Description

Technical Field

[0001] The utility model belongs to the technical field of plate exposure machines, and in particular relates to a plate exposure machine used for ink printing. Background Art

[0002] A plate exposure machine is a contact exposure imaging device used to make printing plates. It uses pressure (including atmospheric pressure and mechanical pressure) to make the original plate and the photosensitive plate fit closely, so that the image on the original plate can be accurately exposed on the photosensitive plate through photochemical reaction. The plate exposure machine is mainly composed of a light source device, an exposure chamber, a vacuum chamber, an electrical part, a machine base, etc. When the plate exposure machine is working, the cover plate needs to be sealed to prevent light leakage from affecting ink printing.

[0003] For example, in the Chinese utility model with announcement number CN214704299U and name of a plate exposure machine for ink printing, it specifically includes a plate exposure machine, a moving wheel, a supporting device, a rotating handle, a closing cover, a connecting roller, a bearing, a sealing cover, and a sealing device. The moving wheel is fixed at the lower end of the plate exposure machine in an equal matrix shape, and a space is opened inside the lower end of the plate exposure machine. The bearing is fixed to one side of the inner wall of the plate exposure machine, one end of the connecting roller is fixed to the inner wall of the bearing, and one end of the connecting roller passes through one side of the plate exposure machine. A groove is opened on the outer wall of the plate exposure machine, and one end of the connecting roller is located in the groove of the outer wall of the plate exposure machine. Although the plate exposure machine and the sealing cover are fitted together by hinges through the above-mentioned prior art and then sealed by a sealing device, the sealing cover and the plate exposure machine are clamped by buckles, and the clamping part is worn after a period of use, making the seal unreliable. Utility Model Content

[0004] The purpose of the utility model is to provide a plate exposure machine for ink printing with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] As a further optimization solution of the utility model, the sealing assembly includes a guide rail arranged on the lower edge of the cover plate, and a second sealing strip is fixedly arranged on the inner side of the guide rail and is tightly attached to the first sealing strip after the cover plate is closed.

[0008] As a further optimization scheme of the utility model, the locking mechanism includes a rotating sleeve arranged on the edge of the cover plate, a clamping spring is fixedly connected to the inner side of the rotating sleeve, a pull hook is fixedly connected to one end of the clamping spring, and a positioning pin cooperating with the pull hook is fixedly connected to one side of the plate exposure machine.

[0009] As a further optimization scheme of the utility model, a sliding groove is opened on the inner side of the rotating sleeve, and a slide plate slidably matched with the sliding groove is slidably arranged on the inner side of the rotating sleeve, one side of the slide plate is connected to the clamping spring, and the other side of the slide plate is connected to the pull hook.

[0010] As a further optimization solution of the utility model, a positioning shaft rotatably connected to one end of the rotating sleeve is fixedly provided on the edge of the cover plate.

[0011] As a further optimization solution of the present invention, both the first sealing strip and the second sealing strip are made of rubber material.

[0012] The beneficial effect of the utility model is that in the utility model, by closing the cover plate on the upper side of the platemaking machine and then tightening the draw hook to drive the clamping spring to extend, so that the draw hook is clamped on the positioning pin, on the one hand, the cover plate can be pressed to press the second sealing strip and the first sealing strip to fit tightly after closing, so that the clamping spring on the lower side of the first sealing strip is compressed to improve the sealing effect. On the other hand, the cover plate can be allowed to move in a small range after closing through the expansion and contraction of the clamping spring to prevent the sealing effect from being affected after long-term closing.
