Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 , 2 , 3, the present invention provides a rubber extrusion compound head locking mechanism, including a head base 9 and a top head 8 and a bottom head 10 hingedly connected to the top and bottom of the head base 9 , the upper and lower parts of the left and right sides of the machine head seat body 9 are respectively hinged to the lock doors 1 on the left and right sides through column pins 7, and the opening and closing hydraulic cylinders 11 on the left and right sides are hinged on the machine head seat respectively. The left and right middle parts of the body 9, the piston rods of the opening and closing hydraulic cylinders 11 are linked with the hinges of the corresponding lock door 1, and the lock door 1 is rotated around the column pin 7 by pulling and pushing the lock door 1, thereby realizing the opening and closing of the compound machine ...

Abstract

The invention provides a composite rubber extruder head locking mechanism. Locking hydraulic cylinders push piston rods to stretch and retract to drive wedge-shaped locking blocks to move front and back, and then locking or unlocking of a composite extruder head is achieved. Moreover, locking holding depends on mechanical self-locking of locking surfaces during normal extrusion operation. Through the modes of swing opening and closing of a lockable door and locking of the wedge-shaped blocks, the structure is simplified, cost is lowered, operation is facilitated, no impact is produced during operation, and the wedge-shaped blocks are free of bending stress during work.

Description

technical field [0001] The invention relates to the field of rubber processing machinery and equipment, in particular to a locking mechanism for rubber extruding compound head. Background technique [0002] Rubber composite extruders have been widely used in domestic and foreign tire industries and have a growing trend. Moreover, with the needs of the development of tire manufacturing technology, composite extrusion is also developing from two-compound, three-compound to four-compound, five-compound or more compound. The compound die is a key component of the compound extruder, and the locking mechanism is an important structure of the compound die, which greatly affects the sealing effect, service life and operating efficiency of the parting surface of the compound die. From the birth of the rubber compound extruder to the present, the locking technology of the compound head has been continuously developing. [0003] The Chinese patent with the application number 20051013...
