Description

Technical Field

[0001] The utility model relates to the technical field of rapier looms, in particular to a rapier belt deflection adjustment structure for rapier looms. Background Art

[0002] Due to its own gravity, the sword belt will have a certain deflection when it is extended. In the long-term use process, the sword belt will be repeatedly subjected to the effects of stretching, friction and other forces, and its material properties will gradually change, resulting in changes in deflection. As the use time increases, the sword belt material will gradually age and its elasticity will decrease, resulting in greater deformation when subjected to the same external force, that is, increased deflection. The change in deflection will cause the movement trajectory of the sword belt to change during the weft insertion process, thereby affecting the accuracy and quality of the fabric. The change in deflection will accelerate the wear and damage of the sword belt, resulting in the need for more frequent repairs and replacements. This not only increases the cost of repairs, but may also lead to production interruptions and delays. Utility Model Content

[0003] In order to solve the above technical deficiencies, the utility model provides a rapier loom belt deflection adjustment structure, which can adjust the deflection of the rapier belt.

[0004] The utility model discloses a rapier loom sword belt deflection adjustment structure, comprising a frame, a sword transmission wheel is rotatably connected on the frame, a sword belt is wound on the sword transmission wheel, a pressure block is arranged above the sword transmission wheel, the pressure block is slidably matched to press against the outer surface of the sword belt and makes the sword belt move in and out tangentially along the sword transmission wheel, a connecting piece is arranged at the extended end of the sword belt, a No. 1 through hole is arranged on the pressure block along the extended direction of the sword belt, a fixing seat is arranged on the side of the pressure block away from the extended end of the sword belt, a threaded hole is arranged on the fixing seat along the extended direction of the sword belt, a bolt is arranged in the threaded hole, a No. 2 through hole is arranged on the bolt along the central axis thereof, an elastic piece is arranged on the upper side of the sword belt, one end of the elastic piece is connected to the connecting piece, and a clamping block is arranged at the end after the other end of the elastic piece passes through the No. 1 through hole and the No. 2 through hole, and the clamping block presses against the bolt.

[0005] The principle of the above technical solution is that when the sword belt is extended, the elastic member is stretched, and as the sword belt is extended, the tension of the elastic member gradually increases to pull the sword belt, thereby reducing the deflection of the sword belt. After being used for a long time, the material of the sword belt will gradually age and its elasticity will decrease, thereby producing a greater deformation when subjected to the same external force, that is, the deflection increases. At this time, by adjusting the bolt, the tension of the elastic member is increased to pull the sword belt, thereby reducing the deflection of the sword belt. The other end of the elastic member is provided with a block at the end after passing through the No. 1 through hole and the No. 2 through hole, and the block is pressed against the bolt. Such a design can prevent the elastic member from rotating with the bolt when the bolt is adjusted.

[0006] Preferably, the elastic member is a spring, which can be subjected to variable loads millions of times and has a long service life.

[0007] The utility model provides a rapier loom belt deflection adjustment structure, which has the beneficial effect that the deflection of the rapier belt can be greatly reduced by setting the elastic member, and the tension of the elastic member can be adjusted by setting the bolt to match the deflection change caused by long-term use of the rapier belt.

[0010] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0011] Embodiment 1:

[0012] like Figure 1 , 2 As shown, the utility model discloses a rapier loom sword belt deflection adjustment structure, comprising a frame 1, a sword transmission wheel 2 is rotatably connected to the frame 1, a sword belt 5 is wound on the sword transmission wheel 2, a pressure block 4 is arranged above the sword transmission wheel 2, the pressure block 4 is slidably fitted to press against the outer surface of the sword belt 5 and make the sword belt 5 move in and out tangentially along the sword transmission wheel 2, a connecting piece 6 is arranged at the protruding end of the sword belt 5, a No. 1 through hole is arranged on the pressure block 4 along the protruding direction of the sword belt 5, a fixing seat 7 is arranged on the side of the pressure block 4 away from the protruding end of the sword belt 5, a threaded hole is arranged on the fixing seat 7 along the protruding direction of the sword belt 5, a bolt 8 is arranged in the threaded hole, a No. 2 through hole is arranged on the bolt 8 along its central axis, a spring 3 is arranged on the upper side of the sword belt 5, one end of the spring 3 is connected to the connecting piece 6, and the other end of the spring 3 is provided with a clamping block 9 at the end after passing through the No. 1 through hole and the No. 2 through hole, and the clamping block 9 presses on the bolt 8.

[0013] The principle of the above technical solution is that when the sword belt 5 is extended, the spring 3 is stretched, and as the sword belt 5 is extended, the tension of the spring 3 gradually increases to pull the sword belt 5, so that the deflection of the sword belt 5 becomes smaller. After being used for a long time, the material of the sword belt 5 will gradually age and the elasticity will decrease, so that when subjected to the same external force, a greater deformation will be generated, that is, the deflection will increase. At this time, by adjusting the bolt 8, the tension of the spring 3 is increased to pull the sword belt 5, so that the deflection of the sword belt 5 becomes smaller. The other end of the spring 3 passes through the No. 1 through hole and the No. 2 through hole, and a clamping block 9 is provided at the end. The clamping block 9 presses against the bolt 8. Such a design can prevent the spring 3 from rotating with the bolt 8 when the bolt 8 is adjusted.
