Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a pressure regulating mechanism for an embossing roller. Background Art

[0002] A printing press is a device that uses a printing plate to transfer ink or other colorants to a substrate, and is an important part of the printing process. A printing press is usually composed of a transmission unit, a printing unit, an inking unit, a wetting unit, a paper feeding unit, a positioning unit, a paper transfer unit, and a paper collection unit. Different types of printing presses may have different structures and functions, but their basic principles are similar.

[0003] The existing printing unit includes a wall panel, a plate roller arranged on the wall panel, an embossing roller located on one side of the plate roller, and an adjusting mechanism for driving the embossing roller to move toward one side of the plate roller. The adjusting mechanism includes an adjusting swing arm hinged to the wall panel and a driving cylinder for driving the adjusting swing arm to rotate, the driving cylinder body is hinged to the wall panel, the piston rod is hinged to the swing arm, and the embossing roller is rotatably arranged on the adjusting swing arm. When the driving cylinder fails during use, the embossing roller linked thereto will be affected by the driving cylinder and will swing with a large stroke, thereby causing the embossing roller to collide with other components; and the adjustment method of the driving cylinder cannot well position and maintain the adjustment position accuracy of the embossing roller. Based on the above problems, the present invention is conceived. Utility Model Content

[0004] The utility model aims to provide an embossing roller pressure regulating mechanism, which has a higher safety factor in use and more precise adjustment and positioning.

[0006] By adopting the above technical solution, the swinging active area of ​​the adjusting swing arm is limited by the movable limiting area formed by the setting limiting assembly, so that when the driving part fails, the adjusting swing arm will be limited by the limiting assembly in the movable limiting area, so as to avoid the embossing roller from being involved in the driving part failure and colliding with other parts, so as to improve the safety factor of the equipment. And cooperate with the setting locking assembly to realize the precise adjustment of the adjusting swing arm, and when it is adjusted to the required position, the adjusting swing arm is stably locked by the locking assembly, so that the adjustment positioning of the structure is more precise.

[0007] It is further configured as follows: the limit assembly includes an upper limit block and a lower limit block fixed to the wall panel and located at both ends of the adjusting swing arm along its swing direction; the adjusting swing arm is located between the upper limit block and the lower limit block and the swing path overlaps with the upper limit block and the lower limit block.

[0008] By adopting the above technical solution, the upper limit block and the lower limit block are set on both sides of the adjusting swing arm to limit the swing space of the adjusting swing arm, avoiding a large swing deviation, thereby achieving the purpose of limited rotation.

[0009] It is further configured as follows: the locking assembly includes a lower adjusting locking bolt threadedly connected to the lower limit block and an upper adjusting locking stud threadedly connected to the upper limit block, and the lower adjusting locking bolt and the upper adjusting locking stud both reciprocate and spirally move toward one side of the adjusting swing arm and overlap with the swinging path formed by the adjusting swing arm.

[0010] By adopting the above technical solution, the upper adjusting locking stud cooperates with the lower adjusting locking bolt to realize stepless adjustment for accurately adjusting the position of the adjusting swing arm. When the adjusting swing arm is adjusted to the desired position, the position of the adjusting swing arm is locked by the opposite forces applied by the upper adjusting locking stud and the lower adjusting locking bolt, so that it can be stably maintained in this position, thereby ensuring the processing accuracy of the embossing roller.

[0011] It is further configured that: a tightening spring is sleeved on the upper adjusting locking stud.

[0012] By adopting the above technical solution, the tightening spring applies a locking force along the tightening direction to the upper adjustment locking stud pressed against the adjustment swing arm, thereby achieving the purpose of preventing loosening.

[0013] It is further configured that: the position where the embossing roller is connected to the adjusting swing arm is located between the hinge position between the adjusting swing arm and the wall panel and the position where the driving member is connected to the adjusting swing arm, and the position where the embossing roller is connected to the adjusting swing arm is close to the hinge position between the adjusting swing arm and the wall panel.

[0014] By adopting the above technical solution, the structure is used to increase the length of the force arm of the driving member driving the embossing roller by adjusting the swing arm, so that the driving member can achieve the driving effect with a smaller force, thereby reducing the force on the driving member and extending the service life of the driving member.

[0015] It is further configured as follows: an upwardly extending adjusting rod is connected to the upper adjusting locking stud, and a hand wheel is provided on the adjusting rod.

[0016] By adopting the above technical solution, this structure enables the staff to complete the adjustment operation of the upper adjustment locking stud while standing, and the adjustment is more labor-saving and simple.

[0017] It is further configured as follows: the driving member comprises a cylinder, a cylinder body of the cylinder is hinged to the wall panel, and a piston rod is hinged to the adjusting swing arm.

[0018] It is further configured as follows: a plurality of material-saving holes are provided on the adjusting swing arm.

[0019] By adopting the above technical solution, the material cost can be reduced on the basis of ensuring the strength of the swing arm is adjusted.

[0020] In summary, the utility model has the following beneficial effects: the utility model has a higher safety factor in use and more precise adjustment and positioning. BRIEF DESCRIPTION OF THE DRAWINGS
