Description

Technical Field

[0001] The invention relates to the technical field of autoclaved aerated concrete block production equipment, in particular to an edge trimming device for autoclaved aerated concrete blocks. Background Art

[0002] Concrete blocks are usually placed in a mold box for forming. However, due to the long-term use of the mold box, some concrete blocks will stick to the inner wall of the mold box or the inner wall of the mold box will be worn, which will cause the surface of the obtained concrete blocks to be rough and uneven. Therefore, in order to obtain a product with a smooth surface, a certain thickness of the concrete surface needs to be cut off;

[0003] Existing cutting equipment uses a taut steel wire to trim concrete blocks, but there are the following problems: first, before the trimming operation is performed on the blocks, the top surface of the cut blocks may be rough and uneven. When the steel wire contacts the top surface of the blocks in the initial stage of trimming, the steel wire may be offset due to contact with the uneven area on the top surface of the blocks, thereby affecting the straightness of the trimmed surface of the blocks after trimming; second, after the trimming is completed, the waste cut from the blocks will be separated from the blocks by special equipment. The waste is separated, and since the cut waste is also a complete block, the waste will be directly poured into the waste collection area after separation. In the process of falling, the waste will be broken from a complete block into several blocks of different sizes. In the process of breaking, the blocks are easy to splash around and generate a lot of dust, which is easy to cause harm to on-site personnel; there is a lack of autoclaved aerated concrete block trimming equipment that can ensure the straightness of the trimming surface of the block and the cut waste will not affect the on-site personnel while using steel wire to trim the blocks.

[0011] Preferably, the end of the slotted member is sharp and the outer side of the slotted member is serrated.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, firstly, the building block to be trimmed is placed on the placing table, the lower end of the steel wire is located just above the trimming area of ​​the building block, and the installation frame is controlled to descend by the electric push rod. When the lower end of the steel wire is about to touch the top surface of the building block, the first motor is controlled to drive the driving plate and the rotating rod to rotate, thereby driving the slide rod to reciprocate in the horizontal direction, thereby driving the two installation rods to reciprocate, so that the steel wire reciprocates in the horizontal direction, and then the steel wire is driven to continue to descend by the electric push rod. The two cooperate with each other to make the steel wire continue to penetrate downward from the top of the building block, and because the steel wire reciprocates in the horizontal direction, the friction between the steel wire and the building block is increased, thereby further facilitating the trimming operation of the building block by the steel wire. When the steel wire is controlled by the electric push rod to move to the bottom of the building block, the trimming work of the building block is completed.

[0014] In the present invention, when the steel wire is reciprocated in the horizontal direction through the transmission of the driving frame, the movement of the driving frame drives the toothed rod to reciprocate in the horizontal direction, thereby driving the two second gears to rotate, and then driving the two connecting wheels to rotate under the transmission of the first gear, thereby driving the steel wire mounted on the two connecting wheels to transmit, and the transmission direction of the steel wire is opposite to its own movement direction, thereby further improving the friction between the steel wire and the building blocks, thereby further improving the edge cutting efficiency of the steel wire on the building blocks.

[0015] In the present invention, as the uneven side of the building block is gradually cut by the steel wire, as the steel wire descends, the second motor is controlled to work, driving the transmission gear directly above the steel wire to rotate, and the upper end of the discharge plate moves downward along the side end of the building block. As the transmission gear rotates, the gears on the transmission gear successively contact and disengage with the lower end of the transmission member, and the cycle repeats. In this process, the striking hammer is driven to strike the cut side of the building block, causing it to gradually break into pieces from a complete piece and fall on the discharge plate, and then fall into the waste box through the conveyance of the discharge plate. Through the above method, the problem of the cut waste being broken into several blocks of different sizes during the process of falling down, and the problem of the blocks splashing everywhere and generating a large amount of dust during the breaking process, causing harm to on-site personnel, is avoided.

[0016] In the present invention, when the steel wire is about to contact the top surface of the block and the slotted part is located on the side of the top surface of the block, the third motor is controlled to drive the slotted gear to rotate, thereby driving the toothed plate and the trigger sleeve away from the steel wire, the first spring contracts, and then the teeth on the slotted gear are separated from the toothed plate, so that the trigger sleeve is reset, and the slotted part is impacted to move toward the top surface of the block. Through the shape of the end of the slotted part and the sawtooth on the outside, a straight groove is opened on the top surface of the block, and then the slotted part is reset under the action of the second spring. At this time, a straight groove for accommodating the steel wire is provided on the top of the block. When the steel wire descends, the block is trimmed in the straight groove, thereby avoiding the problem that the steel wire is easily displaced when it descends due to the uneven top surface of the block, thereby causing the uneven cutting surface of the block.
