Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial printer technology, specifically a new type of industrial-grade printer. Background Technology
[0002] The working principle of an industrial-grade FDM 3D printer is to heat a filament of thermoplastic material to a molten state, then extrude the material through a nozzle, layer by layer, following a pre-designed 3D model path to form a 3D solid model. The 3D model of the desired object is created using 3D modeling software, or its 3D data is obtained through 3D scanning. Then, the 3D model is imported into the 3D printer's control system. The slicing software in the control system cuts the 3D model into a series of very thin 2D slices along the Z-axis. These slices serve as the basis for the printer to print layer by layer. Each slice contains the contour and infill information of that layer, thus completing the printing process.
[0003] Traditional industrial printers often use a structure where the X and Y axes are fixed at the highest point of the printing area, with the printing platform rising and falling. Due to its high center of gravity and the high position of moving parts, this structure suffers from inherent instability when printing at high speeds or on large objects. Another approach is to fix the platform at the bottom, with the Z-axis driving the Y-axis up and down. This structure offers significantly improved stability compared to the previous one, but it requires four Z-axis lifting mechanisms for stable operation. Such structures are not only costly but also have high tolerances for error and a high failure rate.
[0004] Therefore, those skilled in the art have provided a novel industrial-grade printer to address the problems mentioned in the background section. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a novel industrial-grade printer. This industrial printer has a lower cost than the traditional 4Z-axis structure and avoids mechanical jamming caused by low assembly precision. The Y-axis center of gravity and Z-axis moving parts are fixed in a cross shape, and the Y-axis is connected and fixed by an optical axis slide rail. Advantages: low cost, good stability, no mechanical jamming, ensuring long-term good use of the industrial printer, improving service life, and indirectly improving printer efficiency. At the same time, by setting up a moving mechanism, lubricating oil can be added automatically by increasing the coefficient of friction, which is very convenient and avoids wear caused by long-term friction, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A novel industrial-grade printer includes a printer frame. Vertical plates are fixedly connected to both the left and right sides of the printer frame. Z-axis components are provided inside each of the two vertical plates. Y-axis components are provided on the adjacent surfaces of the two Z-axis components. X-axis components are provided on the two Y-axis components. Two limiting rods are fixedly connected to both the left and right sides of the printer frame. Each pair of limiting rods is located on both sides of a single vertical plate. Limiting blocks are fixedly connected to the opposite sidewalls of the adjacent surfaces of the two Y-axis components. The limiting blocks are sleeved on the limiting rods.
[0008] As a further embodiment of this utility model, the limiting block is provided with an active mechanism, the active mechanism including a slide groove opened inside the limiting block, a slide plate slidably connected inside the slide groove, a tensioner fixedly connected inside the slide groove, the slide plate and the tensioner being connected by a connecting rod, and the tensioner being located above the slide plate.
[0009] As a further embodiment of this utility model, the movable mechanism also includes a storage cylinder fixedly installed on the limiting block. The limiting block has a cylindrical groove, and the storage cylinder is provided with a flexible tube that passes through the interior of the cylindrical groove.
[0010] As a further embodiment of this utility model, a control component is provided inside the limiting block, and a solenoid valve is provided at the outlet of the hose. The control component is electrically connected to the solenoid valve and the tensioner.
[0011] As a further improvement of this utility model, a friction strip is fixedly connected to the side wall of the slide plate near the limiting rod, so that the slide plate can move inside the slide groove due to friction.
[0012] As a further improvement of this utility model, rollers are fixedly installed at the lower corners of the printer frame, which allows the printer frame to be moved easily.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This industrial printer is less expensive than the traditional 4Z axis structure and avoids mechanical jamming caused by low assembly precision. The Y-axis center of gravity and Z-axis moving parts are fixed in a cross shape, and then the Y-axis is connected and fixed by an optical axis slide rail. Advantages: low cost, good stability, no mechanical jamming, ensuring long-term good use of the industrial printer, extending its service life, and indirectly improving the printer's working efficiency. At the same time, by setting up a moving mechanism, lubrication can be automatically added by increasing the friction coefficient, which is very convenient and avoids wear caused by long-term friction affecting use.

[0020] Please see Figures 1-4 In this embodiment of the invention, a novel industrial-grade printer includes a printer frame 1. Vertical plates 2 are fixedly connected to both the left and right sides of the printer frame 1. Z-axis components 5 are provided inside each of the two vertical plates 2. The adjacent surfaces of the two vertical plates 2 are notched. Y-axis components 6 are provided on the adjacent surfaces of the two Z-axis components 5. X-axis components 7 are mounted on the two Y-axis components 6. This design is lower in cost than the traditional 4Z-axis structure and avoids mechanical jamming caused by low assembly precision. The center of gravity of the Y-axis component 6 and the moving parts of the Z-axis component 5 are fixed in a cross shape, and then the Y-axis component 6 is connected and fixed using an optical axis slide rail. This design is low in cost, has good stability, and eliminates mechanical jamming.
[0021] Two limiting rods 3 are fixedly connected to both the left and right sides of the printer frame 1. Each pair of limiting rods 3 is located on both sides of the vertical plate 2. Two limiting blocks 4 are fixedly connected to the opposite surfaces of the adjacent surfaces of the two Y-axis components 6. The limiting blocks 4 are sleeved on the limiting rods 3. When the Y-axis component 6 moves up and down, the limiting blocks 4 move synchronously along the limiting rods 3 to ensure the stability of its movement.
[0022] The inner wall of the limiting block 4 is provided with a sliding groove 8. A tensioner 10 is fixedly connected inside the sliding groove 8. A sliding plate 9 is slidably connected inside the sliding groove 8. The sliding plate 9 can move up and down based on the sliding groove 8. The sliding plate 9 and the tensioner 10 are connected by a connecting rod 11. When the limiting block 4 moves based on the limiting rod 3, if the lubrication between the two is insufficient and the lubrication coefficient is too high, the sliding plate 9 will move and pull on the tensioner 10.
[0023] A storage cylinder 17 is installed on the limiting block 4. The inside of the storage cylinder 17 is used to store lubricating oil. A cylindrical groove 13 is opened on the limiting block 4. A hose 14 is provided at the outlet of the storage cylinder 17. One end of the hose 14 passes through the cylindrical groove 13 and can contact the surface of the limiting rod 3. The lubricating oil inside can flow out through the hose 14 to lubricate the limiting rod 3 and the limiting block 4. A solenoid valve 15 is provided at the outlet of the hose 14. A control component 16 is provided on the limiting block 4. The control component 16 is electrically connected to the solenoid valve 15 and the tensioner 10. When the tensioner 10 is pulled due to excessive friction, it will send a signal to the control component 16. The control component 16 can open the solenoid valve 15 to ensure that the lubricating oil flows out.
[0024] The surface of the slide plate 9 that contacts the limit rod 3 is provided with friction strips 12 to facilitate the pulling of the tensioner 10.
[0025] A roller 18 is fixedly installed at the lower corner of the printer frame 1, which allows the printer to be moved easily.
[0026] The working principle of this utility model is as follows: This industrial printer has a lower cost than the traditional 4Z axis structure and does not suffer from mechanical jamming caused by low assembly precision. The Y-axis center of gravity and the Z-axis moving parts are fixed in a cross shape, and then the Y-axis is connected and fixed by an optical axis slide rail. Advantages: low cost, good stability, no mechanical jamming, greatly improving the practicality of the industrial printer. When the printer is used for a long time, frequent friction will occur between the limit rod 3 and the limit block 4. In order to avoid the friction affecting the use of the printer, lubricating oil needs to be added regularly. When the friction coefficient between the limit rod 3 and the limit block 4 increases, the slide plate 9 moves based on the slide groove 8 under the influence of friction, thereby pulling the tensioner 10. When the tensioner 10 has a numerical display, it will send a signal to the control component 16. The control component 16 will open the solenoid valve 15. At this time, the lubricating oil stored in the storage cylinder 17 can flow through the hose 14 to the space between the limit rod 3 and the limit block 4 for lubrication. When a certain amount of lubricating oil flows out, the solenoid valve 15 closes to avoid wasting lubricating oil.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
