Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment and relates to a bidirectional winding packaging machine. Background Art

[0002] For strip-shaped pieces in segments or continuously pulled out, they are wrapped and packaged, such as multi-strand twisted ropes, plastic extruded strips, etc., and their outer surfaces are wrapped with tapes so that they can be effectively separated and protected from each other when stacked and stored. In order to improve the wrapping efficiency and protection effect, the material used for wrapping is generally a protective film of a certain width, which is densely wrapped in the same direction on the outer surface of the piece to be wrapped.

[0003] The existing wrapping packaging machine generally includes a fixed ring with a notch, a gear ring (with a notch) rotatably connected to the fixed ring and a discharge wheel arranged on the gear ring. The gear ring is driven to rotate so that the protective film pulled out by the discharge wheel can be wrapped around the rod-shaped member passing through the center position of the gear ring at a uniform speed. This packaging method is particularly prone to belt breakage, that is, the winding material is disconnected. If a thicker film is used, the replacement cycle of the discharge wheel will be too short. In addition, during the stacking and storage process of the strips, most of them only need to prevent contact and friction with each other, and do not require dense wrapping, thus resulting in waste of winding materials. Summary of the invention

[0004] The purpose of the present invention is to provide a bidirectional wrapping baling machine in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to improve the wrapping quality.

[0005] The object of the present invention can be achieved through the following technical solutions: A bidirectional winding strapping machine, characterized in that it includes a first gear ring, a first mounting ring, a second mounting ring and a second gear ring, each of which has a notch, and the outer side of the first mounting ring has a plurality of limiting guide wheels 1, and the first gear ring is rotatably connected between each limiting guide wheel 1; the outer side of the second mounting ring has a plurality of limiting guide wheels 2, and the second gear ring is rotatably connected between each limiting guide wheel 2, the first mounting ring is fixedly connected to the second mounting ring, and there is a spacing between the first mounting ring and the second mounting ring; the strapping machine also includes a driving bevel gear and a driven bevel gear, the driving bevel gear and the driven bevel gear are parallel to each other, the driving bevel gear and the driven bevel gear are both inserted between the first mounting ring and the second mounting ring, the first gear ring and the second gear ring are synchronously meshed with the driving bevel gear, and the first gear ring and the second gear ring are synchronously meshed with the driven bevel gear; a pay-off wheel 1 is rotatably connected to the outer side of the first gear ring, and a pay-off wheel 2 is rotatably connected to the outer side of the second gear ring.

[0006] Furthermore, the first mounting ring and the second mounting ring are fixedly connected via a plurality of connecting columns.

[0007] The difference between this solution and the existing wrapping packaging machine lies not only in the different wrapping methods, but also in the use of ropes instead of traditional films, so that it is not easy to wrinkle, tear or break. In addition, while ensuring that the outer diameter of the rope is sufficient to meet the strength requirements, the storage capacity of the rope is large, and the cycle for replacing the pay-off wheel one and the pay-off wheel two is longer, or in other words, longer items to be packaged can be wrapped.

[0008] This solution adopts a bidirectional winding method to form a simple woven structure on the surface of the strip to be packaged. It can not only form a separation on the surface of the packaged piece that will not rub against each other after stacking or rolling, but also form a certain gap. Compared with the traditional full-area wrapping packaging, it has obvious advantages for some materials that require heat dissipation or ventilation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figures 1 to 5As shown, the bidirectional winding strapping machine includes a first gear ring 1, a first mounting ring 3, a second mounting ring 4 and a second gear ring 2. The first gear ring 1, the second gear ring 2, the first mounting ring 3 and the second mounting ring 4 all have a notch. The outer side surface of the first mounting ring 3 has a plurality of limiting guide wheels 5. The first gear ring 1 is rotatably connected between each limiting guide wheel 5; the outer side surface of the second mounting ring 4 has a plurality of limiting guide wheels 6. The second gear ring 2 is rotatably connected between each limiting guide wheel 6. The first mounting ring 3 is fixedly connected to the second mounting ring 4. There is a gap between the mounting ring 3 and the second mounting ring 4; the strapping machine also includes a driving bevel gear 7 and a driven bevel gear 8, the driving bevel gear 7 and the driven bevel gear 8 are parallel to each other, the driving bevel gear 7 and the driven bevel gear 8 are both inserted between the first mounting ring 3 and the second mounting ring 4, the first gear ring 1 and the second gear ring 2 are synchronously meshed with the driving bevel gear 7, and the first gear ring 1 and the second gear ring 2 are synchronously meshed with the driven bevel gear 8; the outer surface of the first gear ring 1 is rotatably connected to the wire pay-off wheel 1 9, and the outer surface of the second gear ring 2 is rotatably connected to the wire pay-off wheel 2 10. The first mounting ring 3 and the second mounting ring 4 are fixedly connected by a plurality of connecting columns 11.

[0017] The difference between this solution and the existing wrapping packaging machine is not only the different wrapping method, but also the use of ropes instead of traditional films, so that it is not easy to wrinkle, tear and break. In addition, while ensuring that the outer diameter of the wire is sufficient to meet its strength requirements, the storage capacity of the wire is large, and the cycle of replacing the pay-off wheel 1 9 and the pay-off wheel 2 10 is longer, or in other words, longer items to be packaged can be wrapped.

[0018] This solution adopts a bidirectional winding method to form a simple woven structure on the surface of the strip to be packaged. It can not only form a separation on the surface of the packaged piece that will not rub against each other after stacking or rolling, but also form a certain gap. Compared with the traditional full-area wrapping packaging, it has obvious advantages for some materials that require heat dissipation or ventilation.

[0019] Specifically, the driving bevel gear 7 is connected to a motor and click-fixed on the frame, the first mounting ring 3 and the second mounting ring 4 are fixed on the frame, and the driven bevel gear 8 is rotatably connected to the frame. The frame referred to here is the floor-standing connecting frame of the baling machine, and the center position formed by the wire or rod-shaped object to be wrapped passes through each ring. The notch of the first mounting ring 3 and the notch of the second mounting ring 4 always overlap, and the notch of the first gear ring 1 and the second gear ring 2 can also overlap with the notch of the first mounting ring 3 after rotation, which is used for putting in or taking out the object to be wrapped. In the case where the driving bevel gear 7 is provided, the driven bevel gear 8 is also provided to ensure that the driven bevel gear 8 can simultaneously mesh with the first gear ring 1 and the second gear ring 2 when the driving bevel gear 7 passes through the notch position of the first gear ring 1 or the second gear ring 2, so that when one of the first gear ring 1 and the second gear ring 2 is driven, the two can maintain synchronization and rotate in opposite directions.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
