Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a stainless steel pipe coating equipment. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, mainly composed of metallic elements such as iron, chromium, and nickel. It possesses corrosion resistance, high-temperature resistance, and good mechanical properties, and is widely used in construction, chemical industry, and machinery manufacturing. Coating stainless steel pipes is primarily for surface protection. During transportation, storage, and processing, stainless steel pipes are susceptible to scratches, wear, and corrosion. Coating acts as a barrier, preventing external factors from damaging the pipe surface, maintaining its appearance and performance, while also reducing cleaning and maintenance costs and extending the service life of the stainless steel pipe.

[0003] Plastic coating is a common coating method for stainless steel pipes. First, the surface of the stainless steel pipe is pre-treated, thoroughly cleaned to remove rust and oil, laying a good foundation for coating adhesion. Then, plastic powder or liquid coating is evenly applied to the pipe surface using spraying or dipping. It is then placed in a curing oven at 200-240℃ to cross-link the coating into a strong protective layer. However, due to gravity, dripping and accumulation at the lower end of the steel pipe can easily occur during operation, resulting in an excessively thick coating. Therefore, rotary coating or the addition of a flow guiding device is often used to dynamically disperse the coating and optimize airflow, balancing the coating thickness and ensuring corrosion resistance and suitability for use. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a stainless steel pipe coating equipment that rotates the pipe after coating and immediately heats and shapes it to achieve a more uniform coating.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a stainless steel pipe coating equipment, comprising:

[0006] The support includes a base plate, a vertical support plate, and a bracket. The bracket is fixedly installed on the rear side above the base plate, and the vertical support plate is fixedly installed on one end above the base plate and located on the front side of the bracket.

[0007] An air shaft is rotatably connected to a vertical support plate and is driven to rotate by a geared motor fixed to the vertical support plate.

[0008] The plastic-coated frame, located above the base plate and driven by a screw driver fixed on the bracket, includes a main support rod, an L-shaped support rod, and an L-shaped support plate. The main support rod is connected to the screw driver, and an injection molding frame is fixedly mounted on its extended end. The L-shaped support rod is fixedly mounted on one side of the main support rod, and a heater is fixedly mounted on its extended end. The L-shaped support plate is fixedly mounted on the L-shaped support rod, and a fan is fixedly mounted on it, with the fan positioned directly above the heater.

[0009] Furthermore, the bracket includes a heightening block and a carrier plate. The carrier plate is located above the base plate and parallel to the base plate. There are two heightening blocks, which are respectively located below the carrier plate near both ends. The upper and lower walls of the heightening blocks are fixedly connected to the carrier plate and the base plate, respectively.

[0010] Furthermore, a guide seat is fixedly provided above the base plate, and a guide block is fixedly provided below the main support rod, with the guide block slidably mounted on the guide seat.

[0011] Furthermore, the injection molding frame includes an arc-shaped hollow plate, with a plurality of injection nozzles evenly spaced on the inner side of the arc-shaped hollow plate and an injection port in the middle of the outer side.

[0012] Furthermore, the heater is inverted U-shaped, and the air shaft, injection molding frame, and heater center axis are arranged to coincide.

[0013] Compared with existing technologies, this invention has the following advantages: The equipment is equipped with an air-expansion shaft driven by a geared motor to fix the stainless steel tube. The coated stainless steel tube can rotate stably, which makes the coated plastic more evenly distributed on the surface of the stainless steel tube and avoids uneven coating thickness caused by static conditions. After coating, the heater and fan can quickly heat the stainless steel tube, allowing the plastic coating to better adhere to the surface of the stainless steel tube and dry in time while heated. The special shape design of the heater can heat the stainless steel tube from all directions, ensuring uniform heating of all parts and further promoting the uniform distribution of the plastic coating. Moreover, the coating and heating shaping processes are closely linked, reducing the possibility of uneven coating that may occur while waiting for heating. Under the dual action of rotation and heating, the plastic coating can adhere more evenly to the surface of the stainless steel tube, thereby effectively improving the quality and effect of the coating.
