Description

Technical Field

[0001] This utility model relates to the technical field of ton bag compaction equipment, and in particular to a vacuum shaping and compaction equipment for ton bag materials. Background Technology

[0002] In the storage and transportation of powdery and granular materials (such as chemical raw materials, grains, minerals, etc.), ton bags (or flexible container bags, FIBCs) are widely used because of their large capacity (usually holding 500-2000 kg), ease of use, and relatively low cost.

[0003] However, the materials inside ton bags often suffer from looseness, fluffiness, and uneven distribution during filling or transportation, resulting in large bag volumes and irregular shapes. This not only occupies a large amount of storage and transportation space and increases logistics costs, but also leads to poor stacking stability and safety hazards. To solve this problem, vacuum shaping and compaction equipment has emerged. The core principle of this type of equipment is to place the ton bag containing loose materials in a sealed chamber, and use a vacuum system to remove the air from the bag and the chamber. Atmospheric pressure is then used to apply uniform pressure to the ton bag as a whole, thereby compressing the material volume, straightening the bag shape, improving stacking stability, and increasing space utilization.

[0004] However, existing vacuum shaping and compaction equipment still has significant technical defects in practical applications: the equipment generally lacks a structure that effectively constrains the ton bag during the vacuum compression process, which makes the ton bag prone to irregular and severe deformation, twisting or even displacement under vacuum negative pressure. This not only affects the final compaction and shaping effect (such as uneven bag surface and uneven material distribution), but may also cause ton bag damage or equipment sealing failure.

[0005] Therefore, how to provide a vacuum shaping and compaction device for ton bag materials is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide a vacuum shaping and compaction device for ton bag materials, which solves the problems mentioned in the background art.

[0007] A vacuum shaping and compaction device for ton bag materials according to an embodiment of the present invention includes a ton bag body and a base. A rotating adjustment component is provided at the bottom of the inner wall of the base, and a tightening plate is provided at the top of the rotating adjustment component. A driving rod is rotatably connected to the top of the tightening plate near the side. A base plate is fixedly connected to the top of the base. A guide groove is opened on the surface of the base plate to align the upper and lower surfaces of the base plate. A side limiting component is movably connected inside the guide groove. The end of the driving rod away from the tightening plate is rotatably connected to the bottom of the side limiting component.

[0008] The rotating adjustment component includes a support base, a rotating worm gear, and a worm. The support base is fixedly connected to the bottom of the inner wall of the base, the rotating worm gear is fixedly connected to the lower surface of the turntable, the tightening disc is rotatably connected to the top of the support base, and the worm is fixedly installed on the inner wall of the support base through a mounting seat. The worm and the worm gear mesh with each other.

[0009] The rotary adjustment component also includes a rotating shaft and a knob. The rotating shaft is fixedly connected to one end face of the worm gear, and the other end of the rotating shaft extends to the outside of the base. The end of the rotating shaft located outside the base is fixedly connected to the knob.

[0010] The turntable is rotatably connected to the top of the support base via a tapered bearing.

[0011] The number of driving rods is four sets, and the number and position of the side limiting parts match the number and position of the driving rods.

[0012] The side limiting component includes a slide block and a limiting rod. The slide block is slidably connected inside the guide groove, and the limiting rod is vertically fixedly connected to the top of the slide block. The inner side of the limiting rod is movably connected to the surface of the ton bag.

[0013] The beneficial effects of this utility model are:

[0014] The worm gear mechanism can be driven by manually rotating the knob, which precisely controls the synchronous retraction or expansion of the four sets of side limiters, enabling rapid positioning and clamping of the ton bag. The operation is simple and labor-saving. The limit rod saves space through the vertical movement design of the guide groove, and can directly conform to the surface of the ton bag, adapting to the shaping needs of ton bags of different sizes. No additional power source is required, making it widely applicable.

[0015] The worm gear meshing structure has a reverse self-locking characteristic, which can automatically lock the position after adjustment, ensuring that the side limit component will not loosen due to the expansion force of the material during vacuum shaping, thus ensuring shaping stability.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-4 In this embodiment, the bag includes a ton bag body 1 and a base 2. A rotating adjustment component 3 is provided at the bottom of the inner wall of the base 2. The rotating adjustment component 3 includes a support seat 9, a rotating worm gear 10, and a worm 11. The support seat 9 is fixedly connected to the bottom of the inner wall of the base 2. The rotating worm gear 10 is fixedly connected to the lower surface of the turntable. The tightening disc 4 is rotatably connected to the top of the support seat 9. The worm 11 is fixedly installed on the inner wall of the support seat 9 through a mounting seat. The worm 11 meshes with the worm gear. The top of the rotating adjustment component 3 is provided with a tightening disc 4. A driving rod 5 is rotatably connected to the top of the tightening disc 4 near the side. There are four sets of driving rods 5.

[0024] refer to Figure 1-4 In this embodiment, the rotating adjustment component 3 also includes a rotating shaft 12 and a knob 13. The rotating shaft 12 is fixedly connected to one end face of the worm gear 11, and the other end of the rotating shaft 12 extends to the outside of the base 2. The end of the rotating shaft 12 located outside the base 2 is fixedly connected to the knob 13. The turntable is rotatably connected to the top of the support seat 9 through a tapered bearing.

[0025] refer to Figure 1-4 In this embodiment, a base plate 6 is fixedly connected to the top of the base 2. A guide groove 7 is provided on the surface of the base plate 6 to connect the upper surface and the lower surface of the base plate 6. A side limiting member 8 is movably connected inside the guide groove 7. The number and position of the side limiting members 8 are matched with the number and position of the driving rods 5. The end of the driving rod 5 away from the tightening plate 4 is rotatably connected to the bottom of the side limiting member 8.

[0026] refer to Figure 1-4In this embodiment, the side limiting member 8 includes a slide 14 and a limiting rod 15. The slide 14 is slidably connected inside the guide groove 7, and the limiting rod 15 is vertically fixedly connected to the top of the slide 14. The inner side of the limiting rod 15 is movably connected to the surface of the ton bag.

[0027] The working principle of this utility model is as follows:

[0028] When the operator rotates the knob 13 located outside the base 2, the rotating shaft 12 fixed to the knob 13 drives the worm gear 11 to rotate, and the worm gear 11 drives the rotating worm wheel 10 meshing with it to rotate; since the rotating worm wheel 10 is fixed to the bottom of the turntable, the turntable rotates on the top of the support 9 through the conical bearing, driving the tightening disc 4 on its top to rotate synchronously; the four sets of driving rods 5 hinged to the edge of the tightening disc 4 move accordingly, converting the rotation of the tightening disc 4 into a horizontal pushing / pulling force; the other end of the driving rod 5 is hinged to the bottom of the slide 14 of the side limiting member 8, forcing the slide 14 to move. 4. The guide 7 is pre-set along the base plate 6, thereby driving the limiting rod 15, which is vertically fixed to the top of the slide block 14, to retract towards the center or expand outward. When the limiting rod 15 retracts, it is in close contact with the side wall of the ton bag, forming a stable circumferential constraint. In the subsequent vacuum pumping, shaping and compaction process, the limiting rod 15 resists the expansion force of the material and maintains the shape of the ton bag. At the same time, the self-locking characteristic of the worm gear 11 prevents the limiting rod 15 from retracting, while the tapered bearing at the bottom of the turntable bears the shaping pressure, ensuring that the overall structure operates stably under load, and finally achieving efficient compaction and shaping of the ton bag material.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
