At the same time, the position of the second protective pads 6 is in the same horizontal plane as the position of the corresponding shock-absorbing pads 416. The second protective pads 6 and the shock-absorbing pads 416 are used in combination, so that when the flip plate 401 is flipped to unload the rods, the collision with the rods is reduced, and the protection of the flip plate 401 is improved and the noise is reduced.

[0031] according to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a feeding port 102 is provided on the other side of the support platform 1, and a conveying frame 7 is obliquely provided at the bottom of the feeding port 102, and at the same time, the other end of the conveying frame 7 is engaged with a mounting groove provided at one side of the upper end of the collecting box 8, and a buffer pad 701 is provided inside the conveying frame 7 located below one side of the feeding port 102, so that the rods discharged from the feeding port 102 have a certain buffering protection and noise reduction effect, and a first electric telescopic rod 9 is symmetrically provided at the bottom of the conveying frame 7, and at the same time, the output end of the first electric telescopic rod 9 is connected to the partition The lower end of the partition frame 10 is connected, the upper end of the partition frame 10 passes through the conveying frame 7 and extends to the upper part of the conveying frame 7, and the upper end of the partition frame 10 is located on the outside of one end of the buffer pad 701. The partition frame 10 is driven to move up and down by the first electric telescopic rod 9, which is convenient for limiting the rods on the buffer pad 701, preliminarily collecting the rods and sorting out their placement problems, and improving the flatness of the later rod collection. The collection box 8 is installed on the other side of the upper end of the base 2, and a placement component 11 is arranged inside the collection box 8 for placing and bundling the cemented carbide rods.

[0032] Specifically, the placement component 11 includes a placement seat 1101 and an electric hydraulic cylinder 1102, and the middle of the lower end of the placement seat 1101 is connected to the lower end of the collection box 8 through a symmetrically arranged electric hydraulic cylinder 1102, and at the same time, the two sides of the placement seat 1101 are connected to the guide slide rails 801 correspondingly arranged on the inner side of the collection box 8. The placement seat 1101 is driven to move on the guide slide rails 801 by the electric hydraulic cylinder 1102, so that the height of the placement seat 1101 can be adjusted according to the usage, so as to facilitate the placement and unloading of rods. The upper end of the placement seat 1101 is away from the conveying frame 7 and is equidistantly connected to a plurality of limit baffles 1104. The limit baffles 1104 have a certain blocking effect after the rods are unloaded into the collection box 8, so as to avoid the collision of the rods with the collection box 8 due to the rolling of the rods, which affects the quality of the rods and shortens the service life of the collection box 8, and one side of the limit baffle 1104 is detachably connected with a strap 1105, and a sound-absorbing pad is arranged on the top of the upper end of the placement seat 1101 1103, through the sound-absorbing pad 1103, the sound generated by the rolling of the rods is reduced, and the noise pollution is reduced.

The top of the limit stop frame 1108 penetrates the placement seat 1101 and the silencer pad 1103 and extends to above the silencer pad 1103. The limit stop frame 1108 is driven to move up and down by the second electric telescopic rod 1107, which is convenient for limiting the positioning of multiple bars, improving the stability of the bars when bundling, and avoiding the bars from falling off during bundling, which affects the quality and appearance of the bars.

[0033] When in use, the formed rod is cut and placed on the upper end of the support seat 411, and then the main bidirectional screw rod 406 is driven to rotate by the driving motor 405, and the double pulley 407 arranged on the main bidirectional screw rod 406 drives the single pulley 409 and the side bidirectional screw rod 410 to rotate through the transmission belt 408, so that the side clamping plate 414 moves to one side of the support seat 411, and then the rubber pad 415 fits with the side of the rod to clamp it, and then the rotating motor 404 drives the rotating shaft and the connecting piece 402 to rotate, so that the flip plate 401 connected to the connecting piece 402 is flipped, and the shock-absorbing pad 416 fits with the upper end of the second protective pad 6, and then the rod is located above the middle of the discharge port 102, and then the main bidirectional screw rod 406 is driven to rotate in the opposite direction by the driving motor 405, and the double pulley 407 arranged on the main bidirectional screw rod 406 drives the single pulley 409 and the side bidirectional screw rod 410 to move forward through the transmission belt 408. The rods are placed on the upper end of the silencer pad 1103 under the action of the limit baffle 1104. When the number of rods placed on the upper end of the silencer pad 1103 reaches a certain number, the second electric telescopic rod 1107 is started to drive the limit baffle 1108 to move upward to limit the position of multiple rods. Then, the electric hydraulic cylinder 1102 is started to drive the placement seat 1101 to move upward on the guide rail 801 so that the placement seat 1101 is located at the upper end of the collection box 8. Then, one end of the strap 1105 is connected to the other end connected to the limit baffle 1104 to bundle the rods. After bundling is completed, the second electric telescopic rod 1107 drives the limit baffle 1108 to move downward to facilitate the unloading of the bundled rods.
