[0029] The bending unit comprises a support plate 501 fixedly connected to the front end of the upper side of the workbench 1, a rectangular frame 502 fixedly connected to the upper side of the support plate 501 at equal distances, a sliding plate 503 slidingly connected to the inner side of the rectangular frame 502, a first bearing 504 fixedly connected to the middle position of the inner upper end of the sliding plate 503, a first threaded rod 505 fixedly connected to the inner side of the first bearing 504, a first handle 506 welded to the upper end of the first threaded rod 505, a motor 507 installed on the front side of the sliding plate 503, a transmission roller 508 fixedly connected to the rear end of the output shaft of the motor 507, a rectangular slot formed in the front end of the inner side of the workbench 1 at equal distances, a first circular shaft 3 fixed to the inner side of the rectangular slot, and conveying rollers 4 slidingly connected to the front and rear sides of the rectangular slot, wherein the outer ends of the transmission roller 508 and the conveying rollers 4 are rollingly connected to the upper and lower sides of the aluminum strip to be conveyed, so that the output shaft of the motor 507 is rotated to drive the transmission roller 508 above the aluminum strip to rotate, and the aluminum strip between the conveying rollers 4 and the transmission roller 508 can be moved to the right end.

[0030] A first threaded hole is formed in the middle position of the inner upper end of the rectangular frame 502, and the outer side of the first threaded rod 505 is threadedly connected to the inner side of the first threaded hole, so that when the first threaded rod 505 is rotated in the first threaded hole by rotating the first handle 506, the sliding plate 503 can be driven to slide along the inner side of the rectangular frame 502, so that the height position of the transmission roller 508 is changed, and the spacing between the conveying rollers 4 and the transmission roller 508 is changed, thereby facilitating the conveying of aluminum strips of different thicknesses.

[0031] A support table 509 is fixedly connected to the right rear end of the workbench 1, a cylinder 510 is installed on the upper end of the support table 509, a connecting frame 511 is fixedly connected to the front end of the inner side of the cylinder 510, a second circular shaft 512 is fixedly connected to the inner side of the front end of the connecting frame 511, a bending roller 513 is rotatably connected to the outer end of the second circular shaft 512, a circular roller 514 is fixedly connected to the right front end of the workbench 1, and the outer end of the bending roller 513 is rollingly connected to the outer end of the aluminum strip to be bent, so that after the aluminum strip is conveyed to the bending position at the right end of the workbench 1, the output shaft of the cylinder 510 is extended to drive the bending roller 513 to move forward and contact the aluminum strip, and then the aluminum strip is bent around the circular roller 514 during the subsequent forward movement, and the bending roller 513 rolls on the outer side of the aluminum strip, so that the bending roller 513 does not slide along the outer side of the aluminum strip to generate friction and wear, and the outer side of the aluminum strip is protected.

[0032] The limiting unit includes a fixed plate 601 fixedly connected to the upper rear end of the worktable 1. Limiting rods 602 are fixedly connected to the left and right ends of the front side of the fixed plate 601. A push plate 603 is connected between the limiting rods 602. Limiting grooves are opened on the adjacent side of the two limiting rods 602 at the left and right ends of the front side of the fixed plate 601. The outer sides of the left and right ends of the push plate 603 are slidably connected to the inner side of the limiting groove. Thus, when the push plate 603 moves, its left and right ends can only slide along the inner side of the limiting groove, thereby limiting the movement of the push plate 603.

[0033] A second bearing 604 is fixedly connected to the middle of the rear end of the push plate 603. A second threaded rod 605 is fixedly connected to the inner side of the second bearing 604.

The outer side of the second threaded rod 605 is threadedly connected to the inner side of the second threaded hole. When the second handle 606 is rotated and the second threaded rod 605 is rotated in the second threaded hole, the push plate 603 can be driven to slide along the inner side of the limiting groove. At the same time, the distance between the support plate 501 and the push plate 603 changes, so as to transport aluminum strips of different widths to the right-hand bending position while keeping them horizontal between the support plate 501 and the push plate 603.

[0034] Working principle: When bending the aluminum strip of insulating glass, the motor 507 is started first, and its output shaft rotates to drive the transmission roller 508. The aluminum strip to be bent is then placed between the support plate 501 and the push plate 603 from the left end. When the aluminum strip moves between the transmission roller 508 and the conveying roller 4, it is driven by the rotating transmission roller 508 to move to the right along the support plate 501 and the push plate 603 until it reaches the bending position at the right end of the worktable 1. The motor 507 is then turned off, and the cylinder 510 is turned on. Its output shaft extends to drive the bending roller 513 to move forward and contact the aluminum strip. During the forward movement, the aluminum strip is pushed to bend around the circular roller 514. At the same time, the bending roller 513 rolls outside the aluminum strip until the aluminum strip is bent to the required angle. The bending roller 513 is then reset, the motor 507 is turned on again, and the aluminum strip at the left end is conveyed to the right. At the same time, the aluminum strip that has been bent at the right end is pushed down from the right end and collected.
