Description

Technical Field

[0001] The invention relates to the technical field of conveying and turning over slender materials used in a high-frequency welded pipe production line, and in particular to a material conveying and turning roller. Background Art

[0002] In the field of modern, fully automated, and efficient production lines, situations often arise where the conveying direction of slender materials on conveyor rollers needs to be changed, or the conveyor rollers themselves need to be changed. The conventional method for changing the conveyor rollers or conveying direction of slender materials is to use a flip roller system, where two sets of conveyor rollers are arranged horizontally and symmetrically and can rotate around a single axis. However, this structural method occupies a large rotational space in actual applications, and the slender materials are thrown upward when flipped out of the original roller, causing significant collisions when entering the next roller, which can damage the outer surface of the slender materials. Alternatively, a lever can be used to move the slender materials off the original roller and onto another roller. This method is slightly more complex in structure and also takes up a large amount of space. Therefore, to solve this problem, the design of a space-saving, simple, and convenient feed flip roller has become an inevitable trend. Summary of the Invention

[0028] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified, “perpendicular” and “parallel” do not just have absolute meanings in a mathematical sense, but can be understood as “approximately perpendicular” and “approximately parallel”.

[0029] Figure 1 It is a schematic diagram of the basic structure of the overall layout of the first embodiment of the present invention.

[0030] Figure 5 It is a schematic diagram of the internal structure of the first embodiment of the present invention.

[0031] like Figure 1 and Figure 5As shown, this embodiment provides a space-saving and structurally simple and convenient material conveying roller. By providing a turning axis and distributing multiple guide rollers radially along the turning axis, each with its axis perpendicular to the turning axis and intersecting at a point, the guide rollers are combined to form a guide trough for conveying material. This technical solution is structurally simple and space-saving. In a specific embodiment, this technical solution may include a guide roller set d and a turning axis f. In this embodiment, the turning axis f is configured as a centrally located triangular-shaped rotation axis fz, with the centerline of the triangular shape coinciding with the centerline of the rotation axis fz. The triangular shape is an equilateral triangle, and the diameter of its inscribed circle is greater than the maximum diameter of the rotation axis fz. The side plane of the triangular shape is provided with a first roller fg1, a second roller fg2 and a third roller fg3 uniformly distributed around the center line of the rotation axis fz, and the axis centers of the first roller fg1, the second roller fg2 and the third roller fg3 are perpendicular to the axis center line of the flip axis f and intersect with each other at a point on the axis center line of the flip axis f, and the angles between the axis centers of the first roller fg1, the second roller fg2 and the third roller fg3 are all 120 degrees.

[0032] According to one aspect of a specific implementation of the first embodiment of the present invention, the guide roller group d further includes a first guide roller d1, a second guide roller d2, and a third guide roller d3, each having the same conical shape. The first guide roller d1 is provided with a first guide bottom surface d1d and a first guide side surface d1c that intersect with each other, the second guide roller d2 is provided with a second guide bottom surface d2d and a second guide side surface d2c that intersect with each other, and the third guide roller d3 is provided with a third guide bottom surface d3d and a third guide side surface d3c that intersect with each other. The first guide roller d1 is rotatably mounted on a first roller shaft fg1, the second guide roller d2 is rotatably mounted on a second roller shaft fg2, and the third guide roller d3 is rotatably mounted on a third roller shaft fg3. Rotating the turning axis f can cause the first guide roller d1, the second guide roller d2, and the third guide roller d3 to turn.

[0033] The first guide bottom surface d1d and the first guide side surface d1c, along with the second guide bottom surface d2d and the second guide side surface d2c, form a first guide groove on adjacent sides. The first guide bottom surface d1d and the second guide bottom surface d2d form the bottom of the first guide groove, and the first guide side surface d1c and the second guide side surface d2c form two sides of the first guide groove. The second guide bottom surface d2d and the second guide side surface d2c, along with the third guide bottom surface d3d and the third guide side surface d3c, form a second guide groove on adjacent sides. The second guide bottom surface d2d and the third guide bottom surface d3d form the bottom of the second guide groove, and the second guide side surface d2c and the third guide side surface d3c form two sides of the second guide groove. The third guide bottom surface d3d and third guide side surface d3c, along with the first guide bottom surface d1d and first guide side surface d1c, form a third guide groove on adjacent sides. The third guide bottom surface d3d and the first guide bottom surface d1d form the bottom of the third guide groove, while the third guide side surface d3c and the first guide side surface d1c form the sides of the third guide groove. When the turning axis f is rotated clockwise, the first, third, and second guide grooves alternate at the upper end of the guide roller assembly d. When the turning axis f is rotated counterclockwise, the first, second, and third guide grooves alternate at the upper end of the guide roller assembly d.

[0035] Figure 3 It is a schematic diagram of the flipping action of the first embodiment of the present invention.

[0036] Figure 4 It is a schematic diagram of the discharge of the slender material w according to the first embodiment of the present invention.

[0037] like Figure 2 、 Figure 3 and Figure 4 As shown, according to one aspect of the first embodiment of the present invention, multiple conveyor rollers can be arranged side by side along the axis of their rotational axis fz, and these multiple conveyor rollers can operate synchronously. A material receiving plate j can also be positioned to the side of each conveyor roller for receiving the material. The specific workflow is as follows: the production line first conveys an elongated material w to the first, upward-facing guide groove of the guide roller assembly d. Once the elongated material w is completely positioned above the first guide groove, the rotational axis fz is rotated clockwise, causing the guide roller assembly d to rotate synchronously, causing the elongated material w to slide rightward onto the material receiving plate j under the combined force of the guide roller assembly d's push and its own weight. Gradually, the elongated material w completely disengages from the guide roller assembly d. At this point, the guide roller assembly d continues to rotate, causing the third guide groove to face upward, completing a single work cycle.

The side plane of the square shape is provided with a first roller fg1, a second roller fg2, a third roller fg3, and a fourth roller fg4, which are uniformly distributed around the centerline of the rotation axis fz. The axis lines of the first roller fg1, the second roller fg2, the third roller fg3, and the fourth roller fg4 are all perpendicular to the axis line of the flip axis f and intersect at a point on the axis line of the flip axis f. The axis lines of the first roller fg1, the second roller fg2, the third roller fg3, and the fourth roller fg4 are all at 90 degrees relative to each other.

The second guide bottom surface d2d and the third guide bottom surface d3d form the bottom of the second guide groove, and the second guide side surface d2c and the third guide side surface d3c form two sides of the second guide groove.

[0046] like Figure 7 、 Figure 8 and Figure 9As shown, according to one aspect of a second embodiment of the present invention, multiple conveyor rollers can be arranged side by side along the axis of their rotating shafts fz, and these rollers can operate synchronously. A material receiving plate j can also be positioned to the side of each conveyor roller for receiving the material.

Once the elongated material w is completely positioned above the first guide groove, the rotating shaft fz is rotated clockwise, causing the guide roller assembly d to rotate synchronously, causing the elongated material w to slide rightward onto the material receiving plate j under the combined force of the guide roller assembly d's push and its own weight. Gradually, the elongated material w completely disengages from the guide roller assembly d. At this point, the guide roller assembly d continues to rotate, causing the fourth guide groove to face upward, completing a single work cycle.
