[0024] In this way, when the surface of the non-woven fabric is cut, the third driving motor 43 is started first, the output end of the third motor drives the conveying shaft 41 to rotate, and the conveying belt 42 drivingly connected on the surface of the conveying shaft 41 starts to run, then the non-woven fabric to be cut is placed on the conveying belt 42 for conveying, at this time the second driving motor 21 and the hot pressing rod 23 are started, the hot pressing rod 23 starts to heat the compression roller 22, and the output end of the second motor drives the compression roller 22 and the hot pressing rod 23 to rotate, then the third electric push rod 18 is started, the output end of the third electric push rod 18 moves downward or upward, the surface of the compression roller 22 is in contact with the surface of the non-woven fabric, and under the continuous conveying of the conveying belt 42, the compression roller 22 irons and flattens the surface of the non-woven fabric conveyed.

[0025] In this way, the second driving motor 21 is started to run, the output end of the second driving motor 21 drives the compression roller 22 and the hot pressing rod 23 to rotate, and the hot pressing rod 23 is started to automatically heat, which irons and flattens the surface of the non-woven fabric in the conveying process, avoids wrinkles, affects subsequent cutting processing, improves the functionality and functionality, and according to the thickness of the non-woven fabric to be cut, the third electric push rod 18 is driven, the output end of the third electric push rod 18 drives the compression roller 22 and the hot pressing rod 23 to move up and down on the sliding rod 25 to the appropriate position, so that the device can adapt to the flattening and ironing of non-woven fabrics of different thicknesses, and the practicability of the device is improved.

[0026] Please refer toFigure 1 and Figure 2 The cutting mechanism 3 comprises a first driving motor 31, a cutting knife 32, a screw rod 33, a moving block 34 and a pressing assembly 35, support frames 5 are arranged on both sides of the chassis 1, the first driving motor 31 is fixedly installed on the support frame 5, a through groove 6 is formed in the upper surface of the support frame 5, the screw rod 33 is arranged in the through groove 6, and the output end of the first driving motor 31 is fixedly connected with one end of the screw rod 33, the moving block 34 is slidingly connected on the screw rod 33, a first electric push rod 7 is fixedly connected with the lower end of the moving block 34, the cutting knife 32 is fixedly installed on the output end of the first electric push rod 7, limit grooves 12 are formed in the inner sides of both ends of the support frame 5, limit blocks 13 are slidingly connected in the limit grooves 12, the pressing assembly 35 comprises a second electric push rod 351 and a pressing plate 352, the pressing plate 352 is arranged between the support frames 5, and both ends of the pressing plate 352 are fixedly connected with the limit blocks 13, the second electric push rod 351 is fixedly installed on the lower surface of the top of the support frame 5, and the output end of the second electric push rod 351 is fixedly connected with the pressing plate 352, a strip-shaped hole 14 is formed in the pressing plate 352, and the width of the strip-shaped hole 14 is greater than the width of the cutting knife 32.

[0027] In this way, when the conveyor belt 42 conveys the non-woven fabric pressed and flattened by the ironing device to below the cutting knife 32, the third driving motor 43 is stopped at this time to stop the rotation of the conveyor belt 42, and then the first driving motor 31 is started to rotate, so that the output end of the first driving motor 31 drives the moving block 34 to move left and right on the screw rod 33, at this time the second electric push rod 351 is driven, so that the output end of the second electric push rod 351 drives the pressing plate 352 to move downward to press the surface of the non-woven fabric, then the first electric push rod 7 is driven, so that the output end of the first electric push rod 7 drives the cutting knife 32 to pass through the strip-shaped hole 14 and abut against the surface of the non-woven fabric, then the cutting knife 32 is moved left and right to complete the processing and cutting of the non-woven fabric, when the cutting is completed, the conveyor belt 42 is started to convey the cut non-woven fabric away, and the subsequent non-woven fabric is continuously cut.

[0028] The effect of such an arrangement is that the first drive motor 31 drives the moving block 34 to slide left and right on the screw rod 33, while the first electric push rod 7 pushes the cutting knife 32 to abut against the surface of the non-woven fabric, thereby driving the cutting knife 32 to move left and right on the surface of the non-woven fabric to cut, which improves the traditional cutting method of the cutting knife 32 pressing the non-woven fabric straight up and straight down, thereby avoiding the cutting knife 32 pressing the surface of the non-woven fabric when cutting the non-woven fabric, causing the two ends of the non-woven fabric to shrink inward, resulting in wrinkles on the surface, thereby causing the size of the processed cloth bag to be inaccurate. At the same time, during the cutting of the non-woven fabric by the cutting knife 32, the second electric push rod 351 is driven to press the non-woven fabric tightly with the pressing plate 352, thereby reinforcing the cutting position of the non-woven fabric and further improving the accuracy of the size of the non-woven fabric bag.

[0029] Optionally, the bottom frame 1 is provided with a sliding groove 8 at both ends of the surface, and a sliding block 9 is slidably connected in the sliding groove 8, and both ends of the support frame 5 are fixedly installed on the sliding block 9. Threaded holes 10 are also provided on both sides of the top end of the sliding block 9, and threaded studs 11 are threadedly connected in the threaded holes 10, and the ends of the threaded holes 10 are located at the bottom of the sliding groove 8.

[0031] From the above, the working principle of the present application is as follows:

[0032] When cutting the surface of the non-woven fabric, first start the third drive motor 43 to drive the output end of the third motor to rotate the transmission shaft 41, so that the transmission belt 42 connected in transmission on its surface starts to run, then place the non-woven fabric to be cut on the transmission belt 42 for transmission, at this time start the second drive motor 21 and the hot pressing rod 23, so that the hot pressing rod 23 starts to heat the compression roller 22, and the output end of the second motor will drive the compression roller 22 and the hot pressing rod 23 to rotate, then start the third electric push rod 18, and the output end of the third electric push rod 18 moves downward or upward, so that the surface of the compression roller 22 contacts the surface of the non-woven fabric. Under the continuous transmission of the transmission belt 42, the compression roller 22 will iron and flatten the surface of the non-woven fabric transmitted;

[0033] When the conveying belt 42 conveys the non-woven fabric after ironing and flattening to below the cutting knife 32, the third driving motor 43 is stopped at this time to stop the rotation of the conveying belt 42, and then the first driving motor 31 is started to rotate, so that the output end of the first driving motor 31 drives the moving block 34 to move left and right on the screw rod 33, at this time the second electric push rod 351 is driven, so that the output end of the second electric push rod 351 drives the pressing plate 352 to move downward to press the non-woven fabric, then the first electric push rod 7 is driven, so that the output end of the first electric push rod 7 drives the cutting knife 32 to pass through the strip-shaped hole 14 and abut against the surface of the non-woven fabric, then under the left and right movement of the cutting knife 32, the processing and cutting of the non-woven fabric are completed, when the cutting is completed, the conveying belt 42 is started to convey the cut non-woven fabric away, and the subsequent non-woven fabric continues to be cut.

[0034] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
