Description

Technical Field

[0001] This utility model relates to the field of prefabricated composite floor slab processing, and in particular to a roughening machine for prefabricated composite floor slabs. Background Technology

[0002] A roughening machine for precast composite floor slabs is a mechanical device specifically designed to roughen the surface of precast composite floor slabs. Roughening is a process that creates a rough texture on the concrete surface, aiming to increase the adhesion between the concrete surface and other materials (such as paint, tiles, waterproofing layers, etc.), thereby improving the overall durability and stability of the structure.

[0003] According to the search, for example, the precast composite floor slab roughening machine disclosed in Chinese Patent No. CN 207344810 U includes a frame, a support crossbar fixed to the upper part of the frame and a roughening mechanism suspended below the support crossbar. Because of the roughening mechanism, the roughening process can be automatically completed during the transfer of the precast composite floor slab, which saves manpower and is more efficient than the traditional manual process.

[0004] However, the aforementioned precast composite floor slab texturing machine requires the texturing vertical rods to come into contact with the precast composite floor slabs during use. This causes cement to easily adhere to the texturing vertical rods, which cannot be cleaned after texturing is completed, leading to clumping and affecting future use. Furthermore, when the texturing vertical rods become worn, they need to be replaced entirely, resulting in unnecessary waste.

[0005] Therefore, it is essential to invent a texturing machine for prefabricated composite floor slabs. Utility Model Content

[0029] Example

[0030] Reference Figure 1-5 A surface roughening machine for precast composite floor slabs includes a workbench 1 and a gantry frame 3. The workbench 1 has cleaning zones 10 at both ends of its upper surface to clean cement adhering to the roughening component 7 when it moves to the cleaning zone 10. Electric linear guides 2 are fixedly installed on both sides of the workbench 1 to drive the gantry frame 3, which in turn drives the drive component and the roughening component 7 to reciprocate along the workbench 1. Both ends of the gantry frame 3 are fixedly connected to the output ends of the two electric linear guides 2. A drive component is fixedly installed on the gantry frame 3, which can adjust the height between the roughening component 7 and the workbench 1 to roughen precast composite floor slabs of various thicknesses. Several roughening components 7 are evenly and rotatably mounted on the drive component to contact the precast composite floor slab for roughening treatment.

[0031] In this embodiment, the cleaning area 10 is provided with a number of cleaning grooves 13 corresponding to the roughening structure, so as to provide a separate cleaning space for the roughening component 7 through the cleaning grooves 13. An integrated plate 12 is formed between every two adjacent cleaning grooves 13, so as to support the nozzle 14 through the integrated plate 12 and ensure the stability of the nozzle 14. A number of nozzles 14 are evenly and fixedly installed on both sides of each integrated plate 12. When the roughening structure moves into the cleaning groove 13, the cement adhering to the roughening structure is cleaned through the nozzles 14.

[0032] In this embodiment, the texturing component 7 includes a base component and a replaceable component. The top of the replaceable component is detachably fixed to the bottom of the base component. Through the arrangement between the base component and the replaceable component, when texturing the precast composite floor slab, only the replaceable component contacts the precast composite floor slab. Thus, when the replaceable component is worn, it can be replaced separately. The base component is rotatably connected to the drive component.

[0033] In this embodiment, a water storage chamber 11 is provided inside each of the two ends of the workbench 1. The water storage chamber 11 is located below the corresponding cleaning area 10. The water storage chamber 11 is connected to the corresponding cleaning tank 13 so that when the lint-removing component 7 enters the corresponding cleaning tank 13 for cleaning, the water storage chamber 11 can collect the generated cleaning wastewater.

[0034] In this embodiment, a water inlet pipe 15 and a water outlet pipe 16 are fixedly installed at each end of the workbench 1. The water inlet pipe 15 is connected to the nozzle 14 of the corresponding cleaning area 10. Through the setting of the water inlet pipe 15, it can be connected to an external water supply device to provide the required cleaning liquid to the nozzle 14. The water outlet pipe 16 is connected to the inside of the corresponding water storage chamber 11 so that the wastewater collected inside the water storage chamber 11 can be discharged through the water outlet pipe 16.

[0035] In this embodiment, the drive assembly includes an electric push rod 4, a U-shaped frame 5, and a support shaft 6. The electric push rod 4 is fixedly installed on the crossbeam of the gantry frame 3. The output end of the electric push rod 4 slides out from the bottom surface of the crossbeam of the gantry frame 3 so as to adjust the distance between the texturing assembly 7 and the workbench 1 according to the thickness of the precast composite floor slab. The output end of the electric push rod 4 is fixedly installed with the U-shaped frame 5 so as to ensure the stability of the support shaft 6. The support shaft 6 is fixedly installed inside the opening of the U-shaped frame 5 so as to ensure the stability and smoothness of each texturing assembly 7 during operation. The texturing assemblies 7 are evenly and rotatably mounted on the support shaft 6. Through the connection structure between the texturing assembly 7 and the support shaft 6, the texturing assembly 7 can adjust its angle according to the contact position with the precast composite floor slab. The U-shaped frame 5 is slidably connected to the two columns of the gantry frame 3.

[0036] In this embodiment, each of the two columns of the gantry frame 3 has a limiting groove 8 on its inner side, so as to limit the U-shaped frame 5 through the limiting groove 8 and ensure the stability of the U-shaped frame 5 during the up and down movement. The two ends of the U-shaped frame 5 are slidably connected to the corresponding limiting groove 8.

[0037] In this embodiment, sliders 9 are fixedly installed at both ends of the U-shaped frame 5. The sliders 9 are slidably placed in the corresponding limiting grooves 8 so as to ensure the stability and smoothness of the U-shaped frame 5 during the up and down movement through the setting of sliders 9 and limiting grooves 8.

[0038] In this embodiment, the base component includes a ring 71, a connecting rod 72, and a connecting port 73. The circumference of the ring 71 is fixedly connected to one end of the connecting rod 72 so that the base component can be connected to the support shaft 6 through the ring 71, while ensuring that the base component can rotate smoothly. The other end of the connecting rod 72 has a connecting port 73 through it, so that the connecting rod 72 can be disassembled and assembled with the replaceable component through the connecting port 73, while also increasing the length of the roughening cutter head 75. The ring 71 is rotatably sleeved on the support shaft 6, and the base component is engaged with the replaceable component through the connecting port 73.

[0039] In this embodiment, the replaceable components include a T-shaped opening 74 and a brushing head 75. The top of the brushing head 75 has a through T-shaped opening 74. The brushing head 75 is engaged with the connecting port 73 on the connecting rod 72 through the T-shaped opening 74. The T-shaped opening 74 and the connecting port 73 enable quick assembly and disassembly between the brushing head 75 and the connecting rod 72.

[0040] When this utility model is used, firstly, according to the thickness of the precast composite floor slab, the distance between the roughening component 7 and the worktable 1 is adjusted by the electric push rod 4 so that the distance between the roughening component 7 and the worktable 1 is greater than the thickness of the precast composite floor slab, and the gantry frame 3 is driven by the electric linear guide rail 2 to move the roughening component 7 to one end of the worktable 1.

[0041] At this point, the precast composite floor slab is placed on the workbench 1 and positioned between the two cleaning zones 10. Then, the roughening assembly 7 is lowered by the electric push rod 4 so that the roughening cutter head 75 contacts the precast composite floor slab.

[0042] After contact, the electric linear guide rail 2 drives the gantry 3 to move the roughening component 7 to the other end of the workbench 1 until the roughening component 7 moves above the corresponding cleaning area 10, thus completing the roughening treatment of the precast composite floor slab.

[0043] After the texturing component 7 moves above the corresponding cleaning area 10, the texturing component 7 is lowered by the electric push rod 4 so that the texturing blade 75 enters the corresponding cleaning tank 13. Cleaning liquid is sprayed onto the texturing blade 75 through the nozzle 14 to remove the cement adhering to the texturing blade 75.

[0044] When the brushing head 75 needs to be replaced later, simply separate the T-shaped opening 74 from the connecting opening 73.

[0045] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
