Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a material strip buffer mechanism. Background Technology

[0002] The iron core is a crucial component of an electric motor, affecting not only its performance but also its production cost. With increasing motor production, the consumption of silicon steel for iron cores is enormous. Coupled with escalating international energy issues and rising steel prices, the technology of coiling and stacking motor iron cores has received widespread attention. Existing iron core strips require a coiling mechanism during coiling. To prevent misalignment and bending during the coiling process, the strip needs to be stretched to a certain distance for buffering before proper coiling. Due to the relatively long strip, the coiling mechanism requires a large footprint, which is inconvenient for the coiling operation. Utility Model Content

[0003] The purpose of this utility model is to design a tape buffer mechanism to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs a strip buffer mechanism, including a strip rack and a winding machine. The strip rack is provided with at least two spaced-apart conveyor rollers. The strip is conveyed sequentially through each conveyor roller and then enters the winding machine for winding. The strip rack is provided with a liftable pressure roller structure directly above each conveyor roller. The pressure roller structure presses down on the strip on the corresponding conveyor roller by lowering. The pressure roller structure controls the pressing height of the strip by adjusting the lifting height. The interval area between two adjacent conveyor rollers forms a first buffer area for the strip. A second buffer area is formed between the winding machine and the nearest conveyor roller. The strip rack is provided with sensors distributed with height difference at the first and second buffer areas.

[0005] Preferably, each conveying roller includes a roller body rotatably connected to the material rack, a synchronous belt pulley assembly driven by the roller body, and a first driving member connected to the synchronous belt pulley assembly and driving the synchronous belt pulley assembly to work.

[0006] Further optimization includes a fixed plate, a pressure roller mounted on the fixed plate, and a drive assembly mounted on the material rack and driving the fixed plate to rise and fall.

[0007] In a further optimization, the driving assembly includes a second driving component and a guide rod. The guide rod is disposed between the fixed plate and the material rack. The output end of the second driving component is connected to the fixed plate. The fixed plate moves up and down along the guide rod under the drive of the second driving component.

[0008] Further optimization involves providing two spaced pressure rollers on the fixed plate, which are symmetrically distributed along the vertical diameter of the roller body's cross-section towards the center line.

[0009] Preferably, the sensor includes a first sensor and a second sensor. Each first buffer area is provided with two sets of first sensors, which are located at the bottom of the material rack and near the bottom of the conveyor roller, respectively, to form a height difference. The second buffer area is provided with two sets of second sensors, one set of which is located at the bottom of the material rack and faces the bottom of the winding machine, and the other set of which is located on the material rack and faces the winding opening of the winding machine.

[0010] To further optimize the design, the roller body is provided with two symmetrically distributed conveying grooves, each conveying one material strip, so as to achieve synchronous conveying of the two material strips.

[0011] The technical advantages of this invention are as follows: the material rack is equipped with at least two spaced-apart conveyor rollers, and the material strip passes through the conveyor rollers in sequence. The gap between adjacent conveyor rollers serves as a buffer zone, allowing the material strip to sag and form a buffer. The material rack is equipped with two sets of sensors located in the buffer zone, and the two sets of sensors form a height difference to sense the material strip above and below, thereby monitoring the sag of the material strip and providing timely feedback to the conveyor rollers. This allows the conveyor rollers to tension or loosen the material strip by changing speed, thus achieving uniform forward movement of the material strip for winding. This not only ensures winding efficiency and quality but also reduces the footprint of the winding mechanism. Attached Figure Description

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] This utility model includes a material rack 1 and a winding machine 2. The material rack 1 is provided with at least two spaced conveyor rollers 3. All conveyor rollers 3 are spaced apart along the conveying direction of the material strip 9. The winding machine 2 is located after the last conveyor roller 3. The material strip 9 is conveyed through each conveyor roller 3 in sequence and then enters the winding machine 2 for winding. A certain interval is formed between adjacent conveyor rollers 3. A certain interval is also formed between the winding machine 2 and the last conveyor roller 3. The interval area between two adjacent conveyor rollers 3 forms the first buffer area 5 of the material strip 9. The second buffer area 6 is formed between the winding machine 2 and the last conveyor roller 3. When the material strip 9 is conveyed, the material strip 9 segments between adjacent conveyor rollers 3 can usually droop to a certain height to form a buffer. That is, the same material strip 9 can droop to form a buffer after passing through each first buffer area 5, and can also droop to form a buffer after passing through the second buffer area 6. In other words, the material strip 9 forms a multi-segment buffer before winding.

[0019] The material rack 1 has a lifting pressure roller structure 4 located directly above each conveyor roller 3. Each conveyor roller 3 has a corresponding pressure roller structure 4, which includes a pressure roller 42. The pressure roller 42 presses down on the material strip 9 on the corresponding conveyor roller 3 by lowering. The pressure roller structure 4 controls the degree and height of the pressure on the material strip 9 by adjusting the lifting height to accommodate material strips 9 of different thicknesses and models. When the material strip 9 is conveyed by the conveyor roller 3, the conveyor roller 3 adjusts the conveying speed of the material strip 9 by adjusting the rotation speed, thereby controlling the sag of the material strip 9 in each buffer zone, that is, controlling the degree of buffering.

[0020] The material rack 1 is equipped with sensors distributed at different heights in the first buffer area 5 and the second buffer area 6. These sensors are used to sense the position of the material strip 9 at different heights and to feed back the signals from the sensors to the control center, so that the rotation speed of the conveyor roller 3 is adjusted accordingly to achieve the normal conveying and winding speed.

[0021] Furthermore, the sensor includes a first sensor 7 and a second sensor 8. Each first buffer area 5 is provided with two sets of first sensors 7. The two sets of first sensors 7 are located at the bottom of the material rack 1 and below the conveyor roller 3, respectively, to form a height difference. The second buffer area 6 is provided with two sets of second sensors 8. One set of second sensors 8 is located at the bottom of the material rack 1 and faces the bottom of the winding machine 2. The other set of second sensors 8 is located on the material rack 1 and faces the winding opening 21 of the winding machine 2.

[0022] The sensor can be an infrared sensor, whose structure and working principle are conventional technologies and will not be described in detail here.

[0023] For example, after the conveyor roller 3 decelerates, the strip 9 droops and first passes the sensor located above. After drooping to a certain extent, the sensor located below senses the strip 9, thus knowing that the strip 9 is at its drooping limit. This information is then fed back to the control center, which then controls the conveyor roller 3 to accelerate or maintain a constant speed, so that the strip 9 is in a normal buffer state. Each buffer zone has a sensor, meaning that the amount of strip 9 buffered in each buffer zone can be monitored and fed back to the control center. The control center then coordinates the rotation speed of each conveyor roller 3, so that all conveyor rollers 3 rotate in a coordinated manner. Ultimately, the amount of each buffer in the strip 9 can be coordinated and controlled, allowing the strip 9 to be wound normally by the winding machine 2. In other words, the setting of the buffer zone allows the strip 9 to move forward at a constant speed during the winding process, ensuring smooth winding and avoiding winding accidents. At the same time, by controlling the conveying speed of the strip 9, it is prevented from being stretched too tightly, thereby ensuring the service life of the winding machine 2 and the winding quality of the strip 9.

[0024] Furthermore, each conveying roller 3 includes a roller body 31 rotatably connected to the material rack 1, a synchronous belt pulley assembly 33 that is driven by the roller body 31, and a first driving member 34 that is connected to the synchronous belt pulley assembly 33 and drives the synchronous belt pulley assembly 33 to work. The first driving wheel is driven by the synchronous belt pulley assembly 33 through the pulley, tensioner and synchronous belt, etc., to realize the automatic rotation of the roller body 31.

[0025] Furthermore, the pressure roller structure 4 includes a fixed plate 41, pressure rollers 42 mounted on the fixed plate 41, and a drive assembly mounted on the material rack 1 that drives the fixed plate 41 to rise and fall. The drive assembly includes a second drive member 43 and a guide rod 44. The guide rod 44 is disposed between the fixed plate 41 and the material rack 1. The output end of the second drive member 43 is connected to the fixed plate 41. Under the drive of the second drive member 43, the fixed plate 41 moves up and down along the guide rod 44. In this embodiment, the fixed plate 41 is provided with two spaced pressure rollers 42. The two pressure rollers 42 are symmetrically distributed along the vertical diameter of the cross-section of the roller body 31 towards the center line. That is, the two pressure rollers 42 can press on both sides above the conveyor roller 3, thereby making the conveying of the material belt 9 more accurate and convenient, and avoiding deformation or displacement of the material belt 9.

[0026] Furthermore, the roller body 31 is provided with two symmetrically distributed conveying grooves 32, each conveying groove 32 contains a material belt 9, and each conveying groove 32 corresponds to two pressure rollers 42, so as to realize the synchronous conveying of the two material belts 9 and improve the winding efficiency.

[0027] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
