Brand new particles are used to blow out new materials with uniform color, cleanness, and good bag stretching. After the film blowing operation, the plastic bags need to be treated with a drying device to remove moisture from their surface. The drying device, also known as a dryer or dryer, is a device used for drying operations. It vaporizes and releases moisture (generally water or other volatile liquid components) in the material by heating to obtain a solid material with a specified moisture content.

[0003] The drying device is of electric heating blower type, which blows the received heat to the surface of the plastic bag through the blower, and contacts with the moisture on the surface of the plastic bag to achieve the effect of drying the plastic bag. However, the plastic bag is transported at a relatively fast speed after film blowing, and the plastic bag stays in the drying device for a relatively short time, so the plastic bag is not dried effectively, and a small amount of water stains may still remain on the surface of the plastic bag, reducing the efficiency of the drying device. Therefore, it is particularly important to design a drying device for film blowing plastic bags, which can be repeatedly wiped with the surface of the plastic bag after drying. Utility Model Content

[0004] The utility model aims to provide a drying device for blown film plastic bags to solve the problem in the background art that the plastic bags after film blowing are conveyed at a relatively fast speed, the plastic bags stay in the drying device for a relatively short time, and thus the drying effect of the plastic bags is poor.

A convex plate 12 is provided, a shelf 16 is provided on one side of the extrusion plate 5, one end of the return spring 11 is fixedly connected to the top of the moving block 7, and the other end of the return spring 11 is fixedly connected to the outer wall of the fixed column 6. The raised portion of the cam 15 will gradually exert an upward force on the bottom of the convex rod 13, thereby driving the moving block 7 to move upward at one end of the fixed column 6. A plastic bag is passed between the two wiping plates 9, and the surfaces of the multiple fluffs 10 rub against the surfaces of the plastic bags respectively. During the up and down movement of the wiping plates 9, the surfaces of the multiple fluffs 10 are constantly and repeatedly wiped against the surface of the plastic bag.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, the output shaft of the servo motor 14 is transmission-connected with a cam 15, and the cam 15 is located at the bottom of the convex rod 13. One side of the two wiping plates 9 is fixedly connected to the two sides of the vertical rod 8 respectively, and one end of the plurality of villi 10 is fixedly and interlacedly connected to the other side of the two wiping plates 9 respectively. The utility model is a drying device for blown film plastic bags. By setting a drying box 3, a moving block 7, a reset spring 11 and a vertical rod 8, the drying box 3 is of an electric heating blast type. The plastic bags after film blowing will be transmitted to the interior of the drying box 3, and then the heat transmitted by the blower will contact with the moisture on the surface of the plastic bags, so as to achieve the purpose of drying.

[0026] Working principle: The film blowing machine heats and melts plastic particles and then blows them into a film. After the film blowing operation, the plastic bag needs to use a drying device to deal with the moisture on its surface. The drying device is also called a dryer and a dryer, which is a device used for drying operations. The film blowing motor 2 can mainly blow the plastic bag into shape, and then convey the shaped plastic bag to the inside of the drying box 3. After the drying process, one side of the plastic bag continues to be rolled up and conveyed by the winding roller 4, that is, after the plastic bag is rolled up on the surface of the winding roller 4, it can continue to be conveyed to the bottom of the drying rack 1 and conveyed to the next process for continuous operation. At this time, the plastic bag wound and rolled on the surface of the winding roller 4 is inserted into the middle position of the two wiping plates 9, the purpose is to be repeatedly rubbed by multiple fluffs 10 again, so that the water stains on its surface continue to be wiped, and the drying effect continues to be achieved. In order to increase the range of wiping water stains on the surface of the plastic bag, the staff can start the servo motor 14 at the same time. After starting the servo motor 14, it will drive the cam 15 to rotate in a circle, and the raised part of the cam 15 will gradually contact the convex rod The bottom of 13 exerts an upward force, thereby driving the moving block 7 to move upward at one end of the fixed column 6, and the plastic bag is passed between the two wiping plates 9, and the surfaces of the multiple villi 10 rub against the surfaces of the plastic bags respectively. In the process of the wiping plates 9 moving up and down, the surfaces of the multiple villi 10 are constantly and repeatedly wiped against the surface of the plastic bags, so that the water stains on the surface can be wiped clean, thereby improving the efficiency of the drying device. The drying box 3 is an electric heating blast type. The plastic bags after film blowing will be transmitted to the inside of the drying box 3, and then the heat transmitted by the blower will contact with the moisture on the surface of the plastic bags, so as to achieve the purpose of drying. The plastic bags are wound on the surface of the winding roller 4 and continue to be transmitted to the bottom of the drying rack 1. When the moving block 7 moves upward, the return spring 11 is compressed and deformed by force. When the moving block 7 is not subjected to force, the return spring 11 returns to its initial state, driving the moving block 7 to continue to move downward. The moving block 7 is fixed to the wiping plate 9 by the vertical rod 8. The up and down movement of the wiping plate 9 increases the range of wiping water stains on the surface of the plastic bag.
