Abstract

The utility model discloses a heavy type jacquard head, belongs to parts for textile machinery, and particularly relates to the technical field of design and manufacture of heavy type jacquard heads. The heavy type jacquard head adopts the structure that a push-and-pull type heald-lifting electromagnet is arranged at the upper part of a body; a heald lifting rope is arranged at the lower part of electromagnet; and a heald-lifting spring is arranged under the heald-lifting rope. The heavy type jacquard head is used by being mounted at the uppermost part of a textile machine. A complete jacquard head is formed by a plurality of groups of heavy type jacquard heads with the same structures. When the electromagnet is powered-on, a pull rod in the middle of the electromagnet moves upwards and drives the heald-lifting rope to pull a warp to move upwards and stop in an upper position, and when each electromagnet is cut off, the warp is kept to be in a lower position. When the electromagnets in different groups are powered-on or cut off, each warp is in an upper position state or in a lower position state in one weaving period, opening of the warps in a weaving process is finished, and a work process that a conventional jacquard head drives a griffe to reciprocate up and down by means of mechanical transmission so as to further drive a hooking sheet to pull a warp which penetrates through a heald to move up and down, and whether the hooking sheet stops in an upper position or in a lower position is controlled in an auxiliary manner by an electromagnet is omitted. Therefore, a mechanical structure is simplified, the manufacture cost is reduced, and noise is reduced to a large extent.

Description

Heavy jacquard weave tap

Technical field

The utility model belongs to the textile machinery parts, is specially the design of a kind of heavy jacquard weave tap and manufacturing technology field.

Background technology

At present, employed heavy jacquard weave tap adopts electromagnet Aided Machine transmission working method to realize the opening of warp more on textile machine.Duty, the drop-down spring of shedding remains heald and is in downward pulling force, four connecting rod eccentric blocks promote to griffe to pump, griffing to drive the hook sheet pumps, when griffing to move to upper, keep the hook sheet upper, the electromagnet no power, the hook sheet is hooked on upper by self strain, the hook sheet drives the warp that passes heald and is parked in upper.When griffing to move to upper, electromagnet energising after hook flat spring sheet is held the hook sheet and breaks off relations by electromagnet, moves downward with griffing, and the warp that passes heald that alternately moves up and down to drive by the hook sheet alternately moves up and down and then drives warp the next.By alternately moving up and down of warp, realize the opening of warp thread.This complex structure, mechanical shock is big, and noise is big.Owing to complex structure, noise is very big during work, influences the healthy of operator in addition.Also increased operation easier.

Summary of the invention

At above-mentioned situation, the purpose of this utility model provides a kind of simple in structure, heavy jacquard weave tap that noise is little, solves the problem that existing product exists.

The utility model is to address the above problem the technical scheme of taking to be; In upper part of body one plug-type shedding electromagnet is arranged, have lifting-cord in the bottom of electromagnet, below lifting-cord, have the shedding spring.Warp passes the warp hole of lifting-cord during use.Use of the present utility model is the topmost position that it is installed in weaving loom.Form complete tap by many groups of such structural members, control warp and move up and down, realize shedding.Warp forms initially through line position the next, during work, when electromagnet is switched on because of the downward pulling force of shedding spring, pull bar in the middle of the electromagnet is operation upwards, drive lifting-cord pulling warp and move upward and be parked in upperly, during the electromagnet no power, warp remains on the next.To on the same group magnet switching electricity not, realize every warp the next state on a weave cycle, finish the weaving process shedding.The utility model moves up and down by shedding electromagnet and shedding spring drive warp exactly, the work of direct pull warp, having saved traditional jacquard weave tap relies on the machine driving drive to griffe to pump, and then drive the pulling of hook sheet and pass the warp of heald and move up and down, and be parked in upper or the next by the auxiliary control of electromagnet hook sheet.Simplify mechanical structure like this, reduced manufacturing cost, reduced noise again to a great extent.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further, in upper part of body one plug-type shedding electromagnet 1 is arranged, have lifting-cord 2 in the bottom of electromagnet, below lifting-cord, have shedding spring 4.Warp 3 passes the warp hole of lifting-cord during use.

Claims

1. heavy jacquard weave tap is characterized in that; In upper part of body one plug-type shedding electromagnet (1) is arranged, have lifting-cord (2) in the bottom of electromagnet, below lifting-cord, have shedding spring (4).
