[0028] Embodiment

[0029] In combination with Figures 1-5As shown in the figure, this embodiment provides a cold rolling continuous annealing unit device, which includes a roller 1, a roller shaft 2 and a cover plate. The inside of the roller 1 is a hollow structure, and the roller 1 is sleeved outside the roller shaft 2. The cover plate includes a first connecting portion 3 and a second connecting portion 4. The first connecting portion 3 and the second connecting portion 4 are connected by integral molding or welding. The cover plate plays a role in sealing and connecting. Among them, the second connecting portion 4 is a cylindrical structure with a through hole inside. The roller shaft 2 extends into the roller 1 through the through hole of the second connecting portion 4. And a second screw hole is provided on the second connecting portion 4, and a corresponding second mounting hole is provided on the roller shaft 2. The second fixing bolt 7 is passed through the second screw hole and the second mounting hole to realize the fixing effect of the second connecting portion 4 and the roller shaft 2. And a first screw hole 13 is provided on the first connecting portion 3 of the cover plate, and a first mounting hole 12 is provided at the end of the roller 1. The first mounting hole 12 communicates with the inside of the roller 1. By passing the first fixing bolt 6 through the first screw hole 13 and the first mounting hole 12, the fixing effect of the first connecting portion 3 and the roller 1 is realized. It should be noted that in order to adapt the first connecting portion 3 to the end of the roller 1, it is preferably to set the first connecting portion 3 as a circular structure. And the number of the first fixing bolts 6 and the second fixing bolts 7 is set according to the actual situation, and no excessive limitation is made here.

[0030] In this embodiment, a transmission thread portion 8 is provided on the outer surface of the roller 1. The rotation direction of the transmission thread portion 8 is the same as the rotation direction of the roller 1. Among them, the purpose of setting the transmission thread portion 8 is: on the one hand, it can increase the heat dissipation area and improve the heat dissipation effect; on the other hand, when the steel strip moves on the roller path, the force of the rotational motion can be converted into a propulsive force to promote the movement of the steel strip. In some preferred ways, the transmission thread portion 8 is provided on the outer surface of the barrel body of the roller 1, and a plurality of fixing convex portions 11 are provided at both ends of the roller 1, and a slot hole 10 is provided between two adjacent fixing convex portions 11. At least one first mounting hole 12 is provided on each fixing convex portion 11.

[0031] In some preferred ways, the connection position between the first connecting portion 3 and the second connecting portion 4 is an arc-shaped structure 14. When the cover plate is connected to the roller 1, the heat in the roller 1 can be buffered in the space between the arc-shaped structure 14 and the inside of the roller 1, avoiding the adverse impact on the deformation of the entire device due to excessive heat shock. And a plurality of heat dissipation holes 5 are provided at the position of the arc-shaped structure 14, and the heat that is not dissipated from the inside of the roller 1 can be dissipated through the heat dissipation holes 5 at both ends of the roller 1.

[0032] In some preferred embodiments, a limiting convex portion 9 is further provided at one end of the first connecting portion 3 away from the second connecting portion 4. The number of the limiting convex portions 9 is the same as that of the slot holes 10. Preferably, the number of the slot holes 10 and the limiting convex portions 9 is set to be 2-8. When installing the cover plate, each limiting convex portion 9 corresponds to a corresponding slot hole 10 for installation, which not only plays a role in installation guidance, but also plays a role in the sealing connection between the cover plate and the roller 1. Among them, the limiting convex portions 9 are arranged at intervals along the circumferential edge of the first connecting portion 3.

[0033] The working principle of this equipment is as follows:

[0034] When installing the roller 1, first sleuth the roller 1 outside the roller shaft 2, and then install a cover plate at each end of the roller shaft 2. Specifically, the roller shaft 2 passes through the inside of the second connecting portion 4 and the first connecting portion 3 until it extends outside the first connecting portion 3. Align any one of the limiting convex portions 9 provided on the second connecting portion 4 with any one of the slot holes 10 at the end of the roller 1, and install the limiting convex portion 9 inside the slot hole 10. Since the number of the limiting convex portions 9 is the same as that of the slot holes 10, the area of the butt joint circular end face between the second connecting portion 4 and the roller 1 is equal, and the interval between each limiting convex portion 9 is also equal to the interval between each slot hole 10. Therefore, as long as one of the limiting convex portions 9 is installed with the slot hole 10, the other limiting convex portions 9 and slot holes 10 will be directly installed in correspondence. Then, connect the first connecting portion 3 of the cover plate and the roller 1 by passing the first fixing bolt 6 through the first screw hole 13 and the first mounting hole 12; connect the second connecting portion 4 of the cover plate and the roller shaft 2 by passing the second fixing bolt 7 through the second screw hole and the second mounting hole, thereby connecting the roller 1, the roller shaft 2, and the cover plate.

[0035] In this embodiment, the roller 1 can be made of special rubber. The transmission thread portion 8 provided on the rubber enhances the adaptability of the roller structure to the strip steel, which can prevent the strip steel from slipping and shifting during operation. The softness property of the rubber will not cause the strip steel to wrinkle and is firm and durable, avoiding the occurrence of strip steel slipping; at the same time, it also effectively improves the surface quality of the product.

[0036] The above is only the embodiment of the present invention, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
