Description

Technical Field

[0001] The present application relates to the field of printing presses, and in particular to a feeding deviation rectifying mechanism for a printing press. Background Art

[0002] With the rise of online shopping, the traditional carton business has also regained new vitality. For the express delivery sent to customers, the first thing that is often noticed is the external carton. Therefore, many merchants will choose to print their own trademark patterns on the cartons. A carton printing press is a printing device that can print the required text, patterns, and other information on the surface of the carton body. In order to ensure the printing quality, the cartons need to be arranged neatly and then fed into the printing press. However, the sizes of different cartons are different. Therefore, the deviation rectifying mechanism needs to be adjusted little by little according to the size of the carton.

[0003] Regarding the above related technologies, the inventor believes that the common feeding deviation rectifying mechanism of a printing press has the defect of being difficult to quickly adjust the position according to the size of the carton. Since the deviation rectifying mechanism needs to be consistent with the size of the carton, the adjustment of the deviation rectifying mechanism is usually relatively precise, which results in a slow adjustment speed and affects the printing efficiency of cartons of different sizes. Therefore, a feeding deviation rectifying mechanism for a printing press is proposed to solve the above problems.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior arts that are not known to those of ordinary skill in the art. Utility Model Content

[0005] In order to solve the problem that the common feeding deviation rectifying mechanism of a printing press is difficult to quickly adjust the position according to the size of the carton, the present application provides a feeding deviation rectifying mechanism for a printing press.

[0006] The feeding deviation rectifying mechanism for a printing press provided by the present application adopts the following technical solution:

[0007] A feeding deviation rectifying mechanism for a printing press includes a printing press body. An inlet table is installed on the printing press body. Two parallel movement grooves are opened on the inlet table. Two movement rods are respectively installed in the two movement grooves. A translation block is installed on the tops of the two movement rods. A fixing component is installed on the side wall of the translation block. A micro-movement component is also installed on the top wall of the translation block. A scale line is installed on the top wall of the inlet table.

[0008] Preferably, the starting position of the scale line is set in the middle, and the two translation blocks are respectively located on both sides of the starting position of the scale line.

[0009] Preferably, the fixing component includes a connecting rod and two clamping blocks. A plurality of limiting grooves are formed in the side wall of the movement groove. Two through holes are formed in the top wall of the translation block. The sizes of the through holes are the same as those of the limiting grooves. The two clamping blocks are respectively located in the two through holes. The two ends of the connecting rod are fixedly connected to the top walls of the two clamping blocks.

[0010] Preferably, the fine movement component includes a hand wheel, a fixing block, a screw rod and a rectifying plate. The fixing block is arranged on the top wall of the translation block. A threaded hole is formed in the side wall of the fixing block. The screw rod is in threaded connection with the threaded hole. The hand wheel is arranged at one end of the screw rod. The rectifying plate is rotatably connected to the other end of the screw rod. The bottom wall of the rectifying plate abuts against the top wall of the feeding table.

[0011] Preferably, one end of the rectifying plate away from the printing machine body is designed to be arc-shaped.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] The position of each limiting groove is aligned with the integer scale of the scale line. Therefore, when the rectifying plate needs to be quickly moved, the two clamping blocks can be lifted by the connecting rod, and then the translation block is horizontally moved until the translation block moves to the integer scale position. Then, the clamping blocks can be lowered to fix the position of the translation block. Then, the position of the rectifying plate is finely adjusted by using the hand wheel, so that the rectifying plate can be consistent with the size of the carton, thereby rectifying cartons of different sizes.

Detailed Description of the Embodiment

[0018] The following further describes the present application in detail Figures 1-3 with reference to the attached drawings.

[0019] The embodiment of the present application discloses a feeding rectifying mechanism of a printing machine. Refer to Figure 1, a feeding deviation rectifying mechanism for a printing press, comprising a printing press body 1, a feeding table 2 is installed on the printing press body 1, two parallel movement grooves 3 are opened on the feeding table 2, two movement rods 4 are respectively installed in the two movement grooves 3, and two movement rods 4 The top is provided with a translation block 5. The two movement rods 4 enable the translation block 5 to slide stably on the surface of the feeding table 2, thereby ensuring that the deviation rectifying plate 14 can perform deviation rectification stably;

[0020] Refer to Figure 3 , a fixing component is installed on the side wall of the translation block 5. The fixing component includes a connecting rod 7 and two clamping blocks 8. A number of limiting grooves 9 are opened on the side wall of the movement groove 3, and two through holes 10 are opened on the top wall of the translation block 5. The size of the through hole 10 is the same as that of the limiting groove 9. The two clamping blocks 8 are respectively located in the two through holes 10. The two ends of the connecting rod 7 are fixedly connected to the top walls of the two clamping blocks 8. The position of the limiting groove 9 is aligned with the integer scale of the scale line 6. Therefore, after knowing the size of the carton, the staff can quickly move the deviation rectifying plate 14 to the approximate position, which is convenient for fine-tuning in the later stage;

[0021] Refer to Figure 2 , a fine movement component is also installed on the top wall of the translation block 5. The fine movement component includes a handwheel 11, a fixed block 12, a screw rod 13 and a deviation rectifying plate 14. The fixed block 12 is installed on the top wall of the translation block 5. A threaded hole 15 is opened on the side wall of the fixed block 12. The screw rod 13 is threadedly connected to the threaded hole 15. The handwheel 11 is installed at one end of the screw rod 13. The deviation rectifying plate 14 is rotatably connected to the other end of the screw rod 13. The bottom wall of the deviation rectifying plate 14 abuts against the top wall of the feeding table 2. One end of the deviation rectifying plate 14 away from the printing press body 1 is designed to be arc-shaped. The arc-shaped design is more convenient for the carton to enter the printing press body 1, and it is also more convenient for the deviation rectifying plate 14 to guide the carton to move to a vertical state;

[0022] A scale line 6 is installed on the top wall of the feeding table 2. The starting position of the scale line 6 is set in the middle. The two translation blocks 5 are respectively located on both sides of the starting position of the scale line 6. The readings of the scale line 6 increase from the middle to both sides in turn. The two translation blocks 5 are respectively located on two identical readings.

[0023] The implementation principle of the feeding deviation rectifying mechanism of a printing press in the embodiment of the present application is as follows: First, roughly adjust the position of the deviation rectifying plate 14 according to the size of the carton. Lift the connecting rod 7 and the clamping block 8 upward to make them leave the through hole 10, and then move the translation block 5 horizontally, so that the movement rod 4 slides in the movement groove 3. When sliding to the approximate integer position, put the clamping block 8 down so that it is stuck in the limiting groove 9. Then the staff can rotate the handwheel 11 to make the screw rod 13 advance in the threaded hole 15, so that the deviation rectifying plate 14 moves to the specified position, which is convenient for rectifying the deviation of the carton.
