[0035] like Figures 1 to 2 As shown, Figure 1 The arrow in the middle shows the diversion direction of the diversion cavity. Figure 2 The arrow in the middle shows a schematic diagram of the flow path of the condensate in the groove. An embodiment of the first aspect of the present invention provides a deflector, which includes a cover body 1 having a deflector cavity 11 and an air inlet 12 and an air outlet 13 connected to the deflector cavity 11. The deflector cavity 11 can guide the gas from the air inlet 12 to the air outlet 13, that is, the direction from the air inlet 12 to the air outlet 13 can form a deflection direction of the deflector cavity 11.

[0036] Among them, a collecting part 2 is provided in the guide cavity 11, and the collecting part 2 is provided on the bottom plate 14 of the cover body 1. The collecting part 2 is used to collect the condensate formed in the guide cavity 11, that is, the condensate formed in the cover body 1 will flow downward due to gravity. The collecting part 2 is provided on the bottom plate 14 of the cover body 1, which can collect part or all of the condensate on the flow path of the condensate, reduce the accumulation of condensate and dripping to the coating area 8, reduce product defects of the casting, and reduce the situation of stopping to clean the guide cover, so that the production line operation is more stable, and solves the problem in the related technology that oil smoke is easy to condense and accumulate in the guide cover, and condensate is easy to drip into the coating area 8, causing product defects.

[0037] In this embodiment, the cross-sectional shape of the cover body 1 can be, but is not limited to, rectangular, elliptical or square. The cover body 1 extends axially along the receiving part 6 such as the chilled roller, and the length of the cover body 1 is equal to or greater than the circumferential dimension of the receiving part 6 to facilitate sufficient recovery of oil smoke.

[0038] like Figures 1 to 2As shown, in some embodiments, the collecting portion 2 includes a groove 21 and / or a liquid absorbent member. Optionally, the collecting portion 2 may include a groove 21 having a certain depth. The groove 21 is located on the flow path of the condensate, and the condensate can flow into the groove 21 for collection and recovery. Alternatively, the collecting portion 2 may also include a liquid absorbent member having a certain adsorption property. The liquid absorbent member is located on the flow path of the condensate to absorb the flowing condensate and reduce dripping. Alternatively, the collecting portion 2 may include a groove 21 and a liquid absorbent member. The liquid absorbent member may be disposed within the groove 21 or spaced apart from the groove 21 so that the condensate can be more stably gathered in the groove 21, reducing the condensate from overflowing from the groove 21.

[0039] In this embodiment, the absorbent member may be, but is not limited to, a cotton swab, a sponge, an oil-absorbing blue film, or an oil-absorbing cloth. The absorbent member may be detachably connected to the bottom plate 14 to facilitate replacement of the absorbent member. Optionally, the connection between the absorbent member and the bottom plate 14 may be, but is not limited to, a bolt connection, a clamping connection, or an adhesive connection.

[0040] like Figures 1 to 2 As shown, in some embodiments, a liquid outlet channel 3 is provided on the bottom plate 14, and the liquid outlet channel 3 is connected to the groove 21. A first guide section 211 is provided on the bottom wall of the groove 21. The groove depth of the first guide section 211 gradually increases from a position away from the liquid outlet channel 3 to the liquid outlet channel 3. With this arrangement, the first guide section 211 can guide and converge the condensate flowing into the groove 21 to the liquid outlet channel 3, which not only facilitates the discharge of the condensate in the groove 21, but also reduces the overflow of the condensate from the groove 21.

[0041] In this embodiment, the liquid outlet channel 3 is used to connect to an external driving device such as a pump, so that the condensate can be discharged quickly to reduce accumulation.

[0042] like Figures 1 to 2 As shown, in some embodiments, multiple liquid outlet channels 3 and first guide sections 211 are provided. In the vertical direction of the diversion direction of the diversion cavity 11, multiple liquid outlet channels 3 are located at the two side wall positions of the cover body 1, and the first guide sections 211 are respectively provided corresponding to the positions of the liquid outlet channels 3. With such a configuration, the bottom of the groove 21 is a curved surface structure with a high middle and low sides. After the condensate enters the groove 21, it can flow along the first guide section 211 to the two side positions of the cover body 1, which facilitates the multi-point convergence of the condensate in the groove 21, thereby improving the diversion rate and reducing the overflow of the condensate from the groove 21.

[0043] like Figures 1 to 2As shown, in some embodiments, one or more collecting parts 2 are provided, and can be arranged according to the processing needs of the condensate. When multiple collecting parts 2 are provided, the multiple collecting parts 2 are spaced apart in the diversion direction of the diversion cavity 11, so that the multiple collecting parts 2 can collect the condensate in sections, forming a multi-level barrier, further reducing the dripping of the condensate.

[0044] like Figures 1 to 2 As shown, in some embodiments, the end of the bottom plate 14 at the air inlet is chamfered to form a second guide section 141 on the inner wall of the bottom plate 14. The second guide section 141 gradually increases in height in the diversion direction of the diversion cavity 11 and extends to the collection portion 2. With this configuration, the bottom plate 14 itself has a certain thickness. At the air inlet, the second guide section 141 is provided, and the end of the bottom plate 14 can be transformed from a vertical surface to a pointed end. The oil smoke is guided into the diversion cavity 11 along the second guide section 141, which reduces the obstruction of the oil smoke by the vertical surface of the bottom plate 14 and prevents the oil smoke from condensing on the vertical surface of the end of the bottom plate 14 and dripping onto the coating area 8. Moreover, by extending the second guide section 141 to the collection portion 2, the formation of condensation on the surface of the bottom plate 14 between the second guide section 141 and the collection portion 2 is reduced, further reducing the possibility of condensation dripping onto the coating area 8.

[0045] In this embodiment, the ratio of the thickness of the bottom plate 14 to the length of the second guide section 141 is 1:3-1:5, so that the oil smoke can be more smoothly introduced into the guide cavity 11, reducing the accumulation of oil smoke on the vertical surface of the end of the bottom plate 14. At the same time, the thickness of the bottom plate 14 is taken into consideration to avoid deformation of the bottom plate 14 due to too small thickness, affecting the structural stability of the bottom plate 14, and reducing the impact on the flow path of the guide cavity 11.

[0046] like Figures 1 to 2 As shown, in some embodiments, the cover body 1 further includes a top plate 15, on which a heating element 4 is provided. The heating element 4 can heat the gas temperature in the guide cavity 11 and the coating area 8, and also make the cover body 1 have a certain temperature, thereby reducing the condensation of oil smoke during the guide process, and thereby reducing the generation of condensate.

[0047] In this embodiment, the heating element 4 may be, but is not limited to, a heating plate or an electric heating film, and it only needs to heat the gas in the guide cavity 11 and the coating area 8 .

[0048] like Figures 1 to 2As shown, in some embodiments, a vacuum pumping component 5 is further provided on the cover body 1, and the vacuum pumping component 5 is connected to the air outlet 13. The size of the top plate 15 is larger than the size of the bottom plate 14, that is, in the diversion direction of the guide cavity 11, the length of the top plate 15 is larger than the length of the bottom plate 14, which not only reduces the position interference between the bottom plate 14 and the receiving parts 6 such as the chilling roller, but also enables the top plate 15 to extend to a longer dimension to a position close to the discharge port of the die head 7 or the coating coating path, and can better shield the coating area 8, so that the guide cavity 11 and the coating area 8 form a more stable negative pressure vacuum state, which is convenient for the coating melt to better adhere to the receiving parts 6 such as the chilling roller, thereby improving the melt attachment effect.

[0049] In this embodiment, the vacuum pump 5 can be, but is not limited to, a vacuum pump or an exhaust pipe connected to a vacuum driving device, which can evacuate the inside of the cover body 1.

[0050] like Figures 1 to 3 As shown, an embodiment of the second aspect of the present invention provides a casting device, which includes a receiving part 6, a die head 7 and a guide cover in any of the above-mentioned schemes. The discharge port of the die head 7 is arranged toward the surface of the receiving part 6, the guide cover is arranged on one side of the die head 7, and the air inlet 12 of the cover body 1 is arranged toward the coating area 8 between the discharge port of the die head 7 and the receiving part 6. In this way, the coating area 8 formed between the discharge port of the die head 7 and the receiving part 6 is evacuated by setting the guide cover, which can form a negative pressure vacuum state in the coating area 8, so that the coating and the receiving part 6 are better adhered, and the melt attachment effect is improved. The oil smoke formed after the coating is discharged can also be sucked into the guide cavity 11 of the cover body 1 for discharge. The collecting part 2 in the guide cavity 11 can collect and recycle the condensate generated during the oil smoke diversion process, reduce the condensate dripping into the coating area 8, cause product defects of the casting, and reduce the situation of shutdown for cleaning, so that the production line can operate stably.

[0051] In this embodiment, the receiving member 6 can be a rotating roller such as a chill roller, or a linear conveying structure such as a conveyor belt, as long as it can be coated by the die head 7. The die head 7 can be, but is not limited to, a nozzle or a coating roller.

[0052] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
