[0041] Reference Figure 1-Figure 8 According to an embodiment of the present invention, an uninterrupted paper roll slitting machine with automatic loading and unloading functions includes a winding device 101, an unwinding device 102 and a slitting mechanism 103. The paper roll is first unwound by the unwinding device 102, then slit by the slitting mechanism 103, and finally rewound by the winding device 101.

[0042] In this embodiment, the unwinding device 102 includes two right brackets 11 distributed front and back, a right mounting plate 12 is hinged on the right bracket 11, and two right support arms 13 symmetrically distributed front and back are slidably connected on the right side surface of the right mounting plate 12, a support head 14 is installed on the right support arm 13, and a No. 5 motor 15 is installed on the right support arm 13 for driving the support head 14 to rotate for unwinding, and also includes a raw material lifting mechanism for controlling the angle of the right mounting plate 12 and the front and rear position of the right support arm 13.

[0043] Specifically, the material lifting mechanism includes a No. 3 cylinder 16 hinged in the right bracket 11, and the end of the piston rod in the No. 3 cylinder 16 is hinged to the left side of the right mounting plate 12. The staff can control the angle of the right mounting plate 12 by controlling the No. 3 cylinder 16;

[0044] In addition, two No. 4 cylinders 17 are installed in the right mounting plate 12, and the two No. 4 cylinders 17 are staggered up and down and distributed front to back. The two piston rods in the two No. 4 cylinders 17 are respectively connected to the two right support arms 13, and the staff can control the front and rear positions and relative distances of the two right support arms 13 through the No. 4 cylinders 17.

[0045] The specific loading process of the unwinding device 102 is as follows:

[0046] First, the staff places the raw paper roll between the two right support arms 13, and then adjusts the position of the right support arm 13 forward and backward to insert the two support heads 14 into the raw paper roll. Then the staff adjusts the angle of the right mounting plate 12 through the No. 3 cylinder 16, so that the support head 14 supports the raw paper roll and lifts it. After that, the support head 14 can be driven to rotate by the No. 5 motor 15, so that the raw paper roll can be unwound.

[0047] In addition, it also includes a feeding mechanism, which includes a bottom frame 21, in which a load-bearing shaft 22 distributed in a left and right array is rotatably connected, an active plate 23 is slidably connected to the bottom frame 21, and a No. 1 motor (not shown in the figure) is installed in the right bracket 11 for driving the active plate 23 to move left and right. Specifically, an open groove is provided in the bottom frame 21, the output shaft in the No. 1 motor is connected to a threaded shaft extending into the open groove, and the threaded shaft is threadedly connected to the driving plate of the active plate 23 extending into the open groove, and the right side of the active plate 23 is hinged with two cross plates 24 distributed front and back, and a passive rod 25 is also provided between the two cross plates 24.

[0048] The specific feeding process is that when the unwinding device 102 is unwinding, the staff moves the active plate 23 to the right, and puts the hingedly installed cross plate 24 and the passive rod 25 on the outside of the spare raw material paper roll located on the right side of the bottom frame 21. Then the bottom frame 21 moves to the left so that the spare raw material paper roll can be pushed onto the bearing shaft 22 through the inclined surface in the bottom frame 21. In addition, the passive rod 25 can be replaced by a rotating roller to further reduce friction.

[0049] In addition, two inclined rods inclined to the upper left are provided on the active plate 23. When the spare raw paper roll is dragged onto the bearing shaft 22, the two inclined rods are respectively close to the front and rear sides of the lower edge of the paper tube in the raw paper roll in the unwinding device 102. When the paper on the paper roll in the unwinding device 102 is exhausted, the two right support arms 13 move away from each other. During this process, the paper tube originally sleeved outside the two support heads 14 will abut against the inclined rods and detach from the support heads 14. Then, the active plate 23 continues to move to the left and continues to drag the spare raw paper roll to the left so that it can be clamped and lifted by the support heads 14. After the original spare raw paper roll is clamped and lifted by the support heads 14, the active plate 23 can reset to the right and drag another raw paper roll to the bearing shaft 22, and this cycle is repeated.

[0050] In the second embodiment of the feeding mechanism, in order to make it unnecessary for the staff to pass the paper roll through various roller groups again when replacing the raw paper roll, a welding mechanism is also included. The winding device 101 and the unwinding device 102 are connected by a connecting frame 71. The welding mechanism includes a slide bar 72 slidably connected to the connecting frame 71. A fixed plate 73 is installed on the slide bar 72. A lifting ultrasonic welding machine is installed in the fixed plate 73. The working principle of the ultrasonic welding machine is the existing technology. It is briefly described that the head therein can move up and down and perform ultrasonic welding operations, which will not be repeated here.

[0051] The right mounting plate 12 is slidably connected to a bottom plate 74, a curved rod 75 is fixed to the bottom plate 74, and the bottom plate 74 is connected to the slide bar 72 through a longitudinal rod 76. The connecting frame 71 is also provided with a No. 1 cylinder (not shown in the figure) for controlling the left and right position of the slide bar 72.

[0052] The left side of the fixed plate 73 is slidably connected with a lifting plate 78, and the lifting plate 78 is connected to the head of the ultrasonic welding machine through a connecting block, and the lifting plate 78 is provided with a pre-clamping mechanism that acts on the paper and is loose or tight according to the up and down positions. In addition, an extension plate 41 is fixedly provided on the right side of the slide rod 72, and a short shaft 79 is slidably connected to each of the two extension plates 41 in a forward and backward manner, and the lifting plate 78 is equipped with a No. 2 cylinder 80 for controlling the forward and backward positions of the short shaft 79.

[0053] Specific welding process:

[0054] When the unwinding device 102 performs unwinding operation, the spare raw material paper roll is placed in the bottom frame 21, and the staff winds the paper in the spare raw material paper roll around the short shaft 79 and makes it stick to the lower edge of the head in the ultrasonic welding machine, and then makes the end of the paper be clamped by the pre-clamping mechanism. When the paper roll in the unwinding device 102 is unwound and the spare raw material paper roll is clamped and loaded through the feeding mechanism, the head in the ultrasonic welding machine moves downward, and presses the paper clamped by the pre-clamping mechanism onto the paper that is originally in the transmission state on the arc rod 75, and performs ultrasonic welding operation;

[0055] When the head moves downward, the No. 1 cylinder drives the slide bar 72 to move leftward, so that the fixed plate 73, the bottom plate 74 and the arc rod 75 move leftward. The speed of the arc rod 75 moving leftward is the same as the speed of the paper conveying after the speed reduction during the loading process, that is, the paper and the arc rod 75 remain relatively still during the welding operation;

[0056] Furthermore, when the machine head moves downward and abuts against the arc rod 75, the pre-clamping mechanism can automatically release the clamped paper, and the No. 2 cylinder 80 controls the short shaft 79 to retract, so that the paper in the spare raw material paper roll can be automatically tightened and returned to its position after the spare raw material paper roll is clamped by the support head 14.

[0057] After welding is completed, the machine head is reset upward, and the slide bar 72 is reset to the right. The function of the short shaft 79 is to avoid friction between the papers when the welding operation is not performed.

[0058] In one embodiment of the pre-clamping mechanism, the pre-clamping mechanism includes a No. 2 motor 81 installed on the left side of the lifting plate 78, and the output shaft extending from the No. 2 motor 81 is connected to a drive shaft 82, and two opposite threads are processed on the drive shaft 82. Two sliders 83 are connected to the lower side of the lifting plate 78 for sliding back and forth, and the two sliders 83 are respectively connected to the two threads in the drive shaft 82, and a pressure plate 84 is respectively installed on the sides of the two sliders 83 that are close to each other.

[0059] When the lifting plate 78 moves downward to the lowest side following the machine head, the No. 2 motor 81 is energized and causes the drive shaft 82 to rotate. At this time, the two sliders 83 move away from each other, and the paper roll pressed on the lifting plate 78 by the pressing plate 84 can automatically detach to avoid interfering with the transmission of paper after welding. After the lifting plate 78 moves upward, the pressing plates 84 can approach each other and reset, and the pressing plates 84 have a certain elasticity, so that the staff can press the paper roll on the lower side of the lifting plate 78 through the pressing plate 84.

[0060] The winding device 101 includes two left brackets 51 distributed front and back, two middle rods distributed left and right are fixedly arranged between the left brackets 51, and two left support arms 53 distributed front and back symmetrically are rotatably connected to the outside of each middle rod, and a driving cylinder 57 is rotatably connected inside the left support arm 53 located on the front side, and a support rod 54 is fixed at the rear end of the driving cylinder 57, and also includes a No. 3 motor (not shown in the figure) for driving the driving cylinder 57 to rotate, and a No. 5 cylinder 55 is installed on the left support arm 53 located on the rear side, and a slide cylinder is arranged on the piston rod in the No. 5 cylinder 55, and a rotating cylinder 56 is rotatably connected to the rear end of the support rod 54, and the rotating cylinder 56 can be inserted into or detached from the sliding cylinder to realize the clutch between the left support arm 53 and the support rod 54 located on the rear side.

[0061] In addition, a No. 6 cylinder 59 is hinged on the left bracket 51, and the piston rod extending from the No. 6 cylinder 59 is hinged to the left support arm 53, so that each left support arm 53 can be controlled independently. The staff can control the angle of the left support arm 53 and the support rod 54 through the No. 6 cylinder 59.

[0062] In addition, in order to realize the automatic loading and unloading of the paper roll and the reel on the support rod 54, a sleeve 60 is fixedly provided on the left support arm 53 at the front side, and the sleeve 60 is rotatably connected to the outside of the middle rod and supported by the middle rod. A left mounting plate 61 is fixedly provided on the sleeve 60, and each of the left mounting plates 61 is equipped with a push-pull arm;

[0063] In this embodiment, the push-pull arm includes a base 62 slidably connected to the left mounting plate 61, and two locking plates 63 are installed on the base 62, which are distributed front and back. A V-shaped swing arm 64 is connected between the two locking plates 63 through a No. 1 rotating shaft, and an extension arm 65 extending to the outside of the locking plates 63 is connected between the locking plates 63 through a No. 2 rotating shaft. A No. 7 cylinder 66 is also hinged on the locking plate 63, and a piston rod in the No. 7 cylinder 66 is hinged to one end of the swing arm 64, and a connecting rod 67 is hinged to the other end of the swing arm 64, and an end of the connecting rod 67 away from the swing arm 64 is hinged to the extension arm 65, and a support plate 68 is provided on the extension arm 65;

[0064] The left mounting plate 61 is provided with a No. 4 motor (not shown in the figure) for controlling the forward and backward movement of the base 62 .

[0065] In addition, two material preparation bins 70 are fixedly disposed on the left bracket 51 at the rear side, and rolls are arranged in the upper and lower parts of the cavities in the material preparation bins 70. The material preparation bins 70 are located at the rear side of the left support arm 53.

[0066] A discharge port is provided in the front side of the material preparation bin 70, and the discharge port is on the swing trajectory of the support rod 54. A No. 8 cylinder 18 is also provided on the material preparation bin 70, and a push plate is provided in the cavity. The piston rod in the No. 8 cylinder 18 is connected to the push plate.

[0067] The push-pull arm has two functions: one is to push the paper roll outside the support rod 54 away from the support rod 54;

[0068] The second is to use friction to drag the reel pushed from the material preparation bin 70 to the outside of the support rod 54 into place.

[0069] The specific loading and unloading process of the winding device 101 is as follows:

[0070] When the winding is completed, the staff cuts the paper and the equipment slows down, then the left support arm 53 swings downward so that the paper roll on it touches the ground, then the No. 5 cylinder 55 controls the rotating drum 56 to leave the slide, then only the left support arm 53 on the rear side is lifted, and then the push-pull arm can stick to the edge of the inner roll of the outer paper roll of the support rod 54 and push it away from the support rod 54 (backward).

[0071] When there is no longer a paper roll outside the support rod 54, the left support arm 53 on the front side swings upward and makes the support rod 54 face the discharge port in the material preparation bin 70, and makes the left support arm 53 on the rear side swing downward to avoid interference, and then the No. 8 cylinder 18 on the material preparation bin 70 corresponding to the left and right positions of the support rod 54 works to push out the roll located at the bottom layer in the material preparation bin 70 and put it on the outside of the support rod 54, and then the support plate 68 sticks to the outside of the roll and drags it to the appropriate front and rear positions on the support rod 54 through friction, and then the front and rear left support arms 53 are adjusted to the same angle, and the slide is again put on the outside of the rotating drum 56, and the staff can wind the paper roll around the roll outside the support rod 54 again, and make the uninterrupted paper roll slitting machine with automatic loading and unloading function resume the slitting speed, and at this time, the loading and unloading work at the winding device 101 is completed once.

[0072] In this embodiment, the slitting mechanism 103 is integrated between the left bracket 51, specifically, a plurality of No. 1 conveying shafts 31 are rotatably connected between the right bracket 11, at least one of the No. 1 conveying shafts 31 is located on the lower side of the arc rod 75, a plurality of No. 2 conveying shafts 32 distributed on the left and right are rotatably connected between the connecting frame 71, a No. 3 conveying shaft 33 and a slitting shaft 35 are also rotatably connected between the left bracket 51, and a staggered shaft 34 distributed on the left and right is also rotatably connected between the left bracket 51, and the slitting mechanism 103 includes a slitting knife 36 mounted on the left bracket 51 through a mounting frame, the slitting knife 36 extends into the annular groove in the slitting shaft 35, and the paper passes through the No. 1 conveying shaft 31, the No. 2 conveying shaft 32 and the No. 3 conveying shaft 35, and moves downward and is slid by the slitting knife 36, and then the front and back staggered paper will pass through the staggered grooves 34 on both sides and be wound around the reels outside the two left and right support rods 54.
