Description

Technical Field

[0001] The invention belongs to the technical field of efficient cutting of insulating paper, and in particular relates to an insulating paper oblique cutting machine for a mutual inductor. Background Art

[0002] Insulation paper is a common insulating material. As an electrical insulation paper used under low temperature conditions, it is commonly used to supply motors, electrical appliances, instruments, switch transformers, mutual inductors, etc. and their components. In the production process, the insulation paper needs to be cut into certain sizes for packaging. When packaging the mutual inductor coil, it needs to be cut into an oblique edge. The insulating paper with an oblique edge will not wrinkle when packaging the mutual inductor coil.

[0003] Existing insulating paper cutting machines can only cut horizontally or vertically, and there is no cutting with an inclined angle. When production companies need to cut oblique edges, they usually use manual cutting, which is not only labor-intensive but also inefficient. In particular, the depth and angle of the cuts made by manual cutting are not consistent, and the distance between the cuts is not equal, which affects the subsequent packaging quality and efficiency of the transformer coil. Summary of the invention

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

[0005] The technical solution of the present invention is: it is composed of parts such as a frame, a material guiding device, a shearing device, a blanking device, etc. The shearing device is composed of a double-wheel rolling shearing assembly, a transmission mechanism and an electrical control system. The double-wheel rolling shearing device is fixedly installed on the working table of the frame, driven by the transmission mechanism arranged on the frame, and controlled by the electrical control system. A material guiding device is arranged at the feed port, and a blanking device is arranged at the discharge port.

[0006] Furthermore, the double-wheel rolling shear assembly is composed of a rolling support seat, 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 a bearing. The rolling support seat is fixedly installed on the work surface of the frame. The driven wheel shaft and the driving wheel shaft are respectively installed with a driven cutter wheel and an active cutter wheel. The active cutter wheel and the driven cutter wheel hub at both ends are respectively provided with an active bevel groove and a driven bevel groove, and the blades are installed in the bevel groove to form an active cutter wheel assembly and a driven cutter wheel assembly, which are respectively installed on the rolling support seat through bearings. The transmission mechanism is composed of a motor, a motor bracket, a small synchronous wheel, a large synchronous wheel, a synchronous belt, etc. The motor bracket is fixedly installed under the frame and the work surface. The motor output shaft passes through the motor bracket and then a small synchronous wheel is installed, which is connected to a large synchronous wheel set at the end of the driving wheel shaft of the double-wheel rolling shear assembly through a synchronous belt. The electrical control system is composed of an electrical box and a speed regulating knob, a start button and a stop button arranged on the electrical box; a material guiding device is arranged on the feeding port side of the double-wheel rolling shearing assembly, and a material dropping device is arranged on the discharging port side.

[0007] Furthermore, in order to prevent the synchronous belt from jumping teeth 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.

[0008] Furthermore, the middle diameters of the driven cutter wheel and the active cutter wheel are twice the thickness of the insulating paper than those at the two ends. Beveled cutter grooves are arranged on the smaller hubs at the two ends according to the incision spacing and slope required by the production process. The inclination angles of the active beveled cutter grooves on the active cutter wheel and the driven beveled cutter grooves on the driven cutter wheel are opposite, and screw holes are arranged next to the beveled cutter grooves arranged 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 keyways are also arranged on the inner walls of the center holes of the driven cutter wheel and the active cutter wheel.

[0009] Furthermore, the material guide device is composed of a material guide trough, a material guide trough base, etc., and the material guide trough is fixedly mounted on the work surface of the frame through the material guide trough base. An inverted "T"-shaped slideway is arranged on the upper part of the material guide trough base, and a positioning mounting ear is arranged at the bottom of the material guide trough corresponding to the base, which is fixedly connected by bolts. In order to ensure that the insulating paper smoothly enters the double-wheel rolling shear assembly, a material guide trough pressure plate is arranged at the feed inlet end of the material guide trough and fixed to the material guide trough by screws.

[0010] Furthermore, the blanking device is composed of a blanking trough and a blanking trough base, and the blanking trough is fixedly mounted on the work surface of the frame through the blanking trough base. The front end of the blanking trough is in a "V" shape, and the upper surface of the blanking trough base is an inclined surface, which facilitates the sheared insulation paper to smoothly enter the blanking trough and be discharged.

[0011] The beneficial effects of the present invention are as follows: by adopting a double-wheel bevel 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 different incision depths and angles and unequal distances between incisions caused by manual shearing are avoided, the shearing accuracy of insulating paper is improved, and product quality is improved.

The middle diameter of the driven cutter wheel 21 and the active cutter wheel 34 is twice the thickness of the insulating paper than that of the two ends. The inclined cutter grooves are set on the smaller hubs at the two ends according to the incision spacing and slope required by the production process. The active inclined cutter groove 35 on the active cutter wheel 34 is opposite to the inclined angle of the driven inclined cutter groove 29 on the driven cutter wheel 21, and screw holes 30 are set next to the inclined cutter grooves set on the two end surfaces of the hub.

The output shaft of the motor 9 passes through the motor bracket 10 and then the small synchronous wheel 11 is installed, which is connected to the large synchronous wheel 12 set 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 is composed of an electrical box 16 and a speed knob 17, a start button 18 and a stop button 19 arranged on the electrical box.

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 oblique cuts 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 the shearing of the insulating paper.
