Description

Technical Field

[0001] The present invention relates to the technical field of material handling, and in particular to a 3D printed part continuous conveying device. Background Art

[0002] In industrial production, in order to achieve automation and assembly line operation of 3D printing, 3D printed parts need to be quickly and stably transported from the printing area to subsequent processing, handling or packaging links to improve the efficiency and consistency of the entire production process.

[0003] In existing technology, 3D printers often require manual removal after printing, a slow, manual process. This process requires manual positioning, gripping, and other time-consuming actions. In large-scale production, the removal process can easily become a bottleneck in the entire production process, severely impacting production efficiency and leading to long wait times for subsequent processes, preventing a smooth production rhythm.

[0004] Even though existing technologies have developed automatic pickup mechanisms, the pickup process is still slow and fails to effectively solve the key issue of pickup speed. In contrast, it cannot meet the demand for fast pickup required for efficient production.

[0005] Therefore, a device is needed that has a fast pickup speed and can continuously transport 3D printed parts after printing. Summary of the Invention

[0018] Preferably, a driving motor is fixedly mounted on the fixed plate, and a shaft of the driving motor is fixedly connected to a driving wheel of the pulley assembly.

[0019] Preferably, a main pad and a secondary pad are fixedly provided on the printing platform, and an elastic sheet is provided in the secondary pad.

[0021] Preferably, a protective plate is fixedly provided on the base at a position on one side of the conveying component, and a plurality of adjustment foot pads are fixedly provided on the base.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This equipment adopts a rolling shutter type pickup method. The rolling shutter plate is driven by a pulley group to rotate, which can quickly remove the printed parts, greatly shortening the pickup time and improving the overall production efficiency.

[0024] 2. This equipment seamlessly integrates a 3D printer with a conveyor assembly, allowing multiple 3D printers to be connected to one conveyor assembly. Once a 3D printer completes printing, it automatically removes the part and delivers it to the next station, significantly reducing printer idle time and the wait time associated with manual disassembly.

Whether printing high-precision parts or products requiring high surface quality, this ensures the reliability of printed parts and reduces quality issues caused by gaps.

[0026] 4. By incorporating components such as a trigger lever, the shutter plate automatically lifts when the rolling shutter plate moves during removal, effectively reducing friction between the two. This not only reduces component wear, but also improves equipment stability, extends its service life, and reduces maintenance and component replacement costs.

[0027] 5. The guide plate can guide the printed parts into the conveying component area smoothly, reducing collision and friction. It can also shovel the printed parts off the roller shutter plate to assist in removing the parts, greatly improving the efficiency and success rate of removing the parts, and reducing the problems of printed parts damage or conveying delays caused by poor material removal.

[0028] 6. The elastic sheet resets and arches when removing the parts, which reduces the adhesion between the printed parts and the rolling plate, provides more powerful assistance for removing the parts, and further optimizes the removal process. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0043] See also Figure 1-12 , the present invention provides a technical solution:

[0044] Example 1:

[0045] like Figure 1 As shown, a 3D printed parts continuous conveying device, the basic supporting component of the device is a base 1, which provides a reliable bearing foundation for the entire device.

[0046] On the base 1, there are arranged a conveying assembly 2 and several 3D printers 3. The conveying assembly 2 is one of the key components to achieve continuous conveying of printed parts. It can take many forms, such as a belt conveyor, a stick conveyor or a chain conveyor.

[0047] This embodiment uses a belt conveyor as an example for detailed explanation. A belt conveyor consists of a transmission belt, a drive roller, a tensioning roller, and a bracket. The transmission belt wraps around the drive roller and tensioning roller. The drive roller is driven by a motor to rotate, thereby driving the transmission belt. The tensioning roller adjusts the belt tension to ensure stable operation. The bracket supports and secures the drive roller, tensioning roller, and transmission belt.

[0048] Several 3D printers 3 are arranged on one side of the conveyor assembly 2. Each 3D printer 3 has complete printing functionality, including a print head, an X-axis motion assembly, a Y-axis motion assembly, a Z-axis motion assembly, and a printing platform 402. In this embodiment, the focus is on the automatic material removal mechanism 4 installed on the Y-axis motion assembly of the 3D printer 3.

[0049] The ejection mechanism 4 primarily consists of a fixed plate 401, a printing platform 402, several pulley assemblies 403, several roller shutters 404, and a drive motor 9. Both the fixed plate 401 and the printing platform 402 are bolted to the Y-axis motion assembly of the 3D printer 3. The fixed plate 401 and the printing platform 402 are positioned parallel to each other at a predetermined distance to ensure the proper movement of subsequent components and to prevent any impact on the overall structural stability.

[0050] On fixed plate 401, several pulley groups 403 are installed by mounting bracket and fixture. Each pulley group 403 is made up of driving wheel, driven wheel and the belt connecting them.

[0051] The drive and driven pulleys are mounted on a mounting bracket via bearings, allowing for free rotation. The belts of these pulley assembly 403 are looped around the outside of the printing platform 402, forming a closed transmission system. This design allows the pulley assembly 403 to rotate, driving the belts along the outside of the printing platform 402.

[0052] Several rolling shutter plates 404 are fixed between the belts of the pulley assemblies 403, using adhesive or threaded connections. These rolling shutter plates 404 are typically made of a lightweight yet strong material, such as thin metal or high-strength plastic. The edges of the rolling shutter plates 404 are tightly connected to the belts, ensuring that they rotate synchronously with the belts as the pulley assemblies 403 rotate.

[0053] To drive the pulley assembly 403, a drive motor 9 is fixedly mounted on the fixed plate 401. Drive motor 9 utilizes a stepper motor, offering excellent power output and control accuracy. The shaft of drive motor 9 is fixedly connected to the drive pulley of pulley assembly 403 via a coupling or direct key connection. Thus, when drive motor 9 is activated, the rotation of the motor shaft is directly transmitted to the connected drive pulley, thereby driving the entire pulley assembly 403 system.

[0054] In this embodiment, several 3D printers 3 are arranged on one side of the conveyor assembly 2, and the Y-axis moving assembly of the 3D printer 3 is perpendicular to or at a certain angle to the transmission direction of the conveyor assembly 2. This layout design provides convenient conditions for the efficient transportation of printed parts.

[0055] When 3D printer 3 begins operation, the print head, under the coordinated control of the X-axis, Y-axis, and Z-axis motion components, deposits printing material layer by layer on the printing platform 402 along a preset printing path, completing the production of the printed part. When printing is complete, the control system of 3D printer 3 issues a command, and the Y-axis motion component begins to operate.

[0056] Driven by a motor, the Y-axis moving assembly moves the fixed plate 401, print platform 402, and the entire ejector mechanism 4 attached to it along the Y-axis, toward the conveyor assembly 2. During this process, the ejector mechanism 4 moves smoothly along with the Y-axis moving assembly until it reaches a pre-set position. This position is determined through precise calculation and debugging to ensure that the rolling plate 404 can accurately deliver printed parts to the conveyor assembly 2.

[0057] When the disengagement mechanism 4 reaches the designated position, the drive motor 9 is activated by the control system. The power generated by the drive motor 9 is transmitted through its shaft to the drive pulley of the connected pulley assembly 403, causing the drive pulley to begin rotating. Due to the belt connection, this rotation is quickly transmitted to the driven pulley in the same pulley assembly 403, and through the belt transmission, all other pulley assemblies 403 are driven to rotate synchronously. As the pulley assembly 403 rotates, the belt also begins to move in a circular motion, and the shutter plate 404 fixed to the belt also rotates accordingly.

[0058] At this time, the printed piece just printed is carried on the rolling plate 404. As the rolling plate 404 rotates, the printed piece gradually moves toward the direction of the conveying assembly 2. When the rolling plate 404 drives the printed piece to rotate to the position shown in FIG. Figure 6 In the position shown, due to the special structure and movement of the rolling shutter plate 404, the printed part gradually separates.

[0059] After the printed part is peeled off from the rolling shutter plate 404, it will naturally fall off from the 3D printer 3 and fall onto the transmission belt of the conveyor assembly 2. At this time, the drive roller of the conveyor assembly 2 continues to rotate under the drive of the motor, driving the transmission belt to move, thereby transporting the printed part along the conveying direction to the next station.

[0060] In actual production, one conveyor assembly 2 can be equipped with multiple 3D printers 3. After completing printing, each 3D printer 3 uses its own ejection mechanism 4 to transfer the workpiece to the conveyor assembly 2 according to the above process. The conveyor assembly 2 continuously transports these printed parts to subsequent processing or storage stations, achieving efficient and continuous transportation of 3D printed parts, greatly improving the automation and production efficiency of the entire 3D printing production process.

[0061] Example 2:

[0062] like Figure 2 As shown, in this embodiment, unlike the first embodiment, a plurality of 3D printers 3 are suspended above the conveying assembly 2 by means of support rods or the like. The Y-axis moving assembly of the 3D printer 3 has the same transmission direction as that of the conveying assembly 2. The 3D printers 3 are arranged at intervals. As long as the 3D printer 3 completes printing, the workpiece can be transferred to the conveying assembly 2 through the workpiece removal mechanism 4, and the conveying assembly 2 completes the continuous transportation of the workpiece.

[0063] Example 3:

[0064] On the basis of the above embodiment, this embodiment further optimizes the equipment and adds a pressure plate assembly 5, such as Figure 4-6 As shown, its main function is to ensure the stability of the rolling shutter plate 404 during the printing process and to avoid the quality of the printed product being affected by the gap between the rolling shutter plates 404.

[0065] Specifically, the pressing plate assembly 5 for pressing the rolling shutter plate 404 is arranged on the printing platform 402 .

[0066] The number of the pressure plate assemblies 5 is specifically set to two groups, which are respectively arranged at the two ends of the rolling shutter plate 404. Such a layout can apply uniform pressure to the rolling shutter plate 404 from both ends, and better ensure the stability of the rolling shutter plate 404 during the printing process.

[0067] A main pad 10 and a secondary pad 11 are fixedly mounted on the printing platform 402. The main pad 10 and the secondary pad 11 are made of material of the same thickness to ensure sufficient strength to support the rolling shutter plate 404. The thickness of the main pad 10 and the secondary pad 11 is greater than the thickness of the belt of the pulley assembly 403, a crucial design detail. When the pressure plate assembly 5 begins operating and applies pressure to the rolling shutter plate 404, the main pad 10 and the secondary pad 11 play a critical supporting role. They ensure that the rolling shutter plate 404 does not deform excessively due to the thickness limit of the belt when under pressure, thereby providing a stable support platform for the rolling shutter plate 404.

[0068] The platen assembly 5 includes pads 501 fixedly arranged on the printing platform 402. These pads 501 are fixed by bolts or the like and are firmly mounted on the printing platform 402 to ensure that they will not become loose or displaced during operation of the device.

[0069] A plurality of guide blocks 502 are fixedly mounted on the spacer 501. In this embodiment, there are three guide blocks 502. The guide blocks 502 are used to provide precise guidance for the guide post 503, ensuring that the guide post 503 maintains a stable trajectory during movement.

[0070] A guide post 503 slides within the guide block 502. To further enhance the smoothness and stability of the guide post 503's sliding motion, a guide sleeve can be positioned between the guide post 503 and the guide block 502, as needed. The guide sleeve is typically made of a wear-resistant material, such as copper alloy or high-performance engineering plastic. It effectively reduces friction between the guide post 503 and the guide block 502, minimizing wear and extending the life of the device.

[0071] A curtain pressure plate 6 is fixedly mounted on the guide column 503. The curtain pressure plate 6 is the component that directly contacts and applies pressure to the rolling shutter plate 404. Its shape and size are designed according to the specific specifications of the rolling shutter plate 404 to ensure that it can fully and evenly cover the rolling shutter plate 404 and apply effective pressure to it. In a specific design, the curtain pressure plate 6 may be provided with an upward-curved portion at both ends to prevent the rolling shutter plate 404 from being caught by the ends of the curtain pressure plate 6 when it moves.

[0072] In addition, a spring 7 is sleeved on the guide post 503. The spring 7 used in this embodiment is a compression spring, which is arranged between the curtain pressing plate 6 and the guide post 503, with one end of the compression spring being tightly connected to the curtain pressing plate 6 and the other end being fixed to a specific position on the guide post 503.

[0073] When the 3D printer 3 starts working, various small vibrations and external forces may be generated during the printing process, which may cause gaps to appear between the rolling shutter plates 404. During the operation of the device, the compression spring is always in a certain compression state, which will generate an upward elastic force.

[0074] This elastic force is evenly applied to the plurality of rolling shutter plates 404 through the shutter pressure plate 6, so that the rolling shutter plates 404 always maintain a tightly fitted state, thereby effectively preventing gaps from being generated between the rolling shutter plates 404 during printing.

[0075] This prevents the quality of printed parts from being affected by gaps between the rolling shutter plates 404. Whether printing high-precision parts or products with high surface quality requirements, the carefully designed platen assembly 5 can ensure the stability of the printing process and the reliability of the quality of the printed parts.

[0076] Example 4:

[0077] This embodiment provides another implementation of the pressure plate assembly 5 .

[0078] The pressure plate assembly 5 in this embodiment is mainly composed of a rotating seat 504, a rotating rod 505, a first crank 506, a curtain pressure plate 6 and a torsion spring.

[0079] like Figure 7-8 As shown, a rotating base 504 is provided on the printing platform 402, and the rotating base 504 provides a rotating support for a rotating rod 505. Bearings are installed at both ends of the rotating rod 505, and a first crank 506 is fixedly connected to one end of the rotating rod 505.

[0080] This connection method can be a key connection, by machining matching keyways on the rotating rod 505 and the first crank 506, and embedding the key therein, so as to achieve a close fit between the two and ensure the effective transmission of torque; or a pin connection can be used, by using the locating pin 8021 to accurately locate the position of the first crank 506 on the rotating rod 505 and transmit the rotational power of the rotating rod 505.

[0081] The first crank 506 is rotatably connected to the curtain pressing plate 6 via a pin. The pin ensures that the curtain pressing plate 6 can rotate flexibly relative to the first crank 506 within a certain range, and ensures that there will be no shaking or jamming during the rotation process, thereby achieving precise control of the movement of the curtain pressing plate 6.

[0082] The spring 7 is a power source for the pressure plate assembly 5, and its performance and installation method are crucial. The spring 7 in this embodiment is a torsion spring, which is sleeved on the rotating rod 505 and has two ends that are tightly connected to the rotating seat 504 and the first crank 506 respectively.

[0083] When the 3D printer 3 begins operating, the printing process inevitably generates various complex mechanical conditions, such as vibrations and impacts. These external forces can cause gaps to form between the rolling shutter plates 404, thereby affecting the quality of the printed product. In this situation, the torsional force of the torsion spring comes into play. Due to its stored elastic potential energy at its initial torsional angle, the torsion spring attempts to return to its initial state under the influence of external interference forces, generating a torque that drives the first crank 506 to rotate. This torque is transmitted to the pressure plate 6 via the pin between the first crank 506 and the pressure plate 6, causing it to gradually approach the rolling shutter plate 404 and apply pressure. As the torsion spring gradually recovers, the pressure of the pressure plate 6 on the rolling shutter plate 404 gradually increases, eventually closing the gap between the rolling shutter plates 404 and effectively preventing the gap from affecting the quality of the printed product.

[0084] In actual structural configuration, the number of rotating seats 504 can be reasonably selected between 2 and 4 groups based on specific equipment needs and printing process requirements. This flexible design fully considers the different requirements for the pressing effect of the rolling plate 404 in different printing tasks, as well as the limitations of the equipment space layout.

[0085] When positioning each set of rotating seats 504 and related components, particular attention must be paid to the extreme position of the first crank 506. When the curtain pressing plate 6 presses against the rolling shutter plate 404, the first crank 506 is in its extreme position, perpendicular to the curtain pressing plate 6. In this position, the pressure exerted by the curtain pressing plate 6 on the rolling shutter plate 404 reaches its maximum, and the reaction force exerted on the curtain pressing plate 6 coincides with the axis of the first crank 506. This position can be considered the dead center of the first crank 506.

[0086] At the dead center, the line of force applied coincides with the axis of the first crank 506, ensuring high stability. Even if the device experiences significant vibration or other external disturbances during printing, the forces acting on the pressure plate 6 are balanced by the reaction force aligning with the axis of the first crank 506, effectively preventing the pressure plate 6 from loosening during printing. This design, based on mechanical principles, further enhances the reliability and stability of the entire pressure plate assembly 5.

[0087] Embodiment 5:

[0088] In the process of in-depth research and optimization of the continuous conveying equipment for 3D printed parts, Example 5 is a further improvement based on Example 4.

[0089] The pressure plate assembly 5 of Example 4 plays an important role in ensuring that the rolling shutter plate 404 fits tightly and preventing gaps from occurring during printing. However, with the deepening of actual application, it is found that the pressure plate 6 always squeezes the rolling shutter plate 404. During the material removal process, the movement of the rolling shutter plate 404 will generate friction with the pressure plate 6. Long-term operation may cause wear of components and affect the stability and service life of the equipment.

[0090] To solve this problem, the fifth embodiment provides a series of components such as a trigger rod 802 , which aims to enable the curtain pressing plate 6 to be lifted when the rolling shutter plate 404 moves, thereby effectively reducing the adverse effects on the rolling shutter plate 404 .

[0091] The structure, connection relationship and working principle of the newly added components of Example 5 are described in detail below.

[0092] like Figure 9-11 As shown, several guide seats 801 are fixedly mounted on the fixed plate 401. A trigger rod 802 is slidably mounted within these guide seats 801. The trigger rod 802 is typically made of a high-strength, high-precision metal rod. Its diameter is precisely matched to the inner diameter of the guide seat 801, with tolerances kept within a very small range to ensure smooth axial sliding of the trigger rod 802 within the guide seat 801.

[0093] Several linkage rods 803 are vertically fixed to the trigger rod 802 via welding, keying, or other connection methods. This vertical arrangement ensures that the trigger rod 802 effectively transmits its axial motion to the linkage rods 803 during movement, achieving accurate motion conversion. The linkage rods 803 are made of similar materials and manufacturing processes as the trigger rod 802, exhibiting the same high strength and precision, ensuring that they will not deform or damage during motion transmission.

[0094] One end of the linkage rods 803 is rotatably mounted via a special pin, and at this rotational connection point, a connecting rod 804 is connected to the linkage rod 803, while the other end of the connecting rod 804 is rotatably connected to a second crank 805 fixed to the rotating rod 505. This connection constitutes a crank slider mechanism.

[0095] Specifically, when the trigger rod 802 is squeezed externally, Figure 11 As shown, axial sliding occurs within guide seat 801. Because trigger rod 802 and linkage rod 803 are vertically and fixedly connected, axial movement of trigger rod 802 inevitably drives synchronous movement of linkage rod 803. During movement, linkage rod 803, through its rotational connection with connecting rod 804, converts its own linear motion into oscillation of connecting rod 804, thereby driving second crank 805 to rotate about its rotation center.

[0096] It's important to emphasize that both the first crank 506 and the second crank 805 are precisely positioned and fixed on the same rotating rod 505. Furthermore, the axes of the first crank 506 and the second crank 805 are angled together. This design allows the second crank 805 to rotate synchronously with the first crank 506 through the rigid connection to the rotating rod 505. Furthermore, the first crank 506 is rotationally connected to the curtain pressure plate 6. Rotation of the first crank 506 lifts the curtain pressure plate 6, disengaging it from the rolling shutter plate 404 and reducing friction when the rolling shutter plate 404 moves.

[0097] To ensure accurate axial sliding of the trigger lever 802 when triggered without unnecessary rotation, several anti-rotation plates 806 are fixed to the printing platform 402 via bolts or other means. These plates are provided with anti-rotation grooves 8061, whose shape and dimensions precisely match the profile of the linkage lever 803, allowing the linkage lever 803 to slide smoothly within them. This design effectively limits the rotational freedom of the trigger lever 802 when triggered, ensuring that it can only slide axially along the guide base 801, thereby ensuring the accuracy and stability of the entire mechanism.

[0098] During actual operation, relying solely on the spring 7 on the rotating rod 505 to reset the trigger rod 802 may result in insufficient reset force or inaccurate reset. To address this issue, a positioning pin 8021 is fixedly provided on the trigger rod 802. The positioning pin 8021 serves to provide a precise positioning point for resetting the trigger rod 802. Furthermore, a spring 7 is sleeved on the trigger rod 802. This spring 7 is a compression spring, one end of which tightly abuts against the side wall of one of the guide seats 801, while the other end contacts the positioning pin 8021.

[0099] like Figure 10-11As shown, to enable the automatic triggering function of the trigger lever 802, a trigger block 807 is securely fixed to the frame of the 3D printer 3, using bolts or other means. The trigger block 807 matches the motion trajectory of the trigger lever 802. When the Y-axis moving assembly of the 3D printer 3 drives the printed part to remove the material, it simultaneously drives the trigger lever 802 toward the trigger block 807. As the Y-axis moving assembly moves, the trigger lever 802 gradually approaches the trigger block 807. When the trigger lever 802 contacts the trigger block 807, the blocking effect of the trigger block 807 causes the trigger lever 802 to move a certain amount. This displacement is ultimately transmitted to the first crank 506 and other components through the mechanical connection between the trigger lever 802, the linkage rod 803, the connecting rod 804, and the second crank 805. This causes the first crank 506 to rotate, which in turn drives the curtain pressing plate 6 to lift, thereby disengaging the curtain pressing plate 6 from the rolling curtain plate 404.

[0100] To reduce the impact force generated when trigger rod 802 contacts trigger block 807 and prevent damage to them, a cushion 8022 is fixed to one end of trigger rod 802 by gluing or other fixing methods. Cushion 8022 is typically made of a material with excellent elasticity and cushioning properties, such as rubber or polyurethane. When trigger rod 802 contacts trigger block 807, cushion 8022 effectively absorbs and cushions the impact force, extending the service life of trigger rod 802 and trigger block 807. It also reduces noise and vibration during device operation, improving the overall stability and reliability of the device.

[0101] Example 6:

[0102] This embodiment further improves the working efficiency and stability of the equipment by adding components such as the guide plate 13 and the protective plate 14, ensuring that the printed parts can be transported smoothly and safely.

[0103] picture Figure 6 and 9 As shown, a guide plate 13 is fixedly mounted on the fixed plate 401. The side of the guide plate 13 near the rolling plate 404 is chamfered. This serves to guide the printed workpiece more smoothly into the guide plate 13 during the stripping process, reducing collision and friction between the printed workpiece and the guide plate 13, thereby preventing damage to the printed workpiece. The chamfered design also helps to dissipate the impact force generated by the printed workpiece as it enters the guide plate 13, allowing the printed workpiece to smoothly transition onto the guide plate 13. Furthermore, the chamfered design also allows the printed workpiece to be scraped off the rolling plate 404.

[0104] The setting direction of the guide plate 13 follows the tangential direction of the guide wheel of the pulley group 403. Setting the guide plate 13 in this direction can match the motion path of the printed piece to the greatest extent, thereby achieving effective guidance of the printed piece.

[0105] When the rolling plate 404 is stripping the material, the entire process is an orderly and coordinated action. As the rolling plate 404 rotates, the printed part gradually moves toward the stripping position. When a portion of the printed part enters the area of ​​the guide plate 13, the guide plate 13 begins to play a role in assisting the stripping. During this process, the guide plate 13 cooperates with the rolling plate 404 and other components of the stripping mechanism 4 to act together on the printed part, allowing the printed part to be more smoothly separated from the rolling plate 404, improving the efficiency and success rate of stripping, and reducing problems such as damage to the printed part or transportation delays that may occur due to poor stripping.

[0106] A protective plate 14 is fixedly provided on the position of the base 1 on one side of the conveying assembly 2 by bolt connection or the like. The main function of the protective plate 14 is to prevent the printed piece from accidentally falling during the conveying process.

[0107] A number of adjustment pads 15 are also fixedly provided on the base 1. The function of the adjustment pads 15 is to fine-tune the levelness of the equipment to ensure that the equipment remains stable during operation. During the installation and use of the equipment, it may be affected by factors such as uneven ground and uneven distribution of the equipment's own weight, causing the equipment to tilt or shake. This will not only affect the conveying effect of the printed parts, but may also cause additional stress to the various components of the equipment, shortening the service life of the equipment. By adjusting the pads 15, the operator can rotate or adjust the height of the adjustment pads 15 according to actual conditions to make the equipment reach a horizontal state, thereby ensuring that the conveying component 2 can operate smoothly and the printed parts can be accurately conveyed to the designated position.

[0108] Embodiment seven:

[0109] In the fifth embodiment, the trigger lever 802 and other components are designed to enable the pressure plate 6 to lift when the rolling plate 404 moves, effectively reducing friction between the two. Furthermore, this embodiment provides a more powerful assist in the removal of the rolling plate 404 by providing an elastic sheet 12 in the auxiliary pad 11.

[0110] like Figure 12 As shown, the elastic sheet 12 in the auxiliary pad 11 is generally made of a metal material with good elasticity, such as beryllium bronze or specially treated spring steel. These materials can maintain stable elastic properties after repeated stress and deformation, ensuring long-term reliable operation.

[0111] When the pressure curtain plate 6 squeezes the rolling shutter plate 404, the entire system is in a normal printing process. At this time, the rolling shutter plate 404 is subjected to the pressure of the pressure curtain plate 6 and fits tightly together to ensure that no gaps appear during the printing process and to ensure the quality of the printed parts. In this process, due to the pressure transmission of the pressure curtain plate 6, the rolling shutter plate 404 will squeeze the elastic sheet 12 in the auxiliary pad 11. When squeezed, the elastic sheet 12 will undergo elastic deformation, its height will decrease, and it will be lower than the thickness of the auxiliary pad 11. It is ensured that in this state, the elastic sheet 12 will not interfere with the normal operation of the rolling shutter plate 404, and the pressure curtain plate 6, the rolling shutter plate 404 and other related components can continue to work together to successfully complete the printing task.

[0112] When printing is complete and the printer needs to remove the components, according to the design of the fifth embodiment, the trigger lever 802 and other components will function, causing the curtain pressing plate 6 to lift up and no longer press the curtain rolling plate 404. At this time, the elastic piece 12 in the auxiliary backing plate 11 returns to its original position. In the restored position, the elastic piece 12 presents an upwardly arched arc shape.

[0113] The arched elastic sheet 12 presses part of the rolling shutter plate 404 upward, causing part of the rolling shutter plate 404 to arch. This arched shape changes the contact between the rolling shutter plate 404 and the printed workpiece, effectively reducing the adhesion of the printed workpiece to the rolling shutter plate 404, thereby facilitating subsequent removal of the workpiece.

[0114] Working principle: During use of the present invention, the 3D printer 3 is turned on, and the print head, under the coordinated and precise control of the X-axis, Y-axis and Z-axis moving components, accumulates the printing material layer by layer on the printing platform 402 according to the preset printing path, gradually completing the production of the printed part.

[0115] After printing is completed, the control system of the 3D printer 3 issues a command, and the Y-axis moving assembly starts to move. The Y-axis moving assembly drives the relevant ejection mechanism 4 to move towards the conveying assembly 2 in preparation for ejection.

[0116] When the Y-axis moving assembly drives the printed part to be removed, trigger rod 802 approaches trigger block 807, causing displacement upon contact. This, through linkage rod 803 and connecting rod 804, rotates second crank 805, which in turn rotates first crank 506, lifting curtain pressing plate 6 and disengaging it from rolling curtain plate 404, thus reducing friction. A cushion 8022 at one end of trigger rod 802 absorbs the impact of contact with trigger block 807.

[0117] When the curtain pressing plate 6 is lifted, the elastic piece 12 is reset and arches upward in an arc shape, squeezing a portion of the rolling curtain plate 404 to make it arch, thereby reducing the adhesion between the printed part and the rolling curtain plate 404 and assisting in removing the part.

[0118] The drive motor 9 is then started, driving the pulley assembly 403 to rotate, thereby causing the rolling plate 404 fixed to the belt to rotate synchronously. The rolling plate 404 drives the printed piece to move toward the conveyor assembly 2. When it reaches a specific position, the printed piece is peeled off the rolling plate 404 and falls onto the belt of the conveyor assembly 2.

[0119] After the 3D printer 3 completes printing, it can automatically remove the parts and drop them onto the conveying component 2. The conveying component 2 continuously transports the printed parts to the next workstation, effectively avoiding the printer from being idle, reducing the waiting time for manual disassembly, and improving production efficiency.

[0120] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
