[0036] Specifically, the first rotary drive 122 drives the first rotating wheel 123 to rotate, and the first rotating wheel 123 drives the first rocker arm 125 to move back and forth in the first direction through the first connecting column 124. The first rocker arm 125 drives the first tapping piece 126 to move back and forth in the first direction, so that the first tapping piece 126 can tap the packaging bags located in the storage space 13 in the first direction. Since the rotation speed of the first rotary drive 122 is relatively fast, the first tapping piece 126 has a fast tapping speed, ensuring the neatness of the packaging bags in the storage space 13. Furthermore, the bag receiving bin 1 has a simple structure and low manufacturing cost.

The second rocker arm 145 is rotatably connected to the second striking member 146 at one end away from the second connecting post 144. The second striking member 146 and the back plate 112 are located on opposite sides of the bottom plate 113 along a second direction, and the storage space 13 is formed between the bottom plate 113, the back plate 112, the second striking member 146, the first side plate 111, and the first striking member 126. The second striking member 146 is used to align the packaging bags in the storage space 13 along the second direction; wherein, the first direction is perpendicular to the second direction. It can be understood that the second striking member 146 and the back plate 112 are respectively located on the front and rear sides of the storage space 13, and the second rotary drive member 142 includes, but is not limited to, a motor.

[0039] Specifically, the second rotary drive 142 drives the second rotating wheel 143 to rotate. The second rotating wheel 143 drives the second rocker arm 145 to move back and forth in the second direction via the second connecting column 144. The second rocker arm 145 drives the second striking member 146 to move back and forth in the second direction, so that the second striking member 146 can align the packaging bags located in the storage space 13 in the second direction. Since the rotation speed of the second rotary drive 142 is relatively fast, the second striking member 146 has a fast aligning speed, ensuring the neatness of the packaging bags in the storage space 13. In this embodiment, the first striking member 126 can align the packaging bags in the storage space 13 in the first direction, and the second striking member 146 can align the packaging bags in the storage space 13 in the second direction, further ensuring the neatness of the packaging bags in the storage space 13.

[0040] In one embodiment, such as Figure 1 As shown, the front-mounted assembly 14 further includes a second guide rail and a second slider. The second guide rail is mounted on the second support base 141, and the second slider is mounted on the second rocker arm 145 and slidably connected to the second guide rail. Specifically, during the reciprocating movement of the second rocker arm 145 in the second direction, the second rocker arm 145 slides on the second guide rail via the second slider, thereby ensuring the stability of the movement of the second rocker arm 145 in the second direction.

[0041] In one embodiment, such as Figure 1 and Figure 4 As shown, the second rocker arm 146 includes a first support block 1461 and a plurality of first forks 1462 spaced apart on the first support block 1461. A first through hole is provided between two adjacent first forks 1462. The end of the second rocker arm 145 away from the second connecting post 144 is connected to the first support block 1461. It can be understood that the first support block 1461 and the first forks 1462 constitute a fork-type structure.

[0042] The bag receiving hopper 1 further includes a receiving assembly 15, which includes a moving drive component 151, a second support block 152, and a plurality of second forks 153 spaced apart on the second support block 152. A second through hole is provided between two adjacent second forks 153. The ends of the first forks 1462 away from the first support block 1461 pass through the second through holes, and the ends of the second forks 153 away from the second support block 152 pass through the first through holes. The moving drive component 151 is connected to the second support block 152 and is used to drive the second support block 152 and the second forks 153 to move along a second direction. It can be understood that the moving drive component 151 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and linear motors, etc., and the second forks 153 are located above the base plate 113.

[0043] Specifically, the second fork 153 is located in the storage space 13. The second fork 153 can support the packaging bags in the storage space 13 from the bottom. When a preset number of packaging bags are stored on the second fork 153, the moving drive 151 drives the second fork 153 out of the storage space 13 through the second support block 152. The packaging bags on the second fork 153 will fall onto the base plate 113, thereby avoiding the accident of the packaging bags falling too high at once and overturning, and further ensuring the neatness of the packaging bags in the storage space 13.

[0044] In one embodiment, such as Figure 1 As shown, the bag receiving hopper 1 further includes a first alignment drive 16 mounted on the first support base 121 and a second side plate 17 mounted on the output end of the first alignment drive 16. The first side plate 111 and the second side plate 17 are located on opposite sides of the base plate 113 along a first direction. The first alignment drive 16 is used to drive the second side plate 17 to move along the first direction. It can be understood that the first alignment drive 16 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, and a linear motor.

[0045] Specifically, when the first aligning drive 16 drives the second side plate 17 away from the first side plate 111, the first aligning member 126 then aligns the packaging bag in the storage space 13 along the first direction. When the first aligning drive 16 drives the second side plate 17 closer to the first side plate 111, the moving drive 151 then drives the second fork 153 out of the storage space 13 via the second support block 152. The packaging bag on the second fork 153 will fall onto the bottom plate 113. During the process of the packaging bag falling onto the bottom plate 113, the packaging bag abuts against the first side plate 111 and the second side plate 17 on opposite sides along the first direction, thereby ensuring the stability of the packaging bag falling onto the bottom plate 113.

[0046] In one embodiment, such as Figure 1 As shown, the first side plate 111 has a first guide portion on the side away from the back plate 112, and the first abutting member 126 has a second guide portion on the side away from the back plate 112; the first guide portion and the second guide portion are used to guide the packaging bag into the storage space 13. Understandably, the first guide portion and the second guide portion form a figure-eight shaped guide inlet, allowing the packaging bag to enter the storage space 13 along the first guide portion and the second guide portion, ensuring the stability of the packaging bag as it falls into the storage space 13.

[0047] like Figure 5 and Figure 6 As shown, another embodiment of this utility model also provides a strapping mechanism, including a base 2, a transfer robot 3, a strapping assembly 4, and the aforementioned bag receiving bin 1; the first support base 121, the first side plate 111, the back plate 112, the bottom plate 113, the transfer robot 3, and the strapping assembly 4 are all mounted on the base 2; the transfer robot 3 is used to grab a stack of packaging bags in the storage space 13 and place them on the strapping assembly 4; the strapping assembly is used to strap a stack of packaging bags.

[0048] Specifically, the conveyor line transports the packaging bags one by one to the storage space 13. When the storage space 13 contains a preset number of packaging bags, the transfer robot 3 picks up a stack of packaging bags from the storage space 13 and transports them to the strapping assembly 4. The strapping assembly 4 then straps the stack of packaging bags together with strapping components (straps, tape, etc.). In this invention, the strapping mechanism can automatically complete the strapping of the packaging bags, improving the automation efficiency of the strapping mechanism.

[0049] In one embodiment, such as Figure 5 and Figure 6As shown, the strapping mechanism also includes a sensing component (not shown) and a lifting drive component 5. The sensing component is used to detect the height of the packaging bag in the storage space 13; the lifting drive component 5 is used to drive the base 2 to rise and fall. Understandably, the lifting drive component 5 includes, but is not limited to, a lead screw and nut assembly, a pneumatic cylinder, and a hydraulic cylinder. The sensing component includes a transmitting sensor and a receiving sensor spaced apart along a first direction. When the height of the packaging bag in the storage space 13 is lower than a first preset height, the laser emitted by the transmitting sensor can be received by the receiving sensor. When the height of the packaging bag in the storage space 13 is equal to or higher than the first preset height, the laser emitted by the transmitting sensor cannot be received by the receiving sensor. The lifting drive component 5 then drives the bag receiving hopper 1 to descend via the base 2, allowing the bag receiving hopper 1 to stably receive the packaging bag. In this embodiment, the design of the sensing component and the lifting drive component 5 reduces the height from which the packaging bag falls into the storage space 13.

[0050] In one embodiment, such as Figure 5 and Figure 6 As shown, the strapping mechanism also includes a conveying assembly 6 mounted on the base 2; the transfer robot 3 is also used to convey a stack of packaged bags that have been strapped on the strapping assembly 4 to the conveying assembly 6. Understandably, the conveying assembly 6 includes, but is not limited to, a conveyor belt, etc., and can convey bundles of packaged bags, further improving the automation level of the strapping mechanism.

[0051] Another embodiment of this utility model provides a bag sorting robot, including a detection component, a waste discharge component, a conveying assembly line, and the aforementioned strapping mechanism;

[0052] The conveyor line is used to transport packaging bags one by one into the storage space 13; the detection component is used to detect whether the packaging bags on the conveyor line are qualified; the waste removal component is installed on the conveyor line to remove unqualified packaging bags. Understandably, the detection component includes, but is not limited to, a detection camera, etc., and the detection component can detect whether the appearance of the packaging bags on the conveyor line is qualified; the conveyor line includes, but is not limited to, a conveyor belt, etc., and the conveyor line can transport packaging bags one by one into the storage space 13 along a second direction.

[0053] Specifically, when the detection component detects that the packaging bag on the conveyor line is a qualified product, the waste discharge component does not operate, and the conveyor line transports the qualified packaging bag on it to the storage space 13; when the detection component detects that the packaging bag on the conveyor line is a defective product, the waste discharge component operates and removes the defective packaging bag from the conveyor line.

[0054] The above are merely embodiments of the bag receiving hopper, the strapping mechanism, and the bag sorting robot, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
