Description

Technical Field

[0001] The invention relates to the technical field of plate processing machines, in particular to a plate material protection device at a plate inlet of a plate processing machine. Background Art

[0002] A plate processor is also called a developer, which mainly refers to the process of using a reducing agent to reveal the latent image formed on a film or printing plate after exposure. The operation process of an existing plate processor generally includes a developing operation area, a washing operation area, a gluing operation area, and a drying operation area in sequence, wherein each operation area has a matching mechanism to meet the operation needs. After searching, a Chinese patent publication number CN112346306A discloses a plate material protection device for a plate inlet of a plate processor, which includes a plate processor body and a plate inlet platform, wherein the plate processor body is provided with a plate inlet, and the front end of the plate inlet is provided with the plate inlet platform connected to the outer side wall below the plate inlet of the plate processor body. This technical solution provides a plate feed table and a guide frame between the plate feed port. Although it solves the problem of easy scratches on the plate at the plate feed port and the plate feed being too high and stuck at the joint of the plate feed port, thus improving production efficiency and product quality, in actual use, the plate will cause friction and scratches on the protective film on the surface of the plate feed table during movement, thereby affecting the subsequent plate transportation, and when one end of the plate contacts the guide frame, it is easy to have rigid contact and cause jamming, thereby causing the plate to bend, which in turn affects the feeding of the plate.

[0003] The Chinese patent publication number CN218273086U discloses a plate feed protection structure for a plate punching machine. The utility model includes a body, the lower surface of the body is fixedly connected to a support leg, the upper surface of the body is installed with a glass panel, one side of the upper surface of the body is fixedly connected to a control box, and the surface of the body is installed with a feed plate. Although this technical solution can support and transport plates of different lengths and avoid personal injury through the protective structure, when in use, the protective structure has only one set of rubber pads, so the position of the plate between the rubber pads and the feed plate is in a suspended state, and the plate structure is often soft, so it is easy to bend and fall, thereby increasing the cost of use, and when the plate is transported, the position of the plate cannot be corrected, and the plate is prone to offset during feeding, which affects the effect of subsequent processing.
