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 realize the 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 continuity of the entire production process.

[0003] In the existing technology, after the 3D printer finishes printing, it is often necessary to manually pick up the parts. This process relies on manual operation and is slow. Manual operations such as positioning and grabbing are required, which takes a long time. In large-scale production, the picking link can easily become a bottleneck in the entire production process, seriously affecting production efficiency, causing long waiting times for subsequent processes, and failing to form a smooth production rhythm.

[0004] Even though the existing technology has developed an automatic pickup mechanism, the pickup process is still slow and fails to effectively solve the key problem of pickup speed. In contrast, it cannot meet the demand for fast pickup for efficient production.

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

[0010] A plurality of rolling shutter plates are fixedly arranged between the belts of the plurality of pulley groups. When the pulley group rotates, the rolling shutter plates rotate synchronously. When the printed part on the rolling shutter plate rotates to the rotating wheel of the pulley group, the printed part is removed.

[0017] A trigger block is fixedly arranged on the frame of the 3D printer, and a buffer pad is fixedly arranged on one end of the trigger rod.

[0018] Preferably, a driving motor is fixedly arranged 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 arranged on the printing platform, and an elastic sheet is arranged in the secondary pad.

[0020] Preferably, a material guide plate is fixedly arranged on the fixed plate.

[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 adjusting 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 combines 3D printers with conveying components. One conveying component can be equipped with multiple 3D printers. Once the 3D printer completes printing, it can automatically remove the parts and convey them to the next station, greatly reducing the idle time of the printer and the waiting time for manual disassembly. Through this automated continuous conveying process, the efficiency of the entire 3D printing production process is significantly improved, effectively meeting the needs of large-scale production.

[0025] 3. The pressure plate assembly sets two sets of curtain pressure plates on the printing platform, applies uniform pressure from both ends of the rolling shutter plate, and cooperates with the support of the main pad and the auxiliary pad to effectively avoid gaps between the rolling shutter plates and ensure the stability of the printing process. Whether printing high-precision parts or products with high surface quality requirements, it can ensure the quality reliability of printed parts and reduce quality problems caused by gaps.

[0026] 4. By setting up components such as trigger rods, the shutter plate can be automatically lifted when the shutter plate moves during the picking process, effectively reducing the friction between the two. This not only reduces the wear of components, but also improves the stability of the equipment, extends the service life of the equipment, and reduces the cost of equipment maintenance and component replacement.

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

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

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 creative work are within the scope of protection of the present invention.

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

[0044] Embodiment 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, a conveying assembly 2 and a plurality of 3D printers 3 are arranged. The conveying assembly 2 is one of the key components for realizing continuous conveying of printed parts, and it can be in various forms, such as a belt conveyor, a stick conveyor or a chain conveyor.

[0047] In this embodiment, a belt conveyor is used as an example for detailed description. The belt conveyor is composed of a transmission belt, a driving roller, a tensioning roller, and a bracket. The transmission belt is wrapped around the driving roller and the tensioning roller. The driving roller is driven to rotate by a motor, thereby driving the transmission belt to move. The tensioning roller is used to adjust the tension of the belt to ensure that the belt can run stably. The bracket is used to support and fix the driving roller, the tensioning roller, and the transmission belt.

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

[0049] The stripping mechanism 4 is mainly composed of a fixing plate 401, a printing platform 402, a plurality of pulley groups 403, a plurality of rolling shutter plates 404 and a driving motor 9. The fixing plate 401 and the printing platform 402 are fixed to the Y-axis moving component of the 3D printer 3 by bolts. The fixing plate 401 and the printing platform 402 are arranged in parallel at a certain distance to ensure the normal movement of subsequent components and not affect the stability of the overall structure.

[0050] On the fixed plate 401, several pulley groups 403 are installed by mounting brackets and fixing devices. Each pulley group 403 is composed of a driving wheel, a driven wheel and the belt connecting them.

[0051] The driving wheel and the driven wheel are mounted on the mounting bracket through bearings and can rotate freely. The belts of the pulley set 403 are sleeved on the outside of the printing platform 402 to form a closed transmission system. This design enables the pulley set 403 to drive the belt to move along the outside of the printing platform 402 when rotating.

[0052] A plurality of rolling shutter plates 404 are fixedly arranged between the belts of the plurality of pulley sets 403 by means of adhesive or threaded connection. The material of these rolling shutter plates 404 is usually a thin material with a certain strength, such as a thin metal plate or a high-strength plastic plate. The edge of the rolling shutter plate 404 is tightly connected to the belt to ensure that when the pulley set 403 rotates, the rolling shutter plate 404 can rotate synchronously with the belt.

[0053] In order to drive the pulley group 403 to rotate, a driving motor 9 is also fixedly arranged on the fixed plate 401. The driving motor 9 adopts a stepping motor, which has good power output and control accuracy. The shaft of the driving motor 9 is fixedly connected to the driving wheel of the pulley group 403 by a coupling or a direct key connection. In this way, when the driving motor 9 is started, the rotation of the motor shaft can be directly transmitted to the driving wheel connected thereto, thereby driving the entire pulley group 403 system to rotate.

[0054] In this embodiment, a plurality of 3D printers 3 are arranged on one side of the conveying 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 conveying assembly 2. This layout design provides convenient conditions for efficient conveying of printed parts.

[0055] When the 3D printer 3 starts working, the print head, under the coordinated control of the X-axis, Y-axis and Z-axis moving components, deposits the printing material layer by layer on the printing platform 402 according to the preset printing path to complete the production of the printed part. When the printing is completed, the control system of the 3D printer 3 will issue a command, and the Y-axis moving component will start to move.

[0056] Driven by the motor, the Y-axis moving assembly drives the fixed plate 401, the printing platform 402 and the entire stripping mechanism 4 connected thereto along the Y-axis direction to move toward the conveying assembly 2. In this process, the stripping mechanism 4 moves smoothly along with the Y-axis moving assembly until it reaches the preset designated position. This designated position is determined through precise calculation and debugging to ensure that the rolling shutter plate 404 can accurately deliver the printed piece to the conveying assembly 2.

[0057] When the stripping mechanism 4 reaches the designated position, the drive motor 9 is started under the command of the control system. The power generated by the drive motor 9 is transmitted to the drive wheel of the belt pulley group 403 connected thereto through its shaft, and the drive wheel starts to rotate. Due to the connection of the belt, this rotation will be quickly transmitted to the driven wheel in the same belt pulley group 403, and through the transmission of the belt, all other belt pulley groups 403 will be driven to rotate synchronously. As the belt pulley group 403 rotates, the belt also starts to make a circular motion, and the rolling shutter plate 404 fixed on the belt also rotates accordingly.

[0058] At this time, the printed piece just printed is carried on the rolling shutter plate 404. As the rolling shutter plate 404 rotates, the printed piece gradually moves toward the direction of the conveying assembly 2. When the rolling shutter plate 404 drives the printed piece to rotate to the position shown in FIG. Figure 6 When 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 piece is peeled off from the rolling shutter plate 404, the printed piece will naturally fall off from the 3D printer 3 and fall onto the transmission belt of the conveying assembly 2. At this time, the driving roller of the conveying assembly 2 continues to rotate under the drive of the motor, driving the transmission belt to move, thereby transporting the printed piece to the next station along the conveying direction.

[0060] In the actual production process, one conveying assembly 2 can be equipped with multiple 3D printers 3. After each 3D printer 3 completes printing, it can transfer the workpiece to the conveying assembly 2 using its own workpiece removal mechanism 4 according to the above process. The conveying assembly 2 will continuously transport these printed parts to subsequent processing or storage stations, realizing efficient and continuous conveyance of 3D printed parts, greatly improving the automation and production efficiency of the entire 3D printing production process.

[0061] Embodiment 2:

[0062] like Figure 2 As shown, in this embodiment, different from 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 the conveying assembly 2, and 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 stripping mechanism 4, and the conveying assembly 2 completes the continuous transportation of the workpiece.

[0063] Embodiment three:

[0064] On the basis of the above embodiment, the present embodiment further optimizes the equipment by adding a pressure plate assembly 5. 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 affecting the quality of the printed product due to the gap between the rolling shutter plates 404.

[0065] Specifically, a pressure 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] The main pad 10 and the auxiliary pad 11 are fixedly arranged on the printing platform 402. The main pad 10 and the auxiliary pad 11 are made of materials of the same thickness to ensure sufficient strength to support the rolling shutter plate 404. The thickness of the main pad 10 and the auxiliary pad 11 is greater than the thickness of the belt of the pulley assembly 403. This design detail is crucial. When the pressure plate assembly 5 starts working and applies pressure to the rolling shutter plate 404, the main pad 10 and the auxiliary pad 11 will play a key supporting role. They can ensure that the rolling shutter plate 404 will not be excessively deformed due to the thickness limit of the belt when it is 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 fixedly mounted on the printing platform 402 by bolt connection or the like, ensuring that they will not loosen or move during the operation of the equipment.

[0069] A plurality of guide blocks 502 are fixedly arranged on the cushion block 501. In this embodiment, the number of the guide blocks 502 is set to three. The function of these guide blocks 502 is to provide accurate guidance for the guide column 503, ensuring that the guide column 503 can maintain a stable trajectory during the movement.

[0070] A guide post 503 is slidably arranged in the guide block 502. In order to further improve the smoothness and stability of the sliding of the guide post 503, a guide sleeve can be arranged between the guide post 503 and the guide block 502 according to actual needs. The guide sleeve is usually made of wear-resistant materials, such as copper alloy or high-performance engineering plastics, which can effectively reduce the friction between the guide post 503 and the guide block 502, reduce the degree of wear, and extend the service life of the equipment.

[0071] A curtain pressing plate 6 is fixedly arranged on the guide column 503. The curtain pressing plate 6 is a component that directly contacts and applies pressure to the rolling curtain plate 404. Its shape and size are designed according to the specific specifications of the rolling curtain plate 404 to ensure that it can fully and evenly cover the rolling curtain plate 404 and apply effective pressure to it. In the specific design, both ends of the curtain pressing plate 6 can be provided with upwardly tilted parts, so as to prevent the rolling curtain plate 404 from being caught by the two ends of the curtain pressing plate 6 when it moves.

[0072] In addition, a spring 7 is sleeved on the guide column 503. The spring 7 used in this embodiment is a compression spring, which is arranged between the curtain pressing plate 6 and the guide column 503, one end of which is closely connected to the curtain pressing plate 6, and the other end is fixed to a specific position on the guide column 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 between the rolling shutter plates 404. During the operation of the device, the compression spring is always in a certain compression state, and it will generate an upward elastic force.

[0074] This elastic force is evenly applied to the plurality of rolling shutter plates 404 through the curtain 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] In this way, the quality of the printed product is prevented from being affected by the gap between the rolling shutter plates 404. Whether printing high-precision parts or products with high surface quality requirements, the carefully designed pressure plate assembly 5 can ensure the stability of the printing process and the quality reliability of the printed product.

[0076] Embodiment 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 seat 504 is provided on the printing platform 402, and the rotating seat 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 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 connected to the curtain pressing plate 6 by 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 the power source of the pressure plate assembly 5, and its performance and installation method are very important. The spring 7 in this embodiment is a torsion spring, which is sleeved on the rotating rod 505, and its two ends are closely connected to the rotating seat 504 and the first crank 506 respectively.

[0083] When the 3D printer 3 starts working, various complex mechanical environments, such as vibration, impact force, etc., will inevitably be generated during the printing process. These external forces may cause gaps between the rolling shutter plates 404, thereby affecting the quality of the printed product. In this case, the torsion force of the torsion spring begins to play a role. Due to the initial torsion angle, the torsion spring stores elastic potential energy. Under the action of external interference force, it tries to return to the initial state, thereby generating a torque that drives the first crank 506 to rotate. This torque is transmitted to the pressing curtain plate 6 through the pin between the first crank 506 and the pressing curtain plate 6, so that the pressing curtain plate 6 gradually approaches the rolling shutter plate 404 and applies pressure. As the torsion spring gradually recovers, the pressure of the pressing curtain plate 6 on the rolling shutter plate 404 gradually increases, and finally the gap between the rolling shutter plates 404 is tightly closed, effectively preventing the gap from affecting the quality of the printed product.

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

[0085] For the position setting of each set of rotating seats 504 and related components, special attention should be paid to the extreme position of the first crank 506. When the curtain pressing plate 6 presses the rolling curtain plate 404, the first crank 506 is at the extreme position, and the first crank 506 is perpendicular to the curtain pressing plate 6. At this position, the pressure applied by the curtain pressing plate 6 to the rolling curtain plate 404 reaches the maximum, and the reaction force received by the curtain pressing plate 6 coincides with the axis position of the first crank 506. It can be understood that this position is the dead point position of the first crank 506.

[0086] At the dead point, the line of action of the force coincides with the axis of the first crank 506, so that the first crank 506 has extremely high stability at this position. Even if the device is subjected to a large vibration or other external force interference during the printing process, the external force on the pressure curtain plate 6 will be balanced by the reaction force that coincides with the axis of the first crank 506, thereby effectively preventing the pressure curtain plate 6 from loosening during printing. This design based on the principle of mechanics further improves the reliability and stability of the entire pressure plate assembly 5.

[0087] Embodiment five:

[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 practical applications, it is found that the pressure curtain plate 6 always squeezes the rolling shutter plate 404. During the material stripping process, the movement of the rolling shutter plate 404 will generate friction with the pressure curtain 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 curtain plate 404 moves, thereby effectively reducing the adverse effects on the rolling curtain 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, a plurality of guide seats 801 are fixedly arranged on the fixed plate 401. A trigger rod 802 is slidably arranged in these guide seats 801. The trigger rod 802 is usually made of a high-strength, high-precision metal rod, and its diameter is precisely matched with the inner diameter of the guide seat 801, and the tolerance is controlled within a very small range to ensure that the trigger rod 802 can smoothly slide axially in the guide seat 801.

[0093] A plurality of linkage rods 803 are vertically fixedly arranged on the trigger rod 802 by welding, key connection or other connection methods. This vertical arrangement ensures that the trigger rod 802 can effectively transmit its own axial movement to the linkage rod 803 when it moves, so as to achieve accurate conversion of movement. The material and manufacturing process of the linkage rod 803 are similar to those of the trigger rod 802, and also have the characteristics of high strength and high precision to ensure that there will be no deformation or damage during the transmission of movement.

[0094] One end of the plurality of linkage rods 803 is rotatably arranged through a special pin shaft, and at this rotation connection point, the connecting rod 804 is connected to the linkage rod 803, and the other end of the connecting rod 804 is rotatably connected to the second crank 805 fixedly arranged on the rotating rod 505. This connection method constitutes a crank slider mechanism.

[0095] Specifically, when the trigger rod 802 is pressed externally, Fig.11 As shown, axial sliding will occur in the guide seat 801. Since the trigger rod 802 and the linkage rod 803 are vertically and fixedly connected, the axial movement of the trigger rod 802 will inevitably drive the linkage rod 803 to move synchronously. During the movement, the linkage rod 803 converts its own linear motion into the swing of the linkage rod 804 through the rotation connection with the connecting rod 804, thereby driving the second crank 805 to rotate around its rotation center.

[0096] It should be emphasized that the first crank 506 and the second crank 805 are both mounted on the same rotating rod 505 by precise positioning and fixing. There is a certain angle between the axes of the first crank 506 and the second crank 805. This design enables the second crank 805 to drive the first crank 506 to rotate synchronously through the rigid connection of the rotating rod 505 when rotating. There is a rotational connection between the first crank 506 and the curtain pressing plate 6. When the first crank 506 rotates, it drives the curtain pressing plate 6 to lift up, thereby realizing the action of disengaging the curtain pressing plate 6 from the rolling curtain plate 404, thereby achieving the purpose of reducing friction when the rolling curtain plate 404 moves.

[0097] In order to ensure that the trigger rod 802 can accurately slide axially when it is triggered without unnecessary rotation, a plurality of anti-rotation plates 806 are fixedly provided on the printing platform 402 by bolt connection or the like. An anti-rotation slide groove 8061 is provided on the anti-rotation plate 806, and the shape and size of the anti-rotation slide groove 8061 are precisely matched with the shape of the linkage rod 803, so that the linkage rod 803 can slide smoothly in the anti-rotation slide groove 8061. This design effectively limits the rotational freedom of the trigger rod 802 when it is triggered, and ensures that the trigger rod 802 can only slide along the axial direction of the guide seat 801, thereby ensuring the movement accuracy and stability of the entire mechanism.

[0098] In actual operation, if the trigger rod 802 is reset only by the spring 7 on the rotating rod 505, there may be a problem of insufficient reset force or inaccurate reset. To solve this problem, a positioning pin 8021 is fixedly provided on the trigger rod 802. The function of the positioning pin 8021 is to provide an accurate positioning point for the reset of the trigger rod 802. At the same time, a spring 7 is sleeved on the trigger rod 802, and the spring 7 is a compression spring, one end of which is tightly against the side wall of one of the guide seats 801, and the other end is in contact with the positioning pin 8021.

[0099] like Figure 10-11As shown, in order to realize the automatic triggering function of the trigger rod 802, a trigger block 807 is firmly fixed on the frame of the 3D printer 3 by bolt fixing or the like. The trigger block 807 matches the motion trajectory of the trigger rod 802. When the Y-axis moving component of the 3D printer 3 drives the printed part to perform the material stripping operation, it will simultaneously drive the trigger rod 802 to move in the direction close to the trigger block 807. As the Y-axis moving component moves, the trigger rod 802 gradually approaches the trigger block 807. When the trigger rod 802 contacts the trigger block 807, due to the blocking effect of the trigger block 807, the trigger rod 802 will produce a certain displacement. This displacement will be transmitted to the first crank 506 and other components through the mechanical connection between the trigger rod 802 and the linkage rod 803, the connecting rod 804 and the second crank 805, so that the first crank 506 rotates, thereby driving the pressure curtain plate 6 to lift, and realizing the disengagement of the pressure curtain plate 6 from the rolling curtain plate 404.

[0100] In order to reduce the impact force generated when the trigger rod 802 contacts the trigger block 807 and avoid damage to the trigger rod 802 and the trigger block 807, a buffer pad 8022 is fixedly provided at one end of the trigger rod 802 by gluing or other fixing methods. The buffer pad 8022 is usually made of a material with good elasticity and buffering performance, such as rubber or polyurethane. When the trigger rod 802 contacts the trigger block 807, the buffer pad 8022 can effectively absorb and buffer the impact force, extend the service life of the trigger rod 802 and the trigger block 807, and also reduce the noise and vibration during the operation of the device, thereby improving the overall stability and reliability of the device.

[0101] Embodiment six:

[0102] This embodiment further improves the working efficiency and stability of the device by adding components such as the guide plate 13 and the protection 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 arranged on the fixed plate 401. The side of the guide plate 13 close to the rolling shutter plate 404 is designed to be chamfered. Its function is to guide the printed piece to enter the guide plate 13 area more smoothly during the material stripping process, reduce the collision and friction between the printed piece and the guide plate 13, and avoid damage to the printed piece. At the same time, the chamfer design also helps to disperse the impact force generated by the printed piece when entering the guide plate 13, so that the printed piece can smoothly transition to the guide plate 13. At the same time, the guide plate 13 can also shovel the printed piece from the rolling shutter plate 404 through the chamfer.

[0104] The setting direction of the guide plate 13 follows the tangent direction of the guide wheel of the pulley group 403. The guide plate 13 is set in this direction, which can be matched with the movement path of the print piece to the greatest extent, and the print piece can be effectively guided.

[0105] When the rolling shutter plate 404 is stripping the material, the whole process is an orderly and coordinated action. As the rolling shutter plate 404 rotates, the printed piece gradually moves to the stripping position. When a part of the printed piece enters the area of ​​the guide plate 13, the guide plate 13 begins to play an auxiliary stripping role. In this process, the guide plate 13 cooperates with the rolling shutter plate 404 and other components of the stripping mechanism 4 to act on the printed piece, so that the printed piece can be more smoothly detached from the rolling shutter plate 404, thereby improving the efficiency and success rate of stripping and reducing problems such as damage to the printed piece or delay in transportation caused by poor stripping.

[0106] A protective plate 14 is fixedly provided at a 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, the equipment may be affected by factors such as uneven ground and uneven weight distribution of the equipment itself, causing the equipment to tilt or shake, which will not only affect the conveying effect of the printed matter, but may also cause additional stress to various components of the equipment and shorten 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 the actual situation to make the equipment reach a horizontal state, thereby ensuring that the conveying component 2 can run smoothly and the printed matter can be accurately conveyed to the specified position.

[0108] Embodiment seven:

[0109] Embodiment 5 realizes lifting of the curtain pressing plate 6 when the curtain rolling plate 404 moves by designing components such as the trigger rod 802, effectively reducing the friction between the two. On this basis, this embodiment provides a more powerful assistance for the curtain rolling plate 404 to be released by setting an elastic sheet 12 in the auxiliary pad 11.

[0110] like Fig.12 As shown, the elastic sheet 12 in the auxiliary pad 11. The elastic sheet 12 is usually made of metal materials with good elasticity, such as beryllium bronze or specially treated spring steel, etc. 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 tightly fitted together by the pressure of the pressure curtain plate 6 to ensure that no gaps will 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, and its height will decrease and 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 completed and the stripping operation is required, according to the design of the fifth embodiment, the trigger lever 802 and other components will play a role, so that the curtain pressing plate 6 is lifted and no longer presses the rolling curtain plate 404. At this time, the elastic sheet 12 in the auxiliary pad 11 is reset. In the reset state, the elastic sheet 12 presents an arc-shaped upward arched shape.

[0113] The arched elastic sheet 12 will press part of the rolling shutter plate 404 upward, so that part of the rolling shutter plate 404 will also arch. This arched shape changes the contact state between the rolling shutter plate 404 and the printed work, effectively reducing the adhesion of the printed work to the rolling shutter plate 404, thereby facilitating the subsequent removal of the work.

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

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

[0116] When the Y-axis moving assembly drives the printed part to be removed, the trigger rod 802 approaches the trigger block 807, and displacement occurs after contact, and the second crank 805 is rotated through the linkage rod 803 and the connecting rod 804, thereby driving the first crank 506 to rotate, so that the pressing curtain plate 6 is lifted and separated from the rolling curtain plate 404 to reduce friction. The buffer pad 8022 at one end of the trigger rod 802 can absorb the impact force when contacting the trigger block 807.

[0117] When the curtain pressing plate 6 is lifted, the elastic sheet 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 printed part.

[0118] Then the driving motor 9 starts, driving the pulley set 403 to rotate, thereby causing the rolling plate 404 fixed on the belt to rotate synchronously. The rolling plate 404 drives the printed piece to move toward the conveying 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 conveying assembly 2.

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

[0120] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
