Abstract
Description
Technical Field
[0001] The utility model relates to the field of color box production, and relates to a color box ghost removal device. Background Art
[0002] The problem of color box ghosting usually occurs in the printing process, which is caused by the uneven distribution of ink during printing or mechanical problems of the printing machine. Ghosting can be divided into two categories: process ghosting and mechanical ghosting. Mechanical ghosting is the most common type of ghosting, mainly caused by mechanical reasons of the printing machine. Mechanical ghosting is affected by factors such as ink rollers, blankets, and printing plates on the printing machine. If the position of the ink roller is fixed and the ink on the surface of the ink roller is uneven during operation, it will cause ghosting and reduce the quality of printed products.
[0003] In summary, in order to solve the deficiencies in the prior art, it is necessary to design a color box ghost removal device with a simple structure. Summary of the Utility Model
[0004] The utility model provides a color box ghost removal device to solve the problems of the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: a color box ghost removal device includes: a frame, an ink roller, a first motor, a left coating roller, a right coating roller, a gear-rack assembly, and a housing. The ink roller is rotatably arranged on the frame and is driven by the first motor at one end. The left coating roller and the right coating roller are both in contact and arranged below the middle of the outside of the ink roller. The gear-rack assembly includes a second motor, a gear, a left rack, and a right rack. The second motor is fixed inside the housing. The gear is connected to the output end of the second motor and meshes with the left rack and the right rack. The lower ends of the left rack and the right rack are both slidably arranged inside the housing. The right coating roller is rotatably arranged at the lower end of the right connection part of the right rack. The right rack passes through the channel in the middle of the left connection part of the left rack. The left coating roller is rotatably arranged at the lower end of the left connection part. A slideway for the right connection part and the left connection part to pass through is provided on the front side of the housing.
[0006] Further improvement: a chute is provided on the housing. Guide bars are fixed to the bottoms of the left rack and the right rack, and the guide bars are slidably arranged in the chute.
[0007] Further improvement: guide sleeves are fixed to the ends of the right connection part and the left connection part. A ball bushing is clamped inside the guide sleeve, and the guide sleeve is clamped to the outer ring of the ball bushing. Plug rods are fixed to the ends of the left coating roller and the right coating roller, and the plug rods are inserted into the inner ring of the ball bushing.
[0008] Further improvement: a rotating shaft is sleeved and fixed inside the ink roller. The two sides of the rotating shaft are rotatably arranged on the frame through bearing seats, and the output shaft of the first motor is fixedly connected to one side of the rotating shaft.
[0009] Compared with the prior art, the beneficial effects of the utility model's color box ghost removal device are as follows:
[0010] The ink roller rotates through the first motor to print the ink on the ink roller onto the color box. The second motor drives the gear to rotate, thereby driving the left rack and the right rack to expand and retract synchronously outward, and then driving the left coating roller connected to the lower end of the left rack and the right coating roller connected to the right rack end to move outward or inward synchronously, evenly spreading the ink on the ink roller axially, ensuring relative uniformity at each position in the axial direction; at the same time, the right coating roller is rotatably arranged at the lower end of the right end connection part of the right rack, and the left coating roller is rotatably arranged at the lower end of the left end connection part. The ink roller will drive the left coating roller and the right coating roller in contact with it to rotate, thereby spreading the ink circumferentially, ensuring uniform ink at each position of the ink roller and reducing the ghosting phenomenon.

[0021] As Figures 1 to 4 shown, the working principle of the present utility model: retaining the structure of the original ink roller 2, the ink roller 2 rotates through the first motor 3 to print the ink on the ink roller 2 onto the color box. The second motor 51 drives the gear 52 to rotate, thereby driving the left rack 53 and the right rack 54 to expand and retract synchronously outward, and further driving the left coating roller 41 connected to the lower end of the left rack 53 and the right coating roller 42 connected to the end of the right rack 54 to move outward or inward synchronously, evenly spreading the ink on the ink roller 2 axially to ensure relative uniformity at each position in the axial direction; at the same time, the right coating roller 42 is rotatably arranged at the lower end of the right connecting portion 541 of the right rack 54 and the left coating roller 41 is rotatably arranged at the lower end of the left connecting portion 531. The ink roller 2 will drive the left coating roller 41 and the right coating roller 42 in contact with it to rotate, thereby spreading the ink circumferentially to ensure uniform ink at each position of the ink roller and reducing the ghost image phenomenon.
[0022] As a further preferred embodiment, a sliding groove 61 is provided on the casing 6. Guide bars 55 are fixed to the bottoms of the left rack 53 and the right rack 54. The guide bars 55 are slidably disposed in the sliding groove 61. The guide bars 55 of the left rack 53 and the right rack 54 slide in the sliding groove 61 to realize the support of the bottoms of the left rack 53 and the right rack 54, and at the same time ensure the stability of movement.
[0023] As a further preferred embodiment, guide sleeves 71 are fixed to the ends of the right end connecting portion 541 and the left end connecting portion 531. A ball bushing 72 is clamped inside the guide sleeve 71. The guide sleeve 71 is clamped to the outer ring of the ball bushing 72. Plug rods 73 are fixed to the ends of the left coating roller 41 and the right coating roller 42. The plug rods 73 are inserted into the inner ring of the ball bushing 72. The plug rod 73 of the coating roller 41 is connected to the connecting portion through the ball bushing 72 to realize rotational connection.
[0024] As a further preferred embodiment, a rotating shaft 21 is sleeved and fixed inside the ink roller 2. Both sides of the rotating shaft 21 are rotatably disposed on the frame 1 through bearing seats. The output shaft of the first motor 3 is fixedly connected to one side of the rotating shaft 21. Power is transmitted from the first motor 3 to the output shaft and the rotating shaft, and then drives the ink roller 2 fixed outside the rotating shaft 21 to rotate.
