Description

Technical Field

[0001] This utility model relates to a side protective bag mechanism for a soft-handle 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. While existing fully automatic rice packaging equipment is relatively mature, it is not compatible with soft-handled bags when using them for packaging. To address the storage issue of soft-handled bags, when suspending stacks of bags on a hanging rod, the outermost bag must always be at the outermost position on the rod to ensure optimal bag retrieval. After the first outermost bag is removed, the second bag is pushed to the outermost position. During the movement of the bags along the length of the hanging rod, to prevent swaying and ensure consistent bag retrieval height and width, a limiting mechanism is needed. This leads to the development of this solution. Utility Model Content

[0003] This utility model improves upon the above-mentioned problems by providing a side protection bag mechanism for a soft-handle packaging bag. The mechanism is simple in structure and easy to use, effectively limiting the soft-handle packaging bag and ensuring that the height and width of the bag are basically consistent when taking it out.

[0004] This utility model is constructed as follows: it includes a protective bag mounting frame and two protective bag width adjusting plates disposed on the protective bag mounting frame. Each protective bag width adjusting plate is provided with a flip-up protective bag plate above it. The protective bag plate is rotatably engaged with the protective bag width adjusting plate via a protective bag rotating frame. A protective bag flipping cylinder is disposed below the protective bag width adjusting plate. The piston guide rod of the protective bag flipping cylinder is hinged to the protective bag rotating frame.

[0005] Furthermore, a bag width adjustment assembly is provided between the bag width adjustment plate and the bag mounting frame. The bag width adjustment assembly includes a bag screw and a bag slide rail respectively disposed on both sides of the bag mounting frame. A movable seat is provided below one side of the bag width adjustment plate, and the movable seat is threadedly engaged with the bag screw. A bag slider is provided below the other side of the bag width adjustment plate, and the bag slider is slidably engaged with the bag slide rail.

[0006] Furthermore, a seated bearing is provided above the protective bag mounting frame, the protective bag screw passes through the seated bearing and rotates with it, and a handwheel is provided at the outer end of the protective bag screw.

[0007] Furthermore, the protective screw is provided with threaded portions at both ends with opposite directions of rotation, and the internal threaded holes of the two movable seats respectively cooperate with the corresponding threaded portions. When the protective screw rotates, the two movable seats move closer or further apart synchronously.

[0008] Furthermore, a top bag plate is provided between the output ends of the two protective bag plates, and a top bag mounting frame is provided on the protective bag mounting frame. The top bag mounting frame is equipped with a top bag cylinder for driving the top bag plate to rise and fall.

[0009] Furthermore, a protective bag mounting frame is provided below the protective bag mounting frame, and a protective bag switching cylinder is installed on the protective bag mounting frame to drive the protective bag mounting frame to lift and lower as a whole.

[0010] Furthermore, the protective bag rotating frame includes a protective bag rotating frame shaft and multiple arc-shaped rotating frame arms disposed on the protective bag rotating frame shaft. The arc-shaped rotating frame arms are fixedly connected to the outer side of the protective bag plate. The protective bag rotating frame shaft is rotatably engaged with two second joint bearings disposed on the protective bag width adjustment plate. A rotating frame connecting rod is provided in the middle of the protective bag rotating frame shaft, and the rotating frame connecting rod is hinged to the piston guide rod of the protective bag flipping cylinder.

[0011] Furthermore, two first joint bearings are provided below the protective bag width adjustment plate, and the protective bag flipping cylinder is rotated and engaged with the first joint bearings via a first rotating shaft.

[0012] 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. When the handles of multiple soft-handled bags are suspended on the bag-hanging rod, the multiple soft-handled bags need to be pushed towards the bag-picking station along the length of the bag-hanging rod. The two vertically erected bag-protecting plates and top bag plate limit the movement of these soft-handled bags, thereby ensuring that the height and width of each soft-handled bag are basically the same when it is picked up. When the bag-protecting plates need to be erected, the two bag-protecting flipping cylinders drive the bag-protecting plates to flip upwards and stand upright via the bag-protecting rotating frame. When the bag-protecting plates need to be flattened, the two bag-protecting flipping cylinders drive the bag-protecting rotating frame to flip downwards and flatten the bags. To accommodate soft-handle packaging bags of different sizes, the working relationship between the two protective bag plates can be adjusted using a protective bag width adjustment component. When the protective bag width adjustment component is in operation, the protective bag screw is rotated by a handwheel, which in turn moves the two protective bag width adjustment plates closer together or further apart via the protective bag slider and the moving seat, thus adapting to the different widths of soft-handle packaging bags for protection. At the same time, to accommodate the different sizes of soft-handle packaging bags, a top bag cylinder drives the top bag plate to move up and down, allowing the top bag plate to adapt to different soft-handle packaging bags. A protective bag switching cylinder drives the protective bag mounting frame to move up or down as a whole, adapting to the height of the soft-handle packaging bags. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Example: Figures 1-5 As shown, a side protective bag mechanism for a soft-handle packaging bag is provided. The side protective bag mechanism C includes a protective bag mounting frame C1 and two protective bag width adjusting plates C2 disposed on the protective bag mounting frame. Each protective bag width adjusting plate is provided with a flip-up protective bag plate C3 above it. The protective bag plate is rotatably engaged with the protective bag width adjusting plate C2 via a protective bag rotating frame C4. A protective bag flipping cylinder C5 is disposed below the protective bag width adjusting plate. The piston guide rod of the protective bag flipping cylinder is hinged to the protective bag rotating frame.

[0020] The protective bag panels are symmetrically designed, allowing them to be flipped over simultaneously or on one side only.

[0021] When the side bag protection mechanism is working: When the handles of multiple soft-handled packaging bags A3 are suspended on the bag hanging rod, the multiple soft-handled packaging bags need to be pushed towards the bag picking station along the length of the bag hanging rod. The two vertically erected bag protection plates and top bag plates play a limiting role for these soft-handled packaging bags, thereby ensuring that the height and width of each soft-handled packaging bag are basically the same when picking up the bag. When the bag protection plates need to be erected, the two bag protection flipping cylinders drive the bag protection plates to flip upward and erect through the bag protection rotating frame. When the bag protection plates need to be flattened, the two bag protection flipping cylinders drive the bag protection plates to flip downward and flatten through the bag protection rotating frame.

[0022] To accommodate soft-handle packaging bags of different sizes, the spacing between the two protective bag plates can be adjusted using a protective bag width adjustment component. When the protective bag width adjustment component is in operation, the protective bag screw is rotated via a handwheel, which in turn moves the two protective bag width adjustment plates closer together or further apart via the protective bag slider and the moving seat, thus adapting to the different widths of soft-handle packaging bags for protection. At the same time, to accommodate the different sizes of soft-handle packaging bags, a top bag cylinder drives the top bag plate to move up and down, allowing the top bag plate to adapt to different soft-handle packaging bags. A protective bag switching cylinder drives the protective bag mounting frame to move up or down as a whole, adapting to the height of the soft-handle packaging bags.
