[0002] In garment production, positioning mechanisms are primarily used to ensure cutting accuracy and efficiency. Precise positioning prevents fabric damage caused by human error, such as avoiding skewing or uneven cuts, thus guaranteeing product quality. Manual cutting and positioning typically involves positioning the fabric with pins or weights before cutting, or pressing it flat with a pressure plate. These methods are time-consuming and labor-intensive, increasing the workload and difficulty for workers.

[0003] A patent search revealed a document titled "A Positioning Mechanism for Clothing Production Cutting" (publication number "CN222154298U"). While this device addresses the aforementioned problem, it fails to properly smooth and position the fabric, leading to localized wrinkling and negatively impacting the cutting performance of the laser cutting machine. Therefore, this invention designs a cutting and positioning mechanism for clothing production to solve these problems. Utility Model Content

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A preferred embodiment of the garment production cutting and positioning mechanism provided by this utility model is as follows: Figures 1 to 4The image shows a cutting and positioning mechanism for garment production, comprising a laser cutting machine body 1, a support 2 fixedly mounted on the top of the laser cutting machine body 1; electric push rods 3 fixedly mounted on the left and right sides of the top of the support 2; a mounting plate 4 fixedly mounted on the bottom of the electric push rods 3; a drive assembly 5 assembled on the outside of the mounting plate 4, the drive assembly 5 being able to smooth the fabric, the drive assembly 5 including a slide 501 slidably mounted on the left and right sides of the bottom of the mounting plate 4; a rotating rod 502 rotatably mounted inside the slide 501, and a rolling sleeve 503 fixedly sleeved on the outside of the rotating rod 502; a motor 504 fixedly mounted on the rear end of the slide 501, the output end of the motor 504 rotatably passing through the slide 501, and the output end of the motor 504 being fixedly connected to the rotating rod 502, the motor 504 being a servo motor, and the motor 504 stopping after rotating half a turn; the output end of the electric push rod 3 slidably passing through the support 2, and the bottom of the output end of the electric push rod 3 being fixedly connected to the top of the mounting plate 4.

[0028] It should be noted that existing cutting and positioning mechanisms for garment production still have certain shortcomings in actual use. They are unable to smooth out the fabric, resulting in wrinkles in some areas of the fabric and affecting the subsequent cutting effect.

[0029] In this embodiment, the operator places the fabric on top of the laser cutting machine body 1, aligning the roller sleeve 503 with the left and right sides of the fabric. Then, the electric push rod 3 is activated, controlling the mounting plate 4, along with the slide 501 and the roller sleeve 503, to move along the direction of the fabric, bringing the roller sleeve 503 into contact with the fabric. Next, the motor 504 is activated. At this time, the left motor 504 rotates clockwise, and the right motor 504 rotates counterclockwise. The motor 504 drives the rotating rod 502 and the roller sleeve 503 to rotate. The tangential force generated by the rotating roller sleeve 503 pulls the left and right ends of the fabric outwards, thus straightening and smoothing the fabric. When the motor 504 stops the roller sleeve 503, the self-locking function of the motor 504 positions the smoothed fabric, ensuring the stability of the subsequent cutting of the fabric by the laser cutting machine body 1. The surface of the roller sleeve 503 is designed with anti-slip textures.

[0030] In a further preferred embodiment of this utility model, a guide sleeve 6 is fixedly provided at the top of the slide 501, a slide rod 7 is slidably connected inside the guide sleeve 6, a connecting plate 8 is fixedly provided at the bottom of the slide rod 7, a ball bearing 9 is rotated at the middle of the bottom end of the connecting plate 8, the bottom surface of the ball bearing 9 is lower than the bottom surface of the slide sleeve 503, a top pin 10 is fixedly provided at the top of the slide rod 7, a pressure sensor 11 is fixedly provided at the top of the guide sleeve 6, the pressure sensor 11 and the top pin 10 correspond to each other, a spring 12 is fixedly provided at the top of the slide rod 7, the end of the spring 12 away from the slide rod 7 is fixedly connected to the guide sleeve 6, the spring 12 is sleeved on the outside of the top pin 10 and the pressure sensor 11, a controller 13 is fixedly provided on the outer wall of the bracket 2, and the controller 13 is connected to the laser cutting machine body 1, the electric push rod 3, the motor 504 and the pressure sensor 11 through wires.

[0031] In this embodiment, when the electric push rod 3 controls the slide 501 to move along the direction of the fabric, the slide 501 drives the guide sleeve 6 together with the connecting plate 8 and the ball bearing 9 to first apply pressure to the fabric. Through the reaction force of the laser cutting machine body 1 and the fabric, the connecting plate 8 controls the slide rod 7 to drive the top pin 10 to move upward along the direction of the guide sleeve 6, and the spring 12 deforms until the top pin 10 applies pressure to the pressure sensor 11, that is, after the pressure sensor 11 detects the pressure, at this time, the bottom surface of the ball bearing 9 is parallel to the bottom surface of the sleeve 503, and the electric push rod 3 stops running, ensuring the stability of the sleeve 503 and the fabric being tightly fitted.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the garment production cutting and positioning mechanism provided by this utility model is as follows: Figures 1 to 4 As shown: The mounting plate 4 is equipped with an adjustment assembly, which can move the roller 503 along the lateral direction of the mounting plate 4. The adjustment assembly includes a slide groove 14 integrally set at the bottom of the mounting plate 4; sliders 15 are slidably set on the left and right sides inside the slide groove 14, and the sliders 15 correspond one-to-one with the slide frame 501, and the sliders 15 and the slide frame 501 are fixedly connected; a connecting rod 16 is rotatably set inside the mounting plate 4, and the axis of the connecting rod 16 is designed to be perpendicular to the axis of the rotating rod 502. The connecting rod 16 is threaded through the slider 15, and the slider 15 on the left side is connected to the connecting rod 16 with a left thread, and the slider 15 on the right side is connected to the connecting rod 16 with a right thread.

[0034] In this embodiment, the operator can rotate the connecting rod 16. Through the threaded transmission design between the connecting rod 16 and the slider 15, the slider 15 drives the slide 501 together with the roller sleeve 503 to move along the direction of the slide groove 14. That is, the two roller sleeves 503 are in a state of moving in opposite directions or towards each other, thereby adjusting the distance between the roller sleeves 503 and ensuring that the roller sleeves 503 can be matched with fabrics of different lengths.

[0035] In summary, this application allows for the smoothing and positioning of fabric before cutting, ensuring the stability of the fabric during subsequent cutting by the laser cutting machine. Through the design of the adjustment function, the displacement of two rollers can be controlled to move in opposite directions, thereby adjusting the distance between the rollers. This allows the rollers to be used with fabrics of different lengths, ensuring effective positioning of fabrics of different sizes.
