Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printer technology faces difficulties in accurately and easily mounting a cylindrical machine plate due to the machine plate's weight and the complexity of attaching and detaching it from the machine-plate drive shaft.
Innovation Solution
A machine-plate mounting device with a cylindrical machine-plate cylinder section on the machine-plate drive shaft, featuring a groove for circumferential positioning, a stopper for axial positioning, and a machine-plate fixation member that presses the machine plate into close contact with the mounting surface, allowing for simple and accurate attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the machine plate is mounted on the machine-plate cylinder fixed on the machine-plate drive shaft, then the machine plate can be securely mounted, but the mounting process becomes troublesome and inaccurate
Solution Approach 1:
The mounting device is divided into separate functional components: a machine-plate cylinder section for support, a groove for circumferential positioning, a stopper for axial positioning, and a fixation member for radial clamping. This segmentation allows each component to perform its specific function independently, making the overall mounting process simpler and more accurate.
Solution Approach 2:
The groove and stopper act as intermediary elements between the machine plate and the machine-plate drive shaft. The groove receives the engagement portion of the machine plate for circumferential positioning, while the stopper provides axial positioning. These intermediaries facilitate accurate and easy mounting without requiring direct fixation of the heavy cylinder to the drive shaft.
2Manufacturing precision
If the machine-plate cylinder is detached from the machine-plate drive shaft for mounting, then accurate attachment can be achieved, but the heavy cylinder becomes difficult to detach and attach
Solution Approach 1:
The mounting device separates the machine plate support function from the drive shaft connection function. The machine-plate cylinder section can be detached from the drive shaft, allowing the heavy cylinder to be easily handled for mounting operations, while still providing accurate positioning through the groove and stopper mechanisms.
Solution Approach 2:
The groove and stopper provide self-positioning functionality. When the machine plate is placed on the mounting surface, the engagement portion automatically fits into the groove for circumferential positioning, and the end portion contacts the stopper for axial positioning. This self-service mechanism eliminates the need for complex alignment procedures.
3Ease of operation
If the machine plate inner diameter is larger than the mounting surface outer diameter, then the plate can be easily attached, but the plate cannot be securely fixed
Solution Approach 1:
The machine-plate fixation member is designed to be radially movable, transitioning between a retracted state during attachment and an extended state during fixation. During attachment, the fixation member is retracted to allow easy placement of the machine plate. During fixation, it extends radially outward to apply clamping force, securing the plate securely.
Solution Approach 2:
The groove and stopper are pre-positioned on the machine-plate cylinder section to receive the engagement portion and end portion of the machine plate, respectively. This preliminary positioning arrangement allows the machine plate to be easily attached without requiring complex alignment, while still ensuring secure fixation through the pre-positioned groove and stopper.

AI summary
The present invention provides a machine-plate mounting device for a printer which can attach a cylindrical machine plate to the printer more easily and accurately. A machine-plate mounting device 3 is fixedly provided on a machine-plate drive shaft 1 of the printer for mounting a machine plate 2 having a form area 5 provided on a portion of an outer circumferential surface of a machine plate body 4 formed from an elastic material into a cylindrical shape and an engagement portion 6 projecting radially inward from an inner circumference of the machine plate body 5 and extending in an axial direction. The machine-plate mounting device 3 includes a machine-plate cylinder section 12 fixedly provided on the machine-plate drive shaft 1 and having, on its outer circumference, a cylindrical machine-plate mounting surface 14 on which the machine plate 2 is mounted from a front-end side of the machine-plate drive shaft 1. The machine-plate mounting device 3 is configured such that the machine-plate cylinder section 12 has, on its outer circumference, a groove 21 for circumferential positioning into which the engagement portion 6 of the machine plate 2 is fitted from the front-end side of the machine-plate drive shaft 1, a stopper 20 for axial positioning with which an end portion of the machine plate 2 comes into contact, and a machine-plate fixation member 24 which presses a portion, other than the form area 5, of the machine plate 2 mounted on the machine-plate cylinder section 12 from a radial inside direction toward a radial outside direction so as to bring the machine plate 2 into fixed-close contact with the machine-plate mounting surface 14 of the machine-plate cylinder section 12.
