Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of book printing machines, and in particular relates to a book printing machine with a material feeding deviation prevention structure. Background Art
[0002] Book printing press is a device used to print various books. Its working principle is mainly to print the text and images on the printing plate by transferring ink or toner. Specifically, the printing image and text are first made on the printing plate by computer plate making or manual plate making; then, the image and text part is processed to be slightly higher than the blank part, forming a surface that can transfer ink; then, the ink or toner is applied to the surface of the image and text through a roller or nozzle, and then the ink or toner is transferred to these materials by paper or other printing materials; finally, after heating or exposure curing, the printing image and text is completed.
[0003] When a book printing machine prints paper, the paper needs to be fed into the book printing machine, and the paper will be offset during the feeding process. The offset is because during the feeding process, as the paper rotates, the paper will offset to both sides, resulting in an offset between the production printing position and the paper position. In view of this, we provide a book printing machine with an anti-feeding offset structure to solve the above problem. Utility Model Content
[0004] The purpose of the utility model is to provide a book printing machine with a structure to prevent material loading deviation, aiming to solve the problem in the prior art that paper will deviate during the feeding process. The deviation is because during the feeding process, as the paper rotates, the paper will deviate to both sides, resulting in a deviation between the production printing position and the position of the paper. In view of this, we provide a book printing machine with a structure to prevent material loading deviation to solve the above problem.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a book printing machine with an anti-feeding deviation structure, comprising a printing machine body, a guide roller is assembled inside the printing machine body, a feeding roller is arranged at the front end of the printing machine body, two corresponding supporting blocks are installed at the top of the printing machine body near the guide roller, and a fixing block is transversely installed at the top of the two supporting blocks, a bidirectional screw is installed inside the fixing block, one end of the bidirectional screw is connected to a bearing, a servo motor is installed on the side wall of the fixing block, a thread sleeve is threadedly connected to the surface of the bidirectional screw, a fixing plate is connected to the bottom end of the fixing plate, an adjusting plate is movably connected to the bottom end of the fixing plate, a pressing roller is installed on the inner side wall of the adjusting plate, a screw is connected to the outer side wall of the fixing plate, and a thread groove is opened on the outer side wall of the adjusting plate.
[0006] As a preferred embodiment of the book printing machine with a feeding deviation prevention structure of the utility model, the surfaces of the bidirectional screw rods have corresponding threads in different directions, and the bidirectional screw rods are rotationally connected to the fixed block via a bearing.
[0007] As a preferred embodiment of the book printing machine with a feeding deviation prevention structure of the utility model, the fixing plate forms a threaded motion through the thread sleeve and the bidirectional lead screw.
[0008] As a preferred embodiment of the book printing machine with a feeding deviation prevention structure of the utility model, the output shaft of the servo motor is connected to the other end of the bidirectional lead screw.
[0009] As a preferred embodiment of the book printing machine with a feeding deviation prevention structure of the utility model, four thread grooves are longitudinally opened downward at equal intervals, and the thread grooves are threadedly connected to the screws.
[0010] As a preferred embodiment of the book printing machine with a feeding deviation prevention structure of the utility model, the adjustment plate is fixedly connected to the fixing plate by screws.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model uses the cooperation of the bidirectional lead screw and the wire sleeve to allow the fixed plate to drive the position of the adjusting plate to change, so that the adjusting plate is close to the two sides of the paper on the guide roller to limit the paper. At the same time, the cooperation of the adjusting plate and the fixed plate allows the clamping roller to contact the top of the two sides of the paper, thereby forming a downward squeeze on the paper to avoid the situation where the two sides of the paper are warped. In summary, when the printing machine body is working, the position of the paper can be limited to reduce the deviation of feeding, and the warping of the two sides of the paper can also be reduced, thereby improving the practicality of the printing machine body.
