Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to an automatic cutting mechanism for multi-needle machines. Background Technology

[0002] Multi-needle sewing machines are professional equipment used for sewing textiles and industrial products. Their core function is multi-needle synchronous sewing, supporting composite processes such as flat sewing, gathering, and pleating, and are suitable for various fabrics such as woven and knitted fabrics.

[0003] Currently, multi-needle machines require the fabric to be fed into the machine's working area for processing, and then the processed fabric is fed into the cutting device for cutting and unloading.

Furthermore, the cutting time often varies depending on the process or type of fabric. Continuous fabric feeding causes fabric to accumulate and wrinkle, affecting continuous processing and impacting the overall yield and processing efficiency. Utility Model Content

[0030] A multi-needle machine 4 is set on the surface of the worktable 2;

[0031] The cutting assembly 5 includes a cutting frame 51 and a cutting blade 56. The top of the cutting frame 51 is provided with a second guide rail 52, and a first movable seat 53 is slidably provided on the surface of the second guide rail 52.

[0034] This embodiment provides an automatic cutting mechanism for a multi-needle machine, which includes an adjustment component 3, a multi-needle machine 4, a cutting component 5, a stretching component 6, and a second limiting plate 72. Fabric enters the multi-needle machine 4 after passing through the adjustment component 3 for processing. The height of the lifting seat 32 can be adjusted according to the progress of subsequent processing and cutting work, thereby adjusting the height of the fabric conveyed by the adjustment rod 33. This allows for targeted adjustment of the fabric conveying distance. After processing, the fabric is transferred to one end of the worktable 2. The first cylinder 22 drives the first limiting plate 23 to move downwards, pressing and limiting the fabric to be cut. The second motor 64 adjusts the position of the second moving seat 63, thereby driving the support rod 65 and the base plate 66 to move closer to the fabric. After the fabric end is on the surface of the base plate 66, the third cylinder 69 operates to connect the plate 68 and the clamping mechanism. The plate 67 moves downward to press the end of the fabric against the surface of the base plate 66, and the position of the second moving seat 63 is adjusted to pull the fabric to move, stretching and flattening it. After moving to the required length, the second cylinder 71 works to drive the second limiting plate 72 to move downward to press the fabric against the other side of the cutting area. Then the first motor 54 works to drive the first moving seat 53 and the cutting blade 56 to cut the fabric. The cut fabric can move with the base plate 66 and the clamping plate 67.

[0038] In this embodiment, the second motor 64 can adjust the position of the second movable seat 63, thereby driving the support rod 65 and the base plate 66 to move closer to the fabric. The clamping plate 67 on the top of the base plate 66 can contact and clamp with the first limiting plate 23. Then, the height of the clamping plate 67 can be adjusted to tightly clamp the end of the conveyed fabric. Then, the position of the support rod 65 can be adjusted to move outward. The fabric between the clamping plate 67 and the base plate 66 can be pulled outward. After moving to the required length, the movement stops and the second limiting plate 72 presses and limits the movement before cutting.

[0039] In a further embodiment of this invention, the adjustment component 3 also includes an infrared sensor, which is uniformly disposed on the surface of the support frame 1. The lifting seat 32 is provided with a third motor, which is used to drive the lifting seat 32 to slide on the surface of the first guide rail 31.

[0040] In this embodiment, multiple infrared sensors can detect the speed, length, and position of the fabric conveying. An alarm is also provided on the surface of the support frame 1, which can adjust the height of the fabric conveyed by the adjusting rod 33 according to different fabric conveying conditions. It can also adjust the fabric conveying distance in a targeted manner and provide a reminder when the fabric conveying is too fast or too slow and affects the work.

[0041] In a further embodiment of this invention, a first motor 54 is provided at one end of the second guide rail 52. The first motor 54 is used to drive the second guide rail 52 to slide on the surface of the first movable seat 53. A tool holder 55 is fixedly provided at the bottom of the first movable seat 53. A fourth motor is provided on the outside of the tool holder 55. The output end of the fourth motor is connected to the cutting blade 56 in a transmission connection.

[0042] In this embodiment, the first motor 54 drives the first movable seat 53 to move. During the movement of the first movable seat, the cutter seat 55 at its bottom moves accordingly. At the same time, the fourth motor drives the cutting blade 56 to rotate, and the cutting blade 56 cuts the fabric.

[0043] In a further embodiment of this invention, a second motor 64 is provided at one end of the third guide rail 62. The second motor 64 is used to drive the second movable seat 63 to slide at the bottom of the third guide rail 62. The base plate 66 is provided on the front side of the support rod 65.

[0044] In this embodiment, the second motor 64 can adjust the position of the second movable seat 63, thereby driving the support rod 65 and the base plate 66 to move closer to the fabric. After the end of the fabric is on the surface of the base plate 66, the third cylinder 69 works to move the connecting plate 68 and the clamping plate 67 downwards, pressing the end of the fabric against the surface of the base plate 66. The position of the second movable seat 63 is also adjusted to pull the fabric, stretching it flat and moving it to the required length before cutting. Additionally, infrared sensors and distance sensors are evenly distributed on the outer side of the workbench 2. During fabric transport, the fabric hangs vertically in front of the workbench 2. An alarm, infrared sensors, and distance sensors are also installed on the outer side of the workbench 2. The distance sensor can monitor the length of the passing fabric in real time and stop moving when it reaches the specified length. It can also remind manual adjustment when the fabric moves upward and leaves the monitoring area of ​​the infrared sensor if the conveying speed is too fast, so as to avoid affecting the subsequent cutting work. After the cutting is completed, it continues to move outward to pull the fabric to the top of the support plate 60. The bottom of the support plate 60 is equipped with an electric screw, which can drive the support plate 60 to move up and down. When there is less fabric, the support plate 60 is moved to a higher position, and gradually moves downward during the continuous feeding process, so that the top of the support plate 60 is no higher than the height of the worktable 2.
