Description

Technical Field

[0001] The invention relates to a compact coiled material traction and longitudinal cutting integrated mechanism. Background Art

[0002] Coil processing equipment is a mechanical device used to process various materials into coil form.

[0003] The main components of the slitting machine are a frame, unwinding mechanism, cutting mechanism, rewinding mechanism, transmission system, and control system. The unwinding mechanism supports the coiled material to be slit and provides stable unwinding tension. The cutting mechanism is a key component of the slitting machine. It selects the appropriate cutting tool and drive device according to different cutting methods (such as blade cutting, laser cutting, and hot cutting) to achieve precise cutting. The rewinding mechanism neatly rewinds the slit small rolls. It is suitable for slitting a variety of coiled materials such as paper, plastic film, metal foil, and tape, and is widely used in the packaging, printing, electronics, and building materials industries.

[0004] Existing coil processing equipment typically separates the pulling and slitting functions, typically using a pneumatic toolholder loaded with a circular cutter for coil slitting. This results in bulky and complex equipment, requiring multiple power sources. This design not only increases manufacturing costs and maintenance difficulties, but also reduces production efficiency. Furthermore, existing slitting mechanisms are prone to rough edges, burrs, and uneven slitting widths when slitting harder materials (such as chilled aluminum), impacting product quality.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1-13 A compact coil traction and longitudinal cutting integrated mechanism includes a backboard 1, a transmission mechanism 2, a front traction mechanism 3, a longitudinal cutting mechanism 4 and a rear traction mechanism 5; the front side wall of the backboard 1 is respectively connected to the front traction mechanism 3, the longitudinal cutting mechanism 4 and the rear traction mechanism 5; the transmission mechanism 2 is arranged on the rear side wall of the backboard 1, and is respectively connected to the front traction mechanism 3, the longitudinal cutting mechanism 4 and the rear traction mechanism 5.

[0040] See also Figure 5 、 67. The front traction mechanism 3 includes a front traction mounting frame 31, a first upper traction roller 32, and a first lower traction roller 33. The first upper traction roller 32 and the first lower traction roller 33 are both mounted on the front traction mounting frame 31 and connected to each other via a first gear set 34. A traction anti-deviation mechanism 37 is connected to the front traction mounting frame 31.

[0041] See also Figure 5 、 6 , 7. The front traction mechanism 3 also includes two first power cylinders 35, which are connected to the front traction mounting frame 31. The two ends of the first upper traction roller 32 are rotatably connected to the first slider 36, and the two first sliders 36 are connected to the output ends of the two first power cylinders 35.

[0042] Specifically, the first upper traction roller 32, powered by the first power cylinder 35, presses the web between the first upper traction roller 32 and the first lower traction roller 33, and conveys the web by friction between the first upper traction roller 32 and the first lower traction roller 33. The material and shape of the first upper traction roller 32 and the first lower traction roller 33 can be changed according to the web material.

[0043] Specifically, the first power cylinder 35 can ensure that the traction roller can be fully pressed. The positive pressure between the upper and lower traction rollers can be adjusted by adjusting the air pressure.

[0044] Specifically, the first upper traction roller 32 and the first lower traction roller 33 are connected via the first gear set 34 , which can ensure sufficient driving force without slipping, and can deliver the coil more effectively.

[0045] Specifically, the front traction mechanism 3 is the primary traction for the entire mechanism. The primary traction force must be greater than the other traction forces to ensure traction accuracy. Therefore, the power of the front traction mechanism 3 can be increased by adjusting the roller material, roller surface treatment, roller pressure force, and whether upper and lower dual-drive gears are configured. If the front traction is the primary traction, the traction force can be increased using the methods described above, while the rear traction force needs to be appropriately weakened.

[0046] See also Figure 8 、 9 10. The slitting mechanism 4 includes a slitting mounting plate 41, an upper slitting roller 42, and a lower slitting roller 43. The upper slitting roller 42 and the lower slitting roller 43 are mounted on the slitting mounting plate 41, respectively. The upper slitting roller 42 and the lower slitting roller 43 are connected via a third gear set 46. A guide comb plate 44 is provided between the upper slitting roller 42 and the lower slitting roller 43. A slitting anti-deviation mechanism 45 is provided between the upper slitting roller 42 and the lower slitting roller 43.

[0047] Specifically, the upper slitting roller 42 and the lower slitting roller 43 are connected via a third gear set 46 , which can ensure sufficient driving force without slipping, and can deliver the coil more effectively.

[0048] Specifically, the annular projections and grooves on the upper and lower slitting rollers 42 and 43 engage with each other under the pressure of the slitting rollers, forming a shear cut along the direction of the coil's motion as the coil is rotated and delivered. This shearing process allows the coil to be precisely processed to the desired size with burr-free edges.

[0049] Specifically, the slitting rollers can be manufactured as a single piece or as a multi-layered ring, each cutter ring individually secured axially with end caps and nuts. This method avoids machining the internal groove and facilitates changing the width of the slitting rollers. To facilitate material feeding during work preparation, the slitting rollers must be able to be lifted. This can be driven by a pneumatic cylinder or a motor. If using a pneumatic drive, a buffer can be added to prevent severe impact.

[0050] See also Figure 11 、 12 , 13, the rear traction mechanism 5 includes a rear traction mounting frame 51, a second upper traction roller 52 and a second lower traction roller 53; the second upper traction roller 52 and the second lower traction roller 53 are both arranged on the rear traction mounting frame 51, and the second upper traction roller 52 and the second lower traction roller 53 are connected by a second gear set 54.

[0051] See also Figure 11 、 12 , 13, the rear traction mechanism 5 also includes two second power cylinders 55, the two second power cylinders 55 are connected to the rear traction mounting frame 51, the two ends of the second upper traction roller 52 are rotatably connected to the second slider 56, and the two second sliders 56 are connected to the output ends of the two second power cylinders 55.

[0052] Specifically, the second power cylinder 55 can ensure that the traction roller can be fully pressed. The positive pressure between the upper and lower traction rollers can be adjusted by adjusting the air pressure.

[0053] Specifically, the second upper traction roller 52 and the second lower traction roller 53 are connected via the second gear set 54, which can ensure sufficient driving force without slipping, and can deliver the coil more effectively.

[0054] Specifically, the diameter of the traction roller of the rear traction mechanism 5 can be slightly larger than that of the front traction roller. To avoid slitting deviations, it is necessary to ensure that the coil is taut during slitting. Because multi-stage transmission inevitably results in transmission errors and the coil may stretch during processing, the coil may become loose before and after slitting after long-term operation. Properly increasing the linear displacement of the rear traction can ensure the coil is taut. As long as the rear traction coil diameter is appropriately increased and the traction force is reduced, there will be no significant impact on the coil.

[0055] See also Figure 4The transmission mechanism 2 includes a transmission mounting plate 21, a first synchronous belt set 22 and a second synchronous belt set 23. One end of the first synchronous belt set 22 is connected to the first lower traction roller 33, and the other end is connected to the lower slitting roller 43; one end of the second synchronous belt set 23 is connected to the lower slitting roller 43, and the other end is connected to the second lower traction roller 53;

[0056] Specifically, the first synchronous belt set 22 is connected to a first tensioning pulley 26, and the second synchronous belt set 23 is connected to a second tensioning pulley 27, which are used to tension the synchronous belts to ensure transmission consistency.

[0057] Specifically, the transmission mechanism 2 further includes a power mounting frame 24 , which is connected to the transmission mounting plate 21 . The power mounting frame 24 is connected to a drive motor 25 , and an output end of the drive motor 25 is connected to one end of the first synchronous belt set 22 .

[0058] Specifically, in addition to using the first synchronous belt set 22 and the second synchronous belt set 23 for transmission, various transmission forms such as gear transmission and chain transmission can also be used to ensure that one power source is used for driving.

[0059] Specifically, multiple power sources may be selected and precisely controlled to simultaneously drive the first lower traction roller 33 , the lower slitting roller 43 , and the second lower traction roller 53 .

[0060] Specifically, the materials of the first upper pulling roller 32, the first lower pulling roller 33, the second upper pulling roller 52, and the second lower pulling roller 53 can be changed as needed. Common materials include metal, plastic, PU, ​​silicone, etc. The shape of the rollers can also be adjusted as needed. If necessary, some air gap design can be added to avoid the characteristics of the coil (such as an annular air gap to prevent damage to the blisters processed upstream).

[0061] Specifically, to ensure accurate pulling, the first and second lower pulling rollers 33 and 53 can be made of high-hardness, high-precision rollers, such as aluminum alloy or steel. Because the circumference of such rollers is stable and precise, linear displacement can be obtained through rotation angles. To increase roller friction, the roller surfaces can also be treated with printing, textured, or sandblasted.

[0062] Specifically, to ensure accurate traction, sufficient traction force is required, so the first upper traction roller 32 and the second upper traction roller 52 can be rubber rollers to increase friction.

[0063] Specifically, the driving motor 25 drives the first synchronous belt group 22 and the first lower traction roller 33 to rotate, the first lower traction roller 33 rotates through the first gear group 34 to drive the first upper traction roller 32 to rotate, and at the same time the first synchronous belt group 22 drives the lower slitting roller 43 to rotate, the lower slitting roller 43 rotates through the third gear group 46 to drive the upper slitting roller 42 to rotate, and at the same time the lower slitting roller 43 rotates through the second synchronous belt group 23 to drive the second lower traction roller 53 to rotate, the second lower traction roller 53 rotates through the second gear group 54 to drive the second upper traction roller 52 to rotate, the coil enters from between the first lower traction roller 33 and the first upper traction roller 32, and then to between the lower slitting roller 43 and the upper slitting roller 42. After slitting, the material is discharged from between the second lower traction roller 53 and the second upper traction roller 52 and enters the next process.
