Description

Technical Field

[0001] This invention relates to the field of clothing design, and more particularly to a kraft paper cutting device for clothing design pattern making. Background Art

[0002] In the process of pattern making for clothing design, cutting kraft paper is a crucial step. Traditional kraft paper cutting devices have many drawbacks.

[0003] On the one hand, the limited methods for securing kraft paper of different sizes make it difficult to ensure the paper remains taut during cutting, thus affecting cutting accuracy. Common securing methods cannot adapt to diverse paper sizes, easily leading to paper wrinkles, misalignment, and other problems, resulting in deviations between the cut pattern and the design expectations.

[0004] On the other hand, existing cutting tools are relatively simple, typically equipped only with basic cutting scissors, which cannot meet the needs of complex pattern designs that require various shapes of rulers. Designers may need to frequently change rulers of different shapes to assist in drawing and cutting during pattern making; traditional devices cannot quickly and conveniently accomplish this task, significantly reducing work efficiency.

[0005] Furthermore, existing devices lack effective means to adhere and fix the paper during the cutting process and to precisely adjust the cutting angle, making it difficult to guarantee the stability and accuracy of the cutting process.

[0006] Moreover, existing devices often cannot monitor abnormalities in the cutting process in real time, such as the blade detaching from the paper or remaining in one place for a long time. Once these problems occur, they will not only affect the cutting quality, but may also cause unnecessary damage to the paper. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a kraft paper cutting device for clothing design pattern making.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A kraft paper cutting device for garment design pattern making includes a base, a fixed frame on the top of the base, and support legs fixed at the four corners of the bottom of the fixed frame and the top of the base.

There are two support blocks, and each pair of support blocks is rotatably connected to the lower clamping roller and the upper clamping roller respectively via bearings.

The fixed box is fixedly connected to the circular plate, and the sliding plate is slidably connected to the inside of the fixed box and extends out of the fixed box. One side of the outer wall of the sliding plate is fixedly connected to the connecting plate. The limiting frame is fixedly connected to the outer wall of the fixed box, and its inner wall has a sliding groove for the connecting plate to slide. The second electric push rod is fixedly connected to the inner wall of the limiting frame, and its output end is fixedly connected to one side wall of the connecting plate. The ruler-like tool is fixedly connected to the other side wall of the connecting plate, and its surface has multiple micro-holes. The top of the connecting plate is fixedly connected to the vacuum pump and the negative pressure sensor, and the output end of the vacuum pump is fixedly connected to the input end of the micro-holes.

[0011] Preferably, the circumferential angle adjustment assembly includes a support plate, a connecting box frame, a motor, a rotating rod, a connecting plate, a gear, a third electric push rod, and a pin plate. The base has a sliding groove for the support plate to slide. The connecting box frame is fixedly mounted on the top of the support plate. A second reciprocating screw slide is fixedly mounted inside the connecting box frame. The rotating rod is rotatably connected to the top of the support plate and the connecting box frame via a bearing. The motor is fixedly connected to the top of the support plate, and its output end is fixedly mounted to the rotating rod. Two connecting plates are provided, each with a through-hole for the rotating rod to slide. The connecting plates are fixedly connected to a slider on the second reciprocating screw slide. The gear is rotatably connected to the side wall of the connecting plate via a bearing. Multiple third electric push rods are provided, evenly arranged along the circumferential direction of the gear's inner wall. The output end of the third electric push rod is fixedly connected to the pin plate, and the rotating rod has multiple slots for the pin plate to insert into. Teeth that mesh with the gear are fixedly mounted on the outer wall of the disc.

[0012] Preferably, the ruler-like tool is fixedly equipped with a blade mechanism for cutting kraft paper. The blade mechanism includes a cutting blade connected to any guide rail, a first limiting plate, a second limiting plate, a moving plate, a first switch, an abutting slide plate, a pressing head, a feedback box, and a second switch. The first limiting plate and the second limiting plate are both fixedly connected to the ruler-like tool. The first limiting plate has a groove for the moving plate to slide, and the first switch is fixedly connected to one side wall of the moving plate.

There are multiple second switches evenly distributed on the inner wall of the feedback box, and the pressing head abuts against the second switches.

[0013] Preferably, the number of blade mechanisms is matched to the shape of the tool.

[0014] The present invention has the following beneficial effects: 1. This device, through its tension adjustment component, can precisely clamp and tighten both ends of kraft paper of different sizes. This design effectively prevents wrinkles or shifts in the paper during the cutting process, providing a stable foundation for subsequent high-precision cutting and greatly improving cutting accuracy and pattern quality.

[0015] 2. Each tool component of this device is equipped with rulers of different shapes, which can quickly move the required shape of the ruler to the position closest to the kraft paper. This allows designers to select the appropriate tool according to their needs at any time during the pattern making process, significantly improving work efficiency.

[0016] 3. This device utilizes negative pressure, allowing two sets of tool components to adsorb kraft paper from both the top and bottom. A negative pressure sensor monitors pressure changes in real time. If the kraft paper detaches during the cutting process, the negative pressure decreases, and the system can detect this promptly, allowing operators to make adjustments and ensuring the continuity and stability of the cutting process. 4. The circumferential angle adjustment component of this device is always connected to the two tool components closest to the kraft paper and drives the tool assembly to adjust. While the tool components adjust their positions, the meshing gears also adjust accordingly, thus achieving precise control of the cutting angle. This function allows designers to easily handle the cutting needs of various complex patterns, further improving the device's applicability and cutting accuracy.

[0017] 5. During the cutting process, the blade mechanism can not only detect whether the blade has detached from the kraft paper and deviated from the set cutting position, but also monitor whether the blade remains stationary in a certain position for an extended period. If any of these abnormalities occur, the device immediately sends a signal to the first electric switch in the tension adjustment component, activating the switch to release the tension adjustment component from the kraft paper, preventing damage to the paper due to abnormalities, effectively protecting the raw materials, reducing manual inspection workload, and improving the level of automation in the process.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: Refer to Figure 1 - Figure 2 The device includes a base 1, a fixed frame 2 on the top of the base 1, support legs fixed between the four corners of the bottom of the fixed frame 2 and the top of the base 1, a reciprocating screw slide fixed inside the fixed frame 2, and tension adjustment components 3 for fixing the kraft paper symmetrically arranged on the reciprocating screw slide.

[0022] The tension adjustment assembly 3 includes a clamping base plate 31, a clamping top plate 32, a lower clamping roller 33, an upper clamping roller 34, a locking plate 35, a locking rod 36, and a first electric push rod 37. The clamping base plate 31 is fixedly connected to the slider on the reciprocating screw slide, and one side wall of the clamping base plate 31 and one side wall of the clamping top plate 32 are rotatably connected by a rotating shaft and a torsion spring. Two support blocks are fixedly provided on one side wall of both the clamping base plate 31 and the clamping top plate 32. Each pair of support blocks is rotatably connected to the lower clamping roller 33 and the upper clamping roller 34 respectively through bearings. There are two locking plates 35, which are fixedly connected to the top of the clamping base plate 31 and the bottom of the clamping top plate 32 respectively. The locking rod 36 is fixedly connected to the output end of the first electric push rod 37. A support frame is fixedly provided on one side of the outer wall of the clamping base plate 31, and one side of the outer wall of the support frame is fixedly connected to the first electric push rod 37. An opening for the locking rod 36 to be inserted is penetrating through the inside of the locking plate 35.

[0023] In this embodiment: the two ends of the kraft paper are placed on the lower clamping rollers 33 of the two sets of tension adjustment components 3 respectively. The clamping top plate 32 is flipped so that the upper clamping roller 34 presses on the kraft paper. At this time, the torsion spring generates elastic force, initially clamping the paper. The first electric push rod 37 is activated, and its output end pushes the locking rod 36 into the opening of the locking plate 35, further fixing the clamping bottom plate 31 and the clamping top plate 32, ensuring that the lower clamping roller 33 and the upper clamping roller 34 tightly clamp the paper. Subsequently, the reciprocating screw slide table drives the two sets of tension adjustment components 3 to move in opposite directions, tightening the kraft paper. During this process, the tension adjustment components 3, through the rotatable clamping structure and electric locking design, can adapt to kraft paper of different sizes, achieving stable clamping and tightening, avoiding paper wrinkling and displacement, solving the problems of poor fixing effect and insufficient adaptability of traditional devices, and laying the foundation for high-precision cutting. Example 2:

[0024] Reference Figure 3 - Figure 6 The difference from Embodiment 1 is that: a first lead screw slide is fixedly provided on the top of the base 1, a second lead screw slide is fixedly provided on the slider on the first lead screw slide, and a cutting mechanism 4 for cutting kraft paper is fixedly provided on the slider on the second lead screw slide.

[0025] The cutting mechanism 4 includes a base plate 41, a first vertical rod 42, a second vertical rod 43, a tool assembly 44 for auxiliary positioning during kraft paper cutting, and a circumferential angle adjustment assembly 45 for adjusting the cutting angle of the tool assembly 44. The base plate 41 is fixedly connected to the slider on the second lead screw slide. The first vertical rod 42 and the second vertical rod 43 are both fixedly connected to the top of the base plate 41. There are two sets of tool assemblies 44, which are symmetrically arranged on the first vertical rod 42 and the second vertical rod 43, and there are multiple tool assemblies 44 in each set.

[0026] Tool assembly 44 includes a circular plate 441, a fixed box 442, a sliding plate 443, a limiting frame 444, a second electric push rod 445, a connecting plate 446, a vacuum pump 447, a negative pressure sensor 448, and a ruler-like tool 449. The circular plate 441 has a horizontally penetrating groove inside, and two circular holes are also provided inside the circular plate 441 for the first vertical rod 42 and the second vertical rod 43 to pass through, respectively, and the circular holes are connected to the horizontal groove. The fixed box 442 is fixedly connected to the circular plate 441, and the sliding plate 443 is slidably connected to the inside of the fixed box 442 and extends out of the fixed box 442. One side of the outer wall of 443 is fixedly connected to the connecting plate 446. The limiting frame 444 is fixedly connected to the outer wall of the fixing box 442, and the inner wall is provided with a sliding groove for the connecting plate 446 to slide. The second electric push rod 445 is fixedly connected to the inner wall of the limiting frame 444 and its output end is fixedly connected to one side wall of the connecting plate 446. The ruler tool 449 is fixedly connected to the other side wall of the connecting plate 446, and multiple tiny air holes are opened on the surface of the ruler tool 449. The top of the connecting plate 446 is fixedly connected to the vacuum pump 447 and the negative pressure sensor 448. The output end of the vacuum pump 447 is fixedly connected to the input end of the tiny air holes.

[0027] The circumferential angle adjustment assembly 45 includes a support plate 451, a connecting box frame 452, a motor 453, a rotating rod 454, a connecting plate 455, a gear 456, a third electric push rod 457, and a pin plate 458. A sliding groove for the support plate 451 to slide is provided on the base 1. The connecting box frame 452 is fixedly mounted on the top of the support plate 451. A second reciprocating screw slide is fixedly mounted inside the connecting box frame 452. The rotating rod 454 is rotatably connected to the top of the support plate 451 and the connecting box frame 452 via bearings. The motor 453 is fixedly connected to the top of the support plate 451, and its output end is connected to the rotating rod 454. The moving rod 454 is fixed in this configuration. There are two connecting plates 455, and a groove is passed through the center of each plate to allow the rotating rod 454 to slide. The connecting plate 455 is fixedly connected to the slider on the second reciprocating screw slide. The gear 456 is rotatably connected to the side wall of the connecting plate 455 through a bearing. There are multiple third electric push rods 457, which are evenly arranged along the circumference of the inner wall of the gear 456. The output end of the third electric push rod 457 is fixedly connected to the pin plate 458. The rotating rod 454 has multiple slots for the pin plate 458 to be inserted into. The outer wall of the disc is fixedly provided with teeth that mesh with the gear 456.

[0028] In this embodiment: according to the cutting needs, if a ruler is required, the ruler-type tools 449 in the upper group are moved to the bottom (the position closest to the top of the kraft paper) through the horizontal groove. The ruler-type tools 449 in the lower group are moved to the top (the position closest to the kraft paper) through the horizontal groove. The remaining tool components 44 are removed through the horizontal groove, rotated 180 degrees, and then reinstalled through the horizontal groove, so that the other ruler-type tools 449 do not affect the use of the ruler.

[0029] Based on the required cutting position, the second electric push rod 445 is activated, pushing the sliding plate 443 to slide within the fixed box 442, thereby moving the connecting plate 446 and the ruler tool 449. The ruler tool 449 of the desired shape is then adjusted to the position where the kraft paper needs to be cut. The vacuum pump 447 is activated, using tiny pores on the surface of the ruler tool 449 to adsorb the upper and lower surfaces of the kraft paper. A negative pressure sensor 448 monitors the adsorption pressure in real time. If the negative pressure value is abnormal (e.g., decreases), cutting can be stopped immediately, and the adsorption force adjusted to ensure the paper is stable and to avoid cutting path errors. This design enables rapid switching between various ruler tools 449, meeting the cutting needs of complex patterns. The negative pressure adsorption and monitoring functions further ensure the stability of the paper during cutting, improving operational efficiency and reliability.

[0030] Based on the position of the circular plate 441 in the tool assembly 44 used above and below, the second reciprocating lead screw slide in the circumferential angle adjustment assembly 45 is activated, driving the two connecting plates 455 to move, so that the connecting plates 455 slide on the rotating rod 454, moving until the position of the gear 456 is flush with the position of the circular plate 441. Then, the third electric push rod 457 is activated, pushing the pin plate 458 into the slot of the rotating rod 454 to fix the current angle. The support plate 451 is moved to drive the entire assembly to move, so that the gear 456 meshes with the ruler on the circular plate 441 and stops. Then, the motor 453 is activated to drive the rotating rod 454 to rotate, the rotating rod 454 drives the gear 456 to rotate, the gear 456 drives the ruler to mesh and rotate, and then drives the circular plate 441 to rotate, further driving the ruler tool 449 to rotate at an angle. During this process, the meshing transmission between gear 456 and circular plate 441 ensures precise angle adjustment and can adaptively adjust according to the position changes of each tool assembly 44, solving the problem of limited angle adjustment in traditional devices and improving the flexibility and accuracy of cutting. Example 3:

[0031] Reference Figure 7 - Figure 9 The difference from Embodiments 1 and 2 is that the ruler tool 449 is fixedly provided with a blade mechanism 5 for cutting kraft paper.

[0032] The blade mechanism 5 includes a cutting blade 51 connected to any guide rail, a first limiting plate 52, a second limiting plate 53, a moving plate 54, a first switch 55, an abutting slide plate 56, a pressing head 57, a feedback box 58, and a second switch 59. The first limiting plate 52 and the second limiting plate 53 are both fixedly connected to the ruler-like tool 449. The first limiting plate 52 has a groove for the moving plate 54 to slide, and the first switch 55 is fixedly connected to one side wall of the moving plate 54. One side wall of the cutting blade 51 is fixedly connected to the abutting slide plate 56, and the abutting slide plate 59... The 6 is inserted between the first limiting plate 52 and the second limiting plate 53, and abuts against one side wall of the limiting plate and abuts against the first switch 55. The pressing head 57 is fixedly connected to one side wall of the outer wall of the abutting slide plate 56. The feedback box 58 is fixedly connected to one side wall of the second limiting plate 53. The second limiting plate 53 and the feedback box 58 both have sliding grooves through which the pressing head 57 slides, and the pressing head 57 extends into the interior of the feedback box 58. There are multiple second switches 59 evenly distributed on the inner wall of the feedback box 58, and the pressing head 57 abuts against the second switches 59.

[0033] The number of blade mechanisms 5 matches the shape of the tool; if it is triangular, it has blades on the top three sides.

[0034] In this embodiment: After determining the cutting position of the ruler tool 449, the cutting blade 51 can be manually held or fixed on different electric guide rails. The cutting blade 51 is pulled by tension to cut the kraft paper. During use, by inserting the abutment slide plate 56 between the first limiting plate 52 and the second limiting plate 53, one side wall of the abutment slide plate 56 abuts against the first switch 55. Thus, when the blade moves, it will always be in close contact with the first switch 55 and drive the moving plate 54 to move synchronously. The pressing head 57 and the abutment slide plate 56 can be fixed by magnetic attraction or by elastic buckle. During cutting, if the blade falls off the kraft paper or deviates from the set position, the abutment slide plate 56 will rise and detach from the surface of the first switch 55, so that the first switch 55 loses contact and issues a warning signal. During normal moving cutting, the pressing head 57 will continuously trigger the second switch 59 at different positions. If the blade stays at a certain position for a long time, the pressing head 57 will continuously abut against the same second switch 59, and the second switch 59 at that point will issue an abnormal signal.

[0035] In both of the aforementioned scenarios, the system sends a signal to the first electric push rod 37, causing it to disengage the locking rod 36 from the locking plate 35. Under the action of the torsion spring, the top plate 32 is flipped, releasing the fixation on the kraft paper and preventing damage to the paper or other machine wear. This design, through the monitoring function of the blade mechanism 5, achieves intelligent monitoring and anomaly protection of the cutting process, reducing manual intervention and improving the safety and reliability of the device.

[0036] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
