[0043] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0044] Example:

[0045] See also Figure 1-Figure 5 A bamboo pulp paper drying machine includes a cabinet 1, a storage rack 2, a heat flow pipe 3, a fan 4 and a guide plate 5, wherein a plurality of support frames 6 are arranged inside the cabinet 1, the support frames 6 are horizontally placed inside the cabinet 1, and all the support frames 6 are distributed in the vertical direction. In the vertical direction, there is a spacing between adjacent support frames 6. In addition, the front side of the cabinet 1 is in an open state;

[0046] A plurality of racks 2 are arranged in the cabinet 1, and a rack 2 is slidably arranged on each support frame 6, and the rack 2 slides into the cabinet 1 from the opening of the front side of the cabinet 1. In addition, the rack 2 has a plurality of holes.

[0047] The heat flow pipe 3 is arranged at the bottom of the cabinet 1. The heat flow pipe 3 is arranged on a horizontal plane, and a fan 4 is provided at the bottom of the heat flow pipe 3. The air flow output by the fan 4 will pass through the heat flow pipe 3 and flow into the interior of the cabinet 1, bringing the heat on the heat flow pipe 3 to the interior of the cabinet 1.

[0048] There is a distance between the fan 4 and the heat flow tube 3, and a plurality of guide plates 5 are arranged in the distance. All the guide plates 5 form a trumpet-shaped structure, and the end with a small opening of the trumpet-shaped structure is installed on the fan 4, and the end with a large opening is close to the heat flow tube 3.

[0049] In this embodiment, the rack 2 is movably arranged in the cabinet 1, and when drying, the paper can be placed on the rack 2. The heat in the heat flow pipe 3 is blown to the upper part of the cabinet 1 by the fan 4 arranged at the bottom of the cabinet 1 to achieve the drying effect on the paper. Since the heat is conducted to the upper part of the cabinet 1 by the airflow, the drying temperature will not be too high during the drying process and is easy to control.

[0050] In addition, by arranging a guide plate 5 around the fan 4, the blown airflow is dispersed to different positions in the cabinet 1 through the guide plate 5, so as to achieve the purpose of uniform heating.

[0051] Preferably, the dryer further comprises a cylinder 7, wherein the cylinder 7 is arranged on the side of the cabinet 1, the length direction of the cylinder 7 is in the horizontal direction, and the piston rod end of the cylinder 7 is connected to one end of the rack 2, so that the rack 2 is driven to move in the cabinet 1 by the cylinder 7.

[0052] Generally, cylinders 7 are symmetrically arranged on both sides of the cabinet 1, and both sides of the end of each shelf 2 are respectively connected to the piston rod end of a cylinder 7, so that each shelf 2 is synchronously driven by two cylinders 7. By symmetrically arranging the same number of cylinders 7 on both sides of the cabinet 1, each shelf 2 can be pushed out of the cabinet 1 or put into the cabinet 1 individually.

[0053] In one specific embodiment:

[0054] The storage rack 2 includes a storage plate 21, a baffle 22 and a support rod 23. The storage plate 21 has a plurality of holes, which facilitate the passage of airflow. The baffle 22 is disposed on one end of the storage plate 21, and the end of the baffle 22 is fixedly connected to the middle of the storage plate 21, so that the plate surface of the baffle 22 is perpendicular to the plate surface of the storage plate 21.

[0055] In addition, both ends of the baffle 22 are fixedly connected to the end of the piston rod of a cylinder 7 respectively.

[0056] One end of the support rod 23 is fixedly arranged on the baffle plate 22, and the baffle plate 22 is located on the bottom surface of the storage plate 21. At the same time, a plurality of support rods 23 parallel to each other are fixedly arranged on the bottom surface of the baffle plate 22. All the support rods 23 are slidably arranged on the support frame 6.

[0057] In this embodiment, the storage plate 21 is supported by the support rod 23, and the baffle 22 is used to connect the cylinder 7. Moreover, when all the storage racks 2 are located in the cabinet 1, all the baffles 22 can completely cover the side of the cabinet 1 that is in an open state, thereby preventing the heat in the cabinet 1 from leaking out.

[0058] In another specific embodiment:

[0059] A plurality of heat flow pipes 3 are arranged at the bottom of the cabinet 1, and the heat flow pipes 3 are U-shaped structures. All heat flow pipes 3 are evenly arranged at the bottom of the cabinet 1 and are located on the same plane. A heating plate 8 is arranged on each heat flow pipe 3, and the heat flow pipe 3 can be heated by the heating plate 8, and the heat flow pipe 3 transfers the temperature to the bottom of the entire cabinet 1, and then the fan 4 transfers the heat to the inside of the entire cabinet 1.

[0060] Preferably, the heat flow pipe 3, the heating plate 8, the fan 4 and the guide plate 5 are arranged in a box with an open top, and the box is arranged at the bottom of the cabinet 1. This is to facilitate the management of the heat flow pipe 3, the heating plate 8, the fan 4 and the guide plate 5.

[0061] In another specific embodiment:

[0062] The guide plate 5 is a trapezoidal structure, with one short side fixed to the side of the top surface of the fan 4 . The guide plate 5 is arranged on the fan 4 in an inclined state, and four guide plates 5 are arranged around the fan 4 .

[0063] The fan 4 includes a motor 41, a connecting plate 42 and blades 43. The motor 41 is fixedly arranged at the bottom of the cabinet 1, generally arranged in the box, and the output shaft of the motor 41 is in a vertically upward state. The connecting plate 42 is a circular structure, and the connecting plate 42 is fixedly arranged on the output shaft of the motor 41. At the same time, the plate surface of the connecting plate 42 is vertically connected to the output shaft of the motor 41, and the connecting plate 42 is coaxially arranged with the output shaft of the motor 41. There are a plurality of blades 43 arranged on the connecting plate 42, and the blades 43 are plate-shaped structures, the plate surface of the blades 43 is perpendicular to the plate surface of the connecting plate 42, all the blades 43 are distributed around the output shaft of the motor 41, and all the blades 43 are close to the edge of the connecting plate 42.

[0064] In this embodiment, the motor 41 drives the connecting plate 42 and the fan blades 43 to rotate, generates airflow through the fan blades 43, guides the airflow from the periphery of the box into the middle thereof through the connecting plate 42, and then drives the airflow into the box by the fan blades 43.

[0065] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
