[0033] The innovation of this application lies in the structural design of the material guide mechanism, combined with the attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 and attached Fig. 9 The material guiding mechanism includes a plurality of positioning holes 37 located on both sides of the upper surface of the workbench 1, a limit plate 38 is provided on both sides above the workbench 1, an avoidance opening 39 is provided at the lower end of the limit plate 38, a connecting plate 40 is installed on both sides of the lower surface of the limit plate 38, a connecting hole 41 is provided on the connecting plate 40, and the connecting plate 40 is installed on the positioning hole 37 by bolt connection, a plurality of rotating rods 42 are provided on both sides above the workbench 1, a third rolling bearing 43 is installed at both ends of the rotating rod 42, and the lower end of the third rolling bearing 43 is installed on the upper surface of the workbench 1, a square connecting opening 44 is provided on both sides of the rotating rod 42, and the plurality of rotating rods 42 are connected by a square telescopic rod 45, a plurality of rotating disks 46 are installed on the rotating rod 42, a plurality of receiving interfaces 47 are provided on the rotating disk 46, a rotating shaft 48 is provided at the receiving interface 47, and a fourth rolling bearing 49 is installed at both ends of the rotating shaft 48 , the fourth rolling bearing 49 is fixedly mounted on both sides of the receiving interface 47, an inclined baffle 50 is installed on one side of the upper end of the receiving interface 47, a fourth one-way bearing 51 is installed on one end of the rotating rod 42 closest to the feeding table 2, a third gear 52 is installed on the outside of the fourth one-way bearing 51, a fourth gear 53 is provided above the third gear 52, a transmission rod 54 is installed on the fourth gear 53, a fifth rolling bearing 55 is installed on one end of the transmission rod 54, the fifth rolling bearing 55 is fixedly mounted on the lower end of the feeding table 2, the lower end of the fourth gear 53 is meshed with the upper end of the third gear 52, fixed racks 56 are installed on both sides of the lower surface of the moving block 28, the lower end of the fixed rack 56 is meshed with the upper end of the fourth gear 53, when the cutting knife 30 moves, the transmission of the gear can drive the rotating rod 42 to rotate outward, and drive the steel bars to move, so that the steel bars can be collected conveniently.

[0034] In the present device, the electrical equipment of the device is controlled by an external controller. The length of the steel bar is cut as required, the limit plate 38 is moved to the specified position, the connecting plate 40 is placed on the workbench 1, and the connecting hole 41 and the positioning hole 37 are concentrically corresponding, and then the connecting plate 40 is installed on the workbench 1 using bolts. The length of the steel bar is cut as required, an appropriate amount of rotating rods 42 are selected, and the rotating rods 42 are connected using the square telescopic rod 45. When the square telescopic rod 45 is used, the square connecting rod 60 is moved into the square fixing hole 59, and the telescopic spring 61 is compressed, and then the square connecting rod 60 is placed at the square connecting port 44. Under the elastic force of the telescopic spring 61, the square connecting rod 60 can be pushed into the square connecting port 44, so that the two rotating rods 42 can be connected. When the square telescopic rod 45 needs to be removed, the staff uses a tool to insert one end of the tool into the square fixing hole 59. The limiting hole 62 can move the square connecting rod 60 into the square fixing hole 59, and compress the telescopic spring 61, so that the square connecting rod 60 can be taken out from the square connecting port 44, so as to facilitate the installation and disassembly of the square telescopic rod 45. This device is provided with two steel bar conveying lines. When the double-axis output motor 25 rotates forward, it can drive one steel bar conveying line to feed, which is named as the steel bar conveying line A. When the double-axis output motor 25 rotates reversely, it can drive the other steel bar conveying line to feed, which is named as the steel bar conveying line B. Under normal circumstances, a cutting knife 30 is located at the feeding hole 3 above the steel bar conveying line B and is blocked by the interception block 57 at the steel bar conveying line B. The other cutting knife 30 is located on one side of the feeding hole 3 above the steel bar conveying line A. The movable protective plate 80 is installed on both sides of the workbench 1 by bolt connection according to the length of the steel bar, and the collection box 81 is placed on the ground at the lower end of the inclined guide rod 78.

[0035] When in use, the straightened end of the steel bar is placed between the first feed wheel 11 and the second feed wheel 19 through the steel bar straightening machine, and the double-axis output motor 25 is started to rotate forward. The double-axis output motor 25 can drive the second bevel gear 26 to rotate, and the second bevel gear 26 is meshed with the first bevel gear 23, which can drive the first bevel gear 23 and the first one-way bearing 22 to rotate. The first one-way bearing 22 is installed on the first transmission shaft 7. According to the action of the first one-way bearing 22, the first one-way bearing 22 on the steel bar conveyor line A can drive the first transmission shaft 7 to rotate, and the first one-way bearing 22 on the steel bar conveyor line B can rotate outside the first transmission shaft 7. When the first one-way bearing 22 on the steel bar conveyor line A drives the first transmission shaft 7 to rotate, it can drive the first transmission gear 9 on the first transmission shaft 7 to rotate, and the first transmission gear 9 and the second transmission gear 17 are meshed, thereby driving the second transmission shaft 15 to rotate. When the first transmission shaft 7 rotates, under the action of the first transmission bearing 10, the first feed wheel 11 will not be driven to rotate, but the first toggle rod 13 can be driven to rotate. A toggle rod 13 can push the first intercepting rod 12, thereby causing the first feed wheel 11 to rotate. When the second transmission shaft 15 rotates, under the action of the second transmission bearing 18, it will not drive the second feed wheel 19 to rotate, but can drive the second toggle rod 21 to rotate. The second toggle rod 21 can push the second intercepting rod 20, thereby driving the second feed wheel 19 to rotate. One end of the steel bar is located between the first feed wheel 11 and the second feed wheel 19, thereby driving one end of the steel bar to enter from the feed hole 3 and fall onto the rotating rod 42. The steel bar falls from the receiving interface 47 onto the rotating shaft 48, and the rotating shaft 48 can rotate, thereby reducing the friction force when the steel bar is fed. The position of the steel bar is detected by the infrared ranging sensor 70. When one end of the steel bar is against the limit plate 38, the double-axis output motor 25 is turned off to rotate forward, and the steel bar feeding can be stopped. When the steel bar is fed, there is friction between the rotating rod 42 and the arc damping block 63. Under the elastic force of the compression spring 65, the friction force can be increased, thereby preventing the rotating rod 42 from rotating arbitrarily.

[0036] When the first one-way bearing 22 on the steel bar conveyor line B rotates outside the first transmission shaft 7, the first bevel gear 23 can be driven to rotate. When the first bevel gear 23 rotates, the friction between the first bevel gear 23 and the first transmission shaft 7 is increased through the L-shaped connecting shaft 71 and the friction pad 72, so that the first transmission shaft 7 can be driven to rotate. When the first transmission shaft 7 rotates, the first transmission gear 9 on the first transmission shaft 7 can be driven to rotate. The first transmission gear 9 and the second transmission gear 17 are meshed, and then the second transmission shaft 15 can be driven to rotate. When the first transmission shaft 7 rotates, the first toggle rod 13 can be driven to rotate. When the first toggle rod 13 rotates to the side of the first intercepting rod 12, due to the steel bar There is a large friction force between the first feed wheel 11 and the first feed wheel 11, which cannot make the first feed wheel 11 rotate, so that the first transmission shaft 7 can overcome the friction force between the first transmission shaft 7 and the friction pad 72, so that the friction pad 72 rotates outside the first transmission shaft 7, and will not drive the first transmission shaft 7 to rotate. When the second transmission shaft 15 rotates, it can drive the second toggle rod 21 to rotate. When the second toggle rod 21 rotates to the side of the second intercepting rod 20, due to the large friction force between the steel bar and the second feed wheel 19, the second feed wheel 19 cannot rotate. So the second transmission shaft 15 can overcome the friction force between the second transmission shaft 15 and the friction pad 72, so that the friction pad 72 rotates outside the second transmission shaft 15.

[0037] When the dual-axis output motor 25 rotates forward, the dual-axis output motor 25 can drive the second one-way bearing 31 to rotate, and the second one-way bearing 31 can drive the first gear 32 to rotate. When the cutting knife is located at the feed hole 3 at the steel bar conveying line B, the first gear 32 does not mesh with the first moving rack 33, and will not drive the moving block 28 to move. At this time, the second gear 35 is meshed with the second moving rack 36. When the dual-axis output motor 25 rotates forward, the rotating end of the dual-axis output motor 25 can rotate in the third one-way bearing 34, and the third one-way bearing 34 will not drive the second gear 35 to rotate, and the moving block 28 will not move.

[0038] After the steel bars are fed out of the steel bar conveyor line A, the double-axis output motor 25 is started to reverse, and the double-axis output motor 25 can drive the first transmission shaft 7 and the second transmission shaft 15 at the steel bar conveyor line A to rotate, and the first toggle rod 13 is rotated to the side of the first intercepting rod 12. After the second toggle rod 21 is rotated to the second intercepting rod 20, the first bevel gear 23 can continue to rotate, but the first transmission shaft 7 and the second transmission shaft 15 will not rotate. At this time, the first bevel gear 23 at the steel bar conveyor line B rotates and drives the first transmission shaft 7 and the second transmission shaft 15 to rotate. At this time, the first transmission shaft 7 and the second transmission shaft 15 will not immediately drive the first feeding wheel 11 and the second feeding wheel 19 to rotate. The first toggle rod 13 is rotated to the side of the first intercepting rod 12, and the second toggle rod 21 is rotated to the second intercepting rod 20, only then the first feed wheel 11 and the second feed wheel 19 are rotated. When the first transmission shaft 7 and the second transmission shaft 15 rotate and the first feed wheel 11 and the second feed wheel 19 have not yet rotated, the double-axis output motor 25 can rotate in the second one-way bearing 31 without driving the second one-way bearing 31 and the first gear 32 to rotate. The double-axis output motor 25 can drive the third one-way bearing 34 to rotate, and the third one-way bearing 34 can drive the second gear 35 to rotate, and move the moving block 28 to the side of the steel bar conveyor line A. The guide block 29 and the guide slide 27 can ensure that the moving block 28 The moving direction of the moving block 28 can make the cutting knife 30 on the side of the steel bar conveyor line A on the moving block 28 cut the steel bar at the steel bar conveyor line A and make it fall on the rotating shaft 48 above the rotating rod 42. Before the cutting knife 30 cuts the steel bar, when the moving block 28 moves, it can drive the limiting block 74 to move in the limiting groove 73 and move the arc-shaped positioning plate 76 toward the direction of the steel bar. The steel bar can give a reaction force to the arc-shaped positioning plate 76, which can compress the spring ejector pin 75, thereby facilitating the fixing of the steel bar and preventing the steel bar from shaking when cutting the steel bar. After the cutting knife 30 above the steel bar conveyor line B moves away from the feeding hole 3, the first feeding wheel 11 and the first feeding wheel 12 above the steel bar conveyor line B can be moved. The second feeding wheel 19 rotates, thereby feeding the steel bars. When the moving block 28 moves toward the steel bar conveying line A, the fixed rack 56 can be driven to move toward the steel bar conveying line A. The fixed rack 56 is meshed with the fourth gear 53, and the fourth gear 53 is meshed with the third gear 52, which can drive the third gear 52 and the fourth one-way bearing 51 to rotate. At this time, under the action of the fourth one-way bearing 51, the fourth one-way bearing 51 at the steel bar conveying line B can drive the rotating rod 42 to overcome the friction between it and the arc damping block 63 and rotate. After the rotating rod 42 has rotated completely, the steel bars can be fed. The fourth one-way bearing 51 at the steel bar conveying line A rotates on the outside of the rotating rod 42, which will not cause the rotating rod 42 to rotate.

[0039] After the steel bars at the steel bar conveyor line B are fed, the double-axis output motor 25 is started to rotate forward. The double-axis output motor 25 can first drive the moving block 28 to move in the direction of the steel bar conveyor line B, so that the steel bars above the steel bar conveyor line B can be cut off, and the cutting knife at the steel bar conveyor line A can be moved away from the feeding hole 3, and the rotating rod 42 at the steel bar conveyor line A can be driven to rotate, so that the steel bars can be moved to the other side, and the steel bars can fall into the collection box 81 under the action of the inclined baffle plate 50 and the inclined guide rod 78. The fixed protective plate 79 and the movable protective plate 80 can prevent the steel bars from falling outside the collection box 81 On the other hand, after the rotating rod 42 at the steel bar conveyor line A has completed its rotation, the moving block 28 no longer moves, and the first toggle rod 13 at the steel bar conveyor line A rotates to the side of the first intercepting rod 12, thereby allowing the first feed wheel 11 to rotate, and the second toggle rod 21 rotates to the side of the second intercepting rod 20, thereby driving the second feed wheel 19 to rotate, and feeding the steel bar conveyor line A. The first transmission shaft 7 and the second transmission shaft 15 at the steel bar conveyor line B do not rotate, and no feeding will occur. By continuously changing the forward and reverse rotation of the dual-axis output motor 25, the steel bars can be alternately fed, cut off and collected, which is convenient to use.

Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
