Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, and in particular to a combined structure for a rotary packaging machine. Background Technology

[0002] In modern industrial production, the large-scale packaging of powdery or granular materials (such as flour, clay, stone powder, and mineral powder) places higher demands on the automation, stability, and efficiency of packaging equipment. Especially in industries such as building materials, food, and chemicals, the characteristics of the materials (such as high dust levels, poor flowability, and bridging) pose challenges to the structural layout, weighing accuracy, filling stability, and sealing performance of the packaging system. While commonly used rotary packaging equipment can meet certain continuous packaging needs, it generally suffers from problems such as fragmented structural layout, low equipment integration, inconvenient maintenance and operation, and a lack of unified interfaces between the power and control system modules. Furthermore, the lack of unified planning in the system's upper and lower structures and the chaotic connection methods between different modules lead to poor overall machine stability and long-term maintenance performance. Particularly when facing the need to switch between different material types or rapidly adjust production lines, the rigidity and coupling of traditional equipment structures often result in low efficiency or inability to adapt, severely restricting its application expansion under various working conditions.

[0003] Existing rotary packaging machines mostly adopt a horizontally distributed and modular construction method, where functional units (such as bag making, bag insertion, weighing, feeding, filling, and sealing) are scattered around the perimeter of the equipment or on separate supports, failing to form a unified modular architecture. This traditional approach has several problems: First, it requires a large footprint, has long material paths, and high system energy consumption, hindering the simplification of production line layouts; second, precise coordination of equipment operation is difficult, requiring complex synchronization control strategies between modules; third, the structural hierarchy is unclear, making inspection and maintenance inconvenient. For example, the weighing platform or feeding pipes at the top need to be disassembled and reassembled via external ladders or lifting devices, increasing operation and maintenance costs. Furthermore, in high-dust environments, the externally open structure is more prone to equipment contamination and control system malfunctions. Overall, the traditional packaging machine structure fails to meet the urgent needs of modern industry for highly integrated, highly versatile, scalable, and easy-to-maintain packaging equipment. Utility Model Content

[0004] This utility model discloses a modular structure for a rotary packaging machine. During operation, materials are conveyed from the top through multiple pipes to a multi-station small hopper in the middle layer for rotary filling. The lower layer completes bag preparation, insertion, sealing, and finished product output. A cleaning and recycling device simultaneously handles residual material and dust, improving cleanliness and sealing reliability. The control system coordinates the actions of each module to achieve automated, continuous, and high-capacity packaging of powdered or granular materials. This compact and efficient structure is suitable for the automated packaging needs of various materials in industries such as building materials, chemicals, and grains, thus solving the problems in the background technology.

The material conveying device quantitatively transports bulk materials to the upper feeding system, ensuring that materials are evenly distributed into the multiple small hoppers within the rotary filling device. The filling device, driven by a servo, achieves multi-station cyclic filling, greatly improving packaging efficiency. The bag making device continuously prepares standard bags from the film roll and delivers them below the filling port. The bag inserting device… The system works in conjunction with positioning sensors to accurately align the bag and prepare for opening; after filling, the sealing device immediately performs heat sealing and cooling to ensure a reliable seal; the cleaning and recycling device collects any spilled residual material to keep the equipment clean and extend its service life; finally, the discharge conveyor smoothly delivers the finished bag out of the equipment for subsequent stacking or logistics processes; through mechanical linkage and coordinated operation of the control system, the various functional modules achieve automation, continuity, and high reliability in the packaging process, effectively overcoming the technical bottlenecks of traditional packaging equipment such as loose structure, low efficiency, and difficult maintenance.

[0027] Reference Figures 1-8 A combined structure for a rotary packaging machine includes a material conveying device 1, a rotary filling device 2, a bag making device 3, a bag inserting device 4, a sealing device 5, a cleaning and recycling device 6, and a discharge conveying device 7. The material conveying device 1 is located at the top of the equipment and is connected to a multi-tube distributor through the main material bin. The rotary filling device 2 is located below the material conveying device 1. The bag making device 3 is located on one side of the rotary filling device 2. The bag inserting device 4 and the sealing device 5 are both located outside the rotary filling device 2. The cleaning and recycling device 6 is located at the bottom of the rotary filling device 2, and the discharge conveying device 7 is located at the bottom of the equipment.

[0028] The rotary filling device 2 consists of a central rotating platform 201 and eight small hoppers 202 arranged circumferentially. The rotary filling device 2 includes a servo motor 203, a gearbox 204, and a main shaft connecting flange 205. The rotary filling device 2 is connected to the lower rotary platform through a central shaft 206. Each small hopper 202 is independently enclosed. The bag making device 3 uses roll film feeding. The bag making device 3 includes a roll film support 301, a heat sealing module 302, a bag cutting unit 303, and a bag pulling arm 304. The bag inserting device 4 is equipped with a pneumatic gripper 401. The sealing device 5 is equipped with a double heating strip heat sealing machine. The cleaning and recycling device 6 includes a negative pressure dust collection device 601 and a dust collection box. The discharge conveying device 7 has positioning slide rails on both sides.

[0029] In the specific implementation process, the material conveying device 1 adopts the screw conveyor method to continuously transport bulk materials from the main material silo to the upper feeding platform. The feeding platform is equipped with several guide ports, which correspond one-to-one with the eight small material silos 202 in the lower rotary filling device 2. The opening and closing sequence of each discharge port is precisely controlled by an electric ball valve to achieve synchronous and uniform material distribution, avoid material blockage and uneven weighting, and improve filling consistency.

[0030] The high-speed magnetic encoder of the rotary filling device 2 is installed on the rotating shaft to detect the platform angle and achieve precise indexing of the filling station; the central rotating platform 201 is driven by the upper servo motor 203 and achieves indexing rotation through the central shaft 206. Each rotation makes a small material bin 202 face the filling station below. The bottom of the small material bin 202 is equipped with a pneumatically controlled discharge valve, which opens after the bag body is fixed by the corresponding bag insertion device 4, and accurately feeds material according to the set amount. This structure can support eight independent packaging lines to operate in parallel, which greatly improves the overall production capacity.

[0031] When the bag making device 3 is working, the packaging film material is flattened and heat-sealed to form a cylindrical bag body through the cooperation between the film roll bracket 301, the heat sealing module 302 and the bag cutting unit 303. Then, it is cut to a set length to form a standard bag body. A suction cup bag pulling mechanism is set up to generate negative pressure using a vacuum generator. With the help of the bag pulling arm 304, the bag body is reliably adsorbed and pushed to the bag insertion station, waiting for the bag insertion mechanism to further align and open.

[0032] The bag insertion device 4 uses a pneumatic clamp 401 to fix the bag body sent by the bag making device 3 below the feeding port. The system is equipped with a position detection sensor to ensure that the bag opening is aligned with the hopper. At the same time, the bag body is opened to prevent tilting or wrinkling during filling. After the bag insertion is completed, the upper small hopper 202 is triggered to automatically feed the material to achieve quantitative filling.

[0033] After the bag is filled, it is transferred to the sealing device 5 by the gripper. The sealing device 5 clamps the bag mouth and heats and melts it. Then it immediately enters the cooling zone and is shaped and fixed by cold air or cold plate to ensure that the seal is firm, flat and does not leak powder. The device is equipped with a heat protection cover and temperature control protection to improve the safety of operation.

[0034] The cleaning and recycling device 6 can be used in conjunction with the negative pressure dust collection device 601 and the dust collection box to specifically recover dust and loose materials generated during the filling process due to vibration or material splashing. It can be cleaned regularly or connected to a centralized recycling system to effectively prevent equipment from accumulating dust, clogging and contaminating the packaging bag sealing area, thereby improving equipment cleanliness and yield.

[0035] The discharge conveyor 7 is a horizontal conveyor belt system at the bottom of the equipment. It receives the sealed finished bags and transports them to the external workstation. The positioning slide rails on both sides can ensure the stable movement of the bags and prevent them from falling or overturning.

[0036] In summary, this utility model integrates material conveying, rotary filling, bag making, bag insertion, sealing, cleaning and discharging functional modules through a three-layer structure, forming a vertically coordinated and highly efficient automatic packaging system. The material is conveyed from the top to multiple rotating hoppers for quantitative distribution, and the bag body is simultaneously prepared below and automatically inserted for alignment. After filling, heat sealing and cooling, the bag is output by the conveying device, and each module is reset to complete the rotary filling task.
