Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0019] A carding machine strip cutting device includes a processing body 1. A upper support plate 2 is fixedly connected to the upper right position of the processing body 1. A telescopic rod 3 is arranged in the middle position of the upper support plate 2. The movable end of the telescopic rod 3 is fixedly connected with a connecting clamping plate 4. A left support block 6 is fixedly connected to the side position of the connecting clamping plate 4 close to the discharging port of the processing body 1. A first guide rod 7 is inserted into the middle position of the left support block 6. The bottom end of the first guide rod 7 is fixedly connected with a limiting pressing plate 8. The top end of the first guide rod 7 is fixedly connected with a limit joint 10. A right support block 11 is fixedly connected to the side position of the connecting clamping plate 4 away from the left support block 6. A second guide rod 12 is inserted into the middle position of the right support block 11. The bottom of the second guide rod 12 is fixedly connected with a pressure roller 13. The top end of the second guide rod 12 is fixedly connected with a top plate 14.

[0020] As Figure 1 shown, a conveying table 20 is adjacently arranged at the left side position of the processing body 1. An auxiliary support table 5 is fixedly connected to the lower right position of the processing body 1. A discharging supporting roller 19 is adjacently arranged at the side position of the auxiliary support table 5 away from the processing body 1. When the to-be-processed polyester cotton fabric fiber bundle is conveyed out from left to right by the conveyor belt, the discharging supporting roller 19 will play a role in auxiliary guiding and auxiliary supporting.

[0021] As Figure 1 、 Figure 2 and Figure 3As shown, the connecting card plate 4 and the upper supporting plate 2 are arranged parallel to each other vertically. There are a total of 3 telescopic rods 3. The bottom of the connecting card plate 4 is fixedly installed with a blade body 18. The blade body 18 and the discharge supporting roller 19 are arranged opposite to each other vertically. When the device performs the strip cutting operation, the 3 telescopic rods 3 will provide relative driving forces to the entire strip cutting structure; a first spring 9 is sleeved outside the first guide rod 7. The upper and lower ends of the first spring 9 are fixedly connected to the left supporting block 6 and the limiting pressing plate 8 respectively. There is a set of limiting pressing plates 8 in total front and back. The limiting pressing plate 8 and the auxiliary supporting table 5 are arranged opposite to each other vertically. When the limiting pressing plate 8 is pre-pressed to limit the polyester cotton fiber bundle to be processed, the auxiliary supporting table 5 provides a certain auxiliary supporting force from the bottom of the polyester cotton fiber bundle to be processed; the length of the blade body 18 is set to be equal to the length of the pressing roller 13. The upper part of the pressing roller 13 is arranged in a square strip structure. A second spring 15 is sleeved outside the second guide rod 12. The upper and lower ends of the second spring 15 are fixedly connected to the right supporting block 11 and the top plate 14 respectively. The side of the right supporting block 11 away from the connecting card plate 4 is fixedly connected with a side guide rail 16. The inner side of the side guide rail 16 is slidably connected with a side sliding plate 17. The side sliding plate 17 is fixedly connected to the top plate 14. The height difference between the pressing roller 13 and the limiting pressing plate 8 is 5 cm, and the height difference between the pressing roller 13 and the blade body 18 is 5 cm. When the limiting pressing plate 8 and the pressing roller 13 move up and down in sequence and press against the polyester cotton fiber bundle to be processed one after the other, their distributed squeezing actions will play a certain role in relatively tightening and limiting the polyester cotton fiber bundle in a loose state, so that the device can successfully complete a punching process. And when the top plate 14 receives a relative squeezing force to cooperate with the pressing roller 13 to be telescopic, the mutual cooperation between the side sliding plate 17 and the side guide rail 16 will provide a certain guiding and limiting effect to the pressing roller 13.

[0022] Workflow: During the use of the device in the present utility model, the electrical energy comes from an external power supply. When the carding machine strip cutting device needs to be used, as the polyester cotton cloth raw material is conveyed by the conveying table 20, it is gradually fed into the interior of the processing body 1 from left to right for effective carding. The carded polyester cotton cloth fiber bundles arranged in parallel are taken out to the right through the discharge port of the processing body 1. First, under the limiting action of the upper support plate 2, the device will drive the connecting clamping plate 4, the left support block 6, and the right support block 11 to move downward and upward by starting 3 telescopic rods 3. Under the action of the reserved height difference, a set of front and rear limiting pressing plates 8 and pressing rollers 13 will successively press and limit the fiber bundles conveyed out from the right from top to bottom. At this time, under the limiting action of the first guide rod 7 and the limit joint 10 and the limiting action of the second guide rod 12, the top plate 14, the side guide rail 16, and the side sliding plate 17, while the two respectively utilize the elastic and telescopic design composed of the first spring 9 and the second spring 15, without affecting the up and down lifting action of the connecting clamping plate 4 with the blade body 18, after being subjected to the limiting and pressing treatment from left to right, with the auxiliary supporting action of the discharge supporting roller 19, the entire device can use the punching force generated by the rapid up and down movement of the blade body 18 to realize the truncation operation of the fiber bundles.
