Description

Technical Field

[0001] This invention belongs to the technical field of fabric cutting equipment, specifically referring to a fabric cutting device for garment processing. Background Technology

[0002] In the process of garment processing, fabric needs to be cut. Traditional cutting methods require manual cutting, which is not only labor-intensive but also extremely inefficient. Therefore, existing cutting methods usually use fabric cutting equipment. However, during the cutting process, wrinkles in the fabric are common. To avoid the adverse effects of wrinkles on the cutting process, a smoothing mechanism is usually added to eliminate the wrinkles. However, most existing smoothing mechanisms have poor smoothing effects. Therefore, during the cutting process, workers need to constantly supervise and manually smooth out any wrinkles that the smoothing mechanism has not smoothed. This method still requires a lot of manpower.

[0003] Therefore, existing technologies typically employ intelligent cutting equipment to automatically cut fabrics. During cutting, images of the fabric surface are captured by observation devices such as cameras, and the images are then identified to check for wrinkles and smooth them out. This eliminates the need for constant worker assistance. However, existing intelligent cutting equipment often struggles to accurately judge the degree of wrinkles in the fabric, especially during the smoothing process. Misjudging the degree of wrinkles can easily lead to damage from over-smoothing or insufficient smoothing force, resulting in poor cutting results.

[0004] Meanwhile, due to factors such as improper placement and insufficient quantity of lighting equipment, the presence of obstructions, and the reflectivity and translucency of the fabric, the visibility of the collected images of the fabric surface is generally very low, which greatly increases the difficulty of recognition and reduces the accuracy of the recognition results. Traditional image processing algorithms generally have poor processing effects and are difficult to effectively improve the visibility of the images. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a fabric cutting device for garment processing. Addressing the technical problems of existing intelligent cutting equipment that easily damages fabric due to over-flattening or fails to completely eliminate wrinkles due to insufficient flattening force, this solution accurately calculates the degree of fabric wrinkles and performs flattening operations based on the wrinkle degree. This effectively solves the technical problems of existing intelligent cutting equipment that easily damages fabric due to over-flattening or fails to completely eliminate wrinkles due to insufficient flattening force. Furthermore, before calculating the degree of fabric wrinkles, this solution uses an image denoising module and a visibility optimization module in conjunction to improve image visibility, thereby further improving the accuracy of the calculated degree of fabric wrinkles and resulting in better cutting effects.

The visibility optimization module performs contrast enhancement on the denoised fabric image C to obtain an enhanced fabric image D, which is then sent to the wrinkle detection module. The wrinkle detection module processes the enhanced fabric image D to obtain a complete wrinkle image G, which is then sent to the wrinkle region extraction module. The wrinkle region extraction module processes the pixels of the wrinkle region in the complete wrinkle image G to obtain the wrinkle degree DF of the fabric, which is then sent to the wrinkle degree judgment module. The wrinkle degree judgment module has a pre-set wrinkle threshold DP. If DF > DP, the fabric is stretched; if DF ≤ DP, the stretching of the fabric is stopped.

[0153] Example 9, this example is based on the above examples, see reference. Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 Before use, the user lifts the feeding leveling seat 3205 and the discharging leveling seat 3305 upwards respectively, creating gaps between the feeding drive rubber roller 3202 and the feeding leveling rubber roller 3206, and between the discharging drive rubber roller 3302 and the discharging leveling rubber roller 3306. This puts the feeding leveling spring 3207 and the discharging leveling spring 3307 in an elastic compression state. At this time, the user passes one end of the fabric through the gaps between the feeding drive rubber roller 3202 and the feeding leveling rubber roller 3206, and between the discharging drive rubber roller 3302 and the discharging leveling rubber roller 3306. Afterwards, the user releases the feeding leveling seat 3205 and the discharging leveling seat 3305. At this time, under the action of their own gravity and the elastic recovery action of the discharging leveling spring 3307, the feeding leveling seat 3205 and the discharging leveling seat 3305 move downwards and come into contact with the surface of the fabric.

[0154] In use, the controller 4000 controls the image acquisition module 7000, the cutting electric actuator 5002, the conveying drive motor 6001, the auxiliary leveling drive motor 3102, the feeding drive motor 3203, and the discharging drive motor 3303 to operate normally. The specific control process is as follows:

[0155] The image acquisition module 7000 acquires the original image A of the fabric and sends it to the controller 4000 to obtain the fabric wrinkle degree DF. When DF>DP, the feeding leveling electromagnet 3208 and the discharging leveling electromagnet 3308 are energized. The energized feeding leveling electromagnet 3208 and the discharging leveling electromagnet 3308 generate a strong magnetic force and move towards the iron block 1 3209 and the iron block 2 3309 respectively. This drives the feeding drive rubber roller 3202 and the discharging drive rubber roller 3302 to squeeze the feeding leveling rubber roller 3206 and the discharging leveling rubber roller 3306 respectively, so that the fabric is firmly fixed.

[0156] After fixing is completed, the auxiliary leveling drive motor 3102, which is in the starting state, drives a set of auxiliary leveling bidirectional lead screws 3101 located near the auxiliary leveling drive motor 3102 to rotate. The set of auxiliary leveling bidirectional lead screws 3101 located near the auxiliary leveling drive motor 3102 drives a set of auxiliary leveling transmission wheels 3103 located near the auxiliary leveling bidirectional lead screws 3101 to rotate. The set of auxiliary leveling transmission wheels 3103 located near the auxiliary leveling bidirectional lead screws 3101 are connected by the auxiliary leveling transmission belt 310. 4. The transmission drives two sets of auxiliary leveling bidirectional lead screws 3101 to rotate synchronously, thereby driving the feeding leveling component 3200 and the discharging leveling component 3300 to move away from each other. The feeding leveling component 3200 and the discharging leveling component 3300, which move away from each other, stretch the fabric, thereby eliminating wrinkles on the fabric surface. When DF≤DP, the stretching of the fabric is stopped, and the cutting electric push rod 5002 is started. The cutting electric push rod 5002, which is in the started state, drives the cutting scissors 5003 to cut the fabric.

[0157] After cutting, the controller 4000 controls the feeding leveling electromagnet 3208 and the discharging leveling electromagnet 3308 to be de-energized, thereby causing the fabric to be released from the fixed state. The conveyor drive motor 6001 and the discharging drive motor 3303 drive the conveyor belt 6004 and the discharging drive rubber roller 3302 to rotate, thereby sending the cut fabric out of the processing table 2000.

[0158] After the cut fabric is sent out, the conveyor drive motor 6001 and the feed drive motor 3203 drive the conveyor belt 6004 and the discharge drive rubber roller 3302 to rotate, so that the fabric to be cut continues to be fed into the processing table 2000. By repeating the above steps, the fabric cutting operation is realized.

[0159] Compared to existing cutting methods, this solution can effectively remove wrinkles from the fabric surface, and does not require workers to be present to assist during cutting, thus saving labor costs and greatly improving efficiency.
