Description

Technical Field

[0001] The utility model relates to the technical field of coding and marking equipment, in particular to a laser coding machine for pipeline production identification. Background Art

[0002] Laser inkjet printer is a device that uses laser technology to complete coding and marking, and is widely used in the production and processing industry. Compared with inkjet printers, the marks produced by laser inkjet printers are more stable and not easy to fade, and are more suitable for product coding and marking. During pipeline production, in order to set specifications, models, manufacturers, production dates, trademarks and other marks on the pipeline surface, coding and marking will also be performed. Pipeline production is synchronized with pipeline transportation and movement. Therefore, the laser inkjet printer is equipped with a synchronous wheel and a speed sensor. The speed sensor receives the moving speed of the pipeline by rolling the synchronous wheel on the surface of the pipeline, so that the laser inkjet printer can adapt the coding and marking speed according to the moving speed of the pipeline.

[0003] At present, the most common installation method for the synchronous wheel corresponding to the speed sensor is to fix the movable frame connected to the synchronous wheel through a connecting rod, and the connecting rod is rotatably installed on the body of the laser inkjet printer, and the connecting rod is supported by bolts to lock the angle to prevent rotation. However, as the use time increases, the bolt lock is easy to loosen, causing the movable frame to loosen, which in turn causes the contact pressure between the synchronous wheel and the pipeline to decrease, and the linear speed of the synchronous wheel is unstable or cannot keep up with the pipeline transportation speed, resulting in unstable spacing of the marking on the pipeline surface, reduced consistency, and affecting product quality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a laser inkjet printer for pipeline production identification, which is used to solve the problem that when a common laser inkjet printer uses bolts to support a movable frame that connects a rotating rod to lock a synchronous wheel, the locking may become loose, resulting in poor contact between the synchronous wheel and the pipeline, ultimately leading to poor consistency in inkjet marking and affecting product quality.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The laser inkjet printer for pipeline production marking comprises a main box, a lifting frame fixedly mounted on the main box, and an inkjet printer head slidably connected to the lifting frame, wherein a connecting frame is fixedly mounted on one side of the inkjet printer head corresponding to the downstream of the pipeline transportation, the connecting frame is movably hinged with a movable frame, a synchronous wheel in contact with the upper surface of the pipeline is mounted at the lower end of the movable frame, and a tension spring is arranged between the lower part of the movable frame and the connecting frame;

[0007] An adjusting stud is rotatably connected to the upper surface of the main box at a position corresponding to the synchronous wheel, a pulley seat is threadedly sleeved on the adjusting stud, and a supporting pulley supported under the pipeline is installed on the pulley seat.

[0008] Preferably, the connecting frame is movably connected to the front and back sides of the movable frame, and the front and back sides of the connecting frame are provided with limiting grooves, and the front and back sides of the movable frame are fixedly connected with limiting columns slidably connected to the limiting grooves.

[0009] Preferably, the limiting groove is an arc groove, and the corresponding arc center is located on the movable axis of the movable frame.

[0010] Preferably, the adjusting stud is movably mounted on the upper surface of the main box via a shaft seat.

[0011] Preferably, an adjusting ring is fixedly sleeved on the surface of the adjusting stud close to the lower end.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) The utility model uses a movable frame to hinge the synchronous wheel and the speed sensor through a connecting frame, and installs a tension spring under the movable frame to pull downward to increase the contact pressure between the synchronous wheel and the pipeline, thereby ensuring that the synchronous wheel is in stable contact with the moving pipeline. In addition, a support pulley for supporting the pipeline is provided under the synchronous wheel to avoid the problem that the pipeline is not supported at the position corresponding to the laser inkjet printer, causing the pipeline to bend downward and affect the contact effect with the synchronous wheel. The use of the tension spring and the support pulley solves the problem that the common laser inkjet printer uses bolts to press against the movable frame connected to the rotating rod to lock the synchronous wheel, which is prone to loose locking, resulting in poor contact between the synchronous wheel and the pipeline, and ultimately leading to poor consistency in inkjet marking and affecting product quality.

[0014] (2) The pulley seat and the adjusting stud of the utility model are installed by threads. When different types of pipes are sprayed and marked, it is convenient to select the corresponding type of support pulley to support the pipe according to the pipe diameter. The height position of the support pulley can be changed to adapt to the diameter and height position of the pipe by twisting the adjusting ring and the adjusting stud, ensuring that different types of pipes can be in stable contact with the synchronous wheel during spraying and marking.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a laser inkjet printer for pipeline production marking, comprising a main box 1, a lifting frame 2 fixedly installed on the main box 1 and a printer head 3 slidably connected to the lifting frame 2, the printer head 3 is fixedly installed with a connecting frame 5 on one side corresponding to the downstream of the pipeline 4, the connecting frame 5 is movably hinged with a movable frame 6, the connecting frame 5 is movably clamped on the front and back sides of the movable frame 6, and the front and back sides of the connecting frame 5 are both provided with limiting grooves 501.

[0022] The front and back sides of the movable frame 6 are fixedly connected with limit columns 601 that are slidably connected to the limit grooves 501. The limit grooves 501 are arc-shaped grooves, and the corresponding arc center is located on the movable shaft 602 of the movable frame 6. The lower end of the movable frame 6 is equipped with a synchronous wheel 7 that contacts the upper surface of the pipeline 4, and a tension spring 8 is arranged between the bottom of the movable frame 6 and the connecting frame 5.

[0023] An adjusting stud 9 is rotatably connected to the position of the synchronous wheel 7 on the upper surface of the main case 1. The adjusting stud 9 is movably installed on the upper surface of the main case 1 through a shaft seat 12. An adjusting ring 13 is fixedly sleeved on the surface of the adjusting stud 9 near the lower end. A pulley seat 10 is threadedly sleeved on the adjusting stud 9. The height position of the pulley seat 10 can be adjusted according to the height position of the pipe 4. The supporting pulley 11 and the pulley seat 10 of the corresponding size can also be replaced according to the diameter of the pipe 4. The pulley seat 10 is threadedly installed on the adjusting stud 9. A supporting pulley 11 supported under the pipe 4 is installed on the pulley seat 10 to prevent the pipe 4 from bending downward and reducing the contact effect with the synchronous wheel 7.

[0024] Working principle:

[0025] Select a supporting pulley 11 of corresponding model according to the diameter of the pipe 4, and threadably install it on the adjusting stud 9 through the pulley seat 10. According to the height position of the pipe 4, turn the adjusting ring 13 and the adjusting stud 9 to drive the supporting pulley 11 to rise or fall to change the height, so that the supporting pipe 4 remains horizontal, and the movable frame 6 can swing up and down around the movable axis 602. The movable frame 6 is pulled downward by the tension spring 8 to increase the contact pressure between the synchronous wheel 7 and the pipe 4, ensuring that the synchronous wheel 7 and the pipe 4 are in stable contact, thereby ensuring that the moving speed of the pipe 4 is consistent with the rotational linear speed of the synchronous wheel 7, so that the coding marking speed is adapted to the moving speed of the pipe 4, ensuring that the coding marking effect is consistent during the transportation and movement of the pipe 4.
