Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to an air extraction and bag mouth cleaning device and a bag-feeding packaging machine equipped with it. Background Technology

[0002] In the packaging process of powdered materials, a key step is the automatic filling of the powder into pre-made packaging bags. Due to the characteristic that powdered materials fall into the bags automatically in a free state, a large amount of air often remains inside the bags. This air residue phenomenon is particularly significant in the packaging process of powdered materials because the gaps between powder particles are large, making it easy for air to get trapped.

[0003] Excessive air inside the bag directly affects the sealing quality. When the air content inside the packaging bag is too high, the seal may not be tight due to uneven air pressure. This can lead to air leakage during subsequent storage and transportation, thus affecting the product's shelf life and safety.

[0004] Furthermore, excessive air inside the bag can reduce palletizing efficiency and safety. On automated packaging lines, bags filled with materials need to be neatly stacked for transportation and storage. If the bags contain a large amount of air, their shape and volume become unstable, increasing the difficulty of palletizing and potentially causing them to collapse during the process, leading to safety accidents and impacting logistics efficiency.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of the present invention are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0025] When powdered materials (such as flour, starch, and fried chicken powder) fall freely into the packaging bag, they often result in excessive air inside the bag, which in turn affects sealing quality, palletizing efficiency, safety, and the smoothness of logistics and transportation. To solve this problem, this application designs a special device suitable for bag packaging machines, installed after the filling station and before the sealing station.

Figure 2 This is a schematic diagram of the structure of one embodiment of the extraction pipe of this application. Figure 3 for Figure 2 A cross-sectional view of the embodiment shown. Figure 4 for Figure 1 The diagram shown in the embodiment illustrates the structure of the bag opening cleaning component. Figure 5 This is a top view of one embodiment of the fixing component of this application.

[0027] Combination Figures 1 to 5It is understood that the air extraction and bag opening cleaning device may include an air extraction assembly and a bag opening cleaning assembly. Specifically, the air extraction assembly may include a propulsion cylinder 3, a propulsion cylinder piston rod 6, an air extraction nozzle 7, a connecting piece 8, an air extraction pipe, and a vacuum pump. One end of the propulsion cylinder piston rod 6 is connected to the propulsion cylinder 3, and the other end is fixedly connected to the connecting piece 8. The air extraction nozzle 7 is installed on the connecting piece 8 and connected to the vacuum pump. The air extraction pipe is connected to the connecting piece 8. The propulsion cylinder 3 is used to control the displacement of the propulsion cylinder piston rod 6. Furthermore, the air extraction assembly may also include a contact sensor 4, which is disposed on the propulsion cylinder 3 and used to monitor the displacement of the propulsion cylinder piston rod 6. The air extraction pipe is connected to the propulsion cylinder piston rod 6 through the hollow stainless steel connecting piece 8 and the nut 25.

[0028] The vacuuming assembly controls the displacement of the piston rod 6 of the propulsion cylinder 3, which in turn drives the vacuum nozzle 7 to extend into the packaging bag, connecting with a vacuum pump to achieve the vacuuming function. The bag opening cleaning assembly receives compressed air through the bag opening cleaning nozzle 10 and outputs compressed air through the air outlet 11 of the bag opening cleaning component for cleaning the bag opening. This structure achieves integrated operation of vacuuming and bag opening cleaning, improving packaging efficiency and sealing quality, while avoiding sealing defects caused by material residue at the bag opening. In addition, the contact sensor 4 is used to monitor the displacement of the piston rod 6 of the propulsion cylinder, thereby achieving precise control of the vacuuming depth. The addition of the contact sensor 4 makes the vacuuming process more intelligent, allowing for adaptive adjustments based on different materials and the depth of the packaging bag, improving the accuracy and efficiency of vacuuming.

[0029] The suction assembly may further include a first propulsion nozzle 1 and a second propulsion nozzle 5, which are respectively disposed at both ends of the propulsion cylinder 3. The suction pipe includes a hollow titanium tube 13 and a pointed titanium tube with a micron-sized filter 14. The hollow titanium tube 13 is connected to a connector 8. The pointed titanium tube with a micron-sized filter 14 includes a pointed titanium tube 14-1, an air hole 14-2, and a micron-sized titanium filter 14-3. The air hole 14-2 is formed in the pointed titanium tube 14-1, and the micron-sized titanium filter 14-3 covers the outer surface of the pointed titanium tube 14-1. The structure of the suction assembly is further refined here, including the first propulsion nozzle 1, the second propulsion nozzle 5, and the suction pipe composed of the hollow titanium tube 13 and the pointed titanium tube with a micron-sized filter 14. The design of the pointed titanium tube with a micron-sized filter 14 ensures both suction efficiency and prevents material blockage. This structural design not only improves the stability and reliability of air extraction, but also effectively filters impurities in the air through the micron-sized titanium gold filter 14-3, ensuring the cleanliness of the air extraction process.

[0030] The bag opening cleaning assembly may include a bag opening cleaning component 9, a bag opening cleaning nozzle 10, and a bag opening cleaning component air outlet 11. The bag opening cleaning component 9 is installed on the outer wall of the suction pipe, and the bag opening cleaning nozzle 10 and the bag opening cleaning component air outlet 11 are installed on the bag opening cleaning component 9. The bag opening cleaning component 9 is used to receive compressed air through the bag opening cleaning nozzle 10 and output compressed air through the bag opening cleaning component air outlet 11.

[0031] Meanwhile, the bag opening cleaning component 9 may also include a first hollow bag opening cleaning component 9-1 and a second hollow bag opening cleaning component 9-2. The second hollow bag opening cleaning component 9-2 is fixed to the outer wall of the suction pipe by a bag opening cleaning component fixing screw 12. The first hollow bag opening cleaning component 9-1 is fitted over the second hollow bag opening cleaning component 9-2, and the edge of the first hollow bag opening cleaning component 9-1 is fixed to the outer wall of the suction pipe. The outer wall of the first hollow bag opening cleaning component 9-1 is provided with a bag opening cleaning nozzle 10 and a bag opening cleaning component air outlet 11. The first hollow bag opening cleaning component 9-1 is used to receive compressed air through the bag opening cleaning nozzle 10 and output compressed air through the bag opening cleaning component air outlet 11. The combined design of the first hollow bag opening cleaning component 9-1 and the second hollow bag opening cleaning component 9-2, through screw fixing and the outer sleeve structure, achieves a more stable compressed air output. This combined design improves the uniformity and efficiency of bag opening cleaning, ensures that there is no material residue at the bag opening, and further improves the sealing quality. In addition, the aforementioned contact sensor 4 enables a combination of suction modes at different depths in the bag.

[0032] In addition to the air extraction assembly and the bag opening cleaning assembly, the air extraction and bag opening cleaning device may also include a bag-shaking assembly. The bag-shaking assembly includes a material tray 21, a bag-shaking cylinder 23, a bag-shaking cylinder piston rod, a first bag-shaking nozzle 22, and a second bag-shaking nozzle 24. The material tray 21 is mounted on the bag-shaking cylinder piston rod. One end of the bag-shaking cylinder 23 is equipped with the first bag-shaking nozzle 22 and connected to the bag-shaking cylinder piston rod, and the other end is equipped with the second bag-shaking nozzle 24. The bag-shaking cylinder 23 is used to drive the material tray 21 to move up and down. The bag-shaking cylinder drives the material tray 21 to move up and down, realizing the bag-shaking operation to assist the air extraction process. The addition of the bag-shaking assembly significantly improves the air extraction effect. By shaking the bag up and down, the material inside the packaging bag becomes looser, making it easier for air to be extracted, thereby reducing the amount of residual air inside the bag.

[0033] The suction assembly, bag opening cleaning assembly, and bag tipping assembly together constitute a suction and bag opening cleaning device. The suction and bag opening cleaning device also includes a fixing assembly, which comprises a support column 18, a top support rod 15, a bottom support rod 19, a base 20, and a fixing block 17. The support column 18 is fixedly mounted on the base 20. The top support rod 15 is fixedly mounted on the top of the support column 18 via the fixing block 17. The fixing block 17 is fixed to the support column 18 via fixing assembly screws 16. The bottom support rod 19 is fixedly mounted on the bottom of the support column 18. The piston rod 6 of the push cylinder is connected to the push cylinder 3 via the top support rod 15. The suction assembly also includes a fixing screw 2, with the cylinder fixed to the top support rod 15 via the fixing screw 2. The bag tipping cylinder 23 is mounted on the bottom support rod 19. This structural design ensures the stability and reliability of the device, allowing suction and bag opening cleaning operations to be performed in a stable environment, improving overall work efficiency and safety.

[0034] This application also provides a pre-packaging bag machine, wherein the pre-packaging bag machine is equipped with the aforementioned air extraction and bag opening cleaning device. By combining the pre-packaging bag machine with the air extraction and bag opening cleaning device, the entire process from material filling to sealing is automated, greatly improving packaging efficiency and product quality.
