Safe door opening structure of marking machine

Abstract

The invention provides a safe door opening structure of a marking machine. The safe door opening structure of the marking machine is characterized by comprising a base of the marking machine, and a supporting frame, wherein a marking platform for positioning a marking object is arranged on the base; a covering housing is arranged on the base; the supporting frame is arranged on the base and is positioned in the covering housing; a door hole is formed in one side of the covering housing, and a door plate which can slide up and down is mounted on the door hole. The safe door opening structure ofthe marking machine further comprises a door driving motor which is arranged in the covering housing, and a transmission strip for connecting the door driving motor and a door board; the rotating output end of the door driving motor is in transmission connection with the transmission strip; the door driving motor drives the transmission strip to drive the door board to slide up and down. The safedoor opening structure of the marking machine further comprises a steel rope coiling device which is arranged at the upper end of the covering housing. According to the safe door opening structure ofthe marking machine, the transmission strip, a steel rope and an embedding guide rail structure are arranged, so that the door board can be directly connected to the covering housing; mechanical structures are matched with each other to drive a door to open and close; the structure and the mounting are simple; the flow process can be carried out, so that the practicability of the marking machineis improved; and meanwhile, the problem of potential risk in a door opening structure of the marking machine in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of marking machines, in particular to a safety door opening structure of the marking machine. Background technique [0002] Laser marking machine uses high-energy-density laser beams to irradiate the surface of various workpieces locally, so that the surface material of the material is rapidly vaporized or changes in color, thereby exposing the deep material, or causing chemical and physical changes in the surface material to engrave traces , or burn off part of the material through light energy, and display the desired etched graphics or text. [0003] More specifically, laser marking machines are mainly used in occasions that require finer and higher precision, such as electronic components, integrated circuits, mobile communications, hardware products, tool accessories, precision instruments, glasses clocks, jewelry, auto parts , building materials and other occasions. [0004] Existing laser marking ma...

Problems solved by technology

[0008] However, this structure only sets the conveyor chain to open or close the door. Since the conveyor chain drive in the marking machine generally uses a soft belt chain, this structure has disadvantages; for example, when the door panel is opened, the user Due to the operation, part of the user's limbs will extend into the marking machine to debug the equipment; due to the heavy weight of the marking machine's door itself, the belt chain often bears a large force, which increases the wear on the belt chain and may There will be a situation where the belt chain is broken and the door is smashed and closed, which has a greater safety hazard for the user; at the same time, the structure can only control the opening and closing of the door in an automatic way. failure (such as motor power failure), the door cannot be controlled by other methods (such as manual), so it is inconvenient to use
