Description

Technical Field

[0001] The invention belongs to the technical field of web printing presses, and in particular relates to an inking mechanism with follow-up and self-channeling functions. Background Art

[0002] There are many structures of inking devices in existing web-fed printing presses. The inking roller is usually fixed on the inking roller frame at both ends, and the pressure adjustment end of the inking roller is in the form of an eccentric sleeve or a long hole, which is tightened after adjustment. The clutch of the inking roller and the plate cylinder is usually driven by a cylinder to drive the connecting rod, and the connecting rod drives the inking roller frame, thereby driving the clutch of the inking roller, and the pressure is usually adjusted by screws.

[0003] However, there are two problems in the actual use of the existing inking mechanism. The first problem is that after the pressures on the transmission side and the operating side of the inking mechanism are adjusted, the pressures at both ends of the inking roller in contact with the printing plate cylinder will be inconsistent after the printing plate cylinder is tilted. If the pressure value changes too much, it will affect the printing quality. The second problem is that the existing structure of the inking roller can only rotate and is usually unable to move in the axial direction. Sometimes "ghost images" will appear on the printing plate. The graphic elements are superimposed on the graphic area that follows along the printing direction. This is called "ghost images". This is a printing problem, and the existing inking roller cannot eliminate the "ghost image" problem. Summary of the invention

The follower unit is connected to the driving unit. When the eccentric sleeve for adjusting the inclination is adjusted, the driving unit moves along with the follower unit, thereby driving the connected inking roller frame to drive the inking roller to perform follow-up adjustment.

[0006] The present invention is also characterized in that Both ends of the first inking roller and the third inking roller are equipped with bearing inner rings and locking blocks, the eccentric sleeve is located between the locking block and the inking roller frame, and the axial movement distance of the inking roller is equal to the spacing between the locking block and the eccentric sleeve.

[0007] The eccentric sleeve is provided with a set screw b.

[0008] The inking roller frame includes a first inking roller frame, a second inking roller frame and a third inking roller frame. The first inking roller frame, the second inking roller frame and the third inking roller frame are symmetrically located at both ends of the corresponding inking rollers. The inking roller frame is movably connected with a clamping block a and a clamping block b for fixing the inking roller, and a set screw a is provided on the clamping block a and the clamping block b.

When the third inking roller frame is pushed by force, it rotates around the axis of the second inking roller.

When the slant-adjusting eccentric sleeve adjusts the printing plate cylinder, the first follow-up connecting rod and the second follow-up connecting rod respectively drive the eccentric swing seat and the swing rod c to swing slightly, thereby realizing the slight swing of the swing rod a and the swing rod b. Since the swing rod a and the swing rod b are respectively connected to the first inking roller frame, the second inking roller frame and the third inking roller frame through the first connecting rod, the second connecting rod and the third connecting rod, the first inking roller, the second inking roller and the third inking roller are synchronously driven to perform follow-up adjustment, that is, the pressure between the inking roller and the printing plate cylinder can follow the slant adjustment of the printing plate cylinder. When the printing plate cylinder is slanted, the pressure between the inking roller and the printing plate cylinder does not need to be adjusted, the amount of ink applied is uniform and unchanged, and the unstable quality of the printed product caused by the adjustment of the ink amount is reduced.

[0014] (2) The inking mechanism with follow-up and self-moving functions of the present invention provides the inking roller with axial displacement capability by arranging linear bearings at both ends of the inking roller, and controls the axial self-movement amount of the inking roller by arranging a locking block.

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The inking mechanism with follow-up and self-strapping functions of the present invention is composed of an inking roller, an inking roller frame, a cylinder, a connecting rod, a swing rod and various adjustment mechanisms. There are three inking rollers, namely the first inking roller 1, the second inking roller 2 and the third inking roller 3. Each inking roller is installed on its own inking roller frame. The cylinder is connected to the inking roller frame through a swing rod and a connecting rod to control the clutch of the inking roller and the plate cylinder 25. The pressure of the two can be adjusted by adjusting the length of the connecting rod. The pressure of the inking roller and the inking roller is adjusted by adjusting the eccentric sleeve installed on the inking roller shaft head and locked. The axial self-strapping of the inking roller is achieved by the linear movement of the linear bearing.

[0020] Example 1 The inking mechanism of the present invention has the following and self-contained functions, such as Figure 1 and Figure 2 As shown, it includes a first inking roller 1, a second inking roller 8 and a third inking roller 15. Eccentric sleeves 27 are symmetrically installed at both ends of the first inking roller 1 and the third inking roller 15. A linear bearing 28 is fixed inside the eccentric sleeve 27. Both ends of the first inking roller 1 and the third inking roller 15 are respectively fixed to the corresponding inking roller frames through the eccentric sleeves 27, and the second inking roller 8 is directly fixedly connected to the corresponding inking roller frame.

[0021] Furthermore, the inking roller frame includes a first inking roller frame 2, a second inking roller frame 9 and a third inking roller frame 16, and the first inking roller frame 2, the second inking roller frame 9 and the third inking roller frame 16 are symmetrically located at two ends of the corresponding inking rollers.

[0022] The first ink roller 18 and the second ink roller 19 are also included to drive the ink roller to move axially, and the ink roller frame is movably connected with the corresponding ink roller. Specifically, the first ink roller frame 2 and the second ink roller frame 9 are movably connected with the first ink roller 18, and when the first ink roller frame 2 and the second ink roller frame 9 are pushed by force, they rotate around the axis of the first ink roller 18; the third ink roller frame 16 is movably connected with the second ink roller 19, and when the third ink roller frame 16 is pushed by force, it rotates around the axis of the second ink roller 19.

[0023] That is, the first inking roller 1 and the second inking roller 8 are in contact with the first inking roller 18, and the movement of the first inking roller 18 drives the first inking roller 1 to move axially. The third inking roller 15 is in contact with the second inking roller 19, and the movement of the second inking roller 19 drives the third inking roller 15 to move axially, thereby avoiding printing problems such as ink bars and "ghost images" generated during the printing process.

[0024] Furthermore, the first inking roller 1 and the third inking roller 15 are both provided with a bearing inner ring 29 and a locking block 31 at both ends, the eccentric sleeve 27 is located between the locking block 31 and the inking roller frame, and the distance of the axial movement of the inking roller is equal to the distance between the locking block 31 and the eccentric sleeve 27. That is, the self-movement amount of the inking roller is the gap between the locking block 31 and the eccentric sleeve 27.

[0025] Furthermore, a set screw b30 is provided on the eccentric sleeve 27. Loosening the set screw b30 and rotating the eccentric sleeve 27 can adjust the distance between the ink roller and the corresponding ink-stirring roller, thereby adjusting the pressure between the two. The operating surface and the transmission surface need to be adjusted at the same time to ensure that the pressure on both sides is consistent. At the same time, a scale is engraved on the eccentric sleeve 27 to ensure that the pressure on both sides is consistent when the same value is adjusted.

[0026] The first inking roller frame 2, the second inking roller frame 9 and the third inking roller frame 16 are also respectively connected to a driving unit for adjusting the distance between the inking roller and the plate cylinder 25; It also includes an eccentric sleeve 26 for adjusting the inclination installed on one side of the wall of the operating surface. The eccentric sleeve 26 is movably connected to the plate cylinder 25. A follower unit is connected to the eccentric sleeve 26. The follower unit is connected to the driving unit. When the eccentric sleeve 26 is adjusted, the driving unit moves with the follower unit, thereby driving the connected inking roller frame to drive the inking roller to perform follow-up adjustment.

[0027] Example 2 On the basis of Example 1, the driving unit of the inking mechanism with follow-up and self-moving functions of the present invention comprises a first connecting rod 3 connected to the first inking roller frame 2, the other end of the first connecting rod 3 is connected to a swing rod a4, the swing rod a4 is fixedly connected to a first rotating shaft 5, the first rotating shaft 5 is movably connected to the operating surface wall and the transmission surface wall, and the first rotating shaft 5 is connected to a first cylinder 7 through the wall at one end opposite to the operating surface wall; Figure 3 and Figure 4 As shown, it also includes a second connecting rod 10 connected to the second inking roller frame 9, and the other ends of the second connecting rod 10 on both sides are respectively connected to the rocker arm b12 and the rocker arm d36, the rocker arm b12 is movably connected to the eccentric shaft 11, the eccentric shaft 11 is movably connected to the operating surface wall, the rocker arm d36 is movably connected to the transmission shaft 35, and the transmission shaft 35 is fixedly connected to the transmission surface wall. Specifically, bearings are arranged on the inner sides of the rocker arm b12 and the rocker arm d36, which are respectively sleeved on the outer sides of the eccentric shaft 11 and the transmission shaft 35, so as to realize relative rotation between the rocker arm and the shaft body.

[0028] Furthermore, the rocker rod b12 and the rocker rod d36 are also connected to the second cylinder 13 respectively.

[0029] It also includes a third connecting rod 17 connected to the third inking roller frame 16, and the other ends of the third connecting rod 17 on both sides are respectively connected to the swing rod b12 and the swing rod d36.

[0030] Furthermore, the lengths of the first connecting rod 3, the second connecting rod 10, and the third connecting rod 17 can be freely adjusted and fixed. After being pressed together, the axis of the first rotating shaft 5 and the connection point of the first connecting rod 3 and the rocker arm a4 and the connection point of the first connecting rod 3 and the first inking roller frame 2 are in the same straight line and are located on the same side of the first inking roller 1.

[0031] Similarly, after pressing, the axis center of the connection between the eccentric shaft 11 and the rocker arm b12 is located in the same straight line as the connection point between the second connecting rod 10 and the rocker arm b12 and the connection point between the second connecting rod 10 and the second ink roller frame 9, and is located on the same side of the second ink roller 8; at the same time, the axis center of the connection between the eccentric shaft 11 and the rocker arm b12 is also located in the same straight line as the connection point between the third connecting rod 17 and the rocker arm b12 and the connection point between the third connecting rod 17 and the third ink roller frame 16, and the straight line formed by the three points is located on the same side of the third ink roller 15.

[0032] The second connecting rod 10 and the third connecting rod 17 on the transmission shaft 35 side are in the same state after being pressed, that is, the axis center of the connection between the transmission shaft 35 and the rocker arm d36, the connection point between the second connecting rod 10 and the rocker arm d36, and the connection point between the second connecting rod 10 and the second inking roller frame 9 are located in the same straight line, and the axis center of the connection between the transmission shaft 35 and the rocker arm d36 is also located in the same straight line with the connection point between the third connecting rod 17 and the rocker arm d36, and the connection point between the third connecting rod 17 and the third inking roller frame 16.

[0033] Furthermore, the first cylinder 7 is connected to a transmission rocker arm 6, which is fixed to one end of the first rotating shaft 5 passing through the operating surface wall, and the first cylinder 7 and the second cylinder 13 are fixed to the operating surface wall by bolts.

[0034] That is, when the distance between the first ink roller 1 and the plate cylinder 25 needs to be adjusted, the transmission swing rod 6 is driven to swing by the first cylinder 7. Since the transmission swing rod 6 is fixedly connected to the first rotating shaft 5, it drives the first rotating shaft 5 to rotate, thereby realizing the synchronous swing of the swing rod a4. When the swing rod a4 swings, under the action of the first connecting rod 3, the first ink roller frame 2 rotates around the axis of the first ink roller 18, so that the first ink roller frame 2 brings the first ink roller 1 close to the plate cylinder 25 or away from the plate cylinder 25. The principle of adjusting the distance between the second ink roller 8 and the third ink roller 15 and the plate cylinder 25 is the same as above, and the only difference is that the second cylinder 13 drives the swing rod b12 and the swing rod d36 to swing to achieve the distance adjustment.

[0035] like Figure 5 As shown, the ink roller frame is movably connected with a clamping block a20 and a clamping block b22 for fixing the ink roller, and a set screw a24 is provided on the clamping block a20 and the clamping block b22. When the ink roller needs to be disassembled and replaced, the set screws 24 are loosened at both ends of the ink roller, and the clamping block b22 is rotated clockwise around the pin shaft b23, and the clamping block a20 is rotated counterclockwise around the pin shaft a21, so that the ink roller to be replaced can be quickly and conveniently removed.

[0036] Example 3 On the basis of Example 2, Figure 6 As shown, the follow-up unit in the inking mechanism with follow-up and self-flowing functions of the present invention includes a first follow-up connecting rod 32 and a second follow-up connecting rod 33 respectively connected to the tilt adjusting eccentric sleeve 26; the end of the first follow-up connecting rod 32 away from the tilt adjusting eccentric sleeve 26 is connected to an eccentric pendulum seat 34, the eccentric pendulum seat 34 is installed on the wall of the operating surface, and the first rotating shaft 5 passes through the inner side of the eccentric pendulum seat 34 and is movably connected to the eccentric pendulum seat 34, and the end of the second follow-up connecting rod 33 away from the tilt adjusting eccentric sleeve 26 is connected to a pendulum rod c14, and the pendulum rod c14 is fixedly connected to the eccentric shaft 11.

[0037] Furthermore, the swing rod c14 and the swing rod b12 are connected to different shafts on the eccentric shaft 11, such as Figure 3 As shown, the rocker rod c14 is located on the eccentric shaft 11 outside the operating surface, and the rocker rod b12 is located on the eccentric shaft 11 between the operating surface and the transmission surface. Since the eccentric shaft 11 is an eccentric shaft, when the rocker rod c14 drives one end of the shaft body of the eccentric shaft 11 to rotate, the other end of the shaft body will swing eccentrically, thereby driving the rocker rod b12 on the shaft body to swing.

[0038] Furthermore, the first follower link 32 and the second follower link 33 may be connected to a printing plate tilting mechanism for adjusting the tilt of the printing plate cylinder 25 .

[0039] When the printing plate cylinder 25 needs to be tilted, the tilting eccentric sleeve 26 on the printing plate cylinder 25 is driven to rotate by the worm gear mechanism. Since the tilting eccentric sleeve 26 is only installed on the operating side, when the tilting eccentric sleeve 26 rotates, the transmission side is not eccentric, thereby realizing the tilting of the printing plate cylinder 25; at this time, the tilting eccentric sleeve 26 drives the eccentric swing seat 34 and the swing rod c14 to rotate respectively through the first follower connecting rod 32 and the second follower connecting rod 33, so that the first rotating shaft 5 and the eccentric shaft 11 have a slight swing on the operating side, and the first rotating shaft 5 and the eccentric shaft 11 can be connected to the shaft The rocker arm a4 and the rocker arm b12 on the body respectively drive the first connecting rod 3, the second connecting rod 10 and the third connecting rod 17 to drive the first inking roller frame 2, the second inking roller frame 9 and the third inking roller frame 16 to slightly rotate around the axis of the first inking roller 18 and the second inking roller 19, so that the distance between the first inking roller 1, the second inking roller 8 and the third inking roller 15 and the printing plate cylinder 25 changes on one side of the operating surface, thereby realizing the follow-up function of the pressure of the first inking roller 1, the second inking roller 8 and the third inking roller 15 and the printing plate cylinder 25 as the inclination of the printing plate cylinder 25 is adjusted.

[0040] When the inking mechanism with the following and self-steering functions of the present invention is used, the distance between the first inking roller 1 and the third inking roller 15 and the ink-steering roller is adjusted by the eccentric sleeve 27. When the eccentric sleeve 27 is adjusted, the adjustment scales of the eccentric sleeve 27 at both ends of the inking roller are ensured to be consistent, thereby ensuring that the pressure at both ends of the inking roller and the ink-steering roller is consistent. Since the eccentric sleeve 27 is provided with a linear bearing 28, during the printing process, the ink-steering roller drives the inking roller to perform axial movement, thereby solving the problem of "ghosting" during the printing process. When the plate cylinder 25 needs to be tilted, the plate tilting mechanism is located outside the operating surface wall panel, and the worm gear mechanism of the plate tilting mechanism drives the plate cylinder tilting eccentric sleeve 26 to rotate, thereby realizing the tilting of the plate cylinder 25. The first follower connecting rod 32 and the second follower connecting rod 33 drive the eccentric swing seat 34 and the swing rod c14 to swing with the movement of the plate tilting mechanism, thereby completing the adjustment of the first inking roller 1, the second inking roller 8 and the third inking roller 15 close to one end of the operating surface, and realizing the pressure of the inking roller and the plate cylinder 25 following the tilting of the plate cylinder 25.
