Abstract
The invention discloses a machine core of an extruder head and the extruder head, wherein the machine core of the extruder head comprises a machine core body, the machine core body is of a conical structure, the outer diameter of the machine core body is sequentially reduced along the extrusion direction of the extruder head, a groove is formed in one side of the outer side wall of the machine core body, which corresponds to a feed inlet of the extruder head, and the area of the groove is sequentially reduced along the extrusion direction of the extruder head. Compared with the prior art, the groove is formed in one side, corresponding to the feed inlet of the extruder head, of the outer side wall of the machine core body, so that the rubber materials of the machine core body on the two sides of the feed inlet tend to be consistent, the wall thickness of the extruded rubber materials is uniform and consistent, the structure is simple, and the realization is easy.
Description
Technical Field
The invention relates to the technical field of extruders, in particular to a machine core of an extruder head and the extruder head.
Background
The rubber roller is an important part in the spinning drafting device, and is a roller-shaped product which is made of metal or other materials as a core body and is coated with rubber.
In the production process of the rubber roller, rubber on the outer surface of the rubber roller is extruded by an extruder, however, a feed inlet of an extruder head of the existing part of the extruder is arranged on the side wall, so that the flow velocity of the rubber material in a flow channel adjacent to the feed inlet is different from that in a flow channel far away from the feed inlet, the wall thickness of the extruded rubber material is inconsistent, the wall thickness of the rubber material is uneven, and the forming quality of the rubber roller is influenced, so that the problem is urgently solved.
Disclosure of Invention
The present invention is directed to solve the above problems, and an object of the present invention is to provide a movement of an extruder head and an extruder head, so as to solve the above problems in the background art.
The purpose of the invention is realized by the following technical scheme:
the utility model provides an extrude core of aircraft nose, includes the core body, the core body is conical structure, follows the crowded material direction of extruding the aircraft nose, the external diameter of core body steadilys decrease in proper order, one side that corresponds on the lateral wall of core body and extrudes the aircraft nose feed inlet is seted up flutedly, follows the crowded material direction of extruding the aircraft nose, the area of recess steadilys decrease in proper order.
As a preferable scheme of the invention, the depth of the groove is 5 mm-10 mm.
In a preferred embodiment of the present invention, the depth of the groove is 6 mm.
As a preferred scheme of the present invention, the outer diameter of the first end of the movement body is greater than the outer diameter of the second end of the movement body, and the first end of the movement body is connected to a fixed flange.
An extruder head comprises the movement of the extruder head.
Compared with the prior art, the rubber extruder has the beneficial effects that the groove is formed in one side, corresponding to the feed inlet of the extruder head, of the outer side wall of the core body, so that rubber materials on two sides of the feed inlet of the core body tend to be consistent, the wall thickness of the extruded rubber materials is uniform and consistent, the structure is simple, and the realization is easy.
Drawings
Fig. 1 is a schematic view of the structure of a movement of an extruder head.
In the figure:
1. a machine core body; 2. a groove; 3. and (5) fixing a flange plate.
Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the embodiments described herein are illustrative only and are not limiting upon the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a core of an extruder head.
In this embodiment, a core of extruder head, including core body 1, core body 1 is conical structure, follows the crowded material direction of extruder head, the external diameter of core body 1 steadilys decrease in proper order, one side that corresponds the extruder head feed inlet on core body 1's the lateral wall is seted up flutedly 2, follows the crowded material direction of extruder head, the area of recess 2 steadilys decrease in proper order.
Specifically, in this embodiment, the depth of the groove 2 is 6 mm.
It should be noted that, although the depth of the groove 2 is 6mm in the present embodiment, the present invention is not limited thereto, and the depth of the groove 2 may also be 5mm or 10mm or any value therebetween, and the present embodiment is a preferred embodiment of the present invention, and the thickness of the extruded rubber compound is uniform by adopting the present structural design.
Specifically, in this embodiment, the external diameter of the first end of core body 1 is greater than the external diameter of the second end of core body 1, the first end of core body 1 is connected with fixed flange 3 to it is fixed to be convenient for the installation.
Above-mentioned core of extruder head sets up recess 2 through one side that corresponds the extruder head feed inlet on the lateral wall of core body 1, and then makes core body 1 tend to unanimously at the sizing material of feed inlet both sides to make the sizing material wall thickness of extruding even, unanimous, simple structure, easily realization.
The embodiment also discloses an extruder head, which comprises the movement of the extruder head.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims.
Claims (5)
1. The utility model provides an extruder head's core, includes the core body, the core body is conical structure, follows extruder head's crowded material direction, the external diameter of core body subtracts its characterized in that in proper order: one side of the outer side wall of the machine core body, which corresponds to the feed inlet of the extruder head, is provided with a groove, and the area of the groove is gradually decreased along the extruding direction of the extruder head.
2. A movement for an extruder head, according to claim 1, wherein: the depth of the groove is 5 mm-10 mm.
3. A movement for an extruder head, according to claim 2, wherein: the depth of the groove is 6 mm.
