Description

The energy-saving efficient special-shaped reed slice

Technical field

The utility model relates to technical field of textile machine, and is special relevant with a kind of energy-saving efficient special-shaped reed slice.

Background technology

Profiled Reed is the air-jet loom reed that carries out the relay wefting insertion with pilot jet, has the function that determines the warp thread arrangement position and weft yarn is thrown into fell.

Original special-shaped reed slice as shown in Figure 1, the reed wire body comprises upper end 10, lower end 20, the reed wire body back 30 that upper end 10, lower end 20 connect is flat, and hump 40 and lower hump 50 on the front of reed wire body has form an airslide 60 between upper hump 40 and the lower hump 50.During wefting insertion, with the air stream junction and become a branch of synthetic air-flow that meets the wefting insertion technological requirement, weft yarn is along with air-flow advances along airslide 60 in the main jet air-flow on the loom and the airslide 60 of secondary air on the special-shaped reed slice body.When beating up, beat up a little in the bottom of airslide 60.

Because the speed of a motor vehicle of air-jet loom is high, is generally about 600r/min, whole reed is about 600 times/min to yarn reciprocating friction and strike, and this has caused heavy wear for undoubtedly the reed wire body, and anti-impact force is weak.The intensity of original reed wire body own is not high, be loaded on after the reed plate, the reed plate rotates and beats up, intensity is not high directly to cause beating up service life of reed, existing reed can only maintain about one month, and reed wire just needs to change, and replacement frequency is high, have a strong impact on the air-jet loom operating efficiency, virtually increased cost.

Given this, the inventor designs a kind of energy-saving efficient special-shaped reed slice, and this case produces thus.

The utility model content

Main purpose of the present utility model provides a kind of energy-saving efficient special-shaped reed slice, has high-strength impact-resistant power, and stability is strong, and is wear-resistant, has significantly prolonged service life, and has fallen the saving material, reduces cost.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

The energy-saving efficient special-shaped reed slice comprises the reed wire body, and the reed wire body comprises upper end, lower end; The front of reed wire body has upper hump, lower hump, forms up and down airslide between the hump; At the back side of reed wire body, hump forms the arc section of an outside projection to the position of lower hump on the aligning.

Described arc section comprises that the multistage lines form, forming Radius at the stressed weak center of airslide line is the 8mm circular arc, this circular arc outermost point outwards departs from reed wire body back side straight line 1.5mm, the starting point of hump is the tangent line A of a circular arc on the straight line correspondence of the reed wire body back side, the starting point of hump is the tangent line B of a circular arc under the straight line correspondence of the reed wire body back side, tangent line A, circular arc, the described arc of the common composition of tangent line B section.

The upper cell wall that described airslide connects upper hump is level, and the lower cell wall and the horizontal line that connect lower hump form 12 ° of angles, so that airslide is inner small and outside big structure.

The most inboard groove of described airslide directly is 5.5mm, and the center line at the central point place of circular arc departs from cell wall 3mm.

After adopting such scheme, the utlity model has many beneficial effects:

The utility model Main Analysis the weakest stress point on the reed wire body, and set up an arc section at the reed wire body back side on this basis, consolidated the intensity of reed wire body, ABRASION RESISTANCE and impact strength have been improved, improve the resistance to overturning of reed, prolong the service life of reed wire body, guarantee reed wire body service life more than 6 months, to be at least 6 times of original service life.Because the intensity of reed wire body improves, can correspondingly reduce the thickness of reed wire body when producing Profiled Reed, the weight saving of reed wire body, the reed wire body can reduce by 15%～20% material, has reduced material cost.Because the reed wire body thickness reduces, and has increased the space rate of reed, reduce the wearing and tearing between warp thread and the reed wire body, prevention cracked ends phenomenon.

Description of drawings

Fig. 1 is the structural representation of reed wire body in the prior art;

Fig. 2 is the structural representation of the utility model preferred embodiment.

The specific embodiment

By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.

The energy-saving efficient special-shaped reed slice comprises reed wire body 1, main crucial exactly the improving in shape at reed wire body 1 of the utility model.

Reed wire body 1 comprises upper end 2, lower end 3.Upper end 2, lower end 3 are used for the solid and reed beam of dress.The front of reed wire body 1 has upper hump 4, lower hump 5, forms an airslide 6 between upper hump 4, the lower hump 5.Airslide 6 comprises the upper cell wall 61 that is connected with upper hump 4 and the lower cell wall 62 that is connected with lower hump 5 in the present embodiment, and upper cell wall 61 is level, and lower cell wall 62 forms 12 ° angle with horizontal line, and is inner small and outside big state.The most inboard groove directly is 5.5mm.The structure of this airslide 6 is to cooperate the angle of auxiliary nozzle and decide, and the optimally interleaved point that interweaves in order to reach warp thread and weft yarn is avoided cracked ends, the unsettled problem of air-flow.

Force analysis through actual reed wire body 1, in airslide 6, depart from cell wall 3mm place and be the most weak line of force H that is subjected to, do a circular arc R, the center of circle is in this most weak being subjected on the line of force H, it is 1.5mm that the outermost point of circular arc R departs from reed wire body 1 back side straight line T, then overleaf on the straight line T aligning starting point place of hump 4 begin to be the tangent line A of a circular arc R, the starting point place of hump 5 began to be the tangent line B of a circular arc R under straight line T aimed at equally overleaf, by tangent line A, circular arc R and tangent line B, the continuous sealing line segment that the three forms forms the outline line of the arc section 8 in the utility model.Because the outer most bits in the arc section 8 is arc structure, the good hand touch of arc section 8, easily processing, warp thread is difficult for being worn, not cracked ends.

Key point of the present utility model analyzes its weakest line of force that is subjected at original special-shaped reed slice body, and its intensity is strengthened in this position, improves the impact strength when beating up.Strengthen ABRASION RESISTANCE, so that the reed wire body significantly prolongs service life, can reduce the thickness of reed wire body 1 simultaneously, save material.Because reed wire body 1 thickness reduces, and has so just improved the space rate of reed in assembling, effectively prevent the warp thread wearing and tearing, prevention cracked ends phenomenon, the operating efficiency of raising air-jet loom.

Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
