[0022] A crease roller 5 is installed on the rack 1, the crease roller 5 is a pair of rollers, intermittent notch blades are installed on the pair of rollers, and then point-breaks are processed on the paper towels; a folding knife group is installed on the lower side of the crease roller 5, the folding knife group comprises folding pairs of rollers 6, suction grooves and crease top rods are processed on the folding pairs of rollers 6 at intervals, the crease positions are alternately attached to the two folding pairs of rollers 6, and then folding is formed after falling; the suction grooves are connected to a negative pressure pipe through communication cavities processed on the folding pairs of rollers 6, the negative pressure pipe is connected to a negative pressure tank through a main air pipe, and then negative pressure is formed at the suction grooves to adsorb the crease positions.

[0023] The folding knife group is provided with a paper receiving die group, the paper receiving die group comprises a pawl assembly 7, the pawl assembly 7 comprises a pawl main shaft 701, the pawl main shaft 701 is connected with a pawl 703, in the process of rotating of the folding roller 6, the paper towel is pushed down by the pawl 703 assembly 7, so that the crease is separated from the adsorption groove, and then the paper towel can fall down in an orderly manner. In the embodiment, in order to save space, liquid is added to the paper towel through the pawl 703, the pawl 703 comprises a connecting part 708, the connecting part 708 is processed with an elongated adjusting hole 705, the connecting part 708 is connected with an extension part 709, the extension part 709 is connected with a claw head 713 at the tail end, the connecting part 708, the extension part 709 and the claw head 713 are integrally formed, and the structure is high in strength and high in sealing performance. The claw head 713 is connected with a liquid adding structure, the liquid adding structure comprises a liquid adding hole 710 processed on the claw head, the liquid adding hole 710 has two rows, the two rows of liquid adding holes 710 are inclined forward and outward, so that the liquid is completely sprayed on the paper towel when the paper towel is close, and the dispersion to the side is reduced. It is found in the test that the liquid adding position can be accurately controlled through the liquid adding hole 710, but due to the high action frequency of the pawl 703, there is a delay in liquid adding of the liquid adding hole 710 after the action of the electromagnetic valve, and the liquid adding amount is small, so it is necessary to enlarge the hole diameter of the liquid adding hole 710 and increase the liquid adding pressure, which makes the pawl 703 become fragile and reduces the service life. In the embodiment, the pawl main shaft 701 and the claw head 713 are further provided with a liquid outlet control structure, the liquid outlet control structure comprises an extension block 702 mounted on the pawl main shaft 701, the extension block 702 is connected to the lower side of the pawl main shaft 701, the connecting part 708 is connected to the tail end of the extension block 702 through an adjusting hole, and the included angle between the extension block 702 and the connecting part 708 is 80-100°. The angle between the extension block 702 and the connecting part 708 is adjusted, the liquid inlet pressure is adjusted, the purpose of adjusting the liquid adding effect is achieved, the extension part 709 is integrally formed with a liquid storage part 712, the extension part 709 is a U-shaped opening upward, so that the volume of the liquid storage part 712 can be increased. In the process of swinging downward of the claw head 713, the liquid storage part 712 swings from an inclined upward to an inclined downward, so as to drive the claw head 713 to push down the paper towel. Under the action of centrifugal force, the liquid in the liquid storage part 712 is rapidly pressurized to the claw head 713, the electromagnetic valve is opened to increase the pressure, so as to increase the liquid outlet amount of the liquid adding hole 710. The cross section of the claw head 713 is rectangular, the liquid adding hole 710 is processed on the lower side wall of the claw head 713. When the claw head 713 swings upward, the electromagnetic valve is closed, the pressure at the liquid adding hole 710 is reduced, and the liquid adding hole 710 is processed on the lower side wall of the claw head 713, so it will not overflow. In the test, the liquid storage part 712 is tried to be made into a flat shape or a circular arc shape, and the end is inclined upward and connected with the claw head 713. It is found in the test that when the liquid pipe is connected to the connecting end of the liquid storage part 712, the connection between the liquid pipe and the liquid storage part 712 is subjected to high-frequency changing force, the connection is easy to fatigue damage, and then liquid leakage is caused.When the liquid pipe is connected to the middle position of the liquid storage part 712, interference is easy to occur again. In the present embodiment, a biasing block 706 is integrally formed at the connection between the connecting part 708 and the extension part 709, the biasing block 706 is distributed on the side away from the extension block 702, a connecting hole is processed on the biasing block 706, and then a first connecting joint 707 is connected, the liquid pipe is connected through the first connecting joint 707, and then connected to the liquid tank through the management with the electromagnetic valve. After the liquid tank is pressurized by the booster pump, the high pressure in the liquid tank is ensured, the liquid is discharged through the liquid pipe and the liquid filling hole 710. In the process of use, the first connecting joint 707 is connected to the side away from the extension block 702. Not only can the interference between the liquid pipe and the extension block 702 be avoided, but also a pressurizing cavity 711 can be formed between the biasing block 706 and the extension part 709. The liquid in the liquid pipe first enters the pressurizing cavity 711, so that the pressure in the liquid storage part 712 increases rapidly, instead of forming a jet. The liquid in the pawl 703 changes direction several times, and the centrifugal force of the liquid overcomes the gravity in the process of swinging upward, and resistance is formed at the turning point, thereby reducing the liquid backflow, stabilizing the liquid filling amount, and no longer dripping in the process of swinging upward. In the process of use, the liquid storage part 712 is also used to avoid the folding roller 6, so that the claw head 713 extends to the middle position close to the folding roller 6, and then the claw head 713 is close to the middle position of the adjacent two creases. In addition, due to the installation of the extension block 702, the connecting part 708 is away from the axis of the pawl main shaft 701. Correspondingly, the claw head 713 forms a backstroke in the process of downwardly pushing the paper towel, so that the paper towel is more neat in stacking, and the liquid discharge hole is rubbed with the paper towel, thereby reducing the liquid residue at the liquid discharge hole.

[0024] The liquid outlet control structure further comprises an angle detection mechanism connected with the pawl main shaft 701, the angle detection mechanism comprises a potentiometer 704, the potentiometer 704 detects the rotation angle of the pawl main shaft 701 and sends an electric signal to the controller, the controller detects the electric signal to determine the rotation angle of the pawl main shaft 701, and then controls the electromagnetic valve to act, the electromagnetic valve is connected when the pawl head 713 swings downward, and the electromagnetic valve is disconnected when the pawl head 713 swings upward, so as to accurately control the rotation angle of the pawl main shaft 701.

In the process of swinging downward of the pawl head 713, the liquid storage part 712 swings from oblique upward to oblique downward, and then drives the pawl head 713 to push the paper towel downward. Under the action of centrifugal force, the liquid in the liquid storage part 712 is rapidly pressurized to the pawl head 713, and the pressurization is opened by cooperating with the electromagnetic valve action, and then the liquid outlet amount of the liquid filling hole 710 is increased. When the pawl head 713 swings upward, the electromagnetic valve action is closed, and the pressure at the liquid filling hole 710 is reduced. Since the liquid filling hole 710 is processed on the lower sidewall of the pawl head 713, it will not overflow. The point break continuous paper towel falls to the pre-connection paper fork plate, the pre-connection paper plug is lowered, and the paper towel is placed on the cloth insertion plate. The pre-connection paper plug 803 has two groups and is distributed on both sides of the folding pair of rollers 6. When the first group of pre-connection paper plugs 803 is lowered to a predetermined height, it has received a predetermined number of paper towels. The second group of pre-connection paper plugs 803 is transversely moved to the upper side of the first group of pre-connection paper plugs 803. The second group of pre-connection paper plugs 803 corresponds to the action of the pull-off plug 905, and the paper towel on the lower side of the second group of pre-connection paper plugs 803 is pulled off. The pull-off plug 905 is reset, the disturbance assembly stops working, the first group of pre-connection paper plugs 803 continues to descend to place the paper towel on the paper receiving plate 1103, the first group of pre-connection paper plugs 803 is transversely moved out, and then is moved upward to reset. When the second group of pre-connection paper plugs 803 is lowered to a predetermined height, the first group of pre-connection paper plugs 803 is transversely moved to the upper side of the second group of pre-connection paper plugs 803, and then the working cycle is repeated. The paper receiving plate 1103 moves to be close to the discharging conveyor belt 10 and stops descending. The push structure acts to push the stacked paper towel on the paper receiving plate 1103 to the discharging conveyor belt 10, and the paper receiving plate 1103 is reset.

[0030] Embodiment 2 As Figures 15-16As shown, a point break on-line humidification continuous extraction paper towel integrated production equipment, different from embodiment 1 is that a switch structure is also installed at the claw head 713, the switch structure includes a socket 721 processed on the upper side wall of the inner end of the claw head 713, a floating baffle 722 is worn at the socket 721, the floating baffle 722 includes a lead core 723 and a nylon layer wrapped outside the lead core 723, the floating baffle 722 is gap fitted with the socket 721, the nylon itself has good structural strength and lubricating property, thereby being able to float along the socket 721, a sealing cover 719 is connected with the outside of the socket 721 through a sealing connecting ring 720, the sealing cover 719 is a stainless steel cover, the sealing connecting ring 720 is sealingly welded with the stainless steel cover, the sealing connecting ring 720 is sealed with the outer wall of the claw head 713 through a sealing gasket, a buffer head 724 is integrally formed on the upper end of the floating baffle 722, the thickness value of the buffer head 724 is greater than that of the floating baffle 722, in the working process, the buffer head 724 is in turn contacted with the sealing cover 719 and the pawl 703, avoiding extrusion and collision between the floating baffle 722 and the claw head 713, the lead core 723 has large density, thereby being able to provide greater inertial potential energy for the floating baffle 722, and the relative movement between the floating baffle 722 and the socket 721 is more stable.

[0031] In the use process, the claw head 713 is driven by the pawl main shaft 701 to swing at high frequency, When the claw head 713 swings downward, the floating baffle 722 moves upward relative to the claw head 713 under the action of inertia, thereby making the claw head 713 communicate with the liquid storage part 712, realizing liquid addition to the paper towel, when the claw head 713 swings to a lower position and slows down, the floating baffle 722 moves downward relative to the claw head 713 under the action of inertia, thereby making the claw head 713 disconnected with the liquid storage part 712, and the liquid addition stops; When the claw head 713 swings upward, the floating baffle 722 does not move relative to the claw head 713, when the claw head 713 swings to a higher position and slows down, the floating baffle 722 moves upward relative to the claw head 713 under the action of inertia, thereby making the claw head 713 communicate with the liquid storage part 712.

[0032] Since the claw head 713 is driven by the pawl main shaft 701 to swing at high frequency, the swing angle of the claw head 713 is controlled, and when the claw head 713 swings to a higher position without interference, the corresponding paper towel has been located below the claw head 713.

[0033] Through the point break on-line humidification continuous extraction paper towel integrated production equipment provided in the embodiment, the on-off can be automatically controlled under high-frequency working state, thereby enabling the high pressure in the liquid storage part 712 to work normally, the liquid addition amount and stability are improved through high pressure, and in some embodiments, the liquid can be continuously supplied into the liquid storage part 712 through a gear pump.

[0034] During the test, attempts are made to use valve structure, for example, install press valve matched with paper towel at liquid filling hole 710, which is pressed open when the press valve is in contact with the paper towel, the test finds that it cannot adapt to high frequency work, and the trigger is unstable, and attempts are also made to control the electromagnetic valve, which starts to act to open during the swinging of the claw head downward, and is disconnected when the claw head swings upward to the predetermined position, because the hydraulic transmission delay is large, the control accuracy is low, and the switch structure provided by the embodiment can be automatically controlled, the switch structure is installed at the claw head position, the linear speed is large, and further has greater inertial potential, the opening and closing are more stable, and the disadvantage is that the wear is more serious, and regular maintenance is required.

[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the present application.
