In the technical scheme, the side of the support frame is provided with the side slide rail and the two slide blocks, each slide block is provided with the support plate in an L shape, one end of each support plate is fixed with the corresponding slide block, and the other end of each support plate is fixed with one color masterbatch tank.
In the technical scheme, the two ends of the blanking device and the cavity of the support frame form a discharging area.
In the technical scheme, the two ends of the supporting plate are connected with the sliding block or the color masterbatch tank through screws.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use, the switching of various color masterbatch can be accomplished fast moreover to the supply color masterbatch that can be even.

Wherein: 1. the automatic feeding device comprises a support frame, 2 parts of a feeder, 3 parts of a motor, 4 parts of a top surface slide rail, 5 parts of a left color masterbatch tank, 6 parts of a right color masterbatch tank, 7 parts of a discharge chute, 8 parts of a discharge pipe, 9 parts of a PBT (polybutylene terephthalate) discharge tank, 10 parts of a side surface slide rail, 11 parts of a slide block, 12 parts of a support plate and 13 parts of a discharge area.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, 2 and 3, the color masterbatch supply and fast switching device comprises a color masterbatch tank, a support frame 1, a material discharging device 2, a motor 3 and slide rails, wherein the top surface of the support frame 1 is provided with a top surface slide rail 4, the color masterbatch tank is provided with two color masterbatch tanks, namely a left color masterbatch tank 5 and a right color masterbatch tank 6, the bottoms of the two color masterbatch tanks are connected with the support frame 1 through the top surface slide rail 4, the center of the support frame 1 is provided with a cavity, the support frame 1 is provided with an open slot, the material discharging device 2 is of a stepped shaft structure with a large middle part and two small ends, the material discharging device 2 is arranged in the support frame 1, one end of the material discharging device 2 is connected with an output shaft of the motor 3, the outer wall of the middle part of the material discharging device 2 is provided with a circle of hemispherical discharging chute 7 for discharging, the bottom of the color masterbatch tank is provided with an arc surface attached to the shaft in the, the support frame 1 is equipped with blowpit complex discharge tube 8, discharge tube and PBT blanking jar 9's unloading pipe intercommunication.
Left side masterbatch jar 5 and right side masterbatch jar 6 only one carries out the masterbatch and supplies, move to blowpit 7 department when right side masterbatch jar 6, the masterbatch in right side masterbatch jar 6 falls into blowpit 7 through the blanking passageway to it is rotatory downwards under the drive of motor 3, when the blowpit 7 that has filled with the masterbatch moves to the discharge tube upper end opening part, the discharge tube is gone into in the masterbatch in the blowpit 7 under the action of gravity, and mix the process that gets into on next step with the supplied materials that comes from in the PBT feed tank 9. The working principle of the left color masterbatch tank 5 is the same as that of the right color masterbatch tank 6, and different color masterbatches are filled into the two color masterbatch tanks, so that the switching can be performed quickly as required. And because the number of the discharge chutes 7 is limited, the color masterbatch carried each time is limited, and after the color masterbatch tanks are switched, new color masterbatch can quickly move from the color masterbatch tanks to the discharge chutes 7 through the blanking channels, so that the waste of a large amount of materials is avoided.
In the above technical scheme, the side of the support frame 1 is provided with a side slide rail 10 and two sliders 11, each slider 11 is provided with an L-shaped support plate 12, one end of each support plate 12 is fixed with the corresponding slider 11, and the other end of each support plate is fixed with one color masterbatch tank. The bottom of the color masterbatch tank is supported by the top surface slide rail 4, the side surface slide rail 10 and the support plate 12, so that the stability is better, and the smoothness of movement is also better.
In the technical scheme, the two ends of the blanking device 2 and the cavity of the support frame 1 form a discharging area. Because the arcwall face of left side color masterbatch jar 5 and right side color masterbatch jar 6 bottom is the arcwall face of laminating with the middle part of glassware down, and the both ends of glassware 2 are less, when left side color masterbatch jar 5 moved to the left end, left side color masterbatch jar 5's arcwall face was gapped with the left end of glassware 2 down, and at this moment, the color masterbatch in left side color masterbatch jar 5 discharges through the blanking passageway and arranges the material district, and operating personnel can take away the color masterbatch of discharging.
In the technical scheme, the two ends of the supporting plate are connected with the sliding block or the color masterbatch tank through screws.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
