In this embodiment, the number of the material unwinding devices 10 is 3, that is, the system completes the compounding of 3 materials; the present embodiment is not limited to the compounding of the above 3 materials, and the number of the material unwinding devices 10 may be increased or decreased as appropriate according to the actual needs. The material type can be determined according to the actual situation, and the method is not only suitable for compounding various non-woven fabrics, but also suitable for compounding non-woven fabrics and elastic materials.

The wrap angle is the central angle corresponding to the contact arc length formed by the material before composite embossing and the material after composite embossing on the ultrasonic bottom roller 31, so that the position of one side of the wrap angle is changed by the up-down adjustable setting of the second free roller 101 in the adjustable free roller device 100, namely, the wrap angle of each material and the ultrasonic bottom roller 31 is directly influenced. The adjustable free roller device 100 can independently find the optimal composite wrap angle for each material before the materials are compounded according to the influencing factors of different materials, different gram weights and different layers, and provides preconditions for ensuring the composite effect of the multi-layer materials.
The installation height of the second free roller 101 is not higher than the installation height of the composite position of the ultrasonic device 20 or the extractable driving roller device 30. This arrangement is to ensure that the materials contact the ultrasound backing roll 31 and do not cause failure of the second free roll 101. In general, the smaller the wrap angle, i.e., the smaller the contact range between each material before the composite embossing and the material after the composite embossing and the ultrasonic bottom roller 31, the poor the composite effect.

The first nip roller 61 is finely adjusted in the MD to change the position of the other side of the wrap angle, i.e., to directly affect the wrap angle of each material with the ultrasonic bottom roller 31. Aiming at different requirements on wrap angles when different materials are compounded, the compound embossing effect reaches the optimal state and keeps the stable output of tension; and, the cooperation of the guide rail pair 65 and the gear pair 66 makes the precise adjustment process more stable and controllable.

When the ultrasonic compounding process requires the first clamping roller 61 and the ultrasonic bottom roller 31 to clamp the compounded material, the piston end of the second driving cylinder 62 extends out, and the third connecting plate 631 connected with the piston end of the second driving cylinder 62 rotates by using the third rotating shaft 611 to enable the first clamping roller 61 to rotate at a certain angle (that is, the linear motion of the second driving cylinder 62 is converted into the rotary motion of the third rotating shaft 611) until the first clamping roller 61 contacts with the ultrasonic bottom roller 31 and clamps the compounded and embossed material; when the ultrasonic compounding process does not require the first nip roller 61 and the ultrasonic bottom roller 31 to nip the compounded material, the piston end of the second driving cylinder 62 is retracted, and the third connecting plate 631 connected to the piston end of the second driving cylinder 62 rotates by the third rotating shaft 611, so that the first nip roller 61 is reversed by a certain angle (relative to the extended state of the second driving cylinder 62) until the first nip roller 61 is separated from the ultrasonic bottom roller 31. The air inlet and outlet of the second driving cylinder 62 and the corresponding clamping and separating modes thereof can be set according to practical situations. The first nip roller 61 and the ultrasonic bottom roller 31 are in contact or separation, and can be selected according to different materials and different composite embossing requirements, so that the method is flexible and convenient in practical application process. The flow centers of all the devices described in the above embodiments are identical, and the flow centers refer to distances from the mounting surface of each device to the center of each device in the width direction (CD direction) in the flow of the apparatus.
The working principle of the invention is as follows:
before the composite system is started, firstly, a raw material roll with a certain diameter after measurement is arranged on 3 inflatable shaft units 11 at an uncoiling device 10, then, the diameter value of the roll is input into a display screen, and the rotating speed of the inflatable shaft units 11 is automatically converted by a control system according to a certain linear speed. Materials are manually distributed at different stations in the system, and the adjusting assembly 102 in the adjustable free roller device 100 is manually adjusted, so that the optimal composite wrap angle can be independently found for each material before the materials are compounded by continuously adjusting the upper and lower positions of the second free roller 101, and preconditions are provided for ensuring the compounding effect of the multi-layer materials.
Before the composite system is started, the ultrasonic bottom roller 31 needs to be roughly adjusted in the MD direction by using the other guide rail pair 348, then the ultrasonic bottom roller 31 needs to be finely adjusted in the MD direction again by using the adjusting mechanism 347, and the extractable driving roller device 30 is positioned after the adjustment is completed. The mounting position of the ultrasonic device 20 needs to be appropriately adjusted to ensure the optimal combination position, and the horizontal movement mechanism and the vertical movement mechanism are adjusted to move the ultrasonic mechanism 21 in the CD direction and the vertical direction, so that the ultrasonic horn in the ultrasonic mechanism 21 can obtain the optimal combination position in the up-down direction and the CD direction with respect to the ultrasonic bottom roller 31. Typically, the line connecting the center of the ultrasonic horn and the center of the ultrasonic foot roll 31 is a vertically downward horizontal line (the position shown in fig. 1). However, the ultrasonic horn may be set to the left or right of the vertical-down horizontal line by precise adjustment of the ultrasonic bottom roller 31 in the MD direction again according to the actual adjustment, and the above setting mode may change the composite embossing effect and the tension value during the composite process of the material to some extent. Therefore, the joint adjustment of the ultrasonic device 20 and the extractable driving roller device 30 can simultaneously satisfy the multi-directional adjustment of the ultrasonic horn and the ultrasonic bottom roller 31 in the vertical direction (up and down), the CD direction (flow center) and the MD direction, so that the performance and the application range of each device are greatly improved.
Then, based on the tension value of the material before the operation of the composite system, presetting the air pressure value of the air inflow of the first driving cylinder 733 in the tension control device 70 corresponding to the tension balance of the material on a control screen of the control unit, and enabling the air pressure value of the first driving cylinder 733 to reach a preset value by utilizing an electric proportional valve; after the composite system is started to operate, the material is unwound and output from the material unwinding device 10 and then conveyed to the downstream side station through the first free roller 72, and when the first handle arm 74 and the first free roller 72 connected with the first handle arm are in a vertically downward state, the tension value in the material conveying process is in an ideal state, namely, is consistent with the preset value of the material tension.
When the tension force during material conveying is larger than the preset pressure value of the first driving cylinder 733, at this time, the tension force of the material is too large, the material is in an overtightening state, the first handle arm 74 and the first free roller 72 connected with the first handle arm are driven by the first driving component 73 to swing the material to the loosened side by a certain angle, the encoder feeds back signals to the control unit, and the control unit controls the uncoiling motor in the material uncoiling device 10 or the coiling motor in the material coiling device 50 to decelerate according to the swinging angles of the first handle arm 74 and the first free roller 72 connected with the first handle arm to enable the tension force to reach an ideal state.
When the tension value of the material during conveying is smaller than the preset pressure value of the first driving cylinder 733, the tension value of the material is too small, the material is in an excessively loose state, the first handle arm 74 and the first free roller 72 connected with the first handle arm are driven by the first driving component 73 to swing to the tightened side by a certain angle, the encoder feeds back signals to the control unit, and the control unit controls the uncoiling motor in the material uncoiling device 10 or the coiling motor in the material coiling device 50 to accelerate according to the swinging angles of the first handle arm 74 and the first free roller 72 connected with the first handle arm to enable the tension value to reach an ideal state.
The tension control device 70 can control the tension value before and after material compounding in real time during the running process of the system. When the tension control device 70 is arranged on a station before material compounding, an encoder feeds back a signal to a control unit, and the control unit controls the rotating speed of an uncoiling motor on the upstream side according to the swinging angle of the first handle arm 74 and the first free roller 72 connected with the first handle arm; when the tension control device 70 is arranged on the station after the materials are compounded, an encoder feeds back a signal to a control unit, and the control unit controls the rotating speed of a winding motor in the material winding device 50 according to the swinging angle of the first handle arm 74 and the first free roller 72 connected with the first handle arm. The tension control device 70 in front of the material winding device 50 changes the preset tension value according to the change of the diameter of the winding material roll in the process of controlling the tension of the same composite material winding. Specifically, when the winding diameter is small, the tension value of the composite embossed material is large so as to wind up the small-diameter composite embossed material (the winding is more compact); when the winding diameter becomes larger, the tension value of the composite embossed material becomes correspondingly smaller (the winding becomes loose). Therefore, the air intake value of the first driving cylinder 733 will also be changed frequently, and the electric proportional valve provided in the tension control device 70 can quickly reach the preset accurate pressure value for the air intake amount of the first driving cylinder 733 when the tension of the same kind of composite embossing material is controlled, that is, the air intake values of various first driving cylinders 733 are preset on the operation panel in advance, and when the pressure value needs to be changed in the production process, the corresponding preset value is quickly selected on the operation panel. Because the electric proportional valve replaces the regulation of a manual valve, the pressure control is more accurate due to the arrangement, the error of manual regulation is avoided greatly, the working efficiency is improved, and the conditions that the same material needs to change the preset tension value frequently and the scene that the material needs to be replaced frequently are met.
The tension control device 70 in the invention has a compact structure, does not occupy installation space and does not need to consider the balance problem under the gravity of the first free roller 72, can accurately ensure the tension value of the material, the tension control device 70 arranged in front of the composite station can timely feed back with the uncoiling motor at the upstream side, and the uncoiling motor controls the rotating speed to realize the adjustment of the tension of the material, thereby forming a closed loop in the adjustment process and ensuring more accurate tension control before the material is compounded;
the second free roller 101 in the adjustable free roller device 100 arranged at the composite front station can adjust the upper and lower positions of the second free roller 101 under the adjusting action of the adjusting component 102, so that the wrap angle between the material and the ultrasonic bottom roller 31 is changed, and the optimal composite wrap angle when the ultrasonic device 20 and the ultrasonic bottom roller 31 are subjected to ultrasonic composite is found; the adjustment of the station can be operated before the system is started;
