Description

Technical Field

[0001] The utility model belongs to the technical field of efficient cutting of insulating paper, in particular to an insulating paper oblique shearing machine for mutual inductors. Background Art

[0002] Insulating paper is a common insulating material. Used in low-temperature environments, it's commonly used in motors, electrical appliances, instruments, switchgear, transformers, and other components. During the production process, the paper needs to be cut into specific sizes for packaging. When packaging transformer coils, the paper needs to be cut with an angled edge to prevent wrinkling.

[0003] Existing insulating paper cutting machines can only cut horizontally or vertically, and are not capable of cutting at an angle. When beveled cuts are required, manufacturers typically resort to manual cutting, which is not only labor-intensive but also inefficient. Furthermore, manual cutting results in inconsistent cut depths and angles, as well as uneven distances between cuts, impacting the quality and efficiency of subsequent transformer coil packaging. Summary of the Invention

[0004] The purpose of the utility model is to provide an insulating paper oblique shearing machine for mutual inductors, which has reasonable structure, safe and reliable use, neat and consistent incisions and improved product quality.

[0005] The technical solution of the utility model is as follows: it comprises a frame, a material guide device, a shearing device, a blanking device, and other parts. The shearing device is composed of a two-wheel rolling shearing assembly, a transmission mechanism, and an electrical control system. The two-wheel rolling shearing assembly is composed of a rolling support, a driven cutter wheel, a blade, a driven wheel shaft, a driven gear, a driving wheel shaft, a driving gear, a driving cutter wheel, and bearings. The rolling support is fixedly mounted on the work surface of the frame. The driven and driving shafts are respectively mounted with a driven cutter wheel and a driving cutter wheel. The driving and driven cutter wheels are respectively provided with driving and driven bevel grooves on the hubs at both ends of the driving and driven cutter wheels, and blades are mounted in the bevel grooves. The driving and driven cutter wheel assemblies are respectively mounted on the rolling support via bearings. The transmission mechanism is composed of a motor, a motor bracket, a small synchronous pulley, a large synchronous pulley, and a synchronous belt. The motor bracket is fixedly mounted below the frame and the work surface. The motor output shaft passes through the motor bracket and is then mounted with a small synchronous pulley. The small synchronous pulley is connected to the large synchronous pulley at the end of the driving wheel shaft of the two-wheel rolling shearing assembly via a synchronous belt. The electrical control system consists of an electrical box and a speed control knob, a start button and a stop button arranged on the electrical box; a material guide device is arranged on the feed port side of the double-wheel rolling shear assembly, and a material drop device is arranged on the discharge port side.

[0006] Furthermore, in order to prevent the synchronous belt from jumping due to being too loose, a synchronous belt tensioner consisting of a pressure wheel bracket and a pressure wheel is provided on one side of the synchronous belt of the transmission mechanism. The synchronous belt pressure wheel in the tensioner is fixed to the pressure wheel bracket by bolts.

[0007] Furthermore, the middle diameter of the driven cutter wheel and the active cutter wheel is twice the thickness of the insulating paper larger than that of the two ends. Bevel grooves are set on the smaller hubs at both ends according to the incision spacing and slope required by the production process. The inclination angle of the active bevel groove on the active cutter wheel is opposite to that of the driven bevel groove on the driven cutter wheel, and screw holes are set next to the bevel grooves set on the two end surfaces of the hub. The blades are fastened to the two ends of the driven cutter wheel and the active cutter wheel by screws, and key grooves are also set on the inner wall of the center hole of the driven cutter wheel and the active cutter wheel.

[0008] Furthermore, the material guide device consists of a material guide trough and a material guide trough base. The material guide trough is fixedly mounted on the work surface of the frame via the material guide trough base. An inverted "T"-shaped slide is provided on the upper portion of the material guide trough base, and positioning mounting ears are provided at the bottom of the material guide trough corresponding to the base, which are fixed together by bolts. To ensure that the insulating paper can smoothly enter the dual-wheel rolling shear assembly, a material guide trough pressure plate is installed at the feed end of the material guide trough and fixed to the material guide trough with screws.

[0009] Furthermore, the blanking device is composed of a blanking chute and a blanking chute base. The blanking chute is fixedly mounted on the work surface of the frame through the blanking chute base. The front end of the blanking chute is "V" shaped, and the upper surface of the blanking chute base is inclined, which facilitates the smooth entry and discharge of the cut insulation paper into the blanking chute.

[0010] The beneficial effects of the utility model are as follows: due to the adoption of the double-wheel bevel cutting and rolling shearing method, the problem that the existing shearing machine cannot achieve angled incisions is effectively solved, workers are liberated from manual labor, not only the labor intensity is reduced, but also the work efficiency is improved, especially the problems of inconsistent incision depth and angle and unequal distance between incisions caused by manual shearing are avoided, the shearing accuracy of the insulating paper is improved, and the product quality is improved.

The central diameter of the driven cutter wheel 21 and the active cutter wheel 34 is twice the thickness of the insulating paper larger than that of the two ends. Beveled cutter grooves are provided on the smaller hubs at both ends according to the incision spacing and slope required by the production process.

Screw holes 30 are provided next to the beveled cutter grooves provided on both end surfaces of the hub.

The output shaft of the motor 9 passes through the motor bracket 10 and is then installed with the small synchronous pulley 11. It is connected to the large synchronous pulley 12 provided at the end of the active wheel shaft 25 of the double-wheel rolling shear assembly 3 through the synchronous belt 13. The electrical control system consists of an electrical box 16 and a speed control knob 17, a start button 18, and a stop button 19 mounted on the box.

The driving gear 26 on the driving wheel shaft 25 drives the driven gear 24 to rotate in the same direction, so that the active cutter wheel assembly and the driven cutter wheel assembly in the double-wheel rolling shearing device 3 rotate in the same direction. At this time, the cut insulating paper is passed through the guide trough 4 through the guide trough pressure plate 6 and enters between the active cutter wheel assembly and the driven cutter wheel assembly. The insulating paper is squeezed and dragged forward by the thicker cutter wheel in the middle between the two cutter wheel assemblies, and the blades 22 on both sides cut the insulating paper into bevels on both sides, thereby meeting the needs of the production enterprise. Pressing the stop button 19 can achieve shutdown, and the speed knob 17 on the electrical box 16 can adjust the speed of cutting the insulating paper. The application of the utility model solves the problem that traditional shearing machines cannot cut oblique cuts, and liberates production workers from the heavy work of manual scissors, which not only reduces labor intensity but also improves work efficiency. In particular, it avoids the problems of inconsistent incision depth and angle, unequal distances between incisions, etc. caused by manual shearing, improves the shearing accuracy of insulating paper, and improves product quality.
