AI Technical Summary
In the current production of PC steel bars, the air blowers produced by simple blowers are not concentrated enough and the air force is unstable. They cannot accurately control the air direction, resulting in uneven drying of the steel bar surface and local residual moisture, which affects subsequent processing and product quality.
A drying device including rollers and air distribution blocks was designed. The rollers are rotated by the friction between them and the steel rods. The air distribution blocks provide multi-angle airflow to ensure uniform drying of all parts. A drive screw and gear system is used to achieve stable rotation and movement, and high-pressure gas is centrally transported.
This technology enables uniform and efficient drying of the PC steel bar surface, improving product quality and production efficiency, and ensuring the performance and safety of the steel bar in subsequent processing.

DETAILED DESCRIPTION

Based on the embodiments in the present utility model, all the other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the present utility model.
[0026] The utility model provides a kind of blow drying device for PC steel rod production, as shown in figure Figures 1 to 5 It includes base 1, the upper surface of base 1 is equipped with middle stand 101 on both sides, the both sides of base 1 are equipped with back plate 102, the both sides of the side surface of middle stand 101 are equipped with decorative hole 2, the inner arc surface of decorative hole 2 is connected with rotating shaft rod 3, one end of rotating shaft rod 3 is connected into decorative hole 2, and roller 4 is movably connected, the outer arc surface of roller 4 is movably connected with synchronous belt 5, the middle part of the side surface of middle stand 101 is equipped with through hole 6, the inner arc surface of through hole 6 is movably connected with driving screw 7, the outer arc surface of driving screw 7 is screw-connected with bearing bracket 8, the inner arc surface bottom of bearing bracket 8 is equipped with shaft component 801, shaft component 801 is screw-connected with driving screw 7, the back of bearing bracket 8 is fixedly installed with blowing distribution block 9 by bolt, the number of roller 4 is four, and two two are a group and symmetrically distributed, the outer arc surface one end of one roller 4 is fixedly installed with bevel gear A10, the outer arc surface serration of bevel gear A10 is meshingly connected with bevel gear B11, one end of bevel gear B11 is fixedly installed with motor 12, support rod 13 is fixedly installed between two rollers 4, one end of support rod 13 is slidably connected into bearing bracket 8, one end of one rotating shaft rod 3 is fixedly installed with driving gear 14, driving screw 7 is fixedly installed with driven gear 15 on the side close to roller 4, driven gear 15 is meshingly connected with driving gear 14, and blowing distribution block 9 is placed on the upper surface of base 1.
[0027] The output end of the motor 12 on one side drives the bevel gear A10 to rotate at high speed, and in the process of rotation, it forms a precise meshing transmission relationship with the bevel gear B11, thereby driving the bevel gear B11 to rotate synchronously. The rotational movement of the bevel gear B11 further acts on the rollers 4 on the shaft rod 3, causing relative movement between the two. There are four rollers 4 in total, two of which are rigidly connected by a support rod 13 to achieve linkage effect, and the other two are connected by a synchronous belt 5 to ensure that the entire roller 4 system can start rotating in unison. When one of the rollers 4 starts rotating, the driving gear 14 connected to it also rotates, and through gear meshing, it drives the driven gear 15 to rotate, which in turn drives the driving screw 7 connected to it to rotate. The bearing bracket 8 is installed on the driving screw 7 and is driven by the shaft part 801, thereby realizing back-and-forth reciprocating movement under the rotation of the driving screw 7. At the same time, the outer surface of the roller 4 is in close contact with the surface of the PC steel rod. With the continuous rotation of the roller 4, a stable and uniform friction force is generated between the roller 4 and the PC steel rod. Under the driving of this friction force, the PC steel rod attached to the roller 4 rotates around its own axis. In this way, the rotating PC steel rod can make each part of it correspond to the air outlet of the blow-drying device in turn, thereby ensuring uniform and efficient blow-drying operation of each part of the PC steel rod and greatly improving the blow-drying effect and product quality.
[0028] The inner arc surface of the blow-distribution block 9 is provided with an arc-shaped air chamber 16, one side of the outer arc surface of the blow-distribution block 9 is provided with a universal air nozzle 17, the other side of the outer arc surface of the blow-distribution block 9 is connected through an air nozzle air inlet 18, one end of the air nozzle air inlet 18 is connected through an air nozzle pipeline 19, one end of the air nozzle pipeline 19 is connected through the universal air nozzle 17, and the universal air nozzle 17 is connected and adapted to the arc-shaped air chamber 16.
[0029] A bearing support 8 is accurately installed above the driving screw 7, which plays a key supporting and bearing role during the operation of the whole device. Two blow distribution blocks 9 are symmetrically installed behind the bearing support 8. The outer arc surfaces of the two blow distribution blocks 9 are connected with universal air nozzles 17 and air nozzle inlets 18, and air nozzle pipelines 19 are tightly installed on the air nozzle inlets 18, forming a complete and efficient gas conveying and distribution system. When the device starts to work, the total controller will send accurate electrical signals again according to the preset program, and then control the electromagnetic valve to open rapidly. At this time, high-pressure gas will be stably output from the air nozzle pipeline 19 and transmitted along the pipeline system into the arc-shaped air cavity 16. Due to the design of the arc-shaped air cavity 16, the gas will form concentrated and uniform airflow in it, and finally blow out from the universal air nozzles 17 on the blow distribution blocks 9. In this process, the bearing support 8 moves back and forth under the action of the driving screw 7, while the PC steel bar in close contact with the roller 4 continuously rotates under the driving of friction force. The reciprocating movement and rotating movement cooperate and interact with each other, so that the concentrated wind force blown out from the universal air nozzles 17 can cover the surface of the PC steel bar in all directions and at multiple angles, thereby realizing uniform and efficient blow-drying treatment of the surface of the PC steel bar, effectively improving the quality and efficiency of blow-drying, and ensuring the performance and quality of the PC steel bar in the subsequent processing or use process.
