[0002] The transformer core is composed of multiple silicon steel sheets. During the production process, the silicon steel coil needs to be unfolded and punched, cut and processed into silicon steel sheets, and then the multiple silicon steel sheets are assembled as needed.

[0003] However, during the punching and slitting processes, jams may occur, preventing the subsequent silicon steel coils from moving forward, while the following silicon steel coils will continue to move forward under the traction of the traction mechanism, causing the unfolded silicon steel coils to be severely bent and produce irreversible deformation. If the transportation of the silicon steel coils is not stopped in time, a large number of silicon steel coils will be deformed and scrapped. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a transformer core silicon steel coil anti-blocking shutdown mechanism, which uses the deformation of the silicon steel coil to drive the gear lever to swing and drive the rotating shaft to rotate, and utilizes the separation and contact between the block and the sensor to control the start and stop of the traction mechanism, thereby achieving timely shutdown of the silicon steel coil after blockage occurs, avoiding deformation and scrapping of a large number of silicon steel coils.

[0005] The specific technical solution adopted by the utility model is:

[0006] A transformer core silicon steel coil anti-blocking shutdown mechanism, the anti-blocking shutdown mechanism is arranged above the slide of the workbench, the anti-blocking shutdown mechanism is located between the traction mechanism and the punching mechanism, the anti-blocking shutdown mechanism includes a rotating shaft, a gear lever, a fixed block and a sensor, the two ends of the rotating shaft are hinged to the two sides of the workbench and have the freedom of rotation, the fixed block is fixedly connected to the end of the rotating shaft, a block for blocking the sensing end of the sensor is arranged on the fixed block, the sensor is fixed on the workbench, the gear lever is located above the slide and clamps the steel coil together with the slide, the fixed end of the gear lever is fixedly connected to the rotating shaft, the free end of the gear lever swings with the help of the deformation of the steel coil and drives the rotating shaft to rotate, the fixed block swings with the help of the rotating shaft and drives the block away from the sensor, and the traction mechanism stops working with the separation of the block and the sensor.

[0007] The fixed end of the shift lever is in a C-shaped groove structure and forms a fixed groove, and the fixed groove clamps the rotating shaft and is fixed by tightening the opening of the fixed groove with a bolt.

[0008] The fixed end of the fixed block is sleeved and fixed with the end of the rotating shaft, the free end of the fixed block is an L-shaped structure bent to the side, the sensor is located at the angle of the bending of the fixed block, and the stopper is fixed to the free end of the fixed block and matches the sensor.

[0009] The anti-blocking shutdown mechanism also includes an arc-shaped upper pressure plate and a lower pressure plate. The upper pressure plate is located above the slide and fixedly connected to the workbench, and the lower pressure plate is located on the lower surface of the gear rod and fixedly connected to the gear rod.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] Specific implementation examples Figure 1-5 As shown, the utility model provides an anti-blocking shutdown mechanism for silicon steel coils of transformer core, the anti-blocking shutdown mechanism is arranged above the slide 2 of the workbench 1, and the anti-blocking shutdown mechanism is located between the traction mechanism and the punching mechanism, the anti-blocking shutdown mechanism includes a rotating shaft 3, a gear rod 4, a fixed block 5 and a sensor 7, both ends of the rotating shaft 3 are hinged to both sides of the workbench 1 and have the freedom of rotation, the fixed block 5 is fixedly connected to the end of the rotating shaft 3, a block 6 for blocking the sensing end of the sensor 7 is arranged on the fixed block 5, the sensor 7 is fixed on the workbench 1, the gear rod 4 is located above the slide 2 and clamps the steel coil together with the slide 2, the fixed end of the gear rod 4 is fixedly connected to the rotating shaft 3, the free end of the gear rod 4 swings with the help of the deformation of the steel coil and drives the rotating shaft 3 to rotate, the fixed block 5 swings with the help of the rotating shaft 3 and drives the block 6 away from the sensor 7, and the traction mechanism stops working with the separation of the block 6 and the sensor 7.

[0023] In the process of producing silicon steel sheets for transformer core, silicon steel coils need to be punched, slit and other processes to form silicon steel sheets. However, during the punching and slitting processes, jams may occur, and the following silicon steel coils will continue to move forward under the traction of the traction mechanism, causing the subsequent silicon steel coils to be unable to move forward normally and thus bend and deform. If the transportation of silicon steel coils is not stopped in time, a large number of silicon steel coils will be deformed and scrapped.

[0024] Therefore, the utility model is provided with an anti-blocking shutdown mechanism. When working, the silicon steel coil will pass along the limiting channel between the gear lever 4 and the slide 2. When the silicon steel coil in front is blocked, the silicon steel coil at the limiting channel will bend and form an arch. Since the curvature of the arch is small and relatively gentle, the bending of the silicon steel coil at this time is a reversible deformation. The arched silicon steel coil will lift the gear lever 4. After the gear lever 4 is lifted, the fixed block 5 is driven to be lifted with the help of the rotating shaft 3, and the block 6 on the fixed block 5 is away from the sensor 7. When the sensor 7 senses that the block 6 disappears, it sends a signal to the controller, and the controller stops the traction mechanism and shuts down. At this time, the staff will tidy up the stagnant place of the silicon steel coil, and flatten the silicon steel coil again, and then restart the traction mechanism to achieve timely shutdown after the silicon steel coil is blocked, avoiding deformation and scrapping of a large number of silicon steel coils.

[0025] In addition, the sensor 7 in the utility model can be a Hall sensor, wherein the sensor 7 is a Hall sensor, and the block 6 is a magnet. When the Hall sensor senses the magnet, the traction mechanism works normally, and when the Hall sensor cannot sense the magnet, the traction mechanism stops working.

[0026] like Figure 1-2 and Figure 5 As shown, the fixed end of the shift lever 4 is in a C-shaped groove structure and forms a fixed groove 8. The fixed groove 8 clamps the rotating shaft 3 and is fixed by tightening the opening of the fixed groove 8 with the help of bolts. The shift lever 4 in the utility model is fixedly connected with the rotating shaft 3 with the help of the fixed groove 8. When the fixed groove 8 matches the rotating shaft 3, the bolts are tightened to fit the two sides of the opening of the fixed groove 8, thereby forming an annular structure and clamping and fixing it with the rotating shaft 3.

[0027] like Figure 1-3 As shown, the fixed end of the fixed block 5 is sleeved and fixed with the end of the rotating shaft 3, and the free end of the fixed block 5 is an L-shaped structure bent to the side. The sensor 7 is located at the bent angle of the fixed block 5, and the stopper 6 is fixed to the free end of the fixed block 5 and matches the sensor 7. When the silicon steel coil is not deformed, in order to ensure that the stopper 6 and the sensor 7 can sense each other, it is necessary to keep the two parallel. Therefore, the utility model is also provided with a third adjusting bolt 14 below the fixed block 5. By adjusting the third adjusting bolt 14, the height of the fixed block 5 in the initial position can be adjusted, thereby ensuring that the stopper 6 and the sensor 7 can sense each other. At the same time, by adjusting the third adjusting bolt 14, the height of the limiting channel can also be controlled, thereby adapting to silicon steel coils of different thicknesses.

[0028] like Figure 1-2 and Figure 4As shown, the anti-blocking shutdown mechanism also includes an arc-shaped upper pressure plate 9 and a lower pressure plate 10, the upper pressure plate 9 is located above the slide 2 and is fixedly connected to the workbench 1, the lower pressure plate 10 is located on the lower surface of the gear lever 4 and is fixedly connected to the gear lever 4, and an arched limiting channel is clamped between the upper pressure plate 9 and the lower pressure plate 10. When the silicon steel coil is blocked, the silicon steel coil in the limiting channel may form a V-shaped bend. When the V-shaped bend occurs, the silicon steel coil may not be able to lift the gear lever. Therefore, the limiting channel in the utility model is arched. When the silicon steel coil is blocked and tends to bend, the silicon steel coil in the limiting channel will definitely bend in an arched shape and lift the gear lever 4.

[0029] In addition, in order to ensure that the silicon steel coil can be bent in the limiting channel, a cover plate 15 is further provided in the utility model. Except for the limiting channel, the cover plate 15 is provided above the slide 2 in the remaining positions. The slide 2 and the cover plate 15 form a conveying channel. The conveying channel can limit the vibration and deformation of the silicon steel coil, thereby ensuring that the silicon steel coil can be bent in the limiting channel.

[0030] like Figure 4 As shown, both ends of the upper pressure plate 9 are fixedly connected to the workbench 1 by means of bolts, and a first adjusting bolt 11 is arranged between the middle part of the upper pressure plate 9 and the workbench 1, one end of the first adjusting bolt 11 is threadedly connected to the workbench 1, and the other end of the first adjusting bolt 11 abuts against the lower surface of the upper pressure plate 9, and the curvature of the upper pressure plate 9 is adjusted by means of the first adjusting bolt 11.

[0031] like Figure 4 As shown, the middle part of the lower pressure plate 10 is fixedly connected to the shift rod 4 by means of bolts, and second adjusting bolts 12 are respectively arranged between the two ends of the lower pressure plate 10 and the shift rod 4, one end of the second adjusting bolt 12 is threadedly connected to the shift rod 4, and the other end of the second adjusting bolt 12 abuts against the upper surface of the lower pressure plate 10, and the curvature of the lower pressure plate 10 is adjusted by means of the second adjusting bolt 12. Due to the different thicknesses of the silicon steel coils, the arch curvature of the limiting channel must also be adaptively adjusted. When the silicon steel coil is thinner, the curvature of the limiting channel is small, and when the silicon steel coil is thicker, the curvature of the limiting channel is large. In order to facilitate the adjustment of the curvature of the limiting channel, the upper pressure plate 9 and the lower pressure plate 10 in the utility model are adjusted by the first adjusting bolt 11 and the second adjusting bolt 12 respectively. When the first adjusting bolt 11 and the second adjusting bolt 12 are rotated clockwise, the curvature of the limiting channel gradually becomes smaller, and when the first adjusting bolt 11 and the second adjusting bolt 12 are rotated counterclockwise, the curvature of the limiting channel gradually becomes larger.

[0032] like Figure 4As shown, the end of the lower pressure plate 10 protrudes from the free end of the shift rod 4, and a baffle 13 is provided at the end of the lower pressure plate 10. The baffle 13 is an inclined sheet structure from top to bottom along the traction direction of the silicon steel coil. In order to ensure that the silicon steel coil can smoothly enter the limiting channel, the baffle 13 is provided in the utility model to form a guiding effect to ensure that the silicon steel coil enters the limiting channel.
