Description

[0002] A flying shear is a device used to cut moving materials. It can quickly and accurately complete the cutting action according to a set length or time interval during the continuous movement of the material. Flying shears are mainly used in the steel, paper and plastic film industries. They are key equipment for achieving fixed-length cutting in the production line. The cutter height adjustment mechanism can adjust the position of the cutter, which directly affects the quality of the cut material.

[0003] The blade height adjustment mechanism plays a crucial role in the operation of the flying shear. By precisely controlling the blade height, it ensures the accuracy of the material cutting length and the cutting quality, enabling the flying shear to achieve high-quality cutting results when processing different materials. At the same time, it allows the flying shear to quickly adapt to different production tasks, meeting various product specification requirements by adjusting the blade height, thereby improving production efficiency and product diversity.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 ,and Figure 2This utility model provides an embodiment of a flying shear cutter height adjustment mechanism, comprising a base plate 1, two pressure plates 15, and two flying shear cutters 25. The pressure plates 15 fix the object to be cut, facilitating the cutting by the flying shear cutters 25 and effectively preventing errors during cutting, thus improving cutting accuracy. A protective shell 2 is fixedly connected to the top of the base plate 1. Limiting sleeves 3 are fixedly connected to the left and right sides of the top of the base plate 1. Support plates 4 are fixedly connected to the left and right sides of the top of the base plate 1. Multiple bolts 24 are threaded onto the outer walls of both support plates 4, penetrating the interior of the support plates 4 and threaded onto the top of the base plate 1. By installing multiple bolts 24 on the support plates 4, the support plates 4 can be firmly fixed to the base plate 1. The bottom of plate 1 improves the stability of the equipment and prevents the support plate 4 from slipping off the base plate 1 during operation, thus avoiding safety accidents. A connecting rod 5 runs through the middle of the two support plates 4. Two gears 6 are fixedly connected to the outer wall of the connecting rod 5. A motor 7 is fixedly connected to the left end of the connecting rod 5. The two gears 6 are connected together through the connecting rod 5, so that the rotation of the motor 7 drives the two gears 6 to rotate synchronously. The connecting rod 5 runs through the middle of the two support plates 4, so that the support plates 4 can support the gears 6 and the connecting rod 5. The inside of the two limiting sleeves 3 is slidably connected with toothed plates 8. The outer wall of the limiting sleeves 3 is provided with a receiving groove, so that the gears 6 mesh with the toothed plates 8 in the receiving groove, so that the rotation of the gears 6... The kinetic energy drives the toothed plate 8 to slide up and down within the limiting sleeve 1 3. Multiple receiving grooves 9 are provided on the front side of each toothed plate 8. Two limiting sleeves 2 10 are fixedly connected to the front side of the inner wall of the protective shell 2. Sliding plates 14 are slidably connected to the inner walls of each limiting sleeve 2 10. Return springs 13 are installed inside each limiting sleeve 2 10. Pull handles 12 are fixedly connected to the inner walls of each sliding plate 14. Each pull handle 12 consists of two parts: a front part is an inverted frustum shape, and a rear part is cylindrical. Pressure sensors 11 are fixedly connected to the rear ends of each pull handle 12. Multiple rollers 16 are rotatably connected to adjacent sides of each of the two pressure plates 15. A support platform 17 is fixedly connected to the top of the protective shell 2, and the top of the top pressure plate 15 is fixedly connected to the support platform. Inside 17, the bottom of the bottom pressure plate 15 is fixedly connected to the top of the two toothed plates 8. The diameter of the receiving groove 9 is the same as the diameter of the rear end of the pull handle 12. The receiving groove 9 is used to receive the rear part of the pull handle 12. When the height needs to be adjusted, the pull handle 12 is pulled away from the receiving groove 9. At this time, the gear 6 drives the toothed plates 8 to move. Since the limiting sleeve 10 is fixedly connected to the inner wall of the protective shell 2, the pull handle 12 and the sliding plate 14 are fixedly connected. The front end of the return spring 13 is fixedly connected to the inner wall of the limiting sleeve 10, and the rear end of the return spring 13 is fixedly connected to the front side of the sliding plate 14. Therefore, pulling the pull handle 12 can drive the sliding plate 14 to squeeze the return spring 13, causing it to deform. When the height adjustment is completed, the pull handle 12 is released.Due to the resetting action of the return spring 13, the pull handle 12 moves backward and enters the receiving groove 9. At this time, the pressure sensor 11 at the rear end of the pull handle 12 senses the pressure and controls the motor 7 to stop running. Through the limiting action of the pull handle 12 and the receiving groove 9, the toothed plate 8 is fixed, thereby achieving the effect of height adjustment. A disassembly mechanism 18 is provided on the left side of each of the two pressure plates 15. The disassembly mechanism 18 is used to replace the flying shear blade 25.

[0033] Reference Figure 3 , Figure 4 and Figure 5 The disassembly mechanism 18 includes a drive assembly 1801. The right side of the drive assembly 1801 is fixedly connected to the left side of the pressure plate 15. The drive assembly 1801 is located on the right side of the flying shear blade 25. The drive assembly 1801 is used to control the cutting direction of the flying shear blade 25. A limiting groove 1802 is provided inside the drive assembly 1801. A fixing rod 1805 is provided on the inner wall of the flying shear blade 25. A rotating knob 1803 is fixedly connected to the left end of the fixing rod 1805. A fixing sleeve is provided on the outer wall of the left end of the fixing rod 1805. 1804, wherein the inner diameter of the left part of the fixing sleeve 1804 is smaller than the inner diameter of the right part; two limiting rods 1806 are fixedly connected to the outer wall of the right end of the fixing rod 1805; a blocking plate 1807 is slidably connected to the outer wall of the middle part of the fixing rod 1805; wherein the limiting groove 1802 is composed of two parts, the middle part of the left part is cylindrical with the same diameter as the diameter of the fixing rod 1805, and the two sides are two cuboids with the same height as the height of the limiting rods 1806; the right part is cylindrical with the same diameter and length as the blocking plate 1806. The diameter and length of rods 7 are consistent. A movable spring 1808 is provided on the outer wall of the fixed rod 1805. When the flying shear blade 25 needs to be installed, pressing the rotary knob 1803 moves the blocking plate 1807 to the right. Since the blocking plate 1807 and the fixed rod 1805 are slidably connected, the movable spring 1808 is compressed. The right end of the movable spring 1808 is fixed to the left side of the blocking plate 1807. Therefore, the movable spring 1808 deforms under the interaction of the rotary knob 1803 and the blocking plate 1807, producing… The elastic retaining rod 1805 passes through the flying shear blade 25 and enters the limiting groove 1802. At this time, rotating the rotating knob 1803 will cause the limiting rod 1806 to rotate, thereby locking the limiting rod 1806 at the right end of the limiting groove 1802, thus realizing the installation of the flying shear blade 25. When it is necessary to disassemble the flying shear blade 25, rotating the rotating knob 1803 will also cause the limiting rod 1806 to rotate, thereby allowing the limiting rod 1806 to be pulled out from the limiting groove 1802, thus realizing the disassembly of the flying shear blade 25.

[0034] Reference Figure 1A support block 19 is fixedly connected to the left side of the protective shell 2. The support block 19 is used to support the motor 7 and provide a force point for the motor 7 to prevent the motor 7 from falling during operation. A rubber pad 20 is fixedly connected to the top of the support block 19. The bottom of the motor 7 is fixedly connected to the top of the rubber pad 20. By setting the rubber pad 20 at the bottom of the motor 7, the noise generated by the motor 7 during operation can be reduced. A fixed frame 21 is fixedly connected to the front side of the protective shell 2. A display panel 22 is fixedly connected inside the fixed frame 21. By operating the display panel 22, the cutting speed and time interval of the drive component 1801 can be adjusted. A controller 23 is fixedly connected to the front side of the protective shell 2. The controller 23 is electrically connected to two pressure sensors 11. A pressure sensor 11 is installed at the rear end of the pull handle 12. When the pressure sensor 11 senses that the rear end of the pull handle 12 is under pressure, the pressure sensor 11 transmits a signal to the controller 23, thereby stopping the motor 7 from running. The multiple rollers 16 are arranged symmetrically at equal intervals.

[0035] Working principle: When adjusting the height, first pull the handle 12 away from the receiving groove 9, then start the motor 7. The gear 6 drives the toothed plate 8 to move. Pulling the handle 12 can drive the sliding plate 14 to squeeze the return spring 13 and deform it. When the height is adjusted to the appropriate position, release the handle 12. Due to the reset action of the return spring 13, the handle 12 is driven to move backward and enter the receiving groove 9. At this time, the pressure sensor 11 at the rear end of the handle 12 senses the pressure. The pressure sensor 11 controls the motor 7 to stop running. Through the limiting action of the handle 12 and the receiving groove 9, the toothed plate 8 is fixed, thereby achieving the effect of height adjustment.

[0036] When installing the flying shear blade 25, press the rotary knob 1803 to move the blocking plate 1807 to the right. Since the blocking plate 1807 and the fixed rod 1805 are slidably connected, and the right end of the movable spring 1808 is fixed to the left side of the blocking plate 1807, the movable spring 1808 will deform and generate elastic force under the cooperation of the rotary knob 1803 and the blocking plate 1807. The fixed rod 1805 passes through the flying shear blade 25 and enters the interior of the limiting groove 1802. At this time, rotate the rotary knob 1803, which will drive the limiting rod 1806 to rotate, thereby locking the limiting rod 1806 in the limiting groove 1802, thus realizing the installation of the flying shear blade 25. When it is necessary to disassemble the flying shear blade 25, rotate the rotary knob 1803 to rotate the limiting rod 1806, thereby allowing the limiting rod 1806 to be pulled out from the limiting groove 1802, thus realizing the disassembly of the flying shear blade 25.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
