Description

Technical Field

[0001] This utility model relates to the field of nonwoven bag production, specifically to a nonwoven bag production edge cutting device. Background Technology

[0002] Non-woven bags are bags made from non-woven fabric. They are a green product, made from non-woven fabric, a new generation of environmentally friendly material. They are moisture-proof, breathable, flexible, lightweight, non-flammable, easily degradable, non-toxic and non-irritating, available in a variety of colors, inexpensive, and recyclable.

[0003] During the production of non-woven bags, the non-woven fabric rolls are pre-wound into rolls of different widths according to the production needs of different specifications. Before the non-woven fabric rolls are sewn into non-woven bags, the edges of the rolls need to be trimmed. Traditional trimming equipment unwinds and rewinds at the same time, with a cutter placed between the unwinding and rewinding to cut the edges of the fabric. These cutters are usually fixed to ensure stable cutting. When different widths of fabric are used, the position of the cutter needs to be manually adjusted in advance. Therefore, when changing the position of the cutter, the machine needs to be stopped in advance for adjustment, and sometimes the machine needs to be recalibrated, which is relatively troublesome.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0031] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0032] Please see Figures 1 to 2 According to an embodiment of the present invention, a nonwoven bag production edge trimming device includes a frame 1. A first extension frame 2 is fixedly installed on the outer side of one end of the frame 1. A unwinding roller 3 is rotatably installed on the first extension frame 2. A steering roller 4 is rotatably installed on the top of the end of the frame 1 near the first extension frame 2. A plurality of flattening rollers 5 are installed at the center of the top of the frame 1. A top frame 6 is fixedly installed on the top of the frame 1 away from the unwinding roller 3. A support roller 7 is rotatably installed on the top frame 6. An edge trimming mechanism 8 is installed on the outer side of the end of the frame 1 near the support roller 7. A second extension frame 9 is also fixedly installed at the end of the frame 1 below the edge trimming mechanism 8. A take-up roller 10 is rotatably installed on the second extension frame 9.

[0033] The nonwoven fabric strip to be cut is pre-wound onto the unwinding roller 3. The end of the nonwoven fabric strip on the unwinding roller 3 passes through the top of the turning roller 4 and the top of the flattening roller 5 in sequence, and finally passes around the outside of the support roller 7. The cutting mechanism 8 installed at the end of the frame 1 can cut the edge of the nonwoven fabric strip outside the support roller 7. The cut nonwoven fabric strip is then wound up by the winding roller 10.

[0034] An extension rod 11 is fixedly installed on the outside of the end of the frame 1 away from the first extension frame 2, and the edge cutting mechanism 8 is fixedly installed on the extension rod 11.

[0035] The top and bottom of the frame 1 are also rotatably mounted with guide rollers 12. There are two guide rollers 12, which are respectively located on both sides of the flattening roller 5. The non-woven fabric strip to be cut passes through the bottom of the guide rollers 12 in sequence. The guide rollers 12 can ensure that the non-woven fabric strip remains flat when it passes through the top of the flattening roller 5, thereby improving the flattening effect.

[0036] A tension roller 13 is rotatably installed inside the end of the frame 1 near the second extension frame 9. The non-woven fabric strip that has been trimmed from the support roller 7 can bypass the tension roller 13 and enter the take-up roller 10, thereby ensuring the flatness of the trimmed non-woven fabric strip wound by the take-up roller 10.

[0037] like Figures 3 to 5 As shown, the edge-cutting mechanism 8 includes a horizontal plate 81 fixedly mounted on the top of the extension rod 11. A support plate 82, arranged along its length, is symmetrically mounted on the top of the horizontal plate 81. A first guide rail 83 is fixedly mounted on the top of the support plate 82, and two edge-cutting assemblies 84 are slidably mounted on the first guide rail 83. The edge-cutting assemblies 84 can perform edge-cutting operations on the non-woven bags on the support roller 7. The edge-cutting assemblies 84 can also be moved and adjusted on the first guide rail 83, thereby changing the distance between the two edge-cutting assemblies 84, which can be adaptively adjusted according to the width of the non-woven bag to be edge-cut.

[0038] A first motor 85 is installed at one end of the top of the horizontal plate 81. The output shaft of the first motor 85 is connected to a first lead screw 87 via a coupling 86. The first lead screw 87 has two threaded sections with opposite thread directions. The bottoms of the two cutting edge assemblies 84 are connected to the two threaded sections respectively. The first motor 85 drives the first lead screw 87 to rotate. When the first lead screw 87 rotates, it will drive the two cutting edge assemblies 84 to move through the two threaded sections on its outer wall.

[0039] A vertical plate 88 is also fixedly installed on the top of the horizontal plate 81. The vertical plate 88 is located at both ends of the support plate 82 and between the two support plates 82. The vertical plate 88 located between the two support plates 82 is located close to the first motor 85. The end of the first lead screw 87 is rotatably connected to the vertical plate 88 through the bearing 89.

[0040] like Figure 6 and Figure 7As shown, the trimming assembly 84 includes a movable frame 841. A first guide block 842 is fixedly mounted on the bottom of the movable frame 841 and slidably mounted on a first guide rail 83. A first threaded sleeve 843 is fixedly mounted on the bottom of the movable frame 841 and screwed onto the outside of a first lead screw 87. A second guide rail 844 is symmetrically mounted on the top of the movable frame 841 along its center. The second guide rail 844 is perpendicular to the first guide rail 83. A trimming module 848 is slidably mounted on the top of the second guide rail 844. When the first lead screw 87 rotates, the first threaded sleeve 843 can drive the movable frame 841 to move along the length of the first guide rail 83, thereby adjusting the distance between the two movable frames 841 and, consequently, the distance between the two trimming modules 848. The trimming module 848 can also move along the length of the second guide rail 844, thereby adjusting the distance between the trimming module 848 and the support roller 7, facilitating the feeding and trimming operation of the trimming module 848.

[0041] An end plate 845 is fixedly installed at one end of the top of the movable frame 841. A second motor 846 is installed on the end face of the end plate 845 away from the second guide rail 844. The output shaft end of the second motor 846 passes through the end plate 845 and is fixedly connected to a second lead screw 847. The bottom of the trimming module 848 is connected to the second lead screw 847. Similarly, the second motor 846 drives the second lead screw 847 to rotate, and the rotation of the second lead screw 847 is used to adjust the movement of the trimming module 848.

[0042] The trimming module 848 includes a transverse plate 8481, a second guide block 8482 fixedly installed at the bottom of the transverse plate 8481, the second guide block 8482 slidably installed on the second guide rail 844, an assembly frame 8483 fixedly installed at the top of the transverse plate 8481, a cutter 8484 rotatably installed at one end of the assembly frame 8483 away from the transverse plate 8481, the cutter 8484 is located near the support roller 7, and a second threaded sleeve 8485 fixedly installed at the bottom of the transverse plate 8481, the second threaded sleeve 8485 being screwed to the outside of the second lead screw 847. When the second lead screw 847 rotates, the second screw sleeve 8485 can drive the transverse plate 8481 to move, thereby adjusting the position of the cutter 8484 mounted on the top of the transverse plate 8481 via the mounting frame 8483, so that the cutter 8484 moves toward the support roller 7. When the blade of the cutter 8484 contacts the outer wall of the support roller 7, the edge of the nonwoven bag that passes over the outer wall of the support roller 7 can be cut.

[0043] Through the above-described solution of this utility model, the utility model has a simple structure and is easy to use and install. The guide roller 12 can act on the non-woven bag passing through the flattening roller 5 to ensure that the non-woven bag on the flattening roller 5 is as flat as possible. The distance between the two edge-cutting components 84 can be adjusted, and then selectively adjusted according to the width of the non-woven bag to improve adaptability. Moreover, no human intervention is required to enter the machine during the adjustment process, avoiding the tedious steps of subsequent recalibration. Furthermore, the edge-cutting module 848 can also adjust the distance between itself and the support roller 7, which facilitates the subsequent replacement and maintenance of the cutter 8484.
