[0020] A multi-sided flipping device for a printing press with the above structure. When in use, printed materials are conveyed on the support 1. At this time, the printed materials are first wound around each first guide roller 3 in sequence and conveyed upwards, and then the product is wound through the fourth guide roller 6 arranged diagonally, so that the printed materials are conveyed towards the third guide roller 5 in a direction of 90 degrees through the fourth guide roller 6. The printed materials are wound around the third guide roller 5, and at the same time, the printed materials are wound and conveyed towards the fifth guide roller 7. Finally, the printed materials are conveyed towards the printing position through the second guide roller 4. After the printed materials are conveyed through the fourth guide roller 6, the third guide roller 5, and the winding and conveying of the fifth guide roller 7, their front and back sides are changed. The fourth guide roller 6 and the fifth guide roller 7 are installed on the support 1 through the support part 100, and at the same time, the fourth guide roller 6 and the fifth guide roller 7 are fixed or disassembled on the support part 100 through the fixing part 200. During the installation of the flipping device, the swinging angle of the support 1 is adjusted through the swinging mechanism 300. Compared with the prior art, it can automatically realize the flipping of the front and back sides of the printed materials, can conveniently disassemble and replace the roller body, and can change the horizontal angle of the flipping device to meet different production requirements.

[0021] As Figure 2 shown, in some embodiments of the present invention, the support part 100 includes fixing plates 2 fixed at the four corners of the support 1. First support seats 101 are fixed on the fixing plates 2 arranged at two of the diagonals, and second support seats 102 higher than the first support seats 101 are fixed on the fixing plates 2 arranged at the other two diagonals. The fourth guide roller 6 is installed on the first support seats 101 arranged diagonally, and the fifth guide roller 7 is installed on the second support seats 102 arranged diagonally.

[0022] As Figure 3 shown, in some embodiments of the present invention, in order to achieve the effect of fixing the fourth guide roller 6 and the fifth guide roller 7 on the support part 100, the fixing part 200 includes guide rods 201 symmetrically fixed on each of the first support seats 101 and the second support seats 102. Sliders 202 are movably inserted on every two symmetrically arranged guide rods 201. Guide grooves 203 are symmetrically arranged above each of the first support seats 101 and the second support seats 102. Each slider 202 is movably inserted in the guide groove 203. A baffle 204 is movably hinged on each slider 202. Through holes 205 are provided on each baffle 204. Screw holes 206 are provided in the middle above each of the first support seats 101 and the second support seats 102.

[0023] When a multi-sided flipping device for a printing press with the above structure is in operation, by the user pushing the slider 202, the slider 202 moves along the guide rod 201 and the guide groove 203. At this time, the slider 202 covers the shaft ends of the fourth guide roller 6 and the fifth guide roller 7. Then the user swings the baffle 204 downward, so that the baffle 204 flips onto the first support seat 101 or the second support seat 102. At this time, the user passes a screw through the through hole 205 and twists the screw, so that the screw is screwed into the screw hole 206, and the baffle 204 is fixed on the first support seat 101 or the second support seat 102.

[0024] As Figure 3 and 4 shown, in some embodiments of the present invention, in order to achieve the effect of adjusting the swing angle of the adjusting bracket 1, the swing mechanism 300 includes bolts 303 movably sleeved on the four corners of the fixed plate 2. Connecting plates 301 are fixed at the four corners below the bracket 1. Waist-shaped slots 302 are obliquely penetrated through each of the connecting plates 301. Connecting rods 304 are arranged in each of the waist-shaped slots 302. Stopping shafts 305 are fixed on the upper and lower sides of each of the connecting rods 304. Every two of the stopping shafts 305 are arranged on the upper and lower sides of the fixed plate 2. A threaded sleeve 306 is arranged below the connecting rod 304. The threaded sleeve 306 is in threaded cooperation with the bolt 303.

[0025] When a multi-sided flipping device for a printing press with the above structure is in operation, by the user rotating the bolt 303, the bolt 303 drives the threaded sleeve 306 to move downward. While the threaded sleeve 306 moves, it drives the connecting rod 304 to move. The connecting rod 304 drives the stopping shaft 305 to move. When the symmetrically arranged stopping shafts 305 move, they drive the connecting plate 301 to swing, and at the same time the connecting rod 304 corresponds to the waist-shaped slot 302.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
