Description

Technical Field

[0001] This invention relates to the field of aluminum foil tape slitting technology, specifically to an aluminum foil tape unwinding and cutting device and the aluminum foil tape produced by the device. Background Technology

[0002] Aluminum foil tape uses high-quality pressure-sensitive adhesive, offering excellent adhesion, strong bonding, and anti-aging properties. It significantly improves thermal insulation performance and is available in various widths and lengths (0.05mm-0.08mm). Aluminum foil tape is suitable for bonding seams in all aluminum foil composite materials, sealing punctures from insulation nails, and repairing damaged areas.

[0003] In the existing production, slitting, and packaging process of aluminum foil tape, the steps are as follows: the large roll of aluminum foil tape is rolled onto a paper sleeve, cut according to the length of a single roll of aluminum foil tape, and then the sleeve is cut according to the required width of a single roll of aluminum foil tape.

[0004] However, in existing technologies, the paper sleeves on the receiving rolls can easily damage the receiving rolls during slitting. Additionally, the aluminum foil tape has strong adhesion, resulting in small gaps between adjacent tapes after slitting. This causes impurities to adhere to these gaps, and adhesive overflows along the slitting surface. As air enters the gaps and oxidizes, the adhesive solidifies, making it difficult to separate adjacent slitting rolls of aluminum foil tape. Furthermore, after single-segment slitting, one end of the sleeve becomes a free end, requiring additional support in subsequent slitting processes; otherwise, slitting errors can easily increase.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 11 The present invention provides a technical solution:

[0034] Example 1: An aluminum foil tape unwinding and cutting device, the cutting device includes a cutting frame 1, an unwinding roller 2 and a winding frame 10 are provided on the cutting frame 1, a winding slitting roller 3 driven by a winding motor 12 is provided on the winding frame 10, a side frame 13 is provided on one side of the winding slitting roller 3, multiple sets of linearly distributed adjusting blocks 27 are fixedly installed on the outer wall of the winding slitting roller 3, and a sleeve 14 is fixedly sleeved on the winding slitting roller 3.

[0035] The sleeve 14 is fixed at one end by the side frame 13, thereby achieving the installation of the sleeve 14 with one end fixed and the other end split. The large roll of aluminum foil tape is split and wound onto the sleeve 14 by the unwinding roller 2 and the winding frame 10.

[0036] The cutting frame 1 is equipped with three sets of guide rollers spaced at equal heights. A movable roller 6 with lifting and sliding installation is provided between a pair of guide rollers near the unwinding roller 2. A limit pressure frame 5 driven by an electric telescopic rod is provided at the upper end of a pair of guide rollers near the winding frame 10. The lower end of the limit pressure frame 5 is pressed against the upper outer wall of the guide roller. A cutting blade 4 for cutting is provided between the winding frame 10 and the guide roller.

[0037] During the slitting process, the downward gravity of the movable roller 6 is used to tighten and flatten the aluminum foil tape. When the tape is slitted to the required length for a single roll, it is cut with the cutting blade 4 to obtain the specified length of aluminum foil tape. During the cutting process, the limiting pressure frame 5 descends and presses the aluminum foil tape onto the guide roller to prevent the aluminum foil tape from becoming loose due to lack of traction after cutting and the gravity of the movable roller 6.

[0038] An inner liner tube 21 is fixedly sleeved in the inner cavity of the winding and slitting roller 3. Linearly distributed through holes 49 are provided on the arc-shaped outer wall of the winding and slitting roller 3. An insertion hole 50 communicating with the through holes 49 is provided at the end of the winding and slitting roller 3. An arc groove 9 corresponding to the adjusting block 27 is provided on the outer wall of the inner liner tube 21. A traction arc plate 29 is rotatably installed on the arc groove 9.

[0039] The limit rotation adjustment of the traction arc plate 29 is achieved by setting the arc groove 9.

[0040] One side of the adjusting block 27 is telescopically connected to the top holding box 25. The adjusting block 27 is equipped with a traction assembly for sliding the top holding box 25. The other end of the traction assembly is connected to the traction arc plate 29. A pair of piston rods 42 are symmetrically arranged at the lower end of the top holding box 25, abutting against the outer arc of the winding and slitting roller 3. A T-shaped piston rod 43 is arranged between adjacent pairs of piston rods 42. The pistons at the ends of the T-shaped piston rod 43 and the piston rods 42 are slidably installed in the inner cavity of the top holding box 25. An airbag 32 is provided at the upper end of the sleeve 14, and a top holding inclined plate 31 is provided at the upper end of the airbag 32. The top holding inclined plate 31 abuts against the inner wall of the sleeve 14. A sliding sliding frame 15 is slidably inserted at the other end of the winding slitting roller 3. A limiting insert 23 is provided on the sliding sliding frame 15 and inserted into the insertion hole 50. A rotating insert 22 is provided on the sliding sliding frame 15 and inserted into the inner liner tube 21. The ends of the limiting insert 23 and the rotating insert 22 are both provided with a pneumatic device for driving traction components and T-shaped piston rod 43.

[0041] By sliding the sliding frame 15, the positions of the ends of the rotating insert 22 and the limiting insert 23 are adjusted so that their ends are close to the adjusting block 27 closest to the sliding position. Then, the pneumatic device drives the traction arc plate 29 driven by the rotating insert 22 to rotate, causing the top holding box 25 to slide towards the adjusting block 27. This causes the T-shaped piston rod 43 to be aligned with the through hole 49. At this time, the end of the limiting insert 23 extends and squeezes the T-shaped piston rod 43, increasing the internal pressure of the top holding box 25. This drives the piston rod 42 to press down and abut against the outer wall of the winding sliding roller 3. This creates an opposing compression between the airbag 32 and the piston rod 42, which secures the top holding box 25 between the sleeve 14 and the winding sliding roller 3, thus fixing and supporting the sleeve 14. This improves the support strength at the sliding position, prevents deformation of the free end due to sliding compression, and ensures the accuracy of sliding.

[0042] Working principle: The aluminum foil tape preparation process includes slitting, cutting, and splitting. Slitting involves rolling the large roll of aluminum foil tape onto the paper sleeve 14. Cutting involves cutting the length of a single roll of aluminum foil tape. After cutting, the width of a single roll of aluminum foil tape is obtained by splitting.

[0043] During the sliding process, the position of the sliding blade 17 is adjusted by sliding the sliding frame 15, so that the position of the sliding blade 17 is the same as the required sliding width. After adjustment, the ends of the rotating insert tube 22 and the limiting insert tube 23 are close to the adjusting block 27 closest to the sliding position. At this time, the rotating insert tube 22 drives the traction assembly to drive the top holding box 25 to slide towards the adjusting block 27. Due to the support of the top holding box 25, a sliding gap is left between the sleeve 14 and the winding sliding roller 3, which facilitates the sliding of the sleeve 14. After sliding, the T-shaped piston rod 43 is aligned with the through hole 49. The limiting insert tube 23 squeezes the T-shaped piston rod 43, which increases the internal pressure of the top holding box 25, forming a tight support for the sleeve 14 and the winding sliding roller 3.

[0044] At this time, the slitting blade 17 descends and performs slitting. After slitting, the rotating insertion tube 22 and the limiting insertion tube 23 are reset. Under the action of the spring, the top holding box 25 is driven to slide. Due to the contact between the top holding inclined plate 31 and the sleeve 14, the single roll of aluminum foil tape after slitting is driven to separate under the action of friction, which increases the slitting gap, making it easier to clean the impurities in the gap after slitting. At the same time, it separates adjacent aluminum foil tape rolls, avoiding the problem of glue seeping out from the gap between adjacent aluminum foil tape rolls sticking together and making it difficult to separate.

[0045] Example 2: Based on Example 1, in order to drive the limiting insertion tube 23 and the rotating insertion tube 22, a winding frame 10 is slidably mounted on the lower end of the sliding slitting frame 15, a motor-driven slitting blade 17 is provided on the upper end of the sliding slitting frame 15, the rotating insertion tube 22 is rotatably mounted on the sliding slitting frame 15, a gear drive 19 is provided on the sliding slitting frame 15 to drive the rotating insertion tube 22 to rotate, a second air pump 20 and a first air pump 18 are respectively provided at the ends of the rotating insertion tube 22 and the limiting insertion tube 23 near the end of the sliding slitting frame 15, the pneumatic device is a telescopic protrusion 38, the second air pump 20 and the first air pump 18 drive the telescopic protrusion 38 to extend and slide, a groove 39 is provided on the inner wall of the traction arc plate 29, the telescopic protrusion 38 at the end of the rotating insertion tube 22 is inserted into the groove 39, and the telescopic protrusion 38 at the end of the limiting insertion tube 23 is inserted into the insertion hole 50.

[0046] The telescopic protrusion 38 is extended by the air pump, and then the limiting tube 23 is connected to the traction arc plate 29 by the insertion of the telescopic protrusion 38. Under the drive of the gear drive component 19, rotational traction is achieved, and at the same time, the limiting tube 23 squeezes the T-shaped piston rod 43.

[0047] Example 3: Based on Example 2, in order to achieve convenient installation and cutting, the side of the top holding inclined plate 31 that is inserted into the sleeve 14 is set as an inclined surface, a crossbar 44 is provided on one side of the outer wall of the top holding box 25, a horizontal tube 48 is provided on one side of the adjusting block 27, a steering wheel 16 is provided in the inner cavity of the adjusting block 27, a second pull rope 47 is provided in the inner cavity of the adjusting block 27, one end of the second pull rope 47 is connected to the crossbar 44, the middle section of the second pull rope 47 extends smoothly and vertically downward along the steering wheel 16 and is connected to the traction component, the other end of the traction component is fixedly connected to the traction arc plate 29, a limiting arc rod 11 is provided in the arc groove 9, and the traction arc plate 29 is slidably sleeved on the limiting arc rod 11.

[0048] By setting a top holding inclined plate 31 with one side inclined, the initial installation of the sleeve 14 is facilitated, so that the sleeve 14 slides along the inclined surface to fit and squeeze the air bag 32, realizing the convenient fitting of the sleeve 14 on the winding and sliding roller 3. At this time, the top holding inclined plate 31 slides and squeezes against the inner wall of the sleeve 14. The top holding box 25 is telescopically inserted by using the connection of the horizontal tube 48 and the horizontal bar 44. The rotation position of the traction arc plate 29 is limited by the limiting arc rod 11.

[0049] The traction assembly includes a first connecting block 45, a second connecting block 46, a first pull rope 37, and a pressure plate 34. A circular gap groove is provided between the winding and slitting roller 3 and the inner liner tube 21. A second spring 36 is provided at the upper end of the traction arc plate 29. The second spring 36 is sleeved on the first pull rope 37. The lower end of the first pull rope 37 is fixed on the traction arc plate 29. The upper end of the first pull rope 37 is connected to the pressure plate 34. A connecting rod 7 is provided at the upper end of the pressure plate 34. The two ends of the second pull rope 47 are respectively connected to the first connecting block 45 and the second connecting block 46. The first connecting block 45 is connected to the connecting rod 7, and the second connecting block 46 is connected to the crossbar 44.

[0050] The second spring 36 enables an elastic connection between the pressure plate 34 and the traction arc plate 29.

[0051] A first spring 33 is sleeved on the outside of the crossbar 44 and the horizontal tube 48. The two ends of the first spring 33 abut against the outer walls of the adjusting block 27 and the top holding box 25, respectively. The crossbar 44 is threadedly connected to the second connecting block 46. One end of the second connecting block 46 is inserted into the horizontal tube 48. A rotating block is rotatably mounted on the end bearing of the second connecting block 46. The rotating block is connected to the second pull rope 47.

[0052] A rotating block is used to achieve a threaded rotational connection between the crossbar 44 and the second connecting block 46, while preventing the second pull rope 47 from rotating during the threaded rotational connection process.

[0053] Multiple sets of linearly distributed second cross slots 41 are provided on the outer wall of the winding and slitting roller 3. The end of the first connecting block 45 is provided with a first cross slot 40. A round hole is provided between the first cross slot 40 and the second cross slot 41. A cross slot is provided on the outer side of the round hole. An inner groove with the same outer diameter as the slot is provided on the inner side of the round hole. The ends of the connecting rod 7 and the adjusting block 27 are respectively provided with a first cross block 8 and a second cross block 30. The first cross block 8 and the second cross block 30 are respectively inserted into the first cross slot 40 and the second cross slot 41.

[0054] By setting up a cross-shaped slot and a cross-shaped block to cooperate, the adjustment block 27 can be easily installed.

[0055] During the actual installation of the slitting equipment, the traction component is installed on the inner liner tube 21, and the inner liner tube 21 is installed in the winding slitting roller 3. Then, according to the required width of the single roll of aluminum foil tape, the adjusting block 27 is installed. The installation of the adjusting block 27 only requires inserting it along the cross slot and then rotating the cross block in a staggered manner. The installation is convenient. At the same time as the insertion installation, the connecting rod 7 is connected to the first connecting block 45. Then, the sleeve 14 is squeezed along the top holding inclined plate 31 and one end of the sleeve 14 is fixed.

[0056] After slitting, the sleeve 14 wrapped with aluminum foil tape can be removed directly. During subsequent slitting, the positions of the adjusting block 27 and the top holding box 25 can be adjusted according to the slitting width. The installation and removal of the adjusting block 27 and the top holding box 25 can be done simply by plugging and rotating, which is convenient and quick. With the sliding adjustment of the sliding sliding frame 15, the width of a single roll of aluminum foil tape can be precisely controlled.

[0057] Example 4: Based on Example 3, in order to avoid the rotation of the connecting rod 7 during the installation and insertion rotation, a pair of side rods 35 are symmetrically arranged on the upper outer edge of the pressure plate 34, and a limit slot 28 is provided on the inner wall of the winding and slitting roller 3, and the side rods 35 are slidably inserted into the limit slot 28.

[0058] By using the insertion of the side rod 35 into the limiting slot 28, the circumferential rotation of the pressure plate 34 is limited, ensuring its vertical lifting and lowering.

[0059] Example 5: Based on Example 3, in order to achieve the fixed installation of one end of the sleeve 14, a circular groove 24 is provided on one side wall of the side frame 13, one end of the sleeve 14 is inserted into the circular groove 24, and a locking bolt 26 is provided on the side wall of the side frame 13, one end of the locking bolt 26 extends into the circular groove 24 and is pressed against the outer wall of the end of the sleeve 14.

[0061] An aluminum foil tape is cut using an aluminum foil tape unwinding and cutting device. The aluminum foil tape includes an aluminum foil layer, a tensile layer, a flame retardant layer, a waterproof layer, and an adhesive layer. One end of the aluminum foil tape is wound around an unwinding roller 2, the middle section of the aluminum foil tape extends smoothly along a cutting frame 1, and the other end of the aluminum foil tape is wound around a sleeve 14.
