Description

Technical Field

[0001] The invention relates to an inflation heat sealing device, and in particular to a continuous and steady guided inflation heat sealing device for inflating an inflatable packaging bag and a continuous and steady guided inflation heat sealing method. Background Art

[0002] In the traditional pneumatic heat sealing equipment, the heat sealing wheel only plays the role of heat conductive material during the heat sealing process, and the heat sealing performance is not high. In addition, a blade is used to cut the incision after heat sealing to guide the subsequent packaging bag. This method will also cause air leakage during the use of the product. During use, the packaging bag will also be warped due to the blade breaking the incision, affecting the use effect.

[0003] In the process of inflation, the stability of the packaging bag before it enters the inflation tube for inflation is poor. The traditional solution is to use manual hand-held stable transmission into the inflation tube for inflation, or to set a guide wheel in front of the inflation tube. Although it can be easily and smoothly transmitted, it also causes the packaging bag to twist during the transmission process, which will cause transmission obstacles and unsustainable inflation and heat sealing, affecting work efficiency, and it is necessary to manually handle the transmission obstacles. In addition, when entering the inflation tube, the shape of the packaging bag transmitted is uneven, which will cause uneven inflation of each air column during the inflation process, resulting in poor buffering effect and uneven effect, affecting the use effect.

[0004] Traditional inflatable heat sealing equipment uses wire sealing during the heat sealing process, which has a poor heat sealing effect. The thin width of the heat sealing line will cause poor sealing and easy air leakage. In addition, the traditional blade is set after heat sealing to break the packaging bag before it can be guided out of the packaging bag, which is easy to cause cutting errors and defective products, affecting the heat sealing effect. Summary of the invention

[0006] Another object of the present invention is to provide a continuous smooth guided inflation heat sealing device and a continuous smooth guided inflation heat sealing method. The heating wheel adopts non-linear heat sealing such as pattern embossing to avoid leakage of barrier gas due to different individual heat sealing points during the heat sealing process, and can better avoid leakage of heat sealing gas caused by heat sealing errors.

[0007] Another object of the present invention is to provide a continuous smooth guided inflation heat sealing device and a continuous smooth guided inflation heat sealing method, which can maintain smooth transmission of the packaging bag during the entire inflation heat sealing process by adjusting the elevation angle of the film roll placed at multiple locations, adjusting the guide wheel to adjust the transmission friction, setting a convex lens friction wheel, winding the packaging bag around a triangular guide rod, and setting a non-smooth guide wheel with an inclined thread after subsequent heat sealing.

[0059] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0060] like Figures 1 to 10 The figure shows a continuous smooth guided inflation heat sealing device of a preferred embodiment of the present invention, which is used to inflate inflatable packaging bags, and adopts a surface sealing type, especially a non-linear sealing type such as pattern embossing, to avoid leakage of barrier gas due to different individual heat sealing points during the heat sealing process, and can better avoid leakage of heat sealing gas caused by heat sealing errors. In addition, it is a smooth guided inflation heat sealing, which can maintain smooth transmission of the packaging bag during the entire inflation heat sealing process, thereby improving the heat sealing effect.

[0061] The "roll film" in the present invention refers to a plurality of continuous packaging bags that have not been inflated. That is, a plurality of packaging bags that have not been inflated are connected together and arranged in a roll to form a roll film 1000, so as to be transmitted to the continuous stable guiding inflation heat sealing device for inflation.

[0062] Specifically, Figures 1 to 6 As shown, the continuous smooth guided pneumatic heat sealing device comprises a continuous smooth guided pneumatic heat sealing mechanism 100, a fixing plate 800 and a device box 900. The continuous smooth guided pneumatic heat sealing mechanism 100 is fixed to the fixing plate 800, the fixing plate 800 is connected to the device box 900, and the continuous smooth guided pneumatic heat sealing mechanism 100 and the fixing plate 800 are arranged in the device box 900.

[0063] The continuous smooth guided inflation heat sealing mechanism 100 includes an inflation mechanism 10, which can inflate the packaging bags to be inflated. The inflation mechanism 10 also includes an inflation tube 12 and an inflation nozzle 11, and the inflation nozzle 11 is connected to the inflation tube 12. The gas passes through the inflation tube 12 and the inflation nozzle 11, enters the inflation channel 1200 of the roll film 1000 from the inflation nozzle 11, and then enters the inflation port 1100 of each packaging bag to be inflated from the inflation channel 1200, so that each packaging bag of the roll film 1000 can be inflated.

[0064] Specifically, Figures 7 to 9 As shown, the continuous smooth guided inflation heat sealing device further comprises a film roll placement mechanism 200 for placing a film roll 1000. The film roll placement mechanism 200 is arranged near the inflation nozzle 11 of the inflation mechanism 10 of the continuous smooth guided inflation heat sealing mechanism 100, and adopts an elevation angle of 1 to 15 degrees, preferably in the range of 3 to 5 degrees, to prevent the film roll of the packaging bag from falling off due to excessive speed or low quality in the later stage of transmission during the transmission of the packaging bag, so as to smoothly transmit the uninflated packaging bag for inflation by the inflation nozzle 11 of the inflation mechanism 10. A plurality of continuous packaging bags that have not been inflated are arranged in a roll to form a film roll 1000, and are placed in the film roll placement mechanism 200, so as to be transmitted to the continuous smooth guided inflation heat sealing mechanism 100 for inflation.

[0065] Specifically, the film roll placement mechanism 200 includes a film roll support 210, a film roll placement portion 220, an adjustment wheel 230, and a triangular guide rod 240. The film roll placement portion 220, the adjustment wheel 230, and the triangular guide rod 240 are installed on the film roll support 210. The film roll placement portion 220 includes a film roll placement turntable 221 and a film roll fixing shaft 222. The film roll placement turntable 221 is connected to the film roll support 210, and the film roll fixing shaft 222 is connected to the film roll placement turntable 221 for placing the rolled film. The rotation of the film roll placement turntable 221 can drive the rotation of the film roll fixing shaft 222, thereby driving the rolled film to rotate, so that the packaging bag can be continuously inflated by the continuous and stable guided inflation heat sealing mechanism 100.

[0066] Specifically, the roll film 1000 is sleeved on the roll film fixing shaft 222 of the roll film placement part 220 of the roll film placement mechanism 200, and the roll film fixing shaft 222 has an elevation angle of 1 to 15 degrees relative to the horizontal plane, preferably, the range is set to 3-5 degrees. In this way, the roll film placement turntable 221 drives the roll film fixing shaft 222 to rotate the roll film 1000, and during the process of being transmitted to the continuous stable guided inflation heat sealing mechanism 100, the roll film 1000 will not fall off due to reasons such as excessive speed or small mass of the roll film 1000 in the later stage of transmission, thereby smoothly transmitting the packaging bag.

[0067] More specifically, the adjusting wheel 230 can adjust the friction force. That is, the adjusting wheel 230 adjusts the speed of the roll film 1000 during the transmission process and controls the uniformity of the speed by adjusting the friction force between the roll film placement turntable 221 of the roll film placement part 220, so as to avoid the speed of the roll film 1000 being fast or slow during the transmission process, and to avoid the roll film being loose during the transmission process due to uneven speed, so that the packaging bag can be continuously and uniformly transmitted into the inflation nozzle 11 for inflation during the transmission process. More specifically, the adjusting wheel 230 includes a position adjusting block 231 and a contact wheel 232. The contact wheel 232 is connected to the position adjusting block 231 and contacts the roll film placement turntable 221. The contact wheel 232 can generate friction between the roll film placement turntable 221. The position adjusting block 231 is connected to the roll film support 210 and can adjust the position and angle to control the gap between the contact wheel 232 and the roll film placement turntable 221, thereby controlling the magnitude of the friction force, and then controlling the rotation speed of the roll film fixing shaft 222, thereby controlling the transmission speed of the roll film 1000 to the continuous smooth guide inflation heat sealing mechanism 100. In this way, the adjusting wheel 230 can adjust the friction force, thereby stabilizing the continuity and uniformity of the speed at which the roll film 1000 is transmitted to the continuous smooth guide inflation heat sealing mechanism 100.

[0068] like Fig. 9As shown, the triangular guide rod 240 is connected to the film roll support 210 and is arranged on the upper part of the film roll placement part 220, so that the film roll 1000 can be uniformly transported into the inflation nozzle 11, and the packaging bag of the film roll 1000 can be kept in a taut state when entering the inflation nozzle 11, so as to better inflate and subsequently heat seal. Specifically, the triangular guide rod 240 includes a first bottom guide rod 241, a second bottom guide rod 242 and a top guide rod 243, and the first bottom guide rod 241, the second bottom guide rod 242 and the top guide rod 243 form a stable triangular structure, which are all connected to the film roll support 210. One end of the film roll 1000 bypasses and fits the first bottom guide rod 241 and the top guide rod 243, so that the packaging bag of the film roll 1000 can be kept in a taut state when entering the inflation nozzle 11, so as to better inflate and subsequently heat seal. It is understood that in other embodiments, one end of the film roll 1000 may also bypass and fit the second bottom guide rod 242 and the top guide rod 243. The present invention is only taken as an example in this respect and is not limited thereto. It is understood that in other embodiments, there may be only one plate-shaped bottom guide rod, as long as it can form a triangular structure with the top guide rod 243. The present invention is not limited thereto in this respect. Preferably, the triangular guide rod 240 also includes a guide friction block 244. In this preferred embodiment of the present invention, the guide friction block 244 is sleeved on the first bottom guide rod 241, thereby increasing the friction between the triangular guide rod 240 and the film roll 1000, so that when the inflatable packaging bag of the film roll 1000 is kept in a taut state, the inflatable packaging bag will continue to move to the position of the guide friction block 244 during the transmission process, and will not deviate from the position of the packaging bag during the transmission process, and then can smoothly enter the inflation nozzle 11 for inflation. Preferably, the guide friction block 244 is a convex lens friction wheel, which is thin at the edge and thick in the middle, so that during the transmission process, the packaging bag to be inflated will continue to move along the thick position in the middle of the guide friction block 244. It can be understood that in other embodiments, the guide friction block 244 can also be sleeved on the second bottom guide rod 242. The present invention is only taken as an example in this aspect and is not limited thereto.

[0069] like Figures 1 to 6 The figure shows the structure of the continuous smooth guided inflation heat sealing mechanism 100 in the preferred embodiment of the present invention.

[0070] The continuous smooth guided air heat sealing mechanism 100 also includes a plurality of gears 81, a plurality of sprockets 82 and a main motor 91. The main motor 91 drives the rotation of the gears 81 and the sprockets 82. The gears 81 are arranged in parallel, and the sprockets 82 are arranged in parallel to maintain the transmission of the roll film 1000 to the continuous smooth guided air heat sealing mechanism 100.

[0071] The continuous smooth guided inflation heat sealing mechanism 100 also includes a pressing rubber wheel 20, which presses the inflation tube 12 of the inflation mechanism 10, thereby pressing the packaging bag before and after inflation. The pressing rubber wheel 20 is axially connected to the gear 81 and the sprocket 82, and can be driven to rotate and press the packaging bag before and after inflation. In this preferred embodiment of the present invention, the pressing rubber wheel 20 is implemented as four, and the inflation tube 12 is pressed and clamped between the four pressing rubber wheels 20. It can be understood that the number and arrangement position here are only used as examples, and the present invention is not limited thereto in this regard.

[0072] The continuous smooth guided inflation heat sealing mechanism 100 also includes a blade 40 and a cutter motor 92, and the cutter motor 92 drives the blade 40 to rotate to break the packaging bag. The blade 40 is arranged near the compression rubber wheel 40 and the end of the inflation tube 12, so that the packaging bag compressed by the compression rubber wheel 20 is transferred to the blade 40 after inflation, and is promptly transmitted to the heat sealing mechanism for compression and heat sealing. The blade 40 is arranged after inflation and before heat sealing, which can not only break the packaging bag before heat sealing and transfer it into the heat sealing stage, but also the broken position of the packaging bag is compressed and heat sealed after heat sealing, which reduces the impact of the broken opening on subsequent use or the impact of gas leakage due to the broken opening during transmission, thereby avoiding affecting the use effect.

[0073] The continuous smooth guiding inflation heat sealing mechanism 100 further includes a guide wheel 30. The guide wheel 30 is driven by the gear 81 and the sprocket 82, and is disposed near the blade 40. The surface of the guide wheel 30 is non-smooth and has an inclined thread 31, so that the packaging bag can enter the heat sealing process smoothly, and the packaging bag will not be affected by the packaging bag being broken after inflation, thereby avoiding incorrect heat sealing position.

[0074] The elevation angle of the film roll 1000 is adjusted by the film roll fixing shaft 222, the friction force and speed of the film roll 1000 are adjusted by the adjusting wheel 230, the guide friction block 244 of the triangular guide rod 240 implemented as a convex lens friction wheel, the winding method of the triangular guide rod 240 and the inflated packaging bag of the film roll 1000, and the setting of the non-smooth guide wheel 30 with inclined threads after subsequent heat sealing are used to keep the inflated packaging bag of the film roll 1000 smoothly transmitted to the continuous smooth guided inflation heat sealing mechanism 100 during the entire inflation heat sealing process.

[0075] The continuous smooth guided air-inflating heat-sealing mechanism 100 also includes a heating wheel 51, a heating wheel adjusting motor 52 and a heat-insulating cover 53. The guide wheel 30 is arranged between the blade 40 and the heating wheel 51, and the heating wheel 51 is driven by the heating wheel adjusting motor 52 to heat-seal the packaging bag. Preferably, the heating wheel 51 adopts non-linear heat sealing such as pattern embossing to avoid gas leakage due to different blocking points of individual heat sealing points during the heat sealing process, and can better avoid heat sealing gas leakage caused by heat sealing errors. Preferably, the heating wheel 51 that performs heat sealing adopts pattern embossing, and a pattern is arranged on the surface.
