Description

Technical Field

[0001] This utility model relates to the field of concrete block processing technology, specifically to a cutting device for autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a new type of building material. They are made by reacting cement, lime, sand, gypsum, and foaming agents under high temperature and pressure, resulting in lightweight, porous concrete blocks with excellent thermal insulation and sound insulation properties. They are commonly used in building components such as walls, floors, and roofs, and require cutting equipment for processing.

[0003] As disclosed in the patent announcement CN216139140U, a concrete block cutting device includes a base, an infeed platform and an outlet platform above the base, and a cutting assembly between the infeed platform and the outlet platform. The cutting assembly includes a cutting blade, a rotating shaft, a support frame, and a drive component for rotating the rotating shaft. The beneficial effects of this invention are as follows: the chute moves laterally along the slide rail, thereby driving the support frame to move laterally, and the support frame drives the cutting blade to move laterally, thus achieving the cutting of wider concrete blocks.

[0004] Although the aforementioned patent can achieve the cutting of wider concrete blocks, it uses drive rollers to transport the concrete blocks. If the length of the cut concrete block is less than the distance between the two drive rollers, the two cut concrete blocks cannot be effectively output. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for autoclaved aerated concrete blocks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting device for autoclaved aerated concrete blocks, comprising:

[0008] A base plate is provided with belt conveyors horizontally installed on both upper sides of the base plate, and support legs connected to the base plate are provided at the four corners of the bottom of the belt conveyors.

[0009] A lifting plate is movably arranged between the two belt conveyors, and a material-lifting mechanism is arranged between the bottom plate and the lifting plate;

[0010] A lifting frame is movably installed between the upper ends of the two belt conveyors. A cutting machine is installed in the middle of the inner side of the lifting frame, and a spraying mechanism is installed on one side of the lifting frame.

[0011] Preferably, the top material mechanism includes a lifting cylinder, which is symmetrically arranged at both ends of the middle part of the bottom plate. The output shaft of the lifting cylinder is fixedly connected to the lifting plate, and a trapezoidal platform is provided at the top center of the lifting plate.

[0012] Preferably, the spraying mechanism includes a nozzle, which is installed through the inside of one side of the lifting frame. One end of the nozzle is fixedly connected to a pipe joint through the lifting frame, and a splash guard is provided on the upper outside of the lifting frame.

[0013] Preferably, a side frame is provided between the outer sides of the two belt conveyors on the same direction, and a second lifting cylinder is fixedly installed at the bottom middle part of the side frame, and the output shaft of the second lifting cylinder is fixedly connected to the lifting frame.

[0014] Preferably, guide rods are provided on both sides of the lower part of the lifting frame, and guide grooves matching the guide rods are provided on both sides of the side frame.

[0015] Preferably, the splash guard has a semi-circular structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This is a cutting device for autoclaved aerated concrete (AAC) blocks. After cutting, because the trapezoidal platform has a trapezoidal structure, narrow at the top and wide at the bottom, the two separate AAC blocks will slide towards each other. At this time, the belt conveyors on both sides are started, so that the two belt conveyors convey in opposite directions. The belt conveyors drive the sliding AAC blocks forward. Then, the end of the AAC block near the trapezoidal platform slides down the inclined surface of the trapezoidal platform until it is completely attached to the belt conveyor. In this way, the belt conveyors at both ends can output the cut AAC blocks separately without being affected by the length of the concrete blocks.

[0018] 2. This device for cutting autoclaved aerated concrete blocks supplies cold water to the pipe joint via an external cold water pump during cutting, and then sprays the cutting head of the cutting machine through nozzles. This can cool the cutting head and prevent dust from splashing during cutting. The water generated during spraying is blocked by a splash guard. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A cutting device for autoclaved aerated concrete blocks includes a base plate 1. Belt conveyors 2 are horizontally arranged on the upper ends of both sides of the base plate 1. Support legs 3 connected to the base plate 1 are arranged at the four corners of the bottom end of the belt conveyors 2. A lifting plate 4 is movably arranged between the two belt conveyors 2. A material-lifting mechanism is arranged between the base plate 1 and the lifting plate 4. The material-lifting mechanism includes a lifting cylinder 7. The lifting cylinder 7 is symmetrically arranged at both ends of the middle part of the base plate 1. The output shaft of the lifting cylinder 7 is fixedly connected to the lifting plate 4. A trapezoidal platform 8 is arranged at the top center of the lifting plate 4. A side frame 12 is arranged between the outer sides of the two belt conveyors 2 on the same side. A lifting cylinder 13 is fixedly installed at the bottom center of the side frame 12. The output shaft of the lifting cylinder 13 is fixedly connected to the lifting frame 5. Guide rods 14 are arranged on both sides of the lifting frame 5. Guide grooves 15 matching the guide rods 14 are arranged on both sides of the side frame 12.

[0027] In this embodiment, because it has a trapezoidal structure, narrow at the top and wide at the bottom, the two separate autoclaved aerated concrete blocks will slide towards the opposite side. At this time, the belt conveyors 2 on both sides are started, so that the conveying directions of the two belt conveyors 2 are opposite. The belt conveyors 2 drive the sliding autoclaved aerated concrete blocks forward. At this time, the end of the autoclaved aerated concrete block near the trapezoidal platform 8 slides down the inclined surface of the trapezoidal platform 8 until it is completely attached to the belt conveyor 2. In this way, the belt conveyors 2 at both ends can output the cut autoclaved aerated concrete blocks separately without being affected by the length of the concrete blocks.

[0028] like Figure 4 As shown, a lifting frame 5 is movably installed between the upper ends of the two belt conveyors 2. A cutting machine 6 (consisting of a drive motor and a cutting head, the drive motor controls the cutting head to rotate at high speed to perform cutting, wherein the drive motor is located on the back of the lifting frame 5) is installed in the middle of the inner side of the lifting frame 5. A spraying mechanism is installed on one side of the lifting frame 5. The spraying mechanism includes a nozzle 9. The nozzle 9 is installed through the inside of one side of the lifting frame 5. One end of the nozzle 9 passes through the lifting frame 5 and is fixedly connected to a pipe joint 10 (which can be connected to an external water pump using a corrugated pipe). A splash guard 11 is installed on the upper outer side of the lifting frame 5. The splash guard 11 has a semi-circular structure.

[0029] In this embodiment, during cutting, cold water is supplied to the pipe joint 10 by an external cold water pump, and then sprayed onto the cutting head of the cutting machine 6 through the nozzle 9. This can cool down the cutting head and prevent dust from splashing during cutting. The water generated during spraying is blocked by the splash guard 11.

[0030] Working principle: During processing, two belt conveyors 2 transport autoclaved aerated concrete (AAC) blocks. During cutting, both belt conveyors 2 are shut off, and then lifting cylinder 2 13 is activated. Lifting cylinder 2 13 drives the lifting frame 5 to descend, and the cutting machine 6 is started. The cutting machine 6 rotates at high speed and descends to cut the AAC blocks located on the trapezoidal platform 8. After the AAC blocks are cut, lifting cylinder 1 7 is activated, which drives the lifting plate 4 to lift the trapezoidal platform 8. After the trapezoidal platform 8 is lifted, due to its trapezoidal structure (narrower at the top and wider at the bottom), the two separated AAC blocks will slide towards opposite sides. At this time, the belt conveyors on both sides are activated. The conveyor 2 causes the two belt conveyors 2 to convey in opposite directions. The belt conveyors 2 drive the sliding autoclaved aerated concrete blocks forward. At this time, the autoclaved aerated concrete blocks near the trapezoidal platform 8 slide down the inclined surface of the trapezoidal platform 8 until they are completely attached to the belt conveyor 2. In this way, the belt conveyors 2 at both ends can output the cut autoclaved aerated concrete blocks separately. During cutting, cold water is supplied to the pipe joint 10 through an external cold water pump, and then sprayed on the cutting head of the cutting machine 6 through the nozzle 9. This can cool the cutting head and prevent dust from splashing during cutting. The water generated during spraying is blocked by the splash guard 11.
