Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a milk bottle cap raw material stirring and centralized feeding device, belonging to the technical field of feeding devices. Background Art

[0002] Glass milk bottles used to be easy to break and difficult to recycle, but they were gradually replaced by plastic bottles. Plastic milk bottles are made of plastic particles, which are melted and extruded to feed the mold to make the bottle body or bottle cap.

[0003] With the increasing diversity of milk flavors, some packaging companies are using different colored bottle caps for different flavors to facilitate differentiation and sales. Therefore, when producing milk bottle caps, the feeding device for the raw materials of the bottle cap production needs to frequently switch plastic pellets of different colors. Since plastic pellets are fed to the melt extruder via an auger conveyor, it is easy for plastic pellets of one color to accumulate in the auger conveyor. This can easily lead to two different colored plastic pellets entering the melt extruder, thus affecting the color of the feed.

[0004] In addition, when feeding plastic pellets into the feed port of the melt extruder, the rate at which the auger conveyor outputs the plastic pellets is not stable, which can easily lead to an unstable feed rate of the raw materials. Too much or too little feed will cause the temperature of the plastic pellets in the extrusion tube of the melt extruder to be too high or too low, affecting the discharge temperature of the melt extruder and thus affecting the feeding quality.

One end of the material extrusion pipe 1 is fixedly communicated with a discharge pipe 22. A heating plate 23 is installed on the outer surface of the material extrusion pipe 1. One end of the material extrusion pipe 1 is fixedly installed with a power box 27, and the output end of the power box 27 is in transmission connection with the extrusion screw 21. The power box 27 drives the extrusion screw 21 to rotate. At the same time, the heating plate 23 is used to heat the plastic particles in the material extrusion pipe 1 to melt the plastic particles, and then extrude them through the discharge pipe 22 to supply materials to the mold.

[0031] A screw conveyor 3 is arranged outside the material extrusion pipe 1. The screw conveyor 3 includes a feeding cylinder 31.

[0032] Please refer particularly to Figure 4 , a conveying motor 33 is fixedly connected to the outer surface of the feeding cylinder 31. The output end of the conveying motor 33 is fixedly connected with a screw 32. The screw 32 is rotatably connected to the inner wall of the feeding cylinder 31. The bottom end of the feeding cylinder 31 is fixedly communicated with a stirrer 34. The top end of the feeding cylinder 31 is fixedly communicated with a feeding pipe 35.

[0033] In the screw conveyor 3, the plastic particles and related production raw materials are stirred by the stirrer 34, and then the raw materials are lifted to the top of the feeding cylinder 31 by the rotation of the screw 32 and then flow out through the feeding pipe 35.

[0034] Please refer particularly to Figure 2 , Figure 3 and Figure 5 , a feeding mechanism 4 is arranged outside the material extrusion pipe 1. The feeding mechanism 4 includes a feeding box 41. The bottom end of the feeding box 41 is fixedly communicated with the feeding end of the material extrusion pipe 1. A servo motor 43 is fixedly connected to the outer surface of the feeding box 41. The output end of the servo motor 43 is fixedly connected with an impeller 42. The impeller 42 is rotatably connected to the inner wall of the feeding box 41.

[0035] Through the above technical solution, the plastic particles flow into the feeding box 41 through the feeding pipe 35, and then the rotation of the impeller 42 is controlled by the servo motor 43, so that the plastic particles can fall into the material extrusion pipe 1 at a stable rate, making the feeding rate stable.

[0036] Please refer particularly to Figure 5 and Figure 6, a guide pipe 44 is fixedly connected to the middle of the feeding box 41. A guide box 47 is slidably connected to the inner wall of the guide pipe 44. A threaded block 410 is fixedly connected to the bottom surface of the guide box 47. A material scooping groove adapted to the threaded block 410 is formed in the bottom surface of the guide pipe 44. The bottom end of the threaded block 410 penetrates through the material scooping groove and is threadedly sleeved with a threaded rod 49.

[0037] Among them, a forward and reverse motor 48 is fixedly connected to the bottom surface of the guide pipe 44. The output end of the forward and reverse motor 48 is fixedly connected to the threaded rod 49.

[0038] Among them, one end of the guide pipe 44 far from the feeding box 41 is fixedly connected to a recycling box 45. A material receiving basket 46 is slidably connected to the inner wall of the recycling box 45.

[0039] When it is necessary to replace plastic particles of different colors, control the forward and reverse motor 48 to drive the threaded rod 49 to rotate, so that the threaded rod 49 rotates to drive the guide box 47 to extend into the feeding box 41. The excess raw materials in the feeding box 41 will fall into the guide box 47 and be collected in the recycling box 45 through the guide pipe 44, so as to discharge all the plastic particles of the previous color into the recycling box 45, and avoid the situation of color mixing when two different colors of plastic particles enter the extrusion pipe 1.

[0040] Please refer to Figure 3 , a cooling pipe 26 is fixedly connected to the outer surface of the above-mentioned constant temperature medium box 25.

The water pump 24 is fixedly connected to the outer surface of the constant temperature medium box 25. After the plastic particles in the extrusion pipe 1 are heated and melted, they are extruded through the discharge pipe 22 to supply materials to the mold. By means of the water pump 24, the constant temperature medium between the constant temperature medium box 25 and the cooling pipe 26 circulates, which can prevent the temperature of the molten plastic in the discharge pipe 22 from being too high or too low, keep the feeding temperature relatively stable, and improve the feeding quality.

[0041] Among them, the constant temperature medium box 25 is composed of a temperature sensor, a heating element, a refrigerating element and a controller to control the temperature of the fluid medium, and can be implemented in combination with the existing technology.

[0042] When the present utility model is in use: the plastic particles and related production raw materials are stirred by a stirrer 34, and then the raw materials are lifted to the top of the feeding cylinder 31 by the rotation of the auger 32, and then flow out through the feeding pipe 35 into the feeding box 41. At the same time, by controlling the rotation of the impeller 42 by a servo motor 43, the plastic particles can fall into the extrusion pipe 1 at a stable rate, making the feeding rate stable, so as to avoid the situation that the temperature in the extrusion pipe 1 of the melting and extrusion machine is too high or too low, keep the feeding temperature relatively stable, and improve the feeding quality.

[0043] When it is necessary to replace plastic particles of different colors, control the forward and reverse motor 48 to drive the threaded rod 49 to rotate, so that the rotation of the threaded rod 49 drives the material guide box 47 to extend into the feeding box 41. The excess raw materials in the feeding box 41 will fall into the material guide box 47 and be collected in the recycling box 45 through the material guide pipe 44, so as to discharge all the plastic particles of the previous color into the recycling box 45, avoiding the situation of color mixing when two different colors of plastic particles enter the extrusion pipe 1.

[0044] In addition, by circulating the constant temperature medium between the constant temperature medium box 25 and the cooling pipe 26 through the water pump 24, it is possible to prevent the temperature of the molten plastic in the discharge pipe 22 from being too high or too low, maintain the feeding temperature relatively stable, and further improve the feeding quality.
