[0021] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] See also Figure 1-4 The utility model provides a plastic film drying device, including a base frame 1, a drying tube 3 in an inverted concave structure is fixedly connected to the top of the base frame 1, a row of drying tubes 3 capable of blowing hot air downward is installed on the inner wall of the drying tube 3, a placement plate 4 capable of reciprocating left and right is arranged on the top of the base frame 1, and two clamping plates 5 capable of moving in opposite directions are provided on the placement plate 4. When water-based ink printing is performed, the four sides of the plastic film will be fixed by the frame to ensure that it remains stable during the printing process to prevent movement or deformation, and the frame can also help control the tension and position during printing to ensure the quality of the printing effect.

[0023] When the plastic film is printed in the frame, the frame can be directly placed on the placement plate 4, and the two clamping plates 5 can be moved toward each other to fix the frame on the surface of the placement plate 4. At this time, the placement plate 4 can move back and forth left and right, so that the placement plate 4 can drive the plastic film in the frame to continuously move through the bottom of the drying tube 3. The hot air blown out by the drying tube 3 can be in close contact with the surface of the plastic film, thereby achieving an efficient and uniform drying effect on the surface of the plastic film.

[0024] See also Figure 4 A slide groove 6 is provided at the top of the placement plate 4 , and a slider 7 inserted into the slide groove 6 is formed at the bottom of the two clamping plates 5 , so that the two clamping plates 5 can form a sliding connection at the top of the placement plate 4 .

After the staff places the frame with a plastic film inside on the placement plate 4, they can hold the handle 9 by hand and rotate it, so that the bidirectional threaded rod 8 can drive the two sliders 7 to slide toward / oppositely along the slide groove 6 through the cooperation of the forward thread and the reverse thread, so that the two clamps 5 can clamp / release the frame.

[0026] Specifically, fixed blocks 10 are fixedly connected at the four corners of the top of the base frame 1, a guide rod 11 is fixedly connected between every two left-right symmetrical fixed blocks 10, and connecting plates 12 slidably sleeved on the corresponding guide rods 11 are fixedly connected on both sides of the placement plate 4, so that the placement plate 4 can form a sliding connection on the base frame 1 along its length direction. Such a design will be more reasonable.

[0027] In order to enable the placement plate 4 to move back and forth left and right, it is proposed that a connecting block 14 is fixedly connected to one side of the placement plate 4, and a guide groove 13 that penetrates it is opened at the top of the base frame 1 along its length direction. A circular plate 15 with a vertical axis is provided in the base frame 1, and a push rod 16 is rotatably connected to the top non-center of the circular plate 15. The push rod 16 is fixedly connected to a connecting shaft 17 away from the side connected to the circular plate 15. The top of the connecting shaft 17 penetrates the guide groove 13 and is fixed to the bottom of the connecting block 14. A driving member for driving the circular plate 15 to rotate is provided on the base frame 1. When the circular plate 15 rotates, one side of the push rod 16 can rotate along its axial direction, and the other side of the push rod 16 can drive the connecting shaft 17 to reciprocate along the guide groove 13, and the connecting shaft 17 will push the placement plate 4 to move back and forth on the base frame 1, so that the plastic film on the placement plate 4 will move synchronously, so that the drying tube 3 can evenly dry the surface of the film.

[0028] See also Figure 2 The driving member includes a motor 18 fixedly installed in the base frame 1 with the output shaft facing upward. The end of the output shaft of the motor 18 is fixedly connected to the bottom center of the circular plate 15. When the output shaft of the motor 18 rotates, the circular plate 15 can be driven to rotate.

[0029] Furthermore, a hot air duct 19 connected to the inside of each drying tube 3 is inserted at the top of the mounting frame 2, and the hot air duct 19 can transport hot air to the inside of each drying tube 3, so that the hot air can be blown toward the surface of the plastic film through the drying tube 3 to achieve a drying effect.
