Abstract
A cutting apparatus is provided for cutting a sheet material. The cutting apparatus includes a bed for resting thereon the sheet material, a hollow rail structure spaced from the bed, a cutting element moved along the hollow rail structure to travel on the sheet material and cut it in a desired manner, a holding plate coupled to the hollow rail structure for depressing the sheet material on the bed to facilitate the cutting operation of the cutting element, and a sustaining element disposed in the hollow rail structure. The sustaining element sustains against an upper inner surface of the hollow rail structure to lift up the holding plate and sustains against a lower inner surface of the hollow rail structure to put down the holding plate.
Claims22
A cutting apparatus, comprising:
- a bed for resting thereon a sheet material;
- a hollow rail structure disposed above and spaced from said bed;
- a cutting element moved along said hollow rail structure to travel on said sheet material resting on said bed so as to cut said sheet material in a desired manner;
- a holding plate coupled to said hollow rail structure for pressing against said sheet material resting on said bed so as to facilitate the cutting operation of said cutting element;
- and
- an eccentric cam having a shaft and disposed in said hollow rail structure for sustaining against a lower inner surface of said hollow rail structure so as to push down said holding plate to depress said sheet material in response to a first operation working thereon, wherein said hollow rail structure has a through hole for penetrating through two opposite end surfaces thereof, and said eccentric cam having a shaft penetrates said through hole.
A holding device for use in a sheet-processing apparatus having a bed resting thereon a sheet material to be held, comprising:
- a supporter structure secured onto said bed;
- a hollow rod with two ends supported by said supporter structure to be spaced from said bed;
- a holding plate coupled to said hollow rod for pressing against said sheet material to be held on said bed;
- an eccentric cam having a shaft and disposed in said hollow rod for lifting up said holding plate to release said sheet material in response to a first operation working thereon, and pushing down said holding plate to depress said sheet material in response to a second operation working thereon;
- and
- a handle pivotally coupled to said supporter structure and securely connected to said shaft of said eccentric cam, said handle being pivoted to change the orientation of said eccentric cam having a shaft in said hollow rod so as to conduct said first and second operations, wherein said hollow rod has a through hole penetrating through two opposite end surfaces thereof, and said eccentric cam having a shaft penetrates said through hole.
A holding device for use in a sheet-processing apparatus having a bed resting thereon a sheet material to be held, comprising:
- a hollow rail structure disposed above and spaced from said bed;
- a holding plate coupled to said hollow rail structure for pressing against said sheet material resting on said bed so as to facilitate the operation of the sheet-processing apparatus;
- and
- an eccentric cam having a shaft and disposed inside said hollow rail structure for sustaining against a first inner surface of said hollow rail structure so as to lift up said holding plate to release said sheet material or sustaining against a second inner surface of said hollow rail structure so as to push down said holding plate to press said sheet material against said bed, wherein said hollow rail structure has a through hole penetrating through two opposite end surfaces thereof, and said eccentric cam having a shaft penetrates said through hole.
