[0028] In actual application, the material passes through the front guide roller 3 and the slitting mechanism 2 in sequence, the slitting mechanism 2 slits the material into two material strips, the two material strips pass through the middle guide roller 5 and the roller traction mechanism 4 respectively, the roller traction mechanism 4 pulls the two material strips to move the two material strips, the two material strips are respectively wound around the corresponding rear guide roller 7 and then wound through the corresponding non-stop winding device 6, and the two non-stop winding devices 6 respectively wind up the two material strips. The utility model uses two non-stop winding devices 6 to respectively wind up the two slit material strips non-stop, so as to separately wind up the two slit material strips and wind them up on two paper rolls, thus saving the subsequent process of separating the two material strips on the same paper roll, and solving the problem of overlapping wrinkles and unstable tension when one winding device winds up the two slit material strips in the prior art.

[0029] In this embodiment, the non-stop winding device 6 includes a pressing and cutting mechanism 8 movably arranged on the machine base 1, a turntable 9 rotatably connected to the machine base 1, a rotating shaft 10 coaxially fixedly connected to the turntable 9, a support frame 11 installed on the machine base 1, a roll-changing rotating drive mechanism 12 installed on the support frame 11 and used to drive the rotating shaft 10 to rotate, a rotating sleeve 13 rotatably sleeved outside the rotating shaft 10, a transmission sleeve 14 rotatably sleeved on the rotating sleeve 13, a winding drive mechanism 15 and a winding drive mechanism 2 16 respectively installed on the support frame 11, a pulley assembly 17 transmission-connected between the winding drive mechanism 15 and the rotating sleeve 13, and a transmission sleeve 14 transmission-connected to the winding drive mechanism 15. The pulley assembly 2 18 between the winding drive mechanism 2 16 and the transmission sleeve 14 and the air expansion shaft 1 19, guide shaft 1 20, air expansion shaft 21 and guide shaft 2 22 which are respectively rotatably connected to the turntable 9, the air expansion shaft 19, guide shaft 1 20, air expansion shaft 21 and guide shaft 2 22 are distributed in a circular array around the central axis of the turntable 9, the machine base 1 is equipped with a cutting drive mechanism 23 for driving the clamping and cutting mechanism 8 to approach or move away from the air expansion shaft 19 or the air expansion shaft 21, the end of the air expansion shaft 19 is transmission-connected with the pulley assembly 3 24 and the air expansion shaft 21 is transmission-connected with the pulley assembly 4 25. Specifically, the pulley assembly 1 17, the pulley assembly 2 18, the pulley assembly 3 24 and the pulley assembly 4 25 are all composed of synchronous belts and synchronous wheels; the roll-changing rotation drive mechanism 12, the winding drive mechanism 1 15 and the winding drive mechanism 2 16 can all use motors; the cutting drive mechanism 23 can be composed of a cylinder and a rocker arm, or a motor, which will not be repeated here.

[0030] In practical applications, two paper tubes with double-sided adhesive on the outer walls are respectively mounted on the air expansion shaft 19 and the air expansion shaft 21. At this time, the air expansion shaft 19 is in the receiving position of the machine base 1 (such as Figure 3As shown in the figure, the air expansion shaft 21 is at the position of the machine base 1 to be connected to the material, and the material strip is pasted on the paper tube of the air expansion shaft 19. The winding drive mechanism 15 drives the rotating sleeve 13 to rotate via the pulley assembly 17, and the rotating sleeve 13 drives the air expansion shaft 19 to rotate via the pulley assembly 3 24, and the paper tube on the rotating air expansion shaft 19 winds up the material strip. When the diameter of the material strip rolled up by the paper tube on the air expansion shaft 19 reaches the preset diameter, the roll-changing rotating drive mechanism 12 drives the rotating shaft 10 to rotate together with the turntable 9 to adjust the positions of the air expansion shaft 19 and the air expansion shaft 21, and the guide shaft 10 guides the material strip. Then the cutting drive mechanism 23 drives the pressing and cutting mechanism 8 to approach the air expansion shaft 21, so that the pressing and cutting mechanism 8 presses the material strip and pastes it on the paper tube of the air expansion shaft 21. At the same time, the pressing and cutting mechanism 8 connects the paper tube of the air expansion shaft 21 to the air expansion shaft 21. The material strip between the paper tube of the cylinder and the air expansion shaft 19 is cut off, and the winding drive mechanism 16 drives the transmission sleeve 14 to rotate via the pulley assembly 18, and the rotating transmission sleeve 14 drives the air expansion shaft 21 to rotate via the pulley assembly 4 25, and the paper tube on the rotating air expansion shaft 21 rewinds the material strip; the winding drive mechanism 15 stops working, which is convenient for the operator to replace the paper tube on the air expansion shaft 19, and repeats the above actions, and the air expansion shaft 19 and the air expansion shaft 21 cooperate to rewind the material alternately, thereby realizing non-stop rewinding. Since the rotating shaft 10, the rotating sleeve 13 and the transmission sleeve 14 are rotated and sleeved together in sequence, the winding drive mechanism 15 and the winding drive mechanism 2 16 can be installed on the support frame 11, and there is no need to rotate synchronously with the turntable 9, which reduces the driving burden of the roll-changing rotating drive mechanism 12.

[0031] In this embodiment, the pressing and cutting mechanism 8 includes a rotating frame 26, a pressing swing frame 27, a cutting swing frame 28, a pressure roller 29, a cutting knife 30, a pressing cylinder 31 and a cutting cylinder 32.

One end of the pressing swing frame 27 is rotatably connected to the rotating frame 26, and the pressure roller 29 is rotatably connected to the other end of the pressing swing frame 27. One end of the pressing cylinder 31 is hinged to the rotating frame 26, and the other end of the pressing cylinder 31 is hinged to the pressing swing frame 27. The middle part is hinged, one end of the cutting swing frame 28 is rotatably connected to the rotating frame 26, the cutting knife 30 is installed at the other end of the cutting swing frame 28, the pressing swing frame 27 is located in the cutting swing frame 28, one end of the cutting cylinder 32 is hinged to the rotating frame 26, the other end of the cutting cylinder 32 is hinged to the middle part of the cutting swing frame 28, the pressure roller 29 is located on the inner side of the cutting knife 30, the pressure roller 29 is used to press the material strip onto the air expansion shaft 19 or the air expansion shaft 21, and the cutting knife 30 is used to cut the material strip between the air expansion shaft 19 and the air expansion shaft 21.

[0032] In actual application, when it is necessary to change the roll, the turntable 9 rotates to adjust the position of the air expansion shaft 19 and the air expansion shaft 21, and the cutting drive mechanism 23 first drives the rotating frame 26 of the pressing and cutting mechanism 8 to rotate close to the corresponding air expansion shaft (air expansion shaft 19 or air expansion shaft 21), so that the pressure roller 29 and the cutting knife 30 first approach the material belt, and then the piston rod of the pressing cylinder 31 extends and pushes the pressing swing frame 27 to swing together with the pressing roller 29 close to the material belt until the pressing roller 29 presses the material belt and sticks it to the paper tube of the corresponding air expansion shaft, and then the piston rod of the cutting cylinder 32 extends and pushes the cutting swing frame 28 to swing together with the cutting knife 30 close to the material belt until the cutting knife 30 cuts the material belt between the air expansion shaft 19 and the air expansion shaft 21. Compared with the prior art in which the material strip is pressed and pasted and the material strip is cut at the same time, the pressing and cutting mechanism 8 first presses and pastes the material strip onto the paper tube of the corresponding air-expanding shaft through the pressing roller 29, and then cuts the material strip, which has good working stability and good quality of cutting the material strip.

Before the cutting knife 30 cuts the material tape, the support belt end of the support belt anti-loosening mechanism 34 supports the material tape on the rolled up material tape to ensure that the rolled up material tape will not loosen.

[0035] In this embodiment, the belt anti-loosening mechanism 34 includes a rotating rod 35 rotatably connected to the machine base 1, a swing arm 36 fixedly connected to one end of the rotating rod 35, a belt roller 37 rotatably connected to the swing arm 36, a connecting rod 38 installed at the other end of the rotating rod 35, and a belt cylinder 39 arranged on the machine base 1, the piston rod of the belt cylinder 39 is hinged to the end of the connecting rod 38 away from the rotating rod 35, and the belt roller 37 is arranged corresponding to the air expansion shaft 19 or the air expansion shaft 21.

[0036] In this embodiment, the slitting mechanism 2 includes a mounting rod 40 mounted on the machine base 1, a knife seat 41 mounted on the mounting rod 40, and a slitting knife 42 mounted on the knife seat 41. The slitting knife 42 is arranged corresponding to one of the middle guide rollers 5. When the material passes through the gap between the slitting knife 42 and the corresponding middle guide roller 5, the slitting knife 42 slits the material to form two material strips.

[0037] In this embodiment, the knife holder 41 is slidably connected to the mounting rod 40, and the knife holder 41 is locked on the mounting rod 40 via a locking piece 43; specifically, the locking piece 43 can be a bolt. In actual application, the locking piece 43 is loosened, and the knife holder 41 can slide along the length of the mounting rod 40 to adjust the position of the knife holder 41, thereby adjusting the cutting position of the slitting knife 42 to meet the needs of different cutting of materials.

In actual application, the slit material strip passes through the traction gap, and the rotation driver 46 drives the driving roller 45 to rotate. The rotating driving roller 45 cooperates with the driven roller 44 to drive the slit material strip to move.

[0039] In this embodiment, the machine base 1 is equipped with a roll diameter detector, and the roll diameter detector is electrically connected to the roll changing rotation drive mechanism 12; in actual application, the roll diameter detector detects the roll diameter of the material strip after winding, and when the roll diameter of the material strip after winding reaches the preset roll diameter size, the roll diameter detector feeds back a signal to the roll changing rotation drive mechanism 12, so that the roll changing rotation drive mechanism 12 works, and the air expansion shaft 19 and the air expansion shaft 2 21 exchange positions to realize roll changing and winding without stopping the machine.
