Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically to a printing shaft device which is easy to disassemble. Background Art

[0002] In the printing industry, "print roller" or "print shaft" actually refers to the cylindrical rotating parts that play a key role in the printing process. These parts are usually made of metal (such as steel, stainless steel, aluminum alloy, etc.) or special engineering plastics, and their function is to transport printing materials into the printing equipment.

[0003] However, the printing roller device in the prior art is coated with a rubber layer when in use. After long-term use, its surface is prone to excessive hardening or damage, so it needs to be replaced or maintained. However, when the printing roller is currently fixed, its two ends are mostly set on both sides of the frame. When disassembling, the frame needs to be disassembled, which is quite inconvenient. In view of this, we propose a printing shaft device that is easy to disassemble. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a printing shaft device that is easy to disassemble, so as to solve the technical problem that the current printing roller device needs to be replaced or maintained when in use. However, when the printing roller is currently fixed, its two ends are mostly set on both sides of the frame, and the frame needs to be disassembled when disassembling, which is inconvenient.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a printing shaft device that is easy to disassemble, comprising a printing device for printing materials and a conveying mechanism provided on one side of the printing device for conveying materials;

[0006] The conveying mechanism comprises two symmetrically arranged L-shaped side plates, the bottom ends of the two L-shaped side plates are symmetrically constructed with two bottom plates, and the tops of the two L-shaped side plates are equidistantly provided with a plurality of U-shaped grooves, a locking mechanism is detachably installed in the plurality of U-shaped grooves, and a rubber roller is rotatably installed between the two locking mechanisms on the same side;

[0007] The locking mechanism includes a bearing seat with a mounting groove, one end of the rubber roller is rotatably installed in the mounting groove, fixing ears are constructed on both sides of the bearing seat, and two fixing grooves connected to the U-shaped groove are symmetrically provided on the top of the L-shaped side plate, the fixing ears are detachably installed in the fixing grooves, and a locking bolt threadedly connected to the L-shaped side plate is movably arranged in the fixing ears.

[0008] The utility model completes the installation of the rubber roller by two locking mechanisms located on both sides. When the rubber roller needs to be disassembled, the two locking bolts can be loosened to take out the bearing seat with two fixing ears from the U-shaped groove, so that the rubber roller and the two bearing seats can be taken out together, thereby completing the disassembly of the rubber roller. The frame does not need to be disassembled during disassembly, and the disassembly is convenient.

[0009] Preferably, a support frame is constructed at the bottom end of the bottom plate away from the printing device among the two bottom plates, and guide grooves are centrally formed on both sides of the top end of the bottom plate.

[0010] Preferably, two guide keys are symmetrically constructed at the bottom end of the L-shaped side plate, and the guide keys are slidably arranged in the guide groove.

When the rubber roller needs to be disassembled, the two locking bolts can be loosened to remove the bearing seat with two fixing ears from the U-shaped groove, so that the rubber roller and the two bearing seats can be taken out together, thereby completing the disassembly of the rubber roller. The frame does not need to be disassembled during disassembly, and the disassembly is convenient.

[0016] 2. The utility model also releases the locking of the L-shaped side plate on the two bottom plates by loosening the four fastening bolts, and pulls the L-shaped side plate to drive the guide key to slide out of the guide groove, thereby achieving fixed contact with all rubber rollers for easy replacement or maintenance.
