The specific embodiment
See also Fig. 1 to Fig. 3, the utility model provides a kind of yarn-feeding device, especially refer to a kind of yarn-feeding device that is provided with broken yarn testing agency 1, this yarn-feeding device can be the yarn-feeding device of electromagnetic clutch type, motor type or other patterns, do not limited, present embodiment discloses a kind of yarn-feeding device of electromagnetic clutch type.
This yarn-feeding device comprises a body 2 and a yarn storage wheel 3, yarn storage wheel 3 rotatably is arranged at body 2, yarn storage wheel 3 can be connected in a belt pulley 4 by power transmission shaft (figure slightly), belt pulley 4 can be in order to mesh with belt strip member such as (figure slightly), use drive pulley 4 and yarn storage wheel 3 rotations, thereby utilize yarn storage wheel 3 to drive the action that yarn stores up yarn and send yarn.Therefore in the present embodiment, this yarn-feeding device is an electromagnetic clutch type, is provided with an arrangement of clutch (figure is slightly) between power transmission shaft, so as the joint that utilizes arrangement of clutch with separate the transmission of controlling rotary power.When arrangement of clutch engaged, turn power can be passed to yarn storage wheel 3, to drive yarn storage wheel 3 rotations, made yarn be wrapped in the action of storing up yarn on the yarn storage wheel 3.When arrangement of clutch separated, turn power interrupted immediately, and yarn storage wheel 3 is stopped operating to end the action of storage yarn.If the yarn-feeding device of motor type then can utilize a motor (figure slightly) directly to drive yarn storage wheel 3 rotations.
Can further liftably be provided with one and press yarn circle 5 in this enforcement on yarn storage wheel 3, this pressure yarn circle 5 is ring-like lamellar body, presses yarn circle 5 to descend because of weight own and to suppress in yarn storage wheel 3 lower edges.The yarn that is wound on the yarn storage wheel 3 can pass between pressure yarn circle 5 and yarn storage wheel 3 lower edges, and it is online to utilize pressure yarn circle 5 to suppress in yarn, and it is comparatively stable that yarn is carried.
This broken yarn testing agency 1 is arranged on the body 2, this broken yarn testing agency 1 comprises an epimere broken yarn bar 11 and a yarn introduction member 12, this epimere broken yarn bar 11 is hubbed on the body 2 swingably, this epimere broken yarn bar 11 has an articulated section 111 and a contact part 112, the articulated section 111 of this epimere broken yarn bar 11 is articulated in body 2, in order to this epimere broken yarn bar 11 is hubbed on the body 2.This epimere broken yarn bar 11 can be done upper and lower swing, makes epimere broken yarn bar 11 at a primary importance a(as shown in Figure 3) and a second place b(shown in Fig. 2 A) between move, second place b is positioned at the below of primary importance a.This contact part 112 can be a cross bar, makes yarn can pass the lower edge of contact part 112, so that utilize the tension force of yarn to support contact part 112, this epimere broken yarn bar 11 is maintained at primary importance a.
The material of this yarn introduction member 12 does not limit, and can adopt materials such as pottery or metal.This yarn introduction member 12 is arranged on the body 2, and this yarn introduction member 12 is in abutting connection with epimere broken yarn bar 11.This yarn introduction member 12 can utilize a holder 13 to be fixed on the body 2, also be that yarn introduction member 12 can utilize modes such as clamping to set in advance in holder 13, again this holder 13 is fixed on the body 2 in modes such as screw lock, yet these yarn introduction member 12 fixing modes do not limit.
This yarn introduction member 12 has a thread guide eyelet 121, this thread guide eyelet 121 runs through the front end and the rear end of yarn introduction member 12, this thread guide eyelet 121 is preferably elongated hole, also be the height h of thread guide eyelet 121 greater than width w(shown in Fig. 2 B), width w also can be described as the lateral dimension of thread guide eyelet 121, and height h also can be described as the longitudinal size of thread guide eyelet 121.The bottom of thread guide eyelet 121 preferably but do not limit and have an opening 122, the bottom of thread guide eyelet 121 has opening 122, can make thread guide eyelet 121 form an inverted U hole.This thread guide eyelet 121 also can be non-elongated hole, as circular port etc., as long as thread guide eyelet 121 bottoms have opening 122, just can reach the effect that yarn is dropped downwards basically.
In addition, disclosed as Fig. 4, in the present embodiment, this thread guide eyelet 121 is an elongated hole, but the bottom of this thread guide eyelet 121 does not have above-mentioned opening 122, to form the thread guide eyelet 121 of bottom lock, because thread guide eyelet 121 is an elongated hole, also can reach the effect that yarn is dropped downwards.
The hypomere broken yarn bar 14 that also can further be pivoted on this body 2, this hypomere broken yarn bar 14 is positioned at the below of yarn storage wheel 3, also can be in order to detect yarn storage wheel 3 broken yarns, not have the situation of yarn.
Broken yarn of the present utility model testing agency 1 can be in order to detect yarn storage wheel 3 broken yarns, there be not the situation of yarn, when yarn storage wheel 3 normal reservoir yarns, when sending yarn, can utilize the tension force of yarn to support contact part 112, this epimere broken yarn bar 11 is maintained at primary importance a(as shown in Figure 3), this moment is for storing up yarn normally, sending the yarn situation.When yarn storage wheel 3 broken yarns, when not having yarn, yarn in the thread guide eyelet 121 loses tension force and drops downwards, this epimere broken yarn bar 11 is rocked to second place b(immediately shown in Fig. 2 A), then can utilize a sensor that is arranged at body 2 inside (figure slightly) sensing this moment, use and judge on the yarn storage wheel 3 not have yarn, and signal is transferred to corresponding caution cresset (figure slightly) send caution light, show the situation that broken yarn takes place, do not have yarn, simultaneously can control automatic stopping, to avoid causing the flaw of fabric.
Yet the above only is a preferred embodiment of the present utility model; non-ly be intended to limit to scope of patent protection of the present utility model; so the equivalence of using the utility model specification and graphic content to do such as changes; all in like manner all be contained in the claim protection domain of the present utility model, close and give Chen Ming.
