Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a lateral movement mechanism for printing rollers in a printing press. Background Technology

[0002] In packaging printing, label printing, and multicolor overprinting processes, the lateral position accuracy of the printing press rollers directly determines the overprinting quality and production efficiency. With the increasing market demand for printing precision and the popularization of multi-unit and multi-color overprinting processes, it is particularly important to develop a lateral movement mechanism for printing press rollers.

[0003] Referring to the lateral movement device for the printing roller of a printing press with announcement number CN216183604U, it includes: a lateral movement outer sleeve, which is coaxially mounted on a bearing seat and opposite to the printing roller; a lateral movement mechanism, which is installed inside the lateral movement outer sleeve and is used to push the printing roller to move axially; and a pushing mechanism, which is used to push the lateral movement mechanism along the axis, thereby driving the printing roller to move along the axial direction. This device has a simple structure, can adjust the printing position of the printing roller with high precision, and can lock the adjusted position. It has high reliability, is easy to maintain, and has a long service life. As can be seen from the above, although this movement mechanism can be well applied, it is usually not convenient for electrically and stably adjusting the position of the printing roller component. Therefore, the adjustment effect of this movement mechanism on the printing roller component is still difficult to achieve the expected result and needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a lateral movement mechanism for the printing roller of a printing press, in order to solve the problem that although the movement mechanism mentioned in the background art can be well applied, it is usually not convenient to electrically and stably adjust the position of the printing roller component, so that the adjustment effect of the movement mechanism on the printing roller component is still difficult to achieve the expected result.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transverse moving mechanism for a printing press roller, comprising a base plate, a lead screw rotatably mounted on the bottom end of the base plate via a bracket, limiting rails on both sides of the bottom end of the base plate, a motor mounted on one side of the bottom end of the base plate via a bracket, a rotating shaft mounted on the output end of the motor via a coupling, the end of the rotating shaft away from the motor being connected to one end of the lead screw, a nut seat threadedly mounted on the outer wall of one side of the lead screw, rail blocks on both sides of the top of the nut seat, the top of the rail blocks being slidably connected to the bottom end of the limiting rails, a bearing frame at the bottom end of the nut seat, a placement plate fixedly mounted on the lower end of the surface of the bearing frame, and a side connecting seat fixed on the outer wall of one side of the placement plate.

[0006] Preferably, T-shaped positioning seats are provided on both sides of the top of the substrate, and waist-shaped holes are provided on both sides of the top of the T-shaped positioning seats. The T-shaped positioning seats and waist-shaped holes are provided to bolt and install the entire moving mechanism.

[0007] Preferably, a fixed bearing seat is fixedly installed on one side of the interior of the mounting plate, and a movable bearing seat is slidably installed on the other side of the interior of the mounting plate. The movable bearing seat and the fixed bearing seat are arranged to support and accommodate the first bearing seat and the second bearing seat.

[0008] Preferably, the movable bearing seat has a threaded rod installed on its internal thread. One end of the threaded rod extends to the outside of the movable bearing seat and is rotatably connected to the inner wall of the side connecting seat. A handle is fixed on the outer wall of the threaded rod near the side connecting seat. By rotating the handle, the threaded rod can be driven to rotate.

[0009] Preferably, the top of the side connector is provided with a locking seat, and a locking bolt is installed on the outer wall of the locking seat. One end of the locking bolt passes through the locking seat and is threadedly connected to the outer wall of the handle. The handle is locked by passing through the locking seat and screwing into the outer wall of the handle.

[0010] Preferably, a first vertical frame is fixed to the bottom of the fixed support, and a first shaft seat is rotatably installed at the lower end of the first vertical frame. A second vertical frame is fixed to the bottom of the movable support, and a second shaft seat is rotatably installed at the lower end of the second vertical frame. An printing roller body is provided between the first vertical frame and the second vertical frame. A roller shaft is fixed at the center position inside the printing roller body. The two ends of the roller shaft extend into the interior of the first shaft seat and the second shaft seat, respectively. The two ends of the roller shaft are movably connected to the first shaft seat and the second shaft seat, respectively. The first shaft seat and the second shaft seat are provided to facilitate the disassembly and assembly of the two ends of the roller shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the transverse moving mechanism of the printing press roller not only ensures the adjustment effect of the printing roller body when the moving mechanism is used, but also achieves the purpose of easy disassembly and maintenance of the printing roller body, and can effectively prevent the rotating handle from rotating on its own.

[0012] The motor drives the lead screw to rotate via the rotating shaft, causing the nut seat to slide on the outer wall of the lead screw. The nut seat then drives the rail block to slide at the bottom of the limit rail. This allows the nut seat to drive the printing roller body to move smoothly laterally via the support frame and other related components. This enables electric and stable lateral adjustment of the printing roller body, thus ensuring the adjustment effect of the moving mechanism on the printing roller body during use.

[0013] By rotating the handle, the threaded rod is driven to rotate on the inner wall of the side connecting seat. At this time, the moving bearing seat slides on the outer wall of the threaded rod and the inner side of the mounting plate, which can adjust the distance between the fixed bearing seat and the moving bearing seat. When the fixed bearing seat and the moving bearing seat are far apart, the first bearing seat and the second bearing seat are disengaged from both ends of the roller shaft. When the fixed bearing seat and the moving bearing seat are close to each other, the first bearing seat and the second bearing seat are sleeved on both ends of the roller shaft, thereby achieving the purpose of easy disassembly and maintenance of the printing roller body.

[0014] By tightening the locking bolt, one end of the locking bolt passes through the locking seat and is screwed into the threaded hole reserved on the outer wall of the handle, thus locking the handle and effectively preventing the handle from rotating on its own. Attached Figure Description
