Description

Technical Field

[0001] The utility model relates to the field of carton printing, and particularly relates to an electrostatic elimination device for carton printing. Background Technique

[0002] A carton printing machine is an indispensable device in the packaging industry, used for printing words, patterns and other information on the surface of cartons. The printing process mainly includes key steps such as plate mounting, ink coating, embossing and paper feeding. However, during the printing process, the contact and friction between the carton and the equipment, as well as the printing process itself, will generate a large amount of static electricity. The existence of static electricity has a direct negative impact on the printing quality, mainly reflected in the following aspects: uneven ink: Static electricity may cause uneven distribution of ink, affecting the clarity and beauty of the printed pattern. Poor adhesion: Under the action of static electricity, the ink may not adhere firmly to the surface of the carton, resulting in poor printing effect. Paper adhesion: Static electricity causes the papers to attract each other, easily causing paper adhesion during the conveying process, affecting the continuity and efficiency of printing. Positioning problem: Static electricity may interfere with the positioning of the paper during the printing process, resulting in inaccurate positions of the printed patterns. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an electrostatic elimination device for carton printing to solve the problems in the above background technique.

Detailed implementation

[0020] As Figures 1 to 4 shown, an electrostatic elimination device for carton printing includes a printing mechanism 1 on a conveying mechanism 2, and an electrostatic elimination mechanism 3 is provided at the outlet of the printing mechanism 1. The electrostatic elimination mechanism 3 is arranged between two conveying mechanisms 2;

[0021] On the fixing plate 301 in the electrostatic elimination mechanism 3, there is a lifting sliding plate 302. On the side of the sliding plate 302 opposite to the fixing plate 301, a horizontal ion wind bar 303 is fixedly installed. At both ends of one side of the fixing plate 301 and the sliding plate 302, there are two relatively moving vertical ion wind bars 306. The horizontal ion wind bar 303 and the vertical ion wind bar 306 form a square frame, and the printed cardboard moves within the square frame. The lifting adjustment of the sliding plate 302 in the electrostatic elimination mechanism 3 can drive the horizontal ion wind bar 303, thereby adjusting the distance between the two horizontal ion wind bars 303. At the same time, the distance between the vertical ion wind bars 306 is also adjusted by relative movement, so as to adjust the size of the formed square frame to adapt to cardboard of different sizes. Through the vertical ion wind bar 306 and the horizontal ion wind bar 303, the static electricity on the cardboard can be eliminated in all directions.

[0022] The cardboard is transported by the conveying mechanism 2 to the printing mechanism 1 to complete the printing process. The electrostatic elimination mechanism 3 is installed at the outlet of the printing mechanism 1 to ensure that the cardboard is immediately subjected to electrostatic elimination after leaving the printing area.

[0023] The ion wind generated by the horizontal ion wind bar 303 and the vertical ion wind bar 306 covers the entire surface of the cardboard, neutralizing the static charges on the cardboard. By adjusting the lifting of the sliding plate 302 and the relative movement of the vertical ion wind bar 306, the size of the ion wind coverage area can be changed to adapt to cardboard of different sizes.

[0024] The adjustable characteristics of the sliding plate 302 and the vertical ion wind bar 306 allow the device to adapt to various cardboard sizes, improving production flexibility. The design of the ion wind bar ensures full coverage of the cardboard surface. Regardless of the size of the cardboard, static electricity can be effectively eliminated. By reducing the influence of static electricity, the printing effect can be significantly improved, and printing defects caused by static electricity can be avoided.

[0025] Preferably, guide posts 304 and lead screws 305 are provided between the two ends of the fixed plate 301 and the sliding plate 302. One end of the guide post 304 is fixed on the fixed plate 301, and the other end abuts against the sliding plate 302 through a sliding sleeve and slides thereon. One end of the lead screw 305 is fixed on the fixed plate 301, and the other end is threadedly connected to the sliding plate 302 through a nut sleeve. Rotating the lead screw 305 can drive the sliding plate 302 to perform lifting adjustment, and the guide post 304 can ensure the smoothness of its movement.

[0026] The guide post 304 guides the sliding plate to move up and down in a straight line direction, ensuring that it will not shift or shake during the lifting process and maintaining a stable running track. The guide post is usually cylindrical, with one end fixed on the fixed plate 301 and the other end passing through the sliding sleeve and connected to the sliding plate 302. The sliding sleeve can slide freely along the guide post but will not rotate, thus ensuring the linear movement of the sliding plate.

[0027] The lead screw 305 is a transmission element that converts rotational motion into linear motion. In this device, the rotation of the lead screw can drive the sliding plate 302 to perform lifting adjustment.

[0028] One end of the lead screw is fixed on the fixed plate 301, and the other end is threadedly connected to the sliding plate 302 through a nut sleeve. When the lead screw rotates, the nut sleeve will move up or down along the thread of the lead screw, thereby driving the sliding plate 302 to lift. The pitch of the lead screw determines the lifting speed and accuracy of the sliding plate.

[0029] By using an external drive source to rotate the lead screw 305, the lifting distance of the sliding plate 302 can be precisely controlled, and then the position of the transverse ion wind rod 303 can be adjusted to adapt to cardboard of different sizes. The combined use of the guide post 304 and the lead screw 305 not only ensures the stability and straightness of the sliding plate 302 but also improves the accuracy of position adjustment, which is crucial for a high-precision static elimination process.

[0030] Preferably, both ends of the fixed plate 301 are fixed on the conveying mechanism 2. A first motor 308 is fixedly provided on one side of the conveying mechanism 2. The output shaft end of the first motor 308 is provided with a main shaft 307 connected thereto. The main shaft 307 is connected to the lead screw 305 through a bevel gear transmission mechanism 309. Both ends of the main shaft 307 abut against the fixed plate 301 through bearing seats and rotate thereon. The first motor 308 drives the main shaft 307 to rotate and drives the lead screw 305 to rotate through the bevel gear transmission mechanism 309, so that the sliding plate 302 can be lifted and adjusted.

[0031] The first motor 308 serves as a power source. The first motor is responsible for providing the power for rotation to drive the entire lifting adjustment system. The motor is fixed on one side of the conveying mechanism 2, which is convenient for installation and maintenance and ensures the stability of the motor during operation.

[0032] The main shaft 307 serves as a connecting member between the first motor 308 and the bevel gear transmission mechanism 309, and is responsible for transmitting the rotational force of the motor. The two ends of the main shaft are supported on the fixed plate 301 through bearing seats, allowing it to rotate freely while maintaining the structural stability and positioning accuracy.

[0033] The bevel gear transmission mechanism 309 is used to change the direction of force transmission, converting the axial rotation of the main shaft 307 into the axial rotation of the lead screw 305 to achieve linear motion. It includes a pair of meshing bevel gears, one of which is installed on the main shaft 307 and the other is coaxially fixed to the lead screw 305.

[0034] Start the first motor 308, and the output shaft rotates accordingly. The output shaft of the motor directly drives the main shaft 307 connected to it to rotate. The bevel gear on the main shaft 307 meshes with the bevel gear on the lead screw 305, transmitting the rotational force to the lead screw 305. The lead screw 305 starts to rotate and, through a threaded connection with the nut sleeve of the sliding plate 302, pushes the sliding plate to rise or fall along the guide post 304. The lifting adjustment of the sliding plate 302 realizes the change in the position of the lateral ion wind rod 303, thus adapting to cardboard of different sizes.

[0035] Preferably, a rotating bidirectional lead screw 310 is provided on one side of the fixed plate 301 and the sliding plate 302. Two vertical ion wind rods 306 are threadedly connected to both ends of the bidirectional lead screw 310 through nut sleeves. A second motor 311 is provided on one side of the bidirectional lead screw 310, and the output shaft of the second motor 311 is connected to the middle of the bidirectional lead screw 310 through a sprocket and a chain. The second motor 311 is fixed on the fixed plate 301 or the sliding plate 302. When the second motor 311 drives the bidirectional lead screw 310 to rotate, the corresponding two vertical ion wind rods 306 can be driven to move relatively, thereby adjusting their spacing.

[0036] The bidirectional lead screw 310 has two sections of threads, and the directions of these two sections of threads are opposite, and are respectively threadedly connected to the nut sleeves on the two vertical ion wind rods 306. When the bidirectional lead screw rotates, the two nut sleeves will approach or move away from each other according to the different thread directions, thereby adjusting the distance between the two vertical ion wind rods 306.

[0037] The second motor 311 is responsible for providing power to drive the bidirectional lead screw 310 to rotate. The second motor is fixed on the fixed plate 301 or the sliding plate 302, and the output shaft of the motor is connected to the middle position of the bidirectional lead screw 310 through a sprocket and a chain. This transmission method can provide sufficient torque and ensure the smoothness and accuracy of the transmission.

[0038] The second motor 311 is started, causing its output shaft to rotate. The motor's output shaft transmits power to the bidirectional screw 310 via a sprocket and chain. As the bidirectional screw begins to rotate, the threads on its two ends, in opposite directions, cause the thread sleeves on the two vertical ion wind rods 306 connected to it to move closer or further away from each other. As the vertical ion wind rods move relative to each other, the distance between them changes, allowing them to accommodate cardboards of varying widths.

[0039] Preferably, the bidirectional screw rods 310 on the fixed plate 301 and the sliding plate 302 are staggered. The staggered arrangement enables the vertical ion wind rods 306 on the fixed plate 301 and the sliding plate 302 to overlap without interfering, thereby ensuring a larger adjustment space between the horizontal ion wind rods 303.

[0040] By staggering the bidirectional screw rods 310 on the fixed plate 301 and the sliding plate 302, the vertical ion wind rods 306 will not collide or obstruct each other during the adjustment process, and can maintain a good operating state even when the spacing between the horizontal ion wind rods 303 changes significantly.

[0041] The bidirectional screw rods 310 are not completely aligned on the fixed plate 301 and the sliding plate 302, but are intentionally offset by a certain distance. In this way, when the sliding plate 302 is raised or lowered, the vertical ion wind rods 306 will be spatially staggered due to the offset arrangement. Even if the spacing between the horizontal ion wind rods 303 is adjusted to a large distance, the vertical ion wind rods 306 will not come into physical contact.

[0042] The staggered arrangement increases the space for adjusting the spacing between the horizontal ion wind bars 303, allowing the equipment to accommodate a wider range of cardboard sizes. It also prevents interference between the vertical ion wind bars 306 during adjustment, reducing unnecessary downtime and adjustment time, and improving production efficiency. This design makes the static elimination device more flexible in processing cardboard of varying sizes, eliminating the need for frequent manual intervention and enhancing automation.

The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
