Specific implementation mode

The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to It is lower described：

As shown in Fig. 1 ~ 3, a kind of chip drying system, it includes rack 1, feed device and blow device, the rack 1 Left and right end portions be rotatably installed with active roll tube 2 and driven roller 3 through shaft respectively, pacify between active roll tube 2 and driven roller 3 Equipped with flat rubber belting 4, it is provided with multiple storing units on the top surface of flat rubber belting 4, camshaft 5 is rotatably installed between the rack 1, it is convex Cam 6 is installed, cam 6 is between active roll tube 2 and driven roller 3, and cam 6 is located at the levels of flat rubber belting 4 on wheel shaft 5 Between, handle is installed, worker can be by rotational handle with rotation cam axis 5 on camshaft 5.

As shown in Figure 1 and 2, the feed device includes holder, inclined plate 7 and funnel 8, and holder is fixedly arranged in rack 1 and is located at The right side of driven roller 3, inclined plate 7 are set on holder, and the lower end of inclined plate 7 is being located on flat rubber belting 4 rightmost side storing unit just Top is provided with water accepting layer 9 on the top surface of inclined plate 7, and water accepting layer 9 described in the present embodiment is water suction ointment layer, and absorb water ointment The ointment of layer can quickly absorb moisture, and funnel 8 is located at the top of inclined plate 7, and funnel 8 is fixedly arranged on cradle top.Such as the institutes of Fig. 1 ~ 2 Show, the blow device includes the portal frame 15 being set in rack 1, and the bottom of 15 crossbeam of portal frame is provided with pipeline 10, pipe Be provided on road 10 into heat pipe 11, on the bottom surface of pipeline 10 and along its length on be provided with multiple air nozzles 12.

As shown in Figure 1 and 2, the storing unit includes two coaming plates being set on flat rubber belting 4 13, between two coaming plates 13 There are two filter screen 14,4, two filter screens 14 of the flat rubber belting and two coaming plates 13 to surround the space for accommodating chip for setting.It is described Motor 16 is installed in rack 1, the output shaft of motor 16 is connect with the shaft of active roll tube 2.

The course of work of the utility model is as follows：

The feeding of S1, chip：Chip to be dried is launched into funnel 8, chip is moved down along water accepting layer 9, is being moved Water accepting layer 9 is contacted with chip during dynamic, and the most of moisture that 9 absorbent cores on piece of water accepting layer carries, subsequent chip falls into flat rubber belting 4, in the space that two filter screens 14 and two coaming plates 13 are surrounded, stop to funnel after accumulating certain amount chip in space Chip is launched in 8；

The drying of S2, chip：Start motor 16, motor 16 drives active roll tube 2 to rotate counterclockwise, and active roll tube 2 is through flat Band 4 drives driven roller 3 to rotate, and flat rubber belting 4 drives the chip in space to be moved to drying station, when chip motion to air nozzle 12 Underface when, worker closes motor 16, while into being passed through hot gas in heat pipe 11, and hot gas enters after pipeline 10 from air nozzle 12 It ejects, hot gas is blown into dry the moisture of chip surface in space, and at the same time operation handle is with rotation cam axis 5, rotation Camshaft 5 rotated with moving cam 6, the reciprocal lower surface for tapping 4 upper layer of flat rubber belting of cam 6 so that the chip in space stirs, It, to accelerate to dry the period, improves and dries to increase the contact area of chip and hot gas with hot air impingement again during stirring Efficiency.In addition chip is dried under state of stirring, and moisture will not rest on chip surface and form spray line, is improved The surface quality of chip after drying；

After S3, drying, motor 16 is again started up to convey the finished chip after drying to the left, is taken convenient for worker.Cause This drying system realizes the preliminary most of water removal of chip by step S1, then the hot gas by being passed through in step S2 is to accelerate Chip drying rate, further improves the drying efficiency of chip, greatly shortens the drying period.
