A screening screen 4 is fixedly connected to the inner wall of the shell 1. A hollow column 5 is rotatably connected to the shell 1. Multiple equally spaced cutting blades 6 are fixedly connected to the outer wall of the hollow column 5, capable of cutting small-volume plastic products into granules. A motor 7 is fixedly connected to the outer wall of the shell 1. A transmission rod 8 is fixedly connected to the output end of the motor 7. A synchronous belt 9 is fitted together on the outer wall of the hollow column 5 and the outer wall of the transmission rod 8. An electric hot air blower 11 is fixedly connected to the front end of the shell 1. The air outlet of the electric hot air blower 11 is connected to a connecting pipe. A rotary joint 10 is installed together with the bottom of the hollow column 5 on the connecting pipe. An exhaust mechanism is provided on the shell 1.

[0022] It should be noted that: two crushing motors are installed on the outer wall of the housing 1. The output shaft of each crushing motor is coaxially and fixedly connected to its corresponding crushing roller 3. The crushing motor can drive the two crushing rollers 3 to rotate in the same direction to crush the plastic products, which facilitates the subsequent cutting and granulation processing.

[0023] The exhaust mechanism includes a through-hole that penetrates the housing 1. An intercepting net 13 is fixedly connected to the inner wall of the through-hole to intercept particulate products and prevent them from escaping. A frame plate 14 is fixedly connected to the outer wall of the housing 1. A transmission rod 8 passes through the frame plate 14 and is rotatably connected to it. A driving bevel gear 15 is fixedly connected to the top of the transmission rod 8. The driving bevel gear 15 meshes with a driven bevel gear 16. A rotating rod 17 is fixedly connected to the driven bevel gear 16 on the same axis. A fan 18 is fixedly connected to the end of the rotating rod 17. A limiting plate is fitted on the outer wall of the rotating rod 17 and is rotatably connected to it. The limiting plate is fixedly connected to the inner wall of the frame plate 14.

[0024] It should be noted that the rotation of fan 18 can expel water vapor inside the casing 1 to the outside with the air, thereby achieving dehumidification inside the casing 1 and providing excellent drying effect for the product.

[0025] Multiple through holes are provided on the outer wall of the hollow column 5, and the multiple through holes are distributed at equal intervals.

[0026] It should be noted that hot air is discharged through multiple holes and comes into contact with the cut product to dry it.

[0030] The outer wall of the housing 1 is fixedly connected with four L-shaped support legs that are arranged in a rectangular pattern.

[0031] The working principle of the granulator provided by this utility model is as follows: The operator injects plastic products into the housing 1 through the feed hopper 2.

The motor 7 is started, and its output drives the transmission rod 8, synchronous belt 9, hollow column 5, and multiple cutting blades 6 to rotate, cutting the crushed plastic products into granules. The granules are then screened through a sieve 4 until the diameter meets the requirements, at which point they fall through the sieve 4 and the discharge hopper 12 for collection. During cutting, the motor 7 starts... The electric hot air blower 11 generates hot air which is discharged through the connecting pipe, hollow column 5, and multiple through holes. It can heat and dry the cut granular products, heating the moisture adhering to the plastic products until it becomes water vapor. The output end of the motor 7 drives the transmission rod 8, the driving bevel gear 15, the driven bevel gear 16, the rotating rod 17, and the fan 18 to rotate, which can discharge the air in the shell 1 to the outside through the frame plate 14 and discharge the water vapor with the air to the outside, ensuring that the shell 1 is dry and preventing water vapor from accumulating in the shell 1 and condensing again to come into contact with the granular products, thus avoiding the problem of poor drying effect.
