Abstract
The utility model belongs to the technical field of extruders, and in particular relates to an extruder with a bent runner nose. The extruder comprises an extruder cylinder, wherein the discharge end of the extruder cylinder is connected with a nose through a connecting pipe; the nose is formed by a frustum shaped casing, a die core in the casing and a closure plate which is arranged at the end part of the casing and the die core and provided with a discharge hole; a wave-shaped concave-convex structure is respectively arranged in each of the inner wall of the casing and the outer wall of the die core, so that a plurality of wave-shaped bent runners are formed between the casing and the die core; and two ends of each wave-shaped bent runner are respectively communicated with the connecting pipe and the discharge hole. According to the extruder, a material can be smoothly extruded by designing the bent runners, the processing efficiency is high, and the produced product quality is high; the electric energy can be effectively saved due to the design of a direct-drive motor; the hopper is arranged on the extruder cylinder and is formed by a cylindrical section and a conical section, and the conical section is connected with the extruder cylinder; and due to the hopper with the structure, the material can enter the extruder cylinder more uniformly.
Description
Technical field
The utility model belongs to extruder technology field, specifically a kind of extruder with curved channel head.
Background technology
At present, extruder on the market, its head inner chamber is smooth flat or curved surface, and this structure cannot be accomplished the function of stable output in material extrusion.Meanwhile, because hopper is cone bucket shape shape, during charging, block.
Utility model content
For the technical problem existing in prior art, the utility model provides a kind of extruder with curved channel head, and this extruder passes through design curved channel, thereby material can steadily be extruded, and working (machining) efficiency is high, and production product quality is better.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of extruder with curved channel head, comprise extruder barrel, the discharge end of extruder barrel is connected with head by tube connector, head is by the overcoat that is frustum, be placed in the core rod of overcoat and be located at overcoat and mandrel tip the shrouding that is provided with discharge opening form, at the inwall of overcoat and the outer wall of core rod, be equipped with the concaveconvex structure of undulate, thereby between overcoat and core rod, form some waveform curved channels, the two ends of described waveform curved channel are communicated with respectively tube connector and discharge opening.
Further, described discharge opening is comprised of some ovalizes and the through hole of arranging continuously on shrouding, and the quantity of the quantity of through hole and waveform curved channel is consistent.
Further, be provided with cardan shaft, be placed in the propelling screw thread on cardan shaft in described extruder barrel, the end of described cardan shaft is connected with the motor of being located at extruder barrel outside.
Further, be also provided with hopper on described extruder barrel, described hopper consists of cylindrical section and conical section, and conical section is connected with extruder barrel.
The extruder with curved channel head of the present utility model, compared with prior art, its beneficial effect shows:
The utility model passes through design curved channel, thereby material can steadily be extruded, and working (machining) efficiency is high, and production product quality is better.In extruder barrel, be provided with cardan shaft, be placed in the propelling screw thread on cardan shaft, the end of cardan shaft is connected with the motor of being located at extruder barrel outside, by direct-drive motor, designs, and can effectively save electric energy.On extruder barrel, be also provided with hopper, hopper consists of cylindrical section and conical section, and conical section is connected with extruder barrel.The hopper of this kind of structure, can make material enter extruder barrel more even.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of shrouding.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.As a kind of preferred embodiment of the present utility model, refer to Fig. 1 and 2, a kind of extruder with curved channel head, comprise extruder barrel 8, the discharge end of extruder barrel 8 is connected with head by tube connector 1, head is by the overcoat 6 that is frustum, be placed in the core rod 5 of overcoat 6 and be located at overcoat 6 and core rod 5 ends the shrouding 4 that is provided with discharge opening 3 form, at the inwall of overcoat 6 and the outer wall of core rod 5, be equipped with the concaveconvex structure 7 of undulate, thereby between overcoat 6 and core rod 5, form some waveform curved channels 2, the two ends of waveform curved channel 2 are communicated with respectively tube connector 1 and discharge opening 3.The utility model passes through design curved channel, thereby material can steadily be extruded, and working (machining) efficiency is high, and production product quality is better
As preferably, discharge opening 3 is comprised of some ovalizes and the through hole of arranging continuously on shrouding 4, and the quantity of the quantity of through hole and waveform curved channel 2 is consistent.Be a kind of for processing the head of pipe material, certainly, the utility model is not limited to this.
Further, be provided with cardan shaft 12, be placed in the propelling screw thread 11 on cardan shaft 12 in extruder barrel 8, the end of cardan shaft 12 is connected with the motor 10 of being located at extruder barrel 8 outsides.By direct-drive motor, design, can effectively save electric energy.
Further, be also provided with hopper 9 on extruder barrel 8, hopper 9 consists of cylindrical section and conical section, and conical section is connected with extruder barrel 8.The hopper of this kind of structure, can make material enter extruder barrel more even.
