Description

Technical Field

[0001] This utility model relates to the field of polarizing film processing technology, specifically a polarizing film stretching device. Background Technology

[0002] The full name of a polarizer is polarizing film. The imaging of liquid crystal displays must rely on polarized light. All liquid crystals have two polarizing films, one in front and one behind, which are closely attached to the liquid crystal glass to form a liquid crystal film with a total thickness of about 1mm.

[0003] Polarizing films need to be stretched during processing, but existing stretching devices are prone to misalignment of the polarizing film during actual use. Once the polarizing film misaligns, it directly affects the stretching effect of the polarizing film. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stretching device for a polarizing film, comprising a housing, a conveying mechanism installed on the bottom inner wall of the housing, and the conveying mechanism including a conveying seat fixedly connected to the bottom inner wall of the housing, two symmetrically arranged limiting components slidably installed on the top outer wall of the conveying seat, two fixed seats fixedly connected to both sides of the outer wall of the conveying seat, and two conveying rollers rotatably connected between the four fixed seats, and four symmetrically arranged electric slide rails installed on the top outer wall of the conveying seat.

[0006] By adopting the above structure, the housing facilitates the installation of the conveying mechanism. The arrangement of the conveying seat and the cooperation between the conveying rollers in the conveying mechanism facilitates the conveying and stretching of the polarizing film. The electric slide rail facilitates the movement of the two limiting components.

[0007] Optionally, the limiting component includes an adjustment box slidably connected to two electric slide rails, and an installation box is installed on one outer wall of the adjustment box. Multiple equidistant correction shafts are rotatably connected to the inner walls of both sides of the installation box.

[0008] By adopting the above structure, the electric slide rail facilitates the sliding of the adjustment box, the mounting box facilitates the installation of the correction shaft, and the correction shaft facilitates direct contact with the polarizing film, thereby reducing the wear of the polarizing film during transport.

[0009] Optionally, the regulating box has an internal mounting cavity, and the same bidirectional screw is rotatably connected to the inner walls of both sides of the mounting cavity.

[0010] By adopting the above structure, the bidirectional screw can be easily rotated and installed by adjusting the mounting cavity in the box.

[0011] Optionally, the outer wall of the bidirectional screw is screwed with two symmetrically arranged threaded sleeves, and the outer walls of both threaded sleeves are rotatably connected to a connecting plate.

[0012] By adopting the above structure, the two threaded sleeves can be directly driven to move towards or away from each other by the rotation of the bidirectional screw.

[0013] Optionally, a worm gear is fixedly connected to the midpoint of the bidirectional screw, a servo motor is fixedly connected to the inner wall of the mounting cavity, and a worm is fixedly connected to the output shaft of the servo motor, with the worm and the worm gear meshing with each other.

[0014] By adopting the above structure, the worm gear is directly driven to rotate by the servo motor, and the rotation of the worm gear directly drives the bidirectional screw to rotate.

[0015] Optionally, the top inner wall of the mounting cavity is fixedly connected to two symmetrically arranged support seats, and the bidirectional screw is rotatably mounted on the two support seats.

[0016] By adopting the above structure, the installation cavity facilitates the installation of the auxiliary support seat and also facilitates the auxiliary support of the bidirectional screw.

[0017] Optionally, each of the two support bases has a mounting rod fixedly connected to one outer wall, and the two mounting rods have the same sliding frame slidably connected to their outer walls. One end of the sliding frame is fixedly connected to the mounting box, and one end of each of the two connecting plates is rotatably connected to the sliding frame.

[0018] By adopting the above structure, the sliding frame can be easily slidably installed by setting the mounting rod. When the sliding seat moves, the position of the mounting box can be easily adjusted directly. When the two threaded sleeves move towards each other, the sliding frame can be moved directly through the connecting plate.

[0019] Optionally, a control panel is fixedly connected to one side of the outer wall of the housing, and discharge ports are provided on both sides of the outer wall of the housing.

[0020] By adopting the above structure, the electrical components in the tensioning device can be easily controlled through the control panel settings.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model sets two limiting components on the conveying mechanism. The setting of the limiting components makes it convenient to limit the conveyed polarizing film, thereby effectively avoiding the polarizing film from shifting during the stretching and conveying process, and solving the problem that the existing polarizing film is prone to shifting during the stretching and conveying process.

[0023] (2) By setting a bidirectional screw in the adjustment box, the cooperation between the bidirectional screw, the threaded sleeve and the connecting plate makes it convenient to adjust the position of the mounting box by the sliding frame, thus solving the problem that the existing mounting box is inconvenient to fine-tune.

[0033] For details, please refer to Figure 3-5 The limiting component 7 includes an adjustment box 11 slidably connected to two electric slide rails 6, and an installation box 10 is installed on one outer wall of the adjustment box 11. Multiple equidistant correction shafts 12 are rotatably connected to the inner walls of both sides of the installation box 10. The electric slide rails 6 facilitate the sliding of the adjustment box 11, and the installation box 10 facilitates the installation of the correction shafts 12. The correction shafts 12 are designed to directly contact the polarizing film, thereby reducing the wear of the polarizing film during transport. The adjustment box 11 has an installation cavity 13 inside, and the same bidirectional screw 14 is rotatably connected to the inner walls of both sides of the installation cavity 13. The installation cavity 13 in the adjustment box 11 facilitates the rotational installation of the bidirectional screw 14.

[0034] For details, please refer to Figure 4-5 Two symmetrically arranged threaded sleeves 15 are screwed onto the outer wall of the bidirectional screw 14, and a connecting plate 21 is rotatably connected to the outer wall of each threaded sleeve 15. The rotation of the bidirectional screw 14 directly drives the two threaded sleeves 15 to move towards or away from each other. A worm gear 18 is fixedly connected at the midpoint of the bidirectional screw 14. A servo motor 17 is fixedly connected to the inner wall of the mounting cavity 13, and a worm 16 is fixedly connected to the output shaft of the servo motor 17.

When the worm gear 18 rotates, it directly drives the bidirectional screw 14 to rotate.

[0035] For details, please refer to Figure 5 The top inner wall of the mounting cavity 13 is fixedly connected to two symmetrically arranged support seats 19.

At the same time, the distance between the two limiting components 7 is adjusted according to the specifications of the polarizing film. During adjustment, the position of the limiting components 7 is adjusted directly by the electric slide rail 6. After the adjustment, if there is still a certain gap between the correction shaft 12 and the polarizing film, the servo motor 17 is started directly. When the servo motor 17 is started, it directly drives the worm wheel 18 to rotate through the worm 16. When the worm wheel 18 rotates, it directly drives the bidirectional screw 14 to rotate. When the bidirectional screw 14 rotates, it drives the two threaded sleeves 15 to move towards or away from each other. When the two threaded sleeves 15 move, they directly drive the sliding frame 20 to move through the connecting plate 21, thereby facilitating the adjustment of the position of the mounting box 10.
