[0028] The middle part of the installation side plate 201 is provided with a first vertical groove 205 and a second vertical groove 206;

[0029] The inside of the first vertical groove 205 is slidably connected with a sliding block 207, the two sliding blocks 207 are rotatably connected with a tightening roller 208, the inside of the second vertical groove 206 is slidably connected with an extension screw 209, the extension screw 209 is connected with a plurality of counterweight pieces 210, and the extension screw 209 is threadedly connected with a threaded cap 212; the counterweight pieces 210 are in the shape of a round piece; under the weight of the tightening roller 208 in a normal state, the yarn is kept tight, and because the weight of the tightening roller 208 is fixed, the yarn keeps tight under the same force regardless of the length of the redundant section, thereby avoiding breakage and keeping the yarn tight.

[0030] The first vertical groove 205 and the second vertical groove 206 are communicated, the first vertical groove 205 and the second vertical groove 206 are located between the first rotating roller 202 and the second rotating roller 203, and the height of the tightening roller 208 is lower than that of the first rotating roller 202.

[0031] The middle part of the bundling strip 204 is provided with a stabilizing hole 213, one side of the bundling strip 204 close to the tightening roller 208 is fixedly connected with a pair of extension plates 214, and the two extension plates 214 are rotatably connected with an anti-abrasion wheel 215; the stabilizing hole 213 avoids the shaking of the yarn when the winding mechanism 101 is winding.

[0032] The first rotating roller 202 and the second rotating roller 203 are both in rotating connection with the mounting side plate 201, and the cluster strip 204 is fixedly connected with the mounting side plate 201; the first rotating roller 202 can guide the yarn more gently to pass below the taut roller 208, and the second rotating roller 203 and the anti-abrasion wheel 215 can better guide the yarn into the stable hole 213, and the anti-abrasion wheel 215 can reduce the friction between the extension plate 214 and the yarn.

[0033] The sliding block 207 is fixedly connected with one end of the extension screw rod 209, the counterweight sheet 210 is provided with a plurality of specifications, and a center groove 211 is formed in the middle part of the counterweight sheet 210 and is inserted with the extension screw rod 209.

[0034] The outer side of the mounting side plate 201 is provided with a storage assembly 3, which comprises a storage shell 301 fixed to the outer side of the mounting side plate 201, and an outer groove 302 is formed in the outer side of the storage shell 301; the inner bottom surface of the storage shell 301 is V-shaped, the width of the storage shell 301 is greater than that of the maximum diameter of the counterweight sheet 210; the V-shaped bottom surface of the storage shell 301 can guide the counterweight sheet 210 to automatically move to the middle part, at this time, the center groove 211 coincides with the outer groove 302, so that the center groove 211 can be inserted by the finger through the outer groove 302 at this time, and the counterweight sheet 210 can be taken out from the storage shell 301.

[0035] Working principle: Before using the spinning and twisting machine with adjustable tightness, the overall situation of the device needs to be checked to determine whether it can work normally, and according to the diameter of the yarn to be processed, the corresponding counterweight sheet 210 is selected and inserted into the center groove 211 of the extension screw rod 209, and then the threaded cap 212 is installed, so that the counterweight sheet 210 cannot be separated, thereby increasing the weight of the taut roller 208 and the extrusion force of the taut roller 208 on the yarn, so that the device can adaptively adjust the pressure on the yarn of different diameters and keep it tight better. Figure 1 Figure 5 As shown, first, the yarn is passed through the first rotating roller 202 and the bottom of the taut roller 208, then passes around the top of the second rotating roller 203 and the anti-abrasion wheel 215, and finally passes through the stable hole 213 and is received by the winding mechanism 101;

[0036] Under the normal weight, the taut roller 208 can keep the yarn taut, and because the weight of the taut roller 208 is fixed, the yarn can keep tight under the same force regardless of the length of the redundant segment, which can prevent the yarn from breaking and keep it tight;

[0037] When the yarn is relatively thick and the shaking during processing is large, the weight of the taut roller 208 cannot stably press the yarn, the appropriate weight of the counterweight sheet 210 is taken out from the storage shell 301, the center groove 211 is inserted into the extension screw rod 209, and then the threaded cap 212 is installed, so that the counterweight sheet 210 cannot be separated, thereby increasing the weight of the taut roller 208 and the extrusion force of the taut roller 208 on the yarn, so that the device can adaptively adjust the pressure on the yarn of different diameters and keep it tight better;

[0038] ​The first rotating roller 202 can guide the yarn more gently to pass under the tension roller 208, and the second rotating roller 203 and the wear-proof wheel 215 can guide the yarn to enter the stable hole 213 better, and the wear-proof wheel 215 can reduce the friction between the extension plate 214 and the yarn;

[0039] When the weight piece 210 is not installed, the threaded cap 212 is close to the outer side of the installation side plate 201, the height of the tension roller 208 can be fixed, so that the yarn can keep loose in the area under the tension roller 208, and when the redundant length is reduced, the yarn can automatically contact and keep tension with the tension roller 208;

[0040] The V-shaped bottom surface of the storage shell 301 can guide the position of the weight piece 210 to move to the middle part automatically, at this time, the center groove 211 is coincided with the outer groove 302, so that the finger can pass through the outer groove 302 to insert into the center groove 211, and the weight piece 210 can be taken out from the storage shell 301 conveniently.
