[0002] With the continuous development of the economy, food and vegetables are no longer simply used to meet people's own needs; they can also be packaged in bags and sold to other consumers.

[0003] Automatic bag sorting equipment, as an automated device that can automatically inspect each packaging bag, can remove unqualified bags and finally stack and bundle the qualified bags. Automatic bag sorting equipment ensures the quality of packaging bags and greatly reduces the cost of manual bag inspection. The conveying mechanism is located at the front end of the automatic bag sorting machine. This mechanism receives the packaging bags from the bag-making machine one by one and transports them to the rear end.

The first lifting drive 42 is installed at the output end of the first swivel drive 41. The swivel assembly 4 is used to adsorb the packaging bag 100 and, after adjusting it to a preset angle, place it on the first lower conveyor belt assembly 1 between the first conveying channel 23 and the second conveying channel 33.

[0023] The first guide component 2 is located in front of the rotation component 4, and the second component is located behind the rotation component 4.

[0024] Specifically, during the process of the first lower conveyor belt assembly 1 conveying the packaging bags 100 one by one along the first direction, the packaging bags 100 first enter the first conveying channel 23, where the first side plate 21 and the second side plate 22 abut against the opposite ends of the packaging bags 100 from the length direction; the packaging bags 100 in the first conveying channel 23 are conveyed to the bottom of the rotating assembly 4, the first lifting drive 42 drives the adsorption assembly 43 to move down, after the adsorption assembly 43 adsorbs the packaging bags 100 on the first lower conveyor belt assembly 1, the first rotating drive 41 drives the first lifting drive 42 and the adsorption assembly 43 to rotate 90 degrees, and the packaging bags 100 are rotated 90 degrees and then placed on the first lower conveyor belt assembly 1; the packaging bags 100 are conveyed to the second conveying channel 33, where the third side plate 31 and the fourth side plate 32 abut against the opposite ends of the packaging bags 100 along the width direction, and the packaging bags 100 in the second conveying channel 33 are then conveyed to the rear end. In this utility model, the swivel component 4 can adjust the direction of the packaging bag 100 on the first lower conveyor belt component 1, so that the second guide component 3 can guide the packaging bag 100 along the width direction. When the second guide component 3 and the packaging bag 100 abut against each other on opposite sides along the width direction, the packaging bag 100 is less likely to tilt or bulge, ensuring the flatness of the packaging bag 100 conveyed backward by the second conveying channel 33, and improving the smoothness of the rotary conveying mechanism in conveying the packaging bag 100.

[0025] In one embodiment, such as Figure 3 and Figure 4 As shown, the rotary conveying mechanism further includes a first bag pressing assembly 5; the first bag pressing assembly 5 includes a first carrier plate 51, a first pressing belt 52, and a first pulley 53 and a second pulley 54 spaced apart on the first carrier plate 51 along a first direction, the first pressing belt 52 being wound around the first pulley 53 and the second pulley 54; the first bag pressing assembly 5 is disposed in the first conveying channel 23, located above the first lower conveyor belt assembly 1, and is used to press the packaging bags 100 in the first conveying channel 23; The rotary conveying mechanism further includes a second bag pressing assembly 6; the second bag pressing assembly 6 includes a second carrier plate 61, a second pressing belt 62, and a third pulley 63 and a fourth pulley 64 spaced apart on the second carrier plate 61 along a first direction, the second pressing belt 62 being wound around the third pulley 63 and the fourth pulley 64; the second bag pressing assembly 6 is disposed in the second conveying channel 33, located above the first lower conveyor belt assembly 1, and is used to press the packaging bags 100 in the second conveying channel 33.

[0027] In this embodiment, during the process of the first lower conveyor belt assembly 1 conveying the packaging bag 100 in the first conveying channel 23, the first pressure belt 52 can press down the packaging bag 100 in the first conveying channel 23 to prevent the packaging bag 100 from tilting or bulging, thus ensuring the stability of the packaging bag 100 moving in the first conveying channel 23; during the process of the first lower conveyor belt assembly 1 conveying the packaging bag 100 in the second conveying channel 33, the second pressure belt 62 can press down the packaging bag 100 in the second conveying channel 33 to prevent the packaging bag 100 from tilting or bulging, thus ensuring the stability of the packaging bag 100 moving in the second conveying channel 33.

[0028] In one embodiment, such as Figure 4 As shown, the rotary conveying mechanism includes a blocking component 7 disposed below the first lower conveyor belt assembly 1. The blocking component 7 includes a second lifting drive and a stop block installed at the output end of the second lifting drive. The second lifting drive is used to drive the stop block to rise and fall, so that the stop block blocks the packaging bag 100 on the first lower conveyor belt assembly 1. The swivel component 4 is used to adsorb the packaging bag 100 blocked by the stop.

[0029] The second lifting drive component includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and linear motors.

[0030] Specifically, when the second lifting drive unit drives the stop block to move upward, the stop block can prevent the packaging bag 100 from moving backward on the first lower conveyor belt assembly 1. That is, the stop block can block the packaging bag directly below the rotating assembly 4. The rotating assembly 4 can accurately pick up the packaging bag 100 and rotate it by a preset angle.

[0031] In one embodiment, such as Figure 3 As shown, a first guide channel 24 is also provided between the first side plate 21 and the second side plate 22. The first guide channel 24 connects to the end of the first conveying channel 23 away from the second conveying channel 33. From the end close to the first conveying channel 23 toward the end away from the first conveying channel 23, the width of the first guide channel 24 gradually increases along the second direction.

[0032] The first guide channel 24 is located at the front end of the first conveying channel 23. The first guide channel 24 can be a figure-eight shaped guide groove. The first guide channel 24 can guide the packaging bag 100 to the first conveying channel 23, ensuring the smooth entry of the packaging bag 100 into the first conveying channel 23.

[0033] In one embodiment, such as Figure 3 As shown, a second guide channel 34 is also provided between the third side plate 31 and the fourth side plate 32. The second guide channel 34 connects to the end of the second conveying channel 33 that is close to the first conveying channel 23. From the end close to the second conveying channel 33 toward the end away from the second conveying channel 33, the width of the second guide channel 34 gradually increases along the second direction. The second guide channel 34 is located at the front end of the second conveying channel 33. The second guide channel 34 can be a figure-eight shaped guide groove. The second guide channel 34 can guide the packaging bag 100 to the second conveying channel 33, ensuring the smooth entry of the packaging bag 100 into the second conveying channel 33.

[0034] In one embodiment, such as Figure 3 As shown, along the second direction, the width of the first conveying channel 23 is greater than the width of the second conveying channel 33. In this embodiment, the first side plate 21 and the second side plate 22 of the wider first conveying channel 23 can guide the packaging bag 100 in the length direction; the third side plate 31 and the fourth side plate 32 of the narrower second conveying channel 33 can guide the packaging bag 100 in the width direction.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the rotary conveying mechanism further includes a support assembly 8, which includes a support base 81 and a first support frame 82, a second support frame 83 and a third support frame 84 that are spaced apart on the support base 81 along a first direction. The first lower conveyor belt assembly 1 is mounted on the support base 81, the first side plate 21 and the second side plate 22 are both mounted on the first support frame 82, the first rotary drive component 41 is mounted on the second support frame 83, and the third side plate 31 and the fourth side plate 32 are both mounted on the third support frame 84.

[0036] Among them, the first guide assembly 2 is supported above the first lower conveyor belt assembly 1 by the first support frame 82, the swivel assembly 4 is supported above the first lower conveyor belt assembly 1 by the second support frame 83, and the second guide assembly 3 is supported above the first lower conveyor belt assembly 1 by the third support frame 84; furthermore, the first bag pressing assembly 5 is supported above the first lower conveyor belt assembly 1 by the fourth support frame, the second bag pressing assembly 6 is supported above the first lower conveyor belt assembly 1 by the fifth support frame, and the blocking assembly 7 is supported below the first lower conveyor belt assembly 1 by the sixth support frame.

[0037] In one embodiment, such as Figure 4 As shown, the first lower conveyor belt assembly 1 includes a first support plate 11, a second rotary drive 12, a first belt roller 13, a second belt roller 14, and a first conveyor belt 15 wound on the first belt roller 13 and the second belt roller 14. The first belt roller 13 and the second belt roller 14 are rotatably mounted on the support base 81 at intervals along a first direction. The output end of the second rotary drive 12 is connected to the second belt roller 14. The first support plate 11 is disposed between the upper and lower sections of the first conveyor belt 15.

[0038] The second rotary drive component 12 includes, but is not limited to, a motor, a belt assembly, etc.

[0039] Specifically, the second rotary drive 12 drives the second belt roller 14 to rotate, and the second belt roller 14 can drive the first conveyor belt 15 to move, so that the first conveyor belt 15 can drive the packaging bag 100 on it to move along the first direction; since the width of the first conveyor belt 15 is small and the material of the first conveyor belt 15 is relatively soft, the first support plate 11 can support the packaging bag 100 from below, ensuring the stability of the first conveyor belt 15 in conveying the packaging bag 100.

[0040] In one embodiment, such as Figure 4 As shown, the rotary conveying mechanism further includes an inlet guide assembly 9, which includes a first gear 91, a second gear 92, a first guide wheel 93, a second guide wheel 94, and a first guide rod 95 rotatably mounted on the support base 81.

The first guide wheel 93 and the second guide wheel 94 rotate in opposite directions and are used to guide the packaging bag 100 to the first conveying channel 23.

[0041] The inlet guide assembly 9 is located at the front end of the first lower conveyor belt assembly 1; the first guide rod 95 is located above the first belt roller 13; and a gap is provided between the first guide wheel 93 and the second guide wheel 94 for a single packaging bag 100 to move.

[0042] Specifically, the second rotary drive 12 can drive the first belt roller 13 to rotate through the second belt roller 14 and the first conveyor belt 15. The first belt roller 13 drives the first guide wheel 93 to rotate through the meshing first gear 91 and second gear 92. The rotation directions of the first belt roller 13 and the first guide rod 95 are opposite. Since the first guide wheel 93 is mounted on the first guide rod 95 and the second guide wheel 94 is mounted on the first belt roller 13, the rotation directions of the first guide wheel 93 and the second guide wheel 94 are opposite. Thus, the first guide wheel 93 and the second guide wheel 94 can press the single packaging bag 100 into the first conveying channel 23, ensuring the smoothness of the packaging bag 100 entering the first conveying channel 23.

[0043] In this embodiment, the first lower conveyor belt assembly 1 and the inlet guide assembly 9 can share a second rotary drive 12, which improves the compactness of the rotary conveying mechanism and reduces the manufacturing cost of the rotary conveying mechanism.

[0044] In one embodiment, such as Figure 1 and Figure 3 As shown, the rotary conveying mechanism also includes a detection element 10 and a waste removal component 20, both mounted on the support base 81. The detection element 10 is used to detect whether the packaging bag 100 in the second conveying channel 33 is a qualified product, and the waste removal component 20 is used to remove unqualified packaging bags 100 from the second conveying channel 33.

[0045] Among them, the detection component 10 includes, but is not limited to, a vision camera, etc. The waste discharge component 20 can remove unqualified packaging bags 100 from the second conveying channel 33 by means of adsorption, clamping, etc., to ensure that the rotary conveying mechanism conveys only qualified packaging bags 100.

[0046] In one embodiment, such as Figure 1 , Figure 4 as well as Figure 5As shown, the rotary conveying mechanism further includes a second lower conveyor belt assembly 30, which includes a second support plate 301, a third belt roller 302, a fourth belt roller 303, and a second conveyor belt 304 wound around the third belt roller 302 and the fourth belt roller 303. The third belt roller 302 and the fourth belt roller 303 are rotatably mounted on the support base 81 at intervals along a first direction. A waste discharge channel 305 is provided between the first conveyor belt 15 and the second conveyor belt 304. The second support plate 301 is disposed between the upper and lower sections of the second conveyor belt 304. The waste discharge component 20 is used to push the unqualified packaging bag 100 in the second conveying channel 33 to the waste discharge channel 305; The rotary conveying mechanism further includes a transmission assembly 40, which includes a third gear 401, a fourth gear 402, and a transmission belt 403 wound around the third gear 401 and the fourth gear 402. The third gear 401 is mounted on the third belt roller 302, and the fourth gear 402 is mounted on the fourth belt roller 303. The third gear 401 meshes with the fourth gear 402.

[0047] The waste discharge channel 305 is connected to the bottom of the second conveying channel 33. Since the width of the second conveyor belt 304 is small and the material of the second conveyor belt 304 is relatively soft, the second support plate 301 can support the packaging bag 100 from below, ensuring the stability of the second conveyor belt 304 in conveying the packaging bag 100.

[0048] Specifically, the second belt roller 14 can drive the third belt roller 302 to rotate through the meshing third gear 401 and fourth gear 402, and the third belt roller 302 can drive the second conveyor belt 304 to move, so that the second conveyor belt 304 can move the packaging bag 100 along the first direction; the first lower conveyor belt assembly 1, the second lower conveyor belt assembly 30, and the inlet guide assembly 9 can share a second rotary drive 12, which further improves the compactness of the rotary conveying mechanism and reduces the manufacturing cost of the rotary conveying mechanism.

[0049] When the detection component 10 detects a defective product on the packaging platform of the first lower conveyor belt assembly 1, one end of the packaging bag 100 is moved to the top of the waste discharge channel 305.
