Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment and relates to an exhaust device for printing equipment. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and conveying. The working principle of a printing press is as follows: the text and image to be printed are first made into a printing plate, which is then mounted on the printing press. Ink is then applied to the areas of the plate where the text and image are located. The ink is then directly or indirectly transferred to the substrate, which can include textiles, metal plates, plastics, leather, wood, glass, and ceramics, thereby reproducing a printed product identical to the printing plate.

[0003] The printing press generates a large amount of heat and exhaust gas during operation. If they are not discharged in time, the stability and life of the machine will be affected. Although an air hood can be installed above the printing press unit to collect heat and exhaust gas, the position of the air hood is fixed. The printing roller will touch the air hood when it is replaced and lifted, which is inconvenient to operate. Utility Model Content

[0004] In response to the above-mentioned problems existing in the prior art, the present application provides an exhaust device for a printing device.

[0005] The technical solution of the utility model is as follows:

[0006] An exhaust device for printing equipment includes a slitting hood 1 and a slitting hood 2. The slitting hood 1 and the slitting hood 2 are arranged above a printing press unit. The printing press unit is equipped with a printing roller. A roller is provided at the bottom of the slitting hood 2. When the slitting hood 2 moves to the right, it is combined with the slitting hood 1. When the slitting hood 2 moves to the left, it is separated from the slitting hood 1. The roller is equipped with a transverse guide rail. The transverse guide rail is connected to a concrete floor slab through a hanging rod. A fan is installed at the bottom of the concrete floor slab. A circular pipe is provided between the fan and the slitting hood 1.

[0007] As a preferred embodiment of the present invention: an electric hoist is provided below the concrete floor slab, and the electric hoist is equipped with a hook.

[0008] As a preferred embodiment of the present invention, the hook lifts the printing roller via a lifting belt.

[0009] As a preferred embodiment of the present invention: a butterfly valve is installed on the top of the concrete floor, and a bend pipe is provided above the butterfly valve.

[0010] As a preferred embodiment of the present invention: the first slitting cover is installed with a first sealing plate, and the second slitting cover is installed with a second sealing plate.

[0011] As a preferred embodiment of the present invention: a limit switch is provided on the transverse guide rail.

[0012] The beneficial effects of the utility model are:

[0013] The utility model discloses an exhaust device for printing equipment. A roller is provided at the bottom of a slitting cover second. When the printing press is in daily operation, the slitting cover second moves to the right by the roller and combines with the slitting cover first, so that the heat and exhaust gas generated by the printing press are discharged in time. When the printing press needs to replace the printing roller, the slitting cover second moves to the left by the roller and separates from the slitting cover first, so that the printing roller does not touch the slitting cover second above when it is lifted for replacement. When the printing roller is replaced, the slitting cover second moves to the right by the roller and combines with the slitting cover first, so that the printing press unit continues to operate normally, which is convenient and reliable.
