Description

Technical Field

[0001] The utility model relates to the technical field of cutting protection devices, in particular to a dust suction device. Background Art

[0002] A circular saw is 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 during operation. If the aluminum dust generated by sawing is not collected and treated or the treatment effect is poor, 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 pipe. Since the circular saw needs to rotate 90 degrees to change the cutting direction during operation, the dust suction pipe 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 a period of use. After the hose is damaged, the dust suction effect is poor and needs to be maintained and replaced, which seriously affects production efficiency. Therefore, how to provide a dust suction device whose dust suction pipe is not easily damaged and can ensure dust suction effect and production efficiency is a problem that needs to be solved urgently by those skilled in the art.

DETAILED DESCRIPTION

[0032] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] The core purpose of this utility model is to provide a dust collection device that solves the problem that the dust collection pipeline is easily damaged by friction when connected through a hose, ensuring the dust collection effect and production efficiency. Figures 1 to 6 The dust collection device provided by the utility model includes a fixing part 10, a connecting head 11, a connecting assembly and a dust collection box 30; the fixing part 10 is fixedly arranged, the connecting head 11 is arranged on the fixing part 10, and is located at the bottom of the fixing part 10, and the connecting head 11 is constructed to be able to rotate and lift; the connecting assembly is arranged on the fixing part 10, the connecting assembly includes a fixed pipe 20 and a movable joint 21, the fixed pipe 20 is fixedly arranged on the fixing part 10, and the movable joint 21 is movably arranged on the fixed pipe 20; the dust collection box 30 is fixedly arranged on the connecting head 11, and is used to absorb dust generated during cutting. The dust collection box 30 is provided with two discharge ports 31, one of the discharge ports 31 is closed, and the other discharge port 31 is connected to the fixed pipe 20 through the movable joint 21.

[0035] During operation, one of the discharge ports 31 of the dust collection box 30 is closed, and the other discharge port 31 of the dust collection box 30 is connected to the fixed pipe 20 through the movable joint 21, and the dust collection pipe 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 dust collection box 30 to rotate 90°. After the dust collection box 30 rotates 90°, the discharge port 31 previously connected to the fixed pipe 20 through the movable joint 21 is closed. As the movable joint 21 moves, the previously closed discharge port 31 is connected to the fixed pipe 20 through the movable joint 21, and the dust collection pipe is connected.

[0036] With this arrangement, after rotating 90° to change the cutting direction, by moving the movable joint 21, one of the discharge ports 31 of the dust collection box 30 is connected to the fixed pipeline 20 through the movable joint 21, and the dust collection pipeline is in a connected state. Even if it is used for a long time and the cutting direction is changed frequently, the dust collection pipeline formed by the dust collection box 30 and the fixed pipeline 20 is not easily damaged, which can ensure the dust collection effect and production efficiency.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The fixed pipeline 20 is vertically arranged, the movable joint 21 is arranged at the lower end of the fixed pipeline 20, the movable joint 21 is at least partially accommodated in the fixed pipeline 20, and the movable joint 21 is slidably connected to the fixed pipeline 20.

[0038] The fixed pipe 20 is fixedly connected to the fixed component 10 via a pipe clamp. The upper end of the fixed pipe 20 is connected to a first hose 201 via a hose clamp. The upper end of the fixed pipe 20 can be connected to the dust collection fan via the first hose 201. The movable joint 21 is generally tubular and at least partially accommodated within the lower end of the fixed pipe 20. As the movable joint 21 moves, it expands and contracts, thereby connecting the discharge port 31 of the dust collection box 30 to the fixed pipe 20 via the movable joint 21. The fixed pipe 20 is mounted on the fixed component 10 via the pipe clamp, providing a secure connection and easy assembly and disassembly. The hose clamp connection between the fixed pipe 20 and the first hose 201 ensures a tight connection and prevents leakage.

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In the dust collection device provided by the present invention, the connecting assembly also includes a bracket 22, a telescopic device 23 and a connecting member 24; the bracket 22 is fixedly arranged on the fixing member 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 member 24 is rotatably arranged on the bracket 22, the connecting member 24 is connected to the telescopic end of the telescopic device 23, and the connecting member 24 is hinged to the movable joint 21.

[0040] The bracket 22 is generally L-shaped. The fixed end of the telescopic device 23 is hingedly connected to the bracket 22, and the other end of the telescopic device 23 is hingedly connected to the connector 24. As the telescopic device 23 expands and contracts, the movable joint 21 slides along the fixed pipe 20, so that the discharge port 31 of the dust collection box 30 can be connected to the fixed pipe 20 through the movable joint 21. In this embodiment, the telescopic device 23 uses a pneumatic cylinder. In other embodiments, the telescopic device 23 can also use an electric cylinder or a hydraulic cylinder, etc., without limitation.

[0041] 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. The end of the first connecting portion 241 facing away from the second connecting portion 242 is hinged to the telescopic end of the telescopic device 23. The second connecting portion 242 is hinged to the movable joint 21.

[0042] The first connecting part 241 is a straight rod, and the second connecting part 242 is a U-shaped rod. One end of the first connecting part 241 is hinged to the telescopic end of the telescopic device 23, and the other end of the first connecting part 241 is connected to the middle of the second connecting part 242. The two ends of the second connecting 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.

[0043] Please refer to Figure 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 connecting portion 242 of the connecting member 24. The connecting member 24 is hinged to the movable joint 21 through the two hinged arms 25, thereby realizing the connection between the connecting member 24 and the two sides of the movable joint 21.

[0044] Please refer to Figure 5 A hinge seat 26 is fixedly provided on the bracket 22, and the first connecting portion 241 of the connecting member 24 is hingedly provided on the bracket 22 through the hinge seat 26. In this way, the connecting member 24 is rotatably provided 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, and the connecting member 24 drives the movable joint 21 to slide along the fixed pipe 20 through the hinge arms 25 on both sides of the movable joint 21, so as to connect the dust collection box 30 to the fixed pipe 20 through the movable joint 21.

[0045] Please refer to Figures 1 to 3The dust collection device provided by the present invention also includes two sets of sealing assemblies, which are used to seal the discharge port 31 of the dust collection box 30. The two sets of sealing assemblies are arranged on both sides of the fixed component 10. During operation, one of the discharge ports 31 on the dust collection box 30 is connected to the fixed pipeline 20 via the movable joint 21, and the other discharge port 31 on the dust collection box 30 is sealed by the sealing assembly. When it is necessary to rotate 90 degrees to change the cutting direction, the dust collection box 30 is rotated 90 degrees as the connecting head 11 rotates. After the dust collection box 30 rotates 90 degrees, the discharge port 31 previously connected to the fixed pipeline 20 via the movable joint 21 is sealed by the other set of sealing assemblies. As the movable joint 21 moves, the previously sealed discharge port 31 is connected to the fixed pipeline 20 via the movable joint 21, and the dust collection pipeline is connected.

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 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 arranged horizontally. The pressure cover 42 is rotatably connected to the end of the support arm 41 facing away from the fixed plate 40 via a connecting arm 43. During operation, the pressure cover 42 is located directly above the discharge port 31 of the dust collection box 30. The pressure cover 42 seals the discharge port 31 under its own weight, making it easy to use.

[0047] 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. 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 dust collection box 30, ensuring the sealing effect between the pressure cover 42 and the discharge port 31.

[0048] 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.

[0049] Please refer to Figures 1 to 3The dust collection device provided by the present invention also includes a saw blade cover 50, which is fixed to the connector 11 and is disposed outside the saw blade 60. The saw blade 60 is driven to rotate by a drive motor, which can be disposed in the saw blade cover 50. A dust outlet pipe 51 is disposed on the side of the saw blade cover 50. The dust outlet pipe 51 on the saw blade cover 50 is connected to the dust collection box 30 via a second hose 52. The second hose 52 is fixed to the dust collection box 30 and the dust outlet pipe 51 on the saw blade cover 50 via a hose clamp, and the connection is tight.

[0050] The saw blade cover 50 is located outside the saw blade 60. The dust generated by the saw blade 60 during sawing is collected and processed by a dust collection fan, a dust collection box 30, and a fixed pipe 20, thereby preventing harm to the human body and the environment. Because the saw blade cover 50 and the dust collection box 30 are both fixed to the connector 11, the saw blade cover 50 and the dust collection box 30 move synchronously with the movement of the connector 11. Even after changing the sawing direction, the dust generated during sawing can still be collected and processed.

[0051] When the dust collection device provided by the present invention is in operation, one of the discharge ports 31 of the dust collection box 30 is sealed by one of the sealing components, and the other discharge port 31 of the dust collection box 30 is connected to the fixed pipe 20 via the movable joint 21, thereby connecting the dust collection pipe. When the cutting direction needs to be changed by rotating 90 degrees, the connector 11 rotates 90 degrees, and the rotation of the connector 11 drives the dust collection box 30 to rotate 90 degrees. After the dust collection box 30 rotates 90 degrees, the discharge port 31 previously connected to the fixed pipe 20 via the movable joint 21 is sealed by the other sealing component. As the movable joint 21 moves, the previously sealed discharge port 31 is connected to the fixed pipe 20 via the movable joint 21, thereby connecting the dust collection pipe. Even with long-term use, the dust collection pipe is not easily damaged due to frequent changes in cutting direction, thereby ensuring dust collection effect and production efficiency.

[0052] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0053] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
