizes the disorderly stacked suction nozzles according to preset postures such as opening direction and orientation, ensuring that the output suction nozzles have consistent postures. At the same time, it continuously conveys the organized suction nozzles to the vertical vibrator 212, providing stable and uniform material for subsequent conveying. The vertical vibrator 212 generates high-frequency reciprocating vibration through its internal electromagnetic vibrator, which pushes the suction nozzles to move smoothly forward along the track, solving the problem of chaotic postures during the suction nozzle conveying process. When the suction nozzle reaches the designated position, the clamp cylinder 214 clamps the suction nozzle, the blocking cylinder 215 descends to block subsequent suction nozzles from piling up, and the forward cylinder 213 pushes the suction nozzles to move linearly to the welding position. When retracting, all components are reset in an orderly manner, realizing cyclic feeding. Through the design of "vibrating feeding + cylinder coordinated clamping and positioning", the unnecessary movements of the suction nozzle conveying are reduced, thereby significantly improving the stability and accuracy of suction nozzle feeding, laying the foundation for accurate welding in the subsequent process, and ensuring the efficient and orderly feeding process.

[0044] In the moving component 22, the second support frame 221 is fixed on the workbench 1, providing support for the entire component; two guide rods 222 are fixed to the second support frame 221 in a non-horizontal state, and the slider 223 is sleeved on the guide rods 222 and fixedly connected to the bag hopper 12. This ensures that the bag hopper 12 always maintains an inclined posture, allowing the bags inside to slide naturally towards the picking end by gravity, ensuring continuous supply. When the handle 225 is turned, the adjusting rod 224 welded to the handle 225 rotates on the second support frame 221 through the bearing, driving the internal thread block 226 threaded to it to move. In turn, the internal thread block 226 drives the bag hopper 12 to slide along the guide rod 222, realizing the adjustment of the front and rear position of the hopper, ensuring that the bags are in a position that is easy to grasp; at the same time, in the adjusting component 23, the shaft 231 is rotatably connected to the second support frame 221 through the bearing, and its outer wall is fixed with a connecting plate 232 and two rocker arms 234; one end of the rocker arm cylinder 233 is hinged to the support. On the mounting base of frame 221, the other end is hinged to the connecting plate 232. When the piston rod of the rocker arm cylinder 233 extends, it pushes the connecting plate 232 to drive the shaft 231 to rotate, causing the two rocker arms 234 to swing forward. At this time, the suction cups 235 on the rocker arms 234 are aligned with the bags in the bag hopper 12 and adsorb the bags. Then the piston rod of the rocker arm cylinder 233 retracts, driving the shaft 231 to rotate in the opposite direction, and the rocker arms 234 swing backward, moving the adsorbed bags to the front of the welding station, completing the automatic bag picking and transfer action, and preparing for the subsequent correction and welding of the welding fixture. The moving component 22 ensures smooth bag supply by adjusting the position of the hopper, and the adjusting component 23 drives the rocker arm through the rocker arm cylinder 233 to complete the automatic bag picking and transfer, realizing "automatic bag loading with swing arm". While reducing manual intervention, it can be combined with manual adjustment to adapt to different bag sizes. Through precise transfer before fixture correction, it provides a basic guarantee for the subsequent welding quality and improves bag loading efficiency and compatibility.

[0045] After receiving the material from the nozzle feeding assembly and adjustment assembly, the bag positioning 244, in conjunction with the fixture, places the nozzle into the bag and aligns it. The welding fixture moving unit 243 drives the fixture holding the material to move back and forth, reducing ineffective movement time while increasing welding time. The heating plate 246 continuously heats the material, and the motor 242 presses the material to complete the welding. Subsequently, the fixture retracts, the cylinder releases, and the discharge suction cup 245 discharges the finished product. During this process, the fixture's design of simultaneously holding and moving the material significantly improves welding stability. Combined with continuous heating from the heating plate, this ensures a strong weld. Two welding modes adapt to different needs, and the discharge suction cup enables continuous production, ultimately solving the problem of poor stability in machines on the market, guaranteeing welding quality, and improving overall production efficiency.
