[0026] Example 1

[0027] Please see Figures 1 to 7 The present invention preferably provides the following technical solution: a lamp tube film-threading machine, comprising: a lamp tube pushing device; a bracket 411 horizontally mounted with the lamp tube pushing device; a horizontally movable horizontal pushing component mounted on the bracket 411; a film bag feeding rack mounted with the execution end of the horizontal pushing component; a suction cup assembly on the film bag feeding rack for openings at the front ends of several film bags; and a duckbill support structure on the forward end of the film bag feeding rack, the duckbill support structure corresponding one-to-one with the opening position at the front end of the film bag; under the action of the horizontal pushing component, the film bags on the film bag feeding rack move towards the duckbill support structure, so that the duckbill support structure enters the opening position at the front end of the film bag and expands it.

[0028] This implementation example Figure 1 , 2As shown in Figures 3 and 4, the lamp pushing device and the horizontal pushing component installed on the bracket 411 have opposite running directions. That is, the horizontal pushing component, the film bag feeding rack set on the horizontal pushing component, the suction cup component and the duckbill support structure set on the film bag feeding rack are all assembled in front of the lamp pushing device, and the lamp pushing device is installed in front of the horizontal pushing component.

[0029] The film bags placed on the film bag feeding rack can be passively opened by the suction cup assembly. When the horizontal pushing assembly moves the film bag feeding rack horizontally, the film bags that are passively opened by the suction cup assembly can be put onto the duckbill support structure one by one. At this time, through the action of the duckbill support structure, the opening position at the front end of the film bag can be expanded, thereby completing the preparation work before the film bag is loaded into the tube.

[0030] Then, the lamp pushing device is driven, which can push several lamps forward toward the duckbill support structure and simultaneously realize the bagging process of several lamps and several film bags, which significantly improves work efficiency and enhances product consistency and quality.

[0031] Furthermore, the horizontal actuation assembly includes a movable plate 412 slidably mounted on the upper surface of the bracket 411; and a first electrically operated telescopic rod 426 mounted on the bracket 411, wherein a connector 427 at the output end of the first electrically operated telescopic rod 426 is assembled with the movable plate 412, as shown below. Figure 6 As shown, under the action of the first electric telescopic rod 426, the movable plate 412 can move closer to or away from the duckbill support structure on the surface of the bracket 411.

[0032] Furthermore, the film bag loading rack includes a support member 413, wherein the two ends of the support member 413 are fixedly assembled with the upper surface of the moving plate 412 via support plates 414 provided at their ends, and a plurality of support columns 415 are fixed in the middle; a support platform 416 is provided on the top of the plurality of support columns 415; and a plurality of film placement frames 417 are assembled on the top of the support platform 416 and used for placing a plurality of film bags, wherein each film placement frame 417 is provided with a plurality of through holes.

[0033] like Figure 1-4 As shown in Figures 5 and 6, since several film-laying frames 417 are arranged in an array on the surface of the support platform 416, when the moving plate 412 moves closer to or further away from the duckbill support structure under the action of the first electric telescopic rod 426, several film bags can be simultaneously pushed towards the position of the duckbill support structure.

[0034] Furthermore, the suction cup assembly includes support bases 418 fixed on both sides of the movable plate 412; a first mounting frame 419 and a second mounting frame 422 disposed between the two support bases 418 and distributed below and above, wherein a plurality of first electric push rods 420 and a plurality of second electric push rods 423 are symmetrically mounted on the first mounting frame 419 and the second mounting frame 422; a first U-shaped frame 421 and a second U-shaped frame 424 fixed to the telescopic ends of the plurality of first electric push rods 420 and the plurality of second electric push rods 423; and a plurality of electric suction cups 425 disposed on the opposite sides of the first U-shaped frame 421 and the second U-shaped frame 424, with the two sets of electric suction cups 425 respectively symmetrically placed on the upper and lower surfaces of the film frame 417.

[0035] like Figure 6 , 7 As shown, the first mounting bracket 419, the first electric push rod 420, the first U-shaped frame 421, and the second mounting bracket 422, the second U-shaped frame 424 are distributed below and above each other. Electric suction cups 425 are respectively mounted on opposite sides of the first U-shaped frame 421 and the second U-shaped frame 424. When the distance between the two electric suction cups 425 is adjusted by the first electric push rod 420 and the second electric push rod 423, the distance between the two electric suction cups 425 and the film placement frame 417 is further adjusted, thereby achieving adjustment of the suction force. Figure 6 , 7 As shown, by synchronously driving two electric suction cups 425, the front section of the film bag can be passively opened.

[0036] Furthermore, the duckbill support structure includes two assembly strips 124, which are fixed to the upper and lower parts of the lamp tube pushing device near the film bag feeding rack, respectively; two sets of second electric telescopic rods 120 are installed on the opposite sides of the two assembly strips 124 and are symmetrically distributed, with an assembly plate 121 fixed to the telescopic end of each set of several second electric telescopic rods 120; and several upper clamping nozzles 122 and several lower clamping nozzles 123 are respectively arranged on the opposite sides of the two assembly plates 121, wherein the upper clamping nozzles 122 and lower clamping nozzles 123 are symmetrically distributed and arranged opposite each other; furthermore, the length of the lower clamping nozzles 123 is greater than the length of the upper clamping nozzles 122, and the side of the upper clamping nozzles 122 and lower clamping nozzles 123 near the film bag feeding rack is arc-shaped.

[0037] like Figure 5 , 6 As shown in Figure 7, several upper clamping nozzles 122 and several lower clamping nozzles 123 are symmetrically distributed vertically. When the two second electric telescopic rods 120 are operated, the spacing between the several upper clamping nozzles 122 and several lower clamping nozzles 123 can be adjusted. During this process, when several film bags are placed on several sets of upper clamping nozzles 122 and lower clamping nozzles 123, the opening of several film bags can be passively expanded.

[0038] It is worth noting that the length of the lower clamp 123 in this application is greater than the length of the upper clamp 122, and the sides of the upper clamp 122 and the lower clamp 123 near the film bag feeding rack are both arc-shaped. The arc-shaped design makes it easier for the upper clamp 122 and the lower clamp 123 to extend into the film bag, while the length design allows the lower clamp 123 to enter the film bag first, further facilitating the installation of the film bag.
