Description

Technical Field

[0001] This utility model belongs to the field of materials processing, and specifically relates to a multi-functional uncoiling and leveling machine. Background Technology

[0002] Uncoiling and leveling machines are essential equipment in the field of metal sheet processing. They are mainly used to uncoil and level coiled steel strips and then transport them to subsequent processing equipment.

[0003] However, traditional uncoiling leveling machines typically have a layout with only a single leveling device, which can only handle the leveling output of a single coil of steel strip material. This makes them unsuitable for processing equipment that can process double-layer steel strips, resulting in existing processing equipment only being able to process single-layer steel strips.

[0004] Therefore, there is a market demand for a multi-functional uncoiling and leveling machine that can simultaneously uncoil and level two steel strips and then output them together, thus matching the processing equipment for double-layer steel strips. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-functional uncoiling and leveling machine that can simultaneously uncoil and level two steel strips and then output them together.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a multi-functional uncoiling and leveling machine, including a material rack for loading coils, a leveling mechanism for leveling coils, and a conveying mechanism for conveying steel strips disposed between the material rack and the leveling mechanism. The material rack includes a first material rack and a second material rack. The leveling mechanism includes a leveling frame column, a first leveling device and a second leveling device that can be raised and lowered respectively on the leveling frame column, and a steel strip output device disposed on the leveling frame column and located between the first leveling device and the second leveling device. The conveying mechanism includes a first conveyor belt connected between the first material rack and the first leveling device, and a second conveyor belt connected between the second material rack and the second leveling device. The steel strips output by the first leveling device and the second leveling device are both output through the steel strip output device.

[0007] In some embodiments, the steel strip output device includes an upper arc-shaped feeding plate and a lower arc-shaped feeding plate symmetrically positioned at the input end of the discharge channel. The two feeding plates form a trumpet-shaped feeding inlet of the discharge channel. The leveling unit inside the first leveling device and the leveling unit inside the second leveling device are also symmetrically arranged vertically.

[0008] In some embodiments, the first leveling device includes an upper bracket plate whose upper end is rotatably disposed at the output port of the first leveling device via a rotation drive component, and an upper steel strip guide frame whose upper end is rotatably disposed at the output port of the first leveling device and located inside the upper bracket plate. The upper steel strip guide frame and the upper bracket plate form an upper guide channel for outputting steel strip. When a new first roll of steel strip is output by the first leveling device and automatically fed into the steel strip output device, the first leveling device descends so that the lower end of the upper bracket plate covers the outside of the upper arc-shaped feed plate and faces the upper bracket plate. The second leveling device includes a lower bracket plate rotatably mounted at the output port of the second leveling device via a rotation drive component at its lower end, and a lower steel strip guide fixedly mounted at the output port of the second leveling device and located inside the lower bracket plate. The lower steel strip guide and the lower bracket plate form a lower guide channel for outputting steel strip. When a new second roll of steel strip is output by the second leveling device and automatically fed into the steel strip output device, the second leveling device rises so that the upper end of the lower bracket plate covers the outside of the lower arc-shaped feed plate and faces the horn-shaped feed inlet.

[0009] In some embodiments, during the normal output process of the steel strip from the first coil after passing through the first leveling device, the first leveling device rises, and the upper bracket and the upper steel strip guide are raised upwards respectively. An upper buffer frame for receiving the steel strip from the first coil is fixed on the steel strip output device. During the normal output process of the steel strip from the second coil after passing through the second leveling device, the second leveling device descends, and the lower bracket flattens downwards. A lower buffer frame for receiving the steel strip from the second coil is fixed on the second leveling device.

[0010] In some embodiments, the steel strip output device includes a front upper cover plate and a front lower cover plate forming the front part of the discharge channel, a rear upper pressure roller group and a rear lower pressure roller group forming the rear part of the discharge channel, and further includes a steel strip merging and alignment device disposed between the rear upper pressure roller group and the rear lower pressure roller group for aligning the left and right sides of the steel strip of the first roll and the steel strip of the second roll passing through.

[0011] In some embodiments, the steel strip merging and alignment device includes a threaded rod with positive and negative threads at both ends that is rotatably set and parallel to the upper and lower pressure rollers, and two translation adjustment limit blocks that are rotatably sleeved at both ends of the threaded rod. The two translation adjustment limit blocks are respectively blocked on the left and right sides of the steel strip of the first coil and the steel strip of the second coil.

[0012] In some embodiments, the steel strip output device is mounted on the leveling frame column and is capable of being raised and lowered.

[0013] In some embodiments, the first material rack and the second material rack each have a steel strip guide frame, the steel strip guide frame having an arc-shaped guide cover plate and multiple arc-shaped guide rollers disposed below the arc-shaped guide cover plate, the multiple arc-shaped guide rollers being distributed parallel to each other along the arc direction of the arc-shaped guide cover plate.

[0014] In some embodiments, it also includes a horizontal output roller group located at the top and multiple horizontal guide rollers that cooperate with the horizontal output roller group.

[0015] In some embodiments, the upper steel strip guide frame is provided with an upper arc-shaped guide bar, a lower arc-shaped guide bar, and a guide wheel arranged sequentially from top to bottom. When a new first roll of steel strip is output through the first leveling device, the head of the new first roll of steel strip touches the upper arc-shaped guide bar and the lower arc-shaped guide bar in sequence, and then is output downward between the guide wheel and the upper bracket plate.

[0016] The scope of this utility model is not limited to technical solutions formed by specific combinations of the above-mentioned technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-mentioned technical features or their equivalent features. For example, technical solutions formed by substituting the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a multi-functional uncoiling and leveling machine. By sequentially arranging a first leveling device, a steel strip output device, and a second leveling device from top to bottom on the leveling frame column, the first leveling device receives the steel strip from the first material rack, levels it, and then inputs it into the steel strip output device. The second leveling device receives the steel strip from the second material rack, levels it, and then inputs it into the steel strip output device. Finally, the upper and lower steel strips are merged in the steel strip output device and output synchronously, thereby matching the processing application of double-layer steel strip processing equipment and improving processing efficiency.

[0024] I. Overall Structure and Connections

[0025] like Figure 1-4 As shown, the multi-functional unwinding and leveling machine provided in this embodiment mainly consists of the following components:

[0026] Dual-feed rack system:

[0027] The system includes a first rack 2a and a second rack 2b, which are arranged in parallel with the steel strip coils loaded during use. The first rack 2a and the second rack 2b each have a base, a steel strip shaft seat rotatably connected to the base via a vertical axis for mounting the steel strip coil, and a steel strip guide frame 21 mounted on the steel strip shaft seat and located above the circumference of the steel strip coil. A power drive device is provided between the steel strip shaft seat and the base to drive the steel strip shaft seat to rotate within a 180° range for automatic switching between the uncoiling working position and the steel strip coil loading position.

[0028] Each steel strip guide frame 21 has an arc-shaped guide cover plate 22 extending along the circumference of the steel strip coil, and multiple arc-shaped guide rollers 23 arranged below the arc-shaped guide cover plate 22 and parallel to the axial direction of the steel strip coil. The multiple arc-shaped guide rollers 23 are distributed parallel to the length direction of the arc-shaped guide cover plate 22. It also includes a horizontal output roller group 24 located at the top and multiple horizontal guide rollers that cooperate with the horizontal output roller group 24. A steel strip conveying channel is formed between each arc-shaped guide cover plate 22 and arc-shaped guide roller 23, and between the corresponding horizontal output roller group 24 and horizontal guide rollers.

[0029] Transmission mechanism:

[0030] It includes a first conveyor belt 31 for receiving the steel strip output from the first material rack 2a and a second conveyor belt 32 for receiving the steel strip output from the second material rack 2b. Each conveyor belt is composed of multiple transmission rollers arranged side by side. The winding power mechanism on the steel strip shaft seat controls the rotation of the steel strip winding, so that the unwound steel strip enters between the arc-shaped guide cover plate 22 and the arc-shaped guide roller 23, and is output between the horizontal output roller group 24 and the horizontal guide roller, and then inputs into its corresponding conveyor belt for transmission.

[0031] Detailed structure of the leveling mechanism:

[0032] The system includes a leveling frame column 11, a first leveling device 12 and a second leveling device 13 that are respectively raised and lowered on the leveling frame column 11. The first leveling device 12 and the second leveling device 13 are respectively raised and lowered on the upper and lower sides of the slide rail of the leveling frame column 11 via a lifting mechanism. The leveling units inside the first leveling device 12 and the leveling units inside the second leveling device 13 are arranged symmetrically in the upper and lower positions. The first leveling device 12 is connected to the outer first material rack 2a and the upper first conveyor belt 31, and the second leveling device 13 is connected to the inner second material rack 2b and the lower second conveyor belt 32. The steel belts output by the two do not interfere with each other.

[0033] Among them, the straightening mechanism also has key structures:

[0034] The first leveling device 12 includes an upper bracket plate 121, the upper end of which is rotatably mounted at the output port of the first leveling device 12 via a rotating cylinder, and an upper steel strip guide 122, the upper end of which is rotatably mounted at the output port of the first leveling device 12 and located inside the upper bracket plate 121. The upper steel strip guide 122 and the upper bracket plate 121 form an upper guide channel for outputting steel strip. The upper steel strip guide 122 has a special structure for guiding the output of steel strip, especially for the automatic guide of the end of the steel strip of the new first roll when it is just uncoiled. The upper steel strip guide 122 is provided with an upper arc-shaped guide bar, a lower arc-shaped guide bar and a guide wheel arranged sequentially from top to bottom. When the steel strip of the new first roll is output by the first leveling device 12, the head of the steel strip of the new first roll touches the upper arc-shaped guide bar and the lower arc-shaped guide bar in sequence, and then is output downward between the guide wheel and the upper bracket plate.

[0035] The second leveling device 13 includes a lower bracket plate 131 at the lower end of which is rotatably disposed at the output port of the second leveling device 13 via a rotating cylinder, and a lower steel strip guide frame 132 fixedly disposed at the output port of the second leveling device 13 and located inside the lower bracket plate 131. The lower steel strip guide frame 132 and the lower bracket plate 131 form a lower guide channel for outputting steel strip.

[0036] The upper bracket 121 of the first leveling device 12 and the lower bracket 131 of the second leveling device 13 adjust their opening angles by rotating cylinders, which can cooperate with the steel strip output device 14 to automatically input the ends of the new first and second rolls of steel strip into the steel strip output device 14.

[0037] Detailed structure of the steel belt combined output device:

[0038] The steel belt output device 14 is mounted on the slide rail of the leveling frame column 11 and is located between the first leveling device 12 and the second leveling device 13. The device can be raised and lowered by the lifting mechanism.

[0039] The steel strip output device 14 includes a horn-shaped feed inlet for receiving double-layer steel strips, a front upper cover plate and a front lower cover plate located behind the horn-shaped feed inlet to form the front of the discharge channel, a rear upper pressure roller group and a rear lower pressure roller group to form the rear of the discharge channel, and a steel strip merging and alignment device 144. The horn-shaped feed inlet is formed by an upper arc-shaped feed plate 141 and a lower arc-shaped feed plate 142 located symmetrically at the input end of the discharge channel.

[0040] A steel strip merging and alignment device 144 is installed between the upper and lower rear pressure roller groups to align the left and right sides of the steel strips from the first and second rolls. It includes a threaded rod with positive and negative threads at both ends, rotatably mounted and parallel to the upper and lower pressure rollers, and two translation adjustment limit blocks rotatably fitted at both ends of the threaded rod. The two translation adjustment limit blocks respectively block the left and right sides of the steel strips from the first and second rolls. By rotating a handwheel at the end of the threaded rod, the positive and negative threads at both ends of the threaded rod drive the two translation adjustment limit blocks to move towards or away from the center, adjusting the appropriate width and locking them at the left and right edges of the steel strips from the first and second rolls, forcing the upper and lower steel strips to align.

[0041] II. Detailed Description of Processing Methods for Steel Strip Uncoiling Position

[0042] Step 1: Synchronous feeding and leveling of dual-belt coils

[0043] After the first coil of steel belt on the first material rack 2a is output into the first conveyor belt 31, it is sent into the first leveling device 12. After leveling, it is output from the upper guide channel and fed into the horn feed inlet of the steel belt output device 14.

[0044] After the steel strip from the second coil on the second material rack 2b is output into the second conveyor belt 32, it is sent into the second leveling device 13. After leveling, it is output from the lower guide channel and fed into the horn feed inlet of the steel strip output device 14.

[0045] Step 2: Alignment and Merging of Parallel Steel Strips

[0046] The steel strips from the first and second rolls are aligned in width by the steel strip merging and aligning device 144 of the steel strip output device 14, and then enter between the upper and lower pressure roller groups. Through roller pressing, the upper and lower layers are tightly bonded together to form a continuous double-layer steel strip output.

[0047] III. Detailed Description of the New Automatic End Feeding Method for Coiled Steel Strip

[0048] Step 1: The first leveling device 12 descends, and simultaneously the upper bracket plate 121 adjusts its opening angle by rotating the cylinder, so that the lower end of the upper bracket plate 121 covers the outside of the upper arc-shaped feeding plate 141 and faces the horn-shaped feeding inlet; the second leveling device 13 rises, and simultaneously the lower bracket plate 131 adjusts its opening angle by rotating the cylinder, so that the upper end of the lower bracket plate 131 covers the outside of the lower arc-shaped feeding plate 142 and faces the horn-shaped feeding inlet. The arc curvature of the upper arc-shaped feeding plate 141 and the lower arc-shaped feeding plate 142 matches the rotation trajectory of the upper bracket plate 121 and the lower bracket plate 131, respectively, to ensure that the steel strip is smoothly fed into the horn-shaped feeding inlet of the steel strip output device 14.

[0049] Step 2: Synchronous feeding and leveling of dual-belt coils

[0050] After the first coil of steel strip on the first material rack 2a is output into the first conveyor belt 31, it is fed into the first leveling device 12. After leveling, it is output through the upper guide channel of the upper steel strip guide frame 122 and guided by the upper arc-shaped feed plate 141 into the trumpet feed inlet. The guide wheel at the end of the upper steel strip guide frame 122 cooperates with the upper arc-shaped guide bar and the lower arc-shaped guide bar. When a new first coil of steel strip is output through the first leveling device 12, the head of the new first coil of steel strip touches the upper arc-shaped guide bar and the lower arc-shaped guide bar in sequence, and then outputs downward between the guide wheel and the upper arc plate. The lateral position of the first coil of steel strip is finely adjusted to prevent deviation during feeding.

[0051] After the steel strip of the second coil on the second material rack 2b is output into the second conveyor belt 32, it is sent into the second leveling device 13. After leveling, it is output through the lower guide channel of the lower steel strip guide frame 132 and guided by the lower arc-shaped feed plate 142 to be fed into the trumpet feed inlet.

[0052] Step 3: Alignment and Merging of Parallel Steel Strips

[0053] The steel strips from the first and second rolls are aligned in width by the steel strip merging and aligning device 144 of the steel strip output device 14, and then enter between the upper and lower pressure roller groups. The upper and lower layers are tightly bonded by the rollers to form a continuous double-layer steel strip output.

[0054] With the double-layer steel strip output and automatic feeding successful, the first leveling device 12 rises, and the upper bracket plate 121 and the upper steel strip guide frame 122 are raised simultaneously so that the steel strip of the first roll that continues to be output forms a buffer in the upper buffer frame 143; at the same time, the second leveling device 13 descends, and the lower bracket plate 131 flattens downward so that the steel strip of the second roll that continues to be output forms a buffer in the lower buffer frame 133, in order to compensate for fluctuations in the feeding speed and avoid interlayer misalignment caused by sudden changes in tension.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
