Abstract
An active type cam opening device for a hyperspeed loom is characterized in that a main shaft of the loom drives a pair of bevel gear pairs through a pair of synchronous pulleys; the auxiliary bevel gears are coaxial with cam axles. A heald leveling mechanism coaxially drives a swinging arm axis in a cam box through a heald leveling handle seat with a heald leveling handle outside the cam box body; the swinging arm axis is in an eccentric axis structure. The center o1 of the main shaft is coaxial with the heald leveling handle seat; the center o2 of the eccentric shaft is the gyration centre of the swinging arm. Two locating points respectively corresponding to the heald leveling state and the loom state are arranged on the rotating path of the swinging arm axis coaxially driven by the heald leveling handle through the heald leveling handle seat. The cam axle and the swinging arm eccentric axis are arranged on an entire bracket in the box body, and are positioned on the same horizontal plane.

The specific embodiment
Referring to Fig. 1, cam box 4 is installed on the upper right support 28 in top of bottom right support 27, (back channel-section steel and preceding channel-section steel are on the unified horizontal plane among the figure with the back channel-section steel by preceding channel-section steel 20, do not draw) be connected with upper left support 22, lower-left support 23, be contained on the left wallboard 24 and right wallboard 26 of loom, the synchronous pulley 1 that is fixed together with loom main shaft, is paid 5 and 6 through spiral bevel gear and is made camshaft 7 drive conjugate cams 8 to rotate with 2 synchronous pulleys 3 with the driving cam casing through synchronously.The conjugate cam 8 that is fixed on the camshaft 7 is done motion mutually with two cam bawls 9 that are installed in the swing arm 10 (Fig. 4), and makes swing arm 10 do reciprocally swinging, and 11 is arm shaft.Swing arm 10 is by short connecting rod 13 and slide over linkage connector 15 on the main shedding arm 14 and drive main shedding arm 14 and swing.Make secondary shedding arm 19 and main shedding arm 14 do swing synchronously by long connecting rod 17 again.Main shedding arm 14, secondary shedding arm 19 drive two ends montant connector 21 and move up and down, and do the upper and lower opening motion thereby further drive heald frame 25.12 is that the flat locating piece, 31 of combining is that flat heddle handle seat, 32 spring holders for flat comprehensive pull bar, 33 are flat heddle handle.It is 1: 4,1: 5 or 1: 6 that the number of teeth of change synchronous pulley 1 can make the camshaft 7 and the speed ratio of loom main shaft.Cam box design has interior protective cover 30 and outer protective cover 29, when effectively preventing to adopt the dipping bath splash system lubrication and cause lubricating oil to spill immersion with dust and water.
Referring to Fig. 2, through the main spiral bevel gear 5 of 14 teeth the secondary spiral bevel gear 6 of 56 teeth is passed in transmission, secondary spiral bevel gear 6 is contained on the camshaft 7, drives camshaft 7 and rotates.Camshaft 7 and swing arm eccentric shaft 11 (Fig. 5) are contained on the box house support 34 (Fig. 3), and the rotation of camshaft 7 drives conjugate cam 8 motions, rotatablely moving of conjugate cam 8 is become the swing of swing arm 10 by cam bawl 9.The flat mechanism of combining adopts automatic positioning limit structure, and that has realized loom flatly combines operation, has also guaranteed the conjugation precision that the repetitive positioning accuracy of cam bawl and swing arm and conjugate cam are paid.The flat locating piece 12 of combining is contained on the casing 4, and flat heddle handle seat 31 (Fig. 7) is contained in flat combining in the locating piece 12 (Fig. 8).Positioning sleeve 36 is contained in flat combining in the locating piece 12, and spring holder (not drawing among the figure) is housed in the positioning sleeve 36, and pull bar 37 is connected with alignment pin, and handle 33 is contained in the flat heddle handle seat 31.Manually flatly combine mechanism's operation: pull out the flat pull bar 37 of combining, rotate counterclockwise flat heddle handle 33, flat heddle handle drives with the coaxial swing arm eccentric shaft 11 of flat heddle handle seat 31 and rotates, and realization swing arm 10 separates with cam 8.Promptly forward to flatly when combining location hole when the flat heddle handle seat, the flat spring holder of combining pull bar pins flat heddle handle seat 31, thereby realizes the flat work of combining.Otherwise, then realize the work of loom.When pulling flat heddle handle 33, flat heddle handle seat 31 forwards a hole B (Fig. 7) to by locating hole A, and promptly swing arm eccentric shaft 11 is just with O
1During for center rotational angle≤180 °, swing arm eccentric shaft center O
2Around center O
1Rotation, and displacement≤2e, two cam bawl simultaneous displacement≤2e in swing arm and the swing arm, swing arm eccentric shaft 11 is with O
1During for center rotational angle≤180 °, swing arm eccentric shaft center O
2Around center O
1Rotation, and displacement≤2e, two cam bawl simultaneous displacement≤2e in swing arm and the swing arm, and break away from major and minor conjugate cam, conjugate cam shedding mechanism operating position forwarded to and flatly combined the position this moment, and made whole heald frames concordant.Because swing arm eccentric shaft and camshaft are on the same box house support,, make swing arm eccentric shaft O by adjusting the flat heddle handle locating piece
2Relative O
1Be in the position of setting, thereby guaranteed the conjugation precision of swing arm and corresponding conjugate cam, realized that also all swing arms and corresponding conjugate cam break away from fully, and made swing arm be in given unique position.
Because the utility model adopts the one-level transmission, can reduce the center of gravity of complete machine, realize dipping bath splash system lubrication mode.Fig. 3 box house support is designed to monolithic construction, has reduced manufacturing and alignment error, and rack upper surface is the inclined-plane, is convenient to the user when changing fabric variety, opens the casing case, takes off the forward and backward bearing cap of camshaft, can take out camshaft and change cam bit.Camshaft center and arm shaft center are on the same horizontal plane, have improved the conjugation precision of swing arm and conjugate cam.Fig. 4 swing arm 10 is connected with cam bawl 9 by reference column 40 and clamping screw thread 41, and the structural design of swing arm provides assurance for camshaft center and arm shaft center are on the same horizontal plane, has realized that the center of gravity of complete machine moves down.Fig. 6 cam bawl is the vital part that rotatablely moving of cam is converted into the swing of swing arm.The life-span of cam bawl directly has influence on the service life and the rotating speed of complete machine.Cam bawl is made up of steel column 42, baffle plate 43,44, inner ring 45, outer ring 46.Clamping screwed hole 47 by three is connected with swing arm 10 with locating hole 48.
The utility model is applicable to putting or underlying active type cam opening device on water jet looms, air-jet loom, the Rapier looms.Therefore, above-mentioned use all should be within the protection domain of present patent application.
