Description

Technical Field

[0001] This utility model belongs to the technical field of packaging box printing equipment, specifically a green inkjet printing device for pharmaceutical packaging. Background Technology

[0002] A search revealed a green printing device for the surface of a pharmaceutical packaging box, disclosed in patent application number 202323620459.5. The device includes two support blocks; conveyor belts are mounted on opposite sides of the two support blocks; printers are mounted on the upper surfaces of the two conveyor belts; grooves are formed on the upper surfaces of both conveyor belts; a fixing plate is mounted below the inner walls of the two grooves; a suction platform is mounted on the upper surface of the fixing plate; and limiting ports are formed on both the front and rear sides of the upper surface of the suction platform. This invention achieves pre-correction of the material before printing. By controlling the first motor within the rotating assembly to drive the bidirectional lead screws and connecting shafts on both sides to rotate together, the connecting blocks on both sides also move together. Simultaneously, the movement drives the clamping blocks within the clamping and correcting assembly to perform a corrective operation on the material. The buffer spring prevents potential damage to the material surface, enabling correction of materials of different widths and improving the production quality of the equipment.

[0003] Although the aforementioned patent achieves pre-printing material correction by controlling the first motor in the rotating assembly to drive the bidirectional lead screws and connecting shafts on both sides to rotate together, thereby moving the connecting blocks on both sides as well, and simultaneously driving the clamping blocks in the clamping and correction assembly to perform the material correction operation, and using the force of the buffer spring to prevent possible damage to the material surface, thus achieving correction for materials of different widths and improving the production quality of the equipment, in actual use, the correction mechanism needs to be activated to correct the material position only after the material has moved to the bottom of the printer. The correction mechanism needs to be reset before the next printing can proceed, which reduces printing efficiency.

[0004] Therefore, it needs to be modified so that the gap of the correction mechanism can be pre-adjusted according to the width of the material to be printed, and the material can be limited when it moves, so that the material is directly under the printer when printing, avoiding printing deviation. This allows for uninterrupted printing of the same batch of materials of the same specifications, improving printing efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a green inkjet printing pharmaceutical packaging printing device. This device has the advantages of pre-adjusting the gap of the correction mechanism according to the required printing material width, limiting the material movement, ensuring the material is directly below the printer during printing to avoid printing deviations, and enabling uninterrupted printing of the same batch of materials of the same specifications, thus improving printing efficiency. It solves the problem of needing to activate the correction mechanism to correct the material position only after it has moved below the printer, requiring the correction mechanism to reset before the next printing, which reduces printing efficiency.

[0006] This utility model provides the following technical solution: a green inkjet printing pharmaceutical packaging printing device, comprising a carrier plate, side support plates fixedly connected to the front and rear sides of the top of the carrier plate, and a conveyor belt mechanism fixedly connected to one side of the two side support plates opposite to each other. A top edge plate is fixedly connected to the top of the side support plates, and a printer body is fixedly connected to the center of the top of the top edge plate. The output end of the printer body is on the same plane as the center line of the conveyor belt mechanism. Square holes penetrating from front to back are opened on the left and right sides of the top of the two top edge plates, and first electric telescopic rods are fixedly connected to the left and right sides of the outer surfaces of the two top edge plates via support plates. The output end of an electric telescopic rod passes through a square hole and extends above the conveyor belt mechanism. A straightening push plate is fixedly connected to the output end of the first electric telescopic rod. A circular hole with a through-hole is opened on both the left and right sides of the straightening push plate, and a guide rod is slidably connected inside the circular hole. A push frame is fixedly connected to the inner end of the guide rod. A compression spring is sleeved on the surface of the guide rod. The inner end of the compression spring is fixedly connected to the outer side of the push frame. The outer end of the compression spring is fixedly connected to the inner side of the straightening push plate. A number of evenly distributed rollers are rolled inside the push frame, and the two sets of rollers are arranged symmetrically. The bottom of the push frame is higher than the top of the surface of the conveyor belt mechanism.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. This utility model involves placing the packaging box to be printed on top of a conveyor belt mechanism. The conveyor belt mechanism moves the packaging box to the right. Then, according to the specifications of the packaging box, the first electric telescopic rod is activated. The activation of the first electric telescopic rod causes two straightening push plates to move closer together. When the two straightening push plates move closer together, they also cause two sets of guide rods and push frames to move closer together until the surface of the rollers is in contact with the surface of the packaging box, pushing the packaging box to the center line of the conveyor belt mechanism. This ensures that the packaging box is aligned with the output end of the printer body when passing by the printer body. At this point, the extension of the first electric telescopic rod stops, fixing the position of the rollers. Subsequently, as the packaging box moves to the right via the conveyor belt mechanism, it moves back and forth... Both sides are in contact with the surface of the rollers, causing the rollers to roll and gather the packaging box to the center of the conveyor belt mechanism without affecting its movement. Simultaneously, through the coordinated arrangement of compression springs and guide rods, when the packaging box is tilted to one side, the rollers and push frame retract outwards, and then the springs push the packaging box towards the center, preventing it from being squeezed and damaged. This allows for pre-adjustment of the gap in the correction mechanism according to the required printing material width, limiting material movement and ensuring the material is directly below the printer during printing to avoid printing deviations. It also allows for uninterrupted printing of the same batch of materials of the same specifications, improving printing efficiency.

[0009] 2. This utility model uses a combination of a drying hood, a heating rod, and a blower to heat the air inside the drying hood and blow the hot air onto the printed packaging box. This dries the printing marks on the surface of the packaging box, accelerates the setting of the printing marks, prevents the printing marks from being scratched, and improves the printing effect.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 6 As shown, the green inkjet printing pharmaceutical packaging printing device of this embodiment includes a carrier plate 1. Side support plates 2 are fixedly connected to the front and rear sides of the top of the carrier plate 1. A conveyor belt mechanism 3 is fixedly connected to one side of each of the two side support plates 2 facing each other. A top edge plate 4 is fixedly connected to the top of the side support plates 2. A printer body 5 is fixedly connected to the center of the top of the top edge plate 4. The output end of the printer body 5 is on the same plane as the center line of the conveyor belt mechanism 3. Square holes penetrating from front to back are opened on the left and right sides of the top of each of the two top edge plates 4. First electric telescopic rods 6 are fixedly connected to the left and right sides of the outer surface of each of the two top edge plates 4 via support plates. The output end of the first electric telescopic rod 6 passes through the square hole and extends to the top of the conveyor belt mechanism 3. The output end of the first electric telescopic rod 6 is fixedly connected to the straightening push plate 7. The straightening push plate 7 has round holes that pass through from front to back on both the left and right sides. The guide rod 8 is slidably connected inside the round hole. The inner end of the guide rod 8 is fixedly connected to the push frame 9. The surface of the guide rod 8 is fitted with a compression spring 10. The inner end of the compression spring 10 is fixedly connected to the outer side of the push frame 9. The outer end of the compression spring 10 is fixedly connected to the inner side of the straightening push plate 7. The inside of the push frame 9 is connected with a number of evenly distributed rollers 11, and the two sets of rollers 11 are symmetrically arranged. The bottom of the push frame 9 is higher than the top of the surface of the conveyor belt mechanism 3.

[0018] refer to Figure 4 A drying hood 12 is fixedly connected to the right side of the top edge plate 4. A heating rod 13 is fixedly connected to the lower part of the inside of the drying hood 12. Several evenly distributed blowers 14 are fixedly connected to the upper part of the inside of the drying hood 12. The output end of the blower 14 faces downward and the wind force of the blower 14 is 2-3m / s.

[0019] This embodiment uses a combination of a drying hood 12, a heating rod 13, and a blower 14. The heating rod 13 heats the air inside the drying hood 12, and the blower 14 blows the hot air onto the printed packaging box to dry the printing marks on the surface of the packaging box, accelerate the setting of the printing marks, avoid scratching the printing marks, and improve the printing effect.

[0020] refer to Figure 1 The top of the drying hood 12 is provided with an air inlet groove 15, and a dust filter plate 16 located above the air inlet groove 15 is fixedly connected to the top of the drying hood 12 by bolts.

[0021] This embodiment increases the air intake volume when the blower 14 is started by setting the air intake groove 15 and the dust filter plate 16, so that more airflow passes over the surface of the packaging box after printing. The air blown towards the packaging box is filtered by the dust filter plate 16 to prevent dust in the air from adhering to the surface of the packaging box and causing the printing effect of the packaging box to deteriorate. At the same time, the dust filter plate 16 can be disassembled by loosening the bolts for easy cleaning.

[0022] refer to Figure 5 Hollow support legs 17 are fixedly connected to the four corners of the bottom of the support plate 1. A second electric telescopic rod 18 is fixedly connected to the top of the inner wall of the hollow support leg 17. A universal wheel 19 is fixedly connected to the output end of the second electric telescopic rod 18. The bottom of the surface of the universal wheel 19 is higher than the bottom of the hollow support leg 17.

[0023] This embodiment provides stable support for the device by setting up hollow support legs 17, a second electric telescopic rod 18, and casters 19 in a coordinated manner. When the device needs to be moved, the second electric telescopic rod 18 can be activated to extend it, which drives the casters 19 to move downwards, so that the hollow support legs 17 extend outwards and the bottom contacts the ground, making it easy to push the device and convenient for users to use.

[0024] refer to Figure 2 The surface of the conveyor belt mechanism 3 is fixedly connected with a number of evenly distributed dividing strips 20. Rubber side strips 21 are fixedly connected to both the front and rear sides of the surface of the conveyor belt mechanism 3. The front and rear ends of the dividing strips are in contact with the inner side of the rubber side strips 21. The surface of the conveyor belt mechanism 3 is provided with a smooth coating.

[0025] In this embodiment, by setting up separator bars 20, when the packaging box is placed above the conveyor belt mechanism 3, the packaging box is placed between two adjacent separator bars 20. The separator bars 20 block the packaging box, preventing the packaging box from being squeezed and overlapping, which would affect the printing effect. At the same time, the separator bars 20 can push the packaging box to the right to prevent the packaging box from getting stuck. By setting up rubber side strips 21, the packaging box is blocked, preventing the packaging box from falling off the outside before entering the two sets of rollers 11.

[0026] refer to Figure 1 An L-shaped support frame 22 is fixedly connected to the right side of the bottom of the bearing plate 1. A collection box 23 located below the right end of the conveyor belt mechanism 3 is attached to the top of the L-shaped support frame 22. A sponge pad is fixedly connected to the bottom of the inner wall of the collection box 23.

[0027] This embodiment, through the coordinated arrangement of the L-shaped support frame 22 and the collection box 23, allows for the centralized collection of printed packaging boxes, making it convenient for users to pick them up. The sponge pad provides cushioning protection for falling packaging boxes, preventing damage when they fall into the collection box 23.

[0028] This invention involves placing the packaging box to be printed above the conveyor belt mechanism 3. The conveyor belt mechanism 3 moves the packaging box to the right. Then, according to the specifications of the packaging box, the first electric telescopic rod 6 is activated. The activation of the first electric telescopic rod 6 causes two straightening push plates 7 to move closer together. When the two straightening push plates 7 move closer together, they also cause two sets of guide rods 8 and push frames 9 to move closer together until the surface of the roller 11 is in contact with the surface of the packaging box, pushing the packaging box to the center line position of the conveyor belt mechanism 3, so that it can be aligned with the output end of the printer body 5 when passing by the printer body 5. At this time, the extension of the first electric telescopic rod 6 is stopped, and the position of the roller 11 is fixed. Subsequently, when the packaging box moves to the right by the conveyor belt mechanism 3, the front... Both sides of the roller 11 are in contact with the surface of the roller 11. The roller 11 rolls and gathers the packaging box to the center of the conveyor belt mechanism 3 without affecting the movement of the packaging box. At the same time, through the cooperation of the compression spring 10 and the guide rod 8, when the position of the packaging box is biased to one side, the roller 11 and the push frame 9 retract outward and then push the packaging box towards the center through the rebound of the compression spring 10, so as to avoid the packaging box being squeezed and damaged. Thus, the gap of the correction mechanism can be pre-adjusted according to the width of the material to be printed as needed, and the material is limited when moving. This ensures that the material is directly under the printer when printing, avoiding printing deviation. It also allows for uninterrupted printing of the same batch of materials of the same specifications, improving printing efficiency.
