FIXING UNIT AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240201623 titled 'FIXING UNIT AND IMAGE FORMING APPARATUS
The fixing unit described in the patent application includes various components such as a film, a nip forming member, a heating unit, a rotary member, and an end portion regulating member.
- The fixing unit is designed to sandwich the film between the nip forming member and the rotary member while regulating the end portion of the film in the longitudinal direction.
- The end portion regulating member has three surfaces - one facing the inner surface of the film, one facing the end face of the film, and one facing the outer surface of the film to prevent deformation.
- The third surface of the end portion regulating member is entirely located on the upstream side of the center position of the nip portion in the conveyance direction of the recording material.
Potential Applications: - This technology can be used in printing and imaging devices to ensure proper fixing of images onto various materials. - It can also be applied in packaging machinery to seal and fix packaging materials effectively.
Problems Solved: - Prevents deformation of the end portion of the film during the fixing process. - Ensures consistent and uniform fixing of materials without separation or damage.
Benefits: - Improved quality of fixed images and materials. - Enhanced durability and longevity of fixed materials. - Increased efficiency in fixing processes.
Commercial Applications: Title: Innovative Fixing Unit for Printing and Packaging Machinery This technology can be utilized in commercial printing presses, packaging companies, and imaging centers to enhance the quality and durability of fixed materials. It can lead to cost savings by reducing rework and improving overall productivity.
Questions about Fixing Unit: 1. How does the end portion regulating member prevent deformation of the film? The end portion regulating member's third surface is designed to regulate the end portion of the film from deforming in a manner separating from the first surface, ensuring proper fixing.
2. What is the significance of the positioning of the third surface of the end portion regulating member? The entirety of the third surface being disposed on the upstream side of the center position of the nip portion helps in regulating the end portion of the film effectively during the fixing process.
Original Abstract Submitted
a fixing unit includes a film, a nip forming member, a heating unit, a rotary member arranged to sandwich the film together with the nip forming member, and an end portion regulating member configured to be in sliding contact with the film and to regulate an end portion of the film in the longitudinal direction. the end portion regulating member includes a first surface facing an inner surface of the film, a second surface facing an end face of the film in the longitudinal direction, and a third surface facing an outer surface of the film and configured to regulate the end portion of the film from deforming in a manner separating from the first surface. an entirety of the third surface is disposed on an upstream side of a center position of the nip portion in a conveyance direction of the recording material in the nip portion.
