Description

Technical Field

[0001] The present invention relates to the technical field of textile manufacturing, and particularly to a high-efficiency cloth cutting device. Background Art

[0002] The cloth cutting device is the core equipment in the processes of greige cloth slitting, finished product cutting, etc., and its performance directly affects production efficiency and product quality. Traditional cloth cutting devices mostly adopt a split structure design, and processes such as winding, cutting, and material collection need to be completed by multiple devices in relay. This not only occupies a large area but also has problems such as poor process connection and frequent manual transfer. Especially in the cloth winding link, although the conventional double-roller pressing mechanism can realize cloth conveying, the forced cloth spreading method of the mechanical pressing roller is likely to cause stretching deformation of elastic fabrics, and longitudinal wrinkles are easily generated due to uneven friction during high-speed operation, resulting in lamination misalignment in the subsequent cutting process. Existing cutting devices mostly rely on manual adjustment of cloth tension, and there is a lack of an active tensioning mechanism during cutting, resulting in burrs at the cut of high-elastic or thin fabrics, making it difficult to meet the strict requirements for cutting accuracy of high-end textiles. In addition, the loading and unloading of the core roller generally adopt pneumatic clamps or manual operations, which have defects such as poor clamping stability and long material change cycle, while traditional unloading mechanisms mostly need to be equipped with independent drive units, which not only increases energy consumption, but also the complex mechanical structure leads to an increase in failure rate and maintenance cost.

An anti-rotation fin is provided at the connection between the clamping rod 702 and the clamping block 703. A first spring 7022 is sleeved on the clamping rod 702 to provide a downward thrust for the clamping block 703 all the time. A clamping head 7031 is horizontally arranged towards the inner side on the clamping block 703. The inner end of the clamping head 7031 is in a chamfered structure and is inserted into the tube cavity of the core roller 9.

The other end of the pull rod 7071 is rotatably connected to the upper end of the corresponding clamping rod 702.

The lower end of the cloth-supporting frame 804 first contacts the cloth and expands outward to tighten the cloth to both sides. The cutting knife 803 contacts the cloth and cooperates with the positioning block 201 to cut the cloth.

[0028] Embodiment 2, on the basis of embodiment 1, a ring-shaped electromagnet 7072 is mounted on the slide 707 at a position corresponding to the magnetic block 7051, and when the cloth collecting and transferring frame 7 is unloaded, it moves to the position of the bracket 202, and a smooth core roller 9 is placed in the bracket 202. When the electromagnet 7072 is energized, the electromagnet 7072 and the magnetic block 7051 are attracted to each other, the second spring 706 is compressed, the electromagnet 7072 is de-energized, the magnetic block 7051 loses its suction, the second spring 706 is reset, and the core roller 9 is clamped and installed.

[0029] The following is a further explanation and description of the functions of each structure in the above content: The cloth rolling frame 1 adopts a parallel arrangement structure of double cloth rolling rollers 102, one of which is driven by a motor 101 to provide active traction for the cloth, and the other cloth rolling roller 102 is used as a driven roller to form a double roller clamping system to ensure the smoothness of cloth transportation. The support roller 103 away from the cloth rolling roller 102 is set at a high position, and the cloth is lifted up and then falls naturally, and the cloth's own gravity is used to achieve unfolding and flattening. This design replaces the traditional pressing roller mechanism, simplifies the structure and reduces the risk of cloth stretching and deformation.

[0030] The alignment block 201 set on the cloth cutting table 2 serves as a cutting reference point, and its internal knife groove forms a precise vertical cutting path with the cutter 803. The arc groove surface design of the bracket 202 (rounded corners R≥3mm at both ends) matches the curvature of the outer wall of the core roller 9, providing stable support for the core roller 9 during the cutting process, and reducing the movement resistance through low-friction surface treatment (Ra≤1.6μm). In particular, the end of the bracket 202 and the inclined disc groove of the cloth receiving disc 3 (inclination angle θ=5°-8°) form a gravity unloading channel, so that the cut core roller 9 can automatically slide into the storage area of ​​the cloth receiving disc 3 along the inclined surface.

[0031] The guide groove 401 extends along both sides of the cloth-breaking guide frame 4. Through the sliding fit between the protrusion 7012 of the end guide 701 and the guide groove 401, the linear movement trajectory of the cloth-receiving and moving frame 7 is constrained. When the cloth-receiving and moving frame 7 drives the core roller 9 to move directly above the support groove 202, the limit switch 403 embedded in the guide groove 401 triggers a signal to control the cloth-receiving cylinder 6 to stop advancing and start the cloth-breaking cylinder 801. When the piston rod of the cloth-receiving cylinder 6 is fully retracted, the magnetic stopper 7051 is squeezed and contacted with the unloading roller guide block 402, forcing the buffer rod 705 to compress the second spring 706. At this time, the clamping rod 702 expands outward to release the core roller 9.

[0032] The T-shaped cloth-receiving and moving frame 7 is initially positioned by embedding the chamfer structure (angle α = 30°) of the clamping head 7031 into the lumen of the core roller 9. The first spring 7022 continuously applies a downward pressure (pre-tightening force F 1 = 15 - 20 N) to ensure that the clamping block 703 is in close contact with the end face of the core roller 9. When the electromagnet 7072 of the sliding seat 707 is energized (working voltage DC24V), a magnetic attraction force (attraction force F 2 ≥ 50 N) is generated with the magnetic stopper 7051, overcoming the elastic force of the second spring 706 to expand the clamping rod 702 outward. At this time, the empty core roller 9 can be loaded; after power-off, the second spring 706 resets (stroke S = 10 mm), and the clamping rod 702 is retracted and clamped through the linkage of the pull rod 7071. The anti-rotation fin design (cross-section is D-shaped) of the buffer rod 705 effectively prevents circumferential deviation during the clamping process.

[0033] When the cloth-breaking cylinder 801 drives the knife holder 802 to press down, the lower end of the cloth-supporting frame 804 first contacts the cloth, and under the combined action of the tension spring 805 and the limit block 806, it expands outward (expansion angle β = 15° - 20°) to laterally tension the cloth on both sides of the cutting point (tension T = 5 - 8 N). The guide rod 807 is made of chrome-plated hard steel and forms a double-column guiding system with the linear bearing on the cloth-breaking frame 8 to ensure that the cutting knife 803 cuts the cloth along a vertical path. In particular, the clearance δ between the cutting edge of the cutting knife 803 and the knife groove of the alignment block 201 is ≤ 0.05 mm, achieving burr-free cutting (applicable to fabrics with a thickness of 0.5 - 3 mm).

[0034] The whole set of equipment realizes the control of the action timing through the controller 5: after the cloth-receiving and moving frame 7 winds the cloth to the set length, the limit switch 403 synchronously triggers the cloth-receiving cylinder 6 to stop and the cloth-breaking cylinder 801 to start, completing a full-automatic cycle of "winding - positioning - cutting - unloading". The efficiency is increased by more than 40% compared with traditional equipment, and the cutting accuracy is stably within the range of ±0.5 mm.

[0035] Working principle: The operator places the hollow core roller 9 on the supporting groove 202 of the cloth-breaking table 2. The controller 5 drives the cloth-receiving cylinder 6 to push the cloth-receiving moving frame 7 to move along the guide groove 401 to directly above the supporting groove 202. At this time, the electromagnet 7072 of the sliding seat 707 is energized to generate a magnetic suction force, adsorbing the magnetic stopper 7051 to compress the second spring 706. The linkage pull rod 7071 drives the clamping rod 702 to expand outwards. The chamfer structure of the clamping head 7031 is aligned with the lumen of the core roller 9 and pressed downwards. The first spring 7022 pushes the clamping block 703 to closely fit with the end face of the core roller 9. Subsequently, the electromagnet 7072 is powered off, and the second spring 706 resets to make the clamping rod 702 retract inwards to lock the core roller 9. The cloth-receiving moving frame 7 carries the core roller 9 back above the cloth-winding rack 1, and the cloth-winding roller 102 is driven by the motor 101 to rotate synchronously with the core roller 9 to realize automatic cloth winding.

[0036] First, the operator winds the front end of the cloth around the high-position supporting roller 103 and then it naturally drops to above the cloth-winding roller 102 and is wound around the core roller 9 between the two cloth-winding rollers 102. After starting the controller 5, the motor 101 drives the active cloth-winding roller 102 to rotate, driving the core roller 9 to rotate and wind the cloth. Under the action of the first spring 7022, it can ensure that the core roller 9 is always in contact with the cloth-winding roller 102 during the winding process, ensuring the smooth progress of the winding.

[0037] When the cloth is wound to the preset length, the cloth-receiving moving frame 7 carries the fully loaded core roller 9 and moves along the guide groove 401 to above the supporting groove 202 of the cloth-breaking table 2. The limit switch 403 in the guide groove 401 triggers a signal, the cloth-receiving cylinder 6 stops advancing and the cloth-breaking cylinder 801 is started. The tool holder 802 of the cloth-breaking frame 8 is vertically pressed down under the guidance of the guide rod 807. The lower end of the cloth-supporting frame 804 first contacts the cloth and expands outwards to an angle of 15° - 20° under the action of the tension spring 805 and the limit block 806, laterally tensioning the cloth on both sides of the cutting point. The cutter 803 then cuts into the tool slot of the alignment block 201 to complete high-precision cutting.

[0038] After cutting is completed, the piston rod of the cloth-receiving cylinder 6 contracts, and the cloth-receiving moving frame 7 carries the cut core roller 9 and moves to above the cloth-receiving tray 3. When the piston rod contracts to the limit position, the magnetic stopper 7051 contacts and presses the buffer rod 705 against the unloading roller guide block 402, forcing the second spring 706 to compress, and the clamping rod 702 expands outwards to release the core roller 9. The core roller 9 slides into the storage area along the inclined trough of the cloth-receiving tray 3. At this time, the cloth-receiving moving frame 7 automatically returns to the supporting groove 202 to load a new core roller 9 and enters the next working cycle.
