[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on the printing press. Then, the ink is applied to the place where the text and image are on the printing plate by a person or a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed matter as the printing plate. The invention and development of the printing press plays an important role in the dissemination of human civilization and culture. Since the quality of printed products needs to be continuously improved during the printing process, the tension of the printed product should be properly adjusted. In the existing printing process, it is impossible to adjust directly by human effort, and the tension cannot be adjusted in real time. Moreover, since the vibration of the printing operation affects the auxiliary control tension of the backing paper, it is not convenient to use, which affects the printing quality of the product. Such a tension control device for a printing press is not convenient for adjusting the tension of the brush wheel, which affects the printing quality of the product. Utility Model Content

DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-4 This application is described in further detail.

[0018] The present application embodiment discloses a tension control device for a printing press. Figure 1-2 , including a bottom plate 1, both sides of the upper end of the bottom plate 1 are connected to support plates 2, both sides of one end of the support plate 2 are provided with slide grooves 3, both sides of the inside of the slide groove 3 are connected to fixed grooves 4, one side of the inside of the slide groove 3 is connected to a tension adjustment component 5, a roller 6 is rotatably connected between the two support plates 2, the roller 6 presses the paper, and the tension adjustment component 5 includes a fixed seat 51 installed in the slide groove 3, and one end of the fixed seat 51 is rotatably connected to one side of the roller 6.

[0019] Reference Figure 3-4 A round rod 52 is connected to one side of the upper end of the fixed seat 51, and a sleeve 53 is connected to the upper end of the round rod 52. The upper end of the sleeve 53 is connected to the inner side of the slide groove 3. The upper end of the round rod 52 extends through and extends to the inside of the sleeve 53 and is connected to a pressure plate 54. A spring 55 is sleeved on the outside of the round rod 52, and one end of the spring 55 is connected to one side of the pressure plate 54, and the other end of the spring 55 is connected to one side of the inner wall of the sleeve 53. A connecting rod 57 is connected to one side of the inner side of the fixed seat 51, and a threaded hole 58 is opened at one end of the connecting rod 57. A threaded rod 59 is connected to one side of the inner side of the fixed seat 51, and the threaded rod 59 is located on one side of the threaded hole 58. The threaded rod 59 is rotated, and the threaded rod 59 is threadedly connected to the connecting rod 57. As the threaded rod 59 rotates, the conical plate 510 is driven to move toward one end of the inclined plate 514. One end of the threaded rod 59 extends through and extends to the fixed seat 51, a conical plate 510 is sleeved on the outside of the threaded rod 59, and elastic plates 511 are connected to both sides of the fixed seat 51. The support plate 512 drives the elastic plate 511 to bend, and then drives the fixed block 513 to move to the inside of the fixed groove 4. When the conical plate 510 is no longer in contact with the inclined plate 514, the elastic plate 511 drives the support plate 512 to return to its original position. One end of the elastic plate 511 is connected to the support plate 512, and one end of the support plate 512 is connected to the fixed block 513. One end of the fixed block 513 extends through and extends to the inside of the fixed groove 4. The other end of the support plate 512 is connected to the inclined plate 514. The inclined end of the inclined plate 514 contacts the conical surface of the conical plate 510. The conical plate 510 contacts the inclined plate 514. As the conical plate 510 moves, the inclined plate 514 is pushed to move to both sides.

[0020] The implementation principle of the tension control device of a printing press in the embodiment of the present application is as follows: when in use, in the initial state, the fixed block 513 is located inside the fixed groove 4, and the fixed seat 51 is in a fixed state. When the tension of the roller 6 needs to be adjusted, the threaded rod 59 is rotated, and the threaded rod 59 is threadedly connected with the connecting rod 57. As the threaded rod 59 rotates, the threaded rod 59 is rotated to the outside of the connecting rod 57, and the threaded rod 59 is pulled to one side so that the conical plate 510 is no longer in contact with the inclined plate 514, and the elastic The elastic potential energy of plate 511 drives support plate 512 to move, so that fixed block 513 moves to the inside of fixed seat 51, and fixed seat 51 is in an active state. Pulling fixed seat 51 downward, fixed seat 51 drives round rod 52 to move, and round rod 52 drives pressure plate 54 to move. Pressure plate 54 squeezes spring 55, so that spring 55 is compressed. Spring 55 will apply upward force to fixed seat 51, and then the tension degree of roller 6 can be adjusted by tension adjustment assembly 5, which is convenient for adjusting the tension of roller 6.
