Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a PCCP pipe horizontal automatic spraying device. Background Technology

[0002] With economic development and social progress, industrial production is moving towards mechanization and automation, with equipment integrating more and more functions and gradually developing towards multi-functionality. Pipe production equipment should also follow this trend, reducing manual labor and moving towards automation and intelligence. Pipe lettering is the final process in pipe manufacturing, and the quality of the spraying equipment greatly affects the pipe's appearance. Currently, the traditional method is used for lettering on finished pipes: a metal plate with the lettering is etched, attached to the pipe, and then manually sprayed while holding the plate at both ends.

[0003] The existing spraying process has the following problems: the spraying process is time-consuming and labor-intensive and the spraying effect is poor.

[0004] Based on the above situation, there is an urgent need for a PCCP pipe horizontal automatic spraying device to solve the problems of time-consuming, labor-intensive and poor-quality results. Utility Model Content

[0005] The purpose of this invention is to solve the problems of time-consuming, labor-intensive, and poor-quality spraying in existing processes.

[0006] The technical solution of this utility model is as follows: A horizontal automatic spraying device for PCCP pipes, comprising: Support base, wherein a travel guide rail is slidably connected to the support base; A pipe-flipping mechanism is installed on the support base and used to flip the pipe body; A spraying mechanism is installed on the flipping mechanism, and the spraying mechanism includes a letter plate and a spray head installed on the letter plate.

[0007] The existing spraying process is time-consuming, labor-intensive, and produces poor spraying results. In this solution, a crane is used to lift the tube onto a tube-flipping mechanism, which flips the tube from a vertical position to a horizontal position. At the same time, the spraying mechanism is activated, and the nozzle sprays pigment onto the lettering board and through the hollow part of the lettering board to reach the tube, realizing automatic spraying. The flipping process and the spraying process are carried out simultaneously, which improves production efficiency and solves the problems of being time-consuming, labor-intensive, and producing poor results.

[0008] Furthermore, to facilitate spraying the entire length of the tube, one feasible solution is as follows: a rack is installed on the letter plate, and a gear that meshes with the rack is installed on the spray head, with the gear connected to a spraying motor. In this solution, the spraying motor drives the gear to rotate, thereby moving the spray head along the extension direction of the rack and performing spraying.

[0009] Furthermore, in order to further improve the spraying effect, one feasible solution is: the letter plate is rotatably connected to the tube flipping mechanism and a cylinder is installed between the letter plate and the tube flipping mechanism. When this solution is adopted, the cylinder drives the letter plate to rotate and contact the tube body, reducing the distance between the nozzle and the tube body, and further improving the spraying effect. After the spraying is completed, the cylinder drives the letter plate to reverse and move away from the tube body.

[0010] Furthermore, this solution does not exclusively limit the specific structure of the pipe-flipping mechanism. One feasible solution is that the pipe-flipping mechanism includes an L-shaped plate rotatably connected to the support base, and a hydraulic cylinder is installed between the L-shaped plate and the support base. When this solution is adopted, the hydraulic cylinder drives the L-shaped plate and the pipe body to flip synchronously, thereby causing the pipe body to flip from a vertical position to a horizontal position.

[0011] Furthermore, in order to fix the tube body, one feasible solution is to provide a pad for supporting the tube body on the L-shaped plate. When this solution is adopted, the tube body is supported and fixed by the pad, which can prevent the tube body from moving relative to the L-shaped plate during the flipping process.

[0012] Furthermore, to facilitate the transportation of the tube, one feasible solution is to install a wheel set on the support base that cooperates with the guide rail, and the wheel set is connected to a travel motor. When this solution is adopted, the travel motor drives the wheel set, thereby driving the support base to transport the tube along the guide rail. During the transportation process, the tube is flipped and sprayed simultaneously, which further improves production efficiency.

[0013] Compared with existing technologies, the beneficial effects of this utility model are: 1. A crane is used to lift the tube body onto the tube flipping mechanism, and the tube flipping mechanism flips the tube body from a vertical position to a horizontal position. At the same time, the spraying mechanism is started, and the nozzle sprays pigment onto the letter plate and reaches the tube body through the hollow part of the letter plate, realizing automatic spraying. The flipping process and the spraying process are carried out simultaneously, which improves production efficiency and solves the problems of time-consuming, labor-intensive and poor effect. 2. Since a rack is installed on the letter plate, and a gear that meshes with the rack is installed on the spray head and the gear is connected to a spraying motor, the spraying motor drives the gear to rotate, thereby driving the spray head to move along the extension direction of the rack and perform spraying. Third, since the letter plate is rotatably connected to the tube-flipping mechanism and a cylinder is installed between the letter plate and the tube-flipping mechanism, the letter plate is rotated by the cylinder and comes into contact with the tube body, which reduces the distance between the nozzle and the tube body and further improves the spraying effect. After the spraying is completed, the cylinder drives the letter plate to reverse and move away from the tube body. Attached Figure Description

[0016] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] Example: Please refer to Figure 1 , Figure 3 and Figure 5A horizontal automatic spraying device for PCCP pipes, comprising: Support base 1, the support base 1 is slidably connected to the travel guide rail; The pipe-flipping mechanism 2 is installed on the support base 1 and is used to flip the pipe body 4; The spraying mechanism 3 is mounted on the pipe flipping mechanism 2. The spraying mechanism 3 includes a letter plate 31 and a spray nozzle 32 mounted on the letter plate 31.

[0019] The existing spraying process is time-consuming, labor-intensive, and produces poor spraying results. In this solution, a crane is used to lift the tube body 4 onto the tube flipping mechanism 2, and the tube flipping mechanism 2 flips the tube body 4 from a vertical position to a horizontal position. At the same time, the spraying mechanism 3 is started, and the nozzle 32 sprays pigment onto the letter plate 31 and reaches the tube body 4 through the hollow part of the letter plate 31, realizing automatic spraying. The flipping process and the spraying process are carried out simultaneously, which improves production efficiency and solves the problems of being time-consuming, labor-intensive, and producing poor results.

[0020] To facilitate spraying the entire length of the tube body 4, one feasible solution is as follows: a rack 33 is installed on the letter plate 31, and a gear that meshes with the rack 33 is installed on the nozzle 32, with the gear connected to a spraying motor. Specifically, in this embodiment, a slide rail 35 is installed on the letter plate 31, and the nozzle 32 is slidably connected to the slide rail 35. When this solution is adopted, the spraying motor drives the gear to rotate, thereby driving the nozzle 32 to move along the extension direction of the rack 33 and perform spraying.

[0021] Reference Figure 1 and Figure 4 To further improve the spraying effect, one feasible solution is that the letter plate 31 is rotatably connected to the tube flipping mechanism 2 and a cylinder 34 is installed between the letter plate 31 and the tube flipping mechanism 2. Specifically, in this embodiment, a hinge end 24 is formed on the tube flipping mechanism 2 and the letter plate 31 is installed on the hinge end 24. When this solution is adopted, the cylinder 34 drives the letter plate 31 to rotate and contact the tube body 4, which reduces the distance between the nozzle 32 and the tube body 4 and further improves the spraying effect. After the spraying is completed, the cylinder 34 drives the letter plate 31 to reverse and move away from the tube body 4.

[0022] Reference Figure 2 This solution does not limit the specific structure of the pipe-flipping mechanism 2. One feasible solution is: the pipe-flipping mechanism 2 includes an L-shaped plate 21 that is rotatably connected to the support base 1. A hydraulic cylinder 22 is installed between the L-shaped plate 21 and the support base 1. A shaft 12 that is rotatably connected to the L-shaped plate 21 is formed on the support base 1. When this solution is adopted, the hydraulic cylinder 22 drives the L-shaped plate 21 and the pipe body 4 to flip synchronously, thereby causing the pipe body 4 to flip from a vertical position to a horizontal position.

[0023] Reference Figure 4To fix the tube body 4, one feasible solution is to provide a pad 23 for supporting the tube body 4 on the L-shaped plate 21. Specifically, in this embodiment, the pad 23 is provided with a silicone layer or a rubber layer, and an arc-shaped groove that mates with the tube body 4 is formed on the pad 23. When this solution is adopted, the tube body 4 is supported and fixed by the pad 23, and the tube body 4 is further limited by the arc-shaped groove. The silicone layer or rubber layer increases the friction, which can prevent the tube body 4 from moving relative to the L-shaped plate 21 during the flipping process.

[0024] Reference Figure 1 To facilitate the transport of the tube body 4, one feasible solution is to install a wheel set 11 on the support base 1 that cooperates with the guide rail, and the wheel set 11 is connected to a travel motor (not shown in the figure). When this solution is adopted, the wheel set 11 is driven by the travel motor, which in turn drives the support base 1 to transport the tube body 4 along the guide rail. During the transport process, the tube body 4 is flipped and sprayed at the same time, which further improves the production efficiency.

[0025] The working principle of this embodiment: A crane is used to place the pipe body 4 vertically on the L-shaped plate 21. The hydraulic cylinder 22 drives the L-shaped plate 21 and the pipe body 4 to rotate synchronously, thereby turning the pipe body 4 from vertical to horizontal. At the same time, the cylinder 34 drives the letter plate 31 to rotate and contact the pipe body 4. The spraying motor drives the spray nozzle 32 to move along the extension direction of the rack 33, thereby spraying the pipe body 4. The walking motor drives the wheel set 11, thereby driving the support seat 1 to transport the pipe body 4 along the guide rail. During the transportation process, the pipe body 4 is turned over and sprayed simultaneously.

[0026] To address the issues of time-consuming, labor-intensive, and ineffective production, this solution employs a crane to lift the tube body 4 onto the tube-flipping mechanism 2. The tube-flipping mechanism 2 then flips the tube body 4 from a vertical position to a horizontal position. Simultaneously, the spraying mechanism 3 is activated, and the nozzle 32 sprays pigment onto the letter plate 31, which then reaches the tube body 4 through the hollowed-out portion of the letter plate 31. This achieves automatic spraying, with the flipping and spraying processes occurring simultaneously, thus improving production efficiency and resolving the problems of time-consuming, labor-intensive, and ineffective production.

[0027] To facilitate spraying, in this solution, a rack 33 is installed on the letter plate 31, and a gear that meshes with the rack 33 is installed on the nozzle 32. The gear is connected to a spraying motor. The spraying motor drives the gear to rotate, thereby moving the nozzle 32 along the extension direction of the rack 33 and performing spraying.

[0028] In order to improve the spraying effect, in this solution, since the letter plate 31 is rotatably connected to the tube flipping mechanism 2 and a cylinder 34 is installed between the letter plate 31 and the tube flipping mechanism 2, the cylinder 34 drives the letter plate 31 to rotate and contact the tube body 4, reducing the distance between the nozzle 32 and the tube body 4, and further improving the spraying effect. After the spraying is completed, the cylinder 34 drives the letter plate 31 to reverse and move away from the tube body 4.
