Abstract
The utility model relates to a novel rubber double-layer co-extruding machine head mainly consisting of a machine head body, an outer shunting sleeve, an inner shunting sleeve, a die core sleeve, a die sleeve base, a die core, a middle sleeve, a die sleeve and a connecting sleeve. The innovation points are as follows: the front end of the connecting sleeve is fixedly connected with a telescopic sleeve. The rubber double-layer co-extruding machine head is scientific and reasonable in structure; and by the telescopic sleeve arranged at the front end of the machine head body, the co-extruding machine head can directly extends into the connection end of an upper sealing device when being connected with the upper sealing device on a vulcanizing pipeline, therefore the operation time is effectively shortened and the labor intensity is lowered. Besides, the novel rubber double-layer co-extruding machine head also has the remarkable effects of high matching precision, uneasy deformation and good connection reliability, and the sealing effect of the co-extruding machine head with the upper sealing device is effectively ensured.
Description
Technical field
The utility model belongs to electric wire manufacturing installation field, particularly a kind of new type rubber double-layer coextrusion head.
Background technology
Rubber double-layer coextrusion head is used for production line of electrical wire and cable, is used for coating on running electric wire the double-layer rubber layer.Existing rubber double-layer coextrusion head mainly is made of handpiece body, external shunt cover, interior shunting cover, core rod cover, die sleeve seat, core rod, middle cover, die sleeve and coupling sleeve etc., handpiece body is provided with two liquid rubber charging apertures, front end at handpiece body is installed coupling sleeve, and this coupling sleeve is used for being connected with the upper sealing device of sulfuration pipeline.Liquid rubber is delivered between core rod and the middle cover from handpiece body, and in the ring cavity between middle cover and the die sleeve, along with electric wire walking in core rod, is coated on the electric wire skin continuously, forms the double-layer rubber skin.Former rubber double-layer coextrusion head directly adopts when the coupling sleeve of its front end is connected with upper sealing device to be threaded in operating process, and it is easy to generate alignment error, causes poorly sealedly, causes leaking vapour.And in process of production, the high-temperature gas of sulfuration in the pipeline makes coupling sleeve produce easily and adds thermal deformation, also causes poorly sealed easily and leaks gas.In addition, also there is the extremely inconvenient outstanding problem of operation in existing connection mode, influences operating efficiency, and labour intensity is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy for installation, the new type rubber double-layer coextrusion head of good airproof performance.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of new type rubber double-layer coextrusion head, mainly constitute by handpiece body, external shunt cover, interior shunting cover, core rod cover, die sleeve seat, core rod, middle cover, die sleeve and coupling sleeve, suit external shunt cover, interior shunting cover, core rod cover successively in handpiece body, front end at the core rod cover installs core rod, front end at the external shunt cover installs middle cover, front end inside at handpiece body installs the die sleeve seat, front end inside at the die sleeve seat installs die sleeve, front end at handpiece body installs coupling sleeve, it is characterized in that: the front end at coupling sleeve is fixed with a telescopic.
Advantage of the present utility model and beneficial effect are:
This new type rubber double-layer coextrusion handpiece structure design science is reasonable, by the front end at handpiece body telescopic is set, and when the upper sealing device with the sulfuration pipeline is connected, can directly stretch into the link of upper sealing device, effectively shortens the operating time, reduces labour intensity.And this mechanism also has quality of fit height, not yielding, outstanding effect that connection reliability is good, effectively guarantees the sealing effectiveness of co-extruding machine head and upper sealing device.
Description of drawings
Fig. 1 is structural representation of the present utility model (cutaway view).
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of new type rubber double-layer coextrusion head mainly is made of handpiece body 2, external shunt cover 3, interior shunting cover 4, core rod cover 6, die sleeve seat 8, core rod 13, middle cover 12, die sleeve 9 and coupling sleeve 11.Handpiece body is provided with two liquid rubber imports 1,7.Suit external shunt cover, interior shunting cover, core rod cover successively in handpiece body are set with to adjust between core rod cover and interior shunting cover and overlap 5.Front end at core rod cover installs core rod, installs middle cover at the front end of external shunt cover, installs the die sleeve seat in the front end inside of handpiece body, installs die sleeve in the front end inside of die sleeve seat, installs coupling sleeve at the front end of handpiece body.The innovation part of this rubber co-extruding machine head is: at the coaxial telescopic 10 that is fixed with of the front end of coupling sleeve, this telescopic is used for being connected and fixed with the upper sealing device of sulfuration pipeline.This rubber co-extruding machine head can be realized quick connection, shortens the operating time, reduces labour intensity, guarantees connection reliability simultaneously, guarantees sealing effectiveness.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the present invention and claims, various replacements, variation and modification all are possible, therefore, scope of the present invention is not limited to embodiment and the disclosed content of accompanying drawing.
