Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulating devices, and specifically to a printing roller pressure regulating device. Background Art

[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, 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 a printing press. Then, ink is applied to the places with text and images on the printing plate by hand or by 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 printed products identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] In the prior art, when a printing press is used for printing, since the thickness of the articles to be printed is different during printing, the printing roller on the printing press needs to be adjusted all the time during printing to adapt to the thickness of the printed articles with different thicknesses. However, the traditional way of adjusting the printing roller is to use manual adjustment. This adjustment method is not only slow, but also the height of the adjustment is estimated and debugged based on the experience of the staff. It is not only not accurate enough, but also causes the heights on both sides of the printing roller to be different, thereby causing printing failure. Therefore, a printing roller pressure adjustment device is needed to meet people's needs. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0031] A U-shaped plate 2 is installed on the workbench 1, a rotating shaft 3 is rotatably installed on the U-shaped plate 2, and a driving motor 4 is installed on one side of the rotating shaft 3;

[0032] In order to facilitate the printing roller 52 to be used for different items to be printed, a lifting structure is arranged on the U-shaped plate 2, specifically including two sliding blocks 5, both of which are slidably installed on the U-shaped plate 2, and the two sliding blocks 5 are rotatably installed with a rotating shaft 51, and the printing roller 52 is sleeved on the rotating shaft 51, and the printing roller 52 is adapted to the rotating shaft 3. A first servo motor 53 is installed on the driving structure, and a first driving shaft 54 ​​is installed on the first servo motor 53. A transmission assembly 55 is sleeved on the first driving shaft 54, and the other end of the transmission assembly 55 is sleeved on the rotating shaft 51. The U-shaped plate 2 is provided with a scale line 57, and an indicator arrow 56 is installed on the sliding block 5, and the indicator arrow 56 is adapted to the scale line 57. The rotating shaft 51 slides on the U-shaped plate 2, so that the printing roller 52 can move up and down, and will not deviate during movement. At the same time, by using the setting of the indicator arrow 56 and the scale line 57, the printing roller 52 can be accurately moved to a position suitable for the item to be printed.

[0033] In order to provide power for the up and down movement of the printing roller 52, a driving structure is arranged on the rotating shaft 51, specifically including two second servo motors 6, both of which are mounted on the U-shaped plate 2, a second driving shaft 61 is mounted on the second servo motor 6, a transmission plate 62 is mounted on the second driving shaft 61, an adapter plate 63 is slidably mounted on the transmission plate 62, a connecting plate 66 is mounted on the bottom side of the adapter plate 63, and the connecting plate 66 is sleeved on the rotating shaft 51, a moving shaft 64 is mounted on the transmission plate 62, and a connecting plate 66 is mounted on the bottom side of the adapter plate 63. A sliding hole 65 is provided, and the movable shaft 64 is slidably installed in the sliding hole 65. The switch on the second servo motor 6 is started, and the second servo motor 6 is used to drive the second driving shaft 61 to rotate, and the second driving shaft 61 drives the transmission plate 62 to rotate, and the transmission plate 62 drives the movable shaft 64 to slide on the adapter plate 63, so that the adapter plate 63 can be conveniently driven to reciprocate up and down in the vertical direction. At the same time, the adapter plate 63 drives the connecting plate 66 to move, and the connecting plate 66 drives the printing roller 52 on the rotating shaft 51 to reciprocate up and down in the vertical direction.

[0034] Embodiment 2:

[0035] On the basis of Example 1, in order to provide a buffering effect when the printing roller 52 approaches the rotating shaft 3, a buffering structure is arranged on the printing roller 52, specifically including two fixed blocks 7, the two fixed blocks 7 are respectively installed on the two rotating shafts 51, a buffer spring 72 is installed on the bottom side of the fixed block 7, and a retaining block 73 is installed on the other end of the buffer spring 72, the retaining block 73 is installed on the U-shaped plate 2 and is rotatably connected to the rotating shaft 3, a telescopic rod 71 is sleeved on the buffer spring 72, one end of the telescopic rod 71 is installed on the fixed block 7, and the other end of the telescopic rod 71 is installed on the retaining block 73. When the printing roller 52 is at the highest point The buffer spring 72 is in a stretched state. When the printing roller 52 approaches the rotating shaft 3, the printing roller 52 drives the fixed block 7 to move downward, and the fixed block 7 drives the buffer spring 72 to be compressed. At this time, the tension of the buffer spring 72 can effectively prevent the printing roller 52 from colliding with the rotating shaft 3 when it moves too fast toward the rotating shaft 3, and the movement of the printing roller 52 is started to buffer. At the same time, when the printing roller 52 moves downward, the fixed block 7 will drive the telescopic rod 71 to contract, and at the same time, it can effectively limit the retaining block 73 to only move in the vertical direction when contracting or stretching, and there will be no deviation. The remaining features are the same as those in Example 1.

[0036] Working principle:

[0037] When the printing roller 52 on the workbench 1 is used to print the to-be-printed article, in order to facilitate the printing roller 52 to be suitable for printing the to-be-printed articles of different thicknesses, when in use, the switch on the driving motor 4 is first started, and the driving motor 4 is used to drive the rotating shaft 3 to rotate on the U-shaped plate 2, and at the same time, the first servo motor 53 on the connecting plate 66 is started, and the first servo motor 53 is used to drive the first driving shaft 54 ​​to rotate, and the first driving shaft 54 ​​drives the transmission assembly 55 to rotate, and the transmission assembly 55 drives the rotating shaft 51 to rotate on the U-shaped plate 2, so that the printed article can be printed conveniently;

[0038] Next, when it is necessary to move the position of the printing roller 52, the switch on the second servo motor 6 is started, and the second servo motor 6 is used to drive the second drive shaft 61 to rotate, and the second drive shaft 61 drives the transmission plate 62 to rotate, and the transmission plate 62 drives the moving shaft 64 to slide on the adapter plate 63, so that the adapter plate 63 can be conveniently driven to reciprocate up and down in the vertical direction. At the same time, the adapter plate 63 drives the connecting plate 66 to move, and the connecting plate 66 drives the rotating shaft 51 to move in the vertical direction. The rotating shaft 51 drives the sliding block 5 to move, and the sliding block 5 drives the printing roller 52 to reciprocate up and down in the vertical direction. At the same time, when the sliding block 5 moves, the indicating arrow 56 on the sliding block 5 will always point to the scale line 57, so that the printing roller 52 can be conveniently, accurately and quickly moved to a suitable position for use;

[0039] Since the buffer spring 72 is in a stretched state when the printing roller 52 is at the highest point, when the printing roller 52 approaches the rotating shaft 3, the printing roller 52 drives the fixed block 7 to move downward, and the fixed block 7 drives the buffer spring 72 to be compressed. At this time, the tension of the buffer spring 72 can effectively prevent the printing roller 52 from colliding with the rotating shaft 3 when it moves too fast toward the rotating shaft 3, and the movement of the printing roller 52 is activated to buffer the movement. At the same time, when the printing roller 52 moves downward, the fixed block 7 will drive the telescopic rod 71 to contract, and at the same time, it can effectively limit the retaining block 73 to only move in the vertical direction when contracting or stretching, and no deviation will occur.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
