In order to better illustrate the embodiment, some components in the drawings may be omitted, enlarged or reduced, which does not represent the actual product size. Those skilled in the art will understand that some well-known structures and illustration therefor may be omitted in the drawings. The terms for describing positional relationship in the drawings are for exemplary illustration only and are not to be construed as limiting this patent. The present utility model will be further illustrated in detail below in conjunction with particular embodiments.

Embodiment 1

(9) As shown in FIG. 1, a printer mechanism having multiple hosts on a common platform comprises a conveying platform 100 for conveying a printing substrate, an inkjet system 200 composed of eight relatively independent hosts 210 connected to each other, and a spray carriage system 300 composed of eight relatively independent spray carriages 310 installed with a spray nozzle module and connected to each other, the host 210 comprising at least a main cabinet 211 and an upper cabinet 212 extending from a side of the main cabinet 211, the upper cabinets 212 of the whole inkjet system 200 being distributed in parallel above the conveying platform 100, the spray carriage system 300 being disposed between the inkjet system 200 and the conveying platform 100, and the spray carriages 310 being correspondingly connected to the hosts 210 one by one.

(10) According to this embodiment, spray nozzles are separated from the hosts 210, and all the spray nozzles are combined to form the spray carriage system 300, achieving the integral installation of the spray nozzles, and the height of all of the spray nozzles can be easily controlled so as to achieve a uniform distance between each of the spray nozzles and the printing substrate, thus saving on time for installation and distance adjustment. Since both the spray carriage system 300 and the inkjet system 200 can be assembled in a modular manner, a user can purchase the same number of spray carriages 310 and hosts 210 according to actual needs, and it only needs to additionally purchase the same model of spray carriages 310 and hosts 210 for extension in the late and connect same to the spray carriages 310 and hosts 210 purchased in the early so as to complete the extension of the printer, so that the user does not need to be entangled in the contradiction between the limited initial investment funds and the later production extension demand. When the precision requirement is reduced, reduction printing can be realized by shielding the excess modules or by removing excess hosts 210 and spray carriages 310 according to different printing needs, thereby realizing free assembly and extension of the printer, reducing the assembly difficulty and saving on the assembly time. At the same time, when a single host 210 fails, the failed host 210 can be replaced to continue printing, avoiding delaying the production schedule due to repair, and replacement or maintenance for the hosts can be carried out one by one during machine maintenance so as to ensure continuous work during the machine maintenance.

(11) The printing substrate of different materials has different requirements on the distance between the spray nozzle and the surface of the printing substrate, and the distance between the spray nozzle and the surface of the printing substrate will also change due to the printing substrates different in thickness, so it is necessary to readjust the height of the spray nozzle every time replacing the printing substrates of different batches, and in order to conveniently adjust the height of the spray nozzle, the spray carriage system 300 is provided with a lifting mechanism for easy adjustment, specifically: as shown in FIG. 2, the spray carriage system 300 comprises a support base 320 and eight spray carriages 310, the spray carriage 310 is provided with a lifting frame 311, eight installation sites arranged in parallel are disposed at a front face of the support base 320, the lifting frames 311 are correspondingly installed to the installation sites one by one, each of the installation sites is provided with a screw rod 321, the screw rod 321 supports the lifting frame 311, and a transmission link 322 for transmission of a synchronous action is disposed between the screw rods 321. The driving mechanism, such as an electric motor, drives a screw rod 321 or the transmission mechanism to rotate, and when the screw rod 321 rotates, the other screw rods 321 are driven by the transmission link 322 to synchronously rotate, or the eight screw rods 321 are driven to synchronously rotate when the transmission link 322 rotates, thereby achieving simultaneous height adjustment for the spray nozzles of multiple spray carriages 310, which is convenient for operation and shortens the production cycle.

(12) Because the spray nozzle is relatively fragile and it determines the printing effect and quality, in order to protect the spray nozzle and avoid damage to the spray nozzle during storage or transportation, the spray nozzle usually needs to be packaged and stored separately and installed in the final step of the assembly. For the installation and disassembly of the spray nozzle, the spray carriage 310 is provided with several trays 312 for installation of the spray nozzle module, the trays are arranged in parallel on the lifting frame 311, and during installation, the spray nozzles are installed one by one in the installation holes of the trays, which is simple for operation and reliable for installation.

(13) In order to improve the stability of the printer mechanism, the conveying platform 100 comprises a conveyor belt 110, a power mechanism that drives the conveyor belt 110 for transport, and support portions 120 disposed at both ends of the conveyor belt 110, the support portions 120 support the conveyor belt 110, and at least a receiving space is formed below the conveyor belt 110. The conveying platform 100 is relatively independent, and the conveyor belt 110 is independently fixed and supported by the support portions 120, which will not interfere with addition or reduction or replacement of the hosts 210. When the production line is assembled, the support portions can be fixedly connected to the ground, so as to determine the position of the conveying platform 100 and avoid affecting the effect and precision of the inkjet due to the displacement of the conveying platform 100 caused by an external force, which ensures the stability of production.

(14) As shown in FIG. 3, in order to improve the flexibility of addition or reduction or replacement of the hosts 210, a side opening is formed at a front face of the hosts 210, the side opening is located between the upper cabinet 212 and the main cabinet 211, and part of the conveying platform 100 is suspended in the side opening. Viewed from the side, the host 210 is of a C-shape, so that any one host 210 can be quickly pull out of or push in from a side of the conveyor belt 110, and the host 210 will not be in contact with the conveyor belt 110 during the movement, thereby further improving the maintenance efficiency of the equipment.

(15) During use, in order to fix the relatively independent hosts 210 to each other, both sides of the hosts 210 are provided with positioning mechanisms connected to the adjacent hosts 210, and multiple hosts 210 are connected together by the positioning mechanisms to form an inkjet system 200 so as to avoid affecting the effect and precision of the inkjet due to the relative movement between the hosts 210 caused by an external force.

(16) In order to enable the hosts 210 to work independently without interference with each other, the host 210 is internally installed with an independent ink spray system, a control system, an ink supply system that supplies ink to the ink spray system, and a temperature control system that controls the inkjet temperature of ink from the ink spray system, the ink spray system is disposed in the upper cabinet 212, and the ink spray systems of the hosts 210 are correspondingly connected to the spray nozzle modules on the spray carriages 310 one by one.
