Abstract
Description
Technical Field
[0001] This utility model belongs to the field of winding machine technology, specifically a winding machine inlet anti-breakage structure. Background Technology
[0002] Winding machines are an important processing and production equipment widely used in the electronics and electrical appliance industry. Their purpose is to wind inductor coils using enameled copper wire. Winding machines are mechanical equipment with high requirements for speed and precision control. The control components are required to provide very precise and smooth linear speed and flexible commutation capability. At present, the winding machine market is huge and has a wide variety of products, including parallel winding machines, toroidal winding machines, stator and rotor winding machines, textile winding machines, voice coil winding machines, etc.
[0003] Meanwhile, the announcement (No. 202211029144.0) discloses "A dual-wheel wire storage assembly for a winding machine". The assembly includes: a mounting plate, a first wire storage wheel and a second wire storage wheel sequentially arranged on one side of the mounting plate, a guide wire sleeved on the first wire storage wheel and the second wire storage wheel, a winding station formed on the guide wire on one side of the first wire storage wheel and the second wire storage wheel, and a wire pressing belt that fits against the first wire storage wheel and the second wire storage wheel on the other side. The guide wire pulls copper wire to wind around the wire grooves of the first wire storage wheel and the second wire storage wheel. One side of the copper wire passes through the winding station, and the other side is pressed against the wire grooves of the first wire storage wheel and the second wire storage wheel by the action of the wire pressing belt.
[0004] The aforementioned dual-wheel wire storage assembly for winding machines lacks a tension adjustment component during use. If the tension is too low when the copper wire is fed in, the copper wire in the wire groove on the storage wheel will be loosely arranged and overlapped. If the tension is too high, the copper wire may be overstretched (especially for soft copper wire), resulting in thinner wire diameter or breakage. Furthermore, continuous friction will occur when the copper wire passes through the wire hole of the wire guide rod at high speed, which can easily lead to insulation wear (such as paint peeling off the enameled wire) or scratches on the surface of the copper wire, affecting product performance.
[0005] Therefore, a structure to prevent breakage of the winding machine's inlet wire is proposed to address the above problems. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides a wire breakage prevention structure for winding machines. It features adjustable tension of the incoming wire via a tension adjustment component, allowing dynamic tension adjustment based on the material and thickness of the incoming wire. This prevents wire breakage due to abnormal tension, thus protecting the incoming wire. Simultaneously, the evenly distributed circumferentially distributed oil outlet micro-holes allow lubricating oil to form a slow-release layer along the inner wall of the wire hole, reducing dry friction between the wire and the hole wall and minimizing the aging of the wire insulation layer or metal fatigue fracture caused by frictional heat.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a winding machine inlet anti-breakage structure, including a mounting plate, on which a double-wheel wire storage assembly body is provided, and at the upper end of the mounting plate are respectively provided a wire guide rod and a wire feeding guide wheel, and a tension adjustment assembly is provided between the wire guide rod and the wire feeding guide wheel, the tension adjustment assembly including a mounting bracket, a guide pulley, a guide rail, a sliding seat, a pressure guide wheel, a fixing block, a cylinder, a connector and a tension spring, and an oil storage chamber is provided inside the wire guide rod.
[0008] Preferably, the mounting bracket of the tension adjustment component is fixed on the mounting plate, the guide rail is mounted on the mounting bracket, and the sliding seat is slidably connected to the guide rail.
[0009] Preferably, the fixing block and the guide pulley are respectively disposed at both ends of the mounting bracket, the cylinder is installed on one side of the fixing block, the output end of the cylinder is connected to the connector, and the tension spring is disposed between the connector and the sliding seat.
[0010] Preferably, the sliding seat has a spring fixing member at one end facing the tension spring, and the two ends of the tension spring are respectively connected to the ends of the spring fixing member and the connector by hooks.
[0011] Preferably, the guide pulley and pressure guide wheel of the tension adjustment assembly are parallel to the axis of the wire feeding guide wheel, and the copper wire passes through the wire hole rod, guide wheel, pressure guide wheel and wire feeding guide wheel in sequence and is connected to the guide wire of the dual-wheel wire storage assembly body.
[0012] Preferably, the oil storage cavity is arranged in a ring shape at the edge of the wire hole of the wire rod, and an oil-absorbing sponge is provided on the inner wall of the guide hole of the wire rod.
[0013] Preferably, the oil storage chamber has a plurality of oil outlet micro-holes evenly arranged on the side near the wire hole, and the top of the oil storage chamber is provided with an oil inlet, which is equipped with a sealing cap.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model uses a cylinder of the tension adjustment component, a connector and a tension spring to drive the sliding seat to slide on the guide rail, adjust the position of the pressure guide wheel, and adjust the tension of the incoming wire with the guide pulley. The tension can be dynamically adjusted according to the incoming wire of different materials and thicknesses, so as to avoid the incoming wire from breaking due to abnormal tension and play a role in protecting the incoming wire.
[0016] 2. This utility model uses circumferentially distributed oil outlet micropores to form a slow-release layer of lubricating oil along the inner wall of the wire hole. The oil-absorbing sponge prevents the lubricating oil from dripping or evaporating rapidly, thus achieving continuous lubrication, reducing dry friction between the wire and the hole wall, and reducing the aging of the wire insulation layer or metal fatigue fracture caused by frictional heat.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The following describes an embodiment of this utility model based on its overall structure.
[0027] like Figures 1 to 5As shown, this utility model provides a wire inlet anti-breakage structure for a winding machine, including a mounting plate 1. A double-wheel wire storage assembly body 2 is provided on the mounting plate 1. The structure of the double-wheel wire storage assembly body 2 is the same as that in the prior art. A wire guide hole rod 3 and a wire feeding guide wheel 4 are respectively provided at the upper end of the mounting plate 1. A tension adjustment assembly 5 is provided between the wire guide hole rod 3 and the wire feeding guide wheel 4. The tension adjustment assembly 5 includes a mounting bracket 51, a guide pulley 52, a guide rail 53, a sliding seat 54, a wire pressing guide wheel 55, a fixing block 56, a cylinder 57, a connector 58, and a tension spring 59 to adjust the tension of the inlet wire. An oil storage chamber 6 is provided inside the wire guide hole rod 3.
[0028] In this embodiment, the mounting bracket 51 of the tension adjustment component 5 is fixed on the mounting plate 1 by bolts. The guide rail 53 is set on the mounting bracket 51, and the sliding seat 54 is slidably connected to the guide rail 53 by a linear bearing. The fixing block 56 and the guide pulley 52 are respectively set at both ends of the mounting bracket 51. The cylinder 57 is installed on one side of the fixing block 56. The output end of the cylinder 57 is connected to the connector 58. A pressure sensor and a controller are connected to the cylinder 57. The pressure sensor is used to monitor the output pressure of the cylinder 57 in real time and feed the pressure signal back to the controller. The controller precisely adjusts the tension spring 59 by controlling the output force of the cylinder 57 according to the preset tension value range, thereby achieving precise control of the incoming wire tension. The tension spring 59 is set between the connector 58 and the sliding seat 54. A spring fixing member is set at the end of the sliding seat 54 facing the tension spring 59. The two ends of the tension spring 59 are connected to the spring fixing member and the end of the connector 58 respectively by hooks. During the wire feeding process, the output force of the cylinder 57 acts on the tension spring 59 through the connector 58. The tension spring 59 pulls the sliding seat 54 to slide on the guide rail 53, so that the pressure guide wheel 55 and the guide pulley 52 cooperate to apply tension to the incoming wire.
[0029] The guide pulley 52 and the wire pressing guide wheel 55 of the tension adjustment component 5 are parallel to the axis of the wire feeding guide wheel 4. The copper wire passes through the wire hole rod 3, the guide wheel, the wire pressing guide wheel 55, and the wire feeding guide wheel 4 in sequence and then connects to the guide wire of the double wheel wire storage component body 2. The surfaces of the guide pulley 52 and the wire pressing guide wheel 55 are provided with a layer of rubber or silicone anti-slip material to increase the friction between the wire and the pulley and guide wheel and prevent the wire from slipping during transmission.
[0030] The oil storage chamber 6 is arranged in a ring at the edge of the wire hole of the wire hole rod 3. An oil-absorbing sponge 7 is provided on the inner wall of the guide hole of the wire hole rod 3. Multiple oil outlet micro-holes are evenly arranged on the side of the oil storage chamber 6 near the wire hole. An oil filling port 8 is provided on the top of the oil storage chamber 6. The oil filling port 8 is equipped with a sealing cap. An inlet guide flare is provided at the end of the wire hole rod 3 near the wire inlet. The inner wall of the flare is smooth, and its diameter gradually decreases from the outside to the inside, which facilitates the smooth entry of the wire into the wire hole rod 3 and reduces the possibility of the wire breaking due to collision with the hole wall.
[0031] The cylinder is existing technology and will not be described in detail. This invention also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model should be selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.
[0032] The working principle and process of the anti-breakage structure for the wire inlet of the winding machine: When the winding machine is working, the wire inlet passes sequentially through the wire hole rod 3, guide pulley 52, pressure guide wheel 55, and wire feeding guide wheel 4, and then connects to the guide line of the double-wheel wire storage assembly body 2. During the wire inlet process, the output force of the cylinder 57 acts on the tension spring 59 through the connector 58. The tension spring 59 pulls the sliding seat 54 to slide on the guide rail 53, so that the pressure guide wheel 55 and the guide pulley 52 cooperate to apply tension to the wire inlet. When the wire inlet tension changes, the pressure sensor monitors the output pressure of the cylinder 57 in real time and feeds the signal back to the controller. The controller then... According to the preset tension value range, the tension spring 59 is precisely adjusted by adjusting the output force of cylinder 57, thereby achieving dynamic control of the incoming wire tension. This ensures that the incoming wire is transmitted under appropriate tension, avoiding breakage due to excessive tension or affecting the winding quality due to insufficient tension. During the incoming wire feeding, the annular oil storage chamber 6 inside the wire hole rod 3 stores lubricating oil. The lubricating oil seeps out evenly through the oil outlet micro-hole near the wire hole and is absorbed by the oil-absorbing sponge 7 on the inner wall of the guide hole. When the incoming wire passes through the wire hole rod 3, the lubricating oil in the oil-absorbing sponge 7 can reduce the friction between the incoming wire and the hole wall, reduce wear, and reduce the risk of breakage caused by friction and jamming.
