Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a miniaturized direct-out printing machine for sheets. Background Art

[0002] For the packaging of fast-moving consumer goods such as food, there is an urgent need in the market for a box printer that can be used in small stores to meet the demand for rapid customization; the usage environments of store customers and traditional printing factories are vastly different.

[0003] Traditional factories have no high requirements for noise control, air quality control, etc. of printing equipment, but store customers have relatively high requirements. Therefore, it is necessary to upgrade the printing equipment to be green and harmless, including special optimization of parts such as noise control and dust removal and cleaning; store customers also have special requirements for the floor area of the equipment. Under the requirements of a paper feeding width of 1.3 meters and a printing width of 1.05 meters, the equipment volume should be reduced as much as possible. Store customers usually do not have full-time printing staff positions, and the demand for the ease of use and maintenance of the equipment is further increased. Summary of the Utility Model

[0004] In view of the problems existing in the above-mentioned existing printing machines, the present utility model is proposed.

[0005] Therefore, the purpose of the present utility model is to provide a miniaturized direct-out printing machine for sheets, which solves the above problems.

[0006] In order to achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A miniaturized direct-out printing machine for sheets, comprising a silent negative pressure system and a printing system. The printing system is arranged on one side of the silent negative pressure system. A nozzle carriage is arranged inside the printing system. A nozzle maintenance station is arranged on the front side of the nozzle carriage. A secondary ink supply system is arranged on one side of the nozzle carriage. A primary large ink bucket is arranged below the secondary ink supply system. An air suction paper feeding system is arranged on the front side of the nozzle maintenance station. A nozzle carriage lifting module is arranged on the side of the nozzle carriage away from the secondary ink supply system;

[0008] A blower air inlet is arranged at the top of the silent negative pressure system. A blower air outlet is arranged at the bottom of the silent negative pressure system. A dust removal filter element is arranged in the middle of the silent negative pressure system. A blower exhaust air box is arranged at the inner bottom end of the silent negative pressure system.

[0009] Preferably, a plurality of nozzles are arranged on the front side inside the nozzle carriage. A filter, a solenoid valve for nozzle ink circulation, and a peristaltic pump for nozzle ink circulation are sequentially arranged from left to right at the rear side inside the nozzle carriage. A paper pressing wheel and an ion wind static eliminator bar are arranged below the nozzle carriage. A dust removal and cleaning suction nozzle is arranged on one side of the paper pressing wheel.

[0010] Preferably, a diaphragm pump for positive pressure cleaning, a three-way solenoid valve for positive pressure / atmosphere switching, a peristaltic pump for supplying ink from the first-level ink bucket to the second-level ink bottle, and a solenoid valve for controlling the on / off of ink supply are sequentially arranged from top to bottom inside the secondary ink supply system.

[0011] Preferably, a blower cooling exhaust vent is provided on one side above the silent negative pressure system, and a blower cooling air inlet is provided on the other side.

[0012] Preferably, noise reduction sponges are arranged inside both the blower cooling exhaust vent and the blower cooling air inlet.

[0013] Preferably, an ink filter is arranged at one end of the peristaltic pump for supplying ink from the first-level ink bucket to the second-level ink bottle.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0015] 1. In the present utility model, through the design of a five-nozzle wide-format inkjet vehicle, the inkjet width reaches 1050 mm, meeting the printing requirements of customized packaging boxes for stores.

[0016] 2. In the present utility model, before cardboard printing, the cardboard first passes through brush cleaning, then through static elimination treatment, and finally through a high negative pressure (-30 to 50 Kpa) dust suction nozzle, which can filter more than 70% of the dust and shredded paper on the cardboard surface, basically meeting the cleaning requirements of non-direct contact food outer packaging.

[0017] 3. In the present utility model, through the punched conveyor belt made of a rubber coating process, the hardness of the rubber layer is about 45 degrees on the Shore scale, greatly improving the friction coefficient between the cardboard and the conveyor belt. Coupled with the negative pressure provided by the belt holes, there is no slipping phenomenon during the printing and conveying process of the cardboard, ensuring the printing quality.

[0018] 4. In the present utility model, through the secondary circulation ink supply system, during the printing interval, the ink in the ink chamber of the nozzle is ensured to circulate and flow, taking away the microbubbles inside the nozzle and preventing the nozzle holes from being blocked by air.

[0019] 5. In the present utility model, through the longitudinally arranged wide-format nozzle maintenance station, while ensuring easy maintenance, the lateral volume of the wide-format printing equipment is greatly reduced.

[0020] 6. In the present utility model, through the silent negative pressure system, three high-pressure vortex air pumps are used to provide a negative pressure of -30 to 50 Kpa, respectively providing pressure for cardboard dust removal and the paper conveying belt. To meet the silent requirement of the equipment exhaust system, the entire system box is enclosed and soundproofed. To prevent the wind force at the air outlet from being too large and causing dust dispersion, the air pump pipeline is connected to a dust removal filter element, and at the same time, each exhaust vent passes through an exhaust box to reduce the speed and pressure, slowing down the air outlet flow rate to achieve qualified emissions.

[0021] 7. In this utility model, the nozzle carriage rises and returns to the origin position, the moisturizing base plate retracts to directly below the nozzle carriage, aligning the moisturizing ink pad with the nozzle. The nozzle carriage descends and closely adheres to the surface of the nozzle. At this time, the peristaltic pump squeezes the ink chamber of the nozzle, and the ink in the chamber is used to flush the nozzle holes. After the flushing is completed, the nozzle carriage rises, and the surface of the nozzle is manually wiped with a wiping paper. After the wiping is completed, the nozzle carriage descends, and the sealing ring of the moisturizing ink pad contacts the surface of the nozzle, covering the nozzle hole area to achieve the purpose of moisturizing the nozzle.
