[0028] The present utility model provides a particle dryer for breathable film production through improvement, and its working principle is as follows;

[0029] First, when using this equipment, first place this device in the working area, and then connect the device to an external power supply to provide the electric energy required for the operation of this equipment;

[0030] Second, first place a sufficient amount of materials inside the material frame 11, then slidably connect the material frame 11 with the limit frame 10 to place the material frame 11 into the device. Then, start the double-shaft motor 52 through the control board 3. The double-shaft motor 52 will drive the wire winding roller 53 to rotate through the output shaft. The wire winding roller 53 will lower the connecting wire 54 so that the fixed frame 56 can move to the top surface of the material frame 11. At the same time, the positioning magnets 58 at the four corners of the fixed frame 56 will align and adsorb with the limit magnets at the four corners of the top of the material frame 11, so that the fixed frame 56 is limited on the top of the material frame 11 to prevent the fixed frame 56 from detaching when the material frame 11 vibrates. After completing the above operations, close the box door of the device. Start the air outlet air box 2 and the hot air blower 4 through the control board 3. The hot air blower 4 will spray dry air into the device through the spray pipe 7, and the air outlet air box 2 will perform air outlet operation on the device, so that an upward flowing drying air flow can be formed inside the device to enhance the drying effect on the materials. Then, start the vibration motor 12 through the control board 3, so that the vibration motor 12 drives the limit frame 10 and the material frame 11 to vibrate along the buffer spring 9, so that the materials can jump differently inside the material frame 11, so that the drying air flow can dry each particle of material and increase the uniformity of drying;

[0031] Third, during the drying process, the combing mechanism 6 will operate regularly. First, the first cylinder 66 will be started. The first cylinder 66 drives the connecting block 67 to move downward to the inner bottom surface of the material box 11 through the telescopic rod. Then the second cylinder 68 will be started. The second cylinder 68 drives the sliding sleeve 610 to perform a forward and backward unfolding action along the limiting column 69 through the telescopic rod. Then the motor 611 will be started. The motor 611 drives the two-way threaded rod 64 to rotate through the meshing transmission of the gears in the transmission box 63, and then the two-way threaded rod 64 drives the two moving blocks 65 to move towards or away from each other. The moving blocks 65 will drive the components below them to perform a certain degree of combing work on the materials piled up together, so as to avoid the materials piling up together and thus affecting the overall drying efficiency.

[0032] The utility model provides a particle dryer for breathable film production through improvement. By arranging the anti-leakage mechanism 5 inside the drying box 1, before drying the material box 11, the fixed frame 56 is moved downward along the connecting line 54 through the cooperation of the double-shaft motor 52 and the wire winding roller 53, so that the positioning magnets 58 at the four corners of the fixed frame 56 are aligned with and adsorbed to the limiting magnets at the four corners of the top of the material box 11, thereby limiting the fixed frame 56 on the top of the material box 11 and completing the closing of the top of the material box 11. The filter screen 57 arranged inside the fixed frame 56 can avoid the problems that the materials inside the material box 11 are scattered or fall to various parts inside the device when the material box 11 vibrates during drying, and at the same time can avoid some impurities driven by the air jet pipe 7 when drying and jetting air inside the device from entering the material box 11, avoiding material contamination and increasing the overall drying efficiency; by arranging the combing mechanism 6 in the middle end of the fixed frame 56 of the anti-leakage mechanism 5, when the material box 11 is affected by the vibration motor 12, the materials inside it may pile up due to vibration, thus affecting the drying efficiency. Therefore, during the drying process, the combing mechanism 6 will be started regularly to comb the materials piled up inside the material box 11 to a certain extent. The first cylinder 66 drives the connecting block 67 and the components on its front and rear sides to move downward to the inner bottom surface of the material box 11, then the second cylinder 68 drives the sliding sleeve 610 to unfold on the front and rear sides along the limiting column 69, and then the moving block 65 moves along the two-way threaded rod 64 through the cooperation of the transmission box 63 and the motor 611, thereby completing the combing of the materials piled up inside the material box 11 and avoiding the occurrence of reduced drying efficiency and uneven drying caused by material piling.
