Technical Field

[0001] The utility model relates to the technical field of ton bag unfolding devices, and more specifically, to a ton bag opening fixing structure for a polypropylene film ton bag packaging machine. Background Art

[0002] A ton bag is a medium-sized bulk container, usually made of high-strength polypropylene, polyethylene and other materials. It has the characteristics of large capacity, strong load-bearing capacity, and easy loading and unloading. It has been widely used in logistics, chemical, building materials, grain and other industries. Ton bags can load a large amount of goods at one time, improving transportation efficiency. At the same time, ton bags can be reused, reducing packaging costs and playing a positive role in environmental protection.

[0003] When operators pack materials in ton bags, they often use ton bag packaging machines to quickly pack the materials. Although the existing ton bag packaging machines have basic packaging functions in actual use, during the ton bag packaging process, it is necessary to ensure that the bag opening is always in an open state to facilitate the entry of materials into the ton bag. Therefore, it is necessary to design a ton bag opening fixing structure to fix the bag opening in an open state. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a ton bag opening fixing structure for a polypropylene film ton bag packaging machine, which has the advantage of keeping the bag opening fixed.

[0005] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip.

[0006] As an optimal technical solution of the present invention, the inner surface of the lower side of the mounting block is fixedly mounted with the No. 2 motor, the other end of the output shaft of the No. 2 motor is fixedly sleeved with a rotating shaft, and the outer surface of the rotating shaft is fixedly sleeved with the No. 2 gear located on the outside of the mounting block.

[0007] As a preferred technical solution of the present invention, the outer surface of the No. 2 gear is meshedly connected with the No. 3 gear, and the inner surface of the No. 3 gear is fixedly sleeved with the outer surface of the bag pulling rod.

[0008] As a preferred technical solution of the present invention, the lower surface of the gear ring is fixedly connected to a limiting ring, and the inner surface of the limiting ring is movably connected to the outer surface of the circular plate.

[0009] As an optimal technical solution of the present invention, the upper surface of the circular plate is movably connected to the limiting column, the bottom end of the limiting column passes through the circular plate and extends to the bottom of the circular plate and is fixedly connected to the bottom plate, the lower surface of the circular plate is fixedly connected to the connecting block, and the inner surface of the connecting block and the outer surface of the limiting column are movably socketed.

[0010] As an optimal technical solution of the present invention, a No. 3 motor is fixedly installed on the right side of the upper surface of the base plate, the other end of the output shaft of the No. 3 motor is fixedly sleeved with a rotating shaft, and the outer surface of the rotating shaft is fixedly sleeved with a No. 1 connecting rod.

[0011] As a preferred technical solution of the present invention, the other end of the No. 1 connecting rod is hinged to the No. 2 connecting rod, and the other end of the No. 2 connecting rod is hinged to the right surface of the connecting block.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model is provided with a moving block, a ring gear, a center column, a driving rod and a bag pulling rod. When the No. 1 motor is running, the circular shaft and the No. 1 gear will start to rotate. Since the ring gear and the No. 1 gear are engaged with each other, the ring gear and the cylinder will start to rotate driven by the No. 1 gear, and the rotation of the cylinder will drive the driving rod, so that the driving rod starts to rotate with the center column as the axis. At the same time, the inner surface of the driving rod will drive the moving block, so that the four moving blocks and the mounting block as a whole start to move away from each other along the inner surface of the circular plate. At this time, the four handles of the ton bag will be pulled open by the four bag pulling rods, thereby ensuring that the bag mouth of the ton bag is always fixed in an open state.

[0014] 2. The utility model sets a circular plate, a limiting column, a connecting block, a No. 1 connecting rod and a No. 2 connecting rod. When the No. 3 motor is running, the rotating shaft and the No. 1 connecting rod will start to rotate. The rotation of the No. 1 connecting rod will drive the No. 2 connecting rod, so that the No. 2 connecting rod starts to rotate with the other end of the No. 1 connecting rod as the axis. At the same time, the other end of the No. 2 connecting rod will drive the entire circular plate in this process, so that the entire circular plate starts to move up and down under the limit of the limiting column. As a result, the entire circular plate can be suitable for ton bags of different heights, thereby effectively improving the scope of application of the entire circular plate.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a ton bag mouth fixing structure for a polypropylene film ton bag packaging machine, comprising a circular plate 1, the upper surface of the circular plate 1 is movably connected with a moving block 2, the bottom end of the moving block 2 passes through the circular plate 1 and extends to the bottom of the circular plate 1 and is fixedly connected with a mounting block 10, the inner surface of the upper side of the mounting block 10 is movably sleeved with a bag pulling rod 11, the upper surface of the circular plate 1 is movably connected with a gear ring 3 located on the outside of the moving block 2, the upper surface of the gear ring 3 is fixedly connected with a cylinder 4, the upper surface of the circular plate 1 is fixedly connected with a center column 5, the outer surface of the center column 5 is hinged with a driving rod 6, the inner surface of the outer side of the driving rod 6 and the outer surface of the cylinder 4 are movably connected, the inner surface of the inner side of the driving rod 6 and the outer surface of the moving block 2 are movably connected, a No. 1 motor 7 is fixedly installed on the rear side of the lower surface of the circular plate 1, the other end of the output shaft of the No. 1 motor 7 is fixedly sleeved with a circular shaft 8, the outer surface of the circular shaft 8 is fixedly sleeved with a No. 1 gear 9, and the outer surface of the No. 1 gear 9 is meshed with the outer surface of the gear ring 3.

[0023] The operation of motor No. 1 7 will cause the circular shaft 8 and gear No. 1 9 to start rotating. At this time, the ring gear 3 and the cylinder 4 will start rotating driven by gear No. 1 9, and the rotation of the cylinder 4 will drive the driving rod 6, causing the driving rod 6 to rotate with the center column 5 as the axis. In this process, the moving block 2 and the mounting block 10 as a whole will start moving toward and away from each other along the inner surface of the circular plate 1 driven by the driving rod 6.

[0024] The second motor 12 is fixedly mounted on the inner surface of the lower side of the mounting block 10 , the other end of the output shaft of the second motor 12 is fixedly sleeved with a rotating shaft 13 , and the outer surface of the rotating shaft 13 is fixedly sleeved with a second gear 14 located outside the mounting block 10 .

[0025] When the second motor 12 is running, the rotating shaft 13 and the second gear 14 start to rotate.

[0026] The outer surface of the second gear 14 is meshedly connected with the third gear 15 , and the inner surface of the third gear 15 is fixedly sleeved with the outer surface of the bag pulling rod 11 .

[0027] The rotation of the second gear 14 drives the third gear 15 , causing the third gear 15 and the bag pulling rod 11 to start rotating.

[0028] The lower surface of the gear ring 3 is fixedly connected to the limiting ring 16 , and the inner surface of the limiting ring 16 is movably connected to the outer surface of the circular plate 1 .

[0029] The design of the limiting ring 16 serves to limit the entire gear ring 3 during its rotation.

[0030] Among them, the upper surface of the circular plate 1 is movably connected to the limiting column 17, the bottom end of the limiting column 17 passes through the circular plate 1 and extends to the bottom of the circular plate 1 and is fixedly connected to the bottom plate 18, and the lower surface of the circular plate 1 is fixedly connected to the connecting block 19, and the inner surface of the connecting block 19 and the outer surface of the limiting column 17 are movably connected.

[0031] The circular plate 1 as a whole and the connecting block 19 can move up and down under the limitation of the outer surface of the limiting column 17.

[0032] Among them, a No. 3 motor 20 is fixedly installed on the right side of the upper surface of the base plate 18, and a rotating shaft 21 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 20, and a No. 1 connecting rod 22 is fixedly sleeved on the outer surface of the rotating shaft 21.

[0033] When the third motor 20 is running, the rotating shaft 21 and the first connecting rod 22 will start to rotate.

[0034] The other end of the No. 1 connecting rod 22 is hinged to the No. 2 connecting rod 23 , and the other end of the No. 2 connecting rod 23 is hinged to the right surface of the connecting block 19 .

[0035] The rotation of the No. 1 connecting rod 22 drives the No. 2 connecting rod 23 , so that the No. 2 connecting rod 23 starts to drive the entire circular plate 1 during the rotation process, and finally the entire circular plate 1 moves up and down.

[0036] The working principle and use process of this utility model:

[0037] First, the operator places the ton bag in the center of the upper surface of the base plate 18 and makes the four handles of the ton bag face the positions of the four bag pulling rods 11 respectively. Then the operator starts the No. 3 motor 20. As the No. 3 motor 20 runs, the rotating shaft 21 and the No. 1 connecting rod 22 will start to rotate, and the rotation of the No. 1 connecting rod 22 will drive the No. 2 connecting rod 23 so that the No. 2 connecting rod 23 also starts to rotate. At the same time, the other end of the No. 2 connecting rod 23 will drive the connecting block 19 and the circular plate 1, so that the circular plate 1 as a whole starts to move upward along the outer surface of the limit column 17 until the four bag pulling rods 11 are aligned with the four handles of the ton bag.

[0038] Then the operator starts motor No. 1 7. As motor No. 1 runs, the circular shaft 8 and gear No. 1 9 begin to rotate, and the rotation of gear No. 1 9 drives the ring gear 3, causing the ring gear 3 and cylinder 4 to begin to rotate under the limit of the limit ring 16. During this process, the rotation of the cylinder 4 causes the driving rod 6 to begin to rotate with the center column 5 as the axis, and the rotation of the driving rod 6 drives the moving block 2, causing the four moving blocks 2 and the mounting block 10 as a whole to begin to move toward each other along the inner surface of the circular plate 1, and finally the four bag pulling rods 11 will be inserted into the gaps of the four handles.

[0039] At this time, the operator starts the No. 2 motor 12. As the No. 2 motor 12 runs, the rotating shaft 13 and the No. 2 gear 14 will start to rotate, and the rotation of the No. 2 gear 14 will drive the No. 3 gear 15, so that the No. 3 gear 15 and the bag pulling rod 11 start to rotate. When the bag pulling rod 11 rotates one hundred and eighty degrees, the four bag pulling rods 11 can hook the four handles respectively. At this time, the operator starts the No. 1 motor 7 again, so that the four moving blocks 2 and the mounting block 10 start to move in opposite directions as a whole. Finally, the four bag pulling rods 11 will pull the four handles outward, which makes the bag mouth of the ton bag always in an open state, thereby facilitating the material ton bag packaging operation.
