Abstract

The utility model discloses a device for eliminating static electricity in a dividing and cutting machine through point discharge. The device for eliminating the static electricity in the dividing and cutting machine through the point discharge comprises a machine frame, wherein an uncoiling roll and a conveying roll are arranged on the machine frame; a knife blade fixing beam is arranged above a space between the uncoiling roll and the conveying roll; knife blades are distributed on the knife blade fixing beam; the device for eliminating the static electricity in the dividing and cutting machine through the point discharge is characterized in that an electrostatic protection box is arranged on the machine frame between the knife blade fixing beam and the uncoiling roll; discharge needles are distributed on the electrostatic protection box; the discharge needles are aligned with a film between the knife blade fixing beam and the uncoiling roll; a control circuit board is arranged inside the electrostatic protection box; and the electrostatic protection box is grounded through a conductive wire. The device for eliminating the static electricity in the dividing and cutting machine through the point discharge is reasonable in design, can eliminate the static electricity generated by a plastic film running in the dividing and cutting machine at a high speed through the point discharge, avoids safety hazards caused by the static electricity, does not cause a short circuit phenomenon of equipment and ensures the normal running of the production.

Description

Utilize the destaticizing device of point discharge in a kind of cutting machine

Technical field

The utility model relates to the light industry field of printing machinery, relates in particular to the destaticizing device that utilizes point discharge in a kind of cutting machine.

Background technology

In printing industry, particularly in the printing process of plastic film packaging bag, just carry out chromatography on the color press manufacturing line with plastic sheeting; Chromatography is directly carried out rolling after well, need cut on cutting machine according to corresponding size plastic sheeting after the rolling, existing cutting machine in cutting process mostly be through unreel, cut, the process of rolling; Plastic sheeting is easy to generate static or spark in the process in the high-speed operation process, the people near the time have a potential safety hazard; Printer mostly adopts associated metal parts such as metal bin simultaneously, and static is easy to pass in the mechanical equipment, also occurs short circuit phenomenon easily; Influence ordinary production; Mostly adopted conductive fiber to eliminate static in the past, bad but it eliminates effect, inefficiency.

The utility model content

The purpose of the utility model is in order to remedy the deficiency of prior art; The destaticizing device that utilizes point discharge in a kind of cutting machine is provided; Utilize point discharge to eliminate the static that plastic sheeting produces in the running; Avoid potential safety hazard, can not cause the equipment short circuit phenomenon simultaneously, guaranteed normal, the high-speed cruising produced.

The utility model is realized through following technical scheme:

Utilize the destaticizing device of point discharge in a kind of cutting machine; Include frame, said frame is put on the shelf and is provided with let off roll, conveying roller, and the blade fixed beam has been set up in the top between said let off roll, the conveying roller; Be distributed with blade on the said blade fixed beam; It is characterized in that: the frame between said blade fixed beam and the let off roll is put on the shelf and is provided with the electrostatic defending box, is distributed with spray point on the said electrostatic defending box, and said spray point is on the film between blade fixed beam and the let off roll; Be provided with control circuit board in the said electrostatic defending box, and through lead ground connection.

Frame between described blade fixed beam and the let off roll is put on the shelf and is provided with mutual cooresponding electrostatic defending box; Film between said blade fixed beam and the let off roll is between two electrostatic defending boxes; And one of them electrostatic defending box is wired to power supply, and the testing circuit plate is installed in it, and another electrostatic defending box is through lead ground connection; Be distributed with spray point on its box body, be provided with in the box body and testing circuit plate bonded assembly control circuit.

Its principle is: through the needle point discharge of the spray point on the electrostatic defending box; Eliminate the static of the plastic sheeting generation of high-speed cruising on the let off roll; It is directly imported ground connection eliminate static; The potential safety hazard of having avoided static to bring can not cause the equipment short circuit phenomenon simultaneously, has guaranteed the normal operation of producing; And the design through the testing circuit plate in another electrostatic defending box; Whether have electric charge in operation, prevent that the most advanced and sophisticated static of eliminating from continuing discharge afterwards, influences static and eliminate if can detect operation volume plastic sheeting; After whether electric charge being arranged after the testing circuit plate detects simultaneously; Signal is passed to control circuit,, static is eliminated reached better effect through increasing or reduce the number of spray point.

The utility model has the advantages that:

The utility model is reasonable in design, eliminates the static that the plastic sheeting of cutting machine high speed operation produces through point discharge, and the potential safety hazard of having avoided static to bring can not cause the equipment short circuit phenomenon simultaneously, has guaranteed normal, the high-speed cruising produced.
