Description

Technical Field

[0001] The utility model relates to the technical field of pulp molded products, in particular to a drying device for producing pulp molded products. Background Art

[0002] Paper-plastic molding pulp is a three-dimensional pulping technology that uses waste paper as raw material and shapes paper products of a certain shape on a molding machine through a special mold. Pulp molded products are solid containers used to contain and limit the packaged objects, serving the circulation, storage and transportation of goods, that is, they are mainly used for the transportation and packaging of goods. After the pulp molded products are formed, they contain a large amount of moisture, which needs to be removed by drying to facilitate shaping and use. The existing pulp molded product drying device needs to place the pulp molded products on a conveyor belt body for drying. During the drying process, if the drying wind force is too strong, the pulp molded products are easily blown off the conveyor belt body. In addition, during drying, the drying wind is always transported upward from the bottom of the drying box, resulting in uneven drying and heating of the pulp molded products. Utility Model Content

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1-3 A drying device for pulp molded product production includes a drying box 1, a first support frame 2 is provided inside the drying box 1, a first conveyor belt body 3 is rotatably provided on the first support frame 2, and a second conveyor belt body 4 is movably provided above the first conveyor belt body 3;

[0023] A first drying device is provided below the first conveyor belt body 3 , and a second drying device is provided above the second conveyor belt body 4 ; an exhaust device is provided on the top of the drying box 1 .

[0024] A plurality of height-adjusting cylinders 5 are vertically arranged upward on the first support frame 2 , a second support frame 6 is fixed on the piston rod of the height-adjusting cylinder 5 , and the second conveyor belt body 4 is rotatably arranged on the second support frame 6 .

[0025] In this embodiment, the product to be dried is placed on the first conveyor belt body 3, and then the height adjustment cylinder 5 is started to make the second conveyor belt body 4 contact with the top of the product, and the first conveyor belt body 3 and the second conveyor belt body 4 are started to convey to the right. Through the above operation, the product can be prevented from being blown off the conveyor belt body during drying;
