Embodiment 1

[0066] Such as Figure 1 to Figure 4 As shown, a high-efficiency and fast drying equipment for paper tubes includes:

[0067] Drying box 1, the drying box 1 is a rectangular parallelepiped, the two ends of its length direction are respectively provided with a filling port 11 and a discharge port 12, and the filling port 11 is higher than the discharge port 12, The lower part of the side wall where the length direction and height direction of the drying box 1 are located is provided with a symmetrical recessed part 13, and the recessed part 13 is arranged along the length direction of the drying box 1;

[0068] The filling device 2, the filling device 2 is arranged at the filling port 11, which includes a number of parallel packing bins 21, the packing bins 21 are horizontally arranged along the width direction of the drying cabinet 1, and the filling bins 21 horizontally move the conveying paper cylinder 20 into the drying box 1 along the direction perpendicular to the length...

Embodiment approach

[0109] Such as Figure 10 As shown, as a preferred embodiment, the swing assembly 72 includes:

[0110] Avoidance groove 721, the avoidance groove 721 is provided on the connecting plate 7111 in one-to-one correspondence with the exhaust gas discharge cover 6;

[0111] A transmission gear 722, the transmission gear 722 is sheathed on any end of the exhaust gas discharge cover 6 in the axial direction; and

[0112] The transmission rack 723, the transmission rack 723 is fixedly connected with the corresponding connecting plate 7111, it slides along the vertical direction with the connecting plate 7111, and it is set in mesh with the transmission gear 722 to drive the exhaust gas discharge The cover 6 rotates and swings.

[0113] It should be noted that the wedge-shaped block 7162 cooperates with the ball 715 to lift the lifting rod 711, and at the same time, through the cooperation of the transmission rack 723 installed on the lifting rod 711 and the transmission gear 722, th...

Abstract

The invention provides paper tube efficient and rapid drying equipment. The paper tube efficient and rapid drying equipment comprises a drying box body, wherein a packing device and a discharging device are respectively arranged on the two ends of the drying box body in the length direction; a drying set is arranged between the packing device and the discharging device; the drying set comprises drying rollers which are arranged at equal intervals in the length direction of the drying box body; a heating air jetting opening and a free roller are arranged between every two adjacent drying rollers; and a waste gas discharging cover is arranged above each free roller. According to the paper tube efficient and rapid drying equipment, the inner circumference of a paper tube is dried through theheating air jetting openings while the outer circumference of the paper tube is dried through the drying rollers, intermittent sealing is carried out on the heating air jetting openings, intermittentairflow heating is formed, and gas circulation in the inner circumference of the paper tube is guaranteed; and waste gas is quickly discharged through the waste gas discharging cover, the relative humidity in the drying box body is avoided to be larger and larger, and the technical problem that traditional paper tube drying equipment cannot achieve high-standard paper tube drying is solved.

Description

technical field [0001] The invention relates to the technical field of paper tube drying and processing machinery, in particular to a high-efficiency and fast drying equipment for paper tubes. Background technique [0002] After the paper roll is rolled, the glue contained in the paper roll must be dried. Now the boiler is generally used to generate steam, and the steam is piped into the drying box for heating and drying. Because the steam pipe in the drying box The heat energy is transferred to the surface layer of the paper tube through the natural convection of the air in the room, and then gradually penetrates into the inner layer of the paper tube wall thickness. At the same time, the relative humidity of the air in the room will increase with the evaporation of water in the paper tube. Therefore, the drying speed of the paper tube is very slow, generally takes 2 to 3 days, and at the same time, a large amount of heat energy in the air is transferred to the ground and w...
