Through the steer-by-wire system, smoother and more accurate vehicle control can be achieved, improving the driving experience and safety. As one of the most important components in the steer-by-wire system, the production quality of the circuit board is related to the reliability and safety of the steer-by-wire system. PVC board separators are used in the production process of circuit boards. The board separator is mainly used to cut and separate the connected PVC circuit boards into single units.

[0003] A large amount of cutting dust is generated during the cutting and separation of the PVC circuit board. The flying cutting dust not only affects the production environment of the workshop, but also affects the health of workers who directly inhale it. Currently, most cutting dust is directly treated by dust suction devices set at fixed points, which has poor dust suction effect. CONTENT OF THE INVENTION

[0004] In order to improve the problem of poor dust suction effect of the dust suction device set at the fixed point, the application provides a dust suction device of a PVC board separator.

[0005] The dust suction device of the PVC board separator provided by the application adopts the following technical scheme:

The air inlet of the dust suction machine is connected to the internal space of the cover shell through a dust suction pipe, and the air outlet of the dust suction machine is connected to the dust collecting mechanism.

[0007] By adopting the above technical scheme, the cover shell covers the cutting station of the board separator, which can prevent the dust from spreading to the working environment and reduce environmental pollution. The cleaning mechanism is arranged on the cover shell and is used to clean the dust on the board separator, which ensures that the cutting area remains clean and improves the production efficiency. The air inlet of the dust suction machine is connected to the internal space of the cover shell through a dust suction pipe, which can timely remove the dust collected by the cleaning mechanism and ensure the working efficiency. The dust collecting mechanism is connected to the air outlet of the dust suction machine, which further filters and collects the dust to avoid secondary pollution. The cooperation of the cleaning mechanism and the dust suction machine enables the cutting dust to be better cleaned, which improves the problem of poor dust suction effect of the dust suction device set at the fixed point.

DETAILED DESCRIPTION

[0029] The following will be described in combination with the drawings. Figures 1-3 The present application will be further described in detail.

[0030] The embodiment of the present application discloses a dust collecting device of a PVC board separating machine. Referring to Figure 1The dust suction device of the PVC board separating machine comprises a cover shell 1, a dust suction machine 2, a dust collecting mechanism 3 and a cleaning mechanism 4. The cover shell 1 is arranged on the cutting station of the board separating machine, and covers the cutting area of the PVC circuit board to form a certain degree of closed space, preventing the cutting dust from flying into the workshop. The cleaning mechanism 4 is arranged on the cover shell 1 and is used for cleaning the dust on the board separating machine. The dust suction machine 2 adopts a high-performance centrifugal fan, which has the characteristics of high air volume and low noise. The air inlet of the dust suction machine 2 is communicated with the internal space of the cover shell 1 through a dust suction pipe 5, the air outlet of the dust suction machine 2 is connected with the dust collecting mechanism 3, and the dust collecting mechanism 3 is used for separating and collecting the cutting dust. The cleaning mechanism 4 cooperates with the dust suction machine 2 to achieve the effect of efficiently removing the dust generated in the cutting process, and improves the problem that the dust suction effect of the fixed-point dust collector is poor.

[0031] Specifically, the cover shell 1 comprises a main body 11 made of metal plate and an observation window 12 made of transparent plastic, which facilitates the real-time monitoring of the cutting process by the operator. A ventilation hole 13 is formed in one side wall of the cover shell 1. The cleaning mechanism 4 comprises an air inlet pipe 41 and a swing assembly. The inner diameter of one end of the air inlet pipe 41 is larger than that of the other end. The end of the air inlet pipe 41 with the larger inner diameter is communicated with the ventilation hole 13 in the side wall of the cover shell 1 through a corrugated pipe 42, and the air inlet pipe 41 is rotatably connected to the cover shell 1 through a transversely arranged rotating rod 43. The swing assembly is arranged on the cover shell 1 and is used to drive the air inlet pipe 41 to reciprocatingly swing up and down about the rotating rod 43.

[0032] After the dust suction machine 2 is started, the gas outside the cover shell 1 enters the inside of the cover shell 1 through the ventilation hole 13 and the air inlet pipe 41 in sequence. Due to the setting of the inner diameter of the air inlet pipe 41, the gas entering the inside of the cover shell 1 has a high flow rate and a large pressure, thereby blowing the cutting area at a high pressure, and achieving the cleaning of the cutting area. At the same time, the swing assembly drives the air inlet pipe 41 to reciprocatingly swing up and down about the rotating rod 43, increasing the area to be blown and improving the cleaning effect.

[0033] Illustratively, the swing assembly comprises a rotating disc 44, a connecting rod 45 and a rotating motor 46. The rotating motor 46 is fixedly installed on the cover shell 1 in the transverse direction, and the rotating shaft of the rotating motor 46 is coaxially connected with the rotating disc 44. One end of the connecting rod 45 is rotatably connected with the rotating disc 44, and the other end is rotatably connected with the air inlet pipe 41. By starting the rotating motor 46 to drive the rotating disc 44 to rotate, the connecting rod 45 is swung, and the air inlet pipe 41 is driven to reciprocatingly swing, ensuring that the air inlet pipe 41 covers a wider area, improving the cleaning efficiency and cleanliness, and the structure is relatively simple, convenient to use, and effectively removes the residual dust.

[0034] Illustratively, reference is made to Figure 2The dust collecting mechanism 3 is composed of a dust collecting box 31, an atomizing nozzle 32 and a baffle 33. The dust collecting box 31 is provided with an air inlet 311 on one side and an air outlet 312 on the other side, and the air inlet 311 is connected with the air outlet of the dust collector 2. The baffle 33 is provided with a plurality of baffle plates which are spaced apart from each other from the air inlet 311 to the air outlet 312 and are provided with a gap between the baffle plates and the top wall of the dust collecting box 31. The air which is sucked into the dust collector 2 and is mixed with cutting dust is introduced into the dust collecting box 31 through the air inlet 311, and the air is discharged from the air outlet 312 through the gap. The cutting dust mixed in the air is moved downward under the action of gravity and collides with the baffle 33. The baffle 33 can effectively block the larger dust particles, so that the cutting dust falls to the bottom of the dust collecting box 31 and is collected. The atomizing nozzle 32 is arranged on the top wall of the dust collecting box 31 and is connected with an external water source to moisten and settle the dust, thereby further improving the dust removal effect.

[0035] Further, referring to Figures 2-3 The air outlet 312 of the dust collecting box 31 is provided with a breathable screen 6, and a rotating rod 7 is rotatably connected to the breathable screen 6. The rotating rod 7 is provided with rotating blades 71 and bristles 72, and the bristles 72 are in contact with the breathable screen 6. The breathable screen 6 can effectively filter fine particles in the air to prevent them from entering the environment or the interior of the equipment and improve the air quality. The rotating blades 71 on the rotating rod 7 can rotate when the gas flows. The bristles 72 are in contact with the breathable screen 6, and the bristles 72 are brushed against the breathable screen 6 by the rotation of the rotating rod 7, thereby removing the dust accumulated on the screen and preventing the breathable screen 6 from being blocked.

[0036] In addition, the dust collecting box 31 is further connected with a soundproof pipe 8 which is in communication with the air outlet 312 of the dust collecting box 31. The soundproof pipe 8 is provided with soundproof cotton 9 on the outer wall to reduce noise emission and improve the comfort of the working environment.

[0037] The working principle of the dust collecting device of the PVC plate separating machine is as follows: during use, the rotating motor 46 is started to drive the rotating disc 44 to rotate, and the connecting rod 45 is swung, thereby driving the air inlet pipe 41 to swing up and down. Then, the dust collector is started to make the air outside the cover 1 enter the cover 1 through the air holes 13 and the air inlet pipe 41 in sequence. The air entering through the air inlet pipe 41 has a high flow rate and a large pressure, thereby achieving the blowing of the cutting area. The cutting dust which is blown is sucked into the dust collecting box 31 by the dust collector 2, and the cutting dust is well cleaned and absorbed, thereby improving the problem of poor dust collection effect of the fixed dust collector. When the gas passes through the gap between the baffle 33 and the top wall of the dust collecting box 31, the heavy dust naturally falls and collides with the baffle 33. At the same time, the falling dust is collected at the bottom of the dust collecting box 31 under the action of water sprayed by the atomizing nozzle 32. The overall structure is simple and convenient to use.

[0038] The above are all optional embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
