Description

Technical Field

[0001] The utility model belongs to the technical field of edge wire frames, in particular to a special edge wire frame for a projectile loom. Background Art

[0002] A projectile shuttle loom is a loom that uses a sheet-like weft clamp (projectile shuttle) to introduce the weft yarn into the shed. Usually in the loom, the edge wire frame is used to support and guide the edge of the fabric to ensure the flatness and tension of the fabric during the weaving process. Therefore, it can be seen that the existing edge wire frame basically meets people's practical needs, but the following problems still exist.

[0003] When the edge wire rack is in use, the operator sets the sleeve on the wire roller on the support frame, and then the operator installs the sleeve on the support frame by means of bolt threaded connection, thereby installing the wire roller on the support frame. When the operator needs to use bolts to install the sleeve on the wire roller and the support frame, the operator aligns the sleeve on the wire roller with the mounting holes opened on the support frame, and then the operator passes the bolts through the threaded holes opened in both, thereby performing threaded installation. When the operator aligns the mounting holes, the operator may need to move repeatedly to align the mounting holes of the two, which may cause the operator to be cumbersome when performing the installation. For this reason, we propose a special edge wire rack for shuttle looms. Utility Model Content

[0004] The utility model provides a special edge wire frame for a projectile shuttle loom. An operator takes a supporting plate, and after the supporting plate drives a mounting ring to be sleeved on the surface of a sleeve rod, the operator pulls the mounting ring on the surface of the sleeve rod through the supporting plate to move it. When the mounting holes opened on the mounting ring and the sleeve rod are aligned with each other, the elastic deformation of the second spring is restored, and the second spring pushes the screw rod to move through the mounting holes opened on the mounting ring and the sleeve rod surface, so that the screw rod passes through the mounting holes opened on the surface of the mounting ring and the sleeve rod, thereby facilitating the operator to align the mounting holes and improving the convenience of installation by the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special edge wire frame for a shuttle loom, comprising a mounting frame and a wire barrel, a sleeve rod is fixed at the end of the mounting frame, and a mounting ring is sleeved on the surface of the sleeve rod, the mounting ring is fixed on a support plate, and a rotating rod is fixed on the surface of the support plate, and a wire barrel is sleeved on the surface of the rotating rod, a second spring groove is opened in the middle of the sleeve rod, and a push block is elastically connected to the inner wall of the second spring groove, a screw rod passing through the second spring groove and the mounting ring is fixed on the surface of the push block, and a nut is threadedly installed on the surface of the screw rod, a connecting rod passing through the second spring groove is fixed to the outer wall of the push block, and a pressing block is fixed at the end of the connecting rod.

[0006] Further, a limiting sleeve is sleeved on the end of the rotating rod, and a pull rod penetrates through the middle of the limiting sleeve. A first spring groove is formed on the rotating rod and sleeved on the surface of the pull rod. A first spring is wound around the surface of the pull rod, and both ends of the first spring respectively abut between the surface of the pull rod and the inner wall of the first spring groove. A baffle is fixed to the end of the pull rod, and a positioning sleeve fixed on the limiting sleeve is sleeved around the baffle. An abutting ring is fixed to the end of the limiting sleeve, and the surface of the abutting ring is mutually attached to the surface of the thread barrel. A handle is fixed to the surface of the baffle.

[0007] Further, a stop rod is arranged between the mutual attachment of the abutting ring and the thread barrel, and a rotating shaft fixed on the inner wall of the storage groove penetrates through the end of the stop rod. The storage grooves are all formed on the rotating rod.

[0008] Further, rectangular grooves matching the number of the stop rods are formed around the abutting ring, and the rectangular blocks arranged on the stop rods are mutually matched with the rectangular grooves formed around the abutting ring.

[0009] Further, the baffle is arranged as a kidney-shaped block, and a kidney-shaped hole matching the baffle is formed in the middle of the positioning sleeve.

[0010] Further, traction rods fixed on the inner wall of the second spring groove symmetrically penetrate through both sides of the push block, and second springs are wound around the surfaces of the traction rods. Both ends of the second springs respectively abut between the inner wall of the second spring groove and the surface of the push block.

[0011] Further, extension sleeves are sleeved on the surfaces of the screw rods, and the extension sleeves are all fixed on the surfaces of the mounting rings.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The special side silk frame for this shuttle loom is provided with a push block, a second spring groove, a screw rod and a second spring. By the operator holding the thread barrel, the thread barrel drives the mounting ring to move through the support plate. After the mounting ring is sleeved on the surface of the sleeve rod, the operator pushes the mounting ring to move. After the mounting ring is aligned with the mounting hole formed on the surface of the sleeve rod, the screw rod is no longer extruded by the inner wall of the mounting ring. After the screw rod no longer presses the second spring through the push block, the elastic deformation of the second spring is restored. The second spring pushes the push block to move, so that the push block pushes the screw rod to move, and the screw rod penetrates through the mounting holes formed on the surfaces of the mounting ring and the sleeve rod, thus no longer requiring the operator to repeatedly push the mounting ring to move on the surface of the sleeve rod, improving the convenience for the operator to install the mounting ring.

[0014] 2. The special side wire holder of this loom is provided with a limit sleeve and a resisting ring. By the operator holding the limit sleeve, the limit sleeve drives the resisting ring to move. After the resisting ring and the limit sleeve are moved out from the surface of the rotating rod, the operator pulls the wire barrel, and the wire barrel falls off from the surface of the rotating rod, which is convenient for the operator to replace the wire barrel. When the operator replaces the used wire barrel, there is no need for the operator to disassemble the whole device from the mounting rack, improving the usability for the operator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to further understand the content, features and effects of the present utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0025] Embodiment:

[0026] Please refer to Figure 1 - Figure 7A special side wire frame for a projectile shuttle loom comprises a mounting frame 1 and a thread barrel 2, a sleeve rod 17 is fixed at the end of the mounting frame 1, and a mounting ring 16 is sleeved on the surface of the sleeve rod 17, the mounting ring 16 is fixed on a support plate 3, and a rotating rod 4 is fixed on the surface of the support plate 3, and a thread barrel 2 is sleeved on the surface of the rotating rod 4, a second spring groove 18 is opened in the middle of the sleeve rod 17, and a push block 21 is elastically connected to the inner wall of the second spring groove 18, and traction rods 19 fixed on the inner wall of the second spring groove 18 are symmetrically penetrated on both sides of the push block 21, and the surfaces of the traction rods 19 are all wound with second springs 20, and the ends of both sides of the second spring 20 are respectively abutted between the inner wall of the second spring groove 18 and the surface of the push block 21, and the push block 2 1 is fixed with a screw rod 23 penetrating the second spring groove 18 and the mounting ring 16, and a nut 24 is threadedly installed on the surface of the screw rod 23, and a connecting rod 25 penetrating the second spring groove 18 is fixed to the outer wall of the push block 21, and a pressing block 26 is fixed to the end of the connecting rod 25. When the operator needs to install the support plate 3 on the mounting frame 1, the operator first presses the screw rod 23. After the screw rod 23 is stressed, the screw rod 23 pushes the push block 21 to make the push block 21 slide in the second spring groove 18. When the push block 21 slides in the second spring groove 18, the circular through holes on both sides of the push block 21 slide on the surface of the cylindrical traction rod 19, and the push block 21 During movement, the push block 21 squeezes the second spring 20 wound on the surface of the traction rod 19, causing the second spring 20 to undergo elastic deformation. After the second spring 20 undergoes elastic deformation, the second spring 20 avoids the push block 21, causing the screw 23 to enter the second spring groove 18. Then the operator moves the support plate 3, and the support plate 3 drives the mounting ring 16 to move, causing the mounting ring 16 to be sleeved on the surface of the sleeve rod 17. When the mounting ring 16 slides on the surface of the sleeve rod 17, the through hole on the surface of the mounting ring 16 moves to the front end of the screw 23. After the screw 23 is no longer squeezed by the inner wall of the mounting ring 16, the screw 23 no longer pushes the second spring 20 through the push block 21. After the extrusion, the elastic deformation of the second spring 20 is restored, and the second spring 20 pushes the push block 21 to move, so that the push block 21 pushes the screw rod 23 to move, and the screw rod 23 passes through the through hole opened on the surface of the mounting ring 16, so that the screw rod 23 pre-fixes the mounting ring 16 on the sleeve rod 17, and then the operator sets the nut 24 on the surface of the screw rod 23, and then the operator screws the nut 24, so that the nut 24 and the screw rod 23 are threadedly matched with each other, and the mounting ring 16 is fixed on the mounting frame 1, so that the support plate 3 and the mounting frame 1 are connected to each other, and the operator no longer needs to repeatedly push the mounting ring 16 to move on the surface of the sleeve rod 17, thereby improving the convenience of the operator to install the mounting ring 16.

[0027] In other embodiments, a limiting sleeve 6 is sleeved on the end of the rotating rod 4, and a pull rod 15 passes through the middle of the limiting sleeve 6. A first spring groove 13 opened on the rotating rod 4 is sleeved on the surface of the pull rod 15, and a first spring 14 is wound around the surface of the pull rod 15. The two end portions of the first spring 14 respectively abut between the surface of the pull rod 15 and the inner wall of the first spring groove 13. A baffle 8 is fixed at the end of the pull rod 15, and a positioning sleeve 7 fixed on the limiting sleeve 6 is sleeved around the baffle 8. An abutting ring 5 is fixed at the end of the limiting sleeve 6, and the surface of the abutting ring 5 is mutually attached to the surface of the wire barrel 2. A grip 9 is fixed on the surface of the baffle 8. A stop rod 10 is arranged between the mutual attachment of the abutting ring 5 and the wire barrel 2, and a rotating shaft 11 fixed on the inner wall of the storage groove 12 passes through the end of the stop rod 10. The storage grooves 12 are all opened on the rotating rod 4. When the operator needs to replace the wire barrel 2, after the operator first holds the hand on the surface of the grip 9, the grip 9 drives the baffle 8 to move, the baffle 8 drives the pull rod 15 to slide in the first spring groove 13, and the pull rod 15 squeezes the first spring 14 to cause elastic deformation of the first spring 14. After the first spring 14 undergoes elastic deformation, the first spring 14 gives way to the pull rod 15, and the pull rod 15 moves out of the first spring groove 13, and the baffle 8 moves out of the positioning sleeve 7. Subsequently, the operator rotates the grip 9, and the grip 9 drives the pull rod 15 to rotate in the first spring groove 13 through the baffle 8, so that the kidney-shaped block arranged on the baffle 8 is aligned with the kidney-shaped hole opened in the middle of the positioning sleeve 7. Subsequently, the operator pulls the limiting sleeve 6, and the limiting sleeve 6 drives the abutting ring 5 to move, so that the abutting ring 5 moves out of the surface of the wire barrel 2. Subsequently, the operator pushes the wire barrel 2, and the wire barrel 2 slides on the surface of the rotating rod 4, and the rotating rod 4 pushes the stop rod 10, and the stop rod 10 rotates through the rotating shaft 11, so that the rotating shaft 11 enters the storage groove 12. Subsequently, the operator removes the wire barrel 2 from the surface of the rotating rod 4, improving the convenience for the operator to replace the rotating rod 4.

[0028] In other embodiments, rectangular grooves matching the number of the stop rods 10 are opened around the abutting ring 5, and the rectangular blocks arranged on the stop rods 10 are matched with the rectangular grooves opened around the abutting ring 5. By opening the rectangular grooves matching the number of the stop rods 10 around the abutting ring 5, the rectangular grooves opened around the abutting ring 5 can be sleeved on the surface of the stop rods 10, so that the rectangular grooves give way to the stop rods 10, increasing the stability of the abutting ring 5 attached to the surfaces of the mounting frame 1 and the wire barrel 2.

[0029] In other embodiments, the baffle 8 is arranged as a kidney-shaped block, and a kidney-shaped hole matching the baffle 8 is opened in the middle of the positioning sleeve 7. By matching the kidney-shaped block arranged on the baffle 8 with the kidney-shaped hole opened in the middle of the positioning sleeve 7, the baffle 8 can pass through the kidney-shaped hole opened in the middle of the positioning sleeve 7.

[0030] In other embodiments, extension sleeves 22 are sleeved on the surfaces of the screws 23, and the extension sleeves 22 are fixed on the surfaces of the mounting rings 16. By sleeving the extension sleeves 22 on the surfaces of the screws 23, the convenience of the movement of the screws 23 in the through holes formed on the surfaces of the mounting rings 16 is increased. At the same time, the ends of the extension sleeves 22 are arranged in parallel. After the nuts 24 are threadedly mounted on the surfaces of the extension sleeves 22, the frictional force between the nuts 24 and the surfaces of the extension sleeves 22 is increased, and the stability of the threaded mounting of the nuts 24 is improved.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
