Description

Technical Field

[0001] The utility model relates to the technical field of mica paper production, in particular to a mica paper feeding roller. Background Art

[0002] Insulation during motor winding installation is a crucial step in the motor manufacturing industry. To ensure safe and stable motor operation, the coils must be tightly wrapped with one or more layers of insulating material before being installed into the stator core. Mica paper, due to its excellent electrical insulation properties and heat resistance, is the preferred material for motor insulation. However, raw mica paper is large and long, making it inconvenient for direct use in the precise motor winding insulation process. Therefore, it must be cut into smaller sheets that meet the specific motor design specifications.

[0003] When processing traditional mica paper, a large area of mica paper is first compressed and continuously conveyed using a paper feed roller. This stage is intended to ensure the flatness and stability of the mica paper during transportation, preventing wrinkles or deviations. Subsequently, the mica paper is conveyed to a cutting device for precise cutting, dividing the large sheet of mica paper into small pieces of predetermined sizes to adapt to the size requirements of the motor windings. However, this step-by-step operation is not only complex and time-consuming, but may also reduce production efficiency due to the conversion process, increasing manpower and time costs. Most mica paper feed rollers currently on the market are simple in design and only have basic conveying functions. They lack integrated processing capabilities and cannot perform cutting tasks simultaneously during the conveying process. The mica paper needs to be conveyed to a dedicated cutting area for cutting, resulting in a relatively cumbersome mica paper production process. In response to the problems in the related art, no effective solution has been proposed. Therefore, it is necessary to propose a mica paper feed roller to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems in the related art, the utility model proposes a mica paper feeding roller to overcome the above technical problems existing in the existing related art.

[0005] To this end, the specific technical solutions adopted in this utility model are as follows:

[0006] A mica paper feeding roller comprises a fixed seat, a cutting roller is rotatably mounted on one side of the surface of the fixed seat, a squeezing roller is rotatably mounted below the cutting roller, transmission blocks are fixedly connected to both sides of the surface of the cutting roller, the ends of the transmission blocks are fixedly connected to a transmission housing, a contraction groove is provided on one side of the transmission housing, a telescopic spring is fixedly connected to the surface of one side of the cutting roller, the end of the telescopic spring is fixedly connected to a cutting blade, a cutting groove is provided on the surface of the squeezing roller, pushing columns are slidably mounted on both sides of the cutting roller, one end of the pushing column is fixedly connected to a conical cylinder, trapezoidal plates are fixedly connected to both sides of the surface of the cutting blade, electric push rods are fixedly mounted on both sides of the surface of the fixed seat, and the ends of the electric push rods are rollingly connected to the surface of one side of the pushing column.

[0007] Furthermore, in order to provide power for the rotation of the cutting roller and the squeezing roller, a transmission motor is fixedly installed on one side of the fixed seat, the transmission shaft of the transmission motor is fixedly connected to one end of the squeezing roller, a driving gear is fixedly installed on one side surface of the squeezing roller, and a driven gear is fixedly installed on one side surface of the cutting roller, and the driving gear is meshed with the driven gear.

[0008] Furthermore, in order to achieve a rolling connection between the end of the electric push rod and one side of the pushing column, a rolling groove is opened on one side surface of the pushing column, the end of the electric push rod is fixedly connected to a transmission rod, and a rolling wheel is rotatably installed on the surface of the transmission rod, and the rolling wheel is rotatably installed in the rolling groove.

[0009] Furthermore, in order to enable the cutting roller to drive the pushing column and the conical cylinder to rotate together, limiting blocks are fixedly connected on both sides of the surface of the cutting roller, and limiting grooves are opened on both sides of the inner walls of the pushing column and the conical cylinder, and the limiting blocks are slidably installed in the limiting grooves.

[0010] Furthermore, in order to enable the conical cylinder to drive the trapezoidal plate to move downward, the inclined surfaces of the conical cylinder and the trapezoidal plate cooperate with each other.

[0011] Furthermore, in order to realize the control of the extension and retraction of the cutting blade driven by the electric push rod, an encoder is rotatably mounted on one end of the cutting roller, and a controller is fixedly mounted on one side surface of the fixing seat.

[0012] Furthermore, in order to achieve positioning installation of the fixing seat, positioning plates are fixedly connected to both sides of the bottom surface of the fixing seat, and positioning holes are opened on the surface of the positioning plates.

[0013] The beneficial effects of the utility model are as follows: the extrusion roller and the cutting roller are driven to rotate by the transmission motor, so that the mica paper to be conveyed is squeezed and conveyed between the transmission housing and the extrusion roller; when the conveyed mica paper reaches the length required to be cut, the electric push rod drives the push column and the tapered cylinder to move toward the inside of the transmission housing, so that the inclined surface of the tapered cylinder squeezes the inclined surface of the trapezoidal plate, and then the trapezoidal plate drives the cutting blade to pass through the contraction groove and move into the cutting groove on the surface of the extrusion cylinder, and automatically cuts and intercepts the mica paper above the cutting groove. Compared with the transmission paper feeding roller, the device can realize automatic shearing while conveying the mica paper, and there is no need to send the mica paper to a separate cutting device for shearing, which greatly improves the production efficiency of the mica paper and effectively saves human resources and time costs.
