Description

Technical Field

[0001] The invention relates to the technical field of slitting and creasing machines, and in particular to a displacement adjustment mechanism of a slitting and creasing machine and a use method thereof. Background Art

[0002] The slitting and creasing machine is a machine for slitting or creasing corrugated paper. The corrugated paper can be folded into cartons after slitting and creasing. Cartons of different specifications require corrugated paper to be slid and crimped in different sizes. Therefore, the knife group of the slitting and creasing machine needs to have a lateral adjustment function. The existing slitting machines on the market have a knife group that is laterally movable and sleeved on the knife drive shaft. The knife group and the knife drive shaft cooperate with each other through a key-keyway, so that the knife group can rotate with the knife drive shaft and can also move axially on the knife drive shaft. The slitting and creasing machine is also provided with a slide for moving the knife group. Each knife group corresponds to a slide, and the slide is usually driven by a screw mechanism to move laterally. Since the knife groups are not adjusted synchronously, this displacement adjustment mechanism requires each slide to be equipped with a set of screw mechanisms, which not only increases the production cost of the equipment, but also increases the difficulty of installation of the equipment. This is a problem that needs to be solved. Summary of the invention

[0003] The purpose of the present invention is to avoid the deficiencies of the prior art and provide a displacement adjustment mechanism and a use method of a slitting and crimping machine, thereby effectively solving the deficiencies in the prior art.

[0013] Furthermore, the circle counting wheel 51 is a gear, and a tooth groove is provided on one side of the positioning belt 22 that cooperates with the circle counting wheel 51 .

[0014] The method for using the displacement adjustment mechanism of the slitting and crimping machine includes the following steps: the push pin mechanism is activated to limit the rotation of the driving wheel, so that the driving wheel and the push pin mechanism are stationary relative to the slide seat; when the screw rotates, the driving wheel is restricted from rotating by the push pin mechanism; the first guide shaft serves as the guide shaft of the driving wheel, the push pin mechanism and the slide seat; the driving wheel, the push pin mechanism and the slide seat together form a screw structure that moves along the first guide shaft; when the slide seat needs to be moved, the corresponding push pin mechanism is activated to limit the rotation of the driving wheel at the corresponding position, so that the screw rod can be used to move multiple slides separately.

[0015] The above technical solution of the present invention has the following beneficial effects: the present invention can switch the sliding / stop state of the slide seat through the locking cooperation between the ejector pin mechanism on the slide seat and the drive wheel, so that multiple slide seats can slide in cooperation with a single screw rod separately, thereby reducing the production cost of the equipment, reducing the volume and weight of the equipment, and facilitating installation and use.
