The bottom outer surface of the horizontal plate 2 and the bottom inner surface of the stretching box 1 are both fixedly connected with two vertical plates 5, and the outer surfaces of the upper two vertical plates 5 and the lower two vertical plates 5 are both rotatably penetrated by a transmission shaft 6, and the outer surfaces of the two transmission shafts 6 are movably sleeved with a lever 9, and the top outer surfaces and bottom outer surfaces of the two connecting seats 7 are both fixedly connected with a connecting plate 10, and the inner surfaces of the left and right sides of the stretching box 1 are both fixedly connected with two side plates, and a return spring 11 is fixedly connected between the upper two connecting plates 10 and the outer surfaces opposite to the side plates and between the lower two connecting plates 10 and the outer surfaces opposite to the side plates. Specifically, the transmission shaft 6 rotates When the lever 9 moves, it drives the lever 9 on it to rotate. When the end of the lever 9 away from the transmission shaft 6 rotates to the top, the lower lever 9 contacts the lower connecting plate 10, and as the lever 9 rotates, the lever 9 drives the connecting plate 10 to move upward, so that the connecting seat 7 drives the two stretching rollers 8 to drive the colored yarn upward to stretch it.

[0038] During the specific implementation process, according to the actual stretching requirements, when it is necessary to adjust the stretching force of the colored yarn, the connection position of the lever 9 and the transmission shaft 6 can be adjusted. At this time, unscrew the threaded disk 14, remove the lever 9, and then insert the circular hole corresponding to the lever 9 into the transmission shaft 6, and abut it against the positioning disk 12, and then screw the threaded disk 14 into the threaded teeth 13, and fix the lever 9 by cooperating with the threaded disk 14 and the positioning disk 12, so that the stretching force of the colored yarn can be adjusted.

[0039] Embodiment 3:

[0040] Please refer to Figure 6-Figure 9 The present invention provides a technical solution: in this embodiment, the interior of the stretching box 1 is rotatably connected to support rollers 15 at both the front and rear ends, and the right outer surface of the stretching box 1 is rotatably penetrated by two connecting shafts 16, which are respectively located above the two supporting rollers 15, and the outer surfaces of the two connecting shafts 16 are fixedly sleeved with clamping frames 17, which are mirror-set, and the interiors of the two clamping frames 17 are rotatably connected to clamping rollers 18. Specifically, the clamping frame 17 on the rear side is moved so that the two connecting shafts 16 can respectively drive the two clamping frames 17 to move in opposite directions until the clamping rollers 18 cooperate with the supporting rollers 15 to clamp and fix the colored yarn.

[0041] In this embodiment, the right outer surface of the stretching box 1 is rotatably connected to two rotating shafts, and the outer surfaces of the two rotating shafts are fixedly sleeved with transmission gears 19, and the outer surfaces of the two transmission gears 19 are movably meshed. The outer surfaces of the two transmission shafts 6 and the two connecting shafts 16 are fixedly sleeved with first transmission wheels 20, and the outer surfaces of the two first transmission wheels 20 on the front side and the two first transmission wheels 20 on the rear side are both wound with a first belt 21. Specifically, the clamping frame 17 on the rear side is moved to rotate the connecting shaft 16 on the rear side. When the connecting shaft 16 on the rear side rotates, the first transmission wheel 20 thereon is driven to rotate, and the transmission gear 19 on the front side is driven to rotate under the action of the first belt 21 on the rear side. The two transmission gears 19 rotate, thereby rotating the rotating shaft, and the first transmission wheel 20 on the rotating shaft on the front side is rotated, and the connecting shaft 16 on the front side is rotated under the action of the first belt 21, so that the two connecting shafts 16 rotate in opposite directions.

[0042] In this embodiment, a limit plate 22 is fixedly sleeved on the left outer surface of the rear connecting shaft 16, a support plate is fixedly connected to the left outer surface of the stretching box 1, a limit rod 23 is movably inserted on the outer surface of the support plate, a plurality of limit grooves 25 are opened on the outer surface of the limit plate 22 in a circumferential array, a limit block 26 adapted to the limit groove 25 is fixedly connected to the top outer surface of the limit rod 23, a limit spring 24 is fixedly connected between the limit block 26 and the outer surface opposite to the support plate, and the limit spring 24 is sleeved on the limit rod 23 The outer surface of the limit rod 23 is specifically pulled downward to compress the limit spring 24, and the limit rod 23 drives the limit block 26 to disengage from the inside of the limit groove 25, thereby releasing the limit on the limit plate 22, and stopping applying force to the limit rod 23 so that the limit spring 24 is reset. The limit spring 24 drives the limit rod 23 so that the limit block 26 is inserted into the limit groove 25, and the limit plate 22 is limited, thereby limiting the connecting shaft 16 to prevent the connecting shaft 16 from rotating, so that the clamping frame 17 drives the clamping roller 18 to move.

[0043] During the specific implementation process, when the colored yarn is being stretched, it is fixed. At this time, the colored yarn is first passed through the top of the two supporting rollers 15, and the limit rod 23 is pulled downward to compress the limit spring 24. The limit rod 23 drives the limit block 26 to disengage from the inside of the limit groove 25, and the limit plate 22 is released. At this time, the connecting shaft 16 can rotate, and the clamping frame 17 on the rear side is moved to make the connecting shaft 16 on the rear side rotate. When the connecting shaft 16 on the rear side rotates, it drives the first transmission wheel 20 thereon to rotate, and under the action of the first belt 21 on the rear side, it drives the transmission gear 19 on the front side to rotate. The two transmission gears 19 rotate, thereby rotating the rotating shaft, and making the first transmission on the rotating shaft on the front side rotate. The wheel 20 rotates, and the front connecting shaft 16 rotates under the action of the first belt 21. The two connecting shafts 16 rotate in opposite directions, so that the clamping frame 17 drives the clamping roller 18 to move, until the clamping roller 18 cooperates with the supporting roller 15 to clamp and fix the colored yarn, and then stops applying force to the limit rod 23, so that the limit spring 24 is reset, and the limit spring 24 drives the limit rod 23 to make the limit block 26 insert into the limit groove 25, and limit the limit plate 22, thereby limiting the connecting shaft 16 to prevent the connecting shaft 16 from rotating, so that the clamping frame 17 drives the clamping roller 18 to move, so that the colored yarn can be fixed during stretching, and the displacement of the colored yarn during stretching is prevented, which affects the stretching effect.

[0044] Working principle: In actual use of the present invention, the colored spun yarn passes through the stretching box 1 and passes it between the two stretching rollers 8, the motor 4 is turned on, the motor 4 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the active bevel gear 27 to rotate, the active bevel gear 27 drives the driven bevel gear 28 to rotate, so that the upper transmission shaft 6 rotates, when the upper transmission shaft 6 rotates, it drives the second transmission wheel 30 on the upper transmission shaft 6 to rotate, and under the action of the second belt 31, drives another second transmission wheel 30 to rotate, thereby drives the support shaft 29 to rotate, and then drives the third transmission wheel 32 on the support shaft 29 to rotate, and drives another third transmission wheel 32 to rotate under the action of the third belt 33, thereby drives the lower transmission shaft 6 to rotate, the two transmission shafts 6 rotate together, and the transmission shaft 6 drives the lever 9 thereon to rotate when rotating, and when the lever 9 rotates to the top away from one end of the transmission shaft 6, the lower lever 9 and the lower connecting plate When the upper lever 9 is away from one end of the transmission shaft 6 and rotates to contact with the lower connecting plate 10, as the lever 9 rotates, the lever 9 drives the connecting plate 10 downward, so that the connecting seat 7 drives the two stretching rollers 8 to drive the colored yarn downward and stretch it. When the lever 9 is disengaged from the connecting plate 10, the reset spring 11 drives the connecting plate 10 so that the connecting seat 7 drives the stretching rollers 8 to reset, thereby driving the colored yarn to reset, thereby driving the intermittent up and down dynamic stretching of the colored yarn with the rotation of the transmission shaft 6, which maximizes the toughness of the colored yarn and improves the quality of the colored yarn finished product. When it is necessary to statically stretch the colored yarn, when the lever 9 is rotated to support the colored yarn to the required position, the motor 4 stops working.

[0045] According to actual stretching requirements, when it is necessary to adjust the stretching strength of the colored yarn, the connection position of the lever 9 and the transmission shaft 6 can be adjusted. At this time, unscrew the threaded disk 14, remove the lever 9, and then insert the circular hole corresponding to the lever 9 into the transmission shaft 6, and abut it against the positioning disk 12, and then screw the threaded disk 14 into the thread teeth 13, and fix the lever 9 by cooperating with the threaded disk 14 and the positioning disk 12, so that the stretching strength of the colored yarn can be adjusted.

[0046] When the colored yarn is being stretched, it is fixed. At this time, the colored yarn is first passed over the two supporting rollers 15, and the limiting rod 23 is pulled downward to compress the limiting spring 24. The limiting rod 23 drives the limiting block 26 to disengage from the inside of the limiting groove 25, and the limiting plate 22 is released. At this time, the connecting shaft 16 can rotate, and the clamping frame 17 on the rear side is moved to make the connecting shaft 16 on the rear side rotate. When the connecting shaft 16 on the rear side rotates, it drives the first transmission wheel 20 thereon to rotate, and under the action of the first belt 21 on the rear side, it drives the transmission gear 19 on the front side to rotate. The two transmission gears 19 rotate, thereby rotating the rotating shaft, and causing the first transmission wheel 20 on the rotating shaft on the front side to rotate. The first belt 21 is moved, and the front connecting shaft 16 is rotated under the action of the first belt 21. The two connecting shafts 16 rotate in opposite directions, so that the clamping frame 17 drives the clamping roller 18 to move, until the clamping roller 18 cooperates with the supporting roller 15 to clamp and fix the colored yarn, and then stop applying force to the limit rod 23, so that the limit spring 24 is reset, and the limit spring 24 drives the limit rod 23 to make the limit block 26 insert into the limit groove 25, and limit the limit plate 22, so as to limit the connecting shaft 16 to prevent the connecting shaft 16 from rotating, so that the clamping frame 17 drives the clamping roller 18 to move, so that the colored yarn can be fixed during stretching, and the displacement of the colored yarn during stretching is prevented, which affects the stretching effect.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
