Description

Vertical foxing extruder

Technical Field

The utility model relates to a foxing extrusion equipment, concretely relates to vertical foxing extruder for producing double-colored compound foxing.

Background

The rubber shoe surrounding strip is a rubber flat strip which is attached to the side face of the rubber shoe and surrounds the sole for a circle and has a decoration function, and the rubber shoe surrounding strip is generally formed by extruding through a surrounding strip extruder. In order to complete the production of the double-color composite foxing, the prior foxing extruder generally comprises a main screw extruder and an auxiliary screw extruder, the discharge ports of the two screw extruders are connected with the same extrusion die head, the defect is that the two screw extruders are installed in parallel, the discharge port of the auxiliary screw extruder can be connected with the side feed port of the extrusion die head through a 90-degree steering elbow, the discharge resistance of the auxiliary screw extruder is large, and in addition, the steering elbow is not easy to clean, so the material is easy to block at the steering elbow, the discharge of the auxiliary screw extruder is not uniform, the extrusion of the extrusion die head is not uniform, and the thickness of a foxing product is not uniform; in addition, in the surrounding bar extruder in the prior art, the extrusion die head has the problems that the die core is not easy to detach when the die core is replaced, and the sealing reliability of the inner cavity of the die sleeve is not easy to ensure after the die core is installed, so that the uncertainty is brought to the normal production of the surrounding bar extruder.

Disclosure of Invention

Not enough to prior art existence, the utility model aims at providing a can avoid the putty, realize that the die head extrudees evenly, guarantees that foxing product thickness is unified, can realize the quick replacement of mold core in addition, makes the mold core change in being dismantled to guarantee the sealed reliable vertical foxing extruder of mold core installation back mold core inner chamber.

The utility model adopts the following technical proposal to complete:

vertical foxing extruder, including main screw extruder, vice screw extruder and extrusion die, extrusion die is equipped with the discharge gate of main feed inlet and main screw extruder and meets, and the discharge gate that is equipped with side feed inlet and vice screw extruder meets its characterized in that: the auxiliary screw extruder is vertically installed, the auxiliary screw extruder is located above the extrusion die head, a discharge port of the auxiliary screw extruder is linearly communicated with the side feed port, and the side feed port is located in the top direction of the extrusion die head.

Above-mentioned technical scheme's vertical foxing extruder, the vice screw extruder of special design is vertical installation, makes vice screw extruder's discharge gate and extrusion die's side feed inlet straight line communicate with each other, has just avoided 90 degrees to turn to the setting of elbow when the extrusion production of double-colored foxing like this, and vice screw extruder's ejection of compact resistance is little, and the ejection of compact of the vice screw extruder that the putty leads to also can not appear is inhomogeneous, and then realizes that the extrusion of die head is even, guarantees that foxing product thickness is unified.

Preferably, the extrusion die head comprises a die sleeve and a die core, the die core is positioned in an inner cavity of the die sleeve and is compressed and fixed by a compression sleeve, the compression sleeve is screwed in an inner hole of a threaded sleeve, the threaded sleeve is mutually attached to the front end surface of the die sleeve and is clasped and locked by an upper locking semi-ring and a lower locking semi-ring. The die sleeve inner chamber has interior trompil and outer trompil, and main feed inlet is located the rear side direction that outer trompil was kept away from to trompil in the interior, and the side feed inlet is located the top direction of interior trompil, and the aperture of outer trompil is greater than interior trompil, the mold core comprises preceding middle and back three-section, and preceding mold core external diameter is minimum, and middle mold core external diameter is the biggest and big than the trompil aperture in the die sleeve, and back mold core is located trompil in the die sleeve, and middle mold core and preceding mold core are located the trompil outside the die sleeve, and middle mold core cuts off the intercommunication between the trompil and the outer trompil in the die sleeve, and the preceding terminal surface of preceding mold core is overhanging to stretch out the outer trompil of die sleeve, compress tightly the preceding terminal surface of cover to the position at middle mold core of mold core. The upper and lower locking half rings are separated from each other by a certain distance in the up-down direction, the rear ends of the upper and lower locking half rings are hinged on the fixed seat, the front ends of the upper and lower locking half rings are respectively hinged with one ends of the short connecting rod and the long connecting rod, the other ends of the short connecting rod and the long connecting rod are hinged with each other, and the short connecting rod is fixedly connected with the locking operation handle.

After the technical scheme is adopted, the mold core is composed of the front section, the middle section and the rear section, when the mold core is tightly pressed and fixed in the inner cavity of the mold sleeve by the pressing sleeve, the middle section of the mold core can separate the communication between the inner opening and the outer opening of the mold sleeve, so that the inner sealing of the inner cavity of the mold sleeve is reliable after the mold core is installed, and the surrounding strip rubber material is prevented from entering the outer opening of the mold sleeve; in addition, the front end surface of the mold core extends outwards to extend out of the outer opening of the mold sleeve, and when the threaded sleeve is detached, the mold core is partially exposed out of the mold cavity of the mold sleeve, so that the mold core is easier to take out, and the mold core is greatly convenient to replace quickly. The specific operation process is as follows: during installation, firstly, a mold core is placed in an inner cavity of a mold sleeve, then the threaded sleeve is attached to the front end face of the mold sleeve, then a locking operation handle is pulled to enable the upper locking semi-ring and the lower locking semi-ring to be mutually buckled, the mold sleeve and the threaded sleeve are locked, and finally the compression sleeve is screwed to compress and fix the mold core; when the mold core is disassembled, the mold core is compressed by the compression sleeve, then the locking operation handle is pulled reversely to loosen the upper and lower locking semi-rings, then the threaded sleeve is disassembled, and then the mold core is taken out.
