Description

Technical Field

[0001] This utility model relates to the field of pipe surface treatment and conveying technology, and in particular to an automatic conveying pipe sandblasting machine. Background Technology

[0002] Currently, surface treatment of metal pipe fittings plays a crucial role in industrial production, particularly in industries such as petroleum, chemical, and construction, where extremely high requirements are placed on the corrosion resistance and surface quality of pipe fittings. With continuous industrial development, the application of metal pipe fittings in various engineering projects is becoming increasingly widespread. The quality of their surface treatment directly affects the service life and performance of the pipe fittings, thus impacting the overall quality and safety of the project. Good surface treatment can significantly improve the corrosion resistance of pipe fittings, reduce maintenance costs, and extend their service life. Therefore, the development of surface treatment technology for metal pipe fittings is of great significance to the stable operation and sustainable development of related industries.

[0003] In the surface treatment of metal pipe fittings, various methods are commonly used in the industry to improve the corrosion resistance and surface quality of the fittings. Among them, sandblasting is a common and effective method. Traditional sandblasting mainly relies on manual operation, with workers holding spray guns to sandblast the surface of the pipe fittings. While this method can ensure the sandblasting effect to a certain extent, it is inefficient and the labor intensity of workers is high. Later, some semi-automatic sandblasting equipment gradually emerged. These devices achieved partial automation through simple mechanical devices, such as fixing the pipe fittings in a specific position and then sandblasting them with a spray gun. However, manual loading and unloading operations are still required, and fully automated continuous operation cannot be achieved. In recent years, automated sandblasting equipment has gradually become more widespread. These devices have improved production efficiency and sandblasting quality to a certain extent, but most of them still have shortcomings in pipe fitting transportation.

[0004] However, most existing automated sandblasting equipment suffers from discontinuous conveying. This discontinuity prevents pipe fittings from being processed efficiently and smoothly during sandblasting, reducing overall production efficiency and making it difficult to meet the large-scale, high-efficiency demands for pipe surface treatment in industries such as petroleum, chemical, and construction. Utility Model Content

[0005] This application provides an automatic conveying type pipe sandblasting machine, which realizes continuous conveying of pipes and ensures the automation of pipe sandblasting.

[0006] This application provides an automatic conveying type pipe fitting sandblasting machine, which adopts the following technical solution:

[0007] An automatic conveying pipe sandblasting machine includes a housing, within which a space for sandblasting and a sandblasting assembly are provided. A feed inlet is located on one side of the housing, and a chute is provided at the feed inlet to convey pipes into the housing. A first cylinder pusher plate is located at one end of the chute within the housing. The first cylinder pusher plate is pushed upwards by a cylinder, thereby transporting the pipes below the sandblasting assembly. A belt is located below the sandblasting assembly to discharge the sandblasted pipes.

[0008] By adopting the above technical solution, this utility model designs an automatic conveying pipe sandblasting machine. In use, the chute can be used to convey the pipe into the machine housing. The first cylinder push plate can be pushed upward by the cylinder to transport the pipe to the bottom of the sandblasting component for easy sandblasting. The belt can discharge the sandblasted pipe, realizing automatic conveying of the pipe, improving the efficiency of pipe surface treatment, avoiding the problems of low efficiency and high labor intensity of traditional manual sandblasting, and solving the problem of discontinuous conveying of automated sandblasting equipment, thus meeting the needs of large-volume pipe processing.

[0009] Preferably, the housing is provided with a groove, the outer end of the slide groove rests in the groove, and the other end is hinged to the frame inside the housing. The slide groove is inclined at a certain angle.

[0010] By adopting the above technical solution, a groove is set on the machine casing during use. The outer end of the slide is placed in the groove, and the other end is hinged to the internal frame of the machine casing at a certain angle. Gravity can be used to make the pipe roll into the machine casing along the slide, which improves the feeding efficiency, reduces manual operation, and the slide can be installed and adjusted manually, which enhances the adaptability of the equipment.

[0011] Preferably, the end of the chute is arc-shaped, so that the pipe stays inside the housing after sliding through the chute.

[0012] By adopting the above technical solution, the arc-shaped structure at the end of the chute can prevent the pipe from rolling randomly or sliding out of the designated position after it slides into the machine housing, thus ensuring that the pipe is stably in the state ready for sandblasting.

[0013] Preferably, the sandblasting assembly includes multiple spray guns installed inside the housing, which sandblast the pipe fittings.

[0014] By adopting the above technical solution, multiple spray guns are installed inside the machine casing to sandblast the pipes during use, which can make the sandblasting of the pipes more uniform and meet the processing needs of large batches and high precision pipes.

[0015] Preferably, a roller is provided below the sandblasting assembly, and the pipe is pushed onto the roller by a cylinder push plate. A driven shaft is provided at one end of the belt near the roller. The pipe is rotated by the movement of the belt and the roller. The outer end of the belt is mounted on a drive shaft. A servo motor is provided on one side of the drive shaft and the servo motor is mounted on the housing.

[0016] By adopting the above technical solution, the movement of the belt and the rollers make the pipe rotate during use, which allows all parts of the pipe to be sandblasted more evenly, improving the sandblasting effect and the quality of the pipe surface treatment, and meeting the requirements of high-precision pipe processing.

[0017] Preferably, a second cylinder pusher plate is provided on one side of the belt. The second cylinder pusher plate is used to push the sandblasted pipe onto the belt. The second cylinder pusher plate and the first cylinder pusher plate move in the same way.

[0018] By adopting the above technical solution, during use, the second cylinder pusher plate can be used to smoothly push the sandblasted pipe onto the belt, realizing the automated transfer of the pipe in the discharge stage of the sandblasting machine, and improving the efficiency and continuity of pipe conveying.

[0019] Preferably, a limiting strip is also provided above the belt, which is used to limit the movement of the pipe fitting.

[0020] By adopting the above technical solution, a limiting strip is set above the belt to limit the pipe fittings during use, which can prevent the pipe fittings from shifting or falling during the discharge transportation process, ensure the stability and continuity of the pipe fitting discharge process, and improve the working efficiency of the equipment and the processing quality of the pipe fittings.

[0021] Preferably, the machine casing is provided with a discharge port at the discharge position, and both the inlet and the discharge port are provided with curtains, which are detachably connected by bolts.

[0022] By adopting the above technical solution, curtains can be installed at the inlet and outlet to prevent sand from splashing out during sandblasting, thus avoiding dust pollution. In addition, the curtains can be detached and connected by bolts, which facilitates the replacement and maintenance of the curtains.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. The present invention relates to an automatic conveying pipe sandblasting machine, which uses a chute to convey pipes into the machine housing, and a first cylinder pushes the plate to transport the pipes to the bottom of the sandblasting assembly.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] This utility model discloses an automatic conveying type pipe sandblasting machine, such as Figure 1 and Figure 2 As shown, the assembly includes a housing 1, a chute 4, a first cylinder pusher plate 5, a sandblasting assembly 2, a belt 6, a roller 8, a driven shaft 9, a second cylinder pusher plate 12, and a limiting strip 13. The housing 1 contains a space for sandblasting and the sandblasting assembly 2. A chute 4 is located at the feed inlet 3 on one side of the housing 1 to transport the pipes into the housing 1. The first cylinder pusher plate 5 at one end of the chute 4 pushes the pipes upwards via a cylinder to transport them below the sandblasting assembly 2. The belt 6 below the sandblasting assembly 2 discharges the sandblasted pipes, achieving the beneficial effects of automatic pipe transport and efficient sandblasting. This is because the automatic transport of pipes via the chute 4 reduces manual operation and improves transport efficiency, while the first cylinder pusher plate 5 accurately delivers the pipes to the sandblasting position, and the belt 6 promptly discharges the processed pipes, ensuring the continuity of the entire processing flow.

[0032] Specifically, the housing 1 is the main frame of the entire sandblasting machine, serving to protect the internal components and provide operating space. The housing 1 can be made of high-strength metal materials, such as carbon steel or stainless steel, to ensure its sturdiness and durability. The housing 1 has a groove 7 for housing the outer end of the slide 4, the other end of which is hinged to the frame inside the housing 1, and the slide 4 is inclined at a certain angle. This design allows the pipe fittings to roll on the slide 4 using their own weight, achieving automatic conveying. If the pipe fitting cannot slide due to excessive friction, it can be manually pushed into the machine cavity.

[0033] Furthermore, a switch door is provided on one side of the casing 1. The switch door can be opened manually. At the same time, a viewing window is provided on the switch door for observing the condition inside the casing 1.

[0034] The first cylinder pusher plate 5 is located on one end of the slide groove 4 within the housing 1. It mainly consists of a cylinder and a pusher plate. The cylinder can be a common pneumatic cylinder, and the pusher plate can be a metal plate. The first cylinder pusher plate 5 is pushed upwards by the cylinder, thereby transporting the pipe to below the sandblasting assembly 2. Its working principle is that the piston rod of the cylinder extends, driving the pusher plate upwards, lifting the pipe and pushing it to the designated position. In some cases, electric push rods or other devices can be used to replace the cylinder to achieve the same function.

[0035] The sandblasting assembly 2 includes multiple spray guns 21 installed inside the housing 1. The spray guns 21 can be high-pressure spray guns 21, which use high-pressure airflow to propel abrasive material onto the pipe surface for sandblasting. Simultaneous operation of multiple spray guns 21 improves the efficiency and uniformity of sandblasting. The installation position and angle of the spray guns 21 can be adjusted according to actual needs to ensure complete coverage of the pipe surface. Besides high-pressure spray guns 21, other types of spray guns 21, such as rotary spray guns 21, can also be considered to meet different sandblasting requirements.

[0036] The belt 6 works in conjunction with the roller 8 and the driven shaft 9. The belt 6 is driven by a drive shaft 10 and a driven shaft 9, acting as the driving pulley in the entire device, while the roller 8 is the driven pulley. The belt 6 is made of wear-resistant rubber to ensure its service life. A servo motor 11 is mounted on one side of the drive shaft 10, and drives the drive shaft 10 to rotate, thereby moving the belt 6. The pipe is pushed onto the roller 8 by a cylinder pusher plate. The movement of the belt 6 and the roller 8 cause the pipe to rotate, ensuring that all parts of the pipe surface receive sandblasting evenly. Chain drive or gear drive can also be used instead of belt drive 6.

[0037] The second cylinder pusher plate 12 is located on one side of the belt 6. Its structure and working principle are similar to those of the first cylinder pusher plate 5, and it also consists of a cylinder and a pusher plate. The second cylinder pusher plate 12 is used to push the sandblasted pipe onto the belt 6. It pushes the pipe from the sandblasting position onto the belt 6 through the extension and retraction of the cylinder, realizing further conveying of the pipe. Similarly, electric push rods or other devices can be used to replace the cylinder.

[0038] A limiting strip 13 is positioned above the belt 6 to limit the movement of the pipe fittings. The limiting strip 13 can be a strip-shaped metal plate, fixed to the housing 1 by bolts or other means. The function of the limiting strip 13 is to prevent the pipe fittings from deviating from the track during the conveying process of the belt 6, ensuring that the pipe fittings can be discharged smoothly.

[0039] The casing 1 has an outlet 14 at the discharge position, and curtains 15 are installed at both the inlet 3 and the outlet 14. The curtains 15 are detachably connected by bolts. The curtains 15 can be made of wear-resistant cloth or rubber material, and their function is to prevent sand from splashing out during sandblasting, while also providing some dust protection. When maintenance or cleaning of the inside of the casing 1 is required, the curtains 15 can be easily removed.

[0040] The implementation principle of this embodiment is as follows: This automatic conveying pipe sandblasting machine achieves automatic conveying of pipes through the chute 4, reducing manual operation and improving conveying efficiency. The first cylinder push plate 5 and the second cylinder push plate 12 accurately deliver the pipes to the sandblasting position and the discharge position, ensuring the continuity of the entire processing flow. Multiple spray guns 21 work simultaneously, and the belt 6 and roller 8 drive the pipes to rotate, achieving uniform sandblasting treatment on the surface of the pipes. The curtains 15 at the inlet 3 and the outlet 14 prevent sand splashing and dust leakage, ensuring both the safety of the working environment and improving the processing quality. Compared with the prior art, this sandblasting machine solves the problems of discontinuous conveying, uneven sandblasting, and poor adaptability, and can meet the processing needs of large batches and high-precision pipes.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
