[0036] The intermittent outward pulling assembly 378 includes a rotating arm 3781, a connecting strip 3782, a pressure strip 3783, a connecting rod 3784, a docking strip 3785, a roller 3786, a supporting strip 3787 and a damper 3788. The rotating arm 3781 is connected to the rear side of the rotating shaft 376, the left side of the rotating arm 3781 is rotatably connected to the connecting strip 3782, the left side of the connecting strip 3782 is rotatably connected to the upper end of the pressure strip 3783, a connecting rod 3784 is inserted in the middle of the pressure strip 3783, and the connecting rod 3784 is rotatably connected to the inner part of the upper end of the guide shell 379, so as to ensure that the pressure strip 3783 can be pulled. To perform a tilting and pressing action, docking strips 3785 are installed on both sides of the outer end of the connecting rod 3784, and the docking strips 3785 are respectively installed on both sides of the outer end of the guide shell 379, and the docking strips 3785 on both sides can move synchronously with the connecting rod 3784, and the lower end of the docking strip 3785 is rotatably connected to a roller 3786, and the lower end of the roller 3786 is abutted against the supporting strip 3787, and three dampers 3788 are installed at the bottom of the supporting strip 3787 in sequence, and the elastic top effect of the three dampers 3788 can ensure the abutment effect of the supporting strip 3787 and the roller 3786 arranged at the lower end of the docking strip 3785.

[0037] Among them, the pressure strip 3783 is embedded in the middle of the upper end of the guide shell 379, and the lower end of the pressure strip 3783 is generally arranged in a round convex shape, ensuring that the pressure strip 3783 as a whole can achieve stable extrusion and external pull transmission cooperation.

[0038] Among them, the docking strips 3785 and the rollers 3786 are symmetrically arranged along both sides of the connecting rod 3784, and the installation direction of the docking strips 3785 on both sides is consistent with the pressure strip 3783 and is installed in an inclined direction, ensuring that when the pressure strip 3783 is pulled and pressed down, the docking strips 3785 on both sides can be pressed down synchronously.

[0039] Among them, the supporting bars 3787 are symmetrically embedded along both sides of the upper end of the supporting plate 372, and the upper ends of the supporting bars 3787 on both sides are arranged in the shape of inner grooves, ensuring that the supporting bars 3787 can stably contact with the lower end of the roller 3786 through the inner grooves opened at the upper ends.

[0040] Specifically, when the stainless steel material enters the heating furnace 3 by the roller conveyor 32 arranged at the upper end of the random rack 31 and is subjected to uniform heating by the electromagnetic heating coil 36 installed at the upper end of the rack 31, in order to ensure that the stainless steel material is heated evenly and fully, the overall transmission speed of the roller conveyor 32 is generally in a slow state. When the stainless steel material has completed the sufficient heating activity, in order to speed up the rapid discharge of the stainless steel material, the motor connected to the outside of the first driving wheel 373 can be driven to realize the rotation of the first driving wheel 373. As the first driving wheel 373 rotates, the first transmission belt 374 connected to the outside of the first driving wheel 373 will realize the rotation of the first driven wheel 375 connected to the right side, thereby connecting the first driven wheel 375 in the middle of the first driven wheel 375. The rotating shaft 376 of the rear end will realize the counterclockwise rotation of the rotating arm 3781 connected to the rear end. Through the counterclockwise rotation of the rotating arm 3781, the connecting strip 3782 connected to the outside will be used to pull the pressure strip 3783 connected to one side, that is, when the pressure strip 3783 is pulled, it can not only cooperate with the connecting rod 3784 connected to the middle part to drive the outer guide shell 379 to move right, but also, the pressure strip 3783 is pulled and tilted downward. In this way, when the heated stainless steel moves from the discharge end of the furnace body 33 into the guide shell 379, it will be pressed down and moved right by the pressure strip 3783, and the rapid rightward discharge activity will be realized to quickly move the heated stainless steel material out of the furnace body 33, so that the subsequent stainless steel material can quickly enter the heating position, thereby accelerating the overall heating efficiency.

[0041] At the same time, when the pressure strip 3783 is pulled and pressed down, the connecting rod 3784 installed in the middle of the pressure strip 3783 will realize the synchronous downward pressing of the docking strips 3785 installed on both sides of the outer end. Therefore, the rollers 3786 docked at the lower ends of the docking strips 3785 on both sides will squeeze the supporting strip 3787, so that the supporting strip 3787 moves downward as a whole, and squeeze the dampers 3788 installed at three locations at the bottom. With the rebound and upward assistance of the three dampers 3788, the supporting strip 3787 and the roller 3786 can be stably abutted and fitted. Therefore, through the sliding docking effect of the inner groove opened at the upper end of the roller 3786 and the supporting strip 3787, when the guide shell 379 is pulled as a whole and moves to the right along the upper end of the supporting plate 372, it can provide a stable fit for the moving support, thereby improving the stability of the rightward movement of the guide shell 379 and ensuring the stability of the rapid discharge state of the stainless steel material.

The second driving wheel 37102 is connected to the outer end of one side of the rotating shaft 376, and the second driving wheel 37102 is externally connected to the second conveyor belt 37103.

The right side of the second conveyor belt 37103 is connected to the second driven wheel 37104 The rear side of the second driven wheel 37104 is connected with a rotating plate 37105, and the outer end of the rotating plate 37105 is rotatably connected with a connecting ring 37106, the connecting ring 37106 is connected to one side of the pull rope 37107, and the other side of the pull rope 37107 is connected to the spring 37109.

[0044] Among them, the first connecting plate 37113 and the second connecting plate 37117 are arranged opposite to each other up and down, and the two sides of the second connecting plate 37117 are respectively slidably docked with the inner sides of the movable frame 37112, so that the overall position of the second connecting plate 37117 can be adjusted up and down to correspondingly change the distance between the second connecting plate 37117 and the first connecting plate 37113.

[0045] Specifically, after the stainless steel material is quickly moved out by the downward pressing and right pulling of the pressure bar 3783, the stainless steel material will move into the second shell 37101 and connect with the guide roller provided at the lower end of the second shell 37101 to improve the transmission stability of the stainless steel material. When the stainless steel material enters the second shell 37101, the second driving wheel 37102 installed on the outside of the rotating shaft 376 will rotate simultaneously, and through the cooperation of the second conveyor belt 37103, the stainless steel material will be moved into the second shell 37101 and connected with the guide roller provided at the lower end of the second shell 37101 to improve the transmission stability of the stainless steel material. The second driven wheel 37104 connected to the right side rotates, and thus, the rotating plate 37105 connected to the rear side of the second driven wheel 37104 will rotate counterclockwise to rotate in the same direction as the rotating arm 3781. When the rotating plate 37105 rotates, the connecting ring 37106 connected to the outside of the rotating plate 37105 rotates, which will realize the pulling of the pull rope 37107 connected to the outer end.

When the spring 37109 pulls the pull rope 37107 back through its own elastic force, the turntable 37108 will rotate clockwise.
