[0002] Flat packaging bags are common in daily life, such as those used for plasters and ointments. These items are usually packaged in boxes along with instructions. Flat packaging bags are fed one by one onto a grid conveyor line using a feeding device, and then transported to the boxing station for packaging. Currently, typical flat packaging bag feeding devices include a storage bin, a suction mechanism, and a feeding mechanism. The storage bin holds stacked flat packaging bags, while the suction mechanism sucks the bags down one by one and places them on the feeding mechanism, which then delivers them to the grid conveyor line. However, flat packaging bags come in different sizes, requiring different types of storage bins. Currently, the size of storage bins on the market is generally not adjustable, necessitating the replacement of bins of different sizes when packaging materials, which is inconvenient.

Detailed Implementation

[0016] like Figure 1 As shown, this flat packaging bag unloading device includes a frame 1, a storage bin 2, a suction mechanism 3, and a feeding mechanism 4. The storage bin 2 is used to store flat packaging bags, the suction mechanism 3 is used to suck down the flat packaging bags one by one from the storage bin 2, and the feeding mechanism 4 is used to transport the sucked-down flat packaging bags forward.

[0017] like Figure 3 As shown, the frame 1 has a discharge port 10, and the storage bin 2 is installed on the frame 1 and communicates with the discharge port 10. Figure 1 As shown, the suction mechanism 3 is located below the storage bin 2, as... Figure 5 As shown, the suction mechanism 3 includes a suction nozzle 30 and a suction power source that drives the suction nozzle 30 to move up and down. The suction nozzle 30 is connected to a negative pressure source. Driven by the suction power source, the suction nozzle 30 can move upward and suck up a flat packaging bag at the bottom of the storage bin 2. Then the suction nozzle 30 moves downward and sucks down the flat packaging bag and places it on the feeding mechanism 4.

[0018] like Figure 2As shown, the feeding mechanism 4 includes a left conveyor belt unit 41 and a right conveyor belt unit 40. The suction mechanism 3 is located between the left conveyor belt unit 41 and the right conveyor belt unit 40 (i.e., the suction nozzle 30 is located between the left conveyor belt unit 41 and the right conveyor belt unit 40). The left conveyor belt unit 41 includes a left conveyor belt 412, a left front conveyor wheel 410, and a left rear conveyor wheel 411. The left conveyor belt 412 is wound around the left front conveyor wheel 410 and the left rear conveyor wheel 411. The right conveyor belt unit 40 includes a right conveyor belt 402, a right front conveyor wheel 400, and a right rear conveyor wheel 401. The right conveyor belt 402 is wound around the right front conveyor wheel 400 and the right rear conveyor wheel 401. A front rotating shaft 42 and a rear rotating shaft 401 are mounted on the frame 1. A rotating shaft 43 is used. The left front conveyor wheel 410 and the right front conveyor wheel 400 are mounted on the front rotating shaft 42. The left rear conveyor wheel 411 and the right rear conveyor wheel 401 are mounted on the rear rotating shaft 43. The front rotating shaft 42 or the rear rotating shaft 43 is connected to a feeding power source. Driven by the feeding power source, the front rotating shaft 42 or the rear rotating shaft 43 rotates, thus synchronously driving the left conveyor belt 412 and the right conveyor belt 402 to move. After the flat packaging bag is sucked down, it is placed on the left conveyor belt 412 and the right conveyor belt 402, which together transport the flat packaging bag forward. To facilitate adjustment of the distance between the left conveyor belt unit 41 and the right conveyor belt unit 40, and to meet the conveying needs of materials of different sizes, such as… Figure 2 As shown, a first adjusting plate 44, which can move axially, is installed on the front rotating shaft 42. The left front conveyor wheel 410 and the left rear conveyor wheel 411 are rotatably mounted on the first adjusting plate 44. The left front conveyor wheel 410 is splinedly connected to the front rotating shaft 42 (allowing the left front conveyor wheel 410 to move axially on the front rotating shaft 42, while also allowing the front rotating shaft 42 to drive the left front conveyor wheel 410 to rotate). The left rear conveyor wheel 411 is splinedly connected to the rear rotating shaft 43. A first adjusting screw 45 is rotatably mounted on the frame 1, and this first adjusting screw 45 is threadedly connected to the first adjusting plate 44. When it is necessary to adjust the distance between the left conveyor belt 412 and the right conveyor belt 402, simply rotating the first adjusting screw 45 will cause the first adjusting plate 44 to move along the axis of the front rotating shaft 42. This allows the first adjusting plate 44 to move the left front conveyor wheel 410 and the left rear conveyor wheel 411 together to one side, thus adjusting the distance between the left conveyor belt 412 and the right conveyor belt 402.

[0019] like Figure 3 and Figure 4As shown, the storage bin 2 includes a left bin plate 21, a right bin plate 20, a front bin plate 22, and a rear bin plate 23. The left bin plate 21 is mounted on a second adjusting plate 24. A left-right extending guide rail 13 is mounted on the frame 1. The second adjusting plate 24 is slidably mounted on the guide rail 13 via a slider 27. A second adjusting screw 26 is rotatably mounted on the frame 1, and the second adjusting screw 26 is threadedly connected to the second adjusting plate 24. When the size of the storage bin 2 needs to be adjusted, simply rotate the second adjusting screw 26. This causes the second adjusting plate 24 to move the left bin plate 21 to one side, thus adjusting the size of the storage bin 2. The storage bin 2 and the feeding mechanism 4 generally need to be adjusted simultaneously to meet the storage and conveying requirements of materials of different sizes.

[0020] like Figure 3 As shown, the bottom of the left storage compartment 21 is connected to a left support rod 210, the bottom of the right storage compartment 20 is connected to a right support rod, the bottom of the front storage compartment 22 is connected to a front support rod, and the bottom of the rear storage compartment 23 is connected to a rear support rod. The left support rod 210, right support rod, front support rod, and rear support rod form a support surface. After the material is placed in the storage compartment 2, the left support rod 210, right support rod, front support rod, and rear support rod support the material and prevent it from falling.

[0021] The storage bin is large on both sides, and as the material increases in size, the area required for support also increases accordingly. Therefore, the left support rod 210 is adjustable left and right and mounted on the left bin plate 21, the right support rod is adjustable left and right and mounted on the right bin plate 20, the front support rod is adjustable front and back and mounted on the front bin plate 22, and the rear support rod is adjustable front and back and mounted on the rear bin plate 23. By adjusting the positions of the four support rods, the support area for the material can be adjusted, thereby meeting the storage requirements of materials of different sizes.

[0022] like Figure 3 As shown, the front compartment plate 22 is connected to the front compartment plate base 220. The frame 1 has a front elongated hole 11. The front compartment plate base 220 is mounted on the frame 1 in a left-right adjustable manner by means of front bolts passing through the front elongated hole 11. This allows the left-right position of the front compartment plate 22 to be adjusted to accommodate the size adjustment of the storage bin 2. Similarly, the rear compartment plate 23 is connected to the rear compartment plate base 230. The frame 1 has a rear elongated hole 12. The rear compartment plate base 230 is mounted on the frame 1 in a left-right adjustable manner by means of rear bolts passing through the rear elongated hole 12. This allows the left-right position of the rear compartment plate 23 to be adjusted to accommodate the size adjustment of the storage bin 2.

[0023] In order to adjust the front and rear position of the rear compartment 23, such as Figure 3As shown, the rear compartment plate 23 is connected to the front and rear adjustment seat 25, which is connected to the rear compartment plate seat 230. The front and rear adjustment seat 25 has front and rear elongated holes 250 extending front and rear. The front and rear elongated holes 250 of the front and rear adjustment seat 25 and the rear elongated hole 12 of the frame 1 through which the rear bolt can pass can be adjusted.

[0024] like Figure 3 As shown, the left compartment plate 21 has a left elongated hole. The left compartment plate 21 is connected to the second adjusting plate 24 by a left bolt passing through the left elongated hole, so that the front and rear positions of the left compartment plate 21 can be adjusted.

[0025] The right compartment plate 20 has a right elongated hole. The right compartment plate 20 is connected to the frame 1 by a right bolt passing through the right elongated hole, so that the front and rear positions of the right compartment plate 20 can be adjusted.

[0026] like Figure 2 As shown, a passive conveyor wheel 46 is installed on the frame 1. The passive conveyor wheel 46 is located above both the left front conveyor wheel 410 and the right front conveyor wheel 400. When the material is conveyed out through the left conveyor belt 412 and the right conveyor belt 402, the passive conveyor wheel 46 can press down on the material when it is close to the front end, so that the material is smoothly conveyed to the grid conveyor line.

[0027] Finally, it is worth mentioning that the passive transmission wheel 46 is mounted on the passive wheel axle 47, as... Figure 2 As shown, the driven wheel axle 47 is connected to the lifting block 48. The frame 1 has a sliding groove 16, within which the lifting block 48 can slide vertically. A lifting adjustment screw 49 is rotatably mounted on the frame 1, located above the lifting block 48, and threadedly connected to it. By adjusting the lifting adjustment screw 49, the vertical position of the driven wheel axle 47 can be adjusted, thus accommodating the discharge of materials of different thicknesses.
