DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] As shown in Figures 1-11 , the technical solutions adopted by the present application are as follows: a ton bag packaging machine comprises a conveying piece 1, a mounting plate 3, a moving plate 5 and a support assembly. The conveying piece 1 is used for conveying the ton bag 25. The support rods 2 are fixed on both sides of the conveying piece 1, and the mounting plate 3 is fixedly connected with the upper ends of the support rods 2. The mounting plate 3 is arranged above the conveying piece 1.​​

[0039] The moving plate 5 is arranged below the mounting plate 3 and moves up and down. Specifically, as shown in Figure 1 , the top of the mounting plate 3 is fixedly provided with a plurality of hydraulic rods 4. The telescopic ends of the hydraulic rods 4 are fixedly connected with the moving plate 5 after penetrating the mounting plate 3 vertically downward. The arrangement of the plurality of hydraulic rods 4 is conducive to stably supporting the moving plate 5.

[0040] During the filling process, the ton bag 25 is hung on the moving plate 5, and the moving plate 5 is driven by the hydraulic rods 4 to move up and down reciprocally, so as to make the ton bag 25 move up and down reciprocally, which is conducive to improving the uniformity of the filling of the material in the ton bag 25.

[0041] The moving plate 5 is provided with a filling assembly, and the filling assembly is used to fill the material into the conveying member 1. As shown in Figure 1 , Figure 4 , Figure 5 , Figure 9 , Figure 10 , the filling assembly comprises a material conveying pipe 17, a telescopic pipe 18 and a funnel 19. One end of the material conveying pipe 17 is fixedly arranged on the upper end surface of the mounting plate 3. One end of the telescopic pipe 18 is fixedly connected with the mounting plate 3 and communicates with the material conveying pipe 17, and the other end of the telescopic pipe 18 is fixedly connected with the moving plate 5 and communicates with the funnel 19. The upper end of the funnel 19 is fixedly arranged on the moving plate 5. The lower end of the funnel 19 is fixedly provided with a convex ring 20. The moving plate 5 is provided with a fixing member for fixing the ton bag 25 to the funnel 19.

[0042] In this embodiment, the fixing member comprises an electric telescopic rod 22 and a clamping ring 23. The lower end of the moving plate 5 is fixedly provided with two fixed plates 21, and each fixed plate 21 is provided with an electric telescopic rod 22 arranged horizontally. The telescopic end of each electric telescopic rod 22 is connected with a clamping ring 23. The clamping ring 23 is arc-shaped and adapted to the funnel 19. The side of the clamping ring 23 close to the funnel 19 is provided with a rubber ring 24.

[0043] In this embodiment, the cross section of the ton bag 25 is square, and the connecting part of the adjacent sides of the ton bag 25 is provided with an edge sealing 26. The upper end surface of the ton bag 25 is provided with four lifting belts 27. The upper end surface of the ton bag 25 is provided with a filling pipe 28.

[0044] In use, the ton bag 25 is hung below the moving plate 5 through the support assembly. And the funnel 19 is communicated with the ton bag 25. Specifically, the filling pipe 28 is sleeved on the convex ring 20 and the upper end of the filling pipe 28 is stretched above the convex ring 20, then the electric telescopic rod 22 is started, the clamping ring 23 is driven by the electric telescopic rod 22 to approach the funnel 19, and the two clamping rings 23 are clamped on the funnel 19 above the convex ring 20. The clamping ring 23 extrudes the funnel 19 through the rubber ring 24, so that the upper end of the filling pipe 28 is tightly combined with the funnel 19, and the material in the filling process is prevented from escaping through the upper end of the filling pipe 28.

[0045] The lower end of the moving plate 5 is fixedly provided with four extension plates 29, each of which is installed with a support assembly. The four support assemblies correspond to the four lifting belts 27 one by one, the lifting belts 27 are installed on the corresponding support assemblies, and then the ton bag 25 is hung below the moving plate 5.

[0046] Each support assembly comprises a first clamping piece and two second clamping pieces. As shown in Figure 4 , the second clamping piece has two, and one of the second clamping pieces is arranged on one side below the first clamping piece, and the other second clamping piece is arranged on the other side below the first clamping piece.

[0047] As shown in Figure 6 , Figure 7 , the first clamping piece comprises two first clamping plates 15 which are parallel to each other. The first clamping plate 15 is rotationally arranged on the extension plate 29. Specifically, the middle part of one of the first clamping plates 15 is fixedly connected with a first rotating shaft 6, and the other first clamping plate 15 is fixedly connected with a second rotating shaft 7. The second rotating shaft 7 is arranged below the first rotating shaft 6. The first rotating shaft 6 and the second rotating shaft 7 are rotationally connected with the extension plate 29. In the normal state, the first clamping plate 15 is in the horizontal state, at this time, the two first clamping plates 15 have a gap between them.

[0048] Each second clamping piece comprises two second clamping plates 16 which are parallel to each other. The second clamping plate 16 is rotationally installed on the extension plate 29. Specifically, one of the second clamping plates 16 is fixedly connected with a third rotating shaft 8, and the other second clamping plate 16 is fixedly connected with a fourth rotating shaft 9, both the third rotating shaft 8 and the fourth rotating shaft 9 are rotationally installed on the extension plate 29. And the third rotating shaft 8 and the fourth rotating shaft 9 are arranged on the upper part of the second clamping plate 16. In the normal state, the second clamping plate 16 is in the vertical state, at this time, the two second clamping plates 16 have a gap between them.

[0049] 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 piece. The lower first clamping plate 15 supports the lifting belt 27.

[0050] In this embodiment, in order to facilitate the installation of the sling 27 to the support assembly, the first clamping plates 15 and the second clamping plates 16 are arranged on the side of the extension plate 29 away from the funnel 19.

[0051] The first transmission members are arranged between the two first clamping plates 15 and between the two second clamping plates 16 in the same second clamping member. The first transmission members between the two first clamping plates 15 enable the two first clamping plates 15 to rotate simultaneously and thus keep the two first clamping plates 15 parallel. The first transmission members between the two second clamping plates 16 enable the two second clamping plates 16 to rotate simultaneously and thus keep the two second clamping plates 16 parallel. When the two first clamping plates 15 rotate, the gap between the two first clamping plates 15 becomes smaller, and thus the sling 27 is clamped. When the two second clamping plates 16 rotate, the gap between the two second clamping plates 16 becomes smaller and thus the sling 27 is clamped.

[0052] The side of the two first clamping plates 15 close to each other and the side of the two second clamping plates 16 close to each other are provided with anti-skid layers to prevent the sling 27 from slipping off. For example, the anti-skid layers can be anti-skid grooves. The two first clamping plates 15 can be engaged with each other through the anti-skid grooves, and the two second clamping plates 16 can be engaged with each other through the anti-skid grooves.

[0053] As shown in FIG. 1, Figure 7 The first transmission members include sprockets 10 and chains 11. One end of each of the first rotating shaft 6, the second rotating shaft 7, the third rotating shaft 8, and the fourth rotating shaft 9 penetrates the extension plate 29 and is fixedly connected with a sprocket 10. The chains 11 are wound between the corresponding two sprockets 10.

[0054] The second transmission members are arranged between the first clamping member and the second clamping member. The second transmission members include swing rods 12, pull rods 13, and driven rods 14. One end of each of the pull rods 13 is hingedly connected with one end of each of the swing rods 12, and the other end of each of the pull rods 13 is hingedly connected with one end of each of the driven rods 14. The middle part of each of the swing rods 12 is fixedly connected with the second rotating shaft 7, and the end of each of the driven rods 14 away from the pull rod 13 is fixedly connected with the fourth rotating shaft 9.

[0055] When the sling 27 breaks, the corresponding part of the ton bag 25 moves downward, causing the broken sling 27 to move downward. The sling 27 drives the lower first clamping plate 15 to rotate, and the second rotating shaft 7 rotates. The first rotating shaft 6 is driven to rotate through the sprockets 10 and the chains 11. The two first clamping plates 15 rotate synchronously, and thus the two first clamping plates 15 keep parallel while moving close to each other, clamping the sling 27 and preventing the corresponding part of the ton bag 25 from continuing to fall.

[0056] Meanwhile, 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, and the two second clamping plates 16 rotate synchronously, so that the two second clamping plates 16 keep parallel and approach each other, thereby clamping the sling 27 and preventing the ton bag 25 from falling off.

[0057] Under the action of the two second clamping plates, the two sections of the broken sling 27 are clamped. This is beneficial to keep the ton bag 25 stable, thereby keeping the subsequent filling quality and avoiding the ton bag 25 from tilting again in the subsequent filling process.

[0058] Working principle:

[0059] In use, the four slings 27 of the ton bag 25 are installed on the corresponding support assemblies. Specifically, as shown in Figure 1 、 Figure 2 the slings 27 are passed between the two first clamping plates 15 and the two second clamping plates 16. The lower first clamping plate 15 supports the sling 27, and the ton bag 25 is hung below the moving plate 5.

[0060] Then, the filling pipe 28 is sleeved on the convex ring 20, and the upper end of the filling pipe 28 is stretched to the hopper 19 above the convex ring 20. The electric telescopic rod 22 is started, and the clasp ring 23 is moved close to the hopper 19. Until the clasp ring 23 is clamped on the hopper 19, the clasp ring 23 extrudes the upper end of the filling pipe 28, so that the upper end of the filling pipe 28 is tightly attached to the hopper 19, preventing the material from escaping through the filling pipe 28 during filling. Then the material is transported into the material conveying pipe 17, and the material in the material conveying pipe 17 flows into the ton bag 25 through the telescopic pipe 18, the hopper 19 and the filling pipe 28.

[0061] During the filling process, the hydraulic rod 4 is started, and the hydraulic rod 4 is reciprocally contracted and expanded, so that the moving plate 5 moves up and down reciprocally, and the ton bag 25 moves up and down reciprocally, so as to shake the material in the ton bag 25. This is beneficial to make the material in the middle of the ton bag 25 flow to the periphery, so as to make the material in the ton bag 25 fill uniformly, avoid the material in the middle of the ton bag 25 being higher than the material around, and improve the filling quality. Meanwhile, this is beneficial to make the material in the ton bag 25 fill tightly and uniformly.

[0062] With the increase of the material in the ton bag 25, the tension of the sling 27 gradually increases, thereby increasing the risk of the sling 27 breaking. When the sling 27 breaks, the corresponding part of the ton bag 25 moves downward, and the force on both ends of the first clamping plate 15 is unbalanced. The broken sling 27 moves downward, and the first clamping plate 15 below the sling 27 rotates, and the second rotating shaft 7 rotates. The first rotating shaft 6 is driven to rotate through the chain wheel 10 and the chain 11. The two first clamping plates 15 rotate synchronously, so that the two first clamping plates 15 approach each other, thereby clamping the sling 27, preventing the corresponding part of the ton bag 25 from continuing to fall.

[0063] 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, and the third rotating shaft 8 is driven to rotate through the chain wheel 10 and the chain 11. The two second clamping plates 16 rotate synchronously, thereby making the two second clamping plates 16 approach each other while keeping parallel, thereby clamping the sling 27, preventing the corresponding part of the ton bag 25 from continuing to fall. Reduce the pulling of the filling pipe 28 and the hopper 19, prevent the ton bag 25 from falling off the hopper 19, and facilitate preventing the material from escaping.

[0064] Under the action of the two second clamping pieces, the two broken slings 27 are clamped. It is beneficial to keep the ton bag 25 stable, thereby keeping the subsequent filling quality, and avoiding the ton bag 25 from tilting again in the subsequent filling process.

[0065] And 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 is beneficial to compensate for the distance of the corresponding part of the ton bag 25 moving downward. Further, it is beneficial to keep the ton bag 25 in a vertical state, and is beneficial to improve the filling quality.

[0066] After the filling is completed, the hydraulic rod 4 is started, the moving plate 5 is lowered, and the ton bag 25 falls onto the conveying piece 1. After the ton bag 25 falls onto the conveying piece 1, the sling 27 gradually relaxes as the moving plate 5 moves downward, which facilitates the removal of the sling 27 from the support assembly.

[0067] And when the ton bag 25 falls onto the conveying piece 1, the first clamping plate 15 and the second clamping plate 16 corresponding to the broken sling 27 reset after losing the action of the ton bag 25, that is, the first clamping plate 15 returns to the horizontal state, and the second clamping plate 16 returns to the vertical state.

[0068] The application also includes an application of a ton bag packaging machine in the production of ammonium perchlorate, including the following steps:

[0069] S1, install a plurality of slings 27 on the corresponding support assemblies respectively; pass the sling 27 on the ton bag 25 between the two first clamping plates 15 and the corresponding two second clamping plates 16.

[0070] S2, filling the material, i.e. ammonium perchlorate, into the ton bag 25 through the filling assembly.

[0071] S3, when one of the sling belts 27 breaks, the sling belt 27 moves downward, the first clamping plates 15 are rotated by the sling belt 27, the two first clamping plates 15 rotate simultaneously, and the two first clamping plates 15 clamp and fix the sling belt 27; meanwhile, the two second clamping plates 16 in the second clamping member rotate to clamp the sling belt 27; thus, the two broken sling belts 27 are clamped, so that the filling work can continue.

[0072] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
