Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging machines, in particular to a multi-column high-speed four-edge powder bag packaging machine. BACKGROUND

[0002] The powder bag packaging machine is a kind of automatic packaging equipment widely used in food, medicine, health care products and chemical industry, etc. Its main function is to distribute the powder material into the bag according to the set dose, and form a four-edge sealed bag through heat sealing or cold sealing process. With the increasing demand for small packaging powder products in the market, multi-column high-speed powder bag packaging machines have gradually become the mainstream equipment form, which can realize multi-column parallel production in limited space and significantly improve production efficiency.

[0003] In the prior art, the Chinese patent document with publication number CN118419321A, a double-coating processing device based on slow-release compound feed additive, is proposed by setting a discharge hopper, a stripping mold and an auxiliary block. The semi-circular design of the discharge hopper can effectively guide the material flow in the mixing hopper to the film coating mold, ensuring that the material accurately enters the coating process and avoiding material overflow or accumulation. The film coating mold is set in an inverted triangular shape, matching the shape of the discharge hopper, which can ensure the smooth wrapping of the film coating during the coating process and avoid misplacement or folding of the film coating, improving the quality of the coating. However, like traditional methods, the traditional equipment lacks effective mechanical interlocking mechanisms, and the feeding path usually relies on simple valves or manual switching operations, which can easily cause material residue and mixing, leading to cross-contamination, affecting product hygiene safety and quality consistency. This problem is particularly prominent in high-demand industries such as food and medicine, increasing the risk of quality and market recall. Secondly, in terms of cleaning and maintenance, the traditional design cleaning process often requires complete shutdown, relying on manual disassembly and washing or simple flushing, which cannot be staggered with production timing, resulting in a significant decrease in equipment utilization, frequent production interruptions, and incomplete cleaning, which can cause blockage, deterioration or bacterial growth due to residual powder, further increasing equipment wear and failure rate and maintenance costs.

[0036] As Figures 1 to 10As shown, the multi-column high-speed four-edge powder strip bag packaging machine comprises a plurality of support frames 1, each of which is provided with a box body 2, the top surface of the box body 2 is provided with a stirring feeding bin 3 and a film feeding frame 4, the top of one side of the box body 2 is provided with a heat sealing mechanism 5, the middle of one side of the box body 2 is provided with a flat mouth cutting frame 6, the bottom of one side of the box body 2 is provided with a discharging guide disc 7, and a tension roller 8 is further arranged between the heat sealing mechanism 5 and the flat mouth cutting frame 6, which is used to pull the strip film on the film feeding frame 4; an interlocking shunt assembly is arranged at the top middle of the box body 2, one side of the interlocking shunt assembly is communicated with the bottom of the stirring feeding bin 3, the interlocking shunt assembly is driven by material flow pressure and performs double-way interlocking switching, a discharging pipe 20 is arranged at the bottom of the interlocking shunt assembly, which is used to feed powder; a staggered cleaning assembly is arranged on one side of the box body 2, which is communicated with the other side of the interlocking shunt assembly and is used to clean at different times after feeding and before next feeding, wherein the heat sealing mechanism 5 comprises two fixed plates 9 fixedly installed on both sides of the box body 2, the two fixed plates 9 are oppositely arranged, two guide columns 11 are arranged on the two fixed plates 9, movable plates 12 are movably installed on the opposite surfaces of the two fixed plates 9, the two movable plates 12 are slidably installed on the guide columns 11, the opposite surfaces of the two movable plates 12 are provided with two first heat sealing columns 13, and the bottom of the opposite surface of the movable plate 12 is provided with a second heat sealing column 14, the first heat sealing column 13 is used to seal the two side edges of the strip, and the second heat sealing column 14 is used to seal the upper and lower edges of the strip;

[0037] The powder in the stirring feeding bin 3 enters the interlocking shunt assembly under gravity or auxiliary conveying; the assembly automatically performs logical actions under the drive of material flow pressure - when the main powder flow passes, its pressure pushes the internal valve core to move, on the one hand, to open the passage to the column below the discharge pipe 20, and on the other hand, to mechanically lock the standby passage to the staggered cleaning assembly, thereby realizing the continuous supply of pure powder; the powder is uniformly filled onto the strip film drawn out from the film feeding frame 4 through the discharge pipe 20; the strip film smoothly passes through the heat sealing mechanism 5 under the continuous traction of the tension roller 8 at a constant tension; at this time, the cylinder 10 acts according to the preset program, pushes the movable plate 12 to slide accurately along the guide column 11, and simultaneously pushes the first heat sealing column 13 and the second heat sealing column 14 installed on the movable plate 12 to press against the film material; the first heat sealing column 13 efficiently seals the two longitudinal sides of the strip to form a continuous bag cylinder, while the second heat sealing column 14 seals the bottom edge of each bag immediately after, leaving the top surface to receive the powder material, and then continues to pull down, the second heat sealing column 14 simultaneously seals the top of the already bagged bag and the bottom of the unbagged bag, thereby efficiently and reliably completing the four-edge sealing to form individual sealed packaging bags; after heat sealing, the film strip continues to be pulled to the flat cutting frame 6, and the cutting blade cuts the continuous bag cylinder into single finished bags; finally, the finished bags are orderly guided out and collected through the discharge guide disc 7; during the intermittent period of the entire production cycle or before the production is changed, the staggered cleaning program can be triggered - the interlocking shunt assembly switches the passage, and cleaning liquid or high-pressure airflow flows from the staggered cleaning assembly to reversely flush the pipeline, valve cavity and discharge nozzle that have just conveyed the powder, and all residues are directly blown into the former area or a special collection port that has not yet been filmed, thereby realizing seamless connection and non-interference between production and cleaning; this process is closely linked, and the whole process reflects high automation and synergy.

[0038] As shown in Figures 3 to 8 The interlocking shunt assembly includes a shunt pipe 16 fixedly installed at the top middle part of the box 2, a first feeding pipe 17 arranged on one side of the shunt pipe 16, a second feeding pipe 18 arranged on the other side of the shunt pipe 16, a discharge pipe 19 arranged at the middle bottom of the shunt pipe 16, a discharge pipe 20 opposite to the discharge pipe 19, a communication pipe 15 arranged at the bottom of the stirring feeding bin 3, the communication pipe 15 being in communication with the first feeding pipe 17, a positioning frame 21 arranged at the inner top of the shunt pipe 16, the positioning frame 21 being arranged in a door shape, a sliding rod 22 slidably installed at the bottom of the positioning frame 21, a blocking piece 23 fixedly sleeved on both sides of the sliding rod 22, the blocking piece 23 being used for blocking the first feeding pipe 17 or the second feeding pipe 18, in the initial state, the first feeding pipe 17 is arranged in the blocking state, and the second feeding pipe 18 is arranged in the normally open state, a limiting block 24 fixedly sleeved on the middle part of the sliding rod 22, a reset spring 25 arranged at both ends of the limiting block 24, the reset spring 25 movably sleeving the outer surface of the sliding rod 22, and the other ends of the two reset springs 25 being connected with the bottom sides of the positioning frame 21, respectively.

[0039] The powder in the stirring feeding bin 3 enters the first feeding pipe 17 of the interlocking shunt assembly through the connecting pipe 15 under gravity or auxiliary conveying; in the initial state, the sliding rod 22 is in a specific position due to the pre-tightening force of the return spring 25, so that the blocking piece 23 blocks the first feeding pipe 17, and the second feeding pipe 18 remains open; when the powder starts to flow and generates sufficient pressure, the fluid pressure acts on the blocking piece 23 at one end of the sliding rod 22, pushing the sliding rod 22 to move axially while compressing the return spring 25 on one side; the movement of the sliding rod 22 drives the synchronous displacement of the blocking piece 23 thereon, thereby unblocking the first feeding pipe 17 and blocking the second feeding pipe 18 instead, realizing automatic switching of the route; at this time, the powder flow smoothly enters the main body of the shunt pipe 16 through the first feeding pipe 17, and is finally discharged from the discharge pipe 19 and accurately conveyed to the packaging station through the discharge pipe 20; when the stirring feeding bin 3 stops feeding and the fluid pressure disappears, the compressed return spring 25 releases the stored energy, pushing the sliding rod 22 and the blocking piece 23 to accurately return to the initial position, re-blocking the first feeding pipe 17 and opening the second feeding pipe 18, preparing for the next feeding or standby operation (such as cleaning liquid injection); the whole process is automatically operated without external control instructions, and the pure mechanical interlocking feature ensures the absolute synchronization and precision of the switching action, eliminating the risk of double-path simultaneous feeding, while the spring return mechanism guarantees high response speed and repeated positioning accuracy of the system, thereby improving production efficiency, greatly ensuring product safety and quality consistency, and significantly reducing energy consumption and maintenance complexity of the equipment.

[0040] As shown in Figures 6 to 8 The positioning frame 21 is provided with a stroke slot 27 on one side, the middle part of the limiting block 24 is rotatably installed with a rotating frame 26, the side away from the limiting block 24 of the rotating frame 26 is provided with a sliding block 28, the sliding block 28 is slidably installed in the inside of the stroke slot 27, one side of the sliding block 28 is provided with a linkage plate 38, the side away from the sliding block 28 of the linkage plate 38 is provided with a linkage rod 29, the linkage rod 29 penetrates through the shunt pipe 16, the inside of the first feeding pipe 17 is rotatably installed with a turnover blocking disc 30, the initial state of the turnover blocking disc 30 is provided in an inclined shape, which can normally discharge, one side of the linkage rod 29 penetrates through the connecting pipe 15, and the bottom of one side of the linkage rod 29 is provided with a connecting rod 31 connected with one side of the turnover blocking disc 30; when the powder enters the first feeding pipe 17 from the connecting pipe 15, the blocking piece 23 in the first feeding pipe 17 is pushed to open the first feeding pipe 17, the sliding rod 22 moves to drive the linkage rod 29 to rise and drive the turnover blocking disc 30 to block the connecting pipe 15;

[0041] The powder from the stirring feed bin 3 enters the first feeding pipe 17 through the connecting pipe 15; the flow pressure of the powder acts on the blocking piece 23 inside the first feeding pipe 17, pushing it to move, thereby opening the passage of the first feeding pipe 17 to allow the material to pass; the movement of the blocking piece 23 drives the sliding rod 22 to displace axially, and the limiting block 24 on the sliding rod 22 moves accordingly; the rotating frame 26 in the middle of the limiting block 24 rotates under the guidance of the sliding block 28 and the stroke groove 27, converting linear motion into rotary motion; the movement of the sliding block 28 is transmitted to the connecting rod 29 through the connecting plate 38, driving the connecting rod 29 to rise; the rising action of the connecting rod 29 drives the turnover blocking disc 30 to rotate through the connecting rod 31 at the bottom of the connecting rod 29, changing from the initial inclined state (allowing discharge) to the vertical state, thereby blocking the feeding passage of the connecting pipe 15 and cutting off the material source; when the powder flow decreases or stops, the flow pressure disappears, and the elastic force of the return spring 25 pushes the sliding rod 22 and all the linkage components (including the rotating frame 26, the sliding block 28, and the connecting rod 29) back to the initial position, and the turnover blocking disc 30 returns to the inclined state, and the connecting pipe 15 passage is reconnected, ready for the next feeding. The whole process is automatically operated, realizes intelligent adjustment based on material flow, automatically limits flow and prevents overload when there is too much material, and automatically resets to keep the passage clear when the material is finished. It not only improves the stability and efficiency of equipment operation, but also eliminates the risk of pollution through mechanical interlocking, ensures production hygiene and quality consistency, and reduces operating costs through low-energy design, suitable for high-speed continuous production scenes.

[0042] In this embodiment, once the material starts to flow, the powder in the stirring feed bin 3 enters the first feeding pipe 17 through the connecting pipe 15, and the fluid pressure generated by the material flow acts on the blocking piece 23. The pressure overcomes the pre-tightening force of the return spring 25, pushing the sliding rod 22 to move axially; the movement of the sliding rod 22 triggers two synchronous actions: a) the blocking piece 23 moves to unblock the first feeding pipe 17, opening the passage to allow the material to flow in; b) through the linkage mechanism, linear motion is converted into rotary motion, driving the connecting rod 29 to rise, and the connecting rod 29 drives the turnover blocking disc 30 to rotate through the connecting rod 31, changing from the inclined state to the vertical state, thereby blocking the inlet of the connecting pipe 15. This pressure driving mechanism immediately breaks the initial state, and the system enters the dynamic working process: the material is smoothly conveyed to the packaging station through the first feeding pipe 17, the shunt pipe 16, and the discharge pipe 20, realizing continuous discharge; and the connecting pipe 15 is blocked to prevent backflow. When the material flow stops, the pressure disappears, and the return spring 25 releases the elastic force to reset all components, reseal the first feeding pipe 17, and open the connecting pipe 15. The whole process is automatically operated, and the initial state is only a static preset, and the state switching is completed instantly during dynamic work. Therefore, there is no contradiction between the structural characteristics of "normal discharge" and the mechanical position of "initial blocking" - the former is a ready function, and the latter is a transient state. The pressure driving ensures seamless connection of the two in time sequence.

[0043] As Figure 4 , Figure 9 , Figure 10 shown, the top of the blanking pipe 20 is provided with a tapered receiving hopper 32 connected with the discharge pipe 19, and the two sides of the blanking pipe 20 are also provided with dust suction pipes 34, which are arranged in U-shaped cross section, and the bottom of the dust suction pipe 34 is provided with a plurality of dust suction slots 35, and the bottom of the blanking pipe 20 is provided with an inclined blanking nozzle 33, and the bottom of the dust suction pipe 34 is clamped in the inclined opening of the inclined blanking nozzle 33;

[0044] The material is discharged from the upstream discharge pipe 19 into the tapered receiving hopper 32; the tapered structure of the tapered receiving hopper 32 guides the material to concentrate and smoothly transition to the inside of the blanking pipe 20, reducing impact and splashing; the material falls in the blanking pipe 20 by gravity, and the dust generated in the process is captured in real time by the U-shaped dust suction pipe 34 (which can be connected to an external dust suction device or negative pressure device) arranged on both sides of the blanking pipe 20 through the dust suction slots 35 at the bottom, which are evenly distributed to ensure that the dust is sucked into the dust removal system at the moment of generation, effectively inhibiting the spread of dust; the material continues to descend to the inclined blanking nozzle 33 at the bottom of the blanking pipe 20, and the inclined opening design optimizes the discharge trajectory, allowing the material to be discharged at a controllable speed and direction into the downstream equipment or packaging container, avoiding blockage or spilling; throughout the process, the dust suction pipe 34 is always tightly clamped to the opening of the inclined blanking nozzle 33, maintaining a sealed state to prevent dust from escaping.

[0045] As Figures 1 to 5 shown, the staggered cleaning assembly includes a wind box 36 fixedly installed on one side of the box body 2, and one side of the wind box 36 is provided with a wind pipe 37 connected with the second feeding pipe 18;

[0046] The compressed air or cleaning liquid in the wind box 36 is injected into the second feeding pipe 18 through the wind pipe 37 under the driving of the pump or air pressure; the cleaning medium enters the interlocking shunt assembly inside along the second feeding pipe 18, and uses high-pressure flushing force to remove residual powder and deposits, especially for key parts such as the sliding rod 22, the blocking piece 23 and the blanking pipe 20; the cleaning process is completely staggered with the production timing to ensure that it does not affect the normal production rhythm.

[0047] In another preferred embodiment, the second feeding pipe 18 can serve as a fault emergency backup channel, which is connected with the main material bin through another independent conveying path; when the main feeding path (the first feeding pipe 17) is interrupted due to powder bin bridging, blockage or mechanical failure, the standby material flows into the shunt pipe 16 through the second feeding pipe 18, and the flow pressure drives the valve core to automatically switch the path, block the fault side inlet and open the standby channel, realizing uninterrupted continuous feeding; this design builds a pure mechanical redundancy system, completely solving the problem of sudden material interruption and shutdown from the hardware level, and significantly improving the reliability and availability of the production line.

[0048] In another preferred embodiment, the second feed pipe 18 can also serve as a formula micro-addition station for injecting high-value additives (such as vitamins, flavors or pharmaceutical active ingredients); the main material enters from the first feed pipe 17 to push the valve core to block the port, when the micro-ingredient needs to be added, the main material flow is temporarily interrupted, the high-pressure additive is injected through the second feed pipe 18 and the valve core is switched, and the additive is accurately sent into the main flow and mixed with the main material for filling; this scheme realizes multi-component pollution-free switching and accurate blending, and is suitable for the production of high-end customized nutritional products and pharmaceutical products.
