[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a drying mechanism for corrugated cardboard box processing, including a housing 1, a roller conveyor 2 inside the housing 1, inlets and outlets at the left and right ends of the housing 1, an upper drying mechanism 3 fixedly installed on the top inner wall of the housing 1, and a waste gas treatment mechanism 4 on the housing 1. A limiting cylinder 6 is fixedly sleeved on the conveying roller 201 of the roller conveyor 2. The roller conveyor 2 conveys the cardboard, the limiting cylinder 6 limits the cardboard, the upper drying mechanism 3 dries the cardboard, and the waste gas treatment mechanism 4 treats the waste gas generated during drying.

[0022] Multiple limiting cylinders 6 are installed at equal intervals on different conveying rollers 201 of the roller conveyor 2. The end of the limiting cylinder 6 is provided with a guide groove 601. The inner wall of the limiting cylinder 6 is rotatably connected to a bidirectional lead screw 604 through a bearing. The outer wall of the bidirectional lead screw 604 is threaded with a moving ring 602. The edge of the moving ring 602 is provided with an integrally formed limiting protrusion 603. The limiting protrusion 603 extends from the guide groove 601 to the outside of the limiting cylinder 6. There are two moving rings 602 in the limiting cylinder 6, which are symmetrically arranged about the center of the bidirectional lead screw 604. By rotating the bidirectional lead screw 604, the moving rings 602 move within the limiting cylinder 6, thereby driving the limiting protrusions 603 to move. This makes the distance between the two moving rings 602 and the limiting protrusions 603 match the size of the cardboard, thereby preventing the cardboard from shifting position during the conveying process.

[0023] Both ends of the bidirectional lead screw 604 extend from the limiting cylinder 6. Both ends of the bidirectional lead screw 604 are fixedly installed on the rotating protrusion 605. The side of the limiting protrusion 603 that contacts the cardboard is curved. The rotating protrusion 605 facilitates the rotation of the bidirectional lead screw 604. Making the side of the limiting protrusion 603 that contacts the cardboard curved can reduce the friction between the limiting protrusion 603 and the cardboard, thereby preventing the cardboard from being unable to be conveyed.

[0024] A support cylinder 7 and an electric heating cylinder 8 are fixedly sleeved on the outer wall of the conveying roller 201 on the roller conveyor 2. Multiple support cylinders 7 and electric heating cylinders 8 are provided. The limiting cylinder 6, support cylinder 7, and electric heating cylinder 8 fill the conveying roller 201 on the roller conveyor 2. An electric slip ring 9 is fixedly installed at the end of the electric heating cylinder 8. The electric slip ring 9 is electrically connected to the electric heating cylinder 8. An electric connector 10 is fixedly installed on the inner side of the roller conveyor 2. The contact end of the electric connector 10 is electrically connected to the electric slip ring 9. The support cylinder 7 is set to support the cardboard. The electric heating cylinder 8 is set to heat the cardboard when it comes into contact with it, thereby improving the drying efficiency. The electric slip ring 9 and the electric connector 10 are set to continuously supply electrical energy to the electric heating cylinder 8.

[0025] The upper drying mechanism 3 includes a cylinder 301, which is fixedly installed on the top inner wall of the equipment housing 1. A mounting frame 302 is fixedly installed on the extended end of the cylinder 301. A heating roller 303 is installed at the bottom of the mounting frame 302. The position of the mounting frame 302 is adjusted up and down by the cylinder 301, thereby adjusting the position of the heating roller 303, so that the heating roller 303 can be as close to the paperboard as possible without contacting it, thereby improving the drying effect on the paperboard.

[0026] The exhaust gas treatment mechanism 4 includes an exhaust fan 401. The air inlet end of the exhaust fan 401 is connected to a diversion pipe 402. The end of the diversion pipe 402 away from the exhaust fan 401 is connected to a suction head 403. The suction head 403 extends into the equipment housing 1. A blower fan 5 is fixedly installed at the bottom of the roller conveyor 2. The blower fan 5 blows air upwards. The bottom of the roller conveyor 2 has ventilation holes. By blowing air onto the cardboard through the blower fan 5, moisture can be removed during the drying process, and local overheating of the cardboard can be avoided. The exhaust fan 401 sucks away the hot and humid airflow generated by drying inside the equipment housing 1, avoiding a hot and humid environment inside the equipment housing 1, which would reduce the drying efficiency of the cardboard.

[0027] The exhaust end of the vacuum pump 401 is connected to a gas purifier 11, which is located on the top of the equipment housing 1. Multiple suction heads 403 are provided and distributed in different positions inside the equipment housing 1. The vacuum pump 401 draws the hot and humid air into the gas purifier 11, which then purifies the air. Multiple suction heads 403 are provided to ensure that the hot and humid air is drawn into the gas purifier 11.

[0028] Working principle: In use, according to the size of the cardboard, rotating the rotating protrusion 605 drives the bidirectional lead screw 604 to rotate, which in turn causes the two moving rings 602 to move. Adjusting the distance between the upper limit protrusions 603 of the two moving rings 602 can match the size of the cardboard. The cardboard is placed on the roller conveyor 2. The rotation of the conveying roller 201 can synchronously reach the rotation of the limiting cylinder 6, the support cylinder 7, and the electric heating cylinder 8, thus conveying the cardboard. When the cardboard contacts the limiting cylinder 6, the limiting protrusion 603 on the limiting cylinder 6 limits the cardboard. When the cardboard contacts the electric heating cylinder 8, the electric heating cylinder 8 can initially heat the cardboard. After the cardboard is conveyed to the lower part of the upper drying mechanism 3, the heating roller 303 heats the cardboard, thus drying the cardboard.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
