Description

Technical Field

[0001] The present invention belongs to the technical field of hand-drawn line drawing equipment, and particularly relates to a three-dimensional to two-dimensional animation hand-drawn line drawing device based on art design. Background Art

[0002] Existing three-dimensional to two-dimensional animation hand-drawn line drawing devices have defects such as low feeding accuracy and uncontrollable material deformation during the paper feeding and discharging processes. This is mainly due to the thin and light characteristics of the paper, which makes it susceptible to air flow disturbance and electrostatic adsorption during mechanical clamping, resulting in local wrinkles caused by uneven pressure distribution of the conveying rollers. At the same time, the adsorption force of traditional vacuum suction cups has a poor matching with the paper grammage, and the inertial effect during high-speed movement causes paper deviation; for plate-like painting materials (such as acrylic plates, wooden boards), existing devices lack an adaptive clamping mechanism and cannot be compatible with plates of different thicknesses and surface roughnesses. Excessive clamping jaw pressure will damage the surface coating of brittle materials, while insufficient pressure will cause rigid plates to slip. The root cause lies in the fact that a mechanical model coupling multiple physical parameters was not constructed during the device design, and a real-time pressure feedback system was not integrated.

[0003] Conventional countermeasures include adding multiple levels of limit baffles to restrict paper displacement, using flexible silicone suction cups to increase friction, and manually pre-adjusting the clamping pressure to adapt to specific plates. However, the limit baffles will hinder the continuous feeding process and reduce the working efficiency by more than 30%; flexible suction cups are prone to aging and cracking during high-frequency operations and require frequent replacement of accessories; manual pressure adjustment depends on operation experience, making it difficult to achieve dynamic load matching and unable to be compatible with plates with a thickness tolerance exceeding ±0.5 mm. Therefore, we hope to design a three-dimensional to two-dimensional animation hand-drawn line drawing device with a novel structure to solve this problem. Summary of the Invention

The upper ends of the two first guide rods 354 are slidably installed inside the lower end of the first housing 352 for guiding movement. A metal plate for magnetic connection is provided at the upper end of the stopper 353; The size and structure of the metal plate match the cross-sectional structure and size of the installation cavity.

[0041] Specifically, by providing the feeding assembly 400, in actual use, first place the paper or sheet-like drawing board into the rear side material box 470 in the inner cavity 423 of the material box 420 (there is an opening and a sealing door at the rear side of the material box 420, and the material box 470 is installed by means of a guide rail drawer and its structure, and the items can be placed by pulling out. This structure adopts the existing technology, and its specific structure and distribution method will not be elaborated here). The stacked paper or sheet-like drawing boards are directly placed on the upper sides of the two upper supporting members 460. When feeding is required, start the lifting rods 461 on the two upper supporting members 460. The two lifting rods 461 are synchronous electric cylinders; Under the action of the jacking rod 461, the two jacking frames 462 can be pushed upward synchronously, thereby driving the stacked paper or sheet-like drawing boards on the upper sides of the two jacking frames 462 to move upward until the uppermost paper or sheet-like drawing board abuts against the lower surface of the suction plate 446. The abutment stop can adopt a pressure sensor or infrared ranging technology. For example, a pressure sensor is installed on the lower side of the suction plate 446. When pressure is detected by the pressure sensor during abutment, the synchronous upward push of the two jacking frames 462 is stopped. As long as the abutment stop is satisfied, it is not limited to a certain special technology. Moreover, the abutting force between the suction plate 446 and the paper or sheet-like drawing board is small, avoiding friction from causing the stacked paper or sheet-like drawing boards to shift or skew. Electrostatic guiding wires can be additionally arranged on the suction plate 446 to conduct the static electricity on the paper or sheet-like drawing board. The specific installation position can be set according to actual use requirements as long as the static electricity conduction requirement is satisfied; Subsequently, the feeding module 440 is started. The servo motor at the rear of the profile rack two 441 drives the toothed belt 442 through the toothed belt pulley, thereby driving the slider 443 on both sides thereof to move forward, and then driving the fixed plate 444 installed between the sliders 443 and the air pipe 445 thereon to move forward. At the same time, the suction plate 446 fixed by the air pipe 445 is also pushed forward. Before starting the feeding module 440, an external negative pressure device sucks the air in the air pipe 445 through a flexible pipe (its operating principle is the same as that of a negative pressure suction cup for fixing materials), which makes the negative pressure holes 447 on the lower side of the suction plate 446 generate negative pressure suction to adsorb and fix the uppermost first paper or sheet-like drawing board in abutment. A communication hole channel is arranged between the front and rear rows of negative pressure holes 447 of the suction plate 446. The middle of the communication hole channel is connected to the lower end of an air pipe 445, and the front end and the rear end of the communication hole channel are respectively connected to a negative pressure hole 447. In this way, negative pressure adsorption can be satisfied. When the first paper or sheet-like drawing board is driven forward by the suction plate 446, since a guide plate inclined at sixty degrees with the front low and the rear high is respectively arranged inside the left front and the right inside of the material box 470, and the front end of the guide plate is close to the rear side of the lower end of the short stick, the height of the lower side of the front end of the guide plate is flush with the height of the lower side of the short stick; With the cooperation of the guide plates on the left and right sides of the material box 470, the front end of the first sheet of paper or sheet-like drawing board is smoothly guided to the position of the short rollers rotating on both sides (in actual use, the difference between the height of the lower surface of the suction plate 446 and the height of the lower surface of the short stick shall not exceed the thickness of the sheet-like drawing board. This type of sheet needs to be relatively thin, and thicker sheet-like drawing boards are not suitable for this device), and gradually moves forward under the action of the upper roller of the traction member 430, and then the front end of the first sheet of paper or sheet-like drawing board is rolled and connected with the guide roller 454 of the pressing member 450, and the elastic curved plate 453 thereon is used to The elastic rod 452 cooperates with the spring 3 to adapt to different thicknesses of paper or sheet drawing boards, so that the guide roller 454 can flatten and guide the paper or sheet drawing boards of different thicknesses to avoid wrinkles or deviations of the paper or sheet drawing boards during feeding. When feeding paper, the suction plate 446 moves to a relatively forward position and then performs adsorption and fixation. If a sheet drawing board is fed, it moves to the middle position for adsorption and fixation. After the suction plate 446 moves to the front extreme position, the negative pressure adsorption is synchronously stopped, and the traction member 430 can be used for transportation at this time. The setting of the feeding component 400 enables the entire device to feed paper or board material drawing boards, which solves the defect that the traditional feeding structure is not compatible with the feeding of flexible materials such as paper and hard material skateboards. The traction member 430, the feeding module 440, the pressure member 450 and the upper support member 460 cooperate with each other, so that the paper or plate material drawing board can be stably transported to the supporting component 300, and the short roller on the traction member 430 cooperates with the guide plate inside the material box 470 and the suction plate 446 of the feeding module 440 and the upper support member 460, so that the paper or plate material drawing board can move forward smoothly and stably, and the guide roller 454 on the pressure member 450 can flatten and guide the moving paper or plate material drawing board. At the same time, the elastic curved plate 453 and the elastic rod 452 thereon enable the guide roller 454 to have the ability to cope with paper or plate material drawing boards of different thicknesses.

[0046] Based on the above first embodiment, further, in actual use, the paper or sheet-like drawing board gradually moves from the feeding assembly 400 through the line outlet 421 in front of the material box 420 to the receiving grooves and the first guide grooves 342 on the corresponding receiving plate 340. Since a limiting member 350 and a guiding member 360 are respectively installed on the left and right sides of the upper ends of the two receiving plates 340, and a limiting member 350 is respectively fixed at the front ends of the left and right sides of the upper surface of the receiving plate 340 on the left part of the support frame 330, and multiple guiding members 360 are equidistantly installed from front to back on the left and right sides of the upper surface of the receiving plate 340 on the left part of the support frame 330; a limiting member 350 is respectively fixed at the rear ends of the left and right sides of the upper surface of the receiving plate 340 on the right part of the support frame 330, and multiple guiding members 360 are equidistantly installed from back to front on the left and right sides of the upper surface of the receiving plate 340 on the right part of the support frame 330. Based on the above, for example, the receiving plate 340 on the right side of the upper end of the support frame 330 receives the conveyed paper or sheet-like drawing board. When the front end of the paper or sheet-like drawing board enters the receiving grooves and the first guide grooves 342 at the rear end of the receiving plate 340, the multiple guiding members 360 on the left and right sides at the rear end of the receiving plate 340 roll and press the edges of the continuously advancing paper or sheet-like drawing board. For paper or board drawing boards with different thicknesses, the internal electromagnet two 363 of the starting guide 360 can be used to adjust the height of the guide wheel 362. If it is for paper feeding, the electromagnet two 363 is not activated. Under the action of the spring two 364, the guide wheel 362 makes rolling contact with the moving paper. If it is for a board drawing board, the electromagnet two 363 is activated to raise the height of the guide wheel 362 so that it can handle a thicker board drawing board and position and guide it. When the front end of the paper or board drawing board reaches below the stopper 350 (which can be detected by an infrared sensor, and the installation position of the infrared sensor can be selected at the rear part of the stopper 350), the current of the electromagnet one 351 is cut off. At this time, the stopper 353 on the lower side of the outer shell one 352 drops under the action of the spring one 355 and gravity. Since the lower side of one end of the stopper 353 close to the feeding assembly 400 is recessed in the opposite direction to form a notch 356 for limiting and pressing the paper, the lower end part of the stopper 353 extends into the slot reserved at the corresponding position of the guide groove one 342, and the part of the notch 356 of the stopper 353 presses and fixes the front corner part of the paper or board drawing board; Subsequently, the telescopic seat 410 can be activated to lower the material box 420. Then, the stepping rotary seat 320 is activated and rotated counterclockwise by 180 degrees to rotate the supporting plate 340 with the feeding completed to the lower side of the painting assembly 200. Subsequently, the horizontal axis 220 and the vertical axis 230 on the profile frame one 210 can be activated (controlled by an external control device such as a PLC to drive the painting pen to move on the X, Y, and Z axes, thereby realizing three-dimensional to two-dimensional anti-freehand line drawing. Here, the painting assembly 200 is based on a two-dimensional plotter, that is, the entire painting assembly 200 is the body of a two-dimensional plotter. With three-dimensional modeling software, a two-dimensional view is generated from the three-dimensional model using the projection function. The two-dimensional lines are artistically processed using engraving software to add irregular jitters or simulate the effect of pencil pressure. The optimized two-dimensional vector is converted into G code using CAM software (such as MasterCAM) to control the two-dimensional plotter to complete the line drawing. The feeding rate of the two-dimensional plotter is adjusted to simulate the change in the freehand speed. The specific model of the two-dimensional plotter can be selected according to actual usage requirements, and its specific structure and operating principle are prior art and will not be elaborated here). For the supporting plate 340 rotated to the other side, the traction member 430 and the stopper 350 provided thereon can be activated. The electromagnet one 351 is activated to pull up the stopper 353 to release the fixation. The traction member 430 pushes the paper or board drawing board that has been painted forward to achieve automatic blanking. Then, the feeding assembly 400 is activated again, and the steps in the first embodiment are repeated for feeding. In this way, by repeating the cycle, the feeding and blanking of the paper or board drawing board for three-dimensional to two-dimensional anti-freehand line drawing can be completed without manual feeding and fixing, which helps to improve work efficiency; The provision of the limiting member 350 can fix the paper or board drawing board for three-dimensional to two-dimensional anti-freehand line drawing, so that when the drawing component 200 is working, the paper or board drawing board for three-dimensional to two-dimensional anti-freehand line drawing will not be displaced to cause defects in drawing. The provision of the guiding member 360 can guide the moving paper or board drawing board for three-dimensional to two-dimensional anti-freehand line drawing to move forward stably without large deviation resulting in the scrapping of the drawing finished product, which helps to improve the quality of the drawing finished product.
