Description

Technical Field

[0001] This utility model relates to a hanging and pushing mechanism for a soft-handled packaging bag. Background Technology

[0002] Currently, common rice packaging bags include snap-on bags and ordinary laminated woven bags. Therefore, conventional semi-automatic or fully automatic packaging machines are designed around these two types of bags. In existing technology, while fully automatic rice packaging equipment is relatively mature, it is not compatible with soft-handle bags when using them for packaging. This invention was developed to adapt to the storage and handling functions of soft-handle bags. Utility Model Content

[0003] This utility model improves upon the above-mentioned problems by providing a hanging and pushing mechanism for soft-handled packaging bags, which is simple in structure and easy to use.

[0004] This utility model is constructed as follows: it includes a bag hanging mechanism for suspending multiple soft-handled packaging bags, and a bag pushing mechanism is provided above the bag hanging mechanism to press down on the soft-handled packaging bags, so that the soft-handled packaging bags on the bag hanging mechanism are kept in a position near the outer end of the bag hanging mechanism.

[0005] Furthermore, the bag-hanging mechanism includes a bag-hanging frame, a bag-hanging mounting base plate, and at least two bag-hanging rods spaced apart on the bag-hanging mounting base plate, one of which corresponds to the bag-pushing mechanism. The bag-hanging frame and the bag-hanging mounting base plate are connected via a bag-hanging sliding assembly. A bag-hanging switching cylinder is provided below the bag-hanging mounting base plate to drive the bag-hanging mounting base plate and the bag-hanging rods to move. When the soft-handled packaging bags on one bag-hanging rod are used up, the soft-handled packaging bags on the other bag-hanging rod are switched to move to the position of the bag-pushing mechanism. The bag-hanging switching cylinder is connected to the bag-hanging mounting base plate via a bag-hanging switching cylinder lug.

[0006] Furthermore, the bag hanging sliding assembly includes a bag hanging slider disposed behind the bag hanging mounting base plate, and a bag hanging slide rail is disposed on the side of the bag hanging frame near the bag hanging slider, and the bag hanging slider slides in cooperation with the bag hanging slide rail.

[0007] Furthermore, a bag-hanging brush is provided near the outer end of the bag-hanging rod.

[0008] Furthermore, the bag-hanging rod includes two spaced-apart straight rods, with arc-shaped blocks at the outer ends of the two straight rods, and the inner ends of the two straight rods are connected to the bag-hanging mounting base plate.

[0009] Furthermore, the bag pushing mechanism includes a bag pushing machine base, a lifting and pushing bag module, and a bag pushing cylinder. The lifting and pushing bag module is slidably engaged with the bag pushing machine base via a bag pushing sliding assembly. The bag pushing cylinder is used to drive the lifting and pushing bag module to move along the length direction of the bag pushing mechanism.

[0010] Furthermore, the lifting and pushing bag module includes a pushing bag cylinder fixing plate, a guide shaft mounting seat, a lifting guide shaft, and a pushing bag plate arranged sequentially from top to bottom. The upper end of the lifting guide shaft is slidably engaged with a linear bearing mounted on the guide shaft mounting seat, and the lower end of the lifting guide shaft is connected to the pushing bag plate. Pushing bag lifting cylinders for driving the pushing bag plate to rise and fall are provided on both sides of the guide shaft mounting seat. An avoidance groove is provided at the lower part of the pushing bag plate.

[0011] Furthermore, one end of the push-bag cylinder is connected to the lower part of one side of the push-bag cylinder, and the telescopic end of the push-bag cylinder is connected to the push-bag cylinder fixing plate via the push-bag cylinder connecting seat.

[0012] Furthermore, the guide shaft mounting base is provided with bag-pushing lifting cylinder seats on both sides, and the bag-pushing cylinder is fixed on the bag-pushing lifting seat.

[0013] Furthermore, the bag pushing sliding assembly includes a bag pushing slider disposed on the bag pushing cylinder fixing plate and a bag pushing slide rail disposed below the bag pushing machine base, wherein the bag pushing slider and the bag pushing slide rail are slidably engaged.

[0014] Compared with the prior art, this utility model has the following advantages: The device has a simple structure, reasonable design, and is easy to use. It involves attaching the outer soft handle of the soft-handled packaging bag to two hanging rods, one of which corresponds to the working position of the bag-pushing mechanism. After the worker completes the bag-hanging work, the bag-pushing cylinder of the bag-pushing mechanism extends to its longest position, driving the bag-pushing plate downwards so that it is positioned behind the last soft-handled packaging bag. Then, the bag-pushing cylinder retracts, and the bag-pushing plate pushes the soft-handled packaging bag hanging on the bag-pushing rod towards the hanging rod near the hanging brush, until the outer soft handle of the foremost soft-handled packaging bag is moved as close as possible to the hanging brush position at the outer end of the hanging rod. This system confines all soft-handled bags between the bag-hanging brush and the bag-pushing plate. As the first soft-handled bag is removed, the bag-pushing plate gradually moves closer to the bag-hanging brush, ensuring that a soft-handled bag is always in contact with the brush for easy bag retrieval. When a bag-hanging bar is empty, the bag-pushing mechanism resets, and the bag-hanging switching cylinder drives the bag-hanging mounting plate and the bag-hanging bar to move away from the bag-pushing mechanism. Meanwhile, another bag-hanging bar full of soft-handled bags moves to the push-bag mechanism's position, thus achieving the bag-hanging bar switching function and replacing it with a new bag-full bar to continue retrieval.

[0022] The aforementioned soft-handle packaging bag A3 includes a bag body A31 and soft handles located on both sides of the bag body. One soft handle is the outer soft handle A32, and the other soft handle is the inner soft handle A33. The outer soft handle is suspended on the bag hanging rod of the bag hanging mechanism, while the inner soft handle is not suspended on the bag hanging rod and generally hangs down naturally. The bag hanging requirement is that only the outer soft handle is hung, and the inner soft handle must be ensured to hang down. The two soft handles of the packaging bags should not be stacked as much as possible.

[0023] In this embodiment of the utility model, the bag hanging mechanism A1 includes a bag hanging frame A101, a bag hanging mounting base plate A102, and at least two bag hanging rods A103 spaced apart on the bag hanging mounting base plate. One bag hanging rod corresponds to the bag pushing mechanism. The bag hanging frame and the bag hanging mounting base plate are connected by a bag hanging sliding assembly A104. A bag hanging switching cylinder A105 is provided below the bag hanging mounting base plate to drive the bag hanging base plate and the bag hanging rods to move. When the soft handle packaging bag on one bag hanging rod is used up, the soft handle packaging bag on the other hanging rod is switched to move to the position of the bag pushing mechanism. The bag hanging switching cylinder is connected to the bag hanging mounting base plate by a bag hanging switching cylinder ear seat A106. The bag hanging switching cylinder ear seat is installed on the bag hanging mounting base plate, and the output shaft of the bag hanging switching cylinder is hinged to the bag hanging switching cylinder ear seat.

[0024] In this embodiment of the utility model, the bag hanging sliding assembly A104 includes a bag hanging slider A1041 disposed behind the bag hanging mounting base plate, and a bag hanging slide rail A1042 disposed on the side of the bag hanging frame near the bag hanging slider. The bag hanging slider and the bag hanging slide rail slide in a sliding fit. The bag hanging switching cylinder can push the bag hanging mounting base plate and the two bag hanging rods to move along the bag hanging slide rail to realize the bag hanging compartment switching function.

[0025] In this embodiment of the utility model, a bag-hanging brush A107 is provided near the outer end of the bag-hanging rod; the bag-hanging brush plays a limiting role on the soft handle of the packaging bag, reducing the probability of taking the next bag out when taking out the bag.

[0026] In this embodiment of the utility model, the bag hanging rod A103 includes two spaced straight rods A1031, and an arc-shaped block A1032 is provided at the outer end of the two straight rods; a soft-handled bag is hung on the bag hanging rod, and the smooth arc-shaped block is installed at the end of the bag hanging rod to facilitate workers to hang the bag and the bag retrieval mechanism to retrieve the bag; the inner ends of the two straight rods are connected to the bag hanging mounting base plate; the bag hanging brush is installed in the gap between the two straight rods, and the upper surface of the bag hanging brush is higher than the upper surface of the straight rod.

[0027] In this embodiment of the utility model, the bag pushing mechanism A2 includes a bag pushing machine base A201, a lifting bag pushing module A202, and a bag pushing cylinder A203. The lifting bag pushing module and the bag pushing machine base are slidably engaged via a bag pushing sliding component A204. The bag pushing cylinder is used to drive the lifting bag pushing module to move along the length direction of the bag pushing mechanism.

[0028] In this embodiment of the utility model, the lifting and pushing bag module A202 includes a pushing bag cylinder fixing plate A2021, a guide shaft mounting seat A2022, a lifting guide shaft A2023, and a pushing bag plate A2024 arranged sequentially from top to bottom. The upper end of the lifting guide shaft is slidably engaged with a linear bearing A2025 disposed on the guide shaft mounting seat, and the lower end of the lifting guide shaft is connected to the pushing bag plate. Pushing bag lifting cylinders A2026 for driving the pushing bag plate to rise and fall are disposed on both sides of the guide shaft mounting seat.

[0029] The aforementioned pusher plate A2024 has an "E" shaped cross section, meaning that the lower part of the pusher plate is provided with an avoidance groove A2027 to avoid the two hanging bag rods, thereby allowing the protrusion at the lower part of the pusher plate to extend downward and contact the inner side of the hanging soft handle packaging bag.

[0030] In this embodiment of the utility model, one end of the push-bag cylinder is connected to the lower part of one side of the push-bag cylinder, and the telescopic end of the push-bag cylinder is connected to the push-bag cylinder fixing plate via the push-bag cylinder connecting seat A2028.

[0031] In this embodiment of the utility model, a bag-pushing lifting cylinder seat A2029 is provided on both sides of the guide shaft mounting seat, and the bag-pushing cylinder is fixed on the bag-pushing lifting seat.

[0032] In this embodiment of the utility model, the bag pushing sliding assembly A204 includes a bag pushing slider A2041 disposed on the bag pushing cylinder fixing plate and a bag pushing slide rail A2042 disposed below the bag pushing machine base, wherein the bag pushing slider and the bag pushing slide rail are slidably engaged.

[0033] In this embodiment of the invention, during operation: the outer soft handle of the soft-handled packaging bag is aligned with two hanging rods, one of which corresponds to the working position of the bag-pushing mechanism; after the worker completes the bag-hanging work, the bag-pushing cylinder of the bag-pushing mechanism extends to its longest position, driving the bag-pushing plate to descend, positioning the bag-pushing plate behind the last soft-handled packaging bag; then the bag-pushing cylinder retracts, pushing the soft-handled packaging bag hanging on the bag-pushing rod towards the hanging rod near the hanging brush, until the outer soft handle of the foremost soft-handled packaging bag is moved as close as possible to the hanging brush position at the outer end of the hanging rod, thereby... All soft-handled bags are positioned between the bag-hanging brush and the bag-pushing plate. As the first soft-handled bag is removed, the bag-pushing plate gradually moves closer to the bag-hanging brush, ensuring that a soft-handled bag is always in contact with the bag-hanging brush for easy bag removal. When all the soft-handled bags on a bag-hanging bar are used up, the bag-pushing mechanism resets, and the bag-hanging switching cylinder drives the bag-hanging mounting plate and bag-hanging bar to move away from the bag-pushing mechanism. Meanwhile, another bag-hanging bar full of soft-handled bags moves to the position of the bag-pushing mechanism, thus realizing the bag-hanging switching function of the bag-hanging bar.
