[0002] With the continuous development of the automotive industry, personalized car wheels are attracting increasing attention, and new wheel styles are constantly entering the market. Among them, plug-in wheels, with their unique styling and colorful decorative strips, are gaining popularity among young people. Plug-in wheels differ from conventional wheels in that the production process requires the installation of plug-ins after the wheel is painted, making the wheel more attractive in terms of shape and color.

[0003] The wheel hub insert installation process includes product preparation, insert placement, screw placement, screw tightening, trim strip tearing and rolling, inspection and confirmation, and stacking and shipping. During this process, workers use a handheld roller to adhere and press the strips. Manual rolling pressure is difficult to control, leading to uneven pressure, which can lead to poor consistency in the finished product and poor adhesion, affecting product quality. Furthermore, the roller can easily scratch the wheel hub paint film, resulting in product rework and reduced efficiency.

[0004] Based on this, developing a wheel hub trim strip pressing mechanism for application in actual production is an urgent problem to be solved. Utility Model Content

[0005] The purpose of the present utility model is to provide a wheel hub decorative strip pressing mechanism to address the above-mentioned problems, so as to solve the problem that the pressing force is difficult to control during the rolling operation of the wheel hub decorative strip, which easily leads to poor consistency of the rolled decorative strip product, inability to ensure the adhesive strength of the decorative strip, and easy scratching of the wheel hub paint film.

[0009] Preferably, a strip hole is provided on the wheel frame corresponding to the stop pin, and the strip hole provides a movable space for the stop pin to move forward and backward relative to the roller. The stop pin passes through the strip hole and is fixed in the stop groove.

[0010] Preferably, an adjusting tail plug is provided at the tail end of the supporting sleeve, the preload spring abuts against the adjusting tail plug, an external thread is provided on the outer diameter of the adjusting tail plug, an internal thread is provided on the inner diameter of the supporting sleeve corresponding to the external thread connection of the adjusting tail plug, and the adjusting tail plug is threadedly connected to the inner diameter of the supporting sleeve.

[0011] Preferably, the tail end of the support sleeve is connected to a telescopic cylinder, and a pressing force is applied to the roller through the telescopic cylinder.

[0012] The beneficial effects of the present invention are:

[0013] The wheel hub trim strip clamping mechanism provided by this utility model elastically connects the wheel frame to the support sleeve and uses a stop pin to limit the rotation of the roller when the clamping force is insufficient.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figure 1-4 As shown, a hub decorative strip pressing mechanism includes a support sleeve 10, to which a wheel frame 20 is elastically connected. A roller 30 for rolling the decorative strip is rotatably connected to the wheel frame 20, and a plurality of stop grooves 31 are radially provided at the end of the roller 30. A stop rod 40 is connected to the outer wall of the support sleeve 10, and a stop pin 41 is provided at the front end of the stop rod 40 corresponding to the stop groove 31 at the end of the roller 30. The stop pin 41 can be fixed in the stop groove 31 to stop the roller 30 and prevent the roller 30 from rotating to perform the rolling operation when the clamping force is insufficient.

[0022] When rolling the decorative strip, hold the support sleeve 10 and place the roller 30 on the decorative strip in preparation for rolling. At this point, the pressing mechanism is in its initial state, with the wheel frame 20 driving the elastic force of the supported sleeve 10 away from the support sleeve 10. The stop pin 41 is locked in the stop groove 31 of the roller 30, restricting the rotation of the roller 30. During rolling, press the support sleeve 10, causing the wheel frame 20 to lead the roller 30 to retract against the elastic force. At this point, the fixed stop pin 41 will gradually disengage from the stop groove 31. When the pressure reaches a certain level, the stop pin 41 will completely disengage from the stop groove 31, losing its retaining effect on the roller 30. The roller 30 will then begin to rotate and roll the decorative strip with a predetermined pressing force, completing the decorative strip tearing and pressing operation.

[0023] In this embodiment, the wheel frame 20 is elastically connected to the support sleeve 10, and the stop pin 41 is used to limit the rotation of the roller 30 when the clamping force is insufficient, effectively avoiding the problems of insufficient clamping force and uneven force during the rolling operation of the decorative strip, resulting in loose adhesion and poor consistency of the decorative strip and the roller 30 easily scratching the wheel hub paint film.

[0024] The wheel frame 20 is elastically connected to the support sleeve 10 via a connecting rod 21. Specifically, a sliding hole is formed on the support sleeve 10 corresponding to the connecting rod 21, and the connecting rod 21 is slidably connected to the sliding hole. A preload spring 11 is provided in the support sleeve 10, and the connecting rod 21 is elastically connected to the rear end of the support sleeve 10 via the spring.

[0025] Preferably, a strip hole 22 is opened on the wheel frame 20 corresponding to the stop pin 41, and the strip hole 22 provides a movable space for the stop pin 41 to move forward and backward relative to the roller 30. The stop pin 41 passes through the strip hole 22 and is fixed in the stop groove 31.

[0026] like Figure 2As shown, the tail end of the support sleeve 10 is provided with an adjustment tail plug 12, and the preload spring 11 abuts against the adjustment tail plug 12. The outer diameter of the adjustment tail plug 12 is provided with an external thread, and the inner diameter of the support sleeve 10 is provided with an internal thread corresponding to the external thread of the adjustment tail plug 12. The adjustment tail plug 12 is threaded onto the inner diameter of the support sleeve 10. By rotating the adjustment tail plug 12 for axial displacement within the support sleeve 10, the preload force of the preload spring 11 can be adjusted to meet the use requirements of different rolling pressure strengths and improve applicability.

[0027] Preferably, if Figure 4 As shown, the tail end of the support sleeve 10 is connected to a telescopic cylinder 50, which applies a pressing force to the roller 30 through the telescopic cylinder 50, further uniformizing the force on the decorative strip and ensuring the consistency of the rolling effect. At the same time, it eliminates the trouble of manual operation and reduces labor intensity.

[0028] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, any deformation made should be deemed to be protected by the present invention.
