Abstract

The utility model relates to a small six-shuttle mesh bag circular knitting machine which comprises a warp frame, a warp feeding device, a driving device, a host machine, an extension device, a drafting device, an elevated coiling device and six shuttles. The utility model is characterized in that a central angle which corresponds to a front and a back shuttle wheel of each shuttle is beta which is in the range of 25 and 35 DEG; the height of a curve of a cam rotary disc is H which is in the range of 100 mm and 130 mm, and a central angle which corresponds to the curve of the cam rotary disc is theta which is in the range of 30 and 45 DEG; a slide block is designed into a roller structure. The utility model has the advantages that the cross travel range of warp is shortened, and the opening time of the warp is also reduced so as to cause the shuttles to penetrate successfully. With the respect to power consumption, the reduction of the curve of the cam rotary disc not only lowers power consumption brought by the climbing of the shuttles to a motor, but also reduces the friction time of the slide block and a slide rod and lowers the power of a main motor. The improvement of all the structure of the utility model strengthens coordination degree among mechanical parts, lowers failure rate and enhances production efficiency.

Description

The small hexad shuttle mesh bag circular loom

Technical field

The utility model relates to a kind of small hexad shuttle mesh bag circular loom.

Background technology

Present stage holds the employed plastic mesh bag of article, has developed into and has adopted the circular loom braiding to form, and four shuttle mesh bag circular looms are to use equipment the most widely, and technical maturity is stable, and is lower but deficiency is mainly reflected in efficient.In order to overcome this deficiency, feasible way increases shuttle quantity exactly, six shuttle mesh bag circular looms become the developing direction of this equipment, for traditional four shuttle mesh bag circular looms, six shuttle mesh bag circular looms should enhance productivity about 50% in theory, but in the practical application, braiding output often improves less, even it is also low, reason is that six shuttle mesh bag circular looms machinery cooperates the precision prescribed height, so the fault probability is big, especially the interference between shuttle and the warp causes the phenomenon that breaks easily.

Summary of the invention

The purpose of this utility model provides a kind of working stability, and the low small hexad shuttle mesh bag circular loom of fault rate is to remedy the deficiency of prior art.

The technical scheme that the utility model provides is: the small hexad shuttle mesh bag circular loom: comprise through coil holder, let-off motion, transmission device, main frame, extension fixture, draw-gear, overhead wrap-up, six shuttles; Mainly comprise braided ring in the main frame, cam turntable, the threading tool, lubrication assembly, slide block, above-mentioned parts cooperatively interact, finish the braiding task, this is the total manner of execution of prior art, of the present utility model being characterized by: because six shuttle mesh bag circular looms are on same size, shuttle quantity and corresponding annex thereof have been increased, so require the dimensional accuracy of each parts more reasonable, could accurately cooperate the purpose that reaches smooth production mutually, be directed to the utility model, through a large amount of analysis of experiments, following specific constructive form is to realize the important assurance of purpose: the corresponding central angle of shuttle wheel is β before and after each shuttle, 25 °≤β≤35 °; The height of curve of cam turntable is H, 100mm≤H≤130mm; The central angle of the curve correspondence of cam turntable is θ, 30 °≤θ≤45 °; Rolling friction is changed in the sliding friction of original slide block, specifically is that slide block is set to roller shape, can produce relative rolling with cam turntable along fixing rotating shaft.

The beneficial effects of the utility model are: owing to adopt six shuttle, under the condition that does not change former cam turntable external diameter, just must reduce the cam turntable height of curve, this scheme main purpose is the stroke when shortening the warp intersection, reduce the time that warp is opened, make penetrating of shuttle more smooth; From power consumption, reduce the cam turntable curve, not only reduced the power consumption that shuttle brings motor when climbing, also reduced the fraction time of slide block and slide bar, cooperate the use of roller, reduce the power of main motor with this.The improvement of all structures has strengthened the degrees of coordination between the mechanical part, has reduced fault rate, has improved production efficiency.

Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:

Description of drawings

Fig. 1 is the utility model embodiment general assembly structural representation;

Fig. 2 is the structural scheme of mechanism of main frame among the utility model embodiment;

Fig. 3 is the structural representation of shuttle;

Fig. 4 is the cam turntable vertical view.

In the drawings, 1 is through coil holder, and 2 is let-off motion, and 3 is transmission device, and 4 is main frame, and 5 is extension fixture, 6 is draw-gear, and 7 is overhead wrap-up, and 8 is shuttle, and 9 are the shuttle wheel, and 10 is belt, 11 is braided ring, and 12 is cam turntable, and 13 is the threading tool, and 14 is slide bar, and 15 is slide block.

The specific embodiment

Embodiment:

Warp is by arriving braided ring 11 through coil holder 1, let-off motion 2 and threading tool 13.Cam turntable 12 rotates under the drive of motor, in rotary course, by high section thereon, low section and tiltedly section alternately contact with slide block 15,, so that slide block 15 edge tracks separately move up and down.Slide block 15 structures are two up and down roller structures in the utility model, roller contacts for line with cam turntable 12, effectively reduced frictional force, in addition, roller can be along the rotating shaft rotation of self in the process of moving up and down, and its purpose also reduces friction, and such benefit is that the transmission of exerting all one's strength is smooth more, being difficult for stuckly when turning to, is that the complete machine energy consumption is controlled effectively on the other hand.

The knee-action of slide block 15 passes to threading tool 13 by belt 10, threading tool 13 is produced to swing back and forth, the purpose of swing is to make two warps on the threading tool 13 that the action of opening with closed be arranged, and shuttle 8 can pass rapidly in the moment of opening with parallel, finishes the braiding task.

The intersection of warp realizes this technology patent applied for, the patent No.: 02276000.8 by the threading structure of signing an undertaking.

Finished fabric after braiding is finished is by extension fixture 5, draw-gear 6, overhead wrap-up 7 balings.

Owing to require in the said process cooperate degree of machinery higher, careless slightlyly will produce short, so when design selected most important for size, in the present embodiment, the central angle number of degrees β that shuttle 8 front and back shuttles are taken turns 9 correspondences 29 spends; Getting height difference H between high section and the low section on the cam turntable 12 is 120 millimeters; The central angle θ of cam turntable 12 curve correspondences is 38 degree.

Claims

1, small hexad shuttle mesh bag circular loom: comprise through coil holder, let-off motion, transmission device, main frame, extension fixture, draw-gear, overhead wrap-up, six shuttles, it is characterized in that: the corresponding central angle of shuttle wheel is β before and after the shuttle, 25 °≤β≤35 °; The height of curve of cam turntable is H, 100mm≤H≤130mm; The central angle of the curve correspondence of cam turntable is θ, 30 °≤θ≤45 °; Slide block is set to roller structure.
