Description

Cooling roller mechanism on printing machine

Technical Field

The utility model relates to a part on the printing machine, concretely relates to chill roll mechanism on printing machine.

Background

A printer is a machine that prints text and images. Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate.

After the printing stock is printed, the ink on the surface of the printing stock needs to be dried, and the ink needs to be easily wiped off in the rolling process because the ink is not cooled after being dried, so that the quality of a finished product is influenced.

Disclosure of Invention

In order to solve the above problem, an object of the present invention is to provide a cooling roller mechanism on a printing machine capable of cooling rapidly, so as to cool the printing ink rapidly on the printing material after imprinting, so as to keep the printed pattern stable.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a chill roll mechanism on printing machine, includes both sides board, hollow roller, connects the first pivot of roller one end and connection are in the second pivot of the roller other end, the cylinder passes through first pivot and the rotatable installation of second pivot on the curb plate, and the second pivot is the cavity setting, is connected with the water tank on the terminal surface outside one of them curb plate, inserts an inlet tube on the water tank, and inside this inlet tube passed the cavity position entering roller of second pivot, the hollow inner wall of the pivot of roller inner chamber, inlet tube outer wall and one side formed out the water passageway, and this water passageway and water tank communicate with each other be equipped with the outlet pipe on the water tank.

The first rotating shaft is provided with a first bearing which is rotatably connected with one side plate, and the second rotating shaft is provided with a second bearing which is rotatably connected with the other side plate.

And a positioning sleeve cup is arranged on the water tank, the central axis of the positioning sleeve cup is aligned with the central axis of the second rotating shaft, the water inlet pipe penetrates through the sleeve cup, and the outer wall of the water inlet pipe is in contact with the inner wall of the positioning sleeve cup.

The utility model discloses a structure, because inside inlet tube disect insertion roller for the cooling water gets into roller and can carry out cold conduction to the roller after inside, and the cooling water is discharged from the outlet pipe after the exhalant canal process, thereby makes the cooling water effectively through the roller inner chamber, makes the laminating cool down through the stock of this roller outer wall, has effectively improved the cooling efficiency of printing ink on the stock, makes the printing pattern remain stable.

The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1, the embodiment discloses a cooling roller mechanism on a printing machine, which includes two side plates 1, a hollow roller 2, a first rotating shaft 21 connected to one end of the roller 2 and a second rotating shaft 22 connected to the other end of the roller 2, wherein the roller is rotatably mounted on the side plates 1 through the first rotating shaft 21 and the second rotating shaft 22, the second rotating shaft 22 is arranged in a hollow manner, a water tank 3 is connected to the outer end face of one of the side plates 1, a water inlet pipe 4 is inserted into the water tank 3, the water inlet pipe 4 passes through the hollow position of the second rotating shaft 22 and enters the roller 2, a water outlet passage 5 is formed by the inner cavity of the roller 2, the outer wall of the water inlet pipe 4 and the hollow inner wall of the rotating shaft on one side, the water outlet passage 5 is communicated with.

The first shaft 21 is provided with a first bearing 7 rotatably connected with one of the side plates 1, and the second shaft 22 is provided with a second bearing 8 rotatably connected with the other side plate 1. The structure can ensure that the roller 2 can rotate more smoothly and reliably.

A positioning sleeve cup 9 is arranged on the water tank 3, the central axis of the positioning sleeve cup 9 is aligned with the central axis of the second rotating shaft 22, the water inlet pipe 4 penetrates through the sleeve cup, and the outer wall of the water inlet pipe is contacted with the inner wall of the positioning sleeve cup 9 to realize sealing. The fixing of the water inlet pipe 4 can be more stable through the positioning sleeve cup 9, so that the newspaper outlet channel 5 is smooth.

Wherein, the length that inlet tube 4 got into roller 2 surpasss 1/2 of roller 2 length to improve the circulation length of water, and then improve the cooling speed.

Adopt above-mentioned technical scheme, because inside inlet tube 4 disect insertion roller 2 for the cooling water gets into roller 2 and can carry out cold conduction to roller 2 after inside, and the cooling water is discharged from outlet pipe 6 after 5 from water outlet channel, thereby makes the cooling water effectively through 2 inner chambers of roller, makes the laminating cool down through the stock of this roller 2 outer wall, has effectively improved the cooling efficiency of printing ink on the stock, makes the printing pattern remain stable.
