Description

TECHNICAL FIELD

[0001] The utility model relates to the field of textile, concretely relates to a textile yarn tension control mechanism. BACKGROUND

[0002] In the textile production process, the tension control of yarn is crucial to ensure product quality and production efficiency. Too much or too little tension will affect the uniformity and strength of the yarn, and thus affect the quality of the final product. In the existing yarn tension control device, a position-adjustable compression wheel is usually used to control the yarn tension. However, in actual production process, the yarn is pulled to move, and the yarn and the equipment itself have certain vibration. The tension of the yarn is not stable at a fixed value, but randomly changes within a certain range. Therefore, in some existing yarn tension control devices, a buffer mechanism is usually provided for the compression wheel to move and reset within a certain range, so as to compensate for the real-time changes in the tension of the yarn. However, there is still a risk of yarn breakage due to excessive instantaneous tension of the yarn exceeding the compensation range of the buffer mechanism, which hinders continuous production. SUMMARY

[0003] The purpose of the utility model is to provide a textile yarn tension control mechanism. The mechanism extends the length of the buffer mechanism through the adjusting mechanism, thereby providing more movable space for the tension wheel and the slider to reduce the tension of the yarn and achieve the purpose of reducing the risk of yarn breakage.

DETAILED DESCRIPTION

[0017] The utility model will be made further detailed explanation in combination with the drawings and by example, the following example is the explanation of the utility model and the utility model is not limited to the following example.

[0018] Referring to Figures 1-3 The textile yarn tension control mechanism comprises a support 1, a sliding block 2, a tension wheel 3 and a buffer mechanism 4, the tension wheel 3 is rotatably arranged on the sliding block 2, the sliding block 2 is slidably arranged in the support 1, the buffer mechanism 4 is arranged on the upper and lower sides of the sliding block 2 and drives the sliding block 2 to reset, and the support 1 is provided with an adjusting mechanism 5 for controlling the length of the buffer mechanism 4.

[0019] The utility model discloses a yarn is set up on the tension wheel 3, the rotation of tension wheel 3 is convenient for the delivery of yarn, simultaneously realizes the tensioning effect to yarn through tension wheel 3, when the tension of yarn changes, tension wheel 3 can change position along with the up-down movement of sliding block 2, and resets under the action of buffer mechanism 4, so as to compensate the tension of yarn in a certain range.When the tension of yarn is too large, and tension wheel 3 has moved to the boundary position that buffer mechanism 4 can allow along with sliding block 2 and cannot continue to move, to reduce the tension of yarn, when the risk of yarn rupture exists, buffer mechanism 4 can extend its length under the action of adjusting mechanism 5, so as to provide tension wheel 3 and sliding block 2 with more movable space to reduce the tension of yarn, reduce the risk of yarn rupture, and guarantee the continuity of production.

[0020] Referring to Figure 1 , Figure 2 The buffer mechanism 4 comprises a sliding rod 41 and a plurality of springs 42, the sliding rod 41 is vertically arranged in the support 1, and the sliding block 2 is slidably arranged on the sliding rod 41, the spring 42 is sleeved on the sliding rod 41, and the upper and lower ends of the spring 42 are respectively arranged on the upper and lower sides of the support 1 and the sliding block 2.

[0021] By arranging the spring 42 on the upper and lower sides of the sliding block 2, when the tension of yarn changes, the sliding block 2 moves up and down on the sliding rod 41 and can reset under the action of the spring 42, realizing the real-time compensation effect of the buffer mechanism 4 on the tension of yarn, and ensuring that the tension of yarn can be maintained within the required range.

[0022] Referring to Figure 1 , Figure 2The adjusting mechanism 5 comprises a motor 51 and a plurality of sleeves 52, the support 1 comprises a fixed part 11 and a sliding part 12, the sliding part 12 is slidably arranged on the lower side of the fixed part 11, the springs 42 on the upper and lower sides of the sliding block 2 are respectively arranged on the fixed part 11 and the sliding part 12, the upper and lower ends of the slide rod 41 are respectively arranged on the upper and lower sides of the support 1 and pass through the fixed part 11 and the sliding part 12, the upper and lower ends of the slide rod 41 are provided with nuts 53 through threaded structures, the sleeves 52 are clamped between the nuts 53 and the support 1, the motor 51 is fixed on the lower side of the sliding part 12, coaxially fixed gears 54 that are meshed with each other are arranged on the rotating shaft of the motor 51 and the nut 53 on the lower side of the sliding part 12, and the switch mechanism 6 that triggers the operation of the motor 51 is arranged in the fixed part 11.

[0023] When the yarn tension increases, the tensioning wheel 3 and the sliding block 2 move downwards along the slide rod 41, and the spring 42 on the lower side of the sliding block 2 is compressed, and when the yarn tension is too large and the sliding block 2 moves to the position where the spring 42 on the lower side of the sliding block 2 cannot be further compressed, the motor 51 is operated through the switch mechanism 6, the gear 54 fixed on the rotating shaft of the motor 51 drives the meshed gear 54 to rotate, thereby driving the nut 53 on the lower side of the sliding part 12 to rotate and move downwards, at this time, the sliding part 12 and the sleeve 52 can be driven to move downwards under the action of the spring 42, so that the distance between the upper end of the sliding part 12 and the fixed part 11 is increased, the spring 42 is elongated to release the elastic force, at this time, the tensioning wheel 3 and the sliding block 2 can further move downwards to reduce the yarn tension, thereby increasing the compensation range of the buffer mechanism 4 to the yarn tension and reducing the risk of yarn breakage.

[0024] Referring to Figure 2 , Figure 3 The switch mechanism 6 comprises a reset switch 61 and a vertical rod 62, a vertical sliding groove 13 is arranged on the rear side of the fixed part 11, a pressing rod 21 is fixed on the rear side of the sliding block 2, the pressing rod 21 is slidably arranged in the sliding groove 13 and moves up and down along with the sliding block 2, the vertical rod 62 is arranged at the bottom end of the sliding groove 13, the reset switch 61 is fixed on the upper end of the vertical rod 62 and located on the movement path of the pressing rod 21, and the reset switch 61 is electrically connected with the motor 51.

[0025] When the tension of the yarn increases and the tensioning wheel 3 and the sliding block 2 move downwards, the pressing rod 21 moves downwards along with the sliding block 2, and since it takes a certain time for the motor 51 to operate, the reset switch 61 can be arranged at the position where the spring 42 at the lower side of the sliding block 2 cannot be compressed any more, so that the pressing rod 21 can be in contact with the reset switch 61 to start the motor 51 before the sliding block 2 moves to the lowest position, reducing the risk that the yarn is broken due to the insufficient increase of the compensation range of the buffering mechanism 4 by the adjusting mechanism 5. When the tension of the yarn decreases, the sliding block 2 moves upwards under the action of the spring 42, so that the pressing rod 21 is separated from the reset switch 61, the reset switch 61 returns to the original state, and the motor 51 stops operating. Meanwhile, a reverse switch for controlling the reverse rotation of the motor 51 can be arranged at the top end of the sliding groove 13, so that the pressing rod 21 can be in contact with the reverse switch after being reset, and the motor 51 is reversed to drive the sliding part 12 to move upwards and reset, and the spring 42 is compressed, so that the amplitude of the yarn swing is reduced when the tension of the yarn is within the normal compensation range of the buffering mechanism 4, and the stability of the yarn conveying is improved.

[0026] Referring to Figure 3 , the vertical rod 62 is arranged at the bottom end of the sliding groove 13 and moves up and down through the threaded structure.

[0027] The vertical rod 62 moves up and down by rotating the vertical rod 62, so as to adjust the position of the reset switch 61 in the sliding groove 13, to adapt to the different maximum tension values that different types of yarns can withstand. The smaller the maximum tension value that the yarn can withstand, the higher the position of the reset switch 61, so that the spring 42 can be compressed in time by the pressing rod 21 pressing the reset switch 61 to realize compensation of the tension. Conversely, the greater the maximum tension value that the yarn can withstand, the lower the position of the reset switch 61, so as to reduce the working frequency of the motor 51, reduce the degree of yarn swing, and reduce the risk of yarn falling off the tensioning wheel 3.

[0028] Referring to Figure 3 , the upper end of the vertical rod 62 is provided with anti-skid lines 63, to reduce the occurrence of slippage when the operator rotates the vertical rod 62, and improve the convenience of rotating the vertical rod 62.
