Description

Technical Field

[0001] This utility model relates to the technical field of anti-splash baffles for aluminum cutting, specifically an anti-splash baffle device for aluminum cutting. Background Technology

[0002] During aluminum processing, especially when using circular saws, grooving machines, or CNC cutting equipment for high-speed cutting, the intense friction between the cutting tool and the aluminum material generates a large amount of metal shavings, fine aluminum powder, and coolant droplets. These substances are easily splashed around under the influence of centrifugal force and airflow disturbance, which not only pollutes the working environment and affects the normal operation of precision equipment components, but also poses a threat to the respiratory system and eye safety of operators. In addition, aluminum powder is a combustible dust, and when it accumulates to a certain concentration in a closed or semi-closed space, there is a potential risk of dust explosion, which seriously violates safety production regulations.

[0003] Most splash guards on the market are fixed transparent covers or thin metal sheet structures, which mainly rely on physical shielding to limit the spread of splashes. However, such guards can only intercept larger particles or droplets, and are almost powerless against micron-sized aluminum powder suspended in the air. Dust can still escape from the gaps in the guards, and long-term accumulation will lead to deterioration of workshop air quality, increase cleaning and maintenance costs, and may clog equipment heat dissipation holes or electrical components. Although some equipment is equipped with independent external dust collection hoods, their positions are far from the cutting point, resulting in low collection efficiency and susceptibility to airflow interference, making it impossible to achieve source control.

[0004] Although existing technologies have attempted to install local exhaust devices in the cutting area, they are often bulky, separate from the baffle, and difficult to adapt to different models. Furthermore, they do not consider the risk of large particles and coolant mixtures clogging the dust collection pipes. More importantly, existing baffles lack an integrated design with the dust collection function, failing to form a synergistic protection mechanism of "shielding + negative pressure capture + primary separation". Therefore, an aluminum cutting anti-splash baffle device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum cutting anti-splash baffle device, which features double-sided movable baffles that adaptively fit the workpiece, an integrated negative pressure dust collection and sedimentation separation structure inside the baffle, a modular collection frame for easy cleaning, and a dust collection hole with a detachable dust collection cover. It solves the problems of traditional anti-splash baffles that can only passively block, cannot effectively control the dispersion of suspended aluminum powder, large particles and coolant can easily clog the dust collection pipe, and are inconvenient to maintain.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A splash guard device for aluminum cutting is provided, including a fixed baffle. Rotary rods are rotatably mounted on both the left and right sides of the fixed baffle. A first movable baffle is fixedly mounted on the surface of the right rotating rod, and a second movable baffle is fixedly mounted on the surface of the left rotating rod. A dustproof component is provided inside the second movable baffle. The dustproof component includes an installation cavity located inside the second movable baffle, a collection frame installed inside the installation cavity, and a through hole on one side of the collection frame. A sealing plate is bolted to the surface of the second movable baffle located on one side of the installation cavity. A connecting pipe is fixedly mounted inside the sealing plate, and a dust collection device is installed on one side of the connecting pipe via a threaded joint. A settling chamber is located inside the second movable baffle located at the top of the installation cavity, and a negative pressure chamber is located inside the second movable baffle located at the top of the settling chamber. Multiple dust collection holes are formed on the inner wall of the second movable baffle, and dust collection covers are threadedly connected to the inner walls of each of the multiple dust collection holes.

[0007] Furthermore, the first movable baffle and the second movable baffle are symmetrically distributed on the left and right sides of the fixed baffle.

[0008] Furthermore, the collection frame has a drawer-type structure, and its outer contour matches the inner contour of the mounting cavity. It can be slidably inserted into the mounting cavity in the front-back direction. The through hole is opened on the surface of the collection frame and is located near the outer side of the second movable baffle, corresponding to the inlet end of the connecting pipe.

[0009] Furthermore, the connecting pipe is a hollow round pipe, one end of which passes through the sealing plate and the through hole and extends into the mounting cavity.

[0010] Furthermore, the settling chamber is located above the installation cavity and has a cross-section smaller than the installation cavity. Its bottom is connected to the installation cavity and its top is connected to the negative pressure cavity. The negative pressure cavity is located above the settling chamber and has a cross-section smaller than the rectangular channel of the settling chamber.

[0011] Furthermore, the multiple dust hoods, dust holes, negative pressure chambers, settling chambers, collection frames, and connecting pipes are interconnected, and the multiple dust hoods are designed at an angle.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This aluminum cutting splash guard device integrates dustproof components inside the second movable baffle, forming an internal airflow channel that is sequentially connected by a dust suction hood, dust suction hole, negative pressure chamber, settling chamber, collection frame and connecting pipe. The dust generated during cutting enters the negative pressure chamber through the dust suction hood under negative pressure, and then large particles fall into the collection frame after being decelerated in the settling chamber. This effectively reduces impurities entering the external dust collection equipment and reduces the risk of pipe blockage.

[0013] 2. This aluminum cutting anti-splash baffle device features two movable baffles, No. 1 and No. 2, symmetrically rotated and installed on both sides of a fixed baffle. These baffles can adaptively swing with the workpiece position to fit the aluminum surface. The collection frame adopts a drawer-type structure with a removable sealing plate for easy cleaning of accumulated debris. The dust suction hood is threaded and inclined, balancing sealing and directional collection. The overall structure is compact, easy to maintain, and integrates anti-splash and anti-dust functions.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The aluminum cutting anti-splash baffle device in this embodiment includes a fixed baffle 1. Rotating rods 2 are rotatably installed on both the left and right sides inside the fixed baffle 1. A first movable baffle 3 is fixedly installed on the surface of the right rotating rod 2, and a second movable baffle 4 is fixedly installed on the surface of the left rotating rod 2. A dustproof component 5 is provided inside the second movable baffle 4.

[0019] It should be noted that during aluminum processing, the intense friction between the cutting tool and the aluminum material generates a large amount of metal shavings, fine aluminum powder, and coolant droplets. These substances are easily splashed around under the influence of centrifugal force and airflow disturbance, which not only pollutes the working environment and affects the normal operation of precision equipment components, but also poses a threat to the respiratory system and eye safety of operators. Using splash guards can absorb these dust particles and prevent pollution of the working environment.

[0020] Specifically, during operation, the fixed baffle 1 is installed in front of the blade of the aluminum cutting equipment. The first movable baffle 3 and the second movable baffle 4 are respectively connected to the left and right sides of the fixed baffle 1 by rotating rod 2. They can automatically swing according to the thickness or position of the aluminum workpiece, keep in contact with the workpiece surface, and form a dynamic sealing protection.

[0021] Metal dust and debris generated during the cutting process are confined within a space enclosed by a fixed baffle 1, a first movable baffle 3, and a second movable baffle 4. The dustproof component 5 integrated inside the second movable baffle 4 effectively prevents dust from overflowing under the action of an external dust collection device 56, achieving integrated splash and dust prevention.

[0022] The dustproof component 5 includes an installation cavity 51 located inside the second movable baffle 4. A collection frame 52 is installed inside the installation cavity 51. A through hole 53 is provided on one side of the inside of the collection frame 52. A sealing plate 54 is bolted to the surface of the second movable baffle 4 and located on one side of the installation cavity 51. A connecting pipe 55 is fixedly installed inside the sealing plate 54. A dust collection device 56 is installed on one side of the connecting pipe 55 through a threaded joint. A settling chamber 57 is provided inside the second movable baffle 4 and located at the top of the installation cavity 51. A negative pressure chamber 58 is provided inside the second movable baffle 4 and located at the top of the settling chamber 57. Multiple dust collection holes 59 are provided on the inner wall of the second movable baffle 4. A dust collection cover 50 is threadedly connected to the inner wall of each of the multiple dust collection holes 59.

[0023] Settling chamber 57 is located above installation cavity 51 and has a smaller cross-section than installation cavity 51. Its bottom is connected to installation cavity 51 and its top is connected to negative pressure cavity 58. The negative pressure chamber 58 is located above the settling chamber 57 and has a cross-section smaller than the rectangular channel of the settling chamber 57.

[0024] Specifically, during operation, the external vacuuming device 56 creates negative pressure in the negative pressure chamber 58 through the connecting pipe 55, causing dust from the cutting area to enter the suction hole 59 through the dust hood 50 and flow into the negative pressure chamber 58. The airflow then enters the enlarged settling chamber 57 downwards, where the flow rate decreases. Larger particles and droplets settle into the mounting chamber 51 below due to gravity and fall into the collection frame 52. The purified airflow is discharged to the vacuuming device 56 through the through hole 53 and the connecting pipe 55, completing the dust removal process.

[0025] The dustproof component 5 achieves preliminary gas-solid separation through the vertical series arrangement of the negative pressure chamber 58, the settling chamber 57 and the collection frame 52, reducing the impurity load entering the dust collection device 56; the sealing plate 54 is fixed by bolts, which is easy to disassemble for cleaning the collection frame 52; the dust collection hood 50 is threaded to the dust collection hole 59, which not only ensures the sealing performance but also supports replacement or cleaning. The overall integration is high, the anti-clogging performance is strong, and the maintenance is convenient.

[0026] In summary, this aluminum cutting splash guard device forms a dynamic enclosed space through the fixed baffle 1 and the first movable baffle 3 and the second movable baffle 4, which are rotatably installed on the left and right sides, effectively limiting cutting splashes. Among them, the dustproof component 5 integrated in the second movable baffle 4 uses a dust suction hood 50, dust suction hole 59, negative pressure chamber 58, settling chamber 57, collection frame 52 and connecting pipe 55 to form a vertically connected internal airflow channel, which realizes the integration of dust suction, gravity settling and impurity collection under the action of external dust suction equipment 56. The sealing plate 54 is detachably fixed by bolts, which facilitates cleaning of the collection frame 52. The dust suction hood 50 adopts a threaded connection structure, which takes into account both sealing performance and maintenance convenience. The overall structure is compact, with efficient splash and dust prevention, and reliable operation.
