[0030] The specific usage and function of this embodiment are as follows:

[0031] In this utility model, when... Figure 1 As shown, when the preforming machine 1 is in use, the lifting pressure roller of the machine protective shell 2 is raised and disengaged from the outer circumference of the fixed mold cylinder 4 and the moving mold cylinder 8, as shown in the figure. Figure 3 As shown, the material is placed from the right end of the cantilever drive shaft 3 into the trapezoidal groove formed by the fixed mold cylinder 4 and the movable mold cylinder 8. The lifting pressure roller of the machine protective shell 2 is lowered and pressed against the outer circumference of the fixed mold cylinder 4 and the movable mold cylinder 8. Thus, the material is pre-formed through the trapezoidal groove formed by the fixed mold cylinder 4 and the movable mold cylinder 8. Figure 1As shown, when the movable mold cylinder 8 is adjusted, the locking anti-rotation pin 7 is engaged with the rotating adjustment cylinder 6 by rotating the tool. This causes the locking anti-rotation pin 7 to rise and disengage from the slot of the cantilever drive shaft 3 through the thread engagement, thereby releasing the locking anti-rotation pin 7 from preventing the rotation of the rotating adjustment cylinder 6. The rotating adjustment cylinder 6 is then engaged with the cantilever drive shaft 3 by rotating the tool. This causes the rotating adjustment cylinder 6 to move to the left or right through the thread engagement. The rotating adjustment cylinder 6 then drives the movable mold cylinder 8 to move to the left or right synchronously through the bearing, thereby adjusting the width of the trapezoidal slot formed by the fixed mold cylinder 4 and the movable mold cylinder 8.

[0032] Example 2:

[0033] The difference from Embodiment 1 is that the regular hexagonal prism of the mold fixing column 5 can also be set as a regular heptagonal prism, which makes the mold fixing column 5 require a special tool that works with the regular heptagonal prism to rotate, thus preventing non-workers from rotating and disassembling the mold fixing column 5.

[0034] Example 3:

[0035] The difference from Embodiment 1 is that the regular hexagonal groove of the locking anti-rotation post 7 can also be set as a regular heptagonal groove, so that the locking anti-rotation post 7 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-staff members from rotating and disassembling the locking anti-rotation post 7.
