[0006] As a preferred embodiment of this utility model, the cleaning mechanism includes a cleaning cylinder fixedly connected to the top of the connecting frame. A drive screw is rotatably connected to both the front and back sides of the center of the cleaning cylinder. A sliding nut is threadedly connected to the outer wall of the drive screw and inside the cleaning cylinder. A sliding seat is fixedly connected to the outer wall of the sliding nut. A push plate is rotatably connected inside the sliding seat. A spiral spring is fixedly connected inside the push plate. An electromagnet is fixedly connected to the outer wall of the sliding seat near the push plate. Limit seats are fixedly connected to the top and bottom of the inner wall of the cleaning cylinder. A rotating roller is rotatably connected inside the limit seats. A rotary motor is fixedly connected to the outer wall of the limit seats at a position corresponding to the rotating roller. Scrapers are fixedly connected to both the front and back sides of the outer wall of the limit seats. A drive motor is fixedly connected to the outer wall of the cleaning cylinder at a position corresponding to the drive screw.

[0007] As a preferred embodiment of this utility model, the fixing base and the connecting frame are both made of stainless steel, and multiple sets of the connecting frame are provided. The connecting frame has an L-shaped structure design.

[0008] As a preferred embodiment of this utility model, the fixing base has an L-shaped structure design, and an anti-slip rubber pad is fixedly connected to the bottom of the fixing base. The controller is connected to the power plug by electrical connection.

[0009] As a preferred embodiment of this utility model, the cleaning cylinder, the sliding seat, and the limiting seat are all made of aluminum alloy. The pushing plate extends through and beyond the sliding seat. The limiting seat has a U-shaped structure design. The spiral spring is fixedly connected to the sliding seat, the rotary motor is fixedly connected to the rotary roller, and the drive motor is fixedly connected to the drive screw.

[0010] As a preferred embodiment of this utility model, the push plate is made of stainless steel, and a silicone pad is fixedly connected to the outer wall of the push plate.

[0013] Through the above technical solution, the anti-slip rubber pad can increase the friction between the rotating roller and the stainless steel seamless tube, preventing the stainless steel seamless tube from slipping on the rotating roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a heat treatment device for seamless stainless steel tubes is provided. The cleaning mechanism in the device is used to clean the seamless tubes. The seamless tubes are inserted into the cleaning cylinder, where the rotating roller supports them. The controller turns off the electromagnet, so the electromagnet no longer attracts the push plate. The spiral spring drives the push plate to rotate outward, and the outwardly rotating push plate presses against the seamless tube. The controller starts the drive motor and the rotary motor. The rotary motor drives the seamless tube to rotate through the rotating roller. The scraper scrapes off the debris attached to the seamless tube. At the same time, the drive motor drives the drive screw to rotate. The rotating drive screw drives the sliding nut to move the sliding seat and the push plate inward. The push plate moves the seamless tube inward together, thus pushing the cleaned seamless tube into the heat treatment furnace. This solves the problem that existing heat treatment devices cannot clean the incoming seamless tubes, causing debris on the outer wall to easily affect the heat treatment effect.
