Description

Technical Field

[0001] The utility model relates to the field of coating tooling, in particular to a multi-head coating tooling for plastic-coated composite steel pipes. Background Technique

[0002] A multi-head coating tooling for plastic-coated composite steel pipes is a device used for coating plastic-coated composite steel pipes. The term "multi-head" refers to a device with multiple coating heads, which can accelerate the coating speed and improve the coating efficiency.

[0003] After retrieval, the existing Chinese patent publication number is: CN217450673U, a multi-head coating tooling for socket-type plastic-coated composite steel pipes, including a support frame. The top of the support frame is fixedly connected with a support seat. The bottom of the cross plate is attached to the top of the support seat. A spraying unit is arranged above the cross plate. The spraying unit includes a first roller shaft, a hub motor, a fixed frame, an arc track, a driving wheel, a support rod, an arc tube, a nozzle and a hose. The front of the hub motor is fixedly connected with a fixed frame. The utility model relates to the technical field of socket-type plastic-coated composite steel pipe production. This multi-head coating tooling for socket-type plastic-coated composite steel pipes realizes the clamping and fixing of the steel pipe and its uniform rotation through the cooperation of the first roller shaft, the hub motor and the fixed frame, which is convenient for subsequent coating. At the same time, the automatic coating of the inner wall of the steel pipe is realized by using the driving wheel, the arc tube and the nozzle, which greatly reduces the working burden of the user, improves the working efficiency, and is also convenient for installation and operation by the user.

[0004] In the specific implementation of the above patent, when the user wants to adjust the distance between the two first roller shafts according to steel pipes of different diameters, start the first servo motor to drive the double-headed stud to rotate. The double-headed stud drives the two first sleeves threadedly connected thereto to approach or move away from each other. The two first sleeves drive the two fixed frames fixedly connected thereto to approach or move away from each other, and finally realize the approach or separation of the two first roller shafts. After the adjustment of the first roller shaft is completed, then start the second servo motor. Driven by the second servo motor, the reciprocating screw rod rotates, and then drives the second sleeve connected thereto to move. Due to the limitation of the side wall groove of the support frame, the second sleeve can only move vertically along the side wall groove of the support frame. The second cylinder drives the cross bar fixedly connected thereto to move vertically, and finally realizes the vertical movement of the second roller shaft, so as to adjust it according to steel pipes of different diameters and realize the further clamping and fixing of steel pipes of different diameters. In this patent, the threads on both sides of the double-headed stud are opposite. When the double-headed stud rotates, it can drive the two first sleeves to approach and move away from each other, and finally realize the clamping and fixing of steel pipes of different diameters, improving the applicability of the device. However, in this patent, multiple groups of motors need to be used in cooperation to clamp the steel pipe adaptively, and each group of motors needs to be independently controlled, which increases the complexity of the system and also increases the manufacturing cost and operation cost of the overall equipment. Therefore, a multi-head coating tooling for plastic-coated composite steel pipes is proposed to solve the above problems. Summary of the Invention

[0036] As Figure 1 and Figure 4As shown in the figure, the rotating assembly includes a motor 16 and a rotating rod 17. The nozzle 19 is installed on the left side of the sliding frame 15. The left side of the motor 16 is fixedly connected to the driving end of the motor 16.

[0038] Working principle: When the inner wall of the steel pipe needs to be coated, the steel pipe needs to be clamped and fixed first. When clamping the steel pipe, the steel pipe needs to be placed on the placing rack 2 and the rotating wheel 5 first, and then the electric push rod 12 is started. The electric push rod 12 will push the sliding wedge 13 to slide and raise the lifting block 4 through the lifting wheel 14. Under the action of the lifting block 4, the two adjusting wheels 9 will also drive the clamping wheel 8 to press down on the steel pipe through the rotating frame 7 to fix steel pipes of different diameters and thicknesses. By avoiding the use of multiple motors when clamping and fixing the steel pipe, the complexity of the system is reduced, and the manufacturing cost and operating cost of the overall equipment are reduced. After the fixing is completed, the inner wall of the steel pipe needs to be coated with plastic. By moving the sliding frame 15, the position of the material storage cylinder 18 can be moved and the material storage cylinder 18 can be sent into the inner wall of the steel pipe. The motor 16 will drive the rotating rod 17, thereby rotating the material storage cylinder 18. At this time, the material storage cylinder 18 will cooperate with the nozzle 19 to coat the inner wall of the steel pipe. Before coating, the first telescopic rod 20 and the second telescopic rod 21 will support the pushing spring 22. The pushing spring 22 will push the cleaning plate 23 to closely adhere to the inner wall of the steel pipe, thereby cleaning the inner wall of the steel pipe. By cleaning the inner wall of the steel pipe through the cleaning device, impurities such as oil stains, rust, and dust on the inner wall of the steel pipe can be better removed, ensuring that the coating can better adhere to the inner wall of the steel pipe and improving the adhesion and stability of the coating.
