[0001] The utility model relates to the field of printing, in particular to a UV glazing device for a full-automatic offset printing machine. Background Art

[0002] The offset printing press is a type of rotary printing press. It follows the principle of indirect printing, and the printing plate transfers the image and text onto the substrate through the rubber cloth transfer roller for printing. According to the printing conditions and basic printing methods, it can be divided into single-sheet automatic flat offset printing press and web-fed high-speed rotary offset printing press; according to the number of printing colors, it can be divided into single-color machine, two-color machine, four-color machine, six-color machine and eight-color machine, etc.; according to the printing paper, it can be divided into four-page machine, double-page machine, full-sheet machine and double full-sheet machine, etc. In order to meet the needs, the offset printing press also needs a UV glazing device to decorate the surface of the paper.

[0003] However, the UV glazing process requires the paper to be cured by ultraviolet light and dried at high temperature. After the drying process, the temperature of the paper is relatively high. If the dried paper is directly stacked, the temperature in the paper pile will be too high and the paper may deform and become brittle. Therefore, the dried paper needs to be placed for a period of time before storage. Utility Model Content

[0004] The utility model aims to provide a full-automatic UV glazing device for an offset printing machine, which solves the problem that dried paper needs to be placed for a period of time before being stored.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A fully automatic offset printing machine UV glazing device comprises a main body, a plurality of groups of cooling rollers are arranged behind the discharge port of the main body, each group of cooling rollers clamps paper, the cooling rollers are connected with a rotating mechanism, the rotating mechanism drives the cooling rollers to rotate and drives the paper to move, the cooling rollers are hollow inside, and rotating tubes are arranged at both ends of the cooling rollers, the rotating tubes are rotatably mounted on a mounting plate, and the rotating tubes pass through the mounting plate, the rotating tubes at both ends of the cooling rollers are connected with water pipes, and the water pipe at one end of the cooling roller is connected to a water inlet pipe, and the water pipe at the other end is connected to a water outlet pipe, the water inlet pipe and the water outlet pipe are connected to a water tank, and a water pump is installed on the water inlet pipe.

[0007] By adopting the above technical scheme, the water pump is started to pump up the water in the water tank, and the water is sent to different cooling rollers through the water pipes. The cooling rollers come into contact with the high-temperature paper, and the heat is transferred to the cold water inside through the cooling rollers. Then the water that absorbs the heat enters the water outlet pipe through the other end of the cooling roller. The water outlet pipe re-introduces the water into the water tank, and the heat is dissipated through the water tank, which effectively improves the cooling efficiency of the paper. At the same time, multiple groups of cooling rollers work at the same time, and the cooling effect is better. The rotating mechanism drives the cooling roller to rotate and drives the paper to move, so that the surface of the cooling roller can evenly contact the high-temperature paper, so that the heat dissipation effect is better, and the paper can be cooled quickly without having to be placed for a period of time before storage, which effectively improves production efficiency and reduces safety hazards.

[0008] Preferably, a rotating sealing ring is provided between the rotating pipe and the water conduit to prevent water leakage.

[0009] By adopting the above technical solution, when the rotating mechanism drives the cooling roller to rotate, the water guide pipe is fixed, the rotating tube rotates together with the cooling roller, and the rotating sealing ring effectively prevents water from flowing out of the gap between the rotating tube and the water guide pipe during the relative rotation process.

[0010] Preferably, the rotating mechanism includes a rotating drive motor, a rotating gear and a connecting gear. The rotating gear is fixedly connected to the rotating tube on one side of the cooling roller, and the rotating gears in the same group above and below are meshed with each other.

The rotating gear is connected to the rotating gear on the side through the connecting gear, so that the cooling rollers in the same row rotate in the same direction, and drive the paper forward together.

[0012] Preferably, the water outlet pipe is connected to the top of the water tank, and the top of the water outlet pipe is connected to a plurality of spray pipes, and the bottom of the spray pipe is provided with a plurality of spray ports.

[0013] With the above technical solution, the water outlet pipe is connected to the high point of the water tank, and water is sprayed evenly through the spray port below the spray pipe, so that the water can fully contact with the air and dissipate heat quickly.

[0014] Preferably, the water tank is provided with a baffle below the spray pipe, and the baffle is provided with a plurality of through holes.

[0015] By adopting the above technical solution, the water sprayed by the spray pipe falls on the baffle and then falls from the through hole, which effectively increases the time required for the water to fall to the bottom of the water tank, so that the water has sufficient time to contact with the air to dissipate heat, and transfer the heat absorbed from the high-temperature paper to the air.

[0016] Preferably, a heat conducting rod is provided inside the cooling roller.

[0017] By adopting the above technical solution, the contact area between the cooling roller and the water inside it is increased by the heat-conducting rod, so that the heat absorbed by the high-temperature paper by the cooling roller can be quickly transferred away by the contact between the heat-conducting rod and the water.

[0018] Preferably, the upper end of the water tank is open, and a support frame is fixedly connected to the opening, and a fan is installed on the support frame.

[0019] By adopting the above technical solution, the support frame fixes the fan, and starting the fan can drive the air flow in the water tank, which can effectively increase the heat dissipation efficiency of the water.

[0020] The beneficial effects of the utility model are as follows: 1. Start the water pump to pump up the water in the water tank, and send the water into different cooling rollers through the water pipes. The cooling rollers come into contact with the high-temperature paper, and the heat is transferred to the cold water inside through the cooling rollers. Then the water that absorbs the heat enters the water outlet pipe through the other end of the cooling roller. The water outlet pipe re-introduces the water into the water tank, and the heat is dissipated through the water tank, which effectively improves the cooling efficiency of the paper. At the same time, multiple groups of cooling rollers work at the same time, and the cooling effect is better. The rotating mechanism drives the cooling roller to rotate and drives the paper to move, so that the surface of the cooling roller can evenly contact the high-temperature paper, so that the heat dissipation effect is better, and the paper can be cooled quickly without being placed for a period of time before storage, which effectively improves production efficiency and reduces safety hazards.

[0021] 2. The rotary drive motor drives the driving gear to rotate, and the driving gear drives the rotating gear on the rotating tube to rotate. The rotating gear drives the rotating gear meshing with it below to rotate, so that the cooling rollers in the same group above and below rotate in opposite directions, and can drive the paper to move together. The rotating gear is connected to the rotating gear on the side through the connecting gear, so that the cooling rollers in the same row rotate in the same direction, and drive the paper forward together.

[0022] 3. The water sprayed from the spray pipe falls on the baffle and then falls from the through hole, effectively increasing the time required for the water to fall to the bottom of the water tank, so that the water has sufficient time to contact with the air for heat dissipation, and transfer the heat absorbed from the high-temperature paper to the air.
