[0074] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0075] Embodiment one

[0076] An ink rapid drying device for newspaper printing, comprising: a main body 1, an inlet 11, an outlet 12;

[0077] The main body 1 is configured as a rectangle, and an oven cavity 13 for drying is formed inside the main body 1. The side wall of the main body 1 in the length direction forms the inlet 11. The outlet 12 is arranged on the main body 1 and is arranged opposite to the inlet 11.

[0078] The ink rapid drying device for newspaper printing further comprises: an oven plate 2, a feeding mechanism 5, and an oven mechanism 3.

[0079] The oven plate 2 is arranged in the oven cavity 13, and the upper end surface of the oven plate 2 is flush with the bottom of the inlet 11 and the outlet 12. An internal cavity 21 for mounting the oven mechanism 3 is formed. Specifically, a plurality of support tables 22 are fixedly arranged on the surface of the oven plate 2, and the plurality of support tables 22 are uniformly arranged along the length and width directions of the oven plate 2. Preferably, the projection of the support table 22 on the side wall of the main body 1 is a trapezoid, and the end away from the surface of the oven plate 2 is a small end. In this way, the contact area between the newspaper and the oven plate 2 can be reduced during the drying process, thereby preventing ink from polluting other areas of the newspaper.

[0080] More specifically, an air inlet groove 221 is formed in the support table 22, and the inner wall of the air inlet groove 221 forms a plurality of air blowing holes 222, so that the hot air generated by the oven mechanism 3 blows towards the newspaper located on the support table 22. Preferably, the air blowing holes 222 form a jet trajectory for guiding the hot air to blow towards the newspaper, and the jet trajectory forms a first jet angle with the surface of the newspaper. The first jet angles formed by the air blowing holes 222 on different side walls of the same support table 22 are different. The first jet angles formed by the air blowing holes 222 on opposite side walls of adjacent two support tables 22 are different. When blowing hot air for drying, different first jet angles give different jet ranges to the hot air. In this way, the uniformity of drying can be improved.

[0081] The oven mechanism 3 is arranged in the internal cavity 21 and is used for drying the surface of the newspaper located on the oven plate 2 and in contact with the surface of the oven plate 2. The oven mechanism 3 comprises: a heating box 31, a heating pipe 32, and a blower 33.

[0083] As an improvement, the part between the adjacent two rows of driving support tables 22 in the width direction of the drying plate 2 penetrates; and the side of the penetrating part is flush with part of the heating box 31 to form a collection channel 34; the side wall of the drying plate 2 forms a receiving groove 35 communicating with the collection channel 34; wherein the part of the inner wall of the heating cavity located in the collection channel 34 is provided with a blowing pipe, and the blowing pipe blows air towards the receiving groove 35; specifically, the blowing pipe is connected with the blower 33; in this way, the debris generated on the newspaper during drying can fall into the collection channel 34, and then the debris is blown into the receiving groove 35 through the blowing pipe 36; in this way, automatic collection of the debris is realized, and the cleanliness of the newspaper is improved; in addition, when the blowing pipe blows air, the air speed of the collection channel 34 is fast, which reduces the air pressure of the collection channel 34, so that a certain suction force is generated to adsorb the newspaper on the drying plate 2, preventing the newspaper from flying during blowing.

[0084] More specifically, the hot air pipes 4 are fixedly arranged on the two inner side walls of the drying cavity 13 above the drying plate 2, and the hot air pipes 4 are connected with the drying mechanism 3 to generate hot air in the hot air pipes 4. A plurality of nozzles 41 are arranged on the hot air pipes 4 and are uniformly distributed along the length direction of the drying plate 2. The nozzles 41 located on the two sides of the drying cavity 13 are arranged in a staggered manner on the same plane. The nozzles 41 form a jet trajectory for guiding the hot air to blow towards the newspaper, and the jet trajectory forms a second jet angle with the upper surface of the newspaper.

[0085] During blowing hot air for drying, the nozzles 41 located on the two sides of the drying cavity 13 are arranged in a staggered manner, so that the hot air blown by the nozzles 41 can be more comprehensively blown to the surface of the newspaper, improving the stability of drying. Due to the second jet angle formed by the nozzles 41, the paper debris on the newspaper can be blown into the receiving groove 35, improving the cleanliness.

[0086] As an improvement, the hot air pipe 4 is connected with the heating box 31 through a metal pipe 42, and the gas inside the heating box 31 can enter the metal pipe 42; the hot air pipe 4 located on both sides of the drying cavity 13 is provided with an electromagnetic valve 43 connected with the metal pipe 42; wherein, the two electromagnetic valves 43 are alternately opened and closed, so that the two hot air pipes 4 alternately generate hot air; in this way, the hot air is avoided from blowing on one place of the newspaper, causing the newspaper to wrinkle.

[0087] The feeding mechanism 5 is arranged on the inner wall of the drying cavity 13 and is used for feeding the newspaper to the drying plate 2; comprising: a guide rail 51, a sliding block 52, a driving part 6, a mechanical claw 53;

[0088] The guide rail 51 is provided with two, which are arranged on the side walls of the drying cavity 13 and extend along the length direction of the drying cavity 13; specifically, the guide rail 51 protrudes on the side wall in the length direction of the main body 1; and the upper end surface of the drying plate 2 is flush with the lower surface of the guide rail 51;

[0089] The surface of the guide rail 51 is partially recessed to form a limiting groove 511, and the sliding block 52 is arranged on the surface of the guide rail 51 and partially protrudes to insert into the limiting groove 511, so that the sliding block 52 can only slide along the extension direction of the guide rail 51;

[0090] Specifically, the mechanical claw 53 is arranged on the sliding block 52, which is a prior art directly purchased on the market and is used for automatically clamping the newspaper;
