In the prior art, utility model patent application number 202022430839.2 discloses a non-woven bag surface printing device, which mainly consists of a conveyor belt and a printing screen. In use, the conveyor belt transports the non-woven bags to the printing screen for printing patterns. However, this device has the following problems: while transporting the non-woven bags via the conveyor belt, it only has the function of conveying the bags; some non-woven bags may have dust on their surface, which can affect the printing effect. Therefore, a printing feeding device that can clean the dust from the surface of the non-woven bags is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a feeding device for printing non-woven bags that can not only transport non-woven bags but also clean the dust on the surface of the non-woven fabric, ensuring the printing effect of the non-woven bags. It is convenient to use and highly practical.

[0004] This utility model discloses a feeding device for printing on non-woven bags, comprising a base plate, a belt conveyor, and a conveyor belt. The belt conveyor is fixedly installed on the upper part of the base plate, and the conveyor belt is mounted on the belt conveyor. It also includes a cleaning mechanism and a scraping mechanism, both mounted on the base plate. The cleaning mechanism has the function of cleaning dust and is located to the left of the conveyor belt. The scraping mechanism is located to the left of the cleaning mechanism and has the function of scraping. The external non-woven printing mechanism is located to the right of the belt conveyor. When it is necessary to print a pattern on the non-woven bag, the operator first passes the non-woven bag through the scraping mechanism. If the non-woven bag… Large impurities adhere to the surface of the non-woven fabric. The scraping mechanism removes these large particles, and the non-woven bag then passes through a cleaning mechanism to remove dust. The cleaned bag falls onto a conveyor belt, which then moves it to the vicinity of the printing mechanism. The worker then removes the cleaned bag from the conveyor belt and places it into the printing machine for printing. This system not only transports non-woven bags but also cleans the surface, ensuring high-quality printing. It is convenient and highly practical.

[0005] Preferably, the cleaning mechanism includes a support frame, a servo motor, a lower dust-adhesive roller, a lifting frame, an upper dust-adhesive roller, a lifting mechanism, and a transmission mechanism. The support frame is fixedly mounted on the base plate, the servo motor is fixedly mounted on the support frame, the lower dust-adhesive roller is rotatably mounted on the support frame, the power output end of the servo motor is connected to the lower dust-adhesive roller, the lower dust-adhesive roller is located on the left side of the conveyor belt, and the height of the lower dust-adhesive roller is higher than the conveyor belt. The lifting frame is slidably mounted on the support frame, the upper dust-adhesive roller is rotatably mounted on the lifting frame, the lifting frame is mounted on the lifting mechanism, and the lifting mechanism is used to lift the lifting frame. The upper dust-adhesive roller is located above the lower dust-adhesive roller, and the lower dust-adhesive roller is connected to the support frame via the transmission mechanism. The upper dust-adhesive roller is connected, and the transmission mechanism has a transmission function. When cleaning the dust on the surface of the non-woven bag, the worker puts the non-woven bag into the gap between the lower and upper dust-adhesive rollers, so that the lower and upper dust-adhesive rollers contact the upper and lower ends of the non-woven bag respectively. Then, the servo motor is turned on, and the servo motor drives the lower dust-adhesive roller to rotate. The rotating lower dust-adhesive roller causes the non-woven bag to move to the right, so that the dust on the upper and lower ends of the non-woven bag is adhered by the lower and upper dust-adhesive rollers. Then, the non-woven bag falls onto the conveyor belt for transportation. When there is too much dust on the surface of the lower or upper dust-adhesive rollers, the dust-adhesive belts on the surface of the lower and upper dust-adhesive rollers are replaced.

[0006] Preferably, the transmission mechanism includes gear A and gear B, which are fixedly mounted on the lower and upper dust-adhesive rollers, respectively, and are meshed. When the servo motor drives the lower dust-adhesive roller to rotate, the lower dust-adhesive roller drives gear A to rotate, gear A drives gear B to rotate, and gear B drives the upper dust-adhesive roller to rotate, so that the lower and upper dust-adhesive rollers rotate synchronously and in opposite directions, so that the lower and upper dust-adhesive rollers simultaneously drive the nonwoven bag to move.

The fixed frame is fixedly installed on the base plate, the support plate is fixedly installed on the upper end of the fixed frame, the lower scraper is fixedly installed on the upper end of the support plate, and the upper scraper is located above the lower scraper. There is a gap between the upper and lower scrapers. The upper scraper is installed on the height adjustment mechanism, which is used to adjust the height of the upper scraper. When conveying the nonwoven bag, the end of the nonwoven bag passes through the gap between the lower and upper scrapers and is placed between the lower and upper dust-adhesive rollers. Then, the lower and upper dust-adhesive rollers are rotated, causing the nonwoven bag to move to the right. During the rightward movement, the lower and upper scrapers remove large particles of impurities from the surface of the nonwoven bag, facilitating the cleaning of large particles of impurities from the surface of the nonwoven bag.

[0009] Preferably, the height adjustment mechanism includes a mounting frame, a screw, and a lifting plate.

This mechanism is suitable for non-woven bags of different thicknesses.

[0010] Preferably, the upper end of the lower scraper and the lower end of the upper scraper are provided with rubber layers; this arrangement reduces scratches on the nonwoven bag by the lower and upper scrapers and improves reliability.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only transport non-woven bags, but also clean the dust on the surface of non-woven fabric, ensuring the printing effect of non-woven bags, and is convenient to use and highly practical.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 5 This utility model relates to a feeding device for printing on non-woven bags, comprising a base plate 1, a belt conveyor 2, a conveyor belt 3, a cleaning mechanism, and a scraping mechanism. The belt conveyor 2 is fixedly installed on the upper end of the base plate 1, and the conveyor belt 3 is mounted on the belt conveyor 2. Both the cleaning mechanism and the scraping mechanism are mounted on the base plate 1. The cleaning mechanism has the function of cleaning dust and is located to the left of the conveyor belt 3. The scraping mechanism is located to the left of the cleaning mechanism and has the function of scraping. The external non-woven fabric printing mechanism is located to the right of the belt conveyor 2. When it is necessary to print a pattern on the non-woven bag, the operator first passes the non-woven bag through the scraping mechanism. If the non-woven bag is not properly printed, the scraping mechanism will be used to print the pattern. Large impurities adhere to the surface of the nonwoven bag. The scraping mechanism removes these large particles, and the bag then passes through a cleaning mechanism to remove dust. The cleaned bag falls onto conveyor belt 3, which then moves it to the vicinity of the printing mechanism. The worker removes the cleaned bag from the conveyor belt 3 and places it into the printing machine for printing. This system not only transports nonwoven bags but also cleans the surface, ensuring effective printing. It is convenient and highly practical.

[0021] like Figure 1 , Figure 4 and Figure 5The cleaning mechanism includes a support frame 4, a servo motor 5, a lower dust roller 6, a lifting frame 7, an upper dust roller 8, a lifting mechanism, and a transmission mechanism. The support frame 4 is fixedly mounted on the base plate 1. The servo motor 5 is fixedly mounted on the support frame 4. The lower dust roller 6 is rotatably mounted on the support frame 4. The power output end of the servo motor 5 is connected to the lower dust roller 6. The lower dust roller 6 is located to the left of the conveyor belt 3, and its height is higher than that of the conveyor belt 3. The lifting frame 7 is slidably mounted on the support frame 4. The upper dust roller 8 is rotatably mounted on the lifting frame 7. The lifting frame 7 is mounted on the lifting mechanism, which is used to lift the lifting frame 7. The upper dust roller 8 is located above the lower dust roller 6. The lower dust roller 6 is connected to the support frame 4 via a transmission mechanism. The mechanism is connected to the upper dust-adhesive roller 8, and the transmission mechanism has a transmission function. When cleaning the dust on the surface of the non-woven bag, the worker puts the non-woven bag into the gap between the lower dust-adhesive roller 6 and the upper dust-adhesive roller 8, so that the lower dust-adhesive roller 6 and the upper dust-adhesive roller 8 contact the upper and lower ends of the non-woven bag respectively. Then, the servo motor 5 is turned on, and the servo motor 5 drives the lower dust-adhesive roller 6 to rotate. The rotating lower dust-adhesive roller 6 causes the non-woven bag to move to the right, so that the dust on the upper and lower ends of the non-woven bag is stuck off by the lower dust-adhesive roller 6 and the upper dust-adhesive roller 8. Then, the non-woven bag falls onto the conveyor belt 3 for transportation. When there is too much dust on the surface of the lower dust-adhesive roller 6 or the upper dust-adhesive roller 8, the dust-adhesive belt on the surface of the lower dust-adhesive roller 6 and the upper dust-adhesive roller 8 is replaced.

[0022] like Figure 4 and Figure 5 The transmission mechanism includes gear A9 and gear B10, which are fixedly mounted on the lower dust roller 6 and the upper dust roller 8, respectively, and gear A9 and gear B10 mesh. When the servo motor 5 drives the lower dust roller 6 to rotate, the lower dust roller 6 drives gear A9 to rotate, gear A9 drives gear B10 to rotate, and gear B10 drives the upper dust roller 8 to rotate, so that the lower dust roller 6 and the upper dust roller 8 rotate synchronously, and the rotation directions of the lower dust roller 6 and the upper dust roller 8 are opposite, so that the lower dust roller 6 and the upper dust roller 8 simultaneously drive the nonwoven bag to move.

[0023] like Figure 4 and Figure 5The lifting mechanism includes a servo cylinder 11 and a lifting rod 12. The servo cylinder 11 is fixedly installed on the upper end of the support frame 4, and the lifting rod 12 is slidably installed on the support frame 4. The upper end of the lifting rod 12 is connected to the power output end of the servo cylinder 11, and the lifting frame 7 is fixedly installed on the lower end of the lifting rod 12. When it is necessary to replace the adhesive tape on the lower adhesive roller 6 and the upper adhesive roller 8, the servo cylinder 11 is turned on. The servo cylinder 11 drives the lifting rod 12 to raise the lifting frame 7, and the lifting frame 7 drives the upper adhesive roller 8 to rise, thereby increasing the gap between the lower adhesive roller 6 and the upper adhesive roller 8, which facilitates the replacement of the adhesive tape on the lower adhesive roller 6 and the upper adhesive roller 8. After the replacement is completed, the lifting frame 7 is returned to the initial height. Before the lifting frame 7 is returned to the initial height, the operator rotates the gear B10 to prevent the gear A9 from colliding with the gear B10 during the descent of the lifting frame 7, so that the gear A9 and the gear B10 mesh.

There is a gap between the upper scraper 16 and the lower scraper 15. The upper scraper 16 is installed on the height adjustment mechanism, which is used to adjust the height of the upper scraper 16. When conveying the non-woven bag, the end of the non-woven bag passes through the gap between the lower scraper 15 and the upper scraper 16 and is placed between the lower dust roller 6 and the upper dust roller 8. Then, the lower dust roller 6 and the upper dust roller 8 are rotated, which drives the non-woven bag to move to the right. During the movement to the right, the lower scraper 15 and the upper scraper 16 remove large particles of impurities from the surface of the non-woven bag, which facilitates the cleaning of large particles of impurities from the surface of the non-woven bag.

[0025] like Figure 3 The height adjustment mechanism includes a mounting frame 17, a screw 18, and a lifting plate 19. The mounting frame 17 is fixedly mounted on the upper end of the support plate 14. The screw 18 is screwed onto the upper part of the mounting frame 17. The lifting plate 19 is slidably mounted on the mounting frame 17. The upper scraper 16 is fixedly mounted on the lower end of the lifting plate 19. The lower end of the screw 18 is rotatably mounted on the lifting plate 19. When adjusting the distance between the lower scraper 15 and the upper scraper 16, the screw 18 is rotated. The rotating screw 18 adjusts the height of the upper scraper 16 through the lifting plate 19, thereby adjusting the gap between the upper scraper 16 and the lower scraper 15. This mechanism is suitable for non-woven bags of different thicknesses.
