Description

Technical Field

[0001] The present application relates to the technical field of aluminum coil processing equipment, and in particular to an aluminum coil unwinding and conveying device. Background Art

[0002] In the aluminum processing industry (such as aluminum foil, aluminum sheet, strip, and aluminum profile coating or lamination), aluminum coils are a common form of raw material storage and transportation. The fundamental reason aluminum coils require unwinding drives is that subsequent continuous processing steps require the aluminum strip to be unwound and conveyed from the reel at a stable, controllable speed and tension. The unwinding drive is the starting point of the entire continuous production line (such as slitting, cleaning, coating, printing, laminating, annealing, etc.). Its core function is to release the coiled aluminum strip smoothly and orderly, providing a continuous material supply to downstream equipment.

[0003] However, when driving the aluminum strip to move, traditional aluminum coil unwinding conveyors often encounter the problem of the aluminum strip suddenly being subjected to a large instantaneous pulling force that far exceeds the set tension. When the aluminum strip is subjected to sudden high pulling force, it is prone to plastic tensile deformation (such as local thinning and elongation) that exceeds its elastic limit, causing tensile deformation of the material, thereby affecting the processing quality of the aluminum.

[0016] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0017] The following describes the aluminum coil unwinding and conveying device according to an embodiment of the present application with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the aluminum coil unwinding and conveying device of the embodiment of the present application may include an unwinding platform 1, a conveying platform 2, a tension limiting component 3, a tension adjusting component 4, a conveying component 5 and two cutting components 6.

[0019] Wherein, an unwinding bracket 10 is provided on the unwinding platform 1 .

[0020] Specifically, an aluminum coil (not shown in the figure, and the aluminum coil includes a central support shaft) is placed on an unwinding bracket 10 and rotated, thereby unwinding the aluminum material.

[0021] The conveying platform 2 is arranged on one side of the unwinding platform 1 . A conveying bracket 20 is arranged on the conveying platform 2 . The tension limiting component 3 is arranged on the unwinding platform 1 .

[0022] In the embodiment of the present application, the tension limiting assembly 3 is used to control the tightening state of the aluminum coil to prevent the aluminum coil from losing its restraint and expanding and loosening.

[0023] Specifically, the aluminum coil is placed on the unwinding bracket 10, the tension limiting component 3 abuts the outside of the aluminum coil, and the relevant operator removes the bandage of the aluminum coil. The tension limiting component 3 continuously limits the aluminum coil, thereby preventing the aluminum coil from losing its restraint and expanding, thereby ensuring the unwinding quality of the aluminum coil.

[0024] The tension adjustment assembly 4 is disposed on the conveying platform 2 and is located between the unwinding bracket 10 and the conveying assembly 5 .

[0025] In the embodiment of the present application, the tension adjustment component 4 is used to adjust the aluminum coil from being too tight or too loose during the unwinding and transmission process, thereby ensuring the quality of the unwinding and transmission of the aluminum coil.

[0026] Specifically, the tension adjustment component 4 abuts against the aluminum sheet released from the aluminum coil. When the aluminum sheet is too tight, it abuts against the tension adjustment component 4, causing the tension adjustment component 4 to contract. When the aluminum sheet is too loose, it abuts against the tension adjustment component 4, causing the tension adjustment component 4 to extend.

[0027] The conveying assembly 5 may include a conveying motor 50 , a dynamic torque sensor 53 , a first conveying roller 51 , and a second conveying roller 52 .

[0028] The conveying motor 50 is disposed on the conveying bracket 20 , and the dynamic torque sensor 53 is disposed on the conveying bracket 20 . One end of the dynamic torque sensor 53 is connected to the conveying motor 50 , and the other end of the dynamic torque sensor 53 is connected to the first conveying roller 51 .

[0029] In the embodiment of the present application, the dynamic torque sensor 53 is used to detect the resistance of the first conveying roller 51 and the second conveying roller 52 in conveying the aluminum coil and aluminum sheet in real time, and transmit the signal to the controller (not shown in the figure).

[0030] Specifically, when a large traction force occurs, the dynamic torque sensor 53 detects that the resistance value reaches a specified range and transmits a signal to the controller. The controller sends a control signal value to cut off the conveying component 6, so that the conveying component 6 runs and no longer conveys the aluminum coil.

[0031] One end of the first conveying roller 51 is rotatably connected to the conveying bracket 20, and both ends of the second conveying roller 52 are rotatably set on the corresponding cutting components 6. The two cutting components 6 are respectively set on the conveying platform 2, and the second conveying roller 52 can slide on the cutting components 6.

[0032] In the embodiment of the present application, the cutting component 6 is used to control the distance between the second conveying roller 52 and the first conveying roller 51, thereby controlling the conveyance of the aluminum coil.

[0033] Specifically, when the cutting assembly 6 controls the second conveyor roller 52 to move away from the first conveyor roller 51, the distance between the second conveyor roller 52 and the first conveyor roller 51 increases, and this distance is much larger than the diameter of the aluminum sheet being unwound from the aluminum coil, thereby preventing the first and second conveyor rollers 51 and 52 from conveying the aluminum sheet. When the cutting assembly 6 controls the second conveyor roller 52 to move closer to the first conveyor roller 51, the first and second conveyor rollers 51 and 52 squeeze the aluminum coil and aluminum sheet, thereby conveying the aluminum coil and aluminum sheet.

[0034] Specifically, during the actual operation, the relevant operator places the aluminum coil on the unwinding bracket 10 and abuts the tension limiting component 3 against the aluminum coil. The relevant operator uses a tool (such as pliers) to release the fixing belt (not shown in the figure) wrapped around the aluminum coil and starts the device. The controller sends a control signal to control the rotation of the tension limiting component 3. The tension limiting component 3 conveys the aluminum sheet at one end of the aluminum coil. The relevant operator uses a tool to pull the conveyed aluminum sheet through the tension adjustment component 4 to between the first conveying roller 51 and the second conveying roller 52.

[0035] The controller issues a control signal to rotate the conveyor motor 50, which in turn drives the first conveyor roller 51, thereby transporting the aluminum sheet between the first conveyor roller 51 and the second conveyor roller 52, completing the unwinding and conveying of the aluminum coil. When strong traction occurs, the dynamic torque sensor 53 detects that the resistance value has reached a specified range and transmits a signal to the controller. The controller then sends a control signal to the feed assembly 6, which, upon receiving the signal, controls the second conveyor roller 52 to quickly move away from the first conveyor roller 51, allowing the pulling force to engage the aluminum sheet at the tension adjustment assembly 4. This prevents strong traction from engaging the aluminum coil and sheet, which could cause tearing and other quality issues.

[0036] In one embodiment of the present application, Figure 1 、 Figure 3 and Figure 4 As shown, the disconnecting assembly 6 may include a mounting housing 60 , an electromagnetic attractor 61 , an adsorption block 62 and an elastic pulling block 63 .

[0037] Among them, the mounting shell 60 is arranged on the conveying platform 2, the electromagnetic adsorber 61 is arranged on the mounting shell 60, the adsorption block 62 is electromagnetically adsorbed and connected to the electromagnetic adsorber 61, and the adsorption block 62 is slidingly connected to the mounting shell 60, one end of the second conveying roller 52 passes through the sliding groove opened on the conveying platform 2 and is rotatably connected to the adsorption block 62, one end of the elastic pull block 63 is connected to the mounting shell 60, and the other end of the elastic pull block 63 is connected to the adsorption block 62.

[0038] It should be noted that the position of the electromagnetic absorber 61 described in this example is adjustable, so that the distance between the first conveying roller 51 and the second conveying roller 52 is adjustable, so as to be suitable for aluminum coils and aluminum sheets of different thicknesses.

[0039] It should be noted that the electromagnetic adsorber 61 described in this embodiment is a common electromagnetic adsorber device on the market and is a prior art, and will not be described in detail here.

[0040] In one embodiment of the present application, Figure 1 、 Figure 3 and Figure 4 As shown, the elastic pulling block member 63 may include two elastic telescopic cylinders 630 .

[0041] One end of the two elastic telescopic tubes 630 is connected to the mounting shell 60 , and the other end of the two elastic telescopic tubes 630 is connected to the adsorption block 62 .

[0042] It should be noted that the elastic telescopic tube 630 described in this embodiment is a common elastic telescopic component on the market and is a prior art, so it will not be described in detail here.

[0043] In one embodiment of the present application, Figure 1 、 Figure 3 and Figure 4 As shown, the delivery assembly 6 may further include an electric telescopic rod 64 .

[0044] One end of the electric telescopic rod 64 is connected to the mounting housing 60 , and the other end of the electric telescopic rod 64 is connected to the adsorption block 62 .

[0045] In the embodiment of the present application, the electric telescopic rod 64 is used to push the adsorption block 62 to reset, so that it is re-adsorbed by the electromagnetic adsorber 61, thereby eliminating the need for relevant staff to manually adjust the adsorption state of the electromagnetic adsorber 61 and the adsorption block 62.

[0046] In one embodiment of the present application, Figure 1 、 Figure 3 and Figure 4 As shown, the tension limiting assembly 3 may include a driving motor 30 , a limiting bracket 31 and a limiting roller 32 .

[0047] The driving motor 30 is arranged on the unwinding platform 1 , the limiting bracket 31 is rotatably arranged on the unwinding platform 1 , the output shaft of the driving motor 30 is connected to the limiting bracket 31 , and the limiting roller 32 is rotatably arranged on the limiting bracket 31 .

[0048] It should be noted that the limiting roller 32 described in this embodiment is provided with an auxiliary motor (not shown in the figure). Through the setting of the auxiliary motor, when the limiting roller 32 abuts against the aluminum coil, it can drive one end of the aluminum coil to extend out, thereby eliminating the need for the relevant operator to manually pull it out, thereby reducing the labor intensity of the relevant operator.

[0049] Specifically, as the aluminum coil is gradually unwound and transported, the diameter of the aluminum coil becomes smaller and smaller. The drive motor 30 can rotate along with the aluminum coil with gradually decreasing diameter, so that the limiting roller 32 is always in contact with the aluminum coil, thereby ensuring the unwinding quality of the aluminum coil.

[0050] In one embodiment of the present application, Figure 1 、 Figure 3 and Figure 4 Figure 1 Figure 3 Figure 4 As shown, the tension adjustment assembly 4 may include an adjustment roller 40 and two elastic support cylinders 41 .

[0051] The two ends of the adjusting roller 40 are respectively connected to the corresponding elastic support tubes 41 , one end of the two elastic support tubes 41 is rotatably connected to the adjusting roller 40 , and the other ends of the two elastic support tubes 41 are respectively connected to the conveying platform 2 .

[0052] It should be noted that the elastic support tube 41 described in this embodiment is a common elastic telescopic component on the market and is a prior art, so it will not be described in detail here.

[0053] Specifically, during the actual operation, the relevant operator places the aluminum coil on the unwinding bracket 10, and the controller transmits a control signal to control the drive motor 30 to rotate. The drive motor 30 drives the limit bracket 31 to rotate and drives the limit roller 32 to rotate, so that the limit roller 32 abuts against the surface of the aluminum coil, thereby abutting and limiting the aluminum coil. The relevant operator uses a tool (such as pliers) to release the fixing belt (not shown in the figure) fixed around the aluminum coil, and starts the device. The controller sends a control signal to control the auxiliary motor to rotate. The auxiliary motor drives the limit roller 32 to rotate and conveys the aluminum sheet at one end of the aluminum coil. The relevant operator uses a tool to pull the conveyed aluminum sheet through the adjustment roller 40 in the tension adjustment assembly 4 to between the first conveying roller 51 and the second conveying roller 52, so that the first drive roller and the second conveying roller 52 abut against the aluminum sheet, thereby facilitating the conveying control of the aluminum sheet.

[0054] The controller sends a control signal to control the rotation of the conveyor motor 50, which in turn drives the first conveyor roller 51 to rotate, thereby moving the aluminum sheet between the first conveyor roller 51 and the second conveyor roller 52, thereby completing the unwinding and conveying of the aluminum coil. When a strong pulling force occurs, the dynamic torque sensor 53 detects that the resistance value has reached a specified range and transmits a signal to the controller. The controller sends a control signal to the corresponding disconnection component 6. After receiving the signal, the disconnection component 6 controls the electromagnetic attractor 61 to release the attraction block 62. After releasing the attraction block 62, the electromagnetic attractor 61 rapidly descends under the tension of the elastic telescopic rod, causing the second conveyor roller 52 to quickly move away from the first conveyor roller 51. This pulling force pulls the aluminum sheet on the adjustment roller 40 and drives the elastic support tube 41 to contract. This prevents the strong pulling force from pulling the aluminum coil and sheet, which can cause tearing and other quality problems.

[0055] When the above-mentioned traction problem is solved, the controller sends a control signal to extend the electric telescopic rod 64. The extension of the electric telescopic rod 64 drives the adsorption block 62 to move upward, so that the adsorption block 62 abuts against the electromagnetic adsorber 61. The controller sends a signal to operate the electromagnetic adsorber 61 and adsorb and fix the adsorption block 62, thereby continuing to convey the aluminum coil and aluminum sheet.

[0056] In summary, the aluminum coil unwinding and conveying device of the embodiment of the present application can disconnect the transmission of the aluminum coil when a large traction force occurs through real-time detection of the traction force of the aluminum material, thereby ensuring the unwinding quality of the aluminum coil.
