Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building material production, in particular to a concrete plate production device with plate reinforcing agent added. BACKGROUND

[0002] As a key structural material in the field of construction, concrete plates are widely used in the fields of fabricated building floors, wall plates and decorative plates. With the increasing requirements of building industrialization on material performance, the addition of plate reinforcing agents such as fiber reinforcing agents and polymer modifiers in the concrete matrix can significantly improve the bending strength, crack resistance and durability of the plate. However, the existing production devices still have significant technical bottlenecks in the aspects of reinforcing agent addition and process control.

[0003] 1. Insufficient control of reinforcing agent dispersion uniformity

[0004] Traditional stirring equipment mostly uses horizontal double-shaft stirrers with fixed rotation speed, which is difficult to adapt to the physical characteristics of different reinforcing agents. For example, steel fibers tend to agglomerate, leading to uneven distribution, and polymer emulsions are prone to local enrichment due to viscosity differences.

[0005] 2. Low coupling degree of reinforcing agent addition timing and process

[0006] The existing production line generally uses a pre-mixed feeding method, ignoring the optimal mixing process window of the reinforcing agent. Experiments show that the addition of cellulose ether reinforcing agent in the later stage of stirring can improve the bonding effect by 30%, but the existing equipment lacks a multi-stage precise feeding mechanism, resulting in a utilization rate of less than 60% of the performance of the reinforcing agent.

[0007] Therefore, how to add plate reinforcing agents in the production equipment while being able to process the added plate reinforcing agents is a problem that needs to be solved by those skilled in the art. SUMMARY

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] A concrete slab production device with added slab reinforcement, such as Figure 1 As shown, it includes a supporting mechanism 1, a moving mechanism 2, a table mold 3 and a distribution mechanism 4. The top of the supporting mechanism 1 is slidably connected to the moving mechanism 2 for longitudinal movement. The bottom of the supporting mechanism 1 is provided with a table mold 3 for carrying concrete for plate production. The top of the moving mechanism 2 is slidably connected to the distribution mechanism 4. The bottom of the distribution mechanism 4 is provided with a discharge mechanism 5 for feeding concrete raw materials into the table mold 3.

[0034] During concrete slab production, external signals control the movement mechanism 2 to move longitudinally at the top of the support mechanism 1, while the material distribution mechanism 4 is controlled to move laterally at the top of the movement mechanism 2. During this movement, the material discharging mechanism 5 is controlled to discharge the concrete raw materials inside the material distribution mechanism 4 to the bottom table 3. Subsequent vibration and other process operations are combined to produce the concrete slab.

[0035] like Figure 2 As shown, the support mechanism 1 includes a support frame 11 , a longitudinal guide rail 12 is provided on the top of the support frame 11 , and a console 13 is fixedly installed on the rear side of the support frame 11 .

[0036] The longitudinal movement of the moving mechanism 2 is guided by the longitudinal guide rail 12 at the top of the supporting frame 11 , and the control console 13 is used to carry numerical control equipment in the prior art to control the concrete slab production equipment.

[0037] The moving mechanism 2 includes a moving frame 21 , which is slidably connected to the top of the longitudinal guide rail 12 , and a transverse guide rail 22 is provided at the top of the crossbeam of the moving frame 21 .

[0038] The movable frame 21 moves on the top of the longitudinal guide rail 12 , driving the transverse guide rail 22 to move, thereby realizing the longitudinal movement of the material distributing mechanism 4 .

[0039] The table formwork 3 includes a template 31, which is arranged below the supporting mechanism 1. The bottom end of the template 31 is fixedly connected to a ferry car 32, and the bottom end of the ferry car 32 is provided with a ferry guide rail 33. The ferry car 32 drives the template 31 to move with the help of the ferry guide rail 33, thereby transporting the completed concrete slabs.

[0040] The template 31 is used to carry the concrete raw materials output by the distribution mechanism 4 through the discharge mechanism 5, so as to form a concrete slab at the top of the template 31. The shuttle rail 33 then guides the shuttle car 32 to move, allowing the shuttle car 32 to drive the template 31 to move, so that the next template 31 can move to the bottom of the distribution mechanism 4 to produce another concrete slab.

[0041] like Figure 3 As shown, the material distribution mechanism 4 includes a hopper 41, a hopper wheel 42 is provided on the outside of the hopper 41, and a plurality of feeding mechanisms 44 are installed on the inside of the hopper 41. The hopper wheel 42 is provided at the top of the transverse guide rail 22 for controlling the movement of the hopper 41 at the top of the transverse guide rail 22. A concrete inlet 43 is provided at the top of the hopper 41.

[0042] The hopper wheel 42 is used to cooperate with the transverse guide rail 22 to control the transverse movement of the entire distribution mechanism 4, introduce the concrete raw materials into the hopper 41 through the concrete inlet 43, and use the feeding mechanism 44 to add and mix the required plate reinforcement to the concrete raw materials.

[0043] like Figure 4 As shown, the hopper 41 includes a hopper shell 411, and a tilted material guide plate 412 is fixedly connected to the inner side of the hopper shell 411. The bottom end of the material guide plate 412 is fixedly connected to a solenoid valve 413. The solenoid valve 413 controls the flow between the top and bottom ends of the material guide plate 412. The solenoid valve 413 is a proportional valve.

[0044] The concrete inlet 43 is used for adding and mixing. The guide plate 412 carries the concrete raw materials introduced from the concrete inlet 43 into the hopper shell 411. The solenoid valve 413 receives an external signal and guides the processed concrete raw materials to the bottom end for subsequent production processing.

[0045] like Figure 5 As shown, each feeding mechanism 44 includes a processing mechanism 441, and a corresponding guide mechanism 442 is slidably provided at the bottom end of each processing mechanism 441. All guide mechanisms 442 are fixedly connected to the inner side of the hopper shell 411, and the processing mechanism 441 passes through the guide mechanism 442 and is fixedly connected to a stirring paddle 443.

[0046] The put-in plate material reinforcing agent is broken by the processing mechanism 441, so that the caked plate material reinforcing agent can be restored to powder, and the stirring paddle 443 is used for mixing and stirring the concrete at the bottom of the guide mechanism 442.

[0047] As shown in Figure 6 The processing mechanism 441 comprises a central shaft 4411, the outer side of the central shaft 4411 is fixedly connected with a material receiving cylinder 4412, the bottom end of the material receiving cylinder 4412 is fixedly connected with two symmetrical double-screw extruders 4413, the screw surface of the double-screw extruder (4413) is provided with staggered breaking teeth, the screw rotation speed is adjustable, and the screw rotation speed is 50-300 rpm,

[0048] The bottom end of each double-screw extruder 4413 is fixedly connected with a corrugated pipe 4414, the corrugated pipe (4414) is made of corrosion-resistant flexible material, the inner wall is coated with an anti-sticking coating, the bottom end of the corrugated pipe 4414 is fixedly connected with a material guide pipe 4415, the bottom end of the central shaft 4411 is fixedly connected with a guide rod 4416 corresponding to the position of the material guide pipe 4415, the top end of the guide rod 4416 penetrates through a sliding groove 4417, and the material guide pipe 4415 is slidably connected to the inner side of the guide rod 4416 through the sliding groove 4417.

[0049] The material receiving cylinder 4412 is used for carrying and storing plate material additives, the plate material additives are output to the corrugated pipe 4414 under the action of the double-screw extruder 4413, and finally introduced into the bottom end of the guide mechanism 442 through the material guide pipe 4415.

[0050] The guide mechanism 442 comprises a guide plate 4421, the guide plate 4421 is fixedly connected to the inner side of the hopper shell 411, two center-symmetrical vortex grooves 4422 are formed in the inner side of the guide plate 4421, and the material guide pipe 4415 is slidably connected to the inner side of the guide plate 4421 through the vortex grooves 4422.

[0051] The material receiving cylinder 4412 and the guide rod 4416 are synchronously rotated by the central shaft 4411, so that the material guide pipe 4415 is guided to move through the sliding groove 4417 and the vortex groove 4422. In the process of rotating the central shaft 4411, the guide rod 4416 rotates synchronously with the material receiving cylinder 4412, so that the material guide pipe 4415 moves transversely relative to the guide rod 4416. The material guide pipe 4415 changes the radius of rotation under the guidance of the vortex groove 4422, and cooperates with the guide rod 4416 to drive the material guide pipe 4415 to move. The plate material reinforcing agent treated by the double-screw extruder 4413 is output to the bottom end through the corrugated pipe 4414 and the material guide pipe 4415, and the guidance of the vortex groove 4422 can make the plate material reinforcing agent be put into the concrete raw materials in a larger range. At the same time, in the process of putting, the material guide pipe 4415 can also realize the function of stirring to a certain extent.

[0052] like Figure 3 As shown, the discharging mechanism 5 includes a fixed baffle 51, an outer side of the fixed baffle 51 is fixedly connected to an axis bracket 52, an outer side of the axis bracket 52 is rotatably connected to a transmission bracket 53, the top of the transmission bracket 53 is fixedly connected to a cylinder 54, the fixed end of the cylinder 54 is rotatably connected to the outer side of the fixed baffle 51, and the bottom end of the transmission bracket 53 is fixedly connected to a baffle plate 55, and the cylinder 54 controls the transmission bracket 53 to drive the opening and closing of the baffle plate 55.

[0053] The cylinder 54 is controlled by an external signal, so that the output end of the cylinder 54 drives the transmission bracket 53 to move. Under the restriction of the shaft bracket 52, the transmission bracket 53 drives the bottom baffle plate 55 to flip over, thereby opening the material distribution mechanism 4, so that the concrete raw materials with the addition of the plate reinforcement can be placed on the bottom template 31 to realize the production of concrete plates.

[0054] During use, the desired plate reinforcement is first added to the receiving drum 4412. Then, the concrete raw material to be added is fed into the distribution mechanism 4 through the concrete inlet 43. After passing through the concrete inlet 43, the concrete raw material falls onto the top of the guide plate 412 and accumulates at the bottom of the guide mechanism 442. An external motor then rotates the central shaft 4411, which in turn drives the twin-screw extruder 4413 via an electrical signal. The plate reinforcement in the receiving drum 4412, after being crushed and dispersed by the twin-screw extruder 4413, passes through the bellows 4414 and enters the guide pipe 4415. The central shaft 4411 drives the material receiving tube 4412 to rotate, thereby driving the guide tube 4415 to slide inside the slide groove 4417 through the guide rod 4416, and the vortex groove 4422 drives the guide tube 4415 to perform a vortex motion with a variable radius. At the same time, the plate reinforcer processed by the twin-screw extruder 4413 falls into the concrete raw material at the bottom of the vortex groove 4422 through the guide tube 4415. The rotation of the central shaft 4411 can disperse the plate reinforcer inside the guide tube 4415 into the concrete raw material. At the same time, the rotation of the stirring paddle 443 can fully mix the concrete raw materials and the plate reinforcer, thereby ensuring the delivery effect of the plate reinforcer. After the mixing is completed, the cylinder 54 is activated by an external electrical signal, and the cylinder 54 drives the transmission bracket 53, so that the baffle plate 55 is opened, so that the concrete raw materials after internal mixing can fall and enter the top of the template 31. When the concrete raw materials fall, the mobile frame 21 is driven to move by an external signal to control the longitudinal movement of the material distribution mechanism 4. The hopper wheel 42 is controlled to move by an external signal to control the lateral movement of the material distribution mechanism 4, thereby controlling the casting and forming of the concrete slab.
