Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a packaging bag boxing mechanism. Background Technology

[0002] The finished products on the production line need to be packed into packaging bags, and then transported by belt conveyor to the cartoning mechanism for packaging. The cartoning mechanism puts the packaging bags containing the products into the packaging boxes for packaging.

[0003] For example, the packaging bag boxing mechanism disclosed in Chinese Patent No. CN218199043U works on the principle that "the counterweight ball drives the piston plate to move downward, forming a negative pressure inside the piston cylinder, which causes the suction cup to adhere to the bottom of the packaging bag. As the suction cup rotates, the negative pressure automatically disappears, and the packaging bag is placed into the packaging box. It can achieve automatic adsorption and automatic placement of the packaging bag, which is very convenient to use and the adsorption is very stable." In actual use, the rotation of the suction cup drives the counterweight ball to rotate. However, when the counterweight ball rotates, the negative pressure it generates will slowly disappear. It is very likely that when the suction cup rotates to a certain angle, the negative pressure generated is insufficient to adsorb the packaging bag, thus affecting the stability of the packaging bag boxing.

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A packaging bag boxing mechanism includes a support frame and a conveyor belt rotatably connected to the support frame, wherein a moving mechanism is engaged in the upper inner cavity of the support frame.

[0006] The moving mechanism includes a moving frame, the lower end of which is engaged with the inner cavity of the upper end of the support frame, and an electric telescopic rod is fixedly connected to the upper end of the moving frame.

At this point, the electric telescopic rod continues to move downwards, placing the packaging bag inside the packaging box. Afterwards, the air pump is turned off, the negative pressure of the suction cup disappears, and the packaging bag is thus placed inside the packaging box, ensuring the stability of the packaging bag during packaging.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a packaging bag boxing mechanism, including a support frame 1 and a conveyor belt 2 rotatably connected to the support frame 1, and a moving mechanism 3 is engaged in the inner cavity of the upper end of the support frame 1;

[0024] The moving mechanism 3 includes a moving frame 31. The lower end of the moving frame 31 is engaged with the inner cavity of the upper end of the support frame 1. An electric telescopic rod 4 is fixedly connected to the upper end of the moving frame 31. An air pump 7 and a fixing plate 5 are fixedly connected to the upper and lower ends of the electric telescopic rod 4. An adsorption mechanism 6 is rotatably connected to the upper end of the fixing plate 5.

[0025] The adsorption mechanism 6 includes a rotating shaft 61, a suction cup 65, a first pipe 66, and a second pipe 610. The outer wall of the rotating shaft 61 is rotatably connected to the upper end of the fixed plate 5, and the inner wall of the rotating shaft 61 is provided with a vent hole. The upper end of the suction cup 65 is engaged with the inner wall of the fixed plate 5. The ends of the first pipes 66 that are far apart from each other are connected to the ends of the suction cups 65 that are far apart from each other, and the ends of the first pipes 66 that are close together are connected to the inner wall of the fixed plate 5. The lower end of the second pipe 610 is rotatably connected to the upper end of the rotating shaft 61, and the upper end of the second pipe 610 is connected to the upper end of the air pump 7.

[0026] The air pump 7 and the electric telescopic rod 4 are activated to move the fixing plate 5 downwards. This downward movement of the fixing plate 5 causes the suction cup 65 to move downwards as well. With the activation of the air pump 7, air enters the first pipe 66 and the second pipe 610 from the suction cup 65, creating negative pressure on the suction cup 65 and adsorbing the packaging bag. Then, the moving frame 31 moves to the right, positioning the packaging bag at the top of the packaging box 8. At this point, the electric telescopic rod 4 continues to move downwards, placing the packaging bag inside the packaging box 8. The air pump 7 is then turned off, eliminating the negative pressure on the suction cup 65 and allowing the packaging bag to be fully inserted into the packaging box 8, thus ensuring the stability of the packaging bag during packaging. Specifically, the moving mechanism 3 includes a first screw 32 and a first motor 33. Both ends of the first screw 32 are rotatably connected to the upper end of the support frame 1, and the outer wall of the first screw 32 is threadedly connected to the lower end of the moving frame 31. One end of the first motor 33 is fixedly connected to the left end of the support frame 1, and the output end of the first motor 33 is fixedly connected to the left end of the first screw 32.

[0027] like Figure 3 As shown, the first motor 33 rotates, driving the first screw 32 to rotate. The rotation of the first screw 32 causes the moving frame 31 to move, thereby driving the adsorption mechanism 6 to move to the left, so that the packaging bag enters the packaging box 8.

[0028] Specifically, a limiting rod is fixedly connected to the inner cavity at the upper end of the support frame 1, and the outer wall of the limiting rod is movably sleeved with the inner wall at the rear end of the movable frame 31, and a packaging box 8 is placed at the lower end of the support frame 1.

[0029] like Figure 3 As shown, the movable frame 31 can move horizontally during movement via the limit rod installed on it. Specifically, the adsorption mechanism 6 includes a first bevel gear 62, a second screw 63, and a second bevel gear 64. The upper end of the first bevel gear 62 is fixedly connected to the lower end of the rotating shaft 61. Both ends of the second screw 63 are rotatably connected to the inner wall of the fixed plate 5, and the outer wall of the second screw 63 is threadedly connected to the upper end of the suction cup 65. The ends of the second bevel gears 64 that are far apart from each other are fixedly connected to the ends of the second screw 63 that are close to each other, and the ends of the second bevel gears 64 that are close to each other are meshed with the outer wall of the lower end of the first bevel gear 62.

[0030] The rotation of the shaft 61 drives the first bevel gear 62 to rotate, which in turn drives the second bevel gear 64 to rotate. The rotation of the second bevel gear 64 causes the second screw 63 to rotate, thereby causing the suction cups 65 to move closer or further apart. This allows the suction cups 65 to adsorb packaging bags of different sizes, increasing the flexibility of adsorbing packaging bags.

[0031] Specifically, the adsorption mechanism 6 includes a driven gear 67, a second motor 68, and a driving gear 69. The inner wall of the driven gear 67 is fixedly connected to the outer wall of the upper end of the rotating shaft 61. The lower end of the second motor 68 is fixedly connected to the upper end face of the fixing plate 5. The lower end of the driving gear 69 is fixedly connected to the output end of the second motor 68, and the front end of the driving gear 69 is meshed with the rear end of the driven gear 67.

[0032] like Figure 6 As shown, the second motor 68 rotates to make the drive gear 69 rotate, which in turn drives the driven gear 67 to rotate, thereby causing the rotating shaft 61 to rotate. This, in turn, causes the first bevel gear 62, the second bevel gear 64, and the second screw 63 to rotate, thereby moving the suction cup 65. This allows the suction cup 65 to adsorb packaging bags of different sizes, increasing the flexibility of adsorbing packaging bags.

[0033] Specifically, the second pipe 610 and the first pipe 66 are telescopic pipes, and the telescopic length of the second pipe 610 is greater than the stroke of the electric telescopic rod 4, and the telescopic length of the first pipe 66 is greater than the stroke of the second screw 63. For example... Figure 5 As shown, the second pipe 610 and the first pipe 66 are telescopic pipes, which increases the stability of the device when adsorbing packaging bags.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
