2. the service cycle of the steering roller is prolonged, and the cost is saved;
3. and contract delivery is completed, the batch quality accident rate is reduced, and the user requirements are met.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The utility model is further described with reference to the drawings and the detailed description. In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the claimed embodiments. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
In the following embodiments, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the embodiments of the present application can be understood by those skilled in the art according to specific situations.
For better description, the front and back are set based on the traveling direction of the strip, i.e., the right side of fig. 1 is the front, and vice versa. It is to be understood that the terms "central," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," "end," "side," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the claimed embodiments and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the claimed embodiments.
The utility model improves the front steering roller area of the acid pickling production line outlet or the galvanized outlet of the acid pickling and galvanizing combined unit. The undisclosed part is the prior art, and is suitable for the existing pickling line or pickling and galvanizing combined machine set, because of different types of the production lines and slightly different structures, the connection mode and the control mode of the roller set and the production line main body, and other parts of the pickling line or pickling and galvanizing combined machine set are not described in detail herein.
As shown in figure 1, the utility model comprises a guide plate table 2 and a roller set, wherein the roller set comprises a steering roller 1, a coiling press roller 3 and a coiling front supporting roller 4.
The guide plate table 2 is used for supporting a steel plate and assisting strip steel to penetrate through a strip head. A nylon plate is fixed on the guide plate table 2 by bolts. The bolts fixed on the guide plate table 2 are easy to bulge after a long time along with the vibration of the guide plate table in the production process, and scratch defects are generated when a strip steel head penetrates a strip and a strip tail is thrown. Normal production, the strip steel is in a tight state, and no scratch is generated. In order to prevent the bolt from protruding, the bolt cap is required to be 1mm lower than the guide plate table nylon plate. And a thread glue layer is arranged between the bolt and the nylon plate. In order to facilitate point inspection, the bolt hole is provided with a color mark, and the color mark is red paint.
And a coiling front carrier roller 4 is arranged at the front end of the guide plate table 2. The front reeling carrier roller 4 is a steel roller, the diameter of the front reeling carrier roller is 80mm, the contact wrap angle of the strip steel and the steering roller 1 is increased, the contact area of the strip steel with the guide plate table 2 and the roller set is reduced, and the probability of scratching the strip head and the strip tail is reduced.
A steering roller 1 is arranged below the front coiling front carrier roller 4, the steering roller 1 is a chrome-plated steel roller, and the roller diameter is 500 mm.
And a coiling press roller 3 is arranged above the front part of the coiling front carrier roller 4. When the strip steel is threaded, the coiling press roll 3 is pressed down to form a clamping and conveying device with the steering roll 1, and the strip steel is driven to move forwards for coiling. The coiling press roll 3 presses down when the strip head of the strip steel just passes through the steering roll 1, so that the strip steel is prevented from deviating, and meanwhile, the coiling press roll 3 and the steering roll 1 form a clamping and conveying device to drive the strip steel to move forwards for coiling. After the tape head is wound for 4 turns on the reel, the winding pressure roller 3 is opened. When the roll division is to be performed, the winding pressure roller 3 is pressed down again before the flying shear cuts. The above working cooperation between the steering roll 1 and the winding pressure roll 3 is the prior art, and the control method thereof will not be described herein.
It should be noted that the present embodiment is not described in detail, and is a technique known in the art.
While specific embodiments of the utility model have been described above for purposes of illustration, it will be apparent to those skilled in the art that various obvious changes can be made without departing from the spirit and scope of the utility model.
