[0001] The utility model relates to the technical field of winding devices, in particular to a winding device for a printing press. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing and paper feeding. Its working principle is to first make the text and images to be printed into a printing plate, install it on the printing press, and then apply ink to the places with text and images on the printing plate manually or by the printing press, and then directly or indirectly transfer it to paper or other substrates, thereby replicating the same printed products as the printing plate. The invention and development of the printing press plays an important role in the dissemination of human civilization and culture. The paper printed by the printing press needs to be reeled up using a reeling device.

[0003] For example, Chinese patent application No. 202123292842.3 discloses a winding device for a printing machine. Through the coordinated use of a sliding seat, a telescopic spring and a tensioning roller, when the printing paper on the outer surface of the tensioning roller is pulled, the tensioning roller can maintain a certain tension under the elastic force of the telescopic spring outside the sliding seat, thereby avoiding the printing paper from being loose as much as possible.

[0004] It has the following defects:

[0005] Since the printing paper itself is light in weight, the force exerted by the printing paper on the telescopic spring is small, and the telescopic spring is easy to adjust the relaxation of the printing paper without deforming under the small force.

[0006] Therefore, those skilled in the art provide a winding device for a printing press to solve the problems raised in the above background technology. Utility Model Content

[0009] The two guide wheels are connected along the two upper ends of the guide wheels, and the guide wheels are connected along the two lower ends of the guide wheels respectively.

[0010] Furthermore, the upper end surfaces of the two fixed vertical plates are fixedly connected to a fixed horizontal plate, the upper end surface of the fixed horizontal plate is fixedly connected to a dryer, and the lower end surface of the fixed horizontal plate is fixedly installed with an air outlet.

[0011] Furthermore, two air outlets are provided, the two air outlets are connected to each other, and the two air outlets are symmetrical about the connecting rod.

[0012] Furthermore, the lower end surfaces of the two air outlets are sequentially provided with a plurality of air outlets, and the two air outlets are both connected to the air dryer.

[0013] Furthermore, two extrusion wheels are rotatably connected between the two fixed vertical plates in sequence, the two extrusion wheels are arranged up and down, and the two extrusion wheels are located between the winding wheel and the guide roller above the winding wheel.

[0014] Furthermore, the two side walls in the slide groove are provided with limit grooves, the outer wall surface of the sliding block is sleeved with a limit block, and the limit block on the outer wall surface of the sliding block inside the limit groove slides in the two limit grooves in the limit groove.

[0015] The beneficial effects of the utility model are:

[0016] The looseness of the printing paper is adjusted by the cooperation of the electric telescopic device, the slide groove, the connecting rod, the rotating wheel and the slider instead of the telescopic spring, so that the problem that the telescopic spring cannot adjust the looseness of the printing paper due to the small force exerted by the printing paper on the telescopic spring can be avoided.

DETAILED DESCRIPTION

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a winding device for a printing machine includes a fixed vertical plate 1, which is provided with two fixed vertical plates 1. The two sides between the two fixed vertical plates 1 are rotatably connected with guide wheels 2 and winding wheels 3, respectively. The upper ends between the two fixed vertical plates 1 are rotatably connected with two guide rollers 4, and the two guide rollers 4 correspond to the positions of the guide wheels 2 and winding wheels 3 respectively. One side wall surface of the two fixed vertical plates 1 is fixedly connected with an electric telescopic device 5, and one side wall surface of the two fixed vertical plates 1 is provided with a slide groove 6, and the positions of the two slide grooves 6 correspond to each other. The two slide grooves 6 are located between the two guide rollers 4, and a connecting rod 7 is provided between the two slide grooves 6. The outer wall surface of the connecting rod 7 is rotatably connected with a rotating wheel 8, and sliders 9 are fixedly connected at both ends of the connecting rod 7. The two sliders 9 pass through the two slide grooves 6 respectively, and the output ends of the two electric telescopic devices 5 are respectively connected to the two sliders 9. The outer wall surface of the winding wheel 3 is rolled with printing paper 10, and the end of the printing paper 10 away from the winding wheel 3 is placed on the upper end surface of the two guide rollers 4 and passes through the guide wheel 2. If the rolled printing paper 10 is loose, the electric retractor 5 is started, and the start of the electric retractor 5 drives the slider 9 to move along the slide 6 toward the printing paper 10, and the movement of the slider 9 drives the connecting rod 7 to move, and the movement of the connecting rod 7 drives the rotating wheel 8 to move. When the rotating wheel 8 contacts the printing paper 10, the rotating wheel 8 continues to move downward, and the movement of the rotating wheel 8 will tighten the loose printing paper 10. The looseness of the printing paper 10 is adjusted by the mutual cooperation of the electric retractor 5, the slide 6, the connecting rod 7, the rotating wheel 8, and the slider 9 instead of the telescopic spring, so that the problem that the telescopic spring cannot adjust the looseness of the printing paper 10 due to the small force of the printing paper 10 on the telescopic spring can be avoided.

[0023] The upper end surfaces of the two fixed vertical plates 1 are fixedly connected with the fixed horizontal plates 12, the upper end surfaces of the fixed horizontal plates 12 are fixedly connected with the air dryer 13, and the lower end surfaces of the fixed horizontal plates 12 are fixedly installed with the air outlet 130. Two air outlets 130 are provided, the two air outlets 130 are connected, and the two air outlets 130 are symmetrical about the connecting rod 7. The lower end surfaces of the two air outlets 130 are sequentially provided with a plurality of air outlets, and the two air outlets 130 are connected with the air dryer 13. When the printing paper 10 passes through the air outlet 130, the air dryer 13 is started, and the air dryer 13 will blow the heated air to the printing paper 10 through the air outlet 130. The wind blowing to the printing paper 10 will air dry the handwriting or pattern on the printing paper 10, so as to effectively avoid the printing effect of the handwriting or pattern on the printing paper 10 being affected by rolling up the handwriting or pattern before it dries.

[0024] Two squeezing wheels 11 are connected to the two fixed vertical plates 1 in rotation in sequence. The two squeezing wheels 11 are arranged up and down, and the two squeezing wheels 11 are located between the winding wheel 3 and the guide roller 4 above the winding wheel 3. The two side walls of the slide 6 are provided with limit grooves 14, and the outer wall of the slider 9 is sleeved with limit blocks 15. The limit blocks 15 on the outer wall of the slider 9 inside the limit groove 14 slide in the two limit grooves 14 in the limit groove 14. The arrangement of the two squeezing wheels 11 facilitates squeezing the printing paper 10, so that the printing paper 10 is more neat, thereby reducing the wrinkles of the printing paper 10 when it is rolled up.

[0025] The working principle of the utility model is:

[0026] First, one end of the printing paper 10 is passed through the guide wheel 2, and the printing paper 10 passing through the guide wheel 2 is placed on the upper end surfaces of the two guide rollers 4. One end placed on the upper end surfaces of the two guide rollers 4 passes between the two squeezing wheels 11 and is rolled up on the winding wheel 3. The printing paper 10 is rolled up by rotating the winding wheel 3. During the rolling process of the printing paper 10, the air dryer 13 is started. The air dryer 13 blows the heated air to the printing paper 10 through the air outlet 130. The air blown to the printing paper 10 will dry the handwriting or pattern on the printing paper 10. If the rolled printing paper 10 is loose, the electric retractor 5 is started. The start of the electric retractor 5 drives the slider 9 to move along the slide groove 6 toward the printing paper 10. The movement of the slider 9 drives the connecting rod 7 to move. The movement of the connecting rod 7 drives the rotating wheel 8 to move. When the rotating wheel 8 contacts the printing paper 10, the rotating wheel 8 continues to move downward. The movement of the rotating wheel 8 will tighten the loose printing paper 10.
