Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, specifically to a cutting piece positioning mechanism. Background Technology

[0002] In current garment production, the marking of cut pieces is typically done manually. Operators must first create a marking pattern, place it on each piece of fabric, and then mark the marks one by one. To improve the quality of the markings, the pen tip must be rotated during the process to ensure clear markings. This method has the following drawbacks: manual operation is inefficient, time-consuming, and labor-intensive, making it unsuitable for mass production; the quality of the markings is affected by the operator's skill level, resulting in poor consistency; and multiple layers of fabric require layer-by-layer processing, leading to repetitive and labor-intensive work. Therefore, there is an urgent need for equipment that can automatically, efficiently, and uniformly complete multi-point marking of fabric pieces.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a cutting piece positioning mechanism.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a cutting piece positioning mechanism, including a frame, a working platform that can move back and forth on the frame, a cutting piece placement area on the working platform, and several horizontally movable limiting supports surrounding it; a mounting frame that can move up and down on the frame, the mounting frame being located above the working platform, and several detachable positioning pens on the mounting frame.

[0006] With a work platform that can move forward and backward and a limiting support that can move horizontally, it can adapt to cut pieces of different sizes, improving the versatility and flexibility of the equipment; at the same time, the mounting frame drives multiple point pens to move up and down synchronously, achieving efficient and uniform point operation, improving production efficiency and consistency.

[0007] Furthermore, the mounting frame includes a first transverse guide rail and a second transverse guide rail arranged in parallel, with a plurality of first longitudinal guide rails disposed between them. The first longitudinal guide rails can be adjusted left and right along the first transverse guide rails and the second transverse guide rails. The mounting frame adopts a structure of transverse guide rails and left-right adjustable longitudinal guide rails, allowing the dotted pen to move and adjust flexibly in the left and right directions, facilitating quick adjustment of the layout according to the size of the cut pieces and dotted point requirements, and enhancing the adaptability and ease of operation of the equipment.

[0008] Furthermore, one or more of the aforementioned dot-positioning pens are mounted on the first longitudinal guide rail, and the dot-positioning pen can be adjusted by moving back and forth along the first longitudinal guide rail. The dot-positioning pen can be adjusted by moving back and forth on the longitudinal guide rail and supports the installation of one or more pens, further improving the precise control and flexibility of the dot position, adapting to different dot pattern requirements, and reducing the time spent changing tools.

[0009] Furthermore, the work platform is mounted on the frame via a second longitudinal guide rail, enabling it to move back and forth. This movement facilitates the placement, alignment, and removal of cut pieces, simplifying the operation process, improving work efficiency, and making it particularly suitable for continuous operations in large-scale production.

[0010] Furthermore, the working platform is made of ferromagnetic material, and the bottom of the limiting support is equipped with a magnetic sheet, which can be adsorbed onto the working platform and moved horizontally. The use of ferromagnetic material for the working platform and the magnetic attachment for the limiting support ensures its stability and adjustability, simplifies installation and adjustment steps, and improves the accuracy and speed of piece positioning.

[0011] Furthermore, the mounting frame is connected to a linear cylinder, which is fixed to the machine frame. Guide columns are provided on both sides of the mounting frame, and these guide columns are mounted on the machine frame and move up and down. The mounting frame is driven by the linear cylinder and guided by the guide columns to ensure smooth and accurate lifting of the point-positioning pen, improving the reliability and consistency of point-positioning operations. At the same time, the cylinder control enables automated operation, reducing the intensity of manual labor.

[0012] Furthermore, the dot-mapping pen is detachably connected to the mounting bracket via a mounting block. The dot-mapping pen includes an outer cylinder connected to the mounting block, a rotatable and vertically movable pen refill inside the outer cylinder, a spring located at the tail of the pen refill, and a pen tip sleeve fitted over the spring. A spiral-shaped hole is formed in the wall of the outer cylinder, and a rod is inserted into the pen refill, passing through the spiral-shaped hole. The dot-mapping pen's detachable design and spiral-shaped hole structure allow the pen refill to rotate automatically during dot-mapping, simulating manual pen rotation to ensure clear and uniform dot printing and improve dot quality. The spring cushions and protects the pen refill, extending its service life.

[0013] Furthermore, a sensor is installed inside the outer cylinder, located above the pen refill, to detect the pen refill pressure and control the dotting process. The sensor's placement above the pen refill allows for real-time detection of pen refill pressure and control of the dotting process, ensuring consistent pressure across multiple layers of fabric pieces. This prevents unclear or damaged dots due to variations in fabric piece thickness, thus improving the standardization of the dotting process.

[0014] Furthermore, a light grating is provided at the front end of the frame, and the work platform is located between the light gratings. The light gratings are set at the front end of the frame and around the work platform to form a safety protection zone. When a foreign object enters, the equipment will automatically stop operating to prevent injury to the operator and improve the safety and reliability of the equipment.

[0015] Furthermore, the linear cylinder is electrically connected to a foot switch. This connection allows operators to control the operation via foot, freeing their hands for fabric processing, improving ease of operation and efficiency, while reducing the risk of misoperation.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: 1. The movable working platform and limiting support can adapt to different sizes of cut pieces, improving the versatility of the equipment.

[0017] 2. The mounting frame drives multiple point pens to move up and down synchronously, achieving efficient and uniform point operation.

[0018] 3. The point marker is detachable and its position is adjustable, making it easy to maintain and replace, and adapting to different point requirements.

[0019] 4. The pen tip can rotate during the dotting process, which can simulate the action of manually rotating a pen and improve the quality of dotting.

[0020] 5. Sensor control point depth ensures consistent pressure at multiple cutting points.

[0021] 6. The design of the light grating and foot switch improves the safety and convenience of operation. Attached Figure Description
