Description

Technical Field

[0001] The utility model belongs to the field of square tube production, in particular to a steel strip guide rolling structure. Background Art

[0002] After the square tubes are produced, they will be bundled with steel straps to facilitate the movement and transportation of the square tubes. Since the strapping steel straps are wound into rolls, the steel straps are cut into appropriate lengths from the steel strap rolls during packaging, and then the cut steel straps are wrapped around the square tube stacks. Tools are used to rivet or weld the ends of the steel straps to complete the packaging of the square tube stacks. In actual operation, it is found that since the steel straps are pre-wound into rolls, bending deformation is formed. Even if the steel straps are pulled tightly when the ends are connected, it is difficult to completely eliminate the bending deformation of the steel straps. During the bundling process, it is difficult for the steel straps to adhere closely to the surface of the square tube stacks, which makes it difficult to bundle and tighten the steel straps, affecting the bundling and packaging effect of the square tube stacks. Utility Model Content

[0003] In view of this, the utility model aims to propose a steel belt guiding rolling structure to realize the rolling of the steel belt for square tube bundling, eliminate the bending deformation of the steel belt, improve the fit between the steel belt and the surface of the square tube stack, and ensure the stability of the square tube stack bundling and packaging.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A steel strip guiding rolling structure comprises a support, and a pressure roller and two guide rollers which are parallel and rotatably arranged on the support, wherein the pressure roller and the two guide rollers are arranged in a triangle at the center, and the two guide rollers are tightly attached, and a guide channel for the steel strip to pass through is provided between the two guide rollers.

[0006] Furthermore, an annular groove is formed on the outer circumferential surface of one of the guide rollers, and the guide channel is formed between the annular groove and the outer circumferential surface of the other guide roller.

[0007] Furthermore, the width of the annular groove corresponds to the width of the steel strip, and the depth of the annular groove is 1-1.5 mm greater than the thickness of the steel strip.

[0008] Furthermore, a limiting ring groove corresponding to the guide channel is formed on the outer circumferential surface of the pressure roller, the groove depth of the limiting ring groove is less than the thickness of the steel strip, and the groove width corresponds to the width of the steel strip.

[0009] Furthermore, a gap is respectively left between the pressing roller and the two guide rollers, and the size of the gap is larger than the diameter of the pressing roller.

[0010] Compared with the prior art, the steel strip guide rolling structure described in the utility model has the following advantages:

[0011] The utility model has a simple structure and is easy to operate. When the steel belt is used to bundle the square pipe stack, the steel belt passes around the pressure roller and then goes out from the guide channel between the two guide rollers. The guide channel ensures the linearity of the stretching direction of the steel belt and prevents the steel belt from deflecting. The pressure roller rolls the steel belt to eliminate its bending deformation, so that it is closely attached to the surface of the square pipe stack, the square pipe stack is stably bundled, and the packaging effect of the square pipe stack is improved.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] like Figure 1 As shown, a steel strip guiding rolling structure includes a pressure roller 1, two guide rollers 2 and a bracket 3. The pressure roller 1 is rotatably arranged at one end of the bracket 3, and the two guide rollers 2 are rotatably arranged at the other end of the bracket 3. The pressure roller 1 and the two guide rollers 2 are parallel and the center lines are arranged in a triangular shape. The outer circumferential surfaces of the two guide rollers 2 are tightly attached. At this time, a gap is left between the pressure roller 1 and the two guide rollers 2. Preferably, the size of the gap is larger than the diameter of the pressure roller 1.

[0021] The structure and position relationship of the two guide rollers 2 are as follows: Figure 2 As shown, two guide rollers 2 are arranged with equal diameters, and an annular groove 21 is provided on the outer circumference of one of the guide rollers 2. The width of the annular groove 21 corresponds to the width of the steel strip, and the depth of the annular groove 21 is 1-1.5 mm greater than the thickness of the baling steel strip. A guide channel 22 for guiding the stretching direction of the baling steel strip is formed between the annular groove 21 and the outer circumference of the other guide roller 2.

[0022] The structure of the pressure roller 1 is as follows: Figure 3 As shown, the outer circumference thereof is provided with a limiting ring groove 11, the groove depth of the limiting ring groove 11 is less than the thickness of the steel strip, and the groove width corresponds to the width of the steel strip. After assembly, the limiting ring groove 11 of the pressure roller 1 corresponds to the guide channel 22 of the guide roller 2.

[0023] The working principle of the utility model is as follows Figure 4 As shown, the cut square tube stack 5 is packaged with a steel belt 4 which passes through the limiting ring groove 11 of the pressing roller 1 and then passes through the guide channel 22. After the steel belt 4 is tightened, the device is moved to the position of the square tube stack 5 and the pressing roller 1 and the guide roller 2 located on the outside thereof are closely attached to the surface of the square tube stack 5. An oblique thrust F is applied to the device. The oblique direction of the thrust F ensures that the utility model can move forward, and at the same time enables the pressing roller 1 of the utility model to press the steel belt 4, eliminate the bending deformation of the steel belt 4, and make the steel belt 4 and the surface of the square tube stack 5 closely attached, so as to achieve the stability of the steel belt bundling and packaging.
