Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Please refer to Figures 1-3 As shown in the figure, a wire changing mechanism for carpet weaving includes a bracket 5. A transmission belt 2 driven to rotate reciprocally by a driving mechanism is provided on the bracket 5. A plurality of wire clamping assemblies 3 are fixedly connected along the length direction on the outer side of the transmission belt 2.

[0028] The wire clamping assembly 3 includes a fixing block 32, a fixed clamping block 33, a movable clamping block 34 and a spring 35. Through holes 39 for threading wires are formed at both ends of the fixing block 32. The fixed clamping block 33 is located between the two through holes 39 and fixedly connected to the fixing block 32. The movable clamping block 34 is slidably connected to the fixing block 32. The spring 35 acts on the movable clamping block 34 to cooperate with the fixed clamping block 33 to clamp the wire.

[0029] During use, the ends of different color wires are clamped by a plurality of wire clamping assemblies 3. When changing the wire, the current wire is cut off, and then the driving mechanism drives the transmission belt 2 to rotate, so that the wire clamping assembly 3 clamping the required color wire rotates to one end of the transmission belt 2 for easy access to the wire, thus making wire changing and wire taking more convenient. When taking the wire, the wire should be taken and cut from the end where the wire passes through the wire clamping assembly 3 to avoid the wire coming off the wire clamping assembly 3 after taking, which affects its next use.

[0030] When clamping the wire, the end of the wire is sequentially passed through the two through holes 39, and the wire is clamped by the fixed clamping block 33 and the movable clamping block 34. The wire is clamped by the fixed clamping block 33 and the movable clamping block 34 and limited by the through holes 39 to prevent the wire from coming off the wire clamping assembly 3 during the wire changing process.

[0031] In some embodiments, the driving mechanism includes a pulley 1 and a servo motor 4. Pulleys 1 are rotatably connected to both ends of the bracket 5. The transmission belt 2 is sleeved on the outer sides of the two pulleys 1. One of the pulleys 1 is driven to rotate by the servo motor 4.

[0032] Specifically, the pulley 1 is a synchronous pulley, and the transmission belt 2 is a synchronous belt.

[0033] The servo motor 4 is adopted to drive the synchronous belt to rotate through the synchronous pulley, improving the transmission accuracy and reducing the wire change error.

[0034] In some embodiments, a guide post 38 is fixedly connected to one side of the fixed block 32. The movable clamping block 34 is sleeved outside the guide post 38. A retaining ring 37 is fixedly connected to one end of the guide post 38 away from the fixed block 32. The spring 35 is sleeved outside the guide post 38. Preferably, chamfers are provided on the adjacent side edges of the fixed clamping block 33 and the movable clamping block 34, so as to place the wire between the fixed clamping block 33 and the movable clamping block 34 by setting the chamfers.

[0035] The movable clamping block 34 is limited and guided by setting the guide post 38 to prevent the movable clamping block 34 from being misaligned with the fixed clamping block 33. The spring 35 is arranged between the movable clamping block 34 and the retaining ring 37. When the spring 35 presses on the movable clamping block 34, the wire is clamped by the fixed clamping block 33 and the movable clamping block 34.

[0036] Specifically, a sliding sleeve 36 is fixedly connected to one side of the movable clamping block 34. The sliding sleeve 36 is sleeved outside the guide post 38. By setting the sliding sleeve 36, the guiding effect is enhanced, and the inclination of the movable clamping block 34 is avoided, which affects the clamping of the wire.

[0037] In order to avoid wire abrasion, a silica gel sleeve 31 is provided in the wire threading hole 39, and a tapered opening is provided at the end of the silica gel sleeve 31. By setting the silica gel sleeve 31, when the wire is taken, the friction between the wire and the fixed block 32 is avoided, resulting in wire abrasion.

[0038] In order to avoid interference between adjacent two wire clamping assemblies 3, the fixed clamping blocks 33 of adjacent two wire clamping assemblies 3 are distributed in a staggered manner.

[0039] In some embodiments, the bracket 5 includes a movable plate 51 and a frame body 54. Two movable plates 51 are fixedly connected to both ends of the frame body 54 through bolts. The belt pulley 1 is rotatably connected to the movable plate 51 through a bearing.

[0040] Specifically, a slider 52 is provided on one side of the movable plate 51, and a chute 53 adapted to the slider 52 is opened on the outside of the frame body 54.

[0041] By setting the slider 52 and the chute 53, the movable plate 51 is limited under the cooperation of the two, ensuring its assembly accuracy.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
