[0002] In the production of sealing components, rubber is needed to provide auxiliary sealing. After the rubber strips are produced, they are wound and coiled. However, current winding reels, such as the utility model patent with publication number CN211769555U, disclose a rubber strip winding reel for a bonding machine, including a base and a fixing frame. The fixing frame has several horizontal branch rods distributed radially from the center on its axial side. The branch rods are connected to guide rollers for supporting the wire reel. The guide rollers extend in the same direction as the branch rods, and the outer ends of the branch rods are connected to vertically arranged limiting rollers. By having the limiting rollers slide on the guide rollers, the winding of the wire reel can be completed manually without rotating around the winding reel.

[0003] The current winding disc diameter is not adjustable, and the thicker rubber strips have a limited degree of flexibility, making it difficult to adapt to related facilities, impossible to perform winding work, occupying work space, and hindering loading work. Utility Model Content

A locking component is provided between the rotating frame and the rotating platform.

[0007] Furthermore, the rotating platform has a flange on its outer periphery facing downwards, and the flange is turned inwards to form a guide groove, into which the rotating frame is disposed.

[0008] Furthermore, the locking component includes: the guide groove has an elongated hole, the rotating frame passes through the elongated hole and is fixedly provided with a first rotating handle, the first rotating handle is provided with a sleeve handle, the sleeve handle is connected to the first rotating handle by a thread, the sleeve handle is provided with a rubber locking piece adapted to the rotating platform, and the surface of the sleeve handle is provided with a frosted surface.

[0018] 2. The use of threaded connection sleeve and rubber locking plate, as well as the design of limit teeth and locking teeth, provides a reliable locking mechanism to ensure that the rotating frame and rotating platform will not slide relative to each other during the winding process, while the rotation of the rotating platform is not affected, thus ensuring the stability and accuracy of winding.

[0019] 3. The second rotating handle makes operation simpler, and users can easily adjust the diameter by moving the first and second rotating handles relative to each other.

[0020] 4. At the same time, the sliding seats located in the arc-shaped groove and the straight groove are inlaid with ball bearings, which reduces friction during the sliding process and improves the durability and service life of the rubber strip winding disc. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0029] Example

[0030] An adjustable diameter adhesive strip winding reel includes a rotating platform 2 rotatably connected to a support 1. The rotating platform 2 has multiple straight grooves 3 arranged radially in a circular array. A flange 4 is formed on the outer periphery of the rotating platform 2, and the flange 4 is turned inward to form a guide groove 5. A rotating frame 6 rotates coaxially with the rotating platform 2, and its outer periphery can rotate along the guide groove 5. The rotating frame 6 is provided with an arc-shaped sliding groove 7. A sliding seat 8 is simultaneously disposed within both the straight grooves 3 and the arc-shaped sliding groove 7. The sliding seat 8 is rotatably connected to a limit roller 9. A locking component is provided between the rotating frame 6 and the rotating platform 2. The rotating platform 2 and the support 1, and the rotating frame 6 and the support 1, are both connected by bearings 10. The sliding seat 8 is embedded with a bearing 11, which is tangential to the rotating platform 2.

[0031] The locking component includes: a guide groove 5 with an elongated hole 12, a rotating frame 6 passing through the elongated hole 12 and fixedly mounted with a first rotating handle 13, the first rotating handle 13 being provided with a sleeve handle 14, the sleeve handle 14 being connected to the first rotating handle 13 by a thread 15, the sleeve handle 14 being provided with a rubber locking piece 16 that can tightly engage with the rotating platform 2, and the surface of the sleeve handle 14 being provided with a frosted surface. The first rotating handle 13 is axially provided with a connecting groove 17, the rotating frame is provided with a connecting piece 18 that matches the connecting groove 17, a limiting tooth 19 extending from the outer side of the connecting groove 17, and a locking tooth 20 matching the limiting tooth 19 being provided inside the flange 4, the limiting tooth 19 being vertically offset from the elongated hole 12.

[0032] The sliding seat 8 is a split structure consisting of upper and lower parts, which are fixedly connected by bolts. A second rotating handle 21 is also provided on the outer surface of the rotating platform 2. Multiple weight-reducing holes 22 are provided on the surface of the rotating platform 2. The support 1 is equipped with casters 23 for braking.

[0033] Working principle:

[0034] The user operates the first rotating handle 13 and the second rotating handle 21 to make the rotating frame 6 rotate relative to the rotating platform 2. Since the sliding seat 8 moves along the arc-shaped groove, and the straight groove 3 restricts the direction of movement of the sliding seat 8, the sliding seat 8 can only move along the radial direction of the rotating platform 2 during the movement of the sliding seat 8 along the arc-shaped groove due to the limitation of the straight groove 3, thereby realizing the adjustment of the diameter of the winding disc.

[0035] The locking components include an elongated hole 12 in the guide groove 5, a first rotating handle 13, a sleeve handle 14, a rubber locking plate 16, a limiting tooth 19, and a locking tooth 20. When locking is required, the user rotates the sleeve handle 14, which moves towards the center of the rotating platform 2 via the threaded connection 15. This causes the limiting tooth 19 to engage with the locking tooth 20, locking the rotating frame 6 and the rotating platform 2. The sleeve handle 14 and the rotating platform 2 together clamp the rubber locking plate 16, relying on the friction of the rubber locking plate 16 to achieve mutual locking between the rotating frame 6 and the rotating platform 2. At the same time, the engagement of the limiting tooth 19 and the locking tooth 20 enhances the stability of the lock. Here, the connecting groove 17 and the connecting piece 18 also prevent the sleeve handle 14 and the first rotating handle 13 from rotating together due to force, which could lead to failure and damage. When unlocking, the user rotates the sleeve handle 14 in the opposite direction, so that the limiting tooth 19 and the rubber locking piece 16 move a certain distance away from each other. Then, the user pushes the first rotating handle 13 along the limiting piece toward the center of the rotating platform 2, so that the limiting tooth 19 and the locking tooth 20 are separated, and the locking state can be released.

[0036] The sliding seat 8 is a split structure, connected by bolts for easy assembly. Multiple weight-reducing holes 22 are provided on the surface of the rotating platform 2, reducing the overall weight of the equipment. Meanwhile, the support 1 is equipped with casters 23 for braking, increasing the stability and safety of the equipment. The second rotating handle 21 simplifies operation; users can easily adjust the diameter by moving the first rotating handle 13 and the second rotating handle 21 relative to each other.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
