Description

Technical Field

[0001] This utility model relates to the field of block processing, specifically to a high-efficiency aerated concrete billet cutting unit. Background Technology

[0002] Concrete blocks (or simply blocks) are the preferred material in large-scale civil engineering projects. After the blocks are formed, they need to be cut into suitable sizes and shapes using a cutting machine. A cutting machine generally includes a transverse cutting device and a longitudinal cutting device. After the blocks are delivered, they are first cut transversely by the transverse cutting device, and then longitudinally by the longitudinal cutting device. The transverse cutting device generally includes a side peeling device and a transverse cutting mechanism. When the transverse cutting machine is working, the side peeling device first removes the rough surface of the left and right sides of the block, and then the transverse cutting mechanism cuts the block transversely (using multiple vertically arranged steel wires). Currently, existing side peeling devices generally only have one step, that is, directly cutting off the side surface of the block with a cutting blade. However, because the block material is relatively hard, directly cutting with a cutting blade can easily damage the blade, and the block surface is not smooth enough. To this end, the applicant applied for an invention patent entitled "A Fully Automatic Block Cutting Machine" (publication number CN111975960B). However, the side peeling mechanism and the transverse cutting mechanism of the block cutting machine are installed on a bracket to form a transverse cutting device, which results in a very long transverse cutting device in terms of front and rear span, making it inconvenient to transport. In order to shorten the length, the structure of the side peeling mechanism can only be simplified, which in turn leads to the peeling effect of the side peeling mechanism not meeting the requirements, and the peeling residue is easy to accumulate in one place, increasing the cleaning frequency. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a high-efficiency aerated concrete billet cutting unit that has better side peeling effect and is easy to transport.

[0004] This high-efficiency aerated concrete billet cutting unit includes a traveling trolley, a side peeling device, a transverse cutting device, and a longitudinal cutting device. The traveling trolley can sequentially enter the side peeling device, the transverse cutting device, and the longitudinal cutting device on a guide rail. The side peeling device is characterized by: a peeling frame and a side slicing mechanism, a side cutting mechanism, a side slicing mechanism, and a side scraping mechanism mounted on the peeling frame; the side slicing mechanism has two side slicing components, each including a slicing knife holder and multiple vertically mounted slicing knives; the side cutting mechanism includes two side cutting components, each including a wire frame and vertically stretched vertical wires; the side cutting mechanism includes two side cutting components, each including a cutting knife holder and a cutting knife, with the cutting blade facing the feeding direction; the side scraping mechanism includes two side scraping components, each including a scraping knife holder and a scraping knife, with the scraping knife's blade angled towards the feeding direction.

[0005] The transverse cutting device includes a transverse cutting frame, a left connecting column, a right connecting column, a left clamp, a right clamp, a hydraulic cylinder, and a transverse steel wire. The hydraulic cylinder is connected to the left clamp, the left clamp is connected to the left connecting column, and a steel wire connecting seat is connected to the right connecting column. One end of the transverse steel wire is connected to the steel wire connecting seat, and the other end of the transverse steel wire is connected to the piston rod of the hydraulic cylinder.

[0006] A steel wire limiting piece is connected to the left connecting column. The steel wire limiting piece has a V-shaped inlet and a limiting gap communicating with the inlet.

[0007] The left connecting column is connected to a spring steel wire mechanism, which includes a rubber block and a spring steel wire power source that drives the rubber block to move up and down. The rubber block can act on the transverse steel wire.

[0008] Both sides of the front end of the cross-cutting frame are provided with a pallet scraping mechanism. The pallet scraping mechanism includes a scraper head, a scraper support and a spring. The scraper head is connected to a rotating shaft. The rotating shaft is rotatably mounted on the scraper support. The spring is connected to the rotating shaft and enables the scraper head to rotate downward.

[0009] Wire brushes are installed on both sides of the rear end of the cross-cutting frame.

[0010] The longitudinal cutting device includes a longitudinal cutting frame, a lifting frame, and a longitudinal steel wire. The longitudinal steel wire is connected to the lifting frame, which is movably mounted on the longitudinal cutting frame. An end-face peeling mechanism is installed below the rear end of the longitudinal cutting frame. The end-face peeling mechanism includes a peeling scraper and an end-face peeling power source that drives the peeling scraper to move left and right.

Detailed Implementation

[0013] like Figure 1 and Figure 2 As shown, this high-efficiency aerated concrete block cutting unit includes a traveling trolley 1, a side peeling device 2, a transverse cutting device 3, and a longitudinal cutting device 4. The block blocks are placed on the traveling trolley 1 via pallets. The traveling trolley 1 sequentially enters the side peeling device 2, the transverse cutting device 3, and the longitudinal cutting device 4 along the guide rails. The side peeling device 2 removes the sides of the block blocks (for example, if the required width of the finished block is 60cm, the width of the block block is generally around 63cm, requiring the removal of 1.5cm from both sides). The transverse cutting device 3 performs transverse cutting on the block blocks, while the longitudinal cutting device 4 performs longitudinal cutting. Through these three processes, large blocks are cut into smaller blocks that meet the required specifications.

[0014] like Figure 3 As shown, the side peeling device 2 includes a peeling frame 20 and a side-slicing mechanism 21, a side-cutting mechanism 22, a side-slicing mechanism 23, and a side-scraping mechanism 24 mounted on the peeling frame 20. Figure 4As shown, the side-slicing mechanism 21 has two side-slicing mechanism components, left and right. Each side-slicing mechanism component includes a slicing knife holder 211 and multiple vertically mounted slicing knives 210. When the block blank enters between the two side-slicing mechanism components, the slicing knives 210 make slits on the side of the block blank to facilitate the subsequent removal of the side surface. Figure 4 As shown, the side-cutting mechanism 22 includes two cutting components, left and right. Each cutting component includes a wire frame 221 and vertically oriented steel wires 220 (one end of the vertical steel wire 220 is fixed, and the other end is tightened by a hydraulic cylinder 222, which is existing technology). When the block blank continues to move forward, the vertical steel wires 220 can easily cut off the side surface of the block blank because the side surface of the block blank is cut by the cutting knife 210. Figure 5 As shown, the side-cutting mechanism 23 includes two side-cutting assemblies, left and right. Each side-cutting assembly includes a cutting blade holder 231 and a cutting blade 230, with the cutting edge of the cutting blade 230 facing the feeding direction. As the block blank continues to move forward, the cutting blade 230 performs fine processing on the side of the block blank, making the side of the block blank smoother. Figure 5 As shown, the side scraping mechanism 24 includes two side scraping assemblies, one on the left and one on the right. Each side scraping assembly includes a scraper holder 241 and a scraper 240. The blade of the scraper 240 is angled towards the feeding direction. As the block blank continues to move forward, this allows for further finishing of the side surface of the block blank. Since the blade of the scraper 240 is angled towards the feeding direction, it can also scrape away protruding parts or debris stuck to the side surface of the block blank, making the side surface of the block blank smoother.

[0015] Since the side peeling device 2 is an independent structure, it can be transported independently. In addition, this side peeling device 2 includes a side slicing mechanism 21, a side cutting mechanism 22, a side slicing mechanism 23, and a side scraping mechanism 24, which can significantly improve the side surface treatment effect of the block blank. At the same time, the side peeling device 2 can be lengthened, making it less likely to pile up slag.

[0016] After the side skin of the block blank is removed, it enters the transverse cutting device 3 for transverse cutting.

[0017] like Figure 6 As shown, the transverse cutting device 3 includes a transverse cutting frame 30, a left connecting column 32, a right connecting column 31, a left clamp 320, a right clamp, a hydraulic cylinder, and transverse steel wires, as shown. Figure 7As shown, the hydraulic cylinder is connected to the left clamp 320 (the cylinder itself is not shown), the left clamp 320 is connected to the left connecting column 32, and a wire connecting seat (not shown, representing existing technology) is connected to the right connecting column. One end of the transverse wire is connected to the wire connecting seat, and the other end is connected to the piston rod of the hydraulic cylinder. When the block blank enters the transverse cutting device 3, the transverse wire performs transverse cutting on the block blank. The connection between the left clamp 320 and the right clamp allows for easy adjustment of the vertical position of the transverse wire.

[0018] To limit the vertical position of the transverse steel wire and prevent it from bouncing up and down during cutting and affecting the horizontal cutting surface, such as... Figure 7 As shown, a wire limiting plate 322 is connected to the left connecting column 32. The wire limiting plate 322 has a V-shaped inlet and a limiting gap communicating with the inlet. When the transverse wire is placed in the V-shaped inlet of the wire limiting plate 322, the wire limiting plate 322 enters the limiting gap under the guidance of the inlet. In this way, the transverse wire will not jump up and down when cutting, ensuring the horizontal plane of the transverse cutting of the block blank.

[0019] After the horizontal steel wire cuts through the block blank, it leaves behind soil residue, which will affect subsequent cutting. To solve this problem, such as... Figure 7 As shown, a spring wire mechanism is connected to the left connecting column 32. The spring wire mechanism includes a rubber block 370 and a spring wire power source 37 that drives the rubber block 370 to move up and down. Driven by the spring wire power source 37, the rubber block 370 can act on the transverse steel wire, so that the transverse steel wire is bounced up and shaken, and the residual soil on the transverse steel wire can be shaken off.

[0020] After the side skin of the block blank W is removed and it is cut transversely, as follows: Figure 1 As shown, there will be soil residue on the side surface of pallet 5. In order to remove the soil residue on pallet 5, as follows: Figure 9 As shown, a scraping mechanism is provided on both sides of the front end of the cross-cutting frame 30. The scraping mechanism includes a scraper head 34, a scraper support 35, and a spring 36. The scraper head 34 is connected to a rotating shaft 340, which is rotatably mounted on the scraper support 35. The spring 36 is connected to the rotating shaft 340, and the scraper head 34 rotates downward under the action of the spring 36. When the pallet 5 carries the block blank W forward, the scraper head 34 acts on the upper surface of the pallet 5. As the pallet 5 moves forward, the scraper head 34 scrapes away the slag on the pallet 5, keeping the pallet 5 clean.

[0021] After the block blanks are de-skinned and transversely cut, there will be debris adhering to the side surfaces of the pallet. To remove the residual debris from the pallet, such as... Figure 8As shown, wire brushes 33 are installed on both sides of the rear end of the cross-cutting frame 30. When the pallet carries the block blank forward, the wire brushes 33 can brush off the slag on the side surface of the pallet.

[0022] After the block blank is cut horizontally, it enters the longitudinal cutting device 4 for longitudinal cutting.

[0023] like Figure 10 As shown, the longitudinal cutting device 4 includes a longitudinal cutting frame 40, a lifting frame 41, and longitudinal steel wires. The longitudinal steel wires are connected to the lifting frame 41 (the longitudinal steel wires are not shown). The lifting frame 41 is mounted on the longitudinal cutting frame 40 in a lifting manner. By lifting the lifting frame 4, the longitudinal steel wires can longitudinally cut the block blank. The longitudinal cutting device 4 is existing technology (refer to announcement number CN111975960B), and will not be described in detail here. Unlike existing technology, an end-face peeling mechanism is installed below the rear end of the longitudinal cutting frame 40. The end-face peeling mechanism includes a peeling scraper 42 and an end-face peeling power source that drives the peeling scraper 42 to move left and right. The end-face peeling power source drives the peeling scraper 42 to move horizontally left and right. In this way, the peeling scraper 42 cuts a slit on the end face of the block blank. When the longitudinal steel wire close to the end face of the block blank cuts off the end face of the block blank, the end face of the block blank falls off because there is no support at the bottom.
