A safe feeding device

Abstract

This utility model discloses a safe feeding device, including a base plate. Two sets of support frames and a set of support seats are arranged on the top surface of the base plate, with each set of support frames and support seats consisting of two units. A drive roller assembly is fixed to the lower inner side of each support frame, and a vertically movable pressing roller assembly is arranged above the inner side of each support frame. The pressing roller assembly presses the steel strip onto the drive roller assembly and conveys the steel strip. Steel strip support assemblies are arranged between the support frames and the movable bearing seat. The pressing roller assembly presses the steel strip onto the drive roller assembly, thus assisting in the feeding of the steel strip and ensuring stable conveying. Therefore, after aligning the steel strip with the roller and inserting it into the cylinder clamp, the user can release their hand, eliminating the need to manually hold the steel strip. This improves the efficiency of line changing and material changing, and also ensures employee safety.

Technical Field

[0001] This utility model relates to the field of steel strip processing, and in particular to a safe feeding device. Background Technology

[0002] Steel strip roll forming is a process that uses multiple passes of continuous plastic forming to gradually deform metal strips or sheets into the desired cross-sectional shape. During roll forming, the metal material undergoes various deformations, including longitudinal stretching, shearing, transverse bending, and out-of-plane bending. Transverse bending is the primary effective deformation, used to shape the sheet into the target cross-section.

The current manual threading method has low efficiency for line changing and material changing, and also poses certain safety risks. Utility Model Content

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0017] Example: Please refer to Figures 1-4 As shown, this utility model provides a safe feeding device, including a base plate 1. The top surface of the base plate 1 is provided with two sets of support frames 2 and a set of support seats 15. The two sets of support frames 2 are respectively located at the edge of the top surface of the base plate 1, and the support seats 15 are located in the middle of the two sets of support frames 2. Each set of support frames 2 has a fixed bearing seat 3 fixed inside at the bottom. The support seats 15 also has a fixed bearing seat 3 fixed inside. The multiple fixed bearing seats 3 are at the same height, and the fixed bearing seats 3 are provided with bearings inside. They are connected to the drive roller 11 through the bearings. One end of the drive roller 11 shaft passes through a bearing and extends outward and is connected to a connecting part 22. The connecting part 22 can be a coupling. The reducer is connected through the coupling, and then a motor is connected for driving. like Figures 1-4As shown, each of the four support frames 2 is equipped with a movable bearing seat 5. The tops of two movable bearing seats 5 on the same side are connected by a connecting plate 6, and a driven pressure roller 12 is connected between the two movable bearing seats 5 by a bearing. A top block 8 is fixed to the top of the support frame 2, and symmetrical guide rods 7 are fixed to the top surface of the connecting plate 6. The guide rods 7 pass through the top block 8 and extend upward. Through the action of the guide rods 7 and the top block 8, the up and down movement of the driven pressure roller 12 is relatively stable. A supporting top plate 9 is provided between the top blocks 8. A hydraulic cylinder 10 is fixed at the center of the top surface of the supporting top plate 9. The telescopic end of the hydraulic cylinder 10 extends downward and is fixedly connected to the connecting plate 6. The height of the driven pressure roller 12 is changed by the telescopic movement of the hydraulic cylinder 10.

[0018] like Figures 1-3 As shown, a support plate 14 is provided between the support frame 2 and the support base 15. The top surface of the support plate 14 is provided with symmetrical rectangular grooves for accommodating the support roller 13. The support roller 13 is connected to the support plate 14 by a rotating shaft, so that the support roller 13 can rotate and the steel strip is supported by the support roller 13 and the support plate 14. like Figures 1-4 As shown, a fixed side plate 16 is fixed to one side of the support frame 2 facing outwards. The fixed side plate 16 spans across the sides of the two support frames 2. A support cross plate 18 is fixed to the other side of the fixed side plate 16. Two symmetrical fixing blocks 17 are fixed to the top surface of the support cross plate 18. The sides of the fixing blocks 17 are connected to the fixed side plate 16 by screws. A bidirectional lead screw 21 passes between the two fixing blocks 17. One end of the bidirectional lead screw 21 passes through the fixing block 17 and extends a certain distance before being connected to a handle 4. A movable block 20 is connected to the outer thread. The bottom surface of the movable block 20 contacts the top surface of the supporting horizontal plate 18. The top surface of the movable block 20 is connected to a limiting roller 19 through a rotating shaft. Two guide grooves 23 are symmetrically opened on the top surface of the supporting horizontal plate 18. A limiting guide block 24 inserted into the guide groove 23 is fixed on the bottom surface of the movable block 20. The width of the limiting guide block 24 is the same as the width of the guide groove 23. The cooperation between the guide groove 23 and the limiting guide block 24 further ensures the stability of the movement of the movable block 20. Both the drive roller 11 and the driven pressure roller 12 are covered with anti-slip rubber to prevent the steel strip from slipping and reduce wear. The drive roller 11 between the support seats 15 does not require a drive source. Figure 3 As shown, the middle position of the limiting roller 19 is slightly lower than the highest position of the drive roller 11.

[0019] Specific working principle: The steel strip is kept as parallel as possible to the side of the base plate 1. It passes between the two limiting rollers 19, and then between the drive roller 11 and the driven pressure roller 12. The hydraulic cylinder 10 on this side is activated, pushing the driven pressure roller 12 downwards to press the steel strip tightly between the drive roller 11 and the driven pressure roller 12. The drive unit is then activated, causing the drive roller 11 to rotate via the connecting part 22, thus conveying the steel strip. To ensure stable steel strip conveying, the extension length of the hydraulic cylinder 10 can be controlled by a microcontroller according to the steel strip thickness. This ensures smooth steel strip conveying without causing wear to the equipment and steel strip due to excessive pressure between the drive roller 11 and the driven pressure roller 12. After passing the support frame 2 on one side, the steel strip will fall onto the support plate 14 due to gravity at the end. As the steel strip is conveyed, it passes through the support rollers. The guide rollers 13 and 14 will fall on the drive roller 11 of the support base 15. After being conveyed to another set of support frames 2 through another set of support rollers 13 and support plates 14, the driven roller 12 at the feed position has a downward pressure and drive source. Therefore, the driven roller 12 at this position can leave a certain distance from the drive roller 11. The drive roller 11 at the feed position drives the conveying of the steel strip. The gap limits the steel strip and does not need to be driven again. When the steel strip passes through the structure at the support frame 2 at the discharge position, the hydraulic cylinder 10 at the discharge position can be activated to move the hydraulic cylinder 10 downward to press the steel strip, thereby ensuring the stability of the steel strip conveying. In order to ensure the stability of the conveying, the drive source at the feed position can be turned off and the drive source at the discharge position can be activated, so that the steel strip can provide stable tension when it is processed after the steel strip is discharged.
