Description

Technical Field

[0001] The utility model relates to the technical field of food printing, in particular to a multi-nozzle integrated printing device. Background Art

[0002] Most existing food printing equipment uses a single conveyor belt production line to print on the food surface. Even if there are multiple print heads, because the multiple print heads share the same ink path and sensor, they can only print on the same food surface at the same time.

[0003] When printing food in multiple channels, after the infrared sensor recognizes the food, the nozzle will print on the surface of the food, but multiple nozzles will spray ink at the same time. In this case, if a column of food is rejected due to defects, the ink from the nozzle will be sprayed onto the conveyor belt and contaminate the food on the subsequent conveyor belt, affecting the effect of food printing.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] like Figure 1-Figure 4 As shown, in one embodiment, a multi-nozzle 7 integrated printing device is arranged above a conveyor belt (not shown in the figure). The width of the printing device is greater than the width of the conveyor belt so that the printing device can span above the conveyor belt. Specifically, the printing device includes a profile bracket 1, a lifting bracket 2 is provided in the hollow interior of the profile bracket 1, a printer head 3 is slidably connected to one side of the lifting bracket 2, and a multi-channel printing unit is provided inside the printer head 3. A plurality of sensors 4 for sensing objects are provided on the outside of the profile bracket 1, and each sensor 4 is electrically connected to the corresponding printing unit in the printer head 3. After sensing the food on the conveyor belt, the sensor 4 controls the nozzle 7 in the corresponding printing unit to spray the food.

[0028] Optionally, each printing unit includes a secondary ink tank 5, a solenoid valve 6 and a nozzle 7. The secondary ink tank 5 is connected to the solenoid valve 6 and the nozzle 7 through a pipeline (not shown in the figure). Specifically, the sensor 4 is electrically connected to the solenoid valve 6 and the nozzle 7. When the sensor 4 senses the food on the conveyor belt, the solenoid valve 6 and the nozzle 7 are controlled to open, thereby realizing spray printing.

[0029] Optionally, multiple boards 8 are further disposed within the printer head 3, each board 8 being electrically connected to each solenoid valve 6 and nozzle 7. After the sensor 4 senses the food below, the board 8 receives a signal from the sensor 4 and controls the solenoid valve 6 and nozzle 7 to open, thereby achieving printing. It should be noted that the specific connection between the sensor 4, the solenoid valve 6, the nozzle 7, and the board 8, as well as the specific control method of the board 8, are mature existing technologies and will not be further described here.

[0030] Optionally, fans 9 are provided on both sides of the board 8, and the fans 9 are used to dissipate heat for the board 8. The fans 9 are connected to the power supply. After the fans 9 are started, the fans 9 on both sides perform convection, which can dissipate heat for multiple boards 8 arranged in the middle, ensuring that the boards 8 can be used under normal temperature conditions.

[0031] Optionally, a safety bottle 10 is provided in the printer head 3, and the safety bottle 10 is provided between the secondary ink tank 5 and the air circuit assembly (not shown in the figure), wherein the air circuit assembly is a device that generates negative pressure. When the liquid level of the secondary ink tank 5 shakes or there are too many bubbles, the ink will be sucked into the air circuit assembly, causing pollution of the air circuit and damage to the circuit. The present application sets the safety bottle 10, which can prevent back suction and protect the air circuit assembly.

[0032] Optionally, in some embodiments, the sensor 4 may be an infrared sensor 4 or other sensors 4 , and the specific selection may be based on actual needs.

[0033] Optionally, the lifting bracket 2 includes a lifting cylinder 21 , one side of the lifting cylinder 21 is slidably connected to a slider 22 , and the slider 22 is connected to the printer head 3 . The lifting cylinder 21 can drive the printer head 3 to move up and down.

[0034] Optionally, a degassing column (not shown) is provided between the secondary ink reservoir 5 and the printhead 7. This column is used to remove dissolved gases from the ink in the inkjet printing system. The degassing column is a hollow fiber membrane separation component that effectively removes dissolved gases from the ink in the inkjet printing system. Specifically, the degassing column includes an outlet, an inlet, and two vacuum ports.

[0035] Optionally, a butterfly filter (not shown) is provided between the front end of the nozzle 7 and the rear end of the degassing die. The butterfly filter is used to filter impurities from the ink. Specifically, when ink containing impurities enters the butterfly filter through the pipeline, the ink first contacts the outer surface of the filter element under the action of pressure. As the fluid passes through the filter element, the impurities are intercepted by the filter element. The filtered clean ink then passes through the internal channel of the filter element and converges at the filter outlet. It then flows out of the filter and enters the nozzle 7.

[0036] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0037] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
