Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
It is a kind of overall structure diagram of the circular line of auto-tensioning of the invention, including ring shown in referring to Fig.1
Shape rack 110 is provided with ring-shaped guide rail 120 and slide block assembly 130 on the annular framework 110, and product to be transported is set to cunning
On block assembly 130, slide block assembly 130 is moved along ring-shaped guide rail 120, and the ring-shaped guide rail 120 is set to the annular framework 110
Outer rim, therefore the power source by slide block assembly 130 is facilitated to be set to the inside of annular framework 110, annular described in the present embodiment
The corner of 110 inside of rack is respectively equipped with the mounting plate 111 of installation driving device 140 and slave unit 150, synchronous belt 160
Around the driving device 140 and slave unit 150, mounting plate 111 is arranged according to actual needs, without covering entire annular machine
On the one hand frame 110 saves material, on the other hand, since each side of annular framework 110 is likely to be in different processing spaces,
Therefore only at turning, setting mounting plate 111 facilitates and is isolated each while with other, and the annular framework 110 in the present embodiment is four sides
Shape structure, therefore, driving device 140 and slave unit 150 are set to quadrangle, and driving device 140 is provided with one, slave unit
There are three 150 settings, likewise, can increase the quantity of driving device 140 if necessary to bigger power.The sliding block group
Part 130 is arranged on the ring-shaped guide rail 120, prevents from falling off from guide rail during the motion, and synchronous belt 160, which is located at, at this time slides
130 inside of block assembly, although synchronous belt 160, which forms closed loop around driving device 140 and slave unit 150, tightens form, by
It is longer in the straight line edge lengths of circular line and itself is elastomer, therefore certain bullet is had in the position of Linear transmission
Property deformation, therefore in the present embodiment, 130 side of slide block assembly is fixed by the first tension assembly 170 and the synchronous belt 160
Connection, the distance between the slide block assembly 130 and synchronous belt 160 are less than the size of first tension assembly 170, work as sliding block
When component 130 is in linear transmission position, since position of the slide block assembly 130 in guide rail vertical direction is fixed, first
Tension assembly 170 compresses synchronous belt 160 inwardly, ensure that the tensioning of synchronous belt 160.
It is 170 structural schematic diagram of the first tension assembly of the invention, due to the first tension assembly 170 referring to shown in Fig. 2
Size is greater than the distance between slide block assembly 130 and synchronous belt 160, when slide block assembly 130 is in corner location, synchronous belt
160 are bonded with synchronous pulley 141, and the first tension assembly 170 can not inwardly release synchronous belt 160, to enable slide block assembly 130
Enough pass through turn position, in the present embodiment, first tension assembly 170 includes the connection connecting with slide block assembly 130
U-shaped fixed plate 171 that plate 174, bottom surface and synchronous belt 160 connect, the elastic component 172 for being connected to the extension of U fixed plate inward at both ends
And it is held on the L-type link block 173 between two elastic components 172 on one side, it is solid at the top of the L-type link block 173 and connecting plate 174
Fixed connection, due to the setting of L-type link block 173, there are certain gap between U-shaped fixed plate 171 and slide block assembly 130, when
When slide block assembly 130 moves to the position of synchronous pulley 141, due to the blocking of synchronous pulley 141, elastic component 172 is to sliding block group
The direction of part 130 generates deformation, and U-shaped fixed plate 171 is driven to generate displacement to the direction of slide block assembly 130, so that the first tensioning
The size of component 170 reduces, and slide block assembly 130 is facilitated to pass through turn position.
It is the structural schematic diagram of driving device 140 and slave unit 150 of the present invention, the drive referring to shown in Fig. 3 and Fig. 4
Dynamic device 140 and slave unit 150 include axle sleeve 143, shaft 142 and synchronous pulley 141, the synchronous pulley 141 and institute
It states shaft 142 to be fixedly connected, the driving device 140 further includes driving motor 144, the rotation of 144 drive shaft 142 of driving motor
Turn, drives synchronous pulley 141 to rotate, to drive synchronous belt 160, the movement of synchronous belt 160 is further driven to slave unit 150
Synchronous pulley 141 rotate, and synchronous belt 160 draws slide block assembly 130 and along circular orbit does synchronous intermittent movement, corresponding
, driving device 140 further includes speed reducer 145, the deceleration of driving wheel is directly used in, between the synchronization to realize slide block assembly 130
It has a rest movement.In the present embodiment, the shaft 142 is set in the axle sleeve 143, and shaft 142 is installed on annular machine by axle sleeve 143
On frame 110, since synchronous belt 160 inevitably relaxes after long-term operating, for for further adjusting synchronous belt 160
Tightly, in the present embodiment, the axle sleeve 143 is connect by the second tension assembly 180 with the mounting plate 111, passes through the second tensioning
Component 180 adjusts the position of axle sleeve 143, is on the whole tensioned synchronous belt 160.Second tension assembly 180 includes limit
Plate 181, the axle sleeve 143 are set up in the mounting hole of the mounting plate 111 by limit plate 181, due to limit plate 181 and peace
Loading board 111 is fixed, therefore can guarantee the connection of axle sleeve 143 Yu mounting plate 111 by the connection of axle sleeve 143 and limit plate 181,
The limit plate 181 is connect by the first waist-shaped hole 182 with axle sleeve 143, enables direction and limit of the axle sleeve 143 along waist-shaped hole
Position plate 181 generates relative movement, and 142 two sides of shaft are provided with the tensioning notch 183 in the same direction with the first waist-shaped hole 182, lean on
Dive key 184 on the tensioning notch 183 and the mounting plate 111 of nearly 160 side of synchronous belt cooperates, and makes shaft 142
It can be moved along the direction of dive key 184, the tensioning notch 183 far from 160 side of synchronous belt is fixed with adjusting rod
185, adjusting rod 185 is stuck in tensioning notch 183, so that the direction of adjusting rod 185 is consistent with the moving direction of shaft 142, when
When applying 185 end of adjusting rod along the thrust of 185 length direction of adjusting rod, it can guarantee that thrust acts on shaft 142 completely
On, to push shaft 142 mobile, adjusting rod 185, the peace in 185 end of adjusting rod are pushed in the present embodiment
Adjustable plate 186 is fixed in loading board 111, tensioning screw 187 passes through the adjustable plate 186 and abuts adjusting rod 185, screws when inwardly
When tensioning screw 187, adjusting rod 185 is tensioned 187 pushing tow of screw, pushes shaft 142 to moving on the outside of synchronous belt 160, from whole
Synchronous belt 160 is tensioned on body.Further, since 185 length of adjusting rod is longer, to guarantee the adjusting rod in loading process
185 will not shift, and be equipped with regulating tank 112 in the mounting plate 111, the adjusting rod 185 is arranged in the regulating tank 112
It is interior.Further, since the driving motor 144 is connected to 142 lower section of shaft, to guarantee that shaft 142 is being pushed to move
Driving motor 144 can be driven mobile when dynamic simultaneously, the driving motor 144 passes through same with first waist-shaped hole 182
To the second waist-shaped hole 188 connect with the mounting plate 111, driving motor 144 can be moved along the direction of the second waist-shaped hole 188
It is dynamic.
