Description

Technical Field

[0001] This utility model relates to the field of profile cutting, specifically a dust removal mechanism for profile cutting. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Aluminum profiles are commonly used in automated equipment and doors and windows. Since the length and angle of these profiles need to be customized, profile cutting equipment is required to cut them to the correct dimensions. During the cutting process, sawdust flies everywhere. If this sawdust is not cleaned up promptly, it can scratch the outer surface of the profile as it moves, affecting its appearance and the cutting effect. Currently, many existing profile cutting devices have a semi-recessed saw blade design, with half of the saw blade resting on the worktable surface, usually inside or below it. This means that when sawdust flies, it not only lands on the worktable surface but also enters the worktable as the blade rotates. Over time, this will inevitably affect the blade's movement. Therefore, a dust removal mechanism for profile cutting is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal mechanism for profile cutting. It can timely adsorb sawdust through negative pressure during the profile cutting process, thereby preventing sawdust from splashing everywhere and scratching the profile surface, as well as from entering the components that drive the displacement and rotation of the saw blade, thus affecting the cutting accuracy of the saw blade.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A dust removal mechanism for profile cutting includes a cover and a base plate disposed below the cover. The bottom surface of the cover is funnel-shaped, and a worktable is provided above the cover with a movable opening. A discharge port is provided below the base plate and is connected to the cover. A negative pressure component is connected to the discharge port, which generates negative pressure and adsorbs sawdust through the movable opening, and discharges it through the discharge port below the cover.

[0007] The dust removal mechanism also includes an air storage tank, a booster pump, and multiple air knives connected to the booster pump; the air knives are installed inside the hood and are used to blow sawdust from inside the hood into the movable opening.

[0008] The negative pressure component is a vacuum pump.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] It can use negative pressure to adsorb sawdust in a timely manner during the profile cutting process, thereby preventing sawdust from splashing everywhere and scratching the profile surface, as well as from entering the components that drive the displacement and rotation of the saw blade, thus affecting the cutting accuracy of the saw blade.

[0015] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0016] This utility model describes a dust removal mechanism for profile cutting, as shown in the attached drawings. Figure 1 and Figure 2 As shown, the main structure includes a cover 1 and a base plate 2 located below the cover 1;

[0017] A workbench 3 is provided above the cover 1. The workbench 3 is used to place and cut profiles with a saw blade. The workbench 3 has a movable opening 4, within which the saw blade moves. A discharge port 5 is provided below the base plate 2. The discharge port 5 is connected to the cover 1. A negative pressure component, which is a vacuum pump, is connected to the discharge port 5 via a pipeline. The negative pressure component generates negative pressure and adsorbs sawdust through the movable opening 4, which is then discharged through the discharge port 5 below the cover 1. Since the cover 1 is in a closed state, the negative pressure airflow generated by the vacuum pump adsorbs sawdust near the movable opening 4 and sawdust on the saw blade during profile cutting. To avoid sawdust residue inside the cover 1, the cover 1 is further improved by having a funnel-shaped bottom surface. The dust removal mechanism also includes an air tank, a booster pump, and multiple air knives 6 connected to the booster pump.

[0018] The air knife 6 is set on the funnel-shaped bottom surface inside the cover 1. After the sawdust falls into the cover 1 from the movable port 4, the airflow generated by the booster pump enters the air knife 6 and is blown out by the air knife 6. The air knife 6 is mostly used for blowing chips and other purposes. It has strong airflow. The air knife 6 blows the sawdust towards the center of the cover 1, where it is absorbed and discharged by the negative pressure airflow generated by the vacuum pump through the movable port 4.

[0019] In the case of the profile cutting device applied in this application, the saw blade of the profile cutting device is set inside the cover 1, and a steering drive is provided on the outside of the cover 1. The steering drive at the bottom of the cover 1 is a central control turntable. By using a worm gear mechanism to drive the cover 1 to rotate, the cutting direction of the saw blade of the cutting mechanism on the worktable 3 is changed. In this application, it is not affected by the cutting angle of the saw blade, but rotates together with the saw blade, and can timely absorb the sawdust generated by cutting the profile.

[0020] Detailed instructions for use:

[0021] When the saw blade is cutting the profile, the negative pressure generated by the vacuum pump adsorbs the sawdust produced during the cutting process. After the profile is cut, the airflow generated by the booster pump is blown into the inside of the cover 1 by the air knife 6, and the vacuum pump adsorbs and discharges the sawdust inside the cover 1.

[0022] In summary, this device can use negative pressure to promptly absorb sawdust during the profile cutting process, thereby preventing sawdust from splashing everywhere and scratching the profile surface, as well as from entering the components that drive the displacement and rotation of the saw blade, thus affecting the cutting accuracy of the saw blade.
