Technical Field
[0001] The present application relates to the technical field of positioning devices for printing presses, and in particular to a positioning device for printing presses. Background Art
[0002] A printing press is a machine for printing text and images. It is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. The text and images to be printed are first made into printing plates and mounted on printing presses. Ink is then applied to the places with text and images on the printing plates manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby reproducing printed products that are identical to the printing plates.
[0003] When an existing printing machine prints the production date, instructions and other text on a paper box or other food packaging box, the table surface will shift due to the vibration of the machine, causing the production date, instructions and other text to shift when transferred to the packaging box, affecting the quality and effectiveness of the printed product. A technician in this field has provided a positioning device for a printing machine to solve the problems raised in the above background technology. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the present application provides a positioning device for a printing press.
[0005] The present application provides a positioning device for a printing press using the following technical solution:
[0006] A positioning device for a printing press comprises a conveying device, wherein fixed plates are fixedly installed on the outside of the conveying device near both sides, a positioning assembly is arranged on one side of the fixed plate, the positioning assembly comprises a guide plate, an electric push rod is fixedly installed on one side of the guide plate, one end of the electric push rod is fixedly connected to the fixed plate, a positioning frame plate is arranged on the other side of the guide plate, a driving roller is arranged inside the positioning frame plate, two groups of fixed blocks are fixedly installed on opposite sides of the guide plate and the positioning frame plate, each group of fixed blocks has four fixed blocks, the four fixed blocks are vertically placed in pairs, a V-shaped linkage rod is movably installed and connected between the two fixed blocks, and a guide rod is movably installed between the two V-shaped linkage rods located in the vertical position.
[0007] Preferably, four springs are fixedly installed between the two guide rods, and the four springs are vertically equidistantly arranged.
[0008] Preferably, a rotating assembly is provided on one side of the conveying device, and the rotating assembly includes a circular frame, a CCD camera is fixedly mounted on the upper end of the circular frame, and a camera is fixedly mounted on the inner top of the circular frame.
[0009] Preferably, a fixing plate is fixedly mounted on the inner bottom end of the circular frame, a disc column is movably engaged with the upper end of the fixing plate, and a vacuum suction cup is fixedly embedded on the upper end of the disc column.
[0010] Preferably, a plurality of racks are fixedly mounted in an annular shape near the lower end of the outer portion of the disc column.
[0011] Preferably, a circular gear column is fixedly mounted on the upper end of the fixed plate via a stepping motor, and the circular gear column is meshed and matched with the rack.
[0012] In summary, the present application includes the following beneficial technical effects: by setting the positioning assembly, the two electric push rods are started, and the positioning frame plates are located at the two sides of the paper box. Due to the action of the springs, the four V-shaped linkage rods have a tendency to move outward, and can only squeeze the two positioning frame plates to move relative to each other, so that the paper box can be limited and moved. After the driving roller rotates, it is prevented that the positioning frame plate exerts too much pressure on the paper box, which makes it inconvenient to move the paper box.
[0013] By setting up a rotating component, when printing, not only the position of the paper box needs to be located, but also the printing direction of the paper box needs to be located. When the paper box is placed on the disc column, an electrical signal is given to the stepper motor to rotate the circular gear column, thereby driving the disc column to rotate, and then rotating the paper box to make the printing direction of each paper box consistent.

First, the carton is placed on the conveying device 1, and the two electric push rods 5 are started through the positioning assembly 3. After the positioning frame plates 7 are located on both sides of the carton, the four V-shaped linkage rods 10 have a tendency to move outward due to the action of the springs 12, and can only squeeze the two positioning frame plates 7 to move relative to each other, so that the carton can be limitedly moved. After the driving roller 8 rotates, it prevents the positioning frame plates 7 from exerting too much pressure on the carton, which makes it inconvenient to move the carton.
[0020] In this embodiment, four springs 12 are fixedly installed between the two guide rods 11, and the four springs 12 are vertically equidistantly arranged.
[0021] In this embodiment, a rotating component 4 is provided on one side of the conveying device 1, and the rotating component 4 includes a return frame 13, a CCD camera 14 is fixedly installed on the upper end of the return frame 13, and a camera 15 is fixedly installed on the inner top of the return frame 13. When printing, it is necessary not only to locate the position of the paper box, but also to locate the printing direction of the paper box, when the paper box is placed on the disc column 16.
[0022] In this embodiment, a fixed plate 18 is fixedly installed at the inner bottom end of the circular frame 13, and a disc column 16 is movably engaged with the upper end of the fixed plate 18. A vacuum suction cup 17 is fixedly embedded at the upper end of the disc column 16. After the vacuum suction cup 17 is started to adsorb the paper box, the CCD camera 14 starts working, and the camera 15 scans the position of the paper box.

An electrical signal is given to the stepper motor to rotate the circular gear column 20, thereby driving the disk column 16 to rotate, and then rotating the paper box to make the printing direction of each paper box consistent.
[0025] The implementation principle of a positioning device for a printing machine in the embodiment of the present application is as follows: first, a paper box is placed on a conveying device 1, and two electric push rods 5 are started through the positioning assembly 3. After the positioning frame plates 7 are located on both sides of the paper box, the four V-shaped linkage rods 10 have a tendency to move outward due to the action of the springs 12, and can only squeeze the two positioning frame plates 7 to move relative to each other, so that the paper box can be limited and moved. After the driving roller 8 rotates, it prevents the positioning frame plates 7 from exerting too much pressure on the paper box, which makes it inconvenient to move the paper box. During printing, not only the position of the paper box needs to be positioned, but also the printing direction of the paper box needs to be positioned. When the paper box is placed on the disc column 16, an electrical signal is given to the stepping motor to rotate the circular gear column 20, thereby driving the disc column 16 to rotate, and then the paper box is rotated to make the printing direction of each paper box consistent.
