Description

Technical Field

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

[0002] In existing technologies, packaging bags are usually stored and transported in an unopened, flat state to reduce their footprint. To open them for filling, a robotic arm is typically used to pick them up and transport them to a conveyor platform, where a conveyor belt further propels them forward. However, when transported solely by a conveyor belt, the packaging bags are prone to deviation, leading to discrepancies when opening the boxes later. Some feeding mechanisms use suction nozzles to pick up the packaging bags during feeding to prevent deviation. However, suction nozzles require air suction devices, which are cumbersome to assemble and have relatively high energy consumption. Furthermore, they cannot be used when the material is non-woven fabric, limiting their application. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a packaging bag feeding mechanism that uses a gripper to hold the packaging bag and uses a synchronous belt to transport the gripper forward, thereby realizing the feeding of the packaging bag. This can prevent the packaging bag from shifting, reduce energy consumption, and has stronger applicability.

[0004] This utility model discloses a packaging bag feeding mechanism, including a frame, a platform on the frame, and a transport component for transporting packaging bags on the platform. The transport component includes grippers for holding the packaging bags and a conveyor belt for driving the grippers back and forth. The grippers are arranged in at least two sets at intervals. Support rails are provided on the frame corresponding to the positions of each set of grippers. Mounting frames are guided and slidable on the support rails. Each set of grippers is mounted on a corresponding mounting frame, and one side of the mounting frame is fixed to the conveyor belt.

[0005] A further feature of this invention is that each set of grippers includes a support block, a movable block that can extend relative to and cooperate with the support block to form a gripping action, and a driving component that drives the movable block to extend or retract. It also includes a rocker arm, a first connecting rod, and a second connecting rod. One end of the rocker arm is hinged to the mounting frame, and the other end is hinged to the movable block. One end of the first connecting rod is hinged to the output shaft of the driving component, and the other end is hinged to the rocker arm. One end of the second connecting rod is hinged to the output shaft of the driving component, and the other end is hinged to the movable block. The rocker arm, the first connecting rod, the second connecting rod, and the movable block cooperate to form a telescopic four-bar linkage structure.

[0006] A further feature of this invention is that the mounting frame is provided with a dovetail groove along the length of the support rail, and the support rail portion is inserted into the dovetail groove and adapted to it, forming a support and anti-detachment structure for the mounting frame.

[0007] A further feature of this invention is that an anti-slip block is detachably connected to one side of the movable block that cooperates with the support block.

[0008] A further feature of the utility model is that the top of the support block is also provided with anti-slip texture.

[0009] A further feature of this invention is that a tension roller is provided on the frame corresponding to the position of the conveyor belt, the tension roller swing adjustment is on the frame, and a locking element is also included to lock the tension roller after it swings.

[0010] The beneficial effects of this utility model are as follows: When in use, the two sets of grippers can clamp the packaging bag in a balanced manner, and then the support rail prevents the grippers from shifting. Furthermore, the conveyor belt transports the bag, causing the grippers to slide and thus transporting the bag. The mounting frame facilitates the installation of the grippers and also facilitates the stable sliding of the grippers. It has a wide range of requirements for the material of the packaging bag, and can be used for cardboard, non-woven fabric, plastic sheets, etc. Attached Figure Description

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] This utility model discloses a packaging bag feeding mechanism, including a frame 1, a platform 2 mounted on the frame 1, and a transport component 3 for transporting packaging bags on the platform 2. In this utility model embodiment, the transport component 3 includes grippers 31 for clamping the packaging bags and a conveyor belt 32 for driving the grippers 31 to move back and forth (the conveyor belt 32 is common knowledge and will not be described in detail here). The grippers 31 are arranged in at least two sets at intervals. A support rail 4 is provided on the frame 1 corresponding to each set of grippers 31. A mounting frame 5 is guided and slidably mounted on the support rail 4. Each set of grippers 31 is mounted on the corresponding mounting frame 5, and one side of the mounting frame 5 is fixed to the conveyor belt 32.

[0019] Using the above technical solution, when in use, the two sets of grippers 31 can clamp the packaging bag in a balanced and stable manner. Then, the support rail 4 prevents the grippers 31 from shifting. The bag is further transported by the conveyor belt 32, which drives the grippers 31 to slide, thereby transporting the packaging bag. The mounting frame 5 facilitates the installation of the grippers 31 and also facilitates the stable sliding of the grippers 31. It has a wide range of requirements for the material of the packaging bag, and cardboard, non-woven fabric, plastic sheet, etc. can all be used.

[0020] Each set of grippers 31 includes a support block 6, a movable block 7 that can extend relative to the support block 6 to cooperate with it to form a gripping action, and a driving component 8 (preferably a telescopic cylinder or electric cylinder, but can also be a motor) that drives the movable block 7 to extend or retract. It also includes a swing rod 9, a first connecting rod 10, and a second connecting rod 20. One end of the swing rod 9 is hinged to the mounting frame 5, and the other end is hinged to the movable block 7. One end of the first connecting rod 10 is hinged to the output shaft of the driving component 8, and the other end is hinged to the swing rod 9. One end of the second connecting rod 20 is hinged to the output shaft of the driving component 8, and the other end is hinged to the movable block 7. The swing rod 9, the first connecting rod 10, the second connecting rod 20, and the movable block 7 cooperate to form a telescopic four-bar linkage structure. When the driving component 8 drives the first connecting rod 10 and the second connecting rod 20 to extend or retract, it can drive the swing rod 9 to move, so that the movable block 7 can move in the up and down and back and forth directions, thereby achieving the gripping or releasing of the packaging bag.

[0021] The mounting frame 5 is provided with a dovetail groove 30 arranged along the length of the support rail 4. The support rail 4 is partially inserted into the dovetail groove 30 and adapted to it, forming a support and anti-detachment structure for the mounting frame 5. The dovetail groove 30 can achieve both guiding and anti-detachment effects at the same time, making it more practical.

[0022] The movable block 7 is detachably connected to the side that cooperates with the support block 6 with an anti-slip block 40, which can more stably drive the packaging bag for transportation. The anti-slip block 40 can be a serrated block or a rubber block, etc., to increase friction. The specific connection method can be to use bolts for connection.

[0023] The top of the support block 6 is also provided with anti-slip texture 50, which further increases the friction, prevents the packaging bag from shifting, and can more stably drive the packaging bag for transportation. The anti-slip texture 50 is preferably composed of several raised anti-slip strips, and the anti-slip strips can also be in the shape of reverse teeth.

[0024] The frame 1 is also equipped with a tension roller 60 at the position corresponding to the conveyor belt 32. The tension roller 60 swings and is adjusted on the frame 1. It also includes a locking component (not shown in the figure) that locks the tension roller 60 after it swings. This allows for adjustment of the tension of the conveyor belt 32, making adjustment more convenient. The locking component is preferably a bolt.
