Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a crowded frock altogether, including the support base 1 that is used for placing, three top that supports base 1 is fixed mounting respectively has first extruder 2, second extruder 3 and third extruder 4, the one end of first extruder 2, the one end of second extruder 3 and the one end of third extruder 4 all are provided with feed hopper 5, the one end of first extruder 2, the one end of second extruder 3 and the one end of third extruder 4 all are provided with crowded mechanism altogether, crowded mechanism is including crowded frock 6 altogether, the inside of crowded frock 6 that altogether slides and pegs graft there is basic unit's section bar 7 altogether, the surperficial inoxidizing coating that forms of crowded frock 6 is crowded altogether extruded through crowded mechanism realization altogether to basic unit's section bar 7 all around.

In order to control the automatic forming and sealing inside the co-extrusion tool 6, a sealing groove 15 is formed in an output groove at one end of the co-extrusion tool 6, a sealing gasket 16 is fixedly arranged on the inner wall of the sealing groove 15, the surface of the sealing gasket 16 and the peripheral surface of the base layer section bar 7 are mutually extruded, and therefore the effect of utilizing the surface of the sealing gasket 16 to extrude the surface of the base layer section bar 7 to enable the sealing to be generated inside the co-extrusion tool 6 and facilitate the forming operation is achieved.

For 7 contour machining of basic unit section bar surface automatic formation inoxidizing coating simultaneously, it includes first inoxidizing coating 8 and second inoxidizing coating 9 to set up the inoxidizing coating, first inoxidizing coating 8 realizes through second extruder 3 that automatic extrusion material enters into the action of the surface adhesion of crowded frock 6 inside and basic unit section bar 7 altogether, and then reached in 7 contour machining of basic unit section bar in crowded frock 6 inside automatic surface shaping inoxidizing coatings that make altogether, avoid carrying out the spraying inoxidizing coating alone behind the 7 shaping of current basic unit section bar, can not make basic unit section bar 7 and inoxidizing coating form wholly, the easy wearing and tearing of spraying drop, thereby through this device a shaping reinforcing life.

For basic unit's section bar 7 is automatic in the inside automatic conveying of crowded frock 6 altogether after 2 extrusion moulding of first extruder, it realizes through third extruder 4 that automatic extrusion material enters into crowded frock 6 inside and basic unit's section bar 7 surface adhesion motion to set up second inoxidizing coating 9, conveyer trough 10 has been seted up on the surface of crowded frock 6 altogether, the feed end of conveyer trough 10 is corresponding with the discharge end of first extruder 2, and then reached and set up conveyer trough 10 and make the basic unit's section bar 7 of first extruder 2 extrusion moulding at the inner wall sliding effect of conveyer trough 10.

The base section bar 7 is input into the co-extrusion tool 6 and is internally corresponding, the feeding end of the co-extrusion tool 6 is set to be corresponding to the discharging end of the first extruder 2, the base section bar 7 is extruded through the first extruder 2 to realize automatic forming, the extruded base section bar enters the inside inserting operation of the co-extrusion tool 6, the feeding end of the co-extrusion tool 6 is corresponding to the discharging end of the first extruder 2, and the base section bar 7 extruded by the first extruder 2 conveniently enters the inside end of the co-extrusion tool 6.

In order to control the material of the protective layer to enter the co-extrusion tool 6 for use in a matched manner, a first forming groove 11 and a second forming groove 12 are respectively formed in the inner top wall and the inner bottom wall of the conveying groove 10, a first feeding pipe 13 is fixedly communicated with the inner top wall of the first forming groove 11, the top of the first feeding pipe 13 is fixedly communicated with the discharging end of the second extruder 3, a second feeding pipe 14 is fixedly communicated with the inner bottom wall of the second forming groove 12, the surface of the second feeding pipe 14 is L-shaped, the feeding end of the second feeding pipe 14 is fixedly communicated with the discharging end of the third extruder 4, and therefore the effect that the surface of the base section 7 is in contact with the protective material inside the co-extrusion tool 6 to be integrally formed in the slow movement of the conveying groove 10 is achieved.

Reach the plastics door frame cardboard when extrusion moulding through setting up crowded mechanism altogether, carry out simultaneous extrusion moulding and surface protection layer integrated into one piece operation through crowded frock 6 altogether, and then the surface formation of control inoxidizing coating and basic unit's section bar 7 is whole, the life of section bar has been strengthened, the work efficiency of production has been improved, the cost of many times processing has been reduced, and avoid the current mode formation inoxidizing coating of adopting the spraying alone to lead to wearing and tearing to cause in the use to drop, reduce the aesthetic property that life influences the outward appearance.

The working principle is as follows: the material is added from the feeding hopper 5 to the first extruder 2, the second extruder 3 and the third extruder 4, the first extruder 2 is started to work, the material forming base section bar 7 is moved out of the first extruder 2 and enters the coextrusion tool 6 to be inserted into the conveying groove 10, meanwhile, the second extruder 3 and the third extruder 4 control the material of the protective layer to flow into the coextrusion tool 6 to be in surface contact with the base section bar 7 under the forming pressure of the second extruder 3 and the third extruder 4 to form the first protective layer 8 and the second protective layer 9, the integral forming is carried out, the surface extrusion sealing gasket 16 is moved out from the sealing groove 15, and the coextrusion tool 6 is internally sealed.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
