It is noted here that the fan 42 is reversely installed. When the fan 42 is turned on, the waste on the surface of the workbench 1 will be automatically sucked into the inside of the collection box 41 by negative pressure extraction. Here Due to the provision of the protective filter 43, waste chips will be isolated outside the protective filter 43. As the amount of waste chips accumulates, part of the waste chips will automatically fall into the dust box 47 through the through groove 44 under the action of gravity. When the waste chips inside the dust box 47 need to be cleaned, at this time, it is only necessary to pull the dust box 47 out from the inside of the support bar 45 to the horizontal side. During installation, it is only necessary to adjust the limiting T-shaped bar 48 to the appropriate position and then engage it into the limiting T-shaped slot 46 at the corresponding position.

When the paper tube conflicts with the conflicting tooth pad 58 during the sleeve setting process, the conflicting tooth pad 58 is automatically driven by the conflicting force to move the annular conflicting plate 57 to the side. When the annular conflicting plate 57 moves, it will automatically drive the limiting piston rod 55 to slide inside the limiting sleeve 54. At this time, the conflicting spring 56 is in a contracted state due to the squeezing effect of the limiting piston rod 55. At the same time, the conflicting spring 56 is squeezed and synchronously generates a reaction force to drive the limiting piston rod 55 to move in the opposite direction, thereby pushing the annular conflicting plate 57 to move. When the annular conflicting plate 57 moves, it will automatically push the conflicting tooth pad 58 to fit the outer wall of the paper tube. When the paper tube needs to be rotated during processing, it only needs to turn on the driving motor 51. When the driving motor 51 is turned on, it will automatically drive the rotating shaft to rotate and then drive the supporting disk 52 to rotate. Subsequently, the rotation of the supporting disk 52 will automatically drive the supporting roller 3 to rotate and then drive the paper tube to rotate.

[0025] The auxiliary moving mechanism 6 includes a positioning box 61, a control motor 62, a reciprocating screw rod 63 and an auxiliary strip 64. The top outer wall of the workbench 1 is provided with a positioning box 61, and the side inner wall of the positioning box 61 is provided with a control motor 62. The control motor 62 is connected to one end of the reciprocating screw rod 63, and the other end of the reciprocating screw rod 63 is rotatably installed with the side inner wall of the positioning box 61. The side of the reciprocating screw rod 63 is provided with an auxiliary strip 64 in parallel, and both ends of the auxiliary strip 64 are connected to the side inner wall of the positioning box 61. The outside of the reciprocating screw rod 63 and the auxiliary strip 64 is provided with a limiting protrusion 65, and the outer walls on both sides of the limiting protrusion 65 are slidably installed with the side inner wall of the positioning box 61. The protruding end of the limiting protrusion 65 is connected to the bottom outer wall of the U-shaped support block 66, and the U-shaped support block 66 is connected to the positioning box 61. The top outer wall is slidably installed; when it is necessary to control the position of the cutting blade 710 in order to control the cutting length of the paper tube, it is necessary to first turn on the control motor 62. When the control motor 62 is turned on, it will automatically drive the reciprocating screw 63 to rotate and then drive the limiting protrusion 65 to rotate. Here, due to the setting of the auxiliary strip 64, the reciprocating screw 63 will only drive the limiting protrusion 65 to realize the sliding trajectory movement in the horizontal direction when rotating, and then the movement of the limiting protrusion 65 will automatically drive the U-shaped support block 66 to move. When the U-shaped support block 66 moves, it will automatically drive the cutting blade 710 to move. When the cutting blade 710 moves to the appropriate position, the control motor 62 can be turned off. It is noted here that the control motor 62 has a self-locking function. After being turned off, the U-shaped support block 66 can still maintain the unchanged position after moving.

[0026] Auxiliary blocks 71 are symmetrically arranged on the top outer wall of the U-shaped support block 66, a control shaft 72 is connected between the two auxiliary blocks 71, a support column 73 is rotatably installed on the outside of the control shaft 72, a mounting block 74 is arranged on the outer wall on one side of the top of the support column 73, a support cylinder 75 is arranged on the outer wall on the other side of the top of the support column 73, the mounting block 74 is rotatably installed inside the support member 76, the side outer wall of the support member 76 is connected to the output end of the electric push rod 77, the electric push rod 77 is connected to the side outer wall of the support back plate 78, the support back plate 78 is connected to the top outer wall of the U-shaped support block 66, a micro motor 79 is arranged on the side inner wall of the support cylinder 75, the micro motor 79 is connected to one end of the rotating shaft, and the other end of the micro motor 79 passes through the side outer wall of the support cylinder 75 and is connected to the cutting blade 710; when the cutting When the blade 710 moves to the appropriate position and needs to cut the paper tube, it is necessary to start the micro motor 79 and the electric push rod 77 synchronously. When the micro motor 79 is turned on, it will automatically drive the rotating shaft to rotate and then drive the cutting blade 710 to rotate. The setting of the support tube 75 here has the effect of limiting support for the micro motor 79. When the electric push rod 77 is turned on, it will automatically push the support member 76 to move. Then the movement of the support member 76 will automatically drive the mounting block 74 to move. When the mounting block 74 moves, it will automatically drive the support column 73 to move. At this time, the support column 73 uses the control shaft 72 as the rotating support shaft to make an offset trajectory movement. The setting of the auxiliary block 71 here has the effect of limiting support for the control shaft 72. Then the deviation of the support column 73 will automatically drive the support tube 75 to deviate, so that the cutting blade 710 cuts the paper tube.

[0027] When the utility model is in use, the paper tube needs to be positioned outside the support roller 3 before processing. At this time, the paper tube needs to be sleeved onto the outside of the support roller 3. When the paper tube conflicts with the conflicting tooth pad 58 during the sleeve setting process, the conflicting tooth pad 58 automatically drives the annular conflicting plate 57 to move to the side due to the conflicting force. When the annular conflicting plate 57 moves, it automatically drives the limiting piston rod 55 to slide inside the limiting sleeve 54. At this time, the conflicting spring 56 is in a contracted state due to the squeezing effect of the limiting piston rod 55. At the same time, the conflicting spring 56 is squeezed and generates a reaction force to drive the limiting piston rod 55 to move in the opposite direction, thereby pushing the annular conflicting plate 57 to move. When the touch plate 57 moves, it will automatically push the abutment tooth pad 58 to fit the outer wall of the paper tube. When the paper tube needs to be rotated during processing, it only needs to turn on the drive motor 51. When the drive motor 51 is turned on, it will automatically drive the rotating shaft to rotate and then drive the support plate 52 to rotate. Then, the rotation of the support plate 52 will automatically drive the support roller 3 to rotate and then drive the paper tube to rotate; when it is necessary to control the position of the cutting blade 710 in order to control the cutting length of the paper tube, it is necessary to turn on the control motor 62 first. When the control motor 62 is turned on, it will automatically drive the reciprocating screw 63 to rotate and then drive the limit protrusion 65 to rotate. Here, due to the setting of the auxiliary strip 64 When the reciprocating screw rod 63 rotates, it will only drive the limiting protrusion 65 to realize the sliding track movement in the horizontal direction, and then the movement of the limiting protrusion 65 will automatically drive the U-shaped support block 66 to move. When the U-shaped support block 66 moves, it will automatically drive the cutting blade 710 to move. When the cutting blade 710 moves to a suitable position, the control motor 62 can be turned off. It is noted that the control motor 62 has a self-locking function. After being turned off, the U-shaped support block 66 can still maintain the unchanged position after the movement; when the cutting blade 710 moves to a suitable position and needs to cut the paper tube, the micro motor 79 and the electric push rod 77 need to be turned on synchronously. When the micro motor 79 is turned on, It will automatically drive the rotating shaft to rotate and then drive the cutting blade 710 to rotate. The setting of the support cylinder 75 here plays a role of limiting support for the micro motor 79. When the electric push rod 77 is turned on, it will automatically push the support member 76 to move. Then the movement of the support member 76 will automatically drive the installation block 74 to move. When the installation block 74 moves, it will automatically drive the support column 73 to move. At this time, the support column 73 uses the control shaft 72 as the rotating support shaft to make an offset trajectory movement. The setting of the auxiliary block 71 here plays a role of limiting support for the control shaft 72. Then the deviation of the support column 73 will automatically drive the support cylinder 75 to deviate, so that the cutting blade 710 cuts the paper tube;

[0028] When it is necessary to collect and clean the paper tube cutting waste accumulated on the outer wall of the workbench 1, it is necessary to turn on the fan 42 first. It is noted here that the fan 42 is installed in reverse. When the fan 42 is turned on, the waste on the surface of the workbench 1 will be automatically sucked into the collection box 41 by negative pressure extraction. Here, due to the setting of the protective filter 43, the waste will be isolated outside the protective filter 43. As the amount of waste accumulates more and more, part of the waste will automatically fall into the dust box 47 through the through groove 44 under the action of gravity. When it is necessary to clean the waste inside the dust box 47, it is only necessary to pull the dust box 47 out from the inside of the support bar 45 to the horizontal side. During installation, it is only necessary to adjust the limiting T-shaped bar 48 to the appropriate position and then snap it into the limiting T-shaped slot 46 at the corresponding position.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
