[0030] Among them, the adjusting component 8 includes a guide groove 81 opened at the end of the horizontal rotating frame 3 and the vertical rotating frame 6 away from the guide roller and a plurality of sliding rods 82 slidably arranged inside the first guide seat 2 and the second guide seat 5. The plurality of sliding rods 82 are distributed in a circle and are fixed with guide rods 83. In this embodiment, the sliding between the sliding rod 82 and the first guide seat 2 and the second guide seat 5 ensures the movement stability of the guide rod 83 and the local threaded block 84 after being screwed with the internal thread 86.

[0031] Among them, the guide rod 83 penetrates and slides in the guide groove 81, and the horizontal rotating frame 3 and the vertical rotating frame 6 rotate synchronously at the same angle through the sliding of the slide rod 82 inside the guide groove 81. In this embodiment, the guide grooves 81 on the horizontal rotating frame 3 and the vertical rotating frame 6 are in different directions, so that the guide rod 83 can simultaneously drive the vertical rotating frame 6 and the horizontal rotating frame 3 to rotate in different directions during the movement in one direction.

[0032] Among them, the outer ring of the guide rod 83 is provided with a circumferentially distributed local thread blocks 84, and a rotating sleeve 85 is rotatably installed between the first guide seat 2 and the second guide seat 5. An internal thread 86 is arranged inside the rotating sleeve 85. The local thread block 84 is threadedly matched with the internal thread 86, and the slide rod 82 slides in the guide groove 81 through the spiral of the local thread block 84 and the internal thread 86. In this embodiment, the thread between the local thread block 84 and the internal thread 86 is used as a drive, which is convenient for operation. At the same time, the thread structure also has the advantages of high adjustment accuracy and convenient operation.

[0033] Among them, a circumferentially distributed shifting rod 87 is provided on the outside of the rotating sleeve 85, and the shifting rod 87 rotates with the rotating sleeve 85. The locking component 9 is installed on the first guide seat 2 and cooperates with the shifting rod 87. In this embodiment, the shifting rod 87 is distributed in a circle, and the position of each shifting rod 87 cooperates with the diameter of materials of different sizes. When each shifting rod 87 is locked with the locking component 9, multiple guide rollers are adjusted to the aperture that cooperates with the corresponding material, thereby improving the adjustment coordination degree.

[0034] Among them, the locking component 9 includes a locking plate 91 and a shift block 92 fixed at one end of the locking plate 91, and a locking spring 93 arranged between the locking plate 91 and the first guide seat 2. One end of the locking plate 91 is formed with a groove that cooperates with the shift rod 87 and is locked with the shift rod 87 under the action of the locking spring 93, and the other end slides inside the first guide seat 2. In this embodiment, the locking component 9 set can lock the guide roller position adjusted to the corresponding position by the adjusting component 8, thereby ensuring the stability of the guide roller after adjustment.

[0035] It can be understood that the adjusting component 8 provided first can realize the simultaneous adjustment of the positions of the two horizontal guide rollers 4 and the two vertical guide rollers 7, and the axial position of the front and rear of the adjustment channel is consistent, thereby ensuring the adjustment consistency and accuracy of the guide rollers. Secondly, the locking component 9 provided can lock the adjusting component 8 of the corresponding size according to the different sizes of the materials required to pass through.

[0036] A specific application of this embodiment is: the horizontal rotating frame 3 and the horizontal guide roller 4 are two symmetrical groups, the vertical rotating frame 6 and the vertical guide roller 7 are also two symmetrical groups, the four guide rollers are equidistantly distributed on the circumference, the guide grooves 81 at the rear ends of the horizontal rotating frame 3 and the vertical rotating frame 6 are simultaneously connected to the guide rods 83, and the levers 87 are arranged in a circle, and the locking position of each lever 87 is consistent with the material of the corresponding diameter;

[0037] In actual use: the lock plate 91 and the lever 87 are pushed out of the lock by the lever block 92, and the locking spring 93 is compressed at this time. The rotating sleeve 85 is rotated by the lever 87, and the internal thread 86 and the horizontal guide roller 4 generate a spiral. Since the two ends of the rotating sleeve 85 are respectively in contact with the first guide seat 2 and the second guide seat 5, axial movement cannot be generated. The moving force generated by the spiral promotes the axial movement of the local thread block 84. During the axial movement of the local thread block 84, the slide bar 82 follows the first guide seat 2 and the second guide seat 5 and slides in the same direction The local threaded block 84 drives the guide rod 83 to move inside the guide groove 81. Since the guide groove 81 is inclined, it will drive the horizontal rotating frame 3 and the vertical rotating frame 6 to rotate at the same time, and can overcome the position difference after rotation. At this time, the through apertures of the two horizontal rotating frames 3 and the two vertical guide rollers 7 are adjusted synchronously. After the adjustment is completed, the corresponding lever 87 is located in the matching position with the locking plate 91. After the lever block 92 is released, the lever 87 is locked under the action of the locking spring 93, and then the adjusted multiple guide rollers are locked at the same time.
