Description

Technical Field

[0001] This application relates to the field of polyester filament production technology, and in particular to an automatic cutting device for a polyester filament production line. Background Technology

[0002] Polyester filament, also known as polyester filament, is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. Polyester filament is characterized by its resistance to chemicals and frequent washing, reducing fading and discoloration of clothing. Therefore, it is used to manufacture hotel uniforms, stonewashed denim clothing, sportswear, and children's clothing.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] Firstly, when the processed polyester fibers are collected, they are in a relatively taut state, which makes them prone to springing back when cut, thus making subsequent yarn collection more difficult.

[0005] Secondly, when collecting polyester yarn, some of the yarn may be loose, which can easily lead to tangling and knotting during collection, making it more difficult to retrieve and reducing the collection efficiency.

[0006] To address the aforementioned problems, the inventors have proposed an automatic cutting device for polyester filament production lines to solve these issues. Utility Model Content

[0007] In order to improve the problem of polyester filament easily springing back in some existing devices, the purpose of this utility model is to provide an automatic cutting device for polyester filament production line.

[0008] To solve the above problems, this utility model provides the following solution: an automatic cutting device for a polyester filament production line, comprising a plate body, a cutting mechanism and a take-up mechanism fixedly installed on the top surface of the plate body, the take-up mechanism being located on one side of the cutting mechanism, the cutting mechanism comprising a fixed plate, the fixed plate being fixedly installed on the top surface of the plate body, two mirror-distributed baffles fixedly installed on the top surface of the fixed plate, two vertically distributed rotating rollers rotatably installed between the two baffles, a sleeve being rotatably installed on one side of one of the baffles, the sleeve being fitted over the rotating rollers, a support plate being fixedly installed on one side of the inner wall of the two baffles, a servo cylinder being fixedly installed on the top surface of the support plate, and a cutter being fixedly installed on the telescopic end of the servo cylinder.

[0009] Preferably, the take-up mechanism includes multiple support plates, one of which has a servo motor fixedly mounted on its top surface, a rotating rod fixedly mounted on its output end, a first gear and a take-up roller fixedly sleeved on the outer surface of the rotating rod, two upright plates fixedly mounted on the top surface of the plate, a first friction roller and a second friction roller rotatably mounted between the two upright plates, a second gear fixedly mounted on one end of the first friction roller, and the outer surface of the second gear meshing with the first gear.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By setting up a cutting mechanism, when polyester filaments need to be cut, the housing can be used to press the polyester filaments together before cutting, which can prevent the taut polyester filaments from springing back, thereby improving the cutting efficiency of polyester filaments.

[0012] 2. This utility model has a take-up mechanism that can take up polyester filaments. The friction roller that rotates in the opposite direction to the take-up roller can keep the polyester filaments tight during take-up, preventing them from becoming loose and tangled.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-4 As shown, this utility model provides an automatic cutting device for a polyester filament production line, including a plate 1, which is used as a support member. A cutting mechanism 2 and a take-up mechanism 3 are fixedly installed on the top surface of the plate 1. The take-up mechanism 3 is located on one side of the cutting mechanism 2. The cutting mechanism 2 can cut polyester filaments, and the take-up mechanism 3 can take up polyester filaments.

[0021] The cutting mechanism 2 includes a fixed plate 21, which is used as a support. The fixed plate 21 is fixedly installed on the top surface of the plate body 1 so that the fixed plate 21 can support the cutting mechanism 2. Two mirror-distributed baffles 22 are fixedly installed on the top surface of the fixed plate 21. The two baffles 22 serve as limiters and can limit the polyester filaments at the production point.

[0022] Two rotating rollers 27, arranged vertically, are rotatably installed between the two baffles 22. The rotating rollers 27 can rotate to convey the polyester filaments. A housing 28 is rotatably installed on one side of one of the baffles 22. The housing 28 can rotate and is rotatably installed on one side of the baffle 22 via a hinge, so that it rotates on one side of the baffle 22.

[0023] The housing 28 is fitted over the outside of the rotating roller 27. The cross-section of the housing 28 is U-shaped so that it will not affect the rotating roller 27 when it rotates. A pressing pad 20 is fixedly installed on the bottom surface of the housing 28. The pressing pad 20 can press the polyester filaments to fix them.

[0024] One of the baffles 22 has a slot 26 on one side. The slot 26 is rectangular. A retaining plate 29 is slidably installed on one end of the top surface of the casing 28, so that the retaining plate 29 slides on one side of the top surface of the casing 28 and cooperates with the slot 26 to fix the casing 28.

[0025] A support plate 23 is fixedly installed on one side of the inner wall of the two baffles 22. The support plate 23 is used as a support component. A servo cylinder 24 is fixedly installed on the top surface of the support plate 23. The servo cylinder 24 is used as a power source. A cutter 25 is fixedly installed on the telescopic end of the servo cylinder 24. The cutter 25 can cut the polyester filament. The cutter 25 is located between the housing 28 and the first friction roller 38, so that it can be used in conjunction with the housing 28. The housing 28 fixes the polyester filament before cutting.

[0026] The take-up mechanism 3 includes multiple support plates 36, which serve as support components. A servo motor 35 is fixedly mounted on the top surface of one of the support plates 36. The servo motor 35 is used as a power source. A rotating rod 34 is fixedly mounted on the output end of the servo motor 35. The rotating rod 34 is used as a transmission component.

[0027] The outer surface of the rotating rod 34 is fixedly fitted with a first gear 33 and a take-up roller 32, so that the rotating rod 34 drives the first gear 33 and the take-up roller 32 to rotate. The rotating rod 34 is installed with a fixing block 31. The end of the rotating rod 34 away from the servo motor 35 is fitted with the fixing block 31. The fixing block 31 can be disengaged from the rotating rod 34, so that the take-up roller 32 can be removed from the outer surface of the rotating rod 34.

[0028] Two upright plates 361 are fixedly installed on the top surface of the plate 1. The two upright plates 361 are used as support members. A first friction roller 38 and a second friction roller 39 are rotatably installed between the two upright plates 361. The outer surfaces of the first friction roller 38 and the second friction roller 39 are both fixedly fitted with soft sleeves, and the outer surfaces of the two soft sleeves are tightly fitted, so that the first friction roller 38 and the second friction roller 39 rotate through the friction between the soft sleeves, and at the same time, they can rub the polyester yarn.

[0029] A second gear 37 is fixedly mounted on one end of each of the two soft-sleeved first friction rollers 38, and the outer surface of the second gear 37 meshes with the first gear 33. The first gear 33 drives the second gear 37 to rotate, thereby driving the first friction rollers 38 to rotate.

[0030] Working principle: First, the device is installed in a suitable position using plate 1. Then, the produced polyester filament is guided through the two rotating rollers 27 of the cutting mechanism 2 and through the first friction roller 38 and the second friction roller 39, while being wound onto the outer surface of the take-up roller 32.

[0031] Then, the servo motor 35 of the take-up mechanism 3 is started, causing the servo motor 35 to drive the rotating rod 34 to rotate. The rotating rod 34 rotates on the top surface of the support plate 36, and at the same time drives the first gear 33 and the take-up roller 32 to rotate, so that the take-up roller 32 takes up the yarn. At the same time, the first gear 33 drives the second gear 37 to rotate, and the second gear 37 drives the first friction roller 38 to rotate between the two vertical plates 361, so that the first friction roller 38 drives the second friction roller 39 to rotate through the friction of the soft sleeve. The first friction roller 38 and the second friction roller 39 pull the polyester yarn in the opposite direction to the take-up roller 32, thereby straightening the polyester yarn and improving its collection effect. The take-up roller 32 can be removed by using the fixing block 31 to separate from the rotating rod 34.

[0032] Then, when the cutting mechanism 2 is needed to cut the polyester filament, first rotate the housing 28 so that the housing 28 drives the pressing pad 20 to press the polyester filament. Then slide the clamping plate 29 so that the clamping plate 29 is inserted into the clamping groove 26 to fix the housing 28. Then start the servo cylinder 24 on the top surface of the support plate 23. The servo cylinder 24 drives the cutter 25 to move so that the cutter 25 cuts the polyester filament.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
