[0034] like Figures 1 to 4 As shown, this embodiment provides an uninterrupted bag conveying mechanism, including a bag storage seat 1 and a bag retrieval suction cup 2. Two bag storage seats 1 are arranged in an array and mounted on a circulating drive. A plurality of packaging bags 6 can be vertically stacked on the bag storage seat 1. The bag retrieval suction cup 2 is arranged above the bag storage seat 1, and the bag retrieval suction cup 2 is driven and connected to a lifting and translation arm 4.

[0035] During actual use, the bag storage holder 1 is first filled with packaging bags 6, specifically the handle mounting holes 601 are aligned with the serially connected vertical rods 101 for positioning. The lifting and translational arm 4 then drives the bag retrieval suction cup 2 down to the bag storage holder 1 to contact the packaging bags 6, lifting and sucking up a packaging bag 6 and then delivering it horizontally, facilitating processes such as handle buckling on the packaging bag 6. After the packaging bags 6 in the bag storage holder 1 are used up, the loop drive moves the next bag storage holder 1 filled with packaging bags 6 to the bottom of the bag retrieval suction cup 2, while the empty bag storage holder 1 is removed from under the bag retrieval suction cup 2, making it convenient for staff to add packaging bags 6 at any time. Finally, after the packaging bags 6 in the second bag storage holder 1 are used up, the first bag storage holder 1 is reset, ensuring uninterrupted operation of the equipment.

[0036] The lifting and translating arm 4 comprises a suction cup bracket 401, a translating rail 402, and a lifting assembly. The translating rails 402 are mounted on both the left and right sides of the suction cup bracket 401. The lifting assembly is mounted on the suction cup bracket 401, and the bag-removing suction cup 2 is located at the bottom of the lifting assembly. The horizontally symmetrical translating rails 402 enhance the stability of the packaging bag 6 during translational transport, improve the accuracy of conveying and positioning, and facilitate subsequent processing steps such as crimping the handle of the packaging bag 6.

[0037] The lifting assembly includes a lifting connecting rod 403, a connecting rod base plate 404 and a lifting push plate 405. The lifting connecting rod 403 passes through the sleeve suction cup bracket 401. The connecting rod base plate 404 is installed on the top of the lifting connecting rod 403, and the bag taking suction cup 2 is installed on the bottom. A return spring 5 is arranged between the suction cup bracket 401 and the connecting rod base plate 404. The lifting push plate 405 is arranged above the connecting rod base plate 404 at one end of the translation rail 402 close to the bag storage seat 1.

[0038] When the suction cup bracket 401 moves above the bag storage holder 1, the lifting push plate 405 presses down on the connecting rod base plate 404, compressing the return spring 5. The entire lifting assembly descends, and the bag-removing suction cup 2 contacts and holds the bag 6 at the top of the stack in the bag storage holder 1. Subsequently, the lifting push plate 405 returns to its upper position, and the lifting assembly, under the elastic force of the return spring 5, links the bag-removing suction cup 2 and rises. The suction cup bracket 401 then translates to the other end of the translation rail 402, completing the removal and delivery of the bag 6.

[0039] In addition, since the bottom surface of the lifting push plate 405 is higher than the upper end surface of the connecting rod base plate 404, it is convenient for the lifting assembly to be moved out from above the bag storage holder 1. By separating the remaining components of the lifting assembly from the lifting push plate 405, the weight of the lifting assembly components is effectively reduced, reducing the operating load of the translation slide 402. Furthermore, the translation and lifting speeds can be increased, the working efficiency of the equipment can be improved, the jamming faults can be reduced, and the mechanical life can be extended.

[0040] The left and right sides of the suction cup bracket 401 are symmetrically provided with bag taking suction cups 2. The symmetrically designed bag taking suction cups 2 can ensure stable grabbing of the packaging bags 6 one by one, and avoid failure of grabbing caused by air leakage of the bag taking suction cups 2.

[0041] A bag placement platform 7 is provided below the translation rail 402. A discharge rail 8 is provided to the side of the translation rail 402 at the end opposite the bag storage holder 1. A vertically downward-pointing lifting suction cup 801 is slidably sleeved on the discharge rail 8, and one end of the discharge rail 8 protrudes from the bag placement platform 7. After the bag-taking suction cup 2 places the bag 6, it can be directly placed on the bag placement platform 7 for processes such as handle buckling. The discharge rail 8, in conjunction with the lifting suction cup 801, quickly removes the processed bag 6 from the device.

[0042] The circulating drive includes a reciprocating slide 3, and the bag storage holder 1 is slidably sleeved on the reciprocating slide 3. The reciprocating slide 3 is short in length and can drive the two bag storage holders 1 to alternately run under the bag removal suction cup 2, effectively streamlining the equipment structure and reducing the space occupied by the equipment.

[0043] The bag storage holder 1 is provided with a transverse slot 102 symmetrically on the left and right sides, and a limit lever 103 is installed in the transverse slot 102. The packaging bag 6 is placed between the limit levers 103 on the left and right sides. The adjustable limit lever 103 facilitates the adaptation of packaging bags 6 of different sizes.

[0044] The packaging bag 6 has a handle mounting hole 601 formed on its upper side. A connecting rod 601 is detachably connected to the corresponding handle mounting hole 601 on the bag storage holder 1. The connecting rod 101 includes a left rod 1011 and a right rod 1012 symmetrically arranged on both sides. The tops of the left and right rods 1011 and 1012 are both chamfered (not shown).

[0045] The separate design of the left and right uprights 1011 and 1012 facilitates adjustment of the connecting rod 101 to the size of the handle mounting hole 601, improving the adaptability of the device. The chamfered edges allow the packaging bag 6 to smoothly enter and exit the connecting rod 101, preventing the packaging bag 6 from being scratched by the sharp edges of the connecting rod 101.

[0046] The bag storage holder 1 is provided with a lifting protrusion 9 in the middle. The width of the lifting protrusion 9 is smaller than that of the packaging bags 6. The lifting protrusion 9 can cause the middle of the packaging bags 6 stacked in the bag storage holder 1 to tilt upward, making it easier to form a certain space at the edges of the packaging bags 6 due to the tilting, thereby facilitating the separation of the packaging bags 6 one by one and avoiding problems such as sticking or failure to absorb. Example 2

[0047] like Figure 5 As shown, this embodiment differs from the first embodiment in that the circulating drive is a circulating conveyor belt 10, with multiple bag storage holders 1 mounted around the circulating conveyor belt 10, and vertically spaced apart by holder partitions 11. During operation, the multiple bag storage holders 1 are separated by multiple holder partitions 11 on the circulating conveyor belt 10, resulting in a simpler design than the reciprocating mechanism of the first embodiment. Furthermore, staff members can add bags 6 to the machine while maintaining the position at the front end of the circulating conveyor belt 10, eliminating the need to alternately add bags 6 to the left and right sides of the bag removal suction cup 2, making it more convenient to use than the first embodiment.

[0048] The above content is a further detailed description of the present invention in combination with specific preferred implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
