[0002] Toilet paper is mainly used for people's daily hygiene and is one of the indispensable types of paper for the people. Toilet paper requires no toxic chemicals, no raw materials that are irritating to the skin, and no mold, virus, or bacterial residues. Toilet paper has the characteristics of strong water absorption, no pathogenic bacteria, soft paper with uniform thickness and no holes, uniform wrinkles, consistent color, and no impurities. However, the existing equipment needs to cut the toilet paper when packaging, and the packaging speed is relatively slow.

[0003] A Chinese patent discloses a toilet paper packaging device for toilet paper production and processing (authorization announcement number CN112373822B).

[0036] The first packaging mechanism includes an extrusion component for squeezing and fixing the inner wall of the toilet paper roll 6, the extrusion component is rotatably connected to the inside of the receiving tray 10, and the side of the extrusion component is provided with a packaging component for initially packaging the toilet paper roll 6, the packaging component is rotatably connected to the side of the extrusion component, and with the mutual cooperation of the extrusion component and the packaging component, the toilet paper roll 6 can be fixed and initially coated, thereby preventing the toilet paper roll 6 from tipping over.

[0037] See also Figure 4 and Figure 6The extrusion assembly includes a first bottom block 26, which is fixedly connected to the inside of the receiving tray 10. A sealing cover 30 is fixedly connected to the top of the first bottom block 26. An I-shaped ring 27 is arranged inside the sealing cover 30. The periphery of the I-shaped ring 27 is meshed with a plurality of conical tooth blocks 28. The conical tooth blocks 28 are located on the outer wall of the I-shaped ring 27, and the portion where the I-shaped ring 27 and the conical tooth blocks 28 are close to each other is provided with an oblique groove that is mutually adapted to the conical tooth blocks 28, so that the periphery of the conical tooth blocks 28 can drive the I-shaped ring 27 to rotate.

[0038] Please refer to 3. Figure 4 and Figure 5 The packaging assembly includes a first servo motor 15, which is fixedly mounted on an inner cavity of one end of the support arm 9 away from the first rotating block 8. A toothed disc 16 and a first supporting plate 18 are arranged on the top of the first servo motor 15. The first supporting plate 18 is fixedly connected to the top of the toothed disc 16. The output shaft of the first servo motor 15 is fixedly connected to a first rotating rod 17. The first rotating rod 17 is fixedly sleeved in the inner cavity of the toothed disc 16 and the first supporting plate 18. The inner cavity of the first rotating rod 17 is threadedly rotatably connected to a threaded screw 19. The threaded screw 19 is fixedly connected to the bottom of the first bottom block 26 away from the first rotating rod 17.

[0039] Specifically, the direction of the thread groove on the outer surface of the threaded screw 19 is opposite to the direction of the thread groove inside the first rotating rod 17. When the first servo motor 15 rotates forward, the threaded screw 19 will always be located on the first rotating rod 17 and will not rotate into the first rotating rod 17. Only when the first servo motor 15 rotates reversely will the threaded screw 19 spirally rotate into the first rotating rod 17.

[0040] See also Figure 4 and Figure 5, a first roller 11 is rotatably mounted on the right end of the first supporting plate 18, a plastic film 13 is sleeved on the periphery of the first roller 11, a top cover 12 is threadedly rotatably sleeved on the top of the first roller 11, and the top cover 12 can limit the plastic film 13, a first connecting rod 14 is threadedly connected to the top of the first roller 11, an end of the first connecting rod 14 away from the first roller 11 is fixedly connected to a first connecting block 22, a second rotating rod 21 is rotatably connected to the bottom of the first connecting block 22, a torsion bar 23 is rotatably connected to the periphery of the second rotating rod 21, a second connecting block 24 is fixedly connected to the outer wall of the torsion bar 23, a slice 25 is fixedly connected to the bottom of the second connecting block 24, a third rotating rod 20 is provided at the right end of the second rotating rod 21, the third rotating rod 20 is rotatably mounted on the bottom end of the first connecting rod 14, a plastic film is sleeved on the periphery of the third rotating rod 20 and the second rotating rod 21 and between the second rotating rod 21 and the slice 25, and the bottom ends of the third rotating rod 20 and the second rotating rod 21 are rotatably connected to the top of the first supporting plate 18;

[0041] Specifically, when the first support plate 18 drives the plastic film 13 to coat the periphery of the toilet paper roll 6, since the outer surface of the plastic film 13 is in contact with the outer walls of the third rotating rod 20 and the second rotating rod 21, and the third rotating rod 20 and the second rotating rod 21 are rotationally connected, when the plastic film 13 rotates a certain number of times driven by the first support plate 18, it will drive the second rotating rod 21 to rotate, and drive the torsion bar 23, the second connecting block 24 and the slice 25 to deflect at a larger angle, so that the slice 25 will rotate to the side of the plastic film 13, and under continuous rotation, the slice 25 will complete the cutting of the plastic film 13, thereby realizing the segmentation of the plastic film 13.

[0042] See also Figure 7 The heat sealing assembly includes an electromagnetic coil 32, which is fixedly mounted on the top of the first rotating block 8 through a support frame 31. An iron core 33 is arranged inside the electromagnetic coil 32, one end of the iron core 33 is fixedly connected to a heat-conducting rod 35, and one end of the heat-conducting rod 35 away from the iron core 33 is fixedly connected to a heat-sealing rod 37, and the heat-sealing rod 37 and the heat-conducting rod 35 are fixedly connected through a heat-conducting clamping plate, and the inner wall of the heat-conducting clamping plate is fixedly connected to the outer wall of the heat-sealing rod 37, and a cylinder 36 is fixedly connected to the inside of the electromagnetic coil 32, and an electric push rod 34 is fixedly mounted on the side of the cylinder 36, and the movable end of the electric push rod 34 is fixedly connected to one end of the iron core 33 away from the heat-conducting rod 35;

[0043] Specifically, the electromagnetic coil 32 is usually wound by a metal wire and has good thermal conductivity. When current passes through the wire, the wire generates heat due to resistance, and the heat will be quickly transferred to the adjacent wire part, so that the temperature of the entire coil gradually increases. When there are other solid media around the electromagnetic coil 32, the heat on the electromagnetic coil 32 is transferred to the iron core 33, and the iron core 33 is then transferred to the heat sealing rod 37 through the heat conducting rod 35 and the heat conducting splint. When a toilet paper roll 6 that has completed the initial coating rotates to the side of the heat sealing rod 37, the heat sealing rod 37 will heat-seal the part of the plastic film 13 wrapped around the outside of the toilet paper roll 6.

[0044] Example 2: Please refer to Figure 8 - Fig.12 Based on the first embodiment, the pushing mechanism includes a second supporting plate 45, the second supporting plate 45 is located at the top of the base 1, the bottom end of the second supporting plate 45 is provided with a first gear 46 and a second gear 58, the first gear 46 and the second gear 58 do not contact each other, the side of the first gear 46 is fixedly connected with a first rotating shaft 48, the top of the first rotating shaft 48 is provided with a second servo motor 4, the output shaft of the second servo motor 4 is fixedly connected to the top of the first rotating shaft 48, the periphery of the first rotating shaft 48 is slidably connected with a guide rod 51, and the second supporting plate 45 is provided with a first gear 46 and a second gear 58. The bottom of the support plate 45 is fixedly connected to the limit frame 59, and the guide rod 51 slides inside the limit frame 59. The guide rod 51 is located between the second support plate 45 and the first gear 46. The end of the guide rod 51 away from the first rotating shaft 48 is fixedly connected to a push plate 52 for pushing the toilet paper roll 6. A sliding groove is provided at one end of the guide rod 51, and the first rotating shaft 48 is located inside the sliding groove. When the guide rod 51 moves, one end of the guide rod 51 drives the push plate 52 to push, and at the same time, the other end of the guide rod 51 will slide around the periphery of the first rotating shaft 48.

[0045] See also Fig.10 , the second gear 58 is symmetrically arranged on the periphery of the first gear 46, and the bottom of the first gear 46 is fixedly connected with an arc-shaped gear rod 47, and the arc-shaped gear rod 47 and the first gear 46 are meshed with each other. Since only a part of the arc-shaped gear rod 47 is provided with tooth grooves, teeth are provided at the end of the guide rod 51 away from the push plate 52. When the first gear 46 drives the arc-shaped gear rod 47 to rotate, the arc-shaped gear rod 47 will also be meshed with the teeth on the periphery of the guide rod 51, thereby driving the guide rod 51 to move. After the first gear 46 rotates again to mesh with the arc-shaped gear rod 47, it can drive the guide rod 51 to rotate in the opposite direction. This cycle is repeated, so that the guide rod 51 drives the push plate 52 to move, thereby realizing the pushing of the toilet paper roll 6. The inner cavities of the arc-shaped gear rod 47 and the second gear 58 are fixedly connected with a fifth rotating rod 49, and the fifth rotating rod 49 is rotatably connected between the base 1 and the second support plate 45. The second support plate 45 is fixedly installed on the top of the base 1 through the first support rod 50;

[0046] Specifically, a reciprocating movement distance or movement time of the guide rod 51 is smaller than a rotation distance or rotation time between two adjacent receiving trays 10, so that before the receiving tray 10 drives the toilet paper roll 6 to rotate to the side of the push plate 52, the push plate 52 has returned to its original state, thereby realizing the reuse of the push plate 52.

[0047] See also Figure 8 and Fig. 9 The second packaging mechanism includes two heat sealing plates 42, which are rotatably connected to the inner wall of the discharge bin 3 through the fourth rotating rod 40. The heat sealing plates 42 are specifically located at the side of the bottom end of the discharge bin 3, thereby increasing the distance between the heat sealing plates 42 and the top of the discharge bin 3, thereby increasing the number of toilet paper rolls 6 that can be loaded. A plurality of synchronous wheels 39 are symmetrically arranged on the periphery of the discharge bin 3, and the plurality of synchronous wheels 39 are sleeved and connected by a synchronous belt 41. A first rotating motor 7 is fixedly installed at the right end of the discharge bin 3.

The remaining synchronous wheels 39 are fixedly connected to both ends of the fourth rotating rod 40.

[0048] Specifically, under the action of the first rotating motor 7, one of the synchronous wheels 39 can be driven to rotate, and the remaining synchronous wheels 39 can be driven to rotate through the synchronous belt 41, and then the fourth rotating rod 40 and the heat sealing plate 42 can be driven to rotate, so that the two heat sealing plates 42 can be turned over synchronously, thereby realizing the heat sealing of the packaging bag 38.

[0049] See also Figure 8 and Fig. 9 The second packaging mechanism also includes a packaging bag 38 arranged in the inner cavity of the discharge bin 3. The packaging bag 38 is arranged in a corrugated shape. The packaging bag 38 is fixed to the top of the inner cavity of the discharge bin 3 by a limiting plug plate, and an inclined groove is opened at the top of the discharge bin 3. A limiting plug plate is arranged inside the inclined groove. At the same time, the top of the packaging bag 38 is located at the top of the discharge bin 3. When the limiting plug plate slides inside the inclined groove, the top of the packaging bag 38 can be fixed. A rotating impeller 43 is arranged on the side of the packaging bag 38. The rotating impeller 43 is rotatably connected to the inside of the discharge bin 3. The side of the rotating impeller 43 is meshed with the corrugated side of the packaging bag 38, which can limit the packaging bag 38.

The other end of the stopper 54 is fixedly connected to a side rod 57 for limiting the position of the toilet paper roll 6. Sliding rods 56 are fixedly connected to both ends of the stopper 54, and the sliding rod 56 is located inside the spring 55. When the stopper 54 and the side rod 57 are pushed by the toilet paper roll 6, the sliding rod 56 can slide on the side of the conveying frame 5, and the maximum sliding distance of the sliding rod 56 is the same as the diameter of the toilet paper roll 6. When a toilet paper roll 6 falls, the stopper 54 and the side rod 57 return to their original state under the action of the spring 55, thereby limiting the position of the next toilet paper roll 6, and the next toilet paper roll 6 will just enter the inside of the next receiving tray 10 when it falls.

[0051] The working principle of the present invention is as follows: when the device is needed, first, the toilet paper roll 6 will move toward the inner cavity of the base 1 under the conveyance of the second roller 53. Before entering the inner cavity of the base 1, when a toilet paper roll 6 moves to the side of the baffle 54 and pushes the baffle 54, the baffle 54 will slide on the side of the conveying frame 5. As the toilet paper roll 6 continues to move, it will gradually break away from the limit of the second roller 53. At this time, the toilet paper roll 6 is just located at the top of the receiving tray 10. When the toilet paper roll 6 is completely free from the limit of the second roller 53, it will fall down. During the process, the extrusion assembly will be wrapped, and at this time, one of the conical tooth blocks 28, which is an electric button block, can be driven. The rotation of the conical tooth block 28 can drive the I-shaped ring 27 to rotate, and drive a plurality of clamping blocks 29 to move spirally around the periphery of the I-shaped ring 27. At the same time, the clamping blocks 29 will also slide on the top of the sealing cover 30, thereby adjusting the contact distance between the plurality of clamping blocks 29 and the inner wall of the toilet paper roll 6, so that one end of the clamping block 29 can squeeze the inner wall of the toilet paper roll 6, thereby fixing the position of the toilet paper roll 6 and preventing the toilet paper roll 6 from tipping over.

[0052] Then, through the first servo motor 15, the rotation of the output shaft of the first servo motor 15 can drive the toothed disc 16, the first rotating rod 17 and the first supporting plate 18 to rotate, and the rotation of the first supporting plate 18 can drive the plastic film 13 to stretch and rotate, thereby realizing the coating of the outer periphery of the toilet paper roll 6; because the first rotating block 8 rotates in the inner cavity of the base 1 under the action of the second rotating motor 2, the plurality of receiving trays 10 and the first packaging mechanism are continuously rotating inside the base 1, and when one receiving tray 10 and the first packaging mechanism rotate and move away from the conveying assembly, the other receiving tray 10 and the first packaging mechanism will be moved to the bottom of the conveying assembly, and the moving distance between two adjacent toilet paper rolls 6 is the same as the moving distance between two adjacent receiving trays 10 and the first packaging mechanism, thereby realizing repeated unloading of toilet paper rolls 6; when one receiving tray 10 and the first packaging mechanism move to the side of the heat sealing assembly, the heat sealing rod 37 will be close to the part of the plastic film 13 wrapped around the outer periphery of the toilet paper roll 6, and then the broken part of the plastic film 13 will be heat sealed, so that the plastic film 13 is completely The toilet paper roll 6 is fully wrapped, thereby realizing the initial coating of the toilet paper roll 6, and under the continued rotation of the first rotating block 8, a receiving tray 10 and a first packaging mechanism are driven to move to the side of the discharge bin 3. At this time, it is necessary to first drive one of the conical gear blocks 28, which is an electric button block, to make the I-shaped ring 27 rotate in the opposite direction, thereby adjusting the contact distance between the clamping block 29 and the inner wall of the toilet paper roll 6, and drive the first servo motor 15, so that the output shaft of the first servo motor 15 rotates in the opposite direction, thereby driving the threaded screw 19 The squeezing assembly is moved downward to lower the height of the squeezing assembly inside the toilet paper roll 6, so that the toilet paper roll 6 can be kept parallel to the top of the first support plate 18, and then the second servo motor 4 is driven to drive the first gear 46 and the arc gear rod 47 to rotate, thereby driving the guide rod 51 to slide, and the push plate 52 can be driven to move during the sliding of the guide rod 51. When the push plate 52 moves to the side of the toilet paper roll 6, it will push the toilet paper roll 6, and then push the toilet paper roll 6 into the inside of the discharge bin 3;

[0053] Before the toilet paper roll 6 enters the discharge bin 3, the bottom of the packaging bag 38 will be folded and sealed under the action of the heat sealing plate 42, and because the packaging bag 38 is arranged in a corrugated shape inside the discharge bin 3, when the toilet paper roll 6 enters the discharge bin 3, it will drive the packaging bag 38 to stretch, and under the action of the rotating impeller 43, the stretching distance of the packaging bag 38 will be limited. When the packaging bag 38 moves down to a certain position, the top of the current packaging bag 38 is heat-sealed again by the heat sealing plate 42, so as to realize the packaging of several toilet paper rolls 6. At this time, the broken part of the packaging bag 38 is located between the two heat sealing plates 42, and the packaging bag 38 is heat-sealed again by the heat sealing plate 42, so as to realize the continuity of packaging, and the toilet paper roll 6 packed by the packaging bag 38 can flow out through the bottom of the inner cavity of the discharge bin 3, so as to realize the effect of automatic unloading.

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.
