The conveying mechanism includes a pair of feed racks 2 arranged on both sides of the frame 1, and multiple conveying rollers 3 are rotatably arranged on each of the feed racks 2; a through hole is opened at one end of each fixing rod 9 away from the lead screw 8, and a pair of mounting grooves are opened on the fixing rod 9 and located on the upper and lower sides of the through hole, the mounting rod 10 passes through and is arranged in the through hole for transmission, and a plurality of conveying rollers 3 are arranged on the mounting rod 10 and located in the pair of mounting grooves. A pair of first limit blocks 11 are provided, and the pair of first limit blocks 11 protrude a certain distance from the upper and lower sides of the fixing rod 9 respectively; a handwheel 15 is provided on the top of each of the lead screws 8, and four lead screw locking members 14 are provided on the top of the frame 1 to prevent the lead screw 8 from rotating, and the lead screw 8 passes through the lead screw locking members 14; a pair of limit grooves 10-1 are provided on each of the mounting rods 10, and a second limit block 12-1 is provided on each of the correction discs 12, and the second limit block 12-1 is slidably set in the limit groove 10-1.

[0018] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] In the present invention, the first motor 6 and the second motor 7 are both connected to the external electric control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0020] According to the instruction manual Figure 1-3 It can be seen that when the present invention is in use, firstly, the lead screw 8 set in the slide groove 1-1 is screwed and rotated respectively. When the lead screw 8 rotates, the fixing rod 9 is driven to move vertically in the slide groove 1-1, and then the vertical height of each fixing rod 9 is adjusted according to the height of the H-shaped steel web, so that the fixing rod 9 can be aligned with the middle position of the web. Secondly, a correction disc 12 of appropriate diameter is selected according to the thickness of the web, and then a suitable number of correction discs 12 is selected according to the height of the web, and multiple correction discs 12 are sleeved on the installation rod 10 on both sides of the fixing rod 9. The number of correction discs 12 on both sides of the mounting rod 10 is the same. A pair of nuts 13 are screwed onto the threads of the mounting rod 10 so that the pair of nuts 13 can fix and limit the multiple correction discs 12 on the upper and lower sides of the mounting rod 10. Then, the first motor 6 and the pair of second motors 7 on the outer wall of the frame 1 are started. The output end of the first motor 6 drives the lower roller 4 to rotate, and the output end of the pair of second motors 7 drives the pair of upper rollers 5 to rotate, placing the H-shaped steel on the multiple conveying rollers 3 on the feeding frame 2 on one side, and conveying the H-shaped steel to the inside of the frame 1. When the bottom of the H-shaped steel contacts the lower roller 4, the rotating lower roller 4 can convey the H-shaped steel, and the upper roller 5 contacts the top of the lower flange plate to convey the H-shaped steel. During the conveying process, multiple groups of correction discs 12 abut against the web of the H-shaped steel to perform correction. The utility model adjusts the number of correction discs 12 on each side of the mounting rod 10 and selects the correction discs 12 with appropriate diameters, so that the correction discs 12 on both sides can correct the H-shaped steel webs of different thicknesses and heights therebetween, and has good applicability.

[0021] There is a possible implementation, in which a pair of first limit blocks 11 on each mounting rod 10 are rotatably set in a pair of mounting grooves, which can prevent the mounting rod 10 from vertically displacing on the fixed rod 9. The first limit block 11 protrudes a certain distance from the fixed rod 9. The first limit block 11 limits the correction disc 12 to prevent the correction disc 12 from abutting against the fixed rod 9, causing the correction disc 12 to be unable to rotate.

[0022] There is a possible implementation, in which a handwheel 15 is provided at the top of each screw 8, and turning the handwheel 15 facilitates operation by personnel. Four screw 8 locking members that can prevent the screw 8 from rotating are provided on the top of the frame 1, and the screw 8 passes through the screw 8 locking members. When the screw 8 is rotated to adjust the vertical height of the fixed rod 9, the screw 8 is prevented from rotating by the screw 8 locking members at the top of the frame 1. The screw 8 locking members can be MTQDB or other models.

[0023] There is a possible implementation method. A pair of limit grooves 10-1 are provided on each mounting rod 10, and a second limit block 12-1 is provided on each correction disc 12. The second limit block 12-1 is slidably set in the limit groove 10-1. The limit groove 10-1 limits the second limit block 12-1 to prevent the correction disc 12 from rotating relative to the mounting rod 10.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
