Description

Technical Field

[0001] The utility model relates to a welding nozzle machine, in particular to a combined high-speed feeding mechanism of the welding nozzle machine. Background Art

[0002] A nozzle welding machine is a device that welds a nozzle onto a film bag. Previous nozzle welding machines generally include a conveyor line, a rotating suction cup grasping structure 100, and an assembly line 200. The film bag is transported from the front end to the rear end of the conveyor line, and then grasped by the rotating suction cup grasping structure 100 to the front end of the assembly line 200.

[0003] The rotary suction cup gripping structure 100 comprises two oppositely positioned suction cup frames and a suction cup gripping assembly. One suction cup gripping assembly places the gripped film bag at the front end of the assembly line 200, while the other suction cup gripping assembly grabs the film bag at the rear end of the conveyor line. While this method improves gripping efficiency, the film bag has a long travel distance after gripping, resulting in a slow conveying speed, which results in low conveying efficiency and a mismatch between the assembly efficiency of the assembly line 200. Because the cantilever 300 and the suction cup frame on the cantilever 300 of the rotary suction cup gripping structure 100 rotate, excessively high speeds create significant centrifugal force and inertia, causing the cantilever 300 to vibrate and the film bag to bend, fold, and deform, resulting in inaccurate positioning of the film bag during placement or gripping. Consequently, the speed of the rotary suction cup gripping structure 100 cannot be increased. Therefore, the applicant has designed a combined high-speed loading mechanism for a welding nozzle machine to address this issue. Summary of the Invention

[0030] Reference Figures 1 to 5 The utility model discloses a combined high-speed feeding mechanism of a welding nozzle machine, including a feeding frame 1, a suction cup grabbing mechanism 2 and a pressure belt conveying mechanism 3 arranged on the feeding frame 1, the suction cup grabbing mechanism 2 includes a grabbing moving mechanism, a grabbing translation plate 4 driven by the grabbing moving mechanism, a grabbing lifting structure arranged on the translation plate, a suction cup frame 5 driven by the grabbing lifting structure and a suction cup assembly 6 arranged on the suction cup frame 5. The specific structure is that the grabbing moving mechanism includes a grabbing moving cylinder 7 and a grabbing moving guide rail assembly 8 installed on the feeding frame 1, the grabbing moving cylinder 7 is fixed to the feeding frame 1 through a front cylinder plate and a rear cylinder plate, the grabbing translation plate 4 is connected to the grabbing moving cylinder 7 and the grabbing moving guide rail assembly 8; the grabbing lifting structure is a grabbing lifting cylinder 9 installed on the grabbing translation plate 4, the suction cup frame 5 is connected to the grabbing lifting cylinder 9, and the grabbing moving guide rail assembly 8 is an existing component and is not described in detail.

[0031] Therefore, through the above structure, the grabbing moving cylinder 7 can drive the grabbing translation plate 4 and the suction cup frame 5 to move to the rear end of the conveyor line 10, and then the grabbing lifting cylinder 9 drives the suction cup frame 5 to descend to the grabbing position, the suction cup in the suction cup assembly 6 sucks the film bag, and then the grabbing lifting cylinder 9 drives the suction cup frame 5 to rise and reset, and the grabbing moving cylinder 7 can drive the grabbing translation plate 4 and the suction cup frame 5 to move to the discharge position, and then the grabbing lifting cylinder 9 drives the suction cup frame 5 to descend to the discharge position, the suction cup in the suction cup assembly 6 releases the film bag so that the film bag falls into the discharge position, and the grabbing lifting cylinder 9 rises and drives the suction cup frame 5 to reset to start the next cycle.

[0032] As shown in the figure, the pressure belt conveyor mechanism 3 includes a compacting and lifting mechanism, a lower conveyor belt mechanism and an upper compacting belt mechanism. The film bag on the conveyor line 10 can be grabbed by the suction cup grabbing mechanism 2 and transported to the conveyor belt 11 of the lower conveyor belt mechanism, and the compacting and lifting mechanism can drive the upper compacting belt mechanism to press the film bag on the conveyor belt 11 onto the conveyor belt 11. The above method realizes the conveying in a compacting bag manner. When the conveyor belt 11 is conveying the film bag, there is an upper compacting belt mechanism above the film bag. The film bag is compacted by the compacting belt of the upper compacting belt mechanism. In this way, the film bag will not be deformed or fly out when moving at high speed. Not only is the conveying speed fast, but the conveying position is also accurate. Of course, the pressure belt is passively rotated, and the suction cup assembly 6 is an existing component, so it is not described in detail.

[0033] As shown in the figure, the specific structure is that the lower conveyor belt 11 mechanism also includes a lower conveying motor 12, a front conveying roller 13, and a rear conveying roller 14. The conveyor belt 11 is arranged on the front conveying roller 13 and the rear conveying roller 14. The front conveying roller 13 is provided with a front wheel shaft 15, and the front wheel shaft 15 is connected to the front conveying roller 13 through a flat key so as to rotate as a whole. The front wheel shaft 15 is arranged on the loading rack 1 through a bearing seat, and the rear conveying roller 14 is fixedly connected to the loading rack 1 through the rear wheel shaft 16. The screw locks the rear wheel shaft 16 and the loading rack 1, and the rear wheel shaft 16 is connected to the rear conveying roller 14 through a bearing. The front wheel shaft 15 is driven to rotate by the lower conveying motor 12, and the lower conveying motor 12 is provided with a driving pulley 17. The end of the front wheel shaft 15 is provided with a driven pulley 18, and a transmission belt 19 is provided on the driving pulley 17 and the driven pulley 18. Through the above structure, the power of the lower conveying motor 12 can be transmitted to the front conveying roller 13 to rotate it, thereby driving the conveyor belt 11 to move. The front conveying roller 13 and the rear conveying roller 14 are preferably synchronous rollers, and the conveyor belt 11 is preferably a synchronous belt.

[0034] As a further structure, the lower conveyor belt 11 mechanism also includes an auxiliary support wheel 20 and an auxiliary support shaft 21. The auxiliary support wheel 20 is connected to the auxiliary support shaft 21 through a bearing, and the two ends of the auxiliary support shaft 21 are fixed to the loading rack 1 by screws. Because the upper pressure belt mechanism will exert a certain pressure on the film bag during the conveying process, the conveyor belt 11 needs more support to ensure that it will not be severely bent and deformed under the pressure of the upper pressure belt mechanism. The auxiliary support wheel 20 has no power to rotate with the conveyor belt 11.

[0035] As shown in the figure, the upper pressing belt mechanism includes a pressing lifting cylinder 22 fixed on the feeding frame 1, a lifting frame connected to the pressing lifting cylinder 22, a plurality of pressure rollers 27 rotatably connected to the lifting frame, and a pressure belt 23 arranged on the pressure roller 27. The pressing lifting cylinder 22 can drive the lifting frame, the pressure roller 27 and the pressure belt 23 to move and press the film bag on the conveyor belt 11. When the film bag is placed on the conveyor belt 11, the pressing lifting cylinder 22 will drive the lifting frame to rotate and the pressure roller 27 to descend, so that the pressure belt 23 presses the film bag and conveys it to After it is in the position, it will rise again, waiting for the next film bag to be delivered. As a further specific structure, the loading rack 1 includes two connecting rods 24 and a frame 25 connected to the two connecting rods 24. The frame 25 includes a top plate and a side plate connected to the top plate and arranged parallel to the top plate. The pressure roller 27 is located in the frame 25. The pressure roller 27 includes a roller and a roller shaft. The roller is connected to the roller shaft through a bearing, and the two ends of the roller shaft are fixed to the side plates. The roller has no power, so the roller will rotate with the movement of the pressure belt 23, and the pressure belt 23 will move with the delivery of the film bag.

[0036] As shown in the figure, the loading rack 1 is relatively provided with auxiliary feed plates 26, and the auxiliary feed plates 26 are fixed by screws. The lower conveyor belt 11 mechanism is located between the two auxiliary feed plates 26, and the end of the auxiliary feed plate 26 protrudes from the lower conveyor belt 11 mechanism. In this way, when the suction cup delivers the film bag, only the edge of the film bag is on the conveyor belt 11, and the other part is on the auxiliary feed plate 26. After the pressing belt 23 presses the edge of the film bag, the film bag can be pulled over by the conveyor belt 11. In this way, we can shorten the length of the lower conveyor belt 11 mechanism, thereby saving costs.

Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
