Description

Technical Field

[0001] This utility model relates to the field of projection device technology, specifically a holographic projection device for paper tray production patterns. Background Technology

[0002] In the paper tray production field, traditional pattern prototyping technology has long relied on physical molds or flat printing, which has significant drawbacks such as low efficiency, high cost and insufficient precision. Physical mold making requires complex processes such as carving and debugging, and the single prototyping cycle can last for several days and the modification cost is high. Flat printing is difficult to present the three-dimensional effect of the pattern on the curved paper tray, resulting in a deviation rate of more than (15)% between the finished product and the design. At the same time, the waste generated by physical prototyping is in conflict with the green concept advocated by the paper tray industry. With the breakthrough development of holographic projection technology, its three-dimensional dynamic imaging capability realized by the principle of interference diffraction provides a revolutionary solution for paper tray prototyping.

[0003] Paper tray products often have complex curved surfaces such as arcs and waves. Adjusting the projection height can dynamically adjust the angle between the light and the surface, compensating for the optical distortion caused by the curved surface. When using existing holographic projection devices, they are generally assembled at a fixed projection point, and the projection height is inconvenient to adjust. This makes it impossible for the projector to adapt to paper tray surfaces with different curvatures, which may lead to blurred or distorted edges of the pattern. For example, when projecting onto an arc-shaped paper tray, a fixed height may cause an improper angle of light, causing the pattern to be stretched or compressed locally. Therefore, corresponding improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a holographic projection device for paper tray production patterns, so as to solve the problem that the existing holographic projection devices for paper tray production patterns mentioned in the background art have a fixed projection height, which is inconvenient to adjust and results in a decrease in projection imaging accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a holographic projection device for paper tray production patterns, comprising a base, a protective box, and a box door, wherein the protective box is connected to the top of the base, and the box door is movably hinged to one side of the protective box;

[0006] The protective box has heat dissipation grooves evenly arranged on one side. The holographic projector body is connected inside the protective box. The top of the protective box is connected to the image cover, which is made of high light transmittance polycarbonate. The bottom of the protective box is provided with a dynamic adjustment mechanism, and fixing components are evenly arranged around the dynamic adjustment mechanism.

[0007] Preferably, both sides of the base are fixed with support seats, and the support seats are used to support the dynamic adjustment mechanism.

[0008] Preferably, the dynamic adjustment mechanism includes a drive motor, which is mounted on the outside of the base. The output shaft of the drive motor is connected to a drive shaft. One end of the drive shaft is fixed with a drive gear, and a driven gear meshes with one side of the drive gear. A driven shaft is fixed inside the driven gear, and one end of the driven shaft is rotatably connected to the support base.

[0009] Preferably, a first flipping frame is fixedly sleeved on the outside of the drive shaft, and a first flipping frame is rotatably connected to the outside of the driven shaft. A second top bracket is connected to both sides of the top of the first flipping frame, and a first top bracket is connected to both sides of the top of the second flipping frame.

[0010] Preferably, the fixing component includes a movable seat movably connected to one end of the top bracket one and the top bracket two, and a support column is connected to one end of each movable seat, and a fixed foot is connected to the bottom end of each support column.

[0011] Preferably, the fixed feet are provided with fixing holes on both sides inside, and the base is assembled to the place of use by using bolts to cooperate with the fixing holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This paper tray production pattern holographic projection device is safe and efficient to use, and the projection height is adjustable to adapt to paper tray surfaces with different curvatures, ensuring projection accuracy. When the holographic projector is in use, it is protected by a protective box to resist mechanical damage in the production environment and avoid damage caused by external collisions and vibrations, which helps to extend the service life of the holographic projector.

[0014] The drive motor rotates the drive shaft and drive gear, with the drive gear meshing with the driven gear to make the driven shaft rotate synchronously. This causes the first and second flipping frames to rotate in opposite directions, thereby causing the first and second top supports to flip upwards around the movable seat. This lifts the entire protective box upwards, adjusting its height to avoid blurring or distortion of the pattern edges due to improper projection distance. Especially when presenting a three-dimensional relief effect, height adjustment ensures clear light and shadow layers. For paper trays with different curvatures, height adjustment can compensate for the optical distortion caused by the curved surface, making the projected pattern perfectly fit the actual shape of the paper tray in three-dimensional space, reducing the error rate, and thus improving the projection quality of the paper tray.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1-5 The present invention provides an embodiment of a holographic projection device for paper tray production patterns, comprising a base 1, a protective box 2, and a door 3. The protective box 2 is connected to the top of the base 1, and the door 3 is movably hinged to one side of the protective box 2. The protective box 2 is used to protect the holographic projector body 9 to prevent external impacts from causing physical damage to the holographic projector body 9. Support seats 10 are fixed on both sides inside the base 1, and the support seats 10 are used to support the dynamic adjustment mechanism 5.

[0023] The protective box 2 has heat dissipation slots 201 evenly arranged on one side. The holographic projector body 9 is connected inside the protective box 2. The top of the protective box 2 is connected to the image cover 4, and the image cover 4 is made of high light transmittance polycarbonate. The bottom of the protective box 2 is equipped with a dynamic adjustment mechanism 5.

[0024] The dynamic adjustment mechanism 5 includes a drive motor 501, which is mounted on the outside of the base 1. The output shaft of the drive motor 501 is connected to a drive shaft 502. One end of the drive shaft 502 is fixed with a drive gear 504, and a driven gear 505 meshes with one side of the drive gear 504. A driven shaft 503 is fixed inside the driven gear 505, and one end of the driven shaft 503 is rotatably connected to the support base 10.

[0025] A tilting frame 506 is fixedly sleeved on the outside of the drive shaft 502, and a tilting frame 506 is rotatably connected to the outside of the driven shaft 503. Top brackets 509 are connected to both sides of the top of the tilting frame 506, and top brackets 508 are connected to both sides of the top of the tilting frame 507.

[0026] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In use, the drive motor 501 drives the drive shaft 502 and drive gear 504 to rotate. The drive gear 504 meshes with the driven gear 505, which causes the driven shaft 503 to rotate synchronously. This causes the first flipping frame 506 and the second flipping frame 507 to rotate in opposite directions, thereby causing the first top support 508 and the second top support 509 to flip upward around the movable seat 6, so as to lift the entire protective box 2 upward. Adjusting the height of the protective box 2 and the holographic projector body 9 avoids blurring or distortion of the pattern edges due to improper projection distance. Especially when presenting a three-dimensional relief effect, height adjustment can ensure clear light and shadow layers. During the projection process, the high-transmittance polycarbonate image mask 4 of the holographic projector body 9 enhances the floating effect of the image, resulting in a better projection effect.

[0027] Furthermore, the dynamic adjustment mechanism 5 is uniformly surrounded by fixing components; the fixing components include movable seats 6 that are movably connected to one end of the top bracket 1 508 and the top bracket 2 509, and each movable seat 6 is connected to a support column 7 at one end, and each support column 7 is connected to a fixed foot 8 at the bottom end.

[0028] For specific details, refer to the base platform 1 and the protective box 2. In use, the movable seat 6 is movably connected to the support column 7, so that the top bracket 1 508 and the top bracket 2 509 can be rotated normally, and the protective box 2 can be lifted normally.

[0029] The fixed feet 8 have fixing holes 801 on both sides inside. The base 1 is assembled to the place of use by using bolts to cooperate with the fixing holes 801.

[0030] For details, please refer to Figure 1 , Figure 2 , Figure 4 When in use, simply pass the bolt through the fixing hole 801 to fix and limit the fixing foot 8, and then install the base 1 and the protective box 2 into the use position as a whole. The operation is convenient.

[0031] Working principle: First, bolts are inserted through fixing holes 801, and then fixing feet 8 are fixed to the projection placement point. Then, the holographic projector body 9 is used to assist in projecting holographic images. The high light transmittance polycarbonate material display cover 4 is used to prevent dust, hair and other particles from adhering to the lens or projection film, and to prevent image blurring caused by light scattering.

[0032] Secondly, during the holographic projection of the pattern in the paper tray production process, the drive motor 501 drives the drive shaft 502 and the drive gear 504 to rotate. The drive gear 504 meshes with the driven gear 505, which causes the driven shaft 503 to rotate synchronously. This causes the first flipping frame 506 and the second flipping frame 507 to rotate in opposite directions, thereby causing the first top support frame 508 and the second top support frame 509 to flip upward around the movable seat 6. This lifts the entire protective box 2 upward, adjusts the height of the protective box 2, and avoids blurring or distortion of the pattern edges due to improper projection distance, thus ensuring higher projection quality.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
