Description

Technical Field

[0001] This utility model relates to the field of UV printer technology, specifically to a cleaning and printing all-in-one machine. Background Technology

[0002] A UV printer is a high-tech, plate-free, full-color digital printer that is not limited by materials and can achieve photo-quality printing on a variety of materials, including T-shirts, cabinet doors, sliding doors, glass, sheets, crystal, PVC, acrylic, metal, plastic, stone, leather, and aluminum composite panels.

[0003] However, despite the broad application prospects of UV printers, certain technical challenges remain when printing on specialized products such as aluminum composite panels (ACPs). The aluminum layer on the surface of ACPs is prone to oxide film formation or contamination with oil, dust, and other pollutants, which directly affects ink adhesion and printing results, potentially leading to blurry images or ink peeling. Therefore, ACPs require pre-treatment cleaning before UV printing to ensure the ink adheres evenly and firmly, achieving optimal print quality and durability. However, most UV printers on the market currently do not integrate pre-treatment cleaning functionality, requiring users to purchase additional cleaning and drying equipment or use manual cleaning and drying methods. This not only increases operational complexity but can also negatively impact final print quality if not handled properly.

[0004] Therefore, it is particularly important to develop a UV printer that integrates cleaning and printing functions to achieve an integrated workflow from material cleaning to printing. Utility Model Content

After the conveyor belt sends the product to be printed to the bottom of the plasma cleaning device, the plasma cleaning device performs plasma cleaning on the surface of the product to be printed, quickly removing organic contaminants from the surface, thereby improving the adhesion of the product and making it easier for the ink to be printed. At the same time, the conveyor belt sends the product to be printed to the bottom of the printing device. Finally, the printing device prints on the processed surface of the product, and the conveyor belt sends the medium out of the cleaning and printing all-in-one machine, completing the printing process.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] This invention provides a cleaning and printing all-in-one machine to solve the problem of how to achieve pre-treatment cleaning.

[0053] See Figure 1 As shown, Figure 1 The image shown is a perspective view of the cleaning and printing all-in-one machine in the embodiment. The cleaning and printing all-in-one machine includes a frame 1, a conveyor belt 2, a plasma cleaning device 3, and a printing device 4.

[0054] The conveyor belt 2 is mounted on the frame 1 and is used to transport the products to be printed.

[0055] The plasma cleaning unit 3 is mounted on the frame 1 and located above the conveyor belt 2. The plasma cleaning unit 3 is used for plasma cleaning of the surface of the product to be printed.

[0056] The printing device 4 is mounted on the frame 1 and located above the conveyor belt 2. The printing device 4 is located downstream of the plasma cleaning device 3 and is used to print the cleaned surface to be printed.

[0057] When using the cleaning and printing all-in-one machine with the above technical solution, firstly, the product to be printed is placed on the conveyor belt 2. After the conveyor belt 2 sends the product to be printed to the bottom of the plasma cleaning device 3, the plasma cleaning device 3 performs plasma cleaning on the surface of the product to be printed, quickly removing organic contaminants from the surface, thereby improving the adhesion of the product and making it easier for the ink to be printed. At the same time, the conveyor belt 2 sends the product to be printed to the bottom of the printing device 4. Finally, the printing device 4 prints on the surface of the product to be printed, while the conveyor belt 2 sends the medium out of the cleaning and printing all-in-one machine, completing the printing process. As can be seen, this cleaning and printing all-in-one machine integrates cleaning and printing functions. Through the plasma cleaning device 3 and the conveyor belt 2, it can realize automatic pre-treatment cleaning of the products to be printed. Combined with the printing device 4, it can realize an integrated operation process from material cleaning to printing. Users do not need to purchase additional cleaning and drying equipment or perform manual cleaning and drying, which greatly reduces the complexity of operation and reduces the impact on printing quality. Compared with the existing liquid cleaning method, this cleaning and printing all-in-one machine uses plasma cleaning device 3 to clean the surface of the products to be printed. After cleaning, printing can be carried out directly without drying, which greatly improves the overall efficiency and is suitable for cleaning products of any shape and material.

[0058] The aforementioned conveyor belt 2 can use an existing motor-belt conveyor mechanism.

[0059] See Figure 1 As shown, in one embodiment of the plasma cleaning device 3, the plasma cleaning device 3 includes a nozzle 31 and a position adjustment component 32. The nozzle 31 is located above the conveyor belt 2 and is used to emit plasma. The position adjustment component 32 is mounted on the frame 1 and connected to the nozzle 31, and is used to adjust the position of the nozzle 31 relative to the conveyor belt 2. In this way, the plasma cleaning device 3 can emit plasma from the nozzle 31 to clean the surface of the product to be printed, thereby achieving automatic pre-treatment cleaning of the product to be printed; and the plasma cleaning device 3 can adjust the position of the nozzle 31 relative to the conveyor belt 2 according to the actual position and area of ​​the surface to be printed, that is, adjust the actual cleaning range of the nozzle 31 on the product to be printed, so as to ensure that the actual cleaning range of the nozzle 31 coincides with the actual surface to be printed, which greatly improves the cleaning effect and applicability of the cleaning and printing all-in-one machine.

[0060] See Figure 2 and Figure 3 As shown, Figure 2 for Figure 1The enlarged schematic diagram at point A shows that, in one embodiment of the position adjustment component 32, the position adjustment component 32 includes a first slide 321, a connecting rod 322, and a second slide 323. The first slide 321 is slidably connected to the frame 1 along the width direction of the conveyor belt 2. The connecting rod 322 includes a first rod portion 3221 and a second rod portion 3222 integrally connected. The first rod portion 3221 is slidably connected to the first slide 321 along the length direction of the conveyor belt 2, and the second rod portion 3222 extends vertically. The second slide 323 is slidably connected to the second rod portion 3222 along the extension direction of the second rod portion 3222 and is connected to the nozzle 31. Fasteners 324 are installed between the first slide 321 and the frame 1, between the first slide 321 and the first rod portion 3221, and between the second rod portion 3222 and the second slide 323. Thus, by sliding the first slide 321, the connecting rod 322, and the second slide 323, the three-dimensional position of the nozzle 31 relative to the conveyor belt 2 can be steplessly adjusted, thereby adjusting the actual cleaning range of the nozzle 31 for different products to be printed, greatly improving the applicability of the cleaning and printing all-in-one machine. After the position is adjusted, the first slide 321 and the frame 1, the first slide 321 and the connecting rod 322, and the connecting rod 322 and the second slide 323 can be fixed by the fastener 324, thereby fixing the three-dimensional position of the nozzle 31 after adjustment, so as to prevent the nozzle 31 from moving during the cleaning process and causing changes in the cleaning range, thereby affecting the cleaning effect of the plasma cleaning device 3.

[0061] The aforementioned first slide 321, connecting rod 322, and second slide 323 can be driven to slide by mechanical equipment or manually. However, if driven by mechanical equipment, the fixing structure of fastener 324 can be eliminated. The aforementioned fastener 324 can use bolts or other threaded components to tightly connect the first slide 321 and the frame 1, the first rod 3221 and the first slide 321, and the second rod 3222 and the second slide 323. Specifically, the tight connection can be achieved by having a bolt pass through and screw into the threaded hole on the first slide 321, and then pressing it tightly against the frame 1.

[0062] Since the product to be printed is usually positioned at the middle of the width of the conveyor belt 2, its printing surface is generally located at the middle position. The conveyor belt 2 transports the product along its length. Therefore, the position of the nozzle 31 in both the length and width of the conveyor belt 2 is generally fixed and will not change. The cleaning range for different products is mainly adjusted by changing the vertical position of the nozzle 31. Manually sliding the second slide 323 can only significantly adjust the vertical position of the nozzle 31, roughly determining its cleaning range. However, precisely adjusting the cleaning range of the nozzle 31 to coincide with the actual printing surface is difficult and time-consuming. Therefore, refer to... Figure 2 and Figure 3As shown, based on the above embodiment, a vertical fine-tuning structure 5 is provided between the second slide 323 and the nozzle 31. The vertical fine-tuning structure 5 includes a mounting base 51 and a fine-tuning screw 52. The mounting base 51 is slidably connected to the second slide 323 in a vertical direction and is fixed to the nozzle 31 by means of screwing or welding. The fine-tuning screw 52 is rotatably connected to the second slide 323 and is screwed to the mounting base 51. The fine-tuning screw 52 has a rotation scale 521. The fine-tuning screw 52 is used to drive the mounting base 51 and the nozzle 31 to slide together relative to the second slide 323 in a vertical direction. In this way, by rotating the fine-tuning screw 52 by a small amount according to the rotation scale 521, the mounting base 51 and the nozzle 31 can be driven to slide together in a small amount in a vertical direction, thereby achieving precise fine-tuning of the vertical position of the nozzle 31 so that the cleaning range of the nozzle 31 can accurately coincide with the actual printing surface, greatly improving the cleaning effect and efficiency of the cleaning and printing all-in-one machine.

[0063] See Figure 1 and Figure 3 As shown, Figure 3 This is a schematic diagram of the adsorption platform, plasma cleaning device, and printing device in the embodiments. Based on any of the above embodiments, the cleaning and printing all-in-one machine further includes an adsorption positioning device 8. The adsorption positioning device 8 includes an adsorption platform 81 and a vacuum mechanism 82. The adsorption platform 81 is fixed to the frame 1 by means of screwing or welding. A conveyor belt 2 is fitted over the outside of the adsorption platform 81, and multiple adsorption holes 21 are evenly distributed on the conveyor belt 2. The adsorption platform 81 has a long strip-shaped guide groove 811, which is opposite to and connected to the adsorption holes 21. The vacuum mechanism 82 is connected to the guide groove 811 and is used to provide a vacuum source for the guide groove 811. Thus, when the vacuum mechanism 82 is activated, it can generate adsorption force by sequentially drawing a vacuum through the guide groove 811 and the adsorption holes 21, and evenly distribute the vacuum on the conveyor belt 2, fixing the product to be printed on the conveyor belt 2, achieving the positioning effect of the product to be printed, and effectively preventing the product to be printed from moving during the entire cleaning and printing process, so as not to affect the cleaning and printing effect. Among them, the adsorption platform 81 can not only transmit the adsorption force to make the adsorption force more uniform, but also support the conveyor belt 2 to prevent the items from sinking on the conveyor belt 2.

[0064] The vacuum pumping mechanism 82 described above can use existing equipment that combines a blower and a negative pressure machine to provide a vacuum source, or it can use equipment such as a vacuum pump to provide a vacuum source.

[0065] See Figure 1As shown, based on the above embodiment, the cleaning and printing all-in-one machine also includes a feed limiting device 6. The feed limiting device 6 is located upstream of the plasma cleaning device 3 and is used to limit the position of the product to be printed in the width direction of the conveyor belt 2. Thus, the feed limiting device 6 can adjust and limit the position of the product to be printed on the conveyor belt 2 after it is input into the conveyor belt 2, and combined with the adsorption positioning device 8, it can fix this position, thereby ensuring the consistency of quality of the same batch of products to be printed.

[0066] See Figure 1 As shown, in one embodiment of the feeding limiting device 6, the feeding limiting device 6 includes a bidirectional screw 61 and two limiting plates 62. The limiting plates 62 slide along the width direction of the conveyor belt 2 on the conveyor belt 2, forming a limiting channel 63 between the two limiting plates 62. The bidirectional screw 61 is rotatably connected to the frame 1, with both ends of the bidirectional screw 61 passing through the two limiting plates 62 respectively and screwed to the two limiting plates 62. The bidirectional screw 61 is used to drive the two limiting plates 62 to move away from or towards each other, thereby expanding or shrinking the width of the limiting channel 63, so that the width of the limiting channel 63 matches the width of the product to be printed on the conveyor belt 2. Thus, rotating the bidirectional screw 61 can drive the two limiting plates 62 to move synchronously towards or away from each other, limiting the product to be printed at the middle position in the width direction of the conveyor belt 2 for subsequent cleaning and printing.

[0067] The aforementioned bidirectional screw 61 can be driven to rotate by a rotary drive device or manually.

[0068] See Figure 1 and Figure 3 As shown, in one embodiment of the printing device 4, the printing device 4 includes a printing carriage 41, a traversing mechanism 42, and a lifting mechanism 43. The printing carriage 41 is located above the conveyor belt 2 and is used to print on the cleaned surface of the product to be printed on the conveyor belt 2. The traversing mechanism 42 is mounted on the frame 1 by means of screwing or welding, and the lifting mechanism 43 is mounted on the output end of the traversing mechanism 42 by means of screwing or welding. The printing carriage 41 is mounted on the output end of the lifting mechanism 43 by means of screwing or welding. The lifting mechanism 43 drives the printing carriage 41 to move vertically relative to the conveyor belt 2, and the traversing mechanism 42 drives the lifting mechanism 43 and the printing carriage 41 to move together along the width direction of the conveyor belt 2. Thus, the traversing mechanism 42, the lifting mechanism 43, and the conveyor belt 2 cooperate to achieve three-dimensional movement of the printing carriage 41 relative to the product to be printed, enabling printing at any position on the surface of the product, thereby achieving large-area printing of the product.

[0069] The aforementioned transverse mechanism 42 and lifting mechanism 43 can use existing linear displacement drive mechanisms such as motor-screw-nut linear modules and linear motor-linear modules.

[0070] The aforementioned print carriage 41 can be an existing UV printer print carriage 41, which can contain several existing print heads. See [reference needed]. Figure 1 As shown, the printheads can be arranged at intervals along the length of the conveyor belt 2 for segmented printing, thereby improving printing efficiency. A cleaning tank 11 is provided on the frame 1 via screws or welding. The cleaning tank 11 is located on one side of the printing device 4, facilitating cleaning of the printheads by the operator.

[0071] See Figure 1 As shown, based on any of the above embodiments, the cleaning and printing all-in-one machine also includes a reinforcement device 7. The reinforcement device 7 is located above the discharge end of the conveyor belt 2. The reinforcement device 7 can use existing UV lamps to reinforce the printed pattern on the product and improve print quality.
