Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to an ink scraping device of a book printing machine. Background Art

[0002] A printing press is a machine for printing text and images. A printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. The embossing mechanism is provided with an embossing roller. During the working process of the embossing roller, the embossing roller is coated with ink, and then printed on paper or other substrates through the embossing roller. When the embossing roller prints on the paper, the ink on the embossing roller needs to be evenly coated, otherwise it will affect the printing quality of the paper. At present, a doctor blade is used to scrape the ink on the embossing roller to make the ink evenly coated. The doctor blade is fixedly installed on the printing press.

[0003] After searching, the utility model with announcement number CN218020785U belongs to the technical field of ink scraping device of printing machine, specifically, it is an ink scraping device of printing press embossing roller, including a U-shaped plate; a scraping plate is arranged on the U-shaped plate, a disassembly and assembly mechanism is arranged on the U-shaped plate, the scraping plate is mounted on the U-shaped plate through the disassembly and assembly mechanism, and a box is arranged on one side of the U-shaped plate; through the structural design of the disassembly and assembly mechanism, when a lot of ink adheres to the scraping plate and needs to be cleaned, the adjustment mechanism is first controlled so that the scraping plate is not in contact with the embossing roller, the rotary block is rotated, the rotary block drives the threaded column to rotate, the threaded column drives the lifting plate to move in the vertical direction, the lifting plate drives the plug column to leave the plug hole, and the scraping plate can be pulled out of the U-shaped plate. When installing after cleaning, the scraping plate is inserted between the U-limit block and the U-shaped plate, so that one end of the scraping plate is against the limit plate, the rotary block is rotated to insert the plug column into the slot, and the installation is completed, thereby realizing the function of quickly and conveniently disassembling and assembling the scraping plate.

[0004] The ink scraping device also has the following disadvantages during use: when in use, the box is installed on one side of the machine body and the printing roller, and the distance between the scraper and the printing roller is adjusted by a motor. However, due to the reduced space inside the machine body, the space is blocked during the replacement of the scraper, and its cleaning also requires dismantling and cleaning, which makes the use process inconvenient.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 5 , an ink scraping device for a book printing machine, which is used in the field of printing machines, comprises: a machine body 1, an ink cartridge 7 arranged in the machine body 1, and a printing roller 6 arranged in the machine body 1, both sides of the machine body 1 are provided with mounting holes 2, a mounting frame 3 is detachably arranged in the mounting hole 2, a scraper 10 is arranged in the mounting frame 3 and is located at one side of the printing roller 6, and one side of the scraper 10 contacts the printing roller 6 and is used to scrape off excess ink on the printing roller 6;

[0032] A lifting mechanism is provided on the mounting frame 3 and is used to adjust the height of the scraper 10 so that the scraper 10 can be easily disassembled and installed;

[0033] A cleaning mechanism is arranged at the bottom of the scraper 10 and is used in conjunction with the printing roller 6 to clean the ink at the bottom of the scraper 10. The scraper 10 is installed on the mounting frame 3 and then the mounting frame 3 is disassembled from the machine body 1. When the scraper 10 is replaced, it can be taken out together with the mounting frame 3 for replacement, which can improve the replacement rate. The height of the scraper 10 can be adjusted by the lifting mechanism. At the same time, the ink at the bottom of the scraper 10 can be automatically cleaned by the cleaning mechanism during use, which is convenient to use.

[0034] The lifting mechanism includes two first screw rods 13 rotatably arranged on the bottom wall of the mounting frame 3, the outer walls of the two first screw rods 13 are threadedly sleeved with the same lifting frame 14 located in the mounting frame 3, the scraper 10 is detachably arranged in the lifting frame 14, and a rotating shaft 11 is rotatably provided through one side of the mounting frame 3, and the outer walls of the rotating shaft 11 and the first screw rods 13 are fixedly sleeved with meshing gears 12 for adjusting the lifting and moving of the lifting frame 14 from the outside. By rotating the rotating shaft 11 externally, the first screw rods 13 can be driven to rotate through the gear 12, and the rotation of the first screw rods 13 can drive the lifting and moving of the lifting frame 14, thereby driving the scraper 10 to rise and fall and adjust the position of the scraper 10 relative to the printing roller 6, so that it is convenient to adjust, and a transparent glass can be provided on one side of the body 1 to clearly observe the position of the scraper 10.

[0035] A clamping plate 21 is inserted into the lifting frame 14, and the scraper 10 is inserted into the clamping plate 21. A plurality of bolts 15 are provided through threads on the top of the lifting frame 14. The bottom ends of the bolts 15 are in conflict with the clamping plate 21, so that the clamping plate 21 is deformed to fix the scraper 10. By rotating the bolts 15, not only can the clamping plate 21 be fixed in the lifting frame 14, but the clamping plate 21 can also be deformed to clamp the scraper 10, making it easy to install. In addition, the strength of the scraper 10 can be increased by the clamping plate 21, and it will not bend during use.

[0036] The cleaning mechanism includes two rotating seats 18 fixed at the bottom of the lifting frame 14, and a reciprocating screw 19 is rotatably provided between the two rotating seats 18. Waist-shaped holes 20 are provided at both ends of the mounting frame 3, and the reciprocating screw 19 is located in the waist-shaped holes 20. A nut block 22 is slidably provided at the bottom of the lifting frame 14, and the nut block 22 is threadedly sleeved on the reciprocating screw 19. A rubber block 23 in contact with the bottom of the scraper 10 is fixed on one side of the nut block 22. The reciprocating screw 19 is transmission-connected with the printing roller 6 to drive the rubber block 23 to move. When the printing roller 6 rotates, it will drive the reciprocating screw 19 to rotate. The rotation of the reciprocating screw 19 can drive the nut block 22 to move, and the movement of the nut block 22 can drive the rubber block 23 to move, so that the ink at the bottom of the scraper 10 can be cleaned, which can reduce the number of manual cleaning times.

[0037] Example 2

[0038] refer to Figure 2 , Figure 4 and Figure 5, an improvement on the basis of Example 1: a mounting plate 8 is fixedly provided on the top of the ink cartridge 7, at least two inserting strips 9 are fixedly provided on one side of the mounting plate 8, a mounting frame 3 is plugged into the two inserting strips 9, and a portion of the mounting frame 3 exposed outside the machine body 1 is fixedly connected to the machine body 1 via bolts 15. By plugging the mounting frame 3 into the inserting strips 9, not only can the mounting frame 3 be positioned, but also the mounting frame 3 can be conveniently installed in the machine body 1. When replacing the scraper 10, the mounting frame 3 can be pulled out and replaced outside, which can effectively improve the replacement efficiency.

[0039] A rotating disk 4 is fixedly sleeved on the rotating shaft of the printing roller 6, and a tire 5 that contacts the rotating disk 4 is fixedly sleeved on the outer wall of the reciprocating screw 19. The printing roller 6 can drive the reciprocating screw 19 to rotate through the contact between the rotating disk 4 and the tire 5, and the tire 5 can change its diameter by inflation, so that the rotating disk 4 can still contact the tire 5 after the lifting frame 14 is raised and lowered.
