[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a roller heat treatment equipment, including a treatment box 1, which is the main part of the whole equipment, used to accommodate the roller and perform heat treatment. The bottom surface of the treatment box 1 is fixedly connected with four groups of symmetrically arranged support legs 11, and the four groups of support legs 11 are used to support and stabilize the equipment. The side wall of the treatment box 1 is hinged with a sealed door 12, and the side of the sealed door 12 is fixedly connected with a handle. The sealed door 12 is used to open and close the inlet and outlet of the treatment box 1, so as to facilitate the placement and removal of the roller. The inner wall of the treatment box 1 is provided with multiple groups of array-distributed heating plates 2, and the heating plates 2 are used to achieve the heating of the roller. Two groups of symmetrically arranged tooth plates 3 are fixedly connected to the inner wall of the treatment box 1, and the tooth plates 3 are used to cooperate with the tooth disc 48 in the fixing component 4, so as to realize the rotation of the tooth disc 48. The interior of the treatment box 1 is provided with a fixing component 4, and the fixing component 4 is used to fix multiple groups of rollers, so as to achieve simultaneous heating of multiple groups of rollers and improve processing efficiency.

[0029] Reference Figure 2 - Figure 3The fixed assembly 4 includes a rotating shaft 41, one end of which is rotatably connected to the inner wall of the processing box 1, and the other end of the rotating shaft 41 penetrates and is rotatably connected to the surface of the processing box 1. The bottom surface of the processing box 1 is fixedly connected with a motor 410, and the output shaft of the motor 410 penetrates and is rotatably connected to the inner wall of the processing box 1. The output shaft of the motor 410 is fixedly connected to the bottom end of the rotating shaft 41. The rotating shaft 41 is used to drive the entire fixed assembly 4 to rotate, and cooperate with the heating plate 2 to achieve a uniform heating effect. The motor 410 is used to provide power for the rotating shaft 41 to rotate. The side wall of the rotating shaft 41 is provided with a slide groove 42, and the inner wall of the slide groove 42 is slidably connected with two groups of symmetrically arranged sliders 43. The shape of the slider 43 is a cross. The slide groove 42 is a slotted structure on the rotating shaft 41, which is used to install the slider 43 and enable the slider 43 to slide along the length direction of the rotating shaft 41. Each end of the slider 43 is fixedly connected to a support rod 46, and the end of the support rod 46 is fixedly connected to a disc 47. The support rod 46 is used to connect the slider 43 and the disc 47 together, so that the disc 47 and the slider 43 move synchronously. The surface of the disc 47 is rotatably connected to a toothed disc 48, which meshes with the toothed plate 3. The surface of the toothed disc 48 is used to fit with the end of the roller, and through the upper and lower groups of sliders 43 moving toward each other, multiple groups of support rods 46 and the disc 47 and toothed disc 48 can clamp and fix multiple groups of rollers, thereby improving the processing efficiency. And through the toothed disc 48 meshing with the toothed plate 3, the rotating shaft 41 drives the toothed disc 48 to rotate, and the toothed disc 48 itself will also rotate, so that the rollers on the surface of the toothed disc 48 rotate accordingly, improving the uniformity of the rollers during the heating process. A positioning cone 49 is fixedly connected to the surface of the toothed disc 48. The positioning cone 49 is used to be inserted into the hole at the end of the roller to achieve positioning of the roller and improve the stability of the roller during processing.

[0030] Reference Figure 2 - Figure 3 The two sets of sliders 43 are threadedly connected by a bidirectional threaded rod 44, one end of which is rotatably connected to the inner wall of the slide groove 42, and the other end of which is fixedly connected to a rotating wheel 45, which penetrates and is rotatably connected to the top of the rotating shaft 41. The rotating wheel 45 is used to facilitate the rotation of the staff, thereby controlling the bidirectional threaded rod 44 to rotate forward or reverse, thereby driving the two sets of sliders 43 to move toward or away from each other, thereby clamping and fixing the rollers.

[0031] Working principle: When in use, the operator opens the sealed door 12 of the processing box 1, places the roller to be processed on the surface of each toothed disc 48 in turn, and docks the hole at the end of the roller with the positioning cone 49 to realize the positioning of the roller. By rotating the rotating wheel 45, the bidirectional threaded rod 44 drives the two groups of sliders 43 to move toward each other, so that multiple groups of support rods 46, discs 47, and toothed discs 48 can clamp and fix multiple groups of rollers, thereby improving the processing efficiency. Then close the sealed door 12, and heat the multiple groups of rollers through the heating plate 2. During the heating process, the rotating shaft 41 drives the slider 43, disc 47, and toothed disc 48 to rotate by starting the motor 410, and the toothed disc 48 is meshed with the toothed plate 3 during the rotation process, so that the toothed disc 48 drives the roller to rotate, thereby improving the uniformity of the roller during the heating process. When the roller reaches the required heating temperature, the operator stops the operation of the motor 410 and the heating plate 2, the heating process ends, and opens the sealed door 12 to take out the roller that has been heated.
