Description

Technical Field

[0001] The invention belongs to the technical field of packaging and relates to a ton bag packaging machine and its application in ammonium perchlorate production. Background Art

[0002] The ton bag packaging machine is an automated equipment designed for large-capacity packaging. It is mainly used to package bulk materials such as crystalline particles and powdered particles with a weight ranging from hundreds of kilograms to several tons.

[0003] Existing ton bag packaging machines typically suspend ton bags via slings. As the filling process progresses, the material content of the ton bag gradually increases, increasing the risk of sling breakage. A broken sling can cause the ton bag to lose balance, tilting or partially falling. This poses a risk of injury and can also cause material leakage, disrupting the smooth filling process and ultimately impacting packaging efficiency and quality.

[0004] Ton bag packaging machines are widely used in the production of ammonium perchlorate.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 1-11 As shown, the present invention employs the following technical solution: a ton bag packaging machine includes a conveyor 1, a mounting plate 3, a movable plate 5, and a support assembly. The conveyor 1 is used to transport ton bags 25. Support rods 2 are fixed to both sides of the conveyor 1, and the mounting plate 3 is fixedly connected to the upper ends of the support rods 2. The mounting plate 3 is positioned above the conveyor 1.

[0023] The movable plate 5 is arranged below the mounting plate 3 and moves up and down. Figure 1 As shown, a plurality of hydraulic rods 4 are fixedly mounted on the top of the mounting plate 3. The telescopic ends of the hydraulic rods 4 vertically penetrate the mounting plate 3 downward and are fixedly connected to the movable plate 5. The arrangement of the plurality of hydraulic rods 4 is conducive to providing stable support for the movable plate 5.

[0024] During the filling process, the ton bag 25 is hung on the movable plate 5, and the movable plate 5 is driven by the hydraulic rod 4 to move back and forth, thereby causing the ton bag 25 to move back and forth, which is beneficial to improving the uniformity of the material filling in the ton bag 25.

[0025] The moving plate 5 is provided with a filling assembly, through which the material is filled into the conveying member 1. Figure 1 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 As shown, the filling assembly includes a feed pipe 17, a telescopic tube 18, and a funnel 19. One end of the feed pipe 17 is fixed to the upper end surface of the mounting plate 3. One end of the telescopic tube 18 is fixedly connected to the mounting plate 3 and communicates with the feed pipe 17. The other end of the telescopic tube 18 is fixedly connected to the movable plate 5 and communicates with the funnel 19. The upper end of the funnel 19 is fixedly mounted to the movable plate 5. A raised ring 20 is fixedly mounted to the lower end of the funnel 19. A fixing member is mounted on the movable plate 5 to secure the bulk bag 25 to the funnel 19.

[0026] In this embodiment, the fixing components include an electric telescopic rod 22 and a snap ring 23. Two fixed plates 21 are fixedly mounted to the lower end of the movable plate 5. Each fixed plate 21 is mounted with an electric telescopic rod 22, which is arranged horizontally. A snap ring 23 is connected to the telescopic end of each electric telescopic rod 22. The snap ring 23 is arc-shaped and fits the funnel 19. A rubber ring 24 is attached to the side of the snap ring 23 closest to the funnel 19.

[0027] In this embodiment, the cross section of the ton bag 25 is square, and the connection between adjacent sides of the ton bag 25 is provided with an edge seal 26. The four corners of the upper end surface of the ton bag 25 are provided with a sling 27. A filling pipe 28 is installed on the upper end surface of the ton bag 25.

[0028] During use, the ton bag 25 is suspended below the movable plate 5 via the support assembly. The funnel 19 is connected to the ton bag 25. Specifically, the filling tube 28 is placed over the raised ring 20, with the upper end of the filling tube 28 extending above the raised ring 20. The electric telescopic rod 22 is then activated, driving the clamping ring 23 toward the funnel 19. The two clamping rings 23 are then clamped onto the funnel 19 above the raised ring 20. The clamping rings 23 squeeze the funnel 19 through the rubber ring 24, thereby tightly fitting the upper end of the filling tube 28 to the funnel 19, preventing material from escaping through the upper end of the filling tube 28 during the filling process.

[0029] Four extension plates 29 are fixedly provided at the lower end of the movable plate 5 , and a support assembly is installed on each extension plate 29 . The four support assemblies correspond one to one with four slings 27 . The slings 27 are installed on the corresponding support assemblies, so that the ton bag 25 is hung below the movable plate 5 .

[0030] Each support assembly includes a first clamping member and two second clamping members. Figure 4 As shown, there are two second clamping members, and one of the second clamping members is arranged on one side below the first clamping member, and the other second clamping member is arranged on the other side below the first clamping member.

[0031] like Figure 6 、 Figure 7 As shown, the first clamping member includes two parallel first clamping plates 15. The first clamping plates 15 are rotatably mounted on an extension plate 29. Specifically, a first rotating shaft 6 is fixedly connected to the middle portion of one of the first clamping plates 15, and a second rotating shaft 7 is fixedly connected to the other first clamping plate 15. The second rotating shaft 7 is disposed below the first rotating shaft 6. Both the first rotating shaft 6 and the second rotating shaft 7 are rotatably connected to the extension plate 29. In a normal state, the first clamping plates 15 are horizontal, with a gap between the two first clamping plates 15.

[0032] Each second clamping member includes two parallel second clamping plates 16. The second clamping plates 16 are rotatably mounted on an extension plate 29. Specifically, one second clamping plate 16 is fixedly connected to a third rotating shaft 8, while the other second clamping plate 16 is fixedly connected to a fourth rotating shaft 9. Both the third rotating shaft 8 and the fourth rotating shaft 9 are rotatably mounted on the extension plate 29. Both the third rotating shaft 8 and the fourth rotating shaft 9 are disposed above the second clamping plates 16. Normally, the second clamping plates 16 are in a vertical position, with a gap between them.

[0033] When in use, the extension plate 29 is passed between the two first clamping plates 15 and the two second clamping plates 16 in the same second clamping member. The first clamping plate 15 below supports the sling 27.

[0034] In this embodiment, in order to facilitate the installation of the sling 27 on the support assembly, the first clamping plate 15 and the second clamping plate 16 are both arranged on a side of the extension plate 29 away from the funnel 19 .

[0035] A first transmission member is provided between the two first clamping plates 15 and between the two second clamping plates 16 in the same second clamping member. The first transmission member between the two first clamping plates 15 causes the two first clamping plates 15 to rotate simultaneously, thereby maintaining the two first clamping plates 15 in parallel. The first transmission member between the two second clamping plates 16 causes the two second clamping plates 16 to rotate simultaneously, thereby maintaining the two second clamping plates 16 in parallel. When the two first clamping plates 15 rotate, the gap between the two first clamping plates 15 decreases, thereby tightening the sling 27. When the two second clamping plates 16 rotate, the gap between the two second clamping plates 16 decreases, thereby tightening the sling 27.

[0036] The sides of the two first clamping plates 15 and the sides of the two second clamping plates 16 that are close to each other are both provided with an anti-slip layer to prevent the sling 27 from slipping. For example, the anti-slip layer can be an anti-slip groove. The two first clamping plates 15 can mesh with each other through the anti-slip groove, and the two second clamping plates 16 can mesh with each other through the anti-slip groove.

[0037] like Figure 7 As shown, the first transmission member includes a sprocket 10 and a chain 11. One end of the first rotating shaft 6, the second rotating shaft 7, the third rotating shaft 8, and the fourth rotating shaft 9 all pass through the extension plate 29 and are fixedly connected to the sprocket 10. The chain 11 is wound between the corresponding two sprockets 10.

[0038] A second transmission member is disposed between the first and second clamping members. The second transmission member comprises a swinging lever 12, a pull rod 13, and a driven lever 14. One end of the pull rod 13 is hinged to one end of the swinging lever 12, while the other end of the pull rod 13 is hinged to one end of the driven lever 14. The middle portion of the swinging lever 12 is fixedly connected to the second rotating shaft 7, and the end of the driven lever 14, away from the pull rod 13, is fixedly connected to the fourth rotating shaft 9.

[0039] When the sling 27 breaks, the corresponding portion of the ton bag 25 moves downward, causing the broken sling 27 to move downward. The sling 27 then drives the first clamping plate 15 below to rotate, which in turn rotates the second shaft 7. The sprocket 10 and chain 11 drive the first shaft 6 to rotate, causing the two first clamping plates 15 to rotate synchronously. This allows the two first clamping plates 15 to remain parallel and close together, clamping the sling 27 and preventing the corresponding portion of the ton bag 25 from falling further.

[0040] At the same time, the second rotating shaft 7 drives the fourth rotating shaft 9 to rotate through the swing rod 12, the pull rod 13, and the driven rod 14. The fourth rotating shaft 9 drives the third rotating shaft 8 to rotate through the sprocket 10 and the chain 11. The two second clamping plates 16 rotate synchronously, so that the two second clamping plates 16 remain parallel and approach each other, thereby clamping the sling 27 to prevent the corresponding parts of the ton bag 25 from continuing to fall.

[0041] Under the action of the two second clamping members, the two broken sections of the sling 27 are clamped, which is conducive to keeping the ton bag 25 stable, thereby maintaining the subsequent filling quality and preventing the ton bag 25 from tilting again during the subsequent filling process.

[0042] Working principle: When in use, the four slings 27 of the ton bag 25 are installed on the corresponding supporting components, specifically, as Figure 1 、 Figure 2 As shown, the sling 27 is passed between the two first clamping plates 15 and between the two second clamping plates 16. The first clamping plate 15 below supports the sling 27, and the bulk bag 25 is suspended below the movable plate 5.

[0043] Next, the filling tube 28 is placed over the raised ring 20, with its upper end extending over the funnel 19 above the raised ring 20. The electric telescopic rod 22 is activated, driving the clamping ring 23 toward the funnel 19. Once the clamping ring 23 engages the funnel 19, it compresses the upper end of the filling tube 28, forcing it firmly against the funnel 19 and preventing material from escaping through the filling tube 28 during the filling process. The material is then conveyed into the delivery tube 17, where it flows through the telescopic tube 18, the funnel 19, and the filling tube 28 into the bulk bag 25.

[0044] During the filling process, the hydraulic rod 4 is activated to reciprocate and contract, which drives the movable plate 5 to move up and down. The movable plate 5 drives the ton bag 25 to move up and down, thereby shaking the material in the ton bag 25. This helps to make the material in the middle of the ton bag 25 flow to the surrounding areas, so that the material in the ton bag 25 is filled evenly, avoids the material in the middle of the ton bag 25 being higher than the material around it, and improves the filling quality. At the same time, it helps to make the material in the ton bag 25 compact and evenly filled.

[0045] As the amount of material in the ton bag 25 increases, the tension on the sling 27 gradually increases, increasing the risk of the sling 27 breaking. When the sling 27 breaks, the corresponding portion of the ton bag 25 moves downward, unbalancing the forces on both ends of the first clamping plate 15. This causes the broken sling 27 to move downward, driving the first clamping plate 15 below to rotate, which in turn rotates the second shaft 7. The sprocket 10 and chain 11 drive the first shaft 6 to rotate. The two first clamping plates 15 rotate synchronously, bringing them closer together and clamping the sling 27, preventing the corresponding portion of the ton bag 25 from falling further.

[0046] At the same time, the second rotating shaft 7 drives the fourth rotating shaft 9 to rotate through the swing rod 12, the pull rod 13, and the driven rod 14. The fourth rotating shaft 9 drives the third rotating shaft 8 to rotate through the sprocket 10 and the chain 11. The two second clamping plates 16 rotate synchronously, thereby keeping the two second clamping plates 16 parallel and close to each other, thereby clamping the sling 27, preventing the corresponding part of the ton bag 25 from falling further. This reduces the pulling on the filling tube 28 and the funnel 19, prevents the ton bag 25 and the funnel 19 from falling, and helps prevent the escape of materials.

[0047] Under the action of the two second clamping members, the two broken sections of the sling 27 are clamped, which is conducive to keeping the ton bag 25 stable, thereby maintaining the subsequent filling quality and preventing the ton bag 25 from tilting again during the subsequent filling process.

[0048] When the second clamping plate 16 clamps the sling 27, it is in an inclined state, so that the second clamping plate 16 has a certain lifting effect on the corresponding part of the ton bag 25, which helps to compensate for the downward movement of the corresponding part of the ton bag 25. This helps to keep the ton bag 25 in a vertical state, which helps to improve the filling quality.

[0049] After filling is completed, the hydraulic rod 4 is activated to move the movable plate 5 downward, thereby allowing the ton bag 25 to fall onto the conveyor 1. After the ton bag 25 falls onto the conveyor 1, as the movable plate 5 moves downward, the sling 27 gradually loosens, making it easier to remove the sling 27 from the support assembly.

[0050] And when the ton bag 25 falls onto the conveyor 1, as the movable plate 5 moves downward, the first splint 15 and the second splint 16 corresponding to the broken sling 27 lose the effect of the ton bag 25 and reset themselves, that is, the first splint 15 returns to the horizontal state and the second splint 16 returns to the vertical state.

[0051] The present invention also includes an application of a ton bag packaging machine in the production of ammonium perchlorate, comprising the following steps: S1. Install multiple slings 27 on corresponding support assemblies respectively; pass the slings 27 on the big bag 25 through the two first clamping plates 15 and the corresponding two second clamping plates 16.

[0052] S2. Fill the material, i.e., ammonium perchlorate, into the ton bag 25 through the filling assembly.

[0053] S3. When one of the slings 27 breaks, the sling 27 moves downward, and the sling 27 drives the first clamping plate 15 to rotate. The two first clamping plates 15 rotate at the same time, and the two first clamping plates 15 clamp the sling 27. At the same time, the two second clamping plates 16 in the second clamping member rotate to clamp the sling 27. The two broken sections of the sling 27 are both clamped so that the filling work can continue.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
