The push bar equips with a bearing on one end then connects with the eccentric cam, and is fixed to the steel guide bar on the other end. The servo motor controls the rotation direction and angle of the eccentric cam according to pattern design signals sent by the CPU control circuit, and applies the shogging produced by the eccentric cam on the steel guide bar through the push bar in a straight line, coordinates with the reset device installed on the head of the steel guide bar to accomplish the overall shogging of the steel guide bar. Hence, the present utility model provides simple control principle, flexible operation, simple error correction process, rapid operation of the machine. Since the pattern design and adoption are fully computerized, pattern changing can be conducted rapidly which not only ensures the shogging precision, but also reduces the cost greatly.

Description

Electronic shog controller

Affiliated technical field:

The utility model relates to a kind of electronic shog controller.

Background technology:

Traditional mechanical type is combed executing agency's complex structure of joint warp knitting machine more, by the control of chain piece, requirement on machining accuracy height.The joint number purpose increases and the expansion of flower type along with combing, and chain piece sum even ten hundreds of is heavy in ton, changes the chain piece and requires great effort very much, turns a cover flower type and will stop production several weeks, causes some producers to lose the chance of many orders.

In many kinds, under the market economy effect of small lot, mechanical type is combed the intelligentized transformation of joint warp knitting machine more, improving its automaticity has been imperative.In order to improve the competitiveness of product in market, replace traditional mechanical transverse-moving mechanism with the electronics transverse-moving mechanism and become very urgent.Adopt advanced computer technology and electric control technology to transform prior mechanical flower comb transverse-moving mechanism, will improve the lace production efficiency of products greatly, promote the quality and the class of product.

At present, leading over domestic through research and application aspect the volume electronics horizontal movement abroad.Ka Er Meyer company as Germany develops and has used EL electronics horizontal movement system on the high speed warp knitting machine, on multi-bar warp knitting machine, used SU electronics horizontal movement system, on lace machine of new generation, flower comb and ground comb have all adopted servo-controlled electronics horizontal movement system, the LIBA company of Germany develops on the high speed warp knitting machine and has used ELS electronics horizontal movement system, has used ESJ electronics horizontal movement system on jacquard warp knitting machine.Along with the continuous development of China's warp knitting machine manufacturing technology, developing homemade flower comb electronics horizontal movement control system has become a kind of inexorable trend.

In numerous crossing systems, mainly by following several: first kind: by chain piece control flower type comb joint traversing technology, its tuberculosis principle is to utilize the differing heights of chain piece to be converted into laterally mobile by big blade, every a lot of chain piece of comb joint drive, then entire machine will drive tens strings, and ten hundreds of chain pieces turn round, and this just just causes machine run speed slow, safeguard to be difficult for, change the shortcoming of flower type trouble; Second kind is SU Electronic comb joint crossing system, its structural principle is to control the flower comb by slide assemblies, control slide assemblies by electromagnetic component, thereby form traversing path distance according to the path of determining, this transverse-moving mechanism has been removed the processing of chain piece from, assembling, dismounting, it is easy to change the flower type, can produce the many kind flowers of the small lot type of less expensive, production automation degree is higher, and weak point is that its slide assemblies complex structure and flower comb maximum sideslip distance are little, has limited the design of colored type to a certain extent; The third is a steel wire electronics horizontal movement system, and its structure is mainly by servomotor, and the steel wire flower is combed, and returning device is formed.The groundwork principle is as follows: each steel wire flower comb connects a servomotor, carry out transverse motion by servomotor, cooperate by returning device simultaneously and carry out, this crossing system, it is fast to carry out speed, and the traversing amount of floricome is big, be easy to safeguard, production efficiency height, weak point are that cost is too high, are unsuitable for extensive popularizing and use.

Summary of the invention:

It is a kind of by computer control, simple in structure, traversing accurate that the purpose of this utility model is to provide, production efficiency height, lower-cost many comb joint lace machine electronic shog controllers.The purpose of this utility model is to realize like this, described electronic shog controller, comprise the steel belt comb joint, servomotor, return spring and cpu control circuit, its design feature is that eccentric cam is driven swing and all is fixed on the cam arm by servomotor, push rod passes push rod positioning seat and baffle plate respectively, push rod one end is equipped with bearing and joins with eccentric cam, the other end directly is fixed on the steel belt comb joint, servomotor is controlled direction and angle that eccentric cam rotates according to the signal of the colored type design that cpu control circuit sends, the traversing amount that eccentric cam is produced saves in steel belt comb by the push rod linear function, and the returning device that cooperates steel belt comb section header portion to be provided with is finished the whole traversing of steel belt comb joint.The purpose of this utility model also can be achieved through the following technical solutions, described electronic shog controller, its characteristics are that returning device is by return drag hook, guide wheel, steel cable and return spring, return drag hook one end is fixed in the steel belt comb section header portion, and the return drag hook other end connects steel cable and is connected with return spring through guide wheel.Described electronic shog controller, its characteristics be returning device by pneumatic of return drag hook, guide wheel, steel cable and return, return drag hook one end is fixed in the steel belt comb section header portion, the return drag hook other end connects steel cable and is connected through pneumatic of guide wheel and return.Described electronic shog controller, its characteristics are that baffle plate is provided with a plurality of guide rod holes that the steel belt comb joint can be installed that stagger up and down.The utlity model has following advantage: because the eccentric cam curve is to pass through accurate Calculation in the utility model, make different angles produce the traversing amount of differing needles distance, be used servomotor, directly act on the steel belt comb joint, not through other transmission mechanism, so guaranteed the traversing accuracy of steel belt comb joint, machine run speed is fast, the traversing distance of steel belt comb joint is big.The utility model has only utilized servomotor simultaneously, eccentric cam, and compact conformation cooperates the guide rod hole on the baffle plate, and the installation of staggering up and down makes board that more comb joint can be installed, and satisfies more flower type design requirement.Because use computer control servomotor, the control relation is simple, flexible operation, error correction procedure is simple, production automation degree height, machine operating speed is fast.Because the design of flower type uses realization computerized fully, therefore flower type replacing speed is fast.The utility model has only been used servomotor and eccentric cam simultaneously, and return spring had both guaranteed traversing precision, had reduced cost again significantly, and the machine of same function only is equivalent to 1/8th left and right sides costs of German import.
