Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and particularly relates to an automatic material cutting mechanism. Background Art

[0002] In the processing processes of many woven materials, in order to facilitate subsequent processing operations and transportation work, the materials are usually wound up. In the production process of some finished products, long strip-shaped materials need to be cut into segments and then packaged.

[0003] Currently, the commonly used material cutting mechanisms mostly unwind the material while cutting. However, when cutting the material, the material needs to be temporarily stopped from being transported, which means that the unwinding process needs to be adjusted accordingly, so that the cutting mechanism cannot continuously unwind the material all the time. Otherwise, it will cause material accumulation or excessive pulling, affecting the subsequent cutting effect. This kind of adaptive adjustment is generally observed and operated manually, and then the unwinding of the woven material is adjusted. This not only increases the labor intensity of workers, but also is prone to misoperation, affecting production efficiency and product quality. Therefore, an automatic material cutting mechanism is provided to solve the above problems. Utility Model Content

Detailed Description of the Embodiment

[0040] The following further describes the present application in detail Figure 1-6 in conjunction with the attached drawings.

[0041] An embodiment of the present application provides an automatic cutting mechanism.

[0042] Referring to Figure 1-2 , the automatic cutting mechanism includes an unwinding device 1, a detection device 2, a conveying device 3, a cutting device 4 and a fixing table 5. The woven material sequentially passes through the unwinding device 1, the detection device 2, the conveying device 3 and the cutting device 4. Among them, the woven material to be cut is unwound by the unwinding device 1, the tension of the woven material is detected by the detection device 2, and the conveying device 3 is used to convey the woven material to a fixed position, and the cutting device 4 is used to cut the woven material.

[0043] Reference Figure 1-2 , the detection device 2 includes a mounting frame 21, a cross bar 22 and sensors 23. The cross bar 22 is slidably connected to the mounting frame 21. A fabric is movably connected below the cross bar 22. The cross bar 22 can move up and down along the mounting frame 21 through the tension of the fabric. The sensors 23 are fixedly connected to the mounting frame 21. The number of sensors 23 is two and they are mirror-symmetrical from top to bottom. The cross bar 22 is located between the two sensors 23. The two sensors 23 are used to detect the up and down movement range of the cross bar 22 on the mounting frame 21. The fabric is in a tensioned state and fits on the cross bar 22 and is located between the two sensors 23. By measuring the movement range of the cross bar 22 with the sensors 23, when the cross bar 22 is close to the upper sensor 23, the control program will accelerate the unwinding. When the cross bar 22 is close to the lower sensor 23, the control program will decelerate the unwinding. It can detect the tension of the fabric during transportation, and thus detect the tension of the fabric unwound by the unwinding device 1. When adjustment is needed, through the cooperation of the controller and the unwinding device 1, the unwinding device 1 adjusts the unwinding speed to adjust the tension of the fabric during transportation, so that the fabric maintains a constant tension throughout the transportation process, which is convenient for subsequent accurate cutting of the fabric, and improves the processing efficiency and product quality.

[0044] Reference Figure 3-4 , the conveying device 3 includes a fixing plate 31, a guiding component 32, an adjusting component 33 and a conveying component 34. The guiding component 32 and the adjusting component 33 are both arranged on the fixing plate 31. The fabric is conveyed in sequence through the detection device 2, the guiding component 32, the adjusting component 33 and the conveying component 34. The guiding component 32 includes a guiding rod 321, a baffle 322, a movable plate 323, a bidirectional screw 324 and a support rod 325. The baffle 322 is connected to the guiding rod 321 by bolts. The guiding rod 321 is fixedly connected to the fixing plate 31. Move the baffle 322 on the guiding rod 321. After determining the appropriate position of the baffle 322, abut the baffle 322 against the guiding rod 321 by bolts, which can guide the fabric in the horizontal direction and is also applicable to fabrics of different widths to ensure the straightness of the fabric during transportation. The movable plate 323 is threadedly connected to the bidirectional screw 324 and is slidably connected to the support rod 325. The rotation of the bidirectional screw 324 drives the two movable plates 323 to move along the support rod 325. After the movable plate 323 moves to the appropriate position on the support rod 325, rotate the bolt on the movable plate 323 to make the movable plate 323 abut against the support rod 325, and the position of the movable plate 323 can be fixed. This not only provides a supporting role during the fabric transportation process, but also realizes the flexible adjustment of the fabric transportation width through the linkage between the movable plate 323 and the bidirectional screw 324.

[0045] Among them, the adjusting component 33 includes a handle 331, a first pressing roller 332, a second pressing roller 333 and an elastic member 334. The handle 331 is rotatably connected to the fixing plate 31, the handle 331 is rotatably connected to the first pressing roller 332. The two ends of the elastic member 334 are respectively connected to one side of the handle 331 and one side of the fixing plate 31 to provide elastic force when the handle 331 rotates. The second pressing roller 333 is rotatably connected to the fixing plate 31. The fabric is conveyed between the first pressing roller 332 and the second pressing roller 333. By rotating the handle 331, the first pressing roller 332 can be driven to move, which is convenient for manual operation of the first pressing roller 332, so that the first pressing roller 332 and the second pressing roller 333 can better abut against each other, better press the fabric, and maintain stable conveyance.

[0046] Reference Figure 5-6 , the conveying component 34 includes a fixing frame 341, a first driving member 342, a driving roller 343, a driven roller 344, an adjusting member and a guiding plate 345. The fixing frame 341 is fixedly connected to the fixing table 5. The driving roller 343 and the driven roller 344 are both arranged on the fixing frame 341. The adjusting member is arranged on the fixing frame 341 to drive the driven roller 344 and the driving roller 343 to abut against each other. The first driving member 342 is a motor, which drives the driving roller 343 to rotate through a synchronous belt. One side of the fixing frame 341 is fixedly connected to the guiding plate 345. The fabric is conveyed along the guiding plate 345 to between the driving roller 343 and the driven roller 344. The guiding plate 345 further includes a connecting plate and two baffle plates. The two baffle plates are connected to the connecting plate, which can effectively guide the conveying path of the fabric, prevent the fabric from shifting or wrinkling during the conveying process, and improve the conveying accuracy and stability of the fabric.

[0047] Among them, the adjusting member includes an adjusting block, an adjusting screw, an elastic member and a guiding plate. The adjusting block is slidably connected to the fixing frame. The adjusting screw is threadedly connected to the fixing frame. The adjusting screw is rotatably connected to the adjusting block. The two ends of the elastic member are respectively fixedly connected to the adjusting block and the guiding plate, which can provide a certain buffering effect. The two ends of the conveying roller are respectively rotatably connected to the two guiding plates. By operating the adjusting member, the height adjustment of the driven roller can be realized.

[0048] Reference Figure 5-6 , the cutting device 4 includes a bearing frame 41, a cutting driving source 42, a connecting block 43, a cutting knife 44, a spring 45 and a pressing plate 46. Among them, the bearing frame 41 is fixedly connected to the fixing table 5. The cutting driving source 42 is arranged on the bearing frame 41. The connecting block 43 is connected to the output shaft of the cutting driving source 42. The cutting knife 44 is connected to the connecting block 43. The spring 45 is connected to the connecting block 43. The pressing plate 46 is connected to the spring 45, which can absorb the impact force during the cutting process, ensure the smoothness of the cutting, and reduce the wear of mechanical components. The pressing plate 46 can be made of plastic material, which has good wear resistance and impact resistance, can effectively fix the fabric at the cutting position, and improve the cutting accuracy.

[0049] Among them, by rotating the output shaft of the cutting material driving source 42 for a fixed number of turns or an angle, at this time, the synchronous belt conveys a fixed length, that is, a fixed length of woven material is conveyed. When each reaches the set value, the synchronous belt stops rotating, and the pressing plate 46 and the cutting knife 44 are synchronously driven downward. The pressing plate 46 first abuts against and presses the woven material. With further driving, the woven material is pressed tightly. At this time, the cutting knife 44 cooperates with the bearing frame 41 to cut the passing woven material. After cutting, it resets, and the synchronous belt can continue to drive the driving roller 343 and the driven roller 344 to convey the woven material, improving the cutting efficiency and having relatively high cutting accuracy, and being able to ensure that the lengths of the woven materials are consistent.

[0050] The implementation principle of an automatic cutting mechanism in an embodiment of the present application is as follows:

[0051] Through the cooperation of the detection device 2, the conveying device 3, and the unwinding device 1, this device can achieve efficient and precise control of the tension of the woven material during conveyance, thereby improving the cutting accuracy and production efficiency. At the same time, it is more convenient to accurately control the conveyance and stop of the woven material during cutting, and then cooperate with the cutting device 4 to perform synchronous cutting, realizing an efficient and precise cutting process, ensuring that the lengths of each section of the woven material are the same, and further ensuring the high quality and high efficiency of the entire processing flow.

[0052] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
