Description

Unfired brick pressing machine

The utility model relates to the machinery of processing raw material of brick and tile, particularly soon, two sections moulding prepare the screw pressing machinery of the motor-driven coupling of manpower of adobe at a slow speed.

Original a kind of brick and tile pressing machinery is made of the rotating disk that a plurality of diaphragm capsules are arranged of the friction disc transmission one start screw screw rod punching mechanism on support, column, column top and pressure head, punching mechanism below and gear drive thereof, feed mechanism, drive motors.This press humidity that processes raw material is leather hard, and adobe need not drying can go into the stove roasting, but because the punch forming process that is shaped to of adobe, molding time is short, air in the raw material is discharged insufficient, and the product of burning till have more existing lamination defect, have a strong impact on quality.

Given this, the purpose of this utility model just is to provide a kind of processing leather hard raw material, can realize fast, two sections moulding at a slow speed, makes the pressing machinery that air is fully discharged in its raw material.Another purpose provides a kind of pressing machinery that adopts above-mentioned two sections moulding manufacturing hollow brick blank.

Brick-pressing machine of the present utility model (referring to accompanying drawing), comprise support (1), column on the support (2), moulding on column shaped as frame diaphragm capsule (3), the loading hopper (4) of diaphragm capsule top, with the pressure mechanism (6) of Worm and Worm Gear Driving screw rod (5) and the moulding pressure head (7) of screw rod (5) tip, the motor (9) that links with worm screw (8) transmission, above-mentioned pressure mechanism is installed on the support, the end of worm screw has to drive uses manual turntable (10), screw rod (5) is the multiple thread structure, pressure head is from stretching in the diaphragm capsule of top down, there is lid (11) the diaphragm capsule top, what the front end of lid had a setting pushes away blanket (12), there is the rack and-pinion mechanism that pushes lid and adobe the lid top and drives with handwheel (13), and the side of diaphragm capsule has supporting to transport the platform (14 of adobe and lid, 15).

The eccentric mechanism that the locking lid can be arranged on the above-mentioned column.

The adobe of above-mentioned diaphragm capsule is released can be there to be the blank cutter structure of cutting base device (16) that comprises of cutting base.

The core frame (17) of making hollow brick can be arranged in the above-mentioned diaphragm capsule, and above-mentioned pressure head has the core hole (18) that matches with the core frame.

Brick-pressing machine of the present utility model, from loading hopper raw material is sent into diaphragm capsule, move handwheel,, the lid on the platform is pushed to the close cover mold box 2 in diaphragm capsule top by the rack-and-pinion transmission, compile heart wheel mechanism if install additional, move this mechanism and can lock lid, starter motor makes the screw rod rotation through transmission mechanism and Worm and Worm Gear Driving, pressure head boost fast to certain position, then close power machine, move manual turntable, still rotate through the Worm and Worm Gear Driving screw rod, the pressure head of boosting at a slow speed is pressed into base, unclamp eccentric mechanism then, move handwheel, lid is return platform, restart motor or move manual turntable, pressure head ejects diaphragm capsule with base, moves handwheel, and lid is pushed to the diaphragm capsule top again, rely on the blanket that pushes away of lid front end simultaneously, base is pushed on the opposite side platform, and starter motor is return pressure head, finish the adobe compacting, so adobe is just made in circulation continuously.If the blank cutter structure is set, then can repairs base, or again base be cut into the adobe of general size.During the compacting hollow brick, need in diaphragm capsule, to add the cored frame, and use the pressure head that the core hole is arranged.

Brick-pressing machine of the present utility model has following advantage and positive effect because of it has said structure.

1, the utility model realized fast, two sections moulding at a slow speed, it is the rapid shaping section that starter motor promotes pressure head, and moving manual turntable, to promote pressure head be profiled section at a slow speed, again owing to adopt multiple-threaded screw rod, quick fraction can suitably improve shaping speed, and can shorten pressure head return interval.Air is fully discharged in the Duan Kerang raw material at a slow speed, waits a moment and presses process time unlikely long.Can moulding hang down moisture content, high-ductility, inductile raw material, both overcome the lamination defect of original burnt brick, improve and burnt till quality, improve output again as far as possible.

2, the utility model installs the blank cutter structure additional, but one-shot forming suppresses the neat polylith adobe of periphery.

3, the utility model adds the cored frame and uses corresponding pressure head in diaphragm capsule, can suppress hollow brick blank, if not installing said structure additional then suppresses solid adobe, can suppress solid, hollow two class adobes.

Below, with embodiment and comparative examples accompanying drawing, brick-pressing machine of the present utility model is elaborated again.
