One end of the guide rod 20 passes through the screw nut and is fixedly connected to one side of the negative pressure bellows 14. A sleeve 10 is rotatably installed on the outside of the screw nut. One end of the sleeve 10 is fixedly connected to the surface of one side of the driving gear 11. The surface of one side of the driving gear 11 is fixedly connected to an annular plate 12 through a connecting rod. The annular plate 12 is sleeved on the light rod 15 and is slidably connected to the light rod 15. One side surface of the annular plate 12 intermittently abuts against one end of the air storage bag 6; a light rod 15 is provided on one end of the transmission screw 27. The sliding part, the sliding sleeve on the smooth part is provided with a limit plate 26, and one side surface of the limit plate 26 is fixedly connected to the negative pressure bellows 14 through a spring; the guide assembly includes two guide wheels 3 arranged up and down, the guide wheels 3 are fixedly provided with a rubber sleeve 4, and the shafts of the two guide wheels 3 are rotatably mounted on the fixed frame 2, and the shafts of the two groups of guide assemblies are connected by a transmission belt, and one end of the shaft of any group of guide assemblies passes through the fixed frame 2 and is fixedly installed with a driven gear 13, and the two driven gears 13 are meshed and connected, and the driven gear 13 is intermittently meshed and connected with the driving gear 11; During operation, the drive motor 9 can be used to rotate in the reverse direction, so that the transmission screw 27 and the light rod 15 rotate synchronously. At this time, the screw nut moves from right to left, and the rotation of the light rod 15 can drive the driving gear 11 to rotate synchronously. When the screw nut moves, the sleeve 10 can drive the driving gear 11 to move synchronously, so that the driving gear 11 can move linearly while rotating, so that the driving drive is engaged with any driven gear 13. At the same time, the screw nut stops moving when it moves to the smooth part, and squeezes the limit plate 26 and the spring at the same time; when the drive motor 9 rotates forward, the spring gives a thrust to the limit plate 26 and the screw nut, so that the screw nut can move in the reverse direction; When the driving gear 11 is meshed with the driven gear 13, the glass tube can be placed between the upper and lower guide wheels 3. At this time, the two driven gears 13 can rotate synchronously, and the rotation of the driven gear 13 can drive the shaft of the guide assembly to rotate, thereby rotating the guide wheel 3. The glass tube is transported by the rotation of the guide wheel 3. At the same time, the rubber sleeve 4 can buffer and protect the glass tube, effectively buffering the extrusion force applied by the guide wheel 3 to the glass tube, thereby ensuring the stability of the glass tube transportation, thereby realizing automatic loading and facilitating continuous cutting. Example

[0020] like Figure 3 , Figure 5 and Figure 7As shown, a fixed cavity column 22 is fixedly installed on the inner wall of one side of the cutting sleeve 5, a piston plate 23 is arranged inside the fixed cavity column 22, the bottom end of the piston plate 23 is fixedly connected to the bottom end of the fixed cavity column 22 through a spring, a piston rod 25 is fixedly installed on the upper end of the piston plate 23, one end of the piston rod 25 extends to the outside of the fixed cavity column 22 and is fixedly connected to the cutter 21; an annular air bag 28 is installed on the inner wall of the cutting sleeve 5, an air storage bag 6 is sleeved on the outer wall of the cutting sleeve 5, both ends of the air storage bag 6 are connected to reset springs 19, one side of the air storage bag 6 is connected to an air supply pipe 24, one end of the air supply pipe 24 is connected to the inside of the annular air bag 28, and one side of the air supply pipe 24 is connected to the inside of its fixed cavity column 22 through a pipeline; When the driving motor 9 rotates forward, the screw nut can be moved toward the cutting sleeve 5 and the driving gear 11 can be pushed to move synchronously. The driving gear 11 can rotate and move while pushing the annular plate 12 to move synchronously, and the annular plate 12 can squeeze the air storage bag 6, so that the reset spring 19 is compressed, and then the gas inside the air storage bag 6 is squeezed out and part of the gas is sent into the annular air bag 28 through the gas pipe 24. At the same time, another part of the gas enters the fixed cavity column 22, so that the air pressure inside the fixed cavity column 22 increases and pushes the piston plate 23 to move upward, so that the cutter 21 moves upward and abuts against the outer wall of the glass tube. When the driving gear 11 contacts the teeth 8, the cutting sleeve 5 can be engaged to rotate, and the circumferential surface of the glass tube can be cut by the cutter 21 inside the cutting sleeve 5. The operation is simple, such as Figure 1 and Figure 2 As shown, the width of the tooth 8 is greater than the width of the driving gear 11, which can ensure that the driving gear 11 is always engaged with the tooth 8 during the movement of one end of the driving gear 11; The air pressure inside the annular airbag 28 increases and expands to approach the outer wall of the glass tube but does not contact the outer wall of the glass tube, so that one end of the cutting sleeve 5 can be blocked during cutting to prevent glass slag from splashing to the outside; At the same time, when the cutting is completed, the driving gear 11 moves in the opposite direction following the screw nut. At this time, the reset spring 19 pushes the air storage bag 6 to reset, thereby sucking out the gas inside the annular air bag 28 and the fixed cavity column 22, causing the annular air bag 28 to shrink. At the same time, the cutter 21 shrinks, which can prevent the cutter 21 from scratching the glass tube, thereby effectively protecting the glass tube. Example

[0021] like Figure 3 and Figure 5 As shown, a fan blade 16 is provided in the negative pressure wind box 14, and the fan blade 16 is fixedly mounted on the output shaft of the driving motor 9. A negative pressure air duct is connected to the upper end of the negative pressure wind box 14, and one end of the negative pressure air duct is communicated with the annular cavity provided inside the fixing seat 7. A negative pressure cavity is provided inside the cutting sleeve 5, and the negative pressure cavity is communicated with the inside of the annular cavity. A negative pressure dust suction hole 17 is provided on the inner wall of the cutting sleeve 5, and the negative pressure dust suction hole 17 is communicated with the inside of the negative pressure cavity. During operation, the fan blades 16 can be driven to rotate when the drive rotates, so that the fan blades 16 can be used to discharge the air flow inside the negative pressure bellows 14, and negative pressure is generated inside the negative pressure air duct, and then the negative pressure adsorption work is performed on the annular cavity and the inside of the negative pressure cavity through the negative pressure air duct, so that the negative pressure cavity can absorb the small glass slag generated by cutting in the cutting sleeve 5 through a plurality of negative pressure holes, so as to avoid the phenomenon of slag splashing during cutting; Figure 3 As shown, a filter is provided inside the negative pressure bellows 14, which can be used to filter the absorbed airflow, leaving the glass slag inside, and discharge the airflow through an opening on one side of the negative pressure bellows 14 and blow it toward the drive motor 9 to dissipate heat from the drive motor 9.

[0022] Working principle: During the working process, the driving motor 9 can be used to rotate in the reverse direction, so that the transmission screw 27 and the light rod 15 rotate synchronously. At this time, the screw nut moves from right to left, and the rotation of the light rod 15 can drive the driving gear 11 to rotate synchronously. When the screw nut moves, the sleeve 10 can drive the driving gear 11 to move synchronously, so that the driving gear 11 can move linearly while rotating, so that the driving drive is engaged with any driven gear 13. At the same time, the screw nut stops moving when it moves to the smooth part, and squeezes the limit plate 26 and the spring at the same time; when the driving motor 9 rotates forward, the spring gives a thrust to the limit plate 26 and the screw nut, so that the screw nut can move in the reverse direction; When the driving gear 11 is meshed with the driven gear 13, the glass tube can be placed between the upper and lower guide wheels 3. At this time, the two driven gears 13 can rotate synchronously, and the driven gear 13 can drive the shaft of the guide assembly to rotate while rotating, so that the guide wheel 3 can rotate, and the glass tube can be transported by the rotation of the guide wheel 3. At the same time, the rubber sleeve 4 can buffer and protect the glass tube, effectively buffer the extrusion force applied by the guide wheel 3 to the glass tube, and ensure the stability of the glass tube transportation, so as to realize automatic loading and facilitate continuous cutting. When the driving motor 9 rotates forward, the screw nut can be moved toward the cutting sleeve 5 and the driving gear 11 can be pushed to move synchronously. The driving gear 11 can rotate and move while pushing the annular plate 12 to move synchronously, and the annular plate 12 can squeeze the air storage bag 6, so that the reset spring 19 is compressed, and then the gas inside the air storage bag 6 is squeezed out and part of the gas is sent into the annular air bag 28 through the gas pipe 24. At the same time, another part of the gas enters the fixed cavity column 22, so that the air pressure inside the fixed cavity column 22 increases and pushes the piston plate 23 to move upward, so that the cutter 21 moves upward and abuts against the outer wall of the glass tube. When the driving gear 11 contacts the teeth 8, the cutting sleeve 5 can be engaged to rotate, and the circumferential surface of the glass tube can be cut by the cutter 21 inside the cutting sleeve 5. The operation is simple, such as Figure 1 and Figure 2 As shown, the width of the tooth 8 is greater than the width of the driving gear 11, which can ensure that the driving gear 11 is always engaged with the tooth 8 during the movement of one end of the driving gear 11; The air pressure inside the annular airbag 28 increases and expands to approach the outer wall of the glass tube but does not contact the outer wall of the glass tube, so that one end of the cutting sleeve 5 can be blocked during cutting to prevent glass slag from splashing to the outside; At the same time, when the cutting is completed, the driving gear 11 moves in the reverse direction following the screw nut, and the reset spring 19 pushes the air storage bag 6 to reset, thereby sucking out the gas inside the annular air bag 28 and the fixed cavity column 22, so that the annular air bag 28 shrinks, and the cutter 21 shrinks at the same time, which can prevent the cutter 21 from scratching the glass tube, effectively protecting the glass tube; When the drive rotates, the fan blades 16 are driven to rotate, so that the fan blades 16 can be used to discharge the airflow inside the negative pressure bellows 14, and negative pressure is generated inside the negative pressure air duct, and then the negative pressure adsorption work is performed on the annular cavity and the inside of the negative pressure cavity through the negative pressure air duct, so that the negative pressure cavity can absorb the broken glass slag generated by cutting in the cutting sleeve 5 through multiple negative pressure holes, so as to avoid the phenomenon of broken slag splashing during cutting; like Figure 3 As shown, a filter is provided inside the negative pressure bellows 14, which can be used to filter the absorbed airflow, leaving the glass slag inside, and discharge the airflow through an opening on one side of the negative pressure bellows 14 and blow it toward the drive motor 9 to dissipate heat from the drive motor 9.
