[0015] A transfer printing process of a transfer printing device for pipe surface processing comprises the following steps:

[0016] S1. When in use, firstly, the transfer printing device for pipe surface processing is installed as a whole at the work site, then the installation of the electrical equipment in the transfer printing device for pipe surface processing is completed, and the debugging of the coordinated work of each electrical equipment is formed, and the necessary program is compiled to realize the control of the entire work flow of the transfer printing device for pipe surface processing;

[0017] S2. When the surface of the tube is transferred, firstly, the corresponding paint juice is added into the liquid replenishing box and the liquid replenishing barrel, then the dry hot air supply pipeline is connected to the drying component, and the laser generator is installed for the laser engraving component. First, the sliding frame is pulled relative to the sleeve frame, and then the limiting connecting frame is adjusted relative to the sliding frame, so that the inner rod is first pulled out of the sliding circular hole on the sliding frame and then rotated away, and then the inner rod is kept in an inclined state, and the inner rod in the inclined state is inserted into the tube that needs to be transferred, and the relative position of the tube relative to the inner rod is maintained. By first adjusting the limiting connecting frame to move and reset relative to the sliding frame, and then adjusting the sliding frame to reset relative to the sleeve frame, the tube is sleeved on the inner rod, first enters an upright state, and then forms relative contact with the juice absorption layer on the transfer conveyor belt;

[0018] S3. Since the two first servo motors move to realize the movement of the transfer conveyor belt and the movement of the displacement conveyor belt respectively, the paint juice in the liquid replenishing tank flows to the liquid outlet surface under the action of its own gravity, and the paint juice leached from the liquid outlet surface is adsorbed by the juice absorption layer on the transfer conveyor belt, and when the juice absorption layer that absorbs the paint juice moves to form contact with the tube sleeved on the inner rod, the transfer operation on the surface of the tube can be carried out, and under the action of the relative friction between the tube and the juice absorption layer, the moving transfer conveyor belt can cause the tube to form a follow-up rotation, thereby realizing the complete transfer operation on the outer cylinder surface of the tube;

[0019] S4. When the outer surface of the tube is completely covered with paint, the sliding frame is pulled again relative to the sleeve frame to adjust the tube away from the juice absorption layer until the sliding circular hole and the circular hole on the load-bearing bracket are relatively overlapped, and the supporting function of the tube sleeved on the inner plug rod fails. The tube falls under the action of its own gravity. Due to the coordinated movement of the two first servo motors, the tube falls exactly onto the corresponding inner plug limit rod on the displacement conveyor belt after falling. Then the tube will form a synchronous movement with the movement of the displacement conveyor belt, and pass through the drying component and the laser engraving component in sequence to respectively realize the drying of the paint on the tube and the laser engraving of the dried paint. After the laser engraving operation is completed, the tube will enter the area matching the paint dipping ring;

[0020] S5. When the tube enters the area matching the paint ring, the electric telescopic rod works to lower the position of the lifting frame relative to the load-bearing bracket, that is, the paint ring is controlled to be sleeved on the corresponding tube, so as to realize the painting operation of the tube after the laser engraving is completed. After the painting operation is completed, the tube can be pulled out relative to the inserted limit rod.

[0022] 1. In the present invention, through the design of the transfer assembly, the matching tube forms the necessary transfer operation, thereby achieving the basic operation treatment on the surface of the tube.

[0023] 2. In the present invention, the drying component is matched to facilitate the rapid drying of the paint on the surface of the tube after transfer, so as to facilitate the smooth operation of the subsequent laser engraving component.

[0024] 3. In the present invention, the laser engraving assembly is used to form an engraving operation on the paint film transferred onto the tube, so that grooves of corresponding patterns are formed on the paint film.

[0025] 4. In the present invention, through the design of the overprinting component, the grooves carved by the laser on the paint film of the matching tube are filled with paint, thereby achieving the purpose of improving the ornamental value of the tube surface.

[0026] 5. In the present invention, through the design of two auxiliary rotating components, the respective operations of the matching laser engraving component and the drying component are formed to form the necessary rotation adjustment of the corresponding tube, so as to achieve the formation of the surrounding full coverage processing of the tube.

[0043] In summary, the working process of the transfer device for pipe surface processing is as follows: when in use, the transfer device for pipe surface processing is first installed as a whole at the work site, and then the installation of the electrical equipment in the transfer device for pipe surface processing is completed, and the debugging of the coordinated work of each electrical equipment is formed, and the necessary program compilation is formed to realize the control of the entire work process of the transfer device for pipe surface processing. When the pipe is subjected to surface transfer processing, first the corresponding paint juice is added to the replenishing tank 10 and the replenishing barrel 18, and then the dry hot air supply pipeline is connected to the outside for the drying component, and a laser generator is installed for the laser engraving component. First, the sliding frame 12 is pulled relative to the sleeve frame 7, and then the limiting connecting frame 14 is adjusted relative to the sliding frame 12, so that the inner rod 15 is first pulled out and then rotated away from the sliding circular hole on the sliding frame 12, and then the inclined state of the inner rod 15 is maintained, and the inner rod 15 relative to the inclined state is inserted into the pipe that needs transfer operation. The tube is sleeved on the inner rod 15, and maintains the relative position of the tube relative to the inner rod 15, by first adjusting the limit connecting frame 14 to move and reset relative to the sliding frame 12, and then adjusting the sliding frame 12 to reset relative to the sleeve frame 7, so that the tube is sleeved on the inner rod 15, first enters the upright state, and then forms relative contact with the juice absorption layer 9 on the transfer conveyor belt 2. Since the two first servo motors 4 move to respectively realize the movement of the transfer conveyor belt 2 and the movement of the displacement conveyor belt 3, and the paint juice in the liquid replenishment tank 10 flows to the liquid outlet surface 8 under the action of its own gravity, the paint juice leached from the liquid outlet surface 8 will be adsorbed under the action of the juice absorption layer 9 on the transfer conveyor belt 2, and when the juice absorption layer 9 that absorbs the paint juice moves to form contact with the tube sleeved on the inner rod 15, the transfer operation on the surface of the tube can be carried out, and under the action of the relative friction between the tube and the juice absorption layer 9, the moving transfer conveyor belt 2 can prompt the tube to form a follow-up rotation, and then realize the complete transfer operation on the outer cylinder surface of the tube.

[0044] Furthermore, when the outer surface of the tube is completely covered with paint, the sliding frame 12 is pulled again relative to the sleeve frame 7 to adjust the tube away from the juice absorption layer 9, until the sliding circular hole and the circular hole on the load-bearing bracket 1 are relatively overlapped, and the supporting effect of the tube sleeved on the inner insertion rod 15 fails, and the tube falls under the action of its own gravity. Due to the coordinated movement of the two first servo motors 4, the tube falls and just falls on the corresponding inner insertion limit rod 5 on the displacement conveyor belt 3. Then the tube will form a synchronous movement with the movement of the displacement conveyor belt 3, and pass through the drying component and the laser engraving component in sequence to respectively realize the drying of the paint on the tube and the laser engraving of the dried paint. After the laser engraving operation is completed, the tube will Entering the area matching with the paint dipping ring 20, when the pipe enters the area matching with the paint dipping ring 20, the electric telescopic rod 17 works to realize the lowering of the lifting frame 16 relative to the load-bearing bracket 1, that is, the paint dipping ring 20 is controlled to be sleeved on the corresponding pipe, so as to realize the painting operation of the pipe after the laser engraving is completed.

The combined transmission forms the corresponding rotation drive of the transmission shaft 31, and then realizes the rotation drive of the lifting pressure plate 35 slidably connected to the transmission shaft 31, and then realizes the rotation drive of the tube contacting the bottom end of the lifting pressure plate 35, so as to form the rotation drying of the paint film on the tube after transfer. During the downward movement of the first bridge frame 33, the cooperation of the wedge-shaped driving block 45 and the wedge-shaped driven block 46 forms the driving of the drying hood 39 away from the hanging frame 40, so that the drying hood 39 can better form a covering surround with respect to the tube to be dried, so as to improve the drying effect. During the operation of the laser engraving component, the lifting ball screw slide 48 works to realize the control and adjustment of the height direction of the laser head 50, so as to facilitate the formation of different heights with the tube The laser engraving operation on the degree is carried out, and the translation ball screw slide 49 works to realize the horizontal movement adjustment of the laser head 50, so as to facilitate the focus adjustment of the laser head 50 in the horizontal direction relative to the tube, and facilitate the adaptation adjustment of the specific positions of different tubes and different tube diameters. The laser head 50 guides and focuses the laser emitted by the laser generator to realize the engraving operation of the matching tube. When the tube is engraved, the corresponding auxiliary rotation component assists the positioning of the matching tube in the upright state and drives and controls the rotation of the tube. The interior of the paint dipping ring 20 adopts a soft and porous material such as sponge, which is convenient for the adsorption of paint on the one hand, and convenient for the relative insertion and rubbing operation of the matching tube on the other hand.
