Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tape rewinders, in particular to an aluminum foil tape rewinder with a flattening structure. Background Art
[0002] Aluminum foil tape is a special tape with aluminum foil as the main body and pressure-sensitive adhesive coated on the back. It has the advantages of good viscosity, strong adhesion, and anti-aging. It is widely used in refrigerators, air conditioners, automobiles, petrochemicals, bridges, hotels, electronics and other industries.
[0003] Rewinding is the process of dividing a large roll of aluminum foil tape into multiple small rolls. During this process, the large roll of tape needs to be unwound and rewound, which is usually done using a tape rewinder. The common tape rewinders on the market are mostly similar in structure. A large roll of tape is put on the feeding roller, and the tape is pulled through the limit shaft and guide shaft and then attached to the paper drum. The roller where the paper drum is located is driven by a motor to rotate, and the tape is continuously wound on it. There are some functional deficiencies in actual use, and there is room for improvement. For example, during the rewinding process, the tape needs to be straightened by pressure rods, rollers and other components. When there are wrinkles on the surface of the tape, it is easy to be directly rolled in during the winding process, so that the rolled tape has a hollow part, which affects the final product appearance and does not have the function of flattening the tape surface.
[0004] Now, a new type of aluminum foil tape rewinder with a flattening structure is proposed to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present invention are: the aluminum foil tape rewinder with a flattening structure not only realizes the function of flattening the tape surface, but also realizes the function of facilitating the adjustment of the limit position and the function of adjusting the tape tension;

When in use, a large roll of tape is directly put on the third roller for fixing, and the tape head is pulled out. The tape passes under the tape pressure rod, then passes over the second roller, and adheres to the paper drum on the first roller.

Obviously, the embodiments described 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.
[0025] Example 1: Please refer to Figure 1-4 , an aluminum foil tape rewinder with a flattening structure, comprising a bottom shell 1, a control panel 2 is provided at the top of the front end of the bottom shell 1, a top shell 3 is fixedly connected to the rear end of the top of the bottom shell 1, a first drive motor 4 is installed on the right side of the front end of the top shell 3, a first roller 5 is movably connected to the right side of the front end of the top shell 3, a second drive motor 6 is installed at the middle position of the top of the front end of the top shell 3, a second roller 7 is movably connected to the middle position of the top of the front end of the top shell 3, a tape pressure rod 14 is fixedly connected to the left side of the front end of the top shell 3, and a flattening component that can flatten the wrinkles on the surface of the aluminum foil tape is provided at the middle position of the top end of the top shell 3;
[0026] See also Figure 1-4 , an aluminum foil tape rewinder with a flattening structure also includes a flattening assembly, which includes an upper fixed plate 8, which is fixedly connected to the middle position of the top of the top shell 3, a first electric cylinder 9 is installed at the front end of the top of the upper fixed plate 8, and a lower pressing plate 10 is provided below the upper fixed plate 8. The four corners of the top of the lower pressing plate 10 are vertically welded with limit rods 11, and roller mounting frames 12 are welded on both sides of the bottom end of the lower pressing plate 10. A flattening roller 13 is movably connected between the front and rear ends of the roller mounting frame 12;
[0027] The bottom end of the first electric cylinder 9 is connected to the bottom end of the lower pressing plate 10. There is a distance between the rear end of the lower pressing plate 10 and the front end of the top shell 3. The limiting rod 11 passes through the interior of the upper fixed plate 8 and extends to the outside. The limiting rod 11 can slide up and down along the interior of the upper fixed plate 8. The distance between the two sets of flattening rollers 13 is smaller than the cross-sectional diameter of the second rotating roller 7. The flattening rollers 13 are symmetrically distributed about the vertical center line of the lower pressing plate 10, which can flatten the tape.
[0028] Specifically, if Figure 1 and Figure 3 As shown, the first electric cylinder 9 on the top of the upper fixed plate 8 extends downward, pushing the lower pressure plate 10 downward, and the roller mounting frame 12 moves downward. At the same time, the flattening roller 13 is pressed on the top of the second roller 7, cooperating with the second roller 7 to flatten the surface of the aluminum foil tape. The limiting rod 11 can make the lower pressure plate 10 slide up and down smoothly.
[0029] Example 2: A lower groove 15 is provided at the top of the tape pressure rod 14, and a damping tape 16 is glued to the bottom end of the lower groove 15. An adjusting ring 18 is sleeved on the outside of the tape pressure rod 14. A limit ring 17 is welded to the opposite ends of the two sets of adjusting rings 18. A hand-tightening bolt 19 is inserted at the top of the adjusting ring 18. The inner diameter of the adjusting ring 18 is adapted to the outer diameter of the tape pressure rod 14. The adjusting ring 18 can slide back and forth along the outside of the tape pressure rod 14 to facilitate the limit adjustment of the tape;
[0030] Specifically, if Figure 1 and Figure 2 As shown, loosen the hand-tightening bolt 19. After the hand-tightening bolt 19 and the damping tape 16 are no longer in contact, the adjusting ring 18 together with the limiting ring 17 can be moved forward and backward along the tape pressure rod 14. After adjusting to the appropriate position, tighten the hand-tightening bolt 19. The hand-tightening bolt 19 presses against the damping tape 16 in the lower groove 15, and the position of the adjusting ring 18 together with the limiting ring 17 is fixed.
[0031] Example 3: Two sets of second electric cylinders 22 are installed inside the left side of the top of the bottom housing 1. A right-angle steel frame 20 is set above the bottom housing 1. The top of the front end of the right-angle steel frame 20 is movably connected to the third roller 21. The top of the second electric cylinder 22 is connected to the bottom end of the right-angle steel frame 20. The rear end of the right-angle steel frame 20 is flush with the front end of the top housing 3, so that the tape tension can be adjusted during the rewinding process.
[0032] Specifically, if Figure 1 and Figure 4 As shown, as the diameter of the large roll continues to decrease, the second electric cylinder 22 continues to extend upward, pushing the right-angle steel frame 20 and the third roller 21 to move upward synchronously, so that the tension of the tape remains constant.
[0033] Working principle: When the present invention is in use, first, the large roll of tape is directly put on the third roller 21 for fixing, and the tape head is pulled out. The tape passes under the tape pressure rod 14, and then passes over the second roller 7, and is attached to the paper drum on the first roller 5. The first drive motor 4 drives the first roller 5 to rotate continuously, and the tape is continuously pulled and wound on the paper drum. During the winding process, the first electric cylinder 9 on the top of the upper fixed plate 8 extends downward, pushing the lower pressure plate 10 to move downward, and the roller mounting frame 12 moves downward. At the same time, the flattening roller 13 is pressed on the top of the second roller 7, and cooperates with the second roller 7 to flatten the tape surface of the aluminum foil tape. The limit rod 11 can make the lower pressure plate 10 slide up and down smoothly. The distance between the two sets of limit rings 17 can be adjusted according to the width of the tape. Once the thumb bolts 19 are loosened and the damping tape 16 is no longer in contact, the adjustment ring 18, along with the limit rings 17, can be moved forward and backward along the tape pressure bar 14. Once the desired position is reached, the thumb bolts 19 are tightened, pressing against the damping tape 16 in the lower groove 15. This secures the position of the adjustment ring 18 and the limit rings 17. The large roll of tape is directly secured on the third roller 21. During the rewinding process, as the diameter of the large roll decreases, the second electric cylinder 22 continues to extend upward, pushing the right-angle steel frame 20 and the third roller 21 upward synchronously to maintain constant tape tension.
[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
