Refer to Fig. 1 and Fig. 2, Fig. 1 and the exemplary dimensional structure diagrams for showing transmission mechanism 100 of Fig. 2.It is described Transmission mechanism 100 includes motor 10, driving wheel 20, follow-up pulley 30, conveyer belt 40 and fixed rotating shaft 50, and the driving wheel 20 is solid Due to the rotating shaft of the motor 10, the driving wheel 20 and the follow-up pulley 30 are connected by the conveyer belt 40, described solid Determine rotating shaft 50 and pass through the follow-up pulley 30, the follow-up pulley 30 can drive the fixed rotating shaft 50 to rotate.

The motor 10 drives driving wheel 20 to rotate, and drives the follow-up pulley 30 to rotate by the conveyer belt 40, enters And drive fixed rotating shaft 50 to rotate together, because the one end of fixed rotating shaft 50 is fixedly connected with switching mechanism, thus, work as fixed rotating shaft During 50 rotation, switching mechanism can be driven to rotate together, realize turn over function.

Please continue to refer to Fig. 3, the structural representation for showing follow-up pulley 30 exemplary Fig. 3, the follow-up pulley 30 Including interior axle portion 31 and outer portion 33, the outer portion 33 is circumferentially stretched out by the interior axle portion 31 to be formed, the interior axle Portion 31 is a solid steel ring, and it is provided centrally with axis hole 311, and the fixed rotating shaft 50 passes through the axis hole 311, so as to by described in Follow-up pulley 30 is fixed on the fixed rotating shaft 50, and some through holes 313, the driven cunning are additionally provided with the interior axle portion 31 Wheel 30 can be realized by the through hole 313 with the fixed rotating shaft 50 engages positioning, for example, in the present embodiment, the through hole 313 Three are arranged to, three fix bars are stretched into the through hole 313 and are fixed on through the through hole 313 on fixed rotating shaft 50, i.e., The fixation that follow-up pulley 30 is relatively fixed rotating shaft 50 can be achieved.

The inwall of axis hole 311 caves inward to form a fixing groove 315, is correspondingly arranged in the fixed rotating shaft 50 fluted Portion 531, when follow-up pulley 30 is sheathed on the fixed rotating shaft 50, the fixing groove 315 is relative with the concave part 531 to be set Put, now, follow-up pulley 30 and fixed rotating shaft 50 can be realized by fixation on axis by a fix bar.

Pass through the setting of fixing groove 315 and concave part 531, through hole 313 so that the band that the follow-up pulley 30 can be calm Move the fixed rotating shaft 50 to rotate, so as to drive the rotation of switching mechanism, complete the turnover panel operation of panel turnover machine.

The outer portion 33 is an annular groove, its friction belt for including the cell wall of groove both sides and being arranged at bottom portion of groove 331, the friction belt 331 is set in intensive waveform, and its height is slightly below the height of the cell wall, the part of transmission belt 40 It is placed in the annular groove, when motor 10 drives driving wheel 20 to rotate, driving wheel 10 drives transmission belt 40 to be driven, conveyer belt 40 rotate when, follow-up pulley 30 is moved by friction belt 331 and rotated, the setting of the friction belt 331, can increase transmission belt 40 with The frictional force of follow-up pulley 30, the bottom portion of groove compared to general follow-up pulley 30 is smooth structure, can further reduce motor Driving power.

Please continue to refer to Fig. 4, the structural representation for showing fixed rotating shaft 50 exemplary Fig. 4.The fixed rotating shaft 50 Including fixed part 51, the first axle part 53 and the second axle part 55, the fixed part 51 be with certain thickness circular plate-like shape structure, The first axle part 53 is stretched out by the fixed part 51 to be formed, and the second axle part 55 is by the first axle part 53 away from institute State the one end of fixed part 51 to stretch out to be formed, the center of the fixed part 51, the axis of the first axle part 53 and described second The axis of axle portion 55 is on same straight line.

Specifically, some fixing holes are provided with the fixed part 51, for the fixed rotating shaft 50 to be fixed on into turnover panel In mechanism, the first axle part 53 is provided with concave part 531, and the length of the concave part 531 is more than the length of the fixing groove 315 Spend and less than twice of the length of fixing groove 315, it is simultaneously solid to cause fix bar not skidded off out of described concave part 531 The assembly or disassembly of fixed pole is not difficult.

Further, the through hole 313 is corresponded on the fixed part 51 and is provided with some blind holes, is gone back in the blind hole further Internal thread can be set, and fix bar is connected in blind hole through through hole rear thread.

The first axle part 53 and the second axle part 55 are optical axis portion, and the radius of the second axle part 55 is less than institute State the radius of the first axle part 53.

The radius of the first axle part 53 is equal to or slightly less than the radius of the axis hole 311, such to set so that described The assembling of follow-up pulley 30 need not overcome great frictional resistance, more just can easily complete the follow-up pulley 30 and described The assembling of fixed rotating shaft 50, simultaneously because the setting of the setting of fixing groove 315 and concave part 531, through hole 313 and blind hole so that Calm drive is realized between fixed rotating shaft 50 and follow-up pulley 30.

Compared with prior art, the transmission mechanism 100 reduces the driving work(of motor 10 by using belt mechanism Rate, while by the setting of fixing groove 315 and concave part 531, the assembling that can solve follow-up pulley 30 and fixed rotating shaft 50 is stranded Difficult problem, while drive rotary action of the follow-up pulley 30 to fixed rotating shaft 50 can also be realized by a fix bar, further, The setting of through hole 313 and blind hole, strengthen the drive rotary action of follow-up pulley 30 and fixed rotating shaft 50 so that the band of transmission belt 40 Drive fixed rotating shaft 50 to rotate while dynamic follow-up pulley 30, and then drive switching mechanism to rotate.

Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, Every any modification made within design of the present utility model, equivalent substitution and improvement etc. should be included in the utility model Scope of patent protection in.
