[0017] The technical solution of this utility model will be further described below through embodiments and in conjunction with the accompanying drawings.
[0018] Example:
[0019] This embodiment describes a tape drying device, such as... Figure 1 and Figure 2 As shown, the device includes a drying chamber 1. The left and right ends of the drying chamber 1 are respectively provided with a tape inlet and a tape outlet. Several variable diameter drying mechanisms 4 are provided between the tape inlet and the tape outlet. The tape 2 to be dried passes through each variable diameter drying mechanism in sequence. The upper and lower sides of the drying chamber 1 are respectively provided with an air outlet 5 and a return air outlet 6. The drying chamber 1 is provided with a pipe for connecting the air outlet 5 and the return air outlet 6. A fan 8 is provided on the pipe.
[0020] like Figures 1 to 4As shown, the variable diameter drying mechanism 4 includes a turntable 15, a drive wheel 3, a base 10, a sliding rod 12, and an electric heating tube 14. The base 10 is fixedly mounted on the front and rear inner walls of the drying chamber 1. The base 14 has several grooves 11 arranged in a ring. The sliding rod 12 is slidably mounted in the grooves 11. The turntable 15 is rotatably mounted on the base 10. The turntable 15 has several arc-shaped grooves 16 arranged in a ring. The first end of the sliding rod 12 is provided with a limiting post 13, which is slidably mounted in the arc-shaped groove 16. The two ends of the electric heating tube 14 are fixedly mounted on the second ends of two opposing sliding rods 12. The drive wheel 3 meshes with the turntable 15. The drive wheel is driven by a drive motor 9. The drive motor 9 is fixedly mounted on the outer wall of the drying chamber 1. The output shaft of the drive motor 9 passes through the wall of the drying chamber and is connected to the drive wheel. In this embodiment, the base 10 is cross-shaped, with a bearing in the middle. The turntable 15 is rotatably connected to the base 10 via the bearing. Slide grooves 11 are provided on each support arm of the base 10, and arc-shaped grooves 16 correspond one-to-one with slide grooves 11. When the drive motor drives the drive wheel to rotate, the drive wheel drives the turntable to rotate. When the turntable rotates, the position of the arc-shaped grooves changes, causing the sliding rod to slide along the slide grooves, thereby changing the distance between the electric heating tube and the tape to be dried.
[0021] Furthermore, several sets of air outlets 5 and return air inlets 6 are provided, each corresponding to one of the variable-diameter drying mechanisms 4. A drying chamber 7 is located between the return air inlet 6 and the fan 8. In addition, a filter screen is provided between the fan and the drying chamber. The arrangement of the air outlets and return air inlets allows air circulation, ensuring uniform temperature in the drying chamber. Furthermore, in conjunction with the drying chamber, it can remove moisture from the drying chamber, reduce humidity, and thus improve drying efficiency.
[0022] In this embodiment, the tape drying device is used by passing the tape to be dried sequentially through the tape inlet, each diameter-changing drying mechanism, and the tape outlet. At this point, electric heating tubes are located on both the top and bottom of the tape, enabling double-sided drying. During the drying process, the drying temperature can be adjusted by regulating the power of each electric heating tube, and the distance between each heating tube and the tape can be adjusted by the drive motor. When the heating tube temperature is too high, the drive motor operates to move the heating tubes away from the tape, preventing the tape substrate from melting; when the heating tube temperature is too low, the drive motor operates to move the heating tubes closer to the tape, ensuring drying efficiency. Furthermore, depending on the application and type of the tape, the tape substrate, adhesive type, and coating amount will vary. Two types of tapes with the same substrate and adhesive but different adhesive application amounts may exist. The drying temperature is mainly adjusted based on the tape substrate. If the electric heating tube is maintained at a suitable temperature and in a fixed position, the drying time of the two tapes will also differ due to the difference in adhesive application amount. This requires the factory to adjust the upstream and downstream conveying equipment of the drying device. However, the tape drying device in this embodiment can use a drive motor to move the electric heating tube closer to or further away from the tape to be dried, so that the two tapes with different adhesive application amounts can have similar drying times under the premise that the electric heating tube is at the same temperature. This avoids the problem of adjusting the speed of the upstream and downstream conveying equipment of the drying device.
[0023] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
