Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch production, in particular to a uniform feeding hopper. Background Art

[0002] In the early stages of masterbatch production, the feed hopper plays a critical role, feeding the raw materials into the subsequent heating and mixing steps. Existing technologies typically design a large-capacity container for loading the raw materials to be processed. These raw materials can be various forms of polymer pellets, powders, or additives.

[0003] However, in actual operation, since the materials in the feed hopper are often raw materials from the same batch added at one time, this results in uneven material distribution in the stage before stirring and melting.

[0004] Furthermore, during melting, sufficient stirring is required, not just stirring for the purpose of uniform heating of the material. Therefore, if the stirring time is reduced, uneven mixing of the material will result. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a uniform feeding hopper, which solves the technical problem that the feeding hopper in the production of masterbatch cannot perform uniform feeding.

[0006] According to an embodiment of the present invention, a uniform feeding hopper is provided, comprising:

[0007] Several storage bins: the storage bins are fan-shaped ring structures, and all the storage bins are evenly distributed around the circumference to form a full circle structure;

[0008] Uniform discharge pipe: The uniform discharge pipe is arranged at the lower side of the storage bin, and chambers are evenly distributed in the circumference of the uniform discharge pipe, and each chamber is connected to a corresponding storage bin;

[0009] Uniform discharging device: The uniform discharging device is arranged at the center of the circle formed by all the storage bins. The uniform discharging device is connected to a feed piece and a discharge piece in a transmission manner. The feed piece is arranged at one end of the uniform discharging pipe close to the storage bin, and the discharge piece is arranged at the other end.

[0010] The feed plate is provided with a feed port, the discharge plate is provided with a discharge port, and the feed port and the discharge port are staggered.

[0011] The technical principle of the present utility model is as follows: Different materials are placed in each storage bin, and the quantity of materials in each storage bin is in a set ratio. Then, the uniform discharging device starts to rotate, and the feeding piece rotates accordingly. The materials in the storage bin at the feeding port fall into the chamber for temporary storage, realizing cyclic small-quantity feeding. The feeding quantity is the volume of the chamber. At the same time, the discharging piece also rotates accordingly, and the materials in the chamber at the discharging port fall out for discharging. The discharging quantity is the volume of the chamber, thereby realizing sequential small-batch material storage, making the discharged materials relatively uniform. Since the feeding port and the discharging port are arranged in a staggered manner, feeding will not occur while discharging, ensuring the stability of the discharging quantity.

[0012] Compared with the prior art, the present utility model has the following beneficial effects: By means of the cooperation of the feeding port and the discharging port arranged in a staggered manner on the feeding piece and the discharging piece, the storage bin and the uniform discharging pipe with a chamber, it solves the technical problem that the feeding hopper in masterbatch production cannot feed evenly.

[0013] Furthermore, all the storage bins form an inverted frustum structure, the bottom of the storage bin is an opening, and the opening is connected to the uniform discharging pipe.

[0014] Furthermore, the uniform discharging device includes a driving motor and a driving rod connected to the driving motor. The driving motor is fixed on the upper side of the storage bin, and the driving pipe penetrates into the center of the whole circle formed by all the storage bins and is connected to the center of the uniform discharging pipe to connect the feeding piece and the discharging piece.

[0015] Furthermore, a through transmission channel is provided in the center of the uniform discharging pipe and all the storage bins, and the driving rod is arranged in the transmission channel.

[0016] Furthermore, the shape of the discharging port is the same as the cross-sectional shape of one chamber.

[0017] Furthermore, the shape of the discharging port is the same as the sum of the cross-sectional shapes of two or more chambers.

[0018] Furthermore, the shape of the feeding port and the shape of the discharging port form a complete circle after combination.

[0019] Furthermore, both the feeding piece and the discharging piece include a main body part and a sector-shaped mounting part. The center of the main body part is connected to the uniform discharging device. Sector-shaped holes are circumferentially and evenly distributed on the main body part, and the number of the sector-shaped holes corresponds to the number of chambers. The sector-shaped mounting part is mounted on the sector-shaped holes.

[0020] Furthermore, an inclined surface is provided on the side of the sector-shaped hole close to the storage bin, and a mating surface is provided on the edge of the sector-shaped mounting part. The mating surface closely adheres to the inclined surface.

[0021] Furthermore, a sensor is provided at the position of the feeding piece corresponding to the discharging port. Brief Description of the Drawings

[0033] like Figure 1-3 As shown, a feed port 331 is provided on the feed piece 330, and a discharge port 341 is provided on the discharge piece 340. The feed port 331 and the discharge port 341 are staggered.

The shapes of the feed port 331 and the discharge port 341 can be changed according to actual needs. Take the discharge port 341 as an example: if only one fan-shaped mounting portion 360 is removed, the shape of the discharge port 341 is the same as the cross-sectional shape of a chamber 210; if two or three adjacent fan-shaped mounting portions 360 are removed, the shape of the discharge port 341 is the same as the sum of the cross-sectional shapes of two or three chambers 210.
