Extruder quick clamp glue supply head

Abstract

The invention discloses a quick clamping glue supply machine head of an extruder. The quick clamping glue supply machine head comprises an extrusion machine head connected with a pin machine barrel through a rotating arm device; a locking device is arranged between the extrusion machine head and the pin machine barrel; the rotating arm device comprises a double-connecting rod mechanism composed of two swing rods; one ends of the two swing rod are mutually hinged; the other ends of the two swing rods are respectively hinged with the extrusion machine head and the pin machine barrel; the locking device comprises a bolt and a slot washer; the bolt is arranged in a bolt penetrating hole in the extrusion machine head; the diameter of the bolt penetrating hole is more than the screw head of the bolt; the slot washer is clamped on a screw rod between the screw head of the bolt and the extrusion machine head; and the diameter of the slot washer is more than that of the bolt penetrating hole. According to the quick clamping glue supply machine head, the original single-rotating arm mechanism is replaced by the double-connecting rod mechanism, so that the extrusion machine head not only can axially move but also can rotate, and has high manoeuvring characteristics; compared with a C-type clamping ring, the quick clamping glue supply machine head is relatively high in clamping speed, light in weight and low in cost.

Description

(1) Technical field: [0001] The invention relates to an extruder for rubber product production, in particular to a fast clamping and supplying head of the extruder. (2) Background technology: [0002] The rubber supply head of the extruder is a commonly used head of the pin barrel cold-feed extruder. The head is generally connected to the pin barrel through a rotating arm, but the rotating arm is generally a single rotating arm, and the head can only Rotate, can not move in a straight line away from the pin barrel, which is not conducive to operations such as glue removal and die plate replacement. [0003] In addition, the locking of the machine head and the pin barrel is usually in the form of a C-shaped clamp ring. Because the C-shaped clamp ring has a complicated structure and a large size, the cost of the machine head increases. (3) Contents of the invention: [0004] The purpose of the present invention is to propose an extruder head that leaves the pin barrel by mo...

[0002] The rubber supply head of the extruder is a commonly used head of the pin barrel cold-feed extruder. The head is generally connected to the pin barrel through a rotating arm, but the rotating arm is generally a single rotating arm, and the head can only Rotate, cannot move in a straight line away from the pin barrel, which is not conducive to operations such as glue removal and die plate replacement

[0003] In addition, the locking of the machine head and the pin barrel is usually in the form of a C-shaped clamp ring. Due to the complex structure and large size of the C-shaped clamp ring, the cost of the machine head will increase.
