Description

Technical Field

[0001] This invention relates to the field of transformer processing technology, specifically to a high-efficiency winding device for iron cores used in the processing and production of small transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage, stepping up or down the voltage of electricity for convenient transmission and use. Transmission cables used in conjunction with transformers often require cutting to achieve the required dimensions due to their considerable length. During production and winding, a winding method is typically used for ease of packaging and transportation, where the entire cable is wound onto a reel. However, the length and weight of the cable reel, coupled with its relatively slippery insulation layer, make it prone to slippage during winding. This can lead to gaps between the reels, affecting their overall quality. Furthermore, current winding methods often lack the convenience of securing the core, resulting in uneven winding. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a high-efficiency winding device for iron cores in the processing and production of small transformers, which solves the problem of inconvenient guidance of the iron core during winding and the tendency for uneven winding.

[0005] The rotating mechanism includes a rotating shaft, a first bevel gear, a second bevel gear, a third bevel gear, and a grooved wheel. The outer wall of the first bevel gear is meshed with the second bevel gear, and the outer wall of the first bevel gear is meshed with the third bevel gear. A grooved wheel is provided between the third bevel gear and the second bevel gear.

[0006] Preferably, the rebound mechanism includes a sleeve, a baffle, a limiting groove, a second fixing plate, a limiting ball, and a first spring. The second fixing plate has a groove inside, and the first spring is fixedly connected inside the groove. One end of the first spring is fixedly connected to the limiting ball. The baffle is fixedly connected at the center of the sleeve. The sleeve has two limiting grooves inside, and the upper surface of the baffle is in contact with the lower surface of the limiting ball.

[0007] Preferably, the inner wall of the sleeve is in contact with one side of the outer wall of the threaded rod, the inner wall of the grooved wheel is fixedly connected to the outer wall of the threaded rod, the inner walls of the third bevel gear and the second bevel gear are rotatably connected to the outer wall of the threaded rod, and the output end of the first motor is fixedly connected to the lower end of the rotating shaft.

[0008] Preferably, a second limiting ring is fixedly connected to the center of the outer wall of the threaded rod, a slider is fixedly connected to one side of the outer wall of the second limiting ring, a top plate is fixedly connected to the upper surface of the side plate, a sliding groove is provided inside the top plate, and the outer wall of the slider is slidably connected to the inner wall of the sliding groove.

[0009] Preferably, the lower surface of the top plate is fixedly connected to a third fixing plate that is symmetrically arranged on the left and right. The lower surface of each of the third fixing plates is fixedly connected to a first limiting ring. The inner wall of each of the symmetrical first limiting rings is fixedly connected to a rubber ring, and a second spring is fixedly connected to one side of the outer wall of each of the first limiting rings.

[0010] Preferably, an mounting plate is fixedly connected to the upper surface of the base plate, a fixing block is fixedly connected inside the mounting plate, a third spring is fixedly connected to one side of the outer wall of the fixing block, a linkage rod is fixedly connected to one end of the third spring, and a first fixing column is rotatably connected to the lower end of the linkage rod.

[0011] Preferably, a second motor is fixedly connected to one side of the outer wall of the mounting plate, a first helical gear is fixedly connected to the output end of the second motor, and a non-uniform rotating block is fixedly connected to one side of the outer wall of the first helical gear.

[0012] Preferably, a movable block is fixedly connected to the upper middle end of one side of the outer wall of the linkage rod, a semi-circular plate is provided on the upper surface of the mounting plate, a second fixed column is provided inside the semi-circular plate, a second inclined gear is fixedly connected to one side of the outer wall of the second fixed column, the second inclined gear meshes with the first inclined gear, and a through hole is provided through the upper end of the inner side of the linkage rod.

[0013] Working Principle: When using this equipment, the transformer core is transmitted through the first limiting ring. A rubber ring protects the core from wear caused by friction with the edge of the first limiting ring during transmission due to excessive speed, which reduces production efficiency. The output of the first motor at the bottom of the workbench drives the first bevel gear on the upper end of the shaft to rotate. The first bevel gear drives the second bevel gear on the right and the third bevel gear on the left to rotate. The third bevel gear moves in the opposite direction to the second bevel gear, driving the threaded rod to rotate. The second limiting ring on the threaded rod moves linearly, and the slider on the side of the second limiting ring slides at the bottom of the top plate. The core passes through the left first limiting ring, enters the second limiting ring, and then enters the right first limiting ring. The second limiting ring moves left and right, guiding the core during transmission. When the second limiting ring contacts the second spring between the two first limiting rings, the spring rebounds due to the force, causing the second limiting ring to shift left and right along the threaded rod. The sleeve then compresses the limiting ring. The ball compresses the first spring. When it reaches the limiting groove and baffle on the rebound mechanism, the first spring rebounds, and the limiting ball bounces into it. When the limiting ball bounces into the limiting groove, the grooved wheel presses against the surface teeth of the second bevel gear, preventing the second bevel gear from rotating. The third bevel gear rotates counterclockwise, and the second limiting ring moves to the right. When the limiting ball bounces into the baffle, the grooved wheel presses against the surface teeth of the third bevel gear, preventing the third bevel gear from rotating. The second bevel gear rotates clockwise, and the second limiting ring moves to the left, thus achieving a reciprocating effect. The iron core enters through the top of the linkage rod and is then guided to the second fixed post through the side hole. The second motor drives the non-circular rotating block to rotate. The moving block slides on the side wall of the non-circular rotating block, causing the linkage rod to move back and forth beside the second fixed post. The third spring at the bottom resets the linkage rod. While the moving block rotates, the second inclined gear meshes and rotates, causing the second fixed post to rotate and cooperate with the linkage rod to complete the winding work, achieving the winding effect.

[0014] This invention provides a high-efficiency winding device for iron cores in the production of small transformers. It has the following features:

[0015] Beneficial effects:

[0016] 1. The present invention rotates the output end of the first motor, thereby driving the first bevel gear at the upper end of the shaft to rotate. The first bevel gear drives the second bevel gear on the right and the third bevel gear on the left to rotate. Through the counter-movement of the third bevel gear and the second bevel gear, the cooperation of the threaded rod, the second limiting ring, the slider and the first limiting ring guides the iron core in the transmission process.

[0017] 2. The present invention rotates the heterogeneous rotating block through the output end of the second motor, and achieves the winding effect through the cooperation of the heterogeneous rotating block, the moving block, and the moving linkage. Attached Figure Description
