Description

An automatic seasoning packaging machine and packaging method Technical Field

[0001] This invention relates to the field of packaging machine technology, specifically to an automatic seasoning packaging machine and packaging method. Background Technology

[0002] Seasonings, especially powdered materials such as pepper powder, chili powder, and five-spice powder, are prone to generating dust during automated packaging and filling processes. Existing automatic seasoning packaging machines mainly focus on achieving basic functions such as bag making, quantitative filling, and heat sealing, and generally lack effective measures to deal with dust residue after filling.

[0003] These dispersed dust particles can cause a series of serious problems: First, a large amount of dust will adhere to the heat-sealing area of ​​the inner wall of the packaging bag (especially the area where the top is about to be sealed), severely contaminating the sealing surface, leading to weak heat sealing and poor airtightness, making it prone to air leakage and bag breakage, directly affecting the product's shelf life and quality control. Second, some fine dust will be drawn back and adhere to the inner wall of the discharge pipe. Long-term accumulation may cause it to become damp and caking, not only clogging the discharge port and affecting the metering accuracy of the next packaging unit, but also potentially contaminating subsequent products, posing a health and safety hazard. Finally, the dust adhering to the bag and pipe walls also causes direct waste of materials and increases production costs.

[0004] Therefore, there is an urgent need for an automatic seasoning packaging machine and packaging method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic seasoning packaging machine and packaging method to solve the problems mentioned in the background art.

[0044] An automatic seasoning packaging method, comprising the above-mentioned automatic seasoning packaging machine, further comprising the following steps:

[0045] S1: Preliminary preparation: The staff pours the seasoning ingredients into the feeding cylinder, and then uses the packaging bag conveying equipment to lay the packaging film roll sleeve on the outside of the discharge pipe. The side of the packaging film roll sleeve abuts against the side heat sealing mechanism.

[0046] S2: Side heat sealing: During the downward movement of the packaging bag, the side heat sealing mechanism is activated to heat seal the sides of the packaging roll film. Both sides are continuously heat-pressed and sealed to form a cylindrical shape.

[0047] S3: End heat sealing: Activate the end heat sealing mechanism to heat seal the bottom end of the tubular packaging film, forming a bottom-sealed packaging bag;

[0048] S4: Material filling: After the seasonings in the feed cylinder are mixed, they are poured into the packaging bag fitted on the discharge pipe through the discharge pipe;

[0049] S5: Cleaning and Dust Removal: The cleaning and dust removal mechanism is activated. Motor 2 drives the piston to reciprocate within the connecting cylinder via the power component, forming an airflow circulation with the connecting component. Dust-laden airflow passes through the rotating cylinder, folded pipe, fixed cylinder, and connecting cylinder into the filter ring cavity to filter the dust. Clean airflow is then transported through the fixed ring cavity, fixed cylinder, and folded pipe to the rotating cylinder, where it is ejected from its through-hole to blow clean the inner wall of the packaging bag. Simultaneously, the deflection component drives the folded pipe to reciprocate as the piston moves, which in turn drives the rotating cylinder to reciprocate, striking the inner wall of the packaging bag to prevent dust adhesion. The striking mechanism periodically strikes the discharge pipe along with the power component, shaking off seasonings that are adhering to the discharge pipe.

[0050] S6: Packaging sealing: The packaging bag continues to move downwards. After a certain distance, the end heat sealing mechanism is activated again to heat seal the top of the packaging bag, realizing automatic continuous packaging of seasonings.

[0051] Compared with the prior art, the beneficial effects of the present invention are:

[0052] Significantly improves sealing quality and product airtightness: By integrating a cleaning and dust removal process after filling and before top sealing, dust adhering to the heat-sealing area on the inner wall of the packaging bag can be effectively removed, ensuring the cleanliness of the heat-sealed surface. This greatly improves the strength and success rate of the top heat seal, fundamentally reducing the risk of air leakage and bag breakage, and extending the product shelf life.

[0053] Achieving efficient and multi-dimensional active cleaning: This invention creatively combines three cleaning methods: airflow blowing, mechanical oscillating impact, and discharge pipe vibration. Circulating airflow continuously blows across the bag wall; the oscillating rotating cylinder expands the cleaning coverage area and gently impacts the bag wall, removing stubborn dust; a synchronized impact mechanism shakes off accumulated dust from the inner wall of the discharge pipe. This synergistic effect of multiple mechanisms ensures comprehensive and thorough cleaning with high efficiency.

[0054] Energy-saving and environmentally friendly while improving material utilization: Adopting a closed-loop airflow design, dust-laden air is filtered by the system's filter cotton, and dust is collected and recyclable, preventing dust spillage and pollution of the working environment, and directly reducing unnecessary material losses. The electrostatic eliminator in the system eliminates static electricity in the airflow, preventing dust from re-adhering due to static electricity and improving the durability of the cleaning effect.

[0055] The structure is ingenious and compact, and the operation is reliable: the cleaning and dust removal mechanism and the striking mechanism share a power source (motor 2). Through ingenious mechanical linkage (eccentric disc, piston, connecting rope, clamping block, etc.), the rotational motion is transformed into multiple actions such as piston suction, tube folding swing and periodic striking. The structure is ingeniously designed, with strong linkage, no need for complex electrical control, stable and reliable operation, and low manufacturing cost.

[0056] High degree of automation and continuity: The equipment realizes full-process automation from film feeding, side sealing, bottom sealing, quantitative filling, inner wall cleaning, tube wall cleaning to top sealing and cutting, which significantly improves the production efficiency, hygiene standards and overall automation level of powder seasoning packaging.

[0067] In this embodiment of the invention, please refer to Figures 1 to 8. An automatic seasoning packaging machine includes a frame 1, a feeding cylinder 2, and a discharging pipe 3. The feeding cylinder 2 is located at the top of the frame 1, and its outlet communicates with the interior of the discharging pipe 3. The discharging pipe 3 is connected to the frame 1. The machine also includes:

[0068] The side heat sealing mechanism 4 is connected to the frame 1 and is located on one side of the discharge pipe 3. It is used to heat seal the side of the packaging bag.

[0070] A cleaning and dust removal mechanism 6, connected to the discharge pipe 3, is used to clean dust that is scattered and adheres to the inner wall of the packaging bag. The cleaning and dust removal mechanism 6 includes: a second motor 61, connected to the side wall of the discharge pipe 3; a connecting cylinder 62, connected to the discharge pipe 3, with a piston 69 slidably abutting inside the connecting cylinder 62; a power component 67, one end connected to the output end of the second motor 61 and the other end connected to the piston 69, used to drive the piston 69 to reciprocate longitudinally; a connecting component 63, one end connected to the bottom of the connecting cylinder 62; a fixed cylinder 64, connected to the other end of the connecting component 63; a folding tube 65, rotatably connected to the fixed cylinder 64 and connected to its interior; a rotating cylinder 66, rotatably connected to the folding tube 65 and connected to its interior, with several sets of through holes on the rotating cylinder 66; and a deflection component 68, one end connected to the piston 69 and the other end connected to the folding tube 65.

[0071] The striking mechanism 7 is connected to the discharge pipe 3 at one end and to the power assembly 67 at the other end, and is used to strike the discharge pipe 3.

[0072] In this embodiment, the feed cylinder 2 is equipped with a drive motor, the output end of which is connected to the agitator. The agitator is located inside the feed cylinder 2. The drive motor drives the agitator to rotate and agitate the raw materials in the feed cylinder 2. The agitator is connected to the conveying auger, which is used to convey the raw materials in the feed cylinder 2 to ensure that the material enters the discharge pipe 3 in a quantitative manner.

[0073] In this embodiment, the frame 1 is connected to the hydraulic cylinder, the hydraulic cylinder is connected to the cutting blade, and the hydraulic cylinder and the cutting blade are located at the bottom of the end heat sealing mechanism 5. The hydraulic cylinder drives the cutting blade to move and cut the sealed packaging bag.

[0074] As one embodiment of the present invention, please refer to Figures 1 to 3. The side heat sealing mechanism 4 includes:

[0075] Motor 41 is connected to frame 1;

[0076] One end of the belt drive component 42 is connected to the output end of the motor 41;

[0077] Gear transmission component 43 is rotatably connected to frame 1, and the other end of gear transmission component 43 is connected to belt transmission component 42.

[0078] The heat sealing wheel 44 is provided in two sets and is connected to the gear transmission component 43.

[0079] The packaging film is guided and conveyed by the packaging bag conveying equipment (not shown in the figure), wraps around the discharge pipe 3 and is conveyed downward. The side heat sealing mechanism 4 is activated. The motor 41 drives the two heat sealing wheels 44 to rotate synchronously relative to each other through the belt drive component 42 and the gear drive component 43. When the packaging film passes between the two heat sealing wheels 44, its two sides are continuously heat-pressed and sealed to form a cylindrical shape.

[0080] As one embodiment of the present invention, please refer to Figures 1 to 3. The end heat sealing mechanism 5 includes:

[0081] The mounting plate 51 is connected to the frame 1;

[0082] Cylinder 52 is connected to the fixed plate 51;

[0083] The sliding plate 53 is connected to the output end of the cylinder 52 and is slidably connected to the fixed plate 51;

[0084] The heat-sealing plate 54 is connected to the sliding plate 53.

[0085] After the tubular film continues to move down to a predetermined length, it pauses. The cylinder 52 in the end heat sealing mechanism 5 is activated, pushing the sliding plate 53 and the heat sealing plate 54 to close, sealing the lower end of the tubular film to form a bottom-sealed packaging bag. Subsequently, the seasoning in the feed cylinder 2 is quantitatively poured into the packaging bag through the discharge pipe 3.

[0086] As one embodiment of the present invention, please refer to Figures 1, 3 to 7, the connecting component 63 includes:

[0087] One-way tube 631, one end of which is connected to the bottom of connecting cylinder 62, and the other end of which is connected to the inside of fixed cylinder 64, and one-way valve 631 is provided on the one-way tube 631;

[0088] A filter ring cavity 632 surrounds the side wall of the connecting cylinder 62 and communicates with its interior. Filter cotton is provided inside the filter ring cavity 632.

[0089] A fixed ring cavity 633 surrounds the side wall of the connecting cylinder 62 and communicates with the interior of the filter ring cavity 632. The filter ring cavity 632 is located inside the fixed ring cavity 633, and an electrostatic eliminator is provided inside the fixed ring cavity 633.

[0090] One-way tube 634 has one end connected to the inside of fixed annular cavity 633 and the other end connected to the inside of fixed cylinder 64. One-way valve 634 is provided on the one-way tube 634.

[0091] The power unit 67 drives the piston 69 to reciprocate at high speed within the connecting cylinder 62;

[0092] When piston 69 moves upward, a negative pressure is generated at the lower part of connecting cylinder 62. This negative pressure is drawn into the dust-laden air in the packaging bag through one-way tube 631 from fixed cylinder 64, folding tube 65, and rotating cylinder 66.

[0093] When piston 69 moves downward, the one-way valve of one-way tube 631 closes, forcing the air in connecting cylinder 62 through filter ring cavity 632, fixed ring cavity 633, one-way tube 634, fixed cylinder 64, and folded tube 65 into rotating cylinder 66. Filter ring cavity 632 filters dust in the air, and static eliminator eliminates static electricity in the clean air. This dry, static-free clean airflow is guided by folded tube 65 and finally ejected at high speed from each through hole of rotating cylinder 66, blowing directly onto the inner wall of the packaging bag.

[0094] As one embodiment of the present invention, please refer to Figures 1, 3 to 7, the power assembly 67 includes:

[0095] Rotating disk 671 is connected to the output terminal of motor 61;

[0096] The fixed rod 672 is connected to the eccentric part of the rotating disk 671;

[0097] The slot plate 673 is movably engaged with the fixing rod 672;

[0098] The sliding rod 674 is connected to the slot plate 673 at its top end and to the piston 69 at its bottom end. The sliding rod 674 is slidably connected to the connecting cylinder 62.

[0099] Motor 61 drives the rotating disk 671 to rotate, and drives the piston 69 to reciprocate at high speed in the connecting cylinder 62 through the fixed rod 672, the slot plate 673 and the sliding rod 674.

[0100] As one embodiment of the present invention, please refer to Figures 5, 6 and 8, the deflection component 68 includes:

[0101] A connecting rope 681 is connected at one end to a piston 69 and at the other end to a folding tube 65. The connecting rope 681 is wound around the folding tube 65.

[0102] The spiral spring 682 is connected at one end to the folded tube 65 and at the other end to the fixed cylinder 64.

[0103] When the piston 69 moves upward, it pulls the folding tube 65 through the connecting rope 681, causing it to overcome the torque of the spiral spring 682 and deflect in one direction. When the piston 69 moves downward, the connecting rope 681 is released, and the spiral spring 682 drives the folding tube 65 to swing back. This process repeats, causing the rotating cylinder 66 to not only spray air, but also swing back and forth within a certain angle and gently tap the bag wall, causing the firmly adhered dust to fall off.

[0104] As one embodiment of the present invention, please refer to Figures 1, 3 to 5, and 7. The striking mechanism 7 includes:

[0105] Card block 71 is connected to card slot plate 673;

[0106] The telescopic rod 72 is connected at one end to the discharge pipe 3;

[0107] Connecting plate 73 is connected to the other end of telescopic rod 72;

[0108] Spring 74 is connected at one end to connecting plate 73 and at the other end to discharge pipe 3;

[0109] The striking block 75 is connected to the connecting plate 73;

[0110] The locking teeth 76 are connected to the connecting plate 73.

[0111] The striking mechanism 7 works synchronously: the locking block 71 fixed on the locking plate 673 moves longitudinally back and forth with it. When the locking plate 673 moves to abut against the locking tooth 76, the locking block 71 squeezes the locking tooth 76 on the connecting plate 73, causing the connecting plate 73 and the striking block 75 to overcome the elastic force of the spring 74 and store energy. Then the locking block 71 disengages from the locking tooth 76, the spring 74 is released, and the striking block 75 is driven to strike the outer wall of the discharge pipe 3. The resulting vibration causes the dust adhering to the inner wall of the discharge pipe 3 to fall off and fall into the packaging bag being cleaned below and be removed together. At the same time, it prevents the powder from adhering to the inner wall of the discharge pipe 3 and not falling off.

[0112] In this embodiment, the striking block 75 is made of flexible materials such as polyurethane, nylon or rubber, which can generate effective impact without damaging the discharge pipe 3.

[0113] As one embodiment of the present invention, please refer to Figures 1, 3 and 4, it also includes:

[0114] The limiting roller 8 is connected to the discharge pipe 3.

[0115] The packaging film is guided and stretched by the set limit roller 8.

[0116] An automatic seasoning packaging method, comprising the above-mentioned automatic seasoning packaging machine, further comprising the following steps:

[0117] S1: Preliminary preparation: The staff pours the seasoning ingredients into the feeding cylinder 2, and then uses the packaging bag conveying equipment to lay the packaging film roll sleeve on the outside of the discharge pipe 3. The side of the packaging film roll sleeve abuts against the side heat sealing mechanism 4.

[0118] S2: Side heat sealing: During the downward movement of the packaging bag, the side heat sealing mechanism 4 is activated to heat seal the side of the packaging roll film. Both sides are continuously heat-pressed and sealed to form a cylindrical shape.

[0119] S3: End heat sealing: Activate the end heat sealing mechanism 5 to heat seal the bottom end of the tubular packaging film to form a bottom-sealed packaging bag;

[0120] S4: Material filling: After the seasoning in the feed cylinder 2 is mixed, it is poured into the packaging bag sleeved on the discharge pipe 3 through the discharge pipe 3;

[0121] S5: Cleaning and dust removal: The cleaning and dust removal mechanism 6 is activated. Motor 61 drives piston 69 to reciprocate within connecting cylinder 62 via power component 67, forming an airflow circulation with the connecting component 63. The dust-laden airflow enters the filter ring cavity 632 through rotating cylinder 66, folded pipe 65, fixed cylinder 64, and connecting cylinder 62 to filter the dust. The clean airflow is then delivered to rotating cylinder 66 through fixed ring cavity 633, fixed cylinder 64, and folded pipe 65, and sprayed out from its through hole to blow the inner wall of the packaging bag. At the same time, deflection component 68 drives folded pipe 65 to reciprocate as piston 69 moves, which in turn drives rotating cylinder 66 to reciprocate, striking the inner wall of the packaging bag to prevent dust adhesion. The striking mechanism 7 periodically strikes discharge pipe 3 with the movement of power component 67, shaking off seasonings that are adhering to the discharge pipe 3.

[0122] S6: Packaging sealing: The packaging bag continues to move downwards. After a certain distance, the end heat sealing mechanism 5 is activated again to heat seal the top of the packaging bag, realizing automatic continuous packaging of seasonings.

[0123] The working principle of this invention is as follows: the packaging film roll is guided and conveyed by the packaging bag conveying equipment (not shown in the figure), wraps around the discharge pipe 3 and is conveyed downward. The side heat sealing mechanism 4 is activated: the motor 41 drives the two heat sealing wheels 44 to rotate synchronously relative to each other through the belt drive component 42 and the gear drive component 43. When the packaging film passes between the two heat sealing wheels 44, its two sides are continuously heat-pressed and sealed to form a cylindrical shape.

[0124] After the tubular film continues to move down to a predetermined length, it pauses. The cylinder 52 in the end heat sealing mechanism 5 is activated, pushing the sliding plate 53 and the heat sealing plate 54 to close, sealing the lower end of the tubular film to form a bottom-sealed packaging bag. Subsequently, the seasoning in the feed cylinder 2 is quantitatively poured into the packaging bag through the discharge pipe 3.

[0125] After the material is discharged, the cylindrical membrane continues to move downwards by one end. During this process, motor 61 drives the rotating disk 671 to rotate, which in turn drives the piston 69 to reciprocate at high speed inside the connecting cylinder 62 through the fixed rod 672, the slot plate 673, and the sliding rod 674.

[0126] When piston 69 moves upward, a negative pressure is generated at the lower part of connecting cylinder 62. This negative pressure is drawn into the dust-laden air in the packaging bag through one-way tube 631 from fixed cylinder 64, folding tube 65, and rotating cylinder 66.

[0127] When piston 69 moves downward, the one-way valve of one-way tube 631 closes, forcing the air in connecting cylinder 62 through filter ring cavity 632, fixed ring cavity 633, one-way tube 634, fixed cylinder 64, and folded tube 65 into rotating cylinder 66. Filter ring cavity 632 filters dust in the air, and static eliminator removes static electricity from the clean air. This dry, static-free clean airflow is guided by folded tube 65 and finally sprayed out at high speed from each through hole of rotating cylinder 66, directly blowing towards the inner wall of the packaging bag to clean the inner wall of the packaging bag.

[0128] At the same time, when the piston 69 moves upward, it pulls the folding tube 65 through the connecting rope 681, causing it to overcome the torque of the spiral spring 682 and deflect in one direction; when the piston 69 moves downward, the connecting rope 681 is released, and the spiral spring 682 drives the folding tube 65 to swing back. This process is repeated, so that the rotating cylinder 66 not only sprays air, but also swings back and forth within a certain angle and gently taps the bag wall, causing the firmly adhered dust to fall off.

[0129] The striking mechanism 7 works synchronously: the locking block 71 fixed on the locking plate 673 moves longitudinally back and forth with it. When the locking plate 673 moves to abut against the locking tooth 76, the locking block 71 squeezes the locking tooth 76 on the connecting plate 73, which drives the connecting plate 73 and the striking block 75 to overcome the elastic force of the spring 74 and store energy. Then the locking block 71 disengages from the locking tooth 76, the spring 74 is released, and the striking block 75 is driven to strike the outer wall of the discharge pipe 3. The resulting vibration causes the dust adhering to the inner wall of the discharge pipe 3 to fall off and fall into the packaging bag being cleaned below and be removed together. At the same time, it prevents the powder from adhering to the inner wall of the discharge pipe 3 and not falling off.

[0130] The packaging bag continues to move downwards, and after a certain distance, the end heat sealing mechanism 5 is activated again to heat seal the top of the packaging bag, thus realizing automatic continuous packaging of the seasoning.
