Description

Device for cooling paper in printing process

Technical Field

The utility model relates to a cooling device field especially relates to a printing in-process carries out refrigerated device to the paper.

Background

The temperature of the printing paper is still high after the finished product is discharged from the oven, which is not beneficial to rolling and packaging of the finished product paper, and the paper is often cooled, so that the temperature of the paper is reduced.

At present, the cooling is directly carried out through the fan, the cooling of a general air outlet is quicker, the integral cooling is uneven, the cooling effect is not good, and the paper quality is not high. And because the temperature of the paper after baking is very high, the paper with very high temperature is piled up together and causes the expansion and contraction amplitude of the paper to be very large, which is not beneficial to the treatment of the subsequent production process.

SUMMERY OF THE UTILITY MODEL

The utility model discloses mainly solve prior art and directly cool off through the fan, whole cooling is inhomogeneous, the cooling effect is not good, the not high technical problem of paper quality, provide a printing in-process and carry out refrigerated device to the paper, come the paper cooling through recirculated cooling water to improve cooling speed, make the cooling even, promote the cooling effect.

The utility model provides a device for cooling paper in the printing process, include: the cooling device comprises a cooling roller (1), a water pump (7), a water storage tank (10) and a cooling tower (11);

the cooling roller (1) is provided with a hollow inner cavity;

the water storage tank (10) is provided with a cooling tower (11), a water outlet of the water storage tank (10) is communicated with a water inlet of the water pump (7), a water outlet of the water pump (7) is communicated with one end of an inner cavity of the cooling roller (1) through a water inlet pipeline (6), and the other end of the inner cavity of the cooling roller (1) is communicated with a water return port of the water storage tank (10) through a water return pipeline (9);

the water inlet pipeline (6) is connected with the cooling roller (1) through a rotary joint (4), and the cooling roller (1) is connected with the water return pipeline (9) through the rotary joint (4).

Preferably, both ends of the cooling roller (1) are arranged on the cooling roller bracket (2) through bearings (3).

Preferably, the water inlet pipeline (6) is provided with a water inlet valve (5).

Preferably, the water return pipeline (9) is provided with a water return valve (8).

The utility model provides a pair of carry out refrigerated device to paper among printing process compares with prior art and has following advantage:

1. the utility model discloses found cold water circulating system to water is coolant, can carry out even cooling to the paper, and the cooling effect is good.

2. And rotary joints are arranged at two ends of the cooling roller, so that the cooling roller can rotate along with the transmission of paper, and the cooling roller can rotate flexibly.

3. The installation controllability is strong, and the space is not occupied.

Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.

Fig. 1 is a schematic structural diagram of an apparatus for cooling paper in a printing process according to an embodiment of the present invention. As shown in fig. 1, the embodiment of the present invention provides an apparatus for cooling paper in printing process, including: cooling roller 1, water pump 7, reservoir 10 and cooling tower 11.

The cooling roller 1 is provided with a hollow inner cavity. The inner cavity is used for passing cooling water, and the paper is cooled when passing below the cooling roller 1.

Cistern 10 sets up cooling tower 11, and cistern 10 can set up outdoor, the delivery port of cistern 10 communicates the water inlet of water pump 7, the delivery port of water pump 7 passes through the one end of inlet channel 6 intercommunication chill roll 1 inner chamber, the other end of chill roll 1 inner chamber passes through the return water mouth of return water pipeline 9 intercommunication cistern 10.

The inlet channel 6 is connected through rotary joint 4 with chill roll 1, chill roll 1 passes through rotary joint 4 with wet return 9 and is connected, but rotary joint 4 water-flowing autogyration. The water inlet pipeline 6 is provided with a water inlet valve 5. The water return pipeline 9 is provided with a water return valve 8. And two ends of the cooling roller 1 are arranged on a cooling roller bracket 2 through bearings 3.

In this embodiment, the water inlet valve 5 is a valve for controlling the water inlet pipe 6, the water return valve 8 is a valve for controlling the water return pipe 9, the water pump 7 provides power for circulating water, and the outdoor water reservoir 10 is cooled by the cooling tower 11.

In the device for cooling paper in the printing process provided by this embodiment, the cooling roller 1 may be configured above the paper outlet of the oven, and the cooling roller 1 rotates along with the transmission of the paper; the water in the reservoir 10 is sent to the hollow inner cavity of the cooling roller 1 through the water inlet pipe 6 under the action of the water pump 7, and then returned to the reservoir 10 through the water return pipe 9, and the water in the reservoir is cooled by the cooling tower 11. The two ends of the cooling roller 1 are provided with rotary joints 4, so that the cooling roller 1 can rotate along with the transmission of paper. The temperature of the water is kept low throughout the cycle, thus keeping the temperature of the chill roll 1 at a relatively low temperature, which drops as the sheet passes through the chill roll.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: it is to be understood that modifications may be made to the technical solutions described in the foregoing embodiments, or some or all of the technical features may be equivalently replaced, without substantially departing from the scope of the technical solutions of the embodiments of the present invention.
