[0020] 1. For this auxiliary device for computer drawing, first, a servo motor provides a unified driving source. After the meshing stroke between two groups of driven circular gears and a driving circular gear is adjusted in place by two first electric push rods, two groups of driving bevel gears drive the forward and reverse lead screws on two groups of driven bevel gears to rotate.

While further improving the drawing quality, it also avoids waste of carriers such as paper and canvas.

[0022] 3. Then, for this auxiliary device for computer drawing, first, a heater provides heat source and is transported to two groups of convex frames through two heat pipes. At the same time, a driving circular gear drives two groups of impellers to rotate through two groups of differential circular gears, generating wind power in the two groups of convex frames. Immediately afterwards, the heat sources in the two groups of convex frames are supplied into two pressurizing elbow pipes. The two heat sources after pressurization treatment converge to the pressurizing main pipe through the telescopic hoses on two three-way connectors, and then are blown to the drawing area through two rows of pressurizing branch pipes arranged in an array through spray nozzles, heating and drying the ink after drawing, and at the same time generating a downward pressure on carriers such as paper and canvas in the drawing area, further improving the flatness of carriers such as paper and canvas during drawing.

And a storage box 21 is fixedly arranged in an array on one side of the bench 1, which is convenient for temporarily storing tools;

[0045] Convex frames 4 are embedded on both sides of the bottom of the bench 1, and an adjustment component and a leveling component for cooperating with the tabletop 2 are respectively arranged on both sides of the inner cavity of the bench 1. The adjustment component includes a servo motor 51 embedded at the center of the bottom of the bench 1, and the leveling component includes a positive and reverse lead screw 62 rotating in a reserved cavity, which performs two-way leveling treatment on carriers such as paper and canvas placed in the placement slots in the tabletop 2, so as to prevent wrinkles and uneven areas on carriers such as paper and canvas, and improve the drawing quality;

[0046] A transmission component is arranged at the top of the inner cavity of the bench 1, and the transmission component includes a second electric push rod 71 embedded in the output shaft of the servo motor 51. Positioning components for cooperating with the placement slots are arranged around the transmission component, and the positioning components include vertical slot openings 81 opened at the four corners of the bench 1, which perform positioning and loosening operations on the four corners of carriers such as paper and canvas after leveling, so as to prevent displacement of carriers such as paper and canvas during automatic drawing, resulting in drawing deviation. While further improving the drawing quality, it also avoids waste of carriers such as paper and canvas.

[0047] As Figures 5-12 shown, the adjustment component further includes a driving circular gear 52 fixed on the output shaft of the servo motor 51, and a driven circular gear 53 is arranged on the outside of the driving circular gear 52. A first electric push rod 54 rotatably matched with the bench 1 is fixedly connected to the top of the driven circular gear 53. The servo motor 51 provides a unified driving source, and the meshing stroke between the two groups of driven circular gears 53 and the driving circular gear 52 is adjusted in place by the two first electric push rods 54. The top of the first electric push rod 54 penetrates through the reserved cavity and is fixedly connected to a driving bevel gear 55, and then the two groups of driving bevel gears 55 drive the positive and reverse lead screws 62 on the two groups of driven bevel gears 61 to rotate;

[0048] The leveling component further includes a driven bevel gear 61 meshing with the top of the driving bevel gear 55 and fixedly connected to the positive and reverse lead screw 62. Threaded sleeves 63 are threadedly connected to both sides of the positive and reverse lead screw 62. A connecting seat 64 slidably matched with the tabletop 2 is fixedly connected to the inner side of the threaded sleeve 63, and a leveling roller 65 for cooperating with the placement slot is rotatably connected to the inner side of the connecting seat 64. The two positive and reverse lead screws 62 drive the two leveling rollers 65 to roll outward in two directions through the connecting seats 64 on the two groups of threaded sleeves 63, and perform two-way leveling treatment on carriers such as paper and canvas placed in the placement slots in the tabletop 2, so as to prevent wrinkles and uneven areas on carriers such as paper and canvas, and improve the drawing quality;

[0049] A horizontal slot opening 11 slidably matched with the connecting seat 64 is opened on the inner side of the tabletop 2, which plays a role in sliding limit for the connecting seat 64. Storage cavities 12 for hiding the leveling rollers 65 are opened on both sides of the tabletop 2, which perform a hiding treatment on the leveling rollers 65, so as to prevent drawing interference with carriers such as paper and canvas.

[0050] The transmission assembly further includes a positioning head 72 fixed to the piston rod of the second electric push rod 71. A driving synchronous pulley 73 is rotatably connected to the center of the inner cavity top of the bench 1. A positioning groove 74 for cooperating with the positioning head 72 is formed at the bottom of the driving synchronous pulley 73. The clamping stroke between the positioning head 72 and the positioning groove 74 is adjusted in place by the second electric push rod 71. The outer side of the driving synchronous pulley 73 is connected with a driven synchronous pulley 75 that is rotationally matched with the bench 1 through a synchronous belt. Then, the driving synchronous pulley 73 drives the four groups of driven synchronous pulleys 75 to rotate accordingly;

[0051] Tightening wheels 13 that are rotationally connected and in synchronous belt transmission cooperation are provided on both sides of the bench 1 close to the driving synchronous pulley 73. Tensioning wheels 14 that are rotationally connected and in synchronous belt transmission cooperation are provided on the other two sides of the bench 1 to tension the synchronous belt, so that the driving synchronous pulley 73 drives the four groups of driven synchronous pulleys 75 to perform stable transmission through the synchronous belt in an orderly manner;

[0052] The positioning assembly further includes a threaded short rod 82 fixed to the bottom of the driven synchronous pulley 75 and rotationally connected to the bench 1. The driving synchronous pulley 73 drives the four threaded short rods 82 to rotate through the four groups of driven synchronous pulleys 75. A threaded sleeve 83 is threadedly connected to the threaded short rod 82. A bent arm 84 that is slidably matched with the vertical slot 81 is fixedly connected to the outer side of the threaded sleeve 83. A rubber head 85 for cooperating with the placement groove is fixedly connected to the side of the bent arm 84 away from the threaded sleeve 83. The four threaded short rods 82 drive the four rubber heads 85 to move up and down through the bent arms 84 on the four groups of threaded sleeves 83 to position and release the four corners of carriers such as paper and canvas after leveling, so as to prevent displacement of carriers such as paper and canvas during automatic drawing, resulting in drawing deviation, further improving the drawing quality and avoiding waste of carriers such as paper and canvas.

[0053] As Figures 13-15 shown, during the automatic drawing of a computer drawing instrument on carriers such as paper and canvas, while the ink cannot be quickly heated and dried, the downward pressure balance effect of carriers such as paper and canvas is also achieved, resulting in contamination of the ink on carriers such as paper and canvas and reducing the drawing quality. Blowing components are provided in both groups of convex frames 4, and air drying components are provided on both sides of the blowing components. The blowing component includes a heater 91 fixed to the chassis 3. Heat pipes 92 communicated with the convex frames 4 are connected to both sides of the heater 91. First, the heater 91 generates heat sources and supplies them into the two groups of convex frames 4 through the two heat pipes 92. Differential circular gears 93 that are rotationally matched with the convex frames 4 are meshed on both sides of the driving circular gear 52. An impeller 94 is fixedly connected to the bottom of the differential circular gear 93 through a fan shaft. Pressurizing elbows 95 are communicated with both sides of the convex frame 4. The driving circular gear 52 drives the two impellers 94 to rotate through the two groups of differential circular gears 93 and conducts the heat sources supplied into the two groups of convex frames 4 into the two pressurizing elbows 95;

[0054] The air-drying component includes a tee joint 101 connected to the top end of the booster elbow 95. The top end of the tee joint 101 is connected to a telescopic hose 102. The top end of the telescopic hose 102 is connected to a booster main pipe 103. The two ends of the booster main pipe 103 are both connected with booster branch pipes 104 in an array. The bottom end of the booster branch pipe 104 is connected to a spray nozzle 105 used in cooperation with the placement groove. The heat sources in the two booster elbows 95 are supplied into the booster main pipe 103 successively through the two tee joints 101 and the telescopic hose 102, and then the ink on carriers such as paper and canvas is quickly heated and air-dried by the spray nozzles 105 on the two rows of arrayed booster branch pipes 104, so as to avoid ink pollution. At the same time, a downward pressure is also applied to carriers such as paper and canvas to further improve the flatness of carriers such as paper and canvas and improve the drawing quality.

[0055] Working principle of an auxiliary device for computer drawing: First, place the paper in the placement groove on the tabletop 2 and below the two leveling rollers 65. First, control the two first electric push rods 54 to start and drive the two groups of driven circular gears 53 to move downward and engage with the meshing part of the driving circular gear 52. Then, control the servo motor 51 to start and drive the two groups of driven circular gears 53 to rotate through the engaged driving circular gear 52. The two groups of driven circular gears 53 drive the two groups of driving bevel gears 55 to rotate through the two first electric push rods 54. The two groups of driving bevel gears 55 drive the forward and reverse lead screws 62 on the two groups of driven bevel gears 61 to rotate. The two forward and reverse lead screws 62 drive the two screw sleeves 63 to move outward synchronously. The two screw sleeves 63 drive the two leveling rollers 65 to roll outward bidirectionally along the placement groove through the two connecting seats 64, and roll and level from the middle of the paper to both sides until the two leveling rollers 65 move outward to the two storage cavities 12. First, control the servo motor 51 to pause, and then control the two first electric push rods 54 to close and drive the two groups of driven circular gears 53 to move upward to disengage from the meshing part of the driving circular gear 52 to the initial position;

[0056] Next, the second electric push rod 71 is controlled to open and drive the positioning head 72 to move up and clamp it in the positioning groove 74 in the driving synchronous wheel 73, and then the servo motor 51 is controlled to open again and drive the driving synchronous wheel 73 to rotate through the positioning head 72 and the positioning groove 74 that are clamped in place. Under the transmission cooperation of the two sets of abutting wheels 13 and the tensioning wheel 14 to the synchronous belt, the driving synchronous wheel 73 drives the threaded short rods 82 on the four sets of driven synchronous wheels 75 to rotate through the synchronous belt, and the four threaded short rods 82 drive the four sets of threaded sleeves 83 to move downward accordingly, and the four sets of threaded sleeves 83 drive the four sets of rubber heads 85 to move downward to the four ends of the paper in the placement slot through the four bent arms 84. After positioning the four corners of the flattened paper, first control the servo motor 51 to pause, then control the second electric push rod 71 to close and drive the positioning head 72 to move downward to disengage from the positioning groove 74 in the driving synchronous wheel 73 to the initial position, then control the two X-axis electric slide rails 15 to open and drive the X-axis electric slide rail slide 16 to perform X-axis axial displacement, and control the Z-axis electric slide rail 17 to open and drive the Z-axis electric slide rail slide 18 to perform Z-axis axial displacement, and then control the electric telescopic rod 19 to drive the drawing pen 20 to perform Y-axis axial displacement, so that the drawing pen 20 with the three-axis displacement of X-axis, Z-axis and Y-axis automatically draws on the flattened and positioned paper;

[0057] When the drawing pen 20 is automatically drawing on the flattened and positioned paper, the heater 91 is first controlled to turn on and supply the generated heat source into the two groups of protrusions 4 through the two heat transfer pipes 92, and then the servo motor 51 is continuously turned on and drives the two groups of differential circular gears 93 to rotate through the driving circular gear 52. The two groups of differential circular gears 93 drive the two impellers 94 to rotate in the two groups of protrusions 4 and generate wind pressure, and then the heat source supplied to the two groups of protrusions 4 is supplied to the two boosting elbows 95. Then, the heat source in the two boosting elbows 95 is successively gathered by the telescopic hoses 102 on the two three-way joints 101 to the boosting main pipe 103, and then the jet nozzles 105 on the boosting branch pipes 104 distributed in two rows of arrays heat and air-dry the drawing area of ​​the drawing pen 20 to avoid ink contamination, and also generate downward pressure on the paper in the drawing area to assist in leveling the paper until the drawing pen 20 completes the automatic drawing work.

The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
