Description

Technical Field

[0001] This utility model relates to a slip-ring mechanism, and more particularly to a winding device for online control of magnetic induction heating. Background Technology

[0002] The magnetically controlled winding device uses magnetic induction to achieve slip control. Based on its working principle, it generates heat during the winding process.

[0003] When facing high tension or long winding time, heat will accumulate in the slip ring, which can easily cause thermal failure. This is especially true for magnetically controlled slip rings. Due to the nature of the magnet itself, it is more sensitive to temperature than mechanical ones. Excessive temperature will cause the magnet to lose magnetism. Therefore, a good cooling effect is required to improve the stability of the equipment and also improve its working performance to a certain extent. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a winding device for online control of magnetic induction heating to solve at least one of the above problems.

[0005] A winding device for online control of magnetic induction heating includes a main shaft; a slip ring disposed on the main shaft; the main shaft includes an air inlet component for connecting to an air source and an air outlet for discharging air, the air inlet component and the air outlet being connected by a gas flow channel;

[0006] There are several air outlets, and the air outlets are on the circumferential surface of the main shaft. The cooling gas flow rate is adjusted to achieve homogenized heat conduction along the axial direction.

[0007] A proportional solenoid valve is installed between the air intake component and the air source, and the proportional solenoid valve is connected to the industrial control signal of the winding equipment.

[0010] The cold end pipe is connected to the gas flow channel, the hot end pipe faces the outside of the main shaft, and the gas source connector is connected to a gas source.

[0011] As a further embodiment of this utility model: the air intake component is externally mounted on the main shaft, and the air intake component is connected to the gas flow channel through an air pipe.

[0012] As a further embodiment of this utility model: the air outlet is divided into several groups, each group having several air outlets, and the air outlets in the same group are circumferentially distributed on the main shaft.

[0014] As a further aspect of this utility model: starting from the air intake component, the area of ​​each group of air outlets gradually increases towards the farthest group of air outlets.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Embodiment 1 of this utility model, combined with Figures 1-5 As shown, an online control of magnetic induction heating winding device is provided, including a main shaft 100; a slip ring 200 disposed on the main shaft 100, an air gap between the main shaft 100 and the slip ring 200, and low temperature gas being supplied from the main shaft 100 to the slip ring 200 to achieve temperature control of the slip ring 200.

[0028] The main shaft 100 includes an air inlet component 110 for connecting to an air source and an air outlet 120 for discharging air. The air inlet component 110 and the air outlet 120 are connected by a gas flow channel 130. The gas flow channel 130 is an axial channel within the main shaft 100. The end of the gas flow channel 130 away from the air inlet component 110 is closed, and the airflow entering the gas flow channel 130 from the air inlet component 110 is discharged only from the air outlet 120.

[0029] It's important to know that the intake component 110 is the core component of the refrigeration system, the vortex tube, used to generate the low-temperature gas required for cooling. Due to certain operating conditions, refrigeration equipment with internal media circulation, such as chillers or freezers, is not permitted because of the risk of cooling medium leakage. Ordinary air cooling is insufficient to meet the cooling demands of high-speed differential (high-torque winding conditions). The vortex tube uses compressed air as its cooling source, eliminating any risk of leakage or contamination. The generated low-temperature gas can quickly remove heat from the magnetically controlled differential ring, improving equipment performance while saving energy and protecting the environment.

[0030] There are several air outlets 120, and the air outlets 120 are located on the circumferential surface of the main shaft 100. This can be understood as air outlets 120 being radial through holes on the circumferential surface of the main shaft 100, guiding cold air from the gas flow channel 130 to the slip ring 200. The air outlets 120 can be arranged on the main shaft 100 in a regular or irregular manner. In this embodiment, considering the cooling effect, a regular arrangement is preferred to achieve temperature uniformity among the multiple slip rings 200 and maintain consistent winding tension. For example, a slitting machine divides a wide sheet of film into multiple narrow sheets and winds them up. Each slip ring 200 corresponds to one roll of narrow film. It is required that the winding tension of the multiple narrow sheets be consistent because the winding tension of the magnetically controlled slip ring will vary due to temperature differences (the effect of temperature on the magnet's magnetism). If the temperature is uneven, it will lead to inconsistent tension in the finished winding product.

[0031] A proportional solenoid valve 300 is installed between the air intake component 110 and the air source, and the proportional solenoid valve 300 is connected to the industrial control signal of the winding equipment. It should be noted that the industrial control signal of the winding equipment generally also includes information such as speed difference and temperature. Since the proportional solenoid valve 300 not only controls opening and closing but also proportionally controls the air pressure entering the vortex tube (within the air source supply pressure range), combined with the working principle of the vortex tube, it can control the airflow temperature and airflow magnitude, thereby achieving online real-time temperature control. The airflow temperature control range is from room temperature to -47°C.

[0032] Furthermore, such as Figure 3As shown, the intake component 110 includes a cold-end pipe 111, a hot-end pipe 112, a vortex chamber 113, and an air source connector 114. The cold-end pipe 111, hot-end pipe 112, and air source connector 114 are respectively connected to the vortex chamber 113. The cold-end pipe 111 is connected to the gas flow channel 130, the hot-end pipe 112 faces the outside of the main shaft 100, and the air source connector 114 is connected to an air source. Compressed gas enters from the air source connector 114, expands rapidly in the vortex chamber 113, and rotates tangentially. The rotational angular velocity of the vortex increases closer to the center. Due to the difference in angular velocity, friction is generated between the layers of the free vortex. The airflow angular velocity is the largest in the central part. As a result of friction, energy is transferred to the outer layer airflow with a lower angular velocity. The airflow in the central layer loses energy, has low kinetic energy, reduces speed, and lowers temperature. It is then led out from one end through the orifice plate in the center of the vortex pipe to obtain the cold airflow required for cooling. It has the characteristics of small size, light weight, no spark generation, and rapid cooling.

[0033] like Figure 4 As shown, when the volume of the main shaft 100 is large enough, the air intake component 110 is integrated into the main shaft 100, that is, a receiving cavity is provided in one end of the main shaft 100, and the air intake component 110 is disposed in the receiving cavity. Similarly, the air intake component 110 does not rotate together with the main shaft 100, and the two are directly connected through a rotary joint.

[0034] Furthermore, the air outlets 120 on the main shaft 100 are divided into several groups, with each group having several air outlets 120. The air outlets 120 in the same group are circumferentially distributed on the main shaft 100. That is, if there are three air outlets 120 in each group, the three air outlets 120 are divided by 120°. If there are four air outlets 120 in each group, the three air outlets 120 are divided by 90°, and so on.

[0035] Furthermore, such as Figure 5 As shown, based on multiple sets of air outlets 120, starting from the air inlet component 110, the area of ​​each set of air outlets 120 gradually increases towards the farthest set of air outlets 120. Since the air source is located at the end, if all air outlets 120 are the same size (or the sum of the areas of each set of air outlets 120 is the same), the air pressure at the far end of the air outlet 120 will inevitably be lower than that at the near end, which will result in lower cooling efficiency of the slip ring 200 at the far end. Considering the uniformity of temperature control, this problem can be solved by adjusting the interval between each set of air outlets 120 and / or adjusting the opening area.

[0036] Furthermore, with the distance between each group of air outlets 120 being equal, each group of air outlets 120 corresponds one-to-one with the same number of slip rings 200, that is, each group of air outlets 120 corresponds to one slip ring 200, thereby improving the cooling effect.

[0037] Embodiment two of this utility model, such as Figure 4 As shown, unlike Embodiment 1, the air intake component 110 is externally mounted on the spindle 100, and the air intake component 110 is connected to the gas flow channel 130 via an air pipe. This embodiment is suitable for spindles 100 with a smaller volume. When the spindle 100 is not robust enough to house the air intake component 110 internally, the air intake component 110 can be externally mounted on the spindle 100, either through direct connection or indirect connection via an air pipe.

[0038] Embodiment three of this utility model, such as Figure 6 As shown, unlike Embodiment 1, under the premise that all air outlets 120 are the same size (or the sum of the areas of each group of air outlets 120 is the same), starting from the air inlet component 110, the distance between two adjacent groups of air outlets 120 gradually decreases towards the farthest group of air outlets 120. The principle and effect are the same as in Embodiment 1, both aimed at ensuring the temperature consistency of the multiple differential rings 200.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
