Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, specifically a fixed-length cutting mechanism for a fabric spreading machine. Background Technology

[0002] In the textile and apparel industries, fabric spreading machines are key equipment for achieving efficient fabric spreading. With the increasing demand for production automation and precision, the requirements for the accuracy and efficiency of fixed-length cutting of fabric after spreading are becoming higher and higher. Traditional fabric spreading machine cutting mechanisms have problems such as large positioning deviation, low cutting efficiency, and complex operation, making it difficult to meet diverse production needs. Therefore, it is urgent to design a precise, efficient, and easy-to-operate fixed-length cutting mechanism for fabric spreading machines.

[0003] According to a patent application published on the internet (authorization announcement number: CN222613820U), "This utility model discloses a fabric cutting mechanism with neat cuts, belonging to the field of fabric cutting technology. It includes an operating table, with four support rods fixedly mounted at the bottom of the operating table, a square groove opened at the top of the operating table, and a motor fixedly mounted on the outer side of the operating table. By shaking the handle, the pressure plate is rotated, thereby moving the pressure plate downward until it contacts the fabric, thus stably clamping the fabric and ensuring that the fabric will not shift its position randomly during cutting, thereby ensuring the flatness of the cut. By driving the motor, the lead screw is rotated, and then the sliding plate and the fabric slide at the top position of the operating table through the slider, thereby moving the fabric to be cut to the position below the cutting blade for cutting. This solves the problem of existing devices requiring manual repositioning for secondary cutting, thus avoiding the problems of insufficient efficiency and accuracy of manual repositioning."

[0004] Based on the above, the applicant believes the following deficiencies exist:

This device solves the problem that existing devices require manual relocation for secondary cutting, thus avoiding the problems of insufficient efficiency and accuracy of manual relocation. However, this device cannot perform fabric cutting work with fixed lengths, and the overall cutting accuracy is low with large positioning deviations. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution: Example 1

[0026] Please see Figure 1-4A fixed-length cutting mechanism for a fabric spreading machine includes a cutting table 1, a fabric flattening mechanism 5 and a fixed-length cutting mechanism 6.

[0027] The fabric length cutting mechanism 6 includes a first fixed base 61, which is fixedly connected to the left and right sides of the bottom front end of the cutting table 1. A bidirectional screw 62 is rotatably connected to the inner end of the first fixed base 61. A servo motor 63 is installed on the right end of the first fixed base 61. A second fixed base 64 is fixedly connected to the left and right sides of the bottom rear end of the cutting table 1. A slide rod 65 is fixedly connected to the inner end of the second fixed base 64. A slider 66 is provided on the surface of the bidirectional screw 62 and the slide rod 65. A first movable frame 67 and a second movable frame are fixedly connected to the outer end of the slider 66. 68. Infrared ray sensor transmitters 671 are installed on the middle sections of the left and right sides of the inner end of the first moving frame 67. Infrared ray sensor receivers 681 are installed on the middle sections of the left and right sides of the inner side of the second moving frame 68. A main hydraulic cylinder 69 is installed at the center of the bottom of both the first moving frame 67 and the second moving frame 68. A main hydraulic telescopic column 691 is provided at the bottom of the main hydraulic cylinder 69. A blade holder 692 is fixedly connected to the bottom of the main hydraulic telescopic column 691. A cutting blade 601 is installed at the bottom of the blade holder 692. The front and rear ends of the left and right sides of the first moving frame 67 and the second moving frame 68 are also equipped with infrared ray sensor transmitters 671. An auxiliary fixing base 602 is fixedly connected, and a horizontal plate 603 is fixedly connected to the inner end of the auxiliary fixing base 602. Auxiliary hydraulic cylinders 604 are installed at the front and rear ends of the top of the horizontal plate 603. An auxiliary hydraulic telescopic column 605 is provided at the bottom end of the auxiliary hydraulic cylinder 604, and a positioning pressure plate 606 is installed at the bottom end of the auxiliary hydraulic telescopic column 605. After the fabric is placed on the surface of the cutting table 1, the fabric fixed-length cutting mechanism 6 can be activated to cut the fabric to a fixed length. The distance between the first moving frame 67 and the second moving frame 68 is changed by the rotation of the bidirectional screw 62 driven by the servo motor 63. The infrared ray sensor transmitter 671 and the infrared ray sensor receiver 681 determine the precise distance between the first moving frame 67 and the second moving frame 68, thereby completing the fixed length cutting of the fabric. Since the transmitter and receiver of the infrared ray sensor transmitter 671 and the infrared ray sensor receiver 681 are flush with the cutting edge of the cutting blade 601, this mechanism can complete precise fixed-length cutting and can meet the cutting work of various different lengths. The infrared ray sensor transmitter 671 and the infrared ray sensor receiver 681 use the PTM10-12 measuring light curtain.

[0028] The bidirectional screw 62 is fixedly connected to the left output end of the servo motor 63. Both ends of the surface of the bidirectional screw 62 and the slide bar 65 are provided with sliders 66. The sliders 66 are threaded to the surface of the bidirectional screw 62 and slidably connected to the surface of the slide bar 65.

[0029] The main hydraulic telescopic column 691 is driven by the main hydraulic cylinder 69, and the auxiliary hydraulic telescopic column 605 is driven by the auxiliary hydraulic cylinder 604. The first moving frame 67 is set at the top left end of the cutting table 1, and the second moving frame 68 is set at the top right end of the cutting table 1.

[0030] There are two sets of infrared ray sensor transmitter 671 and infrared ray sensor receiver 681. The infrared ray sensor transmitter 671 and infrared ray sensor receiver 681 correspond to each other. Both the transmitter and receiver of the infrared ray sensor transmitter 671 and infrared ray sensor receiver 681 are flush with the bottom end of the cutting blade 601. Example 2

[0031] Please see Figure 1-4 Based on Embodiment 1, the fabric flattening mechanism 5 further includes a support 51, which is fixedly connected to the front and rear ends of the left and right sides of the top of the cutting table 1. The inner end of the support 51 is rotatably connected to a fabric transport roller 52. A first control motor 53 is installed on the front of the support 51. A fixing plate 54 is fixedly connected to the front and rear ends of the left side of the top of the cutting table 1. A flattening and cleaning roller 55 is installed on the inner end of the fixing plate 54. A second control motor 551 is installed on the front of the fixing plate 54. The flattening and cleaning roller 55 is fixedly connected to the output end of the back of the second control motor 551. The fabric is placed through the fabric transport roller 52 and the first control motor 53. Before cutting, the fabric passes between two sets of flattening and cleaning rollers 55. The flattening and cleaning rollers 55 flatten and clean the surface of the fabric to prevent surface debris and wrinkles from affecting the cutting accuracy. When used in conjunction with the fabric fixed-length cutting mechanism 6, the cutting accuracy of the device is greatly improved.

[0032] The cutting table 1 is fixedly connected to four corner feet 2 at the bottom. The cutting table 1 is fixedly connected to a side frame 3 at the left end of the front. The main control unit 4 is installed on the top of the side frame 3.

[0033] In actual operation, when this device is used, the fabric is placed through the fabric transport roller 52 and the first control motor 53. Before cutting, the fabric passes between two sets of flat cleaning rollers 55. The flat cleaning rollers 55 clean the surface of the fabric to prevent surface debris and wrinkles from affecting the cutting accuracy. When used in conjunction with the fabric fixed length cutting mechanism 6, the cutting accuracy of the device is greatly improved.

[0034] After the fabric is placed on the cutting table 1, the fabric length-fixed cutting mechanism 6 can be activated to cut the fabric to a fixed length. The servo motor 63 drives the bidirectional screw 62 to rotate, changing the distance between the first moving frame 67 and the second moving frame 68. The precise distance between the first moving frame 67 and the second moving frame 68 is determined by the infrared ray sensor transmitter 671 and the infrared ray sensor receiver 681, thus completing the length-fixed cutting of the fabric. Since the transmitter and receiver of the infrared ray sensor 671 and the infrared ray sensor receiver 681 are both connected to the cutting blade 601... With the blades flush, this mechanism can perform precise fixed-length cutting and can meet various cutting needs. After the fabric is cut to the desired length, the auxiliary hydraulic cylinder 604 drives the auxiliary hydraulic telescopic column 605 to press down. The positioning pressure plate 606 presses down both ends of the fabric at the cutting point to prevent the fabric from shifting during cutting. The main hydraulic cylinder 69 drives the main hydraulic telescopic column 691 to press down and the cutting blade 601 precisely cuts the fabric. After cutting, the main control unit 4 controls the device to reset, and the fabric and the cut section can be removed from the cutting table 1 for recycling.
