Description

Technical Field

[0001] This invention belongs to the field of concrete block production technology, specifically relating to an automatic rebar insertion device for concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight, porous, heat-insulating, fire-resistant, nailable, sawable, planable, and earthquake-resistant new building material with environmental advantages.

[0003] In the mass production of aerated concrete blocks, the aerated concrete block slurry needs to be poured into a mold frame for casting, steel bars are added, and then the blocks are manufactured through processes such as static curing, cutting, and high-pressure steam curing. Currently, the addition of steel bars is done manually, inserting rows of steel bar mesh. However, due to manual operation, the control is poor, the error is large, the uniformity of the steel bar mesh is not good, resulting in poor quality assurance. Furthermore, the production efficiency is low. Summary of the Invention

[0004] The present invention provides an automatic rebar insertion device for concrete blocks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic rebar insertion device for concrete blocks, comprising a hydraulic cylinder, a crossbeam at the upper end of the hydraulic cylinder, a fixing plate at the lower end of the hydraulic cylinder, fixing strips evenly arranged at the bottom of the fixing plate, and multiple sets of insertion rods fixed at the lower ends of the fixing strips, a first hot-melt plastic sleeve sleeved in the middle of the insertion rod, a second hot-melt plastic sleeve sleeved at the bottom end of the insertion rod, and bending clips provided on the upper side of both the first and second hot-melt plastic sleeves.

[0006] Preferably, the fixing strip is provided with a placement groove on its outside, the placement groove is opened on the bottom surface of the fixing plate, the bottom sides of the fixing strip are abutted by movable plates, the movable plates are slidably connected inside the fixing plate, and a pull block is provided at one end of the movable plate that passes through the fixing plate.

[0007] Preferably, threaded holes are provided on both sides of the fixing strip, and threaded rods are threadedly connected inside the threaded holes. The threaded rods are provided on both sides of the fixing plate and are threadedly connected to the fixing plate. A rotating block is provided at one end of the threaded rod that extends outward.

[0008] Preferably, a limiting block is provided at the lower end of the movable plate, and a limiting groove is provided on the outside of the limiting block, the limiting groove being formed at the bottom of the fixed plate.

[0009] Preferably, the bottom of the second hot-melt plastic sleeve is closed.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This invention involves sequentially fitting a first hot-melt plastic sleeve and a second hot-melt plastic sleeve onto an insert rod, then sequentially inserting the reinforcing bars of the mesh reinforcement into bending clips. A hydraulic cylinder lowers a fixing plate, moving the insert rod and the mesh reinforcement into the hot-melt slurry. This causes the first and second hot-melt plastic sleeves and the bending clips to melt and decompose in the slurry, leaving the mesh reinforcement in the slurry. After settling to allow the slurry to harden, the hydraulic cylinder rises, lifting the insert rod. This completes the automatic insertion of reinforcing bars, resulting in uniform reinforcement arrangement, improved product quality, high production efficiency, and the ability to handle mass production.

[0012] 2. The fixing strip provided in this invention is detachable, which facilitates the fitting of the insertion rod with the first hot-melt plastic sleeve and the second hot-melt plastic sleeve. When disassembling, pull the pull blocks on both sides to move the movable block, and the fixing strip can be taken out from the placement groove. After fitting the insertion rod with the first hot-melt plastic sleeve and the second hot-melt plastic sleeve, the installation is completed. The installation and disassembly are convenient and quick. After disassembly, it is easy to install the first hot-melt plastic sleeve and the second hot-melt plastic sleeve, thereby improving the installation efficiency. Moreover, through the action of the limiting block and the limiting groove, the movable block is limited to the fixing plate, avoiding the disadvantage of it falling and being lost.

[0020] Please see Figure 1-5 The present invention provides the following technical solutions:

[0021] Example 1

[0022] An automatic rebar insertion device for concrete blocks includes a hydraulic cylinder 1. A crossbeam 2 is provided at the upper end of the hydraulic cylinder 1, and a fixing plate 3 is provided at the lower end of the hydraulic cylinder 1. Two sets of hydraulic cylinders 1 are provided to ensure the stability of the lifting and lowering of the fixing plate 3. Fixing strips 7 are evenly arranged at the bottom of the fixing plate 3. Multiple sets of insertion rods 4 are fixed at the lower end of each fixing strip 7. A first hot-melt plastic sleeve 5 is sleeved in the middle of the insertion rod 4, and a second hot-melt plastic sleeve 6 is sleeved at the bottom end of the insertion rod 4. Bending clips 8 are provided on the upper side of both the first hot-melt plastic sleeve 5 and the second hot-melt plastic sleeve 6. The bending clips 8 are made of plastic and can be manually turned to hold the inserted mesh rebar. The first hot-melt plastic sleeve 5, the second hot-melt plastic sleeve 6, and the bending clips 8 are all made of plastic with a low melting point. In this embodiment, polyvinyl acetate plastic is selected. The bottom of the second hot-melt plastic sleeve 6 is closed to facilitate installation and prevent it from changing position when it falls into the grout.

[0023] Specifically, first, the first hot-melt plastic sleeve 5 and the second hot-melt plastic sleeve 6 are sequentially inserted onto the insert rod 4, and then the reinforcing bars of the mesh reinforcement are sequentially inserted into the bending clips 8, such as... Figure 1 , 2 As shown, the mold frame containing the hot melt slurry is then moved directly below the device. The hydraulic rod of the hydraulic cylinder 1 drives the fixed plate 3 to descend, moving the insert rod 4 and the mesh steel bars into the hot melt slurry. After a period of time, the first hot melt plastic sleeve 5, the second hot melt plastic sleeve 6, and the bending strip 8 are melted and decomposed in the hot melt slurry. Then, the slurry is allowed to stand to achieve a certain hardness. Next, the hydraulic cylinder 1 is raised, driving the insert rod 4 to rise, and the first hot melt plastic sleeve 5 and the second hot melt plastic sleeve 6 are reinstalled. This process is repeated to complete mass production.

[0026] Specifically, the fixing strip 7 can be removed, making it easier to fit the first hot-melt plastic sleeve 5 and the second hot-melt plastic sleeve 6 onto the insertion rod 4, thereby improving installation efficiency. When disassembling, pull the pull blocks 10 on both sides to pull out the movable block 14, and the fixing strip 7 can be taken out from the placement groove 9. After fitting the insertion rod 4 with the first hot-melt plastic sleeve 5 and the second hot-melt plastic sleeve 6, during installation, place the fixing strip 7 into the placement groove 9, and then push the pull block 10 so that the movable block 14 abuts against the lower end face of the fixing strip 9, thereby completing the support and fixation. Through the action of the limiting block 15 and the limiting groove 16, the movable block 14 is limited on the fixing plate 3 to avoid the disadvantage of it falling off and being lost.
