Description

Technical Field

[0001] The utility model relates to the field of slitting machines, in particular to a visual slitting mechanism for fabrics. Background Art

[0002] Fabric slitting refers to the process of cutting or dividing fabrics into strips according to certain specifications and requirements. According to different product designs and production requirements, the fabric is divided into strips of a specific width to facilitate subsequent processing. Through reasonable slitting, fabric waste can be reduced and the material utilization efficiency can be improved. Fabric slitting usually uses professional fabric slitting machines or cutting machines to perform automated or semi-automated slitting operations. This method is highly efficient and accurate and is suitable for large-scale production.

[0003] A slitting machine generally includes a frame, a cutting assembly and a workbench are arranged inside the frame. The cutting assembly includes a rotating shaft, a driving motor and a plurality of cutting tools. The cutting tools are installed on the rotating shaft through fixing seats. By adjusting the tightness of the fixing seats, the fixing seats can move along the surface of the rotating shaft, so as to adjust the distance between the cutting tools. The fixing seats can be fixedly connected to the rotating shaft to prevent the cutting tools from shifting during operation. The driving motor drives the rotating shaft to rotate inside the frame, so that the cutting tools cut the surface of the fabric.

[0004] In the existing publicly disclosed slitting machines, when adjusting the distance between the cutting tools, manual adjustment is usually adopted. After each cutting tool is fixed at a preset position, the cutting and slitting are started. During the cutting and slitting process, since the fabric is moved by a feeding roller, the fabric will shift during the movement. After the fabric shifts, since the cutting tools are fixed, the width of the fabric strips is uneven, and it is easy to have a large size at one end and a small size at the other end, or the width at a certain end in the middle does not meet the standard. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Next, in conjunction with Figures 1-5 a detailed description will be given to a visual slitting mechanism for fabrics of the present utility model:

[0023] A visual striping mechanism for fabrics, comprising a workbench 1, a slitting assembly 2, a light source assembly and an industrial camera 3. The workbench 1, the slitting assembly 2, the light source assembly and the industrial camera 3 are all installed in the whole machine frame. The slitting assembly 2 is aligned with the workbench 1. The two ends of the workbench 1 are respectively a feeding area and a discharging area. The light source assembly and the industrial camera 3 are both aligned with the feeding area. The slitting assembly 2 includes a support cross beam 201, a rack 202, a servo steering gear 203, a gear 204, a tool holder 205 and a circular blade 206. Side support plates 4 are arranged at both ends of the support cross beam 201. A protective cover 5 for blocking dust is arranged between the two side support plates 4. The side support plates 4 are connected to the whole machine frame. The industrial camera 3 is connected to the whole machine frame through a connecting column 6. An installation groove is arranged on the surface of the connecting column 6. An installation plate is arranged on the industrial camera 3. The installation plate is connected to the connecting column 6 through bolts. After loosening the bolts, the position of the industrial camera 3 can be adjusted. The light source assembly includes a top light source 7 and side light sources 8. There are two side light sources 8, which are symmetrically arranged on both sides of the feeding area. The housing of the side light source 8 is connected to the whole machine frame. The top light source 7 is installed at the top of the connecting column 6 through a connecting plate. The top light source 7 and the side light sources 8 are used to illuminate the fabric, making the recognition of the industrial camera 3 more accurate.

[0024] There are eighteen servo steering machines 203, gears 204, knife seats 205 and circular blades 206, two support beams 201 and three racks 202, two support beams 201 are arranged above the workbench 1, and racks 202 are arranged on two support beams 201 respectively, wherein two racks 202 are installed on the same support beam 201, a linear slide rail 207 is arranged on the support beam 201, and a slider 208 is arranged on the knife seat 205. The block 208 is slidably connected with the linear slide 207, and the knife seat 205 can be translated along the surface of the linear slide 207 through the slider 208. The linear slide 207 and the rack 202 are parallel to each other. The twelve knife seats 205 are divided into two groups and are respectively installed on the supporting beam 201 through two linear slides 207. The circular blades 206 are respectively arranged at one end of the eighteen knife seats 205 close to the workbench 1, and the servo steering motors 203 are respectively installed at one end of the knife seats 205 away from the circular blades 206. The wheels 204 are respectively connected to the output shafts of the eighteen servo actuators 203 in a transmission manner, and the eighteen gears 204 are all meshed with the rack 202. The gears 204 and the rack 202 are both helical gear structures, which reduce the backlash between the gears 204 and the rack 202, have the advantages of smooth transmission, high precision, low impact vibration and noise, and allow the gears 204 to have a certain elastic deformation during rotation. The eighteen servo actuators 203 can work independently, and the rack 202 and the supporting beam 201 are parallel to the side of the workbench 1 close to the slitting component 2. The industrial camera 3 and the eighteen servo actuators 203 exchange data through the controller. An elastic knife rod 209 is provided at one end of the knife seat 205 close to the circular blade 206, and the circular blade 206 is rotatably installed on the end of the elastic knife rod 209 away from the knife seat 205, ensuring that the blade of the circular blade 206 can press the surface of the workbench 1 to prevent a gap from being generated between the circular blade 206 and the workbench 1, so that the cloth cannot be completely cut.

[0025] A visual striping mechanism for cloth in the present embodiment is provided with a slitting component 2. The cloth is visually positioned by an industrial camera 3. The slitting component 2 can be automatically adjusted. When the servo actuator 203 rotates, the gear 204 and the rack 202 are engaged, so that the knife seat 205 moves horizontally along the supporting beam 201. Each servo actuator 203 can work independently. The industrial camera 3 transmits data to the controller. After analyzing the data, the controller sends an independent instruction to each servo actuator 203, thereby controlling each servo actuator 203 to work independently. The position of each circular blade 206 can be adjusted independently. If the cloth is offset during the striping process, each circular blade 206 can automatically adjust its position according to the feedback of the industrial camera to adapt to the offset of the cloth, so that the striping effect of the cloth is better and the width of the cloth strips is more uniform.

[0026] Working process: Manually feed the fabric into the slitting mechanism. Determine the position of the fabric through the industrial camera 3. The industrial camera 3 transmits the data to the controller. The controller moves the circular blade 206 to the preset cutting position according to the servo steering gear 203. The top light source 7 and the side light source 8 are turned on to illuminate the fabric in the feeding area. After the fabric deviates, the industrial camera 3 captures the deviation amount, and the controller adjusts the position of the circular blade 206 in real time according to the deviation amount of the fabric.
