Description

Ultrasonic indentation cutting mechanism

Technical field

The utility model relates to cutting and impression machinery of a kind of pictorial trademark.

Background technology

General commodity label all is a segment-like, and its surface is embroidered with or is printed on trademark, for making or stick on the commodity, comes the brand of display of commodity, and aforesaid segment-like trademark is to be cut in the strip braid over braid by the trade mark guillotine to form.Frequent being seen trade mark cutting machine, constitute by cutting knife, knife rest, stepper motor and eccentric wheel, its stepper motor is rotated by square both direction, the drive eccentric wheel moves back and forth, and drive knife rest cutting knife is moved back and forth, the cutting machine of this structure, after stepper motor is just changeing, reverse again, make that the reciprocating time interval is long, reduced production efficiency.Thereby, those skilled in the art make improvements again, motor is rotated in one direction, its cutting knife is pumped by the synchronous interlock of the knife rest of driven by motor, with the cutting trade mark, but the cutting knife cutting action of this guillotine often is difficult to keep plateau as usually, in case cutting knife is because of slightly can't tight connecting with the support that bears trade mark, the cutting of trade mark often has burr to produce, even can't completely cut, What is more, and cutting knife is heated with electric heater, easily cause the burr during except that cutting, the sheet trade mark is because of the molten trade mark yellowing to cutting of hot melt during cutting.So those skilled in the art improve again.Look into Chinese patent database, obtaining a notification number is CN2683341Y, name is called the utility model patent of " ultrasonic cuts off the automatic cutter presetter of trade mark ", disclose following content: a kind of ultrasonic cuts off the automatic cutter presetter of trade mark, it is characterized in that: in the two pairs of corresponding guide pin bushings of on the support of board bottom surface, erectting in the left and right sides and the space between guide pillar, one turning cylinder by the transmission of motor institute is set, be connected with cam on the described turning cylinder, drive turning cylinder interlock cam actuated base by motor and pump; Its base top is connected with two springs, and two springs top is connected with cutting knife, and the cutting knife top is for being fixedly arranged on the ultrasonic mould on the board.The trade mark cutting machine of this structure has solved problem recited above to a certain extent, still, need be on sign during impression when some trade mark, the machine of this structure just need rotate and reverse motor, and is like this, just reduced production efficiency.Simultaneously, after cutting blade abrasion, need to shut down disassembling, assembling and replacing, very trouble.

Summary of the invention

In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides a kind of ultrasonic indentation cutting that can carry out impression again when cutting off on trademark and carry out the school cutter at any time.

For this reason, adopt following technical scheme to realize during the utility model: a kind of ultrasonic indentation cutting mechanism, have body, supersonic mould, cutting knife, knife rest and mount pad, first motor is installed on the described mount pad, described cutting knife and described supersonic mould are oppositely arranged, described cutting knife is installed on the knife rest, it is characterized in that described knife rest is connected with first eccentric wheel by first connecting rod, the rotating shaft of described first eccentric wheel and described first motor is in transmission connection, and described mount pad is connected with second transmission device; Described second transmission device comprises second connecting rod, second eccentric wheel and second motor, and an end of described second connecting rod connects described mount pad, and the other end connects described second eccentric wheel, and the rotating shaft of described second eccentric wheel and described second motor is in transmission connection; Described second transmission device of the present utility model can also be to comprise screw mandrel, nut and second motor, and described nut is installed on the described mount pad, and is enclosed within on the described screw mandrel, and described screw mandrel and described second motor are in transmission connection; Be provided with feed mechanism on body, the conveyer belt and the stepper motor of described feed mechanism are in transmission connection; The below of described knife rest is provided with spring, and an end of this spring contacts with described knife rest.

In the utility model, owing to be provided with second transmission device, the work of its second transmission device can drive mount pad integral body and pump, therefore, when the sheet trade mark places on the supersonic mould, the second transmission device work can drive mount pad and move down, and just can make cutting knife leave supersonic mould and have certain clearance, after first machine operation, when cutting knife is risen, can carry out impression to trademark, behind the impression, the second transmission device return, send a segment distance by feed mechanism, by first driven by motor, first eccentric wheel, make that knife rest and cutting knife are up again, contact with supersonic mould, finish the cut-out function.Simultaneously, the work of second transmission device also can make mount pad rise, after the cutting blade abrasion, fine setting is done in the gap of cutting knife and supersonic mould, guaranteed that cutting knife normally cuts, whole process stabilization smoothness cuts with the speed of impression and school cutter soon, has improved production efficiency to the full extent.
