Through the mutual cooperation of the lifting mechanism, the bracket conveying mechanism and the adjustment mechanism, a feeding device for steel structure processing is realized, so that the steel structure feeding device can adjust the use length and use height.

[0004] One shortcoming of this device is that a new conveyor belt needs to be replaced after adjusting the length, which lacks some convenience in use. In addition, the length of fixed-specification conveyor belts is fixed, so the length adjustment of this device will be limited by the specifications of the conveyor belt and cannot be arbitrarily adjusted within a certain range.

[0020] The device realizes the feeding and transmission of steel structure components by setting a driving roller 13, a driven roller 6, a transmission belt 7 and a supporting mechanism. A pair of movable pillars are moved horizontally by setting a length adjustment mechanism, thereby changing the distance between the driven roller 6 and the driving roller 13, thereby realizing the adjustment of the transmission length. At the same time, when the device is adjusting the length, the gravity tensioning mechanism can keep the transmission belt 7 in a tensioned state, and the supporting mechanism can carry the steel structure components together with the transmission belt 7, thereby improving the stability of the steel structure components during transmission.

[0022] Furthermore, a counterweight block 21 is installed on the upper portion of the mounting plate 18;

[0023] Under the action of gravity of the mounting plate 18 and the mounting block 21, a plurality of first tension rollers exert downward pressure on the conveyor belt 7, so that the conveyor belt 7 remains in a tensioned state. When the distance between the driving roller 13 and the driven roller changes, the sliding column 19 at the bottom of the mounting frame 18 slides on the inner wall of the sleeve 20, so that the plurality of first tension rollers 17 move up and down to match the change in the transmission length of the device.

[0024] Further, the length adjustment mechanism includes a sliding beam 4, the sliding beam 4 is slidably connected to the base 1 through a slide rail 2, the lower end of the movable support 5 is not fixedly connected to the sliding beam 4, a threaded rod 3 is rotatably mounted on the base 1, the threaded rod 3 is threadedly connected to the sliding beam 4, and one end of the threaded rod 3 is connected to a crank 11;

[0025] The threaded rod 3 is rotated by shaking the crank 11 , thereby causing the sliding beam 4 together with the movable support 5 to move horizontally on the slide rail 2 , thereby changing the distance between the driven roller 6 and the driving roller 13 .

[0026] Furthermore, a mounting frame 15 is provided on the base 1, and a plurality of pairs of second belt tension rollers 16 are rotatably mounted on the mounting frame 15, and a pair of the second belt tension rollers 16 are symmetrically arranged on both sides above the first belt tension roller 17, and the second belt tension rollers 16 are in contact with the lower outer surface of the conveyor belt 7;

[0027] By setting a pair of second tension rollers 16 and a first tension roller 17, each first tension roller 17 is wrapped by the transmission belt 7. At the same time, there are multiple first tension rollers 17. Therefore, when adjusting the transmission length of the device, the distance that the mounting plate 18 moves up and down is much smaller than the horizontal movement distance of the movable support 5. At the same time, the setting of the second tension roller 16 can maintain a larger wrap angle between the transmission belt 7 and the active roller 13 to ensure the stability of the transmission.

[0028] Further, the support mechanism includes a first side beam 8 fixedly mounted on the movable support 5, a second side beam 12 is connected to the fixed support 14, a sliding rod 10 is connected to one end of the first side beam 8 close to the second side beam 12, the sliding rod 10 is slidably connected to the second side beam 12, and a plurality of load-bearing rollers 9 are rotatably mounted on the upper part of the second side beam 12 and the first side beam 8, and the plurality of load-bearing rollers 9 are in contact with the upper inner surface of the conveyor belt 7;

[0029] A plurality of load-bearing rollers 9 support the upper portion of the conveyor belt 7 , and the slide bar 10 can slide on the second side beam 12 when adjusting the transmission length of the device.

[0030] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0031] Embodiment: By setting a driving roller 13, a driven roller 6, a transmission belt 7 and a supporting mechanism, the driving mechanism is used to rotate the driving roller 13 and then move the transmission belt 7 to realize the transmission of the steel structure component. When the transmission length of the device needs to be adjusted, the handle 11 is shaken to rotate the threaded rod 3, so that the sliding beam 4 together with the movable support 5 moves horizontally on the slide rail 2, thereby changing the distance between the driven roller 6 and the driving roller 13. A plurality of first tensioning rollers apply downward pressure to the transmission belt 7 under the action of the gravity of the mounting plate 18 and the mounting fastener 21, so that the transmission belt 7 is kept in a taut state. When the distance between the driving roller 13 and the driven roller changes, the mounting fastener 21 is used to adjust the transmission length of the device. The sliding column 19 at the lower part of the frame 18 slides on the inner wall of the sleeve 20, so that several first tension rollers 17 move up and down to cooperate with the change of the transmission length of the device. At the same time, by setting a pair of second tension rollers 16 to cooperate with a first tension roller 17, each first tension roller 17 is wrapped by the transmission belt 7. At the same time, the number of first tension rollers 17 is multiple, so when adjusting the transmission length of the device, the distance that the mounting plate 18 moves up and down is much smaller than the horizontal movement distance of the movable support 5. Several load-bearing rollers 9 support the upper part of the transmission belt 7. When adjusting the transmission length of the device, the sliding rod 10 can slide on the second side beam 12.
