Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a device for coating the outer surface of a non-woven fabric bag. Background Art

[0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments through various fiber web forming methods and consolidation technologies to form a new type of fiber product with soft, breathable and planar structure. Non-woven bags, also known as non-woven bags, are green products that are tough and durable, beautiful in shape, breathable, reusable, washable, can be screen-printed with advertisements and marks, and have a long service life.

[0003] During the laminating process of non-woven bags, due to the influence of various factors, the problem of insufficient laminating tension will occur. The existing equipment often lacks the functions of real-time monitoring and automatic correction, and cannot promptly detect and correct abnormal conditions in the laminating process. This will not only cause the laminating layer to fall off easily, bubbles or wrinkles to appear, but also affect the overall appearance and durability of the non-woven bag. Therefore, in response to the above problems, we propose a new type of non-woven bag outer surface laminating equipment. Utility Model Content

[0024] like Figure 1 and Figure 4 As shown, a mounting plate 41 is fixedly connected to the top of one of the side panels 2 near the right side, and a second material roller 42 is rotatably connected to the top of the mounting plate 41. The mounting plate 41 is for facilitating the installation of the second material roller 42 and provides a bracket for the second material roller 42 to be easily installed and fixed.

[0025] like Figure 1 and Figure 4 As shown, the front surface of one of the side panels 2 is rotatably connected to a second driven pulley 5 near the left side, and the rear surface of the second driven pulley 5 is fixedly connected to a first squeezing roller 51 through an axis. In order to provide a certain driving force to the first squeezing roller 51, the second driven pulley 5 can rotate under its action.

[0026] like Figure 1 and Figure 2 As shown, a transmission belt 33 is connected between the outer surfaces of the driving pulley 3, the first driven pulley 4 and the second driven pulley 5, and the bottom of the workbench 1 near the four corners is fixedly connected to the base 11. The transmission belt 33 can drive the movement of the driving pulley 3, the first driven pulley 4 and the second driven pulley 5 through a drive motor 22, without the need for multiple drive sources, saving energy.

[0027] like Figure 1 and Figure 3 As shown, the inner surface walls of the two side panels 2 are rotatably connected to two first guide rollers 32 near the lower right side position, and the inner surface walls of the two side panels 2 are rotatably connected to two heating rollers 53 near the middle position. The first guide rollers 32 can provide a moving guide for the non-woven bag on the first material roller 31, and the two heating rollers 53 heat the non-woven bag and the film so that the film is firmly attached to the surface of the non-woven bag.

[0030] The method of using the device and the working principle: When using the device, the unprocessed non-woven bag is placed as a whole on the first material roller 31 on the workbench 1, and the film is placed on the second material roller 42, and then the driving motor 22 on the mounting frame 21 is started. Under the action of the driving motor 22, the first material roller 31 and the driving pulley 3 on the side plate 2 are driven to rotate synchronously. At the same time, since the driving pulley 3, the first driven pulley 4 and the second driven pulley 5 are all connected by the transmission belt 33, the driving motor 22 drives the driving pulley 3 to rotate while also synchronously driving the second driven pulley 5. The second material roller 42 and the first squeezing roller 51 on the first driven pulley 4 and the second driven pulley 5 rotate. At this time, the non-woven bag will first be guided by the two first guide rollers 32 and then move to the position of the heating roller 53. At this time, the film on the second material roller 42 will be guided by the two second guide rollers 43 and move to the position of the heating roller 53. At this time, the non-woven bag and the film will be combined and coated, and the heating of the heating roller 53 will make the coating effect better. Finally, the non-woven bag with the film will be squeezed by the second squeezing roller 52 to increase the firmness of the coating. The bag is discharged through the first squeezing roller 51. During this period, the tensioning force is increased at any time by the tensioning component 6. The squeezing force received by the non-woven bag before and after the film is coated is mainly detected in real time by the pressure sensor 603 on the electric push rod 602. The pressure sensor 603 is combined with the control system to realize the automatic control of the non-woven bag coating. By presetting a suitable pressure range, when the pressure sensor 603 detects that the pressure exceeds or falls below this range, the electric push rod 602 is activated to open and close, so that the tensioning roller 605 on the U-shaped frame 604 can be automatically The pressure of the tensioning component 6 is automatically adjusted without manual intervention, which can greatly improve production efficiency and ensure the stability of the coating quality. The device has significantly improved the efficiency and quality of non-woven bag coating through intelligent design. The automated process reduces manual intervention and ensures continuous and efficient production. The real-time monitoring and automatic adjustment of the tensioning component 6 can accurately control the coating tension, effectively prevent problems such as bubbles and wrinkles, and enhance the firmness and aesthetics of the coating. In addition, the combination of heating and extrusion processes further improves the coating effect and makes the non-woven bags more durable.
