Description

Technical Field

[0001] This utility model belongs to the field of sewing and embroidery equipment, and in particular relates to a fabric rotary cutting and punching device. Background Technology

[0002] In the art of coiled embroidery, after the fabric is laid out, holes need to be punched for positioning. These holes help to fix the position of the fabric and provide a reference for the stitches, making the embroidered pattern more accurate and the lines neater, avoiding deviation or deformation. Punching holes is a key preliminary process to ensure the high-quality presentation of complex coiled embroidery patterns.

[0003] Currently, the mainstream fabric perforation methods on the market include hot cutting and impact perforation devices. Hot cutting mostly uses laser cutting, which has high precision but is prone to sintering edges and emits irritating odors, failing to meet the production standards for specific materials. Impact perforation, on the other hand, relies on a cylinder to drive the punching head to strike the cutter head to complete the perforation. The impact force is large, which can easily cause equipment vibration and generate high noise. Furthermore, the cutter head is prone to dulling after long-term use, affecting the perforation quality. Neither of these two perforation methods can meet the production requirements of high quality, quiet operation, and long lifespan.

[0004] Therefore, there is a particular need for a fabric rotary cutting and punching device to solve the above problems. Utility Model Content

[0005] To overcome the problems of hot cutting perforation producing sintered edges and irritating odors, and impact perforation causing high noise, equipment vibration, and easy dulling of tools, both perforation methods are difficult to meet the requirements of high quality, quiet operation, and long service life. This utility model provides a fabric rotary cutting and perforation device.

[0006] This utility model is achieved through the following technical means: a fabric rotary cutting and punching device, comprising a high-speed rotary motor, a separable fixing ring, a punching fixing bracket, a cylinder, a rotary cutting connecting plate, a rotary cutting blade, and a pin fixing seat. The cylinder is installed on one side of the punching fixing bracket, the rotary cutting connecting plate is fixed to the end of the piston rod of the cylinder, the separable fixing ring is installed on one side of the rotary cutting connecting plate, the high-speed rotary motor is installed inside the separable fixing ring, the rotary cutting blade is fixed to the output shaft of the high-speed rotary motor, and the pin fixing seat is placed below the rotary cutting blade. The rotary cutting blade and the pin fixing seat are coaxially arranged.

[0007] More preferably, it also includes a rotary cutting protective guide, a chip discharge tube, and a discharge ejector pin. The rotary cutting protective guide is fixed to the lower side of the rotary cutting connecting plate. The rotary cutting blade passes through the rotary cutting protective guide and forms a rotational engagement with it. A discharge groove is opened on the outer wall of the rotary cutting blade. The discharge groove is connected to the inside of the rotary cutting blade, and the upper part of the discharge groove extends into the inside of the rotary cutting protective guide. The chip discharge tube is fixed to the rear part of the rotary cutting protective guide and is connected to the inside of the rotary cutting protective guide. The discharge ejector pin is fixed to the center position inside the ejector pin fixing seat.

[0008] More preferably, the discharge ejector pin and the rotary cutter are arranged coaxially.

[0009] More preferably, the inner diameter of the rotary cutter is equal to the outer diameter of the discharge ejector pin.

[0010] More preferably, the lower half of the rotary cutter extending outside the rotary cutting protective guide is at the same height as the discharge ejector pin.

[0011] More preferably, the right side wall of the rotary cutting connecting plate and the left side wall of the cylinder form a sliding fit.

[0012] Beneficial effects: 1. By setting up cylinders, high-speed rotating motors and rotary cutting blades, dynamic cutting replaces high-temperature melting and rigid stamping, avoiding odors, burning and violent vibration, achieving smooth cutting, low-noise operation and long-term service of the blades, and meeting the needs of fine fabric, quiet and long-term operation.

[0013] 2. By setting up rotary cutting protective guides, discharge troughs, discharge chip pipes and discharge pins, waste materials can be sucked up and collected after drilling, preventing waste materials from flying or adhering to the fabric surface and keeping the working environment clean.

[0020] Example: A fabric rotary cutting and punching device, such as Figures 1-5As shown, the device includes a high-speed rotary motor 1, a separable fixing ring 2, a punching fixing bracket 5, a cylinder 6, a rotary cutting connecting plate 7, a rotary cutting blade 8, and an ejector pin fixing seat 10. The cylinder 6 is fixed to the front side of the punching fixing bracket 5 by bolts. The piston rod of the cylinder 6 extends vertically downward. The rotary cutting connecting plate 7 is fixedly connected to the end of the piston rod of the cylinder 6. The right side wall of the rotary cutting connecting plate 7 and the left side wall of the cylinder 6 form a sliding fit to enhance the stability of the rotary cutting connecting plate 7 during movement and reduce shaking and offset. The separable fixing ring 2 is fixed to the left side of the rotary cutting connecting plate 7 by bolts. The high-speed rotary motor 1 is fixed inside the separable fixing ring 2 by bolts. The output shaft of the high-speed rotary motor 1 extends vertically downward. The rotary cutting blade 8 is fixedly connected to the output shaft of the high-speed rotary motor 1. The ejector pin fixing seat 10 is placed below the rotary cutting blade 8. The rotary cutting blade 8 and the ejector pin fixing seat 10 are arranged coaxially.

[0021] like Figures 1-5 As shown, it also includes a rotary cutting protective guide 3, a material discharge tube 4, and a material discharge ejector pin 9. The rotary cutting protective guide 3 is fixedly connected to the lower left side of the rotary cutting connecting plate 7. The rotary cutting blade 8 passes through the rotary cutting protective guide 3 and forms a rotational engagement with it. A material discharge groove 81 is opened on the outer wall of the rotary cutting blade 8. The material discharge groove 81 is connected to the inside of the rotary cutting blade 8, and the upper part of the material discharge groove 81 extends into the inside of the rotary cutting protective guide 3. The material discharge tube 4 is fixedly connected to the rear part of the rotary cutting protective guide 3 and is connected to the inside of the rotary cutting protective guide 3. The material discharge ejector pin 9 is fixedly connected to the center position inside the ejector pin fixing seat 10. The material discharge ejector pin 9 is coaxially arranged with the rotary cutting blade 8. The inner diameter of the rotary cutting blade 8 is equal to the outer diameter of the material discharge ejector pin 9, ensuring that the rotary cutting blade 8 can accurately fit the material discharge ejector pin 9 when it moves downward. The height of the lower half of the rotary cutting blade 8 extending outside the rotary cutting protective guide 3 is equal to the height of the material discharge ejector pin 9, ensuring that the lower half of the rotary cutting blade 8 can completely fit the material discharge ejector pin 9 when it moves downward.

[0022] In use, the operator first installs the punching fixing bracket 5 and the pin fixing seat 10 in the designated positions on the sewing and embroidery equipment, ensuring that the rotary cutter 8 and the discharge pin 9 are coaxially aligned. Then, the vacuum cleaner's suction end is connected to the upper end of the discharge pipe 4, and the vacuum cleaner is started. The fabric is fed between the pin fixing seat 10 and the rotary cutter 8, aligning the fabric's punching position with the rotary cutter 8. Next, the high-speed rotary motor 1 is started, causing its output shaft to drive the rotary cutter 8 to rotate at high speed. Then, the cylinder 6 is started, controlling its piston rod to extend. Through the rotary cutting connecting plate 7, the separating fixing ring 2 and the high-speed rotary motor 1 move downwards synchronously. The rotary cutter 8 then vertically cuts into the fabric, precisely locking onto the discharge pin 9 during its descent, completing the circular cutting action. The cut waste is temporarily disposed of. The material remains at the top of the discharge pin 9 and is covered by the inner wall of the rotary cutter 8. At this time, the vacuum cleaner continues to run, and a negative pressure is formed inside the rotary cutting protective guide 3 through the discharge chip pipe 4. The waste is forcefully sucked in through the discharge groove 81. The waste enters the vacuum cleaner through the rotary cutting protective guide 3 and the discharge chip pipe 4 to realize the waste collection operation. When the piston rod of the cylinder 6 extends to the appropriate length and the rotary cutter 8 completely covers the discharge pin 9, the bottom surface of the rotary cutting protective guide 3 just contacts the top surface of the pin fixing seat 10, forming a mechanical limit. At this time, the piston rod of the cylinder 6 is immediately controlled to retract, so that the rotary cutter 8 moves upward and disengages from the discharge pin 9. The high-speed rotary motor 1 is turned off, and one punching step is completed. Repeat the above steps to continue punching holes in other positions of the fabric.
