Description

Technical Field

[0001] This utility model relates to the technical field of winding processing equipment, and specifically to a wire feeding mechanism. Background Technology

[0002] In the manufacturing process of products such as transformers and reactors, it is necessary to wind the iron core of the product. This is typically done by winding the wire onto a spool using a winding machine.

[0003] The following problems are known in existing technologies regarding wire laying structures:

[0004] 1. In the original production process, the wire spool fixing fixture is usually installed on the wire shaft for winding. During equipment operation, the wire may jump around in an unpredictable manner, which poses a risk of injury.

[0005] 2. Copper wires are heavy, making them inefficient and inconvenient to handle.

[0006] 3. Because the overall length of the winding on the spool is relatively long and the quality of the wire is unstable, problems such as wire knotting are prone to occur during the winding process. Utility Model Content

[0007] The purpose of this utility model is to provide a wire feeding mechanism to address the shortcomings of the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A wire feeding mechanism includes a bracket and a wire bearing mounting fixture, the wire bearing mounting fixture comprising:

[0010] Cylinder: The cylinder forms a cylinder cavity, and a top cover is formed on the top of the cylinder cavity. A cable outlet hole is provided on the top cover; the cylinder is disposed inside the bracket.

[0011] Bollard: Located inside the cavity of the cylinder, the bollard is wound with the wire to be wound;

[0012] Guide assembly: mounted on the bracket, comprising two felt boards connected by a fastener, with a wiring gap formed between the two felt boards.

[0013] In the technical solution, the wire bearing mounting fixture is mounted on the bracket for easy movement; the wire spool of the wire feeding mechanism is wrapped inside the cylinder to prevent the spool from shaking; the lateral runout of the wire can be limited; the guide component adopts a cleaning felt device, which guides the winding direction through the guide component; the felt plate can clean the stains or metal burrs on the wire, and can also prevent the wire from knotting, thereby improving the winding quality.

[0014] In some embodiments of this application, the guide assembly further includes a fixing plate, and the fixing member passes sequentially through the fixing plate and the two felt plates to fix the felt plates on the fixing plate.

[0015] In the current technical solution, the felt assembly has low flexibility and is inconvenient to fix, while the winding speed is relatively fast, which can easily lead to unstable winding. To solve this problem, a rigid fixing plate was designed to fix the felt board to the rigid fixing plate. The rigid fixing plate supports the felt board and stabilizes the winding guide structure.

[0016] In some embodiments of this application, the top cover is provided with multiple cable outlet holes, and the multiple cable outlet holes form different opening sizes.

[0017] In the technical solution, different product models have different winding requirements; some products may require thicker windings, while others may require thinner windings. By designing wire exit holes of different sizes, the problem of wire exit for different winding sizes can be solved.

[0018] In some embodiments of this application, the top of the top cover has a flat plate structure, and the cable outlet is located at the location of the flat plate structure.

[0019] In the technical solution, the overall conical shape of the top cover can better regulate the wire exit, but it is not easy to set the exit hole at the top of the cone. Based on this, the top of the top cover is made into a flat structure, which facilitates the setting of the exit hole.

[0020] In some embodiments of this application, a sleeve is installed at the outlet hole.

[0021] In this technical solution, a sleeve is installed at the cable outlet to prevent damage to the guide hole caused by high temperatures generated during high-speed cable movement. The sleeve can be made of ceramic material, which is low in cost and easy to replace.

[0022] In some embodiments of this application, the top cover is conical, and tapers in a conical shape from the top of the cylindrical cavity toward the top of the top cover.

[0023] In the technical solution, since the top cover is located at the outlet of the cable, the conical top cover forms a relatively constricted structure along the direction of the cable outlet, which facilitates the cable routing.

[0024] In some embodiments of this application, the guide assembly further includes a support rod mounted on the bracket, and the guide assembly is mounted on the support rod.

[0025] In the technical solution, a support rod structure was further designed to facilitate the installation of the guide components.

[0026] In some embodiments of this application, the height of the guide assembly located on the support rod is higher than the height of the top of the top cover.

[0027] In this technical solution, the guide assembly serves to guide the winding direction. Since the bracket is relatively low, while transformers or reactors may be placed at relatively high positions, setting the guide assembly at a higher height solves the problem of guiding the winding direction.

[0028] In some embodiments of this application, multiple sets of linear bearing carrier fixtures are arranged on the bracket, and each set of linear bearing carrier fixtures corresponds to a set of the guide components.

[0029] In the technical solution, by setting up multiple sets of wire bearing support fixtures, multiple sets of winding can be configured for the wire feeding mechanism. After one set of winding is used up, another set of winding can be replaced in time. Alternatively, different sets of winding fixtures can be configured with windings of different thicknesses for convenient use.

[0030] In some embodiments of this application, the bottom of the bracket is provided with casters.

[0031] In the technical solution, casters are installed at the bottom of the bracket to facilitate the movement of the bracket, which in turn facilitates the movement of the wire feeding mechanism, so as to facilitate the winding work of the product.

[0032] Compared with the prior art, the technical advantages of the wire feeding mechanism provided by this utility model are as follows:

[0033] The spool is mounted on the bracket for easy movement; the spool is installed inside the cylinder and the wire exits through the outlet hole, which can prevent excessive movement of the spool during high-speed winding; a felt sheet is designed to serve as a guide and deburr, which can prevent the wire from getting tangled during movement and improve winding quality and efficiency.

They 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. Therefore, they should not be construed as limitations on this utility model.

[0052] The terms "first" and "second" are used for descriptive purposes only and are not intended to imply relative importance.

[0053] In the existing technology, during the processing of products such as transformers and reactors, it is necessary to wind the iron core of the product, and the winding process requires the use of a wire-laying mechanism.

[0054] This application provides a wire feeding mechanism for assisting in the winding process of products such as transformers and reactors.

[0055] refer to Figures 1 to 3 This is an exemplary implementation structure of the wire laying structure provided in the embodiments of this application.

[0056] The wire feeding structure consists of two parts: a bracket 1 and a wire bearing fixture. The wire bearing fixture is the main part that carries the winding wire and is mounted on the bracket 1.

[0057] The linear bearing load-bearing fixture includes a cylinder 2, a linear spool 3, and a guide assembly 4.

[0058] The cylinder 2 is mounted on the bracket 1. The main body of the cylinder 2 forms a cylinder cavity 201. In this embodiment, the cylinder 2 is cylindrical in shape, forming a cylindrical cylinder cavity 201.

[0059] The spool 3 has the wire to be wound on it, and the spool 3 is located inside the cylindrical cavity 201. It should be understood that the cylindrical cavity 201 serves as the housing space for the spool, and adopts a cylindrical structure to enclose the spool inside, which can limit the lateral runout of the wire.

[0060] A top cover 202 is formed at the top of the cylindrical cavity 201. A wire outlet hole 203 is provided on the top cover 202, through which the wire wound on the spool 3 passes for winding. The top cover 202 and the main body of the cylindrical cavity 2 can be designed as a detachable structure for easy replacement of the spool 3. The cylindrical cavity 2 and the spool 3 are made entirely of engineering plastic, making them lightweight and easy to handle.

[0061] To facilitate the installation of the bobbin, a bobbin post 204 is provided at the bottom of the cylinder cavity 201, and the bobbin 3 is mounted on the bobbin post 204.

[0062] The guide assembly 4 is used to guide the direction of the winding. It is mounted on the bracket 1 and includes two felt plates 401. The felt plates 401 are connected by a fastener 402. A winding gap is formed between the two felt plates 401, that is, the gap between the two felt plates 401 allows the winding to pass through.

[0063] The wire feeding structure provided in this application embodiment has a wire bearing mounting fixture mounted on a bracket 1. The wire bearing mounting fixture can be moved to the winding station by moving the bracket 1, which facilitates movement. The wire spool 3 of the wire feeding mechanism is wrapped inside the cylinder. The compatibility between the wire spool 3 and the cylinder cavity 201 can be improved by designing the size of the cylinder cavity 201, avoiding the spool 3 from shaking, limiting the lateral runout of the wire, and ensuring that the winding work can be carried out stably. The guide component adopts a cleaning felt device, which guides the winding direction. The winding passes through the gap between the felt plates 401. Through the friction between the winding and the felt plates 401, the function of cleaning stains or metal burrs on the wire can be achieved, thereby improving the winding quality.

[0064] In some embodiments of this application, considering the low flexibility of the felt assembly and its inconvenience in fixing, and the relatively fast winding speed, unstable winding is likely to occur. (See reference...) Figure 5 To address this issue, the guide assembly also includes a fixing plate 403, which employs a rigid structure, such as a steel plate. Compared to the felt plate 401, the fixing plate 403 offers higher stability and assists in fixing the wiring direction. The fastener 402 passes sequentially through the fixing plate 403 and the two felt plates 401 to secure the felt plates 401 to the fixing plate 403.

[0065] In the technical solution, the felt board 401 is fixed on the rigid fixing plate 403, and the rigid fixing plate supports the felt board to stabilize the wiring guide structure.

[0066] In some embodiments of this application, the top cover 202 is provided with a plurality of cable outlet holes 203, and the plurality of cable outlet holes 203 form different opening sizes.

[0067] In the technical solution, different product models have different winding requirements. For example, some large-sized products may require thicker windings, while some small-sized products may require thinner windings. Here, "large-sized" and "small-sized" refer to the diameter of the winding. If a small-sized winding passes through a large-sized exit hole 203, it will cause unstable wiring. If a large-sized winding passes through a small-sized exit hole 203, it cannot be guaranteed that the winding will pass smoothly. This application embodiment solves the problem of different sized winding exits by designing exit holes 203 of different sizes.

[0068] For example, in some embodiments of this application, the cable outlet 203 includes five outlets, including a central cable outlet arranged in the center, and edge cable outlets arranged around the central cable outlet. Figure 4 As shown, the center wire exit hole is larger in size and is suitable for thicker windings, while the edge wire exit holes are smaller in size and are suitable for thinner windings.

[0069] In some embodiments of this application, a sleeve 6 is installed at the outlet hole 203.

[0070] In the technical solution, a sleeve 6 is installed at the cable outlet to prevent damage to the guide hole caused by high temperatures generated during high-speed cable movement. The sleeve 6 can be made of ceramic material, which is low in cost and easy to replace.

[0071] In some embodiments of this application, the top of the top cover 202 has a flat plate structure, and the cable outlet 203 is located at the location of the flat plate structure.

[0072] In the technical solution, the top cover 202 is generally conical to better regulate the wire exit, but it is not easy to set the exit hole 203 at the top of the cone. Based on this, the top of the top cover 202 is made into a flat plate structure to facilitate the setting of the exit hole 203.

[0073] In some embodiments of this application, the top cover 202 is conical, and it tapers from the top of the cylinder cavity 201 to the top of the top cover 202. Since the top cover 202 is located at the cable outlet, the conical top cover 202 forms a relatively tapered structure along the cable outlet direction, which facilitates cable routing and avoids excessive shaking of the cable.

[0074] To address the installation issue of the guide assembly, in some embodiments of this application, the guide assembly further includes a support rod 6, which is mounted on the bracket 1, and the guide assembly is mounted on the support rod 6. Specifically, the support rod 6 is a straight steel rod, vertically mounted on the bracket 1. To improve the fixing effect of the support rod 6, a reinforcing member is provided between the support rod 6 and the bracket 1. In this embodiment, the support rod 6 includes a vertical rod and a horizontal rod, the guide assembly is mounted on the vertical rod, and the horizontal rod is mounted to the bracket 1. A reinforcing member 8 is provided between the vertical rod and the horizontal rod.

[0075] In some embodiments of this application, when the guide assembly is installed on the support rod 6, the height of the guide assembly is higher than the height of the top of the top cover 202. The guide assembly serves to guide the winding direction, as the bracket 1 is relatively low, while transformers or reactors may be placed at relatively high positions. Setting the guide assembly at a higher height solves the problem of guiding the winding direction.

[0076] In some embodiments of this application, to avoid frequent replacement of the bobbins, multiple sets of bobbins can be provided on the bracket 1. Specifically, the wire feeding mechanism includes multiple sets of bobbin bearing support fixtures arranged on the bracket 1, and each set of bobbin bearing support fixtures corresponds to a set of guide components.

[0077] Reference Appendix Figure 1 and Figure 2As shown, this embodiment includes two wire bearing support fixtures, namely two cylinders 2, each containing a spool 3. The two spools 3 can use wires of the same or different sizes, facilitating the use and replacement of the wires.

[0078] In the technical solution, by setting up multiple sets of wire bearing support fixtures, multiple sets of winding can be configured for the wire feeding mechanism. After one set of winding is used up, another set of winding can be replaced in time. Alternatively, different sets of winding fixtures can be configured with windings of different thicknesses for convenient use.

[0079] In some embodiments of this application, the bottom of the bracket 1 is provided with casters 5. By providing casters 5 at the bottom of the bracket 1, it is convenient to move the bracket 1, and thus convenient to move the wire feeding mechanism, so as to facilitate the winding work of the product.

[0080] When using the wire feeding mechanism provided in this application for winding work, select a suitable size of wire and replace the spool 3. Move the bracket 1 to the position of the winding table, pass the wire end through the wire outlet hole 203 of a suitable size to the outside of the cylinder 1, and wrap the wire end around the product. Start the winding equipment to wind the wire.

[0081] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
