Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe.

The drying device of this plastic strip of the present utility model as shown in Fig. 1 to 7, by blower fan 10, the and of blower mechanism 20 Load carrier 30 is constituted.The blower fan 10 is connected to the blower mechanism 20, and the blower mechanism 20 is located at the load carrier 30 Top.Dry gas is blown into load carrier 30 by blower mechanism 20, and high temperature plastics bar 40 is passed through from the load carrier 30, reached To the purpose for quickly going water to dry.The load carrier 30 includes casing 31, the first support roller 32, the second support roller 33, centre Roller group 34 and commutation support roller 35.Plastic strip 40 enters dry place through the first support roller 32, is left through the second support roller 33 Dry place.The support roller 33 of first support roller 32 and second is rotatably mounted in the casing 31, the centre Roller group 34 is located between first support roller and the second support roller.Specifically, casing 31 is substantially spelled by multiple plate objects 36 Conjunction is formed, and each support roller is fixed between plate object 36.

In the utility model, middle roller group 34 is made up of upper backup roll 37 and lower backing roll 38, the upper backup roll 37 It is rotatably mounted in the casing 31 with lower backing roll 38.Between the first support roller 32 and the second support roller 33 Middle roller group 34 separates adjacent plastic strip 40, and the top of partly plastic bar 40 from upper backup roll 37 is passed through, another part modeling Material strip 40 is passed through from the lower section of lower backing roll 38.This transmission structure is conducive to improving the spacing between plastic strip 40, improves modeling The surface area that material strip 40 is contacted with the external world.The excircle of the excircle of upper backup roll and lower backing roll 38 is tangent, upper backup roll 37 Equal with the diameter of lower backing roll 38, upper backup roll 37 coordinates with the uniform velocity of lower backing roll 38 to be rotated.Above and below the structure can ensure The shifting speed of plastic strip 40 quite, if upper plastic strip 40 moves fast increase, drives to inevitable uniform velocity lower plastic strip 40 to move.It is described Upper backup roll 37 and/or the support roller 32 of lower backing roll 38 and first and/or the second support roller 33 have a plurality of locating slot 39.It is fixed Position groove is conducive to limiting the position of plastic strip 40, prevents blower mechanism 20 from moving plastic strip 40.First support roller 32, upper branch Support roller 37, the second support roller 33 and lower backing roll 38 surround a parallelogram.First support roller 32 is arrived through upper backup roll 37 The distance of second support roller 33 is equal with the first distance of the support roller 32 through the support roller of lower backing roll 38 to the second 33.

Preferably, reference picture 6,7, the blower mechanism 20 is provided with blowing mouth 21, the blowing mouth 21 has multiple flow deflectors 22.The casing 31 is provided with air outlet 23, and the air outlet 23 has multiple spoilers 24.Flow deflector 22 and spoiler 24 are V Type structure, the channeling direction of the V-structure of flow deflector 22 is identical with wind direction, and wind, to separating, uniformly blows through the rear of flow deflector 22 To plastic strip 40.The channeling direction of the V-structure of spoiler 24 is with wind direction on the contrary, wind is reversely blown to plastics after the spoiler 24 The bottom of bar 40.The structure of flow deflector 22 and spoiler 24 is conducive to moisture content to depart from, and improves drying efficiency.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
