Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water-jet loom, in particular to a water-blocking cover structure of water-jet loom. BACKGROUND

[0002] The water-jet loom is a shuttleless loom using water flow as weft leading medium, and through the water flow beam to generate friction traction on weft yarn, and the weft yarn is pulled through the shed. When the water flow pulls the weft yarn through the shed, the water flow will cause the warp yarn and fabric in the near area of the shed to be wet. In order to prevent water splashing, a water-blocking cover needs to be placed above the shed. The water-blocking cover in the prior art has the disadvantages of complex structure and large vibration. SUMMARY

[0003] In view of the deficiencies in the prior art, the main purpose of the present application is to provide a water-blocking cover structure of water-jet loom which is simple in structure, good in fixing effect and low in vibration.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a water-blocking cover structure of water-jet loom, comprising a water-blocking cover support plate, an intermediate arc-shaped ring, an end arc-shaped ring and a water-blocking cover. An arc-shaped installation groove is arranged on the water-blocking cover support plate. The intermediate arc-shaped ring and the end arc-shaped ring are arranged in the arc-shaped installation groove. The water-blocking cover comprises a cover body and a cylindrical connecting portion connected with the cover body. The opening size of the intermediate arc-shaped ring and the end arc-shaped ring is smaller than the diameter of the cylindrical connecting portion. The opening of the intermediate arc-shaped ring and the end arc-shaped ring is deformable, and the cylindrical connecting portion is pressed into the intermediate arc-shaped ring and the end arc-shaped ring through the opening. The number of the water-blocking cover is several. One or more intermediate arc-shaped rings are arranged on each water-blocking cover. The intermediate arc-shaped ring comprises a fixed plate. The fixed plate is fixedly arranged on the water-blocking cover support plate through bolts and flat washers. The end arc-shaped ring comprises a fixed plate and a limiting strip capable of limiting the axial movement of the cylindrical connecting portion. The fixed plate of the end arc-shaped ring is fixedly arranged on the water-blocking cover support plate through bolts and flat washers.

[0005] Preferably, two adjacent water-blocking covers are connected together in the intermediate arc-shaped ring.

[0006] Preferably, the two ends of the intermediate arc-shaped ring and the end arc-shaped ring are provided with protruding portions capable of overlapping with the arc-shaped installation groove.

[0007] Preferably, the back surface of the cover body is provided with several structure reinforcing ribs.

[0008] This invention has the following advantages over the prior art: the cylindrical connecting part of the water-retaining cover mates with the intermediate arc-shaped retaining ring and the end arc-shaped retaining ring. The opening size of the intermediate arc-shaped retaining ring and the end arc-shaped retaining ring is smaller than the diameter of the cylindrical connecting part. The intermediate arc-shaped retaining ring and the end arc-shaped retaining ring are made of elastic material, and the opening size can deform and increase under external force. Therefore, the cylindrical connecting part of the water-retaining cover can be pressed into the opening of the intermediate arc-shaped retaining ring and the end arc-shaped retaining ring without easily coming out. The outer arc surface of the intermediate arc-shaped retaining ring and the end arc-shaped retaining ring mate with the arc-shaped mounting groove on the water-retaining cover support plate. The bolts at both ends, with flat washers, pass through the fixing plate and lock with the threaded holes on the water-retaining cover support plate, restricting the axial movement of the water-retaining cover. The intermediate arc-shaped retaining ring is directly locked in the threaded hole on the water-retaining cover support plate by bolts and flat washers at the middle position.

[0009] The limiting strip can effectively restrict the movement of the water baffle. The two ends of the water baffle are not easy to fall out when rotating around the end arc retaining ring, and it is firmly fixed. The number of water baffles and the middle arc retaining ring can be increased or decreased according to different machine sizes. This fit is simple and firm, and effectively reduces the vibration of the loom during high-speed operation. Attached Figure Description

[0015] The invention will now be further described with reference to the accompanying drawings.

[0016] like Figure 1As shown, the water cover structure of a water jet loom comprises a water cover support plate 1, an intermediate arc-shaped ring 2, an end arc-shaped ring 3 and a water cover 4. The water cover support plate 1 is provided with an arc-shaped accommodation groove 5. The intermediate arc-shaped ring 2 and the end arc-shaped ring 3 are arranged in the arc-shaped accommodation groove 5. The water cover 4 comprises a cover body 6 and a cylindrical connecting portion 7 connected with the cover body 6. The opening size of the intermediate arc-shaped ring 2 and the end arc-shaped ring 3 is smaller than the diameter of the cylindrical connecting portion 7. The opening of the intermediate arc-shaped ring 2 and the end arc-shaped ring 3 is deformable, and the cylindrical connecting portion 7 is pressed into the intermediate arc-shaped ring 2 and the end arc-shaped ring 3 through the opening. The number of the water covers 4 is several. Each water cover 4 is provided with one or several intermediate arc-shaped rings 2. The intermediate arc-shaped ring 2 comprises a fixing plate 8. The fixing plate 8 is fixedly arranged on the water cover support plate 1 through a bolt 9 and a flat washer 10. The end arc-shaped ring 3 comprises a fixing plate 8 and a limiting strip 11 capable of limiting the axial movement of the cylindrical connecting portion 7. The fixing plate 8 of the end arc-shaped ring 3 is fixedly arranged on the water cover support plate 1 through the bolt 9 and the flat washer 10.

[0017] The water cover structure of the water jet loom comprises the cylindrical connecting portion 7 of the water cover 4 and the intermediate arc-shaped ring 2 and the end arc-shaped ring 3. The opening size of the intermediate arc-shaped ring 2 and the end arc-shaped ring 3 is smaller than the diameter size of the cylindrical connecting portion 7. The intermediate arc-shaped ring 2 and the end arc-shaped ring 3 are made of elastic material, which can be elastic steel sheet or plastic. The opening size can be deformed and increased under external force. Therefore, the cylindrical connecting portion 7 of the water cover 4 can be pressed into the opening of the intermediate arc-shaped ring 2 and the end arc-shaped ring 3 and will not easily come out. The outer circular arc surface of the intermediate arc-shaped ring 2 and the end arc-shaped ring 3 cooperates with the arc-shaped accommodation groove 5 on the water cover support plate 1. The bolts 9 at both ends cooperates with the flat washers 10 to pass through the fixing plate 8 and then cooperates with the threaded holes on the water cover support plate 1 to lock tightly, thereby limiting the axial movement of the water cover 4. The intermediate position directly uses the bolt 9 to cooperate with the flat washer 10 to lock the intermediate arc-shaped ring 2 in the threaded hole on the water cover support plate 1.

[0018] The limiting strip 11 can effectively limit the movement of the water cover 4. When the water cover 4 rotates around the end arc-shaped ring 3 at both ends, it is not easy to come out and is firmly fixed. The number of the water covers 4 and the intermediate arc-shaped rings 2 can be increased or decreased according to different sizes of the machine. The cooperation is simple, firm, and can effectively reduce the vibration in the high-speed operation of the loom. The setting of the intermediate arc-shaped ring 2 can reduce the vibration amplitude of the water cover 4.

[0019] Preferably, two adjacent water covers 4 are jointly connected in the intermediate arc-shaped ring 2.

[0020] Preferably, the middle arc-shaped clasp 2 and the two ends of the end arc-shaped clasp 3 are provided with protrusions 12 capable of overlapping the arc-shaped accommodation groove 5. The protrusions 12 are provided to prevent the middle arc-shaped clasp 2 and the end arc-shaped clasp 3 from being separated from the arc-shaped accommodation groove 5.

[0021] Preferably, the back of the cover 6 is provided with a plurality of structural reinforcing ribs 13. The structural reinforcing ribs 13 are provided to improve the structural strength of the cover 6.
