Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drawing collection, and particularly relates to a drawing winding device. BACKGROUND

[0002] In artistic design, as an important creation carrier and achievement display form, the proper winding and preservation of drawings are of great importance. The traditional drawing winding method is often simple and extensive, usually only using ordinary winding drums or directly folding for storage, which has many drawbacks. On the one hand, the drawing is easily damaged by external pressure, friction, and creases during the winding process, greatly affecting the integrity and aesthetics of the drawing. For artistic design drawings, these minor damages can lead to the loss of design details or the difficulty in accurately presenting the design intent. On the other hand, due to the lack of effective protection measures, the drawing is easily damp, stained with dust and other impurities, which not only erodes the paper quality of the drawing and shortens its service life, but also makes the color, line and other design elements on the drawing unclear, seriously affecting the quality and subsequent use value of the drawing.

[0003] In addition, when the drawing needs to be frequently viewed or accessed, the traditional winding method is not convenient for quickly positioning and taking out specific drawings, and it is difficult to ensure the flatness of the drawing during viewing, which brings great inconvenience to the creation process and work display of artistic designers. For example, in the scenarios of internal discussion in the design team, communication of design scheme with customers, or participation in art exhibitions, it is necessary to quickly and clearly display the content of the drawing, but the existing winding method cannot meet these actual needs, resulting in low work efficiency, and even may affect the progress of the design project and the display effect of the work.

[0004] Therefore, in order to solve the above problems, there is an urgent need for a drawing winding device that can safely and efficiently wind and preserve drawings, and is convenient for viewing and taking, to meet the fine requirements of drawing management and use in artistic design, and to ensure that the drawing can maintain a good state throughout its life cycle, providing strong support and guarantee for artistic creation and design work.

[0028] like Figure 3As shown, the separation device 2 9 has the same structure as the separation device 1 7 and is arranged symmetrically. The specific structure of the separation device 1 7 includes a fixed housing 71, a cylinder 1 72, an adsorption housing 1 73, an inner cavity 1 74, an adsorption hole 1 75, a separation channel 76, an adsorption hole 2 77, an inner cavity 2 78, an adsorption housing 2 79, a cylinder 2 710, an annular cavity 711, a movable tube 2 712, a movable tube 1 713, an air pipe 714, and a valve 715.

[0029] The first adsorption shell 73 has a protective layer on its bottom surface, and both sides of the bottom surface of the first adsorption shell 73 are arc-shaped; the second adsorption shell 79 has a protective layer on its top surface, and both sides of the top surface of the second adsorption shell 79 are arc-shaped; both the first adsorption shell 73 and the second adsorption shell 79 are rectangular.

[0030] like Figure 4As shown, the specific structure of the flattening viewing mechanism 8 includes a fixed base 81, guide holes 82, guide pillars 83, cylinder 84, connecting base 85, heating plate 86, lighting lamp 87, heat-conducting plate 88, and transparent base 89. The fixed base 81 is fixedly connected to the center between storage housing 1 2 and storage housing 2 11. Several vertical guide holes 82 are opened on both the left and right sides of the fixed base 81. There are several guide pillars 83, which are movably connected to the corresponding guide holes 82.

The top of the heat-conducting plate 88 is fixedly connected to the heat-conducting plate 88. The transparent base 89 is fixedly connected to the upper side between storage housing 1 2 and storage housing 2 11.

[0031] The bottom surface of the heat-conducting plate 88 is parallel to the top surface of the heat-conducting plate 88.

[0032] like Figure 5 As shown, the structure of the second drive mechanism 14 is the same as that of the first drive mechanism 4. The specific structure of the first drive mechanism 4 includes a motor 41, a transmission shaft 42, a connecting pipe 43, a coil spring 44, and a connecting cavity 45. The motor 41 is fixedly connected to the outside of the storage housing 2. The transmission shaft 42 is movably connected to the inside of the storage housing 2. The connecting pipe 43 is movably connected to the outside of the transmission shaft 42, and a winding drum 3 is fixedly connected to the outside of the connecting pipe 43. The winding drum 3 has a connecting cavity 45 inside. There are several coil springs 44. The inner sides of several coil springs 44 are fixedly connected to the outside of the transmission shaft 42, and the outer sides of several coil springs 44 are fixedly connected to the inner wall of the connecting cavity 45.

[0033] The motor 41 is a servo motor or a stepper motor, which facilitates the control of the motor 41 through existing automation technology; both the protective belt 15 and the protective belt 16 are made of transparent material.

[0034] The invention is used as follows: It features a simple and reasonable structure, low production cost, and convenient installation. During winding and storage, the drawing is first precisely placed between protective belt 15 and protective belt 16. Then, valve 715 is closed, causing adsorption hole 75 to separate from protective belt 15 and adsorption hole 77 to separate from protective belt 16, resulting in protective belts 15 and 16 tightly clamping the drawing. Subsequently, drive mechanism 14 and drive mechanism 24 are activated. Taking drive mechanism 14 as an example, motor 41 (which can be a servo motor or a stepper motor) starts operating, driving the transmission shaft 42 to rotate, which in turn drives the winding via connecting pipe 43. As drum 13 rotates, the coil spring 44 inside drum 13 acts as a buffer and auxiliary mechanism. Drive mechanism 214 operates on the same principle. Protective tape 15 and protective tape 216 reciprocate between drum 13 and drum 213, winding the protective tape containing the drawings onto either drum 213 or drum 13, thus completing the storage of the drawings. If further storage of drawings is required, valve 715 is first opened, and gas is extracted from inner cavity 74 via air pipe 714, creating a negative pressure in inner cavity 74. This pressure causes protective tape 216 to be firmly sucked in through suction hole 277, and protective tape 15 to be sucked in through suction hole 175. Then, cylinders 172 and 2710 are activated to... Its piston rod shortens, driving the adsorption housing 1 73 and adsorption housing 2 79 away from each other, causing the protective belt 1 15 and protective belt 2 16 to separate. At this time, a new drawing can be placed between the protective belts. Then, the above-mentioned winding and storage operation can be repeated. When it is necessary to view or take out the drawing between the protective belts, drive mechanism 1 4 and drive mechanism 2 14 are activated again to move the target drawing between separation device 1 7 and separation device 2 9. At this time, the flattening viewing mechanism 8 located on the upper side between storage housing 1 2 and storage housing 2 11 begins to function. The lighting lamp 87 at the perimeter of the connecting seat 85 lights up, and the light shines through the transparent seat 89 to illuminate the drawing. To view the drawing, if you need to remove it, activate cylinder 3 84. The piston rod extends and pushes the connecting seat 85 upward. The connecting seat 85 then moves the heat-conducting plate 88 upward, flattening the drawing. Finally, repeat the process of placing the drawing again to separate the protective belt 1 15 and the protective belt 2 16, allowing the drawing to be removed smoothly. Throughout the entire process, the protective belt 1 15 and the protective belt 2 16 are made of transparent material, which does not affect the observation of the drawing at all. The drying box 1 5 and the drying box 2 12 keep the internal environment dry, effectively preventing the drawing from getting damp. The guide roller 1 6 and the guide roller 2 10 precisely guide the winding path of the protective belt, effectively ensuring a smooth and unobstructed winding process.

The wiring diagram of the power element and the supply of power are common knowledge in the field.
