Description

Technical Field

[0001] This utility model relates to the field of sheet metal production technology, specifically to a magnetically wound belt at the tail of a continuous galvanizing production line for strip steel. Background Technology

[0002] Currently, in continuous galvanizing production lines, the continuous strip steel is cut before the coil winding process ends. The strip tail loses traction tension, and if it continues to be wound onto the winding machine, uncontrollable deviations occur, resulting in uneven outer rings on the coil. Traditional methods address this: Method 1 involves manual pushing or tapping to straighten the strip, which is labor-intensive and poses safety risks; Method 2 uses mechanical devices to laterally guide and limit the strip tail, but this damages the edges of the galvanized strip, and thinner sheets may even warp; Method 3 uses the speed difference between the pressure roller and the winding machine to create slight tension, but this cannot provide continuous control over the entire section, resulting in a loss of tension from the pressure roller to the strip tail, and the strip tail also loses tension as it passes the pressure roller.

[0003] Currently, a utility model patent with publication number CN212830848U discloses a magnetic belt conveyor mounting bracket with electrically controlled permanent magnets. One end of the bracket is equipped with a driven wheel, and the other end with a driving wheel. The conveyor belt is fitted onto both the driven and driving wheels. Multiple electrically controlled permanent magnets are mounted on a mounting plate in the middle of the bracket, and a motor reducer is mounted on one side of the driving wheel. When the motor reducer drives the driving wheel to rotate, the conveyor belt on the driving wheel drives the driven wheel to rotate. When a steel belt approaches the bottom of the electrically controlled permanent magnet inside the conveyor belt, the steel belt can be pulled to the target position, and then the corresponding electromagnetic coil is energized to generate an electromagnetic field that cancels out the magnetic field of the permanent magnet, thus unloading the attracted steel belt and completing the conveying process. The device can be demagnetized quickly by energizing and the permanent magnet magnetic field can be rapidly restored after power is cut off, meeting the requirements for rapid conveying in steel belt shearing applications. It is an energy-saving, fast, and low-wear magnetic conveyor belt for high-speed conveying of sheared steel belts.

[0004] As can be seen from the above-disclosed technical content, the utility model with announcement number CN212830848U, as existing technology, solves the problems of high energy consumption and short service life of electromagnet-based magnetic conveyor belts by incorporating a complex built-in electrically controlled permanent magnet. The permanent magnet magnetic field used when conveying steel belts is only energized for 1-2 seconds when unloading the steel belt. The electromagnetic coil's magnetic field cancels out the permanent magnet, thus demagnetizing it. Compared with the continuous energization of electromagnets, it saves more than 90% of energy, has very low energy consumption, and the electromagnetic coil does not heat up, effectively increasing the service life. However, the direct friction between the belt and the electrically controlled permanent magnet accelerates the wear and tear of the belt, leading to frequent maintenance and inconvenience in use. At the same time, the electrically controlled permanent magnet itself has a relatively complex structure and powerful functions, and can adapt to the working conditions of steel belt flying shears during plate transportation, which leads to its high cost. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a magnetic belt for continuous strip galvanizing production lines, which can effectively control the belt tail during steel coil winding at low cost, preventing belt tail slippage and winding deviation.

[0006] To achieve the above objectives, this utility model provides a magnetically wound belt for a continuous galvanizing production line of strip steel, comprising a belt support and a front pallet. A pallet rocker arm is mounted on the front of the belt support via a rotating shaft, and the front pallet is fixedly mounted on the top of the pallet rocker arm. A pallet angle control cylinder controls the pitching motion of the front pallet via the pallet rocker arm. A belt is mounted on the belt support via belt rollers, and multiple magnets are fixedly mounted on the belt support between the belt rollers. The magnets are located below the upward belt and are in contact with the upward belt.

[0007] In addition, the magnetically wound belt at the tail of the continuous galvanizing production line for strip steel proposed in the above embodiments of this utility model may also have the following additional technical features: As a further improvement of this utility model, the magnet is an electromagnet or a permanent magnet.

[0008] As a further improvement of this utility model, a belt drive motor is fixedly installed on the side of the belt bracket, and the belt drive motor drives the belt to rotate through a reducer and gears.

[0009] As a further improvement of this utility model, the surface of the magnet is smooth.

[0010] As a further improvement of this utility model, the upper surface of the magnet is provided with balls or rollers.

[0011] By means of the above solution, this utility model has at least the following advantages: compared with conventional belts, by adding magnets under the belt, the belt tail can be effectively controlled at low cost during the winding of the steel coil, preventing the belt tail from losing tension and preventing winding deviation.

Obviously, the drawings described below are only for this invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] The magnetically wound belt at the tail of the continuous galvanizing production line of strip steel of this utility model is described below with reference to the accompanying drawings.

[0015] In Embodiment 1 of this application, as Figure 1 and Figure 2 As shown, this continuous galvanizing production line for strip steel includes a magnetically wound belt at the tail (hereinafter referred to as "the present invention"). It comprises a belt support 1, a front pallet 2, a pallet angle control cylinder 3, a pallet rocker arm 4, a belt 5, a belt drive motor 6, and magnets 7. The pallet rocker arm 4 is mounted on the front of the belt support 1 via a rotating shaft. The front pallet 2 is fixedly mounted on the top of the pallet rocker arm 4. The pallet angle control cylinder 3 controls the pitching motion of the front pallet 2 via the pallet rocker arm 4. The belt 5 is mounted on the belt support 1 via belt rollers. Multiple magnets 7 are fixedly mounted on the belt support 1 between the belt rollers. The magnets 7 are located below and in contact with the upward-moving belt. The belt drive motor 6 is fixedly mounted on the side of the belt support 1. The belt drive motor 6 drives the belt 5 to rotate via a reducer and gears.

[0016] A magnetic belt conveyor with an electrically controlled permanent magnet (hereinafter referred to as "the patent"), disclosed in utility model publication number CN212830848U, solves the problems of high energy consumption and short service life of electromagnetic magnetic conveyor belts by incorporating a complex electrically controlled permanent magnet. The permanent magnet used in the conveying of the steel belt is only energized for 1-2 seconds when unloading the steel belt, and the electromagnetic coil's magnetic field cancels out the permanent magnet, thus demagnetizing it. Compared to the continuous energization of the electromagnet, this saves over 90% of energy, has very low energy consumption, and the electromagnetic coil does not heat up, effectively increasing its service life. However, the direct friction between the belt and the electrically controlled permanent magnet in the patent accelerates belt damage, leading to frequent maintenance and inconvenience. Furthermore, the electrically controlled permanent magnet itself has a complex structure and powerful functions, adapting to the conditions of steel belt shearing during sheet metal transport, resulting in higher costs. In contrast, this invention adds a simple magnet 7 under the belt 5, eliminating the need to control the magnetic strength; it only needs to prevent the belt tail from losing tension and thus prevents winding deviation.

[0017] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 2 As shown, the magnet 7 is an electromagnet or a permanent magnet. This allows for cost-effective control of the tail section.

[0018] To further optimize the working efficiency of this application and reduce wear on the belt 5, the surface of the magnet 7 is smooth. To minimize wear on the belt 5 and extend the service life of the equipment, the upper surface of the magnet 7 is provided with balls or rollers.

[0019] When in use, install the magnetic winding belt at the tail of the continuous galvanizing production line and connect it to the corresponding equipment, and the belt can be put into use.

[0020] When this utility model is used, its specific operation is as follows: In operation, the belt-driven motor 6 drives the belt 5 through a reducer and gear-driven rollers. The pallet angle control cylinder 3 controls the pallet rocker arm 4 by extending or retracting itself. The pallet rocker arm 4 drives the front pallet 2 to change its pitch angle for receiving the belt. The tail of the sheared belt is attracted by the magnet 7 under the upper surface of the belt 5, keeping the belt 5 and the tail relatively stationary, ensuring that the tail does not swing freely. The belt does not slip when passing through the swinging magnetic conveyor belt, and the belt is always in a stable and correct position before finally being fed into the winding machine.

[0021] In summary, the magnetically wound belt at the tail of the continuous galvanized steel strip production line of this utility model provides a more realistic tactile sensation during cardiopulmonary resuscitation (CPR) compressions by simulating pectoral muscles on a flat surface. The compression plate assembly inside the simulated chest cavity, simulating human ribs, provides good elastic feedback in conjunction with the elastic support component, resulting in a better compression experience. Simultaneously, the pressure alarm component located between the compression plate assembly and the first spring plate triggers the alarm device when the user applies excessive pressure, causing the trigger head to move to the trigger end to remind the user to reduce the pressure and keep it within a reasonable range to avoid injury to the patient.
