[0041] The scissor-type assembly includes a fixing block 6 fixed to the bottom of the most central mounting plate 2, pulleys 7 are fixed to the bottom of the mounting plates 2 symmetrically located on both sides of the fixing block 6, and scissor-type structures 8 are rotatably connected to the bottom of several mounting plates 2.

[0042] This application sets up an adjustment component so that the floor space of the feeding device can be adjusted within a certain range according to needs, which is suitable for more processing plants. It only needs to drag a mounting plate 2 at one end to make the pulley 7 roll to drive other transport roller components to move equidistantly. The operation is simple and practical.

[0043] Figures 1 to 5 A second embodiment is shown, and its main difference from the first embodiment is that the cleaning component includes a slide rail 9 fixed to the side of the mounting plate 2 away from the limiting rod 4, a slide sleeve 10 is slidably connected to the outer wall of the slide rail 9, a cleaning brush 11 is fixed to the end of the top of the slide sleeve 10 away from the straightening assembly 1, a first motor 12 is symmetrically fixed to the top of the slide sleeve 10, a rubber wheel 13 is fixed to the output end of the first motor 12, and the rubber wheel 13 is slidably connected to the top of the mounting plate 2.

[0044] The transport roller assembly includes a telescopic sleeve 14 symmetrically fixed to the top of the mounting plate 2, a fixing frame 15 is fixed to the top of the telescopic sleeve 14, the inner wall of the fixing frame 15 is rotatably connected to a transport roller 16 through a bearing, an anti-slip groove 19 is provided on the outer wall of the transport roller 16, a second motor 17 is fixed to the end of the fixing frame 15 away from the limiting rod 4, the output end of the second motor 17 passes through the fixing frame 15 and is fixed to one end of the transport roller 16, a hydraulic rod 18 is fixed to the top of the mounting plate 2, and the output end of the hydraulic rod 18 is fixed to the bottom of the fixing frame 15.

[0045] During the process of transporting the steel pipe using the feeding device, rust and dust may remain on the transport roller 16, resulting in reduced friction between the steel pipe and the transport roller 16 and thus reduced transport efficiency. This application solves this problem by providing a cleaning component to automatically clean the rust and dust.

[0046] This application provides power on each transport roller assembly so that the number of transport roller assemblies in operation can be selected according to the length of the steel pipe, without having to start all of them to consume excess electricity, which is economically beneficial.

[0047] Working principle:

[0048] The steel pipe is put in from the open end of the limiting rod 4, and several transport roller assemblies are selectively opened according to the length of the steel pipe; after the steel pipe enters the transport roller 16, the hydraulic rod 18 rises to lift the transport roller 16 on the fixed frame 15, and the telescopic sleeve 14 extends accordingly, thereby lifting the transport roller 16, so that the steel pipe is limited by the limiting rod 4, and the second motor 17 is started to drive the transport roller 16 to rotate and transport the steel pipe into the straightening assembly 1 for straightening the steel pipe.

[0049] The floor area of ​​the feeding device can be adjusted within a certain range according to the size of the processing plant; one of the mounting plates 2 at one end is moved to make the pulley 7 below roll, and under the action of the scissor structure 8, the mounting plates 2 on both sides of the fixed block 6 are moved equidistantly, and at the same time, the slide bar 5 slides in the slide hole 3, thereby adjusting the spacing between several transport roller assemblies, thereby completing the adjustment of the floor area of ​​the feeding device.

[0050] Starting the first motor 12 can drive the rubber wheel 13 to roll on the top of the mounting plate 2, and the sleeve 10 slides on the outer wall of the slide rail 9. At the same time, the second motor 17 drives the transport roller 16 to rotate, so that the cleaning brush 11 moves toward the direction close to the straightening component 1 to clean the dust and rust on the surface of the transport roller 16; when the sleeve 10 moves between the two mounting plates 2, one of the rubber wheels 13 first leaves the previous mounting plate 2 and reaches the next mounting plate 2, and then the other rubber wheel 13 leaves the previous mounting plate 2. During the movement, there is always a rubber wheel 13 on one mounting plate 2 to ensure that the sleeve 10 can smoothly dock with the slide rail 9; after cleaning, the cleaning brush 11 returns to the mounting plate 2 away from the end of the straightening component 1.
