Description
Technical field
The utility model relates to a kind of take-up device, especially relates to a kind of bander secondary take-up device that adopts pneumatic tension.
Background technology
Steel pipe bind is commonly once tension at present, and when the pipe bundle was larger, tightening force was inadequate, makes the pipe bundle loose, and cob webbing causes certain influence to transportation and stock.
Summary of the invention
In order to overcome original disadvantage of only once straining, the purpose of this utility model is to provide a kind of bander secondary take-up device, and being further increases tightening force with the secondary tension.
The technical solution adopted in the utility model is:
the utility model comprises cylinder, ratchet push rod, lower pressure wheel, upper pressure wheel, depression bar, push rod, spring, the first slide block, the second slide block, eccentric cam shaft, clutch shaft bearing, the second bearing, copper sheathing and hand lever, cylinder rod on cylinder is connected with ratchet push rod one end, the ratchet push rod other end is connected with the second coaxial bearing, lower pressure wheel is connected with the second bearing bore is coaxial, the ratchet engagement of the ratchet of lower pressure wheel endoporus and the ratchet push rod other end, clutch shaft bearing is equipped with upper pressure wheel outward, copper sheathing is equipped with respectively at the two ends of eccentric cam shaft, the copper sheathing outer ring is fixed on frame, on eccentric shaft part in the middle of eccentric cam shaft, clutch shaft bearing is housed, eccentric cam shaft rotates around the copper sheathing inner ring, one end of depression bar one end and eccentric cam shaft is rigidly connected, the depression bar other end is connected with push rod one end, push rod other end cover has spring and is connected with the first slide block, the first slide block is connected with the second slide block through hand lever, the steel band of being strained by secondary is pressed between upper pressure wheel and lower pressure wheel.
The beneficial effect that the utlity model has is:
The utility model increases ratchet device on the basis of original hold-down mechanism, ratchet device connects cylinder, utilizes the thrust of cylinder that the steel band of once straining is strained again, can obtain than the large tightening force more than 1 times of tightening force.Control to adjust cylinder intake pressure by gas circuit, maximum can produce the tightening force that surpasses 20000 newton, plays the effect of regulating tightening force.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is initial condition figure of the present utility model.
Fig. 3 is working state figure of the present utility model.
In figure: 1, cylinder, 2, the ratchet push rod, 3, lower pressure wheel, 4, upper pressure wheel, 5, depression bar, 6, push rod, 7, spring, the 8, first slide block, the 9, second slide block, 10, eccentric cam shaft, 11, clutch shaft bearing, the 12, second bearing, 13, copper sheathing, 14, hand lever.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
as shown in Figure 1, the utility model comprises cylinder 1, ratchet push rod 2, lower pressure wheel 3, upper pressure wheel 4, depression bar 5, push rod 6, spring 7, the first slide block 8, the second slide block 9, eccentric cam shaft 10, clutch shaft bearing 11, the second bearing 12, copper sheathing 13 and hand lever 14, cylinder rod on cylinder 1 is connected with ratchet push rod 2 one ends, ratchet push rod 2 other ends are with second bearing 12 is coaxial is connected, lower pressure wheel 4 and the second coaxial connection of bearing 12 endoporus, the ratchet engagement of the ratchet of lower pressure wheel 3 endoporus and ratchet push rod 2 other ends, the outer upper pressure wheel 4 that is equipped with of clutch shaft bearing 11, copper sheathing 13 is equipped with respectively at the two ends of eccentric cam shaft 10, copper sheathing 13 outer rings are fixed on frame, on eccentric shaft part in the middle of eccentric cam shaft 10, clutch shaft bearing 11 is housed, eccentric cam shaft 10 rotates around copper sheathing 13 inner rings, one end of depression bar 5 one ends and eccentric cam shaft 10 is rigidly connected, depression bar 5 other ends are connected with push rod 6 one ends, push rod 6 other end covers have spring 7 and are connected with the first slide block 8, the first slide block 8 is connected with the second slide block 9 through hand lever 14, the steel band of being strained by secondary is pressed between upper pressure wheel 4 and lower pressure wheel 3.
As shown in Figure 2, when hand lever 14 upwards pulled, eccentric cam shaft 10 will be around the rotation of the center-point of copper sheathing 13, and produces gap e, at this moment, can with steel band take the lead send between lower pressure wheel 3 and upper pressure wheel 4.
As shown in Figure 3, after steel band is once strained end, valve control cylinder 1 rollback, will drive ratchet push rod 2 left-hand revolutions this moment, drive simultaneously lower pressure wheel 3 left-hand revolutions, and steel band further moves to left and strains,
If the center of copper sheathing 13 and the center of clutch shaft bearing 11 and the center of lower pressure wheel 3 are coupled together with imaginary straight line, can form triangle, thereby the tightening force of steel band will make the eccentric cam shaft 10 downward component of generation push down steel band this moment, according to tribology principle, friction force is directly proportional to the eccentric cam shaft 10 downward component that produces, therefore friction force will increase, and can not skid when making lower pressure wheel 3 tension steel band.
After tension once, cylinder drives the motion of ratchet pull bar, drives the ratchet motion, and reaches the purpose of secondary tension, and due to the characteristic of the unidirectional rotation of ratchet, mechanism can not exert an influence to tension once.Pull bar has used lever principle simultaneously, makes tightening force further amplify.This secondary take-up device can be used as appurtenances and joins in the bundling head, uses together with a pinch device, and pneumatic control system can be integrated with original system.
Description by above embodiment will help to understand the utility model, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
