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.

[0026] See also Figure 1-4 and Figure 6The utility model provides a technical solution: an environmentally friendly and pollution-free steel pipe internal and external plastic coating production device, comprising a machine base 1 and a storage box 4, a No. 1 stand 2 is installed at one end of the machine base 1, a No. 2 stand 11 is installed at the other end of the machine base 1, a support assembly 6 is installed in the middle of the machine base 1, and an external plastic coating assembly 9 is installed on the side of the No. 1 stand 2 close to the support assembly 6, the storage box 4 is arranged above the machine base 1 close to the No. 1 stand 2, one side of the storage box 4 is connected to a pressure pump 5 through a conduit, and the pressure pump 5 is connected to the external plastic coating assembly 9 through a hose An inner plastic-coated component 3 is installed on the base 1 near the top of the support component 6, an electric slide rail 10 is installed inside the No. 2 stand 11, and a moving frame 14 is slidably connected to the side of the electric slide rail 10 near the support component 6, and a cleaning mechanism 13 is installed on one end of the moving frame 14. A No. 3 stand 7 is installed on the side of the base 1 away from the inner plastic-coated component 3, and a cylinder 15 is installed on one end of the No. 3 stand 7. The end of the No. 3 stand 7 is connected to a limiting mechanism 8 near the support component 6, and a protective mechanism 12 is installed on the base 1 near the top of the support component 6.

[0027] according to Figure 1-2 and Figure 4-5 As shown, the limiting mechanism 8 includes a limiting disk 801, a limiting plate 802, a No. 1 bidirectional screw 803, a support spring 804 and a driving assembly 805, one end of the cylinder 15 is connected to the limiting disk 801, a No. 1 bidirectional screw 803 is installed in the built-in groove of the limiting disk 801 through a bearing, one end of the No. 1 bidirectional screw 803 is connected to the driving assembly 805, the outer side of the No. 1 bidirectional screw 803 is sleeved with a support spring 804 and a limiting plate 802, the limiting plate 802 and the No. 1 bidirectional screw 803 are threadedly sleeved, one side of the limiting plate 802 is installed with spaced balls, and the cross-sectional shape of the limiting plate 802 is semicircular.

[0028] During specific implementation, since most steel pipe plastic coating production devices are supported in the middle of the steel pipe and lack a limit on one end of the steel pipe, the steel pipe is prone to shaking and deviating during rotation and spraying. The steel pipe can be placed on the support assembly 6, so that the driving rollers at both ends of the support assembly 6 are attached to the outer side of the steel pipe, and the steel pipe is clamped and limited once, and then one end of the steel pipe is docked with the limit plate 801, so that one end of the steel pipe is placed on the inner side of the limit plate 802, and then the drive assembly 805 is started, so that the drive assembly 805 drives the No. 1 two-way screw rod 803 to rotate, and then the limit plates 802 are close to each other on the No. 1 two-way screw rod 803, and at the same time, the support spring 804 supports the position of the limit plate 802, and the limit plate 802 clamps the steel pipe, so that the placement of the steel pipe is more stable, thereby improving the stability of the environmentally friendly and pollution-free steel pipe internal and external plastic coating production device.

[0029] according to Figure 2 and Figure 6 As shown, the protective mechanism 12 includes a vertical rod 121, a No. 2 bidirectional screw rod 122, a protective plate 123 and a motor 124. A No. 2 bidirectional screw rod 122 is installed in the built-in groove of the machine base 1 close to the support assembly 6 through a bearing, one end of the No. 2 bidirectional screw rod 122 is connected to the motor 124, the outer side of the No. 2 bidirectional screw rod 122 is threadedly sleeved with the vertical rod 121, and a protective plate 123 is installed above the vertical rod 121, and the cross-sectional shape of the protective plate 123 is arc-shaped.

[0030] During specific implementation, since the material is easy to splash onto the operator when the external plastic coating component 9 is spraying on the outside of the steel pipe, the motor 124 can be used to drive the second bidirectional screw 122 to rotate, so that the vertical rod 121 drives the protective plate 123 to approach each other, and the position of the protective plate 123 can be adjusted to protect the outside of the steel pipe, reduce the splash of the spray material, and improve the safety of the environmentally friendly and pollution-free internal and external plastic coating production device of the steel pipe.

[0031] according to Figure 2-3 As shown, the cleaning mechanism 13 includes a connecting rod 131, a reset spring 132, a mounting plate 133 and a cleaning roller 134. The connecting rod 131 runs through one end of the movable frame 14. The reset spring 132 is sleeved on the outer side of the connecting rod 131. The mounting plate 133 is connected to the lower side of the connecting rod 131. The cleaning roller 134 is installed on the inner side of the mounting plate 133 through a movable shaft. The outer side of the cleaning roller 134 is sleeved with a dust sticking sleeve.

[0032] During specific implementation, when the steel pipe is exposed, some dust will adhere to the surface, and the dust will affect the plastic coating effect. The electric slide rail 10 can be used to drive the movable frame 14 to move left and right. When the steel pipe is driven to rotate by the support assembly 6, the cleaning roller 134 adheres to the dust on the outside of the steel pipe. Due to the different sizes of some steel pipes, the cleaning roller 134 will squeeze the connecting rod 131 upward during the cleaning process, so that the connecting rod 131 drives the reset spring 132 to contract, and then the reset spring 132 rebounds and drives the connecting rod 131 to push the mounting plate 133 downward, so that the cleaning roller 134 is close to the outer wall of the steel pipe, and the dust is quickly adhered, which is beneficial to improving the practicality of the environmentally friendly and pollution-free steel pipe internal and external plastic coating production device.

[0033] Working principle: When using this environmentally friendly and pollution-free steel pipe internal and external plastic coating production device, first, place the steel pipe on the support assembly 6, then clamp and limit one end of the steel pipe through the limiting mechanism 8, and then clean the outer wall of the steel pipe through the cleaning mechanism 13. As the support assembly 6 drives the steel pipe to rotate, the inner plastic coating assembly 3 sprays the inner wall of the steel pipe. At the same time, the pressure pump 5 sucks the paint from the storage box 4 and transports it to the outer plastic coating assembly 9, and then the outer side of the steel pipe is sprayed through the outer plastic coating assembly 9. During the spraying process, the protective mechanism 12 is used to reduce paint splashing, which is beneficial to improve the practicality of the environmentally friendly and pollution-free steel pipe internal and external plastic coating production device.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
