Abstract
Description
[Technical Field]
[0001] The present invention relates to a smock removal nozzle structure for a laser processing machine, and in particular to a laser processing machine that effectively removes smock and prevents atomization caused by smock accumulation when processing using laser output, and is particularly suitable for use in laser processing machines such as engraving or cutting. [Background technology]
[0002] Generally, the basic principle of a laser processing machine that can perform tasks such as engraving or cutting is to guide a laser output beam to align it with the surface of the object to be engraved. After the aligned beam is absorbed by the material, the temperature rises sharply, causing the surface of the workpiece to become depressed, thereby achieving the purpose of engraving or cutting.
[0003] With the widespread availability of high-quality laser processing machines, various laser processing machines have been developed that are specialized for leather, cloth, acrylic, etc., due to the fast and easy cutting. Regarding the removal of heat and chips generated during laser processing, the machines are designed to immediately remove the high temperature, smock, and chips generated on the workpiece during laser processing. Summary of the Invention [Problem to be solved by the invention]
[0004] Regarding smoke, the smoke generated during processing can easily cause workpieces such as acrylic to atomize, significantly affecting their appearance. Current solutions involve adding exhaust equipment or slowing down the processing speed, thereby extending the time the smoke adheres to the acrylic. However, adding an exhaust equipment increases the cost of the machine, and slow processing speeds increase the working time, resulting in reduced production efficiency.
[0005] SUMMARY OF THE INVENTION A primary object of the present invention is to provide a smock removal nozzle structure for a laser processing machine that is simple in structure and low in cost. [Means for solving the problem]
[0006] In order to achieve the above object, the smock removal nozzle structure for a laser processing machine according to the present invention includes a main body, the main body is connected to the bottom of a laser output device of the laser processing machine, and moves to the work table of the laser processing machine in response to the laser output device, a through hole is provided in the center position through which the laser of the laser processing machine outputs, a channel is formed around the through hole, and the front and rear ends of the channel penetrate the outer wall surface of the main body.
[0007] In implementation, the front end of the channel is connected to a blower device, and the rear end of the channel penetrates the bottom of the main body, so that the gas emitted from the blower device is emitted from the rear end of the channel to disperse smock that has accumulated or remained on the workpiece to be processed on the workbench.
[0008] In implementation, the front end of the channel communicates with the bleed device, and the rear end of the channel penetrates the bottom of the main body, so that when the bleed device bleeds air, smock accumulated or remaining on the workpiece to be processed on the workbench is sucked in from the rear end of the channel.
[0009] In implementation, the rear end of the channel penetrates the outer wall surface of the main body so as to incline upward, and the front end of the channel communicates with a blower. When the blower blows air, an airflow is ejected from the rear end of the channel, and the flow rate of this airflow increases after passing through the channel, thereby reducing the ambient air pressure around the nozzle and creating a pressure difference with the area directly below the nozzle, forcing smoke and dust from the workpiece to be guided to the surroundings.
[0010] In implementation, the rear end of the channel penetrates the outer wall surface of the main body so as to slope upward, and another channel is joined to the channel, one end of the channel is connected to the channel, the other end penetrates the bottom of the main body, and the front end of the channel is connected to a blower device, and when the blower device blows air, smock accumulated or remaining on the workpiece to be processed on the workbench enters the channel due to the Venturi effect and is blown out from the rear end of the channel.
[0011] In an implementation, the wall of the channel is a wall having a helical surface.
[0012] In the implementation, the wall surface of the through hole is a wall surface having a spiral surface.
[0013] In the implementation, the wall surfaces of the channel and the through-hole are all wall surfaces having a spiral surface.
[0014] In implementation, the through-hole communicates with a ventilation hole for communication with a blower. [Effects of the Invention]
[0015] The design of the present invention provides the following advantages: 1. In the present invention, the nozzle is designed with a through hole and a channel, so that the channel around the through hole for the laser output, whether it is connected to a blower or an extractor, disperses smock that has accumulated or remained on the workpiece around or at the bottom of the body. 2. The nozzle design of the present invention provides a spiral surface on either or both of the channel and through-hole, which when connected to a blower will generate a spiral airflow that will be expelled outward, helping to break up and disperse accumulated smock. 3. The nozzle of the present invention may be configured to penetrate the outer wall surface of the body so that the rear end of the channel is inclined upward, and when coupled with a design in which another channel is joined to the channel, when the blower blows air, smock accumulated or remaining on the workpiece is accelerated by the negative pressure, enters the channel, and is sprayed out from the rear end of the channel. 4. The nozzle according to the present invention has a simple structure, is easy to assemble, and is low in cost. The laser output device can be used as both an air blower and an air extraction device, and can be attached to a laser output device (e.g., a laser pointer) without modifying the structure of a conventional laser output device.

[0017] 1 to 7, an embodiment of a smock removal nozzle structure for a laser processing machine according to the present invention is illustrated.
[0018] As shown in FIG. 1, the smock removal nozzle structure for a laser processing machine according to the present invention includes a main body 1, which is coupled to the bottom of a laser output device 21 of a laser processing machine 2, and the laser processing machine 2 is provided with a work table 22 on which a workpiece 3 is placed and processed, while the main body 1 moves to the work table 22 of the laser processing machine 2 in response to the laser output device 21.
[0019] As shown in Figures 2 and 3, a through hole 11 is provided in the center of the main body 1 for the laser of the laser processing machine 2 to output, so that when the laser from the laser processing machine 2 is output from the through hole 11 of the main body 1, it can engrave or cut the workpiece 3 placed on the workbench 22, and in the main body 1, a channel 12 is formed around the through hole 11, and the front end 121 and rear end 122 of the channel 12 penetrate the outer wall surface 10 of the main body 1.
[0020] In terms of design, the front end 121 of the channel 12 penetrates the outer wall surface 10 at the top of the main body 1, and the rear end 122 of the channel 12 penetrates the outer wall surface 10 at the bottom of the main body 1 (see FIGS. 2 and 3), so that the front end 121 of the channel 12 communicates with a blower, and gas blown out from the blower is blown out from the rear end 122 of the channel 12, thereby dispersing smock accumulated or remaining on the workpiece 3. Of course, in terms of use, the front end 121 of the channel 12 communicates with an air extraction device, so that when the air extraction device extracts air, smock accumulated or remaining on the workpiece 3 is sucked in from the rear end 122 of the channel 12.
[0021] 4 and 5, the rear end 122 of the channel 12 penetrates the outer wall surface 10 of the main body 1 so as to be inclined upward. When the front end 121 of the channel 12 is connected to an air blowing device, after the air blowing device blows air, the airflow emitted from the rear end 122 of the channel 12 flows at high speed around the main body 1, and smock accumulated or remaining on the workpiece 3 around the main body 1 or at the bottom of the main body 1 is guided away from the workpiece 3 by the pressure difference caused by the high-speed airflow.
[0022] On the other hand, with regard to the design in which "the rear end 122 of the channel 12 is inclined upward relative to the outer wall surface 10 of the main body 1," another channel 13 may be joined to the channel 12 (see FIG. 6). One end of the channel 13 communicates with the channel 12, and the other end penetrates the bottom of the main body 1. If the front end 121 of the channel 12 communicates with a blower, when the blower blows air, smock accumulated or remaining on the workpiece 3 enters the channel 13 by the Venturi effect and is blown out from the rear end 122 of the channel 12.
[0023] In each of the above-described embodiments, the through-hole 11 may be connected to a ventilation hole 14 that is connected to the above-described blower (see FIGS. 2 and 3). This increases the probability of dispersing smock that has accumulated or remained on the workpiece 3. As a further effect, the wall surface of the channel 12 of the main body 1, the wall surface of the through-hole 11, or the wall surfaces of both the channel 12 and the through-hole 11 may be configured as a wall surface having a spiral surface 15 (see FIGS. 7 to 11). Thus, when these are connected to a blower, gas blown out from the blower can be blown out by generating a spiral airflow through the wall surface of the spiral surface 15.

Many changes and modifications can be derived based on the disclosure or teachings of the present invention, but they can still be considered as equivalent modifications according to the concept of the present invention, and the actions they produce still do not go beyond the substantial spirit contained in the specification and drawings, and all should be considered to be within the technical scope of the present invention.
