Description

TECHNICAL FIELD

[0001] The utility model relates to packing technical field especially, it relates to a ventilation device and packing equipment. BACKGROUND

[0002] The battery industry has high requirements for battery materials, and the presence of magnetic foreign matter in the battery material can cause self-discharge, reduce battery life, and even cause safety accidents; in addition, battery materials are prone to caking when exposed to moisture, oil mist, and other substances, affecting product quality.

[0003] The empty packaging bag used in the battery field is divided into a chemical fiber woven outer bag that can withstand pressure and an inner bag made of plastic film that is sealed. In order to facilitate transportation and storage, the empty packaging bag is generally folded and stacked, and before use, it needs to be inflated and expanded before filling with materials; if the materials are directly filled, the inner bag is prone to damage due to uneven stress at the creases during filling, causing the materials to leak from the outer bag, or contaminated air / water entering through the damaged area, affecting the quality of the materials. Therefore, the packaging bag must be fully opened before use, and the inner bag must be attached to the outer bag. At the same time, the opened packaging bag is also convenient for checking whether the packaging bag is intact and whether there are foreign objects inside the packaging bag.

[0004] The prior art usually uses air generated by a stainless steel centrifugal fan to blow the packaging bag. However, the air often contains moisture, oil mist, dust, and other impurities. Moisture and oil mist can cause battery material powder products to absorb moisture and clog, and magnetic foreign matter such as metal particles in the dust can easily cause pollution and affect the quality of battery material products.

[0046] Embodiments

[0047] Please refer to Figure 1 The present embodiment provides a breather device 100 for connecting a gas supply device (not shown in the figure) and a packaging bag 10. The breather device 100 includes a breather pipe 110, and a valve mechanism 120, a filter mechanism 130 and a gas distribution mechanism 140 fixed in sequence on the breather pipe 110, the valve mechanism 120 being located on the side of the filter mechanism 130 close to the gas supply device.

[0048] When using the breather device 100 described above, the breather device 100 is connected to the gas supply device and the packaging bag 10 respectively. The air provided by the gas supply device enters the breather pipe 110 and flows through the valve mechanism 120, the filter mechanism 130 and the gas distribution mechanism 140 in sequence. In this process, the filter mechanism 130 filters the moisture and foreign matter in the air, ensuring that no dust particles, water mist, oil mist and other impurities are introduced when the packaging bag 10 is inflated, avoiding the occurrence of moisture absorption and caking when the product is packaged in the packaging bag 10, and avoiding the product from being contaminated.

[0049] The packaging bag 10 can be exemplarily a 25Kg packaging bag, a 50Kg packaging bag, a small ton bag with a loading capacity of 0.5-1 ton, a medium ton bag with a loading capacity of 1-2 tons, a large ton bag with a loading capacity of 2-3 tons, and the product packaged therein is a powder-like battery material which is sensitive to moisture and dust in the air.

[0050] In addition, the packaging bag 10 is composed of a bag body 10a and a sling 10c, and the bag body 10a has an upper opening 10b.

[0051] In some embodiments, the ventilation pipe 110 is made of plastic hose. In addition, the ventilation pipe 110 is divided into multiple sections, which are connected between the air supply device and the valve mechanism 120, between the valve mechanism 120 and the filtering mechanism 130, and between the filtering mechanism 130 and the air distribution mechanism 140, etc.

[0052] In some embodiments, the valve mechanism 120 includes an electromagnetic pulse valve 121 and / or an air source pressure regulating valve 122.

[0053] The electromagnetic pulse valve 121 can control the inflation time, and the air source pressure regulating valve 122 can adjust the pressure of the air flow in the ventilation pipe 110 during inflation.

[0054] It can be understood that the valve mechanism 120 can only include the electromagnetic pulse valve 121. Alternatively, the valve mechanism 120 can only include the air source pressure regulating valve 122. Alternatively, the valve mechanism 120 can include both the electromagnetic pulse valve 121 and the air source pressure regulating valve 122. The present embodiment does not limit this.

[0055] When the valve mechanism 120 includes both the electromagnetic pulse valve 121 and the air source pressure regulating valve 122, the electromagnetic pulse valve 121 and the air source pressure regulating valve 122 are connected in series through a section of the ventilation pipe 110.

[0056] In other embodiments, the valve mechanism 120 includes a stainless steel ball valve, which is manually opened and closed by the staff.

[0057] In some embodiments, the filtering mechanism 130 includes 2-5 filters connected in series, and the filters include a micro-mist filter 131.

[0058] Using multiple filters connected in series can improve the filtering effect of impurities such as dust particles, water mist, and oil mist.

[0059] Optionally, the number of filters is three. In addition, the micro-mist filter 131 is used to filter particles with a diameter of not less than 0.01 μm, including solid particles and liquid droplets, etc.

[0060] In other embodiments, the filters can also include a water mist filter and a smoke filter, and the water mist filter and the smoke filter are connected in series.

[0061] In some embodiments, the air distribution mechanism 140 includes a filter rod 141. The upper end of the filter rod 141 is connected to the ventilation pipe 110, and the lower end of the filter rod 141 is inserted into the packaging bag 10, specifically inserted into the upper opening 10b of the packaging bag 10.

[0062] At this time, the filter stick 141 is used as the end gas outlet structure of the entire aeration device 100, and adopts a filter stick interception form, which can not only intercept foreign matters, but also adjust the aeration speed and local airflow pressure of the packaging bag 10, so as to prevent the inner bag of the packaging bag 10 from being damaged or causing a safety accident due to excessive local aeration.

[0063] Correspondingly, the aeration device 100 further includes a movable first support 150. The first support 150 is connected with the air distribution mechanism 140, that is, the first support 150 is connected with the filter stick 141, and is used to move the filter stick 141.

[0064] In use, the first support 150 drives the filter stick 141 to move, so that the filter stick 141 is inserted into the upper opening 10b of the packaging bag 10, and the packaging bag 10 is aerated. After the aeration is completed, the first support 150 drives the filter stick 141 to move out of the upper opening 10b of the packaging bag 10, so as to transfer the packaging bag 10 to the next process.

[0065] Exemplarily, the first support 150 can be a pneumatic cylinder. The piston rod of the pneumatic cylinder extends and retracts in the vertical direction, thereby driving the filter stick 141 to ascend and descend, and the filter stick 141 is inserted into the upper opening 10b of the packaging bag 10 when descending.

[0066] In some embodiments, the filter stick 141 is in a hollow cylindrical shape, and the outer diameter of the filter stick 141 is 30mm-50mm, and the inner diameter of the filter stick 141 is 20mm-28mm.

[0067] Optionally, the outer diameter of the filter stick 141 can be 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 44mm, 46mm, 48mm, 50mm, or any value between 30mm and 50mm. In addition, the inner diameter of the filter stick 141 can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, or any value between 20mm and 28mm.

[0068] Exemplarily, the outer diameter of the filter stick 141 is 40mm, and the inner diameter of the filter stick 141 is 24mm.

[0069] In some embodiments, the length of the filter stick 141 is 400mm-600mm.

[0070] Optionally, the length of the filter stick 141 can be 400mm, 420mm, 440mm, 460mm, 480mm, 500mm, 520mm, 540mm, 560mm, 580mm, 600mm, or any value between 400mm and 600mm.

[0071] Exemplarily, the length of the filter rod 141 is 500 mm.

[0072] In some embodiments, the side wall of the filter rod 141 has a plurality of through holes with a size of 0.1-0.5 μm.

[0073] Optionally, the size of the through holes on the side wall of the filter rod 141 can be 0.1 μm, 0.2 μm, 0.3 μm, 0.4 μm, 0.5 μm or any value between 0.1 μm and 0.5 μm, and the number of the through holes can be 1000, 20000, 50000, etc.

[0074] Exemplarily, the size of the through holes on the side wall of the filter rod 141 is 0.3 μm. In this case, the filter rod 141 is used to filter particles with a diameter not less than 0.3 μm, including solid particles and liquid droplets, etc. In addition, the material of the filter rod 141 is polyethylene.

[0075] Exemplarily, the inner diameter of the filter rod 141 is larger than that of the air passage 110. The inner diameter of the air passage 110 is 12 mm, and the inner diameter of the filter rod 141 is 25 mm.

[0076] In summary, the filter mechanism 130 and the filter rod 141 in the air passage device 100 can filter the moisture, oil mist and foreign matters in the air in sequence, so as to ensure that no dust particles, water mist, oil mist and other impurities are introduced when the packaging bag 10 is inflated, avoid the situation that the product is absorbed moisture and blocked when the product is packaged by using the packaging bag 10, and avoid the product being polluted. At the same time, the filter rod 141 can adjust the air flow distribution discharged from the end of the air passage device 100, reduce the downward air flow speed, control the inflation speed of the packaging bag 10, and prevent the inner bag of the packaging bag 10 from being damaged or causing a safety accident due to local over-inflation.

[0077] Please refer to Figure 2 The embodiment also provides a packaging equipment, which comprises an air supply device (not shown in the figure) and the air passage device 100.

[0078] In use, the air supply device directly supplies air to the air passage 110, and the air supplied by the air supply device flows along the air passage 110 and is finally discharged through the through holes on the inner side wall and the outer side wall of the filter rod 141.

[0079] It can be understood that the air supply device can be a stainless steel centrifugal fan or an original air compressor in a workshop. When the original air compressor in the workshop is used as the air supply device, the surplus compressed air in the workshop can be fully utilized, and the equipment operation energy consumption and maintenance cost can be reduced.

[0080] In some embodiments, the packaging device further comprises at least one of a movable support frame 200, a detection device 300, a filling device (not shown in the figure), and a sealing device (not shown in the figure).

[0081] Specifically, the movable support frame 200 supports the packaging bag 10 and drives the packaging bag 10 to move between the aeration device 100, the filling device, and the sealing device.

[0082] When the packaging bag 10 moves to the aeration device 100, the aeration device inflates the packaging bag 10 through the aeration pipeline 110. When the packaging bag 10 moves to the filling device, the filling device fills the packaging bag 10. When the packaging bag 10 moves to the sealing device, the sealing device seals the packaging bag 10.

[0083] In addition, the support frame 200 takes the position where the aeration device 100 is located as the initial position. After the packaging bag 10 that is completely packaged is unloaded, the support frame 200 returns to the initial position.

[0084] In this process, the detection device 300 detects the packaging bag 10, including but not limited to: detecting whether the packaging bag 10 is hung on the support frame 200, whether the packaging bag 10 is inflated, whether the packaging bag 10 is damaged and leaks, whether foreign matter enters the packaging bag 10, etc.

[0085] Among them, the specific structure of the filling device and the sealing device belongs to mature technology, and this embodiment does not make redundant description.

[0086] In some embodiments, the packaging device further comprises a movable support frame 200. The support frame 200 is provided with a hanging piece 210, and the hanging strap 10c of the packaging bag 10 is hung on the hanging piece 210.

[0087] Exemplarily, the movable support frame 200 can be provided with a carrying trolley at the bottom and moved through the carrying trolley. In addition, the hanging piece 210 adopts a hook, and the hanging piece 210 is provided with two, and the hanging straps 10c on both sides of the packaging bag 10 are hung on the corresponding hanging pieces 210 respectively.

[0088] In some embodiments, the packaging device further comprises a detection device 300 and a movable support frame 200. The detection device 300 is used for detecting the packaging bag 10, and the detection device 300 comprises at least one of a first detection mechanism 310, a second detection mechanism 320, and a third detection mechanism 330.

[0089] Specifically, the first detection mechanism 310 comprises a detection container 311. The detection container 311 comprises a side wall 311a and a bottom 311b connected to each other, the side wall 311a is arranged on two opposite sides of the bottom 311b, the side wall 311a and the bottom 311b enclose a cavity 311c in which the bag body 10a of the packaging bag 10 is placed, and the side wall 311a and the bottom 311b are both provided with a photoelectric sensor 312. The photoelectric sensor 312 can adjust the position according to the edge of the packaging bag 10 after inflation.

[0090] When inflated, the bag body 10a of the packaging bag 10 is placed in the cavity 311c. As the inflation process proceeds, the bag body 10a of the packaging bag 10 gradually expands. When the bag body 10a of the packaging bag 10 expands to block the light of any one of the photoelectric sensors 312 on the side wall 311a and the bottom 311b, the air flow rate in the ventilation pipeline 110 is reduced through the pressure regulating valve 122 of the air supply device. When the bag body 10a of the packaging bag 10 continues to expand to block the light of three photoelectric sensors 312 on the side wall 311a and the bottom 311b at the same time, it indicates that the packaging bag 10 is fully expanded.

[0091] Therefore, the first detection mechanism 310 can detect the inflation process of the packaging bag 10, guide the air supply device and the ventilation device 100 to inflate the packaging bag 10.

[0092] Specifically, the second detection mechanism 320 comprises a movable second support 321. The second support 321 is inserted into the packaging bag 10, specifically inserted into the upper opening 10b of the packaging bag 10, and the second support 321 is provided with a pressure sensor 322 and / or a camera 323.

[0093] When the packaging bag 10 is fully expanded, the air supply device continues to inflate the packaging bag 10 through the ventilation pipeline 110. At this time, the movable second support 321 is inserted into the upper opening 10b of the packaging bag 10, and the pressure sensor 322 and / or the camera 323 are extended into the interior of the packaging bag 10.

[0094] The pressure sensor 322 tests the pressure inside the packaging bag 10. If the pressure tested by the pressure sensor 322 is equal to the preset pressure, it indicates that the packaging bag 10 is not damaged. Otherwise, if the pressure tested by the pressure sensor 322 is less than the preset pressure, it indicates that the packaging bag 10 is damaged and cannot be used in the next process.

[0095] In addition, camera 323 takes pictures of the inner surface of packaging bag 10. If the picture taken by camera 323 is consistent with the preset picture, and manual inspection shows no foreign objects or impurities brought in by materials in the picture taken by camera 323, it indicates that no foreign objects have entered the packaging bag 10; otherwise, it indicates that foreign objects have entered the packaging bag 10 and it cannot be used in the next process. Alternatively, if manual inspection shows no outer pressure-bearing woven chemical fiber outer bag in the picture taken by camera 323, it indicates that the inner bag of packaging bag 10 is not damaged; otherwise, it indicates that packaging bag 10 is damaged and it cannot be used in the next process.

[0096] Therefore, the second testing agency 320 can detect whether the packaging bag 10 is damaged or has foreign objects entering it, and thus determine whether the packaging bag 10 can be used.

[0097] After the second testing mechanism 320 completes its testing, the electromagnetic pulse valve 121 closes, stopping the inflation. The first support 150 and the second support 321 move upwards, causing the filter rod 141, pressure sensor 322, and camera 323 to leave the opening of the packaging bag 10. Subsequently, the support frame 200 moves the packaging bag 10 to the filling device, specifically moving the opening of the packaging bag 10 to the lower part of the filling port of the filling device so that the filling device can fill the packaging bag 10.

[0098] Understandably, the second bracket 321 may only have a pressure sensor 322 installed. Alternatively, the second bracket 321 may only have a camera 323 installed. Or, the second bracket 321 may have both a pressure sensor 322 and a camera 323 installed simultaneously.

[0099] Specifically, the third detection mechanism 330 includes a weight sensor 331, which is mounted on a movable support frame 200.

[0100] When the support frame 200 is in its initial position, the straps 10c of the packaging bag 10 are suspended from the suspension member 210, and the filter rod 141 is inserted into the upper opening 10b of the packaging bag 10. At this time, if the weight sensor 331 detects that the increased weight matches the weight of the empty packaging bag 10, it indicates that the packaging bag 10 is properly suspended. Based on this, the electromagnetic pulse valve 121 opens, and compressed air is introduced.

[0101] In addition, after filling is completed, the staff removes the packaging bag 10. When the weight sensor 331 detects no weight, the support frame 200 returns to its initial position.

[0102] Therefore, the third detection mechanism 330 can detect whether there is an empty packaging bag 10 hanging on the support frame 200, which serves as the basis for opening the electromagnetic pulse valve 121, and detect whether the filled packaging bag 10 has been removed from the support frame 200, so as to guide the support frame 200 to reset.

[0103] In some embodiments, the packaging device further comprises a movable support frame 200, a detection device 300, a filling device (not shown in the figure), a sealing device (not shown in the figure), and a controller. The controller controls the aeration device 100, the support frame 200, the detection device 300, the filling device, and the sealing device to realize automatic packaging.

[0104] The structure of the support frame 200 and the detection device 300 is the same as that of the foregoing embodiments, and will not be described here.

[0105] In some embodiments, the controller is in communication with the valve mechanism 120 and is configured to control the flow rate of the gas in the aeration pipe 110.

[0106] Specifically, the controller is in communication with the electromagnetic pulse valve 121 and the gas source pressure regulating valve 122, respectively, and controls the inflation time by controlling the opening and closing of the electromagnetic pulse valve 121, and adjusts the flow rate of the gas in the aeration pipe 110 by controlling the gas source pressure regulating valve 122, thereby controlling the flow rate of the gas in the aeration pipe 110.

[0107] In some embodiments, the controller is in communication with the movable support frame 200 and is configured to control the movement of the packaging bag 10 between the aeration device 100, the filling device, and the sealing device by the support frame 200.

[0108] In some embodiments, the detection device 300 comprises at least a first detection mechanism 310. The controller is in communication with the first detection mechanism 310 and is configured to output a stop inflation signal after the photoelectric sensor 312 senses the packaging bag 10.

[0109] It can be understood that after the controller outputs the stop inflation signal, the electromagnetic pulse valve 121 can be closed by the staff to stop inflating the packaging bag 10. Alternatively, the controller can also be in communication with the electromagnetic pulse valve 121 to automatically control the electromagnetic pulse valve 121 to close.

[0110] In some embodiments, the detection device 300 comprises at least a second detection mechanism 320. The controller is in communication with the second detection mechanism 320 and is configured to control the second detection mechanism 320 to detect the packaging bag 10 after the aeration device 100 inflates the packaging bag 10.

[0111] In some embodiments, the detection device 300 comprises at least a third detection mechanism 330. The controller is in communication with the third detection mechanism 330 and is configured to output a start inflation signal after the weight sensor 331 senses that the packaging bag 10 is hung in place, and output a reset signal after the weight sensor 331 senses that the packaging bag 10 is unloaded.

[0112] In some embodiments, the controller is in communication with the filling device and is configured to control the filling device to fill the packaging bag 10.

[0113] In some embodiments, the controller is in communication with the packing and sealing device and is configured to control the packing and sealing device to pack the packaging bag 10.

[0114] For example, the controller is in communication with the valve mechanism 120 and the third detection mechanism 330. When the weight sensor 331 detects an increased weight on the support frame 200 that corresponds to the weight of an empty packaging bag 10, the controller controls the electromagnetic pulse valve 121 to open and start supplying compressed air.

[0115] For example, the controller is in communication with the valve mechanism 120 and the first detection mechanism 310. When any one of the photoelectric sensors 312 senses the bag body 10a of the packaging bag 10, the controller controls the air source pressure regulating valve 122 to reduce the air flow rate in the air supply pipeline 110.

[0116] For example, the controller is in communication with the first detection mechanism 310 and the second detection mechanism 320. When the three photoelectric sensors 312 simultaneously sense the bag body 10a of the packaging bag 10, the controller controls the second support 321 to insert into the upper opening 10b of the packaging bag 10, and then controls the pressure sensor 322 and the camera 323 to detect the quality of the packaging bag 10, and determines whether the packaging bag 10 can be used according to the detection result.

[0117] For example, the controller is in communication with the valve mechanism 120, the first detection mechanism 310, and the second detection mechanism 320. When the three photoelectric sensors 312 simultaneously sense the packaging bag 10, the controller outputs a stop inflating signal, but does not immediately close the electromagnetic pulse valve 121, but controls the second detection mechanism 320 to detect the quality of the packaging bag 10, and controls the electromagnetic pulse valve 121 to close after the detection is completed.

[0118] For example, the controller is in communication with the support frame 200 and the second detection mechanism 320. When the second detection device 300 detects that the packaging bag 10 is intact and has no foreign matter and can be normally used, the controller controls the support frame 200 to move the packaging bag 10 to the filling device, so as to fill the packaging bag 10.

[0119] For example, the controller is in communication with the support frame 200 and the third detection mechanism 330. When the weight sensor 331 detects no weight, i.e., senses that the packaging bag 10 is unloaded, the controller outputs a reset signal and controls the support frame 200 to return to the initial position.

[0120] In the embodiment, the controller is in communication connection with the valve mechanism 120, the support frame 200, the detection device 300, the filling device and the sealing device respectively. When the staff hangs the empty packaging bag 10 on the support frame 200, the controller automatically controls the structures to complete the packaging operation.
