Abstract
The utility model provides a cutter cooling mechanism for a paper cutting machine. An energy separation device capable of separating one airflow into a cold airflow and a hot airflow is arranged beside a paper cutter, and a cold airflow output opening of the energy separation device faces the paper cutter. The cutter cooling mechanism has the advantages that the cold airflow output by the energy separation device is utilized for cooling the cutter, the cutter abrasion can be reduced, the service life of the cutter can be prolonged, in addition, the frequent replacement of the cutter is avoided, and the production efficiency is improved.
Description
Technical field
The utility model relates to paper roll production equipment, relates in particular to paper cutter.
Background technology
In the production process of paper roll, after a coil paper volume rewinding completes, must paper roll be cut into paper cutter to the some equal portions that meet cost length requirement.In the prior art, paper cutter is short of the mechanism of cooling cutter, the high temperature that cutter produces with paper roll high-speed friction in cut paper process, can make the hardness of cutting edge roundness diminish, thereby cause cutting edge roundness that wearing and tearing and chipping easily occur, seriously shortened the service life of cutter, except having increased maintenance cost, the frequent replacing of cutter also can reduce production efficiency.
Utility model content
The purpose of this utility model is to provide a kind of paper cutter cutter cooling body, the variety of issue bringing because producing high temperature in cut paper process to solve the cutter of paper cutter.
The utility model is achieved in that a kind of paper cutter cutter cooling body, is provided with the energy separation device that one flow separation can be become to hot and cold two strands of air-flows on the side of cut paper cutter, and the cold airflow delivery outlet of this energy separation device is towards cut paper cutter.
As preferred forms, described energy separation device is vortex tube cooler, and the cold airflow delivery outlet of vortex tube cooler is towards cut paper cutter.
The utility model has the advantages that, utilize the cold airflow of energy separation device output to lower the temperature to cutter, can reduce tool wear, extend cutter life, and avoided the frequent replacing of cutter, enhance productivity.The vortex tube cooler adopting in preferred forms also have advantages of low cost, non-maintaining, not electricity consumption, need not any chemical substance, do not have electric spark to produce, be not only environmental protection of one, safety but also device efficiently.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Referring to Fig. 1, a kind of paper cutter cutter cooling body of providing according to the utility model, comprises that one is arranged on cut paper cutter 1 side, can become one flow separation the energy separation device 2 of hot and cold two strands of air-flows.What in the present embodiment, energy separation device 2 adopted is vortex tube cooler.The cold airflow delivery outlet 3 of vortex tube cooler is towards cut paper cutter 1.When blast injection enters after vortex tube cooler 2, air-flow is at the interior High Rotation Speed of vortex tube cooler 2, form two strands of air-flows that inner ring temperature is low, outer ring temperature is high, the cold airflow of inner ring sprays to cutter 1 from cold airflow delivery outlet 3, carry out cooling to cutter 1, the thermal current of outer ring sprays in the opposite direction from thermal current delivery outlet 4, is lost in surrounding environment.The cold airflow delivery outlet 3 of vortex tube cooler 2 both can have been aimed at the cutting edge of cutter 1, also can aim at the temperature center of cutter 1, namely aimed at the highest position of cutter temperature rise, and this position is conventionally in the place of leaving main cutting edge certain distance.
According to actual needs, the utility model can arrange multiple energy separation device 2, together cutter is lowered the temperature by multiple energy separation device.
The utility model is not only applicable to illustrated circular cutter, is also applicable to the cutter of other shapes such as strip.
