Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, and specifically relates to a device for adjusting the position of the rubber sheet. Background Technology

[0002] In tire manufacturing, the sidewall pressing process requires the cold-applying of one or two sidewall sheets of specific width and thickness to the outer surface of the semi-finished sidewall, according to technical specifications, to enhance the adhesion and structural strength of the sidewall area. However, during the actual bonding process, if the sidewall sheet shifts position, it will result in incomplete adhesion to the molding drum, leading to defects such as air bubbles in the misaligned area. These defects usually require manual correction by operators in subsequent processes, increasing labor intensity and affecting production efficiency. More seriously, if air bubble defects are located in the bead area and are not effectively identified and addressed before vulcanization, they may cause structural defects in the finished tire, ultimately resulting in the scrapping of the entire tire, severely impacting product quality and the company's economic benefits.

[0003] In existing technologies, tire sidewall rubber sheets are typically supplied and guided via a rubber sheet mounting frame. However, this mounting frame is usually a fixed structure and lacks the function of adjusting the lateral position of the rubber sheet. To adapt to the bonding requirements of different specifications of tire sidewall rubber sheets, production mainly relies on adjusting the position of the alignment roller or bonding roller to indirectly control the bonding position of the rubber sheet. This method has a relatively slow response speed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, an adjustable film position device is proposed to solve the technical problem that the film mounting frame in the existing technology is a fixed structure and does not have the function of actively adjusting the lateral position of the tire sidewall film, thus failing to achieve precise film positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adjustable film position device includes a film mounting frame, with a fixed baffle and a movable baffle sleeved around the periphery of the film mounting frame. The fixed baffle and the movable baffle are spaced apart to form a space for mounting the film roll. The movable baffle can move along the axial direction of the film mounting frame.

[0006] The technical solution is further configured such that the film mounting bracket has a slot extending along its axial direction, and a slider is slidably connected to the slot inside the slot, and the slider is connected to the movable baffle. The slider drives the movable baffle to slide along the slot to adjust the lateral position of the film.

[0007] The technical solution is further configured such that the end of the slider is an arc-shaped structure.

[0008] The technical solution is further configured such that a fastener is provided on the fixed baffle, and the end of the fastener abuts against the film mounting frame to lock the fixed baffle in position on the film mounting frame.

[0009] The technical solution is further configured to include an adjusting screw, the first end of which is located outside the film mounting bracket, the second end of which extends into the interior of the film mounting bracket, the adjusting screw being rotatable relative to the film mounting bracket, and a screw nut adapted to the adjusting screw being connected to the slider. When the adjusting screw is rotated, the screw nut moves along the adjusting screw axis, causing the slider and the movable baffle to move synchronously.

[0010] The technical solution is further configured such that a bearing is provided between the adjusting screw and the film mounting bracket.

[0011] The technical solution is further configured such that a mounting seat is provided at the first end of the film mounting frame, the first end of the adjusting screw passes through the mounting seat and extends to the outside of the mounting seat, and a fixing seat is provided at the second end of the film mounting frame. The technical solution further specifies that the mounting base is configured as a conical structure.

[0012] The beneficial effects of this utility model are: By setting a movable baffle that can move axially on the film mounting bracket, the lateral position of the film can be precisely adjusted, so that the film can be accurately positioned to the required position, reducing defects such as poor adhesion and air bubbles caused by positional misalignment. At the same time, the movement of the movable baffle can adjust the distance between the movable baffle and the fixed baffle to match films of different widths, improving flexibility.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] According to an embodiment of this utility model, an adjustable film position device is provided. Please refer to [link to relevant documentation]. Figures 1 to 5 The film mounting frame 1 includes a fixed baffle 2 and a movable baffle 3, which are sleeved around the periphery of the film mounting frame 1. The fixed baffle 2 and the movable baffle 3 are spaced apart to form a space for mounting film rolls. The movable baffle 3 can move along the axial direction of the film mounting frame 1.

[0018] In use, first move the movable baffle 3, then install the film roll, and finally install the fixed baffle 2. Use the fixed baffle 2 and the movable baffle 3 to limit the two sides of the film roll.

[0019] Understandably, by setting a movable baffle 3 that can move axially on the film mounting bracket 1, the lateral position of the film can be precisely adjusted, so that the film can be accurately positioned to the required position, reducing the defects of poor bonding and air bubbles caused by positional deviation. At the same time, the movement of the movable baffle 3 can adjust the distance between the movable baffle 3 and the fixed baffle 2 to match films of different widths and improve flexibility.

[0020] In one embodiment of the device for adjusting the film position, please refer to... Figures 1 to 5 The film mounting bracket 1 has a slot 6 extending along its axial direction, and a slider 10 is provided inside the slot 6 and slidably connected thereto. The slider 10 is connected to the movable baffle 3.

[0021] Furthermore, the first end of the slot 6 has an opening to facilitate the installation of the slider 10.

[0022] Understandably, the slot 6 extends axially along the film mounting bracket 1, providing a clear sliding trajectory for the slider 10. When the slider 10 slides within the slot 6, its movement is stable and well-guided, ensuring that the movable baffle 3 can only move axially (i.e., in the lateral adjustment direction), avoiding skewing or jamming. This structure ensures that the lateral position of the film can be precisely and controllably adjusted, effectively preventing film misalignment and improving bonding accuracy.

[0023] In one embodiment of the device for adjusting the film position, please refer to... Figures 1 to 5 The end of the slider 10 is designed with an arc-shaped structure. This arc-shaped end serves as a guide and self-centering mechanism. When the slider 10 is inserted into the slot 6 through the end opening, the arc-shaped structure acts like a chamfer, facilitating the smooth sliding of the slider 10 into the slot 6. This design reduces the risk of damage caused by sharp edges or scratches during assembly, improving assembly efficiency and operational safety. As the slider 10 slides along the slot 6, the contact between the end of the arc-shaped structure and the edge of the slot 6 is smoother, reducing frictional resistance and scratching, ensuring stable operation even with minor assembly deviations.

[0024] In one embodiment of the device for adjusting the film position, please refer to... Figures 1 to 5 The fixed baffle 2 is provided with a fastener 7, and the end of the fastener 7 abuts against the film mounting bracket 1.

[0025] Furthermore, both the movable baffle 3 and the fixed baffle 2 are configured as annular structures, and the annular structures are provided with a central hole that matches the longitudinal cross-sectional shape of the film mounting bracket 1.

[0026] Specifically, the annular structure includes a limiting part and a mounting part. The limiting part is used to directly contact the end face of the film roll to play an axial blocking role and prevent the film roll from axially shifting or moving during the feeding process. The mounting part is provided with mounting holes to realize the sliding or fixed cooperation between the movable baffle 3, the fixed baffle 2 and the film mounting frame.

[0027] Specifically, the longitudinal section of the film mounting bracket 1 is square, and the central hole matches its shape, forming a non-circular cross-section guide fit. This fit allows the movable baffle 3 and the fixed baffle 2 to move or be fixed axially while completely restricting their circumferential rotation relative to the film mounting bracket 1, avoiding adjustment failure or positional deviation due to rotation, and ensuring the accuracy of the adjustment position. The fastener 7 is threadedly connected to the mounting hole on the fixed baffle 2, and the end of the fastener 7 abuts against the plane, forming a dual stabilizing structure of "thread preload and end face support," which significantly improves the durability of the locking force and the vibration resistance, thereby locking the fixed baffle 2 in position on the film mounting bracket 1 and ensuring that the fixed baffle 2 does not loosen or shift during long-term operation.

[0028] In one embodiment of the device for adjusting the film position, please refer to... Figures 1 to 5 It also includes an adjusting screw 9, the first end of which is located outside the film mounting frame 1, and the second end of which extends into the interior of the film mounting frame 1. The adjusting screw 9 is rotatable relative to the film mounting frame 1, and a screw nut 11 adapted to the adjusting screw 9 is connected to the slider 10.

[0029] It is understandable that the adjusting screw 9 and the screw nut 11 form a helical transmission pair, converting rotary motion into linear motion. When the adjusting screw 9 is rotated, the screw nut 11 moves along its axial direction, driving the slider 10 and the movable baffle 3 connected to it to move synchronously.

[0030] Furthermore, a rotary handwheel 8 is provided at the first end of the adjusting screw 9, which the operator can directly rotate for adjustment.

[0031] Furthermore, a bearing 12 is provided between the adjusting screw 9 and the film mounting frame 1. Specifically, bearings 12 are provided at both the first end of the adjusting screw 9 and the second end of the film mounting frame 1. The outer ring of the bearing 12 is connected to the film mounting frame 1, and the inner ring of the bearing 12 is connected to the adjusting screw 9. The adjusting screw 9 can rotate relative to the film mounting frame 1 by providing the bearing 12.

[0032] In one embodiment of the device for adjusting the film position, please refer to... Figures 1 to 5 The first end of the film mounting frame 1 is provided with a mounting base 5, the first end of the adjusting screw 9 passes through the mounting base 5 and extends to the outside of the mounting base 5, and the second end of the film mounting frame 1 is provided with a fixing base 4. Understandably, the mounting base 4 allows the entire device to be installed onto the film laminating equipment. The mounting base 4 is integrally formed with the film mounting frame 1, possessing high mechanical strength, rigidity, and vibration resistance. It can effectively withstand the dynamic loads and film tension during equipment operation, preventing film misalignment or lamination errors caused by loose connections. The mounting base 5 is connected to the first end of the film mounting frame 1 via screws, facilitating maintenance.

[0033] Furthermore, the mounting base 5 is configured with a conical structure, the outer contour of which gradually narrows from the first end of the film mounting bracket 1 to the rotating handwheel 8, forming a smooth transition. The conical structure design helps to avoid surrounding moving parts or pipelines, optimize the internal space layout of the equipment, and avoid interference.
