When the tension is too large through the pressure sensor, the electric cylinder is driven to push the rack and gear to rotate, drive the drive plate to rotate, and adjust the position of the sliding shaft to reduce the tension of the polyester wire.
Effectively avoid the polyester wire being broken due to excessive tension, achieve rapid adjustment, reduce friction and stable delivery, and improve the breakage effect.

[0003] During the processing of anti-tensile polyester yarn, excessive tension may cause the anti-tensile polyester yarn to break, affecting the processing of the anti-tensile polyester yarn. It is necessary to avoid the breakage of the anti-tensile polyester yarn. The existing anti-breakage device for anti-tensile polyester yarn does not have a pressure sensor, and the anti-breakage detection and control effect is poor, and it cannot prevent the anti-tensile polyester yarn from breaking in time. Utility Model Content
[0004] The purpose of the utility model is to provide a tensile polyester yarn anti-breaking device in view of the defects of the prior art, so as to solve the problems raised in the above background technology.

[0006] By adopting the above technical solution, adjustments can be made quickly to prevent the polyester yarn from being broken due to excessive tension.
[0007] Guide rollers are rotatably mounted on the two edges of one side of the mounting frame, and the two guide rollers are respectively arranged close to the diagonal edges of the mounting frame.
[0008] By adopting the above technical solution, the polyester yarn can be easily placed.
[0009] The guide roller and the guide plate are both provided with a plurality of arc grooves, and rollers are rotatably mounted on the arc grooves of the guide plate.
[0010] By adopting the above technical solution, the friction of the polyester yarn is reduced.

[0013] The guide roller and the fixing plate are on the same side of the mounting frame, and the electric cylinder, the rack, the driving plate and the gear are on the other side of the mounting frame.
[0014] By adopting the above technical solution, the polyester yarn can be adjusted when the tension is too large to avoid breaking.
[0015] The beneficial effects of the utility model of the anti-breaking device for tensile polyester yarn are:
[0016] During the traction process of polyester yarn, if the tension is too large, it will be transmitted to the pressure sensor through the roller. At this time, the electric cylinder can be driven to push the rack downward, and the rack pushes the gear to rotate, and the gear synchronously drives the drive plate to rotate. The drive plate causes the drive rods on both sides to swing, so that a set of sliding shafts at a higher position moves downward along the slot, and a set of sliding shafts at a lower position moves upward along the other slot. At this time, the distance between the two sliding shafts is shortened, and the distance between the two rollers is also shortened synchronously, thereby reducing the situation where the polyester yarn tension is too large, and adjustments can be made quickly to avoid the polyester yarn being broken due to excessive tension.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0022] Reference Figure 1-3, a tensile polyester yarn anti-breaking device, comprising a mounting frame 1 and a buffer anti-breaking mechanism mounted on the mounting frame 1, the buffer anti-breaking mechanism comprising a driving rod 3, a fixed plate 4, a guide plate 5, a pressure sensor 7, an electric cylinder 8, a rack 9, a movable rod 10, a driving disk 11, a gear 12 and a sliding shaft 13, the fixed plate 4 is two and slides on two notches of the mounting frame 1 through the sliding shaft 13 respectively, the guide plate 5 is mounted on the fixed plate 4 through the pressure sensor 7, the electric cylinder 8 is mounted on the mounting frame 1, the rack 9 is mounted at the output end of the electric cylinder 8, the other end of the rack 9 slides on the mounting frame 1 through the movable rod 10, the driving disk 11 is rotatably mounted on the mounting frame 1, the gear 12 is fixedly mounted on the driving disk 11, and meshes with the rack 9 for transmission, the driving rod 3 passes through and is fixed on the driving disk 11, and its two ends are slidable through the two sliding shafts 13 respectively;
[0023] The polyester yarn is passed around the bottom of a group of guide rollers 2 at a lower position on one side of the mounting frame 1, passed around the upper side of a group of guide plates 5 at a higher position, and attached to the roller 6. Then, it is passed around the bottom of the lower group of guide plates 5, and then pulled to the group of guide rollers 2 at a higher position, and passed around from above. At this time, the polyester yarn is placed;
[0024] During the traction process of polyester yarn, if the tension is too large, it will be transmitted to the pressure sensor 7 through the roller 6. At this time, the electric cylinder 8 can be driven to push the rack 9 to move downward, and the rack 9 pushes the gear 12 to rotate, and the gear 12 synchronously drives the driving disk 11 to rotate, and the driving disk 11 causes the driving rods 3 on both sides to swing, so that a group of sliding shafts 13 at a higher position move downward along the slot, and a group of sliding shafts 13 at a lower position move upward along the other slot. At this time, the distance between the two sliding shafts 13 is shortened, and the distance between the two rollers 6 is also shortened synchronously, thereby reducing the situation where the tension of the polyester yarn is too large.
[0025] Guide rollers 2 are also rotatably installed at the two edges of one side of the mounting frame 1, and the two guide rollers 2 are respectively arranged close to the diagonals of the mounting frame 1; so that the polyester yarn can be placed on the guide rollers 2 and the guide plate 5, and then the polyester yarn can be adjusted through the buffering and anti-breaking mechanism to avoid the polyester yarn being broken due to excessive tension.
[0026] Both the guide roller 2 and the guide plate 5 are provided with a plurality of arc grooves, and a roller 6 is rotatably installed at the arc grooves of the guide plate 5; the polyester yarn can be placed in the arc grooves of the guide roller 2 and the guide plate 5, so that the polyester yarn can be stably transported and pulled, and the buffering and anti-breaking mechanism can be used to prevent the polyester yarn from being pulled too hard; the guide roller 2 and the fixed plate 4 are on the same side of the mounting frame 1, and the electric cylinder 8, the rack 9, the drive disc 11, and the gear 12 are on the other side of the mounting frame 1, which is convenient for placing the polyester yarn and allows the polyester yarn to be adjusted when the tension is too high to avoid breaking.
[0027] The sliding shafts 13 at the two notches on the mounting frame 1 always remain in the same straight line with the driving disk 11; when the two sliding shafts 13 move to the middle of the notch of the mounting frame 1, the buffering and anti-breaking mechanism reaches the maximum buffering effect on the polyester yarn, and when the two sliding shafts 13 are respectively at the upper and lower ends of the corresponding notches, the buffering and anti-breaking mechanism reaches the minimum buffering effect on the polyester yarn.
[0028] The above-described embodiments merely represent several implementation methods of the present invention.
