Abstract

The utility model discloses a linkage structure of opening device and wefting insertion system, including the frame, be provided with the drive shaft in the frame, opening device includes the actuating lever, and the wefting insertion system includes the wefting insertion arm, is provided with two eccentric wheels in the drive shaft side by side, and the eccentric wheel is outer all fixed to be provided with the bearing, and actuating lever and wefting insertion arm all are fixed to be set up on the outer lane of bearing. The utility model has the advantages of it is following and effect: when the driving shaft is driven by the motor to rotate, the driving shaft can simultaneously drive the two eccentric wheels to move, and when the eccentric wheels move, the bearing on the outer side can drive the annular ring to respectively drive the driving rod and the weft insertion arm to swing, so that the opening device and the weft insertion system are driven simultaneously, on one hand, the occupation of the space on the rack can be reduced, and on the other hand, certain energy consumption can also be reduced.

Description

Linkage structure of shedding device and weft insertion system

Technical Field

The utility model relates to a rapier weaving machine technical field, in particular to linkage structure of opening device and wefting insertion system.

Background

The heald frame is an important part in the loom and is a frame with heald penetrating rods and driving parts connected via upper and lower transverse beams and left and right side rails. After the heald is arranged on the heald frame, the warps penetrating the heald are integrated, the heald frame moves up and down according to the program of the shedding device along with the movement of the heald lifting mechanism of the weaving machine, the warps are opened in layers, and weft yarns are shuttled among the warps to be interwoven into fabrics with different patterns.

Weft insertion is one of the main movements of a weaving machine, which introduces a weft thread from one side of the weaving machine into an open warp layer. The mechanism that performs this motion is called the "weft insertion mechanism".

In the rapier loom in the prior art, a driving rod of a heald frame opening device and a weft insertion arm of a weft insertion system are driven by adopting separate driving sources, so that different driving sources are required to be installed on the side surface of the rapier loom, on one hand, the space on the side surface of a rack is occupied, and on the other hand, part of extra energy consumption is also increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can reduce the space of frame side and occupy and reduce the heald frame opening device of energy consumption and the linkage structure of wefting insertion system.

The above technical purpose of the present invention can be achieved by the following technical solutions: the linkage structure of the opening device and the weft insertion system comprises a rack, wherein a driving shaft is arranged on the rack, the opening device comprises a driving rod, the weft insertion system comprises a weft insertion arm, two eccentric wheels are arranged on the driving shaft in parallel, bearings are fixedly arranged outside the eccentric wheels, and the driving rod and the weft insertion arm are fixedly arranged on outer rings of the bearings.

Further setting the following steps: an annular ring is sleeved on the outer ring of the bearing, the driving rod and the weft insertion arm are respectively fixed on the annular ring, and the annular ring and the outer ring of the bearing are fixed through screws.

Further setting the following steps: the annular ring is integrally provided with a convex block, and the driving rod and the weft insertion arm are both in threaded connection with the convex block.

Further setting the following steps: and the two sides of the bearing are both provided with limiting pieces, and the limiting pieces and the inner ring of the bearing are fixed through screws.

Further setting the following steps: the eccentric directions of the two eccentric wheels are opposite.

To sum up, the utility model discloses following beneficial effect has: when the driving shaft is driven by the motor to rotate, the driving shaft can simultaneously drive the two eccentric wheels to move, and when the eccentric wheels move, the bearing on the outer side can drive the annular ring to respectively drive the driving rod and the weft insertion arm to swing, so that the opening device and the weft insertion system are driven simultaneously, on one hand, the occupation of the space on the rack can be reduced, and on the other hand, certain energy consumption can also be reduced.

Drawings

Fig. 1 is a perspective view of a linkage structure.

In the figure: 1. a frame; 2. a drive shaft; 3. a drive rod; 4. a weft insertion arm; 5. an eccentric wheel; 6. a bearing; 7. an annular ring; 8. a bump; 9. a limiting sheet.

Detailed Description

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

Linkage structure of shedding device and wefting insertion system, including frame 1, be provided with drive shaft 2 on the frame 1, drive shaft 2 is rotated by motor drive. The shedding device comprises a driving rod 3, the weft insertion system comprises a weft insertion arm 4, and the driving rod 3 and the weft insertion arm 4 are respectively used for power input of the shedding device and the weft insertion system in the prior art.

Two parallel eccentric wheels 5 are arranged on the driving shaft 2 and positioned on the outer side of a side plate of the machine frame 1, and the eccentric directions of the eccentric wheels 5 are opposite. The eccentric wheel 5 is externally sleeved with a bearing 6, the outer rings of the bearing 6 are sleeved with annular rings 7, and the annular rings 7 are fixed on the outer rings of the bearing 6 through screws. A protruding block 8 with a circular section is integrally arranged on the annular ring 7, a threaded hole is formed in the top of the protruding block 8, and the driving rod 3 and the weft insertion arm 4 are fixed on the protruding block 8 in a threaded connection mode.

The two sides of the two bearings 6 are both fixedly provided with a round limiting piece 9, and the limiting piece 9 is fixed on the inner ring of the bearing 6. The limiting sheet 9 can prevent the rotating bearing 6 from being exposed, and the safety of workers is guaranteed.

When the driving shaft 2 is driven by the motor to rotate, the driving shaft can simultaneously drive the two eccentric wheels 5 to move, and when the eccentric wheels 5 move, the bearing 6 on the outer side can drive the annular ring 7 to respectively drive the driving rod 3 and the weft insertion arm 4 to swing, so that the shedding device and the weft insertion system are simultaneously driven, on one hand, the occupation of the space on the rack 1 can be reduced, and on the other hand, certain energy consumption can also be reduced.

The eccentric directions of the two eccentric wheels 5 are opposite, so that the force application of the driving shaft 2 is uniform, the loss caused by unidirectional stress is avoided, and the service life is prolonged.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
