The conveying end includes a conveyor belt 21, a compression conveying structure for receiving the material 4 from the conveyor belt 21 and compressing and conveying it, wherein the material 4 is specifically a sanitary material such as diapers and sanitary napkins. The conveyor belt 21 includes a first conveyor belt 211, and the packaging end includes a placement table 51 arranged corresponding to the connecting channel 6 and placing the packaging bag 3, and a sealing mechanism for pressing and sealing the packaging bag 3 after filling the material 4. The frame 1 is fixedly provided with a first photoelectric switch 7 corresponding to the first conveyor belt 211. The material 4 is conveyed to the compression transmission structure by the first conveyor belt 211 for compression, and then conveyed to the placement table 51 for packaging and sealing after compression. This packaging method has high efficiency and a simple and fast transmission method.

[0024] The conveying end also includes a second conveyor belt 212 connected to the first conveyor belt 211, and the second conveyor belt 212 transmits the material 4 to the first conveyor belt 211, wherein guide plates 23 for guiding the material 4 and preventing the material 4 from deflecting are arranged on both sides of the first conveyor belt 211 and the second conveyor belt 212. A second photoelectric switch 9 for detecting whether there is material 4 passing is arranged on one side of the first conveyor belt 211.

[0025] The compression conveying structure includes a first conveying device 221 disposed on one side of the first conveyor belt 211 and conveying the material 4, a compression device 222 disposed above one side of the first conveying device 221, and a second conveying device 223 conveying the material 4 compressed by the compression device 222 to the connecting channel 6. The upper surfaces of the first conveyor belt 211 and the frame 1 are flush with each other, wherein the first conveying device 221 is disposed on one side of the first conveyor belt 211 and conveys the material 4 on the first conveyor belt 211 to the bottom of the compression device 222, and the second conveying device 223 is disposed on the frame, wherein the compression device 222 compresses in accordance with the plane of the frame 1. The movement of the first conveying device 221 and the movement of the compression device 222 conflict with each other and form a frame-shaped channel for the second conveying device 223 to transmit the material to the connecting channel 6. The compression conveying structure is arranged across both sides of the conveyor belt 21, the first conveying device 221 is arranged on one side of the first conveyor belt 211, and the second conveying device 223 and the compression device 222 are arranged on the other side of the first conveyor belt 211. When conveying the material 4, the first conveying device 221 pushes the material on the first conveyor belt 211 to the bottom of the compression device 222 for compression, and after the compression is completed, it is conveyed by the second conveying device 223. The conveying end of the compression conveying structure corresponds to the connecting channel 6, and the connecting channel 6 corresponds to the packaging end.

[0026] The first conveying device 221 includes a first cylinder 2211 fixedly arranged on the frame 1, and a first contact block 2212 connected to the first cylinder 2211; the compression device 222 includes a second cylinder 2221 vertically fixedly arranged on the frame 1, and a second contact block 2222 connected to the second cylinder 2221; the second conveying device 223 includes a third cylinder 2231 fixedly arranged on the frame 1, and a third contact block 2232 connected to the third cylinder 2231; the telescopic movement direction of the first cylinder 2211, the telescopic movement direction of the second cylinder 2221, and the telescopic movement direction of the third cylinder 2231 are all perpendicular to each other. The first cylinder 2211 pushes the material 4 on the first conveyor belt 211 to the bottom of the compression device 222 by extending, the second cylinder 2221 causes the second resistance block 2222 to compress the material 4 by extending, and the third cylinder 2231 transmits the compressed material 4 to the connecting channel 6 for bagging by extending. This method of transmitting the material 4 is relatively simple. After the material 4 is compressed by the compression device 222, the volume occupied by the material 4 is temporarily reduced, making it more convenient to bag. The telescopic movement direction of the first cylinder 2211, the telescopic movement direction of the second cylinder 2221, and the telescopic movement direction of the third cylinder 2231 are all perpendicular to each other, so that the collision problem that affects the transportation efficiency is avoided during the operation of each component, so that the transmission of the compression conveying structure is more stable and the transmission efficiency is higher.

[0027] The sealing mechanism includes a folding structure 521 for folding the packaging bag 3 and a sealing structure 522 for sealing the bag opening of the packaging bag 3. The folding structure 521 includes a fourth cylinder 5211 arranged on both sides and a folding block 5212 connected to the fourth cylinder 5211. The sealing structure 522 includes a fifth cylinder 5221 arranged at the upper and lower sides respectively and a sealing component 5222 connected to the fifth cylinder 5221. The sealing mechanism is fixed with a control switch 55. The folding block 5212 is driven by the fourth cylinder 5211, so that the folding block 5212 and the bag opening of the packaging bag 3 are mutually abutted to fold the packaging bag 3, so that the bag opening of the packaging bag 3 is flatter for heat sealing operation. The sealing structure 522 drives the sealing component 5222 through the fifth cylinder 5221 and touches the bag opening of the packaging bag for heat sealing. At the same time, the folding structure 521 is respectively arranged on the left and right sides, and the sealing structure 522 is respectively arranged on the upper and lower sides, so that the heat sealing efficiency is higher and the moving line is simpler.

[0028] A control box 11 is disposed in the frame 1 , and the control switch 55 , the first photoelectric switch 7 , and the second photoelectric switch 9 are all electrically connected to the control box 11 .

[0029] The folding block 5212 includes a folding block body 523, a folding platform 524 and a folding vertical block 525 respectively arranged on both sides of the folding block body 523, and the sealing assembly 5222 includes a sealing block 526 and an electric heating plate 527 arranged at the end of the sealing block 526 for heat sealing operation. The folding vertical block 525 and the bag opening are mutually colliding to make the bag opening concave, and the folding platform 524 and the bag opening are mutually colliding to make the bag opening concave, and then the upper and lower surfaces are brought together, and the bag opening is heat-sealed by energizing the electric heating plate. A guide block 5231 is arranged on the folding block body 523, and the arrangement of the guide block 5231 makes the folding block body 523 more rigid and more stable under the drive of the fourth cylinder 5211. An adsorption device 8 for adsorbing the plastic strip separated after the bag opening of the packaging bag 3 is heat-sealed is fixedly arranged below the sealing mechanism, wherein the adsorption device is composed of a vacuum device and an adsorption frame connected to the vacuum device.

[0030] The packaging end further includes a limiting mechanism 53 for limiting the packaging bag 3 placed on the placing table 51 and filled, and the limiting mechanism 53 includes a sixth cylinder 531 arranged on both sides and a limiting block 532 connected to the sixth cylinder 531. The sixth cylinder 531 and the fourth cylinder 5211 are in conflict with each other and their moving lines are parallel to each other. The sixth cylinder 531 extends to make the limiting blocks 532 conflict and limit the two sides of the packaging bag 3 respectively, so as to prevent the packaging bag 3 from swinging left and right and affecting the heat sealing operation.

[0031] The connecting channel 6 includes a movable clamping plate 61 that can move up and down to open or tighten the packaging bag 3. The movable clamping plate 61 includes a seventh cylinder 611 respectively arranged at the upper and lower ends, and a clamping plate 612 connected to the seventh cylinder 611. The clamping plate 612 is composed of a plate body 6121 and vertical edges 6122 fixedly arranged on both sides of the plate body 6121. The movable clamping plate 61 connects the packaging end and the compression conveying structure. The seventh cylinder 611 drives the clamping plate 612 to form a channel between the clamping plates 612 for the material 4 to pass through and be filled into the packaging bag 3. The vertical edges 6122 are arranged on both sides of the plate body 6121 to prevent the material 4 from leaking from both sides during the transmission process.

[0032] A baffle plate 511 is disposed at the end of the placing platform 51, a ninth cylinder 512 is disposed below the placing platform 51 to enable the placing platform 51 to move up and down, and a feeding end 54 is disposed at one side of the placing platform 51, wherein the feeding end 54 includes an eighth cylinder 541 and a pushing block 542 connected to the eighth cylinder 541. The placing platform 51 is provided with a baffle plate 511 to prevent the packaging bag 3 from falling out when the second transmission device transmits the material 4 through the connecting channel 6 to the packaging bag 3.

[0033] After the first photoelectric switch 7 detects that there is material 4 below, the first conveyor belt 211 stops transmitting, and the first conveying device 221 extends to convey the material 4 on the first conveyor belt 211 to the bottom of the compression device 222. One end of the compression device 222 extends to contact and press the material 4 to compress it. The clamping plate 612 in the original tightened state is covered with the packaging bag 3. At this time, the outer surface of the packaging bag 3 contacts the placement table 51. By pressing the control switch 55, the second conveying device 223 is extended, and the seventh cylinder 611 drives the clamping plates 612 at both ends to move so that they contact the upper and lower ends of the inner surface of the packaging bag 3.

[0034] The clamping plates are driven by the seventh cylinder 611, wherein the seventh cylinder 611 is a double-acting double-rod cylinder, so that the clamping plates 612 at both ends move in opposite directions and collide with the upper and lower ends of the inner surface of the packaging bag 3, wherein a channel is formed between the upper and lower sets of clamping plates 612 for the second conveying device 223 to convey the material 4 to the packaging bag 3, and the second conveying device 223 is extended to convey the material 4 to the packaging bag 4 through the compression conveying structure for filling. After the filling is completed, the seventh cylinder 611 drives the clamping plates 612 to move toward each other for tightening, the first conveying device 221, one end of the compression device 222, and the second conveying device 223 shrink to restore the original position, the first conveyor belt 211 resumes transportation, and the first photoelectric switch 7 continues to monitor whether there is material 4. The second cylinder 2221 is a double-acting double-rod cylinder.

[0035] At the same time, the packaging bag 3 filled with the material is placed on the placement table 51, and the fourth cylinders 5211 on both sides extend to drive the folding blocks 5212 to fold the bag opening of the packaging bag 3, and the fifth cylinders 5221 located above and below extend to drive the sealing components 5222 to move toward each other and contact the bag opening of the packaging bag 3 to perform heat sealing. The packaging bag 3 filled with the material 4 is placed on the placement table 51. The sixth cylinders 531 extend to drive the limit blocks 532 on both sides, so that the limit blocks 532 contact the two sides of the packaging bag 3 and prevent the packaging bag 3 from moving. A ninth cylinder 512 is arranged below the placement table 51. In the packaging state, the ninth cylinder 512 extends to keep the placement table 51 in a state corresponding to the connecting channel 6. When the sealing assembly 5222 seals the packaging bag 3 and contracts, the ninth cylinder 512 contracts to lower the placement table 51. A feeding end 54 is arranged on one side of the placement table 51. The eighth cylinder 541 extends to allow the pushing block 542 to push the packaging bag 3 for feeding. After the extension is completed, the eighth cylinder 541 contracts, and the ninth cylinder 512 extends to restore the placement table 51 to a position corresponding to the connecting channel 6. After the heat sealing is completed, the fourth cylinder 5211, the fifth cylinder 5221, and the sixth cylinder 531 all contract to restore their original states and wait for the next signal from the control switch 55.
