Description

Technical Field

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

[0002] Sandwich composite fabric is a functional composite fabric with a three-layer structure. It is named for the sandwich-like shape formed by the middle layer and the top and bottom layers. Its core features are that it combines fluffiness, breathability and structural stability. It is widely used in home furnishing, automotive, sports and other fields. Cutting is a key step in its production and processing, which requires sandwich composite fabric cutting equipment.

[0003] When using existing sandwich composite fabric cutting equipment, it is necessary to stop the machine and replace the corresponding cutting blades when switching between different cutting requirements such as straight cutting and irregular edge treatment. The shutdown process interrupts the operation process, increases the invalid waiting time, and further reduces the overall cutting efficiency, which cannot meet the needs of continuous production. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a sandwich composite fabric cutting device that meets the cutting requirements of straight cutting and irregular edge treatment of sandwich composite fabric without requiring machine downtime for blade replacement.

[0005] The technical solution of this utility model is: a sandwich composite fabric cutting device, including a cutting body, a mounting frame disposed on the upper end of the cutting body along the width direction, and a cutting mechanism rotatably connected to the mounting frame; The cutting mechanism includes a main rotating cylinder rotatably connected to the mounting frame, a forward and reverse rotating motor that drives the main rotating cylinder to rotate, several cutting mounting frames distributed circumferentially on the outer wall of the main rotating cylinder, and cutting blades installed in each of the cutting mounting frames. The cutting and mounting frame has a horizontal mounting plate inside. The horizontal mounting plate is connected to the upper end of the cutting and mounting frame through a miniature hydraulic cylinder. The cutting blade is movably mounted on the horizontal mounting plate at the end opposite to the miniature hydraulic cylinder.

[0006] Furthermore, the cutting body is provided with an adjustment frame that can slide left and right along its side wall. The adjustment frame is connected to the mounting frame by a horizontally installed telescopic connecting rod, and the bottom end of the adjustment frame is connected to a linkage mounting plate by a vertically installed first electric telescopic rod. The bottom end of the linkage mounting plate is provided with pressing vertical plates on the left and right sides.

[0007] Instructions: Once the position of the adjustment frame is determined, activate the first vertically installed electric telescopic rod. This will cause the linkage mounting plate and the bottom pressing vertical plate to move up and down. When moving downwards, the pressing vertical plate can closely fit the fabric surface, firmly fixing the fabric to the worktable of the cutting body. This effectively avoids cutting deviations caused by fabric displacement or wrinkling during the cutting process. It is especially suitable for cutting multi-layered and easily slippery fabrics such as sandwich composite fabrics, providing a stable foundation for subsequent precise cutting.

[0008] Furthermore, the bottom end of the linkage mounting plate is provided with a horizontal sliding groove, the upper end of the pressing vertical plate is slidably connected to the horizontal sliding groove through a sliding block, and the sliding blocks on the two pressing vertical plates are connected by a second electric telescopic rod.

[0009] Explanation: When it is necessary to adjust the distance between the two clamping vertical plates, this can be achieved by controlling the extension and retraction of the second electric telescopic rod. When the second electric telescopic rod extends, it pushes the two sliding blocks to move in opposite directions along the horizontal sliding groove, increasing the distance between the clamping vertical plates to accommodate wider fabrics; when it shortens, it pulls the sliding blocks to move towards each other, decreasing the distance to accommodate narrower fabrics. This structure has a wide range of adaptability and can meet the clamping and fixing requirements of sandwich composite fabrics of different widths without the need to replace special clamping components, thus improving the versatility and ease of use of the device.

[0010] Furthermore, a protective cover is provided on the mounting frame at the upper end of the main rotating cylinder, and the inner wall of the protective cover is provided with a sound-absorbing cotton layer.

[0011] Note: Installing a protective cover on the mounting frame can effectively protect the operator from fabric debris flying outwards during the cutting process, preventing the debris from contaminating the working environment. It also prevents operators from accidentally coming into contact with the cutting mechanism, ensuring operational safety. In addition, the sound-absorbing cotton layer installed on the inner wall of the protective cover can significantly absorb the noise generated by the operation of the cutting mechanism and the cutting of fabric.

[0012] Furthermore, the cutting body is provided with adjusting sliding grooves on the front and rear sides, and the left and right sides of the adjusting frame are respectively slidably connected to the adjusting sliding grooves via sliding strips. The side wall of the adjusting frame is provided with a through-hole that extends into the corresponding sliding strip, and a fastening rod is threadedly connected to the through-hole.

[0013] Instructions: After the position of the adjusting frame is adjusted, rotate the fastening rod clockwise so that its end is tightly against the inner wall of the adjusting sliding groove. The friction will firmly fix the sliding strip in the adjusting sliding groove, thus achieving stable fixation of the adjusting frame. When the position of the adjusting frame needs to be adjusted again, simply rotate the fastening rod counterclockwise so that its end is separated from the inner wall of the adjusting sliding groove. The adjusting frame can then be pushed to move along the adjusting sliding groove. The operation is simple and convenient, and the fixing effect is reliable.

[0014] The beneficial effects of this utility model are: This invention relates to a sandwich composite fabric cutting device. During use, several cutting mounting frames capable of holding various types of cutting blades are installed on the outer wall of the rotatable main rotating cylinder. This satisfies the cutting needs of sandwich composite fabric, such as straight cutting and irregular edge treatment, eliminating the need to stop the machine to change blades, improving operational continuity, reducing downtime, and thus increasing cutting efficiency. By adjusting the extension and retraction of the micro hydraulic cylinder, the cutting depth of the cutting blades can be precisely controlled, adapting to sandwich composite fabrics of different thicknesses (such as single-layer and double-layer composite structures), ensuring thorough cutting without damaging the worktable. Furthermore, considering the multi-layered structure and slippery nature of sandwich composite fabrics, the device utilizes an adjustable clamping vertical plate in conjunction with a horizontal sliding groove and a second electric telescopic rod to precisely adjust the clamping range according to the fabric width, ensuring that the fabric does not shift or wrinkle during cutting.

Detailed Implementation

[0017] Example 1: As Figure 1 As shown, a sandwich composite fabric cutting device includes a cutting body 1, a mounting frame 2 disposed on the upper end of the cutting body 1 along the width direction, and a cutting mechanism 3 rotatably connected to the mounting frame 2. like Figure 2As shown, the cutting mechanism 3 includes a main rotating cylinder 30 rotatably connected to the mounting frame 2, a forward and reverse rotating motor 31 that drives the main rotating cylinder 30 to rotate, several cutting mounting frames 32 distributed circumferentially on the outer wall of the main rotating cylinder 30, and cutting blades 33 installed in each cutting mounting frame 32. The forward and reverse rotating motor 31 and the cutting blades 33 both adopt existing technologies. For example, the forward and reverse rotating motor 31 can be a three-phase asynchronous motor of model Y112M-4, and the cutting blades 33 can be made of existing HRC 62-65 high-speed steel blades, HRC 85-90 carbide blades, stainless steel blades, toothed blades, straight blades, or beveled toothed blades, depending on the existing material and blade shape. The cutting mounting frame 32 has a horizontal mounting plate 320 inside. The horizontal mounting plate 320 is connected to the upper end of the cutting mounting frame 32 via a micro hydraulic cylinder 321. The cutting blade 33 is movably mounted on the horizontal mounting plate 320 at the end opposite to the micro hydraulic cylinder 321. The micro hydraulic cylinder 321 adopts existing technology, such as the MA series micro oil cylinder. like Figure 3 As shown, the cutting body 1 is equipped with an adjustment frame 10 that can slide left and right along its side wall. The adjustment frame 10 is connected to the mounting frame 2 by a horizontally installed telescopic connecting rod 11. The bottom end of the adjustment frame 10 is connected to a linkage mounting plate 13 by a vertically installed first electric telescopic rod 12. The bottom left and right sides of the linkage mounting plate 13 are equipped with pressing vertical plates 14. When the position of the adjustment frame 10 is determined, the vertically installed first electric telescopic rod 12 is activated, which can drive the linkage mounting plate 13 and the pressing vertical plate 14 at the bottom to move up and down. When moving downward, the pressing vertical plate 14 can closely fit the fabric surface and firmly fix the fabric on the worktable of the cutting body 1, effectively avoiding cutting deviations caused by fabric displacement and wrinkling during the cutting process. It is especially suitable for cutting multi-layered and easily sliding fabrics such as sandwich composite fabrics, providing a stable foundation for subsequent accurate cutting. The first electric telescopic rod 12 adopts existing technology, such as a linear electric telescopic rod. The bottom of the linkage mounting plate 13 is provided with a horizontal sliding groove 130. The upper end of the pressing vertical plate 14 is slidably connected to the horizontal sliding groove 130 through a sliding block 131. The sliding blocks 131 on the two pressing vertical plates 14 are connected by a second electric telescopic rod 132. When it is necessary to adjust the distance between the two pressing vertical plates 14, it can be achieved by controlling the extension and retraction of the second electric telescopic rod 132. When the second electric telescopic rod 132 extends, it pushes the two sliding blocks 131 to move in opposite directions along the horizontal sliding groove 130, increasing the distance between the pressing vertical plates 14 to accommodate wider fabrics. When it shortens, it pulls the sliding blocks 131 to move towards each other, reducing the distance to accommodate narrower fabrics. This structure has a wide range of adaptability and can meet the pressing and fixing requirements of sandwich composite fabrics of different widths without the need to replace special pressing parts, thus improving the versatility and ease of use of the device. The second electric telescopic rod 132 adopts existing technology, such as a linear electric telescopic rod. A protective cover 20 is provided on the mounting frame 2 and located at the upper end of the main rotating cylinder 30. The inner wall of the protective cover 20 is provided with a sound-absorbing cotton layer 200. The protective cover 20 on the mounting frame 2 can firstly provide effective protection by blocking the fabric debris generated during the cutting process from flying outward and preventing the debris from contaminating the working environment. At the same time, it can prevent operators from accidentally coming into contact with the cutting mechanism 3 and ensure operational safety. In addition, the sound-absorbing cotton layer 200 on the inner wall of the protective cover 20 can significantly absorb the noise generated when the cutting mechanism 3 is running and when cutting the fabric. The sound-absorbing cotton layer 200 adopts existing technology, such as using sound-absorbing cotton made of mineral wool. like Figure 4 As shown, the cutting body 1 has adjustment sliding grooves 15 on both the front and rear sides. The left and right sides of the adjustment frame 10 are slidably connected to the adjustment sliding grooves 15 by sliding strips 100. The side wall of the adjustment frame 10 has a through-hole 101 that extends into the corresponding sliding strip 100. A fastening rod 102 is threadedly connected to the through-hole 101. After the position of the adjustment frame 10 is adjusted, the fastening rod 102 is rotated clockwise so that its end is tightly abutted against the inner wall of the adjustment sliding groove 15. The sliding strip 100 is firmly fixed in the adjustment sliding groove 15 by friction, thereby achieving stable fixation of the adjustment frame 10. When the position of the adjustment frame 10 needs to be adjusted again, simply rotate the fastening rod 102 counterclockwise so that its end is separated from the inner wall of the adjustment sliding groove 15, and the adjustment frame 10 can be pushed to move along the adjustment sliding groove 15. The operation is simple and convenient, and the fixing effect is reliable.

[0018] The method of using the sandwich composite fabric cutting device in this embodiment includes the following steps: S1. Lay the sandwich composite fabric to be cut flat on the workbench of the cutting body 1. The adjusting frame 10 slides with the adjusting sliding groove 15 through the sliding strip 100, and synchronously drives the telescopic connecting rod 11 and the mounting frame 2 to move as a whole until the pressing vertical plate 14 is in the required pressing position. Then, rotate the fastening rod 102 clockwise so that its end abuts against the inner wall of the adjusting sliding groove 15, and fix the sliding strip 100 by friction, thereby locking the position of the adjusting frame 10 and the mounting frame 2. S2. Start the second electric telescopic rod 132 and adjust the distance between the two pressing vertical plates 14 according to the width of the fabric. When the second electric telescopic rod 132 extends, it pushes the sliding block 131 to move in the opposite direction along the horizontal sliding groove 130 of the linkage mounting plate 13, increasing the distance between the pressing vertical plates 14. When it shortens, it pulls the sliding block 131 to move in opposite directions, decreasing the distance, until the pressing vertical plates 14 match the width of the fabric. S3. The first electric telescopic rod 12 drives the linkage mounting plate 13 and the bottom pressing vertical plate 14 to move down synchronously until the pressing vertical plate 14 is tightly attached to the surface of the fabric, and the fabric is firmly fixed on the worktable. S4. After confirming that the fabric is fixed in place, start the forward and reverse motor 31. The motor drives the main rotating cylinder 30 to rotate stably along the mounting frame 2. The cutting mounting frame 32 on the outer wall of the main rotating cylinder 30 rotates synchronously with the cylinder. When the cutting blade 33 rotates to be close to the top of the fabric, start the micro hydraulic cylinder 321. The output end of the micro hydraulic cylinder 321 pushes the horizontal mounting plate 320 downward, so that the cutting blade 33 installed at the bottom of the horizontal mounting plate 320 contacts and cuts into the sandwich composite fabric. S5. During the cutting process, the protective cover 20 prevents fabric debris from flying outwards, keeping the working environment clean; at the same time, the sound-absorbing cotton layer 200 inside the protective cover 20 absorbs the noise generated by the operation of the main rotating cylinder 30 and the cutting blades 33 cutting the fabric.
