Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of silicon steel strip device, specifically relating to an auxiliary strip threading device. Background Technology
[0002] A silicon steel strip cross-cutting line is an automated shearing equipment specifically designed for processing silicon steel strip. It cuts coiled steel into sheets according to specific dimensions and stacks them, primarily used for the fixed-length shearing production of electrical steel sheets for transformers, motors, and other applications. With continuous advancements in industrial technology and increasing market demands, the automation requirements for silicon steel strip cross-cutting lines are also rising. Traditional silicon steel strip cross-cutting lines require manual threading between the uncoiling and feeding systems, which is time-consuming and labor-intensive. Existing auxiliary threading devices can replace manual labor for this task, but they suffer from drawbacks such as large footprint, complex installation, and high cost.
[0003] Chinese patent document CN203886949U discloses a steel strip auxiliary threading device. It uses a hydraulic cylinder to drive a second guide plate to rotate around the hinge point between the second guide plate and the first guide plate. When the steel strip needs to pass through the upper and lower guide rollers for the first time, the piston rod of the hydraulic cylinder is extended until the second guide plate is flush with the first guide plate. At this time, the second guide plate can play the role of assisting in guiding the steel strip, shortening the distance between the steel strip and the next process when the steel strip passes through the upper and lower guide rollers without auxiliary support. This allows for better control of the vertical jump of the steel strip head, making it easier for the steel strip to pass through for the first time. Its structure is different from that of this application and does not solve the shortcomings of existing auxiliary threading devices, such as large footprint, complex installation, and high cost.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0024] Example 1:
[0025] like Figure 1 and Figure 2 As shown, an auxiliary threading device includes a mounting frame 1, a feeding cart 2, a power system 4, and a control system. The feeding cart 2 is slidably connected to the upper part of the mounting frame 1, and the power system 4 is connected to the upper part of the mounting frame 1. The power output end of the power system 4 is connected to the feeding cart 2, and the control system is electrically connected to the feeding cart 2 and the power system 4 respectively.
[0026] Specifically, the mounting frame 1 is fixed on the open ground in the middle of the uncoiler, the feeding trolley 2 is located below the uncoiler head, the control system controls the feeding trolley 2 and the power system 4, the power system 4 provides power to the feeding trolley 2, and pushes the feeding trolley 2 to move back and forth along the feeding direction on the mounting frame 1; the control system is an existing device, which realizes the control of the feeding trolley 2 and the power system 4, and its structure will not be described in detail here.
[0027] Example 2:
[0028] Based on Example 1, such as Figure 3 and Figure 4 As shown, the feeding car 2 includes a drive unit 2.1, a belt conveyor 2.2, a frame 2.3, and a flap 2.4. The drive unit 2.1 is connected inside the frame 2.3. The power output end of the drive unit 2.1 is connected to the belt conveyor 2.2. The flap 2.4 is connected to the frame 2.3 and is located above the belt of the belt conveyor 2.2.
[0029] Specifically, when the cross-cutting line is not in operation or when it is running, the auxiliary threading device is in standby mode, and the feeding car 2 is in standby position, which does not affect the overall line processing. When the cross-cutting line needs to thread the material each time it is loaded, the auxiliary threading device is in operation: the flip plate 2.4 is raised, and the feeding car 2 moves forward according to the material feeding position of the uncoiler. After the material head contacts the flip plate 2.4, the flip plate 2.4 falls down, and the material head and the flip plate 2.4 fall together, so that the flip plate 2.4 falls onto the conveyor belt of the belt conveyor 2.2. The feeding car 2 cooperates with the uncoiler to feed the material head to the final position, which is convenient for the workers to thread the material.
[0030] Preferably, the feeding vehicle 2 further includes two drive units and a connecting rod 2.7. Both drive units are connected inside the frame 2.3. The drive device 2.1 is located between the two drive units. The power output end of one drive unit is connected to one end of the connecting rod 2.7, and the power output end of the other drive unit is connected to the other end of the connecting rod 2.7. The connecting rod 2.7 passes through the lower end of the flap 2.4.
[0031] Specifically, the power output ends of the two drive units drive the connecting rod 2.7 to rotate in the forward or reverse direction, which in turn drives the flap 2.4 to rotate, thus realizing the opening and closing action of the flap 2.4. Compared with some complex transmission mechanisms, it has a simple structure, occupies little space, is easy to lay out and install, and also reduces the overall design and manufacturing difficulty of the equipment, making installation and maintenance convenient.
[0032] Preferably, the drive unit includes a second drive device 2.5 and a first connecting rod 2.6. The second drive device 2.5 is connected to the frame 2.3, and the power output end of the second drive device 2.5 is connected to the second connecting rod 2.7 through the first connecting rod 2.6.
[0033] Specifically, when opening flap 2.4, drive device 2.5 pushes connecting rod 2.6 to move. Connecting rod 2.6 drives connecting rod 2.7 to move forward, rotating around connecting rod 2.7 as a fulcrum. This generates an upward force on flap 2.4, overcoming its own weight and other resistance, causing flap 2.4 to rotate upward around its rotation axis and open. When closing flap 2.4: drive device 2.5 pulls connecting rod 2.6 to move in the opposite direction, causing connecting rod 2.7 to rotate in the opposite direction, applying a downward force to flap 2.4. Under the combined force of gravity and connecting rod 2.7, flap 2.4 rotates downward around its rotation axis and closes. The entire process, through the linkage mechanism composed of connecting rods 2.6 and 2.7, converts the linear motion of drive device 2.5 into the rotation of flap 2.4, thus realizing the opening and closing actions of flap 2.4. The drive unit precisely and efficiently converts the linear telescopic motion of the drive device 2.5 into the rotation of the flap 2.4, meeting the specific requirements for the opening and closing action of the flap 2.4 in actual working conditions and realizing the flexible transformation of the mechanical motion form. This utility model utilizes the lever principle to amplify or rationally distribute the force output by the drive device 2.5, achieving a larger opening or closing torque of the flap 2.4 with a smaller push or pull force of the drive device 2.5. It can meet the action requirements of larger or heavier flaps 2.4 with a smaller drive device 2.5, reducing equipment costs and energy consumption.
[0034] Preferably, the driving device 2.5 is a cylinder.
[0035] Specifically, cylinders offer high power output, high motion precision, high reliability, strong adaptability, low maintenance costs, and fast response speed.
[0036] Preferably, the feeding cart 2 further includes a magnet 2.8, which is connected to the underside of the flip plate 2.4.
[0037] Specifically, the magnet 2.8 facilitates the stable adsorption of the material head onto the flip plate 2.4, and the material moves together with the flip plate 2.4, resulting in good stability.
[0038] Preferably, the feeding cart 2 further includes a detection switch 2.9, which is connected to the underside of the flip plate 2.4.
[0039] Specifically, the detection switch 2.9 facilitates the detection of the uncoiling machine's feeding position and sends the detection result to the control system. The control system then controls the power system 4 based on the detection result, thereby controlling the movement of the feeding carriage 2. This achieves a high degree of automation and accuracy. The detection switch 2.9 enables automated control, reducing the need for manual operation in this confined area.
[0040] Preferably, the flap 2.4 is provided with a through hole 2.41 at a position directly above the belt of the conveyor belt 2.2.
[0041] Specifically, the through hole 2.41 helps to reduce the weight of the flap 2.4.
[0042] Preferably, the detection switch 2.9 is a photoelectric switch, and the photoelectric transmitter and receiver of the photoelectric switch are located at the through hole 2.41.
[0043] Specifically, the 2.41 through hole facilitates photoelectric switch detection, which is unaffected by magnetic fields and oscillations, resulting in high detection accuracy.
[0044] Preferably, the drive device 2.1 is a DC motor.
[0045] Specifically, DC motors have excellent speed regulation performance, fast dynamic response, high efficiency, and simple structure and maintenance.
[0046] Preferably, the power system 4 is an electric cylinder.
[0047] Specifically, compared to pneumatic or hydraulic systems, electric cylinders only consume electrical energy when working, with extremely low energy consumption when in standby mode. They also have high energy conversion efficiency, high control precision, simple structure, fewer moving parts, and only require periodic lubrication and inspection, resulting in a longer maintenance cycle than pneumatic or hydraulic systems.
[0048] Example 3:
[0049] Based on Embodiment 2, the auxiliary threading device further includes a material support roller 3, which is connected to the front side of the frame 2.3, and one end of the material support roller 3 is connected to the feeding vehicle 2.
[0050] Specifically, one end of the material support reel 3 is connected to the feeding trolley 2. During the movement of the feeding trolley 2, it assists in supporting the material and prevents the unwinding machine from releasing the material too quickly, causing the sheet material to contact the ground and resulting in unnecessary bending and other losses.
[0051] The working principle of this utility is as follows:
[0052] When the cross-cutting line is not in operation or when it is running, the auxiliary threading device is in standby mode, and the feeding trolley 2 is in standby position, which does not affect the overall line processing. When the cross-cutting line needs to thread the material each time it is loaded, the auxiliary threading device is in operation: the flip plate 2.4 is raised, the detection switch 2.9 detects the uncoiling position of the uncoiling machine, and the feeding trolley 2 moves forward according to the uncoiling position. After the material head contacts the flip plate 2.4, the flip plate 2.4 falls down. The material head falls together with the flip plate 2.4 under the action of the magnet 2.8, so that the flip plate 2.4 falls on the conveyor belt of the belt conveyor 2.2. The feeding trolley 2 cooperates with the uncoiling machine to feed the material head to the final position, which is convenient for the workers to thread the material. One end of the drum of the material support roll 3 is connected to the feeding trolley 2. During the movement of the feeding trolley 2, it assists in supporting the material and prevents the uncoiling machine from feeding the material too fast, which would cause the sheet material to contact the ground and cause unnecessary bending and other losses.
