[0029] As Figure 2 shown, in the structure of the feeding device 1, it includes a feeding rack 11, a tensioning mechanism 12, a pulling mechanism 13 and a cutting mechanism 14.

[0030] The feeding rack 11 includes a plurality of toilet paper rack bodies 111 arranged along the conveyance direction of the toilet paper raw material. Each toilet paper rack body 111 is used for mounting and feeding toilet paper rolls, so that a plurality of toilet paper rolls can feed in the same direction at the same time, forming an up-and-down distributed multi-layer feeding structure.

[0031] The specific number of the toilet paper rack bodies 111 can be set according to the specific number of layers of the toilet paper. In this embodiment, there are nine toilet paper rack bodies 111 arranged in parallel.

[0032] The structure of each toilet paper rack 111 includes an L-shaped rack, a toilet paper roll roller and a toilet paper raw material discharge channel arranged on the side wall of the L-shaped rack. The toilet paper raw material discharge channel is formed by two raw material guide rollers 1111 distributed vertically and horizontally.

[0033] The number of channels on the last toilet paper rack 111 is the same as the number of toilet paper racks 111. Each channel on this toilet paper rack 111 can correspond to the toilet paper on each toilet paper rack 111, so that multiple layers of toilet paper raw materials do not contact each other when being sent out.

[0034] As Figure 3 shown, the tensioning mechanism 12 includes a tensioning frame body 121 connected to the end of the feeding rack 11, that is, the rear side of the last toilet paper rack 111, a tensioning roller 125 arranged on the tensioning frame body 121, and a tensioning drive assembly for driving the tensioning roller 125 to swing.

[0035] There are two symmetrically arranged tensioning swing arms 122 on the tensioning frame body 121. A tensioning plate 123 is arranged on each tensioning swing arm 122. A plurality of tensioning rollers 125 are arranged. The two ends of each tensioning roller 125 are respectively fixed on two tensioning plates 123. The multiple layers of toilet paper raw materials sent out from the feeding device 1 bypass the plurality of tensioning rollers 125 and then are sent out through the tensioning guide roller 128 on the tensioning frame body 121. When the toilet paper raw materials are being conveyed, the tensioning effect can be achieved by the up-and-down swing of the tensioning rollers 125.

[0036] The tensioning drive assembly includes a tensioning cylinder 124, a tensioning link group and a swing arm link 129. A tensioning connection frame 1211 is built on the tensioning frame body 121; the two ends of the swing arm link 129 are connected to the two tensioning swing arms 122; the tensioning link group includes a tensioning upper link 126 and a tensioning lower link 127.

The cylinder body of the tensioning cylinder 124 is rotatably connected to the front cross beam of the tensioning connection frame 1211, and the piston rod of the tensioning cylinder 124 is rotatably connected to a position near the lower end of the tensioning upper link 126. When the tensioning cylinder 124 extends, it drives the tensioning swing arm 122 to swing downward. When the tensioning cylinder 124 contracts, it drives the tensioning swing arm 122 to swing upward, thereby driving the tensioning roller 125 to swing up and down, playing a tensioning role on the multiple layers of toilet paper raw materials.

[0037] The pulling mechanism 13 includes a pulling frame body 133 connected to the end of the tensioning frame body 121, a pulling roller group rotatably arranged on the pulling frame body 133, and a pulling drive assembly for driving the pulling roller group to rotate.

[0038] The pulling roller group includes an upper pulling roller 131 and a lower pulling roller 132, and a pulling channel for the toilet paper in a multi-layer stacked state to pass through is formed between the upper pulling roller 131 and the lower pulling roller 132.

[0039] The pulling drive assembly includes a pulling motor and a pulling gear set. The pulling gear set is connected between the end of the upper pulling roller 131 and the rotating shaft of the pulling motor. The upper pulling roller 131 and the lower pulling roller 132 are driven by the pulling motor to rotate in opposite directions, so as to pull the multi-layer stacked toilet paper passing through the pulling channel.

[0040] In order to improve the stability of pulling, two sets of front and rear pulling mechanisms 13 are provided.

[0041] The cutting mechanism 14 includes a cutting knife 141 disposed on the pulling frame 133 and behind the pulling roller group, and a cutting drive assembly for driving the cutting knife 141 to move up and down. Both ends of the cutting knife 141 are fitted with sliders in the slideways extending up and down on the pulling frame 133 and can move up and down. The cutting drive assembly is a cutting cylinder disposed in the pulling frame 133. The cylinder body of the cutting cylinder is fixed in the pulling frame 133, and the piston rod is connected to the slider at the end of the cutting knife 141 to drive the cutting knife 141 to move up and down to cut the toilet paper being conveyed.

[0042] As Figure 4 shown, in the structure of the edge trimming device 2, it includes an edge trimming frame 21, an edge trimming conveyor belt 22, an edge trimming mechanism 23 and a folding and discharging mechanism 24.

[0043] The edge trimming conveyor belt 22 is disposed on the edge trimming frame 21. The feeding end of the edge trimming conveyor belt 22 is docked with the cutting mechanism 14 to receive the toilet paper in a multi-layer stacked state after cutting. The edge trimming conveyor belt 22 has an edge trimming position and a folding and discharging position on its conveying path.

[0044] There are two sets of the edge trimming mechanisms 23, which are disposed on the edge trimming frame 21, on the left and right sides of the edge trimming conveyor belt 22 and corresponding to the edge trimming positions, to trim the left and right ends of the toilet paper so that the size of the toilet paper meets the preset requirements.

[0045] Each edge trimming mechanism 23 includes an edge trimming mounting plate 231, an edge trimming lifting plate 235, an edge trimming master cylinder 232, an edge trimming cylinder 233, and an edge trimming cutter 234. The edge trimming mounting plate 231 is mounted on the edge trimming frame 21; the edge trimming lifting plate 235 is slidably engaged with the edge trimming mounting plate 231 up and down; the cylinder body of the edge trimming master cylinder 232 is mounted on the edge trimming mounting plate 231, and the piston rod is connected to the edge trimming lifting plate 235 to drive the edge trimming lifting plate 235 to move up and down; the cylinder body of the edge trimming cylinder 233 is mounted on the edge trimming lifting plate 235, and the piston rod is connected to the edge trimming cutter 234 to drive the edge trimming cutter 234 to move up and down, which plays a role in trimming the left and right edges of the toilet paper. After the edge trimming master cylinder 232 contracts, it can drive the edge trimming lifting plate 235, the edge trimming cylinder 233, and the edge trimming cutter 234 to move up as a whole. In this state, even if the edge trimming cylinder 233 extends, the edge trimming cutter 234 cannot contact the toilet paper.

[0046] The folding and discharging mechanism 24 is arranged on the edge trimming frame 21, corresponding to the folding and discharging position, to push the toilet paper at the folding and discharging position out of the edge trimming conveyor belt 22 and complete the folding.

[0047] The edge trimming conveyor belt 22 includes edge trimming conveyor rollers, multiple edge trimming belts wound around the edge trimming conveyor rollers, and an edge trimming drive motor that drives the edge trimming conveyor rollers to rotate. The multiple edge trimming belts are arranged at intervals and have belt seams, and there is such a belt seam 25 at the folding and discharging position. The folding and discharging mechanism 24 includes a folding and discharging push rod motor 241 and a folding and discharging push plate 242. The folding and discharging push rod motor 241 is arranged on the edge trimming frame 21 and is located above the folding and discharging position. The folding and discharging push plate 242 is arranged on the slider of the folding and discharging push rod motor 241 and is driven by the folding and discharging push rod motor 241 to move up and down and is located directly above the belt seam 25. When the folding and discharging push rod motor 241 drives the folding and discharging push plate 242 to move downward, the lower end of the folding and discharging push plate 242 can press against the center line position of the toilet paper, and push the toilet paper on the edge trimming conveyor belt 22 downward through the belt seam out of the edge trimming conveyor belt 22, and at the same time complete the first folding effect of the toilet paper.

[0048] As Figure 5 shown, in the folding device 3 structure, it includes a folding frame 31 and a folding mechanism. The folding mechanism is arranged on the folding frame 31 and includes multiple groups of folding conveyor belt assemblies and multiple groups of folding assemblies 33. Multiple folding conveyor channels are formed between the multiple groups of folding conveyor belt assemblies. The multiple folding conveyor channels are connected in sequence, and a folding position 34 is formed between the outlet and the inlet of adjacent folding conveyor channels.

[0049] The specific number of folding and conveying channels can be set based on the number of folds required. In this embodiment, the toilet paper needs to be folded twice in the folding device 3, so there are three folding and conveying channels: a first channel 321, a second channel 322, and a third channel 323. A folding position 34 for folding the toilet paper in half is formed between the outlet of the first channel 321 and the inlet of the second channel 322. A folding position 34 for folding the toilet paper in half 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 faces upward and mates with the belt seam at the folding outlet of the trimming device 2 to receive the folded toilet paper.

[0050] The folding components 33 correspond to the folding positions 34 and push the toilet paper from the previous channel into the next channel, completing the fold. There are two sets of folding components 33, the same number as the folding positions 34. The two sets of folding components 33 are located at the two folding positions 34, pushing the toilet paper fed from the first channel 321 into the second channel 322 and from the second channel 322 into the third channel 323, completing the fold simultaneously.

[0051] Each folding conveyor belt assembly consists of a folding roller 3311 mounted on the side wall of the folding frame 31, a folding belt 3312 wound around the folding roller 3311, and a folding motor mounted on the folding frame 31 and connected to the folding roller 3311. The folding roller 3311 in each folding conveyor belt assembly is arranged in a different position, so the direction of the folding belt 3312 in different groups is also different. Figure 5 shown.

[0052] In this embodiment, there are 8 sets of folding conveyor belt assemblies, namely the first conveyor belt assembly 331, the second conveyor belt assembly 332, the third conveyor belt assembly 333, the fourth conveyor belt assembly 334, the fifth conveyor belt assembly 335, the sixth conveyor belt assembly 336, the seventh conveyor belt assembly 337, and the eighth conveyor belt assembly 338. Part of the folding belt 3312 in the first conveyor belt assembly 331 is attached to part of the folding belt 3312 in the second conveyor belt assembly 332 to form the first channel 321; part of the folding belt 3312 in the second conveyor belt assembly 332 is attached to part of the folding belt 3312 in the third conveyor belt assembly 333 to form channel one 3221, part of the folding belt 3312 in the fourth conveyor belt assembly 334 is attached to part of the folding belt 3312 in the fifth conveyor belt assembly 335 to form channel two 3222, part of the folding belt 3312 in the sixth conveyor belt assembly 336 is attached to part of the folding belt 3312 in the seventh conveyor belt assembly 337 to form channel three 3223, and the second channel 322 is formed by the sequential connection of channel one 3221, channel two 3222, and channel three 3223 to increase the conveying distance of the second channel 322 and achieve a compaction effect on the folded toilet paper; part of the folding belt 3312 in the seventh conveyor belt assembly 337 is attached to part of the folding belt 3312 in the eighth conveyor belt assembly 338 to form the third channel 323.

[0053] Folding support plates 32 are provided at the exits of both the first channel 321 and the second channel 322, and the folding support plates 32 are fixed to the folding frame 31. When the toilet paper is conveyed to the exit position of the first channel 321 or the second channel 322, both sides of the toilet paper are respectively located on the folding support plates 32 in the first channel 321 or the second channel 322, and at the same time, the toilet paper corresponds to the inlet of the next channel, that is, the second channel 322 or the third channel 323. In this state, the folding assembly 33 can push against the middle part of the toilet paper and push the toilet paper into the next channel while completing the folding operation.

[0054] To facilitate the pushing of the toilet paper 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 a flared structure, that is, the two folding belts 3312 forming the channel are in a non-attached state at the position corresponding to the channel inlet.

[0055] The folding assembly 33 includes a folding cylinder 331 and a folding top plate 332. The folding cylinder 331 is fixed on the folding frame 31 through 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 is 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, push the toilet paper sent from the previous channel into the inlet of the next channel, and complete the transfer and folding of the toilet paper.

[0056] The outlets and inlets of adjacent folding transfer channels are vertically arranged, which is convenient for the folding top plate 332 to push the toilet paper into the next channel and effectively complete the folding operation of the toilet paper.

[0057] As Figure 1 、 6 、7, and 8 show, in the structure of the material distribution device 51, it includes a material distribution frame body 511, a stacking frame 512, a material distribution lifting drive component, a material distribution pushing drive component, and a material distribution conveyor belt 514.

[0058] The stacking frame 512 is installed on the material distribution frame body 511 through a material distribution lifting drive component and is connected to the discharge port of the toilet paper transfer channel through a conveyor line 4.

[0059] The stacking frame 512 includes a vertical plate 5121 and a plurality of stacking plates 5122 arranged vertically on one side of the vertical plate 5121 facing the conveyor line 4. The plurality of stacking plates 5122 cooperate to form a stacking groove 5123. The inlet of the stacking groove 5123 is connected to the discharge end of the conveyor line 4, and the folded toilet paper is placed on the stacking plates 5122 in a vertical distribution after being sent out of the conveyor line 4. The specific number of the stacking plates 5122 can be set according to the number of toilet paper stacks.

[0060] The material distribution lifting drive component includes a material distribution sliding plate, a material distribution track 513, and a material distribution motor 515. The material distribution track 513 is installed vertically on the material distribution frame body 511. There are rotating shafts at the upper and lower positions inside the material distribution track 513, and a material distribution lifting drive belt is wound between the upper and lower rotating shafts. The material distribution sliding plate is slidably fitted on the material distribution track 513 and is fixedly connected to the material distribution lifting drive belt. The vertical plate 5121 in the stacking frame 512 is fixed on the material distribution sliding plate. The material distribution motor 515 is installed on the material distribution track 513, and the material distribution motor 515 is connected to the rotating shaft in the material distribution track 513 to drive the material distribution lifting drive belt to drive, thereby driving the material distribution sliding plate and the stacking frame 512 to move up and down, enabling the stacking plates 5122 at different heights to be docked with the discharge end of the conveyor line 4, and the toilet paper sent out from the conveyor line 4 to be placed on the stacking plates 5122 at different heights to achieve the function of vertical stacking.

[0061] The material distributing and pushing driving component is installed on the material distributing frame body 511, corresponding to the stacking frame 512, i.e., located opposite the stacking frame 512, and pushes the toilet paper on the stacking frame 512 to both sides.

[0062] The material distributing and pushing driving component includes a material distributing driving cylinder 516 and a material distributing push plate 517. The material distributing push plate 517 includes a material distributing mounting plate connected to the slider of the material distributing driving cylinder 516 and a material distributing plate 5171 formed on the material distributing mounting plate and extending towards the stacking groove 5123. When it is necessary to push out the toilet paper in the stacking groove 5123, the material distributing motor 515 drives the stacking groove 5123 filled with toilet paper to rise and fall to the same height as the material distributing plate 5171, and then the material distributing driving cylinder 516 drives the material distributing push plate 517 to move towards the left and right sides, pushing the toilet paper stacked in the stacking groove 5123 to the left or right at the same time, so as to realize the feeding of the toilet paper to the left and right sides.

[0063] There are two material distributing conveyor belts 514, which are distributed on both sides of the material distributing frame body 511, i.e., the two ends of the material distributing frame body 511 are fixed on the frame bodies 5143 of the two material distributing conveyor belts 514, and the two material distributing conveyor belts 514 receive the toilet paper pushed out from the stacking frame 512.

[0064] There is a toilet paper groove 5141 on the material distributing conveyor belt 514, which is composed of two limit baffles arranged on the material distributing conveyor belt 514, preventing the toilet paper from moving randomly on the material distributing conveyor belt 514 and enabling the toilet paper to be stably conveyed on the material distributing conveyor belt 514.

[0065] As Figure 6 、 8 shown, in the structure of the bagging device 52, it includes a bag feeding mechanism 522, a paper pushing mechanism 523 and a bag mouth opening mechanism 521.

[0066] The bag feeding mechanism 522 includes a bag conveyor belt 5244 arranged outside the material distributing conveyor belt 514, a bag storage box 5241 arranged above the bag conveyor belt 5244, and a bag sucking component for sucking the bags in the bag storage box 5241 onto the bag conveyor belt 5244.

[0067] There are two bag storage boxes 5241, which are arranged above the starting end position 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 upper and lower openings, and there is a supporting inner edge 5242 on the inner side wall of the bottom of the frame structure for supporting the edge position of the bag 10, so that the stacked bags 10 are stored in the bag storage box 5241.

[0068] The bag suction assembly is arranged in the frame 52441 of the bag conveyor 5244 and corresponds to two bag storage boxes 5241 at the same time. The bag suction assembly includes a bag suction lifting frame that is liftably fitted in the frame 52441 of the bag conveyor 5244, a plurality of first suction nozzles 5243 arranged on the bag suction lifting frame, and a bag suction lifting drive component arranged in the frame of the bag conveyor 5244 and connected to the bag suction lifting frame at the same time. The plurality of first suction nozzles 5243 are divided into two groups, corresponding to the two bag storage boxes 5241 respectively. After the bag suction lifting drive component drives the bag suction lifting frame and the first suction nozzles 5243 to rise, the two groups of first suction nozzles 5243 can pass through the conveying surface of the bag conveyor 5244 and contact the bags at the bottom of the two bag storage boxes 5241 respectively, adsorb the bags at the bottom, and then the bag suction lifting drive component drives the first suction nozzles 5243 to move downwards, sucking out the corresponding bags from the bottom of the bag storage box 5241 to the bag conveyor 5244, so that the bags move onto the bag conveyor 5244 and are conveyed along with the bag conveyor 5244.

[0069] The plurality of first suction nozzles 5243 are connected to a vacuum pump through pipelines. When the bags move from the bag storage box 5241 to the bag conveyor 5244, the vacuum pump stops working, so that the first suction nozzles 5243 have no adsorption force on the bags, and the bags can stably fall onto the bag conveyor 5244.

[0070] There is a bag loading position on the conveying path of the bag conveyor 5244. The bag mouth opening mechanism 521 is arranged on the frame 52441 of the bag conveyor 5244, corresponding to the bag loading position, and can open the bag mouth of the bag at the bag loading position.

[0071] The bag mouth opening mechanism 521 includes an upper adsorption component and a lower adsorption component arranged on the frame of the bag conveyor 5244 and located on the upper and lower sides of the bag loading position. The upper adsorption component and the lower adsorption component can respectively adsorb the upper bag wall 101 and the lower bag wall of the bag, drive the upper bag wall 101 to move relative to the lower bag wall, and open the bag mouth of the bag.

[0072] The upper adsorption component and the lower adsorption component have the same structure, both including a bag mouth opening frame body 5211, a bag mouth opening cylinder 5212 arranged on the bag mouth opening frame body 5211, a bag mouth opening lifting frame 5214 arranged on the slide plate of the bag mouth opening cylinder 5212, and a plurality of second suction nozzles 5213 arranged on the bag mouth opening lifting frame 5214. The upper adsorption component and the lower adsorption component are symmetrically arranged on the upper and lower sides of the bagging position. The second suction nozzles 5213 in the upper adsorption component are located above the bag body conveyor belt 5244, adsorbing the upper bag wall 101 of the bag mouth of the bag body. The second suction nozzles 5213 in the lower adsorption component are located in the frame body of the bag body conveyor belt 5244, below the bag body conveyor belt 5244, and adsorb the lower bag wall of the bag mouth of the bag body. During the process of opening the bag body, the second suction nozzles 5213 in the lower adsorption component move upward driven by the bag mouth opening cylinder, pass through the bag body conveyor belt 5244 and then adsorb the lower bag wall of the bag mouth of the bag body at the bagging position. The second suction nozzles 5213 in the upper adsorption component move downward driven by the bag mouth opening cylinder and adsorb the upper bag wall 101 of the bag mouth of the bag body at the bagging position. The bag mouth opening cylinder in the upper adsorption component drives the second suction nozzles 5213 to move upward, and the bag mouth of the bag body at the bagging position can be opened. The second suction nozzles 5213 are also connected to a vacuum pump through pipelines.

[0073] The plurality of second suction nozzles 5213 are divided into two groups and can simultaneously perform the bag mouth opening operation on two bag bodies at the bagging position.

[0074] The paper pushing mechanism 523 is arranged at the bag mouth opening mechanism 521 and pushes the toilet paper corresponding to the bagging position on the material distribution conveyor belt 514 into the bag body at the bagging position.

[0075] The paper pushing mechanism 523 includes two paper pushing cylinders 5231 arranged on the frame body 5143 of the material distribution conveyor belt 514 and a paper pushing rod 5232 connected to the sliders of the two paper pushing cylinders 5231. The paper pushing rod 5232 is provided with a paper pushing plate 5233 that can correspond to the toilet paper groove 5141. The two paper pushing cylinders 5231 are arranged along the conveying direction of the material distribution conveyor belt 514, driving the paper pushing rod 5232 to move in a direction perpendicular to the material distribution conveyor belt 514, pushing the toilet paper in the toilet paper groove 5141 towards the bagging position side, and pushing the toilet paper into the bag body at the bagging position that is in the bag mouth opening state.

[0076] As Figure 9 shown, the bagging device 52 further includes a bag mouth expanding mechanism, and the bag mouth expanding mechanism includes an expanding plate 5251 and an expanding driving component.

[0077] There are two spreading plates 5251, which are symmetrically rotatably arranged at the position corresponding to the bagging position of the bag conveyor 5244, and have a spreading position and a retracting position. When the two spreading plates 5251 are in the spreading position, the outer ends of the spreading plates 5251 are located inside the bag and abut against the inner walls on both sides of the bag mouth. When in the retracting position, the outer ends of the spreading plates 5251 are located outside the bag. The spreading driving assembly is installed in the frame of the bag conveyor 5244 and is connected to the two spreading plates 5251, driving the two spreading plates 5251 to rotate between the spreading position and the retracting position. After the upper suction assembly and the lower suction assembly open the bag mouth of the bag, the spreading driving assembly drives the spreading plates 5251 to rotate to the spreading position, so that the outer ends of the two spreading plates 5251 turn into the bag and abut against the inner walls on both sides of the bag mouth of the bag, making the bag mouth of the bag open in a quadrilateral state, which is convenient for the toilet paper on the dispensing conveyor 514 to be pushed into the bag.

[0078] The spreading plate 5251 is installed on the frame of the bag conveyor 5244 through a rotating shaft 5252, corresponding to one side of the bag mouth of the bag. The spreading driving assembly includes a spreading driving motor and a spreading gear set. The spreading driving motor and the spreading gear set are both arranged in the frame of the bag conveyor 5244. The spreading driving motor is connected to the rotating shafts of the two spreading plates 5251 through the spreading gear set, driving the two spreading plates 5251 to rotate in the opposite direction and rotate and switch between the spreading position and the retracting position.

[0079] As Figure 8 , 10 shown, in the structure of the vacuum sealing device 53, it includes a pressing plate mechanism, an air extraction mechanism 534 and a sealing mechanism 533.

[0080] The pressing plate mechanism is arranged above the bag conveyor 5244 and can compact the toilet paper in the bag. The pressing plate mechanism includes a moving pressing component 531 and a fixed pressing component 532.

[0081] The moving pressing component 531 includes a moving frame 5315 fitted on the side of the bag conveyor 5244, a sliding cylinder 5311 driving the moving frame 5315 to move, and a moving pressing group arranged on the moving frame 5315, and the moving pressing group corresponds to the rear half part of the bag.

[0082] The sliding cylinder 5311 is arranged on the frame 52441 of the bag conveyor 5244, on the side of the bag conveyor 5244, and extends along the conveying direction of the bag conveyor 5244; the moving frame 5315 is arranged on the slider of the sliding cylinder 5311 and is driven by the sliding cylinder 5311 to move, that is, driving the moving frame 5315 to move between the bagging position and the sealing position of the bag conveyor 5244.

[0083] The moving downward pressing group includes a first downward pressing cylinder 5312, a first pressing plate 5314, and a first pressing block 5313. The first downward pressing cylinder 5312 is arranged in an inverted state on the moving frame 5315; the first pressing plate 5314 is arranged on the piston rod of the first downward pressing cylinder 5312 and is driven by the first downward pressing cylinder 5312 to move up and down. The first pressing block 5313 is arranged on the lower surface of the first pressing plate 5314 and corresponds to the rear half part of the bag body. After the toilet paper is loaded into the bag body, the first downward pressing cylinder 5312 drives the first pressing block 5313 to move downward, so that the first pressing block 5313 presses tightly on the rear half part of the bag body. At the same time, the sliding cylinder 5311 drives the first pressing block 5313 to move synchronously with the bag body containing the toilet paper on the bag body conveyor belt 5244 to the sealing position. During this process, the first pressing block 5313 presses downward on the bag body containing the toilet paper and moves synchronously with the bag body, which can ensure that the position of the bag body will not move randomly. At the same time, since it presses downward on the rear half part of the bag body, the bag mouth of the bag body can also be opened, facilitating the air extraction operation of the air extraction mechanism 534.

[0084] There are multiple first pressing blocks 5313. After the first pressing plate 5314 moves downward, the multiple first pressing blocks 5313 can press downward on two bag bodies simultaneously.

[0085] In order to improve the stability of the up and down movement of the first pressing plate 5314, a guiding component is arranged between the moving frame 5315 and the first pressing plate 5314. The guiding component includes a guiding rod arranged on the first pressing plate 5314 and a guiding sleeve arranged on the moving frame 5315 for the upper end of the guiding rod to pass through.

[0086] The fixed downward pressing component 532 includes a fixed frame 5322 arranged on the side of the bag body conveyor belt 5244 and a fixed downward pressing group arranged on the fixed frame 5322. The fixed downward pressing group corresponds to the front half part of the bag body.

[0087] The fixed frame 5322 is arranged on the frame of the bag body conveyor belt 5244 at the position corresponding to the sealing position of the bag body conveyor belt 5244. The fixed downward pressing group includes a second downward pressing cylinder 5321, a second pressing plate 5323, and a second pressing block 5324. The second downward pressing cylinder 5321 is fixed on the fixed frame 5322 in an inverted state. The second pressing plate 5323 is fixed on the piston rod of the second downward pressing cylinder 5321. There are multiple second pressing blocks 5324, which are fixed on the lower surface of the second pressing plate 5323 and correspond to the front half part of the bag body at the sealing position. The second downward pressing cylinder 5321 drives the second pressing block 5324 to move downward, so that the second pressing block 5324 presses tightly on the front half part of the bag body, cooperating with the first pressing block 5313 to compact the toilet paper in the bag body, facilitating the air extraction and sealing operations.

[0088] The air extraction mechanism 534 includes an air extraction displacement driving component and an air extraction component arranged on the side of the bag conveyor belt 5244. The air extraction displacement driving component is connected to the air extraction component and drives the air extraction end of the air extraction component to enter and exit the bag.

[0089] The air extraction displacement driving component is an air extraction displacement driving cylinder 5343, which is fixed on the frame of the material distribution conveyor belt 514, and the piston rod can extend or contract towards the bag conveyor belt 5244. The air extraction component includes an air extraction pipe 5341 and an air extraction sliding plate 5342. The air extraction pipe 5341 is arranged on the air extraction sliding plate 5342 and is connected to an air extraction pump through a pipeline. The air extraction sliding plate 5342 is slidably arranged on the frame of the material distribution conveyor belt 514 and is connected to the piston rod of the air extraction displacement driving cylinder 5343. The air extraction displacement driving cylinder 5343 drives the air extraction pipe 5341 to move towards or away from the sealing position of the bag conveyor belt 5244. When the air extraction displacement driving cylinder 5343 drives the air extraction pipe 5341 to move towards the sealing position, the air extraction end of the air extraction pipe 5341 can extend into the bag filled with toilet paper at the sealing position to extract the air in the bag. After the air is extracted, the air extraction displacement driving cylinder 5343 drives the air extraction pipe 5341 to separate from the bag. It should be noted that the second pressing plate 5323 presses down on the front half of the bag after the air extraction pipe 5341 extends into the bag.

[0090] The sealing mechanism 533 is arranged on the side of the bag conveyor belt 5244 to seal the bag mouth of the bag after air extraction.

[0091] The sealing mechanism 533 includes a sealing cylinder 5331, a sealing pressing plate 5333 and a hot knife 5332. The sealing cylinder 5331 is arranged in an inverted state on the fixed frame 5322 and is located outside the second pressing cylinder 5321. The sealing pressing plate 5333 is installed on the piston rod of the sealing cylinder 5331, and the hot knife 5332 is arranged on the sealing pressing plate 5333. When the bag filled with toilet paper is evacuated, the sealing cylinder 5331 drives the sealing pressing plate 5333 and the hot knife 5332 to move downward, so that the hot knife 5332 contacts the bag mouth positions of the two bags at the sealing position at the same time, completing the simultaneous sealing operation of the two bags.

[0092] After the bag is sealed, it is conveyed out of the bag conveyor belt 5244.

[0093] During specific operation, a plurality of toilet paper rolls are erected on the feeding device 1 to realize the multi-layer feeding function of the feeding device 1, and at the same time, tensioning, pulling and cutting operations are performed on the multi-layer toilet paper raw materials; The multi-layer toilet paper in the stacked state after being cut enters the trimming conveyor belt 22 of the trimming device 2, and the excess edge material of the toilet paper is trimmed by the trimming mechanism 23 at the trimming position. After trimming, it is conveyed to the folding and discharging position, ejected from the trimming conveyor belt 22, and the first folding is completed simultaneously. The folding device 3 receives the toilet paper that has been folded for the first time, and then continues to perform two folding operations on the toilet paper and sends it out. After passing through the conveyor line 4, the toilet paper is divided into two upper and lower stacks and placed on the stacking rack 512. It is alternately pushed to the sorting conveyor belts 514 on both sides by the sorting and pushing drive components, and the bagging, vacuum pumping, and sealing operations are performed on the toilet paper synchronously using two lines. After receiving the toilet paper in the stacked state, the sorting conveyor belt 514 conveys it. At the same time, the bag body conveyor belt 5244 conveys the empty bags. When the empty bag is conveyed to the bagging position, the bag mouth of the bag body is opened by the bag mouth opening mechanism 521. At this time, the toilet paper corresponding to the bagging position on the sorting conveyor belt 514 is pushed into the bag body at the bagging position by the paper pushing mechanism 523. The first pressing block 5313 presses on the bag body containing the toilet paper and moves to the sealing position synchronously with the bag body. The air extraction displacement driving cylinder 5343 drives the air extraction end of the air extraction pipe 5341 to extend into the bag body. Then, the second pressing block 5324 presses down on the front half part of the bag body, and the air extraction pipe 5341 performs an air extraction operation to evacuate the air in the bag body. When the air is exhausted, the sealing cylinder 5331 drives the hot knife 5332 to move down and contact the bag mouth part of the bag body. At the same time, the air extraction pipe 5341 withdraws from the bag mouth, and the bag mouth is heat-sealed by the hot knife 5332 to complete the packaging, and finally it is sent out from the bag body conveyor belt 5244.

[0094] In the above process, the full-automatic packaging function of the toilet paper can be realized, significantly improving the packaging efficiency and stability of the toilet paper, and at the same time reducing the labor cost.

[0095] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
