[0003] Currently, most existing nonwoven bag making machines are single-color printing, which cannot meet modern aesthetic standards. Furthermore, when it is necessary to change the printed pattern, the template roller needs to be removed. However, removing the template roller with existing devices is very troublesome and time-consuming. In addition, during the processing, the nonwoven fabric may wrinkle or shift during transportation. Directly processing nonwoven fabric with wrinkles or shifts will greatly increase the probability of defective products. Therefore, a nonwoven bag making machine production line is needed.

[0013] 3. Beneficial Effects Compared with the prior art, the advantages of this invention are: (1) This scheme supports the entire device through the setting of the operating table, the setting of the conveying device can convey the rolled non-woven fabric, the two-color printing device can perform two-color printing on the non-woven fabric, the ultrasonic embossing and perforating device can emboss and perforate the printed non-woven fabric, then the fabric synchronous conveying device will synchronously convey the fabric, the ultrasonic left and right edge sealing device will seal the left and right sides of the fabric, then the left and right edge trimming waste winding device will wind up the left and right sides of the fabric, the forming device will then shape the fabric, and then the ultrasonic sealing device will seal the fabric. The material is sealed, then cut with a cross-cutting blade. This device is fully automated and can perform two-color printing. Patterns can be customized and easily changed; simply replace the template roller. To change the pattern, first rotate the clamping rod counter-clockwise, causing it to rise. Then pull down the locking device to unlock the control sleeve. After unlocking, pull the control sleeve; the clamping rod will slide into the groove, releasing its clamping limit on the template roller. Pull the template roller upwards to remove it. Place the new template roller between the two placement slots, reset the control sleeve, and then rotate the clamping rod clockwise. The clamping rod will descend and clamp the template roller in place. Next, the locking device will re-engage into the drive sleeve to secure the control sleeve, thus improving the clamping rod's hold on the template roller. Then, start motor one, which will drive the drive gear to rotate. The drive gear, through the driven gear, will then drive the template roller to rotate. The coloring box will color the template roller. As the non-woven fabric passes through the template roller, the template roller will print on the non-woven fabric, achieving single-pass coloring. The colored non-woven fabric will then enter the next printing press. The process involves secondary dyeing. During operation, motor two is activated, which drives the flattening roller to rotate. The flattening roller flattens the non-woven fabric and drives it to the right. In the process, the flattening roller drives the laying roller to rotate. The rotation of the two laying rollers stretches the fabric and removes wrinkles, thereby reducing the probability of defective products. In addition, the flattening roller drives the pressure roller to rotate via a belt. The rotation of the pressure roller, in conjunction with the heating plate, has an ironing effect on the fabric, further reducing wrinkles and the probability of defective products, thus improving the flatness of the equipment.

[0014] (2) This solution uses the spring force to drive the drive rod upward. After the drive rod moves upward, it will fall into the locking hole, thereby achieving the purpose of locking the control sleeve on the drive sleeve.

[0015] (3) This solution can print on the fabric through the color roller. The two ends of the color roller are fixedly connected to the limiting block and the placement groove. The placement groove will limit the limiting block, thereby achieving the positioning function and improving the accuracy of the device.

[0016] (4) The operating ring fixedly connected to the top of the clamping rod in this solution allows the user to rotate the clamping rod, improving the portability of the device. The clamping block fixedly connected to the bottom of the clamping rod can increase the friction, thereby improving the clamping effect on the template roller.

[0017] (5) This solution uses a limiting ring on the back drive sleeve and a rotating ring fixedly connected to one end of the front drive sleeve to limit the two drive sleeves, reduce the displacement of the drive sleeves, improve the printing progress, and increase the yield of the device.

[0018] (6) This solution can support the drive rod by setting a fixed ring, and then the transmission can be achieved by the contact between the drive rods, thereby achieving the purpose of transmission. Attached Figure Description

Then, the fabric synchronous conveying device 4 will synchronously convey the fabric. The ultrasonic left and right edge sealing device 5 will seal the left and right sides of the fabric. Then, the left and right edge trimming waste winding device 6 will wind up the edge trimming waste on the left and right sides of the fabric. The forming device 7 will then shape the fabric. Finally, the ultrasonic sealing device... Step 8 seals the fabric, and step 9 cuts the fabric. This device is fully automated and can print in two colors. Patterns can be customized and easily changed; simply replace the template. To change the pattern, simply replace the template roller 22. First, rotate the clamping rod 21 counterclockwise, and it will rise. Then, pull down the locking device 20 to unlock the control sleeve 19. After unlocking, pull the control sleeve 19, and the clamping rod 21 will slide into the slide groove 18, thus losing its clamping limit on the template roller 22. Pull the template roller 22 upwards to remove it. Then, place the new template roller 22 into the two placement slots 17. In between, the control sleeve 19 is reset, and then the clamping rod 21 is rotated clockwise. The clamping rod 21 will descend and clamp and fix the template roller 22. Then, the locking device 20 will re-engage into the drive sleeve 14 to fix the control sleeve 19, thereby improving the fixing effect of the clamping rod 21 on the template roller 22. Then, the motor 15 is started, which drives the drive gear 16 to rotate. Then, the drive gear 16 drives the template roller 22 to rotate through the driven gear 161. The coloring box 23 will color the template roller 22.

During the operation, the second motor 31 is started.Motor 31 drives the flattening roller 25 to rotate, which flattens the non-woven fabric and drives it to the right. During this process, the flattening roller 25 drives the spreading roller 26 to rotate. The rotation of the two spreading rollers 26 stretches the fabric, removing wrinkles and reducing the probability of defective products. Furthermore, the flattening roller 25 drives the pressure roller 29 to rotate via a belt.

[0031] Working Principle: First, the operating table 10 supports the entire device. The conveying device 1 transports the rolled non-woven fabric. The two-color printing device 2 performs two-color printing on the non-woven fabric. The ultrasonic embossing and perforating device 3 embosses and perforates the printed non-woven fabric. Next, the fabric synchronous conveying device 4 transports the fabric synchronously. The ultrasonic left and right edge sealing device 5 seals the left and right sides of the fabric. Then, the left and right edge trimming waste collection device 6 collects the edge trimming waste from the left and right sides of the fabric. The forming device 7 then shapes the fabric. Finally, the ultrasonic sealing device 8 seals the fabric. Finally, the cross-cutting device 9 cuts the fabric. This device can achieve full automation, and... This equipment can perform two-color printing, and the patterns can be customized. Pattern changes are convenient; simply replace the template. When a pattern change is needed, only the template roller 22 needs to be replaced. First, rotate the clamping rod 21 counterclockwise, and the clamping rod 21 will rise. Then, pull down the locking device 20 to unlock the control sleeve 19. After unlocking the control sleeve 19, pull it. After pulling the control sleeve 19, the clamping rod 21 will slide into the slide groove 18, and the clamping rod 21 will lose its clamping limit on the template roller 22. Pull the template roller 22 upward to remove it. Then, place the new template roller 22 between the two placement slots 17, reset the control sleeve 19, and then rotate the clamping rod 21 clockwise. The clamping rod 21 will descend and clamp the template roller 22 in place. Next, the locking device 20 will re-engage into the drive sleeve 14 to fix the control sleeve 19, thereby improving the fixing effect of the clamping rod 21 on the template roller 22. Then, the motor 15 is started, which drives the drive gear 16 to rotate. The drive gear 16 then drives the template roller 22 to rotate through the driven gear 161. The coloring box 23 will color the template roller 22. When the non-woven fabric passes through the template roller 22, the template roller 22 will print on the non-woven fabric, thereby achieving single coloring. Then, the colored non-woven fabric will enter the next printing machine 12 for secondary coloring. During the operation, the motor 21 is started, which drives the flattening roller 25 to rotate. The flattening roller 25 will flatten the non-woven fabric and drive it to the right. During the process, the flattening roller... The flattening roller 25 drives the flattening roller 26 to rotate. The rotation of the two flattening rollers 26 stretches the fabric, removing wrinkles and reducing the probability of defective products. During the process, the flattening roller 25 drives the pressure roller 29 to rotate via a belt. The rotation of the pressure roller 29, in conjunction with the heating plate 30, irons the fabric, further reducing wrinkles and the probability of defective products. This improves the flatness of the fabric and solves the problems of existing non-woven bag making machines, which generally only offer single-color printing and cannot meet modern aesthetic standards. Furthermore, changing the printed pattern requires removing the template roller 22, which is cumbersome and time-consuming in existing machines.Non-woven fabric may wrinkle or shift during transport. Processing non-woven fabric with wrinkles or shifts directly significantly increases the likelihood of defective products in the equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
