Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, ordinary skill staff are obtained all without making creative work
Other embodiment shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the present invention provides a kind of technical solution：
Former and later two upward left support plates 1 are equipped on the left of the upper end of bottom plate, and the rear end on the right side of the upper end of bottom plate is equipped with
Two upward right support plates 2 are rotatably connected to left rotary shaft 3 between former and later two left support plates 1, rolling are socketed in left rotary shaft 3
Wheel 4, idler wheel 4 is fixedly connected with left rotary shaft 3.It is rotatably connected to right spindle 5 between two right support plates 2.It is socketed on right spindle 5
Roller 6, the two is fixedly connected.And the outer diameter of roller 6 is more than the outer diameter of idler wheel 4, when such spray painting cloth is drawn, left rotary shaft 3 rotates
Angular speed be more than the angular speed of roller 6, air brushing yardage roll 7 is socketed on roller 6, the linear velocity of left rotary shaft 3 is equal to air brushing yardage roll 7
Linear velocity, the linear velocity of air brushing yardage roll 7 is the movement speed of spray painting cloth.The both sides of right spindle 5 are connected through a screw thread block 61,
Block 61 resists air brushing yardage roll 7 and will not skid off.It is socketed with slide cartridge 8 in left support plate 1, can move up and down, the lower end of slide cartridge 8 is equipped with
The lower end of downward flaps 9, flaps 9 is against on idler wheel 4, and the free end of air brushing yardage roll 7 is between flaps 9 and idler wheel 4
It passes through, the end face that flaps 9 is contacted with spray painting cloth is equipped with non-slip rubber block, increases resistance, ensures that unreeling for spray painting cloth is steady.It is left
Shaft 3 passes through left support plate 1 to side and is fixedly connected with active synchronization belt wheel 10.And right spindle 5 passes through right support to homonymy
Plate 2 is connected with driven synchronous pulley 11, and driven synchronous pulley 11 is rotatablely connected between right spindle 5.Active synchronization belt wheel 10
It is connected by synchronous belt 12 between driven synchronous pulley 11.The inner hollow of driven synchronous pulley 11, driven synchronous pulley 11
Internal chamber wall on be hingedly connected with brake bar 13 at equal intervals, pass through torsion between brake bar 13 and the internal chamber wall of driven synchronous pulley 11
Spring 14 connects.The free end of brake bar 13 negative direction that shaft 5 rotates to the right tilts, and the free end of brake bar 13 is against right-hand rotation
On axis 5, the circumferential direction of right spindle 5 offers card slot 15 corresponding with brake bar 13 at equal intervals, and card slot 15 is in 5 rotation direction of right spindle
The inner cavity surface of side is radially to outer rim arc transition.
The movement speed of spray painting cloth is a, and the linear velocity of idler wheel 4, the linear velocity of air brushing yardage roll 7 are a.Air brushing yardage roll 7
Outer diameter is more than idler wheel 4, so the angular speed of idler wheel 4 is more than the angular speed of air brushing yardage roll 7.
Since idler wheel 4 and 10 coaxial synchronous of active synchronization belt wheel move, the angular speed of the two is identical.Active synchronization belt wheel 10
Big with the outer diameter of driven synchronous pulley 11 etc., active synchronization belt wheel 10 and the linear velocity and angular speed of driven synchronous pulley 11 are homogeneous
Together.So the angular speed of driven synchronous pulley 11 is more than the angular speed of air brushing yardage roll 7.So the angular speed of driven synchronous pulley 11
More than the angular speed of right spindle 5, i.e., the ratio right spindle 5 of driven 11 turns of synchronous pulley is fast.5 turns of driven synchronous pulley 11 and right spindle
To identical, driven synchronous pulley 11 drives rotating bar 13 to be skidded off from card slot 15.Upper end is hingedly connected on bottom plate to be tilted to the right
Bull stick 16, the upper end of bull stick 16 is located at the right side of air brushing yardage roll 7, is connected by spring 17 between bull stick 16 and bottom plate, spring
17 are located at the left side of bull stick 16, and the free end of bull stick 16 is equipped with metering roll 18, and metering roll 18 is against on air brushing yardage roll 7, is grown
Degree metering, spring 17 guarantee jam-packed.
When use：
Block 61 is screwed off, air brushing yardage roll 7 is sleeved on roller 6, screws on block 61, air brushing yardage roll 7 is carried out and fixes, spray painting cloth
Through being passed through between idler wheel 4 and flaps 9, flaps 9 is under the gravity of slide cartridge 8, jam-packed spray painting cloth, provides resistance, ensures air brushing
Cloth unreels more stable.
Pull spray painting cloth, spray painting cloth that idler wheel 4 and air brushing yardage roll 7 is driven to rotate, left rotary shaft 3 and right spindle 5 rotate, left rotary shaft
3 drive active synchronization belt wheel 10 to rotate, and right spindle 5 drives driven synchronous pulley 11 to rotate, and the angular speed of left rotary shaft 3 is more than roller
6, that is, it is more than right spindle 5, active synchronization belt wheel 10 is identical with the angular speed of driven synchronous pulley 11, is also equal to left rotary shaft 3
Angular speed, the angular speed of driven synchronous pulley 11 in this way is more than the angular speed of right spindle 5, and therefore, brake bar 13 is relative to the right side
Shaft 5 rotates, and skids off card slot 15, and metering roll 18 carries out length metering, after reaching length, stops traction.In the effect of flaps 9
Under, idler wheel 4 stops, to make active synchronization belt wheel 10 and driven synchronous pulley 11 stop.
Because inertia is rotated further, card slot 15 can resist brake bar 13, driven synchronous pulley 11 for air brushing yardage roll 7 and roller 6
Right spindle 5 is braked by rotating bar 13.There is the frictional force between flaps 9 and spray painting cloth to stop for brake force, thus into
Row braking, prevents air brushing yardage roll 7 to be rotated further, and the spray painting cloth between such idler wheel 4 and air brushing yardage roll 7 would not relax, and ensures
Unreel quality.
