Description

A fully automatic powder packaging equipment with low residual oxygen content Technical Field

[0001] This invention relates to the field of packaging equipment, and more particularly to a fully automatic powder packaging equipment with low residual oxygen content. Background Technology

[0002] In the packaging of high-end powder materials such as food, pharmaceuticals, milk powder, health products, fine chemicals, and metal powders, long-term preservation, moisture protection, oxidation prevention, and maintenance of the stability of active ingredients are crucial quality requirements. Among these, the residual oxygen level within the packaging container is one of the core indicators for measuring packaging quality. Excessive residual oxygen can directly lead to oxidation and deterioration of powder materials, loss of nutrients, flavor degradation, microbial growth, and even safety hazards, severely shortening product shelf life and affecting safety during use.

[0003] Most ordinary automatic filling and packaging machines only perform the basic functions of metering and bagging. They usually rely solely on the natural displacement of air inside the bag by the falling powder, or simply evacuate the air after filling. This method results in extremely high residual oxygen levels (often exceeding 5%-10%), which are highly unstable and cannot meet the packaging requirements for food preservation, pharmaceutical activity, and easily oxidized metal powders. Some equipment attempts to integrate nitrogen filling functions, but these are mostly simple "nitrogen injection after filling." The nitrogen flow, the falling powder, and the airflow inside the bag lack coordinated design, resulting in low replacement efficiency, numerous dead zones, and difficulty in achieving the goal of stable and extremely low residual oxygen levels. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic powder packaging equipment with low residual oxygen content, which can realize the automated bagging, filling, degassing and nitrogen filling of powder materials.

[0027] Example:

[0028] As shown in Figures 1-9, the present invention proposes a fully automatic powder packaging equipment with low residual oxygen content, comprising a main frame and a bag feeder 1. The main frame is sequentially equipped with a main filling mechanism 2, an air extraction mechanism 3, a secondary filling machine 4, a bag support and edge pressing mechanism 5, and a heat sealing machine 6. A main conveyor line 7 and a weighing belt conveyor 8 are fixedly connected to the main frame. The main conveyor line 7 is divided into two sections, which are respectively connected end-to-end to the two ends of the weighing belt conveyor 8. The main filling mechanism 2 includes a first lifting device 201 and a Y-shaped material box 202 fixed to the main frame, a screw feeder 203 and a main air filling pipe 208 fixedly connected to the Y-shaped material box 202, an O-shaped frame 204 fixed to the moving platform of the first lifting device 201, a bag clamping cylinder 205 and an air extraction pipe 206 fixed to the O-shaped frame 204, and a bag clamping plate 207 fixedly connected to the piston rod of the bag clamping cylinder 205. The main conveyor line 7 is located at the air extraction mechanism... A vibration assembly is installed below the bag-supporting and edge-pressing mechanism 5. The bag-supporting and edge-pressing mechanism 5 includes a mounting base 501, a third lifting device 502, a bag-supporting lifting seat 503, a second rotating device 504, a bag-supporting arm 505, a vacuum flat tube 506, an XY moving module 507, a roller 508, a linear module 509, an edge-pressing cylinder 510, and a bag mouth clamp 511. An auxiliary inflation pipe 512 is fixedly connected to the bag-supporting arm 505, and a Y-shaped material box 202. The feed end is fixedly connected to an annular air inflator, which consists of multiple annular tubes 901 and connecting tubes 902 located between adjacent annular tubes 901. The auxiliary air inflator 512, the annular tubes 901 and the connecting tubes 902 are all provided with air inflator holes. The air extraction mechanism 3 includes a second lifting device 301 fixed on the main frame, a degassing tube 302 fixed on the moving platform of the second lifting device 301, and a degassing filter element 303 fixed at the lower end of the degassing tube 302.

[0029] The packaging bag feeding machine 1 includes a feeding conveyor line 101, a feeding robot 102, a bag-supporting mechanism 103, and a feeding machine frame 104. The feeding conveyor line 101 feeds stacked packaging bags, and the bag-supporting mechanism 103 and the feeding robot 102 support and feed the packaging bags.

[0030] The Y-shaped feeder 202 consists of a vertical section and an inclined section. The inclined section is the feed end of the Y-shaped feeder 202, and the vertical section is the discharge end of the Y-shaped feeder 202. After the material is put into the Y-shaped feeder 202, the powder is fed by the screw feeder 203. During the filling process, nitrogen is injected into the bagged material through the main air filling pipe 208. A first rotating device 209 is fixedly connected to the side wall of the main air filling pipe 208. The first rotating device 209 drives the flip cover 210 to open and close.

[0031] The degassing filter element 303 is specifically a polytetrafluoroethylene filter element. After the bagged material is inserted, the degassing filter element 303 can block the powder material, and the micropores on the degassing filter element 303 can allow gas to pass through for extraction.

[0032] When the bagged material is being squeezed and pressed at the bag-supporting and pressing mechanism 5, the bagged material is conveyed to the material-blocking cylinder 704 via the main conveyor line 7 and stops. The third lifting device 502 drives the bag-supporting lifting seat 503 to descend, and the bag-supporting arm 505 and the vacuum tube 506 are inserted into the bag opening. Then, the second rotating device 504 drives the bag-supporting arm 505 to open the bag opening into a flat shape, moving it away from the vacuum tube 506. Subsequently, the piston rod of the pressing cylinder 510 extends, and the bag opening clamp 511 presses the bag opening tightly. After that, X... The Y-moving module 507 drives the roller 508 to roll downwards from both sides of the bag opening to expel excess air. During this process, on the one hand, the vacuum tube 506 simultaneously removes excess air from the bag opening, and on the other hand, the vibrating hammer 11 causes the support platform 10 to vibrate, shaking and loosening the powder to remove the air remaining between the powder particles, further removing residual oxygen from the bagged material. Afterwards, the XY moving module 507 drives the roller 508 to reset, and the third lifting device 502 drives the bag support arm 505 and the vacuum tube 506 to be pulled out from the bag opening of the bagged material.

[0033] A bag mouth guide plate 601 is arranged parallel to the feed end of the heat sealing machine 6. The bag mouth guide plate 601 is used to limit the material flow of the closed bag mouth.

[0034] The vibration assembly includes a support platform 10, a vibrating hammer 11, a spring 12, and a crossbeam 13. The support platform 10 is located inside the conveyor belt of the main conveyor line 7. The crossbeam 13 is fixedly connected to the frame of the main conveyor line 7. The spring 12 is located between the support platform 10 and the crossbeam 13. The vibrating hammer 11 is fixedly connected to the support platform 10.

[0035] A transverse moving mechanism 701 is fixedly connected to the main conveyor line 7 below the main filling mechanism 2 and the air extraction mechanism 3. A clamping cylinder 702 is fixedly connected to the moving platform of the transverse moving mechanism 701. A bag clamping plate 703 is fixedly connected to the piston rod of the clamping cylinder 702. A material blocking cylinder 704 is fixedly connected to the main conveyor line 7 below the bag supporting and pressing mechanism 5.

[0036] Both the main conveyor line 7 and the weighing belt conveyor 8 are fixedly connected to the frame of the feeding guide plate 14, which can limit and guide the conveying of bagged materials.

[0037] The packaging process of this invention is as follows:

[0038] Step 1: Opening and feeding the packaging bags; the stack of packaging bags is manually placed on the feeding conveyor line 101 and transported to the picking station. The first lifting device 201 drives the O-shaped frame 204 to descend. Then, the feeding robot 102 drives the bag-opening mechanism 103 to open the packaging bags and feed them between the O-shaped frame 204 and the bag clamping plate 207. The piston rod of the bag clamping cylinder 205 extends and drives the bag clamping plate 207 to press the packaging bags tightly onto the O-shaped frame 204. After that, the feeding robot 102 and the bag-opening mechanism 103 are reset. The first lifting device 201 drives the O-shaped frame 204 and the packaging bags to rise to the filling station, so that the discharge end of the Y-shaped material box 202 is located at the bottom of the bag.

[0039] Step 2: Filling the powder material. A large amount of nitrogen gas is introduced into the Y-shaped material box 202 through the annular air inflator. Then, the powder material is added into the Y-shaped material box 202. During the material feeding process, the air in the powder material is replaced, reducing the residual oxygen content. The powder material is conveyed by the screw feeder 203. After the first rotating device 209 drives the flip cover 210 to rotate and open, the powder material will fall into the packaging bag for filling. During this process, nitrogen gas is introduced into the packaging bag through the main air inflator 208. The dust generated during the filling process is removed through the air extraction pipe 206. After the filling action is completed, the first lifting device 201 drives the O-shaped frame 204 to descend, and the packaging bag is placed on the main conveyor line 7. The piston rod of the bag clamping cylinder 205 retracts, and the bag clamping plate 207 loosens.

[0040] Step 3: Degassing of the powder material inside the bag. After filling and lowering, the bagged material is first clamped and positioned by the clamping cylinder 702 driving the bag clamping plate 703. Driven by the lateral moving mechanism 701, the bagged material is conveyed to the degassing station along the main conveyor line 7. Then, the second lifting device 301 drives the degassing pipe 302 and the degassing filter element 303 to descend and insert into the powder of the bagged material. Air is extracted through the degassing pipe 302 and the degassing filter element 303. The degassing filter element 303 has a microporous structure, which can block the powder material and remove gas. During the extraction process, the powder inside the bagged material is shaken by the vibration component to further remove air and reduce residual oxygen. After the degassing and shaking treatment is completed, the second lifting device 301 drives the degassing pipe 302 and the degassing filter element 303 to reset, and the clamping cylinder 702 drives the bag clamping plate 703 to loosen.

[0041] Step 4: Weighing and replenishing the bagged materials. The bagged materials are conveyed to the weighing belt conveyor 8 via the main conveyor line 7 for weighing. If the weight of the bagged materials is insufficient, they are replenished by the auxiliary filling machine 4. The bagged materials that meet the weight standard are conveyed to the main conveyor line 7 for the next step.

[0042] Step 5: Perform edge-supporting and compression treatment on the bagged material. The bagged material is conveyed to the stop cylinder 704 via the main conveyor line 7. The bag-supporting lifting seat 503 is lowered by the third lifting device 502. The bag-supporting arm 505 and the vacuum flat tube 506 are inserted into the bag opening. Then, the bag-supporting arm 505 is driven by the second rotating device 504 to open the bag opening into a flat shape away from the vacuum flat tube 506. Subsequently, the piston rod of the edge-pressing cylinder 510 extends, and the bag opening clamp 511 presses the bag opening tightly. Then, the XY moving module 507 drives the roller 508 to roll downward from both sides of the bag opening to expel excess air. During this process, on the one hand, the vacuum flat tube 506 simultaneously removes excess air from the bag opening, and on the other hand, the vibrating hammer 11 causes the support table 10 to generate... Vibration and shaking loose powder remove air trapped between powder particles, further reducing residual oxygen in the bagged material. Then, the XY moving module 507 drives the roller 508 to reset, and the third lifting device 502 drives the bag support arm 505 and the vacuum tube 506 to be pulled out from the bag opening of the bagged material. After that, the blocking end of the blocking cylinder 704 moves away to make way, and the main conveyor line 7 continues to convey the bagged material. During this process, the bag opening clamp 511 is still in a state of pressing the bag opening. The linear module 509 drives the edge pressing cylinder 510 and the bag opening clamp 511 to cooperate with the main conveyor line 7 for follow-up conveying. After the linear module 509 drives the edge pressing cylinder 510 to move to the final position, the piston rod of the edge pressing cylinder 510 retracts, realizing the exhaust of the bagged material and the flat closing of the bag opening into the bag opening guide plate 601.

[0043] Step 6: After being squeezed by the support, the bag opening of the bagged material is conveyed and discharged through the main conveyor line 7 under the limit of the bag opening guide plate 601. During the discharge process, the bag opening of the bagged material is heat-sealed by the heat sealing machine 6.
