Description

Technical Field

[0001] The present invention relates to the technical field of Internet teaching tools, in particular to a digital creative drawing machine. Background Art

[0002] In the fields of education and demonstration, with the advancement of digital technology and the popularization of the Internet, the intelligentization and networking of teaching aids have become an important trend in improving classroom interactivity and teaching efficiency. Educational or demonstration aids, especially digital creative devices used for teaching, can achieve online acquisition, drawing and sharing of creative patterns by combining Internet functions, helping teachers to quickly generate visual teaching materials in the classroom, such as geometric figures, art templates or design patterns on cardboard, for mathematics, art or engineering teaching. However, existing teaching drawing devices are usually limited to local operation and lack the ability to obtain diverse motion paths and creative patterns in real time through the Internet, making it difficult for teachers to flexibly adapt to different teaching needs.

[0003] In the existing technology, educational or demonstration tools have significant deficiencies in cardboard drawing and cutting. On the one hand, existing equipment cannot effectively record and share different cutting paths. Teachers often need to manually repeat the drawing when preparing teaching materials, resulting in low efficiency and poor pattern consistency. On the other hand, the drawing and cutting process lacks integrated control, which easily leads to inaccurate drawing of different types of patterns on cardboard. The cut materials are difficult to use directly for teaching demonstrations, such as generating slice models or templates for classroom interaction, which affects teaching effectiveness and student participation. In addition, existing Internet integrated teaching tools mostly remain at the simple data transmission level, and cannot realize the automatic recording of motion paths, uploading to the cloud for sharing, and on-demand acquisition, which limits their application in distributed education environments (such as online teaching or resource sharing platforms).

[0004] In response to the above problems, the present invention provides a digital creative drawing machine, which uses a control unit to realize the functions of obtaining different motion paths and creative patterns from the Internet, automatically drawing, and recording and uploading them for cloud sharing. It solves the difficult problem of realizing different types of drawing on cardboard by recording different cutting paths, thereby generating accurate teaching materials after cutting for teachers to use in education or demonstration activities, thereby improving the intelligence level and practicality of teaching tools.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0022] like Figures 1 to 13As shown, the digital creative drawing machine includes a housing 1, a driving component 2, a fixing component 3, a first positioning mechanism 4, and a guide mechanism 6. The driving component 2, fixing component 3, first positioning mechanism 4, and guide mechanism 6 are all mounted on the housing 1. The driving component 2 is used to drive the fixing component 3 to move along the length of the housing 1. The fixing component 3 is used to fix the pen refill. The first positioning mechanism 4 and guide mechanism 6 are arranged in a corresponding vertical direction and together guide the paper. The direction of paper movement is perpendicular to the direction of movement of the pen refill on the fixing component 3 driven by the driving component 2. The driving component 2 consists of a second motor 201, two synchronous pulleys 202, and a synchronous belt 203. The output end of the second motor 201 is connected to one of the synchronous pulleys 202. The two synchronous pulleys 202 transmit power via the synchronous belt 203. The protruding shafts on the two synchronous pulleys 202 are rotatably connected to the housing 1. The protective housing 301 is connected to the synchronous belt 203. The reciprocating rotation of the second motor 201 drives the protective housing 301 to reciprocate on the synchronous belt 203 to achieve drawing.

[0023] In this embodiment, a control unit 8 is mounted on the housing 1 and is used to acquire different motion paths and creative patterns via the internet, automatically control the drawing process, and record and share the drawn motion paths, thereby enabling intelligent and networked operation of the digital creative drawing machine. The control unit 8 comprises a processor, a storage module, an input interface, an output interface, a communication module, and a power module. The processor is electrically connected to the storage module, the input interface, the output interface, and the communication module to process and execute the motion paths and related control instructions. The input interface is used to receive user-entered control instructions or parameters. The output interface is electrically connected to the motors of the drive components and guide mechanism to output control signals. The communication module supports internet connectivity for acquiring and uploading motion paths and creative patterns. The power module provides a stable power supply for the control unit 8.

[0024] The control unit 8 is preferably integrated within or on the side of the housing 1 and utilizes an embedded microcontroller (such as an ARM or STM32 series processor) as its processor to achieve efficient data processing and real-time control. The storage module, which can be flash memory or EEPROM, is used to store the motion path and creative pattern acquired via the communication module, as well as locally recorded drawing path data. The motion path includes the refill's two-dimensional coordinate data, movement speed, and starting and ending points. Creative patterns include geometric shapes, art templates, or other educational patterns, suitable for educational or demonstration activities. The input interface supports a touch screen or USB port, allowing users to manually input parameters or select preset patterns. The communication module supports Wi-Fi, Bluetooth, or Ethernet connectivity, enabling access to a variety of motion paths and creative patterns from cloud servers, online teaching platforms, or mobile applications via the internet. Locally drawn motion paths can also be uploaded to the cloud for storage and sharing. The output interface includes a digital I / O port or a PWM signal output, which is used to send precise position control signals to the drive component's motor and rotational speed control signals to the guide mechanism's motor to achieve coordinated movement of the refill and paper. The power module is preferably a regulated power supply circuit, supporting battery or external power to ensure stable drawing and data transmission.

[0025] The operating principle of control unit 8 is based on a closed-loop control system: the processor obtains the motion path and creative pattern from the cloud via the communication module, or reads locally stored path data from the storage module. Using a path planning algorithm (such as interpolation or PID control), the path data is converted into motor control instructions. These instructions are then sent via an output interface to the drive component's motor, which controls the movement of the refill along the length of the housing, and to the guide mechanism's motor, which drives the paper vertically, enabling the automatic drawing of the creative pattern. During the drawing process, the processor records the actual movement path of the refill and paper in real time, generates a path data file, and uploads it to a cloud server via the communication module for download and reuse by other users or devices. Control unit 8 can also integrate sensor feedback interfaces (such as limit sensors connected to fixed components or encoders on the guide mechanism) to monitor the refill position and paper transport status in real time, dynamically adjusting control parameters to ensure drawing accuracy.

[0026] In actual use, the operator inputs drawing task parameters (such as pattern type, path coordinates, and transmission speed) into the control unit 8 via the input interface or communication module, or retrieves a preset creative pattern (such as a geometric figure or art template for teaching) from the cloud via the internet. The processor initializes the system based on the acquired motion path, generates a control signal, and drives the motor of the drive component via the output interface, causing the pen refill on the fixed component to move along the predetermined path to complete the drawing. Simultaneously, the motor of the guide mechanism is controlled to drive the paper to be smoothly transported in the vertical direction. After the drawing is completed, the processor records the actual motion path, generates a data file, and uploads it to the cloud via the communication module for sharing teaching resources or cross-device reuse. The entire process requires no human intervention. Through internet connection, path recording, and cloud sharing functions, the control unit 8 ensures intelligent and efficient drawing, suitable for generating teaching materials required for educational activities or demonstrations.

[0027] The guide mechanism 6 includes a main shaft 601 and multiple knurls 602; the main shaft 601 is rotatably connected to the housing 1, and the multiple knurls 602 are processed on the main shaft 601 and correspond one-to-one with the multiple round rollers 402; the paper passes between the round rollers 402 and the main shaft 601. The arrangement of the knurls 602 increases the friction between the round rollers 402 and the main shaft 601, thereby avoiding slipping when transporting the paper.

[0028] The first positioning mechanism 4 includes multiple shells 401, multiple frames 403, multiple round rollers 402, a beam 404, a contact plate 405, a bracket 406, a handle 407, an axle 408, a tension spring 410, a connecting rod 412, a round wheel 409 and a round groove 411; the multiple shells 401 are fixedly connected to the casing 1, the frame 403 is rotatably connected to the casing 1, and the round roller 402 is rotatably connected to the frame 403. The crossbeam 404 is fixedly connected to the frame 403, the crossbeam 404 is fixedly connected to the contact plate 405, the connecting rod 412 can contact the contact plate 405, the connecting rod 412 is fixedly connected to the shaft 408, the shaft 408 is rotatably connected to the bracket 406, the bracket 406 is fixedly connected to the casing 1, the shaft 408 is fixedly connected to the handle 407, and the two ends of the tension spring 410 are respectively connected to the bracket 406 and the contact plate 405; the side of the connecting rod 412 close to the contact plate 405 is rotatably connected to the round wheel 409; the circular groove 411 is processed on the upper surface of the contact plate 405 and matches the size of the round wheel 409.

[0029] The fixing component 3 may include a clamping device for detachably fixing the pen core to ensure the stability of the pen core during the drawing process.

[0030] The first positioning mechanism 4 and the guide mechanism 6 together form a paper transport path. Multiple housings 401 are evenly distributed along the length of the housing 1 and serve to support a frame 403. The frame 403 can be rotatably connected to the housing 1 via a hinge or bearing, allowing it to swing relative to the housing 1. The circular roller 402 is preferably a smooth-surfaced roller, rotatably connected to the frame 403 via a bearing to reduce frictional damage to the paper.

[0031] The main shaft 601 of the guide mechanism 6 is driven by a motor. The knurling 602 is a raised structure with a textured surface that increases friction with the paper, thereby driving the paper forward perpendicular to the direction of movement of the pen refill. The circular roller 402 is vertically aligned with the knurling 602. As the paper passes through, the circular roller 402 provides a pressing force, ensuring close contact between the paper and the knurling 602, ensuring smooth conveyance.

[0032] Furthermore, when the handle 407 is in the high position, the tension spring 410 relies on its own elastic deformation to keep the contact plate 405 in its initial position, and the circular wheel 409 on the connecting rod 412 contacts the upper surface of the contact plate 405. At this time, the circular roller 402 is pressed against the main shaft 601 through the linkage of the crossbeam 404 and the frame 403, applying a pressing force to the paper. When the operator presses down on the handle 407, the handle 407 drives the shaft 408 to rotate, thereby causing the connecting rod 412 to swing, and the circular wheel 409 slides along the upper surface of the contact plate 405 and snaps into the circular groove 411. The structural design of the circular groove 411 ensures that the circular wheel 409 can automatically position after snapping, so that the handle 407 remains in the pressed position without the operator having to hold it continuously. The contact plate 405 rotates and drives the frame 403 and the circular roller 402 to rise through the crossbeam 404, and the circular roller 402 separates from the main shaft 601, facilitating the insertion or removal of paper. The tension spring 410 is stretched when the contact plate 405 rotates to provide a reset force. When the operator operates the handle 407 again to disengage the round wheel 409 from the round groove 411, the tension spring 410 drives the contact plate 405 to reset, and the round roller 402 presses the paper again.

[0033] In actual use, the operator first fixes the pen core 306 on the fixed component 3; then, presses down the handle 407, driving the shaft 408 and the connecting rod 412 to rotate, so that the round wheel 409 is clamped into the round groove 411 of the contact plate 405. The contact plate 405 rotates and lifts the frame 403 and the round roller 402 through the crossbeam 404. The clamping structure of the round wheel 409 and the round groove 411 makes the handle 407 automatically positioned, without the need to hold it continuously. At this time, the round roller 402 is lifted to facilitate the insertion of paper, and then the paper is placed on the round roller 409. 02 and the main shaft 601; the operator lifts handle 407 upward again to disengage the circular wheel 409 from the circular groove 411. The restoring force of tension spring 410 returns contact plate 405 to its original position, and circular roller 402 presses down and presses the paper against the main shaft 601; the drive source of drive component 2 and guide mechanism 6 is activated, and fixed component 3 drives the pen core 306 along the length of the housing 1 to draw. At the same time, the main shaft 601 rotates, driving the paper forward smoothly in a direction perpendicular to the movement of the pen core, realizing the automatic drawing of digital creative drawings. This adjustment mechanism, through the locking and positioning design of tension spring 410 and circular wheel 409 with circular groove 411, ensures that the pressing and lifting actions of circular roller 402 are accurate and reliable, and the operation is convenient. It avoids deviation or jamming of the paper during transportation, and improves the efficiency and quality of drawing.

[0034] In this embodiment, the fixing component 3 includes a protective shell 301, a connecting plate 302, a pen barrel 303, a refill 306, a clamping head 304, a screw 310, a cap 305, at least three trapezoidal blocks 308, an inner cylinder 309, and an outer cylinder 307. The protective shell 301 is fixedly connected to the driving component 2 for receiving the driving force of the driving component 2; the protective shell 301 is fixedly connected to the connecting plate 302, which is slidably connected to the pen barrel 303; the refill 306 is disposed inside the pen barrel 303 and is slidably connected to the pen barrel 303; the connecting plate 302 is threadedly connected to the screw 310; the clamping head 304 is slidably connected to the screw 310; and the cap 305 is threadedly connected to the screw 310. One side of the cap 305 can press against the clamping head 304, so that the clamping head 304 is in close contact with the pen barrel 303 to fix the refill 306. Preferably, a micro electric push rod is provided inside the protective shell 301 to control the lifting and lowering of the pen core 306 and other structures, so as to lift the pen core 306 in places where drawing is not required.

[0035] The fixing member 3 further includes at least three trapezoidal blocks 308, an inner cylinder 309, and an outer cylinder 307. The inner cylinder 309 is fixedly connected to the pen barrel 303, and the at least three trapezoidal blocks 308 are rotatably connected to the inner wall of the inner cylinder 309 via a hinge mechanism. The outer cylinder 307 is threadedly connected to the outer wall of the inner cylinder 309. The outer cylinder 307 can contact and drive the at least three trapezoidal blocks 308 to approach each other through rotation. The at least three trapezoidal blocks 308 approaching each other can clamp the pen refill 306.

[0036] In this embodiment, the fixing member 3 uses a multi-stage clamping mechanism to ensure stable fixation of the refill 306. The connecting plate 302 is a flat plate structure with a guide groove or slide rail that allows the pen barrel 303 to slide vertically to adjust the height of the refill 306 relative to the paper.

[0037] The pen barrel 303 is a hollow cylindrical structure that houses the pen refill 306. A sliding fit allows the refill 306 to be fine-tuned within the barrel 303 to accommodate different drawing needs. A screw 310 is threadedly connected to the connecting plate 302. Rotating the screw 310 drives the clamping head 304 to move axially along the screw 310. The clamping head 304 is preferably conical or flat, with one end capable of tightly abutting the end of the pen barrel 303. A cap 305 is threadedly attached to the end of the screw 310. Rotating the cap 305 forces it into contact with the clamping head 304, thereby applying pressure to the pen barrel 303 and ensuring the stability of the refill 306 during drawing.

[0038] Furthermore, the inner cylinder 309 is fixedly connected to the barrel 303 via threads or snaps. At least three trapezoidal blocks 308 are evenly distributed on the inner wall of the inner cylinder 309 and are rotatably connected via an articulated mechanism (such as a hinge or pin). The inner surfaces of the trapezoidal blocks 308 are preferably provided with a high-friction material (such as a rubber pad or silicone layer) to enhance the grip on the refill 306. The outer cylinder 307 is threadedly connected to the outer wall of the inner cylinder 309. Rotating the outer cylinder 307 causes it to move axially along the inner cylinder 309, thereby squeezing the outer inclined surfaces of the trapezoidal blocks 308, driving the trapezoidal blocks 308 to rotate about the hinge point and approach each other, ultimately clamping the refill 306. This multi-point clamping design accommodates refills 306 of varying diameters (such as standard ballpoint pen refills or drawing pen refills) and ensures stability during high-speed movement, preventing deviation or jitter.

[0039] During actual use, the operator first inserts the refill 306 into the pen barrel 303 and rotates the outer barrel 307, causing at least three trapezoidal blocks 308 to rotate about the hinge point and clamp the refill 306. Next, the operator rotates the screw 310 and cap 305, forcing the clamping head 304 against the pen barrel 303 to further secure the refill 306. Finally, the protective housing 301 is connected to the drive component 2, which is activated to drive the fixing component 3 along the length of the housing 1, allowing the refill 306 to accurately draw on paper. The fixing component 3, through its dual clamping mechanism (clamping head 304 and trapezoidal blocks 308), ensures the stability and drawing accuracy of the refill 306. It also facilitates the installation and replacement of the refill, adapting to various drawing needs and improving the versatility and ease of operation of the device.

[0040] In this embodiment, the digital creative drawing machine also includes a second positioning mechanism 7; there are two guide mechanisms 6, one of which corresponds to the first positioning mechanism 4 and the other corresponds to the second positioning mechanism 7, which are used to jointly guide the stability of the paper during transportation. The second positioning mechanism 7 includes a connecting shaft 701, a torsion spring 702, a side plate 703, a pressure roller 704, and an armrest 705. The connecting shaft 701 is fixedly connected to the housing 1, the side plate 703 is rotatably connected to the connecting shaft 701, the armrest 705 is fixedly connected to the side plate 703, and the pressure roller 704 is rotatably connected to the side plate 703 via a bearing. The torsion spring 702 is mounted on the connecting shaft 701, and the two ends of the torsion spring 702 are respectively fixedly connected to the side plate 703 and the connecting shaft 701.

[0041] The second positioning mechanism 7 is vertically aligned with the corresponding guide mechanism 6, forming an auxiliary path for paper transport. The guide mechanism 6 comprises a main shaft 601, which is rotatably connected to the housing 1, and multiple knurling patterns 602. The knurling patterns 602 are machined onto the main shaft 601 and correspond one-to-one with the pressure rollers 704. The pressure rollers 704 are preferably smooth rollers, rotatably connected to the side plates 703 via bearings to minimize frictional damage to the paper. The knurling patterns 602 are raised, textured structures that increase friction with the paper and, in conjunction with the pressure rollers 704, ensure smooth paper transport.

[0042] The connecting shaft 701 is preferably a metal shaft fixed to the housing 1, which serves to support and position the side panels 703. The side panels 703 are plate-like structures, preferably two symmetrically arranged plates, located at either end of the pressure roller 704. The connecting shaft 701 enables rotation relative to the housing 1. The torsion spring 702 provides an elastic reset force, allowing the pressure roller 704 to maintain close contact with the knurling 602 on the main shaft 601 of the guide mechanism 6 under normal conditions, thereby applying a stable pressing force to the paper. The armrest 705 is fixed to the outside of the side panel 703 to facilitate the operator to manually lift the side panel 703, thereby moving the pressure roller 704 away from the main shaft 601, facilitating the insertion or removal of paper.

[0043] In actual use, the operator pulls armrest 705, causing side plate 703 to rotate about connecting shaft 701, raising pressure roller 704. This overcomes the elastic force of torsion spring 702 and places the paper between pressure roller 704 and the corresponding main shaft 601 of guide mechanism 6. After releasing armrest 705, the return force of torsion spring 702 returns side plate 703 to its original position, pressing roller 704 firmly against knurling 602. The drive source (e.g., a motor) of guide mechanism 6 is activated, rotating main shaft 601 and driving the paper smoothly forward in a direction perpendicular to the movement of the refill on fixed component 3. Second positioning mechanism 7 cooperates with corresponding guide mechanism 6 to ensure that the paper does not deviate or wrinkle during transport, enhancing the device's drawing accuracy and paper transport stability.

[0044] In this embodiment, a reversing mechanism 5 is disposed within the housing 1 and is used to control the rotational direction of the two guide mechanisms 6, thereby enabling rapid switching between forward and reverse directions during paper transport. The reversing mechanism 5 includes two first motors 501, two first protrusions 502, a sleeve 503, an outer ring 504, two output shafts 505, two second protrusions 506, a slot 507, a gear 508, two racks 509, a slide bar 510, a spring 511, and an electric push rod 512.

[0045] Two first motors 501 are fixedly mounted within the housing 1. The motors 501 rotate in opposite directions, providing rotational power in opposite directions. Each first motor 501 has a first protrusion 502 on its output end. Two output shafts 505 are coaxially fixedly connected to the main shafts 601 of the two guide mechanisms 6, each with a second protrusion 506. The inner side of the sliding sleeve 503 is machined with a slot 507 matching the dimensions of the first and second protrusions 502, 506. The sliding sleeve 503 is slidably connected to the output ends of the first motors 501 and the outer wall of the output shaft 505, allowing for switching between the first and second protrusions 502, 506. An outer ring 504 is rotatably connected to the sliding sleeve 503 via a bearing and is slidably connected to two racks 509. The racks 509 mesh with a gear 508, which is rotatably connected to the housing 1 via a rotating shaft. Rotation of the gear 508 drives the racks 509 in opposite directions. An electric push rod 512 is fixed to the housing 1, with its output end connected to one of the racks 509, capable of driving the rack 509 to move along its length. A slide rod 510 has one end fixedly connected to the rack 509 and the other end slidably connected to the outer ring 504. A spring 511 is mounted on the slide rod 510, with its ends fixedly connected to the rack 509 and outer ring 504, respectively, to provide a reset force.

[0046] In this embodiment, the reversing mechanism 5 achieves rapid forward and reverse driving of the guide mechanism 6 through a clutch and transmission mechanism. The first motor 501 provides stable rotational power, and the two first motors 501 rotate in opposite directions to support rapid direction switching. The first and second protrusions 502, 506 are radially protruding key-like structures, preferably with a rectangular or trapezoidal cross-section to ensure reliable engagement with the retaining groove 507. The sleeve 503 is a hollow cylindrical structure, with the retaining groove 507 inside it serving as a matching groove for the first and second protrusions 502, 506, enabling selective engagement with either protrusion 502, 506 through axial sliding. The outer ring 504 is an annular structure, rotatably connected to the outer wall of the sleeve 503 via a bearing, ensuring that the outer ring 504 remains relatively stationary during the sleeve 503's rotation. Two racks 509 are linear racks, symmetrically arranged across the width of the housing 1, and slidingly engage with the guide grooves of the outer ring 504. Gear 508 is a circular gear fixed to the housing 1 via a rotating shaft. It meshes with two racks 509. Rotation of gear 508 causes the two racks 509 to move synchronously in opposite directions, thereby enabling rapid switching of power transmission direction. An electric push rod 512, driven by an electronic control system, precisely controls the movement of the racks 509. A slide rod 510 and spring 511 together form an elastic adjustment mechanism. Spring 511 provides a cushioning and restoring force during rack 509 movement, preventing impact on components caused by the rapid switching of the sleeve 503.

[0047] In actual use, the operator controls the electric push rod 512 to drive one of the racks 509 to move along its length direction, and the rack 509 drives the other rack 509 to move in the opposite direction through the gear 508. At the same time, each rack 509 drives the corresponding slide rod 510 and outer ring 504 to move, thereby pushing the corresponding sleeve 503 to slide axially, so that the slot 507 engages with the corresponding first protrusion 502 or maintains a sliding connection state with the second protrusion 506. When the slot 507 of one sleeve 503 engages with the corresponding first protrusion 502, power from the first motor 501 is directly transmitted to the corresponding output shaft 505, driving the corresponding spindle 601 in forward rotation and transporting the paper forward. When the slot 507 of the other sleeve 503 engages with the corresponding first protrusion 502, power from the first motor 501 is transmitted via the corresponding output shaft 505 to the other spindle 601 of the guide mechanism 6. Since the two first motors 501 rotate in opposite directions, the switching of power transmission paths causes the spindle 601 to rotate in the opposite direction, transporting the paper backward. The sleeve 503 remains in a sliding connection with the second protrusion 506, ensuring stability in the non-engaged state and smooth switching. A spring 511 ensures smooth movement of the sleeve 503 during switching, reducing mechanical vibration. The reversing mechanism 5 achieves rapid switching between paper forward and reverse movement through the opposite rotations of the two first motors 501, the gear 508 driving the two racks 509 in opposite directions, and the selective engagement of the sleeve 503 with the first protrusion 502. This mechanism meets complex drawing requirements and improves the device's automation and operational flexibility. When the slot 507 and the first protrusion 502 are not engaged, the spring 511 undergoes elastic deformation. When the slot 507 aligns with the first protrusion 502, the spring 511 loses its external support and elastically deforms, driving the slot 507 to engage with the first protrusion 502, thereby achieving transmission.
