[0003] After searching, the existing patent (Announcement No.: CN217179125U) discloses a drying device for nylon cable tie extrusion granulation. During use, after the material falls from the feed hopper, the arc-shaped buffer plate and the guide plate can first buffer the material feed, preventing the material from directly falling onto the weighing net, thereby increasing the service life of the weighing net; when the material on the weighing net reaches the preset value of the pressure sensor, the whistle is immediately activated and sounds a whistle to remind the staff to stop feeding. At the same time, the material leveling component and the drying component are immediately activated. The material leveling component can evenly spread the material on the weighing net to prevent accumulation and uneven drying. However, in the process of realizing the utility model, the inventor found that the prior art has the following problems: During the drying process, the above-mentioned drying device simply uses hot air drying to perform the drying action, which has the disadvantage of low drying efficiency and is difficult to meet the demand for rapid drying.

[0023] Reference Figures 1 to 4 The utility model provides a drying device for extruding and granulating nylon cable ties, comprising a mounting frame 1, a controller 24 being fixedly mounted on the right side of the mounting frame 1, and the controller 24 being electrically connected to an external power supply through a wire.

[0024] Two connecting shafts 2 are symmetrically arranged on the inner wall of the mounting frame 1, and a base frame 3 is fixedly installed on one end close to the two connecting shafts 2.

[0026] When drying the plastic raw material pellets, the plastic pellets are added to the drying interlayer 8 between the drying outer cylinder 6 and the drying inner cylinder 7, and the heater 14 is started. The heater 14 blows a hot air flow into the inner side of the drying inner cylinder 7, and the hot air flow then flows out from the ventilation holes 9 and contacts the surface of the plastic pellets, thereby achieving the effect of drying the plastic pellets. Since the plastic pellets are distributed in a thin layer state inside the drying interlayer 8, they are in close contact with the air flow, which can improve the drying effect during drying.

Based on the engagement of the spur rack 23 with the toothed disc 21, the connecting shaft 2 can be driven to deflect, so that the upper opening of the drying interlayer 8 is directed toward the material trough 19, thereby achieving the purpose of quickly discharging the dried raw materials, thereby further shortening the drying process time and improving the drying efficiency.

[0037] A limiting slide bar 15 is fixedly mounted on the surface of the lifting plate 13 , and the limiting slide bar 15 is slidably connected to the top frame 11 .

[0038] It is worth noting that when controlling the hydraulic rod 12 to contract and drive the lifting plate 13 to move upward to avoid the flipping path of the drying outer cylinder 6, by setting the limiting slide bar 15, the stability of the lifting plate 13 during movement can be improved, and the purpose of anti-twisting protection of the telescopic end of the hydraulic rod 12 can be achieved.
