Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, and more specifically to a fabric spreading device for knitted fabrics. Background Technology

[0002] Because knitted fabrics are flexible, they are mostly produced and transported in rolls. When using them, these rolls need to be laid flat in multiple layers for easy cutting. Fabric spreading machines lay the rolls of knitted fabric layer by layer on an operating platform according to process requirements. Currently, existing fabric spreading machines, when laying the knitted fabric on the platform, rely on the friction between the fabric layers, which creates wrinkles. This causes the stacked knitted fabric to easily misalign, requiring manual adjustment of the wrinkled areas to keep the fabric flat, reducing work efficiency. To address this, the inventors propose a fabric spreading device for knitted fabrics. This device enables the equidistant and stable stretching and cutting of the knitted fabric, facilitating subsequent processing, eliminating the need for manual intervention, and achieving a high level of automation.

[0003] To prevent misalignment and wrinkles during the fabric spreading process of knitted fabrics, which can affect cutting quality and lead to material waste, Chinese Patent (Authorization Announcement No.: CN112660905A) discloses a fabric spreading machine to prevent misalignment of knitted fabrics. This invention includes a fabric spreading machine, a control device, a cutting device, and a gripping device. A side plate is movably installed inside the fabric spreading machine, and a base plate is fixedly installed inside the side plate. A support spring is fixedly installed at the bottom of the base plate, and a fabric feeding plate is fixedly installed at the top of the support spring. A side frame is fixedly installed at the top of the side plate, and a fabric wheel is movably installed inside the side frame. An insert plate is fixedly installed on the right side of the side frame. A support frame is fixedly installed inside the fabric spreading machine. The control device is fixedly installed inside the fabric spreading machine. The cutting device is movably installed at the bottom of the control device, and the gripping device is fixedly installed at the top of the base plate. This device can spread and cut the fabric back and forth, increasing the efficiency of fabric spreading. While spreading the fabric, it can fix the other end to prevent misalignment and avoid wrinkles.

[0004] This solution still has some shortcomings in application. Because the fabric of the device is flexible and has a certain degree of elasticity, the use of rollers for stretching, while preventing wrinkles, is prone to deviation, resulting in less straight cuts and knitted fabrics that do not meet processing requirements. Therefore, the structure of the knitted fabric stretching device needs to be improved to overcome the aforementioned limitations, making it more suitable for the needs and improving processing quality and efficiency.

[0005] This utility model discloses a fabric spreading device for knitted fabrics, the main purpose of which is to overcome the above-mentioned deficiencies and disadvantages of the prior art.

Next, several clamps are installed from left to right on a fixed frame on the front side of the workbench. Each clamp has grippers; the lower gripper delves into a groove in the cutting table, while the upper gripper is positioned above the knitted fabric. A second cylinder then clamps the end of the knitted fabric and pulls it forward, preventing the fabric from shifting to one side. Combined with the cutting blade, precise cutting is achieved, resulting in high-quality cutting and a high level of automation. Finally, a certain space exists between the clamps and the workbench to accommodate multiple layers of cut knitted fabric, avoiding frequent material handling and making it highly practical. This invention features a novel structure, ingenious design, even fabric pulling, and prevents uneven pulling that affects cutting quality, making it suitable for widespread adoption.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a fabric spreading device for knitted fabric includes a workbench 1, a cutting frame 2 mounted on the rear side of the workbench 1, a cavity 3 mounted in the middle section of the cutting frame 2, a plurality of first cylinders 4 inside the cavity 3, a crossbar 5 mounted on the top of the first cylinders 4, a cutting frame 6 mounted at the end of the crossbar 5, a cutting blade 7 mounted at the end of the cutting frame 6, a cutting table 8 correspondingly mounted below the cutting blade 7, a plurality of grooves 9 mounted on the front side of the cutting table 8, first slide rails 10 mounted on both sides of the workbench 1, a fixing frame 11 mounted between the first slide rails 10, a plurality of clamps 12 mounted on the fixing frame 11, a clamping claw 13 mounted on the front side of the clamping claw 12, the clamping claw 13 corresponding one-to-one with the grooves 9 and can extend into the grooves 9.

[0022] Furthermore, the cutting frame 2 has a built-in fabric drive roller 14.

[0023] Furthermore, a second slide rail 31 is provided on the front side of the cavity 3, and a slider 15 is provided on the rear side of the cutting frame 6. The slider 15 is embedded in the second slide rail 31, and the cutting frame 6 can slide up and down along the second slide rail 31 through the first cylinder 4.

[0024] Furthermore, the second slide rail 31 has a through hole in the middle, and the crossbar 5 passes through the through hole and is connected to the cutting frame 6.

[0025] Furthermore, the clamping device 12 has a built-in second cylinder (not shown in the schematic diagram due to perspective), and the gripper 13 includes an upper gripper 131 and a lower gripper 132. The upper gripper 131 and the lower gripper 132 can be clamped by the second cylinder. The clamping device 12 is provided with an air inlet pipe 17 and an air outlet pipe 18 at the top.

[0026] Furthermore, the middle section of the cutting table 8 is provided with a notch 19, which is directly opposite the cutting blade 7.

[0027] Furthermore, the clamp 12 can slide back and forth along the first slide rail 10 via the fixing frame 11.

[0028] Example: First, the rolled knitted fabric enters the cutting table 8 via the drive roller 14. Simultaneously, the clamp 12 slides along the first slide rail 10 to the cutting table 8 via the fixed frame 11. The lower jaw 132 extends into the groove 9 on the front side of the cutting table 8, and the upper jaw 131 is above the knitted fabric. Then, the upper jaw 131 and lower jaw 132 are driven by the second cylinder to clamp the knitted fabric. After clamping the knitted fabric, the clamp 12 pulls the knitted fabric forward. Since the clamps 12 are arranged in a row on the fixed frame 11, they can pull the fabric simultaneously and synchronously, avoiding deviation. Finally, when the clamp 12 pulls the knitted fabric to the set distance, the first cylinder 4 drives the cutting frame 6 to move downward quickly. The cutting blade 7 at the bottom of the cutting frame 6 quickly cuts the knitted fabric. After completion, the knitted fabric moves forward again via the drive roller 14, and the clamp 12 clamps the knitted fabric again for the next cut. This operation realizes the automated cutting of knitted fabric.
