[0002] In the production process of a printing and packaging plant, roll materials (such as roll plastic film and roll paper) need to undergo multiple processes, including printing, lamination, curing, and slitting.

[0034] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 As shown, this utility model embodiment provides a material roll threading and pulling device, which includes a frame 1, a lifting mechanism 2 and a clamping and traversing mechanism 3. The lifting mechanism 2 and the clamping and traversing mechanism 3 are both arranged on the frame 1, wherein the material roll is located on the outside of the frame 1 and is opposite to the end of the clamping and traversing mechanism 3.

[0036] like Figure 2 As shown, the lifting mechanism 2 includes a drive component 21 and a support frame 22. The support frame 22 supports the material shaft. The fixed end of the drive component 21 is connected to the frame 1. The drive component 21 is a double-stroke cylinder. Figure 7 and Figure 8 As shown, the telescopic end of the drive member 21 drives the support frame 22 to move vertically between the first position, the second position and the third position. The first position, the second position and the third position are arranged from bottom to top in the vertical direction. The lifting mechanism 2 can drive the support frame 22 to move vertically for feeding the material roll when it is threaded onto the shaft, that is, to send the material shaft from the first position to the third position. At the same time, it is used for taking the material roll away from the shaft, that is, to lower the material shaft from the third position to the second position for subsequent storage of the material shaft.

[0037] The clamping and traversing mechanism 3 includes a linear motion component 31 and a gripper assembly 32. The gripper assembly 32 is used to clamp the material shaft. The linear motion component 31 is disposed on the frame 1 and located above the support frame 22. The linear motion component 31 extends along the width direction of the frame 1. The moving end of the linear motion component 31 drives the gripper assembly 32 to move horizontally and linearly along the width direction of the frame 1 to pull out the material shaft in the material roll disposed at the end of the linear motion component 31 and place it on the support frame 22, or to insert the material shaft on the support frame 22 into the material roll. One end of the linear motion component 31 extends out of the frame 1 so that the gripper assembly 32 can drive the material shaft on it to fully enter the material roll.

[0038] The clamping and lateral movement mechanism 3 can drive the gripper assembly 32 to move horizontally via the linear movement component 31 to complete the shaft threading or pulling action, effectively replacing manual operation, significantly reducing the labor intensity of workers, significantly improving the efficiency of shaft threading and pulling operations, and reducing labor costs, which is conducive to improving production efficiency. In this embodiment, the shaft threading and pulling device achieves mechanized operation of shaft threading and pulling through the coordinated cooperation of the frame 1, the lifting mechanism 2, and the clamping and lateral movement mechanism 3.

[0039] like Figure 3 As shown, the support frame 22 includes a connecting rod 221 and two lifting plates 222. The connecting rod 221 is horizontally oriented and extends along the width of the frame 1. The bottom of the connecting rod 221 is connected to the telescopic end of the drive component 21. The two lifting plates 222 are respectively disposed on both sides of the connecting rod 221. The top of the lifting plate 222 is recessed with an arc-shaped groove, the shape of which is adapted to the outer surface of the material shaft. The arc-shaped groove can provide stable support and positioning for the material shaft, preventing the material shaft from shaking or shifting during the support process, and ensuring the accuracy of the material shaft's position when clamped by the clamping assembly. To further prevent the material shaft from falling off when the support frame 22 receives the material shaft in the first position, a baffle plate 25 is provided on one side of the frame 1. The baffle plate 25 is positioned opposite to the support frame 22 when it is in the first position.

[0040] like Figure 3 As shown, the lifting mechanism 2 also includes a proximity switch 24 mounted on the frame 1. The proximity switch 24 is positioned opposite to the support frame 22 when it is in the first position. It is used to detect whether the material shaft has entered the support frame 22, facilitating automated linkage control of the shaft insertion and removal operation. This improves the intelligence level of the device, reduces the need for manual monitoring, and further enhances the automation level of production. It should be noted that the automated control logic and related programs involved in this embodiment are not within the scope of protection of this patent.

[0041] When the material roll is threaded onto the shaft, the drive unit 21 drives the support frame 22 to the first position, and the material roll enters the arc-shaped groove of the lifting plate 222 of the support frame 22. The proximity switch 24 is used to detect whether the material roll has entered the lifting plate 222 on the support frame 22. The drive unit 22 drives the support frame 22 to move vertically to the third position, which is the shaft threading preparation position, so that the gripper assembly 32 can grip the material roll.

[0042] When the material roll is pulled out by the shaft, the drive unit 21 drives the support frame 22 to the third position to prepare to receive the material roll pulled out by the gripper assembly 32. After the support frame 22 receives the material roll, the drive unit 21 drives the material roll down to the second position to facilitate the subsequent storage of the material roll.

[0043] like Figure 3 As shown, the lifting mechanism 2 also includes two sets of spaced-apart guide components 23. Each set of guide components 23 includes a guide rail 231 and a guide slider 232. The guide rail 231 is vertically oriented on the frame 1, and the guide slider 232 is mounted on the connecting rod 221 and slidably connected to the guide rail 231. When the driving component 21 drives the support frame 22 to move vertically, the guide slider 232 slides along the guide rail 231. When the driving component 21 drives the support frame 22 to move vertically, the guide components 23 can guide the movement direction of the support frame 22, effectively limiting the offset of the support frame 22, making the lifting movement of the support frame 22 more stable and smooth, and improving the stability of the lifting mechanism 2.

[0044] In this embodiment, the guide assembly 23 further includes a limiting plate 233, which is disposed at the top of the guide rail 231 to limit the guide slider 232. That is, the limiting plate 233 can limit the movement stroke of the guide slider 232 to prevent the guide slider 232 from disengaging from the guide rail 231 due to excessive movement. At the same time, when the limiting plate 233 limits the guide slider 232, the drive member 21 drives the support frame 22 to the third position, ensuring that when the support frame 22 is in the third position, the material shaft is exactly at the center position of the gripper assembly 32.

[0045] like Figure 4 and Figure 5As shown, the gripper assembly 32 includes an opening / closing drive unit 321 and two opposing gripper units 322. The opening / closing drive unit 321 is a guide rail slider structure. The guide rail of the opening / closing drive unit 321 extends along the length direction of the frame 1, that is, perpendicular to the extension direction of the linear motion component 31. The moving end of the linear motion component 31 is connected to the guide rail in the opening / closing drive unit 321. The two moving ends on the opening / closing drive unit 321 are respectively connected to the two gripper units 322 and drive the two gripper units 322 to move towards or away from each other to grip or release the material shaft. In this embodiment, the gripper assembly 32 uses a guide rail slider structure to drive the two gripper units 322 to move towards or away from each other, which can achieve stable gripping and releasing of the material shaft. The opening and closing action of the gripper units 322 is highly controllable and can adapt to the gripping requirements of material shafts with different diameter specifications, improving the adaptability of the device to different material shafts.

[0046] like Figure 4 As shown, the two gripper units 322 have identical structures and are mirror-oriented. Each gripper unit 322 includes a connecting plate 3221 and two gripper bodies 3222. The two connecting plates 3221 are respectively connected to the two sliders of the opening and closing drive unit 321. The two gripper bodies 3222 are connected to the bottom end of the connecting plate 3221 and are spaced apart. The two gripper bodies 3222 in the two gripper units 322 are arranged in a one-to-one correspondence. By setting up double gripper bodies 3222, the contact area with the material shaft is increased, making the gripper hold the material shaft more stable, dispersing the clamping force, reducing the risk of damage to the material shaft due to excessive local force, and further improving the reliability of the clamping operation. Of course, to further increase the friction and prevent the material shaft from falling, anti-slip pads are provided on the contact surface of the gripper bodies 3222.

[0047] like Figure 5 As shown, the gripper assembly 32 also includes a synchronization unit 323. The synchronization unit 323 includes a gear 3231 and two racks 3232. The two racks 3232 are respectively connected to the connecting plates 3221 of the two gripper units 322. Both racks 3232 mesh with the gear 3231. The gear 3231 is connected to the opening and closing drive unit 321 through the connecting shaft 3233 and rotates along the axis of the connecting shaft 3233. When the opening and closing drive unit 321 drives the gripper unit 322 to move, the synchronization unit 323 can ensure that the movement of the two gripper units 322 remains synchronized, avoiding material shaft clamping deviation or uneven force due to asynchronous movement of the gripper units 322. This ensures the coordination and consistency of the opening and closing action of the gripper assembly 32 and improves the clamping accuracy.

[0048] like Figure 2As shown, in practical applications, the gripper assembly 32 holds one side of the material shaft. Since the material shaft is relatively long, to prevent it from tilting and failing to accurately enter the material roll when the gripper assembly moves it, the material shaft threading and pulling device also includes a guide wheel mechanism 4. The guide wheel mechanism 4 is mounted on the frame 1 and located below the linear motion assembly 31, near the material roll. The guide wheel mechanism 4 provides rolling support to the material shaft when the gripper assembly 32 holds and moves it. During the movement of the material shaft while gripped by the gripper assembly 32, the guide wheel mechanism 4 provides rolling support, sharing the weight of the material shaft, reducing the stress on the gripper assembly 32, and preventing the material shaft from sagging due to gravity during movement, thus affecting the threading and pulling accuracy and making the material shaft movement more stable.

[0049] like Figure 6 As shown, the guide wheel mechanism 4 includes a telescopic member 41, a connecting frame 42, and a V-shaped roller 43. The V-shaped roller 43 is horizontally oriented and rotatably connected to the connecting frame 42. The telescopic end of the telescopic member 41 is connected to the V-shaped roller 43 through the connecting frame 42 to drive the V-shaped roller 43 to rise and fall. The V-shaped roller 43 is used to support the material shaft. The V-shaped roller can better adapt to the shape of the material shaft and enhance the support stability of the material shaft. During the threading process, after the gripper assembly 32 clamps the material shaft, the telescopic component 41 drives the V-shaped roller 43 to rise to the material support position. When the gripper assembly needs to move in front of the V-shaped roller 43 during the threading process, the front end of the material shaft has already been inserted into the core of the material roll. To avoid interference between the gripper assembly 32 and the V-shaped roller 43, the telescopic component 41 drives the V-shaped roller 43 to descend, and the gripper assembly 32 continues to move to complete the threading process. During the unloading process, after the gripper assembly 32 clamps the material shaft and moves it behind the V-shaped roller 43, the telescopic component 41 drives the V-shaped roller 43 to rise to support the material shaft, and the gripper assembly 32 continues to move to complete the unloading process.

[0050] The material roll is a roll of plastic film or roll of paper, and the material shaft is a rotating structure. The material shaft includes a middle section and overlapping sections on both sides of the middle section. The V-shaped roller 43 supports the middle section of the material shaft, and the gripper assembly 32 clamps the overlapping section on one side of the material shaft.
