Description

Technical Field

[0001] This invention relates to the field of nylon filament cutting technology, specifically to a cutting device for cutting nylon filaments to a fixed length according to the length of a packaged nylon filament. Background Technology

[0002] Nylon filament is a general term for thermoplastic resins containing repeating amide groups (NHCO) in their molecular backbone. It includes aliphatic PA, aliphatic-aromatic PA, and aromatic PA. Among these, aliphatic PA has the most varieties, the largest production volume, and the widest applications; its naming is determined by the specific number of carbon atoms in the synthesized monomer. Nylon filament is commonly used to make combs, toothbrushes, clothes hooks, fan ribs, mesh bag ropes, fruit packaging bags, etc. Nylon filament is mostly produced using extruders.

[0003] During nylon filament production, due to the continuous production of the extruder, the produced nylon filaments need to be wound up using a winding device. After winding, the wound nylon filaments are released and cut to the required length. This process of winding first and then cutting is time-consuming, labor-intensive, and inconvenient. Therefore, the applicant has developed a new technical solution to solve the above-mentioned technical problems during actual production. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a cutting device that cuts nylon filaments to a fixed length according to the packaged length, which has the advantage of directly cutting continuously produced nylon filaments without the need for winding.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a cutting device for cutting nylon filaments to a fixed length according to the packaged length. It includes a base and a feeding conveyor belt arranged side-by-side. The base has an inverted L-shaped fixing plate, and the fixing plate has an inverted U-shaped mounting frame. The mounting frame has a conveying mechanism, and the conveying mechanism is equipped with a clamping mechanism and a cutting mechanism. The conveying mechanism drives the clamping mechanism and the cutting mechanism to move cyclically. As the clamping mechanism and the cutting mechanism move cyclically through the conveying mechanism, the clamping mechanism continuously clamps the continuously produced nylon filaments onto the feeding conveyor belt, and the cutting mechanism cuts the nylon filaments clamped by the clamping mechanism.

[0006] By adopting the above technical solution, during use, one end of the nylon filament produced by the extruder is clamped by a clamping mechanism, and then the clamping mechanism and the cutting mechanism are driven to move cyclically by a conveying mechanism. At this time, the clamping mechanism continuously clamps the continuously produced nylon filament onto the feeding conveyor belt, and the nylon filament is transported by the feeding conveyor belt. During the process of the clamping mechanism continuously clamping the nylon filament onto the feeding conveyor belt, the cutting mechanism cuts the nylon filament clamped by the clamping mechanism. This achieves the purpose of cutting the continuously produced nylon filament directly without the need for winding, saving time and effort, and is simple and convenient to use.

One of the mounting plates is provided with a driving component, which is used to drive one of the sprockets on the two mounting plates to rotate simultaneously. The clamping mechanism and the cutting mechanism are both arranged between the two chains.

Each clamping column corresponds to and contacts each column. Nylon wire located below the two chains passes between two adjacent columns and two adjacent clamping columns. A first pushing mechanism is provided on one of the mounting plates.

The end of the first suspension plate away from the mounting plate is provided with a first push plate horizontally, and the end of the first push plate away from the feeding conveyor belt is provided with a first guide plate that cooperates with the first rotating cylinder.

[0010] Preferably, a plurality of second mounting seats are provided between the two chains, and each second mounting seat is evenly distributed along the circumference of the chain. The second mounting seats are located between two adjacent first mounting seats. The cutting mechanism includes a cutting seat and the cutting seat is mounted on one of the second mounting seats.

Each second cutting blade corresponds to and contacts each first cutting blade. One end of the nylon wire located below the two chains passes between two adjacent first cutting blades and two adjacent second cutting blades. A second pushing mechanism is provided on one of the mounting plates. As the chain drives the first and second mounting seats to move cyclically, the second pushing mechanism is used to push the slide located below the chain to move horizontally on the fixed seat, thereby enabling the first and second cutting blades to cut the nylon filaments.

[0011] Preferably, each of the second mounting seats has an elongated mounting groove along its length. The cutting seat is bolted into the mounting groove of one of the second mounting seats. The cutting seat has an elongated second connecting groove. A second vertical plate is vertically provided on the side of the slide near the cutting seat, and the top of the second vertical plate passes through the second connecting groove and is rotatably connected to a second rotating drum.

[0015] Preferably, the drive unit includes a motor mounted on one of the mounting plates for driving one of the sprockets to rotate, and the two sprockets on the mounting plates are opposite each other and connected by a drive shaft.

[0016] The beneficial effects of this invention are as follows: In use, one end of the nylon filament produced by the extruder is clamped by a clamping mechanism, and then the clamping mechanism and the cutting mechanism are driven to move cyclically by a conveying mechanism. At this time, the clamping mechanism continuously clamps the continuously produced nylon filament onto the feeding conveyor belt, and the nylon filament is conveyed by the feeding conveyor belt.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] A cutting device for cutting nylon filaments to a fixed length according to the packaged filament length, such as... Figure 1 It includes a base 1 and a feeding conveyor belt 2 arranged side by side. The base 1 is provided with an inverted L-shaped fixing plate 3, and the fixing plate 3 is provided with an inverted U-shaped mounting frame 4. The mounting frame 4 is provided with a conveying mechanism. The conveying mechanism is equipped with a clamping mechanism and a cutting mechanism. The conveying mechanism is used to drive the clamping mechanism and the cutting mechanism to move cyclically. When the clamping mechanism and the cutting mechanism move cyclically through the conveying mechanism, the clamping mechanism is used to continuously clamp the continuously produced nylon filaments onto the feeding conveyor belt 2, and the cutting mechanism is used to cut the nylon filaments clamped by the clamping mechanism.

[0022] like Figure 1 In use, one end of the nylon filament produced by the extruder is clamped by the clamping mechanism, and then the clamping mechanism and the cutting mechanism are driven to move cyclically by the conveying mechanism. At this time, the clamping mechanism continuously clamps the continuously produced nylon filament onto the feeding conveyor belt 2. The nylon filament is conveyed by the feeding conveyor belt 2. During the process of the clamping mechanism continuously clamping the nylon filament onto the feeding conveyor belt 2, the cutting mechanism cuts the nylon filament clamped by the clamping mechanism. This achieves the purpose of cutting the continuously produced nylon filament directly without the need for winding, saving time and effort, and is simple and convenient to use.

[0023] like Figure 1 and Figure 2 and Figure 4 The mounting bracket 4 includes two mounting plates 41 arranged opposite each other. The top ends of the two mounting plates 41 are connected by an inverted U-shaped connecting plate 42, which is mounted on the horizontal side of the fixing plate 3. The conveying mechanism includes two sprockets 411 rotatably connected to two mounting plates 41 on opposite sides of each other, and the two sprockets 411 are connected by a chain 412. One of the mounting plates 41 is equipped with a driving component, which drives one of the sprockets 411 on both mounting plates 41 to rotate simultaneously. Both the clamping mechanism and the cutting mechanism are located between the two chains 412. When the clamping mechanism continuously clamps the continuously produced nylon filaments onto the unloading conveyor belt 2, the nylon filaments pass under the space between the two chains 412. The driving component includes a component mounted on one of the mounting plates 41 for driving... One of the sprockets 411 is driven by a motor 413. The two sprockets 411 on the mounting plates 41 are opposite each other and connected by a drive shaft 414. When the motor 413 is turned on, the rotating shaft of the motor 413 drives one of the sprockets 411 to rotate. At this time, the sprocket 411 will drive the remaining sprockets 411 to rotate synchronously through the drive shaft 414 and the chain 412. At this time, the two chains 412 will drive the clamping mechanism and the cutting mechanism to move cyclically along the moving trajectory of the chain 412, so that the clamping mechanism continuously clamps the continuously produced nylon filaments onto the feeding conveyor belt 2. It is simple and convenient to use.

[0024] like Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 9 A plurality of first mounting seats 5 are provided between two chains 412, and each first mounting seat 5 is evenly distributed along the circumference of the chain 412. The clamping mechanism includes clamping members all provided on each of the first mounting seats 5, and each clamping member includes a vertical plate 51 provided on the first mounting seat 5 along the length direction of the first mounting seat 5. A plurality of columns 511 are provided at the end of the vertical plate 51 away from the first mounting seat 5, and each column 511 is spaced apart along the length direction of the vertical plate 51. A sliding plate 512 is horizontally slidably connected to one side of the vertical plate 51, and the sliding plate 512 is away from the first mounting seat 5. One side is provided with several clamping posts 5121, each clamping post 5121 corresponding to and in contact with each upright post 511. Nylon filaments located below the two chains 412 pass between two adjacent upright posts 511 and two adjacent clamping posts 5121. One of the mounting plates 41 is provided with a first pushing mechanism. When the chains 412 drive each first mounting seat 5 to move cyclically, the first pushing mechanism is used to push the slide plate 512 located below the chains 412 to move horizontally on the upright plate 51, thereby enabling the clamping posts 5121 and the upright posts 511 to clamp the nylon filaments (such as...). Figure 7 ); Each first mounting base 5 is provided with a long strip-shaped first connecting groove 52. The slide plate 512 is provided with a first vertical plate 5122 on the side close to the first mounting base 5. The top of the first vertical plate 5122 passes through the first connecting groove 52 and is rotatably connected to the first rotating drum 5123. The side of the first mounting base 5 away from the slide plate 512 is provided with a first protrusion 53. A first tension spring 531 is provided between the first protrusion 53 and the first vertical plate 5122. The first pushing mechanism includes a first suspension plate 54 provided below one side of one of the mounting plates 41. The end of the first suspension plate 54 away from the mounting plate 41 is provided with a first push plate 541 horizontally. The end of the first push plate 541 away from the feeding conveyor belt 2 is provided with a first guide plate 5411 that cooperates with the first rotating drum 5123.

[0025] like Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 9 Two chains 412 drive each first mounting seat 5 to move cyclically along the movement trajectory of the chains 412. When the first mounting seat 5 is above the two chains 412, the upright plate 51 is at the top of the first mounting seat 5. When the first mounting seat 5 is below the two chains 412, the upright plate 51 is at the bottom of the first mounting seat 5. As the chain 412 drives each first mounting seat 5 to move cyclically, the first mounting seat 5 located below and between the two chains 412 gradually approaches the unloading conveyor belt 2. At this time, through the cooperation of the first rotating drum 5123 and the first guide plate 5411, the first rotating drum 5123 can be pushed to drive the first vertical plate 5122 to move in the first connecting groove 52. At this time, the first tension spring 531 is stretched, and the first vertical plate 5122 drives the slide plate 512 to move on the upright plate 51, so that the clamping post 5121 on the slide plate 512 is misaligned with the upright post 511 on the upright plate 51, thereby clamping the nylon thread located below and between the two chains 412 and passing between the two adjacent upright posts 511 and the two adjacent clamping posts 5121 (e.g. Figure 7 At this time, the first rotating drum 5123 moves from the first guide plate 5411 to the first push plate. As the chain 412 drives each first mounting seat 5 to move cyclically, the nylon filament can be pulled close to the feeding conveyor belt 2 by the column 511 and the clamping column 5121 that clamp the nylon filament. As the chain 412 drives each first mounting seat 5 to move cyclically, when the next first mounting seat 5 moves to the area between two chains 412, the nylon thread enters between the two adjacent uprights 511 and the two adjacent clamping posts 5121 on the next first mounting seat 5. As the chain 412 drives each first mounting seat 5 to move cyclically, the above process is repeated. Then, as the chain 412 drives each first mounting seat 5 to move cyclically, when the first rotating drum 5123 separates from the first push plate from the end away from the first guide plate 5411, the stretched first tension spring 531 will push the first vertical plate 5122 to move in the opposite direction in the first connecting groove 52, thereby aligning the clamping posts 5121 with the uprights 51 and releasing the clamping of the nylon thread. At this time, the nylon thread near the feeding conveyor belt 2 will fall onto the feeding conveyor belt 2 due to gravity. Through the above process, the continuously produced nylon thread can be continuously clamped onto the feeding conveyor belt 2, which is simple and convenient to use. The feeding conveyor belt 2 conveys nylon filaments at a speed of F, and the two chains 412 drive each first mounting seat 5 to move cyclically at a speed of F1, where F1 is equal to F.

[0026] like Figure 2 and Figure 3 and Figure 4 and Figure 6 A plurality of second mounting seats 6 are provided between two chains 412, and each second mounting seat 6 is evenly distributed along the circumference of the chain 412. The second mounting seats 6 are located between two adjacent first mounting seats 5. The cutting mechanism includes a cutting seat 61 and the cutting seat 61 is mounted on one of the second mounting seats 6. A fixing seat 611 is provided on the cutting seat 61 along the length direction of the cutting seat 61. A plurality of first cutting blades 6111 are provided on the side of the fixing seat 611 away from the cutting seat 61. The first cutting blades 6111 are spaced apart along the length direction of the fixing seat 611. A slide seat 6112 is horizontally slidably connected to one side of the fixing seat 611. A plurality of second cutting blades 6113 are provided on the side of the slide seat 6112 away from the cutting seat 61. Each second cutting blade 6113 corresponds to and contacts each first cutting blade 6111. One end of a nylon filament located below the two chains 412 passes between two adjacent first cutting blades 6111 and two adjacent second cutting blades 6113 (e.g., Figure 7 One of the mounting plates 41 is provided with a second pushing mechanism. When the chain 412 drives each of the first mounting seats 5 and the second mounting seats 6 to move in a cycle, the second pushing mechanism is used to push the slide 6112 located below the chain 412 to move horizontally on the fixed seat 611, so that the first cutting blade 6111 and the second cutting blade 6113 can cut the nylon filament. Each of the second mounting seats 6 has a long, narrow mounting groove 62 along its length. The cutting seat 61 is bolted into the mounting groove 62 of one of the second mounting seats 6. The cutting seat 61 has a long, narrow second connecting groove 612. A second vertical plate 6114 is vertically mounted on the side of the slide seat 6112 near the cutting seat 61, and the top of the second vertical plate 6114 passes through the second connecting groove 612 and is rotatably connected to a second rotating cylinder 6115. The cutting seat 61 is away from the slide seat 6112. A second protrusion 63 is provided on one side, and a second tension spring 631 is provided between the second protrusion 63 and the second vertical plate 6114. The second pushing mechanism includes a second suspension plate 5412 provided at the top of the first push plate 541, and a second push plate 5413 is provided horizontally at the end of the second suspension plate 5412 away from the first push plate 541. The second push plate 5413 is close to the feeding conveyor belt 2, and a second guide plate 5414 that cooperates with the second rotating drum 6115 is provided at the end of the second push plate 5413 away from the feeding conveyor belt 2.

[0027] like Figure 2 and Figure 3 and Figure 4 and Figure 6 Two chains 412 drive each second mounting seat 6 and first mounting seat 5 to move cyclically along the movement trajectory of the chains 412. When the second mounting seat 6 equipped with the cutting mechanism rotates to the area below the two chains 412, the nylon thread enters between the two adjacent first cutting blades 6111 and the two adjacent second cutting blades 6113. As the chains 412 drive each second mounting seat 6 to move cyclically along the movement trajectory of the chains 412, the first cutting blades 6111 and the second cutting blades 6113 gradually approach the unloading conveyor belt 2. At this time, through the cooperation of the second rotating drum 6115 and the second guide plate 5414, the second rotating drum 6115 can be pushed to drive the second vertical plate 6114 to move in the second connecting groove 612. At this time, the second tension spring 631 is pulled. The second vertical plate 6114 extends, causing the slide 6112 to move on the fixed seat 611, so that the second cutting blade 6113 on the slide 6112 is misaligned with the first cutting blade 6111 on the fixed seat 611, thereby cutting the nylon filament. At this time, the second rotating drum 6115 moves from the second guide plate 5414 to the second push plate. When the chain 412 drives each second mounting seat 6 to move cyclically, and the second rotating drum 6115 separates from the second push plate from the end away from the second guide plate 5414, the stretched second tension spring 631 will push the second vertical plate 6114 to move in the opposite direction in the second connecting groove 612, so that the first cutting blade 6111 and the second cutting blade 6113 are aligned for the next cycle of cutting. When the second cutting blade 6113 and the first cutting blade 6111 cut the nylon filament, the clamping columns 5121 and the upright column 511 on the adjacent sides of the cutting mechanism keep clamping the nylon filament. After the cutting is completed, as the chain 412 drives each of the second mounting seats 6 and the first mounting seat 5 to move cyclically, the first rotating drum 5123 separates from the first push plate 541, thereby releasing the clamping columns 5121 and the upright column 511 from clamping the nylon filament. At this time, the nylon filament that is close to the feeding conveyor belt 2 after cutting will fall onto the feeding conveyor belt 2 due to gravity. Through the above process, the purpose of continuously clamping the continuously produced nylon filament onto the feeding conveyor belt 2 and cutting it can be achieved. It is simple and convenient to use.

[0028] like Figure 1 The number of cutting mechanisms can be two or more. When there are two cutting mechanisms, the cutting seats 61 in the two cutting mechanisms are respectively installed in the mounting slots 62 of the two second mounting seats 6 by bolts. At this time, the two cutting mechanisms are evenly distributed along the circumference of the chain 412. The length of the cut nylon wire can be adjusted by increasing or decreasing the number of cutting mechanisms. It is simple and convenient to use.

[0029] like Figure 2 and Figure 8 An L-shaped cantilever 31 is provided on the side of the fixed plate 3 away from the feeding conveyor belt 2, and a placement plate 311 is provided on the cantilever 31. Several dividing posts 312 are vertically provided at the top of the placement plate 311, and each dividing post 312 is distributed at intervals along the length direction of the placement plate 311. One end of the nylon filament passes between two adjacent dividing posts 312. The nylon filaments can be separated one by one by each dividing post 312, so that the subsequent nylon filaments can enter between two adjacent clamping posts 5121 and two adjacent upright posts 511, as well as between the adjacent first cutting blade 6111 and second cutting blade 6113.

[0030] like Figure 2 and Figure 4 Two U-shaped support frames 415 are provided on the side of the two mounting plates 41 that are close to each other. The upper and lower chains 412 located between the two sprockets 411 are respectively located in the two support frames 415. The chains 412 can be supported by the support frames 415, reducing the possibility of the chains 412 between the two sprockets 411 bending. It is simple and convenient to use.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
