DETAILED DESCRIPTION

[0029] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0030] like Figures 1 to 7 As shown, this embodiment proposes a masterbatch automatic feeding mechanism, including:

[0031] A housing 11, wherein the housing 11 has a chamber, a feed port 12 communicating with the chamber is provided at the top of the housing 11, a discharge port 13 communicating with the chamber is provided at the bottom of the housing 11, and an air inlet communicating with the chamber is provided on a side wall of the housing 11;

[0032] A dust removal pump 14, wherein an air inlet end of the dust removal pump 14 is connected to an internal chamber of the housing 11;

[0033] A silo 15, wherein the silo 15 is fixed in the chamber, an opening at the top of the silo 15 is connected to the feed port 12, an opening at the bottom of the silo 15 is connected to the discharge port 13, and a filtering hole is provided on the side wall of the silo 15;

[0034] Buffer rollers 16 , wherein a plurality of buffer rollers 16 are arranged in the material bin 15 , and a spacing is left between adjacent buffer rollers 16 .

[0035] The technical effect of this solution is that the dust in the masterbatch can be effectively collected, the cleanliness of the masterbatch is ensured, and the safety of the masterbatch feeding is improved.

[0036] The masterbatch in this solution enters the silo 15 through the feed port 12, and finally falls into the discharge port 13 through the buffer roller 16 and is discharged and collected. At the same time, the dust removal pump 14 is turned on, and the external air enters the chamber through the air inlet, flows upward through the filter holes of the silo 15, and is discharged from the exhaust port on the top of the housing 11 together with the dust.

[0037] As an implementation of this embodiment, the air inlet is shielded by a door body 17. When the entire device is in a non-working state, the door body 17 is in a closed state and is used to shield the air inlet.

[0038] As an implementation of this embodiment, the buffer roller 16 is fixedly or rotatably disposed in the silo 15 .

[0039] This solution proposes two installation methods of the buffer roller 16, both of which can achieve dispersion of the masterbatch and allow the dust to be completely spread out, so that the dust can be more effectively sucked away and discharged.

[0040] As an implementation mode of this embodiment, the material bin 15 includes a first mesh plate 18 and a second mesh plate 19 , and the material bin 15 is formed between the first mesh plate 18 , the second mesh plate 19 and the side wall of the housing 11 .

[0041] The mesh holes on the first mesh plate 18 and the second mesh plate 19 are the above-mentioned filter holes, which are used to prevent the masterbatch from passing through the mesh holes, so that the masterbatch is completely retained in the silo 15, and at the same time, the dust is discharged and collected through the mesh holes.

[0042] As an implementation of this embodiment, a bracket 20 is fixed on the fixed block of the housing 11. Further, a material plate 21 is slidably arranged on the bracket 20 in a vertical direction, and a distance adjusting member 22 is arranged at the lower end of the material plate 21.

[0043] The height of the material plate 21 is adjusted by the distance adjusting member 22, so as to facilitate the packaging of the discharged masterbatch.

[0044] Furthermore, the distance adjusting member 22 includes a threaded sleeve 31 and a screw 32, wherein the sleeve is fixed to the lower surface of the material plate 21, the screw 32 is screwed into the threaded sleeve 31, and a pad 33 is fixed to the lower end of the screw 32. The height of the material plate 21 is adjusted by rotating the screw 32 to adapt to the specific packaging scenario.

[0045] As an implementation method of this embodiment, an inclined plate is provided in the silo 15 , and a gap is left between the lower end of the inclined plate and the side wall of the silo 15 .

[0046] Furthermore, the number of the inclined plates is three, and the three inclined plates are all located above the buffer roller 16 .

[0047] In this solution, an inclined plate is provided, which is used to increase the movement stroke of the masterbatch on the one hand, and to reduce the impact force of the falling masterbatch on the other hand, so as to reduce the new amount of dust.

[0048] As an implementation mode of this embodiment, the three inclined plates are, in order from top to bottom, a first inclined plate 23, a second inclined plate 24 and a third inclined plate 25, a material blocking component is provided in the silo 15, and the material blocking component is installed on the horizontal portion 30 of the second mesh plate 19 through a spring 29; and the material blocking component is located above the second inclined plate 24, and a material channel is left between the material blocking component and the second inclined plate 24.

[0049] The technical effect of this solution is that, under the joint action of the second inclined plate 24 and the material blocking component, the masterbatch passes through the narrow material channel, so that the masterbatch is spread out, the masterbatch falls more dispersedly, and the dust attached to the masterbatch can be better blown away.

[0050] As an implementation mode of this embodiment, the material blocking component includes a first rotating plate 26 and a second rotating plate 27, the first rotating plate 26 and the second rotating plate 27 are fixed by a rotating column 28, the rotating column 28 is fixed in the silo 15 by a rotating shaft, the first rotating plate 26 is close to the second inclined plate 24, the second rotating plate 27 is located above the first rotating plate 26, and the spring 29 is installed between the second rotating plate 27 and the horizontal part 30.

[0051] The technical effect of this solution is that when the amount of material is particularly large, the force on the first rotating plate 26 increases and is greater than the elastic force of the spring 29. At this time, the first rotating plate 26 and the second rotating plate 27 rotate synchronously, and the opening of the material channel becomes larger, which can more effectively prevent the mother particles from accumulating on the second inclined plate 24.

[0052] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
