Description

Technical Field

[0001] This utility model relates to the field of heavy powder packaging technology, specifically a heavy powder soft bag vertical secondary bagging packaging machine. Background Technology

[0002] For the secondary packaging of powder, the existing secondary bagging machines on the market are mainly designed for repackaging multiple small packets of powder. This technology is quite common in the market. It simply involves arranging multiple small packets in an orderly manner, stacking them, and then packing them into a secondary packaging bag. This secondary packaging process is relatively simple. The difficulty lies in how to arrange and stack multiple small packets in an orderly manner. Once the orderly arrangement and stacking is solved, the packets can be neatly packed into the secondary packaging bag. These multiple small packaging bags are lighter than large bags, and there is no problem with controlling the shape of the small packets or the impact of the soft bags falling on the woven bags.

[0003] When packaging powder in soft bags for secondary packaging, the soft bags are placed into woven bags. If the soft bags are heavy, they are more likely to deform due to gravity. Currently, most secondary bagging methods use vertical bagging. Without external force to restrain them during the bagging process, the soft bags are prone to deformation and changes in their external dimensions. This may result in the soft bags being unable to fit into the woven bags, affecting the production schedule. Utility Model Content

[0004] To address the aforementioned issues, this application provides a heavy-duty powder soft bag vertical secondary bagging and packaging machine, which solves the problem that heavy-duty soft bags may deform before entering the woven bag and thus fail to enter the woven bag.

[0005] A heavy-duty powder soft bag vertical secondary bagging packaging machine includes a bag picking, pre-opening and bag preparation robot arm mechanism for automatically feeding woven bags. A bag clamping mechanism for opening the woven bag opening to adapt to the soft bag is installed on the outside of the bag picking, pre-opening and bag preparation robot arm mechanism. A shaping chamber for shaping the soft bag is installed on the outside of the bag clamping mechanism. The shaping chamber includes two slidingly inserted concave plates with outward expansion at the top. Two bidirectional screws for adjusting the distance between the two concave plates are installed on the outside of the two concave plates.

[0006] A support plate is hinged to the bottom of the concave plate, and a cylinder that drives its rotation is hinged to the outside of the support plate.

[0007] In addition, the shaping chamber also includes a mounting frame, a bidirectional lead screw is rotatably mounted inside the mounting frame, and a sprocket is fixedly mounted on the outside of the bidirectional lead screw, with the sprockets connected by a chain.

[0008] In addition, a handwheel is fixedly installed at the end of the bidirectional lead screw described in one of them.

[0009] In addition, a sliding plate is coupled to the outer side of the bidirectional lead screw, and the sliding plate is fixedly connected to the concave plate.

[0010] In addition, the top of the cylinder is hinged to the outside of the concave plate.

[0011] In addition, a lower main frame is installed on the outside of the bag-picking, pre-opening, and bag-preparing robotic arm mechanism, and a mounting frame is fixedly installed on the inside of the lower main frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] The present invention describes a heavy-duty powder soft bag vertical secondary bagging packaging machine. During the secondary bagging, the support plate expands outward to open the bag opening of the woven bag, limiting the shape and size of the bag opening, making it easier for the soft bag to enter the woven bag, and reducing the possibility of movement obstruction between the two.

[0014] Before the soft package slides into the woven bag, it passes through a concave plate. The staff adjusts the overall inner dimensions of the two concave plates according to the packaging size of the soft package. After passing through the concave plate, the soft package is squeezed and shaped to fit the size of the woven bag, further reducing the possibility of movement obstruction between the soft package and the woven bag. The adjustable concave plate can accommodate soft packages of various sizes, enhancing its practicality. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] like Figures 1-3 As shown, this utility model embodiment provides a heavy-duty powder soft bag vertical secondary bagging packaging machine, including a bag picking, pre-opening and bag preparation robot mechanism 1 for automatically feeding woven bags. A bag clamping mechanism 2 for opening the woven bag opening to adapt to the soft bag is installed on the outside of the bag picking, pre-opening and bag preparation robot mechanism 1. A shaping chamber 4 for shaping the soft bag is installed on the outside of the bag clamping mechanism 2. The shaping chamber 4 includes two slidingly inserted concave plates 42. The top of the concave plates 42 is expanded outward to facilitate the entry of the soft bag. Two bidirectional screws 44 are installed on the outside of the two concave plates 42 to drive the adjustment of their spacing, which limits the size of the soft bag after shaping. It can also adapt to more soft bags for secondary bagging, enhancing practicality.

[0025] Furthermore, the shaping chamber 4 also includes a mounting frame 41, with a bidirectional lead screw 44 rotatably mounted inside the mounting frame 41, and a sprocket fixedly mounted on the outside of the bidirectional lead screw 44. The sprockets are connected by a chain, and the sprockets and chain enable the two bidirectional lead screws 44 to rotate synchronously.

[0026] Furthermore, a handwheel 43 is fixedly installed at the end of the bidirectional lead screw 44, which makes it convenient for the operator to rotate the bidirectional lead screw 44 to adjust the overall inner size of the two concave plates 42. Alternatively, the handwheel 43 can be replaced with a motor as needed to achieve automatic adjustment.

[0027] In this embodiment, the worker rotates the handwheel 43 according to the production batch, i.e. the packaging size of the soft bag, so that the bidirectional lead screw 44 adjusts the overall inner size of the two concave plates 42. The soft bag passing through the concave plates 42 is squeezed and shaped to match the size of the woven bag, further reducing the possibility of movement obstruction between the soft bag and the woven bag. Moreover, the adjustable concave plates 42 can be adapted to soft bags of various sizes, enhancing practicality.

[0028] Furthermore, a support plate 47 is hinged to the bottom of the concave plate 42 to open the bag opening from the inside of the woven bag, reducing the possibility of movement obstruction between the soft bag and the woven bag opening. A cylinder 46 that drives the support plate 47 to rotate is hinged to the outside of the support plate 47, and the top of the cylinder 46 is hinged to the outside of the concave plate 42.

[0029] In this embodiment, the bag-picking, pre-opening, and bag-preparing robotic arm mechanism 1 and the bag-clamping mechanism 2 work together to open and move the woven bag to the periphery of the support plate 47. The telescopic end of the cylinder 46 shortens, causing the support plate 47 to expand outward, opening the bag opening of the woven bag, further defining the shape and size of the bag opening, making it easier for soft bags to enter the woven bag, and reducing the possibility of movement obstruction between the two.

[0030] Furthermore, a sliding plate 45 is coupled and installed on the outer side of the bidirectional lead screw 44, and the sliding plate 45 is fixedly connected to the concave plate 42.

[0031] Furthermore, a lower main frame 5 is installed on the outside of the bag-picking, pre-opening, and bag-preparing robotic arm mechanism 1, and a mounting bracket 41 is fixedly installed on the inside of the lower main frame 5.

[0032] Furthermore, a double-layer inclined conveyor 12 for automatic feeding is installed inside the lower main frame 5. A pressing and shaping conveyor 11 for secondary smoothing of soft packages is connected to the outside of the discharge port of the double-layer inclined conveyor 12. A feeding hopper 10 is connected to the outside of the discharge port of the pressing and shaping conveyor 11. The discharge end of the feeding hopper 10 is engaged with the top of the concave plate 42.

[0033] Furthermore, the concave plate 42 is equipped with a bag-feeding lifting mechanism 6 that helps the soft bag to smoothly enter the woven bag. A bag-holding mechanism 3 is installed on the outside of the bag-feeding lifting mechanism 6 to transport the woven bag that has been bagged twice to the next work station.

[0034] Furthermore, the end of the bag-holding mechanism 3 is connected to a lifting sewing conveyor 9 for sewing the bag opening, and the top of the lifting sewing conveyor 9 is equipped with a straight edge mechanism 8 for aligning the bag opening and facilitating sewing.

[0035] In this embodiment, as the soft bag falls into the bottom of the bag, the bag-holding mechanism 3 moves from its original position to the bag-dropping position, clamping and moving the woven bag containing the soft bag onto the lifting sewing conveyor 9 for sewing.

[0036] Furthermore, the top of the lifting sewing conveyor 9 is equipped with a bag opening guide mechanism 7 that limits the movement trajectory of the woven bag.

[0037] Furthermore, the bag-picking and pre-opening bag-preparing robotic arm mechanism 1, bag-clamping mechanism 2, bag-holding mechanism 3, lower main frame 5, bag-entry and bag-supporting lifting mechanism 6, bag-mouth guiding mechanism 7, straight edge mechanism 8, lifting and sewing conveyor 9, unloading bin 10, pressing and shaping conveyor 11, and double-layer inclined conveyor 12 can all draw on existing technologies. There are many mature solutions in the existing technology that can work in conjunction with the shaping bin 4 in this application. This is not an innovation of this application, and those skilled in the art will clearly know it. This application will not elaborate on it. The bag-clamping mechanism 2, bag-holding mechanism 3, and bag-entry and bag-supporting lifting mechanism 6 are installed on the lower main frame 5.

[0038] Specific working methods:

[0039] During feeding, the soft bag is conveyed to the pressing and shaping conveyor 11 via the double-layer inclined conveyor 12, and then the soft bag is conveyed to the unloading hopper 10. After passing through the unloading hopper 10, the soft bag enters the shaping hopper 4. The top of the concave plate 42 expands outward to facilitate the entry of the soft bag. Before this, the bag picking, pre-opening and bag preparation robot arm 1 and the bag clamping mechanism 2 work together to open the woven bag and move it to the periphery of the support plate 47. The telescopic end of the cylinder 46 shortens, driving the support plate 47 to expand outward, opening the bag mouth of the woven bag, further limiting the shape and size of the bag mouth of the woven bag, making it easier for the soft bag to enter the woven bag, and reducing the possibility of movement obstruction between the two.

[0040] According to the production batch, i.e. the packaging size of the soft pack, the staff turns the handwheel 43, so that the bidirectional screw 44 adjusts the overall inner size of the two concave plates 42. The soft pack is squeezed and shaped by the concave plates 42 to match the size of the woven bag, which further reduces the possibility of movement obstruction between the soft pack and the woven bag. Moreover, the adjustable concave plates 42 can be adapted to soft packs of various sizes, which enhances practicality.

[0041] When the soft bag enters the woven bag from the shaping chamber 4, the bag-feeding lifting mechanism 6 assists in bagging. At the same time as the soft bag falls to the bottom of the bag, the bag-holding mechanism 3 moves from its original position to the bag-dropping position, clamping and moving the woven bag containing the soft bag onto the lifting sewing conveyor 9 for sewing.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
