[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 2, An embodiment provided by the present utility model: A roll heat treatment device, including a heat treatment chamber 1, the heat treatment chamber 1 can heat the roll for heat treatment. A feeding component is arranged on the right part of the heat treatment chamber 1. The feeding component includes a guide rail 8. The guide rail 8 can now make the sliding plate 7 slide only linearly within a fixed distance. The upper part of the guide rail 8 is slidably connected with a sliding plate 7. The sliding plate 7 can support the support plate 5 to drive the roll to enter and exit the heat treatment chamber 1 for blanking. An electric pulley is arranged at the lower part of the sliding plate 7 to slide horizontally and linearly on the guide rail 8. A blocking block 2 is in contact with the left part of the sliding plate 7. The blocking block 2 can now make the relative position of the support plate 5 and the sliding plate 7 fixed. The lower part of the left end of the guide rail 8 is fixedly connected to the lower part of the left end of the heat treatment chamber 1. The left part of the blocking block 2 is fixedly connected to the side part of the right end of the heat treatment chamber 1. The heat treatment chamber 1 is now relatively fixed at the position of the blocking block 2. Fixed brackets 3 are fixedly connected to the front and rear ends of the feeding component. The fixed brackets 3 can support and fix the support plate 5, which is convenient for the roll to be lifted and lowered by a crane and a steel chain. The side end of the fixed bracket 3 is in contact with the side end of the sliding plate 7. By sliding the support plate 5 from the upper end of the sliding plate 7 to the fixed bracket 3, the roll can be replaced, and the roll can be lifted by a crane while the roll is being heat-treated. This way improves the work efficiency.

[0033] Refer to Figure 1 , Figure 3 and Figure 4, a slope block 10 is slidably connected inside the fixed bracket 3. The slope block 10 can slide into the inside of the fixed bracket 3 under the extrusion of the positioning block 12, so that the positioning block 12 can slide into the upper end inside of the fixed bracket 3. There are two groups of slope blocks 10, and the two groups of slope blocks 10 are elastically connected by a first spring 11. The extrusion of the first spring 11 can make the slope block 10 slide into the side end inside of the positioning block 12 to keep the support plate 5 relatively fixed. The two ends of the first spring 11 are respectively fixedly connected to the side ends of the two groups of slope blocks 10 in contact. The extrusion of the first spring 11 makes the slope block 10 can be fixed inside the positioning block 12. The outside of the slope block 10 is slidably connected with a positioning block 12. The positioning block 12 can be restricted by the fixed bracket 3 and the sliding plate 7 to only slide horizontally in a straight line, so that the roller can only slide horizontally in a straight line accordingly. The outside of the positioning block 12 is slidably connected inside the upper end of the fixed bracket 3. The upper part of the positioning block 12 is fixedly connected with a support plate 5. The support plate 5 can support the Y-shaped frame 6 to keep it fixed and can slide horizontally under the push of a push rod or other devices. The lower part of the support plate 5 is in contact with the top of the fixed bracket 3. The top of the support plate 5 is fixedly connected with a Y-shaped frame 6. The Y-shaped frame 6 can support and keep the roller horizontal and stable. The left end side of the slope block 10 is in contact with a trapezoidal block 9. A square groove is provided on the left part of the slope block 10, so that the slope of the trapezoidal block 9 can extrude the square groove to make the slope block 10 slide into the inside of the fixed bracket 3 to release the limit. The outside of the trapezoidal block 9 is slidably connected inside the fixed bracket 3. The left part of the trapezoidal block 9 is fixedly connected with a connecting rod 16. The connecting rod 16 can facilitate the sliding of the trapezoidal block 9. The outside of the connecting rod 16 is slidably connected inside the left end of the fixed bracket 3. The connecting rod 16 and the trapezoidal block 9 are restricted by the fixed bracket 3 to only slide horizontally in a straight line within a fixed distance. The left end side of the connecting rod 16 is in contact with a gear position assembly.

[0034] Refer to Figure 1 , Figure 3 and Figure 5, the gear position assembly includes a stop block 4. The stop block 4 can block to prevent the connecting rod 16 from sliding out of the interior of the fixed bracket 3, so that the positioning block 12 can be kept in a slidable state, which facilitates the feeding. The side of the stop block 4 is in contact with the left end side of the connecting rod 16. A connecting block 14 is fixedly connected to the right part of the stop block 4. The connecting block 14 enables the stop block 4 to slide horizontally and linearly relative to the fixed bracket 3 within a fixed distance. A fixed column 15 is slidably connected to the middle interior of the connecting block 14. Both ends of the fixed column 15 are fixedly connected to the interior of the side end of the fixed bracket 3. The fixed column 15 is restricted by the fixed bracket 3 to remain fixed. In this way, the connecting block 14 can only slide horizontally. The right part of the connecting block 14 is elastically connected to the interior of the left end of the fixed bracket 3 through a second spring 13. The extrusion of the second spring 13 can make the stop block 4 slide leftward to block the connecting rod 16. One end of the second spring 13 is fixedly connected to the side end of the connecting block 14, and the second spring 13 is kept in a state of extruding the connecting block 14 under the extrusion of the fixed bracket 3. The other end of the second spring 13 is fixedly connected to the interior of the side end of the fixed bracket 3.

[0035] Working principle: When the roll has been heat-treated in the heat treatment chamber 1 for a sufficient time, the heat treatment chamber 1 can be opened. Subsequently, the electric pulley at the lower end of the sliding plate 7 can be used to make the sliding plate 7 slide out of the interior of the heat treatment chamber 1. Then, the side end connecting rod 16 of the fixed bracket 3 supporting one end of the roll can be slid into the interior of the fixed bracket 3. The trapezoidal block 9 can slide into the side groove inside the inclined plane block 10. At this time, the inclined plane block 10 slides out of the interior of the side end of the positioning block 12 and squeezes the first spring 11. And the stop block 4 and the connecting block 14 slide leftward under the extrusion of the second spring 13, so that the connecting rod 16 no longer slides. Subsequently, the support plate 5 can be pushed by the push rod to make it squeeze the support plate 5 at the upper end of the sliding plate 7 and slide into the interior of the fixed bracket 3 at the other end. And the inclined plane of the inclined plane block 10 is squeezed and slides into the interior of the fixed bracket 3 to squeeze the first spring 11. Subsequently, the inclined plane block 10 slides into the interior of the positioning block 12 under the extrusion of the first spring 11 to keep the support plate 5 sliding out on the sliding plate 7 and the roll fixed. Then, the stop block 4 and the connecting block 14 can be slid back to their original positions to squeeze the second spring 13. At this time, the inclined plane block 10 slides out under the extrusion of the first spring 11, and the trapezoidal block 9 and the connecting rod 16 slide back to their original positions. Subsequently, the push rod hoist and the iron chain can lift the heat-treated roll for quenching.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
