AI Technical Summary
In existing technologies, small packaging bags are prone to standing on their side, tilting, or inverting during stacking, which reduces production efficiency. In particular, for strip-shaped packaging bags with an aspect ratio greater than 2:1, the upright rate is only 15%-20% when the stacking height exceeds 5 layers, requiring manual intervention for adjustment.
The device employs a rotary feeding mechanism and a double-layer stacking bin design. The rotary feeding mechanism stabilizes the falling of the packaging bags through rotating wheels and arc-shaped baffles, while the double-layer stacking bin achieves stable stacking of the packaging bags through synchronous control of the feeding plates, preventing them from standing on their sides or tilting, and improving feeding speed and efficiency.
It achieves stable stacking of packaging bags, reduces manual intervention, improves production efficiency and the neatness of packaging bags, and enhances the reliability of automated production.

TECHNICAL FIELD
[0001] The utility model relates to a kind of packaging machinery, specifically to a kind of packing production line for packing small packaging bag into carton. BACKGROUND
[0002] In the existing packaging industry, small packaging bags (such as independent small packaging of food, medicine) usually need to be stacked and packed into cartons or gift boxes through automatic assembly line. In the traditional process, the packaging bags are transported one by one by the conveying mechanism to the stacking bin for temporary storage. When the preset number is reached, the bottom of the stacking bin is opened, and the packaging bags are released in batches to complete the packaging in the carton. However, this technical solution has the following significant defects: when the packaging bags fall from the conveying mechanism into the stacking bin, due to the free falling inertia and the flexible characteristics of the bag body, it is easy to appear side standing, tilting or even inversion (especially for strip-shaped packaging bags with a length-width ratio greater than 2:1). Experimental data shows that when the stacking height exceeds 5 layers, the vertical standing rate of the packaging bags is as high as 15%-20%, which requires manual intervention and adjustment during subsequent carton packaging, reducing production efficiency. SUMMARY
[0003] In view of the deficiencies of the prior art, the utility model innovatively provides an automatic stacking packaging production line for improving stacking stability.
[0004] The automatic stacking packaging production line comprises a rack, a feeding conveying mechanism and a first stacking bin. The bottom of the first stacking bin has an openable first discharge plate. The first discharge plate is drivingly connected with a first material control power source that drives the first discharge plate to move. The feeding conveying mechanism is provided with a rotating discharge mechanism in front of the discharge end. The rotating discharge mechanism comprises a support, a rotating wheel and a rotating power source. The rotating wheel is rotatably mounted on the support, and the rotating power source is drivingly connected with the rotating wheel. A plurality of discharge grooves are circumferentially and equally arranged on the outer circumferential surface of the rotating wheel. An arc-shaped material blocking plate is connected to the support and located on the left or right side of the rotating wheel. The rotating wheel is located above the first stacking bin. The discharge end of the feeding conveying mechanism faces the discharge grooves of the rotating wheel.
[0005] The first stacking bin is provided with a second stacking bin below. The bottom of the second stacking bin has an openable second discharge plate. The second discharge plate is drivingly connected with a second material control power source that drives the second discharge plate to move.
[0006] The first discharge plate has two left and right ones. The two first discharge plates can be synchronously moved to open or close.
[0007] The second discharge plate has two left and right ones. The two second discharge plates can be synchronously moved to open or close.
[0008] The first stacked hopper has two first side baffles, one on the left and one on the right, which are mounted on a support.
[0009] The second stacking bin has two second side baffles, one on the left and one on the right, which are mounted on a support.
[0010] According to the automatic stacking packaging production line provided by this utility model, a rotating feeding mechanism is set between the feeding conveyor and the first stacking bin, so that the rotating feeding mechanism can smoothly and orderly lower the packaging bags into the first stacking bin, thereby achieving stable stacking of the packaging bags.

[0012] Figure 2 This is a partial structure of the present invention. Figure 1 ;
[0013] Figure 3 This is a partial structure of the present invention. Figure 2 . Detailed Implementation
[0014] like Figure 1 As shown, this automated stacking packaging production line includes a frame 1, a feeding conveyor mechanism 2, and a first stacking bin 4. The feeding conveyor mechanism 2 includes a conveyor belt; the bottom of the first stacking bin 4 has an openable first unloading plate 41, and the first unloading plate 41 is connected to a first material control power source 42 that drives the first unloading plate 41 to move.
[0015] To achieve stable material stacking, a rotating unloading mechanism 3 is provided in front of the discharge end of the feeding conveyor 2, such as... Figure 2 and Figure 3 As shown, the rotary feeding mechanism 3 includes a support 31, a rotating wheel 30, and a rotary power source 32. The support 31 is mounted on the frame 1, the rotating wheel 30 is rotatably mounted on the support 31, and the rotary power source 32 is connected to the rotating wheel 30 via a transmission connection. Driven by the rotary power source 32, the rotating wheel 30 rotates. Figure 3 As shown, a plurality of feeding troughs 300 are evenly distributed along the circumference on the outer surface of the rotating wheel 30. An arc-shaped baffle plate 33 is connected to the support 31. The arc-shaped baffle plate 33 is located on the left or right side of the rotating wheel 30 to prevent material from falling out of the feeding trough 300 when the feeding trough 300 rotates to the side. The rotating wheel 30 is located above the first stacking bin 4. The discharge end of the feeding conveying mechanism 2 faces the feeding trough 300 of the rotating wheel 30.
[0016] When working, the feeding conveying mechanism 2 conveys the packaging bags one by one forward, since the discharge end of the feeding conveying mechanism 2 faces the discharge grooves 300 of the rotating wheel 30, thus a packaging bag discharged from the feeding conveying mechanism 2 enters a discharge groove 300 of the rotating wheel 30, with the rotating wheel 30 rotating, the packaging bag enters the discharge grooves 300 of the rotating wheel 30 one by one, when the discharge groove 300 is located at the side, the arc-shaped material blocking plate 33 guards the discharge groove 300, and the packaging bag in the discharge groove 300 cannot fall out, when the discharge groove 300 comes to the lower side, since there is no arc-shaped material blocking plate 33 to block, the packaging bag in the discharge groove 300 falls into the first stacking bin 4 at the lower side, with the rotating wheel 30 rotating, the packaging bags fall into the first stacking bin 4 one by one to realize stacking, when the stacking reaches the set number of packaging bags, the first discharging plate 41 of the first stacking bin 4 is driven by the first material control power source 42 to move and open, thus the set number of packaging bags fall into the carton at the lower side. Since the packaging bags are discharged into the first stacking bin 4 by the rotating wheel 30 to realize stacking, the rotating wheel 30 plays a role of arranging and transferring, and the packaging bags cannot appear side-standing, tilting or even overturning when stacking, and the stacking is more neat.
[0017] If the set number of the packaging bags stacked in the first stacking bin 4 is larger (for example, 10), when the first discharging plate 41 moves and opens, the packaging bags cannot fall completely in a short time, thus it is required that the first stacking bin 4 stays for a certain time after opening, if the rotating speed of the rotating wheel 30 is faster, the discharging speed of the first stacking bin 4 and the discharging speed of the rotating wheel 30 cannot match, and if the rotating speed of the rotating wheel 30 is slowed down, the packaging efficiency is affected.
[0018] In order to solve the problem, the utility model further provides that a second stacking bin 5 is arranged below the first stacking bin 4, the bottom of the second stacking bin 5 is provided with an openable second discharging plate 51, the second discharging plate 51 is in transmission connection with a second material control power source 52 for driving the second discharging plate 51 to move. When the set number of the packaging bags to be stacked is 10, 5 packaging bags are stacked in the first stacking bin 4 first, then the first discharging plate 41 is controlled to open, so that the 5 packaging bags fall to the second stacking bin 5 to wait, and then 5 packaging bags are stacked in the first stacking bin 4 again, the first discharging plate 41 is controlled to open again, so that the last 5 packaging bags fall to the second stacking bin 5, and when the second stacking bin 5 is stacked with 10 packaging bags, the second discharging plate 51 is opened, so that the 10 packaging bags are discharged into the carton. Since the first stacking bin 4 only needs to control a small number of packaging bags to be discharged, the discharging speed is faster, and can match the rotating wheel 30 rotating fast.
[0019] In order to improve the discharging speed of the first stacking bin 4, the first discharging plate 41 has left and right two, and the two first discharging plates 41 can be synchronously moved to realize opening or closing. The two first discharging plates 41 can be controlled by two power sources respectively, or can be controlled by one power source.
[0020] Similarly, in order to improve the discharging speed of the second stacking bin 5, the second discharging plate 51 has left and right two, and the two second discharging plates 51 can be synchronously moved to realize opening or closing. The two second discharging plates 51 can be controlled by two power sources respectively, or can be controlled by one power source.
[0021] As shown in Figure 3 The first stacking bin 4 has left and right two first side baffles 40, and the first side baffles 40 are installed on the support 31. The two first side baffles 40 can be blocked on both sides of the packaging bag, and form the first stacking bin 4 with the first discharging plate 41.
[0022] The second stacking bin 5 has left and right two second side baffles 50, and the second side baffles 50 are installed on the support 31. The two second side baffles 50 can be blocked on both sides of the packaging bag, and form the second stacking bin 5 with the second discharging plate 51.
