Description

Technical Field

[0001] The utility model relates to the technical field of decoilers, and more specifically, to an automatic shearing device for the packing belt of a decoiler. Background Art

[0002] Strip steel is a narrow and long steel plate produced by various rolling enterprises to meet the needs of different industrial departments for industrial production of various metal or mechanical products. Its width is generally between 20 mm and 200 mm, and its length varies slightly according to the size of each coil. The strip steel has a thin thickness, a narrow width, a long length, and is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving.

[0003] At present, during the process of uncoiling the strip steel for transverse processing, the removal of the packing belt is carried out by manual shearing operation. The entire operation process requires workers to enter between the front side of the decoiler and the guide plate table. Once the equipment is accidentally started, the lifting of the guide plate will pose a great safety hazard to the staff. In view of this, we propose an automatic shearing device for the packing belt of a decoiler. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide an automatic shearing device for the packing belt of a decoiler, so as to solve the technical problem that the removal of the current traditional packing belt is carried out by manual shearing operation, and once the equipment is accidentally started, it is easy to pose a safety hazard to the staff.

[0005] To solve the above technical problems, the utility model provides the following technical solution: an automatic shearing device for the packing belt of a decoiler, including a support frame with a centering seat detachably installed inside;

[0006] A strip steel coil is detachably arranged outside the centering seat;

[0007] A pressing arm assembly for movably abutting against the strip steel coil to achieve positioning is rotatably arranged on one side of the support frame;

[0008] The pressing arm assembly includes a support structure with a positioning assembly arranged inside;

[0009] The positioning assembly includes a motor fixedly arranged on the support structure. The motor is connected by a motor shaft to a rotating shaft rotatably installed inside the support structure, and a telescopic assembly is arranged on the outer edge surface of the rotating shaft;

[0010] The telescopic assembly includes a turntable fixedly arranged on the outer edge surface of the rotating shaft. A plurality of arc-shaped chutes are annularly arranged inside the turntable, and disc body assemblies fixedly connected to the support structure are arranged on both sides of the turntable;

[0011] The disk assembly includes a fixed disk with a plurality of limiting slots arranged in an annular array inside. A tool rest structure for cutting the packaging bag on the surface of the strip coil is movably installed in the limiting slots, and one end of the tool rest structure is inserted into the arc-shaped slideway.

[0012] In the utility model, by designing a motor, a rotating shaft and a turntable, the motor can be started to make the rotating shaft rotate, thereby driving the turntable to rotate. Also, because one end of the tool rest structure is inserted into the arc-shaped slideway, during the rotation of the turntable, a force is applied to one end of the tool rest structure through the arc-shaped structure of the arc-shaped slideway, thereby forcing the tool rest structure to linearly extend or retract in the limiting slot. In the extended state of the tool rest structure, it can cut the packaging bag on the surface of the strip coil, eliminating the need for manual shearing and thus avoiding potential safety hazards to workers caused by accidental startup of the equipment. When the tool rest structure is in the retracted state, the telescopic assembly abuts against the surface of the strip coil, achieving the effect of abutting and positioning during the uncoiling process of the strip coil.

[0013] Preferably, the tool rest structure includes a tool holder movably installed in the limiting slot. A straight blade is centrally configured at one end of the tool holder, and a plurality of inclined blades are evenly arranged on both sides of the straight blade at one end of the tool holder. V-shaped cutting angles are formed between the inclined blades on both sides of the straight blade and the straight blade. Both the straight blade and the inclined blades are triangular structures, and arc-shaped cutting edges are formed on both sides of the straight blade and the inclined blades.

[0014] Preferably, a positioning rod is configured at one end of the tool holder. The end of the positioning rod away from the tool holder is movably inserted into the arc-shaped slideway.

[0015] Preferably, the support structure includes a sleeve with support plates symmetrically configured on the outer edge surface. A connecting rod is fixedly connected between the support plates. Bearings are arranged at both ends of the outer edge surface of the rotating shaft, and positioning wheels are arranged on the outer edge surfaces of the bearings.

[0016] Preferably, a fixed frame fixedly sleeved on the outer edge surface of the rotating shaft is arranged inside the turntable. A positioning frame rotatably sleeved on the outer edge surface of the rotating shaft is fixedly arranged inside the fixed disk, and a connecting plate is configured on the outer edge surface of the fixed disk. One end of the connecting plate away from the fixed disk is connected with a fixed ring fixedly sleeved on the outer edge surface of the connecting rod.

[0017] Preferably, side plates are symmetrically configured on one side of the support frame, and a pneumatic telescopic rod is detachably installed inside the support frame. A connecting shaft is rotatably installed inside the side plates. A rocker arm is fixedly installed on the outer edge surface of the connecting shaft. A movable rod is arranged inside the pneumatic telescopic rod. A connecting seat is configured at one end of the movable rod. The connecting seat is rotatably connected with one end of the rocker arm. The sleeve is fixedly sleeved on one end of the outer edge surface of the connecting shaft.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. By designing a motor, a rotating shaft and a turntable, the present utility model can start the motor to rotate the rotating shaft, thereby driving the turntable to rotate. Since one end of the tool rest structure is inserted into the arc-shaped slideway, during the rotation of the turntable, the arc-shaped structure of the arc-shaped slideway exerts a force on one end of the tool rest structure, thereby forcing the tool rest structure to linearly extend or retract in the limit groove. In the extended state of the tool rest structure, it can cut the packaging bag on the surface of the steel strip coil, eliminating the need for manual shearing, thus avoiding potential safety hazards to workers caused by accidental equipment startup. When the tool rest structure is in the retracted state, the telescopic assembly abuts against the surface of the steel strip coil, achieving an abutting and positioning effect during the uncoiling process of the steel strip coil, solving the problem that the removal of traditional packaging belts relies on manual shearing operations, and once the equipment starts accidentally, it is likely to pose a safety hazard to workers.

[0020] 2. The present utility model also designs a straight blade and an inclined blade, and forms a V-shaped cutting angle between the inclined blades on both sides of the straight blade and the straight blade. When cutting the packaging belt, the inclined blades on both sides of the straight blade can form an inclined cutting angle, which is conducive to smoothly cutting the packaging belt. At the same time, both the straight blade and the inclined blade are triangular structures, and the two sides of the straight blade and the inclined blade form an arc-shaped cutting edge. The triangular tool has the effect of enhancing the structural strength when cutting the packaging bag, and the arc-shaped cutting edge can simulate the effect of manual sliding cutting during the contact and rotation of the packaging belt, thus further ensuring the smooth cutting of the packaging belt.

[0030] In an embodiment of the present utility model, as Figure 5 and Figure 6 shown, the tool holder structure includes a tool holder 906 movably installed in the limiting groove. A straight blade 908 is centrally configured at one end of the tool holder 906. And a plurality of oblique blades 909 are equidistantly arranged on both sides of the straight blade 908 at one end of the tool holder 906. A V-shaped cutting angle is formed between the oblique blades 909 on both sides of the straight blade 908 and the straight blade 908. Both the straight blade 908 and the oblique blade 909 are in a triangular structure. And arc-shaped cutting edges are formed on both sides of the straight blade 908 and the oblique blade 909. A positioning rod 907 is configured at one side end of the tool holder 906. One end of the positioning rod 907 away from the tool holder 906 is movably inserted into the arc-shaped slideway 903.

[0031] In an embodiment of the present utility model, as Figures 2-5As shown in the figure, the support structure includes a sleeve 703 symmetrically configured with support plates 701 on its outer edge surface. A connecting rod 702 is fixedly connected between the support plates 701. Both ends of the outer edge surface of the rotating shaft 802 are provided with bearings 704.

[0033] Working principle: This embodiment provides an automatic shearing device for the packing belt of an uncoiler. When in use, first, the strip steel coil 11 is placed on the centering seat 10. By starting the pneumatic telescopic rod 4, the movable rod inside it can extend, thereby pushing the rocker arm 6 to deflect, causing the connecting shaft 3 to rotate. The connecting shaft 3 drives the pressing arm assembly 7 to deflect, so that the positioning wheel 803 abuts against the surface of the strip steel coil 11. When it is necessary to cut the packing belt on the strip steel coil 11, the motor 801 can be started to make the rotating shaft 802 rotate, thereby driving the turntable 901 to rotate. Also, since one end of the tool rest structure is inserted into the arc-shaped slideway 903, during the rotation of the turntable 901, a force is applied to one end of the tool rest structure through the arc-shaped structure of the arc-shaped slideway 903, forcing the tool rest structure to extend linearly in the limit slot, so that the ends of the straight blade 908 and the inclined blade 909 abut against the surface of the strip steel coil 11. The centering seat 10 can drive the strip steel coil 11 to rotate. When the packing belt on the surface of the strip steel coil 11 rotates to contact the straight blade 908 and the inclined blade 909, the packing belt is cut by the straight blade 908 and the inclined blade 909. Moreover, a V-shaped cutting angle is designed between the inclined blades 909 on both sides of the straight blade 908 and the straight blade 908. When cutting the packing belt, the inclined blades 909 on both sides of the straight blade 908 can form an inclined cutting angle, which is conducive to smoothly cutting the packing belt. At the same time, both the straight blade 908 and the inclined blade 909 are triangular structures, and the two sides of the straight blade 908 and the inclined blade 909 form arc-shaped cutting edges. The triangular tool has the effect of enhancing the structural strength when cutting the packaging bag, and the arc-shaped cutting edge can simulate the effect of manual sliding cutting during the contact and rotation of the packing belt.
