Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and more specifically to a carton printing press with a flipping function. Background Technology

[0002] As an indispensable part of modern logistics, cardboard boxes bear the important responsibilities of packaging, protecting products, and ensuring aesthetics. In the production and processing of cardboard boxes, printing presses are used to print patterns and text on the surface of the boxes to improve their appearance. Cardboard box printing machines are specialized equipment that print text, patterns, and information onto the surface of cardboard boxes. They mainly achieve the printing function through processes such as plate mounting, inking, printing, and paper feeding. Their application areas cover industries such as packaging and logistics. Core components include printing tables, ink rollers, and conveyor tables.

[0003] Current technology has shortcomings: In order to improve efficiency, the printing process of cartons uses conveyor belts to move the cartons to the printing components for printing, adopting an assembly line operation. However, cartons need to be printed on multiple sides, so they need to be flipped for printing. In the current printing press, flipping is mostly done manually, which is time-consuming and labor-intensive, and it is impossible to accurately control the distance between adjacent cartons, affecting subsequent printing. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a carton printing machine with a flipping function to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carton printing machine with a flipping function, including a base plate, and further including: a flipping mechanism and a conveying mechanism. The top end of the base plate is fixedly connected to the bottom end of the conveying mechanism, and the bottom end of the flipping mechanism is fixedly connected to the bottom end of the flipping mechanism. The conveying mechanisms on both sides are symmetrically distributed along the center of the flipping mechanism. The flipping mechanism includes a support frame, the bottom end of the support frame is fixedly connected to the top end of the base plate, and a mounting shaft is movably sleeved on the side of the support frame. A stepper motor is fixedly connected to the side of the support frame, and the output shaft of the stepper motor is fixedly connected to the side of the mounting shaft. A support rod is fixedly connected to the side of the mounting shaft, and the support rods are evenly distributed on the side of the mounting shaft. The conveying mechanism and the support rods are staggered.

[0006] Furthermore, the conveying mechanism includes a mounting frame, the bottom end of which is fixedly connected to the top end of the base plate. A transmission wheel is movably connected to the inner side wall of the mounting frame, a sprocket is fixedly connected to the side of the transmission wheel, and a chain is drivenly connected to the side of the sprocket.

[0007] Furthermore, the support rod has a Z-shaped structure, the top end of the transmission wheel is on the same horizontal line as the center of the mounting shaft, and the top end of the transmission wheel is on the same horizontal line as the center of the support rod.

[0008] Furthermore, a mounting groove is provided on the side of the support rod, a return spring is fixedly connected to the side of the mounting groove, a pressure plate is fixedly connected to the side of the return spring, a buffer spring is fixedly connected to the side of the mounting groove, and a tactile switch is fixedly connected to the side of the buffer spring.

[0009] Furthermore, a suction cup is fixedly connected to the top of the support rod, and an air guide tube is fixedly connected inside the mounting shaft at the position corresponding to the support rod. The top of the air guide tube is fixedly connected to the bottom of the suction cup. An annular groove is formed on the side of the mounting shaft at the position corresponding to the air guide tube. An air guide ring is movably sleeved on the side of the annular groove. A connecting pipe is fixedly connected to the side of the air guide ring, and a negative pressure device is fixedly connected to the bottom of the connecting pipe.

[0010] Furthermore, an air cavity is formed inside the air guide ring corresponding to the position of the air guide pipe, the connecting pipe is located in the position of the air cavity, and the side of the air guide ring is fixedly connected to the side of the support frame.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model uses six support rods evenly distributed on the side of the mounting shaft. Initially, the left support rod is located below the conveying mechanism, and the right support rod is located above the conveying mechanism. The left conveying mechanism transports the carton to the position of the support rod. The stepper motor drives the mounting shaft to rotate 60 degrees clockwise, so that the left support rod lifts the carton on the conveying mechanism. The next support rod moves to the bottom of the conveying mechanism, the support rod directly above the right conveying mechanism moves to the bottom of the conveying mechanism, and the next support rod moves to the top of the conveying mechanism, placing the carton on the conveying mechanism for transport. This achieves the flipping of the carton and reduces manual operation.

[0013] 2. In this utility model, when the cardboard box is conveyed by the conveyor mechanism to the bending point of the support rod, it comes into contact with the pressure plate, causing the pressure plate to retract into the mounting groove and contact the tactile switch. The tactile switch then controls the stepper motor to drive the mounting shaft to rotate 60 degrees, which is beneficial for realizing automatic control of the equipment.

[0014] 3. In this invention, as the air guide tube rotates with the mounting shaft, the corresponding air guide tube moves to the air chamber, connecting the air guide tube to the negative pressure device. When the negative pressure device operates, it creates negative pressure at the suction cup through the connecting pipe, mounting shaft, and air guide tube, thereby adsorbing the carton onto the support rod to prevent it from falling. At the same time, the next support rod moves to below the left transmission wheel, and the right support rod moves downward, moving the support rod directly above the transmission wheel. The corresponding air guide tube is then misaligned with the air chamber, causing the negative pressure at the suction cup to disappear. The carton falls onto the right transmission wheel and is conveyed to the right, which helps ensure that the distance between the cartons on both sides of the conveying mechanism remains unchanged, facilitating subsequent printing.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The carton printing machine with flipping function involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1 to 6 This utility model provides a carton printing machine with a flipping function, including a base plate 1, and further including a flipping mechanism 2 and a conveying mechanism 3. The top end of the base plate 1 is fixedly connected to the bottom end of the conveying mechanism 3, and the bottom end of the flipping mechanism 2 is fixedly connected to the bottom end of the conveying mechanism 3. The two conveying mechanisms 3 are symmetrically distributed along the center of the flipping mechanism 2. The flipping mechanism 2 includes a support frame 201, the bottom end of the support frame 201 is fixedly connected to the top end of the base plate 1, and a mounting shaft 207 is movably sleeved on the side of the support frame 201. A stepper motor 203 is fixedly connected to the side of the support frame 201, and the output shaft of the stepper motor 203 is fixedly connected to the side of the mounting shaft 207. Support rods 204 are fixedly connected to the side of the mounting shaft 207, and the support rods 204 are evenly distributed on the side of the mounting shaft 207. On the surface, the conveying mechanism 3 and the support rods 204 are staggered. The six support rods 204 are evenly distributed on the side of the mounting shaft 207. Initially, the left support rod 204 is located below the conveying mechanism 3, and the right support rod 204 is located above the conveying mechanism 3. The left conveying mechanism 3 transports the carton to the position of the support rod 204. The stepper motor 203 drives the mounting shaft 207 to rotate 60 degrees clockwise, so that the left support rod 204 lifts the carton on the conveying mechanism 3. The next support rod 204 moves to the bottom of the conveying mechanism 3, the support rod 204 directly above the right conveying mechanism 3 moves to the bottom of the conveying mechanism 3, and the next support rod 204 moves to the top of the conveying mechanism 3, placing the carton on the conveying mechanism 3 for transport, realizing the flipping of the carton and reducing manual operation.

[0024] The conveying mechanism 3 includes a mounting frame 301, the bottom of which is fixedly connected to the top of the base plate 1. A transmission wheel 303 is movably connected to the inner side wall of the mounting frame 301. A sprocket 302 is fixedly connected to the side of the transmission wheel 303. A chain 304 is driven to the side of the sprocket 302. The transmission wheel 303 rotates synchronously through the chain 304 and the sprocket 302. The carton is conveyed to the right by the transmission wheel 303 driven by the drive device.

[0025] The support rod 204 has a Z-shaped structure. The top of the transmission wheel 303 is on the same horizontal line as the center of the mounting shaft 207, and the top of the transmission wheel 303 is on the same horizontal line as the center of the support rod 204. This ensures that when the support rod 204 is on the left side, it is located below the conveying mechanism 3, and the bend of the support rod 204 blocks the carton. After the support rod 204 rotates 180 degrees with the mounting shaft 207, it is located directly above the conveying mechanism 3, and it remains parallel to the conveying mechanism 3, ensuring that the carton falls vertically onto the conveying mechanism 3 for conveying.

[0026] The support rod 204 has a mounting groove 210 on its side. A return spring 212 is fixedly connected to the side of the mounting groove 210. A pressure plate 211 is fixedly connected to the side of the return spring 212. A buffer spring 209 is fixedly connected to the side of the mounting groove 210. A tactile switch 213 is fixedly connected to the side of the buffer spring 209. When the carton is conveyed to the bending point of the support rod 204 by the conveying mechanism 3, it contacts the pressure plate 211, causing the pressure plate 211 to retract into the mounting groove 210 and contact the tactile switch 213. The tactile switch 213 then controls the stepper motor 203 to rotate the mounting shaft 207 by 60 degrees.

[0027] The support rod 204 has a suction cup 205 fixedly connected to its top end. An air guide tube 214 is fixedly connected inside the mounting shaft 207 at a position corresponding to the support rod 204. The top end of the air guide tube 214 is fixedly connected to the bottom end of the suction cup 205. An annular groove 216 is formed on the side of the mounting shaft 207 at a position corresponding to the air guide tube 214. An air guide ring 206 is movably fitted onto the side of the annular groove 216. A connecting pipe 208 is fixedly connected to the side of the air guide ring 206. The bottom end of the connecting pipe 208 is fixedly connected to… There is a negative pressure device 202. The suction cups 205 on the support rod 204 at the same angle are connected through the air guide pipe 214. When the carton is on the support rod 204, the negative pressure device 202 operates. Through the connecting pipe 208, the mounting shaft 207 and the air guide pipe 214, a negative pressure is formed at the suction cups 205, thereby adsorbing the carton on the support rod 204 to prevent it from falling. When the carton moves with the support rod 204 to directly above the conveying mechanism 3, the corresponding suction cups 205 stop sucking air, so that the carton falls onto the conveying mechanism 3.

[0028] The air guide ring 206 has an air chamber 215 inside corresponding to the position of the air guide pipe 214. The connecting pipe 208 is located in the air chamber 215. The side of the air guide ring 206 is fixedly connected to the side of the support frame 201. Initially, the air guide ring 206 blocks the air guide pipe 214 on the left support rod 204, preventing the suction cup 205 from breathing normally. As the mounting shaft 207 rotates above the conveying mechanism 3, the corresponding air guide pipe 214 moves to the air chamber 215, connecting the air guide pipe 214 with the negative pressure device 202. A negative pressure is formed at the suction cup 205 on the corresponding support rod 204 to adsorb the carton. As the mounting shaft 207 rotates above the right conveying mechanism 3, the corresponding air guide pipe 214 and the air chamber 215 are misaligned, causing the negative pressure at the suction cup 205 to disappear. The carton falls above the conveying mechanism 3, realizing the automatic fixing and release of the carton.

[0029] The working principle of this utility model is as follows: During use, the drive device rotates the transmission wheel 303, and the chain 304 and sprocket 302 achieve synchronous rotation of the transmission wheel 303, conveying the carton to the right. The carton to be printed is placed on top of the left transmission wheel 303 for conveying. When the carton contacts the pressure plate 211, the pressure plate 211 is retracted into the mounting groove 210 and contacts the tactile switch 213. The tactile switch 213 controls the stepper motor 203 to drive the mounting shaft 207 to rotate 60 degrees. The corresponding air guide pipe 214 moves to the air chamber 215, so that the air guide pipe 214 is connected to the negative pressure device 202. 02 Operation: Through the connecting pipe 208, mounting shaft 207, and air guide pipe 214, a negative pressure is formed at the suction cup 205, thereby adsorbing the carton onto the support rod 204 to prevent it from falling. At the same time, the next support rod 204 moves to below the left transmission wheel 303, while the right support rod 204 moves downward, moving the support rod 204 to directly above the transmission wheel 303. The corresponding air guide pipe 214 is misaligned with the air chamber 215, causing the negative pressure at the suction cup 205 to disappear. The carton falls onto the right transmission wheel 303 and is conveyed to the right, realizing automatic carton flipping and ensuring that the distance between the cartons on both sides of the conveying mechanism 3 remains unchanged during the conveying process.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
