Description

Technical Field

[0001] The utility model relates to the field of extruders, in particular to an inner tube extruder for producing butyl inner tubes. Background Art

[0002] Butyl inner tube is a tire inner tube made of butyl rubber material. Butyl rubber has good air tightness, heat resistance, aging resistance and damping properties. Butyl inner tube production refers to the process of manufacturing butyl inner tube finished products through a series of processing techniques and processes for butyl rubber and other raw materials. The butyl inner tube production process usually includes the preparation and mixing of raw materials, plasticizing and mixing of rubber, extrusion molding, vulcanization treatment, trimming and inspection.

[0003] Butyl inner tube extruder is a kind of mechanical equipment specially used to process butyl rubber material into the shape of butyl inner tube. Butyl inner tube extruder usually consists of drive device, feeding system, screw, barrel, heating and cooling system, mold and other parts. The fully plasticized rubber is extruded through a mold of a specific shape to form the preliminary shape of the butyl inner tube, preparing for subsequent processing steps.

[0004] However, when the existing extruder is used, it is not conducive to chopping the block-shaped butyl rubber raw material. When the block-shaped butyl rubber raw material is placed in the extruder, it will affect the feeding of the block-shaped butyl rubber raw material. It is not convenient to process the block-shaped butyl rubber raw material, which is not conducive to the use of the extruder and will affect the processing of the butyl inner tube.

[0005] Therefore, we propose an inner tube extruder for producing butyl inner tubes. Utility Model Content

The sealing gasket 15 helps to limit and seal between the retaining hole 14 on the feed frame 4 and the movable baffle 13. In the middle of the bottom of the surface of the end of the feed frame 4 away from the retaining hole 14, a hydraulic cylinder 12 is installed corresponding to the movable baffle 13. The hydraulic cylinder 12 is in a horizontal state, and the output rod of the hydraulic cylinder 12 faces the feed frame 4. The feed frame 4 can fix and limit the hydraulic cylinder 12, facilitating the stable use of the hydraulic cylinder 12.

[0038] The working principle of the utility model is: during use, the support leg 2 is stably placed at the position where it needs to be used, which is convenient for stable use of the support leg 2, the support leg 2 can support and limit the butyl inner tube extruder body 1 and the various components assembled on the butyl inner tube extruder body 1, which is helpful for stable use of the butyl inner tube extruder body 1 and the various components assembled on the butyl inner tube extruder body 1, the butyl inner tube extruder body 1 can support and limit the feed hopper 3, which is convenient for stable use of the feed hopper 3, the feed hopper 3 can support and limit the feed frame 4 and the various components assembled on the feed frame 4, which is helpful for stable use of the feed frame 4 and the various components assembled on the feed frame 4.

[0039] The baffle cover 5 is removed by the handle 6 so that the baffle cover 5 cancels the shielding and protection on the top of the feed frame 4, and the butyl rubber raw material is further placed in the feed frame 4, and the rotating motor 7 on the feed frame 4 is turned on. The feed frame 4 can fix and limit the rotating motor 7, which is convenient for the stable use of the rotating motor 7.

When the movable baffle 13 moves, it can drive the limiting rod 16 to move along the limiting hole 17 on the feed frame 4. The feed frame 4 can limit the movable baffle 13 through the limiting hole 17 and the limiting rod 16, which is helpful to stably move the movable baffle 13.

[0041] After the movable baffle 13 is moved to the outside of the feed frame 4, the movable baffle 13 cancels the blocking and limiting effect on the butyl rubber raw material, and the butyl rubber raw material in the feed frame 4 will fall into the feed hopper 3, and the butyl rubber raw material in the feed hopper 3 will enter the butyl inner tube extruder body 1 through the feed port on the butyl inner tube extruder body 1, and the butyl inner tube extruder body 1 is further opened. In the state where the butyl inner tube extruder body 1 is opened, the butyl inner tube extruder body 1 can process the butyl rubber raw material, and after the butyl inner tube extruder body 1 completes the processing of the butyl rubber raw material, it will extrude the processed butyl inner tube through the discharge port to complete the processing of the butyl inner tube.

[0042] During use, it is helpful to cut the block-shaped butyl rubber raw material into pieces. When the block-shaped butyl rubber raw material is placed in the butyl inner tube extruder main body 1, it is convenient to feed the block-shaped butyl rubber raw material, and the block-shaped butyl rubber raw material can be conveniently processed, which helps to use the butyl inner tube extruder main body 1 and is beneficial to the processing of butyl inner tubes.
