The arrangement of at least two groups of the upper rollers 2 and the lower rollers 3 can ensure that the workpiece is straightened. By setting the upper roller mounting assembly 4 to press the upper rollers 2 and the lower rollers 3, the friction force can be enhanced by increasing the pressure, so that the conveying process of the workpiece is not easy to slip, and the operation is more stable. Since the lower rollers 3 are drivingly connected with each other, the motor 8 only needs to be drivingly connected with one of the lower rollers 3 to transmit power to each of the lower rollers 3. Preferably, as an embodiment, the upper rollers 2 are provided with 7. The size of each of the upper rollers 2 should be the same, and they are aligned along a straight line in the radial direction, and the lower rollers 3 are arranged in the same way. Because the present application not only plays a conveying role, but also needs to play a role in flattening and straightening the workpiece, the arrangement of multiple groups of the upper rollers 2 and the lower rollers 3 can better flatten and straighten the workpiece, and reduce the machining error that may be caused by the uneven workpiece in the subsequent process.

Preferably, as an embodiment, the spring mounting column 4.2 is arranged at both sides of the upper roller 2, so as to keep the upper roller 2 balanced.

[0026] Preferably, the upper roller mounting assembly 4 further comprises a limiting bolt 4.5 connected with the fixed frame 1 and inserted into the mounting base 4.1, and a high-limiting nut 4.6 and a low-limiting nut 4.7 arranged at both ends of the limiting bolt 4.5; the movement range of the mounting base 4.1, and the movement range of the upper roller 2, can be adjusted by cooperation of the high-limiting nut 4.6 and the low-limiting nut 4.7; the upper roller 2 and the lower roller 3 can keep an initial opening distance by adjusting the position of the low-limiting nut 4.7, so as to facilitate the end of the workpiece to extend in. Preferably, as an embodiment, the limiting bolt 4.5 is arranged at both ends of the upper roller 3.2, so as to keep the upper roller 2 balanced.

[0027] Preferably, the upper roller mounting assembly 4 further comprises a guide shaft 4.8 connected with the fixed frame 1 and inserted into the mounting seat 4.1; preferably, as an embodiment, the guide shaft 4.8 should be selected as a light shaft, although the spring mounting column 4.2 and the limiting bolt 4.5 also have certain positioning and guiding functions, their surfaces are not smooth enough or are not suitable for applying lubricating oil, which will affect the smoothness when sliding; the special guide shaft 4.8 is configured to facilitate the mounting seat 4.1 to slide up and down smoothly along the guide shaft 4.8; and due to the positioning effect of the guide shaft 4.8, the mounting seat 4.1 is not easy to shake, thereby preventing the upper roller 2 from shaking during work and preventing its working stability from being affected. Preferably, as an embodiment, one is arranged at each end of the upper roller 3.2 to maintain the balance of the upper roller 2.

[0028] Preferably, a first bearing 2.1 is arranged between the upper roller 2 and the mounting seat 4.1; thereby realizing the rotary connection of the upper roller 2 and the mounting seat 4.1 and improving the stability thereof during work.

[0029] Preferably, the lower roller 3 is symmetrically provided with a matching shaft 3.2 on the two end faces, and a second bearing 3.1 is arranged on the matching shaft 3.2 and rotatably connected with the fixed frame 1; this design enables the lower roller 3 to rotate relative to the fixed frame 1, and the symmetric arrangement of the matching shaft 3.2 on the two end faces of the lower roller 3 facilitates the balance of the two sides of the lower roller 3, thereby improving the stability thereof during work.

[0030] Preferably, the first transmission chain 5 is arranged between the adjacent lower rollers 3 and transmissionally connects the two lower rollers 3, and the first transmission chain 5 is matched with the toothed disc 3.3 arranged on the matching shaft 3.2; the transmission chain has a simple structure and stable transmission, and the use of this transmission mode can ensure the stability of the conveying speed; at the same time, after the transmission chain is lubricated, the frictional resistance when the first transmission chain 5 contacts with the toothed disc 3.3 will be effectively reduced, and smooth operation can be maintained even under high speed or high load state, power fluctuation is reduced, and the stability of the rotating speed is further ensured, thereby ensuring the stability of the workpiece conveying.

[0031] Preferably, the power output end of the motor 8 is transmissionally connected with one of the lower rollers 3 through the second transmission chain 6; as above, the transmission chain has stable transmission, and the rotation of the motor 8 can be accurately transmitted to the lower roller 3, thereby enabling the conveying speed of the utility model to be more accurately controlled by controlling the rotating speed of the motor 8 during operation.

[0032] Preferably, the curved surface of the upper roller 2 and the lower roller 3 is provided with a working surface 7 in the shape of an arc around the circumference thereof; when the lowest point of a flat surface is a line, the workpiece can slide on the surface; the lowest point of the arc surface is a point, which forces the workpiece to slide into a fixed position in the working surface 7, which helps to fix the workpiece along a straight line, thereby better flattening and straightening the workpiece.

[0033] The use method of the utility model is: when setting, the curved surfaces of the upper roller 2 and the lower roller 3 should be aligned, then the workpiece is clamped between the two; the friction force of the lower roller 3 during rotation converts its rotary motion into linear motion of the workpiece, so that the workpiece can be conveyed; the upper roller 2 does not rotate itself, but is pressed on the workpiece and the lower roller 3 by the elastic force of the spring 4.3, so that the friction between the workpiece and the lower roller 3 is stronger, and the transmission of the lower roller 3 to the workpiece is more stable; then the upper roller 2 converts the linear motion of the workpiece into its rotary motion, preventing the workpiece from being conveyed due to its own friction.

[0034] The size of each upper roller 2 should be the same, and they are aligned along a straight line in the radial direction; the lower rollers 3 are also set in the same way; because the utility model not only plays a conveying role but also needs to play a role in flattening the workpiece, setting multiple sets of upper rollers 2 and lower rollers 3 can better flatten the workpiece, thereby reducing the processing errors that may occur in subsequent processes due to the unevenness of the workpiece.

[0035] The power source of the lower roller 3 is the motor 8; using the second transmission chain 6 to connect the outermost lower roller 3 and the motor 8 ensures that the power output by the motor 8 can be stably transmitted to the lower roller 3; similarly, using the first transmission chain 5 to connect each lower roller 3 can make the power transmitted between the lower rollers 3 stably, thereby ensuring the stability of the conveying speed of the utility model when conveying the workpiece, thereby reducing the processing errors that may occur in the subsequent cutting process.

[0036] By aligning the upper roller 2 and the lower roller 3, the workpiece can be clamped between the two and fixed by friction, then conveyed by the rotation of the lower roller 3, and flattened at the same time; setting at least two sets of upper rollers 2 and lower rollers 3 can ensure that the workpiece is straightened; by setting the upper roller mounting assembly 4 to press the upper roller 2 and the lower roller 3, the friction force can be enhanced by increasing the pressure, thereby making the conveying process of the workpiece not easy to slip and running more stably. Since the lower rollers 3 are connected to each other, the motor 8 only needs to be connected to one lower roller 3 to transmit power to each lower roller 3.

[0037] The utility model discloses the advantage lies in: through the alignment of the upper roller and lower roller, workpiece can be set up between two and fixed with the help of friction force, then with the rotation of lower roller is transported, and in the same time flattening workpiece, set up at least two groups the upper roller and lower roller can ensure that workpiece is straightened, through the setting up upper roller mounting subassembly to the upper roller and lower roller can be compact, can enhance friction by enhancing pressure, thereby the conveying process of workpiece is not easy to slip, and operation is more stable.

[0038] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the utility model, but not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
