Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, a fixed connection, an integral connection, or a detachable connection; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention in specific situations.

The structure of the electronically driven valve for a jacquard machine according to the present embodiment is shown in fig. 1 and 2, and includes a pair of metal hooks 2 installed back to back, the upper ends of the metal hooks 2 are connected in a hinged manner, and a spring 3 is installed between the lower ends of the pair of metal hooks. A pair of upper rope hooks 1 are mounted on the outer sides of the pair of metal hooks 2, the upper rope hooks 1 are structurally shown in fig. 3 and comprise a body 11, a hook portion 12 interacting with the metal hooks is arranged at the upper end of the body 11, an elastic arm 13 facing one side of the metal hooks 2 is arranged at a position, close to the hook portion 12, on the body 11, one end of the elastic arm 13 is fixedly connected with the body and is obliquely arranged relative to the body, the other end of the elastic arm is opened towards one side of the metal hooks 2, the free end of the elastic arm 13 faces one side of the hook portion, and a spacing groove 14 is formed between the elastic arm and the body 11.

The jacquard electronic driving valve with the structure has the advantages that in the working state, the upper rope hook can do high-speed reciprocating motion relative to the metal hook along the vertical direction, the free end of the elastic arm shown in fig. 3 can rub with the metal hook towards the part B on one side of the metal hook, the part B can be naturally worn after working for 4-5 years due to the fact that the upper rope hook is made of high-elasticity self-lubricating materials, and control precision of the electronic driving valve can be reduced or even the electronic driving valve can be disabled after the part B is worn.

As a maximum improvement of this embodiment, as shown in fig. 4-7, a receiving groove is preset in the spacing groove 14 for receiving the inserted compensating bar 10.

In a first embodiment of this embodiment, as shown in fig. 4, the first receiving groove 15 is substantially arc-shaped and is used for receiving a cylindrical compensating bar.

Preferably, in a second embodiment of the present invention, as shown in fig. 6, the second receiving groove 16 is substantially rectangular in shape and is used for receiving a compensating bar stock having a rectangular cross section. It should be noted that, the cross section of the compensating bar may be any polygon, and only the shape of the matching accommodating groove needs to be preset.

In the embodiment shown in fig. 4 and 6, when the electronically-driven valve operates for a long time and the B portion of the free end of the elastic arm 13 is worn to cause a decrease in control accuracy, as shown in fig. 5, an adaptive compensating bar 10 may be inserted into the accommodating groove to drive the elastic arm to expand outward to compensate for the worn position.

After the compensation bar is inserted, the rope-feeding hook recovers the normal use function and can be used for a long time, and the service life of parts and the whole is prolonged at the lowest cost under the condition of not changing a wear part.

Preferably, in a third embodiment of the present invention, as shown in fig. 7, the third receiving groove 17 has a multi-stage structure, and in the present embodiment, the third receiving groove includes a first-stage receiving groove 171 and a second-stage receiving groove 172 with different specifications. When the elastic arm is worn and needs to be compensated, the compensation bar can be inserted into the first-stage accommodation groove 171 to compensate the worn position. The rope hook that goes up through the compensation in the use, can be continued wearing and tearing, after the wearing and tearing volume influences normal use, in this embodiment mode, can pull out the compensation bar by in first order storage tank 171, insert in second order storage tank 172, because the expanded range of elastic arm is bigger after the compensation bar inserts second order storage tank 172, so, can carry out wearing and tearing position compensation once more.

The abrasion loss of the part B is usually 0.05mm of annual abrasion, and when the abrasion loss reaches 0.2mm, the electronic control valve goes wrong, so that a defective woven fabric is produced, and therefore, the abrasion condition of the part B of the rope-feeding hook needs to be checked after working for a certain period of time, for example, 2-3 years. Once the abrasion loss is close to 2mm, the abrasion compensation method of the embodiment can be used for abrasion compensation, the effect of compensating for 0.25mm every time can be designed, and the method can be continuously used for 3-5 years.

In the third embodiment, two-stage compensation is designed, the compensation can be carried out for 3-5 years, the service life of the wear part is further prolonged by arranging the two-pole accommodating groove, the saved cost is more, and the utilization rate of the wear part is higher. Of course, it is also possible to design more stages of compensation, for example inserting larger gauge compensating bars.

The service life of the jacquard is usually about 20 years, and in the life cycle of the jacquard, the number of the rope-feeding hooks of each device can reach 6000-40000 due to the huge number of the rope-feeding hooks, and the cost is saved considerably when the number of the rope-feeding hooks is reduced once.

In addition, the compensation mode of this application can be under the condition of not tearing open the machine, inserts the compensation bar, and the operation of tearing open when changing relatively, the cycle is obviously shorter, and can not cause the harm to other parts, can not cause the influence to the precision of equipment, and is also littleer to the loss that the shut down caused.

Preferably, in this embodiment, the accommodating groove is disposed at a groove bottom position close to the spacing groove 14. The purpose that so sets up lies in, is convenient for compensate the position of bar and prescribes a limit to, simultaneously, can guarantee the deflection of elastic arm to ensure the normal operating of electronically driven valve.

Preferably, in this embodiment, the accommodating groove is disposed on the body 11 opposite to the elastic arm 13. The purpose of so setting up is, the structural strength and the deformation stability of guarantee elastic arm.

In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
