Description

Technical Field

[0001] This utility model belongs to the field of material roll fixing technology, specifically relating to an adaptive core fixing device and a moving mechanism. Background Technology

[0002] In the production process of tweeter dome tweeters, a backing paper is needed to support the finished dome tweeter. The backing paper exists in the form of a strip, and after the backing paper is wound, a core is used as the support carrier for the wound strip.

[0003] In the production process of dome, both workshop production and manual inspection involve the replacement of materials for cores of different sizes. Traditional core fixing is generally done by using a matching tray. After placing the core on the tray, the core is fixed to the tray by installing clips on the tray. However, when mass-producing domes of different specifications, the width of the base paper used is different, and the diameter of the matching core is different. Therefore, the size of a single material tray cannot be adapted to the diameter of multiple cores. This means that the size of the material tray needs to be changed frequently and the installation position of the clips needs to be adjusted. This operation is cumbersome and greatly affects the production efficiency of the domes.

[0004] Therefore, an adaptive core fixing device and moving mechanism are designed to solve the technical problem in the existing technology that a single material tray cannot adapt to cores of various diameters, which affects the production efficiency of dome.

[0029] Research has revealed that during dome production, both workshop production and manual inspection involve changing materials for cores of different sizes. Traditionally, cores are fixed using matching trays. After placing the core on the tray, clips are installed to secure it. However, when mass-producing domes of different sizes, the width of the base paper varies, and the diameter of the matching cores differs. Therefore, a single tray size cannot accommodate multiple core diameters, requiring frequent changes to the tray size and adjustments to the clip installation positions. This cumbersome operation significantly impacts dome production efficiency.

[0030] Based on the above research, this disclosure provides an adaptive core fixing device and moving mechanism. By setting a central shaft in the center of the material tray and a driving mechanism at the top of the central shaft, cores of different diameters are sleeved on the outside of the central shaft. The driving mechanism drives the contacting parts in the moving mechanism to slide in the grooves opened on the upper surface of the material tray until they contact the inner wall of the core, thereby fixing the core on the material tray. The moving distance of each contacting part can be adjusted according to the diameter of the current core, so as to satisfy the requirement of fixing cores of different diameters on the material tray without changing the material tray, saving the time of changing the material tray and the buckle, and improving the production efficiency of the dome.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] 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.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] In some embodiments, such as Figure 1 As shown, the device has a three-dimensional structure, including a material tray 1, a central shaft 10, a drive mechanism 2, and a moving mechanism 3. The material tray 1 serves as a basic platform, with the central shaft 10 inserted into its center. The central shaft 10 passes through the material tray 1 and is connected to it through a bearing, allowing the material tray to rotate around the central shaft 10. The drive mechanism 2 is sleeved on the outer wall of the central shaft 10 and located above the material tray 1. It includes a top cover 20 (the function of the top cover 21 is to prevent the sliding disk 21 from sliding off the central shaft 10), a sliding disk 21, a star-shaped connector 22, and other components, which are used to control the movement of the moving mechanism 3. The moving mechanism 3 is set on the upper surface of the material tray 1 and consists of several circumferentially arranged abutment members 30. Each abutment member 30 slides on the surface of the material tray 1 through a sliding groove 11. Initially, the operator holds the sliding disk 21 in the upper position, at which point the contact part 30 is in close contact with the central axis 10, reserving the maximum space for the placement of the core 4. This design ensures that the device occupies the least space when idle, reduces the risk of interference, and facilitates the rapid loading of the core 4. like Figure 2 As shown in the exploded view, the overall layout of the device embodies the modular design concept: the drive mechanism 2 drives the moving mechanism 3 through mechanical linkage, while the support mechanism 5 (located below the material tray 1) provides stability. Each component can be detached and connected for easy maintenance. The initial state setting not only optimizes the operation process, but also achieves "one-click" adjustment through the up and down movement of the sliding plate 21, avoiding the cumbersome steps of traditional material tray replacement. In practical applications, the operator only needs to pull or push the sliding plate 21 to trigger the entire adaptive process, which significantly improves the efficiency in the production of tweeter domes.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, when the operator begins operation, they first pull the sliding disk 21 upwards along the axis of the central shaft 10. This process is the core of the device's adaptive function, and its linkage mechanism is as follows: Figure 3As shown: The lower end face of the sliding disk 21 is fixedly connected to the upper end face of the star-shaped connector 22, and the center of the star-shaped connector 22 is provided with a sliding bearing 24. The bearing is sleeved on the outer wall of the central shaft 10, and the sliding bearing 34 passes through the sliding disk 21 simultaneously. The design of the sliding bearing 24 allows the star-shaped connector 22 to slide along the central shaft 10 axially, while reducing friction. As the sliding disk 21 moves upward, the star-shaped connector 22 moves upward simultaneously. Several protrusions 220 on its outer wall (two protrusions form a group) are connected to the corresponding moving shaft 35 through the shaft pin 23. The pin 23 acts as a rotation hub, converting the linear motion of the star-shaped connector 22 into the radial motion of the moving shaft 35. like Figure 4 As shown, the other end of the moving shaft 35 is connected to the abutment 30 via a rotating pin 34. The abutment 30 has an upward-facing C-shaped structure, and the rotating pin 34 is installed inside the opening to achieve a rotatable connection with the moving shaft 35. This design allows the moving shaft 35 to slide along the slide groove 11 with the rotating pin 34 as the fulcrum when pulled or pushed. During the initial upward movement, the moving shaft 35 is pulled inward (i.e., towards the axis of the central shaft 10), causing each abutment 30 to slide along the slide groove 11 and approach the central shaft 10. At this time, the gap between the abutment 30 and the central shaft 10 is minimized, facilitating the insertion of the core 4. After the abutment 30 is close to the central shaft, the operator places the core 4 on the upper surface of the tray 1, ensuring that the central shaft 10 passes through the inner hole of the core 4; the upper surface of the tray 1 is flush with the upper surface of the support member 31, providing stable support for the core. Subsequently, the operator pushes the sliding disk 21 in the opposite direction, causing it to move downwards. The star-shaped connector 22 then descends, pushing the moving shaft 35 outwards (i.e., away from the axis of the central shaft 10) through the pivot pin 23. The thrust of the moving shaft 35 is transmitted to the contact member 30 through the rotating pin 34, forcing the contact member 30 to slide along the slide groove 11 until its inner surface tightly contacts the inner wall of the core 4. The guiding effect of the slide groove 11 ensures the linear movement of the contact member 30 and avoids deflection. Throughout the process, the moving distance of the sliding disk 21 directly controls the displacement of the contact member 30, thereby adapting to cores 4 of different diameters. For example, small-diameter cores 4 require smaller displacements, while large-diameter cores 4 require larger displacements. The operator can precisely control the movement by touch or by scale markings (not shown) to achieve rapid fixation. This linkage mechanism not only simplifies the operation but also enhances the fixation reliability through the mechanical self-locking effect (such as the friction between the contact member 30 and the inner wall of the core), preventing the core 4 from loosening during rotation.

[0036] In some embodiments, such as Figure 4As shown, the component details of the moving mechanism 3 further ensure the stability and durability of the device. The lower end face of each contact member 30 is connected to the bearing member 31 by the first bolt 300, forming an L-shaped structure. The upper end face of the bearing member 31 is flush with the upper end face of the material tray 1. When fixing the core, it not only bears the downward pressure of the core 4, but also the lower part of the bearing member 31 is connected to the slider 32 by the second bolt 310. The slider 32 slides with the slide rail 33. The slide rail 33 is fixed in the groove 11 on the upper end face of the material tray 1, providing low resistance guidance for sliding. The slider 32 and the slide rail 33 are preferably made of wear-resistant materials (such as steel) to ensure accuracy in long-term use. When the moving shaft 35 drives the contact member 30 to move, the bearing member 31 and the slider 32 move synchronously and slide along the trajectory of the slide rail 33. This modular design facilitates maintenance and replacement, and the bolt connection allows for quick disassembly.

[0037] In some embodiments, such as Figure 5 As shown, a support mechanism 5 is provided below the material tray 1, including a base 50, an annular counterweight plate 51, and a limiting ring 53. To prevent the material tray 1 from tilting during rotation due to its large diameter, and to reduce the weight of the material tray 1, a diamond-shaped block is cut between every two sliding grooves 11 on the material tray 1. This creates several hollowed-out positions 12 on the material tray 1 to reduce its weight. Several diamond-shaped blocks are then spliced ​​together to form the base 50. A third bolt 52 connects the annular counterweight plate 51 to the base 50 through a limiting hole 510. The limiting ring 53 is fitted onto the bottom end of the central shaft 10 and fixed to the base 50 by a fourth bolt 54. The upper end face of the limiting ring 53 abuts against the lower end face of the material tray 1 to prevent the material tray 1 from directly rubbing against the annular counterweight plate 51 during rotation. The presence of the base 50 increases the contact area between the device as a whole and the worktable, thereby maintaining the overall stability of the device during high-speed rotation (such as when the bottom paper is pulled).

[0038] In some embodiments, the device's adaptive capability is achieved through... Figures 6 to 9 exhibit, Figure 6 and Figure 7 The smallest size is 4 inches. Figure 8 and Figure 9 The largest core 4 (7 inches) is achieved by adjusting the movement distance of the sliding disc 21, allowing for stepless adaptation from 4-inch to 7-inch cores without requiring any hardware replacement. After core 4 is fixed, the device enters its working state: the backing paper on the outside of core 4 is pulled manually or by a motor, causing the backing paper to rotate. At this time, the contact parts 30, the moving shaft 35, and the star-shaped connector 22 rotate around the central axis 10 via the sliding bearing 24, while the tray 1 rotates with core 4. The central axis 10 acts as a fixed axis and does not participate in the rotation, only providing support. This design reduces wear and allows for continuous production. The entire workflow requires no additional tools, significantly improving the roll changing efficiency in dome production.
