The slide block 411 is slidably mounted in the slide groove 32, and the threaded rod 321 is rotatably mounted in the slide groove 32, and the length direction of the threaded rod 321 is consistent with the length direction of the slide groove 32. The threaded rod 321 passes through the slider 411 and is threadedly connected to the slider 411. The frame 3 is provided with a driving assembly for driving the threaded rod 321 to rotate, the driving assembly includes two worm wheels (not shown) and a worm 5, and the two worm wheels are respectively and fixedly mounted on the lower end portions of the threaded rods 321 on the two sides of the frame 3. The worm 5 is rotatably mounted on the frame 3, and the length direction of the worm 5 is perpendicular to the length direction of the threaded rod 321. Two sections of same spiral teeth are arranged at two ends of the worm 5, and the two sections of spiral teeth are respectively meshed with the two worm wheels. Mounting bracket 41 both ends respectively with two slider 411 fixed connection, therefore mounting bracket 41 can slide along vertical direction on frame 3 to worm 5 can drive the synchronous vertical slip in both ends of mounting bracket 41, makes mounting bracket 41's removal more firm.

Referring to fig. 1 and 3, a runner 51 is fixedly attached to one end of the worm 5. The worm 5 is also provided with a limiting assembly, and the limiting assembly comprises a ratchet wheel 52, a pawl 53 and a locking spring 54. The ratchet wheel 52 is fixedly arranged on the worm 5 and is positioned on one side of the rotating wheel 51 close to the worm 5; one end of the pawl 53 is rotationally connected with the frame 3, and the other end is embedded in a tooth groove of the ratchet wheel 52; one end of the locking spring 54 is fixedly connected with the frame 3, and the other end is fixedly connected with the lower surface of the middle position of the pawl 53. When the rotating wheel 51 rotates, the ratchet wheel 52 rotates along with the rotating wheel, the pawl 53 is continuously embedded in the tooth groove of the ratchet wheel 52, and when the rotating wheel 51 has a tendency of reverse rotation, the pawl 53 is abutted in the tooth groove of the ratchet wheel 52 to prevent the rotating wheel 51 from rotating reversely; when reverse rotation is required, the rotating wheel 51 can be reversed only by pulling the pawl 53 open; the locking spring 54 can provide a downward bias to the pawl 53, reducing the possibility of the pawl 53 falling out, further limiting the ratchet 52 from reversing.

Referring to fig. 2 and 4, the upper tension roller 43 is rotatably mounted on the mounting bracket 41, and the length direction of the upper tension roller 43 is parallel to the length direction of the cloth inlet 2. The relative one side of mounting bracket 41 has all been seted up spout 6, and spout 6 just is "L" shape along vertical setting, and spout 6 is located the below of tight roller both ends position. The sliding base 61 is slidably mounted in the sliding groove 6, the sliding base 61 is also in an "L" shape, the sliding base 61 has a horizontal portion 611 and a vertical portion 612, two ends of the lower tension roller 42 are rotatably mounted on the horizontal portion 611 of the sliding base 61, and the lower tension roller 42 is parallel to the upper tension roller 43.

An adjusting assembly for adjusting the position of the lower tension roller 42 is arranged on the mounting frame 41, and comprises a rack 71, an adjusting gear 72 and a positioning piece. The rack 71 is fixedly mounted on the end of the vertical portion 612 of the slide 61; a rotating handle 73 is rotatably mounted on the mounting frame 41, the rotating handle 73 and the rack 71 are located on the same side of the mounting frame 41, a rotating shaft of the rotating handle 73 penetrates through the center of the adjusting gear 72 and is fixedly connected with the adjusting gear 72, and the adjusting gear 72 is meshed with the convex teeth on the rack 71.

The positioning piece comprises a positioning hole 76, a locking hole 74 and a positioning pin 75, wherein the locking hole 74 is formed in the rack 71, a plurality of locking holes 74 are formed, and the locking holes 74 are vertically arranged at intervals. A positioning hole 76 is opened on a side of the mounting bracket 41 adjacent to the rack 71, and a locking hole 74 is always provided corresponding to the positioning hole 76. The positioning hole 76 is internally provided with threads, the positioning pin 75 is also provided with a thread section matched with the positioning hole 76, and the positioning pin 75 sequentially penetrates through the locking hole 74 and the positioning hole 76 and is in threaded connection with the positioning hole 76, so that the slide seat 61 is fixed.

Through rotatory turning handle 73, drive adjusting gear 72 and rotate to drive rack 71 and vertically slide, thereby drive slide 61 and vertically slide, thereby drive tensioning roller 42 down and keep away from or be close to last tensioning roller 43, treat tensioning roller 42 position adjustment's back down, make locating pin 75 insert in locating hole 76 through revolving wrong locating pin 75, thereby realize the fixed of tensioning roller 42 position down.

The working principle of the embodiment is as follows:

before the cloth enters the cylinder body 1, the position of the lower tensioning roller 42 is adjusted by rotating the rotating handle 73 according to the thickness of the cloth, and the position of the lower tensioning roller 42 is fixed through the positioning hole 76 and the positioning pin 75. The cloth is then passed between the gaps between the upper tension roller 43 and the lower tension roller 42. Then according to the elasticity state of cloth again, rotatory runner 51 drives worm 5 and rotates to drive the worm wheel and rotate, thereby drive the threaded rod 321 synchronous rotation of both sides, make the firm slip in mounting bracket 41 both ends, realize the adjustment of mounting bracket 41 height, make the cloth tensioning, afterwards again with the cloth around rolling up on the driving shaft, make the cloth at the dye-jigging in-process tensioning cloth, consequently can let the cloth in the fibre clearance great, increase the dye-jigging effect of cloth.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
