Description

Technical Field

[0001] This utility model belongs to the field of polyester filament shearing technology, specifically a shearing machine for processing polyester filaments. Background Technology

[0002] Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer, polyethylene terephthalate, which is produced by esterification or transesterification and polycondensation reaction of purified terephthalic acid or dimethyl terephthalate and ethylene glycol. The fiber is made by spinning and post-processing. When processing polyester filaments, it is necessary to cut the polyester filaments, which requires the use of cutting equipment.

[0003] A search revealed that patent CN221701727U discloses a cutting device for processing polyester filaments. The device includes a mounting plate with a pair of lower support rollers and a pair of upper pressure rollers on its front side. The upper pressure rollers are positioned above the lower support rollers. A cutter is located between the lower support rollers and between the upper pressure rollers. The mounting plate has cutter grooves and two support roller grooves, positioned on either side of the cutter grooves. An adjusting mechanism pushes two cutter sliders to engage, causing the cutters to engage and cut the polyester filament. The ends of the polyester filament are fixed by the lower support rollers and upper pressure rollers. The cut ends are clamped by the lower support rollers and upper pressure rollers, facilitating subsequent rewinding of the polyester filament. The cutting process is also more stable, making the device convenient and practical.

[0004] Analysis of the above technical solutions reveals that although the cut yarn ends are clamped by the lower support roller and the upper pressure roller, the clamped polyester yarn ends still require manual pulling to one side before subsequent winding can begin. Since the operator must pass through the cutting blade during this process, their hands are easily injured, thus reducing the safety of the cutting equipment. Therefore, we provide a polyester yarn processing shearing machine to solve these problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shearing machine for processing polyester filament, comprising an L-shaped support, a U-shaped frame fixedly connected to the middle of the L-shaped support, an electric push rod installed in the middle of the U-shaped frame, a vertical plate fixedly connected to the telescopic end of the electric push rod, a mounting frame fixedly connected to the top of the vertical plate, a mounting plate elastically slidingly disposed inside the mounting frame, a pressing roller rotatably connected to one end of the mounting plate, a wire feeding roller and a motor rotatably connected to the top of the L-shaped support, with the output end of the motor connected to one end of the wire feeding roller, the wire feeding roller and the pressing roller in contact, a shearing mechanism disposed between the L-shaped support and the vertical plate, and a guide roller rotatably connected to the bottom end of the vertical plate.

[0007] Preferably, two second springs are fixedly connected to the inner wall of the mounting frame, and one end of each of the two second springs is fixedly connected to the side of the mounting plate. Two first guide rods are provided through the right side of the mounting frame, and one end of each of the two first guide rods is fixedly connected to the side of the mounting plate.

[0008] Preferably, the shearing mechanism includes a shearing blade and a cutting groove. The cutting groove is formed on the surface of the L-shaped support. The shearing blade is fixed to the surface of the vertical plate and corresponds to the cutting groove. The shearing blade is located in the middle of the U-shaped frame. Tensioning mechanisms for guiding polyester filaments are provided above and below the shearing blade.

[0009] Preferably, the tensioning mechanism includes an extrusion groove and a mounting frame. The extrusion groove is formed on the surface of the L-shaped support. The mounting frame is slidably mounted on the mounting frame. Two third guide rods are provided through the mounting frame, and one end of each third guide rod is fixed to the upright plate. Each third guide rod is fitted with a first spring, and the two ends of the first spring are respectively fixed to the surface of the upright plate and the surface of the mounting frame.

[0017] 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.

[0018] Example 1, such as Figure 1-3As shown, this embodiment proposes a shearing machine for processing polyester filament, including an L-shaped support 1. A U-shaped frame 12 is fixedly connected to the middle of the L-shaped support 1. An electric push rod 13 is installed in the middle of the U-shaped frame 12. A vertical plate 15 is fixedly connected to the telescopic end of the electric push rod 13. Two electric push rods 13 are provided to ensure that the vertical plate 15 can move smoothly. A mounting frame 6 is fixedly connected to the top of the vertical plate 15. A mounting plate 5 is elastically slidably arranged inside the mounting frame 6, so that the mounting plate 5 can have an automatic reset effect within the mounting frame 6. A pressing roller 4 is rotatably connected to one end of the mounting plate 5. A wire feeding roller 2 and a motor 3 are rotatably connected to the top of the L-shaped support 1, and the output end of the motor 3 is connected to one end of the wire feeding roller 2. The wire feeding roller 2 and the pressing roller 4 are in contact, and the polyester filament is passed between the wire feeding roller 2 and the pressing roller 4, and the wire feeding roller 2 and the pressing roller 4 squeeze and contact the polyester filament. Then, the operation of the motor 3 is used to push the polyester filament through the wire feeding roller 2 and the pressing roller 4. This device ensures the normal feeding of polyester filaments. A shearing mechanism is installed between the L-shaped support 1 and the upright plate 15. The upright plate 15 is moved by the operation of the electric push rod 13, which cuts the polyester filaments. During the cutting process, the feeding roller 2 and the extrusion roller 4 keep the polyester filaments pressed and fixed to prevent them from springing back after cutting. The cut polyester filaments are then fed downwards by the motor 3, eliminating the need for manual pulling of the polyester filament ends. This ensures the subsequent winding process and improves the practicality of the device. The bottom of the upright plate 15 is rotatably connected to the guide roller 14. The guide roller 14 ensures that the polyester filaments are ultimately fed out from the right side of the guide roller 14 during feeding, facilitating the subsequent winding process. The machinery, parts, and equipment in this device all adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0019] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0020] like Figure 3 As shown, two second springs 17 are fixed to the inner wall of the mounting frame 6, and one end of each second spring 17 is fixed to the side of the mounting plate 5. Two first guide rods 7 are provided through the right side of the mounting frame 6, and one end of each first guide rod 7 is fixed to the side of the mounting plate 5. With the above structure, the mounting plate 5 can automatically reset after sliding in the mounting frame 6. When the upright plate 15 gradually moves away from the L-shaped support 1, the elastic force of the second spring 17 can push the mounting plate 5 to the left, thereby ensuring that the feeding roller 2 and the extrusion roller 4 are always in contact. When the upright plate 15 drives the mounting frame 6 to move to the left, the mounting plate 5 will slide to the right in the mounting frame 6 and squeeze the second spring 17 until the polyester yarn is cut, then the upright plate 15 moves to the right.

[0021] like Figure 1 and Figure 2 As shown, the shearing mechanism includes a shearing blade 18 and a cutting groove 11. The cutting groove 11 is formed on the surface of the L-shaped support 1. The shearing blade 18 is fixed to the surface of the vertical plate 15 and corresponds to the cutting groove 11. The shearing blade 18 is located in the middle of the U-shaped frame 12. Tensioning mechanisms for guiding polyester filaments are provided above and below the shearing blade 18. With the above structure, when the polyester filament has completed part of the winding, when it needs to be sheared, the vertical plate 15 is moved towards the L-shaped support 1 by the operation of the electric push rod 13, so that the shearing blade 18 gradually approaches the cutting groove 11 and finally the polyester filament is sheared between the cutting groove 11 and the shearing blade 18. During the shearing process, the tensioning mechanism will first squeeze the polyester filament and then tighten both sides of the shearing point of the polyester filament to facilitate smooth cutting.

[0022] like Figure 1 and Figure 2 As shown, the tensioning mechanism includes an extrusion groove 10 and a mounting frame 16. The extrusion groove 10 is formed on the surface of the L-shaped support 1. The mounting frame 16 is slidably mounted on the mounting frame 16. Two third guide rods 20 are passed through the mounting frame 16, and one end of each third guide rod 20 is fixed to the vertical plate 15. Each third guide rod 20 is fitted with a first spring 19, and both ends of the first spring 19 are fixed to the surface of the vertical plate 15 and the surface of the mounting frame 16, respectively. An extrusion roller 21 is rotatably connected to the inner wall of the mounting frame 16, and the extrusion roller 21 is adapted to the extrusion groove 10. The extrusion roller 21 protrudes from the shearing blade 18. When the shearing blade 18 cuts the polyester filament, the extrusion roller 21 will first contact the polyester filament and squeeze it into the extrusion groove 10. The extrusion of the upper and lower extrusion rollers 21 achieves the tensioning effect on the polyester filament, ensuring that the shearing blade 18 can smoothly cut the polyester filament in the cutting groove 11. The setting of the extrusion roller 21 also facilitates the downward conveying of the polyester filament, preventing the polyester filament from accidentally touching the shearing blade 18 during the conveying process. The polyester filament is conveyed downward between the feed roller 2 and the extrusion roller 4, and after being guided by the extrusion roller 21, it is finally delivered from the right side of the guide roller 14.

[0023] like Figure 1 and Figure 2 As shown, two opposing second guide rods 8 are fixedly connected to the surface of the L-shaped support 1, and two opposing positioning blocks 9 are fixedly connected to the upright plate 15. The two second guide rods 8 are slidably disposed in the two positioning blocks 9 respectively. With the above structure, the stability of the upright plate 15 during movement can be ensured, and the upright plate 15 can be prevented from tilting. Thus, the upright plate 15 can slide stably on the second guide rods 8 through the positioning blocks 9, which plays a guiding role.

[0024] The working principle and usage process of this utility model are as follows: First, polyester filament is fed from the left side of the feeding roller 2 and passes between the feeding roller 2 and the extrusion roller 4, allowing the feeding roller 2 and the extrusion roller 4 to extrude the polyester filament. Then, the polyester filament is passed downward through the left side of the extrusion roller 21 and finally fed from the bottom of the guide roller 14 to the right side, thus starting the winding of the polyester filament. When the polyester filament has completed the specified winding, the operation of the motor 3 is stopped. The operation of the electric push rod 13 drives the vertical plate 15 to move, so that the extrusion roller 21 first contacts the polyester filament and extrudes it into the extrusion groove 10. Then, the shearing blade 18 cuts the polyester filament in the cutting groove 11. During the cutting process, the feeding roller 2 and the extrusion roller 4 always compress and fix the polyester filament to prevent it from springing back after cutting. The cut polyester filament continues to be fed downward by the operation of the motor 3, eliminating the need for manual pulling out of the polyester filament end, improving personnel safety, and ensuring the subsequent winding process, thus improving the practicality of the device.
