[0027] Example 1:

[0028] See also Figure 1-5A flat steel feeder that prevents slipping includes a conveyor platform 1. A plurality of roller assemblies 2 are arranged at intervals along the length direction of the conveyor platform 1. Flat steel 3 is arranged on the plurality of roller assemblies 2. The flat steel 3 is rolled and supported by each roller assembly 2 for transmission and feeding. A vertical mounting plate 4 is provided on one side of the conveyor platform 1. The lower end of the mounting plate 4 is fixedly connected to the conveyor platform 1, and the upper end part is higher than the surface of the conveyor platform 1. A motor 41 is provided on the upper end of the mounting plate 4. The motor 41 is a servo motor. The motor 41 is horizontally fixed on the outer surface of the mounting plate 4. The output shaft of the motor 41 vertically passes through the mounting plate 4. The plate 4 extends to the top of the conveyor platform 1, and a turntable 42 is coaxially arranged on the output shaft of the motor 41. The turntable 42 is sleeved on the output shaft of the motor 41 through its center hole and coaxially fixedly connected through a flat key. An eccentric shaft 43 is eccentrically arranged on the outer end face of the turntable 42. One end of the eccentric shaft 43 is vertically fixedly connected to the end face of the turntable 42, and the other end is suspended. The eccentric shaft 43 is vertically rotatably connected to one end of the connecting rod 44. The connecting rod 44 is sleeved on the eccentric shaft 43 through a rotating hole set on its side. The outer wall of the suspended end of the eccentric shaft 43 is provided with an external thread and is connected with a limit nut to prevent the connecting rod 44 from The eccentric shaft 43 falls off, and the other end of the connecting rod 44 is hingedly connected to one end of the guide rod 45. The other end of the guide rod 45 is fixedly connected to the sliding block 5 set on the flat steel 3. A vertical guide hole 51 is set at the bottom of the sliding block 5, and a guide block 52 is set in the guide hole 51. A cylinder 53 is set on the sliding block 5, and the telescopic end of the cylinder 53 passes through the sliding block 5 and is connected to the guide block 52. A groove 54 is set at the bottom of the guide block 52, and an electromagnet 56 is set in the groove 54. The output shaft of the motor 41 is driven to rotate, which drives the turntable 42 to rotate. The turntable 42 rotates the first half circle and It drives the eccentric shaft 43 to rotate forward coaxially, and the rotation of the eccentric shaft 43 drives the connecting rod 44, the guide rod 45, and the sliding block 5 to move forward. During the forward movement of the sliding block 5, the flat steel 3 is sucked forward by the electromagnet 56, and the bottom of the flat steel 3 is supported by the roller 22 for rolling, and the whole moves forward for feeding. After the flat steel 3 moves to the end point of the stroke of the sliding block 5, the flat steel 3 can be intermittently fed forward at a fixed length. The flat steel 3 will not slip with the roller assembly 2, and the conveying efficiency and accuracy are high. The feeding process is highly automated, which saves manual labor intensity.

[0029] In this embodiment, see Figure 2 、 3 A horizontal positioning plate 57 is laterally arranged on the front end face of the sliding block 5, and two mounting holes are arranged at both ends of the positioning plate 57. Two vertical shafts 58 are vertically passed through the two mounting holes. The upper end of each vertical shaft 58 is fixedly connected to the positioning plate 57, and a roller 59 is rotatably arranged on each vertical shaft 58. The roller 59 is sleeved on the vertical shaft 58 through its axial through hole, and a retaining spring groove is provided on the outer wall of the vertical shaft 58 corresponding to the upper end of the roller 59. By arranging a retaining spring in the retaining spring groove, the rotation of the roller 59 is restricted on the vertical shaft 58. The two rollers 59 are used to facilitate the directional conveying of the flat steel on the roller assembly 2.

[0030] In this embodiment, see Figure 4 、 5 Two vertical mounting grooves 50 are provided on the bottom surfaces of the front and rear ends of the sliding block 5, and a positioning hole 501 is provided at the bottom of each mounting groove 50. A movable rod 502 is passed through the positioning hole 501 to guide the sliding fit. The lower end of the movable rod 502 extends downward into the mounting groove 50 and is fixedly connected to the middle part of the horizontally arranged fixed shaft 503 in the mounting groove 50. Two rolling bodies 504 are rotatably provided at both ends of the fixed shaft 503. Each rolling body 504 is cylindrical and is sleeved on the fixed shaft 503 through its axial through hole. A retaining spring is provided on the outer wall at both ends of the fixed shaft 503 to limit the two rolling bodies 504 to the fixed shaft 503 and can only rotate along the fixed shaft 503.

[0031] In this embodiment, see Figure 4 、 5 , a spring 505 is sleeved on the movable rod 502, and the spring 505 is a compression spring. One end of the spring 505 is elastically fixedly connected to the bottom of the installation groove 50, and the other end is elastically fixedly connected to the shoulder 506 set on the outer wall of the movable rod 502. After the sliding block 5 contacts the flat steel 3, the rolling body 504 retracts into the installation groove 50, and the fixed shaft 503 and the movable rod 502 move upward, so that the spring 505 is in a compressed state. When the sliding block 5 needs to be separated from the flat steel 3, the rolling body 504 is driven by the spring 505 to support the sliding block 5, so that the sliding block 5 can reduce friction and return to the starting point.

[0032] In this embodiment, see Figure 1 The roller assembly 2 includes a bracket 21 and a roller 22 rotatably arranged on the bracket 21. A rubber layer is arranged on the outer wall of the roller 22 to increase the friction between the roller 22 and the flat steel 3 to prevent the flat steel 3 from slipping with the roller 22 during the feeding process.

[0033] In this embodiment, the motor 41, cylinder 53, and electromagnet 56 are all existing commercially available equipment and are programmed and controlled by the controller so that the motor 41 rotates according to the set feeding speed, and the cylinder 53 can drive the electromagnet 56 away from or close to the flat steel 3 in a relatively short time.

[0034] It can be seen from the above technical solution that when in use, first, the flat steel 3 is transported to the bottom of the sliding block 5 through multiple roller assemblies 2, and the two sides of the flat steel 3 are restricted in the middle by two rollers 59. The cylinder 53 is controlled by the controller to drive its telescopic end to drive the guide block 52 to move downward along the guide hole 51 until the bottom surface of the guide block 52 is in contact with the surface of the flat steel 3. The electromagnet 56 is energized by the controller. The electromagnet 56 is energized to obtain electromagnetic attraction and absorb the flat steel 3. During the process, the rolling body 504 is forced to retract into the installation groove 50. At the same time, the fixed shaft 503 drives the movable rod 502 to move upward to compress the spring 505. Then, the motor 41 is controlled by the controller to drive its output shaft to rotate, driving the turntable 42 to rotate. The turntable 42 rotates the first half circle and drives the eccentric shaft 43 to rotate forward coaxially. The rotation of the eccentric shaft 43 drives the connecting rod 44, the guide rod 45, and the sliding block 5 to move forward. During the forward movement of the sliding block 5, the electromagnet 56 The flat steel 3 is sucked and moves forward. The bottom of the flat steel 3 is supported by the roller 22 and moves forward as a whole to feed the material. After the flat steel 3 moves to the end of the stroke of the sliding block 5, the controller controls the electromagnet 56 to cut off the power, and at the same time controls the cylinder 53 to drive its telescopic end to drive the guide block 52 to move upward along the guide hole 51, so that the electromagnet 56 is away from the flat steel 3 and no longer contacts it. Under the elastic force of the spring 505, the movable rod 502 drives the fixed shaft 503 and the rolling body 504 to move downward, and causes the rolling body 504 to partially leak out of the mounting groove 50, so that the bottom surface of the sliding block 5 does not contact the upper surface of the flat steel 3. Then, the turntable 42 rotates the second half circle and drives the eccentric shaft 43 to rotate backward coaxially. The rotation of the eccentric shaft 43 drives the connecting rod 44, the guide rod 45, and the sliding block 5 to move backward. During the backward movement of the sliding block 5, it contacts the upper surface of the flat steel 3 through the rolling body 504 until the sliding block 5 moves to the starting point of the stroke, and then repeats the above steps for the next feeding.
