Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to an automatic waste cleaning device for laser cutting machines. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece. Laser cutting is one of the thermal cutting methods.

[0003] An existing waste cleaning device for laser cutting machines (publication number: CN212286353U) has at least the following drawbacks: Although the device can push the waste from the box to the trash can through the pusher block, in actual operation, the molten waste often falls directly onto the pusher block when it falls into the box. Because the waste is at a high temperature and in a semi-molten state, it is easy to stick to the surface of the pusher block, which hinders the movement of the pusher block and affects the smooth cleaning of the waste and the normal operation of the device. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic waste cleaning device for laser cutting machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic waste cleaning device for laser cutting machines includes a cutting machine body. The bottom surface of the cutting machine body is provided with a cleaning structure. The cleaning structure includes a collection box fixed to the bottom surface of the cutting machine body. A movable plate is slidably arranged inside the bottom surface of the collection box. The top surface of the movable plate is inclined. An installation groove is opened on one side of the inner wall of the collection box. The movable plate is slidably arranged inside the installation groove. A cam is rotatably arranged inside the installation groove. The outer circular wall surface of the cam is in contact with one side of the movable plate. Two tension springs are fixed inside the installation groove. One end of the tension spring is fixed to one side of the movable plate.

[0007] As a further embodiment of this utility model, a motor is fixed to the bottom surface of the collection box, the output end of the motor passes through the bottom surface of the collection box and is fixed to the cam, a fixing groove is opened on one side of the inner wall of the collection box, a connecting pipe is fixed to the inner wall of the fixing groove, and several spray holes are opened on one side of the connecting pipe. A fan is fixed to the bottom surface of the cutting machine body, and the fan is connected to the connecting pipe.

[0008] As a further embodiment of this utility model, one side of the collection box is open, and a movable compartment is slidably provided on the open side of the collection box. A fixed sleeve is fixed on the bottom surface of the collection box, and an electric push rod is fixed inside the fixed sleeve. The telescopic end of the electric push rod is rotatably arranged with one side of the movable compartment. One side of the movable compartment is open, and a cover plate is rotatably provided on the open side of the movable compartment.

[0009] As a further embodiment of this utility model, a limiting rod is fixed to one side of the fixed sleeve, and the limiting rod is slidably disposed with one side of the movable compartment.

[0010] As a further embodiment of this utility model, a rotating groove is provided on one side of the movable compartment, and an annular groove is provided on the inner wall of the rotating groove. An anti-detachment ring is fixed to the telescopic end of the electric push rod, and the anti-detachment ring is rotatably arranged with the inside of the annular groove.

[0011] As a further embodiment of this invention, the inner wall of the collection box and the top surface of the movable plate are both coated with a Teflon coating.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This automatic cleaning device, through its cleaning structure, allows operators to start a motor that drives a cam to rotate. During rotation, the cam periodically pushes a movable plate, causing it to vibrate continuously under the elastic force of a tension spring. This prevents waste from adhering to the surface of the movable plate and encourages it to slide down to the bottom of the plate. A fan delivers airflow into the collection box through connecting pipes and several nozzles. The airflow generated by the fan not only accelerates the cooling and solidification of the waste but also blows lightweight waste or dust away from the surface of the movable plate, further reducing the risk of adhesion and ensuring smooth waste removal and normal operation of the device.

[0023] Reference Figures 1-5 An automatic waste cleaning device for laser cutting machines includes a cutting machine body 1. The bottom surface of the cutting machine body 1 is provided with a cleaning structure, which includes a collection box 2 fixed to the bottom surface of the cutting machine body 1. A movable plate 201 is slidably arranged on the bottom surface of the collection box 2. The top surface of the movable plate 201 is an inclined surface. An installation groove 202 is opened on one side of the inner wall of the collection box 2. The movable plate 201 is slidably arranged inside the installation groove 202. A cam 203 is rotatably arranged inside the installation groove 202. The outer circular wall surface of the cam 203 is in contact with one side of the movable plate 201. Two tension springs 204 are fixed inside the installation groove 202. One end of the tension spring 204 is fixed to one side of the movable plate 201. The cutting machine body 1 is a laser cutting machine.

[0024] In this embodiment, a motor is fixed to the bottom surface of the collection box 2. The output end of the motor passes through the bottom surface of the collection box 2 and is fixed to the cam 203. A fixing groove 3 is provided on one side of the inner wall of the collection box 2. A connecting pipe 301 is fixed to the inner wall of the fixing groove 3. Several spray holes 302 are provided on one side of the connecting pipe 301. A fan 303 is fixed to the bottom surface of the cutting machine body 1. The fan 303 is connected to the connecting pipe 301. Through the setting of the cleaning structure, the operator starts the motor to drive the cam 203 to rotate. During the rotation, the cam 203 periodically pushes the movable plate 201, so that the movable plate 201 moves... The tension spring 204 generates continuous vibration under its elastic force. This vibration can effectively prevent waste from adhering to the surface of the movable plate 201 and cause the waste to slide down to the bottom of the movable plate 201. At the same time, the operator starts the blower 303 and delivers airflow into the collection box 2 through the connecting pipe 301 and several nozzles 302. When the molten waste falls into the collection box 2, the airflow generated by the blower 303 can not only accelerate the cooling and solidification of the waste, but also blow light waste or dust away from the surface of the movable plate 201, further reducing the risk of adhesion, thereby ensuring the smooth cleaning of waste and the normal operation of the device.

[0025] In this embodiment, one side of the collection box 2 is open, and a movable chamber 205 is slidably disposed on the open side of the collection box 2. A fixing sleeve 206 is fixed to the bottom surface of the collection box 2, and an electric push rod 207 is fixed inside the fixing sleeve 206. The telescopic end of the electric push rod 207 is rotatably disposed with one side of the movable chamber 205. One side of the movable chamber 205 is open, and a cover plate 208 is rotatably disposed on the open side of the movable chamber 205. When the waste accumulates to a certain height at the inclined bottom of the movable plate 201, the operator starts the electric push rod 207 to push the movable chamber 205 away from the open side of the collection box 2. At the same time, the vibration of the movable plate 201 pushes the waste in the collection box 2 into the movable chamber 205. After the waste enters the movable chamber 205, the operator rotates the movable chamber 205 to pour the waste out of the movable chamber 205, which facilitates the operator to collect and process the waste.

[0026] In this embodiment, a limiting rod 4 is fixed to one side of the fixed sleeve 206. The limiting rod 4 is slidably disposed with one side of the movable chamber 205. When the electric push rod 207 pushes the movable chamber 205 away from the open side of the collection box 2, the limiting rod 4 slides inside the movable chamber 205 to prevent the movable chamber 205 from rotating. When the waste falls into the movable chamber 205, the electric push rod 207 continues to push the movable chamber 205, causing the limiting rod 4 to disengage from the movable chamber 205 and cancel the limiting, allowing the staff to rotate the movable chamber 205 to dump and collect the waste.

[0027] In this embodiment, a rotating groove 5 is provided on one side of the movable chamber 205, and an annular groove 501 is provided on the inner wall of the rotating groove 5. An anti-detachment ring 502 is fixed to the telescopic end of the electric push rod 207, and the anti-detachment ring 502 is rotatably arranged with the annular groove 501.

[0028] In this embodiment, the inner wall of the collection box 2 and the top surface of the movable plate 201 are coated with Teflon coating. Teflon coating is a prior art technology and has a good anti-stick effect at high temperatures.

[0029] Working Principle: During operation, the cutting machine body 1 performs a cutting operation. The workpiece waste generated by laser cutting is discharged from the gap on the table of the cutting machine body 1 into the collection box 2. The operator starts the motor to drive the cam 203 to rotate. During the rotation, the cam 203 periodically pushes the movable plate 201, causing the movable plate 201 to vibrate continuously under the elastic force of the tension spring 204. This vibration can effectively prevent the waste from adhering to the surface of the movable plate 201 and cause the waste to slide down to the bottom of the movable plate 201. At the same time, the operator starts the fan 303, which delivers airflow into the collection box 2 through the connecting pipe 301 and several nozzles 302. When the molten waste falls into the collection box 2, the airflow generated by the fan 303 can not only accelerate the cooling and solidification of the waste, but also... The vibration of the movable plate 201 can also blow lightweight waste or dust away from the surface of the movable plate 201, further reducing the risk of adhesion. When the waste accumulates to a certain height at the inclined bottom of the movable plate 201, the staff will activate the electric push rod 207 to push the movable chamber 205 away from the open side of the collection box 2. At the same time, the vibration of the movable plate 201 will push the waste in the collection box 2 into the movable chamber 205. After the waste enters the movable chamber 205, the staff will rotate the movable chamber 205 to pour the waste out of the movable chamber 205, making it easier for the staff to collect and process the waste. When the waste falls into the movable chamber 205, the electric push rod 207 will continue to push the movable chamber 205, causing the limit rod 4 to disengage from the movable chamber 205 and cancel the limit, allowing the staff to rotate the movable chamber 205 to dump and collect the waste.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
