Winding type laser marking machine

Abstract

The invention discloses a winding type laser marking machine comprising a main body stand, a laser machine installed on the main body stand, and a control system. A laser working platform is arranged below the laser machine. The winding type laser marking machine is characterized by further comprising a material conveying device which is spliced into a material conveying runway at a same plane with the operation surface of the working platform; at least one gravitation rod is arranged between the working platform and a tension adjusting mechanism and is connected to the material conveying runway in a spanning mode; the bottom of the gravitation rod is abutted on the surface of a material positioned on the material conveying runway; and a sensor mechanism is arranged near the feeding position of the working platform, acquires signals of printing medium positioned on the material conveying runway and inputs the signals to the control system which is a control device with programmable software. The invention realizes the continuous automatic printing of high-precision laser labels through the arrangement of the material conveying device, the sensor mechanism and the gravitation rod and effectively improves the printing efficiency and the use range.

Description

technical field [0001] The invention relates to a label printer, in particular to a laser marking type label printer which prints labels through a laser. Background technique [0002] Label printers have different printing methods, laser type and thermal transfer type, both of which have different printing effects and have their own advantages and disadvantages. [0003] Laser marking technology is one of the largest application fields of laser processing. It is a kind of marking that uses high-energy-density laser to partially irradiate the medium to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. With this method, various characters, symbols and patterns can be printed, and the character size can reach the micron level. Existing laser marking machines include a frame, and a computer control system and a laser fixed on the frame. The computer control system controls the laser to mark the work placed on the wor...

Problems solved by technology

However, there is a certain distance between the sensor and the thermal head in charge of recording, and it usually needs to be separated by several positions for printing labels, so the accuracy rate is lower than that of laser marking machines, and it is impossible to complete fine label printing, especially in multiple In the first positive and negative overprinting, the accuracy will not meet the label requirements, and even cannot be completed; in addition, when the distance between adjacent labels is not equal, the machine will stop printing because the next printing position cannot be accurately determined, so for a single label Paired labels with small gaps and large gaps between adjacent labels cannot be printed due to the difference in spacing
