A positioning device for flat iron cutting

Abstract

This utility model discloses a positioning device for cutting flat iron, including a fixed platform, a lifting frame mounted on the upper end of the fixed platform, a lifting platform mounted on the upper end of the lifting frame, multiple limiting rollers mounted on both sides of the upper surface of the lifting platform, a first positioning platform mounted on one side of the upper surface of the fixed platform, a second positioning platform mounted on one side of the upper surface of the lifting platform, a movable frame mounted on the fixed platform, and a positioning block that can move up and down mounted on the fixed platform. The beneficial effects of this utility model are that after the flat iron is cut, the movable frame drives the lifting platform to move laterally, which in turn allows the lifting platform to move the flat iron, causing the flat iron to move to one side of the first positioning platform. Then, the lifting platform moves downwards and then in the opposite direction, allowing the flat iron to be neatly arranged under the action of the first and second positioning platforms. Furthermore, because the cut flat iron moves downwards, it prevents the rear flat iron from colliding with the front flat iron, reducing safety hazards.

Description

Technical Field

[0001] This utility model relates to the technical field of flat iron cutting equipment, and more specifically, to a positioning device for cutting flat iron. Background Technology

[0002] To facilitate transportation, flat iron is stored in coils after processing. After being moved to the processing workshop, it needs to be cut into long strips and multiple strips of flat iron are bundled and packaged.

[0003] In existing technology, when cutting flat iron to a fixed length, multiple flat irons are typically passed through the cutting machine and then placed onto a lifting platform. After a set of flat irons is cut, the height of one layer of flat irons is moved below the lifting platform, allowing the second layer of flat irons to fall on top of the first layer, thus enabling the stacking of multiple layers of flat irons. However, this method has some problems. One end of the cut flat iron may rest on the cutting machine, and sometimes, due to friction, this end cannot fall onto the lifting platform. Consequently, when the subsequent flat irons continue to be fed, they are prone to collision, posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to solve the problem of flat iron being prone to collisions, and to design a positioning device for cutting flat iron.

[0005] To achieve the above objectives, the technical solution of this utility model is a positioning device for cutting flat iron, comprising a fixed platform, a lifting frame installed on the upper end of the fixed platform, a lifting platform installed on the upper end of the lifting frame, multiple limiting rollers installed on both sides of the upper surface of the lifting platform, a first positioning platform installed on one side of the upper surface of the fixed platform, a second positioning platform installed on one side of the upper surface of the lifting platform, a movable frame installed on the fixed platform, the movable frame being able to drive the lifting platform to move, and a positioning block that can move up and down installed on the fixed platform, the movable frame being able to drive the positioning block to move up and down.

[0006] Furthermore, the lifting frame includes a plurality of first electric telescopic rods mounted on the upper surface of the fixed platform. The telescopic ends of the first electric telescopic rods are equipped with guide blocks. Guide grooves are opened on both sides of the lower surface of the lifting platform. The guide blocks are located in the guide grooves. Guide wheels are mounted on the upper surface of the guide blocks.

[0007] Furthermore, guide cylinders are installed at both ends of the positioning block, and guide rods are provided inside the guide cylinders. The lower end of the guide rod is installed on a fixed platform, and a fixed plate is installed at the upper end of the guide rod. The fixed plate and the positioning block are connected by a compression spring.

[0008] Furthermore, the movable frame includes a second electric telescopic rod installed on both sides of the upper surface of the fixed platform. Connecting blocks are installed at both ends of one side surface of the lifting platform. The connecting blocks have elongated holes. A tension rod is installed at the telescopic end of the second electric telescopic rod. The tension rod passes through the elongated hole. Stop blocks are installed at both ends of the tension rod. The stop blocks at both ends of the tension rod are located on both sides of the connecting block. Lifting wheels are installed on both sides of the lower surface of the positioning block. A trapezoidal block is installed at the upper end of the tension rod. The trapezoidal block can pass under the lifting wheel and push the lifting wheel upward.

[0009] Furthermore, a support wheel is installed at the lower end of the trapezoidal block.

[0010] The beneficial effects of this utility model are as follows: After the flat iron is cut, the lifting platform is moved laterally by the moving frame, which in turn moves the flat iron and causes it to move to one side of the first positioning platform. Then the lifting platform is moved downward and then in the opposite direction, so that the flat iron is arranged neatly under the action of the first positioning platform and the second positioning platform. Furthermore, since the cut flat iron moves downward, it can prevent the rear flat iron from colliding with the front flat iron and reduce safety hazards. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] This utility model provides, for example Figure 1-5 The positioning device shown includes a fixed platform 1, a lifting frame 2 mounted on the upper end of the fixed platform 1, a lifting platform 3 mounted on the upper end of the lifting frame 2, multiple limiting rollers 4 mounted on both sides of the upper surface of the lifting platform 3, a first positioning platform 5 mounted on one side of the upper surface of the fixed platform 1, a second positioning platform 6 mounted on one side of the upper surface of the lifting platform 3, a movable frame 7 mounted on the fixed platform 1, the movable frame 7 can drive the lifting platform 3 to move, and a positioning block 8 that can move up and down is mounted on the fixed platform 1, the movable frame 7 can drive the positioning block 8 to move up and down.

[0015] The positioning process of this device for flat iron is as follows: Multiple flat irons are moved by the drive device and pass under the cutting device, allowing the flat irons to move above the lifting platform 3. The limiting roller 4 limits both ends of the flat iron. When one end of the flat iron abuts against the positioning block 8, the drive device is turned off, and then the cutting device cuts the flat iron. After cutting, the shorter end of the flat iron falls onto the first positioning platform 5, and the longer end falls onto the lifting platform 3. Then, the moving frame 7 drives the positioning block 8 upwards, causing the lifting platform 3 to move away from the first positioning block 5. When the platform 5 moves to one side, the friction between the lifting platform 3 and the flat iron is greater than that between the first positioning platform 5 and the flat iron. As the lifting platform 3 moves, it can move the flat iron to one side of the first positioning platform 5. Then, the lifting frame 2 drives the lifting platform 3 to move downward, and the flat iron moves downward. Then, the moving frame 7 moves the lifting platform 3 closer to the first positioning platform 5, so that one side surface of the lifting platform 3 and the flat iron are pressed against the first positioning platform 5, and the flat iron can be placed in it. The second positioning platform 6 can limit the flat iron.

[0016] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 4 The lifting frame 2 includes multiple first electric telescopic rods 9 installed on the upper surface of the fixed platform 1. The telescopic ends of the first electric telescopic rods 9 are equipped with guide blocks 10. Guide grooves 11 are opened on both sides of the lower surface of the lifting platform 3. The guide blocks 10 are located in the guide grooves 11. Guide wheels 12 are installed on the upper surface of the guide blocks 10. When the first electric telescopic rods 9 are activated to extend or retract, the lifting platform 3 can be moved up and down through the guide blocks 10 and the guide wheels 12. The guide blocks 10 and the guide grooves 11 can ensure the direction of the lifting platform 3 when it moves laterally. The guide wheels 12 can reduce the friction force when the lifting platform 3 moves laterally.

[0017] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The positioning block 8 is equipped with guide cylinders 13 at both ends, and guide rods 14 are provided inside the guide cylinders 13. The lower end of the guide rods 14 is installed on the fixed platform 1, and a fixed plate 15 is installed on the upper end of the guide rods 14. The fixed plate 15 and the positioning block 8 are connected by a compression spring 16. Under normal conditions, the positioning block 8 can be pushed downward by the compression spring 16, so that the lower end of the positioning block 8 presses against the upper surface of the lifting platform 3 or the upper end of the flat iron placed on the lifting platform 3, thereby positioning the subsequent flat iron. When the moving frame 7 pushes the positioning block 8 upward, it can compress the compression spring 16. The guide rods 14 and the guide cylinders 13 can ensure the moving direction of the positioning block 8.

[0018] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Included with instruction manual Figure 5The movable frame 7 includes a second electric telescopic rod 17 installed on both sides of the upper surface of the fixed platform 1. Connecting blocks 18 are installed at both ends of one side surface of the lifting platform 3. The connecting blocks 18 have elongated holes 19. The telescopic end of the second electric telescopic rod 17 is equipped with a tension rod 20. The tension rod 20 passes through the elongated hole 19. Stop blocks 21 are installed at both ends of the tension rod 20. The stop blocks 21 at both ends of the tension rod 20 are located on both sides of the connecting block 18. Lifting wheels 22 are installed on both sides of the lower surface of the positioning block 8. A trapezoidal block 23 is installed at the upper end of the tension rod 20. The trapezoidal block 23 can pass under the lifting wheel 22 and push the lifting wheel 22 upward.

[0019] The process of the movable frame 7 moving the lifting platform 3 and the positioning block 8 is as follows: The second electric telescopic rod 17 is activated to shorten, which in turn moves the tension rod 21. At this time, the stop block 21 on the side of the tension rod 21 closest to the trapezoidal block 23 has not yet contacted the connecting block 18, thus preventing the connecting block 18 and the lifting platform 3 from moving laterally. However, it can move the trapezoidal block 23. Under the action of the inclined surface of the trapezoidal block 23, the lifting wheel 22 can be pushed upwards, causing the positioning block 8 to move upwards, thus preventing the positioning block 8 from blocking the flat iron. When the plane position of the trapezoidal block 23... After moving below the lifting wheel 22, the positioning block 8 stops moving. When the stop block 21 on the side of the tension rod 21 near the trapezoidal block 23 moves to the side of the connecting block 18, the connecting block 18 and the lifting platform 3 can move. When the lifting platform 3 needs to return to its original position, the second electric telescopic rod 17 is activated to extend, which allows the tension rod 20 to move. When the stop block 21 on the side of the tension rod 20 near the second electric telescopic rod 17 contacts the connecting block 18, the connecting block 18 and the lifting platform 3 can be pushed back to their original positions. The elongated hole 19 can avoid the tension rod 20 when the lifting platform 3 moves up and down.

[0020] Refer to the instruction manual appendix Figure 1 The trapezoidal block 23 is equipped with a support wheel 24 at its lower end, which can support the trapezoidal block 23 and prevent it from falling.
