Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, and in particular to a double cone uncoiler. Background Technology

[0002] Steel strip is a narrow and long steel plate, with a width of less than 1300mm. It is relatively thin, narrow, and long, and is generally supplied in coils. According to the processing method, it can be divided into hot-rolled steel strip and cold-rolled steel strip. According to the quality of the steel, it can be divided into high-quality steel strip and ordinary steel strip. Steel strip can be made from steel grades such as plain carbon steel, carbon structural steel, spring steel, and stainless steel. It is widely used in the manufacture of welded pipes, clamps, washers, spring sheets, saw blades, and blades. It has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving.

[0003] However, the lack of a guardrail after the steel strip is clamped in the double cone uncoiler causes it to deviate. This is because the lack of a guardrail provides insufficient lateral constraint on the steel strip, making it difficult to limit its deviation. As a result, the steel strip is easily affected by external forces, uneven tension, and irregularity of the steel coil itself during the uncoiling or rewinding process, which can cause it to deviate from the normal operating trajectory. Deviation will reduce the accuracy of subsequent processing, such as cutting size deviation and welding position misalignment, which will affect product quality and increase the scrap rate. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing double-cone uncoiler for steel strip processing that causes deviation due to the lack of a guard after clamping the steel strip. The reason is that the lack of a guard provides insufficient lateral constraint on the steel strip, making it difficult to limit its deviation. As a result, the steel strip is easily affected by external forces, uneven tension, and irregularity of the steel coil itself during uncoiling or rewinding, which can lead to a decrease in the accuracy of subsequent processing, such as deviation in cutting dimensions and misalignment of welding positions, affecting product quality and increasing the scrap rate. Therefore, a double-cone uncoiler is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a double-cone uncoiler, comprising a machine body and a protective device. A base is fixedly connected to the lower surface of the machine body, and a cone head is installed at the drive end of the machine body. The protective device is disposed on the surface of the cone head and includes a strip groove. The strip groove is formed in the inner wall of the cone head, and a slide rod is slidably connected to the inner wall of the strip groove. An adjustment groove is formed on the surface of the slide rod. A rocker arm is fixedly connected to the surface of the cone head, and a rotating rod is rotatably connected to the surface of the rocker arm. The rotating rod engages with the adjustment groove on the surface of the slide rod. An arc-shaped plate is fixedly connected to the upper surface of the slide rod. By setting the protective device, the adjustable arc-shaped plate blocks the steel strip and can flexibly adjust its position according to the thickness of the steel strip. After the steel strip is clamped by the cone head, the arc-shaped plate provides lateral constraint, effectively reducing the deviation problem caused by the lack of a barrier, ensuring the stable operation of the steel strip during uncoiling or rewinding, thereby improving processing accuracy and product quality, and reducing the scrap rate.

[0006] Preferably, a torsion spring is fitted onto the surface of the rocker arm. The two ends of the torsion spring are fixedly connected to the rotating rod and the cone head, respectively. By setting the torsion spring, the torsion spring mainly provides elastic force and achieves fixation. When the sliding rod is pulled to adjust the arc plate to a suitable position, the rotating rod is released, and the torsion spring loses its restraint and releases its elastic force, squeezing and pushing the rotating rod into the adjustment groove, so that the rotating rod and the adjustment groove are tightly abutted, thereby fixing the position of the arc plate and ensuring that the arc plate remains stable during the process of blocking the steel belt to prevent deviation.

[0007] Preferably, a pressure spring is fixedly connected to the lower surface of the slide rod, and the end of the pressure spring away from the slide rod is fixedly connected to the cone head.

[0008] Preferably, there are four arc-shaped plates arranged in a circumferential array along the cone head. By setting the arc-shaped plates, when using the double cone uncoiler, the machine body drives the cone head to clamp the steel strip. After adjusting the position of the arc-shaped plates according to the thickness of the steel strip, making them slightly larger than the diameter of the steel strip and fixing them, the arc-shaped plates can provide lateral constraint on the steel strip during the uncoiling or rewinding process, limiting its deviation.

[0009] Preferably, the surface of the cone head is provided with a linkage component, which includes a round rod that is slidably connected to the cone head. A connecting rod is fixedly connected to the surface of the round rod. By setting the linkage component, a convenient operation method is provided for the readjustment of the arc plate position. Pulling the pull rod can quickly release the fixing between the rotating rod and the adjustment groove. The position of the arc plate can be readjusted without cumbersome operation, saving adjustment time, improving work efficiency, and allowing the equipment to complete the adaptation adjustment more quickly when dealing with steel strips of different specifications.

[0010] Preferably, a rope is fixedly connected to the surface of the connecting rod, and the end of the rope away from the connecting rod is fixedly connected to the rotating rod. By setting the rope, the rotating rod is pulled, and the position of the arc plate can be quickly released and adjusted. When the pull rod is pulled, the pull rod drives the round rod to move, and the round rod drives the connecting rod and the rope. The rope pulls the rotating rod to disengage it from the adjustment groove. In this way, the position of the arc plate can be easily adjusted again to adapt to the processing requirements of steel strips of different thicknesses, thereby better playing the role of the arc plate in blocking the steel strip and reducing deviation.

[0011] Preferably, a pull rod is fixedly connected to the surface of the round rod, and the round rod and the pull rod are arranged in a "T" shape.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up a protective device, during use, the machine body drives the cone head to clamp the steel strip in the middle of the cone head. Then, according to the thickness of the steel strip, the sliding rod is pulled to move the arc plate until the arc plate is slightly larger than the diameter of the steel strip. Then, the rotating rod is released, and the torsion spring loses its restraint and generates elastic force to squeeze the rotating rod against the adjusting groove to complete the fixation. The arc plate blocks the steel strip, reducing the possibility of the steel strip running off-center. By setting up a protective device, the adjustable arc plate blocks the steel strip and can flexibly adjust its position according to the thickness of the steel strip. After the steel strip is clamped by the cone head, the arc plate provides lateral restraint, effectively reducing the problem of running off-center due to lack of a barrier, ensuring the stable operation of the steel strip during uncoiling or rewinding, thereby improving processing accuracy and product quality, and reducing the scrap rate.

[0014] In this invention, by setting up a linkage component, when the position of the arc plate needs to be readjusted, pulling the pull rod causes the round rod to move, and at the same time, the round rod drives the connecting rod and the rope. The rope pulls the rotating rod to disengage from the adjustment groove, at which point the position of the arc plate can be readjusted again, facilitating quick release of the fixation. By setting up the linkage component, a convenient operation method is provided for the readjustment of the arc plate position. Pulling the pull rod can quickly release the fixation between the rotating rod and the adjustment groove, achieving readjustment of the arc plate position without cumbersome operations, saving adjustment time, improving work efficiency, and allowing the equipment to more quickly adapt and adjust to different specifications of steel strips.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a double cone uncoiling machine, including a machine body 1 and a protective device 3. A base 4 is fixedly connected to the lower surface of the machine body 1, a cone 2 is installed at the drive end of the machine body 1, and the protective device 3 is disposed on the surface of the cone 2.

[0022] In this embodiment: the protective device 3 includes a strip groove 33, which is formed in the inner wall of the cone head 2. A sliding rod 32 is slidably connected to the inner wall of the strip groove 33. An adjustment groove is formed on the surface of the sliding rod 32. A rocker arm 36 is fixedly connected to the surface of the cone head 2. A rotating rod 35 is rotatably connected to the surface of the rocker arm 36. The rotating rod 35 engages with the adjustment groove on the surface of the sliding rod 32. An arc plate 31 is fixedly connected to the upper surface of the sliding rod 32. By setting the protective device 3, the adjustable arc plate 31 blocks the steel strip and can flexibly adjust its position according to the thickness of the steel strip. After the steel strip is clamped by the cone head 2, the arc plate 31 provides lateral constraint, effectively reducing the deviation problem caused by the lack of a barrier, ensuring the stable operation of the steel strip during uncoiling or rewinding, thereby improving processing accuracy and product quality and reducing the scrap rate.

[0023] Specifically, a torsion spring 38 is fitted onto the surface of the rocker arm 36. The two ends of the torsion spring 38 are fixedly connected to the rotating rod 35 and the cone head 2, respectively. By setting the torsion spring 38, the main function of the torsion spring 38 is to provide elastic force and achieve fixation. When the sliding rod 32 is pulled to adjust the arc plate 31 to a suitable position, the rotating rod 35 is released, and the torsion spring 38 loses its restraint and releases its elastic force, squeezing and pushing the rotating rod 35 into the adjustment groove, so that the rotating rod 35 and the adjustment groove are tightly pressed together, thereby fixing the position of the arc plate 31 and ensuring that the arc plate 31 remains stable during the process of blocking the steel belt to prevent deviation.

[0024] Specifically, a pressure spring 34 is fixedly connected to the lower surface of the slide bar 32, and the end of the pressure spring 34 away from the slide bar 32 is fixedly connected to the cone head 2.

[0025] Specifically, there are four arc-shaped plates 31, which are arranged in a circumferential array along the cone head 2. By setting the arc-shaped plates 31, when using the double cone uncoiler, the machine body 1 drives the cone head 2 to clamp the steel strip. The position of the arc-shaped plates 31 is adjusted according to the thickness of the steel strip so that it is slightly larger than the diameter of the steel strip and then fixed. The arc-shaped plates 31 can provide lateral constraint on the steel strip during the uncoiling or rewinding process, limiting its deviation.

[0026] Specifically, the surface of the cone head 2 is provided with a linkage component 37, which includes a round rod 372. The round rod 372 is slidably connected to the cone head 2, and a connecting rod 373 is fixedly connected to the surface of the round rod 372.

[0027] In this embodiment, by setting the linkage component 37, a convenient operation method is provided for the readjustment of the position of the arc plate 31. Pulling the pull rod 371 can quickly release the fixing of the rotating rod 35 and the adjustment groove. The position of the arc plate 31 can be readjusted without cumbersome operation, saving adjustment time, improving work efficiency, and allowing the equipment to complete the adaptation adjustment more quickly when dealing with steel strips of different specifications.

[0028] Specifically, a rope 374 is fixedly connected to the surface of the connecting rod 373, and the end of the rope 374 away from the connecting rod 373 is fixedly connected to the rotating rod 35.

[0029] In this embodiment: by setting up a rope 374 to pull the rotating rod 35, the position of the arc plate 31 can be quickly released from fixation and adjusted. When the pull rod 371 is pulled, the pull rod 371 drives the round rod 372 to move, and the round rod 372 drives the connecting rod 373 and the rope 374. The rope 374 pulls the rotating rod 35 to disengage it from the adjustment groove. In this way, the position of the arc plate 31 can be easily adjusted again to adapt to the processing requirements of steel strips of different thicknesses, thereby better utilizing the function of the arc plate 31 to block the steel strip and reduce deviation.

[0030] Specifically, a pull rod 371 is fixedly connected to the surface of the round rod 372, and the round rod 372 and the pull rod 371 are arranged in a "T" shape.

[0031] Working principle: By setting up the protective device 3, during use, the machine body 1 drives the cone head 2 to clamp the steel strip in the middle of the cone head 2. Then, according to the thickness of the steel strip, the sliding rod 32 is pulled to move the arc plate 31 until the arc plate 31 is slightly larger than the diameter of the steel strip. Then, the rotating rod 35 is released, and the torsion spring 38 loses its restraint and generates elastic force to squeeze the rotating rod 35 against the adjusting groove to complete the fixation. The arc plate 31 blocks the steel strip, reducing the deviation of the steel strip. By setting up the protective device 3, the adjustable arc plate 31 blocks the steel strip and can flexibly adjust its position according to the thickness of the steel strip. After the steel strip is clamped by the cone head 2, the arc plate 31 provides lateral restraint, effectively reducing the deviation problem caused by the lack of a barrier, ensuring the stable operation of the steel strip during uncoiling or rewinding, thereby improving processing accuracy and product quality, and reducing the scrap rate.

[0032] By setting up the linkage component 37, when the position of the arc plate 31 needs to be readjusted, the pull rod 371 is pulled, which drives the round rod 372 to move. At the same time, the round rod 372 drives the connecting rod 373 and the rope 374. The rope 374 pulls the rotating rod 35 to disengage from the adjustment groove. At this time, the position of the arc plate 31 can be readjusted again, which is convenient for quick release of the fixation. By setting up the linkage component 37, a convenient operation method is provided for the readjustment of the position of the arc plate 31. Pulling the pull rod 371 can quickly release the fixation of the rotating rod 35 and the adjustment groove. The position of the arc plate 31 can be readjusted without cumbersome operation, saving adjustment time, improving work efficiency, and allowing the equipment to complete the adaptation adjustment more quickly when dealing with steel strips of different specifications.
