Automatic blank overturning device of blank stacking machine

Abstract

The invention provides an automatic blank overturning device of a blank stacking machine. The device comprises a front end conveying device, a back end conveying device and a passive overturning bracket roller; a roller of the passive overturning bracket roller realizes passive fixed-axis 90-degree intermittent revolving movement through a pure mechanical ratchet mechanism; L-shaped bracket platforms poked by inertia force and overturned along with a roller body are fixedly mounted at the northeast, northwest, southwest and southeast angles of the roller are fixedly mounted in a manner of central symmetry; when the bracket platforms are intermittently overturned and deflected by 90 degrees, adobes are driven to overturn by 90 degrees in the brick hole directions; and after the adobes are rotated along with the bracket platforms from one side of the roller to the other side, the overturned adobes are conveyed and transferred by the back end conveying device. The device is simple in structure, economical, practical and efficient in blank overturning, saves the manpower, the time and the power, and is more suitable for popularization and application.

Description

technical field [0001] The invention specifically relates to a new type of porous brick. Due to the needs of the firing process in the stacking process, the hollow brick hole must be turned from the left and right direction to the up and down direction, which is beneficial to fully obtain the brick along the flame in the kiln. Roasting, to ensure the quality of its firing, more efficient, labor-saving, and power-saving automatic billet turning device. Background technique [0002] In recent years, under the encouragement and guidance of national industrial policies, my country's brick and tile production enterprises have realized the transformation from clay raw materials to industrial solid waste raw materials such as coal gangue, fly ash, urban construction waste, shale, and river pond silt. In order to reduce the weight of bricks and facilitate construction, brick and tile manufacturers have designed hollow bricks with multiple holes and large holes. On the basis of reduc...

Problems solved by technology

The disadvantages are: 1. The combined use of several cylinder actuators leads to complex equipment structure, high cost, and inconvenient popularization; 2. The billet turning action must be completed by the cylinder first clamping the billet, then turning the billet, and then clamping the billet after turning the billet The operation process of lifting and resetting, the completion of the blank turning action is labor-intensive and time-consuming, which affects the production efficiency; 3. The continuity between the various mechanisms of the existing blank turning device and the continuity between the turning mechanism and other supporting devices is put forward. Once a certain part If a failure occurs, the entire system will be affected, the risk of equipment failure is high, and maintenance is not easy
