Description

Technical Field

[0001] The utility model belongs to the field of printing equipment, and particularly relates to a winding and feeding device for a decorative paper printing machine. Background Art

[0002] With the progress of technology, the production speed of production equipment is correspondingly faster and faster, and the quality requirements for raw material rolls are getting higher and higher. For example, for the material roll wound after printing by a printing machine, whether it is subjected to a suitable pressure roller pressure during winding and whether this pressure has reasonable stability are very important influencing factors determining its winding quality. The pressure rollers on existing printing machines that cooperate with the winding rollers usually provide the pressure on the winding rollers by their own gravity. However, different materials can withstand different pressures due to different material properties, etc. Therefore, since the pressure provided by a single pressure roller cannot be flexibly changed, it cannot meet the high-quality winding requirements of different materials. Content of the Utility Model

[0003] The purpose of the utility model is to provide a winding and feeding device for a decorative paper printing machine with adjustable pressure and good pressure stability.

[0004] The utility model is realized through the following technical solutions:

[0005] The winding and feeding device for a decorative paper printing machine includes a frame 1 and a winding roll 2 mounted on the frame 1. Next to the winding roll 2, a first guide roller 3 and a feeding pressure roller 4 are also cooperatively provided. Both ends of the first guide roller 3 and the feeding pressure roller 4 are mounted on two moving plates 5 symmetrically and slidably arranged on both sides of the frame 1 through bearings. On the frame 1 and next to the two moving plates 5, guiding slide rails 6 are provided to facilitate the moving plates 5 to carry the feeding pressure roller 4 to smoothly approach or move away from the winding roll 2.

[0006] At the rear ends of the two moving plates 5, a moving support plate 7 that can slide along the guiding slide rail 6 is provided. Between the two moving support plates 7, a first synchronous shaft 8 mounted on the frame 1 and capable of driving the two moving support plates 7 to move synchronously is provided. At the bottom of each of the two moving support plates 7, a first rack 7.1 is provided. At both ends of the first synchronous shaft 8, first gears 8.1 that can be meshed and cooperated with the first rack 7.1 are provided. The first synchronous shaft 8 is driven to rotate by a moving motor 9 to enable it to carry the two moving support plates 7 to move left and right along the guiding slide rail 6.

[0007] Between the two moving plates 5, a second synchronous shaft 10 capable of linking the two moving plates 5 to move synchronously is provided; on one of the moving support plates 7, a pressure cylinder 11 is provided, and the movable end of the pressure cylinder 11 is fixedly connected to the rear end of the moving plate 5 located in front of it.

[0008] The pressing air cylinder 11 is preset with a distal position of the movable rod away from the winding reel and a proximal position of the movable rod close to the winding reel. A position detection sensor for detecting the position of the movable rod is further provided in the pressing air cylinder 11, and the position detection sensor is communicatively connected to the controller of the moving motor 9. Thus, when the position detection sensor detects that the position of the movable rod is at the preset distal position, the controller controls the moving motor 9 to rotate, driving the moving support plate 7 to move backward until the movable rod in the pressing air cylinder 11 is at the preset proximal position, thereby realizing the step-by-step backward movement of the feeding and pressing roller 4 so that it can continuously press the winding reel 2 while adapting to the continuously increasing diameter of the winding reel 2.

[0009] Preferably, the second synchronizing shaft 10 is arranged between two moving support plates 7. A second rack 5.1 is provided at the bottom of each of the two moving plates 5. Second gears 10.1 capable of meshing with the second rack 5.1 are provided at both ends of the second synchronizing shaft 10. Thus, through the second synchronizing shaft, the two moving plates 5 can be linked to move synchronously and stably.

[0010] Preferably, a second guide roller 12 for cooperating with the first guide roller 3 for guiding the material is further arranged between the two moving support plates 7.

[0011] Preferably, both the first guide roller 3 and the feeding and pressing roller 4 are rubber rollers.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The winding and feeding device of the decorative paper printing machine of the present utility model has a clever structure. By arranging a pressing air cylinder at the rear end of the feeding and pressing roller, the pressure of the feeding and pressing roller on the winding reel can be adjusted according to the actual winding needs of the material, enabling the types of materials that the printing machine can wind to be diversified while ensuring the winding quality. In addition, the thrust of the pressing air cylinder is used to maintain the continuous pressure of the feeding and pressing roller on the surface of the winding reel. At the same time, the position detection sensor detects the position of the movable rod in the pressing air cylinder to timely discover the state where the feeding and pressing roller is squeezed by the winding reel with an increasing diameter during the winding process. When the movable rod reaches the distal limit position, the moving motor drives the two moving support plates to move backward synchronously until the movable rod in the pressing air cylinder is again at the proximal limit position. Thus, the pressure of the feeding and pressing roller squeezed by the winding reel can be flexibly adjusted to keep the pressure relatively stable, thereby realizing both good pressing of the winding reel and orderly backward movement to adapt to the continuously increasing diameter of the winding reel, ensuring the winding quality well, with strong practicability and worthy of promotion.

[0019] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0020] As Figures 1-3 shown, the rewinding and feeding device of the decorative paper printing machine includes a frame 1 and a winding reel 2 mounted on the frame 1. Next to the winding reel 2, a first guide roller 3 and a feeding and pressing roller 4 are also cooperatively provided. Both ends of the first guide roller 3 and the feeding and pressing roller 4 are mounted on two moving plates 5 symmetrically and slidably arranged on both sides of the frame 1 through bearings. On the frame 1 and next to the two moving plates 5, guide slide rails 6 are provided to facilitate the moving plates 5 to carry the feeding and pressing roller 4 to smoothly approach or move away from the winding reel 2;

[0021] At the rear ends of the two moving plates 5, a moving support plate 7 that can slide along the guide slide rail 6 is provided. Between the two moving support plates 7, a first synchronizing shaft 8 mounted on the frame 1 and capable of driving the two moving support plates 7 to move synchronously is provided. At the bottoms of the two moving support plates 7, a first rack 7.1 is provided. At both ends of the first synchronizing shaft 8, first gears 8.1 that can mesh and cooperate with the first rack 7.1 are provided. The first synchronizing shaft 8 is driven to rotate by a moving motor 9 to enable it to carry the two moving support plates 7 to move left and right along the guide slide rail 6;

[0022] Between the two moving plates 5, a second synchronizing shaft 10 capable of linking the two moving plates 5 to move synchronously is provided; on one of the moving support plates 7, a pressing cylinder 11 is provided, and the movable end of the pressing cylinder 11 is fixedly connected to the rear end of the moving plate 5 located in front of it;

[0023] A distal position where the movable rod is far from the winding reel and a proximal position where the movable rod is close to the winding reel are preset in the material pressing cylinder 11. A position detection sensor for detecting the position of the movable rod is further arranged in the material pressing cylinder 11, and the position detection sensor is communicatively connected to the controller of the moving motor 9. Thus, when the position detection sensor detects that the position of the movable rod is at the preset distal position, the controller controls the moving motor 9 to rotate, driving the moving support plate 7 to move backward until the movable rod in the material pressing cylinder 11 is at the preset proximal position, thereby realizing the step-by-step retraction of the feeding and material pressing roller 4 so that it can continuously press the winding reel 2 while adapting to the continuously increasing diameter of the winding reel 2.

[0024] The second synchronous shaft 10 is arranged between two moving support plates 7. A second rack 5.1 is provided at the bottom of each of the two moving plates 5. Second gears 10.1 that can be meshed with the second rack 5.1 are provided at both ends of the second synchronous shaft 10. Thus, through the second synchronous shaft, the two moving plates 5 can be linked to move synchronously and smoothly.

[0025] A second guide roller 12 for cooperating with the first guide roller 3 for guiding the material is further arranged between the two moving support plates 7.

[0026] Both the first guide roller 3 and the feeding and material pressing roller 4 are rubber rollers.

[0027] During use, the material enters through the second guide roller 12 and then passes through the first guide roller 3 and the feeding and material pressing roller 4 in sequence and enters the winding reel.

[0028] A distal position where the movable rod is far from the winding reel and a proximal position where the movable rod is close to the winding reel are preset in the material pressing cylinder 11. When the position detection sensor detects that the position of the movable rod is at the preset distal position, the controller controls the moving motor 9 to rotate, driving the moving support plate 7 to move backward until the movable rod in the material pressing cylinder 11 is at the preset proximal position, thereby realizing the step-by-step retraction of the feeding and material pressing roller 4 so that it can continuously press the winding reel 2 while adapting to the continuously increasing diameter of the winding reel 2.

[0029] For the winding and feeding device of the decorative paper printing machine of the present utility model, by arranging the material pressing cylinder 11 at the rear end of the feeding and material pressing roller 4, the pressure of the feeding and material pressing roller 4 on the winding reel 2 can be adjusted according to the actual winding needs of the material, so that the types of materials that the printing machine can wind can be diversified while ensuring the winding quality.

[0030] In addition, the thrust of the blank holding cylinder 11 is used to maintain the continuous pressure of the feeding pressing roller 4 on the surface of the winding reel 2. At the same time, the position detection sensor is used to detect the position of the moving rod in the blank holding cylinder 11, so as to timely discover the state that the feeding pressing roller 4 is extruded by the winding reel 2 with the increasing winding diameter during the winding process. When the moving rod reaches the distal limit position, the two moving support plates 7 are driven by the moving motor 9 to move backward synchronously until the moving rod in the blank holding cylinder 11 is repositioned at the proximal limit position. Thus, the pressure of the feeding pressing roller 4 extruded by the winding reel 2 can be flexibly adjusted to keep the pressure relatively stable, and then it can not only press the winding reel 2 well, but also retreat orderly to adapt to the increasing winding diameter of the winding reel 2, which can well guarantee the winding quality.

[0031] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
