Description

Technical Field

[0001] This utility model belongs to the field of aluminum plate winding technology, specifically relating to an auxiliary device for aluminum plate winding. Background Technology

[0002] Stretch straightening and slitting are common processing methods in the metal processing industry. After stretch straightening or slitting, aluminum sheets need to be rewound. When using paper cores to rewind aluminum sheets, the sheet head is prone to lifting and damaging subsequent materials, forming transverse creases. These creases can affect the normal use of downstream processes and easily result in a large amount of scrap.

[0003] Currently, the conventional method of assisting winding involves attaching the sprue to the paper core or slotted paper core with tape, followed by winding. However, directly attaching the sprue to the paper core does not reduce the impact of the sprue on the thickness of the material and easily causes creases. Using slotted paper cores can reduce some of the waste due to creases on the inner ring, but it is easily affected by factors such as the quality of the paper core and the operation of the underlayment personnel, which can lead to downstream customers being unable to use it normally, as well as an increase in ineffective output of the processing steps and wasted costs.

[0004] Therefore, there is an urgent need for an auxiliary device for aluminum sheet winding to reduce the generation of creases on the inner ring of the coil. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an auxiliary device for aluminum plate winding, which aims to solve the problem that creases are easily formed during the aluminum plate winding process, resulting in increased ineffective output and wasted costs.

[0006] The present invention solves the above problems by adopting the following technical solution:

[0007] An auxiliary device for coiling aluminum sheets includes a base plate and a wool felt. A cylinder is mounted on the base plate. A limiting groove is formed in the middle of the base plate. A limiting block is slidably connected in the limiting groove. A horizontally placed Y-shaped frame is fixedly connected to the upper end of the limiting block extending out of the limiting groove. The telescopic end of the cylinder is fixedly connected to the horizontal section of the Y-shaped frame. Support columns are fixedly connected to the free ends of the two inclined sections of the Y-shaped frame. A bracket is fixedly connected to the upper end of each support column. A sliding groove is formed on the bracket. A slider is slidably connected in the sliding groove. A through hole communicating with the sliding groove is formed on the free end of the bracket. A steel wire passing through the corresponding through hole is provided on the slider. Ropes are provided at both ends of the upper side of the wool felt. The free ends of the two ropes are fixedly connected to the free ends of the corresponding steel wires, respectively.

[0008] It also includes a paper core that cooperates with the roller for winding the aluminum plate. A set of corresponding foam adhesive is fixedly connected to both ends of the circumferential side of the paper core. A tape of the same width as the paper core is fixedly connected to one side of the foam adhesive. Release paper is provided on the adhesive surface of both the foam adhesive and the tape. The foam adhesive and the tape are used to fix the end of the aluminum plate to be wound.

[0009] Furthermore, the support column is an electrically telescopic column.

[0010] This structural design allows for flexible adjustment of the support column height according to needs, making it more versatile.

[0011] Furthermore, a clamp is fixedly connected to the end of the steel wire away from the slider through the through hole, and the clamp is used to clamp and fix the free end of the rope.

[0012] This structural design allows for quick clamping and securing of the wool felt, making wool felt replacement easier.

[0013] Furthermore, the bracket is rotatably connected to the upper end of the support column, and a locking bolt is installed on the support column to abut against and fix the bracket.

[0014] This structural design allows for flexible adjustment of the bracket's deflection angle according to needs, making it more versatile.

[0017] 2.

[0023] Our staff discovered during the aluminum sheet winding process that when the aluminum material wraps around approximately 3 / 4 of the paper core 11, placing a felt pad 2 on top and then driving the roll to rotate twice to loosen the tension; after that, reversing the winding, removing the felt pad 2, and then slowly jogging the roll to tighten the strip. This changes the force distribution during contact, significantly reducing the initial crease. However, the placement and removal of the felt pad 2 is quite inconvenient, severely affecting the aluminum sheet winding efficiency. To address this issue, this invention designs an auxiliary device for aluminum sheet winding.

A limit groove is opened in the middle of the upper side of the base plate 1. A limit block 4 is slidably connected in the limit groove. The upper end of the limit block 4 extends out of the limit groove and is fixedly connected to a horizontally placed Y-shaped frame 5. The telescopic end on the right side of the cylinder 3 is fixedly connected to the horizontal section of the Y-shaped frame 5. Vertically arranged support columns 6 are fixedly connected to the free ends of the two inclined sections of the Y-shaped frame 5. A bracket 7 is fixedly connected to the upper end of the support column 6. A sliding groove is opened on the bracket 7. A slider 8 is slidably connected in the sliding groove. A through hole communicating with the sliding groove is opened at the free end of the bracket 7. A steel wire 9 passing through the corresponding through hole is fixedly connected to the slider 8. Ropes 10 are fixedly connected to both ends of the upper side of the wool felt 2. The free ends of the two ropes 10 are fixedly connected to the free ends of the corresponding steel wires 9 respectively.

[0025] The auxiliary device of this utility model also includes a paper core 11 that cooperates with the roller for winding the aluminum plate. A set of corresponding foam adhesive 12 is fixedly connected to both ends of the circumferential side of the paper core 11. A tape 13 with the same width as the paper core 11 is provided on the right side of the foam adhesive 12 and is fixedly connected to the paper core 11. Release paper is provided on the adhesive surface of both the foam adhesive 12 and the tape 13. The foam adhesive 12 and the tape 13 are used to fix the material head of the aluminum plate to be wound.

[0026] As a preferred embodiment, the support column 6 is an electrically telescopic column.

[0027] As a preferred embodiment, the end of the steel wire 9 away from the slider 8 is fixedly connected to a clip through the through hole. The clip is used to clamp and fix the free end of the rope 10.

[0028] As a preferred embodiment, the bracket 7 is rotatably connected to the upper end of the support column 6, and a locking bolt is installed on the support column 6 to abut and fix the bracket 7.

[0029] As a preferred embodiment, the thickness formula of the foam adhesive is: X=H+(0.5~2)mm, where X represents the thickness of the foam adhesive and H represents the thickness of the aluminum plate, with an allowable deviation of 0.5~2mm; the width formula is: Y=50±5mm, where Y represents the width of the foam adhesive.

[0030] As a preferred embodiment, the thickness formula of the wool felt is: Z=H+(2~4)mm, where Z represents the thickness of the wool felt and H represents the thickness of the aluminum plate, with an allowable deviation of 2~4mm; the width of the wool felt is 150-300mm.

[0031] When the aluminum sheet needs to be wound up, first place the paper core 11 on the winding roller, with the foam adhesive 12 on the paper core 11 facing upwards. Then, peel off the release paper on the upper side of the foam adhesive 12 and stick the aluminum sheet to be wound onto the foam adhesive 12, with the foam adhesive 12 10-20mm away from the aluminum sheet head, and the edge of the foam adhesive 12 parallel to the head. Then, peel off the release paper of the tape 13 and use the tape 13 to fix the aluminum sheet head, ensuring the tape 13 is applied smoothly without wrinkles. Next, start the motor to drive the roller to rotate, which in turn drives the paper core 11 to rotate synchronously, thereby winding up the aluminum sheet. When the aluminum sheet has wrapped about 3 / 4 of the circumference of the paper core 11, turn off the motor, and the roller stops rotating. Then, adjust the height of the support column 6 and the deflection angle of the bracket 7 so that the upper end of the felt 2 and the upper end of the paper core 11 are on the same horizontal plane. After adjustment, the telescopic end of cylinder 3 extends, driving the Y-shaped frame 5 to move along the limiting groove towards the paper core 11 until the upper end of the wool felt 2 is in close contact with the paper core 11. Then, the motor is started, driving the roller and paper core 11 to rotate, rewinding the aluminum plate. After the roller winds for two turns, tension is applied, then the winding is reversed, allowing the wool felt 2 to reset under gravity. After the wool felt 2 resets, the telescopic end of cylinder 3 retracts, moving the wool felt 2 away from the roller to avoid affecting subsequent winding. After moving the wool felt 2 outward, the motor is started, and slow, intermittent winding is performed to tighten the strip. This auxiliary device, through the foam adhesive 12 and the wool felt 2, changes the force position during contact, preventing material warping and damage to the next turn, thus reducing inner ring creases.
