Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil processing, and in particular relates to an adjustable steel coil uncoiler. Background Art

[0002] Steel coil, also known as coiled steel. Steel is hot-pressed or cold-pressed into coils. In order to facilitate storage and transportation, and to facilitate various processing (such as processing into steel plates, steel strips, etc.), the formed coils are mainly hot-rolled coils and cold-rolled coils. Hot-rolled coils are processed products before the recrystallization of steel billets. Cold-rolled coils are the subsequent processing of hot-rolled coils. Uncoilers are special equipment for leveling metal plates. They are used to level steel plates and uneven plates. According to the relevant configuration, uncoiling, leveling, shearing production lines and other plate product production lines can be formed. They are widely used in machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries.

[0003] After searching CN219151191U, a steel coil uncoiler with an adjusting device is disclosed. By pressing the adjusting plate, the steel coils of different sizes can be installed for processing by adjusting the adjusting plate, so that the use range of the equipment is wider and will not be restricted. One side of the connecting rod is connected to the motor, the outer wall of the connecting rod is movably connected to the limit hole one and the limit hole three, and the other side of the connecting rod is movably connected to the adjusting plate. The direct connection between the motor and the connecting rod makes the whole device highly automated, which greatly reduces the labor intensity of workers.

[0004] When the clamping roller in the uncoiler is clamping steel coils of different specifications and sizes, it is necessary to adjust the bolts so as to drive the clamping roller to be tightly attached to the outer wall of the steel coil. Such adjustment is rather cumbersome and inconvenient for the staff to operate.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to solve the above technical problem that when the pressing roller in the uncoiler is pressed against steel coils of different specifications and sizes, it is necessary to adjust the bolts so as to drive the pressing roller to be close to the outer wall of the steel coil, and such adjustment is cumbersome and inconvenient for the staff to operate, the basic concept of the technical solution adopted by the utility model is:

[0007] An adjustable steel coil uncoiler comprises a machine base;

[0008] A reel is arranged on one side of the base, an automatic adjustment clamping mechanism is arranged on the top of the base, a limit mechanism is arranged above the automatic adjustment clamping mechanism, and the automatic adjustment clamping mechanism includes a motor fixedly connected to the top of the base:

[0009] The top of the sliding panel also is provided with an angular channel, and the top of the sliding panel is provided with a channel that is cooperatively connected with the first sliding panel, and the channel is connected with the second sliding panel to form a circle.

[0010] As a preferred embodiment of the utility model, the limiting mechanism includes a support block fixedly connected to the top of the support plate, a sliding hole is opened on the outer wall of the support block, a spring is fixedly connected to the inner wall of the sliding hole, an end of the spring away from the sliding hole is fixedly connected to a positioning rod, the outer wall of the positioning rod is slidably connected to the inner wall of the sliding hole, and a lever is fixedly connected to the top of the outer wall of the positioning rod.

[0011] As a preferred embodiment of the present utility model, the number of the second rotating shaft and the force-bearing plate are both two, the second rotating shaft and the force-bearing plate are distributed on the left and right sides of the connecting rotating rod in a left-right symmetrical structure, and the material of the force-bearing plate is iron material.

[0012] As a preferred embodiment of the present invention, the length of the rotating push rod exceeds the length of the force-bearing plate when it rotates to a vertical state below.

[0013] As a preferred implementation of the utility model, the inner wall of the sliding groove provided on the outer wall of the fixing block fits closely with the outer wall of the sliding block.

[0014] As a preferred embodiment of the utility model, the outer wall of the positioning rod fits closely with the inner wall of the positioning hole formed in the outer wall of the connecting rotating rod, and when the positioning hole moves to a position corresponding to the positioning rod, the connecting rotating rod is in a vertical state.

[0015] As a preferred embodiment of the utility model, a through-slide groove is provided on the top of the support block, and the outer wall of the shifting rod is slidably connected to the inner wall of the through-slide groove and fits closely with the inner wall of the through-slide groove.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model, the force-bearing plate is pushed to rotate downward through the rotation of the second rotating shaft and fit with the outer wall of the connecting rotating rod, and the magnetic attraction with the magnet is separated. Then the motor is started, and its output end will drive the rotating rod to rotate. When the rotating rod rotates, it can drive the rotating push rod to rotate clockwise, so as to contact and squeeze and push the force-bearing plate on the left side, so as to drive the connecting rotating rod to rotate counterclockwise through the first rotating shaft, so as to drive the fixed block and the clamping roller to rotate, so as to separate from the top of the reel, and then insert the steel coil into the reel, and then rotate the rotating rod counterclockwise to drive the rotating push rod to rotate, so as to squeeze and push the force-bearing plate on the right side. The force plate drives the connecting rotating rod to rotate clockwise, which can drive the fixed block and the pressure roller to move to the top of the steel coil. At the same time, during the rotation of the pressure roller, it will contact and be squeezed by the top of the steel coil, driving the slider to move upward on the outer wall of the slide rod, and at the same time, the strong compression spring is squeezed and compressed. Subsequently, the strong compression spring is used to rebound and push the pressure roller in the opposite direction to squeeze the top of the steel coil to squeeze and compact the steel coil. As the diameter of the steel coil decreases during the unwinding process, the pressure roller is always pushed to be pressed against the top of the steel coil through the rebound of the strong compression spring. There is no need to manually adjust the position of the pressure roller, and it can adapt to steel coils of different specifications.

[0018] According to the utility model, before the connecting rotating rod needs to be rotated, the lever is first moved backward, so that the movement of the lever will drive the positioning rod to move backward, and at the same time, the positioning rod will squeeze and compress the spring during the movement until the outer wall of one end of the positioning rod is separated from the inner wall of the positioning hole opened on the outer wall of the connecting rotating rod, so that the positioning effect on the connecting rotating rod can be released, thereby adjusting the position of the clamping roller to facilitate the loading of the steel coil.

[0029] Furthermore, there are two second rotating shafts 3112 and two force plates 3113, which are symmetrically distributed on the left and right sides of the connecting rotating rod 315, and the force plates 3113 are made of iron. In this way, the rotating push rod 313 can be controlled to rotate forward and reverse, and then the connecting rotating rod 315 can be controlled to rotate forward and reverse, thereby controlling the clamping roller 3110 to move, which is convenient for loading the steel coil.

[0030] Furthermore, the length of the rotating push rod 313 exceeds the length of the force-bearing plate 3113 when it is rotated to the vertical state below, so that when the rotating push rod 313 rotates, it will contact and squeeze the force-bearing plate 3113.

[0031] Furthermore, the inner wall of the slide groove opened on the outer wall of the fixed block 316 fits snugly with the outer wall of the slider 318, thereby ensuring the tightness between the outer wall of the slider 318 and the inner wall of the slide groove, thereby ensuring the stability of the clamping roller 3110 during the clamping operation.

[0034] Furthermore, a through-slide groove is provided at the top of the support block 321, and the outer wall of the lever 323 is slidably connected to the inner wall of the through-slide groove and fits closely with the inner wall of the through-slide groove, so that the lever 323 can be moved left and right on the inner wall of the through-slide groove by the through-slide groove.

[0035] The working principle of an adjustable steel coil uncoiler in this embodiment is as follows: first, place the steel coil on the reel 2, push the force plate 3113 downward through the rotation of the second rotating shaft 3112 to fit the outer wall of the connecting rotating rod 315, and separate the magnetic attraction from the magnet 3111, then start the motor 311, and its output end will drive the rotating rod 312 to rotate. When the rotating rod 312 rotates, it can drive the rotating push rod 313 to rotate clockwise, so that it can contact and squeeze and push the force plate 3113 on the left side, so that it can drive the connecting rotating rod 315 to rotate counterclockwise through the first rotating shaft 314, so that the fixing block 316 and the pressing roller 3110 can be driven to rotate, thereby separating from the top of the reel 2, and then the steel coil is inserted into the reel 2, and then the rotating rod 312 is rotated counterclockwise to drive the rotating push rod 3 13 is rotated, thereby squeezing and pushing the force-bearing plate 3113 on the right side to drive the connecting rotating rod 315 to rotate clockwise, so that the fixed block 316 and the clamping roller 3110 can be driven to move to the top of the steel coil. At the same time, during the rotation of the clamping roller 3110, it will contact and be squeezed by the top of the steel coil, driving the slider 318 to move upward on the outer wall of the slide rod 317, and at the same time, the strong compression spring 319 is squeezed and compressed, and then the strong compression spring 319 is used to rebound and push the clamping roller 3110 to squeeze the top of the steel coil in the opposite direction to squeeze and press the steel coil. As the diameter of the steel coil decreases during the unwinding process, the clamping roller 3110 is always pushed to be pressed on the top of the steel coil through the rebound of the strong compression spring 319, so there is no need to manually adjust the position of the clamping roller 3110, and it can adapt to steel coils of different specifications.

[0036] Before the connecting rod 315 needs to be rotated, the lever 323 is first moved backward, so that the movement of the lever 323 will drive the positioning rod 324 to move backward. At the same time, the positioning rod 324 will squeeze and compress the spring 322 during the movement until the outer wall of one end of the positioning rod 324 is separated from the inner wall of the positioning hole opened on the outer wall of the connecting rod 315. In this way, the positioning effect of the connecting rod 315 can be released, so that the position of the clamping roller 3110 can be adjusted to facilitate the loading of the steel coil.
