[0035] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0037] In the description, it should also be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the creation of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0039] As Figures 1 to 10As shown in the figure, the dust removal and suction device for masterbatch used in non-woven fabrics disclosed by the present utility model includes a housing 1, a blanking sieve member 2, a dust suction mechanism 3, an air inlet cavity 201 and an exhaust cavity 202. The housing 1 has a top feed port 11, a bottom discharge port 12, an air inlet 101 and an air outlet 102; the blanking sieve member 2 is arranged in the inner cavity of the housing 1 and includes a top sieve plate 21, a bottom plate 22 and an intermediate partition plate 23; the dust suction mechanism 3 includes a dust suction head 30 arranged in the inner cavity and facing the blanking sieve member 2; the air inlet cavity 201 is surrounded by the top sieve plate 21 and the intermediate partition plate 23 and is communicated with the air inlet 101; the exhaust cavity 202 is surrounded by the bottom plate 22 and the intermediate partition plate 23 and is communicated with the air outlet 102; the bottom plate 22 is provided with exhaust holes 220 communicated with the exhaust cavity 202.

[0040] By adjusting the blanking path of the masterbatch through the blanking sieve member 2, the residence time of the masterbatch in the housing is improved, thereby enhancing the dust removal and suction effect; by making the masterbatch slide to be in a dynamic state, the dust generated by mechanical friction is reduced, and combined with the airflow in the air inlet cavity 201 to blow away the dust, and the negative pressure in the exhaust cavity 202 and the dust suction head 30 to carry away the dust, thereby improving the dust removal and suction effect.

[0041] As Figures 7 to 9 shown in the figure, the top sieve plate 21 is a plate with air outlet holes 210, that is, both the top sieve plate 21 and the bottom plate 22 are plates distributed with through holes, and the intermediate partition plate 23 separates the air inlet cavity 201 and the exhaust cavity 202.

[0042] The housing 1 includes an angle fine-tuning member 4 for adjusting the switching between the horizontal state and the inclined state when the blanking sieve member 2 works. According to the principle of the component of gravity, by setting the angle fine-tuning member 4, not only the inclination angle of the blanking sieve member 2 is adjusted to suit the component force of masterbatch with different particle sizes and outer contours along the inclined plane, and the sliding speed is controlled; but also the blanking path of the masterbatch and the residence time in the housing are adjusted, all for the purpose of improving the dust removal and suction effect. For the blanking sieve member in the horizontal state, the time for the airflow to blow away the dust and the negative pressure suction to carry away the dust is appropriately extended. For the blanking sieve member in the inclined state, the masterbatch is dispersed in the housing, which is beneficial to dust removal and makes the dust removal and suction more sufficient.

[0043] Furthermore, the angle fine-tuning member 4 is a telescopic member, and the telescopic member is obliquely arranged between the housing 1 and the blanking sieve member 2. The bottom plate 22 of the blanking sieve member 2 is provided with a limiting member 25 that abuts against the telescopic member. The telescopic member includes but is not limited to a cylinder, and the setting of the limiting member better positions the blanking sieve member 2 and plays a stabilizing role.

[0044] As Figures 1 to 3As shown, in some embodiments, the blanking screen member 2 has a free end 242 and a connecting end 241 that are opposite to each other in the length direction. The blanking screen member 2 includes blanking unit screen members 20 arranged in pairs in the horizontal direction. At least two groups of the paired blanking unit screen members 20 are arranged along the blanking direction. The free ends 242 of the paired blanking unit screen members 20 in the same group are close to each other. The bottom plate 22 of the upper group of blanking unit screen members 20 faces the top screen plate 21 of the lower group of blanking unit screen members 20. The horizontally arranged blanking unit screen members 20 divide the inner cavity of the housing 1 into independent chambers, extending the duration of dust suction and making the dust suction more sufficient. One or both of the paired blanking unit screen members 20 are inclined, thereby adjusting the opening of the color masterbatch blanking. The inclination angles of the paired blanking unit screen members 20 in the same group and the inclination angles of the paired blanking unit screen members in the upper and lower groups can be the same or different. By adjusting the inclination angle of the blanking unit screen members 20, the speed and path of the color masterbatch blanking are adjusted, thereby improving the contact time with the airflow blowing dust in the inner cavity and fully dispersing the color masterbatch. The lengths of the paired blanking unit screen members 20 in the same group can be the same or different. When the lengths of the blanking unit screen members 20 are the same, the dust suction head 30 is arranged on the central axis of the inner cavity of the housing 1. In order to further improve the dust suction effect, the dust suction head 20 can be a dust suction rod 31 passing through the free ends 242 of the paired blanking unit screen members 20 in the upper and lower groups. The central axis of the dust suction rod 31 coincides with the central axis of the inner cavity of the housing 1. The dust suction rod 31 is a hollow rod, and dust suction through holes (not marked) are distributed on the rod wall.

[0045] As Figures 4 to 5 shown, in some other embodiments, the blanking screen member 2 has a free end 242 and a connecting end 241 that are opposite to each other in the length direction. The blanking screen member 2 includes at least two layers of blanking unit screen members 20 arranged in a staggered manner along the blanking direction. The free end 242 of the upper-layer blanking unit screen member 20 is offset towards the connecting end 241 of the lower-layer blanking unit screen member 20.

[0046] In a preferred embodiment, the structure of the blanking screen member 2 of the device as Figures 1 to 3 shown is improved. One of the paired blanking unit screen members 20 in the same group is a first unit screen member, and the other is a second unit screen member. The length of the first unit screen member is greater than the length of the second unit screen member. The upper-group first unit screen members and the lower-group first unit screen members are arranged in a staggered manner. In the case of the same housing height and the same number of layers of the blanking screen member, compared with the paired blanking unit screen members with equal lengths in the same group, the path of the color masterbatch blanking in this solution is longer, and the dust removal and dust suction effects are better. Compared with the blanking unit screen members 20 arranged singly in the same layer and in a staggered manner in the upper and lower layers, such as the device as Figures 4 to 5 shown, the path of the color masterbatch blanking in this solution is similar to that, but the duration of the color masterbatch staying on the blanking unit screen members can be adjusted, with high flexibility and further better dust removal and dust suction effects.

[0047] As Figures 7 to 9As shown in the figure, the structure of the blanking sieve member is optimized. The connecting end 241 of the blanking sieve member 2 includes a core shaft 211 and a sleeve shaft 212. The core shaft 211 is provided with an air inlet 101 and an air outlet 102. An air inlet passage (not marked) and an air outlet passage (not marked) are provided between the core shaft 211 and the sleeve shaft 212. The air inlet passage communicates with the air inlet 101 and the air inlet cavity 201, and the air outlet passage communicates with the air outlet 102 and the air outlet cavity 202. The air inlet 101 is communicated with the inflation device, and the air outlet 102 is communicated with the dust collection mechanism 3.

[0048] As Figure 6 shown in the figure, in order to discharge the material smoothly and prevent the color masterbatch from staying in the shell so as not to affect the production and dust removal of the next masterbatch, further, the bottom surface 100 of the shell 1 is an inclined surface, and the lowest end of the inclined surface is close to the bottom discharge port 12. In order to further extend the blanking path of the color masterbatch, the bottom discharge port 12 is far away from the free end 242 of the blanking sieve member 2 close to the bottom surface 100.

[0049] As Figure 10 shown in the figure, in order to eliminate the static electricity carried by the color masterbatch due to friction so as not to affect the removal of the dust adsorbed on the surface of the color masterbatch, an antistatic member 13 is provided at the top feed port 11, and the antistatic member 13 is connected to an external power source. In order to optimize the structure of the antistatic member 13 and improve the antistatic effect, the antistatic member 13 includes an ion needle 130 and a mounting seat 131 connected to the inner wall of the top feed port 11. In some embodiments, the mounting seat 131 is strip-shaped and the strip-shaped mounting seat 131 is arranged along the axial direction of the top feed port 11; in other embodiments, the mounting seat 131 is ring-shaped and the ring-shaped mounting seat 131 is arranged along the circumferential direction of the top feed port 11.

[0050] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
