Description

Technical Field

[0001] This utility model relates to the field of knitted fabric production technology, specifically a cutting device for knitted fabric production. Background Technology

[0002] Cutting is the process of cutting fabric into specific shapes and sizes according to design drawings or patterns. This is a fundamental step in garment making. Through reasonable cutting layout and optimization, fabric can be used to the maximum extent and waste can be reduced. (Existing technology: Authorization Publication No. CN 205975150) U's patent discloses a fabric cutting machine for garment processing, including a platform, support legs, a lifting cylinder, and a crossbeam. A support plate is connected to the piston rod at the upper end of the lifting cylinder, and a horizontal crossbeam is slidably connected to a slide rail. A horizontal lead screw is fixedly connected to the output shaft of a motor, and a slider is threaded onto the lead screw. A knife holder is fixedly connected to the lower side of the slider. A rubber pad is embedded in the upper surface of the platform. A through hole is opened on the upper surface of the platform at the upper end of the inner cavity, and an exhaust fan is connected to the side wall of the inner cavity. During use, the device uses the exhaust fan to generate negative pressure to adsorb the fabric used for knitted fabric production onto the cutting platform. However, for some thick knitted fabrics, the exhaust fan may not provide sufficient adsorption force. When fixing thinner or fragile knitted fabrics, the negative pressure generated by the exhaust fan may damage them, causing the fabric fibers to stretch or deform. Therefore, we propose a cutting device for knitted fabric production. Utility Model Content

The electric push rod 46 is located in the clearance grooves on the front and rear sides of the bottom wall of the placement groove 3. The upper ends of the telescopic ends of two longitudinally adjacent electric push rods 46 are fixedly connected to the lower end of a pressure plate 47. The input ends of the electric push rods 46 are electrically connected to the output ends of the control switch group 2. The fixing mechanism 4 also includes a push plate 48 and a mounting rod 49. The push plate 48 is slidably connected to the bottom wall of the worktable 1. Mounting rods 49 are respectively provided on the left and right sides of the upper end of the push plate 48.

It solves the problem of fiber stretching or deformation of the knitted fabric caused by excessive negative pressure. It has relatively wide applicability and is suitable for knitted fabrics of various materials.

[0017] It also includes a control switch group 2, which is located at the front end of the workbench 1. The input end of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0018] The workbench 1 is rotatably connected to a screw 5 on its lower side. The screw 5 is located between the ends of the two uprights 43 near the center of the workbench 1. The push plate 48 is threaded to the front side of the outer arc surface of the screw 5 through a threaded hole in the middle of its front end. The lower side of the front end of the workbench 1 is equipped with a motor 6. The rear end of the output shaft of the motor 6 is fixedly connected to the front end of the screw 5.

[0019] Specifically: Fixed seats 7 are slidably connected within the sliding grooves on both the front and rear sides of the upper end of the workbench 1. Electric push rods 2 13 are installed in the middle of the left wall of each sliding groove. The right end of the telescopic end of electric push rod 2 13 is fixedly connected to the left end of the adjacent horizontally connected fixed seat 7.

The input ends of both electric push rod 10 and electric push rod 13 are electrically connected to the output end of control switch group 2. By controlling the control switch group 2, electric push rod 13 starts to run and its telescopic end extends, thereby driving the blade 12 to move through the fixed seat 7. After adjusting the position of the blade 12, electric push rod 10 starts to run by controlling the control switch group 2. The telescopic end of electric push rod 10 extends, thereby driving the blade 12 to move downward, and finally the lower end of the blade 12 contacts the upper end of the knitted fabric.

[0020] The connecting seat 8 has an adjusting motor 16 at its rear end, and an adjusting screw 15 is rotatably connected inside the mounting slot. The slider 9 is threaded to the middle of the outer arc surface of the adjusting screw 15 through an adjusting threaded hole at its front end. The front end of the output shaft of the adjusting motor 16 is fixedly connected to the rear end of the adjusting screw 15. The input ends of the adjusting motor 16 are electrically connected to the output ends of the control switch group 2. By controlling the control switch group 2, the adjusting motor 16 starts to run. The output shaft of the adjusting motor 16 drives the adjusting screw 15 to rotate. During the rotation, the adjusting screw 15 drives the slider 9 to move through the threaded connection. The slider 9 then drives the blade 12 to move through the electric push rod 10. Finally, the blade 12 is used to cut the knitted fabric.

[0021] Wherein: A spring 14 is provided between the end of the connecting plate 42 away from the center of the workbench 1 and the inner wall of the workbench 1. The spring 14 is movably connected to the horizontal bar 41 corresponding to the horizontal direction. The thrust generated by the extension of the spring 14 can drive the pressure plate 47 to move and reset through the connecting plate 42.

[0022] The working principle of the cutting device for knitted fabric production provided by this utility model is as follows: During the use of the cutting device for knitted fabric production, the knitted fabric is first laid flat inside the placement groove 3. Then, multiple operators simultaneously pull the four corners of the knitted fabric to flatten it, thereby reducing wrinkles. Afterwards, through the control of the switch group 2, the electric push rod 46 starts to operate, and the telescopic end of the electric push rod 46 shortens, thereby allowing the electric push rod 46 to... This will cause the pressure plate 47 to move downwards, bringing its lower end into contact with the upper surface of the knitted fabric. Then, through the control of switch group 2, motor 6 starts running. The output shaft of motor 6 drives screw 5 to rotate. During the rotation of screw 5, it drives push plate 48 forward through threaded connection. As push plate 48 moves forward, it provides a thrust to adjusting plate 44 through mounting rod 49, causing adjusting plate 44 to drive push rod 45 to rotate around upright rod 43. At this time, adjusting plate 44 will use push rod 45 to... A thrust is applied to the connecting plate 42, causing it to move the pressure plate 47 away from the center of the worktable 1 via the electric push rod 46. The spring 14 contracts, and then, through the control switch group 2, the electric push rod 13 starts operating, extending its telescopic end. This allows the electric push rod 13 to move the blade 12 via the fixed base 7. After adjusting the position of the blade 12, through the control switch group 2, the electric push rod 10 starts operating, extending its telescopic end. This causes the electric push rod 10 to drive the blade 12 downwards, until the lower end of the blade 12 contacts the upper end of the knitted fabric. Then, by controlling the switch group 2, the regulating motor 16 starts running. The output shaft of the regulating motor 16 drives the regulating screw 15 to rotate. During the rotation of the regulating screw 15, it drives the slider 9 to move through the threaded connection. The slider 9 then drives the blade 12 to move through the electric push rod 10. Finally, the blade 12 is used to cut the knitted fabric. It is worth noting that the electric actuator 10 and electric actuator 3 46 disclosed in the above embodiments can be YRJ0905, the electric actuator 2 13 can be DYTFD2000-550 / 45, the motor 6 and the adjusting motor 16 can be ECMA-C20604RS, and the control switch group 2 is provided with control buttons corresponding to the electric actuator 10, electric actuator 2 13, electric actuator 3 46, motor 6 and adjusting motor 16 for controlling their switches.
