Description

Technical Field

[0001] This utility model relates to the field of plastic-coated steel pipe processing technology, and more specifically, to a plastic coating baking device for the inner wall of a plastic-coated steel pipe. Background Technology

[0002] When processing steel pipes, it is usually necessary to coat the inner wall with plastic. After the coating is completed, it needs to be dried. Existing baking equipment makes it difficult to accurately control the temperature when drying the inner wall of the steel pipe with hot air. If the temperature is not properly controlled, the coating quality may be unstable.

[0003] To address the aforementioned issues, patent document publication number CN222402161U discloses a plastic coating baking device for the inner wall of a plastic-coated steel pipe, comprising a conveyor seat and a fixed plate. Rollers are rotatably mounted on the front and rear sides inside the conveyor seat, and a conveyor belt is rotatably mounted on the outer wall of the rollers. Flexible plates are fixedly mounted on both sides of the outer wall of the conveyor belt, and multiple sets of sliding holes are provided inside the fixed plate.

[0004] However, it still has some drawbacks in actual use. For example, the heating rod heats the inner wall of the steel pipe, and the temperature can be precisely controlled, which increases the quality of the heating of the steel pipe. The protective cover and the closing plate protect the regulating motor, which can increase the safety of the regulating motor during operation. However, since the closing plate and the protective cover are fixedly connected, when the regulating motor fails, it cannot be disassembled for maintenance in time, which affects the position adjustment of the heating rod and thus affects the heating effect of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic coating baking device for the inner wall of a plastic-coated steel pipe, so as to solve the problem that the closing plate is difficult to disassemble when the regulating motor fails, which affects the baking effect of the device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic coating baking device for the inner wall of a plastic-coated steel pipe, including a conveyor base, a support frame fixedly connected to the top of the conveyor base, an electric push rod fixedly connected to the top of the support frame, a fixed plate fixedly connected to the telescopic end of the electric push rod, and a protective cover fixedly connected to one side of the fixed plate.

A groove is formed inside the circular plate, and the inside of the groove is slidably connected to the surface of the arc-shaped mounting block. A spring is fixedly connected to the bottom of the arc-shaped mounting block, and the other end of the spring is fixedly connected to the inner wall of the groove.

[0009] The mounting groove is formed on the inner wall of the protective cover, and the interior of the mounting groove engages with the surface of the arc-shaped mounting block.

[0010] The plastic coating baking device for the inner wall of the plastic-coated steel pipe also includes a rotation limiting component, which is located inside the side wall of the protective cover.

[0011] The rotation limiting assembly includes a slider, a connecting block, a stop block, a second spring, a limiting block, and a limiting groove. The slider is slidably connected to the top of the protective cover, the connecting block is fixedly connected to the bottom of the slider, and the surface of the connecting block is slidably connected to the groove on the top of the protective cover. The stop block is fixedly connected to the bottom of the connecting block, and the surface of the stop block is slidably connected to the inner wall of the protective cover.

The limiting groove is opened on the side of the closed plate, and the inside of the limiting groove is engaged with the surface of the limiting block.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, the closed plate is held in hand, and the arc-shaped mounting block of the circular plate is aligned with the corner of the protective cover and pushed in. The closed plate is rotated, and the side wall of the protective cover squeezes the arc-shaped mounting block to slide inward along the groove and compress the spring. After rotating to the designated position, the arc-shaped mounting block is pushed into the mounting groove under the elastic force of the spring, and the axial positioning of the closed plate and the circular plate is completed. If the adjusting motor fails, the closed plate can be disassembled in time, and the adjusting motor inside the protective cover can be repaired to ensure the position adjustment of the heating rod and the baking effect of the device.

[0014] Slide the slider backward, and the connecting block will drive the stop block to slide backward. At the same time, the second spring will be compressed. The stop block will drive the limit block to slide into the protective cover. After the closing plate is installed, release the slider. Under the elastic force of the second spring, the limit block will be pushed into the limit groove to restrict the rotation of the closing plate and prevent the closing plate from being accidentally rotated or disassembled due to non-human factors, thus ensuring the protective effect of the closing plate on the regulating motor.
