Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically to a rotary disc assembly, a winding device, and a dual-station fully automatic winding machine. Background Technology

[0002] During the winding process of sensitive strip materials (such as adhesive films and optical films), quality problems such as misalignment and uneven winding often occur. Specifically, in the initial stage when the roll diameter is small, the material can be neatly wound on the mandrel; however, as the roll diameter increases, due to the flexibility and uneven tension distribution of the material itself, a "core pulling" phenomenon easily occurs—that is, the inner layer material is pulled and displaced by the outer layer, causing the originally neatly arranged interlayer structure to become disordered, ultimately forming an irregular roll shape. This phenomenon not only affects the appearance quality of the roll material, but may also cause problems such as deviation, tape breakage, and poor bonding in subsequent processing.

[0003] To address this issue, currently widely used single-station winding machines typically employ manual loading and unloading, and can be equipped with baffles at both ends of the mandrel. These mandrels with baffles at both ends effectively limit the axial displacement of the material, preventing uneven winding due to core pulling, thus ensuring winding quality. However, with increasing demands for production efficiency, more and more companies are introducing new types of flip-type dual-station winding machines with higher levels of automation, capable of automatically winding, wrapping, and changing rolls without stopping the machine.

[0004] However, in the new type of flip-type dual-station winding machine, the mandrel with baffles at both ends is difficult to apply directly. This is because in this type of equipment, the automatic winding mechanism is usually located on one or both sides of the winding shaft and requires a certain amount of space to operate. If ordinary baffles are installed at both ends of the mandrel in advance, it will cause spatial interference with the automatic winding mechanism, resulting in the inability to complete the winding action normally. In addition, adding a step of manually installing baffles after each winding and stopping the machine can solve the subsequent winding quality problem, but this method disrupts the rhythm of continuous production, increases the manual intervention, is cumbersome, time-consuming and labor-intensive, and greatly reduces the automation level and overall efficiency of the equipment.

[0005] In summary, to achieve fully automated winding, wrapping, and roll changing, existing reversible dual-station winding machines lack a baffle structure on the winding mandrel. For tension-sensitive and easily deformable materials, this easily leads to defects such as uneven winding and interlayer misalignment, affecting product quality. Therefore, how to achieve effective edge control of sensitive strips during automatic winding without affecting the automatic wrapping function has become a critical technical challenge that new reversible dual-station winding machines urgently need to overcome. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the prior art and provide a rotary disk assembly, a winding device and a dual-station fully automatic winding machine, which can solve the problems of uneven winding of sensitive strips and interlayer misalignment in the existing flip-type dual-station winding machine.

[0007] To achieve the above and other objectives, this utility model is implemented through the following technical solution: As a first aspect, this utility model proposes a rotating disk assembly, comprising: a rotating disk; a baffle assembly, which is telescopically disposed on the end face of the rotating disk facing the winding mandrel and coaxially disposed with the winding mandrel; and a driving device, the fixed end of which is disposed on the end face of the rotating disk facing away from the winding mandrel, and the movable end passing through the through hole of the rotating disk and connected to the baffle assembly, for driving the baffle assembly to perform telescopic movement to move away from or closer to the rotating disk.

[0008] In one embodiment, the baffle assembly includes a connecting seat and a take-up baffle, the connecting seat being fixedly connected to the guide shaft and the movable end of the drive device respectively, and the take-up baffle being rotatably mounted on the connecting seat.

[0009] In one embodiment, the inner diameter of the take-up baffle is less than or equal to the inner diameter of the connecting seat.

[0010] In one embodiment, the drive device is provided with a displacement detection device for detecting the position of the winding baffle.

[0011] In one embodiment, the baffle assembly further includes a guide shaft, one end of which is fixed to the connecting seat and the other end is slidably mounted on the linear bearing of the rotating disk.

[0012] In one embodiment, an annular guide rail is provided on one end of the take-up baffle facing the connecting seat, and a track is provided on its inner wall surface; a plurality of rollers are provided on one end of the connecting seat facing the take-up baffle, and the rollers are rotatably mounted on the track of the annular guide rail.

[0013] In one embodiment, the winding baffle and the annular guide rail are integrally formed.

[0014] In one embodiment, the plurality of rollers are arranged in a circular array.

[0015] As a second aspect, the present invention provides a winding device comprising a rotating disk assembly as described in the first aspect.

[0016] As a third aspect, this utility model proposes a dual-station fully automatic winding machine, including the winding device as described in the second aspect.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model adds a retractable baffle assembly to the rotary table of the original flip-type dual-station fully automatic winding machine. During automatic winding, the drive device drives the baffle assembly to automatically extend away from the rotary table according to the material size to form a retaining edge structure at both ends of the winding mandrel, ensuring the quality of the winding. During automatic wrapping, the drive device drives the baffle assembly to retract and approach the rotary table, away from the winding mandrel and to make enough operating space for the automatic wrapping mechanism. Thus, effective retaining edge control of the strip material is achieved during automatic winding without affecting the automatic wrapping function, resulting in a high degree of automation.

[0019] 2. The winding baffle of this utility model is rotatable, which can reduce the friction between the material and the winding baffle during winding;

[0020] 3. The winding baffle of this utility model can be flipped together with the material until the material is wound up and then retracted into the baffle assembly, which can ensure that the material will not be pulled out from the time of winding to the time of unwinding.

[0021] 4. The design of the displacement detection device of this utility model allows the position of the baffle assembly to be precisely adjusted according to materials of different widths, making it highly versatile;

[0022] 5. The design of the guide shaft on the baffle assembly of this utility model can provide linear guidance for the telescopic movement of the baffle assembly, thereby improving the operational stability of the telescopic movement;

[0023] 6. The ring guide rail design on the take-up baffle of this utility model, together with the rollers, allows the take-up baffle to rotate flexibly. Moreover, the ring guide rail is relatively thin, which can save the installation space between the take-up baffle and the connecting seat. Attached Figure Description

[0033] (Example 1)

[0034] like Figure 1-3 As shown, this embodiment provides a rotary disk assembly, including a rotary disk 10, a baffle assembly 20, and a drive device 30; the rotary disk 10 is a circular disk with two workstations, namely, two winding mandrel mounting seats 13; please refer to... Figure 4The baffle assembly 20 is telescopically mounted on the end face of the rotating disk 10 facing the take-up mandrel A, and is coaxially mounted with the take-up mandrel mounting base 13 and the take-up mandrel A. The drive device 30 can be an electric push rod, a hydraulic cylinder, a pneumatic cylinder, etc. Its fixed end (e.g., the drive motor of the electric push rod) is located on the end face of the rotating disk 10 facing away from the take-up mandrel A. Specifically, the fixed end is fixedly mounted on the rotating disk 10 through the fixing base 14, and its movable end (i.e., the push rod) passes through the through hole 11 of the rotating disk 10 and is connected to the baffle assembly 20, which is used to drive the baffle assembly 20 to perform telescopic movement to move away from or closer to the rotating disk 10.

[0035] The drive device 30 is electrically and signal-connected to the control module of the dual-station fully automatic winding machine, and can automatically drive the baffle assembly 20 to extend and retract according to the working status of the dual-station fully automatic winding machine. Specifically, when the dual-station fully automatic winding machine is automatically winding, the drive device 30 drives the baffle assembly 20 to automatically extend away from the rotary disk 10 according to the material size to form a retaining edge structure at both ends of the winding mandrel A, ensuring the quality of the winding and forming. When the dual-station fully automatic winding machine is automatically wrapping, the drive device 30 drives the baffle assembly 20 to automatically retract and approach the rotary disk 10, away from the winding mandrel A, and to make room for the automatic wrapping mechanism. This achieves effective retaining edge control of the strip material during automatic winding without affecting the automatic wrapping function, resulting in a high degree of automation.

[0036] Specifically, such as Figure 2 As shown, the guide plate assembly 20 includes a take-up guide plate 21, a connecting seat 22, and a guide shaft 23. Both the take-up guide plate 21 and the connecting seat 22 are annular structures to facilitate the installation of one end of the take-up mandrel A through the guide plate assembly 20 onto the take-up mandrel mounting seat 13. Specifically, the inner diameter of the take-up guide plate 21 can be less than or equal to the inner diameter of the connecting seat 22. The connecting seat 22 is fixedly connected to the movable end of the drive device 30, and the take-up guide plate 21 is rotatably mounted on the connecting seat 22. One end of the guide shaft 23 is fixed to the connecting seat 22, and the other end is slidably mounted on the linear bearing 12 of the rotating disk 10, thereby allowing the drive device 30 to drive the take-up guide plate 21 to extend and retract along the guide shaft 23. The design of the guide shaft 23 provides linear guidance for the extension and retraction movement of the take-up guide plate 21, improving the operational stability of the extension and retraction movement.

[0037] It should be noted that in this embodiment, the winding baffle 21 is designed as a rotatable structure, which can reduce the friction between the material and the winding baffle 21 during winding, and allow the winding baffle 21 to rotate with the material until the material is wound up before retracting the baffle assembly 20. This ensures that the material will not be pulled apart from the time of winding to the time of unwinding, which can further improve the winding and forming quality. Specifically, in this embodiment, the rotatable installation method of the winding baffle 21 and the connecting seat 22 is as follows: an annular guide rail 24 is provided on one end of the winding baffle 21 facing the connecting seat 22. The annular guide rail 24 can be integrally formed with the winding baffle 21, and a track 241 is provided on the inner wall surface of the annular guide rail 24; multiple rollers 25 are provided on one end of the connecting seat 22 facing the winding baffle 21. The multiple rollers 25 are distributed in a circular array, and the rollers 25 are rolled on the track 241 of the annular guide rail 24. The annular guide rail 24 and multiple rollers 25 work together to allow the take-up baffle 21 to rotate flexibly. The annular guide rail 24 is relatively thin, which can save installation space between the take-up baffle 21 and the connecting seat 22.

[0038] Furthermore, to improve the accuracy of the drive device 30 in positioning the winding guide plate assembly 20 and enhance its adaptability to materials of different widths, a displacement detection device, such as an electronic ruler or displacement sensor, connected to the drive device 30 via a signal connection can be installed on the drive device 30 to detect the position of the winding guide plate 21. Specifically, the displacement detection device can be located on the movable end (i.e., the push rod). When the displacement detection device detects that the winding guide plate 21 has moved to a preset working position, the drive device 30 stops driving.

[0039] It should be noted that, as Figure 3 As shown, a flipping drive device 15 is also installed on the end face of the rotary disk 10 facing away from the winding mandrel A. In this embodiment, the flipping drive device 15 is a sprocket drive device, but in other embodiments it can be other known drive structures. In addition, since the flipping drive device 15, angle sensor and other components are all conventional structures of the rotary disk assembly in a dual-station fully automatic winding machine, they are known to those skilled in the art and are not improvements of this utility model, the specific structures of other components will not be described here.
