[0002] Steel coil slitting is a process that divides wide metal coils into narrow strips of different sizes according to customer needs after the steel coils are produced. In the slitting process, a steel coil slitting machine is generally used to cut the steel coils.

[0003] When the existing steel coil slitting machine is in use, washers and slitting blades are usually sleeved on the outer surface of the rotating shaft, and the spacing between the slitting blades is adjusted by the width of the washers. When the spacing of the slitting blades needs to be changed, multiple sets of washers and slitting blades need to be removed, which is cumbersome to operate and increases downtime. Utility Model Content

When the spacing of the slitting blades needs to be changed, it is necessary to remove multiple sets of gaskets and slitting blades, which is cumbersome to operate and increases the downtime.

[0005] In order to solve the above technical problems, the utility model provides an adjustable stripping device for facilitating strip cutting, comprising:

[0006] A striping assembly, the striping assembly comprising a support frame;

[0007] An adjustment component, the adjustment component includes a support rod connected to the outer side of the upper end of the support frame, a sliding groove opened at the central position of the outer side of the support rod, a sliding sleeve sleeved on the outer surface of the support rod, a through hole opened on one side of the outer surface of the sliding sleeve, a fixing column placed inside the through hole, a hollow annular groove opened on the other side of the outer surface of the sliding sleeve, a swivel ring sleeved on the inner position of the hollow annular groove and a positioning rod connected to the outer surface of the swivel ring.

[0008] Furthermore, the slitting assembly also includes a driving motor, a rotating shaft and a slitting blade;

[0009] The driving motor is connected to the outer end of one side of the support frame, the rotating shaft is sleeved on the upper end of the inner part of the support frame, and the slitting blade is sleeved on the outer surface of the rotating shaft.

[0010] Furthermore, the slide groove and the through hole are opened relative to the fixing column, and the fixing column passes through the through hole and extends outward.

[0011] Furthermore, the outer surface of the fixing column is connected to the fixing nut, and the outer surface of the fixing column has a threaded structure opened relative to the fixing nut.

[0012] Furthermore, the outer end surface of the positioning rod is flush with the outer end surface of the sliding sleeve, and the support rod is located below the outer side of the slitting blade.

[0013] Furthermore, it also includes a protection component, which includes an electric telescopic rod connected to the outer position of the top end of the support frame, a movable plate connected to the bottom end of the electric telescopic rod, a pressure sensor connected to both sides of the lower end of the movable plate, a telescopic spring connected to the bottom end of the pressure sensor, a movable block connected to the bottom end of the telescopic spring, a fixed shaft sleeved on the inner position of the movable block, and a driven roller sleeved on the outer surface of the fixed shaft.

[0014] Furthermore, the electric telescopic rod passes through the upper end of the support frame and extends downward, and the movable plate is located at the upper end of the support frame.

[0015] Furthermore, the movable plate is an inverted U-shaped structure, and the driven rollers are located on both sides of the slitting blades.

[0016] Compared with the prior art, the utility model has the following beneficial effects: by setting the adjustment component, when the spacing of the slitting blades needs to be adjusted, the fixing column is moved outward so that the fixing column does not fix the sliding sleeve, and then the sliding sleeve is slid on the outer surface of the support rod, so that the sliding sleeve drives the positioning rod to move through the rotating ring, and the spacing between the two groups of positioning rods is measured to confirm the spacing of the slitting blades. When the confirmation is completed, the sliding sleeve is fixed by the fixing column, and then the positioning rod is rotated so that the outer end of the positioning rod contacts the outer surface of the rotating shaft, so that the slitting blades are accurately positioned, the operation is simple, and time is saved;

[0017] At the same time, by arranging a protective component, when the slitting blade is slitting the steel coil, the electric telescopic rod is controlled to extend downward, so that the electric telescopic rod drives the movable plate to move downward, and the movable plate drives the fixed shaft and the driven roller to move downward. When the driven roller moves to contact the outer surface of the steel coil, the movable plate is located at the outer position of the upper end of the slitting blade, which can prevent the operator from accidentally touching the slitting blade and increase the safety of the operator. In addition, under the reaction effect exerted by the steel coil on the driven roller, the driven roller can drive the telescopic spring to be compressed through the fixed shaft and the movable block, so that the pressure sensor measures the elastic force of the telescopic spring, thereby measuring the tension of the steel coil, thereby ensuring the accuracy of the slitting process.

[0032] The slitting assembly also includes a driving motor 12, a rotating shaft 13 and a slitting blade 14;

[0033] The driving motor 12 is connected to the outer end of one side of the support frame 11, the rotating shaft 13 is sleeved on the upper end of the inner part of the support frame 11, and the slitting blade 14 is sleeved on the outer surface of the rotating shaft 13;

[0045] The electric telescopic rod 31 penetrates the upper end of the support frame 11 and extends downward, and the movable plate 32 is located at the upper end of the support frame 11;
