Description

Technical Field

[0001] The invention relates to the technical field of cutting protection devices, and in particular to dust adsorption equipment. Background Art

[0002] A circular saw refers to a toothed tool used to cut aluminum. A circular saw for aluminum alloy plates will generate a large amount of aluminum chips and aluminum dust when working. If the aluminum dust generated by sawing is not collected and treated or the treatment effect is not good, it will cause great harm to the human body and the environment. The current traditional method is to collect dust through a dust suction fan and a dust suction pipeline. Since the circular saw needs to rotate 90 degrees to change the cutting direction during operation, the dust suction pipeline is usually connected with a flexible hose. However, as the circular saw rotates, the hose will move, and friction will occur between the hose and other components. This causes the hose to be easily damaged after being used for a period of time. After the hose is damaged, the dust suction effect is poor and maintenance and replacement are required, which seriously affects production efficiency. Therefore, how to provide a dust suction device whose dust suction pipeline is not easy to be damaged and can ensure dust suction effect and production efficiency is an urgent problem to be solved by technicians in this field.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The core purpose of the present invention is to provide a dust suction device to solve the problem that the dust suction pipeline is easily damaged by friction when connected through a hose, thereby ensuring the dust suction effect and production efficiency. Figure 6The dust adsorption device provided by the present invention includes an equipment body 10, a connecting head 11, a connecting assembly, an adsorption box 30 and a circular saw blade cover 50; the equipment body 10 is fixedly arranged, the connecting head 11 is arranged on the equipment body 10, and is located at the bottom of the equipment body 10, and the connecting head 11 is used to rotate and lift relative to the equipment body 10; the connecting assembly is arranged on the equipment body 10, and the connecting assembly includes a fixed pipeline 20 and a movable joint 21, the fixed pipeline 20 is fixedly arranged on the equipment body 10, and the movable joint 21 is movably arranged on the fixed pipeline 20; the adsorption box 30 is fixedly arranged on the connecting head 11, and is used to absorb dust generated during cutting. The adsorption box 30 is provided with two discharge ports 31, one of which is closed, and the other is connected to the fixed pipeline 20 through the movable joint 21; the circular saw blade cover 50 is arranged on the connecting head 11, and the circular saw blade cover 50 includes a dust collecting chamber 53, and the dust collecting chamber 53 is connected to the adsorption box 30.

[0043] During operation, one of the discharge ports 31 of the adsorption box 30 is closed, and the other discharge port 31 of the adsorption box 30 is connected to the fixed pipeline 20 through the movable joint 21, and the dust suction pipeline is connected; when it is necessary to rotate 90° to change the cutting direction, the connecting head 11 rotates 90°, and the rotation of the connecting head 11 drives the adsorption box 30 to rotate 90°. After the adsorption box 30 rotates 90°, the discharge port 31 previously connected to the fixed pipeline 20 through the movable joint 21 is closed, and as the movable joint 21 moves, the previously closed discharge port 31 is connected to the fixed pipeline 20 through the movable joint 21, and the dust suction pipeline is connected.

[0044] With such arrangement, after rotating 90° to change the cutting direction, by moving the movable joint 21, one of the discharge ports 31 of the adsorption box 30 is connected to the fixed pipeline 20 through the movable joint 21, and the dust suction pipeline is in a connected state. Even if it is used for a long time and the cutting direction is changed frequently, the dust suction pipeline formed by the adsorption box 30 and the fixed pipeline 20 is not easily damaged, thereby ensuring the dust suction effect and production efficiency.

[0045] Please refer to Figures 1, 2, 3 and 5 together. The fixed pipeline 20 is vertically arranged, and the movable joint 21 is arranged at the lower end of the fixed pipeline 20.

The fixed pipeline 20 is installed on the equipment body 10 through the pipe clamp, and the connection is reliable and easy to assemble and disassemble. The fixed pipeline 20 and the first hose 201 are connected through the throat clamp to ensure a tight connection and avoid leakage.

[0047] Please refer to Figures 1, 2, 3 and 5 together. In the dust adsorption equipment provided by the present invention, the connecting assembly also includes a bracket 22, a telescopic device 23 and a connecting piece 24; the bracket 22 is fixedly arranged on the equipment body 10; the telescopic device 23 is fixedly arranged on the bracket 22, and is used to drive the movable joint 21 to slide along the fixed pipeline 20; the connecting piece 24 is rotatably arranged on the bracket 22, the connecting piece 24 is connected to the telescopic end of the telescopic device 23, and the connecting piece 24 is hinged to the movable joint 21.

[0048] The bracket 22 is generally L-shaped, the fixed end of the telescopic device 23 is hinged to the bracket 22, and the other end of the telescopic device 23 is hinged to the connecting piece 24. As the telescopic device 23 is extended and retracted, the movable joint 21 is driven to slide along the fixed pipeline 20, so that the discharge port 31 of the adsorption box 30 can be connected to the fixed pipeline 20 through the movable joint 21. In this embodiment, the telescopic device 23 adopts a cylinder, and in other embodiments, the telescopic device 23 can also adopt an electric cylinder or a hydraulic cylinder, etc., which is not specifically limited.

[0049] Please refer to Figure 5, the connecting member 24 includes a first connecting portion 241 and a second connecting portion 242, the first connecting portion 241 is connected to the second connecting portion 242, one end of the first connecting portion 241 away from the second connecting portion 242 is hinged to the telescopic end of the telescopic device 23, and the second connecting portion 242 is hinged to the movable joint 21.

[0050] The first connection part 241 is a straight rod, and the second connection part 242 is a U-shaped rod. One end of the first connection part 241 is hinged to the telescopic end of the telescopic device 23, and the other end of the first connection part 241 is connected to the middle part of the second connection part 242. The two ends of the second connection part 242 are respectively hinged to the two sides of the movable joint 21. With this arrangement, the movement of the movable joint 21 along the fixed pipeline 20 is smoother.

[0051] 5 , two hinged arms 25 are provided on both sides of the movable joint 21, and the two ends of the hinged arms 25 are respectively hinged to the movable joint 21 and the second connection portion 242 of the connecting member 24. The connecting member 24 is hinged to the movable joint 21 through the two hinged arms 25, so as to realize the connection between the connecting member 24 and the two sides of the movable joint 21.

[0052] Please refer to Figure 5. A hinge seat 26 is fixedly provided on the bracket 22. The first connecting portion 241 of the connecting member 24 is hinged to the bracket 22 through the hinge seat 26. In this way, the connecting member 24 can be rotatably arranged on the bracket 22. As the telescopic device 23 works, the telescopic end of the telescopic device 23 drives the connecting member 24 to rotate. The connecting member 24 drives the movable joint 21 to slide along the fixed pipeline 20 through the hinge arms 25 on both sides of the movable joint 21, so as to connect the adsorption box 30 to the fixed pipeline 20 through the movable joint 21.

[0053] Please refer to Figures 1 to 3 together. The dust adsorption equipment provided by the present invention also includes two sets of sealing components, which are used to seal the discharge port 31 of the adsorption box 30. The two sets of sealing components are arranged on both sides of the equipment body 10. During operation, one of the discharge ports 31 on the adsorption box 30 is connected to the fixed pipeline 20 through the movable joint 21, and the other discharge port 31 on the adsorption box 30 is sealed by the sealing component. When it is necessary to rotate 90° to change the cutting direction, the adsorption box 30 is driven to rotate 90° as the connecting head 11 rotates. After the adsorption box 30 rotates 90°, the discharge port 31 previously connected to the fixed pipeline 20 through the movable joint 21 is closed by another set of sealing components. As the movable joint 21 moves, the previously closed discharge port 31 is connected to the fixed pipeline 20 through the movable joint 21, and the dust collection pipeline is connected.

[0054] Please refer to Figures 1, 2, 3 and Figure 6 The sealing assembly includes a fixed plate 40, a support arm 41 and a pressure cover 42; the fixed plate 40 is fixed to the bracket 22; the support arm 41 is fixed to the fixed plate 40, and the support arm 41 is arranged horizontally; the pressure cover 42 is rotatably connected to the end of the support arm 41 away from the fixed plate 40 through the connecting arm 43. When working, the pressure cover 42 is located directly above the discharge port 31 of the adsorption box 30, and the bottom of the pressure cover 42 closes the discharge port 31 by its own weight, which is convenient to use.

[0055] Please refer to Figure 6 The support arm 41 is fixed with a mounting plate 411, and the mounting plate 411 is fixedly connected with a vertically arranged bolt 412, and the top end of the bolt 412 abuts against the connecting arm 43 to make the pressure cover 42 in a horizontal state. Through such a setting, the pressure cover 42 can fit tightly with the discharge port 31 on the adsorption box 30, thereby ensuring the sealing effect between the pressure cover 42 and the discharge port 31.

[0056] Please refer to Figure 6 The bottom of the pressure cover 42 has a taper. For example, a 15° taper is set at the bottom of the pressure cover 42. By setting the taper, when the bottom of the pressure cover 42 closes the discharge port 31, the bottom of the pressure cover 42 can partially enter the discharge port 31, thereby increasing the contact area between the two and further ensuring the sealing effect.

[0057] Please refer to FIG. 1 to FIG. 3 . In the dust adsorption device provided by the present invention, the circular saw blade cover 50 is arranged outside the saw blade 60 , and the saw blade 60 is driven to rotate by the driving motor.
