Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to an automatic fabric cutting machine. Background Technology

[0002] In the fabric processing of the textile industry, the fabric cutting process involves cutting rolls of fabric to specific length or quantity requirements.

[0003] Traditional fabric cutting methods rely primarily on manual operation, with workers using scissors or manual cutting tools to cut fabric according to measured length markings. This method has several drawbacks. On the one hand, manual cutting is inefficient and cannot meet the needs of large-scale production; on the other hand, manual operation has a large margin of error, resulting in inconsistent fabric lengths after cutting, affecting product quality and subsequent processing. Therefore, an automatic fabric cutting machine is proposed to address these issues. Utility Model Content

The top rear end of the workbench 1 is vertically connected to the bottom of a support frame 2. A fabric roll 3 is mounted on the top of the support frame 2. One end of the fabric roll passes through a dust removal mechanism 4, around a rotating roller 5, and through a cutting mechanism 7 to connect to the inside of a clamping and adjusting mechanism. The dust removal mechanism 4 includes a dust removal box 41 located in the middle of the support frame 2. A first dust removal roller 42 is installed inside the rear half of the dust removal box 41. The left end of the rotating rod of the first dust removal roller 42 is connected to the output end of a first motor 43 via a coupling. A second dust removal roller 44 is provided inside the front half of the dust removal box 41. The left end of the rotating rod of the second dust removal roller 44 is connected to the output end of a second motor 45 via a coupling. The right end of the dust removal box 41... A negative pressure box 46 is provided, with its right end connected to the left end of an exhaust pipe 48. An exhaust fan 47 is installed inside the exhaust pipe 48, and a filter screen 49 is installed inside the right end of the negative pressure box 46. The front and rear sides of the left end of the negative pressure box 46 are connected to the front and rear ends of a dust collector 41 through a ventilation pipe 410. A first motor 43 can drive the first dust collector roller 42 to rotate, and a second motor 45 can drive the second dust collector roller 44 to rotate. The first dust collector roller 42 and the second dust collector roller 44 rotate in opposite directions, which can roll up the dust and debris on the cloth. When the exhaust fan 47 is started, the air flow inside the negative pressure box 46 increases and forms a negative pressure. The negative pressure box 46 sucks away the debris and dust attached to the dust collector roller 42 and the second dust collector roller 44 through the ventilation pipe 410.

[0020] The outer sides of the first dust removal roller 42 and the second dust removal roller 44 are equipped with brushes to facilitate the removal of dust and debris from the fabric.

[0022] The cutting mechanism 7 includes a top plate 71 installed at the top front end of the support plate 6. A first hydraulic rod 72 is installed on the top of the top plate 71. The telescopic end of the first hydraulic rod 72 is fixedly connected to the top of the lower pressure plate 73. The front side of the lower pressure plate 73 is welded to the rear side of the cutting frame 74. A second hydraulic rod 75 is installed on the top of the cutting frame 74. The telescopic end of the second hydraulic rod 75 is fixedly connected to the top of the knife holder 76. A cutting knife 77 is installed at the bottom of the knife holder 76. A cutting groove 9 is provided directly below the cutting knife 77. The first hydraulic rod 72 drives the lower pressure plate 73 to press down, and the fabric will be pressed down. The second hydraulic rod 75 drives the knife holder 76 and the cutting knife 77 to descend, which can cut the fabric flat.

[0023] The clamping and adjusting mechanism includes track grooves 81 at both ends of the worktable 1. A threaded rod 82 is installed inside the track groove 81. The front end of the threaded rod 82 is connected to the output end of the adjusting motor 83 via a coupling. The outer side of the threaded rod 82 is threadedly connected to the threaded holes inside the bottom sliders at both ends of the clamping base 84. The top of the clamping base 84 is fixedly connected to the bottom of the top frame 85. A third hydraulic rod 86 is installed on the top of the top frame 85. The bottom of the third hydraulic rod 86 is fixedly connected to the top of the clamping plate 87. When the operator places one end of the fabric on the base plate of the clamping base 84, the third hydraulic rod 86 drives the clamping plate 87 to descend, fixing the position of one end of the fabric. The adjusting motor 83 drives the threaded rod 82 to rotate, which in turn moves the clamping base 84, automatically adjusting the required cutting length of the fabric. By controlling the number of rotations of the threaded rod 82, the moving distance of the clamping base 84 can be controlled, improving the accuracy of the fabric cutting length.

[0024] When in use, the operator places one end of the fabric on the base plate of the clamping frame 84. The third hydraulic rod 86 drives the clamping plate 87 to descend, fixing the position of one end of the fabric. The adjusting motor 83 drives the threaded rod 82 to rotate, which in turn drives the clamping frame 84 to move, thereby automatically adjusting the length of the fabric to be cut. The first hydraulic rod 72 drives the lower pressure plate 73 to press down, pressing the fabric. The second hydraulic rod 75 drives the blade holder 76 and the cutting blade 77 to descend, which can cut the fabric flat.
