The lifting drive assembly 122 is located below the swing wall and is installed on the material preparation rack 11 for lifting the swing arm 121 so that the lifting block 1211 can lift a material rod in the material storage trough 111 close to the upper material trough 112 out of the material storage trough 111. The material rods in the material storage trough 111 are sequentially filled in by the other material rods in the material storage trough 111, so that the material distribution and pushing mechanism 12 distributes the material rods in the material storage trough 111 to the material distribution trough 112 in sequence. The lifting drive assembly 122 includes a lifting cylinder 1221, a connecting rod 1222 and a plurality of V-shaped swing rods 1223. The lifting cylinder 1221 is fixed on the material preparation rack 11, and the driving rod of the lifting cylinder 1221 is connected to one end of the connecting rod 1222.

The clamping assembly 263 includes a clamping cylinder 2631, a push block 2632 and abutting blocks 2633. The abutting blocks 26 The second module 261 drives the material carrier 262 to move to a position close to the material preparation rack 11, and the push block 2632 and the abutment block 2633 are at a position far away from each other, and the material rods in the loading trough 112 fall into the push block 2633. The push block 2632 is driven by the clamping cylinder 2631 to move in the direction of the abutting block 2633 to clamp the material rod. The second module 261 drives the loading seat 262 to move in the direction of the cutting table 25 to push the clamped material rod onto the cutting table 25. The second module 261 and the clamping cylinder 2631 are both connected to the control system signal. When the material rod is cut, the clamping component 263 releases the clamping of the material rod and the second module 261 moves a certain distance in the direction of the storage rack for each cutting. After the cutting is completed, the clamping component 263 clamps the material rod again, and the second module 261 drives the loading seat 262 to move in the direction of the cutting table 25 to push the clamped material rod onto the cutting table 25 for cutting again. The above process is repeated until the material rod is cut. By adopting the above method to load the material rod to the cutting table 25, the automatic loading of the material rod is realized, and the consistency of the material rod cutting into segments is good.

[0030] Reference Figure 7The cutting table 25 is provided with a pressing assembly 251, a side pressing assembly 252 and a support block 253. The feeding end of the support block 253 is aligned with the clamping feeding mechanism 26. The clamping feeding mechanism 26 conveys the material rod to the support block 253. The support block 253 is on the moving path of the circular saw blade 241 and is provided with a cutting edge 2531 for the circular saw blade 241 to cut. When the circular saw blade feeds, it enters the support block 253 from the cutting edge 2531 to cut the material rod. The pressing assembly 251 includes a pressing cylinder 2511 and a pressing block 2512. The pressing block 2512 is located above the support block 253.

The side pressure cylinder 2523 is connected with the side pressure block 2522 to drive the side pressure block 2522 to reciprocate in the direction close to or away from the support plate 2521. The downward pressure cylinder 2511 and the side pressure cylinder 2523 are both connected with the control system signal. When the clamping feeding mechanism 26 conveys the material rod to the support platform, the side pressure cylinder 2523 drives the side pressure block 2522 to move in the direction of the support plate 2521 to push the material rod to the support plate 2521, and then the downward pressure cylinder 2511 drives the downward pressure block 2512 to move in the direction close to the support block 253, presses the top surface of the material rod, and fixes the material rod, so that the material rod is not easily displaced during cutting, and the cutting accuracy is high.

When there are a lot of waste chips in the waste chip collection hopper 281, the motor drives the spiral conveying rod 282 to rotate, and the spiral conveying rod 282 gradually pushes the waste chips toward the waste chip outlet 2811. When the waste chips reach the waste chip outlet 2811, they fall out of the waste chip collection hopper 281 and fall to the outside of the frame 21 for collection and cleaning.
