Description

Technical Field

[0001] The utility model relates to the technical field of color printing machines, in particular to a feeding device for a color printing machine. Background Art

[0002] A color printer, also known as a color press, is a printing device specifically used for color printing. It can use multiple colors of ink or colorant in the printing process to produce color images, photos or texts. Color printers are widely used in commercial printing, publishing, packaging printing and other fields to produce high-quality printed products such as brochures, magazines, packaging boxes, etc.

[0003] After searching, the existing Chinese patent (publication number: CN219341065U) discloses a feeding device for a color printing machine, which relates to the field of printing feeding technology, specifically including a box body, two movable plates are arranged on one side of the box body, the movable plate is slidably connected to the box body, a main shaft is arranged between the movable plate and the box body, one end of the main shaft is rotatably connected to the inner wall of the box body, and the other end is rotatably connected to the two movable plates, and a support plate is slidably installed on the main shaft, and the two ends of the support plate are slidably connected to the box body. When the paper roll needs to be replaced, the two movable plates are pushed away from each other to release the restriction on one end of the main shaft. At this time, the support plate is pushed toward the movable plate to move, so that the paper roll of the paper is pushed out conveniently. At this time, the support plate keeps supporting the main shaft. When replacing a new paper roll, the support plate is pushed to reset by the paper roll, and then the two movable plates are pushed close to each other to fix one end of the main shaft, so that the paper roll can be replaced without disassembling the main shaft, making the entire replacement more convenient and improving the overall work efficiency.

[0004] The above-mentioned color printing machine feeding device adopts a technical solution to solve the cumbersome process of replacing the paper roll by pushing the support plate toward the movable plate. The support plate maintains support for the main shaft. When replacing a new paper roll, the support plate is pushed to reset by the paper tube. However, when replacing paper rolls of different lengths, the paper roll cannot be fixed in the middle position, and the paper roll leans to one side of the movable plate. The offset of the paper roll position will cause inaccurate alignment of the image or text, thereby affecting the printing quality. Therefore, we propose a color printing machine feeding device to solve the above problem. Utility Model Content

A slide groove is opened on the side of the circular block away from the motor. The design of the slide groove enables the sliding rod to move along a specific path when the circular block rotates, thereby achieving precise control and positioning. The movement of the sliding rod in the slide groove can accurately control the position and speed of the sliding block. The limit groove is used to limit the movement range of the sliding block to ensure that it moves within a predetermined path. The smooth movement of the moving block in the limit groove helps to maintain the stability of the entire device. The fixed connection between the limit ring and the connecting block ensures the stable cooperation between the sliding block, the limit ring and the connecting block.

The groove is designed to guide cleaning roller 2, and cleaning roller 2 can slide in the groove so that cleaning roller 2 can adapt to papers of different widths or be adjusted during the cleaning process. The connecting column is used to support cleaning roller 2 and enable cleaning roller 2 to rotate when the cleaning requirements are met. The top of the connecting column is fixedly connected to a pressure component, which is used to apply appropriate pressure to cleaning roller 2 to ensure effective contact with the paper or printing surface during the cleaning process and improve the cleaning effect.

[0012] Preferably, the pressure assembly includes a support column, the bottom end of the support column is fixedly connected to the connecting column, the end of the support column away from the connecting column is fixedly connected to the inner wall of the work frame, the outer sleeve of the support column is provided with a spring, one end of the spring is fixedly connected to the top end of the inner wall of the work frame, and the other end of the spring is fixedly connected to the connecting column.

The function of the spring is to provide the necessary elasticity and pressure to ensure the effective contact between the cleaning roller 2 and the printing material. This layout of the spring allows it to automatically adjust the pressure according to the thickness of the printing material or the operating state of the machine, thereby maintaining the consistency of the cleaning effect.

[0014] Preferably, the outer sleeve of the main shaft is provided with a roll of paper, one end of the sliding rod away from the circular block is fixedly connected to the sliding block, and one end of the circular block away from the sliding block is rotatably connected to the inner wall of the fixing frame.

The movement of the sliding block is transmitted to the roller through the limit ring and the connecting block, causing the roller to rotate. The rotation of the threaded rod causes the moving column to move along the main shaft, driving the roll paper to be pushed out or retracted, making the roll paper replacement process simpler and more efficient, reducing the complexity of operation and time consumption, and improving the adaptability to roll paper of different lengths, avoiding the offset of the roll paper during the printing process, thereby ensuring the accurate alignment of the image and text and improving the printing quality.
