Description

Technical Field

[0001] This utility model relates to the technical field of cup body printing equipment, specifically to a cup body inclined plate printing device. Background Technology

[0002] Currently, cylindrical roller printing devices are commonly used for printing on the outer surface of paper cups. The printing roller of this device has a cylindrical structure. During printing, the cylindrical roller is directly pressed against the outer surface of the cup. The ink is transferred to the surface of the cup by the rotation of the roller, thus completing the printing operation.

[0003] However, paper cups are usually conical, with their outer diameter gradually decreasing from the rim to the bottom. When a cylindrical roller prints directly onto the outer surface of the conical cup, the contact line between the roller and the cup is not of equal diameter along the cup's axial direction. The outer diameter at the rim is larger and the linear velocity is higher, while the outer diameter at the bottom is smaller and the linear velocity is lower. This results in a difference in the relative linear velocity of each point in the contact area between the roller and the cup along the cup's axial direction. This difference in linear velocity causes the amount of ink transferred at the top of the cup to differ from that at the bottom during the same printing stroke. Areas with a larger difference in linear velocity are prone to having a darker or lighter printing density. Specifically, this manifests as inconsistencies in the printing color, ink layer thickness, and pattern clarity between the rim and bottom areas, resulting in a color difference or a blurred pattern that is visible to the naked eye.

[0004] Furthermore, the difference in linear speed can also affect the uniformity of the pressure of the roller on the cup, further aggravating the problem of uneven printing depth. In severe cases, defects such as local missing prints or ink accumulation may occur, directly affecting the appearance quality and printing consistency of the paper cup.

[0005] In summary, existing cylindrical roller printing methods cannot guarantee consistent printing quality when dealing with conical cups due to the different linear velocities at the top and bottom of the cup. Therefore, there is an urgent need for a printing device that can adapt to the surface characteristics of conical cups. Utility Model Content

In conjunction with the fan-shaped printing plate on the rotating disk, the printing plate can transfer ink in an attitude that adapts to the surface of the conical cup. This eliminates the difference in linear velocity at various points along the axial direction of the conical cup, solves the problems of inconsistent ink transfer and uneven pressure caused by the cup's taper, avoids defects such as local missing prints or ink accumulation, and ensures the consistency of printing quality on the outer surface of the conical cup.

[0009] The aforementioned cup-body inclined plate printing device can be further configured as follows: the first inclined transfer roller assembly includes a plurality of first inclined transfer rollers with the mounting frame located at the bottom of the roller unit, a first driving assembly for driving the first inclined transfer roller is provided on one side of the first inclined transfer roller, the mounting frame is provided with inclined roller fixing frames on both sides of the first inclined transfer roller, the first inclined transfer roller is rotatably connected to the inclined roller fixing frames, and the first driving assembly passes through the inclined roller fixing frames and is connected to any end of the first inclined transfer roller.

[0010] Using the above technical solution, the mounting frame is provided with several first inclined transfer rollers at the bottom of the roller unit. A first drive assembly is provided on one side of the first inclined transfer roller. Inclined roller fixing frames are provided on both sides of the mounting frame. The first inclined transfer rollers are rotatably connected to the inclined roller fixing frames. The first drive assembly passes through the inclined roller fixing frames and connects to the end of any first inclined transfer roller. The first inclined transfer rollers are stably installed on the mounting frame through the inclined roller fixing frames, and the first drive assembly directly drives the first inclined transfer rollers to rotate through the inclined roller fixing frames. This provides reliable installation support and stable power input for the inclined transfer rollers, ensuring the smooth operation of the inclined transfer rollers in an inclined posture, thereby ensuring the continuity and stability of ink in the inclined transfer path.

[0011] The aforementioned cup-body inclined plate printing device can be further configured as follows: the second inclined transfer roller assembly includes a second inclined transfer roller with a mounting frame located at the bottom of the first inclined transfer roller, the second inclined transfer roller abutting against the first inclined transfer roller, and the mounting frame located on one side of the second inclined transfer roller is provided with a second driving component for driving the second inclined transfer roller to rotate and a second locking mechanism for locking the second inclined transfer roller when the machine stops.

[0012] Using the above technical solution, a second inclined transfer roller is provided at the bottom of the first inclined transfer roller on the mounting frame. The second inclined transfer roller abuts against the first inclined transfer roller. A second drive assembly for driving the second inclined transfer roller to rotate and a first locking mechanism for locking the second inclined transfer roller when the machine stops are provided on one side of the mounting frame. The ink transfer path is formed by the abutment between the second inclined transfer roller and the first inclined transfer roller. The second drive assembly provides independent power to the second inclined transfer roller, ensuring stable ink transfer during the inclined transfer process. At the same time, the first locking mechanism locks the second inclined transfer roller when the machine stops, preventing the roller from rotating unexpectedly when the equipment is stopped, which could cause ink distribution disorder or position displacement. This ensures the accuracy of the printing position and the reliability of ink transfer when the equipment is restarted.

[0014] Using the above technical solution, the second drive assembly includes a second drive source, and the second oblique transfer roller is composed of a second roller shaft and a second conical roller. The drive end of the second drive source is fitted with a mounting frame and has a first transmission gear at the end. The second roller shaft has a second transmission gear on the side facing the first transmission gear. The two gears mesh to enable the second drive source to drive the second conical roller to rotate. The first locking mechanism can lock the second transmission gear, so that the second conical roller remains locked when the machine stops. The gear meshing transmission realizes the stable power transmission of the second drive source to the second conical roller, ensuring the continuity of the roller's operation during the oblique transfer process. At the same time, by locking the second transmission gear, the rotation of the second conical roller is restricted when the machine stops, avoiding the roller from undergoing unexpected displacement due to inertia or external force after the equipment stops, and ensuring the accuracy of the printing start position when restarting.

[0015] The aforementioned cup body inclined plate printing device can be further configured as follows: the second roller shaft passes through the mounting frame, the second locking mechanism includes a first locking gear mounted on the end of the second roller shaft facing the second driving source, the mounting frame is provided with a rotating screw at the bottom of the first locking gear, the rotating screw meshes with the first locking gear, a second locking block and a second locking handle are mounted on the end of the transmission screw, and a rotating bearing is provided between the transmission screw and the locking block.

The operator can control the locking and releasing by rotating the handle. The structure is simple and easy to operate. At the same time, the setting of the rotating bearing reduces the friction between the transmission screw and the locking block, ensuring the smoothness of the locking action, thereby reliably limiting the rotation of the second cone roller when the machine stops.

[0017] The aforementioned cup body inclined plate printing device can be further configured such that: the cup body clamp includes an L-shaped third drive source, the end of the third drive source is provided with a shaft mounting block for limiting the output end of the third drive source, the end of the output end of the third drive source is provided with a conical barrel block for the cup body to be fitted, and the conical barrel block is placed on top of the printing plate to enable the cup body to fit against the fan-shaped printing plate.

The end of the third drive source is provided with a shaft mounting block that limits the output end. The output end of the third drive source is provided with a conical block for the cup to fit on. The conical block is placed on top of the printing plate to enable the cup to fit against the fan-shaped printing plate. The L-shaped third drive source, together with the shaft mounting block, forms a stable limit on the output end, ensuring the positioning accuracy of the cup during the printing process. The conical block at the output end is for the cup to fit on and is placed on top of the printing plate, so that the conical cup can fit against the surface of the fan-shaped printing plate, providing a structural basis for the surface contact fit between the cup and the printing plate during the printing process.

A limiting block is provided on the surface of the mounting plate, and the adjustment plate has an adjustment limiting groove. The limiting block is placed within the adjustment limiting groove. The drive component pushes the adjustment plate hinged to the mounting plate, causing the rotating disk on top of the adjustment plate and the printing press to tilt together, thus achieving flexible adjustment of the printing angle. Simultaneously, the cooperation between the limiting block and the adjustment limiting groove guides and limits the movement trajectory of the adjustment plate during adjustment, ensuring the stability and repeatability of the adjustment.
