Description

Technical Field

[0001] This utility model belongs to the field of packaging machine filling technology, specifically relating to a bottom-filling ton bag filling device. Background Technology

[0002] In the filling production process of food, chemical, and pharmaceutical industries, filling equipment is the core equipment. Existing filling equipment generally suffers from serious dust problems when filling powdery or fine granular materials. Ton-bag quantitative filling is designed for situations where dust is generated during material filling and where low dust concentration is required. Current common solutions include: one is to increase suction for dust removal, with the sucked-out material recycled as waste, downgraded for use, or reused in upstream equipment; strict sealing between the packaging bag and the equipment is required.

[0003] Another design involves the upper weighing mechanism rising after the packaging bag is connected to it, thereby reducing the distance between the feeding mechanism and the bottom of the packaging bag. However, since the feeding mechanism is located at the top, it needs to avoid the rising upper weighing mechanism, resulting in a relatively large distance between the feeding mechanism and the bottom of the bag. Furthermore, this design is quite complex.

[0004] Therefore, this application proposes a bottom-filling ton bag filling device to solve the above problems. Utility Model Content

It is not intended to identify key or essential parts of the invention, nor is it intended to limit its scope.

[0006] The technical solution of this utility model:

[0007] The bottom-filling ton bag filling device includes a main frame, a feeding system, an upper support mechanism, a lower support mechanism, and a lower lifting mechanism. The feeding system, the upper support mechanism, and the lower lifting mechanism are respectively installed on the main frame.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0025] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0026] Example 1, combined with Figures 1-6This embodiment describes a bottom-filling ton bag filling device, which includes a main frame 1, a feeding system 2, an upper support mechanism 3, a lower support mechanism 4, and a lower lifting mechanism 5. The main frame 1 is respectively equipped with the feeding system 2, the upper support mechanism 3, and the lower lifting mechanism 5. The lower support mechanism 4 is installed on the lower lifting mechanism 5, and the upper support mechanism 3 is arranged below the feeding system 2. The hook 6 is installed on the main frame 1 through the upper support mechanism 3. The hook 6 is used to hang the packaging bag, and the lower support mechanism 4 is used to support the packaging bag.

[0027] The packaging bag is suspended on the upper support mechanism 3 by hooks 6. Before the filling operation begins, the hydraulic cylinder 51 installed on the base 15 extends, driving the lifting frame 52 to move upward. The lifting frame 52 is connected to the guide rail 14 installed on the support rod 13. The guide rail 14 guides the lifting frame 52, ensuring its longitudinal movement. The lifting frame 52 moves upward, supporting the bottom of the packaging bag and continuing to move upward until the hydraulic cylinder 51 is fully extended. Then, the motor 21 installed on the support platform 11 is turned on, and material is input through the feed cylinder 22. The motor 21 is connected to the shaft inside the auger pipe 23, and the auger blades inside the auger pipe 23 drive the material to be continuously supplied to the discharge cylinder 25, from which it falls into the packaging bag. The motor 21, feed cylinder 22, and discharge cylinder 25 are all fixed to the support platform 11 of the main frame 1 by bolts. After filling the material for a period of time, the vibration motor 53 is turned on, which drives the support platform 41 to vibrate, leveling the material inside the packaging bag. Multiple shock absorbers 54 are also installed between the vibrating platform 55 and the lifting frame 53. The function of the shock absorbers 54 is to prevent the vibrating motor from vibrating too much and causing the supporting platform 41 to tip over. This allows the vibrating motor 53 to compact the material inside the packaging bag while maintaining a high frequency and stable vibration amplitude.

[0028] As material is continuously filled, the hydraulic cylinder 51 gradually retracts. A first sensor 31 is installed on the adjusting screw 32 used to mount the hook 6. In this embodiment, the first sensor 31 is a Gantang HZ-W1-02 force gauge, which is a 30kN force gauge. When the first sensor 31 reaches a preset weight setting value (which is less than the final package weight), the hydraulic cylinder 51 fully retracts, moving the carrying platform 41 away from the bottom of the packaging bag. Filling continues until the value of the first sensor 31 reaches the target filling weight value. The hydraulic cylinder 51 then extends again, lifting the carrying platform 41 and supporting the packaging bag while continuing to rise, removing the packaging bag hanging on the hook 6, thus completing one filling operation.

[0029] Example 2, combined with Figures 1-6This embodiment describes a bottom-filling ton bag filling device. The upper support mechanism 3's upper bracket 33 is mounted on the mounting bracket 12 of the main frame 1. Adjusting screws 32 are installed at the four corners of the upper bracket 33. A first sensor 31 is installed on the adjusting screw 32 to measure the tension of the hook 6. The adjusting screw 32 passes through the upper bracket 33 and is connected to the adjusting nut 34 at the bottom to install the hook 6 on the upper bracket 33.

[0030] The lower support mechanism 4 also has four adjustable feet 43 installed at the bottom corners of the support platform 41. The adjustable feet 43 are equipped with second sensors 42, which are RS232 tilt sensors. The level of the support platform 41 is adjusted by the second sensors 42 in conjunction with the adjustable feet 43 to ensure that the support platform 41 is in a stable state.

[0031] Example 3, combined with Figures 1-2 This embodiment describes a bottom-filled ton bag filling device. A vent pipe 24 is also installed on the discharge cylinder 25. The vent pipe 24 serves two purposes: firstly, it facilitates the cleaning of residual material inside the discharge cylinder 25; after filling, high-pressure gas is introduced into the discharge cylinder 25 through the vent pipe 24 for cleaning; secondly, it ensures airflow within the discharge cylinder 25 during the filling process, preventing problems such as excessive material moisture causing clumping.

[0032] Example 4, combined with Figures 1-2 In this embodiment, the bottom-filling ton bag filling device is equipped with a spare input pipe 7 on the mounting frame 12. The spare input pipe 7 can be directly connected to the discharge cylinder 25 through a pipeline. Materials can be input into the discharge cylinder 25 through the spare input pipe 7, or when it is necessary to mix materials in proportion, the materials can be input through the spare input pipe 7.

[0033] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
