[0008] Preferably, the fourth pulley and the outer wall of the second pulley are sleeved with a belt, and the third pulley and the outer wall of the first pulley are sleeved with a belt.

[0009] Preferably, the ventilation groove is arranged on the inner wall and is communicated with the rear side of the bottom of the frame-shaped square tube, and is used for air flow.

[0010] Preferably, the limiting assembly comprises a pull rod, the pull rod is slidingly connected to the top left end of the drawing table, the top left end of the drawing table is provided with a locking groove, the bottom of the pull rod is fixedly connected with a connecting block, the bottom of the connecting block is fixedly connected with a rubber block, and the inner wall left end of the drawing table is provided with a plurality of second springs.

[0011] Preferably, a plurality of the second springs are arranged on the top of the connecting block.

[0012] Preferably, the inclination assembly comprises a positioning block, the positioning block is fixedly connected to the bottom front end of the drawing table, one side of the positioning block is rotatably connected with a supporting leg, the front side of the supporting leg is rotatably connected with a rotating ring, the rear side of the rotating ring is fixedly connected with a first bevel gear, the inner wall of the supporting leg is fixedly connected with a limiting plate, the inner wall of the limiting plate is rotatably connected with a lead screw, the bottom of the lead screw is fixedly connected with a second bevel gear, the outer wall of the lead screw is threadedly connected with a threaded sleeve, and the second bevel gear and the first bevel gear are in meshing connection.

[0013] Preferably, the threaded sleeve is arranged at the bottom rear side of the drawing table, and the supporting leg is slidingly connected to the bottom rear side of the drawing table.

[0014] Preferably, the rubber block is slidingly connected to the inner wall of the locking groove.

[0015] Preferably, the clockwork spring comprises a center connecting point and an outer wall connecting point, the center connecting point is fixedly connected with the rotating rod, and the outer wall connecting point is fixedly connected with the inner wall of the clamping block, and is used for driving the rotating rod to complete the reverse winding.

[0016] Working principle: when the user uses the packaging design auxiliary drawing device to design a drawing, first adjust the inclination angle of the drawing table according to personal use preference; first rotate the rotating rings on both sides, then drive the first bevel gear and the second bevel gear to be in meshing connection through the rotating rings, so as to drive the lead screw to rotate and push up through the threaded connection, lift the rear side of the drawing table, and drive the rotating connection between the bottom positioning block of the drawing table and the supporting leg, so as to complete the angle adjustment.

[0017] After the debugging is completed, the drawing paper wound on the outer wall of the rotating rod can be inserted into the reserved slot on one side of the top of the drawing table, and the connection of the rotating rod and the first belt pulley is completed by inserting the square quick release block. When the user pulls the drawing paper on the outer surface of the rotating rod to the left limiting assembly on the top of the drawing table, the rotating rod rotates and reversely rotates the connected clockwork springs on both sides, so that the clockwork springs have reverse rotation stress. In the process of rotating the rotating rod, the fan installed inside the air guide plate at the bottom of the drawing table can be rotated through the transmission assembly. At this time, according to the forward rotation and reverse rotation of the fan, two effects are generated. When the driving locking slot is forward rotated during the laying of the drawing paper, the air passage is communicated through the air passage, the frame square tube and the air inlet hole, so that the downward micro-suction effect of the plurality of air inlets is realized. Thus, the laying of the drawing paper and the fitting effect of the drawing table top are improved during the laying process, thereby reducing manual arrangement and improving use efficiency. When the drawing paper is cut after use, the clockwork spring reversely rotates the rotating rod, thereby automatically recycling unused drawing paper. At this time, the force transmission of the transmission assembly will make the fan reverse rotation, so that the upward air force is realized at multiple positions on the top of the drawing table through the frame square tube and the plurality of air inlets, thereby improving the drying speed of the drawing paper and ink, and avoiding the problem of adhesion of the drawing paper and the top of the drawing table caused by the penetration of part of the ink stain.

[0018] The application provides an auxiliary drawing device for packaging design. The device has the following advantages: 1. The device combines the fan, air guide plate, air passage and frame square tube to tightly fit the drawing paper on the surface of the drawing table through micro-suction during the laying of the drawing paper, effectively avoiding the wrinkling, displacement or loosening of the drawing paper during drawing, significantly improving the stability of the drawing paper, reducing the time of manual arrangement, ensuring the accuracy of drawing operation and meeting the requirements of high-precision drawing.

[0019] 2. The design of the clockwork spring and the rotating rod enables the drawing paper to be automatically laid and recycled through rotation. The drawing paper can be automatically unfolded and fixed during the laying process, and the unused part of the drawing paper can be automatically recycled through reverse rotation of the rotating rod and reverse pulling force of the clockwork spring after drawing. This function reduces manual intervention and makes the operation process more simple and efficient, significantly improving the use efficiency of the drawing device and user experience.

[0020] 3. The device realizes upward air output after drawing through reverse rotation of the fan, and the ink can be quickly dried through the uniform distribution of the air inlets, avoiding the problems of drawing paper pollution and adhesion of the drawing paper and the drawing table caused by ink marks. This function not only reduces the drawing defects caused by ink diffusion, but also further improves the quality of the drawing product, which is suitable for packaging design scenarios that require high efficiency and high quality drawing output.

[0024] Example 1: Please refer to the drawings of the present application Figure 1 , the drawings of the present application Figure 4 , the drawings of the present application Figure 6The embodiment of the present application provides an auxiliary drawing device for packaging design, which comprises a drawing table 2, a plurality of clamping blocks 4 are slidably connected to the top of the drawing table 2, a rotating rod 5 is rotatably connected to the side of the two adjacent clamping blocks 4, a spring 6 is mounted on the outer wall of the rotating rod 5, and the spring 6 is mounted on the inner wall of the clamping block 4. A gas guide plate 7 is fixedly connected to the bottom of the rear side of the drawing table 2, an extension plate 10 is fixedly connected to the rear side of the drawing table 2, a quick release block 14 is slidably connected to one end of the outer wall of the rotating rod 5, and a transmission assembly is arranged on the outer wall of the quick release block 14.

[0025] Please refer to the accompanying drawings Figure 2 , the accompanying drawings Figure 3 , a fan 16 is mounted on one side of the transmission assembly, a plurality of air grooves 17 are formed in the inner wall of the gas guide plate 7, a frame-shaped square tube 8 is mounted on the top of the drawing table 2, a plurality of air supply holes 9 are formed in the top of the frame-shaped square tube 8, a limiting assembly is arranged on the left side of the top of the drawing table 2, and an inclination assembly is arranged on the bottom of the drawing table 2.

[0026] The top edge of the air groove 17 is connected to the bottom rear side of the frame-shaped square tube 8, and is used for airflow passing.

[0027] Specifically, the device comprises a working platform mainly formed of a drawing table 2, and a plurality of clamping blocks 4 are slidably connected to the top of the drawing table 2. One side of the two adjacent clamping blocks 4 is connected with a rotating rod 5 through a rotating connecting piece, the rotating rod 5 can rotate along the axis, and a spring 6 is mounted on the outer wall of the rotating rod 5. The spring 6 is mounted on the inner wall of the clamping block 4, and functions to generate tension and retraction force through forward and reverse rotation of the rotating rod 5, so as to realize automatic spreading and recycling of the drawing paper, thereby reducing manual operation and improving work efficiency.

[0028] The bottom of the rear side of the drawing table 2 is fixedly connected with a gas guide plate 7. A plurality of air grooves 17 are formed in the inner wall of the gas guide plate 7, the air grooves 17 are in communication with the air duct of the gas guide plate 7, and can guide airflow to flow along a preset path. The rear side of the drawing table 2 is fixedly connected with an extension plate 10, the extension plate 10 is used for providing additional support and mounting space, and is used for mounting components such as a transmission assembly. One end of the rotating rod 5 is slidably connected with a quick release block 14, the quick release block 14 can quickly disassemble and assemble the rotating rod 5, and improves the maintenance convenience of the equipment. The outer wall of the quick release block 14 is provided with a transmission assembly, the transmission assembly realizes power transmission through a belt and a belt pulley, and a fan 16 is mounted on one side of the transmission assembly. The fan 16 functions to generate airflow through rotation, and is combined with the air grooves 17 and the frame-shaped square tube 8 to adjust the adhesion of the drawing paper and the drying effect of the ink during drawing.

[0029] Please refer to the accompanying drawings Figure 4The top of the drawing table 2 is provided with a frame-shaped square tube 8, which is internally hollow and uniformly provided with a plurality of air outlet holes 9 on the top. These air outlet holes 9 are used to output air flow. During the drawing process, in combination with the suction effect generated by the forward rotation of the fan 16, a micro-suction force is applied downward through the air vent groove 17 and the air outlet hole 9, so that the drawing paper can be tightly attached to the surface of the drawing table 2, thereby avoiding wrinkles or movement of the drawing paper and significantly improving the drawing accuracy. When the drawing paper is completed, the fan 16 is reversed, and the upward air force is output through the air outlet hole 9, thereby accelerating the drying of the ink on the surface of the drawing paper and avoiding ink diffusion or pollution.

[0030] The top edge of the air vent groove 17 is connected to the bottom rear side of the frame-shaped square tube 8, so that the air flow can be effectively circulated between the air guide plate 7 and the frame-shaped square tube 8. Through the guidance of the air vent groove 17, the air flow is uniformly distributed at the air outlet hole 9, ensuring that the entire surface of the drawing table 2 is uniformly affected by the air flow, whether it is the suction function or the drying function, which can be efficiently realized.

[0031] Please refer to the accompanying drawings Figure 4 - the accompanying drawings Figure 5 The transmission assembly includes a first pulley 11 mounted on the outer wall of the quick release block 14. The inner wall of the extension plate 10 is rotatably connected with a third pulley 13, and the rear side of the third pulley 13 is fixedly connected with a second pulley 12. The inner wall of the air guide plate 7 is rotatably connected with a fourth pulley 15. The outer wall of the fourth pulley 15 and the second pulley 12 is sleeved with a belt, and the outer wall of the third pulley 13 and the first pulley 11 is sleeved with a belt.

[0032] Specifically, the transmission assembly includes a first pulley 11, a second pulley 12, a third pulley 13 and a fourth pulley 15. The first pulley 11 is mounted on the outer wall of the quick release block 14 and connected with the rotating rod 5 through the quick release block 14. The rotating rod 5 drives the rotation of the first pulley 11 by manual or mechanical rotation during use. The inner wall of the extension plate 10 is rotatably connected with a third pulley 13, and the rear side of the third pulley 13 is fixedly connected with a second pulley 12. The inner wall of the air guide plate 7 is rotatably connected with a fourth pulley 15, which is used to cooperate with the second pulley 12.

[0033] In order to realize power transmission, the fourth pulley 15 and the outer wall of the second pulley 12 are sleeved with a belt, so that they can rotate synchronously. Similarly, the outer wall of the third pulley 13 and the first pulley 11 are also connected by a belt, so that the rotating power of the rotating rod 5 is transmitted to the third pulley 13 through the first pulley 11, and further transmitted to the fourth pulley 15 through the linkage of the second pulley 12 and the fourth pulley 15 to realize the operation of the entire device.

[0034] In actual work, when the rotating rod 5 rotates in the positive direction, the power transmitted through the belt pulley system drives the fan 16 to rotate in the positive direction, generating a downward airflow effect. This airflow forms a micro-suction through the air guide groove 17 of the air guide plate 7 and the air conveying hole 9 of the frame-shaped square tube 8, so that the drawing paper laid on the surface of the drawing table 2 is tightly attached, avoiding the phenomenon of wrinkling or displacement, thereby improving the flatness and quality of the drawing.

[0035] Conversely, when the rotating rod 5 rotates in the reverse direction, the belt pulley system drives the fan 16 to rotate in the reverse direction, generating an upward airflow effect. Through the action of the air guide groove 17 and the air conveying hole 9, the upward airflow can quickly dry the ink on the surface of the drawing paper, avoiding the occurrence of ink spreading or sticking phenomenon, thereby further improving the drawing quality and use efficiency.

[0036] Please refer to the accompanying Figure 1 , the accompanying Figure 7 , the limiting assembly includes a pull rod 19, which is slidingly connected to the top left end of the drawing table 2. The top left end of the drawing table 2 is provided with a locking groove 18. The bottom of the pull rod 19 is fixedly connected with a connecting block 20. The bottom of the connecting block 20 is fixedly connected with a rubber block 22. The inner wall left end of the drawing table 2 is provided with a plurality of second springs 21. The plurality of second springs 21 are arranged on the top of the connecting block 20.

[0037] The rubber block 22 is slidingly connected to the inner wall of the locking groove 18.

[0038] Specifically, the limiting assembly includes a pull rod 19, which is slidingly connected to the top left end of the drawing table 2. The sliding installation mode enables it to be flexibly adjusted in position during use. The top left end of the drawing table 2 is provided with a locking groove 18, which provides a guide path for the movement of the pull rod 19, ensuring the stability and accuracy of its sliding.

[0039] The bottom of the pull rod 19 is fixedly connected with a connecting block 20, and the bottom of the connecting block 20 is further fixedly connected with a rubber block 22. The rubber block 22 is slidingly connected to the inner wall of the locking groove 18, which increases the friction force of the contact surface, effectively avoiding the loosening phenomenon during sliding. At the same time, the elastic properties of the rubber block 22 can absorb the impact force of the pull rod 19 during operation, prolonging the service life of the device and improving the stability of the operation.

[0040] The inner wall left end of the drawing table 2 is provided with a plurality of second springs 21, which are installed on the top of the connecting block 20 to provide an upward restoring force for the pull rod 19. When the pull rod 19 is pressed down during use, the second springs 21 are compressed; when the external force is removed, the second springs 21 release the elastic potential energy, thereby resetting the pull rod 19 to the initial position. This design enables the limiting assembly to automatically reset when not in use, facilitating subsequent operation and further improving the operation efficiency of the device.

[0041] In operation, the user adjusts the position of the pull rod 19 by pulling or pressing, so that the connecting block 20 and the rubber block 22 enter the specific position of the inner wall of the locking groove 18, thereby realizing the limiting function of each part of the drawing table 2. For example, when the starting position of the laid paper needs to be fixed, the pull rod 19 drives the connecting block 20 and the rubber block 22 to realize precise limiting through the guidance of the locking groove 18, ensuring that the paper remains stable during laying and does not shift or loosen.

[0042] Please refer to the attached Figure 8 The inclined assembly comprises a positioning block 3 fixedly connected to the bottom front end of the drawing table 2, one side of the positioning block 3 being rotatably connected to a support leg 1, the front side of the support leg 1 being rotatably connected to a rotating ring 23, the rear side of the rotating ring 23 being fixedly connected to a first bevel gear 24, the inner wall of the middle of the support leg 1 being fixedly connected to a limiting plate 26, the inner wall of the limiting plate 26 being rotatably connected to a lead screw 27, the bottom of the lead screw 27 being fixedly connected to a second bevel gear 25, the outer wall of the lead screw 27 being threadedly connected to a threaded sleeve 28, and the second bevel gear 25 being meshingly connected to the first bevel gear 24.

[0043] The threaded sleeve 28 is hingedly connected to the bottom rear side of the drawing table 2, and the support leg 1 is slidingly connected to the bottom rear side of the drawing table 2.

[0044] Specifically, the inclined assembly comprises a positioning block 3 fixedly connected to the bottom front end of the drawing table 2, for providing a stable mounting base for the support structure. One side of the positioning block 3 is connected to a support leg 1 through a rotating connector, and the support leg 1 can freely rotate at the connection, thereby providing the drawing table 2 with the ability to adjust the support angle. The front side of the support leg 1 is further connected to a rotating ring 23 through a rotating connector, and the rear side of the rotating ring 23 is fixedly connected to a first bevel gear 24. This design enables the support leg 1 to form a linkage structure with the rotating ring 23 and the first bevel gear 24 during angle adjustment, ensuring the stability and accuracy of angle adjustment.

[0045] The inner wall of the middle of the support leg 1 is fixedly connected to a limiting plate 26, which provides mounting and rotating support for the lead screw 27. The inner wall of the limiting plate 26 is connected to a lead screw 27 through a transmission connector, and the bottom of the lead screw 27 is fixedly connected to a second bevel gear 25. The first bevel gear 24 and the second bevel gear 25 are meshingly connected to form a transmission system. When the rotating ring 23 is rotated, the first bevel gear 24 drives the second bevel gear 25 to rotate synchronously through meshing, thereby driving the lead screw 27 to rotate.

[0046] The outer wall of the lead screw 27 is threadedly connected with a threaded sleeve 28, which can move along the axial direction of the lead screw 27. The threaded sleeve 28 is hinged at the bottom rear side of the drawing table 2, and the precise adjustment of the height of the rear part of the drawing table 2 is realized through the sliding connection of the support leg 1. Specifically, when the lead screw 27 rotates, the threaded sleeve 28 moves axially along the thread, thereby driving the bottom rear side of the drawing table 2 to rise or fall, realizing the adjustment of the overall angle of the drawing table 2. The bottom of the support leg 1 is slidingly connected to the rear side of the drawing table 2, so that it can flexibly adapt to the change in the height of the drawing table 2 during the adjustment process, ensuring the smoothness and stability of the adjustment process.

[0047] Example 2: Detail drawing of multi-layer packaging design paper In the multi-layer packaging design work, the designer first needs to draw the packaging paper of each layer (such as the outer packaging pattern and the inner layer text layout) independently. When using the device, the designer can adjust the angle of the drawing table 2 through the tilt assembly according to the design requirements of the current paper, so that it can adapt to the best operating posture for detail drawing. The multi-angle adjustment function provided by the tilt assembly ensures the comfort and efficiency of the drawing table 2.

[0048] Then, the designer lays the current design paper on the drawing table 2, roughly positions the paper through the sliding block 4, and starts the micro-suction function of the device. The fan 16 forms a uniform suction air flow on the surface of the drawing table 2 through the ventilation slot 17 and the air outlet hole 9, so that the paper adheres to the table, avoiding the influence of the accuracy of the lines due to the sliding of the paper. For the part that needs high-precision superposition in multi-layer design, the micro-suction function is especially helpful for the flat positioning of the paper, ensuring the alignment of the marks between each layer of paper and reducing errors.

[0049] After the drawing is completed, the designer can directly start the reverse function of the fan 16 of the device, output upward drying air flow through the air outlet hole 9, quickly dry the ink on the paper, especially suitable for complex patterns with multi-color superposition, avoiding ink diffusion or pollution of adjacent layers. This function significantly improves the efficiency and quality of the detail drawing of the packaging design.

[0050] When the content of the paper needs to be adjusted, the designer can use the automatic recycling function of the device to rewind the current design paper part through the linkage of the rotating rod 5 and the clockwork spring 6, and quickly expand the next layer of design paper for modification. This continuous paper management method is especially suitable for the process operation of multi-layer packaging design.

[0051] Through the above-mentioned embodiments, the application can provide efficient and accurate drawing management and drawing solutions for multi-layer packaging structures in the field of packaging design. The multifunctional design of the device ensures the efficiency and smoothness of the designer in each layer of drawing, modification, ink drying, and subsequent adjustment, thereby meeting the complex needs of multi-layer packaging design and further improving the overall efficiency of the packaging design process and the quality of the finished product.

[0052] Although embodiments of the application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
