Description

Technical Field

[0001] The utility model relates to the field of printing equipment, in particular to an environment-friendly UV ink oil supply and oil control structure for laser transfer printing. Background Art

[0002] In cigarette label printing, in order to achieve the sense of hierarchy of laser, environment-friendly UV ink is generally used for printing (it is polluting, which is likely to affect the taste and is harmful). However, in the existing ink oil supply and oil control, two valves are generally used for control. Therefore, the control accuracy and the accuracy of the controlled quantity are relatively low. At the same time, its structure is relatively complex and the volume is relatively large.

[0003] Among them, the metering requirements of UV ink are relatively precise. Too much may lead to too high reflectivity of laser, resulting in a decrease in the sense of hierarchy; too little UV ink may lead to a decrease in the printing and adhering effect of the product, affecting its weather resistance. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an environment-friendly UV ink oil supply and oil control structure for laser transfer printing, aiming to improve the existing oil supply and oil control structure, and further realize the UV ink.

[0005] To achieve the above purpose, the utility model provides an environment-friendly UV ink oil supply and oil control structure for laser transfer printing, including:

[0006] A raw material tank;

[0007] A control device, the control device includes a hollow cylinder body, a rotary servo motor arranged at the upper end of the cylinder body, a connecting piece extending into the cylinder body, and a conveying roller. The cylinder body is provided with a feeding port at the position of the connecting piece.

[0008] The upper end of the connecting piece is connected to the driving end of the rotary servo motor, and the upper end of the conveying roller is connected to the lower end of the connecting piece.

[0009] The rotary servo motor drives the conveying roller to rotate through the connecting piece;

[0010] The lower end of the cylinder body is provided with a discharge port, the discharge port deviates from the axis position of the cylinder body, the outer peripheral wall of the conveying roller is provided with a protruding spiral part, the lower end of the conveying roller has an inclined surface part, and the spiral part extends to the inclined surface part.

[0011] The inclined surface part can rotate between a position tangent to the discharge port and a position away from the discharge port.

[0012] In actual design, driving the conveying roller to rotate through the connecting piece can avoid the eccentric force caused by the unevenness of the spiral part, and then ensure the tangency (i.e., sealing) between the inclined surface part and the discharge port. Of course, when the spiral part rotates one circle, a certain amount of ink is conveyed to the position of the discharge port (which can be understood as a section of spiral quantity). That is, when the inclined surface part is far away from the discharge port, the ink enters the discharge port, thereby ensuring the precise oil supply (realized by the screw) and oil control (determined by the inclined surface part and the discharge port) of the ink; the ink quantity is precisely controlled, and the structure is simple and stable.

[0029] As Figures 1 to 4 shown, an environment-friendly UV ink oil supply and oil control structure for laser transfer printing includes:

[0030] A raw material tank 1;

[0031] A control device 2, the control device 2 includes a hollow cylinder 20, a rotary servo motor 21 provided at the upper end of the cylinder 20, a connecting member 3 extending into the cylinder 20, and a conveying roller 22. The cylinder 20 is provided with a feeding port 51 at the position of the connecting member 3.

[0032] The upper end of the connecting member 3 is connected to the driving end of the rotary servo motor 21, and the upper end of the conveying roller 22 is connected to the lower end of the connecting member 3.

[0033] The rotary servo motor 21 drives the conveying roller 22 to rotate through the connecting member 3.

[0034] The lower end of the cylinder 20 is provided with a discharge port 52, the discharge port 52 is connected to the raw material tank, the discharge port 52 is deviated from the axis position of the cylinder 20, the outer peripheral wall of the conveying roller 22 is provided with a protruding spiral portion 4, the lower end of the conveying roller 22 has an inclined surface portion 41, and the spiral portion 4 extends to the inclined surface portion 41.

[0035] The inclined surface portion 41 can rotate between a position tangent to the discharge port 52 and a position away from the discharge port 52.

[0036] In the actual design, driving the conveying roller 22 to rotate through the connecting member 3 can avoid the eccentric force caused by the unevenness of the spiral part 4, thereby ensuring the tangency (i.e., sealing) between the inclined surface part 41 and the discharge port. Of course, when the spiral part 4 rotates one circle, a certain amount of ink is conveyed to the position of the discharge port (which can be understood as a certain spiral amount). That is, when the inclined surface part 41 is far away from the discharge port, the ink enters the discharge port, thereby ensuring the precise oil supply (realized by the screw) and oil control (determined by the inclined surface part 41 and the discharge port) of the ink; the ink volume is precisely controlled, and the structure is simple and stable.

[0037] Specifically, the connecting member 3 is a universal shaft, so that the conveying roller 22 has a certain offset, so that the ink flows out precisely from the discharge port.

[0038] Further, the universal shaft includes an H-shaped member 30, a first pivoting part 31 and a second pivoting part 32 provided at the upper and lower ends of the H-shaped member 30. The first pivoting part 31 is pivotally connected to the driving end of the rotary servo motor 21, and the upper end of the conveying roller 22 is pivotally connected to the second pivoting part 32, thereby realizing a predetermined angle of offset.

[0039] Specifically, the cylinder body 20 is provided with a reduced-diameter part 6 at the upper end of the conveying roller 22. The inner diameter of the reduced-diameter part 6 is similar to the outer diameter of the spiral part 4, thereby controlling the flow rate of the feed port.

[0040] Further, the cylinder body 20 is provided with a sealing plug 8. The driving end of the rotary servo motor 21 passes through the through hole 81 of the sealing plug. Through the setting of the sealing plug, a sealing structure inside the cylinder body 20 is realized, reducing the oxidation of the ink.

[0041] Further, a display control screen 7 is provided on one side of the cylinder body 20. The display control screen 7 is used to display the discharge flow rate of the discharge port and the rotation speed or number of turns of the rotary servo motor 21. By controlling the rotation speed of the rotary servo motor 21, the output of the flow rate is controlled. When the viscosity of the ink is different, by manually weighing the predetermined number of turns and rotation speed, the precise addition amount can be obtained.

[0042] Specifically, one side of the inclined surface part 41 is a diversion surface 42, that is, the inclined surface part 41 blocks the discharge port, and the diversion surface 42 conveys the fluid.

[0043] Further, the discharge port includes a vertical channel 521 and a reduced-diameter channel 522, thereby ensuring the predetermined flow rate of the ink output.

[0044] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
