Description

TECHNICAL FIELD

[0001] The utility model relates to steel band striping field especially relates to a striping cutting material guiding structure of steel band striping machine. BACKGROUND

[0002] In the production process of steel pipe, the steel band in coil is first unwound, then the wide steel band is cut into multiple thin steel bands by a striping machine, and the thin steel bands are bent and welded into steel pipe. In the process of striping the steel band, the edges of the wide steel band are cut off as edge materials and wound. At present, the edge material just cut off is guided to an edge material winding roller by a vertical guiding roller located behind the striping machine, but the vertical guiding roller cannot effectively support the edge material in the vertical direction. When the moving speed of the edge material is slightly greater than the winding speed of the edge material winding roller, the edge material will gradually move downward without vertical support until it is separated from the vertical guiding roller, so that the vertical guiding roller cannot effectively guide.

[0003] In addition, since the edge of the edge material is relatively sharp, the guiding roller is easily worn out by long-term contact with the edge material, and needs to be replaced regularly. However, the mounting and dismounting steps between the traditional guiding roller and the mounting seat are complicated, and the personnel cannot quickly replace the guiding roller, which affects the production progress. SUMMARY

[0005] To achieve the above-mentioned purpose, the utility model provides a striping cutting material guiding structure of steel band striping machine, which comprises a guiding seat arranged on the striping machine, a sliding strip slidingly connected to the guiding seat, two mounting seat assemblies arranged on the sliding strip, one guiding roller rotatably connected to each mounting seat assembly, and the two guiding rollers arranged in sequence along the conveying direction of the edge material, the front guiding roller arranged horizontally, and the rear guiding roller arranged vertically; the highest point of the front guiding roller is located between the upper end and the lower end of the rear guiding roller.

[0006] As a further improvement of the utility model, each mounting seat assembly comprises a first mounting seat and a second mounting seat, a first bearing arranged in the first mounting seat, and a second bearing arranged in the second mounting seat; the guiding roller is provided with an extension shaft at one end and a fixed shaft at the other end; the extension shaft is insertedly matched with the inner ring of the first bearing at one end, and the fixed shaft is insertedly matched with the inner ring of the second bearing.

[0007] As a further improvement of the utility model, the guiding roller is provided with a guiding hole, the other end of the extension shaft is located in the guiding hole and slidably matched with the guiding hole, a return spring is arranged between the extension shaft and the bottom of the guiding hole; the first mounting seat is provided with a through hole in communication with the inner ring of the first bearing.

[0008] As a further improvement of the utility model, one end of the telescopic shaft is provided with a cover plate, the outside of the guide hole in the guide roller is provided with a clearance slot, the outside of the guide hole opening in the guide roller is provided with a blocking part, and the rear side space of the blocking part is connected with one side of the clearance slot.

[0009] As a further improvement of the utility model, a positioning structure is arranged between the limiting block and the blocking part; the positioning structure comprises a positioning groove and a positioning protrusion which are matched with each other, the positioning groove is arranged on the blocking part, and the positioning protrusion is arranged on the limiting block.

[0010] As a further improvement of the utility model, one end of the telescopic shaft is provided with a polygonal recess.

[0011] Beneficial effects

[0012] Compared with the prior art, the strip cutting and discharging guide structure of the steel strip slitting machine has the following advantages:

[0013] 1. The front guide rollers are arranged horizontally, the rear guide rollers are arranged vertically, the edge material is supported by the horizontal guide rollers to prevent it from sliding downward, and the vertical guide rollers guide the horizontal outward movement of the edge material. This structure can ensure that the edge material does not deviate from the coverage range of the vertical guide rollers, and ensures that the vertical guide rollers always play a guiding role on the edge material.

[0014] 2. The telescopic shaft on the guide roller is inserted and matched with the first bearing of the first mounting seat, the screwdriver or wrench is inserted into the through hole of the first mounting seat and pushes the telescopic shaft, the telescopic shaft is moved out of the inner ring of the first bearing and is retracted into the guide roller, then the fixed shaft is pulled out of the second bearing by moving the guide roller, and the guide roller can be disassembled from the mounting seat assembly, which is convenient to operate.

[0015] 3. When the telescopic shaft is pushed by the screwdriver or wrench, the limiting block on the outside of the telescopic shaft slides along the clearance slot of the guide hole in the guide roller, and then the screwdriver or wrench is rotated, so that the limiting block of the telescopic shaft is rotated to the rear side of the blocking part. The blocking part can prevent the telescopic shaft from resetting outward, and the operation of disassembling or installing the guide roller from the mounting seat assembly is more convenient. When the telescopic shaft needs to be reset, the telescopic shaft is rotated relative to the guide roller by the screwdriver or wrench, so that the limiting block is completely offset from the blocking part, and the limiting block slides along the clearance slot under the action of the reset spring. At this time, the telescopic shaft can be extended outward.

[0016] 4. The positioning structure is arranged between the limiting block and the blocking part, and is specifically a clamping cooperation between the positioning groove and the positioning protrusion. After the positioning protrusion is clamped into the positioning groove, the telescopic shaft and the guide shaft are integrated and can rotate synchronously. Since the pressure of the steel plate edge material on the guide roller is small, the guide roller cannot release the clamping state of the positioning protrusion and the positioning groove when guiding the edge material.

[0017] 5. The polygonal groove at one end of the telescopic shaft is used for cooperation with a wrench or a screwdriver.
