Description

Inkle loom heald frame extension spring device

The utility model is a kind of inkle loom heald frame extension spring device, it is a kind of extension spring device that resets in order to the pulling heald frame in the inkle loom that is arranged on, by appropriate structural arrangements, the steadiness of uniform pulling force and structure is provided, and can be improved whole service life.

As everyone knows, the kind of inkle loom is quite various, but no matter which kind of pattern it is, it all must adopt " heald frame " to control the action of its warp, and on most inkle loom structural arrangements all only to the operation sheet of heald frame to the application of force, and reset with spring or associated mechanisms.After computer-controlled inkle loom was finished by development in recent years, the inkle loom that each manufacturer produced developed towards the mode of high speed operation especially, and in order moment to make heald frame reach the location in operation, its device that resets promptly seems extremely important.

In the existing inkle loom, having a kind of is to utilize " extension spring device " to carry out resetting of heald frame, its structure such as Fig. 6-shown in Figure 8, in this extension spring device 90, be to control a heald frame with two groups of extension springs 92 to reset, each group extension spring 92 is the elastic materials that are square by four sections, the elastic parts made of high-tension rubber for example, be installed with a swing pipe 94 respectively two groups of extension spring 92 upper ends, and can fixedly be suspended from the frame by lifting hole(eyelet) 940, lower end two groups of extension springs 92 then is respectively equipped with connection tube 96, and the below of this two connection tube 96 is connected with cohesive frame 98, and connects heald frame by this cohesive frame 98.Its major defect is:

1, in the following discovery of the check and analysis of precision, also perfect inadequately on its structural design, because the mode that extension spring 92 combines with swing pipe 94 and connection tube 96, be that extension spring 92 upper ends are penetrated in swing pipe 94 lower ends, extension spring 92 lower ends are penetrated in connection tube 96 upper ends, and combine with gummed or alternate manner, flatten around the upper end of swing pipe 94 lower ends and connection tube 96 then, provide extension spring 92 to grip strength.The extension spring device of this kind pattern in use the problem of normal generation promptly be its extension spring 92 fractures, and the position of the most normal generation fracture is to be its upper end and the joining place of swing pipe 94 or the joining place of lower end and connection tube 96, trace it to its cause and promptly be the undesirable of its fixed form, because come clamping in conjunction with the flexible extension spring 92 of tool the mode that swing pipe 94 or connection tube 96 are flattened, it must reach firm in conjunction with effect, can cause compressing improperly and distortion to extension spring 92 simultaneously, have influence on its due elasticity, cause the material at the position that suffers oppression impaired even;

2, it is shared that the extension spring device of this kind of discovery pattern is adopted two groups of extension springs 92 in experiment, though the pulling force of two groups of extension springs 92 gathers the back to the heald frame application of force by cohesive frame 98, but when reality is used, these two groups of extension springs 92 are difficult for the pulling force that provides equal, that is two groups of extension springs 92 are when stressed, the length of its elongation is also inequality, so can cause stressed one group of bigger extension spring 92 more impaired, in use can make simultaneously cohesive frame 98 produce the phenomenon that swings, this phenomenon is more obvious when running up, and this also is existing extension spring device not most perfect problem that causes on structural design.

3, careful inadequately when regular meeting finds because of the assembler assembling in practical operation again; and can be because the inclination or the skew of swing pipe 94 or connection tube 96; make extension spring 92 produce distortion; make extension spring 92 phenomenon that twists when the assembling because of the carelessness of assembler even; it will inevitably cause the unbalance stress of extension spring device, and can have influence on the service life of extension spring device.Seriously influence causing the service life of extension spring 92; because in case arbitrary elastic parts in one group of extension spring 92 ruptures; promptly must shut down and change; and each replacing must be two groups and upgrade simultaneously; cause the waste of material, some production firm causes interruption in the operation for fear of shutdown, even when each periodic maintenance; be about to all extension spring devices and upgrade in the lump, it has considerable influence to production cost.

At above-mentioned defective, the inventor carries out research and analysis, after constantly testing and attempting, creates the technical solution of the utility model finally.

Main purpose of the present utility model is: a kind of inkle loom heald frame extension spring device is provided, it mainly is the extension spring that is provided with full wafer shape structure between upper and lower fixing plate, this extension spring simultaneously is to be with upper and lower fixing plate to be wholely set, and can offer the slit of multiple tracks longitudinally according to need, overcome the drawback of prior art, reach that structural stability is good, the purpose of uniform elastic and long service life.

The purpose of this utility model is achieved in that a kind of inkle loom heald frame extension spring device, includes heald frame and extension spring, and it is characterized in that: this extension spring is the sheet structure of elastic construction; Upper mounted plate is provided with lifting hole(eyelet) in the form of sheets on this upper mounted plate; Bottom plate is provided with the hook part at this bottom plate lower edge in the form of sheets; This extension spring and the upper and lower fixing plate structure that is combined into one that is formed in one.

Offer the slit of multiple tracks longitudinally in this extension spring.The upper and lower end in the slit of this extension spring is arc edge respectively.This upper mounted plate lower edge is bent to form a U-shaped limit, and is provided with a plurality of open-works in the bending place on this U-shaped limit.The edge of this each open-work is provided with the bluff piece of bending the upper mounted plate lower edge downwards.This bottom plate upper limb is bent to form a U-shaped limit, and is provided with a plurality of open-works in the bending place on this U-shaped limit.The edge of this each open-work is provided with the bluff piece of upwards bending the bottom plate upper limb.

Major advantage of the present utility model be have that structural stability is good, the effect of uniform elastic and long service life.
