Description

Technical Field

[0001] The present application relates to the technical field of unwinding equipment, and in particular to a material guiding mechanism and an unwinding machine. Background Art

[0002] The uncoiler is a special equipment for the metal sheet leveling line, which is used for placing metal coils and feeding them to the next process. It can be used to form uncoiler, leveling, shearing production lines and other metal sheet processing production lines according to relevant processing requirements. It is suitable for steel, automobile, chemical, metallurgy, rail transportation, engineering machinery, textile machinery, elevators, construction machinery, environmental protection machinery and other industries.

[0003] In simple uncoiler applications, since the two rollers cannot be kept absolutely parallel, the coil will deviate to a certain extent during the rotation process, which may cause damage to the coil and related parts of the uncoiler, affecting the performance and service life of the uncoiler and causing the production line to be unable to operate normally; in addition, if a common material guide structure is set, it is not only easy to collide and damage related parts during loading, but also scratch the coil. This is the current status of the existing technology.

[0004] Therefore, in view of the current status of the above-mentioned prior art, developing a material guiding device and an uncoiler is an issue that needs to be urgently addressed. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present application provides a material guiding mechanism and an uncoiler.

[0006] A material guiding mechanism provided in this application adopts the following technical solution:

[0007] A material guiding mechanism is used on a uncoiler, comprising a first fixed roller, a first squeezing roller, a second fixed roller and a second squeezing roller, wherein the first fixed roller and the second fixed roller are rotatably connected to the uncoiler, and a pressing mechanism is provided on the uncoiler, wherein the first squeezing roller and the second squeezing roller are arranged on the pressing mechanism.

[0008] A further technical solution is that the pressing mechanism includes a guide rod arranged on the uncoiler, a slider slidably arranged on the guide rod, and a spring sleeved on the guide rod, one end of the spring abuts on the slider, and the other end of the spring abuts on the uncoiler; the first squeezing roller and the second squeezing roller are arranged on the slider.

[0009] A further technical solution is that the uncoiler is provided with a first motor for driving the first fixed roller to rotate and a second motor for driving the second fixed roller to rotate, and the first motor and the second motor rotate synchronously in the same direction.

[0010] This application has the following beneficial technical effects:

[0011] By arranging the first fixed roller, the second fixed roller, the first squeezing roller and the second squeezing roller on the uncoiler, the steel coil can be squeezed and fixed after being unfolded to prevent it from deviation and affecting subsequent processing. At the same time, the squeezing effect of the spring can reduce damage to the steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0015] The present application embodiment discloses a material guiding mechanism, which is applied to an unwinding machine. Figure 1 The material guiding mechanism includes a first fixed roller 31, a first squeezing roller 32, a second fixed roller 41 and a second squeezing roller 42. The first fixed roller 31 and the second fixed roller 41 are rotatably connected to the uncoiler. The uncoiler is provided with a pressing mechanism, and the first squeezing roller 32 and the second squeezing roller 42 are arranged on the pressing mechanism.

[0016] Among them, the first fixed roller 31, the first squeezing roller 32, the second fixed roller 41 and the second squeezing roller 42 are all parallel to each other, and the first squeezing roller 32 and the second squeezing roller 42 are respectively rolled and abutted against the first fixed roller 31 and the second fixed roller 41 through a pressing mechanism, which is used to control the metal coil to remain flat after unwinding.

[0017] Specifically, the pressing mechanism includes a guide rod 51 arranged on the uncoiler, a slider 53 slidably arranged on the guide rod 51, and a spring 52 sleeved on the guide rod 51, one end of the spring 52 abuts on the slider 53, and the other end of the spring 52 abuts on the uncoiler; the first squeezing roller 32 and the second squeezing roller 42 are arranged on the slider 53.

[0018] After the steel coil is unrolled, it passes between the first squeezing roller 32 and the first fixed roller 31, and between the second squeezing roller 42 and the second fixed roller 41. The spring 52 pushes the slider 53 to move downward, thereby driving the first squeezing roller 32 and the second squeezing roller 42 set on the slider 53 to roll and press against the unrolled steel coil. In this way, the steel coil can be squeezed and fixed after unrolling to prevent it from running off and affecting subsequent processing. At the same time, the squeezing effect of the spring 52 can reduce damage to the steel plate.

[0019] Furthermore, the uncoiler is provided with a first motor 61 for driving the first fixed roller 31 to rotate and a second motor 62 for driving the second fixed roller 41 to rotate, and the first motor 61 and the second motor 62 rotate synchronously in the same direction. The first motor 61 and the second motor 62 drive the steel plate to unfold and move, and can actively pull the steel coil to rotate, so that the steel coil and the unfolded part are in a tight state, preventing the steel plate from sagging and causing wrinkles or deviation.

[0020] The embodiment of the present application further discloses an uncoiler, comprising a frame 1, an uncoiler roller 2 arranged on the frame 1 and the aforementioned material guiding mechanism.

[0021] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
