Changing device for molds for building block forming machine

Abstract

The invention discloses a changing device for molds for a building block forming machine. In the changing device, fixed shaft seats (7) are fixed on the upper part of a palletizing machine (1) through a connecting base (6), a rotating vertical shaft (8) is sleeved in a pressure bearing (10) arranged in the fixed shaft seats (7), the upper part of the rotating vertical shaft (8) is sleeved with a rotating shaft housing (9), the inner end of a hoisting arm (11) is arranged between the upper and lower fixed shaft seats (7), the outer end of the hoisting arm (11) is connected with the rotating shaft housing (9) through a diagonal draw bar (12), and an outer end hoisting pulley (13) is connected with a pulley hook (15) through a steel rope (14). In normal time, the hoisting arm (11) is rotated and tightly attached to the plane of the palletizing machine (1), but is rotated to a position in front of a building block forming machine (3) when a mold (M) is to be changed, so that the pulley hook (15) can first hook the mold (M) and drive the hoisting arm (11) to rotate on the rotating main shaft (8) to remove the mold (M) from a main machine, and then hook a new mold (M) and drive the hoisting arm (11) to rotate on the rotating main shaft (8) to place the new mold (M) on a specific position of the building block forming machine (3). The changing device has the advantages of quick change, high working efficiency and high safety.

Description

technical field [0001] The invention relates to a block forming machine, in particular to a replacement method of a block mould. Background technique [0002] At present, unburned brick machines and block forming machines use waste brick slag, cement slag, and slag to press blocks, which play a very good role in protecting cultivated land, saving energy, reusing waste, and preventing environmental pollution. Unburned bricks and masonry Blocks are used more and more widely. According to the different needs of users, the model and specification of the production blocks are determined, and various blocks are produced by changing the mold. Especially for large-scale automatic block forming machines, the blocks to be produced have different specifications and many varieties, and the molds often need to be replaced to meet the requirements of block production. The mold is made of steel, which is generally heavy. The weight of the upper mold and the lower mold is about 1.5-2 tons....

AI Technical Summary

Problems solved by technology

The mold is made of steel, which is generally heavy. The weight of the upper mold and the lower mold is about 1.5-2 tons. Moreover, for the convenience of production, the installation of the block forming machine and supporting facilities is relatively compact and the space is narrow. Replacing the mold is not only time-consuming and laborious, but also ext
