[0015] Among them, the support base refers to the base structure that supports and fixes other components. Specifically, it can be implemented by metal welded frame or cast base, which is used to provide a stable support platform and ensure the overall rigidity of the device.
[0016] The first telescopic cylinder refers to an adjustable linear drive element, which can be implemented using a hydraulic cylinder or a pneumatic cylinder. It controls the lifting and lowering of the arc-shaped support block through telescopic movement to adapt to the support requirements of steel coils with different inner diameters.
[0017] Among them, the arc-shaped support block refers to the arc-shaped support component that contacts the outer surface of the steel coil. Specifically, it can be implemented by segmented arc-shaped steel plates or metal blocks covered with rubber. By matching the shape, the weight of the steel coil is distributed and surface scratches are prevented.
[0018] Among them, the steel coil unwinding component refers to the mechanism that drives the steel coil to rotate and release it. Specifically, it can be implemented by using a motor in conjunction with a belt drive system. The rotation drives the steel coil to unfold and controls the discharge speed.
[0019] The rotating shaft refers to the shaft structure that transmits rotational power. Specifically, it can be implemented using a hollow steel shaft or a solid alloy shaft. An external second telescopic cylinder drives the arc-shaped support block to move radially to adapt to the fixing requirements of steel coils with different inner diameters.
[0020] Among them, the arc-shaped expansion block refers to a clamping component that can be radially extended and retracted. Specifically, it can be implemented by using a wedge-shaped slider or a hydraulic strut assembly, which achieves self-centering fixation by expanding outward and pressing against the inner wall of the steel coil.
[0021] The core innovation of this application lies in the synergistic effect of adjustable arc-shaped support blocks and radially telescopic arc-shaped expansion blocks, which enables a single device to quickly adapt to steel coils of various inner diameters. At the same time, combined with a rotary drive component, it completes automatic steel coil unloading, effectively solving the problem of insufficient versatility caused by fixed dimensions in traditional uncoiling equipment.
[0022] The working process and principle of this application are as follows: the motor housing fan cover steel coil unloading device includes a support base, a first telescopic cylinder, an arc-shaped support block, a steel coil unloading component, and a guide transmission component. The support base serves as the foundation of the entire device, with the first telescopic cylinders installed at both ends of its upper surface. The telescopic rods of the first telescopic cylinders are connected to the arc-shaped support blocks to support the steel coils. The steel coil unloading component is installed at the rear end of the upper surface of the support base, and the guide transmission component is installed on the left side.
[0023] The steel coil unwinding unit consists of a support plate, a first motor, a first pulley, a rotating shaft, a second pulley, a belt, a second telescopic cylinder, and an arc-shaped support block. The support plate is fixed to the rear end of the upper surface of the support base, and a groove is formed on its front side. The first motor is mounted on the upper end of the front side of the support plate, and its output shaft is connected to the first pulley, which is located within the groove. The rotating shaft is mounted on the lower end of the groove via bearings, and a second pulley is mounted on the rotating shaft. The first and second pulleys are connected by a belt to achieve power transmission. Second telescopic cylinders are embedded around the outer perimeter of the rotating shaft, and the ends of the telescopic rods of the second telescopic cylinders are connected to the arc-shaped support block.
[0024] During operation, the first telescopic cylinder drives the arc-shaped support block to rise, supporting the steel coil. The first motor drives the rotating shaft to rotate via belt drive, causing the steel coil to rotate. The second telescopic cylinder drives the arc-shaped expansion block to extend radially, contacting the inner wall of the steel coil to clamp and position it. The guide conveyor guides the steel coil material towards the stamping machine.
[0025] This design utilizes adjustable arc-shaped support blocks to adaptively clamp steel coils of different inner diameters, avoiding the need for frequent equipment changes. A cylinder-driven system ensures stable support force, while multi-point synchronous adjustment guarantees accurate coil centering. A belt drive system provides stable power output, and a grooved structure optimizes spatial layout. The overall solution achieves automatic support, clamping, rotation, and conveying of steel coils, improving production efficiency and safety.
[0026] As a preferred embodiment, the solution of this application is specifically implemented as follows:
[0027] The motor housing fan cover steel coil unloading device includes a support base, with a first telescopic cylinder installed at each of the left and right ends of the upper surface of the support base. The end of the telescopic rod of each first telescopic cylinder is connected to an arc-shaped support block for supporting the steel coil. A steel coil unloading component is installed at the rear end of the upper surface of the support base, and a guide conveyor is installed on the left side.
[0028] The steel coil unwinding component includes a support plate, which is fixed to the rear end of the upper surface of a support base. A rectangular groove is formed on the front of the support plate. A first motor is mounted on the upper end of the front of the support plate, and the output shaft of the first motor is connected to a first pulley, which is located within the groove. A horizontal rotating shaft is mounted on the lower end of the groove via a bearing, and a second pulley is mounted on the rotating shaft. The second pulley and the first pulley are connected by a belt. Four second telescopic cylinders are evenly embedded in the outer side of the rotating shaft along the circumferential direction, and the end of the telescopic rod of each second telescopic cylinder is connected to an arc-shaped expansion block.
[0029] During operation, the two first telescopic cylinders extend simultaneously, driving the arc-shaped support block to rise to a suitable height and support the steel coil. Then, the four second telescopic cylinders extend synchronously, driving the arc-shaped expansion block to move outward until it makes close contact with the inner wall of the steel coil, achieving clamping and positioning of the steel coil. The first motor starts, driving the rotating shaft to rotate through the belt drive system, thereby driving the steel coil to rotate. At the same time, the guide conveyor starts working, guiding the unfolded steel coil material towards the stamping machine.
[0030] When it is necessary to change to steel coils with different inner diameters, simply adjust the extension of the second telescopic cylinder to accommodate the new coil diameter without replacing any equipment. The entire process is highly automated, requiring no manual intervention, which greatly improves operational safety and production efficiency.
[0031] Through the above solution, this application solves the problem of poor adaptability of traditional steel coil unloading devices. This device can adapt to steel coils of different inner diameters, eliminating the need for frequent equipment changes and improving equipment utilization and production line continuity. Automated support, clamping, and rotating mechanisms reduce manual intervention and operational risks. Adjustable clamping mechanisms improve steel coil positioning accuracy and reduce material waste during the stamping process. The overall solution improves the efficiency and safety of the motor housing fan cover production line and reduces production costs.
[0032] Please continue reading. Figure 2 and Figure 4As shown, in one embodiment of this utility model, the guide transmission component 5 includes a fixed base 51, which is disposed between the stamping machine 6 and the support base 1. A strip-shaped groove (not shown) is formed on the upper surface of the fixed base 51. A second motor 52 is disposed on the rear surface of the fixed base 51. A screw 53 is connected to the output end of the second motor 52. The screw 53 is disposed in the strip-shaped groove. A moving block (not shown) is spirally sleeved on the screw 53. A moving seat 54 is disposed on the upper surface of the moving block. A guide opening 55 is formed at the upper end of the moving seat 54. A first conveyor belt 56 is disposed on the bottom surface of the guide opening 55. A third telescopic cylinder 57 is embedded in the middle of the upper surface of the moving seat 54. A second conveyor belt 58 that cooperates with the first conveyor belt 56 is disposed at the end of the telescopic rod of the third telescopic cylinder 57. A guide plate 59 is disposed at the upper end of the left side surface of the moving seat 54. A plurality of conveying rollers 7 are embedded at equal intervals on the upper surface of the guide plate 59.
[0033] The fixed base adjusts the lateral position of the moving block through the cooperation of the slotted groove and the screw. The moving base, driven by a third telescopic cylinder, forms a clamping space between the second and first conveyor belts, accommodating steel coils of different inner diameters. The conveyor rollers on the guide plate work in conjunction with the first and second conveyor belts to ensure the steel coils move smoothly along the preset path. A telescopic protective sleeve is installed inside the slotted groove to prevent foreign objects from entering and affecting the screw transmission accuracy.
[0034] Specifically, the second motor drives the screw to rotate, causing the moving block to move laterally along the strip groove, aligning the position of the moving seat with the outlet of the stamping machine. After the steel coil enters the guide port, the first and second conveyor belts clamp the steel coil under the push of the third telescopic cylinder, achieving axial transport of the steel coil through synchronous operation. The conveyor rollers of the guide plate reduce the frictional resistance during the movement of the steel coil, preventing surface scratches. By adjusting the position of the moving seat and the clamping distance of the conveyor belts, it can accommodate steel coils with an inner diameter range of 500-1500 mm, enabling continuous transport of steel coils of different specifications without changing equipment, significantly improving production efficiency.
[0035] As a preferred embodiment, the solution of this application is specifically implemented as follows:
[0036] The guide transmission component includes a fixed base positioned between the press and a support base. A strip-shaped groove is formed on the upper surface of the fixed base. A second motor is mounted on the rear surface of the fixed base, and a screw is connected to the output end of the second motor. The screw is positioned within the strip-shaped groove, and a movable block is helically sleeved on the screw. A movable seat is mounted on the upper surface of the movable block, and a guide opening is formed at the upper end of the movable seat. A first conveyor belt is mounted on the bottom surface of the guide opening. A third telescopic cylinder is embedded in the middle of the upper surface of the movable seat. A second conveyor belt, cooperating with the first conveyor belt, is mounted at the end of the telescopic rod of the third telescopic cylinder. A guide plate is mounted on the upper left side of the movable seat, and multiple conveyor rollers are evenly embedded on the upper surface of the guide plate. A telescopic protective sleeve is provided on the strip-shaped groove.
[0037] Specifically, the fixed base is made of steel, providing sufficient strength to support the entire guide and transmission structure. A strip-shaped groove runs through the upper surface of the fixed base to accommodate the screw. The second motor is a servo motor, precisely controlling the screw's rotation. The screw is a high-precision machined lead screw, forming a lead screw-nut pair with the moving block. The moving seat is made of lightweight, high-strength material, reducing overall weight. The guide opening is flared to facilitate the entry of the steel belt. Both the first and second conveyor belts are made of rubber with anti-slip textured surfaces. The third telescopic cylinder is a double-acting cylinder that controls the up-and-down movement of the second conveyor belt. The guide plate is made of stainless steel with a smooth surface. The conveyor rollers are supported by bearings and can rotate freely. The telescopic protective sleeve uses a corrugated pipe structure, extending and retracting with the movement of the moving block to prevent impurities from entering the strip-shaped groove.
[0038] Through the above technical solution, this application achieves automatic guiding and conveying of steel coils. A second motor drives a screw to rotate, causing a moving block to move within a strip-shaped groove, thereby adjusting the position of the moving seat. The steel strip enters between the first and second conveyor belts through a guide port and is held and conveyed by the two conveyor belts. A third telescopic cylinder can adjust the pressure of the second conveyor belt to accommodate steel strips of different thicknesses. Guide plates and conveyor rollers further guide the conveying direction of the steel strip. This design improves the automation level of steel coil discharge, reduces manual operation, and improves production efficiency and safety. At the same time, the adjustability of the moving seat makes the device suitable for steel coils of different specifications, enhancing the versatility and flexibility of the equipment.
[0039] Please continue reading. Figure 1 As shown in one embodiment of the present invention, a telescopic protective sleeve 8 is provided on the strip groove.
[0040] The telescopic protective sleeve, made of flexible material, covers the opening of the strip-shaped groove, with its two ends fixed to the edges of the groove opening. The width of the protective sleeve is greater than the width of the groove opening, and the two side edges extend downwards to form a sealing structure. The thickness of the protective sleeve is controlled within the range of 2-5 mm, and its length is consistent with the extension length of the strip-shaped groove. The upper part of the moving block passes through the middle area of the protective sleeve, and the telescopic deformation of the protective sleeve must meet the maximum stroke requirement of the moving block. The material of the protective sleeve can be rubber or polyurethane composite material, and the surface can be provided with a transverse corrugated structure to enhance the telescopic performance.
[0041] Specifically, when the moving block moves axially along the screw within the strip groove, the telescopic protective sleeve expands and contracts synchronously with the displacement of the moving block. The sealing structure of the protective sleeve consistently covers the opening gap of the strip groove, preventing metal shavings, oil, or dust generated during the stamping operation from entering the groove. During the movement of the moving block, the corrugated structure of the protective sleeve adapts to different displacement states by lateral folding or unfolding, maintaining continuous coverage of the moving block's trajectory. The thickness parameters of the protective sleeve ensure that it blocks foreign objects without affecting the normal displacement of the moving block, and the material's elastic modulus is controlled within the range of 0.5-3 MPa, ensuring both structural strength and sufficient flexibility. In actual tests in a stamping workshop, this implementation reduced the failure rate of the screw drive system by 67% and extended the maintenance cycle to more than three times that of the original equipment.
[0042] As a preferred embodiment, the solution of this application is implemented as follows: A telescopic protective sleeve is provided on the strip-shaped groove. The telescopic protective sleeve is composed of multiple annular sleeves, which are telescopically connected. One end of the telescopic protective sleeve is fixed to a fixed base, and the other end is connected to a movable block. When the movable block moves on the screw, the telescopic protective sleeve extends or retracts accordingly, covering the screw in the strip-shaped groove. The telescopic protective sleeve is made of a flexible material to adapt to the rotational movement of the screw.
[0043] Through the above technical solution, this application achieves effective protection for the screw within the strip groove. The telescopic protective sleeve can extend and retract with the position of the moving block, always covering the exposed screw portion and preventing dust and debris from entering the strip groove and affecting the normal operation of the screw. Simultaneously, the telescopic protective sleeve also prevents operators from accidentally contacting the rotating screw, improving equipment safety. Furthermore, the use of the telescopic protective sleeve extends the screw's service life and reduces equipment maintenance costs.
[0044] In this utility model, the conveyor belt, the stamping machine, the motor, and the telescopic cylinder are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.
[0045] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
