[0002] Base paper is a type of paper that requires further processing and is typically used to manufacture various processed papers. The properties, quality, and specifications of base paper vary depending on the processing requirements. For example, composite paper used in printing can be called base paper for printing processing, while white cardboard used to manufacture white cardboard can be called base paper for that composite paper.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0035] like Figure 1 As shown, a paper unwinding and feeding mechanism includes an unwinding base 1, specifically two unwinding bases 1. A support shaft 2 is provided between the bases of the two unwinding bases 1. Two sets of clamping components for clamping the paper are provided on the support shaft 2. Each set of clamping components is provided with an adjusting component for adjusting the distance between the clamping components. The two sets of clamping components are also provided with lifting components for adjusting the height of the clamping components. Each set of lifting components is provided with a sliding component. The two sets of sliding components are installed on the two unwinding bases 1 via a lower crossbeam 3. An upper crossbeam 4 is provided on the top of the two unwinding bases 1. An unwinding roller 5 is provided on the upper crossbeam 4. An unwinding frame 6 is provided on one side of the unwinding base 1. A first platform 7 and a second platform 8 are provided on the unwinding frame 6. An angle adjustment component and a drive component are provided on the first platform 7. A correction component is provided on the second platform 8.

[0036] In use, the lifting component first moves the clamping component to its lowest position. The adjusting component adjusts the distance between the two clamping components according to the width of the paper. The sliding component allows the lifting component and the clamping component to move linearly at the same time, which facilitates the adjustment of the height of the clamping component by the lifting component. After the required width is reached, the clamping component clamps the paper. The lifting component drives the clamping component back to its original position and pulls the paper out through the bottom of the unwinding roller 5. The angle adjusting component bends the paper accordingly, and the driving component continuously pulls out the paper. The correction component adjusts according to the width of the paper.

[0037] By setting two sets of clamping components on the support shaft 2, the raw paper can be clamped from different positions. The clamping components are equipped with adjustment components, which can precisely adjust the distance between the two sets of clamping components according to the width of the raw paper, further enhancing the reliability of clamping. The addition of the sliding component allows the two sets of lifting components and the clamping components as a whole to slide horizontally on the lower crossbeam 3. The upper crossbeam 4 provides a stable support structure for the unwinding roller 5. The correction component can monitor the deviation of the raw paper in real time during the unwinding process and correct the deviation of the raw paper through automatic adjustment or other methods to ensure that the raw paper is always unwound along the predetermined path, further improving the accuracy and stability of unwinding. The angle adjustment component can adjust the angle of the raw paper during the unwinding process according to actual needs to adapt to the requirements of different subsequent processing steps. The drive component provides power for the unwinding process and can precisely control the unwinding speed.

[0038] like Figure 1 and Figure 3 As shown, the clamping assembly includes a clamping plate 9, one end of which is rotatably connected to the support shaft 2, and the other end of which is provided with a chuck 10. It also includes a clamping mounting plate 11, which is bolted to the clamping plate 9 and rotatably connected to the support shaft 2.

[0039] The support shaft 2 provides support for the installation of the clamping assembly. The clamping plate 9 can drive the chuck 10 to rotate, which facilitates the chuck 10 to clamp the paper. The clamping mounting plate 11 allows the clamping plate 9 to be installed on the support shaft 2, preventing the clamping plate 9 from falling off the support shaft 2. At the same time, the clamping mounting plate 11 has a hollow structure, which facilitates the installation of the adjustment assembly and the adjustment of the clamping assembly.

[0040] like Figures 1 to 4 As shown, the adjustment assembly includes an adjustment cylinder 12, which is fixed to the support shaft 2 by bolts through an adjustment mounting plate 13. An adjustment joint is provided on the piston rod of the adjustment cylinder 12, and an adjustment connecting plate 14 is provided on the adjustment joint. The adjustment connecting plate 14 is bolted to the inner wall of the clamping mounting plate 11.

[0041] The adjusting mounting plate 13 provides support for the adjusting cylinder 12, so that the adjusting cylinder 12 is securely mounted on the support shaft 2. The piston rod of the adjusting cylinder 12 extends or retracts, and drives the adjusting connecting plate 14 to move through the adjusting joint. The displacement of the adjusting connecting plate 14 can drive the two sets of clamping components to move, thereby adjusting the distance between the two sets of clamping components to adapt to the paper of different widths.

[0042] like Figure 2 and Figure 3 As shown, the lifting assembly includes a lifting cylinder 15. A lifting joint is provided on the piston rod of the lifting cylinder 15. A lifting connecting seat 16 is rotatably connected to the lifting joint. The lifting connecting seat 16 is located at the bottom of the clamping plate 9. The lifting cylinder 15 is connected to the sliding assembly through a lifting mounting seat 17.

[0043] The lifting cylinder 15 is securely mounted on the sliding assembly via the lifting mounting seat 17. The piston rod of the lifting cylinder 15 extends or retracts, driving the lifting connecting seat 16 to rise or fall via the lifting joint. The rise or fall of the lifting connecting seat 16 can drive the clamping assembly to rise or fall.

[0044] like Figure 2 and Figure 3 As shown, the sliding assembly includes two slide rails 18 located at the top and bottom of the lower crossbeam 3. Each slide rail 18 is slidably connected to a slide table 19. A sliding plate 20 is bolted to each slide table 19. A lifting mounting seat 17 is located on one side of the sliding plate 20.

[0045] During the process of adjusting the spacing between the clamping components, the lifting components will be driven to make corresponding linear displacement. The sliding plate 20 connects the slide table 19 and the lifting cylinder 15, and the slide rail 18 and the slide table 19 enable the lifting components to make smooth displacement.

[0046] like Figure 5 and Figure 6 As shown, the angle adjustment assembly includes an adjustment base 21, specifically two adjustment bases 21, which are set on the first platform 7. An adjustment roller 22 is set between the two adjustment bases 21. A roller frame 23 is rotatably connected to both ends of the adjustment roller 22. Several adjustment shafts 24 are set between the two roller frames 23. The adjustment roller 22 is rotated by an adjustment motor 25, which is set on the adjustment base 21.

[0047] The adjusting motor 25 is a worm gear reducer, and the adjusting base 21 provides support for the whole. The adjusting motor 25 rotates the adjusting roller 22 through its output shaft. The two roller frames 23 are connected to each other through the adjusting shaft 24. The rotation of the adjusting roller 22 can simultaneously drive the two roller frames 23 to rotate accordingly. The roller frames 23 bend the flat base paper at the corresponding angle.

[0048] like Figure 5 and Figure 7 As shown, the drive assembly includes a drive base 26, and there are two drive bases 26. The two drive bases 26 are set on the first platform 7. A drive roller 27 and a driven roller 28 are rotatably connected between the two drive bases 26. A drive motor 29 is rotatably connected to one end of the drive roller 27. The drive motor 29 is set on the drive base 26.

[0049] The paper is clamped between the active roller 27 and the driven roller 28 by the angle adjustment component. The drive motor 29 drives the active roller 27 to rotate, and the paper leaves the surface of the active roller 27 and the driven roller 28 and makes corresponding displacement. The driven roller 28 plays an auxiliary positioning role.

[0050] like Figure 5 and Figure 8 As shown, the correction assembly includes two correction bases 30, which are located on the top of the second platform 8. Two correction rollers 31 are positioned between the two correction bases 30. An adjusting block 32 is slidably connected to both ends of each correction roller 31. Each adjusting block 32 is equipped with a guide plate 33 and a screw shaft 34 threadedly connected to it. The top of the guide plate 33 is slidably connected to one correction roller 31, and the bottom of the guide plate 33 is slidably connected to a transition shaft 35. A clamping block 36 is provided at both ends of the transition shaft 35, and the top of each clamping block 36 is connected to one correction roller 31. The two ends of the screw shaft 34 are rotatably connected to the two correction bases 30 via bearings, and a correction handwheel 37 is provided on one side of the screw shaft 34.

[0051] Rotating the lead screw shaft 34 by the correction handwheel 37 causes the adjusting block 32 to slide on the surface of the correction roller 31. The sliding of the adjusting block 32 drives the guide plate 33 to slide accordingly. The guide plate 33 guides the raw paper. The guide plates 33 on both sides are adjusted according to the width of the raw paper. Through the connection between the clamping block 36 and the correction roller 31, the transition shaft 35 is supported and will not wobble or deviate. At the same time, the transition shaft 35 passes through the two guide plates 33, providing support for the guide plates 33, so that the raw paper can remain stable as it passes through the guide plates 33.

[0052] like Figure 2 As shown, each sliding plate 20 has a limiting base 38 on its top. Each limiting base 38 is rotatably connected to a limiting arm 39. Each limiting arm 39 is rotatably connected to a limiting top seat 40. Each limiting top seat 40 is bolted to a clamping plate 9. The limiting base 38 provides corresponding support for the limiting arm 39. The clamping assembly can be limited by the limiting base 38, the limiting arm 39 and the limiting top seat 40.

[0053] Working principle: In use, the lifting cylinder 15 lowers the clamping plate 9 to its lowest position via the lifting connecting seat 16. The adjusting cylinder 12 slides the clamping mounting plate 11 on the support shaft 2 via the adjusting connecting plate 14. While the adjusting cylinder 12 slides the clamping mounting plate 11, the lifting cylinder 15 and the clamping plate 9 move linearly simultaneously via the slide rail 18, slide table 19, and sliding plate 20. The sliding of the clamping mounting plate 11 drives the sliding of the clamping plate 9. After reaching the width of the raw paper, the chuck 10 clamps the raw paper accordingly. The lifting cylinder 15 drives the clamping plate 9 back to its original position. The raw paper is lifted by the clamping assembly and pulled out, passing through the bottom of the unwinding roller 5 and the angle adjusting assembly. The adjusting motor 25 rotates the adjusting roller 22 through its output shaft. The rotation of the adjusting roller 22 can simultaneously drive the two roller frames 23 to rotate accordingly. The roller frames 23 bend the originally flat paper at a corresponding angle. The paper leaves the top of the roller frames 23 and enters between the driving roller 27 and the driven roller 28. The drive motor 29 drives the driving roller 27 to rotate. The paper leaves the surface of the driving roller 27 and the driven roller 28 and makes a corresponding displacement. The correction handwheel 37 rotates the lead screw shaft 34. The rotation of the lead screw shaft 34 causes the adjusting block 32 to slide on the surface of the correction roller 31. The sliding of the adjusting block 32 can drive the guide plate 33 to slide accordingly. The guide plate 33 guides and limits the paper to achieve correction. The guide plates 33 on both sides are adjusted according to the width of the paper.

[0054] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
