The conical movable block 15 is truncated cone-shaped, and the size of one end close to each other is smaller than the other side, so as to guide the entry of the cardboard, so that the cardboard is in the center position of the device and cannot be offset or moved. A connecting block 16 is provided on the inner side of the conical movable block 15, and a sliding sleeve 17 is provided on the inner side of the connecting block 16. The sliding sleeve 17 is concentric with the conical movable block 15, thereby ensuring that the conical movable block 15 and the sliding sleeve 17 are a whole, which is convenient for overall movement. The connecting block 16 passes through the notch 14, and the sliding sleeve 17 is placed inside the guide roller 13.

[0024] Please refer to Figure 2As shown, a double-threaded rod 18 is installed inside the guide roller 13 through a bearing, and one end of the double-threaded rod 18 passes through the surface of one side of the workbench 1, and a control wheel 19 is arranged at the end of the double-threaded rod 18. The control wheel 19 is placed on the outside of the workbench 1 so as to control the double-threaded rod 18 from the outside. The double-threaded rod 18 passes through the sliding sleeve 17, and there is no contact between the double-threaded rod 18 and the sliding sleeve 17. An extrusion block 20 is symmetrically and slidably installed on the surface of the double-threaded rod 18, and the extrusion block 20 is placed on the inside of the guide roller 13, and the two extrusion blocks 20 are respectively placed on the outside of the two conical movable blocks 15.

When the extrusion blocks 20 approach each other, the conical movable block 15 can be driven to approach to adapt to the processing of small-sized products. Conversely, when the extrusion blocks 20 move away from each other, the conical movable block 15 can be moved away from each other, while ensuring that the two conical movable blocks 15 are symmetrical relative to the center of the guide roller 13, and the product passes through the surface of the guide roller 13 and enters between the lower pressure roller 11 and the upper pressure roller 10. Rotate the control hand wheel 9 to drive the screw 5 to rotate through the cooperation of the belt 8 and the pulley 7, and then adjust the height of the lifting block 6 to control the extrusion force of the upper pressure roller 10 on the product.
