During initial state, the positioning mechanisms 4 located on both sides of the pipe transportation mechanism 1 are not in contact with the petroleum pipe, after the petroleum pipe is transported and blocked by the baffle 2, the pipe transportation mechanism 1 stops running, the drive plate 33 is driven to descend by the extension of the movable end of the first electric cylinder 34, the drive plate 33 drives the two drive rods 35 to do synchronous approaching motion through the drive groove 331, and meanwhile, the two drive rods 35 are limited by the limit groove 322, so that the two drive rods 35 do synchronous approaching motion on the same water level, namely, the positioning mechanisms 4 located on both sides of the pipe transportation mechanism 1 are driven to gradually approach the petroleum pipe until the positioning mechanisms 4 are in contact with the surface of the petroleum pipe, as the two sides of the petroleum pipe are uniformly stressed, the petroleum pipe is arranged in the pipe transportation mechanism 1, meanwhile, the code spraying mechanism 5 is driven to descend in the descending process of the code spraying mechanism 33, the surface of the petroleum pipe is driven to approach the surface of the code spraying mechanism 5, and the adjustment work before code spraying is completed.
After the to-be-positioned mechanism 4 clamps and fixes the pipe, the code spraying mechanism 5 acts to spray codes on the pipe, and the code spraying mechanism 5 also adopts the existing equipment, so that the to-be-positioned mechanism is not repeated as the to-be-sprayed mechanism is not a key point to be considered in the technical scheme required to be protected. Because the code spraying mechanism 5 is close to the pipe in the vertical direction through the driving mechanism 3 before operation, in order to protect the code spraying mechanism 5 (prevent the code spraying mechanism 5 from directly colliding with the pipe), the bottom of the driving plate 33 is connected with the mounting plate 51, the mounting plate 51 is arranged behind the code spraying machine nozzle 52, one end, away from the code spraying machine nozzle 52, of the mounting plate 51 is provided with the fixing seat 53, the rear end face of the fixing seat 53 is provided with the plurality of sliding grooves 511, in the embodiment, the two sliding grooves 511 are respectively connected with the sliding blocks 551 in a sliding mode, the lower ends of the two sliding blocks 551 are jointly provided with the pressing plate 55, the lower end face of the pressing plate 55 is provided with the inward-bent cambered surface for increasing the contact area of the pressing plate 55 and the petroleum pipe, the pressing plate 55 and the fixing seat 53 are jointly provided with the plurality of second springs 54, in the embodiment, the second springs 54 are arranged in a bilateral symmetry mode, and the number of the second springs is two springs 54. It should be noted that the arc-shaped surface at the bottom of the pressing plate 55 is always located below the inkjet printer nozzle 52, and in the descending process of the driving plate 33, the pressing plate 55 can be in contact with the petroleum pipe before the inkjet printer nozzle 52, so that a distance is kept between the inkjet printer nozzle 52 and the petroleum pipe, damage to the inkjet printer nozzle 52 due to collision is avoided, the pressing plate 55 extrudes the upper side of the petroleum pipe, and the pressing plate is matched with the two positioning mechanisms 4 to fix the pipe in three directions. Meanwhile, when the pipes are continuously moved to the code spraying station through the pipe conveying mechanism 1, friction occurs between the pressing plate 55 and the surface of the petroleum pipe, so that impurities such as dust on the surface of the pipe are removed, and the definition of code spraying information is ensured.
The positioning mechanism 4 is used for clamping the petroleum pipe and realizing the relative fixation of the code spraying mechanism 5 and the pipe.
Specifically, as shown in fig. 6, the positioning mechanism 4 includes two sets of rollers 47 that keep the same with the transportation direction of the pipe transportation mechanism 1, the two sets of rollers 47 are respectively arranged at two sides of the pipe transportation mechanism 1, each set of rollers 47 is provided with two, the two rollers 47 at the same side deviate from one end of the pipe transportation mechanism 1, the mounting frame 41 is jointly installed at one end of the pipe transportation mechanism 1, the upper end of the mounting frame 41 is fixedly connected with the lower end of the driving rod 35, and the lower end of the mounting frame 41 is fixedly connected with the upper end of the reinforcing rod 36. When the code spraying mechanism 5 is driven by the first electric cylinder 34 to move downwards to be close to the pipe, the two groups of rollers 47 continuously move towards each other, and finally the four rollers 47 are attached to the outer wall of the pipe to clamp the pipe.
In practical application, the pipes have different types, and the calibers of the pipes of different types are different, so that in order to adapt to the petroleum pipes with different pipe diameters, the vertical distance between the two rollers 47 on the same side can be adjusted, and the specific adjustment is driven by the arranged power module. The concrete structure of power module is as shown in fig. 6, it is including installing the electronic jar 42 of second in mounting bracket 41 inside, mounting bracket 41 is the U-shaped structure, mounting bracket 41 is close to the one end of tubular product transport mechanism 1 and installs guide bar 43, guide bar 43 is the V-arrangement structure, sliding sleeve 44 is all installed at the both ends of guide bar 43, sliding sleeve 44 is the slope setting with mounting bracket 41, two sliding sleeve 44 equal activity cup joints slide bar 45, the output of the electronic jar 42 of second runs through guide bar 43 and swivelling joint has two connecting rods 48, two connecting rods 48 are the dislocation set around taking the electronic jar 42 output of second as the center, two connecting rod 48 other ends rotate through the pivot with two slide bars 45 respectively and are connected, the one end that mounting bracket 41 was kept away from to two slide bars 45 respectively with gyro wheel 47 fixed connection. The present invention is described by taking an example of shortening the distance between two rollers 47 on the same side: the second electric cylinder 42 is started, the movable end of the second electric cylinder extends and drives the two connecting rods 48 to synchronously rotate towards each other, so that the included angle between the two connecting rods 48 close to one side of the mounting frame 41 is reduced, meanwhile, the other ends of the two connecting rods 48 respectively pull the two sliding rods 45 to synchronously move close to each other along the sliding sleeve 44, and further, the two rollers 47 gradually close to each other in the vertical direction.
