Description

Technical Field

[0001] This utility model relates to the field of winding and unwinding technology, and in particular to a high-speed winding and unwinding mechanism. Background Technology

[0002] For rolled materials, the material is typically released for processing via an unwinding device and then wound back up via a rewinding device for unloading. Aside from slit materials, in most roll-to-roll material processing solutions, the rewinding and unwinding devices can be structurally identical.

[0003] In existing technologies, to improve efficiency, the winding and unwinding devices are typically equipped with a flipping action, usually with at least two stations. After unwinding / winding is completed, the station is flipped to allow the next station to continue unwinding / winding. This method is commonly used in high-speed unwinding. However, the flipping station necessitates adjustments to the drive mechanism (the mechanism controlling the rotation of the material roll shaft). The current common practice is to equip each station with a drive mechanism, or use a drive mechanism in conjunction with a clutch, so that the material roll at the station can still be driven to rotate for winding / unwinding after station switching. However, these methods have the following drawbacks: the former is mounted on a turntable, increasing the load and reducing efficiency during station switching; the latter is prone to misalignment during flipping, which can prevent the material roll from being driven. Summary of the Invention

[0004] This utility model addresses the problems of the prior art by providing a high-speed winding and unwinding mechanism, which adopts a driver for each station and eliminates the driver from the mounting base to reduce the load.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a high-speed winding and unwinding mechanism for film material winding or unwinding. It includes a machine body, mounting seats, a roller changing module, and a drive module. The roller changing module is used to drive the mounting seats to rotate and adjust the position of the film roll. The mounting seats have a rotating shaft assembly and multiple material shaft assemblies for assembling different film rolls. The drive module includes multiple drivers and multiple transmission components. The multiple drivers are all mounted on the machine body. The multiple drivers and multiple transmission components are connected in a one-to-one driving manner. The multiple transmission components are connected in a one-to-one driving manner with the multiple material shaft assemblies. The multiple transmission components are all mounted on the rotating shaft assembly.

[0006] Furthermore, the drive module also includes a bushing, which is fitted onto the rotating shaft assembly; the transmission assembly includes a first belt, a second belt, a first gear, a second gear, and a third gear, the first gear is mounted on the driver, the second gear is mounted on the bushing, the two ends of the first belt are respectively wound around the first gear and the second gear, and the two ends of the second belt are respectively wound around the second gear and the third gear.

[0007] Furthermore, the material shaft assembly consists of two parts, with the bushing including a sleeve body and a bearing structure. The sleeve body is fitted onto the rotating shaft assembly, and the bearing structure is fitted onto the sleeve body. The second gear is mounted on either the sleeve body or the bearing structure.

[0008] Furthermore, one of the transmission components has two second gears, which are mounted on the sleeve, and the bearing structure is located between the two second gears; The number of second gears in another transmission component is one, and the bearing structure includes two support bearings spaced apart in the sleeve, with the one second gear mounted on the two support bearings.

[0009] Furthermore, the material shaft assembly includes two material shafts and two telescopic joints. The two material shafts are respectively used to insert into both ends of the material roll, and the two telescopic joints are respectively used to control the connection or disconnection of the two material shafts from the material roll.

[0010] Furthermore, the telescopic device includes a telescopic cylinder, a fixed seat, and a telescopic seat. The fixed seat is installed on the machine body, the telescopic seat is movably disposed within the fixed seat, and the material shaft is installed on the telescopic seat; the number of telescopic cylinders is at least one.

[0011] Furthermore, the roller changing module includes a roller changing driver, a drive gear, and a driven gear. The driven gear is mounted on the mounting base, and the drive gear meshes with the driven gear. The roller changing driver drives the mounting base to rotate relative to the machine body through the drive gear and the driven gear. The mounting base is used to mount at least two rolls.

[0012] Furthermore, the roller changing module also includes several guide rollers, which are rotatably mounted on the machine body. The guide rollers have guide parts that are used to abut against the side of the mounting base.

[0013] Furthermore, the mounting base includes two rotating plates, which are rotatably mounted on the machine body. The rotating plates have a circular cross-sectional shape and are used to abut against the inner bottom wall of the guide section.

Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 6As shown, this utility model provides a high-speed winding and unwinding mechanism for film material winding or unwinding. It includes a machine body 1, mounting bases 2 all mounted on the machine body 1, a roller changing module 3, and a drive module 4. The roller changing module 3 is used to drive the mounting base 2 to rotate to adjust the position of the film roll. The mounting base 2 has a rotating shaft assembly 21 and multiple material shaft 221 assemblies 22 for assembling different film rolls. The drive module 4 includes multiple drivers 41 and multiple transmission components 42. The multiple drivers 41 are all mounted on the machine body 1. The multiple drivers 41 and multiple transmission components 42 are connected in a one-to-one driving manner. The multiple transmission components 42 are connected in a one-to-one manner to the multiple material shaft 221 assemblies 22. The multiple transmission components 42 are all mounted on the rotating shaft assembly 21.

[0024] In actual use, the optimal number of material shaft assemblies 221 is two. This ensures that the structure of this invention is not overly complex, thus allowing for smooth operation. Taking the winding application of this invention as an example, it also includes a guide roller module 6 and a cutting module 7. The guide roller module 6 is mainly used to guide the material onto the reel of the material shaft assembly 22 near the guide roller module 6. The material shaft assembly 22 is driven to rotate via the drive 41 and the transmission component 42 to achieve the winding effect. When the material wound on the reel reaches the required amount, the material shaft assembly 22 stops rotating. Then, the roller changing module 3 drives the mounting base 2 to rotate 180°, causing the positions of the two material shaft assemblies 22 to be swapped. This allows the reel on the other material shaft assembly 22 to wind up the material while the operator removes the material roll from the other fully loaded material shaft assembly 22 and replaces it with a new reel.

[0025] Because the driver 41 is located in the body 1, the load on the mounting base 2 is reduced. Therefore, when the mounting base 2 rotates, its rotation speed can be further increased, which is beneficial to improving the overall operating efficiency of this invention and is suitable for high-speed winding and unwinding applications.

[0026] In this embodiment, the drive module 4 further includes a bushing 43, which is fitted onto the rotating shaft assembly 21; the transmission assembly 42 includes a first belt 421, a second belt 422, a first gear 423, a second gear 424, and a third gear 425. The first gear 423 is mounted on the driver 41, the second gear 424 is mounted on the bushing 43, the two ends of the first belt 421 are respectively wound around the first gear 423 and the second gear 424, and the two ends of the second belt 422 are respectively wound around the second gear 424 and the third gear 425.

[0027] The rotating shaft assembly 21 serves as the axis of rotation for the entire mounting base 2. Therefore, using the rotating shaft assembly 21 as the intermediate mounting part for driving ensures that the position of the transmission assembly 42 will not change too much during the rotation of the mounting base 2. To ensure that the operation of the transmission assembly 42 does not affect the rotating shaft assembly 21, this invention provides a bushing 43 for mounting the second gear 424. A structure such as a bearing can be provided between the bushing 43 and the rotating shaft assembly 21, so that the relative rotation between the bushing 43 and the rotating shaft assembly 21 will not interfere with each other, making the structure of this invention simple and ingenious.

[0028] The driver 41 is preferably mainly composed of a motor, or a motor and a reducer. Each driver 41 independently drives a material shaft assembly 22 to rotate. When one material shaft assembly 22 is winding, the other material shaft assembly 22 is not moving. Therefore, the two drivers 41 will also be in a state of one working and one stopped.

[0029] Specifically, the bushing 43 includes a sleeve body 432431 and a bearing structure. The sleeve body 432431 is fitted onto the rotating shaft assembly 21, and the bearing structure is fitted onto the sleeve body 432431. The second gear 424 is mounted on either the sleeve body 432431 or the bearing structure. Since there are two transmission components 42, their second gears 424 should not interfere with each other. Therefore, the second gears 424 of the two transmission components 42 are respectively mounted on the sleeve body 432431 or the bearing structure to achieve the effect of non-interference of their actions.

[0030] Specifically, one of the transmission components 42 has two second gears 424, which are mounted on the sleeve 432431, and the bearing structure is located between the two second gears 424. The number of second gears 424 in another transmission component 42 is one, and the bearing structure includes two support bearings 433 spaced apart from the sleeve 432431, with the one second gear 424 mounted on the two support bearings 433.

[0031] The above structure achieves transmission stability: one transmission component 42 drives the bushing 43 to rotate, thus enabling synchronous rotation between the two second gears 424; the other transmission component 42 achieves transmission through a second gear plate mounted on the bearing structure. This distribution of the second gears 424 ensures the stability of the bushing 43 and also allows for a more compact spatial arrangement in this invention.

[0032] In this embodiment, the material shaft 221 assembly 22 includes two material shafts 221 and two telescopic devices 222. The two material shafts 221 are respectively used to insert into both ends of the material roll, and the two telescopic devices 222 are respectively used to control the two material shafts 221 to connect to or disconnect from the material roll, thereby achieving the effect of changing the roll of the material roll and achieving the function of changing without stopping the machine.

[0033] Specifically, the telescopic device 222 includes a telescopic cylinder 223, a fixed seat 224, and a telescopic seat 225. The fixed seat 224 is installed on the machine body 1, and the telescopic seat 225 is movably disposed within the fixed seat 224. The material shaft 221 is installed on the telescopic seat 225. The number of telescopic cylinders 223 is at least one.

[0034] The material shaft 221 is installed on the telescopic seat 225, and a bearing can be installed between the material shaft 221 and the telescopic seat 225. When the reel needs to be replaced, the telescopic seat 225 is driven by the telescopic cylinder 223 to move backward, thereby causing the material shaft 221 to disengage from the reel. After the replacement is completed, the telescopic seat 225 drives the material shaft 221 to be reinserted into the reel, thus achieving the replacement effect.

[0035] The fixing seat 224 is preferably a groove 226 that can support the roll, and the material shaft 221 and the roll can be meshed and driven by a gear structure to ensure the efficiency of winding and unwinding.

[0036] In this embodiment, the roller changing module 3 includes a roller changing driver 4131, a drive gear 32, and a driven gear 33. The driven gear 33 is mounted on the mounting base 2. The drive gear 32 meshes with the driven gear 33. The roller changing driver 4131 drives the mounting base 2 to rotate relative to the machine body 1 through the drive gear 32 and the driven gear 33. The mounting base 2 is used to mount at least two rolls.

[0037] In actual use, the roller changer 4131 is mainly composed of a motor and a reducer, while the driven gear 33 covers one side of the mounting base 2. This allows the driven gear 33 to rotate at approximately the same amplitude as the mounting base 2 when the drive gear 32 and the driven gear 33 mesh, thus better controlling the required precision of the rotation of the mounting base 2.

[0038] Specifically, the roller changing module 3 also includes several guide rollers 35, which are rotatably mounted on the machine body 1. The guide rollers 35 have guide parts 36, which are used to abut against the side of the mounting base 2.

[0039] Specifically, the mounting base 2 includes two rotating plates 20, which are rotatably mounted on the machine body 1. The rotating plates 20 have a circular cross-sectional shape and are used to abut against the inner bottom wall of the guide part 36. The rotating shaft assembly 21 and the material shaft 221 assembly 22 are both disposed between the two rotating plates 20.

[0040] The guide roller 35 serves to limit and guide the rotation of the mounting base 2, ensuring that the rotation of the mounting base 2 is smooth enough and does not wobble.

[0041] In this embodiment, the present invention also includes a positioning module 5, which includes a positioning driver 51, a positioning output component 52, a positioning base 53, and a plurality of slide rail assemblies 54 disposed at the bottom of the body 1. The positioning driver 51 drives the positioning output component 52, which is rotatably disposed on the positioning base 53. The positioning driver 51 is used to drive the body 1 to move back and forth along the slide rail assembly 54.

[0042] The position adjustment driver 51 is preferably a cylinder or a motor screw structure, used to control the machine body 1 to move back and forth along the linear path of the slide rail assembly 54, so that the position of this utility model is adjustable relative to other external mechanisms. Therefore, after installation, it can be adaptively adjusted according to the error.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
