Abstract

The utility model relates to a weft seeking device for loom, which comprises a weft seeking clutch and a low speed clutch disposed on the central shaft in the heald reversing box, and an upright shaft box and let-off takeup wheel connected to the central shaft. A main transmission connects with the weft seeking clutch by an input wheel, and a weft seeking electric motor connects with the low speed clutch by a driving device, and the upright shaft box and let-off takeup wheel are separately arranged on both sides of the heald reversing box. The low speed clutch is arranged on the central shaft outside of the heald reversing box and is beside of the let-off takeup wheel. This device has the following technical advantages in that firstly, the outputs of the two motions of upright shaft box and the let-off takeup are separately on both sides of the heald reversing box and the main transmission, the space can be used by the upright shaft box is increased and the carrying capacity of the upright shaft box is improved; secondly, this device can realize the function of low speed; thirdly, the two clutches both adopt electromagnetic force to drive, and the traverse and the secondary force is small and the accuracy of movement is high.

Description

A kind of automatic latitude seeking device of loom,

Technical field

The utility model relates to the automatic latitude seeking device on a kind of loom, it can be transferred to the main motion of loom opening, the warp let-off, batch, and when the needs automatic latitude seeking, by device with motor-driven, drive opening, the warp let-off, takeup motion, belong to field of textile machinery.

Background technology

Loom should be sought according to different staplings situations, the alignment fell in weaving behind the staplings automatically, makes loom weave defects such as no rare grade of back again, satisfies requirements of weaving process.Existing automatic latitude seeking device as shown in Figure 1, its structure comprises seeks latitude clutch 14 and clutch 15 at a slow speed on the central shaft 18 that places in the inverted heddle box 13, vertical shaft box 11 and warp-feeding and reeling belt wheel 17 that one side of central shaft 18 links to each other, main transmission by an input belt wheel 12 with seek latitude clutch 14 and link to each other; Promptly this is sought the latitude clutch and closes, and the throw-out-of clutch at a slow speed of arranged adjacent is given to central shaft 18 with motion, and then passes to vertical shaft box 11 and warp-feeding and reeling belt wheel 17; And when automatic latitude seeking, this device with seek latitude motor 16 by series of gears 19 moving through clutch at a slow speed, promptly seek latitude throw-out-of clutch, clutch adhesive at a slow speed, central shaft is passed in motion, and then pass to vertical shaft box 11 and warp-feeding and reeling belt wheel 17.The defective that above-mentioned automatic latitude seeking device exists mainly contains: 1. a liang clutch is mechanical type, and traverse is big, and additional drag is also big, causes easily and botches routines; 2, the disengagement of two clutches, to close be interlock, cannot realize moving at a slow speed; 3 have two motion outputs between main transmission input belt wheel and column plate, i.e. motion output of vertical shaft box and the motion output that the warp let-off is batched, because the space is limited, the moment of torsion that vertical shaft box can bear is lower.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of action at a slow speed that can realize is provided, and improves the loom automatic latitude seeking device of vertical shaft box bearing capacity.It comprises seeks latitude clutch and clutch at a slow speed on the central shaft that places in the inverted heddle box, and the vertical shaft box and the warp-feeding and reeling belt wheel that link to each other on the central shaft, main transmission by an input belt wheel with seek the latitude clutch and link to each other, and one seek the latitude motor and also link to each other with clutch at a slow speed by a transmission device, the be placed in both sides of inverted heddle box of described vertical shaft box and warp-feeding and reeling belt wheel.

Described seek the latitude motor by a transmission device that constitutes by reduction box and pair of sprocket with link to each other by the power-actuated clutch at a slow speed of electromagnetism, with this at a slow speed the latitude clutch of seeking settled of clutch coaxial also be the electromagnetic force driving.

Described clutch at a slow speed places on the central shaft in the inverted heddle box outside, put adjacent with warp-feeding and reeling belt wheel.

The utility model compared with prior art has following technological merit: 1 vertical shaft box and send the output of batching two motions respectively in the both sides of inverted heddle box and main transmission input, increased the space that vertical shaft box can use, and improved the bearing capacity of vertical shaft box; 2 can realize function at a slow speed; 3 liang of clutches all adopt electromagnetic force to drive, and traverse is little, and additional force is little, the degree of accuracy height of action.

Description of drawings

Fig. 1 is the structural representation of existing automatic latitude seeking device.

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Be described in detail below in conjunction with 2 pairs of the utility model of accompanying drawing: shown in the accompanying drawing 2, the utility model includes seeks latitude clutch 24 and clutch 25 at a slow speed on the central shaft 28 that places in the inverted heddle box 23, and continuous vertical shaft box 21 and warp-feeding and reeling belt wheel 27 on the central shaft 28.Main transmission by an input belt wheel 22 with seek latitude clutch 24 and link to each other, and one seek latitude motor 26 and also pass through a transmission device and link to each other with clutch 25 at a slow speed, the be placed in both sides of inverted heddle box 23 of described vertical shaft box 21 and warp-feeding and reeling belt wheel 27.

Described in the utility model seek latitude motor 26 be by a transmission device that constitutes by reduction box 29 and pair of sprocket 20 with link to each other by the power-actuated clutch at a slow speed 25 of electromagnetism, with this at a slow speed the latitude clutch 24 of seeking of clutch 25 coaxial arrangements also be that electromagnetic force drives.Described clutch at a slow speed 25 places on the central shaft 28 in inverted heddle box 23 outsides, with warp-feeding and reeling belt wheel 27 adjacent putting.

When normally weaving, the motion of main transmission enters inverted heddle box 23 by belt wheel 22 inputs, Yi Bian by seeking comprehensive clutch 24 central shaft 28 is passed in motion, passes to vertical shaft box 21 then; Another side is directly passed to warp-feeding and reeling belt wheel 27.During automatic latitude seeking, this device with motor by a reduction box and pair of sprocket, through clutch 25 at a slow speed central shaft 28 is passed in motion again, pass to vertical shaft box 21 then; Another side is directly passed to warp-feeding and reeling belt wheel; Also pass to wefting insertion and beat up in addition moving through main motion input belt wheel.
