Description

Technical Field

[0001] This utility model relates to the technical field of gravure printing machine auxiliary equipment, specifically to a gravure printing machine anti-ink-splashing device. Background Technology

[0002] In existing gravure printing machines, the ink trough stores ink, and the bottom of the ink roller is immersed in the ink. The bottom of the ink roller can be coated with ink, and as the ink roller rotates, all parts of its side surface rotate into the ink, ensuring that all sides of the roller are coated with ink. When the workpiece comes into contact with the top of the ink roller, printing begins. However, in existing gravure printing machines, the width of the workpiece is smaller than the width of the ink roller, and the workpiece only comes into contact with the middle of the ink roller's side surface. This means that the left and right ends of the ink roller are not printed. The ink on the left and right ends of the ink roller splashes outwards during rotation, potentially causing environmental pollution. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0024] Please see Figure 1-5 This utility model discloses a gravure printing machine anti-splashing ink device for stopping ink splashes at the ends of ink rollers 5. It includes a stop plate 2, mounting parts 1, and connecting parts 3 respectively connected to the stop plate 2 and the mounting parts 1. Two stop plates 2 are symmetrically arranged, each positioned at a predetermined location on the outer side of both ends of the ink roller 5 to stop ink splashes at both ends. Two mounting parts 1 are respectively arranged corresponding to the two stop plates 2, and each mounting part 1 can be connected to two first side plates 41 on the ink trough 4 near the ends of the ink roller 5. Two connecting parts 3 are respectively arranged corresponding to the two stop plates 2, and each connecting part 3 is connected to both stop plates 2 and the two mounting parts 1.

[0025] Here, the ink reservoir 4 includes a base plate, two first side plates 41, and two second side plates 42. The two first side plates 41 are arranged opposite each other, and the two second side plates 42 are arranged opposite each other. The two ends of one second side plate 42 are respectively connected to one side of the two first side plates 41, and the two ends of the other second side plate 42 are respectively connected to the other side of the two first side plates 41. The base plate is connected to the bottom of the two first side plates 41 and the bottom of the two second side plates 42. The base plate, the two first side plates 41, and the two second side plates 42 form a structure for containing ink. The storage cavity has two first side plates 41 and two second side plates 42 with their tops flush. The top of the ink is lower than the top of the first side plates 41. The two first side plates 41 and two second side plates 42 are arranged in parallel. A rotating shaft 6 is connected to the ink roller 5. The left end of the rotating shaft 6 protrudes from one side of the left end of the ink roller 5, and the right end of the rotating shaft 6 protrudes from one side of the right end of the ink roller 5. Two bearings 7 are provided on the top of the two first side plates 41. The left end of the rotating shaft 6 is rotatably connected to one bearing 7, and the right end is rotatably connected to the other bearing 7. The motor is connected to another bearing 7; the output end of the motor is connected to the left or right end of the rotating shaft 6, and the motor drives the rotating shaft 6, thereby driving the ink roller 5; the first part of the ink roller 5 extends into the ink, and the second part is located above the ink. The first part of the ink roller 5 is covered with ink. The length of the ink roller 5 is less than the length of the storage cavity, and the diameter of the bottom surface of the ink roller 5 is less than the width of the storage cavity, so that when the ink roller 5 rotates, ink can be adhered to all parts of the ink roller 5; the work to be printed comes into contact with the top of the ink roller 5, so that the ink roller 5 prints on the work to be printed. The width of the object is less than the length of the ink roller 5, and the object to be printed abuts against the middle of the ink roller 5; the left end of the ink roller 5 protrudes from the left side of the left end of the object to be printed, and the right end of the ink roller 5 protrudes from the right side of the right end of the object to be printed. A stop plate 2 is set at a preset position outside the left end of the ink roller 5. The stop plate 2 stops the ink splashed from the left end of the ink roller 5. Another stop plate 2 is set at a preset position outside the right end of the ink roller 5. The stop plate 2 stops the ink splashed from the right end of the ink roller 5, so as to prevent the ink from splashing to the outside of the ink trough 4 and polluting the environment.

[0026] The stop plate 2 can be an arc-shaped stop plate 2 with an arc that matches the arc of the end of the ink roller 5, and the axis of the stop plate 2 is parallel to the axis of the ink roller 5.

[0027] Specifically, the curvature of the two stop plates 2 matches the curvature of the corresponding ends of the ink rollers 5. That is, the curvature of the stop plate 2 on the left matches the curvature of the left end of the ink roller 5, and the curvature of the stop plate 2 on the right matches the curvature of the right end of the ink roller 5. The axes of the two stop plates 2 are parallel to the axis of the ink roller 5, and the axes of the two stop plates 2 can coincide. The distance between each part of the stop plate 2 on the left and the corresponding part of the left end of the ink roller 5 is the same, and the distance between each part of the stop plate 2 on the right and the corresponding part of the right end of the ink roller 5 is the same. The lowest point of both stop plates 2 is located above the top surface of the ink.

[0028] Mounting component 1 may include mounting plate 11 and fixing block 12. The bottom of mounting plate 11 may be fixedly connected to the first side plate 41. The side of fixing block 12 is connected to the side of mounting plate 11 near ink roller 5. Connecting component 3 is connected to the first part of fixing block 12 and stop plate 2 respectively. The second part of stop plate 2 protrudes from one side of fixing block 12 to stop ink splashing at the end of ink roller 5.

[0029] Specifically, the mounting plate 11 can be welded to the first side plate 41. The mounting plate 11 can also be connected to the first side plate 41 by screws. A third mounting hole matching the bearing 7 is provided through the bottom of the mounting plate 11. When the mounting plate 11 is fixedly connected to the first side plate 41, the bearing 7 connected to the first side plate 41 is inserted into the third mounting hole. The side of the fixing block 12 can be welded to the side of the mounting plate 11 near the ink roller 5. The distance between the side of the fixing block 12 connected to the mounting plate 11 and the other side of the fixing block 12 away from the mounting plate 11 is not greater than the length of the portion of the rotating shaft 6 protruding from one side of the ink roller 5. Similarly, the distance between the side of the fixing block 12 on the right side connected to the mounting plate 11 and the other side of the fixing block 12 away from the mounting plate 11 is not greater than the length of the portion of the rotating shaft 6 protruding from the right end of the ink roller 5. Likewise, the distance between the side of the fixing block 12 on the left side connected to the mounting plate 11 and the other side of the fixing block 12 away from the mounting plate 11 is not greater than the length of the portion of the rotating shaft 6 protruding from the left end of the ink roller 5. The second part of the stop plate 2 protrudes from one side of the fixing block 12. The second part of the stop plate 2 can be located above the end of the ink roller 5, thereby stopping the ink splashed from the end of the ink roller 5.

[0030] The connector 3 may include a threaded part 31, and the fixing block 12 is provided with a threaded groove. The first part of the threaded part 31 is connected to the stop plate 2, and the second part is threaded to the threaded groove.

[0031] Specifically, the threaded part 31 can be a screw. The bottom of the threaded part 31 is threaded into the threaded groove, and the top of the threaded part 31 can be welded to the bottom surface of the stop plate 2. The top of the threaded part 31 can also be detachably connected to the bottom surface of the stop plate 2.

[0032] The connector 3 may also include a first limiting part 32 and a second limiting part 33. A first mounting hole is provided through the stop plate 2. The bottom of the screw connection part 31 passes through the first mounting hole and is screwed into the threaded groove. The first limiting part 32 is screwed onto the portion of the screw connection part 31 located above the stop plate 2 and abuts against the top surface of the stop plate 2. The second limiting part 33 is screwed onto the portion of the screw connection part 31 located between the stop plate 2 and the fixing block 12 and abuts against the bottom surface of the stop plate 2.

[0033] Specifically, both the first limiting part 32 and the second limiting part 33 can be nuts. First, the first limiting part 32 is screwed onto the first preset part of the screw connection part 31. Then, the bottom of the screw connection part 31 passes through the first mounting hole on the stop plate 2. Next, the second limiting part 33 is screwed onto the second preset part of the screw connection part 31 located below the stop plate 2. At this time, the top surface of the stop plate 2 does not abut against the first limiting part 32, and the bottom surface of the stop plate 2 does not abut against the second limiting part 33. Then, the bottom of the screw connection part 31 is screwed into the threaded groove. Then, the first limiting part 32 and the second limiting part 33 are rotated respectively, so that the first limiting part 32 abuts against the top surface of the stop plate 2, and the second limiting part 33 abuts against the bottom surface of the stop plate 2, thereby fixing the stop plate 2 and the screw connection part 31 and the fixing block 12. The bottom of the screw connection 31 is screwed into the threaded groove at different heights, thereby adjusting the distance between the stop plate 2 and the fixing block 12, and thus adjusting the distance between the stop plate 2 and the top of the ink roller 5.

[0034] The first mounting hole can be a strip-shaped hole with its axis parallel to the axis of the ink roller 5.

[0035] Specifically, by passing the bottom of the screw connection 31 through different positions within the first mounting hole, the distance between the side of the stop plate 2 near the mounting plate 11 and the mounting plate 11 can be adjusted, the width of the portion of the stop plate 2 protruding from the side of the fixing block 12 can be adjusted, and the area of ​​the portion of the stop plate 2 protruding from the side of the fixing block 12 can be adjusted to better stop the ink splashing on the ink roller 5.

[0036] The connector 3 may also include a handle 34 connected to the top of the screw connection 31.

[0037] Specifically, by turning the handle 34, the screw connection 31 can be rotated, thereby allowing adjustment of the screw connection 31.

[0038] There can be multiple threaded grooves, multiple first mounting holes corresponding to the multiple threaded grooves, multiple threaded connection parts 31 corresponding to the multiple first mounting holes, multiple first limiting parts 32 corresponding to the multiple threaded connection parts 31, and multiple second limiting parts 33 corresponding to the multiple threaded connection parts 31.

[0039] Specifically, multiple threaded grooves can be symmetrically arranged, multiple first mounting holes can be symmetrically arranged, and multiple threaded connections 31 can be symmetrically arranged. There can be two threaded grooves, two first mounting holes, two threaded connections 31, two first limiting parts 32, and two second limiting parts 33.

[0040] The mounting plate 11 may have a second mounting hole 111 through which the stop plate 2 can pass when it moves in a direction parallel to the axis of the ink roller 5.

[0041] Specifically, the shape of the second mounting hole 111 can match the shape of the stop plate 2, allowing the stop plate 2 to pass through the second mounting hole 111. A portion of the stop plate 2 is disposed on one side of the mounting plate 11, and the other portion of the stop plate 2 passes through the second mounting plate 11 and is connected to the screw connection 31, the first limiting portion 32, and the second limiting portion 33 respectively. By passing different positions on the stop plate 2 through the second mounting hole 111, the width of the portion of the stop plate 2 connected to the screw connection 31 can be adjusted, thereby adjusting the width of the portion of the stop plate 2 protruding from one side of the fixing block 12 and adjusting the area of ​​the portion of the stop plate 2 protruding from one side of the fixing block 12, thus better stopping the ink splashing from the end of the ink roller 5.

[0042] Mounting component 1 may also include a limiting block disposed on the top surface of fixing block 12. The limiting block is used to limit the stop plate 2 when the screwed part 31 is screwed into the threaded groove at different positions and drives the stop plate 2 to move downward.

[0043] Specifically, the bottom of the screw connection 31 is screwed into the threaded groove at different heights, and the stop plate 2 is moved toward the top surface of the fixing block 12. The first limiting part 32 and the second limiting part 33 are respectively connected to the screw connection 31, thereby fixing the stop plate 2. During the process of the stop plate 2 moving toward the top surface of the fixing block 12, the limiting block can limit the stop plate 2 to avoid the distance between the stop plate 2 and the top surface of the ink roller 5 being too small, which would affect the printing process of the material to be printed.

[0044] The connector 3 also includes an abutment plate 35 disposed above the stop plate 2. The bottom surface of the abutment plate 35 abuts against the top surface of the stop plate 2. A third mounting hole corresponding to the first mounting hole is provided through the abutment plate 35. The bottom of the screw connection part 31 passes through the third mounting hole and the first mounting hole in sequence and is screwed into the threaded groove. The first limiting part 32 is screwed onto the portion of the screw connection part 31 located above the abutment plate 35. The bottom of the first limiting part 32 abuts against the top surface of the abutment plate 35. The second limiting part 33 is screwed onto the portion of the screw connection part 31 located between the stop plate 2 and the fixing block 12. The top of the second limiting part 33 abuts against the bottom surface of the stop plate 2.
