Description

Technical Field

[0001] This utility model relates to the field of pipe marking technology, specifically a marking machine for a PE pipe production line. Background Art

[0002] PE pipes are made from polyethylene electrofusion fittings as the main raw material and are formed by extrusion. They are widely used in water supply pipelines and other fields. They not only have excellent corrosion resistance and convenient installation, but also have good flexibility and low temperature resistance. With their excellent physical and chemical properties, PE pipes have become an indispensable material in municipal construction, agricultural irrigation and other fields.

[0003] In existing technologies, in order to improve the production efficiency and product quality of PE pipes, workers use inkjet printers to print production information on PE pipes, thereby obtaining relevant information about the pipes. When the inkjet printer prints on the PE pipes, it is necessary to position the pipes using a limiting mechanism. However, since the pipe sizes and specifications are not the same, workers need to constantly adjust the limiting mechanism when positioning pipes of different sizes, which is cumbersome, inefficient, and has poor applicability. Utility Model Content

[0004] The purpose of this invention is to provide a coding machine for PE pipe production lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE pipe production line inkjet printer, comprising:

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a PE pipe production line inkjet printer, comprising: a base 1, with fixed plates 2 fixedly installed on the middle of both sides of the top of the base 1, a threaded rod 10 rotatably installed on the rear of the fixed plates 2 on the side close to each other, a guide rod 11 fixedly installed on the front of the fixed plates 2 on the side close to each other, a movable seat 7 slidably installed on the guide rod 11, the rear side of the movable seat 7 threadedly connected to the outer periphery of the threaded rod 10, a fixed seat 4 fixedly installed on one side of the top of the base 1, and a drive mechanism 3 provided at the rear of the top of the base 1. The drive mechanism 3 is used to drive the threaded rod 10 to rotate. By controlling the drive mechanism 3, the threaded rod 10 will rotate synchronously. Due to the characteristics of the thread, the movable seat 7 will move axially along the guide rod 11, thereby adjusting the distance between the fixed seat 4 and the movable seat 7, which is beneficial for adapting to the limiting of PE pipes of different lengths and facilitating the inkjet printer body 12 to print on the PE pipes.

[0022] A pipe limiting mechanism 6 is provided, located at the midpoint of the side of the fixed base 4 and the movable base 7, respectively. The pipe limiting mechanism 6 includes an outer ring 604 and an inner ring 606, which are fixedly installed at the midpoint of the side of the fixed base 4 and the movable base 7, respectively. Multiple evenly distributed movable grooves 605 are formed in the midpoint of the inner rings 604 and 606, and movable plates 608 are slidably installed within each movable groove 605. Wedge-shaped limiting blocks 6010 are fixedly installed at the ends of the fixed seat 4 and the movable seat 7 respectively. A gear ring 603 is rotatably installed in the middle of the outer ring 604. A rack 609 is fixedly installed on the surface of the movable seat 7. Multiple evenly distributed gears 607 are rotatably installed on the sides of the fixed seat 4 and the movable seat 7 respectively, and the gears 607 in the same group mesh with the gear ring 603 and the rack 609 respectively. A fixing frame 602 is fixedly installed at the lower part of the sides of the fixed seat 4 and the movable seat 7 respectively. The middle of the fixing frame 602 is fixed A cylinder 601 is installed, with its output end fixedly mounted on the end of a movable plate 608 near the fixed bracket 602. When the PE pipe is placed between the movable seat 7 and the fixed seat 4, the piston rod inside the cylinder 601 pushes one of the movable plates 608 to move within the movable groove 605. Because the rack 609, gear 607, and gear ring 603 mesh with each other, the gear 607 on the same side drives the gear ring 603 to rotate within the outer ring 604. The system enables the other movable plates 608 to move synchronously. Furthermore, the movable plates 608 are circumferentially distributed within the outer ring 604 and the inner ring 606. When all the movable plates 608 move synchronously, the wedge-shaped limiting blocks 6010 will move closer to or further away from each other, thereby limiting the PE pipe from the inside. This system is applicable to the limiting and fixing of PE pipes of different sizes. Moreover, the internal fixing method does not affect the coding operation of the inkjet printer body 12 on the outer circumference of the PE pipe.

[0023] A number of evenly distributed support rods 5 are fixedly installed close to each other on one side of the fixed base 4 and the other side fixed plate 2. A movable frame 9 is slidably installed on the outer periphery of the lower support rod 5. The inkjet printer body 12 is fixedly installed on the top of the movable frame 9. The upper part of the movable seat 7 is slidably installed on the outer periphery of the support rod 5. Springs 13 are sleeved on the other side of the outer periphery of the support rod 5. A hydraulic cylinder 8 is rotatably installed on the other side of the top of the base 1. The output end of the hydraulic cylinder 8 is movably installed in the middle of the bottom end of the movable frame 9. By setting support rods 5 and springs 13 on support rods 5, the stability of the movable seat 7 during movement can be increased, which facilitates the inkjet printer body 12 to print on PE pipes. In addition, the hydraulic cylinder 8 can push the movable frame 9 to move on the support rod 5, which facilitates the inkjet printer body 12 to print on different positions of PE pipes. It has good flexibility. At the same time, there is a large gap between the movable seat 7 and the mounting seat of the hydraulic cylinder 8. The two will not interfere with each other during the movement of the movable seat 7. The movable seat 7 can move normally along the guide rod 11.

[0024] The drive mechanism 3 includes a stepper motor 301, which is fixedly installed on the rear side of the top of the base 1. A drive wheel 302 is fixedly installed on the drive end of the stepper motor 301. The drive wheel 302 drives the driven wheel 303 to rotate through a synchronous belt 304. The driven wheel 303 is fixedly installed on one end of the threaded rod 10. The surface of the wedge-shaped limiting block 6010 is provided with multiple evenly distributed anti-slip grooves. By controlling the stepper motor 301, the stepper motor 301 can drive the drive wheel 302 to rotate. Since the drive wheel 302 is connected to the driven wheel 303 through the synchronous belt 304, the driven wheel 303 can drive the threaded rod 10 to rotate. Due to the characteristics of the thread, the movable seat 7 will move. Furthermore, the operator can control the forward or reverse rotation of the stepper motor 301 to realize the forward or reverse rotation of the threaded rod 10. Thus, the operator can flexibly adjust the position of the movable seat 7, which is suitable for limiting PE pipes of different sizes.

[0025] In actual use, the operator places one end of the PE pipe on the inner ring 606 of the fixed seat 4, and then controls the cylinder 601, which, in conjunction with the movable plate 608, gear 607, rack 609, and gear ring 603, can engage the wedge-shaped limiting block 6010 inside one end of the PE pipe. Then, by controlling the stepper motor 301 in the drive mechanism 3, which, in conjunction with the drive wheel 302, driven wheel 303, and synchronous belt 304, can the threaded rod 10 rotate, thereby adjusting the position of the movable seat 7. After adjustment, the operator controls the cylinder 601 on the movable seat 7 again, at which point the wedge-shaped limiting block 6010 on the movable seat 7 will limit and fix the other end of the PE pipe. After the limiting is completed, the hydraulic cylinder 8 pushes the moving frame 9 to move, and at the same time, the inkjet printer body 12 will print on the PE pipe. After the printing is completed, the operator can remove the PE pipe.
