Description
Technical Field
[0001] This invention relates to the field of printing and molding apparatus technology, specifically a printing and molding apparatus for processing plastic sheets. Background Technology
[0002] As is well known, additive manufacturing technology is an advanced manufacturing technology that builds three-dimensional entities by stacking materials layer by layer based on digital models. Its principle is to divide the designed three-dimensional model into a series of two-dimensional thin slices using slicing software, and then the 3D printer adds materials layer by layer according to the contour information of these thin slices and solidifies them to finally form a complete three-dimensional object. A printing and molding device for processing plastic sheets is a 3D printing and molding device that assists in the processing of plastic sheets.
[0003] A search revealed two patents: Chinese Patent Publication No. CN105835372A and Chinese Patent Publication No. CN105643936A, which disclose a 3D printer and a full-color 3D printer, respectively. The former is roughly described as including a mounting frame, an extrusion device, a shifting device, a material output device, and a processing platform. The material output device includes a wire output mounting base, an upper wire output pipe, a lower wire output pipe, a wire output motor, a wire output drive wheel, and a wire output auxiliary wheel. The outer circumferential surfaces of the wire output drive wheel and the wire output auxiliary wheel form a wire transmission cavity. The lead-out auxiliary wheel rotates in conjunction with the lead-out mounting base. The lead-out motor drives the lead-out drive wheel to rotate. The upper and lower lead-out pipes, through which the printing material passes, are arranged vertically on the lead-out mounting base. A transmission interval is provided between the upper and lower lead-out pipes, corresponding to the position of the transmission cavity. A swing arm is provided on the lead-out mounting base, and an adjusting bolt is provided on the swing arm along the swing direction. The adjusting bolt is equipped with a limiting adjusting nut and a limiting retaining ring, the latter of which is roughly described as including a support platform, an X-axis guide rail, and a Y-axis... The system comprises a guide rail, Z-axis guide rail, printing platform, lifting platform, drive screw, print head, photopolymerization device, support plate, first material tank, second material tank, third material tank, fourth material tank, feeding conduit, UV lamp, light intensity adjustment device, several micro-printers, several longitudinal baffles, and transverse baffles. In operation, a computer designs a 3D solid model of the object to be printed. The computer slices the 3D solid model into layers along the internal direction corresponding to the actual vertical direction, obtaining the molding data for each layer. The computer controls the movement of the print head, spraying photosensitive resin liquid into the area corresponding to the printing platform. Under UV light irradiation, the resin solidifies, forming the bottom layer of the 3D solid object on the printing surface. The print head moves upwards, printing layer by layer until the final 3D solid object is printed. Each micro-printer corresponds to a different color of photosensitive resin liquid. Different colors can be changed according to printing needs, and two different colors can be mixed to create more colors to meet user requirements, thus achieving full-color 3D printing.
[0004] While both of the aforementioned existing technical solutions can achieve additive manufacturing, the worktable formed by the additive manufacturing process is more suitable for printing general-purpose parts, i.e. parts with a coordinated length, width, and height ratio. However, in actual design processes, there is a type of plastic sheet part with a larger area. Since the length and width of this type of part are relatively large and the height is relatively small, the printing size and work efficiency will be limited if traditional general-purpose additive manufacturing equipment is used, and the equipment utilization rate will also be low. Its practicality needs to be further improved. Summary of the Invention

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0040] Example
[0041] Please see Figures 1-16A printing and molding device for processing plastic sheets includes a processing platform and a main body. The main body includes a main shell 1, a vertical material bin 2 inside the main shell 1, a protrusion 3 at the rear end of the main shell 1, a first servo motor 4 mounted at the top of the protrusion 3, a vertical guide groove 5 communicating with the vertical material bin 2 inside the protrusion 3, a lifting frame 6 slidably connected inside the vertical guide groove 5, the height of the lifting frame 6 being adjusted and controlled by the first servo motor 4, a lifting clamping assembly mounted at the front end of the lifting frame 6, and a base sheet 7 detachably mounted inside the lifting clamping assembly. Through the design of the main body, the matching lifting clamping assembly and processing platform form a corresponding main body installation structure, providing basic conditions for the printing and processing of plastic sheets. The lifting clamping assembly includes a lifting shell 12, which is fixedly connected to the lifting frame 6, and a drive frame 13 rotatably connected inside the lifting shell 12. A second servo motor 14 is installed at the top, which drives the rotation of the drive frame 13. A pick-and-place shell 15 is detachably installed inside the lifting shell 12. A cooperating pressure frame 16 is rotatably connected inside the pick-and-place shell 15. The base sheet 7 is installed between the drive frame 13 and the cooperating pressure frame 16. Two insertion posts 17 are fixedly connected to the cooperating pressure frame 16. An auxiliary pressure ring 18 is slidably connected to the two insertion posts 17. Multiple elastic springs 19 are fixedly connected between the auxiliary pressure ring 18 and the cooperating pressure frame 16. Two preset holes 20 matching the insertion posts 17 are opened on the base sheet 7. Two insertion slots 21 are opened on the drive frame 13. The two insertion slots 21 are respectively matched with the two insertion posts 17. With the lifting clamping assembly, it is convenient to form a lifting, adjustable and rotating drive structure for the plastic sheet to be processed, which facilitates the necessary motion drive for the printing operation of the plastic sheet to be printed.
[0042] It should be further explained that two mating rods 22 are slidably connected inside the take-up and put-down housing 15. Both mating rods 22 are slidably connected to the take-up and put-down housing 15. Two matching slots 23 are opened inside the lifting housing 12. The two mating rods 22 are respectively matched with the two matching slots 23. A toggle bar 24 is fixedly connected to one of the mating rods 22. An extension bar opening 25 is opened on the take-up and put-down housing 15. The toggle bar 24 is slidably connected in the extension bar opening 25. One of the mating rods 22 is fixedly connected to the lifting housing 15. A return spring 26 is fixedly connected to the two insertion rods 22. The return spring 26 is fixedly connected inside the insertion shell 15. A linkage component is provided between the two insertion rods 22. The linkage component includes a synchronous gear 27 and two synchronous racks 28. The synchronous gear 27 is rotatably connected inside the insertion shell 15. The two synchronous racks 28 are fixedly connected to the two insertion rods 22 respectively. A protective cover 29 is provided outside the synchronous gear 27. The protective cover 29 is fixedly connected inside the insertion shell 15 to facilitate the installation, positioning and disassembly of the insertion shell 15 relative to the lifting shell 12. Multiple guide rails 30 are fixedly connected inside the insertion shell 15. Multiple guide rail sleeves 31 are fixedly connected inside the lifting shell 12. The multiple guide rails 30 are matched with the multiple guide rail sleeves 31 respectively. The front end of each of the multiple guide rail sleeves 31 is provided with a guide opening 32. When the insertion shell 15 is inserted into the lifting shell 12, the alignment and insertion between the insertion shell 15 and the lifting shell 12 can be achieved by inserting the multiple guide rails 30 into the multiple guide rails 30 respectively. A front horizontal support frame 33 is fixedly connected inside the hopper 2. Two rear horizontal support slots 34 are provided inside the vertical hopper 2. The front ends of the two support frames 8 are fixedly connected to front slides 35, and the rear ends of the two support frames 8 are fixedly connected to rear slides 36. The two front slides 35 are slidably connected inside the front horizontal support frame 33. The two rear slides 36 are slidably connected inside the two rear horizontal support slots 34 respectively. The two rear slides 36 are fixedly connected to external push springs 37 respectively. The two external push springs 37 are fixedly connected inside the two rear horizontal support slots 34 respectively.
[0043] Furthermore, the processing platform includes two support frames 8, both installed inside the vertical material bin 2. Synchronizing cylinders 9 are rotatably connected to the outside of each support frame 8. Release rings 10 are detachably installed on the outside of each synchronous cylinder 9. The installation of the release rings 10 relative to the synchronous cylinders 9 is assisted by auxiliary pressure rings at both ends. Specifically, the release rings 10 are first fitted onto the synchronous cylinders 9, and then the auxiliary pressure rings are fitted onto the stepped ends of the synchronous cylinders 9. Finally, bolts are used to secure the auxiliary pressure rings to the synchronous cylinders 9. Each synchronous cylinder 9 is equipped with a light-curing lamp 11. The two light-curing lamps 11 are respectively installed... Within the two support frames 8, two light-curing lamps 11 can respectively illuminate the two release film rings 10 through the two synchronization cylinders 9. A synchronization structure is provided between the two synchronization cylinders 9 and the base sheet 7. Through the design of the processing platform, functional components for curing and molding the plastic sheet are provided, and the multi-point curing method is adopted to further improve the curing efficiency. The synchronization structure includes a synchronization belt 38, which is driven by a drive wheel 39, two fixed wheels 40, and two follower wheels 41. The drive wheel 39 is fixedly connected to the drive frame 13, and the two fixed wheels 40 are rotatably connected to the vertical hopper 2. The moving wheel 41 is fixedly connected to two synchronous cylinders 9 respectively. Both front slides 35 are fixedly connected to an extension tube 42. Each extension tube 42 contains a wire 43, which supplies power to the two UV curing lamps 11 respectively. The front end of the take-up and put-down housing 15 has a recessed inlet 44 that matches the extension tube 42. Through the synchronous structure design, the base sheet 7 and the synchronous cylinders 9 rotate synchronously. Simultaneously, when the base sheet 7 rises or falls, the distance between the two synchronous cylinders 9 can be adjusted accordingly, facilitating appropriate printing distances between the two UV curing lamps 11 and plastic sheets of different sizes. A vertical lead screw 45 and a vertical rotating shaft 46 are rotatably connected to the output shaft of the first servo motor 4 and the output shaft of the second servo motor 14, respectively. A drive sleeve 47 is threaded onto the vertical lead screw 45 and is fixedly connected inside the lifting frame 6. A drive bevel gear 48 is fixedly connected to the bottom end of the vertical rotating shaft 46. The drive bevel gear 48 meshes with a transmission bevel gear 49 and is fixedly connected to the drive frame 13. This provides a specific technical solution for the drive function between the first servo motor 4 and the lifting frame 6, and also provides a specific technical solution for the transmission function between the second servo motor 14 and the drive frame 13.
[0044] In this embodiment, the light curing lamp 11, the first servo motor 4, and the second servo motor 14 are all commercially available conventional devices known to those skilled in the art. In this invention, we are simply using them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.
[0045] In summary, the working principle of the printing and molding device for processing plastic sheets is as follows: First, the device is installed at the designated location. During installation, the main body shell 1 is fixed using the flange surrounding its bottom. After positioning, the first servo motor 4, the second servo motor 14, and the two photocuring lamps 11 are electrically installed. During installation, the controller should be tested and adjusted. The controller enables the operation control of the first servo motor 4, the second servo motor 14, and the two photocuring lamps 11. A base sheet 7 is pre-fabricated, which can be achieved using a general-purpose 3D printer. Then, the first servo motor 4 is powered on. Powering on the first servo motor 4 drives the rotation of the vertical lead screw 45. Under the transmission of the drive sleeve 47, the rotation of the vertical lead screw 45 adjusts the height of the lifting frame 6. Controlling the lifting frame 6 to raise it allows the shell 15 to be completely extracted relative to the main body shell 1. By moving the toggle bar 24, the two insertion rods are engaged. The two insertion rods 22 are pulled away from the two slots 23 respectively, and the two insertion rods 22 are pulled away from the two slots 23 respectively. The pick-and-place shell 15 is pulled out from the lifting frame 6. Then, the pre-prepared base sheet 7 is placed on the insertion post 17, so that the two insertion posts 17 are inserted into the two preset holes 20 respectively. Then, the pick-and-place shell 15 is inserted into the lifting frame 6 again, so that the base sheet 7 and the drive frame 13 are in close contact, and the insertion post 17 is controlled to be inserted into the two insertion slots 21. When the pick-and-place shell 15 is installed in place relative to the lifting frame 6, the two insertion rods 22 will be inserted into the two slots 23 respectively, so as to realize the repositioning of the pick-and-place shell 15 in the lifting frame 12. After the positioning is completed, the elastic spring 19 will be compressed, and the auxiliary pressure ring 18 will slide relative to the insertion post 17. On the one hand, it can adapt to the thickness of the base sheet 7 and adjust it accordingly. On the other hand, it can also further compress the base sheet 7 in preparation for subsequent printing operations.
[0046] Further, printing liquid material is added to the vertical material bin 2, and then the first servo motor 4 is powered on to lower the height of the lifting shell 12, so that the lifting shell 12 and the pick-and-place shell 15 are inserted into the vertical material slot as a whole. Since the height of the lifting shell 12 is lowered, the drive wheel 39 is lowered synchronously. The height of the drive wheel 39 is lowered, which can further press the synchronous belt 38. Therefore, the two corresponding follower wheels 41 will be closer to each other, so that the release film ring 10 can be close to the smaller base sheet 7 in the early stage of printing. After both release film rings 10 are in contact with the base sheet 7, the first servo motor 4 enters the parking state to maintain the relative height of the lifting shell 12. Then the second servo motor 14 is powered on to drive the rotation of the vertical shaft 46, which drives the bevel gear 48 and the transmission. Under the meshing transmission action between the bevel gears 49, the rotation of the vertical shaft 46 can realize the rotation drive of the drive frame 13. The rotation of the drive frame 13 can realize the rotation of the base sheet 7 that is in contact with and pressed against it. At the same time, the rotation of the drive frame 13 will also drive the drive wheel 39 to rotate. The rotation of the drive wheel 39 realizes the synchronous rotation drive of the two synchronous cylinders 9 through the synchronous belt 38. The rotation of the two synchronous cylinders 9 respectively realizes the rotation drive of the two release film rings 10. Finally, it manifests as the synchronous movement of the base sheet 7 and the two release film rings 10. By controlling the running state of the second servo motor 14, the base sheet 7 can be rotated slowly in stages. As the rotation of the base sheet 7 stops, the two light curing lamps 11 are also powered on synchronously to realize the light curing and molding of the printing liquid material filled between the release film ring 10 and the base sheet 7.
[0047] Furthermore, once the base sheet 7 enters the rotating state, both light-curing lamps 11 are de-energized and cease emitting light. This process is repeated to achieve additive manufacturing of the outer periphery of the base sheet 7. During the manufacturing process, the first servo motor 4 works in conjunction, raising the base sheet 7 according to the increase in cured material around it. This ensures that the release film ring 10 maintains tangential contact with the outer periphery of the additively manufactured base sheet 7 until the complete printing of the plastic sheet is achieved. After printing, the first servo motor 4 controls the lifting shell 12 to rise relative to the main shell 1 until the pick-and-place shell 15 is completely removed from the vertical material bin 2. This is because the top of the main shell 1 is designed with a lower front end and a higher rear end. The structure makes it easier to remove and place the shell 15. Compared to the lifting shell 12, the plastic sheet can be removed after removing the shell 15, thus completing the overall manufacturing of the plastic sheet. Since there are two preset holes 20 on the base sheet 7, it is necessary to print filler columns that match the preset holes 20. By inserting and fixing the filler columns into the preset holes 20, the impact of the preset holes 20 on the later use of the plastic sheet can be eliminated. In addition, the preset holes 20 can be designed to correspond to the finished parts of the plastic sheet in the early stages of design modeling and model slicing. That is, the preset holes 20 are the design holes that should be present on the finished material of the plastic sheet, so as to reduce the later finishing work.
