Description

Technical Field

[0001] This utility model relates to the field of aluminum coil production technology, specifically to a device for tilting the anti-loosening layer during the transportation of longitudinally slit aluminum coils. Background Technology

[0002] Slitting aluminum coils is a common process in aluminum coil processing. After the finished aluminum coils are processed, they are conveyed to the slitting line, where large aluminum coils are cut into smaller coils according to the width and length required by the customer. Through slitting, aluminum coils can be cut into smaller coils of different widths to meet the needs of various application scenarios. The slitting line typically includes core components such as an uncoiler, a guiding device, a disc shear, a tension control device, and a winding machine. The uncoiler is responsible for unwinding the aluminum coil, the guiding device ensures that the aluminum strip enters the cutting area smoothly, the disc shear consists of two blades, and different widths of aluminum coils can be slit by adjusting the distance between the blades, and the winding machine is used to wind up the slitted aluminum strip to form aluminum coils again.

[0003] In the existing technology, after aluminum coils are wound onto the winding machine's expansion shaft, they can be packaged on-machine. However, the on-machine packaging time is long, which affects the production efficiency of aluminum coils. When the aluminum coils are removed from the winding machine by the coil transport trolley for off-machine packaging, the aluminum coils are prone to loosening during transport, resulting in low packaging efficiency. At the same time, multiple aluminum coils are prone to tilting to both sides, causing damage to the aluminum coils. Summary of the Invention

[0004] This invention addresses the problem of loose layers and tipping when multiple aluminum coils are transported by existing trolleys. It provides a device to prevent loose layers and tipping during the transport of slitting aluminum coils. This device can hold down the heads of multiple aluminum coils, effectively preventing loose layers during transport. It can also limit the movement of multiple aluminum coils to prevent them from tipping to the sides.

[0005] To achieve the above objectives, the technical solution of this utility model is: a device for transporting and preventing the anti-loosening layer of longitudinally slitting aluminum coils, comprising a coil transport trolley, a support frame fixedly mounted on one side of the coil transport trolley, roller assemblies spaced apart at the bottom of the support frame, drive assemblies mounted on both sides of the support frame, and a pressure roller frame rotatably mounted on the upper end of the support frame, the lower end of the pressure roller frame being connected to the drive assemblies. The roller assemblies facilitate the movement of the support frame by the coil transport trolley, while preventing the coil transport trolley from tipping over due to excessive weight on one side. The drive assemblies can drive the pressure roller frame to rotate.

[0006] Multiple pressure roller assemblies are spaced apart at the upper end of the pressure roller frame. Each pressure roller assembly includes a pressure roller connecting plate, a guide rod, and a spring. The pressure roller connecting plate is located below the pressure roller frame, with one end hinged to the frame and the other end having a pressure roller at its bottom. The guide rod is slidably sleeved on the pressure roller frame, with its lower end hinged to the connecting plate and its upper end having a limiting component. The spring is sleeved on the guide rod and located between the pressure roller frame and the connecting plate. The drive assembly rotates the pressure roller frame, causing the pressure roller assemblies to rotate so that they press against the heads of multiple aluminum coils, preventing loosening during transport. The pressure rollers of the assembly press down on the heads of the aluminum coils. When the pressure rollers contact the aluminum coils, the guide rod slides upward, compressing the spring. The elastic force of the spring acts on the connecting plate, ensuring the pressure rollers press against the heads of the aluminum coils to prevent loosening.

[0007] Furthermore, the support frame includes a fixed base and two booms symmetrically arranged on top of the fixed base, with support rods spaced apart between the two booms. The fixed base is connected to the winding trolley. The roller assembly is located at the bottom of the fixed base, and the support rods are used to connect the two booms, serving to stabilize and strengthen the structure.

[0008] Furthermore, the roller assembly includes a roller seat, a roller, and a bearing. The roller seat is fixedly disposed at the bottom of the fixed base, and a roller shaft is fixedly disposed on the roller seat. The roller is located inside the roller seat and rotatably sleeved on the roller shaft. The bearing is disposed between the roller and the roller shaft, and a bearing cover is disposed on one side of the roller. The bearing cover is rotatably sleeved on the roller shaft. The bearing facilitates the rotation of the roller on the roller shaft, thereby facilitating the movement of the support frame with the winding trolley. The bearing cover also serves to limit the movement of the bearing.

[0009] Furthermore, a rotating shaft is fixedly provided on the outer side of the upper end of the boom, and a hinge seat is provided on the outer side of the lower end; the drive assembly includes a hydraulic cylinder and a connecting arm, the lower end of the hydraulic cylinder is provided with an ear plate that is hinged to the hinge seat, the middle part of the connecting arm is rotatably sleeved on the rotating shaft, the lower end of the connecting arm is hinged to the piston rod of the hydraulic cylinder, and the upper end is connected to the pressure roller frame, and the extension and retraction movement of the piston rod of the hydraulic cylinder can drive the connecting arm to rotate on the rotating shaft.

[0010] Furthermore, the pressure roller frame includes pressure roller columns and a rotating arm connected to two pressure roller columns. The lower end of the rotating arm is rotatably sleeved on the rotating shaft. A fixed shaft is provided between the upper end of the rotating arm and the connecting arm. The two ends of the fixed shaft are respectively connected to the rotating arm and the connecting arm. When the piston rod of the hydraulic cylinder drives the connecting arm to rotate on the rotating shaft, under the action of the fixed shaft, the connecting arm can drive the rotating arm to rotate on the rotating shaft, so that the rotating arm drives the pressure roller columns to rotate, thereby achieving the purpose of the pressure roller assembly pressing on or separating from the aluminum coil head.

[0011] Furthermore, multiple pressure roller assemblies are spaced apart on the pressure roller column, and multiple through holes are spaced apart on the pressure roller column. The lower end of the guide rod passes through the through hole and is hinged to the pressure roller connecting plate. The through hole facilitates the sliding of the guide rod on the pressure roller column, thereby facilitating the compression of the spring by the pressure roller connecting plate.

[0012] Furthermore, the limiting component is a limiting nut, which is threadedly connected to the guide rod; multiple hinged bases are spaced apart at the bottom of the pressure roller column, and the upper end of the pressure roller connecting plate is hinged to the hinged base. The limiting nut limits the guide rod to prevent it from sliding downward and detaching from the pressure roller column, and the hinged base facilitates the rotation of the pressure roller connecting plate.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] This utility model has a reasonable structure and good performance. It can press down the heads of multiple aluminum coils according to the diameter of the aluminum coil, so as to effectively avoid the phenomenon of loose layers when multiple aluminum coils are transported on the coil transport trolley, thereby improving the packaging efficiency of aluminum coils. At the same time, it can also limit the two sides of multiple aluminum coils, thereby preventing multiple aluminum coils from tilting to both sides. It can also allow the coil transport trolley to transport multiple aluminum coils out of the coiler for external packaging, thereby improving the production efficiency and packaging efficiency of aluminum coils.

[0015] The roller assembly at the bottom of the support frame of this utility model allows the winding trolley to move the support frame, and also provides support to prevent the winding trolley from tipping over due to excessive weight on one side. The bearing of the roller assembly facilitates the rotation of the roller on the roller shaft, so that the support frame can follow the movement of the winding trolley. The bearing cap limits the bearing and prevents the bearing from moving axially on the roller shaft.

[0016] The piston rod of the hydraulic cylinder of this utility model can drive the connecting arm to rotate on the rotating shaft by telescopic movement. Under the action of the fixed shaft, the connecting arm can drive the rotating arm to rotate on the rotating shaft. The rotating arm drives the pressure roller to rotate so that the pressure roller assembly presses on the head of multiple aluminum coils or detaches from the head of the aluminum coils, thereby avoiding the loosening of multiple aluminum coils during transportation on the coil transport trolley.

[0017] After the pressure roller of this utility model contacts the surface of the aluminum coil, the pressure roller connecting plate can drive the guide rod to slide upward on the pressure roller column. At the same time, the spring is compressed by the pressure amount. The elastic force of the spring acts on the pressure roller connecting plate to make the pressure roller press on the head of the aluminum coil, thereby avoiding the phenomenon of loose layers when multiple aluminum coils are transported on the coil transport trolley. The pressure roller assemblies located at both ends of the pressure roller column do not contact the aluminum coil, and the springs of the pressure roller assemblies are not compressed. The pressure rollers of the non-contacting pressure roller assemblies block the sides of the aluminum coil, thereby preventing multiple aluminum coils from tilting to both sides.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-4 As shown, a device for tilting the anti-loosening layer during the transport of slitting aluminum coils includes a coil transport trolley 1. A support frame is fixedly installed on one side of the coil transport trolley 1. Roller assemblies are spaced apart at the bottom of the support frame. Drive assemblies are installed on both sides of the support frame. A pressure roller frame is rotatably installed at the upper end of the support frame, and the lower end of the pressure roller frame is connected to the drive assemblies. In this embodiment, a track is arranged on one side of the coil transport trolley, and the roller assemblies are located on the track. At least two roller assemblies are symmetrically installed at the bottom of the support frame. The cooperation between the roller assemblies and the track facilitates the movement of the support frame by the coil transport trolley. There are two drive assemblies, located on both sides of the support frame. The drive assemblies can drive the pressure roller frame to rotate on the support frame. The pressure roller frame has an overall "U"-shaped structure.

[0025] A plurality of pressure roller assemblies are arranged at intervals on the upper end of the pressure roller frame. The pressure roller assembly includes a pressure roller connecting plate 16, a guide rod 18 and a spring 20. The pressure roller connecting plate 16 is located below the pressure roller frame. One end of the pressure roller connecting plate 16 is hinged to the pressure roller frame, and a pressure roller 17 is provided at the bottom of the other end. The guide rod 18 is slidably sleeved on the pressure roller frame. The lower end of the guide rod 18 is hinged to the pressure roller connecting plate 16, and a limiting member is provided at the upper end. The spring 20 is sleeved on the guide rod 18 and is located between the pressure roller frame and the pressure roller connecting plate 16. In this embodiment, the number of pressure roller assemblies is 27. When the driving component drives the pressure roller frame to move downward, after the pressure roller 17 contacts the aluminum coil surface, the pressure roller connecting plate 16 rotates and pushes the guide rod 18 to slide upward on the pressure roller frame, and the spring 20 is compressed by the pressing amount. The elastic force of the spring 20 acts on the pressure roller connecting plate 16, and the pressure roller connecting plate 16 makes the pressure roller 17 press on the head of the aluminum coil material.

[0026] The support frame includes a fixed seat 2 and two armrests 8 symmetrically arranged on the top of the fixed seat 2. A support rod 9 is arranged at intervals between the two armrests 8. The fixed seat 2 is connected to the coil transporting trolley 1; the roller assembly is arranged at the bottom of the fixed seat 2. In this embodiment, the number of support rods 9 between the two armrests 8 is two. The two ends of the support rod 9 are respectively connected to the two armrests 8. The support rod 9 is used to connect the two armrests 8 and plays a role in stabilizing and strengthening.

[0027] The roller assembly includes a roller seat 3, a roller 5 and a bearing 6. The roller seat 3 is fixedly arranged at the bottom of the fixed seat 2. A roller shaft 4 is fixedly arranged on the roller seat 3. The roller 5 is located in the roller seat 3 and is rotatably sleeved on the roller shaft 4; a bearing 6 is arranged between the roller 5 and the roller shaft 4. A bearing gland 7 is arranged on one side of the roller 5, and the bearing gland 7 is rotatably sleeved on the roller shaft 4. In this embodiment, the roller seat 3 has an inverted "U" - shaped structure, the roller 5 has a "convex" - shaped structure, and the roller 5 is located on the track. When the coil transporting trolley 1 moves, the roller 5 moves on the track; there is a shoulder inside the roller 5, the purpose of which is to limit the bearing 6. The bearing gland 7 is bolt - fixed on one side of the roller 5, the purpose of which is to limit the bearing 6. Through the bearing 6, it is convenient for the roller 5 to rotate on the roller shaft 4, so as to facilitate the coil transporting trolley to drive the support frame to move.

[0028] The upper outer side of the boom 8 is fixedly provided with a rotating shaft 801, and the lower outer side is provided with a hinge seat. The drive assembly includes a hydraulic cylinder 10 and a connecting arm 12. The lower end of the hydraulic cylinder 10 is provided with an ear plate 11 that is hinged to the hinge seat. The middle part of the connecting arm 12 is rotatably sleeved on the rotating shaft 801. The lower end of the connecting arm 12 is hinged to the piston rod of the hydraulic cylinder 10, and the upper end is connected to the pressure roller frame. In this embodiment, the ear plate 11 is connected to the hinge seat by a pin. The piston rod end of the hydraulic cylinder 10 is equipped with a U-shaped seat, which is connected to the connecting arm 12 by a pin. The extension and retraction of the piston rod of the hydraulic cylinder 10 drives the connecting arm 12 to rotate on the rotating shaft 801.

[0029] The pressure roller frame includes pressure roller columns 14 and rotating arms 13 connected to two of the pressure roller columns 14. The lower end of the rotating arm 13 is rotatably sleeved on the rotating shaft 801. A fixed shaft is provided between the upper end of the rotating arm 13 and the connecting arm 12, and the two ends of the fixed shaft are respectively connected to the rotating arm 13 and the connecting arm 12. In this embodiment, when the piston rod of the hydraulic cylinder 10 moves in a telescopic motion, driving the connecting arm 12 to rotate, the connecting arm 12 drives the rotating arm 13 to rotate on the rotating shaft 801 through the fixed shaft. The rotating arm 13 drives the pressure roller columns 14 to rotate, and the pressure roller columns 14 drive the pressure roller assembly to rotate to press against or detach from the aluminum coil.

[0030] Multiple pressure roller assemblies are spaced apart on the pressure roller column 14, and multiple through holes are spaced apart on the pressure roller column 14. The lower end of the guide rod 18 passes through the through hole and is hinged to the pressure roller connecting plate 16. In this embodiment, the guide rod 18 is slidably fitted into the through hole, and the through hole facilitates the pressure roller connecting plate 16 to push the guide rod 18 to slide on the pressure roller shaft 14, thereby facilitating the compression of the spring 20 by the pressure amount.

[0031] The limiting component is a limiting nut 19, which is threadedly connected to the guide rod 18. Multiple hinged bases 15 are spaced apart at the bottom of the pressure roller column 14, and the upper end of the pressure roller connecting plate 16 is hinged to the hinged bases 15. In this embodiment, the limiting nut 19 limits the guide rod 18 to prevent it from sliding downwards and disengaging from the pressure roller column 14, while the hinged bases 15 facilitate the rotation of the pressure roller connecting plate to push the guide rod 18.

[0032] The working principle of this utility model is as follows: After the slit aluminum coil is wound onto the winding machine's expansion shaft, the winding trolley 1 is moved to the center position of the aluminum coil. Then, the hydraulic cylinders 10 of the two drive components are opened. The piston rods of the hydraulic cylinders 10 extend and drive the connecting arm 12 to rotate on the rotating shaft 801. The connecting arm 12 of the two drive components drives the pressure roller frame to rotate on the rotating shaft 801 through the fixed shaft. The pressure roller column 14 drives the pressure roller assembly to move downward. According to the diameter of the slit aluminum coil, after the pressure roller 17 contacts the surface of the aluminum coil, the pressure roller connecting plate 16 rotates and pushes the guide rod. 18 slides upward on the pressure roller frame, and the spring 20 is compressed by the pressure amount. The elastic force of the spring 20 acts on the pressure roller connecting plate 16, and the pressure roller connecting plate 16 makes the pressure roller 17 press on the aluminum coil head to avoid the phenomenon of loose layers in the aluminum coil. The pressure roller assemblies located at both ends of the pressure roller column 14 do not contact the aluminum coil, that is, the spring 20 of the pressure roller assembly is not compressed and the pressure roller 17 does not contact the aluminum coil. The pressure roller 17 of the non-contact pressure roller assembly blocks the side of the aluminum coil to prevent the aluminum coil from tilting. Then the coil transport trolley 1 can drive the slitting aluminum coil out of the coiler for external packaging.
