Description

Structure improved inkle loom

The present invention relates to a kind of inkle loom, refer in particular to the inkle loom that a kind of transmission mechanism, pass cutter and lubricating arrangement wherein improved, this inkle loom mainly is that the non-return bearing in inkle loom power transmission shaft and the change-speed gearing group is reconfigured, make it can have better non-return effect, and cooperate the pass knife structure and the lubricating arrangement of a novelty, and it is good lubricated that whole transmission mechanism is obtained, thus can make its action more smooth and easy, with the attenuating fault rate, and have longer service life.

Existing inkle loom transmission mechanism all is to be power source by a motor, drive power transmission shaft via belt and slow down, drive the card axle with belt again and rotate, close cutter by the card chain drive, end in addition in the card axle then cooperates the change-speed gearing group to drive the action of drawstring axle, and its overall structure configuration is quite accurate; Only in existing inkle loom transmission mechanism, have and be not the disappearance that the people paid attention to, thereby promptly can cause the parts fault in use for some time and need repairing, cause the sizable puzzlement of user.

With regard to existing inkle loom structure, its transmission shaft bearing configuration structure promptly as shown in Figure 9, this power transmission shaft 81 is to be pivoted to be assembled in 80 of board both sides fixed heads, because the thickness of its fixed head 80 is limited, and can't organize bearing at power transmission shaft 81 and 80 assemblings of fixed head more, again because this type of inkle loom is when using, must guarantee that its power transmission shaft 81 can not reverse, in order to avoid have influence on the integral weaving operation, thereby in existing inkle loom power transmission shaft 81 structural arrangements, all be at the fixed head 80 of close drive sprocket 82 1 sides and the ball bearing 83 that 81 of power transmission shafts are assembled with supporting role power, and prevent the unidirectional needle bearing 84 that power transmission shaft 81 reverses in other side fixed head 80 and 81 assemblings of power transmission shaft, though this design can provide power transmission shaft 81 to be pivoted outside the effect, reach the effect that prevents that power transmission shaft 81 from reversing simultaneously, but its global design does not reach perfect degree.

If can be learnt with regard to configuration aspects analyze, in existing inkle loom power transmission shaft 81 bearings configuration, though it is assembled with ball bearing 83 at power transmission shaft 81 ends near drive sprocket 82 sides, thereby can bear the strength of major part, but it still can't overcome the shortcoming of sidewindering needle bearing 84 stress destructions in addition, because unidirectional needle bearing 84 effects own are to be to provide a single effect, and be not in order to bear strength, so on existing inkle loom power transmission shaft one end, supporting strength is provided and prevents to reverse double effects with unidirectional needle bearing 84, will inevitably make this unidirectional needle bearing 84 promptly cause damage in use for some time because of can't bear load, it carries out repair and replacement once damage promptly must be shut down whole inkle loom, thereby can have influence on whole processing operation, wherein more serious, be when the unidirectional needle bearing 84 of these power transmission shaft 81 sides damages, often unknown by the people, to shut down and can not reach seasonal inkle loom, that is this power transmission shaft 81 still can be rotated further after this unidirectional needle bearing 84 damages, but it is on-stream then unavoidably because of causing the reverse of its power transmission shaft 81 between start and stop, thereby can make the product that weaves by the gross defective, scrap and accuse, this just more causes production firm's considerable damage; Though the phenomenon that this unidirectional needle bearing 84 is easy to damage exists for a long time, is subjected to the restriction of board fixed head 80 and 81 relative positions of power transmission shaft, and can't improves always.

Existing inkle loom stencil cutter-closing 85 structures then as shown in Figure 10, its integral body is that the metallic plate by a bending is constituted, the inboard in section knee is pivoted with an action pulley 86 for the ejection of card chain therein, end then is provided with a pivoted hole 87, be each sheet to be closed cutter 85 be located in respectively between two sandwich sheets 88 during its assembling, sandwich sheet 88 then is to be fixedly arranged on the cross bar 90 of board top with erection bolt 89, this kind structural design quite bothers when utilization, especially when inkle loom when assembling or keep in repair, more can cause processing personnel Equivalent's puzzlement, because its each sheet closes the sandwich sheet 88 that cutter 85 all need cooperate both sides, wear plate, erection bolt 89 members such as grade are assembled, and the pass cutter 85 that has at least in inkle loom surplus in the of ten slice, that is no matter be when assembling or dismounting maintenance, all must be in the face of at least four, 50 part, not only waste time and energy, also very easily the time cause error and have influence on the utilization of whole inkle loom in assembling.

Moreover; in machine-operated cutter 85 structures of existing ribbon; any oil supply system is not provided; that is it must be by operating personnel at set intervals to the pivoted hole 87 that closes cutter 85 and action pulley 86 thereof the lubricating oil of partly annotating in when utilization; make its very inconvenience when utilization; especially when being lubricated, must shut down again; and easily have influence on the processing efficiency of operation; simultaneously because it is when operating; bearing in the pivoted hole 87 of pass cutter 85 and action pulley 86 thereof can't obtain appropriate lubricating; thereby very easily cause wearing and tearing; thereby promptly need in addition repair and replacement in use for some time; and in the maintenance cost that has increased integral device virtually, and cause the reduction of working (machining) efficiency.

If come machine-operated cutter 85 structures of existing ribbon are analyzed by another angle, then can find, why existing pass cutter 85 is designed to crooked shape, its main purpose is to make its action pulley 86 and terminal pivoted hole 87, with and most advanced and sophisticated motion end 851 be located along the same line, be beneficial to regular event, make action pulley 86 simultaneously the time by the ejection of card chain, can not produce skew, but when reality is used, because action pulley 86 is to be hubbed at a side of closing cutter 85, thereby to make the shaft strength of action pulley 86 be a side direction stressed, thereby in the mechanical action that constantly repeats, often will make bearing produce the loose even distortion of wearing and tearing, and need in time to be changed, in order to avoid have influence on the braiding of product; In existing inkle loom, very easily damage because close the member of cutter 85 parts, often dismantled maintenance and take, so will close cutter 85 is fixed in the mode of sandwich sheet 88 clampings, so that when maintenance, need not dismantle all pass cuttves 85, and only the pass cutter of damaging 85 must be dismantled and can be changed, this kind design concept is a basic mistake originally, because perfect Machine Design, when increasing its service life to reduce its fault rate is principle, and can not do the change of structure in order to yield to maintenance, Here it is causes existing inkle loom operating personnel to look the reason that its pass cutter 85 structural repairs are replaced by normal condition, but it is to the influence of production efficiency and maintenance cost, and former absolutely not designer institute is expectable.

Again with existing inkle loom change-speed gearing group structure, its whole change-speed gearing group structural arrangements is identical with the structure that the present invention proposes, be to drive by the shaft-driven driven wheel of transmission with one, via an idle pulley transmission, and after the change-speed gearing deceleration through two replaceable adjustment, the driven gear that drives drawstring axle outer end rotates, driving the drawstring axle according to this rotates, because the main effect of drawstring axle is the speed that is to control inkle loom drawstring when weaving, that is be in order to control the weft density of finished product, when inkle loom running and drawstring axle when doing intermittent the rotation, no way allows the drawstring axle produce any revolution, because once drawstring axle generation bow tie, then will inevitably make originally tighten through LSOR, it is disorderly that the braiding of parallel is produced, thereby can make its finished product form defective products, the action of whole inkle loom is also influenced even, and parts are damaged.

Thereby in existing inkle loom change-speed gearing group, be provided with a non-return structure, to prevent that its drawstring axle from producing revolution in intermittent rotation, but with this type of inkle loom structure that all parts of the world were produced, they all are the designs of continuing to use Britain, and as shown in Figure 11, one group of unidirectional needle bearing 92 is assembled in Sui takes turns on 91 central shafts 93, leading because of being that needle bearing 92 structures are comparatively fragile of this design can't be born bigger load, and be easy to damage, so it is arranged in the idle pulley 91, once needle bearing 92 damages, can be easily with its dismounting and change, but on reality is used, have suitable shortcoming;

In inkle loom change-speed gearing group, in order to cooperate different weft densities, thereby must optionally change its change-speed gearing, idle pulley 91 then only is for the change-speed gearing that cooperates different chi rain and in addition transmission and being provided with, this idle pulley 91 is to be arranged between driven wheel and the change-speed gearing, thereby still must can drive the drawstring axle via two change-speed gearings and a driven gear at the rear of its drive line, weft density to product when existing inkle loom uses requires suitable height, but because can't accurate control the intermittence between change-speed gearing and driven gear, especially will inevitably produce wearing and tearing at long-term its gear train of back that uses, thereby the unidirectional needle bearing 92 real drawstring axles that can't prevent accurately that are arranged in the idle pulley 91 produce revolution, that is in the intermittence of drawstring axle is rotated, the still revolution that can produce a little because of the gap between idle pulley 91 and change-speed gearing and driven gear, thereby its product weft density that weaves is affected, and the quality of its finished product is significantly reduced.

Moreover; the needle bearing of in existing inkle loom non-return being used 92 is arranged in the idle pulley 91; it originally is exactly replacing for the ease of unidirectional needle bearing 92; this design can be avoided dismantling power transmission shaft or drawstring axle and be made or have much ado when changing; but because the design of unidirectional needle bearing 92 promptly is not to be used to bear load originally; simultaneously because the diameter of idle pulley 91 is limited; and can't adopt comparatively strong and the bigger needle bearing of diameter; thereby when the bigger product of braiding weft density; will inevitably make the stressed bigger of idle pulley 91; and cause its needle bearing 92 stressed excessive and damage; make it use regular meeting often because of the damage of needle bearing 92 and must shut down in addition Replacement and Repair; make needle bearing 92 become the integrally-built weak link of inkle loom on the contrary; the user often promptly can damage because of the needle bearing 92 that is assembled in the idle pulley 91 in use for some time; change and must shut down; also can cause simultaneously the product declaration that is weaving to scrap, this also be the non-return structure design of the change-speed gearing group in the existing inkle loom transmission mechanism superior inadequately due to.

Therefore, first purpose of the present invention is: adopting provides the strength of cardan-shaft suspension by the ball bearing at power transmission shaft two ends, and can guarantee the stable pivot of power transmission shaft, will not be because of stressed and make its bearing impaired.

Second purpose of the present invention is: adopt and assemble one group of unidirectional needle bearing by the bearing holder (housing, cover) of being assembled on the power transmission shaft one side fixed head, by this group needle bearing fully not under the situation of supported strength, its due reverse effect that prevents is provided, and makes overall structure have longer service life.

The 3rd purpose of the present invention is: unidirectional needle bearing directly is arranged between drawstring axle head and the driven gear bushed bearing, thereby can directly control the rotation of drawstring axle, thereby can guarantee that the drawstring axle can not have a little rotating phenomenon because of the gear clearance of change-speed gearing group, thereby the quality of product is more improved.

The 4th purpose of the present invention is: adopt the design of bushed bearing; can in the driven gear of drawstring axle head, assemble two groups of needle bearings that diameter is bigger simultaneously; thereby can make it when utilization, have better robustness; and can not damage because of stressed being easy to; thereby can guarantee inkle loom smoothness in use, can overcome existing inkle loom needs usually to shut down the shortcoming of changing needle bearing.

The 5th purpose of the present invention is: with the pass knife structure of combined type, the pulley that will move is located in and closes in the cutter body, and make the motion end at action pulley and pivoted hole and tip can be really on same straight line, and make the pass cutter more smooth and easy when action, also can make simultaneously the bearing of action pulley can be stressed reposefully, thereby can have longer service life.

The 6th purpose of the present invention is: with a fixed axis pivoted hole that each sheet closes cutter is run through mutually, and be fixed in the board, set up in the pivot joint mode of a suspension type closing cutter, make it more convenient and rapid when assembling.

The 7th purpose of the present invention is: be provided with oil filler point and nozzle opening in the fixed axis of suspention pass cutter, thereby the oil feed pump that can utilize the card axle to drive constantly is sprayed onto lubricating oil on the bearing and action pulley that closes in the cutter pivoted hole, thereby it is lubricated fully that it is obtained, and makes whole more smooth and easy when action.
