Description

Technical Field

[0001] This utility model relates to the field of dipped cord fabric production technology, specifically to a novel gear softening device. Background Art

[0002] After impregnation and heat treatment, the rigidity and stiffness of tire cord fabric increase rapidly. Excessive rigidity and stiffness not only affect the fabric's flexibility and fatigue resistance but also easily cause curling and adhesion during subsequent cutting processes, significantly impacting tire manufacturing. To control the rigidity and stiffness of the tire cord fabric, a softening treatment is necessary. The gear softening device is one of the main devices used in tire cord fabric production to soften the fabric surface. During production, the tire cord fabric, under controlled tension, contacts uniformly meshing gear-shaped rollers at a certain speed. The resulting contact force reduces the rigidity and stiffness of the impregnated tire cord fabric.

[0003] Research has revealed that the gear-shaped rollers in existing gear softening devices are controlled by two separate drive motors and sensors. Due to significant differences in impregnation speed and softening zone tension during the production of different specifications of tire cord fabric, variations in process parameters can easily alter the relative position of the gear-shaped rollers. This can lead to poor engagement of the gear-shaped rollers, causing malfunctions in the gear softening device and damage to the tire cord fabric. In severe cases, it can even cause surface damage to the gear-shaped rollers, shortening their service life. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a novel gear softening device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A novel gear softening device includes a frame, inside which is a gear-shaped roller. The gear-shaped roller includes a driving gear roller and a driven gear roller. The driving gear roller is located on one side of the driven gear roller. One end of the driving gear roller passes through the frame and is connected to a first helical gear through a synchronization component. The first helical gear meshes with a second helical gear. The first and second helical gears are located inside a gear box. The first and second helical gears are respectively connected to a first rotating shaft and a second rotating shaft. The first and second rotating shafts are located inside the gear box. The second helical gear is connected to the driven gear roller through the synchronization component.

[0007] Furthermore, the synchronization component includes a first sprocket located at one end of the drive gear roller, a second sprocket located above the first sprocket, the first sprocket and the second sprocket being connected by a chain, and the second sprocket being connected to the first rotating shaft.

[0008] Furthermore, the synchronization components on the driving gear roller and the driven gear roller have the same structure.

[0009] Furthermore, to facilitate adjustment of the opening and closing range and thus the softening degree of the curtain fabric, the driven gear roller is connected to the swing arm connecting rod at both ends via bearings. One side of the swing arm connecting rod is connected to the floating joint, which is connected to the output end of the cylinder body. One end of one swing arm connecting rod is connected to the second rotating shaft via a bearing, and the other swing arm is connected to the connecting rod via a bearing. The connecting rod is fixedly connected to the frame.

[0010] Furthermore, to ensure the stability of the cylinder body, one end of the cylinder body is connected to the frame via a fixed base.

[0011] Furthermore, in order to drive the drive gear roller, one end of the drive gear roller is connected to the output end of the reducer, and the input end of the reducer is connected to the drive motor.

[0012] Furthermore, the number of teeth and module of the gear-type roller remain consistent.

[0013] Furthermore, the drive motor is fixed to the outside of the frame.

[0014] Furthermore, the second helical gear is installed at the same height as the first helical gear.

[0015] Furthermore, a cover plate is provided at the top of the frame.

[0016] The beneficial effects of the utility model are:

[0017] (1) By setting the first helical gear and the second helical gear and the synchronization component, the device can be driven by a single drive motor, which fundamentally solves the problem of low synchronization and poor coordination of the rollers caused by two drive motors. It also avoids equipment failure caused by changes in the relative position of the gear rollers, thereby extending the service life of the equipment and greatly reducing the equipment maintenance cost.

[0018] (2) The new gear softening device only requires one reducer to drive the roller, which greatly reduces the cost of parts procurement and energy consumption. Attached Figure Description

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] According to an embodiment of the present invention, a novel gear softening device is provided.

[0028] Example 1

[0029] like Figures 1-4 As shown, the novel gear softening device according to an embodiment of the present invention includes a frame 1, inside which is a gear-shaped roller 2. The gear-shaped roller 2 includes a driving gear roller 3 and a driven gear roller 4. The number of teeth and the module of the gear-shaped roller 2 are consistent. The driving gear roller 3 is located on one side of the driven gear roller 4. One end of the driving gear roller 3 passes through the frame 1 and is connected to a first helical gear 5 through a synchronization component. The first helical gear 5 meshes with a second helical gear 6. The second helical gear 6 is installed at the same height as the first helical gear 5. The first helical gear 5 and the second helical gear 6 are located inside a gear box 7. The first helical gear 5 and the second helical gear 6 are respectively connected to a first rotating shaft 8 and a second rotating shaft 9. The first rotating shaft 8 and the second rotating shaft 9 are located inside the gear box 7. By setting the gear box 7, not only can the intrusion of external dust and impurities be blocked, but a relatively clean and stable internal environment can also be provided for the first helical gear 5 and the second helical gear 6.

[0030] The second helical gear 6 is connected to the driven gear roller 4 through a synchronization assembly. The synchronization assembly includes a first sprocket 10 located at one end of the driving gear roller 3, and a second sprocket 11 located above the first sprocket 10. The first sprocket 10 and the second sprocket 11 are connected by a chain 12. The second sprocket 11 is connected to the first rotating shaft 8. The synchronization assemblies on the driving gear roller 3 and the driven gear roller 4 have the same structure. One end of the driving gear roller 3 is connected to the output end of the reducer 18. The reducer 18 is a parallel shaft helical gear reducer 18. The input end of the reducer 18 is connected to the drive motor 19. The drive motor 19 is fixed to the outside of the frame 1.

[0031] Through the above scheme, the drive motor 19 is started and decelerated by the reducer 18, which drives the drive gear roller 3 to rotate. The rotation of the drive gear roller 3 drives the first sprocket 10 at one end of the drive gear roller 3 to rotate. The rotation of the first sprocket 10 drives the chain 12 and the second sprocket 11 to rotate, thereby driving the first helical gear 5 to rotate. The rotation of the first helical gear 5 drives the second helical gear 6 to rotate, thereby driving the driven gear roller 4 to rotate. The drive gear roller 3 and the driven gear roller 4 rotate synchronously in opposite directions, which facilitates the softening operation of the curtain fabric and allows for adaptive adjustment according to the conveying speed and tension of the curtain fabric.

[0032] like Figures 1-4 As shown, the driven gear roller 4 is connected to the swing arm connecting rod 13 at both ends via bearings. One side of the swing arm connecting rod 13 is connected to the floating joint 14, which is connected to the output end of the cylinder body 15. One end of one swing arm connecting rod 13 is connected to the second rotating shaft 9 via a bearing, and the other swing arm connecting rod 13 is connected to the connecting rod 16 via a bearing. The connecting rod 16 is fixedly connected to the frame 1. One end of the cylinder body 15 is connected to the frame 1 via a fixed seat 17. The top of the frame 1 is provided with a cover plate 20. With the above scheme, the swing arm connecting rod 13 can be moved by starting the cylinder body 15 as needed, in conjunction with the floating joint 14, thereby moving the driven gear roller 4. This allows for the adjustment of the meshing state and amplitude of the driving gear roller 3 and the driven gear roller 4.

[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting the first helical gear 5 and the second helical gear 6 as well as the synchronization component, the device can be driven by a single drive motor 19. This fundamentally solves the problem of low synchronization and poor coordination of the rollers caused by two drive motors 19, and also avoids equipment failure caused by changes in the relative position of the gear-type roller 2. This extends the service life of the equipment, greatly reduces the equipment maintenance cost, and the gear softening device only requires the installation of one reducer 18 to drive the gear-type roller 2, which greatly reduces the cost of parts procurement and energy consumption.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
