Description

Technical Field

[0001] This utility model relates to a cutting machine, specifically a cutting machine for garment production. Background Technology

[0002] To manufacture clothing, fabric needs to be cut to a specified length. This process involves stretching the fabric straight and then cutting it to the desired length using a horizontal cutting blade.

[0003] Chinese Patent Publication No. CN113622182A discloses a cutting device for garment production and its processing technology. The device includes a worktable and a conveyor mounted on the worktable for conveying fabric. A cutting device for cutting the fabric is mounted on the worktable. An installation assembly is also provided on the worktable, comprising an installation plate and installation columns on both sides of the conveyor. The installation columns are connected to the worktable. The installation plate slides along the installation columns in the direction towards the conveyor. The cutting device is mounted on the installation plate, and a limiting component for fixing the fabric is provided on the installation plate. The limiting component includes a middle rod and a limiting rod; one end of the middle rod is rotatably connected to the mounting plate, and the other end is rotatably connected to the limiting rod. The limiting rod is set along the conveying direction perpendicular to the conveying component. The middle rod and the mounting plate are provided with a transmission component for driving the limiting rod to rotate. The above-mentioned patent also has some disadvantages. It only has the function of longitudinally tightening the fabric, but it cannot achieve vertical pressing. When a large part of the fabric is cut laterally, the fabric is prone to loosening, which can easily cause unevenness of the cut surface. In order to address the above defects, this invention introduces a tensioning device and a frosted surface to prevent the fabric from slipping during cutting. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a cutting machine for garment production, which effectively solves the problems mentioned in the background art.

[0031] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0032] Example 1, by Figure 1-4 This utility model provides a garment cutting machine, including a base 1, a transverse moving seat 2, electric scissors 3, a sanding platform 4, a tension roller 5, a fabric feeding groove 6, a first support 7, a turntable 8, a positioning mechanism 9, a second support 10, a positioning column 11, a limiting plate 12, a spring 13, a pull handle 14, and a positioning groove 15.

[0033] The base 1 has a horizontally sliding seat 2 connected to its top, and an electric scissors 3 that can move longitudinally for cutting is installed on the horizontally sliding seat 2.

[0034] The sanding platform 4 is fixedly installed in the cutting area at the top center of the base 1;

[0035] A pair of tension rollers 5 are symmetrically arranged at both ends of the top of the sanding platform 4. A cloth channel gap is formed between the tension rollers 5 and the sanding platform 4. A cloth-passing groove 6 is opened in the middle of the tension rollers 5 along the axis.

[0036] The first bracket 7 is arranged in pairs on both sides of the base 1, and its top end is rotatably connected to both ends of the tension roller 5.

[0037] Turntable 8 is coaxially fixed to the end of tension roller 5;

[0038] The positioning mechanism 9 is fixedly installed on the base 1 below the turntable 8.

[0039] Base 1: Base 1 provides a stable support foundation for the entire cutting machine. Its top is designed with a horizontal slide rail to enable smooth horizontal sliding of the horizontal moving seat 2, ensuring flexible adjustment of the cutting position.

[0040] Lateral Moving Seat 2: The lateral moving seat 2 can slide freely on the lateral slide rail of the base 1, and an electric scissors 3 is mounted on it. At the same time, the lateral moving seat 2 is equipped with a longitudinal guide rail mechanism. The electric scissors 3 are driven by a servo motor and can move precisely in the vertical direction along the guide rail to realize the longitudinal cutting action of the fabric.

[0041] Electric Scissors 3: As the core cutting execution component, the electric scissors 3 is powered by a servo motor and can cut fabric quickly and accurately. Through its lateral and longitudinal movement on the lateral moving seat 2, it can perform cutting operations on different parts of the fabric.

[0042] Frosted Platform 4: The frosted platform 4 is fixedly installed in the cutting area at the top center of the base 1. The surface roughness Ra value of the platform is set to 3.2-6.3μm. This rough surface design can effectively increase the friction between the fabric and the platform, preventing the fabric from shifting during the cutting process. At the same time, a negative pressure adsorption hole array is provided around the platform, which can be connected to an external negative pressure device to further firmly adsorb the fabric onto the platform, ensuring the stability of the cutting process.

[0043] Tensioning rollers 5: A pair of tensioning rollers 5 are symmetrically arranged at both ends of the top of the abrasive platform 4, forming a fabric channel gap with the abrasive platform 4 to guide the fabric through. A fabric insertion groove 6 is formed along the axis in the middle of the tensioning rollers 5 to facilitate fabric insertion. The surface of the tensioning rollers 5 is covered with an elastic rubber layer with a Shore hardness of 60-70 HA, which provides good tension to the fabric while preventing damage during the tensioning process.

[0044] First support 7: The first support 7, which is set in pairs, is located on both sides of the base 1. Its top end is rotatably connected to both ends of the tension roller 5, providing stable support for the tension roller 5 and ensuring that the tension roller 5 can rotate flexibly and smoothly guide the fabric.

[0045] Turntable 8: Turntable 8 is coaxially fixed to the end of tension roller 5 and rotates together with tension roller 5. Positioning grooves 15 are evenly provided around the turntable 8 at the positions corresponding to positioning posts 11, which are used to cooperate with positioning mechanism 9 to achieve precise control of the rotation angle of tension roller 5.

[0046] Positioning Mechanism 9: The positioning mechanism 9 is fixedly mounted on the base 1 below the turntable 8, and includes a second bracket 10, a positioning post 11, a limiting plate 12, a spring 13, and a pull handle 14. The second bracket 10 is vertically fixed to the base 1; the positioning post 11 is slidably connected to the top of the second bracket 10, and its end facing the turntable 8 is provided with a limiting plate 12 that engages with the edge of the turntable; the spring 13 is sleeved on the outer periphery of the positioning post 11, and its two ends abut against the limiting plate 12 and the second bracket 10 respectively; the pull handle 14 is fixedly connected to the end of the positioning post 11 away from the limiting plate 12, and the end of the pull handle 14 is provided with anti-slip texture, and its rotation axis is set at an angle of 5-15° with the axis of the positioning post 11, which facilitates the operator's force application. By rotating the pull handle 14, the extension and retraction of the positioning post 11 can be controlled, thereby realizing the engagement or disengagement of the limiting plate 12 with the positioning groove 15 on the turntable 8, thus positioning the rotation angle of the tension roller 5.

[0047] Working Principle: When cutting garment fabric, one end of the fabric to be cut is first introduced into the equipment. The fabric must pass through the threading groove 6 opened along the axis in the middle of the tension roller 5. At this time, the fabric is in the gap of the fabric channel formed between the tension roller 5 and the abrasive platform 4. Since the surface of the tension roller 5 is covered with an elastic rubber layer with a Shore hardness of 60-70HA, this rubber layer will exert a certain pressure on the passing fabric, thereby achieving initial tensioning of the fabric and ensuring that the fabric remains relatively taut in subsequent operations, avoiding the impact of fabric slack on cutting accuracy. Rotating the tension roller 5 can wrap the fabric around it to achieve the purpose of tensioning.

[0048] Depending on the cutting requirements of different garment styles, the angle at which the fabric enters the cutting area may need to be adjusted accordingly. At this time, the operator activates the adjustment function of the positioning mechanism 9 by rotating the pull handle 14. The end of the pull handle 14 has anti-slip textures, and its axis of rotation forms a 5-15° angle with the axis of the positioning column 11, a design that facilitates the operator's application of force. When the pull handle 14 is pulled, the positioning column 11, which is fixedly connected to it, retracts against the elastic force of the spring 13. One end of the positioning column 11 has a limiting plate 12 that engages with the edge of the turntable 8. During the retraction process, the limiting plate 12 disengages from the positioning groove 15 on the turntable 8. At this time, the tension roller 5 can rotate freely, and the operator rotates the tension roller 5 to a suitable angle to meet the fabric infeed angle requirements. After the angle adjustment is completed, release the pull handle 14. Under the restoring force of the spring 13, the positioning post 11 extends and the limiting plate 12 re-locks into the new positioning groove 15 on the turntable 8, thereby accurately positioning the rotation angle of the tension roller 5 and ensuring that the fabric can enter the subsequent cutting area at an angle that meets the cutting requirements.

[0049] After the fabric is fed in and the tension roller angle is positioned, the servo motor of the electric scissors 3 is turned on. The electric scissors 3 is mounted on the transverse moving base 2, which can slide freely on the transverse slide rail at the top of the base 1. The transverse moving base 2 also has a longitudinal guide rail mechanism, allowing the electric scissors 3 to move vertically along this longitudinal guide rail under the drive of the servo motor. By coordinating the transverse movement of the transverse moving base 2 and the longitudinal movement of the electric scissors 3 through the control system, the electric scissors 3 can cut the fabric according to a pre-set cutting path.

[0050] During the cutting process, the frosted platform 4 plays a crucial stabilizing role. Its surface roughness Ra value is set to 3.2-6.3 μm, and this rough surface significantly increases the friction between the fabric and the platform, preventing fabric displacement during cutting. Simultaneously, the negative pressure device connected to the platform's perimeter generates suction through an array of negative pressure adsorption holes, tightly adhering the fabric to the frosted platform 4. This further ensures the fabric's stability during cutting, guaranteeing that the electric scissors 3 can accurately and efficiently cut the fabric, meeting the precision and quality requirements of garment production.

[0051] Beneficial effects: Effectively prevents fabric displacement: The surface roughness Ra value of the frosted platform 4 is 3.2-6.3μm, which increases the friction between the platform and the fabric. In addition, the negative pressure adsorption hole array around the platform is connected to an external negative pressure device, which can tightly adsorb the fabric and effectively prevent fabric displacement during the cutting process, thus ensuring cutting stability.

[0052] Good fabric tension effect: The surface of the tension roller 5 is covered with an elastic rubber layer with a Shore hardness of 60-70HA, which forms a gap with the abrasive platform 4 to create a fabric channel. This generates pressure on the fabric passing through to achieve initial tension. At the same time, rotating the tension roller 5 can further wrap the fabric around it to achieve better tension, preventing the fabric from loosening and affecting the cutting accuracy, and without damaging the fabric.

[0053] Precise tension roller angle adjustment: The positioning mechanism 9 controls the extension and retraction of the positioning column 11 by pulling the handle 14, realizing the engagement or disengagement of the limiting plate 12 with the positioning groove 15 on the turntable 8. This facilitates precise adjustment of the rotation angle of the tension roller 5 to meet the diverse needs of different garment styles for fabric infeed angle. The anti-slip texture at the end of the handle 14 and the design of an angle of 5-15° with the axis of the positioning column 11 facilitate the operator's application of force.
