[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Two embodiments provided by this utility model:

[0032] Example 1

[0033] Please see Figures 1 to 3 A guide-type cold rolling mill for processing steel strip includes a frame 100, within which a rolling system is installed. The rolling system includes work rolls, support rolls, and intermediate rolls. The work rolls are rolls that directly contact the strip and apply rolling deformation force. The support rolls support the work rolls and prevent them from excessively bending and deforming. The intermediate rolls are located between the work rolls and the support rolls and are used to further control the rigidity and shape of the rolling system. A guide structure 200 is provided on the frame 100, which corresponds to the working area of ​​the work rolls within the frame 100. The steel strip entering the frame 100 first passes through the guide structure 200 and then enters the working area of ​​the work rolls within the frame 100 for processing.

[0034] The guide structure 200 includes a support plate 201, two sliding plates 202, and two threaded screws 204. The support plate 201 is fixedly mounted on the frame 100. Two sliding plates 202 are symmetrically and movably mounted on the support plate 201. A slider 207 is fixedly mounted at the bottom end of each sliding plate 202. The slider 207 can slide within a groove 2011 opened on the support plate 201. The slider 207 is T-shaped and fits into the groove 2011. When the sliding plate 202 moves along the support plate 201, the slider 207 slides correspondingly within the groove 2011. The T-shaped slider 207 slides stably within the groove 2011, thus maintaining the stable movement of the sliding plate 202. The groove 2011 is closed at both ends, preventing the slider 207 from disengaging from the groove 2011. The tops of the two shift plates 202 are respectively threaded into the two threaded sections of the positive and negative threaded screws 204. One end of the positive and negative threaded screws 204 is powered by a stepper motor 205 fixedly mounted on the frame 100. The stepper motor 205 drives the positive and negative threaded screws 204 to rotate. The stepper motor 205 is selected and used by the technical personnel of this profession according to the actual situation. Clamping blocks 203 are fixedly mounted on opposite sides of the two shift plates 202. The clamping blocks 203 are U-shaped. According to the width of the steel strip in the working area of ​​the working roller inside the frame 100, the stepper motor 205 drives the positive and negative threaded screws 204 to rotate, and the two shift plates 202 move relative to each other or away from each other along the support plate 201. The distance between the two clamping blocks 203 is adjusted to accommodate the steel plate passing between the two clamping blocks 203 and to limit the passage of the steel plate.

[0035] This utility model, by setting up a support plate 201, a moving plate 202, a clamping block 203, a positive and negative threaded screw 204, a stepper motor 205, and a slider 207, has the advantages of guiding and limiting the steel strip entering the frame 100, and can adaptably adjust the guiding and limiting width according to the width of the steel strip, thus solving the problem that the steel strip entering the main frame is affected by the deviation due to the conveying process.

[0036] Example 2

[0037] Based on the technical content of Embodiment 1 above, another embodiment is proposed. Please refer to [link / reference]. Figure 2 , Figure 4 and Figure 5 A cold rolling mill for processing guide-type steel strips, wherein a support block 206 is connected to the bottom transverse end of a clamping block 203 via a telescopic rod 208, and a spring 209 is provided between one end of the support block 206 and the bottom transverse end of the clamping block 203. The two ends of the spring 209 are fixedly connected to one end of the support block 206 and the bottom transverse end of the clamping block 203, respectively. The elastic coefficient of the spring 209 shall be selected and used by the technical personnel in this field according to the actual situation.

[0038] This utility model, by setting up a support block 206, a telescopic rod 208 and a spring 209, has the advantage of providing constant support for the passing steel belt, so that the passing steel belt is adequately supported.

[0039] A support pad A210 is provided on the inner wall of the clamping block 203, and a support pad B211 is provided on the upper surface of the support block 206; both support pads A210 and B211 have arc-shaped cross sections, and can be made of wear-resistant rubber material. When the steel strip passes through, support pads A210 and B211 together support the passing steel strip, and the arc-shaped surfaces in contact with the steel strip facilitate its passage.

[0040] A retaining strip A212 is fixedly installed on the inner wall of the clamping block 203. The retaining strip A212 engages with the retaining groove A2101 opened on the support pad A210. A retaining strip B213 is fixedly installed on the upper surface of the support block 206. The retaining strip B213 engages with the retaining groove B2111 opened on the support pad B211. The cross-sections of both retaining strip A212 and retaining strip B213 are fan-shaped.

[0041] This utility model, by setting up a locking strip A212, a locking groove A2101, a locking strip B213, and a locking groove B2111, has the advantage that the locking strip A212 and the locking groove A2101, and the locking strip B213 and the locking groove B2111, make the support pads A210 and B211 detachable, which facilitates the replacement of excessively worn support pads A210 and B211.

[0042] Working principle: According to the width of the steel strip, the stepper motor 205 drives the positive and negative thread screws 204 to rotate. The two moving plates 202 move relative to or away from each other along the support plate 201. The slider 207 moves along the slide groove 2011. The two clamping blocks 203 move relative to or away from each other. The two support blocks 206 remain in contact. The spring 209 changes the degree of compression, and the telescopic rod 208 changes its length accordingly. The steel strip passes between the two clamping blocks 203. The bottom transverse section of the clamping block 203 and the support block 206 cooperate to support the steel strip and convey the steel strip into the working area of ​​the working roller in the frame 100 for processing.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
