Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinets, and in particular to a cutting device for producing automotive interior textile fabrics. Background Technology
[0002] Cutting devices in the production of automotive interior textile fabrics are key equipment for achieving precise fabric processing. They are mainly used to cut layered fabrics into qualified parts according to preset dimensions, and their performance directly affects fabric utilization, processing efficiency, and product precision. However, existing technologies and traditional cutting devices generally suffer from the following technical bottlenecks: First, multi-layered fabrics often have wrinkles and uneven thickness, leading to subsequent cutting dimension deviations. Furthermore, manual finishing is inefficient and inconsistent.
[0003] Secondly, the automation level of the positioning and cutting process is insufficient. Traditional cutting mechanisms require manual resetting after cutting one edge before cutting the other side. This requires two round trips when cutting fabric, which is not only time-consuming but also increases mechanical wear due to frequent resetting. Furthermore, there is a lack of automated equipment to remove the cut fabric; it must be removed manually in a timely manner. If not handled promptly, the stacked fabric will obstruct the transport path, preventing the normal transport of subsequent fabric to be cut and severely impacting production continuity.

A conveyor belt 306 is sleeved on the pair of rotating rollers 303.
[0030] like Figure 3 As shown, the positioning mechanism 4 includes a support frame 401, a servo motor 402 is provided inside the support frame 401, a rotating rod 403 is provided at the output end of the servo motor 402, and a positioning plate 404 is provided on the rotating rod 403.
[0031] like Figures 4-7As shown, the bidirectional cutting mechanism 5 includes a support frame 501. A pair of support frames 501 are connected to the support platform 1. A stator guide rail 502 is provided between the pair of support frames 501. A mover 503 is movably provided on the stator guide rail 502. Two cutting heads 504 are symmetrically arranged below the mover 503. Each cutting head 504 includes a connecting rod 505. A blade clamp 506 is provided on one side of the bottom of the connecting rod 505. A V-shaped blade 507 is provided inside the blade clamp 506. A cutting groove 508 is opened on the support platform 1 below the V-shaped blade 507.
[0032] like Figure 4 , Figure 6 As shown, the tilting table 6 includes a base 601, on which a hinged support structure 602 is provided. The hinged support structure 602 is a pair of intersecting inverted triangular support platforms. Telescopic rods 603 are provided on both sides of the hinged support structure 602. A placement platform 604 is provided on the top of the hinged support structure 602. A hinge block 605 is provided at the bottom of the placement platform 604. A hinge block 606 is provided on the top of the telescopic rods 603. The hinge block 605 and the hinge block 606 are hinged to each other.
[0033] like Figure 4 , Figure 6 As shown, the pressing mechanism 7 includes a motor 701, uprights 702 at both ends of the placement platform 604, a transmission rod 703 at the output end of the motor 701, the transmission rod 703 being movably disposed between a pair of uprights 702, and a flattening push roller 704 on the uprights 702.
[0034] like Figure 8 As shown, the hinged support structure 602 includes an equilateral triangular truncated pyramid 602-1. The bottom of the equilateral triangular truncated pyramid 602-1 is connected to the base 601. An inverted triangular truncated pyramid 602-2 is provided above the equilateral triangular truncated pyramid 602-1. The top of the inverted triangular truncated pyramid 602-2 is connected to the placement platform 604. The equilateral triangular truncated pyramid 602-1 and the inverted triangular truncated pyramid 602-2 intersect each other.
[0035] In practice, the operator places the multi-layered fabric on the front end of the support platform 1. An external programmable logic controller (PLC) starts motor 201 of the flattening mechanism 2 according to a pre-programmed sequence, driving the flattening rollers 207 to roll and flatten the multi-layered fabric. The flattened fabric is then received by the conveyor belt mechanism 3. The PLC controls motor 301 to drive the conveyor belt 307 continuously, conveying it to the tilting fabric table 6. A photoelectric sensor at the front end of the conveyor belt 307 detects the fabric conveying length in real time and feeds the signal back to the PLC. When the fabric reaches the cutting size preset by the user via the PLC, the PLC sends a signal to stop the conveyor belt 307.
[0036] At this time, the pneumatic servo motor 402 of the PLC-controlled positioning mechanism 4 drives the rotating rod 403 to rotate rapidly, causing the positioning plate 404 to press vertically down onto the side of the fabric. Simultaneously, a constant pressure is provided by the control cylinder to fix the fabric edge. After positioning, the PLC activates the stator guide rail 502 and cutting groove 508 of the bidirectional cutting mechanism 5, causing its mover 503 to move along the stator guide rail 502 at a set speed. This drives the cutting heads 504 on both sides to move in the direction of fabric travel. The V-shaped blade 507 cuts into the fabric after the positioning pad 508 presses against it, completing the cutting of one side of the edge. Due to the design of the bidirectional cutting mechanism, the PLC-controlled mover 503 does not need to reset; it can directly move in the opposite direction along the guide rail to simultaneously cut the other side of the fabric edge. A single round trip completes the cutting of two symmetrical pieces of fabric, effectively saving reset time and energy consumption.
[0037] The cut fabric falls onto the placement platform 604 of the tilting table 6 via the conveyor belt 307. A height sensor on the placement platform 604 feeds back the fabric stacking height signal to the PLC. When the preset height is reached, the PLC controls the motor 701 of the pressing mechanism 7 to drive the flattening roller 704 downwards along the upright 702, pushing the stacked fabric towards the discharge end. Simultaneously, the PLC controls the pneumatic telescopic rods 603 on both sides of the hinged support structure 602 to retract synchronously, tilting the placement platform 604 and allowing the fabric to slide along the tilted surface into the next process. After unloading, the PLC controls the telescopic rods 603 to reset, restoring the placement platform 604 to a horizontal position. Then, the conveyor belt 307 continues to transport the next section of fabric to be cut, entering a cyclical operation.
[0038] Throughout the process, the PLC precisely controls key parameters such as pneumatic system pressure and motor speed, ensuring that the pneumatic system pressure remains stable at 50-80 kPa for the positioning cylinder and 0.4-0.6 MPa for the linear motor drive air pressure. The repeatability of the mover 503's positioning accuracy reaches ±0.2 mm, and in conjunction with the positioning plate 404, the cutting size error is ≤ ±1 mm. Simultaneously, the PLC incorporates a safety interlock mechanism: the cutting mechanism is prohibited from starting if the positioning plate 404 is not fully engaged; during the tilting of the fabric tilting table 6, the conveyor belt 307 is automatically locked to prevent misoperation, ensuring the accuracy, energy efficiency, and safety of the entire cutting process.
