Description

Technical Field

[0001] This utility model relates to the technical field of raw material drying, specifically a raw material drying device for packaging film production. Background Technology

[0002] Packaging film mainly refers to thin films used for packaging goods, primarily food, pharmaceuticals, and textiles. Packaging film requires water cooling; if the water droplets adhering to the surface after cooling are not dried, it will affect the subsequent packaging and processing of the packaging film. Therefore, a drying device is required.

[0003] Currently available raw material drying equipment for packaging film production suffers from uneven drying, resulting in incomplete drying of the packaging film. This affects subsequent packaging film production and causes the packaging film to stick together due to moisture, which in turn affects the production quality of the packaging film and reduces the practicality of the drying equipment.

[0004] Therefore, it is necessary to provide a raw material drying apparatus for packaging film production to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of the present invention, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0005] The purpose of this invention is to provide a raw material drying device for packaging film production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A raw material drying device for packaging film production includes a drying chamber. Temperature sensors are installed on both sides of the inner cavity of the drying chamber. A heating chamber is installed on the right side of the drying chamber. Horizontal plates are installed on the top of both sides of the inner cavity of the heating chamber. A hot air blower is installed on the top of the horizontal plates. A guide pipe is connected to the front of the hot air blower. The side of the guide pipe away from the hot air blower passes through the front of the heating chamber and is connected to a conduit. A connecting pipe is connected to the left side of the conduit via a pipe. A conveying pipe is connected to the back of the connecting pipe and the conduit through both sides of the inner cavity of the drying chamber. An air outlet hood is connected to the inner side of the conveying pipe from top to bottom. An air suction pipe is connected to the bottom of the hot air blower. The bottom of the air suction pipe passes through the bottom of the horizontal plate and is connected to an air suction hood. Heating pipes are arranged horizontally at the bottom of the air suction hood. The two sides of the heating pipes are fixed to the two sides of the inner cavity of the heating chamber. An air inlet pipe is connected to the bottom of the heating chamber. A dust collection filter plate is arranged horizontally inside the air inlet pipe.

[0008] Preferably, the bottom of the hot air blower is equipped with a bracket, and the bottom of the bracket is fixed to the top of the horizontal plate.

[0009] Preferably, a guide roller 1 is installed on the right side of the top of the drying box via a fixing frame, and guide roller 2 is installed on the bottom of the left side and the bottom of the right side of the inner cavity of the drying box via a fixing frame.

[0010] Preferably, guide rollers three are provided on the top of both sides of the inner cavity of the drying box, and the outer sides of the guide rollers three are fixed to both sides of the bottom of the inner cavity of the drying box by a fixing frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The temperature value of the temperature sensor is set by an external controller. When the temperature is lower than or higher than the set temperature value, the external controller starts and stops the heating element. The heating element and hot air blower are also activated by the external controller. The hot air blower draws air through the suction pipe and suction hood. The air intake pipe filters the external airflow through a dust collection filter and introduces it into the heating chamber. The heating element inside the heating chamber heats the incoming airflow. Simultaneously, the suction hood and suction pipe transport the hot air to the outlet pipe. The outlet pipe, through a conduit, pipe, and connecting pipe, transports the hot air to the conveying pipe. The conveying pipe then transports the hot air through the outlet hood into the drying chamber, ensuring that the hot air is evenly distributed within the drying chamber. Simultaneously, the packaging film material enters the drying chamber through guide rollers one, two, and three. The hot air evenly dries the packaging film material entering the drying chamber, ensuring uniform drying of both sides. Automatic temperature control can be implemented according to actual conditions, preventing resource waste. Attached Figure Description
