[0002] Bag-feeding packaging machines are commonly used for packaging of various foods, medicines, daily chemicals, hardware and other items. Common packaging machines include bag-feeding devices, conveying devices, weighing devices, filling devices, and sealing devices. These devices work together to ensure the continuity and efficiency of the packaging process, and can quickly and accurately automatically package various items in designated packaging bags. Its advantages include high degree of automation, high production efficiency, strong adaptability, reliable sealing quality, simple operation, and convenient maintenance.

[0003] When a common continuous bag feeding packaging machine is in use, its internal conveying device, sealing device, bag feeding device, etc. all operate separately. Usually, the packaging bag is placed on the stepping clamp through a clamping suction cup, and the packaging bag is driven by the stepping device to move to the bottom of the filling device in sequence. When the packaging bag is filled, the packaging bag and the material inside it are transported to the sealing device for sealing through the conveying device. Multiple devices need to cooperate with each other to perform bag feeding and packaging. When in use, it is impossible to feed, convey, open and seal the bag at the same time through the internal conveying device. When multiple devices cooperate with each other, if an error occurs in one of the devices, the bag feeding and packaging effect of the subsequent devices will be deviated. Summary of the invention

[0037] As a technical optimization scheme of the present invention, a fixing block 28 is installed between the first threaded sleeve 26 and the second threaded sleeve 27, and threaded rods 29 are installed at both ends of the fixing block 28. The two threaded rods 29 are respectively threadedly installed inside the first threaded sleeve 26 and the second threaded sleeve 27, and the opposite surfaces of the two support plates 20 located at the same end inside the frame 1 are installed with heating plates 25 in the length direction, and the side of the heating plate 25 is abutted against the inner wall of the flexible steel sheet 12; the heating plate 25 can heat the flexible steel sheet 12 on its side, and heat and seal the top of the packaging bag through the heat received by the flexible steel sheet 12.

[0038] As a technical optimization scheme of the present invention, a placing rack 9 is installed at one end of the frame 1 away from the heating plate 25, and material discharge troughs 30 are provided on both sides of the placing rack 9. One end of the two material discharge troughs 30 are interconnected with the interior of the frame 1, and a fixing steel sheet 31 is installed at the inner bottom of the two material discharge troughs 30 close to the end of the frame 1. A fixing hole 32 is opened on the side of the fixing steel sheet 31, and the end of the fixing hole 32 close to the inner wall of the material discharge trough 30 passes through the fixing steel sheet 31; the staff can place a certain amount of packaging bags inside one of the material discharge troughs 30 according to the usage, so as to facilitate the automatic taking of the packaging bags when packaging and sealing the packaging bags.

[0039] As a technical optimization scheme of the present invention, the two fixed steel sheets 31 are respectively located on the side surfaces of one end of the two conveyor belts 11 close to the placement rack 9, and the second clamping plates 33 are slidably installed inside the two discharge troughs 30. The second clamping plates 33 are located between the inner wall of the discharge trough 30 away from the frame 1 and the fixed steel sheet 31. A number of second springs 34 are installed between the second clamping plates 33 and the inner wall of the discharge trough 30. The inner walls of the two discharge troughs 30 are provided with guide grooves 15 at the corner positions of one end close to the frame 1, and the fixed steel sheet 31 is located on the side surfaces of the guide grooves 15. When the packaging bag moves from the inside of the discharge trough 30, one end of the packaging bag can slide from the guide groove 15 to between the two conveyor belts 11 through the connection and drive with the suction cup 19.

[0040] As a technical optimization solution of the present invention, L-shaped protective plates 4 are installed on both sides of the frame 1, and the top ends of the two protective plates 4 are respectively installed at the bottom of the two ends of the frame 1. The conveyor belt 11 is located at the middle end of the side of the frame 1 and is located inside the protective plate 4. A first clamping plate 16 is slidably installed on the inner bottom of the protective plate 4. A plurality of first springs 17 are installed between the first clamping plate 16 and the inner wall of the frame 1. The position of the conveyor belt 11 at the middle end of the side of the frame 1 is located between the first clamping plate 16 and the inner wall of the protective plate 4; the protective plate 4 can provide better support and position limitation for the position of the conveyor belt 11 on the side of the frame 1.

[0041] As a technical optimization solution of the present invention, motors 10 are installed on both sides of the frame 1 near the corners, the motor 10 is located below the conveyor belt 11, and a transmission wheel 22 is installed on the top of the output shaft of the motor 10. The two transmission wheels 22 on the same side are respectively located at the two ends of the inside of the same conveyor belt 11, and the transmission wheel 22 and the inside of the conveyor belt 11 are abutted against each other; the motor 10 can drive the conveyor belt 11 to rotate through the transmission wheel 22, and the packaging bags are taken, loaded and sealed through the conveyor belt 11.

[0042] As a technical optimization scheme of the present invention, support columns 2 are installed at both ends of the frame 1 near the corners, and through holes 18 are opened on the sides of the support columns 2. The two ends of the conveyor belt 11 are respectively located in the through holes 18 on the two support columns 2 on the same side of the two ends of the frame 1. Cooling plates 14 are installed on the inner walls on both sides of the through holes 18, and the position of the conveyor belt 11 inside the through holes 18 is located between the two cooling plates 14; after the heating plate 25 heats the flexible steel sheet 12 to seal the packaging bag, the cooling plate 14 can dissipate heat and cool the flexible steel sheet 12 moved to the inside of the through holes 18, and the cooling plate 14 is interconnected with the external refrigeration equipment.

[0043] As a technical optimization scheme of the present invention, a funnel-shaped storage box 3 is installed above the frame 1, and the top ends of the four support columns 2 are respectively installed at the corners of both sides of the storage box 3. A plurality of feed pipes 7 are installed at the middle end of the bottom of the storage box 3 in the length direction. A control valve 8 is installed on the outer wall of the feed pipe 7. The top end of the control valve 8 is installed at the bottom of the storage box 3, and the feed pipe 7 is located above the opposite surfaces of the two conveyor belts 11. When in use, the staff can place the material to be packaged in the storage box 3 in advance, and a certain amount of material can be transported to the inside of the packaging bag through the control valve 8 when in use.

[0044] As a technical optimization solution of the present invention, a top plate 5 is installed at the middle end of the top of the storage box 3, and rotating plates 6 are rotatably installed at both ends of the top plate 5. The rotating plates 6 are located on the tops of the two support columns 2 at the same end, and placement grooves 13 are opened at the tops of both ends of the frame 1; when in use, the support columns 2 can not only cool the flexible steel sheet 12, but also fix the frame 1, and can also provide good support for the storage box 3.

[0045] When the present invention is used, the staff rotates the rotating plates 6 at both ends of the top plate 5 so that the two ends of the storage box 3 are connected to the outside respectively, and the staff can put the materials to be packaged from the two ends of the top plate 5 into the storage box 3 respectively, and store the materials for a short time through the storage box 3. The staff puts a certain amount of packaging bags to be used inside one of the material discharge slots 30 on the placement rack 9, and the packaging bags are located between the fixed steel sheet 31 and the second clamping plate 33. When in use, a plurality of second springs 34 push the second clamping plate 33 to move through their own elasticity, so that the second clamping plate 33 cooperates with the fixed steel sheet 31 to clamp a plurality of packaging bags. When in use, due to the elasticity of the second spring 34 and the squeezing of the packaging bag by the second clamping plate 33, the position of the packaging bag close to the fixing hole 32 bulges toward the inside of the fixing hole 32, and the thickness of the fixing steel sheet 31 itself is relatively thin, and the fixing steel sheet 31 is located on the side of one end of the conveyor belt 11. Therefore, when the conveyor belt 11 rotates, the suction cup 19 on the conveyor belt 11 that rotates to the position of the fixing steel sheet 31 will abut against the surface of the packaging bag located inside the fixing hole 32 on the side of the frame 1, and the suction cup 19 will be adsorbed on the surface of the packaging bag.

[0046] When in use, the staff can drive the driving wheel 22 to rotate inside the conveyor belt 11 through the motor 10, and the driving wheel 22 abuts against the inner wall of the conveyor belt 11, so when in use, the conveyor belt 11 can be driven to move by the friction between the driving wheel 22 and the inner wall of the conveyor belt 11, and the suction cup 19 on it is adsorbed on the surface of the packaging bag located inside the fixing hole 32. When the suction cup 19 is adsorbed on the surface of the packaging bag, it will continue to move, and the suction cup 19 pulls the adsorbed packaging bag to move, so that one end of the packaging bag moves from the gap between the guide groove 15 and the fixed steel sheet 31 toward the direction of the frame 1, and moves with the conveyor belt 11 to between the two conveyor belts 11 inside the frame 1.

[0047] Both ends of the two conveyor belts 11 located inside the frame 1 are supported by support rods 21 and support plates 20. The support plates 20 can push the inner wall of the conveyor belts 11 to tighten the support plates 20 in the direction away from the inner wall of the frame 1. The positions where the two conveyor belts 11 enter the frame 1 abut against each other. When the packaging bag enters between the two conveyor belts 11 as the conveyor belts 11 move, the two conveyor belts 11 will clamp the packaging bag. When in use, the top of the packaging bag is located between the two flexible steel sheets 12 on the two conveyor belts 11, and the position below the top of the packaging bag abuts against the opposite surfaces of the two conveyor belts 11. When the two conveyor belts 11 clamp the two sides of the packaging bag, the several suction cups 19 on the opposite surfaces of the two conveyor belts 11 can be adsorbed on the two sides of the packaging bag.

[0048] When in use, the two conveyor belts 11 are slidably mounted with the limiting iron sheet 23 on the opposite surfaces of the middle end of the frame 1, and the limiting iron sheet 23 is connected to the inner wall of the frame 1 through the first threaded sleeve 26, the threaded rod 29, the fixing block 28 and the second threaded sleeve 27, so that the staff can adjust the distance between the first threaded sleeve 26 and the second threaded sleeve 27 by rotating the fixing block 28, and the limiting iron sheet 23 drives the flexible steel sheet 12 and the conveyor belt 11 to move toward the inner wall of the frame 1 for the position of the middle end of the frame 1, so that a groove is formed in the middle end of the opposite surfaces of the two conveyor belts 11, and the limiting iron sheet 23 can play a better position adjustment for the opposite surface position of the conveyor belt 11. When the conveyor belt 11 moves to the position of the middle end of the frame 1, the two conveyor belts 11 will be tilted and moved toward the inner wall of the frame 1 respectively, and drive the two sides of the packaging bag respectively, so that the opening of the packaging bag is opened.

[0049] When in use, the thickness of the limiting iron sheet 23 is relatively thin, so when the packaging bag moves and the opening is opened, the limiting iron sheet 23 is located between the packaging bag surface and the flexible steel sheet 12, and will not affect the adsorption of the suction cup 19 to the packaging bag surface. When the packaging bag with the opening opened moves to the bottom of the storage box 3, the feeding pipe 7 located at the bottom of the storage box 3 can transport the material stored in the storage box 3 to the inside of the packaging bag. When in use, the control valve 8 located on the feeding pipe 7 can control the amount of material transported by the feeding pipe 7, thereby reducing the deviation of the amount of material in several packaging bags.

[0050] When the packaging bag is filled with materials, the conveyor belt 11 continues to drive the packaging bag and the materials therein to move away from the placement rack 9 through the suction cup 19 until the packaging bag is clamped and conveyed by the two conveyor belts 11 again. When in use, the two support plates 20 away from one end of the placement rack 9 can not only drive the two conveyor belts 11 to clamp the packaging bag, but also heat the surface of the flexible steel sheet 12 through the heating plate 25 on the support plate 20. When the flexible steel sheet 12 and the conveyor belt 11 clamp and convey the packaging bag, the heated flexible steel sheet 12 can heat both sides of the top of the packaging bag, and the film on the inner wall on both sides of the top of the packaging bag will melt when heated. When the two conveyor flexible steel sheets 12 clamp the top of the packaging bag, the melted films on both sides of the top of the packaging bag can be made to stick together, so as to achieve the effect of sealing the packaging bag.

[0051] When the two conveyor belts 11 move out of the rack 1, the two conveyor belts 11 will move away from the opposite surface, so that the two conveyor belts 11 break the clamping of the packaging bag, and the packaging bag can fall to the outside, or the staff outside can take and store the broken packaging bag. When the conveyor belts 11 and the flexible steel sheet 12 break the clamping of the packaging bag, they will move to the inside of the through hole 18 on the support column 2, and the cooling plates 14 on the inner walls of the through hole 18 on both sides are connected to the external refrigeration equipment. When the heated flexible steel sheet 12 moves to the inside of the through hole 18 with the conveyor belt 11, the two cooling plates 14 can quickly cool the surface of the flexible steel sheet 12. When the cooled flexible steel sheet 12 moves out of the through hole 18, it will move again in the direction of the placement rack 9, and while moving, the flexible steel sheet 12 will contact the outside air, so that the surface of the flexible steel sheet 12 gradually becomes normal temperature, which is convenient for the conveyor belt 11 and the flexible steel sheet 12 to take, clamp, convey and seal the packaging bag again.

[0052] When in use, the top of the protective plate 4 is installed at the bottom of the top of the frame 1, and the bottom of the protective plate 4 is installed on the side of the bottom end of the frame 1. The first spring 17 can move the first clamping plate 16 inside the protective plate 4 through its own elasticity, so that the first clamping plate 16 continues to push the conveyor belt 11, and the conveyor belt 11 can always be kept in a taut state when in use. When the staff adjusts the position of the conveyor belt 11 at the middle end of the frame 1 through the fixing block 28 and the threaded rod 29, the conveyor belt 11 can also be quickly put in a taut state, so that the conveyor belt 11 and the flexible steel sheet 12 can better perform continuous bag packaging and sealing when in use.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
