[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 7As shown, the present invention proposes a paper towel stacking device, comprising a workbench 1, a feeding mechanism 8 is installed on one side of the workbench 1, the workbench 1 comprises a panel 11, side panels 12 are installed on both sides of the panel 11, a paper placing mechanism 2 is installed between the two side panels 12, a top panel 41 is installed on the top of the side panel 12, a paper separation mechanism 4 is installed on one side of the top panel 41, at least one hooking mechanism 7 is installed on the other side of the top panel 41, a vertical hook mechanism 3 is installed on one side of the side panel 12, a push rod seat plate 61 is installed between the two side panels 12, at least one horizontal hook mechanism 6 is installed on the push rod seat plate 61, a material pushing mechanism 5 is installed on one side of the bottom surface of the panel 11, at least one rotating mechanism 9 is installed on the other side of the bottom surface of the panel 11, a lifting mechanism 10 is arranged outside one side of the rotating mechanism 9, and the lifting mechanism 10 is installed at the bottom of the panel 11. The paper towel stacking device designs an integrated workflow, and realizes efficient and accurate stacking of paper towels through the coordinated work of a series of mechanisms. The specific working process is as follows: the unstacked paper towels are first sent to the paper separation mechanism 4 through the conveying device. The paper separation mechanism 4 separates the continuous paper towels into single sheets or a set number of small piles, and guides them into the paper placing mechanism 2. The pushing mechanism 5 is responsible for pushing the paper towels in the paper placing mechanism 2 to the horizontal hook mechanism 6. In this process, the paper towels are preliminarily arranged and sorted. The paper towels passing through the horizontal hook mechanism 6 are then pushed to the rotating mechanism 9, which can rotate the paper towels as needed to ensure that they are in the correct direction to adapt to the subsequent processing steps. The vertical hook mechanism 3 further pushes the rotated paper towels to the lifting mechanism 10. The lifting mechanism 10 lifts the paper towels so that the paper towels can be smoothly received by the hooking mechanism 7 and finally pushed to the feeding mechanism 8. Finally, the feeding mechanism 8 conveys the already folded paper towels to prepare for the next step of processing or packaging. By introducing multiple automated mechanisms, the automation level of the paper towel stacking process is greatly improved, the need for manual intervention is reduced, and production efficiency is improved.

[0032] The paper feeding mechanism 2 includes a flip shaft 26, and at least one paper feeding fixed plate 28 is installed on the side wall of the flip shaft 26. Both ends of the flip shaft 26 are installed with paper feeding servo fixed seats 27, and the paper feeding servo fixed seat 27 is rotatably connected to the flip shaft 26. A paper feeding servo 29 is installed on one side of the paper feeding servo fixed seat 27, and the rotor of the paper feeding servo 29 is fixedly connected to one end of the flip shaft 26. A lower side plate 22 is clamped on one side of the paper feeding servo fixed seat 27, and the lower side plate 22 is slidably connected to the paper feeding servo fixed seat 27. A first push-pull member 25 is installed on one side of the lower side plate 22, and a push-pull member support 210 is installed on one end of the first push-pull member 25. One end of the push-pull member support 210 is The paper placing servo fixing seat 27 is fixedly connected, and a first adjusting screw rod 23 is sleeved inside the lower side plate 22, and the first adjusting screw rod 23 is threadedly connected to the lower side plate 22, and the lower side plate 22 is slidably connected to the panel 11, and a lower side plate fixing block 24 is arranged on the outside of one side of the lower side plate 22, and the lower side plate fixing block 24 is sleeved outside the first adjusting screw rod 23, and the first adjusting screw rod 23 is rotatably connected to the lower side plate fixing block 24, and the lower side plate fixing block 24 is fixedly connected to the side plate 12, and a lower side plate adjusting slider 21 is installed on one side of the lower side plate 22, and a guide rail engaged with the lower side plate adjusting slider 21 is installed on one side of the side plate 12, and the guide rail is slidably connected to the lower side plate adjusting slider 21. The paper feed fixing plate 28 is installed on the side wall of the flip shaft 26, and is used to receive the paper towels transmitted from the paper separation mechanism 4. When the paper towels need to be flipped to the surface of the panel 11, the paper placing servo 29 is driven, and the rotor of the motor is fixedly connected to one end of the flip shaft 26. After starting the motor, the flip shaft 26 rotates accordingly, driving the paper feed fixing plate 28 to rotate together, thereby flipping the paper towels in the paper feed fixing plate 28 to the surface of the panel 11, so that the pushing mechanism 5 can smoothly push the paper towels. By controlling the telescopic action of the first push-pull member 25, the paper placing servo fixing seat 27 can be driven to rise and fall, and then the height of the flip shaft 26 and the paper feed fixing plate 28 thereon can be adjusted to ensure that the paper towels can be processed at the correct height. The lower side plate 22 is sleeved with a first adjusting screw 23, and the two are connected by a thread. When the first adjusting screw 23 is rotated, the lower side plate 22 can be moved along the guide rail direction by the action of the thread. As the lower side plate 22 moves, the lower side plate 22 will drive the flip shaft 26 to move together through the paper placing servo fixing seat 27, thereby changing the position of the paper feeding fixing plate 28 relative to the paper separation mechanism 4 to ensure that it can adapt to paper towels of different specifications. By adjusting the position and height of the paper feeding fixing plate 28, the paper placing mechanism 2 can automatically adapt to paper towels of different thicknesses and sizes. A lower side plate adjustment slider 21 is installed on one side of the lower side plate 22, and a guide rail is provided on one side of the side plate 12 to be clamped therewith. The sliding connection between the two not only provides additional stability, but also ensures that the lower side plate 22 moves in a straight line along the predetermined track to avoid deviation or tilting.

[0033] Furthermore, as a preferred embodiment of the present invention but not a limitation, the paper separation mechanism 4 includes a second adjusting screw rod 42, the second adjusting screw rod 42 is sleeved in the top panel 41, the top panel 41 is threadedly connected to the second adjusting screw rod 42, one end of the second adjusting screw rod 42 is rotatably connected to a movable plate 44, the movable plate 44 is equipped with at least one swing shaft 43, the swing shaft 43 is sleeved in the top panel 41, the swing shaft 43 is slidably connected to the top panel 41, the bottom of the movable plate 44 is hinged with a third push-pull member 410, one end of the third push-pull member 410 is hinged with a second swing arm 411, and a lower shaft 415 is installed on one side of the second swing arm 411. 415 is installed with a paddle 412, the lower shaft 415 is provided with a seat bearing 413 on its outer sleeve, the seat bearing 413 is rotatably connected to the lower shaft 415, the seat bearing 413 is fixedly connected to the movable plate 44, the bottom of the top panel 41 is hinged with a second push-pull member 46, one end of the second push-pull member 46 is hinged with a first swing arm 48, a rotating shaft 414 is installed on one side of the first swing arm 48, at least one upper shift rod 49 is installed on the side wall of the rotating shaft 414, the rotating shaft 414 is provided with a bearing seat 47 on its outer sleeve, the bearing seat 47 is rotatably connected to the rotating shaft 414, a cylinder seat 45 is installed on one side of the bearing seat 47, and the cylinder seat 45 is fixedly connected to the top panel 41. The un-stacked tissues are transferred to the bottom of the movable plate 44. At this time, the paper feeding fixed plate 28 is in a state of being turned upward, so the tissues will enter the paper feeding fixed plate 28. The upper shift rod 49 first blocks the tissues to ensure that the tissues enter the paper feeding fixed plate 28 in an orderly manner. When the number of tissues in the paper feeding fixed plate 28 reaches a certain amount, the paddle 412 blocks the subsequent tissues to prevent too many tissues from entering. Specifically, when it is necessary to block the subsequent tissues, the third push-pull member 410 is controlled to flip the paddle 412 to the blocking position. When the blocking is released, the third push-pull member 410 drives the paddle 412 to reset, and further controls the second push-pull member 46 to extend, and drives the rotating shaft 414 to rotate through the first swing arm 48, so as to release the blocking of the tissues by the upper shift rod 49. At this time, the paper feeding fixed plate 28 flips downward to release the tissues to the pushing mechanism 5. When the tissues in the paper feeding fixed plate 28 are pushed away, it flips upward again to prepare to receive the next batch of tissues. At the same time, the third push-pull member 410 controls the paddle 412 to flip up, removing the obstruction to the subsequent paper towels, so that the new paper towels can continue to move forward and enter the paper feeding fixed plate 28. The height of the movable plate 44 can be adjusted by rotating the second adjustment screw 42, thereby changing the position of the paddle 412 relative to the paper towel flow, ensuring that they can work effectively and cooperate with the paper placing mechanism 2 to adapt to paper towels of different specifications. The design of the paper separation mechanism 4 enables it to accurately control the number of each batch of paper towels, ensuring the accuracy of the paper towel separation process and reducing quality problems caused by inconsistent paper towel quantities.The entire paper separation process is automatically controlled by multiple push-pull members (such as the second push-pull member 46 and the third push-pull member 410), which reduces the need for manual intervention and improves production efficiency. By adjusting the position of the second adjustment screw 42, the paper separation mechanism 4 can adapt to paper towels of different thicknesses and sizes without frequent adjustments to the equipment settings, thereby enhancing the flexibility of the production line.

[0034] Further, as a preferred embodiment of the present invention but not limited thereto, the panel 11 is provided with at least one push slot 111, the push mechanism 5 includes a push servo synchronous belt 52, one end of the push servo synchronous belt 52 is installed with a push servo 51, the push servo 51 is fixedly connected to the panel 11, the other end of the push servo synchronous belt 52 is installed with a synchronous wheel 53, the synchronous wheel 53 is fixedly connected to the panel 11, the push servo synchronous belt 52 is installed with a push rod plate seat 54, the push rod plate seat 54 is slidably connected to the panel 11, and a push rod 55 is slidably connected in the push slot 111, one end of the push rod 55 is fixedly connected to the push rod plate seat 54. When the paper towel is flipped to the surface of the panel 11 by the paper feeding fixing plate 28, the push mechanism 5 is started. The push servo 51 drives the push servo synchronous belt 52 to operate, thereby driving the push rod plate seat 54 to slide along the panel 11. The push rod plate seat 54 pushes the paper towel from the position of the paper placing mechanism 2 to the cross hook mechanism 6 through the fixedly connected push rod 55. Due to the sliding connection of the push rod 55 in the pushing groove 111, it is ensured that the paper towels remain neatly arranged during the pushing process and will not be offset. The pushing mechanism 5 realizes efficient pushing of paper towels through the combination of transmission belt and motor drive, ensuring that the paper towels can be quickly and accurately transferred from the paper placing mechanism 2 to the cross hook mechanism 6, thereby improving the efficiency of the entire stacking process. The transmission belt and motor drive system are relatively simple and easy to maintain and overhaul, reducing the maintenance cost and complexity of the equipment. The pushing mechanism 5 can adjust the pushing speed and force as needed to adapt to paper towels of different specifications and thicknesses, thereby enhancing the versatility and response speed of the production line.

[0035] Further, as a preferred embodiment of the present invention but not a limitation, the horizontal hook mechanism 6 includes a fourth push-pull member 62, and a horizontal hook push plate 63 is installed at one end of the fourth push-pull member 62. After the pushing mechanism 5 pushes the paper towel to the predetermined position of the horizontal hook mechanism 6, the fourth push-pull member 62 is activated. The fourth push-pull member 62 extends, driving the horizontal hook push plate 63 to move forward, and pushes the paper towel from the current position to the receiving position of the rotating mechanism 9. After the pushing is completed, the fourth push-pull member 62 contracts, so that the horizontal hook push plate 63 returns to the initial position, ready for the next pushing operation. Through the combined design of the fourth push-pull member 62 and the horizontal hook push plate 63, the horizontal hook mechanism 6 realizes efficient transfer of paper towels, ensures that the paper towels can be quickly and accurately transferred from the pushing mechanism 5 to the rotating mechanism 9, and improves the efficiency of the entire stacking process.

[0036] Further, as a preferred embodiment of the present invention but not limiting, the rotating mechanism 9 includes a rotating motor 91 installed at the bottom of the panel 11, and the rotor of the rotating motor 91 is installed with a rotating motor disk 92. When the paper towel is pushed to the position of the rotating mechanism 9 by the horizontal hook mechanism 6, the rotating motor 91 is started. The rotor of the rotating motor 91 drives the rotating motor disk 92 to rotate, and the paper towel is rotated and adjusted according to a preset angle. After the rotation is completed, the paper towel is in the correct position and is ready to be further pushed to the lifting mechanism 10 by the vertical hook mechanism 3. As needed, the rotating motor disk 92 can be rotated at multiple angles to adapt to different stacking requirements and paper towel specifications.

When the paper towel is adjusted to the correct position by the rotating mechanism 9, the vertical hook mechanism 3 is started. The vertical hook motor 31 drives the vertical hook servo synchronous belt 32 to operate, thereby driving the vertical hook push plate fixing seat 34 to slide along the vertical hook push plate slot 121. The vertical hook push plate 35 on the vertical hook push plate fixing seat 34 pushes the paper towel from the position of the rotating mechanism 9 to the lifting mechanism 10. After the pushing is completed, the vertical hook motor 31 reverses, so that the vertical hook push plate fixing seat 34 and the vertical hook push plate 35 return to the initial position, ready for the next pushing operation. The sliding connection design of the vertical hook push plate fixing seat 34 in the vertical hook push plate groove 121 ensures the accurate positioning of the paper towel during the pushing process, reduces the stacking errors caused by the misalignment of the paper towel, and improves the quality and consistency of the stacking of the paper towel.

When the paper towel is pushed to the predetermined position of the lifting mechanism 10 by the vertical hook mechanism 3, the sixth push-pull member 101 is activated. The sixth push-pull member 101 extends, driving the upper push L plate 102 to move upward, lifting the paper towel from a horizontal position to a vertical position. After the lifting is completed, the paper towel is in the correct position and is ready to be further pushed to the feeding mechanism 8 by the hook-out mechanism 7.

The paper towel stacking device designs an integrated workflow, and realizes efficient and accurate stacking of paper towels through the coordinated work of a series of mechanisms. The specific working process is as follows: the unstacked paper towels are first sent to the paper separation mechanism 4 through the conveying device. The paper separation mechanism 4 separates the continuous paper towels into single sheets or a set number of small piles, and guides them into the paper placing mechanism 2. The pushing mechanism 5 is responsible for pushing the paper towels in the paper placing mechanism 2 to the horizontal hook mechanism 6. In this process, the paper towels are preliminarily arranged and sorted. The paper towels passing through the horizontal hook mechanism 6 are then pushed to the rotating mechanism 9, which can rotate the paper towels as needed to ensure that they are in the correct direction to adapt to the subsequent processing steps. The vertical hook mechanism 3 further pushes the rotated paper towels to the lifting mechanism 10. The lifting mechanism 10 lifts the paper towels so that the paper towels can be smoothly received by the hooking mechanism 7 and finally pushed to the feeding mechanism 8. Finally, the feeding mechanism 8 conveys the already folded paper towels to prepare for the next step of processing or packaging. By introducing multiple automated mechanisms, the automation level of the paper towel stacking process is greatly improved, the need for manual intervention is reduced, and production efficiency is improved.

[0045] The paper placing mechanism 2 includes a flip shaft 26, and at least one paper feeding fixed plate 28 is installed on the side wall of the flip shaft 26. Both ends of the flip shaft 26 are installed with a paper placing servo fixed seat 27, and the paper placing servo fixed seat 27 is rotatably connected to the flip shaft 26. A paper placing servo 29 is installed on one side of the paper placing servo fixed seat 27, and the rotor of the paper placing servo 29 is fixedly connected to one end of the flip shaft 26. A lower side plate 22 is clamped on one side of the paper placing servo fixed seat 27, and the lower side plate 22 is slidably connected to the paper placing servo fixed seat 27. A first push-pull member 25 is installed on one side of the lower side plate 22, and a push-pull member support 210 is installed on one end of the first push-pull member 25. One end is fixedly connected with the paper placing servo fixing seat 27, the lower side plate 22 is sleeved with a first adjusting screw 23, the first adjusting screw 23 is threadedly connected with the lower side plate 22, the lower side plate 22 is slidably connected with the panel 11, a lower side plate fixing block 24 is arranged outside one side of the lower side plate 22, the lower side plate fixing block 24 is sleeved outside the first adjusting screw 23, the first adjusting screw 23 is rotatably connected with the lower side plate fixing block 24, the lower side plate fixing block 24 is fixedly connected with the side plate 12, a lower side plate adjusting slider 21 is installed on one side of the lower side plate 22, a guide rail that is clamped with the lower side plate adjusting slider 21 is installed on one side of the side plate 12, and the guide rail is slidably connected with the lower side plate adjusting slider 21. The paper feeding fixing plate 28 is installed on the side wall of the flip shaft 26, and is used to receive the paper towel transmitted from the paper separation mechanism 4. When the paper towel needs to be flipped to the surface of the panel 11, the paper placing servo 29 is driven, and the rotor of the motor is fixedly connected with one end of the flip shaft 26. After the motor is started, the flip shaft 26 rotates, driving the paper feed fixing plate 28 to rotate together, thereby flipping the paper towel in the paper feed fixing plate 28 to the surface of the panel 11, so that the pushing mechanism 5 can smoothly push the paper towel. By controlling the telescopic action of the first push-pull member 25, the paper placing servo fixing seat 27 can be driven to rise and fall, and then the height of the flip shaft 26 and the paper feeding fixing plate 28 thereon can be adjusted to ensure that the paper towel can be processed at the correct height. The lower side plate 22 is sleeved with a first adjusting screw 23, and the two are connected by a thread. When the first adjusting screw 23 is rotated, the lower side plate 22 can be moved along the guide rail direction by the action of the thread. As the lower side plate 22 moves, the lower side plate 22 will drive the flip shaft 26 to move together through the paper placing servo fixing seat 27, thereby changing the position of the paper feeding fixing plate 28 relative to the paper separation mechanism 4, ensuring that it can adapt to paper towels of different specifications. By adjusting the position and height of the paper feeding fixing plate 28, the paper placing mechanism 2 can automatically adapt to paper towels of different thicknesses and sizes. A lower side plate adjusting slider 21 is installed on one side of the lower side plate 22, and a guide rail is provided on one side of the side plate 12 to be clamped therewith. The sliding connection between the two not only provides additional stability, but also ensures that the lower side plate 22 moves in a straight line along the predetermined track to avoid deviation or tilting.

[0046] The paper separation mechanism 4 includes a second adjusting screw rod 42, the second adjusting screw rod 42 is sleeved in the top panel 41, the top panel 41 is threadedly connected to the second adjusting screw rod 42, one end of the second adjusting screw rod 42 is rotatably connected to a movable plate 44, the movable plate 44 is equipped with at least one pivot shaft 43, the pivot shaft 43 is sleeved in the top panel 41, the pivot shaft 43 is slidably connected to the top panel 41, the bottom of the movable plate 44 is hinged with a third push-pull member 410, one end of the third push-pull member 410 is hinged with a second swing arm 411, one side of the second swing arm 411 is equipped with a lower shaft 415, the lower shaft 415 is equipped with a paddle 412, and the lower The shaft 415 is provided with a seat bearing 413, which is rotatably connected to the lower shaft 415, and the seat bearing 413 is fixedly connected to the movable plate 44. The bottom of the top panel 41 is hinged with a second push-pull member 46, and one end of the second push-pull member 46 is hinged with a first swing arm 48. A rotating shaft 414 is installed on one side of the first swing arm 48, and at least one upper shifting rod 49 is installed on the side wall of the rotating shaft 414. The rotating shaft 414 is provided with a bearing seat 47, which is rotatably connected to the rotating shaft 414, and a cylinder seat 45 is installed on one side of the bearing seat 47. The cylinder seat 45 is fixedly connected to the top panel 41. The unfolded paper towels are conveyed to the bottom of the movable plate 44. At this time, the paper feeding fixed plate 28 is in a flipped upward state, so the paper towels will enter the paper feeding fixed plate 28. The upper shifting rod 49 first blocks the paper towels preliminarily to ensure that the paper towels enter the paper feeding fixed plate 28 in an orderly manner. When the number of paper towels in the paper feeding fixed plate 28 reaches a certain amount, the paddle 412 blocks the subsequent paper towels to prevent too many paper towels from entering. Specifically, when it is necessary to block the subsequent paper towels, the third push-pull member 410 is controlled to flip the paddle 412 to the blocking position. When the blocking is released, the third push-pull member 410 drives the paddle 412 to reset, and further controls the second push-pull member 46 to extend, and drives the rotating shaft 414 to rotate through the first swing arm 48, so as to release the blocking of the paper towels by the upper gear lever 49. At this time, the paper feeding fixed plate 28 flips down and releases the paper towels to the pushing mechanism 5. When the paper towels in the paper feeding fixed plate 28 are pushed away, it flips up again to prepare to receive the next batch of paper towels. At the same time, the third push-pull member 410 controls the paddle 412 to flip up, so as to release the blocking of the subsequent paper towels, so that the new paper towels can continue to move forward and enter the paper feeding fixed plate 28. The height of the movable plate 44 can be adjusted by rotating the second adjusting screw 42, thereby changing the position of the paddle 412 relative to the paper towel flow, ensuring that they can work effectively and cooperate with the paper placing mechanism 2 to adapt to paper towels of different specifications. The design of the paper separation mechanism 4 enables it to accurately control the number of paper towels in each batch, ensuring the accuracy of the paper towel stacking process and reducing quality problems caused by inconsistent paper towel quantities. The entire paper separation process is automatically controlled by multiple push-pull members (such as the second push-pull member 46 and the third push-pull member 410), reducing the need for manual intervention and improving production efficiency.By adjusting the position of the second adjusting screw 42, the paper separation mechanism 4 can adapt to paper towels of different thicknesses and sizes without frequently adjusting the equipment settings, thereby enhancing the flexibility of the production line.

[0047] The panel 11 is provided with at least one push slot 111. The push mechanism 5 includes a push servo synchronous belt 52. A push servo 51 is installed at one end of the push servo synchronous belt 52. The push servo 51 is fixedly connected to the panel 11. A synchronous wheel 53 is installed at the other end of the push servo synchronous belt 52. The synchronous wheel 53 is fixedly connected to the panel 11. A push rod plate seat 54 is installed on the push servo synchronous belt 52. The push rod plate seat 54 is slidably connected to the panel 11. A push rod 55 is slidably connected in the push slot 111. One end of the push rod 55 is fixedly connected to the push rod plate seat 54. When the paper towel is flipped to the surface of the panel 11 by the paper feeding fixed plate 28, the push mechanism 5 is started. The push servo 51 drives the push servo synchronous belt 52 to operate, thereby driving the push rod plate seat 54 to slide along the panel 11. The push rod plate seat 54 pushes the paper towel from the position of the paper placing mechanism 2 to the horizontal hook mechanism 6 through the fixedly connected push rod 55. Due to the sliding connection of the push rod 55 in the pushing groove 111, it is ensured that the paper towels remain neatly arranged during the pushing process and will not be offset. The pushing mechanism 5 realizes efficient pushing of paper towels through the combination of transmission belt and motor drive, ensuring that the paper towels can be quickly and accurately transferred from the paper placing mechanism 2 to the cross hook mechanism 6, thereby improving the efficiency of the entire stacking process. The transmission belt and motor drive system are relatively simple and easy to maintain and repair, reducing the maintenance cost and complexity of the equipment. The pushing mechanism 5 can adjust the pushing speed and force as needed to adapt to paper towels of different specifications and thicknesses, thereby enhancing the versatility and response speed of the production line.

[0048] The horizontal hook mechanism 6 includes a fourth push-pull member 62, and a horizontal hook push plate 63 is installed at one end of the fourth push-pull member 62. When the pushing mechanism 5 pushes the paper towel to the predetermined position of the horizontal hook mechanism 6, the fourth push-pull member 62 is started. The fourth push-pull member 62 extends, drives the horizontal hook push plate 63 to move forward, and pushes the paper towel from the current position to the receiving position of the rotating mechanism 9. After the pushing is completed, the fourth push-pull member 62 contracts, so that the horizontal hook push plate 63 returns to the initial position, ready for the next pushing operation. Through the combined design of the fourth push-pull member 62 and the horizontal hook push plate 63, the horizontal hook mechanism 6 realizes the efficient transfer of paper towels, ensures that the paper towels can be quickly and accurately transferred from the pushing mechanism 5 to the rotating mechanism 9, and improves the efficiency of the entire stacking process. The rotating mechanism 9 includes a rotating motor 91 installed at the bottom of the panel 11, and the rotor of the rotating motor 91 is installed with a rotating motor disk 92. When the paper towel is pushed to the position of the rotating mechanism 9 by the horizontal hook mechanism 6, the rotating motor 91 is started. The rotor of the rotary motor 91 drives the rotary motor disk 92 to rotate, and the paper towel is rotated and adjusted according to a preset angle. After the rotation is completed, the paper towel is in the correct position and is ready to be further pushed to the lifting mechanism 10 by the vertical hook mechanism 3. As needed, the rotary motor disk 92 can be rotated at multiple angles to meet different stacking requirements and paper towel specifications.

[0049] The side plate 12 is provided with a vertical hook push plate slot 121, and the vertical hook mechanism 3 includes a vertical hook servo synchronous belt 32. A vertical hook push plate fixing seat 34 is slidably connected in the vertical hook push plate slot 121. The vertical hook push plate fixing seat 34 is fixedly connected to the vertical hook servo synchronous belt 32. A vertical hook push plate 35 is installed on one side of the vertical hook push plate fixing seat 34. A vertical hook motor 31 is installed at one end of the vertical hook servo synchronous belt 32. The vertical hook motor 31 is fixedly connected to the side plate 12. A vertical hook synchronous wheel 33 is installed at the other end of the vertical hook servo synchronous belt 32. The vertical hook synchronous wheel 33 is fixedly connected to the side plate 12. When the paper towel is adjusted to the correct position by the rotating mechanism 9, the vertical hook mechanism 3 is started. The vertical hook motor 31 drives the vertical hook servo synchronous belt 32 to operate, thereby driving the vertical hook push plate fixing seat 34 to slide along the vertical hook push plate slot 121. The vertical hook push plate 35 on the vertical hook push plate fixing seat 34 pushes the paper towel from the position of the rotating mechanism 9 to the lifting mechanism 10. After pushing is completed, the vertical hook motor 31 reverses, so that the vertical hook push plate fixing seat 34 and the vertical hook push plate 35 return to the initial position, ready for the next pushing operation. The sliding connection design of the vertical hook push plate fixing seat 34 in the vertical hook push plate slot 121 ensures the accurate positioning of the paper towels during the pushing process, reduces the stacking errors caused by the misalignment of the paper towels, and improves the quality and consistency of the paper towel stacking.

[0050] The lifting mechanism 10 includes a sixth push-pull member 101 installed at the bottom of the panel 11, and an upper push L plate 102 is installed at one end of the sixth push-pull member 101. When the paper towel is pushed to the predetermined position of the lifting mechanism 10 by the vertical hook mechanism 3, the sixth push-pull member 101 is activated. The sixth push-pull member 101 extends, driving the upper push L plate 102 to move upward, lifting the paper towel from a horizontal position to a vertical position. After the lifting is completed, the paper towel is in the correct position and is ready to be further pushed to the feeding mechanism 8 by the hook-out mechanism 7. As needed, the upper push L plate 102 can adjust the lifting height to accommodate paper towels of different specifications and thicknesses. The hook-out mechanism 7 includes a hook-out panel 71, and the hook-out panel 71 is installed with a fifth push-pull member 72, and one end of the fifth push-pull member 72 is installed with a hook-out push plate 73. When the paper towel is lifted to the correct position by the lifting mechanism 10, the hooking mechanism 7 is started, and the hooking mechanism 7 is turned on. The hooking push plate 73 on the fifth push-pull member 72 pushes the paper towel from the position of the lifting mechanism 10 to the feeding mechanism 8. After the pushing is completed, the fifth push-pull member 72 is reset to prepare for the next pushing operation. The feeding mechanism 8 includes a belt bracket 81, in which a feeding belt 83 is installed, and a feeding belt motor 82 is installed at one end of the feeding belt 83. The feeding belt motor 82 is used to provide power for the feeding belt 83, and a baffle plate 84 is installed on both sides of the belt bracket 81. When the paper towel is pushed to the predetermined position of the feeding mechanism 8 by the hooking mechanism 7, the feeding belt motor 82 is started. The feeding belt motor 82 drives the feeding belt 83 to operate and transport the paper towel from one end of the feeding mechanism 8 to the other end. During the conveying process, the baffle plate 84 ensures that the paper towel remains on the feeding belt 83 to prevent it from deflecting or falling. After the conveying is completed, the paper towel arrives at the designated position and is ready for the next step.

[0051] The paper placing servo 29, the vertical hook motor 31, the material pushing servo 51, the feeding belt motor 82, and the rotating motor 91 are all servo motors. The servo motor can accurately control the rotation angle of the flip shaft 26, ensuring that the angle of each flip of the paper feeding fixed plate 28 is consistent, thereby improving the accuracy of paper towel stacking. The constant thrust provided by the servo motor ensures that the vertical hook push plate fixing seat 34 and the vertical hook push plate 35 can push the paper towels smoothly, reducing the paper towel stacking errors or jamming problems caused by uneven pushing. The material pushing servo synchronous belt 52 driven by the servo motor can quickly and accurately transfer the paper towels from the paper placing mechanism 2 to the horizontal hook mechanism 6, thereby improving the efficiency of the entire stacking process. The servo motor can accurately control the speed and position of the feeding belt 83, ensuring that the paper towels can accurately reach the specified position to avoid deviation or falling. The servo motor can achieve multi-angle rotation, ensuring that the rotating motor disk 92 can adjust the paper towels to the correct position to meet different stacking requirements.

[0052] The first push-pull member 25 , the second push-pull member 46 , the third push-pull member 410 , the fourth push-pull member 62 , and the sixth push-pull member 101 are cylinders.

[0053] Specifically, the working principle of the present invention is as follows:

[0054] The paper towel stacking device first delivers the unstacked paper towels to the paper separation mechanism 4 through the conveying device. The paper separation mechanism 4 uses the second adjusting screw 42 and multiple push-pull members (such as the third push-pull member 410 and the second push-pull member 46) to accurately control the movement of the paddle 412 and the upper shift rod 49 to ensure that the paper towels are separated into single sheets or a set number of small piles, and enter the paper placement mechanism 2 in an orderly manner. The paper feeding fixed plate 28 in the paper placement mechanism 2 is flipped under the action of the flip shaft 26 driven by the paper placement servo 29, and the paper towels are flipped to the surface of the panel 11, preparing for the subsequent pushing operation.

[0055] After the paper towel is on the surface of the panel 11, the pushing mechanism 5 is started, and the pushing servo synchronous belt 52 driven by the pushing servo 51 drives the push rod 55 to push the paper towel from the position of the paper placing mechanism 2 to the horizontal hook mechanism 6. The fourth push-pull member 62 in the horizontal hook mechanism 6 drives the horizontal hook push plate 63 to push the paper towel further to the rotating mechanism 9. The rotating mechanism 9 is driven by the rotating motor disk 92 of the rotating motor 91 to adjust the paper towel at multiple angles to ensure that its direction is correct to meet the needs of subsequent processing steps.

[0056] After the rotation adjustment, the paper towel is pushed to the lifting mechanism 10 by the vertical hook servo synchronous belt 32 driven by the vertical hook motor 31 in the vertical hook mechanism 3. The lifting mechanism 10 lifts the paper towel from the horizontal position to the vertical position through the upward push L plate 102 driven by the sixth push-pull member 101. Then, the fifth push-pull member 72 in the hook-out mechanism 7 pushes the paper towel to the feeding mechanism 8. Finally, the feeding belt motor 82 in the feeding mechanism 8 drives the feeding belt 83 to smoothly convey the folded paper towels to prepare for the next step of processing or packaging. The whole process is highly automated, which significantly improves production efficiency and product quality.

[0057] By adopting components such as servo motors and cylinders / electric push rods, the device not only achieves high precision and high efficiency in paper towel folding, but also enhances the overall stability and reliability of the equipment to meet the needs of paper towels of different specifications.

[0058] In summary, the present invention solves the problems of low automation and precision in the existing paper towel folding process, a fixed paper feeding mechanism, and the need to replace the paper feeding paper board when the thickness of the paper towel changes, which results in time required for readjustment when the machine is turned on next time.

[0059] It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information. In addition, the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0060] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
