Description
Technical Field
[0001] The present invention relates to the technical field of multi-layer cutting tables, and in particular to a multi-layer cutting table capable of inkjet printing. Background Art
[0002] With the advancement of technology, automatic cutting machines have become increasingly popular. Automatic cutting machines are automatic cutting equipment used in the textile, clothing, leather and other industries. Automatic cutting machines can quickly cut fabrics. However, existing automatic cutting machines rely on manual pre-marking when cutting: After the fabric is laid, before cutting, the cutting path, internal hole positions, alignment points, grain direction and other information must be clearly marked on the fabric surface. Currently, this marking work is almost entirely dependent on manual operation (using chalk, drawing powder, markers, stickers, etc.). Time-consuming: For complex patterns or large-scale laying materials, manual line drawing and positioning takes a lot of time, becoming a bottleneck in the entire cutting process. Error-prone: The accuracy of manual line drawing and positioning is affected by the worker's skills and fatigue, and it is easy to produce deviations, resulting in cutting errors or inaccurate alignment. Poor flexibility: Once the material is laid, if the cutting plan or marking needs to be modified, manual modification is extremely difficult and may even require re-laying the material.
[0003] The lack of inkjet functionality is a key bottleneck that restricts its efficiency and intelligence. This is not just a problem of "cutting" itself, but a problem of the efficiency of the entire cutting preparation process. Summary of the Invention
[0004] The purpose of the present invention is to provide a multi-layer cutting table capable of inkjet printing, so as to solve the following technical problem: the lack of inkjet function leads to low cutting efficiency.
[0005] The purpose of the present invention can be achieved through the following technical solutions: A multi-layer cutting table capable of inkjet printing comprises an operating platform and a movable frame movable along the longitudinal direction thereof, wherein the movable frame is provided with a multi-layer cutting table assembly movable along the transverse and vertical directions thereof; The multi-layer cutting table assembly includes a multi-layer cutting table head and an inkjet mechanism. The inkjet mechanism includes an adapter mounting plate connected to the multi-layer cutting table head. A fixed plate is provided on the adapter mounting plate. An ink cartridge rack is slidably connected to the fixed plate. An ink head is installed in the ink cartridge rack.
[0006] As a further solution of the present invention: a fixing frame is fixedly mounted on the fixing plate, a driving mechanism is mounted on the fixing frame, and the driving mechanism is used to drive the ink cartridge holder and the ink head to move up and down.
[0007] As a further solution of the present invention: the driving mechanism is a cylinder structure.
[0008] As a further solution of the present invention: the driving mechanism is a motor screw structure.
[0009] As a further solution of the present invention: a guide rail is fixedly mounted on the fixed plate, an ink cartridge holder is connected to the guide rail via a slider, and an ink cartridge holder and a photoelectric sensor are fixedly mounted on the ink cartridge holder.
[0010] As a further solution of the present invention, a control system is also included, which is used to identify the cutting path and control the driving mechanism to cut along the cutting path. The specific control system includes: A standard acquisition unit is used to acquire the inkjet image and its location imported into the system by the user and perform standard analysis; The vision unit is used to acquire the inkjet image on the fabric to be cut placed on the cutting table, and the real-time distance between the upper limit point, lower limit point, median point and the origin of the coordinate system corresponding to the acquired inkjet image are marked as real-time upper limit distance, real-time lower limit distance and real-time median distance respectively; and the real-time upper limit distance, real-time lower limit distance and real-time median distance are transmitted to the processing unit.
[0011] As a further solution of the present invention: the standard analysis method is: obtaining the standard inkjet image input by the user and its positional relationship with the cutting table, selecting feature points of the inkjet image to specify the point origin; The origin is used as the origin of the coordinate system, and the horizontal and vertical movement directions of the cutting are marked as the X axis and Y axis respectively. Then the edge line of the inkjet image is mapped into the coordinate system, and the edge line refers to the edge of the corresponding inkjet image; Get the position of the edge line in the coordinate system, then select at least three points from the edge line whose distances from the origin satisfy the farthest, closest, and median points, respectively. Mark the farthest point as the upper limit point, and the closest point as the lower limit point. The median point is the point whose distance from the origin is equal to the median of the distances from the upper and lower limit points to the origin. The distances between the corresponding upper limit point, lower limit point, median point and the origin of the coordinate system are marked as standard upper limit distance, standard lower limit distance and standard median distance; and the standard upper limit distance, standard lower limit distance and standard median distance are transmitted to a processing unit.
[0012] As a further solution of the present invention: the specific analysis method of the processing unit is: Obtain the differences between the standard upper limit distance, standard lower limit distance, standard median distance and the corresponding real-time upper limit distance, real-time lower limit distance, real-time median distance, and mark them as upper limit difference, lower limit difference, and median difference respectively; When any two of the upper limit difference, lower limit difference and median difference exceed X1, it means medium wrinkles appear, and the staff will be automatically reminded to check the fabric to be cut; When any of the upper limit difference, lower limit difference and median difference exceeds X2, it indicates that error wrinkles have occurred, and the staff will be automatically reminded to check the fabric to be cut.
[0013] Beneficial effects of the present invention: This invention utilizes an inkjet mechanism installed on the head of a multi-layer cutting table, enabling inkjet printing. The inkjet system, integrated into or above the cutting table, automatically, quickly, and accurately prints the cutting outlines, internal hole positions, alignment crosshairs, grain lines, piece numbers, and production information from the CAD design directly onto the finished surface. This saves time and effort: hours of manual work can be reduced to minutes or even less, significantly reducing labor costs and improving efficiency and quality. Furthermore, the control system achieves a higher level of automation, enabling automatic identification and adjustment based on the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0017] See also Figure 1-4 As shown, the present invention is a multi-layer cutting table capable of inkjet printing, comprising an operating platform 1 and a movable frame 2 that moves longitudinally thereof, wherein the movable frame 2 is provided with a multi-layer cutting table assembly 3 that moves transversely and vertically thereof; The multi-layer cutting table assembly 3 includes a multi-layer cutting table head 31 and an inkjet mechanism 32. The inkjet mechanism 32 includes an adapter mounting plate 321 connected to the multi-layer cutting table head 31. A fixed plate 322 is provided on the adapter mounting plate 321. A cartridge holder 327 is slidably connected to the fixed plate 322. An ink head 328 is installed in the cartridge holder 327.
[0018] A fixing frame 234 is fixedly mounted on the fixing plate 322 , and a driving mechanism 325 is mounted on the fixing frame 234 . The driving mechanism 325 is used to drive the ink cartridge frame 327 and the ink head 328 to move up and down.
[0019] The driving mechanism 325 is a cylinder structure. The driving mechanism 325 is a motor screw structure. Both can drive the ink cartridge rack 327 to move up and down, and different driving methods are used according to needs.
[0020] A guide rail 323 is fixedly mounted on the fixing plate 322 . An ink cartridge holder 326 is connected to the guide rail 323 via a slider. An ink cartridge holder 327 and a photoelectric sensor 329 are fixedly mounted on the ink cartridge holder 326 .
[0021] The specific working process is: The entire assembly is mounted on the multi-layer cutting machine head through an adapter mounting plate; the ink cartridge holder 327 and the ink head 328 are driven up and down by the driving mechanism 325; the photoelectric sensor 329 senses the distance from the fabric and stops the driving mechanism 325 to spray ink, and after the ink spraying is completed, the driving mechanism 325 rises.
[0022] The system also includes a control system for identifying a cutting path and controlling a drive mechanism to cut along the cutting path. The specific control system includes: The standard acquisition unit is used to acquire the inkjet image and its location imported by the user into the system and perform standard analysis. The specific method is as follows: Obtain the standard inkjet image entered by the user and its positional relationship with the cutting table, select feature points on the inkjet image to specify the point origin, where the specified point is arbitrarily specified by the administrator; The origin is used as the origin of the coordinate system, and the horizontal and vertical movement directions of the cutting are marked as the X axis and Y axis respectively. Then the edge line of the inkjet image is mapped into the coordinate system, and the edge line refers to the edge of the corresponding inkjet image; Get the position of the edge line in the coordinate system, then select at least three points from the edge line whose distances from the origin satisfy the farthest, closest, and median points, respectively. Mark the farthest point as the upper limit point, and the closest point as the lower limit point. The median point is the point whose distance from the origin is equal to the median of the distances from the upper and lower limit points to the origin. Mark the distances between the corresponding upper limit point, lower limit point, median point and the origin of the coordinate system as a standard upper limit distance, a standard lower limit distance and a standard median distance; transmit the standard upper limit distance, the standard lower limit distance and the standard median distance to a processing unit; The vision unit is used to acquire the inkjet image of the fabric to be cut placed on the cutting table, and the real-time distances between the upper limit point, lower limit point, median point and the origin of the coordinate system corresponding to the acquired inkjet image are marked as real-time upper limit distance, real-time lower limit distance and real-time median distance respectively; transmitting the real-time upper limit distance, the real-time lower limit distance, and the real-time median distance to a processing unit; The processing unit is used to perform deviation analysis. The specific analysis method is as follows: Obtain the differences between the standard upper limit distance, standard lower limit distance, standard median distance and the corresponding real-time upper limit distance, real-time lower limit distance, real-time median distance, and mark them as upper limit difference, lower limit difference, and median difference respectively; When any two of the upper limit difference, lower limit difference and median difference exceed X1, it means medium wrinkles appear, and the staff will be automatically reminded to check the fabric to be cut; When any of the upper limit difference, lower limit difference, and median difference exceeds X2, it indicates an error wrinkle, and the staff is automatically reminded to check the fabric to be cut. Here, X1 and X2 are both preset values, and the value of X1 is less than or equal to 0.75 times X2. Generally, in actual production, X1 can be set to 0.2 cm, and the corresponding X2 value can be set to 0.3 cm. This can also be set by the administrator according to the required accuracy of different materials. Of course, as another embodiment of the present application, the deviation analysis method in the system is different, specifically: When the situation mentioned in the above embodiment arises where a worker needs to inspect the fabric to be cut, the worker to be cut is not notified first. Instead, the inkjet image and its position imported into the system by the user are divided into several equally spaced cutting points along the edge line, with the distance between each two cutting points being a preset distance. Get several split points, and then get the distances of the split points from the origin in the standard coordinate system established under the data imported into the system, and mark all distances as standard distances; Then, the real-time distance between the origin and the original point is obtained with the help of the visual unit; Obtain the difference between several standard distances and real-time distances, and mark them as real-time differences; The point where the real-time difference exceeds X1 is marked as a deviation point, and the point where it is equal to X1 is marked as a standard point; Obtain the deviation point and locate the wrinkle area based on the deviation point, which is the angle area between the deviation point and the origin.
[0023] The specific working process is: 1. Take the clothing design file drawn by PLT or professional clothing CAD, make the pattern and use super nesting software to generate CUT format cutting file with cutting path and specified inkjet content; 2. Import the CUT format file into the output control system of the Orui multi-layer cutting machine and adopt the working process of the above control system; 3. Lay out the fabric, send it to the cutting area of the multi-layer cutting table, and cover it with film; 4. Adjust the machine and start cutting; 5. Start the negative pressure pump, align the origin, spray the number first, and then cut.
[0024] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
