[0024] REFERENCE Figures 1 to 4 The present application provides a friction type flattening roller, which comprises a supporting shaft 30 and a flattening assembly arranged on the supporting shaft 30, wherein the flattening assembly comprises a first flattening assembly 301 and a second flattening assembly 302, and the first flattening assembly 301 and the second flattening assembly 302 are arranged transversely on the supporting shaft 30.

[0025] The second flattening assembly 302 comprises a cylindrical cam 36 fixedly arranged on the supporting shaft 30, wherein the cylindrical cam 36 is provided with an annular guide groove 360, and the guide groove 360 has a protrusion 362 directed away from the center of the supporting shaft. The structural difference between the first flattening assembly 301 and the second flattening assembly 302 is only in the design of the guide groove, specifically, the protrusion of the guide groove 360 of the first flattening assembly 302 is directed to one side away from the center of the supporting shaft 30, and the protrusion of the guide groove of the second flattening assembly 302 is directed to the other side away from the center of the supporting shaft 30.

[0026] The second flattening assembly 302 further comprises a bearing 352 arranged on the supporting shaft 30, wherein the bearing 352 is arranged on both sides of the cylindrical cam 36, and both sides of the bearing 352 are provided with a chuck 351, which can fix the position of the bearing 352 to prevent it from deviating. The outer periphery of the bearing 352 is provided with a rotary support 35, and the rotary support 35 is provided with a plurality of first mounting seats 33, and the first mounting seat is provided with a first mounting hole (not shown in the figure).

[0027] The second flattening assembly further comprises a plurality of arc-shaped friction plates 31, and the inner periphery of the friction plate 31 is provided with a second mounting seat 32, and the second mounting seat 32 is provided with a second mounting hole (not shown in the figure).

[0028] The second flattening assembly further comprises a guide shaft 34, which penetrates the first mounting hole and the second mounting hole, so that the friction sheet 31 is connected with the swivel bracket 35, and the outer periphery of the plurality of friction sheets 31 can be enclosed to form a cylindrical roller surface.

[0029] The guide shaft 34 is further connected with a guide block 361, which is arranged in the guide groove 360 and can slide along the guide groove 360.

[0030] When the outer periphery of the friction sheet 31 feels a friction force, it will rotate with the friction force, driving the guide shaft 34 to rotate, which will drive the guide block 361 to slide along the guide groove 360. When the guide block 361 moves to the protruding position in the guide groove 360, the friction sheet 31 will move towards the protruding direction, and due to the special design of the annular guide groove, the friction sheet 31 can also move back to the initial position under the guidance of the guide groove 360. In actual application, the axial positions of the first flattening assembly and the second flattening assembly on the support shaft can be adjusted to adapt to different widths of the foil.

[0031] Referring to Figure 5 , the present application also provides a flattening mechanism, which comprises the friction flattening roller 3 described above, and further comprises a support 1 and a support roller 2, which is arranged in parallel with the support shaft 30 in the longitudinal direction and is connected to the support 1 at both ends, and the outer periphery of the friction sheet 31 and the roller surface of the support roller 2 have a gap for the belt material to pass through, and the protrusion of the guide groove is located near the belt material.

[0032] Both ends of the support shaft 30 are connected to the support 1 through a sliding platform 5, which comprises a mounting plate 50, a sliding shaft 52, and a sliding block 51 arranged on the sliding shaft, both ends of the sliding shaft 52 are connected with a mounting block 501, the mounting block 501 is connected to the mounting plate 50, the sliding block 51 can slide along the sliding shaft 52, and the mounting plate 50 is provided with a scale 54, through which the vertical height of the sliding block 51 can be determined, facilitating the height adjustment of the operator.

[0033] The sliding block 51 and the support shaft 30 are connected through a connecting block 53, and the height of the support shaft 30 can be adjusted by adjusting the vertical height of the sliding block 51 connected to both ends of the support shaft 30, further realizing the adjustment of the gap between the outer periphery of the friction sheet 31 and the support roller 2.

[0034] The working principle is that the two ends of the supporting roller 2 can be connected with a driving device, the driving device controls the rotation of the supporting roller 2, when the strip transmission work is carried out, the friction force is generated between the roller surface of the supporting roller 2 and the strip, the transportation of the strip is realized through the friction force. Since the strip passes through the gap between the supporting roller 2 and the outer circumferential surface of the friction sheet 31, the strip can provide the rotating friction force to the outer circumferential surface of the friction sheet 31 during the transportation, so as to drive the guide shaft 34 and the guide block 361 to slide along the guide groove 360, the friction sheet 31 moves to the protruding direction, the flattening force from the center to the outside is applied to the strip, the flattening effect is realized. Repeating the action, the continuous flattening force is applied to the strip, at the same time, as long as the guide grooves of the two flattening assemblies are symmetrical and the roughness of the surface of the friction sheet 31 is close, the flattening forces in the width direction of the strip which are opposite in direction and close in size can be applied, the deviation of the strip caused by the inconsistent flattening forces on both sides of the strip is avoided.

[0035] By using the flattening mechanism, the flattening effect of the strip can be realized, and the deviation of the strip during the transportation is avoided.

[0036] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the above-mentioned embodiments, those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
