Description

Technical Field

[0001] This utility model relates to a fabric cutting device, and more particularly to a warp-knitted fabric cutting device. Background Technology

[0002] To facilitate the transportation of warp-knitted fabrics, manufacturers wind them into rolls of a specific length before selling them as finished products. When making various garments and accessories from warp-knitted fabrics, they need to be cut to the required length. Currently, warp-knitted fabrics are typically cut using a cutting device. This device mainly consists of a cutting platform and a movable cutting blade positioned above it. The cutting platform cuts the fabric at the appropriate location. However, the cutting force during this process can easily cause wrinkles, affecting the quality and precision of the cut. Therefore, existing technology suffers from the problem of easily compromised cutting quality. Utility Model Content

[0003] The purpose of this invention is to provide a warp-knitted fabric cutting device. This invention effectively improves the cutting quality.

[0004] The technical solution of this utility model is as follows: A warp-knitted fabric cutting device includes a frame, a cutting platform above the frame, a cutting seam in the middle of the cutting platform, a lifting cutting mechanism above the cutting seam, a dust collection component below the cutting seam, and lifting pressure plates on the left and right sides of the cutting seam; the lifting cutting mechanism includes a support beam above the cutting seam, a cutting drive component on the support beam, a lifting cylinder below the cutting drive component, a mounting plate below the lifting cylinder, a cutting blade in the middle below the mounting plate, and self-retracting pressure rollers on both sides of the cutting blade below the mounting plate.

[0005] In the aforementioned warp-knitted fabric cutting device, the bottom end of the self-extending pressure roller assembly is located below the cutting blade when it is in the extended state.

[0006] In the aforementioned warp-knitted fabric cutting device, the self-retracting pressure roller assembly includes a telescopic rod fixed to a mounting plate, a spring sleeved on the telescopic rod, a mounting frame at the bottom of the telescopic rod, and a row of pressure rollers on the mounting frame.

[0007] In the aforementioned warp-knitted fabric cutting device, the lifting pressure plate has L-shaped base plates at both ends, and the L-shaped base plates are connected to electric lifting rods.

[0008] Compared with existing technologies, this invention, by setting a lifting cutting mechanism above the cutting platform, lifting pressure plates on both sides of the lifting cutting mechanism, and a dust collection component below the cutting platform, can complete the cutting of warp-knitted fabrics and promptly absorb cutting debris, reducing environmental impact. The lifting pressure plates and self-retracting pressure rollers on both sides of the cutting blade provide double compression of the fabric, effectively preventing wrinkles and misalignment, thus significantly improving cutting quality. In summary, this invention effectively improves cutting quality. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0014] Example. A warp-knitted fabric cutting device, configured as follows: Figure 1-3 As shown, the machine includes a frame 1, a cutting platform 2 on top of the frame 1, a cutting seam 3 in the middle of the cutting platform 2, a lifting cutting mechanism 4 above the cutting seam 3, a dust collection component 5 below the cutting seam 3, and lifting pressure plates 6 on the left and right sides of the cutting seam 3. The lifting cutting mechanism 4 includes a support beam 7 located above the cutting seam 3, a cutting drive component 8 on the support beam 7, a lifting cylinder 9 below the cutting drive component 8, a mounting plate 10 below the lifting cylinder 9, a cutting blade 11 in the middle below the mounting plate 10, and self-retracting pressure roller groups 12 located on both sides of the cutting blade 11 below the mounting plate 10.

[0015] When the self-extending pressure roller assembly 12 is in the extended state, its bottom end is located below the cutting blade 11. It first contacts the fabric to achieve pre-compression, which can ensure that the fabric will not move before and after cutting. It can also effectively protect workers from accidental injury by the cutting blade when not in use.

[0016] The self-retractable pressure roller assembly 12 includes a telescopic rod 121 fixed on the mounting plate 10, a spring 122 sleeved on the telescopic rod 121, a mounting frame 123 at the bottom of the telescopic rod 121, and a row of pressure rollers 124 on the mounting frame 123.

[0017] The lifting pressure plate 6 has L-shaped base plates 13 at both ends, and the L-shaped base plates 13 are connected to electric lifting rods 14.

[0018] The cutting platform is equipped with a fabric rotation mechanism at the feed end, which is used to place rolls of fabric and rotate them for discharge.

[0019] The vacuuming assembly includes a vacuum hood located below the cut seam, and the vacuum hood is connected to a vacuum hose and a vacuum fan.

[0020] The cutting drive component uses a lead screw drive module.

[0021] Preferably, the frame includes a movable frame with casters underneath and a lifting support above it, with the cutting platform fixed above the lifting support. This allows the cutting device to move flexibly to meet different cutting needs.

[0022] The working process of this utility model is as follows: The rolled warp-knitted fabric is placed on the fabric rotating mechanism. The worker moves the end of the fabric to the corresponding position on the right side of the cutting platform according to the actual cutting length. Then, the electric lifting rod drives the lifting pressure plate to descend, applying the first layer of pressure to the warp-knitted fabric. Subsequently, the lifting cylinder drives the mounting plate and corresponding components of the lifting cutting mechanism to descend. The self-retracting pressure rollers first contact the fabric, achieving the second layer of pressure. The lifting cutting mechanism continues to descend until the cutting blade contacts the fabric. The cutting drive component then operates, moving the cutting blade along the fabric cutting direction to complete the cutting. During this movement, the self-retracting pressure rollers always move with the cutting direction, pressing the fabric before and after cutting to prevent misalignment and wrinkles, effectively improving cutting quality. During the cutting process, any debris generated is absorbed by the dust collection component.

[0023] To achieve automatic fabric feeding, fabric feeding mechanisms can be set on the front and rear sides of the cutting platform. The fabric feeding mechanism includes a conveyor belt located on the side of the cutting platform, and a fabric clamping component that moves back and forth on the conveyor belt.

[0024] The fabric clamping assembly includes a clamp fixed to the conveyor belt, a base below the clamp, front and rear drive cylinders on the outside of the base, a bracket at the output end of the front and rear drive cylinders, an upper fixed clamping plate above the bracket, and a clamping telescopic rod and a movable clamping plate below the upper fixed clamping plate; an electromagnet is installed inside the upper fixed clamping plate, and a magnetic sheet is embedded inside the movable clamping plate.

[0025] In its initial state, it is located between the fabric clamping assembly cutting seam feed side and the lifting pressure plate; the cutting platform has a notch on its surface at the initial position of the fabric clamping assembly that cooperates with the movable clamping plate.

[0026] A spring can be installed on the clamping telescopic rod to facilitate the separation of the movable clamping plate from the upper fixed clamping plate.

[0027] The automatic fabric feeding process: The rolled warp-knitted fabric is placed on the fabric rotating mechanism, moving the end of the fabric to the feeding mechanism on the cutting seam side. The feeding mechanism moves the end of the fabric to the corresponding position on the right side of the cutting platform according to the actual cutting length. Then, the electric lifting rod drives the lifting pressure plate to descend, applying the first layer of pressure to the warp-knitted fabric. Subsequently, the lifting cylinder drives the mounting plate and corresponding components of the lifting cutting mechanism to descend. The self-retracting pressure rollers first contact the fabric, achieving the second layer of pressure. The lifting cutting mechanism continues to descend until the cutting blade contacts the fabric. The cutting drive component then operates, moving the cutting blade along the fabric cutting direction to complete the cutting. During this movement, the self-retracting pressure rollers always move along the cutting direction, pressing the fabric before and after cutting to prevent misalignment and wrinkles, effectively improving cutting quality. During the cutting process, any debris generated is absorbed by the dust collection component.

[0028] After a fabric cut is completed, the fabric feeding mechanism continues to move to the right, taking the cut fabric away from the cutting area. The fabric feeding mechanism then releases the cut fabric, and the front and rear drive cylinders of the fabric clamping assembly drive the bracket and corresponding clamping plates to retract outward. Then, driven by the conveyor belt, they return to their initial position. The front and rear drive cylinders then start working, expanding the bracket and corresponding clamping plates inward to above the notch. Then, the electromagnet is de-energized, releasing the movable clamping plate. The movable clamping plate descends to the notch under gravity, waiting for the next clamping and feeding operation.
