Description

Technical Field

[0001] This utility model relates to the field of optical film processing technology, specifically to a raw material mixing device for optical film production. Background Technology

[0002] Optical films are thin films that utilize light interference to prevent light from passing through. They are deposited or coated onto optical elements to alter the optical properties of the substrate. Optical films are typically classified according to their characteristics into brightness enhancement films, diffusion films, reflection films, composite films, filters, polarizers, etc. By coating and treating the surface of optical materials, their optical properties can be altered, enabling control over the transmission, reflection, and refraction of light.

[0003] According to the Chinese patent publication number CN219634222U, "A Raw Material Mixing Device for Breathable Membrane Production", the main process involves feeding various raw materials into different chambers, activating the drive mechanism, which drives the drive shaft and stirring mechanism to rotate, and allowing the raw materials in the hopper to enter the discharge pipe from the discharge port. The spiral blades installed on the drive shaft transport the raw materials to the bottom of the hopper, gradually lowering and mixing them, resulting in good mixing effect and uniform mixing.

[0004] Optical films are typically mixed using a reaction vessel during processing. Some reaction vessels have heating structures installed in the inner wall jacket. During the mixing process, some of the optical film raw materials adhere to the inner wall of the reaction vessel and gradually harden under the heating of the heating structure, affecting the mixing accuracy and effect of the raw materials.

[0005] Therefore, a raw material mixing device for optical film production is proposed to solve the problem of some raw materials sticking together during the reaction process, resulting in poor mixing accuracy and effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is that some raw materials stick together during the reaction process, resulting in poor mixing accuracy and effect. Therefore, a raw material mixing device for optical film production is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a raw material mixing device for optical film production, including a kettle body, a discharge port, a spiral heat pipe and a cover. A first motor is fixedly connected to the upper end of the cover. A drive rod is fixedly connected to the output end of the first motor. A connecting plate is fixedly connected to the upper side of the drive rod. Electric push rods are fixedly connected to the four sides of the bottom end of the connecting plate. A moving plate is fixedly connected to the output end of the electric push rod. A connecting sleeve is fixedly connected to the center of the moving plate. The connecting sleeve is fitted with the drive rod. A connecting ring is provided on the bottom side of the moving plate. The connecting ring is fixedly connected to the kettle body. A second motor is fixedly connected to the upper end of the moving plate. A rotating rod is fixedly connected to the output end of the second motor. A stirring column is evenly fixedly connected to one side of the rotating rod. A first scraper is evenly fixedly connected to the side of the rotating rod away from the stirring column, and the positions of the first scrapers on the two rotating rods are staggered. A second scraper is rotatably connected to the bottom end of the rotating rod. The second scraper is fixedly connected to the drive rod.

[0008] As a preferred technical solution of this utility model, the first scraper has a triangular structure, and turbulence grooves are evenly provided on the upper and lower sides of the first scraper. By setting the turbulence grooves, the turbulence is increased and the stirring effect is improved.

[0009] As a preferred technical solution of this utility model, a limiting hole is provided in the first scraper, and an extension rod is movably inserted into the first scraper within the limiting hole. A spring is in contact with one side of the extension rod. By setting the extension rod and the spring, the effective stirring radius of the first scraper can be increased, and the stirring effect can be improved.

[0010] As a preferred technical solution of this utility model, a retaining strip is fixedly connected to the bottom side of the first scraper located at the lowest side. The retaining strip corresponds to the inner wall of the vessel. By setting the retaining strip to contact the bottom side of the vessel, the contact between the second scraper and the inner wall of the vessel can be reduced, thereby reducing wear during rotation.

[0011] As a preferred technical solution of this utility model, a support column is fixedly connected to the connecting plate, and a sliding ball is rotatably embedded on both the support column and the connecting ring. By setting the support column and the sliding ball, the stability of the connecting plate when rotating can be improved.

[0012] This utility model has the following advantages: by setting a drive rod on the cover to drive the connecting plate and the moving plate to rotate, the electric push rod drives the moving plate to move up and down, and at the same time the second motor can cause the rotating rod to rotate, so that the first scraper and the second scraper contact the inner wall of the kettle, thereby improving the mixing effect of raw materials and reducing the material adhesion to the inner wall of the kettle, thus improving the mixing accuracy of materials.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The illustrated raw material mixing device for optical film production includes a vessel body 1, a discharge port 2, a spiral heat pipe 3, and a cover 4. The spiral heat pipe 3 is externally connected to a wire, which heats the vessel body 1 and the materials inside. A first motor is fixedly connected to the upper end of the cover 4. This first motor is a drive motor, and its operating program is self-contained. The first motor drives the drive rod 5 to rotate, causing the two rotating rods 11 to rotate around the central axis of the vessel body 1. At this time, the first scraper 13 and the stirring column 12 perform the effect of stirring and mixing the materials. The output end of the first motor is fixedly connected to the drive rod 5. A connecting plate 6 is fixedly connected to the upper side of the drive rod 5. Electric push rods 7 are fixedly connected to the four sides of the bottom end of the connecting plate 6. When the electric push rods 7 extend, they can cause the moving plate 8 to move, thereby causing the second scraper 14 to contact the inner wall of the bottom side of the vessel body 1. A movable plate 8 is fixedly connected to the output end of the push rod 7. A connecting sleeve 9 is fixedly connected to the center of the movable plate 8. The connecting sleeve 9 is fitted with the drive rod 5. A connecting ring 10 is provided on the bottom side of the movable plate 8. The connecting ring 10 is fixedly connected inside the vessel body 1. A second motor is fixedly connected to the upper end of the movable plate 8. The second motor is a YA series motor. It performs timed forward and reverse rotation inside the vessel body 1. A rotating rod 11 is fixedly connected to the output end of the second motor. A stirring column 12 is evenly fixedly connected to one side of the rotating rod 11. The second motor drives the rotating rod 11 to rotate, so that the first scraper 13 or the stirring column 12 can correspond to the inner wall of the vessel body 1 respectively. The first scraper 13 is evenly fixedly connected to the side of the rotating rod 11 away from the stirring column 12. The positions of the first scrapers 13 on the two rotating rods 11 are staggered. A second scraper 14 is rotatably connected to the bottom end of the rotating rod 11. The second scraper 14 is fixedly connected to the drive rod 5.

[0019] The first scraper 13 has a triangular structure, and turbulence grooves 17 are evenly provided on the upper and lower sides of the first scraper 13. By setting the turbulence grooves 17, the turbulence can be increased, which facilitates the mixing of materials.

[0020] The first scraper 13 has a limiting hole, and an extension rod 15 is movably inserted into the first scraper 13 within the limiting hole. One side of the extension rod 15 is in contact with a spring. By setting the extension rod 15, the stirring distance of the stirring column 12 is further increased, thereby improving the uniformity of stirring.

[0021] Among them, the bottom side of the first scraper 13 located at the lowest side is fixedly connected with a retaining strip 16. The retaining strip 16 corresponds to the inner wall of the vessel body 1. By setting the retaining strip 16, when the electric push rod 7 extends and when the first scraper 13 contacts the inner wall of the vessel body 1, the retaining strip 16 contacts the bottom side of the inner wall of the vessel body 1, sealing the gap between the second scraper 14 and the inner wall of the vessel body 1, thereby improving the cleaning effect.

[0022] Among them, a support column 18 is fixedly connected to the connecting plate 6. Both the support column 18 and the connecting ring 10 are rotatably embedded with a sliding ball. By setting the support column 18, the stability of the connecting plate 6 when rotating can be improved, and the sliding ball can reduce friction.

[0023] Working principle: The material is put into the vessel 1, the cover 4 is closed, and then the first motor is started. The first motor drives the drive rod 5 to rotate. At this time, the connecting plate 6 and the moving plate 8 rotate, and then the rotating rod 11 rotates. The first scraper 13, the second scraper 14 and the stirring column 12 perform the stirring action. In conjunction with the spiral heat pipe 3, the material is mixed and heated. After a period of time, the electric push rod 7 extends and causes the moving plate 8 to move down. At this time, the second scraper 14 contacts the inner bottom side wall of the vessel 1. At the same time, the second motor drives the rotating rod 11 to rotate, so that the first scraper 13 contacts the inner wall of the vessel 1. At this time, under the action of the first motor and the drive rod 5, the first scraper 13, the second scraper 14 and the clamping strip 16 can clean the inner wall of the vessel 1, avoid the material sticking caused by heating, and improve the mixing accuracy of the material.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
