When blowing the plastic strips dry, the staff needs to use a drying device.

[0003] However, there are some problems with the prior art: although the existing drying device can blow and dry the strands through a blower, in actual use, the existing drying device usually blows the warm air from the top of the strand downwards through the warm air delivered to the inside of the air distribution box by the heater during the strand conveying process. This method can only dry the upper part of the strand, while the bottom of the strand is difficult to be blown by the warm air, thereby reducing the overall drying effect. Therefore, we propose a drying device for strand granulation. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, a drying device for strand granulation provided by an embodiment of the utility model comprises a base 1, a heater 2 is fixedly installed on the top of the base 1, a vertical pipe 3 is fixedly connected to the air outlet end of the heater 2, the other end of the vertical pipe 3 is fixedly connected to an air distribution box 4, a water trough 5 located below the air distribution box 4 is fixedly installed on the vertical pipe 3, a circular pipe 6 is rotatably connected between the inner walls on both sides of the water trough 5, a curved pipe 7 is rotatably connected to the rear end of the circular pipe 6, the other end of the curved pipe 7 is fixedly connected to the vertical pipe 3, a nozzle 8 is fixedly connected to the outer surface of the circular pipe 6, the circular pipe 6 and the water trough 5 are connected by a driving mechanism, and a vibration mechanism is arranged at the bottom of the air distribution box 4.

[0027] Furthermore, the driving mechanism includes a driving motor 9, which is fixedly mounted on the right end of the water tank 5. The output shaft of the driving motor 9 is fixedly sleeved with a rotating shaft 10, and the circular tube 6 is connected to the rotating shaft 10 through a transmission assembly.

[0028] Furthermore, the transmission assembly includes a worm 11 and a gear 12 . The worm 11 is fixedly sleeved on the outer surface of the rotating shaft 10 , and the gear 12 is fixedly sleeved on the outer surface of the circular tube 6 . The gear 12 and the worm 11 are meshedly connected.

[0029] By starting the driving motor 9, the rotating shaft 10 can drive the worm 11 to rotate, so that the gear 12 can drive the circular tube 6 to rotate, and then the circular tube 6 can drive the nozzle 8 to rotate, so that the bottom of the pull strip can be blown and dried. Moreover, since the circular tube 6 drives the nozzle 8 to rotate and blows the pull strip to dry at the same time, the time that the pull strip is blown by warm air during the transmission process can be increased, thereby improving the drying effect.

[0030] Furthermore, guide rollers 13 are rotatably connected between the inner walls on both sides of the water tank 5. There are two guide rollers 13, and the two guide rollers 13 are symmetrically arranged.

[0031] The design of the guide roller 13 can make the pull rods more smooth during the transmission process, and can prevent adjacent pull rods from sticking to each other and entanglement.

[0032] Furthermore, the bottom of the inner wall of the water tank 5 is inclined, and a valve 14 is fixedly installed at the bottom of the water tank 5 .

[0033] The water dripping from the pull rod into the water tank 5 will flow along the inner wall of the water tank 5 to the vicinity of the top of the valve 14, and the staff can open the valve 14 to discharge the water.

[0034] Furthermore, the vibration mechanism includes a guide rod 15, which is movably inserted in the bottom of the air distribution box 4, and the bottom of the guide rod 15 is fixedly connected to a bottom plate 16, and the bottom of the bottom plate 16 is fixedly installed with a gasket 17. The bottom of the air distribution box 4 is fixedly installed with a brake motor 18, and the output shaft of the brake motor 18 is fixedly sleeved with a round shaft 19, and the other end of the round shaft 19 is fixedly connected with a cam 20, and the cam 20 is fitted on the top of the bottom plate 16.

[0035] Furthermore, a spring 21 is movably sleeved on the outer surface of the guide rod 15 , and two ends of the spring 21 are fixedly connected to the air distribution box 4 and the bottom plate 16 respectively.

[0036] By setting the spring 21 to a stretched state, the bottom plate 16 will tend to move upward due to the elastic recovery effect of the spring 21. By starting the brake motor 18, the round shaft 19 can drive the cam 20 to rotate, so that in cooperation with the spring 21, the bottom plate 16 can drive the gasket 17 to move up and down, so that the gasket 17 can repeatedly beat the pull rod, thereby shaking off the water droplets on the pull rod, making the pull rod easier to be blown dry by warm air.

[0037] Furthermore, a guard plate 22 located outside the gear 12 is fixedly mounted on the front of the water tank 5 , and the length of the guard plate 22 is greater than the length of the rotating shaft 10 .

[0038] Furthermore, the nozzle 8 has a cylindrical appearance and is evenly distributed on the outer surface of the circular tube 6 .

[0039] Furthermore, the gasket 17 has a square appearance, and the length of the gasket 17 is the same as the length of the bottom plate 16 .

[0040] The gasket 17 can be made of rubber. Since rubber is soft, it can avoid abrasion of the pull rod when the pull rod is tapped.

[0041] Working principle: After being water-cooled, the strands are conveyed from the surface of the guide roller 13 to the pelletizer. The staff can start the heater 2 so that the warm air can be conveyed through the vertical pipe 3 to the inside of the air distribution box 4 and blown downward, thereby blowing and drying the top of the strands. At the same time, the warm air will be conveyed from the vertical pipe 3 through the curved pipe 7 to the inside of the circular tube 6, and finally blown out from the nozzle 8, thereby blowing and drying the bottom of the strands. The staff can start the drive motor 9 so that the rotating shaft 10 drives the worm 11 to rotate, thereby allowing the gear 12 to drive the circular tube 6 and the nozzle 8 to rotate, thereby evenly blowing and drying the bottom of the strands.

[0042] At the same time, the staff can start the brake motor 18. Due to the operation of the brake motor 18, the round shaft 19 can drive the cam 20 to rotate, so that in cooperation with the spring 21, the bottom plate 16 can drive the gasket 17 to reciprocate up and down, and then the gasket 17 can repeatedly beat the pull strip, so as to shake off the water droplets adhering to the pull strip, and make the pull strip easier to be blown dry by warm air.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
