Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a printing device based on UV color-white and black-white color bidirectional printing technology. Background Art

[0002] UV color, white, black and white is a UV process, which belongs to a kind of UV inkjet printing. It has bright and rich colors, is wear-resistant and UV-resistant. Color, white, black and white uses the combination of transparent materials and white ink printing capabilities to print out various excellent pictures. Bidirectional printing is also called bi-directional printing, which refers to the ability of the printing equipment to do a reverse, that is, to cooperate with the sensor to transmit the detected printing working status, paper congestion and other information to the computer to keep the printing process controllable and monitorable.

[0003] Existing bidirectional printing devices are mostly used in printers. The printing components with UV inkjet printing technology adopt layered printing to achieve one-time white and color inkjet printing, such as transparent film, transparent film, PVC film, etc. When printing such materials, because the surface of the material is relatively smooth, the friction of the printer is insufficient, and the material positioning is prone to unstable during the printing process, which affects the printing working state and efficiency and reduces the printing quality. For this reason, we propose a printing device based on UV color white, black and white color bidirectional printing technology. Utility Model Content

[0007] Furthermore, the ventilation holes are evenly opened around the inside of the printing board, and the bottom end of the printing board and the ventilation pipe are communicated with each other.

[0008] Furthermore, the ventilation duct and the fan are distributed along the bottom of both ends of the outer frame, and the ventilation duct and the fan are connected.

[0009] Furthermore, the machine includes a frame, and a cushion layer is arranged around the bottom end of the frame, a printing table is arranged on the top surface of the frame, printing guide rails are arranged on the inner walls on both sides of the printing table, and pressure rollers are arranged at both ends of the printing table.

[0010] Furthermore, the stand is fixedly connected to the printing table and the cushion layer, and both ends of the printing table are rotatably connected to the pressure roller.

[0011] Furthermore, the printing guide rail includes a transverse rail frame, screws are distributed at both ends of the transverse rail frame, and the bottom ends of the screws are connected to the printing table, one side of the transverse rail frame is connected to a longitudinal rail frame, and a printing module is arranged at the middle end of the longitudinal rail frame.

[0012] Furthermore, the transverse rail is connected to the printing table via screws, and the printing module is slidably matched with the transverse rail via the longitudinal rail.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When printing on materials such as transparent PVC, the printing device can assist in adsorption by aligning the material with the printing plate on the bottom of the material. Through computer control, the pressure roller does not adsorb when it is driving. During the printing process, the exhaust pipes and fans at both ends assist in adsorption positioning, thereby providing a stable position of the material during the printing process, reducing the deviation phenomenon, and improving the printing quality and efficiency.

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] The utility model provides Figure 1-4 A printing device based on UV color-white and black-white bidirectional printing technology is shown, comprising a table machine 1, a printing guide rail 2 is arranged on the top surface of the table machine 1, and a suction positioning mechanism 3 is arranged inside the table machine 1, the table machine 1 comprises a stand 101, and a cushion layer 102 is arranged at the bottom end of the stand 101, a printing table 103 is arranged at the top end of the stand 101, printing guide rails 2 are arranged on the inner walls of both sides of the printing table 103, and pressure rollers 104 are arranged at both ends of the printing table 103;

[0028] In order to maintain the stability of the printing process, such as Figure 1As shown, this printing device uses a stand 101 and a rubber pad 102 at the bottom as a base to provide stable support, and the top is equipped with a printing table 103 to carry a printing guide rail 2, thereby cooperating with pressure rollers 104 at both ends to position the material and assist in completing a stable printing process.

[0029] like Figure 1-2 As shown, the printing guide rail 2 includes a transverse rail frame 201, screws 202 are distributed at both ends of the transverse rail frame 201, and the bottom end of the screw 202 is connected to the printing table 103, one side of the transverse rail frame 201 is connected to a longitudinal rail frame 203, and a printing module 204 is arranged at the middle end of the longitudinal rail frame 203;

[0030] In order to facilitate the maintenance and repair of this printing device, Figure 1-2 As shown, the printing module 204 of the printing device is connected to both sides of the printing table 103 through the longitudinal rail frame 203 and the transverse rail frame 201, and the transverse rail frame 201 is fixed with screws 202, so the disassembly and separation process is convenient.

[0031] like Figure 3-4 As shown, the air suction positioning mechanism 3 includes an outer frame 301, and exhaust pipes 302 are arranged at both ends of the outer frame 301, one end of the exhaust pipe 302 is connected to a fan 303, and the other end of the fan 303 is connected to a ventilation pipe 304, the top end of the ventilation pipe 304 is connected to a printed board 305, and ventilation holes 306 are opened around the top surface of the printed board 305;

[0032] Finally, in order to keep the material positioning of this printing device stable during the printing process, such as Figure 3-4 As shown, when this printing device prints materials such as transparent PVC, the printing plate 305 on the bottom of the material can be used to align the attached material for adsorption assistance.
