Description

Technical Field

[0001] The present application relates to an inkjet printer with an open-loop mesh belt and a method of using the same. Background Art

[0002] For large-scale inkjet printers, they generally include inkjet structures and mobile mechanisms. The inkjet structure is more common, and the overall structure can already meet the printing requirements. However, for the mobile mechanism, different materials need to be adapted to meet the printing requirements. At present, for flexible materials, auxiliary transmission devices are generally adapted, and negative pressure adsorption is set in the transmission device to ensure the stability of the flexible materials during use. For strip materials, transmission belts or similar transmission belts are now mostly used for adsorption stepping to ensure the stability of the position and tension state of the flexible materials during use. However, this method has many disadvantages. On the one hand, there is the problem of cleaning the transmission belt, which is difficult to clean after clogging. On the other hand, it is difficult to combine with water cooling and other methods, and the water cooling effect cannot be guaranteed. In addition, for some breathable fabrics, inkjet printers equipped with transmission belts cannot be used and cannot complete inkjet printing operations. Summary of the invention

[0003] In order to solve the above problems, the present application proposes a spray printer with an open-loop mesh belt, including a printing platform, a print head is arranged above the printing platform, and a first auxiliary wheel group and a second auxiliary wheel group are arranged on both sides of the print head; the first auxiliary wheel group includes a first transmission roller for introducing a printing substrate and a first auxiliary roller for introducing an auxiliary mesh belt, and the first auxiliary roller is arranged below the first transmission roller; the second auxiliary wheel group includes a second transmission roller for exporting a printing substrate and a second auxiliary roller for exporting an auxiliary mesh belt, and the second auxiliary roller is arranged below the second transmission roller. The present application adopts an open-loop introduction auxiliary mesh belt, which is easy to adjust first and is not easy to deviate compared to a closed-loop mesh belt. Secondly, the mesh belt and the adsorption cavity are easy to clean. Thirdly, since there is no need to adjust the tension with the support shaft part, a thin mesh belt can be used, which has a low tolerance and higher precision, and is not easy to cause the printing substrate to be adsorbed into the mesh belt pores and affect the printing quality.

[0004] Preferably, it also includes a first mesh belt roller and a second mesh belt roller, and an auxiliary mesh belt is arranged between the first mesh belt roller and the second mesh belt roller. The auxiliary mesh belt passes between the first auxiliary roller and the first transmission roller, and then enters the printing platform after being attached to the printing substrate on the first transmission roller.

[0005] Preferably, it further comprises a first material roller and a second material roller, a printing substrate is arranged between the first material roller and the second material roller, and the printing substrate passes through the first transmission roller, the printing platform and the second transmission roller in sequence.

[0006] Preferably, the first material roller and the first mesh belt roller are arranged in cooperation with each other relative to the first auxiliary wheel group, and the auxiliary mesh belt introduction position on the first material roller and the introduction position of the printing substrate on the first mesh belt roller are arranged on the opposite sides relative to the first auxiliary wheel group;

[0007] The second material roller and the second mesh belt roller are arranged in coordination with the second auxiliary wheel group, and the lead-out position of the auxiliary mesh belt on the second material roller and the lead-out position of the printed substrate on the second mesh belt roller are arranged on the opposite side relative to the second auxiliary wheel group. The first material roller and the second material roller of the present application respectively realize the supply of the printed substrate and the recovery after printing, while the first mesh belt roller and the second mesh belt roller realize the supply and recovery of the imported auxiliary mesh belt. By designing the positions of the mesh belt roller, the material roller and the two auxiliary wheel groups, the compounding and separation of the printed substrate and the auxiliary mesh belt are automatically realized. This independent control method is also adopted, which makes it easier to effectively intervene and control the shape of the printed substrate on the auxiliary mesh belt.

[0008] Preferably, the printing platform includes an adsorption cavity, a negative pressure fan is arranged at the lower part of the adsorption cavity, and the negative pressure fan is connected to the adsorption cavity.

[0009] Preferably, a water cooling part is also provided in the adsorption chamber, and the water cooling part is provided on the top of the adsorption chamber;

[0010] The water cooling part includes a water cooling pipe that is arranged in close contact with the adsorption cavity, and the water cooling pipe is connected to the cold water supply box through a cold water pump. Since the auxiliary mesh belt used in the present application does not need to bear the tensioning function provided by the two support rollers, the auxiliary mesh belt of the present application can be made of a relatively thin material, so it will not affect the water cooling effect, which is more conducive to the use of certain inkjet printers that require cooling, and ensures the inkjet quality and inkjet effect of the pattern on the printed substrate during use.

[0011] Preferably, the mesh belt is a non-metallic breathable mesh belt or a non-woven fabric belt.

[0012] Preferably, the print head includes a print slider, a plurality of print nozzles are arranged below the print slider, a drive screw is connected to the print slider in a power manner, and a drive motor is arranged on one side of the drive screw.

[0013] On the other hand, the present application also proposes a method for using an inkjet printer with an open-loop mesh belt, comprising the following steps:

[0014] Choose whether to use it with the auxiliary mesh belt according to the air permeability of the printing substrate;

[0015] If the printed substrate itself is air-permeable, the auxiliary mesh belt is removed from the first auxiliary wheel set and the second auxiliary wheel set;

[0016] Then the printing substrate passes through the first transmission roller and the second transmission roller and the printing platform therebetween, and then is spray-printed by the print head;

[0017] If the printing substrate itself is not air-permeable, the auxiliary mesh belt passes between the first transmission roller and the first auxiliary roller, and then is combined with the printing substrate on the outer side of the first transmission roller relative to the printing platform, and then enters the printing platform, and then enters the second transmission roller after printing by the print head;

[0018] On the outer side of the second transmission roller relative to the printing platform, the auxiliary mesh belt and the printing substrate are separated, and the auxiliary mesh belt is guided out of the second auxiliary wheel group after passing between the second transmission roller and the second auxiliary roller, while the printing substrate is directly guided out of the second auxiliary wheel group after separation. This application can quickly determine whether the auxiliary mesh belt needs to be set according to whether the printing substrate is breathable. When the printing substrate is breathable but has a certain rigidity, the first transmission roller and the second transmission roller can be directly used for inkjet printing. When the printing substrate is not breathable, even if it has a certain flexibility, under the adsorption effect of the auxiliary mesh belt, negative pressure adsorption can be performed with the help of the adsorption cavity under the printing platform, so as to further ensure the flatness of the printing substrate, thereby ultimately ensuring that the required inkjet printing products are obtained.

[0019] Preferably, for the air permeability of the printed substrate, if the air permeability is less than 10 mm / s, it is considered to have no air permeability, otherwise it is considered to have air permeability;

[0020] When the printing substrate is air permeable, the printing substrate first passes between the first transmission roller and the first auxiliary roller, and then is spray-printed through the printing platform under the guidance of the first transmission roller, and then is guided by the second transmission roller and enters between the second transmission roller and the second auxiliary roller to be completely printed.

[0021] This application can bring the following beneficial effects:

[0022] 1. The first material roller and the second material roller of the present application respectively realize the supply of the printed substrate and the retraction after printing, while the first mesh belt roller and the second mesh belt roller realize the supply and retraction of the imported auxiliary mesh belt. Through the design of the positions of the mesh belt roller, the material roller and the two auxiliary wheel groups, the compounding and separation of the printed substrate and the auxiliary mesh belt are automatically realized. This independent control method is also adopted, which makes it easier to effectively intervene in and control the shape of the printed substrate on the auxiliary mesh belt.

[0023] 2. Since the auxiliary mesh belt used in the present application does not need to bear the tensioning function of the two support rollers, the auxiliary mesh belt of the present application can be made of a relatively thin material, so it will not affect the water cooling effect. This is more beneficial for the use of certain inkjet printers that require cooling, and ensures the inkjet quality and inkjet effect of the pattern on the printed substrate during use.

[0024] 3. The present application can quickly determine whether an auxiliary mesh belt is needed according to whether the printing substrate is breathable. When the printing substrate is breathable but has a certain rigidity, the first transmission roller and the second transmission roller can be directly used for inkjet printing. When the printing substrate is not breathable, even if it has a certain flexibility, under the adsorption effect of the auxiliary mesh belt, negative pressure adsorption can be performed with the help of the adsorption cavity under the printing platform to further ensure the flatness of the printing substrate, thereby ultimately ensuring that the inkjet printing product that meets the requirements is obtained.

[0030] In order to clearly illustrate the technical features of the present solution, the present application is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0031] like Figure 1-Figure 4 As shown, a spray printer with an open-loop mesh belt includes a printing platform 1, a print head 2 is arranged above the printing platform 1, and a first auxiliary wheel group 3 and a second auxiliary wheel group 4 are respectively arranged on both sides of the print head 2; the first auxiliary wheel group 3 includes a first transmission roller 8 for introducing a printing substrate 5 and a first auxiliary roller 7 for introducing an auxiliary mesh belt 6, and the first auxiliary roller 7 is arranged below the first transmission roller 8; the second auxiliary wheel group 4 includes a second transmission roller 9 for exporting the printing substrate 5 and a second auxiliary roller 10 for exporting the auxiliary mesh belt 6, and the second auxiliary roller 10 is arranged below the second transmission roller 9.

[0032] The auxiliary mesh belt 6 part includes a first mesh belt roller 11 and a second mesh belt roller 12. An auxiliary mesh belt 6 is arranged between the first mesh belt roller 11 and the second mesh belt roller 12. The auxiliary mesh belt 6 passes between the first auxiliary roller 7 and the first transmission roller 8, and then enters the printing platform 1 after being attached to the printing substrate 5 on the first transmission roller 8.

[0033] The printing substrate 5 part also includes a first material roller 13 and a second material roller 14, and the printing substrate 5 is arranged between the first material roller 13 and the second material roller 14. The printing substrate 5 passes through the first transmission roller 8, the printing platform 1, and the second transmission roller 9 in sequence.

[0034] In order to better complete the introduction and guidance of the auxiliary mesh belt 6 and the introduction and guidance of the printed substrate 5, as well as the attachment of the auxiliary mesh belt 6 and the printed substrate 5 before printing and the separation after printing, the following method is adopted: the first material roller 13 and the first mesh belt roller 11 are arranged in cooperation with each other relative to the first auxiliary wheel group 3, and the introduction position of the auxiliary mesh belt 6 on the first material roller 13 and the introduction position of the printed substrate 5 on the first mesh belt roller 11 are arranged on opposite sides relative to the first auxiliary wheel group 3; the second material roller 14 and the second mesh belt roller 12 are arranged in cooperation with each other relative to the second auxiliary wheel group 4, and the lead-out position of the auxiliary mesh belt 6 on the second material roller 14 and the lead-out position of the printed substrate 5 on the second mesh belt roller 12 are arranged on opposite sides relative to the second auxiliary wheel group 4.

[0035] In addition to the above basic functions, the present application can also be provided with an adsorption chamber 15 in the printing platform 1. Negative pressure is provided in the adsorption chamber 15 by a negative pressure fan. After the negative pressure is generated inside, the printing substrate 5 and the auxiliary mesh belt 6 under the printing substrate 5 can be set on the printing platform 1 through structures such as through holes on the adsorption chamber 15. It should be noted that during use, the auxiliary mesh belt 6 itself needs to be breathable to ensure stability after adsorption. On the other hand, a water cooling part is provided, and heat transfer of the printing substrate 5 is carried out through the water cooling part and the auxiliary mesh belt 6. Since the auxiliary mesh belt 6 itself can adopt a simplified structure with low thickness and good heat transfer and cooling performance, the cooling effect is guaranteed.

[0036] The printing platform 1 includes an adsorption chamber 15 , and a negative pressure fan is arranged at the lower part of the adsorption chamber 15 . The negative pressure fan is connected to the adsorption chamber 15 .

[0037] A water cooling part is also provided in the adsorption chamber 15, and the water cooling part is provided at the top of the adsorption chamber 15;

[0038] The water cooling part includes a water cooling pipe that is arranged in close contact with the adsorption chamber 15 , and the water cooling pipe is connected to a cold water supply tank through a cold water pump.

[0039] The mesh belt is a non-metallic breathable mesh belt, a mesh belt made of non-woven fabric or other materials.

[0040] The print head 2 includes a print slider, a plurality of print nozzles are arranged below the print slider, a drive screw is connected to the print slider, and a drive motor is arranged on one side of the drive screw.

[0041] When in use, the following steps are included:

[0042] Whether to use the auxiliary mesh belt 6 is determined according to the air permeability of the printing substrate 5;

[0043] If the printing substrate 5 itself is air permeable (the air permeability is not less than 10mm / s), of course the printing substrate 5 itself needs to have good tensile strength, such as high thickness or material properties, the auxiliary mesh belt 6 is moved out from the first auxiliary wheel group 3 and the second auxiliary wheel group 4; when the printing substrate 5 is air permeable, the printing substrate 5 is first passed between the first transmission roller and the first auxiliary roller 7, and then under the guidance of the first transmission roller, it is spray-printed through the printing platform 1, and then guided by the second transmission roller, it enters between the second transmission roller and the second auxiliary roller 10 to complete the printing.

[0044] Then the printing substrate 5 passes through the first transmission roller and the second transmission roller and the printing platform 1 therebetween, and then is spray-printed by the print head 2;

[0045] If the printing substrate 5 itself is not air permeable (air permeability is less than 10mm / s), especially suitable for flexible materials, the auxiliary mesh belt 6 is passed between the first transmission roller 8 and the first auxiliary roller 7, and then compounded with the printing substrate 5 on the outer side of the first transmission roller relative to the printing platform 1, and then enters the printing platform 1, and enters the second transmission roller after printing by the print head; at this time, the printing platform 1 can improve the effect of inkjet printing by turning on negative pressure adsorption and water cooling. Since the auxiliary mesh belt 6 of the present application does not have to bear the transmission, it is thin and can ensure a good water cooling effect.

[0046] On the outer side of the second transmission roller relative to the printing platform 1, the auxiliary mesh belt 6 and the printing substrate 5 are separated, and the auxiliary mesh belt 6 passes between the second transmission roller 9 and the second auxiliary roller 10 and then leads out of the second auxiliary wheel group 4, while the printing substrate 5 is directly led out of the second auxiliary wheel group 4 after separation.

[0047] When used, the above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
