[0039] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0040] For example, when describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional view showing the device structure will not be partially enlarged according to the general scale, and the schematic view is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional space dimensions of length, width and depth should be included.

[0041] For ease of description, spatial relational terms such as "under", "below", "below", "below", "above", "on", etc. may be used herein to describe the relationship of one element or feature shown in the drawings to other elements or features. It will be understood that these spatial relational terms are intended to include other directions of the device in use or operation in addition to the directions depicted in the drawings. In addition, when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or there can be one or more intervening layers. As used herein, "between..." means including the end point values.

[0042] In the context of the present application, a structure in which a first feature is described as being "above" a second feature may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact.

[0043] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and therefore the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0044] like Figure 1-Figure 7 As shown, the present invention provides an automatic alignment and feeding device for steel sections, the alignment and feeding device comprising at least two frames 2 arranged in the width direction; each of the frames 2 is fixed with an alignment slider 16 at the same position on its upper surface, and a chain 15 is arranged in a through groove of each of the frames 2 along the length direction and can be rotated under the action of a driving force;

[0045] A plurality of gear rows 1 are fixedly connected to the chain 15, and the gear rows 1 of each of the frames 2 move synchronously. The gear row 1 that moves to the top of the frame 2 moves forward with the chain 15, and the steel sections are placed across at least two of the frames. When the steel sections move forward under the action of the chain, the alignment slider 16 can block the moving steel sections. After the steel sections blocked by the alignment slider 16 contact the gear row 1, they pass over the alignment slider 16 under the push of the gear row 1. Finally, under the push of the gear rows 1 of each frame 2, the steel sections are corrected to be perpendicular to the length direction, and at the same time, each steel section contacts the long side of the gear row 1 to achieve alignment.

[0046] Specifically, the sizes and settings of the alignment slider 16, chain 15, gear row 1 and other components in each of the frames 2 are the same to achieve synchronous movement, thereby correcting the steel. The figure only shows the structure of one frame, and the number of frames 2 can be adjusted according to the length of the steel, for example, it can be 3, 5 or 8, and there is no excessive restriction here. The steel just placed on the frame may be skewed. The steel moves forward under the friction of the chain or the push of the gear row 1, and is blocked after hitting the alignment slider 16. After the moving steel contacts the gear row 1, the steel is pushed by the gear row 1 to pass over the alignment slider 16. Finally, under the push of the gear row 1 of each frame 2, the skewed steel is uniformly corrected to be perpendicular to the length direction, and at the same time, each steel is aligned with the long side of the gear row 1. Through the joint action of the gear rows 1 of multiple frames 2, the long side of the steel is aligned, so that the steel is neatly loaded, which is convenient for subsequent automatic grinding operations.

[0047] Furthermore, if Figure 1 As shown, the side of the alignment slider 16 contacting the steel section is an inclined surface, so as to block the moving steel section and enable the steel section to pass under the push of the gear row 1. As a preferred solution, the longitudinal section of the alignment slider 16 along the length direction is a trapezoid.

[0048] Furthermore, if Figure 2 As shown, the alignment slider 16 is arranged on the upper surface of the frame near one end of the driven shaft, and the alignment sliders are symmetrically arranged on both sides of the chain 15. Specifically, the number of the alignment sliders is not limited to one, and can also be two, as long as the position is symmetrical, so as to have a synchronous blocking effect on the steel section. Of course, for the chain 15 and the alignment slider 16, it can also be arranged in a way that the chain is on the left and the alignment slider is on the right. The alignment slider 16 can also be set at one end close to the transmission shaft. In this case, the movement direction of the gear row 1 needs to be adjusted to move from front to back. As long as the relative movement direction is kept unchanged, it can play a blocking and pushing role on the steel section.

[0049] Furthermore, if Figure 3-Figure 4 As shown, a transmission shaft 5 is provided at one end of the frame 2, and a driven shaft 9 is provided at the other end. The transmission sprocket 7 is coaxially fixed with the transmission shaft 5, and the driven sprocket 10 is coaxially fixed with the driven shaft 9. The transmission sprocket 7 and the driven sprocket 10 are connected through the chain 15 to realize the rotation of the chain 15 under the driving force of the transmission shaft 5;

[0050] Furthermore, the driven shaft 9 passes through a square seat bearing 11 to achieve a fixed connection with the frame 2 .

[0051] Furthermore, the transmission shaft 5 passes through a slider seat bearing 8 , and the slider seat bearing 8 is placed on a guide rail 6 , so that it can move along the length direction of the frame 2 to adjust the tension of the chain 15 .

[0052] Furthermore, if Figure 5 As shown, the frame 2 is provided with a flange plate, and the screw rod 4 passes through the flange plate 12 along the length direction of the frame 2 and abuts against the slider seat bearing 8. By adjusting the extension length of the screw rod 4, the slider seat bearing 8 can be moved forward and backward on the guide rail 6, thereby adjusting the entire length of the chain 15 and its tension. The flange plate 12 is fixed to one end of the guide rail 6, and the other end of the guide rail 6 is fixed with a rear baffle 13. The guide rail 6 is preferably two symmetrically arranged.

[0053] Specifically, the flange plate and the screw rod 4 in the figure are both arranged on the front side of the bearing 8 with a slider seat, and their positions are not limited thereto, and they can also be arranged on the rear side of the bearing 8 with a slider seat. Of course, the flange plate and the screw rod 4 are not necessary, and the position of the bearing 8 with a slider seat can also be adjusted directly manually.

[0054] Furthermore, the frame 2 is supported by legs 3 , and the frame 2 is kept horizontal by adjusting the height of the legs 3 .

[0055] Furthermore, if Figure 6-Figure 7 As shown, the gear row 1 is fixed on the chain 15 through a small shaft 14, and the small shaft 14 penetrates the gear row 1 and the chain 15 in the width direction. It should be noted that the connection method between the gear row 1 and the chain 15 is not limited to this, and can also be a connection method such as welding. In addition, as common knowledge in the field, replacing the chain with a belt and the corresponding sprocket with a pulley to realize the movement of the gear row is also an alternative solution of the present invention.

[0056] The whole operation process of the alignment and feeding device is introduced as follows:

[0057] During the implementation process, the steel moves from the transmission shaft side to the driven shaft side, that is, from the back to the front, the alignment slider 16 is close to the driven shaft side, and the chain 15 moves synchronously with the gear row 1 at the same speed, and its movement speed can be adjusted according to the speed of the motor connected to the transmission shaft 5. The steel is placed between the first gear row and the second gear row near the transmission shaft 5 by manual lifting or direct transportation. Since it is placed directly, the front and rear ends of the steel are not aligned at this time, and the position is relatively random. As the chain and the gear row continue to move forward, the steel section is in direct contact with the chain. Due to the friction, the steel section will also move in the same direction (there is a certain degree of slippage in the movement of the steel section) until the front end of the steel section moves to the alignment slider 16. The alignment slider blocks the steel section from continuing to move forward (the blocking force is greater than the friction force). The front end of the steel section will not continue to move forward after contacting the alignment slider, but the chain and its upper gear row will still move forward at the original speed until the gear row contacts the rear end of the steel section. At this time, the thrust of the gear row on the steel section is greater than the blocking force of the alignment slider on the steel section. The rear end of the steel section is tightly attached to the gear row 1 and crosses the alignment slider 16, thereby ensuring that the end of each steel section is in contact with the gear row 1, achieving the alignment effect.

[0058] Due to the neatness of the alignment sliders on different frames and the neatness of the gear rows on different chains, the steel sections can be automatically aligned after crossing the alignment slider 16. All angle steels, bulb flat steels, and double-ball head bulb flat steels that pass through the automatic alignment feeding device are automatically aligned by adjusting the long sides of the alignment slider 16, and the steel sections are neatly fed.

[0059] In summary, the present invention provides an automatic alignment and feeding device for steel sections, which comprises at least two frames arranged in the width direction; each frame is fixed with an alignment slider at the same position on its upper surface, and a chain is arranged in a through groove of each frame along the length direction and can be rotated under the action of a driving force; a plurality of gear rows are fixedly connected to the chain, and the gear rows of each frame move synchronously, and the steel sections are placed across at least two frames. When the steel sections move forward under the action of the chain, the alignment slider can block the moving steel sections, and after the steel sections blocked by the alignment slider contact the gear row, they pass over the alignment slider under the push of the gear row, and finally, under the push of the gear row of each frame, the steel sections are corrected to be perpendicular to the length direction, and at the same time, the steel sections are contacted to achieve alignment. Due to the neatness of the alignment sliders on different frames and the neatness of the gear rows on different chains, the automatic alignment of the steel sections after crossing the alignment slider can be ensured, and the long sides of all steel sections such as angle steel, bulb flat steel, double ball head bulb flat steel, etc. that pass through the automatic alignment and feeding device are automatically aligned, and the steel sections are fed neatly, which is conducive to subsequent automatic grinding operations.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
