The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As Fig. 1 and shown in Figure 5, in embodiment 1, the utility model is used for the bottle pushing mechanism of tunnel sterilizing and drying machine, comprises the more than one barb 5 that pushes away bottle piece 2 and cooperate with twine on the transmission guipure 1, barb 5 is connected in and pushes away on bottle piece 2, pushes away bottle piece 2 and moves along with transmitting guipure 1 by barb 5.In the present embodiment, barb 5 is to captive joint with pushing away bottle piece 2.When transmitting guipure 1 and travelling forward, the twine that transmits on the guipure 1 promotes barb 5, drives to push away bottle piece 2 and promote medicine bottles 3 and travel forward again.
Since barb 5 with push away between bottle piece 2 to captiveing joint, when pushing away bottle piece 2 and meet with obstruction, barb 5 will be transmitted guipure 1 and withstand, and will damage the twine of transmission guipure 1 when resistance is excessive.Therefore, the utility model further provides the technical scheme of embodiment 2.
Referring to Fig. 2, Fig. 3 and Fig. 4, in embodiment 2, the stage casing of barb 5 is articulated in and pushes away on bottle piece 2, and barb 5 can rotate around hinge-point.The working end of barb 5 cooperates with twine, and non-operative end links to each other with extension spring 6 by bolt, and the other end of extension spring 6 is fixed in and pushes away on bottle piece 2.Extension spring 6 by nut pin 7 and set screw 8 with push away bottle piece 2 and link to each other, nut pin 7 one sides have tapped bore 71, an end of set screw 8 is fixed in and pushes away on bottle piece 2, the other end of set screw 8 is sheathed in the tapped bore 71.Set screw 8 can be according to the position of the tightness setting nut pin 7 of extension spring 6, thereby regulates the pulling force of extension spring 6.An end that cooperates with twine on the barb 5 is del, and handling like this is to push away the reaction thrust that can be subjected to rebound 4 when bottle piece 2 arrives rebounds 4 for convenience, and clickwise is regained automatically, makes to push away bottle piece 2 and can arrive smoothly on the rebound 4.Push away the rounding all around of bottle piece 2, in case thrust bottle piece 2 is transmitting the baffle plate that is suspended to the side on the guipure 1.
Referring to Fig. 6, the direction of arrow transmits the service direction of guipure 1, when producing end, the more than one bottle piece 2 that pushes away of the present utility model is relied on the back that last arranges medicine bottle 3, and place it on the transmission guipure 1 of tunnel sterilizing and drying machine.The barb 5 that pushes away bottle piece 2 is inserted in the middle of the twine that transmits guipure 1, relies on the thrust that transmits guipure 1 previous motion, and pulling is inserted in the barb 5 that transmits in guipure 1 twine and promotes bottle piece 2, reaches with the lighter purpose that bottle piece 2 promotes last row's medicine bottle 3 that pushes away.Referring to Fig. 7, push away the reaction thrust that can be subjected to rebound 4 when bottle piece 2 arrives rebound 4, clickwise is regained automatically.Referring to Fig. 8, when rebound 4 or medicine bottle 3 when being subjected to strong resistance because barb 5 is to be inserted in the middle of the twine that transmits guipure 1, transmits guipure 1 and travelled forward by the motor pulling force, if hold-off pressure does not push away bottle piece 2 and will crush anterior medicine bottle 3 or element part is hung wound.Adopt extension spring 6 that pulling force is provided in the upper end of barb 5, when jam occurring, when transmitting thrust that guipure 1 provides greater than the pulling force of extension spring 6 on the barb 5, extension spring 6 elongations, barb 5 left-hand revolutions are unlikely to like this to hang and hinder guipure or damage medicine bottle 3 by pressure.
