Description

Technical Field

[0001] This invention relates to the field of thin film production and processing technology, and in particular to a multi-station three-dimensional shaft pulling device and its usage method for a high-speed thin film production line. Background Technology

[0002] In the winding process of film production, the air shaft is the core component that carries the paper core and completes the film winding. On the production line, after the film is wound up, the air shaft needs to be pulled out of the paper core, and the empty air shaft is placed back into the waiting position of the winding equipment to prepare for the next round of winding.

[0003] In existing technologies, traditional air shaft pulling equipment is mostly a single-station structure. Its operation process is generally as follows: after winding, the air shaft with film and paper core is removed from the winding station by manual or semi-automatic equipment and sent to the air shaft pulling station for pulling. After the air shaft is pulled, the empty air shaft is transported to the production line to wait for the shaft to be put back on. The whole process is a serial operation. The operation cycle of a single air shaft from pulling to re-putting it on the shaft is as long as 20 minutes, which mainly depends on the skill level of the operator.

[0004] However, with the continuous upgrading of film production technology, the winding speed of winding equipment has also been greatly improved. The operating efficiency of traditional single-station shaft pulling equipment has become a bottleneck of the production line. That is, the upper shaft speed cannot match the winding cycle, resulting in excessively long waiting time for the winding equipment, which seriously restricts the overall capacity of the production line. At the same time, the manual handling process also has problems such as high labor intensity, insufficient operational safety, and poor shaft positioning accuracy, which cannot meet the needs of high-speed and automated film production. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-station three-dimensional shaft pulling device for high-speed film production lines. This device is suitable for film processing scenarios such as extrusion composite production lines and can realize automated continuous operation of rapid extraction, conveying and mounting of air shafts from paper cores, meeting the capacity requirements of high-speed winding production lines, while improving the level of automation and safety of operations.

[0006] Another object of the present invention is to provide a method of using the above-described multi-station three-dimensional shaft-pulling device for a high-speed thin film production line.

[0007] The technical solution of the present invention is as follows: a multi-station three-dimensional shaft pulling device for a high-speed thin film production line, comprising a shaft pulling mechanism, a transverse moving mechanism, and an upper shaft mechanism connected sequentially along the conveying direction of the air expansion shaft. The shaft pulling mechanism is provided with a shaft pulling station, and the upper shaft mechanism is provided with an upper shaft station. The shaft pulling mechanism and the upper shaft mechanism are respectively located on opposite sides of the transverse moving mechanism. The transverse moving mechanism includes a transverse moving fixed frame, a first transverse moving movable frame, and a second transverse moving movable frame. The first transverse moving movable frame moves horizontally relative to the transverse moving fixed frame, and the horizontal movement limit positions of the first transverse moving movable frame are the shaft pulling station and the upper shaft station, respectively. The second transverse moving movable frame moves horizontally relative to the first transverse moving movable frame, and the horizontal movement limit positions of the second transverse moving movable frame are the opposite sides of the first transverse moving movable frame, respectively. The horizontal movement direction of the first transverse moving movable frame is the same as the horizontal movement direction of the second transverse moving movable frame. In this device structure, the traditional single-station serial "shaft pulling-transferring-shaft mounting" process is broken down into three independent stations: shaft pulling, conveying, and shaft mounting. Each station works in coordination and can handle different air shafts in parallel, completely breaking the efficiency bottleneck of serial operation. This significantly shortens the traditional single-shaft operation cycle from 20 minutes, thus matching the high-speed winding rhythm. Furthermore, it can achieve fully automated connection of the entire process. Through the relative horizontal movement between the transverse fixed frame and the first transverse movable frame, and the relative horizontal movement between the first transverse fixed frame and the second transverse movable frame, the dual-drive conveying structure enables automated transfer between shaft pulling and shaft mounting without manual intervention. This eliminates the safety hazards and positioning errors of manual handling and improves operational stability.

[0008] In the lateral movement mechanism, a first rack is provided at the bottom of the first lateral movement frame. The first rack is arranged along the horizontal movement direction of the first lateral movement frame. A first drive motor is provided on the lateral movement fixed frame. The power output end of the first drive motor is connected to a first gear, and the first gear meshes with the first rack. The power output end of the first drive motor is connected to the first gear through a reducer. The first drive motor drives the first gear to rotate, and the rotation of the first gear drives the first rack to move horizontally, thereby driving the entire first lateral movement frame and the second lateral movement frame above it to move horizontally.

[0009] The bottom of the second transverse movable frame is equipped with a first lead screw nut, and the first transverse movable seat is equipped with a first lead screw. The first lead screw nut cooperates with the first lead screw, and one end of the first lead screw is connected to a second drive motor. The first lead screw nut is fixedly installed on the bottom of the second transverse movable frame via a nut seat. The power output end of the second drive motor is connected to one end of the first lead screw via a reducer. Both ends of the first lead screw are respectively installed on the first transverse movable frame via bearing assemblies. When the second drive motor drives the first lead screw to rotate, the first lead screw nut drives the entire second transverse movable frame to move horizontally relative to the first transverse movable frame, thereby moving the air shaft placed on the second transverse movable frame, switching between the shaft pulling station and the shaft mounting station.

[0010] Furthermore, in the lateral movement mechanism, the bottom of the first lateral moving frame is also provided with a first slider, and the two sides of the lateral moving fixed frame are respectively provided with first slide rails. The first slider cooperates with the first slide rails, and the two first slide rails are respectively parallel to each other on both sides of the first rack. The bottom of the second lateral moving frame is also provided with a second slider, and the two sides of the first lateral moving frame are respectively provided with second slide rails. The second slider cooperates with the second slide rails, and the two second slide rails are respectively parallel to each other on both sides of the first lead screw. The cooperation between the first slide rail and the first slider not only guides the horizontal movement of the first lateral moving frame, but also makes the overall structure and horizontal movement of the entire first lateral moving frame more stable and precise. The cooperation between the second slide rail and the second slider not only guides the horizontal movement of the second lateral moving frame, but also makes the overall structure and horizontal movement of the entire second lateral moving frame more stable and precise.

[0011] In the lateral movement mechanism, the lateral movement fixing frame includes a fixing frame and a first support leg. Multiple first support legs are distributed at the bottom of the fixing frame. A first crossbar is provided in the middle of the fixing frame. A first drive motor is fixedly installed on the first crossbar. Two first slide rails are located on both sides of the first crossbar.

[0012] The first transverse movable frame has a frame structure. A second crossbar is provided in the middle of the first transverse movable frame. A first rack is installed at the bottom of the second crossbar. First lead screws are provided on both sides of the second crossbar. A second slide rail is provided on the side of the first transverse movable frame outside each first lead screw.

[0013] The second transverse movable frame has a longitudinal rod-like structure, including a first longitudinal support rod and end support members. A first screw nut is provided at the bottom of the first longitudinal support rod, and end support members extend upward from both ends of the first longitudinal support rod. Each end support member has a first groove.

[0014] The shaft pulling mechanism and the upper shaft mechanism have the same structure but run in opposite directions. They each include a lifting base, a longitudinal moving assembly, a clamping head assembly, and a lifting assembly. The lifting base is mounted on the longitudinal moving assembly, and the clamping head assembly and the lifting assembly are mounted on the lifting base. The lifting base serves as the mounting base for the clamping head assembly and the lifting assembly. It can move horizontally relative to the longitudinal moving assembly along the axis of the air shaft, and the clamping head assembly on it can also clamp the air shaft and drive it to move up and down.

[0015] The longitudinal moving assembly includes a longitudinal moving frame, second legs, a second longitudinal support rod, and a second rack. Multiple second legs are distributed at the bottom of the longitudinal moving frame, and a second longitudinal support rod is located in the middle of the longitudinal moving frame. A second rack is mounted on the second longitudinal support rod. The bottom of the lifting base has a motor mounting base, a third drive motor, and a second gear. The third drive motor is fixedly mounted to the bottom of the lifting base via the motor mounting base. The power output end of the third drive motor is connected to the second gear, which meshes with the second rack. The power output end of the third drive motor is connected to the second gear via a reducer. The second drive motor drives the second gear, and the engagement of the second gear and the second rack allows the entire lifting base, along with its clamping assembly and lifting assembly, to move relative to the longitudinal moving assembly. The clamping assembly holds the air shaft, enabling shaft pulling or mounting actions. In addition, to make the translational movement of the lifting base more stable and precise, third slide rails can be set on both sides of the second longitudinal support rod on the longitudinal moving frame. Correspondingly, a matching third slider is installed at the bottom of the lifting base. The cooperation between the third slider and the third slide rail plays a guiding and stabilizing role for the translational movement of the lifting base.

[0016] The lifting assembly includes an upper slide, a fourth drive motor, a second lead screw, a second lead screw nut, and a nut seat. A nut seat is fixedly installed on one side of the upper slide, and the second lead screw nut is housed within the nut seat. The second lead screw nut and the second lead screw cooperate with each other. The second lead screw is vertically positioned within the lifting base, and one end of the second lead screw is connected to the power output end of the fourth drive motor. The power output end of the fourth drive motor is connected to the second lead screw via a helical gear-worm gear reducer. The upper and lower ends of the second lead screw are respectively mounted on the lifting base via bearing assemblies. When the fourth drive motor drives the second lead screw to rotate, the second lead screw drives the second lead screw nut and nut seat to move up and down, thereby driving the upper slide and the chuck assembly to move up and down, realizing the placement or lifting of the air shaft on the second transverse movable frame. Furthermore, to make the lifting movement of the upper slide more stable and precise, fourth slide rails can be installed on both sides of the lifting base. Correspondingly, a cooperating fourth slider is installed at a corresponding location on the upper slide. The cooperation between the fourth slider and the fourth slide rail provides guidance and stability for the lifting movement of the upper slide.

[0017] The clamping assembly is mounted on the upper slide and includes a front fixed plate, a cylinder, a retaining ring, a rotating shaft, a clamping block, and a clamping seat. The front fixed plate is the front side plate of the upper slide facing the air shaft. A second groove is provided at the lower part of the front fixed plate, and a rotating shaft is provided above the second groove. The retaining ring is connected to the rotating shaft, and the top of the retaining ring is connected to the cylinder, which is located on the upper slide. On the upper slide, the side opposite to the front side plate is the rear side plate, and the clamping block is mounted on the rear side plate through the clamping seat. The cylinder can drive the clamping ring to rotate around the rotating shaft, causing the retaining ring to deflect relative to the second groove on the front fixed plate, thereby achieving the clamping or releasing action of the air shaft. The clamping block can adopt a traditional claw structure, using the opening and closing action of the clamping block to clamp or release the air shaft.

[0018] On the upper slide block, probes are respectively installed near the retaining ring and the retaining block. During the process of pulling or lifting the shaft, the position of the air shaft is monitored in real time by the probes to achieve precise clamping or loosening of the retaining ring and the retaining block.

[0019] The method of using the multi-station three-dimensional shaft pulling device in the aforementioned high-speed film production line is as follows: The multi-station three-dimensional shaft pulling device is placed near the winding mechanism of the high-speed film production line. After the film winding is completed, the air shaft with the paper core is sent to the shaft pulling station, where it is pulled out by the shaft pulling mechanism. The first and second transverse movable frames in the transverse mechanism move horizontally towards the shaft pulling station to their limit positions, where they receive the air shaft. Subsequently, the first and second transverse movable frames move horizontally towards the upper shaft station to their limit positions, sending the air shaft to the upper shaft station, where the upper shaft mechanism clamps the air shaft, ready for the next round of winding. The specific process of "shaft pulling-conveying-uploading" is as follows:

[0020] (1) At the shaft pulling station, when the shaft pulling mechanism pulls the shaft, the lifting base first moves along the longitudinal moving component to a position close to the winding mechanism. After the end of the air shaft is precisely clamped by the chuck component, the lifting base drives the air shaft to gradually move backward, and smoothly pulls the air shaft out of the paper core. After the shaft pulling is completed, the lifting component drives the upper slide, chuck component and air shaft to rise to the preset shaft picking height, waiting for delivery.

[0021] (2) In the transverse mechanism, under the drive of the first drive motor and the second drive motor, the first transverse movable frame and the second transverse movable frame move horizontally toward the shaft pulling station, until the second transverse movable frame reaches the shaft pulling station. At this time, the second transverse movable frame is located below the air shaft. After the upper slide and the chuck assembly on the shaft pulling mechanism drive the air shaft to descend to the position, the chuck assembly releases the air shaft, so that the air shaft is placed on the positioning fixture (i.e. the above-mentioned end support) on the second transverse movable frame. Subsequently, under the drive of the first drive motor and the second drive motor, the first transverse movable frame and the second transverse movable frame move horizontally toward the upper shaft station, until the second transverse movable frame reaches the upper shaft station.

[0022] (3) At the upper shaft station, the upper slide and chuck assembly in the upper shaft mechanism first descend, accurately clamp the end of the air shaft, and then rise. At this time, the first and second transverse movable frames in the transverse mechanism are reset and waiting for the next conveying. When the upper shaft is in operation, the lifting base of the upper shaft mechanism drives the air shaft to gradually move to the vicinity of the winding mechanism, and gradually inserts the air shaft into the paper core inside the winding mechanism during the movement, thereby completing the upper shaft action.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] This multi-station three-dimensional shaft extraction device and its application method for high-speed film production lines are applicable to film processing scenarios such as extrusion lamination production lines. It enables automated continuous operation of rapid extraction, conveying, and mounting of air-expanding shafts from paper cores, meeting the capacity requirements of high-speed winding production lines while improving automation and safety. Specifically, through a parallel operation design, the traditional single-station serial "shaft extraction-transfer-mounting" process is broken down into three independent stations: shaft extraction, conveying, and mounting. Each station works collaboratively, handling different air-expanding shafts in parallel, completely breaking the efficiency bottleneck of serial operations and significantly shortening the traditional single-shaft operation cycle from 20 minutes to match the high-speed winding pace. Furthermore, it achieves fully automated process integration. Through the relative horizontal movement between the lateral fixed frame and the first lateral movable frame, and the relative horizontal movement between the first lateral fixed frame and the second lateral movable frame, the dual-drive conveying structure enables automated transfer between shaft extraction and mounting without manual intervention, eliminating the safety hazards and positioning errors of manual handling and improving operational stability.

[0025] In the multi-station three-dimensional shaft pulling device used in high-speed film production lines, the transverse mechanism can flexibly enter and exit the shaft pulling station and the upper shaft station by setting two levels of horizontal transverse units. Its structure is simple, flexible and convenient to use. Its shaft pulling mechanism and upper shaft mechanism have the same structure but opposite operation process. By setting longitudinal translation, lifting, clamping and other actions, the structure and principle are relatively simple, the equipment cost is also low, which is conducive to large-scale promotion and application in film production lines.

Detailed Implementation

[0038] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0039] Example 1

[0040] This embodiment provides a multi-station three-dimensional shaft-extraction device for a high-speed thin-film production line, such as... Figure 1As shown, the mechanism includes a shaft-pulling mechanism a, a transverse movement mechanism b, and an upper shaft mechanism c, which are connected sequentially along the conveying direction of the air expansion shaft d. The shaft-pulling mechanism has a shaft-pulling station, and the upper shaft mechanism has an upper shaft station. The shaft-pulling mechanism and the upper shaft mechanism are respectively located on opposite sides of the transverse movement mechanism. The transverse movement mechanism includes a transverse movement fixed frame 1, a first transverse movement movable frame 2, and a second transverse movement movable frame 3. The first transverse movement movable frame moves horizontally relative to the transverse movement fixed frame, and its horizontal movement limit positions are the shaft-pulling station and the upper shaft station, respectively. The second transverse movement movable frame moves horizontally relative to the first transverse movement movable frame, and its horizontal movement limit positions are the opposite sides of the first transverse movement movable frame, respectively. The horizontal movement direction of the first transverse movement movable frame is the same as that of the second transverse movement movable frame. In this device structure, the traditional single-station serial "shaft pulling-transferring-shaft mounting" process is broken down into three independent stations: shaft pulling, conveying, and shaft mounting. Each station works in coordination and can handle different air shafts in parallel, completely breaking the efficiency bottleneck of serial operation. This significantly shortens the traditional single-shaft operation cycle from 20 minutes, thus matching the high-speed winding rhythm. Furthermore, it can achieve fully automated connection of the entire process. Through the relative horizontal movement between the transverse fixed frame and the first transverse movable frame, and the relative horizontal movement between the first transverse fixed frame and the second transverse movable frame, the dual-drive conveying structure enables automated transfer between shaft pulling and shaft mounting without manual intervention. This eliminates the safety hazards and positioning errors of manual handling and improves operational stability.

[0041] like Figure 4As shown, in the transverse mechanism, a first rack 4 is provided at the bottom of the first transverse movable frame. The first rack is arranged along the horizontal movement direction of the first transverse movable frame. A first drive motor 5 is provided on the transverse fixed frame. The power output end of the first drive motor is connected to a first gear 6, which meshes with the first rack. The power output end of the first drive motor is connected to the first gear through a reducer. The first drive motor drives the first gear to rotate, and the rotation of the first gear drives the first rack to move horizontally, thereby driving the entire first transverse movable frame and the second transverse movable frame above it to move horizontally. A first lead screw nut 7 is provided at the bottom of the second transverse movable frame. A first lead screw 8 is provided on the first transverse movable seat. The first lead screw nut cooperates with the first lead screw, and one end of the first lead screw is connected to a second drive motor (not shown in the figure). The first lead screw nut is fixedly installed at the bottom of the second transverse movable frame via a nut seat. The power output end of the second drive motor is connected to one end of the first lead screw via a reducer. Both ends of the first lead screw are respectively installed on the first transverse movable frame via bearing assemblies. When the second drive motor drives the first lead screw to rotate, the first lead screw nut drives the entire second transverse movable frame to move horizontally relative to the first transverse movable frame, thereby driving the air shaft placed on the second transverse movable frame to move, switching between the shaft pulling position and the shaft mounting position. Furthermore, the bottom of the first transverse movable frame is also provided with a first slider 9, and the two sides of the transverse fixed frame are respectively provided with first slide rails 10. The first slider cooperates with the first slide rails, and the two first slide rails are respectively parallel to each other on both sides of the first rack. The bottom of the second transverse movable frame is also provided with a second slider 11, and the two sides of the first transverse movable frame are respectively provided with second slide rails 12. The second slider cooperates with the second slide rails, and the two second slide rails are respectively parallel to each other on both sides of the first lead screw. The cooperation between the first slide rail and the first slider not only guides the horizontal movement of the first transverse movable frame, but also makes the overall structure and horizontal movement of the first transverse movable frame more stable and precise. Similarly, the cooperation between the second slide rail and the second slider not only guides the horizontal movement of the second transverse movable frame, but also makes the overall structure and horizontal movement of the second transverse movable frame more stable and precise.

[0042] In the transverse movement mechanism, the transverse movement fixed frame includes a fixed frame 13 and first support legs 14. Multiple first support legs are distributed at the bottom of the fixed frame. A first crossbar 15 is located in the middle of the fixed frame. A first drive motor is fixedly mounted on the first crossbar. Two first slide rails are located on both sides of the first crossbar. The first transverse movement movable frame has a frame structure. A second crossbar 16 is located in the middle of the first transverse movement movable frame. A first rack is installed at the bottom of the second crossbar. First lead screws are located on both sides of the second crossbar. Second slide rails are located on the outer sides of the first transverse movement movable frame of each first lead screw. The second transverse movement movable frame has a longitudinal rod structure, including a first longitudinal support rod 17 and end support members 18. A first lead screw nut is located at the bottom of the first longitudinal support rod. End support members extend upward from both ends of the first longitudinal support rod, and each end support member has a first groove.

[0043] like Figures 5 to 9 As shown, the shaft pulling mechanism and the upper shaft mechanism have the same structure but run in opposite directions. They each include a lifting base 19, a longitudinal moving assembly, a clamping head assembly, and a lifting assembly. The lifting base is mounted on the longitudinal moving assembly, and the clamping head assembly and the lifting assembly are mounted on the lifting base. The lifting base serves as the mounting base for the clamping head assembly and the lifting assembly. It can move horizontally relative to the longitudinal moving assembly along the axis of the air shaft, and the clamping head assembly on it can also clamp the air shaft and drive it to move up and down.

[0044] The longitudinal moving assembly includes a longitudinal moving frame 20, a second support leg 21, a second longitudinal support rod 22, and a second rack 23. Multiple second support legs are distributed at the bottom of the longitudinal moving frame, and a second longitudinal support rod is located in the middle of the longitudinal moving frame. A second rack is mounted on the second longitudinal support rod. The bottom of the lifting base is equipped with a motor mounting base 24, a third drive motor 25, and a second gear 26 (e.g., ...). Figure 8 As shown, the third drive motor is fixedly mounted on the bottom of the lifting base via a motor mounting bracket. The power output end of the third drive motor is connected to the second gear, which meshes with the second rack. The power output end of the third drive motor is connected to the second gear via a reducer. The second drive motor drives the second gear, and the engagement of the second gear and the second rack allows the entire lifting base, including the chuck assembly and lifting assembly, to move relative to the longitudinal moving assembly. The chuck assembly clamps the air shaft, enabling shaft pulling or mounting actions. Furthermore, to make the translational movement of the lifting base more stable and precise, third slide rails 40 can be installed on both sides of the second longitudinal support rod on the longitudinal moving frame. Correspondingly, a matching third slider 41 is installed at the bottom of the lifting base. The engagement between the third slider and the third slide rail provides guidance and stability for the translational movement of the lifting base.

[0045] The lifting assembly includes an upper slide 27, a fourth drive motor 28, a second lead screw 29, a second lead screw nut 30, and a nut seat 31. A nut seat is fixedly installed on one side of the upper slide, and a second lead screw nut is installed inside the nut seat. The second lead screw nut and the second lead screw cooperate with each other. The second lead screw is vertically positioned within the lifting base, and one end of the second lead screw is connected to the power output end of the fourth drive motor. The power output end of the fourth drive motor is connected to the second lead screw via a helical gear-worm gear reducer. The upper and lower ends of the second lead screw are respectively mounted on the lifting base via bearing assemblies 32. When the fourth drive motor drives the second lead screw to rotate, the second lead screw drives the second lead screw nut and nut seat to move up and down, thereby driving the upper slide and the chuck assembly to move up and down, realizing the placement or lifting of the air shaft on the second transverse movable frame. In addition, to make the lifting and lowering movement of the upper slide more stable and precise, a fourth slide rail 42 can be set on both sides of the lifting base. Correspondingly, a matching fourth slider 43 can be set at the corresponding position of the upper slide. The cooperation between the fourth slider and the fourth slide rail plays a guiding and stabilizing role for the lifting and lowering movement of the upper slide.

[0046] The clamping assembly is mounted on the upper slide and includes a front fixing plate 33, a cylinder 34, a retaining ring 35, a rotating shaft 36, a clamping block 37, and a clamping seat 38. The front fixing plate is the front side plate of the upper slide facing the air shaft. A second groove 44 is provided at the lower part of the front fixing plate, and a rotating shaft is provided above the second groove. The retaining ring is connected to the rotating shaft, and the top of the retaining ring is connected to the cylinder, which is located on the upper slide. On the upper slide, the side opposite to the front side plate is the rear side plate, and the clamping block is mounted on the rear side plate through the clamping seat. The cylinder can drive the clamping ring to rotate around the rotating shaft, causing the retaining ring to deflect relative to the second groove on the front fixing plate, thereby achieving the clamping or releasing action of the air shaft. The clamping block can adopt a traditional claw structure, using the opening and closing action of the clamping block to clamp or release the air shaft. On the upper slide block, probes 39 are respectively installed near the retaining ring and the retaining block. During the process of pulling or installing the shaft, the probes monitor the position of the air shaft in real time, so as to achieve precise clamping or loosening of the retaining ring and the retaining block. The state of the clamping head assembly when clamping the air shaft is as follows: Figure 9 As shown.

[0047] Example 2

[0048] This embodiment provides a method for using the multi-station three-dimensional shaft-pulling device of the high-speed thin film production line described in Embodiment 1, such as... Figure 2 or Figure 3As shown, specifically: the multi-station three-dimensional shaft pulling device is located near the winding mechanism of the high-speed film production line. After the film winding is completed, the air shaft with the paper core is sent to the shaft pulling station, where it is pulled out by the shaft pulling mechanism. In the transverse movement mechanism, both the first and second transverse movement frames move horizontally towards the shaft pulling station to their limit positions. The transverse movement mechanism receives the air shaft at the shaft pulling station. Subsequently, both the first and second transverse movement frames move horizontally towards the upper shaft station to their limit positions, sending the air shaft to the upper shaft station, where the upper shaft mechanism clamps the air shaft, ready for the next round of winding. The specific process of "shaft pulling-conveying-uploading" is as follows:

[0049] (3) At the shaft pulling station, when the shaft pulling mechanism pulls the shaft, the lifting base first moves along the longitudinal moving component to a position close to the winding mechanism. After the end of the air shaft is precisely clamped by the chuck component, the lifting base drives the air shaft to gradually move backward, and smoothly pulls the air shaft out of the paper core. After the shaft pulling is completed, the lifting component drives the upper slide, chuck component and air shaft to rise to the preset shaft picking height, waiting for delivery.

[0050] (4) In the transverse mechanism, under the drive of the first drive motor and the second drive motor, the first transverse movable frame and the second transverse movable frame move horizontally toward the shaft pulling station. When the second transverse movable frame reaches the shaft pulling station, the second transverse movable frame is located below the air shaft. After the upper slide and the chuck assembly on the shaft pulling mechanism drive the air shaft to descend to the position, the chuck assembly releases the air shaft, so that the air shaft is placed on the positioning fixture (i.e. the above-mentioned end support) on the second transverse movable frame. Subsequently, under the drive of the first drive motor and the second drive motor, the first transverse movable frame and the second transverse movable frame move horizontally toward the upper shaft station. When the second transverse movable frame reaches the upper shaft station.

[0051] (3) At the upper shaft station, the upper slide and chuck assembly in the upper shaft mechanism first descend, accurately clamp the end of the air shaft, and then rise. At this time, the first and second transverse movable frames in the transverse mechanism are reset and waiting for the next conveying. When the upper shaft is in operation, the lifting base of the upper shaft mechanism drives the air shaft to gradually move to the vicinity of the winding mechanism, and gradually inserts the air shaft into the paper core inside the winding mechanism during the movement, thereby completing the upper shaft action.

[0052] As described above, the present invention can be well implemented. The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention; that is, all equivalent changes and modifications made in accordance with the content of the present invention are covered by the scope of protection claimed in the claims of the present invention.
