Abstract
The invention discloses a vacuumizing system in a rubber model pre-forming machine, relating to a vacuumizing device. The system comprises a material cylinder and a vacuum pump, wherein the material cylinder and the vacuum pump are connected through a vacuum suction pipe. The system is characterized in that a lifting valve is arranged on the material cylinder; one end of the lifting valve is connected to the vacuum suction pipe; an electromagnetic valve is connected to the vacuum pump; a silencer is connected to the electromagnetic valve; and a vacuum meter is arranged on the vacuum suction pipe. The system disclosed by the invention is novel in structure and convenient to use and has a good vacuumizing effect. Furthermore, the inner cavity of the material cylinder can be closed by the lifting valve so that a pipeline is prevented from being blocked by glue stock.
Description
Technical field
The present invention relates to vacuum extractor, be specifically related to pumped vacuum systems in a kind of rubber cast preforming machine.
Background technology
Rubber is divided into natural rubber and synthetic rubber.Natural rubber is mainly derived from para ruber, when the epidermis of this rubber tree is severed, will flow out milky juice, is called latex, latex through cohesion, washing, moulding, be drying to obtain natural rubber.Synthetic rubber is made by artificial synthesis, adopts different raw materials can synthesize different types of rubber.Rubber (rubber product) refers to that with natural and synthetic rubber be the activity of the various rubbers of raw material production, also comprises the rubber that utilizes scrap rubber to produce again.Rubber industry is one of important foundation industry of national economy.It not only provides daily life indispensable light industry rubber product such as daily, medical for people, and to heavy industry such as digging, traffic, building, machinery, electronics and new industry various rubber system production equipments or rubber components is provided.It is thus clear that the product category of rubber industry is various, the back is very wide to industry.Be used for the compound blank that various annulars, rectangle and other shaped articles of rubber cast production usefulness use at present and all will use preforming machine; Must guarantee that barrel and head inside do not have air before cutting sizing material squeezing; To guarantee that sizing material inside does not produce bubble; But the vacuum extractor that is used in the prior art on the preforming machine is rarely found, can not satisfy the production needs.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of structure letter, vacuumizes pumped vacuum systems in the effective rubber cast preforming machine.
Technical problem to be solved by this invention adopts following technical scheme to realize,
Pumped vacuum systems in the rubber cast preforming machine; Comprise barrel and vavuum pump, said barrel is connected through vaccum suction pipe with vavuum pump, it is characterized in that: said barrel is provided with lift valve; Said lift valve one end connects vaccum suction pipe, is connected with magnetic valve on the said vavuum pump.
Be connected with silencer on the said magnetic valve.
Said vaccum suction pipe is provided with a vacuum meter.
The invention has the beneficial effects as follows: structure of the present invention is provided with novelty, vacuumizes effectively, easy to use, and lift valve can play closing function to the barrel inner chamber, prevents the sizing material blocking pipe.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, pumped vacuum systems in the rubber cast preforming machine comprises barrel 5 and vavuum pump 6; Barrel 5 is connected through vaccum suction pipe 7 with vavuum pump 6; Barrel 5 is provided with lift valve 2, and lift valve 2 one ends connect vaccum suction pipe 7, are connected with magnetic valve 4 on the vavuum pump 6; Be connected with silencer 3 on the magnetic valve 4, vaccum suction pipe 7 is provided with a vacuum meter 1.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
