Description

Technical Field

[0001] The utility model relates to the field of blanking equipment, in particular to a blanking equipment for wrapping materials of a transformer body. Background Art

[0002] In power systems, instrument transformers (MTs), as power conversion devices, primarily convert high voltage to low voltage and high current to low current for measurement, protection, and monitoring. The core and coil are the core components of a MT, so they require multiple shielding and buffer layers to ensure uniform electric field distribution and mitigate factors such as unstable partial discharge (PD) caused by uneven field strength. This effectively reduces PD, improves the MT's qualification rate, and ensures long-term stable operation.

[0003] At present, the shielding layer is mostly made of semiconductor crepe paper and semi-conductive self-adhesive tape, and the buffer layer is mostly made of crepe paper, polyester film, insulating self-adhesive tape, etc., and when winding the transformer's core and coil with multiple shielding layers and buffer layers, workers are generally required to hold rolled wrapping materials and wrap them layer by layer.

[0004] However, due to the large volume of the wrapping material rolls such as semiconductor crepe paper and semi-conductive self-adhesive tape sold on the market, coupled with the structural limitations of the transformer itself, when workers wrap the iron core and coil in circles, not only will there be a problem of frequent wrapping, but they will also often face operational inconveniences due to the size of the wrapping materials, resulting in a cumbersome and lengthy wrapping process, which in turn affects the overall production efficiency and creates a significant efficiency bottleneck. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a material unloading device for the transformer body wrapping material, and to enable it to wind a large roll of wrapping material into multiple layers of small rolls of wrapping material, so as to facilitate the subsequent manual wrapping by the staff, thereby reducing the wrapping frequency and labor loss in the body wrapping process and improving production efficiency.

[0006] In order to solve the above technical problems, the utility model provides a blanking device for the wrapping material of the transformer body, which includes a base, a support frame and a driving motor are provided on the base, a mounting plate is provided on the upper part of the support frame, at least two loading racks are installed on one side of the mounting plate, each loading rack is provided with a rotating wheel on the outer side, and each loading rack is detachably installed with a baffle 1 on the end away from the mounting plate; a conveying rack is provided at the lower part of the support frame, and baffle 2 is provided at both ends of the conveying rack; the output end of the driving motor is transmission-connected to a gearbox, and a blanking rack is fixedly installed on the output end of the gearbox, and a baffle 3 is fixedly installed on one end of the blanking rack, and two parallel clamping rods are provided on the side of the baffle 3 away from the blanking rack. Based on this, during the body wrapping operation of the transformer, the staff can first use the utility model to roll the large roll of wrapping material into a small roll multi-layer structure, that is, they can first put multiple large rolls of wrapping material on the rotating wheel at the loading rack, and then overlap the beginning of each roll of wrapping material and bypass the conveyor rack at the same time, and finally wrap the beginning of each roll of wrapping material in an S-shaped structure and place it on two clamping rods, and realize the multi-layer small roll winding of wrapping materials such as crepe paper under the drive of the drive motor and the gearbox, so as to facilitate the staff to carry out subsequent manual wrapping operations, reduce the frequency of wrapping and labor loss in the body wrapping process, and improve production efficiency.

[0007] Furthermore, all the loading racks are detachably connected to the same baffle, and the baffle blocks the wrapping materials set on each loading rack to prevent them from falling off during the rotation process.

[0008] Furthermore, each loading rack is detachably mounted with a baffle plate 1 at its end. If the specifications of the bandage materials placed on each loading rack are different, when loading and unloading the bandage materials on the loading rack, the baffle plate 1 at the corresponding loading rack can be removed according to the actual situation, effectively preventing the bandage materials on other loading racks from falling off.

[0009] Furthermore, the drive motor is a permanent magnet DC motor.

[0010] Furthermore, the baffle 2 and the baffle 3 are in the shape of a circular ring, and are respectively installed on the conveying rack and the unloading rack.

[0011] Furthermore, the baffle plate 2 is threadedly mounted on the outer side of the conveying frame, and the position of the baffle plate 2 can be adjusted by rotating the baffle plate 2 to accommodate wrapping materials of different widths.

[0012] Furthermore, the two clamping rods include a fixed clamping rod and a movable clamping rod. One end of the fixed clamping rod is fixedly mounted on the surface of baffle plate 3, while one end of the movable clamping rod passes through an elongated hole formed in the surface of baffle plate 3 and is then threadedly connected to a locking nut. Thus, by adjusting the position of the movable clamping rod within the elongated hole, the distance between the movable clamping rod and the fixed clamping rod can be adjusted to ensure that the opening ends of multiple wrapping materials are better secured, thereby ensuring the overall winding effect.

[0013] Furthermore, a protective cover is provided on the upper end cover of the base, and the support frame and the motor are installed in the protective cover. The protective cover ensures that the entire unloading environment has a high cleanliness level, preventing dust, impurities, etc. from contaminating the wrapping materials and thus affecting the insulation performance of the transformer.

[0014] It can be seen from the above technical scheme that the utility model has the following advantages: First, the utility model can wind a large roll of wrapping material into multiple layers of small rolls of wrapping material, so as to facilitate the subsequent manual wrapping by the staff, thereby reducing the frequency of wrapping and labor loss in the process of wrapping the device body, and improving production efficiency; secondly, the utility model is only composed of a simple drive motor, a gearbox, a loading rack, a unloading rack and other structures, which has the advantages of simple structure and simple operation; at the same time, the utility model can also realize the winding of wrapping materials of different widths by adjusting the second position of the baffle, and ensure the consistency of the unloading length by controlling the speed and rotation time of the gearbox and the drive motor.
