[0032] The roller 11 is equipped on the frame body 1, and the brake assembly is equipped at the position corresponding to the roller 11 on the frame body 1, the brake assembly includes the bottom plate 12 arranged on the frame body 1 and the clamping sleeve 13 hingedly connected with the bottom plate, the section of the clamping sleeve 13 is a concave circular arc structure, and two rubber blocks 15 are symmetrically arranged on the inner side wall of the circular arc structure.

[0033] One side of the clamping sleeve 13 is provided with a tension spring 14, one side of the tension spring 14 is fixedly connected with the outer side wall of the clamping sleeve 13, and the other side of the tension spring 14 is fixedly connected with the bottom plate 12.

[0034] The lifting assembly includes a first linear motor 3 fixed on the frame 1 and a support block 31 connected to the output end of the first linear motor 3 and extending upward. The support block 31 has a concave arc-shaped structure, and a buffer pad 32 is provided on the inner side wall of the arc-shaped structure. The lifting assembly also includes a proximity switch 33 and a speed sensor 34 installed on the frame 1 and connected to the PLC controller 4. One side of the PLC controller 4 is electrically connected to the battery 40, and the other side is electrically connected to the first linear motor 3.

[0035] The clamping assembly includes a second linear motor 5 mounted on the support frame 10 and connected to the PLC controller 4, and a connecting frame 50 connected to the output end of the second linear motor 5. A connecting rod 51 is provided on the connecting frame 50 along the axial direction of the take-up roller 21. A cylindrical pressure cylinder 52 located outside the take-up roller 21 is sleeved on the connecting rod 51. A gap is left between the roller surface of the take-up roller 21 and the outer wall of the pressure cylinder 52 for the aluminum strip to pass through.

[0036] The working principle of this utility model is as follows:

[0037] like Figures 1 to 2 As shown, before use, the PLC controller 4, proximity switch 33, speed sensor 34 and second linear motor 5 are all electrically connected to the battery 40.

[0038] Subsequently, as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, push the frame 1 to the corresponding output end of the aluminum strip processing equipment. Taking the cutting equipment as an example, the aluminum strip is pre-cut to the size specifications for subsequent processing. At this time, according to the cut size specifications, that is, the width of the aluminum strip after cutting, screw the clamping bolts 23 into the corresponding positions in the placement groove 22. Among them, according to the width of the aluminum strip after cutting, two clamping bolts 23 are installed symmetrically or three clamping bolts 23 are installed at the corresponding left, middle and right positions in the output direction. The lower end face of the nut of the clamping bolt 23 abuts against the upper end face of the aluminum strip end to realize the fixed connection between the aluminum strip and the winding roller 21. Since the winding roller 21 needs to rotate, the aluminum strip should be wound and bent. Since the nut clamping position is a planar abutment, in order to overcome the tensile stress formed under the influence of bending, an anti-slip boss 231 is provided on the lower end face of the nut of the clamping bolt 23. The anti-slip boss 231 is grid-shaped. The grid shape increases the resistance in multiple directions to ensure the stability of the winding and pulling.

[0039] As the aluminum strip begins to be wound, a gap is left between the roller surface of the winding roller 21 and the outer wall of the pressure cylinder 52 for the aluminum strip to pass through. The second linear motor 5 is turned on synchronously by the PLC controller 4. As the aluminum strip is wound and stacked to form an aluminum strip roll, and the thickness of the aluminum strip roll increases, the output end of the second linear motor 5 drives the connected connecting frame 50 away from the winding roller 21. That is, the pressure cylinder 52 gradually moves away from the winding roller 21, while keeping the outer wall of the pressure cylinder 52 in contact with the outer wall of the aluminum strip roll. Since there is no gap in the contact position, the aluminum strip can be effectively prevented from arching.

[0040] In the event of an emergency shutdown during production, such as Figure 1 As shown, the speed sensor 34 detects that the take-up roller 21 is not rotating and immediately sends the detection signal to the PLC controller 4. The PLC controller 4 then sends an start signal to the first linear motor 3, which drives the support block 31 to move upward and abut against the lower end face of the aluminum strip roll. Since the support block 31 is a concave arc-shaped structure, a buffer pad 32 is provided on the inner side wall of the arc-shaped structure. At the abutment position, no damage will be caused by frontal contact. Under the premise of preventing the aluminum strip roll from loosening, the outer surface of the aluminum strip is effectively protected.

[0041] Similarly, when the aluminum strip is wound to a certain diameter, that is, when the aluminum strip roll approaches the proximity switch 33 to a certain distance, the proximity switch 33 sends a signal to the PLC controller 4, which in turn sends an open signal to the first linear motor 3 and a close signal to the servo motor 20. The winding roller 21 stops rotating and the first linear motor 3 drives the support block 31 to move upward and abut against the lower end face of the aluminum strip roll, ensuring production safety. If the servo motor 20 and the production equipment are not set to open and close simultaneously, a warning light (not marked) should be electrically connected to the PLC controller 4. Once the proximity switch 33 sends a signal, the PLC controller 4 will issue a command to turn on the warning light so as to shut down the production equipment in time and avoid the aluminum strip from folding and deforming during output. In addition, the spacing between the inner wall of the support frame 10 and the maximum diameter of the aluminum strip roll should be fully considered to ensure the full winding of the aluminum strip, thereby ensuring production efficiency and safety.

[0042] In the event of a power outage, the battery 40 is connected to meet the power requirements for speed detection and lifting under power outage conditions, thereby effectively preventing the aluminum strip from becoming loose and the aluminum strip from being pulled out ineffectively.

[0043] In addition, if it is scrap material after processing coiled aluminum strip, such as Figure 1 , Figure 2 , Figure 4 and Figure 7Unlike the previous operation, this time the limiting post 24 is screwed into the placement groove 22, and the card slot 241 is twisted to face the rotation direction of the take-up roller 21. The corresponding position of the scrap material is placed into the card slot 241. At this time, the upper wall of the card slot 241 limits the scrap material (such as...) in the vertical direction. Figure 4 and Figure 7 (as shown in the diagram), so that while the take-up roller 21 rotates, the scrap aluminum strip is also dragged as a whole.

[0044] At the same time, since the gaps in the scrap are relatively large, they only need to be rolled up and sorted without being pressed again. Therefore, the outer wall of the pressure cylinder 52 does not need to be attached to the outer wall of the aluminum strip at this time.

[0045] During the above-mentioned usage, such as Figure 1 , Figure 2 and Figure 5 As shown, the foot needs to step on the lever 16 to rotate the clamp 13 downwards and make the two rubber blocks 15 clamp the end faces of the roller 11 to brake the roller 11 and prevent the frame 1 from moving. When the frame 1 needs to be moved, the foot is used to move the lever 16 to rotate the clamp 13 and make the rubber blocks 15 leave the roller 11. When the braking force is reduced to below the elastic force of the tension spring 14, the clamp 13 and the rubber blocks 15 are quickly pulled back to the initial position under the action of the elastic force of the tension spring 14, which can push the frame 1. After the frame 1 is moved into place, the position of the frame 1 can be fixed according to the corresponding content mentioned above.
