Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Example 1

The present embodiment relates to a self-running shuttle box in a flat knitting machine.

As shown in fig. 1 and 2, the self-running shuttle box includes a basic shuttle box unit and a spring 2 and a pressing plate 3 a. The basic shuttle box unit is mainly composed of a shuttle box body 11, a yarn feeder rod 12 and a yarn feeder 13, and in addition, has some conventional components such as: the roller 16 arranged on the shuttle box body 11 is rotated to reduce friction when the self-running shuttle box moves transversely (in the direction of an arrow in the figure); an upper magnetic coil 14 and a lower magnetic coil 15 for guiding knitting yarns are provided on the shuttle box body 11 and the nozzle bar 12, respectively.

The present invention provides a new shuttle box unit different from the basic shuttle box unit by arranging the nozzle rod 12 of the basic shuttle box unit on the shuttle box body 11 in a way that it can move up and down and arranging the spring 2 between the shuttle box body 11 and the nozzle rod 12, and is named as a first shuttle box unit 1a in the present invention.

The up-and-down movable connection of the nozzle rod 12 and the shuttle box body 11 in the first shuttle box unit 1a of the present embodiment is designed such that: the yarn nozzle rod 12 is provided with a waist-shaped hole 125, the center of the lower part of the shuttle box is provided with two mounting screw holes, and two corresponding bolts 126 matched with the mounting screw holes penetrate through the waist-shaped hole 125 on the yarn nozzle rod and are screwed in the two mounting screw holes on the shuttle box, so that the yarn nozzle rod 12 moves up and down relative to the bolts 126 through the waist-shaped hole 125, and the arrangement of the yarn nozzle rod relative to the shuttle box body 11 in a vertically movable manner is realized. The yarn feeder rod 12 and the yarn feeder 13 are connected through a bolt-nut connecting piece, the yarn feeder 13 is connected to the lower end of the yarn feeder rod 12 through a waist-shaped hole 131, and the installation height of the yarn feeder 13 can be adjusted through the waist-shaped hole 131.

In order to facilitate the first shuttle box unit 1a to be matched with the pressing plate, a transverse through groove through which the pressing plate 3a can transversely pass is arranged above the shuttle box body 11, meanwhile, in order to enable the yarn mouth rod 12 to be well supported on the spring 2, the upper end of the yarn mouth rod 12 is provided with a limiting lug 120 protruding outwards, the protruding direction faces one side of the shuttle box body 11, the upper end of the yarn mouth rod extends into the transverse through groove 111, the limiting lug 120 is positioned in the transverse through groove 111, the upper end of the spring 2 is abutted against the lower end of the limiting lug, and the lower end of the spring 2 is abutted against the lower groove wall of the transverse through groove 111.

The pressing plate 3a in the self-running shuttle box can be transversely arranged on one side of the box body of the shuttle box, and the linear transverse movement of the pressing plate is realized by the guide constraint of the corresponding guide rail. The lower end of the presser plate 3a is provided with pressing surfaces 31 of unequal heights which are symmetrically arranged, and the heights of the pressing surfaces 31 acting on the yarn mouth bars 12 are changed by the lateral movement of the presser plate 3a relative to the shuttle box body 11, thereby forming different pressing depths (namely, elastic deformation amounts of springs).

The yarn feeder rod in this embodiment is connected to the upper end of the spring 2, and when the spring 2 is not pressed and does not elastically deform, the yarn feeder 13 connected to the lower end of the yarn feeder rod 12 is stably maintained at a height position corresponding to the initial state of the spring 2. The spring 2 can generate corresponding elastic deformation only under the action of the pressing plate 3a, and the yarn nozzle rod drives the yarn nozzle to do corresponding lifting movement during the elastic deformation, so that the height position of the yarn nozzle is changed. The initial height position of the yarn feeder 13 without elastic deformation is adapted to the corresponding height position of the yarn feeder without lifting during the knitting process, such as the corresponding height position of common knitting, intarsia knitting and the like. In the knitting process without adjusting the height position of the yarn feeder, the pressing plate moves out of one side of the shuttle box body transversely and is separated from the shuttle box body and the yarn feeder rod 12, the yarn feeder rod 12 moves transversely along with the shuttle box body 11 at the height corresponding to the initial state of the spring to feed the yarn feeder, and the pressing plate 3a is not needed to maintain the corresponding height position of the yarn feeder 13. Only when the height position of the yarn nozzle is required to be adjusted in the weaving process, the pressing plate 3a transversely moves to one side in the shuttle box body 11 and acts on the yarn nozzle rod 12 to be combined with the yarn nozzle rod 12, so that the height position of the yarn nozzle 13 is changed, and the pressing plate 3a and the first shuttle box unit 1a corresponding to the yarn nozzle 13 synchronously move, so that the yarn nozzle is kept at the adjusted height position.

Example 2

This embodiment relates to another self-running shuttle box in a flat knitting machine.

As shown in fig. 3 and 4, the self-running shuttle box of the present embodiment also includes a basic shuttle box unit and spring 2 and a pressing plate 3 b. The structure of the pressing plate 3b is the same as that of the pressing plate 3a of the embodiment 1, and the first shuttle box unit 1b is basically the same as that of the embodiment 1, except that the yarn feeder rod 12 of the first shuttle box unit 1b of the embodiment is a combined rod member, and mainly comprises a yarn feeder base rod 121 and an adjusting rod 122. The yarn nozzle base rod 121 is a conventional yarn nozzle rod fixed on the shuttle box body, and has two mounting holes 1211 arranged at the upper end along the length direction for connecting the shuttle box body 11, and two first connecting holes 1212 arranged at the lower end along the length direction. In this embodiment, the existing yarn feeder base rod 121 is combined with the newly designed adjusting rod 122, the limiting protrusion 120 is disposed at the upper end of the adjusting rod 122, two second connecting holes 1221 adapted to the hole pitch of the first connecting hole 1212 are disposed at the lower end of the adjusting rod 122 along the length direction, and a first waist-shaped hole 1222 is disposed between the limiting protrusion 120 and the second connecting hole of the adjusting rod 122. When the two rods are combined, the adjusting rod 122 is attached to one side of the inner side surface of the yarn nozzle base rod, namely, one side corresponding to the shuttle box body, the upper end of the adjusting rod extends out of the upper end of the yarn nozzle base rod 121, the second connecting hole 1221 on the adjusting rod is concentrically communicated with the first connecting hole 1212 on the yarn nozzle base rod, the first waist-shaped hole 1222 on the adjusting rod is aligned and communicated with the mounting hole 1211 on the yarn nozzle base rod, the two bolts 126 penetrate through the two mounting holes 1211 on the yarn nozzle base rod and the first waist-shaped hole 1222 on the adjusting rod and are screwed into the corresponding two mounting screw holes on the shuttle box body, and the yarn nozzle rod 12 formed by combination moves up and down relative to the bolt 126 through the first waist-shaped hole 1222. The yarn feeder 13 as in embodiment 1 is adopted to be attached to the outer side surface of the yarn feeder base rod 121, and the bolt of the bolt-nut connecting piece 127 passes through the first connecting hole on the yarn feeder base rod, the second connecting hole on the adjusting rod and the waist-shaped hole 131 on the yarn feeder and is screwed with the nut to connect the three together, wherein the yarn feeder base rod and the adjusting rod are connected to form a combined yarn feeder rod 12, and the yarn feeder 13 is connected to the lower end of the yarn feeder rod 12.

In the embodiment, the yarn nozzle rod 12 is combined with the existing yarn nozzle base rod 121 fixed on the shuttle box body through the adjusting rod 122, so that the originally fixed yarn nozzle rod can be vertically moved on the shuttle box body, and the spring 2 is conveniently placed.

Example 3

The embodiment relates to a self-running shuttle box mechanism in a flat knitting machine.

As shown in fig. 5, the self-running shuttle box mechanism of the present embodiment is composed of at least two first shuttle box units 1a, 1b, two pressing plates 3a, 3b, shuttle box driving units 4a, 4b that drive the two first shuttle box units, respectively, and two pressing plate driving units 5a, 5b that drive the two pressing plates 3a, 3b, respectively. The first shuttle box units 1a, 1b and the presser plates 3a, 3b are each traversable along a transversely disposed shuttle bar 6 erected on a frame 9 of the flat knitting machine. The two first shuttle box units 1a, 1b in this embodiment are the first shuttle box units described in the above-described embodiments 1 and 2, respectively. The shuttle box driving units 4a and 4b and the pressing plate driving units 5a and 5b are synchronous belts and wheel driving mechanisms directly driven by motors and respectively act on driving the first shuttle box units 1a and 1b and the pressing plates 3a and 3 b. Wherein: the shuttle box driving units are composed of corresponding timing belts 43a, 43b connected to the corresponding shuttle box cases 11 in the first shuttle box unit, two corresponding synchronizing wheels 41, 42 engaged with the timing belts, and corresponding motors 44a, 44b connected to the synchronizing wheels 41, 42. The two pressing plate driving units 5a, 5b are composed of corresponding timing belts 53a, 53b connected with the corresponding pressing plates, two corresponding timing wheels 51, 52 engaged with the timing belts, and corresponding motors 54a, 54b connected with the timing wheels 51, 52. The shuttle box cases 11 and the corresponding pressing plates 3a and 3b in the two self-running shuttle boxes respectively move along the tracks arranged on the shuttle bar 6, the two corresponding motors 44a and 44b in the two shuttle box driving units 4a and 4b and the two corresponding motors 54a and 54b in the two pressing plate driving units 5a and 5b are respectively arranged on the frames 9 corresponding to the two ends of the shuttle bar, and the corresponding synchronous belts 43 and 53 are arranged along the parallel direction of the shuttle bar in a vertically staggered way.

In the weaving process, the height position of the yarn nozzle needs to be adjusted in the weaving process due to the requirement of weaving organization, and fig. 5 illustrates two first shuttle box units 1a and 1b adopted in weft insertion weaving, wherein the yarn nozzle 13 in the first shuttle box unit 1a needs to do lifting action, and the height position of the first shuttle box unit 1b does not change in the weaving process.

With the first shuttle box unit 1a, the corresponding presser plate 3a acts on the yarn mouth bar 12 thereon by the lateral movement with respect to the first shuttle box unit 1a (yarn mouth 13) and presses the upper end of the yarn mouth bar 12 against the lowest position of the presser plate pressing surface 31 to fit to the height position required for weft insertion knitting. The pressing plate driving unit 5a and the shuttle box driving unit 4a work simultaneously to respectively drive the first shuttle box unit 1a and the pressing plate 3a to move transversely, and the pressing plate 3a keeps the adjusted yarn nozzle height through the synchronous movement with the first shuttle box unit 1 a.

For the first shuttle box unit 1b, since the height position does not change during the whole knitting process, no pressing plate action is required, as long as the yarn mouth 13 of the first shuttle box unit 1b is adapted to the required height position by the adjustment of the upper waist-shaped hole 131 thereof (see embodiment 2 and fig. 3) when being installed. If the first shuttle box unit 1b is combined with the corresponding pressing plate 3b in the initial state, the pressing plate driving mechanism 5b separates the first shuttle box unit 1b, the first shuttle box unit 1b only drives the corresponding shuttle box driving mechanism 4b to move transversely along the shuttle bar, the corresponding yarn feeding action with unchanged height position is completed, the corresponding pressing plate driving mechanism 5b does not work at this time, and the corresponding pressing plate driving mechanism 5b does not need to run to and fro and empty with the shuttle box driving mechanism 4b driving the first shuttle box unit 1 b.

As shown in fig. 6, in the case of the inlay knitting performed by the shuttle box mechanism according to the present embodiment, similarly to the above-mentioned inlay knitting, the height position of the first shuttle box unit 1b is not changed during the knitting process and is already at the desired height position, and the yarn nozzle 13 in the first shuttle box unit 1a needs to be moved up and down, and at this time, the pressing plate 3a is applied to the yarn nozzle rod 12 by the traverse motion, and the upper end of the yarn nozzle rod 12 is pressed against the highest position of the pressing surface 31 of the pressing plate, so that the yarn nozzle height 13 is adapted to the height position required for inlay knitting. The pressing plate driving unit 5a and the shuttle box driving unit 4a work simultaneously to respectively drive the first shuttle box unit 1a and the pressing plate 3a to move transversely, and the pressing plate 3a keeps the adjusted yarn nozzle height through the synchronous movement with the first shuttle box unit 1 a. The first shuttle box unit 1b only needs to be driven by the shuttle box driving unit 4b in the whole weaving process, and the corresponding pressure plate 3b and the pressure plate driving unit 5b do not need to work.

As shown in fig. 7, in the self-running shuttle box mechanism of the present embodiment, the normal knitting can be performed by one of the first shuttle box units 1b (the first shuttle box unit 1a is not placed on the shuttle bar side), and at this time, the corresponding presser plate 3b is separated from the first shuttle box unit 1b, the nozzle rod 12 which does not act on the first shuttle box unit 1b is adjusted to the height position required for the normal knitting when the nozzle is mounted, and the first shuttle box unit 1b is driven to perform the yarn feeding operation required for the normal knitting only by the shuttle box driving unit 4b during the self-running process, and the corresponding presser plate 3b and the presser plate driving unit 5b are not required to control the height of the nozzle, and the movement is synchronized with the first shuttle box unit 1b to maintain the height, thereby reducing the loss of the energy and the working life of the corresponding motor in the presser plate driving unit 5 b.

As shown in fig. 8, the self-running shuttle box mechanism of the present embodiment is additionally provided with two second shuttle box units 8a and 8b in addition to the above-described embodiment 3. The driving mechanism of the present embodiment is composed of the shuttle box driving units 4a, 4b that drive the two first shuttle box units 1a, 1b, respectively, and the presser plate driving units 5a, 5b that drive the two presser plates 3a, 3b, respectively, as in embodiment 3, in spite of the addition of the second shuttle box unit. The invention can utilize the idle pressing plate driving unit for driving the yarn nozzle of the first shuttle box unit to lift to drive the second shuttle box unit 8 to work (in the actual weaving, the weaving ratio of the yarn nozzle needing to lift is not high, and the corresponding pressing plate driving unit is often idle).

Referring to fig. 9 and 10, the second shuttle box unit 8a, 8b of the present embodiment is mainly composed of a shuttle box body 81, a yarn feeder rod 82 and a yarn feeder 83, and further includes conventional components such as a roller 86, an upper magnetic coil 84 and a lower magnetic coil 85. The nozzle rod 82 is fixed to the shuttle box body 81. The shuttle box body 81 has basically the same structure as the shuttle box body 11 in the embodiment 1, a transverse through groove 811 capable of transversely passing through the pressing plate is arranged above the shuttle box body, and an insertion channel 812 communicated with the transverse through groove 811 is also arranged above the transverse through groove 811. And the upper end of the pressing plate is provided with an insertion notch 32 which is matched with the width of the insertion channel 812, as shown in fig. 11 and 12, and is also provided with an insertion block 88, the insertion channel 812 and the insertion notch 32 are inserted through the insertion block 88, so that the insertion block 88 connected to the shuttle box body 81 is inserted into the insertion notch 32 on the pressing plate, the second shuttle box unit and the corresponding pressing plate are detachably connected in an insertion manner, and the insertion channel 812 on the shuttle box body, the insertion notch 32 on the pressing plate and the insertion block 88 form a detachable connection assembly.

Fig. 8 shows the driving of the yarn feeder in the case of the intarsia knitting from the shuttle box mechanism in the present embodiment, and the yarn feeder for intarsia knitting does not need to be lifted, but the number of yarn feeders needs to be large because the yarn feeder corresponds to the number of colors of the color yarn required for intarsia. In the present embodiment, two second shuttle box units 8a and 8b and two first shuttle box units 1a and 1b are adopted to weave four color yarns, at this time, the two pressing plates 3a and 3b and the two pressing plate driving units 5a and 5b corresponding to the two first shuttle box units 1a and 1b are not needed any more, and the two second shuttle box units 8a and 8b are driven by the two idle pressing plates 3a and 3b and the pressing plate driving units 5a and 5 b. Two pressing plates 3a and 3b are enabled to transversely move to one side corresponding to two second shuttle box units 8a and 8b, the corresponding inserting blocks 88 are inserted into the inserting channels 812 on the corresponding shuttle box body and the inserting gaps 32 on the corresponding pressing plates to detachably connect the second shuttle box units with the corresponding pressing plates in an inserting mode, the two pressing plates are respectively used for driving the corresponding second shuttle box units to transversely move along the shuttle bars through the inserting blocks 88, corresponding yarn feeding actions are completed, only the pressing plate driving units work in the process of self-running yarn feeding of the second shuttle box units, the pressing plate driving units can be used for driving yarn mouths which are not required to be adjusted in height in a lifting mode when the pressing plate driving units are not used for adjusting the lifting driving of the yarn mouths, therefore, the utilization rate of idle pressing plate driving mechanisms can be improved, the motor workload of the pressing plate driving units and the shuttle box driving units is balanced, and the utilization rate of corresponding motors of the pressing plate driving mechanisms is improved.
