[0002] Powder packaging machine is a general term for equipment for packaging powdery items. Powder packaging machine is suitable for quantitative packaging of powdery, powdery and powdery materials in the chemical, food, agricultural and sideline products and other industries; such as: milk powder, starch, pesticides, veterinary drugs, premixes, additives, condiments, feed, enzyme preparations, etc.; this automatic quantitative packaging machine is suitable for quantitative packaging of powders in various packaging containers such as bags, cans, bottles, etc. The powder packaging machine has no problem packaging larger particles, and the bag shape can remain beautiful. However, when sealing the materials with a metering and dispensing purpose of less than 400, the sealing will not be tight, resulting in powder leakage, loss of materials and packaging bags, and increased costs for the enterprise. In addition, the existing powder packaging machine has a complex structure and slow packaging speed, and is prone to various failures. Utility Model Content

[0003] The technical problem to be solved by the utility model is: how to provide an automatic packaging device for powder products which has a simple structure, a fast packaging speed and is not prone to failure.

[0004] The technical solution adopted by the utility model is: an automatic packaging machine for powder products, including a first paper roll mounting frame 1, a second paper roll mounting frame 2, a first pinching roller 3, a second pinching roller 4, a transmission pinching roller 5, a first edge banding machine 6, a second edge banding machine 7, a feeder 9, a third edge banding machine 10, a fourth edge banding machine 11, and a shearing machine 12. A roll of packaging paper 8 is respectively installed on the first paper roll mounting frame 1 and the second paper roll mounting frame 2. The transmission pinching roller 5 has multiple groups and is arranged vertically. The multiple groups of transmission pinching rollers 5 form a conveying mechanism for the packaging paper 8. The packaging paper on the first paper roll mounting frame 1 The paper 8 is connected to the conveying mechanism through the first clamping roller 3, and the packaging paper roll 8 on the second paper roll mounting frame 2 is connected to the conveying mechanism through the second clamping roller 4. The conveying mechanism is sequentially arranged with the first edge banding machine 6, the second edge banding machine 7, the feeder 9, the third edge banding machine 10, the fourth edge banding machine 11, and the shearing machine 12 along the conveying direction of the packaging paper roll 8. The first edge banding machine 6 is located at the lower side of the conveying mechanism, and the fourth edge banding machine 11 is located at the upper side of the conveying mechanism. The second edge banding machine 7 includes two left and right virtual edge banding devices, and the third edge banding machine 10 includes two left and right real edge banding devices.

[0005] During use, the packaging roll paper 8 installed on the first roll paper mounting rack 1 is continuously unrolled under the action of the first pinch roller 3 and enters the conveying mechanism. The packaging roll paper 8 installed on the second roll paper mounting rack 2 is continuously unrolled under the action of the second pinch roller 4 and enters the conveying mechanism. The two packaging roll papers 8 are aligned and stacked together in the conveying mechanism. When the two packaging roll papers 8 are transported in the conveying mechanism, they first pass through the first edge sealer 6.

Then they pass through the third edge sealer 10, and the two solid connection edge sealing devices of the third edge sealer 10 form two parallel solid connection edge seals. The two parallel solid connection edge seals are between the two parallel pressure virtual connection edge seals, which will not cause the diffusion of drugs, and are encapsulated into one by one connected bags containing materials. Then they pass through the fourth edge sealer 11 to complete the edge sealing of the upper sides of the two packaging roll papers 8, forming one by one connected airtight bags containing materials. Finally, they pass through the shearing machine 12. The shearing machine 12 cuts open from between the two parallel solid connection edge seals to form one bag after another of well-packaged products. A conveyor belt is installed under the shearing machine 12, and the packaged products are transported to the required places by the conveyor belt.

[0022] The structures of the first roll paper mounting rack 1 and the second roll paper mounting rack 2 are the same and are respectively located at the front and rear sides on the left side of the conveying mechanism. The first roll paper mounting rack 1 is a column fixed on the chassis, and the central hollow of the packaging roll paper 8 is sleeved on the column. When dragging the packaging roll paper 8, the packaging roll paper 8 will automatically unwind. When replacing the packaging roll paper 8 on the first roll paper mounting rack 1 and the second roll paper mounting rack 2, it is necessary to wait until there is no packaging roll paper 8 on one or two driving pinch rollers 5 at the front of the conveying mechanism, and pass the packaging roll paper 8 through the first pinch roller 3 or the second pinch roller 4 and guide it to one or two driving pinch rollers 5 at the front of the conveying mechanism. Then start normal operation.

[0023] A roll of packaging roll paper 8 is respectively installed on the first roll paper mounting rack 1 and the second roll paper mounting rack 2. There are multiple groups of driving pinch rollers 5 arranged vertically, and the multiple groups of driving pinch rollers 5 form a conveying mechanism for the packaging roll paper 8. The packaging roll paper 8 on the first roll paper mounting rack 1 is connected to the conveying mechanism through the first pinch roller 3, and the packaging roll paper 8 on the second roll paper mounting rack 2 is connected to the conveying mechanism through the second pinch roller 4. The conveying mechanism is successively arranged with a first edge sealer 6, a second edge sealer 7, a blanking device 9, a third edge sealer 10, a fourth edge sealer 11, and a shearing machine 12 along the conveying direction of the packaging roll paper 8. The first edge sealer 6 is located on the lower side of the conveying mechanism, the fourth edge sealer 11 is located on the upper side of the conveying mechanism, the second edge sealer 7 includes two left and right loosely connected edge sealing devices, and the third edge sealer 10 includes two left and right solidly connected edge sealing devices.

[0024] The structures of the first pinch roller 3 and the second pinch roller 4 are the same and are respectively located at the front and rear sides on the left side of the conveying mechanism and between the first roll paper mounting rack 1 and the second roll paper mounting rack 2. The first pinch roller 3 includes a front roller 21 and a rear roller 22 on a pinch roller support 24. The two sides of the front roller 21 and the rear roller 22 are meshed by gears. One side of the front roller 21 is fixedly connected to the output shaft of the motor 23. The front roller 21 and the rear roller 22 are connected to the pinch roller support 24 through bearings. The motor 23 can be replaced by other power devices as long as it can drive the front roller 21 to rotate.

[0025] The structure of the driving pinch roller 5 is the same as that of the first pinch roller 3. All the driving pinch rollers 5 are on the same horizontal plane and are parallel to each other.

[0026] The first edge sealer 6 and the fourth edge sealer 11 are hot melt edge sealing devices (prior art), and other existing edge sealing devices can also be used as long as they can complete one-side sealing.

[0027] The two virtual edge banding devices of the second edge banding machine 7 are in a symmetrical structure. Each virtual edge banding device includes two telescopic devices 25 and two docking bodies 26 with a cuboid structure. The docking surface of one docking body 26 is a plane, and the docking surface of the other docking body 26 is evenly provided with convex columns 20. The telescopic device can be a hydraulic or pneumatic device. When the docking body 26 is relatively long, the telescopic devices can be multiple arranged in parallel.

[0028] The two solid edge banding devices of the third edge banding machine 10, each solid edge banding device is a hot melt edge banding device. Other existing edge banding devices can also be used as long as they can complete the edge banding of one side for sealing.

[0029] During use, the packaging roll paper 8 installed on the first roll paper mounting rack 1 is continuously unrolled under the action of the first pinch roller 3 and enters the conveying mechanism. The packaging roll paper 8 installed on the second roll paper mounting rack 2 is continuously unrolled under the action of the second pinch roller 4 and enters the conveying mechanism. The two packaging roll papers 8 are aligned and stacked together in the conveying mechanism. When the two packaging roll papers 8 are transported in the conveying mechanism, they first pass through the first edge sealer 6. The first edge sealer 6 completes the edge sealing of the lower sides of the two packaging roll papers 8 (for the convenience of this utility model, the roll papers installed on the first roll paper mounting rack 1 and the second roll paper mounting rack 2 and the unrolled roll papers are all called packaging roll paper 8), so that the lower sides of the two packaging roll papers 8 are stably connected together to form the upper edge seal 17. Then it passes through the second edge sealer 7. The two virtual connection edge sealing devices of the second edge sealer 7 act to form two parallel pressure virtual connection edge seals, namely the first pressure virtual connection edge seal 13 and the second pressure virtual connection edge seal 14. Then it passes through the blanking device 9 (a blanking device using the prior art). The connecting cylinder 19 at the lower part of the blanking device 9 is inserted between the two packaging roll papers 8 to tear open the upper parts of the two parallel pressure virtual connection edge seals. The blanking device 9 completes quantitative blanking. Since the lower parts of the pressure virtual connection edge seals are not torn, a one-by-one bagged structure (the part between the two pressure virtual connection edge seals with a larger distance in adjacent two pressure virtual connection edge seals) is formed on the lower side of the two stacked packaging roll papers 8. There are two parallel pressure virtual connection edge seals between adjacent two bagged structures. When the blanking device 9 blanks, the material is bled into one-by-one bagged structures, and the material will not spread to the outside of each bagged structure. Then it passes through the third edge sealer 10. The two solid connection edge sealing devices of the third edge sealer 10 form two parallel solid connection edge seals, namely the first solid connection edge seal 15 and the second solid connection edge seal 16. The two parallel solid connection edge seals are located between the two parallel pressure virtual connection edge seals (the two pressure virtual connection edge seals with a smaller distance in adjacent two pressure virtual connection edge seals), which will not cause the diffusion of drugs, and are encapsulated into one-by-one connected bags containing materials. Then it passes through the fourth edge sealer 11 to complete the edge sealing of the upper sides of the two packaging roll papers 8, forming one-by-one connected airtight bags containing materials. Finally, it passes through the shearing machine 12. The shearing machine 12 cuts open from between the two parallel solid connection edge seals (the edge seals with a smaller distance in adjacent two solid connection edge seals) to form one-by-one well-packaged packaging products. A conveyor belt is installed under the shearing machine 12, and the packaging products are transported to the required place by the conveyor belt.
