[0032] The embodiment of the application discloses a heat treatment device for roller processing. Referring to Figure 1 and Figure 2 A heat treatment device for roller processing comprises a heating cover 1 with one end blocked, an opening 11 at the other end of the heating cover 1, and an electric heating tube (not shown in the figure) mounted on the inner side wall of the heating cover 1. The heating cover 1 is provided with an installation door 2 vertically arranged and blocking the opening 11 near the opening 11. A moving hole 12 corresponding to the installation door 2 is formed in the upper side of the heating cover 1 near the installation door 2, and the installation door 2 is slidably connected with the heating cover 1 through the moving hole 12.

[0033] Referring to Figure 2 and Figure 3The lower side of the heating cover 1 is provided with a mounting table 3, and the side wall of the mounting table 3 is abutted and fixedly connected with the inner side wall of the heating cover 1. The upper side of the mounting table 3 is provided with a mounting plate 31 which is horizontal and arranged along the length direction of the heating cover 1. The lower side of the mounting plate 31 is fixedly connected with a sliding block 311, and the upper side of the mounting table 3 is provided with a sliding groove 32 which is arranged along the length direction of the mounting plate 31. The sliding block 311 is inserted into the sliding groove 32 and is in sliding connection with the mounting table 3. The upper side of the mounting table 3 is rotatably connected with a driving lead screw 33 through insertion, and the driving lead screw 33 passes through the sliding block 311 and is in threaded connection with the sliding block 311. The end of the driving lead screw 33 away from the mounting door 2 is provided with a first motor 34 which is inserted into and fixedly connected with the side wall of the heating cover 1.

[0034] Referring to Figure 1 and Figure 2 , the upper side of the mounting plate 31 is provided with a plurality of support frames 4 which are symmetrically arranged on both sides of the mounting plate 31. The upper end of each support frame 4 is provided with an installation groove 41 which is open upward and whose width in the vertical direction gradually increases upward (not shown in the figure). When the roller is placed on the oppositely arranged support frames 4, the roller is parallel to the width direction of the mounting plate 31 and the lower side of the roller does not contact the upper side of the mounting plate 31.

[0035] The first motor 34 drives the driving lead screw 33 to rotate and drives the sliding block 311 to move along the sliding groove 32. At this time, the mounting plate 31 moves with the sliding block 311 until the support frames 4 on the mounting plate 31 are completely located outside the heating cover 1. The rollers are sequentially placed on the oppositely arranged support frames 4. The shape of the installation groove 41 is such that the side wall on the upper side of the installation groove 41 guides the end portion of the roller until the placement of the roller is completed. At this time, the first motor 34 drives the driving lead screw 33 to reverse and drives the mounting plate 31 to completely enter the heating cover 1. The heating cover 1 is blocked by the mounting door 2, and the roller is heated by the electric heating pipe. Since the lower side of the roller does not contact the mounting plate 31, the lower side of the roller is heated.

The connecting rod 23 is rotatably connected with the inner side wall of the upper side of the heating cover, and the end of the connecting rod 23 away from the gear 22 is provided with a belt 24 which connects the driving lead screw 33 close to the first motor 34.

[0037] ​The driving screw 33 rotates and drives the gear 22 to rotate through the belt 24 and the connecting rod 23, at this time, the rack 21 moves along the driving hole 121 under the driving of the gear 22 and drives the installation door 2 to move in the vertical direction, when the installation plate 31 moves to the inside of the heating cover 1 close to one end of the installation door 2, the installation door 2 completely opens the heating cover 1, facilitating the movement of the installation plate 31, and when the installation plate 31 moves to completely enter the heating cover 1, the installation door 2 blocks the heating cover 1, facilitating timely opening or closing of the heating cover 1.

[0038] With reference to Figure 2 and Figure 3 The vertically arranged heating plates 5 are arranged on both sides of the support frame 4, the side of the heating plate 5 close to each other is arranged as an upward and away from each other inclined slope, and the side of the oppositely arranged heating plates 5 is arranged as an arc-shaped recess from both sides to the middle and away from each other. The lower side of the heating plate 5 is slidably connected with the installation plate 31, and the installation plate 31 is provided with a moving piece 51 for driving the oppositely arranged heating plates 5 to move away from or close to each other.

[0039] The moving piece 51 comprises a bidirectional screw 511 penetrating through the lower side of the oppositely arranged heating plates 5 and threadedly connected with the corresponding heating plate 5, the bidirectional screw 511 is arranged along the length direction of the installation plate 31 and rotatably connected with the upper side of the installation plate 31, and the end portions of the adjacent bidirectional screws 511 are fixed to each other, and the end portion of the bidirectional screw 511 away from the installation door 2 is provided with a second motor 512 fixedly connected with the installation plate 31.

[0040] When placing the roller, the heating plate 5 is driven to move away from the corresponding support frame 4 by the second motor 512 and the bidirectional screw 511, reducing the possibility of the roller deviating and damaging the heating plate 5 under the action of external force, when the roller is placed on the support frame 4, the heating plate 5 is driven to move close to each other, facilitating heating of the lower side of the roller, at this time, the electric heating pipe on the heating cover 1 heats the upper side of the roller, so that the side wall of the roller can be heated.

[0041] The arc-shaped and inclined side wall of the heating plate 5 is adapted to the side wall of the roller, so that the distance between each part of the side wall of the heating plate 5 and the side wall of the roller is equal, facilitating uniform heating of the side wall of the roller.

[0042] The implementation principle of the heat treatment device for roller processing is that the roller is placed on the oppositely arranged support frames 4 in turn, and the installation plate 31 is driven to completely enter the heating cover 1, blocking the heating cover 1, the heating plates 5 are located on both sides of the roller and heat the roller, and the electric heating pipe heats the upper side of the roller, so that the side wall of the roller can be heated.
