Description

Technical Field

[0001] This utility model relates to the field of internal mixer technology, specifically to a twin-screw feed hopper for an internal mixer. Background Technology

[0002] An internal mixer is a machine that uses a pair of rotors of a specific shape that rotate relative to each other to intermittently plasticize and mix polymer materials in a closed state with adjustable temperature and pressure. It is mainly used for plasticizing and mixing rubber, and is also widely used in industries such as plastics processing. It can mix and process various raw materials such as rubber, plastics, and chemical additives to form a homogeneous mixture.

[0003] The internal mixer's twin-screw feed hopper mainly consists of two meshing or non-meshing screws, a feed inlet, and a screw housing. When the internal mixer is running, the twin screws rotate relative to each other within the screw housing. After entering through the feed inlet, the material is driven forward by the rotation of the twin screws, moving within the screw grooves. During this process, the twin screws apply shearing, compressive, and frictional forces to the material, achieving initial mixing, crushing, and conveying, preparing it for subsequent mixing processes within the internal mixer.

[0004] Considering that when the existing internal mixer's twin-screw feed hopper is in operation, when highly viscous materials are fed in, the material flow resistance is large, making it difficult to be pushed by the screw. The materials tend to adhere to the screw and the feed hopper wall, resulting in a limited feeding speed. At the same time, insufficient screw speed and pressure will also reduce the material feeding speed, thereby reducing the effectiveness and efficiency of the internal mixer. Utility Model Content

[0005] The purpose of this invention is to provide a twin-screw feed hopper for a mixer.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A twin-screw feed hopper for an internal mixer is provided, comprising an internal mixer body, a feed hopper, a pushing mechanism, a cleaning mechanism, a locking mechanism, and a cover plate. The feed hopper is fixedly installed on the internal mixer body, the cover plate is hingedly installed on the feed hopper, the pushing mechanism is fixedly installed on the cover plate, and the pushing mechanism is used to push the material in the feed hopper. The cleaning mechanism is fixedly installed on the pushing mechanism and is used to clean the pushing mechanism. The locking mechanism is fixedly installed on the feed hopper and is used to fix the cover plate.

[0008] Furthermore, the pushing mechanism includes an electric push rod, a fixing block, and a pushing plate. The electric push rod is fixedly installed on the cover plate, and the pushing plate is fixedly installed on the output shaft of the electric push rod through the fixing block.

[0009] Furthermore, the pushing mechanism also includes a scraper rod and an L-shaped rod. The scraper rod is fixedly installed on the fixed block by an elastic telescopic rod, and a guide groove is provided on the scraper rod. The L-shaped rod is slidably installed on the guide groove by a guide block.

[0010] Furthermore, the cleaning mechanism includes a movable frame, a hinged rod, and a movable plate. The movable frame is fixedly installed on the scraper rod via a connecting rod, and the movable frame is slidably connected to the pusher plate. The movable frame passes through an elastic telescopic rod. The hinged rod is hinged to the movable frame via a cylindrical block. The movable plate is hinged to the hinged rod, and the movable plate passes through the elastic telescopic rod.

[0011] Furthermore, the locking mechanism includes a housing, a mounting plate, a buckle, and a wedge. The housing is fixedly installed on the feed hopper and has a groove. The mounting plate is connected to the housing by a spring and is slidably connected to the housing. The buckle is fixedly installed on the cover plate and is inserted into the groove. The wedge is fixedly installed on the mounting plate and is engaged with the buckle.

[0012] Furthermore, the locking mechanism also includes a cylindrical rod and a handle. The cylindrical rod is fixedly mounted on the mounting plate and passes through the housing. The handle is fixedly mounted on the cylindrical rod.

[0013] The beneficial effects of this utility model are as follows: The twin-screw feed hopper of this internal mixer, through the set pusher mechanism, can push the material in the feed hopper to the bottom of the feed hopper, thereby overcoming the problem of feeding difficulties caused by high material viscosity or insufficient screw pressure, thus improving the use effect and working efficiency of the internal mixer. At the same time, the set cleaning mechanism can clean the pusher plate to prevent material from adhering to the pusher plate and affecting the quality of subsequent feed materials. In addition, the set locking mechanism can provide a stable fixing effect on the cover plate, preventing the cover plate from shaking during the operation of the internal mixer, causing material leakage and dust entry into the feed hopper, further improving the use effect of the internal mixer.
