Description

Technical Field

[0001] The utility model relates to the technical field of polarizing plate production, in particular to a cloth storage mechanism for polarizing plate production. Background Art

[0002] Polarizing plates are widely used as polarization supply elements or polarization detection elements in liquid crystal display devices. Traditionally, these plates consisted of a polarizing film composed of polyvinyl alcohol bonded to a protective film composed of triacetyl cellulose. However, with the recent incorporation of liquid crystal display devices into mobile devices such as laptop computers and mobile phones, and even large televisions, polarizing plates have been required to be thinner and lighter. Furthermore, as these devices become more portable, their use in a wider range of locations has led to a demand for improved durability.

[0003] In the prior art, the cloth storage mechanism for polarizing plate production is mainly used in the polarizing plate production process, especially in the polarizing film coating production process. This mechanism is mainly to ensure that when the roll is changed and the film is spliced, the film splicing will be temporarily stopped, while the production is continuous. The film storage is to ensure that the continuity of production is not affected. However, the existing cloth storage device cannot detect the tension change and cannot reach the normal speed of the machine startup. It often causes the large roll to deviate from the winding speed, which easily affects the product quality and makes it impossible to guarantee the quality consistency of the product during production. In addition, the production cost is relatively high and the space occupied by the production equipment is relatively large.

[0004] Therefore, we disclose a cloth storage mechanism for polarizing plate production to meet the need for detecting tension changes in the cloth storage device, adapt to different production needs, and reduce the need for manual intervention. Utility Model Content

Example

[0030] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a cloth storage mechanism for polarizing plate production comprises a support frame 1, a carrying plate 2 is fixedly connected to the top of the support frame 1, a trigger component is provided in the support frame 1 for judging the tension change of the cloth; an expansion component is provided in the support frame 1 for adjusting the tension of the cloth; rotating rollers 3 are rotatably connected to the inner wall of the support frame 1, a plurality of groups of rotating rollers 3 are rotatably connected to the inner wall of the support frame 1, a driving motor 7 is provided at one end of the rotating rollers 3, a feed plate 4 is provided on one side of the carrying plate 2, a discharge table 5 is obliquely provided on the other side of the carrying plate 2, and an adjustment source 6 is provided on one side of the support frame 1, and the adjustment source 6 is used to adjust the production speed of the polarizing plate.

[0031] Specifically, the support frame 1 is fixedly connected to the carrier plate 2 for carrying the cloth, and the rotating roller 3 is driven to rotate by the driving motor 7, so that after the cloth enters the feed plate 4, it is transmitted to the discharge platform 5 through the carrier plate 2, and finally the cloth conveying process is completed, making the cloth transmission more stable and efficient. The trigger component and the expansion component are respectively arranged on the inner wall of the support frame 1, which enhances the stability of the cloth during the transmission process, avoids the knotting and wrinkling of the cloth, and improves the production efficiency. The adjustment source 6 can adjust the production speed of the polarizing plate to adapt to different production needs, effectively improving the automation level of polarizing plate production, reducing the necessity of manual intervention, and having significant economic benefits and practical value.

[0032] Preferably, the trigger assembly includes a rotating ring 8 rotatably connected to the rotating roller 3, a connecting arm 9 is fixedly connected to the rotating ring 8, and a plurality of telescopic rods 10 are fixedly connected to the bottom of the connecting arm 9. The telescopic rod 10 is a telescopic structure, and the bottom of the telescopic rod 10 is fixedly connected to a support plate 12. A reset elastic member 11 is fixedly sleeved on the telescopic rod 10, one end of the reset elastic member 11 is fixedly connected to the bottom of the connecting arm 9, and the other end of the reset elastic member 11 is fixedly connected to the top of the support plate 12. A contact roller 13 is rotatably connected to the inner wall of the support plate 12, and the surface of the contact roller 13 is made of rubber. The contact roller 13 is provided with a plurality of expansion slots 14, and the expansion slots 14 are in contact with the film used for the production of polarizing plates.

[0033] Specifically, when the rotating roller 3 rotates, it drives the rotating ring 8 to rotate synchronously, and the connecting arm 9 also moves accordingly. The multiple groups of telescopic rods 10 at the bottom of the connecting arm 9 can be extended and retracted to adapt to different tensions and position changes of the fabric. The support plate 12 fixedly connected to the bottom of the telescopic rod 10 always maintains a certain elastic pressure through the action of the reset elastic member 11. The contact roller 13 rotatably connected on the inner wall of the support plate 12 contacts the surface of the fabric and ensures smooth transmission of the fabric through multiple groups of expansion grooves 14. The expansion grooves 14 contact the film used in the production of polarizing plates, ensuring a close bond between the fabric and the film. Through the combination of the telescopic rod 10 and the reset elastic member 11, the position of the support plate 12 can be flexibly adjusted to ensure stable contact between the fabric and the contact roller 13, avoiding slipping or wrinkling of the fabric during transmission. The expansion grooves 14 increase the contact area between the fabric and the film, thereby improving the bonding effect between the fabric and the film during the production process. This structure not only improves the stability and production efficiency of fabric transmission, but also effectively guarantees the quality and consistency of the polarizing plates, and has significant practical application value.

[0034] Preferably, the expansion assembly includes a rotating rod 17 fixedly connected to the inner wall of the support frame 1, one end of the rotating rod 17 is fixedly and rotatably connected to a synchronous gear 18, and a plurality of guide grooves 22 are provided on the synchronous gear 18, and the guide groove 22 is an arc-shaped structure deflected to one side, and a limiting rod 23 is slidably connected in the guide groove 22, and one end of the limiting rod 23 is fixedly connected to a moving rod 21, and the moving rod 21 is slidably connected in the sliding groove 20, and one end of the moving rod 21 is fixedly connected to an expansion plate 24, and multiple groups of expansion plates 24 can be spliced ​​to form a complete circle, one end of the connecting arm 9 is fixedly connected to an extension arm 15, and a plurality of drive teeth 16 are provided on the top of the extension arm 15; a drive gear 19 is rotatably connected to the inner wall of the support frame 1, and the drive gear 19 is meshed with the drive tooth 16.

[0035] Specifically, when the driving tooth 16 drives the driving gear 19 to rotate, the synchronous gear 18 meshing with it rotates synchronously, and the guide groove 22 on the synchronous gear 18 guides the limiting rod 23 to slide. The movement of the limiting rod 23 drives the moving rod 21 to slide in the sliding groove 20. One end of the moving rod 21 is fixedly connected to an expansion plate 24. A complete circular structure can be formed by splicing multiple groups of expansion plates 24. The expansion assembly can evenly expand the fabric, which not only improves the stability and uniformity of the fabric during transmission, but also effectively avoids the offset and deformation problems of the fabric during the expansion process, ensuring the high quality and consistency of the fabric in the production process of polarizing plates, and has significant practical application value.

[0036] As can be seen from the above, when the cloth storage mechanism for polarizing plate production is working, the rotating roller 3 is driven to rotate by the driving motor 7, so that after the cloth enters the feed plate 4, when the rotating roller 3 rotates, the rotating ring 8 is driven to rotate synchronously, and the connecting arm 9 also moves accordingly. The multiple groups of telescopic rods 10 at the bottom of the connecting arm 9 can be telescopic to adapt to the different tensions and position changes of the cloth. The support plate 12 fixedly connected to the bottom of the telescopic rod 10 always maintains a certain elastic pressure through the action of the reset elastic member 11. The contact roller 13 rotatably connected on the inner wall of the support plate 12 contacts the surface of the cloth and ensures the smooth transmission of the cloth through multiple groups of expansion slots 14. The expansion slot 14 contacts the film used for polarizing plate production to ensure the cloth and the film. The close combination between them, when the driving tooth 16 drives the driving gear 19 to rotate, the synchronous gear 18 meshing with it rotates synchronously, and the guide groove 22 on the synchronous gear 18 guides the limiting rod 23 to slide. The movement of the limiting rod 23 drives the moving rod 21 to slide in the sliding groove 20. One end of the moving rod 21 is fixedly connected with an expansion plate 24. A complete circular structure can be formed by splicing multiple groups of expansion plates 24. The expansion component can evenly expand the fabric, which not only improves the stability and uniformity of the fabric during transmission, but also effectively avoids the offset and deformation problems of the fabric during the expansion process, ensuring the high quality and consistency of the fabric in the production process of polarizing plates, and has significant practical application value.
