Abstract
The utility model discloses a high-efficient type extruder extrusion screw rod, including toper reducing section and straight section, the reducing end of toper reducing section with straight section is connected, all be provided with around on toper reducing section and the straight section and extrude the spiral shell section, toper reducing section and straight section are provided with tetragonal stirring arch around between two adjacent two spiral shells, it is protruding that straight section is provided with triangle-shaped around the one end of keeping away from toper reducing section, pitch between the spiral shell on the straight section diminishes gradually from being close to toper reducing section to keeping away from toper reducing section. The utility model discloses simple structure, reasonable in design can realize extruding fast of material to promote its efficiency and the quality of extruding the stirring.
Description
Technical Field
The utility model relates to an extrusion equipment, concretely relates to high-efficient type extruder extrusion screw rod.
Background
The extruder is a special device for stirring and extruding materials, and is usually matched with a film blowing machine, a forming machine and other devices for processing and production. The extruder mainly comprises an extruding cylinder, wherein an extruding screw is arranged in the extruding cylinder, a feeding hole is formed in the extruding cylinder and is connected with a hopper, and when the extruder works, materials fall into the extruding cylinder from the hopper and are stirred and extruded from the extruding cylinder through the extruding screw. The traditional extrusion screw is often single in structure, and only a straight screw is arranged to realize stirring and conveying of materials, and the structure has the defects that: when the material drops to the extrusion cylinder from the hopper in, pile up easily in the feed inlet department of extrusion cylinder, influence the feed efficiency of material, its holistic mixing stirring efficiency is relatively poor moreover, leads to the follow-up material of extruding to be difficult to satisfy the user demand.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design can realize extruding fast of material to promote its high-efficient type extruder extrusion screw rod of extruding the efficiency and the quality of stirring.
Therefore, the utility model discloses an adopt following scheme to realize:
high-efficient type extruder extrusion screw rod, its characterized in that: including toper reducing section and straight section, the reducing end of toper reducing section with straight section connects, all be provided with around on toper reducing section and the straight section and extrude the spiral shell section, toper reducing section and straight section are provided with tetragonal stirring arch around between two adjacent two spiral shells, it is protruding that flat straight section is provided with triangle-shaped encircleing in the one end of keeping away from toper reducing section, pitch between the spiral shell on the straight section is from being close to toper reducing section to keeping away from toper reducing section diminishes gradually.
An annular liquid inlet groove is formed in the screw.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: 1. the structure is simple, the design is reasonable, and the large-scale production can be realized; 2. through setting up toper reducing section and straight section, toper reducing section aligns with the feed inlet of crowded feed cylinder, after the material falls crowded feed cylinder from the feed inlet of crowded feed cylinder in, at first contact with toper reducing section, and transport backward to straight section department under the direction of toper reducing section fast, the material has been avoided piling up of crowded feed cylinder feed inlet department, the feed efficiency of material has effectively been promoted, simultaneously protruding through setting up tetragonal stirring, promote stirring efficiency and the quality of material at the in-process that mixes and forwards, through set up triangle-shaped arch on straight section, can cut the stirring to the material that will extrude, promote the softness that the material was extruded, be convenient for its subsequent shaping.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figure, the utility model discloses a high-efficient type extruder extrusion screw, including toper reducing section 1 and straight section 4, the reducing end and the straight section 4 of toper reducing section 1 are connected, all be provided with on toper reducing section 1 and the straight section 4 with encircleing and extrude spiral shell section 3, toper reducing section 1 and straight section 4 encircle and are provided with tetragonal stirring arch 2 between two adjacent two spiral shells, straight section 4 is provided with triangle-shaped arch 5 in the one end of keeping away from toper reducing section 1 with encircleing, pitch between the spiral shell on straight section 4 diminishes from being close to toper reducing section to keeping away from toper reducing section 1 gradually, promote its pressure of extruding and mixing stirring gradually, guarantee that it can be smooth and easy, the stable stirring that carries out the material is extruded. The annular liquid inlet groove 6 is formed in the screw, liquid with appropriate temperature can be introduced into the annular liquid inlet groove 6 according to use requirements, the overall temperature of the screw is adjusted, and a better extrusion stirring effect is provided.
The utility model discloses an extrusion screw, through setting up toper reducing section 1 and straight section 4, toper reducing section 1 aligns with the feed inlet of crowded feed cylinder, fall crowded feed cylinder back in the feed inlet of crowded feed cylinder when the material, at first with toper reducing section 1 contact, and transport to straight section 4 department backward fast under the direction of toper reducing section 1, the piling up of material in crowded feed cylinder feed port department has been avoided, the feed efficiency of material has effectively been promoted, simultaneously through setting up tetragonal stirring arch 2, promote stirring efficiency and the quality of material at the in-process that the mixture forwarded, through setting up triangle-shaped arch 5 on straight section 4, can cut the stirring to the material that is about to extrude, promote the softness that the material was extruded, be convenient for its subsequent shaping.
Claims (2)
