Description

Technical Field

[0001] The invention belongs to the technical field of rotary inkjet printers, in particular to a double-sided coating device for a rotary inkjet printer. Background Art

[0002] The rotary inkjet printer is a commonly used high-efficiency printer that uses a double-sided coating device for double-sided printing. Before operation, a large amount of ink needs to be added to the drum. If color content needs to be printed, color ink needs to be added to the drum. The drum rotates continuously, and all the ink will be printed on the paper, so that the rotary printer can complete the printing task.

[0003] Chinese Patent: CN220146951U A double-sided coating device for a rotary inkjet printer, which can absorb the ink in the oil filling tank and evenly apply it on the printing cylinder by setting oil-absorbing cotton and oil-absorbing rod, replacing the original oil-outlet printing method, which can avoid blockage of the oil outlet hole and leakage;

[0004] In the above patent, since most of the products used by rotary inkjet printers are paper or cloth, when used on cloths of different materials, if the effect of the cloth is poor, when the coating roller contacts the paper or cloth, the exposed silk material on the surface of the paper or cloth will be partially attached to the coating roller by the ink, and when the coating roller moves to the ink absorption position, it will affect the nozzle or the oil absorption position, which will eventually lead to poor effect in subsequent coating.

[0005] In view of this, a double-sided coating device for a rotary inkjet printer is proposed. Utility Model Content

[0006] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0007] In view of the following technical problems in the prior art: since most of the products used by rotary inkjet printers are paper or cloth, when faced with cloth of different materials, when the cloth effect is poor, when the coating roller comes into contact with the paper or cloth, the exposed silk material on the surface of the paper or cloth will be partially adhered to the coating roller by the ink. When the coating roller moves to the ink absorption position, it will affect the nozzle or the oil absorption position, ultimately resulting in poor effect during subsequent coating.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: a double-sided coating device of a rotary inkjet printer, comprising a support frame, a coating roller and a collecting box;

[0009] The coating roller is rotatably connected to the inner edge of the support frame, and the two ends of the coating roller are docked with the support frame through a transmission roller 1. The collection box is docked and installed on the inner edge of the bottom end of the support frame, and the lower end of the coating roller is located in the collection box;

[0010] The support frame is provided with a through hole 1 on its surface, a rotating seat is rotatably connected to the through hole 1, a through hole 2 is provided in the rotating seat, a limiting groove is provided on the inner edge of the through hole 2, and the limiting grooves are distributed at equal angles with respect to the axis of the rotating seat;

[0011] A bearing seat is connected to the second through hole, a wire mesh frame is arranged between the two bearing seats, wherein the wire mesh frame is used to clean the wire on the surface of the coating roller, and a second transmission roller is arranged on the side of the bearing seat away from the wire mesh frame, wherein the second transmission roller and the first transmission roller can be driven by a belt;

[0012] A coating roller and a recovery roller are arranged inside the collection box. The coating roller contacts the surface of the coating roller and can evenly apply ink to the surface of the coating roller. The recovery roller does not directly contact the coating roller and maintains a certain distance from it, so that it can absorb excess ink.

[0013] As a preferred technical solution for a double-sided coating device of a rotary inkjet printer, a threaded hole is provided in the second drive roller, a threaded rod is threadedly transmitted in the threaded hole, and one end of the threaded rod is rotatably connected to a spline shaft.

[0014] As a preferred technical solution for a double-sided coating device of a rotary inkjet printer, an operating chamber is provided inside the bearing seat, a rotating shaft is rotatably connected in the operating chamber, a guide seat is provided on one side of the rotating shaft, and a spline groove is provided on the guide seat for cooperating with the spline shaft. When the threaded rod is rotated, the rotating shaft can be controlled to rotate under the threaded transmission action of the threaded rod and the threaded hole, and in conjunction with the sliding connection relationship between the spline shaft and the guide seat, and under the action of the thread, it can also achieve a self-locking effect.

[0015] As an optimal technical solution for a double-sided coating device of a rotary inkjet printer, the outer periphery of the rotating shaft is rotatably connected to a connecting rod, and the end of the connecting rod away from the rotating shaft is rotatably connected to a clamping block. The clamping block moves in a directional manner along the inner edge of the operating cavity, and can be extended and retracted through the connecting rod to link the clamping block when the rotating shaft rotates. When the clamping block is docked in the limit groove, the bearing seat and the bearing seat can be positioned and installed.

[0016] As a preferred technical solution for a double-sided coating device of a rotary inkjet printer, a sharp tooth frame is provided inside the wire mesh frame, and the sharp tooth frame can be used to conveniently collect and clean the wires and the like wound on the wire mesh frame after the entire frame is disassembled.

[0017] As a preferred technical solution for a double-sided coating device of a rotary inkjet printer, a suction pad is provided on the upper surface of the recovery roller, wherein the suction pad is used to absorb excess ink on the coating roller, and a material guide seat is provided under the recovery roller. The recovery roller is a hollow structure. When the suction pad absorbs excess ink, the ink will fall into the recovery roller due to gravity and reach the collection box through the material guide seat, thereby achieving the utilization effect.

[0018] Beneficial effects of the present invention:

[0019] 1. The double-sided coating device enables the wire mesh frame and the coating roller to move synchronously through the interaction of the rotating seat, the second transmission roller and the first transmission roller. The wire mesh frame can be used to wind and collect the wire material on the surface of the coating roller, thereby improving the coating effect of the coating roller on the cloth;

[0020] 2. When the double-sided coating device is installed, the bearing seat is inserted into the appropriate position in the second through hole, and the threaded rod is rotated. Under the action of the threaded transmission, the spline shaft and the guide seat, the rotating shaft can be rotated. Under the action of the connecting rod, the card block can be inserted into the limit groove accordingly. At this time, the bearing seat and the wire mesh frame can be quickly installed, thereby improving the installation and maintenance efficiency of the wire mesh frame and the bearing seat;

[0021] 3. The double-sided coating device uses the coating roller to evenly coat the coating roller with ink. Under the action of the suction pad, it can prevent excessive ink from being coated on the cloth, and under the action of the recovery roller and the guide seat, the excess ink can be recycled.

[0022] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and the drawings.
