Description

Technical Field

[0001] This utility model belongs to the technical field of slitting and rewinding machines, specifically relating to a fully automatic paper tube double half-shaft rewinding device. Background Technology

[0002] In the paper processing industry, the rewinding process is a crucial step in rolling slit paper into standard paper rolls. Traditional rewinding equipment generally suffers from low automation, frequent manual intervention, and low production efficiency in the paper tube feeding, sorting, and rewinding processes. Specifically, this manifests in the following ways:

[0003] 1. Traditional rewinding equipment typically requires manual handling to move paper tubes one by one to the straightening platform, and then manually adjust the axial alignment and radial limit of the paper tubes. Taking a regular slitting and rewinding machine as an example, a single production line requires 2-3 workers per hour to be responsible for feeding paper tubes. This not only results in high labor costs, but manual straightening is also prone to causing deviations in the position of the paper tubes (such as axial misalignment exceeding 1mm), which in turn causes uneven paper tension during rewinding, resulting in quality defects such as wrinkles and eccentricity.

[0004] 2. Traditional slitting and rewinding machines mostly use a single-shaft air-expansion structure, requiring manual placement of the paper tube onto the air-expansion shaft, followed by manual control of inflation via a valve. After the paper roll is wound up, manual deflation and disassembly are also necessary, taking approximately 2-3 minutes per cycle. For high-speed rewinding production lines (speed ≥ 300 m / min), frequent manual intervention severely restricts production capacity. Furthermore, repeated disassembly and reassembly of the air-expansion shaft can lead to wear on the seals, increasing equipment maintenance costs.

[0005] 3. In traditional equipment, the paper tube handling, conveying, feeding, and rewinding processes are independent and lack automated linkage control. During the conveying process from the temporary storage bin to the slitting and rewinding machine, paper tubes require manual handling or simple belt conveyor transport. This often leads to conveyor jams due to paper tube accumulation, causing downtime and impacting production capacity. Furthermore, the manual coordination of each step makes precise timing control difficult, resulting in significant idling time for the slitting and rewinding machine.

[0006] In summary, existing rewinding technologies have significant shortcomings in terms of automation continuity, labor cost control, and production efficiency. There is an urgent need to achieve fully automated operation of paper tube feeding, sorting, and rewinding through modular automation design, in order to reduce labor costs, increase production capacity, and ensure product quality consistency. Utility Model Content

[0007] To address the above problems, the purpose of this utility model is to provide a fully automatic paper tube double half-shaft rewinding device, which solves the problems of low automation, excessive manual intervention, low production efficiency, high cost and poor coordination of multiple processes in traditional rewinding equipment during paper tube feeding, sorting and rewinding processes, making it difficult to meet the production needs of high efficiency and cost reduction.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic paper tube double half-shaft rewinding device, comprising a paper tube aligning mechanism, a paper tube conveying platform, a paper tube aligning platform, a paper tube feeding platform, and a slitting and rewinding machine. The paper tube conveying platform is located behind the paper tube aligning mechanism. The paper tube conveying platform includes a support frame, on which a gear and rack slide module is mounted. A hook assembly is mounted on the slide seat of the gear and rack slide module. The paper tube feeding platform is mounted on the slitting and rewinding machine. The paper tube feeding platform includes a crossbeam, on which a through-type lead screw motor is mounted. One end of the lead screw in the through-type lead screw motor is connected to a sliding table. A multi-segment copper sleeve slide rail is connected between the sliding table and the crossbeam. The paper tube aligning platform includes a platform base. The base is mounted on the slide of the linear guide rail one. The guide rail of the linear guide rail one is mounted on the sliding table, and the guide rail of the linear guide rail one is flush with the guide rail of the gear and rack slide module. The platform base is equipped with a V-shaped bracket, an axial alignment component, a secondary positioning mechanism, and a radial limiting mechanism. The hook component in the paper tube conveying platform pulls and connects to the platform base. The slitting and rewinding machine includes a frame. The frame is equipped with an active roller. Half-shaft lifting mechanisms are installed on both sides of the frame of the active roller. The half-shaft lifting mechanisms drive and connect to a double half-shaft telescopic platform. The frame below the double half-shaft telescopic platform is equipped with an origin positioning mechanism. Half-shafts are installed on the two double half-shaft telescopic platforms and are arranged opposite to each other. The half-shafts are connected to a solenoid valve, a pressure transmitter, and a check valve.

[0009] The beneficial effects of this utility model are as follows: through the continuous operation of the paper management assembly mechanism, paper tube conveying platform, paper management assembly platform, paper tube feeding platform, and slitting and rewinding machine, automated paper management assembly and handling, air shaft tube insertion, automatic air filling and deflating, and tube unloading operations are realized, which greatly improves production efficiency and reduces labor costs; the modular double half-shaft design allows the conventional mobile rewinding mandrel in the industry to be directly fixed on the slitting and rewinding machine, effectively reducing the amount of manual labor.

[0010] In order to achieve efficient paper tube handling;

[0011] As a further improvement to the above technical solution: the paper tube assembly includes a temporary storage compartment, on which a drive mechanism, a guide assembly, and a stop assembly are installed. The drive mechanism drives and connects to a push plate. The top of the temporary storage compartment is provided with a stepped groove structure that gradually increases from front to back. Multiple partitions are installed at intervals along the axial direction of the paper tube in the stepped groove. The push plate is slidably inserted into the stepped groove. The top surface of the push plate is formed with progressively increasing protrusions from front to back, and the protrusions are provided with through slots for slidingly engaging partitions. The drive mechanism includes a motor, which is mounted on a safety frame. The safety frame is mounted on the lower side of the temporary storage compartment. The output shaft of the motor is connected to one end of a rotating rod. The other end of the rotating rod is rotatably connected to one end of a rocker arm via a pin. The other end of the rocker arm is rotatably connected to the push plate via a pin.

[0012] The beneficial effects of this improvement are: the motor can drive the push plate to move up and down reciprocally through the linkage mechanism, thereby neatly and orderly conveying the paper tubes stored in the stepped groove upwards.

[0013] In order to stably feed the paper tube to the paper management platform;

[0014] As a further improvement to the above technical solution: the material blocking assembly includes an L-shaped bracket, which is installed on both sides of the top of the temporary storage bin. The top of the L-shaped bracket is rotatably connected to a baffle plate via a pin. The baffle plate is rotatably connected to one end of a second cylinder via a pin. The other end of the second cylinder is rotatably connected to the L-shaped bracket via a pin. The material guiding assembly includes a guide plate, which is located behind the temporary storage bin. One end of the guide plate is rotatably connected to the other end of the L-shaped bracket via a pin. The middle part of the guide plate is rotatably connected to one end of a first cylinder via a pin. The other end of the first cylinder is rotatably connected to the temporary storage bin via a pin. Proximity sensors are installed on the back of the temporary storage bins between adjacent partitions.

[0015] The beneficial effects of this improvement are as follows: when cylinder two retracts, the baffle can act as a material stopper. After the sensor detects that a paper tube is being conveyed to the top of the trough between adjacent baffles, cylinder two extends to release the paper tubes that are being straightened at the top of the trough. The paper tubes fall onto the paper straightening platform under the guidance of the guide plate to achieve automatic feeding.

[0016] In order to stably transport the entire paper management platform to the paper tube feeding platform;

[0017] As a further improvement to the above technical solution: the hook assembly includes a second motor, which is mounted on the motor moving seat of the gear and rack slide module. The second motor drives the lead screw in the lead screw slide through a belt transmission mechanism. The lead screw slide is mounted on the motor moving seat of the gear and rack slide module. A hook is fixed on the lead screw nut in the lead screw slide. The hook is bent into an L-shaped rod structure in the axial direction of the lead screw of the lead screw slide. The end of the slide facing the paper management platform is formed with a slot adapted to insert the hook.

[0018] The beneficial effects of this improvement are as follows: the motor in the gear rack slide module drives the gear to rotate, thereby making the gear mesh with the rack fixed on the bracket. When moving linearly with the guide rail in the gear rack slide module, the hook on the crossbeam can drive the paper management platform to move between the paper tube conveying platform and the paper tube feeding platform. Before the paper management platform is pushed forward by the paper tube feeding platform to the slitting and rewinding machine for feeding, the second motor can drive the lead screw slide to make the hook move horizontally and disengage from the crossbeam, thus avoiding structural interference.

[0019] To further straighten the paper tubes after they are fed to the paper tube straightening platform;

[0020] As a further improvement to the above technical solution: the radial limiting mechanism includes cylinder five, the cylinder body of cylinder five is mounted on the platform base, a rack is fixed on the piston rod of cylinder five, the rack is meshed with a gear, the gear is mounted on a connecting shaft, the connecting shaft is rotatably mounted on the platform base, multiple pressure plates are mounted on the connecting shaft, the axial alignment assembly is located at both ends of the platform base, the axial alignment assembly includes cylinder three, the cylinder body of cylinder three is fixed on the platform base, a connecting plate is fixed on the piston rod of cylinder three, the connecting plate is mounted on a chain pin of chain drive mechanism one, two sprockets in the connecting plate are rotatably mounted on the platform base, and stop bars are mounted on two chain pins of chain drive mechanism one, the stop bars are located on both sides of the V-shaped bracket.

[0021] The beneficial effects of this improvement are as follows: when the two cylinders extend, they drive the stop bar to move through the chain mechanism, thereby axially positioning the paper tube that falls in the V-shaped bracket. Then, cylinder five drives the pressure plate to rotate and press it on the paper tube through the gear mechanism, thereby radially limiting the paper tube and ensuring that the paper tube is fed in a regular manner.

[0022] In order to stably feed the paper tube into the slitting and rewinding machine;

[0023] As a further improvement to the above technical solution: the secondary positioning mechanism includes a cylinder four, the cylinder body of the cylinder four is mounted on the platform base, the piston rod of the cylinder four is connected to a guide rod, the guide rod slides through a limiting seat, the limiting seat is mounted on the platform base, a positioning plate is installed at the bottom of the guide rod, the bottom of the positioning plate is formed with a groove structure, and a protrusion that is adapted to and engages with the groove of the positioning plate is installed on the sliding table.

[0024] The beneficial effects of this improvement are as follows: when the paper management platform moves onto the crossbeam under the drive of the hook assembly, the cylinder drives the positioning plate to move down, so that the groove of the positioning plate engages with the protrusion installed on the sliding table, thereby stabilizing the position of the platform base in the axial direction of the paper tube before the through-type screw motor runs.

[0025] In order to stably transport the paper tubes on the paper management platform to the slitting and rewinding machine;

[0026] As a further improvement to the above technical solution: the motor in the through-type lead screw motor is mounted on the crossbeam; the multi-segment copper sleeve slide rail one includes three slide rails, each slide rail having an open-type copper sleeve slider slidably mounted on it; the slide rails are mounted on connecting seats, wherein a chain drive mechanism two is mounted on each of two adjacent connecting seats; two sprockets in the chain drive mechanism two are mounted on the connecting seats; connecting block one and connecting block two are connected to the chain of the chain drive mechanism two via pins; connecting block one is mounted on the open-type copper sleeve slider; connecting block two is mounted on the connecting seat; an open-type copper sleeve slider at one end of the multi-segment copper sleeve slide rail one is mounted on a sliding table; and a connecting seat at the other end of the multi-segment copper sleeve slide rail one is mounted on the crossbeam.

[0027] The beneficial effects of this improvement are: driven by a through-type lead screw motor, the multi-segment copper sleeve slide rail with a synchronous chain structure extends and retracts in the correct sequence, ensuring that the paper tube on the slide table is stably conveyed to the top of the drive roller.

[0028] In order to achieve automatic shaft mounting and dismounting of the half-shaft;

[0029] As a further improvement to the above technical solution: the dual half-shaft telescopic platform includes a base frame, on which a reduction motor is mounted and an output shaft is rotatably mounted. The reduction motor drives and connects to the output shaft. The output shaft is equipped with a drive sprocket of the chain drive mechanism three. The driven sprocket of the output shaft is rotatably mounted on the base frame. A half-shaft mounting bracket is mounted on the chain pin of the output shaft. A high-speed rotary joint is rotatably mounted on the half-shaft mounting bracket. The high-speed rotary joint is connected to one end of the half-shaft and connected to a compressed air pipeline. A multi-section copper sleeve slide rail two is connected between the half-shaft mounting bracket and the base frame. The multi-section copper sleeve slide rail two has the same structure as the multi-section copper sleeve slide rail one.

[0030] The beneficial effects of this improvement are as follows: When the geared motors in the two double half-shaft telescopic platforms are running, the two half-shafts are stably moved in the axial direction and inserted into the paper tube by the guidance of the chain mechanism and the multi-segment copper sleeve slide rail II. They are then connected to form a complete air expansion shaft for inflation, rotation and other operations. When the paper roll reaches the specified diameter, the air circuit system of the half-shaft automatically releases the air, and then the geared motor reverses to make the half-shaft exit the paper tube.

[0031] In order to ensure that the paper roll with gradually increasing diameter is stably driven to rotate by the drive roller during the paper roll winding process;

[0032] As a further improvement to the above technical solution: the number of active rollers is two and they are installed horizontally at intervals. The shaft of the active roller is driven by a drive motor. The half-shaft lifting mechanism includes a cylinder six. The cylinder body of the cylinder six is ​​mounted on the frame. The piston rod of the half-shaft lifting mechanism is connected to one end of a chain. The other end of the chain passes over a sprocket from top to bottom and is attached to the lifting frame. The sprocket is rotatably mounted on the frame. The double half-shaft telescopic platform is mounted on the lifting frame. A slide seat of the linear guide rail two is mounted on the surface of the lifting frame facing the frame. The guide rail of the linear guide rail two is mounted on the frame.

[0033] The beneficial effects of this improvement are as follows: with the cooperation of linear guide rail two and the pulling of cylinder six and chain, the double half-shaft telescopic platform and half-shaft can move up and down stably, so that the paper roll wound on the paper tube mounted on the half-shaft can be stably connected with the drive roller, thereby ensuring the stable rotation of the paper tube during the winding process.

[0034] In order to provide a stable input mechanical origin for the half-shaft during long-term operation of the equipment;

[0035] As a further improvement to the above technical solution: the origin positioning mechanism includes a cylinder seven, the cylinder body of the cylinder seven is rotatably connected to the frame via a pin, the piston rod of the cylinder seven is rotatably connected to a rotating rod via a pin, the middle end of the rotating rod is rotatably mounted on the frame via a pin, the other end of the rotating rod is located directly below the double half-shaft telescopic platform, and two proximity switches are installed on the frame, with the two proximity switches located on the upper and lower sides of the base frame respectively.

[0036] The beneficial effects of this improvement are as follows: After the paper management platform extends to its final position, the double-half-shaft telescopic platform moves higher than the paper management platform and stops at the upper limit proximity switch. The cylinder's seventh stroke is completed, causing the four rotating rods to form a support. The double-half-shaft telescopic platform then moves down to the support and stops after being detected by the lower limit proximity switch. After the two half-shafts are closed, the photoelectric sensor lights up, the controller receives a signal, and the double-half-shaft telescopic platform receives a signal. Driven by the half-shaft lifting mechanism, the entire platform moves to the upper limit proximity switch and stops. The controller receives a signal and controls the paper management platform to retract to the rearward origin. After receiving a signal, the double-half-shaft telescopic platform, carrying the paper tube, moves down between the two drive rollers and begins to wind the paper.

The paper tube feeding platform 4 is mounted on the slitting and rewinding machine 5. The paper tube feeding platform 4 includes a crossbeam 41, on which a through-type lead screw motor 42 is mounted. One end of the lead screw in the through-type lead screw motor 42 is connected to a sliding table 44. The sliding table 44 is connected to the crossbeam 41 by multiple segments. The paper tube conveying platform 3 includes a platform base 31, which is mounted on a slide of a linear guide rail 32.

The platform base 31 is equipped with a V-shaped bracket 33, an axial alignment component 34, a secondary positioning mechanism 35, and a radial limiting mechanism 36. The hook component 23 in the paper tube conveying platform 2 pulls and connects to the platform base 31. The slitting and rewinding machine 5 includes a frame 51, on which a drive roller 53 is mounted. Half-shaft lifting mechanisms 52 are mounted on both sides of the frame 51 of the drive roller 53. The drive is connected to a double-half-shaft telescopic platform 55. An origin positioning mechanism 54 is installed on the frame 51 below the double-half-shaft telescopic platform 55. Oppositely arranged half-shafts 56 are installed on the two double-half-shaft telescopic platforms 55. The half-shafts 56 are connected to a solenoid valve, a pressure transmitter, and a check valve.

The modular double-half-shaft design allows the conventional mobile rewinding mandrel to be directly fixed onto the slitting and rewinding machine, effectively reducing manual labor. The paper management assembly mechanism 1 includes... The device includes a temporary storage bin 11, on which a drive mechanism 14, a guide assembly 15, and a stop assembly 16 are installed. The drive mechanism 14 drives a push plate 13. The top of the temporary storage bin 11 has a stepped groove structure that gradually increases in height from front to back. Multiple partitions 12 are installed at intervals along the axial direction of the paper tube in the stepped groove. The push plate 13 is slidably inserted into the stepped groove. The top surface of the push plate 13 has protrusions with gradually increasing height formed at intervals from front to back, and the protrusions have through slots for slidingly engaging the partitions 12. The drive mechanism 14 includes a motor 141, which is mounted on a safety frame 144. The safety frame 144 is installed on the lower side of the temporary storage bin 11. The output shaft of the motor 141 is connected to one end of a rotating rod 142.The other end of the rotating rod 142 is rotatably connected to one end of the rocker arm 143 via a pin. The other end of the rocker arm 143 is rotatably connected to the push plate 13 via a pin. The motor 141 can drive the push plate 13 to move up and down reciprocally via a linkage mechanism, thereby neatly and orderly conveying the paper tubes stored in the stepped groove upwards. The material blocking assembly 16 includes an L-shaped bracket 161, which is installed on both sides of the top of the temporary storage bin 11.

Located behind the temporary storage bin 11, one end of the guide plate 152 is rotatably connected to the other end of the L-shaped bracket 161 via a pin. The middle part of the guide plate 152 is rotatably connected to one end of the cylinder 151 via a pin. The other end of the cylinder 151 is rotatably connected to the temporary storage bin 11 via a pin. Proximity sensors are installed on the back of the temporary storage bins 11 between adjacent partitions 12. When the cylinder 162 retracts, the baffle 163 can act as a material stopper. After the sensor detects that a paper tube is being conveyed to the top of the trough between adjacent partitions 12, the cylinder 162 extends to release the paper tubes arranged at the top of the trough. The paper tubes fall onto the paper tube arranging platform 3 under the guidance of the guide plate 152, realizing automatic feeding. The hook assembly 23 includes a second motor 2. 31. The second motor 231 is mounted on the motor moving seat of the gear rack slide module 22. The second motor 231 drives the lead screw in the lead screw slide 232 through a belt transmission mechanism. The lead screw slide 232 is mounted on the motor moving seat of the gear rack slide module 22. A hook 233 is fixed on the lead screw nut in the lead screw slide 232. The hook 233 is bent into an L-shaped rod structure in the axial direction of the lead screw in the lead screw slide 232. The sliding table 44 has a slot formed at the end facing the paper management platform 3 to accommodate the insertion of the hook 233. The motor in the gear rack slide module 22 drives the gear to rotate, thereby causing the gear to mesh with the rack fixed on the bracket 21, and cooperate with the guide rail in the gear rack slide module 22 to perform linear motion. During movement, the hook 233, which is attached to the crossbeam 41, can drive the paper tube conveying platform 3 to move between the paper tube conveying platform 2 and the paper tube loading platform 4. Before the paper tube loading platform 3 extends forward to the slitting and rewinding machine 5 for loading, the motor 231 can drive the lead screw slide 232 to make the hook 233 move horizontally and disengage from the crossbeam 41, avoiding structural interference. The radial limiting mechanism 36 includes a cylinder 361. The cylinder body of the cylinder 361 is mounted on the platform base 31. A rack 362 is fixed on the piston rod of the cylinder 361. The rack 362 is meshed with a gear 363. The gear 363 is mounted on a connecting shaft 364, which is rotatably mounted on the platform base 31.Multiple pressure plates 365 are mounted on the connecting shaft 364. The axial alignment assembly 34 is located at both ends of the platform base 31. The axial alignment assembly 34 includes a cylinder 341, the cylinder body of which is fixed to the platform base 31. A connecting plate 342 is fixed to the piston rod of the cylinder 341. The connecting plate 342 is mounted on a chain pin of a chain drive mechanism 343. Two sprockets in the connecting plate 342 are rotatably mounted on the platform base 31. A stop bar 344 is mounted on two chain pins of the chain drive mechanism 343. The stop bar 344 is located on both sides of the V-shaped bracket 33. When the two cylinders 341 extend, the stop bar 344 is driven to move through the chain mechanism, thereby axially aligning the cylinders. The paper tube, positioned axially in the V-shaped bracket 33, is then axially positioned by cylinder 361. Subsequently, cylinder 361 drives pressure plate 365 to rotate and press against the paper tube via a gear mechanism, radially limiting the paper tube and ensuring neat feeding. The secondary positioning mechanism 35 includes cylinder 351, whose cylinder body is mounted on platform base 31. The piston rod of cylinder 351 is connected to a guide rod 352, which slides through a limiting seat 353 mounted on platform base 31. A positioning plate 354 is mounted at the bottom of the guide rod 352, with a groove formed at its bottom. A protrusion on the sliding table 44 is fitted and engages with the groove of the positioning plate 354, ensuring the paper tube is leveled. When platform 3 moves onto crossbeam 41 under the drive of hook assembly 23, cylinder 4 351 drives positioning plate 354 to move downward, so that the groove of positioning plate 354 engages with the protrusion installed on sliding platform 44, thereby stabilizing the position of platform base 31 in the axial direction of paper tube before the through-type lead screw motor 42 runs. The motor in the through-type lead screw motor 42 is installed on crossbeam 41. The multi-segment copper sleeve slide rail 1 43 includes three slide rails 432, and each slide rail 432 has an open copper sleeve slider 431 slidably fitted on it. The slide rails 432 are installed on connecting seats 433, and each of the two adjacent connecting seats 433 is equipped with a chain drive mechanism 2 434. The two sprockets in the chain drive mechanism 2 434 are installed on the connecting seats 433. On seat 433, the chain of the second chain drive mechanism 434 is connected by a connecting block 435 and a connecting block 436 via a pin. The first connecting block 435 is mounted on an open-type copper sleeve slider 431, and the second connecting block 436 is mounted on a connecting seat 433. An open-type copper sleeve slider 431 located at one end of the multi-segment copper sleeve slide rail 43 is mounted on a sliding table 44, and a connecting seat 433 located at the other end of the multi-segment copper sleeve slide rail 43 is mounted on a crossbeam 41. Driven by a through-type lead screw motor 42, the multi-segment copper sleeve slide rail 43, using a synchronous chain structure, extends and retracts in the correct sequence to ensure that the paper tube on the sliding table 44 is stably conveyed to the top of the drive roller 53. The double half-shaft telescopic platform 55 includes a base frame 551.A geared motor 552 is mounted on the base frame 551, and an output shaft 553 is rotatably mounted thereon. The geared motor 552 drives the output shaft 553. A drive sprocket of a chain drive mechanism 554 is mounted on the output shaft 553. The driven sprocket of the output shaft 553 is rotatably mounted on the base frame 551. A half-shaft mounting bracket 555 is mounted on the chain pin of the output shaft 553. A high-speed rotary joint 556 is rotatably mounted on the half-shaft mounting bracket 555. The high-speed rotary joint 556 is connected to one end of the half-shaft 56 and connected to a compressed air pipeline. A multi-segment copper sleeve slide rail 557 is connected between the half-shaft mounting bracket 555 and the base frame 551. The multi-segment copper sleeve slide rail 557 and the multi-segment copper sleeve slide rail 557 are connected to the multi-segment copper sleeve slide rail 551. The structures of 43 are identical. When the reduction motors 552 in the two double-half-shaft telescopic platforms 55 operate, they guide the two half-shafts 56 to move stably in the axial direction and insert them into the paper tube via a chain mechanism and multi-segment copper sleeve slide rails 557. They then connect to form a complete air-expanding shaft for inflation, rotation, and other operations. When the paper roll reaches the specified diameter, the air system of the half-shaft 56 automatically deflates, and then the reduction motor 552 reverses to remove the half-shaft 56 from the paper tube. There are two drive rollers 53 installed horizontally at intervals. The shaft of each drive roller 53 is connected to a drive motor. The half-shaft lifting mechanism 52 includes a cylinder 521, the cylinder body of which is mounted on the frame 51. The piston rod of the half-shaft lifting mechanism 52 is connected to... One end of the chain 522 is connected to the other end, which passes over the sprocket 523 from top to bottom and is attached to the lifting frame 524. The sprocket 523 is rotatably mounted on the frame 51. The double half-shaft telescopic platform 55 is mounted on the lifting frame 524. A slide block in the linear guide rail 525 is mounted on the surface of the lifting frame 524 facing the frame 51. The guide rail in the linear guide rail 525 is mounted on the frame 51. With the cooperation of the linear guide rail 525 and the pulling of the cylinder 521 and the chain 522, the double half-shaft telescopic platform 55 and the half-shaft 56 can move stably up and down, so that the paper roll wound on the paper tube mounted on the half-shaft 56 can be stably connected to the drive roller 53, thereby ensuring the stability of the paper tube during the winding process. The origin positioning mechanism 54 includes a cylinder 541. The cylinder body of the cylinder 541 is rotatably connected to the frame 51 via a pin. The piston rod of the cylinder 541 is rotatably connected to a rotating rod 542 via a pin. The middle end of the rotating rod 542 is rotatably mounted on the frame 51 via a pin. The other end of the rotating rod 542 is located directly below the double half-shaft telescopic platform 55. Two proximity switches are installed on the frame 51, and the two proximity switches are located on the upper and lower sides of the base frame 551, respectively. After the paper management platform 3 extends forward to its position, the double half-shaft telescopic platform 55 is higher than the paper management platform 3 and moves upward to stop at the upper limit proximity switch. The stroke of the cylinder 541 is completed, so that the four rotating rods 542 form a support.The dual-semi-shaft telescopic platform 55 then moves down to the support and stops after being detected by the lower limit proximity switch. After the two semi-shafts 56 close, the photoelectric sensor illuminates, and the controller receives a signal. The controller then controls the dual-semi-shaft telescopic platform 55, which, driven by the semi-shaft lifting mechanism 52, moves to the upper limit proximity switch and stops. The controller receives a signal to control the paper tube to retract the entire platform 3 to its retracted origin. After receiving the signal, the dual-semi-shaft telescopic platform 55, carrying the paper tube, moves down between the two drive rollers 53 to begin winding the paper.

[0055] The working principle of this technical solution is as follows: Paper tubes are placed in batches into the temporary storage bin 11 of the paper tube consolidation mechanism 1. The stepped groove structure at the top of the temporary storage bin and the partition 12 form a multi-layer storage space. Motor 141 drives the push plate 13 to move up and down reciprocally through the rotating rod 142 and the rocker arm 143, so that the paper tubes move up and down step by step along the stepped groove until they are piled up to the top of the temporary storage bin. When the proximity sensor detects that the top of the groove between the adjacent partitions is full of paper tubes, cylinder 2 162 extends to drive the baffle 163 to flip open. Under the action of gravity, the paper tubes slide down along the guide plate 152 onto the V-shaped bracket 33 of the paper tube consolidation platform 3. The number of materials discharged at one time is precisely controlled by the spacing between the partitions.

[0056] After the paper tube falls into the V-shaped bracket 33, the cylinders 341 at both ends extend synchronously, driving the stop bar 344 to move towards the center through the chain drive mechanism 343 until the stop bar abuts against the end face of the paper tube, thus achieving axial position calibration; the piston rod of the cylinder 361 extends, and through the rack 362 and gear 363, the pressure plate 365 rotates and presses down onto the top surface of the paper tube, forming radial clamping to prevent the paper tube from rolling and deviating;

[0057] The gear and rack slide module 22 drives the hook assembly 23 to move to one side of the paper management platform 3. The motor 231 drives the hook 233 to insert into the slot of the platform base 31 through the lead screw slide 232. Then the gear and rack slide module 22 drives the hook assembly 23 to move in the opposite direction, pulling the paper management platform along the linear guide rail 32 to the crossbeam 41 of the paper tube feeding platform 4.

[0058] After the paper tube platform reaches the designated position on the crossbeam, cylinder 4 351 drives the light rod 352 to move down, so that the groove of the positioning plate 354 engages with the protrusion of the sliding table 44, ensuring that the paper tube is fixed in the axial direction and providing a reference for subsequent conveying. Then, motor 231 drives the lead screw slide 232 to make the hook 233 move out of the slot, avoiding interference when the sliding table moves later.

[0059] The through-type lead screw motor 42 runs and drives the sliding table 44 forward through the multi-segment copper sleeve slide rail 43 of the synchronous chain structure, pushing the paper tube on the paper management platform to the top of the active roller 53 of the slitting and rewinding machine 5.

[0060] After the paper management platform 3 extends to its final position, the double half-shaft telescopic platform 55 rises above the paper management platform 3 and stops at the upper limit proximity switch. The cylinder 7 541 completes its stroke, causing the four rotating rods 542 to form a support. The double half-shaft telescopic platform 55 then descends to the support and stops after being detected by the lower limit proximity switch. The geared motor 552, through the chain drive mechanism 3 554 and the multi-segment copper sleeve slide rail 2 557, causes the two half-shafts 56 to synchronously extend and retract towards the center, inserting into the inner diameter of the paper tube. After the half-shafts 56 are fully inserted, the solenoid valve controls compressed air to inflate through the high-speed rotary joint 556, causing the half-shafts 56 to expand and fix the paper tube. The two half-shafts 56... After the 6-axis is closed, the photoelectric sensor lights up, the controller receives a signal, and the double half-axis telescopic platform 55 receives a signal. Driven by the half-axis lifting mechanism 52, the entire platform moves to the upper limit proximity switch and stops. The controller receives a signal and controls the paper tube retracting platform 3 to the retracting origin. After receiving the signal, the double half-axis telescopic platform 55 moves down with the paper tube between the two active rollers 53 and begins to wind the paper. The active rollers 53 are driven by the drive motor to rotate, and the paper tube is driven to rotate and wind the paper through friction. As the diameter of the paper roll increases, the cylinder 6 521 adjusts the height of the double half-axis telescopic platform 55 in real time to ensure that the paper roll is always in close contact with the active rollers 53.

[0061] When the paper roll reaches the set diameter, the half-shaft air circuit system automatically releases air, the reduction motor 552 reverses to make the half-shaft 56 exit the paper tube, and then the double half-shaft telescopic platform 55 rises to the initial position, waiting for the next feeding.
