Description

Technical Field

[0001] This utility model relates to the field of ceramic tile printing technology, and in particular to a multi-pass printing machine for matte glazed tiles. Background Technology

[0002] Printing machines are suitable for printing on various materials. After modification, the application range of printing machines has become more extensive, no longer limited to paper printing. In the process of tile production, it is necessary to enhance the aesthetics of the tiles, which requires printing work on them, and this is where printing machines are needed.

[0003] Multi-pass tile printing machines typically use conveyor belts to transport tiles to designated positions, and then perform multiple printing processes on the tile surface through multiple printing units. These printing units can use different printing methods such as roller printing and inkjet printing. However, when using conveyor belts to transport tiles, the power mechanism controlling the movement of the conveyor belt often struggles to achieve precise adjustment of the conveyor belt's position. Yet, during the tile printing process, accurate position control is crucial to prevent errors when printing patterns on the tiles. Therefore, we propose a multi-pass printing machine for matte glazed tiles to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the power mechanism controlling the movement of the conveyor belt is often difficult to precisely adjust the position of the conveyor belt when using it to transport ceramic tiles. Therefore, this invention proposes a multi-pass printing machine for matte glazed tiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-pass printing machine for matte glazed tiles, comprising:

[0007] The rack has a track printer on top;

[0008] The conveyor belt mechanism includes a movable roller, a support roller, and a conveyor belt. The movable roller is adjustablely disposed within a U-shaped bracket, the support roller is rotatably disposed within the frame, and the conveyor belt is sleeved on the movable roller and the support roller.

[0009] The power mechanism includes a drive motor and a transmission screw, wherein the drive motor is fixed on the frame and the transmission screw is connected to the conveyor belt for transmission.

[0010] The transmission screw drives the conveyor belt to move through threaded transmission, thereby achieving precise positioning and conveying of the ceramic tiles.

[0011] In one possible design, the top of the conveyor belt is provided with two baffles, which are arranged in parallel to form a tile limiting channel.

[0012] One possible design also includes:

[0013] An adjusting plate is slidably disposed in the sliding hole of the U-shaped bracket, and the two ends of the movable roller are rotatably connected to the adjusting plate;

[0014] The adjusting screw is rotatably connected to the U-shaped bracket and threadedly engaged with a nut provided on the adjusting plate;

[0015] Rotating the adjusting screw can adjust the position of the moving roller to tension the conveyor belt.

[0016] In one possible design, the frame is provided with a pad located inside the conveyor belt and extending into the U-shaped bracket for supporting the tiles on the conveyor belt.

[0017] In one possible design, the power mechanism further includes:

[0018] A connecting plate is fixed to the bottom of the conveyor belt;

[0019] A threaded ring is fixed to the connecting plate and threadedly engaged with the transmission screw.

[0020] When the transmission screw rotates, it drives the connecting plate to move linearly through the threaded ring.

[0021] In one possible design, a cleaning mechanism is also included, which comprises:

[0022] Mounting bracket, fixed to the support frame;

[0023] The movable plate is slidably disposed within the movable hole of the mounting bracket;

[0024] A rubber scraper is mounted on the bottom of the movable plate via a fixing bracket;

[0025] An electric push rod drives the moving plate to move up and down.

[0026] The rubber scraper cleans the moving tile printing surface by contacting it as it descends.

[0027] In one possible design, there are two electric actuators, symmetrically mounted on both sides of the mounting bracket.

[0028] In this application, before use, by rotating the adjusting screws on both sides, the adjusting plate can be moved under the threaded transmission action with the corresponding nuts. This causes the moving roller to move laterally. If the conveyor belt becomes loose, the position of the moving roller can be adjusted to tighten the conveyor belt. Thus, the moving roller and support roller can provide stable support for the conveyor belt. Then, the tile is placed on the conveyor belt and positioned within the two stop bars. Next, the drive motor is started to rotate the transmission screw. Under the threaded transmission action with the threaded ring, the connecting plate can be moved laterally. The movement of the connecting plate generates tension on the conveyor belt, causing the conveyor belt to move around the moving roller and support roller. The movement of the conveyor belt allows the tiles to be transported into the frame. Simultaneously, two electric push rods can be activated to move the moving plate downwards, which in turn moves the rubber scraper downwards, bringing it into contact with the printing surface of the tile. This scrapes and cleans the printing surface of the moving tile, removing any loose dust. After cleaning, when the tile moves to the bottom of the track printer, the track printer can be activated to apply the pattern to the tile. The conveyor belt is driven by a threaded drive, which has good precision, ensuring accurate movement of the tile and preventing errors during pattern application.

[0029] Beneficial effects: In this utility model, the multi-pass printing machine for matte glazed tiles can move after the conveyor belt receives the driving force of the power mechanism. Therefore, when the tile is placed on the conveyor belt and located within the two baffles, the tile can be moved laterally to the bottom of the track printer, and the track printer can be used to print the pattern on the tile.

[0030] In this utility model, the matte glazed tile multi-pass printing machine can drive the transmission screw to rotate by starting the drive motor through the power mechanism. At this time, under the action of the thread transmission with the threaded ring, the connecting plate can be moved laterally. When the connecting plate moves, it can generate a pulling force on the conveyor belt, so that the conveyor belt can move around the moving roller and the support roller, thereby transporting the ceramic tile.

[0031] In this utility model, the matte glazed tile multi-pass printing machine, through the cleaning mechanism, can drive the moving plate downward by starting the electric push rod, thereby driving the rubber scraper downward so that the rubber scraper contacts the printing surface of the tile, thereby scraping and cleaning the printing surface of the moving tile, and cleaning the existing dust.

[0032] This invention uses a drive motor to move a conveyor belt, thereby moving the position of the tile. The drive method used is threaded transmission, which has good precision. Therefore, when moving the tile, it can maintain accurate movement, thus preventing errors when applying printed patterns. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] Example 1: Refer to Figure 1-4 A printing machine comprises a frame 1, a track printer 15, a support frame 2, a U-shaped bracket 3, a conveyor belt mechanism, a power mechanism, and a cleaning mechanism. The track printer 15 is mounted on the top of the frame 1. The support frame 2 is welded to one side of the frame 1, and the U-shaped bracket 3 is welded to the support frame 2. A conveyor belt mechanism is installed inside the U-shaped bracket 3, with one side extending into the frame 1 and connecting to the inner wall of the frame 1. The power mechanism is installed inside the frame 1, with one side extending into the support frame 2 and connecting to the support frame 2, and its top connected to the conveyor belt mechanism. The cleaning mechanism on the U-shaped bracket 3 is used to clean the tile printing area.

[0040] The conveyor belt mechanism includes a movable roller 5 within a U-shaped bracket 3 and a support roller 6 rotatably connected within a frame 1. The movable roller 5 and support roller 6 are driven by the same conveyor belt 7. The bottom of the conveyor belt 7 is connected to a power mechanism, and two baffles 21 are attached to its top. When a tile is placed on the conveyor belt 7 between the two baffles 21, the conveyor belt 7 begins to move after receiving driving force from the power mechanism. The tile then moves laterally to below the track printer 15, where the track printer 15 can then apply a pattern to the tile.

[0041] The inner walls of both sides of the U-shaped bracket 3 have sliding holes through which adjusting plates 4 slide. The two ends of the moving roller 5 are rotatably connected to the two adjusting plates 4 respectively. A nut 14 is welded to one side of the adjusting plate 4, located on the outside of the U-shaped bracket 3. An adjusting screw 13 is threaded through the nut 14 and passes through the adjusting plate 4, rotatably connecting to one side of the U-shaped bracket 3. Rotating the adjusting screw 13, through the threaded transmission with the nut 14, moves the adjusting plate 4, thereby causing the moving roller 5 to move laterally. When the conveyor belt 7 becomes loose, adjusting the position of the moving roller 5 can tighten the conveyor belt 7, achieving stable support for the conveyor belt 7 by the moving roller 5 and the support roller 6.

[0042] A pad 8 is welded inside the frame 1 and located within the conveyor belt 7. One side of the pad 8 extends into the U-shaped bracket 3, and its two sides are welded to the inner walls of the U-shaped bracket 3. After the tile is placed on the conveyor belt 7, the pad 8 assists the conveyor belt 7 in supporting the tile, ensuring that the tile can move horizontally.

[0043] The power mechanism consists of a drive motor 9 bolted to the other side of the frame 1. The output shaft of the drive motor 9 extends into the frame 1 and is welded with a transmission screw 10. A connecting plate 11 is bolted to one side of the bottom of the conveyor belt 7. A threaded ring 12 is welded to one side of the connecting plate 11. The transmission screw 10 passes through the connecting plate 11 and the threaded ring 12 and is threadedly connected to the threaded ring 12. One end of the transmission screw 10 extends into the support frame 2 and is rotatably connected to the support frame 2. When the drive motor 9 is started, it drives the transmission screw 10 to rotate. Through the threaded transmission with the threaded ring 12, it drives the connecting plate 11 to move laterally. The movement of the connecting plate 11 generates tension on the conveyor belt 7, causing the conveyor belt 7 to move around the moving roller 5 and the support roller 6, thus completing the transport of the tiles.

[0044] This application can be used in the field of tile printing technology, or in other fields applicable to this application.

[0045] Example 2: Reference Figure 1 and 4An improvement upon Embodiment 1: A multi-pass printing machine for matte glazed tiles, applied to the field of tile printing technology, includes a cleaning mechanism comprising a mounting frame 16 welded to a support frame 2. Movable holes are formed on the inner walls of both sides of the mounting frame 16, through which a single movable plate 17 is slidably connected. A fixed frame 18, located within the mounting frame 16, is welded to the bottom of the movable plate 17. A rubber scraper 19 is detachably mounted on the bottom of the fixed frame 18. Electric push rods 20 are bolted to the bottom of both sides of the mounting frame 16, and the output shaft of the electric push rods 20 is fixedly connected to the bottom of the movable plate 17. Activating the electric push rods 20 moves the movable plate 17 downwards, causing the rubber scraper 19 to move downwards and contact the tile printing surface. During the continuous movement of the tile, the rubber scraper 19 scrapes and cleans the tile printing surface, removing surface dust.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 9, the track printer 15, and the electric push rod 20 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] 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.
