Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, and in particular to a drying device. Background Technology

[0002] Plastic, as a commonly used material, is widely used in the packaging industry. Plastic materials have the characteristics of good flexibility, high tensile strength, and light weight. During the production and processing of plastic bags, the printed patterns on the packaging bags are dried using drying equipment. To ensure the physical and mental health of workers, existing drying equipment uses adsorption components to treat the pollutants generated during drying, thus ensuring the physical and mental health of workers to a certain extent. However, although this ensures the physical and mental health of workers to a certain extent, the surface of the packaging bags may wrinkle during drying, which greatly reduces the drying efficiency.

[0003] A search revealed a Chinese patent document (authorization announcement number CN217476858U), which discloses a drying device for printing packaging bags. The device includes a box and a filter assembly. Pipes are arranged on both sides of the box, and the filter assembly is installed inside the pipes. The filter assembly includes a storage box, a cover, activated carbon, a push block, and a push rod. The cover is rotatably connected to the upper end of the storage box. Activated carbon is placed inside the storage box, and a push block is located at the lower end of the activated carbon. A push rod is fixedly connected to the bottom end of the push block. Exhaust fans are installed at the center of both ends of the inner wall of the box. This drying device for printing packaging bags can remove odors, preventing operators from inhaling odors for extended periods and causing health problems. While this patent protects the health of workers to some extent, the surface of the packaging bags may wrinkle during drying, significantly reducing drying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device, including a drying chamber, a drying component installed on the side of the drying chamber, and a processing component for drying gas treatment installed on the side of the drying chamber. A fixed end of an electric push rod is installed at the top of the drying chamber, and an installation box is fixedly connected to the inner side of the drying chamber via a connecting block. A guide rod is fixedly connected to the inner side of the installation box. Two symmetrical guide blocks are slidably connected to the outer periphery of the guide rod, and a movable rod is hinged to the top of the guide blocks via a hinge. A support column is hinged to the end of the movable rod away from the guide blocks, and the top of the support column is fixedly connected to the driving end of the electric push rod. A connecting plate is fixedly connected to the side of the guide blocks, and one end of the connecting plate passes through a limiting groove on the side of the installation box and is fixedly connected to a limiting box. A two-section screw is rotatably connected to the inner side of the limiting box, and a drive motor for providing power to the screw is installed at the top of the limiting box. Two adjusting blocks are threadedly connected to the outer periphery of the screw, and a positioning plate is fixedly connected to the end of the adjusting block located outside the limiting box.

[0006] Preferably, the drying chamber has two symmetrical material troughs on both sides.

[0007] Preferably, the drying assembly includes a mounting box installed on the side of the drying chamber and two fans embedded in the side of the mounting box.

[0008] Preferably, the inner side of the mounting box is equipped with multiple heating wires, and the side of the mounting box is connected to the drying box through a connecting air duct and a drying hood.

[0009] Preferably, the inner side of the drying oven is equipped with the fixed end of a linear motor, and the drive end of the linear motor is connected and fixed to the drying hood.

[0010] Preferably, the processing assembly includes an exhaust fan mounted on the side of the drying chamber and a processing box mounted on the top of the drying chamber.

[0011] Preferably, the exhaust fan's outlet is connected to the processing box via a pipe, and activated carbon for treating the dry gas is installed inside the processing box, while an exhaust hood is connected to the side of the processing box.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are:

[0013] This drying device, thanks to the design of the electric push rod and processing components, adjusts the movable rod at the bottom of the support column by activating the electric push rod. The movement of the movable rod causes the guide block to move along the extension direction of the guide rod. The opposing movement of the guide blocks causes the two limiting boxes on the side of the connecting plate to move towards each other. Furthermore, activating the drive motor drives the screw to rotate. The rotation of the screw causes the two positioning plates to clamp the edge of the packaging bag. Activating the electric push rod causes the support column to rise, causing the two limiting boxes to move in opposite directions to achieve a straightening effect. Compared with the existing drying methods, this device can prevent the packaging bag from wrinkling, ensuring the drying efficiency of the device. Moreover, the design of the processing components can treat the gases generated during drying, ensuring the physical and mental health of the workers.

[0014] This drying device can prevent the packaging bags from wrinkling, effectively ensuring the drying efficiency of the device. Attached Figure Description

[0031] Working principle

[0032] In operation, the drying device involves loading the packaging bag, activating the electric push rod 4 to adjust the movable rod 14 at the bottom of the support column 15, and moving the movable rod 14 to move the guide block 13 along the extension direction of the guide rod 12. The opposing movement of the guide blocks 13 causes the two limiting boxes 7 on the side of the connecting plate 6 to move in opposite directions. The drive motor 8 is activated to rotate the screw 10, which causes the two positioning plates 9 to clamp the edge of the packaging bag. The electric push rod 4 is activated to raise the support column 15, causing the two limiting boxes 7 to move in opposite directions to straighten them. The fan 21 and heating wire 23 are activated for drying, and the linear motor 24 is activated to move the drying hood 25 back and forth. During the drying process, the exhaust fan 32 is activated to draw the drying gas into the processing box 31, where it is adsorbed by the activated carbon 34.
