Description

Technical Field

[0001] This utility model relates to the field of paper technology, and more specifically, to a paper feeding and cutting mechanism for a paper dryer. Background Technology

[0002] Paper is a thin sheet made from plant fibers. Paper production can be done by machine or by hand. During the use of paper, it usually needs to be dried.

[0003] After searching, it was found that application number CN202322780205.3, entitled "A Paper Dryer", proposed a paper drying device that uses a processing box to heat dry paper. The processing box has a feed port at one end. When feeding the paper, the operator needs to insert one end of the paper into the feed port. Since one end of the paper is relatively soft, the operator needs to put their hand into the feed port to complete the installation with the processing box, which is very troublesome. At the same time, when the paper breaks, the operator needs to manually use a cutter to cut the paper, which is still quite troublesome. Further improvements can be made.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a paper feeding and cutting mechanism for a paper dryer, which has the advantages of improved ease of use and convenient paper cutting, thereby solving the problems mentioned in the background technology.

[0006] To achieve the aforementioned advantages of improved ease of use and convenient paper cutting, the specific technical solution adopted by this utility model is as follows:

[0007] A paper feeding and cutting mechanism for a paper dryer includes a paper feeding frame and a drive roller. The drive roller is rotatably connected inside the paper feeding frame, and a conveyor belt is sleeved on the outside of the drive roller. A drive motor is fixedly installed on the front of the paper feeding frame, and the output end of the drive motor is fixedly connected to one end of the roller shaft of the drive roller. A second electric cylinder is fixedly installed on the top surface of the paper feeding frame, and a lifting frame is fixedly installed on the bottom surface of the moving rod of the second electric cylinder. A roller frame is fixedly installed on the bottom surface of the lifting frame. A pressure roller is rotatably connected between the roller frames. An extension plate is fixedly installed inside the paper feeding frame on one side of the conveyor belt, and a knife groove is opened on the top surface of one end of the extension plate. A cylinder is fixedly installed on the top surface of the paper feeding frame, and a knife holder is fixedly installed on the bottom surface of the piston rod of the cylinder. A cutter is fixedly installed on the bottom surface of the knife holder.

[0008] Furthermore, the cutter is located directly above the cutter groove, and the width of the cutter is greater than the width of the paper.

[0009] Furthermore, the surface of the extension plate is provided with ventilation holes, which are densely distributed at equal intervals.

[0010] Furthermore, the top surface of the extension plate is polished.

[0011] Furthermore, a guide rod is fixedly installed on the top surface of the lifting frame, and the guide rod passes through the paper guiding frame and is slidably connected to the paper guiding frame.

[0012] Furthermore, a base plate is installed below the paper feeding frame, and a first electric cylinder is vertically installed between the base plate and the paper feeding frame.

The extension plate extends into the drying mechanism. When guiding the paper, one end of the paper can be placed on the top surface of the conveyor belt. The second electric cylinder and the drive motor are started. The second electric cylinder extends and pushes the pressure roller down to press one end of the paper. Then, the drive motor drives the drive roller to rotate, drives the conveyor belt to rotate, and then drives one end of the paper to move to guide the paper. The paper moves on the top surface of the extension plate into the drying mechanism of the dryer. The operator only needs to guide one end of the paper and put it on the top surface of the conveyor belt to automatically guide the paper, which saves the operator the trouble of reaching into the drying mechanism to guide the paper and improves the convenience of use.
