Then, the controller 102 is used to simultaneously start the three second servo electric cylinders 112. At this time, the three started second servo electric cylinders 112 will all drive the corresponding rectangular blocks 113 to move horizontally with the cooperation of the mounting plate 111, and the three rectangular blocks 113 that move horizontally will all drive the corresponding anti-skid pads 117 to move horizontally. When the three anti-skid pads 117 are in contact with the outer walls of the corresponding paper tubes 3 (such as Figure 1As shown), at this time, the controller 102 is first used to close the three second servo electric cylinders 112. At this time, the three closed second servo electric cylinders 112 will stop the corresponding anti-skid pads 117 from moving. Then, the T-shaped rod 115 is removed. Then, the controller 102 is used to start the first servo electric cylinder 106. At this time, one end of the telescopic end of the started first servo electric cylinder 106 will pass through the inside of the three paper tubes 3 in sequence. When the telescopic end of the started first servo electric cylinder 106 moves to a point where it can no longer move, at this time, one end of the telescopic end of the first servo electric cylinder 106 is just completely inside the cylindrical groove 114. At the same time, the controller 102 is used to close the first servo electric cylinder 106, and then the T-shaped rod 115 is reset to its original position. At this time, the T-shaped rod 115 The bottom end just passes through the inside of the cylindrical hole 116, and then the controller 102 is used to start the first servo electric cylinder 106. At this time, the started first servo electric cylinder 106 will drive the tube-piercing shaft 104 to move horizontally under the cooperation of the mounting frame 105, the placement frame 103, the cylindrical groove 114, the cylindrical hole 116 and the T-shaped rod 115. When the end face of the tube-piercing shaft 104 close to the mounting frame 105 and the side of the fixed platform 109 close to the mounting frame 105 are in the same plane, the tube-piercing shaft 104 just passes through the inside of the three paper tubes 3 in sequence. At the same time, the controller 102 is used to close the first servo electric cylinder 106. At this time, the closed first servo electric cylinder 106 will stop the tube-piercing shaft 104 from moving, and then the T-shaped rod 115 is removed. At this time, the T-shaped The bottom end of the rod 115 just moves out from the inside of the cylindrical hole 116, and then the controller 102 is used to continue to start the first servo electric cylinder 106. When one end of the telescopic end of the first servo electric cylinder 106 is completely moved out from the inside of the cylindrical groove 114, the first servo electric cylinder 106 is directly closed by the controller 102, and then the three second servo electric cylinders 112 are started by the controller 102. At this time, the three started second servo electric cylinders 112 will all drive the corresponding anti-skid pads 117 to reset and move with the cooperation of the corresponding rectangular blocks 113. When the three anti-skid pads 117 are reset to their original positions, the three second servo electric cylinders 112 are directly closed by the controller 102, and then the tube-piercing shaft 104 passing through the three paper tubes 3 is removed. That is, the automatic tube threading operation is completed. When another paper tube 3 of a larger size needs to be threaded, the three paper tubes 3 that need to be threaded are first operated according to the above operation steps, and are all placed between the fixed platform 109 and the movable platform 110. Then, the first electric push rod 209 is started by the controller 102. At this time, the started first electric push rod 209 will drive the movable platform 110 to move on the top of the cabinet 101 with the cooperation of the installation groove 207 and the rectangular hole 208. At this time, the movable movable platform 110 will drive the two round rods 210 to move. At the same time, the movable movable platform 110 will drive the three rectangular plates 212 to move with the cooperation of the three rectangular grooves 211. When the movable platform 110 moves to the appropriate position,At this time, the two sides of each paper tube 3 are respectively in contact with the two sides of the inner wall of each groove of the fixed platform 109 and the two sides of the inner wall of each groove of the movable platform 110, and the first electric push rod 209 is closed by the controller 102. At this time, the closed first electric push rod 209 will stop the movable platform 110 from moving, and the stopped movable platform 110 will stop the two round rods 210 and the three rectangular plates 212 from moving. Then, the three second servo electric cylinders 112 are started simultaneously by the controller 102 until the three anti-slip pads 117 are respectively in contact with the outer walls of the three paper tubes 3, and then the hand-tightening bolts 108 are removed, and then the cabinet door 107 is opened, and then the tube-threading shaft 104 of suitable size placed inside the cabinet 101 is taken out, and the above operation is followed. The step is to place the tube-threading shaft 104 on the placement rack 103, then close the cabinet door 107, and then reset the hand-tightening bolt 108 to its original position, and finally use the controller 102 to simultaneously start the two second electric push rods 215. At this time, the two started second electric push rods 215 will drive the placement rack 103 to move with the cooperation of the cabinet body 101, and the moving placement rack 103 will drive the tube-threading shaft 104 to move. When the placement rack 103 moves to a suitable position, the controller 102 is directly used to close the two second electric push rods 215. At this time, the two closed second electric push rods 215 will stop the tube-threading shaft 104 from moving with the cooperation of the placement rack 103, and at the same time, the cross-sectional center of the tube-threading shaft 104 is just aligned with the cross-sectional center of the three paper tubes 3. The centers of the cross-section circles are on the same straight line, and then the controller 102 is used to start the third electric push rod 217. At this time, the started third electric push rod 217 will drive the mounting frame 105 to move horizontally under the cooperation of the auxiliary plate 216, the cabinet 101, the two slide grooves 213 and the two sliders 214, and the mounting frame 105 that moves horizontally will drive the first servo electric cylinder 106 to move horizontally. When the first servo electric cylinder 106 moves horizontally to a suitable position, the controller 102 is directly used to close the third electric push rod 217. At this time, the closed third electric push rod 217 will stop the first servo electric cylinder 106 from moving horizontally. Then, the controller 102 is used to start the motor 201. At this time, the started motor 201 will move between the cabinet 101 and L With the cooperation of the L-shaped plate 203, the rotating rod 202 is driven to rotate, and the rotating rotating rod 202 drives the two gears 206 to rotate. At the same time, the two rotating gears 206 drive the corresponding racks 205 to move vertically upward with the cooperation of the L-shaped plate 203, the cabinet 101 and the corresponding U-shaped block 204. The two racks 205 that move vertically upward will drive the mounting frame 105 to move vertically upward with the cooperation of the corresponding slide groove 213 and the corresponding slider 214. At the same time, the mounting frame 105 that moves vertically upward will drive the auxiliary plate 216 to move vertically upward with the cooperation of the third electric push rod 217, and the mounting frame 105 that moves vertically upward will also drive the first servo electric cylinder 106 to move vertically upward.When the first servo electric cylinder 106 moves vertically upward to a suitable position, the controller 102 is directly used to turn off the motor 201. The turned-off motor 201 will stop the first servo electric cylinder 106 from moving vertically upward. At the same time, the center of the end face of the telescopic end of the first servo electric cylinder 106 is just in the same straight line with the center of the cross section of the three paper tubes 3. Then, the above operation steps are followed to complete the threading operation of the paper tube 3 of another size.
