Description

Technical Field

[0001] This utility model belongs to the field of seat fabric processing technology, specifically a device for flat cutting the edge of seat fabric. Background Technology

[0002] In the production and processing of seat fabrics, fabric cutting is one of the key steps. Currently, traditional seat fabric cutting methods mostly use manual cutting or simple mechanical cutting equipment. Manual cutting is not only labor-intensive and inefficient, but the operator's skill level and operational stability directly affect the smoothness of the cut edges, easily leading to problems such as rough edges and dimensional deviations, making it difficult to meet the high-precision processing requirements of seat fabrics.

[0003] While existing simple mechanical cutting equipment can improve cutting efficiency to some extent, it still has many shortcomings. On the one hand, most of these devices lack a stable fabric fixing mechanism, making the fabric prone to shifting during the cutting process, resulting in irregular cut edges and affecting the fit of the subsequent seat assembly. On the other hand, the adjustment flexibility of the cutting components is insufficient, making it difficult to adjust the cutting pressure and cutting depth according to seat fabrics of different thicknesses and materials (such as woven fabrics, leather, etc.), easily leading to incomplete cutting or over-cutting that damages the fabric. In addition, the cutting components of traditional equipment have low movement precision, failing to achieve precise cutting along the fabric edge, further reducing the processing quality of the seat fabric.

One end of the lead screw 6 extends to one side of one of the support plates 5 and is connected to a first motor 7. The first motor 7 is installed to the rear side of the crossbeam 3 through a motor seat 8. The external thread of the lead screw 6 is threaded onto the sliding seat 9, which slides within the groove 4. One end of the sliding seat 9 is connected to a mounting plate 10, and the back sides of the mounting plate 10 are connected to first sliders 11. The surface of the crossbeam 3 is symmetrically connected to first slide rails 12, and the first sliders 11 and first slide rails 12 are slidably connected. The sliding cooperation between the first sliders 11 and first slide rails 12 achieves the horizontal movement stability of the mounting plate 10. A top seat 13 is connected to the upper middle part of the mounting plate 10. A second motor 14 is installed on the upper end of the top seat 13.

A second slide rail 19 is symmetrically connected to one end of the mounting plate 10. The second slider 18 and the second slide rail 19 are slidably connected. The sliding cooperation between the second slider 18 and the second slide rail 19 realizes the longitudinal movement stability of the lifting plate 17. A cutting component 20 is connected to one side of the lifting plate 17. A cutting groove 21 is opened at the upper end of the base plate 1. The cutting groove 21 is located directly below the cutting blade 2012. Z-shaped frames 22 are connected to both sides of the upper end of the base plate 1. Cylinders 23 are installed at the lower ends of the two Z-shaped frames 22 to drive the lifting and lowering of the pressure plate 25 to fix the fabric. Clamping seats 24 are connected to the lower ends of the two cylinders 23. The pressure plate 25 is connected to the lower ends of the two clamping seats 24 by bolts. Preferably, the bottom of the pressure plate 25 in this device is provided with a rubber anti-slip pad, which not only enhances the fixing effect, but also avoids damage to the fabric surface. By activating cylinder 23, the piston rod of cylinder 23 extends downward, causing clamp 24 and pressure plate 25 to move downward synchronously until the lower end of pressure plate 25 is in close contact with the fabric surface, thereby fixing the fabric and preventing the fabric from shifting during the cutting process.

[0016] The cutting assembly 20 includes a fixed plate 2001 mounted on the lifting plate 17. An upper U-shaped frame 2002 and a lower U-shaped frame 2003 are connected to the upper and lower sides of one end of the fixed plate 2001, respectively. Two guide posts 2004 are installed between the upper and lower U-shaped frames 2002 and 2003 to guide the movable plate 2006. Limiting sleeves 2005 are fitted onto the lower parts of both guide posts 2004 to limit the movement of the movable plate 2006. The same movable plate 2006 is movably fitted around the two guide posts 2004, allowing it to move up and down outside the guide posts 2004, thereby adjusting the pressure of the cutting blade 2012. Springs 2 are provided on both sides of the upper end of the movable plate 2006. 007, Spring 2007 is sleeved on the outside of guide post 2004. Through the setting of Spring 2007, when the cutter 2012 is cutting the fabric, Spring 2007 provides elastic support for movable plate 2006, so that the cutter 2012 can automatically adjust the cutting pressure according to the thickness of the fabric. The upper middle part of the movable plate 2006 is connected to top plate 2009 through support rod 2008. The lower end of top plate 2009 is equipped with mounting rod 2010.

Cutter 2012 is connected to one side of cutter seat 2011 for cutting fabric.

[0017] Working principle: When in use, first lay the seat fabric to be cut flat on the upper surface of the base plate 1, and align the edge of the fabric to be cut with the upper part of the cutting groove 21; then start the cylinder 23, the piston rod of the cylinder 23 extends downward, driving the clamp 24 and the pressure plate 25 to move down synchronously until the lower end of the pressure plate 25 is in close contact with the fabric surface, thereby fixing the fabric and preventing the fabric from shifting during the cutting process; According to the cutting requirements of the fabric, the first motor 7 is started. The first motor 7 drives the lead screw 6 to rotate around its axis. Since the sliding seat 9 is threadedly connected to the lead screw 6 and the sliding seat 9 is limited to the transverse groove 4, the rotation of the lead screw 6 is converted into the transverse movement of the sliding seat 9 along the transverse groove 4, which in turn drives the mounting plate 10, the lifting plate 17 and the cutting assembly 20 to move laterally until the cutting blade 2012 moves to the starting position of the edge of the fabric to be cut. Next, the second motor 14 is started. The second motor 14 drives the screw 15 to rotate around its axis. The lifting seat 16 moves downward along the axis of the screw 15 under the action of the screw 15 thread, which drives the lifting plate 17 and the cutting assembly 20 to move down synchronously. The cutting blade 2012 moves down and contacts the edge of the fabric to start the cutting operation. During the cutting process, the movable plate 2006 can slide up and down along the guide post 2004, and the spring 2007 provides elastic support for the movable plate 2006, so that the cutter 2012 can automatically adjust the cutting pressure according to the thickness of the fabric to ensure thorough cutting and flat edges; at the same time, the first motor 7 is continuously started to control the cutting component 20 to move laterally along the preset trajectory of the fabric edge to achieve continuous cutting of the entire fabric edge. After cutting is completed, first turn off the second motor 14 and control it to reverse, driving the screw 15 to rotate in the opposite direction, so that the lifting seat 16, the lifting plate 17 and the cutting assembly 20 move up and reset; then turn off the cylinder 23, the piston rod of the cylinder 23 retracts upward, driving the pressure plate 25 to move up, releasing the fixation of the fabric, and finally remove the cut fabric from the base plate 1.
