[0024] Please see attached Figure 1 In a preferred embodiment, the feeding assembly includes: a vertical plate 6, there are four vertical plates 6, the four vertical plates 6 are vertically fixedly installed on the top of the vertical plate 6, and the four vertical plates 6 are divided into two groups, and two conveying rollers 3 are installed between each group of vertical plates 6 for rotation up and down, and four pulleys connected to the conveying rollers 3 are rotatably installed on the sides of the corresponding two vertical plates 6, and the surfaces of the corresponding two pulleys are sleeved with belts 5, and two first motors 4 connected to the conveying rollers 3 are installed on the sides of the corresponding vertical plates 6, and the rotation directions of the two first motors 4 are opposite, and the two first motors 4 are electrically connected to the copper plate 32 and the copper block 33; As mentioned above, the two first motors 4 drive the four conveying rollers 3 to work through the belt 5 and the pulley, so as to realize the conveying of the rods.

[0025] The working principle of the present invention is as follows: firstly, the roller bar of the motorcycle chain link is placed between the four conveying rollers 3, and then the two first motors 4 are powered on. At this time, the copper plate 32 and the copper block 33 are in contact, and then the two first motors 4 work to drive the four conveying rollers 3 to work through the belt 5 and the pulley, so as to realize the driving of the bar conveying; When the rod material contacts the detection plate 13, the detection plate 13 will be pushed to move. The movement of the detection plate 13 drives the fixed rod 29, the sliding rod 23 and the driving plate 18 to move, and the fifth spring rod 12 generates an elastic force. Then the first telescopic rod 24 will extend, and the driving plate 18 moves to drive the ramp block 26 to move. After the ramp block 26 contacts the connecting plate 15, the connecting plate 15 will move downward. Due to the limiting effect of the T-shaped plate 19 on the fixed block 25, the U-shaped plate 8 will not move downward at this time. At this time, the second spring rod 17 generates an elastic force and the first spring rod 16 generates a pulling force. The movement of the fixed rod 29 drives the copper block 33 and the sliding column 34 to move. At this time, the copper block 33 and the copper The plate 32 keeps in contact with the feeding assembly and keeps working. When the slide column 34 moves to the end of the isosceles trapezoidal groove 30, the telescopic end of the fourth spring rod 35 is located inside the inner groove 31, and the copper block 33 and the copper plate 32 are also separated and no longer in contact. Then the first motor 4 stops working, and the push plate 21 also contacts with the baffle 20 and pushes the baffle 20 to move. The movement of the baffle 20 drives the T-shaped plate 19 to move and causes the third spring rod 28 to generate elastic force. At this time, the T-shaped plate 19 no longer limits the fixed plate, and the elastic force generated by the second spring rod 17 causes the U-shaped plate 8 and its connecting parts to move downward together, and the further cutting disc 9 contacts with the bar material and cuts the bar material. The U-shaped plate 8 moves downward and also drives the first telescopic rod 24 to move downward. The first telescopic rod 24 moves downward and drives the slide bar 23 to move downward. As the cutting disc 9 moves downward, when the cutting disc 9 finishes cutting the bar material, the slide bar 23 enters the inclined section on the Z-shaped groove 22. It should be noted that the slide bar 23 does not enter the end of the Z-shaped groove 22, so that the detection plate 13 continues to move a little distance away from the U-shaped frame 2, so that the cut bar material can smoothly pass through the material discharge chute and fall into the material discharge box 11. When the cut rod material is unloaded, the elastic force generated by the fifth spring rod 12 will reset the detection plate 13 and move it in the direction close to the U-shaped frame 2. The detection plate 13 moves and drives the fixing rod 29, the driving plate 18 and the sliding rod 23 to move and reset. The movement of the driving plate 18 will separate the ramp block 26 and the connecting plate 15. Then the tension generated by the first spring rod 16 will cause the U-shaped plate 8 and its connecting parts to move upward together. The elastic force generated by the third spring rod 28 will also cause the T-shaped plate 19 to reset and continue to limit the U-shaped plate 8 through the fixing block 25. Due to the setting of the inner groove 31, when the fixing rod 29 drives the copper block 33 to reset, it will first move obliquely downward along the inner groove 31 as a path, so that the copper block 33 will not contact the copper plate 32 when resetting. When the sliding column 34 moves and resets to the end of the isosceles trapezoidal groove 30, the elastic force generated by the sixth spring rod will cause the sliding column 34 to be placed at the corresponding top of the isosceles trapezoidal groove 30. At this time, the copper plate 32 and the copper block 33 contact the feeding mechanism to continue to work and transport the rod material. In summary, the bar material can be cut automatically and continuously by reciprocating in sequence, thereby improving the cutting efficiency of the equipment.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
