[0026] Reference Figures 1 to 3According to an embodiment of the present invention, a continuous feeding valve welding machine includes a frame 100, a packaging bag valve welding mechanism 200, a packaging bag positioning mechanism 300 and a feeding mechanism. The packaging bag valve welding mechanism 200 is arranged on the frame 100; the packaging bag positioning mechanism 300 is arranged on the frame 100, and a packaging bag transfer mechanism is arranged between the packaging bag positioning mechanism 300 and the packaging bag valve welding mechanism 200; the feeding mechanism includes two first baffle plates 410, a second baffle plate 420, a packaging bag conveying device 430 and a material moving device 440, and the two first baffle plates 410 are arranged side by side. Placed on the frame 100, the packaging bag conveying device 430 is arranged between the two first baffle plates 410 along the first baffle plate 410, and the second baffle plate 420 is arranged opposite to the packaging bag conveying device 430. The two first baffle plates 410, the second baffle plate 420 and the packaging bag conveying device 430 are enclosed to form a storage space 450. The storage space 450 has at least two packaging bag storage stations distributed along the first baffle plate 410. The material moving device 440 is used to convey packaging bags from the packaging bag storage station close to the second baffle plate 420 to the packaging bag positioning mechanism 300.

[0027] The first baffle plate 410, the second baffle plate 420 and the packaging bag conveying device 430 of the feeding mechanism are used to form a storage space 450 with at least two packaging bag storage stations. Each packaging bag storage station can store packaging bags, thereby increasing the capacity of the feeding mechanism to store packaging bags. During the valve welding process of the valve welding machine, the material moving device 440 obtains the packaging bags from the packaging bag storage station close to the second baffle plate 420 and then conveys the packaging bags to the packaging bag positioning mechanism 300. During this process, there is no need to pause the valve welding, and new packaging bags can be replenished and stored in the feeding mechanism from the packaging bag storage station away from the second baffle plate 420, and the packaging bag conveying device 430 can convey the packaging bags on the packaging bag storage station away from the second baffle plate 420 to the packaging bag storage station close to the second baffle plate 420, thereby realizing continuous loading.

[0028] Reference Figures 1 to 3 According to some embodiments of the present invention, the frame 100 is provided with an adjustment structure, which can adjust the distance between the two first baffles 410. Thus, the distance between the two first baffles 410 can be adjusted according to the size of the packaging bag, and then the size of the storage space 450 can be adjusted, so that the loading mechanism can store packaging bags of different sizes.

[0029] Reference Figures 1 to 3 According to some embodiments of the present invention, the adjustment structure includes an adjustment bracket 500, and each first baffle plate 410 is connected to at least two adjustment brackets 500 on a side facing away from the packaging bag conveying device 430, thereby stably adjusting the distance between the two baffle plates.

[0030] Reference Figures 1 to 3 According to some embodiments of the present invention, the two first baffle plates 410 are arranged side by side in the front-to-back direction, and the length of the first baffle plate 410 is along the left-to-right direction, wherein the first baffle plate 410 is connected to the corresponding adjustment bracket 500 so as to be slidable left and right, or the adjustment bracket 500 is installed on the frame 100 so as to be slidable left and right, thereby, the distance between the first baffle plate 410 and the second baffle plate 420 can be adjusted left and right.

[0031] Reference Figures 1 to 3 According to some embodiments of the present invention, two first baffles 410 are arranged side by side in the front-to-back direction. The adjustment bracket 500 includes a support member 510 and an adjustment member 520. The support member 510 is mounted on the frame 100. The adjustment member 520 is slidably mounted on the support member 510. A locking member 530 for locking the adjustment member 520 is provided between the adjustment member 520 and the support member 510. A mounting groove 411 is formed on a side of the first baffle 410 facing away from the packaging bag conveyor 430. The mounting groove 411 extends in the left-right direction. The adjustment member 520 is connected to a slider 540, which is slidably mounted in the mounting groove 411. Through the above arrangement, the first baffles 410 are easy to install and disassemble, and the spacing between the two first baffles 410 and the spacing between the first baffle 410 and the second baffle 420 can be adjusted.

[0032] Reference Figures 1 to 3 According to some embodiments of the present invention, the cross-sectional shape of the mounting groove 411 is T-shaped, and the shape of the slider 540 matches the cross-sectional shape of the mounting groove 411. Through the above setting, the cooperation between the slider 540 and the mounting groove 411 can prevent the first baffle plate 410 from detaching from the adjustment bracket 500.

[0033] Reference Figures 1 to 3 It is conceivable that the above-mentioned adjustment structure can also be set up in other ways. For example, the two first baffles 410 can be slidably installed on the frame 100 through slide rails. The adjustment structure includes a motor and two screw rods. The output shaft of the motor is coaxially connected to the two screw rods in sequence. The transmission threads on the two screw rods rotate in opposite directions. The two screw rods are transmission-connected to the two first baffles 410 one by one.

[0034] Reference Figures 1 to 3 According to some embodiments of the present invention, the second material stopper 420 is tilted toward a side away from the packaging bag conveying device 430, and the packaging bag positioning mechanism 300 is located on the side of the second material stopper 420 away from the packaging bag conveying device 430. With this arrangement, the second material stopper 420 can prevent the packaging bags from escaping the packaging bag conveying device 430. At the same time, the tilted second material stopper 420 can avoid the material transfer device 440, allowing the material transfer device 440 to transfer the packaging bags.

[0035] Reference Figures 1 to 3 According to some embodiments of the present invention, the loading mechanism includes a bag sensor located at a bag storage station near the second material stopper 420 or at the material transfer device 440. The bag conveyor 430 can be started and stopped based on the detection results of the bag sensor. Therefore, when the bag sensor detects a shortage of bags at the bag storage station near the second material stopper 420, the bag conveyor 430 is activated to transfer bags from other bag storage stations to the bag storage station near the second material stopper 420.

[0036] Reference Figures 1 to 3 It is conceivable that, since the time required for the valve welding machine to complete the valve welding work of each packaging bag is basically the same, and the number of packaging bags stored in each packaging bag storage station is usually the same, the time required for the material transfer device 440 to transport the packaging bags on the packaging bag storage station close to the second material baffle 420 is basically the same, and the packaging bag conveying device 430 only needs to start and stop periodically. Therefore, the above-mentioned packaging bag sensing device does not need to be set.

[0037] Reference Figures 1 to 3 According to some embodiments of the present invention, the material moving device 440 includes a horizontal moving component 441, a lifting component 442 and a suction cup 443. The horizontal moving component 441 is installed on the frame 100, the lifting component 442 is installed on the horizontal moving component 441, and the lifting component 442 is installed on the suction cup 443. The horizontal moving component 441 can drive the lifting component 442 to move horizontally, and the lifting component 442 can drive the suction cup 443 to move up and down. Through the above arrangement, the material moving device 440 can transport the packaging bags on the packaging bag storage station near the second baffle plate 420 to the packaging bag positioning mechanism 300.

[0038] It should be noted that the material moving device 440 may also be provided in other ways. For example, the material moving device 440 may be provided as a robotic arm, on which a suction cup 443 for holding the packaging bag is mounted.

[0039] Reference Figures 1 to 3 According to some embodiments of the present invention, the packaging bag valve welding mechanism 200 includes a bag-stretching device 210, a valve welding device 220 and an upper valve device 230. The upper valve device 230 is used to supply valves to the valve welding device 220. The bag-stretching device 210 is used to stretch open the packaging bag positioned by the packaging bag positioning mechanism 300 and transport the packaging bag to the valve welding device 220. The valve welding device 220 is used to weld the valve on the stretched packaging bag. Through the above-mentioned settings, the continuous feeding valve welding machine provided by the present invention can perform the processes of positioning, stretching, and valve welding on the packaging bag in sequence, thereby completing the work of welding valves to the packaging bag.

[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
