Description

Small-volume suction structure of needle selection module of jacquard

Technical Field

The utility model belongs to the technical field of the jacquard machine technique and specifically relates to a little volume actuation structure of needle module is selected to jacquard machine.

Background

In the weaving technique of the jacquard, the larger the number of needles arranged in a unit area, the higher the definition of the woven fabric. However, the number of needles per unit area of the jacquard is basically determined by the size of the needle selecting assembly. At present, a rotating shaft is connected to the lower end of a moving iron of a needle selecting assembly, then the attraction surface of the moving iron is located above the rotating shaft, in addition, a pushing component is arranged on a vertical hook, and the moving iron is pushed towards the direction of an electromagnet in the lifting process of the vertical hook specially so as to be attracted by the electromagnet. Therefore, under normal conditions, the vertical hook and the moving iron are not positioned on the same vertical straight line, and the vertical hook and the moving iron are staggered, so that the whole size of the needle selection module is larger.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a little volume actuation structure of needle module is selected to jacquard machine in order to solve the not enough of above-mentioned technique, compact structure, whole size reduces relatively.

In order to achieve the above object, the utility model relates to a small volume suction structure of needle selection module for jacquard machine, which comprises an electromagnet, a movable iron and a vertical hook arranged on the same splint or bottom plate, wherein the movable iron is respectively arranged on two sides of the electromagnet, the upper end of the movable iron is connected on the splint or the bottom plate through a pin shaft, a first hook-shaped structure is arranged on the outer side surface of the lower end of the movable iron, the vertical hook is respectively and correspondingly arranged in a chute on the splint or the bottom plate below the movable iron, the upper end of the vertical hook is provided with a second hook-shaped structure matched with the first hook-shaped structure on the movable iron, the suction surface of the electromagnet is arranged in the middle of the movable iron, and a pressure spring is arranged between the; the moving iron below the attraction surface of the electromagnet bends inwards, and the first hook-shaped structure is positioned on the part bending inwards.

The needle selecting mechanism of the jacquard machine forms gaps between a bottom plate and a clamping plate and between the clamping plate and a cover plate, and the needle selecting modules are respectively arranged in the gaps, so that the needle selecting modules can be arranged on the clamping plate and can also be arranged on the cover plate. The upper end of the moving iron is rotatably connected with the clamping plate or the base plate through the pin shaft, the attraction surface of the electromagnet and the moving iron is positioned below, and metal particles generated by attraction collision of the electromagnet and the moving iron cannot fall into lubricating grease of the pin shaft in the normal working process, so that the moving iron and the pin shaft are small in abrasion. Meanwhile, the vertical hook below the first attraction surface is bent inwards, the first hook-shaped structure is positioned on the inward-bent part of the moving iron, so that the vertical hook can be arranged right below the moving iron, the vertical hook and the part of the moving iron which is not bent inwards are positioned at the same vertical position, the first hook-shaped structure and the second hook-shaped structure can be matched within the bending range of the moving iron, when the vertical hook continuously rises, the upper end of the vertical hook can be in contact with the bent position of the moving iron and is pushed inwards to be close to the attraction surface of the electromagnet, the attraction of the vertical hook is finally kept, and the vertical hook can normally fall. Therefore, the structure is more compact, the whole volume can be reduced, and the needle number of the jacquard is increased.

Because the vertical hook can contact and collide with the moving iron in the lifting process, in order to avoid rigid collision between the vertical hook and the moving iron, an elastic body is arranged at the upper end of the vertical hook. The elastomer can cushion the collision between carabiner and the moving iron, reduces the impact force, makes its operation more stable.

As optimization, the positioning tables on the two sides of the clamping plate or the bottom plate are positioned below the position of the pin shaft on the moving iron. Due to the existence of the pin shaft, the pin hole is required to be formed in the position of the moving iron, so that the width of the moving iron at the position is relatively large, the positioning table of the clamping plate or the bottom plate is arranged below the pin shaft, the width of the clamping plate can be reduced without increasing the width outside the pin shaft to form the positioning table, and the whole size is smaller.

The utility model provides a little volume actuation structure of needle module is selected to jacquard, it is through reasonable structural design, can make the structure between each part compacter, and the operation is reliable and stable, reduces the whole size of selecting the needle module.

The cross section area of a single needle of the mechanism is 0.6 times of that of the traditional product, and the jacquard high-end fabric with large needle number which cannot be woven in the prior art can be woven.
