Description

Technical Field

[0001] This utility model relates to the technical field of belt reel changing devices, and in particular to a tensioning quick-change belt reel device. Background Technology

[0002] During the operation of coil winding equipment, it is necessary to change the reel. The existing reel changing device has an extremely cumbersome operation process. When changing the reel, workers often need to go through multiple complicated steps, such as first unlocking multiple parts of the reel, then carefully removing the old reel, then accurately positioning and installing the new reel, and finally performing a series of tightening and debugging work.

[0003] Existing pulley changing devices, especially in actual operation where frequent changes are required, present the following problems:

[0004] The reel replacement process consumes a significant amount of time, greatly reducing the overall efficiency of the equipment. This not only severely impacts production schedules but also results in substantial time costs for the company. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology in that the replacement of belt reels is time-consuming, and to provide a tensioning quick-change belt reel device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] This utility model provides a tensioning quick-change belt reel device, comprising:

[0009] The tensioning core is cylindrical, and an adjustment groove is provided on the tensioning core at a position corresponding to the elastic claw in the circumferential direction. The bottom of the adjustment groove is closer to the axis of the tensioning core in the circumferential direction from one end to the other. The difference between the diameter of the tensioning core and the closest point between the bottom of the adjustment groove and the axis of the tensioning core is greater than the thickness of the elastic claw.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used 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. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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.

[0022] like Figures 1 to 2 As shown, this utility model discloses a tensioning quick-change reel device, which includes a reel mandrel and a tensioning core 2. The reel mandrel includes a fixing seat 11 for fixing to a coil winding device and at least two elastic claws 12 fixed to the fixing seat 11 for hooking the reel. The tensioning core 2 is cylindrical, and an adjustment groove 21 is provided on the tensioning core 2 at a position corresponding to the elastic claws 12 in the circumferential direction. The bottom of the adjustment groove gets closer to the axis of the tensioning core 2 in the circumferential direction from one end to the other. The difference between the diameter of the tensioning core 2 and the closest point between the bottom of the adjustment groove and the axis of the tensioning core 2 is greater than the thickness of the elastic claws 12.

[0023] With the above structure, the adjusting groove 21 is used to engage the elastic claw 12 to adjust the tension of the belt reel. During installation, the belt reel is placed on the elastic claw 12, at which point the elastic claw 12 does not grip the belt reel. Since the gap between the bottom of the adjusting groove and the axis of the tensioning core 2, which is closest to the axis of the tensioning core 2, and the belt reel is the widest, the adjusting groove is aligned with the elastic claw 12 and inserted between the elastic claws 12, and then the tensioning core 2 is rotated. During the rotation, under the action of the adjusting groove, the elastic claw 12 deforms outward, and the elastic claw 12 tightens and grips the locking belt reel.

[0024] With the above structure, during the disassembly and assembly process, the disc can be disassembled and assembled simply by rotating the tensioning core 2. The process is simple, time-saving, and efficient.

[0025] To improve the locking effect of the reel, the elastic claw 12 includes an elastic piece 121 fixed at one end to the fixing base 11 and a hook 122 disposed at the other end of the elastic piece 121. With this structure, after the reel is locked, the hook 122 is placed at the end of the reel to achieve locking, thereby improving stability.

[0026] To facilitate the installation of the tensioning core 2 into the elastic claw 12, an inclined guide structure 123 is provided on the other end of the elastic piece 121 near the axis of the fixed base 11.

[0027] The fixing seat 11 is used to fix the coil winding equipment. It has various structures. Preferably, the fixing seat 11 is disc-shaped, and the elastic claws 12 are evenly arranged around the axis of the fixing seat 11.

[0028] The mounting base 11 is used to fix the coil winding equipment. There are many ways to fix it to the coil winding equipment. In order to simplify the fixing structure, the mounting base 11 is provided with fixing holes 13. With this structure, the mounting base can be directly fixed to the rotating output shaft of the coil winding equipment through the fixing holes.

[0029] There must be at least two flexible claws, such as 2, 3, 4, 5, or 6.

[0030] For example, such as Figure 1 As shown, this is an example of setting 4 elastic claws 12. In this case, 4 adjusting grooves 21 are set upward around the tensioning core 2.

[0031] With any of the above structures, two bosses can be provided on the tensioning core 2 to facilitate operation. The bosses can serve as the operating parts for rotating the tensioning core 2, facilitating manual assembly and disassembly.

[0032] For example, such as Figure 2 As shown, four adjustment slots 21 are provided, two of which are respectively set to correspond to the positions of the two bosses.

[0033] With the above structure, the locking and unlocking of the pulley can be achieved by rotating the tensioning core 2. Compared with the existing device, the time for each pulley replacement is reduced from an average of 5 minutes to 1 minute, improving manual efficiency by nearly 80% and achieving the goal of quick pulley replacement.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
