[0015] As a preferred solution of the automatic production line for cigarette tube processing of the present invention, wherein: The clamping unit also includes a mobile power source, which is fixedly connected to the top of the connecting plate, and the bottom of the mobile power source is transmission-connected to the moving platform through a screw rod, and a connecting arm extends outward from the surface of the moving platform; The surface of the connecting arm is fixedly connected to a clamping frame, the surface of the clamping frame is fixedly connected to a clamping power source, the output shaft of the clamping power source passes through the clamping frame and is transmission-connected to the active member, the interior of the clamping frame is rotationally connected to two clamping jaws, the parts of the two clamping jaws arranged inside the clamping frame are fixedly connected to a driven member, the two clamping jaws are transmission-connected through the driven member, and the side portion of any of the driven members is rotationally engaged with the active member.

[0016] Beneficial effects of the present invention: When the lifting plate is lifted, the plurality of clamping column heads on the side of the blocking section will move to the surface of the blocking section under the lifting of the plurality of vertical plates, and then the plurality of clamping column heads will be in contact with the surface of the blocking section under the contact of the plurality of clamping column heads with the surface of the blocking section.

[0017] Second, move the displacement table downward again, so that the displacement table drives the expansion head to approach the inside of the expansion section, and finally insert the expansion head into the inside of the expansion section, so that the width profile of the expansion head squeezes the expansion section to expand outward, so that the expansion head pushes the expansion section and the sleeve module to contact, so that the expansion section is closed and squeezed by the expansion head and the sleeve module to form an expansion, thereby increasing the diameter of the expansion section opening, which is convenient for subsequent assembly.

[0018] 3. Start the processing power source, and make it drive the circular turntable to rotate. The rotation of the circular turntable will drive the movable disk at its bottom to rotate accordingly. Under the action of the grease pre-applied to the opposite surfaces of the expansion head and the sleeve module, the expansion head and the sleeve module rotate relative to the clamped smoke tube fitting following the circular turntable. During the lubricating rotation, the expansion head and the sleeve module rotate and smooth the expanded tube section, thereby avoiding excessive stress on a certain part of the expanded tube section, thereby reducing local deformation or irregular expansion of the smoke tube fitting during the expansion process, thereby making the expansion more uniform.

[0019] Fourth, the rotation of the movable disk will drive the docking joint inserted into it to rotate through the docking interface, and the rotation of the docking joint is driven by the vertical plate, so that the clamping plate rotates relative to the bearing plate through the rotating member 2, and the ring plate connected to the vertical plate through the extension plate rotates relative to the output shaft of the lifting member 1, so that when multiple clamping plates follow the rotation of the movable disk, the multiple clamping column heads on the top will roll on the surface of the plugging section during the rotation of the clamping plate, so that the clamping column heads squeeze the inner wall of the plugging section to fit the surface of the pipe plug during rolling, so that the gap between the two is reduced, which helps to improve the sealing performance between the two and ensure that there will be no leakage at the joint after welding. The unevenness of the opening of the plugging section and its surface will also be relatively rolled flat, thereby reducing the gap and unevenness during welding, and helping to stabilize the metal molten pool during welding, reduce the occurrence of welding defects such as pores and cracks, and improve the strength and quality of the welded joint.

[0020] 5. After the circular turntable drives the movable disk to rotate for a preset time, the sealing section is smoothly attached to the surface of the pipe plug, and then the laser welding head is started to rotate with the circular turntable, so that the laser welding head performs rotational welding on the connection between the top of the pipe plug and the inner wall of the sealing section, thereby reducing the external welding of the pipe plug and the sealing section in the prior art through internal welding, so that there is a gap directly between the top of the pipe plug and the inner wall of the sealing section. Therefore, under the frequent flushing of flue gas, part of the flue gas that has not been discharged through the drilling section will rush into the gap between the pipe plug and the sealing section, aggravating the connection fatigue degree of the pipe plug and the sealing section. The internal welding of the sealing section and the pipe plug reduces the contact of the gap between the sealing section and the pipe plug with respect to the flue gas, and the gap between the sealing section and the pipe plug is rolled and compressed during the rotation of the clamping column head, thereby further improving the connection strength between the pipe plug and the sealing section.

[0021] 6. In the process of rolling the clamping column head relative to the blocking section, the middle part of the smoke tube, i.e. the clamping section, is clamped by the clamping claws, and the top of the smoke tube is lubricated and clamped by the expansion head and the sleeve module, so that the smoke tube is fixed in multiple places, and the clamping column head rolls the blocking section and the pipe plug relative to each other, thereby reducing the axial runout of the smoke tube when the clamping column head is leveling the surface of the blocking section, thereby facilitating the laser welding head to weld the blocking section and the pipe plug more stably.

For the continuity of processing, a punching mechanism can be added to the path of the transmission chain 105. After the transmission chain 105 moves to the punching mechanism position and stops, the drill bit inside the punching mechanism punches the surface of the cigarette tube 4 to form a drilling section 402.

[0037] When the transmission chain 105 drives the cigarette pipe 4 clamped by the clamp 2042 to move to the middle position of the back plate 302, the central axis of the clamping section 401 is now in line with the central axis of the mounting column 3093 and the central axis of the raised seat 30311, and the top of the raised seat 30311 is placed with the pipe plug 405 in advance manually or by a robot, so that the protrusion on the top of the raised seat 30311 is pressed against the groove at the bottom of the pipe plug 405 to achieve preliminary fixation. In this process, the lifting of the raised seat 30311 will drive the clamping plate 305 on its side to rise synchronously, so that when the pipe plug 405 is pushed into the interior of the sealing section 403, the clamping column head 307 is located on the outside of the surface of the sealing section 403, thereby achieving the corresponding positioning of the sealing section 403 to the clamping column head 307.

[0038] Lubricating grease is applied to the opposite surfaces of the sleeve module 3091 and the expansion head 3082 in advance, and the docking power source 3021 is started, so that the docking power source 3021 drives the rotating part 3021 to rotate, and the rotating part 30211 drives the displacement platform 3022 to move downward, so that the middle opening 3095 in the middle of the movable disk 309 is sleeved onto the surface of the smoke pipe part 4, and the mounting column 3093 and the laser welding head 3094 pass through the expansion section 404 and the clamping section 401 to reach the connection between the drilling section 402 and the blocking section 403, so that the sleeve module 3091 is closed and sleeved onto the surface of the clamping section 401 under the push of the closing power source 30911, and at this time, the expansion head 3082 has not yet contacted the expansion section 404.

[0039] Then, the lifting member 3031 is started, so that the output shaft of the lifting member 3031 drives the raised seat 30311 and the pipe plug 405 to approach the inside of the blocking section 403, and finally the pipe plug 405 enters the inside of the blocking section 403, thereby completing the blocking preparation of the pipe plug 405 for the blocking section 403; Then, the lifting member 2 3032 is started, and the output shaft of the lifting member 2 3032 pushes the extension plate 3061 and the vertical plate 3062 to rise, so that the collar plate 306 on the side of the extension plate 3061 rises along the output shaft of the lifting member 1 3031, and finally the trigger section 30621 on the surface of the vertical plate 3062 contacts the linkage member 1 30541, so that the trigger section 30621 drives the linkage member 1 30541 to rotate during the process of the vertical plate 3062 being lifted, so that when the linkage member 1 30541 rotates, it drives the linkage member 2 30542 to rotate through the rotating shaft in the middle thereof, so that when the linkage member 2 30542 rotates, it drives the moving plate 3052 to move toward the sealing member along the docking groove 30511 inside the clamping plate 305 The blocking section 403 approaches, and finally, during the lifting of the vertical plate 3062, the linkage member 1 30541 drives the linkage member 2 30542 to rotate, and the linkage member 2 30542 drives the movable plate 3052 and the clamping column head 307 on the top thereof to approach the blocking section 403, and finally, the clamping column head 307 presses the blocking section 403 to fit the surface of the blocking section 403. At this time, the vertical plate 3062 stops moving, and during the lifting of the collar plate 306, the multiple clamping column heads 307 on the side of the blocking section 403 will move to the surface of the blocking section 403 under the lifting of the multiple vertical plates 3062, and then under the contact between the multiple clamping column heads 307 and the surface of the blocking section 403, the blocking section 403 is clamped by relative movable contact; When the vertical plate 3062 is lifted, the docking joint 30623 on its top will be inserted into the interior of the docking port 3092, thereby completing the linkage docking between the docking port 3092 and the docking joint 30623, and in the subsequent lifting of the vertical plate 3062, the top of the vertical plate 3062 that is not in contact with the docking joint 30623 will drive the movable disk 309 to rise along the limiting rod 3083, so that when the vertical plate 3062 is lifted, that is, after the clamping column head 307 contacts the surface of the blocking section 403, the top surface of the sleeve module 3091 on the top of the movable disk 309 is flush with the top surface of the expansion tube section 404.

[0040] Continue to move the displacement table 3022 downward, so that the displacement table 3022 drives the expansion head 3082 to approach the interior of the expansion section 404, and finally the expansion head 3082 is inserted into the interior of the expansion section 404, so that the width profile of the expansion head 3082 squeezes the expansion section 404 to expand outward, so that the expansion head 3082 pushes the expansion section 404 and the sleeve module 3091 to contact, so that the expansion section 404 is closed and squeezed by the expansion head 3082 and the sleeve module 3091 to form an expansion, so that the diameter of the opening of the expansion section 404 is increased, so as to facilitate subsequent assembly. At this time, the laser welding head 3094 descends to the connection between the top surface of the pipe plug 405 and the plugging section 403. For the accuracy of welding, a camera can be installed on the side of the laser welding head 3094. By feeding back the welding distance and position information collected by the camera and comparing it with the preset distance and position information, the size and length of the laser welding beam can be controlled.

[0041] The processing power source 308 is started, and the processing power source 308 drives the circular rotating disk 3081 to rotate. The rotation of the circular rotating disk 3081 drives the movable disk 309 at the bottom thereof to rotate accordingly. Under the effect of the grease pre-applied to the opposite surfaces of the expansion head 3082 and the sleeve module 3091, the expansion head 3082 and the sleeve module 3091 rotate relative to the clamped smoke pipe 4 following the circular rotating disk 3081, so that during the lubricating rotation, the expansion head 3082 and the sleeve module 3091 rotate relative to the expanded pipe section 404. Rotation and leveling are performed to avoid excessive stress on a certain part of the expansion section 404, thereby reducing local deformation or irregular expansion of the smoke tube 4 during the expansion process, so that the expansion is more uniform. Of course, in order to improve the efficiency of rotation, the expansion head 3082 can also be lifted a short distance so that there is a gap between the bottom of the expansion head 3082 and the sleeve module 3091, so that the sides of the expansion head 3082 and the sleeve module 3091 are still in relative contact with the smoke tube 4 under the action of the lubricating oil.

[0042] Of course, an alternative design can also be made to set the expansion head 3082 and the sleeve module 3091 to a two-layer structure with inner and outer layers, with balls embedded between the inner and outer layers, so that the outer layer of the expansion head 3082 and the sleeve module 3091 rotates relative to the inner layer, so that the rotation of the circular turntable 3081 will not excessively drive the inner layer of the expansion head 3082 and the sleeve module 3091 to rotate.

[0043] The rotation of the movable disk 309 drives the docking joint 30623 inserted into it to rotate through the docking interface 3092, and the rotation of the docking joint 30623 is driven by the vertical plate 3062 to make the clamping plate 305 rotate relative to the carrier plate 304 through the rotating member 2 3041, and the collar plate 306 connected to the vertical plate 3062 through the extension plate 3061 rotates relative to the output shaft of the lifting member 1 3031, so that when the multiple clamping plates 305 follow the rotation of the movable disk 309, the multiple clamping column heads 307 on the top thereof will rotate during the rotation of the clamping plate 305. The surface of the plugging section 403 rolls, so that the clamping column head 307 squeezes the inner wall of the plugging section 403 to fit the surface of the pipe plug 405 during rolling, so that the gap between the two is reduced, which helps to improve the sealing performance between the two, and ensures that there will be no leakage at the joint after welding. The unevenness of the opening of the plugging section 403 and its surface will also be relatively rolled and flattened, thereby reducing the gap and unevenness during welding, and helping to stabilize the metal molten pool during the welding process, reducing the occurrence of welding defects such as pores and cracks, and improving the strength and quality of the welded joint; After the rotating disk 3081 drives the movable disk 309 to rotate for a preset time, the plugging section 403 is flatly attached to the surface of the pipe plug 405, and then the laser welding head 3094 is started to rotate with the rotating disk 3081, so that the laser welding head 3094 performs rotational welding on the connection between the top of the pipe plug 405 and the inner wall of the plugging section 403, thereby reducing the external welding of the pipe plug 405 and the plugging section 403 in the prior art through internal welding, so that there is a gap directly between the top of the pipe plug 405 and the inner wall of the plugging section 403, thereby Under the frequent flushing of the gas, part of the flue gas that has not been discharged through the drilling section 402 will rush into the gap between the pipe plug 405 and the sealing section 403, aggravating the connection fatigue of the pipe plug 405 and the sealing section 403, and the internal welding of the sealing section 403 and the pipe plug 405 reduces the contact of the gap between the sealing section 403 and the pipe plug 405 with the flue gas, and the gap between the sealing section 403 and the pipe plug 405 is rolled and compressed during the rotation of the clamping column head 307, thereby further improving the connection strength between the pipe plug 405 and the sealing section 403.

[0044] And in the process of rolling the clamping column head 307 relative to the blocking section 403, the middle part of the smoke tube component 4, namely the clamping section 401, is clamped by the clamping claw 2042, and the top of the smoke tube component 4 is lubricated and clamped by the expansion head 3082 and the sleeve module 3091, so that the smoke tube component 4 is fixed in multiple places, and the clamping column head 307 rolls the blocking section 403 and the pipe plug 405 relative to each other, thereby reducing the axial runout of the smoke tube component 4 in the process of leveling the surface of the blocking section 403 by the clamping column head 307, thereby facilitating the laser welding head 3094 to weld the blocking section 403 and the pipe plug 405 more stably.

[0045] When welding is completed, the closed power source 3091 drives the sleeve module 3091 to reset, so that the displacement table 3022 is reset and the lifting member 3031 and the back plate 302 are reset, so that the smoke tube component 4 is exposed from the middle opening 3095, and the clamping claw 2042 drives the clamped smoke tube component 4 to continue to move along with the transmission chain 105 that was originally stopped waiting for welding, so that the transmission chain 105 transfers the processed smoke tube component 4 to the next process.
