Abstract
The utility model discloses a conveying chain plate tensioning device which comprises a rack, a conveying chain plate, a cylinder, a chain, a slider guiderail seat, approach switches, a support, a slider seat, a driven shaft, chain wheels and a pneumatic-electricity converter, wherein the pneumatic-electric converter is arranged on a gas supply pipe of the cylinder, the approach switches are arranged at the front and back of the left and right chain wheels and are used for detecting the positions of the chain wheels, the pneumatic-electricity converter and the approach switches both receive and send signals to a PLC (Programmable Logic Controller) for processing, a main transmission motor can be possibly electrified only when the cylinder is inflated, equipment can drive or normally work only when the left chain wheel and the right chain wheel are both positioned between the approach switches in the front and the back and are not detected, thereby being capable of ensuring that the conveying chain plate can start or normally work only on the premise of being fully tensioned; stopping can be conducted in time due to insufficient pressure of an air source, air stopping of the cylinder and breakage of the chain in working, so as to effectively protect the equipment from being damaged, thereby ensuring that the conveying chain plate runs more stably and more reliably.
Description
Affiliated technical field
The utility model belongs to the link plate tensioning device on the textile industry fiber drying machine.
Background technology
At present, transporting chain plate tightening device on the fiber drying plant is used general, this installs normally transporting chain plate main gear end and fixes, the two ends of driven shaft are equipped with sprocket wheel, take-up housing, move the dragging chain sprocket wheel chain is strained with cylinder or screw mandrel top or pulling take-up housing, driven shaft, thereby will be fixed on transporting chain plate tensioning on the chain.The equipment preparation obviously is better than the screw mandrel tensioning with the cylinder tensioning certainly relatively, because the screw mandrel degree of tension can not affect expanding with heat and contract with cold of chain along with the temperature rise of drying room and change.And
Use the cylinder tensioning, also there is at present following defective: the one, because of negligence of operation, starting outfit when inadequate without source of the gas or bleed pressure, unexpected cylinder is stopped the supple of gas or steam when perhaps working, transporting chain plate is in relaxed state, often can cause because chain is folding and squeeze bad carrier bar, chain breaks away from sprocket wheel even frame is drawn distortion when serious; The 2nd, if rupture suddenly because of chain during work, have little time to stop, easy-to-draw bad equipment, squeeze bad carrier bar.
Summary of the invention
For overcoming the deficiency of existing transporting chain plate tightening device, the utility model proposes a kind of transporting chain plate tightening device that equipment is had defencive function.
The technical solution of the utility model is achieved in that the transporting chain plate tightening device is comprised of frame, transporting chain plate, cylinder, chain, slide block guide rail seat, approach switch, bearing, take-up housing, driven shaft, sprocket wheel, pneumatic-to-current converter etc., and the driven shaft that sprocket wheel, take-up housing all are equipped with in transporting chain plate tightening device two ends is installed in the left and right sides of frame by the slide block guide rail seat; Cylinder is fixed on the slide block guide rail seat, and cylinder piston rod links to each other with take-up housing, installs the compressed air line with pneumatic-to-current converter that links to each other with cylinder; Transporting chain plate is fixed on the chain, and chain hangs on the sprocket; Approach switch is fixed on and forms one on the bearing, is installed in respectively on the correct position of sprocket wheel front and back, the left and right sides again, and the jam nut of adjusting on the approach switch makes itself and sprocket wheel to suitable distance, approach switch and pneumatic-to-current converter) all link to each other with PLC by wire.Be installed in the pneumatic-to-current converter on the cylinder supply air line, be used for detecting the approach switch of chain wheel location with the front and back that are installed in left and right sprocket wheel, to receive that all signal passes to PLC and processes, the cylinder charge main driving motor just might get electric, left and right sides sprocket wheel only has all before and after it between approach switch and be not detected, and equipment could be driven or work.
Its advantage is to guarantee that transporting chain plate only could drive or work under the prerequisite of fully tensioning; Bleed pressure is inadequate in the work, cylinder is stopped the supple of gas or steam, chain breakage all can in time stop and effectively protect equipment not damaged, thereby guarantees that the transporting chain plate operation is more reliable and more stable.
Description of drawings
Fig. 1 is transporting chain plate tightening device scheme drawing;
Fig. 2 is transporting chain plate tightening device schematic diagram.
Among the figure: 1. transporting chain plate, 2. cylinder, 3. chain, 4. slide block guide rail seat, 5. approach switch, 6. bearing, 7. take-up housing, 8. driven shaft, 9. sprocket wheel, 10. frame, 11. pneumatic-to-current converters.
The specific embodiment
Further specify below in conjunction with accompanying drawing.
The driven shaft (8) that sprocket wheel (9), take-up housing (7) all are equipped with in transporting chain plate tightening device two ends is installed in the left and right sides of frame (10) by slide block guide rail seat (4); Cylinder (2) is fixed on the slide block guide rail seat (4), and cylinder (2) piston rod links to each other with take-up housing (7), installs the compressed air line with pneumatic-to-current converter (11) that links to each other with cylinder (2); Transporting chain plate (1) is fixed on the chain (3), and chain (3) hangs on sprocket wheel (9) tooth; Approach switch (5) is fixed on the upper one that forms of bearing (6), be installed in respectively again on the correct position of left and right sides sprocket wheel (9) front and back, the jam nut of adjusting on the approach switch (5) makes itself and sprocket wheel (9) to suitable distance, and approach switch (5) all links to each other with PLC by wire with pneumatic-to-current converter (11).During the need of work tensioning, open pressurized air, intratracheal pressure makes pneumatic-to-current converter (11) send signal and passes to PLC, if bleed pressure is up to standard, cylinder (2) air inlet piston rod protracts, promote the integral body such as take-up housing (7), driven shaft (8), sprocket wheel (9) and move forward certain distance between the sprocket wheel front and back approach switchs (5), thereby with fully tensioning of transporting chain plate (1), PLC makes main driving motor get the electric stand-by state that enters, and starting main driving motor can work; If bleed pressure is inadequate, cylinder (2) air inlet piston rod protracts, the integral body such as promotion take-up housing (7) move forward, but because of the large miles of relative movement of resistance inadequate, transporting chain plate this moment (1) is not tensioned, the approach switch (5) that is installed in rear side detects sprocket wheel and sends signal and pass to PLC, and the main driving motor outage can not start work.Just at work, if source of the gas is stopped the supple of gas or steam or pressure is inadequate, because of resistance cylinder piston rod retrude, transporting chain plate this moment (1) is not tensioned, the approach switch (5) that is installed in rear side detects sprocket wheel and sends signal and pass to PLC, and main driving motor is de-energized parking; If chain breakage, cylinder (2) piston rod continues to move forward because pushing away take-up housing (7) etc. without large resistance, and the approach switch (5) that is installed in the front side detects sprocket wheel and sends signal passes to PLC, and main driving motor is de-energized parking immediately.
