Description

Technical Field

[0001] The invention relates to the field of door and window profile processing, and in particular to a door and window profile laser cutting device. Background Art

[0002] Door and window profiles are components of existing doors and windows. They are generally existing steel components. During their processing, laser cutting machines are used to cut them. In order to ensure the safety of cutting, some laser cutting machines now carry out the entire cutting process in a relatively sealed environment.

[0003] During the cutting process, a large amount of cutting smoke will be generated. These cutting smoke have a strong odor and are harmful to the human body. In order to solve this problem, the prior art generally uses a suction fan in combination with activated carbon to treat the cutting smoke. However, in actual use, we found that the existing cutting smoke has a high temperature, and the activated carbon has a poor treatment effect on high-temperature smoke, resulting in poor actual smoke treatment effect. In addition, in order to facilitate the movement of existing cutting equipment, a plurality of moving wheels are generally provided at the lower end, which will lead to poor stability of the cutting equipment during use. Therefore, how to solve this problem is what we need to consider. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a laser cutting device for door and window profiles is proposed. During the use of the device, the stability of the device during use can be guaranteed on the basis of the movement of the device. In addition, a low-temperature blowing structure is also provided to allow the cutting smoke to reduce the temperature before contacting with activated carbon, thereby improving the adsorption effect of activated carbon on the smoke.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A laser cutting device for door and window profiles comprises a shell, a cutting chamber is arranged in the shell, a placing rack is installed at the inner bottom of the cutting chamber, and a cutting assembly is installed at the inner top of the cutting chamber; a cooling and deodorizing mechanism, the cooling mechanism comprises a high-pressure air pump installed on the left side of the shell, the air outlet end of the high-pressure air pump is connected with a vortex tube, the cold air end of the vortex tube is connected with a second branch pipe, a second one-way valve is installed in the second branch pipe, a hollow plate is installed on the left inner wall of the cutting chamber, a plurality of diversion ports are opened on the right side wall of the hollow plate, a filter box is installed on the right side of the shell, the inner top space of the filter box is connected with the inside of the cutting chamber through a connecting pipe, activated carbon is installed in the filter box, and an exhaust port is opened at the inner bottom of the filter box; a movable supporting mechanism, the movable supporting mechanism is located below the shell; a deodorizing mechanism, the deodorizing mechanism is used to remove cutting odor.

[0007] Preferably, a first sealing door is installed on the front side of the shell, and a second sealing door is installed on the front side of the filter box.

[0008] Preferably, the mobile support mechanism comprises a roller mounted on the lower end of the shell, and a slide groove is provided on the lower end of the shell.

[0009] Preferably, two electric telescopic rods are installed on the inner top of the slide slot, and the telescopic ends of the two electric telescopic rods are commonly fixedly connected with a damping plate, and the lower end of the damping plate is provided with a rubber layer.

[0010] Preferably, the deodorizing mechanism includes an air storage chamber and a liquid storage chamber opened in the shell, the liquid storage chamber is filled with deodorant, a plurality of sponge strips are vertically arranged in the liquid storage chamber, the upper ends of the plurality of sponge strips extend into the air storage chamber, a liquid filling port is opened in the right space of the air storage chamber, and a sealing plug is installed on the right side of the liquid filling port.

[0011] Preferably, the hot air end of the vortex tube is connected to a first branch pipe, a first one-way valve is installed inside the first branch pipe, the other end of the first branch pipe extends into the air storage chamber, the right side space of the air storage chamber is connected to the interior of the hollow plate through a release pipe, a normally open solenoid valve is installed in the release pipe, and the normally open solenoid valve and the high-pressure air pump are in the same series circuit.

[0012] Preferably, the hot air end of the vortex tube is connected to a first branch pipe, a first one-way valve is installed inside the first branch pipe, the other end of the first branch pipe extends into the air storage chamber, the right side space of the air storage chamber is connected to the interior of the hollow plate through a release pipe, a normally open solenoid valve is installed in the release pipe, and the normally open solenoid valve and the high-pressure air pump are in the same series circuit.

The low-temperature airflow cools down the high-temperature flue gas, which can effectively improve the adsorption effect of the activated carbon on the flue gas, thereby improving the flue gas purification effect.

[0017] 3. The high-temperature airflow discharged from the vortex tube will be stored. The stored high-temperature airflow will accelerate the volatilization of the deodorant. After the high-pressure air pump is turned off, the gas carrying the deodorant molecules is pressed into the hollow plate and finally enters the cutting chamber to absorb and cover up the residual cutting odor, thereby preventing the residual cutting odor in the subsequent cutting chamber from affecting the staff.

[0018] In summary, the equipment has strong stability during cutting while ensuring mobility. In addition, the combination of vortex tube and high-pressure air pump not only improves the adsorption effect of smoke, but also performs a deodorization treatment after cutting, effectively avoiding the impact of smoke odor on workers.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Reference Figure 1-5 A laser cutting device for door and window profiles includes a housing 1, a cutting chamber 2 is arranged in the housing 1, a placing frame 9 is installed at the inner bottom of the cutting chamber 2, a cutting assembly 10 is installed at the inner top of the cutting chamber 2, the cutting assembly 10 is a prior art, which is composed of a moving part and a cutting head, and the cutting head is moved by the moving part to achieve cutting, a first sealing door 32 is installed at the front side of the housing 1, and the first sealing door 32 facilitates the purpose of taking out and putting in the workpiece, and a second sealing door 20 is installed at the front side of the filter box 23, and the second sealing door 20 realizes the function of replacing the activated carbon 25;

[0028] As an embodiment of the present invention, it also includes a cooling and deodorizing mechanism. The cooling mechanism includes a high-pressure air pump 11 installed on the left side of the shell 1. When the high-pressure air pump 11 is in use, a high-speed airflow will be generated at its outlet. The outlet of the high-pressure air pump 11 is connected to a vortex tube 27. The vortex tube 27 is a prior art. The gas that has been compressed and cooled to room temperature enters the nozzle, expands and accelerates to the speed of sound in the nozzle, and is injected into the vortex chamber from the tangential direction to form a free vortex. The closer the rotation angular velocity of the free vortex is to the center, the greater it is. Due to the different angular velocities, friction is generated between the layers of the free vortex. The angular velocity of the airflow in the center is the largest. As a result of the friction, energy is transferred to the airflow in the outer layer with a lower angular velocity. The airflow in the center layer loses energy, has low kinetic energy, and has a reduced speed. The temperature is lowered and the air is led out from one end through the orifice plate in the center of the vortex tube to obtain the cold air flow required for refrigeration, while the air flow in the outer layer gains momentum and increases its kinetic energy. At the same time, it rubs against the turbine tube wall to convert part of the kinetic energy into heat energy, which is led out from the other end of the vortex tube through the control valve to form a hot air flow. The cold air end of the vortex tube 27 is connected with a second branch pipe 28, and a second one-way valve 29 is installed in the second branch pipe 28. A hollow plate 30 is installed on the left inner wall of the cutting chamber 2, and a plurality of diversion ports 31 are provided on the right side wall of the hollow plate 30. A filter box 23 is installed on the right side of the housing 1, and the inner top space of the filter box 23 is connected with the inside of the cutting chamber 2 through a connecting pipe 24. Activated carbon 25 is installed in the filter box 23, and an exhaust port 26 is provided at the inner bottom of the filter box 23.

[0029] As an embodiment of the present invention, it also includes a mobile support mechanism, which is located below the housing 1. The mobile support mechanism includes a roller 5 installed at the lower end of the housing 1. A slide groove 6 is provided at the lower end of the housing 1. Two electric telescopic rods 7 are installed at the inner top of the slide groove 6. The telescopic ends of the two electric telescopic rods 7 are fixedly connected with a damping plate 8. A rubber layer is provided at the lower end of the damping plate 8. When in use, the device can be moved by the roller 5. When the device needs to be stable, the electric telescopic rod 7 only needs to be started to move the damping plate 8 downward to contact the ground to achieve support.

[0030] As an embodiment of the present invention, it also includes a deodorizing mechanism, which is used to remove the cutting odor. The deodorizing mechanism includes an air storage chamber 4 and a liquid storage chamber 3 provided in the shell 1. The liquid storage chamber 3 is filled with a deodorant, which is a deodorizing liquid with a volatile effect. A plurality of sponge strips 14 are vertically arranged in the liquid storage chamber 3. The upper ends of the plurality of sponge strips 14 extend into the air storage chamber 4. A liquid filling port 19 is provided in the right space of the air storage chamber 4. A sealing plug is installed on the right side of the liquid filling port 19. The hot air end of the vortex tube 27 is connected with a first branch pipe 12. A first one-way valve 13 is installed in the first branch pipe 12. The other end of the first branch pipe 12 extends into the air storage chamber 4. The right space of the air storage chamber 4 is connected with the inside of the hollow plate 30 through a release pipe 21. A normally open solenoid valve 22 is installed in the release pipe 21. The normally open solenoid valve 22 and the high-pressure air pump 11 are in the same series circuit.

[0031] As an embodiment of the present invention, a piston cylinder 15 is installed at the upper end of the shell 1, and a piston plate 16 that can slide up and down is arranged in the piston cylinder 15. The inner bottom of the piston cylinder 15 is connected with the air storage chamber 4, and the upper end of the piston plate 16 is elastically connected to the inner top of the piston cylinder 15 through a spring 17. A connecting port 18 is opened at the inner top of the piston cylinder 15. The first one-way valve 13 of the first branch pipe 12 flows in the reverse direction so that the cold air end of the vortex tube 27 enters the air storage chamber 4 in one direction, and the second one-way valve 29 of the second branch pipe 28 flows in the direction so that the hot air end of the vortex tube 27 enters the hollow plate 30 in one direction.

[0032] In the present invention, during specific operation, the device can be moved by the roller 5. When the device is moved to a desired position, the electric telescopic rod 7 is started to move the damping plate 8 downward, and finally the lower end surface of the damping plate 8 contacts the ground. In this way, the device can be mobile while ensuring its stability during use.

[0033] The staff opens the first sealing door 32, places the door and window profiles on the placement rack 9, then closes the first sealing door 32, starts the cutting assembly 10 for cutting, and starts the high-pressure air pump 11. After the high-pressure air pump 11 is started, a high-pressure airflow is generated. After the high-pressure airflow passes through the vortex tube 27, the low-temperature airflow generated at the cold end enters the hollow plate 30 through the second branch pipe 28 and is discharged from multiple diversion ports 31. The discharged low-temperature airflow will press the high-temperature flue gas generated by the cutting assembly 10 during cutting into the filter box 23, and finally passes through the activated carbon 25 and is discharged from the exhaust port 26. The low-temperature airflow cools the high-temperature flue gas, which can effectively improve the adsorption effect of the activated carbon 25 on the flue gas, thereby improving the flue gas purification effect;

[0034] In the above process, the hot air discharged from the vortex tube 27 enters the air storage chamber 4 through the first branch pipe 12. Since the normally open solenoid valve 22 is energized and sealed at this time, the gas gathers in the air storage chamber 4 and pushes the piston plate 16 to move upward, compressing the spring 17. In this process, the high-temperature airflow will promote the volatilization of the deodorant on the sponge strip 14, so that the air storage chamber 4 is filled with gas containing deodorant molecules. After the subsequent high-pressure air pump 11 is closed, the normally open solenoid valve 22 is opened. Under the elastic action of the spring 17, the piston plate 16 moves downward and presses the gas containing the deodorant molecules into the hollow plate 30, and finally enters the cutting chamber 2, absorbs and masks the residual cutting odor, and prevents the residual cutting odor in the subsequent cutting chamber 2 from affecting the staff.
