Specific embodiment

The utility model is described in further detail combined with specific embodiments below.

Embodiment:

As shown in Figure 1 to Figure 3, a kind of transmission wire body of the utility model, the revolution including two with semi-circular track 11 Component 1 and the multipair transmission component 2 with rectilinear orbit 21, two semi-circular tracks 11 and multiple rectilinear orbits 21 connect from beginning to end If at the cyclic track for supplying 3 loopy moving of dryed product carrier；The inside of cyclic track is equipped with central supporting platform 4, central supporting Platform 4 is used to fix working cell.Two gyro black assemblies 1 and cyclic track, work arbitrarily can be built to transmission component 2 Make unit on central supporting platform 4, when product carrier 3 carries the specific position that product is moved on rectilinear orbit 21, Working cell can carry out corresponding operation to product.Working cell can be feeding unit material, processing unit and blanking unit etc..Cause It is all modular component for gyro black assembly 1, transmission component 2, product carrier 3 and central supporting platform 4, so transmission wire body Scale can arbitrarily be increased or decreased according to process complexity, there is preferable applicability.

As shown in Figure 1, the outside of cyclic track is equipped with lateral support platform 5, lateral support platform 5 is used to fix job note Member.When working cell is than comparatively dense, certain working cells be can be set in lateral support platform 5, avoid operated adjacent Unit is too close and generation movement is interfered.

As shown in Fig. 2, the outside of rectilinear orbit 21 is equipped with friction wheel assembly 26 corresponding with working cell position, product is carried The bottom of tool 3 is equipped with the elastic piece 32 being in contact with friction wheel assembly 16, and the front and rear of elastic piece 32 respectively has a transition Slope 321.Product carrier 3 blocks during mobile on cyclic track in order to prevent, and product carrier 3 can float there are certain Space, but this float to product orientation when processing is unfavorable.Friction wheel assembly 16 with elastic piece 32 is flexible contacts, rub Fixed function can be played to product carrier 3 to improve product orientation precision by wiping wheel assembly 16.Transitional slope 321 is used to slow down to rub Wipe collision when wheel assembly 16 is just contacted with elastic piece 32.

As shown in Figure 1, gyro black assembly 1 includes frictional disk 12, the axis of frictional disk 12 is overlapped with the axis of semi-circular track 11； When product carrier 3 reaches in semi-circular track 11, frictional disk 12 is contacted with the bottom of product carrier 3.When product carrier 3 reaches directly Semi-circular track 11 will be entered when 21 end of trajectory, frictional disk 12 is sent product carrier 3 to next by lasting rotation Rectilinear orbit 21, such product carrier 3 can recycle in transmission wire body.

As shown in Figure 1, gyro black assembly 1 further includes being parallel to semi-circular track 11 to import and export tangential friction belt 13, friction The upper surface of belt 13 and the upper surface of frictional disk 12 are contour.It is limited to the structure of frictional disk 12, product carrier 3 is from rectilinear orbit 21 Linking movement is completed to friction belt 13 is also needed between semi-circular track 11.

As shown in Figure 1, if 3 front and back of dryed product carrier is hingedly an entirety flexible.The product carrier to string 3 It needs in a part of driven situation, other parts can link, and facilitate product orientation in this way.

As shown in Figure 1 to Figure 3, the side of rectilinear orbit 21 is articulated with worm screw 22, and worm screw 22 is equipped with helicla flute and (does not mark Note), product carrier 3 is equipped with the idler wheel 31 of cooperation helicla flute.The effect of product carrier 3 on rectilinear orbit 21 in worm screw 22 Lower advance, idler wheel 31 can reduce the frictional force that this driving generates.

As shown in Figure 1, Figure 4 and Figure 5, worm screw 22 is driven by the worm drive mechanism that one includes motor 22.When this electricity Machine 22 can pause when being servo motor, and product carrier 3 is allowed to stop, and then leave the time of operation unit operation.

As shown in Figure 1, Figure 4 and Figure 5, motor 22 controls a driving gear 23, and worm screw 22 connects one and driving gear 24 The driven gear 25 of engagement, driving gear 24 include main toothed region 241 and convex curvilinear 242, and driven gear 25 includes cooperation master The slave toothed region 251 of toothed region 241 and the concave curvilinear portion 252 of cooperation convex curvilinear 242, the outlet side of convex curvilinear 242 is set There is convex portion 243, the side of driven gear 251 is equipped with the swing rod 253 of cooperation convex portion 243.Uniform rotation can be used in motor 22 herein Ordinary motor.When main toothed region 241 and when engage from toothed region 251, the rotation of driving gear 23 and driven gear 24 Rotation be synchronous, and when wait convex curvilinears 242 and concave curvilinear portion 252 to cooperate, driving gear 23 is dynamic and driven gear 24 is motionless, and such worm screw 22 can also be parked in a fixed position to allow product carrier 3 to stop.Until convex portion 243 encounters pendulum Bar 253, then the rhythm for allowing driven gear 25 to keep up with driving gear 24.The advantages of this arrangement are as follows first convex curvilinear 242 with The angle precision of worm screw 22 is very high when concave curvilinear portion 252 cooperates, this can ensure that the position precision of product；Second this mistake Journey only needs to select ordinary motor to complete, and cost of parts is low.

As shown in Fig. 2, the bottom of product carrier 3 is articulated with multipair pulley 33 vertically, each pair of pulley 33 presss from both sides cyclic track In centre.Pulley 33 and cyclic track carry out the relative movement of low friction resistance.

As shown in Fig. 2, the centre of pulley 33 has V-groove circle 331, rectilinear orbit 21 has the convex of cooperation V-groove circle 331 Ridge 221.The cooperation of V-groove circle 331 and convex ridge 221 is used to reduce the height error of product carrier 3, improves the height essence of product Degree.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical Novel protection scope.
