Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, and in particular to a fabric positioning and cutting mechanism. Background Technology

[0002] As living standards continue to improve, clothing, food, housing, and transportation, as core parts of people's lives, are receiving increasing attention. Today, people's pursuit of beauty is stronger than ever, which is vividly reflected in their clothing choices. In the garment manufacturing industry, fabrics come in a rich variety of types and properties. As one of the three essential elements of clothing, fabric occupies a pivotal position in the industry, with different fabrics playing unique roles and possessing diverse functions.

[0003] In the garment production process, cutting large pieces of fabric into appropriate sizes is an essential step. However, current fabric cutting devices on the market have certain limitations and are relatively simple in function. Before cutting the fabric, it is often necessary to manually lay out the fabric, which is not only labor-intensive but also affects production efficiency. Moreover, when the fabric is cut by the blade, the external force applied by the blade can easily cause wrinkles and deviations in the fabric, resulting in uneven edges of the cut fabric and seriously affecting product quality. In view of this, this application specifically designs a fabric positioning and cutting mechanism. Utility Model Content

[0010] The second elastic component includes a second insert rod and a second spring.

The second positioning holes on the two crossbars are movably fitted onto the second positioning rod.

[0014] The beneficial effects of this utility model are:

[0015] When cutting the fabric, the fabric is first laid on the base. Then, the two first hydraulic rods on the support frame are controlled to push the cutting and pressing mechanism to lower the height, so that the pressing plate under the lifting plate touches the top of the fabric. Then, the adjusting components in the two flattening mechanisms are controlled so that the two flattening plates touch the top of the fabric. Then, the second motor is operated to drive the second screw to rotate. The rotation of the second screw can drive the two horizontal plates to move relative to each other at the same time, thereby driving the two flattening plates to move towards both ends of the base at the same time. Under the action of the adjusting components, the flattening plates will not press tightly against the top of the fabric. In this way, the movement of the flattening plates can lay the fabric flat on the base.

[0016] After the fabric is laid out, the first hydraulic rod is controlled to move the cutting and pressing mechanism upward. Then, the first motor is operated to drive the first screw to rotate. The rotation of the first screw can drive the support frame to move in the moving groove, thereby adjusting the position of the cutting and pressing mechanism. After the position of the cutting and pressing mechanism is adjusted, the first hydraulic rod is controlled again to make the cutting and pressing mechanism press on the fabric. Then, the linear module is controlled to drive the sliding block to move in the inner groove. The sliding block can drive the cutting blade assembly below to move. When the blade holder moves, it will separate from the extrusion plate. After the blade holder is no longer squeezed, it will move downward, so that the bottom of the blade body contacts the fabric, thereby completing the cutting of the fabric.

[0017] When the blade holder moves to the two ends of the inner groove, the extrusion plates at both ends of the inner groove extend into the openings on the side of the blade holder. The top of the extrusion plates presses against the top of the openings, causing the blade holder to move upwards. This separates the blade from the fabric, thus completing the cutting process. During the cutting process, the blade moves within the groove between the pressing plates. The pressing plates are pressed tightly against the fabric by the lifting plates, thus pressing down on the cut area of ​​the fabric and preventing the fabric from wrinkling or shifting due to the cutting of the blade.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] Please see Figures 1-9 This utility model provides a technical solution: a fabric positioning and cutting mechanism, including a base 1, a vertical plate 2 fixedly installed at the rear end of the base 1, a movable groove 3 opened on the front side of the vertical plate 2, an L-shaped support frame 4 that is movable and extends above the base 1 is arranged in the movable groove 3, and a lifting and lowering cutting and pressing mechanism 5 is arranged between the support frames 4. Two slots 6 are opened on the front side of the vertical plate 2 and above the movable groove 3. A flattening mechanism 7 that can move relative to each other is arranged in both slots 6. The two flattening mechanisms 7 are respectively located on both sides of the cutting and pressing mechanism 5. The cutting and pressing mechanism 5 can not only press the fabric cutting area, but also cut the fabric, while the two flattening mechanisms 7 can flatten the fabric as a whole before cutting, which is convenient for subsequent cutting of the fabric.

[0031] like Figure 2 and Figure 3 As shown, a first motor 31 is fixedly installed on the right side of the vertical plate 2. The output end of the first motor 31 is fixedly connected to a first screw 32 extending into the moving groove 3. A first screw hole 33 threaded onto the first screw 32 is opened on the side of the end of the support frame 4. Two first positioning holes 35 are also opened on the side of the end of the support frame 4. Two first positioning rods 34 are fixedly installed in the moving groove 3. The two first positioning rods 34 are respectively inserted into the two first positioning holes 35 at the end of the support frame 4. Two first hydraulic rods 41 are fixedly installed on the top of the support frame 4. The telescopic ends of the two first hydraulic rods 41 pass through the support frame 4 and are respectively fixedly connected to the two ends of the top of the cutting and pressing mechanism 5. By operating the first motor 31, the first screw 32 can be driven to rotate threadedly with the first screw hole 33 at the end of the support frame 4, thereby driving the end of the support frame 4 to move in the moving groove 3. The first positioning rods 34 can make the support frame 4 more stable when moving. By controlling the first hydraulic rods 41, the position and height of the cutting and pressing mechanism 5 can be adjusted.

[0032] like Figure 3 and Figure 4As shown, the cutting and pressing mechanism 5 includes a lifting plate 50, a linear module 52, a cutting blade assembly, and a pressing plate 57. The bottom of the lifting plate 50 has an inner groove 51. The linear module 52 is fixedly installed on the top of the inner groove 51, and a movable sliding block 53 is provided at the bottom of the linear module 52. The cutting blade assembly is installed at the bottom of the sliding block 53. The pressing plate 57 is installed below the lifting plate 50, and a blade groove 58 is provided in the middle of the pressing plate 57. The pressing plate 57 is connected to the lifting plate at its four corners. A second elastic component 59 is provided between the bottoms of the lifting plate 50. A disassembly port 511 is provided at the middle position of the left side of the lifting plate 50. By controlling the linear module 52, the sliding block 53 and the cutter assembly can be moved in the inner groove 51. When the lifting plate 50 descends, the pressing plate 57 below it will first contact the fabric. Then, as the lifting plate 50 continues to descend, the second elastic component 59 will be compressed into the groove 593 and the second rod groove 594 at the bottom of the lifting plate 50. In this way, the lifting plate 50 can press the pressing plate 57 against the top of the fabric, thereby fixing the middle position of the fabric, which is convenient for the subsequent flattening mechanism 7 to flatten the fabric as a whole. The cutter assembly can cut the fabric at the knife groove 58 in the middle of the pressing plate 57, and the blade 56 in the cutter assembly can be replaced through the disassembly port 511.

[0033] like Figure 6 and Figure 7 As shown, the cutting assembly includes a blade holder 54 and a blade body 56. Both ends of the top of the blade holder 54 are equipped with first elastic components 55 connected by sliding blocks 53. A mounting groove 541 is provided on the side of the blade holder 54. The top of the blade body 56 is fixedly connected to the mounting groove 541 by two bolts 561. A through-hole 542 is provided on the side of the blade holder 54. The horizontal height of the top of the inner wall of the through-hole 542 gradually increases from the middle to both ends. Extrusion plates 510, corresponding to the positions of the through-hole 542, are fixedly installed on both sides of the inner wall of the inner groove 51. The blade body 56 can be disassembled and replaced by turning the bolts 561. When the blade holder 54 moves to the positions of both ends of the inner groove 51, the extrusion plates 510 at both ends of the inner groove 51 extend into the through-hole 542 on the side of the blade holder 54. The top of the extrusion plates 510 presses against the top of the through-hole 542, causing the blade holder 54 to move upwards. This separates the blade body 56 from the fabric, achieving the purpose of retracting the blade.

[0034] like Figures 3-7As shown, the first elastic component 55 includes a first insert rod 551 and a first spring 552. The bottom ends of the sliding block 53 are provided with first rod grooves 553. The bottom end of the first insert rod 551 is fixedly connected to the top of the blade holder 54, and the top end of the first insert rod 551 is movably inserted into the first rod groove 553 at the bottom of the sliding block 53. The two ends of the first spring 552 are respectively fixedly connected to the top of the blade holder 54 and the bottom of the sliding block 53 and are sleeved on the first insert rod 551. The first elastic component 55 can connect the blade holder 54 and the sliding block 53 together. When the extrusion plate 510 extrudes the through 542, the first elastic component 55 can contract, thereby moving the blade holder 54 upward and driving the blade body 56 to move upward.

[0035] The second elastic component 59 includes a second insert rod 591 and a second spring 592. The four corners of the bottom of the lifting plate 50 are provided with grooves 593, and the top of each groove 593 is provided with a second rod groove 594. The bottom end of the second insert rod 591 is fixedly connected to the corner of the top of the pressing plate 57, and the top end of the second insert rod 591 is movably inserted into the second rod groove 594. The two ends of the second spring 592 are respectively fixedly connected to the top of the pressing plate 57 and the top of the groove 593 and are sleeved on the second insert rod 591. The second elastic component 59 can prevent the pressing plate 57 from applying excessive pressure to the fabric.

[0036] like Figure 1 , Figure 8 and Figure 9 As shown, the flattening mechanism 7 includes a crossbar 71, a flattening plate 72, and two sets of adjustment components. The flattening plate 72 is located below the crossbar 71. Adjustment components are provided between the two ends of the top of the crossbar 71 and the two ends of the top of the flattening plate 72. By pressing the fabric with the flattening plate 72 in the two flattening mechanisms 7 and moving relative to each other, the fabric on the base 1 can be flattened as a whole.

[0037] The adjusting assembly includes a sleeve 73, a second hydraulic rod 74, and a third spring 75. The sleeve 73 is fixedly installed on the top of the laying board 72, and the second hydraulic rod 74 is fixedly installed on the top of the crossbar 71. The telescopic end of the second hydraulic rod 74 passes through the crossbar 71 and is movably inserted into the sleeve 73. The third spring 75 is disposed inside the sleeve 73, and its two ends are respectively fixedly connected to the top of the laying board 72 and the telescopic end of the second hydraulic rod 74. The adjusting assembly can control the position and height of the laying board 72, and the third spring 75 can prevent the laying board 72 from squeezing the fabric too tightly, allowing the laying board 72 to move normally along the fabric.

[0038] like Figure 1 , Figure 8 and Figure 9As shown, a second motor 61 is fixedly installed on the right side of the vertical plate 2. The output end of the second motor 61 is fixedly connected to a second screw 62 extending into the two slots 6. The portions of the second screw 62 located in the two slots 6 are respectively provided with positive and negative threads. The sides of the two crossbars 71 located in the slots 6 are each provided with a second screw hole 64, and the second screw holes 64 at the ends of the two crossbars 71 are respectively threaded onto the positive and negative thread portions of the second screw 62. A second positioning hole 65 is provided on the sides of the two crossbars 71. The front side of the vertical plate 2 and located in the two slots 61 are provided with a second positioning hole 65. A second positioning rod 63 is fixedly installed at each slot 6. The second positioning holes 65 on the two crossbars 71 are movably fitted onto the second positioning rod 63. By operating the second motor 61, the second screw 62 is driven to rotate within the two slots 6. The second screw holes 64 at the ends of the two crossbars 71 are threadedly connected to the positive thread and the negative thread on the second screw 62, respectively. Therefore, the rotation of the second screw 62 can simultaneously drive the two crossbars 71 to move relative to each other, so that the two laying boards 72 move simultaneously towards both ends of the base 1, thereby laying the fabric flat on the base 1.
