Description

Technical Field

[0001] The present invention relates to the technical field of printing and forming devices, and more particularly to a printing and forming device for plastic sheet processing. Background Art

[0002] As is well known, additive manufacturing technology is an advanced manufacturing technology based on a digital model that constructs a three-dimensional entity by layer-by-layer material deposition. Its principle is to divide a designed three-dimensional model into a series of two-dimensional thin slices through slicing software, and then a 3D printer adds and cures materials layer by layer according to the contour information of these thin slices to finally form a complete three-dimensional object. A printing and forming device for plastic sheet processing is a 3D printing and forming device that assists in plastic sheet processing.

[0003] After retrieval, the patent with Chinese Patent Publication No. CN105835372A and the patent with Chinese Patent Publication No. CN105643936A respectively disclose a 3D printer and a full-color 3D printer. The former is generally described as including a mounting frame, an extrusion device, a displacement device, a discharging device, and a processing platform. The discharging device includes a wire outlet mounting seat, an upper wire outlet pipe, a lower wire outlet pipe, a wire outlet motor, a wire outlet driving wheel, and a wire outlet auxiliary wheel. The outer peripheral surfaces of the wire outlet driving wheel and the wire outlet auxiliary wheel form a wire transmission cavity. The wire outlet auxiliary wheel is rotatably engaged with the wire outlet mounting seat. The wire outlet motor drives the wire outlet driving wheel to rotate. The upper wire outlet pipe and the lower wire outlet pipe are provided for the printing material to pass through and are sequentially arranged vertically on the wire outlet mounting seat. A wire transmission interval is provided between the upper wire outlet pipe and the lower wire outlet pipe, and this wire transmission interval corresponds to the position of the wire transmission cavity. A swing arm is provided on the wire outlet mounting seat. An adjusting bolt is arranged along the swing direction of the swing arm. A limiting nut and a limiting retaining ring are arranged on the adjusting bolt. The latter is generally described as including a support platform, an X-axis guide rail, a Y-axis guide rail, a Z-axis guide rail, a printing platform, a lifting platform, a driving lead screw, a printing nozzle, a light curing device, a support plate, a first material tank, a second material tank, a third material tank, a fourth material tank, a feeding conduit, a UV lamp, a light quantity adjusting device, a plurality of micro nozzles, a plurality of longitudinal baffles, and a transverse baffle. When in use, a three-dimensional solid model of a three-dimensional solid object to be printed is designed by a computer, and the three-dimensional solid model of the three-dimensional solid object is sliced and layered along the internal direction of the computer corresponding to the actual vertical direction to obtain the forming data of each layer. The computer controls the movement of the printing nozzle and sprays a photosensitive resin liquid in the area corresponding to the printing platform, and cures it under the irradiation of the UV lamp, thereby obtaining the bottom layer of the three-dimensional solid object on the printing. The printing nozzle moves upward, and then prints layer by layer, and finally prints out the three-dimensional solid object. Each micro nozzle corresponds to a photosensitive resin liquid of a different color. According to the printing needs, different colors can be replaced, and two different colors can also be mixed to configure more colors to meet the needs of users, thereby realizing 3D full-color printing.

[0004] Although the above two prior art solutions can both achieve additive manufacturing, the workbench formed by supporting additive manufacturing is more suitable for printing general parts, that is, parts with coordinated length, width and height.

Through the provision of the lifting clamping assembly, it is convenient to form a structure for the plastic sheet to be processed that can be lifted and adjusted and rotationally driven, facilitating the necessary motion drive for the printing operation of the plastic sheet to be printed.

[0042] It should be further explained that there are two pairs of insertion rods 22 slidingly connected in the pick-and-place shell 15, and the two pairs of insertion rods 22 are slidably connected to the pick-and-place shell 15.

The plurality of guide rails 30 are respectively matched with the plurality of guide rail sleeves 31, and the front ends of the plurality of guide rail sleeves 31 are all provided with guide wide openings 32. When the pick-up and placement shell 15 is installed relative to the lifting shell 12, the plurality of guide rails 30 can be respectively inserted into the plurality of guide rails 30 to achieve the alignment insertion between the pick-up and placement shell 15 and the lifting shell 12, and the vertical material A front horizontal support frame 33 is fixedly connected in the warehouse 2, and two rear horizontal support grooves 34 are provided in the vertical material warehouse 2.

[0043] It should be further noted that the processing platform includes two support frames 8, both of which are installed in the vertical silo 2. Synchronous cylinders 9 are rotatably connected to the outside of the two support frames 8, and release film rings 10 are detachably installed on the outside of the two synchronous cylinders 9. The installation of the release film ring 10 relative to the synchronous cylinder 9 is assisted by auxiliary pressure rings at both ends. That is, the release film ring 10 is first put on the synchronous cylinder 9, and then the auxiliary pressure rings are sleeved on the steps at both ends of the synchronous cylinder 9. After that, the auxiliary pressure rings are fixedly connected to the synchronous cylinder 9 through bolts. Light curing lamps 11 are arranged in both of the two synchronous cylinders 9, and the two light curing lamps 11 are respectively installed in the two support frames 8. The two light curing lamps 11 can respectively irradiate on the two release film rings 10 through the two synchronous cylinders 9. A synchronous structure is arranged between the two synchronous cylinders 9 and the base sheet 7. Through the design of the processing platform, functional components for curing and forming plastic sheets are provided, and the curing efficiency is further improved in the form of multi-point curing. The synchronous structure includes a synchronous belt 38, and the synchronous belt 38 is drivingly connected to a driving wheel 39, two fixed wheels 40 and two follower wheels 41.

Through the design of the synchronous structure, synchronous rotation is formed between the base sheet 7 and the synchronous cylinder 9. At the same time, when the base sheet 7 rises or falls, the distance between the two synchronous cylinders 9 can also be adjusted followingly, so as to facilitate an appropriate printing distance between the two light curing lamps 11 and plastic sheets of different sizes.

A driving sleeve 47 is threadedly connected to the vertical lead screw 45, and the driving sleeve 47 is fixedly connected to the lifting frame 6.

The driving bevel gear 48 meshes with a transmission bevel gear 49, and the transmission bevel gear 49 is fixedly connected to the driving frame 13, providing a specific technical solution for the driving function between the first servo motor 4 and the lifting frame 6, and also providing a specific technical solution for the transmission function between the second servo motor 14 and the driving frame 13.

[0044] The light curing lamp 11, the first servo motor 4 and the second servo motor 14 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them and do not improve their structures and functions. For those skilled in the art, their setting methods, installation methods and electrical connection methods only need to be debugged and operated according to the requirements of their user manuals, and will not be elaborated here.

[0045] In summary, the working principle of the printing and forming device for processing plastic sheets is as follows: when in use, the printing and forming device for processing plastic sheets is first installed at the place of use; during the installation process, the main body shell 1 is fixed by the flange surrounding the bottom of the main body shell 1; after the positioning is completed, the first servo motor 4, the second servo motor 14 and the two light-curing lamps 11 are electrically installed; during the electrical installation, the controller should be debugged and installed; the operation control of the first servo motor 4, the second servo motor 14 and the two light-curing lamps 11 can be realized through the controller; the basic sheet 7 is made in advance; the production of the basic sheet 7 can be achieved by a general 3D printer; then the first servo motor 4 is controlled to be powered on and run, and the first servo motor 4 is powered on to realize the rotation drive of the vertical screw 45; under the transmission action of the drive sleeve 47, the rotation of the vertical screw 45 can realize the height adjustment of the lifting frame 6; the lifting frame 6 is controlled to rise to realize the complete extraction of the pick-up and placement shell 15 relative to the main body shell 1; and the two insertion rods are realized by toggling the toggle bar 24. The two pairs of rods 22 are respectively pulled out of the two slots 23, and the two pairs of insertion rods 22 are kept in the state of escaping from the two slots 23, so that the pick-up and placement shell 15 is pulled out from the lifting frame 6. Then, the pre-prepared basic sheet 7 is placed and installed on the insertion column 17, so that the two insertion columns 17 are respectively inserted into the two preset holes 20. Then, the pick-up and placement shell 15 is inserted into the lifting frame 6 again, so that the basic sheet 7 is in close contact with the driving frame 13, and the insertion column 17 is controlled to be inserted into the two insertion grooves 21. When the pick-up and placement shell 15 is installed in place relative to the lifting frame 6, the two pairs of insertion rods 22 will be respectively inserted into the two pairs of insertion slots 23, thereby realizing the re-positioning of the pick-up and placement shell 15 in the lifting shell 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 column 17. On the one hand, it can adapt to the thickness of the supporting basic sheet 7, and on the other hand, it can further press the supporting basic sheet 7 to prepare for subsequent printing operations.

[0046] Further, printing liquid material is added into the vertical silo 2. Then, the first servo motor 4 is powered on to work, causing the height of the lifting shell 12 to decrease. The lifting shell 12 and the picking and placing shell 15 are integrally inserted into the vertical material groove. Since the decrease in the height of the lifting shell 12 can achieve the synchronous decrease of the driving wheel 39, and the decrease in the height of the driving wheel 39 can further press the synchronous belt 38, the relative distance between the corresponding two follower wheels 41 will be closer. This is convenient for the release film ring 10 to approach and fit closely to the relatively small base sheet 7 at the initial stage of printing. Until both release film rings 10 come into contact with the base sheet 7, the first servo motor 4 enters the stop state to maintain the relative height of the lifting shell 12. Then, the second servo motor 14 is powered on and runs to drive the rotation of the vertical rotating shaft 46. Under the meshing transmission of the driving bevel gear 48 and the transmission bevel gear 49, the rotation of the vertical rotating shaft 46 can drive the rotation of the driving frame 13. The rotation of the driving frame 13 can drive the rotation of the base sheet 7 in contact and pressed by it. While the driving frame 13 rotates, it will also drive the driving wheel 39 to rotate. The rotation of the driving wheel 39 drives the synchronous rotation of the two synchronous cylinders 9 through the synchronous belt 38. The rotation of the two synchronous cylinders 9 respectively drives the rotation of the two release film rings 10. Finally, it is manifested as the synchronous movement of the base sheet 7 and the two release film rings 10. By controlling the operating state of the second servo motor 14, the base sheet 7 rotates slowly in stages. Along with the pause of the rotation of the base sheet 7, the two photocuring lamps 11 are also powered on and run synchronously to achieve the photocuring and forming of the printing liquid material filled between the release film ring 10 and the base sheet 7 outside the release film ring 10.

[0047] Furthermore, after the base sheet 7 enters the rotating state, both of the photocuring lamps 11 are powered off and stop emitting light. This process is repeated to achieve additive manufacturing on the periphery of the base sheet 7. During the manufacturing process, the first servo motor 4 will work in coordination. As the curing material around the base sheet 7 increases, the height of the base sheet 7 rises, so that the release film ring 10 can maintain tangential contact with the periphery of the base sheet 7 after additive manufacturing until the complete printing and forming of the plastic sheet is completed. After printing is completed, by the operation of the first servo motor 4, the lifting housing 12 is controlled to rise in height relative to the main body housing 1 until the picking and placing housing 15 is completely withdrawn from the vertical material bin 2. Since the top of the main body housing 1 has a structure that is lower at the front end and higher at the rear end, it is more convenient for the corresponding operation of the picking and placing housing 15. After the picking and placing housing 15 is removed relative to the lifting housing 12 again, the plastic sheet can be taken off, thus completing the overall manufacturing of the plastic sheet. Since there are two preset holes 20 provided on the base sheet 7, if necessary, filling columns matching the preset holes 20 can be printed, and the filling columns are inserted and fixed in the preset holes 20 to eliminate the influence of the preset holes 20 on the later use of the plastic sheet. Also, in the initial stage of design modeling and model slicing, corresponding designs can be made for the preset holes 20 corresponding to the finished parts of the plastic sheet, that is, the preset holes 20 are the design holes that should be present in the finished material of the plastic sheet, so as to reduce the later trimming operations.
