[0055] The integrated vacuum packaging machine 5, which combines stacking and bagging, includes a material dispensing device 51, a bagging device 52, and a vacuum sealing device 53. The material dispensing device 51 is connected to the folding device 3, which stacks the folded toilet paper vertically and moves it horizontally to form two conveyor lines. The bagging device 52 has two sets, which are connected to the two conveyor lines respectively, to put the stacked toilet paper into the bag. The vacuum sealing device 53 is located at the subsequent station of the bagging device 52, which removes the air from the bag containing the toilet paper and seals it.

[0056] like Figure 2 As shown, the structure of the feeding device 1 includes a feeding frame 11, a tensioning mechanism 12, a pulling mechanism 13, and a cutting mechanism 14.

[0057] The feeding rack 11 includes multiple toilet paper racks 111 arranged along the direction of toilet paper raw material conveying. Each toilet paper rack 111 is used for toilet paper rolls to be mounted and fed, so that multiple toilet paper rolls can be fed in the same direction at the same time, forming a multi-layer feeding structure with upper and lower distribution.

[0058] The specific number of toilet paper holders 111 can be set according to the specific number of layers of toilet paper. In this embodiment, there are nine toilet paper holders 111 arranged in parallel.

[0059] Each toilet paper holder 111 structure includes an L-shaped holder and a toilet paper roll and a toilet paper raw material discharge channel disposed on the side wall of the L-shaped holder. The toilet paper raw material discharge channel is formed by two raw material guide rollers 1111 distributed vertically.

[0060] The number of channels on the last toilet paper holder 111 is the same as the number of toilet paper holders 111. Each channel on the toilet paper holder 111 corresponds to the toilet paper on each toilet paper holder 111, so that the multi-layer toilet paper raw materials do not come into contact with each other when they are delivered.

[0061] like Figure 3 As shown, the tensioning mechanism 12 includes a tensioning frame 121 connected to the rear side of the last toilet paper holder 111 at the end of the feeding rack 11, a tensioning roller 125 disposed on the tensioning frame 121, and a tensioning drive assembly that drives the tensioning roller 125 to swing.

[0062] The tensioning frame 121 has two symmetrically arranged tensioning arms 122, each with a tensioning plate 123. Multiple tensioning rollers 125 are provided, with each roller's two ends fixed to two tensioning plates 123. The multi-layer toilet paper material fed from the feeding device 1 passes over the multiple tensioning rollers 125 and then through the tensioning guide rollers 128 on the tensioning frame 121 before being discharged. During the conveying of the toilet paper material, the up-and-down swinging of the tensioning rollers 125 achieves the tensioning effect.

[0063] The tensioning drive assembly includes a tensioning cylinder 124, a tensioning connecting rod assembly, and a swing arm connecting rod 129. A tensioning connecting frame 1211 is mounted on the tensioning frame 121. Both ends of the swing arm connecting rod 129 are connected to two tensioning swing arms 122.

When the tensioning cylinder 124 extends, it causes the tensioning swing arm 122 to swing downward. When the tensioning cylinder 124 retracts, it causes the tensioning swing arm 122 to swing upward, thereby causing the tensioning roller 125 to swing up and down, which in turn tensions the multi-layer toilet paper raw material.

[0064] The traction mechanism 13 includes a traction frame 133 connected to the end of the tension frame 121, a traction roller group rotatably mounted on the traction frame 133, and a traction drive assembly that drives the traction roller group to rotate.

[0065] The traction roller assembly includes an upper traction roller 131 and a lower traction roller 132, and a traction channel is formed between the upper traction roller 131 and the lower traction roller 132 for the passage of toilet paper in a multi-layer stacked state.

[0066] The traction drive assembly includes a traction motor and a traction gear set. The traction gear set is connected between the end of the upper traction roller 131 and the rotating shaft of the traction motor. The traction motor drives the upper traction roller 131 and the lower traction roller 132 to rotate in opposite directions, thereby pulling the multi-layered toilet paper that has passed through the traction channel.

[0067] To improve the stability of the traction mechanism, the traction mechanism 13 is equipped with two sets, one in the front and one in the rear.

[0068] The cutting mechanism 14 includes a cutting blade 141 mounted on the pull frame 133 and located behind the pull roller assembly, and a cutting drive assembly that drives the cutting blade 141 to move up and down. The two ends of the cutting blade 141 are connected to slides extending vertically on the pull frame 133 via sliders, allowing it to move up and down. The cutting drive assembly is a cutting cylinder, mounted in the pull frame 133. The cylinder body is fixed inside the pull frame 133, and the piston rod is connected to the slider at the end of the cutting blade 141, driving the cutting blade 141 to move up and down, cutting the conveyed toilet paper.

[0069] like Figure 4 As shown, the trimming device 2 includes a trimming frame 21, a trimming conveyor belt 22, a trimming mechanism 23, and a folding and unloading mechanism 24.

[0070] The edge cutting conveyor 22 is arranged on the edge cutting frame 21, and the feeding end of the edge cutting conveyor 22 is connected with the cutting mechanism 14 to receive the cut sanitary paper in the multi-layered state. The edge cutting conveyor 22 has an edge cutting position and a folding discharging position on the conveying path thereof.

[0071] The edge cutting mechanism 23 is arranged on the edge cutting frame 21 and located on the left and right sides of the edge cutting conveyor 22 and corresponds to the edge cutting position to cut the left and right ends of the sanitary paper to make the size of the sanitary paper meet the preset requirement.

[0072] Each of the edge cutting mechanisms 23 includes an edge cutting mounting plate 231, an edge cutting lifting plate 235, an edge cutting master cylinder 232, an edge cutting cylinder 233 and an edge cutting cutter 234. The edge cutting mounting plate 231 is mounted on the edge cutting frame 21. The edge cutting lifting plate 235 is slidably fitted on the edge cutting mounting plate 231. The cylinder body of the edge cutting master cylinder 232 is mounted on the edge cutting mounting plate 231, and the piston rod is connected with the edge cutting lifting plate 235 to drive the edge cutting lifting plate 235 to move up and down. The cylinder body of the edge cutting cylinder 233 is mounted on the edge cutting lifting plate 235, and the piston rod is connected with the edge cutting cutter 234 to drive the edge cutting cutter 234 to move up and down to cut the left and right edges of the sanitary paper. When the edge cutting master cylinder 232 is contracted, the edge cutting lifting plate 235, the edge cutting cylinder 233 and the edge cutting cutter 234 can be driven to move up as a whole. In this state, even if the edge cutting cylinder 233 is extended, the edge cutting cutter 234 cannot contact the sanitary paper.

[0073] The folding discharging mechanism 24 is arranged on the edge cutting frame 21 and corresponds to the folding discharging position to push the sanitary paper on the folding discharging position out of the edge cutting conveyor 22 and complete the folding.

[0074] The edge cutting conveyor 22 includes an edge cutting conveying roller, a plurality of edge cutting belts wound on the edge cutting conveying roller and an edge cutting driving motor to drive the edge cutting conveying roller to rotate.

The folding discharging mechanism 24 includes a folding discharging push rod motor 241 and a folding discharging push plate 242. The folding discharging push rod motor 241 is arranged on the edge cutting frame 21 and located above the folding discharging position. The folding discharging push plate 242 is arranged on the sliding block of the folding discharging push rod motor 241 and driven by the folding discharging push rod motor 241 to move up and down and located directly above the belt gap 25. When the folding discharging push rod motor 241 drives the folding discharging push plate 242 to move downward, the lower end of the folding discharging push plate 242 can abut against the center line of the sanitary paper to push the sanitary paper on the edge cutting conveyor 22 out of the edge cutting conveyor 22 through the belt gap and complete the first folding of the sanitary paper.

[0075] AsFigure 5 As shown, in the folding device 3 structure, including folding frame 31 and folding mechanism, the folding mechanism is provided on the folding frame 31, including a plurality of folding conveying belt assemblies and a plurality of folding assemblies 33, a plurality of folding conveying channels are formed between the plurality of folding conveying belt assemblies, the plurality of folding conveying channels are sequentially connected, and a folding position 34 is formed between the outlet and the inlet of adjacent folding conveying channels.

[0076] The specific number of folding conveying channels can be set according to the number of folds. In the present embodiment, the toilet paper needs to be folded twice in the folding device 3, so the folding conveying channels have three, which are the first channel 321, the second channel 322 and the third channel 323. A folding position 34 for folding the toilet paper is formed between the outlet of the first channel 321 and the inlet of the second channel 322, and a folding position 34 for folding the toilet paper is also formed between the outlet of the second channel 322 and the inlet of the third channel 323. The inlet of the first channel 321 is upwardly connected to the belt seam at the folding outlet of the edge cutting device 2 to receive the toilet paper after folding.

[0077] The folding assembly 33 corresponds to the folding position 34, and the toilet paper in the previous channel is pushed into the next channel, and the folding is completed. The number of folding assemblies 33 is the same as the number of folding positions 34, which is two groups. Two folding assemblies 33 are respectively located at two folding positions 34, and the toilet paper sent out from the first channel 321 is pushed into the second channel 322, and the toilet paper sent out from the second channel 322 is pushed into the third channel 323, while the folding is completed.

[0078] Each folding conveying belt assembly is composed of a folding roller shaft 3311 mounted on the side wall of the folding frame 31, a folding belt 3312 wound around the folding roller shaft 3311, and a folding motor provided on the folding frame 31 and connected with the folding roller shaft 3311. The arrangement position of the folding roller shaft 3311 in each folding conveying belt assembly is different, so the direction of the folding belt 3312 in different groups is also different, as shown in detail. Figure 5

[0079] ​In this embodiment, the folding conveying belt assembly has eight groups, which are the first conveying belt assembly 331, the second conveying belt assembly 332, the third conveying belt assembly 333, the fourth conveying belt assembly 334, the fifth conveying belt assembly 335, the sixth conveying belt assembly 336, the seventh conveying belt assembly 337 and the eighth conveying belt assembly 338. The part of the folding belt 3312 in the first conveying belt assembly 331 is in contact with the part of the folding belt 3312 in the second conveying belt assembly 332 to form the first channel 321; the part of the folding belt 3312 in the second conveying belt assembly 332 is in contact with the part of the folding belt 3312 in the third conveying belt assembly 333 to form the first channel 3221; the part of the folding belt 3312 in the fourth conveying belt assembly 334 is in contact with the part of the folding belt 3312 in the fifth conveying belt assembly 335 to form the second channel 3222; the part of the folding belt 3312 in the sixth conveying belt assembly 336 is in contact with the part of the folding belt 3312 in the seventh conveying belt assembly 337 to form the third channel 3223; the second channel 322 is formed by the first channel 3221, the second channel 3222 and the third channel 3223 in sequence to increase the conveying distance of the second channel 322, so as to compact the folded toilet paper; the part of the folding belt 3312 in the seventh conveying belt assembly 337 is in contact with the part of the folding belt 3312 in the eighth conveying belt assembly 338 to form the third channel 323.

[0080] The folding support plate 32 is arranged at the outlet of the first channel 321 and the outlet of the second channel 322 and is fixed on the folding frame 31. When the toilet paper is conveyed to the outlet position of the first channel 321 or the second channel 322, the two sides of the toilet paper are respectively in the first channel 321 or the second channel 322 and on the folding support plate 32, and the toilet paper corresponds to the inlet of the next channel, i.e., the second channel 322 or the third channel 323. In this state, the folding assembly 33 can push the toilet paper into the next channel from the middle part of the toilet paper, and the folding operation is completed.

[0081] In order to facilitate the toilet paper to be pushed from the previous channel into the next channel, the inlets of the first channel 321, the second channel 322 and the third channel 323 are all in the shape of a horn, i.e., the two folding belts 3312 corresponding to the inlet position of the channel are in a non-contact state.

[0082] The folding assembly 33 includes a folding cylinder 331 and a folding top plate 332. The folding cylinder 331 is fixed to the folding frame 31 by a mounting rod. The folding top plate 332 is mounted on the slider of the folding cylinder 331, corresponding to the inlet of the second channel 322 or the third channel 323, and perpendicular to the folding support plate 32. The folding cylinder 331 can drive the folding top plate 332 to move towards the inlet of the second channel 321 or the third channel 322, pushing the toilet paper fed from the previous channel into the inlet of the next channel, completing the transfer and folding of the toilet paper.

[0083] The outlets and inlets of adjacent folding conveyor channels are set vertically, which makes it easy for the folding top plate 332 to push the toilet paper into the next channel, while effectively completing the folding operation of the toilet paper.

[0084] like Figure 1 , 6 As shown in Figures 7 and 8, the material distribution device 51 includes a material distribution frame 511, a stacking frame 512, a material distribution lifting drive component, a material distribution pushing drive component, and a material distribution conveyor belt 514.

[0085] The stacking rack 512 is installed on the material distribution rack body 511 via a material distribution lifting drive component, and is connected to the outlet of the toilet paper conveying channel via a conveyor line 4.

[0086] The stacking rack 512 includes a vertical plate 5121 and multiple stacking plates 5122 arranged vertically on the side of the vertical plate 5121 facing the conveyor line 4. The multiple stacking plates 5122 cooperate to form a stacking trough 5123. The inlet of the stacking trough 5123 is connected to the outlet end of the conveyor line 4, so that the folded toilet paper is distributed vertically on the stacking plates 5122 after being fed out of the conveyor line 4. The specific number of stacking plates 5122 can be set according to the number of toilet paper stacks.

[0087] The material dispensing and lifting drive component includes a dispensing slide plate, a dispensing track 513, and a dispensing motor 515. The dispensing track 513 is vertically mounted on the dispensing frame 511. Inside the dispensing track 513, there are rotating shafts at the upper and lower positions, and a dispensing lifting drive belt is wound between the two rotating shafts. The dispensing slide plate is slidably fitted onto the dispensing track 513 and is connected and fixed to the dispensing lifting drive belt. The vertical plate 5121 of the stacking rack 512 is fixed on the dispensing slide plate. The dispensing motor 515 is mounted on the dispensing track 513 and connected to the rotating shafts in the dispensing track 513, driving the dispensing lifting drive belt to move the dispensing slide plate and the stacking rack 512 up and down. This allows the stacking plates 5122 at different heights to connect with the discharge end of the conveyor line 4, so that the toilet paper sent from the conveyor line 4 is placed on the stacking plates 5122 at different heights, achieving the function of stacking.

[0088] The material distribution and pushing drive component is installed on the material distribution frame 511 and corresponds to the stacking frame 512, that is, it is located opposite the stacking frame 512, pushing the toilet paper on the stacking frame 512 to both sides.

[0089] The material dispensing and ejection drive component includes a material dispensing drive cylinder 516 and a material dispensing push plate 517. The material dispensing push plate 517 includes a material dispensing mounting plate connected to the slider of the material dispensing drive cylinder 516 and a material dispensing plate 5171 formed on the material dispensing mounting plate and extending toward the stacking groove 5123. When it is necessary to eject the toilet paper in the stacking groove 5123, the material dispensing motor 515 drives the stacking groove 5123 containing toilet paper to rise and fall to the same height as the material dispensing plate 5171. Then, the material dispensing drive cylinder 516 drives the material dispensing push plate 517 to move to the left and right sides, pushing the toilet paper stacked in the stacking groove 5123 to the left or right at the same time, realizing the feeding and ejection of toilet paper to the left and right sides.

[0090] The material distribution conveyor belt 514 has two belts, which are distributed on both sides of the material distribution frame 511. That is, the two ends of the material distribution frame 511 are fixed on the frame 5143 of the two material distribution conveyor belts 514. The two material distribution conveyor belts 514 receive the toilet paper pushed out from the stacking rack 512.

[0091] The material distribution conveyor belt 514 has a toilet paper trough 5141, which is composed of two limiting baffles set on the material distribution conveyor belt 514 to prevent the toilet paper from moving randomly on the material distribution conveyor belt 514 and to ensure that the toilet paper can be stably conveyed on the material distribution conveyor belt 514.

[0092] like Figure 6 , 8 As shown, the bag feeding device 52 includes a bag feeding mechanism 522, a paper pushing mechanism 523, and a bag opening mechanism 521.

[0093] The bag feeding mechanism 522 includes a bag conveyor belt 5244 disposed outside the material distribution conveyor belt 514, a bag storage box 5241 disposed above the bag conveyor belt 5244, and a bag suction assembly that adsorbs the bags in the bag storage box 5241 onto the bag conveyor belt 5244.

[0094] Two bag storage boxes 5241 are arranged above the starting end of the bag conveyor belt 5244 along the conveying direction of the bag conveyor belt 5244. The bag storage box 5241 is a quadrilateral frame structure with openings at the top and bottom. The bottom inner wall of the frame structure has a supporting inner edge 5242 for supporting the edges of the bags 10, so that the stacked bags 10 can be stored in the bag storage box 5241.

[0095] The suction bag assembly is arranged in the frame 52441 of the bag conveying belt 5244 and corresponds to the two bag storage boxes 5241. The suction bag assembly comprises a suction bag lifting frame which is fitted in the frame 52441 of the bag conveying belt 5244 in a lifting manner, a plurality of first suction nozzles 5243 arranged on the suction bag lifting frame, and a suction bag lifting driving component arranged in the frame of the bag conveying belt 5244 and connected with the suction bag lifting frame. The plurality of first suction nozzles 5243 are divided into two groups and correspond to the two bag storage boxes 5241 respectively.
