Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses extruder that can change sealed raw materials internal diameter size of gluing. Referring to fig. 1 and 2, an extruder capable of changing the inner diameter dimension of a sealant raw material comprises a screw barrel 1, a screw 2 and a machine head 3. The screw barrel 1 is provided with a feed inlet communicated with the interior of the screw barrel 1, and rubber enters the screw barrel 1 through the feed inlet; the screw 2 is arranged in the screw barrel 1, one end of the screw 2 is connected with a power source 16 for driving the screw 2 to rotate, and the screw 2 is driven by the power source 16 to stir and rotate the rubber in the screw barrel 1; the head 3 is screwed to the end of the screw barrel 1 far away from the power source 16, and rubber discharged from the screw barrel 1 passes through the head 3 to determine the outer diameter of the rubber.

Referring to fig. 1, a tool rest 13 is further disposed at the head 3, a hydraulic press 15 is mounted on the tool rest 13, and an arc knife 14 for cutting rubber discharged from the head 3 is further connected to an output end of the hydraulic press 15. The rubber extruded from the machine head 3 enters the cutter frame 13 and is positioned below the arc surface cutter 14, and the arc surface cutter 14 cuts the rubber through the action of the hydraulic machine 15 to manufacture the rubber meeting the requirements of finished products.

Referring to fig. 2 and 3, a molding assembly 4 for changing the inner diameter of the molded rubber can be detachably mounted at one end of the screw rod 2 at the machine head 3, and a worker can replace the molding assembly 4 so as to manufacture the inner diameter of the rubber meeting the requirements of a finished product. The molding assembly 4 comprises a molding head 5, a splice 6 and a stopper 7. The molding heads 5 have various types, and the molding heads 5 of different types have different outer diameters for selection by workers, but all the molding heads 5 of the types are provided with connecting grooves 17 having the same inner diameter and into which the screw rods 2 are inserted. Splice 6 sliding connection is between screw rod 2 and shaping head 5, stops 7 and can insert to screw rod 2 inside and carry on spacingly to splice 6, makes splice 6's both ends be located shaping head 5 and screw rod 2 inside respectively. When the blocking piece 7 is in contact with the splicing piece 6, along with the gradual penetration of the blocking piece 7 in the screw rod 2, the splicing piece 6 starts to move towards one end of the forming head 5 until the length of the splicing piece 6 in the screw rod 2 reaches the limit, the splicing piece 6 cannot slide at the moment and keeps the state that two ends of the splicing piece are respectively positioned in the forming head 5 and the screw rod 2, so that the fixing effect on the forming head 5 and the screw rod 2 is achieved.

Referring to fig. 3, a limiting rod 18 integrally formed with the molding head 5 is further fixedly connected inside the connecting groove 17, a limiting groove 19 for the limiting rod 18 to insert is formed in the end portion of the screw 2, and when the limiting rod 18 contacts with the groove bottom of the limiting groove 19, it is described that the splice 6 can slide in the molding head 5 under the driving of the stopper 7. In addition, in the present embodiment, two limiting rods 18 are provided, the two limiting rods 18 are disposed oppositely, and a limiting groove 19 is also formed corresponding to the limiting rod 18 for the corresponding limiting rod 18 to be inserted.

Referring to fig. 3 and 4, the molding head 5 includes a horizontal portion 9 and an inclined portion 8 formed integrally with the horizontal portion 9, and the outer diameter of the molding head 5 depends on the outer diameter of the horizontal portion 9. The outside diameter of the inclined portion 8 of the forming head 5 is gradually reduced in a direction away from the lateral portion 9, and the connecting groove 17 penetrates both the inclined portion 8 and the lateral portion 9. The screw 2 firstly passes through the connecting groove 17 of the inclined part 8 and then enters the connecting groove 17 of the transverse part 9, and the rubber in the screw barrel 1 firstly contacts with the inclined part 8 and then enters the transverse part 9, so that the inclined part 8 is convenient for the rubber to smoothly pass to the transverse part 9.

Referring to fig. 3 and 4, when the blocking member 7 is inserted into the splicing member 6, a guiding end surface 10 is further disposed on a surface of the blocking member 7 facing the splicing member 6, and when the blocking member 7 is further pushed after the blocking member 7 contacts the guiding end surface 10, the end of the splicing member 6 can be smoothly guided to be inserted into the molding head 5 by the inclined surface of the guiding end surface 10. The outer side wall of the blocking piece 7 is also bonded with an anti-slip layer 12, friction force between the blocking piece 7 and the interior of the screw rod 2 is increased through the anti-slip layer 12, so that the blocking piece 7 is not easy to fall out of the screw rod 2, and the stability of the splicing piece 6 is enhanced. When blockking piece 7 and can't continue to remove in screw rod 2, the one end that keeps away from the terminal surface of leading of blockking piece 7 this moment still is located the screw rod 2 outside, and this tip external diameter has still evenly seted up a plurality of anti-skidding lines 11, and when the staff will change forming head 5 again, can play the effect of conveniently pulling out in blockking piece 7 follow screw rod 2 through anti-skidding line 11.

The embodiment of the application discloses the implementation principle of extruder that can change sealed glue raw materials internal diameter size does: the staff establishes the shaping head 5 cover of different external diameters outside screw rod 2, later promotes to blockking piece 7 to drive splice 6 and realize the relative fixed connection of shaping head 5 and screw rod 2, thereby reach the purpose of the bolt of production different internal diameters.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
