Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, specifically to a printing device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard boxes, as an important component of modern logistics and packaging, are widely used in various industries such as home appliances, machinery, electronics, food, and pharmaceuticals due to their low cost, light weight, high compressive strength, ease of printing, and recyclability. With the booming development of e-commerce and consumers' increasing demands for packaging quality, corrugated cardboard boxes have not only fulfilled their basic function of protecting goods but have also gradually evolved into an important medium for brand promotion and product display. Therefore, higher requirements are placed on the printing quality and efficiency of corrugated cardboard boxes.

[0003] However, in practical applications, traditional corrugated cardboard printing methods, such as offset printing, flexographic printing, and gravure printing, while each having their advantages, often present numerous challenges when handling large-area printing. For example, while offset printing offers high print quality, it requires complex and costly equipment and demands a high degree of flatness in the cardboard. Flexographic printing, while highly adaptable, is prone to uneven printing and color deviations when handling large-area printing. Gravure printing, while producing vibrant colors and exquisite patterns, has high plate-making costs and limited adaptability to inks and cardboard.

[0004] This results in traditional corrugated cardboard box printing equipment having problems such as limited printing area, low production efficiency, and high labor intensity. Especially when dealing with large-area, high-precision, and complex pattern printing, multiple machines are often required to work together, which not only increases production costs but also reduces production efficiency.

[0008] Preferably, a control panel is fixedly mounted on the front side of the upper end of the support platform, and the lower end of the negative pressure chamber is conical.

[0009] Preferably, the negative pressure pipe is connected to an external vacuum control pump, and there are several adsorption holes, which are symmetrically distributed in sequence around the center of the positioning groove.

[0010] Preferably, the telescopic portion of the rear end of the first electric telescopic rod is rotatably connected to the lower end of the L-shaped swing arm via a pin, and there are two mounting slots, which are symmetrically distributed on the lower side of the front end of the L-shaped swing arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the corrugated cardboard box is placed at the bottom of the positioning groove, the external vacuum control pump is turned on. When the external vacuum control pump is turned on, the vacuum inside the negative pressure chamber is evacuated through the negative pressure pipe. When the vacuum inside the negative pressure chamber is evacuated, a negative pressure is generated inside the negative pressure chamber. When a negative pressure is generated inside the negative pressure chamber, the corrugated cardboard box inside the positioning groove is adsorbed through the adsorption hole, thereby facilitating the adsorption and positioning of the corrugated cardboard box to be printed.

[0016] This invention simultaneously activates the drive motor when the bottom of the printing squeegee contacts the top of the printing screen. When the drive motor is activated, it drives the first synchronous pulley to rotate. The rotation of the first synchronous pulley, in turn, drives the second synchronous pulley to rotate via a synchronous belt. The rotation of the second synchronous pulley, in turn, drives the transmission screw to rotate. The rotation of the transmission screw, through the screw nut, drives the moving frame to move linearly back and forth. This linear movement of the moving frame synchronously drives the printing squeegee to move linearly back and forth as well. As the printing squeegee moves linearly, the pressure from its bottom transfers ink through the printing screen to the top of the corrugated cardboard box, thus facilitating large-area printing on the entire corrugated cardboard box.

A first electric telescopic rod 8 is rotatably connected to the bottom of the support platform 1 via a pin. The telescopic part of the rear end of the first electric telescopic rod 8 is rotatably connected to the lower end of the L-shaped swing arm 7 via a pin. There are two mounting grooves 9 fixedly installed on the lower front side of the L-shaped swing arm 7, symmetrically distributed on the lower front side of the L-shaped swing arm 7. A printing screen plate 10 is detachably fixedly installed on the inner wall of the mounting groove 9. A drive motor 11 is fixedly installed on the rear side of the upper end of the arm 7. A first synchronous pulley 12 is fixedly installed on the transmission shaft of the front end of the drive motor 11. A second synchronous pulley 13 is connected to the outer end of the first synchronous pulley 12 via a synchronous belt. A transmission screw 14 is fixedly installed in the middle of the second synchronous pulley 13. The transmission screw 14 is rotatably connected to the middle of the upper end of the L-shaped swing arm 7 via a rotating shaft. A movable frame 15 is connected to the outer curved surface of the middle of the transmission screw 14 via a screw nut. A first limiting slide rod 16 is movably connected through and fitted on both sides of the movable frame 15. The first limiting slide rod 16 is fixedly installed. At the upper end of the L-shaped swing arm 7, the first limiting slide rod 16 limits the forward and backward linear movement of the movable frame 15. A U-shaped mounting platform 17 is fixedly installed at the bottom of the movable frame 15. Connecting pipes 18 are fixedly installed on the front and rear sides of the lower end of the U-shaped mounting platform 17, and ink nozzles 19 are fixedly connected to the bottom of the connecting pipes 18. There are several ink nozzles 19, which are symmetrically distributed around the bottom of the connecting pipes 18. The side opening of the connecting pipes 18 is connected to an external ink pipeline through a connecting hose. A second electric telescopic device is fixedly installed through the upper end of the U-shaped mounting platform 17. There are two electric telescopic rods 20, which are symmetrically distributed on the front and rear sides of the upper end of the U-shaped mounting platform 17.

The upper sides of the lifting frame 21 are fixedly installed with second limiting slide rods 22, and the upper end of the second limiting slide rods 22 is connected to the upper end of the U-shaped mounting platform 17 through and fits, so that the lifting frame 21 can be linearly moved and limited by the second limiting slide rods 22. The lower end of the lifting frame 21 is supported and fixedly installed with a printing scraper 23, and the lower end of the printing scraper 23 has beveled angles on the front and rear sides.

[0024] Working principle: In use, the corrugated cardboard box to be printed is placed at the bottom of the positioning groove 3. When the corrugated cardboard box is placed at the bottom of the positioning groove 3, the external vacuum control pump is turned on. When the external vacuum control pump is turned on, the vacuum chamber 4 is evacuated through the negative pressure pipe 5. When the vacuum chamber 4 is evacuated, a negative pressure is generated inside the negative pressure chamber 4. When a negative pressure is generated inside the negative pressure chamber 4, the corrugated cardboard box inside the positioning groove 3 is adsorbed through the adsorption hole 24, thereby facilitating the adsorption and positioning of the corrugated cardboard box to be printed.

[0025] When the corrugated carton is in a fixed position, the first electric telescopic rod 8 is extended by control. When the first electric telescopic rod 8 extends, it pushes the lower end of the L-shaped swing arm 7 to swing backward. When the lower end of the L-shaped swing arm 7 swings backward, it drives the upper end of the L-shaped swing arm 7 to swing downward. When the upper end of the L-shaped swing arm 7 swings downward to a horizontal position, it simultaneously drives the printing screen plate 10 to swing downward to the top of the corrugated carton. When the printing screen plate 10 swings downward to the top of the corrugated carton, the external ink pipe is opened by control. When the external ink pipe is opened, the ink to be printed is delivered to the inside of the connecting pipe 18. When the ink is delivered to the inside of the connecting pipe 18, the ink nozzle 19 is opened. When the ink nozzle 19 is opened, the ink inside the connecting pipe 18 is discharged to the top of the printing screen plate 10. When the ink is discharged to the top of the printing screen plate 10, the second electric telescopic rod 20 is extended by control. When the second electric telescopic rod 20 extends, it drives the lifting frame 21 to move downward in a straight line. When the lowering frame 21 moves downward in a straight line, it will drive the printing squeegee 23 to move downward in a straight line. When the printing squeegee 23 moves downward in a straight line, the bottom of the printing squeegee 23 will contact the upper end of the printing screen plate 10. When the bottom of the printing squeegee 23 contacts the upper end of the printing screen plate 10, the drive motor 11 will be turned on by control. When the drive motor 11 is turned on, it will drive the first synchronous wheel 12 to rotate. When the first synchronous wheel 12 rotates, it will drive the second synchronous wheel 13 to rotate through the synchronous belt. When the second synchronous wheel 13 rotates, it will drive the transmission screw 14 to rotate. When the transmission screw 14 rotates, it will drive the moving frame 15 to move back and forth in a straight line through the screw nut. When the moving frame 15 moves back and forth in a straight line, it will synchronously drive the printing squeegee 23 to move back and forth in a straight line. When the printing squeegee 23 moves back and forth in a straight line, the ink will be transferred to the upper end of the corrugated carton through the printing screen plate 10 by the squeezing of the bottom of the printing squeegee 23, thereby realizing the function of facilitating the overall large-area printing of the corrugated carton.
