The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-6, an oven for polytetrafluoroethylene columnar blanks comprises an oven body 1, an oven frame and a rail, wherein the rail extends from the outside of the oven body 1 to the inside of the oven body 1, the oven frame moves on the rail through rollers 12, the oven frame comprises a bottom plate 9, a handle 2, rollers 12 and a turntable 6, the handle 2 is fixed at one end of the bottom plate 9 facing the outside of the oven body 1, the rollers 12 are installed at four corners of the lower end of the bottom plate 9 through wheel carriers, the rail comprises a tip rail 10 and an auxiliary rail 7 which are integrally formed, the tip rail 10 is located on the upper portion of the auxiliary rail 7, the rollers 12 roll on the tip rail 10, the turntable 6 is installed on the bottom plate 9, a speed reducer 8 is fixed at the lower end of the bottom plate 9, a shaft of the speed reducer 8 is connected to the center of the bottom plate 9.

4 sliding blocks 15 are uniformly distributed on the edge of the rotary table 6, a circle of sliding groove 13 is formed in the upper end of the bottom plate 9, the four sliding blocks 15 slide in the sliding groove 13, and the contact surface of the sliding groove 13 and the sliding blocks 15 is smooth and can slide smoothly.

The junction of the track and the box door frame is provided with a gap for the oven frame to enter and exit the box body 1, the gap is provided with a detachable stop block 4, and the lower end of the stop block 4 is provided with a groove 42 matched with the tip track 10 in shape.

The edge of the upper end of the rotary table 6 is fixedly provided with a circle of air deflectors 5, one side of the inner wall of the box body 1 is provided with a fan 3, and the fan 3 blows air clockwise or anticlockwise towards the air deflectors 5 to assist in driving the rotary table 6 to rotate.

The length and the width of the stop block 4 are just clamped into the notch, the upper end of the stop block 4 protrudes towards one side of the box body 1 to form a protruding portion 41, and the width of the protruding portion 41 is equal to that of the stop block 4. In order to ensure the sealing performance of the oven, the periphery of the door frame of the oven is provided, so that the lower door frame can interrupt the track, a notch is cut in the door frame at the position, the stop block cut off from the notch can be inserted into the notch again, on one hand, the oven frame can smoothly enter and exit by the stop block, and on the other hand, the sealing effect can be realized.

The end of the track in the box 1 is fixed with a baffle 11. For preventing the oven rack from colliding against the inner wall of the oven.
