[0002] Textiles are products made from processed and woven textile fibers. They are divided into two categories: woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles. Ancient silk fabrics were basically named according to fabric structure, fabric pattern, and fabric color. When testing the weaving method and toughness of textiles, samples need to be selected for cutting testing.

[0004] In the current existing technology, when the cloth needs to be cut, the cutting length needs to be adjusted manually. During the manual adjustment process, the forces on both ends of the cloth may be different, resulting in cloth wrinkles. When adjusting manually, if you want to accurately cut the length, you need to align it carefully. Therefore, when adjusting the cutting length, it takes a lot of energy and time. Moreover, the two processes of adjusting the length and pressing the cloth need to be performed in steps, and the two processes do not have a linkage effect. They need to be operated in sequence based on the experience of the staff, which makes the operation not simple.

[0005] To this end, the present invention provides a cutting device and a cutting method for textile testing samples. Summary of the invention

DETAILED DESCRIPTION

[0049] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0050] See also Figure 1 - Fig.10The present invention provides a cutting device for textile testing samples, comprising: a workbench 1; a base 47, fixedly connected to the top of the workbench 1; a plurality of guide rollers 471, all of which are rotatably connected to the top of the base 47; two pressure rollers 5, respectively arranged at the two ends of the base 47, and a driving mechanism is arranged on one side; a clamping mechanism is arranged on one side of the base 47; the clamping mechanism comprises a moving frame 6, a clamping plate 61, a photoelectric sensor 64 and a displacement sensor 66; the bottom of the moving frame 6 is slidably connected to the top of the workbench 1 through two electric slide rails 63; the bottom of the moving frame 6 is fixedly connected to an electric push rod 65, and the output end of the electric push rod 65 passes through the moving frame 6 is fixedly connected with a clamping plate 61, and four second sliding rods 62 are fixedly connected to the top of the movable frame 6, and the clamping plate 61 is slidably connected to the four second sliding rods 62; the clamping plate 61 and a side wall of the movable frame 6 are both inserted in the base 47 in cooperation; a photoelectric sensor 64 is fixedly connected to one end of the top of the movable frame 6; a displacement sensor 66 is fixedly connected to the bottom of the movable frame 6; the photoelectric sensor 64 and the side wall of the base 47 are on the same plane; the photoelectric sensor 64 is electrically connected to the electric push rod 65; the driving mechanism includes a third motor 511, a mounting frame 57, a second reciprocating screw rod 58 and a support 59; the displacement sensor 66 is electrically connected to the third motor 511.

[0051] The clamping mechanism provided by the present invention is used to clamp and adjust the cloth when in use.

[0052] During the first clamping, the cloth on the cloth-winding shaft 22 needs to be pulled to the position of the clamping plate 61 through the fixed roller 31 and the movable roller 32, and by turning on the electric push rod 65, the output end of the electric push rod 65 drives the clamping plate 61 to move downward to clamp one end of the cloth, and then drives the electric slide rail 63 to move, and under the action of the electric slide rail 63 and the displacement sensor 66, one end of the cloth is moved to the set position, and the movable frame 6 stops moving at this time; because the displacement sensor 66 is electrically connected to the third motor 511, by turning on the third motor 511, the output shaft of the third motor 511 drives the second reciprocating screw rod 58 to rotate, and the movable plate 510 is driven to move downward through the second reciprocating screw rod 58, and the side plate 51 and the pressure roller 5 are driven to move downward through the movable plate 510, so that the cloth is fixed on the base 47, and the cutting knife 46 is driven to cut;

[0053] After the cutting is completed, the second clamping is performed, and the pressure roller 5 is appropriately adjusted upward. By turning on the second motor 56, the output shaft of the second motor 56 drives the connecting rod 52 to rotate. Through the cooperation of the rotating wheel 53 and the belt 54, the two connecting rods 52 rotate synchronously, and the connecting rod 52 drives the pressure roller 5 to rotate. Through the cooperation of the pressure roller 5 and the guide roller 471, one end of the cloth is conveyed to the clamping plate 61. When one end of the cloth is aligned with the photoelectric sensor 64, the output end of the electric push rod 65 is driven by the photoelectric sensor 64 to drive the clamping plate 61 downward. The electric slide rail 63 is driven to move to clamp one end of the cloth, and then the electric slide rail 63 is driven to move. Under the action of the electric slide rail 63 and the displacement sensor 66, one end of the cloth is moved to a set position, and the moving frame 6 stops moving at this time; the third motor 511 is controlled to start, and the output shaft of the third motor 511 drives the second reciprocating screw rod 58 to rotate, and the second reciprocating screw rod 58 drives the moving plate 510 to move downward, and the moving plate 510 drives the side plate 51 and the pressure roller 5 to move downward, so that the cloth is fixed on the base 47, and the cutting knife 46 is driven to cut;

[0054] In this way, multiple samples are cut for testing; the clamping operation and the pressing operation of the pressure roller 5 are linked together through the displacement sensor 66, thereby improving the automation and continuity of the cutting device; through the clamping mechanism, it is ensured that the forces on both ends of the cloth are consistent, and it is convenient to accurately control the cutting length, thereby improving the applicability of the cutting device.

[0055] Furthermore, if Figure 1 and Figure 8 As shown, the mounting frame 57 is fixedly connected to one end of the top of the workbench 1, and a reciprocating screw is rotatably connected between the workbench 1 and the mounting frame 57 through a bearing. A threaded groove is provided on the top of the reciprocating screw, and a movable plate 510 is connected to the outer thread of the threaded groove. A side plate 51 is fixedly connected to the side wall of the movable plate 510, and the pressure rollers 5 are rotatably connected to the side plate 51 through a connecting rod 52; two pillars 59 are fixedly connected between the workbench 1 and the mounting frame 57, and the movable plate 510 slides on the two pillars 59.

[0056] The second reciprocating screw rod 58 provided by the present invention is used to adjust the height of the pressure roller 5 when in use. Since the displacement sensor 66 is electrically connected to the third motor 511, when the displacement sensor 66 moves to the set position, the third motor 511 is turned on by controlling the system program, and the second reciprocating screw rod 58 is driven to rotate by the output shaft of the third motor 511, and the movable plate 510 is driven to move downward by the second reciprocating screw rod 58, and the side plate 51 is driven to move downward by the movable plate 510, and the pressure roller 5 is moved downward by the side plate 51, so that the cloth is fixed on the base 47. When the movable plate 510 moves, the movable plate 510 slides on the pillar 59, and the pillar 59 limits the movable plate 510, the side plate 51 and the pressure roller 5 to move in a stable state.

[0057] Furthermore, if Figure 8 As shown, one end of the connecting rod 52 passes through the side plate 51 and is fixedly connected to a rotating wheel 53; a belt 54 is sleeved between the two rotating wheels 53; an L-shaped plate 55 is fixedly connected to the outer wall of the side plate 51, and a second motor 56 is fixedly connected to the L-shaped plate 55, and the output shaft of the second motor 56 is fixedly connected to the end of one of the connecting rods 52; the second motor 56 is electrically connected to the photoelectric sensor 64.

[0058] The rotating wheel 53 and the belt 54 provided by the present invention are used to convey cloth when in use. By turning on the second motor 56, the output shaft of the second motor 56 drives the connecting rod 52 to rotate, and the connecting rod 52 drives the connected rotating wheel 53 to rotate. The rotating wheel 53 drives another rotating wheel 53 to rotate through the belt 54, and another connecting rod 52 is driven to rotate through another rotating wheel 53, and the pressure roller 5 is driven to rotate through the connecting rod 52. Through the cooperation of the pressure roller 5 and the guide roller 471, one end of the cloth is conveyed to the clamping plate 61. When one end of the cloth is aligned with the photoelectric sensor 64, the second motor 56 stops working, thereby realizing the function of accurately conveying the cloth.

[0059] Furthermore, if Figure 5 As shown, a fixed frame 4 is provided on one side of the base 47, and the fixed frame 4 is fixedly connected to the workbench 1. A first motor 41 is fixedly connected to the fixed frame 4, and an output shaft of the first motor 41 is fixedly connected to a first reciprocating screw rod 42, and both ends of the first reciprocating screw rod 42 are rotatably connected to the fixed frame 4 through bearings; a moving block 44 is threadedly connected to the first reciprocating screw rod 42, and an electric push rod 45 is fixedly connected to the bottom of the moving block 44, and an output end of the electric push rod 45 is fixedly connected to a cutting knife 46 through a knife holder; two guide rods 43 are fixedly connected to the fixed frame 4, and the moving block 44 is slidably connected to the two guide rods 43.

[0060] The cutting knife 46 provided by the present invention is used for cutting cloth when in use. After the cloth is fixed, the first motor 41 needs to be turned on. The first motor 41 drives the first reciprocating screw 42 to rotate through the output shaft, and the first reciprocating screw 42 drives the moving block 44 to reciprocate. The moving block 44 drives the electric push rod 45 and the cutting knife 46 to move. The cloth is quickly cut by the cutting knife 46, and the electric push rod 45 is used to adjust the height of the cutting knife 46.

[0061] Furthermore, if Figure 6 and Figure 7As shown, the middle part of the base 47 is slidably connected to the cutting seat 472 through four first sliding rods 475, and a groove 473 is opened in the middle part of the cutting seat 472, and the groove 473 cooperates with the cutting knife 46; the outer side of the first sliding rod 475 is sleeved with a third spring 474, and the third spring 474 is fixed between the cutting seat 472 and the base 47.

[0062] When the cutting seat 472 provided by the present invention is in use, during the cutting process, the cutting knife 46 cooperates with the cutting seat 472, and under the action of the third spring 474 and the first slide bar 475, the cutting seat 472 slides vertically downward. When the cutting is completed, under the action of the third spring 474, the cutting seat 472 moves upward to push the cloth upward to prevent the cloth from being clamped in the cutting seat 472.

[0063] Furthermore, if Figure 1 and Figure 2 As shown, two fixed seats 2 are fixedly connected to one end of the top of the workbench 1 away from the electric slide rail 63, and the fixed seats 2 are hinged with mounting seats 21. Semi-bearing seats are provided on the inner walls of the fixed seats 2 and the mounting seats 21; and cloth rolling shafts 22 are commonly inserted into several of the semi-bearing seats.

[0064] The mounting seat 21 and the fixing seat 2 provided by the present invention are used to fix the cloth winding shaft 22 when in use. The cloth winding shaft 22 is fixed by placing the two ends of the cloth winding shaft 22 in the mounting seat 21 and the fixing seat 2. Semi-bearing seats are provided on the inner walls of the mounting seat 21 and the fixing seat 2, and the semi-bearing seats facilitate the rotation of the cloth winding shaft 22 to unwind the cloth.

[0065] Furthermore, if Figure 2 and Figure 3 As shown, two fixing plates 23 are fixedly connected to the top of the mounting seat 21, and a handle 231 is rotatably connected between the two fixing plates 23 through a pin shaft, and a cam block 235 is fixedly connected to the bottom of the handle 231; a sliding cavity 237 is opened in the mounting seat 21, and a limiting rod 232 is slidably connected in the sliding cavity 237, and the bottom of the limiting rod 232 is inserted in the top of the fixing seat 2; the top of the limiting rod 232 is in contact with the cam block 235; the outer side of the limiting rod 232 is sleeved with a first spring 236, and the two ends of the first spring 236 are respectively fixed to the limiting rod 232 and the bottom inner wall of the sliding cavity 237.

[0066] Since the cut textile samples are used for testing, the cloth rolling shaft 22 is replaced frequently. The limiting rod 232 provided by the present invention is used to fix the mounting seat 21 and the fixing seat 2 when in use. During installation, by pressing the handle 231 downward, the handle 231 presses the limiting rod 232 downward through the cam block 235, and the bottom of the limiting rod 232 is inserted into the fixing seat 2, so that the mounting seat 21 and the fixing seat 2 are fixed together.

[0067] During disassembly, the handle 231 is lifted upwards, and under the action of the first spring 236, the limiting rod 232 moves upwards rapidly, and the bottom of the limiting rod 232 leaves the fixing seat 2, thereby facilitating the separation of the fixing seat 2 and the mounting seat 21 to complete the disassembly.

[0068] Furthermore, if Figure 2 As shown, a fixing rod 233 is fixedly connected to the top of the mounting seat 21 , and a rotating block 234 is rotatably connected to the fixing rod 233 via a pin shaft. The rotating block 234 is arranged above the handle 231 .

[0069] The rotating block 234 provided by the present invention is used to fix the handle 231 when in use. After the handle 231 is pressed, the fixing base 2 and the mounting base 21 are fixedly connected together. By rotating the rotating block 234, the rotating block 234 is rotated above the handle 231 to fix the handle 231 to prevent the handle 231 from automatically moving upward under external force, causing the cloth rolling shaft 22 to lose fixation.

[0070] Furthermore, if Figure 4 As shown, two fixed blocks 3 are provided between the cloth winding shaft 22 and the base 47, and the fixed blocks 3 are fixedly connected to the workbench 1, and a fixed roller 31 is rotatably connected between the two fixed blocks 3 through a bearing; a driving motor is provided on one side of the fixed roller 31; a movable roller 32 is provided above the fixed roller 31; a sliding opening is opened on the fixed seat 2, and a vertical rod 34 is fixed in the sliding opening; a slider 33 is slidably connected to the vertical rod 34, and a second spring 35 is sleeved on the outer side of the vertical rod 34, and the two ends of the second spring 35 are respectively fixed to the slider 33 and the bottom inner wall of the sliding opening; the two ends of the movable roller 32 are rotatably connected to the slider 33 through a bearing.

[0071] The movable roller 32 provided by the present invention is used to convey cloth of different thicknesses when in use. By passing one end of the cloth between the fixed roller 31 and the movable roller 32, under the action of the second spring 35, the movable roller 32 is finely adjusted in the vertical direction to facilitate the conveyance of cloth of different thicknesses.

[0072] Furthermore, if Fig.11 As shown, a method for cutting textile test samples comprises the following steps:

[0073] S1: During the first clamping, the cloth on the cloth rolling shaft 22 needs to be pulled to the position of the clamping plate 61 through the fixed roller 31 and the movable roller 32;

[0074] S2: By turning on the electric push rod 65, the electric push rod 65 drives the clamping plate 61 to clamp one end of the cloth, and then moves the one end of the cloth to a set position;

Under the action of the electric slide rail 63 and the displacement sensor 66, one end of the cloth is moved to the set position, and the movable frame 6 stops moving at this time; since the displacement sensor 66 is electrically connected to the third motor 511, by turning on the third motor 511, the first The output shaft of the third motor 511 drives the second reciprocating screw 58 to rotate, and the second reciprocating screw 58 drives the movable plate 510 to move downward, and the movable plate 510 drives the side plate 51 and the pressure roller 5 to move downward, so that the cloth is fixed on the base 47, and the cutting knife 46 is driven to cut; after the cutting is completed, the second clamping is performed, and the pressure roller 5 is adjusted upward appropriately, and the second motor 56 is turned on, and the output shaft of the second motor 56 drives the connecting rod 52 to rotate, and through the cooperation of the rotating wheel 53 and the belt 54, the two connecting rods 52 rotate synchronously, and the connecting rod 5 2 drives the pressure roller 5 to rotate, and through the cooperation of the pressure roller 5 and the guide roller 471, one end of the cloth is conveyed to the clamping plate 61. When one end of the cloth is aligned with the photoelectric sensor 64, the output end of the electric push rod 65 is driven by the photoelectric sensor 64 to drive the clamping plate 61 to move downward to clamp one end of the cloth, and then drive the electric slide rail 63 to move. Under the action of the electric slide rail 63 and the displacement sensor 66, one end of the cloth is moved to the set position, and the moving frame 6 stops moving at this time; the third motor 511 is controlled to start, and the output shaft of the third motor 511 drives the second The reciprocating screw 58 rotates, and the movable plate 510 is driven to move downward through the second reciprocating screw 58, and the side plate 51 and the pressure roller 5 are driven to move downward through the movable plate 510, so that the cloth is fixed on the base 47, and the cutting knife 46 is driven to cut; in this way, a plurality of samples are cut for testing; the clamping operation and the pressing operation of the pressure roller 5 are linked together through the displacement sensor 66, so as to improve the automation and continuity of the cutting device; through the clamping mechanism, it is ensured that the forces on both ends of the cloth are consistent, and it is convenient to accurately control the cutting length, thereby improving the applicability of the cutting device.

[0081] The cloth rolling shaft 22 is fixed by placing both ends of the cloth rolling shaft 22 in the mounting seat 21 and the fixing seat 2, and the inner walls of the mounting seat 21 and the fixing seat 2 are both provided with semi-bearing seats, which facilitate the rotation of the cloth rolling shaft 22 to unwind the cloth; since the samples of the cut textiles are used for testing, the cloth rolling shaft 22 is replaced frequently, and during installation, the handle 231 is pressed downward, and the handle 231 presses the limit rod 232 downward through the cam block 235, and the bottom of the limit rod 232 is inserted into the fixing seat 2, and the mounting seat 21 and the fixing seat 2 are fixed. together; when disassembling, lift the handle 231 upwards, and under the action of the first spring 236, the limiting rod 232 moves upwards rapidly, and the bottom of the limiting rod 232 leaves the fixing seat 2, thereby facilitating the separation of the fixing seat 2 and the mounting seat 21 to complete the disassembly; after pressing the handle 231, the fixing seat 2 and the mounting seat 21 are fixedly connected together, and by rotating the rotating block 234, the rotating block 234 is rotated to the top of the handle 231 to fix the handle 231 to prevent the handle 231 from automatically moving upwards under external force, causing the cloth rolling shaft 22 to lose its fixation.
