Description

Technical Field

[0001] The utility model belongs to the technical field of strip steel production, in particular to a vertical looper strip steel anti-pollution baffle device for a cold rolling mill. Background Art

[0002] Vertical loopers are often used to store steel strip in cold rolling mills, including continuous annealing lines, galvanizing lines, and galvanized lines. When a production line encounters an emergency, the amount of stored strip can be adjusted by raising or lowering the upper looper rollers. The wire ropes and bearing seats in the looper carry lubricating oil and particulate contaminants. As the upper looper rollers rise and fall, and the wire ropes rotate, these oily or particulate contaminants fall onto the upper and lower rollers. Once the rollers contact the strip, they contaminate the strip. Cold rolling mills have strict requirements for environmental cleanliness, and no contaminants are allowed on the strip surface. This can impact downstream production processes and affect product quality. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to better understand the purpose, structure and function of the present invention, the present invention is clearly and completely described below in conjunction with the accompanying drawings.

[0019] like Figure 1-Figure 4 The figure shows a cold rolling mill vertical looping strip steel anti-fouling baffle device, comprising an upper row of looping rollers 1 and a lower row of looping rollers 2. An upper baffle 3 is provided above the upper row of looping rollers 1, and a lower baffle 4 is provided above the lower row of looping rollers 2. The upper baffle 3 and the lower baffle 4 are used to prevent the steel wire rope 13, oil stains on the bearing seat and other particulate pollutants from falling onto the upper roller of the upper row of looping rollers 1 and the lower roller 6 of the lower row of looping rollers 2, respectively. Figure 1 and Figure 4As shown, the strip 15 is alternately passed around the upper roller and the lower roller 6 in sequence for storage. The upper baffle 3 is located above the upper roller and does not affect the passage of the strip 15, while the lower baffle 4 does. Therefore, the lower baffle 4 includes several split plates 5, and each split plate 5 corresponds to a lower roller 6 of the lower row of looper rollers 2; that is, the lower baffle 4 adopts a split design, and the space between the two split plates 5 is reserved for the strip 15 to pass through.

[0020] Furthermore, the lower part of the upper baffle 3 is provided with a plurality of pillars 7, and the lower part of the pillars 7 is connected to the upper steel frame 8 of the upper row of looping rollers 1; the lower part of the split plate 5 is provided with a plurality of pillars 2 9, and the lower part of the pillars 2 9 is connected to the lower steel frame 10 of the lower row of looping rollers 2; Figure 2 and Figure 3 As shown. Strut 1 7 and upper baffle 3, and strut 2 9 and sub-panel 5, can be integrally formed, specifically by welding. The lower portions of strut 1 7 and strut 2 9 are bolted to the upper steel frame 8 and lower steel frame 10, respectively, to facilitate replacement of the upper baffle 3 and sub-panel 5. In this embodiment, at least four struts 1 7 are provided below the upper baffle 3, located at the four corners of the lower portion. Each sub-panel 5 is also provided with at least four struts 2 9, located at the four corners of the lower portion.

[0021] In addition, in this embodiment, a correction roller 11 is provided below the lower row of looper rollers 2. The correction roller 11 is connected to the strip steel 15 and is used to fine-tune the direction of the strip steel 15. This structure is commonly used in actual production in cold rolling mills and will not be described in detail here.

[0022] In this embodiment, an adjusting roller 12 assembly is provided above the upper row of looping rollers 1. A wire rope 13 is wound around the adjusting roller 12 of the adjusting roller 12 assembly. One end of the wire rope 13 is connected to the upper steel frame 8 of the upper row of looping rollers 1, and the other end is connected to the lower row of looping rollers 2 or the fixed frame 14. When the wire rope 13 is stretched, the wire rope 13 moves around the adjusting roller 12, and the upper row of looping rollers 1 rises and falls with the wire rope 13, thereby achieving the purpose of adjusting the upper row of looping rollers 1. Furthermore, the adjusting roller 12 assembly includes two adjusting rollers 12, which are respectively located at the upper ends of the upper row of looping rollers 1. The wire rope 13 wound around the adjusting rollers 12 is respectively connected to the two ends of the upper steel frame 8; this makes the upper row of movable rollers rise and fall more smoothly.

[0023] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
