Because the driving transmission shaft 3a and the first driven transmission shaft 4a are linked through a synchronous gear assembly, the driving transmission shaft 3a, the second driven transmission shaft 5a and the self-adaptive transmission shaft 6a are linked through a chain wheel assembly, so that the two groups of first rust pressing wheels 2a can be synchronously driven to rotate (the two groups of first rust pressing wheels 2a have power), the steel pipe is clamped and impacted up and down, the rust removing effect is improved, and the self-adaptive pressing function is realized, namely, the gap between the two groups of first rust pressing wheels 2a can be adjusted according to the diameter of the steel pipe, the enough pressing force is ensured for rust pressing work, the steel pipe is prevented from being damaged by overlarge pressure, and the structure is very ingenious. Further, the self-adaptive pressing operation is that when the diameter of the steel pipe is larger than the gap between the two groups of first rust pressing wheels 2a, the steel pipe upwards supports the first rust pressing wheels 2a positioned above the steel pipe; in the supporting process, the chain of the chain wheel assembly drives the self-adaptive transmission shaft 6a to move towards the corresponding direction, the self-adaptive compression spring 8a is compressed, and the self-adaptive transmission shaft 6a is tightened; when the diameter of the steel pipe is reduced or the rust removal work is finished, the first rust pressing wheel 2a located above moves downwards under the action of self gravity, the self-adaptive compression spring 8a releases elastic potential energy at the moment, and the self-adaptive transmission shaft 6a is driven to move outwards, so that the chain of the chain wheel assembly is tightened.
When the steel pipe is conveyed downwards to the two groups of second rust pressing wheels 9a, the two groups of second rust pressing wheels 9a clamp and hit the steel pipe left and right, rust on two sides of the steel bar is removed, and therefore preliminary rust removal work is completed.
And continuously conveying the steel pipe downwards to a chemical rust removing mechanism, spraying a rust removing liquid on the outer surface of the steel pipe in the chemical rust removing mechanism, corroding the iron rust on the outer surface of the steel pipe in advance by the rust removing liquid, and removing part of stubborn iron rust. Then, the steel pipe is conveyed into an inner cavity of the rotary drum 3b, the derusting rotary driving mechanism drives (rotates forward and backward according to actual needs) the rotary drum 3b to rotate, and the rotary drum 3b drives the coarse brush module and the fine brush module to rotate. In the rotating process, the plurality of rough brushing steel wires 7b scrape the outer surface of the steel pipe, the surface of the steel pipe is roughly scraped, and the outer surface of the steel pipe is finely brushed by the fine brushing surface of the fine brushing sand block 12b, so that the rust is completely and thoroughly removed. Further, two homogenization rollers 8b are respectively arranged on two sides of the rough brush steel wire 7b, and the homogenization rollers 8b are connected to the rough brush mounting block 6b through an elastic telescopic structure, so that the homogenization rollers 8b are higher than the rough brush steel wire 7b in a natural state. After the steel pipe got into the inner chamber of rotary drum 3b, thick brush steel wire 7b and homogenization cylinder 8b all pasted tightly at the surface of steel pipe, in the rotatory in-process that derusts the steel pipe of thick brush steel wire 7b, homogenization cylinder 8b rolls at the surface of steel pipe, along direction of rotation, homogenization cylinder 8b that is located thick brush steel wire 7b rear not only can carry on spacingly to thick brush steel wire 7b, prevent that thick brush steel wire 7b from receiving the extrusion and too big angle of backward slope, guarantee that thick brush steel wire 7b has sufficient intensity to accomplish the rust cleaning work, can also homogenize the rust cleaning liquid simultaneously, thereby obtain more high-efficient and thorough rust cleaning effect. Wherein, after chemical rust removal, the outer surface of the steel pipe is provided with rust removing liquid, because the distributed clearance of the rough brush steel wires 7b is larger, the rough brush steel wires 7b brush the outer surface of the steel pipe like a rake, thereby digging a plurality of pits on the rust layer on the surface, when the pit is excavated, the rust removing liquid which is originally uniformly distributed on the outer surface of the steel pipe is stirred by the rough brushing steel wire 7b, so that the inner rust on the position is exposed, then a homogenizing roller 8b positioned behind the rough brush steel wire 7b rolls the position of the pit, uniformly and flatly paving the stirred derusting liquid on the outer surface (rust layer) of the steel pipe again to ensure that the derusting liquid enters the pit and is contacted with the rust inside, so as to corrode, and then the fine brushing sand surface with higher density is used for finely brushing the corroded iron rust layer, so as to deeply and comprehensively remove rust.
And the steel pipe after rust removal is continuously conveyed downwards to a steel pipe blanking device C, is switched by a switching transmission structure of the switching mechanism, and is then thrown and blanked by a swinging throwing mechanism of the switching mechanism. Specifically, the steel pipe to be painted is thrown on the inclined blanking section 1-1c of the blanking frame 1c by the swinging throwing mechanism, and the steel pipe automatically moves downwards under the action of self gravity and is transferred to the horizontal discharging section 1-2 c. Because the belt transmission mechanism is arranged above the horizontal discharging sections 1-2c, and the conveying surface of the belt 4c of the belt transmission assembly is parallel to the horizontal discharging sections 1-2c, when the steel pipe enters the limiting conveying gap between the belt 4c of the belt transmission assembly and the horizontal discharging sections 1-2c, the belt 4c of the belt transmission assembly can be extruded on the steel pipe and rolls the steel pipe forwards at a fixed speed, so that the steel pipe moves forwards in sequence. The belt transmission assembly comprises a belt transmission assembly, a belt 4c, a horizontal discharging section 1-2c, a steel pipe conveying section, a belt conveying section and a belt conveying assembly, wherein under the extrusion limit of the belt 4c of the belt transmission assembly, the kinetic energy of the steel pipe transferred from the inclined discharging section 1-1c to the horizontal discharging section 1-2c and the extrusion force of the steel pipe on the inclined discharging section 1-1c to the steel pipe on the horizontal discharging section 1-2c can be offset, so that the steel pipe can be automatically close to the horizontal discharging section 1-2c, and the steel pipes can be orderly managed to be conveyed forwards in the horizontal discharging.
The steel pipe moves forwards along the horizontal discharge section 1-2c under the drive of a belt 4c of the belt transmission assembly. Because the separating and discharging spiral rod 2c is rotationally connected below the horizontal discharging sections 1-2c, when the steel pipe moves to the position above the separating and discharging spiral rod 2c, the steel pipe is clamped into the end part of the spiral groove of the separating and discharging spiral rod 2c, the steel pipe applies forward acting force in the spiral groove along with the continuous driving of the belt 4c of the belt transmission assembly, so as to drive the separating and discharging spiral rod 2c to rotate, the steel pipe moves forward along the spiral groove in the rotating process, because the conveying surface of the belt 4c of the belt transmission assembly is superposed with the first circle of spiral groove of the separating and discharging spiral rod 2c, the steel pipe can move forward along the first circle of spiral groove under the driving of the belt 4c, in the process, the next steel pipe is limited in front of the head end of the separating and discharging spiral rod 2c until the end part of the first circle of spiral groove returns to the horizontal discharging sections 1-2c, the next steel pipe enters the spiral groove again, so that the purpose of separating two adjacent steel pipes is achieved, the interference between the steel pipes and a subsequent painting butt-clamping mechanism is avoided, and the structure is very ingenious. Further, in the process of rotating the separating and discharging screw rod 2c, when the front steel pipe is separated from the driving of the belt 4c, the separating and discharging screw rod 2c pushes the front steel pipe to move forward, and the rotational driving force of the separating and discharging screw rod 2c comes from the rear steel pipe between the belt 4c and the spiral groove, that is, the rear steel pipe drives the front steel pipe to move forward in the steel pipe feeding station.
Then, the transverse moving trolley drives the paint brushing butt-clamping mechanism to move to a steel pipe feeding station, so that the two paint brushing butt-columns 5d are respectively aligned to two end portions of a steel pipe to be painted, then the butt-clamping driving motor 6d drives the hinged disc to rotate in the corresponding direction, the two push-pull rods 7d respectively drive the two paint brushing butt-columns 5d to synchronously approach each other, so that the paint brushing bearing portions 5-1d extend into inner cavities of the end portions of the steel pipe, and the two paint brushing bearing portions 5-1d bear the steel pipe. Further, in order to fix the steel pipe to be painted, the two push-pull rods 7d apply larger acting force to the two painting opposite ejecting columns 5d, so that the two painting pressing portions 5-2d are respectively pressed against the two end faces of the steel pipe. Then the steel pipe is driven by the transverse moving trolley to move above the roller brush 2 d; under the drive of the roller drive mechanism, the roller brush 2d rotationally brushes the paint in the paint box 3d on the steel pipe; meanwhile, the painting rotary driving motor 15d drives the painting to rotate the ejection column 5d, so as to drive the steel pipe to rotate, and paint can be painted on the 360-degree circumferential surface of the steel pipe.
After painting is finished, the transverse moving trolley drives the steel pipe to move towards the direction of a drying inlet of the drying box 1e, and at the moment, a pair of opposite clamping modules of the drying and carrying mechanism for preparing to transfer the steel pipe stay at the position of the drying inlet; because the movable inclined ejecting block 6e is arranged on the painting butt-clamping mechanism, the movable inclined ejecting block 6e is gradually close to the drying butt-abutting column 10e of the butt-clamping module which stays waiting along with the driving of the transverse moving trolley, when the driving inclined ejecting block 6-1e of the movable inclined ejecting block 6e is contacted with the extrusion driving part 10-2e of the drying butt-abutting column 10e, the extrusion driving part 10-2e relatively moves upwards along the driving inclined ejecting block 6-1e along with the continuous driving of the transverse moving trolley, so that the drying butt-abutting column 10e is driven to move outwards, and meanwhile, the butt-abutting spring 12e is compressed, so that the painting conveying mechanism is avoided to convey the steel pipe which is just painted to between the two drying butt-abutting chucks 10-1e, as shown in fig. 40-41. When the extrusion driving part 10-2e crosses the active inclined top surface 6-1e, the opposite-top spring 12e releases potential energy to drive the drying opposite-top column 10e to reset, so that the drying bearing part of the drying opposite-top chuck 10-1e extends into the inner cavity of the end part of the steel pipe, the drying top pressure part is pressed on two end surfaces of the steel pipe, and at the moment, the paint brushing bearing part 5-1d of the paint brushing bearing part of the paint opposite-top chuck and the drying bearing part of the drying opposite-top chuck 10-1e are simultaneously positioned in the inner cavity of the steel pipe, as shown in fig. 42-43.
Then, the butt clamp driving motor 6d in the painting carrying mechanism drives the hinged disc to rotate towards the corresponding direction, the two push-pull rods 7d respectively drive the two painting butt columns 5d to be synchronously away from each other, so that the painting bearing parts 5-1d come out from the inner cavity of the end part of the steel pipe, the steel pipe is transferred into the drying carrying mechanism, the drying carrying mechanism drives the steel pipe to move forwards, and when the steel pipe passes through the drying moving channel, the drying plates 2e which are oppositely arranged up and down generate high temperature, and the drying of paint on the steel pipe is accelerated. When the steel pipe is close to the drying outlet, the extrusion driving part 10-2e is actively close to the driven inclined top surface 7-1e of the fixed inclined top block 7e, along with the continuous driving of the transmission chain 9e, the extrusion driving part 10-2e moves upwards along the driven inclined top surface 7-1e, so that the drying opposite-top column 10e is driven to move outwards, as shown in fig. 44-46, the opposite-top spring 12e is compressed at the same time, no extra driving force is needed, the drying opposite-top chuck 10-1e is evacuated from the inner cavity of the steel pipe, the steel pipe is loosened, then the steel pipe is automatically transferred to a collecting station from the drying outlet, and the dried steel pipe is collected uniformly. Further, after the extrusion driving part 10-2e crosses the driven inclined top surface 7-1e, the opposite-top spring 12e releases potential energy to drive the drying opposite-top column 10e to reset, and the transmission chain 9e continues to drive the opposite-clamp module to circularly move to prepare for carrying the next steel pipe to be dried.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
