Description

Technical Field

[0001] The utility model relates to the technical field of metal coil processing equipment, in particular to a stripping rack with improved structure. Background Art

[0002] During the processing of metal coils, such as cross-cutting (cutting continuous metal sheets into metal plate parts) or slitting, the metal coil needs to be placed on an uncoiler, and the head of the metal coil is pulled into a flattening machine. The uncoiler performs the operation of unwinding the coil, and the flattening machine performs the flattening operation.

[0003] Among them, the Chinese utility model patent with the patent number: ZL202223225602.6 and the patent name: A Coil Head-Finding Assembly for an Uncoiler discloses the following technical solution: A coil head-finding assembly for an uncoiler includes an uncoiler frame and a flattening machine frame. A swing arm is rotatably installed on the uncoiler frame. One end of the swing arm is fixed with a mounting plate by screws. One side of the mounting plate is fixedly installed with a motor. The output end of the motor is connected with a rotating shaft through a coupling. A pushing wheel is fixedly sleeved outside the rotating shaft. A upper pressing plate is rotatably installed on the flattening machine frame. A material blocking roller is rotatably installed at one end of the upper pressing plate. The upper pressing plate is driven by a cylinder.

[0004] When the above coil head-finding assembly for an uncoiler works, the coil is rotatably sleeved on the uncoiler frame. When it is necessary to introduce the coil into the flattening machine, the swing arm rotates under the action of a driving source and the pushing wheel contacts the outer peripheral surface of the coil. The swing arm, the motor and the pushing wheel form a coil unwinding assembly for realizing coil unwinding; the upper pressing plate rotates under the driving action of the cylinder and the material blocking roller at the rear end of the upper pressing plate fits on the outside of the coil. The upper pressing plate and the material blocking roller cooperate with each other to jointly form a material pressing assembly. The material pressing assembly presses the metal sheet drawn out by the uncoiler downward; under the action of the pushing wheel, the coil rotates slowly, and the material blocking roller rotates adaptively with the rotation of the coil, and then the metal sheet after uncoiling is sent into the flattening machine to realize the coil stripping operation.

[0005] It should be noted that during the process of the above coil head-finding assembly for an uncoiler realizing the coil stripping operation, it has the following defects, specifically:

[0006] Defect 1: The swing arm is hinged to the uncoiler frame, and the swing arm swings under the driving action of a power source. The motor and the pushing wheel installed at the free end of the swing arm swing synchronously with the swing arm. That is, the feeding movement of the pushing wheel needs to be realized by means of the swing arm, and the structure is complex;

[0007] Defect 2: The upper pressing plate swings under the driving action of the cylinder, and the material blocking wheel swings synchronously with the free end of the upper pressing plate. That is, the feeding movement of the material blocking wheel needs to be realized by means of the upper pressing plate, and the structure is complex;

[0008] Defect 3: The material pressing assembly composed of the upper pressing plate, the material blocking wheel and the corresponding cylinder is installed at the position of the leveling frame, while the uncoiling assembly composed of the swing arm, the motor and the material pushing wheel is installed on the decoiling frame. The material pressing assembly and the uncoiling assembly are separated by a relatively long distance, and the structural compactness is poor. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following combines specific embodiments to illustrate the utility model.

[0030] Embodiment 1, as Figure 1As shown in the figure, a stripping rack with improved structure includes a frame 1, and a stripping component 2 and a material pressing component 3 which are arranged at an interval from the stripping component 2 are installed on the frame 1. It should be noted that for the frame 1 of the first embodiment, it can be a part of the uncoiler 5 or a structure independent of the uncoiler 5.

[0031] Among them, as Figure 1 shown, a fixed support 4 located above the unwinding shaft of the uncoiler 5 is installed at the upper end of the frame 1, and the stripping component 2 and the material pressing component 3 are respectively installed on the fixed support 4.

[0032] Furthermore, as Figure 1 and Figure 2 shown, the stripping component 2 includes a stripping roller 21 arranged vertically aligned with the unwinding shaft of the uncoiler 5, and a stripping driving oil cylinder 22 fixedly installed on the fixed support 4 and moving vertically. The outer extension end of the piston rod of the stripping driving oil cylinder 22 is provided with a stripping lifting seat 23, and both ends of the stripping roller 21 are respectively installed on the stripping lifting seat 23 through a first bearing seat 24; a reduction motor 25 is fixedly installed beside the stripping roller 21 on the stripping lifting seat 23, and the reduction motor 25 is drivingly connected to the stripping roller 21. It should be noted that the power output shaft of the reduction motor 25 is drivingly connected to the stripping roller 21 through a chain transmission mechanism.

[0033] Even further, as Figure 1 and Figure 3 shown, the material pressing component 3 includes a material pressing driving oil cylinder 31 fixedly installed on the fixed support 4 and moving vertically. The outer extension end of the piston rod of the material pressing driving oil cylinder 31 is provided with a material pressing lifting seat 32, and a material pressing roller 34 is rotatably installed on the material pressing lifting seat 32 through a second bearing seat 33.

[0034] It should be pointed out that the material pressing component 3 of the first embodiment is located at the spatial position between the uncoiler 5 and the leveling machine.

[0035] When the stripping component 2 of the first embodiment operates, the metal coil is placed on the unwinding shaft of the uncoiler 5, the stripping driving oil cylinder 22 operates and drives the stripping lifting seat 23 to move downward, and the downward moving stripping lifting seat 23 drives the reduction motor 25 and the stripping roller 21 to move downward synchronously, so that the stripping roller 21 presses against the metal coil. During this process, the reduction motor 25 drives the stripping roller 21 to rotate, and the rotating stripping roller 21 makes the metal coil rotate, thereby realizing the stripping action of the metal coil.

[0036] For the material pressing component 3 of the first embodiment, the metal sheet stripped by the stripping component 2 passes under the material pressing component 3, the material pressing driving oil cylinder 31 operates and drives the material pressing lifting seat 32 to move downward, and the material pressing lifting seat 32 drives the material pressing roller 34 to move downward synchronously, so that the material pressing roller 34 pushes the metal sheet downward to make the metal sheet accurately enter the leveling machine.

[0037] It should be noted that the unwinding roller 21 of the first embodiment is vertically aligned with the unwinding shaft of the uncoiler 5, that is, the central axis of the unwinding roller 21 and the central axis of the unwinding shaft are located in the same vertical plane; the above alignment structure design can effectively reduce the lifting and moving stroke of the unwinding roller 21.

[0038] It should be emphasized that the unwinding roller 21 of the first embodiment is installed on the unwinding lifting seat 23, and the unwinding lifting seat 23 moves up and down under the driving action of the vertically acting unwinding driving oil cylinder 22; compared with the structure form in the prior art where the unwinding roller 21 is installed on the swing arm, the structure of the unwinding assembly 2 is simpler. Similarly, the pressure roller 34 of the first embodiment is installed on the pressure lifting seat 32, and the pressure lifting seat 32 moves up and down under the driving action of the vertically acting pressure driving oil cylinder 31; compared with the structure form in the prior art where the pressure roller 34 is installed on the upper pressure plate, the structure of the pressure assembly 3 is simpler.

[0039] In addition, in the first embodiment, the unwinding assembly 2 and the pressure assembly 3 are respectively installed on the fixed support 4. Compared with the layout structure form in the prior art, the layout structure form of the first embodiment is more compact.

[0040] Based on the above situation, through the above structure design, the improved blanking rack of the first embodiment has the advantages of novel design, simple structure and good layout compactness.

[0042] Through the guiding pair structure composed of the first guide rod 26 and the first guide sleeve 27, the second embodiment can ensure that the unwinding lifting seat 23 moves up and down accurately and smoothly.

[0043] Embodiment 3, as Figure 3 shown, the difference between the third embodiment and the first embodiment is that at least two second guide rods 35 arranged vertically are fixedly installed on the pressure lifting seat 32, and the fixed support 4 is respectively provided with second guide sleeves 36 corresponding to the second guide rods 35, and each second guide rod 35 respectively passes through the central hole of the corresponding second guide sleeve 36.
