Example one

The color masterbatch feeding device that this embodiment provided is used for production facility.

Referring to fig. 1 to 4 in combination with fig. 5 and 6, the color masterbatch supplying device 1 provided in this embodiment includes a mixing box 11, a storage box 10, and an opening and closing mechanism 12.

Hereinafter, the above-described components of the color masterbatch supplying device 1 will be specifically described.

In the present embodiment, the storage bins 10 are used for storing color concentrates, the number of the storage bins 10 is plural, and at least one storage bin 10 of the plurality of storage bins 10 stores one color. For example, when the number of the magazine cases 10 is four, the four magazine cases 10 may store one color masterbatch respectively, or every two magazine cases 10 of the four magazine cases 10 store one color masterbatch, or two magazine cases 10 of the four magazine cases 10 store a first color masterbatch, and the other two magazine cases 10 store a second color masterbatch and a third color masterbatch respectively. It will be appreciated that a plurality of magazines 10 may be fully or partially activated depending on the circumstances.

That is to say, all the storage boxes 10 of the color masterbatch supply device 1 can form a plurality of color storage modes, at least one color masterbatch can be selectively stored according to the requirement, and the number of the storage boxes 10 required by each color masterbatch can be adjusted according to the requirement.

In this embodiment, the interior of the mixing box 11 is used for mixing color masterbatch, the mixing box 11 has a plurality of inlets 110, and the discharge ports of the storage boxes 10 are connected with the interior of the mixing box 11 through the inlets 110 in a one-to-one manner in an on-off manner, so that after the color masterbatch stored in the storage boxes 10 flows out through the discharge ports, if the storage boxes 10 are communicated with the interior of the mixing box 11 through the inlets 110, the flowing color masterbatch enters the interior of the mixing box 11 through the inlets 110 and is mixed in the mixing box 11. If the outlet of the bin 10 is disconnected from the interior of the mixing box 11 via the inlet 110, the color concentrate stored in the bin 10 will not enter the interior of the mixing box 11. By changing the on-off state and the on-off sequence between the storage box 10 and the mixing box 11, various color masterbatches can be obtained by mixing the mixing box 11, and the color changing production of the color masterbatches is also realized. Wherein the mixing may comprise homochromatic mixing or heterochromatic mixing.

The mixing box 11 has an outlet 111, and the outlet 111 is used for outputting the mixed color masterbatch, wherein the color masterbatch can be output by color change because the color masterbatch can be produced by color change.

As an example, when the number of the magazine cases 10 is four, three magazine cases 10 of the four magazine cases 10 are a first magazine case, and the other magazine case 10 is a second magazine case, the first magazine case stores a first color concentrate, and the second magazine case stores a second color concentrate.

A first reservoir tank and the mixing box 11 are communicated, so that the first color masterbatch is fed into the mixing box 11, and the first color masterbatch is fed to the production equipment 21 through the mixing box 11. Until the first color masterbatch in the first storage box is used up; and the other first storage box is communicated with the mixing box 11, so that the first color master batch is continuously conveyed into the mixing box 11, and the second color master batch is conveyed to the production equipment 21 through the mixing box 11. That is to say, the continuous supply capacity of the first color masterbatch of two storage tanks 10 can be satisfied, compared with the manner of supplying the first color masterbatch by using a single storage tank in the prior art, the number of times and frequency of adding the first color masterbatch can be reduced, and the situation that the first color masterbatch is not added in time can be effectively avoided.

Then, the mixing box 11 is communicated with the last first storage box and the last second storage box simultaneously, so that mixed color output of the first color master batch and the second color master batch can be realized, the storage box 10 and the mixing box 11 do not need to be cleaned, and color changing production can be completed.

In this embodiment, in order to improve the flexibility and the variety of trade look production, color masterbatch feeding device 1 still includes clear material mechanism 13, and clear material mechanism 13 sets up in mixing box 11 and can carry out clear material processing to the color masterbatch of mixing box 11 inner wall.

Before the color of the color masterbatch conveyed to the mixing box 11 changes, the color masterbatch of the mixing box 11 is cleaned by the cleaning mechanism 13 after the last storage box 10 communicated with the mixing box 11 is disconnected and before the next storage box 10 is communicated with the mixing box 11, so that the color mixing error of the next color masterbatch and the last color masterbatch is avoided, and the color difference of the plastic product at the production position of the production equipment 21 using the color masterbatch supply device 1 is avoided.

In this embodiment, the material cleaning mechanism 13 performs material cleaning by blowing, for example, a fan is used to blow or blow the inner wall of the mixing box 11; or, the material cleaning mechanism 13 discharges dry materials in a drying manner, for example, the inner wall of the mixing box 11 is dried by an infrared baking lamp, so as to avoid color mixing; or, the material cleaning mechanism 13 discharges the dry material by blowing and drying, for example, the inner wall of the mixing box 11 is dried by warm air.

Specifically, mixing box 11 is open at the upper end, and outlet 111 is formed at the bottom of mixing box 11, so that the color concentrate can flow toward the discharge port of mixing box 11 under the action of gravity.

The material cleaning mechanism 13 includes an upper cover 130 and an annular nozzle 131. Upper cover 130 is removably attached to the top of mixing box 11 to facilitate replenishment of color concentrate and to maintain cleanliness within mixing box 11.

Optionally, according to the property and characteristics of the color masterbatch, the temperature of the gas sprayed by the annular nozzle 131 is selected, so that when the gas sprayed by the annular nozzle 131 sweeps the color masterbatch, the flowability of the color masterbatch on the inner wall of the mixing box 11 is reduced, the residual quantity of the color masterbatch on the inner wall of the mixing box 11 is reduced, and the thoroughness of sweeping the color masterbatch on the inner wall of the mixing box 11 can be further improved.

In the present embodiment, the opening and closing mechanisms 12 are disposed on the inlets 110 in a one-to-one correspondence, and can open and close the inlets 110 of the mixing boxes 11, so that whether the corresponding storage boxes 10 deliver the color concentrates to the mixing boxes 11 can be controlled by the opening and closing members, and the controllability of the color concentrate supply device 1 is improved.

In the present embodiment, the switch mechanism 12 includes a driver 120 and an opening plate 121. The opening plate 121 is slidably connected with the storage box 10 at the inlet 110, optionally, a slide way is arranged on two sides of the inlet 110, and the opening plate 121 is provided with a slide block slidably mounted in the slide way.

In the present embodiment, the opening plate 121 includes a through-flow portion 1211 and a flow stop portion 1210 connected in series in a slidable direction of the opening plate 121. Alternatively, as shown in fig. 3 and 4, the through-flow portion 1211 is formed by a first plate member having a through-flow hole whose contour can surround the contour of the inlet 110, so that the through-flow portion 1211 can be completely or partially retracted from the inlet 110, providing a structural basis for controlling the flow rate of the color concentrate. The flow stop portion 1210 is formed by a second plate member having an outer circumferential profile capable of surrounding the contour line of the inlet 110, so that the flow stop portion 1210 can completely or partially block the inlet 110, and further provides a structural basis for controlling the flow rate of the color masterbatch. Further, the first plate member and the second plate member are integrally molded.

The driving member 120 is connected to the opening plate 121 and can drive the opening plate 121 to slide back and forth between a first position where the through-flow portion 1211 completely avoids the inlet 110 and a second position where the flow stop portion 1210 completely blocks the inlet 110, that is, when the opening plate 121 moves between the first position and the second position, the through-flow portion 1211 can avoid a part of the inlet 110 and the flow stop portion 1210 can block the other part of the inlet 110, so as to adjust the opening degree of the inlet 110.

Alternatively, the driving member 120 is an electric cylinder, a hydraulic cylinder, or an electric linear slide.
