Abstract

The utility model discloses a shuttle pushing mechanism of plastic cylinder braiding machine, which comprises a shuttle body 1, a pushing roller 4 with rotary power, a shuttle idler wheel 6, a shuttle wheel 7 and a big wire guiding frame 2. The shuttle pushing mechanism of plastic cylinder braiding machine is characterized in that the pushing roller 4 with rotary power is arranged under a warp thread separating and crossing point 3 and the shuttle idler wheel 6 extends out from the outer surface of the big wire guiding frame 2. The shuttle pushing mechanism of plastic cylinder braiding machine can not generate rupture of warp threads easily and can effectively improve the production efficiency of plastic cylinder braiding machines.

Description

A kind of shuttle propulsive mechanism of plastic cylinder braiding machine

Technical field

The utility model relates to a kind of shuttle propulsive mechanism of plastic cylinder braiding machine, mainly is the improvement to the shuttle propulsion mode of throwing parallel in the plastic cylinder braiding machine into, belongs to plastics package machinery field.

Background technology

At present, domestic and international disclosed plastic cylinder braiding machine all is to be main raw material with the polyolefin plastics flat filament, opens that the mating crossed belt has the shuttle picking of parallel and the equipment that is woven into a cloth with warp by rule.

Finish the shuttle of picking,, under powered,, finish the picking task along specific circular orbit operation across the warp of constantly advancing.The shuttle wheel fuses with the shuttle body in this course of work, and the roller that is used to accept thrust power is the key that influences the complete machine performance, from function aspects except accepting the thrust that is used to advance across warp, keep again not damaging warp, thus influence overall efficiency the most main indexes be exactly wire broken rate.

Existing type all adopts following two kinds of propulsive mechanisms:

One, the propulsive mechanism of middle propulsion mode: as shown in Figure 1, comprise shuttle body 1, advance roller 4, shuttle roller 6, shuttle wheel 7, big silk guide frame 2, the shuttle roller 6 that is used to drive 1 operation of shuttle body is arranged on the symmetrical centre place of shuttle body 1, in order to obtain maximum propulsive efficiency, but the propelling roller 4 that cooperates and have rotary power with shuttle roller 6 is in order to keep the relative position with shuttle roller 6, but be in a very disadvantageous position, because opening intersection point 3, warp is positioned on shuttle body 1 center line, this warp 5 is the most intensive, open simultaneously and hand over the slope maximum of warp curve at this place, so the warp that intersects is occupied than large tracts of land, propelling roller 4 at this place inevitably can interfere warp 5, though advance roller 4 to have a rotary power that is complementary with its speed of service at design aspect, but still can cause certain damage, thereby influence braid efficiency to warp 5.

Two, the propulsive mechanism of bottom propulsion mode: as shown in Figure 2, comprise shuttle body 1, advance roller 4, shuttle roller 6, big silk guide frame 2, shuttle roller 6 unites two into one with the shuttle wheel that cooperates with guide rail, and both are serially connected, and first half cooperates with guide rail, latter half is as roller, this kind mode with shuttle roller 6 be arranged on apart from warp open friendship place far away open the portion of telling somebody what one's real intentions are, because of having avoided advancing contacting of roller 4 and warp 5, so can not interfere phenomenon with warp 5.But because shuttle roller 6 is coaxial with the shuttle wheel, its surface has had and the identical linear velocity of shuttle wheel, for avoiding the contradiction on the speed, the propelling roller 4 that cooperates with it adopts with flowing mode and promotes 1 operation of shuttle body, there is not rotary power, in the course of the work, because the operation of shuttle 1 is single promotion, thereby shuttle roller 6 inevitably can take place contact unreal phenomenon with advancing roller 4, after the propelling roller 4 that has broken away from shuttle roller 6 runs out of steam, can't not obtain rotary power because of having to contact reliably with warp 5 again, finally can only rely on its inertia rotation, thereby cause reduction " stall " because of its superficial velocity.When the two again contact, because both superficial velocities are different,, damaged warp so, clamping warp 5 has therebetween been carried out " grinding stranding " when reaching surface both speed through interacting when identical, cause warp break.

Summary of the invention

The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of improved shuttle body propulsive mechanism is provided, and adopts this mechanism to be difficult for causing warp break, can effectively improve the production efficiency of plastic cylinder circular loom.

For realizing that the technical scheme that above-mentioned purpose of the present utility model adopts is: the utility model comprises the shuttle body, has the propelling roller of rotary power, shuttle roller, shuttle wheel, big silk guide frame, its design feature is that the propelling roller that will have rotary power is arranged on warp and opens below the intersection point, and shuttle roller part protrudes in the outside of big silk guide frame.

Keeping under the constant prerequisite of the existing type kind of drive; the utility model will be used to advance the propelling roller of shuttle operation to be arranged on warp to open below the intersection point; again with a part outside the outstanding big silk guide frame that is used to protect the shuttle body in shuttle roller edge; simultaneously two wheel surfaces are answered glue to reduce contact impact power; and the employing of propelling roller has rotary power; such configuration result can produce following effect: the propelling roller that has rotary power is opened under the place that joins because of being in; except that advancing contact-making surface, do not contact warp; can not damage warp; in the course of work; advance the linear velocity value and the tangential velocity of warp of roller surface design to be complementary in this position; be installed in shuttle roller on the shuttle body because of being that supporting roller does not have power; it can produce pure rolling under the acting in conjunction that advances roller and warp; thereby promote the motion of shuttle body; because of there not being speed difference between the two, can not damage the warp in the middle of being clamped in.When running out of steam when shuttle running body disengaging propelling roller, because of roller weight less, has very little the moment of inertia, the feasible shuttle roller part that protrudes in big silk guide frame outside, can accept and be close to stirring of warp that big silk guide frame slides, and continue to keep constant speed running, and because of the tangential velocity value of its velocity amplitude and warp is identical so can not produce the phenomenon of " losing speed ", thus the unanimity of the two superficial velocity when assurance contacts again.

The utility model has been protected the damage of warp to greatest extent, has reduced wire broken rate, has improved the complete machine operating efficiency.

Fig. 3 is the structural representation of the utility model embodiment.

The specific embodiment

For further specifying the utility model, the utility model is done further detailed description below in conjunction with accompanying drawing and the concrete example of implementing.

As seen from Figure 3, the utility model contains shuttle body 1, has the propelling roller 4 of rotary power, shuttle roller 6, shuttle wheel 7, big silk guide frame 2, the propelling roller 4 that has a rotary power be arranged on warp open intersection point 3 below, multiple glue in shuttle roller 6 surfaces and protrude in the outsides of big silk guide frame 2.

Advance roller 4 to contact with shuttle roller 6 on being installed in shuttle body 1, make it produce pure rolling, when running out of steam when shuttle body 1 operation disengaging propelling roller 4, because the ledge of shuttle roller 6 is under the stirring of the warp 5 of being close to big silk guide frame 2 slips, and continue to keep rotating, because of the tangential velocity value of its velocity amplitude and warp 5 is identical, thus the two superficial velocity unanimity when having guaranteed contact.
