Description

Technical Field

[0001] This utility model relates to the field of nitrogen-filled powder bagging technology, specifically to a powder bagging feeding device with nitrogen-filling function. Background Technology

[0002] Nitrogen-filled powder packaging technology is now widely used in food, pharmaceutical, and chemical industries. Its core requirement is to achieve the functions of preservation, anti-oxidation, and antibacterial properties of powder materials by filling them with nitrogen.

[0003] Currently, when filling powder bags with nitrogen, an external nitrogen filling device is used. The outer casing of the nitrogen filling device is fixedly installed on the frame of the packaging machine, and nitrogen gas is injected into the powder bag through the nitrogen filling nozzle. However, when using an external nitrogen filling device to fill powder bags, if the powder bag is already filled with powder, the instant the nitrogen gas enters and comes into direct contact with the powder can cause powder splashing. If the powder and nitrogen are filled simultaneously, the nitrogen filling direction of the external nitrogen filling device will inevitably form an angle with the powder filling direction, and there is still a risk of powder splashing. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a powder bag feeding device with nitrogen filling function, which aims to solve the problem that powder splashing occurs when using an external nitrogen filling device to fill the powder bag with nitrogen.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a powder bag feeding device with nitrogen filling function, the powder bag feeding device including a filling mechanism, a collecting mechanism disposed on the filling mechanism, and a bag body mechanism disposed at one end of the filling mechanism;

[0006] The filling mechanism includes a nitrogen filling component and a discharge pipe disposed inside the nitrogen filling component, wherein the nitrogen filling component and the discharge pipe are arranged in parallel.

[0007] The nitrogen filling component and the feeding pipe are sealed at the ends away from the bag body mechanism, and open at the ends near the bag body mechanism. The openings of the nitrogen filling component and the feeding pipe are aligned with the bag body mechanism, and nitrogen and powder enter the bag body mechanism simultaneously.

[0008] According to one aspect of the above technical solution, the nitrogen filling assembly includes a nitrogen pipe arranged parallel to the feed pipe, a flow meter and a flow valve disposed on the nitrogen pipe, and a nitrogen filling space for nitrogen flow is provided between the nitrogen pipe and the feed pipe.

[0009] According to one aspect of the above technical solution, the flow meter and the flow valve are connected to the nitrogen filling space.

[0010] According to one aspect of the above technical solution, the end of the feeding pipe away from the bag body mechanism is funnel-shaped, and it is sealed to the inner circumference of the end of the nitrogen pipe away from the bag body mechanism.

[0011] According to one aspect of the above technical solution, the collection mechanism includes a first collection box and a second collection box sleeved outside the nitrogen pipe, and an adsorption tube provided on the first collection box, wherein the adsorption holes on the adsorption tube are arranged facing the bag body mechanism.

[0012] According to one aspect of the above technical solution, the adsorption pores are evenly spaced on the adsorption tube.

[0013] According to one aspect of the above technical solution, the first receiving box includes a curved part sleeved on the nitrogen tube and a collecting part arranged perpendicular to the nitrogen tube. The curved part is provided with a round hole, which is aligned with the bag body mechanism.

[0014] According to one aspect of the above technical solution, the diameter of the circular hole is larger than the diameter of the nitrogen tube.

[0015] According to one aspect of the above technical solution, the second receiving box is arranged parallel to the collecting part, and the second receiving box is provided with a through groove, which is in the shape of an inverted funnel.

[0016] According to one aspect of the above technical solution, the bag body mechanism includes a bag maker located below the nitrogen pipe and a bag film located on the bag maker, the bag film being bent toward the nitrogen pipe.

[0017] In summary, the powder bag filling device with nitrogen filling function provided by this utility model reduces the angle between the nitrogen filling direction and the powder filling direction by arranging the nitrogen pipe and the filling pipe in parallel, thereby reducing the degree of splashing when nitrogen and powder come into contact. Simultaneously, the nitrogen pipe is wrapped around the filling pipe, the nitrogen nozzle is aligned with the filling direction, and the flow rate is uniform, reducing powder splashing caused by direct airflow impacting the powder. By installing a flow meter and flow valve on the nitrogen pipe, the flow rate and volume of nitrogen can be controlled according to the properties of the filling material and the filling speed, ensuring a continuous flow of nitrogen into the packaging bag, preventing air from entering, thus reducing the force of nitrogen filling and further reducing powder splashing. Furthermore, by setting a first collection box and a second collection box on the bag body, splashed powder can be collected to avoid waste. The bag film, bent towards the nitrogen pipe, also prevents powder from adhering to the outside of the bag film, eliminating the need for external cleaning of the powder bag formed by the bag film and improving production capacity.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0029] Please see Figures 1-5 The diagram shows a schematic representation of a powder bagging and discharging device with nitrogen filling function according to an embodiment of the present invention. The powder bagging and discharging device includes a filling mechanism 100, a collecting mechanism 200 disposed on the filling mechanism 100, and a bag body mechanism 300 disposed at one end of the filling mechanism 100, wherein:

[0030] In the prior art, to avoid the impact of the injected nitrogen gas on the powder and causing splashing, the nitrogen nozzle is often tilted at an angle (e.g., 45°) to the bag filling direction to reduce direct impact on the powder. However, this design may still cause powder to splash onto the inner wall and outer surface of the bag. To avoid this phenomenon, the filling mechanism 100 proposed in this embodiment includes a nitrogen filling component 110 and a discharge pipe 120 disposed inside the nitrogen filling component 110. The nitrogen filling component 110 and the discharge pipe 120 are arranged in parallel. The ends of the nitrogen filling component 110 and the discharge pipe 120 away from the bag body mechanism 300 are sealed, while the ends of the nitrogen filling component 110 and the discharge pipe 120 close to the bag body mechanism 300 are open. The openings of the nitrogen filling component 110 and the discharge pipe 120 are aligned with the bag body mechanism 300, and nitrogen gas and powder enter the bag body mechanism 300 simultaneously.

[0031] Furthermore, the nitrogen filling assembly 110 includes a nitrogen pipe 111 arranged parallel to the feed pipe 120, a flow meter 112 and a flow valve 113 disposed on the nitrogen pipe 111, and a nitrogen filling space for nitrogen flow between the nitrogen pipe 111 and the feed pipe 120. The flow meter 112 and the flow valve 113 are connected to the nitrogen filling space. The end of the feed pipe 120 away from the bag body mechanism 300 is funnel-shaped and sealed to the inner circumference of the end of the nitrogen pipe 111 away from the bag body mechanism 300. By sealing one end of the feed pipe 120 and the nitrogen pipe 111, nitrogen and powder are controlled to enter the bag body mechanism 300 in a parallel direction, reducing the angle between nitrogen and powder and reducing the degree of splashing when nitrogen and powder come into contact.

[0032] Meanwhile, to reduce the impact of residual oxygen, carbon dioxide, and other gases inside the packaging bag on product quality, this device employs continuous nitrogen filling. Based on the properties of the filling material and the filling speed, the flow rate and velocity of nitrogen are adjusted via flow valve 113 and flow meter 112, ensuring a continuous flow of nitrogen into the packaging bag and preventing air from entering. The nitrogen pipe 111 is wrapped around the filling pipe, and the nitrogen nozzle is aligned with the filling direction with a uniform flow rate, reducing powder splashing caused by direct airflow impact. During the bottom sealing of the bag, the temperature reaches as high as 120℃; controlled nitrogen pressure prevents damage or deformation of the seal due to excessive nitrogen pressure.

[0033] Furthermore, the collection mechanism 200 includes a first collection box 210 and a second collection box 230 fitted around the nitrogen tube 111, and an adsorption tube 220 on the first collection box 210. Adsorption holes 221 on the adsorption tube 220 face the bag body mechanism 300 and are evenly spaced on the adsorption tube 220. The first collection box 210 includes a curved section 211 fitted around the nitrogen tube 111 and a collection section 213 perpendicular to the nitrogen tube 111. The curved section 211 has a circular hole 212 aligned with the bag body mechanism 300. The diameter of the circular hole 212 is larger than the diameter of the nitrogen tube 111. The second collection box 230 is parallel to the collection section 213 and has a passage groove 231 in the shape of an inverted funnel.

[0034] It should be noted that when nitrogen comes into contact with the powder, a small amount of powder will splash out from the bag mechanism 300. Therefore, a first receiving box 210 is provided at the inlet of the bag mechanism 300, and an adsorption tube 220 is equipped on the first receiving box 210. When the powder splashes out from the bag mechanism 300, it is adsorbed by the adsorption tube 220 located at the connection between the curved part 211 and the collecting part 213. The adsorption holes 221 on the adsorption tube 220 are aligned with the inlet of the bag mechanism 300 to adsorb the splashed powder into the adsorption tube 220.

[0035] Because the curved surface 211 is bent and has a circular hole 212 with a diameter larger than that of the nitrogen pipe 111, the upward-splashing powder enters the collection section 213 through the gap between the circular hole 212 and the nitrogen pipe 111. Furthermore, the second collection box has an inverted funnel-shaped channel 231, which is wider at the bottom and narrower at the top. Powder continuing upwards passes through the channel 231 into the second receiving box 230 to collect the splashed powder. Through the collection functions of the first receiving box 210, the adsorption tube 220, and the second receiving box 230, powder waste is avoided.

[0036] The bag-making mechanism includes a bag-making device 310 located below the nitrogen pipe 111 and a bag film 320 disposed on the bag-making device 310, the bag film 320 being bent toward the nitrogen pipe 111. Because the bag film 320 is bent toward the nitrogen pipe 111, the injected powder adheres to the inside of the powder bag formed by the bag film 320, preventing powder from adhering to the outside of the bag film 320. This eliminates the need for external cleaning of the powder bag formed by the bag film 320, thus improving production capacity.

[0037] In summary, the powder bag filling device with nitrogen filling function provided by this utility model reduces the angle between the nitrogen filling direction and the powder filling direction by arranging the nitrogen pipe and the filling pipe in parallel, thereby reducing the degree of splashing when nitrogen and powder come into contact. Simultaneously, the nitrogen pipe is wrapped around the filling pipe, the nitrogen nozzle is aligned with the filling direction, and the flow rate is uniform, reducing powder splashing caused by direct airflow impacting the powder. By installing a flow meter and flow valve on the nitrogen pipe, the flow rate and volume of nitrogen can be controlled according to the properties of the filling material and the filling speed, ensuring a continuous flow of nitrogen into the packaging bag, preventing air from entering, thus reducing the force of nitrogen filling and further reducing powder splashing. Furthermore, by setting a first collection box and a second collection box on the bag body, splashed powder can be collected to avoid waste. The bag film, bent towards the nitrogen pipe, also prevents powder from adhering to the outside of the bag film, eliminating the need for external cleaning of the powder bag formed by the bag film and improving production capacity.
